Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape rewinding device that supplies tape to a tape winding device, and more specifically relates to a mounting shaft of the tape rewinding device.

In recent years, with the spread of center-type tape winding devices that are equipped with multiple tape reels and that alternately wind tape from the outside and simultaneously wind the tape around a wire,
There is a demand for speeding up the installation of tape in a tape rewinding device that supplies tape to this tape winding device from the outside.

In conventional tape rewinding devices, the tape is installed by removing the nut on the mounting shaft, transporting the full tape using a crane, etc., and finely aligning the outer circumference of the mounting shaft and the inner circumference of the full tape. This was done by pushing a full tape onto the mounting shaft, inserting a washer into the shaft, and then tightening the nut.

However, this method requires time to attach and detach the nut, and in some cases, the loading operation on the tape rewinding device is not completed while one reel of the tape winding device is being wound, and the tape There is a drawback that when the winding device is stopped, the tape replacement and connection work cannot be performed immediately. Another drawback was that the above work could not be carried out by one person.

This invention was created in view of the above drawbacks,
To provide a mounting shaft for a tape rewinding device that allows one person to load a tape into the tape rewinding device in a short time.

The above object includes a bearing 2, a shaft 1 which is supported by the bearing 2 and has a truncated conical protrusion a and a radially extending flange b, and a washer 8 fixed to one end of the shaft 1. a rod 7 that is slidable in a through hole c provided at the center; and a cylindrical elastic member 11 that is placed on the trapezoidal circumference of the protrusion a of the shaft 1 and is pressed against the inner circumference of the tape. This can be achieved by constructing the mounting shaft of the tape rewinding device from a plurality of claw members 10 supported by the trapezoidal circumferential surface of the protrusion a, the cylindrical elastic member 11, and the inner surface of the washer 8. can.

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a diagram showing a mounting shaft of a tape rewinding device according to the present invention, and a shaft 1 and a bearing 2 are shown. The shaft 1 is driven by a motor (not shown) via pulleys 3, 4, 5 and a belt connecting these pulleys. Further, a powder brake 6 is connected to the pulley 4, and appropriate tension is applied to the tape supplied to the tape winding device. One end of the shaft 1 is provided with a truncated conical protrusion a and a radially extending collar b. The shaft 1 is further provided with a through hole c along the axis, and a rod 7 having the same diameter as the hole is slidably inserted into the through hole. A washer 8 having an outer diameter slightly smaller than the inner diameter of the full tape (core material) to be attached is fixed to one end of the rod 7 and is tightened with a nut 9. Furthermore, on the truncated conical outer surface of the protrusion a of the shaft 1, there is a wedge-shaped claw member 10 which is divided into a plurality of pieces and whose inner surface has a shape corresponding to this outer surface and whose outer peripheral surface is parallel to the axis. is provided. Furthermore, an elastic member 11 is inserted onto the outer peripheral surface of the claw member 10, the outer diameter of which is equal to that of the washer 8, and the axial length of which is slightly longer than the tape width. This elastic member is a cylindrical member made of, for example, urethane rubber, and as will be described later, supports the claw member when the tape is removed and firmly supports the tape when it is attached. Furthermore, the side surface of the tape is abutted and supported by the flange b of the shaft 1 or a guide plate 18 fixed to the flange.

On the other hand, the other end of the rod 7 is a bearing 1 such as a thrust bearing.
2, one end is fixed as a fulcrum 13, and the other end is fixed to a shifter lever 15 connected to a cylinder of a fluid pressure means 14.

Furthermore, the mounting shaft of the present invention is as shown in FIG.
It is preferable to provide a rib 16 for guiding the claw member 10 on the outer peripheral surface of the protrusion a. Furthermore, it is preferable to provide a plurality of slits 17 on the outer surface of the elastic member 11.

It is also possible to provide a concave slit in the radial direction on the inner surface of the washer, and to fix the pawl member to a member that is slidable within this slit. In this case, the claw member is biased toward the axial center by a spring or the like, and when the tape core material is removed, the elastic member can easily contract (return to its original shape), so that the removal operation can be performed quickly.

The configuration of the present invention has been described above, and now the tape mounting operation using this configuration will be explained.

Transport the tape to be mounted near the mounting shaft using a crane, etc., and when the tape approaches the mounting shaft, make sure that the inner diameter of the tape and the outer diameter of the washer 8 match, for example, the upper end (the inner diameter of the tape is the outer diameter of the washer 8). Then, the tape is conveyed until the side surface of the tape abuts the guide plate 18 fixed to the collar b of the shaft 1. When the tape reaches this position, the operator releases the operating panel of the crane and presses the activation button of the hydraulic means 14 provided within reach from that position. Then,
As the cylinder of the fluid pressure means 14 extends in the right-hand direction in FIG. 1, the shifter lever 15 pivotally supported by the cylinder rotates counterclockwise about the fulcrum 13. Then, the rod 7 fixed in the middle of the shift lever 15 is slid to the right in the figure. Then, the claw member regulated by the washer 8 fixed to one end of the rod 7 slides to the right in the axial direction along the outer circumferential surface of the protrusion a and also slides outward in the radial direction, so that the outer circumference of the claw member 10 The elastic member inserted into the surface is regulated and compressed by (the core material of) the tape's inner periphery. Therefore, the tape can be firmly attached and fixed to the shaft 1.

In addition, when the tape core material is removed, the fluid pressure means 14
All you have to do is operate it in the opposite direction.

As mentioned above, one person can attach and detach the tape, which conventionally had to be done by multiple people, and the complicated work of attaching and tightening washers and nuts can be omitted. can be done efficiently.
