Description

Technical Field

[0001] The utility model belongs to the technical field of button feeding machines, and in particular relates to an automatic button feeding device. Background Art

[0002] With the continuous development of society, the clothing sewing industry has developed rapidly. In the clothing sewing industry, an automatic button feeding device is often used. The automatic button feeding device is a conveying device for automatically feeding buttons.

[0003] The following problems have been found in the currently used automatic button feeding device during long-term use:

[0004] First, it is difficult for the button feeding die of the existing button feeding device to be automatically aligned with the center position of the button. After frequently replacing the button and the die, uneven force will cause changes in the clearance and position of the mechanical combined linkage parts, resulting in difficulty for the die to be aligned with the center position of the button. Manual adjustment and maintenance are required later, and the adjustment process is cumbersome and requires fine adjustment by professionals, which is difficult for general workers to master.

[0005] Second, after each replacement of buttons of different sizes (conventional diameters of 6 to 28 mm in the market) on the existing button feeding device, when changing from a small button of 6 mm to a button of 30 mm, the manufacturing tolerance values of the longitudinal and transverse linkage structures of the limiting device on the conveying mechanism will be amplified, or the small gaps caused by uneven force will result in larger transmission limiting errors. The structural design has insufficient rigidity, resulting in inaccurate limiting and low feeding accuracy, and the adjustment is relatively cumbersome.

[0006] Third, since the button feeding machine and the button sewing machine need to cooperate with each other, the installation accuracy requirements are high. The structure of the mounting seat of the existing button feeding device is complex, and the existing design is prone to looseness under the high-frequency vibration generated during the operation of the machine, and the debugging is troublesome and inefficient.

[0060] Embodiment 2

[0061] As Figure 11 shown, on the basis of Embodiment 1, the bearing 418 is connected to the clamping block 418, and the inclined push block 411 is installed on the fixed block 417, so that the contact between the inclined push block 411 and the bearing 418 can also realize the limit and adjustment of the protruding length of the material buckle 9 on the stripping plate 301 according to the second template buckle 8.

[0062] Working process: Before working, first pull the connecting frame 311 upward through the sliding rod 309. Under the pulling of the sliding rod 309, the longitudinal slider 304 on the connecting frame 311 will move upward along the longitudinal rail 303. Since the fixed plate 308 is installed on the connecting block 302, the first spring 310 will be compressed when the connecting frame 311 moves upward. Then, the first template buckle 7 is placed on the first support table 405, and then the sliding rod 309 is released, so that the first spring 310 elongates to push the connecting frame 311 downward until the connecting frame 311 stops moving downward after the end of the adjusting bolt 406 on the adjusting block 422 contacts the first template buckle 7.

[0063] At this time, the distance between the air blowing rod 305 installed on the connecting frame 311 and the material supporting plate 301 will be the same as the thickness of the first template buckle 7 on the first support table 405.

[0064] Next, move the sliding carriage 402 installed on the fixed base 401. When the sliding carriage 402 moves, it will drive the claws 403 on both sides of the first support table 405 to move, causing the claws 403 to contact both sides of the first template buckle 7 on the first support table 405. After the claws 403 contact the first template, the sliding carriage 402 will stop moving. At this time, the distance between the two limit plates 404 installed on the sliding carriage 402 will be the same as the diameter of the first template buckle 7 on the first support table 405.

[0065] It should be noted that in order to ensure that the material buckle 9 on the stripper plate can move smoothly, the distance between the air blowing rod 305 and the material supporting plate 301 can be adjusted by rotating the adjusting bolt 406, so that the distance between the air blowing rod 305 and the material supporting plate 301 is slightly greater than the thickness of the first template buckle 7. At the same time, the distance between the two limit plates 404 is slightly greater than the diameter of the first template buckle 7. Such a setting can limit the material buckle 9 on the stripper plate through the mutual cooperation of the limit plates 404 and the air blowing rod 305, avoiding the material buckle 9 from slipping off the stripper plate due to lack of limit when being blown by the air blowing rod 305.

[0066] In order to enable the air blowing rod 305 to blow the material buckle 9 to move along the stripper plate, a main air duct 306 and a plurality of air outlet holes 307 are provided on the air blowing rod 305. The air outlet holes 307 are inclined along the moving direction of the material buckle 9, and the air flow will blow the material buckle 9 to move after flowing out from the air outlet holes 307.

[0067] Then, move the block 410 along the cross rail 408 under the mutual cooperation of the cross rail 408 and the transverse slider 409. Since the inclined push block 411 contacts the bearing 418 fixed on the fixed block 417, the sliding friction between the fixed block 417 and the inclined push block 411 can be converted into rolling friction through the bearing 418, reducing the mutual cooperation friction force and extending the service life of the equipment. Therefore, when the block 410 moves, it will push the limit block 416 to move under the cooperation of the inclined push block 411 and the bearing 418 on the fixed block 417. When the limit block 416 moves, the limit rail 413 and the limit slider 414 will slide relative to each other, and at the same time, the tension spring 415 will be stretched. Then, place the second template buckle 8 on the second support table 407. After the second template buckle 8 is placed on the second support table 407, release the block 410. After the block 410 is released, the tension spring 415 will shorten. When the tension spring 415 shortens, it will pull the limit block 416 to move in the reverse direction along the limit rail 413. The reversely moving limit block 416 will push the block 410 to move in the reverse direction through the contact between the fixed block 417 and the inclined push block 411, as Figure 1 and Figure 6 shown. Until the block 410 moves to contact the edge of the second template buckle 8 on the second support table 407, the block 410 will stop moving, and the second template buckle 8 will be clamped and fixed on the second support table 407. At the same time, the stop rod 419 will be asFigure 7 As shown, the material buckle 9 is blocked, so that the length of the material buckle 9 extending from the output end of the material supporting plate 301 can be guaranteed to be half of the diameter of the material buckle 9.

[0068] It should be noted that in order to ensure that the moving distance of the limiting block 416 that can be pushed by the cooperation of the inclined pushing block 411 and the fixed block 417 is half of the moving distance of the clamping block 410, the orthographic projection of the clamping block 410 on the horizontal plane is as Figure 10 shown, where D = 2L, and according to trigonometric functions, tan(A) = L / D, then ∠A = arctan1 / 2, approximately 26.565°.

[0069] During operation, the material buckle 9 will move onto the material supporting plate 301 under the action of the external feeding mechanism 3. After the material buckle 9 moves onto the material supporting table, the gas in the main air duct 306 on the air blowing rod 305 will flow out along the air outlet holes 307, blowing the material buckle 9 to move on the stripping plate. During the movement of the material buckle 9, the limiting plate 404 will limit the material buckle 9, and when the material buckle 9 moves along the material supporting plate 301 and contacts the stop rod 419, the material buckle 9 will stop moving.

[0070] At this time, the linear cylinder 608 on the material moving mechanism 6 is in a contracted state. The rotating driving arm 610 connected to the output end of the linear cylinder 608 will drive the rotating shaft 609 to rotate, so that the positioning post on the blanking die 612 installed at the free end of the swing arm 611 is located below the material buckle 9 at the output end of the material supporting plate 301. At this time, the lifting cylinder 604 will shorten, and under the cooperation of the feeding slider 602 and the feeding rail 601, it will drive the lifting frame 603 to move towards the feeding plate 605. After the lifting frame 603 moves, it will drive the swing arm 611 to move upward through the connecting seat 606. If the positioning post on the blanking die 612 is just aligned with the sewing hole on the material buckle 9, the positioning post will be inserted into the positioning hole on the material buckle 9; if the positioning post on the blanking die 612 is not aligned with the sewing hole on the material buckle 9, after the blanking die 612 moves upward, the positioning post will push the material buckle 9 upward, and the upward-moved material buckle 9 will contact the pressing member 312, which can prevent the material buckle 9 from falling.

[0071] At this time, the reset cylinder 509 is in an extended state, and the extended reset cylinder will push the positioning plate 504 to move upward for reset, as Figure 3 and Figure 5 shown. The stabilizing rod 506 installed on the support frame 2 passes through the positioning plate 504. At this time, the second spring 505 on the stabilizing rod 506 above the positioning plate 504 is in a state of being compressed and storing energy under the action of the stop block 510.

[0072] Then, the positioning plate 504 will start to move downward, and the reset cylinder 509 on the positioning mechanism 5 will start to shorten. When the reset cylinder 509 shortens, the second spring 505 will stretch and release energy, pushing the positioning plate 504 downward. The positioning plate 504 is driven by the cross slide 503 to approach the stripping plate under the cooperation of the positioning rail 501 and the positioning slider 502. When the positioning plate 504 approaches the stock plate 301, it will drive the positioning motor 507 to approach the stock plate 301. After the positioning motor 507 moves, the rotating rubber particle 508 at the output end will contact the material buckle 9 above the feeding die 612. Then, the positioning motor 507 will drive the rotating rubber particle 508 to rotate. Due to the frictional force between the material buckle 9 and the rotating rubber particle 508, the material buckle 9 will also rotate. The sewing hole on the material buckle 9 will align with the positioning post on the feeding die 612 during the rotation. Since the rotating rubber particle 508 is made of rubber and has elasticity, after the sewing hole on the material buckle 9 rotates to align with the positioning post on the feeding die 612, it will push the material buckle 9 downward, inserting the positioning post on the feeding die 612 into the sewing hole on the material buckle 9 to limit the material buckle 9.

[0073] After the positioning motor 507 finishes rotating, the positioning cylinder 509 will drive the positioning motor 507 to move upward through the positioning plate 504. At this time, the second spring 505 will be compressed again to store energy. Meanwhile, the output end of the limit cylinder 421 on the limit block 416 will drive the stop lever 419 to retract through the connecting rod 420. After the stop lever 419 retracts, the linear cylinder 608 will start to extend, driving the rotating shaft 609 to rotate through the rotating drive arm 610, causing the rotating shaft 609 to drive the swing arm 611 to rotate. The feeding die 612 installed on the swing arm 611 drives the material buckle 9 to move. Synchronously, the lifting cylinder 604 will extend, pushing the lifting frame 603 downward and driving the swing arm 611 to move downward together through the connecting seat 606, causing the swing arm 611 to move downward while making a rotational motion.

[0074] Finally, the feeding die 612 will drive the material buckle 9 to be sent into the button input end of the button sewing machine under the drive of the swing arm 611. When the material buckle 9 on the feeding die 612 is taken away by the button sewing machine, the linear cylinder 608 will shorten, driving the rotating shaft 609 to rotate in the reverse direction through the rotating drive arm 610. At the same time, the lifting cylinder 604 will also shorten, driving the connecting seat 606 to move upward through the lifting frame 603, causing the swing arm 611 to move upward while rotating. Finally, the swing arm 611 drives the feeding die 612 to move to the output end of the stock plate 301 again. After the feeding die 612 moves to the output end of the stock plate 301, the limit cylinder 421 will extend, driving the stop lever 419 to extend through the connecting rod 420, so that the stop lever 419 blocks the material buckle 9 again.

[0075] In this embodiment, multiple sets of slide rails and sliders are adopted. Such a setting can not only reduce the friction between various sliding components and extend the service life of the equipment, but also improve the bearing capacity and precision of the equipment. At the same time, the positioning cylinder 509 and the support frame 2, as well as the lifting cylinder 604 and the lifting frame 603, are all connected by floating joints 10.

However, the content described above is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
