Abstract

The utility model relates to a yarn broken-end detector applied on a ring spinning frame, which comprises a sensor and a signal processor, wherein the sensor is composed of a thermally-sensitive member used as a primary element; the signal processor is connected with the sensor. When the sensor is arranged on a spinning frame to spin, the temperature of positions where are heated by friction is cooled down comprising the contacting positions of yarn and guide wires, and travel rings and ring travelers, after the ends of the yarn are broken. The sensor transforms temperature scale into electrical signals, and the electrical signals are sent to the signal processor. The signal processor can send out signals to prompt within 8 to 16 seconds. The utility model has the advantages of few sensor element, small volume, low cost and rapid reaction; the utility model does not influence the operation of machines operated by tenders or cleaning work, and enhances the pastille watching efficiency of the tenders.

Description

The Yarn break checkout gear

1. technical field

The utility model relates to a kind of Yarn break checkout gear of being connected on the ring throstle, with the fine spining machine signal detecting and measuring apparatus of being applied in textile industry.

2. background technology

The spun yarn spinner's of textile mills major responsibility is to check and the processing broken end, and checks that wherein broken end has accounted for quite a few time.Especially when spinning dark yarn, because yarn color and environment contrast are not strong, broken end is checked more difficult, needs the spinner to touch with hand, can make broken end whether judgement with feel.

For addressing this problem, at present external fine spining machine generally adopts the patrolling apparatus for detection of breaking of yarn detecting the spinning broken end situation of each ingot position, and supplies with central signal processor analytic record and send signal guiding spinner and handle broken end.

As Swiss Patent CH601093 a kind of device is disclosed, in order to detect the broken end situation of each ingot position.It moves past each ingot position by a sensor that moves through each next door, ingot position along a guide rail, so that contactlessly accept the signal of telecommunication, should touring sensor induce the turn signal of the steel traveler of each ingot position, and signal is delivered to the central signal processor by the traction lead according to the magnetoelectric induction principle.

The deficiency that said apparatus exists is: a guide rail must be set before the ring rail of spinning machine move to realize the touring of sensor.This guide rail is all made troubles to spun yarn operation and cleaner.And because the touring mode of its machinery, occur to broken end from broken end and detect and need the long period, can not in time send signal.

3. summary of the invention

The purpose of this utility model provides a kind of Yarn break checkout gear that is different from touring detection mode, and can each ingot position of fine spining machine be detected in real time, in time feeds back broken end information, and simple in structure, easy for installation, and cost is lower.

It is that the sensor that primary element constitutes reaches the signal processor that is connected with lead with described sensor that the spinning end breaking checkout gear of the utility model design comprises by temperature-sensitive element, described is that the sensor that primary element constitutes is arranged on the position of the heat that rubbed when fine spining machine spins with temperature-sensitive element (thermistor or other temperature sensitive devices), comprises the position that yarn and twizzle, rings contact with steel traveler.When fine spining machine start just is in the beginning when spinning the stage, because frictional heating rises this position temperature value rapidly.The temperature value of this point changes slowly when normally spinning thereafter.And in a single day broken end takes place, owing to lost friction of motion and because spindle rotates the wind that produces this position temperature has been descended rapidly.Sensor is transformed to the signal of telecommunication by temperature-sensitive element with temperature value and delivers to processor, and signal processor is made the judgement that this ingot is in normal spinning or broken end state according to difference variation in the unit interval.If broken end takes place, signal processor can send signal prompt in 8～16 seconds.

The utility model Yarn break checkout gear can install easily in different frictions and rise on the hot spot because its primary element volume is less.The sensor element of Gou Chenging is few thus, and volume is little, does not hinder keep off a car operation or cleaning.And with low cost configurable on each ingot position because of it, accurately promptly the status signal of each ingot position is spread out of immediately.Thereby make signal processor make judgement, ingot efficient is seen by the unit that has improved the spinner fastly.

5. the specific embodiment

The rings form different according to ring throstle, the utility model adopt different two kinds of installation sites and version (seeing Fig. 2, Fig. 3); The 3rd kind of form then is the inside (Fig. 4) that directly temperature-sensitive element is placed the tubulose twizzle.

Embodiment 1.As shown in Figure 2, sensor 1 is installed in the inboard of ring rail 2, and its primary element thermistor 5 is installed in ring holder clamping place 4, and is close to the oily wire casing cell wall of rings 3, and is fixed by the securing member of clamping ring holder.

Embodiment 2.As shown in Figure 3, sensor 1 is installed in the inboard of ring rail 2, and its temperature-sensitive element 5 is close to the outer wall of rings 3 by 10 tops of spring, and spring 10 is fixed on the box body of sensor 1.
