Definitions

  • the invention relates to a lifting and tipping device for emptying containers into the opening of a collecting container, in particular for emptying garbage containers into the collecting container of a garbage truck, which has a substantially triangular gripping and carrying plate which interacts with a receptacle provided in the edge region of the container to be emptied has, which is arranged with its tip pointing upwards at the free end of an extendable and / or pivotable gripping arm and whose upper triangular sides form sloping, sloping gripping surfaces towards the side facing away from the container to be accommodated.
  • the substantially triangular gripping and carrying plate is arranged to be pivotable to a limited extent about its vertical central axis on a gripping arm, with the limited lowering of the gripping and carrying plate under the load of the received container Gripping and support plate is pivoted into a normal position about its vertical central axis by means of a cam guide and is held in this position.
  • This limited swiveling of the gripping and carrying plate has proven to be too small for many practical purposes, in order to be able to accommodate containers provided for emptying in a more or less inclined position.
  • the gripping and carrying plate is connected to the gripping arm with limited movement via at least one joint, and for each of the joints contained in the connection between the gripping arm and the gripping and carrying plate, an adjusting device for the gripping and Support plate is provided in a normal starting position with respect to the gripping arm, which is defined for the emptying process.
  • such joints can be provided adjacent to the gripping and carrying plate or directly on the gripping and carrying plate, so that the gripping and carrying plate adapts as far as possible to this position when it is brought up to a container to be picked up in order to hold the container after being picked up to move to the normal starting position defined for the emptying process.
  • the gripping arm has a bracket, which can be rotated about an axis that is vertical in the initial position, as a joint connection with the gripping and carrying plate.
  • This enables the gripping and carrying plate to have a limited pivoting movement about an essentially vertical axis.
  • This possibility of a limited swiveling movement around a vertical axis alone offers secure picking up of inclined containers and the safe transfer of the gripping and carrying plate with the picked up container into the normal starting position for the emptying process.
  • a horizontally arranged cross member can be attached to the console, on which at least one gripping and supporting plate is provided at a lateral distance from the axis of rotation of the console.
  • the gripping and carrying plate is additionally given the possibility of a limited translational movement, as a result of which the secure reception of containers placed at an angle is made even easier.
  • This measure can preferably be further developed and improved to the extent that the cross member is designed with respect to the axis of rotation of the console in the manner of a two-armed lever and carries a gripping and carrier plate on each of its lever arms.
  • the crossmember designed in the manner of a two-armed lever, forms, together with the two gripping and carrying plates, a type of lever system that is just as good for emptying larger containers that are equipped with two receiving pockets as for simultaneously picking up and emptying two side by side for emptying provided smaller container is suitable.
  • the cross member with the two gripping and supporting plates adjusts to any inclination of the larger container.
  • the lever system formed by the cross member with the gripping and carrying plates adjusts to the given mutual position of the two containers by the pivoting and carrying plate first striking the respective container when the device is pushed forward of the cross member on the console until the second gripping and carrying plate has come into contact with the second container.
  • the finished insertion and receiving of the containers is then achieved by the shape of the gripping and carrying plates, both with a larger container with two receiving pockets and with two smaller containers with one receiving pocket each.
  • the return of the console and possibly the cross member in the normal starting position defined for the emptying process can be significantly improved and facilitated in that the limited rotatable console contains a reset device with which the console can also be locked against rotation in its middle rotational position.
  • a reset device for the formation of such a reset device, for example, that in addition to the limited rotatable console at least one effective between the gripping and support plate and the gripping arm, for example designed as a spring bar or as a tension spring for resetting the gripping and supporting plate in their for the Emptying process defined normal starting position determining middle position is provided.
  • the bracket which can be rotated to a limited extent, contains at least one torsion spring for returning to its central rotational position which determines the normal starting position of the gripping and carrying plate, which is determined for the emptying process.
  • the gripping and carrying plate can be locked in their normal starting position, which is defined for the emptying process, in that the resetting device has an engagement device which can be actuated against the force of a carrier spring by the load of a received container.
  • the blocking takes place together with the transfer of the gripper arm into its normal starting position for the emptying process, in particular when the gripping arm is folded into this normal starting position.
  • the gripper arm can be attached to a swivel arm in a normal starting position that is fixed for the emptying process, between the gripper arm and the swivel arm a control element responsive to the fold-in position of the gripper arm with respect to the swivel arm, for example a hydraulic piston cylinder, can be inserted, and the reset device the console have an engagement device which can be actuated by means of the control element in such a way that when the gripper arm is folded in the normal starting position, the reset device blocks the console in its central rotational position.
  • a control element responsive to the fold-in position of the gripper arm with respect to the swivel arm for example a hydraulic piston cylinder
  • the resetting device and the engagement device can be tuned in such a way that the mobility in the console is increasingly reduced when the gripper arm is folded in, namely between maximum mobility when the gripper arm is folded outwards and completely fixed when the gripper arm is folded down.
  • the reset device has a hydraulic actuating and blocking cylinder which engages via a pivoting lever on the console and is pivotally attached to the device frame about a vertical axis and which is connected to the hydraulic control and operating system the pressure medium motors for lifting and tipping the device is connected.
  • the hydraulic actuating and blocking cylinder can contain a differential control piston which is constantly acted upon on both sides by hydraulic pressure medium from the control and operating system of the pressure medium motors, the end position assigned to the larger piston surface defining the normal starting position of the gripping and carrying plate with respect to the gripping arm.
  • the invention also offers a second basic possibility for the articulated attachment of the gripping and carrying plate to the gripping arm in that a substantially horizontally extending cross member is provided for the gripping and carrying plate on the gripping arm and the gripping and carrying plate on the one hand have at least an articulated lever and return spring are movably connected to the crossmember and, on the other hand, are guided with respect to the crossmember by means of at least one cam guide for simultaneous vertical displacement movement and pivoting movement.
  • the functional interaction of the articulated lever with the return spring and the cam guide of the gripping and carrying plate gives an additional adjustment movement with which it can oppose a container to be emptied with the tip of its triangular shape.
  • the triangular tip of the gripping and carrying plate in its position inclined towards the container to be emptied, is suitable for engaging at virtually any point in the receptacle provided on the container. Even if the triangular tip of the gripping and carrying plate is only placed at one or the other outer end of the receptacle provided on the container to be emptied, a slight lifting of the lifting and tilting device is sufficient to securely hold the container with its receptacle in a defined position to slide over and onto the gripping and carrying plate. When the load is transferred from the container to be emptied to the gripping and carrying plate, this is transferred to the defined working position for emptying the container due to its movable attachment and its cam guide on the cross member.
  • This second basic possibility can be used in combination or in combination with the first basic possibility explained above, so that there is practically universal mobility of the gripping and supporting plate with respect to the gripping arm, while nevertheless reliably transferring the container to be emptied into the normal starting position is guaranteed for the emptying process.
  • the cam guide can have a wedge-shaped or fork-shaped guide cam attached to the cross member and one in or on the gripping and Support plate attached cam grip included.
  • the cam guide should be coordinated with its parts so that when the gripping and carrying plate is completely lowered, a secure non-positive connection for the transfer of the load of the container received to the cross member and a firmly defined position or location of the gripping and carrying plate on Cross members are guaranteed.
  • This can be achieved with a fork-shaped design of the guide cam, for example, in that the guide cam has a wedge-shaped guide finder and a limiting finger, the distance between these two fingers decreasing from top to bottom and merging into a limiting recess at the lower end.
  • a lower guide limit for the cam gripper roller can be provided in an analogous manner in order to form the non-positive connection required for the load transfer to the cross member.
  • the guide cam can preferably be assigned an alignment edge as a system for aligning the gripping and supporting plate in its lowest position in the vertical position or with a predetermined angle of inclination, in order to ensure a defined normal starting position for the actual emptying process. With this alignment edge, together with the lower movement limitation of the cam tapping roller, a type of wedging engagement can be formed, which represents an additional improvement in the frictional connection between the gripping and carrying plate and the cross member.
  • the cam tapping roller can be mounted in two mutually spaced strips or sheets on the gripping and carrying plate, the Distance between the two strips or sheets forms a receiving and guide space for the guide cam.
  • the return spring is advisable to provide the return spring as a tension spring, the line of action of which with respect to the position of the gripping and carrying plate offset of the cross member and runs at a distance from the pivot points of the articulated lever.
  • a secure load transfer from the container to the gripping and carrying plate can be improved in that the gripping and receiving plate, in the continuation of their gripping surfaces on both sides, each have an essentially ear-shaped side support element with an upper bearing surface for the wall of an Container for the gripping and carrying plate provided receiving pocket.
  • These additional, essentially ear-shaped side support elements ensure a uniform load transfer from the received container to the gripping and carrying plate, so that these in turn result in a uniform load transfer to the gripping arm or to the cross member, be it directly or indirectly via articulated lever with return spring and cam arrangement .
  • the receiving claw 11 of the receiving device 10 is provided with a gripping and carrying plate 12, which is essentially triangular in shape with an upward, rounded triangular tip 13, the gripping and carrying plate 12 is hollow in the example shown and has one of the substantially flat abutment wall 14 to be placed opposite the container, a rear wall 15 facing away from the container and a gripping wall 16 connecting the abutment wall 14 and the rear wall 15 at their upper edges and covering the gripping and carrying plate 12.

  • the cross member 21a, 21b is fixedly mounted on a bracket 36 which can be rotated about the axis 41.
  • this bracket 36 is in turn rotatably mounted on the two mounting brackets 53 of the gripping arm 37 by means of a bearing and guide pin 42.
  • the carrier bush 43 of the console 36 is fixedly attached to a carrier plate 71, which is rotatably mounted about the axis 41 on the bearing and guide pin 42 and has a pivot lever 72 as an extension on which the piston rod 76 of the hydraulic actuating and blocking cylinder 75 pivots.
  • the second end of the hydraulic actuating and blocking cylinder 75 is articulated on the device frame so as to be pivotable about a vertical axis 61.
  • the actuating and blocking cylinder 75 contains a differential double piston 77, which is formed from a plunger-like front piston part 78, which is fixedly connected to the piston rod 76, and an annular, but sealed behind the piston part 78 on the piston rod 76 axially displaceable ring piston 79. Accordingly, the interior of the actuating and blocking cylinder 75 is formed with two interior parts, which are separated from one another by a shoulder 80, namely a narrower interior part 81 in which the plunger-like front piston part 78 runs and a further interior part 82 in which the annular piston part 79 is running.
  • the inner part 81 lying in front of the plunger-like piston part 78 is provided with a pressure medium connection 83, while the inner part 82 behind the annular piston part 79 is provided with a pressure medium connection 84.
  • a further pressure medium connection 85 In the area of the shoulder 80 there is a further pressure medium connection 85.
  • the pressure medium connections 83 and 84 are connected to one another via a pressure medium line 86 and, in this parallel connection, are connected to the pressure medium lines of the hydraulic control and operating system of the device, via which those intended for lifting and tipping are connected Pressure medium motors of the device are charged with hydraulic pressure medium.
  • the pressure medium inlet 85 provided in the area of the shoulder 80 is on the low pressure side of the hydraulic control and operating system, for example, the pressure medium reservoir, connected, or only opened to the outside air at all.
  • the annular piston part 79 has an end face F1 to be acted upon by its pressure medium chamber 82 and the piston-like piston part 78 has an end face F2 to be acted upon by its pressure medium chamber 81.
  • the end face F1 of the annular piston part 79 is considerably larger than the end face F2 of the piston part 78, for example twice as large.
  • the operation of the reset device provided in the example of FIGS. 10 to 14 is as follows: When the receiving device 10 is lowered, the pressure medium lines leading to the pressure medium motors for lifting and tipping the container to be emptied are largely relieved of pressure.
  • the piston parts 78 and 79 can therefore be moved by acting on the piston rod 76 with relatively little force in the interior of the actuating and blocking cylinder 75, the hydraulic pressure medium present in the interior parts 81 and 82 damping more or less only this displacement movement.
  • the cross member 21a, 21b with the gripping and carrying plates 12 mounted thereon can pivot relative to the respective container or containers by pivoting on the console 36 either that shown in FIG 12 arrows 73 or arrows 74 shown in FIG. 12 pivot in order to adapt the position of the gripping and carrying plates 12 to the wall of the respective container or containers. If the cross member 21a, 21b is pivoted in the direction of the arrows 73, the piston rod 76 is displaced towards the inside of the actuating and blocking cylinder 75, the plunger-like front piston part 78 being displaced in its interior part 81, as shown in FIG. 13 is.
  • the annular piston part 79 is thereby pressed against the shoulder 80, while the plunger-like piston part 78 is pushed from its position shown in FIG. 13 up to the annular piston part 79.
  • the cross member 21a, 21b is pivoted back into the normal starting position for the emptying process. Since the end face F1 of the annular piston part 79 is substantially larger than the end face F2 of the plunger-like piston part 78, the plunger-like piston part 78 remains on the annular piston part 79 and this in turn remains on the shoulder 80.
  • the reset device is thus blocked in this Koblenposition and thus holds the receiving device blocked in the normal starting position for the emptying process.
  • the hydraulic control and operating system of the device for lifting and tilting a container to be emptied is put into operation in order to include the corresponding pressure medium motors to feed hydraulic pressure medium, so at the same time in the interior parts 81 and 82 of the actuating and blocking cylinder 85 increased, but the same pressure built up. Since the end face F1 of the annular piston part 79 is pushed much larger than the end face F2 of the plunger-like piston part of the pressure medium present in the interior part 81 into a position in which the annular piston part 79 rests on the shoulder 80. The plunger-like piston part 78 is pressed against the annular piston part 79 by the pressure of the hydraulic pressure medium in the interior part 81, but cannot move it away from the system against the shoulder 80. Thus, starting from the piston position according to FIG. 14, the cross member 21a, 21b is reset and pivoted back into the normal starting position for the emptying process and blocking in the normal starting position.
