Description

Technical Field

[0001] This utility model belongs to the field of garment processing technology, specifically relating to a folding device for epaulette lining. Background Technology

[0002] Shoulder straps are rank insignia worn on the shoulders of uniforms. Shoulder straps require a certain degree of rigidity, so they are typically constructed using a rigid plate covered with lining fabric. The lining fabric is bonded to one side of the rigid plate, and the edges of the lining fabric are folded to the back for bonding. Due to the shape limitations of shoulder straps and the requirements for fine processing, the folding of the lining fabric is currently mostly done manually. Although some manufacturers have attempted to use automated folding equipment, existing equipment mostly uses cylinders to push pressure plates against the edges of the lining fabric to complete the folding and bonding. The drawback of this automated folding solution is that it requires the shoulder strap to be placed in the center of a ring of cylinders, and there is also a pressing and fixing structure above the shoulder strap. Each cylinder alternately operates to complete the folding action of each side of the shoulder strap. This not only results in a complex overall structure but also occupies almost all the space on the workbench, making it very cramped for manual or robotic arms to pick up and place shoulder straps at the workstation, which is detrimental to improving work efficiency. Therefore, it has not been widely adopted. Utility Model Content

[0003] This utility model provides a device for folding the epaulette lining, which aims to improve the efficiency of folding the epaulette lining.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a epaulette lining hemming device, comprising: The frame is equipped with a rotary drive, which has a fixed frame and an annular rotary table; The template is rotatably connected to the turntable and has a mold groove suitable for embedding epaulettes. The template is connected to the fixed frame through a transmission component, which is used to drive the template to rotate when the turntable rotates. The rotation direction of the template is opposite to the rotation direction of the turntable and the rotation angle is equal. The rolling mechanism is fixedly connected to the center of the fixed frame and includes multiple rolling components distributed circumferentially. The adjacent spacing angle of each rolling component is used to correspond one-to-one with the angles of each epaulette. The template aligns with each rolling component in sequence as the rotary table revolves. The rolling components aligned with the template are used to roll the edges of the epaulettes embedded in the mold groove.

[0005] In one possible implementation, the rolling mechanism includes a telescopic assembly and various rolling assemblies; wherein the telescopic assembly is vertically arranged at the center of the fixed frame with its telescopic end facing upward; the various rolling assemblies are spaced apart on the outer periphery of the telescopic end of the telescopic assembly; each rolling assembly is used to roll the rotary table radially along the rotary table under the telescopic drive of the telescopic assembly.

[0006] In some embodiments, the telescopic component includes: The fixing sleeve is vertically fixed to the center of the fixing frame; The sliding sleeve is slidably fitted onto the fixed sleeve in the vertical direction, and each rolling assembly is connected to the outer periphery of the sliding sleeve; The telescopic drive component is fixed to the fixed frame and located inside the fixed sleeve. The output end of the telescopic drive component is connected to the sliding sleeve.

[0007] For example, the rolling assembly includes a swing arm and an elastic strut. One end of the swing arm is hinged to a sliding sleeve and the other end is provided with a pressure roller. One end of the elastic strut is hinged to the sliding sleeve and the other end is hinged to the swing arm. The elastic strut is vertically aligned with the swing arm and applies a downward elastic pushing force to the swing arm.

[0008] For example, transmission components include: A spur gear is coaxially connected to the template and located below the rotary table; The spur gear ring is fitted onto a fixed frame and is coaxial with the rotary table. The spur gear ring meshes with a spur gear and both have the same number of teeth.

[0009] In one possible implementation, the rotary drive includes: The slewing bearing has an inner ring fixed to the frame and a fixed bracket fixedly connected to the inner ring, and a slewing disc coaxially fixed to the top of the outer ring. The rotary drive component is fixed to the frame and connected to the outer ring drive.

[0010] In some embodiments, the top of the mounting bracket is provided with a frustum suitable for supporting the rolling assembly, the frustum being flush with the upper surface of the rotary table.

[0011] For example, the epaulette lining hemming device also includes a controller and a position detection component, wherein the controller is electrically connected to the position detection component, the rotary drive, and the rolling mechanism respectively; wherein the position detection component is used to detect the rotation angle of the rotary table.

[0012] For example, the position detection component includes a proximity sensor and multiple edge-folding sensing blocks; the proximity sensor is located on the bottom surface of the rotary table and aligned vertically with the template, and each sensing block is arranged around the fixing frame and corresponds one-to-one with each rolling component.

[0013] In some embodiments, the position detection component further includes an infeed / outfeed level sensor block located between two adjacent folded edge sensor blocks.

[0014] The beneficial effects of the shoulder patch lining hemming device provided by this utility model are as follows: Compared with the prior art, the shoulder patch lining hemming device of this utility model can form a revolution around the rolling mechanism by following the rotation of the rotary drive when the rotary drive works. At the same time, the template can also transmit the rotational power of the rotary disk to itself to form a self-rotation motion based on the drive of the transmission component. Since the revolution and self-rotation of the template are opposite in direction and the rotation angles are equal, the angle and posture of the template relative to the fixed frame remain unchanged during the revolution of the template following the rotary disk. On this basis, the rolling components of the rolling mechanism are set with corresponding circumferential interval angles on the outer periphery of the fixed frame corresponding to the angles of the shoulder patch. This allows the template to align the corresponding edge of the shoulder patch with the rolling component when aligning each rolling component. The lining hemming is completed by rolling the side edge of the shoulder patch from the inside to the outside (from the center of the rotary disk to the outer periphery) through the rolling component. The lining hemming of each side of the shoulder patch can be completed after the rotary disk has rotated once.

[0015] Since the rolling mechanism is located in the center of the rotary table and the template is located on the rotary table, the epaulette edge is rolled from the inside out by various rolling components to complete the folding. This not only makes the overall structure simpler, but more importantly, it can fully avoid the space around the template. Whether the epaulette is picked up and put into the mold groove manually or by a robot, the convenience of the picking and putting process can be improved, thereby promoting the efficiency of epaulette lining folding and making it suitable for widespread application.

In the description of this application, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0020] Please refer to the following: Figures 1 to 7 The epaulette lining hemming device provided by this utility model will now be described. The epaulette lining hemming device includes a frame 10, a template 20, and a rolling mechanism 30. A rotary drive 11 is provided on the frame 10, the rotary drive 11 having a fixed frame 111 and an annular rotary disk 112. The template 20 is rotatably connected to the rotary disk 112 and has a mold groove 21 suitable for embedding the epaulette 50. The template 20 and the fixed frame 111 are connected by a transmission component 22, which drives the template 20 to rotate as the rotary disk 112 rotates. The rotation direction is opposite to the rotation direction of the rotary table 112 and the rotation angle is equal; the rolling mechanism 30 is fixedly connected to the center of the fixed frame 111 and includes multiple rolling components 31 distributed circumferentially. The adjacent interval angle of each rolling component 31 is used to correspond one-to-one with the angle of each epaulette 50; wherein, the template 20 follows the rotary table 112 to revolve and aligns with each rolling component 31 in sequence, and the rolling component 31 aligned with the template 20 is used to roll the edge of the epaulette 50 embedded in the mold groove 21.

[0021] It should be noted that, in this embodiment, the template 20 serves two purposes: firstly, it positions the epaulette 50 through the mold groove 21 to prevent the epaulette 50 from sliding or misaligning during the folding process; secondly, when the epaulette 50 is embedded in the mold groove 21, the edge of the lining fabric 51 can be raised based on the pressure of the groove opening. In this way, when the rolling assembly 31 rolls the edge of the epaulette 50, the raised lining fabric 51 can be folded over the back of the epaulette 50. Since the lining fabric 51 is pre-coated with adhesive, the folded lining fabric 51 is tightly bonded to the back edge of the epaulette 50 under the rolling force of the rolling assembly 31.

[0022] It should be understood that the shape of the epaulette 50 is usually pentagonal, specifically a pentagonal structure with one end set as a triangle, which is a rectangle or trapezoid. In this embodiment, the number of rolling components 31 is the same as the number of sides of the epaulette 50. That is, the rolling mechanism 30 includes five rolling components 31 distributed circumferentially. During the revolution of the template 20 driven by the rotary table 112, the epaulette 50 aligns with each rolling component 31 in sequence. Moreover, since the self-rotation of the template 20 driven by the transmission component 22 is opposite to the direction of revolution and the rotation angle is equal, it can be ensured that when the epaulette 50 aligns with each rolling component 31, one of its edges will be aligned with the rolling component 31 along the radial direction of the rotary table 112. This makes the rolling component 31 roll perpendicular to the edge of the epaulette 50, thereby ensuring the quality of the folded edge.

[0023] Considering that the template 20 will form a small protrusion (the thickness of the template 20) on the upper surface of the rotary table 112, in order to ensure that the rolling assembly 31 aligned with the template 20 rolls onto the template 20 in a stable and smooth manner, in this embodiment, the diameter of the roller 313 at the roller end of the rolling assembly 31 should be more than five times the thickness of the template 20. At the same time, the edge of the template 20 can be chamfered to form a smooth transition between the upper surface of the template 20 and the upper surface of the rotary table 112, thereby avoiding jamming when the roller 313 rolls to the edge of the template 20, and ensuring that the roller 313 can smoothly roll from the upper surface of the rotary table 112 to the upper surface of the template 20.

[0024] Compared with the prior art, the epaulette lining hemming device provided in this embodiment allows the template 20 to rotate around the rolling mechanism 30 while the rotary drive 11 is working, forming a revolution around the rolling mechanism 30. Simultaneously, the template 20 can also transmit the rotational force of the rotary disk 112 to itself based on the drive of the transmission component 22, forming a self-rotation motion. Since the revolution and self-rotation directions of the template 20 are opposite and the rotation angles are equal, the angle and posture of the template 20 relative to the fixed frame 111 remain unchanged during the revolution of the template 20 following the rotary disk 112. Based on this, the rolling components 31 of the rolling mechanism 30 are set with corresponding circumferential interval angles on the outer periphery of the fixed frame 111 corresponding to the corner angles of the epaulette 50. This allows the template 20 to align each rolling component 31 so that the corresponding edge of the epaulette 50 faces the rolling component 31. The epaulette 50 is rolled by the rolling component 31 from the center of the rotary table 112 outward to the periphery to complete the hemming of the lining fabric 51. The hemming of the lining fabric 51 on each side of the epaulette 50 is completed after the rotary table 112 has rotated one revolution.

[0025] Since the rolling mechanism 30 is located in the central area of ​​the rotary table 112 and the template 20 is located on the rotary table 112, the edge of the shoulder patch 50 is rolled from the inside to the outside by each rolling component 31 to complete the folding. This not only makes the overall structure simpler, but more importantly, it can fully avoid the space around the template 20. Whether the shoulder patch 50 is picked up and put into the mold groove 21 manually or by a robot, the convenience of the picking and putting process can be improved, thereby promoting the folding efficiency of the shoulder patch 50 lining 51, which is suitable for widespread application.

[0026] In some embodiments, see Figure 2 The rolling mechanism 30 includes a telescopic component 32 and various rolling components 31; wherein, the telescopic component 32 is vertically arranged at the center of the fixed frame 111 with its telescopic end facing upward; the various rolling components 31 are spaced apart on the outer periphery of the telescopic end of the telescopic component 32; each rolling component 31 is used to roll the rotary table 112 radially along the rotary table 112 under the telescopic drive of the telescopic component 32.

[0027] The extension and retraction ends of the rolling assembly 31 and the telescopic assembly 32 can be connected by a hinge. When the telescopic assembly 32 extends upward, it can pull the rolling assembly 31 to swing towards the center of the rotary table 112. When the telescopic assembly 32 retracts downward, it can push the rolling assembly 31 to swing towards the edge of the rotary table 112. The telescopic assembly 32 can simultaneously drive each rolling assembly 31 to move synchronously.

[0028] It should be understood that since each rolling component 31 operates synchronously, and since only one rolling component 31 is aligned with the template 20, each movement of the telescopic component 32 involves one rolling component 31 rolling the edge of the epaulette 50, while the other rolling components 31 roll directly on the rotary table 112. The purpose is to drive each rolling component 31 to operate synchronously through a single telescopic component 32, thereby achieving the sequential rolling and folding process of each side of the epaulette 50 during the rotation of the rotary table 112, which simplifies the overall structure of the rolling mechanism 30 and saves space.

[0029] As one specific embodiment of the aforementioned telescopic component 32, please refer to Figure 2 The telescopic assembly 32 includes a fixed sleeve 321, a sliding sleeve 322, and a telescopic drive member 323; wherein, the fixed sleeve 321 is vertically fixed to the center of the fixed frame 111; the sliding sleeve 322 is slidably sleeved on the fixed sleeve 321 in the vertical direction, and each rolling assembly 31 is connected to the outer periphery of the sliding sleeve 322; the telescopic drive member 323 is fixed to the fixed frame 111 and located inside the fixed sleeve 321, and the output end of the telescopic drive member 323 is connected to the sliding sleeve 322.

[0030] The cooperation between the fixed sleeve 321 and the sliding sleeve 322 creates a space inside them that can accommodate the telescopic drive component 323, thereby achieving a hidden arrangement of the telescopic drive component 323. The telescopic drive component 323 can be an electric telescopic rod or a telescopic cylinder. The telescopic drive component 323 drives the sliding sleeve 322 to move up and down, thereby driving the various rolling components 31 to move synchronously. The structure is simple and compact.

[0031] For example, such as Figure 2 As shown, in this embodiment, the rolling assembly 31 includes a swing arm 311 and an elastic support rod 312. One end of the swing arm 311 is hinged to the sliding sleeve 322 and the other end is provided with a pressure roller 313. One end of the elastic support rod 312 is hinged to the sliding sleeve 322 and the other end is hinged to the swing arm 311. The elastic support rod 312 is aligned vertically with the swing arm 311 and applies a downward elastic pushing force to the swing arm 311.

[0032] The projection of the swing arm 311 on the rotary table 112 is located in the radial direction of the rotary table 112. The elastic support rod 312 is aligned vertically with the swing arm 311, which allows the pressure roller 313 to move radially along the rotary table 112 during the swing of the swing arm 311, thereby ensuring the quality of the rolling and folding of the corresponding shoulder strap 50 edge. The elastic support rod 312 can be a structure of gas spring or spring mounted on a telescopic cylinder. The elastic support rod 312 applies an elastic pushing force to the swing arm 311, thereby ensuring that the pressure roller 313 always rolls on the rotary table 112 during the swing of the swing arm 311 driven by the lifting and lowering of the sliding sleeve 322. More importantly, it ensures that the pressure roller 313 can apply sufficient rolling force when rolling the edge of the shoulder strap 50, thereby ensuring the reliability of the bonding between the folded lining 51 and the back edge of the shoulder strap 50.

[0033] As an optional embodiment of the aforementioned transmission component 22, please refer to Figure 3 The transmission component 22 includes a spur gear 221 and a spur gear ring 222; the spur gear 221 is coaxially connected to the template 20 and located below the rotary table 112; the spur gear ring 222 is fitted onto the fixed frame 111 and is coaxial with the rotary table 112, and the spur gear ring 222 meshes with the spur gear 221 and the two have the same number of teeth.

[0034] The spur gear 221 and the spur gear ring 222 form an external meshing. As the rotary table 112 rotates, the spur gear 221 rolls against the spur gear ring 222 to obtain a driving force that drives the template 20 to rotate in the opposite direction. Since the rotation angle of the rotary table 112 is the same as the angle that the spur gear 221 rolls over on the spur gear ring 222, and the number of teeth of the spur gear 221 and the spur gear ring 222 are equal, the rotation angle of the spur gear 221 is equal to the angle that it rolls over on the spur gear ring 222. Therefore, the angle of rotation of the template 20 driven by the spur gear 221 is the same as the angle of revolution driven by the rotary table 112.

[0035] For some possible implementations, please refer to [link / reference]. Figure 1 The rotary drive 11 includes a rotary bearing 113 and a rotary drive 114; the inner ring of the rotary bearing 113 is fixed to the frame 10 and a fixed bracket 111 is fixedly connected to the inner ring, and a rotary disk 112 is coaxially fixed to the top of the outer ring; the rotary drive 114 is fixed to the frame 10 and is connected to the outer ring for transmission.

[0036] The rotary drive component 114 can specifically be a motor. Here, the slewing bearing 113 can be understood as a common slewing support bearing in the prior art. The inner ring of the slewing bearing 113 is fixed, and the space inside the inner ring provides installation space for the fixing frame 111. The outer ring is the rotating end that is connected to the rotary drive component 114 for transmission. The transmission connection method can be gear transmission, that is, the output end of the rotary drive component 114 is fitted with a drive gear, and the outer ring of the slewing bearing 113 is provided with a driven gear ring. The drive gear meshes with the driven gear ring to realize the rotational drive of the outer ring. The overall structure is simple and compact.

[0037] In some embodiments, combined with Figure 2 and Figure 3As can be seen, the top of the fixing frame 111 is provided with a frustum 1111 suitable for supporting the rolling assembly 31, and the frustum 1111 is flush with the upper surface of the rotary table 112. The interior of the annular rotary table 112 provides space for installing the fixing frame 111. The frustum 1111 is provided here to fill the gap between the fixing frame 111 and the rotary table 112. The frustum 1111 and the rotary table 112 form an integral planar structure. When the rolling assembly 31 moves towards the center of the rotary table 112, the upper surface of the frustum 1111 can provide support for the rolling assembly 31, avoiding the rolling assembly 31 from becoming suspended and unstable, thereby ensuring the movement stability of the rolling assembly 31.

[0038] It should be understood that, in this embodiment, the shoulder epaulette lining hemming device also includes a controller 40 and a position detection component. The controller 40 is electrically connected to the position detection component, the rotary drive 11, and the rolling mechanism 30, respectively. The position detection component is used to detect the rotation angle of the rotary table 112.

[0039] Under normal circumstances, the rotation angle of the rotary disk 112 can be controlled by the servo drive of the rotary drive component 11. In this embodiment, a position detection component is set to further improve the rotation angle accuracy of the rotary disk 112. The position detection component can detect the position of the template 20 aligned with each rolling component 31 and feed back an electrical signal to the controller 40. After receiving the electrical signal, the controller 40 controls the rotary drive component 11 to stop moving, and at the same time the rolling mechanism 30 moves once. After the rolling mechanism 30 finishes moving, the rotary drive component 11 continues to move, and stops again when the template 20 aligns with the next rolling component 31, and at the same time the rolling mechanism 30 moves once again. This process is repeated until the rotary drive component 11 drives the rotary disk 112 to rotate one revolution, thus completing the folding action on each side of the shoulder patch 50.

[0040] Specifically, see Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the position detection component includes a proximity sensor 41 and multiple edge-folding sensing blocks 42; the proximity sensor 41 is located on the bottom surface of the rotary table 112 and is aligned vertically with the template 20, and each sensing block is arranged around the fixing frame 111 and corresponds one-to-one with each rolling component 31.

[0041] The proximity sensor 41 receives an electrical signal when it approaches each hem sensing block 42 and feeds it back to the controller 40. The positions of each hem sensing block 42 are corresponding to the positions of each rolling assembly 31, while the proximity sensor 41 corresponds to the position of the template 20. Therefore, when the proximity sensor 41 approaches each hem sensing block 42 and feeds an electrical signal to the controller 40, the rotary drive 11 stops moving, ensuring that the template 20 and the corresponding rolling assembly 31 are aligned. The control logic is simple and clear, and the use of a single proximity sensor 41 in conjunction with multiple hem sensing blocks 42 results in a simple and compact detection structure. Since the proximity sensor 41 and each hem sensing block 42 are located in the space below the rotary table 112, the upper surface of the rotary table 112 is kept flat and unobstructed, providing ample space for manual or robotic arm handling of the shoulder patches 50.

[0042] In some embodiments, such as Figure 6 As shown, the position detection component also includes an infeed / outfeed position sensor block 43, which is located between two adjacent folded edge sensor blocks 42.

[0043] When the proximity sensor 41 aligns with the infeed / outfeed position sensing block 43, it can also receive an electrical signal feedback to the controller 40. At this time, the controller 40 can control the rotary drive 11 to stop moving, so that the template 20 stops at an angle that is not aligned with any rolling component 31, thereby facilitating manual or robotic arm to pick up and put the shoulder patch 50 into the mold groove 21.

[0044] It should be noted that when the proximity sensor 41 moves with the rotary table 112 to align with the feed / discharge position sensing block 43, since it is not necessary to roll the shoulder epaulette 50, the controller 40 can receive an electrical signal to control the rotary drive 11 to stop moving, without controlling the rolling mechanism 30 to operate, thereby avoiding the rolling mechanism 30 from running unloaded.

[0045] Specifically, considering that the shoulder insignia 50 has five folds, the rolling mechanism 30 needs to operate five times for the rotary table 112 to rotate one revolution (see...). Figure 7 (The lining fabric 51 of the epaulette 50 edges ABCDE is folded sequentially.) This process is accompanied by the controller 40 receiving five electrical signals (see... Figure 6 The proximity sensor 41 is sequentially aligned with the folded edge sensing block 42 at angles A1-B1-C1-D1-E1, and the rotary table 112 rotates to the angle corresponding to the proximity sensor 41 and the inlet / outlet material level sensing block 43. Figure 6 When the sixth electrical signal is received at position F1, the controller 40 can determine the upper or lower material position by counting. At this time, it only controls the rotary drive 11 to stop moving and does not control the rolling mechanism 30 to move.

[0046] It should be noted that this embodiment is intended to configure the hardware required to implement the above control logic. Those skilled in the art should understand that the above logic for controlling the rotation angle of the rotary table 112 based on the cooperation of the proximity sensor 41 and each edge sensing block 42 and the feed / discharge position sensing block 43 is a commonly used control logic in the prior art, so it will not be described in detail here.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
