Method and device for sensing signals for starting and stopping control of conveyor

Abstract

The invention discloses a method and a device for sensing signals for starting and stopping control of a conveyor. The method comprises the following steps of arranging a rotary bracket which can be pushed by a to-be-conveyed object above the tail part of a conveying belt of the conveyor, arranging a sensing plate at the tail end of the rotary bracket, and arranging a signal sensing switch which is matched with the sensing plate above the rotary bracket; when the to-be-conveyed object is moved to the tail part of the conveying belt, pushing and lifting up the tail end of the rotary bracket, enabling the sensing plate to enter the sensing range of the signal sensing switch, and enabling the signal sensing switch to control the stopping of the conveyor; when the to-be-conveyed object leaves off the conveying belt, enabling the tail end of the rotary bracket to fall down under the action of self gravity, enabling the sensing plate to disengage from the sensing range of the signal sensing switch, and enabling the signal sensing switch to control the starting of the conveyor. The method has the advantages that the occurrence of false signals is avoided, and the reliability is higher; the implementation of the method is easy, the structure of the device is simpler, the implementation cost is lower, and the subsequent maintenance is convenient; the applicability is high, and the method is favorable for being popularized.

Description

technical field [0001] The invention relates to a signal sensing method and device for start-stop control of a conveyor, belonging to the technical field of transmission equipment. Background technique [0002] The conveyor is generally driven by a reducer. The start and stop of the reducer needs to be controlled by a control system, and the control system needs a signal sensing device for feedback. At present, the relatively direct signal sensing method or signal sensing device with a relatively simple structure is generally used to distinguish whether the conveyed object has actually arrived, and false signals often occur, which not only easily causes damage to the transmission equipment, but even leads to safety accidents; and The implementation cost of the signal sensing method or device capable of accurately judging whether the conveyed object has actually arrived is relatively high, and its applicability is poor.
