Displaceable wrapping material supply unit for baling apparatus
A wrapping material supply apparatus for supplying wrapping material to a wrapper inlet of a baling chamber, in which a bale is to be wrapped. The wrapping material supply apparatus includes a wrapping material supply unit displaceable between a baling position and a wrapping position by a first actuator, and a cutting apparatus located at a lower end of the wrapping material supply apparatus. Movement of the wrapping material supply apparatus between the baling position and the wrapping position is independent of the movement of the cutting apparatus.
1 . A wrapping material supply apparatus for supplying wrapping material to a wrapper inlet of a baling chamber, in which baling chamber a bale is to be wrapped with the wrapping material, comprising:
a wrapping material supply unit comprising a channel between a planar element and an endless belt, wherein the wrapping material supply unit is displaceable between a baling position and a wrapping position by a first actuator; and
a cutting apparatus located at a lower end of the wrapping material supply apparatus.
2 . The wrapping material supply apparatus of claim 1 , wherein the cutting apparatus is displaceable about the lower end of the wrapping material supply apparatus.
3 . The wrapping material supply apparatus of claim 1 , wherein the cutting apparatus comprises a pivoting frame comprising a cutting element moveable between a first position allowing free passage of wrapping material through the wrapping supply apparatus and a second position in which the cutting element severs wrapping material passing through the wrapping supply apparatus.
4 . The wrapping material supply apparatus of claim 3 , further comprising a second actuator to displace the pivoting frame between the first and second positions.
5 . A baler comprising the wrapping material supply apparatus of claim 1 .
6 . A baling arrangement comprising the baler of claim 5 and an agricultural vehicle.
7 . The baling arrangement of claim 6 , further comprising a bale size sensor, a bale wrapping sensor and an electronic control unit.
8 . The baling arrangement of claim 1 , wherein the endless belt is driven at a first end about a first roller and a second end of the endless belt has a second roller, and the planar element comprises a central planar portion, wherein the central planar portion extends alongside and parallel to a portion of the endless belt between the first and second rollers.
9 . The baling arrangement of claim 8 , wherein the planer element comprises a guidance portion at an upper end and a lower end of the planer element, wherein each guidance portion is angled away from the central planar portion and the and the first and second rollers.
10 . A wrapping material supply apparatus for supplying wrapping material to a wrapper inlet of a baling chamber, in which baling chamber a bale is to be wrapped with the wrapping material, comprising:
a wrapping material supply unit comprising a channel between a planar element and an endless belt, wherein the wrapping material supply unit is displaceable between a baling position and a wrapping position by a first actuator;
a cutting apparatus located at a lower end of the wrapping material supply apparatus, wherein the cutting apparatus comprises a pivoting frame comprising a cutting element moveable between a first position allowing free passage of wrapping material through the wrapping supply apparatus and a second position in which the cutting element severs wrapping material passing through the wrapping supply apparatus; and
a second actuator to displace the pivoting frame between the first and second positions, wherein the second actuator is operated independently of the first actuator.
11 . The baling arrangement of claim 10 , wherein the endless belt is driven at a first end about a first roller and a second end of the endless belt has a second roller, and the planar element comprises a central planar portion, wherein the central planar portion extends alongside and parallel to a portion of the endless belt between the first and second rollers.
12 . The baling arrangement of claim 11 , wherein the planer element comprises a guidance portion at an upper end and a lower end of the planer element, wherein each guidance portion is angled away from the central planar portion and the and the first and second rollers.
