A method for tracking yarn roll materials

Abstract

The invention discloses a yarn roll material tracking method. When a hook, carrying a yarn roll, on a suspension chain conveying line moves to the position above a suspension chain material taking device and passes through an opposite-type photoelectric sensor, the opposite type photoelectric sensor receives a blocking signal and transmits the blocking signal to a controller, the position is the original point A of the yarn roll position at the moment, A=0, the horizontal position of the suspension chain material taking device is the same as the horizontal position of the opposite type photoelectric sensor, and the horizontal coordinate is A; the controller controls a servo encoder to work after receiving the signal, the position distance, from the position of the opposite type photoelectric sensor to the stop position, of the yarn roll is measured to be L, and therefore the horizontal position B of the end point of the yarn roll is measured to be equal to the sum of A and L; the controller controls a second servo electric cylinder to drive the suspension chain material taking device to operate by the distance L, and tracking material taking of the yarn roll is achieved; and because the suspension chain discharge position is not fixed, according to the method, the position of the photoelectric sensor is set to be the 0 point, tracking is conducted through the distance by which the suspension chain conveying line continues to operate, and therefore the final material taking position of the yarn roll is determined.

Description

technical field [0001] The invention relates to a tracking method, in particular to a yarn roll material tracking method. Background technique [0002] On the yarn roll production line, after the yarn roll production is completed, each machine will place the yarn roll on the hook of the suspension chain conveyor line, and the suspension chain conveyor line will transport the yarn roll to the retrieving device for material retrieving operation. Due to the random placement of the machines, it is necessary to control the empty hook of the suspension chain conveyor line to stop in front of each machine when loading materials, and when a position of the suspension chain conveyor line is on the upper Material operation, the other position is during the unloading operation. Since the distance between the positions of each machine is not fixed, the unsteady loading position will lead to the unfixed unloading position. Therefore, during the unloading operation, it is necessary to man...

[0002] On the yarn roll production line, after the yarn roll production is completed, each machine will place the yarn roll on the hook of the suspension chain conveyor line, and the suspension chain conveyor line will transport the yarn roll to the retrieving device for material retrieving operation. Due to the random placement of the machines, it is necessary to control the empty hook of the suspension chain conveyor line to stop in front of each machine when loading materials, and when a position of the suspension chain conveyor line is on the upper Material operation, the other position is during the unloading operation. Since the distance between the positions of each machine is not fixed, the unsteady loading position will lead to the unfixed unloading position. Therefore, during the unloading operation, it is necessary to manually control the suspension chain reclaimer to stop at The reclaiming operation is carried out at the reclaiming point, which causes great trouble to the reclaiming operation
