Description
Technical field
The present invention relates to a kind of anti-overshoot control devices of moving link.
Background technique
With master controller, have Displacement Feedback and in the mechanical mechanism determined under moving condition, driven member is dynamic in original
It is run according to certain rules under the driving of part.The motion state of driving link is controlled by driving link control device, and master controller sends letter
Number control driving link control device, displacement sensor feedback displacement signal is to master controller.When necessary, master controller is dynamic according to original
The displacement signal of part or driven member sends starting, acceleration, deceleration or stop signal under conditions set and fills to driving link control
It sets.It when driven member is run under some speed, is moved in suitable range by controlling driven member, avoids being more than that it is suitable
Confining part is damaged after motion range or other adjacent components are damaged.If master controller cannot obtain correctly
Displacement signal, then its can not correctly send control signal give driving link control device；If master controller and driving link control fill
The communication set goes wrong, then driving link control device is unable to get correctly control signal.Above situation can all cause driven
The movement of part is uncontrollable, brings damage to mechanism.
For example, collapsible form is directly fixedly connected with vertical compression cylinder piston rod in injection molding machine vertical compression type mould closing mechanism,
Make the reciprocating motion of speed change degree under the driving of vertical compression oil cylinder.Vertical compression oil cylinder is controlled by hydraulic valve, and master controller is by sending control letter
Number give hydraulic valve control oil cylinder.The displacement sensor being mounted on component issues collapsible form displacement signal；Master controller receives
Displacement signal simultaneously calculates speed, by sending control signal to hydraulic valve to control collapsible form.In collapsible form toward vertical compression
When oil cylinder direction is mobile, under some speed, it must slow down in certain position until stopping completely.If master controller cannot connect
By correct displacement signal, collapsible form cannot slow down and be finally stopped in correct position, and collapsible form moves at this time
Overshoot, as a result damages vertical compression oil cylinder or adjacent component.

The effect for playing cutting Bit andits control circuit in time, so that driven member emergent stopping, avoids further resulting in damage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the better embodiment of the anti-overshoot control device of moving link of the present invention.
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the present invention is described further:
Referring to Figure 1, the present invention relates to a kind of anti-overshoot control device of moving link, better embodiment includes control
Device 27, relay 26, position detector 31, displacement sensor, driving mechanism 30 and driving link 21.
Relay 26 includes first group of stationary contact 1,4, second group of stationary contact 5,8, movable contact 9,12 and electromagnetic coil 14；The
One group of stationary contact 1,4 is separately connected the no-voltage output end and control terminal of controller, and second group of stationary contact 5,8 phases are shorted；Dynamic touching
Point 9,12 is all connected with driving mechanism 30；One end of electromagnetic coil 14 is grounded, the other end link position detector of electromagnetic coil 14
The other end of 31 one end, position detector 31 connects a DC power supply VCC；Driving mechanism 30 connects driving link 21, driving link
