Definitions

  • the present invention relates to a press for compacting material of metal scrap, metal waste, general waste or other material, which does not necessarily have to consist of or even comprise metal, in which the material is formed into bales by means of compaction.
  • the present invention further relates to a method of compacting material of metal scrap, metal waste or general waste or other material, which does not necessarily have to consist of or even comprise metal.
  • Such presses are for example known from METSO Recycling, for example the METSO ETAPRESS®, in which the material can be formed into bales.
  • a similar press is described, for example, in DE 102 58 660 A1 and in EP 1 056 589 B1 .
  • Further presses are known, for example cover presses where the compaction takes place predominantly along only two directions more or less in a plane whilst the material to be compacted is not significantly compacted along the third, perpendicular direction.
  • cover presses where the compaction takes place predominantly along only two directions more or less in a plane whilst the material to be compacted is not significantly compacted along the third, perpendicular direction.
  • the metal scrap or waste is compacted in a compacting chamber and, after the compaction has been completed, discharged from the compacting chamber by means of a discharging arrangement, usually comprising a door arrangement for selectively opening, and closing the compacting chamber.
  • hydraulic pumps used in the known presses are optimized for supplying hydraulic fluid at a high flow rate to the main hydraulic cylinders which are used for compacting the material.
  • These main cylinders are massive and require very high flow rates for compacting the material and to minimize the cycle times.
  • usually multiple, in particular double, pumps are used for providing the flow rate of the hydraulic fluid.
  • auxiliary cylinders are typically used for opening or closing a door, e. g. of a discharging arrangement.
  • An object of the invention is to increase the overall efficiency of presses of the generic type described in the introduction with optimally combined sequences of functions, both the coordinated operation of the different steps and the optimization of the kinematic sequence of the functional elements and the driving forces.
  • an object of the present invention is to increase the overall efficiency of presses of the generic type described as the field of the invention with respect to an actuation of the movable parts of the press, in particular the compacting surface or surfaces of the press and a door arrangement.
  • a press for compacting material of metal scrap, metal waste, general waste or other material which does not necessarily have to consist of or even comprise metal
  • which press comprises a compacting chamber having at least one movable compaction surface configured for compaction of the material, and a door arrangement configured for selectively opening the compacting chamber for removal of the compacted material; a hydraulic pressure actuation system configured for acting upon said at least one movable compaction surface; and a door actuator configured for acting upon said door arrangement for opening and closing of the door arrangement.
  • said door actuator is an electric drive.
  • the door actuator as an electric drive, many advantages may be provided, e.g. the power consumption may be reduced, a simplified design of the pressure actuation system and the door actuator may be enabled, the time for reacting to any malfunctions of the overall system may be shortened, the kinematic sequence of the functional elements and the driving forces to be set up may be optimized to decrease a cycle time of the material compaction to increase the availability and efficiency of the press and/or to decrease the costs by reducing flow, pump and valve sizes. A more productive machine which can be used with lower operation costs is thereby provided.
  • the hydraulic pump or multiple hydraulic pumps for the main hydraulic cylinders may continue to run at their optimized power providing the high fluid flow rate required by the main hydraulic cylinders, while the door actuator is operated in a reliable and controlled way.
  • separate circuits for controlling and actuating the door arrangement, on the one hand, and the compaction surface or compaction surfaces, on the other hand are provided which facilitate the overall configuration and allows the operation of the press to be more efficient.
  • the press comprises an obstruction sensor which is configured for sensing if opening and/or closing of the door arrangement is obstructed.
  • an obstruction can generate a significant increase in the force required for opening or closing the door.
  • the obstruction can also be a partial obstruction so that opening or closing of the door is partially possible and partially requires an unusually high amount of force.
  • Such a sensor may be provided as part of the electric drive where it is detected whether the electric drive is successful in actuating the door arrangement or not. For example, the electric current and/or voltage consumed by the electric drive can be monitored for deriving information as to its operating state.
  • an operator can be alerted by generally known means such as a warning lamp, warning horn or other means, and the operation of the press can be paused.
  • any obstruction of the door arrangement can be quickly sensed and be reported to an operator.
  • the obstruction is aggravated by applying a high force to the door arrangement which could result in more difficulties when removing of the obstruction.
  • the press can both more efficiently and more reliably and securely be operated.
  • an electric drive also generally allows for much easier and faster reacting to an obstruction of the door arrangement because the response of an electric drive is significantly faster and easier to obtain than a response from a hydraulic system. Even if a detecting time for detecting an obstruction of the door arrangement would not be shorter when the electric drive is used, at least the reaction time, i. e. the period required for shutting down a respective hydraulic valve, is longer for a hydraulic valve than the reaction time of an electric system. This results in the additional advantage of this preferred embodiment that an obstruction of the door arrangement can be detected and handled within a shorter period of time. Accordingly, an obstruction of the door can more easily be handled than when a hydraulic device is used.
  • said compacting chamber has at least two movable compaction surfaces.
  • said compacting chamber has at least three movable compaction surfaces.
  • Multiple compaction surfaces enables a higher degree of compaction if compared to presses with fewer compaction surfaces.
  • Multiple compaction surfaces can, be provided in an orthogonal relationship to each other. However, this is only optional and the compaction surfaces can also be arranged with respect to each other at other angles.
  • a method for compacting material of metal scrap, metal waste, general waste or other material which does not necessarily have to consist of or even comprise metal.
  • said method comprises the following steps:
  • said method further comprises actuating a second movable compaction surface of said compacting chamber by a second pressure actuator to move said second movable compaction surface to compact said material against said first opposite surface or a second opposite surface within said compacting chamber.
  • said method further comprises actuating a third movable compaction surface of said compacting chamber by a third pressure actuator to move said third movable compaction surface to compact said material to be compacted against said first opposite surface, said second opposite surface, or a third opposite surface within said compacting chamber.
  • movable compaction surface means any surface of the press which can move towards the material for compaction thereof.
  • compaction is to be understood as equivalent to “compression”.
  • the surface movement may be a pivotable movement, such as a swivelling or pivotable movement of a press cover; or a linear movement of a compaction surface within a compacting chamber.
  • movable compaction surface means any of these surfaces of a press cover and a movable wall surface within a compacting chamber.
  • opposite surface means any surface towards which the movable compaction surface moves and against which the movable compaction surface compacts the material to be compacted.
  • door arrangement means any arrangement which is suitable for opening and closing an opening of a compacting chamber for discharging of compacted material out of the compacting chamber. It may particularly be a door arrangement for opening and closing to enable discharging of the compacted material by pushing the compacted material out through the door arrangement.
  • the term "press for compacting material of metal scrap or waste” means a press which is objectively suitable for compacting material of metal scrap, metal waste, general waste or other material, which does not necessarily have to consist of or even comprise metal.
  • the term "method for compacting material of metal scrap or waste” as used herein means a method where material of metal scrap, metal waste, general waste or other material, which does not necessarily have to consist of or even comprise metal, is compacted by the method.
  • the Figures show the embodiment of a press 1 for compacting material.
  • the press 1 has a compacting chamber 2 (seen in more detail in Figs. 2 , 3 and 4 ) with an inlet opening 3 through which the material M to be compacted is charged into the compacting chamber 2.
  • the compacting chamber 2 has a bottom surface 4 (as seen in Figs.
  • Said door arrangement 10 has a door actuator 14, which is provided as an electric drive.
  • Examples of an electric drive may be a ball screw drive with an electric motor and/or an integrated servo hydraulic driven cylinder.
  • Said door arrangement 10 is arranged to be opened and closed by the door actuator 14.
  • a rack and pinion drive with an electric motor is preferred. It has proven to be particularly well suited so as to combine a transmission of the forces necessary to hold the door shut against compaction forces, with adequate speed in opening and closing the door and sufficient robustness upon obstruction of the door arrangement by scrap, in particular metal scrap.
  • the rack is preferably mounted to the door and the pinion is on the shaft of the electric motor.
  • the pinion is a helical gear wheel which means that the edges of its teeth are not parallel to the axis of rotation of the pinion, but inclined relative to this axis of rotation. More preferably, the angle of inclination is a value between 15° and 20°. Since the gear is curved, this inclination will result in the tooth shape being the segment of a helix.
  • the electric drive includes a gear between the electric motor and the pinion which is so arranged that the longitudinal axis of the electric motor and the axis of rotation of the pinion are at a substantially right angle to one another. This permits to orient the longitudinal axis of the motor for it to be substantially parallel to the rack.
  • each surface moves from one first position to a second position, wherein the distances between the movable compaction surface 5, 7 and 9 and the corresponding opposite surfaces 6, 8 respectively are larger when the movable compaction surfaces 5, 7, and 9 are in the first position than when the movable compaction surfaces 5, 7 and 9 are in the second position.
  • This also applies to a movable compaction surface when any of the movable compaction surfaces is arranged for a pivotable movement in correlation to the respective opposite surface thereof.
  • the second position is not necessarily fixed.
  • the second position can be determined by a predefined position relative to the first position or to the respective opposite surface.
  • the second position can be determined by a predefined resistance, force or pressure, against which the respective movable surface presses. In this latter case, depending on the material M to be compacted, the second position can individually vary for one or more of the movable surfaces.
  • the pressure actuators 11, 12 and 13 are all hydraulic actuators, while the door actuator 14 is an electric drive, which is individually controlled separate from the hydraulic pressure actuation system.
  • the means for actuating the compaction surfaces, on the one hand which must apply huge forces to the material M and, at the required short cycle times, require very high fluid flow rates of hydraulic fluid, and the means for actuating the door arrangement, on the other hand, are de-coupled. This allows for selectively and independently actuating the compaction surfaces and the door arrangement, each at an optimal environment, in particular forces and speeds.
  • Cycles of material handling are performed during the method of compacting material.
  • all three movable compaction surfaces are placed in a respective first position withdrawn from corresponding opposite surfaces.
  • the compacting chamber 2 can be reached via the inlet opening 3.
  • material to be compacted may be charged into the compacting chamber 2 via the inlet opening 3.
  • the material M is placed on the bottom surface 4.
  • the first movable compaction surface 5 of said compacting chamber 2 is actuated to move from its first position to its second position, and, when moving the first movable surface 5, the material M is moved and compacted against the first opposite surface 6 of the compacting chamber 2.
  • the second movable compaction surface 7 of said compacting chamber 3 is actuated to move from its first position to its second position, and when moving the second movable surface 7 the material M is moved and compacted against the second opposite surface 8 of the compacting chamber 2, which in the shown embodiment is the same as the bottom surface 4.
  • the third movable compaction surface 9 of said compacting chamber 2 is actuated to move from its first position to its second position, and, when moving the third movable surface 9, the material M is moved and compacted against the third opposite surface 10, which in this embodiment is the door arrangement 10.
  • the door arrangement 10 of the compacting chamber is actuated to be opened, and the second movable compaction surface 7 is actuated to withdraw from its second position back to its first position.
  • said third movable compaction surface 9 is actuated to move from its second position to a third position thereof to move and, at least partially, discharge the compacted material out of the press 1.
  • the third movable compaction surface 9 is actuated to withdraw from its third position and back to its first position, and the first pressure actuator 11 actuates the first movable compaction surface 5 to withdraw from its second position back to its first position.
  • the first movable compaction surface 5 is withdrawn from its second to its first position either before or during the withdrawal of the third movable compaction surface 9 from its third back to its first position.
  • the door actuator 14 is actuated to close the door arrangement 10.
