Description

[Detailed Description of Device] a. The purpose of the invention (industrial field of application) The present invention relates to a winding device for aligning and winding cables and the like,
Further, the present invention relates to a guide device for holding a cable or the like and guiding it onto the winding drum in this winding device.

(Prior Art) When winding a cable such as an electric wire or an optical fiber on a winding drum, it is desirable to perform winding in order to prevent bending or bending or to wind efficiently. For this reason, for example, a cable guide device is arranged in front of the winding drum (that is, at a position apart from the front side where the cable is wound from the winding drum), and the cable is held by the guide device. The guide device is moved in parallel with the rotation axis of the winding drum at a speed corresponding to the rotation of the winding drum,
Frequently, the cable is guided to the proper position for aligned winding on the winding drum. However, when the guide device is arranged at a position distant from the winding drum as described above, the cable may be loosened due to its own weight between the guide device and the winding drum. If there is such slack, the cable being wound may largely swing and deviate from an appropriate winding position on the winding drum to make reliable aligned winding difficult. Therefore, the present applicant sandwiched the cable with a plurality of rollers, and further urged one roller so that its rotation surface pressed the cable against the rotation surface of the other roller, so that the cable was always stretched appropriately. We have proposed a guide device that can be maintained in a state.

Further, in such a guide device, in order to securely hold the cable, the biased roller (hereinafter,
A biasing roller) and its corresponding roller (hereinafter,
A pair of rollers orthogonal to the force receiving roller) is arranged on both sides of the cable, and the four-sided roller composed of two pairs of rollers arranged in a cross beam is used to surround and hold the cable. Sometimes.

When a cable is attached to the guide device having such a four-sided roller, a relatively large metal fitting is often attached to the tip of the cable.
Since the tip cannot be passed between the surface rollers, one of the rollers other than the urging roller and the urging roller is opened (hereinafter, this openable roller is referred to as an openable roller), and the opening portion thereof is opened. Cables are often fitted (from the side of the guide device).

(Problems to be solved by the invention) However, as described above, the biasing roller approaches the biasing roller due to the biasing force before the cable is attached.
Therefore, in this state, the diameter of the cable to be attached may be larger than the distance. In such a case, in order to mount the cable, the opening / closing roller must be opened and the biasing roller must be pushed back against the biasing force to widen the distance between the biasing roller and the receiving roller to be equal to or larger than the diameter of the cable. However, there is a problem that it takes time.

In view of the above problems, it is an object of the present invention to provide a cable guide device in which when the opening / closing roller is opened, the distance between the biasing roller and the biasing roller automatically increases.

B. Configuration of the Invention (Means for Solving the Problems) In order to achieve the above-mentioned object, in a cable guide device of the present invention, a pair of first and second rollers, which are two rollers parallel to each other, are made orthogonal to each other. One roller (opening and closing roller) that is arranged in a cross beam and constitutes the first roller pair,
Around the one axial end of the open / close roller, the open / close roller is configured to be swingable between a closed position that encloses a space for holding a cable and an open position that opens this space at a place surrounded by the open / close roller. , One roller (biasing roller) forming the second roller pair and the other roller (biasing roller)
When the opening / closing roller is oscillated in the direction from the closed position to the open position, the urging means for urging the urging means urges the urging roller in conjunction with the movement of the opening / closing roller. And a moving unit that moves in a direction away from the receiving roller against the force.

(Operation) In such a guide device, when the cable is attached, the opening / closing roller is opened to open the end of the space for pinching the cable surrounded by the four-sided roller, and the cam or the like interlocked with the opening operation is performed. By the action of, the urging roller moves against the urging force, and the distance between the urging roller and the urging roller is expanded so as to be larger than the diameter of the cable. Therefore, the cable can be easily attached.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

First, a winding device equipped with a four-sided roller type cable guide device according to the present invention will be described with reference to FIG. The winding device 30 includes the cable guide device 1, a traverse device 31, a winding drum 32, and a drum drive motor 33.

Cable guide device 1 arranged in front of the winding drum 32
, Two pairs of rollers R (7, 13, 23, 28 shown in FIG. 1) are arranged in a cross beam orthogonal to each other, and the cable C moves toward the winding drum 32 at the center thereof.

The traverse device 31 includes a traverse table 34 and a traverse shaft 3
5, it is composed of a traverse motor 36 and a guide rail 37. A spiral rail groove is provided on the surface of the traverse shaft 35 so as to reciprocate between both ends. In addition,
A rotating shaft of a traverse motor 36 is connected to the right end of the traverse shaft 35. Further, the guide rail 37 is arranged parallel to the traverse shaft 35. This guide rail 37
A traverse base 34 is mounted on the upper side so as to be movable left and right, and a pawl (not shown) provided at a lower portion of the traverse base 34 is engaged with a rail groove of the traverse shaft 35.
Further, the cable guide device 1 is mounted on the traverse table 34.

The rotating shaft of the winding drum 32 is arranged in parallel with the traverse shaft 35, and is connected to the rotating shaft of the drive motor 33. In addition,
The drive motor 33 and the traverse motor 36 are connected via a signal line 33a so that they rotate in synchronization with each other.

In the winding device 30 having the above configuration, when the drive motor 33 is rotated and the winding drum 32 is rotated, the winding of the cable C is started. On the other hand, receiving the synchronization signal from the drive motor 33, the traverse motor 36 rotates and the traverse shaft 35 rotates. According to the rotation of the traverse shaft 35, that is, the rotation of the rail groove, the claw of the traverse base 34 is pushed to the left or right, and the traverse base 34 moves along the guide rail 37. In this way, the guide device 1 moves in order to wind the cables C in line according to the rotation of the winding drum 32.

Next, the configuration of the cable guide device 1 will be described with reference to FIG. The guide device 1 includes a main body 2, a cable attaching / detaching mechanism 3, and a roller pressing mechanism 4.

A mounting hole 5 for attaching to the traverse base 34 is formed in the upper portion of the main body 2. A cable attaching / detaching mechanism 3 is attached to the center of the main body 2. Further, an ear portion 6 is formed below the attachment position of the cable attaching / detaching mechanism 3 so as to project to the side of the main body 2.

The cable attaching / detaching mechanism 3 includes an opening / closing roller 7, a drive cam 8, a driven cam 9, and a push-up plate 10. The drive cam 8, the driven cam 9 and the push-up plate 10 constitute "moving means" in the claims. The open / close roller 7 has a rotary shaft arranged vertically with respect to the main body 2. The upper part of the rotary shaft is attached to the fulcrum shaft 11, and the lower part is detachably held by the main body 2, as shown in FIG. , Is a cross-sectional view taken along the line II-II) and can be opened and closed about the fulcrum shaft 11 (however, when the guide device 1 is used, it is attached to the main body 2 by a stopper (not shown)). Fixed). A drive cam 8 is attached to the fulcrum shaft 11. Further, a driven shaft 12 is arranged above the fulcrum shaft 11 in parallel therewith. A driven cam 9 is mounted on the driven shaft 12 at a position corresponding to the drive cam 8 and a push-up plate is provided near the center.
10 is fixed.

A fixed roller 13 is rotatably attached to the lower portion of the main body 2 so as to sandwich the cable C with the open / close roller 7. The open / close roller 7 and the fixed roller 13 form a “first roller pair” in the claims.

Next, the configuration of the roller pressing mechanism 4 will be described. The roller pressing mechanism 4 is composed of two box members 21, a connecting rod 22, an urging roller 23 and two springs (urging means) 24. Both box members 21 have a connecting rod at the top.
Both ends of a biasing roller 23 are rotatably attached to the lower portions of both box members 21, respectively. Inside the box member 21, near the upper edge,
The upper end of 24 is attached via an adjusting screw 25. With this adjusting screw 25, the length of the spring 24, that is, the urging force can be adjusted.

The roller push-down mechanism 4 having such a structure is provided for both box members.
21 are attached so as to sandwich the main body 2. The main body 2
Above the mounting position of the driven shaft 12 of is a through hole 26 for the connecting rod.
Is provided, and the connecting rod 22 is passed through the through hole 26. The through hole 26 is a vertically long hole so that the connecting rod 22 can move vertically with respect to the main body 2. Further, below the ears 6 of the main body 2, an opening 27 is provided on the mounting side of the opening / closing roller 7, and a roller through hole 28 is provided on the opposite side. The biasing roller described above is provided in the opening 27 and the through hole 28.
23 is passed. The opening 27 is connected to a U-shaped notch opening 2a formed on the back surface of the main body 2, and after opening the opening / closing roller 7, the cable C is connected to the four rollers from the side of the main body 2 ( 7, 13, 23, 29) and is provided for insertion into a space for holding a cable, which is to be surrounded by. The through hole 28 is vertically long so that the rotating shaft of the biasing roller 23 can move vertically with respect to the main body 2.

The ear portion 6 of the main body 2 projects from the lower portion inside the box member 21, and the lower end portion of the spring 24 is attached to the ear portion 6. In this way, the roller pressing mechanism 4 mounted on the main body 2 has the spring 24
The urging force of the contraction side of the body always pushes the body 2 downward.

At the lower end of the main body 2, a force receiving roller 29 is provided.
It is attached rotatably so as to sandwich 23 and the cable C. The urging roller 23 and the urging roller 29 form a "second roller pair" in the claims.

Next, the operation of the guide device 1 will be described.

First, when attaching the cable to the guide device 1, the second
As shown by the chain line in the figure, the opening / closing roller 7 is swung to the open position. At this time, the drive cam 8 rotates integrally with the fulcrum shaft 11. The driven cam 9 is pushed by the drive cam 8 to rotate, and the driven shaft 12 also rotates to raise the tip of the push-up plate 10. Therefore, the push-up plate 10 pushes up the connecting rod 22 of the roller pushing mechanism 4 against the biasing force of the spring 24. In this way, the entire roller pressing mechanism 4 is lifted up with respect to the main body 2 in conjunction with the opening operation of the opening / closing roller 7, and as a result, the distance between the urging roller 23 and the urging roller 29 (cable holding space) is increased. , If the distance is made larger than the diameter of the cable C,
The cable C can be easily attached through the opening 27.

After mounting the cable C in this way, the second
As shown by the solid line in the figure, when the open / close roller 7 is swung to the closed position, the roller pressing mechanism 4 is pushed down by the urging force of the spring 24, and the cable C is connected to the second fixed roller 29 by the rotating surface of the urging roller 23. It is pressed against the rotating surface of and deforms slightly. The pressing force can be adjusted by the adjusting screw 25 as described above. Thus, the biasing roller 23 and the receiving roller
When the cable C sandwiched between 29 and 29 is wound up by the winding drum 32, the deformation of the cable C in the sandwiched portion causes resistance to running. Due to this resistance, the cable C between the guide device 1 and the winding drum 32 is
It does not slacken due to its own weight, and is always stretched straight. Therefore, the swinging of the cable C during winding and the deviation from the winding position are suppressed, and the cable C is wound at the proper position for the aligned winding on the winding drum 32.

C. Effect of the Invention As described above, with the use of the cable guide device, when the cable is attached, when the openable roller is operated to open, the corresponding roller is linked by the biasing force before the cable is attached. Since the adjacent rollers are moved so as to be pushed back against the urging force, the distance between the rollers (space for holding the cable) can be made larger than the diameter of the cable. Therefore, the cable can be easily attached only by the operation of opening the openable / closable roller, and the working efficiency can be improved.
