[0009] <Embodiment> The wire winding device 3 according to this embodiment is a device that winds a wire 7 around a pair of drums 11 included in a capstan device 1 as shown in FIG. 1. The capstan device 1 rotates the pair of drums 11 with the wire 7 wound around them. The capstan device 1 includes the pair of drums 11, a pair of support parts 12 that support the drums 11, and a pair of motors 13. The wire 7 that can be wound around the pair of drums 11 according to this embodiment is not particularly limited, and examples thereof include electric wires, optical cables, wires, rubber hoses, and tubes. In this embodiment, an electric wire will be described as an example of the wire 7.

[0010] The pair of drums 11 are rotatably supported by a pair of support portions 12. Each drum 11 is formed in a cylindrical shape and has a rotation axis along its central axis. The pair of drums 11 are arranged facing each other with a gap between them. In this embodiment, the rotation axes of the pair of drums 11 are parallel to each other.

[0011] Here, "parallel" as used in this specification includes not only cases where two lines, sides, surfaces, etc. do not intersect even when extended, but also cases where the angle between the two lines, sides, surfaces, etc. is within a range of 10°. The rotation axes of the pair of drums 11 according to this embodiment are parallel to each other, but in the present invention, the rotation axes of the drums 11 do not necessarily have to be parallel to each other.

[0012] The diameters of the pair of drums 11 are the same. However, in the present invention, the diameters of the pair of drums 11 may be different. The motors 13 apply a rotational force to the drums 11. The pair of motors 13 correspond one-to-one to the pair of drums 11. The output shaft of each motor 13 is connected to the corresponding drum 11 via a power transmission member such as a belt.

[0013] In the capstan device 1 according to this embodiment, the wire 7 is wound around the upper end of one drum 11, the upper end of the other drum 11, the lower end of the other drum 11, the lower end of the one drum 11, and the upper end of the one drum 11, in that order, as shown in Fig. 1. The wire 7 is wound repeatedly around the drum 11 in the axial direction, as shown in Fig. 2. In this specification, this method of winding the wire 7 is sometimes referred to as a "circumferential method."

[0014] The wire 7 wound around the pair of drums 11 is irradiated with an electron beam by, for example, an electron beam irradiation device 2. The electron beam irradiation device 2 has an opening below a scanning tube 21 covered with an electron beam irradiation window foil 22. The area below the electron beam irradiation window foil 22 is an electron beam irradiation region, which is located between the pair of drums 11 as shown in FIG. 1. This allows the entire length of the wire 7 to be irradiated with an electron beam by irradiating the wire 7 wound around the pair of drums 11 with an electron beam while moving the wire 7.

[0015] (Wire winding device 3) As described above, the wire winding device 3 is a device that winds the wire 7 around a pair of opposing drums 11. The wire winding device 3 according to this embodiment can wind the wire 7 around the pair of drums 11 in a circumferential manner. As shown in FIG. 3 , the wire winding device 3 includes a holding unit 31 and a moving mechanism 4 that moves the holding unit 31. The moving mechanism 4 includes an elongated member 42 to which the holding unit 31 is fixed, and a pair of rotating members 41 that move the elongated member 42.

[0016] (Holding part 31) The holding portion 31 holds one end of the wire 7. As shown in FIG. 4, the holding portion 31 is fixed to the elongated member 42 and moves in accordance with the movement of the elongated member 42. In this embodiment, the holding portion 31 is provided on one of the widthwise edges (direction perpendicular to the movement direction) of an outer plate 421 of the chain, which is the elongated member 42. The holding portion 31 is formed of a plate (top plate) that is approximately perpendicular to the outer plate 421. However, the position at which the holding portion 31 is provided is not limited to the widthwise edge of the outer plate 421, and may be, for example, the center of the widthwise direction of the outer plate 421 or the inner plate 422.

[0017] The holding portion 31 has an attachment portion 32 to which one end of the wire 7 is attached. The attachment portion 32 may be any portion capable of holding one end of the wire 7, and may be, for example, a hole, a pin, a notch, a groove, or the like. The attachment portion 32 according to this embodiment is a pair of holes. The wire 7 is attached to the pair of holes by passing one end of the wire 7 through the holes. Note that the attachment portion 32 may also be configured as a fixing hole such as a screw hole to which a fixing device such as a screw is attached to one end of the wire 7. The "one end" referred to here may be near the longitudinal end of the wire 7, and a part of the wire 7, including the end, may protrude from the attachment portion 32.

[0018] (Moving mechanism 4) The moving mechanism 4 moves the holding part 31 along a fixed path. As described above, the moving mechanism 4 includes a pair of rotating members 41 and an elongated member 42. The "path" here refers to a path along the planned winding position of the wire rod 7 when the pair of drums 11 are viewed along the rotation axis direction (when the pair of drums 11 are viewed from outside the rotation axis direction). The "planned winding position of the wire rod 7" refers to a designed position where the wire rod 7 will be placed when the wire rod 7 is wound around the pair of drums 11. The "planned winding position of the wire rod 7" includes both a case where the wire rod 7 is not actually wound around it and a case where the wire rod 7 is actually wound around it.

[0019] The rotating member 41 has a rotation axis that is parallel to the rotation axis of the drum 11. The rotation axis of the rotating member 41 according to this embodiment is positioned coaxially with the rotation axis of the drum 11. The rotating member 41 rotates integrally with the drum 11.

[0020] Here, "coaxially with the rotation shaft of the drum 11" refers not only to the case where the rotation member 41 is attached to the rotation shaft of the drum 11, but also to the case where the rotation shaft of the rotation member 41 is on an extension of the rotation shaft of the drum 11. When the rotation shaft of the rotation member 41 is on an extension of the rotation shaft of the drum 11, for example, the rotation shaft of the drum 11 and the rotation shaft of the rotation member 41 are connected via a coupling.

[0021] Examples of the rotating member 41 include a sprocket, a pulley, and a sheave. The rotating member 41 according to this embodiment is a sprocket. The outer diameter of the rotating member 41 (the diameter of the tip circle of the sprocket) is preferably equal to or larger than the outer diameter of the drum 11, but may be smaller than the outer diameter of the drum 11.

[0022] The elongated member 42 is moved along a path by the pair of rotating members 41. The elongated member 42 is formed endless and wound around the pair of rotating members 41. Therefore, the path of the holding unit 31 sequentially connects the upper end of one rotating member 41, the upper end of the other rotating member 41, the lower end of the other rotating member 41, the lower end of one rotating member 41, and the upper end of the one rotating member 41. As described above, the path is aligned with the intended winding position of the wire 7 when the drum 11 is viewed along the rotation axis direction. In this embodiment, the outer diameter of the drum 11 and the outer diameter of the rotating member 41 are substantially the same, so the path overlaps with the intended winding position of the wire 7 when the drum 11 is viewed along the rotation axis direction. However, depending on the relationship between the outer diameter of the drum 11 and the outer diameter of the rotating member 41, the intended winding position of the wire 7 may not overlap with the path. Note that the "path" referred to here merely describes the shape of the path and does not specify the direction in which the elongated member 42 moves.

[0023] Here, "endless" means that both ends of a long member in the longitudinal direction are connected to form a ring. Examples of the long member 42 include power transmission members such as chains, timing belts, V-belts, wires, and strings. The power transmission member here refers to a member that can transmit an external force applied along the longitudinal direction to one part of the long member 42 to another part. The long member 42 according to this embodiment is a chain with rollers (center roller chain). However, the chain is not limited to a chain with rollers, and may be, for example, a roller chain, a chain with side rollers, or the like.

[0024] When the motor 13 (see FIG. 1) of each drum 11 rotates, the drum 11 rotates, which in turn rotates the pair of rotating members 41. When the pair of rotating members 41 rotates, the elongated member 42 moves in response, and the holding portion 31 moves along the path.

[0025] As the holding parts 31 move along the path, one end of the elongated member 42 held by the holding parts 31 is pulled and moves, as shown in Figures 5(A) and 5(B). As the drums 11 continue to rotate and the holding parts 31 continue to move, the wire 7 can be wound around the pair of drums 11, as shown in Figures 5(C) to 5(E).

[0026] If the wire 7 begins to bias toward one end of the drum 11 in the direction of the rotation axis, the motor 13 of the drum 11 can be stopped temporarily, and the worker can move the wire 7 toward the other end of the drum 11 in the direction of the rotation axis.

[0027] <Modification> The above embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. Modifications of the embodiment are listed below. The modifications described below can be applied in appropriate combinations.

[0028] (Variation 1) As shown in Fig. 6, the wire winding device 3 according to this modified example differs from the above embodiment in that it has an axial direction drive unit 5 that moves the rotating member 41 and the elongated member 42 in a direction along the rotation axis of the drum 11. In the following, common members are given the same reference numerals and redundant explanations will be omitted, and differences will be mainly described.

[0029] The long member 42 is an endless roller chain. The roller chain is wound around the pair of drums 11, passing through the upper end of one drum 11, the upper end of the other drum 11, the lower end of the other drum 11, the lower end of the one drum 11, and the upper end of the one drum 11 in that order. As shown in FIG. 4 , the roller chain has a center roller 423 whose diameter is greater than the width of the inner plate 422 and the width of the outer plate 421. This allows the roller chain to move in the circumferential direction of the pair of drums 11. The roller chain also contacts the drum 11 at its rollers. Therefore, because the contact area is small, the roller chain can also move in the direction along the rotation axis of the drum 11.

[0030] Examples of materials for the roller include metal, nylon, and fluororesin. Among these, nylon or fluororesin is preferably used from the viewpoint of slipperiness.

[0031] The rotating member 41 moves the elongated member 42. The rotation axis of the rotating member 41 is parallel to the rotation axis of the drum 11, but differs from the above embodiment in that it is not coaxial with the rotation axis of the drum 11. In other words, the rotation axis of the rotating member 41 is parallel to the rotation axis of the drum 11, but is at a different position from the rotation axis of the drum 11.

[0032] The rotating member 41 is rotated by a motor 52 separate from the motor 13 that rotates the drum 11. There may be one rotating member 41 or two or more rotating members 41 as long as they can move the elongated member 42. When there are two or more rotating members 41, a motor 52 is attached to each rotating member 41.

[0033] When two rotating members 41 are provided, it is preferable that the central axes of the two rotating members 41 and the central axes of the two drums 11 are located on the same plane, that is, the two drums 11 are disposed between the two rotating members 41. This makes it possible to compensate for the rotational force of the elongated member 42, and by providing an axial direction drive unit 5 (described later) for both rotating members 41, it becomes easy to translate the elongated member 42 in the direction of the rotation axis.

[0034] As described above, the axial direction driving unit 5 moves the rotating member 41 and the elongated member 42 in a direction along the rotation axis of the drum 11. As shown in Fig. 6, the axial direction driving unit 5 includes a slider 51 that supports the rotating member 41, and a guide unit 53 that moves the slider 51 in a direction parallel to the rotation axis.

[0035] The guide unit 53 includes a guide 54 extending in a direction parallel to the rotation axis of the drum 11, and a drive unit 55 that drives the slider 51 to move along the guide 54. The guide 54 according to this embodiment is a ball screw, and the drive unit 55 is a motor. However, the guide unit 53 is not limited to a structure including a ball screw and a motor, and may be, for example, a linear actuator using a linear bushing, a linear guide, a rack and pinion, a plurality of pulleys and a timing belt, a plurality of gears and a drive chain, a cylinder, a telescopic structure, or the like.

[0036] The slider 51 may be provided with position restriction units that move the elongated member 42 in the axial direction in accordance with the movement of the slider 51. The position restriction units are, for example, located on both sides of the elongated member 42 in the rotation axis direction, and move in accordance with the movement of the slider 51, thereby moving the elongated member 42 in the axial direction.

[0037] The wire winding device 3 of this modified example has one axial drive unit 5, but as described above, if it has two or more rotating members 41, it may have two or more axial drive units 5 corresponding to each of the rotating members 41.

[0038] Next, the operation will be described. First, the long member 42 is wound around any part (preferably an end) of the drum 11 in the direction of the rotation axis. In this state, when the motor 52 is operated, the rotating member 41 rotates, and in response, the long member 42 moves, and the holding part 31 moves along the path. When the holding part 31 moves along the path, one end of the long member 42 held by the holding part 31 is pulled and moves.

[0039] While moving the elongated member 42, the axial drive unit 5 moves the rotating member 41 and the elongated member 42 along the rotation axis direction of the drum 11. As a result, the wire 7 wound around the drum 11 is arranged at different positions in the rotation axis direction of the drum 11, thereby reducing overlapping of the wire 7 wound around the drum 11.

[0040] The speed at which the slider 51 is moved by the axial drive unit 5 may be set arbitrarily by the user. The speed at which the slider 51 is moved by the axial drive unit 5 may be set according to the pitch in the rotational axis direction of the wire wound around the drum 11. Note that a common motor may be used as the motor that drives the rotating member and the drive device for the guide unit. In this case, the speed at which the slider 51 is moved cannot be varied, but there is a cost advantage in that the number of motors can be reduced.

[0041] (Variation 2) In the wire winding device 3 according to the above embodiment, the wire 7 is wound around a pair of drums 11 in a circumferential manner. However, in this modified example, as shown in FIG. 7 , the wire 7 can be wound around a pair of drums 11 in a cross-winding manner (sash-winding manner). The cross-winding manner means a manner in which the wire 7 is wound so as to pass through the upper end of one drum 11, the lower end of the other drum 11, the upper end of the other drum 11, and the lower end of one drum 11. By winding the wire 7 around the pair of drums 11 in the cross-winding manner, when passing through the electron beam irradiation area, the wire 7 can be moved so that its back surface faces the electron beam irradiation window foil 22, and then moved so that its front surface faces the electron beam irradiation window foil 22, allowing both sides of the wire 7 to be appropriately irradiated with the electron beam.

[0042] As shown in FIG. 8, the wire winding device 3 according to this modified example includes a pair of rotating members 41, an elongated member 42, and a guide rail 6.

[0043] As shown in Fig. 9, the long member 42 is formed in a shape having ends on both sides in the longitudinal direction. The long member 42 according to this embodiment is a roller chain. The long member 42 is configured to be deformable in a direction intersecting the longitudinal direction of the long member 42 on an imaginary plane perpendicular to the rotation axis of the drum 11.

[0044] The rotating member 41 has a rotation axis parallel to the rotation axis of the drum 11. The rotation axis of the rotating member 41 according to this embodiment is positioned coaxially with the rotation axis of the drum 11. The rotating member 41 rotates integrally with the drum 11. The rotating member 41 according to this modified example is a sprocket. The rotating member 41 is rotatably attached to the guide rail 6.

[0045] The guide rail 6 has a recess 61 that forms a path for the elongated member 42. The recess 61 is a cross-shaped passage that connects the upper end of the rotating member 41 corresponding to one drum 11, the lower end of the rotating member 41 corresponding to the other drum 11, the upper end of the rotating member 41 corresponding to the other drum 11, the lower end of the rotating member 41 corresponding to one drum 11, and the upper end of the rotating member 41 corresponding to the one drum 11. The depth and width of the recess 61 are formed to a size that can accommodate the elongated member 42. The elongated member 42 can move while being guided along the recess 61. That is, in this modified example, the recess 61 forms a path. Note that the description of the path here merely describes the shape of the path and does not specify a single direction in which the elongated member 42 moves.

[0046] The material of the guide rail 6 is not particularly limited, and examples thereof include metal, synthetic resin, carbon, rubber, fabric, and pulp, but synthetic resin is preferable from the viewpoint of the slidability and strength of the elongated member 42. Furthermore, when the guide rail 6 is made by processing a metal to form the recess 61, the inner surface of the recess 61 may be coated to improve slidability.

[0047] 9(A), when two non-parallel tangent lines are drawn to a pair of rotating members 41, the points of contact are T1, T2, T3, and T4, and the intersection of the two tangent lines is X1. If the length from X1, T1, T2, and X1 is L1, and the length from X1, T3, T4, and X1 is L2, each of the lengths L1 and L2 must be longer than the length between T2 and T3 (the length between T4 and T1). This prevents interference between the elongated members 42 even when they move along the path.

[0048] When the motor 13 of each drum 11 rotates, one drum 11 rotates in the forward direction and the other drum 11 rotates in the reverse direction. The pair of rotating members 41 rotate in accordance with the rotation of the drums 11. When the pair of rotating members 41 rotate, the long member 42 moves in response, and as shown in Figure 9(A), the long member 42 is suspended between the lower end of one rotating member 41 and the upper end of the other rotating member 41.

[0049] As the rotation of the rotary members 41 continues, the elongated member 42 meshes with only one of the rotary members 41, as shown in FIG. 9(B), and then is bridged between the upper end of one rotary member 41 and the lower end of the other rotary member 41. In this way, the elongated member 42 moves along the path. As a result, the holding portion 31 moves along the cross-hitch path.

[0050] As the holding parts 31 move along the path, one end of the elongated member 42 held by the holding parts 31 is pulled and moved. As the drums 11 continue to rotate and the holding parts 31 continue to move, the wire 7 can be wound around the pair of drums 11 in a cross-wound state, as shown in FIG.

[0051] (Variation 3) As shown in Fig. 10, the wire winding device 3 according to this modification is the same as the modification 2 in that it winds the wire 7 around a pair of drums 11 in a cross-winding manner, but differs from the modification 2 in that it has an axial drive unit 5. In the following, common members are given the same reference numerals and redundant explanations will be omitted, and differences will be mainly described.

[0052] As shown in FIG. 10, the wire winding device 3 according to this modified example includes a pair of rotating members 41, a long member 42, a guide rail 6, and a pair of axial direction driving units 5.

[0053] The long member 42 is a roller chain, as in the first modification. The roller chain moves along a path on the surface of the drum 11. As shown in Fig. 11, the roller chain moves along a cross-shaped path that sequentially connects the upper end of one drum 11, the lower end of the other drum 11, the upper end of the other drum 11, the lower end of one drum 11, and the upper end of the one drum 11. Note that the direction in which the long member 42 moves along this path is not limited to one direction.

[0054] The rotating member 41 moves the elongated member 42. The rotation axis of the rotating member 41 is parallel to the rotation axis of the drum 11, but is not coaxial with the rotation axis of the drum 11. In other words, the rotation axis of the rotating member 41 is parallel to the rotation axis of the drum 11, but is at a different position from the rotation axis of the drum 11. As shown in FIG. 10 , the rotating member 41 is rotated by a motor 52 that is separate from the motor 13 that rotates the drum 11.

[0055] The guide rail 6 is formed with a pair of holes 62 through which the drums 11 pass. The pair of holes 62 penetrate the guide rail 6 and are connected at the center of the guide rail 6. A drum 11 passes through each hole 62, and the space between the inner surface of the hole 62 and the drum 11 forms a path for the elongated member 42 (i.e., the path of the holding portion 31). The passage between the inner surface of the hole 62 and the drum 11 is formed in a cross shape so as to connect the upper end of one drum 11, the lower end of the other drum 11, the upper end of the other drum 11, the lower end of one drum 11, and the upper end of one drum 11 in that order. Therefore, the elongated member 42 can move while being guided within the passage.

[0056] The axial driving unit 5 moves the guide rail 6 together with the rotating member 41 and the elongated member 42 in a direction along the rotation axis of the drum 11. As shown in Fig. 10, the axial driving unit 5 includes a slider 51 that supports the rotating member 41, and a guide unit 53 that moves the slider 51 in a direction parallel to the rotation axis. Note that the configuration of the axial driving unit 5 is the same as that of the first modified example, and therefore a description thereof will be omitted.

[0057] First, the elongated member 42 is placed at any part (preferably an end) in the rotational axis direction of the drum 11. When the motor 52 is operated in this state, the rotating member 41 rotates, as shown in Figures 11(A) and 11(B), and accordingly, the elongated member 42 moves, and the holding part 31 moves along the path. When the holding part 31 moves along the path, one end of the elongated member 42 held by the holding part 31 is pulled and moves.

[0058] While moving the elongated member 42, the axial direction drive unit 5 moves the guide rail 6 along the rotation axis direction together with the rotating member 41 and the elongated member 42. This causes the wire 7 wound around the drum 11 to be positioned at different positions in the rotation axis direction of the drum 11, thereby reducing overlapping of the wire 7 wound around the drum 11.

[0059] (Other variations) In the above embodiment, the retaining portion 31 was a top plate provided on the outer plate 421 of the chain, but the present invention is not limited to this and may be, for example, a hole provided in the outer plate 421 or the inner plate 422.

[0060] In the above embodiment, the rotating member 41 is configured to rotate integrally with the drum 11 by connecting the rotating shaft of the rotating member 41 to the rotating shaft of the drum 11, but for example, a separate motor may be provided to drive the rotating member 41. In this case, the rotation speed of the rotating member 41 may be set to be approximately the same as the rotation speed of the drum 11, so that the rotating member 41 and the drum 11 rotate in synchronization.

[0061] The guide rails according to the second and third modifications are configured by processing a single member, but may also have a divided structure.

[0062] In this specification, expressions accompanied by "approximately" such as "almost perpendicular" may be used. For example, "almost perpendicular" means that the angle is essentially "orthogonal," and does not necessarily mean that the angle is strictly 90°, but also includes an error of about ±10°. The same applies to other expressions accompanied by "approximately."

[0063] Furthermore, in this specification, expressions such as "end" and "edge" are used that are distinguished by the presence or absence of "... part." For example, "edge" means the end of an object, while "edge" means a region having a certain range that includes the "edge." Any point within a certain range that includes the edge is considered to be an "end." The same applies to other expressions that include "... part."

[0064] <Effects> As described above, the wire winding device 3 according to the first embodiment is a wire winding device 3 that winds the wire 7 around a pair of opposing drums 11. The wire winding device 3 includes a holding unit 31 that holds one end of the wire 7, and a moving mechanism 4 that moves the holding unit 31 along a path that follows a planned winding position of the wire 7 to be wound around the pair of drums 11, when the pair of drums 11 are viewed along the rotation axis direction.

[0065] According to this embodiment, the moving mechanism 4 can move the holding part 31 that holds the end of the wire 7 along a path, thereby reducing the labor required for the work compared to when an operator manually wraps the wire 7.
