Abstract

Goods (1) purchased in a store are located on a check out unit (2) and have the product details scanned (4). The data includes an identification number, price, weight, etc., and is transmitted to an on-line computer (7). The check out unit allows the gross weight of all purchases to be obtained and supplied to the computer. The scanned data provides gross weight values that are summed and used for comparison. If the difference lies within a defined tolerance band the transaction is considered correct. However, if the value difference lies outside either articles have not been registered or have been double entered.

Description

The invention relates to a method for detecting defective goods and inputs according to the preamble of claim 1 and is to avoid errors in the detection and Billing can be used in the sale of goods u. a. in retail, wholesale and in industrial data acquisition, preferably weight data acquisition.

When selling goods, it is common for the customer's z. B. in one Goods taken from the food chain by the customer himself or at the checkout of Cash register staff is scanned using the scanner cash register respective EAN number is recorded and by means of this and / or in addition in one IT unit deposited Dafen, which u. a. the article number, the price, the Contain weight or price / kg, the settlement is made.

The disadvantage of such recording and billing is that the Registration of the goods, the scanning of the articles is faulty.

It is conceivable that articles are not recorded or are recorded twice. Around Solutions are to be remedied by trading companies to overcome this disadvantage known who keep the error rate low by means of random checks and checks, this method is uncomfortable for the customer and an unrecognized one Goods issue or double entry of the goods issue does not exclude.

There is also a solution in the magazine "Wirtschaftswoche" No .: 16 04/11/1996 "More convenient shopping" known after which the customer made his purchases itself detected by typing or scanning the goods data on the Checkout is not applicable. The customer receives a chip card with his personal Data. Using a mobile terminal, which is located on the shopping cart, and a data acquisition unit with laser scanner, each item and its price can be registered using the barcode in the form of chip card data. A display shows the current subtotal at the push of a button.

At the exit, the customer puts the terminal back in a special holder. The data is transferred to a computer that prints a receipt. Samples are designed to ensure that customers enter all items. Here too the above disadvantage is that manual controls are required.  

According to the document US 4787467 is a method for the detection of defective goods exits and arrivals known, according to which goods receipt- Units whose total weight is determined from the individual goods by scanning the goods code, e.g. B. Barcode, EDP-appropriate the goods weight determine individually and in their entirety. This is done by the use of a scanner unit and by weighing processes under Taking into account the gross weight of the goods receiving unit, the weight the empty goods container and the individual goods through successive differential weighing. On the receipt, the price, the gross weight of each individual product and that Gross weight of the goods receiving unit can be seen. Based on the receipt the comparison of the measured gross weight with the measured and / or over Total weight determined from the individual components of the goods and EDP Goods receiving unit with subsequent case handling.

The disadvantage of this solution is that a coupling of several systems in Connection with a legally valid recording and storage of goods and -inputs in individual units, as well as data transmission in the LAN and WAN, optionally by radio, is not given.

According to the publication DE 44 33 913 C1, a calibration capability is Measured data determination device known. The disadvantage of this solution is in that the measured value determination device is arranged stationary and no case assessment can be made in the event of differences.

The object of the invention is to provide a method for detecting defective ones To develop goods receipts and receipts, which is an IT-compatible, verifiable and legally binding recording, billing, transfer and archiving by means of fixed or mobile as well as autonomous or grouped registration units enables the data transfer from the registration units to the EDP System should also be done wirelessly.

According to the invention the object is that specified in claim 1 Features resolved.  

Preferred developments of the invention result from the subclaims.

The advantages of the invention are

• - That an automatic determination of non-recorded and double recorded Goods issues are shown,
• - that the data determined, which may not be subject to custody or custody transfer, be calibrated,
• - That the data record in addition to the measured values from the reference number with secret Polynomials, a consecutive number, which is the unique assignment for ensures the time of operation in legal-for-trade traffic (year, weekday, Scale number etc.) and consists of the check number,
• - that the measurement processing is uninterrupted,
• that the tamper-proof archiving of the measured value data is given,
• - that third-party access to the verifiable memory is blocked,
• - That the measured value data on the verifiable storage medium is not provided by third parties can be deleted
• - that measured value data that is subject to verification and not subject to verification by means of a cross network a measured value data acquisition device from a computer workstation to one are transferable to others,
• - That measured value data is fed and processed in real time for EDP processing will,
• - That a larger throughput of measured data, especially with continuous weighing (Weighing with the conveyor belt running through) is possible without sources of error,
• - That the measured value data online in a separate window on a screen as Additional display or as the main display for additional measuring devices and that a legal and legal recording, billing, Transfer and archiving by means of fixed or mobile as well as autonomous or grouped acquisition units, the data transmission from the registration units for the EDP system can also be wireless.

The invention is based on the

• - Fig 1 as an exemplary embodiment of the determination of the total weight of each product item with evaluation and control.
• - Fig. 2 as an exemplary embodiment for a calibratable capturing and storing determined custody and / or not requiring calibration,
• - Fig. 3 shown as an embodiment of a cross-linked verifiable data.

According to Fig. 1, the total weight of all goods 1 x₁ to x _n before / after the detection by means of measurement data acquisition device 2 determines, with the gross weight of the goods-receiving unit 3 is also included in the total gross weight. By means of scanner unit 4 , the data per item 1 , z. B. EAN address code, article number, price, weight and / or price per unit of measurement and gross weight of the goods receiving unit 3, etc., contains and / or by radio connection 5 or direct connection 6 ON-LINE with a computer 7 is in operative connection, the data per goods 1 , z. B. EAN address code, article number, price, weight and / or price per unit of measurement and gross weight of the goods receiving unit 3 , the goods 1 are recorded and displayed according to individual items. Then the sum of the gross individual weights of the goods 1 corresponding to the sum of the individual prices per goods 1 , minus the gross individual weight of the goods receiving unit 3, is compared to the gross total weight of the goods 1 and shown on the document 8 in addition to the pricing , in that the document 8 rests on the document output 9 , the measured value data determination device 2 and the scanner unit 4 being operatively connected to one another and in each case to the computer 7 and the document output 9 .

If the difference is calculated from the sum of the gross individual weights of goods 1 minus the gross individual weights of goods receiving unit 3 , within the specified permissible tolerance range a _a to a _x , proof is provided that all goods 1 have been correctly picked up.

If the difference lies outside the tolerance range a _a to a _x with a negative sign, there is proof that not all goods 1 have been calculated, a new inclusion of goods 1 is necessary.

If the difference lies outside the tolerance range a _a to a _x with a positive sign, there is evidence that goods 1 have been calculated several times, a new inclusion of goods 1 is necessary.

For security reasons, the gross total weight of all goods 1 , including the gross individual weight of the goods receiving unit 3 , must be determined before or after the new acceptance. The till staff can make a manual decision about the correct entry of goods 1 .

At the same time, it is possible to provide a plurality of measured value data determination devices 2 as calibratable and / or non-verifiable measured value data determination devices 2 .

So it is also conceivable that the method for detecting defective goods exits and receipts can be used in such a way that the measured value data determination device 2 , z. B. to determine the total weight of all goods 1 , as an individually movable sub-system can be executed using suitable data connections, for. B. is connected online as a radio to the host computer. Such an arrangement enables a verifiable delivery of individual goods 1 to spatially and temporally distributed customers, as is the case with courier services and with the delivery of goods 1 in general, e.g. B. for freight forwarders. Furthermore, this arrangement enables the demonstrable recording of the current inventory of the sub-systems for control purposes, for. B. at customs.
