Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same reference numerals in the drawings indicate the same or corresponding parts.

[0032] figure 1 The appearance of the multi-optical axis photoelectric sensor to which the present invention is applied is shown. In the multi-optical axis photoelectric sensor S of this embodiment, a light projector (light projecting unit) 1 and a light receiver (light receiving unit) 2 are configured as a pair. The light projector 1 has a light emitting element 11 , and the light emitting element 11 and a control board are accommodated in a housing 101 . Similarly, the light receiver 2 includes a light receiving element 21 and is accommodated in the housing 102 together with a control board. In addition, cables 101a and 102a for connection are drawn out from the lower end portions of the housings 101 and 102, respectively.

Abstract

The invention provides a multi-optical axis photoelectric sensor. For a manufacturing machine that moves in and out of a detection area of a multi-optical axis photoelectric sensor, floating blanking and blanking monitoring are activated without outputting a stop signal to stop the manufacturing machine every when the manufacturing machine moves out of the detection area. A detection processing unit performs, when at least one of the plurality of optical axes is constantly interrupted by the object, floating blanking of outputting the detection signal upon determining that the number of optical axes in an interrupted state is greater than a preset maximum optical axis number, and blanking monitoring of outputting the detection signal upon determining that the number of optical axes in an interrupted state is smaller than a preset minimum optical axis number, and activates or deactivates the floating blanking and the blanking monitoring based on the signals received by the signal reception unit.

Description

technical field [0001] The invention relates to a multi-optical axis photoelectric sensor. In particular, the invention relates to a multi-optical axis photoelectric sensor with floating shielding function and shielding monitoring function. Background technique [0002] In general, a multi-optical axis photoelectric sensor includes a light projecting unit in which a plurality of light projecting elements are arranged in a row, and a light receiving unit in which the same number of light receiving elements as the light projecting elements are arranged in a row. The light receiving element is arranged to face the light projecting element, and the light emitting element and the light receiving element form an optical axis. In this way, the detection area is formed from one end to the other end of the plurality of optical axes arranged in a row. [0003] The light projecting part makes each light projecting element emit light. The light receiving unit takes out a light receiv...
