Description

  The present invention relates to a cable feeding device that feeds a cable while holding the cable between a pair of gripping portions that rotate in opposite directions.

  Conventionally, as a cable delivery apparatus, there exists a thing of the structure described in patent document 1, for example. The cable delivery device described in Patent Document 1 has a pair of delivery rollers, and these pair of delivery rollers rotate in opposite directions to deliver a cable sandwiched therebetween. Each of the pair of delivery rollers is pivotally supported by a fixed pivot and a movable pivot that is movable with respect to the fixed pivot. A chain gear is fixed to each pivot, and these chain gears, idler gears to guide gears, and the like. , The chain is hung around. When the chain gear fixed to the fixed pivot is rotated, the chain transmits the rotation, the chain gear fixed to the movable pivot rotates, and the pair of delivery rollers rotate together.

  In order to correspond to the diameter of the cable to be delivered, the movable pivot can be moved closer to or away from the fixed pivot. The chain gear may sag due to secular change, but this is absorbed by the idler gear and the guide gear.

  However, in the cable delivery device of Patent Document 1, the chain gear is wound through many gears due to the presence of the idler gear and the guide gear. For this reason, the entire length of the chain is long, and on the pulling side of the chain, it is easy to apply tension to the chain, and torque loss related to transmission is likely to occur. On the other hand, on the slack side of the chain, the chain is easy to sag, and when the chain extends over time, the meshing with the gear is disengaged and it is easy to cause idle rotation. For this reason, the tension of the chain must be frequently adjusted, that is, the maintenance frequency is high.

  The present applicant has already developed the cable delivery device of Patent Document 2 in order to improve the drawbacks of the cable delivery device of Patent Literature 1. Specifically, the cable delivery device of Patent Document 2 is disposed to face each other, and supports a pair of gripping portions for feeding the cable between them, one of the pair of gripping portions, and at a predetermined position. A fixed rotation shaft provided rotatably, and a rotation rotation provided to support the other of the pair of gripping portions and to be rotatable, and to be movable in a direction approaching and separating from one gripping portion. An axis, a driving means for rotating the fixed-side rotating shaft, and a transmission mechanism for transmitting the rotation of the fixed-side rotating shaft to the moving-side rotating shaft. The transmitting mechanism includes the fixed-side rotating shaft and the moving-side rotating shaft. A transmission gear that is fixed to one of the teeth and has teeth around it, an intermediate gear that has teeth around and meshes with the transmission gear, and one of the fixed rotation shaft and the movable rotation shaft and the intermediate gear Between the rotation axis of A first link member, an intermediate transmission wheel fixed to the rotation shaft of the intermediate gear, a transmission wheel fixed to one of the fixed side rotation shaft and the movement side rotation shaft, and the intermediate transmission wheel and the transmission wheel It is characterized by having a transmission belt stretched between them, and a second link member for connecting the rotation shaft of the intermediate gear and any one of the fixed-side rotation shaft and the movement-side rotation shaft.

  In the cable delivery device of Patent Document 2 configured as described above, when the fixed-side rotation shaft is rotated by the driving means, one of the gripping portions fixed to the fixed-side rotation shaft rotates. The rotation of the fixed side rotation shaft is transmitted to the movement side rotation shaft by the transmission mechanism, and the other of the gripping portions rotates. In the transmission mechanism, the intermediate gear is either the fixed rotation shaft or the movable rotation shaft by the transmission gear fixed to one of the fixed rotation shaft and the movement rotation shaft and the intermediate gear meshing with the transmission gear. It rotates in the opposite direction of either rotation. Then, the rotation of the intermediate gear is transmitted to one of the fixed rotation shaft and the movable rotation shaft by the intermediate transmission wheel, the transmission wheel, and the transmission belt.

  Further, the moving side rotating shaft can be moved relative to the fixed side rotating shaft in order to adjust the distance between the pair of gripping portions. At this time, the rotating shaft of the intermediate gear of the transmission mechanism is rotatably connected to one of the moving-side rotating shaft and the fixed-side rotating shaft by the first link member. Here, since the distance between the intermediate gear and the transmission gear is maintained constant, the intermediate gear moves around the transmission gear while maintaining the meshing state with the transmission gear. On the other hand, the rotation shaft of the intermediate gear of the transmission mechanism is rotatably connected to either the moving-side rotation shaft or the fixed-side rotation shaft by the second link member. As a result, the intermediate transmission wheel fixed to the rotation shaft of the intermediate gear is arcuate around the other of the moving side rotation shaft and the fixed side rotation shaft while maintaining a constant distance from the transmission wheel. Will be moved to.

  In the cable delivery device of Patent Document 2 configured as described above, since the transmission mechanism has a transmission gear and an intermediate gear having teeth around, a part of the transmission mechanism can be a mechanism by meshing of the gears. . Therefore, it is not necessary to use a long chain wound around many conventional gears, and the problem of chain slack as in the conventional case is reduced. This facilitates maintenance of the transmission mechanism.

  In addition, one of the fixed side rotating shaft and the moving side rotating shaft and the rotating shaft of the intermediate gear are rotatably connected by the first link member, and the rotating shaft of the intermediate gear, the fixed side rotating shaft, and the moving side rotating shaft are connected. Since either one of them is rotatably connected by the second link member, the distance between one of the fixed side rotation shaft and the movement side rotation shaft and the rotation shaft of the intermediate gear, and the intermediate gear It is possible to keep the distance between the rotary shaft and the other of the fixed side rotary shaft and the moving side rotary shaft constant. Therefore, even when the moving side rotating shaft is moved relative to the fixed side rotating shaft, the meshing between the transmission gear and the intermediate gear and the engagement relationship between the intermediate transmission wheel and the transmission wheel and the transmission belt are maintained. Rotational motion is transmitted reliably.

Japanese Patent No. 2860786 JP-A-2006-10197

  FIG. 10 shows a cross-sectional view of the cable delivery device of Patent Document 2 (corresponding to FIG. 2 of Patent Document 2). As shown in FIG. 10, in the cable delivery device of Patent Document 2, the intermediate transmission wheel 150 is fixed to the rotating shaft 148 of the intermediate gear 146. It is not easy to reduce the height.

  On the other hand, in recent years, there has been a demand for a cable feeding device that can be installed and operated in a very low height space.

  The present invention has been created based on the above findings. An object of the present invention is to provide a cable delivery device that can be installed and operated even in a space with a very low height.

  The present invention provides a pair of gripping portions disposed opposite to each other, a first rotating shaft that supports one of the pair of gripping portions and is rotatably provided, and supports the other of the pair of gripping portions.

  In the cable delivery device of the present invention configured as described above, when the first rotation shaft is rotationally driven by the drive mechanism, one of the gripping portions fixed to the first rotation shaft rotates. The rotation of the first rotation shaft is transmitted to the second rotation shaft by the transmission mechanism, and the other gripping portion rotates. More specifically, in the transmission mechanism, the first intermediate gear rotates in the direction opposite to the rotation of the first rotation shaft by meshing between the first transmission gear fixed to the first rotation shaft and the first intermediate gear. The second intermediate gear rotates in the rotation direction of the first rotation shaft by meshing the first intermediate gear and the second intermediate gear. Furthermore, the second transmission gear rotates in the direction opposite to the rotation of the first rotation shaft by the meshing of the second intermediate gear and the second transmission gear.

At this time, the central shaft that supports the first intermediate gear and the central shaft that supports the second intermediate gear are rotatably connected by the first link member. Therefore, the second intermediate gear moves around the first intermediate gear while maintaining the meshing state with the first intermediate gear. On the other hand, the central shaft that supports the second intermediate gear is also rotatably connected to the second rotation shaft by the second link member. As a result, the second intermediate gear moves in an arc shape with respect to the second transmission gear while maintaining a constant distance from the second transmission gear.

  In addition, a central shaft that supports the first intermediate gear and a central shaft that supports the second intermediate gear are rotatably connected by the first link member, and the central shaft that supports the second intermediate gear and the second rotation shaft Are pivotally connected by the second link member, so that the distance between the central shaft supporting the first intermediate gear and the central shaft supporting the second intermediate gear and the second intermediate gear are supported. The distance between the central axis and the second rotation axis can be kept constant. Therefore, even when the first rotating shaft is moved relative to the second rotating shaft, the meshing between the first intermediate gear and the second intermediate gear and the meshing between the second intermediate gear and the second transmission gear are performed. It is maintained and rotational motion is reliably transmitted.

  In the present invention, the rotation speed ratio of the first transmission gear, the first intermediate gear, the second intermediate gear, and the second transmission gear is 1: n: n: 1, where n is a natural number of 1 or more. Particularly preferably, the rotation speed ratio of the first transmission gear, the first intermediate gear, the second intermediate gear, and the second transmission gear is 1: 1: 1: 1. In such a case, the structure of the transmission mechanism Becomes easier. Furthermore, in terms of manufacturing cost, it is preferable that the first transmission gear, the first intermediate gear, the second intermediate gear, and the second transmission gear are at least partially constituted by a common gear member.

  In the present invention, the drive mechanism includes a drive gear having teeth around and a drive side intermediate gear having teeth around and meshing with the drive gear and the first transmission gear. Is preferred. In this case, the rotational speed ratio of the drive-side intermediate gear, the first transmission gear, the first intermediate gear, the second intermediate gear, and the second transmission gear is m: 1: n, where n and m are natural numbers of 1 or more. : N: 1, more preferably 1: 1: 1: 1: 1.

A transmission gear, a first intermediate gear having teeth around and meshing with the first transmission gear, a second intermediate gear having teeth around and meshing with the first intermediate gear and the second transmission gear; Therefore, the entire transmission mechanism can be a mechanism by meshing gears. Therefore, it is not necessary to use a chain as in the prior art, and the problem of chain sag is eliminated. This facilitates maintenance of the transmission mechanism.

  Since a conventional transmission mechanism using a chain is unnecessary, the transmission mechanism of the cable feeding device of the present invention can be designed and manufactured at a very low height. Thereby, the cable delivery device of the present invention can be installed and operated even in a space with a very low height.

The shaft 21 and one gripping part 11 rotate.

  The rotation of the first rotation shaft 21 is transmitted to the second rotation shaft 22 by the transmission mechanism, and the other gripping portion 12 rotates. More specifically, in the transmission mechanism, the first intermediate gear 34 reverses the rotation of the first rotary shaft 21 by meshing the first transmission gear 33 fixed to the first rotary shaft 21 with the first intermediate gear 34. Rotate in the direction. The second intermediate gear 35 rotates in the rotation direction of the first rotation shaft 21 by the meshing of the first intermediate gear 34 and the second intermediate gear 35. Further, due to the engagement of the second intermediate gear 35 and the second transmission gear 36, the second transmission gear 36 fixed to the second rotation shaft 22 rotates in the direction opposite to the rotation of the first rotation shaft 21.

Since the shaft 35c and the second rotating shaft 22 are rotatably connected by the second link member 52, the central shaft 34c for supporting the first intermediate gear 34 and the central shaft 35c for supporting the second intermediate gear 35 are supported. And the distance between the center shaft 35c supporting the second intermediate gear 35 and the second rotating shaft 22 can be kept constant. Therefore, even when the first rotary shaft 21 is moved relative to the second rotary shaft 22, the meshing between the first intermediate gear 34 and the second intermediate gear 35, and the second intermediate gear 35 and the second transmission gear. The meshing with 36 is maintained and the rotational motion is reliably transmitted.
