Abstract
After a roll supply carriage housing rolls in a light-shielded case is coupled to a film manufacturing apparatus, shutters are opened, and a roll retainer shaft and a roll loading shaft are connected to each other. A motor in a roll transferring apparatus is energized to transfer one of the rolls into the roll transferring apparatus. Then, a rotary table is turned to supply the transferred roll to a given region in the film manufacturing apparatus.
Claims12
A method of transferring a roll, comprising the steps of:
- bringing a roll loading shaft into engagement with a roll retainer shaft which holds a plurality of rolls thereon;
- releasing said rolls from being held on said roll retainer shaft;
- supporting one of said rolls;
- moving and transferring said supported one of the rolls along said roll retainer shaft onto said roll loading shaft;
- and
- fixing said one of the rolls to said roll loading shaft,
- wherein a tip end of said roll retainer shaft is pressed by a tip end of said roll loading shaft to release said rolls from being held on said roll retainer shaft under pressing forces, and
- wherein a mechanism associated with said roll retainer shaft is actuated by a rotating action of a mechanism associated with said roll loading shaft to move said rolls along said roll retainer shaft.
An apparatus for transferring a roll held on a roll supply carriage, comprising:
- a roll loading shaft for engaging a roll retainer shaft of said roll supply carriage which holds a plurality of rolls;
- releasing means for releasing said rolls from being held on said roll retainer shaft, said releasing means having a pressing member disposed at an axial center of said roll loading shaft for pressing an axial center of said roll retainer shaft to release said rolls from being held on said roll retainer shaft;
- transferring means for moving and transferring one of the rolls along said roll retainer shaft onto said roll loading shaft, said transferring means comprising engaging means disposed at an axial center of said roll loading shaft for engaging a ball screw disposed at an axial center of said roll retainer shaft and rotating means for rotating said engaging means of said roll loading shaft thereby to rotate said ball screw of said roll retainer shaft;
- and
- fixing means for fixing said one of the rolls to said roll loading shaft,
- wherein said one of the rolls held on said roll retainer shaft is transferred onto said roll loading shaft by a nut which moves upon rotation of said ball screw.
A roll supply carriage comprising:
- a roll retainer shaft for holding a roll thereon;
- fixing means disposed on a tip end of said roll retainer shaft for fixing said roll to said roll retainer shaft;
- a switching mechanism for selectively holding said roll in a fixed state achieved by said fixing means and releasing said roll from a fixed state achieved by said fixing means;
- and
- a moving mechanism for moving said roll along said roll retainer shaft,
- wherein said moving mechanism is operable to be actuated by a rotating action of a driving mechanism associated with a roll loading shaft toward which said roll is moved.
