As shown in Figure 1, blowing self-locking device of the present invention is arranged on the complete machine of discharging device, and discharging device forms primarily of electric cabinet 8 and blowing compound spiral arm 9, and electric cabinet inside is provided with controller and controls the motor of blowing compound spiral arm 9 rotation.Blowing self-locking device of the present invention is arranged in blowing composite cantilever 9.
As shown in Figure 2, a kind of compound blowing self-locking device, comprise blowing spiral arm 1, blowing pivot shaft 4, air-expanding shaft 2, current colector 7 and electric cabinet 8, described blowing spiral arm 1 drives air-expanding shaft 2 to carry out blowing, cylinder 3 is equipped with respectively separately in the two ends of described blowing spiral arm 1, air cylinder connecting rod 11, cylinder slide connecting rod 5 and opto-electronic pickup 10, a mounting hole is offered in the centre of described blowing spiral arm 1, described blowing pivot shaft 4 is passed and is fixed by bearing from described mounting hole, described current colector 7 is set on described blowing pivot shaft 4, described blowing pivot shaft 4 is connected on described electric cabinet 8 by bearing.
Wherein blowing pivot shaft 4 penetrates blowing mesopore, supports blowing spiral arm 1 and rotates; Two cylinders 3 are arranged on two of blowing spiral arm 1 respectively, cylinder slide connecting rod 5 and air cylinder connecting rod 11 intert respectively blowing spiral arm 1 two through hole in, an opto-electronic pickup 10 has been installed respectively inside cylinder slide connecting rod 5, opto-electronic pickup 10 is connected to the current colector 7 on blowing pivot shaft 4, and current colector 7 is by connection power control system.
Further, described blowing spiral arm 1 two ends respectively offer a tie rod holes, and described air cylinder connecting rod 11 freely can be stretched by described tie rod holes.
Further, described opto-electronic pickup 10 is photodiode; Described controller is programmable logic controller (PLC).
Further, described current colector 7 carries out Signal transmissions with described opto-electronic pickup 10 and described controller respectively.
Further, described blowing spiral arm 1 two ends respectively offer a through hole, and described cylinder slide connecting rod 5 is slidably mounted in described through hole by overlapping 6 with the connecting rod of its interference fit.
As shown in Figure 3, uniform 3 grooves of air-expanding shaft lock portion 2a circumference, axial uniform 3 projections on the relevant position of connecting rod cover inwall, the two locks cooperation in cylinder slide link work process.
As shown in Figure 4, when discharging device normally works, the projection 13 that the groove 12 of air-expanding shaft circumference and connecting rod overlap inner ring is in the state of locking.
Concrete blowing auto-lock process is as follows:
When described cylinder 3 air inlet, described cylinder slide connecting rod 5 drives described connecting rod cover 6 to stretch to away from described air-expanding shaft 2 direction, described opto-electronic pickup 10 is arranged on the position close to described electric cabinet 8 in the direction of extension of described cylinder slide connecting rod 5, when cylinder slide connecting rod 5 moves to described opto-electronic pickup 10 position place, induced signal is transferred to described controller by described current colector 7 by opto-electronic pickup 10, described controller sends instruction and cuts off the electricity supply, now described cylinder slide connecting rod 5 stops stretching, and described blowing revolves the back of the body 1 and stops operating.
When described cylinder 3 stops air inlet, described cylinder slide connecting rod 5 drives described connecting rod to overlap 6 to shrink near described air-expanding shaft 2 direction, shrinks when putting in place, and the projection 13 that groove 12 and the described connecting rod on described air-expanding shaft 2 surface overlaps inside matches to merge and locks.
Wherein, opto-electronic pickup adopts photounit as the sensor of detecting element.First it convert measured change to the change of optical signal, then converts optical signal to electric signal further by photounit.Opto-electronic pickup is that the change by the change of light intensity being converted to electric signal realizes controlling.
In the present invention, opto-electronic pickup adopts photodiode.The external form of photodiode is the same with general diode, and when unglazed photograph, it is the same with general-purpose diode, and counter-current is very little, is the dark current of photodiode; When there being illumination, current carrier is excited, and produces electron-hole, is called photocurrent carrier.Under the effect of external electric field, photocurrent carrier participates in conduction, and form the counter-current more much bigger than dark current, this counter-current is called photocurrent.The size of photocurrent is directly proportional to Illumination intensity, so just can obtain on load resistor with Illumination intensity change and the electric signal of change.
Use procedure of the present invention:
When machinery normally runs, air valve is closed, and cylinder slide connecting rod 5 draws in, pins air-expanding shaft 2, and under the driving of motor, blowing spiral arm 1 drives air-expanding shaft 2 to carry out the motion of rotation blowing.
When upset is reloaded, open air valve, allow cylinder 3 air inlet, cylinder slide connecting rod 5 outwards stretches, and now can take off air-expanding shaft 2 and reload.
In order to ensure overturn reload time air-expanding shaft on material can not throw off and fall down, when cylinder slide connecting rod 5 outwards extends to opto-electronic pickup 10, opto-electronic pickup 10 passes the signal to rapidly current colector 7, controller is passed the signal along to by current colector 7, power cut-off shuts down by motor, now cylinder slide connecting rod 5 stops stretching, and blowing spiral arm 1 also stops operating, and reaches self-locking object.
Blowing self-locking device of the present invention, by the setting of photoelectric sensor and current colector, makes this device have the control system that can automatically stagnate, discharging frame is overturn in safe range, do not allow material fall.Be configured with circuit control system in addition, when cylinder charge, cylinder axis can outwards stretch, and drives cylinder slide connecting rod outwards to stretch, and now cylinder slide connecting rod drivening rod cover departs from air-expanding shaft, is convenient to loading and unloading.When cylinder slide connecting rod outwards extends to opto-electronic pickup, opto-electronic pickup can pass the signal along to current colector, and current colector passes the signal along to controller again, and disconnect blowing rotating machine, motor shuts down, and reaches the object of self-locking.The effect avoid and injure operating personal, played safety guard-safeguard.
The present invention is apparent relative to the advantage that prior art possesses, and specifically has following several respects:
1, the present invention is outwards stretched by optoelectronic induction automatic controlling system cylinder slide connecting rod, and make air-expanding shaft be unlikely to come off, material can not tumble injury.
2, the opto-electronic pickup newly installed additional, current colector, power control system, constitutes a complete automatic discharging upset lock control devices, serves safety guard-safeguard effect;
3, this invention drops into little, easy and simple to handle, successful, can protective material not impaired, personnel also can be protected not injured.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
