Technical Field

The invention relates to a full-automatic creeling device of a drawing frame, belonging to the technical field of textile machinery.

Background

In the spinning process, the drawing process is the last key process with the merging function, and uneven evenness and uneven weight of the cotton sliver can be greatly improved. With the development of modern automatic control technology and the application of novel materials on a drawing frame, the drawing speed of the modern drawing frame is developed rapidly, and meanwhile, with the application of various capacity increasing technologies, the cotton sliver capacity is greatly improved. When the output can is full, the empty can needs to be replaced, the modern drawing frame adopts manual, semi-automatic and automatic ways to replace the can, and the drawing frame has the defects of small quantity of spare empty cans, long can replacing time, high labor intensity of a stop buffer worker and the like, and the development of the spinning industry in China is severely restricted.

In the case of a full can, the sliver can has a mass of more than 20 kg. The large-capacity sliver can greatly reduces the labor intensity of a car stop worker in the subsequent process, but is a great challenge for the car stop worker in the drawing process. The full bobbin quality is too large, if the drawing frame is not provided with an automatic bobbin changing device, after the drawing frame is full and the main machine stops, the manual replacement of the output bobbin is a high-intensity work task, and under the existing bobbin discharging speed, the frequency of bobbin replacement is high, and the labor intensity of a car stop worker is higher.

The automatic creeling device of the drawing frame not only needs to complete the replacement of an output sliver can, but also needs to cut off the sliver after the sliver can is full, and the broken end of the sliver falls into a supplementary working barrel, so that the sliver can be stored in a coil during the automatic circulating operation of the drawing frame. If the drawing frame is not provided with automatic broken slivers, after the full barrel is pushed out, the cotton slivers need to be manually broken, and then the drawing frame is operated to continue running. The drawing frame can not realize automatic circulation operation, and the automatic bobbin changing is semi-automatic bobbin changing. The longer the time for the host to stop waiting for the bar breaking of the car stop worker is, the lower the working efficiency of the drawing frame is, and in order to reduce the host stop waiting time, the number of car stations of each car stop worker is limited; and the drawing frame needs to frequently move between drawing frames, thereby increasing the labor intensity of a car stop worker.

As early as the middle of the 60's of the 20 th century, China adopted quarter disc rotary type creeling devices on the type A272-A of the domestic second-generation drawing frame. The standby cylinder and the full cylinder are respectively borne by the two large circular discs which do rotary motion. A cross-shaped rotary shifting fork disc is arranged between the two large circular discs to assist in moving the sliver can. The device is applied to a double-eye drawing frame, a main machine stops when a barrel is full, a shifting fork disk rotates 180 degrees to sequentially push two full barrels to a large disc on the left side, and two standby barrels are sent to a coiling station from the large disc on the right side. The cotton sliver replacing device has the advantages of small occupied area, convenient operation, and no need of arranging a cotton sliver cutting device because the full barrel has a large moving stroke and the cotton sliver is easy to break. However, the mechanical structure of the device has some defects, and the device is easy to fail when the cylinder is replaced, so the device is not widely used.

The development of the automatic creeling device of the foreign drawing frame is rapid, the electrified control is adopted, the automatic control of the creeling action is realized through a plurality of servo motors and travel switches, the creeling action is accurate, and the creeling fault rate is low. The German Qingze 720-type drawing frame adopts a CAN-O-MAT type creeling device. When the working barrel is full, the barrel pushing device pushes the full barrel to the barrel supplementing station, then the barrel replacing device resets, the rotating arm arranged at the top end of the barrel pushing device overturns, the barrel pushing device is started again to push the full barrel out of the drawing machine, the barrel supplementing device pushes the spare barrel to the barrel supplementing station, and the spare barrel is pulled to the coiling station through the rotating arm at the top end of the barrel pushing device when the barrel pushing device resets. The device has stable and reliable tube replacement, but the tube replacement action is complex, so the time for completing the tube replacement is long.

With the development of automatic control technology, the automatic creeling device of the drawing frame is gradually developed into automatic program control from adopting complex mechanical control, and the positioning of the device by a travel switch is developed into the positioning of an optical sensor, so that the action control of the creeling device is more accurate.
