Description

Technical Field

[0001] The utility model belongs to the technical field of conveying accessory equipment, and in particular relates to a touch sensing structure used for conveying equipment. Background Art

[0002] Conveying equipment is commonly used in production, including belt conveying equipment, plate conveying equipment and roller conveying equipment. Among them, roller conveying equipment is widely used due to its high conveying efficiency and large load.

[0003] With the improvement of production automation, it is often necessary to set sensors on conveying equipment to determine the position status of materials on the conveying equipment. The sensors used are usually travel switches, distance sensors and photoelectric comparison sensors. Among them, the travel switch is a contact sensor, which has a slow response speed and a relatively low life span, and cannot be used for conveying equipment with higher conveying speeds. Both the distance sensor and the photoelectric comparison sensor are non-contact sensors, both of which have the advantages of fast response speed and long service life. The distance sensor is usually set above the conveying equipment, and determines whether there is material passing by the height of the irradiation surface. Due to its own detection range, it is only suitable for the conveying of a single material. When the conveying equipment conveys materials of various sizes, it is easy to make a misjudgment; the photoelectric comparison sensor is usually set in pairs on both sides of the conveying equipment, and the position of the material is determined by detecting whether there is an obstruction between the two photoelectric comparison sensors. However, the distance between the two photoelectric comparison sensors is mostly equal to or greater than the width of the conveying equipment, and the distance is large. In many cases, the production environment is relatively messy, and debris will appear between the two photoelectric comparison sensors, causing misjudgment. Utility Model Content
