DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding and unwinding a linear body such as a hose and a cable.
In particular, the present invention relates to a device having a traverser mechanism and / or a guide pulley attached to a drum.

[0002]

2. Description of the Related Art A traverser mechanism has been used exclusively for aligning and winding a linear body around a drum. Further, a guide pulley has been used to feed the linear body in a predetermined direction.

FIG. 3 shows a drum 21 provided with a traverser mechanism. The traverser mechanism screw-engages a slider 23, which supports a guide roller 24, with a screw shaft 22, and
2 and the drum 21 are linked by a roller chain 25 or a gear, whereby the screw shaft 22 is rotated with the rotation of the drum, and the slider 23 is moved in the axial direction of the drum.

FIGS. 4A and 4B show a guide pulley 9 attached to a drum. A screw shaft 22 is engaged with a frame 11 of the guide pulley 9 by screwing.
The screw shaft 22 is driven to rotate by a motor m via a roller chain 25 or a gear, so that the frame 11 can be moved left and right in front of the drum 1. In that case, the drum motor M
The rotation of the motor m is controlled in accordance with the rotation of the motor m.

[0005]

In the case of a traverser mechanism, a slider for supporting a guide roller on a shaft is screw-engaged with a screw shaft, and the screw shaft is linked by a roller chain or a gear, so that the structure becomes complicated. In the case of the guide pulley, there is a similar problem.In addition, since the rotation of the screw shaft for moving the frame of the guide pulley and the rotation of the drum are performed by separate motors, the rotation control system of the motor is complicated. .

Further, they traverser mechanism and the guide pulley are both guide rollers, guide pulley of Figure 4 in order to align wound linear body drum (A)
As shown in (b), the moving body moves along the axial direction of the drum, and thus the point at which the linear body unwinds constantly changes at large intervals, which usually follows the moving route of the moving body traveling on a fixed track such as a rail. There is a possibility that an excessive force is applied to the linear body and the linear body connecting portion to cause damage.

[0007] The present invention has been made in view of the prior art problems described above, and simplify the mechanism for alignment winding, also linear body having a small deviation of the feeding point of the linear body that passes through the aligned winding mechanism winding taken, it is purpose in providing a rewinding device.

1 (a) and (b) show a first embodiment of a winding and rewinding device for a linear body according to the present invention.

The drum 1 has a spiral guide groove 2 formed on the surface of a winding drum, and a linear body 3 is wound neatly along the guide groove 2. A traverser mechanism 6 and a guide pulley 9 are arranged in front of the drum 1. M is a motor for driving and rotating the drum 1.

The traverser mechanism 6 includes a guide roller 8
A guide 4 which is slidably fitted into the spiral guide groove 2 in the winding drum surface of the drum in a slider 5 for moving the roller. A groove 8b is provided in a base 8a for supporting the guide roller 8 in a shaft, and a pin 7 of the slider 5 is inserted into the groove 8b, so that the slider 5 and the base 8a can be linked to each other within a range where relative rotation is possible. I have.

On the other hand, the guide pulley 9 is shaft-supported so as to be capable of pendulum movement at a position displaced to the linear body feeding side in the frame 11 for supporting the shaft, and 10 is a bearing serving as the fulcrum. Also, such a frame 11
Wheels 12 are mounted on the drum side of the drum so that the pendulum motion of the frame can be performed smoothly.

Thus, the base 8a of the traverser mechanism
Are integrally connected and fixed to the pendulum movement end of the frame 11 on the guide pulley side. Therefore, the frame 11 follows the movement of the slider 5.

In the above-described apparatus, when the linear body 3 wound around the drum 1 is fed out through the guide roller 8 and further through the guide pulley 9, the guide groove 2 of the drum 1, which is rotated together with the feeding, rotates.
The guide 4 guided thereby slides relatively along the spiral of the guide groove 2 and moves along the axial direction of the drum (moves downward in FIG. 1 (a)). The body 3 is moved in accordance with the winding pitch. Based on the movement, the support base 8a engaged with the pin 7 and the concave groove 8b is towed together, and the frame 11 performs a pendulum motion (counterclockwise motion in the drawing) with the bearing 10 as a fulcrum. . At that time, the support base 8a
Is displaced from the slider 5 which is moved along the arc and is moved linearly, because the pin 7 and the groove 8b
And is absorbed by the engaging portion. By such a series of operations, the guide roller 8 guides a portion of the linear body 3 which starts to be fed out of the guide groove 2, and the guide pulley 9 guides the linear body 3 in a linear direction on the extension thereof. The guide pulley is further fed out from the point where the position of the guide pulley hardly changes on the fulcrum side of the pendulum of the frame 11.

On the other hand, when winding the fed linear body around the drum, if the drum 1 is rotated by driving the motor M, the linear body 3 is inserted into the guide groove 2 and the aligned winding is performed. However, in this case, the movement of the traverser mechanism 6 and the guide pulley 9 involves an operation opposite to the above-described rewinding operation.

FIG. 2 shows a second embodiment of the apparatus for winding and rewinding a linear body according to the present invention, and the same parts as those in the above-mentioned embodiment are designated by the same reference numerals.

This embodiment is different from the above-described embodiment in that the traverser mechanism is simplified . That is, the frame 11
A support base 8a of the guide roller 8 is integrally connected and fixed to the pendulum movement end of the
Are directly connected, and the guide is fitted into the spiral guide groove 2 on the drum side. Therefore, in this embodiment, the guide 4 itself is accompanied by an arc movement. Therefore, the guide 4 moves to the axial end of the winding drum surface by designing the spiral guide groove 2 deeply so that the guide 4 enters the groove 2 most deeply at the axial midpoint of the winding drum surface. Even if it does not come off from the groove 2, it is devised. In addition, by moving the bearing 10 as far away from the drum 1 as possible, it is possible to make the circular motion of the guide 4 almost linear. Alternatively, the guide 4 may be linked to the base 8 or the frame 11 so as to be slidable in the longitudinal direction so that the movement of the arc is almost eliminated.

[0019]

The first means and the second means in the apparatus for winding and rewinding a linear body according to the present invention as described above .
According to the second means , the guide is provided in the traverser mechanism , and the guide is slidably fitted into the spiral guide groove on the drum side, so that the guide is rotated in the axial direction of the drum by the rotation of the spiral of the guide groove due to the rotation of the drum. Since the traverser is moved to perform a predetermined traverser movement, a conventional drive mechanism such as a drive motor chain and gears is not required, and a mechanism linkage system can be simplified and economical.

Further, the pendulum is moved about the position where the frame of the guide pulley is displaced to the side where the linear body is fed , and the pendulum movement end side is a traverser mechanism.
To the guide roller shaft support base at
By this, the guide pulley is displaced on the extension of the linear object unwinding start point and smoothly guides the linear object,
The linear body can be fed out from the point without fulcrum That position change most of the pendulum motion of the guide pulley to the outside, there in the mobile can not be axially against the displacement of the drum, for example, by traveling a certain trajectory Even in this case, the linear body and the linear body connecting portion can be moved without excessive force.
