Abstract
The invention relates to a photoelectric protection device, particularly relates to a forging press photoelectric protection device and belongs to the technical field of forging machinery. At present, the existing photoelectric protection device of the forging machinery has the following shortcoming of being complex in installation, instable in performance, complex in structure and not prone to light focusing. According to the photoelectric protection device, a light projector and a light receiver are arranged in a separation mode, the structure is simple, a reflector is omitted, and system performance instability caused by external environment effects on the reflector is avoided. The light projector and the light receiver project and receive light in full area, so that light focusing is avoided. In addition, an area knowledge protection device and an alarm are further arranged on the light projector and the light receiver, so that the photoelectric protection device is safer.
Description
Technical field
The present invention relates to a kind of photoelectric protector, particularly a kind of Pressesforging photoelectric protector, belongs to metal forming machinery technical field.
Background technique
In metal forming machinery; in order to protect the safety of operator; often adopt photoelectric protector; photoelectric protector; whether general employing photoreceptor leaves hazardous area as other positions of mobile phone health of exploration operation person; if detect in one's hands and other positions not leave hazardous area; machinery does not work, and only has when deathtrap is all left at any position of operator's health, and machinery just works; at present;, there is following shortcoming in the existing photoelectric protector of metal forming machinery: installs loaded down with trivial details, unstable properties; complex structure, is not easy light.
Summary of the invention
Goal of the invention: the object of this invention is to provide simple and compact for structure, is convenient to install, stable performance, easy to light, is specially adapted to the photoelectric protector of punch press.
Technological scheme: a kind of photoelectric protector; comprise illuminator, light receiver, controller; described illuminator transmitted beam; described light receiver accepts the light beam that described illuminator sends; formed between described illuminator and described light receiver and protect light curtain; the make-and-break signal of described light curtain is sent to described controller by described light receiver, and described controller exports control signal and controls lathe.
On described illuminator and described light receiver, all correspondence is provided with top optical axis mark and bottom optical axis mark.
Described light receiver is also provided with the numbering of digital-scroll technique board for the light beam that is blocked described in showing.
Described light receiver also comprises logical shading tutorial light and shading is reported to the police.
Described light beam is that 4 bundles to 40 are restrainted, and the distance between described top optical axis mark and described bottom optical axis mark is 400 millimeters to 5000 millimeters.
Beneficial effect: illuminator and light receiver are provided separately by the present invention; structure is simple; eliminate reflector; avoid the systematic function instability because reflector causes because of external environment influence; this illuminator and light receiver are region-wide luminescence and light, avoid the trouble to light, and this external illuminator and light receiver are also provided with protected zone knowledge device; and alarm, safer.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Embodiment
As shown in the figure; a kind of photoelectric protector; comprise illuminator 1, light receiver 2, controller 3; described illuminator 1 transmitted beam; described light receiver 2 accepts the light beam that described illuminator 1 sends; formed between described illuminator 1 and described light receiver 2 and protect light curtain, the make-and-break signal of described light curtain is sent to described controller 3 by described light receiver 2, and described controller 3 exports control signal and controls lathe.
On described illuminator 1 and described light receiver 2, all correspondence is provided with top optical axis mark 4 and bottom optical axis mark 5.
Described light receiver 2 is also provided with the numbering of digital-scroll technique board 5 for the light beam that is blocked described in showing.
Described light receiver 2 also comprises logical shading tutorial light 6 and shading reports to the police 7.
Described light beam is that 4 bundles to 40 are restrainted, and the distance between described top optical axis mark 4 and described bottom optical axis mark 5 is 400 millimeters to 5000 millimeters.
In addition to the implementation, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
