Definitions
- Balers are machines used in agriculture for the purpose of creating bales of (typically) straw or other biomass such as hay or silage produced during a harvesting or mowing operation.
- baler Various designs of baler have been proposed in the prior art.
- a common characteristic of virtually all balers is that they are towed behind agricultural vehicles such as tractors.
- a baler includes an infeed via which biomass is ingested into the interior of the baler and compressed or otherwise treated to form bales.
- the completed bales are tied with twine to make them rigid and self-supporting and are ejected via a discharge chute typically at the rear of the baler machine so as to fall or be placed on the ground behind the tractor / baler combination as its moves forwardly along a harvested field.
- balers produce cuboidal bales that have a number of advantages over "round” bales.
- Rectangular bales can be produced with a high density. When used rectangular bales are also easily distributed as they are formed from a number of slices.
- baled straw is assessed on the basis of the weight of each bale produced by the operation of the baler. It can be very important to control the density of the baled biomass in order to assure that the bale weights are substantially constant during passage of a baler from part of a field to another. Variations however in the characteristics (especially the moisture) of the straw ingested from place to place into the baler may mean that there is a frequent or even constant need to adjust bale density during baling operations in order to meet the objective of consistent bale mass.
- the baler includes an substantially cuboidal bale-forming chamber. It is known in the art to construct the bale-forming chamber with one or more moveable side walls. The positions of the side walls can be adjusted so as to alter the volume of the bale-forming chamber and thereby squeeze the bale to a greater or lesser degree during its formation. If as is commonplace in a baler each charge of biomass ingested is substantially of constant volume, causing a reduction in the volume of bale-forming chamber in this fashion leads to the creation of higher density bales, and vice versa. This in turn provides an ability to control the densities of the formed bales.
- each charge introduced into the bale-forming chamber is, at the point of introduction, uncompressed or compressed to a relatively low level. It is moved along the bale-forming chamber by longitudinal strokes of a piston that reciprocates under the action of an attached arm that in turn is driven by a bell crank secured to a rotating member. Each stroke of the piston therefore compresses an amount of biomass against the biomass already available in the bale-forming chamber; and in consequence the density of the formed bale increases if the volume into which the biomass is swept is reduced as a result of adjustments of the positions of the sidewalls of the chamber at locations "downstream" of the furthest point reached by the piston during its motion.
- bales are fixed firstly because of the cross-sectional dimensions of the bale-forming chamber and secondly because the baler forms the biomass into identical bale lengths that are ejected via the discharge as substantially identical, individual bales.
- FIG. 1 An example of an adjustable bale-forming chamber sidewall is shown in US 4,037,528.
- This disclosure describes sidewalls that are moveable under the influence of cam-like arms that are caused to rotate by attached hydraulic rams.
- the arrangement defines a pair of four-bar linkages each including one of the sidewalls. Operation of the associated ram therefore causes the sidewall to move inwardly or outwardly, relative to the interior of the bale-forming chamber, in an even fashion causing uniform alteration of the chamber volume over a portion of its length.
- the ability to adjust the density of bales is likely to be of most use if the baler includes a feedback control loop for the purpose of assessing whether the actual bale density achieved matches a target density value.
- EP 1 935 232 It is known from EP 1 935 232 to provide a weighing device for the purpose of weighing discharged bales.
- the bale discharge chute includes a pivotable portion.
- the purpose of the pivotable portion is to alter the trajectory of a completed bale as it slides along the discharge chute. This in turn provides the advantage of controlling discharge of a completed bale in such a fashion that the bale suffers minimal damage on exit from the baler and lies in a predictable orientation in the field.
- the pivoting section of the discharge chute in the device of EP 1 935 232 incorporates one or more sensors for sensing the bale mass and generating a signal that is indicative thereof.
- EP 1 935 232 does not disclose use of a bale mass signal in conjunction with adjustable side walls of a bale-forming chamber.
- US 2,796,825 discloses a hydraulic control system for a rectangular baler.
- the output of a weighing platform in the discharge chute is generated as an hydraulic pulse.
- the pulse is used as an input command to a piston that adjusts the positions of sidewalls in a bale-forming chamber.
- bale mass measurements are used to adjust bale density.
- a tractor towing a baler across a harvested field however may attain a speed of perhaps 15 km / h when travelling over windrows. During the time required to form a single bale, therefore, the tractor / baler combination will travel at least 200 metres. The characteristics of eg.
- bale weight signals generated using the apparatus of US 2,796,825, being updated say once every 50 seconds, are relatively unlikely to be capable of taking account of such variations.
- the control system in US 2,796,825 is able to resolve the bale mass data only to an accuracy of 200 metres of baler travel, which is very unlikely to be sufficiently accurate as to provide acceptable control over bale density adjustments.
- a square baler comprising a biomass feed connected to a bale-forming chamber, a piston that is reciprocable in the bale-forming chamber in order to compress biomass fed into the bale-forming chamber via the biomass feed and form bales and a bale discharge, the dimensions of part of the interior of the bale-forming chamber being adjustable under the influence of at least one actuator the energization of which is controlable; the baler comprising:
- the first signal is fed back in a first control loop and compared with the target weight value in order to generate a target force value
- the second signal is fed back in a second control loop and compared with the target force value in order to generate a target energization value
- the third signal is fed back in a third control loop and compared with the target energization value in order to control the energization of the actuator
- the sampling frequency of the second control loop is higher than that of the first control loop and lower than that of the third control loop.
- baler produces sidewall arm pressure signals (as represented by the third signals indicating energization of an actuator) at a much higher sampling frequency than is possible in the case of mass signals that can only be generated at most at the completion of each respective bale.
- the sidewall pressure (third sensor) signals may be employed as a high- frequency input to the innermost of three "nested" control loops with the result that the disturbance rejection of the overall control scheme is determined not by the frequency with which bale mass signals can be generated and instead is under the influence of the pressure signals that are relatively high-frequency signals.
- the control loops are employed to generate adjustment signals that are based on the sidewall pressure and hence the pressure in a sidewall adjustment hydraulic system as described in more detail below in order to achieve a target bale weight and hence a target bale density.
- the bale weight measurement signals need to be sampled only at a relatively low frequency since the bale weight signal is relevant only on completion of each bale. Instead any changes in eg. straw mixture leading to unwanted bale density changes are sensed as changes in the force applied by the pistion and/or in the hydraulic sidewall pressure. Adjustments to the plunger force target value and the hydraulic sidewall pressure target value may then be made as a result of said sensed pressure and force respectively.
- the baler of the invention may accurately take account of variations in the characteristics of the straw (or other biomass) as the baler travels over a field.
- the baler of the invention addresses the problem of a change in the straw characteristic leading to the formation of under-weight or over-weight bales relative to a target bale mass.
- the baler of the invention therefore provides clear advantages over the prior art devices described above.
- the actuator (18) is energizable by pressure in a hydraulic circuit
- the third sensor (52) senses pressure in the hydraulic circuit and generates the third signal (MP) indicative thereof.
- This arrangement is advantageous not least because hydraulic control systems provide adequately high forces and sufficient positional accuracy as to be very suitable for modifying the positions of sidewalls of a bale-forming chamber. Furthermore it is well- known in the agricultural machinery art how to configure hydraulic circuits in order to generate accurate pressure measurements.
- sampling frequency of the third control loop is approximately 5 Hz or higher.
- Such a sampling frequency provides a bale density update resolution of approximately one metre when the baler is being towed at 15 km / h. Such a resolution is deemed to be adequate for the requirements of the invention without requiring complex or expensive very high frequency processing circuits.
- the second sensor is or comprises a load cell that detects the force exerted by the piston, the sampling frequency of the second control loop being approximately 0.8 Hz.
- a sampling frequency of 0.8 Hz corresponds to the reciprocations of the plunger of the baler. It follows that in accordance with a preferred embodiment of the invention the force exerted by the plunger on the forming bale is measured, and a signal indicative thereof generated, once for each cycle of the plunger.
- the plunger force is indicative of changes in biomass characteristics. There is however no point in sampling the plunger force more than once per resolution, since only on the forward stroke of the plunger is the plunger force proportional to the density of the biomass that is to be formed into the bale.
- the first sensor is or comprises a load cell disposed to detect the mass of a bale, the sampling frequency of the first control loop being approximately 0.02 Hz or lower.
- the bale discharge comprises a bale chute comprising a pivotable portion on which the mass of a completed bale is supported substantially entirely during discharging, the load cell being disposed to generate a signal that is indicative of the mass of a thus-supported bale acting via the pivotable portion.
- the bale-forming chamber comprises at least one moveable wall portion that is moveable inwardly and/or outwardly to adjust the volume of the interior of the bale- forming chamber, the at least one moveable wall portion and at least one actuator being connected so that the at least one actuator causes movement of at least one moveable wall portion.
- the baler comprises two actuators.
- the actuators are rams.
- the at least one actuator (18) is part of or operatively connected to a hydraulic or pneumatic piston.
- a method for controlling a square baler comprising a biomass feed connected to a bale-forming chamber, a piston that is reciprocable in the bale-forming chamber in order to compact biomass fed into the bale-forming chamber via the biomass feed and form bales and a bale discharge, the dimensions of part of the interior of the bale-forming chamber being adjustable under the influence of at least one actuator the energization of which is controlable; the baler comprising:
- a second sensor for sensing an the force applied by the piston and generating a second signal that is indicative thereof; c) a third sensor for sensing the energization of the actuator and generating a third signal that is indicative thereof, and
- the method comprises the steps of:
- the sampling frequency of the second control loop being higher than that of the first control loop and lower than that of the third control loop.
- Figure 1 is a schematic, vertically sectioned view of a typical square baler
- FIG 2 shows in more detail the bale discharge area of the Figure 1 baler
- FIG 3 is a schematic representation of an hydraulic control circuit for a baler such as that shown in Figures 1 and 2;
- Figure 4 is a schematic representation of a control philosophy, in accordance with the invention, that is suitable for use in the Figures 1 to 3 apparatus, and in accordance with the method and apparatus of the invention.
- FIGS. 1 and 2 show a prior art agricultural baler 10 comprising a frame 12 which is equipped with a biomass feed in the form of a channel 14 that projects forwardly to be hitched to a towing tractor or other vehicle.
- Square bales are formed and tied in a bale-forming chamber 16 in a conventional manner and the bales are discharged from the rear end of the baling chamber 16 onto a discharge in the form of a chute, generally designated 20.
- the chute 20 is formed in two portions, namely a front portion 22 that is pivoted about an axis 24 located at the rear end of the frame 12, and a rear portion 26 that is pivotable relative to the front portion 22 about an axis 28.
- the bale-supporting surfaces of both portions 22 and 26 are coplanar and inclined at an angle of approximately 6 deg. to the horizontal. If dropped from a height onto the ground bales can be damaged and the purpose of the pivoting rear portion 26 is to lower the bales more gently onto the ground.
- bale chute 20 When the weight of a bale rests on the rear portion 26 of the bale chute 20, the latter pivots clockwise, as viewed, to lower its trailing end closer to the ground. In this way the bale slides off the rear portion 26 without any risk of the bale toppling.
- the rear portion 26 of the bale chute is supported on each side of the baler by a chain 30 connected to an elbow joint 32 between two arms 34 and 36 that are secured to one another via an articulated joint. In the raised position of the rear portion 26 shown the two arms 34 and 36 are held in a straight line by the weight of the front section 22 of the chute 20 and by any un-discharged bale which is formed in the bale chamber 16.
- a transducer such as a load cell is straightforwardly disposed to measure the tension in the chain 30 while the rear portion 26 of the chute 20 is in the pivoted position described (ie. when the mass of a bale is completely supported on portion 26). In this position, the rear end of the bale is raised from the front portion 22 of the chute and substantially all its weight is supported by the rear portion 26. Because the bale is tilted, there is minimal contact between the bale being weighed and the succeeding bale acting to push it off the chute 20.
- the combination of these factors increases the accuracy of the measured weight signal, and thus the value of the weight of the bale, compared with prior art devices.
- the chain tension is therefore a reliable indicator of the weight of the bale and there is ample time to take the required measurement because the bale remains supported in the described fashion from the time that its centre of gravity has passed the point where its weight is sufficient to pivot the rear portion into the inclined position, until the instant when the rear end of the bale touches the ground. If several measurements are taken, filtering of electronic signals may be used to minimise errors caused by the chute being jogged up and down as the baler 10 is towed over uneven ground.
- the front portion 22 comprises a first portion 22a that is pivotally attached to the baler frame 12 and a second portion that forms a frame made up of vertical plates 22b and a horizontal plate 22c.
- the second portion 22b, 22c is pivotally attached to the first portion 22a by means of an axis 28 that is only used to move the rear portion of the chute into the transport position as described more in detail in EP1935232.
- the rear portion 26 comprises a pivot frame 26a, which pivots about an axis 128 situated below the support surface of the front portion 22a and rearwards from the leading edge of the rear portion 26, and a weighing table 26b, which is supported on the pivot frame 26a by means of load beams 26c.
- the position of the pivot axis 128 provides a clear separation of the bale once the weighing table 26b pivots in the bale discharging position, so that the bale may be weighed during this suitable weighing timespan.
- the weighing table is formed of a roller conveyor.
- one of the rollers preferably the last roll 30 is provided with a braking device 103 mounted on the roller's axis, and configured to influence the roller's rotational speed by the braking force.
- the baler includes a piston 62 that is reciprocable in the bale-forming chamber 16. Biomass fed via the channel 14 is thereby compacted so as to form bales in the above-described operation of the device 10.
- a sensor 60 is configured to measure the force exerted by the piston 62 in the bale-forming chamber 16 on each forward stroke of the piston as known from for example EP0655190. The dimensions of part of the interior of the bale-forming chamber 16 are adjustable.
- bale-forming chamber 16 two opposed sidewall portions of the bale-forming chamber 16 are moveable under the influence of (in the embodiment shown) a pair of hydraulic actuators 18 comprising rams 72, 74 that are best shown schematically in Figure 3.
- Each ram 72, 74 includes a respective output shaft 76, 78 that is connected to a sidewall portion that is moveable inwardly and outwardly under the influence of the rams in order to decrease and increase the formation pressure acting on the biomass during bale forming operation.
- the rams 72, 74 are connected in an hydraulic circuit 40 ( Figure 3) comprising an oil tank 42, filter 44, pump 46, proportional solenoid valve 48 and deflecting valve 50 connected as shown.
- a hydraulic pressure sensing device is shown schematically as a pressure gauge 52 that is visible in Figure 3, but in practice the sensing device may take a range of possible forms.
- the pressure in the hydraulic circuit 40 may be set when the deflecting valve 50 is in the position shown in Figure 3.
- the deflecting valve 50 may then be operated to its other position in order to de-activate the rams 32, 34 in order to open the moveable sidewalls and relieve the pressure from the bale inside the baleforming chamber.
- An optional feature of the Figure 3 circuit 40 is a one-way valve 54 as shown.
- the pressure gauge 52 lies immediately downstream of the one-way valve 54 and is representative of a sensor or other transducer the purpose of which is to generate a signal MP that is indicative of the pressure in the circuit 40.
- the pressure measurement represented by gauge 52 is also shown schematically in Figure 4, which illustrates the control regime of the square baler 10 of the invention (and hence also illustrates the method of the invention) as a block diagram of a closed loop feedback multivariable control system.
- a target weight TW for each bale is input as a control parameter and compared with the actual weight MW of a completed bale as represented by the output signal of a first sensor in the form of load cell 26c that is as described preferably located in the bale discharge 20.
- the resulting difference signal is fed forwardly via controller 58 which conditions the difference signal for comparison as a target force signal TF with an actual force signal MF generated in a second sensor 60.
- Sensor 60 is configured to measure the force exerted by the piston 62 in the bale-forming chamber 16 on each forward stroke of the piston 62.
- means for setting a target weight value (TW) by the operator for determining a target value for the mass of a bale formed in the baler such means are generally known in the art and could comprise any input device such as for example a touch screen, a keyboard or a potentiometer or encoder for inputting a value to the controller 58 of the baler.
- the signal resulting from this second comparison is further conditioned in controller 58 for comparison as a target pressure signal TP with the measured pressure signal MP generated by a third sensor represented schematically as pressure gauge 52.
- the resulting pressure difference signal is used as a control input (following further conditioning as necessary in controller 58) to the proportional solenoid valve 48 that then causes adjustment of the rams 72, 74 in accordance with operation of the hydraulic circuit 40.
- each part of the control scheme constitutes one of three "nested" control loops involving a feedback path.
- the innermost loop of the control scheme being that represented by pressure measurements, is the highest frequency part.
- the frequency of sampling in this part of the control circuit is 5 Hz or higher.
- Other sampling frequencies however are possible within the scope of the invention.
- the force measurement carried out by second sensor 60 takes place at a frequency of approximately 0.8 Hz corresponding to reciprocation of the piston of the bale-forming chamber 16. Sensing of the mass of an entire bale in the bale discharge 20 takes place for example approximately one every 50 seconds or at a frequency of 0.02 Hz.
- the apparatus and method of the invention increase the precision of the weight of the resulting bale and automatically take account of biomass parameter variations as described.
- the circuit and apparatus of the invention therefore assure that the target weight TW is attained regardless of such characteristic changes, and using apparatus that is easy to embody in relatively simple (from the processing point of view) machines such as square balers. Overall therefore the apparatus and method of the invention offer considerable advantages compared to the prior art.
