Description

Known machines for spreading and cutting fabrics consist of a reciprocating carriage, devices for clamping the ends of the fabric and knives for cross-cutting the fabric.

A distinctive feature of the proposed machine is that, in order to increase labor productivity, the machine is designed as mounted along the chain and moving along a closed path, laying the material on the table, carriages with clips to grip the material, devices for releasing the material from the carriage clamps when a given length of flooring is reached, a device for clamping and cutting material laid on the table, tools for controlling the carriage clamps and a device for clamping and cutting material.

FIG. 1 and 2 shows the machine, side view and top; in fig. 3 - carriage, top view; in fig. 4-device for controlling the Tipnzhim and knives carriage, top view; in fig. 5 and 6 — device for releasing the material from the carriage clips, top view and side view.

On the support 1 (fig. 1) two stars 5 are fortified, and pa. The support 2 is reinforced with two stepped pulleys 4- Between the sprockets 3 and the pulleys 4 there are tensioned chains of the Gall 5, forming a double-chain conveyor. A table 6 is mounted on top of the conveyor. On the conveyor chains there are two carriages 7, which are located at a distance of half the chain length from each other and are moving along a closed path. The carriages 7 are equipped with a device for laying fabric on the table 6 and cutting it, and consist of the following parts (Fig. 3): frame 5, two forks 9, two wheels 10, two levers 12, ticking 13 movable in the vertical plane through the lever 14 of the knife / 5 and the fixed knife 16. forming a knife with the knife / 5 when lifting it.

For feeding the fabric to the carriages at the front edge of the table there is a node 17 for guiding and feeding the fabric (Fig. 1).

The control of the levers for the tacks 13 of the fabric (Fig. 3) and the knives 15 is carried out by the platform 18 by means of fixed copiers 19

(fng. 4). The cutting of the cut end of the fabric is held by means of two spring-loaded lifting and turning shrihvats 20 mounted on the front part of the platter.

For stacking and holding the end of the table, the tissue released from the carriage clips has a spring-loaded plate 21 on the axis in the rear part of the table (Fig. 5).

Work on the machine is as follows.

The fabric is fed to the flooring masks in pieces, folded with a book or in rolls, and fastened on the grooves (fig-1) of the fabric direction and feed unit 17 (fig. 1), which is a l-shaped console. The fabric is then tensioned onto the guide rollers 23, the end edge of the fabric should hang 15-20 cm below the last roller. The rollers 23 are rigidly fixed to the posts, and their axes are not parallel to each other, which allows moving to one stand When the carriage 7 comes out ((zig-1) on the table 6 are copiers 19, act on the levers 14 (Fig. 3) —the movable pin 15 raises to the vertical position, and the levers 12 raise the Clamps hinged to them in the vertical position 13 (Fig. 3). The end of the fabric, descending from the console of the node 17 (Fig. 1), lies down and the frame 8 of the carriage 7.

Upon further movement of the carriage 7, the levers 14 cease to interact; with copiers 19, and under the action of their springs, the clamps 13 are first lowered, and the pocketed 15, firmly pressing the fabric and pressing it into the groove of the trailing edge of the frame 8. tissue. The cut end of the already laid fabric is pressed by the clips to the table as the next carriage approaches.

The end of the fabric, fixed by the clamp 13 on the frame 8 of the carriage 7, is transported with it to the desired length of flooring, which is adjustable by means of the platform 22 installed on the table 6 (Fig. 5).

When the carriage 7 approaches the platform 22, the cams // (Fig. 3) of the carriage 7 go under the copiers 25 (Fig. 6) of the frame 24, raise the frame and allow the carriage 7 to allow free passage. The fabric then appears under the rotatable spring-loaded Plate 21. When the output of the carriage 7 from under the copier 25, the frame 24 drops sharply to its original position, while acting on the levers 12 (FIG. 3) of the hooks 13 of the carriage 7, which release the fabric. At the same time, the fabric is pressed against the plate 21 to the table.

After the end of the fabric is freed from the stickings of the carriage, the latter moves further along the plane of the table and goes under the table, and then comes back to its original position.
