[0046] In order to more clearly illustrate the structure of the track sewing device 1, the track sewing device 1 will be described in detail below in combination with the drawings.

[0047] The track sewing device 1 is exemplarily shown in Figures 1-2 , and the track sewing device 1 comprises a workbench 10, a moving mechanism 20 and a pressing mechanism 30.

[0048] The workbench 10 is provided with a cutting piece placing station and a sewing station, and the cutting piece placing station is arranged adjacent to the sewing station. The cutting piece placing station is used for placing the cutting piece 2, and the sewing station is used for sewing the cutting piece 2.

[0049] The moving mechanism 20 is located above the workbench 10, and the moving mechanism 20 comprises a first moving mechanism 21 and a second moving mechanism 22. The first moving mechanism 21 is installed on the workbench 10 and connected to the second moving mechanism 22. The first moving mechanism 21 is used to drive the second moving mechanism 22 to move up and down vertically to the table top of the workbench 10. When the second moving mechanism moves upward, it is convenient for the operator to replace the pressing mechanism 30 and place the cutting piece 2.

[0050] The pressing mechanism 30 is movably connected to the second moving mechanism 22. The second moving mechanism 22 is used to drive the pressing mechanism 30 and the cutting piece 2 pressed by the pressing mechanism 30 to move in parallel to the table top of the workbench 10 along a preset track. The preset track has the same shape as the target sewing track and the guide rail. The speed of the second moving mechanism driving the pressing mechanism 30 and the cutting piece 2 pressed by the pressing mechanism 30 to move can be adjusted. The pressing mechanism 30 is movably connected to the second moving mechanism 22, which facilitates the replacement of the suitable pressing mechanism 30 according to the different target sewing tracks.

[0051] In some embodiments, the pressing mechanism can be a pressing plate, and the pressing plate is provided with first guide rails 311 and second guide rails 312 parallel to each other. The guide rail tracks of the first guide rails 311 and the second guide rails 312 are preset tracks, and the suitable guide rail shapes can be selected according to the different target sewing tracks.

[0052] In some embodiments, the preset track can be curved, zigzag or straight. Specifically, the preset track can be arc-shaped, U-shaped, V-shaped or I-shaped, without particular limitation.

[0053] In some embodiments, referring to Figures 1-2 As shown in the figure, the first moving mechanism 21 comprises a first driving member and a first fixing seat, and the first driving member is installed on the workbench 10 through the first fixing seat.

[0054] It can be understood that the first driving member can be any driving member capable of realizing the telescopic function, such as a pneumatic cylinder or an electric push rod.

[0055] In some embodiments, referring to Figures 1-2 As shown in the figure, the first driving member is a pneumatic cylinder 211, and the first fixing seat is a pneumatic cylinder fixing seat 212, and the pneumatic cylinder 211 is installed on the workbench 10 through the pneumatic cylinder fixing seat 212.

[0056] It should be noted that the pneumatic cylinder 211 and the pneumatic cylinder fixing seat 212 can adopt various connection modes, and preferably are fixedly connected or detachably connected for stability.

[0057] For example, the pneumatic cylinder fixing seat 212 is provided with a plurality of adjusting threaded holes, and the pneumatic cylinder 211 is fixed on the pneumatic cylinder fixing seat 212 through the connection of screws and the adjusting threaded holes, and then is installed on the workbench 10 through the pneumatic cylinder fixing seat 212.

[0058] In some embodiments, the first moving mechanism 21 is arranged on the side of the cutting piece placement station close to the sewing station.

[0059] In some embodiments, the second driving mechanism comprises a second driving member and a second fixing seat, and the second driving member is connected to the first driving mechanism through the second fixing seat.

[0060] It should be noted that the second driving member can be a power source such as a motor or a heat engine. Preferably, the second driving member is a motor.

[0061] In some embodiments, referring to Figures 1-2 As shown in the figure, the second driving member in the second moving mechanism 22 is a motor 221, the second fixing seat is a motor fixing seat 222, and the motor 221 is connected to the output end of the first moving mechanism 21 through the motor fixing seat 222. The output direction of the first moving mechanism 21 is vertically downward, and the first moving mechanism 21 drives the motor 221 to move up and down vertically to the tabletop of the workbench 10. When the first moving mechanism 21 drives the motor 221 to move upward, the second moving mechanism 22 is separated from the material pressing mechanism 30, and when the first moving mechanism 21 drives the motor 221 to move downward, the second moving mechanism 22 is connected to the material pressing mechanism 30 and presses the cutting piece 2.

[0062] In some embodiments, motor 221 can be a servo motor, stepper motor, torque motor, switched reluctance motor, or brushless DC motor. Preferably, motor 221 is a stepper motor.

[0063] In some of these implementations, such as Figures 1-2 As shown, the output shaft of motor 221 passes through motor mounting base 222. The output of motor 221 and the main body of motor 221 are located on both sides of motor mounting base 222, with the output shaft of motor 221 located on the side of motor mounting base 222 closer to the pressing mechanism.

[0064] In some of these implementations, please refer to Figures 1-2 As shown, the second moving mechanism 22 also includes a gear 224 and a guide bearing 223. The gear 224 is connected to the output shaft of the motor 221, and the guide bearing 223 is arranged parallel to the gear 224 and connected to the motor mounting base 222. The second moving mechanism 22 is movably connected to the first guide rail 311 and the second guide rail 312 on the pressure plate through the gear 224 and the guide bearing 223, respectively.

[0065] In some embodiments, a rack 313 adapted to the gear 224 is provided on one side of the first guide rail 311, or racks 313 adapted to the gear 224 are provided on both sides of the first guide rail 311.

[0066] When motor 221 drives gear 224 to rotate along the rack within the first guide rail 311, it drives guide bearing 223, pressing mechanism 30, and the cut piece 2 pressed by pressing mechanism 30 to rotate parallel to the worktable 10 along the target sewing trajectory. Guide bearing 223 serves to guide and position, ensuring the stability of pressing mechanism 30 and the cut piece 2 pressed by it, so that the cut piece 2 moves strictly according to the target sewing trajectory, thus ensuring sewing quality.

[0067] The track sewing device of the present invention, by setting a double guide rail structure of first guide rail 311 and second guide rail 312, not only enables the cut piece 2 to move along the preset sewing trajectory during sewing, but also ensures the stability of the track sewing device 1 operation, avoids problems such as movement and deviation caused by vibration during operation, and improves product quality.

[0068] In some embodiments, the track sewing device 1 further includes a sewing mechanism 40, which is mounted on the worktable 10 for sewing the cut pieces 2.

[0069] In some embodiments, the track sewing device 1 further comprises a control mechanism. The control mechanism can be a programmable logic controller (PLC). The first moving mechanism 21, the second moving mechanism 22 and the driving components in the sewing mechanism 40 are electrically connected to the control mechanism for automatic control function. The programmable logic controller can control the automation and precision of the sewing production process through digital or analog input and output, and improve the sewing production efficiency.

[0070] In some embodiments, the sewing mechanism 40 is installed on the sewing station of the workbench 10, and comprises a sewing head, a sewing needle, a needle column, a needle column driving component, a presser foot lifting component and a presser foot 411 (not fully shown in the figure). The sewing head is installed on the workbench 10. The needle column driving component is connected to the sewing head and the needle column for driving the needle column to move. The sewing needle is installed in the needle column and can move with the needle column. The presser foot lifting component is arranged on the sewing head and connected to the needle column driving component and the presser foot 411. When the needle column driving component drives the needle column to move, the needle column driving component can drive the presser foot 411 to move in linkage with the needle column by driving the presser foot lifting component. The needle column driving component is electrically connected to the control mechanism.

[0071] In some embodiments, the control mechanism controls the needle column driving component on the sewing head of the sewing mechanism 40 to drive the needle column to move synchronously with the presser foot 411, so that the needle column is pressed down at the same time as the presser foot 411 is pressed down on the piece 2, which plays a role in fixing the piece 2 to cooperate with the sewing of the piece 2 by the sewing needle. When the needle column is lifted up, the presser foot 411 is lifted up with the needle column, so that the piece 2 can pass through the presser foot 411, and the piece 2 can be moved along the target sewing track route under the driving of the second moving mechanism 22, to realize the sewing of the piece 2 with various sewing tracks. The speed of the needle column driven by the needle column driving component on the sewing head of the sewing mechanism 40 to move with the presser foot 411 can be adjusted.

[0072] In some embodiments, the track sewing device 1 further comprises a thread cutting mechanism (not shown in the figure). The thread cutting mechanism is installed on the table top of the workbench 10 for cutting the thread on the piece 2 after sewing. The thread cutting mechanism is electrically connected to the control mechanism.

[0073] In some embodiments, the track sewing device 1 further comprises a material collecting mechanism (not shown in the figure) installed on the workbench 10 for collecting the piece 2 after sewing by the sewing mechanism 40. The material collecting mechanism is electrically connected to the control mechanism. The track sewing device of the present application can be used to automatically collect the piece 2 after sewing by the sewing mechanism 40 by providing the material collecting mechanism, which omits the manual material collecting process, reduces the labor cost and improves the production efficiency.

[0074] In some embodiments, the material collecting mechanism comprises a material collecting arm and a material collecting driving component, the material collecting driving component is installed on the workbench 10 and connected to the material collecting arm, and the material collecting driving component is used to drive the material collecting arm to move. The material collecting driving component is electrically connected to the control mechanism.

[0075] In some embodiments, the track sewing device 1 further comprises a material collecting box (not shown in the figure), which is installed on the workbench 10 and used to collect the pieces 2 after sewing.

[0076] When the track sewing device 1 of the present application is used, the specific process is as follows:

[0077] The control mechanism controls the first moving mechanism 21 to move upward vertically to the surface of the workbench 10, and drives the second moving mechanism 22 to move upward vertically to the surface of the workbench 10. At this time, the gear 224 and the guide bearing 223 are separated from the first guide rail 311 and the second guide rail 312 on the material pressing mechanism 30, so that the manual or mechanical feeding claw can place the piece 2 to be processed below the material pressing mechanism 30 on the piece placing station. For the piece 2 to be processed for different target sewing tracks, the material pressing mechanism 30 with a guide rail shape suitable for the target sewing track can be replaced.

[0078] After the piece 2 and the material pressing mechanism 30 are placed, the control mechanism controls the first moving mechanism 21 to move downward vertically to the surface of the workbench 10, and drives the second moving mechanism 22 to move downward vertically to the surface of the workbench 10. At this time, the gear 224 and the guide bearing 223 are connected with the first guide rail 311 and the second guide rail 312 on the material pressing mechanism 30, and drive the material pressing mechanism 30 to move downward, so that the material pressing mechanism 30 exerts pressure on the piece 2. The material pressing mechanism 30 presses the piece 2, which plays a role of positioning and fixing the piece 2 at this time.

[0079] The control mechanism controls the second moving mechanism 22 to drive the gear 224 to rotate along the guide rail track, and drives the material pressing mechanism 30 and the piece 2 pressed by the material pressing mechanism 30 to move.

[0080] While the piece 2 is moving, the control mechanism controls the needle column driving component on the sewing head of the sewing mechanism 40 to drive the needle column and the pressing shoe 411 to move synchronously, so that the needle column is lowered at the same time as the pressing shoe 411 is lowered on the piece 2, to cooperate with the sewing needle to complete the sewing of the piece 2. When the needle column rises, the pressing shoe 411 rises with the needle column, so that the piece 2 can pass through the pressing shoe 411 and can realize the turning of the piece 2 under the driving of the second driving component 22.

[0081] When the piece 2 is sewn, the control mechanism controls the second driving component 22 and the sewing mechanism 40 to stop working, and the control mechanism controls the thread cutting mechanism to cut the thread on the piece 2.

[0082] After the cutting thread is cut off, the control mechanism controls the material receiving driving part to drive the material receiving arm to put the cutting piece 2 into the material receiving box.

[0083] In some embodiments, the track sewing device 1 further comprises a positioning mechanism (not shown in the figure) for indicating the cutting piece placement area. When the cutting piece 2 is placed on the cutting piece placement station, the operator can place the cutting piece 2 on the cutting piece placement station according to the mark line projected by the positioning mechanism, which improves the accuracy of the cutting piece placement operation and simplifies the operation process. The positioning mechanism is electrically connected to the control mechanism.

[0084] In some embodiments, the positioning mechanism can be a laser positioning lamp, an infrared positioning lamp or a laser positioning lamp. Preferably, the positioning mechanism is a laser positioning lamp.

[0085] The track sewing device described above comprises a workbench, a moving mechanism and a material pressing mechanism. The material pressing mechanism and the cutting piece pressed by the material pressing mechanism move along the preset track parallel to the table top of the workbench driven by the moving mechanism, so that the cutting piece can move strictly according to the target sewing track, saving manpower and improving production efficiency.

[0086] The track sewing device described above adopts a double-rail arrangement of a first guide rail and a second guide rail. The second moving mechanism drives the gear and the guide bearing to move along the first guide rail and the second guide rail respectively, ensuring the stability of the movement of the material pressing mechanism and the cutting piece pressed by the material pressing mechanism, preventing the cutting piece sewing track from deviating due to shaking or unstable movement, so that the cutting piece can move according to the target sewing track, improving the quality of cutting piece sewing.

[0087] The track sewing device described above. The second moving mechanism drives the material pressing mechanism and the cutting piece pressed by the material pressing mechanism to move through the driving gear. The gear can improve the friction between the second driving mechanism and the cutting piece below the material pressing mechanism, ensuring the normal movement of the cutting piece below the material pressing mechanism.

[0088] The track sewing device described above. The second moving mechanism and the material pressing mechanism are separable, which facilitates the operator to replace the appropriate material pressing mechanism in time according to the target sewing track, has strong flexibility and can meet the requirements of cutting pieces with different sewing tracks.

[0089] The track sewing device described above adopts a control mechanism to control the orderly progress of the sewing program, realizes the automation and precision of the production process, and improves the efficiency of the sewing production.

[0090] The track sewing device described above adopts a positioning mechanism to indicate the cutting piece placement area. The operator can place the cutting piece according to the mark line projected by the positioning mechanism, which improves the accuracy of the cutting piece placement operation and simplifies the operation process.
