Description

  The present invention relates to a long body incorporating an RFID, a method of manufacturing a long body incorporating an RFID, and a long body reader that reads information of an RFID incorporated in the long body.

  In recent years, a technique for embedding RFID (Radio Frequency Identification) in order to identify a large number of cables laid has been studied (Patent Document 1). By embedding the RFID in the cable, it is possible to accurately identify the cable using information recorded in the RFID. However, the reading range of RFID is very narrow. Therefore, the user needs to perform a reading operation while searching for an embedded position of the RFID (a position where the RFID can be read). This reading operation is a very time-consuming operation.

  In order to widen the reading range, it is conceivable to increase the transmission power of the RFID reader. However, in this method, although the reading range is widened, there is a possibility that an RFID other than the RFID of the target cable is read and misidentified.

  Thus, a technique for printing a mark on the surface of the cable sheath at a position where the RFID is embedded has been considered (Patent Document 2). By visually checking the mark, the reader can be quickly held over the position where the RFID is embedded, so that the working time can be shortened.

  Further, when reading RFID, in addition to the RFID position in the cable axis direction, the circumferential position of the cable is also important. In other words, the radio wave read by the RFID is shielded by the influence of the conductor of the cable core wire, and it may be difficult to read the RFID on the back side or side of the cable. Therefore, a technique for reading data from RFIDs embedded at all positions in the circumferential direction of the cable by arranging a large number of antennas in the circumferential direction of the cable has been considered (Patent Document 2).

  However, in the technique described in Patent Document 2, the cable surface is shaved due to the movement of the cable at the time of laying the cable, or the printed mark is faded or peeled off due to aged deterioration after laying, and the printed mark disappears. There is still a problem.

  Furthermore, when RFID read radio waves are emitted from all antennas at the same time, the radio waves interfere with each other and cannot be read. Although it is conceivable to emit radio waves at different times so that radio waves emitted from these antennas do not interfere with each other, one RFID is read by a plurality of reading operations, and the reading time becomes long. For this reason, when the cable is manufactured for the purpose of actually reading the RFID at the time of cable manufacture and checking the operation of the RFID, it is necessary to slow down the cable manufacturing speed, which increases the manufacturing cost of the cable.

  The present invention has been made in view of such a point, and a long body having a structure capable of reading information from an embedded RFID at high speed and reliably, a method for manufacturing the long body, and a long body reader are provided. The purpose is to provide.

In order to solve the above problems, the elongated body of the present invention includes a sheath formed of a material that can transmit electromagnetic waves, and an RFID embedded in the sheath. The sheath includes a first sheath on the RFID and a second sheath formed of a material having a color different from that of the first sheath. The width of the first sheath is different from the width of the second sheath. A plurality of RFIDs are embedded in the first sheath in a predetermined interval and in the axial direction, and the width of the first sheath is different between a portion where the RFID is embedded and a portion where the RFID is not embedded.
According to the above configuration, the color of the first sheath on the RFID can be made different from the color of the second sheath.

  According to the present invention, since the RFID embedded position can be visually shown, the RFID embedded position can be recognized quickly and reliably. Thereby, there is an effect that information can be read from the embedded RFID at high speed and reliably.

<First Embodiment of Long Body>
An example of the first embodiment of the present invention will be described with reference to FIGS.
[1. Structure of long body]
FIG. 1 is a transparent perspective view showing an elongated body and its internal structure according to the first embodiment of the present invention.
FIG. 2 is a cross-sectional view showing the radial internal structure of the elongated body according to the first embodiment of the present invention. An example of the long body 100 is an electric wire cable.

The long body 100 includes an RFID (Radio Frequency Identification) 1, a cable core wire 2, and a sheath 101.
The cable core wire 2 is a multi-core cable formed by covering the periphery of a bundle of four conductor wires with a cloth or the like. The RFID 1 is arranged on the surface of the cable core wire 2 at a predetermined interval in the axial direction.

  The RFID 1 includes an IC chip in which information is written and an antenna. The RFID 1 operates the IC chip by capturing radio waves with an antenna and guiding them to the IC chip. Therefore, the information written in the IC chip is read by a long body reader using electromagnetic waves via an antenna. The RFID 1 may be a material such as plastic that cannot be optically transmitted as long as it can transmit electromagnetic waves.

  There are two types of such RFIDs 1 that are recorded in a state where ID information cannot be rewritten at the time of manufacture (read only), and types that write information to an internal ROM (read / write type) when used. In this example, a read-only type will be described as an example, but a read / write type can be realized with a similar structure. The periphery of the cable core wire 2 and the RFID 1 is covered with a sheath 101.

  The sheath 101 is made of an insulating member such as polyethylene, vinyl, or rubber because it is intended to allow electromagnetic waves to pass therethrough and to protect the RFID 1 and the cable core wire 2 and to insulate them from the outside. And it is formed in the hollow substantially cylindrical shape which has an internal diameter substantially equal to the diameter of the cable core wire 2. As shown in FIG. The sheath 101 includes a first sheath 3 covering the RFID 1 and a second sheath 4 having a different color from the first sheath 3 so that the position where the RFID 1 is embedded can be recognized.

  The first sheath 3 is disposed so as to completely cover the RFID 1 (see FIG. 2). Note that the length of the shorter arc of the first sheath 3 is preferably equal to the width of the RFID 1.

  The 2nd sheath 4 is arrange | positioned so that the part which is not covered with the 1st sheath 3 in RFID1 and the cable core wire 2 may be covered completely (refer FIG. 2). Hereinafter, the color of the first sheath 3 is assumed to be A color, and the color of the second sheath 4 is assumed to be B color different from the A color.

[2. Manufacturing method of long body]
Next, the manufacturing method of the elongate body 100 which concerns on 1st embodiment is demonstrated with reference to FIG.
FIG. 3 is a block diagram showing a configuration of the long body manufacturing apparatus.
The long body manufacturing apparatus 150 is an apparatus that manufactures the long body 100, and includes a cord drum 31, an RFID insertion apparatus 33, a sheath manufacturing apparatus 36, and a winding drum 38.

  A cable core wire 2 is wound around the core drum 31. Then, the RFID insertion device 33 places the RFID 1 along the surface of the cable core wire 2 drawn from the core wire drum 31. These RFID 1 and cable core wire 2 are guided to the sheath manufacturing apparatus 36.

  The sheath manufacturing apparatus 36 generates a long body 100 by performing a process of covering the cable core wire 2 to which the RFID 1 is attached with the sheath 101. More specifically, the sheath manufacturing apparatus 36 generates the first sheath 3 with the injected A color resin 34 and generates the second sheath 4 with the injected B color resin 35 (see FIGS. 1 and 2). reference). Details of processing in the RFID insertion device 33 and the sheath manufacturing device 36 will be described later with reference to FIG.

  The winding drum 38 winds the long body 100 generated by the sheath manufacturing apparatus 36 at a predetermined speed. That is, the moving speed of the RFID 1 and the cable core 2 guided from the core drum 31 to the sheath manufacturing apparatus 36 is equal to the winding speed of the winding drum 33. In addition, the winding drum 38 including the long body 100 wound by a predetermined length is shipped as a product.

Next, processing performed by the RFID insertion device 33 and the sheath manufacturing device 36 will be described with reference to FIGS.
FIG. 4 is an explanatory view showing the structure of the RFID insertion device and the sheath manufacturing device. It is assumed that the cable core wire 2 and the long body 100 are moving at a predetermined speed in the x direction shown in FIG. 4 by winding the winding drum 38. FIG. 5 is an explanatory diagram showing the configuration of the RFID tape.

  The RFID insertion device 33 inserts the RFID tape 45 along the direction of the cable core wire 2 and inserts it into the first sheath generation container 43 of the sheath manufacturing device 36. As shown in FIG. 5, the RFID tape 45 is formed by attaching the RFID 1 to a strip-shaped tape 54. The RFID 1 is arranged at a predetermined interval in the longitudinal direction of the tape 54. The length in the longitudinal direction of the tape 534 is appropriately set according to the length of the long body 100 to be manufactured. Thereby, even when manufacturing the very long elongate body 100, RFID1 can be made to follow along the axial direction of the cable core wire 2 continuously.

  As shown in FIG. 4, the sheath manufacturing apparatus 36 includes a hollow, substantially cylindrical container, which is divided into a first sheath generation container 43 and a second sheath generation container 44. The first sheath generation container 43 is in communication with the A color resin injection port 41, and the second sheath generation container 44 is in communication with the B color resin injection port.

  A color resin 34 melted at a high pressure by an extruder or the like is injected from the A color resin injection port 41 into the first sheath generation container 43. Then, the cable core wire 2 is coated with the injected A-color resin 34 so as to cover the RFID tape 45, and the first sheath 3 is generated.

  On the other hand, the B-color resin 35 melted at a high pressure by an extruder or the like is injected into the second sheath generation container 44 from the B-color resin injection port 42. Then, the injected B-color resin 35 is coated on portions other than the first sheath 3 of the cable core wire 2 to form the second sheath 4.

  As described above, in the first embodiment of the long body described above, the color of the first sheath 3 directly above the RFID 1 can be made different from the color of the second sheath 4. Thereby, since the place where RFID1 is embedded can be shown, the position where RFID1 is embedded can be visually shown to the operator. As a result, the embedded position of the RFID 1 can be confirmed at high speed and accurately. Therefore, there is an effect that information can be read from the embedded RFID 1 at high speed and reliably.

  Moreover, in 1st embodiment of the elongate body mentioned above, the 1st and 2nd sheaths 3 and 4 have a structure which penetrated to the inside of the elongate body 100, respectively. For this reason, even if the surface of the long body 100 is shaved or the surface of the long body 100 is peeled off due to aging, the difference in color of the sheath can be determined.

<Second Embodiment of Long Body>
An example of the second embodiment of the present invention will be described with reference to FIGS. Since the structure of the elongate body 200 according to the second embodiment shown in FIGS. 6 to 9 is almost the same as that of the elongate body 100 according to the first embodiment, common portions are denoted by the same reference numerals. The description will be omitted.

[1. Structure of long body]
FIG. 6 is a transparent perspective view showing an elongated body and its internal structure according to the second embodiment of the present invention.
The long body 200 has a sheath 101 (see FIGS. 1 and 2) of the long body 100 so that the operator can visually check where the RFID 1 is embedded in the circumferential direction and the axial direction. As an alternative to this, a sheath 201 is provided. The sheath 201 is made of the same material as the sheath 101 and has the same shape. The sheath 201 includes a first sheath 61 and a second sheath 62.

  The first sheath 61 is made of the same material as the first sheath 3. In the first sheath 61, a portion 63 overlapping the RFID 1 has the same shape as the first sheath 3. On the other hand, the portion 64 not overlapping the RFID 1 is formed so as to be substantially similar to the first sheath 3, and the arc length of the portion 64 is shorter than the arc length of the portion 63. The second sheath 62 is formed in a shape that can be merged with the first sheath.

[2. Manufacturing method of long body]
Next, the manufacturing method of the elongate body 200 which concerns on 2nd embodiment is demonstrated with reference to FIG.
FIG. 7 is a block diagram illustrating a configuration of the long body manufacturing apparatus.
The long body manufacturing apparatus 250 is an apparatus that manufactures the long body 200, and has a configuration in which an RFID position detection device 71 and a stripe width controller 72 are added to the long body manufacturing apparatus 150 (see FIG. 3). .

  The RFID position detection device 71 detects the position of the RFID 1 of the RFID tape 45 inserted along the core line 2 by the RFID insertion device 33. This detection result is output to the stripe width controller 72. The means for detecting the position of the RFID 1 may be an optical sensor that detects a color difference between the RFID 1 and other parts, or whether information stored in the RFID 1 can be read. An RFID reader for determination may be used.

  The stripe width controller 72 uses the detection result input from the RFID position detection device 71 to adjust the width of the portion of the first sheath 61 (see FIG. 6) that can be seen from the appearance. The structure of the stripe width controller 72 will be described later with reference to FIG.

Next, the detailed structure of the stripe width controller 72 will be described with reference to FIG.
FIG. 8 is an explanatory diagram showing the structure of the stripe width controller. It is assumed that the long body 200 is moving at a predetermined speed in the x direction shown in FIG.

  The stripe width controller 72 is provided in the subsequent stage of the first sheath generation container 43 of the sheath manufacturing apparatus 36 and controls the amount of the A color resin output from the first sheath generation container 43 by the valve 83 to The width of the sheath 3 is adjusted. When the valve 83 is in the open position 84, the amount of A-color resin passing through the valve 83 is increased, and the wide portion 63 of the first sheath 3 is formed. On the other hand, when the valve 83 is at the throttle position 85, the A color resin passing through the valve 83 is reduced, and the narrow portion 64 of the first sheath 3 is formed. Note that the width of the second sheath 4 also changes as the width of the first sheath 3 changes.

FIG. 9 is a flowchart showing a procedure for manufacturing a long body according to the second embodiment of the present invention.
First, the RFID position detection device 71 detects whether or not the RFID 1 has passed (step S90). If it is detected that the RFID 1 has passed (YES in step S90), the stripe width controller 72 performs control for setting the valve 83 to the open position 84 after a time corresponding to the passing speed of the RFID 1 has elapsed (step S91). ). And it returns to the process of step S90 and repeats a process.

  On the other hand, if it is not detected that the RFID 1 has passed (NO in step S90), the stripe width controller 72 performs control to move the valve 83 to the aperture position 85 after a time corresponding to the passing speed of the RFID 1 has elapsed. Is performed (step S92). And it returns to the process of step S90 and repeats a process.

  In the processing of step S91 and step S92, the valve 83 is opened and closed after the time corresponding to the passing speed of the RFID 1 has elapsed because there is a distance between the RFID position detection device 71 and the valve 83. However, the moving speed of the RFID is equal to the winding speed of the winding drum 38 and is input by the user in this example, but can also be acquired by a sensor or the like. Note that the delay time may be calculated in consideration of the response time for opening and closing the valve in addition to the moving speed of the RFID 1.

  As described above, in the above-described second embodiment of the long body, the color of the first sheath 61 directly above the RFID 1 can be made different from the color of the second sheath 62. Furthermore, the width of the first sheath 61 can be made different between a place where the RFID 1 is embedded and a place where the RFID 1 is not embedded. Thereby, since the place where RFID1 is embedded can be shown, the position where RFID1 is embedded can be surely visually shown to the operator. As a result, the embedded position of the RFID 1 can be recognized more quickly and accurately. Therefore, there is an effect that the reading operation of the embedded RFID 1 can be performed quickly and easily.

  Similarly to the first embodiment of the long body, each of the first and second sheaths 61 and 62 has a structure that penetrates into the long body 200. For this reason, even if the surface of the long body 200 is shaved or the surface of the long body 200 is peeled off due to deterioration over time, the difference in color of the sheath can be determined.

  In the first and second embodiments of the long body described above, the cable core wire 2 may be a single core cable.

  Further, in the first and second embodiments of the long body described above, the A-color first sheath 21 does not reach the central portion where the RFID 1 is disposed (see FIG. 10A). Alternatively, the RFID 1 may be arranged in the first sheath 22 (see FIG. 10B).

  In the first and second embodiments of the long body described above, a pigment that can be discriminated by normal illumination may be used as a means for coloring the sheath. Alternatively, a fluorescent pigment that emits light by applying light may be used. In this way, with normal illumination, it looks like a general long body and cannot know the presence of the RFID, but the position where the RFID is embedded can be determined by applying special light. This is effective when an RFID is embedded in a place that is not normally desired to be known.

  In the first and second embodiments of the long body described above, the cable is an example of the long body, but the inside of the pipe and the like is made of the same material, such as a hollow structure or a rope. It is possible to realize a similar structure. For example, in the case of piping (pipe), if it is considered that the portion of the cable core wire is hollow, it can be realized with the same structure. A large number of pipes can be identified by RFID being embedded in the pipe.

  Further, by displaying the position of the RFID with pipe materials of different colors, it is possible to visually confirm the RFID embedding position even when the pipe surface is shaved or corroded.

  In the case of a rope, the cable core portion and the sheath portion may be made of the same material. In other words, the portion in which the RFID is embedded and the other portion of the rope before the matching are dyed with a different color pigment, and the matching may be performed. For example, it can be used for detection of a floor by identifying an elevator rope or placing an ID stored in an RFID in association with a position. Even in the case of a rope, since the rope itself is colored, it is possible to make the structure strong against color fading due to secular change.

  In the first and second embodiments of the long body described above, the material of the tape portion constituting the RFID tape may be made to be a material that is assimilated with the sheath by heat. When the tape is placed along the cable core, excessive stress is applied to the tape and RFID due to the difference in heat shrinkage between the tape and the sheath material and the difference in path length between the inside and outside when the cable is bent. May be damaged. However, when a material that dissolves and assimilates with the sheath is used for the tape, the tape disappears due to the dissolution, and the RFID can be scattered alone under the sheath. Therefore, the stress generated due to heat shrinkage or bending of the long body remains locally, and there is an effect that the damage to the RFID is reduced.

  Further, in the first and second embodiments of the long body described above, as shown in FIG. 11, a notch 55 may be made in a portion where the RFID 1 is not present on the tape 54. When an excessive stress is applied to the tape 54 by making a cut, the tape 54 is cut from 55 points of the cut and the RFID 1 is protected. Note that the same effect can be obtained by making a perforation so as to cross the position of the cut 55 instead of the cut 55.

<First Embodiment of Long Body Reading Device>
An example of the first embodiment of the long body reading device will be described with reference to FIGS. In addition, about the common part with 1st and 2nd embodiment of a elongate body, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 12 is a block diagram showing a long body manufacturing apparatus to which the long body reading apparatus according to the first embodiment of the present invention is applied.
In order to inspect whether the RFID 1 embedded in the long body 100 is operating normally, it is necessary to confirm that the RFID 1 can be read after the sheath 101 is formed. Therefore, the long body manufacturing apparatus 300 further includes a long body reading apparatus 102 between the sheath manufacturing apparatus 36 of the long body manufacturing apparatus 150 shown in FIG. The long body reading device 102 reads information (for example, ID information) stored in each RFID 1 embedded in the long body 100 before being wound on the take-up drum, and accumulates the read information in the storage device 103. I will do it. In this example, the long body reading device 102 reads information from the RFID 1 embedded in the long body 100, but it goes without saying that the information can also be read from the RFID 1 embedded in the long body 200. . The detailed configuration of the long body reader 102 will be described later with reference to FIG.

[1. Configuration of long body reader]
Next, the configuration of the long body reader 102 will be described with reference to FIG.
FIG. 13 is a block diagram showing the configuration of the long body reader according to the first embodiment of the present invention.

  The long body reading device 102 includes a control unit 110, a driving unit 111, an antenna 113, stripe detection sensors 115 and 116, a housing 119, and an RFID reading unit 120.

  The housing 119 has a hollow and substantially cylindrical shape. Since the long body 100 output from the sheath manufacturing apparatus 36 passes through the hollow portion of the housing 119, the diameter of the hollow portion is longer than the diameter of the long body 100. Stripe detection sensors 115 and 116 are provided on the inner wall of the housing 119 at a predetermined interval in the circumferential direction. An antenna 113 is provided between the stripe detection sensors 115 and 116. Therefore, when the housing 119 rotates, both the antenna 113 and the stripe detection sensors 115 and 116 rotate.

  The stripe detection sensors 115 and 116 detect changes in color and shade (boundary between the sheath 3 and the sheath 4) and output the detection results to the control unit 110. In this example, the stripe detection sensors 115 and 116 detect the A color of the first sheath 3. As the stripe detection sensors 115 and 116, for example, a photo sensor can be applied.

  The control unit 110 operates the drive unit 111 based on the detection results from the stripe detection sensors 115 and 116. As the drive unit 111 operates, the housing 119 rotates in the direction 112 or the direction 114 so that the antenna 113 is positioned directly above the first sheath 3.

  On the other hand, the antenna 113 transmits an RFID reading electromagnetic wave generated by the RFID reading unit 120. In addition, when the RFID 1 receives this electromagnetic wave, the antenna 113 receives the electromagnetic wave transmitted from the RFID 1 and outputs it to the RFID reading unit 120. Information stored in advance in the RFID 1 is placed on the electromagnetic wave transmitted from the RFID 1.

  The RFID reading unit 120 extracts information from the electromagnetic wave received by the antenna 113 and stores it in the storage device 103.

[2. Operation of long body reader]
Next, the operation of the long body reader 102 will be described with reference to FIG.
FIG. 14 is a flowchart showing the flow of the operation of the elongated body reading apparatus according to the first embodiment of the present invention.

  First, the stripe detection sensors 115 and 116 are activated (step S121). And it is confirmed whether the stripe detection sensor 115 detected A color of the 1st sheath 3 (step S122). If the stripe detection sensor 115 detects the A color (YES in step S122), the control unit 110 operates the driving unit 111 to rotate the casing 119 in the direction 114 by a predetermined distance (step S124). And it returns to the process of step 121 and repeats a process.

  On the other hand, if the stripe detection sensor 115 has not detected the A color (NO in step S122), it is confirmed whether or not the stripe detection sensor 116 has detected the A color of the first sheath 3 (step S123).

  If the stripe detection sensor 116 detects A color (YES in step S123), the control unit 110 operates the drive unit 111 to rotate the casing 119 in the direction 112 by a predetermined distance (step S125). And it returns to the process of step S121 and repeats a process.

  On the other hand, if the stripe detection sensor 116 has not detected A color (NO in step S123), the control unit 110 stops the drive unit 111 so that the housing 119 does not rotate (step S126). And it returns to the process of step S121 and repeats a process.

  As described above, in the first embodiment of the long body reading device described above, the A color of the first sheath 3 is detected by the stripe detection sensors 115 and 116. Then, based on the detection result, the housing 119 including the antenna 113 can be rotated so that the antenna 113 is positioned directly above the first sheath 3. As a result, the antenna 113 can always be disposed directly above the RFID 1. As a result, the RFID reader 120 can reliably read the information stored in the RFID 1 in the best radio wave condition.

<Second Embodiment of Long Body Reading Device>
An example of the first embodiment of the long body reader will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the common part of 1st and 2nd embodiment of a long body, and 1st embodiment of a long body reader, and description is abbreviate | omitted.

[1. Configuration of long body reader]
FIG. 15 is a block diagram showing a configuration of a long body reading apparatus according to the second embodiment of the present invention.

  The long body reading device 130 reads ID information and the like stored in each RFID 1 embedded in the long body 100 and stores the read information, similarly to the long body reading device 102 according to the first embodiment. Accumulate in device 103. The elongated body reader 130 includes an RFID reader 120, a controller 131, an antenna switching unit 132, a plurality of stripe detection sensors 133, and a plurality of antennas 134 paired with each stripe detection sensor 133. Is provided.

  The housing 119 has a hollow and substantially cylindrical shape. Since the long body 100 output from the sheath manufacturing apparatus 36 passes through the hollow portion of the housing 119, the diameter of the hollow portion is longer than the diameter of the long body 100. On the inner wall of the housing 119, a plurality of stripe detection sensors 133 and antennas 134 are provided at equal intervals in the same direction so as to surround the long body 100.

  The stripe detection sensor 133 detects a change in color or shade and outputs the detection result to the control unit 131. In this example, the stripe detection sensor 133 detects the A color of the first sheath 3.

  Based on the detection result from each stripe detection sensor 133, the control unit 110 searches which stripe detection sensor 133 has detected the A color and outputs the search result to the antenna switching unit 132.

  The antenna switching unit 132 electrically connects the antenna 134 paired with the stripe detection sensor 133 that has detected the A color to the RFID reading unit 120 based on the search result input from the control unit 131.

  The antenna 113 transmits an RFID reading electromagnetic wave generated by the RFID reading unit 120. In addition, when the RFID 1 receives this electromagnetic wave, the antenna 113 receives the electromagnetic wave transmitted from the RFID 1 and outputs it to the RFID reading unit 120.

  The RFID reading unit 120 extracts information from the electromagnetic wave received by the antenna 113 and stores it in the storage device 103.

[2. Operation of long body reader]
Next, the operation of the long body reader 130 will be described with reference to FIG.
FIG. 16 is a flowchart showing a flow of operations of the long body reading apparatus according to the second embodiment of the present invention.

  First, all the stripe detection sensors 133 are activated (step S140). Here, the control unit 110 searches which stripe detection sensor 133 has detected the A color (first sheath 3) (step S140).

  Subsequently, the control unit 110 controls the antenna switching unit 132 to select the antenna 134 that is paired with the stripe detection sensor 133 searched in the process of step S140, and the selected antenna 134 and the RFID reading unit 120 Are electrically connected (step S142).

  After the above process is completed, the RFID reader 120 reads the data stored in the RFID 1 using the antenna 134 selected in the process of step S142 and stores it in the storage device 103 (step S143). And it returns to the process of step S140 and repeats a process.

  As described above, in the second embodiment of the long body reading device described above, information is received from the RFID 1 using the antenna 134 that is paired with the stripe detection sensor 133 that detects the A color of the first sheath 3. Can be read. Thereby, the RFID reader 120 can reliably read the information stored in the RFID 1 in the best radio wave condition.

  In the second embodiment of the long body reading device, the plurality of stripe detection sensors 133 and the plurality of antennas 134 are arranged so as to surround the long body 100. Therefore, there is no need to rotate the housing 119 in accordance with the rotation of the long body, and the drive unit 111 can be eliminated to reduce the size of the apparatus.

  In the first and second embodiments of the long body reading device described above, the example is applied to the long body manufacturing apparatus. However, for example, the present invention can be applied to a wire drawing machine.

  As mentioned above, although the example of each embodiment of the present invention was explained, the present invention is not limited to the above-mentioned each embodiment, and it is not limited to the scope of the present invention described in the claims. Needless to say, modifications and application examples are included.
