Abstract
The invention relates to a safety light curtain sensor without a dead zone, which comprises a light projector, a light receptor, a machine tool, an output line and two extension modules. The extension modules are arranged at the bottoms of the light projector and the light receptor respectively and are in internal connection with circuits of the corresponding light projector and light receptor; and the output line is positioned on the outer side edges of the extension modules. The detection dead zone is effective eliminated and the safety performance of the light curtain sensor is greatly improved by adding the extension modules and changing the outgoing direction.
Description
Technical field
The present invention relates to a kind of safety control system of lathe, particularly a kind of safety light curtain sensor of non-blind area.
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 use problem 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; the light curtain sends alarm signal; equipment quits work immediately, and the light curtain plays a protective role.But traditional light curtain sensor adopts cabling in the raised floor mostly; the thickness and the mounting bracket that add upper end cover; the first road light of light curtain sensor is very big from the distance of light curtain sensor bottom; this segment distance of some occasion that uses in actual installation is exactly the blind area; promptly detect less than the zone, cause the light curtain sensor possibly can't protect fully the person even cause danger.
Summary of the invention
The present invention be directed to present light curtain sensor and have the blind area, easily produce the problem of potential safety hazard, proposed a kind of safety light curtain sensor of non-blind area, effectively eliminated the detection blind area.
Technical scheme of the present invention is: a kind of safety light curtain sensor of non-blind area, comprise light projector, light-receiving device, lathe, output line, two spreading modules, the spreading module is contained in the bottom of light projector, light-receiving device respectively, spreading module and corresponding inner connection of light projector, light-receiving device circuit, output line is positioned at the outer side edges of spreading module.
Bright dipping place of described spreading module is built-in with lens.
Beneficial effect of the present invention is: the safety light curtain sensor of a kind of non-blind area of the present invention, and increase the spreading module and changed outlet direction, effectively eliminated the detection blind area, improved the security performance of light curtain sensor greatly.
Description of drawings
Fig. 1 is the use schematic diagram of traditional light curtain sensor;
Fig. 2 uses schematic diagram for the safety light curtain sensor of non-blind area of the present invention;
Fig. 3 is the safety light curtain sensor shape assumption diagram of non-blind area of the present invention.
The specific embodiment
The use schematic diagram of traditional as shown in Figure 1 light curtain sensor, to the light of first road, the light curtain bottom of forming by light projector 1 and light-receiving device 2, very big detection blind area is arranged from lathe 3 table tops, hand can be invaded fully, and the light curtain sensor can't detect and send alarm signal, can cause the Personal Risk.
The safety light curtain sensor of non-blind area uses schematic diagram and shape assumption diagram shown in Fig. 2,3, the light curtain sensor of this non-blind area adopts output line 4 side outlet methods, spreading module 5 is contained in light projector 1 and position, light-receiving device 2 floor detection blind area, realize inner the connection with the light curtain sensor, for the light beam that prevents to increase shines lathe 3 table tops, spreading module 5 adopts lens 6 to focus on increases light beam.
The present invention adopts side outlet and movable spreading module to increase a branch of light in the detection blind area of former smooth curtain sensor, and a table top of disembarking is no more than 5mm, has effectively eliminated the blind area, has improved the security performance of light curtain.
