An operating method for preventing a multi-stage conveying device from running without load

Abstract

The invention relates to a system and method for preventing a multi-stage conveying device from running in a no-load mode. The system comprises a conveying device and a plurality of discharging mechanisms arranged above the conveying device, wherein the conveying device comprises a plurality of stages of conveying mechanisms; the discharging mechanisms are distributed on each stage of conveying mechanism; the discharging mechanisms are sequentially marked as the first discharging mechanism, the second discharging mechanism to the M discharging mechanism in the advancing direction of the conveying device; the conveying mechanisms receive cloth bundles conveyed out by the conveying mechanism on the previous stage through the corresponding X discharging mechanism, and the value of X is 2-M. A detection mechanism is arranged at an outlet of each discharging mechanism; the detection mechanisms can detect that the cloth bundles enter the conveying mechanisms from the discharging mechanisms; the conveying detection time set after discharging of the first discharging mechanism, the second discharging mechanism to the M discharging mechanism is sequentially decreased progressively, and the conveying detection time is the time from discharging of the cloth bundles from the discharging mechanisms to conveying of the cloth bundles out of the conveying mechanisms.

Description

technical field [0001] The invention relates to a system for preventing no-load running of a multi-stage conveying device, in particular to a system and a method for preventing a multi-stage conveying device from running without a load. Background technique [0002] During the production process, the cloth needs to be packaged in bundles. After being bundled, it needs to be transported through the conveyor belt. During the transportation process, the detection system is designed according to the production site conditions and control requirements to realize the detection and detection of cloth bundles entering and leaving the conveyor belts at all levels. Identify the loading state of the conveyor belt, and try to avoid the no-load operation of the conveyor belt, so as to achieve the service life of the conveyor belt and save power consumption. [0003] The traditional conveyor belt no-load running detection is monitored by counting down the counter. When the counter value i...

Problems solved by technology

[0003] The traditional conveyor belt no-load running detection is monitored by counting down the counter. When the counter value decreases to zero, it means that the conveyor belt is empty. However, there will be a situation that when the cloth bundle falls on the conveyor belt, sometimes The bundles of cloth appear side by side. At this time, they are transmitted at the same time. Using a single infrared switch cannot accurately determine the number of bundles passing through, and the accuracy of identification and detection is poor. When there is no cloth bundle on, the counter value is still not reduced to zero, causing the conveyor belt to run continuously, wasting electric energy, and greatly reducing the service life of the conveyor belt
