[0001] The present invention relates to a method and an installation for filling successive egg trays on a line of moving egg trays. In its essential characteristics it relates more particularly to the operation that the tradesmen call 5 "de-ironing", which consists in completing the filling rate of the bins by identifying which egg receptor sites are empty of egg in the bin and inserting eggs that are available elsewhere. These eggs used to complete each of the current lockers in succession on the scrolling circuit may be made available in an egg supply disposed outside this circuit. They may also be taken from a specific rack in the chain that has been destined to be emptied of its eggs. It will be noted that at this stage the treated eggs are not identified other than as discrete objects which are distributed in compartments carrying them. It is only when one considers the preferred application conditions of implementation of the invention that the notion of eggs takes on a more precise meaning, by designating fragile objects which, like poultry eggs, require to be handled with care, properly stored in stable position in the racks that group them together. It is furthermore known that poultry eggs are processed in a very large number and at a high rate, which may justify the use of elaborate means which would not be economically useful in other applications. The invention is more particularly, although not exclusively, concerned with applications in which the stripping operations take place, in a more complete industrial process, after an earlier stage of state control of the individual eggs leading to extraction from each bin. eggs deemed invalid and unsuitable for the subsequent use of the eggs deemed valid remaining in each case. In egg-making machines, which are well-known machines and widely used in the poultry world, visiometry is used in particular to control the state of the eggs present in moving racks. In this way, it is sought to remove from the process eggs that are judged to be invalid, for example those eggs which are detected as not being fertilized or those having a defect in geometry.
[0002] These examination techniques, which relate to objects presented on examination in defined discrete locations, in a continuous scrolling, are for example used in the field of the food industry, especially for candling eggs of poultry, which consists of examining the eggs by transparency by exposing them individually to a light beam, most often in infrared light, in order to distinguish between the eggs according to a fertilization state of each, and of thus allow to select those which are fertilized, excluding those which are not, and that it is therefore useless to send to the destinations 10 reserved for fertilized eggs, such hatcheries where will be born chicks. Hence the interest of proceeding to a step of restoring to complete the filling rate of the bins before sending them to their subsequent destination. A high degree of compartment completeness is particularly desirable when the fertilized eggs are intended for use in facilities where they receive a product such as a vaccine administered to them by injection. It may be either to vaccinate the eggs or to use the individual eggs as a culture medium for the growth of a vaccine. It is important that traps passing through the egg-processing machine be complete, while containing only eggs judged valid, so as to prevent a dose of vaccine from being wasted or misused, since injection is carried out indifferently in each location of the rack, even in the holes that it comprises. We then know the establishment of a step of straightening, that is to say a step of filling the rack being processed by valid eggs that are taken elsewhere to complete the holes. A usual solution is to fill the crate by hand, an operator taking from time to time a locker on the conveyor to use the eggs it contains to fill other lockers scrolling. This operation can also be carried out by resorting to one or more robots which in turn take hold of an available egg to place it in the bin. But it is an expensive and generally not fast enough solution, especially if a lot of eggs have been removed from the bin in the mirage stage.
[0003] The present invention aims in this industrial context to provide a method of egg regrinding to ensure, without loss of time and with efficiency and reliability, the egg receptor locations of the different bins are properly filled. It also aims to ensure such a stripping by avoiding the use of equipment that would be complex, expensive, or difficult to install or maintain. According to the invention, an egg-grasping step is carried out from a reservoir formed of available egg-receiving cells which is arranged in parallel with the running path of the successive bins and inserted into the empty spaces of the bins. egg in each bin at the moment when it is opposite said tank, the tank being previously arranged according to a configuration information of the current rack so as to match the configuration of the tank in the presence or absence of a cell egg carrier with rack configuration in empty slots and full slots. The newly performed step of the invention thus identifies valid eggs and disposes them in a reserve available near the scrolling lockers that will be used to fill boxes left empty in the lockers kept online, the reserve formed by a plurality of cell lines being arranged in this new step depending on the rack being filled to optimize the seizure of the eggs from the reserve and the deposit of the eggs in the rack, these cells to be filled being themselves identified automatically. According to various features of the invention, the available egg reservoir is arranged automatically according to said configuration information of the rack being processed. The reservoir is arranged in the cell distribution before each entry, so as to take a configuration that can be said to be negative shape of the configuration of the current rack. The distribution of the egg-bearing cells 30 is complementary to the distribution of the empty locations in the case. The seizure is performed automatically by a transfer device so that the geographical distribution of the eggs seized in the reservoir corresponds to the geographical distribution of the empty locations in which the eggs seized by the transfer arm are to be inserted.
[0004] According to advantageous features of the invention, the transfer arm takes the form of a plate operating simultaneously on a whole rack, in particular of a suction pad, and the tank is arranged before each input stage during a step of displacement of the cells in the reservoir to ensure the presence of an egg in front of each of the suction cups of the transfer tray to be located opposite a cell left empty in the loading step of the rack being processed in the chilling station. Advantageously, the displacement of the eggs in the tank 10 prior to the capture step is row by row. And one proceeds row by row, alternately with a step of concentrating the eggs in which the eggs are tight against each other so as not to leave a free space between them, and at a step of spacing targeted eggs in which some of the eggs are spaced from their direct neighbor of the line to create at least one free location corresponding to a gripping area by the transfer arm. According to a particularly advantageous feature of the invention, it is possible in the process to supply the reservoir with valid eggs from time to time by means of all the eggs of one of the moving bins. This ensures that the reservoir has enough eggs to properly complete the successive bins in the scrolling circuit and this filling is performed using one of the bins, which is completely empty to be able to evacuate later. The reservoir is fed punctually when each line of the current bin has an egg count less than the number of available locations in the corresponding row of the tank. In the various cases mentioned, the information relating to the filling of the moving bins can be obtained by specific sensor means at the filling stage, placed on the bins or on the passage thereof, or be communicated by software means associated with the previous step, when the de-ironing step takes place between an earlier stage of checking the state of the eggs and extracting the eggs deemed invalid and a subsequent stage of vaccinating the eggs. According to one characteristic of the invention, the method further comprises a step of redistributing the eggs available in the reservoir by taking a determined number of eggs from the row of the most supplied reservoir to deposit the eggs thus taken from the reservoir. row of the tank less supplied. The invention also relates to an installation for implementing the method described above. This installation, in which a conveyor for running bins is able to have empty egg spaces, advantageously comprises a reservoir formed of rows of cells carrying egg available and disposed in the vicinity of the conveyor scrolling bins, means transfer device for entering valid eggs from said tank to the rack being processed, and control software means for determining configuration information to be given to the tank prior to input by said transfer means and means motorized drives for arranging the eggs of the tank in the determined configuration before each seizure. The transfer means may in particular consist of a suction pad, namely a tray comprising means for individually gripping the eggs, which are distributed in as many rows and columns as each of the successive trays comprises slots or cavities. receiving an egg. According to secondary features of the invention, the reservoir comprises cells for individual reception of the eggs which are grouped in distinct rows from each other, each formed of cells contiguous in series but individually movable along the corresponding row. The operation of the tank moving the cells is ensured from a software-based control device which manages the action of motorized drive means for selecting the cells to be moved and to drive them in rows by distributing the cells carrying the eggs available according to the predefined distribution in a gripping area of the reservoir from which the eggs present will be taken for transfer 30 in the bin to which they are intended. The drive means for moving and distributing the cells are advantageously made in the form of a comb with retractable teeth arranged along a drive line across the rows of cells. Such a comb will be described later as comprising a support arm capable of sliding in the direction defined by the rows of the reservoir and provided with movable fingers each between an extended position where it is active in driving a cell of the tank with which it is made to cooperate and a retracted position in which it is rendered inactive, in particular by the fact that it fades back from all the cells in front of which it passes when the comb travels all in a movement of va-and -from one end to the other of the tank. According to a particular embodiment of such a mobile cell reservoir, each cell housing forms a drive lug with which the comb teeth can engage by placing themselves either in front of or behind it, the choice being controlled automatically following the direction of movement of the comb so that the driven cell pushes with it the other cells that are contiguous with it on the same row. According to other features of the invention, the rows of available egg-receiving cells have a number of cells greater than the number of egg-receiving locations in each line of a rack. The reservoir may thus comprise a cell storage area distinct from the gripping zone for transferring the eggs. The installation may comprise, in addition to the first egg gripping arm ensuring the transfer of eggs between the reservoir and the current crate (the transfer tray), a second gripping arm of eggs, whose field of action is only centered on the tank. Such a local arm is advantageously used to collect eggs available in a row of cells richer in eggs and transfer them in a row less rich in eggs, in order to balance the filling rate of the cells between the different rows. The invention also relates to a tank suitable for carrying out the method as it can be described in the present application, and in particular a tank which comprises rows of cells that can be moved individually along a guide rail associated with each row by the action of motorized drive means controlled by a control unit with software means. The motorized drive means may comprise a support arm which extends across the guide rails and which is controlled in translation under the cavities of the reservoir, in a reciprocating movement along the rails between two positions of end, said arm carrying at least one carrier cylinder device at its end of a finger adapted to pass from a retracted position allowing the free movement of the support arm under the cells, to an extended position in which the finger comes into contact with one of the cells. In a particular embodiment, the reservoir further comprises a local transfer arm controlled by software means for seizing, after each transfer of eggs to the outside of the reservoir, a determined number of eggs in a row automatically determined to be the no longer provided the tank (the richest available eggs), and to arrange them in a row determined automatically as being the least supplied of the tank. The invention will now be more fully described in the context of preferred features and advantages, presented herein in one of these possible applications, with eggs, with reference to Figs. 1 to 9, in which: - Fig. 1 is a schematic representation of the settling installation, here arranged between a visiometry mirage station, at the exit of which the invalid eggs are removed, and a vaccine injection station in the eggs present in the bins; FIG. 2 is a detailed view of the tank of the installation illustrated in FIG. 1, in which two cells of the same row are partially represented and the associated motorized drive means, these guide means being illustrated with FIGS. fingers in the deployed position (the fingers disposed at the ends of the support arm) and fingers in the retracted position; FIG. 3 is a representative diagram of the sequence of steps of the stripping method according to the invention, in which process steps are represented by dashed lines when the installation is equipped with complementary transfer means, in a second embodiment of the installation; and FIGS. 4 to 9 are illustrations of the steps of the method according to the invention, with FIGS. 4 and 5 which illustrate the initial feed of the tank, FIGS. 6 and 7 which illustrate a classic case of filling a rack. by eggs of the tank, and Figures 8 and 9 which illustrate the tank feed conditions, Figure 8 being a case where the tank is not refueled while Figure 9 is the opposite a case where the tank will be powered. In an installation according to the invention such as that exemplified in FIG. 1, the essential station 1 is placed on the path of a conveyor 2, between an earlier treatment station for the eggs illustrated by a mirage station 4 and a post-processing station for the eggs illustrated by a vaccine injection station 6. The egg traps 8 are driven by the conveyor to scroll one after the other from the mirage station at the entrance of the station. and the exit of the latter to the injection station. The mirage station here comprises visiometry examination means 10 and gripping means 12 for removing from the rack past the examination means the eggs deemed invalid. The treatment station comprises, for its part, injection means 14 capable of penetrating into each egg individually, for example injection needles of a seed of vaccine present in number and disposition corresponding to that of the egg places in a rack, the assembly being carried by a remote control arm. The specific article of the invention will be described in more detail in that it comprises an egg tank 16, arranged in parallel with the conveyor and in which provision is made to make eggs valid for selective filling available. each of the bins successively admitted in the station of the roll, and a transfer arm 18, able to transfer eggs between the tank and the bins, and control software means 20 to control the movement of this arm as a function of information relating to the filling of the moving bins on the conveyor.
[0005] The conveyor is conventional and it consists for example of an endless conveyor belt, for the transport of lockers, the carpet successively serving the various positions of the installation. We are interested here in the part of the conveyor forming a running path between the mirage station and the treatment station.
[0006] Lockers 8 are arranged on the conveyor and they run from one station to another, preferably with the same frequency established between each passage. The bins have locations 22 for eggs, here arranged in checkerboard rows and orthogonal lines, with Xc lines of Yc locations. It will be understood that each trap arriving in the post-treatment station, following the mirage operation in which invalid eggs are identified and removed from the bin, may include a number of empty locations, in a given arrangement, so as to form a particular egg arrangement, different from the arrangement of previous and subsequent lockers. The reservoir 16 is arranged in parallel with the conveyor. It will be understood that this formulation specifies the fact that the reservoir is not arranged in line, and that it can then be oriented anyhow as soon as it is in the vicinity of the conveyor to allow the transfer of the eggs from the reservoir to a locker or vice versa. The reservoir is composed in particular of cells 24 which may each contain an egg, and motorized drive means 26 for moving these cells. The reservoir is composed of Xr rows of Yr alveoli, and the number of rows of the reservoir is defined as a number at least equal to the number of rows of the bin, and the number of cells per row as a number at least equal but preferably greater than the number of locations per line (for example at least a quarter of so-called additional cells). In the illustrated case, a number Xc of rows is advantageously chosen equal to the number Xr of rows, so as to easily match the nth line of the rack with the n-th row of the tank. This number is here arbitrarily equal to ten. Moreover, in the illustrated cases, it is chosen to have a reservoir consisting of approximately 33% more cells than there are egg slots in a rack, so that There are twenty cells per row in the tank, for only fifteen locations per line in each bin. As illustrated in Figure 2, the cells are carried by guide rails 28. Each row of the reservoir corresponds to a guide rail on which are mounted Yr alveoli of the row. Each cell 24, for example made of molded plastic, has a block shape, the lower end of which is extended by a tab 32 projecting vertically, perpendicular to the axis of the guide rail. The tab can extend over the entire width of the cell, as illustrated, but it is especially important that the cell housing has a decrease in section in the longitudinal direction, forming a shoulder at the rear and another at the front, so that when the cells are pressed longitudinally against each other, a clearance is formed between the cells to allow a finger to be inserted between them. The cell has in its upper part a hollow portion adapted to receive an egg, which projects sufficiently protruding from the cell when it is carried by it to be grasped by the gripping means dreueufs transfer tray associated with the tank. Motorized drive means 26 extend beneath these cavities. They comprise a jack device 34 for each row of cells, all of these devices being carried by an arm supporting them 36 which extends across the guide rails 28. This support arm is here borne at its lateral ends. by two belt drive means 38, so that the arm can move longitudinally under the rows of cells. The drive means are motorized so as to move in a reciprocating translation movement from one axial end to the other of the rows of cells. The support arm thus carries one or more devices with a cylinder, the actuation of which is controlled by the software means associated with the station. When the jack device is actuated in the direction of deployment, the cylinder rod 40 deploys to an extended position in which the free end of the rod, hereinafter called finger 42, extends to the lower end of the cells. The displacement of the support arm when a jack device is deployed generates the contact of the corresponding finger with a cell.
[0007] It is thus understood that when the motorized drive means move under the cells, the fingers of the jack devices do not touch the cells when the jack devices are in the retracted position, and if a jack device is in the extended position ( visible in Figure 2 for the cylinder device associated with the row on which cells have been shown), the corresponding finger pushes the cell against which it is in contact. As long as the finger remains in contact with the cell, the motorized drive means push this cell and all the cells located downstream on this row, which will also move along the rail; the upstream cells do not move.
[0008] When the cylinder device associated with a row is retracted, the finger is no longer across the protruding portions of the cells of this row and it no longer performs the drive function of these cells. These stop and retain the place that is theirs at the time of retraction of the cylinder device. It is understood that the cells are mounted on the guide rail with a particularly dimensioned slide connection, so that the cells can slide on their corresponding rail when they are pushed by the motorized drive means, but they can also be stop as soon as the jack device retracts and the corresponding finger stops pushing. For example, specific materials may be provided, which have a coefficient of friction allowing such a mechanical effect. As illustrated in FIGS. 6 to 9, two distinct zones can be distinguished in the reservoir, separated by a demarcation line 44 which extends virtually across the rows of the reservoir. A first zone consists of a storage zone 46, in which the cells are pushed against each other, and a second zone consists of a gripping zone 48, or transfer zone, in which the cells are arranged, row by row , not necessarily glued to each other, so as to form a negative mirror image of the rack admitted to the filling station on the conveyor, as will be described below. The reservoir is dimensioned so that each of these zones can extend in length over a distance equivalent to that of the Yc locations of the bin. According to the direction of travel of the rack, the gripping zone and the storage area are arranged on one side or the other of the demarcation line and the motorized drive means and the transfer means are calibrated as a function of this arrangement of the zones, it being understood that the transfer plate should grab the eggs in the gripping zone. In the illustrated examples, where the bins scroll from left to right, the gripping zone, the transfer zone, is located to the right of the demarcation line.
[0009] The egg transfer tray picks up all the eggs that are presented to it, whether in the transfer area of the tank, or in the bins, without any selectivity. It consists of a tray carrying gripping means, in number at least equal to the number of locations of each rack, and arranged identically to the arrangement of the locations of the rack, here in checkerboard. Here, the gripping means consist of suckers, all connected at the same time either to a vacuum pump that is actuated to grasp the eggs, or to compressed air that is circulated to release the eggs. These gripping means are in themselves known and will not be described in more detail here. It should be emphasized, however, that this type of suction pad is of interest, in the context of the implementation of the present invention, to be conventionally constituted in a form incorporating control means of the suction cups which act individually on each suction pad in opening or closing the grip function. In this case, the invention provides for managing the control of the suction cups from the tank configuration information as it is elaborated according to the configuration of the current rack to be filled taking into account the availability of the eggs. present in the tank at each bin filling cycle. The transfer arm (or platen) is associated with software control means 20, which determine in which direction the transfer of the eggs is to take place, that is to say if it has to seize eggs from the bin. treatment course to deposit them in the gripping area of the tank or if it must proceed in reverse, in transfer of eggs from the tank or the current rack. For this purpose, the software means receive information on the constitution of the running rack and on the number of eggs available in each row of the tank and deduce therefrom arm control instructions and motorized drive means for the arrangement of the gripping zone of the tank, prior to filling the rack as well as feeding the tank. The control software means 20, specific to the filling station, are connected to means for acquiring data relating to the filling of each of the successively admitted traps and / or software means 50 specific to the mirage station, and they are in further connected to the mechanical components of the filling station to control their operation, namely the transfer tray 18 and the motorized drive means of the reservoir 26. The invention will now be functionally described, relying on the diagram of FIG. 3 and the illustration of different steps in FIGS. 4 to 9, by reviewing the process steps according to which the filling of the rack or the tank is carried out, as a function of the number of eggs present in the current rack. and the number of eggs present in the tank, each time matching a line of receiving locations of the current bin with a row of cells present in the tank. As illustrated in FIGS. 4 to 9, the row C1 of the bin is filled or emptied with respect to the number of eggs present in row R1 of the tank and the nth line Cn is filled or emptied with respect to the number of eggs. present in the n-th row Rn of the tank. As illustrated in the diagram of FIG. 3, the software means 15 calculate the number of eggs to be taken from the reservoir to fill each bin, as well as the arrangement to be given to these eggs so that the transfer means can deposit The eggs are correctly located in each empty place, and furthermore, they determine when a supply of the tank may be punctually carried out by the eggs of a moving rack reaching the filling station. When a bin arrives in the filling station (action A1), at the exit of the machine to be fired, which precedes the filling station in the direction of movement of the bins on the conveyor, information 11 relating to the contents of this rack, that is to say, the presence or absence of eggs in each of the 25 locations, is transmitted to the software means by the software means specific to the machine to be drawn by which it has just proceeded to the removal of the invalid eggs from the rack according to the result of the mirage. It is understood that this information, sent to the control module associated with the installation, could also come from photocell or camera type sensors, specific to the installation and able to detect the filling information or not. bin locations. A first T1 test is performed by the software means on the basis of this information. If the rack is empty, nothing is implemented (A2 action) and the rack is discharged at the outlet of the filling station, so that it does not appear in front of the injection station. If the trap is not empty, the software means calculate (action A3) the number of eggs per line to complete to obtain a filling of the rack 5 meeting the specifications. A second test T2 is then performed on the basis of this calculation and on the basis of information held by the software means relating to the number of eggs present per row in the tank. If the tank has enough eggs per row to complete the corresponding lines of the current rack, respecting a previously determined completion threshold, one proceeds to a step El filling the actual bins. In this step E1, the software means analyze the arrangement of the bin on the basis of the information of the initially received content (action A4) and deduce therefrom a control instruction for the motorized drive means, so that that these arrange (action A5) the row of the reservoir so that the eggs present in the gripping zone of the reservoir form a negative image of the eggs present in the current bin, that is to say an opposite image in which each empty slot of the bin corresponds to a full cell of the tank, and vice versa. By way of example, reference is made to the case illustrated in FIGS. 4 and 5, in which the current rack has several empty slots among which a first location positioned in the first line and the seventh column, a second location positioned in the second line. and fourth column and third location positioned in second line and eighth column. The gripping zone of the reservoir is then arranged by the motorized drive means under control of the software means so that a first cell carrying an egg is disposed in the first row of the reservoir, at a distance from the line of demarcation equivalent to the congestion of seven locations, a second cell carrying an egg is disposed in the second row of the reservoir, at a distance from the demarcation line equivalent to the bulk of seven locations, and a third cell carrying a an egg is placed in the second row of the tank, at a distance from the demarcation line equivalent to the bulk of eight locations. It can further be seen that the motorized drive means do not move cells in the third row and leave them all in the storage area, since the current rack does not have an empty slot in its third row. line. Thus, the tank is configured according to the arrangement of the eggs in the current bin. The motorized drive means and their piloting by the software means will be described in greater detail below. This step of configuring the tank relative to the shape of the rack is completed and the filling is completed. The transfer tray then proceeds to the capture and transfer (action A6) of all the eggs arranged in the gripping zone of the reservoir to the bin. The disposition of the eggs at the time of their seizure in the gripping zone is preserved during the transfer, so that each seized egg is deposited in an empty location of the current crate, the arrangement of the eggs in the gripping zone before seizure by the transfer tray being a negative image of the bin. After the transfer, the motorized drive means associated with the reservoir are controlled by the software means (action A7) so that the eggs are pushed against each other, by row, in the storage area, each row of eggs being more or less pushed so that the rows have an alignment on the demarcation line between the storage area and the gripping area (made visible in Figures 6, 8 and 9). Insofar as the result of the second test T2 indicates that the reservoir does not have enough eggs per row to complete the corresponding lines of the current crate while respecting said completion threshold, a third test T3 is carried out by determining if the tank has enough empty cells, row by row, to accommodate all the eggs in the current bin. If the result is positive, that is to say that the reservoir has enough empty cells, row by row, to accommodate all the eggs present in the bin, it performs a step E2 of the tank supply, such as it will be described below. Such a case is illustrated in FIG. 9, in which there is shown a rack carrying 15 eggs on the first line and 12 eggs on the eighth row, and a tank with twenty empty cells on the first row and eighteen cells. empty on the eighth row, each row of the tank having at least as many empty cells as there are eggs present on the corresponding line of the current rack. On the other hand, if the result of the test T3 is negative, the step E1 of filling the box as described above is carried out again, admitting a degraded operation of the filling in which the completion threshold n ' is not reached. Such a case of negative test result is illustrated in FIG. 8, in which there is shown a rack carrying 14 eggs on the first line and 15 eggs on the fourth line, and a tank with sixteen empty cells on the first io row and fourteen empty cells on the fourth row. The fact that this fourth row of the tank has fewer empty cells than there are eggs present on the corresponding line of the current rack prevents the total transfer of eggs from the rack to the tank and makes the step impossible. power. It will be understood that the arrangement of the steps and tests as illustrated in FIG. 3 is intended to favor an optimal filling of the bins by the tank and to accept a degraded filling, that is to say with more bins left empty after filling than desired by the user, only when a point feed step of the tank can not take place. Thus, bin filling steps follow one after the other, as long as the tank does not have enough empty cells to accommodate all the eggs of the current rack. When this is the case, a step E2 for supplying the tank interrupts the succession of steps for filling the bins. The step E2 for feeding the reservoir is as follows. The software means calculate the position of the cells to give row by row for the reception of all the eggs of the current rack (Action A8). For the proper functioning of the tank in the operations of filling the future lockers, it is appropriate that no cell of a row, after feed of the tank by the eggs of a rack, be left empty upstream of a cell carrying an egg. The software means then perform a command instruction (Action A9) to space some of the cells of a row, as can be seen in FIG. 4, so that this empty space between two cells corresponds to an empty slot. 35 bin egg in progress.
[0010] As can be seen from FIG. 5, the arrangement of the eggs seized in the current bin by the transfer arm (action A10) is stored in the reservoir and the motorized drive means associated with the reservoir. are then implemented so that the contiguous cells are pushed against each other, by row, in the storage area, so as not to leave in this storage area an empty space of egg between two cells carrying the an egg. We will now detail the tank configuration operations relative to the shape of the current bin. This configuration takes place, as can be understood from reading the foregoing description, both before the filling of a rack and before feeding the tank by all the eggs of a rack. In the present detailed description, reference is made to the case illustrated in FIG. 7, in which the reservoir is configured so that the gripping zone forms a negative image of the treatment box being visible in FIGS. 6 and 7. software has determined in this case how it is appropriate to fill each row of the record, namely here for the first three lines, by an egg at the seventh location of the first line, an egg at the fourth location of the second line, and an egg at the eighth location of the second line. The drive means will push the cells of the tank row by row to configure the gripping zone as a negative of this image of the rack to be filled. The motorized drive means, piloted by the software means, will place in particular an egg on the first row at a distance from the line of demarcation equivalent to seven egg locations of a rack, an egg on the second row to a distance from the demarcation line equivalent to four egg locations in a bin, an egg on the second row at a distance from the dividing line equivalent to eight egg locations in a bin and no egg on the third row. The retractable finger (comb) support arm is axially displaced along the rows between a first end position, beyond the storage area, as shown in FIG. 6, and a second end position, beyond the gripping zone, as illustrated in FIG. 7. The jack devices are actuated independently of one another according to the arrangement to be given to each row with which they are associated. In the case illustrated, the jack devices associated with the first and second rows (comb teeth) are immediately actuated to push their row of cells, since eggs are to be taken from these rows, while the device cylinder associated with the third row is not actuated, since no egg should be taken in this row. The role of the drive means is to move the cells of the storage area to the gripping zone, arranged one row at a time, relative to the neighboring cell, either leaving one or more free locations or by squeezing the cells against each other. The motorized drive means performs a first training action which consists for each row to advance all the eggs by a distance corresponding to the number of eggs to be taken from this row, and to place these eggs in the gripping zone (called elsewhere transfer zone), by passing them the virtual line of demarcation. In the example described, an egg must be taken from the first row, so that the jack device is actuated in engagement with this cell the time of displacement of the motorized drive means 20 over a distance corresponding to the longitudinal space requirement. of an alveolus. All cells are pushed in series under the effect of the action of the finger against the cell at the head of the series, the farthest from the demarcation line, so that the alveolus has the row tail, the closer to the line of demarcation, passes it, the corresponding egg being found in the gripping zone. The jack device is then controlled so that the finger takes a retracted position, so that the cells of this row are no longer pushed and maintain their position. The jack device passes under the cells, carried by the support arm. It is understood that at the same time, the jack device associated with the third row is not actuated, since no egg must ultimately be taken in this third row, and the jack device associated with the second row was actuated to push the set of cells to a distance corresponding to the longitudinal size of two cells, since two eggs must ultimately be taken in this second row. Again, the cylinder device associated with the second row is controlled so that the finger takes a retracted position and can pass under the cells. We then proceed to a second training action, from the moment the support arm (comb) passes the virtual line of demarcation.
[0011] This second training action must allow to correctly arrange in the gripping zone eggs pushed out of the storage area during the first training action. The jack devices are operated according to the arrangement to be given to their associated row. The software means of the control device determine how far from the demarcation line the full cells must be placed to form the mirror image that it is desired to give to the gripping zone. They thus determine successive targets where to place these cells on the same row. The finger is placed in the deployed position to push the cell or cells to be placed in this row, and the finger is left in this deployed position until the cell against which it pushes is placed at the level of the first determined target, closest to the line of demarcation. To place the cell, the software means retract the finger of the jack device and, when the support arm has advanced a cell length, the finger is again driven in the deployed position and begins to push the cells until that the alveolus that it pushes directly takes place at the level of the next target. In the example described above, the cylinder device associated with the second row is actuated from the demarcation line so that the two cells selected to pass this line are pushed on a length equivalent to four cells, so that the cell driven directly by the finger of the jack device, namely the tail cell nearest the demarcation line before the second training action, take place on the first target corresponding to the previously determined position of an egg on the second row at a distance from the dividing line equivalent to four egg slots in a bin. The finger 30 is then retracted while the support arm continues to advance under the cells, and it is deployed just after passing the cell that it is desired to leave in place, so as to come into contact with the second cell, to place further on the second target. In this way, the retractable tooth comb 35, which together constitute the support arm and the control cylinder devices of their respective fingers, is cleverly piloted, so as to place each cell in the correct position in anticipation of their gripping by the plate of transfer. It is understood that these motions of the drive means are realized that one seeks to correctly place empty cells to receive the eggs of a rack in a step of feeding the tank, or that one seeks to place cells full to complete the successive egg traps. After the transfer operation, the comb having completed its race go to the end of the tank by carrying with it all the unnecessary cells which were, in each row of cells in series, in front of the last cell to have been left in place in the gripping area itself (the one on which the transfer tray operates), the retractable fingers are again actuated, but this time to engage with the socket in each row. The support arm is controlled to engage its movement in the return direction of its movement back and forth, and the fingers abut in the back of the drive lugs of the first cells encountered in the different rows, which are found all driven towards the other end of the tank, in front of a training line materialized then by the comb. The motorized drive means again pass through the reservoir from one end to the other, while the actuator devices are continuously actuated to push and store the cells, either empty or solid, against each other. previous operation. If a bin filling operation has preceded, the transfer zone has cells left empty and the motorized drive means push them against the solid cells remaining in the storage area, while ensuring (by controlling the withdrawal of fingers of the jack devices at the appropriate time) to leave the full cells in a configuration where each row has a full cell at the edge of the virtual line demarcation, as shown in Figure 6 for example. If a refueling operation of the reservoir has preceded, the motorized drive means push the cells to be found in the same configuration of Figure 6 where each row has a full cell at the edge of the virtual line of demarcation.
[0012] A second embodiment may be described with reference to Figure 3 and the elements of the flow chart added in dashed lines. It differs from the first embodiment mainly in that there is provided a second transfer arm, called "local", in addition to the first transfer arm described above (transfer tray) and able to move between the reservoir and the bin being processed in the chilling station. The local transfer arm has a field of action only centered on the reservoir, while the transfer tray flows from the tank to the bin and vice versa. The internal transfer arm to the reservoir allows each filling cycle, that is to say after each seizure of eggs of the reservoir by the first transfer arm, to equalize the number of eggs present in each row, by taking a determined number of eggs in a particularly large row to deposit them in a row that is not supplied. In this way, we offer a solution to the problem that may arise when the tank empties only on certain rows, while the others remain well filled. This can occur in particular when, and on average, the invalid eggs are equitably distributed over all the rows of the bin, a succession of pots containing little or no invalid eggs on a particular line succeeds one another. the filling station. However, as the machine is designed, the tank is filled by a rack in progress when all the rows of the tank can be supplied simultaneously. It is therefore sufficient that a row of the tank does not have enough empty cells for this supply to be impossible, and that only one row of cells continues to provide eggs for the replacement of the empty spaces in the corresponding line of the tank. locker. Meanwhile, the other rows of the tank, 25 empty, no longer allow to complete the lockers 100%. The second transfer arm (local transfer arm) receives an instruction from the software means associated with the filling station, which automatically determines the number of cells carrying an egg in each row of the tank and thus the identification of the row. 30 cells containing the most eggs (action A21). On the basis of this data, the software means indicate in which row of cells the second transfer arm must enter eggs and the number of eggs it must enter (action A22). At the same time, the software means locate the row of cells containing the least number of eggs (action A23). They then send a control command to the motorized drive means to arrange (action A24) this row so as to properly present a number of empty cells sufficient to receive these eggs. The software means finally indicate to the transfer arm in which row of cells these eggs must be deposited (action A25).
[0013] For example, the local transfer arm can, at each cycle, recover three eggs from the fullest row of the tank and deposit them in the row less filled. It is understood that the choice of three eggs is purely arbitrary, and that it may not be the same after each cycle, the second transfer arm then being arranged so that it can indifferently enter one or more eggs according to the instructions of the software means. The modification of the number of eggs in two rows of the reservoir resulting from this action of the second transfer means is followed by a control of the motorized drive means to adjust if necessary the position of the full cells and the empty cells of these two rows, with respect to the virtual line of demarcation between the gripping zone and the storage area, such that this position sought after each filling cycle could be described before. The foregoing description clearly explains how the invention achieves the goals it has set for itself. In particular, it allows the establishment of egg-making operations which are particularly effective, in that they allow a filling rate successive successive optimal. In the case of the first embodiment, namely that where only the main transfer arm is provided (the plate which takes the eggs prepared in the cells of the tank and deposits them in the current bin), without the contribution of the second arm ensuring a transfer of local eggs, it will be within the reach of tradespeople to determine at best how much additional cells to provide. Increasing the number of cells in the tank relative to the number of eggs in the bins improves the final filling rate, but with the side effect of increasing the average time spent by the eggs in the tank, and therefore out of the incubators.
[0014] In an alternative embodiment of the invention not specifically illustrated in the drawings, it will be possible to modify the de-ironing station so as to adapt it to the treatment of poultry egg traps respecting a distribution of the receiving locations of staggered eggs rather than a simple checkerboard distribution in rows and rows in two orthogonal directions to each other. An appropriate solution for this purpose consists in equipping the means for transferring the eggs between the tank and the bin in the course of a mechanism capable of transforming the rectangular arrangement of the tank into a staggered arrangement by staggering the cells by half a step. punctually whenever it is necessary. Performing this operation at the level of the egg transfer device makes it possible to best satisfy a staggered arrangement from the point of view of the structure of the equipment and the operational safety. It follows from the foregoing that the invention is not limited to the embodiments which have been specifically described nor to the actual embodiments which have been shown in the figures. On the contrary, it extends to any variant passing through equivalent means. Thus, there are situations where it will be possible to overcome the presence of egg receiving cells concretized physically in their mobility on rails provided for this purpose in the tank. Assuming, for example, that while remaining in the world of the food industry, the objects contained eggs stored in individual cells in the bins are no longer poultry eggs with their severe handling requirements but fruit siding freely side- side-by-side, one behind the other on each column of the rack, it is possible to use a reservoir comprising a set of retractable fingers individually controlled between ejected position and retracted position when necessary to enter the objects available on each row in a number corresponding to the number of missing objects in the corresponding reservoir column, pushing them to bring them into position to be collectively grasped by the transfer device and to be deposited by this device in the place left free in each column at the back of the current locker. The invention is no more limited to an implementation integrating the stripping station with its reservoir and its associated piloting device in a production line involving an egg candling station in the previous treatment step and / or a Vaccine injection station in a subsequent step, that the operations specific to each of these steps are carried out in continuity with the de-ironing step, respectively before and after it in the same industrial installation, or that compared to the step, they are deferred in time and / or implemented in geographically remote sites. While it is true that, in the case of egg trays when they are admitted to the processing operations, insufficiently filled egg trays most often come after previous treatment by non-destructive testing of the condition of the eggs. individual visiometry and leading to extract from each trap eggs deemed invalid by an automatic analysis of the information collected by visiometry, it is just as accurate at the exit of the station of the chiller, the lockers whose filling has been completed may be for many subsequent treatments other than vaccine injection. As an alternative to the injection of a true egg treatment vaccine, one will first consider the injection of a viral seed in applications using fertilized eggs as a culture medium for the production of vaccine, as well as the injection into eggs of a dangerous or expensive drug other than a vaccine or any treatment product to protect the chicks that will be born from treated eggs. Treatments of poultry eggs by taking a sample of the material internal to each egg by means of a needle piercing the shell are other examples of applications where also the industrial requirements are particularly severe both in terms of filling completeness of each trap and the precision of the arrangement of the different egg locations in each bin and geometric regularity from one location to another in terms of the shape of the individual eggs and the arrangement of the eggs. different eggs in their respective receiving locations.
