    Rectangular baler with a wall positioning system and a wall positioning method
    Field of application of the invention
    The field of application of the invention relates to a rectangular baler with a wall positioning system and a wall positioning method for a rectangular baler comprising a bale chamber with several walls, including a movable wall section.
    Background
    According to the state of the art, rectangular balers include positioning means configured to pivotally move a movable wall section of a bale chamber. When a large pressure is exerted on the movable wall section, this typically leads to a difficult to control change in the angle of inclination of the movable wall section. Consequently, the cross-section of the bale chamber towards the end may become narrower or wider. If the cross section becomes too narrow, this could lead to deformed bales and if the cross section becomes wider, the bales may inadvertently expand.
    Summary
    The object of the embodiments of the invention is to provide a rectangular baler with an improved wall positioning system and an improved wall positioning method for a rectangular baler.
    According to a first aspect of the invention, a rectangular baling press is provided with a wall positioning system, wherein the baling press comprises a baling chamber containing several walls; including a movable wall section. The wall positioning system comprises positioning means for moving the movable wall section from a first position to a second position. The positioning means are configured to exert pressure on a first pressure point and on a second pressure point of the movable wall section so that the second position of the movable wall section is substantially parallel to the first position of the movable wall section. The first pressure point and the second pressure point are located at a certain distance from each other in a longitudinal direction of the bale chamber.
    Embodiments are based, inter alia, on the insight of the invention that by exerting pressure at two pressure points which are a certain distance apart in a longitudinal direction of the bale chamber, a more accurate positioning of the movable wall section can be obtained than as the pressure is only exercised at one pressure point. This approach to moving the movable wall section from a first position to a second position leads to a more accurate positioning of the movable wall section. By moving the movable wall section from a first position to a second position so that the second position of the movable wall section is essentially parallel to the first position of the movable wall section, it is possible to keep an angle of the movable wall section constant while the pressure inside the bale chamber increases.
    In exemplary embodiments of the invention, the movable wall section can be a movable top door, a movable side door, or a movable bottom door.
    The wall positioning can be carried out for all movable doors or for a number of movable doors.
    In certain embodiments, the movement of, for example, two side doors can be mechanically or hydraulically coupled, in which case the wall positioning can take place on only one side door, the other side door automatically following the first side door.
    In a preferred embodiment, the positioning means comprise actuator means for applying pressure to the first pressure point, and coupling means for providing a coupling between the first pressure point and the second pressure point. The coupling means are configured to transfer pressure applied to the first pressure point to the second pressure point. This approach permits accurate movement of the upper wall section by only actively applying pressure via the actuator means at one pressure point of the movable wall section. The coupling means are configured to transfer the actively applied pressure to the second pressure point in such a way that an equal pressure is applied to both the first pressure point (active by the actuator means) and to the second pressure point (passively by the coupling means), which leads to a translational movement of the movable wall section, wherein a start position and end position of the movable wall section are essentially parallel.
    In a possible embodiment the coupling means can provide a mechanical coupling or a hydraulic coupling between the first and the second pressure point.
    In a preferred embodiment the coupling means comprise a rod which is arranged substantially parallel to the movable wall section. The rod is pivotally connected at a first end to a frame of the baler and to a point on the movable wall section close to the first pressure point. At a second end the rod is hingedly connected to the frame of the baler and to the second pressure point. This approach allows a simple mechanical coupling between the first pressure point and the second pressure point and an accurate positioning of the movable wall section.
    In an alternative embodiment, the coupling means comprise an actuator.
    In an exemplary embodiment the actuator means comprise a hydraulic cylinder which is attached to the frame of the baler and which is arranged substantially perpendicularly to the movable wall section. The hydraulic cylinder is configured to apply pressure to the first pressure point.
    In one embodiment, the wall positioning system comprises a control unit that is configured to control the actuator means to move the movable wall section to the second position.
    In a preferred embodiment the positioning means comprise first actuator means for exerting pressure on the first pressure point and second actuator means for exerting pressure on the second pressure point. In this way the pressure is actively applied to both pressure points.
    In an exemplary embodiment, the wall positioning system further comprises a control unit that is configured to control the first actuator means and the second actuator means to move the movable wall section to the second position. This approach makes it possible to control separately the magnitude of the pressure applied to the first pressure point and to the second pressure point.
    In a preferred embodiment, the first actuator means are controlled to apply a certain pressure and the second actuator is configured to follow the first actuator by means of a hydraulic clutch.
    In a preferred embodiment the first actuator means comprise a first hydraulic cylinder, which is attached to the frame of the baler and is arranged substantially perpendicularly to the movable wall section. The first hydraulic cylinder is configured to apply pressure to the first pressure point. The second actuator means comprise a second hydraulic cylinder which is attached to the frame of the baler and is arranged substantially perpendicularly to the movable wall section. The second hydraulic cylinder is configured to apply pressure to the second pressure point.
    In a preferred embodiment, the first position of the movable wall section is substantially parallel to a wall section disposed opposite the movable wall section.
    According to another aspect of the embodiment, a rectangular baler is provided which includes a wall positioning system according to any of the preceding embodiments.
    In a preferred embodiment, the rectangular baler comprises a bale chamber which comprises a bottom wall and a top wall. The top wall contains a movable top wall section and a hinged top wall section. Viewed in a longitudinal direction of the baling press, a first end of the hinged top wall section is hingedly connected to a frame of the baling press at a plunger end of the baling chamber. A second end of the hinged top wall section is hingedly connected to the movable top wall section, so that the top wall can have a kink at the location where the hinged top wall section is connected to the movable top wall section. The movable top wall section and the hinged top wall section which are arranged so that they form a so-called variable buckle. The positioning means are configured to exert pressure on a first pressure point and on a second pressure point of the movable top wall section such that the second position of the movable top wall section is substantially parallel to the first position of the movable top wall section. The first pressure point and the second pressure point are spaced apart at a predetermined minimum distance in a longitudinal direction of the bale chamber.
    In a further embodiment, the rectangular baler comprises a bale chamber which contains a first side wall and a second side wall. The first side wall includes a movable side wall section and a hinged side wall section. Viewed in a longitudinal direction of the baling press, a first end of this hinged side wall section is hingedly connected to a frame of the baling press at a plunger end of the baling chamber. A second end of the hinged side wall section is hingedly connected to the movable side wall section, so that the first side wall can have a kink at the location where the hinged side wall section is connected to the movable side wall section. The movable side wall section and the hinged side wall section thus arranged form a so-called variable buckle. The positioning means are configured to exert pressure on a first pressure point and on a second pressure point of the movable side wall section such that the second position of the movable side wall section is substantially parallel to the first position of the movable side wall section. The first pressure point and the second pressure point are at a certain distance along a longitudinal direction of the bale chamber.
    Those skilled in the art will recognize that the technical considerations and advantages described above for embodiments of the system also apply mutatis mutandis to the embodiments of the method described below.
    According to yet another aspect of the invention, a method for positioning a wall is provided for a rectangular baler comprising a bale chamber with a plurality of walls, including a movable wall section. The method for positioning a wall consists in moving the movable wall section from a first position to a second position by applying pressure to a first pressure point and to a second pressure point of the movable wall section so that the second position of the movable wall section is essentially parallel to the first position of the movable wall section. The first pressure point and the second pressure point are at a certain distance along a longitudinal direction of the bale chamber.
    In an exemplary embodiment, moving the movable wall section from the first position to the second position consists in directly applying pressure to the first pressure point and providing a coupling means between the first pressure point and the second pressure point. The embodiment further consists in transferring pressure exerted at the first pressure point to the second pressure point via the coupling means.
    In a preferred embodiment the coupling means comprise a rod which is arranged substantially parallel to the movable wall section. The rod is pivotally connected at a first end to a frame of the baler and to a point on the movable wall section close to the first pressure point. At a second end the rod is hingedly connected to the frame of the baler and to the second pressure point.
    In an exemplary embodiment, moving the movable wall section from the first position to the second position consists in directly applying pressure to the first pressure point and directly applying pressure to the second pressure point.
    According to a preferred embodiment, the first position of the movable wall section is substantially parallel to a wall section arranged opposite the movable wall section.
    According to a further aspect of the invention, there is provided a computer program which includes computer-executable instructions to perform the method when the program runs on a computer according to any step of any of the embodiments disclosed above.
    According to yet a further aspect of the embodiment, a computer device or other device is provided that is programmed to perform one or more steps of any embodiment of the method disclosed above.

    Description of embodiments
    Figure 1 illustrates an exemplary embodiment of a rectangular baler wall positioning system including a bale chamber 100 containing a series of walls 110, 120, including a movable wall section 101 (see Fig. 3B), 111. The wall positioning system includes positioning means 130 to move the movable wall section between a first position (p1) wherein the movable wall sections are moved outward to create the largest cross-section available in the bale chamber 100, and a second position (p2), where the movable wall sections move toward be moved inside to create the smallest possible cross section available in the bale chamber. The actual position of the movable wall sections depends on the magnitude of the pressure P to be applied to harvesting material in the bale chamber 100 in order to achieve a specific density of the bales. The positioning means 130 are configured to exert pressure P on a first pressure point 112 and on a second pressure point 113 of the movable wall section 111 so that the movable wall section 111 remains essentially parallel when it is moved between the first position (p1) and the second position (p2). In Figure 1, the first pressure point 112 and the second pressure point 113 are spaced apart (d) along a longitudinal direction of the bale chamber. Preferably, there is a distance of approximately 2 m between the first pressure point 112 and the second pressure point 113. However, the preferred distance may vary depending on the dimensions of the baler and the bale chamber 100.
    For the sake of completeness, it is stated that the left-hand side of the drawings shows an entry section of the bale chamber 100. Harvesting material is thus introduced into the bale chamber 100 on the left-hand side by a plunger 180 (shown only in Figures 6A, 6B and 6C). When harvest material is pushed through the bale chamber 100 and the positioning means 130 exerts a force on the movable wall section 111, the movable wall section 111 is moved to the second position (p2) where it is pressed against the harvest material and the bales formed in the bale chamber 100 .
    Although the movable wall section 111 is shown in the Figures as a movable top wall section or upper door in the Figures, it should be clear to a person skilled in the art that the movable wall section is a movable top door 111, a movable side door 101 or a movable bottom door 121 and that the principles of the invention are certainly applicable in any case. A combination of any movable door is also possible: the wall positioning can be performed for all movable doors or for a number of movable doors. In certain embodiments, the movement of, for example, two side doors can be mechanically or hydraulically coupled, in which case the wall positioning would only be carried out on one side door, the other side door automatically following the first side door.
    Figure 2 illustrates an embodiment of a wall positioning system, wherein the positioning means 130 comprise actuator means 131 for applying pressure to the first pressure point 112 and coupling means 132 for providing a coupling between the first pressure point 112 and the second pressure point 113. The coupling means are configured to transfer pressure applied to the first pressure point 112 to the second pressure point 113.
    The wall positioning system may further include a control unit 160 that is configured to control the actuator means 131 to move the movable wall section 111 to the second position.
    Figures 3A and 3B illustrate an embodiment of the wall positioning system and a rectangular baler with a wall positioning system, respectively, wherein the coupling means 132 comprise at least one rod 332 which is arranged substantially parallel to the movable wall section 111. The at least one rod 332 is at a first end 141 is pivotally connected to a frame 150 of the baler and to a point of the movable wall section close to the first pressure point 112, and is pivotally connected at a second end 142 to the frame 150 of the baler and to the second pressure point 113. At the first end 141, the at least one rod must be connected by a hinge with a point that is in the vicinity of the first pressure point 112, so that when the actuator means 131, 331 press on the first pressure point 112 of the movable wall section 111, the movement of the wall section has the hinge connection at the first end 141 of the at least one bar 332 will open. When the hinge connections open at the first end 141, they will at least cause one rod 332 to be pressed toward the second end 142 of the at least one rod 332. The movement of the at least one rod 332 will then cause the hinge connection at the second end 142 to open and therefore cause it to press on the second pressure point 113 of the movable wall section 111. Although it is preferable that the first end 141 of the at least one rod 332 is pivotally connected to the frame 150 close to the first pressure point 112, this connection to the frame 150 may be located anywhere within a holding zone defined by section 11 lb. In this case, an additional structure may be required to connect the at least one rod 332 to the frame 150.
    According to a preferred embodiment, the actuator means 131 comprise a hydraulic cylinder 331 which is attached to the frame 150 of the baler and is arranged substantially perpendicular to the movable wall section 111. The hydraulic cylinder 331 is configured to apply pressure to the first pressure point 112.
    Figure 4 illustrates an exemplary embodiment of a wall positioning system, wherein the positioning means 130,430 first actuator means 431
    I for applying pressure to the first pressure point 112 and second actuator means 432 for applying pressure to the second pressure point 113.
    The wall positioning system may further include a control unit 460 configured to control the first actuator means 431 and the second actuator means 432 to move the movable wall section 111 between the first position (p1) and the second position (p2).
    Figure 5 illustrates a further embodiment of a wall positioning system in which hydraulic cylinders are used as actuator means to exert pressure on the movable wall section. The first actuator means 431 includes a first hydraulic cylinder 531 attached to the frame 150 of the baler and disposed substantially perpendicular to the movable wall section 111. The first hydraulic cylinder 531 is configured to exert pressure on the first pressure point 112. The second actuator means 432 comprises a second hydraulic cylinder 532 which is attached to the frame 150 of the baler and is arranged substantially perpendicular to the movable wall section 111. The second hydraulic cylinder 532 is configured to apply pressure to the second pressure point 113. In the embodiment illustrated in Figure 5, the position of the movable wall section 111 is essentially parallel to a wall section 121 disposed opposite the movable wall section 111.
    Figures 6A, 6B and 6C each illustrate a portion of a rectangular baler that includes a wall positioning system according to various exemplary embodiments. The baler contains a bale chamber 100 that includes a bottom wall 120 and a top wall 110. For the sake of completeness, a plunger 180 of the baler is illustrated to indicate the plunger side of the baler. The plunger 180 is used to compress harvest material into the bale chamber 100. The baler, part of which is illustrated in Figures 6A, 6B and 6C, has a so-called variable bend, the top wall 110 including a movable top wall section 11b and a hinged top wall section 11a. Viewed in a longitudinal direction of the baler, a first end of this hinged upper wall section is hingedly connected to a frame 150 of the baler at a plunger end of the bale chamber 100. A second end of this hinged upper wall section 11a is hingedly connected to the movable upper wall section. 111b, so that the top wall 110 can have a kink at the location where the hinged top wall section 11a is connected to the movable top wall section 111b.
    By having a top wall with variable bend 11a, 11b, the bale chamber can be divided into a compression zone defined by section 11a, and a holding zone defined by section 11b. If it is desired to have the section 111b parallel to the bottom wall 120, two points of the section 11 lb can be printed. Because there is an extra hinge between the compression zone and the holding zone, it is preferable to press at least two points. Although Figures 6A, 6B and 6C all illustrate embodiments in which the movable top wall section 111b is kept parallel to the bottom wall 120, it is also possible, in the case that the first position or starting position of the movable top wall section is at a certain angle with respect to the bottom wall to keep the movable top wall section 111b at that angle with respect to the bottom wall while the movable top wall section is moved, to a position parallel to the first position or starting position.
    Figure 6A illustrates an embodiment in which the positioning means 130 are configured to exert pressure on a first pressure point 112 and on a second pressure point 113 of the movable upper wall section 111b so that the second position of the movable upper wall section 11 lb is substantially parallel to the first position of the movable top wall section 11 lb. The first pressure point 112 and the second pressure point 113 are spaced apart along a longitudinal direction of the bale chamber. It is possible to place the movable top wall section 111b at a certain angle with respect to the bottom wall if different pressures are applied to the pressure points 112 and 113.
    In the embodiment of Figure 6C, two hydraulic cylinders 531, 532 are used as actuator means to exert pressure on the movable upper wall section 11 lb. The first actuator means comprises a first hydraulic cylinder 531 which is attached to the frame 150 of the baler and is arranged substantially perpendicularly to the movable upper wall section 11 lb. The first hydraulic cylinder 531 is configured to exert pressure on the first pressure point 112. The second actuator means comprises a second hydraulic cylinder 532 mounted on the frame 150 of the baler and arranged essentially perpendicularly to the movable wall section 11 lb. The second hydraulic cylinder 532 is configured to apply pressure to the second pressure point 113. Pressure of a specific size is applied to the first pressure point by the first hydraulic cylinder 531, while pressure of a specific size is applied to the second pressure point 113 by the second hydraulic cylinder 531, which leads to placing the movable top wall section 11b in a substantially parallel position with respect to the bottom wall 120. When the movable top wall section 111b is to be angled, the first hydraulic cylinder 531 will be less or have to apply more pressure to the first pressure point 112, and / or the second hydraulic cylinder 532 will have to apply less or less or more pressure to the second pressure point 113, compared to the pressure exerted in the parallel situation of the movable wall sections. Now, the end of the movable upper wall section 11b facing away from the plunger 180 will be pushed inside the bale chamber 100 toward the front of the movable upper wall section 111b.
    In the embodiment of Figure 6B the coupling means comprise a rod 332 which is arranged substantially parallel to the movable upper wall section 11 lb. The rod 332 is pivotally connected at a first end 141 to a frame 150 of the baler and to a point of the movable upper wall section 111b close to the first pressure point 112. At a second end 142, the rod is pivotally connected to the frame 150 of the baler and with the second pressure point 113. The actuator means in Figure 6B comprises a hydraulic cylinder 331 which is attached to the frame 150 of the baler and is arranged substantially perpendicularly to the movable upper wall section 11 lb. The hydraulic cylinder 331 is configured to apply pressure to the first pressure point 112. In this embodiment, the movable top wall section 11 lb always remains parallel to the bottom wall.
    When the rod 332 is replaced by an actuator such as a hydraulic cylinder (not shown), it is also possible to arrange the movable upper wall section 111b at an angle. When the pressure is exerted via the hydraulic cylinder 331 at the first pressure point 112, the actuator 332 can be extended such that the end of the upper wall section 111b will be pressed inward, whereby the formed bale will clamp better in the bale chamber compared to its bale chamber. parallel situation. If the actuator 332 is retracted, the end of the upper wall section 111b will be pushed out more and thus clamp the formed bale less than in the parallel situation and the formed bale will be pushed out of the bale chamber more easily.
    Other possibilities that have the same effect are also possible, such as replacing the rods between the chassis 150, the upper wall section 111b and / or the first 141 and / or second 142 pivot points by actuators.
    In the embodiments and figures described above, for the sake of simplicity, the wall positioning system is illustrated in a linear configuration, wherein the two pressure points 112, 113 on the movable wall section 111, 111b can be connected by an imaginary line along a longitudinal direction of the baler or bale room. A person skilled in the art will recognize that according to the alternative embodiments of the invention, the wall positioning system can contain a series of such linear configurations, which are arranged essentially parallel to each other. In such embodiments, not only is printed at two points positioned on an imaginary line in the longitudinal direction of the bale chamber, but also placed at least two points on an imaginary line in a side direction of the bale chamber. In such an exemplary embodiment, the wall positioning system includes two density rings, so that two rings exert pressure on the sections around the holding zone of a bale chamber. In a preferred embodiment, the two rings can be coupled by providing coupling means that can include a plurality of rods 332 as mentioned in the embodiment of Figure 3. An exemplary embodiment of a wall positioning system that includes two parallel linear configurations is shown in the Figures 7A, 7B and 7C.
    Figure 7A illustrates an embodiment in which the hinged top wall section 11a and the movable top wall section 111b are aligned relative to each other. The side wall sections 111b are also shown aligned with respect to each other. In this position, compared to the position p1 of Figure 1, the bale chamber 100 assumes its widest position, and the crop material can expand within this volume of the bale chamber. The hydraulic cylinders 331 are then fully retracted so that the movable wall sections can be placed outwards. Although the harvest material presses against the wall sections in the bale chamber, it is nevertheless preferable that the hydraulic cylinders 331 pull out the doors. A combination of the hydraulic cylinders and a spring arrangement is thus possible, so that the hydraulic cylinders are assisted in pulling the doors out to the position as illustrated in Figure 7A.
    Depending on the stroke of the hydraulic cylinders 331, it is even possible to place the hinged wall section 11a and the movable wall section 111b more outwards, so that the hinged wall section 11a and the movable wall section 111b are no longer essentially aligned with each other, show a kink in the slope. In this way, the movable wall section (111b) is positioned more outward than the hinged wall section and the bend determines an angle that is opposite to the angle determined by the movable wall section and the hinged wall section when pressure is exerted on the movable wall section. Positioning the movable wall section 111b more outward will even lead to an even greater increase in the cross-section of the bale chamber.
    Anyway, if more pressure is to be exerted on the harvest material so that a higher density of the harvest material can be achieved, the movable upper wall section and / or side wall sections must be moved more towards the inside of the bale chamber 100, as shown in Figure 7B . The hydraulic cylinders 331 now exert a force F on the first pressure point 112, and press the movable upper wall section 11 lb more towards the inside of the bale chamber 100. The movement of the upper wall section 11 lb will cause the hinge connections on the first end 141 of the rod 332 open. When the hinge connections open at the first end 141, they will cause the rod 332 to be pushed toward the second end 142 of the rod 332. The movement of the rod 332 will then cause the hinge joints to open at the second end 142 and therefore cause them to press on the second pressure point 113 of the movable wall section 111. The position of the movable top wall section 11 lb is a direct result of the magnitude of the pressure exerted on the hydraulic cylinders 331. Accordingly, the position of the movable side walls is a direct result of the magnitude of the pressure exerted on the movable side walls through the hydraulic cylinders 331. The same applies to the construction of the movable side walls. Figure 7C shows the movable wall sections in their maximum inward position in the bale chamber 100. In this position, similar to position p2 of Figure 1, the hydraulic cylinders 331 are extended to their maximum stroke.
    The person skilled in the art understands that embodiments of the wall positioning system can contain more than two pressure points arranged on an imaginary line along a longitudinal direction in the bale chamber.
