Abstract

The invention relates to the apparel industry, in particular to preparatory-cutting production. The aim of the invention is to improve the performance of the device. A device for multi-layer continuous laying of sheets comprises a carriage mounted on guides and pressure plates with locking needles on each of them. The device is equipped with a looper installed with the ability to provide cyclic automatic filling of the web loop into one of the two pressure plates during reciprocating movement of the carriage. On one clamping plate, the needles are horizontally arranged, and on the other, vertically. Actuators are available for reciprocating the slats and end switches of the carriage drives and end clamping slats. 1 hp ff, 5 ill.

Description

The invention relates to the preparatory-cutting production of the clothing industry.

The purpose of the invention is to increase plant productivity.

FIG. Figure 1 shows schematically a device for laying a canvas on a cutting table in the initial stage of the laying cycle, at the time of loading with a cloth shaker-looper for the fabric under the needles of the first end pressure bar - the formation of the first loop of the fabric web; Fig. 2 shows the same, at the moment when the carriage is under the needles of the second end pressure bar - the formation of the second web of fabric; in FIG. 3, view A in FIG. 1; figure 4 - node I in figure 1; figure 5 - node II in figure 2.

The device for laying cloths on the cutting table comprises a carriage 1 mounted on the guides of the cutting table 2, an envelope roller 3, a beater 4, mounted on

stationary cheeks 5 can be rotated about the axis 6 when the cable 7 is engaged with the roller 8 of the carriage 1 and can be returned to its original position under the action of the plumbs 9. On the cutting table 2, on one side are located the presser bar 10 with horizontal needles 11 and the actuator 12 vertical reciprocating movement of the clamping plate 10, and on the other hand, the end of the clamping plate 13 with the web clamps in the form of additional vertically arranged needles 14 and the actuator 15 of the vertical variable Pull end clamping strap 13.

From the actuator 16, a carriage 1 is driven by a chain transmission to the shaft 17 from two sprockets 18 by means of two circuits 19. Switches 20-23 of actuators 12.15 and 16 are located on both sides of cutting table 2. Roll 24 is fed from feed unit 25.

The carriage 1 consists of a transverse horizontal beam 26 with a wedge-shaped wall.

with a groove strip with grooves 27, the pitch of which coincides with the pitch of the position of the needles 14 in the end clamping bar 13.

The device works as follows.

The end of the web of the consumable roll 24 is passed through the envelope roller 3 and is applied to the needles 11 of the presser bar 10, which at this moment is in its extreme upper position. Turn on the drive 16 of the installation and in the future it works in automatic mode until the full layout of the fabric on the cutting table 2 layers. In this case, the carriage 1, by means of two circuits 19 from the actuator 16, is driven from left to right (Fig. 1). As a result, the switch 21 of the actuator 12 and the presser bar 10 are first triggered vertically, clamping the end of the fabric, and the beam-type looper 4, as a result of releasing the cable 7 from the engagement with the roller 8, returns to the position shown in FIG. As a result of further advancement of the carriage 1, the unwinding of the roll 24 and the laying of the first layer of the web occur.

When the carriage 1 (for example, a remote rod) reaches the limit switch 22, the drive 15 turns on the vertical movement of the end of the pressure bar 13 upwards. As soon as the carriage 1 reaches the end switch 23, the actuator 16 switches to the reverse movement of the carriage 1, as a result of which the latter stops and starts the reverse translational movement from right to left.

In this case, the carriage 1 switches the end switch 22 to turn on the actuator 15 to move the end clamping bar 13 vertically, which needles 14 penetrate the cloth web loop located on the wedge-shaped nose of the bar with the grooves 27 of the horizontal carriage beam 26. cutout table 2 end clamping bar 13. Next, when approaching the carriage 1 and the clamping plate 10, remotely (for example, using a rod), the switch 21 turns on the actuator 12 in a vertical displacement s up gib 10. The carriage 1 roll 8 engages with a rope 7, and

rocking-looper 4, rotating in the direction of the clock, tensions and refills the second loop on the needles 11 of the clamping bar 10. At the same time, the carriage 1 presses the limit switch 20 and the drive 16 reverses the movement of the carriage 1.

During the reverse movement of the carriage 1, the switch 21 turns on the drive 12 to move vertically downwards and the cycle of the foot set of the fabric with the required number of layers repeats.
