SU50606A1 - Adaptation to spinning vaters to cut off the roving and stop the spindle if the thread breaks - Google Patents

Description

The proposed adaptation to spinning mounts is intended to shut off the feeding of the roving into the feeding cylinders at the time of thread breakage and at the same time stop the spindle, in order to prevent the carbon from burning into the winding and to eliminate the wrapping on the cylinders and rollers.

This facilitates the work of water-skaters, who are relieved of unnecessary work to stop the spindle when refilling the broken thread and from stuffing professional calluses on the palm of the left hand.

In the device, a system of pivotally connected levers is used, one of which is hooked and rests on a thread. When the thread breaks, a corresponding rotation of the lever system occurs, as a result of which the roving is clamped by the toothed plate, and the drive block is disengaged from the spindle.

In FIG. 1 is a side view of an attachment to a spinning watering for stopping the roving and stopping the spindle; and FIG. 2 is a vertical section of the spindle drive.

On the upper longitudinal angular section of the link of the bed of the spinning vater, a square / is fastened, on which a plate with a hole 3 is attached for the passage of the roast. Bracket 4 is fixed to bracket 2, at the bent ends of which the centers holding axis 5 with lever 6 are screwed so that the axis at the centers can easily rotate. On axis 5, plate 7 is reinforced, having a small, notched cusp at the end. In plank 2, near the hole for the rovings of ukrei. There is no second curved steel plate S, which also has a notch in its upper end portion. Notches on the plates are designed to increase friction when clamping rovings between them. Kosi 5, except for the lever 6, is attached to the rod 9 as a counterweight. Toward the end of the lever 6 there is attached a ha 10, the second end of which is connected to the crank lever 7 /. The crank lever // is integral with the axle 12 held in the centers screwed into the folded ends of the bracket / 3, fastened on the bar 14, which in turn is fastened to

longitudinal connection vater. On the same strap / the second bracket 15 is strengthened, in which, like that of bracket 13, the centers holding the axis with the lever / are screwed into the curved tail ends / (. The plate / 7 is hinged to the second end of the crank lever there is a prong 0.75 mm deep, resting on the burner / 6. On the lever 16 on one axis with the plate // the lever 19, having a longitudinal slot at the end, is fixed. It is connected to the lever 16 TLC, which at the junction in the slot can freely move in the longitudinal direction. To the second end of the lever 19 with Dolny-cutoff hooked hook 20, the curved end of which surrounds filament roving frame at the place of its passage in the thread eyelet Vatera strap.

To automatically stop the spindle, a cranked lever 21 is attached to the crankshaft, the second end of which is articulated with the fork 22, the carrier rollers 23. The fork axis is held in the centers screwed into the bent ends of the bracket 24 fastened on the bar 25 that is bolted to the top spindle timber.

The spindle block 26 is freely mounted on the spindle, and to reduce friction as it spins (during the spindle stop), a ball bearing is inserted inside the block. From longitudinal movement down the block is held by a ring 27, in the upper part it is tapered and tightly worn on a spindle; the sharpening angle corresponds to the conic sharpening of the ball-holder clip.

In its upper outer part, the block has an annular sharpening, into which a helical spring 28 is inserted into one curl (shown in dotted lines in the drawing). The ends of the spring are bent at a right angle — one up, the other down. The end of the spring, bent down, enters the hole drilled in the upper part of the block, and the end bent upwards enters the hole drilled in the disk 29 located on top of the block. Spring 28 has the purpose to soften the blow when you turn on the spindle on the working stroke. Next to the spring hole, a steel pin 30 is screwed into the disk 29,

Above the disk 29 a washer 31 is rigidly mounted on the spindle, the bottom part having a protrusion 0.5 ml above the pin 30. The disk 29 is in contact with the end face of the protrusion of the washer 31.

In the washer 31, two holes were drilled diametrically through which the studs 32 secured in the disk 53 pass freely. The length of the studs 32 is made in such a way that at a lower position between them and the disc 29 there is a gap of about 0.5 mm. The disk 33 fits freely on the spindle and with the help of a fork 22 with rollers 23 can be raised and lowered to a height up to the sleeve 34, which is rigidly worn on the spindle. The lifting height of the disk 55 is made in such a way that, with the upper position, its pins 32 go deeper into the washer 5 / bottom at a distance of about 0.5 mm in order to eliminate their blows against the pin 50. During operation of the water heater, the rotate hook 20 is set so that its curved end envelops the roving thread and keeps it from moving horizontally backwards. The lever 19 connected to the hook 20 at this time is in such a position that the hinge connecting the lever 19 to the lever 16 is approximately in the middle of the longitudinal notch of the lever 19. In this case, the plate 17 is set so that its tooth abuts in the rack 18, and the free end is above the hinge connecting lever 19 with lever 16. When the thread is broken, hook 20 is released from support by its roving; at the same time, the axis with the lever 16, due to the advantage of the rod on the axis serving as a weight, will turn in the direction of rotation clockwise, the lever 19 together in the hook 20 will move to the left. When the lever 16 is rotated, the hinge connecting lever 19 to it, the end of plate 17 will rise, and the tooth will come out of engagement with the support leg 18, as a result of which plate 17 will also move to the left and turn the crank lever // on the axis. When turning it, the thrust of 10 will move up, turn the axis with the lever 6, and at the same time the plate 7 fixed on the axis, which when turning turns into a position against the plate 8, as a result of which the roving between these plates is clamped, it will break and feed will stop rovings in a pair of nutritious rollers, which prevents it from winding on the cylinder of a vater.

At the same time, when the lever is rotated, the second hinge 21 attached to it will also move up, and the fork 22 will also lift with it. With the help of rollers 25 the disk 33 will be raised to the height of the sleeve 34, tightly worn on the spindle. Pin 32 will come out of engagement with pin 30,

reinforced in disk 29, after which the connection of block 26 with washer 31 is interrupted, the spindle will stop and the block will rotate on the spindle at idle.

The subject matter of the invention.
