Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is intended to rotate a flexible long material such as an electric wire or a wire rope around a shaft thereof when the flexible long material is wound around the drum. Regarding rotating machines.

(Prior Art) Conventionally, there is a rotary machine of the above-mentioned drum configured as follows.

According to this, the rotating machine has a supporting base, and a pair of left and right rotating wheels is supported by the supporting base in a front view. A drum around which the flexible long material is wound can be placed on both of the rotating wheels. At least one of the two rotary wheels is a drive wheel that is interlocked with an electric motor, and the drum is interlocked with the rotational drive of the drive wheel so that the long material can be wound on the drum. .

(Problems to be Solved by the Invention) By the way, in the above-described conventional configuration, when the tension of the long material increases during winding of the long material, the tension causes the drum to unexpectedly roll on the rotating wheels. It may fall.

Therefore, it is conceivable to increase the dimension between the two rotating wheels to increase the fitting dimension of the drum into these rotating wheels.

However, in this case, the drum is fitted in a wedge shape between both rotary wheels, and the pressure contact force between each rotary wheel and the drum is increased, so that it is necessary to increase the force for rotationally driving the drive wheels. There is a problem.

Further, in particular, when the winding amount of the long material on the drum is small, the drum is light, so when the drum is rotated by the rotation of the drive wheel, the pressure contact force between them is reduced, and the drive wheel slides on the drum. As a result, the drum may not be able to achieve a predetermined rotation.

(Object of the Invention) The present invention has been made by paying attention to the above circumstances, and even if the dimension between both rotary wheels on which the drum is mounted is reduced to some extent, the drum is suddenly moved from above the both rotary wheels. To prevent the drive wheel of the two rotating wheels from slipping on the drum so that a predetermined rotation corresponding to the rotation of the drive wheel can be obtained on the drum. And

(Structure of the Invention) A rotating machine of a winding drum for a flexible long material according to the present invention for achieving the above object is a supporting wheel (rotating wheel) in a front view.
A vertical turning arm 11 is provided between the drive wheel 22 and the driving wheel (rotating wheel) 28, and the lower end of the turning arm 11 is pivoted on the support base 8 so that the upper end side of the turning arm 11 turns left and right. A support rod 16 is provided which is fitted into an inner hole 17 formed on the axis of the drum 2. The support rod 16 is supported by the rotary arm 11 so that the vertical position of the support rod 16 can be adjusted. The support rod 16 can be pressed against the inner peripheral surface of the inner hole 17 by adjusting the vertical position.

(Operation) The operation of the above configuration is as follows.

The terms in parentheses below correspond to the terms in the claims.

The drum 2 is placed on the supporting wheel (rotating wheel) 22 and the driving wheel (rotating wheel) 28, the driving wheel (rotating wheel) 28 is rotationally driven, and the drum 2 is rotated to extend the drum 2. When the strip 1 is wound up, the tension of the strip 1 is large and the supporting wheel (rotating wheel) 22 and the drive wheel (rotating wheel) 28 are wound.
If the drum 2 tries to roll down from above, the drum 2
The pressing force of the support rod 16 against the inner peripheral surface of the inner hole 17 is increased, so that the rolling-down is prevented.

In addition, by adjusting the vertical position of the support rod 16, the inner hole 17
By adjusting the pressure contact force of the support rod 16 with respect to the inner peripheral surface of, the pressure contact force between the drum 2 and the drive wheel (rotating wheel) 28 is adjusted.

Moreover, in the above case, the support rod 16 is the support theory (rotating wheel) 2
2 is supported by a rotary arm 11 located between the drive wheel (rotary wheel) 28 and the rotary wheel 11, and is rotatable left and right as the rotary arm 11 rotates. When pressed against the inner peripheral surface of the drum, this pressure contact force
Is prevented from being largely pressed against one of the support wheel (rotating wheel) 22 and the drive wheel (rotating wheel) 28.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 is a flexible long member that is an electric wire, and 2 is a drum around which the long member 1 is wound.
The drum 2 is made of wood and includes a cylindrical core 3 around which the long member 1 is wound, and disc-shaped collars 4 attached to both ends of the core 3.

Further, 6 is a rotating machine, and this rotating machine 6 rotates the drum 2 around its axis to wind the long material 1 around the drum 2. For convenience of explanation,
The following description will be given with FIG. 1 as a front view of the rotating machine 6 and assuming the direction indicated by the arrow Fr in FIGS. 2 and 3 as the front.

The rotating machine 6 has a support base 8 installed on the work surface 7. Further, the support base 8 has a pedestal 9 and rotating arms 11 pivotally supported by pivot shafts 10 at front and rear ends of the pedestal 9, respectively. It projects toward and is rotatable left and right.

Take-up means 13 is attached to the rotating end of each rotating arm 11. The take-up means 13 is composed of a bearing 14 slidably mounted along the longitudinal direction of the rotating arm 11 and a jack bolt 15 for moving the bearing 14 up and down. And
A support rod 16 having a circular cross section is rotatably supported by the front and rear bearings 14, 14, and the support rod 16 is fitted in an inner hole 17 of the core 3 of the drum 2 on the mount 9.

A pair of front and rear bearings 20, 20 are provided on the right side of the pedestal 9 (which means the direction toward the front, and the same applies hereinafter).
The rotary shaft 21 is rotatably supported by the rotary shaft 21.
A pair of front and rear support wheels 22, 22 that are rotating wheels are externally fitted to the outer peripheral surface 1 so as to be slidable back and forth. Further, each support wheel 22 is provided with a set bolt 23. Then, by loosening the set bolt 23 and sliding the support wheel 22 to a desired position of the rotary shaft 21, and by screwing the set bolt 23 here, the support wheel 22 can be fixed to the desired position of the rotary shaft 21. It has become.

On the other hand, on the left side of the mount 9, a pair of front and rear bearings 26,
A drive shaft 27 is rotatably supported by 26, and a pair of front and rear drive wheels 28, which are rotating wheels, are externally fitted to the drive shaft 27 so as to be slidable forward and backward. In addition, each drive wheel 2
Each set 8 has a set bolt 29. Then, by loosening the set bolt 29 and sliding the drive wheel 28 to a desired position, and screwing the set bolt 29 here, the drive wheel 28 can be fixed to the desired position of the drive shaft 27. .

Then, the drum 2 is placed on each of the supporting members 22 and the driving wheels 28. In this case, the outer peripheral surface 31 of the collar 4 of the drum 2 is joined to the supporting members 22 and the outer peripheral surface of the driving wheels 28. It is supposed to be.

2 to 5, a key groove 32 is formed in the drive shaft 27, and each drive wheel 28 is rotated relative to the drive shaft 27 by a key 33 which is removably fitted in the key groove 32. It has been blocked from moving. Also,
In this case, by pulling out the key 33 from the key groove 32 and loosening the set bolt 29, the drive wheel 28 can rotate relative to the drive shaft 27. Further, spline-shaped teeth 34 are formed on the outer peripheral surface of each drive wheel 28.

A variable speed reduction motor 35 is attached to an upper surface of a rear portion of the gantry 9, and an output shaft of the reduction motor 35 is connected to a rear end of the drive shaft 27 via a coupling 36.

The rotating arm 11 is oriented vertically, and when the rotating machine 6 is viewed from the front as shown in FIG. 1, the rotating arm 11 is located between the support wheel 22 and the drive wheel 28. When the jack bolt 15 of the take-up means 13 is operated, the support rod 16 together with the bearing 14 can be vertically adjusted along the rotating arm 11.

When the long material 1 is to be wound around the drum 2 by the rotating machine 6, first, the support rod 16 is used.
The support rod 16 is lightly pressed against the lower surface of the inner hole 17 formed on the axial center of the drum 2 by adjusting the vertical position of.

Next, when the reduction motor 35 is operated, the drive wheels 28 rotate in the direction of arrow A in FIG. 1 via the drive shaft 27. At this time, the teeth 34 of each drive wheel 28 are engaged with the outer peripheral surface 31 of the collar 4 and the collar 4 is interlocked without slippage, that is, the drum 2 is the same as the arrow B in FIG. Can be rotated in the direction.

Then, the long material 1 is wound around the drum 2 as indicated by an arrow C in FIG.

In the above case, each support wheel 22 normally drives the drum 2 to the drive wheel 2
8 to prevent the drum 2 from rolling down from the drive wheels 28. However, when the drum 2 tries to roll down from the top of the drive wheel 28 to the left due to the tension of the long material 1 to be wound, the support rod 16 causes the inner hole 17 to move.
When the support rod 16 is pressed against the lower surface of the inner hole 17 and the outer peripheral surface 31 of the collar 4 is pressed against each driving wheel 28, the rolling-down is prevented. That is, the support wheels 22 and the support rods 16 are the same as the drive wheels 2
A holding means 37 for holding the drum 2 is constructed on the drum 8.

Further, the press contact of the outer peripheral surface 31 of the collar 4 with the drive wheel 28 more reliably prevents slippage between the outer peripheral surface 31 of the collar 4 and the drive wheel 28. That is, the drum 2 is rotated accurately following the rotation of the drive wheel 28, and an appropriate winding action is obtained.

When the long material 1 wound around the drum 2 is rewound from the drum 2, this rewinding may be performed by reversing the reduction motor 35, but it is performed as follows. You can

That is, the set bolt 29 is loosened and the key groove 32 is
Remove the key 33 from the. Then, each drive wheel 28 can be idled with respect to the drive shaft 27, that is, the drum 2
Can be idled on each support wheel 22 and drive wheel 28. In this way, if the long material 1 is pulled in the direction opposite to the arrow C in FIG. 1, the long material 1 can be rewound.

1 to 3, a drum 2'shown by a chain line in each of the drawings is smaller than the drum 2, and the drum 2'also has a core material 3'and a collar 4 '.

When the long material 1'is wound up by this drum 2 ', each supporting wheel 2 is
2 and the drive wheel 28 may be adjusted to positions that match the dimension between the front and rear collars 4 ', 4'.

In this way, as shown by the arrow C'in FIG. 1, the winding can be performed and the rewinding can be performed in the same manner as described above.

Although the above is based on the illustrated example, the drums 2 and 2'may be made of resin or light metal such as aluminum. Further, instead of forming the teeth 34 on the outer peripheral surface of the drive wheel 28, a member having a large friction coefficient such as rubber is externally fitted to the drive wheel 28 and frictionally joined to the outer peripheral surface 31 of the collar 4. The drum 2 may be rotated. Further, the reduction motor 35 may be an engine.

Further, the rotating machine 6 may be used when applying tension to the long material 1.

(Effect of the Invention) According to the present invention, in a front view, a vertically-oriented rotating arm is provided between the left and right rotating wheels, and the upper end side of the rotating arm is rotated left and right. A lower end of the support rod is pivotally supported, and a support rod fitted in an inner hole formed on the shaft center of the drum is provided. The support rod is supported on the rotating arm so that the vertical position of the support rod can be adjusted. By adjusting the vertical position, the support rod can be pressed against the inner peripheral surface of the inner hole.

Therefore, when the drum is placed on the left and right rotating wheels and the drive wheel in the rotating wheels is driven to rotate to rotate the drum to wind the long material on the drum, If the tension is large and the drum tries to roll down from the left and right rotating wheels, the pressing force of the support rod against the inner peripheral surface of the inner hole of the drum becomes large, and the roll down is prevented.

Therefore, even if the dimension between the left and right rotating wheels on which the drum is placed is reduced to some extent to prevent the drum from being wedged in between them, the drum unexpectedly rolls off from the left and right rotating wheels. Is prevented.

Further, by adjusting the pressure contact force with respect to the inner peripheral surface of the inner hole by adjusting the vertical position of the support rod, the pressure contact force between the drum and the rotating wheel is adjusted.

Therefore, by adjusting the pressure contact force, it is possible to prevent the driving wheel among the rotating wheels from slipping with respect to the drum, and the predetermined rotation corresponding to the rotation of the driving wheel is obtained in the drum.

In addition, in the above case, the support rod is supported by the rotating arm located between the left and right rotating wheels, and can be rotated left and right as the rotating arm rotates. When the drum is pressed against the peripheral surface, the pressure contact force prevents the drum from being largely pressed against one of the left and right rotating wheels.

Therefore, the drum is stably supported by both rotating wheels.
