Abstract

PROBLEM TO BE SOLVED: To prevent a hose from entanglement when it is taken up on a hose winding device. SOLUTION: A hose guide 5 installed on the frame of a hose winding device has a guide hole 12 whose inner diameter enlarges from the rear end face to the front, and in the front part, a conical flange 11 is provided, while a ring- shaped rib 13 is formed at the edge of the front face opening of the guide hole 12. When the hose is twisted and a loop is formed, the looped part contacts with the front face of the flange 11 when the hose is being taken up, and the rib 13 intrudes into the hose intersecting part. If a further winding is made, the looped part moves outward along the inclined surface of the flange 11 and goes out of the flange 11 to cause the loop to be opened and drawn in through the guide hole 12 to be wound on a drum.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose guide provided in a hose winding device, and more particularly, to a hose guide of a hose winding device for preventing the hose from being entangled when winding the hose. .

[0002]

2. Description of the Related Art In a hose winding device such as an air hose or a watering hose connecting an air compressor and a pneumatic tool, an annular hose guide is provided to uniformly wind the hose. Things are known. The hose guide mounted on the frame supporting the drum can be moved parallel to the axial direction of the drum, and the hose is pulled out of the hose winding device through the guide hole of the hose guide. When winding the hose, the hose guide can be reciprocated in the axial direction of the drum while rotating the hose winding device, so that the hose can be spirally aligned around the drum and wound.

However, when the hose is pulled out from the hose winding device and used, the work site is often pulled around and twisted. If the hose is wound while it is twisted, the same applies to linear and threaded materials other than the hose.However, as the hose is wound around the drum, a phenomenon occurs in which a loop is gradually formed due to the twist. When the loop reaches the position of the hose guide, the folded hose becomes clogged in the hole of the hose guide and cannot be wound. In such a state, the hose must be twisted to break the loop, and the hose loop must be often broken during the winding operation.

Therefore, even if the hose has a loop shape, there arises a technical problem to be solved in order to improve the handleability of the hose winding device so that the hose can be smoothly wound around the hose winding device. It is an object of the present invention to solve the above problems.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object, and has an annular or cylindrical hose guide which is mounted on a frame of a hose winding device and serves as a guide for taking in and out a hose. A horn-shaped guide hole whose inner diameter increases from the rear end face to the front end face of the hose guide, and a conical flange centered on the guide hole is provided at the front of the hose guide, and a front face of the guide hole is provided. An object of the present invention is to provide a hose guide for a hose winding device, wherein an opening edge is raised to form an annular rib portion.

Air hoses 7 and 8 are connected respectively. The air hose 7 connected to the air plug is wound around the drum 4, and the air hose 8 connected to the rotary joint is connected to an air compressor (not shown).

The air hose 7 wound around the drum 4 is pulled out through a guide hole of the hose guide 5 and is
An air socket 9 to be fitted to an air plug of a pneumatic tool is mounted at a tip end of the pneumatic tool. The high-pressure air of the air compressor is supplied to a pneumatic tool connected to the air hose 7 through an air hose 8, a rotary joint, a relay pipe, and the air hose 7.

FIGS. 2 and 3 show a hose guide 5, which is a trumpet-shaped member having a flange portion 11 formed at the front of a cylindrical portion 10, and an exponential horn-type guide whose inner diameter increases toward the front. A hole 12 is formed. The inner diameter of the guide hole 12 is slightly larger than the outer diameter of the air hose 7 at the rearmost minimum diameter part, and the maximum diameter part at the front end is suitably about two to three times the air hose 7.

The front surface of the flange portion 11 has a low conical shape slightly receding toward the outer periphery, and has a simple conical shape or a concave curved cross-sectional shape as shown in FIG. As shown in FIG. 3, a convex curved surface cross section may be used. Also. The opening edge of the guide hole 12 on the front surface protrudes forward to form an annular rib portion 13.

By inserting the rear cylindrical portion 10 between the upper frame 2a and the guide frame 2b, and attaching the guide ring 14 and the retaining ring 15 to the rear portion of the hose guide 5,
The upper frame 2a and the guide frame 2b are connected to the flange 1
The hose guide 5 is attached to the pipe frame 2 so as to be slidable in the left-right direction, sandwiched between the guide ring 1 and the guide ring 14. The clearance between the flange portion 11 and the guide ring 14 is slightly larger than the diameter of the upper frame 2a and the guide frame 2b to provide clearance, and the hose guide 5 can swing in a certain angle range. It is configured as follows.
