Description

Technical Field

[0001] The present application relates to the technical field of sewing equipment, and particularly to an upper die mechanism for a pocket attaching machine and a pocket attaching machine. Background Art

[0002] Pocket attaching machines are mainly used for the sewing operation of pockets. Flat sewing and bartacking can be completed at one time, and are applicable to the sewing of various back pockets of jeans, shirt pockets, and other irregular-shaped parts in garment processing.

[0003] During the working process of a pocket attaching machine, first, a pocket-shaped fabric is laid on a lower template, and then the upper die mechanism in the hemming mechanism cooperates with the lower template. The suction component in the upper die mechanism sucks the lower template to clamp the pocket-shaped fabric. The hemming knives in the hemming mechanism are inserted from below both sides of the pocket-shaped fabric to complete the hemming action of the pocket-shaped fabric. After hemming, the upper die mechanism and the lower template are separated to complete the reset of the hemming mechanism.

[0004] During the hemming process, the upper die mechanism and the lower template need to meet precise dimensional cooperation to constrain the shape of the pocket-shaped fabric during the hemming process. During the reset process, the upper die mechanism and the lower template need to be easily separated to facilitate continuous operation. In the prior art, it is difficult to balance the cooperation requirements under different working conditions, which further limits the design space of the upper die mechanism and the lower template, and has a negative impact on automatic control.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0040] The front-back direction in this application is a relative direction. For example, in Figure 1 the relative front side is Figure 1 the upper side on one side in Figure 1 the lower side on one side in

[0041] Refer to Figures 1 to 2, one embodiment of the present application provides an upper die mechanism 400 for a pocket attaching machine, including a fixed seat 410. The fixed seat 410 is used to install other components. When applied to the pocket attaching machine, the fixed seat 410 is connected to the hemming device and driven by the hemming device. The fixed seat 410 has opposite front and rear sides.

[0042] The upper female die 420 is connected to the fixed seat 410 and moves with the fixed seat 410. The upper female die 420 is provided with a cavity 421 for placing the bag-shaped fabric and the lower template 200. The cavity 421 is arranged on the side of the upper female die 420 facing away from the fixed seat 410.

[0043] The driving assembly is installed on the fixed seat 410. There are multiple sets of driving assemblies. Each set of driving assemblies includes a suction member 430 for magnetically attracting the lower template 200 and a pushing member 440 for driving the lower template 200 to disengage from the cavity 421. The suction force of the suction member 430 drives the lower template 200 into the cavity. Correspondingly, the pushing force of the pushing member 440 drives the lower template 200 out of the cavity.

[0044] In this embodiment, the suction member 430 can ensure the mutual fitting of the upper die mechanism 400 and the lower template 200 during the hemming process to ensure the fitting accuracy. The pushing member 440 can achieve the rapid separation of the upper die mechanism 400 and the lower template 200 during the reset process. Thus, while ensuring the cooperation accuracy of the upper die mechanism 400 and the lower template 200, it is easy to separate, realizing automatic control. Multiple sets of driving assemblies act on different parts of the lower template 200 respectively.

[0045] In terms of the specific setting of the upper female mold 420, the upper female mold 420 includes a template 422 and a frame 423. The template 422 and the frame 423 enclose to form a mold cavity 421. In one embodiment, the template 422 is connected to the fixed seat 410, and the frame 423 extends along the edge of the template 422 and encloses the mold cavity 421 with the template 422. The template 422 and the frame 423 are of an integral structure or are formed by separate connection. The frame 423 protrudes compared with the template 422. The template 422 is provided with a first avoidance opening 424, and the suction member 430 corresponds to the position of the first avoidance opening 424 and is exposed in the mold cavity 421. There are multiple first avoidance openings 424. The first avoidance opening 424 is adapted to the shape of the suction member 430. When the suction member 430 is located in the first avoidance opening 424, the bag-shaped fabric will not extend out of the mold cavity 421 through the first avoidance opening 424. Similarly, the template 422 is provided with a second avoidance opening 425, and the pushing member 440 enters and exits the mold cavity 421 through the second avoidance opening 425. There are multiple second avoidance openings 425. The second avoidance opening 425 is adapted to the shape of the pushing member 440. When the pushing member 440 is located in the second avoidance opening 425, the bag-shaped fabric will not extend out of the mold cavity 421 through the second avoidance opening 425. The size of the second avoidance opening 425 is smaller than that of the first avoidance opening 424 to reduce the influence of the opening on the shape of the mold cavity 421. The first avoidance opening 424 and the second avoidance opening 425 can be separately arranged or integrally connected and arranged. Multiple sets of driving components independently set the first avoidance opening 424 and / or the second avoidance opening 425. Or at least two sets of driving components share the first avoidance opening 424 and / or the second avoidance opening 425. For example, there is a connected avoidance hole on the template 422 for each suction member 430 and pushing member 440 to be exposed in the mold cavity 421.

[0046] In terms of the cooperation details between the upper female mold 420 and the driving components, the frame 423 is open at the rear side of the template 422. The side edges of the front half of the template 422 are connected to the frame 423, and both the suction member 430 and the pushing member 440 are located in the front half of the template 422. The suction member 430 is close to the front side of the template 422. Figure 1 In it, the ratio range between the distance L1 between the geometric center of at least one suction member 430 and the edge of the front side of the template 422 and the distance L2 between the geometric center of the suction member 430 and the edge of the rear side of the template 422 is 0.1 to 0.4. Further, the suction members 430 are arranged side by side in the left-right direction of the template 422, where the left-right direction is perpendicular to the front-rear direction mentioned above. The pushing member 440 is located at the rear side of the suction member 430. The pushing member 440 and the suction member 430 are aligned in the front-rear direction. When the suction members 430 corresponding to the pushing members 440 are aligned with each other, the pushing members 440 are aligned with each other.

[0047] In terms of the specific settings of the driving component, the attracting member 430 is an electromagnet, and there is no strict limit on the quantity. For example, the attracting member 430 is 2 to 6 pieces arranged at intervals. The attracting member 430 is flush with or slightly retracted from the template 422. In this embodiment, the suction force of the attracting member 430 is perpendicular to the plane where the template 422 is located. The pushing member 440 is a cylinder, including a cylinder block 441 installed on the fixed seat 410 and a piston cylinder 442 slidably installed in the cylinder block 441. The piston cylinder 442 enters and exits the mold cavity 421 through the second avoidance port 425. The retracted piston cylinder 442 is flush with or slightly retracted from the template 422. In this embodiment, the moving direction of the piston cylinder 442 is perpendicular to the plane where the template 422 is located.

[0048] Figure 2 In [description], the fixed seat 410 includes a main body, a first adapter seat 411 and a second adapter seat 412 installed on the main body. The main body is plate-shaped and is used to provide installation positions for the first adapter seat 411 and the second adapter seat 412. The first adapter seat 411 and the second adapter seat 412 are located between the template 422 and the main body. The first adapter seat 411 is located on the front side of the second adapter seat 412. Both the attracting member 430 and the pushing member 440 are arranged on the first adapter seat 411. The first adapter seat 411 includes a pushing part 413 at the same height as the second adapter seat 412 and an attracting part 414 retracted compared to the pushing part 413. The attracting member 430 is installed on the attracting part 414, and the pushing member 440 is installed on the pushing part 413. The template 422 is assembled to the main body of the fixed seat 410 through the second adapter seat 412 and the attracting part 414. The second adapter seat 412 and the attracting part 414 extend in the left-right direction and are connected to the template 422 through the middle part to provide a stable installation effect. The first avoidance port 424 corresponds to the attracting part 414, and the second avoidance port 425 corresponds to the pushing part 413.

[0049] Combined with Figures 3 to 4 , in one embodiment of the present application, a pocket attaching machine is further provided, including an upper die mechanism 400 and a lower template 200 that cooperate with each other to clamp the bag-shaped fabric to perform hemming. The upper die mechanism 400 is the upper die mechanism 400 for the pocket attaching machine in the present application. In this embodiment, the lower template 200 adopts a split deformation structure, that is, it includes a plurality of unit plates that can move relative to each other. There is no strict limit on the shape and quantity of the unit plates. For example, there are 2 to 6 pieces. The lower template 200 has an expanded working state and a relatively narrowed state. In the working state, the size of the lower template 200 matches the size of the mold cavity 421 to support the inner edge of the hemming part of the bag-shaped fabric. For example Figure 4As shown in the figure. The lower template 200 is connected to a corresponding driving mechanism 300 for driving the lower template 200 to switch states. In one embodiment, the multiple unit plates include a middle plate 201 and a left plate 202 and a right plate 203 arranged on both sides of the middle plate 201. The middle plate 201 can move in the front-rear direction and provide space for the relative movement of the left plate 202 and the right plate 203 in the left-right direction. In the working state of the lower template 200, the front edges of the middle plate 201, the left plate 202, and the right plate 203 are mutually connected to form a continuously extending outer contour, which generally corresponds to the bag-shaped fabric. After hemming, the lower template 200 switches to the narrowing state, the middle plate 201 moves away from the front side of the template 422 in the front-rear direction, and the left plate 202 and the right plate 203 approach each other to surround the front side of the middle plate 201. The middle plate 201 can also be arranged to be stacked above or below the left plate 202 and the right plate 203. In different states, the middle plate 201 remains stationary relative to the driving mechanism 300, and the left plate 202 and the right plate 203 move relative to the middle plate 201 to realize the unfolding and narrowing of the lower template 200. In this embodiment, the pushing member 440 and the suction member 430 are configured in a set, and each unit plate corresponds to at least one set of the pushing member 440 and the suction member 430. The suction member 430 interacts with one end of each unit plate away from the driving mechanism 300, and the pushing member 440 acts on the part of the unit plate between the driving mechanism 300 and the suction member 430 and is close to the suction member 430. During the working process, each set of the pushing member 440 and the suction member 430 are in the same working state or different working states simultaneously to meet the requirements of different working conditions.

[0050] Other parts of the patch pocket machine can be implemented in combination with the prior art and will not be elaborated here.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved at the same time.

[0052] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
