Rack for film delivery

Abstract

The invention provides a rack for film delivery with no damage to core and good operability and capable of fixing the film roller on the rack to prevent the axial movement. In the rack for film delivery, a side rack between two stands of the short side connected with a rectangular rack base comprises a recess core accommodating part used for accommodating core and having an opening on the upper surface thereof, a recess core movement prevention plate on the outer surface of the core accommodating part and having an opening on the upper surface thereof, and a core pressing part used for upwards pressing the core inserted in the core accommodating part, wherein the bottom of the recess of the movement prevention plate is as high as or below the extending surface of the bottom of the recess of the core accommodating part, so that two sides of the recess of the movement prevention plate are more inward than the two sides of the recess of the core accommodating part, thereby preventing the movement of the core. The recess core movement prevention plate can be replaced with a couple of core movement prevention plates more inward than two sides of the recess of the core accommodating part.

Description

technical field [0001] The present invention relates to a stand for film conveyance for supporting, in a suspended state, a roll for winding a wide-width film formed of a material such as a polarizing film on a core, at both left and right ends of a core. Background technique [0002] Films such as polarizing light are used in liquid crystal displays, and the production of the polarizing film is performed by receiving a supply of a raw material film wound around a tubular metal core. Therefore, it is necessary to convey the raw film wound up on the core from the raw film manufacturing process to the polarizing film manufacturing process without damage or deformation. In the past, a transport stand for supporting and transporting the film in a suspended state has been discussed. However, in recent years, the size and cost of liquid crystal displays have been increasing, and the raw material film has been required to be wider and thinner. With its development, the existing tr...

AI Technical Summary

Problems solved by technology

However, the more the movement of the core is restricted, the greater the force acting on the core itself, resulting in a problem that the possibility of deformation and damage to the core increases.

For example, as described in Patent Document 1, if only the inner lower part of the end surface of the core material is fixed, the vibration of the film roll cannot be sufficiently suppressed. However, as described in Patent Document 2 or Patent Document 3, if the end surface of the core material is fixed damage to the core material is likely to be greater if all or most of the
