[0001] The present invention relates to a tubular processing device for processing tubular articles. [Background technology]
[0002] BACKGROUND ART Conventionally, as described in Patent Document 1, for example, stretchable coil-shaped articles have been formed into ring shapes and used as various articles such as hair rubber bands and mobile phone straps. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-163812 Summary of the Invention [Problem to be solved by the invention]
[0004] However, such expandable coil rings are prepared as coil-shaped members of a predetermined length, and it is difficult for users to prepare their own coil rings with their preferred design in terms of color, length, etc., much less to create their own coil-shaped members. In particular, when children use coil rings as a toy, for example, it is desirable to be able to create coil-shaped members in a simple manner from tubular members of various designs. An object of the present invention is to provide a tubular article processing device for processing a tubular article so that a user can easily create a coiled article of his or her own design. [Means for solving the problem]
[0005] In order to achieve the above-mentioned object, the tubular object processing device of the present invention is a tubular object processing device that processes tubular objects, and is equipped with a passage that guides the movement of the tubular object and has an entrance into which the tubular object can be inserted and an exit from which the processed tubular object is discharged, a cutting section that cuts the tubular object moving in the passage so that it can be separated into a coil shape, a first feeding section that sends the processed tubular object in the passage to the exit side, and a second feeding section that sends the tubular object in the passage to the cutting section, wherein the first feeding section has a pair of first rollers that sandwich the tubular object therebetween, and the second feeding section has a pair of second rollers that sandwich the tubular object therebetween, and the distance between the pair of first rollers at the position where the pair of first rollers sandwich the tubular object is set to be smaller than the distance between the pair of second rollers at the position where the pair of second rollers sandwich the tubular object.
[0006] Here, "cutting the tubular article so that it can be separated into coils" not only means completely cutting the tubular article into coils and separating it, but also includes a case where the tubular article is cut into coil-shaped slits so that the tubular article is separable but not completely separated. When cutting the tubular article so as to make coil-shaped slits, for example, the user can form a coil-shaped article by cutting and separating the tubular article along the slits when using it.
[0007] In the present invention, preferably, the cutting portion has a cutting blade that separates and cuts the tubular article, and a rotating portion that rotates the cutting blade around the tubular article.
[0008] Preferably, the present invention further comprises an operating portion for rotating the rotating portion.
[0010] Preferably, the present invention further comprises a power transmission unit that transmits power from the operating unit to the rotating unit, the first feeding unit, and the second feeding unit that feeds the tubular articles in the passage to the cutting unit.
[0011] In the present invention, preferably, the first roller includes a first protrusion on its outer periphery, and the second roller includes a second protrusion on its outer periphery, and the distance between the first protrusions of the pair of first rollers is set to be smaller than the distance between the second protrusions of the pair of second rollers.
[0012] In the present invention, preferably, the cutting blade is positioned such that the surface including the cutting blade is perpendicular to the axial direction of the passage and the direction in which the cutting blade extends is radial to the passage, and then rotated toward the outlet by an angle α around the axis of the direction in which the cutting blade extends, and then rotated toward the outlet by an angle β around an axis that passes through the tip of the cutting blade and is perpendicular to the axial direction of the passage and perpendicular to the direction in which the cutting blade extends, and the angle α is set greater than the angle β.
[0013] In the present invention, preferably, the inlet is located above the cut in the vertical direction, and the outlet is located below the cut in the vertical direction.
[0014] Preferably, the present invention further comprises a guide portion for guiding the tubular article after it has been cut so as to be separable in a direction different from the axial direction of the passage. [Effects of the Invention]
[0015] According to the present invention, it is possible to provide a tubular article processing device that processes a tubular article so that a user can easily create a coiled article of their preferred design by themselves. [Brief explanation of the drawings]

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
[0018] Fig. 1 is a perspective view showing the entire tubular article processing apparatus 1 according to one embodiment of the present invention. As shown in Fig. 1, the tubular article processing apparatus 1 has a dome-shaped housing 2, an inlet 4 for a tubular article 100 (see Fig. 13) provided on the top surface of the housing 2, an outlet 6 provided at the lower end of the side surface of the housing 2 for removing the tubular article 100, and an operating unit 8 provided at approximately the center of the side surface of the housing 2 for operating the internal mechanism of the tubular article processing apparatus 1.
[0019] 2 to 4 are views showing the internal mechanism with the housing 2 removed, with Fig. 2 being a perspective view showing the internal mechanism of a tubular article processing apparatus 1 according to one embodiment of the present invention, Fig. 3 being a front view showing the internal mechanism of a tubular article processing apparatus 1 according to one embodiment of the present invention, and Fig. 4 being a side view showing the internal mechanism of a tubular article processing apparatus 1 according to one embodiment of the present invention. As shown in Figs. 1 to 4, the tubular article processing apparatus 1 has a passage 10 that guides the movement of a tubular article 100 and into which the tubular article 100 can be inserted, a cutting section 12 that cuts the tubular article 100 moving in the passage 10 so that it can be separated into a coil shape, a first feeding section 14 that feeds the processed tubular article 100 in the passage to the outlet 6 of the housing 2, a second feeding section 16 that feeds the tubular article 100 that has entered from the inlet 4 to the cutting section 12, and a power transmission section 18 that transmits power from the operating section 8 to the cutting section 12, the first feeding section 14, and the second feeding section 16.
[0020] 1 to 4 is the normal usage configuration in which the mounting portion 20 is placed on a horizontal surface such as the ground or a desk, and is used stably. In this case, the inlet 4 for the tubular article 100 is provided on the upper surface of the cover portion 22, and the outlet 6 is provided at the lower end of the cover portion 22, so that the tubular article 100 moves from the top to the bottom of the tubular article processing apparatus 1.
[0021] The passage 10 is provided with a first cylindrical portion 24 attached to the upper surface of the housing 2, a second cylindrical portion 26 vertically below the first cylindrical portion 24 and protruding upward from the upper surface of the cut portion 12, and a third cylindrical portion 28 extending into the interior of the cut portion 12.
[0022] The first cylindrical portion 24 is attached to the upper surface of the housing 2 and opens to the upper surface of the housing 2. As a result, the upper end of the internal space of the first cylindrical portion 24 forms the entrance 4 of the passage 10. The second cylindrical portion 26 is disposed below the second feed portion 16 at a predetermined distance from the second feed portion 16, and its lower end is fixed to the upper surface of the cutting portion 12. The third cylindrical portion 28 is disposed above the first feed portion 14 at a predetermined distance from the first feed portion 14 and fixed to the cutting portion 12. The upper end of the third cylindrical portion 28 contacts the lower end of the second cylindrical portion 28 inside the cutting portion 12. Therefore, the second cylindrical portion 26 and the third cylindrical portion 28 are provided continuously. The lower end of the third cylindrical portion 28 protrudes downward from the lower surface of the cutting portion 12 and is disposed above the first feed portion 14 at a predetermined distance. The inner diameters of the first cylindrical portion 24, the second cylindrical portion 26, and the third cylindrical portion 28 need only be large enough to allow the tubular object 100 to pass through them, and may be set to an inner diameter that has a certain margin above the expected maximum diameter of the tubular object 100 so that the tubular object 100 can easily pass through.
[0023] A guide section 30 is provided below the first feed section 14 to guide the tubular article 100 cut into a coil shape by the cutting section 12 toward the outlet 6. The guide section 30 has an upper surface that is an approximately rectangular opening 32, and a side surface facing the outlet 6 that is also an rectangular opening 34. The side surface and bottom surface farther from the outlet 6 form a curved surface 36 that is continuous in an arc shape connecting the upper surface opening 32 and the side opening 34.
[0024] Looking at the path taken by the tubular article 100, the internal spaces of the first cylindrical section 24, the second cylindrical section 26, and the third cylindrical section 28, the virtual cylindrical space connecting them, and the virtual cylindrical space from the third cylindrical section 28 below the first feed section 14 and above the guide section 30 form the passage 10 along which the tubular article 100 moves. Therefore, the position directly above the guide section 30 is the exit 5 of the passage 10. In this embodiment, the direction of the axis A of the passage 10 is along the vertical direction. Furthermore, the guide section 30 is provided with a curved surface 36 so as to guide the tubular article 10 in a direction different from the direction of the axis A of the passage 10 when the tubular article 10 processed by the cutting section 12 emerges from the exit 5.
[0025] Fig. 5 is a perspective view showing the cutting unit 12 of the tubular article processing apparatus 1 according to one embodiment of the present invention. As shown in Fig. 5, the cutting unit 12 has a rotating part 38 formed in a hollow disk shape and rotatable around the axis A of the passage 10, and a pair of cutting blades 40 arranged inside the rotating part 38. A third cylindrical portion 28 is integrally formed at the center inside the rotating portion 38. A pair of mounting bases 42 for attaching cutting blades 40 are formed on the outside of the third cylindrical portion 28. The mounting bases 42 are provided on opposite radial sides of the axis A, and have inclined surfaces 44 so that the cutting blades 40 form a predetermined angle with respect to the axis A when attached to the mounting bases 42. The rotating portion 38 is rotatable about the axis A by operation of the operating unit 8 transmitted by the power transmission unit 18. When attached to the mounting base 42, the cutting blade 40 is arranged so that a portion of the cutting blade 40 protrudes into the third cylindrical portion 28 from a notch 46 formed in the third cylindrical portion 28. In this embodiment, the second cylindrical portion 26 and the third cylindrical portion 28 are provided so as to be continuous, and therefore, if the second cylindrical portion 26 and the third cylindrical portion 28 are viewed as a single cylindrical portion, it can also be considered that the cutting blade 40 is arranged so as to protrude into the cylindrical portion from an opening formed in the single cylindrical portion.
[0026] 6 and 7 are diagrams illustrating the installation position of the cutting blade 40 of the tubular article processing apparatus 1 according to one embodiment of the present invention. As shown in FIGS. 6 and 7, when a plane including the cutting blade 40 is arranged perpendicular to the axis A of the passage 10 and the direction X in which the cutting blade 40 extends is arranged radially of the passage 10, the direction perpendicular to the direction X and the axis A is defined as direction Y. From this state, the cutting blade 40 is rotated downward by an angle α around the direction X as shown in FIG. 6. Then, from this state, it is further rotated downward by an angle β around the direction Y as shown in FIG. 7. The cutting blade 40 is arranged at this angular position relative to the passage 10. In this embodiment, the angle α is set to be larger than the angle β, and it is preferable that the angle α is set to 20° to 40° and the angle β is set to 5° to 15°. In this embodiment, the angle α is set to 30° and the angle β is set to 10°.
[0027] As shown in Figures 2 to 4 above, the first feeding section 14 is disposed on the passage 10 between the cutting section 12 and the guide section 30, and has a pair of first rollers 48 disposed on both sides of the passage 10. FIG. 8 is a perspective view showing a first roller 48 of the first feed section 14 of the tubular article processing apparatus 1 according to one embodiment of the present invention, and FIG. 9 is a cross-sectional view showing the first roller 48 of the first feed section 14 of the tubular article processing apparatus 1 according to one embodiment of the present invention. The first roller 48 has a rotating shaft 50, a pair of flanges 52 provided on the rotating shaft 50 at a predetermined interval, and a body portion 54 formed between the pair of flanges 52. The diameter of the body portion 54 is smaller than the diameter of the flanges 52 and smaller than the diameter of the rotating shaft 50. The body portion 54 is formed with a plurality of first protrusions 56 extending from one of the flanges 52 through the body portion 54 to the other flange 52. The first protrusions 56 protrude from the body portion 54 and the flanges 52 in a radial direction or at a predetermined angle relative to the radial direction, and extend at equal intervals around the rotating shaft 50 and parallel to the rotating shaft 50. The cross section of the first protrusions 56 is approximately rectangular or trapezoidal, and its tip is flat. An interlocking gear 58 is integrally formed on each of the rotation shafts 50 of the first rollers 48, and the interlocking gears 58 mesh with each other so that when one first roller 48 rotates, the other first roller 48 rotates in the opposite direction to the first roller 48.
[0028] As shown in Figures 2 to 4 above, the second feeding section 16 is disposed on the passage 10 between the cutting section 12 and the first cylindrical section 24, and has a pair of second rollers 60 disposed on both sides of the passage 10. FIG. 10 is a perspective view showing a second roller 60 of the second feed section 16 of a tubular article processing apparatus 1 according to one embodiment of the present invention, and FIG. 11 is a cross-sectional view showing the second roller 60 of the second feed section 16 of a tubular article processing apparatus 1 according to one embodiment of the present invention. The second roller 60 has a rotating shaft 62, a pair of flanges 64 provided on the rotating shaft 62 at a predetermined interval, and a body portion 66 formed between the pair of flanges 64. The diameter of the body portion 66 is smaller than the diameter of the flanges 64 but larger than the diameter of the rotating shaft 62. The body portion 66 is formed with a plurality of second protrusions 68 protruding radially from the body portion 66. The second protrusions 68 protrude only from the body portion 66 and do not extend in the direction of the rotating shaft 62 to the flanges 64. The second protrusions 68 extend at equal intervals around the rotating shaft 62 and parallel to the rotating shaft 62. The cross section of the second protrusions 68 is approximately triangular, and their tips are pointed. An interlocking gear 70 is integrally formed on each of the rotation shafts 62 of the second rollers 60, and the interlocking gears 70 mesh with each other so that when one second roller 60 rotates, the other second roller 60 rotates in the opposite direction to the one second roller 60.
[0029] FIG. 12 is a longitudinal cross-sectional view of a cylindrical article processing apparatus 1 according to one embodiment of the present invention. Referring to FIG. 12 and the aforementioned FIGS. 8 to 11, the distance D1 between the rotation axes 50 of the first rollers 48 and the distance D2 between the rotation axes 62 of the second rollers 60 are set to be the same. Furthermore, the length L1 of the first protrusions 56 of the first rollers 48 in the direction of the rotation axis 50 is set to be greater than the length L2 of the second protrusions 68 of the second rollers 60 in the direction of the rotation axis 62. The widths W11 and W12 of the tip ends of the first protrusions 56 of the first rollers 48 are set to be greater than the width W2 of the tip ends of the second protrusions 68 of the second rollers 60. The first rollers 48 have a greater number of first protrusions 56 than the second rollers 60. The amount P1 of the first protrusions 56 protruding from the body portion 54 is set to be greater than the amount P2 of the second protrusions 68 protruding from the body portion 66. 9, the protrusion amount P1 is shown as the protrusion amount of the first protrusions 56 having a substantially rectangular cross section, but the protrusion amount P1 is the same for the first protrusions 56 having a substantially trapezoidal cross section. The distance G1 between the tips of the first protrusions 56 of the pair of first rollers 48 is set to be smaller than the distance G2 between the tips of the second protrusions 68 of the pair of second rollers 60.
[0030] As shown in Figures 2 to 4 above, the power transmission unit 18 has a first transmission unit 72 that transmits the rotational power from the operating unit 8 to the cutting unit 12, a second transmission unit 74 that transmits the rotational power from the operating unit 8 to the first feed unit 14, and a third transmission unit 76 that transmits the rotational power from the operating unit 8 to the second feed unit 16 via the first transmission unit 72.
[0031] The first transmission unit 72 has a first bevel gear 80 fixed to the rotating shaft 78 of the operating unit 8, a second bevel gear 82 that meshes with the first bevel gear 80 and is arranged above the rotating unit 38 of the cutting unit 12, internal teeth 84 formed on the inner surface of the second bevel gear 82, a plurality of (three in this embodiment) planetary gears 86 that mesh with the internal teeth 84, and a first gear 88 that meshes with the plurality of planetary gears 86 and is fixed to the second cylindrical unit 26. In this embodiment, in the tubular article processing apparatus 1, the passage 10 is arranged vertically in normal use, so the rotation axis of the rotating unit 38 of the cutting unit 12 is also vertical, and the rotation axis of the second bevel gear 82 also coincides with the axis A of the passage 10. Because the rotation shaft 78 of the operating unit 8 extends horizontally, the rotation axis of the first bevel gear 80 extends in a direction perpendicular to the axis A of the passage 10.
[0032] The second transmission unit 74 has a second gear 89 fixed to the rotation shaft 78 of the operating unit 8 closer to the tip than the first bevel gear 80, and a third gear 90 that meshes with the second gear 89 and is fixed to one of the rotation shafts 50 of the pair of first rollers 48. The third transmission part 76 has a third bevel gear 92 fixed above the first gear 88 in the second cylindrical part 26, a fourth bevel gear 96 meshed with the third bevel gear 92 and arranged so that its rotation axis 94 is perpendicular to the axis A, a fourth gear 98 fixed coaxially with the fourth bevel gear 96, and a fifth gear 99 meshed with the fourth gear 98 and fixed to one of the rotation axes 62 of a pair of second rollers 60. The gears of the power transmission unit 18, except for the second bevel gear 82 and the planetary gear 86, have their rotation shafts rotatably supported by a support unit (not shown).
[0033] The rotating shaft 78 of the operating unit 8 has a first rotating shaft 78A to which a first bevel gear 80 and a second gear 89 are fixed, and a second rotating shaft 78B to which the operating unit 8 is fixed, located closer to the operating unit 8 than the first rotating shaft 78A. The end of the second rotating shaft 78B is inserted into the end of the first rotating shaft 78A. A pair of cylindrical portions 75A, 75B having axial teeth that mesh with each other are provided at the end of the first rotating shaft 78A on the second rotating shaft 78B side and the end of the second rotating shaft 78B on the first rotating shaft 78A side, respectively. The cylindrical portion 75A on the first rotating shaft 78A side is fixed to the first rotating shaft 78A. On the other hand, the cylindrical portion 75B of the second rotating shaft 78B is axially slidable relative to the second rotating shaft 78B but is unable to rotate relative to the second rotating shaft 78B. A spring 79 is provided between the cylindrical portion 75B and the operating portion 8, and biases the cylindrical portion 75B toward the cylindrical portion 75A.
[0034] The cylindrical article processing apparatus 1 of this embodiment configured as described above operates as follows. 13 is a diagram illustrating the operation of a tubular article processing apparatus 1 according to one embodiment of the present invention. A tubular article 100 is inserted into the first cylindrical portion 24 through the inlet 4. When the operating unit 8 is then rotated by hand, rotational power is transmitted to the first bevel gear 80 via the cylindrical portions 75B and 75A. This rotational power is converted into rotational power in an orthogonal direction by the second bevel gear 82, and then transmitted to the first gear 88 via the internal gears 84 and the planetary gear 86. The first gear 88 is fixed to the second cylindrical portion 26, and therefore rotates the second cylindrical portion 26. At this time, the rotational direction of the second cylindrical portion 26 is opposite to the rotational direction of the second bevel gear 82.
[0035] When the third bevel gear 92 rotates due to the rotation of the second cylindrical portion 26, this rotation is converted into rotational power in a perpendicular direction by the fourth bevel gear 96, rotating the fourth gear 98, which is fixed coaxially with the fourth bevel gear 96. The fourth gear 89 meshes with the fifth gear 99, which is fixed to one of the rotation shafts 62 of the second rollers 60, and rotates the fifth gear 99. This causes one of the second rollers 60 to rotate. Here, since one of the second rollers 60 meshes with the other second roller 60 via the interlocking gear 70, when one of the second rollers 60 rotates, the other second roller 60 rotates in the opposite direction. When the pair of second rollers 60 rotate, the second protrusions 68 sandwich the tubular object 100 inserted therebetween and move it downward. In this way, the tubular object 100 is sent to the cutting section 12 by the second rollers 60.
[0036] The tubular article 100 that has passed between the second rollers 60 is inserted into the rotating second cylindrical portion 26, and then further into the third cylindrical portion 28 within the rotating portion 38 of the cutting section 12. Here, the second cylindrical portion 26 is fixed to the rotating portion 38, so the rotating portion 38 also rotates as the second cylindrical portion 26 rotates. Two cutting blades 40 protrude from the outer periphery of the third cylindrical portion 28, so as the tubular article 100 is sent downward by the second rollers 60, the cutting blades 40 rotate and cut the tubular article 100. By this action, the tubular article 100 is cut into a spiral or coil shape.
[0037] The cut tubular article 100 exits the third cylindrical section 28. Here, the rotational power from the operating section 8 is transmitted to the second gear 89. The second gear 89 is engaged with the third gear 90 fixed to the rotation shaft 50 of one of the first rollers 48, so that when one of the first rollers 48 rotates, the other first roller 48 rotates in the opposite direction. When the pair of first rollers 48 rotate, the first protrusions 56 pinch the tubular article 100 passing between them and move it downward. The tubular article 100 cut into a coil in this way is sent to the outlet 5 by the first roller 48. In addition, the first roller 48 has the function of sending the tubular object 100 cut into a coil shape to the exit 5, and also has the role of pulling the tubular object 100 toward the cutting portion 12 from the opposite side of the cutting portion 12 relative to the second roller 60.
[0038] The tubular article 100 cut into a coil enters the guide section 30. A curved surface 36 is formed in the guide section 30, so that the tubular article 100 changes direction along the curved surface 36 from the vertical direction, which is the axis A of the passage 10, to a horizontal direction perpendicular to the vertical direction. The tubular article 100, now turned around, comes out of the outlet 6 of the housing 2. The user takes out the tubular article 100 that has come out of the outlet 6. In this embodiment, the tubular article 100 taken out of the housing 2 has been completely cut into a coil shape and separated (separated), so the user unwinds the tubular article 100 to create two coiled articles.
[0039] For example, if a large load is placed on power transmission unit 18 due to some malfunction, such as tubular article 100 getting stuck midway, cylindrical portion 75B will have difficulty turning even when operating unit 8 is rotated, and the rotational force of cylindrical portion 75B will overcome the biasing force of spring 79, causing cylindrical portion 75B to slide toward operating unit 8 and no longer mesh with cylindrical portion 75A, and the rotation of operating unit 8 will no longer be transmitted to power transmission unit 18. By preventing the transmission of rotational power from operating unit 8 with this structure using cylinders 75A, 75B and spring 79, internal mechanisms such as power transmission mechanism 18 will be prevented from being damaged by operating operating unit 8.
[0040] According to this embodiment configured as above, the following excellent effects can be obtained. The tubular article processing device 1 is equipped with a passage 10, a cutting unit 12, and a first feeding unit 14, so that the cutting unit 12 can cut the tubular article 100 moving in the passage 10 into a coil shape. This allows a coiled article to be created from the cut tubular article 100. A user can select a tubular article 100 of their preferred color, pattern, and length, and easily create a coiled article themselves.
[0041] Furthermore, since the first feeding section 14 can feed the tubular articles 100 toward the exit 5, the tubular articles 100 do not get clogged in the passage 10 and are smoothly discharged from the outlet 6. By feeding the cut tubular articles 100 toward the exit 5, the first feeding section 14 also plays a role in pulling the uncut tubular articles 100 from the exit 5 side and feeding them to the cutting section 12, thereby preventing problems such as the tubular articles 100 getting clogged in the cutting section 12.
[0042] Because the cutting section 12 has a cutting blade 40 and a rotating section 38 that rotates the cutting blade 40, the cutting blade 40 cuts the tubular object 100 moving through the passage while rotating around the tubular object 100, thereby cutting the tubular object 100 into a coil shape. Since the tubular object 100 is not rotated relative to the cutting blade 40 but is rotated relative to the tubular object 100 by the rotating section 38, the tubular object 100 can be cut into a coil shape with a simple structure without having to provide a mechanism for moving the tubular object 100 in a coil shape within the passage 10 or complicate the mechanism.
[0043] The tubular article processing device 1 has an operating unit 8, and the user operates the operating unit 8 to rotate the rotating unit 38, so that the tubular article 100 can be cut into a coil shape with a simple operation. In addition, because the user actually operates the device to cut the tubular article 100, the user can get a sense of actually processing the tubular article 100, and the user can enjoy processing the tubular article 100.
[0044] Since the second feeding section 16 is provided, the tubular object 100 can be fed to the cutting section 12 by the second feeding section 16. This prevents problems such as the tubular object 100 not being able to enter the cutting section 12 and being unable to cut the tubular object 100 properly, and allows the tubular object 100 to be cut reliably.
[0045] The power transmission unit 18 transmits power from the operating unit 8 to the rotating unit 38, the first feed unit 14, and the second feed unit 16, so that the rotating unit 38, the first feed unit 14, and the second feed unit 16 can be operated simultaneously and easily by operating one operating unit 8. In this embodiment, the power transmission unit 18 transmits power using gears, so that the operations of the rotating unit 38, the first feed unit 14, and the second feed unit 16 can be linked and operated, and the desired operation can be reliably performed by linking each mechanism.
[0046] Since the first feed section 14 has a first roller 48 and the second feed section 16 has a second roller 60, the tubular object 100 can be fed downstream on both the upstream and downstream sides of the cutting section 12, thereby preventing problems such as the tubular object 100 getting stuck in the passage 10 and ensuring that the tubular object 100 is fed downstream.
[0047] A first protrusion 56 is formed on the first roller 48, and a second protrusion 68 is formed on the second roller 60, with the first protrusions 56 and the second protrusions 68 being arranged under different conditions. Specifically, the distance G1 between the first protrusions 56 on the pair of first rollers 48 is set to be smaller than the distance G2 between the second protrusions 68 on the pair of second rollers 60. Here, the first roller 48 sends the tubular article 100 after it has been cut into a coil to the exit 5, while the second roller 60 sends the tubular article 100 before it is cut into a coil to the cutting section 12. Therefore, the tubular article 100 sandwiched between the first rollers 48 is more flexible (more easily deformed) than the tubular article 100 sandwiched between the second rollers 60. In this embodiment, the distance G1 between the first protrusions 56 of the first roller 48 is set to be smaller than the distance G2 between the second protrusions 68 of the second roller 60, so that the flexible tubular article 100 cut into a coil can be reliably clamped between the first protrusions 56 of the first roller 48, which have a small distance G1 between them, and the uncut tubular article 100 can be reliably clamped between the second protrusions 68 of the second roller 60, which have a large distance G2 between them, without being excessively crushed. This allows the tubular article 100 to be moved smoothly and reliably both before and after being cut into a coil.
[0048] The cutting blade 40 is rotated by angle α toward the outlet 5 around an axis corresponding to the direction X in which the cutting blade 40 extends, and is positioned at a position rotated by angle β toward the outlet 5 around an axis corresponding to a direction Y that passes through the tip of the cutting blade 40, is perpendicular to the axial direction A of the passage 10, and is perpendicular to the direction in which the cutting blade 40 extends, and the angle α is set to be larger than the angle β. This allows the cutting blade 40 to be positioned at an appropriate angle with respect to the axial direction A of the passage 10, and the tubular article 100 moving through the passage 10 can be well cut into a coil shape without being jammed in the passage 10 without being cut by the cutting blade 40 or twisting the tubular article 100.
[0049] When the tubular article processing device 1 is placed in a stable usage position, the passage 10 is arranged vertically, the inlet 4 is located vertically above the cutting portion 12, and the outlet 5 is located vertically below the cutting portion 12. This makes it easier for the tubular article 100 to move within the passage 10, preventing problems such as the tubular article 100 getting stuck in the passage 10, and ensuring that the tubular article 100 is cut into a coil shape.
[0050] Since the guide section 30 is provided downstream of the passage 10, the cut tubular object 100 can be moved by the guide section 30 in a direction different from the axial direction A of the passage 10. As a result, when the tubular object 100 is cut by the cutting section 12, the passage 10 is positioned vertically, and when the cut tubular object 100 is to be removed, it can be removed from the removal opening 6 provided on the side of the cover section 22 of the housing 2, allowing the user to easily remove the tubular object 100. Furthermore, since the tubular object 100 after cutting is guided by the guide section 30 in a horizontal direction different from the axial direction A of the passage 10, there is no need to secure space in the axial direction A of the passage 10 for moving the tubular object 100 that has come out of the exit 5 of the passage 10.As a result, the dimension from the apex of the cover section 22 of the tubular object processing device 1 to the loading section 20 can be reduced, which contributes to the miniaturization of the tubular object processing device 1.
[0051] The second protrusions 68 serve to pinch the tubular object 100 that has not been cut in a spiral shape and feed it toward the cutting section 12. At this time, the tubular object 100 is not yet cut by the cutting section 12, and is therefore less likely to deform. Furthermore, when the tubular object 100 is cut by the cutting section 12, if the resistance from the second roller 60 is large, the tubular object 100 cannot be cut well. Therefore, in this embodiment, the protrusion amount P2 of the second protrusions 68 is set smaller than the protrusion amount P1 of the first protrusions 56 on the outlet 5 side, and the distance G2 between the tips of the second protrusions 68 is set larger than the distance G1 between the tips of the first protrusions 56 on the outlet 5 side. This allows the tubular object 100 to be pinched by the second protrusions 68, and if the resistance at the cutting section 12 is large, the tubular object 100 can slide on the second protrusions 68 as necessary. This makes it easier to feed the tubular object 100 and cut the tubular object 100 by the cutting section 12.
[0052] The first protrusions 56 serve to forcibly discharge the tubular article 100 toward the outlet 5. At this time, since the tubular article 100 is easily deformed because it has been spirally cut by the cutting blades 40, the protrusion amount P1 of the first protrusions 56 is set to be greater than the protrusion amount P2 of the second protrusions 68 on the entrance 4 side, and the distance G2 between the tips of the first protrusions 56 is set to be smaller than the distance G2 between the tips of the second protrusions 68, thereby making it easier to reliably grasp the tubular article 100 and send it toward the outlet 5.
[0053] The widths W11, W12 of the tip of the first protrusion 56 are set larger than the width W2 of the tip of the second protrusion 68. Therefore, the area of the tip of the first protrusion 56 is larger than the area of the tip of the second protrusion 68, and the contact area between the first protrusion 56 and the tubular article 100 is larger. This makes it possible to increase the frictional force between the first protrusion 56 and the tubular article 100 compared to the second protrusion 68, and the first protrusion 56 can more reliably send the tubular article 100 toward the exit 5. Note that the length L1 of the tip of the first protrusion 56 is larger than the length L2 of the tip of the second protrusion 68, which also contributes to increasing the contact area between the first protrusion 56 and the tubular article 100.
[0054] Since the second transmission unit 74 has a second gear 89 fixed to the rotation shaft 78 of the operating unit 8 and a third gear 90 fixed to one of the rotation shafts 50 of the first roller 48, the rotation of the operating unit 8 is directly transmitted to the first roller 48. Here, the first roller 48 has the function of discharging the spirally cut tubular article 100 toward the exit 5, but after the tubular article 100 is spirally cut and its downstream end is released from the second roller 68, the first roller 48 alone pulls the tubular article 100 that has not yet been cut toward the cutting section 12 and sends the tubular article 100 that has already been cut toward the exit 5. In this embodiment, the transmission mechanism of the second transmission unit 74 is composed of few components and is configured so that the rotation of the operating unit 8 is directly transmitted to the first roller 48. Therefore, the rotational force from the operating unit 8 can be transmitted well to the first roller 48, and the rotational force required for the first roller 48 can be obtained with less force.
[0055] The present invention is not limited to the above-described embodiment, and may be embodied in the following manner, for example. In the above-described embodiment, the tubular article 100 is cut into a coil shape by the cutting blade 40 and completely separated, but this is not limited thereto. For example, the cutting blade 40 may make a slit in part of the thickness of the tubular article 100, cutting the tubular article 100 so that part or all of the tubular article 100 remains unseparated. Such a cutting method is also included in the "cutting into a coil" in the present invention. If the tubular article 100 is not completely separated, a user may manually separate the tubular article into coils along the slit, or a post-processing device may be provided to automatically separate the tubular article. In short, the cutting portion may be any portion that can cut the tubular article into coils so that the tubular article can be separated into coils.
[0056] In the above-described embodiment, the direction of the passage was vertical in the stable use position, but it is not limited to this and may be horizontal, diagonal, or vertical from bottom to top, or may be curved as long as it allows tubular items to move. In the above-described embodiment, the operating unit is operated manually by the user to drive the rotating unit, but the present invention is not limited to this, and the operating unit may be operated to automatically drive the rotating unit using the driving force of a motor, etc. In this case, the operating unit may be provided as, for example, a switch for switching the motor, etc., on and off.
[0057] In the above-described embodiment, the tubular article cut into a coil shape is guided in a direction different from the passage by the guide portion, but the guide portion does not necessarily have to be provided. In the above-described embodiment, the cutting blade was defined at predetermined angles α and β relative to the tubular object, but this is not limited to this, and the installation position of the cutting blade relative to the tubular object can be set arbitrarily taking into consideration various conditions such as the shape and material of the tubular object, and the moving speed of the tubular object. In the above-described embodiment, the distance between the first protrusions of a pair of first rollers was set to be smaller than the distance between the second protrusions of a pair of second rollers, but this is not limited to this, and the shape of each roller, the distance between the rollers, the presence or absence of protrusions, the shape of the protrusions, the dimensions of the protrusions, etc. can be set arbitrarily depending on the material and dimensions of the tubular object.
[0058] In the above-described embodiment, the power transmission unit transmitted power from the operating unit to the rotating unit, the first feed unit, and the second feed unit, but this is not limited to this and may, for example, transmit power only to the rotating unit, only to the first feed unit, or only to the second feed unit, as long as it transmits power to at least one of these mechanisms. In the above-described embodiment, the cutting blade rotates around the tubular object by the rotating part to cut the tubular object into a coil shape, but this is not limited to this, and the tubular object may be cut, for example, by rotating the tubular object and fixing the cutting blade.
