Self-propelled trolley addressing device

Abstract

The invention discloses a self-propelled trolley addressing device. The self-propelled trolley addressing device comprises a photoelectric sensor support, a coding plate, a self-propelled trolley, a rail, a coding plate support, a programmable logic controller PLC (programmable logic controller) and two photoelectric sensors, the photoelectric sensor support is arranged on the right side of the self-propelled trolley, two photoelectric sensors are respectively arranged at the upper part and the lower part of the photoelectric sensor support, the coding plate support is arranged on an auxiliary beam, the coding plate is arranged on the coding plate support, two horizontal waist-shaped holes are formed in the coding plate, two rows of longitudinal waist-shaped holes are formed in the coding plate corresponding to two photoelectric sensors, and the photoelectric sensor is a through-beam photoelectric sensor. According to the self-propelled trolley addressing device, the number of trolley conductor is few, the trolley conductor has no segmentation, the communication is fast, the locating and addressing operations are accurate, and the cost is low.

Description

technical field [0001] The invention relates to the application technology of a photoelectric sensor, in particular to a self-propelled trolley address recognition device used on a self-propelled trolley conveying line. Background technique [0002] The self-propelled trolleys on the existing self-propelled trolley conveyor line use the sliding contact line to realize positioning and addressing. The electrical signal of the trolley is transmitted to the programmable logic controller PLC to determine the exact position of the trolley. However, in some application environments where the process action is relatively complicated (such as the assembly workshop of the automobile factory, the welding workshop, etc.), too many parameters need to be set. The number of trolley lines and over-dense trolley line segments require a particularly large workload and are extremely difficult. Therefore, this addressing method cannot adapt to the positioning and addressing of self-propelled tr...

[0002] The self-propelled trolleys on the existing self-propelled trolley conveyor line use the sliding contact line to realize positioning and addressing. The electrical signal of the trolley is transmitted to the programmable logic controller PLC to determine the exact position of the trolley. However, in some application environments where the process action is relatively complicated (such as the assembly workshop of the automobile factory, the welding workshop, etc.), too many parameters need to be set. The number of trolley lines and the over-dense trolley line segments require a particularly heavy workload and are extremely difficult. Therefore, this addressing method cannot adapt to the positioning and addressing of self-propelled trolleys in an application environment with complex technological movements.
