[0001]

The present invention relates to a belt-like sheet to multiple conditions
The slitter to be split and the bearing at the winding position during winding
Ri is supported at both ends, two and winding shaft arranged in parallel, the winding
After the take-up roll is completed, pull out the reel from the take-up position,
A reel removal mechanism that can return to the take-up position,
A take-up roll receiver provided below each of the above-mentioned winding shafts so as to be movable up and down.
Together and a winding device, a plurality condition by the slitter
The present invention relates to a slitter rewinder for a wide band-shaped sheet, which alternately divides the divided band-shaped sheets into the above-mentioned two winding shafts and winds them around respective winding cores fitted on the outer periphery of the winding shaft.

[0002]

2. Description of the Related Art In a slitter rewinder of this type, the outer diameter of the winding shaft is limited by the inner diameter of the winding core, so that the mechanical strength of the winding shaft cannot be increased even if the length of the winding shaft is increased. Therefore, if the length of the winding shaft is increased in order to increase the width of the strip-shaped sheet that can be processed, the winding shaft is bent by the weight of the winding roll, so that a high-quality winding roll cannot be obtained. In addition, the winding shaft may be damaged, which is dangerous. Therefore, the conventional slitter rewinder of the above-mentioned type is applied only to the division winding process of a narrow band-shaped sheet so as not to cause such a problem. For example, when a 3-inch paper tube is fitted onto a friction winding shaft as disclosed in Japanese Utility Model Publication No.
Usually, the length of the winding shaft is 2 meters or less. And a wide band-like sheet exceeding the specification, for example,
A large-sized slitter rewinder that supports and winds the winding core of each of the divided belt-shaped sheets with a pair of support arms is supplied to a slitter rewinder of the type described above in advance as a winding roll for a narrow band-shaped sheet.

[0003]

However, recently, the types of the strip-shaped sheets and the dimensions at the time of manufacture and shipment thereof have been diversified, and the strip-shaped sheets having a width slightly larger than the strip-shaped sheet width specification of the slitter rewinder of the above-mentioned type. It is also necessary to make the sheet into a narrow strip-shaped sheet and wind it up. However, even in such a case, it is conventionally inefficient because in the related art, a large-sized slitter rewinder as described above has to be once divided into a required width and wound up, and then processed again by a slitter rewinder of the above-mentioned type. . Therefore, if the length of the winding shaft of the slitter rewinder of the above-mentioned type can be made longer than before so that a wide band-shaped sheet can be processed, this problem is solved. For that purpose, the deflection of the winding shaft must be suppressed to a certain amount or less.

Conventionally, as means for suppressing deflection of a winding shaft in a winding device using a winding shaft supported at both ends, for example, as disclosed in Japanese Patent Publication No. 62-23692, a winding roll during winding is used. There is a support roller that supports the lower surface.

[0005] In order to prevent winding failure due to the bending of the winding shaft, means for compensating the bending of the winding shaft is disclosed in Japanese Utility Model Application Laid-Open Publication No.
As shown in 2-53270, metal is provided inside the support portion at both ends of the winding shaft, and an upward load is forcibly applied by a hydraulic cylinder or the like to correct the bending of the winding shaft due to the weight of the winding roll. There is a deflection correction device.

However, the support roller for supporting the lower surface of the take-up roll is effective for winding a single wide band-like sheet, but is capable of winding a large number of divided narrow band-like sheets in common. The following problem arises when winding is performed simultaneously on a shaft. That is, in general, the strip-shaped sheet has uneven thickness, and when the sheet is divided and wound, the uneven thickness is accumulated and an outer diameter difference occurs between the winding rolls. If the lower surface of the winding roll supported by the common winding shaft and having a difference in outer diameter is supported by the supporting roller, the supporting load is concentrated on the winding roll having the larger outer diameter. Accordingly, when the support load of the support roller is concentrated on a specific take-up roll, when winding a strip-shaped sheet having a small division width onto a take-up roll having a large outer diameter, winding failure such as winding collapse is likely to occur.

Further, in a deflection correcting device for forcibly applying an upward load to the winding shaft by a hydraulic cylinder or the like, the magnitude of the upward load is accurately controlled according to a change in the weight of the winding roll due to the winding of the winding roll. Must. Therefore, control becomes complicated.

Accordingly, the present invention has been made in view of the above problems,
A slitter that divides the strip into multiple strips and
Both ends are supported by the bearing at the winding position between a pair of frames.
Completed , two winding shafts arranged in parallel and a take-up roll completed
After that, pull out the winding shaft from the winding position and return to the winding position
A reel removal and return mechanism that can be
And a take-up roll receiving device that can be raised and lowered
And divided into multiple sections by the above slitter
In a slitter rewinder which alternately divides the strip-shaped sheet into the two winding shafts and winds them around each of the winding cores fitted on the outer periphery of the winding shaft, the winding shaft can be increased without increasing the outer diameter of the winding shaft. It is an object of the present invention to increase the length of the belt-shaped sheet so as to be able to handle a band-shaped sheet wider than before, thereby improving the productivity in the band-shaped sheet division winding step.

[0009]

In order to achieve the above object, a slitter rewinder of the present invention comprises a winding roll receiving device.
