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. When the production equipment moves inside and outside the detection area of ​​the multi-optical axis photoelectric sensor, no stop signal is output to stop the production equipment every time the production equipment moves outside the detection area, but the floating shielding function and the shielding monitoring function work. The detection processing unit has a floating muting function and a muting monitoring function, and enables or disables the floating muting function and the muting monitoring function according to the signal received by the receiving unit. When at least one of the optical axes is always in the shaded state, the number of the beams in the shaded state is greater than the preset maximum number of beams. The detection signal output function, the shielding monitoring function is in the shaded state of the beams A function to output detection signals even when the number is less than the preset minimum number of beam axes.

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...
