[0009] Preferred embodiments of the present invention will be described below with reference to the drawings.

[0010] Figures 1 and 2 show the spiral protector winding device 100. In Figures 1 and 2, the spiral protector winding device 100 is positioned on a frame 110. As shown in Figures 1 and 2, the spiral protector winding device 100 is a device that winds a spiral protector 130, which is made of a resin tube cut into a spiral shape, onto a rubber hose 120. The rubber hose 120 has layers of rubber. The spiral protector 130 is cylindrical in shape and is made of a resin tube (resin tube) cut into a spiral shape.

[0011] As shown in Figure 2, the spiral protector winding device 100 includes a rubber hose moving device 1, a support base 2, a protector guide 3, a protector holding member 4, a revolving device 5, and a rotating device 6.

[0012] The rubber hose moving device 1 moves the rubber hose 120 being held in a direction that pulls it up. The rubber hose moving device 1 only needs to have the function of pulling up the rubber hose 120 hanging down from the rubber hose moving device 1, and the direction in which the rubber hose 120 that has been pulled up by the rubber hose moving device 1 moves is not limited.

[0013] As shown in Figures 2 and 3, in this embodiment, the rubber hose moving device 1 includes a drive pulley 11, a driven pulley 12, and a pulley drive motor 13 that drives the drive pulley 11. The drive pulley 11, the driven pulley 12, and the pulley drive motor 13 are arranged on a frame 110. The drive pulley 11 and the driven pulley 12 are arranged opposite each other in the radial direction of the rubber hose 120 at a predetermined distance smaller than the outer diameter of the rubber hose 120. The rubber hose moving device 1 lifts the rubber hose 120, which is held between the drive pulley 11 and the driven pulley 12, when the drive pulley 11 is driven by the pulley drive motor 13. However, it is not limited to this, and for example, the rubber hose moving device 1 may have a pair of rollers held at a predetermined distance smaller than the outer diameter of the rubber hose 120.

[0014] The frame 110 has a sliding mechanism 110a on which a driven pulley 12 is disposed. The sliding mechanism 110a is slidable in the direction opposite to the driven pulley 12 and the drive pulley 11 (in the direction of the arrow in Figure 3). This allows switching between a clamped state in which the rubber hose 120 is clamped between the driven pulley 12 and the drive pulley 11, and a released state in which the rubber hose 120 is released. Figure 2 shows the sliding mechanism 110a in the released state. Figure 3 shows the sliding mechanism 110a in the clamped state. At the start and end of the lifting operation by the rubber hose moving device 1, the sliding mechanism 110a on which the driven pulley 12 is disposed can be moved to perform the installation and removal of the rubber hose 120.

[0015] The support base 2 supports the storage case 140 that houses the spiral protector 130. The storage case 140 may be pre-installed on the frame 110, or it may be the case (for example, a cardboard box) that the spiral protector 130 was in when it arrived. In this embodiment, the support base 2 is a circular plate-shaped member. The support base 2 is installed on the frame 110 via a revolving device 5, etc., which will be described later. The support base 2 has a horizontal mounting surface 2a on which the storage case 140 is placed. The mounting surface 2a of the support base 2 is provided with a fastener 2b for fixing the storage case 140. The fastener 2b may be, for example, a hinge.

[0016] The support base 2 is capable of revolving around the rubber hose 120 hanging from the rubber hose moving device 1 while maintaining a horizontal mounting surface 2a. The support base 2 is also capable of rotating on its own axis while maintaining a horizontal mounting surface 2a. The configurations for the revolving and rotating aspects of the support base 2 will be described later.

[0017] The protector guide 3 is pulled out from the housing case 140 (see Figure 2) and serves as a guide for the spiral protector 130 that is wrapped around the rubber hose 120. The protector guide 3 only needs to revolve together with the support base 2 and may be installed on the support base 2 or on a support mechanism on which the support base 2 is provided. In this embodiment, it is provided on a rotating base 51, which will be described later, but is not limited to this.

[0018] Specifically, as shown in FIG. 4, the protector guide 3 of the present embodiment has a pair of rollers 31, 31 and a guide housing 32. The pair of rollers 31, 31 are arranged to face each other at a predetermined interval smaller than the thickness of the spiral protector 130. The pair of rollers 31, 31 sandwich the spiral protector 130 pulled out from the storage case 140 (see FIG. 2) and guide it to the guide housing 32. As shown in the exploded view of FIG. 4, the guide housing 32 is formed in an L shape in top view. The guide housing 32 is formed with a guide groove 32a, a guide hole 32b, and a hose groove 32c. The guide groove 32a is provided along the side of the outer portion of the guide housing 32. The guide hole 32b is provided continuously with the guide groove 32a. The guide hole 32b penetrates to the surface of the guide housing 32 on the side of the rubber hose 120. The hose groove 32c is a groove formed on the surface of the guide housing 32 on the side of the rubber hose 120 and extending in the vertical direction. The rubber hose 120 is fitted into the hose groove 32c. The protector guide 3 is rotated about the rubber hose 120 as the central axis by a revolving device 5 (described later). Thereby, the spiral protector 130 pulled out from the protector holding member 4 (see FIG. 2) and passing through the guide groove 32a and the guide hole 32b is wound around the rubber hose 120 in the hose groove 32c.

[0019] As shown in FIG. 2, the protector holding member 4 is provided for holding the spiral protector 130. The protector holding member 4 is provided to facilitate the pulling out of the spiral protector 130 from the storage case 140 (see FIG. 2). The protector holding member 4 holds the side of the spiral protector 130 that is pulled out in the storage case 140 and holds the spiral protector 130 in a state where it can be easily pulled out.

[0020] Specifically, the protector holding member 4 of the present embodiment is a rod-shaped member that holds the spiral protector 130 when the spiral protector 130 is inserted. Note that the protector holding member 4 is not limited to a rod-shaped member. For example, it may be a box-shaped member that houses the side from which the spiral protector 130 is pulled out, and the spiral protector 130 may be pulled out through a hole formed in the box-shaped member. As shown in FIG. 2, the rod-shaped protector holding member 4 is bent halfway to the opposite side of the rubber hose 120 so that the spiral protector 130 does not move upward on the protector holding member 4 more than necessary.

[0021] The revolving device 5 revolves the support base 2 in the winding direction of the spiral protector 130 in accordance with the movement of the rubber hose 120 by the rubber hose moving device 1. The revolving device 5 revolves the support base 2 around the rubber hose 120 hanging down from the rubber hose moving device 1. The revolving device 5 revolves the support base 2 together with the protector guide 3.

[0022] As shown in Figure 5, in this embodiment, the orbital device 5 comprises a turntable 51, wheels 52, a wheel drive motor 53, a support base connecting member 54, and a support base side pulley 55. The turntable 51 is a disc-shaped plate member. The turntable 51 is rotatably supported by a support member 160, etc. The turntable 51 is provided with a through hole in the center through which a rubber hose 120 is inserted. The position of this through hole coincides vertically with the position where the drive pulley 11 and the driven pulley 12 grip the rubber hose 120 (see Figure 3). The wheels 52 are driven by the wheel drive motor 53. The outer circumferential surface of the wheels 52 is in contact with the lower surface of the turntable 51. When the wheels 52 are driven by the wheel drive motor 53, the turntable 51 is rotated by friction between the outer circumferential surface of the wheels 52 and the lower surface of the turntable 51. The support base connecting member 54 is a plate-shaped member for connecting the rotating base 51 and the support base 2. The support base side pulley 55 is a pulley provided on the upper surface of the tip of the support base connecting member 54. The support base side pulley 55 is provided on the lower surface of the support base 2 so as to be at the position of the axis of rotation of the support base 2. The support base side pulley 55 is rotatably provided with respect to the support base connecting member 54.

[0023] In this way, the turntable 51 is rotated by the drive of the wheels 52 by the wheel drive motor 53. As the turntable 51 rotates, the support base 2, which is connected to the turntable 51 by the support base connecting member 54 and the support base side pulley 55, revolves around the turntable 51. Since the central axis of the turntable 51 is the position of the rubber hose 120 hanging down from the rubber hose moving device 1, the support base 2 revolves around the rubber hose 120 hanging down from the rubber hose moving device 1. The protector guide 3 rotates along with the revolving support base 2, and the spiral protector 130 is wrapped around the rubber hose 120.

[0024] Furthermore, as shown in Figure 5, in this embodiment, the rotation device 6 comprises a turntable-side pulley 61, a connecting belt 62, and a support base-side pulley 55. The turntable-side pulley 61 is fixed to the central axis of the turntable 51. The rotation of the turntable 51 is transmitted to the support base-side pulley 55 by the connecting belt 62, and the support base 2 rotates together with the support base-side pulley 55. At this time, the direction of rotation of the support base 2 is opposite to the winding direction of the spiral protector 130.

[0025] It is preferable that the orbital period of the orbital device 5 and the rotational period of the rotational device 6 match by adjusting the diameters of the support base side pulley 55 and the turntable side pulley 61. Furthermore, by matching the orbital period and the rotational period with the movement speed of one pitch by the rubber hose moving device 1, the spiral protector 130 can be wrapped around the rubber hose 120 without gaps or overlaps.

[0026] The spiral protector winding device 100 according to one embodiment of the present invention has been described above. The following technical features of the spiral protector winding device 100 have been disclosed as described above.

[0027] As shown in Figure 2, the spiral protector winding device 100 of this embodiment includes a rubber hose moving device 1 that moves the rubber hose 120 to be clamped in an upward direction, a support base 2 that supports a housing case 140 that houses a spiral protector 130, which is shaped like a spirally cut resin tube, and a protector guide 3 that serves as a guide for the spiral protector 130 as it is pulled out from the housing case 140 and wound around the rubber hose 120. Furthermore, as shown in Figure 5, the device includes a revolving device 5 that revolves the support base 2 together with the protector guide 3 in the winding direction of the spiral protector 130 around the rubber hose 120 hanging down from the rubber hose moving device 1, and a rotation device 6 that rotates the support base 2 in the opposite direction to the winding direction in accordance with the revolving of the support base 2.

[0028] With the above configuration, the rubber hose 120 is moved so as to be lifted by the rubber hose moving device 1, while the support base 2 revolves around the rubber hose 120 together with the protector guide 3. As a result, the protector guide 3 installed on the support base 2 rotates around the rubber hose 120, lifting the rubber hose 120 while continuously winding the spiral protector 130 out of the storage case 140. Furthermore, the rotation of the support base 2 causes the spiral protector 130, whose diameter is tightened when it is pulled out of the storage case 140, to rotate in a direction that loosens its diameter. As a result, even a long spiral protector 130 can be automatically, easily, and neatly wound around a long rubber hose 120.

[0029] Furthermore, as shown in Figure 2, the spiral protector winding device 100 of this embodiment further includes a protector holding member 4 that holds the spiral protector 130, and the spiral protector 130 pulled out from the protector holding member 4 is guided onto the rubber hose 120 by a protector guide 3.

[0030] According to the above configuration, the spiral protector 130 can be easily removed from the storage case 140 (see Figure 2).

[0031] Although embodiments of the present invention have been described above, these are merely illustrative examples and do not particularly limit the present invention. Specific configurations and other aspects can be modified as appropriate. Furthermore, the actions and effects described in the embodiments of the invention are merely a list of the most preferred actions and effects resulting from the present invention, and the actions and effects according to the present invention are not limited to those described in the embodiments.
