Definitions

  • the present invention relates to a device for the mobile weighing of an article fixed to a movable carrier, which carrier is fixed to a frame, and in which at least one load cell, connected to an external processing unit, is present between the carrier and the frame.
  • Such a device is known from German Offenlegungsschrift 3.89.169.
  • a load cell is fitted between the frame and the carrier, for the purpose of weighing a refuse bin.
  • the frame is fitted on the back of a refuse lorry.
  • the analog signal coming from the measuring or load cell is fed to a processing unit, for further processing.
  • the object of the present invention is to avoid this disadvantage. This object is achieved in the case of a device of the type described above in that means are present in the load cell for digitising the signal to be fed to the processing unit, and that the load cell comprises means for compensating for the moment applied by the article to the carrier. This means that the centre of gravity of the article to be weighed is no longer important.
  • a load cell with means for digitising is known per se from US Patent Specification 4,657,097-
  • the digitising ensures that the risk of faults occurring in the line between the load cell and the processing unit is completely removed.
  • the simpler processing of the output signal is also disclosed therein.
  • the device according to US Patent Specification 4,657.097 is not suitable for compensating for variation of the centre of gravity of the article to be weighed, as a result of which variation a changing moment is exerted on the carrier.
  • the means for compensating for this changing moment can comprise, for example, compensating strain gauges already present in such weighing devices, or possibly other added strain gauges which measure in directions other than the usual ones.
  • a hinge construction is fitted between the load cell and the frame.
  • the fact that the signal from the load cell is delivered in digital form means that it is possible to use various load cells in parallel, and to couple the signals coming from them by means of at least one bus coupling and feed them together to a processing unit. This makes it possible, for example in the case of a refuse lorry, to empty two bins at once, and to measure their weight simultaneously, while only one processing unit is necessary, and there is no risk of mutual interference between signals.
  • Fig. 1 shows diagrammatically the back of a refuse lorry with a refuse bin
  • Fig. 2 shows the diagram of the load cell with the processing device used in Fig. 1; and Fig. 3 shows a further embodiment of the device according to the invention.
  • Fig. 1 the back of a refuse lorry is shown diagrammatically and is indicated by 1.
  • Fixed to it is a parallelogram construction 2, on the end of which a frame 3 is fixed.
  • Frame 3 can be moved up and down, in a manner not shown in any further detail, by means of jack devices acting upon the parallelogram construction 2.
  • Frame _ is provided with a pivot point 4, in which one end of a load cell 5 is fastened so that it rotates freely.
  • the other end of load cell 5 is rigidly connected to carrier 6.
  • carrier 6 is provided with means for gripping a bin 8.
  • the signal coming from load cell 5 is transmitted by means of a line 9 and a coupling device 10 to a bus line 11, which is in turn connected to a processing unit 12.
  • the cell used here is a so-called digital cell, i.e. the analog signal coming from the strain gauges in the cell is already converted to a digital signal in the cell.
  • Means are also present in the cell for compensating for displacement of the centre of gravity of the bin.
  • the centre of gravity of bin 8 lies at point 13, due to the fact that a relatively heavy piece of material is present near the bottom end. It will be understood that if the centre of gravity 13 is moved further to the right in Fig. 1, this has an effect on the moment acting on the load cell. Compensation for the moment can be provided by, according to the invention, fitting in the load cell compensating devices, which can comprise compensating gauges already present in such load cells, or in particular compensating gauges fitted in other directions.
  • Fig. 3 shows a further embodiment of the invention.
  • the frame 15 is fixed immovably to the environment, and the carrier 16 is composed of two parts.
  • One part 17 of the carrier 16 is fixed immovably to part 15 by means of load cell 18, while the other part, indicated by 18, can be moved on the part 17 of the carrier.
  • load cell 18 can be used for, for example, all kinds of handling devices where moving articles have to be weighed. If, for example, its application is intended in slaughterhouses, a suspension hook 19 for carcasses can be fitted on part 18.
  • a suspension hook 19 for carcasses can be fitted on part 18.
