    [0001] DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to the general field of product conveying, and in particular to a particular device and method for positioning the products, that is to say at least to modify the product. orientation perpendicular to the conveying plane.
    [0002] Some products of the bottle type have flattened faces at their sidewall, in particular for affixing a label presenting information on their contents. Such bottles, or products, and have a main axis that is vertical when the products are positioned upright on a flat support. They may also have a section of oblong shape in the conveying plane. Depending on the way in which these products are positioned, one can thus be able to read, or not, said information that is on their flattened faces. Their orientation on display stands is therefore important for traders and consumers. The orientation of the products once in boxes is also an important factor for optimizing the volume of said boxes. There are known facilities for making displays of such products, wherein the products are aligned one behind the other, forming one or more rows. In order for the products to be all properly oriented, product orientation devices have been implemented in the plants to rotate the products about an axis perpendicular to the conveying plane, namely a vertical axis. Document FR 2 285 303 thus describes an installation equipped with a device for orienting the products. The installation comprises an endless conveyor on which said products are aligned one behind the other, the endless conveyor having a direction of supply and a direction of supply of said products. The installation is equipped in particular with an endless screw allowing the product to be pitched and a given orientation 30. The orientation that the products take in the screw may or may not conform to the desired orientation. Also, downstream of the worm, there is provided an orientation device which ensures the pivoting of the product to 180 degrees. Such an installation has certain drawbacks among which may be mentioned the following: -2- - the screw used to orient the products and to put them in step has dimensions adapted to the products. Also, when the types of products processed change shapes or dimensions, it is necessary to change the screws. However, a change of screw requires to immobilize the installation, which affects the overall productivity of the installation. In some applications, it may be necessary to provide an alternative solution to the screws; - In addition, it is necessary to provide a storage area near the installation for storing the worm adapted to different products to steer. The overall installation can thus be excessively cumbersome; - The installation with several screws can be expensive, because it is necessary to provide several different screws; - Lastly, the static orientation downstream of a screw may destabilize or mark the products and therefore does not operate at high speed. In general, the object of the invention is to propose a technical alternative that makes it possible to orient the products, that is to say to rotate them on the conveyor, from any angle, so that the 20 products are oriented differently before and after the implementation of the invention. The invention also aims to provide an alternative to the use of the worm, to overcome the aforementioned drawbacks. For this purpose the invention proposes to achieve the orientation of the products by manipulating each product separately, using an actuator 25 dedicated to said product and moving transversely to the conveying direction. The invention thus relates to a positioning device for positioning products simultaneously to their conveying one behind the other in a conveying plane and along a conveying direction. This device is characterized in that it comprises at least one orientation means, itself comprising at least one movable pusher along an action movement between an inactive position and an active position, said action movement having the effect of acting on a product by pushing it to rotate it by a predetermined angle around an axis perpendicular to the conveying plane, the at least one pusher being movable also in the conveying direction. The invention also relates to a method for positioning products simultaneously at their conveying one behind the other in a conveying plane and along a conveying direction, comprising an orientation step, during which the products are turned around an axis perpendicular to the conveying plane. This method is characterized in that said orienting step is performed by moving at least one pusher along an action movement, between an inactive position and an active position, said action movement having the effect of acting on a product by pushing it to rotate it by a predetermined angle about an axis perpendicular to the conveying plane, said action movement being in particular parallel to the conveying plane and perpendicular to the conveying direction. The invention will be better understood thanks to the description below, which is based on possible embodiments, explained in an illustrative and non-limiting manner, with reference to the following appended figures: FIG. 1 shows a view from above, in the conveying plane, a device in two different states, namely either before or after the paging; FIG. 2 illustrates a device in which the products are oriented by means of independent pushers actuated by the same jack on each side, FIG. 2a illustrating the situation before the orientation, FIG. 2b the situation during the orientation, and FIG. 2nd the situation after grouping; - Figure 3 shows an embodiment where the products are oriented and grouped with independent pushers; FIG. 4 compares the positioning of the orientation means according to a referencing scheme and the products, to explain the concept of product most in advance or late; - Figure 5 finally shows two products of oblong section on a conveyor, the product at the top having its longest length in the conveying direction, the bottom product having its long length transverse to the conveying direction. The invention thus relates to a positioning device 1 for positioning products 2 simultaneously to their conveying one behind the other in a conveying plane 3 and along a conveying direction 4. The products 2 can spaced apart from each other more or less regularly. They are generally arranged one behind the other longitudinally, that is to say in the conveying direction 4.
    [0003] The products 2 generally have a particular shape illustrated in FIG. 5: the shape of the products is not a shape resulting from a symmetry of revolution about a vertical axis. The products 2 are then flasks or others having an oblong shape, that is to say a longer than wide shape.
    [0004] According to the invention, the positioning device 1 comprises at least one orientation means 5, itself comprising at least one pusher 6 movable along an action movement between an inactive position and an active position, said movement acting to act on a product 2 by pushing it to rotate it by a predetermined angle about an axis perpendicular to the conveying plane 3, the at least one pusher 6 being movable also in the direction of 4. The orientation means 5 thus alone ensures the orientation of the product 2. The pushers 6 can be mounted in carriages 7, and this fixedly or longitudinally movable. Thus, in particular embodiments, the at least one pusher 6 is mounted fixed in the conveying direction 4 in a carriage 7, itself movable in the conveying direction 4. In other embodiments, the less a pusher 6 is movably mounted in the conveying direction 4 in a carriage 7, itself also movable in the conveying direction 4.
    [0005] Alternatively, the pushers 6 can be mounted directly mobile on the frame. In these cases, the pusher 6 is mounted movably along the conveying direction 4 on a fixed slide 8, illustrated in FIG. 3. According to an additional possible feature, the at least one orientation means 5 comprises a pair of pushers 6 similar and 30 placed vis-à-vis one another, so as to act together on the same product 2, which allows a symmetrical action on the product 2. The devices according to the invention can be made to treat asymmetrical products 2, as shown in Figure 5. The length of such a product 2, measured in the conveying direction 4, then changes 35 according to its orientation and the action of the pushers 6 can then be impossible after a first rotation if they can not tighten against the product 2. Thus, in advantageous embodiments, the distance between the two pushers 6 of the pair of the at least one orientation means 5 is adjustable in the direction of conveying 4, thanks to a mobility in said direction of at least one of the two pushers 6, so as to compensate for the variation in size of the product 2 following its orientation by pivoting about an axis perpendicular to the conveying plane 3 It will be appreciated that it is advantageous for the device to be able to process several products 2 at each cycle. It is then provided with several orientation means 5, aligned one after the other in the conveying direction 4. Each orientation means 5 thus comprises two pushers 6 and they are then distributed one after the other, a half of them being arranged on one side of the product line 2, the other half being arranged on the other side. The pushers 6 side by side can then be governed by the action of a single actuator, or be governed by each their actuator. Thus, in particular embodiments, the positioning device 1 comprises at least one pair of orientation means 5, mounted side by side in the conveying direction 4, the pushers 6 side by side being driven by the same actuator. In other embodiments, the positioning device 1 comprises at least two orientation means 5 mounted side by side in the conveying direction 4, the pushers 6 side by side being driven by independently controllable actuators. The relative positioning of the orientation means 5, or their sequence of actuation must be adapted or adapted to the position of the products 2 on the conveyor 10. In fact, the products 2 arrive one after the other, with a spacing more or less repeatable, in a certain precision range. In extreme cases, the products can be spaced completely randomly, without a form of repetition being identified. It is therefore necessary to identify the position of the products 2 and their mutual spacing before guiding them.
    [0006] Thus, according to a possible additional feature, the positioning device 1 comprises a detection cell 9, mounted upstream of the at least one orientation means 5 in the conveying direction 4, for unitarily detecting each product 2 to be oriented, as well as a control unit for receiving the signal from said cell 9 and conditioning the operation of the device. The subject of the invention is also a method implementing the device which has just been described, namely a method for positioning products 2 simultaneously with their conveying one behind the other in a conveying plane 3 and along a conveying direction 4, comprising an orientation step, during which the products 2 are turned about an axis perpendicular to the conveying plane 3.
    [0007] This method is characterized in that said orienting step is performed by moving at least one pusher 6 along an action movement, between an inactive position and an active position, said action movement having the effect of acting on a product 2 by pushing it to rotate it by a predetermined angle around an axis perpendicular to the conveying plane 3, said action movement being in particular parallel to the conveying plane 3 and perpendicular to the conveying direction 4. This movement allows to obtain directly the desired orientation of the products 2, without the need to use a screw, for example. In advantageous embodiments, the method comprises, in addition, a step of longitudinal positioning of the products 2, in the conveying direction 4, so as to position them relative to each other at a predefined distance, such as for example by group , or at a similar and regular distance from each other, namely for a setting. This longitudinal positioning step is notably implemented by moving the push-button (s) 6, in the conveying direction 4, of the intermediate push-buttons 6 which can also return to the inactive position, leaving the end pushers 6 in the active position delimiting a group. of products 2 in contact with each other. Said intermediate pushers 6 can also return between the products in contact to stabilize them. In some embodiments, the push-buttons 6 are all positioned in the same way that the products 2 are positioned on the conveyor 10, thanks to a detection cell 9, and they are all actuated at the same time in the active position. The actuation of the pushers 6 in the active position ensures the pivoting of the products 2 around an axis 30 perpendicular to the conveying plane 3. In the active position, after pivoting of the products 2, the pushers 6 formed by fingers are thus positioned between the products 2 oriented, so that said fingers can be used in the same way as elements of a grouping means: by moving the pushers 6 longitudinally, the fingers are moved and push the products 2, creating spaces and In some embodiments, the fingers are in the form of a bent piece. The device is thus advantageously provided with a cell 9 placed upstream of the orientation means 5, as well as a module for measuring the position of the products 2 on the conveyor 10. The module optionally communicates with a device for controlling the longitudinal displacement of the orientation means 5, so that they position themselves according to the same distribution scheme as the products 2 on the conveyor 10. When all the randomly spaced products arrive at the level of the orientation means 5 all pairs of pushers 6 are actuated at the same time in the active position, so that the products 2 are oriented at the same time by pivoting for example at an angle of 90 °. Thus, in some embodiments, the position of the successive products 2 is detected upstream of the orientation step, the method comprising a step consisting essentially of correspondingly positioning in the conveying direction 4 a plurality of pushers 6. lying side by side, and before they are actuated between their inactive position and their active position. According to an additional possible characteristic, the orientation step is carried out when the product 2 arrives in a predefined fixed zone, that is to say an immobile zone relative to the frame on which the conveyor 10 passes. a product 2 is in such a predefined zone, whether its presence has been detected or calculated following the upstream detection, the corresponding orientation means 5 is actuated. In other embodiments of the method, it comprises a step of positioning a carriage 7, comprising several pushers 6 next to each other in the conveying direction 4, in a position such that a first pushbutton 6 is facing a product 2 to be orientated, in particular the most advanced or the latest in accordance with a referencing scheme, the carriage 7 then being moved in the conveying direction 4 and the at least one other pusher 6 actuated when it is in relation to another product 2. Finally, in particular embodiments, the method comprises a step of shifting the products 2 transversely to the conveying direction 4 under the effect of the action of the at least one pusher 6. For example, alternatively, after grouping the products 2 or setting the step, the pushers 6 of a carriage 7 are again advanced transversely, while the pushers 6 in vis-à-vis the other carriage 7 are moved back by being moved transversely the same distance. By alternating the additional advancement movement pushers 6 of a carriage 7 for a first group, and the other carriage for the next group, we obtain groups of products 2 reoriented located on one side and then the other of a central line of the conveyor 10. Thus, the products 2 can be oriented, and optionally grouped, at the same time as they are moved by the conveyor 10. The method can therefore be carried out as follows. The endless conveyor 10 is moved at a constant speed, called feed speed, Va. To orient the products 2, the carriages 7 are also moved at a first speed V1 which is substantially identical to the forward speed Va of the conveyor, at least for positioning a product 2 in front of an orientation means 5. The products are oriented in the following way: firstly, at least one product 2 is positioned in front of an orientation means 5, the push-buttons 6 move from the inactive position to the active position, which causes the orientation of the product 2 by pivoting about an axis perpendicular to the conveying plane 3, - then, the pair of pushers 6 goes from its active position to its inactive position, to release the product 2 oriented. Since the pivoting is done simultaneously with the carriage 7 advancing at a speed V1, when the products 2 are oriented and released, the carriage 7 is downstream from its initial position. Also, after release of the products 2 oriented, the carriage 7 is moved in the opposite direction of the supply direction of the products 2, at a second speed V2 which is greater than the speed V1, so as to allow the alignment of the first product 2 the line opposite the first orientation means 5, at the initial position of the carriage 7. In the case of an installation where the orientation means 5 ensure the displacement of the product groups 2 oriented up to a set point, that is to say a downstream station of the installation where the group is entered to be cashed, for example, the orientation means 5 are moved 35 to the point of capture at a speed V3 , higher than the speed V1, or the feed rate Va of the products. Then, the device releases the product group 2 at the set point and returns to the initial position with a velocity movement V2. In a large number of embodiments, such as those illustrated in FIGS. 1 to 3, the positioning device 1 is capable of treating several products 2 each time and is thus provided with several orientation means 5, each processing a product 2. These orientation means 5 are mounted side by side in the conveying direction 4, and are each intended to act on a different product 2 driven by the conveyor 10.
    [0008] The rotation of a product 2 can thus be obtained by the action of a single pusher 6, as long as a stop is arranged in facing relation, slightly offset to obtain the desired effect. In these cases, the orientation means 5 therefore comprises only one pusher 6, and an abutment vis-à-vis, shifted sufficiently to create a rotation.
    [0009] Preferably, the pivoting movement of a product 2 about an axis perpendicular to the conveying plane 3 is however obtained under the effect of two movable pushers 6 mounted one vis-à-vis the other. The orientation means 5 then comprises a pair of pushers 6 which are slightly offset in the conveying direction 4, so that they each act on one side of the product 2 to create the expected pivoting movement. Two pushers 6 thus opposite then create parallel forces, of opposite directions, preferably parallel to the conveying plane 3 and perpendicular to the conveying direction 4, which may have the effect of rotating the product 2 about an axis perpendicular to the plane of 3. Such an embodiment allows, during the action of the pushers 6, not to shift the product 2 transversely to the conveying direction 4. In some cases, the two pushers 6 can then be actuated when the product 2 is located in a symmetrical position relative to an axis located equidistant from the directions of action of the pushers 6, the latter having actions of amplitude and force preferably similar. In general, that the action on a product 2 is done with a pusher 6 or more, the principle is to act on the product 2 by creating at least two forces whose directions are not superimposed and which, together, cause a movement comprising a rotation about an axis perpendicular to the conveying plane 3. This allows to exert a driving force on the product 2, with at least one component - 10 - parallel to the conveying plane 3 while it rests against an offset stop, fixed or mobile itself. In advantageous embodiments because of their simplicity, each orientation means 5 comprises a pair of pushers 6 intended to act, each on one side of the product 2, along a translation movement perpendicular to the conveying direction 4 and parallel to the conveying plane 3. As the action of the pusher 6 on the product 2 requires a certain time, the pusher 6 must be able to be moved in the conveying direction 4, to follow the displacement that the product 2 undergoes during the duration the action of the pusher 6 and thus avoid that it forms an obstacle that may drop the product 2 or deform. This freedom of movement in the conveying direction 4 can be arranged in different ways. In possible embodiments, the longitudinal mobility of the pusher 6 is provided by a carriage 7 in which the pusher 6 is mounted. This carriage 7 is, in turn, mounted with a longitudinal movement capacity so as to be able to move substantially at the same speed as the conveyor 10. The carriage 7 is thus mounted on a fixed slide. Of course, the positioning device 1 then preferably comprises two such carriages 7, the column of products 2 flowing between them. In the preferred cases where each product 2 is pivoted by the action of a pair of pushers 6, the set of pushers 6 is distributed, for one half, on one of the two carriages 7, and for the other half, on the other carriage 7. The products 2 are therefore rotated in each case by a pair of pushers 6, each of them being mounted in one of the carriages 7. Such an assembly can be adapted by providing that the pushers 6 are movably mounted in the carriages 7 parallel to the conveying direction 4. The longitudinal mobility of the pushers 6 is then ensured, on the one hand, by the mobility of the carriages 7 on which they are mounted, and, on the other hand, Moreover, by the mobility of their mounting on these carriages 7. One of the advantages of such an assembly compared to the previous one is, as will be described further below, to be able, on the one hand, to move the carriages 7 essentially to the same speed as the conveyor 10, and, on the other hand, of placing the pushers 6 to perform a grouping function, setting or not, or any other predetermined longitudinal positioning function of the products 2. The settings of the two functions can then be independent. In the two cases just described, the carriages 7 can form a single mobile structure.
    [0010] In another type of embodiment, the pushers 6 are each mounted on a longitudinal slide 8 fixed to the frame. Unlike previous assemblies where the pushers 6 are mounted in carriages 7 whose movement allows to possibly follow the advance of the products 2, only the setting in motion of the pushers 6 here makes it possible to avoid creating a stop for the Advantage of the products 2. One of the advantages of such an embodiment is of course that each pusher 6, or each pair of pushers 6 acting together on the same product 2, can be controlled or controlled independently. The movement of a pusher 6 is caused by a controlled actuator. Thus, the pusher 6 may for example be a rod of a jack. Since the positioning device 1 processes several products 2, it is provided with a plurality of orientation means 5, one per product 2 to be treated. The positioning device 1 can then have a series of pushers 6 aligned in the conveying direction 4, or a second series vis-à-vis. The actuation of the pushers 6 side by side may be the same, namely that, by construction, they are all animated the same movement at the same time. This may for example be the case when the pushers 6 are all mounted on a base connected to the rod of a single cylinder. In this case, the movement of this single jack defines the movement of each pusher 6.
    [0011] Alternatively, each pusher 6 may, by construction, be animated by a movement different from the others. This can be the case when an independent cylinder is associated with each pusher 6. The control of each cylinder can then be independent, and each pusher 6 can be driven in a different motion. In particular, the adjacent pushers 6 can move from their inactive position to their active position at different times, depending, as will be further described below, a detected spacing of the products, for example. At the input of the positioning device 1, the spacing between the products 2 is difficult to predict strictly. Indeed, even in the presence of any upstream equipment intended to spacing the products 2 on a regular basis, the distances between two successive products 2 are generally within a tolerance range, in particular plus or minus 10% of a median value. . The correct operation of the positioning device 1 then requires precise identification of the relative position of the products 2, in particular since the positioning device 1 is able to process several products 2 and therefore comprises several orientation means 5 of which the relative position and / or the instants of the triggering of the respective action movements must be controlled, in order to act in a synchronized manner in time and / or space with the sequence of the products 2. Thus, the device comprises for this purpose a detection cell 9 placed upstream of the at least one orientation means 5, which makes it possible to detect the successive presence of products 2 on the conveyor 10. The detection cell 9 is connected to a control unit which processes the generated signal and accordingly drives the plurality of orientation means 5, and in particular determines the relative position of the input products 2.
    [0012] The configurations where the positioning device 1 can process several products 2 have the advantage of being able to work at higher rates. Indeed, the pivoting operation about an axis perpendicular to the conveying plane 3 requires a certain time, and it is therefore more efficient to have several simultaneous positioning cycles or at least that are superimposed over time. Possible methods of implementing such a device will now be described. A first method consists essentially in positioning the pushers 6 relative to each other so as to reproduce the relative positioning of the plurality of products 2 that the positioning device 1 must process. This positioning of the products 2 as they arrive in the positioning device 1 is detected thanks to the detection cell 9 already described elsewhere. The successive orientation means 5 are thus displaced with respect to each other so that each product 2 of the plurality to be treated arrives at the same time at the level of the orientation means 5 which is intended for it: the first product 2 of the series to be treated arrives opposite the first orientation means 5 at the same time as the second product 2 of the series arrives opposite the second orientation means 5, etc. It is then possible to simultaneously cause the action movements of the different orientation means 5, which makes it possible to use one and the same actuator which controls the set of push-buttons 6 on the same side, or even two. To implement this method, the orientation means 5 must therefore have a possibility of relative movement in the conveying direction 4. Such a method therefore comprises a step of detecting the relative position of a series of products 2 to process, a relative positioning step of the orientation means, and a step in which the pushers 6 go from the inactive position to the active position. During the actual orientation step, the orientation means 5 must preferably move in the longitudinal direction, which can be done, on the one hand, by mounting the free orientation means 5 on the move. along the conveying direction 4, on a fixed slide 8 or on a carriage 7 movable in the same way, or, on the other hand, thanks to the carriage 7 in which they are mounted fixed longitudinally and which is movable in the direction 4. Once the orientation is completed, a longitudinal positioning step can be implemented, as described below. The cycle ends with the passage of the pushers 6 from their active position to their inactive position, then their return to position, which is to make them undergo a reverse movement to that they have undergone to track the progress of the 20 products 2 on the conveyor 10. In such a method, the irregularity of the relative positioning of the products 2 is thus managed by a relative displacement of the orientation means 5, which can then be manipulated simultaneously. In other methods described below, this irregularity can be managed by operating the orientation means 5 at different times. The appended FIG. 4 illustrates the concept of the most advanced product and produces the most rearward. In this case, the positioning device 1 is designed to process five products, referenced in the figure from a to e. The device comprises for this purpose five corresponding orientation means 30, referenced ctàc: sa to treat the product a, [3 to treat the product b, y to treat the product c, 8 to treat the product d and c for the product e. The position of the orientation means 5 therefore follows the desired referencing scheme. The distance between a product 2 and the corresponding orientation means 5 is identified from the orientation means 5 in the conveying direction 4. The product 2 for which this distance is the highest is therefore the most important product. in advance, and the product for which this distance is the smallest, possibly negative, is the most backward product. It will be understood that the classification of the products does not depend on the relative position between, on the one hand, the series of products, and, on the other hand, the series of orientation means 5 in their referencing scheme. In the case of the figure, the product b is the most advanced, then the product a, d, e and the most backward product is c. Thus, in this particular case, and as long as the orientation means 5 can not be moved relative to each other in the conveying direction 4 but only actuated independently, this set of orientation means 5 is moved so that that an orientation means 5 arrives opposite either the most advanced product or the most rearward product, for example for the product b and the orientation means (3). orientation, it is then sufficient to continue to move all the orientation means 5 relative to all the products 2 so that the other orientation means 5 come one after the other vis-à-vis the product corresponding, until the end, either with the most advanced product, or with the most backward product, for example the product c and the orientation means y.Of course, it is possible to start with any which product, then to drive accordingly the speed of the medium In general terms, the products are oriented starting by placing all the orientation means 5, immobile between them, so that one of them arrives vis-à-vis an end product, such as the most advanced product, or, respectively, the most rearward, and then moving this set of orientation means 5 so that they arrive successively opposite each other. one of the other products to orient it, until all the orientation means 5 is in a position such that one of them is opposite the other product of end, as the most backward product, or, respectively, the most in advance. As a function of the cases, the set of orientation means 5 moves, with respect to all the products 2 to be treated, either in the same direction as the products on the conveyor 10, or in the opposite direction. In the case of Figure 4, it is therefore possible to place the orientation means 5 so that one of them is vis-à-vis the product b and the oriente and then move them to the orientation is done successively for the products a, d, e, and finally the product furthest back, the product c. Conversely, it is possible to start with the product furthest back, the product c, and to move all the orientation means 5 to successively orient the products e, b, a, and d, when the respective orientation means 5 are successively facing each other, namely E, [3, a, then 6. If the operation starts with the product b, the orientation means 5 will have to move under speed relative to the flow so that the other products are successively oriented. Conversely, if the operation starts with the product c, the orientation means 5 will have to overspeed for the others. The most advantageous in terms of cycle time is to start with the one at the back, and to harvest the others with an overspeed. However, it is necessary to be sure to have as much product as orientation means 5, to ensure to have complete lots. This embodiment of the method is particularly suitable for cases where the orientation means 5 are fixedly mounted on mobile carriages 7: it is indeed sufficient to apply the logic described above by controlling, on the one hand, the initial position of the carriages 7, then their movement, and, secondly, the instants at which the orientation means 5 are actuated. In another embodiment of the method, the different orientation means 5 can be actuated independently and can be moved with respect to each other by a movement along the conveying direction 4. Each is actuated from that a product 2 arrives vis-à-vis him, which is identified through a sensor cell 9 upstream. Each orientation means 5 is successively manipulated, as a function of the product flow rate 2. It is thus possible to achieve the orientation function even for the cases where the products 2 arrive with a random spacing between them. The longitudinal movement speed of the orientation means 5 may be that of the conveyor 10, or may be different which allows, for example, to retain the products 2 until it has collected and grouped a predetermined number. The method according to the invention may further comprise an additional step during which the treated products 2 are placed, along the conveying direction 4, according to a predefined diagram in the conveying direction 4. orientation 5 form indeed two stops, each on one side of the product 2 in the direction of conveying 4. By moving an orientation means 5 in the conveying direction 4, it is possible, when it is in the active position, to move a product 2 forward or back separately.
    [0013] Such a step therefore makes it possible to produce groups of products 2, or else to put them in step, that is to say to space them from each other with a predefined and repeated distance. In cases where the longitudinal movement of the orientation means 5 is used to make groups of products 2, it may be advantageous to retract in their inactive position the pushers 6 which arrive between two products 2. The products 2 of a same group can then be in contact with each other, which is not possible if the orientation means 5 extend transversely between the products 2. The product group 2 is then held between two end pushers 6 , namely, on the one hand a pusher 6 foremost in the flow direction, and, on the other hand, a pusher 6 furthest back in the flow direction. These two end pushers respectively belong to the orientation means 5 intended to act on the first and last products 2 of the batch. The other pushers 6, after having retracted to allow the products 2 to come against each other, can then come into an intermediate position, in which they arrive at the interface between two products 2 successively without however dismissing them . This makes it possible in particular to stabilize the products 2. The processes according to the invention may also have an additional step during which the products 2 are offset, under the action of the orientation means 5, transversely to the conveying direction 4 It is thus possible to divide the product stream 2 into two parallel streams. The rotation of the products 2 can be of any angle, in particular at an angle of 90 or 45 degrees. This rotation is, however, generally accompanied by a change in longitudinal dimension. As already mentioned, an orientation means 5 forms a pair of abutments, one towards the front of the stream and the other towards the rear. The rotational movement is also achieved in particular by the fact that, in the conveying direction 4, the distance between these two stops is smaller than the dimension of the product 2 to be oriented. During the rotation of the product 2 about an axis perpendicular to the conveying plane 3, the dimension of the product 2, measured parallel to the conveying direction 4 may vary, and the two stops may then no longer be in position. contact with the product 2. The latter is then poorly controlled. It is therefore advantageous that the distance between the stops can be changed during the orientation maneuver. For this purpose, when the orientation means 5 enters into operation, the distance between the two pushers 6 which it comprises, or between the pusher 6 which it comprises and another stop, is modified by the displacement of one any of these two elements. Although the above description is based on embodiments, it is in no way limiting to the scope of the invention, and modifications may be made, in particular by substitution of technical equivalents or by a different combination of all or part of the characteristics developed above. In particular one can imagine that treatment scenarios different from those described are applied.
