According to the invention, a permanent magnet arranged on a payoff shaft is periodically close to a sensor arranged on a payoff rack to generate a pulse signal when the payoff reel rotates during paying-off, each payoff shaft is provided with the permanent magnet and the sensor, signals of all sensors are monitored and processed by a microcomputer broken line detection controller, an alarm is output if any sensor has no alternating signal in the specified time, and the machine is stopped by a switch signal of an alarm relay, and therefore product scrapping caused by no accurate identification after wire body breaking and manual misoperation is avoided.
Description
Affiliated technical field:
The present invention relates to the pick-up unit of the monofilament broken string in the wire twisting machine processing, especially can whether break by the reliable recognition monofilament.
Background technology:
At present, the monofilament burn out detection of known wire twisting machine pay off rack (like Figure of description " Fig. 1 ") has following several shortcoming:
1. the monofilament through the tension force fork is after fracture, rebounds and touches the metal sleeve that back and frame insulate, and metal sleeve and frame respectively connect an electrode; The signal that touches of two electrodes is delivered to Main Control Tank wire twisting machine is shut down, but such touching depends on the bounce of tension force fork, when producing electronics line or other thin wire cores; Tension force need be transferred very for a short time, otherwise can break monofilament, and bounce is extremely small and tension force is turned down afterwards; What cause contacting is unreliable, even can't rebound fully.
Surface of contact between metal sleeve and the tension force fork and between tension force fork and frame (frame connects an electrode, commonly used a contact be connected on the pay off rack skeleton) have a little corrosion or dirty after, all can cause losing and be electrically connected and can't report to the police.
3. be with insulating sleeve on the tension force fork, when this paying out reel does not use sleeve pipe do not left behind, pull on during unwrapping wire; But sleeve pipe is a plastic material; There are aging and expansion shrinkage phenomenon, are not easy in the time of new to be pulled, old and fall naturally because of gravity and vibration easily; Even cause the tension force fork to rebound effectively, also can't Normal Alarm.
4. mostly the metal sleeve behind several tension force forks is that the loosening back level sleeve pipe that can cause of joint loses electrical connection, and is difficult in time come to light through being connected in series on pay off rack.
5. when processing has the higher line body of insulation course or plasticity,, also produce knotting, be stuck in when causing the tension force fork to rebound on the cable-through hole not in place after the fracture because of the line body is twined by wire twisting machine even break.
6. when wire twisting machine is started shooting; Main motor is a soft start, and the rotational speed of draw drum depends on main motor speed, and master's motor does not reach before the rated speed during startup; Line body as on the paying out reel is laid particular stress at paying out reel in the heart slightly; The tension force fork can significantly rock and touch metal catheter and produce false alarm, so behaviour crewman worker often needs the Temporarily Closed break alarm function could normal boot-strap, does not open warning again and causes failing to report but be easy to again behind the normal boot-strap neglected.
7. because be that contact is reported to the police; So two electrodes can only setting between metal sleeve and the frame are closed for reporting to the police; Normal condition is for breaking off; And the line of pay off rack between wire twisting machine main body wire casing of no use or poling are often trampled or other reasons by behaviour crewman worker fixedly the time, cause line to break off after, machine can't obtain alerting signal.
8. when not needing unwrapping wire; Need insulating sleeve on the tension force fork of correspondence be left behind; Pull on again when needing unwrapping wire, pull on also very difficult assurance and can not fall down, add that the position disperses relatively; Cumbersome during setting, also bump the line body that hangs on other tension force forks disconnected easily in the operating process.
Generally speaking; Such detecting reliability is very low, and it is very high that dependency degree is kept an eye in manual work, and the Manufacturing Worker is mostly again to be that a people keeps an eye on many machines simultaneously; Carelessness is arranged slightly; Also continue to produce and cause that product scraps in a large number with regard to causing product to lack monofilament easily, the produced on-site situation also really so, scarce monofilament is scrapped and is happened occasionally.
Summary of the invention:
In order thoroughly to overcome the unreliable problem of original break alarm; Whether the present invention takes to detect draw drum and judges whether to break in rotation; Micro computer burn out detection controller in the device is followed wire twisting machine master motor automatically and is started together; Time-delay waits for that wire twisting machine master motor speed is promoted near the rotation information of gathering paying out reel behind the normal value; Sheet permanent magnet operate as normal in the micro computer burn out detection control system is to follow draw drum to rotate synchronously, if permanent magnet continuously effective in the official hour scope can detect the paying out reel broken string accurately and reliably near sensor or leave sensor and all can produce warning always; Also need not the people when payingoff speed is very slow in the start-up course for closing break alarm, thereby avoid manually-operated carelessness and cause converted products to be scrapped.
Whether the technical scheme that technical solution problem of the present invention is taked is: judge whether to break in rotation through detecting draw drum, install permanent magnet additional at former paying out reel afterbody, in Figure of description " Fig. 3 "; Effectively the opposite near permanent magnet installs proximity transducer additional; Magnet is followed paying out reel and is rotated synchronously, and during the wire twisting machine operate as normal, the rotation of permanent magnet will periodically produce alternating signal on sensor; When broken string takes place when; Paying out reel must stop, and the alternating signal on the sensor also stops thereupon, promptly continues to rest on the state of conducting or disconnection; Exceed the time range of this device qualification when arbitrary state residence time of this sensor after, promptly can output alarm.And this device has the delay working function; Though start with wire twisting machine master motor synchronous, the speed that can wait for main motor just detects after near normal speed, and this device can also be according to the radical and the position of product technological requirement setting monofilament; When changing product variety; To need only to need the paying out reel sensor of unwrapping wire to push to according to numbering toggle switch of corresponding " channel selecting " on micro computer burn out detection controller, the sensor correspondence of unwrapping wire is not closed and is got final product (like Figure of description " Fig. 4 "), and can cooperate flicker to come display working condition and alarm content through the pilot lamp various colors; The realization of this scheme; Can avoid the multiple possibility of failing to report of contact break alarm, the carelessness of also having avoided artifact to bring, duty and alarm condition come into plain view; Need not under the situation that manual work keeps an eye on the purpose of reliable and stable warning thereby reach.
The invention has the beneficial effects as follows:
Need not in the production run artificially to set and keep an eye on, whether this device just can true and reliable detection unwrapping wire process have broken string to take place, and it is good, easy to use to connect mobile type.
