Description

The invention relates to the production of soft roll roofing and hydro-insulating materials, for example}) uboroid, glassine.

The final operation in the production of these materials is to roll the web and pack the rolls.

A device for coagulating tape material into a roll and packaging of the latter is known. The device contains take-up rolls, a turntable, a pair of filling rollers with an overrunning clutch, two turntable refueling tables, a winding device containing a drive and two spools mounted on the p & a wrapping paper feeding mechanism including a pair of scissors and an adhesive dispenser. In addition, the device contains photocells that ensure the coordinated operation of the device 1.

However, changing the direction of movement of the web (paper) from one spool to another, i.e., redirecting it, is a source of device interruptions, which hinders performance and reduces work stability.

In addition, the redirection mechanism itself is structurally complex.

The purpose of the invention is to increase productivity by controlling the speed of rotation of the spools during the coiling and packaging of the tape material.

This goal is achieved by the fact that in a device for folding and packing tape material containing a rotor with spools for tape material and mechanisms for feeding tape material and packaging paper, hollow coaxially arranged shafts, each of which is connected to the spools, are installed coaxially with the rotor axis. belt drive assistance.

FIG. I shows the scheme of the winding part of the device; in fig. 2 is a diagram of a three-line uniaxial transmission of rotation to the spools from a three-line gearbox.

The device comprises a rotor 1 in which three spools 2 are mounted, adjacent to which on the suspensions 3 are pivotally suspended .1 padding rollers 4 (in pairs). Each pair of rollers 4 is covered by at least two endless yarns 5. A canvas 6 is fed into a spool with rollers 7 along a table 8. Paper 9 is fed by rollers 10. A pneumatic cylinder II pushes 2

roll with spool. The rotor 1 rotates in the bearings of the frame 13 (Fig. 2).

Hollow shafts 14 and 15, as well as shaft 16 are mounted in the hollow axis of the rotor 1. At the ends of these shafts pulleys 17 are fitted, which through a belt (or other) gear 18 and pulleys 19 with (rotation from the gearbox 20 spools 2. The rotor is rotated through 120 ° by a drive 21. Each spool can receive a rotation according to the program specified in the gear shift box, regardless of whether it is on the way or at a stand.

The device works as follows.

At position I, the measuring piece of web is rolled up into a roll. Until the end of the spool rolling, the rotor is moved to the position P. The position 1 is occupied by the free spool. After

Filling the spool with a blade begins to roll on the second spool. At the same time, the first roll is being packed at the positions And. The rolling rollers 4, with their weight, press a piece of paper 9 (with pre-applied glue) to the surface of the roll. The wrapping of the roll wrapping paper.

Then, by the next turn of the rotor, the free spool occupies position 1. The spool with a roll, for

Q packaging, and the position of the HI comes spool with a packed roll. At the 1N position, the pneumatic cylinder 11 with paw 12 pushes the roll off the spool. Thus, one after another, operations for the formation of a packed roll and forcing it from the spool for

filing to the warehouse.

 The increase in productivity is achieved by the fact that the rotation of the rotor 1 is started before the end of the rolloning. Rolling as well as packaging continues in the process of turning the rotor, which reduces the duration of the cycle of packing and packaging by about. The increase in productivity (due to reduction of the cycle), copy quality and ease of maintenance is achieved due to the presence in the rotor case of the winding part of the uniaxial three-piece rotation transfer device from the box of speeds to the spools.

The capacity of the device, for example, in the production of roofing material reaches 150 m / min compared with 100-110 m / min in known devices.
