Problems solved by technology

If the accident is serious, it will directly cause damage to structural components such as the motor, tray, and mandrel base.
This situation occurs because the transmission system of the double mandrel equipment fails, and the motor cannot be adjusted to decelerate and stop normally. Manual intervention is frequently required, which affects the normal production and it is difficult to truly realize unmanned management.

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] A control method for preventing heavy-load failure of a double-mandrel drive motor, involving equipment including a doffing bin door in a wire automatic collection system in a high-speed wire production line, double-mandrel equipment, a coil transport trolley, a detector, and the like. The double-mandrel equipment here mainly includes a tray and a double-mandrel (hereinafter referred to as mandrel A and mandrel B), which are respectively driven by a motor, and the motor is controlled by the transmission system of the double-mandrel equipment. The structural difference between the double mandrel equipment and the prior art is mainly that a weighing device is added on the tray. The specific steps of the control method in this embodiment are as follows, which are executed by the control system. The control system is used to intera...

Abstract

The invention discloses a control method for preventing a heavy-load fault of a double-core-rod transmission motor. The control method comprises the following steps that when a wire coil is heavier, namely exceeds a set value, a control system gives an advanced deceleration time delta T, and then a transmission system is controlled to decelerate the motor in advance delta T on the basis of the starting point of the current deceleration time. When the wire coil is heavier, the control system gives the advanced deceleration time according to the weight of the wire coil, and then the transmission system is controlled to decelerate the motor in advance, so that the peak impact of heavy weight on the motor and the transmission system thereof can be avoided, the heavy-load fault is prevented, the production efficiency and the normal production are better guaranteed, and the realization of unmanned management is facilitated.

Description

technical field [0001] The invention belongs to the technical field of wire rod collection for metal products, and in particular relates to a control method for preventing heavy-load faults of a double mandrel drive motor used for wire rod collection. Background technique [0002] In order to improve the competitiveness of enterprises, modern iron and steel enterprises are trying their best to upgrade and transform, and take the development path of intelligent manufacturing and machines replacing labor. The collection system of the double mandrel + PF (abbreviation of POWER&FREE CONVEYOR) line of the high-line production line can replace manual to realize fully automatic intelligent collection. The collection process is briefly described as follows: [0003] 1) The wire laying machine spins silk, and the spouted wire coil lies on the track above, and the wire coil is transported to the next process through the roller table; [0004] 2) After the detector detects the wire c...
