Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a winding drum device for winding a long body such as a hose or an electric wire cable.

[Conventional technology]

Conventionally, when winding a long body such as a rubber hose or an electric wire cable, a winding drum having side plates on both sides of a body portion is arranged with its rotation axis horizontal, and the long body is rotated while rotating the winding drum. Were aligned in a plurality of stages and a plurality of rows using a traverse device and wound on the body portion, and then a plurality of positions of this winding bundle were bound by binding bands.

However, in the conventional winding drum, in order to easily take out the winding bundle of the long body from the winding drum, the body portion is formed in a cylindrical shape with a taper or is described in JP-B-45-6368. Since the taper is provided by reducing the diameter of one end of the body when taking out the winding bundle, the long body easily slips to the smaller diameter side of the body, and the winding shape to be aligned during winding is disturbed. In addition, when the take-up bundle of the long body is taken out, the aligned long bodies are easily collapsed.

Further, although there is one in which the body of the winding drum can be folded to be small, the mechanism of the body is complicated, and folding work by the operator is troublesome, and there is a drawback that it takes time.

[Problems to be solved by the device]

In view of such a conventional situation, the present invention can align and wind long members at the time of winding, and can easily take out the long members aligned and wound without breaking the winding bundle. An object of the present invention is to provide a winding drum device having a long body.

[Means for solving the problem]

To achieve the above object, in the take-up drum device of the present invention, the respective rotary shafts are arranged so as to face each other in a straight line, and at least one of them is provided so as to be movable in the rotary shaft direction.
One side plate, a cylindrical body part that is divided into a plurality of divided body parts along the rotation axis direction between the two side plates, and a rotary shaft of one side plate facing each divided body part. A plurality of air cylinders, which are fixed and are connected to each of the divided body parts by drive rods, are provided, and the divided body parts are radially moved by the plurality of air cylinders to expand the diameter of the body part as a whole. Alternatively, the diameter can be reduced.

〔Example〕

 A specific example of the device of the present invention will be described with reference to the drawings.

The first side plate 2a is provided on the upper end of the pillar 1 which is vertically erected on the base.
Are rotatably supported by bearings 14 with the rotating shaft 3a horizontal. In addition, a movable frame 4 is provided on the base so as to face the pillar 1.
Is movably supported in the direction of the first rotating shaft 3a of the first side plate 2a, and the second side plate 2b is attached to the movable frame 4 by the second rotating shaft 3a.
The bearing 3 is rotatably supported horizontally by a bearing 15 so that 3b faces the first rotating shaft 3a of the first side plate 2a in a straight line. Both side plates 2a and 2b are adapted to rotate in the same direction at the same speed by a driving device (not shown).

Protrusions 3c are provided on the side of the second side plate 2b of the first rotating shaft 3a of the first side plate 2a, and four air cylinders 5 are fixed to the protrusion 3c at equal intervals in the circumferential direction. The driving rod 6 of each air cylinder 5 extends in the radial direction of the side plates 2a, 2b, and the cylindrical body portion 7 of the winding drum is divided into four parts along the direction of the rotation shafts 3a, 3b at the tip thereof. The body portions 7a and 7b are fixed to each other. The air pipe of each air cylinder 5 has a rotating shaft 3a.
Is connected to the air supply source 9 through the rotary joint 8.

The movable frame 4 supporting the second side plate 2b has side plates 2a,
Guide rod 10 fixed on the base parallel to the rotating shafts 3a and 3b of 2b
A screw rod 11 having a male screw on its outer circumference is screwed with a female screw of the movable frame 4 and is supported by a bearing of a support 12 having one end fixed to a base. The other end of the screw rod 11 is connected to a drive motor 13 fixed to the base.

[Action]

At the start of winding, the divided body portions 7a and 7b divided by the air cylinders 5 are moved to expand the diameter of the body portion 7, and the drive motor 13 rotates the screw rod 11 to move the movable frame 4 Move along the guide rod 10 to the second side plate
2b is separated from the body 7. Therefore, after the end portion of the elongated body is fed between the second side plate 2b and the body portion 7 from an insertion gate (not shown), the drive motor 13 is reversed to move the movable frame 4
By returning to the original position, the elongated body is sandwiched and fixed between the chuck groove formed in the body portion 7 and the second side plate 2b. Next, by rotating both rotary shafts 3a and 3b simultaneously in the same direction at the same speed by a driving device (not shown), the side plates 2a and 2b
The body 7 is rotated, and the elongated body is pulled out from the insertion gate and wound in a plurality of rows and a plurality of stages on the body 7 by the traverse device. However, the enlarged body 7 has the same outer diameter as a whole. Since the taper is not provided, it is possible to wind in line without disturbing the winding shape.

After the winding is completed, the screw frame 11 is rotated by the drive motor 13 to move the movable frame 4 again to separate the second side plate 2b from the body portion 7 with a long stroke. Therefore, after moving the divided body portions 7a, 7b by the air cylinders 5 to reduce the diameter of the body portion 7 as a whole, the wound long body is grasped by an automatic hand or the like and taken out from the body portion 7. .
Then, the air cylinders 5 are used to move the body portions 7a and 7b again to expand the diameter of the body portion 7 as a whole, and the drive motor 13 returns the movable frame 4 to the original position to move the second side plate 2b. The body portion 7 is brought into contact with the body portion 7, and the next winding operation is started.

The first rotating shaft 3a of the first side plate 2a is rotatably supported on the support column 1 and the first rotating shaft 3a is rotated by 90 ° so that the body portion 7 faces upward by a hydraulic cylinder or the like. By configuring so that it can rotate only by itself, the wound long body can be taken out upward.

Further, the side plates 2a and 2b are respectively wound by aligning them with the dividing portions of the body portion 7 and providing notches formed deeper than the body portion 7 from the peripheral edge toward the first rotating shaft 3a. Before the long body is taken out from the body portion 7, it is possible to bind the long body by passing a binding tape through the cutout portion using a normal binding machine.

[Effect of device]

ADVANTAGE OF THE INVENTION According to the winding drum device of the present invention, since the body is not tapered, the long body can be aligned and wound during winding, and the diameter of the body can be reduced as a whole while the body is cylindrical. By doing so, it is possible to easily take out the long body that is aligned and wound up without breaking the winding bundle.
