Abstract

The present disclosure relates to a round baler (10) including a baling chamber (12) for forming a bale (26) and a first wrapping mechanism (32) mounted to the baling chamber (12). The first wrapping mechanism (32) includes a feed system that feeds the wrap material (30a) into the baling chamber (12). The round baler (10) further comprises a second wrapping mechanism (34) mounted to the baling chamber (12) which includes a feed system that feeds the wrap material (30b) into the baling chamber (12). Further, the round baler (10) includes an inlet (40) wherein wrap material (30a) from the first wrapping mechanism (32) and wrap material (30b) from the second wrapping mechanism (34) enter the baling chamber (12). The first wrapping mechanism (32) and second wrapping mechanism (34) are configured to be operated independently.

First claim

What is claimed is:

1. A round baler comprising:
a baling chamber for forming a bale;
a first wrapping mechanism mounted to the baling chamber, the first wrapping mechanism including a mounting assembly for removably mounting a roll of wrap material and for feeding the wrap material into the bale chamber;
a first actuator attached to the first wrapping mechanism having three positions, a first position wherein the actuator moves the wrap material into a starting feed position, a second position wherein the wrap material is positioned in a feeding position, a third position wherein the actuator moves the wrap material into a cutting position wherein the wrap material contacts a cutting device;
a second wrapping mechanism mounted to the baling chamber, the second wrapping mechanism including a mounting assembly for removably mounting a roll of wrap material and for feeding the wrap material into the bale chamber;
a second actuator attached to the second wrapping mechanism having three positions, a first position wherein the actuator moves the wrap material into a starting feed position, a second position wherein the wrap material is positioned in a feeding position, a third position wherein the actuator moves the wrap material into a cutting position wherein the wrap material contacts a cutting device;
an inlet wherein wrap material from the first wrapping mechanism and wrap material from the second wrapping mechanism enter the baling chamber; and
a controller for controlling a wrapping cycle, wherein the controller is adapted to control the first wrapping mechanism and the second wrapping mechanism so that feeding from both wrapping mechanisms may be sequenced, wherein the controller has a first mode that only operates the feeding and wrapping of one wrapping mechanism during the wrapping cycle, a second mode that operates the feeding and wrapping of the two wrapping mechanisms at separate times during the wrapping cycle, a third mode that operates the feeding of the two wrapping mechanisms separately but the wrapping of the two wrapping mechanisms concurrently during the wrapping cycle, a fourth mode that operates the feeding and wrapping of the two wrapping mechanisms concurrently during the wrapping cycle.

2. The round bale of claim 1 , wherein the inlet is a single inlet in which the wrap material of the first wrapping mechanism and the wrap material of the second wrapping mechanism enter the baling chamber.

3. The round bale of claim 1 , wherein the first wrapping mechanism comprises a first cutting device for cutting the wrap material of the first wrapping mechanism and the second wrapping mechanism comprises a second cutting device for cutting the wrap material of the second wrapping mechanism.

4. The round baler of claim 3 , wherein the first cutting device is a knife and the second cutting device is a knife.

5. The round baler of claim 1 , wherein the first wrapping mechanism comprises a brake for applying force to the roll of wrap material of the first wrapping mechanism to provide for controlled rotation of the roll and the second wrapping mechanism comprises a brake for applying force to the roll of wrap material of the second wrapping mechanism to provide for controlled rotation of the roll.

6. The round baler of claim 1 , further comprising a first sensor in communication with the controller, the first sensor being configured to measure a value representative of the amount of wrap material dispensed from the first wrapping mechanism and a second sensor in communication with the controller, the second sensor being configured to measure a value representative of the amount of wrap material dispensed from the second wrapping mechanism.

7. The round baler of claim 1 , further comprising first and second rotational sensors in communication with the controller, the first rotational sensor being configured to sense the rotation of the roll of first wrap material and the second rotational sensor being configured to sense the rotation of the roll of second wrap material.

8. The round baler of claim 1 , wherein the baling chamber includes a plurality of baling forming belts rotatably disposed therein, and wherein the first wrapping mechanism is adapted to apply wrap material of the first wrapping mechanism to a first location on the bale forming belts and the second wrapping mechanism is adapted to apply wrap material of the second wrapping mechanism to a second location on the bale forming belts.

9. A round baler comprising:
a baling chamber for forming a bale;
a first wrapping mechanism mounted to the baling chamber, the first wrapping mechanism including a mounting assembly for removably mounting a roll of wrap material and for feeding the wrap material into the bale chamber;
a first actuator attached to the first wrapping mechanism having three positions, a first position wherein the actuator moves the wrap material into a starting feed position, a second position wherein the wrap material is positioned in a feeding position, a third position wherein the actuator moves the wrap material into a cutting position wherein the wrap material contacts a cutting device;
a second wrapping mechanism mounted to the baling chamber, the second wrapping mechanism including a mounting assembly for removably mounting a roll of wrap material and for feeding the wrap material into the bale chamber;
a second actuator attached to the second wrapping mechanism having three positions, a first position wherein the actuator moves the wrap material into a starting feed position, a second position wherein the wrap material is positioned in a feeding position, a third position wherein the actuator moves the wrap material into a cutting position wherein the wrap material contacts a cutting device;
an inlet wherein wrap material from the first wrapping mechanism and wrap material from the second wrapping mechanism enter the baling chamber;
a controller for controlling a wrapping cycle, wherein the controller is adapted to control the first wrapping mechanism and the second wrapping mechanism so that feeding from both wrapping mechanisms may be sequenced;
first and second rotational sensors in communication with the controller, the first rotational sensor being configured to sense the rotation of a first roll of wrap material and the second rotational sensor being configured to sense the rotation of a second roll of wrap material;
wherein the first wrapping mechanism includes a first spreader roller for spreading out the wrap material from a first roll of wrap material before the wrap material reaches the inlet and the second wrapping mechanism includes a second spreader roller for spreading out the wrap material from a second roll of wrap material before the wrap material reaches the inlet, wherein the first rotational sensor is positioned to measure the rotational speed of the first spreader roller and the second rotational sensor is positioned to measure the rotational speed of the second spreader roller.

10. The round baler of claim 9 , wherein the controller is configured to not consider the speed of the first spreader roller measured by the first rotational sensor and the speed of the second spreader roller measured by the second rotational sensor unless the measured speeds of the first and second rotational sensors are greater than a predetermined speed.

11. The round bale of claim 9 , wherein the inlet is a single inlet in which the wrap material of the first wrapping mechanism and the wrap material of the second wrapping mechanism enter the baling chamber.

12. The round bale of claim 9 , further comprising:
a first cutting device for cutting the wrap material of the first wrapping mechani
