Embodiment 1

[0030] A kind of propelling type lead detection light curtain and the propelling type lead detection light curtain sensing method, such as figure 1 , figure 2 , image 3 As shown, it mainly includes a signal control unit 1, one or more power propulsion units 4, guide units 2, 3 and 5, detection and induction units 7, 10 and 12, 13 and 15, limit return units 9, 11, 14, 34, 35, 36,. The limit protector 8 and the connecting wires 16, 17, 18, 19 are jointly composed, and the assembly is fixedly connected or inlaid and fixedly connected to the hollow inner cavity of the working body 6 or the outer side of the outer wall 29 of the working body .

[0031] This embodiment is applicable to the working body that the present invention moves oppositely in two directions (such as the elevator door of two-way closing door, automatic door, etc.), the working body of multi-directional closing type opposite cross movement, and the common working body that moves oppositely in other ways. A...

Embodiment 2

[0040] This embodiment is that the present invention is suitable for one-way lateral and nearly one-way lateral propulsion working bodies, such as one-way closed door elevators, automatic doors, one-way gate valves, gates, cutting machines, etc., and other one-way lateral, close to one-way Examples of laterally propelled general working bodies and machinery and equipment. Its setting and working principle are basically the same as in Embodiment 1, the difference is as follows Figure 4 , its assembly is fixedly connected or inlaid and fixedly connected to the hollow inner cavity of the working body 6 or outside the outer wall 29 of the working body, the first beam group emitter 25 and the first beam group beam 26 of the first beam group assembly 7 are set The outer wall 37 of the working body destination agreed with the working body 6 has a hollow inner cavity or is inlaid on its outer side. There is only one set of detection sensor return switches 14 in this embodiment, and t...

Embodiment 3

[0042] This embodiment is applicable to the working bodies that are unidirectionally or nearly unidirectionally propelled, such as rolling gates, die-casting machines, punches, cutting machines, and pouring machinery, as well as other unidirectionally or nearly unidirectionally propelled bodies. Examples of common working bodies and machinery and equipment. Its setting and working principle are basically the same as in Embodiment 1, the difference is as follows Figure 5 As shown, the first beam group assembly 7 and the positioning protector 8 are arranged on the fixed body 39 of the working body, and are higher than or protruding from the horizontal destination 38 of the working body. At the same time, the first beam can be canceled in this embodiment. Group assembly 7, the simplest setting can only use the second beam group beam 23 (one pair or two pairs of beam groups), or the third beam group 24 two pairs of beam groups, or the minimum three pairs of beam groups of two gro...

Abstract

The invention discloses a same-working-body moving sequential push type guide detection light curtain and a sequential push type guide detection light curtain induction method. The same-working-body moving sequential push type guide detection light curtain mainly comprises a signal control unit, more than one power push unit, a guide unit, a detection induction unit and a limiting return unit. Before and during movement of the working body, the propelling and limiting return unit positions, propels, guides and detects the detection sensing unit according to the set direction and position of the guide unit, and after the detection sensing unit is propelled to a set destination, the limiting return unit drives the detection sensing unit to return to an initial position along with the working body under the counter-acting force of the limiting return unit. And the dead-angle-free sequential push type guide detection is circularly completed. According to the method, other photoelectric waves, electromagnetic waves, ultrasonic waves and the like are adopted to achieve the induction effect of the method, and the method is suitable for common working bodies which move in a one-way, two-way, multi-way, sector-angle and annular circulation mode and mechanical and equipment working bodies which have safety factors in stamping, collision and operation.

Description

[0001] Field: [0002] The invention relates to a detection and induction light curtain and a method thereof, in particular to a detection and induction light curtain that advances and moves in sequence with a working body and an induction method for a leading detection and induction light curtain that advances and moves in sequence. [0003] technical background: [0004] The existing known light curtain sensors are fixed and all adopt beam groups arranged in parallel to form a sensing light curtain so as to sense and identify the working state of the light curtain. For example: the Chinese invention patent with the announcement number CN201010150301.4 discloses: a vertical elevator light curtain and a vertical elevator light curtain detection method, the transmitting and receiving units of the light curtain are fixed at both ends of the car door, Use the emission timing to sense and identify the working state of the light curtain. Its essence is to fix the transmitting and r...
