Be equipped with a fixed beam 144, fixed beam 144 is horizontally disposed, receiving terminal 142 be arranged at fixed beam 144 and with transmitting terminal 140 one by one
It is corresponding.It is appreciated that in other embodiments of the invention, photoelectric sensor device can be reflective photoelectric sensor, it connects
Receiving end 142 and transmitting terminal 140 are respectively positioned between the column 120 of upstream, and the receiving terminal 142 of the present embodiment should be replaced with correspondingly
Reflecting plate.
In order to enable 140 height of transmitting terminal of laser sensor arrangements accurately to adjust, one of connecting portion 138 from
One ranging induction module 150 is provided with by end, ranging induction module 150 can measure itself apart from 180 upper table of lower section strip
The distance in face, is transmitted to controller, controller can be according to ranging induction module 150 and photoelectric sensor device by this distance signal
The difference in height of transmitting terminal 140 calculate the spacing distance of transmitting terminal 140 and 180 upper surface of strip, which also just determines
The precision of detection, when light path with parallel strip 180 relatively when, precision height；Be relatively distant from rear precision it is low compared with.It should manage
Solution, transmitting terminal 140 and the distance of load plane 112 can also be obtained according to 180 THICKNESS CALCULATION of strip of advance typing controller.
Before testing, when adjusting 140 height of transmitting terminal, driving mechanism 130 drives carrying component to move down, and works as ranging
After induction module 150 detects that distance reaches pre-determined distance, controller control drive division 136 stops driving.In the present embodiment,
Ranging induction module 150 is infrared range-measurement system, and in other embodiments of the invention, ranging induction module 150 can also be super
The other types such as acoustic ranger.
Fig. 5 is the circuit connection diagram of each equipment in the embodiment of the present invention.Incorporated by reference to Fig. 1 and Fig. 5, in this embodiment, control
Device includes PLC, electric machine controller 164, computer 160, signal acquisition module 162.PLC is used to control feed device to carry out feeding
Or stop feeding, and corresponding enabling signal and stop signal are produced, it passes through signal acquisition module 162 and computer 160
It is electrically connected, computer 160 can receive enabling signal and stop signal.Electric machine controller 164 is installed on 120 side of machine pillar
Face, is electrically connected with drive division 136.Drive division 136 is electrically connected with electric machine controller 164, computer 160 at the same time.Electric machine controller
164 can manually or automatically control two ways：Specifically, 136 work of drive division can be controlled by electric machine controller 164
Make, drive leading screw 135 to move, adjust the height of photoelectric sensor device；Also it can be sent and ordered by the software systems of computer 160
Control drive division 136 works.Photoelectric sensor device is also to be electrically connected by signal acquisition module 162 with computer 160.Ranging sense
Answer module 150 to be electrically connected with computer 160, the distance of ranging induction module 150 to strip 180 is real-time transmitted to computer
160, when dropping to certain altitude, computer 160 can send instruction automatically, stop the running of drive division 136, stop declining.
Computer 160 is also associated with a warning device 170, when photoelectric sensor device detects that strip 180 is bent, meter

When starting continuous production, interval time T, PLC produces an enabling signal, controls feed device by 180 edge of strip
Conveying direction produces a stop signal, the length strip of conveying to conveying preset length L in stamping die 110, then PLC
180 be a punch section.Institute interlude T is used for processing strip 180, such as punching press.It should be appreciated that in some other reality
Apply in example, when the strip 180 of processing is shorter, for example once only strip 180 is opened in punching press one, operating personnel can also adopt every time
With manually adjusting position of the strip 180 in stamping die 110, and the height of photoelectric sensor device is readjusted every time, at this
In the case of sample, without using PLC feed device can be controlled to carry out friction feeding.
S2, when computer 160 reads enabling signal, system confirm start at this time for feeding, computer 160 starts to read
The signal of photoelectric sensor device is taken, and is judged：If light path is blocked, photoelectric sensor device sends the first signal, then it represents that
Strip 180 has buckling in detection zone, and computer 160 sends instruction to serial ports, and control warning device 170 sends police
Report, and control feed device to stop feeding；Light path is not blocked, then photoelectric sensor device continuously sends out secondary signal, it is represented
The strip 180 that region is monitored in feeding process keeps smooth, then continues to read the signal of photoelectric sensor device, continues to sentence
It is disconnected.It should be appreciated that the first signal and the second signal here are the distinguishing two kinds of signals of tool, such as the first signal and the second letter
Number be respectively high level and low level.
S3, when computer 160 reads stop signal, system confirm terminate at this time for feeding, system stop judgement is
No that 180 buckling of strip can occur, computer 160 terminates the signal-obtaining to photoelectric sensor device, stops judging, press machine
100 start punching parts.
After interval time T, PLC re-emits enabling signal, and control feed device carries out feeding, photoelectric sensor device
Continue to operate, computer 160 reads the information of photoelectric sensor device, is judged, so in cycles.Second wheel and follow-up inspection
If the thickness of strip 180 does not change in survey, without being adjusted to the height of photoelectric sensor device.
In conclusion the press machine of the embodiment of the present invention includes being used to convey the feed device of strip, for accepting strip
Undertaking plane, for detect accept plane on strip flat conditions photoelectric sensor device and controller.Photoelectric sensing
Device is produced above load plane and the light path of load plane interval pre-determined distance, when strip production of the conveying on load plane
When life bends (including arch upward or tilt) and stops light path, photoelectric sensor device can give controller to transmit a signal, control
Device can control feed device to stop feeding.Such press machine can detect certain length on load plane by light path
Whether strip occurs bending and deformation, and detection range is wide, precision is high, and can be automatically stopped movement support when detecting bending
Follow-up production safety, saves substantial amounts of manpower.
The strip bend detection method of the present invention includes the strip that control feed device conveys preset length to load plane,
Control photoelectric sensor device generation above the load plane and with the light path of load plane interval pre-determined distance；In course of conveying
In, if light path is blocked, sends alarm signal and/or control press machine is shut down；In course of conveying, if light path does not hinder
Disconnected, then after the strip conveying of preset length, control feed device stops conveying strip.The detection method using light path come
The smooth of strip is detected, can accurately detect whether the strip in preset length section bends, and can be according to being
It is no to bend to select to carry out follow-up process：Alarm or shutdown are bent, prevents from ensureing subsequent production safety；Do not occur curved
Bent then continuation feeding, punching press.The accuracy of detection of this method is high, scope is big, ensure that product quality and equipment safety.
