Description:A Patrolling & Positioning Device for Automatic Piecing Units
Field of Technology
The present invention relates to the field of textile equipment, in particular to a patrolling & positioning device for automatic piecing units.
Background Technology
In spinning mills, the ring spinning machine is a commonly used device, and yarn breakage often occurs during the operation of the ring spinning machine. There are usually more than 1,600 spindles on the device. To detect yarn breakage timely, a plurality of workers are required to continuously monitor the ring spinning machine on both sides along the entire frame. When yarn breakage occurs, broken yarns must be manually pieced and the spinning process must also be restarted immediately after treatment to avoid wasting yarns. At present, broken yarns must be manually pieced and the spinning process must be restarted. Patrolling a yarn breakage position in a traditional manner, may result in delayed patrolling, leading to yarn waste. At the same time, a large amount of manual labor imperceptibly increases the costs of a mill. In response to this problem, automatic piecing units are also available on the market.
However, such machines are currently all travel on the ground. The ground surface may be uneven, which can lead to inaccurate positioning of the automatic piecing unit upstream the spinning machine requiring the piecing operation. At the same time, due to the inaccurate positioning of the piecing machine, the piecing operation may end in failure, lead to more attempts to piece broken yarns together, and ultimately result= in a large amount of yarn waste and power consumption. To prevent misalignment of the automatic piecing unit due to the uneven ground surface, the automatic piecing unit must be equipped with various additional units including sensing elements, control devices and levellers, such as electronic mechanical actuators used to control and guide the automatic piecing unit to stick tightly to uneven ground. The additional elements result in high production costs of the automatic piecing unit.
Therefore, the purpose of the present patent is to design a simple and reliable device that helps automatic piecing machines perform piecing quickly and stably.
