BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose reel device used for supplying fluids such as oil, water and air.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Laid-Open No. 3-289497, a conventional reel device has a motor with a reducer attached to an upper portion or a lower portion of a main body frame. A rotation transmission mechanism is provided between the rotation shaft of the winding wheel, which is rotatably supported inside the frame, and the winding wheel is driven by the motor with a reducer via the rotation transmission mechanism to wind a hose or the like. And I try to rewind.

[0003]

As described above, the conventional reel device in which the rotary shaft of the motor with reduction gear and the rotary shaft of the winding wheel are separated from each other and the rotary transmission mechanism is provided between them has a large number of parts. However, there are problems that it takes time to assemble and cost reduction is not easy.

The present invention has been made in view of the above circumstances, and provides a hose reel device which is easy to assemble and inexpensive, by simplifying the structure of a hose reel device driven by a motor and drastically reducing the number of parts. The purpose is.

[0005]

According to a first aspect of the present invention, there is provided a hose reel device in which a winding wheel rotatably provided inside a main body frame is driven by a motor to wind a hose. A motor is attached, a winding wheel is concentrically attached to the rotary shaft of the motor, a fluid through hole is bored in the rotary shaft of the motor, and a swivel joint that communicates with one end of the fluid through hole and the other end It is a hose reel device having a structure in which a hose joint communicating with each other is provided.

A second aspect of the present invention is a hose reel device having a structure in which a low speed motor is attached to the inside of the main body frame of the first aspect.

[0007]

According to the first aspect of the invention, the rotation shaft of the motor also serves as the rotation shaft of the winding wheel, and the winding wheel is directly rotated. Fluid is supplied to the hose of the winding wheel via a swivel joint, a fluid passage hole, and a hose joint provided on the rotating shaft of the motor.

According to the second aspect of the present invention, a compact low speed motor that does not require a speed reducing mechanism is mounted inside the main body frame.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

As shown in FIG. 1, a compact low-speed DC motor 12 that does not require a speed reducing mechanism on the inner surface of the main body frame 11 is attached directly by a bolt 14 screwed into its flange portion 13. Has been done. The rotating shaft 15 of this motor 12
Are rotatably borne by a bearing 16 which is penetrated through the main body frame 11 and protruded to the outside and is attached to the main body frame 11. The DC motor 12 is rotated at a low speed of about 30 rpm.

A winding wheel 22 is concentrically attached to a rotary shaft 15 of the motor 12 via a flange 21. In other words, the rotary shaft 15 of the motor 12 is the rotary shaft of the winding wheel 22. The winding wheel 22 has a boss portion 22a and a hose winding concave portion 22b formed by integrating two ashtray discs back to back.

An axial fluid through hole 23 is formed in the rotary shaft 15 of the low-speed DC motor 12, and a swivel joint 24 that communicates with one side of the fluid through hole 23 rotates outside the frame of the rotary shaft 15. A hose joint 25, which is freely fitted and communicates with the other side of the fluid passage hole 23, is radially inserted into the frame of the rotary shaft 15.

As shown in FIG. 2, the swivel joint 24 has a pipe connection port 31 to which an external fluid supply pipe is connected.
An annular groove 33 is communicated with the radial groove 32 through a hole 32 in the radial direction, and a pair of O-rings 34 are fitted to the inner peripheral surfaces on both sides of the annular groove 33. The air-tightness or liquid-tightness between the two is maintained.

Further, the spacer 3 fitted to the rotary shaft 15
5, swivel joint 2 with washer 36 and C-shaped retaining ring 37
The axial position of 4 is determined, and the annular groove 33 of the swivel joint 24 is always communicated with the axial fluid passage hole 23 through the radial hole 38 formed in the rotary shaft 15.

The left end of the fluid passage hole 23 is closed by a plug 39, and the right end is communicated with a hose joint 25 screwed in the radial direction of the rotary shaft 15. One end of a hose wound around the winding wheel 22 is connected to the hose joint 25.

As shown in FIG. 3, a mounting bottom plate 41 is provided in the lower portion of the main body frame 11, and a hose outlet formed by being surrounded by four guide rollers 42 is provided between the side frames. It is provided from the winding wheel 22 to this guide roller.
The hose is pulled out through the hose outlet between 42.

Next, the operation of this embodiment will be described. The rotating shaft 15 of the low-speed DC motor 12 also serves as the rotating shaft of the winding wheel 22 and directly rotates the winding wheel 22 in the forward and reverse directions. Rewind and rewind the hose. At this time, the swivel joint 24 provided on the rotary shaft 15 of the motor 12 supplies fluid to the through hole 23 of the rotary shaft 15 from the outside without rotating, and further, the winding wheel 22 from the hose joint 25.
Supply fluid to hose.

The motor 12 is not limited to an electric motor, but may be a motor that operates by fluid pressure such as air or hydraulic pressure.

[0019]

According to the invention described in claim 1, the rotary shaft of the motor is the rotary shaft of the winding wheel, and the fluid passage hole is bored.
As a mounting shaft for shafts, swivel joints, and hose joints
One rotating shaft of the motor is a versatile member.
Therefore, the structure of the rotating shaft can be simplified and the number of parts can be reduced to provide a hose reel device that is easy to assemble and inexpensive , and the overall width of the device can be made narrower than that of the conventional one.
It is possible to install this hose reel device
There is also the advantage of not taking up space .

According to the second aspect of the present invention, since the low speed motor is compact and does not require a speed reducing mechanism, it can be mounted inside the main body frame, and the size of the device can be reduced.
