Abstract
The utility model relates to a safety light curtain sensor capable of omnidirectional displaying. A light curtain sensor light projector upper end cover and a light curtain sensor light receptor upper end cover are mounted on a light curtain sensor light projector and a light curtain sensor light receptor respectively; yellow indicator lights are mounted in four directions of front, rear, left and right in the middle of the light curtain sensor light projector upper end cover; and red-green indicator lights are mounted in four directions of front, rear, left and right in the middle of the light curtain sensor light receptor upper end cover; and the indicator lights are connected with an indicator light flashing alarm circuit. In the utility model, the indicator lights are mounted on four sides of the light curtain sensor light projector upper end cover and four sides of the light curtain sensor light receptor upper end cover, and the indicator light flashing alarm circuit for fault state of the safety light curtain sensor is additionally arranged, so that a user can conveniently and clearly observe the working state of a light curtain at any moment. The utility model changes the displaying method of a traditional safety light curtain sensor, enables the working state of the light curtain to be monitored at any moment and provides great convenience for customers in use.
Description
Technical field
The utility model relates to a kind of safety control system of lathe, especially a kind of sensor that is used for machine tool safety protection.
Background technology
Along with the high speed development of Chinese industrial automation, a large amount of press machine equipment are brought into use, and the safety problem that thereupon produces more and more receives publicity.The latest national standards that came into effect equivalent IEC61496-1/2 in 2004 " the quick protector of mechanical electric safety electricity " GB/T 19436.1/2-2004; in order to protect operator's safety, safety light curtain sensor becomes the electric quick protector (ESPE) that press machine equipment must be equipped with.And about the demonstration problem at work of safety light curtain sensor; in present known technology; safety light curtain sensor is installed in the front of press machine or working robot's periphery; when the people enters the deathtrap because blocked the light curtain; equipment quits work immediately; and the working station indicator of light curtain generally only is contained in and throws; on the parallel position, the light curtain protection zone that light-receiving device forms; and only do logical light and the demonstration of blocking two states; in actual the use operator whether only just can observe the present duty of light curtain at certain special angle normal, very inconvenient when debugging smooth curtain sensor safe in utilization.Fig. 1 is that the indicator lamp of conventional security light curtain sensor shows schematic diagram; indicator lamp 5 is contained in and light curtain light projector 1; on the parallel position, the light curtain protection zone that light curtain light-receiving device 2 forms; and only do logical light and the demonstration of blocking two states, the operator can't observe light curtain current working state in the workbench front.
Summary of the invention
The utility model is whether normally the display mode that will solve existing safety light curtain sensor exists and can only just can observe light curtain duty technical problem at special angle, and a kind of safety light curtain sensor of comprehensive demonstration is provided.
The technical scheme of taking for solving the problems of the technologies described above is: a kind of safety light curtain sensor of comprehensive demonstration, comprise light curtain sensor light projector, light curtain sensor light-receiving device, indicator lamp, be characterized in: light curtain sensor light projector upper end cover and light curtain sensor light-receiving device upper end cover are housed respectively on light curtain sensor light projector and the light curtain sensor light-receiving device, indicator lamp is housed respectively around light curtain sensor light projector upper end cover and the light curtain sensor light-receiving device upper end cover.
Yellow indicator lamp all is equipped with in the front, rear, left and right four direction central authorities of light curtain sensor light projector upper end cover;
The red and green color indicator lamp all is equipped with in the front, rear, left and right four direction central authorities of light curtain sensor light-receiving device upper end.
Indicator lamp connects indicator lamp flicker alarm circuit.
The beneficial effects of the utility model are: the utility model is installed with signal light all at the four sides of the upper end cover of safety light curtain sensor light projector and light-receiving device, increase the indicator lamp flicker alarm circuit of safety light curtain sensor malfunction in addition, allow the user make things convenient for and clearly observe the duty of light curtain at any time.
The utility model has changed the display packing of conventional security light curtain sensor, makes light curtain duty monitor at any time, greatly facilitates client's use.
Description of drawings
Fig. 1 is that the indicator lamp of conventional security light curtain sensor shows schematic diagram;
Fig. 2 is that indicator lamp of the present utility model shows schematic diagram;
Fig. 3 is an appearance structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described in further detail; but present embodiment is not limited to the utility model; every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
Consult Fig. 1; Fig. 1 is that the indicator lamp of conventional security light curtain sensor shows schematic diagram; indicator lamp 5 is contained in and light curtain light projector 1; on the parallel position, the light curtain protection zone that light curtain light-receiving device 2 forms; and only do logical light and the demonstration of blocking two states, the operator can't observe light curtain current working state in the workbench front.
Fig. 2 is that indicator lamp of the present utility model shows schematic diagram, comprises light curtain sensor light projector 1, light curtain sensor light-receiving device 2, light curtain sensor light projector upper end cover 3, light curtain sensor light-receiving device upper end cover 4, yellow indicator lamp 6, red and green color indicator lamp 7.
Light curtain sensor light projector upper end cover 3 and light curtain sensor light-receiving device upper end cover 4 are housed respectively on light curtain sensor light projector 1 and the light curtain sensor light-receiving device 2, around light curtain sensor light projector upper end cover 3 and the light curtain sensor light-receiving device upper end cover 4 indicator lamp are housed respectively.
Yellow indicator lamp 6 all is equipped with in front, rear, left and right four direction central authorities at light curtain sensor light projector upper end cover 3, when light curtain sensor light projector 1 operate as normal, yellow indicator lamp 6 is lighted always, for example stop light projector etc. when light curtain sensor light projector 1 breaks down, yellow indicator lamp 6 begins flicker and reports to the police with prompting operation person.
Red and green color indicator lamp 7 all is equipped with in the front, rear, left and right four direction central authorities of light curtain sensor light-receiving device upper end cover 4, when light curtain sensor light-receiving device 2 operate as normal, show green light during light curtain have no occluder and the light curtain shows red light when being blocked, when the light curtain sensor light-receiving device 2 internal wiring fault etc. that for example breaks down, red light begins flicker and reports to the police with prompting operation person.The operator can the omnibearing light curtain current working state of observing like this.
The utility model can be when safety light curtain sensor be worked the comprehensive duty of observing the light curtain, and indicator lamp shows and increased alarm condition, makes the use hommization more of safety light curtain sensor.
