Abstract
Method and arrangement for changing the direction of travel of a reel being moved by a incoming conveyor (12), for transfer to the following conveyor, in which method the reel is first brought to a turntable and the direction of travel of the reel is changed by turning the turntable. After turning, the reel is removed to a receiving conveyor. In order for the turntable to be able to turn reels, the width of which is greater than the diameter of the turntable, the reel is lifted on the turntable from the level of the incoming and receiving conveyors, for the duration of the turning.
Claims9
An apparatus for changing the direction of travel of paper, board, or other fibre reels, comprising:
- a turntable rotatable about a vertical axis of rotation, the turntable having an upper surface, a diameter of the upper surface being sufficient to cover a pit in which the turntable operates;
- a conveyor mounted on the turntable and capable of receiving a reel from a bringing conveyor bringing the reel to the turntable, moving the reel on the turntable, and feeding the reel to a receiving conveyor, the conveyor of the turntable having a length less than a greatest width of a reel;
- bearings for rotating the turntable around its axis of rotation;
- means for rotating the turntable on the bearings;
- and
- means for lifting the conveyor of the turntable, without also lifting the upper surface of the turntable, above a level of the bringing and receiving conveyors and for allowing the conveyor of the turntable to be rotated on the bearings while the conveyor of the turntable is in a lifted position.
A method for changing a direction of travel of a reel transported by a bringing conveyor comprising:
- bringing the reel to a conveyor of a turntable the turntable having an upper surface, a diameter of the upper surface being sufficient to cover a pit in which the turntable operates;
- changing the direction of travel of the reel by rotating the turntable;
- removing the reel to a receiving conveyor;
- and
- raising the conveyor of the turntable bearing the reel from a level at which the reel is brought to and received by the turntable for the duration of the rotating of the turntable, the upper surface of the turntable not being raised when the conveyor of the turntable is raised.
