Description

Technical Field

[0001] This invention relates to the field of textile production material supply technology, specifically a yarn bobbin turning and pushing device. Background Technology

[0002] In automated industries, the supply of textile raw materials is a crucial factor affecting weaving efficiency. Currently, the handling of the movement of yarn bobbins still relies on manual labor or robotic arms. Manual methods are inefficient and have many uncontrollable factors, failing to meet the industry's requirements for manufacturing efficiency. While robotic operations are highly efficient and offer stable control, they require higher costs and more specialized operators.

[0003] According to the Chinese patent publication number CN114572770A, an automatic yarn bobbin feeding device is disclosed. The automatic yarn bobbin feeding device in this invention patent is a feeding box and a storage box that are connected and connected to each other. The storage box is used to stack yarn bobbins, and the yarn bobbins automatically enter the feeding box from the through opening. The feeding box is fed in an orderly manner by a chain belt and a yarn bobbin conveying plate structure.

[0004] However, the storage bin of the automatic yarn bobbin feeding device discharges material by gravity. Since the yarn bobbin has a tubular structure, when stacked, the forces on its cylindrical surface reach a state of equilibrium, forming a stable stacked structure. This means that the yarn bobbin will become clogged inside the storage bin, causing it to block the through opening and preventing it from entering the feeding bin normally, thus affecting the normal feeding process. Therefore, the feeding structure of the automatic yarn bobbin feeding device needs further improvement. Hence, a yarn bobbin flipping and pushing device is proposed. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a yarn bobbin turning and pushing device, which has the following beneficial effects:

[0020] 1. This yarn bobbin turning and pushing device works by fitting the yarn bobbin body to be fed onto the sleeve cylinder. Then, the feeding process system controls the screw motor to drive the threaded screw, causing the lifting block to rise and pull the connecting block through the linkage rod, which drives the turning box to rotate 90° around the bearing seat as the axis. Then, the cylinder seat pushes the limit seat through the piston push rod, controlling the pusher plate to advance towards the outside of the turning box.

[0021] 2. The yarn bobbin turning and pushing device drives the receiving shaft roller through a geared motor. The receiving trough frame turns the yarn bobbin body over and discharges it into the conveyor belt for feeding. Symmetrically distributed through-beam photoelectric switches are set up. If the yarn bobbin body is stacked vertically, it will block the laser path of the two through-beam photoelectric switches. At this time, the feeding process system will control two electric push rods to start, push the two yarn bobbin bodies down, and achieve the effect of orderly and neatly placing the yarn bobbin bodies into the conveyor belt.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-6 A yarn bobbin flipping and pushing device includes a workbench 1, a support frame 2 fixedly connected to the top left side of the workbench 1, a flipping and pushing structure 3 provided on the left side of the support frame 2, and a guiding and feeding structure 4 provided on the top of the workbench 1.

[0031] The flipping and pushing structure 3 includes a flipping box 301 movably installed on the left side of the support frame 2. A connecting block 302 is fixedly connected to the front side of the flipping box 301. A connecting rod 303 is rotatably connected to the front side of the connecting block 302. A guide rod 304 is fixedly connected to the front side of the flipping box 301. A damping spring 305 is sleeved on the outside of the guide rod 304. A limit seat 306 is sleeved on the outside of the guide rod 304. A pushing plate 307 is provided inside the flipping box 301.

[0032] The guiding feeding structure 4 includes a receiving shaft roller 401 rotatably connected to the inner side of the support frame 2. A receiving groove frame 402 is fixedly sleeved on the outside of the receiving shaft roller 401. A through-beam photoelectric switch 403 is fixedly installed on the top inner side of the receiving groove frame 402. An electric push rod 404 is fixedly installed inside the receiving groove frame 402.

[0033] Furthermore, a bearing seat 5 is fixedly installed on the left side of the support frame 2. The top front and top rear sides of the tilting box 301 are rotatably connected to the inner side of the bearing seat 5. A steering angle sensor 6 is fixedly installed at the front end of the bearing seat 5. A drive shaft structure is rotatably connected to the rear side of the steering angle sensor 6. The drive shaft is fixedly connected to the top front side of the tilting box 301.

[0034] Specifically, the tilting box 301 tilts around the bearing seat 5 as the axis, and connects the drive shaft structure of the steering angle sensor 6 to the top front side of the tilting box 301. When the tilting box 301 tilts, it will drive the drive shaft to rotate synchronously.

[0035] The steering angle sensor 6 is internally composed of an optical coupling element and a perforated slot plate. The drive shaft is fixedly connected to the perforated slot plate. The optical coupling element is composed of a light-emitting diode and a photosensitive crystal triode. The perforated slot plate is located in the middle of the light-emitting diode and the photosensitive crystal triode. When the drive shaft drives the perforated slot plate to rotate, several light-transmitting circular holes on the perforated slot plate will allow the light emitted by the light-emitting diode to enter the photosensitive crystal triode. At this time, the photosensitive crystal triode detects different light signals and generates corresponding data differential signals according to the changes in the light passing through the circular holes on the perforated slot plate. The detected data differential signals are transmitted to the feeding process system to calculate the rotation angle and rotation direction of the perforated slot plate, that is, to obtain the rotation angle and rotation direction of the tilting box 301 and other data.

[0036] Furthermore, a drive assembly 7 is provided on the left side of the worktable 1. The drive assembly 7 includes a lead screw motor 701 fixed on the left side of the worktable 1. A threaded lead screw 702 is fixedly connected to the output end of the lead screw motor 701. A lifting block 703 is connected to the external thread of the threaded lead screw 702. The connecting rod 303 is rotatably connected to the back of the lifting block 703 at the end opposite to the connecting block 302.

[0037] Specifically, the lead screw motor 701 drives the threaded lead screw 702, which in turn drives the lifting block 703 to move up and down. At this time, the lifting block 703 pulls the connecting block 302 through the connecting rod 303, and the connecting block 302 drives the tilting box 301 to tilt around the bearing seat 5 as the axis.

[0038] Furthermore, an L-shaped frame 8 is fixedly attached to the outer sleeve of the threaded screw 702, and an eddy current proximity switch 9 is fixedly installed on the inner side of the L-shaped frame 8. A metal ring 10 is fixed to the front of the lifting block 703, and the eddy current proximity switch 9 has its sensing end on the side facing the metal ring 10.

[0039] Specifically, when the lifting block 703 approaches the top of the threaded screw 702, the metal ring 10 enters the sensing area of ​​the eddy current proximity switch 9. The eddy current proximity switch 9 is composed of an LC high-frequency oscillator and an amplification processing circuit. When the metal ring 10 approaches the oscillating sensing head that generates an electromagnetic field, eddy currents are generated inside the metal ring 10. These eddy currents react on the proximity switch, thereby attenuating the oscillation capability of the eddy current proximity switch 9 and causing changes in the parameters of the internal circuit. The feeding process system detects these parameter data to determine whether the metal ring 10 is close enough, and then controls the opening and closing of the screw motor 701 to limit the upward movement of the lifting block 703.

[0040] Furthermore, a cylinder seat 11 is fixedly installed on the left side of the tilting box 301, and a piston push rod is movably connected to the left side of the cylinder seat 11. The left end of the piston push rod is fixedly connected to the top of the limiting seat 306. Four slide rods 12 are fixed inside the tilting box 301. The right end of the limiting seat 306 extends into the interior of the tilting box 301 and is fixedly connected to the push plate 307. The push plate 307 is slidably connected to the outside of the four slide rods 12.

[0041] Specifically, the feeding process system controls the cylinder seat 11, which pushes the piston rod, causing the limit seat 306 to move to the left side of the guide rod 304. At this time, the damping spring 305 will rebound, and the limit seat 306 will pull the push plate 307 to slide along the slide rod 12.

[0042] Furthermore, two sleeve cylinders 13 are fixedly connected to the inner right wall of the flip box 301. A yarn cylinder body 14 is sleeved on the outside of each of the two sleeve cylinders 13. Both yarn cylinder bodies 14 are located inside the pusher plate 307. The inner right wall of the pusher plate 307 has two circular grooves that are adapted to the sleeve cylinders 13.

[0043] Specifically, the pusher plate 307 drives the yarn cylinder 14 to move to the side that is detached from the sleeve cylinder 13, thereby achieving the effect of discharging material from the yarn cylinder 14.

[0044] Furthermore, the top of the support frame 2 is fixedly connected to a guide rail plate 15 with a ramp structure. Two sliding grooves are opened on the inner side of the guide rail plate 15. A material discharge groove is opened on the top of the support frame 2. The material discharge groove is connected to the bottom of the two sliding grooves and is located directly above the receiving shaft roller 401. A conveyor belt 16 is connected to the inner side of the worktable 1.

[0045] Specifically, after the yarn bobbin 14 is unloaded, it enters the feeding trough through the guide rail plate 15 and then falls into the receiving trough frame 402.

[0046] Furthermore, a geared motor 17 is fixedly installed on the front of the support frame 2. The output end of the geared motor 17 is fixedly connected to the front end of the receiving shaft roller 401. There are two through-beam photoelectric switches 403 and two electric push rods 404, which are located on the inner front wall and inner rear wall of the receiving groove frame 402, respectively. A laser emitting end and a receiving port are provided on the opposite side of the two through-beam photoelectric switches 403. There are two partitions on the inner side of the receiving groove frame 402.

[0047] Specifically, since the installation height of the two through-beam photoelectric switches 403 is less than the height of the yarn bobbin 14 and greater than the diameter of the yarn bobbin 14, when the yarn bobbin 14 is vertically lowered and stacked, the vertical state will block the laser path of the two through-beam photoelectric switches 403. The receiving ports of the two through-beam photoelectric switches 403 are both avalanche photodiode structures. By detecting changes in photoelectric signals, they transmit signal data to the feeding process system. The feeding process system controls two electric push rods 404 to push the two yarn bobbins 14 down and place them neatly and orderly on the conveyor belt 16 for feeding.

[0048] In summary, the working principle of the yarn bobbin turning and pushing device is as follows: First, the yarn bobbin body 14 is sleeved on the sleeve cylinder 13 by the mechanical arm structure. Then, the feeding process system controls the screw motor 701 to drive the threaded screw 702, controls the lifting block 703 to rise, and pulls the connecting block 302 through the connecting rod 303, so that the moving turning box 301 rotates 90° around the bearing seat 5 as the axis. At this time, the rotation angle sensor 6 detects the rotation angle and rotation direction data of the turning box 301.

[0049] Then, the feeding process system controls the cylinder seat 11 to push the limit seat 306 through the piston push rod, and controls the pusher plate 307 to move outward towards the outside of the flip box 301. At this time, the yarn bobbin 14 is pushed away from the sleeve cylinder 13 and falls into the receiving groove frame 402 below through the two sliding grooves of the guide rail plate 15. The reduction motor 17 drives the receiving shaft roller 401 to drive the receiving groove frame 402 to flip, and discharge the yarn bobbin 14 into the conveyor belt 16 for automatic feeding.

[0050] Symmetrically distributed through-beam photoelectric switches 403 are installed inside the receiving trough frame 402. The installation height of the through-beam photoelectric switches 403 is less than the height of the yarn bobbin 14, but greater than the diameter of the yarn bobbin 14. If the yarn bobbin 14 is stacked vertically, it will block the laser path of the two through-beam photoelectric switches 403. At this time, the feeding process system will control the two electric push rods 404 to start, push the two yarn bobbin 14 to fall down, and then place the yarn bobbin 14 into the conveyor belt 16 in an orderly manner.
