Description

The invention relates to elements of hoisting-and-transport and robotic systems intended for the capture and subsequent transfer of flat soft parts, and may find application in the garment industry.

The aim of the invention is to expand the technological capabilities of the device.

FIG. 1 shows the device, a general view; in fig. 2 - drive rotation of the needles, cross section; in fig. - characteristic operating positions of the device and its structural elements.

The device includes (Fig.1,2) supporting hollow cylinder 1 with a protrusion 2 and a hanging hole 3. Support

cylinder 1 is divided into two parts A and 5. In the inner cavity of the working part C on the shaft 6 on the bearing axis 7 by means of holders 8 and 9 are fixed bent needles 10 and 11. In the upper part 5 of the supporting cylinder 1 there is placed a drive for turning the needles, pneumatic cylinder 12 with a rotary cavity 13. On both sides of the fixed sector 1 compressed air is supplied through channels 15 and 1b. Above the pneumatic cylinder 12 there are mounted regulating supports 17 and 18 with microswitches, which, together with the protrusion 19 of the cavity 13, limit the angle of rotation of the shaft 6 with the needles 10, 11. The needles 10 and 11 are curved concentric and equidistantly located relative to the working clamp

The contour of the supporting cylinder 1 is fixed on the bearing axis 7 so that it can be rotated on it and displaced along and across it.

The device works as follows, (3, 4).

At start-up, the device is lowered (FIG. 3) and the lower part k of the reference

bakes their equilibrium displacement and rotation inside the support contour, where the gripping part is arched from the pressure of the support contour and raised upwards. At the same time, the needles are mounted on a horizontal bearing axis, which provides the transmission of needle movement and provides orientation

grip and wide adjustment of the angle of rotation of the working needles (by interchanging the regulating elements), since a change in the angle of rotation ensures the capture of parts of different thickness o

The proposed capture can be used in the clothing industry.

Claims (2)

1. A device for grabbing textiles, containing a table for placing the product, a supporting hollow cylinder placed above the table with The reset of the part 20 is carried out by pu- the compressed air supply to the opposite (left) cavity of the pneumatic cylinder 12 through the channel 16, as a result of which the cavity 13 and the shaft 6 rotate counterclockwise and the needles 10, 11 exit the part 20. The angle of rotation in this case is limited by the adjustable support 17- reset part 20 must be pressed to the bottom of the support cylinder 1 to some table (the time of reset is not shown). Depending on the type and thickness of the gripping part 20, the positions of the needles are adjusted in the vertical and horizontal planes by displacing the holders 8, 9 along and across the bearing axis 7o. The angular position of the needles 10, 11 is adjusted by rotating the holders 8, 9 on the axis 7. The effect of the use of the invention is to increase the technological capabilities of the grip and is achieved due to the fact that the needles are bent concentrically clamping 35 40 45 50 the contour of the support cylinder, which is secured to the table. a working base with a table, a gripping element on the cylinder that has a curved needle mounted in the holder and a predetermined rotation drive of the holder, characterized in that, in order to expand technological capabilities, the gripping element additionally has at least one bent hole, and the shaft rotation drive.
