Embodiment Construction
[0027] Embodiments of the present invention will be described below with reference to the drawings. In addition, in the present invention, the optical member is not particularly limited as long as it is a flexible strip-shaped functional film such as a polarizing film, a retardation film, and a brightness enhancement film. case is described as an example.
[0028] figure 1 It shows the schematic structure of the optical film cutting apparatus which not only implements the optical film cutting method of this invention, but also includes the process before stacking the cut optical film and carrying out the optical film.
[0029] The apparatus of this embodiment consists of a film supply unit 1 that discharges and supplies the polarizing film F, a cutting mechanism 3 that cuts the polarizing film F into a film having a predetermined length in the conveying direction, and conveys the polarized light after cutting at the end of the conveying path. The conveyance mechanism 4 of th...

The present invention provides a transport method of an optical film and a device using the transport method. In the conveyance method of this optical film, in the process of conveying the belt-shaped optical film (F), this optical film (F) is cut|disconnected into the single piece of predetermined length. After that, the optical film (F) after cutting is intermittently conveyed while feeding out the optical film (F) of a predetermined length so that the next cutting position reaches the cutting action position, and the optical film (F) on the front side in the advancing direction of the intermittent conveying process is intermittently conveyed. The rear end of the film (F) has been sent out to the continuous conveyance process after the intermittent conveyance process when the intermittent conveyance process performs the next intermittent conveyance. At this time, the cut optical film (F) is delivered to the continuous conveyance process in which the optical film (F) is continuously conveyed, which is continuous with the downstream side of the intermittent conveyance process.
Description
[0001] This application is a divisional application of the application number 200880024712.X, the application date is January 14, 2010, and the invention name is the delivery method of optical film and the device using the method. technical field [0002] The present invention relates to a transport method of an optical film capable of transporting optical films such as a polarizing film, a brightness enhancement film, and a retardation film bonded to a substrate such as a liquid crystal panel with high precision without causing damage, etc., and an apparatus employing the method. device. Background technique [0003] A conventional method of conveying a single optical film is performed as follows. When handing over a sheet-shaped workpiece between the continuous upstream and downstream conveyors, a sensor is used to detect the moment when the front end of the sheet-shaped workpiece passes the upstream conveyor, and from the downward direction between the upstream and downst...
