    [0001] 1 sequencing system and method for at least one preparation station. FIELD OF THE INVENTION The field of the invention is that of logistics.
    [0002] The present invention more specifically relates to a sequencing system for at least one preparation station. Such a system is configured to sequence loads originating from at least one external unit (for example a storage magazine), via at least one forward one-way conveyor, and to provide said at least one preparation station with at least one outgoing conveyor, at least one sequence comprising charges in a desired order. The present invention can be applied to any type of preparation station, including but not limited to: - picking stations (also called "picking stations"), by taking samples from storage containers (also called "source loads"): an operator (or a robot) receives a list of samples (on paper, on the screen of a terminal, in voice form, in the form of a computer mission (in the case of the robot), etc. .) indicating to him, for each parcel to be shipped (also called "shipping container" or "target load"), the quantity of each type of product that he must collect in storage containers and group in the parcel to be despatched ; and - palletizing stations of storage containers (also called "source loads") themselves containing products: an operator (or a robot) receives a list of samples (on paper, on the screen of a terminal, in the form of in the form of a computer mission (in the case of the robot), etc.), indicating for each pallet to be shipped (also called "shipping container" or "target load"), the quantity of each type of container of storage (eg cartons) that it must collect and unload on the pallet to be shipped. 2. BACKGROUND OF THE INVENTION [0011] FIG. 1 shows a plan view of an exemplary known configuration for an automated parcel preparation storage system comprising: a storage magazine 7 comprising several (Two in this example) sets each formed an aisle 7a, 7a 'serving on both sides a storage shelf 7b, 7c, 7b', 7c 'with several levels of stacked storage. ; a set of conveyors bringing the source charges from the magazine 5 to the preparation stations, and vice versa. In the example of Figure 1, there are three subsets of conveyors, referenced 6, 8 and 9 respectively; several control preparation stations 10a to 10f, each occupied by an operator 1a and 1f extending perpendicularly to the conveyors of the third subassembly referenced 8; and 10 - a control system (also called "control unit"), which is a central management computer system responsible for controlling the entire automated storage system (storage warehouse, set of conveyors and control stations). preparation). The control system also manages the list of commands associated with each shipping container (target load) and therefore the order of the order lines forming this list, depending on the location of the storage containers (source loads) in the storage warehouse, the availability of the storage carts and elevators, and the product needs of the different shipping containers to be prepared at the preparation station. This is to optimize all travel and preparation times of the shipping containers and ensure synchronization between the arrival at the preparation station of a shipping container and storage containers ( containing the products indicated in the order list associated with this storage container). In the example of FIG. 1, each preparation station comprises two conveyor circuits: a first conveyor circuit for the storage containers, formed of two horizontal columns of conveyors: one (forward column 2) for the displacement storage containers from the third subset of conveyors 8 to the operator la, and the other (return column 3) for the reverse movement; and a second conveyor circuit for the shipping containers, formed of two horizontal conveyor columns: one (forward column 4) for moving the shipping containers from the third subset of 3031510 3 conveyors 8 up 'to the operator la, and the other (column back 5) for the reverse movement. In each of the first and second circuits, the forward column 2 and 4 (composed of horizontal conventional conveyors) performs the function of accumulating a predetermined quantity of containers upstream of the operator (or the automaton).
    [0003] A storage container carries out the following route: it is taken by a trolley in the storage magazine 7, then conveyed successively by the conveyors of the subsets 9, 6 and 8, then by the conveyors of the first column 2, for be presented to the operator. In the other direction (after presentation to the operator), the storage container carries out the reverse course: it is conveyed by the conveyors of the return column 3, then successively by the conveyors of the subassemblies 9, 6 and 8 and finally returned to the storage magazine 7 by a cart. As mentioned above, the storage containers (source loads) must be presented to the operator in a desired order forming a specific sequence. The same is true for shipping containers (target loads). In addition, the flow of storage containers must be synchronized with the flow of shipping containers. In order to relax the constraints on the storage magazine, it is assumed that the containers (storage containers or shipping containers) do not leave the storage magazine in the desired order (ie the order in which they must be presented to the operator). It is therefore necessary to carry out a sequencing operation of the containers between the storage magazine and the preparation station where the operator is located. In the example of FIG. 1, this sequencing operation is carried out by the second subset of conveyors 6 which itself acts as a buffer: the storage containers circulate in a loop and when the storage container expected on the conveyors of the column go 2 is presented in front of the latter (to complete the sequence of storage containers expected at the preparation station), it is transferred to the conveyors of the column go 2, the other storage containers continuing to flow over the second subset of conveyors 6. This process is performed for each of the storage containers expected in the sequence (i.e. in the desired order of arrival at the preparation station).
    [0004] In conventional manner, this order of arrival (sequence) is predetermined (that is to say determined, for each container, before this container reaches the preparation station) by the control system and, if necessary, recalculated during the routing of the containers from the output of the storage magazine to the preparation station where the operator is located (for example to account for a failure of a system element). In the example illustrated in FIG. 1, the return column for the shipping containers 5 is common to the preparation stations referenced 10a and 10b (these two adjacent stations are configured symmetrically with respect to one another, the common column forming an axis of symmetry). It is the same for adjacent preparation stations referenced 10c and 10d, as well as for those referenced 10e and 10f This aims to reduce the footprint of the preparation stations. Unfortunately, despite this trick, the current solution based on conventional horizontal conveyors (as described above in connection with FIG. 1) has several disadvantages. First, it has a high consumption of m2 at low running height (typically 750 mm). As an example of this footprint too high, the area required for six order picking stations (as in the example of Figure 1) is of the order of 100 m2.
    [0005] Another disadvantage is that the horizontal density of conventional horizontal conveyors included in the preparation stations is such that it makes maintenance access to these conveyors difficult (conveyor webs too dense). Another disadvantage is that, except to further increase the footprint of the preparation station (by increasing the length of the one-way column of each of the first and second circuits), it is not possible to increase the number of containers that can be accumulated upstream of the operator (or the PLC). Yet another disadvantage is that, in some configurations, the footprint of the preparation stations prevents or makes difficult maintenance access for trolleys (also called shuttles) used in the storage magazine. It is then sometimes necessary, for the maintenance of these trolleys, to access the storage magazine 3031510 5 from the rear, with a hoist system (referenced 11 in FIG. 1) which is not very ergonomic. Yet another disadvantage is that it is not possible to optimally deal with the case where it is desired to present the same container several times successively to the operator. Indeed, the subset of conveyors referenced 6 is currently used to carry out a reintroduction operation of the given storage container in the first column 2 of the first circuit of the preparation station (10a for example). This is not optimal because the time interval between two successive presentations of the same container to the operator can not be small and corresponds to the duration of travel by this container of the whole of the following circuit: conveyors of the column return 3, then those of the subset of conveyors referenced 6, and finally those of the column go 2. In practice, if this time interval is too high, it is out of the storage store two storage containers that contain the (same) type of desired products. The number of movements effected by the storage magazine is then increased, which is not a satisfactory solution (as this generally induces an increase in the number of aisles of the storage magazine, so as not to exceed a maximum capacity of 20,000. inputs / outputs can be made by the elevator or risers arranged at each end of an aisle). In order to overcome the aforementioned drawbacks of the conventional technique, a solution has been proposed in patent EP2487123A1 (Savoye). It consists of using at least one chimney in combination with at least one reciprocating elevator. The stack includes superimposed movable locations each capable of receiving and moving down at least one load (container). The chimney forms a means of vertical accumulation and sequential distribution of charges previously placed in the locations. The reciprocating elevator is able to move vertically along the chimney to each of its locations. For each given load that is presented, the control system reads its identifier, then selects one of the locations of the chimney (according to the identifier read and a predetermined sequence, defining the order in which the loads must come out of the chimney to be presented at the preparation station), and finally pilot the elevator to bring the given load into the selected location.
    [0006] The known solution of EP2487123A1, being based on a vertical accumulation of charges, has several advantages and makes it possible in particular to: - reduce the footprint of the picking station; to facilitate maintenance access to the elements included in the preparation station (no too dense conveyor web); - increase the number of charges that can be accumulated without negatively impacting the footprint of the preparation station; and - facilitate maintenance access for trolleys used in the warehouse.
    [0007] In addition, the combined use of a stack and an alternating elevator makes it possible to carry out a sequencing (that is to say a scheduling, in the sense of putting the loads in a desired order called sequence). It is recalled that the loads do not leave the storage magazine in the desired order and must be sequenced (scheduled) before being presented to the operator (or robot). The sequencing capability (scheduling) is related to the amount of charges that can be temporarily stored in the stack. The known solution of EP2487123A1 however has several disadvantages, in particular: it is limited in performance because it requires the use of one or more alternative elevators; - it is not multi-format at the level of the chimneys; and - it requires two separate equipment (elevator and chimney), used in combination, to create sequences, which increases its cost. 3. OBJECTIVES OF THE INVENTION The invention, in at least one embodiment, has the particular objective of overcoming these various disadvantages of the state of the art. More specifically, in at least one embodiment of the invention, one objective is to provide a technique (system and method) making it possible to overcome the disadvantages of the aforementioned conventional technique (see FIG. 1), while avoiding the disadvantages of the known technique of EP2487123A1. In a particular embodiment of the invention, there is provided a sequencing system for at least one preparation station, configured to sequence loads from at least one external unit, via at least one forward one-way conveyor, and supplying said at least one preparation station, via at least one exit 5-way conveyor, at least one sequence comprising loads in a desired order. The system comprises: - a controlled aerial lift with nacelles circulating in a closed loop, said paternoster, each nacelle for carrying at least one load; at least one buffer location configured to temporarily receive at least one load from the paternoster; and a control unit, configured to organize the movements of the loads in the system and to process each load arriving at the input of the paternoster, via said at least one input forward conveyor, according to one of the following modes, selected according to the the desired place for said load in said at least one sequence: (a) after introduction into the paternoster, the load undergoes a shortened transfer between two nacelles positioned face to face, then is presented to said at least one outward conveyor; (b) after introduction into the paternoster, the load undergoes at least one buffer transfer to a given buffer location, then is subsequently returned to the paternoster and finally presented to said minus an outbound conveyor; (c) after introduction into the paternoster, the load is transported without shortened transfer or buffer transfer, then presented to said at least one outward conveyor. The general principle is to perform a load sequencing (i.e., scheduling, in the sense of putting the loads in a desired sequence called sequence) using in combination, and according to an entirely new approach. and inventive (without reciprocating elevator), a paternoster (with at least one nacelle) and at least one buffer location, under the control of a control unit implementing three possible processing modes for each load which is presented at the input of paternoster.
    [0008] The mode (a) can be seen as a mechanism for accelerating (in the sense of moving up the current sequence, which is being modified to achieve the desired sequence) a given load which is paternoster entry, late compared to one or more other loads that have already presented paternoster input while they must be behind the given load in the desired sequence.
    [0009] Mode (b) can be seen as a mechanism for delaying (in the sense of rolling back in the current sequence, which is being modified to result in the desired sequence) a given load which occurs at the input of the paternoster in advance of one or more other charges which have not yet been presented to the paternoster entry when they must be in front of the given charge in the desired sequence. The mode (c) can be seen as a mechanism to neither accelerate nor delay (in the aforementioned senses) a given load that occurs at the input of the paternoster. The sequencing capacity (scheduling) of the present system is related to the amount of loads that can be temporarily stored in the paternoster (i.e., the number of nacelles of the paternoster) and the number of buffer locations. The proposed solution has many advantages, in particular but not exclusively: - minimizing sequencing constraints at the output of the external unit (for example, automatic magazine) by sequencing as close as possible to the preparation station; - reduction of the footprint; optimization of the size of the external unit (for example, automatic store) by pooling resources; - optimization of system performance; Optimizing the responsiveness of the system; - manipulation of multi-format loads if motorized roller nacelles are used; - cost optimization if the system includes several preparation positions (pooling paternoster and buffer locations); 30 - etc.
    [0010] According to one particular characteristic, in the mode b), the load undergoes, before or after the at least one buffer transfer, a shortened transfer between two nacelles of the paternoster positioned face to face. In this way, the load reaches the given buffer location more quickly and thus a nacelle location (useful for the sequencing of the other charges) is released more quickly. According to a particular characteristic, said at least one sequence belongs to the group comprising: sequences each comprising only source charges, each source charge being a product storage container; sequences each comprising only target charges, each target charge being a shipping container of product (s); and - sequences each comprising a target charge, which is a product shipping container (s), followed by at least one source charge, which is a product storage container (s). In a first particular implementation, each nacelle comprises N horizontally adjacent locations each having a rank between 1 and N, with N greater than or equal to two, and the system comprises: at least N input forward conveyors each configured to perform charge transfers to one of the N rank ranks, with a distinct rank rank being associated with each input forward conveyor; and - for each preparation station, N horizontally adjacent exit conveyors each configured to perform charge transfers from one of the N rank ranks, a separate rank rank being associated with each outbound conveyor . In one example, one or more of the forward conveyors can be shared between several preparation stations. In another example, the system includes a separate set of N forward conveyors for each preparation station. In this other example, the system therefore comprises, for each preparation station, N inlet conveyors (which enter the loads in the nacelle platform N) and N outgoing conveyors (which discharge the outgoing charges). N platform locations). In a second particular implementation, each nacelle comprises N horizontally adjacent locations each having a rank between 1 and 5 N, with N greater than or equal to two, and the system comprises at least one transfer table type device configured to perform transferring charges from said at least one inbound conveyor to any of the N ranks of locations. In this second particular implementation, each device of the transfer table type is used to pool an incoming conveyor between several rows of nacelle locations. According to a particular characteristic of this second implementation, said at least one transfer table device is common to at least two horizontally adjacent input gate conveyors and is configured to carry out charge transfers from any one of at least two Conveyors go inbound to any one of the N ranks. Thus, each device type transfer table is itself shared between at least two conveyors go input. In a third particular implementation (which can be combined with the second implementation), each nacelle comprises N horizontally adjacent locations each having a rank between 1 and N, with N greater than or equal to two, and the system comprises, at least for a given preparation station, at least one transfer table type device configured to carry out charge transfers from any one of the N rank rows to said at least one output forward conveyor configured to evacuate from the paternoster loads intended to to the given preparation station. In this third particular implementation, each device of the transfer table type makes it possible to pool an outbound conveyor between several ranks of nacelle locations. According to a particular feature of this third implementation, said at least one transfer table device is common to at least two horizontally adjacent output conveyors and is configured to perform load transfers from any one of the N Location ranks to any one of at least two outbound conveyors. Thus, each type of transfer table device is itself shared between at least two outgoing conveyors.
    [0011] In a fourth particular implementation, each nacelle comprises N horizontally adjacent locations and each having a rank between 1 and N, with N greater than or equal to two, and the system comprises: - N horizontally adjacent exit conveyors, each configured to receiving charges from one of the N rank ranks, with a separate rank rank being associated with each outward going conveyor; a common conveyor configured to receive loads from the N outgoing conveyors; - N final conveyors, each configured to receive loads from the common conveyor and bring them to one of the N preparation stations; 15 and the control unit is configured to organize the movements of the charges in the system as follows: * for each of the N ranks of nacelle location, sequencing of charges according to one of N sequences and providing sequenced charges to outbound conveyor associated with said nacelle location rank; 20 * transfer from the N conveyors go output to the common conveyor, charges forming the N sequences; for each of the N sequences, transfer from the common conveyor to one of the N final conveyors, loads forming said sequence. In this way, the paternoster and the N outgoing conveyors 25 (horizontally adjacent) are shared between several preparation stations. It will be noted that in the first and third implementations mentioned above, the paternoster is shared between several preparation stations. On the other hand, each preparation station is associated with a set of one or more exit conveyors which are specific to it and which are horizontally adjacent. Thus, each set of one or more outbound conveyors is disposed at a distinct vertical level, out of all the vertical output levels of the paternoster (i.e. all vertical positions at which the pods mark a stop for a charge output). In a fifth particular implementation, each nacelle comprises a single location, and the system includes at least one transfer table type device configured to perform load transfers from any one of at least two inbound forward conveyors horizontally. adjacent to the sole location of said nacelles. Thus, the paternoster is simpler (only one location per basket). Each transfer table type device makes it possible to use a plurality of horizontally adjacent entry way conveyors 10. In a sixth particular implementation (which can be combined with the fifth implementation), each nacelle comprises a single location, and the system comprises, at least for a given preparation station, at least one transfer table type device configured to carry out transfers. charging from the sole location of said nacelles to any one of at least two horizontally adjacent exit conveyors configured to evacuate paternoster loads for said given preparation station. Thus, each transfer table type device makes it possible to use several horizontally adjacent exit conveyors.
    [0012] According to one particular characteristic, the control unit is configured to process, in one of the following modes, each load presented, via an input return conveyor, at the input of the paternoster after having been processed by said at least one preparation station: (d) if the charge is still necessary, in a first time, to achieve the said at least one sequence: after introduction into the paternoster, the load undergoes at least one buffer transfer to a given buffer location, then is later returned to the paternoster and finally presented audit less a forward exit conveyor; (e) if the load is still necessary, in a second period less than the first delay, to carry out said at least one sequence: after introduction into the paternoster, the load is maintained there until it is presented to said at least one forward conveyor Release ; (F) if the load is still necessary, in a third period less than the second delay, to achieve the said at least one sequence: after introduction into the paternoster, the load undergoes a shortened transfer between two nacelles positioned face to face, then is presented to said at least one outbound conveyor; (G) If the load is no longer needed to perform the at least one sequence, the load is fed into the paternoster and then fed to the at least one return return conveyor. Thus, the system also makes it possible to optimally manage the return of the charges which appear at the input of the paternoster after having been processed by the item (s) of preparation. Modes (d), (e) and (f) allow retention as close as possible to the preparation station of a source load or a target load, in anticipation of subsequent use. This minimizes the input / output movements in the external unit (for example, automatic magazine). Mode (e) re-introduces a load (at the same or another picking station) more quickly than in (d) mode. Mode (f) is used to resend a load (at the same or other picking station) faster than mode (e). Mode (g) allows the return of charges in the external unit. According to a particular characteristic, in the mode (g), the load undergoes, after introduction into the paternoster, a shortened transfer between two nacelles positioned 20 face to face. In this way, a nacelle location is released more quickly. According to a particular characteristic, in the mode (d), the load undergoes, before or after the at least one buffer transfer, a shortened transfer between two nacelles positioned face to face.
    [0013] In this way, a nacelle location is released more quickly. In another embodiment of the invention, there is provided a method for sequencing charges from at least one external unit, via at least one forward one-way conveyor, and providing at least one preparation station, via at least one outgoing conveyor of at least one sequence comprising charges in a desired order, said method being implemented in a system comprising: a controlled aerial lift with nacelles circulating in a closed loop, said paternoster, each nacelle 3031510 14 for transporting at least one load; at least one buffer location, configured to temporarily receive at least one load from the paternoster; and a steering unit. The control unit organizes the movements of the loads in the system and treats each load presented at the input of the paternoster, via said at least one forward one-way conveyor, according to one of the modes (a), (b) and (c). ), selected according to the desired place for said load in said at least one sequence. In another embodiment of the invention there is provided a computer program product which comprises program code instructions for carrying out the aforesaid method, when said program is run on a computer. In another embodiment of the invention, there is provided a computer-readable and non-transitory storage medium storing a computer program comprising a set of computer-executable instructions for carrying out the aforesaid method. 5.

DETAILED DESCRIPTION In all the figures of this document, identical elements are designated by the same numerical reference. FIG. 2 (side view) and FIGS. 3A, 3B, 3C and 3D (sectional views along A-A ', B-B', CC 'and DD' respectively) illustrate a system according to a first embodiment of FIG. the invention, for sequencing source charges and target charges for supplying a type 1 preparation station for 1 (i.e., taking a product from a source charge (source container) and deposits in a target charge (target container)). In this first embodiment, the system is positioned between an external unit (not shown), for example an automatic storage magazine, and a preparation station 20 occupied by an operator 21. The system provides the preparation station 20 with on the one hand a sequence of source charges and on the other hand a sequence of target charges, each sequence respecting a desired order. The system comprises a paternoster 100, that is to say a controlled elevator equipped with a set of nacelles 110 circulating in a closed loop. Each nacelle 110 makes it possible to transport, in two horizontally adjacent locations (or positions) 111 and 3031510 16 112, two loads 30 (for example of the tray, cardboard, tray or other type) positioned next to one another. Each location 111 and 112 of the nacelle is for example equipped with a motorized conveyor section (or any transfer device) for transferring a load 30 on or off the nacelle. Alternatively, each location 111 and 112 of the nacelle is equipped with free rollers, the setting in motion is for example provided by a retractable mechanical means positioned at the end of each conveyor or buffer location. Other means of setting in motion can be envisaged.
    [0014] The pods 110 of the paternoster 100 circulate in step-by-step and closed-loop mode. They mark a piloted stop facing a set of vertical transfer positions. When a nacelle occupies one of these transfer positions, the system allows a load transfer between each location of the nacelle and equipment (conveyor or buffer location) facing this location of the nacelle.
    [0015] In addition, when two nacelles 110 are horizontally aligned, either or both of the loads can be transferred from one nacelle to the other, in order to quickly route the loads on the other side of the car. loop formed by the paternoster, in the manner of a shortcut (also called "bypass") and without having to wait for the rotation of the set.
    [0016] In the following paragraphs are presented different equipment (conveyor type or buffer location) included in the system and interfacing with the paternoster and its nacelles, when the latter mark a piloted stop vis-a-vis the aforementioned transfer positions. A first set of two in-feed conveyors 201 and 202 makes it possible to convey loads 30 to the input of the paternoster 100. For example, the one referenced 201 makes it possible to convey the source charges (ie typically loads containing the products to be sampled ) and that referenced 202 allows to route target loads (typically charges to contain orders to prepare). The reverse configuration is also possible (in this case the input forward conveyor 30 referenced 201 can route target loads while the forward conveyor 3031510 17 input referenced 202 can convey source loads). The conveyor referenced 201 interfaces with the location 111 of the nacelles and that referenced 202 interfaces with the location 112 of the nacelles. A second set of two outgoing conveyors 401 and 402 makes it possible to route and accumulate the loads 30 at the outlet of the paternoster 100 and to the preparation station 20. For example, the conveyor referenced 401 makes it possible to convey the source charges to be used in the preparation station 20; the conveyor referenced 402 can route the target loads to be used at the same preparation station. The reverse configuration is also possible.
    [0017] A third set of two return return conveyors 501 and 502 makes it possible to evacuate the loads 30 towards the paternoster 100, after treatment at the preparation station 20. For example, the conveyor referenced 501 makes it possible to evacuate the source charges and that referenced 502 makes it possible to evacuate the target charges. The reverse configuration is also possible.
    [0018] A fourth set of two exit return conveyors 301 and 302 is used to evacuate the loads 30 from the paternoster 100 to the external unit (not shown). For example, the referenced conveyor 301 makes it possible to evacuate the source charges and the conveyor referenced 302 makes it possible to evacuate the target charges. The reverse configuration is also possible. The referenced conveyor 301 interfaces with the location 111 of the nacelles and that referenced 302 interfaces with the location 112 of the nacelles. In addition, buffer locations 600, for temporarily storing the loads 30, are located vis-à-vis the stop positions of the nacelles (vertical transfer positions), on all or not levels. These 25 buffer locations are for example located outside the loop formed by the paternoster 100. Some buffer locations 600 are single depth, and allow to have two charges 30, two positions 601 and 602 one next to the 'other. Other buffer locations 600 can be multi-depth, especially double depth (with two positions before 601 and 602, and two rear positions 601 '30 and 602'). Each of the positions 601, 602, 601 'and 602' of a buffer location 600 is for example equipped with a device for transferring a load 30 to or out of said position, from or to a paternoster 100 nacelle. This device is for example a motorized conveyor section. For example, positions 601 and 601 'are for receiving source loads and positions 602, 602' for target loads. The system also comprises a control unit 40 which optimally organizes the movements of the loads in the system, and in particular on the paternoster, the conveyors and in the buffer locations, in order to make available on the outbound conveyor 401 of the source charges in a first sequence and on the outbound conveyor 402 of the target charges in a second sequence. For this purpose, the control unit 40 receives information (in particular a load identifier) read, on the loads passing at different places of the system, by reading devices (not shown), of the bar code reader type, reader RFID tag, etc. These places are for example located at the ends of the different conveyors. When a charge accumulated on one of the feed-in conveyors 201 or 202 is at the input of the paternoster 100, the control unit 40 determines the destination of the load as a function of the horizon of use or processing of this load. load at the preparation station 20.
    [0019] More specifically, the control unit is configured to process each input load of the paternoster, via one of the input forward conveyors, according to one of the modes (a), (b) and (c) detailed below. , selected according to the desired place for said load in said sequence. Mode (a) (or first go mode): after introduction into the paternoster 100, the load 30 undergoes a shortened transfer ("bypass") between two nacelles 110 positioned face to face, then is presented to one of the outgoing conveyors 401 (for a source load) or 402 (for a target load). Mode (a) is the mode to route an incoming load as quickly as possible to the preparation station. Indeed, thanks to the shortened transfer between two nacelles, this mode allows the load to quickly reach the opposite side of the paternoster. It is suitable for a load in front of, according to the sequence to be performed (i.e. the desired order of arrival at the preparation station), be presented in a very short term horizon. The shortened transfer makes it possible to modify the order of the charges to reach the desired order, since a charge benefiting from this shortened transfer will be presented to the preparation station before certain charges already present in the paternoster (charges present in pods located before (taking the direction of travel of the closed loop by the nacelles of the paternoster) the nacelle receiving the load during the shortened transfer). This mode (a) can be seen as a mechanism for accelerating a given load which occurs at the input of the paternoster, lagging behind one or more other loads which have already been presented to the input of the paternoster while they must be behind the given load in the desired sequence. Mode (b) (or second go mode): after introduction into the paternoster 100, the load 30 undergoes at least one transfer buffer to a given buffer location 600, then is later returned to the paternoster 100 and finally presented to one of the 15 conveyors 401 or 402 output. The realization of several buffers for the same load allows for example to bring it closer to the preparation station, while remaining in buffer (that is to say in the one of the buffer locations) and while building over the water the desired sequence. Optionally, the load undergoes, before or after the at least one buffer transfer, a shortened transfer 20 between two nacelles paternoster positioned face to face. Mode (b) is the mode to route an incoming load as quickly as possible to the preparation station. In fact, thanks to the buffer transfer (to a buffer location), this mode makes it possible to delay the moment when the load is going to be presented to the preparation station. It is suitable for a load in front of, according to the sequence to be performed (i.e. the desired order of arrival at the preparation station), to be presented in a relatively long time. The buffer transfer makes it possible to modify the order of the charges to reach the desired order, since a charge benefiting from this buffer transfer will be presented to the preparation station after certain charges not yet present in the paternoster. This mode (b) can be seen as a mechanism for delaying a given load which is present at the input of the paternoster ahead of one or more other loads which have not yet presented themselves at the input of the paternoster. whereas they must be in front of the given load in the desired sequence. In the mode (b), the control unit determines the level and position (front position 601 or 602, or back position 601 'or 602') of the buffer location 600, so as to arrange the order in which loads will be taken on a nacelle while minimizing the future movements of the paternoster. In the configuration where the buffer locations 600 are located outside the loop formed by the elevator 100, these locations being thereby managed in LIFO mode ("last in, first out" or "last in first out") , the control unit also manages the load accessibility constraint for subsequent setting in sequence. Mode (c) (or third forward mode): after introduction into the paternoster 100, the load 30 is transported "normally", that is to say without shortened transfer ("bypass") or transfer buffer, and then presented to One of the outgoing conveyors 401 or 402. The mode (c) can be seen as a mechanism for neither accelerating nor delaying (to the above senses) a given load which occurs at the input of the paternoster. This given load undergoes a "normal" transfer, in the sense that it enters the paternoster and comes out when the basket in which it was placed is facing one of the conveyors go out 401 (for a source charge) or 402 (for a target load), (having traveled a portion of the paternoster's closed loop.
    [0020] In the same way, after treatment (use) of a load 30 at the preparation station 20, the control unit conveys the loads that arise, via one of the return-entry conveyors 501 (for the source loads ) or 502 (for the target loads), at the input of the paternoster 100 and this according to the demands and needs remaining on these charges.
    [0021] More specifically, the control unit is configured to process each load (source load or target load) occurring at the input of the paternoster, via one of the input return conveyors 501 (for a source load) or 502 (for a load target), according to one of the modes (d), (e), (f) and (g) detailed below. Mode (d) (or first return mode): if the load 30 is still necessary (at another rank of the sequence), in a first time, to achieve the desired sequence, then after introduction into the paternoster, the load is undergoing at least one buffer transfer to a given buffer location, then is later returned to the paternoster and finally presented to one of the outgoing conveyors 401 (for a source load) or 402 (for a target load). Optionally, in the mode (d), the load undergoes, before or after the at least one buffer transfer, a shortened transfer between two nacelles positioned face to face. Mode (e) (or second return mode): if the load 30 is still necessary (at another rank of the sequence), in a second period less than the first delay, to achieve the desired sequence, then after introduction into the paternoster, the load is held there until it is presented to one of the outgoing conveyors 401 (for a source load) or 402 (for a target load). Optionally, in the mode (e), the load undergoes, before being presented to said at least one outward-going conveyor 401 or 402, a shortened transfer between two nacelles positioned face to face. Mode (f) (or third return mode): if the load 30 is still necessary (at another rank of the sequence), in a third period less than the second delay, to achieve the desired sequence, then after introduction into the paternoster , the load undergoes a shortened transfer between two nacelles positioned face to face, then is presented to one of the forward conveyors 401 output (for a source load) or 402 (for a target load). Mode (g) (or fourth return mode): if it is no longer needed to perform the desired sequence, the load is fed into the paternoster and then routed to one of the output return conveyors 301 (for a source load ) or 302 (for a target load) and finally to the external unit (storage magazine, for example). Optionally, in the mode (g), the load undergoes, after introduction into the paternoster, a shortened transfer between two pods positioned face to face.
    [0022] FIGS. 4A and 4B illustrate a first variant of the first embodiment of the invention, a variant in which the locations 111 and 112 of the nacelles are trivialized and can accommodate both source loads and target loads. It is also possible to put two charges of the same type on the locations 111 and 112 of the same nacelle 110 (either two source charges or two target charges).
    [0023] To do this, a transfer table type device 203, 204 makes it possible to direct a load 30 towards the location 111 or the location 112 of a nacelle, regardless of the conveyor from which it comes from (among the two conveyors go from entry 201 and 202). According to this principle, a load 30 on the inbound feed conveyor 201 may be directed to the location 111 or location 112 of a nacelle. Similarly, a load 30 on the inbound conveyor 202 may be directed to the location 112 or location 111 of a nacelle. In the same first variant, the implementation of a transfer table type device 403, 404 makes it possible to direct a load 30 towards the outward conveyor 401 or towards the outward conveyor 402 (for conveying to preparation station 20) and regardless of the location 111 or 112 of origin of the load on a nacelle. This first variant favors the optimization of the occupation of the nacelles, by making it possible to load two loads whatever their type (source or target). It also makes it possible to dynamically invert the allocation of outgoing conveyors 401 and 402 to the type of load, source or target. Thus depending on the configuration or more particularly in the case where the preparer is left-handed conveyor 401 may be assigned to the distribution of target loads and the conveyor 402 may be assigned to the distribution of the source charges; the opposite of the default configuration. For the forward path of a load, FIG. 4A illustrates the implementation of a transfer table type device 203, 204 common to the two inward feed conveyors 201 and 202, and in FIG. 4B, the implementation of a transfer table type device 403, 404 common to both outgoing conveyors 401 and 402. This principle 25 can be applied also for the return path of a load, with implementation of a transfer table type device (not shown) common to the two input return conveyors 501 and 502, and the implementation of a transfer table type device (not shown) common to the two output return conveyors 301 and 302 FIG. 5 illustrates a second variant of the first embodiment of the invention, in which variant the paternoster 100 makes it possible to feed two preparation stations 20 and 20 'situated at different heights. Each preparation station has its own outgoing conveyors 401, 402 or 401 ', 402' (horizontally adjacent to a given level) and its own return conveyors 501, 502 or 501 ', 502' (horizontally adjacent at another given level) 5 interfacing with the paternoster 100. FIG. 6 illustrates a third variant of the first embodiment of the invention, in which variant the preparation station 20 is equipped with a robotic device 22 making it possible to withdrawing a product in the source load (conveyed for example by the outgoing conveyor 401) and depositing it in the target load 10 (conveyed for example by the outward conveyor 402). A second embodiment of the invention is illustrated in Figure 2 in relation to Figures 7A, 7B, 7C and 7D (sectional views along A-A ', B-B', C-C 'and D-D' respectively). As in the first embodiment, the second embodiment makes it possible to sequence source charges and target charges to feed one or more preparation stations of type 1 for 1. These preparation stations can be manual, that is to say operated by a preparer, or robotic. On the other hand, and contrary to the first embodiment, this second embodiment implements a paternoster 100 with pods 110 at a single location 111.
    [0024] A single input one-way conveyor 201 carries source and target loads 30 to the input of the paternoster 100. It interfaces with the single location 111 of the nacelles 110. In a variant (not shown), a set of two inbound conveyors 201 and 202 can convey source and target loads 30, and a transfer table type device can direct each of these loads 30 to the single location 111 of a nacelle and what that is the conveyor of origin (among the two conveyors to go of entry 201 and 202). A single exit return conveyor 301 makes it possible to evacuate the source and target loads 30 at the outlet of the paternoster 100. It also interfaces with the single location 111 of the nacelles 110. In a variant (not shown), a device of the type The transfer table directs each of the loads exiting from the single slot 111 of a nacelle to any one of two exit return conveyors 301 and 302. A set of two outbound conveyors 401 and 402 allows the loads 30 to be routed and accumulated from the paternoster 100 and to the preparation station 20. For example, the outward conveyor 401 makes it possible to convey the source charges to be used at the preparation station 20, and the outbound conveyor 402 is used to route the target loads to be used at the same preparation station. The source and target charges are transferred from the nacelle 110 into the outbound conveyor 401. Through a transfer table device 701, the target charges are oriented on the outbound conveyor 402 while the source charges are not deviated. According to an equivalent principle, a set of two return return conveyors 501 and 502 makes it possible to evacuate the source and target charges 30 to the paternoster 100, after treatment at the preparation station 20. For example, the return return conveyor 15 501 makes it possible to evacuate the source charges and the return return conveyor 502 makes it possible to evacuate the target charges. Through a transfer table type device 702, the target loads from the input return conveyor 502 are reintroduced to the input return conveyor 501. Only the input return conveyor 501 interfaces with the input return conveyors 502. nacelles 110 of the paternoster 100.
    [0025] In addition, buffer locations 600, for temporarily storing the loads 30, are located vis-à-vis the stop positions of the nacelles (vertical transfer positions), on all or not levels. These buffer locations are for example located outside the loop formed by the paternoster 100. Some buffer locations 600 are single depth, and 25 allow to have a load 30, at a position 601. Other buffer locations 600 may be multi depth, especially double depth (with a front position 601 and a rear position 601 '). The main driving principles of the first embodiment (implemented by the control unit) apply to this second mode, while taking into account the particularities of the configuration related to the use of nacelles with a single location. .
    [0026] In a third embodiment of the invention, the system comprises a paternoster 100 with nacelles 110 at two locations 111 and 112, which allows only source charges to be sequenced (i.e. type of container: package, tray, carton, tray ...). The target loads are located and managed outside of this system. In other words, in this third mode and contrary to the first embodiment, the set of conveyors go (201, 202 and 401, 402) and return (301, 302 and 501, 502), as well as all buffer locations 600 are for managing the source loads. The principles described for the first embodiment of the invention apply to this third mode. It should be noted that in some cases of use, the source charge is taken as is, at the preparation station 20, to be deposited on or in a target load. As a result, the reintroduction of the source charge into the system is not necessary and the return conveyors (501, 502 and 301, 302) are not necessary. This case corresponds, for example, to the sequencing of packages (source charges) before palletizing. In other cases, an element of the source load is taken to be deposited on or in a target load. As a result, the reintroduction of the source charge must be managed via the return conveyors (501, 502 and 301, 302). This case corresponds for example to the sequencing of parcels arranged on trays; the trays being the 20 source charges. FIG. 8 shows a view from above of an exemplary implementation of this third embodiment of the invention as part of a palletizing station 20. The palletizing station 20 makes it possible to form one or more target loads. 12 (for example of the pallet, roll or equivalent type) from source charges 30 (for example of the package, pack, tray or other type). Depending on the case, the palletizing station can constitute either a target load (pallet) 12 at a time or several target loads simultaneously. The palletizing station 20 can be operated manually, be partially automated, be robotic, or be operated according to a different principle. In the example illustrated in FIG. 8, the palletizing station 20 is robotized and makes it possible to form several target loads 12 (in this case three pallets) from 3031510 sources 26 distributed sequentially to the preparation station. via the outgoing conveyors 401 and 402. FIG. 9 illustrates a fourth variant of the first embodiment of the invention, a variant in which a portion of the buffer locations 600 (denoted 5 600-a in FIG. 9) is located at the inside of the closed loop described by the circuit of the nacelles 110 and the other part of the buffer locations 600 (denoted 600-b) is situated outside this same loop, as well as the various conveyors (201, 202, 301, 302, 401, 402, 501, 502). The locations of the 600-a and 600-b portions can be single or multi-deep as needed.
    [0027] The principle of placing at least a portion of the buffer locations within the closed loop described by the nacelle circuit may be implemented regardless of the embodiment of the invention. A fourth embodiment of the invention is illustrated in FIG. 10, in which the system makes it possible to feed N preparation stations 20f, 202 and 203 (N = 3 in the illustrated example) with load sequences comprising each a target charge followed by one or more source charges (the source charges being sequenced or not between them). The paternoster 100 has n-shaped pods 110 at N locations 111, 112 and 113. The system comprises N forward conveyors 400, 401 and 402, horizontally adjacent and each configured to receive loads from the nacelles (the referenced output one-way conveyor 400 is associated with the nacelle location 111, that referenced 401 is associated with the nacelle location 112 and that referenced 402 is associated with the nacelle location 113). The system also includes a common conveyor 900, configured to receive loads from the N outbound conveyors 400, 401 and 402, and N final conveyors 400 ', 401' and 402 ', each configured to receive loads from the conveyor common 900 and bring them to one of the N preparation stations 20f, 202 and 203. The control unit 40 is configured to organize the movements of the loads 30 in the system as follows: - 3031510 27 - routing on each of the N conveyors go from output 400, 401 and 402 of charges in a separate sequence (there are N sequences in total). For example, the loads arriving on the conveyor 400, via the location 111 of successive nacelles, form a first sequence intended for the preparation station 201; the loads 5 arriving on the conveyor 401, via the location 112 of successive nacelles, form a second sequence intended for the preparation station 202; the loads arriving on the conveyor 402, via the location 113 of successive nacelles, form a third sequence intended for the preparation station 203; transfer from the N outgoing conveyors 400, 401 and 402 to the common conveyor 900, charges forming the N sequences; for each of the N sequences, transfer from the common conveyor 900 to one of the N end-to-end conveyors 400 ', 401' and 402 ', charges forming the sequence. For example, the charges forming the first sequence (for the preparation station 201) are transferred to the final forward conveyor 400 '; the charges forming the second sequence (for the preparation station 202) are transferred to the final conveyor 401 '; the charges forming the third sequence (for the preparation station 203) are transferred to the final conveyor 402 '. If the N end conveyors 400 ', 401' and 402 'are unmarked (i.e. each of them is not associated with a distinct location rank), each final 20-way conveyor can receive successive sequences that do not all come from the same outgoing conveyors 400, 401 and 402. Figure 11 shows an exemplary structure of the aforementioned control unit 40, according to a particular embodiment of the invention. The control unit 40 comprises a random access memory 43 (for example a RAM memory), a processing unit 42, equipped for example with a processor, and controlled by a computer program stored in a read-only memory 41 (for example: example a ROM or a hard disk). At initialization, the code instructions of the computer program are for example loaded into the RAM 43 before being executed by the processor of the processing unit 42. The processing unit 42 receives signals from input 44, processes them and generates output signals 45.
    [0028] The input signals 44 comprise various information relating to the operation of the system, in particular the load identifiers read (by bar code reader type reading devices, RFID tag readers, etc.) on the loads when they occur. pass to different parts of the system (for example at the ends of the 5 different conveyors). The output signals 45 comprise various control information for the control (control) of the equipment of the system (in particular the paternoster, the conveyors, the transfer table type devices and the buffer locations), in order to manage the movements of the loads in the system. system.
    [0029] Figure 11 illustrates only one particular implementation among several possible. Indeed, the control unit 40 is carried out indifferently on a reprogrammable calculation machine (a PC computer, a DSP processor or a microcontroller) executing a program comprising a sequence of instructions, or on a dedicated computing machine (for example a set of logic gates such as an FPGA or an ASIC, or any other hardware module). In the case where the control unit is located on a reprogrammable calculation machine, the corresponding program (that is to say the instruction sequence) can be stored in a removable storage medium (such as for example a floppy disk, CD-ROM or DVD-ROM) or not, this storage medium being partially or fully readable by a computer or a processor.
