SU1331778A1 - Arrangement for laying out web of preset length - Google Patents

Abstract

The invention relates to the leather industry, the footwear and apparel industries. The purpose of the invention is to improve the reliability and accuracy of the laying by placing the carriage on the rods with the ability to mix, knit and bond the knife body and drive it kinematically with one flexible connection. The carriage contains two parallel shafts on which clamps are mounted by means of equal levers. The body of the knife mechanism is housed in a guide. A disk knife rigidly connected with an asterisk, a presser knife and tension stars are installed in the housing. The housing and the sprocket are kinematically connected to the drive chain. 4 il. oo oo | 00

Description

The invention relates to leather haberdashery, shoe and apparel industries of light industry.

The purpose of the invention is to increase the reliability of work.

FIG. 1 shows a device, a general view; in fig. 2 - carriage, top view; in fig. 3 - the mechanism for clamping the material in the closed position; in fig. 4 - knife drive mechanism.

In this case, the rubberized shaft 24 of the unwinding mechanism 11 of the web using a friction clutch (not shown) does not have a web from a roll at a speed equal to the speed of the carriage 5. The roll holder 8 is mixed across the direction of movement of the web to the pneumatic cylinders 9 so that the edge of the web is in a certain place

After stopping the carriage 5 is turned on

A device for laying the web for the mechanism 10 pieces of web by

chains 23. At the same time, the sleeve 18 moves to the extreme right position and the same chain 23 interacting with the asterisk 20 causes the disk blade 19 to rotate. A measured piece of blade is cut off. Then, the grippers 14 of the carriage 5 are opened and the front end of the cut piece of web falls on the table. The carriage 5 returns to its original position. In this case, the unwinding mechanism 11 of the Cluster 5 contains two parallel 20 lots and the pneumatic cylinder 9 is braked.

Open grippers 14 do not shift the web layer.

After the production of a given thickness of flooring, equal-sized rocker arms 2 are actuated, the rods 3 are raised together with the carriage 5 and the rods 4. In this case, the tension of the chain 6 does not change because it bends around the sprockets 27 installed rotatably at the ends of the yoke length contains 3 rods mounted on the frame 1 by means of equal-sized rocker arms 2, on which rods 4 are placed, carriage 5 which is placed on rods 3 and kinematically connected by a chain b with the drive shaft 7, the roll holder 8 with the pneumatic cylinder 9 equalizing chrome ki cloth mechanisms 10 pieces and unwinding 11 cloths.

shaft 12, on which, by means of equal-sized shatunov 13, grippers 14 are mounted. On one of the shafts a gear wheel (not shown) is fixed, kinematically connected to the pneumatic cylinder 15 by means of a toothed rack 16.

The mechanism 10 pieces of fabric consists of a cutting line 17, which houses the holder 18 of the knife mechanism. In the cage 18, a drive disk knife 19, rigidly connected with an asterisk 20, a presser knife 21 and tensioning stars 22 are mounted. The holder 18 and an asterisk 20 are kinematically connected by a chain 23 to the drive.

The web unwinding mechanism 11 comprises a rubberized shaft 24, kinematically connected with the drive shaft 7, the pressing shaft 25 and the bending shaft 26.

A device for laying a web of a predetermined length works as follows.

thirty

villages 2. The flooring sags between the rods 4. The carriage 5 is moved by chain 6 to the extreme right, picking up the flooring in the book and dropping this book at the end of the device. After that, the carriage returns to its original position.

Claims (2)

Invention Formula A device for laying a web of a predetermined length, containing a roll holder, a carriage with grips of a web, installed with the possibility of reciprocating. A web roll is installed in a roll / roll horizontal movement, a holder 8 and an edge of the material for filling the web, including cutting under shaft 26 bend and clamping ruler and drive disc knife, and shaft 25. The rods 3 are lowered, the carriage 5 movable in the vertical direction is in the extreme left position of the rod with the open grippers 14 transversely to them, the holder 18 with rod rods, characterized in that it is in the extreme left position. 45 in order to increase the reliability of work, The carriage is mounted on movable shtanga and has two parallel shafts with wedge parallelograms, on the slopes of which there are grips of the web, and the cutting mechanism has a guide and a knife holder located in it, which is connected with its drive by means of flexible coupling. The rods 4 are laid on the rods 3 through certain distances. When the device is turned on, the grippers 14 of the carriage 5 are closed by means of a pneumatic cylinder 15 and a toothed rack 16. Then, the drive shaft 7 is turned on, which through the chain 6 moves the carriage 5 to the pre-set distance 50 In this case, the rubberized shaft 24 of the unwinding mechanism 11 of the web using a friction clutch (not shown) does not have a web from a roll at a speed equal to the speed of the carriage 5. The roll holder 8 is mixed across the direction of movement of the web to the pneumatic cylinders 9 so that the web edge is in a certain place . After stopping the carriage 5 is turned on the mechanism 10 pieces of cloth by thirty 35 sat down 2. The flooring sags between the rods 4. The carriage 5 is moved by chain 6 to the extreme right, picking up the flooring in the book and dropping this book at the end of the device. After that, the carriage returns to its original position. Invention Formula IE × 15 5 27 2 27 1 Compiled by T. Gavrilov Editor P. GereshiTehred I. VeresKorrektor M.
