Description

to textile

The invention relates to industrial values.

A device for putting the spools on the spindle of the spinning machine, which contains a spool clip mounted on the holder, which is an elastic chamber connected to the compressed air supply system and the drive of the holder, is known.

However, during the operation of such a device, spools are damaged when exchanging the latter due to the lack of a sensitive safety device, which, if the process fails, stops or switches the further movement of the device clamp.

To ensure reliability in operation, the proposed device has a pair of contact elements electrically connected with the holder drive, one of which is located on the holder and the other on the spool clip, while the spool clip is mounted on the holder by means of an elastic element , one of the contact elements is made in the form of a disk, and the second - in the form of a sleeve, mounted coaxially to the clip of the spool.

FIG. 1 shows the proposed device, a cross-section with a diagram of the attached safety device} in FIG. 2 is another variant of the device; in FIG. 3 a part of the contact element according to FIG. 2, top view

The device comprises a holder 1 on which the clips 2 of the spools 3 are installed, located in one row, one after the other along the spinning machine (in Fig. 1 one clip is visible).

Each clamp 2 is an elastic chamber connected to a compressed air supply system, for which the holder 1 has a channel 4 extending along all the lengths of the holder and branched from it to the channels 5 connected to the clamps 2.

Claims (2)

When compressed air is supplied, the elastic chambers of the clamps after their insertion into the upper ends of the bobbins can be simultaneously expanded, while the clamp is pressed against the walls of the spool 3 from the inside of the latter and captures the spool. 3 In order to increase the reliability of the device, it has safety devices in case of a breakdown of the normal relationship between the clamp and the spool, which consists of a pair, which are connected with the drive of the holder of the contact elements 6 and 7. The contact element 6 is located on the holder 1, is filled In the form of a sleeve fixed to the holder 1 with the help of a snail 8. If the sleeve is attached to it, for example, with the help of glue, an elastic gasket 9 of elastic material that protrudes slightly from the bottom of the sleeve. For example, a second contact element 7, made in the form of a metal disc, is attached to the lower plane of the gasket 9, for example, with a nipple 10 with a circular metal holder 11, on which the clip 2 of spools 3 is mounted. the elements 6 and 7 are mounted coaxially with the clip 2. Due to the fact that the resilient gasket 9 protrudes from the contact element 6, a gap of about 1-3 mm is formed between the last and the second contact element. Thus, the contact elements 6 and 7 are electrically isolated from each other. In the longitudinal direction in the holder 1, a metal rod 13 is fastened through the insulation 12, to which the electric wire 14 is attached, the other end of which is connected to the contact element 7. The corresponding electric wires 14 are attached to the disks of the contact elements 7 at all the other clips in the row. Thus, the second contact elements 7 of all clips are connected to an electrical circuit 15, which receives power from a voltage source 16, with one source pole connected via a relay 17 and parallel to a signal lamp 18. In the event of a normal relationship between clamp 2 and spool 3, during operation when the holder 1 moves, when the latter encounters an obstacle arising as a result of this violation in the axial direction (along arrow A of Fig. 1) or lateral resistance (along arrow B or B of FIG. 1), the clamp 2 moves towards zhatelyu 1, compressing the elastic gasket 9. In this second pin, the first element 7 pervshg contacts the contact element 6 and the electric current through the relay 17 turns off the motor (4 to 850 cherte5 not shown) of the drive chuck and the movement of the device is stopped. In this case, the signal lamp 18 indicates the place of occurrence of the defect, which is eliminated. In the device (see, variant 2), the second contact disk 7 can be made in the form of a spring washer with beam segments 19 separated by slots 20 (see .. FIG. 3), and this washer is sandwiched between the jaw 21 nipple 22 and the disk 23 attached to it. An elastic gasket 9 is attached to the disk 23 with glue, an annular disk 24 is attached to the upper plane of the gasket 9, attached to the first contact element 6. Fixed in the bottom h As an apparatus, an elastic chamber — Clamp 2, as in the previous constructions, is connected with a compressed air supply system through channel 5 that leaves the main channel 4. A safety process can be carried out if the normal Relationship of clamp 2 and spool 3 fails during operation. by deforming the gasket 9 and subsequent closure, the spikes of the contact elements 6 and 7, and also if there is a clamp at the entrance, and 2 at the upper end of the spool 3, the latter bends one of the radial segments 19 and it comes into contact with the upper, contact, element 6. Formula Invention 1, the device for putting the spools on the spindle of the spinning machine, which has a clip mounted on the holder, spools, which is an elastic chamber connected to a compressed air supply system, and a holder drive that differs from the chain of increase of reliability of the device, it has electrically connected with the drive, the holder has a pair of contact elements, one of which is located on the holder, and the second - on the spool clip, while the clip, the spool is mounted on the holder by means of an elastic element. 2. The device according to claim 1, is distinguished in that the resilient element is a pad of elastic material. h Device on PP. 1-2, that is, with one of the contact elements made in the form of a disk, and the second in the sleeve, mounted coaxially with the bobbin clip.
