    Descriptive Report of the Patent of Invention for CONTINUOUS BALER OF ROUND BALES.
    The present invention relates to continuous round balers.
    Background
    Conventional round balers receive the harvest material and take it into the form of compacted bales in a bale forming chamber. In general, a round baler comprises three main operating cycles: a bale forming cycle, a bale winding cycle, and a bale ejection cycle. Typically, a round baler is driven and towed by means of a tractor. A harvest picker picks up the material on the ground and takes it to the baler-forming straps of the baler to form a bale.
    Once the bale-forming cycle is complete and the bale is fully formed, the towing vehicle can stop and a bale winding cycle can begin. For example, once a bale reaches a desired size and / or shape, the operator stops the forward movement and stops feeding material from the harvest to the baler, so that a baler can perform the wrapping operations. When the forward movement of the baler is stopped, mesh or wrapping string is wrapped around the bale using an automated mechanism associated with the baling chamber.
    Once wrapping is complete, a bale ejection cycle can be started in which the bale chamber is opened, typically by lifting a rear hatch, and the wrapped bale falls or is pushed out of the bale chamber. After ejection, the bale-forming cycle is restarted for a new bale and once again the operator supplies harvest material to the baler and moves the baler across the field.

    Description of Exemplary Embodiments 25 General Aspect
    In an exemplary embodiment, the continuous baler receives harvest material from a source of harvest material and packs the harvest material in the form of bales. The term continuous refers to the receipt of the harvest material by the continuous baler when the baler forms the bales. For example, the baler can be towed across a field without stopping as the harvest material is picked up and the baler continues through its cycles
    3/28 operational. This eliminates the stopping of the baler movement through the field and the stop of the reception of the harvest material that occurs according to traditional methods when the baler performs several operations in which it does not receive the harvest material, such as during a burden. The term harvest material is intended to include grain and other material other than grain (MOG), such as waste from a harvester. For example, the continuous baler can be used to bundle hay or biomass material, such as corncobs or the like. This arrangement provides several advantages over prior art systems, including the ability to continuously move the baler across the field and collect harvest material during the various balers' operational cycles. An adjustable harvest material conveyor system can be used to accumulate harvest material and provide harvest material for the baler according to various balers operating cycles.
    In an exemplary embodiment, an adjustable speed conveyor system comprises an adjustable harvest material conveyor for receiving harvest material from a source of harvest material and providing the harvest material for a baler, and a controller for manipulating speed adjustable speed conveyor. In an exemplary embodiment, the harvest material source is a reaper that provides harvest material for the adjustable harvest material carrier. A user interface can also be provided to receive operating instructions from a continuous baler operator and to control certain functions of the baler and the adjustable harvest material conveyor according to the operating instructions. For example, a controller can vary the speed of the conveyor according to predetermined schemes provided by the operator via the user interface. In an exemplary embodiment, the user interface can be used to drive the conveyor of adjustable harvest material according to a scheme in which the speed of the conveyor is changed according to
    4/28 different balers operating cycles. For example, the conveyor can be stopped, started, accelerated, delayed and / or reversed according to the different operating cycles of the baler.
    In an exemplary embodiment, the adjustable harvest material conveyor may comprise one or more conveyor belts rotatably mounted on rollers, such as a drive roller and an intermediate roller. The drive roller can be moved by means of a hydraulic motor that can be manipulated by the controller and several solenoids and flow control valves to vary the speed and direction of the drive roller and, thus, the speed and direction of movement of the conveyor belts and thereby manipulate the supply of harvest material that is provided to the carrier from the source of harvest material, to the baler. A front or feed end of the conveyor can be positioned adjacent to the harvest material source to receive the harvest material. A rear or outlet end can be positioned adjacent to a baler inlet such that the harvest material received from the source of harvest material can be transported via the conveyor from the feed end into the baler for en20 uniform. In an exemplary embodiment, the feed end is positioned to receive harvest material from a harvester outlet and the conveyor outlet end is positioned adjacent to a baler feeder. Although exemplary embodiments are discussed in the context of a conveyor belt, one skilled in the art will recognize that other conveyor arrangements, such as an auger conveyor or chain conveyor as are known in the art, and the term conveyor may be used. it is intended to incorporate these alternative provisions.
    An exemplary method for providing harvest material for a baler comprises: continuously receiving harvest material on an adjustable speed harvest material carrier configured to provide the harvest material for a baler;
    5/28 determine a baler operating cycle; and manipulating the movement of the conveyor according to the operation of the baler to provide the harvest material for the baler. Another exemplary method of providing harvest material for a baler comprises: continuously receiving harvest material in a harvest material carrier from a source of harvest material; moving the harvest material carrier to transport the harvest material to a baler during a baler bale formation cycle; stop the conveyor during a baler wrap cycle; and moving the harvest material conveyor after the bale is ejected from the baler. According to exemplary embodiments, the conveyor can be moved under a first speed to transport the harvest material to the baler during the bale-forming cycle of the baler until the bale reaches a first bale dimension; and moving the conveyor under a second speed during the bale-forming cycle of the baler to transport the harvest material received from the source of harvest material to the baler until the bale reaches a second bale dimension.
    An exemplary method for baling harvest material comprises: continuously providing harvest material for a harvest material carrier, with the harvest material carrier configured to provide the harvest material for the baler; determine a baler operating cycle; and manipulate the movement of the harvest material conveyor in response to the baler operating cycle. Another exemplary method for baling harvesting material comprises: continuously receiving harvesting material on a harvesting material carrier from a source of harvesting material; move with the harvest material conveyor to provide the harvest material for the baler; receiving the harvest material from the harvest material carrier in the baler and forming a burden; eject the bale from the baler; and restart the conveyor to provide harvest material for the baler. Shall be
    6/28 noted that harvest material can be provided continuously to the conveyor during the various operating cycles of the baler, when the harvest material is then provided to the baler via the conveyor, thus allowing the baler and the equipment that moves the baler. balers move continuously over the field and the harvest material accumulates on the conveyor. In the exemplary method, the harvest material conveyor can be driven under a first speed to provide the harvest material for the baler until the baler forms a first dimension bale in the baler; and after the bale reaches the first dimension, move the conveyor under the second speed.
    Detailed Description
    As required, exemplary embodiments of the present invention are exposed in this context. The various embodiments are understood to be non-limiting examples of the various ways of implementing the invention and it will be understood that the invention can be realized in alternative forms. The present invention will be described more fully below with reference to the accompanying drawings in which equal numbers represent similar elements throughout the various figures, and in which exemplary embodiments are illustrated. Figures are not necessarily to scale and some aspects may be exaggerated or minimized to show details of particular elements, although related elements may have been eliminated to prevent new aspects from being confused. The specific structural and functional details exposed in this context should not be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching the person skilled in the art to employ the present invention in a diversified manner.
    Turning now to the figures, figure 1 shows a diagram of a continuous baler 10 that includes a baler 12 and an adjustable conveyor 14 for receiving harvest material 16 from a source of harvest material 18, and providing harvest material 16 to the
    7/28 baler 12 (as illustrated by the small arrow) for forming a bale 20. A vehicle 22, such as a tractor or combination, can be used to tow baler 12 across a field, as indicated by the big arrow in figure 1.
    As shown in figure 2, the adjustable conveyor 14 can be incorporated as part of the round baler 12, such as the 5500 and 900 series round balers manufactured by Agco Corporation including the Hesston 5545, 5556, round balers, 5556A, and 5546; nevertheless, the invention can be incorporated as a part of other types of baling equipment, such as fixed chamber balers, and the like. Other details balers Round baler that can be used with the present invention are described in U.S. Patent Nos. 7,3376,713; 6,477,824; 6,675,561; 4,850,271; and 4,524,867, all of which are incorporated in their entirety in this patent application by reference. As seen in the exemplary embodiment illustrated in Figure 2, the round baler 12 can include a lower drive roller 24 and a starting roller 26. An upper drive roller 28 is provided above the lower drive roller. articulated form inside the baler a belt tensioner arm 30 is provided to which the front belt tension roller 32 and the rear belt tension roller 34 are pivotally mounted. At the top of the front part of the bale chamber, an intermediate roller is provided front upper 36 and a rear upper intermediate roller 38. Following the inside of the baler wall25 clockwise a roller of the rear hatch strap 40, a lower rear hatch roller 44 r and the lower front intermediate roller 46. A bale density arm 48 is pivotally mounted inside the baler and has a density roller and front bale 50 and a rear bale density roller 52, both hingedly mounted on the end end from the bale density arm pivot assembly 48. Near the top of the bale chamber above the bale density rollers is a camera arranged
    8/28 bale roll upper 54. A plurality of bale forming belts 56 (one illustrated in profile) is threaded around each of the rollers identified previously as shown in figure 2. The bale forming belts are stretched by means of the front and rear belt tension rollers 32, 34, mounted on the belt tension arm 30 and the rollers 50, 52 mounted on the bale density arm 48.
    The exemplary baler includes a rear hatch 58 that opens and closes around a pivot point 60. A bale pusher assembly 62 (illustrated schematically) is associated with the rear hatch. The bale pusher assembly includes the bale pusher bar 64 (shown in its starting position) and two hydraulic cylinders (not shown). The bale pusher is used to prevent contact between the rear hatch 58 and the bale when the rear hatch is closing. After the rear hatch rises, hydraulic pressure is applied to the base end of the hydraulic pusher cylinders. The bale pusher 64 moves up and back by pushing the bale out of the rear hatch before the rear hatch is closed. After the rear hatch is closed, the pusher returns to its starting position.
    A baler control system may include a controller 70 positioned on or near the round baler 12 and a user interface 500 (figure 5) preferably positioned on the towing vehicle 22, such as a tractor, harvester, which tows the baler 12. Controller 70 can receive data from a variety of different sensors and in response issue commands to perform various operations on the baler and / or the adjustable conveyor 14. Although controller 70 and user interface 500 are preferred separate components, their functions can also be combined into a single unit positioned either on the baler 12 or on your towing vehicle 22. Baler controller 70 can be used to control the operation of the baler 12, including its various operating cycles, such as bale formation cycles, bale wrapping, and
    9/28 bale ejection, and the adjustable harvest material carrier 14. For example, a bale size sensor 68 (illustrated schematically) can determine the bale size for bale 20 in the bale formation chamber and provide a corresponding signal for controller 70 and user interface 500. Controller 70 can then determine the desired duty cycle for baler 12 and the desired operation of adjustable conveyor 14.
    The bale size sensor 68 can be positioned on the density arm 48 and detect the angular position of the bale density arm 10 and send signals to the electronic control system to indicate the size of the bale during the bale formation cycle. In addition, the baler can include rear hatch keys 80 (illustrated schematically) that detect the position of the rear hatch, whether open or closed, pusher keys 82 (illustrated schematically) that detect the position of the pusher whether it is out or retracted, and lock keys 84 (illustrated schematically) which detect whether the rear hatch is locked. The rear hatch and pusher switches cause signals to be sent to controller 70 thereby indicating the state of the elements to which they are connected.
    In addition to the elements described above, the baler 12 may include a hydraulic pump 88 and a clutch and control electronics assembly, none of which is illustrated in figure 2, but which are necessary for operation of the baler as will be understood by those normally versed in the technique.
    In the exemplary embodiment illustrated in figure 2, the adjustable conveyor 14 for use with the round baler 12 can include the conveyor 90 provided with a plurality of endless belts 92 which are passed around rollers 94, 96 for movement. The top surface 98 of the conveyor belts 92 defines a mobile accumulation and transport surface for receiving and transporting harvest material 16 provided to the conveyor from a source of harvest material to an inlet 198 of the baler 12. The belts
    10/28 conveyors 92 can be arranged in such a way that the conveyor belts 92 extend from a front or rear end 112 which is located adjacent the source of harvesting material to a rear or outlet end 114 adjacent to an entrance 198 of the baler 12.
    The belts 92 can be driven by a drive roller 94 whose rotation results in movement of the belts 92. The drive roller 94 can in turn be driven by a hydraulic motor 120. For example, fluid can be provided to the hi10 hydraulic motor 120 from a hydraulic pump 88 and manipulated by means of solenoids and / or flow control valves to vary the fluid flow to promote the variation of the motor speed 120. The drive roller 94 can be coupled to the motor 120 by means of a chain 130 or other means as are known in the art so that by varying the speed of the motor 120, the rotation of the drive roller 94 and the conveyor belts 92 driven by means of the drive roller 94.
    This arrangement allows the movement of the conveyor belts 92 to be controlled by means of the controller 70. In an exemplary embodiment, the hydraulic pump 88 can be mounted on the baler and driven by a vehicle PTO mechanism 22. Hydraulic lines 140 can extend to a manifold 142 that is mounted on the baler 12 and to be coupled to the solenoid valves and / or flow control valves that react to the command signals sent from a controller 70 to manipulate fluid hydraulic provided for motor 120. In an exemplary embodiment, a connected solenoid valve 150, a disconnected solenoid valve 152, and a flow control valve 154 (all of them schematically illustrated in figure 4) can be coupled in communication with the controller 70 and used to control the hydraulic motor 120 and thus the movement of the conveyor belts 92. The controller 70 t It can also manipulate other components of the baler 12 related to the various operating cycles of the baler. It should be noted that although a single controller 70 is illustrated as controlling both the adjustable conveyor system 14 and the baler operating cycles, multiple controllers may be used to perform the same tasks.
    As discussed in more detail below, conveyor 90 can be manipulated by means of controller 70 according to predetermined schemes programmed by an operator. For example, conveyor 90 can be driven at different speeds in conjunction with the different operating cycles of the baler 12. For example, conveyor belts 92 can be driven under a first speed during a baler bale formation cycle 12 and a second speed or stops during the winding and / or ejection cycles of the baler 12 to allow the harvest material to accumulate on the conveyor belts 92. This allows the continuous movement of the baler 12 through the field as the harvest material 16 can be received continuously from the harvester 22 or other source of harvest material and accumulated on the conveyor 90 during the operating cycles of the baler where the conveyor 90 does not transport 20 harvest material 16 into the baler 12. The accumulated harvest material 16 can then be fed into the baler 12 during an operating cycle appropriate, such as a bale-forming cycle.
    Belts 92 may comprise a plurality of parallel, spaced endless belts wound around rollers 94, 96. Other arrangements may be used, such as a single belt of greater width. In the exemplary embodiments, the belts 92 can be staggered in such a way that all others are wrapped around a lower intermediate roller 86. This arrangement creates gaps between the parts of the belts that extend below the rolls 94, 96 to allow the harvest material 16 that falls in the gap between the conveyor belts 92 passes to the ground.
    12/28
    To couple the adjustable conveyor 90 to the baler, front support sets 188 and rear support sets 190 can be provided (only one of each is shown in figure 2). The support assemblies may include mounting plates 192, 194 that couple the conveyor 90 to the draw lance 200 and the baler 12 and swivelly support the intermediate rollers 96 and drive rollers 94, respectively. One skilled in the art will recognize that other conveyor arrangements can be employed such as an auger conveyor or chain conveyor, as are known in the art.
    Various sensors on the baler 12 can be used by controller 70 to control the operating cycles of baler 12 and the movement of conveyor belts 92 on conveyor 90. For example, controller 70 can orient baler 12 to initiate a bale formation cycle and , if the bale size sensor 68 sends a signal that the bale 20 is smaller than a minimum dimension, then the controller 70 can operate the conveyor belts 92 under a first speed, such as a low speed. If the bale size sensor 68 indicates that the bale 20 is greater than a minimum dimension, but less than a maximum dimension, then controller 70 can operate the conveyor under a second speed, such as a high speed. If the bale size sensor 68 indicates that the bale 20 is greater than a maximum bale dimension, then the controller 70 can stop the conveyor belts 92 and the baler belts 56 and direct the baler 12 to carry out the baling cycles. winding and ejection. When other sensors, such as the rear hatch switch 80, indicate that bale 20 has been ejected from baler 12, then controller 70 can start a new bale formation cycle and restart operation of baler belts 56 and conveyor belts 92.
    Figure 3 shows an exemplary embodiment of a continuous round baler 12 being towed by means of a harvester 22. The harvester 22 is coupled to the baler 12 by means of the drawbar 200 and ejects harvest material 16 processed through the cei13 / 28 conveyor 22 on conveyor belts 92. Conveyor 90 transports harvest material 16 to baler 12.
    Figure 4 is a schematic drawing of an embodiment of an electronic control system 400 of the continuous round baler 12 of figure 2. The system 400 of figure 4 comprises a system box 402 containing a controller 70 and associated electronic components whose construction will be understood by those of ordinary skill in the art, but whose details are not important to the present invention. The arrangement can be comprised of hardware, software, unalterable software or their combination, as will be apparent to those skilled in the art. For example, controller 70 may be a microcontroller capable of receiving data and issuing commands to control the various systems and components according to particular schemes that can be programmed in the microcontroller.
    Schematically illustrated, three harnesses or networks are provided that connect the system box 402 and the controller 70 to the elements controlled by the controller that are distributed around the round baler 12 and the conveyor 90. There is a main harness 406, a harness mesh 410, and a pusher harness 414. Although simple lines are illustrated extending from the system box to the various elements, these lines are intended to represent various connection connections that extend through the harnesses and are connected to the elements indicated.
    Main harness 406 connects system box 402 and controller 70 to different sensors and switches including a string arm sensor 420, a bale size sensor 68, a left string movement key 424, a right string 428, an overmount limit switch 430 and a left rear hatch lock key 434. The bale size sensor 68 sends signals to controller 70 to indicate the size of the bale during the forming cycle. String arm sensor 420 sends signals to controller 70 to indicate the location of the string arm if an arm is being used
    14/28 of string. In a similar way, left and right string movement keys 424, 428 indicate to the controller when the left and right string rolls are spinning and, for this reason, distributing string. The oversize limit switch 430 tells the controller when the bale has exceeded the trigger point for a maximum bale dimension in the chamber. The rear hatch lock switch 434 indicates whether the left rear hatch lock is open or closed. A line 440 is intended to indicate schematically that the left rear hatch key 434 is effectively connected in series with the right rear hatch key 444 (as described below).
    Main harness 406 also connects system box 402 and controller 70 to the different solenoids and valves that activate the flow of hydraulic fluid for the different baler 12 and conveyor 90 systems. These may include the string feed solenoid 450, the string point solenoid 454, the rear hatch rising solenoid 460, the rear hatch descending solenoid 464, the solenoid connecting conveyor 150, the solenoid turning off conveyor 152, a flow control valve 154, pusher solenoid 470, and clutch solenoid 472 and an auxiliary solenoid (not shown). The string feed solenoid 450 drives the string winding mechanism. The point of origin solenoid 454 causes the string arm to return to its point of origin position. The rear hatch lift solenoid 460 drives a hydraulic cylinder that lifts the rear hatch 58. The rear hatch lower solenoid 464 causes the same hydraulic cylinder to close the rear hatch 58. The pusher solenoid 470 drives the hydraulic cylinders to move the pusher out and back. Clutch solenoid 472 engages and disengages the main drive clutch to establish and sustain the drive connection between the tractor's PTO shaft and various baler components 12, such as top augers, the starting roller, and the baler belt drive rollers. The solenoid 150 that connects the conveyor triggers the movement of the conveyor belts 92/28 of the conveyor 90, the solenoid 152 that disconnects the conveyor causes the conveyor belts 92 to stop, and the flow control valve 154 regulates the speed of the belts. conveyors 92 by controlling the flow of hydraulic fluid to the 460 engine. The auxiliary solenoid is available to drive optional equipment.
    Mesh harness 410 connects system box 402 and controller 70 to mesh mean switch 474, mesh count switch 476, mesh feed solenoid 478, mesh cutter 480, and solenoid from 482 mesh origin point. The mesh winding mechanism is optional and can thus appear or not in any given unit. The mesh mean switch 474 provides position feedback for controller 70 to stop the mesh distribution roller at the correct winding location. The mesh count switch 476 allows controller 70 to assess the amount of mesh utilization and indicate that the mesh is being applied. The 478 mesh feed solenoid causes the mesh to be fed into the bale chamber during the winding cycle. The point-of-origin mesh solenoid 482 activates a hydraulic cylinder that returns the mesh winding mechanism to its original position, at which point a mechanical break will cut the mesh and close the mesh cutter 480, signaling thus the end of the loop winding process for controller 70.
    The pusher harness 414 connects the system box 402 and the controller 70 to the different keys, including the rear hatch up switch 484, the right rear hatch lock switch 444, the rear hatch down key 486, the key pusher exit switch 488, and the pusher return switch to home position 490. The rear hatch raise switch 484 signals the controller when the rear hatch 58 is in the raised position. The right rear hatch lock switch 444, connected in series with the left rear hatch lock switch 434, signals the controller 70 when the rear hatch 58 is locked. Because of the serial connection between these two keys,
    16/28 no signal is sent unless both are closed. The rear hatch lowering key 486 signals the controller 70 when the rear hatch 58 is in its lowered position and that the pusher solenoid 470 should be de-energized. The outside pusher switch 488 signals the controller when the pusher is in its outside position and the rear hatch lowering solenoid 464 must be excited. The pusher home position switch 490 signals controller 70 when the pusher is in its home position.
    Figure 5 is a plan view of a user interface 500 in the form of a control console 500 provided at the operator station, such as in the cab of the towing vehicle, such as a harvester 22 that tows the baler 12 through the field and provides harvest material 16 for the baler 12, which is accessible by an operator when operating the round baler 12. The control console 500 can be configured with controls to provide the operator with different levels of control over the baler 12 and adjustable conveyor 14. For example, the operator can be equipped with full manual control mode of the round baler, semi-automatic control mode, or automatic control mode. In full manual control mode, the operator starts each main step in the baling process. In semiautomatic mode, the operator will have less interaction and will control fewer tasks. In full automatic control mode, the baler 12 and the adjustable conveyor 14 can operate continuously without any additional contribution from the operator.
    The exemplary embodiment of the control console 500 of figure 5 includes a power on / off button 502, a string / knit selection button 504, a drive control button 506, a cycle start button 508, a program setting 510, a value control button 512, a pusher on / off button 514, field / total bale count button 516, test button 518, and auxiliary output on / off button 520. In addition , there are a variety of buttons
    17/28 control including mesh 522, string 524, clutch 526, door 528, and pusher 540 and conveyor 542. A central display 540 is also provided that indicates the state of baler and conveyor for the operator during the various operating cycles of the baler and conveyor operating modes. In addition to the control console 500, a remote control (not shown) can also be used to manipulate some control functions that include the cycle start function described below.
    Controller 70 can be provided with a variety of operating modes: (1) neutral; (2) testing; (3) program; (4) activation; (5) semiauto; (6) manual, and (7) auto / continuous. The system starts in neutral mode. When the system starts up, certain checks are carried out by the system and the status of the baler and the conveyor is displayed to the operator. Starting from the neutral mode, the operator can press the test, adjustment, activation, or any of the mode keys.
    The test mode is entered when the operator presses the test button 518. The test mode is used to check the condition of the baler's electrical system components. This status will be displayed on the 540 console screen.
    The program mode is entered by pressing the 510 adjustment key. The operator uses the program mode to adjust the various settings to control the baler and conveyor functions. The program mode symbol will be illuminated. The configuration name and value will appear on the display screen. To change a configuration value or option, the operator can press the appropriate side of the 512 value key. The adjustment button can be pressed again to advance to the next configuration name. Among other values and configurations, the baler can be adjusted in automatic mode, also referred to as continuous mode, during program mode and a selected bale dimension conveyor scheme.
    18/28
    There are two semi-automatic modes: auto push and auto roll. In the self-pushing mode, the baler 12 will form a bale and wait for a signal before rolling the bale. Once the winding has been marked, the bale is rolled up and immediately ejected without operator intervention. In self-rolled mode the bale is automatically rolled after the predetermined bale size is reached and the baler waits for a signal from the operator before ejecting the rolled bale. In automatic or continuous mode, the formation of the bale, the self-pushing and self-rolling modes, as well as the movement of the conveyor, can be carried out without direct operator intervention. In continuous mode, the baler 12 can be towed across the field without stopping and the harvest material can be supplied continuously to the conveyor.
    The drive mode is entered by pressing the drive key 506. When the drive mode is entered the clutch is engaged and the forming belts 56 of the baler 12 begin to rotate and the conveyor motor 120 is driven and the conveyor belts 92 of the transporter 90 begin to turn. The operator can drive the harvester 22 or other forward vehicle by towing the baler 12 behind it and providing harvest material 16 for the conveyor belts 92. The operation of the various modalities of the baler 12 may be similar to that set out in U.S. Patent No. 6,675,561 entitled Semi Automatic Sequence Round Baler Baling Machine and Selectively Variable Point of Operator Intervention, which is incorporated by reference in this context, and includes the modalities of bale formation, bale wrapping, and bale ejection that they can be operated semi-automatically with some operator intervention or fully automatic without operator intervention. In any case, the operation of the conveyor 90 can be carried out automatically in response to the various modalities of the baler 12. For example, the conveyor can be programmed to move in response to different operating modes of the baler 12, be it the modalities
    19/28 of baler 12 carried out automatically, semi-automatically, or manually. The activation mode key 506 can be pressed either in manual mode, semi-automatic mode, or automatic (continuous) mode will be used to control the operating cycles of the baler. In semi-automatic mode, when the baler 12 completes all cycles to create and eject a bale 20 it will automatically return to the drive mode for subsequent cycles as described below. In automatic (continuous) mode the baler 12 and the conveyor 90 can switch continuously between the various modes until otherwise instructed and in this way the baler 12 can be towed continuously across the field and fed continuously with harvest material.
    The semi-automatic baler mode can be entered by first selecting one of the two modes, auto push or auto winding, during the program mode and then pressing the key 506 as described previously. The automatic or continuous mode can be entered by selecting the continuous mode during the program mode and then pressing the activation key 506 as previously described. Manual mode can be entered at any time by pressing one of the manual keys. Once in manual mode, the operator controls the forming cycle by controlling the clutch with the clutch button 526, the winding cycle by pressing either the mesh button 522 or the string button 524, the ejection cycle by controlling the rear hatch with the door button 528 and the pusher with the pusher button 530, and the conveyor by pressing the conveyor button 532. In addition to the conveyor on / off button, a speed button may be provided conveyor 550 and conveyor direction button 552 to manually control the speed and direction of the conveyor 90 when the system is operating in manual and / or semi-automatic modes. These 550, 552 buttons will send signals to controller 70 to manipulate the flow control valve
    20/28
    154 and the drive roller 94.
    The baler 12 and the conveyor 90 can operate as shown below. The variable displacement pump 88 inside the baler receives power from the vehicle's PTO 22 and pressurizes the system. When the operator signals the start of the bale-forming cycle by pressing the actuation button 506, the electronic controller 70 sends a signal to the clutch solenoid 472 which engages the clutch causing the starter roller 26 to start to rotate, and the upper and lower drive rollers 24, 28 rotate the forming belts 56, and the feeder 196, and sends a signal to the conveyor on solenoid 150 and the flow control valve 154 to excite the conveyor motor 120 in order to drive the conveyor drive roller 94 and move the conveyor belts 92 at a desired speed. The feeder 196 may comprise one or more augers provided with one or more flights which revolve around a common axis geometric axis and laterally internal forks of the augers extending radially from the axis. Alternatively, stump and fork augers can be provided on separate rotary axes. Feeder 196 may be driven from a starting roller drive as is known in the art, so that feeder 196 rotates when the baler belts 56 are in motion. The augers assist in the movement of the harvest material laterally inwards, towards the 198 of the baler
    12. For example, the conveyor 90 may have a width greater than the baler inlet 198 so that augers decrease the width of the mat of harvest material 16 provided by means of the conveyor 90 to a suitable width for receiving inside the inlet 198. The rotating forks can assist in feeding the harvest material 16 into the bale forming chamber 110 of the baler 12.
    The operator can move the baler 12 across the field by towing the baler 12 behind a harvester 22 that supplies harvest material 16 to the conveyor belts 92. For example, the harvester 22 can be configured to eject harvest material 16 from
    21/28 an outlet on the upper surface 98 of the conveyor belts 92. The conveyor belts 92 move the received harvest material to an inlet 198 of the baler 12. The harvest material 16 is then fed to the bottom of the bale chamber narrow open 198 by means of a auger 196. Once in the bale chamber 198, the harvest material contacts the rough top surface of the forming belts 56 which are in an upward motion. The forming belts carry the harvest material 16 to the top of the starting chamber which is formed by the front and rear bale density rolls 50, 52. The movement of the forming belts turns the harvest material down against the start 26. The core starts and starts to curl up. Hydraulic cylinders lower the bale density arm 48 and the belt tension arms 30. The bale density rollers 50, 52 are held down to reduce the size of the bale chamber to a starting dimension. The belt tension rollers 32, 34 are held down to supply tension to the forming belts. As the bale increases in size, the bale density rollers 50, 52 and the belt tension rollers 32, 34 are forced upwards. Bale density rolls 50, 52 apply an increasing amount of downward force against the bale. This force maintains tension in the bale and compresses the harvest material that is entering the bale chamber. The belt tension rollers move upwards to provide more forming belt for the increased dimension of the bale within the chamber.
    As the bale size increases and the bale density arm 48 is moved upward, the bale size sensor 68 continuously sends signals to the controller 70 indicating the bale size. Controller 70 will detect when the bale has reached or exceeded a desired bale dimension, which may have been originally programmed during the program mode by the operator. The bale size can also be displayed on the 540 console screen. If the baler 12 is operating in continuous mode, then when the bale size has reached or exceeds the pre-finished bale size 22/28, the baler 12 inserts the winding and the conveyor speed changes in response to the new baler mode. For example, conveyor 90 may be slowed or stopped during the winding cycle when baler 12 continues through the field and harvest material continues to be supplied to conveyor 90 via harvester 22 so that harvest material 16 accumulates on conveyor 90.
    In the winding cycle, controller 70 can activate either the 478 mesh feed solenoid or the string feed solenoid 450 to wind the bale, depending on the winding method selected during the program mode. The string winding mechanism or the mesh winding mechanism performs its function as will be easily understood by anyone skilled in the art. Once the winding cycle is completed, clutch solenoid 472 is deactivated via controller 70 to disengage the clutch and stop the movement of forming belts 56. The controller proceeds to the eject cycle. The conveyor 90 can remain in the slow or stopped drive condition, continuing to accumulate harvest material 16 as the baler 12 continues to move through the field during the ejection cycle.
    In the ejection cycle, controller 70 causes the rear hatch 58 to be lifted by activating the rear hatch raise solenoid 460. Once the rear hatch raise switch 484 is closed, signaling the position of the rear hatch to the controller 70, controller 70 drives pusher solenoid 470 causing the pusher to push the bale out of the baler. The pusher proceeds outward to its fully extended position or stops, closing pusher exit switch 488. The controller then activates the rear hatch lowering solenoid 464 causing the rear hatch 58 to move to the lowered position and closing the rear hatch lowering key 486 which in turn indicates the lowered position for controller 70. Controller 70 then causes the push solenoid 23/28 dor 470 to be deactivated. The rear hatch lock switches 434, 444 are closed, causing the clutch solenoid 472 to be excited and the forming belts 56 to rotate. Deactivating pusher solenoid 470 causes the pusher to return to the home position, closing the pusher home position switch 490. Then, baler 12 immediately begins a new forming cycle as discussed earlier and controller 70 restarts the conveyor 90 so that the harvest material accumulated on the conveyor 90 is supplied to the baler 12.
    If the operator selects the semi-automatic self-winding mode, the baler will form the bale as described above and, after a short delay, proceed directly to the winding cycle to roll the bale without operator intervention. The baler will then wait for operator intervention understood by pressing the cycle start button 508 or the remote cycle start key before starting the eject cycle. After receiving the operator input, the baler 12 will raise the rear hatch 58, unload the bale from the chamber, send the pusher out, lower the rear hatch, and send the pusher to the original position, as described earlier. When the rear hatch locks 434, 444 are closed, the forward drive arrow will be illuminated on the display 540. The conveyor 90 can automatically adapt its speed in response to the different baler modes 12. In a similar way, in a fully automatic (continuous), the baler 12 can move through the various cycles of bale formation, winding and ejection without operator intervention and the movement of the conveyor automatically changed according to the different operational cycles of the baler 12. If the operation is in a non-continuous mode, such as manual or semi-automatic mode, then the operator can control the movement of the conveyor 90 of the adjustable conveyor 14 by using the conveyor on / off button 532, the conveyor speed button 550, and the 552 directional button on the
    24/28 control console 500.
    Figure 6 shows an exemplary flowchart of a continuous baling operation in which the baler 12 can be moved continuously across the field through the various baling operation cycles without stopping and which allows continuous collection of harvest material 16 through the various cycles operation of the baler. In block 602, harvesting material 16 can be received continuously on the conveyor 90. For example, the harvesting material can be received on the conveyor through the various operating cycles of the baler 12 and as the baler 12 is towed across the field. In block 604 a baler operating cycle 12 is determined. For example, controller 70 can receive input from various sensors and switches to determine a desired cycle in which to operate baler 12 depending on a variety of factors, such as , as an example and not a limitation, the size of the current burden. In the block the conveyor 90 is adjusted in response to an operating cycle determined in block 604. For example, the conveyor can be stopped, accelerated, delayed, inverted and similar, according to the particular operating cycle of the baler.
    12.
    It should be noted that, although three particular operating cycles, bale formation, bale winding, and bale ejection were discussed, the term cycle should be understood as incorporating other existing or future operations that may be performed using a baler and you are not limited to the three cycles mentioned earlier. In this way, many other cycles can be performed by means of the baler 12, and the conveyor 90 adjusted in response to the various cycles. In addition, for convenience, the term modality was used to describe the movement and operation of the conveyor 90. It should be noted that the conveyor can be manipulated during the various modalities to change the speed or direction and modality and that although in some exemplary embodiments the conveyor mode corresponds to the operating cycles of the baler, other modes of operation
    25/28 may be used independently of the baler cycles and that the various modes of the conveyor may remain for longer or shorter periods than the operational modes of the baler.
    Figure 7 shows a flowchart of an exemplary embodiment of a method for continuous baling. Once the process is started in block 700, a determination is made in block 702 as to whether the system is operating in continuous mode. If the system is not operating in continuous mode, then the system operates in a manual mode or any other mode that has been selected. For example, an operator may have selected a manual or semi-automatic mode during program setup.
    If the baler is in continuous mode, then in block 706 the baler operates in an initial cycle. For example, the initial cycle may be the burden-forming cycle. The conveyor is then operated in an initial mode on block 708. The initial mode of conveyor 90 may be a desirable mode for use with an initial baler cycle 12. For example, the operating cycle of baler 12 is the formation cycle of the baler. bale, then the initial operating mode of the conveyor 90 may be movement at a first speed to provide harvest material for the baler 12.
    In block 710, a determination is made as to the possibility of changing baler cycles 12. For example, a determination can be made as to whether the baler is ready for a winding cycle by receiving information that the size of the bale that is being formed in the baler is larger than a predetermined dimension. If there is no time to change the baler cycle, then the baler can continue in its present cycle in block 712 and continue until it is considered appropriate to change the cycle. If this change is appropriate, then at block 714 the baler changes its operating cycle.
    In block 716, a determination is made as to the possibility of changing the mode of the conveyor. For example, under a scheme that can be employed, the conveyor can be programmed to change the modalities in changing a change in a baler operating cycle 12. If it is determined that the conveyor mode should not be changed, then in block 718 the carrier continues to operate in its present form. If it is considered that the carrier must change its mode, then in block 720 the carrier mode is changed. For example, the conveyor can be stopped, restarted, delayed, accelerated, inverted, and so on.
    In block 722, a determination is made as to whether the system is still in continuous mode. If not, then in block 704, the conveyor can be switched to manual mode or some other mode. If in block 722 it is determined that the system remains in continuous mode, then a new determination is made in block 710 as to the possibility of changing the balers' operating cycles. This process can continue to be repeated to allow a baler 12 to change between several operating cycles and the conveyor 90 to switch between various modes while the baler moves continuously across the field and harvesting material is supplied continuously to the conveyor 90.
    Figure 8 shows an exemplary method of operating an adjustable conveyor with a continuous baler in which the conveyor is operated in various modes that correspond to the particular operating cycles of the baler 12. In block 802, a determination is made as to whether the baler is in continuous mode. If the baler is not in continuous mode, then in block 804 the conveyor 90 is operated in manual mode (or any other mode that is selected by the operator) until the continuous mode is selected. In block 806, a determination is made as to whether the baler is operating in the bale formation cycle. If so, then in block 808 the conveyor 806 is operated in a corresponding bale-forming mode, that is, a mode
    27/28 which is desirable when the baler is in the bale formation cycle. For example, conveyor 90 can be driven forward at a particular speed in the bale-forming mode. If the baler is not in the bale-forming cycle in block 806 (or once the conveyor has switched to bale-forming mode in block 808), then in block 810 a determination is made as to whether the baler will find in the bale winding mode.
    If the baler is in bale winding mode in block 810 instead of in block 812 the conveyor is operated under a speed of bale winding mode. As previously discussed, the speed of the conveyor during the winding cycle can be zero, or in other words, the conveyor can be stopped. If the baler is not in bale winding mode in block 810 (or once the conveyor has been switched to bale winding mode in block 812), then a determination is made in block 814 as to whether the baler be in the ejection mode. If the baler is in the eject cycle, then in block 814 the conveyor is set to an ejection mode in block 816. As discussed earlier, the conveyor can remain stationary in ejection mode. The process then continues back to block 802.
    In the exemplary flowchart illustrated in figure 8, the conveyor has been established for different modalities that correspond to the different operating cycles of the baler 12. Figure 9 shows an exemplary embodiment of a flowchart in which the scheme employed to control the conveyor 90 includes additional factors. In block 900 the baler is started and in block 902 the baler 12 enters the bale formation cycle. In block 904, a determination is made as to whether the bale 20 is larger than a minimum dimension. For example, the bale size sensor 68 can be used to determine the size of the bale and transmit it to the controller 28/28 70. If the bale is not of sufficient size, then on block 906 the conveyor 90 is driven under a first speed, such as a low speed. This will allow more harvest material 16 to accumulate and limit the amount of harvest material 16 entering the bale chamber. The conveyor 90 will remain operating at low speed until it is determined that the bale is of sufficient size in block 904.
    If in block 904 the bale 20 is of sufficient size, then in block 908 the conveyor 90 is driven under a second speed, such as a high speed. In block 910, a determination is made as to whether bale 20 is of full bale dimension. If not, then conveyor 90 remains operating at second speed. If the bale is of sufficient size in block 910, then the conveyor is configured for a third speed, as stopped, in block 912. In block 914 the winding and ejection cycles are performed and in block 916 a determination is made as to the possibility that the winding and ejection cycles are complete. If so, then the process is repeated on block 904 and the conveyor is driven under the first speed on block 906.
