Description
Technical field
The invention belongs to technical field of textile machine, and in particular to a kind of anti-overflow protective device of high speed injection multi-arm,
Electrical synchronizer for spraying multi-arm at a high speed, in order to control circuit.
Background technology
High speed injection multi-arm be disposed on various high-performance jets, on water-jet loom for weaving plain weave, twill, satin weave
Or the shedding mechanism of facoone, fell is adjusted by phase device.If reversed without using phase device,
The tissue of front can not come out；If synchronous handle is not transferred to rotating forward, wrong flower equally will produce.Before, generally by
Manually mode pulls synchronous handle, later, when high speed injection multi-arm is gradually applied on air-jet loom, starts to use
Air synchronizing device drives synchronous handle to rotate.Air synchronizing device needs to use air cylinder, however when high speed injection multi-arm
When on water-jet loom, then air cylinder can not be used, limit the applicability that high speed sprays multi-arm in this way.The applicant it
" high speed sprays the electrical synchronizer of multi-arm " that the Chinese invention patent Authorization Notice No. CN102998984B of preceding application is introduced,
It realizes use of the high speed injection multi-arm on water-jet loom, improves adaptability, reliability that high speed sprays multi-arm.The dress
It sets in use, synchronous handle rotation is driven by motor, is stopped when encountering travel switch, however travel switch is sometimes
Due to shaking, adjusting not in place or damage etc., motor main circuit can not be cut off in time, so as to cause asking for motor rotation blockage
Topic.Motor rotation blockage refers to motor when rotating speed is 0, still a kind of situation of output torque.Power factor (PF) pole when motor rotation blockage
Low, locked rotor current reaches as high as 7 times of rated current, therefore can cause to seriously endanger.In addition, control circuit repeat circuit is normally opened
The operating current of contact can also become larger, and when beyond specified operating current, the contact of relay will be burned.Relay contact one
Denier is burned, and corresponding electric control circuit will lose original function, and motor is made no longer synchronous handle to be driven to be rotated further.
In view of above-mentioned prior art, the applicant has made beneficial design, technical solution described below be
It is generated under this background.

Open positive contactor MSM coils one end of other end connection loom of contact J2D.CN13 in Fig. 4 is connecing in loom electric cabinet
Line is arranged, and wherein SF indicates to rotate forward the positive rotaring signal inputted when button is pressed, and SR indicates the reversion letter inputted when reversion button is pressed
Number.Positive rotaring signal inverts contactor MSR normally-closed contacts by loom and accesses control circuit, and reverse signal is rotated forward by loom and contacted
Device MSM normally-closed contacts access control circuit.
Please continue to refer to Fig. 1 and Fig. 2, the operation principle of the present invention is illustrated.
When loom powers on, the automatic positive operations of the motor M, and synchronous handle is driven to run to limit switch LSF
Position at, then, since limit switch LSF is closed, relay J2 coils J2A and relay J5 coils J5A obtain electric, make relay
Device J2 normally-closed contacts J2C is disconnected, and motor M is out of service, at this point, the relay J2 normally opened contacts J2D in control circuit is closed, is made
The conducting wire 120 for being connected to loom rotating forward signal input part is connected with the conducting wire 120F for being connected to loom rotating forward contactor coil one end, is permitted
Perhaps loom forward direction is run.When synchronous handle is at the position of limit switch LSF, the normally opened contact J5B of relay J5 is closed, when into
When one step presses the reversion button of loom, motor M starts to invert, and synchronous handle is driven to stir.The present embodiment is due to increasing
Relay J5 so that motor M must rotate forward in place and stop after, could be inverted, thus, it is possible to prevent travel switch due to
It shakes, adjust the reasons such as not in place or damage, caused motor rotation blockage, electric current in the case where main circuit could not be cut off in time
Situations such as excessive and relay contact is burnt out.During stirring, since limit switch LSR is not operating, loom at this time
Reversion button be although pressed, but loom still will not act.The reason is that, if loom acts at this time, due to
Synchronous handle not yet reaches the position reversely stopped, it will causes to recklessly spend line phenomenon, and this is not allowed to.Only work as motor
M go to make to a certain degree the gear of synchronous handle reversely in place when, limit switch LSR is just acted, and then makes relay J3 coils
It being obtained with relay J6 coils electric, on the one hand, relay J3 normally-closed contacts J3C is disconnected, and motor M is made to shut down, on the other hand, control
Relay J3 normally opened contacts J3D in circuit processed is closed, and is made the conducting wire 121 for being connected to loom reverse signal input terminal and is connected to loom
The conducting wire 121R for inverting contactor coil one end is connected, and after this both threads is connected, the reversing button of loom begins to send out at this time
The effect of waving.When on loom rotating forward button or arm button press when, situation is just contrary to the above, and details are not described herein again.
