Abstract

The invention discloses an automatic-monitoring yarn guiding mechanism comprising a motor, a guiding shaft, a driving synchronous belt, a yarn guiding synchronous belt and a yarn guiding tube. The yarn guiding synchronous belt and the driving synchronous belt are arranged in parallel in a staggered mode in the vertical direction. The driving synchronous belt is driven by the motor, and the guiding shaft is arranged in parallel above the yarn guiding synchronous belt and sleeved with a sliding base. The yarn guiding tube is fixed on the sliding base connected with the yarn guiding synchronous belt through a sliding base connecting shaft. The automatic-monitoring yarn guiding mechanism further comprises at least one identification element and a monitoring device used in cooperation with the identification elements in a non-contact mode. According to the technical scheme, the abrasion degree of the yarn guiding synchronous belt can be automatically monitored, and it can be avoided that severe abrasion of the yarn guiding synchronous belt affects the normal functions of the yarn guiding mechanism.

Description

A kind of Yarn guide mechanism of automatic monitoring

Technical field:

The present invention relates to field of textile machinery, in particular to a kind of Yarn guide mechanism of automatic monitoring.

Background technology

Traditional servo yarn guide mechanism of cluster ball warping machine generally adopts ball screw pair, this kind of drive is had relatively high expectations aspect regular maintenance, and the secondary sealing of ball screw is poor, flyings are easily deposited on ball screw, cause ball nut to stop up, change accessory cost higher, and noise is larger when equipment operation.

To this, Granted publication CN202131425U, the disclosure of the invention in February 1 2012 Granted publication day following technical scheme: a kind of yarn guide mechanism of cluster ball warping machine, it comprises motor, the axis of guide, transmission Timing Belt, guide Timing Belt and yarn-guide tube, the upper and lower parallel misalignment setting of described guide Timing Belt and transmission Timing Belt, described transmission Timing Belt passes through driven by motor, the described axis of guide is set in parallel in the top of guide Timing Belt, on the axis of guide, be equipped with slide, on described yarn-guide tube fixing slide carriage, described slide is connected with guide Timing Belt by slide connecting axle.This invention has been owing to having adopted toothed belt transmission, the noise while having reduced equipment operation, and the maintenance cost of equipment has reduced greatly compared with the kind of drive of ball screw pair, the quality of having restrainted ball forming while simultaneously having improved the package of yarn ball.

But, there is following technical problem in foregoing invention: described slide connecting axle and the constantly contact friction of guide Timing Belt, can cause guide Timing Belt to be worn, and then may there is the danger that guide Timing Belt ruptures, even if guide Timing Belt does not rupture, also may cause slide connecting axle and the loose contact of guide Timing Belt and affect the movement of slide on the axis of guide.The technical problem that more than may occur all can affect the normal operation of Yarn guide mechanism, reduces the operating efficiency of Yarn guide mechanism.

Summary of the invention

Technical problem solved by the invention: a kind of device is provided, and it can realize a kind of automatic monitoring, and can not cause the unexpected fracture of guide Timing Belt or heavy wear and affect the normal function of Yarn guide mechanism.

The invention provides following technical scheme: a kind of Yarn guide mechanism of automatic monitoring, comprise motor, the axis of guide, transmission Timing Belt, guide Timing Belt and yarn-guide tube, the output of described motor is connected with one end of transmission Timing Belt, one end of the other end of described transmission Timing Belt and guide Timing Belt is connected with synchronizeing wheel shaft work, the other end of described guide Timing Belt is fixed on synchronous wheel shaft in the frame of a cluster ball warping machine, the upper and lower parallel misalignment setting of described guide Timing Belt and transmission Timing Belt, the described axis of guide is set in parallel in the top of guide Timing Belt, the two ends of the axis of guide are individually fixed in described frame, on the axis of guide, be equipped with slide, on described yarn-guide tube fixing slide carriage, described slide is connected with guide Timing Belt by slide connecting axle.Also comprise embed at least one discriminating element in described guide Timing Belt, with the contactless monitoring device being used in conjunction with of described discriminating element, described discriminating element and monitoring device are used in conjunction with the degree of wear that can monitor guide Timing Belt.

When make discriminating element expose due to the wearing and tearing of guide Timing Belt, discriminating element will wear and tear, and changes thus its identification function.As preferably, described monitoring device comprises that one by the oscillation circuit with a capacitor and a coil of resonant excitation, the coil that described discriminating element is short circuit.Because monitoring device comprises that one by the oscillation circuit with a capacitor and a coil of resonant excitation, thereby produce resonance signal.This resonance signal only has very little decay.But in the time being used as this oscillation circuit of coil process of short circuit of discriminating element, this oscillation circuit is loaded, thereby produces the signal having compared with short arc.When guide Timing Belt is worn, cause thus the coil exposed of short circuit out, this discriminating element is worn so.The coil of previously short circuit is damaged thus causes no longer short circuit.No longer change the signal of monitoring device at the coil impaired and no longer short circuit of monitoring device side process, can monitor by this way the degree of wear of guide Timing Belt.By technique scheme, can automatically monitor the degree of wear of guide Timing Belt, and can not cause the unexpected fracture of guide Timing Belt or heavy wear and affect the normal function of Yarn guide mechanism.

As a further improvement on the present invention, described monitoring device is arranged on the below of discriminating element.

As a further improvement on the present invention, the width of described discriminating element is less than the width of guide Timing Belt.
