    194) TRANSFER OF PRODUCTS.
    FR 3 057 861 - A1 tüy) The subject of the invention is a device for transferring (1) products (2), which comprises, on the one hand, a means of supply (4) of said products (2), which moves them one behind the other in a feeding direction (3), and, on the other hand, an outlet conveyor (5), extending from the feeding means (2), transversely to the feed direction (3).

    - 1 Transfer of products
    The present invention relates to the field of equipment for the grouping and packaging of products in industrial quantities and relates, on the one hand, to a particular transfer device, and, on the other hand, to a method implementing this device.
    The field of packaging by group of products of the bottle, flask or other container type generally involves conveying products one behind the other, that is to say in a single-line column, which must then be transformed into a succession product groups, often organized in a matrix, with several products in line and several products in column.
    For this kind of transfer, EP2167409 is known, for example, which proposes to provide a comb provided with successive collection cells. The cells are Tune next to each other perpendicular to the direction of arrival of the products and are placed successively Tune after the other opposite the single-wire flow. This creates a group of products distributed perpendicular to the feed direction. The lots created are however perpendicular to the direction of entry, which may not be compatible with certain installations.
    EPI560772 discloses a conveyor on which circulates the input products in the form of a single-line column, successive push bars being provided to release, each at the same time, a group of products on an output conveyor which circulates with a acute angle to the input direction. However, it is necessary to provide equipment that creates a space on the entry conveyor between two successive lots.
    In general, in systems using a pusher which simultaneously releases several incoming products forming a batch to the side, it is common to provide upstream a space between successive batches, to allow time for the pusher to clear each batch. This has impacts on the complexity of the installation and its price, taking into account the additional device required upstream, as well as on the rate.
    The purpose of the invention is to improve this state of the art by helping to overcome the above drawbacks.
    -2 To do this, the invention proposes to provide that the transverse release tool at least temporarily follows the longitudinal movement of the products when it releases them transversely.
    The subject of the invention is therefore a device for transferring products, which comprises, on the one hand, a means for feeding said products, which moves them one behind the other in a feeding direction, and, d on the other hand, an output conveyor, extending from the supply means, transverse to the supply direction.
    This device is characterized in that it further comprises a rotary tool around an axis of rotation parallel to the feed direction, said tool having manifolds distributed radially around said axis and being movable in translation parallel to the direction of supply.
    The invention also relates to a method implemented by this device, namely a product transfer process comprising steps consisting in bringing products one behind the other in a feed direction, evacuating the products by successive batches of at least two products each, by a movement transverse to the feed direction, and release the batches of products in an exit direction transverse to the feed direction.
    This process is characterized in that the evacuation of the products is carried out using a tool driven by a rotary movement around an axis of rotation parallel to the direction of supply and is accompanied by a movement said tool which follows the supply of products.
    The invention will be better understood thanks to the description below, which is based on possible embodiments, explained in an illustrative and in no way limiting manner, with reference to the appended figures, in which:
    - Figure 1 shows schematically a possible installation of a device according to the invention
    FIG. 2 shows two particular states during the process, namely FIG. 2a, taking the products, and FIG. 2b, removing the products, and
    - Figure 3 describes the three successive stages during the rotation of products around their axis, seen from above.
    The invention therefore firstly relates to a device 1 for transferring products 2, which comprises, on the one hand, a supply means 4
    -3 of said products 2, which moves them one behind the other in a feeding direction 3, and, on the other hand, an outlet conveyor 5, extending from the feeding means 2, transversely to the direction of supply 3.
    This product flow enters the transfer device 1 by the feed means 4, which feed means or conveyor 4 can be a conveyor with a screw for orienting and bringing the product into line. These different supply means 4 possibly have the function, moreover, of creating a space between each batch 13 of products. Each batch of products thus formed by the feeding means is moved perpendicularly on an outlet conveyor 5.
    The transfer device 1 thus serves to move products 2 from a supply means 4 as far as an output conveyor 5 which moves them perpendicularly to the supply means 4. The supply means 4 preferably comprises a belt conveyor, on which the products 2 rest by their bottom and then extend vertically. It also optionally includes screws or bands for placing or not even turning, or even a device for detecting the relative position of the products 2 in the supply means. The supply means 4 can also, for example, comprise a brake system, such as for example longitudinal strips with vertical blank, which have the effect, for example, of slowing the products 2 relative to the conveyor below, and therefore d 'ensure an accumulation and a position of the products 2 against each other within the single-line column. The feed means 4 can therefore, if necessary, have means which delimit the flow of products 2 on both sides. The supply means 4 however has a portion, namely a downstream end, where the products 2 are accessible from the side, for action by the tool 6 as described below. In this end zone, or feeding zone, the transfer device 1 is therefore devoid of means delimiting on either side the channel in which the product flow 2 flows. It is from this end zone that the outlet conveyor 5 extends, perpendicular to the conveyor presented by the feed means 4, that is to say from one of its edges.
    Products 2 are preferably products 2 which circulate with an industrial rate, and have a flat base for their support and a perpendicular axis along which they extend, like a bottle, a can, a box, a bottle, etc.
    According to the invention, the device further comprises a tool 6 rotating around an axis of rotation 7 parallel to the direction of supply 3, said tool 6 having collectors 8 distributed radially around said axis and being movable in translation parallel to the feed direction 3, so that by the rotation of the tool 6, each successive collector releases a group of products 2 from the feed means 2 to the outlet conveyor 5.
    The rotary tool 6 rotates around its axis of rotation 7 and is positioned essentially in line with the end zone of the supply means 4, where it makes the products 2 accessible from the side. As will be described below, the tool 6 can optionally be movable in the exit direction 9.
    Generally, the tool 6 is positioned relative to the extension of the column of products 2 which enter so that the collector 8, which comes against the products 2 under the effect of the rotation of the tool 6, is located at least temporarily on the other side of the outlet conveyor 5 relative to the product column 2 or the batch 13 to be pushed. For example, the tool is positioned with its axis of rotation 7 approximately in the extension of the product column 2 moved by the supply means 4, or slightly beyond towards the outlet conveyor 5.
    The tool 6 is movable in the direction of supply 3, in the direction of movement caused by the supply means 4 when a collector 8 pushes the products 2, and in the opposite direction for the same movement for the collector 8 following.
    The collector 8 thus follows the longitudinal movement, in the supply direction 3, of the products 2, of which it must cause a movement in the exit direction 9, to bring them onto the exit conveyor 5. The collector 8 preferably has at the level from its end most upstream of the supply direction 3, a gripping surface which extends to oppose the progression of the flow, this surface coming to be inserted in the gap created between two concave products 2 or between two products 2 belonging to different lots.
    During the process, the products 2 are normally fed continuously by the supply means 4, and the tool 6 rotates continuously, as well as the outlet conveyor 5, which continuously releases the successive batches 13 which extract l tool 6 of the supply means 4.
    -5 A collector 8 is preferably used to act on several products 2 simultaneously, preferably at least two.
    It is understood that the rotation of the tool 6 displaces the products 2 perpendicularly to the feed direction 3. The outlet direction 9 is, preferably, perpendicular to the feed direction 3.
    According to a possible additional characteristic, the outlet conveyor 5 releases the products 2 in an outlet direction 9 perpendicular to the feed direction 3, the tool 6 being movable in the outlet direction 9, so as to accompany on a more long distance the movement of the products 2 from the supply means 4 to the outlet conveyor 5. The tool 6 is therefore movable in both directions of the outlet direction 9. It is understood that it moves in the same sense that the output conveyor 5 when one of its collectors 8, arrived at the end point of its rotation, releases the products there 2. It moves in the opposite direction to return to the same point for the next cycle.
    In certain embodiments, the tool 6 deposits the products 2 on a fixed surface, of the dead plate type. It then reverses in the direction of exit 9 and in the opposite direction. The products 2 are then pushed by bars of the cycler bar type, which then possibly form the outlet conveyor 5, which conveys the products 2 by pushing from their side. Such bars can also be used to push the products 2 on a belt conveyor, or output conveyor.
    According to another possible characteristic, each collector 8 has a succession of notches 10 one next to the other parallel to the axis of rotation 7, each notch 10 being intended to receive a product 2, or even more. In general, a notch 10 delimits an edge for the product 2, upstream and / or downstream of the feed direction 3, as well as an edge for a push towards the output conveyor
    5. The edges may have a more or less specific and complementary shape to the product 2, or else be carried by abutment means which then only delimit contact zones.
    By way of example, the notch 10 can be produced simply by, on the one hand, a bar extending parallel to the axis of rotation 7 to form the bottom of the notch 10 for the thrust towards the conveyor of outlet 5, and, on the other hand, a finger which extends from said bar, transversely, and which then forms a stop for the product 2 in its feed movement by the feed means 4. The notch 10 a
    -6 Preferably, however, a bottom which at least partially takes up the curvature of product 2, for better support.
    According to another possible additional characteristic, the bottom of the notch 10 is curved for continuity of the contact during the rotation of the tool 6. Thus, the bottom of the notch possibly has a concave section, observed perpendicular to the axis of rotation 7. It is thus ensured that the movement of the collector 8 is transmitted to the product 2 in the form of a force parallel to the plane formed by the direction of supply 3 and the direction of output, namely essentially a horizontal plane.
    In particular embodiments, the notch 10 has a profile which, when pushed towards the outlet conveyor 5 under the effect of the rotation of the tool 6, favors the rotation of the product 2 around an axis perpendicular to both the feed direction 3 and the exit direction 9 of the output conveyor 5. Indeed, by opting for a notch 10 which can approach the product 2 asymmetrically with respect to its own axis of symmetry perpendicular to its base, it is possible to cause a rotation of the product 2 around said axis.
    We can thus opt for a notch which only materializes a stop for the product 2 downstream relative to it in the direction of the supply of the products 2 and not also the upstream stop. The indentation then pushes the product creating an asymmetrical force, which will make it rotate.
    Finally, in particular embodiments, the device comprises a chassis 11 based on beams 12, and, on the one hand, a first motor driving the tool 6 in rotation about the axis of rotation 7 and mounted on a first beam 12 movable parallel to the axis of rotation 7, on which the tool 6 is cantilevered, and essentially vertical, and, on the other hand, a second motor driving the first beam 12 in translation along a second beam 12, horizontal, parallel to the axis of rotation 7.
    The second beam 12 thus defines a horizontal guide structure, in the feed direction, and is located essentially above the tool 6, itself above the feed means 4 and the outlet conveyor 5. The first beam 12, meanwhile, extends cantilevered downwards from the second beam 12, and therefore flows in the feed direction 3 to allow the tool to follow the movement of the products 2 when '' they push them on the exit conveyor
    -7 5. At the other end is mounted the tool 6, movable in rotation. The tool driving motor 6 in rotation is preferably on board the first beam 12.
    A subject of the invention is also a method implementing the device as described above, namely a product transfer method 2 comprising steps consisting in bringing products 2 one behind the other in a direction d 'lead 3, evacuate products 2 in successive batches 13 of at least two products 2 each, by a movement transverse to the supply direction 3, and release the batches 13 of products 2 in an outlet direction 9 transverse to the feed direction 3.
    The products are brought in by means of feed 4, then are evacuated in a planar sweeping movement as far as an outlet conveyor 5 which then moves them perpendicularly. One thus transforms an incoming single-wire flow, of products 2 one behind the other, into a flow which evolves perpendicularly, and which comprises successive batches 13, spaced from one another along the exit direction 9. The evacuation of products 2 is done by means of the rotary tool 6 mentioned above and has the effect of cutting the continuous flow of products 2 into a sequence of batches 13 spaced apart.
    The evacuation of products 2 is therefore carried out in batches 13, in the sense that it is carried out cyclically, each time for a group of products 2, or batch 13. As already mentioned, each cycle is ensured by a collector 8 or pusher with which the tool 6 is provided at its periphery and which acts simultaneously on several products 2.
    The release of products 2 is done downstream of the evacuation and takes place continuously, in the sense that the outlet conveyor 5 can be permanently animated with a movement. The feed means 4 can also operate continuously.
    According to the invention, the evacuation of the products 2 is done using a tool 6 driven in a rotary movement around an axis of rotation 7 parallel to the supply direction 3 and is accompanied by a movement of said tool 6 which follows the supply of the products 2, the speed of rotation of the tool 6 being in particular variable to reduce or even avoid the impact on the products 2 when it comes into contact. The movement is cyclic to accompany the advance of the products 2 along the feed direction 3 while the tool 6 causes, by its rotation, a displacement
    -8 transverse to the axis of rotation 7 and to the direction of feed 3, parallel, namely the evacuation.
    The movement is thus synchronized: the tool 6 moves at the same speed as the mean supply conveyor 4 during at least part of the product removal step 2, then goes back to the initial position to process the batch 13 following. This makes it possible not to stop the products 2 between two batches to create a hole for the insertion and the transverse movement of a pusher.
    The tool 6 is thus provided with several collectors 8 distributed at regular angles along its circumference, and each collector 8 is intended to act on at least one product 2, thanks to at least one notch 10 which carries contact surfaces.
    When the products 2 are evacuated by the tool 6 due to its peripheral speed, said tool 6 moves in the same way as the products 2 in the direction of feed 3 relative to the ground: same direction, same direction and same speed, at least temporarily. One of the advantages of following the speed is to reduce the movement of the products 2 relative to the support surface to a movement in the direction of exit 9.
    In general, the speed of the tool 6 along the feed direction 3, when it follows the products 2 which it has to evacuate, can correspond to that of the products 2 until the batch 13 at offset is no longer vis-à-vis the column of incoming products 2, or even be greater if the tool 6 wants to be used to create a spacing between batches 13. It is also possible to reduce the speed of the tool 6 to force the products 2 to pivot under the effect of the supply means 4, then overspeed relative to the tool 6. Of course, as this movement along the supply direction 3 is to be performed each time cycle, the tool 6 circulates alternately in the same direction as the products 2 which it processes, then in the opposite direction, to return to the position for the next batch.
    It will be noted that, preferably, the conveyor of the feeding means 4, which may be the feeding means 4 itself, is preferably sufficiently wide to accommodate two columns of products 2 at the front. Indeed, it may be advantageous to shift the batch 13 of products 2 transversely with respect to the column and that it remains in contact with the conveyor during the whole evacuation operation, so as to avoid changes in longitudinal speed too important.
    -9According to a possible additional characteristic, the tool 6 is animated with a movement transverse to the feed direction 3 to accompany the evacuation of the products 2 towards the outlet conveyor 5. This movement is also cyclical, since the tool 6 must be temporarily in position allowing a collector 8 of its periphery to come against the column of products 2, then allowing this same collector 8 to drop the products 2 on the outlet conveyor 5. This movement perpendicular to the supply direction 3 can be done in the direction of the output conveyor 5 when it is a question of evacuating the products 2. In addition to returning to position, a movement in the opposite direction of the progression on the output conveyor 5 can be useful for example to reduce the speed difference along this direction during the contact between the collector 8 and the products 2.
    According to another possible additional characteristic, the products 2 extend vertically, perpendicular both to the direction of supply 3 and to the direction of exit 9 which is perpendicular thereto, the displacement of the tool 6 along the direction d 'brought 3 during the evacuation of the products 2 being such that the thrust of the tool 6 by its rotation causes a change of orientation of said products 2 around their vertical axis.
    The relative axial movement along the feed direction 3 between the tool 6 and the feed means 4 is such that the notch 10 of the manifold 8 rotates the product 2 around the vertical axis. The tool 6 can thus, for example, temporarily during the cycle, have a slight underspeed relative to the feed means 4, the latter then pressing the products 2 against the notches, which, being of suitable shape, cause the products to rotate around the vertical axis.
    Finally, in certain embodiments, the products 2 are brought by the supply means 4, in the form of a conveyor belt, in a single-line column extending in the supply direction 4, then are evacuated on the outlet conveyor 5 by tool 6 in batches 13 which, each formed by the transverse thrust exerted by a collector 8 of tool 6, extends in the feed direction 4, and which are separated one on the other on the exit conveyor 5 along the exit direction 9.
    The spacing between two successive batches on the outlet conveyor 5 depends in particular on the speed of the outlet conveyor 5, and on the angular spacing between two collectors 8.
    - 10 We can consider that on the output conveyor 5, the products 2 are then pushed by transverse bars, of the type bars driven by chains or cycler bars, which allow to reference the products 2 by back pushing.
    In the embodiment illustrated in the appended figures, the transfer device 1 comprises a fixed structure in which the products 2 move.
    The supply means 4 preferably takes the form of a conveyor belt, on which the products 2 rest. They generally stand one after the other in a single-line column, which extends in the direction of supply. In some cases, the supply means 4 comprises a pair of counter-rotating screws, which move the products 2 thanks to their thread. The threads can be of changing shape during the advance of the product 2, in order to cause the rotation of the products 2, in particular of the products 2 with a non-circular base.
    The feed means 4 therefore brings products 2 one behind the other in an end zone from which they will be pushed on an output conveyor 5 which extends from said zone, in a perpendicular direction to the direction of supply 3 and named direction of exit 9.
    The outlet conveyor 5 extends perpendicularly to the feed means 4, that is to say perpendicular to the feed direction 3. The outlet conveyor 5 extends from an edge of the conveyor as the means of lead 4 leads to the end zone, if applicable. A fixed strip can be used to cover the groove formed between the edge of the supply means 4 and the return roller of the output conveyor 5.
    Thus, the transfer device 1 receives, at the input, the products 2 in the form of a column which extends in the direction of supply 3 at the level of the supply means 4, and delivers, at the output, on the conveyor output 5, lots 13, separated from each other on the output conveyor 5 in the output direction 9, each comprising at least one product 2 and preferably at least two aligned in the direction of the direction of brought
    3. Downstream of this transfer device 1, the products 2 in batch 13 are optionally separated in circulation corridors parallel to the exit direction 9, or else grouped together against each other by group.
    - 11 to form a matrix of products 2 ready to be packaged, by bundling, casing, or the like.
    This transformation which the transfer device 1 operates from a compact single-wire flow extending in the supply direction 3 to a transverse multi-wire flow of separate products 2, is carried out using a tool 6 described below, who works in the end zone where the products 2 are brought by the supply means 4.
    In operation, said tool 6 is driven by a controlled movement of rotation about a rotation axis 7 parallel to the direction of feed. It therefore has for example a rotary plate, positioned downstream of the supply means 4, and from which extend manifolds 8. Each manifold 8 extends parallel to the axis of rotation
    7, and therefore to the direction of feed 3, from the plate, and overhang. Tool 6 therefore develops a tubular path at its collectors
    8. Each collector 8, under the effect of the rotation of the tool 6, exerts, on the products 2 delivered by the supply means 3, a thrust force which releases them transversely on the outlet conveyor 5 from the feed area.
    Each collector 8 thus has sufficient width to push several products 2 at once. To this end, in possible embodiments, the collector 8 can be provided with referencing surfaces for each product 2 separately, also called notches 10. A notch 10 thus makes it possible to limit the movement of a product 2 parallel to the direction outlet 9 as well as pushing the product by the rotation of the tool. The notch 10 may have a profile which is exactly complementary to the shape of the product 2 or else present only reference points or surfaces, for example defined by blocks mounted on the manifold 8, possibly mobile blocks for adjustment purposes.
    It is understood that the tool 6 is positioned so that when a collector 8 is in the low position, it reaches the height of the products 2 which are in the feed zone, so that they can be pushed laterally.
    The tool 6 has several collectors 8 distributed regularly and spaced apart from one another by a predefined angle, guaranteeing good balancing. The tool 6 is located in the extension of the feeding means 4 and acts at the level of the feeding zone where the position of the products is no longer delimited on the sides.
    The supply means 4 generally comprises a belt conveyor which extends to an end zone or supply zone, at the right of which the collectors 8 of the tool circulate. Thus, the products 2 continue to advance in the feeding direction 3 even though they are pushed transversely towards the outlet conveyor 5 by the tool 6. Furthermore, in order to reach high rates, the feeding means 4 operates continuously. In certain configurations, however, the supply means 4 possibly itself creates a slight longitudinal space between the batches 13 that the tool 6 will offset.
    In order to prevent the transverse thrust of the products 2 by the collector 8 from destabilizing the products 2, both those still upstream and those which it pushes, the tool 6 is animated with a movement along the direction of lead 3, to follow the movement of the products 2 relative to the ground. Thus, when one of its collectors 8 acts on the products 2, the entire tool 6 follows the movement that the supply means 3 makes the products 2 undergo, that is to say that it advances as them in the same direction in this direction. As described below, slight variations in speed are possible.
    The collector 8 in contact with the products 2 moved by the supply means 4 thus moves, at least temporarily, at the same speed as the conveyor that the latter comprises, in the corresponding embodiments.
    The tool 6 is therefore driven in a cyclic back and forth movement along the supply direction 3: it advances in the same direction as the products 2 when a collector 8 transfers products 2, then advances in the opposite direction to search for the next lot 13. In certain embodiments, this longitudinal movement of the tool 6 along the direction of supply 3 and in the direction of advance of the products 2 stops once the products 2 have arrived on the outlet conveyor 5 This avoids dangerous relative movements between the products 2 and their bottom conveying means, that is to say the feeding means 4 then the exit conveyor 5.
    More precisely, it is conceivable to stop the longitudinal movement of the tool 6 in the direction of supply 3 and in the direction of circulation of the products 2 as soon as the collector 8 which pushes the products 2 is no longer in screw opposite the column of products 2 to be subsequently treated. The product 2 most upstream of the batch 13 offset by the manifold 8 can then
    - 13 being caught up and then overtaken by product 2 furthest downstream from the column of products 2 to be treated subsequently.
    Thanks to this cyclical movement up and down the column of incoming products 2, it avoids destabilizing the products 2 or even blocking them when the collector 8 comes into action. The pace is also much better. Preferably, at least at the start of the action of the collector 8, it circulates with the same speed as the products 2 driven by the supply means 4.
    It is understood that the transverse transfer of the products 2 from the supply means 4 as far as the outlet conveyor 5 takes place by the peripheral thrust movement of the successive collectors 8, each movement forming a batch 13. In order to prevent the setting in contact between the collector 8 and the products 2 of lot 13 to be offset destabilizes them, and according to one possible characteristic, the speed of movement of the collectors 8 relative to the products 2, in the direction of exit 9, is reduced when the collector 8 comes into contact with the products 2. This creates a transverse acceleration, along the exit direction 9, sufficiently weak so that the products 2 do not undergo the equivalent of a shock.
    Preferably, the tool 6 has its speed of rotation reduced when a collector comes into contact with the products 2 compared to that it has otherwise. Its rotation is therefore at variable speed.
    In particular embodiments, the tool 6 can, moreover, move parallel to the outlet direction 9. This can be used, for example, to reduce the speed of the collector 8 during contact: the tool 6 can then be driven by a constant speed of rotation, but it is its movement along the exit direction 9 which adjusts the speed of the collector 8 relative to the product 2 along the exit direction 9.
    This possibility of displacement of the tool 6, that is to say of its axis of rotation 7, in the outlet direction 9, also allows a greater amplitude of displacement of the products 2 from the column that they form with the supply means 4 to the batches 13 offset on the side, even with a tool 6, the distance between the axis of rotation 7 and the collectors 8, that is to say the radius, is small .
    The architecture of the transfer device 1 can then comprise a chassis 11 based, for example, on beams 12. A first drive motor is provided to cause the translation of an assembly along the exit direction 9. Au within this set, we plan a second
    - 14motor, which is therefore mobile taking into account the movement described above, this second motor ensuring the movement of a module in the supply direction 3. Preferably, this module circulates along a horizontal beam 12, oriented in the direction inlet 3, and comprises a vertical beam 12, the upper end base of which serves as a guide. This module finally comprises, for its part, a third motor, driven by the movements described along the direction of supply 3 and along the direction of exit 9. This third motor in turn drives the tool 6 itself. rotation about its axis of rotation 7.
    It is understood that in certain configurations, the first motor is not useful and that the assembly which it makes movable along the exit direction 9 is then fixed relative to it. In addition, the sequence of movements relative to the ground may be different from that described above: the first motor is used to move an assembly in the direction of feed, the second to move it in the direction of exit, etc. In general, the linear movements are ensured by linear guides of the slide type, mounted in the beams 12 of the chassis 11.
    In certain embodiments, the collector 8 has a notch 10 per product 2 to be driven on the side. This notch is more or less of complementary shape to the product 2. The tool 6 can then be controlled in its movement along the supply direction 3 to cause the rotation of the product 2 about an axis perpendicular to the plane of its support and therefore normally vertical.
    Indeed, the feed direction 3 and the exit direction 9 define a normally horizontal plane. In certain configurations, the product 2 may have a horizontal section which has an asymmetry so that it is possible to define an angular position of such a product 2 around the vertical axis. In such cases, it may be necessary to turn the products 2 between the position they have when they are on the supply means 4 and the position they must have on the output conveyor 5, which is in particular described in the appended figures.
    The notch 10 may in fact include an end edge, for example the end of a spout, the side of which is intended to retain the product 2 in its movement parallel to the supply direction 3. When the collector 8 arrives on the products 2 to be moved, its relative position is such that this end edge comes not beyond the product 2 as is the
    - 15cases once product 2 stabilized in the notch, but comes against product 2, between its axis of vertical symmetry and its nearest edge.
    The rotation of the tool 6 then has the effect of exerting a force which is not symmetrical relative to the vertical axis of symmetry of the product 2 which causes the rotation of the product 2 around the vertical axis, see the figure. This rotary movement of the tool 6 continues until turning the product 2 possibly by a quarter of a turn, which makes it possible to pass the products 2 initially oriented with their long edge parallel to the supply direction 4 to an orientation with their long edge perpendicular to this direction.
    It is understood that this rotational movement of the tool 6 around its axis of rotation 7 for the purpose of product rotation 2 can be accompanied by a relative movement between the products 2 and the tool 6 in the direction of feed 4. For example, the manifold 8 can initially flow along the feed direction 3 with the same speed as the products 2, then, to complete the rotation around the vertical axis, continue with a slightly lower speed , which will have the effect that the supply means 4, more precisely the belt conveyor on which they rest, will force, by its action, the products 2 against a surface of the notch 10 which will be able to complete the rotation of the product 2.
    In addition, preferably, the notch 10, and more generally the collector 8 at its surface intended to be in contact with the product 2, has a curved profile, which has the effect of ensuring that the force exerted by the collector 8 on the product 2 is always, at least as much as possible, in the plane formed by the outlet direction 9 and the feed direction 3.
    As shown in FIG. 1, a transfer device 1 comprises a means 4 for supplying products 2 which come, for example, from a preparation machine situated upstream from the transfer device 1 such as a filling machine or a machine labeling, not shown in figure L
    The products 2 arrive in line, in a queue, by the feed means 4 such as an endless chain or belt conveyor, in a feed direction 3.
    At the upstream end of the feeding means, not shown in FIG. 1, there can be a pitching device in order to create a
    - 16 spacing in the product queue or a product orientation device in order to rotate the product along its vertical axis such as a product pitch or orientation screw.
    At the downstream end of the feed means is an outlet conveyor 9 oriented transversely to the feed means 4 and therefore to the feed direction 3 of the products. This outlet conveyor 5 feeds a machine, not shown, in a batch of products. This downstream machine can in particular be a shrinkwrapper.
    At the downstream end of the feed means 4, the products 2 are transferred from the feed means to the outlet conveyor 5 by the transfer device 1.
    The transfer device comprises a tool 6 rotating around an axis of rotation 7 parallel to the feed direction 3.
    This tool 6 comprises collectors 8 intended to receive batches 13 of products 7. They are distributed radially around the axis of rotation 7 and parallel to the direction of supply of the products.
    The collector 8 is a customizable part which can be changed or adjusted, in particular by adjustment, according to the batches 13 of products to be formed and transferred.
    Each collector is in the form of a succession of notches 10, one next to the other and parallel to the axis of rotation 7 or in the form of a push bar, pushing all the products into same time as far as the output conveyor 5 or on a dead plate from where they will be taken up by an element of the bar cycler type, for example.
    In the embodiment where the collector is equipped with notches, they have the shape of the product which they will capture and then carry out the transfer.
    In general, the bottom of these notches is curved to increase the continuity of contact with the base of the product to be grasped.
    The tool is also movable in translation parallel to the feed direction 3 of the products 2. This translational movement of the tool will be described in the following description.
    To perform these different rotational and translational movements, the tool 6 is mobile, carried and guided by a support structure which comprises a fixed frame 11 formed of beams 12 located partly above the supply means 4 and also partly located above
    - 17 output conveyor 5 to facilitate the transfer of the batch of products between the supply means and the output conveyor.
    A first motor, not shown, drives the tool 6 in rotation about the axis of rotation 7. This motor is mounted on a first vertical beam 12, on which the tool 6 is cantilevered, and above the means of supply 4.
    A second motor, not shown, drives the tool fixed in translation on the first beam 12, along a beam 12, horizontal, parallel to the axis of rotation 7 and to the direction of supply of the products.
    A third motor drives in translation the tool fixed on the first beam 12, along a horizontal beam 12, parallel to the outlet direction 9.
    Having a motor per movement allows you to vary the speed of the collector during the process and to have great flexibility.
    FIGS. 2a and 2b describe the steps in the operation of the transfer device 1.
    At the upstream end of the supply means 4, in FIGS. 2a and 2b, there is shown a pitching device such as a timer which can consist of either a pair of worms facing each other. screw or either a couple of endless chains or bands opposite. This timer operates upstream of the product transfer device 1 and downstream of the product preparation machine.
    The function of this timer is to compact the flow or even, if necessary, to create a spacing between each batch 13 of products 2 which will then be picked up by a collector 8. This spacing is achieved by reducing the speed of the timer relative to the speed means of supply
    4.
    The purpose of this spacing is to create the batch of products to facilitate the introduction of the collector into the product queue.
    As shown in FIG. 2a, the tool 6 has been translated in the direction of the timer in order to raise the line of products up to the downstream end of the timer. Then, one of the collectors 8 is synchronized with the batch of products to be captured, that is to say that the collector is set to the speed of the supply means 4 in the supply direction 3 of the batch. 13 products. On the other hand, at the time of contact between the products and the collector, the rotational speed of the collector is low, possibly
    - 18 almost zero, in order to avoid any imbalance in the products collected. Finally, once the batch of products has been captured and removed, the tool resumes a certain speed of rotation combined with a translational speed of the collector to raise the batch of product downstream of the supply means and this preferably with a translational speed of the collector greater than the speed of the supply conveyor.
    The translational movement of the tool 6 along the feed direction contributes to increasing the rate of operation of this transfer device.
    As shown in FIG. 2b, the tool 6 has moved up the product line downstream of the supply means and by the rotational movement of the collector, the batch of products has been deposited on the outlet conveyor 9.
    In a preferred embodiment, the tool 6 can also perform a transverse movement relative to the direction of supply 3 of the products.
    This transverse movement helps facilitate the removal of products and increases the range of products that can be treated with the same type of tool.
    Once the product batch removal step has been completed, the collector starts the cycle described above.
    Figures 3a, 3b and 3c describe the steps of the orientation process of products of particular shape, other than cylindrical or whose section is identical to itself once turned by a portion of a tower.
    During the implementation of this orientation process, the speed of the feed means 4 and the speed of the collector 8 in the feed direction 3 are substantially identical. However, depending on the product to be rotated, the speed may vary.
    As shown in FIG. 3a, the products 2 are in line, in a line, on the supply means 4 in a supply direction 3. The collector 8 is located parallel to the supply direction, and facing each other. with regard to the products to be oriented.
    In this embodiment, the notches 8 have the shape of a triangle, the apex of which is formed by two edges. This apex points to the products to be oriented when the collector 8 approaches it. According to the direction of supply 3, the upstream edge forming the top is the edge on which the product will roll to orient itself.
    - 19 As shown in FIGS. 3b and 3c, the manifold translates transversely relative to the direction of supply 4 of the products. This translational movement is generated by the rotational movement of the tool 6, or even by the additional movement of the tool 6 in this direction. This translational movement of the notch 10 causes the rotation of the products simultaneously along their vertical axes by pushing on the downstream end of the product 2. In other words, the translational movement of the notch causes the rotation of the following product its vertical axis by rolling the product on the upstream edge of the top of the notch.
    This product rotation device eliminates the upstream screw used to turn the products. Turning screws are tools dedicated to the shape of the products to be returned. They are heavy, imposing and of specific design. In addition, they often cause scratches, scratches or other damage to the surface of the product and its label. Rotation of the product by the tool itself helps to eliminate these problems.
    Thanks to the invention, it is thus possible to continuously extract groups of products from a queue, this at a high rate, and without destabilizing the products or requiring an upstream device to create spacing between the successive groups or batches. .
    Although the above description is based on particular embodiments, it is in no way limitative of the scope of the invention, and modifications can be made, in particular by substitution of technical equivalents or by any combination other than any or part of the characteristics developed above.
