DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web winding apparatus applied to a rewinding machine or a cutting machine and winding a long web around an outer peripheral surface of a winding core.

[0002]

2. Description of the Related Art Generally, a long web, for example, a rewinding machine for automatically winding a long film on a core, or a long film having a predetermined width by cutting a wide film material. In the cutting machine for automatically winding the long film around the core after obtaining the above, the long film is wound on the outer peripheral surface of the core by a predetermined length under the rotating action of the core. At the same time, the end of the long film is cut (cross-cut) to obtain a product.

Hitherto, various proposals have been made for automatically performing this kind of winding operation. For example, a slitter disclosed in Japanese Patent Application Laid-Open No. 6-234444 is known. In this prior art, after a narrow web is wound on a core at the lower end of a core holding frame to a predetermined full length, a full roll take-out transporter rises with respect to the core holding frame, and the upper surface thereof moves upward. Supports the full roll. Then, the full roll is removed from the core holding frame, and the full roll take-out carrier descends with the full roll mounted thereon.

Then, when the core holding frame moves and the new core comes into contact with the touch roller, the cutting blade cuts the narrow web in the width direction. Thereafter, one of the cut ends of the narrow web is wound around a full roll, and the other is wound around a new core, and a new winding process is started.

[0005] By the way, as described above, when the full roll take-out carrier puts the full roll, specifically,
As shown in FIG. 20, the narrow web 4 is wound around the core 3 by a predetermined full length under the rotation of the core rotation shaft 2 provided on the core holding frame 1, and the core 3 is fully wound. After the roll 5 is obtained, the full roll take-out and transport vehicle 6 is lifted, and the full roll 5 is placed on the full roll take-out and transport vehicle 6.

[0006]

However, in the above-mentioned prior art, if the narrow web 4 is not wound up to a certain length on the winding core 3, the full roll 5 becomes small in diameter, and the full roll 5 becomes full. When the roll take-out carrier 6 moves up, it may interfere with the core holding frame 1. For this reason, the diameter of the full roll 5 is relatively large (substantially full).
It is pointed out that the process of taking out the full roll 5 cannot be performed unless the above condition is satisfied.

Therefore, usually, the width of the full roll take-out carrier 6 is set to be equal to or less than the minimum width of the full roll 5, and the size of the full roll 5 having various widths is changed. However, in the full roll 5 having various widths, particularly when the full roll 5 having the maximum width is to be paid out, the contact surface pressure between the full roll take-out carrier 6 and the full roll 5 becomes high. The full roll 5 may be damaged. In addition, there is a problem that the size switching structure becomes complicated and the equipment cost rises.

The present invention solves this kind of problem, and a web winding apparatus capable of efficiently winding a web with a simple configuration, easily adapting to changes in width and winding diameter. The purpose is to provide.

[0009]

In a web winding apparatus according to the present invention, a core rotating mechanism for rotating a core, a winding mechanism for guiding a long web to an outer peripheral surface of the core,
A product receiving mechanism for receiving and paying out the wound body obtained by winding the long web around the core from the core rotating mechanism, and the core rotating mechanism includes the winding mechanism and the product receiving mechanism. The dimension is set to be smaller than the outer diameter of the core corresponding to the portion where the mechanism contacts.

For this reason, even if the length of the long web with respect to the winding core is considerably short, the winding mechanism and the product receiving mechanism do not interfere with the winding core rotating mechanism, and the width of the winding body is reduced. It is possible to easily cope with a change in the outer diameter and the outer diameter.

The core rotation mechanism includes a core chuck that engages both ends of the core to rotate the core, and a winding arm on which the core chuck is rotatably mounted. I have. Therefore, by setting the dimensions of the core chuck and the winding arm, interference with the winding mechanism and the product receiving mechanism is surely prevented, and with a simple configuration,
It can correspond to any width and any winding length of the wound body.

Further, the nip roller and the product receiving mechanism constituting the winding mechanism are set to have a size equal to or greater than the maximum width of the long web in the width direction of the long web. Thereby, even if the width dimension of the wound body is switched, the contact surface pressure between the product receiving mechanism and the wound body does not increase, and it is possible to effectively prevent the wound body from being damaged. Become. In addition, when the width of the wound body is changed, it is not necessary to switch the size of the nip roller and the product receiving mechanism, which simplifies the equipment and is economical.

Here, the nip roller and the product receiving mechanism are arranged within a range of 180 ° with respect to the outer peripheral surface of the core, while the winding arm is provided with the remaining 180 ° with respect to the outer peripheral surface of the core. Are arranged within the range. For this reason, even if the core rotation mechanism is arranged at an arbitrary position in the width direction of the wound body, the core rotation mechanism does not interfere with the nip roller and the product receiving mechanism. Furthermore, it is possible to easily and surely cope with a change in the winding direction of the long web and a change in the winding length, and it is excellent in versatility.

Further, the core chuck includes a fixing member for fixing the core chuck to a rotating shaft provided on the winding arm, a plurality of expansion / contraction claw members for holding an inner peripheral surface of the core, A wedge member coupled to an advance / retreat rod disposed in the rotary shaft so as to be able to advance / retreat, and a wedge member for integrally expanding / contracting the expansion / contraction claw member; and a rod fixing member for attaching the wedge member to the advance / retreat rod. ing. Accordingly, a plurality of core chucks prepared for a plurality of cores having different outer diameters can be easily and firmly attached to the winding arm, and the work of exchanging the core chucks can be easily performed.

It is arranged within a range of 180 ° on the upper side. For this reason, even if the core rotation mechanism 58 is arranged at an arbitrary position with respect to the axial direction of the core 28 (the width direction of the long film 24a), the core rotation mechanism 58 is used for the winding mechanism 110 and the product receiving device. There is no interference with the mechanism 64. Therefore, it is possible to easily and reliably cope with a change in the winding direction of the long film 24a and a change in the winding length with a simple configuration, and an effect of excellent versatility is obtained.

As shown in FIGS. 5 and 6, the core chuck 90b moves the rod 126 forward and backward under the driving action of the cylinder 126 to expand and contract the wedge member 140. The surface can be held easily and reliably. And when the small diameter core 28 is used,

Here, when removing the core chuck 90b from the winding arm 88b, first, the cover member 17
After removing 8, the rod fixing member 142 is moved in the radial direction of the advance / retreat rod 124 along the long hole 174 with the fixing screw 172 loosened to a predetermined position. As a result, the distal end of the advance / retreat rod 124 is
42 from the small diameter side to the large diameter side in the hole 176 of 42,
The wedge member 140 and the rod fixing member 142 are integrally removed from the advance / retreat rod 124.

On the other hand, in the fixing member 136, as shown in FIG. 7, when the fixing screw 150 is loosened to a predetermined position,
The support portion 148 moves in a direction away from the cylindrical portion 144 via the elastic force of the spring 152. For this reason, the convex portion 154 of the support portion 148 is separated from the groove 156 of the rotating shaft 122, and the fixing member 136 is removed from the rotating shaft 122. Accordingly, the work of exchanging the core chucks 90b and 90c is easily and quickly performed, and the detachment of the fixing screws 150 and 172 is effectively prevented, so that the entire work can be easily simplified.

In this embodiment, the long films 24a and 24b have been described as webs, but the present invention is not limited to this, and the present invention can be applied to various webs such as resin sheets and paper.

According to the web winding apparatus of the present invention,
Since the core rotation mechanism corresponds to a portion that comes into contact with the winding mechanism and the product receiving mechanism and is set to a dimension smaller than the outer diameter of the core, the winding length of the long web with respect to the core is equivalent. Even if the length is short, the winding mechanism and the product receiving mechanism do not interfere with the core rotating mechanism. Accordingly, it is possible to easily cope with a change in the width dimension and the outer diameter dimension of the wound body, and it is possible to efficiently wind a long web with a simple configuration.
