Description

  The present invention relates to a packing weight management system that performs a quantity inspection based on the weight of mechanical parts such as bearings and constant velocity joints, and other various articles, and a load weight management in a physical distribution process.

When a plurality of mechanical parts such as bearings and other various items are put in a packing container, shipped from the factory and received at the distribution center, the distribution center performs inspections by displaying slips and tags on the surface of the packing container. Do.
In general, the truck fare determined between the carrier and the client is generally determined based on volume when the weight is large, and is determined based on weight when the weight is heavy. When determining the fare on the basis of weight, when it is difficult to understand the weight, it is generally performed by presuming how many kilograms the weight is based on the size of the packaging container.

As an electronic management system, in a returnable box that transports agricultural and fishery products, an IC card is placed in a pocket provided in the returnable box for managing the transported goods, and product information and shipping information are stored in the IC card. It has been proposed to record various types of information and use them for physical distribution management (for example, Patent Document 1).
JP 2001-341845 A

At the time of inspection at the above delivery center, the packaging container cannot be opened, so the actual number of entries cannot be confirmed, and it relies on the display of slips and bills. Therefore, if there are not enough items in the packaging container, or if the labeling on the slips or the surface of the packaging container is incorrect, the display of the slips must be trusted and managed as it is. The reliability of management is still insufficient.
Also, in the case of an article that is heavier than its volume, such as mechanical parts, the weight of the packing container has been assumed in the past as described above. May exceed weight. On the other hand, the client side often has to pay a fare for a weight heavier than the actual weight, which is uneconomical.

  The method of performing various controls by putting an IC card in a pocket of a returnable box as shown in Patent Document 1 is suitable when the transported item is an agricultural product or a marine product, but in the case of a machine part or the like, the IC card This is insufficient in terms of reliability due to the deviation of the angle. In addition, the reading / writing of the IC card and the reader / writer must be performed in the vicinity of the card, which may be difficult to adopt in the mechanical component distribution process.

An object of the present invention is to provide a packaging weight management system that can easily and reliably manage the weight of a packaging container containing articles.
Another object of the present invention is to increase the efficiency and reliability of the quantity inspection.
Still another object of the present invention is to simplify the management of the load weight of a truck.

The packaging weight management system according to the present invention comprises a weight measuring means (5) for measuring the weight of a packaging container (W) containing an article (w), and a non-contact reading of information attached to the packaging container (W). The weight writing means (6) for writing the weight which is the measurement result of the weight measuring means (5) to the IC tag (1) capable of being transferred, and the packing container (W) containing the article after the weight writing is used as a carriage Weight reading that reads the IC tag (1) of each packing container (W) at the time of loading or after loading in the article stacking body (11) loaded in plural in (10) and compares the read result with a predetermined management item. Contrast means (15, 24, 29) is provided.
According to the management system of this configuration, the measured weight of the packaging container (W) is written in the IC tag (1), so that the weight reading / contrast means (15, 24, 29) is located slightly away from the packaging container (W). Can also be read from, and the measured weight can be read. Therefore, the weight management of the packaging container (W) containing the articles can be easily and reliably performed.

The transport table (10) may be a pallet, in which case the means for loading is a palletizer (13). In this case, the pallet-loaded article loader (11) is carried on the truck (14).
The carrier table may be a truck (14). When the packaging container (W) is directly loaded on the truck (14), the transport table is a truck.

In the present invention, the weight reading comparison means is provided in the delivery center (23), and information on the number of articles to be received in each packing container (W) and the weight as a result of reading the IC tag (1), It is also possible to use a quantity inspection means (24) for judging whether or not the quantity matches the quantity scheduled for arrival.
If the information on the number of articles scheduled to be received is known, the weight of the packaging container (W) with the article can be determined by collating with the information on the weight of each article and the packaging container (W). Thus, the weight calculated from the quantity information and the weight obtained as a result of reading the IC tag (1) should be matched originally, and the quantity checking means (24) determines the match. The actual number of items can be inspected. Therefore, inspection with higher reliability can be performed as compared with the case of relying on a slip or the like.

Since the weight reading comparison means reads the actual value of the weight recorded on the IC tag (1), the actual weight to be loaded on the track can be found by the integration. For this reason, the load weight of the truck (14) can be easily managed and is highly reliable. Accordingly, it is possible to prevent exceeding the weight limit based on the calculated loading weight, and it is also possible to use it for calculating the fare of the truck (14).

The packing weight management system according to the present invention may include both the quantity inspection means (24) and the truck load weight management means (15) as the weight reading comparison means. For example, when the carrying table is a pallet (10) and the loading means is a palletizer (13), the quantity checking means (24) and the truck load weight management means ( 15). The incoming quantity inspection means (24) is provided in the distribution center (23), and compares the information on the incoming quantity of goods to be received in each packing container (W) with the weight as the result of reading the IC tag (1). Thus, it is determined whether or not it matches the number of arrivals scheduled to arrive. The truck load weight management means (5) calculates the load weight of the truck (14) on which a plurality of the article load bodies (W) are loaded.
In the case of this configuration, the weight information recorded on the IC tag (1) of the packaging container (W) can be used for both the quantity inspection and the management of the load weight of the truck (14).
