Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and in particular to an automatic sewing machine fabric loading device. Background Technology

[0002] Currently, automatic sewing machines perform fabric feeding and sewing sequentially. The machine stops during fabric feeding, resulting in low utilization; and it cannot feed fabric during sewing, leading to low efficiency. Furthermore, the manual fabric feeding process is tedious and labor-intensive. Working for extended periods can easily lead to low alignment rates and increased rework rates. This process is also heavily influenced by human experience, making it difficult to guarantee production efficiency and resulting in inconsistent product quality.

[0003] For example, the prior art discloses an automatic hem ribbing sewing machine, application number CN202221773849.9, which includes a box-type machine body and a control system. A sewing machine is fixed on the table of the box-type machine body. The feature is that it also includes a feeding module, a picking module grabs the top layer of ribbing from the feeding module and places the ribbing on the table, a folding module aligns the fabric edge and then clamps one end of the ribbing and folds it to the other end and folds the edge at the sewing joint, a presser foot module moves the folded and edged ribbing towards the head of the sewing machine, the sewing machine performs the sewing, and a receiving module collects the sewn ribbing.

[0004] While the above solution can achieve automated fabric loading through the cooperation of components such as the feeding module, the picking module, the folding module, and the presser foot module, the device has a complex structure and high cost. Furthermore, the feeding module and the picking module require the participation of multiple components when cooperating to pick up and load the fabric, and the stability of the vacuum suction cup is required. This undoubtedly affects the efficiency and maintenance costs during long-term use. Summary of the Invention

[0005] In view of the problems mentioned in the background art regarding the complex structure and high cost of the fabric loading component of the existing sewing machine, this application provides an automatic sewing machine fabric loading device. The device adopts the coordinated work of the fabric loading module and the motion module, so that the automatic sewing machine can start loading the material while sewing, keeping the equipment in a sewing state. The entire device has a simple structure, low cost, can be used to load the material with the automatic sewing machine, and can also work independently. It is suitable for external use on various sewing machines and has good practical application results.

[0006] To achieve the above objectives, the present invention discloses an automatic sewing machine fabric loading device, comprising a device body disposed on the sewing machine, the device body comprising:

[0007] The upper fabric module clamps two layers of fabric and aligns the fabric edges;

[0008] The motion module drives the fabric loading module to transfer the aligned fabric.

[0009] The device body includes a connecting plate assembly, on which the fabric feeding module is mounted. The motion module adjusts the position of the connecting plate assembly to control the fabric feeding module's fabric transfer. The device body is mounted on an automatic sewing machine via the connecting plate assembly, allowing for external mounting without requiring modification to the existing automatic sewing machine; only installation space is needed. The fabric feeding module clamps the double-layered fabric, while the motion module controls the position and clamping state of the fabric feeding module, ensuring it moves to the correct position for accurate fabric clamping.

[0010] Preferably, the connecting plate assembly includes a sliding connecting plate and a module mounting plate. The motion module includes front and rear motors, and a transmission belt connects the front and rear motors to the sliding connecting plate. Upper and lower cylinders are installed between the sliding connecting plate and the module mounting plate. The front and rear motors control the forward and backward movement of the sliding connecting plate via the transmission belt, while the sliding connecting plate is connected to the module mounting plate via the upper and lower cylinders, thereby controlling the height of the module mounting plate. This, in conjunction with the front and rear motors, ensures that the modules on the module mounting plate reach the correct positions for operation.

[0011] Preferably, the upper fabric module includes a presser foot alignment module, which includes a presser foot clamping cylinder fixed to the module mounting plate. A presser foot pressing fabric connecting plate is located at the bottom of the presser foot clamping cylinder and is slidably connected to the module mounting plate. An upper presser foot pressing plate is located at the bottom of the connecting plate, and a lower presser foot pressing plate is located at the bottom of the module mounting plate corresponding to the upper plate. The presser foot alignment module is used to press the front end of the fabric and ensure alignment at the seams. The presser foot clamping cylinder controls the upper presser foot pressing plate to move up and down, sequentially pressing the fabric.

[0012] Furthermore, the module mounting plate is equipped with a movable plate, which is located on the front and rear sides of the module mounting plate along its thickness direction, respectively, along with the upper and lower presser foot and fabric pressing plate. A fabric pressing area is formed between the upper and lower presser foot and fabric pressing plates. A first fabric rod and a second fabric rod extending along the width direction of the module mounting plate are arranged on the side of the fabric pressing area. The tail of the first fabric rod is fixedly connected to the module mounting plate, and the tail of the second fabric rod is connected to the movable plate. The second fabric rod can swing up and down with the movable plate. The first and second fabric rods are used to separate the upper and lower layers of fabric. Because the movable plate can move up and down, a gap is maintained between the upper and lower fabrics, allowing the fabrics to be sequentially transferred to the seam-fitting module of the automatic sewing machine for proper seam fitting.

[0013] Preferably, the module mounting plate is also equipped with a bob-aligning fabric clamping cylinder. A bob-aligning fabric clamping upper plate is located at the bottom of the cylinder, and this upper plate is slidably connected to the module mounting plate. A bob-aligning fabric clamping lower plate is located at the bottom of the module mounting plate opposite the upper plate. A downwardly extending guide rod is threaded through the lower plate of the cylinder, and a spring is fitted onto the guide rod. The bob-aligning fabric clamping cylinder controls the height of the upper plate, thereby achieving the pressing and separation of the upper and lower fabrics. When the fabric loading module moves to the target position, the sewing machine presser foot presses down, and the upper and lower bob position detection point components clamp the fabric, completing the fabric loading action at this point.

[0014] Preferably, the fabric loading module further includes an intermediate clamp fabric loading module, which includes an intermediate fabric clamping cylinder mounted on the module mounting plate. An intermediate fabric clamping connecting plate is connected to the bottom of the intermediate fabric clamping cylinder and is slidably connected to the module mounting plate. An upper intermediate fabric clamping plate and a lower intermediate fabric clamping plate are spaced apart on the intermediate fabric clamping connecting plate. The intermediate clamp fabric loading module ensures the compression of the middle section of the fabric, corresponding to the intermediate clamping configuration of the automatic sewing machine. The upper and lower intermediate fabric clamping plates achieve the separation and compression of the upper and lower fabrics, enabling synchronous transfer with the fabric clamping point at the boning point.

[0015] Furthermore, the module mounting plate is also provided with a left and a right intermediate fabric clamping partition, with the left partition overlapping the bottom of the upper intermediate fabric clamping plate. The left and right intermediate fabric clamping partitions are fixedly mounted on the module mounting plate at the same height. When the intermediate fabric clamping cylinder extends downwards, the upper intermediate fabric clamping plate adheres to the left intermediate fabric clamping partition to clamp the upper layer of fabric, while the lower intermediate fabric clamping plate adheres to the forward-extending flange at the bottom of the module mounting plate when the intermediate fabric clamping cylinder extends downwards to press the lower layer of fabric.

[0016] Preferably, the upper fabric module further includes a correction redundancy module, which includes an adjustment plate movably mounted on the module mounting plate and can slide along the width direction of the module mounting plate.

[0017] Furthermore, the adjustment plate is provided with an extension cylinder, which includes a movable end extending along the width direction of the module mounting plate. A lower clamping plate fixing block is provided on the movable end, and an extension movable plate is provided on the back of the lower clamping plate fixing block. The extension movable plate is laterally slidably connected to the adjustment plate.

[0018] The correction redundancy module is used in conjunction with the presser foot to clamp and fix the tail end of the fabric to the bone module, while the adjustment plate can be adjusted laterally. This allows the device to adapt to fabrics of different lengths, improving the feeding efficiency of fabrics of various specifications. Not only can the extended cylinder be adjusted laterally, but the adjustment plate can also be changed laterally.

[0019] Furthermore, the extended movable plate is equipped with a correction-positioning clamping cylinder, and a movable block is connected to the correction-positioning clamping cylinder. An upper garment piece clamping plate and a lower garment piece clamping plate are arranged parallel to each other on the movable block. An upper garment piece lower clamping plate and a lower garment piece lower clamping plate are arranged on the lower clamping plate fixing block. When the correction-positioning clamping cylinder extends, the upper garment piece clamping plate abuts against the lower garment piece clamping plate, and the lower garment piece clamping plate abuts against the lower garment piece clamping plate. The height of the upper and lower garment piece clamping plates is controlled by the correction-positioning clamping cylinder to ensure that they can respectively cooperate with the lower garment piece clamping plates to clamp the upper and lower layers of fabric. The movable block is used to install the parallel-spaced upper and lower garment piece clamping plates.

[0020] Therefore, the present invention has the following beneficial effects:

[0021] (1) The fabric loading module and the motion module work together to allow the automatic sewing machine to start feeding materials while sewing, so that the equipment is always in the sewing state. The whole device has a simple structure and low cost. It can be used to feed materials with the automatic sewing machine and can also work independently. It is suitable for external use on various sewing machines and has good practical application effect.

[0022] (2) By setting up the correction redundancy module, the fabric can be adapted to various specifications to ensure efficient fabric feeding;

[0023] (3) The device body can be directly assembled and connected with various models of stitching machines, which has good versatility and can meet the needs of the existing market. Attached Figure Description

[0075] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0076] Example 1

[0077] like Figure 1 As shown, an automatic sewing machine fabric loading device includes a device body 200 disposed on the sewing machine 100; as Figure 2 , 3 As shown, the device body 200 includes: a fabric loading module for clamping two layers of fabric and aligning the fabric edges; and a motion module for driving the fabric loading module to transfer the aligned fabric. The device body 200 includes a connecting plate assembly, the fabric loading module is mounted on the connecting plate assembly, and the motion module adjusts the position of the connecting plate assembly to control the fabric loading module's fabric transfer. The device body 200 is mounted on the automatic sewing machine 100 via the connecting plate assembly, allowing for external mounting without requiring modification of the original automatic sewing machine; only installation space is needed. The fabric loading module clamps the double-layered fabric, while the motion module controls the position and clamping state of the fabric loading module, ensuring that the fabric loading module moves to the correct position for accurate fabric clamping.

[0078] The connecting plate assembly includes a sliding connecting plate 2 and a module mounting plate 4. The motion module includes front and rear motors 1, and a transmission belt 8 connects the front and rear motors 1 to the sliding connecting plate 2. Upper and lower cylinders 3 are installed between the sliding connecting plate 2 and the module mounting plate 4. The front and rear motors 1 control the forward and backward movement of the sliding connecting plate 2 via the transmission belt 8, while the sliding connecting plate 2 is connected to the module mounting plate 4 via the upper and lower cylinders 3, thereby controlling the height of the module mounting plate 4. This, in conjunction with the front and rear motors 1, ensures that the modules on the module mounting plate 4 reach the correct positions for operation. In this embodiment, the front and rear motors 1 drive the sliding connecting plate 2 to move forward and backward via the belt 8, thus causing the entire lower mechanism to move forward and backward. The upper and lower cylinders 3 are fixed below the sliding connecting plate 2, driving the module mounting plate 4 to move up and down. The automatic sewing machine is equipped with two sensors, used to detect whether the upper fabric module has moved to the fabric clamping and transfer position and the retraction position, respectively.

[0079] like Figure 4 , 5 As shown, the upper fabric module includes a presser foot alignment module 5, which includes a presser foot clamping cylinder 501 fixed on the module mounting plate 4. The presser foot clamping cylinder 501 has a presser foot pressing fabric connecting plate 502 at its bottom, and the presser foot pressing fabric connecting plate 502 is slidably connected to the module mounting plate 4. The presser foot pressing fabric connecting plate 502 has an upper presser foot pressing fabric plate 503 at its bottom, and the module mounting plate 4 has a lower presser foot pressing fabric plate 504 at its bottom corresponding to the upper presser foot pressing fabric plate 503. The module mounting plate 4 is provided with a movable plate 507. The movable plate 507 and the upper presser foot presser cloth plate 503 are respectively located on the front and rear sides of the module mounting plate 4 in the thickness direction. The area between the upper presser foot presser cloth plate 503 and the lower presser foot presser cloth plate 504 is the presser cloth area. A first cloth rod 509 and a second cloth rod 506 extending along the width direction of the module mounting plate 4 are provided on the side of the presser cloth area. The tail of the first cloth rod 509 is fixedly connected to the module mounting plate 4, and the tail of the second cloth rod 506 is connected to the movable plate 507. The second cloth rod 506 can swing up and down with the movable plate 507. The movable plate 507 is connected to the module mounting plate 4 through a torsion spring 508. The module mounting plate 4 is also provided with a bone clamping cylinder 510. The bottom of the bone clamping cylinder 510 is provided with a bone clamping upper plate 511, which is slidably connected to the module mounting plate 4. The bottom of the module mounting plate 4 is provided with a bone clamping lower plate 513 corresponding to the bone clamping upper plate 511. A downwardly extending guide rod 514 is provided through the bone clamping cylinder lower plate 513. The guide rod 514 is connected to the guide fixing plate 512 and fixed on the module mounting plate 4. A spring 515 is sleeved on the guide rod 514.

[0080] The presser foot alignment module 5 is used to press the front end of the fabric and ensure alignment at the seam. The presser foot clamping cylinder 501 controls the presser foot upper plate 503 to move up and down, pressing sequentially. The first fabric rod 509 and the second fabric rod 506 are used to separate the upper and lower layers of fabric. Because the movable plate 507 can move up and down, a gap is maintained between the upper and lower fabrics, allowing the fabrics to be sequentially transferred to the presser foot alignment module 5 of the automatic sewing machine for proper alignment. The alignment clamping cylinder 510 controls the height of the alignment clamping upper plate 511, thereby achieving the pressing and separation of the upper and lower fabrics. When the upper fabric module moves to the target position, the sewing machine presser foot presses down, and the upper and lower rib detection point components clamp the fabric, completing the upper fabric loading action.

[0081] In this embodiment, the automatic sewing machine's fabric feeding process involves feeding two pieces of fabric. The upper and lower fabrics are aligned and placed between the upper and lower presser foot plates 503 and 504. The upper fabric is then placed above the first fabric bar 509, and the lower fabric below it. The presser foot clamping cylinder 501 is then activated, causing the upper and lower presser foot plates 503 and 504 to press the two fabrics firmly, allowing the fabric to enter the sewing machine's presser feet. The first fabric bar 509 then separates the two fabrics. Next, the upper fabric is placed below the upper rib clamping plate 511, and the lower fabric below the lower rib clamping plate 513. The rib clamping cylinder 510 is activated to separate and press the fabrics together. This creates a gap of approximately 3-5 mm between the two fabrics at the rib joint, facilitating alignment with the sewing machine's rib joint 101. Once the fabric feeding mechanism reaches the target position, the sewing machine presser foot presses down, and the stitching machine clamps the fabric at the upper and lower bone detection point components of bone position 101, completing the fabric feeding action at this point.

[0082] like Figure 6 , 7 As shown, the upper fabric module also includes an intermediate clamp upper fabric module 6. The intermediate clamp upper fabric module 6 includes an intermediate fabric clamping cylinder 61 disposed on the module mounting plate 4. An intermediate fabric clamping connecting plate 62 is connected to the bottom of the intermediate fabric clamping cylinder 61, and the intermediate fabric clamping connecting plate 62 is slidably connected to the module mounting plate 4. An intermediate fabric clamping upper plate 63 and an intermediate fabric clamping lower plate 64 are disposed at intervals on the intermediate fabric clamping connecting plate 62. An intermediate fabric clamping left partition 65 and an intermediate fabric clamping right partition 66 are also disposed on the module mounting plate 4. The intermediate fabric clamping left partition 65 is stacked at the bottom of the intermediate fabric clamping upper plate 63.

[0083] The intermediate clamp upper fabric module 6 is used to ensure the compression of the middle section of the fabric. Corresponding to the intermediate clamp setting of the automatic sewing machine, the upper intermediate clamping plate 63 and the lower intermediate clamping plate 64 realize the separation and compression of the upper and lower fabrics, and achieve synchronous transmission with the fabric clamping point of the bobbin. The left intermediate clamping partition 65 and the right intermediate clamping partition 66 are fixedly installed at the same height on the module mounting plate 4. When the intermediate clamping cylinder 61 extends downward, the upper intermediate clamping plate 63 fits against the left intermediate clamping partition 65 to complete the clamping of the upper fabric, while the lower intermediate clamping plate 64 fits against the forward-extending flange at the bottom of the module mounting plate 4 when the intermediate clamping cylinder 61 extends downward to compress the lower fabric.

[0084] In this embodiment, the operation of the intermediate clamp fabric loading module 6 is as follows: the upper layer of fabric is placed between the upper plate 63 and the left partition 65 of the intermediate clamp fabric, and above the right partition 66 of the intermediate clamp fabric; the lower layer of fabric is placed below the lower plate 64 and the right partition 66 of the intermediate clamp fabric; the intermediate clamp fabric cylinder 61 is driven to separate and press the upper and lower layers of fabric, thereby creating a 5mm gap between the upper and lower layers of fabric to allow the intermediate clamp to enter. When the fabric loading mechanism moves to the target position, the intermediate clamp presses down to complete the clamping and transfer, and then the intermediate clamp fabric cylinder 61 resets and releases the fabric.

[0085] like Figure 8 , 9 As shown, the upper fabric module also includes a correction redundancy module 7. The correction redundancy module 7 includes an adjustment plate 701 movably mounted on the module mounting plate 4. The adjustment plate 701 can slide along the width direction of the module mounting plate 4. An extension cylinder 710 is provided on the adjustment plate 701. The extension cylinder 710 includes a movable end extending along the width direction of the module mounting plate 4. A lower clamping plate fixing block 707 is provided on the movable end. An extension movable plate 711 is provided on the back of the lower clamping plate fixing block 707. The extension movable plate 711 is laterally slidably connected to the adjustment plate 701. The extended movable plate 711 is equipped with a correction redundancy clamping cylinder 703, and a movable block 704 is connected to the correction redundancy clamping cylinder 703. The movable block 704 is equipped with an upper garment piece upper clamping plate 705 and a lower garment piece upper clamping plate 706 arranged in parallel on the movable block 704. The lower clamping plate fixing block 707 is equipped with an upper garment piece lower clamping plate 708 and a lower garment piece lower clamping plate 709. When the correction redundancy clamping cylinder 703 extends, the upper garment piece upper clamping plate 705 abuts against the upper garment piece lower clamping plate 708, and the lower garment piece upper clamping plate 706 abuts against the lower garment piece lower clamping plate 709.

[0086] The correction redundancy module 7 is used in conjunction with the presser foot to press and fix the fabric tail end of the boning module 5, while the adjusting plate 701 can be adjusted laterally, allowing the device body 200 to adapt to fabrics of different lengths and improving the fabric loading efficiency of various specifications. Not only can the extension cylinder 710 be adjusted laterally, but the adjusting plate 701 can also be changed laterally. The upper garment plate 705 and the lower garment plate 706 are height-controlled by the correction redundancy clamping cylinder 703, ensuring that they can respectively cooperate with the lower garment plate 708 and the lower garment plate 709 to clamp the upper and lower layers of fabric. The movable block 704 is used to install the upper garment plate 705 and the lower garment plate 706, which are arranged in parallel intervals. In this embodiment, the operation of the redundant fabric feeding module 7 is as follows: the upper garment piece is placed between the upper garment piece upper clamping plate 705 and the lower garment piece lower clamping plate 708, and the lower garment piece is placed between the lower garment piece upper clamping plate 706 and the lower garment piece lower clamping plate 709. Then, the redundant fabric feeding cylinder 703 is pressed down to clamp the upper and lower garment pieces, forming a 5mm gap. When the feeding mechanism moves to the target position, which is the clamping jaw of the redundant fabric feeding clamp, the extension cylinder 710 extends to feed the fabric into the clamp. After the clamping action is completed, the redundant fabric feeding cylinder 703 is released and the extension cylinder 710 is retracted. By changing the left and right positions of the redundant fabric feeding module 7, it can adapt to garment pieces of different lengths. The adjustment does not require the replacement of any parts or tools. It can be completed by manually tightening the two screws 702 on the adjustment plate.

[0087] In this embodiment, the fabric loading module is initially positioned at the manual feeding position. After feeding and clamping, the upper and lower cylinders 3 descend, and the front and rear motors 1 drive the entire fabric loading module to the fabric clamping and transfer position. Once the presser foot presses down on the fabric, and the fabric pieces at the rib detection point, intermediate clamp, and redundant correction point are clamped and transferred, the front and rear motors 1 drive the entire mechanism to the withdrawal position. After the fabric is completely detached, the upper and lower cylinders 3 rise, and the front and rear motors 1 return the entire mechanism to the manual feeding position, completing one fabric loading action. It is worth noting that in this embodiment, the presser foot upper fabric plate 503 and presser foot lower fabric plate 504 are designed to be thin and compact, ensuring that two layers of fabric can be clamped and passed through the presser foot position of the automatic sewing machine. A certain gap between the upper and lower fabrics must be created at the rib alignment position, intermediate clamp position, and redundant correction position to ensure smooth transfer. The transfer at the rib alignment position requires the use of the rib alignment lower fabric clamping plate 513 to press the lower layer of fabric to the bottom to accommodate the automatic sewing machine's transfer of the rib module structure. Most importantly, the entire process of transferring the upper and lower fabrics by separating and pressing them can be completed while the automatic sewing machine is running, improving efficiency through independent operation.
