Abstract

The invention relates to a packaging technique, in particular, to methods for packaging a bottomless stack of piece goods. The aim of the invention is to reduce energy consumption and simplify the packaging process. Pieces 2 are stacked in stack 1 to form ledges for the forked grip in the upper layer, then the stack is covered with the first film cover 5. The film-covered stack 1 is wrapped with thread 9 to form the ledges for the forked grip. The stack 1 is turned over 180 ° and the second film shell 5 is put on it so that its edges overlap the edges of the first shell 5. After that, the polymer film-covered stack 1 is spirally wrapped with thread 9. The end of the thread 9 is fixed on the surface of the package. When wrapping the thread, the piece objects 2 are compacted in the stack 1 and the polymer film fits tightly on the surface of the stack 1, while eliminating the heat shrinking operation. 2 hp ff. 6 Il.

The invention relates to a packaging technique, and specifically to a method for packing a bottomless stack of piece objects.

The aim of the invention is to reduce energy consumption and simplify the packaging process.

The method is as follows.

Pieces are placed in a staple with the formation of forks in the upper layer, then (the table is covered with a film cover. Covered with film. The scale is wrapped with thread, the film is fixed on the head and the steps form under the forked hook. Then the pile is turned 180 ° and they cover it with a second film jacket. After that, the stack is spirally wrapped with a thread. For a more dense fixation of the film and skreleni the stack, it is advisable after turning it on the 180s in the upper part of the stack

stupid, and the thread run out of elastic

material:

The drawing shows a device implementing the proposed method. FIG. 1 shows a device for packaging a bottomless stack of piece goods, a general view; in fig. 2 and 3 a piling device; in FIG. L, the packaging of a bottomless stack of a sheet-like polymeric material; in fig. 5 and 6, the package is held together to form ledges at the top and bottom of the stack.

A device for packing a bottomless stack 1 of piece goods 2 comprises a conveyor 3 connecting device 4 for applying film cover 5 to stack 1, device 6 containing the carrier 7 and rolling roller 8 for winding thread 9, and tilter 10 for turning the pile 1 piece ny objects 2 180 °.

A device for carrying out the proposed method works as follows.

Items 2 are stacked to form ledges in the upper layer for fork locking (Fig. 1, position A). Then the stack 1 by the conveyor 3 is fed into the device k, in pieces, breaking it and fixing it on the stack, covered with a film shell 5 with a torus (Fig. 1, item B). After that, the stack is fed into the device 6 "

After the formation of the ledges, the pieces 1 are fed into the tilter 10, and the cat is turned over by a 180 ° ledge downwards (Fig. 1, position D). Transport 3 stack 1 is placed in the arrangement k for putting on the second film of the shell 5. This shell is put on its edges overlapping the edges of the shell per shell 5. Then the stack is placed in the device 6, in which, changing the angle of the carrier, 7 is wrapped in a spiral-shaped polymer the sheath 5 is stacked 9. After the winding 9 is completed, the thread 9 is cut and its end is covered, for example, under the thread on the stack 1. The thread 9 can be made of elastic material for sealing rod 1.

In order to firmly fix the labor of piecework, it is necessary to form figuratively ledges in the base and lower parts of stack 1, and thread the thread 9 on the ledges along the diagonal of front g of stack 1.

The proposed method allows the use of the Thermus operation to reduce the energy consumption, simplify the steps of forming the ledges and putting up the stack, and use more cheap polymeric materials.

Claims (3)

1. The method of packing an empty stack of piece objects, stacking objects in the upper part of the stack of blunt pods under a forked grip, piled on the stack of the first film shell to its fixation on the stack, forming ledges, turning the stack on 180 characterized by the fact that, with reduced energy consumption and simplified packaging, fixing 0 0 five thirty 35 40 55 breaking and fixing it on the stack, 45 50 the carrier 7 is set at a desired angle, the rolling roller 8 is guided to the step of stack 1, the free end of thread 9 is attached to stack 1, for example, with adhesive tape. The rotation of the carrier 7 winds up at least one turn of the thread 9 to form the first step under the forked grip and fix the sheath 5 on the stack 1. The second step is formed similarly. After the ledges are formed, the stack 1 is fed to the tilter 10, in which it is turned 180 ° downwards (Fig. 1, item D). The conveyor 3 piles 1 into a device k for putting on the second film casing 5. This casing is put on so that its edges overlap the edges of the first casing 5. Then the piling is placed into the device 6, in which, gradually changing the angle of the carrier 7, the coated polymer is wrapped spiral sheath 5, stack 1 with thread 9. After winding is completed, thread 9 is cut and its end is fixed, for example, under thread of thread 9 on stack 1. Thread 9 of elastic material can be used to seal stack 1. In order to firmly fasten difficult-to-put piece objects, it is advisable to form the ledges in the upper and lower parts of the stack 1, and winding the thread 9 through these ledges along the diagonal of the front face of the stack 1. The proposed method makes it possible, by eliminating the heat shrinking operation, to reduce energy consumption, simplify the steps of forming the steps and packing the pile, and use cheaper polymeric materials. Invention Formula 1. A method of packing a bottomless stack of piece objects, including stacking objects, forming ledges under the forked grip in the upper part of the stack, placing the first film cover on the stack, fixing it on the stack, forming a ledge, turning the pile 180, applying the second film film to it. the fact that, in order to reduce energy consumption and simplify the packaging process, on the stack of film shells and the formation of ledges produced by wrapping the stack of thread. 2. The method according to claim 1, characterized in that after turning a stack of 180 ° in its upper part form additional ledges. 3. A method according to claim, characterized in that the thread is made of an elastic material. fig .. FI.3
