The invention relates to packaging methods and is intended primarily for the packaging of a bottomless stack of pieces.

The purpose of the invention is to increase productivity by simplifying the formation of a stack of piece objects. i Fig. I shows a device for the packaging of a flat pile of piece objects, a general view; on) 2 - the sequence of forming objects; in fig. 3 - the sequence of the formation of a stack on the film of the bottom row of objects of the stack; in fig. 4 - control device, general view.

A device for carrying out displacements (; both contains mechanisms 1 and 2 of the group) and coating with a film of 3 rows U of items 5, stack 6, heat-shrinkable oven 7, -grab-manipulator, 8, and unloading container 9.

The grouping mechanism J has a pusher 10 and a cam 11, which acts on the crossbar 12 of the counter I3 11BOW 4 items 5, the Crossbar 12 g drives the disk 14 with the control pen 15 control, on which the projections 16 and 17 are fixed control of the closing of welding-cutting transverse knives 20 and longitudinal knives 21 g tools 22 welding-pieces g foam 3 row 4 items 5 headquarters | 6

The discharge conveyor 9 is equipped with a device of 23 innings: and films 24 under the bottom row of 4 items 5 piles of 6

and a device 25 for welding it to the base 26 and the steps 27 of the stack 6,

The method is carried out as follows.

I After pushing each row of 4 parameters 5, the pusher 10 through the kula-11 sets in motion the crossbar 12 of the counter 13 rows of 4 objects 5 which turns the disk 14 of the control device 15 into steps. The input (not shown) between the cross-Qij and the disk 14 is made in such a way ()) m that the disk 14 makes a complete rotation of the required number of p - d (& 4 items 5 to form the formula,

After one set of several REEDs is set up 4 items 5, the protrusions 16 mounted on the disk 14 click on ddtchik 18, which includes)

cross 20 and longitudinal 21 knives. The knives 20 and 21 are closed and, forming longitudinal 28 and transverse 29 welding seams, cover a row of 4 items 5 or several rows 4 with a film 3, not a division of the packed items 5 from the film web. After dialing the last row of 4 horizontal layers, the projections 16 and 17 act on the sensors 18 and 19, which include the closing of the knives 20 and 21.

The finished row 4, which is a chain of objects 5 packed and interconnected by film 3, is fed to the heat-shrinking furnace 7, where the film 3 is heat-shrinked, after which the gripper 8 places it on the discharge conveyor 9.

Before laying the first row 4-, which is formed with an incomplete number of items to be packaged compared to the subsequent one, the film 24 is fed to the unloading conveyor 9 by means of the device 23 under the lower row 4 of items 5 of the stack 6. After the second row 4 is laid down by the device 25, the film web 24 welded to base and ledges of stack 6.

After the last, top, row 4, stack has been laid, the stack 6 is moved by the unloading conveyor 9 for further transportation with the help of forklifts or other lifting mechanisms.

Thus, the proposed method and apparatus for its implementation allows to simplify the formation of a stack of piece objects, resulting in a performance increase.

Claims (2)

1. A method of packing a bottomless stack of piece goods, consisting in stacking objects packed in a plastic film to form ledges for a forklift, characterized in that, p. In order to increase productivity, before stacking, each group of objects is packed by welding from three sides, not a section of the film web before forming a full horizontal layer of the stack, but when the stackers are formed, the first layer is placed on the film sheet with an incomplete number of formed groups of objects in comparison with the subsequent ones, after which the film sheet is welded to the base and ledges of the stack. 2. A device for packing a bottomless stack of piece objects, containing mechanisms for grouping and covering with a film of a series of objects in a stack, a heat-shrinkable furnace, a gripper-manipulator and an unloading conveyor, characterized in that it is equipped with control devices to increase productivity. the process of feeding the film under the bottom row of objects of the stack, welding the film segments of the row of objects of the stack and welding the film of the lower row of objects to the base and ledges of the stack with sensors, while the group number counter of rows of objects is mounted in the grouping mechanism, and the control device is made in the form of a disk with protrusions with the possibility of interaction with counters of the number of rows of objects and sensors of welding-segment devices and welding. sriе.2 Dzig.Z fffua4
