Description

MECHANISM FOR THE FORMATION OF THE PEAR STICKER OF THE AUTOMATIC TRAINING MACHINE.

The proposed utility model relates to equipment for group packaging of piece goods, bottles, cans, household and perfumery cosmetics, pharmaceuticals, etc. in film, for example, in shrink.

There are devices for packing objects into film containing: a mechanism for forming a group package, a working table with a transverse window, a device for two rolls of film, a device for forming transverse seams, a weld sponge and a pressure sponge located in the transverse window of the table.

Widely known devices in which d.11ya tightening a group of products, in order to obtain a denser package, shrink film is used.

These devices further comprise a feed conveyor passing through a shrink tunnel in which the shrink film wrapping around the bundled package is heated and, after cooling, is seated.

An example of known devices are, for example, the device of a. from. USSR 973413 cells 65 В 9/02 “A device for packing piece objects in film and devices manufactured by TERMOPAK Poland (Prospectus from TERMOPAK Poland at the ROSUPAK exhibition 1997, Moscow, Sokolniki Exhibition Center, 19.06.97).

The mechanism for forming a group package of known devices for packaging piece products in heat-shrink film consists of a support platform, the working surface of which is made with a slit hole, in which movable guides are placed, made with the possibility of raising and lowering the working surface of the support platform, movable guides located in the slotted holes and designed to increase the stability and orientation of the packaged products, the cutter located on the supply side of the products, thick STUDIO grouped articles bounding sides and the abutment.

However, the continuous surface of the support platform of known mechanisms for forming a group package, for example, of the well-known company TERMOPAK Poland, is made of sheet steel with a sliding friction coefficient of 0.15–0.18, which, when operating at high loading speeds of the formation mechanism by the feed conveyor, automatic packaging machines is a factor

determining insufficiently good sliding of the packaged products on the platform, which in turn adversely affects the stability of some types of packaged products. For example, such products with a small supporting bottom surface, a high center of gravity and having a large inertial tipping moment, such as filled PET bottles, perfumery products, etc.

As a result of the fall of, for example, PET bottles during the formation of the group, congestion occurs, the duty cycle of the automatic packaging machine is disrupted, the productivity of the packaging is reduced, and mechanism breakdowns can occur. The purpose of the proposed utility model is the elimination of this drawback.

This goal is achieved by the fact that the working surface of the supporting platform is made of material with a coefficient of sliding friction without lubrication not higher than 0.08.

Figure 1 shows the proposed mechanism for forming a group package, side view;

Figure 2 shows the same mechanism, a top view.

The mechanism for forming a group package contains a support platform 1 with a working surface 2, slotted holes 3, movable guide 4, a mechanism for raising and lowering the movable 3

guides 5, pusher 6, cutter 7, bounding sides 8,

installed at the junction of the feed conveyor, stop 9,

10-feed conveyor, 11-packaged items (e.g. PET bottles).

The described mechanism for the formation of the cargo package works

in the following way:

According to the feed conveyor 10, the packaged products 11 (for example, PET bottles) arrive in several rows in the bounding sides 8 located in the receiving part of the mechanism, preserving the row of the products of the feed conveyor 10. With further movement provided by the support of the products by the conveyed feed conveyor, the products 11 move on the working surface 2 of the supporting platform 1.

The working surface of the platform. made of material with a coefficient of sliding friction without lubrication not more than 0.08. For example, fluoroplastic, which provides stable movement from the feed conveyor 10 to the group bag formation mechanism and reliable movement inside of such products with a small supporting bottom surface, a high center of gravity and having a large inertial tipping moment, such as filled PET bottles, perfumery and cosmetic products etc.

CITY. (| € (0 4

At the moment of moving the articles along the working surface 2 during the loading process, the movable guides 4 are lifted by the lifting mechanism 5 into the slotted holes 3 of the support platform 1, and the pusher 6 is in the retracted position and also serves as a guide, which provides orientation and lateral stability to the rows of products filling the mechanism the formation of the cargo package. As each row of products is filled, the products reach the stop 9 and act on the sensors installed on each row (not shown in Fig.). After filling all the rows, the sensors give a signal to the actuators to move the cutter 7, which stops the flow of products into the mechanism for forming the cargo package.

Then, the raising and lowering mechanism 5 lowers the movable guides 4 behind the working surface 2 of the platform 1, and the pusher 6 moves the grouped products to the welding position of the packaging machine and returns to its original retracted position. Then the cutter also returns to its original position and allows the products to fill the mechanism for forming a group package for picking the next group.

The described cycle of work is repeated. The proposed utility model of the formation of group

the package provides good stability of products even with a high center of gravity and a small supporting surface of the bottom, for example, such as PET bottles, products of the perfumery and cosmetics industry, etc., which makes it possible to increase the reliability and performance of the packaging machine.
