Definitions

  • the present invention relates to a loading system for a refuse collection truck.
  • a loading system is used particularly to empty containers, for instance filled with waste, into a refuse collection truck.
  • the content of refuse containers is usually collected at company or private premises using refuse collection trucks. Such containers are here lifted using a loading system and emptied with a pivoting movement into the interior of a refuse truck.
  • the loading system is usually provided on the rear side of the refuse truck.
  • Known refuse trucks are also provided with a press or pressing system with which the content of the containers can be compressed in order to reduce the volume thereof.
  • a refuse truck drives up, empties the containers and drives away again. Depending on the number of containers, this will take some time.
  • For lifting of the container use is made of the power of the combustion engine. This engine drives a pump with which a hydraulic fluid such as oil is sent to the cylinders to cause pivoting of the lifting arm of the loading system. The disposal of waste and other materials in this way takes a relatively large amount of energy.
  • the present invention has for its object to provide a loading system for a refuse collection truck with which containers, for instance with refuse, can be emptied in a more efficient manner.
  • the energy needed to empty a container using a loading system for a refuse collection truck is required particularly during the lifting of a container during the pivoting movement of the lifting arms.
  • the lifting arms are connected for this purpose to a drive to make this movement possible.
  • the drive is controlled here.
  • the operating means of this control are preferably placed at or close to the loading system so that the user of the loading system can activate the drive whereby emptying of a container is initiated.
  • Providing variably adjustable activating means achieves that the drive is wholly or partially activated. That is, the drive is controlled such that the energy provided by the drive substantially corresponds to the energy needed to empty a container. It is not by definition essential here for the drive to provide full power. It is possible in this way to have the energy provided correspond to the energy required without energy for instance being lost and being converted into for instance heat. This results in an efficient loading system.
  • An additional advantage of having the energy provided correspond to the energy required is that the development of heat in the system is counteracted. Wear of components hereby remains limited and it is optionally even possible to suffice with less maintenance. This means that the availability for use of the loading system is increased, whereby the efficiency of the whole system increases.
  • the number of lifting arms used to empty a container usually amounts to two, although operation can also be performed with one or another number of lifting arms.
  • the drive for lifting the arms can for instance comprise according to the invention a combustion engine and/or a battery or hydraulic accumulator.
  • the loading system provides for simultaneous emptying of multiple containers. This means that sometimes one, and sometimes also two containers are emptied simultaneously. If in an embodiment of the loading system according to the invention two containers can for instance be emptied simultaneously, it is possible to suffice with half-capacity of the drive when only one container is being emptied.
  • the content of the containers for emptying may also differ significantly in mass. An energy-efficient emptying can in this case also be realized according to the invention.
  • the drive further comprises a variably controllable hydraulic pump and a first energy source for controlling the pump.
  • the energy required to cause movement of the lifting arms for the purpose of lifting and setting down a container can be realized using a hydraulic pump which sends a hydraulic fluid, such as oil, to the cylinders which can realize the required movement.
  • a hydraulic pump which sends a hydraulic fluid, such as oil, to the cylinders which can realize the required movement.
  • the use of a variably controllable hydraulic pump achieves that the power produced by the pump can be made to correspond to the power required to empty a container.
  • the pump is controlled by a first energy source.
  • This energy source is for instance the combustion engine of a vehicle provided with the loading system according to the invention.
  • the drive further comprises a second energy source.
  • a loading system is usually applied in a vehicle.
  • this vehicle is a refuse collection truck, it is usually provided with a press or pressing system with which the content of the containers can be compressed.
  • the pressing system can herein make use of a hydraulic pump. It will be apparent that the power required for the pressing is considerably greater than the power required to lift the containers.
  • pressing is necessary once about four (mini-) containers have been emptied. This means that, in the case for instance 1500 containers per day are emptied, pressing is necessary about 375 times.
  • a commonly occurring situation in practice is that, when refuse is collected in a residential area, the refuse truck drives up, empties a limited number of containers and, after the period of time necessary for emptying, drives on again.
  • the refuse trucks continues here to make use of the combustion engine. In respect of power this combustion engine is usually necessary only for the pressing and, in respect of power, not for emptying containers. This means that the combustion engine continues to run, resulting in noxious odours, exhaust gases, noise and unnecessary fuel consumption.
  • An additional advantage is that, due to the fuel reduction, the operational range of a refuse truck provided with a loading system according to the invention is increased. By now providing a second energy source the loading system can be driven independently of the press and/or the combustion engine or the vehicle itself.
  • This second energy source preferably comprises at least one battery.
  • This second energy source comprises for instance a battery intended solely for the loading system. It is also possible to use the battery of a vehicle provided with the loading system according to the invention. It is further possible to use both batteries together for the loading system.
  • the second energy source is preferably connected operatively to a second variably controllable hydraulic pump.
  • This is particularly advantageous when a completely separate system is desired for the loading system.
  • it is possible according to the invention to use the second energy source to control the first variably controllable hydraulic pump this results in a relatively complex system in the case this first hydraulic pump is connected operatively to for instance the pressing system. This is for instance the case when this first hydraulic pump is situated on a drive shaft driven by for instance the combustion engine of the vehicle.
  • Providing the second energy source in combination with the second variably controllable hydraulic pump results in a separate system which can operate wholly independently of the combustion engine of the vehicle, and which can in addition operate wholly independently of the pressing system.
  • the second pump can here be adapted to the power required by the loading system.
  • the pressing system needs about 100 litres of oil per pressing action and the loading system about 40 litres of oil, or half this in the case only one mini-container is being lifted.
  • This use of separate pumps is for instance advantageous in the above outlined situation where containers are emptied in a residential area, resulting in the stated advantages.
  • An additional advantage of using a separate pump for the loading system is that the press pump need be switched on less often (for use for the purpose of the loading system). The lifespan of this pump is hereby increased.
  • the battery of the second energy source is preferably charged by at least one of the combustion engine, solar cell or mains electricity. It is hereby possible in the case of a combustion engine to prevent for instance excess energy being lost and to store this energy in a battery.
  • the battery is charged in environmentally-friendly manner using solar cells. Emission of substances and noise in for instance a residential area can be avoided in efficient manner using mains electricity.
  • the activating means comprise at least one control valve for electrical control of the first and/or second drive means.
  • control valve in the immediate vicinity of the drive means, for instance in the immediate vicinity of the hydraulic pump, control thereof is greatly simplified. It suffices to send an electrical signal from the control to the pump, where the control valve will activate the pump and the hydraulic pump will pump the hydraulic fluid to the cylinders for the pivoting movement of the loading system.
  • a direct control is hereby obtained without unnecessary use of long hydraulic hoses.
  • the invention further relates to a vehicle provided with a loading system as described above.
  • a vehicle provides the same effects and advantages as those stated for the loading system.
  • the drive is controllable separately of a drive for a press and/or the vehicle itself.
  • a match of components and powers can hereby be realized specific to the power required to empty the containers.
  • the invention likewise relates to a method for emptying a container, comprising the steps of:
  • a refuse collection truck 2 ( figure 1 ) provided with a loading system 4 is used to empty containers 6.
  • Refuse truck 2 is provided for this purpose with a large loading opening 8.
  • This loading opening 8 is bounded on the sides by side walls 10 of refuse truck 2.
  • loading system 4 is provided for this purpose with substantially the same width as refuse truck 2.
  • Loading system 4 comprises uprights 12 on which are mounted lifting arms 14 with which engaging mechanism 16 can be moved for the purpose of lifting a container 6.
  • engaging mechanism 16 makes a pivoting movement with lifting shaft 18, wherein container 6 is carried upside down into loading opening 8.
  • Refuse truck 2 is provided with two footboards 20 on which for instance a dustman can take up position during movement of refuse truck 2.
  • Refuse truck 2 is also provided with two rubber buffers 22 on which a container 6 rests during the pivoting movement. These cushions 22, with the plate on which they are mounted, are also embodied such that they can yield to some extent when they come into contact with obstacles on ground surface 24.
  • Loading system 4 is also provided with two guides 26 attached to the top part of loading system 4. The lid of a container can be pushed open with these guides 26 during the pivoting movement such that the content of container 6 disappears into loading opening 8.
  • a stop member 28 arranged on the top part of loading system 4 is a stop member 28, substantially along the whole width of loading opening 8. This stop member 28 prevents container 6 continuing to rotate during the pivoting movement. In the case of such a continued rotation container 6 would, without stop member 28, disappear completely into loading opening 8, and thereby into the interior of refuse truck 2.
  • Containers 6 are, among others, containers of the type EN 840-1, -2, -3 and -4 with respective volumes of 80-360 litres, 500-1200 litres, 770, 1100 and 1300 litres, and 750-1700 litres.
  • Engaging mechanism 16 ( figure 2 ) engages using a comb 30 under the edge of container 6.
  • the clamping plate or enclosing plate 32 closes, whereby the container edge is clamped and a container 6 cannot detach from comb 32.
  • lifting shaft 18 extends along the whole width of loading opening 8, and therefore over substantially the whole width of refuse truck 2.
  • Other embodiments, for instance with a divided lifting shaft 18, are also possible.
  • the pivoting movement of lifting arm 14 is realized using a first cylinder 40. Cylinder 40 is mounted at one outer end for rotation around shaft 36 and connected on the other extendable part to lifting arm 14 via shaft 38.
  • a second cylinder 34 which is mounted in the same manner on lifting arm 14 on this side of loading system 4.
  • lifting arm 14 will make a pivoting movement around rotation shaft 42, whereby it is possible to empty a container 6.
  • a possible embodiment of a refuse truck 2 provided with a loading system 4 according to the invention is provided with a pressing system or so-called packer 44 ( figure 3 ).
  • Press 44 is controlled hydraulically using pump 46.
  • Pump 46 is driven by the combustion engine of vehicle 2. This driving takes place using a power take-off or so-called mechanical PTO 48.
  • An oil reservoir 50 is provided for hydraulic fluids in the form of oil.
  • the drive shaft used to drive pump 46 is likewise connected operatively to variably controllable pump 52 which is used for loading system 4.
  • loading system 4 can likewise be controlled using electric pump 54, which is controlled using electric pump control 56.
  • the power required for pump 54 is supplied using a battery 58.
  • battery 58 is a separate battery for loading system 4.
  • battery 58 can also be the battery of vehicle 2.
  • the oil for the cylinders of the lifting mechanism of loading system 4 is filtered using filter 60.
  • a safety valve 62 is also provided in order to prevent hazardous overpressures.
  • Pumps 52 and/or 54 are operated from loading system 4 using a control signal 64. This control signal is generated with a control placed at loading system 4. Subject to the mode of use, one or both pumps 52, 54 are activated. After activation of one or more of pumps 46, 52, 54 oil is extracted by these pumps 46, 52, 54 from oil reservoir 50 via conduits 66, 68, 70. The respective pumps 46, 52, 54 then provide the press and the loading system with oil via oil conduits 72, 74, 76. The oil pressed out of the cylinder by the downward movements of the lifting arms of loading system 4 is fed back via return conduit 78 to oil reservoir 50. In similar manner the oil no longer required in pressing system 44 is fed back to oil reservoir 50 via return conduit 80.
  • a hydraulic diagram 82 ( figure 4 ) of a possible embodiment according to the invention comprises a combustion engine 84 which is used to control a controllable pump 86.
  • oil is supplied via non-return valve 90 and filter 92 to the hydraulic system 94 of loading system 4.
  • Oil from system 94 is fed back to the oil reservoir, for instance oil reservoir 50 of figure 3 .
  • a loading system 4 can be separately driven using a 24 V motor 96 which drives a pump 98.
  • Pump 98 transports oil from a reservoir via non-return valve 100, overpressure valve 102 and filter 92 to hydraulic system 94 of loading system 4. The oil no longer being used by system 94 is once again returned in the same manner to a reservoir.
  • a user When a container 6 is emptied, a user, such as for instance a dustman, makes a selection of the operating mode of loading system 4 to be used. This selection is made subject to, among other factors, the number of containers for emptying, possibly required pressing actions and the location where emptying is carried out (for instance a residential area).
  • a variable hydraulic pump or other type of drive which is provided with power by the combustion engine of the vehicle and/or the special battery for the loading system of vehicle 2.
  • the power supplied here can be made to correspond to the power required for loading system 4.
  • the combustion engine can for instance be switched on or 'revved' up in order to supply additional power for this pressing action. It is also possible to not use the combustion engine, and to make use of a second energy source, such as a battery, to drive this hydraulic pump. This has the above stated advantages in respect of, among other things, emissions.
  • a second variably adjustable pump such as a hydraulic pump, whereby an independent drive system for loading system 4 is obtained.
  • control, pump, valve and cylinders provided for the purpose of the loading system are separated from the pressing system.
  • the two provided pumps are also driven by the combustion engine or the electric motor.
  • the pump In a first mode the pump is coupled actively to the combustion engine when the combustion engine is switched on.
  • the control from the loading system is such that the correct amount of oil is supplied.
  • the engine speed is not controlled here by the loading system, so that this speed does not affect the operation of the loading system.
  • the electric motor with associated pump is switched on when the combustion engine is not active. If the combustion engine supplies insufficient oil, the electric motor is switched on.
  • the electric motor can be set as standard and the combustion engine is used only once the battery capacity has been used up. In this mode the combustion engine of the vehicle is switched off during the emptying of containers with the loading system.
  • the system is hereby made specifically suitable for the loading system in a manner such that an efficient and effective loading system is obtained.
