Film intermittent carrying device and film intermittent carrying method

Abstract

To increase a carrying speed of a film without generating scratches, etc., on the intermittently carried film (12). A film intermittent carrying device is provided, including: a film delivery mechanism (22); a delivering and accumulating mechanism (23) accumulating the film and discharging the film (12) in a short period of time; a winding and accumulating mechanism (43) accumulating the film (12) while simultaneously discharging in an amount corresponding to an amount of the film discharged in a short period of time; and a film winding mechanism (42) taking-up the film constantly at a specified rate. The delivering and accumulating mechanism (23) includes: first and second fixed rollers (24, 25); an upstream-side movable roller (26) moving to pass through a middle position between the first and second fixed rollers (24, 25); and an upstream-side friction preventive unit (27) not allowing a friction to occur between the film (12) and the upstream-side movable roller (26). The winding and accumulating mechanism (43) includes: third and fourth fixed rollers (44,45); a downstream-side movable roller (46) moving to pass through the middle position between the third and fourth fixed rollers (44, 45); and a downstream-side friction preventive unit (27) not allowing the friction to occur between the film (12) and the downstream-side movable roller (46).

Description

technical field [0001] The present invention relates to an intermittent feeding device for intermittently feeding a long film, and an intermittent feeding method for a film. Background technique [0002] In the printing industry and the like, after conveying a film to be printed, it is temporarily stopped, after predetermined printing is performed on the stationary film, it is conveyed again, and printing is performed again on the stationary film again. Such printing is also known to be used in the manufacture of solar cells, flat panel displays (FPD), and MLCC (Monolithic Ceramic Chip Capacitors). The film is conveyed. Furthermore, as a device for intermittently conveying a film in this way, an intermittent conveying device for a film is conventionally known. The intermittent conveying device for a film includes: a lead-out side for leading out a predetermined amount of film; The take-up side is provided separately from the lead-out side, and a predetermined amount of fil...

Problems solved by technology

Therefore, even if it is a winding roll or a winding roll, it is difficult to rotate suddenly from a stopped state, or to stop immediately from a rotating state

Therefore, if the conveyance speed of the intermittently conveyed film is increased in the state of being wound on the outer periphery of the unwinding roller or the winding roller, the speed of the outer periphery of the roller, which is difficult to rapidly accelerate or decelerate, and the speed of the winding There is a difference between the conveying speed of the film on which it is rapidly accelerated and decelerated, causing friction due to the film being conveyed slidingly on the outer periphery of the roller, and sometimes causing flaws in the film due to this friction
