Description
Technical Field
The utility model relates to a safe light curtain especially relates to a movable safe light curtain.
Background
Modern factory has become more and more important to the safety protection of workman or machine, and safe photoelectricity is used more and more extensively, and traditional regional protection type photoelectricity need use special stand fixed mounting in the position of protection area during normal work, for guaranteeing safety, the light curtain installation finishes, and the position can not change at will, and the support of safe light curtain passes through the fix with screw on ground or equipment, and in case the support is fixed, the protection area of light curtain just can not change. If the protection area of the light curtain is changed, the support needs to be detached and fixed by punching again, which is very inconvenient for the production site that the protection area needs to be changed frequently.
Disclosure of Invention
In order to solve the problem, the utility model provides a movable safety light curtain provides a mobilizable device of safety light curtain. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a movable safety light curtain, includes dolly and light curtain, the dolly include the chassis, the lower part on chassis is provided with the universal wheel, the light curtain set up on the chassis of dolly, the light curtain includes illuminator, photic ware, light curtain signal acquisition circuit, position signal acquisition circuit, signal processing circuit, control circuit and state display circuit, position signal acquisition circuit be connected with the universal wheel through the encoder, light curtain signal acquisition circuit, position signal acquisition circuit are connected with control circuit through signal processing circuit, control circuit carries out logic processing and judges, control signal output, state display circuit is connected with control circuit for instruct current position information of dolly and light curtain state.
Further, the position signal acquisition circuit comprises a displacement signal acquisition circuit and an angle signal acquisition circuit.
Compared with the prior art, the utility model discloses following beneficial effect has: the dolly can conveniently arrange the light curtain through the universal wheel removal, and the back is launched to the light curtain, and the controller real-time supervision dolly position information, in case change, safe light curtain can the shading locking to inform the controller disconnection output, reach safety protection's purpose.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of the external structure of the present invention;
FIG. 2 is a schematic diagram of the circuit control structure of the present invention;
FIG. 3 is a schematic diagram of the circuit principle structure of the present invention;
in the drawings: 1. the device comprises a trolley, 2, a light curtain, 3, a chassis, 4 and universal wheels.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to fig. 1, fig. 2 and fig. 3 and the specific embodiments.
As shown in attached figures 1, 2 and 3, the movable safety light curtain comprises a trolley 1 and a light curtain 2, wherein the trolley 1 comprises a chassis 3, universal wheels 4 are arranged on the lower portion of the chassis 3, the light curtain 2 is arranged on the chassis 3 of the trolley 1, the light curtain 2 comprises a light emitter, a light receiver, a light curtain signal acquisition circuit, a position signal acquisition circuit, a signal processing circuit, a control circuit and a state display circuit, the position signal acquisition circuit is connected with the universal wheels 4 through an encoder, the light curtain signal acquisition circuit and the position signal acquisition circuit are connected with the control circuit through the signal processing circuit, the control circuit carries out logic processing judgment, outputs control signals, and the state display circuit is connected with the control circuit and used for indicating the current position information and the light curtain state of the trolley 1.
Further, the position signal acquisition circuit comprises a displacement signal acquisition circuit and an angle signal acquisition circuit.
The utility model discloses a theory of operation and working process as follows: when the safety light curtain protection device is used, the safety light curtain is pushed to the position of an area needing to be protected, after the light curtain is debugged to be light-on, the light curtain switch is started, the light curtain is in a normal protection state, and once a person breaks into the protection area, the light curtain immediately informs the control circuit to break an output signal. In the use process, once the position of the light curtain (the position of the trolley) is changed, the light curtain can be shielded and locked immediately, and the operator is prompted to confirm the protection area again through display.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
