SU1570982A1 - Arrangement for separating and gripping soft parts from a bundle - Google Patents

Abstract

The invention relates to light industry, in particular, to means for automating loading and unloading operations with soft parts, and allows securely gripping the soft part and resetting it. This is achieved by performing a collet grip in the form of a vertically located elastic split ring with a cutout in its lower part, driving the diluting of its clamping elements with a membrane, the stem of which passes through the vertical axis of symmetry and has a pair of rollers interacting with the inner annular surface of the collet grip. 4 il.

Description

The invention relates to automation equipment for loading and unloading operations in light industry.

The purpose of the invention is to increase the reliability of

FIG. 1 is schematically staged device; in fig. 2-4 — device in characteristic working positions,

The device (Fig. 1) is made in the form of a collet grip 1, which contains a ring 2 of elastic material, cut along the side surface, the cut line 3 of which is facing downwards. The holder 4 with extension 5 is fixed to the upper part of the ring 2 for attachment to the robot arm or manipulator (not shown). The holder 4 holds the actuator membrane chamber 6 for diluting the gripping elements, which is placed in the inner cavity of the ring 2, the stem 7 of the membrane 8 passes through the vertical axis of the ring 2 and at the lower end 9 has a crossbar 10, which is connected to two support rollers 12 by brought into contact with the inner surface of the ring 2,

The proposed device, by means of a robot or a manipulator, makes a reciprocating motion over a pack 13 consisting of textile parts, for example, a cut of clothes (Fig. 2-4). Each time the gripper 1 comes into contact with the pack 13, the top part is separated from it. 14, which is then transported in the desired direction. The channel through which compressed air is supplied to chamber 6 is indicated in FIG. 1 position 15,

The device works as follows

Collet grip 1 by means of a process 5 is connected to a robot or a manipulator, and from it receives a reciprocating motion above the pack 13. When lowering the grip 1 at the same time

Claims (1)

Claims of the Invention A device for separating and gripping soft parts from a pack, comprising a collet gripper mounted in a housing and placed between its elastic elements and a dilution drive, which is characterized in that (Line 3 cuts (sponges) ring 2 zak-15 improve reliability, collet these parts, provides the formation of a loop and tightening it into the cavity of the guide ring collet gripper | that, and also reliable conclusion of needles when dumping a detail, Claims of the Invention A device for separating and gripping soft parts from a pack, comprising a collet gripper mounted in a housing and placed between its elastic elements and a dilution drive, which is characterized in that  increased reliability, collet rushes and seizes the upper part 14 with its working areas (for its micro-asperity and deflection of the part into the loop). Then, the gripper 1 rises (FIG. 4) and carries the piece 14. in the desired direction. The use of the proposed device makes it possible to reliably grip the soft part with an end pointed part of the collet grip due to the forces acting uniformly along the surface. the grip is made in the form of a split ring mounted in a vertical plane, the cut line of which is made at its lowest point, the drive of the collet grip is made membrane, and its rod passes through the vertical axis of symmetry of the ring and has a pair of rollers fixed on it interaction with the corresponding internal the surface of the ring.  ////// Л.
