Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a wide band-shaped sheet is divided into a plurality of narrow width sheets by a slitter and wound around individual cylindrical cores mounted on the outer circumference of a winding shaft. The present invention relates to a winding restart preparation device in a sheet split winding device that takes out each winding roll from a winding shaft that forms a roll and is cantilevered to the free end side.

[0002]

2. Description of the Related Art Conventionally, a winding resumption preparing device in a sheet split winding device as described above is rotatable about a vertical axis provided on a movable base which can move forward and backward in the longitudinal direction of a winding shaft. As such a movable support, there is one in which a receiving shaft of a winding roll and a core preparation shaft are cantilevered horizontally at a predetermined rotation angle in the radial direction at the same height as the winding shaft. In this device,
In preparation for the next winding operation, a new winding core is installed on the outer circumference of the winding core preparation shaft in the same arrangement as on the winding shaft, and when the winding roll is wound up, the movable support is rotated to receive it. The shaft is opposed to the winding shaft, and the movable table is moved forward to connect the winding shaft and the receiving shaft. Then, the take-up roll is pushed out from the take-up shaft in the cantilevered support state, and the take-up roll is supported by the receiving shaft while penetrating the winding core. After that, the movable base is moved backward to rotate the movable support, the core preparation shaft is replaced with the receiving shaft, and the movable base is advanced again to connect the winding shaft and the core preparation shaft. Then, the winding core is pushed out from the winding core preparation shaft and mounted on the winding shaft (see, for example, JP-A-3-267248). According to this apparatus, the take-up roll is received by the receiving shaft while passing through the winding core, so that the outer circumference of the take-up roll is not damaged.

[0003]

Generally, the inner diameter of the winding core is standardized in order to obtain compatibility of the winding core holder of the winding roll in various processing and processing steps of the strip-shaped sheet.
On the other hand, in the above-described sheet split winding device, since the winding core for each narrow sheet is supported by the common winding shaft, the length of the winding shaft is increased according to the width of the strip-shaped sheet supplied to the slitter. There is a need to. Therefore, when the width of the strip-shaped sheet supplied to the slitter is wide, the winding shaft applied to the slitter has the same long length as that of the case where the width of the strip-shaped sheet is narrow, and only the length thereof is long. When the take-up shaft is lengthened, the load applied to the take-up shaft increases correspondingly. However, the mechanical strength of the winding shaft cannot be increased. Therefore, as the width of the divided strip-shaped sheet becomes wider, the take-up shaft that is in a cantilevered support state when the take-up roll is pushed out is more likely to bend due to the weight of the take-up roll, and its free end becomes the cantilevered support end. Compared to lowering.

However, the following problems occur in the winding restart preparation device in the conventional sheet dividing winding device. That is, at the time of delivery of the winding roll, the receiving shaft or the core preparation shaft simply faces the tip of the winding shaft,
The take-up shaft remains cantilevered. In a sheet dividing device applied to a wide strip-shaped sheet, the weight of the winding roll on the winding shaft becomes large, and when the winding roll is pushed out from the winding shaft to the receiving shaft, the winding shaft largely bends. Therefore, there is a difference in height between the tip of the receiving shaft and the tip of the winding shaft. Since the gap between the inner circumference of the winding core and the outer circumference of the winding shaft is very small, when the winding roll is pushed out from the winding shaft to the receiving shaft, the end surface of the winding core of the winding roll hits the end surface of the receiving shaft. The take-up roll does not move to the receiving shaft. Further, when the core is soft, such as a paper tube, the end surface or the inner peripheral surface of the winding core of the take-up roll is damaged and the product value is impaired. Since the weight applied to the winding shaft varies depending on the winding amount of the narrow sheet, it is not possible to adjust the height of the receiving shaft in advance in consideration of the amount of bending of the winding shaft. Further, when the core is attached, a misalignment between the core preparation shaft and the winding shaft may occur due to a positioning error of the carriage. In that case, the winding core may be caught at the connecting portion between the winding preparation shaft and the winding shaft and may not move smoothly onto the winding shaft, or the winding core may be damaged.

Therefore, according to the present invention, it is possible to smoothly take out the take-up roll and mount a new core, and to reduce the take-up time of the wind-up roll and the core mounting time. An object is to provide a winding restart preparation device in a winding device.

[0006]

According to the present invention, a center hole having an inclined inner peripheral surface is provided at the tip of the winding shaft, and the receiving shaft centering rod is concentric with the receiving shaft and the receiving shaft centering rod. So that the tip end of the core preparation shaft is fitted in the center hole, and the core preparation shaft alignment rod is concentric with the core receiving shaft and the tip end of the core preparation shaft alignment rod is fitted in the center hole. To be installed.

Since the center hole has the inclined inner peripheral surface, the inlet of the center hole can be made sufficiently larger than the tip end portion of the receiving shaft alignment rod fitted in the center hole. When the take-up shaft is supported in a cantilevered state to push the take-up roll from the take-up shaft, the take-up shaft bends due to the weight of the take-up roll, causing the tip of the product unloading side to drop, and Even if the tip of the receiving shaft centering rod is deviated from the center of the receiving shaft, the large entrance of the center hole can receive the tip of the receiving shaft aligning rod. When the tip of the receiving shaft centering rod is pushed into the center hole, the tip of the receiving shaft centering rod is pushed toward the center of the winding shaft by the inclined inner peripheral surface as the tip of the receiving shaft centering rod goes further into the center hole. Fitted in the hole. As a result, the receiving shaft and the winding shaft are aligned and concentric with each other, and the winding shaft in the cantilevered state is supported by the receiving shaft on the free end side. Even if the tip of the winding shaft and the tip of the core preparation shaft disagree with each other when the core is attached, the center hole and the core preparation shaft centering rod work similarly to the receiving shaft. The core preparation shaft and the winding shaft are aligned and are concentric.
