[Structure] An ironing roll 13 is attached to the tips of a pair of swing arms 14 so as to be able to approach and separate from a winding drum 12. The ironing roll 13 is made of rubber. Both ends of the support shaft 21 penetrating the axis of the ironing roll 13 are received by a half-split bearing 26, which includes a bearing body 26A fixed to the swing arm side and a bearing cap 26B that is detachably attached to the bearing body 26A. Rubber bushes 22 are respectively interposed between both ends of the support shaft 21 and the bearing 26.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a winding device that winds a rolled aluminum foil into a coil.

[0002]

[Prior Art]

 As this type of device, it is known that an ironing roll is attached to the tips of a pair of swing arms so as to be able to approach and separate from the winding drum, and the ironing roll is made of iron. There is.

[0003]

[Problems to be solved by the device]

 In the above apparatus, since the ironing roll is made of iron, in the case of high-speed rolling, noise is large and winding misalignment may occur. Therefore, it is also considered to use a rubber one for the ironing roll. It is known that the use of rubber ironing rolls eliminates the above noise and winding misalignment problems, but aluminum foil powder adheres to the rolls, and the adhered powder peels off to cause dirt. There are problems that must be resolved.

An object of the present invention is to provide an aluminum foil winding device that solves the above problems.

[0005]

[Means for Solving the Problems]

 The aluminum foil take-up device according to the present invention is an aluminum foil take-up device in which an ironing roll is attached to the tips of a pair of swing arms so that the ironing roll can approach and separate from the take-up drum. However, both ends of the support shaft, which is made of rubber and penetrates through the axis of the ironing roll, are received by half-divided bearings that consist of a bearing body fixed to the swing arm side and a bearing cap that is removable from the bearing body. A rubber bush is interposed between both ends of the support shaft and the bearing, respectively.

[0006]

[Action]

 In the aluminum foil winding device according to the present invention, since the ironing roll is made of rubber, the above noise and winding deviation do not occur.

Further, both ends of the support shaft, which penetrates the axis of the ironing roll, are respectively received by a half-divided bearing including a bearing body fixed to the swing arm side and a bearing cap detachable from the bearing body. Therefore, it is possible to easily replace the ironing roll by removing the bearing cap.

Further, since rubber bushes are respectively interposed between the both ends of the support shaft and the bearing, it is not necessary to perform centering work especially when replacing the ironing roll.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The rolling of the aluminum foil is roughly divided into three steps of a rough rolling step, a medium rolling step and a finish rolling step. Among these three processes, the winding device according to the present invention, which will be described in detail below, is arranged in the rough rolling process and the medium rolling process, and the conventional winding device described at the beginning is arranged in the finishing rolling process. ing.

As shown in FIG. 1, the aluminum foil winding device includes a winding drum 12 arranged in front of the device main body 11 and winding the aluminum foil F in a coil shape, and an aluminum foil to be wound. An ironing roll 13 that is lightly pressed against F and a pair of rocking rolls that are attached to the tip end of the ironing roll 13 and that are attached to the device frame 11 so that the ironing roll 13 can be moved toward and away from the winding drum 12. A moving arm 14 and a fluid pressure cylinder 15 for rocking the rocking arm 14 are provided.

The ironing roll 13 is made of rubber. As shown in detail in FIG. 2, the support shaft 21 penetrates the shaft center of the ironing roll 13 so that both ends thereof are projected (only one end is shown in the drawing), and the rubber bush 22 is fitted over the protruding end. Has been. A pair of guide bars 23 extending parallel to each other in the arm length direction is provided at the tip of the swing arm 14, and a rotatable roll position adjusting screw rod 24 is provided between the guide bars 23. ing. A roll mounting block 25, which is screwed into a screw rod 24, is slidably supported on both guide bars 23.

A half bearing 26 is provided on the roll mounting block 25. The bearing 26 comprises a bearing body 26A integrated with the roll mounting block 25, and a bearing cap 26B which is attached to and detached from the bearing body 26A by a bolt 27. Semi-circular grooves 28 and 29 are formed on the facing surfaces of the bearing body 26A and the bearing cap 26B, respectively, and these 28 and 29 grooves are united to form an annular space for accommodating the rubber bush 22. There is.

The replacement of the inning roll 13 may be performed by the following procedure. First, use an aluminum foil winding drum replacement coil car (not shown), and then mount a new ing roll to be replaced on the coil car. Move the coil car with the new eyening roll under the old eyening roll 13 attached to the swing arm 14, lower the swing arm 14, and once receive the old eyening roll 14 with the coil car. deep. In this way, when the bolt 27 is removed to separate the bearing cap 26B from the bearing body 26A and the arm 14 is raised, the old inning roll 13 is left on the coil car. Next, replace the new and old Eining rolls 13, lower the arm 14, cover the bearing cap 26B on the support shaft of the new Eining roll, and use the bolts 27 to mount the bearing body 26A and the bearing cap. Combine 26B. Then, when the coil car on which the old inning roll 13 is placed is moved to a predetermined standby position, the work of exchanging the inning roll is completed.

[0015]

EFFECTS OF THE INVENTION According to this invention, since problems of noise and winding deviation do not occur, high-speed rolling can be performed without any trouble.

Further, since the ironing roll can be easily replaced by detaching the bearing cap, the ironing powder can be replaced as needed without causing a problem due to the powder of the aluminum foil.

Further, since it is not necessary to perform centering work particularly when replacing the ironing roll, the coining roll replacement work can be performed more easily.
