A control method of the brake when the tape machine stops

Abstract

The invention discloses a method for controlling a band-type brake in stopping of a sealing-tape machine. The method mainly comprises the steps of setting and controlling a fixed low-speed stopping curve, estimating zero returning time based on the obtained fixed low-speed stopping curve, sending out a band-type brake command based on the estimated zero returning time, and adjusting the estimated zero returning time according to the execution process and actual operation states. The method for controlling the band-type brake in stopping of the sealing-tape machine can overcome the defects that in the prior art, band-type brake action time is uncertain, mechanical equipment is easily damaged, and the service life of the sealing-tape machine is affected, and has the advantages that band-type brake action time is certain, mechanical equipment can not be easily damaged, and the service life of the sealing-tape machine is not affected.

Description

technical field [0001] The invention relates to the electrical automation control part in the field of modern transportation, in particular to a control method for a brake when a belt conveyor stops. Background technique [0002] In the application of tape machines in the industrial field, many tape machines use electromagnetic or hydraulic mechanical brakes with switching values ​​to mechanically lock the tape machine when it stops. For inspection and troubleshooting. [0003] In the past parking brake mode, when the parking command is issued, the brake command is issued according to a fixed time, and the brake mechanism performs the brake action. In most cases, the tape machine runs at a fixed speed. As long as the time is set properly, the brake can be activated at the same time when the speed of the tape machine is zero to avoid mechanical shock. However, in the start-up stage of the belt conveyor or a certain set speed operation stage required by production, the brake...

AI Technical Summary

Problems solved by technology

The advanced situation means that the brake has been put into action before the speed of the tape machine stops to zero, which will cause strong mechanical vibration and damage the mechanical equipment; the lagging situation means that the brake starts to act after the tape machine has stopped for a period of time There is no mechanical vibration and shock, but in some production occasions, due to the gravity of the overall potential load, the belt machine will run in the opposite direction, and a small "slip" will occur. Putting the brakes in the opposite direction will also cause a certain degree of damage. mechanical shock

In this way, it will affect the service life of the tape machine

[0004] In the process of realizing the present invention, the inventor found that there are at least some defects in the prior art, such as uncertain brake action time, easily damaged mechanical equipment, and affecting the service life of the tape machine.
