Description

Technical Field

[0001] This application relates to the field of textile machinery and equipment technology, and in particular to an automatic feeding and knotting device. Background Technology

[0002] In garment production, bar binding and bar stitching are key processes in garment forming. In traditional production processes, after the bar binding process is completed, the cut pieces are manually stretched, turned over, and fed to the bar stitching machine. This process is cumbersome, inconsistent, and affects production efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide an automatic feeding and knotting device to realize automatic feeding in the knotting process.

[0004] An automatic feeding and knotting device includes a frame, a transfer module, a clamping mechanism, and a knotting machine;

[0005] The transfer module is mounted on the frame; the clamping mechanism is mounted on the transfer module, and the clamping mechanism includes a clamping lifting component, a clamping mounting component, a first clamping component, a second clamping component, and a tensioning drive component. The clamping lifting component is connected to the transfer module and the clamping mounting component to drive the clamping mounting component to lift. The first clamping component and the second clamping component are respectively mounted on the clamping mounting component and arranged opposite to each other. The first clamping component is movably connected to the clamping mounting component. The tensioning drive component is connected to the first clamping component to drive the first clamping component to move or reset in a direction away from the second clamping component. The transfer module is used to transfer the clamping mechanism, which has completed clamping, to the knotting machine.

[0006] In some embodiments, the transfer module includes a first driving component and a second driving component, the first driving component being used to drive the clamping mechanism to move along a first horizontal direction, and the second driving component being used to drive the clamping mechanism to move along a second horizontal direction, wherein the first horizontal direction is perpendicular to the second horizontal direction.

[0007] In some embodiments, the first clamping component includes a first connector, a first clamping lifting driver, a first movable clamping component, and a first fixed clamping component. The first connector is slidably engaged with the clamping mounting component. The tensioning driving component is connected to the first connector to drive the first connector to slide. The first fixed clamping component is disposed on the first connector. The first clamping lifting driver is disposed on the first connector and connected to the first movable clamping component. The first clamping lifting driver is used to drive the first movable clamping component to descend to abut against the first fixed clamping component or to reset.

[0008] In some embodiments, the second clamping component includes a second connector, a second clamping lifting driver, a second movable clamping component, and a second fixed clamping component. The second connector is connected to the clamping mounting component, the second fixed clamping component is disposed on the second connector, the second clamping lifting driver is disposed on the second connector and connected to the second movable clamping component, and the second clamping lifting driver is used to drive the second movable clamping component to descend to abut against the second fixed clamping component or to reset.

[0009] In some embodiments, the first clamping lifting driver is a cylinder or a motor screw drive assembly.

[0010] In some embodiments, the second clamping lifting driver is a cylinder or a motor screw drive assembly.

[0011] In some embodiments, the tensioning drive component is a cylinder or a motor screw drive assembly.

[0012] In some embodiments, the clamping and lifting component is a cylinder or a motor screw drive assembly.

[0013] In some embodiments, the automatic feeding and knotting device further includes a clamping status sensor, which is used to detect whether the first clamping component and the second clamping component are clamping the cut piece after the clamping mechanism completes the clamping action. When the clamping status sensor detects that the first clamping component and the second clamping component are clamping the cut piece, the transfer module transfers the clamping mechanism to the knotting machine.

[0014] In some embodiments, the automatic feeding and knotting device further includes an edge-finding sensor and a control system. The edge-finding sensor is used to detect the edge position of the cut piece that has moved to the knotting machine and feed it back to the control system. The control system calculates the knotting reference point based on the edge position.

[0015] In some embodiments, the automatic feeding and knotting device further includes a bone position sensor for detecting the bone position height of the cut piece moving to the knotting machine. When the bone position sensor detects that the bone position height is within a preset range, the knotting machine starts knotting on the cut piece.

[0016] In some embodiments, the automatic feeding and knotting device further includes a yarn breakage sensor, which is used to detect the yarn status of the knotting machine. When the yarn breakage sensor detects a yarn breakage in the knotting machine, the knotting machine stops working.

[0017] Compared with traditional solutions, the above-mentioned automatic feeding and knotting device has the following advantages:

[0018] The aforementioned automatic feeding and knotting device enables automatic feeding and knotting of the material discharged from the mesh leg machine. Specifically, after the mesh leg machine discharges material, the transfer module drives the clamping mechanism to move above the discharge position of the mesh leg machine. The clamping lifting component drives the clamping mounting component, the first clamping component, and the second clamping component to descend to the material picking height. The first clamping lifting driver drives the first moving clamping component to descend, closing it with the first fixed clamping component. The second clamping lifting driver synchronously drives the second moving clamping component to descend, closing it with the second fixed clamping component, thus clamping the edge of the cut piece. The clamping lifting component rises, causing the cut piece to detach from the mesh leg machine table. The tensioning drive component drives the first clamping component to move away from the second clamping component, laterally spreading and tensioning the cut piece. The transfer module, through the actions of the first and second drive components, transfers the clamping mechanism and the cut piece to the designated position of the knotting machine, where the knotting machine performs the knotting. The aforementioned automatic feeding and knotting device can improve the automation level of knotting work and save labor costs. Attached Figure Description

[0028] like Figure 1As shown, an automatic feeding and knotting device 100 according to an embodiment of this application includes a frame (not shown), a transfer module 120, a clamping mechanism 130, and a knotting machine 140.

[0029] The transfer module 120 is mounted on the frame. The clamping mechanism 130 is mounted on the transfer module 120. The clamping mechanism 130 includes a clamping lifting component 131, a clamping mounting component 132, a first clamping component 133, a second clamping component 134, and a tensioning drive component 135. The clamping lifting component 131 is connected to the transfer module 120 and the clamping mounting component 132 to drive the clamping mounting component 132 to move up and down. The first clamping component 133 and the second clamping component 134 are respectively mounted on the clamping mounting component 132 and arranged opposite to each other. The first clamping component 133 is movably connected to the clamping mounting component 132. The tensioning drive component 135 is connected to the first clamping component 133 to drive the first clamping component 133 to move or reset in a direction away from the second clamping component 134. The transfer module 120 is used to transfer the clamping mechanism 130, after clamping, to the knotting machine 140.

[0030] After the mesh leg machine discharges material, the transfer module 120 drives the clamping mechanism 130 to move above the discharge position of the mesh leg machine. The clamping lifting component 131 drives the clamping mounting component 132 and the first clamping component 133 and the second clamping component 134 to descend to the material picking height. The first clamping lifting driver 1332 drives the first moving clamping component 1333 to descend, so that the first moving clamping component 1333 closes with the first fixed clamping component 1334. The second clamping lifting driver 1342 synchronously drives the second moving clamping component 1343 to descend, so that the second moving clamping component 1343 closes with the second fixed clamping component 1344, completing the clamping of the cut piece edge. The clamping lifting component 131 rises, causing the cut piece to detach from the mesh leg machine table. The tensioning drive component 135 drives the first clamping component 133 to move away from the second clamping component 134, horizontally opening and tensioning the cut piece. The transfer module 120 moves through the first drive component 121 and the second drive component 122 to transfer the clamping mechanism 130 and the cut piece to the designated position of the knotting machine 140, where the knotting machine 140 performs knotting.

[0031] In some examples, the transfer module 120 includes a first drive component 121 and a second drive component 122. The first drive component 121 is used to drive the clamping mechanism 130 to move along a first horizontal direction, and the second drive component 122 is used to drive the clamping mechanism 130 to move along a second horizontal direction.

[0032] The first horizontal direction and the second horizontal direction are different directions. In some examples, the first horizontal direction is perpendicular to the second horizontal direction.

[0033] After the mesh leg machine outputs material, when the cut piece needs to be flipped, the clamping mechanism 130 grabs the edge of the cut piece from the low position of the output end of the mesh leg machine, lifts it vertically to suspend it in the air, and then the tensioning drive component 135 opens the cut piece. With the horizontal conveying path of the first drive component 121 and the second drive component 122, the cut piece naturally completes the posture change during the process of conveying from the mesh leg machine to the knotting machine 140. The automatic adaptation of the cut piece from the sewing posture of the mesh leg process to the feeding posture of the knotting process can be achieved without manual intervention.

[0034] In some of these examples, the first drive component 121 is a moving module. In some of these examples, the second drive component 122 is a moving module.

[0035] In some examples, the first clamping component 133 includes a first connector 1331, a first clamping lifting driver 1332, a first movable clamping component 1333, and a first fixed clamping component 1334. The first connector 1331 is slidably engaged with the clamping mounting component 132. A tensioning drive component 135 is connected to the first connector 1331 to drive the first connector 1331 to slide. The first fixed clamping component 1334 is disposed on the first connector 1331, and the first clamping lifting driver 1332 is disposed on the first connector 1331 and connected to the first movable clamping component 1333. The first clamping lifting driver 1332 is used to drive the first movable clamping component 1333 to descend to abut against the first fixed clamping component 1334 or to reset.

[0036] In some examples, the second clamping component 134 includes a second connector 1341, a second clamping lifting driver 1342, a second movable clamping component 1343, and a second fixed clamping component 1344. The second connector 1341 is connected to the clamping mounting component 132. The second fixed clamping component 1344 is disposed on the second connector 1341, and the second clamping lifting driver 1342 is disposed on the second connector 1341 and connected to the second movable clamping component 1343. The second clamping lifting driver 1342 is used to drive the second movable clamping component 1343 to descend to abut against the second fixed clamping component 1344 or to reset.

[0037] In the above example, in standby mode, the clamping mechanism 130 is in a high position, avoiding the material output path of the mesh leg machine. When clamping the cut piece, the clamping lifting component 131 extends downward, driving the first clamping component 133 and the second clamping component 134 to descend to the clamping position. The first clamping lifting driver 1332 drives the first movable clamping component 1333 to descend to abut against the first fixed clamping component 1334, and the second clamping lifting driver 1342 drives the second movable clamping component 1343 to descend to abut against the second fixed clamping component 1344, thereby clamping the edge of the cut piece with the first clamping component 1333 and the second clamping component 134. The clamping lifting component 131 is driven upward, pulling the cut piece from the mesh leg machine table and suspending it in the air. The tensioning drive component 135 drives the first clamping component 133 to move away from the second clamping component 134, evenly stretching and tensioning the cut piece, eliminating wrinkles and keeping the edges straight, preparing for subsequent knotting and positioning.

[0038] In some examples, the first clamping lifting actuator 1332 is a cylinder. When the first clamping lifting actuator 1332 extends, it drives the first movable clamping member 1333 to descend and abut against the first fixed clamping member 1334, clamping the cut piece. When the first clamping lifting actuator 1332 retracts, it releases the cut piece. It is understood that in other examples, the first clamping lifting actuator 1332 is not limited to using a cylinder, and may also use other drive structures, such as a motor screw drive assembly.

[0039] In some examples, the second clamping lifting driver 1342 is a cylinder. In other examples, the second clamping lifting driver 1342 is not limited to using a cylinder, and may also use other drive structures, such as a motor screw drive assembly.

[0040] In some examples, the tension drive component 135 is a cylinder. In other examples, the tension drive component 135 is not limited to a cylinder and may also employ other drive structures, such as a motor screw drive assembly.

[0041] In some examples, the clamping and lifting component 131 is a cylinder. In other examples, the clamping and lifting component 131 is not limited to using a cylinder, and may also use other drive structures, such as a motor screw drive assembly.

[0042] In some examples, the automatic feeding and knotting device 100 also includes a clamping status sensor 150. The clamping status sensor 150 is used to detect whether the first clamping component 133 and the second clamping component 134 are clamping the cut piece after the clamping mechanism 130 completes the clamping action. When the clamping status sensor 150 detects that the first clamping component 133 and the second clamping component 134 are clamping the cut piece, the transfer module 120 transfers the clamping mechanism 130 to the knotting machine 140.

[0043] A successful clamping sensor may be mounted on the first clamping component 133 and / or the second clamping component 134. The successful clamping sensor may be a photoelectric sensor or a contact microswitch. The successful clamping sensor determines whether the clamping is successful by detecting whether there is a cut piece between the grippers of the first clamping component 133 and the second clamping component 134 after the clamping action.

[0044] In some examples, the automatic feeding and knotting device 100 also includes an edge-finding sensor 160. The edge-finding sensor 160 is used to detect the edge position of the cut piece moving to the knotting machine 140 and feed it back to the control system, which calculates the knotting reference point based on the edge position.

[0045] In the example above, by setting the edge-finding sensor 160, the edge position of the moving cut piece is detected, preventing the knot position from shifting and improving the consistency of garment processing.

[0046] The edge-finding sensor 160 can be mounted on, for example, the knotting machine 140. The edge-finding sensor 160 can be, for example, a photoelectric sensor.

[0047] In some examples, the automatic feeding and knotting device 100 also includes a bone position sensor 170. The bone position sensor 170 is used to detect the bone position height of the cut piece moving to the knotting machine 140. When the bone position sensor 170 detects that the bone position height is within a preset range, the knotting machine 140 starts knotting on the cut piece.

[0048] The bone position sensor 170 can be mounted on, for example, the knotting machine 140. The bone position sensor 170 can be, for example, a contact probe sensor.

[0049] In some examples, the automatic feeding and knotting device 100 also includes a yarn breakage sensor 180. The yarn breakage sensor 180 is used to detect the yarn condition of the knotting machine 140. When the yarn breakage sensor 180 detects a yarn breakage in the knotting machine 140, the knotting machine 140 stops operating.

[0050] Other structural features of the knotting machine 140 can adopt a conventional structure. When implementing the solution of this application, those skilled in the art can adopt a conventional knotting device or a knotting device improved thereon as needed.

[0051] Understandably, the actions of each component in the above-mentioned automatic feeding and knotting device 100 can be controlled by control systems commonly used in the art, such as, but not limited to, industrial computers, programmable logic controllers (PLCs), etc.

[0052] The automatic feeding and knotting device 100, as illustrated in the figure, includes the following steps in its automatic feeding and knotting method:

[0053] Step S1: After the control system receives the signal that the mesh foot machine has finished discharging, the transfer module 120 drives the clamping mechanism 130 to move above the discharging position of the mesh foot machine.

[0054] In step S2, the clamping lifting component 131 drives the clamping mounting component 132, the first clamping component 133, and the second clamping component 134 to descend as a whole to the material picking height.

[0055] In step S3, the first clamping lifting driver 1332 drives the first moving clamping member 1333 to descend, so that the first moving clamping member 1333 closes with the first fixed clamping member 1334; the second clamping lifting driver 1342 synchronously drives the second moving clamping member 1343 to descend, so that the second moving clamping member 1343 closes with the second fixed clamping member 1344, thus completing the clamping of the cut piece edge.

[0056] Step S4: The clamping status sensor 150 detects whether the cut piece is successfully clamped. Specifically, it detects whether there is a cut piece between the grippers of the first clamping component 133 and the second clamping component 134 after the clamping action. If a cut piece is detected, the clamping is successful and proceeds to the next step; if no cut piece is detected, the clamping fails, the device stops and an alarm is issued.

[0057] In step S5, the clamping lifting component 131 rises, causing the cut piece to detach from the mesh foot machine table; the tensioning drive component 135 drives the first clamping component 133 to move away from the second clamping component 134, thus horizontally opening and tensioning the cut piece.

[0058] In step S6, the transfer module 120, through the coordinated action of the first drive component 121 and the second drive component 122, transfers the clamping mechanism 130 and the cut piece to the designated position of the knotting machine 140.

[0059] In step S7, the edge-finding sensor 160 detects the edge position of the cut piece and feeds it back to the control system. The control system calculates and determines the reference point for knotting.

[0060] In step S8, the bone position sensor 170 detects the bone position height of the cut piece and determines whether it is within the preset acceptable range. If the bone position height is within the preset range, the knotting machine 140 starts knotting on the cut piece. At the same time, the thread breakage sensor 180 detects whether the yarn of the knotting machine 140 is normal.

[0061] Step S9: When the bobbin position is qualified and the yarn is normal, the knotting machine 140 starts the presser foot and performs the knotting action; if any condition is not met, the knotting machine 140 is prohibited from starting and an abnormality is indicated.

[0062] Step S10: After the knotting is completed, the pressure foot of the knotting machine 140 is lifted, the first clamping lifting driver 1332 and the second clamping lifting driver 1342 rise and reset, the tensioning drive component 135 resets, and the clamping mechanism 130 releases the cut piece.

[0063] Step S11: The transfer module 120 drives the clamping mechanism 130 to reset.

[0064] The aforementioned automatic feeding and knotting device 100 can automatically feed and knot the material discharged from the mesh foot machine. Specifically, after the mesh leg machine discharges material, the transfer module 120 drives the clamping mechanism 130 to move above the discharge position of the mesh leg machine. The clamping lifting component 131 drives the clamping mounting component 132 and the first clamping component 133 and the second clamping component 134 to descend to the material picking height. The first clamping lifting driver 1332 drives the first moving clamping component 1333 to descend, so that the first moving clamping component 1333 closes with the first fixed clamping component 1334. The second clamping lifting driver 1342 synchronously drives the second moving clamping component 1343 to descend, so that the second moving clamping component 1343 closes with the second fixed clamping component 1344, completing the clamping of the cut piece edge. The clamping lifting component 131 rises, causing the cut piece to detach from the mesh leg machine table. The tensioning drive component 135 drives the first clamping component 133 to move away from the second clamping component 134, thus laterally opening and tensioning the cut piece. The transfer module 120, through the operation of the first drive component 121 and the second drive component 122, transfers the clamping mechanism 130 and the cut piece to a designated position of the knotting machine 140, where the knotting machine 140 performs the knotting. The aforementioned automatic feeding and knotting device 100 can improve the automation level of the knotting operation and save labor costs.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
