Definitions
- the invention relates to a method for emptying garbage containers according to the preamble of claim 1.
- the invention also relates to a device according to the preamble of claim 8 and claim 16.
- Such lift and tilt devices are known for example from EP 0 010 719 or EP 0 423 682.
- small waste containers eg with a capacity of 240 l
- Both lifting and tipping devices can also be connected hydraulically and / or mechanically to form a so-called combination operation in order to empty large waste containers (for example with a capacity of 1.1 m 3 ).
- the receiving devices of the single-stroke tilting devices are designed for the joint detection of such a large waste container.
- a single tilting device as a rule only a single pressure medium motor is provided, while in the case of a single lifting and tilting device a pressure medium motor is usually provided for the lifting phase and a pressure medium motor for the tilting process.
- the respective pressure medium motors are simultaneously pressurized by a common pump.
- the emptying process in the case of large waste containers must run more slowly during the emptying process than is permitted for the small waste containers.
- a much greater pressure must be applied in the pump or the pressure medium system than is necessary when emptying the small waste containers.
- the pump output must be adapted to these requirements.
- the pump for emptying large waste containers must deliver a correspondingly large pressure Pmax because of the large weight, the volume flow Q ⁇ Qmax in the pressure medium motor being lower in comparison to individual operation.
- a large volume flow Qmax at a lower pressure P ⁇ Pmax must be made available.
- the object of the invention is a method with which the emptying of small and large garbage containers can be carried out as before without loss of container weight and emptying speed with better utilization of the performance of the pump or the pressure medium system. It is also an object of the invention to modify the device so that a less powerful pump can be used.
- pump is understood to mean the pressure medium pump associated with an individual lifting / tilting device or individual tilting device or the pump common to both individual lifting / tilting devices or individual tilting devices.
- Lmax Q • P
- the pressure medium motor - this can be the tilting pressure medium motor or a pressure medium motor for lifting and tipping - is preferably not only fed by the pump but also additionally by a reservoir, the excess pressure preferably being used to push the pressure medium out of the reservoir.
- This additional pressure medium made available from the reservoir increases the volume flow to the level required for emptying small waste containers.
- the pressure medium motor When emptying small waste containers, the pressure medium motor is preferably acted upon by a volume flow Q D , which is derived from that of volume flow Q supplied to the pump and a volume flow Q R supplied by the reservoir is formed.
- This first alternative in which work is carried out at high pressure Pmax, has the advantage that less pressure medium has to be pumped overall than if the output is based on the high volume flow.
- the line cross-sections can therefore be made smaller and smaller units are sufficient for cooling the pressure medium. Smaller pumps have the additional advantage that the noise level is significantly lower.
- the pump output is based on the volume flow Qmax, that is to say on the power requirement for emptying small waste containers.
- the volume flow is too high for this and the force required is too low.
- an additional measure must be taken in the pressure medium system in order to convert the pressure and volume flow values of the pump accordingly.
- the second alternative in which the pump output is designed for a high volumetric flow, has advantages in that the components have a longer service life because of the lower pressure .
- Both embodiments can be carried out with side-by-side lifting and tipping devices, the solution according to the invention being independent of whether the single lifting and tipping device or the single tilting device can be operated independently of one another.
- the individual lifting and tipping devices or individual tipping devices are generally only connected hydraulically when emptying large waste containers. It is also possible to provide both individual lifting and tipping devices or single tipping devices with a continuous receiving comb, with which both large waste containers and one or two small waste containers can be emptied.
- the lifting phase it does not matter whether large waste containers or small waste containers are emptied.
- the decisive factor is the tipping-in phase, which can be carried out faster with small waste containers than with large waste containers. It is also possible to have small waste containers and large waste containers respectively to be lifted just as quickly and to be delayed by the solutions according to the invention in the case of large waste containers or to be accelerated in the case of small waste containers.
- a2 is characterized in that, in addition to the pump, at least one additional pressure medium supplying reservoir is provided, which is used to empty small waste containers and the pressure medium motor - tilting pressure medium motor or pressure medium motor for lifting and tipping - is switchable.
- the rod side of the pressure medium motor preferably forms the reservoir.
- the connection of the rod side of the pressure medium motor is known per se (see Backe and Murrenhoff, Inst, for fluid power drives and controls of the Rheinisch Westbische Technische Hochhoff Aachen, 10th edition 1994, pages 318-320) and is referred to as rapid traverse with differential cylinder.
- this circuit for lifting and tipping devices or tipping devices for emptying garbage containers, or to use this circuit for converting high pressure into a high volume flow for the emptying process of small garbage containers.
- the rod side is advantageously connected to the piston side of the pressure medium motor via a connecting line.
- the rod of the pressure medium motor can be connected to the piston of an auxiliary pressure medium motor, the pressure side of which forms the reservoir.
- the pressure side of the auxiliary pressure medium motor is also connected to the piston side of the pressure medium motor via a connecting line in which a changeover valve is arranged.
- a changeover valve in particular a 3/2-way valve, can be arranged in this connecting line. If the reservoir is to be switched on, this changeover valve is brought into the through position so that the pressure medium located on the rod side of the pressure medium motor or on the piston side of the auxiliary pressure medium motor can be diverted via the connecting line to the piston side by the piston movement.
- a check valve can be provided in the connecting line, which blocks the connecting line in the direction from the piston side to the rod side and is permeable in the reverse direction when a correspondingly high pressure is applied.
- the rod side is connected to the pressure medium tank via a 2/2-way valve with check functions. Depending on the position of the changeover valve, the pressure medium on the rod side is either directed into the pressure medium tank or onto the piston side of the pressure medium cylinder when the piston of the pressure medium cylinder is actuated.
- the reservoir can also be an additional pump.
- the device for carrying out the second method alternative according to the features b1, b2 provides that at least two pressure medium motors. These are tilting medium motors or pressure medium motors, which are provided for lifting as well as for tipping, are arranged in parallel and can be interconnected for emptying large waste containers.
- actuating sides of the pressure medium motors are connected to one another via a connecting line, in which a changeover valve, in particular a 2/2-way valve with a check function, is preferably also arranged.
- a changeover valve in particular a 2/2-way valve with a check function

- the volume flow Q G is too low for emptying small waste containers, and a drain Pmax of this magnitude is not necessary.
- a volume flow Q K1 or Q ⁇ is required, for example.
- With the same power, which is predetermined by Lmax this results in corresponding pressures P K1 and P, ⁇ .
- the services required for emptying small waste containers are shown by the dash-dotted lines for the two cases mentioned.
- the corner points of the associated rectangles move on an envelope 1. From this it can be seen that the higher the desired volume flow, the lower the available drain. How the pressure Pmax can be converted into a higher volume flow Q is explained in connection with FIGS. 4 to 8.
- FIG. 3 shows the performance diagram for the second procedural alternative, which is based on the maximum volume flow Qmax for emptying small waste containers.
- the associated drain P ⁇ is accordingly lower.
- the pump output Lmax is also identified by the hatched rectangle.
- This high volume flow with the associated lower drain P ⁇ must be converted into a large pressure P G 1 or P G2 with a correspondingly lower volume flow Q G1 or Q G: for emptying large waste containers become. This in turn depends on the size or weight of large waste containers to be emptied.
- FIG. 4 shows a hydraulic circuit diagram for two lifting and tilting devices arranged next to one another.
- the draining system shown has two draining circles A and B, which are assigned to the two lifting and tilting devices.
- the components of the drain medium circuits correspond, the reference numerals of the components of the pressure medium circuit A being identified by a and the components of the drain medium circuit B being identified by b.
- Each drain center circuit A, B has a lifting cylinder 14a, 14b and a tilting or swiveling cylinder 15a, 15b.
- a common pressure medium tank 1 is provided for both drain medium circuits A and B and is connected to a drain medium pump 3 via a feed line 2.
- the outlet of the drainage medium pump 3 is connected to a flow divider 4 which has two flow divider branches 5a and 5b.
- a draining agent supply line 6a, 6b in each of which a control valve 7a, 7b is arranged. This is, for example, a three-way, three-position valve (3/3 valve).
- a return line 8a, b is also connected to the control valve 7a, b.
- the draining agent feed line 6a, 6b merges into a draining agent feed line 11a, 11b, which branches in a first feed branch 12a, b and a second feed branch 13a, b.
- the second feed branch 13 a, b is on the Drackstoffmotor 14a, 14b connected, which is responsible for the lifting process.
- the first feed branch 12a, b opens out on the piston side 16a, 16b of the drain medium motor 15a, 15b, which is responsible for the tilting process.
- Beneath the piston 18b is the rod side 17b of the drain motor 15b, which in the embodiment shown in the drain circle B forms the reservoir 100.

- the left middle drain circuit A on the left side of the illustration in FIG. 4 can be designed in exactly the same way as the middle pressure circuit B.
- a further embodiment is shown in the draining center circuit A, in which the rod of the piston 18a is connected to the rod 25a of an auxiliary pressure medium motor 26a.
- the piston side 28a of this auxiliary pressure medium motor 26a forms the reservoir 100 in this case.
- This auxiliary pressure medium motor 26a is dimensionally smaller than the pressure medium motor 15a, so that when the piston 18a is acted upon, the piston 27a is pressed downward.

The draining agent can then via the connecting line 22a.
- valves 7a, b have different tasks.
- the valve 7a In the position of the valve 7a shown, large containers are emptied at a lower speed because half the volume flow of the pump is returned to the tank 1 via the valve 7a.
- the valve 7a is brought into its second position, so that the entire volume flow of the pump 1 is available via the lines 6a, b and the speed of the tipping is almost doubled.
- the functions of the valves 30a, b and 31a, b are analogous to the description of FIG. 6 of the drawing. However, these valves can also be replaced by valves 24a, b.
- FIG. 8 Another embodiment is shown in FIG. 8, in which only one drainage cylinder 15a, 15b is provided for both lifting and tipping.
- the functioning of the other components of the drainage medium circuits A and B corresponds to that of the embodiments described above.
- a targeted control of the desired speed can be carried out by temporarily switching 24a or b on or off.
- FIG. 9 shows a circuit diagram for the implementation of the second alternative method.
