Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a template-changing sewing machine. Background Technology

[0002] In the garment and footwear manufacturing industry, templates are often used to assist in processing certain parts that are difficult to process directly. In existing template machines, the exchange between the template to be processed and the completed template is typically achieved using two gripping claws located on the left and right sides of the machine. One claw feeds the template to be processed, while the other picks up the completed template. During the template processing and exchange process, manual supervision and assistance are often required, making fully automated operation impossible. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a template exchange sewing machine that can automatically transport and output templates alternately, effectively reducing the working time consumed by template installation and retrieval, and improving the overall efficiency of template exchange.

[0004] To achieve the above objectives, this utility model provides a template-changing sewing machine, comprising:

[0005] A sewing machine having a processing area;

[0006] A template exchange device adjacent to the sewing machine includes an exchange frame and a template lifting mechanism mounted on the exchange frame. The template lifting mechanism is connected to several support seats arranged sequentially from top to bottom, and a first clamping component is provided on one side of each support seat.

[0007] The first template clamping and feeding mechanism, located between the template exchange device and the sewing machine, is used to transport the template on the carrier to the processing area;

[0008] The material placement platform is located on one side of the template interaction device. The material placement platform is provided with a material placement area, a second template clamping mechanism for transporting the templates in the material placement area to the carrier seat, and several cover plate grooves and material grooves for placing templates and materials.

[0009] And several templates for carrying materials.

[0010] Furthermore, electronic automatic identification tags are provided on each template, and a grating assembly is provided on the exchange frame. The working area of ​​the grating assembly surrounds the support base. An identification sensor for identifying the aforementioned electronic automatic identification tags (51) is provided on the sewing machine. The automatic identification tag can be an RFID tag, QR code, or barcode, etc. In conjunction with the identification sensor, the corresponding sewing program can be read, significantly improving the automation level and operational safety of the sewing equipment. The grating assembly can effectively prevent human bodies and foreign objects from entering the template exchange device, preventing operator injury and equipment damage.

[0011] Furthermore, the template lifting mechanism includes a lifting bracket and a template lifting motor fixed to the lifting bracket. A first slide rail is provided on the lifting bracket, and a first support plate is slidably connected to the first slide rail. The template lifting motor is connected to a lead screw assembly and to the first support plate to realize the lifting of the first support plate. A plurality of bearing seats are equidistantly arranged on the first support plate. The lead screw assembly can be a ball screw, and a closed-loop control mode of motor + ball screw can be used to precisely control the lifting height, ensure the alignment consistency of the template, sewing machine head and the first template clamping mechanism, avoid misalignment during template transportation, ensure the accuracy of each template change, and thus improve the efficiency of equipment operation and the quality of processing.

[0012] Furthermore, the first clamping assembly includes a first clamping cylinder fixedly connected to the first support plate, and the first clamping cylinder is connected to a first clamping member. The first clamping cylinder, in conjunction with the first clamping member, clamps and fixes the template entering the bearing seat, preventing template wobbling and ensuring template output for sewing, thereby improving the stability of equipment operation.

[0013] Furthermore, the first support plate is also equipped with sensors matching the number of the support seats. These sensors can quickly identify the support seats at corresponding positions and read the corresponding information to facilitate subsequent sewing operations.

[0014] Furthermore, the first template clamping mechanism includes a first clamping main seat fixed to one side of the exchange frame and a first clamping motor fixed to the first clamping main seat. The two ends of the first clamping main seat extend to the template exchange device and the sewing machine, respectively. A second slide rail and a first belt assembly are provided on the first clamping main seat. A second clamping bracket is slidably connected to the second slide rail. The first belt assembly is connected to both the first clamping motor and the second clamping bracket. A third slide rail and a transmission connector are provided on the second clamping bracket. A third clamping bracket is movably connected to the third slide rail. A second clamping cylinder is fixedly connected to the third clamping bracket and is connected to the transmission connector. The third clamping cylinder is also fixedly connected to the third clamping bracket, and a second clamping member is connected to the third clamping cylinder. This clamping mechanism achieves high-speed, high-precision, and flexible template transmission, completely solving the bottleneck problems of traditional sewing equipment that rely on manual handling and have low positioning efficiency. Its modular design allows for seamless connection with template exchange devices and sewing machines for alternating template sewing, resulting in a high degree of automation and the ability to meet the needs of different sewing processes.

[0015] Furthermore, it also includes a first support member fixed to the cylinder body of the third clamping bracket or the third clamping cylinder. The front end of the first support member forms a first connecting portion. The second clamping member is rotatably mounted on the first connecting portion via a movable shaft. One end of the second clamping member is connected to the third clamping cylinder, and the other end of the second clamping member is a second clamping portion. The cooperation between the third clamping cylinder and the second clamping member enables precise clamping of the template. The swing-arm clamping action further strengthens the clamping of the template, ensuring stable template conveying operations.

[0016] Furthermore, the second template clamping mechanism includes a second clamping motor and a fourth slide rail fixedly connected to the lower part of the material placement platform. A second clamping connector is movably connected to the fourth slide rail. A through slot matching the fourth slide rail is provided on the material placement platform. The other end of the second clamping connector passes through the through slot and is connected to a second clamping main seat. The second clamping connector is connected to the second clamping motor via a second transmission belt assembly. A second clamping assembly is connected to the second clamping main seat. By fixing the second clamping motor to the lower part of the material placement platform and combining it with the vertical through-type layout of the fourth slide rail and the through slot, the overall height of the equipment is effectively reduced, forming a compact three-dimensional transmission structure. At the same time, by using the material placement platform as a rigid load-bearing base, vibration caused by the cantilever effect during transmission is significantly suppressed, ensuring structural stability under high-speed movement.

[0017] Furthermore, the second clamping assembly includes a fourth clamping cylinder, a second support member fixed to the second clamping main seat or the cylinder body of the fourth clamping cylinder, and a third clamping member. The front end of the second support member forms a second connecting portion, and the third clamping member is rotatably mounted on the second connecting portion via a movable shaft. One end of the third clamping member is connected to the fourth clamping cylinder, and the other end of the third clamping member is the third clamping portion. Using the fourth clamping cylinder in conjunction with the third clamping member to clamp and fix the template entering the material feeding platform provides a stable feeding environment, preventing the template from shifting due to external forces and causing disordered material discharge within the template, thereby improving the quality of product processing operations.

[0018] Furthermore, the template is provided with several positioning posts, a first positioning block that works in conjunction with the first clamping assembly, and a first clamping structure and a second clamping structure that respectively cooperate with the first template feeding mechanism and the second template feeding mechanism. This allows the template to work in conjunction with the operation of various devices / mechanisms, improving the overall smoothness and stability of the equipment's operation and effectively enhancing the quality of the processing work.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. This utility model, by setting up a material placement platform, and in conjunction with the set cover plate groove and material groove, enables operators to conveniently select various components to be processed and stack them on the template, realizing multi-process operation. Then, in conjunction with the second template clamping and conveying mechanism, the stacked templates are automatically transported to the template exchange device, improving the applicability of the product and the processing efficiency.

[0021] 2. The template exchange device of this utility model adopts a multi-layer stacking method, which can clamp multiple templates at one time. With the first template clamping mechanism and the second template clamping mechanism, it can realize the automated alternating delivery and output of templates, effectively reducing the working time consumed by template installation and retrieval, and improving the overall efficiency of template exchange.

[0022] 3. This utility model sets an electronic automatic identification tag on the template. When the template is transported to the sewing machine, the identification sensor on the sewing machine automatically reads the tag data and calls the preset sewing program (stitch density, presser foot pressure, thread tension, sewing shape, etc.). The sewing machine performs the corresponding sewing program according to the received information, reducing manual setting errors, supporting rapid template changeover, and significantly improving the automation level and intelligence of the sewing equipment. An infrared grating array is arranged around the exchange frame to form a three-dimensional detection network, covering the working area of ​​the support seat, which can effectively prevent people and foreign objects from entering the template exchange device, preventing operator injury and equipment damage.

[0043] In this embodiment, the first template clamping mechanism 3 is disposed between the template exchange device 2 and the sewing machine 1, and is used to transport the template 5 on the support 225 to the processing area 11, such as... Figure 1 and Figure 5 As shown,

[0044] The first template clamping mechanism 3 includes a first clamping main seat 31 fixed to one side of the exchange frame 21 and a first clamping motor 32 fixed to the first clamping main seat 31. Both ends of the first clamping main seat 31 extend to the template exchange device 2 and the sewing machine 1, respectively.

The electronic automatic identification tag 51 can be an RFID tag / chip, a QR code, or a barcode. Correspondingly, in this embodiment, the sewing machine 1 is provided with an identification sensor (not shown in the figure) for identifying the above-mentioned electronic automatic identification tag (51). Of course, in other embodiments, identification sensors corresponding to the carrier seat 225 can also be provided on the first support plate 224 to identify the electronic automatic identification tag 51 of each template 5 that arrives at or leaves the carrier seat 225. The template 5 is also provided with a number of positioning posts 52, a first positioning block 53 that works in conjunction with the first clamping assembly 226, and a first clamping structure 54 and a second clamping structure 55 that cooperate with the first template clamping mechanism 3 and the second template clamping mechanism 42, respectively.

[0048] Brief description of the working principle of this utility model: This utility model has a cover plate groove 43 and a material groove 44 on the material placement platform 4. The cover plate groove 43 is used to place the cover plate 8 that needs to be sewn. The cover plate 8 can be set according to the product characteristics to correspond to the process, and can be used directly in the processing. The material groove 44 is used to place the materials that need to be sewn, such as... Figure 1 As shown, there are two large material troughs 44 on the left and right sides. Each material trough 44 is also equipped with several material compartments for storing various materials, making it more practical to use.

[0049] When the equipment starts working, the support base 225 is in an unoccupied state, such as Figure 1 As shown, the sewing machine 1, template exchange device 2, and material placement platform 4 of this utility model are arranged in an L-shape, and the working areas of the three are all at the same level. The electrical control box 9 is located above the template exchange device 2. When starting work, the operator only needs to stand in front of the material placement platform 4 to observe the working status of the above three devices at the same time. The operator can pre-install the corresponding cover plate 8 on the template 5 according to the different process requirements. The cover plate 8 is positioned and fixed by the positioning post 52 set on the template 5. Then, the corresponding material is selected from the material trough 44 and placed on the cover plate 8. Then, the operator can connect the second positioning groove 552 of the template 5 with the second positioning protrusion 4241 on the second clamping main seat 424. Then, the four-clamping cylinder is started. The fourth clamping cylinder 4261 pushes one end of the third clamping member 4263, so that the third clamping member 4263 rotates around the axis. The second clamping part 391 is inserted into the second clamping groove 551. The thrust is maintained so that the first clamping part can continuously clamp the second clamping structure 55, realizing the clamping of the template. After the template 5 is clamped, the second clamping motor 421 starts, conveying the template 5 to the support seat 225 of the template exchange device 2. Initially, the support seat 225 of any layer, the sewing machine 1 and the material placement platform 4 can be set to be level (hereinafter referred to as the working position). When the sensor 6 senses that the template 5 has entered the support seat 225 and is in place, the first clamping assembly 226 is activated. The first clamping cylinder 2261 drives the first clamping member 2262 to press down, so that the first insertion parts 226 at both ends of the first clamping member 2262 are located. 3. It can be fully inserted into the positioning through hole 531 of the second positioning protrusion 4241 to achieve the positioning and locking of the template 5; then the template lifting motor 222 is started to raise the first support plate 224 so that the second layer of the bearing seat 225 is level with the material placement platform 4. At the same time, the operator repeats the above actions to place the second template 5 and sends the second template 5 into the second layer of the bearing seat 225 through the second template clamping mechanism 42. This process is repeated until the bearing seats 225 of each layer of the template exchange device 2 all carry the template 5.

[0050] Then, the first template clamping mechanism 3 is activated, and the first clamping motor 32 drives the first clamping main seat 31 to move to one side of the bearing seat 225, so that the first positioning protrusion 361 is flush with the first positioning groove 542. Next, the second clamping cylinder 37 is activated to push out the third clamping bracket 36, so that the first positioning protrusion 361 is inserted into the first positioning groove 542. Finally, the third clamping cylinder 38 is activated to push one end of the second clamping member 39, so that the second clamping member 39 rotates around the axis. Part 391 is inserted into the first clamping groove 541, maintaining the thrust of the third clamping cylinder 38 so that the second clamping part 391 can continuously clamp the first clamping structure 54, thereby clamping the template 5. Then, the first clamping component 226 corresponding to the bearing seat 225 is activated, and the first clamping cylinder 2261 drives the first clamping member 2262 to rise, so that the first insertion part 2263 disengages from the positioning through hole 531 of the second positioning protrusion 4241, that is, the first clamping component 226... Release the template 5; finally, the first clamping motor 32 continues to start and reset, bringing the template 5 out of the carrier seat 225. When the sensor 6 senses the removal of the template 5, it will send a signal to the control box 9. The control box 9 controls the identification sensor of the sewing machine 1 to start. When the first template clamping mechanism 3 brings the template 5 to the processing area 11 of the sewing machine 1 and releases it, the identification sensor will scan the electronic automatic identification tag 51 on the template 5 and read the corresponding sewing program. The control box 9 sends the sewing program read by the electronic automatic identification tag 51 of the template 5 to the sewing machine 1. The sewing machine 1 will start sewing according to the received sewing program. After completion, the first template clamping mechanism 3 repeats the above action to bring the template 5 back to the carrier seat 225. The template exchange device 2, according to the set operation action, cooperates with the second template clamping mechanism 42 to place the template 5 that has completed the sewing task on the material placement platform 4. The operator unloads the material and then continues to repeat the above material placement action to enter the next cycle.

[0051] Of course, to achieve more efficient operation, multiple sets of carrier seats 225 can be used to achieve efficient feeding, conveying and sewing, and unloading actions based on this embodiment. For example, taking a three-layer carrier seat 225 in this embodiment for footwear processing as an example, the feeding, positioning, and conveying of the template 5 are the same as described above and will not be repeated. The specific operating logic is as follows: the three-layer carrier seats 225 are respectively referred to as the first layer carrier seat 225, the second layer carrier seat 225, and the third layer carrier seat 225. The first layer carrier seat 225 is responsible for transporting the template 5 sewn by the sewing machine 1 to the placement table; the third layer carrier seat 225 is responsible for transporting the template 5 sewn by the sewing machine 1 to the placement table; the fourth layer carrier seat 225 is responsible for transporting the template 5 sewn by the sewing machine 1 to the placement table; the fifth layer carrier seat 225 is responsible for transporting the template 5 sewn by the sewing machine 1 to the placement table; the sixth ... The second-layer support 225 is responsible for transporting the unsewn left-foot template 5 from the material placement table to the sewing machine 1 for sewing; the third-layer support 225 is responsible for transporting the unsewn right-foot template 5 from the material placement table to the sewing machine 1 for sewing; the second and third layers are used alternately, following the logic of early entry and early exit, and late entry and late exit, arranging templates 5 with longer waiting times to be sewn first; specifically, when the template 5 is first loaded, it is first sent to the second-layer support 225 (early entry) and then to the third-layer support 225 (late entry) in sequence. After the material is loaded into the third-layer support 225, the template exchange device 2 moves the second-layer support 225 down to the working position. The first template feeding mechanism 3 feeds the template 5 from the second support seat 225 into the sewing machine 1 for sewing. Simultaneously, the operator on the material placement platform 4 completes the feeding of a new template 5. The second template feeding mechanism 42 places the corresponding new template 5 onto the second support seat 225. Then, the sewing machine 1 completes the first sewing task. The template exchange device 2 is activated, moving the first support seat 225 to the work position. The first template feeding mechanism 3 places the sewn template 5 into the first support seat 225. The template exchange device 2 continues to activate, bringing the third support seat 225 to the work position. The template 5 of the third layer support seat 225 is transported to the sewing machine 1 by the first template clamping mechanism 3 for sewing. Simultaneously, the operator completes the new template 5 loading operation on the material placement platform 4. The corresponding new template 5 is placed on the third layer support seat 225 by the second template clamping mechanism 42. Then, the sewing operation on the sewing machine 1 completes the second sewing task. The template exchange device 2 is activated to move the first layer support seat 225 to the working position. The first template clamping mechanism 3 places the sewn template 5 into the first layer support seat 225. Then, the above-mentioned operation on the second layer support seat 225 is repeated.
