Abstract

The invention relates to a method of packing items, can be used in the chemical, food and other industries and is aimed at simplifying the method. The stack of objects is covered with a film jacket and heat treated. Then, on the upper surface, at the side walls of the stack, embedded elements are placed, covered with a film sheet, which is fastened with the ends with a film cover, and heat treated, forming channels under the forked grip. The formation of a channel for fork grip on the upper surface of the stack simplifies the packing method, since there is no need to make grooves for the fork grip in the head plate itself, which requires sophisticated equipment and high energy costs. In addition, the cargo handling process of the stack is simplified, its stability is enhanced, since the center of gravity lies below that: the check of its capture, and consequently, the possible drop of the stack is eliminated. 3 il. i (/

The invention relates to the packaging of a bottomless stack of piece objects in a shrink film, can be used in the chemical and food industries.

The aim of the invention is the expansion of technological capabilities.

FIG. Figure 1 shows the technological sequence of covering the stack with a film sheet and forming channels under the forked grip; in fig. 2 — node I in FIG. one; in fig. 3 - node II in FIG. one.

The method is carried out as follows.

Objects are placed in layers in layers, covered in stack 1 with film sheath 2, which is then heat treated. As a result, the shell 2 shrinks tightly covering the stack 1. Then, on the upper surface 3 of the stack 1, at its side walls 4, the embedded elements 5 are made of non-rigid material (at least two) and covered with the stack with 1 film sheet 6 (or intersecting tapes 7), the ends of which are fastened with the film shell 2 on the upper surface of the stack 1 and on the side walls 4, for example, heat seal and heat treat the film web 6. At the same time, the embedded elements 5 are wrapped around the sit down film web 6 and form 8 channels with a forklift. The embedded elements 5 are then removed from channels 8 (but they can also be left in channels 8).

Example. The method of packing items tested with the following sequence of operations.

Bundles of 208 mm in size, respectively, in width, thickness to height, filled with synthetic detergents with a filling volume factor of 0.85 pack and weighing 0.4 kg, are placed in layers in stack 1. Then stack 1 is covered with shell 2 of polyethylene shrink film 0.1 m and subjected to heat treatment (blowing with hot air) at 200 ° C for 6 minutes from all sides with an air heater.

neither the film under the action of the surrounding medium: - its shrinkage occurs with tight fit of the outer surface of the stack 1. Then on the upper surface 3 of the stack 1 at its opposite side walls 4 are laid mortgage elements 5, which are used as blanks packaged packs and stack 1 covered with a canvas 6 of polyethylene shrink film with a thickness of 0.15 mm. After that, the film sheet 6 is fixed with the shell 2 at the top and along the side walls 4 of the stack 1, and then subjected to heat treatment: blow the canvas with hot air for 2.5 minutes. After cooling the film web 6 under the action of the environment, it shrinks with a tight fit of the embedded elements 5 and the formation of the channels 8 under the fork grab.

The formation of channels under the forked grip on the upper surface of the stack allows for a simplified packing method, since there is no need for making notches — for the forked grip at the headquarters itself, which requires special complex devices and high energy costs.

In addition, the cargo handling process of the stack is simplified, its stability increases, since the center of gravity lies below its pick-up points and, consequently, the possible fall of the stack is eliminated.
