The detection device of the rotating part has the advantages of being low in cost, convenient to install, simple in use and easy to operate.
Description
Technical field
The present invention is specifically related to a kind of pick-up unit of rotary part.
Background technology
During current industrial automation is produced, wishes whether can be in halted state in the axle kind equipment of rotary motion state in automatic decision source, and do not need the detection speed of rotary part and the equipment in direction or method.As sprayed tubulose target installations in spraying, adopt spray gun motionless, the mode that target rotates sprays, and just needs pipe target not stop to rotate, will report to the police and arrestment work, otherwise will scrap target if meet accident when stopping., only needing to judge that the occasion whether turning axle stops uses, there is price high, installing complicated in current detection method many employings speed pickup, rotary encoder, camera and monitor etc., is a kind of waste greatly.
Summary of the invention
The technical problem to be solved in the present invention, is the pick-up unit providing a kind of rotary part.
The present invention is achieved in that a kind of pick-up unit of rotary part, comprises an induction mechanism, a plurality of proximity switch and a PLC; Described induction mechanism comprises a rotating shaft, a rotating disk and a plurality of magnetic detection head, and described rotating shaft and rotating disk interlock are arranged; Described a plurality of magnetic detection head is all located on an end face of rotating disk, and a plurality of magnetic detection head is laid along the even circumferential being the center of circle with the center of rotating disk; Described a plurality of proximity switch is all arranged in opposite directions with described magnetic detection head, often this proximity switch be all positioned to the subpoint on rotating disk described in circumferentially, and the arc length often between adjacent two proximity switches is not equal to the arc length between adjacent two magnetic detection heads; Described PLC has a plurality of timer, and described a plurality of timer and a plurality of proximity switch connect one to one.
Preferably, the quantity of described proximity switch is two.
Preferably, the quantity of described proximity switch is three.
The invention has the advantages that:
1, low, the simple installation of cost, use are simple, easy to operate;
2, the quantity of magnetic detection head and proximity switch according to actual conditions sets itself, can improve when proximity switch is many and detect fiduciary level and time of fire alarming;
3, when speed adjusts, changeable proximity switch quantity ensures accuracy of detection.
Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the pick-up unit of a kind of rotary part of the present invention.
Embodiment
Refer to shown in Fig. 1, a kind of pick-up unit 100 of rotary part, comprise an induction mechanism 1, a plurality of proximity switch 2 and a PLC (not shown); Described induction mechanism 1 comprises rotating shaft 11, rotating disk 12 and a plurality of magnetic detection 13, and described rotating shaft 11 and rotating disk 12 link and arrange; Described a plurality of magnetic detection 13 is all located on an end face of rotating disk 12, and a plurality of magnetic detection 13 is evenly laid along the circumference O being the center of circle with the center of rotating disk 12; Described a plurality of proximity switch 2 is all arranged in opposite directions with described magnetic detection 13, often this proximity switch 2 be all positioned to the subpoint on rotating disk 12 described in circumferentially, and the arc length often between adjacent two proximity switches 2 is not equal to the arc length between adjacent two magnetic detection 13; Described PLC has a plurality of timer (not shown), and described a plurality of timer and a plurality of proximity switch 2 connect one to one.The quantity of described proximity switch 2 is preferably two or three.
Referring again to Fig. 1, described rotating shaft 11 is connected with rotary part (not shown), rotate along with rotary part, the timer internal of the open and close signal control PLC controller of proximity switch 2, the quantity according to PLC timer internal determines to arrange how many proximity switches 2.In the present embodiment, proximity switch 2a, proximity switch 2b be corresponding control timer T0, timer T1 respectively, specific works principle: when rotating shaft 11 along with rotary part rotates, two timers starting PLC control carry out timing, when proximity switch 2a senses a magnetic detection 13, reset with regard to action control timer T0, leave timer T0 after this magnetic detection 13 until proximity switch 2a and restart timing; Equally, when proximity switch 2b senses a magnetic detection 13, reset with regard to action control timer T1, leave timer T1 after this magnetic detection 13 until proximity switch 2b and start timing again; Namely when proximity switch 2a, proximity switch 2b do not sense magnetic detection 13, timer T0, timer T1 just always in timing, until reach default timing.After rotary motion stops, no matter have at least a proximity switch 2 can not sense any one magnetic detection 13 in any position, when the timing time of timer T0 or timer T1 reaches preset value, PLC can send reports to the police or exports control signal, thus detects that the rotary motion of rotary part stops.The time of presetting is the shortest time that can detect that rotary motion stops, and proximity switch 2 action is shorter for interval time, and sensitivity is higher.
In addition, when only two proximity switches 2, a proximity switch 2 is had at least can not to sense any one magnetic detection 13 when halted state; When there being more than three proximity switches 2, at least ensureing that proximity switch 2 can not sense any one magnetic detection 13, otherwise cannot detect that rotation status stops.
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
