## Abstract

A conveyance system includes a feeding device, a reading device, a weight measuring device, a storage device, a notification device, and an arithmetic control device which compares the number of pickings of the articles obtained by dividing a difference between the reference weight value and a measurement value after operation as a weight of the container after picking of the articles by the unit weight, with the number of incoming orders, determines whether there is an excess or deficiency, and when there is an excess or deficiency, notifies the excessive or deficient number of articles by the notification device.

## Claims

### Claim 1

A conveyance system comprising:
a feeding means that enables feeding of containers that store articles to which article-related information is associated;
a reading means capable of reading the article-related information of the articles assigned to the container;
a weight measuring means that measures a weight of the container storing the articles;
a storage means that stores the article-related information of the articles;
a notification means that notifies an excessive or deficient number of the articles; and
an arithmetic control means that performs counting management and sorting control of the articles, wherein
the article-related information includes a unit weight of the articles, the number of incoming orders of the articles, and a reference weight value derived by measuring or calculating a weight of the container storing the articles,
the arithmetic control means compares
a number of pickings of the articles obtained by dividing a difference between the reference weight value and a measurement value after operation as a weight of the container after picking of the articles by the unit weight, and
the number of incoming orders,
determines whether there is an excess or deficiency, and when there is an excess or deficiency, notifies the excessive or deficient number of articles by the notification means.

### Claim 2 (depends on 1)

The conveyance system according to claim 1, wherein in the container, articles of the same kind are stored.

### Claim 3 (depends on 2)

The conveyance system according to claim 2, wherein
to a region in which the articles are picked in the feeding means, a roller conveyor is applied, and
below the roller conveyor, a lifting and lowering means that lifts and lowers the weight measuring means is disposed,
a support portion capable of advancing and retreating at a portion between rollers of the roller conveyor, and capable of supporting the container, is provided to extend at an upper surface side of the weight measuring means, and
the arithmetic control means
lifts the weight measuring means by the lifting and lowering means before picking of the articles from the container, and the weight measuring means measures weights of the container before and after picking of the articles at an upper side of the roller conveyor.
