Description

The present invention relates to a roll holder for rotating a rolled sheet used when, for example, a wide synthetic resin sheet wound around a paper tube (core tube) or the like is unwound.

When repainting a body of an automobile or the like, a non-painted portion or a portion to which paint should not adhere (for example, a window glass, a mirror, a headlight, etc.) is covered with a synthetic resin film (sheet). This synthetic resin film is generally wide (for example, 0.9 to 1.8 m) and a long one is rolled around a core tube. Accordingly, the rolled synthetic resin film is appropriately unwound and cut into a predetermined length and used as a paint cover or the like.
As such an apparatus for gradually unwinding a synthetic resin film from a rolled synthetic resin film, for example, a device as described in Patent Document 1 has been proposed.

JP 2002-283279 A

However, the device described in Patent Document 1 is a large-scale device, and a synthetic resin film having a predetermined length must be cut out from a device installed in a specific place, like a synthetic resin film used for automobile painting work. In addition, there is a problem that workability is poor for those of different lengths.

The present invention has been made in view of such circumstances, and it has good workability when a roll-like sheet (that is, a synthetic resin film) is unwound to obtain a synthetic resin film having a necessary length, and is further manufactured. An object of the present invention is to provide a roll-and-roll-type rotating holder with low cost.

The roll holder for a rolled sheet according to the first aspect of the present invention is a roll holder for a roll sheet used as an auxiliary when unrolling a sheet wound around a core tube. A short tube portion that can be inserted into the lower end of the core tube, a disc portion that is fixed to the lower end of the short tube portion with an axis centered on the short tube portion, and a bottom center of the disc portion. An angle formed by a straight line in contact with the protruding part through the outer lower end of the disk part and the disk part is 5 to 25 degrees. Is in range.

In using this roll-wrapped sheet-like rotating holder, the core tube around which the synthetic resin film is wound, that is, the core tube of the roll-wrapped sheet-like material is substantially upright, and the rotating holder is short-circuited. Insert into the tube. As a result, when the lower end portion of the rolled sheet is in contact with the disk portion, the entire upper portion is held upright by holding the upper end with a hand or the like, the protruding portion can easily rotate the rolled sheet about the floor. Become. In this state, the wound synthetic resin film is unwound and cut to the required length for use. When the operation is interrupted, it is leaned against a wall or the like while the roll-rolled sheet-like rotating holder is mounted on the core tube. In this case, the roll-wrapped sheet-like material is inclined more than the angle formed by the straight line that contacts the projection through the outer lower end of the disk part and the disk part, and the edge of the disk part contacts the floor surface. If it does so, the rotation of the roll-up sheet-like thing which leaned can be performed. If this angle is less than 5 degrees, it will be difficult to turn the roll-wrapped sheet when the roll sheet with the rotating holder attached is slightly tilted and the disk portion will hit the bottom surface, and if this angle is greater than 25 degrees. The angle at which the peripheral edge of the disc portion is brought into contact with the floor surface becomes large, and the workability is poor.

Further, a roll-wrapped sheet-like rotating holder according to the second device is the roll-wrapped sheet-like rotating holder according to the first device, wherein the disk portion has a diameter outside the short tube portion. It exists in the range of 2.5-5 times the diameter, and if it is this range, the lower end of the sheet-like material wound around the core pipe part can be received stably.
As a result, in addition to the core tube of the rolled sheet material, the lower end of the rolled sheet material is also supported by the disk portion, and the rotating holder can be attached to the sheet material rolled on the core tube. Stabilize.

According to a third aspect of the present invention, there is provided a roll-wrapped sheet-like rotating holder according to the second invention, wherein the protruding portion is hemispherical, the hemispherical protruding portion. Is in the range of 0.8 to 1.2 times the outer diameter of the short tube portion. Thereby, even if the roll-wrapped sheet-like material on which the rotary holder is mounted is tilted at a slight angle during the operation, the roll-wrapped sheet-like material can be smoothly rotated.

And the roll holder of the roll sheet according to the fourth device is the roll holder of the roll sheet according to the first to third devices, and the periphery of the disc part is made of rubber or elastic. A non-slip ring having a U-shaped cross section made of plastic having

The roll holder of the roll-wrapped sheet of the present invention can be used to easily unroll the roll-wrapped sheet-like object.
In addition, the roll-wrapped sheet-like material with the roll-wrapped sheet-like rotation holder attached is easy to move, and can be kept rotating even if it is tilted within the range where the peripheral edge of the disk portion does not contact the floor surface. The tool can be freely rotated, and the work of unwinding the sheet-like material for the required length can be easily performed from the roll-wound sheet-like material attached to the rotary holder.
Then, when the roll-wrapped sheet-like object on which the rotating holder is mounted is tilted until the peripheral edge of the disk part comes into contact with the floor surface, the disk part comes into contact with the floor surface and becomes a brake, and this roll-wrapped sheet-like object further slides. Can be prevented from falling.
Since the lower end of the roll-wrapped sheet-like material to which the rotating holder is attached is protected by the disc portion, no wrinkles are attached.
In particular, when a non-slip ring having a U-shaped cross section made of rubber or elastic plastic is attached to the peripheral edge of the disc part, the roll-wrapped sheet-like object equipped with this rotating holder is inclined on a wall or the like. When dripping, the non-slip ring acts and is easily held in that position.
