Abstract

PURPOSE: To prevent a wire material from being pulled back when the wire material is cut in an automatic traverse device in which the wire material is aligned and wound on a winding drum by holding the wire material at a closed position by a holding mechanism provided in a guide passage of an arm member after completion of winding of the wire material. CONSTITUTION: In winding a wire material 12, the wire material 12 is pulled along a guide passage prescribed by a guide roller 26, and pulleys 27, 28 composing a guide means by rotation of a winding drum 11 to be wound on the winding drum 11. Synchronously with rotation of the winding drum 11, a support base 19 moves to reciprocate on a track 18, so the wire material 12 is wound in an aligned condition. As an elevation part 24 of an arm member 23 reaches to a winding completion position to be applied to an upper stopper 25, the wire material 12 is cut more on the tip side of the arm member 23 than a holding mechanism 35, and prior to cutting of the wire material 12, the wire material 12 is held by actuation of the holding mechanism 35, thereby the wire material 12 can be prevented from being pulled back after it is cut.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic traverse apparatus suitable for aligning and winding a wire on a winding drum, and more particularly to an automatic traverse suitable for handling a wire having a relatively large weight such as a power cable. Regarding the device.

[0002]

2. Description of the Related Art An automatic traverse device used for winding an electric power cable around a winding drum includes a support base that reciprocates in the axial direction of the winding drum on the side of the winding drum, and on the support base. An arm member that extends from an elevating part supported so as to be able to ascend and descend to a winding drum toward a winding drum. A guide path for the wire is defined in the arm member by a guide means for guiding the wire from its rear end toward the tip near the winding drum. When the winding drum is driven and rotated around the rotation axis so as to wind the wire, the wire is sent to the winding drum along the guide path of the arm member in accordance with this rotation. With the rotation of the winding drum, the arm member provided with the guide path of the wire rod is sequentially displaced in the axial direction of the winding drum by an amount corresponding to the diameter of the wire rod, and the winding diameter of the wire rod is changed. According to the increase, the winding drum is displaced radially outward.
By the movement of the arm member, the wires are aligned and wound on the winding drum.

[0003]

By the way, in the above-mentioned conventional automatic traverse device, the guide means for defining the guide path of the arm member has a very low rotational resistance such as a pulley or a guide roller supported by the arm member. It is composed of a rotatable body. for that reason,
When the power cable is wound around the take-up drum, the power cable does not fall out of the guide path.However, for example, when the work of winding the power cable around one take-up drum is completed and it is replaced with an empty take-up drum. When the power cable is cut near the tip of the arm member, the power cable easily falls off the guide path due to its own weight.

Therefore, each time the drum after the winding operation is replaced with an empty winding drum, the tip of the power cable dropped from the guide path of the arm member is guided again around the pulley and the guide roller. It had to be repositioned along the route. Since the weight of the wire rod becomes larger as the power cable becomes thicker, it may be difficult for one worker to work with the large power cable for high voltage, resulting in a significant decrease in work efficiency. Therefore, it is an object of the present invention to provide an automatic traverse device which is excellent in work efficiency and does not need to be rearranged in the guide path every time the guided wire rod is cut.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an automatic traverse apparatus for winding a wire rod in a line around a winding drum which is driven and rotated about a rotation axis. It extends from the outside of the drum in the radial direction toward the winding drum, is displaced in the direction of the rotation axis of the winding drum as the winding drum rotates, and is wound in accordance with an increase in the winding diameter of the wire. Focusing on the arm member that is displaced radially outward of the drum, the guide path for the wire rod provided on this arm member operates between a closed position for holding the wire rod and an open position for releasing the wire rod. , When the winding of the wire on the winding drum is completed, it is moved to the closed position to hold the wire, and after the winding drum is replaced, the holding mechanism that feeds the wire toward the new winding drum at the closed position is installed. Established And it features.

[0006]

In the present invention, the holding mechanism provided in the guide path of the arm member is held at the open position when the wire rod is wound on the winding drum, so that the wire rod is prevented from being fed to the winding drum. It will not be done. Further, the clamping mechanism is operated to the closed position when the winding of the wire on the winding drum is completed, and clamps the wire at the closed position. Even if the wire rod is cut near the tip of the arm member to replace the winding drum with an empty winding drum in the state where the wire rod is clamped, the wire rod is in the closed position by the clamping mechanism.
Since the wire rod is reliably sandwiched, the wire rod is not easily pulled back by its own weight, and slipping of the wire rod from the guide path is reliably prevented. After replacement of the winding drum, the clamping mechanism in the closed position feeds the wire towards this new winding drum.

[0007]

The present invention will be described in detail below with reference to the illustrated embodiments. FIG. 1 is a front view schematically showing an automatic traverse device according to the present invention. Automatic traverse device 10
Is used for aligning and winding a wire 12 such as a power cable around the winding drum 11. The take-up drum 11 is arranged such that the flanges 14 formed at both ends of the take-up drum 13 serving as the rotation axis of the take-up drum 11 are placed on a pair of take-up rollers 16 in a pit 15. At least one of the take-up rollers 16 is driven to rotate,
As a result, the winding drum 11 is rotated in one direction about the longitudinal center axis of the winding drum 13, which is the axis of rotation, as indicated by arrow 17.

The automatic traverse device 10 comprises a pair of tracks 1 extending along a winding drum 13 on one side of a winding drum 11.
A support base 19 movably arranged on the support 8 and a support column 20 extending upward from the support base 19 are provided.

At the lower part of the support base 19, a reciprocating mechanism for the support base 19 is used, for example, a track 1 similar to the conventional one.
8 and the male screw member 21 and the male screw member 2
1 and the rotation of the male screw member 21 causes the female screw member 22 that moves integrally with the support 19 along the longitudinal axis of the female screw member 22 and the male screw member 21 to rotate positively around the longitudinal axis. An electric motor (not shown) for switching to the opposite direction is provided. The electric motor is controlled in rotation in synchronization with the rotation of the winding drum 11, as is well known in the art. This allows
The support 19 reciprocates on the track 18 in synchronization with the rotation of the winding drum 11 between the flanges 14 of the winding drum 11 in parallel with the winding drum 13.

The column 20 provided on the support 19 has
The arm member 23 is disposed so that the lifting portion 24 is slidably fitted therein. The column 20 is provided with a stopper 25 that restricts the movement of the elevating unit 24 between the center and the top. The arm member 23 extends toward the take-up drum 11 from an elevating part 24 located radially outward of the take-up drum 11. The arm member 23 is provided with guide means below the arm member, which defines a guide path for the wire 12 along its extension direction.

In the illustrated example, the guide means comprises a guide roller 26 and pulleys 27 and 28 which are sequentially arranged at intervals from the rear end side of the arm member 23 toward the front end side thereof. 2 and 3 are perspective views showing the guide roller 26 and the pulley 27, respectively. The guide roller 26 provided at the rear end portion of the arm member 23 is as shown in FIG.
As shown in FIG. 3, a rectangular frame body 29 with the both ends opened supported on the lower part of the arm member 23, and a pair of horizontal roller members 30 arranged in parallel in the frame body at a distance from each other, A pair of vertical roller members 31 is provided. Each of the roller members 30, 31 has a rotating shaft 32 rotatably supported by the frame body 29, and the wire 12 is passed between the pair of horizontal roller members 30 and between the pair of vertical roller members 31.

As shown in FIG. 3, the pulley 27 has a rotary shaft 33 rotatably supported by the arm member 23 via a bracket 34, and a V-shaped groove 35 'for receiving the wire 12. Are formed. The pulley 28 provided at the tip of the arm member 23 also has the same structure as the pulley 27. The wire rod 12 passing between the roller members 30 of the guide roller 26 and between the roller members 31 forms the pulley 2 that constitutes guide means together with the guide roller 26.
It is guided via 7 and 28 towards the winding drum 11.

Guide roller 2 which constitutes this guiding means
6, a pinching mechanism 35 according to the present invention is provided in the guide path defined by the pulleys 27 and 28. FIG. 4 is a front view showing the holding mechanism 35 shown in FIG. 1 with one of the brackets 36 removed.

In the illustrated example, a sandwiching mechanism 35 is provided between the pulleys 27 and 28, and the sandwiching mechanism 35 extends downward from both sides of the arm member 23 at a distance from each other. 4, one of which is omitted.), A pair of upper rollers 37 and a pair of lower rollers 38 that are arranged across both brackets 36, 36, and a pair of upper rollers 37. For example, an upper endless track 39 made of a rubber member, a lower endless track 40 made of a similar rubber member arranged around a pair of lower rollers 38, and a cylinder device 41 are provided.

The bracket 36 is an upper movable bracket portion 36 supported by the arm member 23 so as to be vertically movable.
A, and a lower fixed bracket portion 36 fixedly supported by the arm member 23 below the upper movable bracket portion 36A.
B. The pair of upper rollers 37 are supported by the upper movable bracket portion 36A, and the pair of lower rollers 38 are supported by the lower fixed bracket portion 36B. The cylinder device 41 is arranged on both endless tracks 3 around the rollers 37 and 38.
It is supported by the arm member 23 so as to operate the upper movable bracket portion 36A between 9 and 40 between a closed position for sandwiching the wire 12 passing therethrough and an open position for releasing the wire 12.

Therefore, the holding mechanism 35 releases the wire 12 passing between the two endless tracks 39 and 40 at the open position, so that the movement of the wire 12 to the winding drum 11 is not blocked. Further, the holding mechanism 35 holds the wire 12 by holding the wire 12 between the endless tracks 39 and 40 at the closed position. Further, the holding mechanism 35 is provided with a drive motor for allowing the wire rod 12 to be fed to the winding drum 11 at the closed position. This drive motor consists of a pair of upper rollers 3
7 and at least one of the rotating shafts 42 of the pair of lower rollers 38, and the holding mechanism 35 in the closed position delivers the wire 12 in its delivery direction by the operation of the drive motor.

In the automatic traverse device 10 according to the present invention, when the wire 12 is wound around the winding drum 11, the elevating part 24 contacts the lower stopper 25 as shown by the phantom line in FIG. Initialized to position. In this state, the wire 12 is guided by the winding drum 13 of the winding drum 11 through the guide roller 26, the pulley 27 and the holding mechanism 35, and further through the pulley 28 provided at the tip of the arm member 23. The tip portion is locked to the body 13. In this state, the pulley 28 is in contact with the winding drum 13.

When the winding roller 16 is driven with the tip of the wire 12 locked to the winding drum 13, the winding drum 11 is rotated in the direction of the arrow indicated by reference numeral 17.
By the rotation of the winding drum 11, the wire 12 is pulled out along the guide path defined by the guide roller 26 and the pulleys 27 and 28 that form the guiding means, and is wound around the winding drum 11. Further, since the holding mechanism 35 provided in the guide path is held at the open position by the cylinder device 41, the feeding of the wire 12 is not blocked, and the wire 12 smoothly moves to the winding drum 11. Be guided.

In synchronization with the rotation of the winding drum 11,
Since the support base 19 reciprocates between the flanges 14 of the winding drum 11 in parallel with the winding drum 13 on the track 18,
An arm member 23 supported by a column 20 on a support base 19
Are sequentially displaced toward one flange 14 along the winding cylinder 13 in accordance with the thickness of the wire 12. When reaching the one flange 14, the movement direction of the arm member 23 is reversed toward the other flange 14. At the same time,
In the arm member 23, the pulley 28 at the tip of the arm member 23 has the wire rod 12
Since it is mounted on the winding portion of the wire rod 12, the wire member 12 is pushed upward by the thickness of the wire rod 20, so that the arm member 23 sequentially increases the diameter of the winding drum 11 in accordance with the increase of the winding diameter of the wire rod 12. It is displaced outward in the direction, that is, upward in FIG. By this movement of the arm member 23, the winding drum 1
1, the wire rods 12 are aligned as well known in the art.
Is wound up.

As shown by the solid line in FIG. 1, when the raising / lowering portion 24 of the arm member 23 reaches the winding end position where it abuts against the upper stopper 25 and the winding is completed, the winding drum 11 is set to the empty one. In order to replace the wire member 12, the wire 12 is cut closer to the tip of the arm member 23 than the holding mechanism 35. Prior to the cutting of the wire 12, the clamping mechanism 35 is held in its closed position by the operation of the cylinder device 41 of the clamping mechanism 35. Therefore, when the wire rod 12 is cut, a tensile force due to its own weight acts on the wire rod 12 left on the guide path side of the arm member 23, but the holding mechanism 35 in the closed position operates between the endless tracks 39 and 40. The wire rod 12 is securely clamped by and is prevented from sliding. As a result, the wire rod 12 is reliably prevented from falling off the guide path due to its own weight.

A new empty take-up drum 11 is installed on the take-up roller 16 in a state where the wire 12 is prevented from falling off the guide path. After replacing the take-up drum 11, the rollers 37 or 3 of the holding mechanism 35 in the closed position are placed.
The drive motor incorporated in the rotary shaft 42 of No. 8 is operated, and the endless tracks 39 and 4 are driven by the operation of the drive motor.
Since 0 is circulated, the holding mechanism 35 in the closed position
The wire rod 12 is automatically paid out toward the winding drum 11. Therefore, it is not necessary to manually pull out the heavy wire 12 and the tip of the automatically drawn wire 12 can be easily locked to the winding drum 13. After the locking of the tip, the clamping mechanism 35 operates the winding drum 1 for the wire 12.
It is again held in the open position for winding around 1.

In this way, the guide route (26, 27, 2
8) The winding work can be started efficiently because the winding work can be started without rearranging the wire rod that has fallen out of the guide line again along this guide route and without manually feeding the wire rod. Can be done well.

The present invention is not limited to the above embodiments. An example in which a pair of endless tracks for sandwiching a wire rod is applied as the sandwiching mechanism has been described, but various sandwiching mechanisms capable of feeding out the wire rod can be applied. Further, the present invention can be applied to various relatively lightweight wire rods in addition to power cables having a large self-weight.

[0024]

In the automatic traverse device of the present invention described above, the pinching mechanism provided in the guide path of the arm member pinches the wire rod at the closed position when the winding of the wire rod on the winding drum is completed. Therefore, even if the wire rod is cut to replace the winding drum, the wire rod is not easily pulled back by its own weight, and slipping of the wire rod from the guide path is reliably prevented. Also, after the winding drum is replaced, the holding mechanism feeds the wire toward the new winding drum. Therefore, according to the present invention, it is not necessary to rearrange the vicinity of the tip end portion of the wire rod that has been cut each time the winding drum is replaced, in the guide path, and also without manually feeding the wire rod, Since the winding operation can be started, it is possible to efficiently perform the winding operation of the wire rod, and thereby the working efficiency can be significantly improved.
