The invention relates to a round baler having a bale chamber in which a round bale can be produced, and a wrapping device with which a completely pressed round bale can be wrapped with a first plastic film in the bale chamber, and a feed device for feeding the first plastic film into the bale chamber. The round baler also includes a feed point at which the first plastic film can be fed to the bale chamber, and an ultrasonic sensor which is arranged at the bale chamber. The ultrasonic sensor is arranged at the bale chamber in such a way that with the ultrasonic sensor it is possible to determine whether the first plastic film is present on a surface of the round bale. The invention also relates to a detection method for detecting a first plastic film on a surface of a round bale.

An agricultural baler system includes: a baler frame; a bale chamber at least one of coupled with and formed by the baler frame; a control system operatively coupled with the baler frame, the control system including: at least one first sensor configured for: detecting at least one first operative condition associated with a baling operation; outputting at least one first operative condition signal corresponding to the at least one first operative condition; a controller system operatively coupled with the at least one first sensor and configured for: receiving the at least one first operative condition signal; determining at least one operative parameter based at least in part on the at least one first operative condition signal, the at least one first operative parameter being associated with a bale of a crop material one of stalling and being about to stall in the bale chamber of a baler.

An accumulator contents detection system for a harvester includes an accumulator, a plurality of metering rollers, and at least one sensor. The accumulator accumulates crop material. The plurality of metering rollers receives crop material from the accumulator. The plurality of metering rollers includes a drive metering roller. The at least one sensor detects a load transmitted to the drive metering roller.

A bale wrapper apparatus includes a table for supporting the bale and rotating the bale about a first axis; a film dispenser including a film holder and a pre-stretcher unit; a drive device for driving relative rotation between the table and the film dispenser about a second axis that is substantially perpendicular to the first axis, and a control unit that controls the pre-stretcher unit. The control unit is configured to control the pre-stretcher unit such that during rotation of the bale, the amount of pre-stretching applied to the film alternates between a first elongation level and a second elongation level. The first elongation level is greater than the second elongation level, such that a part of the film that is pre-stretched at the second elongation level is positioned on a corner of the bale, and a part of the film that is pre-stretched at the first elongation level is positioned on an end face or a side surface of the bale.

A wrapping system includes: a material roll configured to hold a roll of wrapping material; a knife assembly comprising a movable knife that is configured to cut wrapping material that comes off the material roll; a sensor associated with the material roll and configured to output a drawn material signal; and a controller. The controller is configured to: receive the drawn material signal; determine a length of wrapping material that is drawn from the material roll; output a cut signal to the knife assembly when the drawn length of wrapping material reaches a defined length; determine a length of wrapping material that is drawn from the material roll after outputting the cut signal; and output an excessive wrap signal when the length of wrapping material drawn after outputting the cut signal exceeds a threshold length.

A baler implement includes a print system selectively configurable to print a plurality of available alpha-numeric characters on the bale. A marker controller is operable to receive data from a sensor related to a characteristic of the bale and then select a desired alpha-numeric character from the available alpha-numeric characters based on the data from the sensor. The marker controller may then configure the print system to select the desired alpha-numeric character, and actuate the print system to imprint the desired alpha-numeric character onto the bale, thereby marking the bale with the desired alpha-numeric character to communicate the characteristic of the bale.

A wrapping apparatus and A wrapping method are provide to wrap an object in a chamber into a web of wrapping material. The web is moved from a reservoir outside of the chamber. A tag applicator applies a tag on the web in an application position which is between a wrapping material reservoir and a wrapping material inlet. A tag reader monitors whether or not a tag is conveyed in the chamber along the tag reader. If no tag is detected, an alert is generated that the object is not properly wrapped.

A bale identification assembly for use with an agricultural baler (18) includes a first supply roll mounted on the baler providing a binding material (52) used by the knotter system to bind the formed bale, the binding material (52) on the first supply roll comprising identification tags (62) at spaced intervals along the binding material. The bale identification assembly includes a second supply roll mounted on the baler (18) providing a binding material without identification tags, wherein the knotter system combines the binding material with identification tags (62) from the first supply roll with the binding material without identification tags from the second supply roll to bind the formed bale. The bale identification assembly includes a read module with one or more antennas configured to transmit interrogator signals and also receive authentication replies from the identification tags (62).

A bale identification assembly includes binding material used by a knotter system to bind a formed bale, the binding material including identification tags at spaced intervals along the binding material. A read module transmits interrogator signals and also receives authentication replies from the identification tags. A position sensor is used to predict passage of identification tags through the knotter mechanism and a bale length sensor provides a signal representing bale length. A controller receives signals from the bale length sensor and the position sensor and generates a signal to alter the length of the bale by causing an additional flake to be added to the bale by the plunger or the bale to be finished with fewer flakes to prevent the knotter system from tying a knot in the binding material such that the identification tag is positioned in a portion of the binding material used to form the knot.
