SU1527336A1 - Arrangement for interrupting roving supply to drafting system in case of yarn beakage in spinning machine - Google Patents

Abstract

The invention relates to the textile industry and allows for improved operational reliability. On a fuse device mounted on the carrier, the guide is mounted with the possibility of moving along it perpendicular to the clamp line of the power supply pair of the exhaust device of an L-shaped strap, on which a sealing funnel is fixed. The plank is placed on the guide with its curved end to cover it, and the other end is connected with a rod connected to the core of the electromagnet. When a yarn is broken, the sensor signals the electromagnet moving the rod, which removes the bar with the sealing funnel fixed on it from the power supply pair of the exhaust device perpendicular to it and moves the eccentric lever through the eccentric. When the lever is lowered, with its curved end, it presses the roving against the guide in the area between the sealing funnel and the supply pair of the exhaust device, as a result of which it breaks off, remaining inside the sealing funnel. 4 hp f-ly, 4 ill.

Description

The invention relates to the textile industry and can be used on ring spinning machines and spinning machines.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows the device on the side of the supply pair of the exhaust device; in fig. 2 - the same, in the off position, side view; in fig. 3 the same in the working position; in fig. - device control circuit.

The device contains 1 mounted on the carrier of a machine exhaust device perpendicular to the line 2 of the clip

its feeding pair 3 has a guide in the form of a bar on which a l-shaped bar 5 is fitted with a curved end with a sheath. The bar 5 carries a sealing funnel 6 of the extracting device attached to it and is connected to the other end with means for moving it together with a sealing funnel along a guide rail having a cable 7, connected at one end to the core 8 of the electromagnet 9. The core B has a spring (not shown) for returning it to its original position. The end 10 of the strip 5 which faces the supplying solder of the exhaust device is arcuate to prevent fibers from entering the drive cylinder 11 of this pair.

The device contains a L-shaped arm 12 mounted with the possibility of pressing its folded end 13 against the guide for clamping the roar when the yarn is broken and pivotally connected with the other end 1b by means of an eccentric 17 which is freely mounted on the OSI of the 1b and opposite to the electromagnets. 7

returns the micro-toggle switch to its original position, transferring the entire device to the standby state.

When a signal is received on the elimination of a breakage, the electromagnet 9 releases the core, which, under the action of a return spring, retracts the rod 7 to the right towards the rake. T ha turns the eccentric clockwise, while the L-shaped lever 12 rises, freeing the end of the roving from the clamp. At the same time, the strip 5 is supplied to the pit line

with the latter by means of nuts 19. A pair of t-joints, together with the sealing end of the rod and the end of the lever 12 are pivotally mounted on the eccentric 17.

The control circuit of the device contains a yarn break sensor 20, which produces an automatic filling of the roving into the appliance by the hopper.

It is connected to the electromagnet 9, the signal Q along the clamping line of the power supplying pair of light bulb 21 and the micro-toggle switch 22 (Fig. +).

The device works as follows.

In the course of spinning machine operation, rover 1 passes through the sealing funnel 6, and in the exhaust device it sinks into a bow, which is twisted into a yarn. At the same time, the strip 5 together with the sealing funnel is in the position closest to the steam supply of the exhaust device (Fig. 2).

In the event of a break, an electromagnet 9 is triggered, the core 8 is pulled in, which with the help of rod 7 draws the plan 5 with the funnel 6 from the clamping line of the supply pair along the guide k. At the same time, the m ha 7 turns the eccentric 17 counterclockwise. At the same time, the L-shaped lever 12 is lowered and the end 13 presses the roving to the guide 4, as a result of which (the caller, due to the force applied by the stretching device on the side of the exhaust pair, breaks off in the area between this pair and the L-shaped lever at the same time in a sealing funnel.

At the same time, turning on the electromagnet 9 lights up the signal lamp 21, which signals the location of the yarn breakage on the machine. In order to eliminate a breakage, the worker with a microtooller 22 breaks the power supply circuit of the electromagnet 9, blocking

it happens very slowly and almost at the moment of retraction from the clamping line, the power supply pair makes a simple movement, perpendicular to the clamping line, which does not affect the performance of the device.

The micrototalker 22 is located on the valve bar of the machine, and therefore, working with it does not complicate the work of the operator. To simplify maintenance, one microtool switch controls the operation of the interrupt device to stop six spinning spindles. The signal light is located on a panel mounted on the roving frame of the machine, which provides good visual control over the operation of the machine.

The presence in the device of a means for withdrawing the sealing funnel from the feed pair allows the roving to be clamped in front of the feed clip line of the feed pair in the area freed from the funnel. The funnel moves perpendicularly to the clamping line of the feeding pair a distance longer than the staple length of the fibers. This moving does not lead to a roving tug, it freely passes through the funnel, as it is clamped at only one point in the feeding pair.

The clamping of the roving in the device takes place before it enters the exhaust device, between the roving funnel and the feed pair. This makes it easier for the latter to break the yarn sensor in order for the aforementioned refueling to clamp the supply pair, to include a false positive of the device, since after the break of the roving its cove begins to eliminate the breakage on the machine.

The funnel moves perpendicularly to the clamp line of the feed pair a distance longer than the staple length of the fibers. This movement does not lead to a jerk of the roving; it freely passes through the funnel, as it is clamped only at one point in the supply pair.

The clamping of the roving in the device takes place before it enters the exhaust device, between the roving funnel and the feed pair. This facilitates its subsequent filling in the clamp of the supply pair, since after the break of the roving its end remains in the funnel, and by simply moving it to the clamp line, the automatic filling of the roast is provided.

The design of the device ensures its reliable operation by reliably breaking the roving without delay after the arrival of a yarn breakage signal with automatic filling of the roving into the exhaust device after the elimination of the breakage of the yarn, without requiring additional costs for the supplying of the roaster. The device is located outside the exhaust device, does not block the roving frame and does not interfere with the maintenance of the machine.
