Abstract

A remedy judging system includes a weight checking device and a judgment unit. The weight checking device checks the weight of weighed product discharged from a weighing device. The judgment unit makes a judgment relating to remedies for the weighing device on the basis of “correct weight,” “overweight,” and “underweight” checking results, relative to a predetermined weight serving as a norm, obtained by the weight checking device. The judgment unit makes the judgment on the basis of determination patterns having an “underweight” checking result and at least one checking result that consecutively follows the “underweight” checking result.

First claim

What is claimed is:

1. A remedy judging system comprising:
a weight checking device that checks the weight of weighed product discharged from a weighing device; and
a processor that makes a judgment that comprises identification of at least one area for remedy in the weighing device on a basis of a correct weight checking result, an overweight checking result, and an underweight checking result, relative to a predetermined weight serving as a norm, obtained by the weight checking device,
wherein the processor makes the judgment based on determination patterns having the underweight checking result and at least one checking result that consecutively follows the underweight checking result, the determination patterns including:
a first determination pattern that the underweight checking result is consecutively followed by the overweight checking result,
a second determination pattern that the underweight checking result is consecutively followed by all correct weight checking results a first predetermined number of times, and
a third determination pattern that the underweight checking result is consecutively followed by the correct weight checking result and the overweight checking result within a second predetermined number of times after the correct weight checking result.

2. The remedy judging system of claim 1 , wherein the processor reports the judgment.

3. The remedy judging system of claim 1 , further comprising a packaging device that packages the weighed product, wherein the processor makes the judgment relating to remedies relating to the weighing device and the packaging device.

4. The remedy judging system of claim 1 , wherein
the weighing device includes a hopper that retains product that is to be weighed, and
the processor makes the judgment relating to remedies for the hopper.

5. The remedy judging system of claim 4 , wherein the hopper has a timing hopper that discharges the weighed product.

6. The remedy judging system of claim 5 , wherein
the weighing device further includes a chute that delivers the weighed product to the timing hopper,

the remedy judging system further comprises a packaging device that packages the weighed product, and
the processor, in a case where the underweight checking result is consecutively followed by the overweight checking result, judges that a residual product in the timing hopper, a delay in the discharge of the product at the chute, or clogging of the packaging device with the weighed product is to be remedied.

7. The remedy judging system of claim 4 , wherein
the hopper has a weigh hopper that weighs the product, and
the processor, in a case where the underweight checking result is consecutively followed by all correct weight checking results the first predetermined number of times, judges that a residual product in the weigh hopper is to be remedied.

8. The remedy judging system of claim 4 , wherein
the hopper has a booster hopper that holds the product, and
the processor, in a case where the underweight checking result is consecutively followed by the correct weight checking result and there is the overweight checking result within the second predetermined number of times after the correct weight checking result, judges that a residual product in the booster hopper is to be remedied.

9. The remedy judging system of claim 1 , wherein the processor communicates with the weighing device and the weight checking device.

10. The remedy judging system of claim 1 , wherein the weight checking device learns the determination patterns by machine learning and accumulates determination results based on the determination patterns.

11. The remedy judging system of claim 1 , wherein, in response to an occurrence of the underweight checking result, the processor makes the judgment based on the determination patterns having the underweight checking result and at least one checking result that consecutively follows the underweight checking result.
