DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Preferred embodiments of the present invention will now be described.

[0010] 1 shows a tape winding device 100, a hose (wrapped object) 110, and a hose holding device 120. The hose 110 is held substantially horizontally by the hose holding device 120. The tape winding device 100 winds tape around the hose 110.

[0011] The hose holding device 120 has a plurality of first hose holding devices 121 and a plurality of second hose holding devices 122. Both longitudinal ends of the hose 110 are held by the first hose holding devices 121. The portion of the hose 110 other than the both longitudinal ends is held by the plurality of second hose holding devices 122 at intervals.

[0012] The tape winding device 100 includes two tape winding mechanisms (a first tape winding mechanism 1 and a second tape winding mechanism 2), three holders (a first holder 3, a second holder 4 and a third holder 5), a connecting member 6 and a control member 7. The three holders (the first holder 3, the second holder 4 and the third holder 5) each hold the hose 110 by pinching it from both sides in the radial direction. The three holders (the first holder 3, the second holder 4 and the third holder 5) temporarily hold both sides of the tape winding position when the tape is wound around the hose 110.

[0013] The two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and the three holders (first holder 3, second holder 4, third holder 5) are disposed on a connecting member 6. The connecting member 6 connects the two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and the three holders (first holder 3, second holder 4, third holder 5).

[0014] The first tape winding mechanism 1 and the second tape winding mechanism 2 are aligned in the longitudinal direction of the hose 110. A first holder 3 and a third holder 5 are disposed on either side of the first tape winding mechanism 1 and the second tape winding mechanism 2. A second holder 4 is disposed between the first tape winding mechanism 1 and the second tape winding mechanism 2.

[0015] The connecting member 6 is disposed on a rail 130. The rail 130 is long in the longitudinal direction of the hose 110. The connecting member 6 is movable on the rail 130 in the longitudinal direction of the hose 110 by a driving member such as a motor (not shown).

[0016] The movement of the connecting member 6 is controlled by a control member 7. The control member 7 can control the movement direction, movement speed, timing of starting and stopping movement, movement distance, etc. of the connecting member 6. As the connecting member 6 moves, the two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and three holders (first holder 3, second holder 4, third holder 5) move together.

[0017] The first tape winding mechanism 1 and the second tape winding mechanism 2, for example, wind tapes of different colors around the hose 110. The first tape winding mechanism 1 and the second tape winding mechanism 2 have the same configuration. Below, the first tape winding mechanism 1 will be described, and a description of the second tape winding mechanism 2 will be omitted.

[0018] FIG. 2 shows the first tape winding mechanism 1 as viewed from the direction II in FIG. 1, along with the control member 7 and the like.

[0019] As shown in FIG. 2, the first tape winding mechanism 1 has a rotating member 11, a tape holding member 12, a guide member 13, a protrusion 14, a blade member 15, a moving member 16, and a movable member 17.

[0020] Rotating member 11 is annular with a portion open. A space in which hose 110 (see FIG. 1) can be disposed is formed inside rotating member 11. The inside of rotating member 11 communicates with the outside of rotating member 11 via opening 11A.

[0021] The rotating member 11 is rotated around a rotating shaft 11C by a driving member (not shown) such as a motor. The rotation of the rotating member 11 is controlled by a control member 7. The control member 7 can control the rotation speed, the number of rotations, the timing of starting and ending the rotation, and the like.

[0022] The rotation speed of the rotating member 11 is preferably 200 rpm or less, and more preferably 175 rpm or less. By setting the rotation speed of the rotating member 11 to 200 rpm or less, the tension of the tape 151 is stable and the tape winding state is good. Here, "good tape winding state" means that the wound tape 151 is hardly shifted in the winding direction of the tape 151. There is no particular lower limit to the rotation speed of the rotating member 11, but in consideration of the efficiency of the tape winding operation, the rotation speed of the rotating member 11 is preferably 75 rpm or more, and more preferably 100 rpm or more.

[0023] The tape holding member 12, the guide member 13, the protrusion 14, and the blade member 15 are held by the rotating member 11. As the rotating member 11 rotates, the tape holding member 12, the guide member 13, the protrusion 14, and the blade member 15 rotate around the rotation axis 11C.

[0024] The tape holding member 12 holds a tape roll 150 around which a tape is wound. The tape roll 150 is often cylindrical. The tape holding member 12 has a shape that can hold the cylindrical tape roll 150 from the inside, for example. The tape holding member 12 has a cylindrical or cylindrical shape, for example, as shown in FIG. 2.

[0025] The guide member 13, the protrusion 14 and the blade member 15 are disposed on the opposite side of the rotation shaft 11C to the opening 11A. The protrusion 14 is disposed between the guide member 13 and the blade member 15. The guide member 13, the protrusion 14 and the blade member 15 are closer to the tape holding member 12 in this order.

[0026] Guide member 13, protrusion 14, and blade member 15 protrude toward the inside of rotating member 11. A portion of guide member 13, a portion of protrusion 14, and a portion of blade member 15 are disposed on the inside of rotating member 11 relative to the circumferential inner surface of rotating member 11. Guide member 13, protrusion 14, and blade member 15 protrude toward opening 11A.

[0027] In the circumferential direction of the rotating member 11, the tape holding member 12 is disposed between the opening 11A and the protrusion 14. Fig. 2 shows a line L connecting the center 12C of the cylindrical tape holding member 12 and the rotation axis 11C of the rotating member 11. The angle between the line L and the protruding direction s of the guide member 13 is preferably an acute angle or 90°. The angle between the line L and the protruding direction s of the protrusion 14 is preferably an acute angle or 90°. The angle between the line L and the protruding direction s of the blade member 15 is preferably an acute angle or 90°.

[0028] In this embodiment, the angle formed by the line L and the protruding direction s of the guide member 13 is an acute angle. The angle formed by the line L and the protruding direction s of the protrusion 14 is an acute angle. The angle formed by the line L and the protruding direction s of the guide member 13 is an acute angle.

[0029] Guide member 13 is a member that guides tape 151 when tape 151 is attached to hose 110 by protrusion 14. By guiding tape 151 with guide member 13 when tape 151 is attached to hose 110 by protrusion 14, it is possible to suppress the occurrence of positional deviation, twisting, wrinkles, etc. of tape 151 on hose 110.

[0030] The tip 14T of the protrusion 14 is recessed toward the opposite side to the rotation shaft 11C and is curved. The tip 14T of the protrusion 14 has a shape that fits along the curved surface of the hose 110.

[0031] 2, a tip 15t of the blade member 15 protrudes toward the inside of the rotating member 11. Also, a tape pressing portion 15T is provided at the tip of the blade member 15. The thickness of the tape pressing portion 15T increases on the side opposite to the tape holding member 12 with increasing distance from the tip 15t.

[0032] A space capable of accommodating the rotating member 11 is formed inside the moving member 16. The inner surface of the moving member 16 is circumferential. The rotating member 11 is disposed inside the moving member 16. The moving member 16 holds the rotating member 11 rotatably.

[0033] An opening 16A is formed in the moving member 16. The opening 16A allows communication between the inside and outside of the moving member 16. When the rotation of the rotating member 11 stops at the position shown in Fig. 2, the opening 11A of the rotating member 11 and the opening 16A of the moving member 16 are in communication. At this time, the inside of the rotating member 11 and the outside of the moving member 16 are in communication via the opening 11A and the opening 16A.

[0034] The moving member 16 can be moved in the Y direction and the Z direction in FIG. 2 by a driving member (not shown) such as a damper or a cylinder. Here, the Y direction and the Z direction are directions perpendicular to the axial direction (X direction) of the rotating shaft 11C. The X direction is also the longitudinal direction of the hose 110 when the hose 110 is arranged as shown in FIG. 1. The Z direction is the vertical direction and also the up-down direction. The Y direction is a direction perpendicular to the X direction and the Z direction. The moving member 16 may be movable in the radial direction of the rotating member 11 other than the X direction, the Y direction, and the Z direction. When the rotation of the rotating member 11 stops at the position shown in FIG. 2, the opening 11A of the rotating member 11 and the opening 16A of the moving member 16 communicate with each other in the Y direction.

[0035] The movement of the moving member 16 is controlled by the control member 7. The control member 7 can control the moving direction, moving distance, moving speed, and timing of starting and stopping the movement of the moving member 16.

[0036] As the moving member 16 moves, the rotating member 11 held by the moving member 16, the tape holding member 12, the guide member 13, the protrusion 14 and the blade member 15 held by the rotating member 11, and the movable member 17 described later move together with the moving member 16.

[0037] The movable member 17 is disposed on the outer side of the rotating member 11. In this embodiment, the movable member 17 is disposed on the outer side of the moving member 16. The movable member 17 is attached to the moving member 16.

[0038] The movable member 17 has a first movable portion 17p and a second movable portion 17q. The first movable portion 17p and the second movable portion 17q are disposed on the outer side of the movable member 16, sandwiching a region overlapping with the opening 16A in the Y direction.

[0039] The first movable part 17p and the second movable part 17q can be protruded in a direction toward each other by a driving member (not shown) such as a damper or a cylinder, and the first movable part 17p and the second movable part 17q can be retracted in a direction away from each other.

[0040] The movements of the first movable part 17p and the second movable part 17q are controlled by a control member 7. The control member 7 can control the direction, distance, timing, and speed of movement of the first movable part 17p and the second movable part 17q.

[0041] Next, an example of a process for winding tape using the tape winding device 100 will be described with reference to Figures 1 and 3 to 9. Here, an example of partially winding tape around a plurality of locations on the hose 110 will be described.

[0042] As shown in FIG. 1, a hose holding device 120 holds a hose 110 horizontally.

[0043] The tape winding device 100 is capable of winding tapes of two colors around the hose 110. The first tape winding mechanism 1 and the second tape winding mechanism 2 each hold a tape roll of a different color.

[0044] The tape winding device 100 moves in the longitudinal direction of the hose 110 and stops at the tape winding position. When the tape winding device 100 passes through the portion held by the second hose holder 122, the hold of the hose 110 by the second hose holder 122 is released. Also, when the tape winding device 100 is at the stopped position, the hold of the hose 110 by the second hose holder 122 is released.

[0045] When the tape winding device 100 stops at the tape winding position, the holders on both sides of the tape winding mechanism that winds the tape hold the hose. For example, when the first tape winding mechanism 1 winds the tape, the first holder 3 and the second holder 4 on both sides of the first tape winding mechanism 1 hold the hose 110. When the second tape winding mechanism 2 winds the tape, the second holder 4 and the third holder 5 on both sides of the second tape winding mechanism 2 hold the hose 110. When the winding of the tape or the like is completed, the holders release the hold of the hose 110.

[0046] Fig. 3(a) shows the first tape winding mechanism 1 as viewed from the direction II in Fig. 1. When the tape winding device 100 shown in Fig. 1 moves in the longitudinal direction of the hose 110, the hose 110 is disposed between the first movable part 17p and the second movable part 17q on the outer side of the rotating member 11 and the moving member 16, as shown in Fig. 3(a). At this time, the opening 11A and the opening 16A communicate with each other in the Y direction, and the hose 110, the opening 16A, the opening 11A, and the protrusion 14 are aligned in a straight line in the Y direction.

[0047] The same applies to the second tape winding mechanism 2 shown in FIG.

[0048] The following describes in order the process of winding the tape by the first tape winding mechanism 1. The process of winding the tape by the second tape winding mechanism 2 is similar to the process of winding the tape by the first tape winding mechanism 1, so a description thereof will be omitted.

[0049] 3(a), a tape winding body 150 is held by the tape holding member 12. A tape 151 is pulled out from the tape winding body 150. The tape 151 is pulled out to a position where it overlaps with the tip of the guide member 13 and the tip of the protrusion 14 in the Y direction. The application surface of the tape 151 (the surface with adhesive or the like) is the surface opposite the protrusion 14.

[0050] [Painting the tape] From the state shown in Fig. 3(a), the moving member 16 moves in the Y direction so that the protrusion 14 approaches the hose 110. The hose 110 passes through the opening 16A and the opening 11A, and is disposed inside the rotating member 11 (see Fig. 3(b)). The moving member 16 moves in the Y direction so that the protrusion 14 approaches even closer to the hose 110 (see Fig. 4(a)).

[0051] The protrusion 14 presses the hose 110 from above the tape 151 (see FIG. 4(a)), whereby the end of the tape 151 sticks to the hose 110. When the protrusion 14 presses the hose 110, the moving member 16 stops, and the protrusion 14 moves in the Y direction away from the hose 110, and then stops (see FIG. 4(b)). The moving member 16 stops at a position where the rotation axis 11C of the rotating member 11 approximately coincides with the central axis of the hose 110.

[0052] [Tape wrapping] Next, the rotating member 11 rotates (see FIG. 5(a)). As the rotating member 11 rotates, the tape winding body 150, the guide member 13, the protrusion 14 and the blade member 15 rotate around the hose 110. As the tape winding body 150 rotates, the tape 151 is wound around the hose 110 (see FIG. 5(b)). When the required amount of tape has been wound, the rotating member 11 stops (see FIG. 6(a)).

[0053] [Cutting the tape and attaching the tape ends] After the tape 151 is wound, if the tip 15t of the blade member 15 and the tape 151 (the tape 151 between the tape roll 150 and the hose 110) do not overlap in the Y direction as shown in Figure 6(a), the moving member 16 moves as follows.

[0054] The moving member 16 moves in the Z direction (here, the upward direction in the figure) so that the blade member 15 approaches the tape 151. As shown in Fig. 6(b), the moving member 16 stops at a position where the tip 15t of the blade member 15 and the tape 151 (the tape 151 between the tape roll 150 and the hose 110) overlap in the Y direction. It is preferable that the stopping position of the movable member 16 is the position described above, and also a position where the tip 15t of the blade member 15 is located on a tangent to the hose 110 in the Y direction or on a tangent to the tape wrapped around the hose 110, or in the vicinity of these.

[0055] After the moving member 16 stops, the moving member 16 moves in the Y direction (to the right in the figure) so that the tip 15t of the blade member 15 approaches the hose 110 (see FIG. 7(a)). The tip 15t of the blade member 15 comes into contact with the tape 151. This causes the tape 151 to be cut. Even after the tape 151 is cut, the moving member 16 moves slightly in the same direction (to the right in the figure) (see FIG. 7(b)). This causes the tape pressing portion 15T of the blade member 15 to push the end of the tape wrapped around the hose 110 towards the hose 110. As a result, the end of the tape sticks to the hose 110 without becoming wrinkled.

[0056] [Movement of moving parts] 7(b), the moving member 16 moves in the Y and Z directions so that the hose 110 is disposed near the center inside the rotating member 11. In addition, the moving member 16 moves in the Y and Z directions so that the hose 110 is aligned in the Y direction with the opening 11A of the rotating member 11 and the opening 16A of the moving member 16.

[0057] Specifically, the moving member 16 moves in the Y direction (leftward in the figure) so that the blade member 15 moves away from the hose 110 (see FIG. 8(a)). Also, the moving member 16 moves in the Z direction (downward in the figure) so that the hose 110 is aligned with the openings 11A and 16A in the Y direction (see FIG. 8(b)). When the opening 11A and the opening 16A do not communicate with each other in the Y direction, the control member 7 rotates the rotating member 11 so that the opening 11A and the opening 16A communicate with each other in the Y direction.

[0058] 8(b), the moving member 16 moves in the Y direction (leftward in the figure) so that the rotating member 11 moves away from the hose 110. The hose 110 passes through the opening 11A and the opening 16A and is disposed outside the moving member 16 (see FIG. 9(a)). The hose 110 is disposed between the first moving part 17p and the second moving part 17q.

[0059] [Attaching the tape ends] First movable part 17p and second movable part 17q protrude towards hose 110 and sandwich hose 110 (see FIG. 9(b)). Here, an end of a tape is present on hose 110 in a position facing first movable part 17p (see FIG. 7(a) and FIG. 7(b)). First movable part 17p presses the end of the tape against hose 110. This ensures that the end of the tape is securely attached to hose 110 without any wrinkles. Then, first movable part 17p and second movable part 17q retract in a direction away from hose 110 (see FIG. 9(a)).

[0060] When the above steps, such as winding of the tape, are completed, the tape winding device 100 shown in FIG. 1 moves to another tape winding position and winds the tape at the other tape winding position.

[0061] According to this embodiment, the following effects can be obtained. As shown in Fig. 2, the rotating member 11 holds a tape winding body 150 and a blade member 15 that cuts the tape. In addition, the rotating member 11 also holds a guide member 13 and a protrusion 14. In this way, a plurality of members required for the tape winding operation are held by a single member (the rotating member 11). Therefore, it is possible to provide a tape winding device 100 with a small number of parts and a simple configuration.

[0062] In this embodiment, as shown in Fig. 2, the blade member 15 protrudes toward the inside of the rotating member 11. The blade member 15 is not present on the outside of the rotating member 11. This makes it possible to provide a compact tape winding device 100. Also, because the tape is cut inside the rotating member 11, the work area can be made smaller.

[0063] 2, the movable member 16 is movable in the Y and Z directions. This makes it possible to cut the tape at or near the end of tape winding, regardless of where the end of tape winding is located on the hose 110.

[0064] 2, a tape pressing portion 15T is formed at the tip of the blade member 15. After the tape 151 is cut, the tape end can be pressed against the hose 110 by the tape pressing portion 15T (see FIGS. 7(a) and 7(b)). Therefore, the end of the tape sticks to the hose 110 without wrinkling.

[0065] 2, movable member 17 (first movable part 17p, second movable part 17q) is disposed on the outside of rotating member 11. By pressing the tape end against hose 110 with movable member 17 (see Figs. 9(a) and 9(b)), the tape end adheres to hose 110 without wrinkling. Furthermore, if the tape end is pressed against hose 110 by tape pressing part 15T inside rotating member 11 before the tape end is pressed against hose 110 by movable member 17, the tape end is pressed against hose 110 twice, so that the tape end reliably adheres to hose 110 without wrinkling.

[0066] Also, as shown in Figures 3(b), 4(a) and 4(b), before the tape is wound, the end of the tape 151 pulled out from the tape roll 150 can be automatically attached to the hose 110 by the protrusion 14.

[0067] Furthermore, by controlling the rotation speed of the rotating member 11 to 200 rpm or less, the tape winding state is good after the winding of the tape 151 shown in Figs. 3 to 9 is completed.

[0068] 1, the first tape winding mechanism 1 is connected to the first holder 3 and second holder 4 on either side thereof. Therefore, they move together. As a result, regardless of the tape winding position, the first holder 3 and second holder 4 are disposed on either side of the first tape winding mechanism, and both sides of the tape winding position are held by the first holder 3 and the second holder 4. Therefore, the tape can be stably wound around the hose 110. The same applies to the second tape winding mechanism 2 and the second holder 4 and third holder 5 on either side thereof.

[0069] In addition, with the previous method, it was only possible to wrap tape of one color in one go. When wrapping tapes of multiple colors, the process of wrapping tape of one color from one end of the hose to the other, and then wrapping tape of the other color from one end of the hose to the other, had to be repeated. 1, the tape winding device 100 is equipped with multiple tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2), and each mechanism can wind a different color tape. The multiple tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) are connected by a connecting member 6. This makes it possible to wind tapes of multiple colors around the hose 110 in a single operation of moving the tape winding device 100 (excluding the control member 7) from one end of the hose 110 to the other end. EXAMPLES

[0070] The present invention will be described in more detail below with reference to examples. However, the following examples do not limit the present invention, and all modifications and variations within the scope of the present invention are included in the technical scope of the present invention.

[0071] 〔experiment〕 Tape was wrapped around a hose using a tape wrapping device with a configuration similar to that shown in Figures 1 and 2. The rotation speed of the rotating member (tape wrapping rotation speed) was changed to check the tape wrapping state, workability, and appearance of the rotating member during work.

[0072] [Tape wrapping state] The state of the tape wrapping was checked immediately after and one day after the steps similar to those shown in Figs. 3 to 9 (tape wrapping, etc.). (Right after wrapping tape, etc.) The case where the wound end of the tape was not displaced in the winding direction of the tape was marked as "Excellent". The case where the wound end of the tape was slightly misaligned in the winding direction of the tape was marked as "◯". A case where the wound end of the tape was slightly deviated from the winding direction of the tape was rated as "Δ". The symbol "◎" indicates that the tape is wrapped in a good condition. The symbols "◯" and "△" indicate that the end of the tape is slightly or slightly misaligned in the wrapping direction, but the symbols "◯" and "△" indicate that the tape is wrapped in a good condition, just like the symbol "◎". (One day after wrapping the tape, etc.) The case where the tape end was unchanged from immediately after the tape was wrapped was marked with "Excellent". The case where the tape end was almost the same as immediately after wrapping the tape, but the tape end was slightly lifted was marked as "good". The case where the tape end was almost the same as immediately after wrapping the tape, but the tape end was slightly lifted was rated as "Δ". The symbol "◎" indicates that the tape was wrapped in a good condition. The symbols "◯" and "△" indicate that the tape end was slightly or slightly raised, but the symbols "◯" and "△" indicate that the tape was wrapped in a good condition, just like the symbol "◎".

[0073] [Workability] The efficiency of the tape winding work was evaluated. A case in which the tape winding work was done quickly and efficiently was given a "Excellent" rating. The case where the tape winding work was slightly slower than "◎" but fast was marked as "○". A case where the tape winding work was slightly slower than "○" but relatively fast was marked "△".

[0074] [Status of rotating parts during operation] The state of the rotation speed of the rotating member during the tape winding operation was observed. When the operator felt that the rotation speed of the rotating member was good, the operator marked it with "Excellent." When the operator felt that the rotation speed of the rotating member was slightly faster than "A", the operator marked it as "O". When the operator felt that the rotation speed of the rotating member was slightly faster than "A", the operator marked it as "B". It should be noted that "◎", "◯" and "△" are all impressions received by the worker and indicate no problems with workability or the like.

[0075] [Table 1]

[0076] As can be seen from Table 1, when the tape winding rotation speed was 50 rpm or more and 250 rpm or less, the tape winding condition was good both immediately after tape winding, etc. and one day later. In particular, when the tape winding rotation speed was 50 rpm or more and 200 rpm or less, there was no slight misalignment or lifting of the tape ends both immediately after tape winding, etc. and one day later, and the tape winding condition was very good.

[0077] In addition, when the tape winding rotation speed was 50 rpm or more and 250 rpm or less, the workability was good both immediately after and one day after tape winding, etc. In particular, when the tape winding rotation speed was 100 rpm or more and 250 rpm or less, the work was faster than when the tape winding rotation speed was 50 rpm or more and 75 rpm.

[0078] In addition, when the tape winding rotation speed was 50 rpm or more and 250 rpm or less, there were no problems with the rotation speed of the rotating members during work. In particular, when the tape winding rotation speed was 50 rpm or more and 175 rpm or less, the worker felt that the rotation speed of the rotating members was very good.

[0079] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration should not be considered to be limited to these embodiments. The scope of the present invention is indicated by the claims, not by the above description, and includes all modifications within the meaning and scope of the claims.

[0080] For example, in this embodiment, as shown in the enlarged view of Fig. 2, a tape pressing portion 15T having a larger thickness is formed at the tip of the blade member 15. However, the tip of the blade member 15 does not necessarily have to have the tape pressing portion 15T formed thereat.

[0081] 2, the tip 14T of the protrusion 14 is recessed and curved toward the opposite side of the rotation shaft 11C. However, the shape of the tip 14T of the protrusion 14 is not limited to the above and can be changed. For example, the tip 14T of the protrusion 14 may be flat.

[0082] 2, the rotating member 11 and the protrusion 14 are separate members. However, the rotating member 11 and the protrusion 14 may be integrated together. For example, a part of the inner surface of the rotating member 11 may be the protrusion 14 that protrudes toward the inside of the rotating member 11.

[0083] 2 includes a guide member 13 and a protrusion 14. However, the tape winding device does not necessarily have to include the guide member 13 and the protrusion 14. The tape winding device does not necessarily have to include the protrusion 14.

[0084] In the configuration shown in FIG. 2, the guide member 13, the protrusion 14, and the blade member 15 are disposed on the opposite side of the opening 11A with respect to the center of the rotating member 11, and protrude toward the opening 11A. The guide member 13, the protrusion 14, and the blade member 15 are disposed at a position overlapping the opening 11A in the Y direction. The guide member 13, the protrusion 14, and the blade member 15 are disposed adjacent to each other, and are closer to the tape holding member 12 in this order. However, the positions, protrusion directions, and arrangements of the guide member 13, the protrusion 14, and the blade member 15 are not limited to the positions and protrusion directions shown in FIG. 2, and can be changed. For example, the guide member 13, the protrusion 14, and the blade member 15 may protrude toward a portion where the opening 11A is not formed. The guide member 13, the protrusion 14, and the blade member 15 may be disposed at a position not overlapping the opening 11A in the Y direction. The guide member 13, the protrusion 14, and the blade member 15 may be disposed apart.

[0085] 2, the angle formed by the line L and the protruding direction Y of the guide member 13 is an acute angle, but this angle may be 90°. The angle formed by the line L and the protruding direction Y of the protrusion 14 is an acute angle, but this angle may be 90°. The angle formed by the line L and the protruding direction Y of the guide member 13 is an acute angle, but this angle may be 90°.

[0086] 2, the movable member 17 has a first movable part 17p and a second movable part 17q that face each other. The first movable part 17p and the second movable part 17q protrude toward each other and sandwich the hose 110. However, the configuration of the movable member 17 is not limited to the above configuration and can be changed. For example, the movable member 17 may be configured to include only the first movable part 17p or the second movable part 17q. Also, the tape winding device may not be configured to include the movable member 17.

[0087] 9(a) and 9(b), first movable part 17p and second movable part 17q protrude toward hose 110. However, when an end of the tape is located on hose 110 at a position facing first movable part 17p, only first movable part 17p may protrude toward hose 110. When an end of the tape is located on hose 110 at a position facing second movable part 17q, only second movable part 17q may protrude toward hose 110.

[0088] 2, the movable member 17 is disposed outside the moving member 16. However, the movable member 17 may be disposed outside the rotating member 11 and inside the moving member 16. For example, the opening 16A of the moving member 16 may be large, and the movable member 17 may be disposed in the opening 16A.

[0089] In the above-described embodiment, the control member 7 shown in Fig. 1 controls the rotation of the rotating member 11, the movement of the moving member 16, the movement of the movable member 17, and the movement of the connecting member 6 shown in Fig. 1. However, the rotation, movement, and movement of each member may be controlled by a different control member. In this case, all the control members are collectively referred to as the control members.

[0090] 1 is not connected to the two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2). However, the control member 7 may be connected to the two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and move together with them in the longitudinal direction of the hose 110. For example, the control member 7 may be disposed on the connecting member 6.

[0091] 1, two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and three holders (first holder 3, second holder 4, third holder 5) are connected by being placed on a connecting member 6. However, the configuration for connecting multiple tape winding mechanisms, the configuration for connecting multiple holders, and the configuration for connecting the tape winding mechanisms and the holders are not limited to the above configuration and can be changed.

[0092] 1, the tape winding device 100 is equipped with holders (first holder 3, second holder 4, third holder 5) that temporarily hold the hose 110, and the holders (first holder 3, second holder 4, third holder 5) are arranged on both sides of the tape winding mechanism (first tape winding mechanism 1, second tape winding mechanism 2). However, the holders may be arranged on only one side of the tape winding mechanism. Also, the tape winding device does not have to be equipped with holders.

[0093] 1, the tape winding device 100 includes two tape winding mechanisms (first tape winding mechanism 1, second tape winding mechanism 2) and three holders (first holder 3, second holder 4, third holder 5) that temporarily hold the hose 110. However, the tape winding device may include only one tape winding mechanism, or may include three or more tape winding mechanisms. When the tape winding device 100 includes only one tape winding mechanism, it may not include the connecting member 6 shown in FIG. 1, and may be capable of controlling the movement of the moving member 16 (see FIG. 2) in the axial direction of the rotating shaft 11C of the rotating member (the longitudinal direction of the hose) by the control member 7.

[0094] Furthermore, when the tape winding device 100 includes multiple tape winding mechanisms, the multiple tape winding mechanisms may or may not be the same. [Explanation of symbols]
