Description

TECHNICAL FIELD The present invention relates to an IC tag holder mounted on a tableting machine used for forming tablets.

Rotary press machines are used to form tablets such as medicines and health foods. The rotary press machine can mount a mirror-finished upper punch, a lower punch and a die. When forming tablets using this rotary press machine, powder for forming a drug or the like is put into a die, and an upper punch and a lower punch are inserted into the die from above and below to press the powder. This causes the powder to compact and form tablets. Here, the shape of the tablet is determined by the concave shape of the upper punch and the lower punch, but in order to distinguish the upper punch, the lower punch and the die, the sliding of the piston motion such as the outer peripheral surface does not reach. An individual identification number or the like is stamped on the smooth surface.

A large number of sets are attached to the rotary press machine, with one set including such an upper punch, a lower punch and a die. Here, the mold set including the upper pestle, the lower pestle, and the die is associated with each other by the shape of the tablet, the stamp imprinted on the tablet, or the like. Therefore, it is necessary to install a mold set with the correct combination in the rotary press machine, but if a wrong mold set is installed in the rotary press machine, for example, a large amount of tablets with improper marking will be produced. Will be lost. Therefore, at present, the individual identification numbers of the upper punch, the lower punch, and the die are visually confirmed by the operator, and the die sets of the correct combination are mounted on the rotary press machine.

An example of such a rotary press device is disclosed in Patent Document 1.

Hereinafter, a rotary press device 10 (corresponding to a tableting machine), an upper punch 100, a lower punch 110, a die member 120 and an IC tag 200 according to an embodiment of the present invention will be described with reference to the drawings.

<1. Regarding the basic configuration of the rotary press machine 10>
FIG. 1 is a perspective view showing a partial configuration of the rotary press device 10. FIG. 2 is a perspective view showing the configuration of the rotor block 30, the upper pressure roller 50, and the lower pressure roller 60 in the rotary press device 10. FIG. 3 is a side sectional view showing the overall configuration of the rotary press device 10. As shown in FIGS. 1 to 3, the rotary press device 10 includes a rotor support 20, a rotor block 30, a roller support column 40, an upper pressure roller 50, a lower pressure roller 60, and a tablet discharge mechanism 70. The tag detection unit 80 is a main component, and in addition, a control unit (not shown) for controlling a drive source (described later) such as a motor and a roller pressing mechanism (described later) is provided.

The rotor support 20 is provided with a rotor mounting plate 21 (not shown) and a rotary shaft 22 located at the center of the rotor mounting plate 21. The rotary shaft 22 is connected to the unit shaft 36 of the rotor block 30. Further, the rotating shaft 22 is given a rotational force by a drive source such as a motor (not shown). Therefore, the rotor block 30 is supported by the rotor support portion 20 and can be rotationally driven.

The rotor block 30 includes the above-described unit shaft 36, and an upper guide portion 31, an upper punch rotor portion 32, a die rotor portion 33, a lower punch rotor portion 34, and a lower punch rotor portion 34 on the outer peripheral side of the unit shaft 36. The guide portion 35 is arranged. Unlike the upper punch rotor part 32 and the like, the upper guide part 31 is rotatably provided to the unit shaft 36 via a bearing or the like. Therefore, even when the upper punch rotor portion 32 and the like rotate together with the unit shaft 36, the upper guide portion 31 can be made non-rotatable by locking the upper guide portion 31 in a separate fixed portion.

The upper guide portion 31 includes a guide rail support board 311 and a pair of upper punch guide rails 312 are attached to the guide rail support board 311. The upper punch guide rail 312 is provided in an arc shape, and an inner circumferential convex portion 31a into which a constricted portion 103 of the upper punch 100 described later is fitted is provided on the inner circumferential side of the arc. As the upper guide portion 31 advances in the circumferential direction, the height of the inner circumferential convex portion 31a changes. Therefore, the upper punch 100 in which the inner circumferential convex portion 31a is fitted in the constricted portion 103 is configured to move up and down as the upper punch rotor portion 32 rotates.

The pair of upper punch guide rails 312 include a descending guide rail 312A for lowering the upper punch 100 toward the die member 120 and an ascending guide rail for retracting the upper punch 100 upward from the die member 120. And 312B. The upper pressure roller 50, which will be described later, is located between the lowering guide rail 312A and the ascending guide rail 312B.

The upper guide portion 31 is also provided with a support portion (not shown) that prevents the upper punch 100 from falling off the mounting hole 32a.

The upper punch rotor part 32 is a part that rotates integrally with the unit shaft 36 described above. The upper punch rotor portion 32 has a large number of mounting holes 32a, and the upper punch 100 is slidably held in each mounting hole 32a. The dozens of mounting holes 32a are provided, but the number is not limited.

The mortar rotor portion 33 is a disk-shaped member that holds the mortar member 120, and is provided between the upper pestle rotor portion 32 and the lower pestle rotor portion 34. The mortar rotor portion 33 has a large number of mounting holes 33a, and the mortar members 120 are held in the respective mounting holes 33a. The number of the mounting holes 33a is the same as the number of the mounting holes 32a described above. Further, the upper punch 100 held in the mounting hole 32a and the die member 120 held in the mounting hole 33a are provided so as to be positioned on the same axis.

The lower punch rotor part 34 is also a part that rotates integrally with the unit shaft 36 described above. The lower punch rotor portion 34 also has a large number of mounting holes 34a, and the lower punch 110 is slidably held in each of the mounting holes 34a. The number of the mounting holes 34a is the same as the number of the mounting holes 32a and the mounting holes 33a described above. Further, the upper punch 100 held in the mounting hole 32a, the die member 120 held in the mounting hole 33a, and the lower punch 110 held in the mounting hole 34a are provided so as to be positioned on the same axis.

The upper punch rotor part 32 and the lower punch rotor part 34 correspond to rotating members. It should be noted that only the upper punch rotor portion 32 may correspond to the rotating member, and only the lower punch rotor portion 34 may correspond to the rotating member, and both the upper punch rotor portion 32 and the lower punch rotor portion 34 may be arranged. It may be adapted to a punch member.

Further, the lower guide portion 35 is provided below the lower punch rotor portion 34. However, since the lower guide portion 35 is positioned below the lower punch rotor portion 34, it is supported at a position separate from the unit shaft 36. However, since the lower guide portion 35 engages with the lower punch 110, if the supporting state at a separate position is released, the lower guide portion 35 can be integrally attached to and detached from other portions of the rotor block 30 as a part of the rotor block 30.

Similarly to the above-mentioned upper guide portion 31, the lower guide portion 35 is also rotatably provided to the unit shaft 36 via a bearing or the like. Therefore, even when the lower punch rotor portion 34 and the like rotate together with the unit shaft 36, the lower guide portion 35 can be made non-rotatable by locking the lower guide portion 35 at a separate fixed portion.

By advancing the lower guide portion 35 along the circumferential direction, the height of the lower punch 110 can be changed similarly to the above-described upper guide portion 31. Therefore, the lower punch 110 mounted on the lower punch rotor portion 34 is configured to move up and down in accordance with the rotation of the lower punch rotor portion 34. In the configuration shown in FIG. 2, the lower guide portion 35 is configured to receive the head 114 of the lower punch 110 from the lower side, but other configurations may be adopted.

Next, the roller column 40, the upper pressure roller 50, and the lower pressure roller 60 will be described. The roller support column 40 is a portion that extends in the vertical direction, and rotatably supports the upper pressure roller 50 and the lower pressure roller 60. The roller column 40 has a roller pressing mechanism (not shown) for vertically moving the upper pressure roller 50 and the lower pressure roller 60 and applying a predetermined pressure.

The upper pressure roller 50 is located between the descending guide rail 312A and the ascending guide rail 312B as described above. As shown in FIGS. 1 and 2, the upper punch 100 inserted into the mounting hole 32 a projects above the upper surface of the upper punch rotor portion 32. Therefore, powder for forming tablets or the like is supplied to the insertion hole 123 of the die member 120, and then the upper punch 100 is pressed by the upper pressure roller 50, and the lower punch 110 described later causes the lower punch 110 to move. The tablet is pressed by being pressed by.

Here, as shown in FIGS. 1 and 2, a pair of upper pressure rollers 50 is provided. More specifically, the upper pressure roller 50 includes an upper preload roller 50A and an upper full pressure roller 50B. The upper preloading roller 50A preliminarily pressurizes the powder supplied to the insertion hole 123 of the die member 120. The upper main pressing roller 50B is for full-scale pressing of the powder that has been preliminarily pressed. The upper preload roller 50A and the upper full pressure roller 50B are located on the head 104 of the upper punch 100, and push the upper punch 100 to a position where the insertion hole 123 has a predetermined depth.

The lower pressure roller 60 also includes a lower pre-pressure roller 60A similar to the upper pre-pressure roller 50A and a lower main pressure roller 60B similar to the upper main pressure roller 50B. The configurations of the lower preloading roller 60A and the lower main pressing roller 60B are similar to those of the above-described upper preloading roller 50A and the upper main pressing roller 50B, and thus detailed description thereof will be omitted.

The rotary press device 10 is also provided with a tablet discharging mechanism 70. The tablet discharging mechanism 70 is a mechanism for discharging the tablets, which are pressure-molded inside the insertion hole 123 and discharged from the insertion hole 123 by the lower punch 110, to the outside.

The rotary press device 10 also includes a tag detection unit 80 (see FIG. 13). The tag detection unit 80 detects an IC tag 200 described later (the IC tag 200 corresponds to an IC tag holder. Further, in FIG. 13, the IC tag 200a that is the first configuration example of the IC tag 200 is Although it is illustrated, the same applies to other examples of the IC tag 200 described later). In addition, in FIG. 13, the head 104 of the upper punch 100 is shown as an example of a portion facing the tag detection unit 80. However, it goes without saying that the tag detection unit 80 may be arranged so as to face the head 114 of the lower punch 110 and the outer peripheral surface of the cylindrical portion 121 of the die member 120.

The tag detection unit 80 described above is provided with a coil antenna 81 and a cable 82. The coil antenna 81 is a portion facing the IC inlet 220 of the IC tag 200 fitted into the tag insertion holes 104b and 114b of the upper punch 100 and the lower punch 110, for example. The magnetic field line φ passes between the coil antenna 81 and the coil antenna 223 facing the coil antenna 223 existing in the IC inlet 220. There is also).

The cable 82 is electrically connected to the coil antenna 81 and also to the reader device 300. The reader device 300 is connected to the host system 301 via a network or the like. The upper system 301 stores data such as the IDs of the works (upper punch 100, lower punch 110 and die member 120) to which the IC tag 200 is attached and the start date of use. If there is no response from the IC tag 200, it is determined that the work (upper punch 100, lower punch 110 and die member 120) has failed or has reached the end of its life.

Here, when it is determined by the host system 301 that the work has reached the end of its life due to reasons such as no response of the work (upper punch 100, lower punch 110 and die member 120) or reaching the upper limit of the number of shots, The host system 301 can construct a system that can automatically order works. Further, even if the life of the work is not yet reached, if it is determined that the life of the work is approaching, it is possible to construct an automatic ordering system that considers the delivery date of the work.

It should be noted that the tag detection unit 80 may include the reader device 300 as a small integrated unit, but may not include the reader device 300 as a large separate unit.

<2. Upper punch 100, lower punch 110 and die member 120>
FIG. 4 is a perspective view showing the upper punch 100 as viewed from above. FIG. 5 is a perspective view showing the state where the upper punch 100 is viewed from the lower side. FIG. 6 is a side view of the upper punch 100, the lower punch 110, and the die member 120, and is a view showing a state in which these are arranged on the same axis.

The upper punch 100 and the lower punch 110 correspond to punch members. Only the upper punch 100 may correspond to the punch member, only the lower punch 110 may correspond to the punch member, and both the upper punch 100 and the lower punch 110 may correspond to the punch member. good. The upper punch 100 is made of metal such as steel, but may be subjected to a predetermined surface treatment such as chromium nitride coating.

As shown in FIGS. 4 to 6, the upper punch 100 has a main body portion 101, an insertion portion 102, a constricted portion 103, and a head portion 104. The main body 101 is the longest cylindrical portion of the upper punch 100. The body portion 101 is a portion that is inserted into the mounting hole 32a of the upper punch rotor portion 32 described above, and is slidable inside the mounting hole 32a. The insertion portion 102 is a portion to be inserted into the insertion hole 123 of the die member 120 and has a diameter corresponding to the insertion hole 123.

A tablet pressing portion 102a is provided on the end surface of the insertion portion 102. An example of the tablet pressurizing section 102a is, for example, a concave shape that is curved corresponding to the most popular lens type. However, a protrusion may be present in the central portion of the tablet pressing portion 102a corresponding to the ring-shaped tablet, and the shape of the tablet pressing portion 102a is formed corresponding to other tablets having a special shape. It may be done.

Further, the constricted portion 103 is a portion that is provided between the main body portion 101 and the head portion 104 and has a smaller diameter than these. Therefore, it is possible to hold the upper punch 100 through the constricted portion 103.

The head 104 is a portion located above the upper punch 100 and has a larger diameter than the constricted portion 103. On the upper surface side of the head 104, a sliding surface 104a on which the upper pressure roller 50 as described above slides is provided. The sliding surface 104a is provided in a curved shape such that the central portion thereof projects the most upward.

The sliding surface 104a is provided with a tag insertion hole 104b. An IC tag 200 described later is inserted into the tag insertion hole 104b. However, the upper pressure roller 50 slides on the sliding surface 104a as described above. Therefore, as shown in FIG. 4, the sliding surface 104a and the IC tag 200 may be provided flush with each other, but this portion receives a high pressure due to the impact from the upper pressure roller 50. Therefore, it is preferable that the impact of the direct impact on the IC tag 200 be released by slightly lowering the surface of the IC tag 200 with respect to the surface of the sliding surface 104a. A contour of a boundary between the tag insertion hole 104b and the IC tag 200 exists on the sliding surface 104a.

FIG. 7 is an enlarged side view of the tag insertion hole 104b and a side sectional view showing the IC tag 200 inserted into the tag insertion hole 104b. The IC tag 200 corresponds to an IC tag holder. In FIG. 7, an IC tag 200a that is a first configuration example of the IC tag 200 is illustrated (another configuration example of the IC tag 200 will be described later). As shown in FIG. 7, the inner peripheral surface of the tag insertion hole 104b is formed by a ring-shaped acute-angled convex portion rather than a screw-shaped convex portion, in other words, by a plurality of closed circular convex portions. A ring-shaped convex portion 104b1 is provided.

The IC tag 200a has a tag holding portion 210a and an IC inlet 220. The tag holding portion 210a is made of a resin made of a dielectric resin material. A large impact is applied to the upper punch 100, the lower punch 110, and the die member 120 when forming a tablet or the like, and the number of times is, for example, 1 million times. Therefore, it is necessary that the IC tag 200a does not float up or fall out of the tag insertion hole 104b no matter how many times it receives a large impact. In the configuration as shown in FIG. 7, when the IC tag 200a is fitted in a fixed position of the tag insertion hole 104b, the inner peripheral surface of the tag insertion hole 104b is formed on the outer periphery of the tag holding portion a formed of a resin material. Since the acute-angled convex portions of the ring-shaped convex portion 104b1 provided on the above-mentioned bite bite in multiple stages, it is possible to prevent the drop-out with a simple configuration due to the high resistance to this biting.

Further, after the IC tag 200a is fitted into a fixed position of the tag insertion hole 104b and then a resin or the like is further enclosed in a minute space generated therebetween, it is possible to further prevent the IC tag 200a from falling off.

Further, as described above, the upper punch 100, the lower punch 110, and the die member 120 are subjected to a large impact when a tablet or the like is formed, and the number of times reaches, for example, 1 million times, so that the IC tag 200a. The IC inlet 220 is subjected to a strong impact many times. As a result, for example, the coil antenna built in the IC inlet 210 has a poor connection, breaks, or the IC chip fails (the internal structure of the IC inlet 210 will be described later with reference to FIG. 12). It is necessary to prevent the occurrence of failures such as

Therefore, the IC inlet 220 of the IC tag 200a is installed at an angle close to a right angle with respect to a surface parallel to the sliding surface 104a. As a result, the IC inlet 220 is less susceptible to the impact given to the surface parallel to the sliding surface 104a. The installation angle of the IC inlet 220 with respect to the plane parallel to the sliding surface 104a is preferably 90 degrees, but may be in the range of 45 degrees to 90 degrees to 135 degrees, for example. Further, the IC inlet 220 of the IC tag 200a is installed while avoiding the central axis of the IC tag 200a. Details of the IC tag 200a and communication with the tag detection unit 80 of the rotary press device 10 will be described later.

FIG. 8 is a perspective view showing a state where the lower punch 110 is viewed from the upper side. FIG. 9 is a perspective view showing a state where the lower punch 110 is viewed from the lower side. The lower punch 110 is made of the same material as the upper punch 100 described above, but may be made of a different material. Like the upper punch 100 described above, the lower punch 110 also has a main body portion 111, an insertion portion 112, a constricted portion 113, and a head portion 114.

Here, as is clear from FIGS. 8 and 9, the insertion portion 112 is provided longer than the insertion portion 102 of the upper punch 100. That is, the tablet that is pressure-molded inside the insertion hole 123 of the die member 120 needs to be discharged from the insertion hole 123. Therefore, the insertion portion 112 is provided to have the same length as the axial length of the insertion hole 123 or longer than the axial length of the insertion hole 123. The insertion section 112 is also provided with a tablet pressing section 112a, and the tablet pressing section 112a has the same configuration as the tablet pressing section 102a described above.

When the lower punch 110 and the die member 120 are mounted on the rotary press device 10, at least a part of the insertion portion 112 may be always inserted into the insertion hole 123 of the die member 120. it can. This is because the tablet pressurizing unit 112a of the insertion unit 112 needs to receive the powder charged in the insertion hole 123 from the lower side.

The sliding surface 114a of the head 114 of the lower punch 110 is provided with a tag insertion hole 114b similar to the tag insertion hole 104b described above. A ring-shaped convex portion 114b1 is also provided in this similar tag insertion hole 114b (FIG. 7). The main body 111 and the constricted portion 113 have the same configurations as the main body 101, the insertion portion 102, the constricted portion 103, and the head 104 described above. Therefore, description of these is omitted.

Next, the die member 120 will be described. FIG. 10 is a perspective view showing the configuration of the die member 120. As shown in FIGS. 7 and 10, the mortar member 120 includes a tubular portion 121 formed in a tubular shape. On the outer peripheral side of the tubular portion 121, a central portion in the height direction is provided. A circumferential guide recess 122 is provided. Due to the existence of the guide recesses 122, even when the die member 120 is inserted into the attachment hole 33a of the die rotor portion 33, it is possible to prevent the die member 120 from moving inside the attachment hole 33a.

Further, in the die member 120, an insertion hole 123 exists on the inner side surrounded by the tubular portion 121. The insertion hole 123 is a hole portion into which the insertion portion 102 and the insertion portion 112 described above are inserted, and has an inner diameter corresponding to the insertion portion 102 and the insertion portion 112 described above. That is, the insertion portion 102 and the insertion portion 112 have a clearance that allows them to slide in the insertion hole 123.

Here, on the outer peripheral surface of the tubular portion 121, a tag insertion hole 124 is provided on the upper side or the lower side of the guide recess 122 so as to be recessed toward the inner diameter side. The tag insertion hole 124 is provided with a ring-shaped convex portion 124a, like the tag insertion holes 104b and 114b described above (FIG. 7).

<3. About IC tag 200>
Next, the IC tag 200 will be described. FIG. 11 is a perspective view showing a configuration of an IC tag 200a which is a first configuration example of the IC tag 200. As shown in FIG. 11, the IC tag 200a has a tag holding portion 210a and an IC inlet 220. The tag holding portion 210a is made of a resin made of a dielectric resin material. As such a resin, for example, polyether ether ketone (PEEK) can be cited, but other resins may be used as the material. In addition, for example, in order to improve the flow of the magnetic path, the tag holding unit 210a may be made of a powder of a magnetic material or a mixture of a powder of a dielectric material and a magnetic material in addition to the dielectric resin material. good.

The tag holding portion 210a is provided in a cylindrical shape, and the diameter thereof is the size corresponding to the tag insertion holes 104b, 114b, and 124 described above. On the outer peripheral surface of the columnar tag holding portion 210a, the sharp convex portions of the ring-shaped convex portions 104b1, 114b1, 124a of the above-mentioned tag insertion holes 104b, 114b, 124 bite in multiple stages. With a simple configuration, the IC tag 200a has a configuration in which it is difficult for the IC tag 200a to come off from the tag insertion holes 104b, 114b, and 124.

Further, as shown in FIG. 7, the IC inlet 220 has a right angle (90 degrees) or an angle within a predetermined range (45 degrees to 90 degrees, or 90 degrees to 135 degrees) with respect to a plane parallel to the sliding surface 104a. Installed). As a result, it is possible to reduce the impact that the IC inlet 220 receives due to the impact on the surface parallel to the sliding surface 104a. In order to reduce the impact on the IC inlet 220, the IC inlet 220 is preferably 45 degrees or more, and 60 degrees or more and 120 degrees or less, that is, 90 degrees, with respect to the plane parallel to the sliding surface 104a. It is particularly preferable that the temperature is within plus or minus 30 degrees. This is because when the angle is 60 degrees or more and 120 degrees or less, the projected area of the IC inlet 220 on the sliding surface 104a becomes 1/2 or less of the length of one side of the IC inlet 220, and the impact can be significantly reduced to half or less. ..

Next, the IC inlet 220 will be described. FIG. 12 is a perspective view showing the structure of the IC inlet 220. As shown in FIG. 12, the IC inlet 220 includes an IC tag substrate 221, an IC chip 222, and a coil antenna 223. The IC tag substrate 221 is formed in a substantially rectangular flat plate shape. As the IC tag substrate 221, for example, a glass epoxy substrate or a resin film such as PET can be used. The IC tag substrate 221 has an IC chip 222 and a coil antenna 223, of which the IC chip 222 stores various data.

FIG. 13 shows the tag detection unit 80 of the rotary press device 10, and shows the transformer coupling between the coil antenna 81 of the tag detection unit 80 and the two coils of the coil antenna 223 inside the IC inlet 220 of the IC tag 200a. FIG. 6 is a diagram showing a state of a mutual induction magnetic field φ for As shown in FIG. 13, in the present embodiment, the IC inlet 220 is installed avoiding the central axis of the IC tag 200a. When the IC inlet 220 is arranged at a position passing through the center axis of the IC tag 200a, there is no magnetic field φ penetrating the coil antenna 223 built in the IC inlet 220, so that mutual induction does not occur and tag communication can be performed. It's gone. By arranging the IC inlet 220 at an angle close to a right angle with respect to a plane parallel to the sliding surface 104a while avoiding the central axis of the IC tag 200a, the coil antenna 81 of the tag detection unit 80 and the coil of the IC tag 200a are arranged. The antenna 223 is coupled with the mutual induction magnetic field φ. As a result, it becomes possible to read information from and write information to the IC chip 222 via the coil antenna 223. FIG. 13 shows that the mutual induction magnetic fields φ are distributed symmetrically with respect to the central axis, and of these, the side closer to the IC inlet 220 mutually induces and contributes to tag communication.

Further, as shown in FIG. 13, the surface of the IC tag 200a is lower than the sliding surface 104a by a distance s, in other words, with respect to the depth of the tag insertion holes 104b, 114b, and 124, When the height of the IC tag 200a is lowered by s, the IC tag 200a is less likely to receive an impact when the sliding surface 104a is strongly hit, which is preferable.

Further, when the IC tag 200a is fitted into the tag insertion holes 104b, 114b, and 124, the air between the IC tag 200a is released so that the air can be easily fitted in the IC tag 200a, as shown in FIG. The groove 351 may be provided. Although FIG. 14 illustrates that four air escape grooves 351 are provided, the number of air escape grooves 351 is not limited to this.

Next, an IC tag 200b that is a second configuration example of the IC tag 200 will be described with reference to FIGS. FIG. 15 is a perspective view showing the configuration of the IC tag 200b. FIG. 16 is a diagram for explaining communication between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220 of the IC tag 200b.

In the above-described IC tag 200a, the IC is formed at an angle close to a right angle with respect to the sliding surface 104a, the sliding surface 114a, or a surface parallel to the surface of the tubular portion 121 (hereinafter referred to as the sliding surface 104a). Since the inlet 220 is arranged, the portion of the tag detecting unit 80 where the coil antenna 223 faces the surface of the coil antenna 81 is small, and the portion of the mutual induction magnetic field φ that contributes to tag communication is reduced. On the other hand, the IC tag 200b of FIGS. 15 and 16 further improves the communication performance between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220.

As shown in FIG. 15, the IC tag 200b has a tag holding portion 210b and an IC inlet 220, as with the IC tag 200a, and further includes a reader communication antenna 401, an inlet magnetic field coupling antenna 402, and , And has a relay cable 403 for connecting them. The reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the relay cable 403 correspond to an antenna repeater. The reader communication antenna 401 is arranged so as to face the coil antenna 81 of the tag detection unit 80, and the inlet magnetic field coupling antenna 402 is arranged so as to face the IC inlet 220 immediately.

In the IC tag 200b, the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the relay cable 403 connecting them form a circuit through which a high-frequency current necessary for tag communication flows. As a result, the coil antenna 81 of the tag detection unit 80 and the reader communication antenna 401 can be made to face each other, and the inlet magnetic field coupling antenna 402 connected to the reader communication antenna 401 by the relay cable 403 is made to directly face the IC inlet 220. be able to. That is, in the IC tag 200b, as shown in FIG. 16, the reader communication antenna 401 and the coil antenna 81 of the tag detection unit 80 are transformer-coupled, and the inlet magnetic field coupling antenna 402 and the coil antenna 223 of the IC inlet 220 are coupled. Are designed to be trans-coupled.

With such a configuration, the IC inlet 220 of the IC tag 200b can be installed separately from the surface of the IC tag 200b on the side of the sliding surface 104a and the like. Therefore, the IC tag 200b is configured to further improve the sensitivity of tag communication and prevent the IC inlet 220 from being damaged due to the impact that the IC tag 200b receives by hitting or the like. Further, in the IC tag 200b, even if the reader communication antenna 401 is disconnected due to the impact that the IC tag 200b receives by hitting or the like, as long as the IC inlet 220 does not fail, for example, the tag holding of the IC tag 200b is held. By carefully digging out the IC inlet 220 from the portion 210b, it becomes possible to read the information held in the IC chip 222 of the IC inlet 220.

The entire circuit length of the reader communication antenna 401 and the inlet magnetic field coupling antenna 402 (not including the relay cable 403) is set to a negligible length with respect to the high-frequency wavelength λ used for tag communication, so that the sensitivity decreases due to the phase difference. Can be ignored. For example, when operating at a frequency of 920 MHz, as a guideline, by setting the total wiring length of the circuit to about 40 mm, good communication can be performed without being affected by the sensitivity decrease due to the phase difference. Is.

15 and 16, the reader communication antenna 401 and the inlet magnetic field coupling antenna 402 are illustrated as a coiled antenna having one turn, but the number of turns of the coil is not limited to this, and generally, The smaller the antenna diameter, the greater the number of turns. For example, when operating at a frequency of 920 MHz, the number of turns is at most 2-3. Further, it goes without saying that the IC tag 200b may also be provided with the air escape groove 351 described with reference to FIG.

As shown in FIGS. 15 and 16, in the IC tag 200b, the IC inlet 220 is installed at a right angle or an angle close to a right angle with respect to a surface parallel to the sliding surface 104a and the like. The mutual induction magnetic field φ generated between the communication antenna 401 and the coil antenna 81 of the tag detection unit 80 and the mutual induction magnetic field φ generated between the inlet magnetic field coupling antenna 402 and the coil antenna 223 of the IC inlet 220 are independent. You can consider it as doing. Further, in the IC tag 200b, the IC inlet 220 may be installed at any position in any direction as long as the mutual induction magnetic fields φ overlap and do not adversely affect communication. Thus, as shown in FIGS. 15 and 16, the IC tag 200b realizes good communication, and the size of the diameter of the IC tag 200b is set not to the diameter of the circumscribed circle of the IC inlet 220 but to the IC inlet 220b. The diameter of the inscribed circle of 220 or one side of the IC inlet 220 can be made equal, and the size can be further reduced.

Further, the relay cable 403 can reduce the attenuation by arranging the insulating coated wires at regular intervals, that is, by following a cable design well known in electromagnetics. The relay cable 403 may be a relay cable 403a including two conductors (parallel ribbon cables) in which a core wire 421 is covered with an insulating coating 422, as shown in FIG. 17A shows a side view of the relay cable 403a, and FIG. 17B shows a cross-sectional view of the relay cable 403a.

Further, as shown in FIG. 18, the relay cable 403 may be a relay cable 403b made up of two conductors in which a single core wire 421 is covered with an insulating coating 422 (twisted pair cable). .. 18A shows a side view of the relay cable 403b, and FIG. 18B shows a sectional view of the relay cable 403b. When the relay cable 403b is used, due to the expansion and contraction effect of the twisted structure of the cable, the impact due to the impact on the sliding surface 104a or the like is less likely to be transmitted to the IC inlet 220, and the impact cushioning effect can be achieved.

Further, as shown in FIG. 19, the relay cable 403 may be a relay cable 403c including one core wire 421 covered with an insulating coating 422 and an outer conductor 421b (coaxial cable) covering these surfaces. 19A is a side view of the relay cable 403c, and FIG. 19B is a cross-sectional view of the relay cable 403c.

Further, the impedance of the reader communication antenna 401 and the inlet magnetic field coupling antenna 402 (that is, the impedance of the micro coil antenna known in electromagnetics) and the impedance of the relay cable 403 (that is, the parallel two-wire transmission cable known in electromagnetics). (Impedance matching) with the characteristic impedance (such as) allows connection with less loss. Also, the shorter the relay cable 403, the less the loss.

Further, the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the relay cable 403 connecting them may be configured by using a sheet substrate 441 as shown in FIG. That is, the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the relay cable 403 connecting them may be printed on the sheet substrate 411. When it is desired that the relay cable 403 has a twisted conductor portion like the relay cable 403b, it can be realized by using the sheet substrate 441 as a double-sided substrate, and the relay cable 403 portion printed on the sheet substrate 441 can be realized. You may twist.

Next, FIG. 21 is a perspective view showing a configuration of an IC tag 200c which is a third configuration example of the IC tag 200. As shown in FIG. 21, the IC tag 200c has a tag holding portion 210c, an IC inlet 220, an inlet magnetic field coupling antenna 402, and a relay cable 403, like the IC tags 200a and 200b. A reader communication antenna 401a is provided instead of the reader communication antenna 401.

The reader communication antenna 401a has the same function as the reader communication antenna 401, but has a large thickness in the direction orthogonal to the plane parallel to the sliding surface 104a of the IC inlet 220. The upper punch 100, the lower punch 110, and the die member 120 may be cut for fine adjustment in the finishing process during manufacturing. In addition, the upper punch 100, the lower punch 110, and the die member 120 may wear their surfaces during use. The thickness of the leader communication antenna 401a is a predetermined thickness determined by the thickness of the upper punch 100, the lower punch 110, and the die member 120 that are cut during the manufacturing process, and the thickness that is considered to be worn in the required durability performance. A thickness equal to or larger than the thickness or line width of the reader communication antenna 401a on a surface parallel to the sliding surface 104a or the like is preferable. It is easy to handle the thickness of the reader communication antenna 401a about 1 to 2 times the thickness or the line width, but the thickness is not limited to this.

As a result, the reader communication antenna 401a can face the coil antenna 81 of the tag detection unit 80 as close as possible, and can retain its function even if it is slightly cut, thereby improving resistance to wear. Is made possible. The thickness of the reader communication antenna 401a described above is the height in a cross section orthogonal to the sliding surface 104a and the like, and when the reader communication antenna 401a is polished or worn, its width does not change significantly, so that the sliding surface does not change significantly. It is preferable that the cross section orthogonal to 104a or the like is rectangular or a shape close to a rectangle, rather than a circle.

As described above, the IC tag 200c can further improve the sensitivity of tag communication and prevent the IC inlet 220 from being damaged due to the impact or abrasion received by a hit or the like, and can have resistance to cutting or abrasion. Is configured.

Note that, in FIG. 21, the reader communication antenna 401 and the inlet magnetic field coupling antenna 402 are illustrated as a coiled antenna with one turn, but the number of turns of the coil is not limited to this, and generally the antenna diameter is The smaller the number, the more turns. However, for example, when operating at a frequency of 920 MHz, the number of turns is at most about 2 to 3.

Further, in the IC tag 200c, as in the case of the IC tag 200b, the IC inlet 220 is installed in any direction and in any position as long as the mutual induction magnetic fields φ do not overlap and adversely affect communication. It doesn't matter. Further, it goes without saying that the IC tag 200c may also be provided with the air escape groove 351 described with reference to FIG.

Note that in the IC tag 200c, communication between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220 of the IC tag 200c is basically the same as that described with reference to FIG. , Its detailed description is omitted.

Next, an IC tag 200d which is a fourth configuration example of the IC tag 200 will be described with reference to FIGS. FIG. 22 is a perspective view showing the configuration of the IC tag 200d. FIG. 23 is a diagram for explaining communication between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220 of the IC tag 200d.

As shown in FIG. 22, the IC tag 200d has a tag holding portion 210d, an IC inlet 220, a reader communication antenna 401a, and an inlet magnetic field coupling antenna 402, like the IC tags 200a to 200c. In addition, the relay cable 403b is twisted an odd number of times (for example, once or three times). In the IC tag 200d, the IC inlet 220 is installed substantially parallel to the sliding surface 104a and the like (that is, the parallel includes some error). That is, in the IC tag 200d, the length in the direction (axial direction) orthogonal to the plane parallel to the sliding surface 104a and the like can be shortened as compared with the IC tags 200a to 200c.

As shown in FIG. 23, in the IC tag 200d, the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the coil of the IC inlet 220 are twisted by the relay cable 403b that is twisted an odd number of times (for example, once or three times). The directions of the high frequency currents flowing through the antenna 223 are the same. That is, the mutual induction magnetic field φ generated by the proximity of the coil antenna 81 of the tag detection unit 80 commonly penetrates the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the coil antenna 223 of the IC inlet 220. Due to this electromagnetic coupling, tag communication is executed well.

22 and 23 are illustrated as having the reader communication antenna 401a, it is needless to say that the reader communication antenna 401 can be used. Further, in FIGS. 22 and 23, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 are shown as a coiled antenna having one turn, but the number of turns of the coil is not limited to this, and generally, The smaller the antenna diameter, the greater the number of turns. However, for example, when operating at a frequency of 920 MHz, the number of turns is at most about 2 to 3. Needless to say, the IC tag 200d may also be provided with the air escape groove 351 described with reference to FIG.

With such a configuration, the IC tag 200d has good communication performance, and is at a right angle to a plane parallel to the sliding surface 104a or the like as compared with the above-described IC tags a to IC tag c. It is possible to reduce the height in the direction. The smaller the IC tag 200, the higher the strength of the upper punch 100, the lower punch 110, and the die member 120. Therefore, the strength of the upper punch 100, the lower punch 110, and the die member 120 can be maintained by using the IC tag 200d. It will be possible. However, in the above-mentioned IC tags 200a to 200c, the diameter in the outer peripheral direction is almost double the route, as compared with the case where the IC inlet is installed at a right angle to a plane parallel to the sliding surface 104a or the like. Become.

Next, an IC tag 200e, which is a fifth configuration example of the IC tag 200, will be described with reference to FIGS. 24 and 25. FIG. 24 is a perspective view showing a configuration of an IC tag 200e which is a fifth configuration example of the IC tag 200. FIG. 25 is a diagram for explaining communication between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220 of the IC tag 200e.

For example, when it is desired to inexpensively manufacture the configuration using the sheet substrate 441 described with reference to FIG. 20, it is preferable to use the relay cable 403a having no twisted portion like the relay cable 403b. In addition, it may be required to install the IC inlet 220 substantially parallel to the sliding surface 104a and the like due to manufacturing reasons. The IC tag 200e satisfies such requirements while having good communication performance.

As shown in FIG. 24, the IC tag 200e has a tag holding portion 210e, an IC inlet 220, a reader communication antenna 401a, and an inlet magnetic field coupling antenna 402, like the IC tags 200a to 200d. At the same time, a relay cable 403a having no twist is used. In the IC tag 200e, the IC inlet 220 is installed substantially parallel to the sliding surface 104a and the like, as in the IC tag 200d. Note that the relay cable 403c or the relay cable 403b twisted an even number of times may be used instead of the relay cable 403a having no twist.

In the IC tag 200e, since the relay cable 403a having no twist (or the relay cable 403c or the relay cable 403b twisted by an even number of times) is used, as shown in FIG. 25, the reader communication antenna is used. The direction of the high-frequency current flowing through 401 is different from the direction of the high-frequency current flowing through the inlet magnetic field coupling antenna 402 and the coil antenna 223 of the IC inlet 220.

Therefore, in the IC tag 200e, as shown in FIG. 24, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 repel each other's mutual induction magnetic fields φ and cancel each other out, which adversely affects communication. It is installed at a distance h or more to prevent this. The distance h corresponds to the diameters of the reader communication antenna 401 and the inlet magnetic field coupling antenna 402, but it goes without saying that they may be further separated.

In the IC tag 200e, as shown in FIG. 25, the reader communication antenna 401a is used for transformer coupling with the coil antenna 81 of the tag detection unit 80, and the inlet magnetic field connected to the reader communication antenna 401a by the relay cable 403. The coupling antenna 402 is transformer-coupled to the coil antenna 223 of the IC inlet 220. Then, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 are separated from each other by a distance h or more so that their transformer couplings are independent from each other.

By having such a configuration, the IC tag 200e has good communication performance, and when the configuration using the sheet substrate 441 described with reference to FIG. This makes it possible to deal with the case where the IC inlet 220 is required to be installed substantially parallel to the sliding surface 104a and the like.

24 and 25, the reader communication antenna 401a is shown as an example, but it goes without saying that the reader communication antenna 401 can be used. Further, in FIG. 24 and FIG. 25, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 are illustrated as a coil antenna with one turn, but the number of turns of the coil is not limited to this, and generally, The smaller the antenna diameter, the greater the number of turns. However, for example, when operating at a frequency of 920 MHz, the number of turns is at most about 2 to 3. Needless to say, the air escape groove 351 described with reference to FIG. 14 may be provided in the IC tag 200e as well.

Next, an IC tag 200f which is a sixth configuration example of the IC tag 200 will be described with reference to FIGS. FIG. 26 is a perspective view showing the configuration of the IC tag 200f. FIG. 27 is a diagram for explaining the magnetic field blocking plate 461 of the IC tag 200f. FIG. 28 is a diagram for explaining communication between the coil antenna 81 of the tag detection unit 80 and the coil antenna 223 of the IC inlet 220 of the IC tag 200f.

For example, when it is desired to inexpensively manufacture the configuration using the sheet substrate 441 described with reference to FIG. 20, it is preferable to use the relay cable 403a having no twisted portion like the relay cable 403b. Also, due to manufacturing reasons, it may be required that the IC inlet 220 be installed substantially parallel to the sliding surface 104a and the like. In contrast to the above-described IC tag 220e that satisfies such requirements, the IC tag 200f can be designed so that the height (dimension) in the direction orthogonal to the sliding surface 104a or the like is lower (shorter) than the IC tag 220e. Is configured.

As shown in FIG. 26, the IC tag 200f has a tag holding portion 210f, an IC inlet 220, a reader communication antenna 401a, and an inlet magnetic field coupling antenna 402, like the IC tags 200a to 200e. A relay cable 403a is also used, and a magnetic field blocking plate 461 is provided between the reader communication antenna 401a and the inlet magnetic field coupling antenna 402. As shown in FIG. 27, the magnetic field blocking plate 461 has a plate-like shape in which the metal layer 472 is sandwiched by using two insulating layers 471, and the magnetic field generated on both surface sides thereof is the same as the magnetic field of the other surface. The magnetic field is blocked by the metal layer 472 so as not to affect each other.

Since the relay cable 403a having no twist is used also in the IC tag 200f, as shown in FIG. 28, the direction of the high-frequency current flowing through the reader communication antenna 401, the inlet magnetic field coupling antenna 402, and the IC inlet 220. The direction of the high frequency current flowing through the coil antenna 223 is different. However, since the magnetic field blocking plate 461 is installed between the reader communication antenna 401a and the inlet magnetic field coupling antenna 402, the IC tag 200f uses the reader communication antenna 401a and the coil antenna 81 of the tag detection unit 80. In addition to being transformer-coupled, the reader communication antenna 401a and the relay magnetic field coupling antenna 403 are coupled to the coil antenna 223 of the IC inlet 220 by the inlet magnetic field coupling antenna 402 so that the transformer couplings are independent of each other. It is configured. Thus, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 can be installed closer than the distance h in FIG.

26 and 28 are shown as having the reader communication antenna 401a, it goes without saying that the reader communication antenna 401 can be used. Further, in FIGS. 26 and 28, the reader communication antenna 401a and the inlet magnetic field coupling antenna 402 are illustrated as a coiled antenna having one turn, but the number of turns of the coil is not limited to this, and generally, The smaller the antenna diameter, the greater the number of turns. However, for example, when operating at a frequency of 920 MHz, the number of turns is at most about 2 to 3. Needless to say, the air escape groove 351 described with reference to FIG. 14 may be provided in the IC tag 200f.

According to the IC holder (IC tag 200a to IC tag 200f) having the above-described structure, the IC holders are embedded in the heads 104 and 114 of the upper punch 100 and the lower punch 110 of the rotary press apparatus 10 for pressure-molding powder, and the ICs IC tags 200a to 200f in which an IC inlet 220 having a chip 222 and a coil antenna 223 is incorporated, the IC inlet 220 being substantially parallel to the central axis of the IC tags 200a to 200f, and The reader magnetic communication antennas 401 and 401a for communicating with the tag detection unit 80 and the coil antenna 81, and the inlet magnetic field coupling antenna 402 for communicating with the IC inlet 220 are installed at a position shifted from the central axis by a predetermined distance. , And an antenna repeater having a relay cable 403 for connecting them, the reader communication antennas 401, 401a are installed on the head side 104, 114 surface side of the upper punch 100 and the lower punch 110 of the rotary press machine 10, The inlet magnetic field coupling antenna 402 is installed in close proximity to an IC inlet 220 installed at a predetermined depth from the surfaces of the heads 104 and 114 of the upper punch 100 and the lower punch 110 of the rotary press machine 10. That is, the IC tag 200 is attached to the upper punch 100 and the lower punch 110. Therefore, by reading the data of the IC chip 222 provided in the IC tag 200 attached to the upper punch 100 and the lower punch 110 and writing the data in the IC chip 222, the upper punch 100 and the lower punch 110 can be moved to the rotary press machine 10. It becomes possible to prevent a mistake in mounting when mounting.

That is, which die member 120 or lower punch 110 is to be used for a certain upper punch 100 is often predetermined. On the other hand, at present, the upper punch 100 and the upper punch 100 are mounted on the rotary press device 10 while being visually confirmed. In that case, a human error such as a mounting error may occur. In particular, the individual identification numbers stamped on the upper punch 100 and the lower punch 110 are often stamped with small letters, and are often difficult to see.

When such a mounting error occurs, for example, a large number of tablets having a marking error or the like are produced, or a large number of tablets that are pressure-molded at a pressure different from the prescribed pressing force are produced. There may be problems of.

On the other hand, in the present embodiment, the IC tags 200 are attached to the upper punch 100 and the lower punch 110, and the data of the IC chip 222 included in the IC tags 200 is read or the IC chip 222 receives the data. By writing, it becomes possible to prevent a mounting error when mounting the upper punch 100 and the lower punch 110 to the rotary press device 10. Therefore, it is possible to prevent problems such as mass production of tablets with marking errors, and mass production of pressure-molded tablets at a pressure different from the prescribed pressing force. ..

Further, when the upper punch 100 and the lower punch 110 are mounted on the rotary press device 10, it is not necessary to read the individual identification number engraved in small letters. Therefore, the upper punch 100 and the lower punch 110 can be quickly attached to the rotary press device 10.

In addition, in the present embodiment, the life of the upper punch 100 and the lower punch 110 can be managed. That is, high pressure is applied to the heads 104 and 114 of the upper punch 100 and the lower punch 110 when forming tablets. Therefore, the heads 104 and 114 are worn according to the number of times of tableting. Then, when the amount of wear exceeds a predetermined amount, the pressing force at the time of molding changes by that amount, resulting in defective molding of tablets, and unclear marking on tablets, and the like. There is a risk that tablets will be produced in large quantities.

However, in this embodiment, since the IC tag 200 is attached to the upper punch 100 and the lower punch 110, the upper punch 100 and the lower punch 110 are used by using the data of the IC chip 222 included in the IC tag 200.

Therefore, although it is easy to handle 1 to 2 times, it is not limited to this.

The upper pestle 100 and the lower pestle 110 may be cut for fine adjustment in the finishing process during manufacturing. Further, the surfaces of the upper punch 100 and the lower punch 110 may be worn during the use process. Therefore, the leader communication antenna 401a has a thickness determined by the thickness of the upper punch 100, the lower punch 110 and the die member 120 that are cut during the manufacturing process and the thickness that is considered to be worn in the required durability performance, for example, the leader communication antenna 401a. By having a thickness or thickness larger than the wiring width of, it is possible to face the coil antenna 81 of the tag detection unit 80 as closely as possible, and it is possible to retain its function even if it is cut a little, so that it can be worn. It is possible to improve the tolerance of all.

The relay cable 403 is twisted an odd number of times, and the IC inlet 220 is installed substantially parallel to the surfaces of the heads 104 and 114 of the upper punch 100 and the lower punch 110 of the rotary press machine 10. The currents flowing through the communication antennas 401 and 401a and the inlet magnetic field coupling antenna 402 are in the same direction with respect to the surfaces of the heads 104 and 114 of the upper punch 100 and the lower punch 110 of the rotary press device 10. In this case, the surfaces of the reader communication antennas 401 and 401a and the surface of the inlet magnetic field coupling antenna 402 are substantially parallel to each other, and the distance between the surfaces can be made sufficiently smaller than the value of the diameter of each antenna surface. it can.
