Description

DEVICE FOR THE FORMATION OF LOTS OF PRODUCTS AND THE SEPARATION OF SUCH LOTS BETWEEN THEM AND THEM RECIPROCALLY FOR YOUR PACKAGING The subject of the present invention is a device for the formation of batches of products and the separation of said batches between them and reciprocally for their packaging. Product separation systems are currently known with the help of variable pitch screws, but these can not form batches except in the form of a row of units or of mrows placed side by side with a relatively large distance between them and not lots of grouped products. Devices such as the one described in the patent FR-A-2, 710, 317 are also known, which comprises a transfer belt extended between two vertical axle driving wheels and provided with regularly spaced fixing means, each one intended for the attachment of a wheelbarrow carrying a separation and maintenance element, of the cover type, movable in vertical translation or others which have the function of covering a certain number of products to form a batch, a variable pitch screw that allows to progressively create a growing space between said wheelbarrows and so on between the successive lots.

However, this type of device presents a significant problem due to the use of a variable pitch screw. The object of the present invention is to remedy this drawback by proposing a device that allows to form batches of products and separate said batches and reciprocally while occupying a volume lower than that of the existing devices. The device according to the invention is placed at the exit of an input conveyor of the products arranged in a single row and is essentially characterized in that it comprises at least two concentric trees, where each one, independently of the others, moves in rotation by a means motor, driven by a control system, and is equipped with a sector fixed perpendicular to said shaft and provides at its free end suitable cuts to get hold with the products introduced by the conveyor so that they form a batch of products, being determined the speed and acceleration parameters of each of these sectors, which are moved one after the other, by the control system that follows the different phases of formation and separation of the lots, namely: during the training phase of a lot a nominal speed allows one of the sectors to grab a batch of products at the same time that imposes its speed of displacement of the products on the transporter of ada; During the phase of separation of the batch formed by this first sector, an acceleration separates that sector from the sector that precedes it and that is in the phase of formation of another batch, introduces the first sector at a certain speed that allows it to transfer the batch, then from a path of approximately 180 °, to an output conveyor, - - the 360 ° cycle is completed by communicating to the first sector the nominal speed of seizure of the products and so on. The batches of products thus formed are transferred to the output conveyor and taken in charge by the supporting means as tacks integral with a chain or belt that advances along said output conveyor. According to a further feature of the invention, the device also comprises a disk, of axis parallel to the trees carrying the sectors, arranged tangentially to said sectors, and having cuts similar to those of the two sectors, which allow the transfer of lots of products over the output conveyor with a direction of advance identical to that of the product input conveyor. According to a further feature of the invention, the device according to the invention also comprises a curved conveyor arranged at the outlet of the product input conveyor and upstream of the sectors, which allows to transfer the batches of products on the output conveyor in a sense of advance identical to the conveyor of entry of the products. The advantages and characteristics of the present invention are more clearly reflected from the description that follows and which refers to the attached drawing provided by way of a simple illustration of the invention, to which it does not have any limiting character. In the attached drawing: Figure 1 represents a schematic perspective view of a device according to the invention. Figures 2a, 2b, and 2c represent plan schematic views of different phases of operation of the device according to the invention. Figure 3 represents a plan view of the device according to the invention associated with two other identical devices to form batches of products on three rows. If we refer to Figure 1 it can be seen that the device 1 according to the invention comprises three sectors 10, 11, 12 identical together each one perpendicularly to the upper end of a shaft 2, only the external shaft 20 is visible on the figure, these trees 2 are arranged concentrically with respect to their axis of rotation 21, and are of increasing length from the tree of larger diameter to the tree of smaller diameter, so that the sectors 10, 11, 12 are placed one above the other and are separated by a distance such that they are capable of moving, by means of the shafts 2, substantially in a same circular area in rotation around the axis 21. Each of the trees moves in rotation around the axis 21 thanks to an electric motor respectively 30, 31, 32, controlled independently of the others by an electronic control unit, not shown , by means of a pulley respectively 33, 34, 35 attached to the lower end of the shafts 2 and of a transmission belt respectively 36, 37, 38. also see that the sectors 10, 11, 12 have semicircular shaped cuts 13 practiced at their free end and capable of grasping each one a product such as a bottle. The shape of the cuts may be different depending on the products to be gripped without thereby departing from the scope of the invention. The control unit is programmed to send electrical signals to the motors 30, 31, 32, in order to give the sectors 10, 11, 12 by means of the shafts 2, a speed and / or an acceleration determined as a function of the different phases of training, separation and transfer of the batches of products. If we refer to Figure 2 you can see a device 1 that was placed at the exit of an input conveyor 4 of bottles 40 aligned in a single row, sectors 10, 11, 12 evolve in rotation in a plane parallel to the plane of said conveyor. It can also be seen that the device 1 according to the invention further comprises a disk 5 of axis of rotation 50 parallel to 21 of the shafts 2 having three series 51, 52, 53 of cuts 54 similar to the 13 of sectors 10, 11 and 12 and also intended to reach to catch the products 40 introduced by the conveyor 4 after taking them in charge of the sectors 10, 11, 12, so that they leave the device 1 on an output conveyor 6, held between the tacks 60 dragged by a chain or belt not shown, with a direction of displacement identical to that of the input conveyor 4. It can also be considered to arrange the disk 5 upstream of the sectors 10, 11, 12, just at the exit of the conveyor 4 tangentially to this, disc 5 would then have semicircular cuts around its periphery and would rotate in it. clockwise while the sectors 10, 11, 12 would rotate around the axis 21 of the trees 2 in the counterclockwise direction, or still replace the disk 5 by a curved conveyor arranged at the exit of the conveyor 4 upstream of the sectors 10, 11, 12. It will be noted that the device 1 also has two circular guides 7 and 7 'that hold the products respectively in the cuts 13 of the sectors 10, 11, 12, and in the cuts 54 of the disc 5 after the rotation of the sectors 10, 11, 12 and of the disc 5. The motors 30, 31, 32 are conveniently controlled by electrical impulses, which allows, by counting said impulses by means of a numerical computer integrated in the control system, determine with precision the angular position of the sectors at every moment and synchronize well the assembly of the moving elements that make up the device. The operation of the device 1 is as follows: The sector 10 of the device 1 that is located at the arrival of the conveyor 4 comes to grasp, with a nominal speed substantially equal to that of the conveyor 4, the first three bottles 40, while the sector 11 that precedes the sector 10 that comes from grabbing three bottles 40 begins its acceleration phase which has the effect of creating a space with the batch of three following bottles formed by the sector 10, the sector 12 which is approximately 180 ° from the sector 10 in the phase of holding the bottles, has a speed substantially equal to that of the disc 5 and is synchronized with it so that it can transfer its batch of bottles 40 to the disc 5 in the cuts 54 of a series 50 that is presented in relation to the sector 12. Then, as can be seen in figure 2b, the sector 12 that comes from transferring its batch of bottles to the disc 5 goes into the deceleration phase until it reaches the nominal speed of seizure of a new batch of products at the arrival of the input conveyor 4, while the sector 11 following the sector 12 is in the acceleration phase up to the transfer speed of its batch of bottles 40 to the disc 5, the sector 10 ends its hold phase of the bottles 40. Finally, as can be seen in figure 2c, sector 10 leaves its bottle hold phase and will be accelerated, while sector 12 begins its phase of asimi In the case of the first three bottles 40, as for the sector II, the disc 5 approaches with a speed sensibly identical to the latter and synchronized with the series 51 of cuts 54 of the disc 5, which will be presented with respect to said sector 11. The batches of bottles 40 thus formed are evacuated on the outlet conveyor 6 with a direction of displacement identical to that of the flow of the bottles arriving towards the device 1 on the input conveyor 4. If reference is now made to the figure 3 can be seen a device 1 associated with two other devices 1 arranged one next to the other with a constant side shift, this arrangement allows to form batches of bottles 40 that have many rows side by side. In this case the assembly of the device can comprise a common motorization to drive the shafts 2 of each device in order to obtain a number of identical products on all tracks and especially in batches, or separate engines to obtain batches of products 40 arranged in staggered, for example, that is creating a longitudinal phase shift of the rows of products 40 thus formed. The cuts made in sectors 10, 11, 12 can be made in removably mountable pieces at the end of said sectors, which advantageously allows the quantity of bottles in a batch of products 40 to be modified. In addition, another driving means can be considered. of the trees 2 as a cam device without departing from the scope of the invention. It will be readily understood that the device 1 can also serve to form a row of products 40 aligned against each other or at a short distance from a row of batches of products, the speed and acceleration parameters of sectors 10, 11, 12 as well as the phases of approach of the lots are modified accordingly.
