Abstract
Abstract An automatic control device for controlling the placement of wrap material on a bale within a round baler. A pair of twine guide tubes are actuated for movement by an actuator which is energized by a controller for controlling a twine wrapping operation. Separate twine strands are fed to each of the twine guide tubes and the quantity of twine fed through the guide tubes is monitored by sensor pulleys which send a pulsed signal to the controller. The controller controls the location of the twine guide tubes in response to the sensed signal from the sensing pulleys whereby a predetermined quantity of twine is placed at predetermined locations along the bale.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
89 words
An apparatus for forming and wrapping bales, said apparatus comprising: a chamber for receiving crop material to form a bale, wrap guide means for guiding wrap material onto a bale in said chamber, monitoring means for monitoring the distribution of said wrap material onto said bale, control means for controlling the position of said wrap guide means in response to the monitored distribution of said wrap material, and wherein said monitoring means comprises sensing means for measuring the quantity of wrap material as it is dispensed onto said bale.
Claim 2
Independent Claim
89 words
An apparatus for forming and wrapping bales, said apparatus comprising: a chamber for receiving crop material to form a bale, wrap guide means for guiding wrap material onto a bale in said chamber, monitoring means for monitoring the distribution of said wrap material onto said bale, control means for controlling the position of said wrap guide means in response to the monitored distribution of said wrap material, and wherein said monitoring means comprises sensing means for measuring the quantity of wrap material as it is dispensed onto said bale.
Claim 3
Dependent Claim
23 words
The apparatus as in claim 1 wherein said wrap guide means is positionable to a plurality of discrete predetermined positions along said bale.
Claim 4
Dependent Claim
29 words
The apparatus as in claim 2 wherein said wrap guide means dwells at each of said discrete positions while a predetermined quantity of material is distributed onto said bale.
Claim 5
Dependent Claim
48 words
The apparatus as in claim 1 wherein said wrap guide means is movable from a first position to a second position on said bale and said control means is programmable to wrap a bale with an operator selected quantity of material from said first to said second position.
Claim 6
Dependent Claim
35 words
The apparatus as in claim 4 wherein said wrap material is twine for wrapping a round bale and said operator selected quantity of material corresponds to a twine spacing between wraps selected by an operator.
Claim 7
Dependent Claim
31 words
The apparatus as in claim 1 wherein said control means positions said wrap guide means at different positions along said bale in response to the measured quantity of wrap material dispensed.
Claim 8
Independent Claim
82 words
An apparatus for forming and wrapping round bales with twine, said apparatus comprising: a chamber for receiving crop material to form a bale, a twine tube assembly for guiding twine onto a bale in said chamber, a twine feed sensor for monitoring the quantity of twine as it is fed onto said bale, and a controller for receiving a signal from said twine feed sensor and for controlling a predetermined sequence of operations for wrapping said bale in response to said signal.
Claim 9
Independent Claim
82 words
An apparatus for forming and wrapping round bales with twine, said apparatus comprising: a chamber for receiving crop material to form a bale, a twine tube assembly for guiding twine onto a bale in said chamber, a twine feed sensor for monitoring the quantity of twine as it is fed onto said bale, and a controller for receiving a signal from said twine feed sensor and for controlling a predetermined sequence of operations for wrapping said bale in response to said signal.
Claim 10
Dependent Claim
54 words
The apparatus as in claim 7 wherein said twine tube assembly is mounted for rotational movement and includes an actuator for locating an end of said tube assembly at a plurality of predetermined positions whereby said twine is guided into contact with said bale at different locations along a longitudinal axis of said bale.
Claim 11
Dependent Claim
38 words
The apparatus as in claim 8 wherein said actuator causes said tube assembly to dwell at each of said predetermined positions to permit a measured quantity of said twine to be dispensed at each of said predetermined positions.
Claim 12
Dependent Claim
25 words
The apparatus as in claim 9 wherein said measured quantity of twine is dispensed independently of a rotational speed for said bale within said chamber.
Claim 13
Dependent Claim
28 words
The apparatus as in claim 7 wherein said twine feed sensor comprises a twine sensor wheel and a sensor for sensing the number of rotations of said wheel.
Claim 14
Dependent Claim
62 words
The apparatus as in claim 7 wherein said twine tube assembly guides said twine from an initial position to an end position on said bale and said controller includes means for an operator to select the spacing between adjacent wraps of twine applied to said bale as said twine is applied to said bale from said initial position to said end position.
Claim 15
Dependent Claim
36 words
The apparatus as in claim 7 wherein said controller includes an indicator panel for indicating to an operator the number of wraps applied to said bale in response to said signal from said twine feed sensor.
Claim 16
Dependent Claim
27 words
The apparatus as in claim 7 wherein said controller includes an indicator panel for indicating to an operator the twine spacing between wraps applied to said bale.
Claim 17
Dependent Claim
36 words
The apparatus as in claim 7 wherein said twine tube assembly comprises two twine tubes mounted for pivotal movement to feed two strands of twine, said twine tubes being connected to each other for simultaneous movement.
