Definitions

  • the present invention is related to methods for weighing, in particular of household waste containers of small volume, used by residents to collect waste and collected on a regular basis by waste collection services.
  • a system for this purpose is for example described in document EP-A-186820.
  • a lifting mechanism is attached to the back of the collection truck.
  • a filled container is hooked onto this mechanism, lifted up and weighed a first time.
  • the emptying cycle continues until the container is emptied, and returns on a downward path. In the course of this path, the container is again weighed.
  • Electronic registering means are present to record the two weight values. These values allow to derive the weight of the waste actually emptied into the collection truck.
  • Even though systems of this kind are known, there is a basic flaw in the way in which the weight is determined. This is related to the fact that the actual weight value is obtained by subtracting one measured value from another.
  • the norm EN45501 (1992) does not allow a net weight to be obtained by subtraction, as this increases the measurement error.
  • the present invention aims to provide a method for weighing waste containers, which does not suffer from the drawbacks of the prior art methods.
  • Figs. 1 and 2 represent a waste collection truck with a lifting mechanism, used to implement the method of the invention.
  • the method of the invention is applicable to a lifting and weighing mechanism similar to the ones known in the art.
  • a mechanism comprises, on the back of a waste collection truck 2, a lifting and emptying device 3 to which a waste container 1 may be attached.
  • the container is attached in such a way that after it is lifted from the ground, its weight is measured by a weighing mechanism 6, integrated in the emptying device.
  • the weighing mechanism typically comprises one or more load cells (not shown), which produce an electrical signal related to the suspended weight.
  • the actual weighing is preceded by an identification step, involving an identification element 4, preferably an electronic chip, attached to the container 1, which is put in contact with a sensor means 5, able to read the information contained in the chip. In this way, an identification code can be read by the sensor means, and registered by saving it into a data collection means 7.
  • the method of the invention comprises the following steps :
  • the new and inventive step of this method resides in the taring.
  • the weighing mechanism is put to zero.
  • the weighing step during the lowering phase is performed relative to the zero, so that a negative weight is measured, the absolute value of which corresponds exactly to the net weight of the collected waste.
  • This value can than be stored in the data collection means 7, along with the identification obtained from the ID-element 4.
  • a 'weighing step' is defined as a procedure whereby a weight value is determined, followed by the registration of said value.
  • only one such weighing step is present, during the lowering phase.
  • the weighing mechanism is tared, which does not consitute a weighing step in the meaning set out above, as this does not involve recording and storing a weight value. This defines the difference between the method of the invention and the prior art.
  • the method can be performed as an automatic measurement cycle, which is launched when the container is attached to the emptying device 3, and ends when the container is released from this device.
  • the method can be performed in such a way that certain steps have to be done manually, for example the steps of taring and weighing.
  • detectors are present on the emptying device, which monitor the emptying path and allow to interrupt the emptying cycle in case of an error, for example when the taring or weighing steps have been compromised due to external influences.
  • detectors are present on the emptying device, which monitor the emptying path and allow to interrupt the emptying cycle in case of an error, for example when the taring or weighing steps have been compromised due to external influences.
  • the method may equally comprise a step wherein the user manually enters data, which are to be stored along with the registered net weight and the identification data. For example, a code may be entered which is related to the type of waste, a defect on the waste container or other information.
  • the method of the invention may also comprise a step of sending signals from the data collection means 7 through the sensor means 5 to the identification element 4, in case this element consists of a read/write chip.
