Abstract

The invention relates to a technique of packaging transport packages in a film jacket. The purpose of the invention is to simplify the design and reduce energy consumption. The device for putting on a sleeve of shrinkable film on the transport package contains frame 1, roll holder 2, guide and drive rollers 3 and 4, mechanisms 5 for opening the sleeve, mechanism 6 for cutting the sleeve, mechanism 7 for forming a transverse seam, mechanism 8 for pulling the sleeve on the package and the mechanism 9 of the package. Each mechanism 5 includes pivot rods 12 mounted on a horizontal shaft 13 by means of an articulated parallelogram 14. The clamping elements 15 are also mounted on the shaft 13. Each rod 12 and a row of clamping element 15 are positioned to form a gap for the sleeve film to pass through. is provided by means of the stop 16. 2 Il.

Description

 The invention relates to a technique of packing a transport package h film sheath

The circuit of the invention is the simplification of the hops and reduction of energy costs.

Fig. 01 shows the device in the initial position; nz fig „2 the same l oment raskozyzanie sleeves ,.

The device for putting on sleeves chz heat shrinkable captivity to trans. ™ pozdny gzget contains a frame, roll holder 2, flat ball and drive axes 3 and 4, mechanisms 5 for opening the sleeve, mechanism 6 for cutting the sleeve, mechanism 7 for forming a cross seam mechanism 8 for pulling the sleeve onto the bag and bag feeding mechanism 9. Mechanisms 5 for opening the sleeve are mounted with the possibility of reciprocating movement in a vertical plane inside frame J from two sides in the area of folded sleeve edges by, for example, 9 endless chains 10. driven by rotation But each mechanism 5 includes swivel rods 12 mounted on horizontal shaft 13 by means of a hinged paraplelogram 14, and clamping elements 15 "also mounted on the shaft 13"

Each rod 12 and adjacently placed pressure element 15 are arranged to form a gap and between each other the passage of the film passage of the sleeve 0. The gap q in the initial position is provided by means of the stop 56

When the mechanism 5 moves downward, the hinge 17 is fixed by the stop 18 "Jari eto hinge parallelogram 14 flies s and the rods 12 rotate, opened the sleeve" After moving the rod 12 by the gap size and it touches the clamping element 15o Then they move together, and between them there is a film

The device works as follows

A roll with tubular film is placed in the roll / holder of the 20 sleeve hose through the guide and drive rollers 3 to 4 and lowers below the mechanisms 6 and 7 ° B in the initial position of the rod 12 in close proximity to the sleeve removal mechanism 6, and the edges film folds in the gap between the rod 12 and the clamping element 150 B of the lower part on the feed mechanism 9 a transport package is installed0 Mechanism 8 for pulling the sleeve on the bag is in the bottom position

The drive of the rollers 4 is turned on and the sleeve is supplied to a predetermined level. After that, the drive 11 is moved by the mechanism 5 for opening the sleeve. After full rotation of the rods 12, the mechanism 8 is pulled up to pull the sleeve onto the bag, its pins enter the sleeve and rotate so that the sleeve is evenly tensioned between them. The rods 12 rise to their original position. In doing so, they fold, remaining all the time between the folds of the sleeve. The edges of the folds are located in the gap a between the rod 12. and the clamping element 15. After this, the transverse seam of the cut sleeve is cut and welded, and the mechanism 8 is lowered until the dashboard is fully tensioned onto the bag0 The pins come out of contact with the film . The covered package is removed from the frame 1. The new package is fed there, the cycle is repeated.

The use of the proposed device in comparison with the known 5

51578

It is easy to simplify the mechanism for opening the sleeve and reduce the energy consumption for its drive, since the known device uses rather complex gripping devices in the form of double transport cures, which require additional drives, stabilization of the velocity, le, t, control of the grip of each edge, g. also turn-JQ levers with their drives, which leads to the complexity of manufacturing, increased requirements for commissioning, s also increase in weight and installed capacity
