The floor of the needle 18 is communicated with the vacuum system 9. The piston 16 has grooves 20 for approaching and fixing the protrusions 14 of the support table and an axial hole 21 for the passage of the needle 8. Por-1 16 has cuts 22 located in the horizontal plane on both sides from its axis, and in notches 22 with the ability to interact with the lower knives 9 of the mechanism

Formations of transverse seams are installed; 23), having springs 24.

A stop 25 is fixed on the wall of the magazine 5 for fixing the needle 18. The device is also equipped with an ejector 26 and a device 27 for stopping the film in a certain position after cutting it.

All movable parts of the device (magazine 5, mechanism 7 for compressing articles with pig 16 and needle 18, knives 8 and 9, ejector 26) are driven using hydraulic actuator 28.

The device works as follows.

The pack of cash tickets 29 to be packed is manually laid with the box 6 of the product feeder on the support table fixed on the last part 12, the box 6 is closed and the pack 29 is placed on the part 13 of the support table with the other end. This protrusions 14 of the latter go into the grooves 20-16, and the product compression mechanism 7 is under the packaged pack 29 (Fig. 3). Then, by pressing the “Start (not shown)” button, the device is switched to automatic operation.

A magazine 5 with a box 6 and a bundle 29 of cash tickets placed on the parts 12 and 13 of the support table is fed up, the grippers 10 and extensions 11 are inside the sleeve, opened with the fitting 3. The grippers 10 press the sleeve against the walls of the shop 5, stretching the sleeve to a rectangular shape corresponding to the cross section of the subject to packing the pack 29 (Fig. 4).

Then, the mechanism 7 with porrnem 16 and needle 18 placed in lieM is fed up to a predetermined intermediate position (c |) ig. 5) so that when the store 5 is subsequently lowered, the pack of 29 packaged money is stopped by the piston 16 in a position that allows the knives 8 to freely close over the pack 29 (Fig. 7).

Magazines 5 with the grips fixed by the film 10 are fed down by the sleeve from the roll holder 1 (Fig. 6). The protrusions 14 of the support stand are free to go in the slots 20 of the port 16, and the pack 29 remains on the plane of the piston 16. When the magazine 5 moves downwards, the pack 29 enters the inside of the sleeve along with the piston 16 (Fig. 7). Then the luggage store 5 reaches its original position and stops. After stopping Magazine 5, the upper knives 8 come together and fold the sleeve over the pack 29, weld, the stamper - cut it off.

The film sleeve is reversed. The roll holder 1 is pulled up, stretched to a rectangular shape using the tool 3 to open the sleeve and stop at its original position. Mehm 1 meas 7 is fed up and squeezes inside package az1-pack 1 of the pack 29, pressing it against the flattened upper knives 8.

The clamps 23 allow to compress the packaged products evenly over the entire area and do not allow the ends of the products to hang over the piston 16 and further do not prevent the closing of the lower knives 9 under the pack 29 (Fig. 8). Upon reaching a predetermined density of the pack 29, the mechanism 7 with the needle 18 stops, and the lower knives 9 converge to an intermediate position at which they compress the clamps 23 of the piston 16 and partially intercept the pack 29 from below. In this case, the clamps 23 are not fully compressed (Figs. 7, 8 and 12).

The stop 25, placed on the inner wall of the store 5, fixes the needle 18 in a predetermined position. The mechanism 7 with the force 16, thanks to the spring-loaded clamps 23, freely emerges from the collapsed lower knives 9 and is lowered down to an intermediate position without disturbing the integrity of the sleeve film.

The needle 18 due to the stop 25 remains in place, and the spring 24 is compressed by the mechanism 7. The knives 9 continue to converge and completely clamp the film together with the needle 18 under the bundle 29 (Fig. 13). During the convergence of the lower knives 9, the stretchings 11 stretch the edges of the sleeve along the formed seam, eliminating the formation of bumps, and the upper knives 8 are completely divorced. The floor of the needle 18 after turning on the vacuum system allows air to be pumped out from the internal volume of the pack 29 in order to give it greater density.

At the end of the evacuation process, the stop 25 of the magazine 5 is triggered and the needle 18, due to the compressive force of the spring 24, is quickly removed from the pack 29 and the weld zone, the seam is welded and marked (Fig. 9).

The lower knives 9 are diluted to an intermediate cavity so that the packaged pack 29 is supported on them (Fig. IO). Ejector 26 removes the packaged stack 29 from the device and returns to its original position. At the same time, the mechanism 7 is lowered and opens the box 6, preparing the device for loading the next pack of 29 cash tickets. After that, the lower knives 9 are consumed completely (Fig. II).

The cycle of operation of the device ends there.

Thus, due to the clamps installed in the piston cutouts, when the lower welding knives are brought under the pack of cash money packs, the film is not firmly pressed to the compression mechanism piston and when the latter is pulled down, the film does not break because there is no friction between the piston walls and the lower welding knives . The integrity of the film is not broken. Packing quality is improved.
