Description

Technical Field

[0001] The utility model belongs to the technical field of pantyhose production, and particularly relates to a device for aligning the cuffs of pantyhose. Background Art

[0002] The crotch joining process of pantyhose is an important link in the production process. It is to sew various parts of the pantyhose, such as the waist, body, crotch, and leg tubes, into a left - and - right - symmetric single - tube sock, and then connect the two single - tube socks at the crotch position by sewing or bonding to form a complete pantyhose. When the existing pantyhose is joined at the crotch, two single - tube socks need to be symmetrically sleeved on the positioning device up and down, and then the cuffs of the pantyhose are aligned up and down and pushed to the designated position on the positioning device. The positioning device transports the two single - tube socks to the subsequent workstations for crotch cutting and sewing. If there are deviations in the cuff alignment and the cuff position, it will lead to the failure of the crotch sewing of the pantyhose, resulting in product scrapping. Most of the existing pantyhose cuff alignments are carried out manually by workers. The alignment accuracy depends on the visual judgment of the workers, and the alignment accuracy fluctuates greatly and is uncontrollable, resulting in a decline in product quality. In addition, the manual alignment method is inefficient, seriously slowing down the production rhythm of the equipment and being unfavorable to the improvement of production efficiency.

[0028] The working process of the present utility model: The lower clamping device 1 is fixedly installed on a circulating turntable (not shown in the figure), and the circulating turntable drives the lower clamping device 1 to perform circular motion, circulating through the driving platform device 5. When the equipment is working, the lower single-layer pantyhose 3 is slidably sleeved on the lower U-shaped slide rod 1031 from the right end, and the upper single-layer pantyhose 4 is slidably sleeved on the upper U-shaped slide rod 203 from the right end. The cuffs 301 of the lower single-layer pantyhose 3 and the upper single-layer pantyhose 4 are close to the left-end openings of the upper U-shaped slide rod 203 and the lower U-shaped slide rod 1031. The upper U-shaped slide rod 203 abuts against the lower U-shaped slide rod 1031 to position and clamp the single-layer pantyhose. When the lower clamping device 1 drives the lower single-layer pantyhose 3 and the upper single-layer pantyhose 4 close to the driving platform device 5, the air cylinder 508 is activated to drive the top plate 509 to rise vertically. The top plate 509 contacts the lower end of the sliding column 2021 and lifts the upper clamping device 2 upward. The upper U-shaped slide rod 203 translates upward by a certain distance. After the upper clamping positioning frame 201 contacts the buffer table 5061, it stops moving. The upper U-shaped slide rod 203 disengages from the lower U-shaped slide rod 1031, and the lower single-layer pantyhose 3 and the upper single-layer pantyhose 4 are released from fixation. At this time, the left-end opening of the lower single-layer pantyhose 3 corresponds to the lower positioning plate 6044, and the left-end opening of the upper single-layer pantyhose 4 corresponds to the upper positioning plate 6043. At the same time, the driving platform 502 is activated to drive the sliding square rod 503 to translate to the right. The lower positioning plate 6044 extends into the lower single-layer pantyhose 3, and the upper positioning plate 6043 extends into the upper single-layer pantyhose 4. The middle partition plate 6042 is located between the lower single-layer pantyhose 3 and the upper single-layer pantyhose 4. The left-end cuff 301 of the single-layer pantyhose contacts the alignment fixing table 6041, and the alignment fixing table 6041 pushes the cuff 301 to move to the right; Since the cuffs 301 of the lower single-layer pantyhose 3 and the upper single-layer pantyhose 4 are not aligned vertically, when the cuff 301 of the lower single-layer pantyhose 3 contacts the alignment fixing table 6041, the cuff 301 just blocks the signal transmission between the sensor 6042-1 and the lower receiver 6044-1. The lifting device 604 drives the lower pressing table 6061 to rise through the lower lifting block 6042. The lower pressing plate 6064 contacts the cuff 301 of the lower single-layer pantyhose 3 to cooperate with the lower positioning plate 6044 to fix the cuff 301 of the lower single-layer pantyhose 3;When the mouth 301 of the upper single-tube hosiery 4 contacts the alignment and fixing table 6041, the mouth 301 exactly blocks the signal transmission between the sensor 6042-1 and the upper receiver 6043-1. The lifting device 504 drives the upper pressing table 6051 to descend through the upper lifting block 5041. The upper pressing plate 6054 contacts the mouth 301 of the upper single-tube hosiery 4, and cooperates with the upper positioning plate 6043 to fix the mouth 301 of the upper single-tube hosiery 4. At this time, the vertical alignment of the mouth 301 is completed. The alignment and fixing table 6041 returns to the right. After pulling the mouth 301 to the specified position, the lower pressing table 6061 and the upper pressing table 6051 are reset, and the positioning and clamping of the mouths 301 of the lower single-tube hosiery 3 and the upper single-tube hosiery 4 are released. Repeat the above actions once to improve the alignment and positioning accuracy. After completion, the sliding square rod 503 is reset, the alignment device 6 is separated from the mouths 301 of the lower single-tube hosiery 3 and the upper single-tube hosiery 4, the cylinder 508 is reset, and the upper U-shaped slide rod 203 and the lower U-shaped slide rod 1031 are repositioned and clamped on the upper single-tube hosiery 4 and the lower single-tube hosiery 4 for the next step of processing.;
