Description

Technical Field

[0001] The utility model relates to the technical field of distinguishing the big and small ends of a yarn bobbin, and specifically discloses a yarn bobbin turning device. Background Art

[0002] The big and small ends of a yarn bobbin refer to that in the manufacturing process of the yarn bobbin, its upper end and lower end are designed with different diameters or sizes to facilitate fixation and use on textile machinery. The existence of the big and small ends enables the yarn bobbin to be more firmly fixed on a sewing machine or other textile equipment, preventing the yarn bobbin from slipping or deforming during operation. At the same time, the design of the big and small ends also helps the smooth transmission of the yarn and the replacement of the yarn bobbin.

[0003] Therefore, automatic yarn bobbin inserting machines in a yarn bobbin library are all provided with a yarn bobbin turning device to ensure that the big end of the yarn bobbin is placed at the bottom and the small end is at the top, facilitating the subsequent processes of the automatic yarn bobbin inserting machine. For example, the patent with the publication number CN212076005U discloses a funnel device. The turning table funnel welding part is hollow with openings at the upper and lower sides, and there are 2 lever cylinders on the back. A first funnel side plate cover and a funnel yarn left stopper are arranged on the left side of the turning table funnel welding part, and a big and small end sensing piece right is installed on the funnel yarn left stopper. A second funnel side plate cover and a funnel tuber pipe right adjusting block are arranged on the right side of the turning table funnel welding part, and a big and small end sensing piece left is installed on the funnel tuber pipe right adjusting block. Magnetic proximity switches are arranged on the first and second funnel side plate covers to sense the big and small end sensing piece right and left, and control the lever cylinders on the same side.

[0004] The above scheme has the following problems in actual use:

[0005] 1. The big and small end sensing piece naturally hangs down by its own gravity. When the device is externally touched, it is extremely easy to cause mis-touching of the proximity switch, affecting the yarn bobbin turning process and causing material blocking.

[0006] 2. When the yarn bobbin enters the channel below the big and small end sensing piece, there is a lack of precise guidance, and it is easy to mis-touch the big and small end sensing piece when loading the yarn bobbin;

[0007] 3. When the yarn bobbin is discharged from the funnel, there is a lack of a supporting mechanism, which is easy to cause the yarn bobbin to be skewed, resulting in the failure of the yarn bobbin turning and affecting the efficiency. Summary of the Utility Model

[0008] Aiming at the above deficiencies of the prior art, the utility model provides a yarn bobbin turning device to solve the problem that the big and small end sensing piece is prone to mis-touching and affects the yarn bobbin turning.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figures 1-4As shown in the figure, a bobbin turning device includes a funnel 1 with a regular trapezoidal cross-section. On both the left and right sides of the upper opening of the funnel 1, a first cylinder 2 is provided; the first cylinder 2 is arranged on the side wall of the funnel 1, and the piston rod of the first cylinder 2 penetrates through the side wall of the funnel 1. In the normal state, the piston rod of the first cylinder 2 is in the extended state; a feeding channel 9 is fixedly arranged at the upper opening of the funnel 1; the bottom surface of the feeding channel 9 is arranged in a V shape; one end of the bottom surface of the feeding channel 9 is connected to the rear side of the upper opening of the funnel 1; an opening 901 is provided at the lower end of the bottom surface of the feeding channel 9; a second cylinder 10 is arranged at the opening 901; a push plate 11 is fixedly arranged at the output end of the second cylinder 10; the axis direction of the piston rod of the second cylinder 10 is parallel to one side of the bottom surface of the feeding channel 9. It can push up the bobbin on the inner bottom surface of the feeding channel 9 and accurately push it under the baffle 4, reducing the accidental touch of the baffle 4 during bobbin feeding.

[0030] In the above setting, mounting boxes 8 are fixedly arranged on the left and right side walls of the feeding channel 9; the mounting boxes 8 are arranged at the connection between the feeding channel 9 and the funnel 1; a baffle 4 is hinged in the mounting box 8, and the baffle 4 is integrally in an L shape; the baffle 4 includes a flat plate 401; the lower part of the flat plate 401 is hinged in the mounting box 8; an arc plate 402 is fixedly arranged at the lower end of the flat plate 401; the arc plate 402 penetrates through the mounting box 8; the arc plate 402 is arranged at an interval from the bottom surface of the feeding channel 9. When the bobbin moves along the bottom surface of the feeding channel 9, the large-end of the bobbin can push the arc plate 402, thereby driving the flat plate 401 to rotate around its hinge point with the mounting box 8, and then moving away from the proximity switch 7, so that the piston rod of the first cylinder 2 on this side receives a signal and retracts, and the large-end of the bobbin first drops, completing the turning of the bobbin. The upper part of the flat plate 401 penetrates through the mounting box 8 and then a folded-edge plate 403 is fixedly arranged; one end of a spring 5 is fixed on the upper side wall of the upper part of the flat plate 401, and the other end is fixedly arranged on the support 6. Through the setting of the spring 5, the accidental touch of the baffle 4 can be reduced, ensuring the smooth turning of the bobbin and the production efficiency. The support 6 is arranged on the top surface of the feeding channel 9; a proximity switch 7 is arranged on the support 6; the proximity switch 7 is electrically connected to the first cylinder 2.

[0032] When in use, the bobbin is poured in from one side of the material guide channel 9, and the bobbin falls into the lower part of the bottom surface of the material guide channel 9, and then the cylinder 10 is actuated to push the bobbin to move along the bottom surface of the material guide channel 9 and move to below the arc plate 402. Under the premise that the distance between the arc plates 402 on the left and right sides and the bottom surface of the material guide channel 9 is the same, the large end of the bobbin can move the baffle plate 4 to rotate due to its larger outer diameter, driving the folding plate 403 away from the proximity switch 7, thereby driving the cylinder 1 2 on this side to retract the piston rod, and the large end of the bobbin falls first; at the same time, the small end of the bobbin Since the head end has a smaller outer diameter, it cannot move the arc plate 402 on the other side, so the cylinder 2 at the small end of the yarn tube does not move, and the small end of the yarn tube is blocked at the piston rod of the cylinder 2 on this side, and falls after the large end of the yarn tube, and the yarn tube falls between the two semicircular tubes 1202; then it falls onto the yarn tube conveying device, and then the two-way cylinder 1201 is activated to drive the two semicircular tubes 1202 away, and the yarn tube is moved out from between the two semicircular tubes 1202 driven by the yarn tube conveying device, and then the yarn tube is conveyed to the next process by the yarn tube conveying device.
