Description

  The present invention relates to an apparatus, method, and program for identifying a package using an electronic tag in order to sort packages that are sequentially conveyed on a conveyance line.

  Conventionally, in order to improve work efficiency in package sorting work and reduce work mistakes, a system for sorting packages by using an electronic tag instead of a bar code and reading information recorded on the electronic tag has been proposed. (See Patent Document 1). According to this conventional system, packages to be sorted, to which electronic tags having necessary information written therein are attached, are sequentially transported on the transport line. In addition, the carrier line is provided with an antenna that receives writing information of the electronic tag and an electronic tag information processing terminal that converts information received by the antenna into required information. Based on the required information sent from the electronic tag information processing terminal, the sorting information processing terminal determines the destination of the parcel and outputs gate control information of the determined destination. The gate control information output from the sorting information processing terminal is sent to the sorting device. Based on the gate control information, the sorting device opens the gate that is the destination.

  This system assumes that whenever an RFID tag write information is received by an antenna, each time a package enters the antenna communicable area, assuming that one package is within the antenna communicable area. The information written in the electronic tag of the package is read to determine the destination of the package. Therefore, for example, in the case where two packages are present in the antenna coverage area at the same time and the electronic tags of these two packages are simultaneously read by the antenna, which one of the detected electronic tags is Cannot be identified as belonging to the package.

  For this reason, in this conventional system, the packages must be transported so that the packages exist one by one in the communicable area of the antenna in accordance with the timing of receiving (scanning) the writing information of the electronic tag by the antenna. Thus, reliable sorting is not guaranteed. In other words, in this configuration, if the speed of the transport line increases and the interval between packages decreases, the occurrence rate of sorting errors increases, so the speed of the transport line is limited to a low speed and the interval between packages to be transported also increases. There is a problem that work efficiency is not so good.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The apparatus according to the present invention is used together with a package sorting device, and identifies packages to be sequentially transported on a transport line of the package sorting device for sorting.
FIG. 1 is a plan view showing a schematic configuration of an apparatus according to an embodiment of the present invention. In FIG. 1, the conveyance line 1 of the package sorting apparatus is composed of, for example, a belt conveyor. The apparatus according to the present invention includes a first luggage sensor 3 which is provided in the conveyance line 1 and measures the conveyance speed and the length in the conveyance direction of the luggage 2 and outputs the speed measurement value and the length measurement value. In this embodiment, the first luggage sensor 3 includes a pair of photoelectric tube sensors 10a and 10b arranged at intervals along the transport direction.

The apparatus of the present invention also has an antenna for communicating with the electronic tag 5 provided in the luggage 2 in the unique communicable area 4 arranged on the downstream side of the first luggage sensor 3 in the transport line 1. 6 is provided. Although the antenna 6 is not shown, it is preferable that the antenna 6 is attached to a square-shaped gate disposed around the transfer line 1 and is transported on the transfer line 1 to one leg of the gate. A first antenna portion disposed toward the side surface of the gate 2, a second antenna portion disposed toward the upper surface of the luggage 2 transported on the transport line 1 to the upper beam of the gate, A third antenna portion arranged on the leg toward the side of the luggage 2 conveyed on the conveyance line 1 and a bottom beam of the luggage 2 conveyed on the conveyance line 1 on the lower beam of the gate. In addition, the first to fourth antenna portions sequentially communicate with the electronic tag 5 in one scan by the reader. By configuring the antenna 6 in this way, the electronic tag 5 can be read with high accuracy even if the electronic tag 5 is placed in the luggage 2 in any posture. Is possible. In this case, it is necessary that the transport line 1 be configured to allow radio waves to pass.
When the carrier line 1 is configured to prevent the passage of radio waves, the antenna 6 is attached to a downwardly opened U-shaped gate disposed so as to straddle the carrier line 1. A first antenna portion arranged on one leg toward the side of the luggage 2 conveyed on the conveyance line 1 and an upper beam of the gate arranged on the upper surface of the luggage 2 conveyed on the conveyance line 1 And a third antenna portion arranged on the other leg of the gate toward the side surface of the luggage 2 conveyed on the conveyance line 1, and can be scanned once by a reader. It is preferable that the first to third antenna portions sequentially communicate with the electronic tag.

  The apparatus according to the present invention is further arranged on the downstream side of the first luggage sensor 3 in the transport line 1 and on the upstream side of the antenna 4, and the luggage measured by the first luggage sensor 3 is communicated with the antenna 4. A second luggage sensor 7 for detecting when the vehicle has entered the possible area 6 and outputting a luggage entry detection signal is provided. In this embodiment, the second luggage sensor 7 includes a pair of downstream photoelectric tube sensors 10 b that also function as a part of the first luggage sensor 3.

  The antenna 6 scans after receiving the scan start signal and before receiving the scan end signal, and detects the detection start signal and the detection end signal of the electronic tag 5 provided in the luggage 2 together with the read data. An output reader 8 is connected.

  A luggage / electronic tag identification unit 9 is connected to the first luggage sensor 3, the second luggage sensor 7, and the reader 8. The baggage / electronic tag identification unit 9 is composed of a computer, records the speed measurement value and the length measurement value from the first baggage sensor 3 for each baggage 2 to be transported, and the second baggage sensor 7. When a baggage entry detection signal is received, a scan start signal is sent to the reader 8, and the time in the area where the baggage 2 is in the communicable area 4 is calculated and recorded from the speed measurement value and the length measurement value. When the in-area existence time has elapsed from the time when the scan start signal is sent, the scan end signal is sent to the reader 8, the time when the detection start signal is received from the reader 8, and the time when the detection end signal is received, At the same time, the data read by the reader 8 is recorded. The package / electronic tag identification unit 9 further determines the entry time of the package 2 into the communicable area 4 and the existing time within the area when the package 2 passes through the communicable area 4 and the reader 8 Based on the detection start time of the electronic tag 5 and the detection time, it is determined whether the electronic tag 5 belongs to the package 2 or another package before and after the package 2, and the data read from the electronic tag 5 Is output as sorting information for the corresponding package.

2 and 3 are program flow diagrams according to one embodiment of the present invention. The program according to the present invention is installed in a computer constituting the package / electronic tag identification unit 9 of the apparatus shown in FIG.
Referring to FIG. 2, the program of the present invention first causes the computer to execute an initial setting procedure (step S1). This initial setting includes initialization of electronic tag information, initialization of package information, initialization of a reader, and the like. Next, the program causes the computer to execute a time setting procedure (initialization of time data) (step S2).

  Then, the program causes the computer to determine whether or not the package has passed through the upstream photoelectric tube sensor 10a (hereinafter referred to as “first sensor”) (step S3), and the first sensor 10a causes the package to pass. When detected, the computer is caused to execute an interrupt routine (registration of package information, recording of the first sensor passage time) (step S18). Next, the program causes the computer to measure the length in the package conveyance direction from the detection signal of the first sensor 10a (step S4).

  Thereafter, the program causes the computer to determine whether the package has passed through the downstream photoelectric tube sensor 10b (hereinafter referred to as “second sensor”) (step S5), and the second sensor 10b determines whether the package has passed. When detected, interrupt routine (registration of baggage information, recording of second sensor passage time, measurement and recording of baggage speed, recording of baggage length, calculation and recording of in-area time, scan end time Calculation and recording, and determination time calculation and recording) are executed (step S19).

  In step S19, the baggage speed is obtained by calculation from the first sensor passage time (step S18) and the second sensor passage time (step S19), the distance between the first sensor and the second sensor, and the baggage length (step S4). It is done. The in-area existence time is obtained by calculation from the baggage speed (step S19), the baggage length (step S4), and the length of the communicable area, and the scan end time is obtained after the in-area existence time has elapsed from the scan start time. It is calculated as time.

  Next, the computer sends a scan start signal to the reader 8 (step S6), and the detection start time of the electronic tag output from the reader 8 as a result of the reader 8 scanning within the area existing time. Then, the detection end time and the data read from the electronic tag during that time are recorded (registration of electronic tag information) (steps S7 and S8).

When a predetermined time elapses after the luggage 2 passes through the communicable area 4 and the determination time is reached, the computer executes a determination routine (step S9).
FIG. 3 is a flowchart of the determination routine. Referring to FIG. 3, when the determination time is reached (step S10), the computer for all electronic tags registered in step S7 (step S15), for each electronic tag (step S11), Whether the electronic tag belongs to the package, or another package before and after the package, based on the entry time of the package into the communicable area and the existing time in the area and the detection start time and detection time of the electronic tag (Step S12, S13). After the determination, the registration information of the electronic tag is deleted (step S14), and the data read from the electronic tag is output as sorting information related to the corresponding package (step S16). Thereafter, the registration information related to the package is deleted (step S17).

  Next, a verification experiment using the apparatus shown in FIG. 1 was performed. In this experiment, the length of the package to be transported (L4 in FIG. 1) is set to 60 to 80 cm, the antenna 6 having the communicable area 4 (L3 in FIG. The second sensor 10b was arranged on the upstream side of the communicable area 4 with a distance of 20 cm (L2 in FIG. 1). The area between the second sensor 10b and the communicable area 4 is set as a dead area, and it is detected that the package / electronic tag identification unit 9 activates the reader 8 after it is detected that the package has passed the second sensor 10b. This is the region that absorbs the delay time. Moreover, the 1st sensor 10a was arrange | positioned on the upstream of the 2nd sensor 10b in the conveyance line 1 at a distance (L1 of FIG. 1). Furthermore, the time from when the package leaves the communicable area to the determination time is 500 ms. That is, if the transport speed of the load is 130 m / min, the distance from the rear end of the load leaving the communicable area until the front end of the load reaches the determination point (J in FIG. 1) is about 108 cm.

  Using this experimental apparatus, containers (packages) were sequentially transported on the transport line 1 in the arrangement as shown in FIG. In FIG. 4, containers W1 to W5 are arranged in a row with a spacer E (length L7 = 40 cm) in between. The first container W1 has an electronic tag P1 at the rear thereof, the second container W2 has no electronic tag, and the third container W3 has an electronic tag at the front thereof. P2, an electronic tag P3 is placed at the rear, an electronic tag P4 is placed at the rear of the fourth container W4, and four electronic tags P5 are placed at the center of the fifth container W5. ~ P8 is placed diagonally. In this case, the third container W3 is configured by connecting two containers, and the electronic tag P4 of the fourth container W4 is placed in a state of leaning substantially vertically.

Then, the packages are sequentially conveyed by the conveyance pattern shown in FIG. 4, and the resulting data is shown in the graph of FIG. In the graph of FIG. 5, the horizontal axis represents time (unit: ms). In FIG. 5, horizontal bar graphs W1 to W5 represent the in-area existence times of the containers W1 to W5, respectively, and horizontal bar graphs P1 to P8 represent the detection times of the electronic tags, respectively. J1 to J5 represent determination points regarding the containers W1 to W5, respectively. As can be seen from FIG. 5, at the determination point J1, the electronic tag P1 is within the area existence time of the container W1, but the container W2 is not within the area existence time (the container W2 enters the communicable area). It is determined that the electronic tag P1 belongs to the container W1. In addition, although the electronic tags P2 and P3 are detected at the determination point J2, since none of the electronic tags is within the area within the area of the container W2, the electronic tag P2 leaves the communicable area of the container W2. It is determined that there is no electronic tag in the container W2.
In FIG. 5, the detection times of the electronic tag P4 and the electronic tag P5 overlap, and are detected simultaneously during one scan. However, the electronic tag P4 is determined to be W4 by the determination at the determination point J4. It is determined that the electronic tag P5 belongs, and the electronic tag P5 is determined to belong to W5 by the determination at the determination point J5. Thus, even when a plurality of electronic tags belonging to two different containers are detected at the same time, it is reliably determined which container each electronic tag belongs to.

  In this way, according to the present invention, the time of entry of the antenna of the package that is sequentially conveyed into the communicable area and the existing time in the communicable area, the detection start time and the detection time of the electronic tag provided in the package, By comparing and contrasting, it is possible to accurately determine which package each electronic tag belongs to, that is, accurately identify the package.
