[0030] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 . An embodiment of the intelligent digital shoelace tying machine of the present invention is applicable to processing a raw material tape 81 and a film 82 into a plurality of shoelaces 83 (only one shoelace 83 is drawn in the drawings). The film 82 has a plurality of patterns 821. Each of the shoelaces 83 includes a tape body part 831 cut from the raw material tape 81, and two tying head parts 832 respectively arranged at opposite ends of the tape body part 831 and made of the film 82. The intelligent digital shoelace tying machine includes a machine platform 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 holder 22 disposed on the top surface of the base 21. The die holder 22 has a processing opening 221 extending along an up-and-down axis Z and through which the raw material tape 81 passes.

[0032] The feeding unit 3 includes a tape roller group 31 disposed on the machine unit 2 and adapted to convey the raw material tape 81 along a feeding path (not shown in the figure), a film feeding group 32 disposed on the machine unit 2 and adapted to convey the film 82, a feeding driving group 33 for driving the tape roller group 31 and the film feeding group 32, an induction group 34, and an adjustment driving group 35 disposed on the machine unit 2.

[0033] Referring to Figure 2 , Figure 3 , Figure 6 , Figure 7 , the tape roller group 31 has a first bracket 311 disposed on the die holder 22, a second bracket 312 spaced from the first bracket 311 along a front-and-back axis Y and passing through the base 21 along the up-and-down axis Z, a swing bracket 313 swingable relative to the first bracket 311 about a pivot point 310, a first guide pulley 314 rotatably disposed on the first bracket 311, a second guide pulley 315 rotatably disposed on the second bracket 312, a tension adjustment pulley 316 movably and rotatably disposed on the second bracket 312 along the up-and-down axis Z, a plurality of turning pulleys 317 rotatably disposed on the first bracket 311 and the second bracket 312 and around which the raw material tape 81 is wound, and a thickness induction pulley 318 rotatably disposed on the swing bracket 313 and adjacent to the first guide pulley 314. The thickness induction pulley 318 and the first guide pulley 314 are located on opposite sides of the raw material tape 81. The tension adjustment pulley 316 is located between the first guide pulley 314 and the second guide pulley 315 on the feeding path. When the swing bracket 313 swings relative to the first bracket 311, it drives the thickness induction pulley 318 to approach or move away from the first guide pulley 314.

[0034] The raw material tape 81 is fed into the turning pulley 317 near the second guide pulley 315, and after passing around the second guide pulley 315 and the tension adjustment pulley 316, it is sent out between the first guide pulley 314 and the thickness induction pulley 318. After passing through the first guide pulley 314, the raw material tape 81 substantially hangs naturally and is located within the processing opening 221. In this embodiment, the feeding path is a multi-turning path passing through the turning pulley 317, the first guide pulley 314, the second guide pulley 315, and the tension adjustment pulley 316.

[0035] Refer to Figure 3 、 Figure 6 and Figure 7 As shown in FIGS.

[0036] Refer to Figure 2 、 Figure 3 and Figure 6 The film feeding group 32 has a film guiding wheel 321 that can be driven to rotate and is used to convey the film 82, and a guiding member 322 disposed on the base 21. The guiding member 322 is a hollow plate and defines a rubber material channel 323 that extends along the front-rear axial direction Y and communicates with the processing port 221, and a sensing window 324 that opens along a left-right axial direction X and communicates with the rubber material channel 323.

[0037] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The feeding drive group 33 has a first motor 331 disposed on the first bracket 311 and used to drive the first guide pulley 314, a second motor 332 disposed on the second bracket 312 and used to drive the second guide pulley 315, and a rubber material motor 333 disposed on the base 21 and used to drive the film guiding wheel 321. In this embodiment, the first motor 331, the second motor 332, and the rubber material motor 333 are stepping motors. In other embodiments, other equivalent components that can be precisely controlled can also be selected, and it is not limited thereto.

[0037] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The sensing group 34 has a thickness sensor 341 disposed on the first bracket 311, a pattern sensor 342 movably disposed along the front-rear axial direction Y on the machine unit 2, a tension upper sensor 343 disposed on the second bracket 312, a tension lower sensor 344 disposed at a lower end of the second bracket 312 at an interval from the tension upper sensor 343 along the up-down axial direction Z, a thickness sensing sheet 345 disposed on the top of the swing bracket 313, and an up-down sensing sheet 346 disposed on the tension adjusting pulley 316 and moving with the tension adjusting pulley 316. Limited by the viewing angle, the tension adjusting pulley 316 cannot be seen in Figure 7 FIG.

[0038] As the thickness sensing sheet 345 swings with the swing bracket 313 and approaches or moves away from the thickness sensor 341, the change in the gap between the thickness sensing wheel 318 and the first guide pulley 314 can be detected and a signal is sent out to detect an abnormality such as a foreign object or a knot on the raw material tape 81 and send out a warning signal or a stop signal.

[0039] The pattern sensor 342 is adjacent to the film 82 and is positioned corresponding to the sensing window 324. The pattern sensor 342 senses the pattern 821 through the sensing window 324, and then sends a signal according to the result of sensing the pattern 821 to control the discharging of the film 82.

[0040] When the raw material belt 81 generates tension due to the rotational speed difference between the first motor 331 and the second motor 332, the tension adjustment wheel 316 drives the upper and lower sensing pieces 346 to rise or fall together. The upper tension sensor 343 and the lower tension sensor 344 are used to sense the approach or separation of the upper and lower sensing pieces 346, and further detect whether the tension adjustment wheel 316 reaches the limit position, so as to send a signal to adjust the rotational speeds of the first motor 331 and the second motor 332.

[0041] The adjustment driving group 35 has an adjustment base 23 mounted on the top surface of the base 21, an adjustment motor 351 disposed on the adjustment base 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 mounting the pattern sensor 342. The adjustment motor 351 is used to drive the linkage module 352 and the moving member 353 to move, so as to drive the pattern sensor 342 to move along the front-back axis Y. In this embodiment, the linkage module 352 has a first pulley 354 rotatably disposed on the adjustment base 23, a second pulley 355 spaced from the first pulley 354 along the left-right axis X, a belt 356 wound around 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 adjustment driving group 35 can be used to drive the pattern sensor 342 to move along the front-back axis Y, so as to adjust the position of the pattern 821 when the film 82 is discharged, ensuring that patterns 821 of different sizes can be located at appropriate positions, so that the complete pattern 821 can be retained in the portion of the film 82 to be cut as expected.

[0042] Refer to Figure 2 、 Figure 3 、 Figure 6, the beam head unit 4 is connected to the die holder 22, and includes a first die module 41 and a second die module 42 that are movably arranged on the die holder 22 along the left - right axis X, a die driving group 43 arranged on the base 21 and used to drive the first die module 41 and the second die module 42, a spraying group 44 arranged on the base 21 and adjacent to the processing port 221 and used to spray chemicals on the film 82, a material pusher 45 that is movably arranged 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 up - down axis Z. The lower clamping jaw 47 is movable along the left - right axis X. The upper clamping jaw 46 and the lower clamping jaw 47 are adapted to clamp the raw material belt 81. The material pusher 45 moves along the front - back axis Y above the processing port 221 to remove foreign objects. In this embodiment, the spraying group 44 sprays acetone to soften the film 82.

[0043] The first die module 41 and the second die module 42 are arranged adjacent to each other along the up - down axis Z. The first die module 41 has a first main die 411 that is movably inserted through one end of the die holder 22 along the left - right axis X, a first auxiliary die 412 that is movably inserted through the other end of the die holder 22 along the left - right axis X, a first limiting member 413 arranged on the die holder 22 and facing the first auxiliary die 412, and a resilient member 414 arranged between the first limiting member 413 and the first auxiliary die 412. The first auxiliary die 412 has a top - resisting portion 415 that is spaced from the first limiting member 413 and for the resilient member 414 to be sleeved thereon. The second die module 42 has a second main die 421 that is movably inserted through one end of the die holder 22 along the left - right axis X, a second auxiliary die 422 that is movably inserted through the other end of the die holder 22 along the left - right axis X, a second limiting member 423 arranged on the die holder 22 and facing the second auxiliary die 422, and a resilient member 424 arranged between the second limiting member 423 and the second auxiliary die 422. The second auxiliary die 422 has a top - resisting portion 425 that is spaced from the second limiting member 423 and for the resilient member 424 to be sleeved thereon.

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

[0045] The guiding unit 5 includes an air guiding member 51 located below the first guiding pulley 314 along the up-and-down axial direction Z, and a guiding belt member 52 located below the processing port 221 along the up-and-down axial direction Z. The air guiding member 51 defines an air guiding space 511 for the raw material belt 81 to pass through. The raw material belt 81 is substantially kept vertical by the airflow blown along the up-and-down axial direction Z. The guiding belt member 52 has a tapered hole inside for guiding the raw material belt 81 to the lower clamping jaw 47.

[0046] The control unit 6 is signal-connected to the feeding drive group 33, the sensing group 34, and the beam head unit 4, so that the whole can operate automatically and quantitatively, and can detect abnormal conditions during the process. The control unit 6 includes an operation panel 61 for operating to control the feeding drive group 33, the sensing group 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 along the up-and-down axial direction Z from the material receiving tray 71, and a plurality of material receiving rods 73 arranged at the top of the column 72 at angular intervals.

[0048] The beam head unit 4 can be switched between a standby state and a processing state. In the standby state, the resilient members 414 and 424 keep the abutting tops 415 and 425 spaced from the first limiting member 413 and the second limiting member 423, the first main die 411 is spaced from the first sub-die 412, the reset member 435 constantly provides a biasing force to move the first main die 411 toward the processing port 221 and the first sub-die 412, and the second main die 421 is spaced from the second sub-die 422, and the first die module 41 and the second die module 42 avoid the raw material belt 81. In the processing state, the first main die 411 moves along the left-and-right axial direction X and abuts against the first sub-die 412, the second main die 421 moves along the left-and-right axial direction X and abuts against the second sub-die 422, so that the first die module 41 and the second die module 42 clamp and wrap a part of the film 82 around the raw material belt 81. Since the first connecting member 433 and the adapter 432 can move relative to each other, when the abutting top 415 of the first sub-die 412 abuts against the first limiting member 413, the first main die 411 stops moving, but the second main die 421 continues to move forward a small distance. Therefore, the first die module 41 and the second die module 42 are misaligned in the left-and-right axial direction X to cut out the corresponding shoelaces 83.

[0049] During operation, the feeding drive group 33 drives the first guide pulley 314, the second guide pulley 315 and the glue guide pulley 321 to rotate, and feeds the raw material tape 81 and the film 82 to the processing port 221. Then, the spraying group 44 sprays acetone to slightly dissolve and soften the surface of a part of the film 82. The upper clamp 46 and the lower clamp 47 clamp a predetermined length of the raw material tape 81, and then the first knife module 41 and the second knife module 42 tighten the softened part of the film 82 on the raw material tape 81 and cut it at the tightened part to cut out a shoelace 83. It should be noted that when the film 82 is cut at the tightened part where it is tightened on the raw material tape 81, two bundling heads 832 will be formed at the same time. One of the bundling heads 832 is the upper end of the shoelace 83 cut this time, and the other bundling head 832 is the lower end of the next shoelace 83 to be cut. Finally, the lower clamp 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 and hung on the receiving unit 7. Thus, the processing of one shoelace 83 can be completed.

[0050] Compared with the prior art, the present invention uses the strip roller group 31 to perform the bundling head processing on the raw material tape 81 in a low-tension state of natural drooping, reducing the length error of the strip body part 831 and achieving the effect of improving the yield. Through the multi-turn guiding path, the overall size of the machine is reduced, achieving the effect of reducing the volume. In addition, through the control unit 6 and the sensing group 34, the whole can operate automatically, can be quantified and is easy to adjust the process parameters, and can also detect abnormal conditions during the process, further achieving the effect of being convenient to use.

[0051] More specifically, through the control unit 6, the user can precisely control the first motor 331, the second motor 332, and the rubber material motor 333, and can finely control their rotational speeds to control the conveying speeds of the raw material belt 81 and the film 82. The rotational speed difference between the first motor 331 and the second motor 332 can also be controlled to control the tension of the raw material belt 81. In addition, the control unit 6 can also cooperate with the induction group 34 to detect abnormal conditions during the process, and control the corresponding components according to the signals sent by the induction group 34, such as adjusting the movement in a timely manner, or stopping the machine immediately when an abnormal condition occurs, so that the setting of the overall system operation can be more flexible. By controlling the feeding drive group 33 and the beam head unit 4 through the control unit 6 to achieve digitization, it is more convenient compared to the inconvenience caused by only relying on the operator's feeling and experience to adjust in the prior art. Due to digitization in the present invention, the settings and abnormal conditions during the process can be recorded using the storage module. For example, parameters can be recorded separately for different shoe models or shoelaces of different materials for direct application in the future without the need for re-setting each time, which is not only convenient to use but also applicable to customized shoelaces. Further, through the digitization of system parameters and various settings, the signals sent by the control unit 6 and the induction group 34 are easy to read and then utilized. For example, they can be sent to the control unit of other processes or the equipment of the manager for other processes or for convenient monitoring at any time. And if other components need to be expanded, the digitized information can be directly utilized. In summary, the intelligent digital shoelace beam head machine of the present invention can indeed achieve the purpose of the present invention. However, the above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope covered by the present invention.
