    A rectangular baler with ejector system
    The present invention relates to a rectangular baler with ejector system.
    WO96 / 29195, believed to be the closest prior art to the present invention, discloses a rectangular baler that, instead of using the press plunger to load the bound bales from the bale chamber, an additional ejection system to allow the operator to unload the finished bales. The ejector system contains a shuttle unit which is located in the hollow rails of the bale chamber. The shuttle unit consists of a frame that is moved back and forth in the direction of movement of the press plunger and has upwardly directed pins to engage in the bottom of the bales. The pins only grasp the bale during the forward stroke of the shuttle unit, that is, when it moves toward the eject opening of the bale chamber and drags relative to the bottom of the bale during the return stroke. In this way, the shuttle unit moving back and forth moves the bales incrementally to the discharge opening.
    The ejector mechanism of WO96 / 29195 is steerable to allow the operator to eject only the last bale in the bale chamber (the bale closest to the ejection opening) or both the last bale and the bale before it. To achieve this, the pins are placed on the shuttle in a lengthwise series and at least some of the pins are controllable by the operator using a selection unit so that the controllable pins can be positioned to extend into the to reach the bale chamber or to be withdrawn.
    Apart from the complexity resulting from the need to control individual pins, the ejector system of WO96 / 29195 suffers from the disadvantage that the operator must first examine the position of the bales in the bale chamber to be able to decide which pins to activate.
    The present invention has for its object to provide an ejection system for a rectangular baler that offers an answer to the foregoing disadvantages of the prior art.
    According to the present invention, there is provided a rectangular baler comprising a bale chamber in which crop is compressed by means of a plunger, which has an ejection opening at one end of the bale chamber and which has an ejection system for moving bales to the ejection opening independent of the movement. of the press plunger, the ejector system includes a shuttle unit mounted in a wall of the bale chamber to move back and forth in parallel to the direction of movement of the bales in the bale chamber, and at least one pin mounted on the shuttle unit to engage the last bale in the bale chamber positioned closest to the ejection opening and to move the bale incrementally out of the ejection opening as a result of the shuttle unit moving back and forth, characterized in that a second shuttle unit is arranged in a wall of the bale chamber to move back and forth independently of the first shuttle unit, the second shuttle unit comprises at least one pin arranged thereon for engaging the penultimate bale in the bale chamber.
    The second shuttle unit may suitably contain a series of pins distributed over its entire length and may be able to advance the bales up to the ejection opening of the bale chamber.
    In this case, moving the second shuttle unit back and forth will suffice to move both the last bale and the penultimate bale to the discharge opening.
    According to a variant, the second shuttle unit can be designed to only move the penultimate bale to a position where it will be taken by the first shuttle unit. In this case, both shuttles must be moved back and forth to eject the penultimate bale into the bale chamber.
    Thus, without taking into account the exact positions of the finished bales in the bale chamber, the operator can choose to only eject the last bale by operating the first of the shuttle units or to eject both the last and the penultimate bale. by reciprocating the second shuttle unit either on its own or in conjunction with the first shuttle unit.
    An important advantage of the present invention is that the pins do not have to be controlled, i.e. selectively switched on or off. According to a preferred embodiment of the invention, each pin is tiltably mounted on the shuttle unit and designed to act as a pawl in a pawl and ratchet mechanism. Thus, each pin will tilt into an excellent gripping position during the forward movements of the shuttle to advance the bale to the ejection opening and will retract during recurring movements of the shuttle unit to slip relative to the bale.
    If tilting pins are used, they can be pre-set in their protruding position by means of gravity or by means of a spring. According to a variant, the pins can be designed to slightly penetrate into the bale chamber when they are withdrawn, so that they will automatically be lifted to their projecting position as they engage in the bale.
    The invention will now be further described, by way of example, with reference to the accompanying drawing, Figure 1, which is a schematic perspective view of the ejection system using two shuttle units.
    The integration of an ejector system in a rectangular baler is well illustrated in the prior art. WO96 / 29195 has various drawings which show how the ejector system is mounted in the baler.
    In the interest of simplicity, the following description will focus on the construction of the ejector system and will only describe the bale chamber as necessary for understanding the invention.
    To ensure that it contains sufficient rigidity, the bale chamber floor is not formed as a continuous flat surface. The floor can be formed from a metal plate bent to provide longitudinally extending channels or it can be formed from individual tubes with rectangular section that are welded to cross beams that leave grooves open at their ends between the individual tubes. The shuttle units of ejector systems are designed to sit between such longitudinal grooves, channels or open rails with only their pins that are capable of extending upwardly above the floor surface on which the bales are supported.
    The ejector system according to the accompanying drawing comprises two shuttle units 10, 12, one arranged inside the other and designed to share the same longitudinal grooves or rails in the floor of the bale chamber.
    The first and inner of the two shuttle units comprises two longitudinally extending vertical slats 101, each slat of which carries two tilting pins 102 on the inside of its front end closest to the discharge opening of the baler. The number of pins arranged on the front end of the inner shuttle unit is not critical, provided that a single pin is sufficient or more than two pins could be used, provided that they can only grasp the last of the bales in the bale chamber.
    The two slats 101 are connected to each other by means of a crossbar 103 which lies under the floor of the bale chamber. A bracket 104 connects the crossbar 103 to a hydraulic cylinder 105 which lies in a channel of the floor and is fixed by means of brackets 106 at its other end to the sides of that channel.
    The outermost of the two shuttle units 12 comprises two longitudinally extending slats 121 immediately adjacent to and back to back with the slats 101 of the first shuttle unit. Each of these slats 121 carries a series of pins 122 on its outside. The two slats 121 are connected to each other by means of a crossbar 123 that is further below the floor of the bale chamber than the crossbar 103 of the first shuttle unit. A bracket 124 connects the crossbar 123 with a hydraulic cylinder 125, which in this case lies completely under the floor of the bale chamber. The other end of the hydraulic cylinder 125 is connected to a bracket (not shown) that is directed downwards from the bottom of the bale chamber floor.
    The main purpose of the described design of the two shuttle units is to allow each of the two units to be moved back and forth without interfering with each other. The design also aims to reduce the amount over which the hydraulic cylinders 105, 125 protrude from the underside of the floor of the bale chamber, this is accomplished by accommodating one of the cylinders 105 within the depth of the floor itself.
    Each pin 102, 122 is designed to act as a toothed pawl. As shown in the figure, each pin 102, 122 is triangular in shape and pivotally mounted on its associated slat at a point offset from its center of gravity so that each pin tends to tilt naturally toward the retracted position (as shown) . Small stops 107, 127 in the vicinity of each tip point for a pin act as stops to limit in both directions the arc over which the associated pin can tilt. In the clockwise direction, the pins are stopped in a position in which they protrude a little above the floor of the bale chamber in the volume covered by the bales. Counter-clockwise the pins are stopped near a vertical position to maximize their reach and grip on the bales.
    The positioning of the discharge system is such that the pins 102 of the first shuttle unit 10 can only engage the last bale in the bale chamber. When the cylinder 105 is fully retracted, the pins 102 engage furthest from the discharge opening near the front end (the end closest to the discharge opening) of the last bale. When the cylinder 105 has fully extended, the pins 102 engage closest to the discharge opening near the rear end of the last bale. The front end of the bale will then be advanced on the discharge line of the baler.
    Thus, by moving the inner shuttle unit 10 back and forth on its own, only the last bale will be ejected into the bale chamber, provided that its front side has reached the position in which it can be gripped by one of the pins 102 of the first shuttle unit.
    The second shuttle unit 12 has pins 122 which can also advance the last bale to the discharge opening. However, in contrast to the first shuttle unit 10, the second shuttle 12 has pins that extend as far back as the penultimate bale in the bale chamber. Consequently, the reciprocating movement of the second shuttle unit through the cylinder 125 will eject the last and the last but one bales.
    It is not essential that the second shuttle unit be able to move the penultimate bale up to the discharge opening. Instead, it would suffice for the second shuttle to move the penultimate bale to a position from which it can be picked up by the first shuttle unit. For this it is possible to place the second shuttle unit completely behind the first, instead of arranging them both next to each other as shown. According to such an embodiment, the second shuttle unit can simply be a duplicate of the first, which makes it possible to manufacture the two units from similar or identical components. Such an embodiment can reduce the extent to which the ejector system protrudes below the floor of the bale chamber since the two cross members 103 and 123 can now both be arranged at the same horizontal level and both cylinders 105 and 125 can be housed within the depth of the floor. A further advantage of such an embodiment is that it would not be required for the cylinder 125 to have sufficient force to move two bales at the same time.
