Abstract
A twine tensioner arrangement for a baler including a pair of rollers, each of the rollers being rotatable about a shaft and having circumferential lobes, at least one of the shafts being mounted on a displaceable armature, displacement measurement apparatus to measure the displacement of the displaceable armature and a signalling apparatus to generate a signal if the displacement of the displaceable armature exceeds a predetermined value. This enables monitoring of the tension in a strand of twine entering the twine tensioner arrangement and when the tension exceeds a predetermined value, allows action to be taken to avoid a mistie or damage to the baler components.
Claims3
A combination comprising:
- an agricultural vehicle;
- a baler towed by the agricultural vehicle, wherein the baler comprises:
- a plurality of knotters, each knotter comprising a twine tensioner arrangement comprising a pair of rollers,
- wherein each roller is rotatable about a shaft and comprises circumferential lobes,
- wherein at least one of the shafts is displaceable, and
- a displacement measurement apparatus that generates displacement signals representative of the displacement of the shafts;
- a user terminal;
- a control unit;
- and
- memory in communication with the control unit, wherein the control unit is configured to receive a plurality of signals including the displacement signals from each twine tensioner arrangement, compare the displacement signals against a predetermined set of values stored in the memory to determine whether an error condition exists, and when the error condition exists, to generate and transmit a signal to the user terminal to generate an indication of the error condition.
