Definitions

  • the invention relates to a device for emptying containers, in particular garbage containers in collecting containers, in which a lifting and tipping device or tilting device driven by at least one pressure medium motor is provided with a lifting and tipping frame or tilting frame which receives the container to be emptied, the pressure medium motor or the pressure medium motors using a in the pressure medium power circuit used pressure medium valve is controlled, which is connected with its actuating device directly or indirectly to a control circuit which contains a time switch determining the time valve control for the movement sequence.
  • a device of this type is known from DE-A 27 21 059, in which a pressure switch which is attached to the side of the bed and is to be operated by hand is provided as the element which initiates the emptying process.
  • a pressure switch which is attached to the side of the bed and is to be operated by hand is provided as the element which initiates the emptying process.
  • a garbage can tipper in which the control valve for the pressure medium motor is provided with a manual actuation element which, when the valve is brought into the actuation position for the pressure medium motor, can be inserted behind a retaining bar, one of which is also in the pressure medium power circuit arranged release device is assigned such that it pushes the manual control element of the control valve behind the retaining bar and releases the control valve to return to the starting position as soon as the corresponding compressed air supply is reached on the release device.
  • the disengaging device itself is controlled by an overflow valve which is actuated by the pivot shaft of the tilting device or lifting and tilting device.
  • a corresponding actuation cam can be provided on the pivot shaft of the tilting device or lifting / tilting device for the overflow valve and a flow restrictor in the feed line of the disengaging device. This causes a multiple in and out tilting movement in the end tilting area of the tilting device or lifting and tilting device until the disengaging device is pressurized sufficiently to release the manual control element from the retaining bar, so that the control valve can return to its initial position.
  • this known device requires pneumatic pressure medium power circuits and, above all, makes it necessary for the emptying process to be initiated by manual actuation on the control valve and for the manual actuating element of the control valve to be locked.
  • Both known devices also make it necessary, when operated by a single person, that either the container to be emptied is attached to corresponding devices of the lifting / tilting frame or the tipping frame, or the operator simultaneously fixes the container to be emptied holds and controls the control valve, which often leads to incorrect reception of the container on the lifting and tipping frame and / or incorrect operation of the control valve.
  • two persons would normally be necessary in the known devices mentioned above.
  • the invention has for its object to substantially improve a device of the type described in such a way that a largely automatic control of the emptying process is made possible, which allows the container to be emptied by an operator only to the lifting and tipping frame and the operator can leave the device during the pouring process, for example in order to remove an emptied container and to fetch another container to be emptied.
  • the improved device should be able to be operated with pressure medium systems of any kind, be it with hydraulic or pneumatic pressure medium, with a simple structure, simple operation, high operational reliability and particularly economical operation of the device.
  • the invention is intended to ensure that during the automatic emptying process no danger is caused by this device for the operating personnel or uninvolved persons.
  • control circuit of the pressure medium valve contains a switching element actuated by the container attached to the lifting / tilting frame or tilting frame of the emptying device in order to initiate the control process.
  • the inventive arrangement of the switching element initiating the control sequence for direct actuation the container only has the function of safely and correctly bringing the container to the emptying device in order to simultaneously ensure the correct attachment of the container to the emptying device and to initiate the control sequence for the emptying process . In this way, even with one-man operation, a significantly increased level of safety can be achieved with the emptying process running automatically.
  • the switching element actuated by the container can be a touch switch which interacts with wedges of the container.
  • touch switches have the advantage that they are only mechanically actuated by the container placed in the correct position.
  • the switching element actuated by the container can also be formed by one or more sensors interacting without contact with parts of the container.
  • sensors of various types come into consideration, for example ultrasonic sensors, which respond to the reflection of ultrasonic waves hitting the container wall.
  • Magnetic switches are also suitable which respond to the approach of magnetic parts attached to the container wall.
  • any optically or electrically working sensors can be considered.
  • Another possibility according to the invention is to form the switching element actuated by the container by means of one or more light barriers interacting with the container.
  • the signal generated by the switching element actuated by the container will have to be transmitted via cable connection to the corresponding parts of the control circuit.
  • the switching element actuated by the container to be emptied is generally permanently installed and is often attached to the tipping frame or lifting and tipping frame and, on the other hand, containers with very different designs, some with considerable differences in the design of their lateral boundary walls, are still in traffic at the same time, it is recommended that in the context of the invention to provide a manual control switch in parallel to the switching element actuated by the container to be emptied or in parallel to the receiver used in the control circuit.
  • This additional hand switch has the purpose that the operator can initiate the emptying process by means of the manual control switch if such a container has been brought to the emptying device that is not suitable for the automatic triggering of the switching element.
  • the manual control switch can be used to switch on the control sequence on the Actuating device of the control valve can be attached and a common manual operating element for the manual operating switch and the control valve can be provided.
  • the electrical control circuit provided for the temporal valve control is designed, when the attached container actuated switch to control the tilting device or lift-tilting device to return to the starting position, preferably immediately when this switch is released or the circuit closed with the switch is interrupted. This ensures that if the container to be emptied is detected incorrectly or unsafe by the tilting device or lifting / tilting device, the initiated emptying process is immediately interrupted and reversed so that the container to be emptied can be added.
  • the electrical control circuit controls a secondary control circuit operated by means of a pressure medium, in such a way that a changeover valve which is set up for electrical and possibly also manual actuation and is connected to a pressure medium source via the time switch designed as a timing relay Control circuit is switched.
  • the pressure medium valve provided for the control of the pressure medium motor or the pressure medium motors is set up for pressure medium actuation.
  • the arrangement of an additional pressure medium control circuit can be advantageous under certain circumstances if that is not sufficient for an electrical actuating device of the control valve in the power pressure medium circuit or if a sufficiently safe electrical control current source is not available.
  • a buffer is arranged between electrical switching elements and the pressure medium power circuit or the valves arranged in the pressure medium power circuit.
  • a target can increase the force required to actuate the valve arranged in the power / pressure medium circuit and increase the control energy.
  • the control valve in the pressure medium power circuit can be a two-position valve with neutral and working position. This is particularly favorable in view of this, because the actuating device of such a two-position valve can be designed particularly simply. In a hydraulic pressure medium power circuit, it is advisable to switch such a two-position valve in the neutral position to a bypass line connected to the return line of the pressure medium power circuit.
  • a hydraulic drive of the tilting device can be used to rhythmically interrupt or restrict the pressure medium supply, operated by the control circuit, in the flow of the pressure medium power circuit to the drive element for the tilting device.
  • the invention is for both single and multiple fillings, for example double or twin fillings, triple fillings and the like. applicable, that is to say in the case of fillings in which two or more separately actuatable individual lifting and tipping devices or individual tipping devices are arranged next to one another.
  • the invention can be applied to so-called combination beds, namely those beds in which two or more individual lifting and tipping devices or individual tipping devices are arranged next to one another and can be operated separately or together, so that the individual lifting and tipping devices or individual tipping devices separately and independently of each other for emptying smaller containers and the entirety of the lifting and tipping devices or tilting devices can be used together for emptying larger containers.
  • the automatic sequence of the emptying process takes place both in separate operation on all individual lifting and tipping devices or individual tipping devices and an automatic sequence of the emptying process of a modified type also in combination operation of the totality of the lifting and tipping devices or Tipping devices are carried out.
  • the invention offers the possibility of providing the automatic sequence of the emptying process only for operation as individual lifting and tipping devices or individual tipping devices and for providing improved manual control operation for operation as a combination bed. This offers the advantage that the operator largely controls the emptying process himself in the case of a combination filling and can adapt it to the circumstances of the individual case, which are much more prominent in the case of larger containers.
  • an embodiment is therefore proposed in which two identical pressure medium power circuits are provided for the pressure medium motors of each lifting and tilting device or tilting device, which can be connected in parallel by means of a switching valve designed as a shut-off and switching valve and set up for electrical and possibly manual actuation are separable from each other, which is connected together with the control circuits provided for each individual lifting and tilting device or individual tilting device via a common switch to a power source and is in the shut-off position when the switch is closed.
  • the measure provided in this embodiment for two separate control circuits for both lifting and tilting devices or tilting devices ensures that when the power source is switched on, with both lifting and tilting devices or tilting device automated emptying processes can be carried out independently of one another.
  • the automatic control system is switched off.
  • the changeover valve arranged between the two pressure medium power circuits is in such a switching position that the pressure medium motors of both lifting and tilting devices or tilting devices are fed by a common pressure medium source.
  • Switching off the automatic control when operating both lifting and tipping devices together takes into account the fact that the length of time for the emptying process can be quite different for larger containers. In the case of a fixed time constant of the time switch determining the temporal valve control for the movement sequence, the economy of the simple embodiment of the invention was therefore not always given. Other conditions arise - as explained below - if the filling weight of the containers is determined by additional devices before emptying and this additional information is taken into account in the automatic control of the emptying process.
  • the control valves for the pressure medium motors are designed as two-position valves, and vice versa as the first Changeover valve controlled and inserted in a power circuit before connecting the pressure medium connection line in the pressure medium supply line of the pressure medium motors. It is hereby achieved in an advantageous manner that the device for the common is achieved solely by depending on the power source from the two control circuits and the electrically actuable control valves, for example by means of a main switch Actuation of both lifting and tipping devices or tipping devices for emptying large containers is ready for operation.
  • movable barrier elements can be provided on the side walls of the collecting container in a securing position that laterally shuts off the working area of the lifting / tilting device or tilting device.
  • these barrier elements are to be connected directly or indirectly to a shut-off valve located in the pressure medium supply line of the pressure medium power circuit or the pressure medium power circuits, such that the pressure medium supply to the power circuit or the power circuits is only opened in the securing position of the barrier elements. It is thereby achieved that the automatic emptying of containers, but also, if possible, the manual emptying of containers is only possible when the barrier elements are closed.
  • the electrical control for automatic operation is switched off, the locking of the power / pressure medium circuits when the barrier is open can be dispensed with, since with manual control an operator is always on anyway Filling must be present and can then also take over the task of securing the work area.
  • no measures are taken to either secure the work area by means of the barrier elements or to dispense with the device Protection can be switched using barrier elements.
  • the barrier elements are connected to a main switch which is inserted in front of the electrical control circuit or control circuits and is only inserted in the locked position of the barrier elements.

  • This entered or automatically recorded identification information is compared in the programming and switching device with the stored data about the containers that are to be emptied.
  • the programming and switching device contains circuit arrangements which, from this comparison, determine a proposal for a control mode of the device which appears to be most suitable for emptying the container which has been brought up.

  • the erfindugnshunte device can be off in this Guide e g sForm for discharging a plurality of different types of containers used, provided that the necessary mechanical devices are provided on the bed or the random packings.
  • this fully automatic embodiment of the invention can consist in the fact that the electrical control circuit and the valve control interconnected additional elements for setting the initial position of the lifting / tilting frame or tilting frame suitable for the container to be emptied, if necessary with a connection to the instantaneous filling weight of the Containers detecting device included.
  • this additional facility means that after Determining the height or the type of the container to be emptied, the lifting and tipping frame b or the tipping frame is first preset to a suitable height.
  • the instantaneous filling weight of the collecting container for example the garbage truck, can also be used, since the collecting container is lowered deeper into the suspension as the filling weight increases, in particular on garbage vehicles.
  • a particularly favorable embodiment of this additional device can be achieved by reading off the reading of a suitable height presetting of the tilting frame or lifting / tilting frame with the above-mentioned photoelectric reading device of a detection mark on the container.
