Motor is controlled by controller when material to stop working.
For example, power-off protection mechanism may include an infrared distance sensor and control by taking infrared distance sensor as an example
Device, which can be set on limited block or connecting plate, for obtaining between limited block and connecting plate
Range data.Controller is connect with infrared distance sensor, is driven with the range data control obtained according to infrared distance sensor
The motor of motivation structure works or stops working.
Specifically, controller receives range data acquired in infrared distance sensor in real time.Assuming that 152 phase of connecting plate
The distance between limited block 155 and connecting plate 152 value are first threshold when being stationary state for pin shaft 153, in a kind of implementation
In mode, whether the acquired range data of controller judgement is changed compared with first threshold, if changing, really
Lock part 157 releases the locking to connecting plate 152, if not changing, illustrates that connecting plate 152 is still with respect to pin shaft 153
Locking.Alternatively, in another embodiment, controller also may determine that whether acquired range data is greater than the first threshold
Value, if so, determining that latch fitting 157 relieves the locking to connecting plate 152.
When controller determines that latch fitting 157 is released to the locking of connecting plate 152, illustrate that connecting plate 152 is rotated, i.e., around
Pin shaft 153 rotate, while also illustrating that pusher pawl 15 receives biggish resistance, got stuck, therefore controller control report
Alert device sounds an alarm, and controls motor 131 and stop working, to be conducive to protect pusher pawl 15 and pushed away material.Work as control
Device determines that latch fitting 157 still carries out locking to connecting plate 152, then controls the normal work of motor 131.
