(54) METHOD FOR INSTALLING BULK PRODUCTS IN ELASTIC MATERIALS

I

This invention relates to a technique for packaging loose products into elastic, for example film, materials, in particular, dusty synthetic materials.

Ieest of ways of packing sshuchnkh products in film materials, which consists in pressing the bulk material into a cruel state of manufacture in a tablet or briquette and its subsequent packaging in film material I 3

However, not all loose materials are packaged in film materials due to strong dusting, which makes it impossible to obtain subsequent high-quality welding of the seams, and when compressed, these materials are suitable for use, since their consumer properties vary.

There is a method of packing bulk products into a film, consisting in dispensing products in the form of a briquette with subsequent destruction of the briquette to

friable state after its sealing in f2 film.

However, the known method cannot be applied for packing such bulk materials as synthetic detergents, mineral fertilizers and the like, since these prefabs consist of granules that are destroyed after pressing and the product loses its consumer properties. .

ten

The closest to the invention to the technical essence is the method of packing the bulk products into elastic materials, which involves supplying the product to the package with the subsequent manufacture of its gcherlovina in vacuum 3,

But this method of packaging cannot be applied to the packaging of dusty granular products, as in the process of test - -.

The dry film material is dusty and the subsequent welding of the packing neck under vacuum does not allow one to obtain high quality packaging grit. In addition, when the bag is filled with product, the air in the bag prevents the product from passing through, forming an airlock. Therefore, the time to fill the bag increases, which reduces the productivity of the process. When vacuuming the filled package, it is impossible to ensure uniform and sufficient evacuation of the product in the package, since the outer layer of the product will prevent further evacuation of the inner layers, which does not allow to obtain a package of maximum density. The purpose of the invention is to increase the productivity of the process, the packing density and the quality of the weld. In order to achieve this goal, when using the method of packing the bulk products into elastic materials, providing for the supply of the product to the package with subsequent sealing of its neck in a vacuum, the dose of the product supplied is pre-vacuumed, and the supply to the package is performed in a vacuum-medium. In this case, the compression of the neck during the sealing process is carried out under atmospheric pressure. In the drawing, a device is shown in which the proposed method of packing active products into elastic materials is carried out. The device consists of a rectangular chamber I, on the bosom of which clamps 2 are installed for the neck of package 3. Chamber I has a flap 4 for closing the product. The chamber I with the devices is placed in an airtight container 5 Under the clips 2 there are installed jaws (not shown). Example I. Synthetic moksh means (CMC) of the OST6 type - 1 1O12 - 76 with a dose of ZOOO cm. Are put into the rectangular chamber I, on which the package 3 of plastic plastic 240 mm (240 mm wide) is worn empty. The shutter 4 closes the opening of the chamber t so that the product will randomly fit into the package. The clips 2 hold the package 3. At the base of the chamber 1, with a gap from it, there is an interfering welding thermopulse sponge. Chamber I with devices is tagged into an airtight container 5, from which air is evacuated by a vacuum pump, which creates a vacuum of up to 14O160 mm Hg. Art. Then the flap 4 is opened, and the product without dusting is poured into the packing 3. The clamps 2 open 8 74, and the package 3 with the product lowers chamber I to the bottom of the container 5, the neck of the package 3 is brewed with thermo-impulse slug, the capacity 5 is connected with the atmosphere. At the same time, the atmospheric pressure (which corresponded to 724 mm Hg. Art.) Compresses the package with the product to such an extent that a rigid flat-shaped briquette is obtained. Next, the briquettes are grouped with 6 pieces each and wrapped in a shrink film. Such a unit, when it is being transported, behaves similarly to rigid piece objects. With a punctured puncture of a separate package, which corresponds to the opening of the package by the consumer, the product in it acquires the initial properties, i.e. becomes loose without lumps and joints. Example 2. Cleaner for household items Pemok-Salt - OST6 type cleaning powder abrasive type OST6 - 15 - 39O - 75 with a basic density of 0.85 g / cm and 2.5% humidity with a dose of 100O cm poured into polyethylene Packing 3 with a width of 24 mm and a height of 12 mm. The suction is carried out in chamber I having a shutter 4 for the product. Chamber I with devices is placed in an airtight container 5, from which air is sucked off with a vacuum pump, creating a vacuum of 14-160 mm Hg. Next, the flap 4 is opened, the product without dusting is poured into the package 3, the clips 2 are opened, and the package 3 with the product is lowered from the chamber I to the bottom of the container 5. The neck of the package 3 is brewed with a thermo-pulse sponge and the container is connected to the atmosphere. At the same time, the atmospheric pressure (726 mm Hg) compresses the package 3 with the product to such an extent that it becomes a rigid flat briquette. The product in the package after opening acquires its original properties. Example 3. Systematic detergent (CMC) of the OST6 Lotus type. 15-1012-76 with a dose of 3000 cm is placed in chamber I, on which package 3 of polyethylene film (GOST 1O35473) 24 O mm wide and 42 O mm long is empty. Chamber I with devices will be placed in an airtight container 5, from which air is drawn off by a vacuum pump, creating a vacuum of 14 O-16 O mm Hg. Next, the flap 4 is opened, and the product, without dust, is inserted into the package 3, the clips 2 are opened, and the package 3 with the product

It is lowered from chamber I to the bottom of container 5. CAPACITY 5 is connected with atmospheric pressure (726 mm Hg). Atmospheric pressure compresses the package with the product and seals (compresses) the neck of package 3 to such an extent that the resulting briquette is maintained for 8-10 hours without destruction. The obtained hard-form briquette reliably retains its rigidity and allows stacking and various handling operations to be carried out with it.

Then the packing neck is welded with a thermopulse sponge outside the vacuum chamber.
