Detailed Description
Hereinafter, an embodiment of the radio tag reading apparatus will be described in detail with reference to the drawings. The embodiment described below is an embodiment of the wireless tag reading apparatus, and is not limited to the configuration, the specification, and the like. The wireless tag reading apparatus of the present embodiment is an application example to a wireless tag reading apparatus that reads a wireless tag for stock management at the time of warehousing or ex-warehouse.
Fig. 1 is a perspective view showing an example of an external appearance of a wireless tag reading apparatus 1 according to the present embodiment. Fig. 2 is a side sectional view showing an example of an external appearance of the radio tag reading apparatus 1 according to the present embodiment. Fig. 3 is a main sectional view showing an example of an external appearance of the radio tag reading apparatus 1 according to the present embodiment.
The wireless tag reading apparatus 1 has a tunnel 10. The tunnel 10 has a first side 11, a second side 12 and an upper face 13. The first side surface 11 is disposed at a position opposite to the second side surface 12. Further, the first side 11 and the second side 12 stand substantially vertically with respect to the ground. Furthermore, the first side 11 and the second side 12 support the upper face 13. The upper surface 13 forms a ceiling (ceiling) of the tunnel 10.
Between the first side surface 11 and the second side surface 12, a passage is formed through which a flat car or the like on which an article to which a wireless tag is attached is placed passes. Thus, the wireless tag reading apparatus 1 has a passage inside the tunnel 10. The operator of the wireless tag reading apparatus 1 pushes the flat car on which the article to which the wireless tag is attached is placed, and thereby passes the flat car through the tunnel 10. The wireless tag reading apparatus 1 reads a wireless tag when the wireless tag passes through the inside of the tunnel 10.
Here, the wireless tag is a tag such as an RF (Radio Frequency) tag. The wireless tag has an IC (Integrated Circuit) chip for storing information and an antenna. The wireless tag performs reading and writing of information stored in the IC chip by performing wireless communication with the wireless tag reading apparatus 1. When the information stored in the IC chip is read, the wireless tag transmits the information to the wireless tag reading apparatus 1. For example, the wireless tag contains article information that can identify an article to which the present device is attached.
The wireless tag reading apparatus 1 includes a plurality of antennas for radiating radio waves for reading wireless tags inside the tunnel 10. More specifically, the wireless tag reading apparatus 1 includes a first antenna 21, a second antenna 22, a third antenna 23, and a fourth antenna 24 inside the tunnel 10. The first antenna 21 is provided on the first side surface 11 in the tunnel 10 substantially at the center in the conveyance direction of the articles placed and conveyed by the flatbed and lower than the center in the height direction of the tunnel 10. The second antenna 22 is provided in the tunnel 10 substantially at the center in the conveyance direction of the articles placed and conveyed by the flatbed and above the first side surface 11. The third antenna 23 is provided on the second side surface 12 of the tunnel 10, which is substantially at the center in the conveyance direction of the articles placed and conveyed by the flatbed and is lower than the center in the height direction of the tunnel 10. The fourth antenna 24 is provided in the tunnel 10 substantially at the center in the conveyance direction of the articles placed and conveyed by the flatbed and above the second side surface 12.
The first antenna 21, the second antenna 22, the third antenna 23, and the fourth antenna 24 radiate radio waves for reading the wireless tag in the tunnel 10. The first antenna 21, the second antenna 22, the third antenna 23, and the fourth antenna 24 receive radio waves having article information output from the wireless tag. In the following description, the first antenna 21, the second antenna 22, the third antenna 23, and the fourth antenna 24 will be referred to as the antennas 20 unless otherwise noted.
Here, when the respective antennas 20 simultaneously radiate electric waves. There are cases where the radio tags are not read due to interference of radio waves emitted from the antennas 20. Therefore, the radio waves are radiated from any one of the antennas 20 in a time-sharing manner from each of the antennas 20. In the present embodiment, a case where the wireless tag reading apparatus 1 has four antennas will be described as an example. However, the number of the antennas 20 may be five or more, or three or less.
The wireless tag reading apparatus 1 includes an entrance lock section 141 for closing the entrance of the tunnel 10 and an exit lock section 142 for closing the exit. Fig. 4 is a perspective view showing an example of an appearance of the entrance seal portion 141 of the wireless tag reading apparatus 1 according to the present embodiment in a closed state when viewed from the entrance side. Fig. 5 is a perspective view of an example of an appearance of the wireless tag reading apparatus 1 according to the present embodiment when the outlet seal section 142 is in a closed state as viewed from the outlet side. Hereinafter, the inlet seal portion 141 and the outlet seal portion 142 are referred to as the seal portion 14, unless otherwise specified. As shown in fig. 4 and 5, the locking portion 14 is a member that closes the entrance and exit of the tunnel 10. The locking portion 14 is formed of an electric wave shielding material that shields the electric wave radiated from the antenna 20. For example, the locking portion 14 is a shielding mesh (net) formed by forming a metal for shielding radio waves into a mesh shape. The locking portion 14 is not limited to the shielding mesh, and may be a metal plate having a hole or another member for shielding radio waves.
Here, a method of using the wireless tag reading apparatus 1 will be described in detail.
First, an operator using the wireless tag reading apparatus 1 inputs an article to be read by the wireless tag reading apparatus 1 to the wireless tag reading apparatus 1. That is, the operator inputs the object items to be put in or out of the warehouse into the wireless tag reading apparatus 1. Specifically, the wireless tag reading apparatus 1 receives an operation to specify the number of target articles and the target articles stored in the server or other devices.
Next, the radio tag reader 1 causes the antenna 20 to radiate radio waves in a time-sharing manner for a predetermined period. During this prescribed period, the operator pushes the flat car on which the article to which the wireless tag is attached is placed, and passes the flat car through the passage inside the tunnel 10. The wireless tag reading apparatus 1 reads a wireless tag passing through the inside of the tunnel 10 for a predetermined period.
The wireless tag reading apparatus 1 compares the designated target article with the article information read from the wireless tag, and determines whether or not there is an unread wireless tag. When the unread wireless tag is present for a predetermined period of time, the wireless tag reading apparatus 1 notifies that the unread wireless tag is present.
When the operator is notified of the presence of an unread wireless tag, the operator returns the cart to the inside of the tunnel 10, and then causes the wireless tag reading device 1 to read the wireless tag again. However, the wireless tag that failed in reading is in a state in which reading is difficult, so that the first reading fails.
Here, the wireless tag reading apparatus 1 includes a holding unit 30 (see fig. 6) that is detachably held by any one of the plurality of antennas 20. For example, the first antenna 21 is held by the holding portion 30. Thus, the operator can detach the first antenna 21 from the holding portion 30 and align the first antenna 21 with the radio tag that has failed to be read.
When the first antenna 21 is detached from the holding portion 30 and used, radio waves are radiated from the first antenna 21, and no radio waves are radiated from the second antenna 22, the third antenna 23, and the fourth antenna 24. By doing so, no interference occurs with the radio wave of another antenna. In other embodiments, when the radio tag whose reading has failed cannot be specified, the reading of the radio tag is performed again by all the antennas 20. By doing so, since radio waves are radiated from a plurality of antennas, the possibility that all the radio tags can be read becomes high.
Since the first antenna 21 is aligned, the wireless tag reading apparatus 1 can read even a wireless tag which is difficult to read. In the present embodiment, the case where the first antenna 21 is detachably held by the holding portion 30 (see fig. 6) is described as an example, but the second antenna 22, the third antenna 23, or the fourth antenna 24 may be detachably held by the holding portion 30. The plurality of antennas 20 may be detachably held by the holding portion 30.
In the present embodiment, at the time of initial reading, radio waves for reading the radio tag are radiated from the antenna 20 into the tunnel 10. In another embodiment, at the time of initial reading, radio waves may be radiated from the second antenna, the third antenna, and the fourth antenna other than the first antenna 21, which is detachably held, in the antenna 20. The first antenna 21 radiates radio waves when detached from the holding portion 30 and used. By doing so, power consumed by the first antenna can be saved.
Fig. 6 is a main sectional view showing an example of an external appearance of the holding portion 30 according to the present embodiment. Fig. 7 is a side sectional view showing an example of an external appearance of the holding portion 30 according to the present embodiment. The holding portion 30 includes a connecting portion 31, a hinge 32, and an attachment portion 33. The coupling portion 31 is a member that couples the holding portion 30 and the first side surface 11. The hinge 32 connects the connection portion 31 and the attachment portion 33. Also, the hinge 32 holds the mounting portion 33 at an arbitrary angle. Therefore, the holding portion 30 can direct the first antenna 21 in any direction.
The first antenna 21 is mounted on the mounting portion 33. As shown in fig. 6, the mounting portion 33 has a U-shape when viewed from the side. In this way, the operator can easily attach the first antenna 21 to the holding portion 30 by sliding it from above. Further, as shown in fig. 7, the mounting portion 33 has an L-shape that supports lower portions of both sides of the first antenna 21, respectively, when viewed from the front. That is, when the first antenna is mounted, the mounting portion 33 leaves the substantially center of the first antenna 21 empty. Therefore, the mounting portion 33 is shaped so as not to interfere with the radiation of the radio wave by the first antenna 21.
Further, as shown in fig. 6, the first antenna 21 has a grip 201. The operator detaches the first antenna 21 from the holder 30 while holding the grip 201, or aligns the first antenna 21 with the wireless tag while holding the grip 201.
Therefore, the grip 201 can improve the operability of the antenna.
Next, a hardware configuration of the wireless tag reading apparatus 1 will be described. Fig. 8 is a block diagram showing an example of the hardware configuration of the wireless tag reading apparatus 1 according to the present embodiment. The wireless tag reading apparatus 1 includes a control unit 101, a storage unit 102, a communication interface 103, an operation unit 104, a display unit 105, a mounting/demounting detection unit 106, an opening/closing drive unit 107, a first antenna 21, a second antenna 22, a third antenna 23, and a fourth antenna 24.
The control unit 101 is a computer that controls the overall operation of the wireless tag reading apparatus 1 and realizes various functions of the wireless tag reading apparatus 1. The control Unit 101 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU integrally controls the operation of the wireless tag reading apparatus 1. The ROM is a storage medium that stores various programs and data. The RAM is a storage medium that temporarily stores various programs and various data. The CPU executes programs stored in the ROM, the storage unit 102, and the like with the RAM as a work area (work area).
The storage unit 102 is a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage unit 102 stores a control program 108. The control program 108 is an operating system and a program for causing the wireless tag reading apparatus 1 to function. The control program 108 includes a program for causing the characteristic functions according to the present embodiment to function.
The communication interface 103 is an interface for communicating with other devices via a network. For example, the communication interface 103 is an interface for communicating with a server that stores information related to warehousing and warehousing.
The operation unit 104 is an input device such as a keyboard for receiving various operations.
The display unit 105 is, for example, a liquid crystal display device.
The attachment/detachment detection unit 106 (detection unit) detects that the first antenna 21 is detached from the holding unit 30. In this way, the state of the first antenna 21 can be grasped. The attachment/detachment detection unit 106 may be a mechanical switch, a photonic sensor, an infrared sensor, or a magnetic sensor. When the first antenna 21 is detached from the holding unit 30, the attachment/detachment detection unit 106 notifies the control unit 101 of the detachment via a GPIO (General purpose input/Output).
The first antenna 21, the second antenna 22, the third antenna 23, and the fourth antenna 24 are connected to the control unit 101 through coaxial cables.
The opening/closing drive unit 107 is a drive device such as a motor that opens and closes the locking unit 14.
Next, characteristic functions of the wireless tag reading apparatus 1 will be described. Here, fig. 9 is a block diagram showing an example of a characteristic functional configuration of the wireless tag reading apparatus 1 according to the present embodiment.
The control unit 101 of the wireless tag reading apparatus 1 expands the control program 108 of the storage unit 102 in the RAM and operates in accordance with the control program 108, thereby generating each functional unit shown in fig. 9 in the RAM. Specifically, the control unit 101 of the wireless tag reading apparatus 1 includes, as functional units, a reading target setting unit 1001, a notification control unit 1002, an open/close control unit 1003, and a reading control unit 1004.
The reading target setting unit 1001 sets a target to be read by the wireless tag reading apparatus 1. That is, the reading target setting unit 1001 sets predetermined article information to be read from the wireless tag by the wireless tag reading apparatus 1. The reading target may be a target object, the number of target objects, or other information.
The notification controller 1002 notifies that the reading of the wireless tag has failed when the target information set by the reading target setting unit 1001 cannot be read from the wireless tag. For example, if the article information to be read set by the reading target setting unit 1001 cannot be read from the wireless tag within a predetermined period, the notification control unit 1002 displays that the reading of the wireless tag has failed on the display unit 105. Note that the notification control unit 1002 is not limited to the display on the display unit 105, and may perform the notification by voice or other methods.
The opening/closing control unit 10003 controls the opening/closing drive unit 107 to open and close the locking unit 14. When the detachable detection unit 106 detects that the first antenna 21 has been detached from the holding unit 30, the open/close control unit 1003 controls the open/close driving unit 107 to close the entrance/exit of the tunnel 10 by the locking unit 14. That is, the locking unit 14 closes the entrance/exit of the tunnel 10 when the attachment/detachment detection unit 106 detects that the antenna 20 has been detached.
The reading control unit 1004 causes the plurality of antennas 20 to radiate radio waves. In this way, the reading control unit 1004 reads the wireless tag passing through the inside of the tunnel 10. The reading control unit 1004 sequentially radiates the radio wave from the antenna 20 in a time-sharing manner when the first antenna 21 is not detached from the holding unit 30. In this way, the read control unit 1004 reads the wireless tag.
When the attachment/detachment detection unit 106 detects that the first antenna 21 has been detached from the holding unit 30, the reading control unit 1004 causes the detached first antenna 21 to emit radio waves. Here, when the first antenna 21 has been detached from the holding portion 30, the operator reads the wireless tag by aligning the first antenna 21 with the wireless tag. Therefore, it is not necessary to radiate radio waves from the second antenna 22, the third antenna 23, and the fourth antenna 24. Therefore, when the first antenna 21 is detached from the holding unit 30, the reading control unit 1004 causes the first antenna 21, the second antenna 22, the third antenna 23, and the fourth antenna 24 to radiate radio waves.
Further, when the operator aligns the first antenna 21 with the wireless tag, the wireless tag reading apparatus 1 may erroneously read the wireless tag located outside the wireless tag reading apparatus 1. Therefore, when the locking portion 14 closes the entrance/exit of the tunnel 10, the reading control portion 1004 causes the detached first antenna 21 to radiate radio waves.
When the entrance and exit of the wireless tag reading apparatus 1 are closed by the locking portion 14, the wireless tag reading apparatus 1 does not read the wireless tag located outside the wireless tag reading apparatus 1. Therefore, when the locking portion 14 closes the entrance and exit of the tunnel 10, the reading control portion 1004 increases the output of the radio wave radiated from the first antenna 21. In this way, the read control unit 1004 improves the accuracy of reading the wireless tag.
As described above, the wireless tag reading apparatus 1 according to the present embodiment includes the tunnel 10 into which a flat car carrying an article to which a wireless tag is attached enters. A plurality of antennas 20 provided inside the tunnel 10 radiate radio waves for reading the radio tags into the tunnel 10. The antenna 20 is detachably held by the holding portion 30. That is, when the wireless tag reading apparatus 1 fails to read the wireless tag, the operator can detach the antenna 20 from the holding portion 30 and align the antenna 20 with the wireless tag that has failed to be read. Therefore, the wireless tag reading apparatus 1 can easily read a wireless tag that is difficult to read.
