    Transfer of products in enclosures to or from an accumulation surface
    The present invention enters the field of conveying products within an industrial line for continuous processing of said products, in particular the transfer of products to or from an accumulation surface.
    Such products can be, without limitation, containers such as bottles, cans, cardboard bricks, or even such containers grouped within boxes, cases, cartons or bundles.
    In known manner, such products are moved along said industrial line, between successive treatment stations, by means of suitable conveyors, essentially of the endless belt type. In addition, said products are processed and conveyed in a line or several parallel lines, namely in a single or multi-wire manner. In addition, during this conveying, the products of each line can be arranged in a specific manner, in particular spaced and / or oriented.
    Generally, in order to ensure the continuous production of such an industrial line, in spite of the stopping of a treatment station or for reasons of different rates of treatment between two stations, one or more zones of accumulation of said said are provided. products, each accumulation zone ensuring the temporary storage of a variable quantity of products between a post located upstream and a post located downstream with respect to said accumulation zone.
    According to a particular configuration, such an accumulation zone can be in the form of an accumulation surface, making it possible to receive and move said products grouped in columns, from an inlet to an outlet. Upstream, an inlet conveyor feeds said accumulation surface at an inlet edge via a first transit zone, according to one or more product lines, while downstream, an outlet conveyor receives a or several columns of products from said accumulation surface via a second transit zone along its exit edge, located opposite said entry edge.
    In order to move the products to and from the accumulation surface, the first and second transit zones are therefore provided respectively upstream between said inlet conveyor and the accumulation surface, and downstream between said surface d accumulation and said outlet conveyor. They make it possible to ensure a circulation of the products in a continuous flow, despite a sequential transfer of the said products in columns respectively to and from the accumulation surface, by pushing one or more columns in a transverse movement relative to the direction of circulation. longitudinal of the products.
    It will be noted that between the accumulation surface and these transit zones, sliding surfaces are often positioned, constituting fixed surfaces to which the products are transferred.
    A recurrent constraint resides in this transfer by pushing of the products at the levels of the first and second transit zones, to or from said accumulation surface, crossing interfaces between the different surfaces of said zones, in particular via the sliding sole constituting intermediate surfaces. immobile. Indeed, even in outcrop with the accumulation surface and the first or second transit zone, the junction with the sliding sole entails a risk of catching the bottom of the products during their passage at this level. In addition, accelerations and decelerations cause collisions, which could unbalance the products, or even cause them to fall. Similarly, during the transfer on each sliding sole, the thrust induces a friction of the products, a product being then likely to shift or again lose balance, fall, or even break in the case of '' a glass container. In addition, bringing an organ intended to ensure said thrust into contact with the products can also cause a shock inducing an imbalance of said products at the time of their transfer.
    An existing solution consists in positioning an additional member, in parallel opposite the thrust member, in order to frame the column or columns of products to be transferred. In particular, the spacing between the members is determined as a function of the width or the diameter of the products to be transferred. Such spacing can be provided adjustable depending on the size of the products, but necessarily requires a functional clearance to ensure, on the one hand, the circulation of products between the organs when they are positioned on either side along d 'a conveyor and, on the other hand, for the vertical movement of said tools, downward and upward. First, the functional play allows the transfer tool to come over at least one column of products from above, without touching them so as not to risk making them fall. Secondly, once the products have been transferred, said functional clearance allows the tool to be raised to return to its original position in order to transfer other products. Such a game thus allows the tool to be inserted and retracted at the level of one or more columns of products, even if the products belonging to the same column are not perfectly aligned, which is generally the case. in practice.
    Thus, a first member located on one side of a column of products is spaced by a first distance, while the member located on the opposite side of said column is spaced by a second distance, said first and second distances constituting the aforementioned functional game.
    Said functional clearance between the products and the members is in principle provided for at least five millimeters, up to thirty millimeters. Most often, said functional clearance is between ten and twenty millimeters.
    Generally, the adjustment of this spacing is carried out at the start of production, in particular according to the dimensions and the shape of the products to be transferred and is kept throughout production. This adjustment is generally effected by bringing the members closer together or apart from one another. This operation is generally carried out each time the format of the products to be transferred is changed. Therefore, after adjustment, this functional clearance is fixed and is no longer modified.
    However, if the necessary functional clearance makes it possible to prevent the fall of products during their transfer, it does not ensure that they are held in position during their transfer in a transverse movement, which may cause a shift in orientation or positioning one or more products.
    In particular, if a product shift occurs at the input when moving from the first transit zone to the accumulation surface, then the column alignment of said products is modified. This may result in an output problem when transferring such a column of misaligned products from the accumulation zone to the second transit zone. Indeed, the organs can potentially collide and therefore cause falls, or even breakage of products from said column or from an adjacent column.
    In addition, the functional play induces slow acceleration and especially deceleration expected during transverse movements. Indeed, these speeds depend on the products, their mass and their stability (essentially coming from the shape of their bottom), generating a proportional coefficient of friction of the bottoms of the products on the surfaces. The slowness of the accelerations but especially of the decelerations allows to maintain the alignment in column of the products. It is then impossible, with a functional game to operate transfers at a high rate.
    The invention aims to overcome the drawbacks of the state of the art by proposing a product transfer method, ensuring improved maintenance of said products during their transverse movement. In particular, the invention envisages enclosing each column of products between two members, at the time of their transfer, before or during the transverse movement. This clamping is provided so that said members come closer to the products until they come below said functional clearance, or even until they come into contact with the side walls of the products, without applying any stress to them.
    It should however be noted that in certain exceptional cases, in particular in the conveying of products with a non-rigid envelope, of the sachet or pocket type, it is possible to enclose said products until exerting a constraint, such as pinching.
    Thus, the invention relates to a process for transferring products to or from an accumulation surface within a continuous processing line for said products, in which:
    - One feeds longitudinally along at least one line of products by an input conveyor, a first transit zone along an edge of said accumulation surface;
    - A second transit zone supplies longitudinally along at least one product line an output conveyor, said second transit zone running along the opposite edge of said accumulation surface;
    - At least one column of products is transferred by transverse thrust, from said first transit zone to said accumulation surface, or else from said accumulation zone to said second transit zone, by means of a transfer tool provided a plurality of longitudinally extending members;
    - there is an organ on either side of each column of products;
    characterized in that at the time of transfer, each column of products is surrounded by relative approximation of said members.
    According to additional characteristics, in no way limiting, within such a transfer process, it is possible to grip each column before said transverse thrust, while the products are stopped.
    Each column of products can be gripped during said transverse thrust.
    At least a first member can be fixed, while at least a second member is mounted movable relative to said first fixed member.
    At least two members can be mounted movable symmetrically with respect to said first fixed member.
    All the members can be provided movable relative to said tool.
    The members can be displaced in translation in parallel in a horizontal plane.
    The members can be interconnected through at least two connecting rods, said connecting rods being pivotally mounted on each member, so as to form at least one mechanism with four deformable parallelogram type bars.
    In hooping each column of products can be spaced with said members by a distance less than a functional clearance.
    Said distance can be less than five millimeters, preferably between zero and three millimeters.
    The invention also relates to a device for transferring products to or from an accumulation surface, with a view to implementing said transfer method.
    Such a transfer device comprises:
    - an accumulation surface:
    - a first transit zone extending at least partially along an edge of said accumulation surface;
    - a product feed inlet conveyor along at least one line, from said first transit zone;
    - a second transit zone extending at least partially along the opposite edge of said accumulation surface;
    - an outlet conveyor supplied with products by said second transit zone;
    - At least one transversely movable transfer tool ensuring movement by transverse thrust of each column of products to or from said accumulation surface, respectively from said first transit zone or to said second transit zone, said transfer tool comprising at at least two spaced parallel members, so as to frame each column of products;
    characterized by the fact that it comprises means for actuating said members, from a separated position to a close position, according to a stroke in close proximity ensuring in close position a distance less than a functional clearance between said organs and each column of products.
    According to other additional, non-limiting characteristics, within such a transfer device, each tool can comprise at least two shafts pivotally mounted at the level of each member and movable below in rotation relative to said tool, so as to constitute a mechanism with four bars forming at least one deformable parallelogram.
    Each member can be in the form of a vertical plate oriented longitudinally.

    The present invention relates to the transfer of products 1 to or from an accumulation surface 2, within a continuous processing line for said products 1.
    In particular, as shown in FIG. 1, said accumulation surface 2 is surrounded by a first transit area 3 and a second transit area 4. The first transit area 3 extends along an edge of entry of the accumulation surface 2, while the second transit zone 4 runs along its opposite exit edge. The areas 3,4 therefore extend parallel or substantially parallel.
    In the direction of circulation of the products, from upstream to downstream, the first transit zone 3 is supplied along at least one row of said products 1, preferably in a single row, frontally by an inlet conveyor 5. Said inlet conveyor 5 receives the line of products 1 from a station located upstream within the processing line. In the nonlimiting example of FIG. 1, the single-line supply takes place from left to right, longitudinally or parallel to the entry edge of said accumulation surface 2. Then columns of products 1 are transferred each row in a transverse movement from the first transit zone 3 to the accumulation surface 2. In other words, the product columns 1 are moved in a generally horizontal plane, preferably but not limitatively orthogonally to their front supply direction, so as to cross the edges separating the first transit zone 3 and the accumulation surface 2 (as visible in FIG. 1, from top to bottom). The columns thus transferred are then routed on the accumulation surface 2 to the second transit zone 4. This routing can be carried out by suitable means, accompanying the columns in movement, such as for example through a carpet endless belt constituting said accumulation surface 2. With reference to Figure 1, said routing is carried out from top to bottom. A transfer is then carried out from the accumulation surface 2 to the second transit zone 4, always according to a transverse displacement, namely preferably orthogonally, relative to the direction of supply of products at the level of the inlet conveyor 5 ( as shown in Figure 1, from top to bottom). The columns then cross the edges separating the accumulation surface 2 and the second transit area 4. The latter then supplies longitudinally, according to at least one product line 1, an outlet conveyor 6 (as visible in FIG. 1, from the left to the right) . Said outlet conveyor 6 then sends the products 1 to a module located downstream in the processing line.
    In short, the transverse movement during each transfer of products 1 comprises at least one component perpendicular to the longitudinal direction, namely the direction of supply according to the inlet conveyor 5.
    Further on, the transverse movement during each transfer of one or more columns of products 1 is effected by transverse thrust. To do this, there are dedicated organs 7 on either side of each column. Each product 1 in a column is then surrounded by two organs 7.
    Such members 7 are adapted to come against the products 1 of the same column and allow their simultaneous pushing. Further on, it is at least one member 7 located upstream which operates the thrust, while the other member 7 located opposite retains the products 1 during their transverse movement, limiting their risk of falling .
    To do this, each member 7 can be in the form of an elongated element, preferably in the form of a plate extending vertically and longitudinally. The length of each member 7 is configured as a function of the dimensions of its transit zone 3, 4 and of the accumulation surface 2, in particular for sweeping all or part of their length, ensuring the transverse movement of the products 1. Therefore , the members 7 are mounted on means ensuring their movement, namely a transfer tool 8 at least movable transversely, always with respect to the direction of supply of the products 1 as input. Said members 7 can be mounted suspended at the lower part of their transfer tool 8. The travel of the transfer tool 8 takes place above the transit zones 3, 4 and the accumulation surface 2. In particular, a transfer tool 8 is provided at the first transit area 3 and another transfer tool 8 at the second transit area 4, each having dedicated travel cycles and strokes. transfer tool 8 is also provided vertically movable, ensuring, on the one hand, the elevation of the members towards a high position above the transit zone 3, 4 and the accumulation surface 2, to a sufficient height so that the bottom of the organs 7 thus raised do not come into contact with the top of the products 1. On the other hand, the vertical mobility of the transfer tool 8 ensures the descent from said high position to a low position in which two organs 7 frame a column of products 1. Above, two members 7 are mounted spaced apart, along a width depending on the format of products 1, in particular their diameter or thickness. This width corresponds in principle to the diameter of the treated products 1, to which is added a functional clearance, in order to allow the ascent and descent of said members 7 without coming into contact with the products 1. This functional clearance is constituted by a first distance located between the member 7 and the wall of the products 1 located upstream and a second distance located between the opposite member 7 and the opposite wall of said products 1 (ie located downstream).
    Such a functional clearance can be provided adjustable, manually or automatically, at the start of production and according to the dimensions of the products 1. Said functional clearance is generally at least five millimeters and at most thirty millimeters (between 5 mm and 30 mm). Preferably the functional clearance is between ten and twenty millimeters (between 10 mm and 20 mm).
    Advantageously, the invention provides, at the time of transfer, for enclosing each column of products 1 by relative approximation of said members 7. In other words, each column being surrounded by a pair of two members 7, the approximation of said members 7 is controlled .
    More precisely, at the end of the race, the members 7 are found spaced at a distance less than said functional clearance. In the close position of the members 7, this distance is generally less than five millimeters (5 mm), namely strictly less than 5 mm. Preferably, this distance is between zero and three millimeters (between 0 mm and 3 mm).
    In addition, when said distance is zero, then the members 7 come into contact with the walls of the products 1. It will be noted that this contact takes place without applying any constraint to the integrity of the products 1, without pinching, namely without deforming the container constituting each of said products 1.
    Consequently, this clamping by the members 7 makes it possible to maintain the products 1 for their transfer, by minimizing or even seeing leaving no space capable of authorizing a shift of the said products 1. Furthermore, in the case of a clamping on the part and on the other hand against the products 1, the approximation ensures the alignment of each column, namely longitudinally, in the direction of supply.
    Said bringing together of two members 7 is carried out in a relative manner, namely that the moving in approach of said members 7 can be carried out in a frame of reference centered on the products 1 to be enclosed. In particular, one of the members 7 moves relative to the other or else the two members 7 move. This movement is possible because one and / or the other of the members 7 is mounted movable relative to the transfer tool 8 which supports them below.
    According to a first embodiment, at least a first member 70 is fixed, while at least a second member 71 is mounted movable relative to said first fixed member 70. Such a configuration is visible in FIGS. 3 and 4, showing a transfer tool 8 equipped with two members 7: the movement of the movable member 71 located on the right is effected towards the fixed member 70 on the left.
    According to another configuration, generally, when the transfer tool 8 comprises more than two members 7, in particular three members, as visible in FIGS. 5 and 6, the first fixed member 70 can be located in the center, while two other members movable 71 are located on either side of said first fixed member 70. Consequently, the other two members 70 are mounted movable symmetrically with respect to said first fixed member 70. In addition, the strokes of the movable members 71 can be symmetrically similar.
    Additional movable members 71 can be envisaged, with a view to framing and ensuring the tightening of additional columns.
    According to a second embodiment, all the members 7 are provided movable relative to the transfer tool 8. For example, FIG. 9 shows four members 7 mounted movable and enclosing three columns at the level of the second transit zone 4 .
    Preferably, the movement in movement of the members 7 between them takes place in a translation parallel in a horizontal plane. In other words, each movable member 71 remains vertical and parallel during its approach with respect to the other fixed 70 or movable members 71.
    In order to obtain such displacement of said members 7, a first non-limiting embodiment provides for connecting said members 7 to one another through at least two shafts or connecting rods, said connecting rods being pivotally mounted on each member 7, so as to form at least one mechanism with four deformable parallelogram type bars. In addition, said connecting rods are mounted and actuated in rotation by said transfer tool 8.
    More precisely, each tool 8 comprises at least two shafts or connecting rods pivotally mounted at each member 7 and movable below in rotation relative to said tool 8.
    According to another embodiment, said members 7 can be mounted on slides which are parallel to each other and extending in a transverse direction, thus ensuring the transverse translation of the members 7. Actuation along such slides can also be achieved by through said transfer tool 8, in particular by suitable motorization means.
    Further, the movement in relative approximation of the organs 7 takes place at the time of the transfer of the products 1. In particular, said displacement in relative approximation of the organs 7 can be carried out at the start or during the transfer from the first transit zone. 3 to the accumulation surface 2, or from said accumulation surface 2 to the second transit zone 4. To do this, it is possible to grip each column of products 1 before said transverse thrust, while said products 1 are stopped , as shown in the example in Figure 3.
    Alternatively, as shown in FIGS. 4 and 6, it is possible to grip each column of products 1 during said transverse thrust, while the displacement of each column is in progress. This advantageously results in an increased rate.
    It will be noted that the movement in clasping of the members 7 can also be carried out in several stages of displacement by several successive transverse thrusts within the transit area 3,4, and between said transit area 3,4 and the accumulation surface . Such a possibility is envisaged for example when a transit zone 3, 4 is provided with several distinct surfaces, intended to receive and / or transfer several columns of products 1.
    Between each transit area 3,4 and the accumulation surface 2 can be positioned along the contiguous edges, at least one sliding sole 9. Such a sliding sole 9 constitutes a fixed, essentially flat surface, flush with the surfaces located on both sides. This sliding sole 9 is intended to close the hollow between the edge of the transit zone 3, 4 and the adjacent edge of the accumulation surface 2, forming a rounding, in particular when this surface 2 is formed by a belt conveyor without end wrapped around rollers. Each sliding sole 9 thus fills this hollow and this rounded shape, by forming a fixed surface, in flush, in order to prevent the products 1 moved to this location from being unbalanced and falling, or even breaking. Such a sliding sole 9 is visible in the examples of FIGS. 2 to 6.
    Each transit zone 3, 4 can be configured differently, in particular as a function of the number of columns transferred, in order to ensure the continuity of circulation despite the stages of transfer by transverse thrust of one or more of said columns.
    Several possible configurations of transit zones 3, 4 will now be detailed, without limitation.
    According to the example shown in Figure 7, the first transit area 3 is formed in part by the inlet conveyor 5, then extending over all or part of the length of the inlet edge of the accumulation surface 2. Likewise, the second transit area 4 is formed in part by the outlet conveyor 6, also extending longitudinally and parallel to the opposite edge of said accumulation surface 2. In addition, each transit area 3, 4 is provided with an intermediate conveyor 10, extending parallel and longitudinally, between the accumulation surface 2 and said inlet conveyor 5 or else said outlet conveyor 6.
    Each intermediate conveyor makes it possible to receive a column of products 1 during a first transfer step within said transit zone 3,4. In particular, at the first transit zone 3, an intermediate conveyor 10 is located between the inlet conveyor 5 and the accumulation surface 2, said intermediate conveyor 10 receiving a first column from the line of products 1 supported by the input conveyor 5. This first column is sent to said intermediate conveyor 10 during a first transfer step by transverse thrust at an angle, while another column of the queue continues to advance along said input conveyor 5. To do this, the intermediate conveyor 10 is set in motion, in particular in synchronization with the input conveyor 5. This step is particularly visible in FIG. 7. Once the first column has been moved on the conveyor intermediate 10, the latter is slowed down, or even stopped in order to operate another step of transfer by transverse thrust orthogonally from said intermediate conveyor 10 ver s the accumulation surface 2. Thus, the inlet conveyor 5 maintains its operating speed during the transfer of the products 1, thus ensuring a continuous circulation of the products 1, while the intermediate conveyor 10 operates at a variable speed, in particular according to a running mode at the same speed as the input conveyor 5 / stop.
    At the second transit zone 4, the configuration is similar, with the difference that a column is moved transversely and orthogonally during a first transfer step from the accumulation surface 2 to the intermediate conveyor 10 , located between the accumulation surface 2 and the outlet conveyor 6, then slowed down, even stopped. Then, it is set in motion, in particular synchronized with the outlet conveyor 6, and this column is transferred transversely at an angle during another transfer step towards said outlet conveyor 6, which in principle operates at a speed constant, thus ensuring a continuous flow of products 1.
    In this configuration, each transfer tool 8 is equipped with two members 7 which enclose a column of products 1 during one and / or the other of the above-mentioned transfer steps.
    At the entry, this clamping is preferably carried out at the time of transfer from the entry conveyor 5 to the intermediate conveyor 10 after the beginning of the transverse bias movement, or else from the intermediate conveyor 10 to the accumulation surface 2, after the start of the orthogonal transverse movement so as to carry out this step in masked time. Alternatively, the clamping can take place at the time of transfer from the intermediate conveyor 10 to the accumulation surface 2 but before the start of the transverse movement.
    At the outlet, a clamping can be carried out before or after the start of the orthogonal transverse movement from the accumulation surface 2 towards the intermediate conveyor 10, preferably after. Alternatively, it can be operated during the transverse displacement at an angle from said intermediate conveyor 10 towards the outlet conveyor 6. In the latter case, the relaxation and spacing of the members 7 can be controlled as soon as the products 1 transferred are supported by said outlet conveyor 6.
    According to the example shown in FIG. 8, the transit zones 3, 4 include a first conveyor 11 and a second conveyor 12, extending parallel and longitudinally. These conveyors 11, 12 are separated by a dead plate 13 of sufficient width to receive products 1 in a column.
    According to this configuration, the input conveyor 5, which operates continuously, alternately feeds the first and the second conveyor 11, 12 of the transit zone 3, which in principle operates alternately. In particular, the first conveyor 11 of the first transit zone 3 is on the way, in particular at the same speed as that of the conveyor 5, when it is supplied with a line of products 1 by the input conveyor 5 up to form a first column. Consequently, the line is oriented towards the second conveyor 12, while the first conveyor 11 is stopped. A first step of transferring said first column can then be carried out by transverse displacement, orthogonally, from said first conveyor 11 towards the dead plate 13 while a second column is being formed on the conveyor 12 in operation. Once a second column has been formed at the level of said second conveyor 12, the latter is stopped and the supply alternates again towards the first conveyor 11, then empty, which is put back into gear, in particular in synchronization with the input conveyor 5. The first and second columns can then be simultaneously transferred from the dead plate 13 and the second conveyor 12 to the accumulation surface 2, by displacement according to a transverse thrust, orthogonally. During this time, a new first column is formed at the level of the conveyor 11.
    A similar operation is carried out at the second transit zone 4. A first and a second column are moved simultaneously from the accumulation surface 2 respectively to a first conveyor 11 in principle stopped and a dead plate 13, at during a first transfer step. The first column is sent by the first conveyor 11 started, in particular at the same speed as that of the outlet conveyor 6, to this conveyor 6 which normally operates continuously and at constant speed, while the second column is moved by pushing transverse to the second conveyor 12, in principle stationary, where it will be sent to the outlet conveyor 6 after said first column, in its continuity, by starting, in particular synchronized, said second conveyor 12.
    In this configuration, each transfer tool 8 can be equipped with three members 7 enclosing the two columns of products 1 at the time of the input transfer from the dead plate 13 and the second conveyor 12 to the accumulation surface 2, or well at the outlet from said accumulation surface 2 to the first conveyor 11 and said dead plate 13. Clamping can also be optionally carried out at the time of the transfer at the inlet of the first column from the first conveyor 11 to the dead plate 13, or well out from the dead plate 13 towards said second conveyor 12.
    Each clamping can be carried out during the transfer, before the start of the movement, when the products 1 do not move, the corresponding conveyors being at a standstill, or preferably during the transverse movement, just after the start of the transverse thrust. , in order to perform this step in masked time.
    According to the example shown in FIG. 9, the inlet conveyor 5 feeds a first transit area 3 similar to that of the previous example according to a line of products 1. However, at the outlet, the second transit area 4 is formed integrally, over its entire width, by the outlet conveyor 6. In addition, said outlet conveyor 6 is dimensioned to receive several columns of products 1, in particular, in a non-uniform manner. limiting, three columns on the example shown. Consequently, the three columns are transferred simultaneously from the accumulation surface 2 to the outlet conveyor 6.
    It will then be noted that the outlet conveyor 6 can be constituted by at least two sections of bands, distinctly motorized, so as, on the one hand, to stop a first section opposite the outlet edge of the accumulation surface 2 for the purpose of transferring the columns of products 1, while another section, having previously loaded products 1, moves to a post located downstream to discharge them there. Once the transfer has been made, the first section is set in motion so as to catch up with said other section. The latter, once empty, will return with increased speed until it comes opposite the exit edge of the accumulation surface 2, where it stops to receive the following columns, and so after. Like the other configurations of transit zones 3, 4 described above, such a device makes it possible to debit a continuous flow of products 1 while the transfer is carried out sequentially.
    In this configuration, the transfer tool 8 located at the outlet at the second transit area 4 is equipped with four members 7 which enclose said three columns at the time of said transfer. Such a clamping can take place before the beginning of the transverse movement, but preferably after the beginning of the transverse thrust, in order to operate this action in masked time.
    In addition, once the transfers of each column have been made, the organs 7 are released, canceling any clamping, until returning to the initial position, in separation from the previous clamping approximation, according to the required functional clearance. This spacing allows, on the one hand, the release of products 1 without friction along the walls of said members located on either side of each column, and on the other hand, the rise and then the descent of said members 7 if this operation is required.
    Thus, the bringing together of the organs 7 at the time of the transfer of column of products 1 at the level of the transit zones 3,4 situated at the inlet and outlet of an accumulation surface 2, ensures improved maintenance of said products 1, limiting the risks of shift or imbalance. This tightening also makes it possible to increase the production rate, increasing the accelerations during transfers of products 1, but above all by having stronger decelerations, without any risk of falling products 1. Indeed, products 1 are then maintained on both sides until they stop at the end of the transfer in transverse movement.
    Such a clamping also avoids any risk of blocking the bottom of the products 1, especially for bricks with a bottom with a parallelepiped base, at the junctions in flush between the different surfaces, in particular with each sliding sole 9.
