Description
Technical field
The utility model relates to a kind of fault automatic detector responsive to material fracture when transporting filament shape material, especially a kind of yarn detector that is used for doubling winder.
Background technology
The yarn detector that is used for the detection of doubling winder yarn at present mainly contains photoelectric type yarn detector and electrostatic yarn detector, and it is subjected to the influence of external factor easily to the environmental requirement height.Such as, dust, humidity and magnetic field, electric field all can influence yarn detector and accurately work.Therefore, the poor reliability of photoelectric type yarn detector and electrostatic yarn detector is easy to generate error signal, and influences normally carrying out of work.
The utility model content
The utility model will solve above-mentioned prior art and be subject to the external factor influence, and the problem of poor reliability provides a kind of lever transmission mechanism work that utilizes, the yarn detector that reliability is high.
The technical solution of the utility model is such: a kind of yarn detector, comprise housing, be located at the broken yarn detection agency on the housing, the signal generator of signal and the signal processor that this signal is handled take place in the state variation that causes because of broken yarn according to the broken yarn detection agency, described broken yarn detection agency comprises the lever of support yarns and the adjustment piece that at least one pair of cooperates by magnetic field; Described adjustment piece comprises with lever action and the motion block of changes of magnetic field takes place and decide piece.Motion block with decide the interblock attractive force that is magnetic.During work, yarn is supported on the lever, if yarn is in the state that is transported continuously, the tension force of yarn and magnetic attracting force combined action make lever be in state of equilibrium in lever, and yarn just has consistent all the time tension force.If yarn breakage, the yarn tension that acts on lever disappears, the lever lack of equilibrium, motion block moves to deciding piece under the effect of magnetic attracting force, cause the variation in magnetic field, signal generator will be according to the variation generation signal (such as being switched on or switched off circuit) in this magnetic field, and signal processor is further handled this signal, the output control signal responds the corresponding site of doubling winder.Like this, the yarn of fracture just can in time be detected.In order not influence motion block and the magnetic field of deciding piece, housing and other parts are made with non-magnet material.
Described lever has fulcrum and support end that is connected in the fulcrum two ends respectively and the swinging end of being located on the housing; Described motion block is permanent magnet and is located on this swinging end.The support end support yarns is established motion block on the swinging end, motion block moves with swinging end.Support end, swinging end and fulcrum three form a whole lever construction, and three parts on this lever can be to be assembled, and also can be a shaft bending is formed.Because lever principle, the motion of support end will cause the swing of swinging end, thereby motion block is moved.
Described housing is provided with locking piece and locking piece sliding tray, and this locking piece is positioned at the locking piece sliding tray and has the limiting section of locking lever.Do not needing that yarn is carried out broken yarn when surveying, the limiting section of locking piece can limit the swing of swinging end, and like this, lever will can not be rotated by locked; Wherein the locking piece sliding tray can prevent that locking piece from being reversed and fractures.
Described housing is provided with tension adjustment part and sliding tray, describedly decides piece and is located in the sliding tray in the mode that can slide in sliding tray under the tension adjustment part drives.The outer end of described tension adjustment part is connected on the housing, and its inner has screw thread and is positioned at sliding tray, describedly decides piece and is bolted on this tension adjustment part.In the actual detection process, owing to the not equal reason of thickness of yarn, the tension force of yarn can be different, turn this moment tension adjustment part is because the effect of screw thread is decided piece and just slided in sliding tray, thereby the distance between change and motion block, motion block changes with the magnetic attracting force (promptly putting on the power of lever swing end) of deciding interblock thereupon, and this power adapts with the tension force of yarn and keeps the balance of lever with the tension force of yarn, thereby the tension force of yarn is adjusted.
Described signal generator is Hall element or the dry-reed tube that is switched on or switched off circuit according to changes of magnetic field.Whether motion block can be in different positions respectively according to broken yarn, thereby change the magnetic-field intensity that imposes on Hall element or dry-reed tube, Hall element or dry-reed tube can be switched on or switched off circuit according to the variation of magnetic field power, make the signal processor response send control signal, action so that the corresponding mechanism of doubling winder is handled it.
Described housing is provided with yarn guiding port at the yarn place of passing.Yarn guiding port is made by high-abrasive material.
The utility model has the advantages that: the utility model adopts lever transmission mechanism to survey yarn, and is simple in structure, the reliability height; Can detect the yarn of fracture in time.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-housing, 2-yarn guiding port, 3-support end, 4-tension adjustment part, 5-decide piece, 6-sliding tray, 7-output line, 8-signal processor, 9-signal generator, 10-motion block, 11-swinging end, 12-fulcrum, 13-locking piece, 14-locking piece sliding tray.
The specific embodiment
As shown in the figure, yarn detector of the present utility model comprises housing 1, is located at the broken yarn detection agency on the housing, the signal generator 9 of signal and the signal processor 8 that this signal is handled take place the state variation that causes because of broken yarn according to the broken yarn detection agency, and the broken yarn detection agency comprises the lever and a pair of adjustment piece that cooperates by magnetic field of support yarns; Adjusting piece comprises with lever action and produces the motion block 10 of changes of magnetic field and decide piece 5 by what this magnetic field cooperated with motion block.Lever has the fulcrum of being located on the housing 12 and the support end 3 that is connected in the fulcrum two ends respectively and swinging end 11; Motion block 10 is permanent magnet and is located on this swinging end.Locking piece 13 is positioned at the locking piece sliding tray 14 on the housing, and this locking piece has the limiting section of locking lever.Housing 1 is provided with tension adjustment part 4 and sliding tray 6, decides piece 5 and is located in the sliding tray 6 in the mode that can slide in sliding tray under driving at tension adjustment part 4.The outer end of tension adjustment part 4 is connected on the housing 1, and its inner has screw thread and is positioned at sliding tray 6, decides piece 5 and is bolted on this tension adjustment part 4.Signal generator 9 is the Hall elements that produce signal according to changes of magnetic field.Housing is provided with yarn guiding port 2 at the yarn place of passing.Yarn guiding port is made by high-abrasive material.The signal of signal processor output is outwards exported by output line 7.
During work, yarn passes yarn guiding port 2 and is supported on the lever support end 3, when yarn continuously when not rupturing because yarn tension and adjust the effect of the magnetic attracting force of piece, lever keeps balance.Behind the yarn breakage, yarn tension disappears, and lever lack of equilibrium, motion block 10 move to deciding piece 5 under magnetic field force, thereby cause changes of magnetic field, and make the more close producer in magnetic field.Hall element just can be according to this changes of magnetic field output signal.Like this, the yarn of fracture just can in time be detected.
