SU69730A1 - Device for switching drums winding shafts - Google Patents

Description

BACKGROUND OF THE INVENTION Apparatuses for wounding the bases of a shaft shoe made of a carding fleece are known, comprising conical drums that receive a cotton fleece and cantilever mounted on a carrier that is fixed and fixed while winding the next drum, which is rotated from a carding machine. The switching of the drums in such devices is usually done manually.

The proposed device automates the switching operation of the drums of a similar apparatus. In order to carry out periodic rotation of the shaft carrying the drums, it has a flip with a load, which is freely attached to the shaft, turned into a vertical position by a cam gear that sits freely on the same shaft and continuously rotates, and after transshipment through the vertical position, the shaft locking and arrival are successively released interaction with a ratchet stuck on the same shaft in order to turn it at an angle between adjacent drums.

FIG. 1 shows a front view of an apparatus with a drum switching device mounted thereon; FIG. 2 is a cross-section of the apparatus and device according to the aircraft and ACD of FIG. 1 and a partial side view of the apparatus of FIG. 1, in FIG. 3 is a front view of a part of the apparatus of FIG. one.

The device, connected to the frame of the carding machine with maintenance screws, is mounted on the horizontal shaft 3, by turning in the bearings 2 of the bed 7, supported by the rollers S on the corner rails 9 located along the carding machines. On the shaft 3 there are rigidly mounted holders 6 of cantilever axes 4 separate drums 5 of conical shape, which take on themselves cotton wool from the carding machine in turn. The coil is the drum facing the penner K of the carding machine, the fleece from which is removed by the roller L (or the comb) and fed to the horizontal forming drum 5, which interacts with the spring-loaded rolling pin M.

The winding drum rotates around axis 4 with gear 7, rigidly

connected to its face and engaging with gear 7, extending from a penyer carding machine.

Periodically turning the shaft J with the drums 5 at an angle between their axes 4 is carried out by shifting 75 with a load on the end freely attached to the shaft 3. The flip is raised to a vertical position, rolls over it and falls down, releasing the latch 22 holding the shaft 3 fixed position and turning the ratchet 75, stuck on the shaft 3.

The jumper 75 is controlled by a continuously rotating gear 77 with a cam t2 fcg. 3), free-sitting on & Af 3 and driven by the gear system from Penier carding machine in such a way that during the winding time of one warp, gear 7 7 made one revolution. T6 and 77 dogs are rigidly fixed on roller 18, pivotally fixed in perekidka 75. Dog 77 is pressed by spring W in direction to shaft 3 and is designed, firstly, for interacting with cams a, obliquely on either side, beating a ratchet 7J fixed on shaft 3, and, secondly, to interact with the teeth of the /, // and /// of the same ratchet, equipped with adjusting screws 74. Reversing 75, transshipped by cam 72 of gear wheel 77 through the vertical position, is kept from further falling by dog 7 (5 , the recess on the sleeve which includes the tooth of the cam 7 2, and is released when the pawl 77 meets one of the cams a, b, b turning the pawl 77 with the roller 18 until the pawl 16 is disengaged from the cam 72. The washer 20 tightly seated on the hub 75 interacts with the roller 23 of the latch 22, withdrawing it from one of the three sockets of the disk 27 fixed on the shaft 3. A further fall of the transfer 75 from the load causes a twist (ratchet 13 on the action of the pawl 77

on the screw 14 of the ratchet corresponding to the teeth /, //, /// 13. The pawl 77 is disengaged from the ratchet tine by a tooth of the cam 72 of the gear 77 when it is rotated through a certain angle, and the cam tooth will again enter the notch of the dog 16 bushing 16. Spring 26 presses the latch 22 to the disk 27.

To rotate the shaft 3 manually, you must first remove the retainer 22 from the slot of the disk 27, use the pedal 25 connected to the retainer by the lead 24.

The flat spring 27 absorbs the flap 75 when interacting with its load.

Subject invention

Claims (2)

1. A device for switching the drums winding the bases of the shaft boots from the fleece from the carding machines, characterized in that, to carry out periodic rotation of the shaft 3 carrying the drums 5, a 75 with a load is put on the shaft freely mounted on the shaft with the cam 72 77, freely sitting on the same shaft and continuously rotating, and after transshipment through a vertical position, successively releasing the locking pin of the shaft 3 and coming in contact with the ratchet 13 stuck on the same shaft, pour it at an angle between adjacent drums. 2. The form of the device according to claim 1, characterized in that the toggle 75 is provided with dogs 77 and 16 rigidly mounted on a platen in it, the first of which, spring-loaded to the shaft 3, is designed to interact with one of the cams a, 6 into the ratchet 7J before disengaging from the reversing gear 77 to rotate the washers 20 on the shaft 3, removing the retainer 22 from the slot 27 of the disk 27 rigidly mounted on the shaft 3, and the second 16 for adhering to one of the teeth /, //, / // ratchet 13.  G " 1 |, A.; A.
