DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method for measuring diamensions of a three-dimensional object, wherein said object is placed in a measuring corner which defines an x, y, z three-dimensional coordinate system, and wherein in connection with each coordinate at least one graded scale means is provided. Further, the invention relates to a system for measuring dimensions in this way, wherein the corner is formed by two vertical walls, optionally one vertical wall and a graded scale means, which are positioned at mutual angle of 90.degree., and a horizontal base on which the object is placed when being measured.
Volume measuring devices of this kind are previously known, and U.S. Pat. No. 2,736,095, in particular, teaches one such device where two vertical walls arranged so as to be mutually 90.degree. apart forming a corner together with a conveyor upon which an object is placed. Scale means are disposed in the form of a plurality of graded markings on the two walls so that, for example, the length of the object can be measured along said graded markings by means of a set square whilst said object lies adjacent to one of said walls where curves indicate a defined surface area. Alternative solutions are also found in U.S. Pat. No. 4,268,967. One disadvantage with the known systems is that to take the desired measurements along the coordinates is time-consuming, whereafter the volume must be calculated either by using tables or a separate calculator into which the measured coordinates are entered. For the rational handling of objects such as packages which are to be sent, for example, by mail or another form of transport, it is essential to take readings of and calculate the desired data for the package as quickly as possible.
According to the invention, this is done by using partly known means, per se, and the method is characterized in that the incremental markings on the scale respective means are provided with an optically machine-legible code, for example, a bar code, which represents a respective distance from the origin of the coordinate system, that the code for each coordinate is read by an optical/electrical reader by said reader being moved towards or caused to detect a coded marking at the respective coordinate lying freely nearest to the object, wherein said marking contains both information regarding metric dimension and also the perspective coordinate axis, that the code is registered by the reader, that the code registered by the reader is converted to an electrical signal which is signal-processed on the basis of the received signal for each coordinate, and to calculate and provide a print-out or display of characteristic data of the object, for example, measured x, y and z coordinates, length, width and height, the calculated cubical volume, greatest length plus circumference, etc.
A combined optically machine-legible code can, to advantage, be provided for the respective measuring points in at least one of the planes xy, xz or yz of the coordinate system. Thus, in effect, only two readings are needed to calculate said exemplary disclosed characteristic data of the object. When the method is used for calculating the freight charge, it is expedient to have a computer calculate said freight charge on the basis of said calculated, characteristic data, possibly also the weight of the object.
The system according to the invention is characterized in that the graded scale means has an optically machine-legible code on its respective graduated markings, for example, bar code, that an opto/electrically functioning code reading device is provided, for instance, a manually operated bar code reader, for reading the code which is closest to the respective coordinate, wherein said marking code contains both information regarding metric dimension as well as respective coordinate axis, and that the code reading device is connected to a signal processor for calculating and displaying, for example, by means of an optical display or printer, the characteristic data of the object, for example, x, y, and z coor
