The aim of the invention is to increase production. efficiency and reliability of operation. In a multi-tray tray 1, the product 9 is fed to rotating disks 4 arranged in russes on a vertical shaft. Then, through the channels formed by the guides 5 and the inner rim 15, the products fall into the pockets of the groove formed by the figured notch in the sprockets 8 and adjacent disks of the receiving unit. Upon filling the vertical row of products, the sprockets 8 turn and the products successively occupy the positions a, b, c, d, e, f, h. A window for unloading the foot with a flap 10 is located at the last position in the housing 6.

The invention relates to devices for grouping a certain number of piece goods and supplying them, for example, to packaging, and can be used in the food, chemical, pharmaceutical and other industries.

The purpose of the invention is to improve the performance and reliability of the device by combining in-time and money-feeding operations, normalizing the vertical row, grouping products on each other and unloading the formed foot, as well as increasing the rigidity of the whole structure and eliminating inertial oscillations during repetition stepping movements.

FIG. 1 shows a device for a set of piece goods in a stack, section J in FIG. 2 is the same, partially cut away plan view; FIG. 3 shows section A-A in FIG. 2

A device for a set of piece products in a stack contains a multi-thread feeding tray 1, provided with a gate 2 for controlling the number of products in the stack, a drive with a drive (not shown) consisting of receiving and forming units. The receiving unit is designed as mounted on a vertical shaft 3 for rotation of parallel discs 4 with spring-loaded guides 5, each of which is located at the level of the corresponding stream of the feeding tray 1.

The forming unit includes a vertical cylindrical body 6 with a window for entry of the disks 4 of the receiving unit. On the inner surface of the casing, they are fixed in the planes of the respective disks 4 of the receiving unit of the shelf 7. In the form of open rings, the length of which increases by an equal amount of top down and equal to the step length of the sprocket 8 multiplied by the number n-1, where ti is products 9 above the shelf and grouped in a vertical row.

At the level of the output end of the lower shelf in the side surface of the housing 6, a window is made for unloading the feet with the flap 10. Inside the housing 6 between the shelves 7, are fixed on the hollow vertical shaft 11 with the possibility of periodic rotation by means of a Maltese mechanism

12 sprockets 8 for forming and moving the stop of products 9. The Maltese gear 12 receives movement from a pair of gears 13 and a clutch 14.

The device works as follows.

Products 9 are fed along a multi-tray tray 1 by a feed mechanism (not shown) or in continuous streams along streams to parallel, continuously rotating discs 4 of the receiving unit. Further, through the channels formed by the guides 5 and the inner rim of the discs 15, the products pop into the pockets of the groove c (where the grouped vertical row is formed. The pocket is a cell formed by adjacent discs of the receiving unit and the surface of the figured cut-out of the asterisk 8.

If the vertical p d is full, i.e. the pockets of the receiving unit are filled with items 9, then the sensor 14 and the actuator (not 25 are shown) turn on the sleeve 14, which by means of the Maltese mechanism 12 turns the forming unit one sprocket. Products 9. from the position of the groove and the teeth of the sprockets 8 are moved to the position of the groove fc on the parallel flanges 7. As for the top product 9, the construction of the shelf 7 is not provided, it lies directly on the downstream, i.e. at the first rotation of the forming unit one step in the position of the groove b, the two upper products are grouped one on another - the rest are separated from each other by shelves 7.

When re-filling the grooves with 9 pockets and the sensor signal, the Maltese mechanism 12 is triggered and rotates the forming unit to the next step. Those products 9 that were in the position of the groove b are moved to the position of the groove c, and the two earlier grouped top products, as the shelf below them ends, lie directly on the third, downstream product. In this vertical row of the groove c. There are three grouped products, yet the rest are disconnected and located one above the other on the shelves 7. The same unit repeater in the groove b position moves the products from the groove pockets a, and two

When re-filling the grooves with 9 pockets and the sensor signal, the Maltese mechanism 12 is triggered and rotates the forming unit to the next step. Those products 9 that were in the position of the groove b are moved to the position of the groove c, and the two earlier grouped top products, as the shelf below them ends, lie directly on the third, downstream product. In this vertical row of the groove c. There are three grouped products, yet the rest are disconnected and located one above the other on the shelves 7. The same unit repeater in the groove b position moves the products from the groove pockets a, and two

the top products are grouped.

The grouping of the indicated stack with the further movement of the vertical row of articles into the positions of the slots d, e continues in a similar order. When the stack of products is in the position of the groove f-, it will be fully grouped. At the next rotation of the forming unit, the ready stack of products is moved to the position of the groove h, from where it goes to the packaging.

Depending on the packing method, the unloading of the formed stops is possible in three directions: both through the window provided in the housing 6 and along the axis of the groove h - up or down

When products are fed in continuous flows along the multi-lumen tray 1 and, the spring-loaded guide 5 straightens the moving products 9 by means of streams and, when the unit is turned, eliminates their jamming. The presence of a pair of gears 13 in the drive chain of the forming unit allows flexibility in varying the performance of the device depending on the rotational speed of the receiving unit, since for one revolution of the coupling 14 the forming unit groups and increases one stack of grouped items.

To regulate the number of items in the stack, the multi-feed tray 1 has a flap 2, which overlaps the corresponding number of streams of the tray. Depending on the material and shape of the grouped products, the disks 4 of the receiving unit can be made of various materials. . Their working surfaces have coatings j providing the corresponding

coefficient of friction between the surfaces of the product and the disks.
