Abstract

A method of monitoring a status of a supply of wrap material of a baler implement includes receiving a supply roll length input when a new supply roll of wrap material is loaded into a wrap system of the baler implement. A respective length of the wrap material used to wrap each bale since receiving the supply roll length input is determined and summed together to define a total current used wrap value. The total current used wrap value is subtracted from the total longitudinal length to define a current remaining length of the wrap material. A notification signal is communicated to a communicator to indicate to an operator the current remaining length of the wrap material on the supply roll of the wrap material.

First claim

The invention claimed is:

1 . A method of operating a baler implement operable to form a bale having a cylindrical shape and wrap the bale with a wrap material, the method comprising:
receiving a supply roll length input with a baler controller, wherein the supply roll length input includes a total longitudinal length of the wrap material included on a full supply roll of the wrap material; sensing data related to the respective length of the wrap material used to wrap each bale, with a sensor positioned on the baler implement, wherein sensing data related to the respective length of the wrap material used to wrap each bale includes sensing a dispensing speed of the wrap material during a bale wrap process and sensing a time period during which the wrap material is dispensed during the bale wrap process; determining, with the baler controller, a respective length of the wrap material used to wrap each bale since receiving the supply roll length input, wherein determining the respective length of the wrap material used to wrap each bale includes multiplying the dispensing speed by the time period to calculate the respective length of the wrap material used to wrap each bale; summing, with the baler controller, all of the respective lengths of the wrap material used to wrap each bale since receiving the supply roll length input, to define a total current used wrap value; subtracting, with the baler controller, the total current used wrap value from the total longitudinal length to define a current remaining length of the wrap material; d communicating a notification signal to a communicator with the baler controller, wherein the notification signal indicates the current remaining length of the wrap material on the supply roll of the wrap material.

2 . The method set forth in claim 1 , further comprising communicating the sensed data related to the respective length of the wrap material used to wrap each bale from the sensor to the baler controller, whereby the baler controller uses the sensed data to determine the respective length of the wrap material used to wrap each bale.

3 . The method set forth in claim 1 , wherein sensing the dispensing speed of the wrap material during the bale wrap process includes sensing a linear speed of the wrap material.

4 . The method set forth in claim 1 , wherein sensing the dispensing speed of the wrap material during the bale wrap process includes sensing a rotational speed of a supply roller engaged with the wrap material during the bale wrap process.

5 . The method set forth in claim 1 , further comprising automatically detecting installation of a supply roll of the wrap material into a wrap system of the baler implement.

6 . The method set forth in claim 5 , further comprising automatically prompting an operator to enter the supply roll length input into the baler controller upon detecting installation of the supply roll of the wrap material into the wrap system of the baler implement.

7 . The method set forth in claim 5 , further comprising automatically scanning a data device disposed on the supply roll of the wrap material, with a reader disposed on the baler implement, to detect data providing the supply roll length input upon detecting installation of the supply roll of the wrap material into the wrap system of the baler implement.

8 . The method set forth in claim 7 , further comprising automatically communicating the detected data providing the supply roll length input from the reader to the baler controller.

9 . The method set forth in claim 1 , wherein communicating the notification signal to the communicator includes displaying a visual indication of the current remaining length of the wrap material on the supply roll of the wrap material.

10 . A baler implement comprising:
a baling chamber operable to form a material into a bale having a cylindrical shape; a wrap system operable to supply a wrap material from a supply roll of the wrap material into the baling chamber to wrap the bale; a baler controller including a processor and a memory having a wrap monitoring algorithm stored thereon, wherein the processor is operable to execute the wrap monitoring algorithm to:
receive a supply roll length input defining a total longitudinal length of the wrap material included on a full supply roll of the wrap material;
sense data related to the respective length of the wrap material used to wrap each bale, with a sensor positioned on the baler implement, wherein the data related to the respective length of the wrap material used to wrap each bale includes a dispensing speed of the wrap material during a bale wrap process, and a time period during which the wrap material is dispensed during the bale wrap process;
determine a respective length of the wrap material used to wrap each bale by multiplying the dispensing speed by the time period to calculate the respective length of the wrap material used to wrap each bale;
sum all of the respective lengths of the wrap material used to wrap each bale since receiving the supply roll length input since receiving the supply roll length input, to define a total current used wrap value;
subtract the total current used wrap value from the total longitudinal length to define a current remaining length of the wrap material; and
communicate a notification signal to a communicator, wherein the notification signal indicates the current remaining length of the wrap material on the supply roll of the wrap material.

11 . The baler implement set forth in claim 10 , wherein the processor is operable to execute the wrap monitoring algorithm to automatically detect installation of a supply roll of the wrap material into the wrap system.

12 . The baler implement set forth in claim 11 , wherein the processor is operable to execute the wrap monitoring algorithm to automatically prompt an operator to enter the supply roll length input upon detecting installation of the supply roll of the wrap material into the wrap system of the baler implement.

13 . The baler implement set forth in claim 11 , further comprising a reader positioned to detect a data device on the supply roll of the wrap material in the wrap system, and wherein the processor is operable to execute the wrap monitoring algorithm to automatically scan the data device disposed on the supply roll of the wrap material, with the reader, to detect data providing the supply roll length input upon detecting installation of the supply roll of the wrap material into the wrap system.

14 . The baler implement set forth in claim 11 , wherein the communicator includes a display device, and wherein the processor is operable to communicate the notification signal to the display device to present a visual indication of the current remaining length of the wrap material on the supply roll of the wrap material on the display device.
