Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detaching a web roll wound on a core as a narrow web by slitting a wide web, from a winding shaft.

[0002]

2. Description of the Related Art A slitter apparatus slits a wide web such as a paper or a plastic film in a longitudinal direction, and cuts the slit narrow web so that the ends of a web roll (rolled product) do not overlap each other. 2. Description of the Related Art A device is generally used which sorts two winding shafts which are not arranged on a line and winds each narrow web. In a slitter device, it is necessary to slit a wide web into a predetermined width and wind it up on a core mounted on a winding shaft to form a plurality of web rolls, and then take these web rolls out of the slitter device. In order to take the web roll out of the slitter in this manner, conventionally, the web roll is removed together with the winding shaft using a hoisting device such as a hoist or a crane, and the web roll is directly transferred to the transfer trolley by the hoisting device or temporarily. In general, a web roll is conveyed to a position and a web roll is removed from a winding shaft along the axis of the winding shaft. However, such a method of removing the entire take-up shaft requires not only equipment such as a hoist and a crane, but also takes time and effort to remove, transport, and remove the take-up shaft, and also requires space for work. In addition, there is a problem that the operation rate is reduced because the slitter must be stopped for a long time. Further, there is a problem in that a replacement winding shaft must be prepared, and a management and storage space for the winding shaft is required.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention makes it possible to efficiently attach and detach a web roll to and from a slitter device, reduce the size of the device to reduce the occupied space, and improve the workability. It is an object of the present invention to provide a web roll attaching / detaching apparatus in a slitter apparatus having a good condition.

[0004]

a, 44b. Also, the winding shaft 20
a and 20b are detachably connected to drive shafts 47a and 47b by convex joints 46a and 46b, and the drive shafts 47a and 47b are connected to a drive motor 49 via a belt 48.
It is connected to. In addition, the driving device is a winding shaft 20a, 20.
b is not limited to be connected to the tip of the winding shaft 20a,
It may be connected to the base end of 20b. Winding shaft 20a, 2
0b and the screw shafts 28a, 28b have the same configuration. The rotating frame 34 is attached to the frame 40 via a support shaft 36, and is rotatable in the horizontal direction. When the winding of the web roll is completed and the convex joints at the distal ends of the winding shafts 20a and 20b are detached, the rotating frame 34 is rotated in the horizontal direction by a driving device (not shown) with the vertical supporting shaft 36 as a fulcrum. The winding shafts 20a, 20b and the screw shafts 28a, 2
8b moves in the horizontal direction (A direction), and the winding shaft 2
The leading ends of Oa and 20b are released and located outside the front machine frame 60 of the slitter device 10. Next, the drive motor 50 is operated to rotate the screw shafts 28a and 28b,
The nut members 38a and 38b screwed to the screw members 28a and 28b move toward the distal ends of the screw shafts 28a and 28b, and the support member 26 moves along the screw shafts 28a and 28b, and the pressing member attached to the support member 26 Reference numerals 24a and 24b depress the web roll 22 and detach the web rolls 22 from the leading ends of the winding shafts 20a and 20b.

As shown in FIG. 5, a support member 26 is provided between screw shafts 28a and 28b, and nut portions 38a and 3a screwed to the screw shafts 28a and 28b at both ends of the support member 26.
8b are provided. The screw shafts 28a and 28b are connected to a drive motor 50 so that they can rotate forward and backward. The screw shafts 28a and 28b rotate forward, the support member 26 moves rightward in the drawing via the nut portions 38a and 38b screwed together, and the support member 26 moves leftward in the drawing by reverse rotation. Thus, the screw shafts 28a and 28b are
0a, 20b, the supporting member 26 is synchronously moved from above and below, so that the weight of the web roll 22 wound around the core increases, and the core and the winding shaft 20a , 20b, or when the gap between the inner diameter of the core and the outer diameter of the winding shafts 20a, 20b is small and catching occurs during attachment / detachment, the attachment and detachment of the upper and lower web rolls 22 can be performed smoothly. Can be performed.

Next, the operation of the web roll attaching / detaching apparatus in the above-mentioned slitter apparatus 10 will be described with reference to FIG.

The wide web 12 is slit into a plurality of narrow webs 18 by a cutter 16, and the narrow webs 18 are wound on cores mounted on each of the winding shafts 20a and 20b to a predetermined winding diameter. Upon completion, each web roll 22 is subjected to a terminal process such as sticking an adhesive tape to the terminal, and then a detachment operation is performed.

As the detaching operation, first, the winding shaft 20a,
The convex joints 46a and 46b connecting the drive shafts 20a and the drive shafts 47a and 47b are detached. Then, stopper 4
4a and 44b are released, and the rotating frame 34 is horizontally moved (A-
B direction). At this time, the winding shafts 20a, 20b
The screw shafts 28a and 28b are also rotated integrally.
The rotation angle depends on the winding diameter of the web roll 22, but is preferably in the range of 15 to 45 degrees.

When the rotating frame 34 is rotated in the horizontal direction (A direction) and the leading ends of the winding shafts 20a and 20b are released, the drive motor 50 operates and the screw shafts 28a and 28b rotate forward. Starting, the support member 26 advances in the C direction via nut portions 38a, 38b screwed to the screw shafts 28a, 28b, and the pressing members 24a, 24b attached to the support member 26 move the web roll 22. It is pressed and detached from the leading ends of the winding shafts 20a and 20b.

The web roll 22 detached from the winding shafts 20a and 20b is, for example, a web roll receiving truck 54 having web roll receiving shafts 52a and 52b as shown in FIG.
, And can be carried out of the slitter apparatus 10, but the carrying-out means is not limited to this.

Winding shaft 20 with web roll 22 detached
a and 20b are equipped with a new core,
The rotating frame 34 on which the supporting shafts a and 20b are supported rotates in the horizontal direction B with the supporting shaft 36 as a fulcrum and returns to the winding position, and the winding shafts 20a and 20b are driven via the convex joints 46a and 46b. The next winding is started by being connected to 47a and 47b.

[0017]

According to the web roll attaching / detaching device in the slitter device of the present invention, when the rotating frame is rotated about the vertical direction as the support shaft, the winding shaft is rotatable about the base end as a fulcrum. The tip of the winding shaft is released, and the core mounted on the winding shaft is mounted on a web roll detaching device including a screw shaft provided above and below the winding shaft and a supporting member and an extruding member driven by the screw shaft. The wound web roll can be easily attached and detached, and the stop time of the slitter device can be shortened and the operation rate can be improved. Further, since there is no need to perform an operation such as removal of the entire winding shaft, a simple and space-saving slitter device can be obtained.
