1. A film fitting system which fits a tubular film on a fitting target, comprising:
a fitting device which fits, at a predefined fitting position, the tubular film on the fitting target which is transported; and a transporting device which receives the fitting target at a predefined supplying position, and then transports the fitting target via the fitting position to a sending position where the fitting target is discharged from the transporting device, wherein the transporting device comprises: a plurality of mounts which are moved in a state where the fitting target is placed thereon, to move the fitting target from the supplying position via the fitting position to the sending position; positioning members which are provided, one for each mount and linked with the corresponding mount and which are moved with the corresponding mount and which position the fitting target with respect to the mount by pushing the positioning member against and contacting the fitting target; and a moving device which moves the positioning member to a reference position where the fitting target can be positioned at the supplying position, and moves the positioning member to a retracted position where the positioning member is separated from the fitting target at the fitting position, wherein the moving device comprises:
a first elastic element which biases the positioning member in a direction toward the reference position;a stopping member, which directly or indirectly through a connecting frame contacts the positioning member, to stop the positioning member at the reference position;a movable lever which can oscillate between a position in which the movable lever contacts the connecting frame and a position where the moveable lever does not contact the connecting frame;a pressing member which causes the movable lever to press the positioning member through the connecting frame against the biasing force of the first elastic element and in a direction toward the retracted position; anda second elastic element which biases the movable lever in a direction to release the pressing of the movable lever against the positioning member through the connecting frame when the pressing by the pressing member is released,wherein the pressing member presses the movable lever at the fitting position, and releases the pressing of the movable lever positioned at the supplying position. |
