[0006] The problem to be solved by the utility model

[0007] The results of the operation confirmation are printed via the needle detector's communication function or displayed on the needle detector's control panel. However, the results of the operation confirmation are only printed or displayed from the needle detector's perspective.

[0008] Methods for solving problems

[0009] One embodiment of this disclosure relates to a needle detector for detecting whether an object to be tested contains unwanted metal. The needle detector includes: a device body for mounting components constituting the needle detector; the components include: a storage device for storing detection-related information; a communication device enabling bidirectional communication between the needle detector and an external device; and a control device connected to the storage device and the communication device for controlling the communication device to send information stored in the storage device to the external device according to a request from the external device.

[0010] Based on the above configuration, by incorporating a communication device capable of two-way communication, information related to the needle detector can be provided at any time upon request from an external device. Therefore, when necessary, the required information can be provided to an external device that communicates two-way with the needle detector at any time.

[0011] In the aforementioned needle detector, the constituent components further include a metal detection device for detecting unwanted metal. The metal detection device is connected to the control device, and the control device can store operation confirmation information based on the operation confirmation performed before using the metal detection device in the storage device as the information.

[0012] Based on the above configuration, operational confirmation information can be provided at any time when necessary. Therefore, it is possible to ascertain at any time whether operational confirmation related to the needle detector's operation has been performed appropriately, when necessary. This is effective in ensuring that the needle detector's operational confirmation is performed properly.

[0013] In the aforementioned needle detector, the constituent components further include an information detection device for detecting and identifying identification information of the object to be detected. The information detection device is connected to the control device. The control device can store individual management information obtained by associating the identification information and the detection result information representing the detection result together with the operation confirmation information in a storage device as the information.

[0014] Furthermore, in the aforementioned needle detector, the control device can receive, via the communication device, the detection result of an information detection device that detects and identifies the identification information of the object to be detected, relative to the identification information separately set in the needle detector. The control device can store individual management information obtained by associating the identification information and the detection result information representing the detection result together with the operation confirmation information in the storage device as the information.

[0015] Based on the above structure, individual management information can be provided at any time when necessary. Therefore, it is possible to monitor and confirm whether the operations related to the needle detector are being performed appropriately at any time.

[0016] In the aforementioned needle detector, the control device can, based on a request received via the communication device for identification information from an external device, control the communication device to send individual management information stored in the storage device corresponding to the received identification information to the external device.

[0017] Based on the above configuration, individual management information can be provided for each item to be tested at any time when necessary. Therefore, it is possible to monitor at any time whether the needle detector is being tested under appropriate operational verification for each item. This is effective in ensuring that the needle detector testing is performed under appropriate operational verification.

[0018] In the aforementioned needle detector, the communication device can be a wireless communication device.

[0019] Based on the above configuration, the needle detector can communicate bidirectionally with external devices capable of wireless communication. Therefore, as long as the needle detector communicates with external devices capable of wireless communication, it can be ensured that the detection is performed under proper operational verification, thereby improving reliability.

[0020] In the aforementioned needle detector, the communication device can also be a wired communication device.

[0021] Based on the above configuration, the needle detector can communicate bidirectionally with external devices capable of wired communication. Therefore, as long as the needle detector communicates with an external device capable of wired communication, it can be ensured that the needle detector's detection is performed under proper operational verification, thereby improving reliability.

[0022] The aforementioned wired communication device can be implemented by having a connector section with a cable for connecting to enable bidirectional communication with external devices.

[0023] In the aforementioned needle detector, the component may include a display monitor, which is connected to the control device, and the control device may control the display monitor to display the information.

[0024] Based on the above configuration, the needle detector can display information on a monitor. Therefore, it is easy to determine whether the needle detector is performing its detection under appropriate operational confirmation.

[0025] In the aforementioned needle detector, the identification information may be an ID signal stored in an RF tag, which may be used together with the object to be detected for detection.

[0035] First Implementation Method

[0036] The first embodiment will now be described with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the needle detector 10 is a detection device used to detect whether unwanted metal is mixed into a product 11 before it is shipped as a product to be inspected. The product 11 is, for example, a sewn garment. Unwanted metal is, for example, a broken needle. In the following description, the detection of whether unwanted metal is mixed into the product 11 may be simply described as "needle detection".

[0038] Needle detector

[0039] The needle detector 10 includes a main body 20. The main body 20 is used to mount the components S constituting the needle detector 10. The components S include a conveyor belt 21, a metal detector 22, an information detection device 23, a control unit 24, and a display monitor 25.

[0040] main body of the device

[0041] The main body 20 of the device is a cuboid with a height equal to the plane of the paper. The main body 20 is movable and mounted via wheels or other means. Figure 1 On the floor of the factory or other testing space, inside the paper. In the following description, directional terms such as "up" and "down" are defined based on the direction of gravity. The direction perpendicular to the "up and down direction" of the main body 20 of the device, i.e. Figure 1 The "vertical direction" refers to the "width direction" of the main body 20 of the device. The direction perpendicular to both the "vertical direction" and the "width direction" is... Figure 1 The left and right directions in the diagram represent the "transfer direction" of product 11 during inspection. The transfer direction is... Figure 1 The direction from right to left in the middle, i.e., the forward direction, or the return direction opposite to the forward direction.

[0042] Constituent components

[0043] The conveyor belt 21 is an endless strip-shaped component with a certain thickness. The width direction of the conveyor belt 21 is consistent with the width direction of the device body 20. The conveyor belt 21 is mounted on multiple rollers installed on the device body 20. The multiple rollers are driven to rotate, for example, by a motor installed on the device body 20. The conveyor belt 21 rotates along with the rotation of the multiple rollers, thereby conveying the product 11 along the conveying direction.

[0044] The metal detector 22 is integrally assembled with the main body 20. The metal detector 22 is gate-shaped and spans the width of the conveyor belt 21. The two support pillars of the gate-shaped metal detector 22 are respectively fixed on both sides of the main body 20 in the width direction.

[0045] The metal detection device 22 internally includes a plurality of first sensors 22a. The plurality of first sensors 22a are arranged along the width direction of the conveyor belt 21 in the span across the conveyor belt 21. The device body 20 internally includes a plurality of second sensors 20a. The plurality of second sensors 20a are arranged in a straight line along the width direction of the device body 20. Each first sensor 22a is paired with one of the plurality of second sensors 20a. Each second sensor 20a is mounted on the side opposite to the metal detection device 22, relative to the conveyor belt 21.

[0046] For example, as the product 11, conveyed by conveyor belt 21, passes by, each first sensor 22a detects the distortion of the magnetic field between each paired first sensor 22a and second sensor 20a. Therefore, each first sensor 22a detects whether unwanted metal has been mixed into the product 11. For example, the sensor sensitivities of each first sensor 22a and each second sensor 20a are adjusted to detect unwanted metal without detecting necessary metal components in the product 11.

[0047] The information detection device 23 is integrally assembled with the main body 20. The information detection device 23 is located downstream of the metal detector 22 in its direction of travel. The information detection device 23 is gate-shaped and spans the width of the conveyor belt 21. The two support pillars of the gate-shaped information detection device 23 are respectively fixed to both sides of the main body 20 in the width direction.

[0048] The information detection device 23 internally includes a radio wave transmitter 23a and an information reader 23b. The radio wave transmitter 23a emits radio waves of a specific frequency. The output intensity, more specifically, the directionality of the radio wave transmitter 23a is adjusted to emit radio waves toward the product 11 passing through the information detection device 23. The information reader 23b receives and reads the ID signal transmitted by the RF tag 12 (described later) in response to the radio waves emitted by the radio wave transmitter 23a. Thus, the information detection device 23 detects the ID signal transmitted by the RF tag 12 (described later) in response to the radio waves emitted by the radio wave transmitter 23a.

[0049] The control unit 24 can be installed inside the device body 20 or located outside the device body 20. The control unit 24 is electrically connected to the metal detector 22, the information detection device 23, and the display monitor 25 via wires. The control unit 24 includes a control device 31, a storage device 32, and a communication device 33. The control device 31 is connected to the storage device 32 and the communication device 33.

[0050] The control device 31 is a processing circuit composed of a microcomputer, including a central processing unit (CPU). The control device 31 performs various processes related to the detection of product 11, such as starting and stopping the needle detector 10. The control device 31 performs these product-related processes based on signals input from the metal detector 22 and the information detection device 23. These product-related processes include: storing the detection results in the storage device 32; controlling the communication device 33 to output the detection results to the outside of the needle detector 10; and displaying the detection results on the display monitor 25.

[0051] Storage device 32 is used to store various information. Storage device 32 includes computer-readable media such as RAM (Random Access Memory) and ROM (Read-Only Memory). The various information includes information related to the detection results of product 11 and information related to the identification results of product 11. The information related to the detection results of product 11 is the detection result of metal detector 22, including detection result information and operation confirmation information. The detection result information indicates whether product 11 contains unwanted metal. Furthermore, the detection result information includes detection environment information related to the sensor sensitivity of metal detector 22, i.e., each first sensor 22a and each second sensor 20a. The operation confirmation information displays the results of the operation confirmation performed before use by needle detector 10, i.e., metal detector 22. The information related to the identification results of product 11 is the detection result of information detection device 23.

[0052] For example, the needle detector 10 requires operational verification before use. Operational verification aims to confirm whether the metal detector 22 can detect metal. Operational verification needs to be performed periodically. During operational verification, a result indicating no abnormality is obtained when metal can be detected between each paired first sensor 22a and second sensor 20a. In other words, the needle detector 10 is configured such that it can perform needle detection when operational verification is performed periodically and a result indicating no abnormality is obtained. Conversely, the needle detector 10 is configured such that it cannot perform needle detection if operational verification is not performed periodically or if an abnormal result is obtained.

[0053] The communication device 33 connects the needle detector 10 (i.e., the control device 31) to the external device 50 in a communicative manner. The external device 50 is a separate device from the needle detector 10, such as a printer, computer terminal, or server computer. The needle detector 10 and the external device 50 can communicate bidirectionally via the communication device 33. The communication device 33 has both wireless and wired communication capabilities. In other words, the communication device 33 is both a wireless communication device and a wired communication device. Based on a request received from the external device 50 via the communication device 33, the control device 31 controls the communication device 33 to send the request-related information stored in the storage device 32 to the external device 50.

[0054] For example, such as Figure 2 As shown, when the external device 50 has wireless communication capabilities, the communication device 33 enables bidirectional communication between the needle detector 10 and the external device 50 via network-based wireless communication. Upon request from the external device 50, the communication device 33 transmits information stored in the storage device 32 to the external device 50 via the network.

[0055] For example, such as Figure 3 As shown, when the external device 50 has wired communication capabilities, the communication device 33 enables bidirectional communication between the needle detector 10 and the external device 50 via a cable 60. The cable 60, for example, electrically connects the needle detector-side connector 33a of the communication device 33 to the external device-side connector 50a of the external device 50. Upon request from the external device 50, the communication device 33 transmits information stored in the storage device 32 to the external device 50 via the cable 60.

[0056] The display monitor 25 can be embedded within the device body 20 or disposed externally. The display monitor 25 can display the start and stop of the needle detector 10, as well as various information related to the detection of the product 11. The display monitor 25 may be, for example, a liquid crystal display unit.

[0057] RF tag

[0058] like Figure 4 As shown, each of the products 11 to be inspected by the needle detector 10 has an RF tag 12. For example, the RF tag 12 is directly attached to the product 11 or packaged together with the product 11. In other words, when transported by the conveyor belt 21, each product 11 is transported together with its RF tag 12.

[0059] The RF tag 12 includes an antenna and an IC chip. The antenna generates power using radio waves emitted by the radio wave transmitter 23a. The antenna type is selected based on the communication method between the information detection device 23 and the RF tag 12. For example, when the communication method is radio wave, the antenna can be a plate antenna. When the communication method is electromagnetic induction, the antenna can be a coil antenna. The IC chip uses the power generated by the antenna to output an ID signal representing the internally stored electrical information. The IC chip contains a storage circuit. The storage circuit stores electrical information related to the RF tag 12 containing the IC chip. This electrical information becomes identification information related to the identification result of the product 11 with the RF tag 12. The identification information includes product information used to identify the product 11 with the RF tag 12. Product information may include, for example, the product 11's trade name, color, size, and shipping location. Furthermore, the identification information may also include manufacturing information such as the product 11's manufacturing plant and production line, or testing information implemented during the manufacturing process.

[0060] Needle detector testing process

[0061] like Figure 1 As shown, in the needle detector 10, which can perform needle detection, the control device 31 controls the conveyor belt 21 to rotate in the forward direction. Thus, the product 11 is conveyed downstream by placing it and the RF tag 12 sequentially on the upstream side of the conveying direction.

[0062] Next, the control device 31 determines whether the product 11 contains unwanted metal based on the detection results of each of the first sensors 22a. Thus, the product 11 is inspected for metal as it is conveyed via the conveyor belt 21 and passes through the metal detector 22.

[0063] Next, when it is determined that product 11 is not mixed with unnecessary metal, the control device 31 controls the conveyor belt 21 to rotate in the same direction. Thus, when it is not determined that product 11 is mixed with unnecessary metal, after product 11 passes through the metal detector 22, it is conveyed by the conveyor belt 21 and passes through the information detection device 23, where the ID signal is read.

[0064] Next, the control device 31 identifies the product 11 based on the reading result from the information detection device 23. In this case, the control device 31 performs a process that associates the detection result (i.e., the detection result information related to the product 11) with the information related to the identification result of the product 11. The process performed by the control device 31 includes generating individual management information by associating the information related to the identification result of the product 11 and the detection result information together with operation confirmation information, and storing the individual management information obtained through this generation process in the storage device 32. The individual management information stored in the storage device 32 is sent to the external device 50 according to a request received by the communication device 33 from the external device 50.

[0065] Then, after identifying product 11, control device 31 continues to control conveyor belt 21 to rotate in the forward direction. As a result, product 11 is conveyed by conveyor belt 21 to the downstream side of the conveying direction and is removed from conveyor belt 21 together with RF tag 12. Thus, the detection of product 11 in needle detector 10 is completed.

[0066] On the other hand, when it is determined that product 11 contains unwanted metal, the control device 31 controls the conveyor belt 21 to rotate in the return direction. Therefore, when it is determined that product 11 contains unwanted metal, after passing through the metal detector 22, product 11 is no longer conveyed downstream in the conveying direction, but is returned upstream in the conveying direction along with the RF tag 12. Then, product 11 is re-inspected in the needle detector 10, etc. In this case, the control device 31 does not generate individual management information for product 11 for re-inspection, etc.

[0067] The function of this implementation method

[0068] The needle detector 10 is equipped with a communication device 33 capable of two-way communication. Therefore, information related to the detection of the needle detector 10 can be provided at any time according to the request of the external device 50.

[0069] For example, based on a request related to identification information received from external device 50 via communication device 33, control device 31 controls communication device 33 to send individual management information related to the received identification information stored in storage device 32 to external device 50. In other words, when a request related to identification information is received from external device 50 via network, communication device 33 sends individual management information to external device 50 via network-based wireless communication. When a request related to identification information is received from external device 50 via cable 60, communication device 33 sends individual management information to external device 50 via wired communication based on cable 60.

[0070] Effects of this implementation method

[0071] (1-1) When necessary, it can provide individual management information to external devices 50 that communicate bidirectionally with the needle detector 10 at any time.

[0072] (1-2) The control device 31 stores operation confirmation information, representing the result of the operation confirmation performed before the use of the metal detector 22, in the storage device 32. Therefore, operation confirmation information can be provided at any time when necessary. Thus, it is possible to know at any time whether the detection of the needle detector 10 is performed under appropriate operation confirmation. This is effective in ensuring that the detection operation confirmation of the needle detector 10 is performed properly.

[0073] (1-3) The control device 31 stores individual management information obtained by associating identification information and detection result information representing the detection result with operation confirmation information in the storage device 32. Therefore, individual management information can be provided at any time when necessary. As a result, operation confirmation related to the detection of the needle detector 10 is performed to determine whether it is appropriate.

[0074] (1-4) Based on a request related to identification information received from external device 50 via communication device 33, control device 31 controls communication device 33 to send individual management information corresponding to the received identification information to external device 50. Therefore, individual management information can be provided individually for the inspected product 11 at any time when necessary. This allows for individual monitoring of whether the inspection by the needle detector 10 is being performed under appropriate operational verification. This is effective in ensuring that the inspection by the needle detector 10 is carried out under appropriate operational verification.

[0075] (1-5) Through the communication device 33 equipped with a wireless communication device, the needle detector 10 can communicate bidirectionally with an external device 50 capable of wireless communication. Therefore, when communicating with an external device 50 capable of wireless communication, the reliability of the needle detector 10's detection under proper operational verification can be improved.

[0076] (1-6) Through the communication device 33 equipped with a wired communication device, the needle detector 10 can communicate bidirectionally with an external device 50 capable of wired communication. Therefore, when communicating with an external device 50 capable of wired communication, the reliability of the needle detector 10's detection under proper operational verification can be improved.

[0077] (1-7) The control device 31 controls the display monitor 25 to display individual management information. Therefore, the needle detector 10 can display individual management information through the display monitor 25. Thus, it is easy to determine whether the detection by the needle detector 10 is being performed under appropriate operational confirmation.

[0078] (1-8) The identification information is an ID signal stored in the RF tag 12, which is supplied for testing together with the product 11. Thus, the needle detector 10 can manage the information of the product 11 supplied for testing together with the RF tag 12. Therefore, the reliability of ensuring that the RF tag 12 is supplied for testing together with the item to be tested can be improved.

[0079] Second Implementation Method

[0080] The second embodiment will now be described with reference to the accompanying drawings. This embodiment differs from the first embodiment in the configuration of the identification information. Therefore, descriptions of configurations identical to those in the first embodiment will be omitted.

[0081] One-dimensional barcode

[0082] like Figure 5 As shown, each product 11, which is the object to be inspected by the needle detector 10, has a one-dimensional barcode 13. For example, the one-dimensional barcode 13 is printed on the product 11 itself or on the packaging of the product 11. In other words, when transported by the conveyor belt 21, each product 11 is transported together with its one-dimensional barcode 13. The one-dimensional barcode 13 serves as identification information associated with the identification result of the product 11. In this embodiment, the one-dimensional barcode 13 is an image code.

[0083] The information detection device 23 of this embodiment includes a barcode reading unit 23c. The barcode reading unit 23c reads the one-dimensional barcode 13. Thus, the information detection device 23 detects the one-dimensional barcode 13. Then, the control device 31 identifies the product 11 based on the reading result of the information detection device 23, i.e., the one-dimensional barcode 13.

[0084] Effects of the second implementation method

[0085] According to the second embodiment described above, in addition to achieving the same functions and effects as the first embodiment, the following effects can also be obtained.

[0086] (2-1) The identification information is a one-dimensional barcode 13, which is printed on the product 11 and used for inspection together with the product 11. Thus, the needle detector 10 can manage the information of the product 11 with the one-dimensional barcode 13 printed on it. Therefore, the reliability of ensuring that the product 11 with the one-dimensional barcode 13 is inspected by the needle detector 10 under proper operational verification can be improved.

[0087] Third Implementation Method

[0088] The third embodiment will now be described with reference to the accompanying drawings. This embodiment differs from the first embodiment in the configuration of the information detection device 23. Therefore, descriptions of configurations identical to those in the first embodiment will be omitted.

[0089] Information detection device

[0090] like Figure 6 As shown, in this embodiment, the information detection device 23 is used in conjunction with the needle detector 10 and is provided separately from the needle detector 10. For example, the information detection device 23 is provided separately from the device body 20. The information detection device 23 is provided downstream of the metal detector 22 in the traveling direction, such that the detection range is the area 21a. In this case, the radio wave emitting unit 23a adjusts the output intensity, more specifically the directionality, to emit radio waves toward the product 11 passing through the area 21a. According to the third embodiment, the same function and effect as the first embodiment can be obtained.

[0091] Other implementation methods

[0092] The above-described embodiments can be modified as follows. The embodiments and the following modifications can be combined and implemented within the scope of technical inconsistency.

[0093] In various embodiments, the needle detector 10 does not necessarily have to be equipped with a display monitor 25.

[0094] In various embodiments, the communication device 33 can be a wireless communication device or a wired communication device. For example, when the communication device 33 is a wireless communication device, the needle detector 10 becomes a needle detector dedicated to wireless communication. Furthermore, when the communication device 33 is a wired communication device, the needle detector 10 becomes a needle detector dedicated to wired communication.

[0095] In various embodiments, the request from external device 50 may be a request to aggregate multiple identification information. The multiple identification information may be specified individually or by date unit.

[0096] In various embodiments, in addition to controlling the communication device 33 to send individual management information, the control device 31 can also control the communication device 33 to send either detection result information or operation confirmation information.

[0097] In the second embodiment, the image code may include a two-dimensional barcode or a multidimensional barcode. In this case, the information detection device 23 only needs to be able to read the multidimensional barcode.
