Abstract

The invention relates to packaging, in particular to packaging of rolled materials, and can be used in light industry. The purpose of the invention is to improve the quality of packaging. The device contains a roller table 1, the rollers 6 of which are inclined at an angle α = 20-70 ° to the horizontal plane, a chain conveyor 4 with pushers 9 and a mandrel 3 of cylindrical shape mounted on the roller table 1. The mandrel 3 has longitudinal notches 10 in the wall for dialing the packaging material 8 and the cutout 11 for the passage of the pushers 9. On the outer surface of the mandrel 3, a spring-loaded clamp 17 is attached, provided with a roller 19 at the end. Tight wrapping of the packaging material 8 of the roll 2 when pushing it through the mandrel 3 improves the quality packaging and improve the presentation of the packaging. 1 hp ff, 6 ill.

Description

The invention relates to packaging, in particular to packaging of rolled textile products, and can be used in light industry.

The aim of the invention is to improve the quality of the packaging.

FIG. A device for packaging rolled materials of general quality is presented; in fig. 2 shows section A-A in FIG. one; in fig. 3 - a device for packaging, side view at the time of putting on the mandrel and sealing the end of the packaging material; in fig. 4 - the same, at the time of submission of the roll; in fig. 5 is the same when pushing a roll through the mandrel; in fig. 6 - the same, after the end of pushing.

The device contains a roller table 1 for feeding the roll 2, fixedly mounted on the roller table 1, the mandrel 3 and located under the roller table 1 chain conveyor 4. The axes 5 of the rollers 6 of the roller table 1 are inclined to the horizontal plane at an angle a 20-70 ° Rollers b are installed in pairs on opposite sides roller table 1. On the frame of the roller table 1, a device 7 is mounted for movement along its longitudinal axis to seal the end of the packaging material 8. Pushers 9 are fixed to the chain conveyor 4.

The mandrel 3 is cylindrical. In the wall of the mandrel there are notches 10 and 11. The notch 11 of the mandrel 3 is intended for the passage of the pushers 9 of the conveyor 4. The end 12 of the mandrel 3 has a curved shape.

The device is equipped with a device for supplying unwrapping of the packaging material 8. The device is a carriage 13 on which the pivoting frame 14 and the basket 15 are mounted. The pivoting frame 14 is provided with a roller 16. The mandrel 3 can be equipped with at least one spring-loaded clamp 17. One end of the presser 17 is attached to the outer surface of the mandrel 3 with the possibility of rotation around the axis 18, and the other is provided with a roller 10.

The device works as follows.

From the pivoting basket 15 of the trolley 13, the pre-laid packing material 8 in the form of a sleeve is pulled through the roller 16 of the pivoting frame 14 in the direction of the mandrel 3. The edge of the packaging material 8 is pulled through the end of the end face 12 of the mandrel 3 and is fixed on its outer surface by the press roller 19. A piece of packaging material 8 of the desired length is separated from the sleeve, for example with a knife. In the device 7 close up the end of the packaging material 8, for example, using twine (Fig. 3). Then hands through the notches 10 gain packing material 8

on the mandrel 3, fixing it with a clamp 17 on its surface.

One of the pushers 9 of the conveyor 4 is installed in the extreme distant position from the mandrel 3. On the roller table 1 serves roll 2 (Fig. 4). Due to the inclination of the axles 5 of the rollers 6, the roll 2 is set strictly along the longitudinal axis of the cylindrical along the mandrel 3.

The chain conveyor 4 is set in motion. Under the action of the pusher 9, the roll 2 is pushed through the mandrel 3 (Fig. 5). In this case, the packaging material 8 begins to shrink from the mandrel 3., and, stretching between the front end of the roll 2 and the roller 19 of the pressing 17, tightly wraps the packed roll 2. The roller 19 also prevents the formation of a fold when wrapping the roll 2 The pusher 9 passes through the cutout 11 of the mandrel 3.

After pushing the roll 2 through the mandrel 3, the second end of the packaging material 8 is sealed and, if necessary, sealed. In this case, one sealed end of the packaging material 8 is inside the package. In the case of a crosslinked tubular packaging material, there are also connecting seams inside the package.

The packaging roll 2 is removed from the roll table for onward transportation.

Installing the clamp 17 on the axis 18 allows the mandrel to pick up a different amount of packaging material 8 (for packing rolls of various lengths).

The invention provides high-quality packaging of rolled materials by tightly wrapping the packaging material 8, improves the presentation of the packaging and facilitates sealing of the packaging (only one end of the packaging material 8 is sealed).
