(5) METHOD FOR PACKAGING PLANTS

one

The invention relates to packaging equipment, namely the packaging of a bottomless stack of piece goods into a sheath of synthetic heat shrinkable material.

There is a method of transport packaging piece goods, conclude-. This is due to the stacking of the objects, the coverage of the stack with a polymer film and the subsequent shrinking of the polymer film Cl.

The closest to the present invention is a method of packing piece objects, which involves stacking objects with the formation of ledges for fork gripping, covering the stack with at least two polymer shells and heat shrinking the last C 2 3

However, when applying the known methods, the position of small objects in the stack is reliable and stable, that. It leads to a violation of the orientation of the preme.trv..in the stack, damage to

stack and items and significantly reduces the performance and quality of stacking.

The aim of the invention is to increase the stability of objects in the stack.

This goal is achieved by the fact that when carrying out the method of packing piece objects,

the stacking of objects with the formation of ledges for forked grip, the covering of the stack with at least two polymer shells and the heat shrinkage of the latter, before

Claims (2)

By whitening objects are packed in groups into a polymer shell, and the stack is squeezed from all sides with its simultaneous cooling and formation of compounds between the surfaces of the polymer shells of objects, then the stack is covered with an outer polymer shell with the subsequent thermal shrinkage of the insulated cellular package. In this case, a distinctive feature is that, prior to heat treatment of pre-packaged groups of amiv, one sheath of objects, when they are stacked, is a layer of piles forming ledges on top and bottom, are lined crosswise with polymer ribbons, freely releasing their ends from four sides polymer shell The method is carried out as follows. The operation of stacking is carried out with heat treatment of pre-lumped groups into one film-wrapped objects with subsequent equalization, numbered squeezing of the stack from all sides with simultaneous cooling. and the formation of compounds between the surfaces of the film shells of the premeters, then the resulting stack is covered with an outer film shell with its subsequent heat shrinkage to form an isolated cellular package. In order to form a step before heat treatment of pre-packed groups into a single film shell of the stack, the stack of the stack forming the ledges is lined with top and bottom film tapes located crosswise, the ends of which are free from four sides and then fixed to the outer film shell. Example. Packs with synthetic detergents No. 18 according to GOST 17339 79 and weighing 1.5 kg in groups of 6 pieces are packaged in bdoki in one film package made of shrinkable polyethylene grade T film according to TU 6-05-051-79-7. Thickness of a film is 0,08-0,1 microns, width is 1000 mm. Block size: length 570 mm, width 285 mm, height 190 mm. Of the fourteen blocks make two packs. One package is made with a notch in the middle side for fork grab. In this case, the layer of the stack, forming a recess in which there are two blocks, is lined with top and bottom films with tapes of T film from shrinkable polyethylene grade T / 6-05-051-79-7 with a thickness of 0.15-0.2 microns. When forming a stack with a ledge in the lower part, the lower two blocks at the top and bottom are laid with film tapes. The ends of the bands loosely depressed on the four sides of the stack. Then a stack of blocks of objects is subjected to heat treatment (blowing with hot air at 150 C for (O from all sides with an air heater. Then the stack is uniformly compressed from all sides with a device with rotating plates and simultaneously cooled by a fan, blowing it with outside air at a temperature of for 20 s, with the formation of compounds between the surfaces of the film shells of the blocks. Then, the resulting stack is covered with an outer film sheath of T-shaped polyethylene film of T grade according to TU-6-05-051-79-7 with a thickness of 0.150, 2 microns with a perimeter of a sleeve of 3000 mm, with simultaneous corresponding bending up or down of the free edges of the tape.After putting on the film sheath, it is heat treated from an air heater at 210 ° C for 20 s on all sides. its fastening with the edges of film tapes, due to which an insulated package is formed with dimensions: height 6.95 m, width 0.8 m, length 0.6 1 weighing 126 kg. The proposed method ensures the stability of the items in the stack, the resulting stack is stable, the stacks are stacked securely one on top of the other, ensuring the safety of the items stored in them, which increases the efficiency and productivity of the stacking process. Claim 1. Method of packing piece goods, including stacking objects to form ledges for fork grab, covering a stack with at least two polymeric shells and heat shrinkage of the latter, characterized in that, in order to increase the stability of the items in the stack, the items are packed before stacking groups into the polymer shell, and the stack is squeezed from all sides with its simultaneous cooling and the formation of connections between 59868264 nrst mm polymeric shells of the pre-oto & miscellaneous, free release of their comtes, then the stack is covered outside with four sides, which polymeric sheath with post-bonded to the outer polymer shrinking it to form a shell, insulated cellular packaging. s Sources of information 2.
