MECHANISM FOR THE FORMATION OF THE GROUP PACKAGE OF THE AUTOMATIC PACKAGING MACHINE.

The proposed utility model relates to equipment for group packaging in shrink film of piece products, for example, empty and filled bottles, cans, household and perfumery and cosmetic products, pharmaceutical industry, etc.

A device for filling objects into a film according to a. from. USSR 973413 cells B65B 9/02, containing a supporting platform, a device for supporting the film, a mechanism for collecting and moving a group of objects, provided with a lifting and lowering wall, including a pusher made in the form of a movable plate, a device for welding the bag, and a mechanism for collecting and moving a group of objects is provided lifting and lowering wall located in the grooved hole of the support platform parallel to the plunger.

However, the location of the lifting-lowering wall in the groove of the support platform parallel to the plank of the pusher is applicable for grouping products with the pusher moving only one row. When grouping two or more rows of products to move

pusher, which dramatically increases the productivity of the packaging, it is not possible to infinitely adjust the width aisles for each of the stitched rows of different product ranges, which adversely affects the versatility of high-performance packaging machines, for example automatic ones, and reduces their applicability.

Known mechanisms for forming a group package of packaging machines in shrink film, in which the supporting platform is made in the form of a continuous sheet with holes in which the teeth of the combs are placed, which act as a lifting-lowering wall when composing rows of grouped products and put forward in the process of grouping by a special mechanism lifting and lowering, and then lowered by the mechanism before mixing; by grouping the grouped rows of products to the position of welding with a feed pusher with a bar. These mechanisms of forming a group package are also equipped with a cutter, which delays the supply of products to the working platform when the pusher is triggered.

Such mechanisms of forming a group package include, for example, an automatic zasovochny machine model AUM-12 manufactured by the closed joint-stock company STEKLOPAK Orel, Russia, (Service Manual

automatic packaging machine AUM-12, CJSC STEKLOPAK,

OrelD997.).

The loading mechanism for the formation of a group package of this packaging mapper can be carried out in several rows, which then, after lowering the teeth of the comb below the working surface of the platform, are moved with one movement of the pusher to the welding position, which dramatically increases the productivity of the packaging machine.

However, the design features of this packaging machine, along with the positive factor of increasing productivity, also do not allow the stepless adjustment of the width of the rows of dairy products to be cooked, which is necessary when changing the range of packaged products.

There is a known mechanism for the formation of a freight package of a packaging machine manufactured by KOTA LLC, Yaroslavl (Passport machine shrink MP 700-40-3.00.000. 1996, Yaroslavl) containing frame, pusher made in the form of a movable plate and mounted on the frame supporting platform made in the form of parallel jumpers made in the form of rotating rollers supported by the ends of the axes on the frame and located with gaps relative to each other and perpendicular to the pusher plate, lifting and lowering walls made in the form of a comb , The teeth of which are located in these gaps can be moved along them. 3

However, for automatic packaging machines operating at high speeds of moving packaged products, such as glass containers, this design of the support platform is not suitable, since the use of roller support platforms does not provide a sufficiently smooth working surface. In addition, the distance between the supporting surfaces of adjacent rollers is significant, and depends on their diameters, and with increasing diameters, the undulation of the working surface of the supporting platform increases.

These factors negatively affect the stability of the moved products in the process of forming a group package. Especially, for example, of such products with a small supporting surface of the bottom, a high center of gravity and having a large inertial tipping moment, such as some types of filled or empty glass bottles, perfumery products, etc.

As a result of the fall of, for example, bottles during the formation of the group, congestion occurs, the working cycle of the automatic packaging machine breaks, the productivity of the packaging decreases, and mechanisms can breakdown. The purpose of the invention is the elimination of these disadvantages.

This goal is achieved by the fact that each of the jumpers of the supporting platform is made of a rectangular profile, and the profiles

.

rigidly interconnected in the form of a monolithic lattice and mounted on the frame of the machine, for example, the upper surfaces of the Nrophilia are located in one plane.

The proposed utility model is illustrated by drawings.

In Fig.1 a section but aa in Fig.2 .;

In Fig.2 the mechanism for forming a group package, top view.

The proposed mechanism for the formation of a group package of a packaging mapon contains a frame 1, a supporting platform 2 with a working surface 3, guiding the combs 5 with teeth 4, a mechanism 6 for raising and lowering the combs 5, a plunger 7, a cutter 8, limiting the bead 9, rectangular profiles 10, gaps And between the rectangular profiles, the upper working surfaces 12 of the profiles 10, the feeding conveyor 13, 14 are packaging products (for example, bottles) and the end stop with sensors (not shown in Fig.)

The mechanism for forming a group package of a packaging machine operates as follows.

By conveyor 13, the products 14 (for example, bottles) in several rows enter the bead 9 located in the receiving part of the forming mechanism, preserving the row of products of the feed conveyor 13.

With further movement provided by the back-up of the products 14 with a movable feed conveyor, the products 14 move along the working surface 3 of the supporting platform 2.

The supporting platform is composed of separate upper surfaces 12 of rectangular profiles 10 lying strictly in the same plane of the working surface 3, which is ensured by a monolithic connection of rectangular profiles 10, with respect to the gaps 11, parallel to each other and perpendicular to the pusher bar 7 and is achieved when manufactured, for example, for due to the connection of rectangular profiles by welding and subsequent machining of the working surface 12.

The width of the passages between the teeth 4 of the combs 5 is set when preparing the packaging machine for operation, depending on the overall width of the packaged products, by moving the teeth 4 in the gaps 11 and fixing the combs 5.

At the moment of moving the products along the working surface 3, the guide combs 5 with the teeth 4 are raised by the lifting and lowering mechanism 6 into the gaps 11 of the supporting platform 3, and the pusher bar 7 is in the retracted position, which provides orientation and lateral stability to the rows of products filling the group package forming mechanism . As each row is filled, the products reach the final jniopa and act on the sensors 6

installed on each row (not shown in FIG.). After filling all the rows, the sensors give a signal to move the cutter 8, which stops the flow of products to the support platform.

The lifting and lowering mechanism 6 lowers the rows of guide teeth 4 downward, beyond the working surface 3 of the platform 2, and the plank of the pusher 7, moves the grouped rows of products to the welding position of the packaging machine (not shown in Fig.).

The pusher bar returns to its original position, the guide teeth 4 of the combs 5 rise up, the cutter moves to the position allowing the passage of products to the support platform, and the described cycle of operation of the group package formation mechanism is repeated.

The present invention provides high stability of products when they are moved in the mechanism of forming a group package, which makes it possible to increase the reliability and performance of the packaging machine.

In addition, the range of stepless adjustment of the width of the rows and the number of rows of grooved products increases, which expands the range of packaged products and, accordingly

the versatility of the packaging machine.
