Abstract

A method and apparatus is provided for monitoring the processing of a group of articles having different properties, for example differing weights and/or quality grades. The method includes the steps of obtaining information about the differing properties of the group, using this information to provide a main visual model of the property distribution within the group, and providing a first subsidiary visual model relating to the processing of a first sub-group of articles from within the group, the provision of the first subsidiary model causing a modified form of the main visual model to appear, related to the remaining articles of the group after removal of the articles forming the first sub-group. The method is particularly effective for use in monitoring the processing of poultry carcasses being conveyed in succession along a path, for sorting by weight and grade of carcass. The method may be used in advance of processing, to run a test as to what might happen during processing according to different parameters, and it can also be used during actual processing, to monitor what is actually happening, against a target time, numbers and maximum processing capacities.

Claims

1. A method of monitoring the processing of a group of articles having different properties, the method comprising the steps of:

obtaining information about the differing properties of the group;

using this information to provide a main visual model of the property distribution within the group; and

providing a first subsidiary visual model relating to the processing of a first sub-group of articles from within the group which comprises a band width spanning a desired range of properties, the provision of the first subsidiary model causing a modified form of the main visual model to appear, related to the remaining articles of the group after removal of the articles forming the first sub-group.

2. A method as claimed in claim 1, in which the step of obtaining information about the differing properties of the group is achieved by using statistical data relating to the relevant group, or by random sampling of the actual group.

3. A method as claimed in claim 1, further comprising the step of providing at least a second subsidiary visual model relating to the process of a second sub-group of articles from within the group, the provision of the second subsidiary model causing a second modified form of the main visual model to appear, related to the remaining articles of the group after removal of the articles from the first and second sub-groups.

4. A method as claimed in claim 3, in which the first sub-group of articles relates to the highest demand priority.

5. A method as claimed in claim 1, in which the main visual model comprises a graph.

6. A method as claimed in claim 1, in which said modified form of the visual model is numerical.

7. A method as claimed in claim 1, such that the main visual model remains in view, in addition to a modified form of the visual model.

8. A method as claimed in claim 1, in which the properties are represented as weight bands, a preselected band width comprising a visual indicator extending across an optimum desired weight band.

9. A method as claimed in claim 8, in which the indicator is displayed as a horizontal bar.

10. A method as claimed in claim 9, in which the indicator is extendable at one or both ends, when it is permissible to fill a given demand with articles which vary slightly from the optimum, when insufficient articles having the optimum property are available.

11. A method as claimed in claim 9, in which when, in a practical situation, a given form of processing within the group has to be changed or stopped, the method includes highlighting the relevant visual indicator to warn the user what is happening.

12. A method as claimed in claim 9, in which the indicator comprises a horizontal bar, and the nature of the bar changes when processing is altered or stopped.

13. A method as claimed in claim 12, in which a solid bar is used for normal conditions, the bar becoming hollow when processing changes or stops.

14. A method as claimed in claim 1, further including the step of providing a visual model of the consequent effect of changing or stopping an aspect of the processing.

15. A method as claimed in claim 14, the step of creating a visual model showing articles rapidly bunching up and/or jamming.

16. A method as claimed in claim 1, such that a visual model is provided of what is happening at certain particular processing points.

17. A method as claimed in claim 1, further comprising obtaining information about sub-groups of articles being received for processing, comparing this information with processing steps to be carried out, and using this comparison to select the order in which sub-groups are processed.

18. An apparatus for monitoring the processing of a group of articles having differing properties, said apparatus comprising:

means for obtaining information about differing properties of the group;

means for using this information to provide a main visual model of the property distribution within the group; and

means for providing a first subsidiary visual model relating to the processing of a first sub-group of articles from within the group which comprises a band width spanning a desired range of properties, a provision of the first subsidiary model causing a modified form of the main visual model to appear, related to the remaining articles of the group after removal of the articles forming the first sub-group.

19. The apparatus as claimed in claim 18, comprising an appropriately programmed computer and a visual display unit on which the visual models appear.

20. The apparatus as claimed in claim 19, in which the computer and visual display unit are a stand alone system.

21. The apparatus as claimed in claim 19, in which the computer and visual display unit are part of an overall computer system which controls and operates processing equipment.
