Abstract

It is of interest to notify an operator during operation of an agricultural baler that a net roll is going to be depleted and that a last bale or a certain amount of last bales can be wrapped with the remaining wrapping material (e.g. net or film/foil). This is to avoid, that a wrapping process has to be interrupted without finishing the correct wrapping of the bale, or in other words to timely notify the operator that he needs to provide the wrapping device with a new net roll or film roll, respectively. Therefore, a new approach for a “last bale notification” will be described. Nevertheless, an overview of some existing prior art related to wrapping control systems/technology is given as well.

Last Bale Notification

It is of interest to notify an operator during operation of an agricultural baler that a net roll is going to be depleted and that a last bale or a certain amount of last bales can be wrapped with the remaining wrapping material (e.g. net or film/foil). This is to avoid, that a wrapping process has to be interrupted without finishing the correct wrapping of the bale, or in other words to timely notify the operator that he needs to provide the wrapping device with a new net roll or film roll, respectively. Therefore, a new approach for a "last bale notification" will be described. Nevertheless, an overview of some existing prior art related to wrapping control systems/technology is given as well.

It is known to provide net rolls for agricultural round balers with a color mark at the end portion of the rolls, so that an operator can see and detect visually that the end of the roll is approaching. The color mark may be of a red strip painted on the net material in rotational direction of the net roll, so that a wrapped bale placed on the ground after bailing shows a red strip on its outer cylindrical surface. Sometimes the operator does not pay the sufficient intention to the color mark or the color mark on the wrapped bale is not visible as good as to be seen from the cabin of a tractor, particularly during bad daylight conditions.

To facilitate the detection of the end of a net roll and to avoid that the operator misses the visual mark or that he is not able to see it due to bad light conditions it has been already proposed to use reflective and/or luminescent marks, as disclosed in the Canadian Patent CA2579437C "Netting material with reflective or luminescent marker" The abstract of said patent reads that " A netting material (100) includes reflective and/or luminescent markers (110) that make the netting (100) visible in low light or reduced light situations and in certain embodiments also marks the roll end in a manner visible in low light situations. The strip (110) reflects a source of light even from a distance and even at a sharp angle, or alternatively emits light itself. The reflective or luminescent strip (110) may be incorporated into the net (100) in addition to and optionally alongside colored roll-end markers that are easily visible in daylight. As claimed, the netting comprises at least one reflective indicator strip (110,112) located continuously between an end of the netting and a point spaced a predetermined distance from the end, thereby acting as a visual signal to a user that an end of the netting is approaching. Further, a method of wrapping a bale is disclosed and claimed With respect to supplying a baling machine with a roll of knitted netting, wherein said at least one reflective indicator strip (110,112) extends longitudinally continuously from one end of the netting material to a point located at a predetermined distance from said one end, the at least one reflective indicator str...
