Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to a double-head template exchange device. Background Technology

[0002] A template exchanger is a device used in conjunction with a computerized pattern-making machine to automatically change sewing templates for the machine, primarily used in the production and processing of clothing, footwear, and other similar products. For example, Chinese Patent Application No. 201920814238.6 discloses an automatic template exchanger, comprising a frame, a template gripping device, a gripping adjustment device, a template lifting device, and a template placement device. The gripping adjustment device is located on top of the frame, the template gripping device is mounted on the gripping adjustment device, the template lifting device is mounted on the frame, and the template placement device is adjacent to and fixed to the top of the template lifting device, forming a multi-layer drawer-type structure.

[0003] However, the existing template exchange is only paired with one computerized pattern sewing machine. When the computerized pattern sewing machine is sewing the template, the template exchange is in a paused state, resulting in low template exchange efficiency. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a dual-head template exchange device equipped with two computerized pattern machines, which can improve template exchange efficiency.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution: A dual-head template exchange device includes a first pattern machine, a template exchange, and a second pattern machine. The first pattern machine includes a first sewing table and a first sewing head, and the second pattern machine includes a second sewing table and a second sewing head. The template switch includes a template tray, a gripping mechanism, and a first translation mechanism. The template tray is aligned with the first sewing table and the second sewing table. The first translation mechanism drives the gripping mechanism to move along the first horizontal direction. The gripping mechanism includes a first gripper and a second gripper. When the first translation mechanism drives the gripping mechanism to move along the first horizontal direction to a side closer to the first pattern making machine, the first gripper is located on the first sewing table, and the second gripper is located on the template tray. When the first translation mechanism drives the gripping mechanism to move along the first horizontal direction to a side closer to the second pattern making machine, the first gripper is located on the template tray, and the second gripper is located on the second sewing table.

[0006] Furthermore, the template switch also includes a tray lifting mechanism. There are multiple template trays, and each template tray is arranged at intervals along the vertical direction on the tray lifting mechanism. The tray lifting mechanism drives the tray tray to lift and lower, so that one of the template trays is aligned with the first sewing table and the second sewing table.

[0007] Furthermore, the gripping mechanism is positioned opposite to each template tray along a second direction; the template exchange also includes a second translation mechanism, which drives the gripping mechanism to move along the second horizontal direction; when the second translation mechanism drives the gripping mechanism to move along the second direction to a side close to each template tray, the gripping mechanism is located on a template tray aligned with the first sewing table and the second sewing table; when the second translation mechanism drives the gripping mechanism to move along the second direction to a side away from each template tray, the gripping mechanism is located outside each template tray.

[0008] Furthermore, the first horizontal direction is perpendicular to the second horizontal direction.

[0009] Furthermore, the spacing between each template tray is the same height.

[0010] Furthermore, the template tray is provided with a limiting block or limiting groove on the side facing the gripping mechanism, for corresponding engagement with the limiting groove or limiting block on the sewing template; the second translation mechanism also has a limiting point on the second horizontal direction, the limiting point being located between the two sides along the second horizontal direction; when the second translation mechanism drives the gripping mechanism to move along the second direction to the limiting point, the limiting groove or limiting block on the sewing template engages with the limiting block or limiting groove on the template tray; when the second translation mechanism drives the gripping mechanism to move along the second direction to a side close to each template tray, the limiting groove or limiting block on the sewing template separates from the limiting block or limiting groove on the template tray.

[0011] Furthermore, the first sewing table includes a first sewing area and a first exchange area, the first sewing area being located below the first sewing machine head, and the first exchange area being located on the side facing the template exchanger; the first pattern machine also includes a first moving mechanism for driving the sewing template to move between the first sewing area and the first exchange area.

[0012] Furthermore, the second sewing table includes a second sewing area and a second exchange area, the second sewing area being located below the second sewing machine head, and the second exchange area being located on the side facing the template exchanger; the second pattern machine also includes a second moving mechanism for driving the sewing template to move between the second sewing area and the second exchange area.

[0013] This utility model has the following beneficial effects: The dual-head template exchange device of this utility model uses the template exchanger in conjunction with the first and second pattern-making machines. The first and second grippers on the gripping mechanism drive the various sewing templates to be exchanged between the template tray and the first and second pattern-making machines respectively, thereby improving template exchange efficiency. When the gripping mechanism is located closer to the first pattern-making machine, the first gripper can grip the sewing templates already sewn on the first sewing table, and the second gripper can grip the unsewn sewing templates on the template tray. When the gripping mechanism moves from the side closer to the first pattern-making machine to the side closer to the second pattern-making machine, the first gripper can move the gripped sewing templates from... The first sewing table is transferred to the template tray for retrieval, while the second gripper can transfer the grasped sewing template from the template tray to the second sewing table for sewing. Similarly, when the gripping mechanism is located near the second pattern machine, the first gripper can grasp the unsewn sewing template on the template tray, and the second gripper can grasp the sewn template on the second sewing table. When the gripping mechanism moves from the side near the second pattern machine to the side near the first pattern machine, the first gripper can transfer the grasped sewing template from the template tray to the first sewing table for sewing, while the second gripper can transfer the grasped sewing template from the second sewing table to the template tray for retrieval.

[0022] Example 1 like Figure 1-3 As shown, a dual-head template exchange device includes a first pattern machine 1, a template exchange 2, and a second pattern machine 3. The first pattern machine 1 includes a first sewing table 11 and a first sewing head 12, and the second pattern machine 3 includes a second sewing table 31 and a second sewing head 32. The template switch 2 includes a template tray 21, a gripping mechanism 22, and a translation mechanism 23. The template tray 21 is aligned with the first sewing table 11 and the second sewing table 31. The translation mechanism 23 drives the gripping mechanism 22 to move. The gripping mechanism 22 includes a first gripper 221 and a second gripper 222. When the translation mechanism 23 drives the gripping mechanism 22 to move closer to the first pattern making machine 1, the first gripper 221 is located on the first sewing table 11, and the second gripper 222 is located on the template tray 21. When the translation mechanism 23 drives the gripping mechanism 22 to move closer to the second pattern making machine 3, the first gripper 221 is located on the template tray 21, and the second gripper 222 is located on the second sewing table 31.

[0023] The dual-head template exchange device of this utility model uses the template exchanger 2 in conjunction with the first pattern machine 1 and the second pattern machine 3. The first gripper 221 and the second gripper 222 on the gripping mechanism 22 drive each sewing template a to be exchanged between the template tray 21 and the first pattern machine 1 and the second pattern machine 3, respectively, thereby improving template exchange efficiency. When the gripping mechanism 22 is located closer to the first pattern machine 1, the first gripper 221 can grasp the sewing template a that has already been sewn on the first sewing table 11, and the second gripper 222 can grasp the unsewn sewing template a on the template tray 21. When the gripping mechanism 22 moves from the side closer to the first pattern machine 1 to the side closer to the second pattern machine 3, the first gripper 221 can transfer the grasped sewing template a from the first sewing table 11. The first gripper 222 can move the grasped sewing template a from the template tray 21 to the second sewing table 31 for sewing. Similarly, when the gripping mechanism 22 is located near the second pattern machine 3, the first gripper 221 can grasp the unsewn sewing template a on the template tray 21, and the second gripper 222 can grasp the sewn sewing template a on the second sewing table 31. When the gripping mechanism 22 moves from the side near the second pattern machine 3 to the side near the first pattern machine 1, the first gripper 221 can move the grasped sewing template a from the template tray 21 to the first sewing table 11 for sewing, and the second gripper 222 can move the grasped sewing template a from the second sewing table 31 to the template tray 21 for retrieval.

[0024] The sewing template a, which is transferred to the template tray 21 for recycling by the first gripper 221 or the second gripper 222, can be manually removed from the template tray 21 by an operator and the unsewn sewing template a can be placed back on the template tray 21, or it can be automatically removed from the template tray 21 by a robot and the unsewn sewing template a can be placed back on the template tray 21.

[0025] Meanwhile, in order to reduce the number of times the sewing template a is taken from and taken from the template tray 21 and further improve the template exchange efficiency, the template exchanger 2 also includes a tray lifting mechanism 24. There are multiple template trays 21, and each template tray 21 is arranged at intervals along the vertical direction on the tray lifting mechanism 24. The tray lifting mechanism 24 drives the trays to lift and lower so that one of the template trays 21 is aligned with the first sewing table 11 and the second sewing table 31.

[0026] In one operating mode, the pallet lifting mechanism 24 first drives each template pallet 21 to rise and fall, so that the first template pallet 21 is aligned with the first sewing table 11 and the second sewing table 31. Then, the translation mechanism 23 drives the gripping mechanism 22 to move, so that the first gripper 221 transfers the sewing template a placed on the first template pallet 21 to the first sewing table 11 for sewing. Then, the pallet lifting mechanism 24 drives each template pallet 21 to rise and fall again, so that the second template pallet 21 is aligned with the first sewing table 11 and the second sewing table 31. Then, the translation mechanism 23 drives the gripping mechanism 22 to move. The second gripper 222 moves the sewing template a placed on the second template tray 21 to the second sewing table 31 for sewing, while the first gripper 221 moves the sewing template a placed on the first sewing table 11 to the second template tray 21 for retrieval. Then, the tray lifting mechanism 24 drives each template tray 21 to rise and fall, aligning the third template tray 21 with the first sewing table 11 and the second sewing table 31. The translation mechanism 23 then drives the gripping mechanism 22 to move, so that the first gripper 221 moves the sewing template a placed on the third template tray 21 to the second sewing table 31. Sewing is performed on the first sewing table 11, while the second gripper 222 transfers the sewing template a placed on the second sewing table 31 to the third template tray 21 for retrieval; this process continues until the tray lifting mechanism 24 drives each template tray 21 to rise or fall, so that the last template tray 21 is aligned with the first sewing table 11 and the second sewing table 31. Then, the translation mechanism 23 drives the gripping mechanism 22 to move, so that the first gripper 221 or the second gripper 222 transfers the sewing template a placed on the last template tray 21 to the first sewing table 11 or the second sewing table 31 for sewing. Simultaneously, the second gripper 222 or the first gripper 221 transfers the sewing template a placed on the second sewing table 31 or the first sewing table 11 to the last template tray 21 for recycling; finally, the tray lifting mechanism 24 drives each template tray 21 to rise and fall, so that the first template tray 21 is realigned with the first sewing table 11 and the second sewing table 31, and the translation mechanism 23 drives the gripping mechanism 22 to move, so that the first gripper 221 or the second gripper 222 transfers the sewing template a placed on the first sewing table 11 or the second sewing table 31 to the first template tray 21 for recycling.

[0027] In another operating mode, the pallet lifting mechanism 24 first drives each template pallet 21 to rise and fall, so that the first template pallet 21 is aligned with the first sewing table 11 and the second sewing table 31. Then, the translation mechanism 23 drives the gripping mechanism 22 to move, so that the first gripper 221 transfers the sewing template a placed on the first template pallet 21 to the first sewing table 11 for sewing. Then, the pallet lifting mechanism 24 drives each template pallet 21 to rise and fall again, so that the second template pallet 21 is aligned with the first sewing table 11 and the second sewing table 31. After alignment, the translation mechanism 23 drives the gripping mechanism 22 to move, so that the second clamp moves the sewing template a placed on the second template tray 21 to the second sewing table 31 for sewing; then, the tray lifting mechanism 24 drives each template tray 21 to rise and fall, so that the first template tray 21 is realigned with the first sewing table 11 and the second sewing table 31, and the translation mechanism 23 drives the gripping mechanism 22 to move, so that the first gripper 221 moves the sewing template a placed on the first sewing table 11 back to the second sewing table 31 for sewing. The template is retrieved from the first template tray 21; then, the tray lifting mechanism 24 drives each template tray 21 to rise and fall, so that the third template tray 21 is realigned with the first sewing table 11 and the second sewing table 31. The translation mechanism 23 then drives the gripping mechanism 22 to move, so that the first gripper 221 transfers the sewing template a placed on the third template tray 21 to the first sewing table 11 for sewing; next, the tray lifting mechanism 24 drives each template tray 21 to rise and fall, so that the second template tray 21 is aligned with the first sewing table 11 and the second sewing table 31. The sewing table 11 and the second sewing table 31 are realigned, and the translation mechanism 23 drives the gripping mechanism 22 to move, so that the second gripper 222 transfers the sewing template a placed on the second sewing table 31 back to the second template tray 21 for recycling; and so on, after the sewing template a on the (n+1)th template tray 21 is sent out, the previous sewing template a is recycled to the nth template tray 21, and then the sewing template a on the (n+2)th template tray 21 is sent out, so that each sewing template a is recycled back to the template tray 21 where it was initially placed.

[0028] Preferably, the spacing height between each template pallet 21 is the same, so that when the pallet lifting mechanism 24 drives each template pallet 21 to lift, it does not need to consider the difference in spacing between each template pallet 21. That is, the output of the pallet lifting mechanism 24 is the same each time it drives the lifting, thereby simplifying the drive control of the pallet lifting mechanism 24.

[0029] The first pattern making machine 1, the template exchanger 2, and the second pattern making machine 3 are arranged sequentially along the first horizontal direction, and the first gripper 221 and the second gripper 222 are arranged side by side along the first horizontal direction. The translation mechanism 23 includes a first translation mechanism 231, which is used to drive the gripping mechanism 22 to move along the first horizontal direction. When the first translation mechanism 231 drives the gripping mechanism 22 to move along the first horizontal direction to the side close to the first pattern making machine 1, the first gripper 221 is located on the first sewing table 11, and the second gripper 222 is located on the template tray 21. When the first translation mechanism 231 drives the gripping mechanism 22 to move along the first horizontal direction to the side close to the second pattern making machine 3, the first gripper 221 is located on the template tray 21, and the second gripper 222 is located on the second sewing table 31.

[0030] The gripping mechanism 22 is positioned opposite to each template tray 21 along a second direction; the template exchange 2 also includes a second translation mechanism 232, which drives the gripping mechanism 22 to move along the second horizontal direction; when the second translation mechanism 232 drives the gripping mechanism 22 to move along the second direction to a side close to each template tray 21, the gripping mechanism 22 is located on the template tray 21 aligned with the first sewing table 11 and the second sewing table 31; when the second translation mechanism 232 drives the gripping mechanism 22 to move along the second direction to a side away from each template tray 21, the gripping mechanism 22 is located outside each template tray 21.

[0031] The dual-head template exchange device of this utility model drives the gripping mechanism 22 to move along the second horizontal direction through the second translation mechanism 232 to avoid the lifting and lowering of each template tray 21. Before each lifting and lowering of each template tray 21, the second translation mechanism 232 first drives the gripping mechanism 22 to move along the second horizontal direction to the outside of each template tray 21. After each lifting and lowering of each template tray 21, the second translation mechanism 232 then drives the gripping mechanism 22 to move along the second horizontal direction to the template tray 21 aligned with the first sewing table 11 and the second sewing table 31.

[0032] Preferably, the first horizontal direction is perpendicular to the second horizontal direction.

[0033] like Figure 4As shown, the template tray 21 has a limiting block 202 or limiting groove 201 on the side facing the gripping mechanism 22, which is used to correspondingly engage with the limiting groove 201 or limiting block 202 on the sewing template a; the second translation mechanism 232 also has a limiting point in the second horizontal direction, which is located between the two sides along the second horizontal direction; when the second translation mechanism 232 drives the gripping mechanism 22 to move along the second direction to the limiting point, the limiting groove 201 or limiting block 202 on the sewing template a is correspondingly engaged with the limiting block 202 or limiting groove 201 on the template tray 21; when the second translation mechanism 232 drives the gripping mechanism 22 to move along the second direction to the side close to each template tray 21, the limiting groove 201 or limiting block 202 on the sewing template a is correspondingly separated from the limiting block 202 or limiting groove 201 on the template tray 21.

[0034] The gripping mechanism 22 picks up and places the sewing template a at the limiting point. That is, after the limiting groove 201 or limiting block 202 on the sewing template a is correspondingly engaged with the limiting block 202 or limiting groove 201 on the template tray 21, the gripping mechanism 22 releases the sewing template a. Before the limiting groove 201 or limiting block 202 on the sewing template a is correspondingly separated from the limiting block 202 or limiting groove 201 on the template tray 21, the gripping mechanism 22 first grips the sewing template a tightly.

[0035] When the template tray 21 has the limiting block 202, the sewing template a has the limiting groove 201 that fits into it; when the template tray 21 has the limiting groove 201, the sewing template a has the limiting block 202 that fits into it.

[0036] like Figure 1 As shown, the first sewing table 11 includes a first sewing area 112 and a first exchange area 111. The first sewing area 112 is located below the first sewing machine head 12, and the first exchange area 111 is located on the side facing the template exchanger 2. The first pattern machine 1 also includes a first moving mechanism 13, which is used to drive the sewing template a to move between the first sewing area 112 and the first exchange area 111.

[0037] The second sewing table 31 includes a second sewing area 312 and a second exchange area 311. The second sewing area 312 is located below the second sewing machine head 32, and the second exchange area 311 is located on the side facing the template exchanger 2. The second pattern machine 3 also includes a second moving mechanism 33 for driving the sewing template a to move between the second sewing area 312 and the second exchange area 311.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
