Description

  The present invention relates to a technique for managing article information, and more particularly, to a technique for managing article information using an IC tag.

  In recent years, IC tags (hereinafter also simply referred to as “tags”) have been used to identify objects. This tag stores information such as its own identification information, and has a function of transmitting and receiving information to and from the management system using radio waves. This tag technology is used in every scene of the industry, for example, affixed to a product produced in a factory, and also used when managing product information in the factory.

  As a technique for managing product information, for example, after a tag reading device reads tag identification information, the tag identification information is transmitted to a computer, and inspection information (corresponding to the tag identification information from the computer) ( Technology for receiving product information (inspection items, inspection order, etc.), inspecting the product while an operator refers to the inspection information, and managing the product information is disclosed (for example, see Patent Document 1).

In addition, for example, as a result of inspection performed by an operator, information related to the result is input from a personal computer and written to the tag via a tag writing device. In the process after writing, the result of the inspection written on the tag is related. A technique for managing product information by referring to information is disclosed (for example, see Patent Document 2).
JP 2000-218472 A JP 2003-208207 A

  However, in the technique described in Patent Document 1 described above, the operator can accurately inspect the product by referring to the inspection information of the product, but the push button type switch that the operator has at hand Since the inspection result is input by selecting and pressing, there is a problem that it takes time until the operator inputs the inspection result after determining the inspection result of the product.

  In addition, in the technique described in Patent Document 2 described above, it is possible to obtain information on the result of the product inspection without referring to the personal computer by referring to the information written in the tag. There is a problem that it takes time for the worker to input the inspection result via the personal computer after the worker determines the inspection result because the worker has to input information on the inspection result from the personal computer.

  Therefore, an object of the present invention is to provide a technique capable of reducing the time for an operator to input information related to an article to be managed.

  In order to achieve the above object, the tag information reading device of the present invention has a function of reading information on a tag attached to an article to be managed and storing the read information in a storage device. This tag information reading apparatus includes a reader that is partially or wholly attached to the body and reads tag information, a first contact detection sensor and a second contact detection sensor that detect contact, and a processing unit. In addition, when both the first contact detection sensor and the second contact detection sensor are in a contact state, the processing unit reads the read information and a predetermined first value when the reader reads the information from the tag. And stored in a storage device. On the other hand, when only one of the first contact detection sensor and the second contact detection sensor is in a contact state or both are not in a contact state, the reader reads information from the tag, The predetermined second value is stored in the storage device.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to reduce the time which makes a worker input the information regarding the articles | goods to be managed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<< First Embodiment >>
First, a first embodiment of the present invention will be described.
FIG. 1 is a configuration diagram of a product information management system (tag information reading device) in the first embodiment. As shown in FIG. 1, the product information management system 10A includes a first contact detection unit (first contact detection sensor) 110, a second contact detection unit (second contact detection sensor) 120, and a processing unit. 130A, a first communication unit (first reader) 140A, a second communication unit (second reader) 150A, and a relay unit 160 are included.

  The first contact detection unit 110 is configured by a circuit including a power source such as the battery 111, a current detector 112, and the first contact unit 113, and the battery 111 has a function of supplying power to this circuit. . The current detector 112 has a function of detecting a current flowing through the circuit and outputting a signal to the processing unit 130A based on the detected current value.

  The first contact unit 113 has a function of outputting information related to whether or not it is in contact with another object to the processing unit 130A. In the present embodiment, the case where pressure-sensitive conductive rubber is used as the first contact portion 113 will be described, but other substances capable of detecting contact can also be used.

  This pressure-sensitive conductive rubber has a characteristic that the electric resistance value changes depending on the applied pressure. For example, in pressure-sensitive conductive rubber, conductive particles such as carbon and metal are dispersed almost uniformly in an insulating rubber material. When no pressure is applied to the pressure-sensitive conductive rubber, the conductive particles are in contact with each other. It shows a high electrical resistance value of about 100Ω. On the other hand, when a pressure is applied to the pressure-sensitive conductive rubber, the conductive particles begin to come into contact, a conductive path is formed in the rubber, the conductive path increases according to the pressure, and the electrical resistance value decreases to about 10Ω. That is, when a pressure is applied, the electric resistance value of the pressure-sensitive conductive rubber decreases.

  It is assumed that a voltage of 5V is generated in the first contact detection unit 110 by the power supplied from the battery 111. At that time, when the electrical resistance value of the first contact portion 113 decreases from 100Ω to 10Ω, the current value in the first contact detection portion 110 is (current value) = (voltage value) ÷ (resistance value) = 5V. ÷ Increased from 100 Ω = 0.05 mA to (current value) = (voltage value) ÷ (resistance value) = 5 V ÷ 10 Ω = 0.5 mA. The current value is detected by the current detector 112. Therefore, for example, when the detected current value is 0.2 mA or more, the current detector 112 is set to output the signal “1: contact” to the processing unit 130A. Thus, the predetermined threshold value regarding the current value is determined in advance, and the current detector 112 compares the detected current value with the threshold value. If the detected current value is equal to or greater than the threshold value, the first contact is made. It is determined that another object is in contact with unit 113, and a signal “1: with contact” is output to processing unit 130 </ b> A.

  In addition, as shown in FIG. 1, a second contact detection unit 120 that is a circuit including a power source such as a battery 121, a current detector 122, and a second contact unit 123 is configured. Since the configuration of the first contact detection unit 120 is the same as that of the first contact detection unit 110 described above, the description thereof is omitted.

  The processing unit 130A includes a contact detector 131, a logic negation circuit 132, a first communication control circuit 133A, and a second communication control circuit 134A.

  When the signal “1: contact is present” is input from both the current detector 112 and the current detector 122, the contact detector 131 outputs the signal “1: read request” to the first communication control circuit 133A (use The first communication unit (reader) is set as the first communication unit (first reader) 140A), and the first value is output to the relay unit 160. Here, as the first value, for example, “1: defective product” indicating that the product is a defective product is conceivable. In other cases, the contact detector 131 receives the signal “1: contact” when only one of the current detector 112 and the current detector 122 inputs the signal “1: contact”, or the signal “1: contact exists” from either of them. Is not input, the signal “1: read request” is output to the second communication control circuit 134A (the communication unit (reader) to be used is set to the second communication unit (second reader) 150A. ) And a second value that is a value other than the first value is output to the relay unit 160. Here, as the second value, for example, “0: non-defective product” indicating that the product is a non-defective product is conceivable. In order to realize these functions, for example, a signal output from the contact detector 131 to the first communication control circuit 133A is branched in the middle, and is also output to the second communication control circuit 134A and the relay unit 160. The signal which goes to the second communication control circuit 134A after branching may be configured to pass through the logic negation circuit 132.

  The first communication control circuit 133A has a function of controlling communication with the tag 20 by the first communication unit 140A. In this embodiment, when “1: read request” is input from the contact detector 131, the tag information is read from the tag 20 via the first communication unit 140A, and the read tag information is output to the relay unit 160. Has at least a function. The tag information will be described later.

  The second communication control circuit 134A has a function of controlling communication with the tag 20 by the second communication unit 150A. In the present embodiment, when “1: read request” is input from the logic negation circuit 132, the tag information is read from the tag 20 via the second communication unit 150A, and the read tag information is output to the relay unit 160. Has at least a function.

  The first communication unit 140 </ b> A has a function of communicating with the tag 20. In the present embodiment, at least a function of reading tag information from the tag 20 and outputting the read tag information to the first communication control circuit 133A under the control of the first communication control circuit 133A. In the present embodiment, the first communication unit 140A is used when reading tag information of the tag 20 attached to a product as an article to be managed one by one, so that the tag information is read from the tag 20. It is desirable to set the distance that can be within about 10 cm.

  The second communication unit 150 </ b> A has a function of performing communication with the tag 20. In the present embodiment, at least a function of reading tag information from the tag 20 and outputting the read tag information to the second communication control circuit 134A under the control of the second communication control circuit 134A. It is desirable that the second communication unit 150A has a wider reading range from the tag 20 and a longer reading distance than the first communication unit 140A.

  The relay unit 160 adds the first value or the second value input from the contact detector 131 to the tag information input from the first communication control circuit 133A or the second communication control circuit 134A, and stores the stored information. It has a function of creating and transmitting to the storage device 30. The storage information transmitted to the storage device 30 is stored in the storage device 30.

  The first communication unit 140A and the second communication unit 150A may have the same configuration. In that case, the first communication control circuit 133A and the second communication control circuit 134A may have the same configuration. Even in such a configuration, the first contact detection unit 110, the second contact detection unit 120, and the relay unit 160 are different from the case where the first communication unit 140A and the second communication unit 150A have different configurations. What is necessary is just to have the same function. The contact detector 131 outputs the first value to the relay unit 160 when the signal “1: contact is present” is input from both the current detector 112 and the current detector 122, and the communication control circuit The tag information read from the tag 20 may be read and output to the relay unit 160. In other cases, the contact detector 131 receives the signal “1: contact” when only one of the current detector 112 and the current detector 122 inputs the signal “1: contact”, or the signal “1: contact exists” from either of them. "Is not input, the second value other than the first value is output to the relay unit 160, and the communication control circuit reads and relays tag information from the tag 20 read via the communication unit. What is necessary is just to output to the part 160.

  In the following description, it is assumed that the worker uses the product information management system 10A when inspecting the quality of the product. The first value is “1: defective product” and the second value is “0: non-defective product”. However, the values used as the first value and the second value are not limited to this, and may be information related to other products (product information), information related to articles (article information), and the like.

  FIG. 2 is a schematic diagram illustrating a configuration example of the product information management system according to the first embodiment. In the product information management system 10A described above, the first contact unit 113, the second contact unit 123, the first communication unit 140A, and the second communication unit 150A are provided in the hands of workers. It is preferably used. This makes it possible to easily switch between the contact state and the non-contact state between the first contact unit 113 and the second contact unit 123, and the first communication unit 140A by the processing unit 130A as described above is provided. The communication with the tag 20 and the communication with the tag 20 via the second communication unit 150A can be easily switched.

The state in which the part 113 is provided on the belly part of the thumb of the glove 170 and the second contact part 123 is provided on the belly part of the middle finger of the glove 170 is shown as an example. However, FIG. 2 is the figure which looked at the glove which an operator wears on the right hand from the palm side. If the first contact portion 113 and the second contact portion 123 are provided at such a position, the worker can contact the first contact portion 113 and the second contact portion 123 with each other and not contact with each other. The state can be switched more easily. In addition, as shown in FIG. 2, if the first communication unit 140 </ b> A is provided on the abdomen of the index finger of the glove 170, the worker makes contact with the first contact unit 113 and the second contact unit 123. In this case, the processing unit 130A can easily communicate with the tag 20 via the first communication unit 140A. Further, if the second communication unit 150A is provided in the palm portion of the glove 170, the processing unit 130A can be used when the operator does not contact the first contact unit 113 and the second contact unit 123. Can easily communicate with the tag 20 via the second communication unit 150A. Further, the first communication unit 140A and the second communication unit 150A may have the same configuration. In that case, it is desirable to read the tag information of the tag 20 one by one using the first communication unit 140A.

In the example shown in FIG. 2, the glove 170 is for wearing on the right hand, but may be for wearing on the left hand. In the following description, the first contact portion 113 is provided on the belly portion of the thumb of the glove 170, the second contact portion 123 is provided on the belly portion of the middle finger of the glove 170, and the first communication portion 140A is provided on the glove 170. It is assumed that the second communication unit 150 </ b> A is provided on the palm portion of the glove 170.

  FIG. 3 is a configuration diagram of a tag in the first embodiment. As shown in FIG. 3, the tag 20 includes a storage unit 210, a processing unit 220, and a communication unit 230.

  The storage unit 210 can store tag information including identification information of the tag 20. Details of the tag information will be described later. The processing unit 220 has a function of transmitting the tag information stored in the storage unit 210 to the product information management system 10 </ b> A via the communication unit 230 when a tag information reading request is input from the communication unit 230. The communication unit 230 approaches a distance that allows communication with the first communication unit 140A (see FIG. 1) or the second communication unit 150A (see FIG. 1) of the product information management system 10A, and the first communication unit 140A (see FIG. 1). 1) or when receiving a radio wave transmitted from the second communication unit 150A (see FIG. 1), a function of issuing a tag information reading request to the processing unit 220 and transmitting the tag information input from the processing unit 220 to the outside. Have Here, the tag information transmitted from the communication unit 230 is input to the first communication unit 140A (see FIG. 1) or the second communication unit 150A (see FIG. 1) of the product information management system 10A.

  FIG. 4 is a configuration diagram of the storage device according to the first embodiment. As illustrated in FIG. 4, the storage device 30 includes a storage unit 310.

  The storage unit 310 can store the storage information transmitted from the relay unit 160 of the product information management system 10A as product management information (article management information). Product management information will be described later.

  FIG. 5 is a diagram illustrating a configuration of tag information in the first embodiment. As shown in FIG. 5, the tag information 211A includes tag identification information 211a assigned to uniquely identify the tag 20 (see FIG. 3). In addition, the configuration includes a product code 211b for uniquely identifying the product, a product name 211c that is the name of the product, a product factory 211d that the product is manufactured, a manufacturing date 211e that is the date that the product is manufactured, and the like. Also good.

  FIG. 6 is a diagram illustrating a configuration of product management information in the first embodiment. As shown in FIG. 6, the product management information 311 includes tag identification information 311a and product information 311f that is information about the product. Similarly to the tag information 211A, a configuration including a product code 311b, a product name 311c, a product factory 311d, a manufacturing date 311e, and the like may be used.

  FIG. 7 is a schematic diagram illustrating an example of use of the product information management system in the first embodiment. FIG. 7A illustrates a case in which tag information is read via the second communication unit in FIG. b) shows a case where tag information is read via the first communication unit. Here, referring to FIG. 7, a case where an operator manages information about product quality (“0: non-defective product” or “1: defective product”) as product information using the product information management system. (Refer to FIGS. 1 to 6 as appropriate).

  As shown in FIG. 7A, a situation is assumed in which the non-defective product 80 a, the defective product 80 b and the non-defective product 80 c placed on the belt conveyor 90 pass in front of the worker 70 in order. At this time, the worker 70 wearing the gloves 170 inspects the quality of the non-defective product 80a, the defective product 80b, and the good product 80c by visual inspection, for example. For example, after inspecting the non-defective product 80a, the worker 70 holds the hand wearing the glove 170 over the tag 20a attached to the non-defective product 80a. In this way, since the first contact part 113 and the second contact part 123 are not in contact, the product information management system 10A receives the tag information from the tag 20a via the second communication part 150A. The read tag information and product information “0: non-defective product” can be transmitted to the storage device 30 via the relay unit 160. Further, since the second communication unit 150A can read the tag identification information from the tag 20a over a wider range and a longer distance than the first communication unit 140A, the worker 70 is slightly separated from the non-defective product 80a. The tag identification information can be read from the tag 20a even if the hand is held over the place.

  Subsequently, as shown in FIG. 7B, the worker 70, for example, inspects the defective product 80b, contacts the thumb and middle finger of the hand wearing the gloves 170, and attaches the index finger to the defective product 80b. It is brought close to the tag 20b. In this way, since the first contact part 113 and the second contact part 123 are in contact, the product information management system 10A receives the tag information from the tag 20b via the first communication part 140A. The read tag information and product information “1: defective product” can be transmitted to the storage device 30 via the relay unit 160.

  Thereafter, the worker 70 inspects the non-defective product 80c. In this case as well, as in the case of inspecting the non-defective product 80a, the worker 70 holds the hand wearing the glove 170 over the tag 20c attached to the non-defective product 80c. As a result, the product information management system 10A reads the tag information from the tag 20c via the second communication unit 150A, and stores the read tag information and product information “0: non-defective product” via the relay unit 160. Can be transmitted to the device 30.

  As described above, the first communication unit 140A and the second communication unit 150A are used, and the second communication unit 150A has a wider reading range from the tag 20 and a reading distance than the first communication unit 140A. If it is set long, the worker 70 holds the hand wearing the glove 170 at a position slightly away from the tag attached to the non-defective product while the inspection result of the product is non-defective. The tag information can be read, and the read tag information and product information “0: non-defective product” can be transmitted to the storage device 30 via the relay unit 160. When the worker 70 finds a defective product 80b from the product, the operator 70 reads the tag information from the tag by bringing the index finger of the hand wearing the glove 170 close to the tag attached to the defective product, The read tag information and product information “1: defective product” can be transmitted to the storage device 30 via the relay unit 160.

  Further, a lamp is provided on the wrist or the like of the glove 170, and the processing unit 130A, if the first communication control circuit 133A communicates with the tag 20 via the first communication unit 140A, informs the fact of the lamp. You may notify the worker 70 by lighting. In this way, the worker 70 can inspect the product while confirming communication with the tag 20 via the first communication unit 140A instead of the second communication unit 150A.

  FIG. 8 is a flowchart illustrating a process flow of the product information management system according to the first embodiment. The process flow of the product information management system will be described with reference to FIG. 8 (see FIGS. 1, 5 and 6 as appropriate).

  First, it is determined whether or not the contact detector 131 has detected contact of the contact portion (step S110). That is, the contact detector 131 determines whether or not there is contact in both the first contact portion 113 and the second contact portion 123 based on signals output from the current detector 112 and the current detector 122. . When the contact is detected (“Yes” in step S110), the first communication control circuit 133A reads the tag information 211A from the tag 20 via the first communication unit 140A (step S120), and the processing unit 130A detects the tag. Product information “1: defective product” is added to the information 211A to create storage information (step S121), and the process proceeds to step S140.

  On the other hand, if no contact is detected (“No” in step S110), the second communication control circuit 134A reads the tag information 211A from the tag 20 via the second communication unit 150A (step S130). The processing unit 130A adds the product information “0: non-defective product” to the tag information 211A to create storage information (step S131), and proceeds to step S140.

  Subsequently, the processing unit 130A outputs the stored information to the relay unit 160 (step S140). Then, the relay unit 160 transmits the stored information to the storage device 30 (step S150A). The storage information transmitted to the storage device 30 is stored in the storage unit 310 (see FIG. 4) of the storage device 30 as data of the product management information 311.

  According to the first embodiment described above, the worker 70 can input the first value when the first contact portion 113 and the second contact portion 123 are in contact with each other. When the first contact portion 113 and the second contact portion 123 are not in contact with each other, the second value can be input. That is, since the worker 70 can easily switch the input value, the product information management system 10A can reduce the time for the worker 70 to input information about the product. In particular, as described above, it is suitable for a case where products carried one after another by a belt conveyor or the like are inspected, and the worker 70 needs to promptly input the inspection results. The worker 70 can perform work while referring to the product information stored in the storage device 30. For example, in the process after the product inspection, it is possible to perform work by removing defective products.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described. The second embodiment differs from the first embodiment in that the relay unit of the product information management system transmits storage information in which product information is added to tag information to the management device. Therefore, the same components or processes as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 9 is a configuration diagram of a management device according to the second embodiment. As shown in FIG. 9, the management device 40 includes a storage unit 410, a processing unit 420, and a communication unit 430.

  The storage unit 410 can store product management information 311 (see FIG. 6). Further, when storage information is input from the communication unit 430, the processing unit 420 determines whether or not to store the storage information in the storage unit 410, and stores the storage information determined to be stored as product management information 311 (see FIG. 6). ) In the storage unit 410. The communication unit 430 has a function of receiving the storage information transmitted from the relay unit 160 of the product information management system 10A and outputting it to the processing unit 420.

  FIG. 10 is a flowchart illustrating a process flow of the product information management system according to the second embodiment. With reference to FIG. 10 (refer to FIG. 1 and FIG. 9 as appropriate), the process flow of the product information management system will be described.

  As shown in FIG. 10, each process from step S110 to step S140 is the same as each process from step S110 to step S140 described in FIG. After step S140, in product information management system 10A, relay unit 160 transmits the stored information to management device 40 (step S150B). The management device 40 receives the storage information transmitted from the relay unit 160.

  FIG. 11 is a flowchart illustrating a processing flow of the management apparatus according to the second embodiment. With reference to FIG. 11 (refer to FIG. 1, FIG. 6, and FIG. 9 as appropriate), the processing flow of the management apparatus will be described. When the worker 70 determines that the product is defective as a result of the product inspection, the relay unit 160 reads the tag information 211A and the product information “1: defective product” read via the first communication unit 140A. May be transmitted to the management apparatus 40 as storage information, and the management apparatus 40 may unconditionally register the storage information in the product management information 311 of the storage unit 410.

  However, since the second communication unit 150A can read the tag information 211A from the tag 20 over a wider range and longer distance than the first communication unit 140A, the tag information 211A is read via the first communication unit 140A. After the tag information 211A and product information “1: defective product” are stored in the product management information 311, the tag information 211A and the product information read via the second communication unit 150A without the intention of the worker 70 are stored. There is a possibility that “0: non-defective product” is stored in the same product management information 311. That is, “1: defective product” registered in the product information 311f of the product management information 311 is updated to “0: non-defective product” different from the inspection result of the worker 70 (overwritten with “0: non-defective product”). there is a possibility. Here, the process for preventing the overwriting will be described with reference to FIG.

  The processing unit 420 determines whether storage information has been received via the communication unit 430 (step S210). If not received (“No” in step S210), the process returns to step S210. If received (“Yes” in step S210), data having tag identification information that matches the tag identification information of the received stored information is acquired from the product management information 311 (step S220). The processing unit 420 determines whether or not the acquisition is successful (step S230). If the acquisition fails (“No” in step S230), the received storage information is registered (added) to the product management information 311. (Step S260) The process is terminated.

  If the acquisition is successful (“Yes” in step S230), the processing unit 420 determines whether the acquired product information is “1: defective product” (step S240). If the acquired product information is “1: defective product” (“Yes” in step S240), the process ends. If the acquired product information is not “1: defective product” (“No” in step S240), the product management information 311 is updated with the received storage information (step S250), and the process is terminated.

  According to the second embodiment described above, as in the case of the first embodiment, the product information management system 10A can reduce the time for the worker 70 to input information related to the product.
