Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thickness measuring device for measuring the thickness of a sheet-shaped member such as a synthetic resin sheet or film.

[0002]

[Prior art]

 Generally, a non-contact type measuring device is used as a measuring device for measuring the thickness of a sheet-shaped member such as a synthetic resin sheet or film. This non-contact type measuring device measures the thickness of the sheet-shaped member by measuring its transmittance using radiation or beta rays. When striking, it was not possible to make accurate measurements, and when dealing with waviness, for example, there was a drawback that a complicated control mechanism was required. Therefore, a contact type device is used as a device for measuring the thickness of such a sheet-shaped member.

Conventionally, this contact-type thickness measuring device measures the thickness of a sheet-shaped member by pressing the measuring roller against the surface and measuring the displacement of the measuring roller. . Of course, in this case, the measuring roller is mounted so as to rotate in the direction along the moving direction of the sheet-shaped member.

[0004]

[Problems to be solved by the device]

 However, according to the configuration of the conventional contact-type thickness measuring device described above, when the measurement roller is moved in the width direction in order to measure the thickness of the sheet-shaped member in the width direction, the measurement roller is changed to the sheet-shaped member. Since it is in contact with the surface and the rotation direction is the moving direction of the sheet-shaped member, the surface of the sheet-shaped member is scratched. For this reason, when measuring along the width direction, it is necessary to lift the measuring roller once from the sheet-shaped member, move it for a specified distance, and then lower it, and then measure the thickness at that point. The thickness of the member cannot be continuously measured in the width direction, and the measuring roller has to be raised and lowered, which is very time-consuming.

Therefore, an object of the present invention is to provide a sheet-shaped member thickness measuring device capable of continuously and quickly measuring the thickness of the sheet-shaped member in the width direction.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the first means of the present invention is a measuring device for measuring the thickness of continuously moving sheet-like members, wherein a base roll having the sheet-like members is provided in the main body frame. The guide member is provided rotatably around the horizontal axis, and the guide member is provided parallel to the axial direction of the base roll to movably guide the moving body. A support for rotatably supporting a measuring roller which is provided so as to be movable up and down in a plane orthogonal to the axis of the base roll and which is capable of coming into contact with the sheet-shaped member moved on the base roll from above is rotatably mounted on the lifting member. A thickness measuring device for a sheet-shaped member, which is rotatably held in a plane parallel to a tangential plane of a base roll and equipped with a sensor for measuring the thickness of the sheet-shaped member.

In order to solve the above-mentioned problems, a second means of the present invention is a measuring device for measuring the thickness of continuously moving sheet-shaped members, wherein a sheet-shaped member is attached to a main body frame. A base roll to be guided is provided rotatably around a horizontal axis, and a guide member is provided in parallel with the axial direction of the base roll to guide the movable body to the movable body and to move the movable body to the movable body. The elevating member is provided so as to be able to ascend and descend in a plane orthogonal to the axis of the base roll, and the elevating member is provided with a spherical bearing for measurement that can come into contact with a sheet-like member moving on the base roll from above. A thickness measuring device for a sheet-shaped member, comprising a sensor for measuring the thickness of the sheet-shaped member while holding the same.

[0008]

[Action]

 According to the above configuration, as the contact for the sheet-shaped member, the measuring roller whose direction can be freely changed or the measuring sphere held by the spherical bearing is used. With the sphere in contact with the sheet-shaped member, it can be moved smoothly in the width direction without damaging the sheet-shaped member, and therefore the thickness of the sheet-shaped member can be made continuous in the width direction. It can be measured quickly and quickly.
