Abstract

The invention provides dimensional weighing apparatus (5) that may e.g. be placed transparently between the weighing scales (3) and POS terminal (4) of e.g. a postal outlet so as to provide dimensional weighing of a parcel (2). The apparatus (5) senses the parcel height with a sensor (10), and senses the parcel cross-section with a sensor (11) that obtains data points as the parcel (2) rotates on a turntable (12). A control unit (6) determines the parcel volume from the height and cross-section data, and determines a dimensional weight based on the volume and on a minimum chargeable weight per unit volume. It compares the dimensional weight with the actual weight from the scales (3), and outputs the larger value to the POS terminal (4). Various sensor arrangements and profile analyses are described.

Claims

1. Dimensional weighing apparatus for use with object weighing apparatus and object pricing apparatus, the dimensional weighing apparatus including:

sensing apparatus for determining size data for an object to be weighed; and

control apparatus which receives size data from the sensing apparatus and which includes an interface for communicating with the weighing apparatus and an interface for communicating with the pricing apparatus;

the control apparatus in use being connected between the weighing and pricing apparatus, and outputting weight information to the pricing apparatus dependent on weight data from the weighing apparatus and size data from the sensing apparatus.

2. The apparatus of claim 1, wherein the control apparatus determines a dimensional weight for the object based on the size data, and outputs the larger of the dimensional weight and an actual weight of the object as determined from the weight data.

4. The apparatus of claim 1, wherein the sensing apparatus is adapted to determine the size of the object whilst the object is on the weighing apparatus.

6. The apparatus of claim 1, wherein the sensing apparatus includes non-contact type sensors.

7. The apparatus of claim 1, wherein the sensing apparatus includes sensors that sense a distance to the object.

9. The apparatus of claim 1, wherein the sensing apparatus includes one or more vertically-oriented sensors arranged in use over the object and/or one or more horizontally-oriented sensors.

11. The apparatus of claim 1, wherein the sensing apparatus and object rotate in use relative to one another.

12. The apparatus of claim 1, including a turntable on which the object is placed for size determination the turntable being adapted to be mounted in use on the weighing apapratus.

14. The apparatus of claim 12, wherein the turntable is connected to the control apparatus, and is activated by a signal from the control apparatus.

18. The apparatus of claim 12, wherein the control apparatus correlates the size data with the rotational position of the turntable in order to determine a cross-sectional profile for the object.

19. The apparatus of claim 1, wherein the sensing apparatus provides data on at least one cross-sectional profile of the object and at least one height measurement of the object.

20. The apparatus of claim 1, wherein the sensing apparatus determines size data for a 360-degree profile of the object.

21. The apparatus of claim 19, wherein the control apparatus identifies the shape of the object through the peaks and/or troughs in the cross-sectional profile.

22. The apparatus of claim 21, wherein the control apparatus determines dimensions of the object cross-section based on the identified shape of the object, and on the dimension data for the object determined at the peaks and/or troughs of the profile.

23. The apparatus of claim 1, wherein the control apparatus determines cross-sectional profile data for the object and fits a minimum-area polygon to the profile data.

28. The apparatus of claim 1, wherein the sensing apparatus includes one or more reflector elements for directing a sensing beam from a sensor onto an object to be measured.
