Abstract

A device for stuffing a material into a tape of heat-adhesive film containing a means for forming a sleeve from a film, a pipe for introducing material into the sleeve, a device for forming a longitudinal seam and a mechanism for pulling the sleeve, characterized in that it is equipped with roll holders for the tape and combined tapes and guide bodies in the form of two pairs of rods with slit gaps between them, located at the ends of the pipe and designed to fix the position of the tape and combined tapes.

Description

The invention relates to packaging equipment and can be used in pulp and paper mills and in the food industry.

A device for manufacturing, filling and sealing bags is known, in which a two-layer tape of heat-adhesive material is pulled intermittently for the length of the bag from the roll, while the edges of the tape are welded together on one side, then a V-shaped cavity is inserted into which they are inserted laterally when the tape stops packaged pieces, bring the edges of the tape together and weld them together to form a V-shaped cavity, at the same time seal the bag with a transverse weld and cut it off atyvanii (author's Certificate. USSR №309877, publ. 07.26.71).

This device is complex in design, because when used for packaging napkins, you need a special robot to insert a stack of napkins into the V-shaped cavity. The device is not productive enough due to the discontinuity of the process and, in addition, does not allow the packaging of tissue material to obtain wound into a roll of tape.

Closest to the claimed is a device for packing material into a tape of heat-adhesive film, containing means for forming a sleeve from the film, a pipe for introducing material into the sleeve, a device for forming a longitudinal seam and a mechanism for pulling the sleeve (Lunin O.G., Dragilev A.I. ., Chernoivannik A.Ya.

Technological equipment of the confectionery industry. Moscow, ed. Light and Food Industry, 1984, p. 339, Fig. 1X.8).

This device is intended for packing loose products - crackers, nuts - into bags of film tape with the simultaneous manufacture of the latter. However, it does not have design features for packing tapes, for example, from tissue paper to film tape to produce a combined tape-semi-finished product of cut tissue packages.

The technical result of the claimed device is to solve the problem of packing material in the form of a tape into a shell of heat-adhesive film to obtain the product in the form of a combined tape in a roll.

To solve this problem, a device for packing material into a tape made of thermally adhesive film containing a means for forming a sleeve from a film, a pipe for introducing material into a sleeve, a device for forming a longitudinal seam and a mechanism for pulling a sleeve, according to a utility model, is equipped with roll holders for being packaged and combined tapes and guiding bodies in the form of two pairs of rods with gaps between the rods located at the ends of the pipe and designed to fix the position of the plug washable and combination tapes.

The figure shows a diagram of the proposed device.

A device for packing material into a tape from a heat-adhesive film contains a roll holder 1 for a tape of tissue paper, a roll holder 2 for a tape of a heat-adhesive film and a roll holder 3 for winding a combination tape associated with a drive for rotating it (not shown). Between the roll holders 1 and 3, a forming pipe 4 and a means 5 covering it are formed to form a sleeve from the film. The device has guiding organs in the form of two pairs of rods 6 and 7 located at the ends of the pipe. The rods in each pair have gap spaces and

are designed to fix the position of the tape and combined tapes relative to the pipe 4. Between the means 5 for forming the sleeve and the pipe end facing the roll holder 3, a device 8 for forming a longitudinal seam, made in the form of an electric heater, is installed. The device has a mechanism for pulling the sleeve, made in the form of rubber rollers 9 associated with the drive of their rotation (not shown).

The device operates as follows.

The tape of heat-adhesive film from the roll holder 2, tucked between the tool 5 for forming the sleeve and the forming pipe 4, is pulled down by the mechanism 9, which presses the film tape to the pipe (according to the drawing) and is folded into the tube, while the edges of the tape overlap each other and welded together. The tube-like shell is flattened by the guide rods 7, passing between them, and wound onto the roll of the roll holder 3. At the same time, the tape of the material to be packed from the roll holder 1 is rewound onto the roll of the roll holder 3, passing through the slotted spaces of the guide bodies 6 and 7. As a result, the combined tape is wound on the roll holder from two layers of a film and a tape of material, for example, tissue paper, between them, segments of which can be attached externally or internally to film bags and cardboard boxes with food product.
