Description

The unit includes a carriage / for laying cloths, having devices for unwinding roll 2 and trimming scaffolds, koitsevy clamping rulers 3 and 4. When laying, trolley 1 performs back-and-forth movements of the conveyor belt 5. Cutting device, Carrying the working tool, includes carriage 6, moving along stationary guides along the flooring, and carriage 7 moving across the flooring with the guide carriage 6. The carriage 6 has four guide drums 8 for the belt conveyor 5. The carriage 7. a vibrator 9 for communicating the blade 10 with vibratory motion. The rotation of the knife around the axis occurs from the actuating motor M of the software device, which is also mounted on the carriage 7, and the gear pair i / 2.

The mechanical positional drive of the carriage 6 consists of the power motor 13 and the fur and the amplifier 14. The control link | У5 of the amplifier is kinematically connected with the screw 16, having for this purpose a circular groove. A screw is mounted on a key shaft 17 with the possibility of movement along its axis. Shaft 17 is mounted in the supports of the amplifier housing and is kinematically connected with the control motor 18 mounted on the amplifier housing. The screw to 16 is in engagement with the fixed toothed rack 19. The carriage 7 has the same drive.

The device for clamping the flooring consists of a skeleton 20 with a tension drum 2L, a drive drum 22 and adjoining strips 23 and 24. There is a belt 25 on the drums and straps of the tensioning belt 25. On the shaft of the drive drum there is a gear 26 that engages with a non-moving toothed rack 27. The frame 20 is installed in the guide carriages 6 and moves with it along the flooring and is installed at a height of the flooring by displacing the guideways (in height). Springs (not shown) are provided in the guides for adjusting the pressing force. i

The unit works as follows.

After the production of the flooring, the belt conveyor 5 is turned on at the flooring position and the flooring is moved to the cutting devices. During this period, the carriages 7 are extended or the knives are lowered “below the upper plane of the belt conveyor, and the clamps are raised. The required distance between the knives and the cutting device displacement knobs are set one before the other. After installing and securing the flooring above the cutting devices, the clamps are lowered.

Next is the simultaneous cutting of the flooring along the entire length. When moving the carriages 6 and the clamps along the deck, the relative speed between the conveyor belts and the clamp of the deck is equal to zero.

Simultaneously with the opening of the first astil, the manufacture of the second B of the laying position is carried out.

After the flooring has been cut, the belt conveyor is turned on again and the cut flooring is moved to the picning position (not shown) and at the same time the new flooring passes from the first to the second position. The process is repeated.

When cutting the mechanical positional drive carriages works as follows.

As a result of the rotation of the shaft 17 from the control motor 18, the screw to 16 moves in the axial direction along the rail 19. In this case, the control link 15 of the amplifier is rotated through a certain angle. As a result, the amplifier body moves along with the carriage. The amplifier is powered by the power motor 13.

Claims (1)

Invention Formula The machine for cutting the fabric webs is primarily in the garment industry, containing a belt conveyor, a carriage for laying material webs installed on the guides, means for pressing the webs in the cutting area and a device for cutting material webs connected to a software control unit and having a vertical a knife and a drive, characterized in that, in order to increase reliability, the blade cutting device is located under the belt conveyor and consists of two carriages, mounted on the guides arranged in mutually perpendicular planes, one of the carriages mounted iC capable of moving along the floor of the canvases, and has tension drums for a belt conveyor, two drums installed at the level of the working branch of the belt conveyor with a gap, while the vertical knife located in the gap between these drums and mounted on another carriage, and the means for clamping the cloths consists of the drive drum mounted in the housing and the clamping straps located under the ribbon This conveyor is symmetrical with respect to the vertical knife, the casing being mounted on guides of the carriage mounted for movement along the floor of the canvases. 5 The source of information accepted - attention during examination: Phage. /. 835917-6 bo1.
