[0030] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 One embodiment of the intelligent digital shoelace tying machine of the present invention is suitable for processing a raw material strip 81 and a film roll 82 into multiple shoelaces 83 (only one shoelace 83 is shown in the accompanying drawings). The film roll 82 has multiple patterns 821. Each shoelace 83 includes a body portion 831 cut from the raw material strip 81, and two tying heads 832 formed from the film roll 82 and disposed at opposite ends of the body portion 831. The intelligent digital shoelace tying machine includes a machine unit 2, a feeding unit 3, a tying head unit 4, a straightening unit 5, a control unit 6, and a receiving unit 7.

[0031] The machine unit 2 includes a base 21 and a die cutter seat 22 disposed on the top surface of the base 21. The die cutter seat 22 has a processing port 221 extending along an up-down axial direction Z and for the raw material strip 81 to pass through.

[0032] The feeding unit 3 includes a belt roller group 31 arranged on the machine unit 2 and suitable for conveying the raw material belt 81 along a material guide path (not shown), a film feeding group 32 arranged on the machine unit 2 and suitable for conveying the film 82, a feeding drive group 33 for driving the belt roller group 31 and the film feeding group 32, an induction group 34, and an adjustment drive group 35 arranged on the machine unit 2.

[0033] See Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 The strip roller assembly 31 includes a first bracket 311 mounted on the die holder 22, a second bracket 312 spaced apart from the first bracket 311 along a front-to-rear axis Y and extending out of the base 21 along the vertical axis Z, a swing bracket 313 swingable relative to the first bracket 311 at a pivot point 310, a first guide pulley 314 rotatably mounted on the first bracket 311, a second guide pulley 315 rotatably mounted on the second bracket 312, a tension adjustment pulley 316 rotatably mounted on the second bracket 312 along the vertical axis Z, a plurality of steering pulleys 317 rotatably mounted on the first bracket 311 and the second bracket 312 and around which the stock strip 81 is wound, and a thickness sensing wheel 318 rotatably mounted on the swing bracket 313 and adjacent to the first guide pulley 314. The thickness sensing wheel 318 and the first guide pulley 314 are located on opposite sides of the stock strip 81. The tension adjustment wheel 316 is located on the material guide path between the first guide wheel 314 and the second guide wheel 315. When the swing bracket 313 swings relative to the first bracket 311, the thickness sensing wheel 318 is driven to move closer to or away from the first guide wheel 314.

[0034] The raw material tape 81 is fed by a deflection wheel 317 near the second guide pulley 315. After passing the second guide pulley 315 and the tension adjustment wheel 316, it is delivered between the first guide pulley 314 and the thickness sensing wheel 318. After passing the first guide pulley 314, the raw material tape 81 falls naturally and is located within the processing port 221. In this embodiment, the material feeding path is a multi-turn path passing through the deflection wheel 317, the first guide pulley 314, the second guide pulley 315, and the tension adjustment wheel 316.

[0035] See Figure 3 、 Figure 6 and Figure 7 The film feed assembly 32 includes a rubber guide wheel 321 that is driven to rotate and is used to feed the film 82, and a guide member 322 disposed on the base 21. The guide member 322 is a hollow plate and defines a rubber channel 323 extending along the front-to-back axis Y and connected to the processing port 221, and a sensing window 324 that is open along the left-to-right axis X and connected to the rubber channel 323.

[0036] See Figure 2 、 Figure 3 and Figure 6 The feed drive assembly 33 includes a first motor 331 mounted on the first bracket 311 and configured to drive the first guide pulley 314, a second motor 332 mounted on the second bracket 312 and configured to drive the second guide pulley 315, and a rubber motor 333 mounted on the base 21 and configured to drive the rubber guide roller 321. In this embodiment, the first motor 331, the second motor 332, and the rubber motor 333 are stepper motors. Other equivalent components capable of precise control may also be used in other embodiments, without limitation.

[0037] See Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The sensor group 34 includes a thickness sensor 341 provided on the first bracket 311, a pattern sensor 342 movably provided on the machine unit 2 along the front-back axis Y, an upper tension sensor 343 provided on the second bracket 312, a lower tension sensor 344 spaced from the upper tension sensor 343 along the vertical axis Z and provided at a lower end of the second bracket 312, a thickness sensor sheet 345 provided on the top of the swing bracket 313, and an upper and lower sensor sheet 346 provided on the tension adjustment wheel 316 and moving with the tension adjustment wheel 316. Due to the viewing angle, Figure 7 The tension adjustment wheel 316 cannot be seen in FIG.

[0038] By the thickness sensing sheet 345 swinging along with the swing bracket 313 and approaching or moving away from the thickness sensing element 341, the change in the gap between the thickness sensing wheel 318 and the first guide pulley 314 can be detected and a signal can be sent to detect the presence of foreign matter or knots on the raw material belt 81 and send a warning signal or a shutdown signal.

[0039] The pattern sensor 342 is adjacent to the film 82 and corresponds to the sensing window 324. The pattern sensor 342 senses the pattern 821 through the sensing window 324 and sends a signal to control the discharge of the film 82 based on the result of sensing the pattern 821.

[0040] When tension is generated on the web 81 due to the speed difference between the first motor 331 and the second motor 332, the tension adjustment wheel 316 drives the upper and lower sensing plates 346 upward or downward. The upper tension sensor 343 and the lower tension sensor 344 sense the approach or separation of the upper and lower sensing plates 346, further detecting whether the tension adjustment wheel 316 has reached its limit position and sending a signal to adjust the speed of the first motor 331 and the second motor 332.

[0041] The adjustment drive group 35 includes an adjustment seat 23 mounted on the top surface of the base 21, an adjustment motor 351 disposed on the adjustment seat 23, a linkage module 352 connected to the adjustment motor 351 and driven by the adjustment motor 351, and a moving member 353 connected to the linkage module 352 and for the pattern sensing member 342 to be disposed. The adjustment motor 351 is used to drive the linkage module 352 and the moving member 353 to move, so as to link the pattern sensing member 342 to move along the front-back axis Y. The linkage module 352 of this embodiment includes a first pulley 354 rotatably disposed on the adjustment seat 23, a second pulley 355 spaced apart from the first pulley 354 along the left-right axis X, a belt 356 surrounding and linking the first pulley 354 and the second pulley 355, and a threaded rod 357 connected to the second pulley 355 and threadedly connected to the moving member 353. When the size of the pattern 821 changes, the pattern sensing member 342 can be driven by the adjustment drive group 35 to move along the front-to-back axis Y to adjust the position of the pattern 821 when the film 82 is discharged, ensuring that the patterns 821 of different sizes can be located in the appropriate position, so that the complete pattern 821 can be preserved in the part of the film 82 that is expected to be cut.

[0042] See Figure 2 、 Figure 3 、 Figure 6The bundle head unit 4 is connected to the die holder 22 and includes a first knife module 41 and a second knife module 42 movably disposed on the die holder 22 along the left-right axial direction X, a die drive group 43 disposed on the base 21 and used to drive the first knife module 41 and the second knife module 42, a spray group 44 disposed on the base 21 and adjacent to the processing port 221 and used to spray a drug on the film 82, a material removal member 45 movably disposed on the die holder 22 and adjacent to the processing port 221, and an upper clamping jaw 46 and a lower clamping jaw 47 located on opposite sides of the die holder 22 along the vertical axial direction Z. The lower clamping jaw 47 is movable along the left-right axial direction X. The upper clamping jaw 46 and the lower clamping jaw 47 are suitable for clamping the raw material tape 81. The material removal member 45 moves above the processing port 221 along the front-back axial direction Y to remove foreign matter. In this embodiment, the spraying assembly 44 sprays acetone to soften the film 82 .

[0043] The first cutting module 41 and the second cutting module 42 are arranged adjacent to each other along the vertical axis Z. The first cutting module 41 includes a first main cutting die 411 movably disposed along the left-right axis X through one end of the cutting die holder 22, a first auxiliary cutting die 412 movably disposed along the left-right axis X through the other end of the cutting die holder 22, a first stopper 413 disposed on the cutting die holder 22 and facing the first auxiliary cutting die 412, and a resilient member 414 disposed between the first stopper 413 and the first auxiliary cutting die 412. The first auxiliary cutting die 412 includes an abutting portion 415 spaced from the first stopper 413 and for the resilient member 414 to fit over. The second knife module 42 has a second main knife die 421 that is movably provided along the left-right axial direction X at one end of the knife die seat 22, a second auxiliary knife die 422 that is movably provided along the left-right axial direction X at the other end of the knife die seat 22, a second limiting member 423 that is provided on the knife die seat 22 and faces the second auxiliary knife die 422, and a rebound member 424 that is provided between the second limiting member 423 and the second auxiliary knife die 422. The second auxiliary knife die 422 has a stop top 425 that is spaced apart from the second limiting member 423 and on which the rebound member 424 is mounted.

[0044] The cutting die driving group 43 has a driving member 431, an adapter 432 connected to the driving member 431 and driven by the driving member 431, a first connecting member 433 connected to the first main cutting die 411 and movably connected to the adapter 432, a second connecting member 434 connected between the adapter 432 and the second main cutting die 421, and a reset member 435 connected between the first connecting member 433 and the adapter 432.

[0045] The straightening unit 5 includes an air guide 51 positioned below the first guide pulley 314 along the vertical axis Z, and a tape guide 52 positioned below the processing opening 221 along the vertical axis Z. The air guide 51 defines an air guide space 511 through which the raw material tape 81 passes. The air flow blown along the vertical axis Z maintains the raw material tape 81 substantially vertically. The tape guide 52 has a tapered hole therein for guiding the raw material tape 81 to the lower clamping jaw 47.

[0046] The control unit 6 is connected to the feed drive assembly 33, the sensor assembly 34, and the beam head unit 4 via signals, enabling automated and quantifiable operation of the entire system and detecting abnormal conditions during the process. The control unit 6 includes an operation panel 61 for controlling the feed drive assembly 33, the sensor assembly 34, and the beam head unit 4, and a storage module 62 for storing data.

[0047] The material receiving unit 7 includes a material receiving tray 71 , a column 72 extending upward from the material receiving tray 71 along the vertical axis Z, and a plurality of material receiving rods 73 arranged at the top of the column 72 at angular intervals.

[0048] The bundle head unit 4 can be switched between a standby state and a processing state. In the standby state, the resilient members 414 and 424 maintain a distance between the abutting portions 415 and 425 and the first and second limiting members 413 and 423, spacing the first main cutting die 411 and the first auxiliary cutting die 412. The return member 435 constantly applies a biasing force to move the first main cutting die 411 toward the processing opening 221 and the first auxiliary cutting die 412, and spacing the second main cutting die 421 and the second auxiliary cutting die 422. The first and second cutting modules 41 and 42 avoid the raw material strip 81. In the processing state, the first main cutting module 411 moves along the left-right axial direction X and presses against the first auxiliary cutting die 412. The second main cutting module 421 moves along the left-right axial direction X and presses against the second auxiliary cutting die 422, so that the first and second cutting modules 41 and 42 clamp and wrap a portion of the film 82 around the raw material strip 81. Because the first connecting member 433 and the adapter 432 are relatively movable, when the abutting portion 415 of the first secondary cutting die 412 abuts the first stopper 413, the first primary cutting die 411 stops moving, but the second primary cutting die 421 continues to advance a short distance. Therefore, the first cutting module 41 and the second cutting module 42 are offset in the left-right axial direction X to cut the corresponding shoelace 83.

[0049] During operation, the feed drive assembly 33 rotates the first guide pulley 314, the second guide pulley 315, and the rubber guide pulley 321, delivering the raw material tape 81 and the film roll 82 to the processing port 221. Next, the spray assembly 44 sprays acetone to slightly dissolve and soften a portion of the film roll 82. The upper clamp 46 and the lower clamp 47 clamp a predetermined length of the raw material tape 81. The first and second blade modules 41 and 42 then tighten the softened portion of the film roll 82 to the raw material tape 81 and cut it at the tightening point, thereby producing a single shoelace 83. It should be noted that when the film roll 82 is tightened to the tightening point of the raw material tape 81 and cut, two bundle ends 832 are formed simultaneously. One bundle end 832 represents the upper end of the shoelace 83 currently being cut, and the other bundle end 832 represents the lower end of the next shoelace 83 to be cut. Finally, the lower clamping jaw 47 is moved to move the shoelace 83 to one of the receiving rods 73 and then released, so that the shoelace 83 is folded in half and hung on the receiving unit 7. Thus, the processing of one shoelace 83 can be completed.

[0050] Compared to existing technologies, the present invention utilizes the strip roller assembly 31 to allow the raw material strip 81 to be bundled in a naturally drooping, low-tension state, reducing length errors within the strip body 831 and improving yield. Furthermore, the multi-turn material guide path reduces the overall size of the machine, achieving a reduced volume. Furthermore, the control unit 6 and sensor assembly 34 enable automated operation, enabling quantitative and easy adjustment of process parameters. They can also detect abnormalities during the process, further enhancing ease of use.

[0051] More specifically, the control unit 6 allows the user to precisely control the first motor 331, the second motor 332, and the adhesive motor 333, finely adjusting their rotational speeds to control the feed speeds of the stock belt 81 and the film 82. The tension of the stock belt 81 can also be controlled by controlling the speed difference between the first motor 331 and the second motor 332. Furthermore, the control unit 6 can be used in conjunction with the sensor group 34 to detect abnormalities during the process. Based on the signals sent by the sensor group 34, the user can control the associated components, such as making timely adjustments or shutting down the machine in the event of an abnormality. This allows for more flexible configuration of the overall system's operation. Digital control of the feed drive group 33 and the beam head unit 4 through the control unit 6 eliminates the inconvenience of relying solely on the operator's sense and experience in conventional techniques. Due to the digitization of the present invention, all settings and abnormal conditions during the process can be recorded using the storage module. For example, parameters can be recorded for different shoe types or shoelaces of different materials so that they can be directly applied later without having to reset them each time. This is not only convenient for use but also suitable for customized shoelaces. Furthermore, by digitizing the system parameters and various settings, the signals sent by the control unit 6 and the sensor group 34 are easy to read and utilize. For example, they can be sent to the control units of other processes or the administrator's equipment to facilitate other processes or facilitate monitoring at any time. Moreover, if additional components are to be expanded, the digitized information can be directly used. In summary, the present invention's intelligent digital shoelace tying machine can indeed achieve the purpose of this utility model. However, the above description is merely an embodiment of the present utility model and should not be used to limit the scope of implementation of the utility model. All simple equivalent changes and modifications made in accordance with the claims and the content of the specification of the utility model are still within the scope of the present utility model.
