Description

  The present invention relates to an RF-ID media inspection apparatus that inspects an RF-ID media capable of writing and reading information in a non-contact state.

  In recent years, with the progress of the information-oriented society, information is recorded on a card, and information management and settlement using the card are performed. Information is recorded on a label or tag attached to a product or the like, and the product or the like is managed using the label or tag.

  In such RF-ID media, in information management using such cards, labels, or tags as products, information is written to and read from the cards, labels, or tags in a non-contact state. RF-ID media such as non-contact type IC cards, non-contact type IC labels, or non-contact type IC tags on which ICs that can be mounted are rapidly spreading due to their excellent convenience. Inspection / non-defective products are inspected by writing and reading information for inspection by a reader / writer serving as inspection means before shipment. In such a non-defective / defective product inspection, a plurality of RF-ID media are continuously conveyed, and a plurality of RF-ID media are inspected one by one by a reader / writer ( For example, see Patent Document 1.) Various means can be considered as a means for continuously conveying a plurality of RF-ID media. In the case of an individualized RF-ID medium, a plurality of RF-ID media are arranged on a conveyor belt at regular intervals. It can be considered to be carried on board. Then, the above-described inspection is performed on the RF-ID media on the transport path of the RF-ID media by the transport belt.

JP 2007-25762 A

  The RF-ID media as described above are those in which information is written or read when the antenna resonates with a radio wave having a frequency such as a UHF band or a microwave band from a reader / writer. Is designed according to the frequency at which it resonates with the radio wave from the reader / writer.

  However, when the inspection is performed in a state where the RF-ID media is mounted on the transport belt and transported as described above, if the transport belt is made of a dielectric, the frequency of the antenna of the RF-ID media is determined. The characteristic shifts in the low frequency direction. Therefore, the resonance point of the antenna deviates from the frequency used for writing and reading information for inspection with respect to the RF-ID media in the reader / writer that performs the inspection, and the RF-ID media is actually a good product. In spite of the fact that information cannot be written and read at a predetermined distance, it is determined as a defective product, or the RF-ID media is actually a defective product at a predetermined distance. There is a problem that information can be written and read, and the product is determined to be a non-defective product, and accurate inspection cannot be performed.

  The present invention has been made in view of the problems of the conventional techniques as described above, and is used for carrying and inspecting by carrying RF-ID media on the carrying surface of the carrying means. An object of the present invention is to provide an RF-ID media inspection apparatus capable of accurately inspecting an RF-ID media even if the surface is made of a dielectric.

In order to achieve the above object, the present invention provides:
An RF-ID media inspection apparatus for inspecting RF-ID media,
A conveying means for carrying the RF-ID media, and carrying means for carrying the RF-ID media on the conveying surface;
A communication antenna is provided in parallel with the RF-ID media transported by the transport means, and is transported by the transport means on the transport path of the RF-ID media in the transport means. Inspection means for performing inspection by performing non-contact communication with the RF-ID medium using the communication antenna in an inspection area facing the RF-ID medium;
When the RF-ID medium is transported to the inspection area, the RF-ID medium is separated from the transport means and floated from the transport surface.

  In the present invention configured as described above, the RF-ID medium is mounted on the transport surface of the transport means and transported. Then, non-contact communication is performed with respect to the RF-ID medium by the inspection unit on the conveyance path in the conveyance unit, so that the inspection of the RF-ID medium is performed. Here, since the RF-ID medium to be inspected is in a state of being mounted and transported on the transport surface of the transport means, if the transport surface is made of a dielectric, the RF- The resonance point of the antenna of the ID medium is shifted with respect to the frequency for performing non-contact communication by the inspection means, and an accurate inspection cannot be performed. Therefore, the RF-ID media is floated from the transport surface by the levitation means, and the inspection means inspects the RF-ID media in that state, so that even if the transport surface is made of a dielectric, it is affected by the transport surface. Therefore, the RF-ID media can be accurately inspected.

  In addition, the RF-ID medium is held in parallel with the communication antenna of the inspection unit by contacting at least the opposite ends of the upper surface of the RF-ID medium lifted from the transport surface by the floating unit. If the holding means is provided, the RF-ID medium is held in a state parallel to the communication antenna of the inspection means without depending on the force by which the RF-ID medium is floated by the levitation means. Fine control of the force to lift the RF-ID media is not necessary.

  As described above, in the present invention, when the inspection is performed by performing non-contact communication by the inspection unit with respect to the RF-ID medium that is mounted on the conveyance surface of the conveyance unit and is conveyed, -Since the ID media is configured to float from the transport surface of the transport means, the RF-ID media is in a state of being lifted from the transport surface of the transport means when being inspected. When carrying out inspection by mounting the RF-ID medium on the RF-ID medium, it is possible to accurately inspect the RF-ID medium even if the conveyance surface is made of a dielectric.

  In addition, the RF-ID medium is held in parallel with the communication antenna of the inspection unit by contacting at least the opposite ends of the upper surface of the RF-ID medium lifted from the transport surface by the floating unit. In the case having the holding means, the RF-ID medium is held in parallel with the communication antenna of the inspection means, regardless of the force by which the RF-ID medium is floated by the floating means. In this case, the RF-ID medium can be held in parallel with the communication antenna of the inspection means without performing fine control on the force to lift the RF-ID medium, and an accurate inspection can be performed.

This current is supplied to the IC chip 3, whereby information is written from the reader / writer to the IC chip 3 in a non-contact state, or information written in the IC chip 3 is read / written via the antenna unit 2. Or read by a writer. Therefore, the size of the antenna patterns 2a and 2b is designed according to the frequency at which the inlet 5 is resonated with the radio wave from the reader / writer in a state where the inlet 5 is sandwiched between the card bases 6a and 6b.

(First embodiment)
2A and 2B are diagrams showing a first embodiment of the RF-ID media inspection apparatus according to the present invention. FIG. 2A is a side view, and FIG. 2B is a reader from the configuration shown in FIG. FIG. 5 is a view of the configuration from which the writer 20 is removed as viewed from above.

  In this embodiment, the non-contact type IC card 1 shown in FIG. 1 is inspected. As shown in FIG. 2, the two conveyor belts 10a and 10b serving as the conveying means and the reader / The writer 20 is composed of two air sprayers 30 and 31, and two side plates 40a and 40b.

  The two conveyor belts 10a and 10b are made of resin and are arranged to be parallel to each other with a predetermined interval. The belt surface is used as a conveyance surface on which the non-contact type IC card 1 to be inspected is mounted, and the non-contact type IC card 1 is mounted and conveyed on the belt surface. On the belt surface, a claw 11 is provided in the area where the non-contact type IC card 1 is mounted before and after the non-contact type IC card 1 is transported, and the non-contact type IC card 1 is sandwiched by the claw 11. The region is mounted across the two conveyor belts 10a and 10b. In addition, the width of each of the conveyor belts 10a and 10b and the distance between them are the same as the width of the non-contact type IC card 1 when the two conveyor belts 10a and 10b are arranged at a predetermined interval. It has become something narrower than.

  The reader / writer 20 includes a communication antenna (not shown), and is provided to face the conveyor belts 10a and 10b above the conveyance path of the non-contact type IC card 1 by the conveyor belts 10a and 10b. The noncontact IC card 1 conveyed by the conveyor belts 10a and 10b is written in and read out from the noncontact IC card 1 by using a communication antenna to perform inspection information for noncontact communication. Perform an inspection. Note that the reader / writer 20 can write and read information to and from the non-contact type IC card 1 using the communication antenna when the non-contact type IC card 1 comes close. When the non-contact type IC card 1 is inspected using the reader / writer 20, the non-contact type communication antenna is conveyed by the conveyor belts 10a and 10b in order to accurately recognize the communication distance. Arranged in parallel to the IC card 1.

  The air sprayer 30 is a floating means of the present invention, and is disposed between the two conveyor belts 10a and 10b below the conveyor belts 10a and 10b so as to face the reader / writer 20. Yes. Then, air is blown from below onto the non-contact type IC card 1 that is mounted on the transport belts 10a and 10b and transported.

  The air spray device 31 is arranged below the transport belts 10a and 10b so as to be aligned with the air spray device 30 via the transport belt 10b. That is, the air spraying part 31 is arrange | positioned on the outer side of the conveyance belt 10b. Then, air is blown from below onto the non-contact type IC card 1 that is mounted on the transport belts 10a and 10b and transported.

  The side plates 40a and 40b are formed on the non-contact type IC card 1 by the transport belts 10a and 10b in the region where the reader / writer 20 inspects the non-contact type IC card 1 transported by the transport belts 10a and 10b. It is arranged along both sides of the transport path, and two height regulating plates 41 serving as parallel holding means are attached to the upper end portion. The height regulation plate 41 is non-contact that has been conveyed to the area to be inspected about 20 mm above the belt surface of the conveyance belts 10a and 10b, that is, the conveyance surface on which the non-contact type IC card 1 is mounted. When the type IC card 1 is lifted upward from the transport belts 10a and 10b, it abuts on the four corners which are the end portions thereof, thereby restricting the non-contact type IC card 1 to float further upward. That is, the four height regulating plates 41 have the same height with respect to the conveyor belts 10a and 10b.

  Hereinafter, the operation of the RF-ID media inspection apparatus configured as described above will be described.

  FIG. 3 is a diagram for explaining the operation of the RF-ID media inspection apparatus shown in FIG. 2. FIG. 3A is a non-contact type IC in a state where the non-contact type IC card 1 is not transported to the inspection area. The figure seen from the conveyance direction upstream of the card | curd 1, (b) The figure seen from the conveyance direction upstream of the non-contact type IC card 1 in the state with which the non-contact type IC card 1 was conveyed to the test | inspection area | region, (c). These are the figures seen from the upper side in the state shown in (b).

  As shown in FIG. 3A, the non-contact type IC card 1 to be inspected is mounted and transported on the surface of the belt so as to straddle the two transport belts 10a and 10b. The conveyor belts 10a and 10b perform an intermittent operation, thereby intermittently conveying the non-contact type IC card 1. In addition, the width of each of the conveyor belts 10a and 10b and the distance between the conveyor belts 10a and 10b are the same as the width of the non-contact type IC card 1 when the two conveyor belts 10a and 10b are arranged at a predetermined interval. By becoming narrower than that, the non-contact type IC card 1 protrudes from both sides of the conveyor belts 10a and 10b.

  When the non-contact type IC card 1 is transported by the transport belts 10a and 10b to an area facing the reader / writer 20 serving as an inspection area, air is blown upward from the air sprayer 30. The air sprayer 30 is disposed below the transport belts 10a and 10b and between the two transport belts 10a and 10b. The non-contact type IC card 1 is located in a region facing the air sprayer 30. Since it has been transported, air is blown from the transport surface side of the transport belts 10a and 10b to the non-contact type IC card 1 transported to the inspection area, and as shown in FIG. The non-contact type IC card 1 is lifted from the conveyor belts 10a and 10b. As shown in FIG. 3C, the non-contact type IC card 1 lifted from the conveyor belts 10a and 10b comes into contact with the height regulation plates 41 of the side plates 40a and 40b, and further upwards. Floating is regulated. At this time, since the heights of the four height regulation plates 41 with respect to the conveyor belts 10a and 10b are equal to each other, the four corners of the non-contact type IC card 1 are in contact with the four height regulation plates 41, respectively. In the state, the inclination of the non-contact type IC card 1 with respect to the state of being mounted on the transport belts 10a and 10b and being transported does not change, so that the communication antenna of the reader / writer 20 can be used. It becomes a parallel state.

  In this state, the reader / writer 20 writes and reads information for inspection with respect to the non-contact type IC card 1. At this time, the non-contact type IC card 1 is in a state of being lifted by about 20 mm from the conveyor belts 10a and 10b, so that the upper and lower surfaces of the non-contact type IC card 1 are not in contact with each other. Even if the belt surfaces of the conveyor belts 10a and 10b are made of a dielectric, the resonance frequency is not shifted by the dielectric, and the reader / writer 20 accurately inspects the non-contact type IC card 1. Can do.

  If the strength of the air blown from the air blower 30 is controlled so that the non-contact type IC card 1 is parallel to the communication antenna of the reader / writer 20, the height regulating plate 41 is unnecessary. However, by providing the height restricting plate 41, the air blowing strength from the air blowing device 30 is set so that the non-contact type IC card 1 comes into contact with the height restricting plate 41, and the reader / The non-contact type IC card 1 can be made parallel to the communication antenna of the writer 20.

  Further, as described above, the four height regulating plates 41 are provided so as to come into contact with the four corners of the non-contact type IC card 1, but the conveying belts 10a and 10b are driven by the air blown from the air blowing device 30. The contactless IC card 1 is placed in a state parallel to the communication antenna of the reader / writer 20 as long as it is in contact with at least the opposite ends of the upper surface of the contactless IC card 1 that is lifted from can do.

  Hereinafter, an operation when the non-contact type IC card 1 determined as a defective product as a result of the inspection as described above is discharged will be described.

  FIG. 4 is a diagram for explaining the operation when the non-contact type IC card 1 determined to be defective in the RF-ID media inspection apparatus shown in FIG. The state viewed from the upstream side in the transport direction is shown.

  As shown in FIG. 4A, after the inspection is performed in a state where the non-contact type IC card 1 is lifted from the conveyor belts 10a and 10b by the air blown from the air spraying device 30, FIG. As shown in FIG. 4C, when the air blowing from the air sprayer 30 is stopped and the non-contact type IC card 1 is determined to be defective, the air sprayer 31 Air is blown upward.

  Then, while the non-contact type IC card 1 is lowered by gravity, the air spray device 31 is disposed outside the transport belt 10b, and therefore, as shown in FIG. The end portion of the IC card 1 arranged outside the transport belt 10b is lifted upward by the air blown from the air sprayer 31.

  As shown in FIG. 4D, the non-contact type IC card 1 with the end portion arranged outside the conveyor belt 10b is lifted below the conveyor belts 10a and 10b by gravity from the outside of the conveyor belt 10a. It will fall to.

  In this way, the non-contact type IC card 1 determined as a defective product in the inspection by the reader / writer 20 falls below the conveyor belts 10a and 10b, and the non-contact type IC card 1 determined as a good product. Are mounted again on the conveyor belts 10a and 10b and conveyed.

(Second Embodiment)
FIGS. 5A and 5B are diagrams showing a second embodiment of the RF-ID media inspection apparatus of the present invention, where FIG. 5A is a side view, and FIG. 5B is a reader from the configuration shown in FIG. FIG. 5 is a view of the configuration from which the writer 20 is removed as viewed from above.

  As shown in FIG. 5, this embodiment differs from that shown in the first embodiment only in that vertical mechanisms 130 and 131 are provided instead of the air sprayers 30 and 31. .

  Hereinafter, the operation of the RF-ID media inspection apparatus configured as described above will be described.

  FIG. 6 is a diagram for explaining the operation of the RF-ID media inspection apparatus shown in FIG. 5. FIG. 6A is a non-contact type IC in a state where the non-contact type IC card 1 is not transported to the inspection area. The figure seen from the conveyance direction upstream of the card 1, (b) is the figure seen from the conveyance direction upstream of the non-contact type IC card 1 in the state where the non-contact type IC card 1 is conveyed to the inspection area, (c). These are the figures seen from the upper side in the state shown in (b).

  As shown in FIG. 6A, the non-contact type IC card 1 to be inspected is mounted and transported on the surface of the belt so as to straddle the two transport belts 10a and 10b. The conveyor belts 10a and 10b perform an intermittent operation, thereby intermittently conveying the non-contact type IC card 1. In addition, the width of each of the conveyor belts 10a and 10b and the distance between the conveyor belts 10a and 10b are the same as the width of the non-contact type IC card 1 when the two conveyor belts 10a and 10b are arranged at a predetermined interval. By becoming narrower than that, the non-contact type IC card 1 protrudes from both sides of the conveyor belts 10a and 10b.

  When the non-contact type IC card 1 is transported by the transport belts 10a and 10b to a region facing the reader / writer 20 as an inspection region, the piston 130a in the cylinder of the vertical mechanism 130 extends upward. The vertical mechanism 130 is disposed between the two conveyor belts 10a and 10b below the conveyor belts 10a and 10b, and the non-contact type IC card 1 is conveyed to a region facing the vertical mechanism 130. Therefore, the piston 130a extending upward comes into contact with the central portion of the non-contact type IC card 1, so that the non-contact type IC card 1 is transported by the conveyor belts 10a and 10b as shown in FIG. 6 (b). Will float from. At this time, since the tip of the piston 130a has an adsorbing function, the non-contact type IC card 1 that is in contact with the tip of the piston 130a is in a non-contact state with its central portion adsorbed on the tip of the piston 130a. The mold IC card 1 floats from the conveyor belts 10a and 10b. As shown in FIG. 6 (c), the non-contact type IC card 1 floating from the conveyor belts 10a and 10b has its four corners in contact with the height regulation plates 41 of the side plates 40a and 40b, and further upward. Floating is regulated. At this time, since the heights of the four height regulation plates 41 with respect to the conveyor belts 10a and 10b are equal to each other, the four corners of the non-contact type IC card 1 are in contact with the four height regulation plates 41, respectively. In the state, the inclination of the non-contact type IC card 1 with respect to the state of being mounted on the transport belts 10a and 10b and being transported does not change, so that the communication antenna of the reader / writer 20 can be used. It becomes a parallel state.

  In this state, the reader / writer 20 writes and reads information for inspection with respect to the non-contact type IC card 1. At this time, since the non-contact type IC card 1 is in a state of being lifted by about 20 mm from the conveyor belts 10a and 10b, even if the belt surfaces of the conveyor belts 10a and 10b are made of a dielectric, this dielectric Thus, the resonance frequency is not shifted, and the reader / writer 20 can accurately inspect the non-contact type IC card 1. Further, in the non-contact type IC card 1 configured as shown in FIG. 1, in the state where the object is in contact with the central portion, compared to the state where the object is in contact with the ends of the antenna patterns 2a and 2b, There is little shift in the resonance frequency described above. Therefore, the influence of the piston 130a extending from the cylinder of the vertical mechanism 130 coming into contact with the non-contact type IC card 1 is reduced. The piston 130a is preferably made of a material that does not affect the frequency characteristics, such as foamed polystyrene or foamed urethane.

  If the length of the piston 130a extending from the vertical mechanism 130 is controlled so that the non-contact type IC card 1 is parallel to the communication antenna of the reader / writer 20, the height regulating plate 41 becomes unnecessary. However, by providing the height restricting plate 41, the length of the piston 130a extending from the vertical mechanism 130 is set so that the non-contact type IC card 1 contacts the height restricting plate 41. The non-contact type IC card 1 can be made parallel to the 20 communication antennas.

  Hereinafter, an operation when the non-contact type IC card 1 determined as a defective product as a result of the inspection as described above is discharged will be described.

  FIG. 7 is a diagram for explaining the operation when the non-contact type IC card 1 determined to be defective in the RF-ID media inspection apparatus shown in FIG. The state viewed from the upstream side in the transport direction is shown.

  As shown in FIG. 7A, after the inspection is performed in a state where the non-contact type IC card 1 is lifted from the conveyor belts 10a and 10b by being pushed up by the piston 130a extending from the cylinder of the vertical mechanism 130, As shown in FIG. 4B, when the piston 130a extending from the cylinder of the vertical mechanism 130 is housed in the cylinder and the non-contact IC card 1 is determined to be defective, the vertical mechanism The piston 131a extends upward from the cylinder 131. At this time, the suction of the non-contact type IC card 1 by the piston 130a is also stopped.

  Then, since the vertical mechanism 131 is disposed outside the conveyor belt 10b while the non-contact type IC card 1 is lowered by gravity, as shown in FIG. 4C, the non-contact type IC card 1 is arranged. An end portion of the card 1 arranged outside the transport belt 10b is brought into contact with a piston 131a extending from the cylinder of the vertical mechanism 131 and lifted upward.

  As shown in FIG. 4D, the non-contact type IC card 1 with the end portion arranged outside the conveyor belt 10b is lifted below the conveyor belts 10a and 10b by gravity from the outside of the conveyor belt 10a. It will fall to.

  In this way, the non-contact type IC card 1 determined as a defective product in the inspection by the reader / writer 20 falls below the conveyor belts 10a and 10b, and the non-contact type IC card 1 determined as a good product. Are mounted again on the conveyor belts 10a and 10b and conveyed.

  In this embodiment, since the tip of the piston 130a has an adsorption function, the non-contact type IC card 1 that is in contact with the tip of the piston 130a is adsorbed at the center of the tip of the piston 130a. In the state, the non-contact type IC card 1 is described as an example in which the non-contact type IC card 1 floats from the conveyor belts 10a and 10b. However, the tip of the piston 130a may not have an adsorption function.

  In the two embodiments described above, in order to detect the non-contact type IC card 1 falling between the transport belt 10a and the side plate 40a from the outside of the transport belt 10a and below the transport belts 10a and 10b. If the non-contact type IC card 1 is determined to be defective in the inspection by the reader / writer 20, and the air sprayer 31 or the vertical mechanism 131 is driven, the sensor or valve is not used. If the contact IC card 1 is not detected, it is conceivable to stop the conveyance by the conveyance belts 10a and 10b.

  Also, as shown in the first embodiment, air is blown onto the non-contact type IC card 1 by the air sprayers 30 and 31, and the vertical mechanisms 130 and 131 are shown as shown in the second embodiment. It is also conceivable to combine the lifting of the non-contact type IC card 1 with the above. In that case, for example, the vertical mechanism 130 is used as means for floating the non-contact type IC card 1 to be inspected from the conveyor belts 10a and 10b, and then the air discharged from the cylinder when the piston of the vertical mechanism 130 is lowered is used. It can be considered that the non-contact type IC card 1 determined to be defective is blown from the air spray device 31.

  Further, in the above-described two embodiments, the side plates 40a and 40b are provided along the both sides of the conveyance path of the non-contact type IC card 1 by the conveyance belts 10a and 10b in the region where the inspection by the reader / writer 20 is performed. If an L-shaped jig that fixes the four corners of the non-contact type IC card 1 that has been conveyed to the area is arranged in the area where the inspection by the reader / writer 20 is performed, It is preferable that the non-contact type IC card 1 is not displaced in the transport direction when the non-contact type IC card 1 is lifted from the transport belts 10a and 10b.

  In the two embodiments described above, the non-contact type IC card 1 has been described as an example of the RF-ID medium to be inspected. However, the inspection target in the RF-ID media inspection apparatus of the present invention is The RF-ID medium is not limited to this, and may be a non-contact type IC tag, a non-contact type IC label, or the like as long as it is conveyed as a single piece on the conveyance belts 10a and 10b.
