Description

one

The invention relates to packaging, ring-shaped products, namely, wrapping them with a metal tape, and can be used in various sectors of the national economy, in particular, in the tire industry when wrapping tire packages.

A device for tying ring-shaped products is known, which contains a wire feed and fastening mechanism, 10 locks, a drum with channels and a rotary plate, and lifting and lowering pressure levers with jaws for tied bays p. .

The disadvantage of this device is the complexity of the pressing unit, its cumbersomeness and the impossibility of uniformly pressing the package over the entire plane.

The aim of the invention is to eliminate these drawbacks.

The goal is achieved by the fact that the drum contains an inner cylinder located inside it, the rod of which is provided with longitudinal ribs, 25 extruded in the form of inclined guides interconnected with a clamp, and a longitudinal groove is formed on the lateral surface of the drum: In addition, the longitudinal re-

sconce brackets contact inner

the drum surface.

FIG. 1 shows the device, a general view; - FIG. 2 — node 1 in FIG. one; in fig. 3 is a view A of FIG. 2; in fig. 4 is a view B in FIG. 2

The wrapping device comprises a tape-feeding device 1, which interacts with the mechanism 2 for fastening and cutting the tape, forming a panel 3 of the mechanisms mounted on the frame 4 of the device. On the panel 3 of the mechanisms, a movable frame 5 and a movable frame 6 are mounted, moving with the aid of a ram 7 mounted on the panel 3 mechanisms. The frames contain channels 8 and 9 directed to the engine and interact with the drum 10 mounted on the frame 4 and containing grooves 11. Rotating

: The drum 10 is made with an internal ram cylinder, the rod 12 of which contains longitudinal ribs 13 with inclined guide grooves 14, which engages clamp 15 and ledges 16, contacts with drum shell 17 and clamp 15. Clamp 15 contacts with pa, Oom 18 of the shell 17 and interacts with the wedge 19. Wedge ledge 19 interacts with the clamp 15 and the inner groove 20 of the ribs 13.

The operation of the device is as follows.

The movable frame 6 is in the open position, the package of ring-shaped objects 21 is put on the drum 10, the inner power cylinder of the drum is actuated, moving the rod 12. The clamp 15, interacting with the wedge 19, moves along the grooves 14, and the ledge 19 enters the groove 20. Moving, the clamp 15 compresses the pack 21 to the desired value. The movable frame 6 is lowered to form a continuous channel from the mechanism panel 3 and the fixed frame 5. A power drive (not shown) of the tape feed device 1 is activated, which feeds the tape 22 through the closed channel around the bag 21 as soon as the front end of the tape 22 enters the lock zone , the tape feed mechanism stops, then the front end of the tape is clamped. In the mechanism panel 3, the tape feed mechanism is reversed and the tape leaves channels 8.9 and groove 11, making the package 21 tight, and the feed mechanism reverses and the tape 1, and the mechanism 2 for fastening and cutting the tape performs the operation of forming the lock and its cut. The power cylinder 7 of the movable frame b is turned on, raising it to the upper position, a stepping drive (not shown) of the bar, bang 10 is turned on, turning it at a predetermined angle in which another groove of the drum 10 is located and the process is repeated to the required amount of bag.

Upon termination of the binding, the internal power cylinder of the drum 10 is actuated, moving the rod 12 to the initial position. The clamp 15, which is located in the grooves 14 of the ribs 13 and the groove 18 of the shell 17, moves to the end of the groove 18 and begins to descend through the groove 14 to its original position, freeing the bag 21. The bundled bag is removed from the drum of the machine.

The process then repeats.

This device allows us to simplify the design, reduce the size and intensity, and increase the reliability of bag pressing on the tying drum, which will give a positive economic effect.

Claims (2)

1. A device for ringing ring-shaped objects, mainly pneumatic tires tires, containing a reel-clamp for ring-shaped objects, which is so that, in order to ensure more uniform compression of ring-shaped objects, a power cylinder is mounted inside the drum , on the rod of which there are fixed longitudinal ribs with inclined guides, while a longitudinal groove is formed on the lateral surface of the drum, and the clamp is located in this groove and mounted on inclined guides. 2. The device under item 1 ,. This is due to the fact that the longitudinal ribs of the rod are connected to the inner surface of the drum.
