Description

  The present invention relates to a weighing and selling system that, for example, separates products into trays and the like by self-service at a bakery or the like and performs settlement at a cash register.

Conventionally, in a retail store such as a bakery, a system has been used in which convenience is improved when a customer purchases a product such as bread on a tray using a tool.
For example, Patent Document 1 discloses a weighing and selling system that measures and sells an amount of products that a customer desires to purchase by self-service in a supermarket or the like.
In this weighing and selling system, the purchaser has a shopping card for recording information such as weight data and price of the product sold by weight, and only when the shopping card is detected by the shopping card detection means, By making it possible to separate the products, unauthorized weighing and purchase due to a mismatch between the actually purchased product and the price label attached thereto is prevented.
Japanese Patent No. 3371821 (registered on November 22, 2002)

However, the conventional measurement and sales system has the following problems.
In other words, in the system disclosed in the above publication, in order to prevent unauthorized weighing, it is necessary for all purchasers to have a shopping card and to pass the shopping card through a detector for each purchase. The work at the time of purchase was complicated.

  An object of the present invention is to provide a weighing and selling system capable of performing an accurate settlement process while reducing a burden on a purchaser when purchasing a product without using a shopping card or the like.

  The weighing and selling system according to the first invention includes a plurality of weighing units, an information holding unit, and a reading unit. A plurality of products are placed on the weighing unit, and the entire product is weighed. Each information holding unit is attached to a tool for separating products from the weighing unit, and identification information is recorded individually. The reading unit reads the identification information recorded in the information holding unit when the measurement value in the measurement unit varies.

Here, a change in the measured value in the weighing unit when a product placed on a plurality of weighing units is separated using a predetermined tool is detected and recorded in an information holding unit attached to the tool The reading unit reads identification information unique to each gripper.
Normally, in a sales system in which products are sorted by such a self-service and then settled at a cash register, a store clerk performs settlement while visually confirming the sorted products on a tray or the like. For this reason, the conventional sales system has problems such as a calculation error due to a check mistake of a store clerk and a checkout failure.

  In the weighing and selling system of the present invention, for example, in a bakery or the like that employs a purchasing system that separates bread to be purchased using a single handle into trays and the like, from a platter on which a plurality of breads are arranged by a predetermined holder When the weighing value in the weighing unit located below the platter fluctuates when separating the bread into the tray, information such as the wireless tag attached to the fixture by the reading unit located on the side of the platter The identification information recorded in the holding unit is read.

  Thereby, in accordance with the timing of fluctuation of the measurement value in the measuring unit, the reading unit accumulates the type (unit price) of bread and the number of pieces and identification information of the holding device that are separated using a specific holder. Can do. As a result, the cash register can efficiently perform accurate settlement processing after recognizing the type and number of breads sorted from the platter to the tray based on the information accumulated in these reading units.

A weighing / sale system according to a second invention is the weighing / sale system according to the first invention, and the reading unit is connected to a cash register for settlement of the separated goods.
Here, a reading unit that reads identification information recorded in the information holding unit each time a product is separated from a platter or the like using a handle is directly or indirectly connected to the cash register.
This eliminates the need for collecting and collecting the identification information stored in the reading unit, so that the checkout process at the register can be performed smoothly. Then, the identification information read at this time can be sent to the cash register together with the product information (type, unit price, number) and the like to the cash register for settlement. As a result, when the checkout is made at the cash register, the checkout process can be performed accurately only by reading the product information corresponding to the identification information of the fixture.

A weighing and selling system according to a third invention is the weighing and selling system according to the first or second invention, and the weighing unit is connected to a cash register for paying out the separated goods.
Here, when the measured value fluctuates when the product is separated by the tool, information such as the product type, unit price, number of items, etc., for the cash register directly or indirectly connected to each weighing unit Send.
As a result, on the register side, in addition to the identification information of each tool acquired by the reading unit, information such as the type (unit price), the number, and the measured value of the goods separated by the tool is received from the measuring unit. Can be received. As a result, it is possible to easily recognize the type and number of products to be purchased and perform high-accuracy settlement processing simply by confirming the identification information of the tool.

  A metering and selling system according to a fourth invention is the metering and selling system according to the third invention, and the cash register has a metering device that weighs the entire product to be settled.

Here, it has a measuring device for measuring the weight of the entire product to be settled at the cash register.
Thus, for example, when the payment is made in a state where five types of bread are taken one by one in the tray, the weighing result, that is, when the bread is taken from the five weighing units on which the five types of bread are placed. Each reduced weighing value is sent to the cash register. As a result, the clerk at the cash register checks the products one by one by placing the five breads received from the customer on the weighing device, weighing the total weight, and comparing it with the total measured value received from each weighing unit. Without re-working, it is possible to easily check whether there is any bread that will not be settled.

  A weighing / sale system according to a fifth invention is a weighing / sale system according to any one of the first to fourth inventions, wherein a product separated by a gripper is returned to a position on a weighing unit. In the weighing unit, the increment of the measured value of the product and the identification information of the fixture are compared with the measured value of the product and the identification information of the fixture already acquired in the reading unit, A determination unit that determines whether the product can be returned is further provided.

Here, when the product once separated into a tray or the like is returned to the original measuring unit again, the identification information of the gripper is compared with the measured value to determine whether or not the processing for returning the product can be performed. judge.
As a result, if it is determined as possible as a result of the determination by the determination unit, for example, the product data corresponding to the identification information that has already been transmitted to the cash register is canceled, and the settlement is performed even though the data is restored. Can be prevented from being added. On the other hand, when the determination unit determines NO, it is possible to prevent the occurrence of problems such as returning different types of products onto the weighing unit, for example, by sounding a warning sound.

A weighing / sale system according to a sixth invention is a weighing / sale system according to any one of the first to fifth inventions, and issues a warning when a plurality of identification information is simultaneously read by a reading unit. An alarm unit is further provided.
Here, because a plurality of tools approached the reading unit placed on the side of the weighing unit etc. at the same time, when a plurality of identification information is read, an alarm such as an error sound is given to the customer. To emit.

  This prevents multiple weighing information from being read before the weighing value stabilizes at the time of sorting, and prevents accurate weighing values from being obtained and it is not possible to determine which product has been sorted. can do. As a result, when separating the products, by always reading only one piece of identification information, it is possible to accurately recognize which remover, that is, which customer has separated the product.

  A measuring and selling system according to a seventh aspect includes a plurality of measuring units, an information holding unit, and a writing unit. A plurality of products are placed on the weighing unit, and the entire product is weighed. The information holding unit is attached to each of the tools for separating the products, and information on the products separated by the tools is recorded. When the measurement value in the measuring unit varies, the writing unit writes information relating to the product separated by the gripper in the information holding unit.

Here, the variation of the measurement value in the weighing unit when the product placed on the plurality of weighing units is separated using a predetermined tool is detected, and each information holding unit attached to the tool is detected. Information such as the type (unit price) of the product, the number of items separated is written.
Normally, in a sales system in which products are sorted by such a self-service and then settled at a cash register, a store clerk performs settlement while visually confirming the sorted products on a tray or the like. For this reason, the conventional sales system has problems such as a calculation error due to a check mistake of a store clerk and a checkout failure.

  In the weighing and selling system of the present invention, for example, in a bakery or the like that employs a purchasing system that separates bread to be purchased using a single handle into trays and the like, from a platter on which a plurality of breads are arranged by a predetermined holder When the weighing value in the weighing unit located below the platter fluctuates when separating the bread into the tray, information such as the wireless tag attached to the gripper by the writing unit located on the side of the platter Information related to the separated product is written in the holding unit.

  As a result, product information related to the type (unit price), number of bread, etc., of the bread that has been sorted by the writing unit by the writing unit is stored in the information recording unit in accordance with the timing of fluctuation of the measurement value in the weighing unit. Can continue. As a result, the cash register recognizes the type and number of breads distributed from the platter to the tray based on the information about the products stored in the information recording unit attached to each gripper, and performs an accurate checkout process. It can be done efficiently.

  According to the weighing and selling system of the present invention, the cash register recognizes the type and number of products distributed from the weighing unit to the tray or the like based on the information accumulated in the reading unit, and is accurate and efficient. Checkout processing can be performed.

I do. Then, if there is a matching weighing result as a result of the above determination, the POS register 20 performs a settlement process for the divided bread based on the identification numbers transmitted from the readers R1 to R4. The configuration of the POS register 20 will be described in detail later.

  As shown in FIG. 3, in the bread shears E, a wireless tag 11 in which a unique identification number is recorded for each bread shear E is attached to the inner surface side of the grip portion. A plurality of bread scissors E are arranged near the entrance of the store together with the tray t. Each customer who wants to purchase bread takes one by one and uses the bread scissors E to obtain the bread he wants. It shall be arranged on the tray t from the tops 1 to 4.

[Configuration of each part constituting the weighing and selling system 100]
(Composition of Hakari 1)
As shown in FIG. 1, the peel 1 is included in the subtraction weighing system 10 and measures the bread placed on the display tray T1 placed on the peel 1. As shown in the figure, it has a substantially rectangular parallelepiped main body 1a, a communication port 1b (see FIG. 4), an alarm lamp (alarm unit) 1c, a display 8, a weighing platform 9, and a reader R1. Yes.

The main body 1a is configured to include a weighing table 9 for detecting the weight of a plurality of pans placed in the display tray T1, and a load cell (not shown) provided below the weighing table 9. Yes.
As shown in FIG. 4, the communication port 1b is connected to a communication port 18 mounted in the POS register 20 described later, and is unique to each measurement result and information on the product name and the like in bread cricket 1 and bread shears. The identification number is transmitted to the POS register 20 side. In addition, also in other cracks 2 to 4, information such as measurement results and product names is transmitted from the communication ports 2 b to 4 b to the communication port 18 mounted in the POS register 20.

The alarm lamp 1c turns on the lamp and issues an alarm when a plurality of identification numbers are read by the reader R1, which will be described later, until the measured value in the crack 1 is stabilized.
The display 8 is a color liquid crystal display excellent in visibility, and is attached to the side surface of the main body 1a, and displays information such as product name and unit price to the customer. The display 8 is provided with a product name display unit 8a and a price display unit 8b.

The price display unit 8 b displays the unit price “120” yen of the products placed on the display tray T <b> 1 on each peel 1.

The reader R1 is disposed on the side of the main body 1a, and reads the identification information of the bread shears E from the wireless tag 11 when the measured value of the bread placed on the weighing table 9 fluctuates by a predetermined amount or more.
In FIG. 2, the description is given by taking Hakari 1 as an example, but since the other Hakari 2 to 4 have the same configuration, the description of the configuration of the individual Hakari 2 to 4 is omitted here. To do.

(Configuration of POS register 20)
As shown in FIG. 4, the POS register 20 includes a weighing unit (metering device) 15, a display 16, a reader 17, a communication port 18, and a control unit (determination unit) 70.
The weighing unit 15 measures the total weight of the bread that the customer has placed on the tray t at the time of payment.

The display 16 is a touch panel type liquid crystal display, and is used when displaying the product name and price at the time of payment, or when the store clerk manually inputs the product name and price.
The reader 17 is provided on the upper surface of the POS register 20 for reading the identification number of the bread shears E at the time of payment. For this reason, when the customer moves to sort out all the bread he / she wishes to purchase and pays it to the POS register 20, the store clerk receives bread shears E from the customer and brings the portion of the wireless tag 11 closer to the reader 17. Thus, an identification number unique to each bread shear can be read.

  The communication port 18 is connected to the communication ports 1b to 4b mounted on each of the anchors 1 to 4. And when the fluctuation | variation of the measured value more than predetermined amount is detected in each crackle 1-4, and the identification number of bread shears E will be read in reader | leader R1-R4, the brand name and unit price on the crackle 1-4 will be read. The information regarding the reduced measurement value is transmitted to the communication port 18 of the POS register 20 from the communication ports 1b to 4b of each of the anchors 1 to 4 together with the identification number of the bread shears E.

The control unit 70 includes a CPU 71, a ROM 72, and a RAM 73. The control unit 70 reads various programs and data (for example, a settlement target product table 73a) stored in a storage unit such as the ROM 72 and the RAM 73, and the like via a LAN. Control of the operation of each connected device, settlement processing described later, and the like are executed.
The payment target product table 73a is stored in the RAM 73, and as shown in FIG. 5, the identification number of the bread shears E transmitted from each of the cracks 1 to 4, the product name, the unit price and weight for each product. It is recorded in an organized state. For this reason, in the control part 70, the payment object goods recorded here are read for every identification number at the time of payment, and a payment process is performed.

<Procedure for payment processing by the weighing and selling system 100>
The flow of the settlement process in the weighing and selling system 100 of the present embodiment will be described as follows using the flowchart shown in FIG.
That is, as shown in FIG. 6, first, in step S1, a customer who has visited the store receives bread shears E and a tray t installed near the entrance. Then, when the customer sorts the favorite bread while walking in the store, in step S2, the control unit 70 uses the bread shears E on the subtraction weighing system 10 side to transfer from the tops 1 to 4 to the tray t. It is detected that the separation has started, that is, that the measured value in Hakari 1 to 4 has fluctuated by a predetermined value or more.

Then, in step S3, the control unit 70 reads the identification number from the wireless tag 11 attached to the bread shears E by the readers R1 to R4 connected to the peels 1 to 4 whose measured values have fluctuated. The identification number is transmitted from 1 to 4 to the POS register 20.
At this time, in step S4, it is determined whether a plurality of identification numbers are read almost simultaneously by one reader R1 to R4. Here, when a plurality of identification numbers are read at the same time by one reader R1 to R4, it is not possible to know which bread shears E have been used for the merchandise, and the settlement process can be performed normally. Since there is a possibility of disappearing, the process proceeds to step S11, and in step S11, the control unit 70 turns on the lamps in the alarm lamps 1c to 4c. On the other hand, when only one piece of identification information is read by one reader R1 to R4, it is in a state where normal settlement processing can be performed, and thus the process proceeds to step S5 as it is.

  Next, in step S5, the control unit 70 obtains information on the bread type (product name), unit price, number of pieces, and the measured value displayed on the extracted highlights 1 to 4 from the changed highlights 1 to 4. The data is transmitted to the POS register 20. At this time, in the case where there are a plurality of breads divided into trays t from the cracks 1 to 4, the control unit 70 compares the measured value of one piece of bread inputted in advance with the changed measured value. It is possible to recognize whether the individual has been separated. For example, when two cream breads are separated into the tray t at the same time, if the measurement value of one cream bread is 235 to 245 g, the measurement value in the crackle 1 should be 470 to 490 g. The number of breads that are easily separated can be recognized.

  Next, in step S6, the processing from step S2 to step S4 is repeated until all breads that the customer wishes to purchase are sorted into the tray t and the POS register 20 performs the settlement process. On the other hand, when the settlement process is performed in the POS register 20 in step S6, the process proceeds to step S7. Note that this determination is made depending on whether the store clerk actually received the bread shears E in the POS register 20 and read the identification number of the bread shears E.

Next, in step S 7, the store clerk receives bread shears E from the customer in the POS register 20 and reads the identification number in the reader 17.
In step S8, the total weight of all breads distributed on the tray t received from the customer is weighed.
Here, in step S9, if the total weight of the product corresponding to the identification number read in step S7 and the actual measured value measured in the POS register 20 are within a predetermined error range, normal It is determined that the state is correct, and the process proceeds to step S10. On the other hand, if the difference between the actual measurement value and the total of the measurement values calculated based on the received data is outside the predetermined error range, there is a product that is forgotten to be settled, or It is possible that the product is in an abnormal state, for example, the amount of merchandise that has not been sorted is settled. Therefore, in such a case, the process proceeds to step S12, and a warning screen is displayed on the display 16 of the POS register 20.

As a result, the clerk can recognize that there is a divergence between the product actually brought to the POS register 20 and the data to be settled. It can be processed so that it is confirmed and correct payment is performed.
<Process when returning the product>
Here, the process when returning the product once sorted to the tray t to the original peels 1 to 4 will be described with reference to the flowchart of FIG.

That is, in step S21, when the product is returned to the original cracks 1 to 4 and the measured value in the cracks 1 to 4 increases (varies) by a predetermined amount or more, the readers R1 to R4 of the cracks 1 to 4 are scanned in step S22. Acquires the identification number of the bread shears E used when returning the product.
Then, in step S23, in the control unit 70, there is a product that matches the identification number and the data of the measured value that matches the product returned to Hakari 1 to 4 and the increased measured value. Judgment is made. Here, when there is no match, it is considered that the returned cracks 1 to 4 are wrong or the weight value of the product is greatly different. Therefore, the process proceeds to step S26 and the returned product 1 to which the product is returned. In ~ 4, a warning sound is generated. On the other hand, if there is matching data, it is considered that the merchandise that existed in the cracks 1 to 4 has been returned to its original state, so that the process of returning the merchandise is permitted in step S24.

In step S25, the control unit 70 deletes the corresponding data portion from the payment target product table 73a stored in the RAM 73 so that the products returned to the original burrs 1 to 4 are not settled. .
Thereby, when returning from the tray t to the original peels 1 to 4, after confirming whether the return sticks 1 to 4 are correct and the size of the returned goods is the same, Data for which the product is allowed to be returned can be deleted from the settlement target product. As a result, even when there is a customer who has performed a process for returning the product, it is possible to efficiently perform a high-accuracy settlement process.

[Features of weighing and selling system 100]
(1)
As shown in FIG. 1, the weighing and selling system 100 according to the present embodiment distributes the products placed on the crackers 1 to 4 to the tray t by using predetermined bread shears E, and the POS register 20. If the measured value fluctuates by a predetermined amount or more in each of the cracks 1 to 4, the identification number is read from the wireless tag 11 attached to the bread shears E in the readers R1 to R4. .

  As a result, the identification numbers read by the readers R1 to R4 and the products of the cracks 1 to 4 whose measured values have decreased at that time, the unit price of the products, the magnitude of fluctuation of the measured values, etc. are transmitted to the POS register 20. Can be recorded. As a result, at the time of checkout, it is possible to recognize the products separated in the tray t by simply specifying the identification number of the bread shears E without taking the trouble of passing a shopping card etc. through the reader each time. Can be executed efficiently. Furthermore, since the process at the time of the checkout process is automated, the conventional work performed by the store clerk can be omitted, so that the number of store clerk can be reduced and the labor cost can be suppressed.

(2)
In the weighing and selling system 100 of the present embodiment, the readers R1 to R4 are connected to the POS register 20 via the communication ports 1b to 4b built in each of the anchors 1 to 4 as shown in FIG.
As a result, the identification number read by the readers R1 to R4 can be received automatically or by a request from the POS register 20 on the POS register 20 side. As a result, it is not necessary to collect the identification numbers of the bread shears E read by the readers R1 to R4 up to the readers R1 to R4, so that the POS register 20 performs a smooth settlement process. Is possible.

Further, the identification number read by the readers R1 to R4 is transmitted together with information such as the type, unit price, and number of the products separated from the cracks 1 to 4, so that the POS register 20 only reads the identification number. Thus, the settlement process can be easily performed.
(3)
In the weighing and selling system 100 of the present embodiment, as shown in FIG. 4, the cracks 1 to 4 on which products before being placed in the tray t are placed and the POS register 20 are connected via the communication ports 1 b to 4 b. It is connected.

  As a result, together with the identification numbers read by the readers R1 to R4, the information such as the type, unit price, number of goods, the changed measurement value, etc. displayed on the punctures 1 to 4 whose measurement values have changed are also sent to the POS register 20. Can be sent. As a result, since it is possible to easily specify a product that has been sorted using the bread shears E to which a specific identification number is assigned, the settlement process can be performed very efficiently.

(4)
In the weighing and selling system 100 of the present embodiment, as shown in FIG. 4, the POS register 20 is provided with a weighing unit 15 that measures the entire product brought on the tray t for payment. ing.
Thereby, when the customer has finished sorting out the products to be purchased and moved to the POS register 20, the total weight of the products sorted in the tray t can be measured. For this reason, the weighing result obtained here is compared with the total weight of the goods sorted by the specific bread shears E included in the information transmitted from each of the cracks 1 to 4 to the POS register 20. By determining whether or not the error is within a predetermined error range, it is possible to easily confirm whether or not there is an error in the information received in the POS register 20 before performing the settlement process. As a result, it is possible to prevent in advance a checkout or a checkout of unsorted products in advance, and a more accurate checkout process can be performed efficiently.

(5)
In the weighing and selling system 100 according to the present embodiment, when the process of returning the products that have been allocated to the respective trays t to the original peels 1 to 4 is performed, as shown in FIG. The identification numbers are read by the readers R1 to R4 of 1 to 4, and the data corresponding to the identification numbers are compared with the increased burrows 1 to 4 and the measured value increased there. And only when it matches, the process which returns goods to the original cracks 1-4 is permitted.

Thereby, when the process which returns to the original cracks 1-4 is permitted, the data of the product can be deleted from the settlement target product table 73a. As a result, since the product returned to the correct position in the original state can be prevented from being settled, the settlement process in such a case can also be performed accurately.
(6)
In the weighing and selling system 100 of the present embodiment, when the measured value fluctuates by a predetermined value or more in any of the cracks 1 to 4, the corresponding reader R1 to R4 performs reading of the identification number of the bread shears E. In the case where a plurality of identification numbers are read before the measured values in the crisps 1 to 4 are stabilized, the alarm lamps 1c to 4c in the crisps 1 to 4 as shown in steps S4 and S11 in FIG. Lights up.

As a result, it is possible to prevent in advance from knowing which bread shears E have separated the products, and bread shears E in which the products have been separated from one hakari 1-4, that is, the bread shears. Customers who use E can be clarified. As a result, it is possible to more effectively and accurately perform accurate settlement processing.
(7)
In the weighing and selling system 100 of the present embodiment, as shown in FIG. 3, the wireless tag 11 is used as an information holding unit that records a unique identification number for each bread shears E.

Thereby, the readers R1 to R4 can read the information recorded in the wireless tag 11 when the bread shears E approach. As a result, the weighing and selling system 100 capable of automating the settlement process can be constructed using relatively inexpensive means.

In the above embodiment, as identification information unique to each bread shear E recorded on the wireless tag 11 attached to the bread shear E, an identification number consisting of alphanumeric characters is taken as an example as shown in FIG. Explained and explained. However, the present invention is not limited to this.
For example, a figure, a symbol, etc. can also be used as identification information. Alternatively, a combination of figures and symbols and alphanumeric characters can be used.

(G)
In the embodiment described above, the example using the bread shears E has been described as the attachment for attaching the wireless tag 11 as the information holding unit. However, the present invention is not limited to this.
For example, when the store adopting the present metering system is a cake shop, the products may be separated using a tool such as tongs suitable for sorting the products of the store. Even in this case, it is possible to obtain the same effect as described above by attaching an information holding unit such as a wireless tag to each handle.

(H)
In the above embodiment, an example in which products are arranged and sold in the display trays T1 to T4 placed on the crackles 1 to 4 has been described. However, the present invention is not limited to this.
For example, the products may be arranged directly on the weighing table 9 of the crackles 1 to 4 without using the display trays T1 to T4. In this case, it is more preferable that the shape of the weighing platform 9 of the cracks 1 to 4 is made into a tray shape. Thereby, even when the display tray is not placed on the cracks 1 to 4, it is possible to prevent the product from falling from the cracks 1 to 4.

(I)
In the above embodiment, the subtraction weighing system 10 and the POS register 20 constituting the weighing and selling system 100 of the present invention transmit and receive information such as the type of product and the weight value via the communication ports 1b to 4b and 18. An example was given and explained. However, the present invention is not limited to this.

For example, a configuration in which information such as a product name and a weight value is transmitted and received via a cable or the like for connecting the subtraction weighing system 10 and the POS register 20 to each other may be used.
(J)
In the above-described embodiment, when a plurality of identification numbers are acquired in one reader R1 to R4 at the time of product separation from the trays T1 to T4 for display placed on the crackles 1 to 4 to the tray t, The alarm lamps 1c to 4c are turned on to give an example of notifying a customer or a store clerk. However, the present invention is not limited to this.

For example, in addition to notification by turning on the alarm lamps 1c to 4c, notification may be performed by generating a warning sound. Or you may use combining the lighting of a warning lamp and generation | occurrence | production of a warning sound.
