Lifting control device of gripping arm of reciprocating cotton-grapping machine and control method

Abstract

The invention provides a lift control device of a grappler arm of a reciprocating bale plucker and a control method thereof. The lift control device comprises a tower pedestal, a tower body, a grappler arm, a bothrium, a guide rail, a drive motor of the tower pedestal, a lift motor of the grappler arm and a control system. The lift control device is characterized in that the lift motor is equipped with an inverter or an integrated frequency machine; a sensor used for detecting the lifting position of the grappler arm is installed on the output shaft of the lift motor; the sensor is connected with the computer of the control system and the output unit of the computer is connected with athe frequency controller of the lift motor. The sensor transmits detecting data to the control system of the computer. And an instruction is output to the frequency controller of the lift motor by the computer to control the action of the lift motor. When the lift motor stops or starts, the frequency gradation principle of the frequency is used to set the approximate time of raising or reducing the speed of the grappler arm so as to avoid rigid shock on a main body and a reduction gearbox caused by raising or reducing the speed of the grappler arm. The positioning accuracy in lifting or lowering the grappler arm is improved. In addition, the speed in lifting or lowering the grappler arm is adjustable and three or more kinds of lifting speed can be achieved.

AI Technical Summary

Benefits of technology

This technology improves upon existing systems by allowing devices to transmit data faster without being affected too much from other parts that they were designed around them. It achieves this through controllers called frequency converters that gradually change their output frequencies based on different processes needed at startup time. Additionally, there may exist multiple types of motors used together - one type slow down while another slower version accelerates upward. By utilizing these techniques, the system becomes smoother and efficient overall.

Problems solved by technology

This patented technology describes an improved apparatus used for efficiently producing specialized fibre products called rovings (roving). These materials require specific conditions like temperature, humidity, pressure, and other factors to work properly with them. However, current methods involve complicated mechanical systems which can lead to instability issues when trying to lift heavy loads quickly without damaging their components. Therefore there needs a better solution to ensure accurate location and stable operation of this type of material production tool.
