[0001] The present application relates to the sewing machine technical field, and particularly relates to a full-automatic sewing machine and a control method of the sewing machine. BACKGROUND

[0002] With the development of science and technology, the technical level of the sewing machine is also constantly breaking through; at the present stage, the sewing of clothes is mostly carried out by manually operating the sewing machine. Manual sewing is very challenging for the operator's technology. If the operator's technology is not up to standard, complex patterns cannot be sewn, and if the operator is slightly distracted, the pattern may be sewn incorrectly, thereby increasing the product's defective rate and affecting economic benefits.

[0003] At the present stage, in order to reduce the defective rate of the sewn products, an automatic sewing machine is mostly used to sew patterns. Although this can avoid the errors caused by manual operation, when the number of sewing is large, manual operation is still needed to push the template to the working point for sewing. Due to standardized management, the position of the pattern in each product should be consistent. If manual positioning is completely used, not only will the sewn pattern be offset, but also the work intensity of the worker will be increased. Therefore, it is necessary to improve the existing sewing machine. SUMMARY

DETAILED DESCRIPTION

[0030] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments between or between technical features can be combined to form new embodiments without conflict.

[0031] In the description of the present application, it should be noted that for orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0032] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or chronological order.

[0033] The terms "include" and "have" in the specification and claims of the present application, as well as any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] One aspect of the present application provides a full-automatic sewing machine, wherein a preferred embodiment is as followsFigure 1 , Figure 2 and Figure 3 As shown, the device includes a body 1 and a sewing head assembly 11 mounted on top of the body 1. A platform 100 is mounted on the upper end of the body 1, on which two templates 200 are placed in a front-to-back sequence. Products to be processed can be placed on the templates 200. Conveying mechanisms and lifting mechanisms that cooperate with the templates 200 are mounted on both sides of the body 1. The conveying mechanisms are used to move the templates 200 back and forth, and the lifting mechanisms are used to raise and lower the templates 200. When the device is running, the conveying mechanism moves the front template 200 to the working area, and the sewing head assembly 11 performs sewing processing on the products to be processed in the working area. After the products in the working area are processed, the lifting mechanism raises the template 200 in the working area. Subsequently, the conveying mechanism moves the rear template 200 forward, thereby achieving automatic template replacement.

[0035] It should be noted that, compared with traditional automatic sewing machines, the fully automatic sewing machine in this application can achieve seamless replacement of template 200; there is no need to wait for the operator to replace template 200, the template 200 will automatically move up after the previous template 200 is finished, and the template 200 behind will immediately move to the work area for sewing; greatly improving the processing efficiency of the product.

[0036] Specifically, such as Figures 2-4 As shown, the conveying mechanism includes a first conveyor belt 3, on which a first cylinder 31 is fixedly mounted. The first cylinder 31 can move synchronously with the first conveyor belt 3. The telescopic section of the first cylinder 31 is provided with a locking block 310. Both sides of the template 200 are provided with a first locking groove 201 and a second locking groove 202. When the template 200 needs to move, the locking block 310 can be inserted into the first locking groove 201 or the second locking groove 202 to lock and limit the template 200, ensuring that the template 200 can move synchronously with the first cylinder 31. The lifting mechanism includes a second conveyor belt 4, on which a second cylinder 41 is fixedly mounted. The second cylinder 41 can move synchronously with the second conveyor belt 4. In addition, the telescopic section of the second cylinder 41 is provided with a mounting plate 410. A traction component is mounted on the mounting plate 410, and a connecting piece 5 that cooperates with the traction component is provided on the template 200. The template 200 can be fixed by a traction component, and then the extension and retraction of the second cylinder 41 is used to control the raising and lowering of the template 200. After the template 200 is raised, it can be driven to move back and forth by the second conveyor belt 4.

[0037] In this embodiment, as Figure 6As shown, the first cylinder 31 is provided with a detachable first clamping plate 32, which has clamping effect. The first conveying belt 3 can be placed in the first clamping plate 32, and then the first clamping plate is clamped to fix the first cylinder 31 on the first conveying belt 3. When the first cylinder 31 fails, it can be quickly disassembled and repaired. Similarly, the second cylinder 41 is provided with a detachable second clamping plate 42, which can be clamped to fix the second cylinder 41 on the second conveying belt 4.

[0038] In addition, in order to further improve the fixing effect of the first clamping plate 32 and the second clamping plate 42, a concave-convex structure is arranged on the matching surface of each of the first clamping plate 32 and the second clamping plate 42 to increase the friction.

[0039] It can be understood that the clamping block 310 should be gapless when cooperating with the first clamping groove 201 or the second clamping groove 202. If there is a gap, the template 200 may shake or deviate when moving, thereby affecting the accuracy of subsequent pattern sewing. Therefore, when the extension stroke of the first cylinder 31 has an error, the position of the first cylinder 31 needs to be adjusted in time to eliminate the error.

[0040] Therefore, in some embodiments of the present application, as shown in Figure 7 The first clamping plate 32 is provided with a sliding rail 321, and the first cylinder 31 is provided with a sliding groove 311 matched with the sliding rail 321. When the extension stroke of the first cylinder 31 has an error, the effective moving range of the clamping block 310 can be adjusted by changing the position of the first cylinder 31 on the sliding rail 321.

[0041] In the embodiment, as shown in Figure 2 and Figure 4 The traction assembly includes a third cylinder 300, and the extension section of the third cylinder 300 is provided with a limiting block 301. The connecting piece 5 is provided with a limiting groove 51 for limiting the limiting block 301. When the template 200 needs to be lifted, the limiting block 301 can be inserted into the limiting groove 51, and the template 200 and the traction assembly are fixedly connected through the limiting cooperation of the limiting block 301 and the limiting groove 51, so that the template 200 can move synchronously with the traction assembly.

[0042] Further, as shown in Figure 5As shown, the limiting groove 51 is provided with an embedded part 511 and a clamping part 512 which are in communication with each other, wherein the size of the embedded part 511 is greater than that of the limiting block 301, and the size of the clamping part 512 is less than that of the limiting block 301. In this way, the limiting block 301 can quickly enter the limiting groove 51, and when the limiting block 301 enters the embedded part 511, the third cylinder 300 controls the limiting block 301 to move to the clamping part 512 for clamping, thereby realizing the fixed connection of the template 200; thereby improving the cooperation speed of the limiting block 301 and the limiting groove 51.

[0043] In this embodiment, as shown in Figure 1 and Figure 6 As shown, two fourth cylinders 400 are arranged on the side of the machine body 1 away from the head assembly 11, and the telescopic section of the fourth cylinder 400 is provided with a positioning rod 401, and the template 200 is provided with a positioning hole 203 which is inserted and matched with the positioning rod 401. When the template 200 is placed on the table plate 100, the fourth cylinder 400 controls the positioning rod 401 to extend into the positioning hole 203, so that the template 200 is at the correct placement point, avoiding the pattern stitching deviation caused by the inclination of the template 200, ensuring that the clamping block 310 is in alignment with the first clamping groove 201 or the second clamping groove 202, and preventing scratching when the clamping block 310 cooperates with the clamping groove. When the template 200 needs to be moved, the positioning rod 401 can be controlled by the fourth cylinder 400 to disengage from the positioning groove, thereby limiting the template 200.

[0044] In this embodiment, as shown in Figure 6 As shown, the lower part of the table plate 100 is provided with a first motor 500 and a second motor 600, and the first motor 500 is provided with a first shaft 501 which is used to drive the first conveying belt 3 to rotate. Similarly, the second motor 600 is provided with a second shaft 601 which is used to drive the second conveying belt 4 to rotate. The first conveying belt 3 can be controlled to rotate by the motor, thereby achieving the purpose of moving the template 200 forward and backward. The rotation direction of the first shaft 501 is changed to control the template 200 to move forward and backward. The main function of the second motor 600 is the same as that of the first motor 500, which will not be described in detail here.

[0045] Further, in order to more conveniently replace the first shaft 501 and the second shaft 601, the first shaft 501 and the second shaft 601 are segmented. Here, the first shaft 501 is taken as an example, which is designed in two sections, one of which is fixedly connected with the first motor 500, and the other of which is connected with the first conveying belt 3. The two sections are connected and fixed by a shaft coupling 800, so that the installation difficulty of the first shaft 501 can be effectively reduced, and the difficulty of installation caused by the excessive length of the first shaft 501 can be avoided.

[0046] In addition, the matching effect between the first shaft rod 501 and the first conveying belt 3 includes but is not limited to friction matching, clamping matching. In the embodiment, as shown in Figure 8 a gear 900 is arranged on the first shaft rod 501 for matching the first conveying belt 3, and the first conveying belt 3 is driven to rotate synchronously by the rotation of the gear 900. It is necessary to ensure that the friction between the gear 900 and the first conveying belt 3 is sufficient to drive the first conveying belt 3 to rotate without slipping. Of course, in order to further improve the matching strength of the gear 900 and the first conveying belt 3, an anti-skid pad can be arranged on the gear 900, or a groove matched with the gear 900 is arranged on the first conveying belt 3. The matching effect between the second shaft rod 601 and the second conveying belt 4 is the same as above.

[0047] In order to reduce the disassembly difficulty of the first motor 500 and the second motor 600, in some embodiments of the application, the table plate 100 is arranged in a plurality of matched forms, and the part of the table plate 100 above the first motor 500 and the second motor 600 can be disassembled separately. When the first motor 500 or the second motor 600 fails, only the corresponding small part of the table plate 100 needs to be removed to expose the first motor 500 or the second motor 600.

[0048] Further, as shown in Figure 6 the first motor 500 and the second motor 600 are installed with a motor plate 700, and an adjusting plate 701 is installed on the machine body 1, and the first motor 500 and the second motor 600 are installed on the adjusting plate 701 through adjusting pieces; the adjusting pieces are used to control the relative distance between the adjusting plate 701 and the motor plate 700, and when the position of the first shaft rod 501 or the second shaft rod 601 deviates, the height of the motor plate 700 can be adjusted through the adjusting pieces to adjust the first motor 500 or the second motor 600, thereby changing the position of the first shaft rod 501 or the second shaft rod 601.

[0049] In the embodiment, as shown in Figure 1 both sides of the machine body 1 are provided with a pulley block 13, and the template 200 is suitable for moving on the pulley block 13, and the friction of the table plate 100 on the template 200 can be effectively reduced through the pulley block 13. The machine body 1 is also provided with a support plate 12, which can cooperate with the table plate 100 to provide support for the template 200 in the working area. In addition, a gap is arranged between the support plate 12 and the table plate 100, and the head assembly 11 is located above the gap, and the machine body 1 is provided with a driving assembly for controlling the movement of the head assembly 11. When the machine works, the driving assembly controls the head assembly 11 to move and sew patterns.

[0050] Another aspect of the present application provides a control method of a sewing machine, which can be applied to the fully automatic sewing machine described above; a preferred embodiment thereof includes a controller and a plurality of sensors installed on the machine body 1, which are used to monitor the position of the template 200 and transmit signals to the controller to control the operation of the lifting mechanism and the conveying mechanism. The control method includes the following steps: S1: Place two templates 200 in front of and behind the template 200, and control the first cylinder 31 to extend the clamping block 310 into the second clamping groove 202 of the front template 200, then drive the first conveying belt 3 to move the corresponding template 200 forward, so that the template 200 reaches the designated sewing point.

[0051] S2: After the front template 200 is sewn, the limiting block 301 is lowered and inserted into the embedding part 511, the second cylinder 41 controls the limiting block 301 to move and make the limiting block 301 move to the clamping part 512 for clamping, then the second cylinder 41 drives the template 200 to move upwards and away from the table plate 100, and finally the second conveying belt 4 drives the corresponding template 200 to move backward to provide space for the rear template 200 to move.

[0052] S3: After the front template 200 is lifted, the first conveying belt 3 drives the first cylinder 31 to move backward, so that the clamping block 310 extends into the first clamping groove 201 of the rear template 200, and the first conveying belt 3 drives the first cylinder 31 to move the rear template 200 to the front, thereby realizing the automatic replacement of the template 200.

[0053] S4: The second cylinder 41 is retracted, and the template 200 is lowered to the rear area, then the limiting block 301 is disengaged from the limiting groove 51 and rises to the initial position.

[0054] The working principle of the control method of the sewing machine is that the sensor detects the position of the template 200 and transmits signals to the controller, and the controller controls the conveying mechanism and the lifting mechanism to work. When the templates 200 are placed in front of and behind the table plate 100, the first motor 500 drives the first conveying belt 3 to rotate and make the clamping block 310 engage with the second clamping groove 202 on the front template 200, then the conveying belt continues to rotate and drives the template 200 to move to the working area for pattern sewing. After the product on the front template 200 is drawn, the controller controls the second cylinder 41 to retract, and the limiting block 301 engages with the limiting groove 51, then the controller controls the second cylinder 41 to extend and drives the front template 200 to move upwards. Then the first conveying belt 3 drives the first cylinder 31 to move backward and makes the clamping block 310 engage with the first clamping groove 201 of the rear template 200, and the first cylinder 31 drives the rear template 200 to move forward. At the same time, the second cylinder 41 drives the front template 200 to move backward, so that the front and rear templates 200 are exchanged, and the operator can replace the processed product with the unprocessed product.

[0055] It can be understood that the device automatically cycles the above steps, and the worker only needs to replace the processed product with the unprocessed product. Not only the processing efficiency of the product is improved, but also the labor intensity of the worker is reduced.

[0056] Further, the first air cylinder 31 located on both sides of the machine body 1 works with a delay. One side of the first air cylinder 31 works first for a certain time to limit the position of the template 200, and the other side works to ensure clamping and positioning purposes, further improving the positioning accuracy of the template 200 and ensuring that the pressure on both sides of the template 200 is equal.

[0057] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
