Description

Embodiments of the present invention relate to readers and programs.

Conventionally, in retail stores (stores) such as supermarkets, identification information such as a JAN (Japanese Article Number) code is read from a code symbol (bar code, two-dimensional code) attached to a product.

Further, conventionally, there is a reading device that transports a product by a belt conveyor or the like and reads the identification information attached to the product by a reading unit such as an imaging device installed in the middle of the transport path. In such a reading device, in order to prevent the identification information from being over-read, a device that reads the identification information by using a plurality of reading units has been proposed.

By the way, in the above-described configuration including a plurality of reading units, when one product is transported, the same identification information is read by each of the reading units. Further, even when products of the same type are continuously transported, the same identification information can be read by each of the reading units. In such a case, in order to prevent multiple registration of the products, the identification information read by each of the reading units is the identification information read from a single product or the identification information read from the separately transported products. It is necessary to determine whether or not.

However, in the conventional configuration, it is not possible to easily distinguish between a single product and a product of the same type transported separately, and the products are transported at a distance of a predetermined distance or more. Therefore, there was room for improvement in terms of efficiency.

An object to be solved by the present invention is to provide a reading device and a program capable of efficiently reading a product transported on a transport path.

The reading device of the embodiment includes a transport path, a detection unit, a plurality of reading units, and an output control unit. The transport path transports goods. The detection unit detects the product transported along the transport path. The reading unit is provided at different positions on the downstream side of the transport path from the detection unit, and reads identification information for identifying the product from the product transported on the transport path. The output control unit determines the time for the product detected by the detection unit to pass through each reading section of the reading unit, which is determined according to the positional relationship between the detection unit and the reading unit and the transportation speed of the transportation path. Based on the above, the identification information read by each of the reading units at the time of passing through the reading section is output as the identification information of the same product, based on the timing at which the product is detected by the detection unit.

Hereinafter, the reading device and the program according to the embodiment will be described with reference to the drawings. In the embodiment described below, an example applied to a product sales data processing system capable of executing sales registration and accounting processing of a product will be described. It should be noted that the present invention is not limited to the embodiments described below.

FIG. 1 is an external perspective view showing an example of a product sales data processing system according to an embodiment. As shown in FIG. 1, the product sales data processing system 1 includes a reading device 10 and a product sales data processing device 20.

The reading device 10 is an example of a reading device. The reading device 10 is a device that performs processing for reading identification information that identifies the type of the product H from the product H purchased by the customer. Specifically, the reading device 10 includes a product stand 11, a base 12, a loading platform 13, a belt conveyor 14, a detection unit 15, and a reading unit 16.

The product stand 11 is a stand on which the product H purchased by the customer is temporarily placed. The base 12 is a housing that connects the product stand 11 and the loading platform 13. The base 12 includes a belt conveyor 14 that moves from the product stand 11 toward the loading platform 13.

The loading platform 13 is a platform for packing the product H conveyed by the belt conveyor 14. The product H conveyed by the belt conveyor 14 is extruded and placed on the loading platform 13. For example, the customer can pack the product H placed on the loading platform 13 into a bag.

The belt conveyor 14 forms a transport path for transporting the product H from the product stand 11 to the loading platform 13. Specifically, the belt conveyor 14 is driven by a drive unit 108 (see FIG. 2), which will be described later, and moves in the transport direction of arrow A1 in the figure, that is, in the direction along the Y axis.

The detection unit 15 is an example of a detection unit. The detection unit 15 is arranged around the belt conveyor 14 and detects the product H conveyed on the belt conveyor 14. In FIG. 1, the detection unit 15 is arranged on one end side of both ends along the transport direction of the belt conveyor 14, and the arrangement posture is fixed so that the sensing direction (broken line arrow direction) faces the other end side. Then, the detection unit 15 detects the product H passing through its own sensing surface (the surface facing the belt conveyor 14) by sensing on the belt conveyor 14. The detection unit 15 can be realized by, for example, an object detection sensor using light or sound (ultrasonic waves).

The reading unit 16 is an example of a reading unit. The reading unit 16 is arranged on the downstream side of the belt conveyor 14 with respect to the detecting unit 15, and reads the identification information from the product H conveyed by the belt conveyor 14. Here, the identification information is a product code such as a JAN (Japanese Article Number) code, and means information capable of identifying the type of the product H.

FIG. 1 shows an example in which two reading units 16a and 16b are arranged on the downstream side of the detecting unit 15 as the reading unit 16. Here, the reading unit 16a and the reading unit 16b are arranged at different positions from each other. Further, FIG. 1 shows an example in which the reading unit 16a and the reading unit 16b are arranged above the belt conveyor 14, and the main reading direction (broken line arrow in the figure) is the surface of the belt conveyor 14, that is, below. Towards. In such a configuration, the reading units 16a and 16b read the identification information from above the product H conveyed by the belt conveyor 14.

The reading unit 16 can adopt a device configuration according to the type of medium that holds the identification information. For example, when the identification information is held in the code symbol attached to the product H, the reading unit 16 can be realized by a code scanner, an imaging device, or the like capable of reading the code symbol. In the configuration of FIG. 1, it is assumed that the product H is transported with the surface to which the code symbol is attached facing up. Further, for example, when the identification information is held in a wireless tag such as an RFID (Radio Frequency IDentifier) tag attached to the product H, the information is read by an RFID reader or the like capable of reading the information from the wireless tag. Part 16 can be realized.

The product sales data processing device 20 performs sales registration and accounting processing of the product H purchased by the customer based on the identification information read by the reading device 10. Specifically, the product sales data processing device 20 corresponds to the identification information read by the reading device 10 based on the product master in which the identification information of each product is associated with the product information such as the product name and price of the product. Identify product information for the product. The product sales data processing device 20 temporarily stores the identification information read by the reading device 10 and the product information corresponding to the identification information to register the sales of the product. Then, the product sales data processing device 20 calculates the total price of the product H purchased by the customer based on the product information of each product H registered for sales, and setstle the total price with the payment amount paid by the customer. Perform accounting treatment.

Next, the configuration of the reading device 10 will be described. FIG. 2 is a diagram showing an example of the hardware configuration of the reading device 10. As shown in FIG. 2, the reading device 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, and a RAM (Random Access Memory) 103.

The CPU 101 is an example of a processor, and controls the operation of the reading device 10 in an integrated manner. The ROM 102 stores various programs. The RAM 103 is a workspace for developing programs and various data. The CPU 101, ROM 102, and RAM 103 are connected to each other via the bus 104. The CPU 101, ROM 102, and RAM 103 constitute a control unit 100 of a computer configuration. The control unit 100 executes various processes by operating the CPU 101 according to the control program 105a stored in the ROM 102 or the storage unit 105 and expanded in the RAM 103. The control unit 100 is provided with a time measuring function such as an RTC (Real Time Clock) and a time measuring unit (not shown).

Further, the control unit 100 is connected to the storage unit 105 via the bus 104. The storage unit 105 is composed of an HDD (Hard Disc Drive), a flash memory, or the like, and maintains the stored contents even when the power supply is cut off. The storage unit 105 stores, for example, the control program 105a. The control program 105a is a control program for controlling the reading device 10.

Further, the communication unit 106 is connected to the control unit 100 via the bus 104. The communication unit 106 is a communication interface that can be connected to a network such as a LAN (Local Area network). The communication unit 106 communicates with the product sales data processing device 20, which is the output destination of the identification information, a store server (not shown), an information processing device installed in the service counter of the store, and the like.

Further, the control unit 100 is connected to the drive unit 108 in addition to the detection unit 15 and the reading unit 16 (16a, 16b) described above via the bus 104 and the input / output controller 107. The drive unit 108 controls the drive of the belt conveyor 14. Specifically, the drive unit 108 drives the belt conveyor 14 under the control of the control unit 100 to move the product H in the transport direction (A1 direction in FIG. 1).

Next, the functional configuration of the reading device 10 will be described. FIG. 3 is a diagram showing an example of the functional configuration of the reading device 10.

As shown in FIG. 3, the reading device 10 includes a detection result acquisition unit 111, a reading control unit 112, and an output control unit 113 as functional units. Even a part or all of these functional units may have a software configuration realized by cooperation between a processor (CPU 101) and various programs (for example, control program 105a) stored in a memory (ROM 102, storage unit 105). Good. Further, a part or all of these functional units may have a hardware configuration realized by a dedicated circuit or the like.

The detection result acquisition unit 111 is an example of the detection result acquisition means. The detection result acquisition unit 111 acquires the detection result of the detection unit 15. Specifically, the detection result acquisition unit 111 acquires information indicating the detection result of the product H from the detection unit 15.

The reading control unit 112 is an example of the identification information acquisition means. The reading control unit 112 controls the reading operation of the reading unit 16. Specifically, the reading control unit 112 operates the reading units 16a and 16b to acquire the identification information read by each of the reading units 16a and 16b. Here, the reading control unit 112 can determine which of the reading unit 16a and the reading unit 16b has read the identification information. In the case of an imaging device in which the reading unit 16 captures a code symbol, the reading control unit 112 may perform a decoding process for extracting identification information from the captured code symbol.

The output control unit 113 is an example of the output unit and the output control means. The output control unit 113 controls the output of the identification information acquired by the read control unit 112. Specifically, in the output control unit 113, the product H detected by the detection unit 15 is determined by the separation distance between each of the detection unit 15 and the reading unit 16 and the transport speed of the belt conveyor 14, and the product H detected by the detection unit 15 is the reading unit 16. The output of the identification information is controlled based on the time passed through each reading section.

Hereinafter, the operation of the output control unit 113 will be described with reference to FIGS. 4 to 7. Here, FIGS. 4 to 7 are diagrams for explaining the operation of the output control unit 113. Note that FIGS. 4 to 7 show a state in which the reading device 10 is viewed from the horizontal direction (X-axis direction).

As described with reference to FIG. 1, the detection unit 15, the reading unit 16a, and the reading unit 16b are arranged in this order from the upstream side (left side in the figure) to the downstream side (right side in the drawing) of the belt conveyor 14. Further, the reading unit 16a and the reading unit 16b are arranged so that the reading direction thereof is directed downward perpendicular to the surface of the belt conveyor 14, so that the reading sections R1 and R2 shown by the broken lines in the drawing are above the belt conveyor 14. It is formed. Here, the reading sections R1 and R2 mean an area in which each of the reading unit 16a and the reading unit 16b can read the identification information on the transport surface of the belt conveyor 14.

Further, since the arrangement positions of the detection unit 15 and the reading units 16a and 16b with respect to the belt conveyor 14 are fixed, the distance from the detection unit 15 to the reading sections R1 and R2 can be represented as shown in FIG. Here, the distance L1 means a separation distance from the detection unit 15 to the start position of the reading section R1. Further, the distance L2 means a separation distance from the detection unit 15 to the end position of the reading section R1. Further, the distance L3 means a separation distance from the detection unit 15 to the start position of the reading section R2. Further, the distance L4 means a separation distance from the detection unit 15 to the end position of the reading section R2.

Further, assuming that the moving speed (conveying speed) V of the belt conveyor 14 is constant, the time for the product H detected by the detection unit 15 to pass through the reading sections R1 and R2 is defined from the relationship between the distance and the speed. be able to.

Specifically, based on the time when the product H is detected by the detection unit 15, the time until the product H reaches the start position of the reading section R1 is L1 / V (hereinafter, T1), and the reading section R1. The time to reach the end position is L2 / V (hereinafter, T2). That is, the product H can be defined as passing through the reading section R1 between the time T1 and the time T2. Similarly, based on the time when the product H is detected by the detection unit 15, the time until the product H reaches the start position of the reading section R2 is L3 / V (hereinafter, T3), and the reading section R2. The time to reach the end position is L4 / V (hereinafter, T4). That is, the product H can be defined as passing through the reading section R2 between the time T3 and the time T4.

Hereinafter, the period from time T1 to time T2 is also referred to as "first period", and the period from time T3 to time T4 is also referred to as "second period". Further, it is assumed that the information indicating the first period and the second period (for example, time T1 to time T4) is stored in advance in the storage unit 105 or the like as setting information.

The output control unit 113 starts timing with the timing at which the product H is detected by the detection unit 15 as a base point. For example, as shown in FIG. 5, when the detection unit 15 detects the passage of the product H (H1), the output control unit 113 starts timing from the detected timing (corresponding to the time t0). Here, the time may be an absolute time such as standard time or a relative time such as a timer.

Further, the output control unit 113 derives the times t1 to t4 corresponding to the respective timings of the above-mentioned T1 to T4 with the time t0 as the base point. Here, the period of time t1 to time t2 corresponds to the first period. Further, the period from time t3 to time t4 corresponds to the second period. The time t5 means the end arrival time at which the end position of the belt conveyor 14 is reached. The end arrival time can be obtained by dividing the distance from the position of the detection unit 15 to the end of the belt conveyor 14 by the transport speed V. The output control unit 113 continues the time counting of the product H1 from the time t0 to the time t5.

Subsequently, it is assumed that the product H1 is conveyed to the position shown in FIG. 6 by the transfer to the belt conveyor 14. In this case, since the product H1 is included in the reading section R1, the identification information can be read by the reading unit 16a. Further, paying attention to the elapsed time from the base point, the identification information of the product H1 becomes readable in the first period of time t1 to time t2. When the identification information is read by the reading unit 16a, the output control unit 113 cooperates with the reading control unit 112 to associate the read identification information with the time (reading time) during timekeeping for the product H1. Temporarily memorize.

At this time, when the detection unit 15 detects the passage of another product H (H2), the output control unit 113 starts timing at the timing when the product H2 is detected (corresponding to the time u0). Further, the output control unit 113 sets the time u0 as a base point, and derives the times u1 to u4 corresponding to the respective timings of T1 to T4 described above from the time u0, similarly to the product H1. Here, the period of time u1 to time u2 corresponds to the first period, and the period of time u3 to time u4 corresponds to the second period. It should be noted that the timekeeping of the product H1 and the timekeeping of the product H2 shall be performed separately by an independent timer or the like.

Subsequently, it is assumed that the product H1 and the product H2 are transported to the positions shown in FIG. 7 by transporting to the belt conveyor 14. In this case, since the product H1 is included in the reading section R2, the identification information can be read by the reading unit 16a. Further, paying attention to the elapsed time from the base point, the identification information of the product H1 becomes readable in the second period from the time t3 to the time t4. When the identification information is read by the reading unit 16a, the output control unit 113 temporarily stores the read identification information in association with the reading time during timekeeping for the product H1 by cooperating with the reading control unit 112. ..

On the other hand, since the product H2 is included in the reading section R1, the identification information can be read by the reading unit 16a. Further, paying attention to the elapsed time from the base point, the identification information of the product H2 becomes readable in the first period of time u1 to time u2. When the identification information is read by the reading unit 16a, the output control unit 113 temporarily stores the read identification information in association with the reading time during timekeeping for the product H2 by cooperating with the reading control unit 112. ..

By the way, in the above-described configuration of the reading unit 16, when one product H is conveyed, the same identification information is read by the reading unit 16a and the reading unit 16b. Further, even when the product H1 and the product H2 continuously transported as shown in FIG. 7 are the same type of product H, the same identification information is read by the reading unit 16a and the reading unit 16b. In such a case, in order to prevent multiple registration of products, the identification information read by each of the reading units 16 is read from the identification information read from a single product H or from the separately transported products H. It is necessary to determine whether it is the identification information. Further, when the identification information cannot be read by all of the reading units 16 even though the existence is detected by the detecting unit 15, the customer or the clerk is asked to confirm whether or not the product H has actually been transported. There is a need.

Therefore, the output control unit 113 simply obtains the identification information read between the first period and the second period based on the time when the time counting is started each time the product H is detected by the detection unit 15. It is output as identification information read from one product (same product) H.

For example, in the example of FIGS. 5 to 7, the output control unit 113 sets the identification information read during the time t1 to the time t2 (first period) based on the reading time stored in association with the identification information. And the identification information read between the time t3 and the time t4 (second period) is output as the identification information of the product H1. Similarly, the output control unit 113 obtains the identification information read between the time u1 and the time u2 (first period) and the identification information read between the time u3 and the time u4 (second period). , Output as identification information of product H2.

As a result, the reading device 10 can output a single identification information to the product sales data processing device 20 for each product H conveyed on the belt conveyor 14, so that the identification information of the same product can be output multiple times. It can be prevented from being stored.

If the product H is detected by the detection unit 15 but the identification information is not read in either the first period or the second period, the output control unit 113 may use the product sales data processing device 20 or the product sales data processing device 20. By transmitting error information to other devices, the occurrence of an error is notified. The output control unit 113 may stop the drive of the belt conveyor 14 by controlling the drive unit 108 in response to the notification of the occurrence of an error.

As a result, the reading device 10 can determine and output whether the identification information read by each of the reading units 16 is a single product H or a separately transported product H. Further, in the reading device 10, when the identification information cannot be read by each of the reading units 16, the state can be detected and the occurrence of an error can be notified. Therefore, whether or not the product H has been over-read. It is possible to prompt customers and clerk to confirm.

Further, when the identification information read in the first period and the second period is different, the output control unit 113 suppresses the output of the identification information and notifies the occurrence of an error. As a result, the reading device 10 can prevent the product H from being registered as sales when a fraudulent act such as replacing the product H during transportation on the belt conveyor 14 is performed.

Further, when the identification information is read in either the first period or the second period, the output control unit 113 shall output the read identification information. For example, depending on the position and orientation of the product H placed on the belt conveyor 14, the reading accuracy of the identification information may decrease, so that the reading of the identification information may fail in the first period or the second period. .. In such a case, the output control unit 113 can save the trouble of re-reading the product H by outputting the identification information read in either the first period or the second period. , The efficiency of the reading process can be improved.

The product sales data processing device 20 registers the sales of the product H purchased by the customer based on the identification information output from the reading device 10. With the above-described configuration, the reading device 10 outputs one identification information for each product H conveyed on the belt conveyor 14, so that it is possible to prevent the sales registration of the product H from being performed multiple times. Therefore, by using the reading device 10 of the present embodiment, it is possible to improve the efficiency of sales registration and accounting processing executed by the product sales data processing device 20.

Hereinafter, the operation of the reading device 10 will be described with reference to FIG. Here, FIG. 8 is a flowchart showing an example of the reading process performed by the reading device 10. It is assumed that this process is executed every time the product H is detected by the detection unit 15.

First, when the product H is detected by the detection unit 15, the detection result acquisition unit 111 acquires the detection result (step S11). The output control unit 113 starts time counting related to the detected product H in accordance with the detection of the product H (step S12).

Subsequently, the output control unit 113 determines whether or not the identification information has been read by the reading unit 16 (step S13). Here, if the identification information has not been read (step S13; No), the process proceeds to step S15. When the identification information is read by the reading unit 16 (step S13; Yes), the output control unit 113 temporarily associates the identification information with the time when the identification information is read (reading time). It is memorized (step S14), and the process proceeds to step S15.

Subsequently, the output control unit 113 determines whether or not the time during timing has reached the end arrival time (step S15). Here, if the end arrival time has not been reached (step S15; No), the process returns to step S13. When the end arrival time is reached (step S15; Yes), the process proceeds to step S16. At this point, the product H has reached the end of the belt conveyor 14.

In the following step S16, the output control unit 113 refers to the reading time of the identification information temporarily stored in step S14, and determines whether or not the identification information read in the first period or the second period exists (step). S16). Here, when the identification information is not read in either the first period or the second period (step S16; No), the output control unit 113 outputs the error information (step S19) and ends the process.

According to the determination in step S16, the identification information read at times other than the first period and the second period is not output to the product sales data processing device 20, but is discarded.

If it is determined that the identification information has been read in the first period or the second period (step S16; Yes), is the output control unit 113 reading the identification information in both the first period and the second period? Whether or not it is determined (step S17). Here, when the identification information is read in either the first period or the second period (step S17; No), the output control unit 113 transmits the read identification information to the product sales data processing device 20. Output (step S20) and end the process.

When the identification information is read in both the first period and the second period (step S17; Yes), the output control unit 113 compares both the identification information read in the first period and the second period. Then, it is determined whether or not they match (step S18). Here, when both identification information do not match (step S18; No), the output control unit 113 outputs error information (step S19), and ends the process.

On the other hand, when both identification information match (step S18; Yes), the output control unit 113 outputs the identification information to the product sales data processing device 20 (step S20), and ends the process.

As described above, the reading device 10 is based on the timing at which the product H is detected by the detection unit 15, and the identification information read by the reading unit 16a in the first period and the reading unit 16b during the second period. The read identification information is output as the identification information of the same product.

As a result, the reading device 10 can output the identification information for each product H even when the products H of the same type are continuously transported. Therefore, the reading device 10 can save the trouble of transporting the product H at a distance of a predetermined distance or more, and can more reliably read the identification information, so that the product H can be read efficiently. Can be done.

The above-described embodiment can be appropriately modified and implemented by changing a part of the configuration or function of the reading device 10. Therefore, in the following, some modifications according to the above-described embodiment will be described as other embodiments. In the following, points different from the above-described embodiment will be mainly described, and detailed description of points common to the contents already described will be omitted. Further, the modifications described below may be carried out individually or in combination as appropriate.

(Modification example 1)
In the above-described embodiment, the embodiment in which the identification information is read by using the two reading units 16 has been described, but the number of reading units 16 is not limited to this. Further, the arrangement position and posture (reading direction) of the reading unit 16 are not limited to the above-described embodiment. For example, the reading unit 16a and the reading unit 16b may be arranged in different postures.

(Modification 2)
In the above-described embodiment, the output control unit 113 holds the identification information read by the reading unit 16 in association with the reading time, and the identification read in the first period and the second period from the held identification information. The form of extracting the information and outputting it as the identification information of the same product has been described. However, the method of outputting the identification information is not limited to this.

For example, the output control unit 113 reads only the identification information read during the first period and the second period from the timing when the time counting is started with the detection of the product H by cooperating with the reading control unit 112. The configuration may be obtained from the unit 16.

As a result, the reading device 10 can exert the same effect as that of the above-described embodiment, so that the product H can be efficiently read. Further, since the reading device 10 can limit the period during which the reading unit 16 reads the identification information to the first period and the second period, the identification information can be read at a time other than the first period and the second period. It is possible to prevent reading from being performed.

(Modification example 3)
In the above-described embodiment, the embodiment in which the reading unit 16 is constantly operated while the product H is being conveyed has been described. However, the present invention is not limited to this, and the reading unit 16 may be operated only while the product H passes through the reading section.

In this case, the reading control unit 112 operates the reading units 16a and 16b individually during the time corresponding to each of the first period and the second period by synchronizing with the time measured by the output control unit 113. As a result, the identification information can be read from the product H while the product H passes through the reading sections R1 and R2.

As a result, the reading device 10 can exert the same effect as that of the above-described embodiment, so that the product H can be efficiently read. Further, since the reading device 10 can limit the period during which the reading unit 16 reads the identification information to the first period and the second period, the identification information can be read at a time other than the first period and the second period. It is possible to prevent reading from being performed.
