Definitions

  • the invention relates to a pendulum arm for a roller compactor for compacting waste materials, with the features of the preamble of claim 1.
  • FIG. 1 shows a waste compaction device in which an approximately cylindrical container is provided, with an axis arranged in its center.
  • a driven roller body is arranged perpendicular to the axis. It is driven by a rotary motion and runs around the axis in a circular path within the container.
  • roller compactor was first presented by the applicant in the DE 30 23 508 C1 As described, a roller, guided at the end of a pivoting arm, compacts the waste. The roller's rotation redistributes the surface layers of waste within the container, allowing them to move lengthwise. This roller compactor is particularly well-suited for dry waste with large voids, such as bulky waste or wooden crates. The container's capacity is significantly increased compared to uncompacted waste.
  • the support arm is positioned on a tripod outside the container to utilize the entire container volume for waste.
  • This also makes it possible to use a stationary roller compactor with multiple interchangeable containers.
  • a two-part articulated arm is provided. The first part of the articulated arm, connected to the tripod, can be raised by an actuator, such as a hydraulic cylinder, to lift the roller out of the container.
  • a pendulum arm is attached to the other end of the first part via a pivot joint, and the rotatable roller is mounted at the end of the pendulum arm. The compaction is achieved solely by virtue of its own weight, i.e., without any contact pressure from the arm.
  • the object of the invention is therefore to improve a pendulum arm of the type mentioned above in such a way that the torsional loads on the pendulum arm and in particular on its upper pivot bearing are reduced.
  • This pendulum arm is a self-contained unit, making it ideal for retrofitting existing roller compactors. Together with a tripod and a support arm (at least one-piece), it forms a complete roller compactor.
  • All embodiments of the invention have in common that between the transmission holder element and the adjoining sections of the pendulum arm or within a pendulum arm divided into several parts, at least one torsional compensation coupling is arranged, which comprises at least two coupling element components that can be coupled together.
  • the basic principle of the invention is based on the fact that the coupling elements are freely rotatable over a small angle in both possible pivot directions and do not collide hard with each other at the end of the pivot range. This is achieved, firstly, by the coupling elements having effective stop surfaces around the compensating axis in both possible pivot directions, and secondly, by the presence of at least one elastomeric stop element between the contacting stop surfaces of the coupling elements.
  • Effective means that the pivot angle is limited by the contacting stop surfaces and that direct contact between, in particular, metallic stop surfaces is prevented.
  • the position and design of the elastomeric stop element can vary. It can be an elastomeric coating or covering of one or both stop surfaces, or it can be a separate element positioned between the stop surfaces.
  • the invention therefore does not provide for an element such as a torsion spring that is twisted, or another spring element that is tensioned directly at the beginning of the twisting.
  • the coupling components are, in particular, flange-like plates aligned parallel to each other. Preferably, they have at least one recess in the center to allow electrical, pneumatic, or hydraulic lines to pass through the torsional coupling from the pendulum arm to the transmission mounting element or to a further section of the pendulum arm.
  • the coupling components can be pivoted relative to each other with respect to a compensating axis extending parallel to the longitudinal direction of the pendulum arm, with the pivot angle being positively limited in each case. At least when the end ranges of the possible pivot angle are reached, and possibly even earlier during the pivoting movement, at least one spring element and/or an elastomeric stop element arranged between the coupling components is deformed, so that torque peaks are mitigated and the torsional load on the pendulum arm and its bearing on the support arm is reduced.
  • a coupling component has an axle stub which is aligned parallel to or in line with the longitudinal axis of the pendulum arm and which engages in a bearing bushing on the other coupling component and is positively secured there in such a way that tensile and compressive forces as well as bending moments can be transmitted via it.
  • At least one protruding element on an elastomeric stop element engages in a recess on the other coupling component, so that the possible swivel angle is positively limited.
  • one of the coupling components has brackets for elastomeric stop elements on both sides of a central axis.
  • at least one pair of elastomeric stop elements can be arranged above and below the axis, with a gap-like space between each pair.
  • projecting, wing-like drive elements are provided above and/or below an axis receptacle. The drive element initially moves freely in the space between the paired stop elements and then, at the end of the intended pivoting movement, abuts one of the stop elements.
  • At least one radially projecting, wing-like drive element is attached to the central axis, and at least two elastomeric stop elements are spaced apart from each other on the other coupling component, which has the bearing bushing for the axis.
  • the drive element initially moves freely in the space between the stop elements and then, at the end of the intended pivoting movement, abuts one of the stop elements.
  • a torsional compensation coupling is constructed in which the swivel angle is limited by the fact that both coupling elements each have an X-shaped rib structure on their facing sides.
  • the X-shaped rib structure of one coupling element is narrower than the X-shaped rib structure of the other coupling element and projects further axially forward. This allows the rib structures to interlock positively and remain pivotable relative to each other until the ribs touch.
  • Elastomeric stop elements are attached at the contact points between the rib structures to decelerate and then stop the movement when the end position is reached.
  • a pendulum bearing is formed off-center between the coupling elements via a common axis, particularly in the upper or lower edge region.
  • a guide pin is also provided in the vertically opposite lower or upper edge region of one coupling element, which engages in a circular arc-shaped guide groove on the other coupling element.
  • the torsional compensation coupling has flange-like coupling elements which are pivotably coupled to each other via a bearing bushing on one coupling element and an axle engaging therein on the other coupling element.
  • a stop element is inserted between several corner regions of the rectangular flanges of the coupling elements, by which the coupling elements are articulated to each other.
  • the pivot angle between the coupling elements is positively limited by guide pins on one coupling element that engage in guide grooves on the other coupling element.
  • At least one limit switch such as an inductive proximity switch, is provided in the torsional compensation coupling. which may already give a signal for an emergency shutdown of the roller drive when the end position of the swivel movement is reached, but at the latest when there is strong compression of the spring and/or stop elements provided in the end positions.
  • FIG. 1 shows a roller compactor 100 for compacting waste materials 203.
  • a container 200 has a front end wall 201 and a rear end wall 202. The line in the container 200 indicates the top of a load of waste materials 203. Behind the rear end wall 202, a tripod 12 of the roller compactor 100 is arranged, which extends with forward-projecting skids to below the bottom of the container 200 to improve support.
  • a support arm 10 is connected to the tripod 12 via a joint 15.
  • a pendulum arm 20 is connected via another joint 11. No actuators are provided between the support arm 10 and the pendulum arm 20, so that the pendulum arm 20 can pivot freely about the joint 11.
  • a gear mounting element is attached, which includes, among other things, bearing elements and a gearbox for a roller unit 30 to drive a roller 31.
  • a lifting cylinder (not shown) is provided between the stand 12 and the support arm 10 as an actuator to raise and lower the support arm 10. As the support arm 10 is raised and lowered, the joint 11 moves along a circular arc path 17.
  • Fig. 1 Near the end walls 201 and 202, the end of the pendulum arm 20 with the roller unit 30 is shown again. These are the end positions that the roller unit 30 can reach by moving the support arm 10 relative to the stand 12, thereby moving the axis of the joint 11 along the circular path 17. No contact force is exerted via the support arm 10; that is, the compaction of the waste material 203 in the container 200 occurs solely due to the rotation and mass of the roller unit 30. as well as the sharp-edged web elements attached to the outer shell of the rollers 31 for conveying and crushing the waste materials.
