Abstract

The invention discloses an accurate counting and detecting method for belt transmission of packed objects. In the upper part of both side frames of a belt conveyor, two pairs of opposite photoelectric switches are installed according to a set distance and situated in the opposite positions, and the photoelectric switches are connected with a counting control unit. The counting and detecting method comprises the following steps: 1) in each counting operation, the two pairs of photoelectric switches simultaneously detecting the first three pieces of single objects passing through a detection area, determining the reference transmission time value T reference, and automatically storing in the counting control unit; 2) detecting the running time length T test of the conveyed object passing through the change of the level of one pair of the photoelectric switches; and 3) obtaining number of objects conveyed and counting cumulatively according to n = T test / T reference. The accurate counting and detecting method has the advantages that the number of bags of the conveyed objects can be effectively detected, undetected condition of the laterally placed objects and the stacked bags is avoided, and accurate counting is achieved.

Description

technical field

[0001] The invention relates to a method for accurately counting and detecting bagged objects conveyed by a belt. Background technique

[0002] Belt conveyors are widely used in modern production operations, especially in industries characterized by bag packaging such as chemical fertilizers, salt industry, feed, grain, cement, sugar, etc. Belt conveyors are the main components in their production and circulation. transmission device. In the operation of using a belt conveyor to transport fixed and regular-shaped objects, the counting and detection method used is simple and accurate. However, in the transmission of non-fixed-shaped bagged objects, the requirements for the counting and detection method are relatively high. Therefore , the counting detection method is particularly important to ensure the counting accuracy when the conveyor transports the bagged objects.

[0003] Usually, the transmission operation of some bagged objects is carried out outdoor...
