Description

Technical Field

[0001] This invention relates to the field of template sewing machine technology, and more specifically, to a template sewing machine and its control method that avoids needle puncturing the template. Background Technology

[0002] Traditionally, garment manufacturers often use automatic template sewing machines for continuous stitching of medium to large batches of garment pieces. When using an automatic template sewing machine, the fabric to be processed is first sandwiched between the upper and lower layers of a garment template. The template sewing machine then automatically sews and processes the fabric sandwiched within the template according to the pre-set stitching path, thus achieving fully automated garment sewing, promoting the streamlining of garment template processing, and significantly improving production efficiency.

[0003] Currently, when template machines perform quilting operations, most templates use two templates to sandwich the fabric for quilting. To ensure the fabric is pressed firmly by the template and to ensure the sewing stitches are secure, the slots on the template are generally quite small. However, during use, if the operator does not place the template correctly, the needle may pierce the template, causing it to break. This results in the scrapping of the quilted fabric and damage to the template. Furthermore, the actual quilting trajectory may not match the trajectory required by the template, causing the needle to pierce the template, damaging both the fabric and the template, resulting in unnecessary waste.

[0004] Therefore, how to solve the problem of the needle piercing the template due to the template not being placed in place is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] The core of this invention is to provide a template sewing machine that prevents the needle from piercing the template 5, thus avoiding needle piercing the template 5 when it is not in place. Another core aspect of this invention is to provide a control method for a template sewing machine that includes the aforementioned needle-avoidance mechanism, effectively improving the sewing performance of the template sewing machine and reducing its operational difficulty.

[0047] Please refer to Figure 1A template sewing machine for preventing needle punctures on the template includes a worktable 1, a sewing machine head 2, a feeding device 3, an image acquisition device 4, and a control device. Specifically, the sewing machine head 2, the feeding device 3, and the image acquisition device 4 are all signal-connected to the control device, which controls the operation of these components. The sewing machine head 2 and the feeding device 3 are both located on the worktable 1. The feeding device 3 moves the quilting template 5, and the sewing machine head 2 sews the fabric clamped to the quilting template 5. The image acquisition device 4 is connected to the sewing machine head 2 and is used to acquire images of the quilting template 5 on the worktable 1 in real time. The acquired image information is sent to the control device, which controls the operating parameters of the feeding device 3 to prevent the needle from puncturing the quilting template 5.

[0048] Please refer to Figure 3 The quilting template 5 is generally composed of two templates. A groove is cut at the position where quilting is needed to reserve space for the quilting. The quilting piece to be sewn is placed between the two templates. The two templates serve to clamp and fix the quilting piece.

[0049] The template sewing machine designed in the above manner avoids needle puncturing the template by comparing the actual image information of the quilting template 5 with the image stored in the control device, thereby controlling the template sewing machine to adjust the feeding operation parameters and preventing the needle from puncturing the quilting template 5.

[0050] In the above embodiment, the feeding device 3 includes a driving mechanism 31 for driving the quilting template 5 to move along two mutually perpendicular directions on the top surface of the workbench 1, and also includes a pressing component 32 for pressing the quilting template 5.

[0051] It should be noted that the clamping assembly 32 is controlled by the control device to clamp the quilting template 5, and the drive mechanism 31 is controlled to move the quilting template 5 along two mutually perpendicular directions on the top surface of the worktable 1. The specific movement of the quilting template 5 is adjusted according to the difference between the quilting groove of the quilting template 5 and the required quilting groove, by adjusting the operating parameters of the drive mechanism 31.

[0052] In the above embodiment, the drive mechanism 31 includes a drive module disposed on the top surface of the worktable 1 and a lead screw assembly disposed on the bottom surface of the worktable 1. The drive module extends along the X direction of the worktable 1, and the lead screw assembly extends along the Y direction of the worktable 1. The lead screw assembly is used to drive the drive module to move along the Y direction. The clamping assembly 32 is connected to the drive module, and the drive module is used to drive the clamping assembly 32 to move along the X direction. The clamping assembly 32, the drive module, and the lead screw assembly are all signal connected to the control device.

[0053] Understandably, after the control clamping component 32 clamps the quilting template 5, the control device adjusts the operating parameters of the drive module and the lead screw assembly according to the image information of the quilting template 5 collected by the image acquisition device 4, and at the same time controls the sewing machine head 2 to run so that the needle can sew the fabric on the quilting template 5, while ensuring that the needle will not prick the quilting template 5.

[0054] Please refer to Figure 2 The clamping assembly 32 includes a connecting plate, a crossbeam 321, and a cylinder 322. The connecting plate is connected to the drive module, the crossbeam 321 is connected to the connecting plate and extends along the X direction, the crossbeam 321 has a C-shaped cross section along the Z direction of the worktable 1, the cylinder 322 is located at the inner top of the crossbeam 321, the cylinder 322 is connected to the control device, the output end of the cylinder 322 moves telescopically along the Z direction, and the output end of the cylinder 322 is connected to the pressure block 323.

[0055] It should be noted that during use, the operator first places the quilting template 5 into the crossbeam 321, then starts the equipment. The control device first controls the cylinder 322 to start, causing the cylinder 322 to drive the pressure block 323 to move closer to the quilting template 5 to press the quilting template 5. After the pressure block 323 presses the quilting template 5, the image acquisition device 4 acquires an image of the quilting template 5 on the workbench 1 and sends the acquired image information to the control device. The control device adjusts the operating parameters of the drive module and the lead screw assembly based on the current image information so that the needle can stably sew in the quilting groove of the quilting template 5 without pricking the quilting template 5.

[0056] The clamping of the quilting template 5 can be achieved by setting the operating parameters of the cylinder 322 in the control device, or by setting a sensor to determine the clamping status of the pressure block 323 on the quilting template 5. There are no restrictions on this, as long as the above-mentioned technical effects can be achieved.

[0057] In the above case, there are multiple cylinders 322, and the multiple cylinders 322 are evenly arranged in the crossbeam 321 along the X direction.

[0058] It is understood that in this embodiment, the quilting template 5 is pressed by setting a cylinder 322. However, in practical applications, other methods can be used to replace the cylinder 322, and there are no restrictions on this.

[0059] In the above embodiments, the control device includes a control unit for receiving, judging, processing image information and sending instructions, an alarm unit for alarm prompting, and a display unit for displaying operating parameters.

[0060] It should be noted that the control unit receives image information acquired by the image acquisition device 4 and judges the acquired image to determine whether the current image is consistent with the image pre-stored by the control unit. If they are consistent, the control unit calculates the distance between the current quilting groove of the quilting template 5 and the pre-stored quilting groove, adjusts the operating parameters of the feeding device 3, and displays the operating parameters of the feeding device 3 through the display unit. When the control unit determines that the current image is inconsistent with the image pre-stored by the control unit, the control alarm unit is activated to prompt the staff to replace the quilting template 5.

[0061] Please refer to Figure 4 and Figure 5 A control method for preventing needle punctures on the template, applied to the aforementioned template sewing machine for preventing needle punctures on the template, the control method includes:

[0062] Step S1: Acquire image information of the working file using the image acquisition device 4 and send it to the control device;

[0063] Step S2: The control device determines whether the received image information is consistent with the pre-stored image information;

[0064] Step S3: If they match, the control device calculates the difference between the quilting groove of the quilting template 5 in the work document and the required quilting groove, and adjusts the operating parameters of the feeding device 3 according to the calculated parameters, and then controls the template sewing machine to start and carry out sewing work.

[0065] Step S4: If there is a discrepancy, the control device will issue an alarm and stop the template sewing machine.

[0066] When the work document is placed on the worktable 1 of the template sewing machine, the image acquisition device 4 acquires an image of the work document and sends the image to the control device of the template sewing machine. The control device determines whether the received image information is consistent with the pre-stored image information. If they are consistent, the control device calculates the difference between the quilting groove of the quilting template 5 of the work document and the required quilting groove. Based on the calculated parameters, it adjusts the operating parameters of the feeding device 3 and then controls the template sewing machine to start sewing. In other words, if it is determined that the acquired image information matches the image information currently stored in the equipment, it calculates the difference between the acquired quilting groove and the existing quilting groove, feeds the difference back to the control device, and then the control device adjusts the operating parameters of the feeding device 3 to start the template sewing machine. If they are inconsistent, the control device issues an alarm and stops the template sewing machine. In other words, if the control device determines that the acquired image information does not match the image information currently stored in the equipment, the control device issues an alarm and prevents the template sewing machine from starting.

[0067] The control method described above, designed to prevent needles from puncturing the template, compares the actual image information of the quilting template 5 with the image stored in the control device. This controls the template sewing machine to adjust its feeding parameters, preventing the needle from puncturing the quilting template 5. When the quilting template 5 is misplaced or the file is incorrect, the control device alarms and restricts the start of the template sewing machine, protecting both the quilting template 5 and the template sewing machine, and avoiding unnecessary waste.

[0068] In the above embodiments, before acquiring image information of the working file by the image acquisition device 4, the method further includes:

[0069] The cylinder 322 of the control feeding device 3 is raised;

[0070] After the work document is placed under the cylinder 322, control the cylinder 322 to press down to clamp the work document.

[0071] It should be noted that before acquiring the image information of the work document, the cylinder 322 is first raised by the control device to provide space for placing the work document. Then, the work document is placed in the crossbeam 321 of the feeding device 3, and the cylinder 322 is started to press the work document through the pressure block 323.

[0072] In the above situations, after the control device issues an alarm, it includes:

[0073] Adjust working documents;

[0074] The image acquisition device 4 acquires the image information of the working file and sends it to the control device.

[0075] Understandably, when the control device issues an alarm, the staff will replace the working documents.

[0076] Furthermore, after the control device issues an alarm but before adjusting the working file, it also includes:

[0077] The cylinder 322 of the control feeding device 3 releases the working file.

[0078] It should be noted that when the control device issues an alarm, cylinder 322 should be lifted first to release the working file before replacement.

[0079] In summary, the template sewing machine provided by this invention, which avoids needle puncturing the template, can solve the problems of needle puncturing the template due to improper placement of the quilting template 5 and malfunctions caused by the mismatch between the quilting template 5 and the actual pattern. It effectively improves the sewing performance of the equipment and reduces the difficulty of operation.
