[0002] The existing sewing process and production methods all use a manual operation mode. After the backpack webbing is cut to the required length, it is folded by hand, placed into the clamping jig, and then the cut webbing is embedded in the folded triangular piece. The material is then pressed and fixed by hand before being sewn into a finished product by a sewing machine.
[0003] Traditional manual operation has the following drawbacks:

A webbing rear end pressure plate is provided at the bottom of the triangular piece folding tail wing seat, and a cylinder is connected to the end of the webbing rear end pressure plate.
[0030] The triangular piece picking and pressing mechanism retrieves a triangular piece from the hopper using vacuum suction. The picking mechanism then rises and moves to the unloading position via a linear module slider. It then descends to release the triangular piece before rising back to the picking position (before releasing the triangular piece, the vacuum suction under the folding and flipping platform holds it in place, allowing the picking suction cup to break the vacuum and release it). The webbing traction clamp holds the webbing at the waiting station. When the triangular piece picking mechanism returns to its original position, the webbing traction mechanism begins to pull the webbing to the unloading position. The webbing clamp then descends, and the rear end pressing mechanism presses down to fix the webbing. The webbing clamp then opens and retracts, exiting the unloading position before rising back to its original position. At this point, the front end pressing mechanism extends... The front end of the webbing is pressed down to fix it. Then, the triangular piece folding and flipping mechanism folds and flips the triangular piece in half. The left and right ends of the folded triangular piece overlap neatly and symmetrically. Then, the triangular piece webbing finished product pressing mechanism rises, extends, and presses down to fix the corners of the triangular piece. Then, the tail wing pressing mechanism opens, retracts, and closes to release the tail wing and fix it. Then, it flips back to its original position. At this time, the electronic sensor outputs a signal to the sewing machine through the flipping back position. The sewing machine's X-axis slides out sideways, the aircraft frame presses down, and the webbing is pressed down. Then, the electronic sensor detects that the pressing action is completed. The front and rear end pressing mechanisms of the webbing and the triangular piece webbing finished product pressing mechanism return to their original positions. Then, the side slides out and returns to its original position for sewing processing. After processing is completed, it returns to the waiting position to wait.
[0031] Preferably, the triangular piece folding and flipping mechanism includes a flipping mechanism base plate, a triangular piece flipping front support plate is provided above the flipping mechanism base plate, and a flipping plate buffer column is provided between the flipping mechanism base plate and the triangular piece flipping front support plate;
[0032] A triangular piece flipping rear rod is provided on the triangular piece flipping front support plate, and a triangular piece vacuum suction sealing plate is provided on the triangular piece flipping front support plate;
[0033] A tail wing folding piece is provided on the support plate before the triangular piece flips, and a cylinder is provided on the tail wing folding piece;
[0034] Before the triangular piece flips, the support plate is equipped with two triangular piece tail folding wing fixing plates and one triangular piece tail end pressing fixing plate, and the triangular piece tail end pressing fixing plate is equipped with a triangular piece tail end pressing piece and a cylinder.
[0035] Before the triangular piece flips, a webbing front end pressing and fixing plate and a webbing pressing plate are provided on the support plate.
[0036] A rotary cylinder fixing block is provided on the support plate before the triangular piece flips, and a triangular piece flipping rod is provided on the rotary cylinder fixing block;
[0037] Before the triangular piece flips, a triangular piece detection sensor is installed on the support plate, and the triangular piece detection sensor is connected to a diffuse reflection photoelectric switch.
[0038] The triangular piece is displaced by the linear module and placed on the platform of the folding and flipping mechanism. The triangular piece is then fixed below the platform using vacuum suction. At this point, the tail wing pressing mechanism of the material-picking and pressing mechanism presses down to fix the triangular piece. Then, the tail wing folding mechanism of the folding and flipping mechanism rises and extends, then retracts to fold the tail wing of the triangular piece (the width of the folded tail wing is adjustable). The tail wing folding mechanism then presses down to fix the folded tail wing. At this point, the tail wing pressing mechanism extends, rises, and retracts; this completes the tail wing folding action of the triangular piece. Simultaneously, the webbing traction clamp clamps the webbing at the waiting station. When the triangular piece picking mechanism returns to its original position, the webbing traction mechanism... The process begins with pulling the webbing to the webbing feed position. Then, the webbing clamping mechanism descends, and the webbing rear end pressing mechanism presses down to fix the webbing. The webbing clamp then opens and retracts, exiting the webbing feed position and rising back to its original position. At this time, the webbing front end pressing mechanism extends and presses down to fix the front end of the webbing. Then, the triangular piece folding and flipping mechanism folds and flips the triangular pieces in half, with the left and right ends of the folded pieces neatly and symmetrically overlapping. Then, the triangular piece webbing finished product pressing mechanism rises, extends, and presses down to fix the corners of the triangular pieces. Then, the tail wing pressing mechanism opens, retracts, and closes to exit the tail wing and fix it. Finally, it flips back to its original position. At this time, the electromagnetic induction output signal for flipping back to its original position is sent to the computer sewing machine.
[0039] Preferably, the sewing mechanism is equipped with a material-taking mechanism.
[0040] The sewing mechanism adopts a structure already available on the market in this field, specifically the Mitsubishi 3520 model. The material-taking mechanism consists of a rodless cylinder that extends after displacement along the X-axis of the sewing machine. A sliding cylinder then presses down to secure the folded triangular webbing. Signals are exchanged between the triangular webbing's tail end pressure cylinder and the computerized sewing machine, releasing all securing mechanisms. The material is then displaced along the X-axis of the computerized sewing machine, and the rodless cylinder returns to its original position, sending a signal back to the computerized sewing machine. The sewing machine then begins sewing. After sewing, a finished product pusher plate pushes the finished webbing onto the hanging beam. A finished product rotation cylinder rotates the finished product, flipping it over and hanging it above the square tube surface of the hanging beam. The material-taking mechanism then picks up the folded and hemmed triangular pieces and places them onto the sewing mechanism for sewing. After the triangular webbing completes the processes of folding the tail fins, securing the webbing, and folding the triangular pieces, the computerized sewing machine is activated by a received electromagnetic signal. The slider of the rodless cylinder on the X-axis side-sliding mechanism of the computerized sewing machine extends above the semi-finished product. At this time, the fabric clamping fixture presses down, and the cylinder of the webbing material-taking mechanism presses down. The pressing action is then completed via electromagnetic induction. The front and rear end pressing mechanisms of the webbing and the semi-finished product pressing mechanism return to their original positions. Then, the side-sliding mechanism presses the material and slides back to its original position. The electromagnetic induction signal from the rodless cylinder of the side-sliding mechanism after returning to its original position is sent to the computerized sewing machine, which then starts sewing. After sewing is completed, the side-sliding pressing mechanism returns to the waiting position to await the electromagnetic signal.

[0057] In this embodiment:
[0058] First, a roll of webbing is manually placed into the webbing tray. Then, a stack of triangular pieces is placed into the triangular piece hopper. The webbing is manually guided through the webbing guide frame, through the webbing guide groove, the webbing feeding wheel, and the webbing front end guide groove to the plane above the ultrasonic transducer cutter. After the triangular pieces are flattened, the triangular piece hopper guide column is pushed so that its tail end face is aligned with the blocking surface. When the machine starts, the webbing feeding upper pressure wheel presses down on the upper plane of the webbing. The feeding method is driven by the motor to the synchronous belt pulley, which makes the webbing feeding wheel rotate. When restarting, the webbing feeding wheel will pre-feed a section of webbing again for a cutting action. The cutting method is a rotary punching method, which allows the front and rear ends of the webbing to be cut into any angle.
[0059] Secondly, after the cutting is completed, a secondary feeding is performed to pre-feed the webbing head. At this time, the webbing clamp is in the opening, closing, rising, and retracting state. After sensing that the webbing pre-feeding is completed, the webbing clamp extends and closes to clamp the webbing, and then sends it to the waiting position to wait. At the same time, when the triangular piece hopper is started, the material in the hopper will automatically rise in the Y direction through the material picking sensor to find the sensing position and stop. At this time, the triangular piece picking mechanism will lower the cylinder and start the vacuum suction. The triangular piece is picked up and raised by the negative pressure of the suction cup. The vacuum negative pressure value of the triangular piece picking is used to determine whether there is a triangular piece on the suction cup. In addition, when the displacement reaches the triangular piece detection sensor, the suction cup will be checked a second time to see if there is material on the piece. The linear module will move the triangular piece to the feeding position. Then the suction cup picking mechanism cylinder will lower, and the vacuum suction cup under the folding plate of the triangular piece tail wing will be activated by the electromagnetic induction of the cylinder descent.
[0060] Next, after the triangular piece is adsorbed and fixed, the triangular piece picking mechanism breaks the vacuum and rises back to the picking position to adsorb another triangular piece and wait. At this time, the front end of the webbing rises, and at the same time, the tail wing pressing mechanism of the triangular piece presses down, and the tail wing spring clip presses the triangular piece tightly. Then, the tail wing folding cylinder rises, retracts, and falls to complete the folding process of the tail wing of the triangular piece. In the next step, the tail wing pressing mechanism of the triangular piece extends horizontally and exits the folded tail wing part of the triangular piece. The cylinder rises and retracts to the waiting position. At this time, the webbing traction linkage begins to send the clamped webbing to the unloading position. Then the webbing clamp falls, and the rear end pressing mechanism of the webbing falls to press the webbing surface and fix the position of the webbing. Then the webbing clamp opens, retracts (then the front end pressing mechanism of the webbing extends and presses down to fix the front end of the webbing), rises, and returns to the webbing picking position.
[0061] Then, when the webbing clamping mechanism moves past the webbing traction waiting position, the induction signal is output to the triangular piece flipping and folding mechanism. The flipping cylinder flips the triangular piece 180°, folding it in half. The electromagnetic signal is output through the rotary cylinder, and then the folding pressing mechanism rises, extends, presses down, and presses the folded triangular piece webbing tightly. Next, the triangular piece tail wing folding mechanism rises, extends, descends, and returns to the original position. At this time, the triangular piece folding mechanism rotates back to the original position. When flipping back to the original position, the flipping back electromagnetic induction output signal is sent to the computer sewing machine. The computer sewing machine's X-axis slides out and the material picking mechanism on the aircraft frame presses down to fix the semi-finished product. Then, the pressing action is completed by electronic sensing, and the front and rear end pressing mechanisms of the webbing and the triangular piece webbing semi-finished product pressing mechanism return to their original positions, and the tail wing vacuum suction closes.
[0062] Finally, the side-sliding pressing material is moved to the sewing position of the computerized sewing machine. Then, the electromagnetic induction signal of the rodless cylinder of the side-sliding position is output, starting the computerized sewing machine to sew. After the sewing is completed, the side-sliding material picking mechanism returns to the waiting position to wait for the next material. After the sewing is completed, the aircraft frame is raised and an electronic induction signal is output. At this time, the triangular piece webbing finished product pushing mechanism extends to press the webbing, and then the finished product flipping mechanism rotates the rod to flip and pick up the finished product and place it on the material beam. At this time, the entire finished product action is completed.
[0063] The above-disclosed example is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
