The main patent relates to a device for removing and turning stockings and socks or other tubular knitted parts on single-cylinder or double-cylinder circular knitting machines with a gripping tool designed as a clamp to grasp and hold the beginning of the goods and for releasing the same after completing the knitted part, in which the clamp in a stationary Tube is arranged movably.

The invention is based on the object of further developing the device according to the main patent train that the gripping tool designed as a clamp is designed simply and reliably.

Gripping tools for gripping and holding the beginning of the goods are known per se. With these Gripping tools, however, could not both pull off and turn the goods.

According to the invention, this object is achieved in that the clip by a rope with a trigger weight connected is. This embodiment of the invention provides a particularly simple control of the gripping tool, which is characterized by complete operational reliability.

The trigger weight is expediently piston-like in a cylinder, which has a connecting piece at the lower end has for the supply of compressed air, stored.

The clip itself is advantageously formed from two cones that can be moved relative to one another.

In order to avoid the rope and thus the trigger weight being taken along by the rotating goods is, the rope is on the part of the clamp that carries the outer cone, via a ball bearing attached.

The part of the clamp which carries the inner cone has an annular shoulder on the outside, which rests against a corresponding shoulder in the guide tube at the lowest position of the clamp, whereby a release of the knitted part is effected.

For the subjects of the subclaims, protection is only given in connection with the main claim desired.

An exemplary embodiment of the invention is shown schematically in the drawing. Other features and advantages of the invention are explained with reference to the drawing. It show the

Fig. 1 to 3 three different working positions of the gripping tool,

F i g. 4 shows a detail of FIG. 1 in an enlarged view.

The F i g. 1 and 4 show the gripping tool, designed as a clamp, consisting of part 1 with outer cone and part 2 with inner cone.

Both cones can be moved towards each other. Part 2 with the inner cone is in a hole a rod 3 is guided, which has a ball bearing 4 at the upper end. There is a Fastened rope 5, which is guided over the rollers 6 and carries a trigger weight 7 at the free end. The trigger weight 7 is mounted in a cylinder 8 like a piston. At the bottom of the cylinder 8 is a nozzle 9 is attached for the supply of compressed air. In the lower needle cylinder 10 of the circular knitting machine there is a ring 11, which is equipped with compressed air nozzles pointing downwards at an angle is.

The operation of the device according to the invention is as follows: The clip is after F i g. 1 in the lowest position. It lies with the annular shoulder 13 on a corresponding one Counter-paragraph 16 in the guide tube 14. The rope 5 is relieved. As a result, the Cone 1 downwards so that the clamp is open. The stop 15 below the ball bearing 4 is determined the opening of the clamp. In this position the circular knitting machine starts a new piece of fabric to knit. As much fabric is knitted until the first rows of the fabric are in the area of cones 1 and 2 arrive. Then the clamp is closed by pulling on the rope 5 and thus captures the goods. The tension of the rope is caused by the dead weight of the trigger weight 7.

works. The relief of the rope arises from the fact that compressed air is blown into the cylinder 8 via the nozzle 9. As the knitting continues, the trigger weight 7 moves downwards and pulls the clip with the piece of goods clamped onto it upwards. Here, the item of goods is inevitably turned. This position is shown in FIG. 2 reproduced. After the item has been blown off, compressed air is again introduced through the nozzle 9, the trigger weight 7 is guided upwards, the clip falls back into its starting position (Fig. 1) and presses the item inevitably downwards and releases it in the lowest position. Here, the item of goods enters the nozzle ring 11 with the nozzles 12. A short blast of compressed air is given into this ring line and the stocking is blown out downwards. The various switching operations are carried out in a known manner by means of the switching drum of the circular knitting machine in a mechanical, pneumatic or electrical manner. Patent claims: 1. Device for removing and turning stockings, socks or other tubular items Knitted parts on single-cylinder or double-cylinder circular knitting machines with an as Clamp trained gripping tool for detecting and holding the beginning of the goods and for Releasing the same after completing the knitted part, in which the clamp in a stationary Tube is movably arranged, according to patent 1228022, characterized in that the clamp (1,2) is secured by a rope (5) is connected to a trigger weight (7). 2. Apparatus according to claim 1, characterized in that the trigger thread (7) like a piston is mounted in a cylinder (8), which at the lower end has a connector (9) for supply of compressed air. 3. Device according to claims 1 and 2, characterized in that the clip from consists of two cones that can be moved against each other (1.2). 4. Apparatus according to claim 3, characterized in that the rope (5) on the part (2). the clamp, which carries the inner cone, is attached via a ball bearing (4). 5. Device according to claims 1 to 4, characterized in that the part of the clamp (2), which carries the inner cone, has an annular shoulder (13) on the outside, which against a corresponding paragraph (16) in the guide. '. tube (14) rests on the lowest position of the clamp. Considered publications:
