Background
At present, all tray type automatic bobbin winders are required to be equipped with automatic bobbin dropping devices. The automatic doffing device needs to be switched among a plurality of positions during working, needs to be accurately positioned on a spindle position needing to work and needs to clearly determine the information of the current spindle position. The positioning technology adopted by the existing automatic doffing device comprises the following steps:
1. the single ingot with the requirement on the doffing actively sends the infrared photoelectric code through the photoelectric emitting device, and after the doffing device reaches the single ingot, the information sent by the single ingot is read through the photoelectric receiving device, and the information is analyzed to carry out positioning. The main problems with this positioning approach are: 1) only the single ingot needing doffing can send information, so that the doffing device cannot be positioned at the single ingot without doffing requirements; 2) because the textile equipment is in an environment with more dust and flying, light is used as a transmission medium, and the situation that the signal transmission fails due to the fact that the light is blocked can occur; 3) this approach requires the mounting of a photoemissive device on each single ingot, resulting in a relatively high cost.
2. When the automatic doffing device is positioned, the automatic doffing device actively sends a demand signal; and when the single ingot receives the demand signal, the ingot position information is transmitted to the automatic doffing device in a communication mode. This positioning approach solves the problem of arbitrary single-ingot positioning in the first approach. The drawbacks of items 2) and 3) in the first mode still remain. In terms of cost, each spindle does not need to be provided with a photoelectric emitting device, but needs to be provided with a photoelectric receiving device, so that the cost is high. Meanwhile, the positioning mode requires information transmission through a communication mode, so that the communication aspect has higher requirements.
3. And (4) a bar code positioning mode. When the automatic doffing device is positioned, a bar code reading device mounted on the automatic doffing device reads information on a bar code mounted on a single spindle, and positioning is performed by analyzing the information. This positioning method can also accomplish any single ingot positioning. But still has the problems of light blockage by the fly and high cost. The cost of the bar code reading device is also relatively high.
