[0037] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0038] Figure 1 1 is a perspective view showing the entirety of a cylindrical article processing device 1 according to an embodiment of the present invention. Figure 1 As shown, the cylindrical article processing device 1 comprises a dome-shaped housing 2, a cylindrical article 100 (see Fig.13 ), an outlet 6 provided at the lower end of the side surface of the shell body 2 and used to take out the tubular article 100, and an operating portion 8 provided at approximately the center of the side surface of the shell body 2 and used to operate the internal mechanism of the tubular article processing device 1.

[0039] in addition, Figure 2 to Figure 4 This is a diagram showing the internal mechanism with the housing 2 removed. Figure 2 1 is a perspective view showing the internal mechanism of a cylindrical article processing device 1 according to one embodiment of the present invention. Figure 3 1 is a front view showing the internal mechanism of a cylindrical article processing device 1 according to one embodiment of the present invention. Figure 4 This is a side view showing the internal mechanism of the cylindrical article processing device 1 according to one embodiment of the present invention. Figures 1 to 4 As shown, the cylindrical article processing device 1 has a passage 10 that guides the movement of the cylindrical article 100 and allows the cylindrical article 100 to be inserted, a cutting portion 12 that cuts the cylindrical article 100 moving in the passage 10 into a coil shape that can be separated, a first conveying portion 14 that conveys the processed cylindrical article 100 in the passage to the removal port 6 side of the shell 2, a second conveying portion 16 that conveys the cylindrical article 100 entering from the inlet 4 to the cutting portion 12, and a power transmission portion 18 that transmits power from the operating portion 8 to the cutting portion 12, the first conveying portion 14 and the second conveying portion 16.

[0040] The housing 2 includes a mounting portion 20 having a flat bottom surface and a dome-shaped cover portion 22 mounted on the upper surface of the mounting portion 20. Figures 1 to 4The configuration shown is a common configuration for stable use by placing the placing portion 20 on a horizontal surface such as the ground or a table. At this time, the inlet 4 of 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 downward from the upper side of the tubular article processing device 1.

[0041] The passage 10 is provided with a first cylindrical portion 24 mounted on the upper surface of the housing 2 , a second cylindrical portion 26 provided vertically below the first cylindrical portion 24 to protrude upward from the upper surface of the cutting portion 12 , and a third cylindrical portion 28 extending into the interior of the cutting portion 12 .

[0042] The first cylindrical portion 24 is mounted on the upper surface of the housing 2 and is open in the upper surface of the housing 2. Thus, the upper end of the internal space of the first cylindrical portion 24 becomes the entrance 4 of the passage 10. The second cylindrical portion 26 is arranged below the second conveying portion 16 so as to be spaced a predetermined distance from the second conveying portion 16, and the lower end of the second cylindrical portion 26 is fixed to the upper surface of the cutting portion 12. The third cylindrical portion 28 is arranged above the first conveying portion 14 so as to be spaced a predetermined distance from the first conveying portion 14 and is 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 continuously provided. The lower end of the third cylindrical portion 28 is arranged so as to protrude from the lower surface of the cutting portion 12 and extend downward, and is spaced a predetermined distance from the first conveying portion 14 above the first conveying portion 14.

[0043] The inner diameters of the first cylindrical portion 24, the second cylindrical portion 26, and the third cylindrical portion 28 only need to be large enough for the tubular article 100 to pass through. To facilitate the passage of the tubular article 100, the inner diameters may be set to have a margin of a predetermined size relative to the assumed maximum diameter of the tubular article 100.

[0044] A guide portion 30 is provided below the first conveying portion 14 to guide the tubular article 100 cut into a coil shape by the cutting portion 12 toward the removal port 6. The upper surface of the guide portion 30 is an upper surface opening portion 32 opened in a substantially rectangular shape, and the side surface opposite to the removal port 6 is also a side surface opening portion 34 opened in a rectangular shape. The side surface and the bottom surface away from the removal port 6 are curved surfaces 36 that are continuous in an arc shape in a manner connecting the upper surface opening portion 32 and the side surface opening portion 34.

[0045] If confirm the path that the tubular article 100 passes through, the inner space of the 1st cylindrical portion 24, the 2nd cylindrical portion 26 and the 3rd cylindrical portion 28, the imaginary cylindrical space connected therebetween and the imaginary cylindrical space from the 3rd cylindrical portion 28 to the bottom of the 1st conveying portion 14 and the top of the guide portion 30 become the passage 10 that the tubular article 100 moves. Therefore, the position just above the guide portion 30 becomes the outlet 5 of the passage 10. In the present embodiment, the direction of the axis A of the passage 10 is along the vertical direction. In addition, the guide portion 30 is provided with a curved surface 36, so that when the tubular article 100 processed by the cutting portion 12 comes out from the outlet 5, the tubular article 100 is guided in a direction different from the direction of the axis A of the passage 10.

[0046] Figure 5 1 is a perspective view showing a cutting unit 12 of a tubular article processing device 1 according to an embodiment of the present invention. Figure 5 As shown, the cutting unit 12 includes a rotating unit 38 formed in a hollow disk shape and rotatable about the axis A of the passage 10 , and a pair of cutting blades 40 disposed inside the rotating unit 38 .

[0047] The third cylindrical portion 28 is formed integrally with the rotating portion 38 at the center of the rotating portion 38. A pair of mounting bases 42 for mounting the cutting blade 40 are formed on the outer side of the third cylindrical portion 28. The mounting bases 42 are respectively provided on the opposite sides in the radial direction with respect to the axis A, and have inclined surfaces 44 so that when the cutting blade 40 is mounted on the mounting bases 42, it forms a predetermined angle with respect to the axis A. The rotating portion 38 is provided so as to be rotatable about the axis A by the operation of the operating portion 8 transmitted by the power transmission portion 18.

[0048] The cutting blade 40 is configured so that, when mounted on the mounting table 42, a part of the cutting blade 40 protrudes from the notch 46 formed in the third cylindrical portion 28 to the inside of the third cylindrical portion 28. In addition, in the present embodiment, the second cylindrical portion 26 and the third cylindrical portion 28 are arranged to be continuous, so if these second cylindrical portion 26 and the third cylindrical portion 28 are regarded as one cylindrical portion, it can also be considered that the cutting blade 40 is configured to protrude from the opening formed in one cylindrical portion to the inside of the cylindrical portion.

[0049] Figure 6 and Figure 7 1 is a diagram for explaining the installation position of the cutting blade 40 of the cylindrical article processing device 1 according to one embodiment of the present invention. Figure 6 and Figure 7 As shown, when the surface including the cutting blade 40 is arranged perpendicular to the direction of the axis A of the passage 10, and the extending direction X of the cutting blade 40 is arranged as the radial direction of the passage 10, the direction perpendicular to the direction X and the axis A is set as the direction Y. Figure 6As shown, from this state, the cutting blade 40 is rotated downward by an angle α with the direction X as the center. Figure 7 As shown, from this state, the cutter blade 40 is further rotated downward by an angle β around the direction Y. The cutter blade 40 is arranged at this angular position relative to the passage 10 .

[0050] Here, in this embodiment, the angle α is set larger than the angle β, preferably 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°.

[0051] As stated Figures 2 to 4 As shown, the first conveying unit 14 is disposed on the passage 10 between the cutting unit 12 and the guide unit 30 , and includes a pair of first rollers 48 disposed on both sides of the passage 10 .

[0052] Figure 8 1 is a perspective view showing the first roller 48 of the first conveying unit 14 of the tubular article processing apparatus 1 according to one embodiment of the present invention. Fig. 9 1 is a cross-sectional view showing the first roller 48 of the first conveying section 14 of the tubular article processing device 1 according to one embodiment of the present invention. The first roller 48 includes a rotating shaft 50, a pair of flanges 52 provided on the rotating shaft 50 at a predetermined interval, and a main body 54 formed between the pair of flanges 52, wherein the diameter of the main body 54 is smaller than the diameter of the flanges 52 and larger than the diameter of the rotating shaft 50. A plurality of first protrusions 56 are formed on the main body 54, and the plurality of first protrusions 56 extend from one flange 52 to the other flange 52 through the main body 54. The first protrusions 56 protrude from the main body 54 and the flanges 52 in the radial direction or at a predetermined angle relative to the radial direction, and extend parallel to the rotating shaft 50 at equal intervals around the rotating shaft 50. The first protrusions 56 have a substantially rectangular or trapezoidal cross section, and have a flat top.

[0053] Interlocking gears 58 are integrally formed on the rotation shafts 50 of the first rollers 48 , respectively. 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 one first roller 48 .

[0054] As stated Figures 2 to 4 As shown, the second transport unit 16 is disposed on the passage 10 between the cutting unit 12 and the first cylindrical unit 24 , and includes a pair of second rollers 60 disposed on both sides of the passage 10 .

[0055] Fig.10 1 is a perspective view showing the second roller 60 of the second conveying section 16 of the tubular article processing apparatus 1 according to one embodiment of the present invention. Fig.112 is a cross-sectional view of the second roller 60 of the second conveying section 16 of the tubular article processing device 1 according to one embodiment of the present invention. The second roller 60 includes a rotating shaft 62, a pair of flanges 64 provided on the rotating shaft 62 at a predetermined interval, and a main body 66 formed between the pair of flanges 64, wherein the diameter of the main body 66 is smaller than the diameter of the flanges 64 and larger than the diameter of the rotating shaft 62. A plurality of second protrusions 68 protruding in the radial direction from the main body 66 are formed on the main body 66. The second protrusions 68 protrude only from the main body 66 and do not extend to the flanges 64 in the direction of the rotating shaft 62. The second protrusions 68 are equally spaced around the rotating shaft 62 and extend parallel to the rotating shaft 62. The cross section of the second protrusion 68 is substantially triangular, and the tip thereof is sharp.

[0056] Interlocking gears 70 are integrally formed on the rotation shafts 62 of the second rollers 60 , respectively. When one second roller 60 rotates, the other second roller 60 rotates in the opposite direction to the one second roller 60 due to the mutual meshing of the interlocking gears 70 .

[0057] Fig.12 1 is a longitudinal sectional view of a cylindrical article processing device 1 according to an embodiment of the present invention. Fig.12 and stated Figures 8 to 11 , the distance D1 between the rotation axes 50 of the first roller 48 and the distance D2 between the rotation axes 62 of the second roller 60 are set to be the same. In addition, the length L1 of the first protrusion 56 of the first roller 48 in the direction of the rotation axis 50 is set to be larger than the length L2 of the second protrusion 68 of the second roller 60 in the direction of the rotation axis 62. The widths W11 and W12 of the top end portion of the first protrusion 56 of the first roller 48 are set to be larger than the width W2 of the top end portion of the second protrusion 68 of the second roller 60. The number of the first protrusions 56 of the first roller 48 is larger than the number of the second protrusions 68 of the second roller 60. The protrusion amount P1 of the first protrusion 56 from the main body 54 is set to be larger than the protrusion amount P2 of the second protrusion 68 from the main body 66. In addition, in Fig. 9 In the figure, the protrusion amount P1 is the protrusion amount of the first protrusion 56 with a substantially rectangular cross section, but the protrusion amount P1 is the same for the first protrusion 56 with a substantially trapezoidal cross section. In addition, the distance G1 between the top ends of the first protrusions 56 of the pair of first rollers 48 is set to be smaller than the distance G2 between the top ends of the second protrusions 68 of the pair of second rollers 60.

[0058] As stated Figures 2 to 4 As shown, 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 conveying unit 14, and a third transmission unit 76 that transmits the rotational power from the operating unit 8 to the second conveying unit 16 via the first transmission unit 72.

[0059] The first transmission part 72 includes a first bevel gear 80 fixed to the rotating shaft 78 of the operating part 8, a second bevel gear 82 meshing with the first bevel gear 80 and arranged above the rotating part 38 of the cutting part 12, an internal tooth 84 formed on the inner surface of the second bevel gear 82, a plurality of (three in this embodiment) planetary gears 86 meshing with the internal tooth 84, and a first gear 88 meshing with the plurality of planetary gears 86 and fixed to the second cylindrical part 26. In this embodiment, the passage 10 of the tubular article processing device 1 is arranged in the vertical direction in a normal use state, so the rotation axis of the rotating part 38 of the cutting part 12 is also in the vertical direction, and the rotation axis of the second bevel gear 82 is also consistent with the axis A of the passage 10. Since the rotating shaft 78 of the operating part 8 extends in the horizontal direction, the rotation axis of the first bevel gear 80 extends in a direction orthogonal to the axis A of the passage 10.

[0060] The second transmission portion 74 includes a second gear 89 fixed to the rotation shaft 78 of the operation portion 8 at a distal end side of the first bevel gear 80 , and a third gear 90 meshing with the second gear 89 and fixed to the rotation shaft 50 of one of the pair of first rollers 48 .

[0061] The third transmission portion 76 includes a third bevel gear 92 fixed on the second cylindrical portion 26 at a position above the first gear 88, a fourth bevel gear 96 meshing with the third bevel gear 92 and configured such 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 meshing with the fourth gear 98 and fixed to the rotation axis 62 of one of the pair of second rollers 60.

[0062] The gears of the power transmission unit 18 excluding the second bevel gear 82 and the planetary gear 86 have their rotation shafts rotatably supported by a support unit (not shown).

[0063] The rotating shaft 78 of the operating portion 8 includes 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 located closer to the operating portion 8 than the first rotating shaft 78A and to which the operating portion 8 is fixed. 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 and 75B are provided at the end of the first rotating shaft 78A on the side of the second rotating shaft 78B and the end of the second rotating shaft 78B on the side of the first rotating shaft 78A, respectively. The pair of cylindrical portions 75A and 75B are formed with teeth in the axial direction, and these teeth mesh with each other. The cylindrical portion 75A on the side of the first rotating shaft 78A is fixed to the first rotating shaft 78A. On the other hand, the cylindrical portion 75B of the second rotating shaft 78B is provided so as to be able to slide in the axial direction relative to the second rotating shaft 78B, but not to rotate relative to the second rotating shaft 78B. A spring 79 is provided between the cylindrical portion 75B and the operation portion 8 to bias the cylindrical portion 75B toward the cylindrical portion 75A.

[0064] The tube-shaped article processing device 1 of the present embodiment configured as described above operates as follows.

[0065] Fig.13 1 is a diagram for explaining the operation of the cylindrical article processing device 1 according to one embodiment of the present invention. The cylindrical article 100 is inserted into the first cylindrical portion 24 from the inlet 4. Furthermore, when the operating portion 8 is rotated by hand, the rotational power is transmitted to the first bevel gear 80 via the cylindrical portion 75B and the cylindrical portion 75A, and the rotational power is converted into the rotational power in the orthogonal direction by the second bevel gear 82, and then transmitted to the first gear 88 via the internal teeth 84 and the planetary gear 86. Since the first gear 88 is fixed to the second cylindrical portion 26, the second cylindrical portion 26 is rotated. At this time, the rotation direction of the second cylindrical portion 26 is opposite to the rotation direction of the second bevel gear 82.

[0066] When the third bevel gear 92 rotates due to the rotation of the second cylindrical portion 26, the rotation is converted into a rotational power in an orthogonal direction by the fourth bevel gear 96, so that the fourth gear 98 coaxially fixed with the fourth bevel gear 96 rotates. The fourth gear 98 meshes with the fifth gear 99 fixed to the rotating shaft 62 of one second roller 60, so that the fifth gear 99 rotates. Thus, one second roller 60 rotates, and here, since one second roller 60 meshes with another second roller 60 using the interlocking gear 70, when one second roller 60 rotates, the other second roller 60 rotates in the opposite direction. When a pair of second rollers 60 rotate, the second protrusion 68 clamps the tubular article 100 inserted between the second protrusions 68 and moves the tubular article 100 downward. In this way, the tubular article 100 is transported to the cutting portion 12 by the second roller 60.

[0067] The cylindrical article 100 that has passed between the second rollers 60 is inserted into the rotating second cylindrical portion 26, and is further inserted into the third cylindrical portion 28 in the rotating portion 38 of the cutting portion 12. Here, since the second cylindrical portion 26 is fixed to the rotating portion 38, the rotating portion 38 also rotates with the rotation of the second cylindrical portion 26. Since two cutting knives 40 protrude from the outer periphery of the third cylindrical portion 28, the cutting knives 40 cut the cylindrical article 100 while rotating as the cylindrical article 100 is conveyed downward by the second rollers 60. With this action, the cylindrical article 100 is cut into a spiral or coil shape.

[0068] The cut cylindrical article 100 comes out from the third cylindrical portion 28. Here, the rotational power from the operating portion 8 is transmitted to the second gear 89. Since the second gear 89 is meshed with the third gear 90 fixed to the rotating shaft 50 of one first roller 48, when one first roller 48 rotates, the other first roller 48 rotates in the opposite direction. When the pair of first rollers 48 rotates, the first protrusion 56 clamps the cylindrical article 100 passing therebetween and moves the cylindrical article 100 downward. The cylindrical article 100 cut into a coil shape is transported to the outlet 5 by the first roller 48.

[0069] The first roller 48 not only has the function of conveying the tubular article 100 cut into a coil shape toward the outlet 5 , but also has the function of pulling the tubular article 100 toward the cutting section 12 from the opposite side of the second roller 60 .

[0070] The cylindrical article 100 cut into a coil shape enters the guide portion 30. Since the guide portion 30 has a curved surface 36, the cylindrical article 100 changes its direction along the curved surface 36 from the vertical direction of the axis A of the passage 10 to the horizontal direction orthogonal to the vertical direction.

[0071] The cylindrical object 100 with the changed orientation comes out from the take-out port 6 of the housing 2. The user takes out the cylindrical object 100 that comes out from the take-out port 6. In this embodiment, the cylindrical object 100 taken out from the housing 2 is completely cut into a coil shape and cut (separated), so the user unwinds the cylindrical object 100 to make two coil-shaped objects.

[0072] For example, when a large load is applied to the power transmission unit 18 due to some unfavorable conditions such as the tubular article 100 being blocked midway, even if the operating unit 8 is rotated, the cylindrical portion 75B is difficult to rotate, and the rotational force of the cylindrical portion 75B overcomes the force of the spring 79, and the cylindrical portion 75B slides toward the operating unit 8, thereby not meshing with the cylindrical portion 75A, and the rotation of the operating unit 8 is not transmitted to the power transmission unit 18. By utilizing the structure composed of such cylindrical portions 75A, 75B and spring 79 to prevent the rotational power from the operating unit 8 from being transmitted, it is possible to prevent the internal mechanisms of the power transmission mechanism 18 and the like from being damaged due to the operation of the operating unit 8.

[0073] According to the present embodiment configured in this manner, the following excellent effects can be obtained.

[0074] Since the tubular article processing device 1 includes the passage 10, the cutting unit 12, and the first conveying unit 14, the cutting unit 12 can cut the tubular article 100 moving in the passage 10 into a coil. Thus, a coil-shaped article can be made from the cut tubular article 100. The user can select the tubular article 100 of the color, pattern, and length that he likes and easily make the coil-shaped article by himself.

[0075] In addition, since the first conveying unit 14 can convey the tubular article 100 toward the outlet 5, the tubular article 100 will not be blocked in the passage 10 and can be discharged well from the removal port 6. The first conveying unit 14 conveys the cut tubular article 100 toward the outlet 5, and also plays the role of pulling the uncut tubular article 100 from the outlet 5 and conveying it toward the cutting unit 12, so that the tubular article 100 can be prevented from being blocked at the cutting unit 12.

[0076] Since the cutting unit 12 includes the cutting blade 40 and the rotating unit 38 for rotating the cutting blade 40, the cutting blade 40 cuts the cylindrical object moving in the passage while rotating around the cylindrical object 100, thereby being able to cut the cylindrical object 100 into a coil shape. Since the cylindrical object 100 is not rotated relative to the cutting blade 40 but the cutting blade 40 is rotated relative to the cylindrical object 100 by the rotating unit 38, there is no need to provide a mechanism for moving the cylindrical object 100 in a coil shape in the passage 10 to complicate the mechanism, and the cylindrical object 100 can be cut into a coil shape with a simple structure.

[0077] The cylindrical article processing device 1 has an operating unit 8, and the rotating unit 38 is rotated by the user operating the operating unit 8, so that the cylindrical article 100 can be cut into a coil shape by simple operation. In addition, since the user cuts the cylindrical article 100 by actual operation, the user can obtain a sense of processing the cylindrical article 100, and the user can enjoy the pleasure of processing the cylindrical article 100.

[0078] Since the second conveying unit 16 is provided, the tubular article 100 can be conveyed to the cutting unit 12 by the second conveying unit 16. This prevents the tubular article 100 from not entering the cutting unit 12 and failing to be smoothly cut, and the tubular article 100 can be reliably cut.

[0079] The power transmission unit 18 transmits the power from the operating unit 8 to the rotating unit 38, the first conveying unit 14, and the second conveying unit 16. Therefore, by operating the single operating unit 8, the rotating unit 38, the first conveying unit 14, and the second conveying unit 16 can be simultaneously and easily operated. In the present embodiment, the power transmission unit 18 transmits the power using gears, so that the operations of the rotating unit 38, the first conveying unit 14, and the second conveying unit 16 can be operated in conjunction with each other, and the desired operation of the cooperation of each mechanism can be reliably performed.

[0080] The first conveying section 14 has the first roller 48, and the second conveying section 16 has the second roller 60, so that the tubular article 100 can be conveyed to the downstream side on both the upstream side and the downstream side of the cutting section 12, thereby preventing the tubular article 100 from being blocked in the passage 10 and other unfavorable situations, and the tubular article 100 can be reliably conveyed to the downstream side.

[0081] The first protrusion 56 is formed on the first roller 48, and the second protrusion 68 is formed on the second roller 60, and the configuration conditions of the first protrusion 56 and the second protrusion 68 are different. Specifically, the distance G1 between the first protrusions 56 provided on the pair of first rollers 48 is set to be smaller than the distance G2 between the second protrusions 68 provided on the pair of second rollers 60. Here, the first roller 48 conveys the tubular article 100 after being cut into a coil shape to the outlet 5, while the second roller 60 conveys the tubular article 100 before being cut into a coil shape to the cutting part 12, so that the tubular article 100 clamped by the first roller 48 is more easily bent (deformed) than the tubular article 100 clamped by the second roller 60. In the present 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 first protrusions 56 of the first roller 48 with a smaller distance G1 can be used to reliably clamp the easily flexible cylindrical article 100 cut into a coil shape, and the second protrusions 68 of the second roller 60 with a larger distance G2 can be used to reliably clamp the cylindrical article 100 that has not been cut without excessively flattening. Thus, the cylindrical article 100 can be moved well and reliably both before and after being cut into a coil shape.

[0082] The cutter 40 is arranged at the following position: the cutter 40 is rotated toward the outlet 5 by an angle α with the extension direction X of the cutter 40 as the axis, and the cutter 40 is rotated toward the outlet 5 by an angle β with the direction Y passing through the top of the cutter 40 and perpendicular to the axial direction A of the passage 10 and perpendicular to the extension direction of the cutter 40 as the axis, and at this time, the angle α is set to be greater than the angle β. Thus, the cutter 40 can be arranged at an appropriate angle relative to the axial direction A of the passage 10, and the tubular article 100 moving in the passage 10 will not block the passage 10 without being cut by the cutter 40, or the tubular article 100 will not be twisted, and the tubular article 100 can be well cut into a coil shape.

[0083] When the tubular article processing device 1 is arranged in a stable use position, the passage 10 is arranged in the vertical direction, the inlet 4 is located at the upper side in the vertical direction relative to the cutting portion 12, and the outlet 5 is located at the lower side in the vertical direction relative to the cutting portion 12. As a result, the tubular article 100 is easy to move in the passage 10, and the tubular article 100 can be prevented from being blocked in the passage 10, and the tubular article 100 can be reliably cut into a coil shape.

[0084] Since the guide portion 30 is provided on the downstream side of the passage 10, the cut cylindrical article 100 can be moved in a direction different from the axial direction A of the passage 10 by the guide portion 30. Thus, when the cylindrical article 100 is cut by the cutting portion 12, the passage 10 can be arranged in the vertical direction, and when the cut cylindrical article 100 is taken out, it is taken out from the take-out port 6 provided on the side surface of the cover portion 22 of the housing 2, so that the user can easily take out the cylindrical article 100.

[0085] In addition, the cut tubular article 100 is guided in a horizontal direction different from the axial direction A of the passage 10 by the guide portion 30. Therefore, there is no need to ensure a space for moving the tubular article 100 coming out of the outlet 5 of the passage 10 in the axial direction A of the passage 10. As a result, the dimension of the tubular article processing device 1 from the top of the cover portion 22 to the loading portion 20 can be reduced, which can contribute to the miniaturization of the tubular article processing device 1.

[0086] The second protrusion 68 plays the role of clamping the tubular article 100 that has not been cut into a spiral shape and conveying it toward the cutting part 12. At this time, the tubular article 100 has not been cut by the cutting part 12, so it is difficult to deform. In addition, when the cutting part 12 is used to cut the tubular article 100, if the resistance of the second roller 60 is large, the tubular article 100 cannot be cut well. Therefore, in this embodiment, the protrusion amount P2 of the second protrusion 68 is set to be smaller than the protrusion amount P1 of the first protrusion 56 on the outlet 5 side and the distance G2 between the top ends of the second protrusion 68 is set to be larger than the distance G1 between the top ends of the first protrusion 56 on the outlet 5 side, therefore, the tubular article 100 is clamped by the second protrusion 68, and when the resistance at the cutting part 12 is large, the tubular article 100 slides at the second protrusion 68 when necessary, thereby, the tubular article 100 can be easily conveyed and the tubular article 100 can be easily cut by the cutting part 12.

[0087] The first protrusion 56 plays a role in forcibly discharging the tubular article 100 toward the outlet 5. At this time, the tubular article 100 is cut into a spiral shape by the cutting knife 40 and is easily deformed. Therefore, by setting the protrusion amount P1 of the first protrusion 56 to be larger than the protrusion amount P2 of the second protrusion 68 on the inlet 4 side and making the distance G1 between the top ends of the first protrusion 56 smaller than the distance G2 between the top ends of the second protrusion 68, the tubular article 100 can be reliably grasped and easily transported to the outlet 5 side.

[0088] The widths W11 and W12 of the top end of the first protrusion 56 are set to be larger than the width W2 of the top end of the second protrusion 68. As a result, the area of ​​the top end of the first protrusion 56 is larger than the area of ​​the top end of the second protrusion 68, and the contact area between the first protrusion 56 and the tubular article 100 becomes larger. As a result, the friction between the first protrusion 56 and the tubular article 100 can be made larger than the friction between the second protrusion 68 and the tubular article 100, and the tubular article 100 can be more reliably sent to the outlet 5 side by the first protrusion 56. In addition, the fact that the length L1 of the top end of the first protrusion 56 is larger than the length L2 of the top end of the second protrusion 68 also helps to increase the contact area between the first protrusion 56 and the tubular article 100.

[0089] The second transmission part 74 has a second gear 89 fixed to the rotation shaft 78 of the operating part 8 and a third gear 90 fixed to the rotation shaft 50 of one first roller 48, so that the rotation of the operating part 8 is directly transmitted to the first roller 48. Here, the first roller 48 has a function of discharging the cylindrical article 100 cut into a spiral shape to the outlet 5 side, but after the cylindrical article 100 is cut into a spiral shape and the uppermost end is separated from the second roller 60, the cylindrical article 100 that has not been cut is pulled toward the cutting part 12 by only the first roller 48, and the cylindrical article 100 that has been cut is conveyed to the outlet 5 side. In this embodiment, the transmission mechanism of the second transmission part 74 is composed of a small number of components, and is configured so that the rotation of the operating part 8 is directly transmitted to the first roller 48, so that the rotational force from the operating part 8 can be well transmitted to the first roller 48, and the rotational force required by the first roller 48 can be obtained with a smaller force.

[0091] In the embodiment described, the tubular article 100 is cut into a coil shape by the cutting knife 40 and is completely separated, but it is not limited to this. For example, the cutting knife 40 can also be used to form a slit in the thickness of the tubular article 100, so as to cut the tubular article 100 into a state where part or all of the tubular article 100 is not separated. Such a cutting method is also included in "cutting into a coil shape" in the present invention. When the tubular article 100 is not completely separated, it can be cut into a coil-shaped article by hand along the slit by the user, or a device of a subsequent process can be set to automatically cut it. In short, the cutting portion only needs to cut the tubular article into a separable coil shape.
