Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
Embodiment one
As shown in Figure 3 and Figure 4, this diamond segment conveying device comprises pedestal 1, cutter head positioning seat 2, motor 3, conveyer belt assembly 4 and delivery device.
Part based on pedestal 1, the parts such as cutter head positioning seat 2, motor 3, conveyer belt assembly 4 and delivery device are all according on pedestal 1.
Conveyer belt assembly 4 comprises the conveyer belt 4a of driving wheel, supporting roller and winding, and driving wheel and supporting roller are positioned on pedestal 1, and conveyer belt 4a is tensioned and conveyer belt 4a is horizontally disposed with.The main shaft of motor 3 is connected with driving wheel.Cutter head positioning seat 2 is positioned at the side of conveyer belt assembly 4, and cutter head positioning seat 2 is fixed on pedestal 1.
Be provided with cutter head backer 5 above the conveyer belt 4a of conveyer belt assembly 4, cutter head backer 5 is fixed on pedestal 1; Cutter head backer 5, for stopping the diamond segment 12 on conveyer belt 4a, makes diamond segment 12 stop mobile.Whether cutter head backer 5 is provided with magnetic part and detecting has diamond segment 12 and relies on sensor 6 on cutter head backer 5; The diamond segment 12 relied on cutter head backer 5 phase can push in cutter head positioning seat 2 by delivery device.
This diamond segment conveying device control strategy comprises tape transport cutter head control strategy and delivery device pushes cutter head control strategy.
Perform tape transport cutter head control strategy and rotate forward operation for continuing to control motor 3 main shaft, make conveyer belt assembly 4 drive diamond segment 12 close to cutter head backer 5.Diamond segment 12 continues infeed conveyor belt assembly 4 by vibrating disk, motor 3 main shaft rotates forward, and then drive driving wheel rotates successively, conveyer belt 4a moves, diamond segment 12 moves, the diamond segment 12 coming forefront is stopped by cutter head backer 5, a rear diamond segment 12 is stopped by previous Buddha's warrior attendant cutter head successively, slack by the diamond segment 12 stopped.
According to by diamond segment 12 quantity that stops with need perform that to control motor 3 neatly when delivery device pushes cutter head control strategy out of service.
Execution delivery device propelling movement cutter head control strategy comprises first employing sensor 6 and detects on cutter head backer 5 whether relied on diamond segment 12; There is diamond segment 12 if cutter head backer 5 relies on, then control the reverse rotation of motor 3 main shaft and make conveyer belt 4a counter motion setpoint distance; Control delivery device again.
According to actual fed diamond segment 12 model, arrange setpoint distance neatly, setpoint distance is generally 5 ~ 20 ㎜.After motor 3 main shaft reversely rotates, the diamond segment 12 only coming forefront is inhaled on cutter head backer 5 by magnetic part, all the other diamond segments 12 all move with after conveyer belt 4a, come spacing between the diamond segment 12 of forefront and adjacent diamond segment 12 equal with above-mentioned setpoint distance, above-mentioned setpoint distance numerical value can ensure that the diamond segment 12 coming forefront is separated completely with adjacent diamond segment 12.
Magnetic part is permanent magnet 7, and the quantity of permanent magnet 7 is two, is separately positioned on the both sides of sensor 6, like this in order to improve diamond segment 12 stress balance; Guarantee fund's diamond tool bit 12 is attracted on the stability on cutter head backer 5.According to actual conditions, permanent magnet 7 can adopt electromagnet to replace.Adjust the magnetic force of electromagnet or permanent magnet 7 according to diamond segment 12 model of conveying neatly, ensure that the diamond segment 12 only coming forefront is inhaled on cutter head backer 5 by magnetic part.
If push sensor 6 in cutter head control strategy process at execution delivery device not monitored diamond segment 12 and rely on cutter head backer 5, then can control to perform tape transport cutter head control strategy, after operation setting-up time, as 10 seconds, if cutter head backer 5 relies on and has diamond segment 12, continue to perform delivery device and push cutter head control strategy, otherwise then report to the police.
Delivery device comprises and pushes cylinder 8 and push 9, and the cylinder body pushing cylinder 8 is fixed on pedestal 1, pushes 9 and is fixedly connected with the piston rod of propelling movement cylinder 8.Controlling delivery device is that the piston rod controlling propelling movement cylinder 8 stretches, and piston rod stretches out to drive and pushes 9 motion, and then diamond segment 12 is pushed in cutter head positioning seat 2.
Embodiment two
The present embodiment with the structure of embodiment one and principle substantially identical, basic something in common no longer burden describes, different place is only described, different place is: delivery device comprise push cylinder 8, push 9, pinch roller 10 and pinch roller 10 to be pushed to directly over cutter head positioning seat 2 and the pinch roller that can compress the diamond segment 12 on cutter head positioning seat 2 drives cylinder 11, pushing the cylinder body of cylinder 8 is fixed on pedestal 1, pushes 9 and is fixedly connected with the piston rod of propelling movement cylinder 8; Pinch roller drives the cylinder body of cylinder 11 to be fixed on pedestal 1, and pinch roller 10 is positioned at pinch roller and drives on the piston rod of cylinder 11.The horizontal pinch roller that pinch roller drives cylinder 11 to comprise serial connection drives cylinder 11a and vertical pinch roller to drive cylinder 11b.
This delivery device is adopted can effectively to prevent diamond segment 12 single head be pushed in cutter head positioning seat 2 from tilting; Especially prevent from tilting in fan-shaped diamond segment 12 single head as depicted in figs. 1 and 2; Namely improve diamond segment 12 be positioned at cutter head positioning seat 2 state uniformity and meet subsequent handling processing request.
Controlling delivery device is that first level of control pinch roller drives cylinder 11a and vertical pinch roller to drive the piston rod of cylinder 11b to stretch out successively, pinch roller 10 is positioned at directly over cutter head positioning seat 2, and between pinch roller 10 and cutter head positioning seat 2 bottom surface, spacing is slightly less than diamond segment 12 height.The piston rod controlling to push cylinder 8 again stretches, and piston rod stretches out to drive and pushes 9 motion, and then diamond segment 12 is pushed in cutter head positioning seat 2; In the process, diamond segment 12 compresses by pinch roller 10, and then avoids diamond segment 12 single head to tilt.Last level of control pinch roller drives cylinder 11a and vertical pinch roller to drive the piston rod retraction of cylinder 11b, and pinch roller 10 is positioned at the side of cutter head positioning seat 2, avoids parts such as pinch roller 10 grade to affect follow-up crawl diamond segment 12 operation and carries out.
