Description

TECHNICAL FIELD

[0001] The utility model belongs to textile instrument technical field relates to a movable creel for automatic hosiery machine. BACKGROUND

[0002] In the polyester filament field, the production of DTY bobbins is a continuous and precise process. Starting from the uninterrupted production of DTY bobbins by the elasticizer, it goes through strict finished product inspection, including regular physical property sampling inspection, usually including two aspects of appearance and dyeing index full inspection, to accurately define the grade of each bobbin. The key is the dyeing inspection link. In this stage, the hosiery worker uses the hosiery machine to test each DTY bobbin into a 5 to 10 cm long sock belt, and then determines the dyeing grade of each bobbin through a series of standardized dyeing and color judgment processes, so as to judge whether the grade of the DTY bobbin is abnormal, and then the specific bobbin with abnormal grade is pulled out from the creel for subsequent grading and packaging treatment. Therefore, the quality and efficiency of the sock belt are very important to the whole quality inspection process.

[0003] The traditional hosiery machine used at present is supplied with yarn by the hosiery machine yarn accumulator at intervals, and the yarn is knotted by manual single spool, which is numbered in sequence with the normal DTY creel (such as Figure 1 ), showing a continuous S-shaped sequence (the numerical sequence in Figure 1 ) of sock belt test samples, and the sock belt is written and then judged by the color judgment section. However, because each bobbin of the traditional hosiery machine must be shaken and knotted, the sock belt worker has a high labor intensity and low efficiency.

[0004] The automatic hosiery machine can realize automatic shaking with one knot, but it cannot be directly connected with the DTY creel, and the yarn bobbins on the DTY creel need to be transferred to the creel for arrangement and transition, and then connected with the automatic hosiery machine.

[0005] A creel suitable for automatic hosiery machine is disclosed in the patent with publication number CN211394839U, which comprises a creel body, the creel body comprises a chassis and first and second supports arranged side by side on both sides of the chassis, the first support comprises a first vertical rod arranged vertically on both ends of one side of the chassis and a plurality of first horizontal rods arranged between the first vertical rods, a plurality of guide rings are arranged on each first horizontal rod, the second support comprises a plurality of second vertical rods arranged vertically on the other side of the chassis, a plurality of bobbin rods for hanging bobbins are arranged on each second vertical rod, each guide ring is arranged correspondingly to the adjacent bobbin rod, one end of each bobbin rod is movably arranged on the corresponding second vertical rod, and the other end of each bobbin rod extends towards the first support. Before the socks are woven, the yarn heads and tails of the bobbins can be connected correspondingly at one time, the number of broken yarns is reduced, and the production efficiency is improved to a certain extent. However, the creel has the following shortcomings:

[0006] (1) Only for the production scene without the need of the sequence sock, it cannot adapt to the situation of the sock dyeing test, the dyeing index is the key core index of the elastic DTY bobbin finished product inspection, usually needs to weave a section of sock belt according to the spindle number sequence, then judges the dyeing performance of each bobbin through the dyeing and judging process, and further determines the grade, the above creel cannot adapt to the requirement of the sequence sock.

[0007] (2) The inconvenience of the position and the replacement of the silk bobbin: the silk bobbin needs to be sequentially transferred from the DTY silk car to the creel one by one, and after the trial weaving is completed, the silk bobbin also needs to be sequentially transferred back to the DTY silk car, for the scene needing to frequently replace the bobbin for quality inspection, the labor intensity is too high, and the working efficiency is low.

[0008] (3) The bottom of the creel is provided with universal wheels, when the sock weaving machine is frequently switched, it needs to be frequently and accurately positioned to ensure the accurate position of the bobbin and the sock machine, which is time-consuming, and if the position is not accurate, the quality of the sock belt cannot be guaranteed, the sock is often rewoven, and the dyeing quality and the production efficiency are greatly affected.
