Description

Devices for cleaning weaving spools from yarn residues are known, including an actuator, a spool-feeding device — pincers with rubber jaws covering the spool. The spools are orientated in the required direction, for example, head forward, on a conveyor belt, carried out with corresponding fixed stops, plates, etc., by means which are located along the conveyor belt. Also known are mechanisms for sorting shpules, for example, along their length, including an inclined tray for gravitational movement of bobbins, having a calibrating hole at the bottom for passing bobbins.

The proposed device for the automatic cleaning of weaving spools from yarn residues in comparison with the known devices of the same purpose makes it possible to increase the productivity of labor. The design feature of the device is that it is equipped with a mechanism for sorting a shpul having an inclined tray with two openings, one of which is profiled by a bare spool and serves to pass the spools without yarn residues, and the other, calibrating, the lower located opening is intended for skip spools with yarn residues to be cleaned. The tray is equipped with levers controlled by a common rotating cam and installed above the tray openings temporarily detaining the movement of the pulling along the tray, and two swiveling curved dogs, each of which lifts the spool head onto the tray when the corresponding lever interacts with the dog for further movement of the spool. A hopper and a conveyor for feeding spools to the pliers, cleaned of yarn residues, are installed under the calibrating hole of the bottom tray.

No. 141444-2N on FIG. I schematically depicts a device for automatic cleaning of weaving spools from yarn residues; in fig. 2 is a diagram of an inclined chute with levers and dogs in two projections; in fig. 3 is a diagram of an inclined tray in cross section showing two working positions of the dog and a lever interacting with it.

The weaving spools are loaded into the hopper 1, from which transport devices 2 of known construction are fed into the inclined tray 3 of the mechanism for sorting the spools. The inclined tray 3 is set at an angle of 45-50 ° to the horizontal; the bottom of the tray is made with two holes 4 and 5; Hole 4 is shaped along a bare bobbin and serves to pass bobbins without any yarn through it, and a hole 5 located downstream of the bobbin in Tray 2 is calibrated and serves to pass bobbins with normal yarn through it. Above hole 4, lever 7 is pivotal on axis 6, and lever 9 pivotal on axis 8 is mounted above axis 6. On the walls of tray 3, side fingers W are fixed, on which are mounted pivoting curved paws 1J, which interact with each lever corresponding to it (7 or 9 ). The movement of the levers 7 and 5 is controlled by a rotating cam 12 common to them, mounted on the shaft 13, driven in rotation from the transporting device 2 through a chain transmission 14. Under the aperture 4 of the tray 3 there is a bunker 15, into which the rods do not have Zhi And passed through the hole 4.

Under the hole 5 there is a bunker 16, into which the dies come with the usual yarn residue, passing through the hole 5.

In the event that a shank with a normal yarn residue passes over the hole 4, then this spool does not pass through the hole 4; the cam presses the end of the lever 7, the other end of this lever rises and frees the way for further movement of this spool along the tray 3; when the lever 7 is rotated, the latter acts on the protrusion 17 of the pawl 11, which rotates on the finger 10 and with its lower curved end lifts the spool head on the tray, causing the spool with the usual yarn residue to move freely further along the tray holes 5, falls through it into the hopper 16. If the shred is on the remaining yarn more than usual, such a spool does not pass through the hole 5 and is temporarily retained on the tray; after actuation of the lever 9 and the corresponding dog, the spools with a large remainder of yarn from tray 3 are dropped freely into the hopper 18, and then returned to production for revision.

From the bunker 6, the spools with the usual yarn residue, sorted already from bare spools and with the high yarn shpules, are conveyed by the transporting device 19 to a cleaning machine to remove them from the yarn residues. In this machine, the pinhead first enters the tray 20, and after the cam 21 is actuated, the lever 22 moves freely into the box 23 and is installed on the closed tongs 24. At this point, the pusher 25 moves to the right and pushes it earlier sandwiched with rubber sponge ticks 24 spool.

When the pusher 25 retracts, the tongs 24 open, the spool enters the tongs jaws, which then, under the influence of the load 26, close and clamp the bobbin with the remnants of yarn. During the subsequent movement of the pusher from left to right, the shpul is pushed out of the jaws of the tongs 24, and removed from the spool and remaining in the tongs, the yarn is carried by the air flow of the suction fan to the receiving hopper for yarn residues.

The industrial usefulness of this proposal is confirmed by the Central Research Institute of the Cotton Industry, according to which the performance of the proposed machine is quite high (13-14 thousand spools per hour).
