Description

one

A device for unloading hosiery products in an oriented position from a pvtemsystem, such as a stocking machine, comprises an orienting chamber with inlet and outlet nozzles and a rotating bottom associated with a machine control mechanism, a device for gripping the end of products located in a chamber opposite the inlet nozzle and having a perforated safety shut-off valve mounted and secured in front of the outlet.

The purpose of the invention is to increase the reliability of the device.

This is achieved by attaching a plate to the retaining flap along the longitudinal axis of the chamber, separating the air flow.

The plate separating the air flow can carry a friction liner from the inlet side.

Pa figs. 1 shows the orienting camera, general view; in fig. 2 - a device for gripping the end of a hosiery, general view; in fig. 3 - technological scheme of the device; in fig. 4 shows a variant of the device with an installation for joining stocking toe; in fig. 5 is a flow chart of the operation of the plant, but FIG. four; in fig. 6 shows the mechanism for controlling the return bottom of the device in case it is used with the installation for syschivanie toe hosiery products according to phi / g. four; in fig. 7 is a diagram of the operation of the mechanism for controlling the turning bottom; in fig. 8 shows a version of the device with a stocking machine having a mechanism for pneumatic release of a hosiery product.

The proposed device contains an orienting chamber / with an inlet 2 and an outlet 3 with nozzles and a rotary bottom 4. The rotary bottom 4 is connected to an orienting chamber / two brackets 5, a net 6 and an axis 7. A device for gripping the end of the hosiery is provided with a separating

an air note with the plate 8 and the holding flap 9. The plate 8 has a protruding liner 10 made of friction material and inserted into the front part of the plate 8. Parallel to the outlet of the chamber 1, a safety flap // is installed, preventing the product from flying into the general pneumatic system in case of tearing the stocking off the fixture for grabbing koitsa products. At the beginning of the orienting chamber / mounted, the ejector 12 of the hosiery product is rigidly mounted on the rotary bottom 4 and made in the form of a figured rod. The gate 13, which overlaps the air note in the orienting chamber /, can be installed inside the outlet nozzle 3 nl in

control valve 14 of the rotary bottom control mechanism 4.

The installation for sewing the toe of a hosiery consists of an orienting chamber 1 with a swivel control mechanism, a device 15 for double turning the hosiery made in the form of a bent tube 16, a container 17 for collecting unfolded hosiery, a work table 18 and a sewing machine 19. The pipe 16 is installed on the desktop 18 with the possibility of rotation.

The rotary bottom control mechanism includes a pneumatic cylinder 20, a piston 21 connected by a connecting rod 22 and a lever 23 with an axis 7, a control valve 14 in which the axis 24 of the gate 13 is connected to the pipe 16 via a lever 25, t 26, a plate 27 attached to the flange 28. The flange 28 is provided with a rubber sealing ring 29 preventing air loss at the junction of the pipe 16 with the orienting chamber 1. The rotary bottom 4 is returned to its original position by the spring 30. The distribution valve 14 is connected to the suction side of the fan 31 by the pipe 32.

In the case of using the proposed device with a stocking machine, the control mechanism of the rotary bottom 4 and the gate 13 includes a control drum 33 with a plate 34, transmitting the movement of the gate 13 and the turn bottom through levers 35, flexible cables 36, bars 37 and 38. In the initial position the bottom of the rotary 4 and the gate 13 are returned by the springs 30 and 39. The orienting chamber / is connected to the stocking pipe 40 of the stocking machine by the inlet 2.

The hosiery is oriented in the proposed device as follows (Fig. 3).

A stocking 41, converging, for example, from a stocking machine, flies at high speed through an inlet 2, depending on the type of masking with a toe or side forward, overcomes, due to inertia forces, the folding force of the airflow of the orienting chamber / and enters the shutter 9 of the gripping device and fills the space between the plate 8 and the wall of the chamber / (FIG. 36). The rest of the stocking unfolds under the action of air flow and stretches along chamber 1 (Fig. 30).

The head (side) of the stocking 41 is held by sucking the retaining flap 9 and engaging with the friction liner 10. Since the distance between the two flaps 9 and 11 is approximately equal to the length of the stocking, it is full-length and orientated. After that, the gate 13 interrupts the air flow, thereby terminating the air flow, and the straightened stocking when turning the bottom 4 falls into the container 17, while the ejector 12 contributes to a lighter and

uniform loss of stocking from the chamber / (Fig. 3g).

The unit for stitching the toe of a hosiery, equipped with a device for high-.

loads of hosiery products from the pneumatic system with orientation on the position, works as follows (phi 5g and 7).

The tube 16 is connected to the inlet of the alignment chamber: / and held in

this position due to the rubbing of the rubber ring 29 against the wall of the orienting chamber 1. The previous stocking 4.1 is in the chamber / in the stretched oriental position and is held behind the toe by the device

to grip the end of the product, thanks to the air flow passing through the pipe 16 and the chamber (FIG. 5 a).

A new stocking 41 lets the toe forward into the pipe 16, holding it overboard (Fig. 5e).

The pipe 16 is rotated around the axis of rotation and the new stocking 41 is turned over, pulling it onto the pipe 16. The movement from the rotation of the pipe 16 is transmitted through the plate 27, that is, the rod 26 and the lever 25 of the axis 24 of the gate 13.

The gate .13 rotates into the second extreme position (Fig. 76), and the air begins to be sucked out of the pneumatic cylinder 20. Due to the created vacuum in the pneumatic cylinder, the pistol 21 is lowered to the lower position

thus turning the bottom 4 and opening the exit from the chamber 1 preddup), he stocking 41. Stocking falls out of the camera / into the container 17 (Fig. 5 g). The head of the next stocking is secured in the sewing machine 19 (Fig. 5 (3). The pipe 16 is returned to its original position, connected to the inlet of the chamber 1. Movement from the rotation of the pipe is transmitted to the gate 13, which turns to the first extreme position, returning the suctioning air flow from the pneumatic cylinder 20 again into the chamber / (Fig. 7a). At that, the rotary bottom 4 is returned to its original position by the spring 30. The next stocking is sucked into the chamber through the pipe 16, where it is oriented in the manner described. When the stocking is sucked into the pipe 16, it turns out evident from the inside, and a seam on the toe of the stocking inside the interior of the article.

The basic operation of the device with the automatic stocking does not change as compared to the above. The program of the sequence of actions of the working bodies (the turning bottom 4 and the slide 13) is set by the drum 33 of the control of the stocking machine.
