Abstract
A wrapping device and a web supplying method are used on board of an agricultural harvester. A supply reel with wrapping material is held between two parts of an unrolling station. A web moving member moves a web taken from this supply reel away from the unrolling station. For replacing the supply reel with a further supply reel, the further supply reel is placed on at least one supporting roller. The or every supporting roller is stationary and is positioned angularly below the unrolling station and between two unrolling station parts. The further supply reel on the supporting roller is shifted in a shifting direction towards an unrolling station part.
Claims19
A wrapping device for use on an agricultural harvester, wherein the wrapping device comprises:
- an unrolling station comprising a receiving unrolling station part and a further unrolling station part;
- a web moving member;
- and
- a loading device with at least one supporting roller, wherein the unrolling station is arranged to:
- be operated in a holding mode in which the unrolling station holds a supply reel with wrapping material between the receiving unrolling station part and the further unrolling station part and enables a rotation of the supply reel around a reel center axis;
- and
- be transferred into a releasing mode in which the receiving unrolling station part and the further unrolling station part release the supply reel and enable a removal of the supply reel,
- wherein the reel center axis is horizontal when the supply reel is held between the receiving unrolling station part and the further unrolling station part,
- wherein the web moving member is arranged to move a web of wrapping material taken from the supply reel held between the receiving unrolling station part and the further unrolling station part,
- wherein the loading device is arranged to carry a further supply reel,
- wherein the at least one supporting roller of the loading device is arranged:
- to carry from below the further supply reel;
- and
- to enable the shift of the further supply reel in a shifting direction towards the receiving part of the unrolling station,
- wherein a respective roller rotating axis of the at least one supporting roller is positioned perpendicular to the shifting direction,
- wherein the at least one supporting roller is positioned angularly below the unrolling station,
- wherein in the holding mode there is a vertical distance between the at least one supporting roller and a supply reel held between the receiving unrolling station part and the further unrolling station part,
- wherein the respective roller rotating axis of at least one supporting roller is mounted in a position or is transferable into a position between the receiving unrolling station part and the further unrolling station part;
- wherein the at least one supporting roller comprises:
- a rotatable roller body;
- and
- a roller axle extending along the roller rotating axis, wherein the roller axle is stationary with respect to the unrolling station, and wherein the roller body is rotatable around the roller axle, and wherein the or each roller body can be shifted with respect to the corresponding roller axle in two opposing directions both being parallel to the roller rotating axis.
