Description

Technical Field

[0001] The invention relates to an automatic pagoda tube marking machine, in particular to a pagoda tube positioning and ejecting feeding structure of a pagoda tube automatic marking machine, and belongs to the technical field of non-standard machinery for post-spinning process of cotton spinning. Background Art

[0002] The textile process of a spinning mill includes two parts: spinning process and weaving process. Among them, spinning generally has three major processes: pre-spinning, spinning, and post-spinning. The post-spinning process is divided into winding, doubling, and twisting. The main process for completing single yarn is: winding. Most of the yarns after doubling and twisting also need to go through the winding process. Winding is to wind the yarn on the pagoda tube through the winder. The purpose of winding is to change the winding of the yarn and increase the yarn capacity of the yarn package. The shape and structure of the bobbin of the wound yarn ensure the smooth unwinding of the subsequent process and improve the productivity of the subsequent process. At present, most of the basic bobbins used for winding are pagoda tubes. The pagoda tube is a conical structure with a large end and a small end. Its material is generally mostly paper. Some manufacturers also use plastic materials to make pagoda tubes for repeated use. As people now pursue diversified clothing, the varieties and counts of yarns are increasing, and the varieties of yarn bobbins after winding are also increasing. It is necessary to mark these different yarn bobbins separately to avoid confusion in the subsequent warping, weaving and other processes. Since the confusion of bobbins will cause serious problems on the surface of the cloth after weaving, which will cause the whole cloth to be downgraded or even scrapped, the marking work is very important. For new spinning methods, such as air spinning, vortex spinning, and air jet spinning, the spinning process is simplified. Cotton strips can be directly spun into yarns at high speed and wound on pagoda tubes. Because there are multiple spinning varieties, they also need to be marked. For some spinning mills that spin yarns of a single variety and count, the variety and count information of the yarn can be printed on the inside of the pagoda tube when manufacturing the pagoda tube, which can greatly reduce the marking cost. However, for cotton spinning manufacturers that spin small batches of multi-variety yarns all year round, almost all of them use the method of manually sticking label paper to each pagoda tube to mark the count and variety of the yarn. The location of the label paper is generally at the inner edge of the pagoda tube.

[0003] In order to facilitate the transportation of pagoda tubes, all manufacturers of pagoda tubes use string combinations, that is, the small end of the pagoda tube is inserted into the large end hole of another pagoda tube. Each string of pagoda tubes generally has 25-30 pieces, and then multiple strings are packed in cartons or woven bags and transported to cotton spinning manufacturers. Due to the extrusion during transportation, it becomes very difficult to separate a single pagoda tube and label it inside. At this time, workers have to repeatedly swing the pagoda tube on the ground to loosen it before separating and labeling it. The pagoda paper tubes with manual labels must be reassembled and transported to the winding machine for use. The workload is huge and boring.

[0004] Manually pasting labels inside the conical tubes has a fatal flaw, which is label detachment. Even if the detachment rate is as low as one in a thousand, it can sometimes lead to unbearable consequences. Since it is small-batch spinning, the cost of re-spinning is too high, and mixing is even more impossible. We have no choice but to discard the cone yarn, resulting in waste. There are many reasons for label detachment. Sometimes, the label is not pasted properly; sometimes, there are too many scraps of paper inside the conical paper tube, making the pasted label insecure; sometimes, it detaches during the subsequent process transfer; and sometimes, it also detaches during use.

[0005] Therefore, cotton mills, especially those that spin small batches and a variety of products throughout the year, need a method of marking, such as using laser, inkjet, or stamping, to mark information such as the yarn count, variety, production date, shift, personnel, manufacturer name, and logo inside the conical paper tubes. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a positioning and pop-up feeding structure for a string of conical tubes in view of the above-mentioned prior art.

The positioning baffle can position the conical tubes of the separation mechanism in the previous process, and the pop-up hook pops the marked conical tubes out of the trough to the next process, achieving two functions through one mechanism.
