Abstract
The utility model relates to an anticollision protection device for a welding and assembling workshop plat chain outlet. The anticollision protection device comprises through-beam photoelectric switches arranged on two sides of the plate chain outlet, and a proximity switch arranged on the lateral side of a roller bed, mounting space between the through-beam photoelectric switches and the proximity switch is larger than length of a detected sledging body, and signal output ends of the through-beam photoelectric switches and the proximity switch are directly connected with an input module of a PLC (programmable logic controller) through an electric cable or connected with an input module on a field bus and then connected to a main control PLC through the field bus. The anticollision protection device has the advantages of being quick in detection, convenient in mounting, simple in debugging, high in reliability and good in expandability.
Description
Technical field
The utility model relates to a kind of anti-collision protection device for car production, especially a kind of skid body anti-collision protection device that is applied in the workshop plate chain travel line outlet that is welded.
Background technology
Plate chain outlet Anti-bumping protection, for the normal operation of plate chain line and the normal production in workshop, has important effect.Tradition Anti-bumping protection is only by the full bit switch of plate chain Increasing exports, and in the time that band car skid body triggers full bit switch, when front, roller bed has car occupation time, and plate chain is out of service, to prevent skid body collision, sees accompanying drawing 1.But in the time that skid body is failed correct energizing signal on roller bed, the skid body on plate chain just likely can bump against skid body on roller bed.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome current Anti-bumping protection, and a kind of anti-collision protection device that can effectively be applied in the workshop plate chain outlet that is welded is provided, and ensures the normal operation of equipment and the normal production in workshop.
According to the technical solution of the utility model; the described anti-collision protection device that is welded the outlet of workshop plate chain comprise be arranged on both sides, plate chain exit correlation type photoelectric switch, be arranged on the approach switch of roller bed side; described correlation type photoelectric switch and approach switch installing space are greater than detected skid body length; correlation type photoelectric switch and the signal output part of approach switch are directly connected the load module of a PLC by cable; or load module on connection fieldbus, then be connected to main control PLC by fieldbus.
Described correlation type photoswitc comprises a pair of emission part and acceptance division, and relative is arranged on outside plate chain, and emission part and acceptance division are all placed in screened housing, and described screened housing is opaque, only reserves the window that transmits and receives of photosignal.
Described approach switch is arranged on roller bed side by mounting bracket, and the height of approach switch and skid body maintain an equal level.
Described correlation type photoelectric switch and approach switch installing space should be slightly larger than detected skid body length, such as large 0.1～1 meter.
Advantage of the present utility model has:
1. easy to detect: can, by adjusting the location gap of two switch rooms, to be applicable to the skid body Anti-bumping protection of different length.
2. Installation and Debugging are convenient: only need a pair of photoelectric switch and an approach switch to debug.
3. reliability is high: adjust and corresponding logical relation safe and reliable guarantee skid body safety distance by the switch position.
4. extended pattern is good: not only can be used for the normal Anti-bumping protection using, also can be used for detecting the abnormal connection between adjacent skid body.
Above, at this kind of anti-collision protection device of plate chain Increasing exports, can be safer, actv. protection is normal produces.
Brief description of the drawings
Fig. 1 is the switch arrangement figure of common collision avoidance system.
Fig. 2 is switch arrangement figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1, shown in 2, plate chain exports basic physical construction and comprises plate chain equipment 1 and roller bed 2, and switch is installed has full position to detect approach switch 3, roller bed occupy-place approach switch 4, roller bed deceleration approach switch 5 and the roller bed approach switch 6 that puts in place.As shown in Figure 2, the newly-increased correlation type photoelectric switch 7 of the utility model and approach switch 8.
The utility model comprise be arranged on plate chain 1 both sides, exit correlation type photoelectric switch 7, be arranged on the approach switch 8 of roller bed 2 sides, described correlation type photoelectric switch 7 with approach switch 8 installing spaces to be slightly larger than skid body 9 length as excellent (as being greater than 0.1～1 meter of skid body length).Correlation type photoelectric switch 7 is directly connected a PLC(programmable logic controller (PLC) with the signal output part of approach switch 8 by cable) load module, or connect the load module on fieldbus, then be connected to main control PLC by fieldbus.
Described correlation type photoswitc 7 comprises a pair of emission part and acceptance division; relative plate chain 1 outside that is arranged on; start to enter roller bed 2 scopes for detection of skid body 9; emission part and acceptance division are all placed in screened housing; prevent that workman from damaging unintentionally switch or false triggering on-off signal; described screened housing is opaque, only reserves the window that transmits and receives of photosignal.Described approach switch 8 is arranged on roller bed 2 sides by mounting bracket, and for detection of the complete disengaging plate chain 1 of skid body 9, the height of approach switch 8 and skid body 9 maintain an equal level.
For Anti-bumping protection, when correlation type photoelectric switch 7 continues to detect signal, and when after this this signal changes, think and detect when front sled 9 departs from correlation type photoelectric switch 7, now, in PLC, plate chain of set goes out car signal.In the time that this plate chain goes out the maintenance of car signal, if when correlation type photoelectric switch 7 signals change again, being judged to be rear car has shock risk, now, and the operation of stop board chain.When approach switch 8 detects after signal intensity, judge that plate chain goes out car and completes, plate chain can resume operation.Because installation site is only slightly larger than a sled length, therefore, this device can carry out the judgement of Anti-bumping protection accurately and rapidly.
This device, except can be used for Anti-bumping protection, can also detect the stacking phenomenon between skid body, avoids two skid bodys to link.Synchronous signal by correlation type photoelectric switch 7 and approach switch 8 triggers, and judges that abnormal connection occurs two skid bodys, and stop board chain 1 moves, and makes two skid bodys can safe separating, avoids occurring other contingencies.
