[0038] The present invention provides an automated door placket buttonhole device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0039] See also Figure 1 , Figure 2 The present invention provides an automated door placket buttonhole device, comprising a frame 1, a panel 11 fixedly connected to the frame 1, a feeding platform carriage 12 capable of reciprocating along the length direction of the panel 11, a right clamping mechanism 2 fixedly connected to the feeding platform carriage 12, a right clamping driving assembly 3 for driving the right clamping mechanism 2 to reciprocate along the length direction of the panel 11, a left clamping mechanism 4 connected to the right clamping driving assembly 3, and a synchronous moving assembly for driving the right clamping mechanism 2 and the left clamping mechanism 4 to synchronously reciprocate along the length direction of the panel 11. A dynamic driving component 5, a left side suction mechanism 6, a right side suction mechanism 7 and a buttonhole car 13 arranged between the left side clamping mechanism 4 and the right side clamping mechanism 2; the left side suction mechanism 6 is used to position and suck the left part of the shirt; the right side mechanism 7 is used to position the right part of the shirt; the buttonhole car 13 is located between the left side suction mechanism 6 and the right side mechanism 7, and is used to sew buttonholes on the shirt placket placed on the feeding platform slide 12 and clamped on the left side clamping mechanism 4 and the right side clamping mechanism 2.

[0040] It should be noted that the terms left, right, upstream and downstream in the technical solution are only used to indicate the direction and are not intended to be limiting. In this embodiment, the right side is used as the upstream / feeding side for description.

[0041] In actual application, a material unloading platform is provided on the right side of the frame 1, and the operator can stack the shirts to be sewn with buttonholes on the material unloading platform, and then load the shirts one by one onto the feeding platform carriage 12. Before loading, according to the length of the shirt, the right clamp driving assembly 3 is controlled by the control system to drive the right clamp mechanism 2 at the far right (initial state) to gradually move to the left to the set position, so that the distance between the left clamp mechanism 4 and the right clamp mechanism 2 can be adjusted according to the actual length of the shirt. Then, when loading, the part of the shirt placket is positioned by the left side position adsorption mechanism 6 and the right side position mechanism 7, so as to ensure that the shirt placket will not be skewed, and the rest of the shirt is placed on the upper surface of the feeding platform carriage 12. Then, under the action of the left side clamp mechanism 4 and the right side clamp mechanism 2, the shirt after positioning is fixed to prevent the shirt from displacement during the processing. Next, under the action of the synchronous moving driving assembly 5, the feeding platform carriage 12 is driven, and the shirt, the left clamping mechanism 4 and the right clamping mechanism 2 on it are synchronously moved to the left, and with the cooperation of the buttonhole car 13, multiple buttonholes can be sewn on the placket of the shirt. After the buttonholes are sewn, the left clamping mechanism 4 and the right clamping mechanism 2 are operated again to release the fixation of the shirt, and the material unloading operation can be carried out. Finally, each mechanism is reset to the initial state.

[0042] In the above-mentioned device, the right clamping mechanism 2 is moved independently by the right clamping driving assembly 3; the synchronous movement driving assembly 5 is set to enable the left clamping mechanism 4 and the right clamping mechanism 2 to move synchronously; through the movement of the right clamping mechanism 2, the distance between the right clamping mechanism 2 and the left clamping mechanism 4 can be changed, thereby improving the practicality and applicability of the buttonhole device; in addition, the left side position adsorption mechanism 6 and the right side position adsorption mechanism 7 are set, which not only play a role in positioning the shirt, but also can adsorb the side wall of the shirt, thereby correcting the positioning deviation of the shirt.

[0043] See also Figure 3 and Figure 4 In some embodiments, the right clamp mechanism 2 includes a right moving seat 22 fixedly connected to the right clamp driving assembly 3, a right clamp plate 25 fixedly connected to the right moving seat 22, and a right clamp lifting driving assembly 26, and a right clamp 27 arranged on the output end of the right clamp lifting driving assembly 26; the right clamp lifting driving assembly 26 is used to drive the right clamp 27 to contact or separate from the right clamp plate 25. When the right clamp driving assembly 3 is running, it drives the right clamp plate 25, the right clamp lifting driving assembly 26 and the right clamp 27 to move synchronously through the displacement of the right moving seat 22. The right clamp 27 is located above the right clamp plate 25, and the right clamp 27 is driven to rise or fall by the right clamp lifting driving assembly 26, so that the right part of the shirt placed on the upper surface of the right clamp plate 25 is fixed or released.

[0044] See also Figure 3 and Figure 4 In some embodiments, the right clamp lifting drive assembly 26 is a right clamp cylinder with an output end facing upwards, and a right button switch 261 for controlling its start and stop is provided on the right clamp cylinder, and the right button switch 261 is connected to a right pressing plate 262, and the right pressing plate 262 is used to control the start and stop of the right button switch 261. When in use, the shirt is loaded onto the upper surface of the right clamp plate 25, and the right pressing plate 262 is manually pressed downward to control the right button switch 261 to turn on, so that the right clamp cylinder drives the right clamp 27 to move downward to clamp the shirt.

[0045] See also Figure 3 and Figure 4 In some embodiments, the right clamp driving assembly 3 includes a right moving plate 31 slidably connected to the synchronous moving driving assembly 5, a right clamp motor seat 32 disposed on the upper surface of the right moving plate 31, a right clamp motor 33 disposed on the right clamp motor seat 32, a right clamp driving wheel 34 drivingly connected to the output end of the right clamp motor 33, a first guide shaft support 35 fixedly connected to the right moving plate 31, a right clamp driven wheel 36 rotatably disposed on the first guide shaft support 35, and a right clamp synchronous belt 37 wound between the right clamp driving wheel 34 and the right clamp driven wheel 36; the right moving seat 22 is fixedly connected to the right clamp synchronous belt 37. Specifically, the right clamp synchronous belt 37 is driven to rotate synchronously by the forward or reverse rotation of the right clamp motor 33, so that the right moving seat 22 fixedly connected to the right clamp synchronous belt 37 moves synchronously to the left or right.

[0046] See also Figure 3 and Figure 4In some embodiments, a right clamping synchronous belt 37 fixing seat 221 is bent on the right movable seat 22, and a right clamping synchronous belt 37 adjusting seat 222 is provided on one side of the right clamping synchronous belt 37 fixing seat 221, and a through hole 223 for the right clamping synchronous belt 37 to pass through is provided on the right clamping synchronous belt 37 fixing seat 221 and the right clamping synchronous belt 37 adjusting seat 222, and a pressure clamp 224 for clamping the right clamping synchronous belt 37 is also provided on the right clamping synchronous belt 37 fixing seat 221 and the right clamping synchronous belt 37 adjusting seat 222; an adjusting screw 225 is provided on the right clamping synchronous belt 37 adjusting seat 222, and a threaded hole is provided on the right clamping synchronous belt 37 fixing seat 221, and the rod body of the adjusting screw 225 is threadedly connected to the threaded hole. In actual use, by twisting the adjusting screw 225 to move the right clamp synchronous belt 37 adjusting seat 222 toward the right clamp synchronous belt 37 fixing seat 221, the distance between the right clamp synchronous belt 37 adjusting seat 222 and the right clamp synchronous belt 37 fixing seat 221 can be adjusted. Since the right clamp synchronous belt 37 adjusting seat 222 and the right clamp synchronous belt 37 fixing seat 221 are both provided with a pressure clamp 224, therefore, by changing the position of the right clamp synchronous belt 37 adjusting seat 222 and the right clamp synchronous belt 37 fixing seat 221, the tightness of the right clamp synchronous belt 37 located on the outer part of the right clamp synchronous belt 37 adjusting seat 222 and the right clamp synchronous belt 37 fixing seat 221 can be tightened, thereby ensuring the smooth movement of the right movable seat 22.

[0047] See also Figure 4 Specifically, the through holes 223 are arranged in multiple numbers (three in the figure), and multiple pads are arranged below the first guide shaft support 35, so that the right clamp driving wheel 34 and the left clamp driven wheel are coaxial. Multiple through holes 223 are provided on the right clamp synchronous belt 37 fixing seat 221 and the right clamp synchronous belt 37 adjusting seat to adapt to the position of the right clamp synchronous belt 37 and ensure the horizontality of the right clamp synchronous belt 37.

[0048] See also Figure 3 and Figure 4 In some embodiments, the upper surface of the right movable plate 31 is provided with a right slide rail 23 extending along the length direction thereof, and a right slider 24 is slidably provided on the right slide rail 23, and the upper surface of the right slider 24 is fixedly connected to the lower surface of the right movable seat 22. In this embodiment, the right movable seat 22 is L-shaped, and the right slide rail 23 and the right slider 24 are used to improve the stability of the right movable seat 22 when it reciprocates left and right, thereby preventing the shirt clamped between the right clamp 27 and the right clamping plate 25 from being wrinkled due to vibration.

[0049] See also Figure 3 and Figure 5In some embodiments, the left clamp mechanism 4 includes a left positioning plate 41 fixed to the frame 1, a left movable seat 44 slidably arranged along the length direction of the left positioning plate 41, a left clamp plate 45 fixed to the left movable seat 44 and a left clamp lifting drive assembly 46, and a left clamp 47 arranged on the output end of the left clamp lifting drive assembly 46; the left clamp lifting drive assembly 46 is used to drive the left clamp 47 to contact or separate with the left clamp plate 45. Similarly, when the right clamp mechanism 2 moves to the left under the action of the synchronous moving drive assembly 5, the left clamp mechanism 4 moves to the left synchronously. The left movable seat 44 connected to the right clamp mechanism 2 is used to realize the left movement of the left clamp plate 45, the left clamp lifting drive assembly 46 and the left clamp 47. Similarly, the left clamp 47 is located above the left clamp plate 45, and the left clamp 47 is driven to rise or fall by the left clamp lifting drive assembly 46, so that the left part of the shirt placed on the upper surface of the left clamp plate 45 is fixed or released.

[0050] See also Figure 3 and Figure 5 In some embodiments, the left clamp lifting drive assembly 46 is a left clamp cylinder with an output end facing upward, and a left button switch 461 for controlling its start and stop is provided on the left clamp cylinder. The left button switch 461 is connected to a left press plate 462, and the left press plate 462 is used to control the start and stop of the left button switch 461. The operation mode of the left clamp lifting drive assembly 46 is the same as that of the right clamp lifting drive assembly 26. In addition, the left button switch 461 and the right button switch 261 are both electrically connected to the control system. When the left button switch 461 and the right button switch 261 are both in the on state, it means that the loading is completed and the buttonhole machine starts to start and run.

[0051] See also Figure 3 and Figure 5 In some embodiments, the upper surface of the left positioning plate 41 is provided with a left slide rail 42 extending along the length direction thereof, and a left slider 43 is slidably provided on the left slide rail 42, and the upper surface of the left slider 43 is fixedly connected to the lower surface of the left moving seat 44. Similarly, the cooperation between the left slide rail 42 and the left slider 43 improves the moving stability of the left moving seat 44.

[0052] See also Figure 3 and Figure 5In some embodiments, the left movable seat 44 and the right movable plate 31 are connected via a connecting seat 48; the connecting seat 48 includes a second guide shaft support 481 fixedly connected to the lower surface of the left movable seat 44, a push rod 482 passing through the center of the second guide shaft support 481, a joint 483 connected to the end of the push rod 482, and a connecting rod (not shown in the figure) for connecting the joint 483 and the right movable plate 31. Specifically, the spacing between the left movable seat 44 and the right movable plate 31 is determined by the length of the push rod 482, so the spacing between the left movable seat 44 and the right movable plate 31 can be changed by changing the depth of the push rod 482 inserted into the second guide shaft support 481. The above structure is simple and can also achieve fine adjustment of the spacing. More specifically, the push rod 482 and the joint 483 are threadedly connected, which can further simplify the assembly and disassembly process.

The synchronous belt linear module is used to enable the right moving plate 31 to reciprocate along the length direction of the synchronous belt linear module, and the additional auxiliary slider 52 is provided according to the large surface of the right moving plate 31, so as to further improve the moving stability of the right moving plate 31.

[0054] See also Figure 6-Figure 8In some embodiments, the left-side suction mechanism 6 includes a suction alignment base plate 61 fixedly connected to the upper surface of the buttonhole vehicle 13, a left-side propulsion driving member 62 arranged on the suction alignment base plate 61, a suction hood 63 connected to the output end of the left-side propulsion driving member 62, and an L-shaped left-side plate 64 fixed to the suction hood 63; the left-side propulsion driving member 62 is used to drive the suction hood 63 and the left-side plate 64 to propel toward the shirt; the inner cavity of the suction hood 63 is connected to the suction device, and the suction hood 63 is provided with a plurality of suction ports 6312 on the side wall facing the shirt; the suction device is used to draw air from the suction hood 63 so that the suction ports 6312 adsorb the side wall of the shirt. In actual application, the left side push drive 62 starts to run, driving the suction hood 63 and the left side plate 64 to push toward the shirt side / operation side, so that the operator can place the shirt on the upper surface of the L-shaped horizontal plate of the left side plate 64 for positioning. The front side of the vertical plate of the left side plate 64 is used to limit the shirt. Then, the suction device is used to put the suction hood 63 in a negative pressure state, so that the side of the shirt is adsorbed through multiple suction ports 6312, so that the side of the shirt is close to the side walls of the suction hood 63 and the left side plate 64. After positioning, the left clamping mechanism 4 and the right clamping mechanism 2 clamp the shirt again, and then the buttonhole car 13 is started to perform the buttonhole operation on the corresponding position of the shirt.

For example, the left lateral propulsion motor 621 rotates forward / reversely, driving the left lead screw 622 to rotate clockwise / counterclockwise, so that the left nut seat 623 reciprocates on the left lead screw 622, thereby driving the left lateral plate 64 to move toward the shirt, or away from the shirt. The above structure has high movement accuracy.

[0056] See also Figure 6In some embodiments, a left sensor 624 is further provided beside the left side propulsion motor 621, and a left sensing screw 625 is provided on the rear side of the left side plate 64. The left sensor 624 is used to sense the left sensing screw 625. The left sensor 624 is electrically connected to the control system, and drives the left sensing screw 625 to move synchronously through the left side plate 64.
