• a de-consolidator has the reverse function, namely to increase the number of columns, in particular to move products from a single-wire configuration to a bulk configuration.
• the invention relates more particularly to the unbundlers.
• a de-consolidator has, on the one hand, a speed differential between two conveying portions, namely a fast conveying portion and a slower conveying portion, which then causes the products to position themselves side by side to maintain the overall flow, and, secondly, means for passing the products from the fast portion to the slow portion.
• FR2531046 discloses the use of an inclined plane for moving products from the fast portion to the slow portion. Robust operation, however, is very difficult to achieve at high speeds using gravity. Mechanical guides are nowadays privileged to ensure the passage from one to another portions. There are thus known embodiments in the form of a de-consolidator arranged in an angular zone of a conveyor.
• This embodiment has many disadvantages. Indeed, it can more easily lead to falls of products during the passage from one conveyor to another, given the greater gap between curved conveyors, resulting in particular from the higher wear.
• the drive direction in the slow portion is not homogeneous, which further destabilizes the products, especially at high speed.
• efficient unbundling can only be obtained if the angle between the two speed directions is important. At high speed, falls are very frequent.
• FR2604693 Also known from FR2604693 is a staged unbundling solution on parallel conveyors, in which the products arrive in a single-wire, then pass transversally transversely in a first conveyor having a sequence of two zones with a speed differential, then arrive on a second conveyor of exit, at even lower speed.

Under the effect of braking, the slowed products gradually accumulate against these guides and the pressure in this column can reach values such that the column bursts and a product is then violently ejected transversely. It is therefore not possible, with this kind of achievements, to reach high speeds and unbundle over a short conveying distance, requiring significant speed gradients.
• US4308944 also presents a staged unbundling, in which the products circulate on parallel conveyors having a gradient of speed, passing each time from a fast conveyor to a slow conveyor through an oblique guidance, along which the products come s' accumulate to create the problem already mentioned above of bursting of the column of products.
• a gradual slowdown in products leads to excessive lengths for the complete device.
• this embodiment illustrates a particularly problematic phenomenon at high speed: the end portion of the guide must extend transversely to the direction of advance to pass the products as quickly as possible to the slow portion, but, at high speed, the more this end portion is transverse, the more the products may be projected against the guide vis-à-vis and fall.
• a violent transverse offset increases the pressure within the upstream product column, further destabilizes the products, and intensifies the nefate centrifugal phenomena once the product is released from the guide.

• This kind of realization also leads to simultaneous reduction of speed and transverse displacement, which destabilizes too high-speed products.
• the pressure along the terminal guide can also become problematic, as described above.
• the object of the invention is therefore to improve the state of the art in the manner described above, and aims in particular to achieve unbundling over as short a length as possible, limiting the risks of falling products and reliable at high levels. rate, or about 80,000 products per hour or more.

• This device is characterized in that upstream of the slow portion, the fast portion has an upstream guide which is oriented angularly in the direction of the slow portion.
• the subject of the invention is also a process for implementing such a device, namely a conveying process in which the products circulate on a first conveying portion, referred to as a fast portion, and then on a second conveying portion, said slow portion, the circulation in the slow portion being linearly in a conveying direction, the circulation in the fast portion, before the products arrive on the slow portion, being in the form of a smaller flow and faster than in the slow portion.
• This method is characterized in that the circulation in the fast portion is in a main direction different from the conveying direction and gradually oriented towards the slow portion.
• FIG. 1 shows a device according to the invention, wherein the conveyors have not been shown, but only their own guides;
• FIG. 2 schematizes an embodiment where, upstream of the slow portion, the guidance is linear and the conveying curve

• the conveying device 1 thus has conveying means, such as carpets, chains or other, for conveying the products 11 as well in the fast portion 2 as in the slow portion 3. In the latter, the conveying means therefore extends linearly in a conveying direction 4, and are intended, in normal operation, to circulate the products 1 1 slower than in the fast portion 2.
• the conveyors of these two portions therefore do not have the same speed and independent control means can be provided for them.
• the speed of circulation of the products decreases by passing from the fast portion 2 to the slow portion 3
• the size of the product flow increases transversely correspondingly.

• the rapid portion 2 optionally has a decreasing velocity gradient approaching the slow portion 3, the latter possibly having a decreasing velocity gradient away from the fast portion 2.
• the fast portion 2 upstream of the slow portion 3, the fast portion 2 has an upstream guide 5 which is oriented angularly towards the slow portion 3, so as to laterally direct the products towards the slow portion 3.
• the invention therefore proposes to anticipate this offset towards the slow portion and to start it while the product 1 1 is still exclusively on the fast portion 2. The direction of the speed of the product 1 1 is therefore not modified during the passage on the slow portion 3.
• the upstream guide 5 takes in particular the form of a pair of guide walls, one on each side of the group of products 1 1 circulating in the fast portion 2.
• the upstream guide 5 is thus upstream of the slow portion 3, separated from the latter by a distance which decreases progressively in the direction of the flow of products, whereby the products are brought progressively laterally to the slow portion 3 even though they are still entirely on the fast portion 2.
• the upstream guidance 5 directs the products substantially linearly to the slow portion 3.
• the products 1 1 therefore undergo, at the level of the fast portion 2, or even at the beginning of their evolution on the slow portion 3, a linear linear motion oriented angularly towards the slow portion 3 and therefore its median axis, and with a relatively low angle, as will be explained further. Guiding the product does not change virtually no direction, which avoids destabilizing products.
• the upstream guide 5, on the one hand, and the convolution means of the fast portion 2, on the other hand have substantially the same direction of action on the products, and this on at least a portion or even the entirety of the rapid portion 3, so as to prevent slippage of the products on said conveying means that would prevent satisfactory control of the movement of products to the slow portion 3
• the guiding direction and the conveying direction are not the same, the products 1 1 slide on the conveying means, the latter then being able to apply a low drag force from the base of the products. .
• the upstream conveying means are not capable of To exert sufficient force on the products, these will accumulate until reaching a conveying portion still upstream which will arrive to put all the column in movement. It is therefore proposed here to arrange, at the level of the fast portion 2 and therefore close to the slow portion 3, an upstream guide 5 and a conveying which impose on the product the same movement, so as to be able to drive the products as soon as possible. close to the slow portion 3.
• the dimensions of the conveying device 1 can thus be reduced.
• the common profile of the upstream guide 5 and the corresponding conveying can have different shapes.
• the conveying and the upstream guidance 5 are for example both linear, or curved on the along a curved profile, whose center of curvature is on one side or the other with respect to the interface between the fast portion 2 and the slow portion 3.
• the upstream guide 5 can extend obliquely on a conveyor, possibly made of several chains, which can then simplify the construction, the conveyor being for example parallel to the conveying direction 4.
• the upstream guidance 5 stops at the beginning of the slow portion 3.
• a short extension of the upstream guidance 5 above the slow portion 3, that is, beyond the interface between the fast portion 2 and the slow portion 2 is conceivable so that the products, once they open into the slow portion 3 and are disengaged from the upstream guide 5, are optionally free to replace by a movement transverse withdrawal towards the nearest wall of the guide of the slow portion 3.
• Problems may arise if the upstream guide 5 extends excessively above the slow portion 3.
• the guidance over the slow portion 3 should preferably be short enough to prevent a column of products can be formed against it so as to avoid an accumulation of products and an increase in pressure that can lead to a burst of this column of pr oduits and therefore falls.
• the upstream guide 5 carries out a lateral offset of the products in a main direction which has, relative to the conveying direction 4, a low angle ⁇ , so as to avoid a too violent transverse displacement having the effect harmful to destabilize the products 1 1 and increase the pressure in the fast portion 2, in particular an angle 6 between 5 and 30 degrees, preferably between 10 and 20 degrees.
• the transverse offset thus represents a movement which, with respect to the conveying direction 4, has a transverse component but also a longitudinal component, the equilibrium between the two components ensuring an entry of the products on the slow portion 3 almost parallel to the direction conveying 4 or in any case only slightly angularly offset.
• the conveying device 1 further comprises a means of dynamic deformation of the end of the upstream guide 5 which is furthest downstream in the flow direction. Said end is thus animated with a movement transverse to the conveying direction 4, so that the orientation of the movement that gives the upstream guide 5 products 1 1 when they open on the slow portion 3 varies slightly in time.
• the transverse movement is preferably alternating and of low amplitude, applied near the free end of the wall. The latter is fixed relative to the frame at a distance from the free end. It is thus possible to send the products apart from each other in the longitudinal direction on the slow portion 3, which limits the risk of collisions and falls.
• Said end of the upstream guide 5 thus moves between two extreme positions, around a median position.
• the end In this median position, the end is aligned in the extension of the rest of the upstream guide 5, that is to say that it preferably has only a small angle with respect to the conveying direction 4.

• This transverse withdrawal, perpendicular to the conveying direction 4 frees additional space so that the products can be replaced without clashing once they leave the upstream guide 5.
• the subject of the invention is also a method implementing the device as described above in its different variants, namely a conveying process in which the products circulate on a first conveying portion 2, called the fast portion 2, and then then on a second conveying portion 3, said slow portion 3, the circulation in the slow portion 3 being linearly in a conveying direction 4, the circulation in the fast portion 2, before the products arrive on the slow portion 3, being in the form of a narrower flow and faster than in the slow portion 3, so as to perform a product unbundling between the fast portion 2 and the slow portion 3.
