Embodiment Construction

[0057] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. The perspective view of the appearance of the light-projecting (or light-receiving) cylinder involved in the present invention is as follows: figure 1 shown. As shown in the same figure, the multi-optical axis photoelectric sensor according to the present invention has beams 10 for light projection and light reception which are arranged oppositely when in use.

[0058] The container of this cylinder 10 has a columnar container body 101, an end cap 102 blocking one end opening of the columnar container body, an end cap 103 blocking the other end opening, and a front panel 104 blocking the front side. As will be described in detail later, the columnar container body 101 and the end caps 102 and 103 are made of metal and have a substantially U-shaped cross section. The front panel 104 adopts a plastic plate transparent to the light used. The sensor as...

Abstract

The invention provides a photoelectric sensor with a plurality of optical axes which has width of a corresponding dangerous area and a diameter of a minimal detecting object and can flexibly change the length of a cylinder for light projection and receiving, the number of optical shafts, the distance between optical shafts, etc. A light projection and receiving device series comprises an optical module series, a common conducting wire and a conducting wire between adjacent modules, wherein, the optical module series only consists of a plurality of optical modules which are arranged into a row, the optical module consists of an optical system of an optical shaft 1, a light projection circuit of the optical shaft 1 and a primary trigger corresponding to a shift register which are connected into an integral body, the common conducting wire is corporately connected with a module for light projection from one end to the other end of a module series for light projection, the conducting wire between adjacent modules is only connected with an adjacent module for light projection, each optical module forming the optical module series is respectively connected with a belt-shaped cable; therefore, the conducting wire between adjacent modules is used to connect the trigger inside the adjacent optical module subordinatively to form the shift register. Therefore, the ordinal operation of each optical module of the optical module series is formed according to the data sent by the shift register in sequence.

Description

technical field [0001] The present invention relates to a multi-optical axis photoelectric sensor for monitoring human bodies etc. that enter a dangerous area. In particular, it is possible to flexibly change the length of the light emitting and receiving cylinder according to the width of the targeted dangerous area, the diameter of the minimum detected object, etc. , the number of optical axes and the distance between optical axes, etc. Background technique [0002] This kind of multi-optical axis photoelectric sensor is well known. It has a light-emitting cylinder made by accommodating the light emitter row in a cylindrical container, and a light-receiving cylinder made by accommodating the photoreceiver row in the cylindrical container. The light-receiving cylinders are arranged at appropriate intervals so that the light-emitting and receiving surfaces face each other, and a light curtain for object detection is formed between the light-emitting and receiving cylinders. ...
