Title:
フィルムの間欠搬送装置及びフィルムの間欠搬送方法
Document Type and Number:
Japanese Patent JP5430019
Kind Code:
B2
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).
