Description

  TECHNICAL FIELD The present invention relates to a tableting machine for producing a tablet in which an IC chip such as an IEM chip (internal tracking digital sensor) tablet is embedded.

  In recent years, tablets with IC chips in which various IC chips are embedded in tablets have been considered. This IC chip is also called a sensor chip and has a function of generating electricity and transmitting a signal in response to gastric juice, for example. By receiving this signal, it is possible to detect whether or not the patient has taken the tablet, and avoid forgetting to take the drug or taking the drug excessively. In addition, with the function built into the IC chip, for example, heart rate, respiratory rate, body position (body angle) and other important patient data are automatically collected to track the patient's health status and monitor the effects of medication. You can

  To embed such an IC chip inside a tablet, for example, the following tableting process is carried out. First, a tableting machine provided with a die comprising a plurality of vertically penetrating hole portions provided along the periphery of a disk-shaped rotary plate, and an upper punch and a lower punch that are respectively arranged above and below the plurality of die so as to be able to move up and down. To use. In this tableting machine, the upper and lower punches arranged above and below each die are rotated and moved in synchronization with the rotation of the rotary plate. Then, the following steps are sequentially executed while rotating.

  (1) Insert the lower punch into the die and put the drug powder into the die. (2) After scraping the surface of the die to remove excess drug powder, lower the lower punch a little to make a space in the die. This slightly lowered distance is a distance according to the thickness of the IC chip, for example. (3) The IC chip is supplied into the space inside the die to place the IC chip on the surface of the drug powder, and then the lower punch is further lowered. Along with this, the drug powder in the mortar moves down as a whole, and the IC chip also moves down following it. Therefore, a predetermined space is formed inside the die above the upper surface of the IC chip. (4) The drug powder is supplied again into the die, and the surface of the die is ground to remove excess drug powder. (5) The upper punch is lowered and inserted into the die, and the drug powder is compressed by the upper punch and the lower punch.

  The tableting machine described above has the following problems. That is, in the step (3), since the IC chip is dropped and supplied into the die, it is in a state of being lightly placed on the drug powder. Therefore, when the lower punch is lowered, the IC chip also descends as the drug powder descends, but at that time, the IC chip laterally moves and a positional shift easily occurs. If the tablet size is smaller than that of the IC chip, the end of the IC chip may be exposed on the tablet surface.

  In order to solve this problem, for example, it is conceivable to increase the descending distance of the lower punch performed in the stroke of (2) so that the lower punch does not move downward in the stroke of (3). However, in this case, the distance from the upper end of the die to the upper surface of the drug powder becomes long, and when the IC chip is dropped and supplied, it can be supplied to an appropriate position on the drug powder in a horizontal position. There is a risk that it will disappear, creating a new issue that a stable supply will not be possible.

Further, as (3) measures against the displacement of the IC chip due to the lowering movement of the lower punch, for example, as described in paragraph [0076] of Patent Document 1, the surface of the drug powder is made concave by the pushing portion of the positioning guide. It is possible to prevent misalignment by setting the IC chip in the recess and setting the IC chip in the recess. However, the above-mentioned structure cannot be applied to a continuously operating tableting machine. That is, in the technique disclosed in Patent Document 1, the IC chip supply device is provided with the pressing portion of the positioning guide. Therefore, when the rotary plate is rotationally moved and the die to be subjected to the step (3) reaches the supply position of the IC chip supply device, it is temporarily stopped. Then, during the temporary stop, it is necessary to move the pushing portion of the positioning guide downward to enter the mortar to form the concave portion.
Furthermore, since the inner peripheral dimension of the recess is larger than the outer peripheral dimension of the IC chip, displacement of the IC chip is restricted within the recess, but not sufficient.

  In order to solve the above-mentioned problems, the tableting machine of the present invention is (1) synchronized with rotation of a rotary plate having a plurality of dies formed of through holes arranged along the circumferential direction and rotation of the rotary plate. And revolving, and a lower punch that is inserted and arranged so as to be able to move up and down in the die from below the mortar, and an orbital movement that revolves in synchronization with the rotation of the rotating plate and an upper punch that is disposed above the mortar. A lower layer drug powder supply device for filling and supplying the drug powder into the die; an IC chip supply device for supplying an IC chip to the surface of the drug powder in the die supplied by the lower layer drug powder supply device; An upper layer drug powder supply device for filling and supplying the drug powder into the die so as to cover above the IC chip supplied by the IC chip supply device, and the IC chip has a base plane and a base plane thereof. On the other hand, it has a protrusion projecting to one side more than the other side, the upper punch is provided with an outer punch, and an intermediate punch arranged in the outer punch so as to be able to move up and down relatively, A first posture in which the lower end of the middle punch part and the lower end of the outer punch part form a continuous surface, and the middle punch part moves downward relative to the outer punch part from the first posture, It is configured such that the lower end of the punch part can take a second posture in which it projects downward from the lower end of the outer punch part, and the lower end of the middle punch part in the second posture is the lower layer chemical powder supply device. The IC chip supply device is configured so as to be located below the surface of the filled and supplied drug powder, and the IC chip supply device is provided with the middle punch part located below the surface of the drug powder. The supply is performed so that the protrusion of the IC chip is fitted into the recessed portion of the surface, and the drug in the die between the upper punch and the lower punch in the first posture. The powder was configured to be compressed.

  Since the upper punch has a double structure of the middle punch and the outer punch, and the middle punch can be moved up and down relatively to the outer punch, the first punch with the middle punch protruding downward from the outer punch By taking two positions, the lower end of the middle punch part pushes inward the surface of the drug powder filled in the die to form a recess. Since the upper punch revolves in synchronism with the rotation of the rotating plate, even when the rotating plate and thus the mortar are continuously moving, the middle punch moves up and down to enter the mortar and the surface of the drug powder. It is possible to form a recessed portion in the recess or to separate it upward from the die after formation. Then, after the formation of the recessed portion, the IC chip is supplied, the drug powder is further filled on the supplied IC chip, and then the tablet containing the IC chip is manufactured by performing usual tableting processing such as compression. can do. That is, it is possible to manufacture tablets while continuously operating without temporarily stopping the rotary plate.

Further, when the IC chip is supplied, the protrusion of the IC chip is faced down and the protrusion is fitted into the recess formed by the middle punch. After supplying the IC chip, in order to cover the upper part of the IC chip with the drug powder, the lower punch is moved downward to secure a space for supplying the drug powder above the IC chip in the die. Along with the lowering movement of the lower punch, the surface position of the drug powder and the IC chip also lower. Since the protrusion of the IC chip fits into the recess of the drug powder, the IC chip does not shift laterally during this downward movement, and the position where the drug powder is supplied to the surface can be retained. Therefore, the IC chip is finely embedded in the drug powder by the subsequent filling and supplying of the drug powder.
(2) The recess may have a size corresponding to the protrusion of the IC chip. (3) The rotating plate may be configured to rotate continuously.

  (4) In the method for producing a tablet according to the present invention, an IC chip is supplied onto the drug powder filled in the die, and then the drug powder is filled from above the IC chip to obtain these drug powders. A method of manufacturing a tablet containing an IC chip by compressing an IC chip member from above and below with an upper punch and a lower punch, wherein the IC chip has a base plane and one side of the base plane from the other side. Also has a protruding portion, the upper punch includes an outer punch portion and an intermediate punch portion that is arranged so as to be able to move up and down relatively to the outer punch portion, and the die before the IC chip is supplied. With respect to the drug powder supplied therein, the middle punch part is projected from the lower end of the outer punch part to form a recessed part on the surface of the drug powder, and the protrusion is fitted into the recessed part so as to fit the drug product. The IC chip is placed on the surface of the powder, then the chemical powder is supplied into the die to cover the IC chip, and the lower end of the middle punch part and the lower end of the outer punch part form a continuous surface. The medicine powder filled in the die was compressed between the upper and lower punches from above and below.

  According to the present invention, the displacement of the IC chip hardly occurs and continuous tableting can be performed.

It is a top view showing one suitable embodiment of the tabletting machine concerning the present invention. It is a process drawing explaining an operation.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention should not be construed as being limited to this, and various changes, modifications and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

The tableting machine of the present embodiment is for manufacturing a tablet having an IC chip built therein. The IC chip used in this embodiment will be described. The IC chip 30 has a base plane and a protrusion projecting on one side of the base plane more than the other side. Specifically, the IC chip 30 has a form in which a chip main body 32, which is a protrusion, is attached to the center position of a circular base film 31, which is a base plane, and the surface is entirely coated. The base film 31 has, for example, a disk-shaped outer diameter with a diameter of 3.5 mm, and has, for example, a function of supporting the chip body 32, an antenna function of transmitting and receiving information to and from the outside, and the like. The chip body 32 has, for example, a 1 mm square rectangular outer shape, and an electronic circuit is incorporated therein. The chip body 32 has, for example, a storage unit that stores information that identifies the tablet 35 in which the IC chip 30 is embedded, a function that transmits the information stored in the storage unit at a predetermined timing, and the like. Further, since the surface is coated, the surface shape of the protrusion does not rise steeply from the flat portion of the base film 31, but a partially smooth curved surface based on the rectangular outer shape of the chip body 32. It becomes the form which has.

  A tableting machine of the present embodiment for manufacturing a tablet having the IC chip 30 built therein includes a disk-shaped rotary plate 10 having a plurality of dies 11, a lower punch 12 arranged below each mortar 11, An upper punch 13 arranged on the upper side of each die 11 and various processing devices arranged at respective positions on the periphery of the rotary plate 10 are provided.

The rotary plate 10 is linked with a drive motor (not shown) and continuously rotates in this embodiment.
The mortars 11 are through holes that are provided along the peripheral edge of the rotary plate 10 at predetermined intervals / angles and that penetrate vertically through the rotary plate 10 as shown in FIG. The lower punch 12 is inserted from below the die 11 and is vertically movable. When the lower punch 12 is inserted into the through hole of the die 11, the die 11 has a bottom and the drug powder 15 can be filled.

  The upper punch 13 is arranged above the die 11 so as to be movable up and down. When the upper punch 13 is in the upper standby position, the lower end of the upper punch 13 is located above the upper surface of the rotary plate 10, the die 11 is released upward, and the drug powder 15 can be filled and supplied. Further, when the upper punch 13 descends and is in the operating position at the lowermost end, the lower end of the upper punch 13 enters the die 11. As a result, when the die 11 is filled with the drug powder 15, the drug powder 15 is sandwiched between the lower punch 12 and the upper punch 13 and compressed to produce a tablet.

  The lower pestle 12 and the upper pestle 13 revolve in synchronism with the rotation of the rotary plate 10, and move while maintaining a state of facing the mortar 11 forming a pair. The lower punch 12 and the upper punch 13 move up and down at appropriate positions while revolving. The control of the lifting timing and the moving distance may be performed easily and accurately by using, for example, a cam.

  Here, in this embodiment, as shown in FIGS. 2D, 2J, and 2K, the upper punch 13 is provided at the center of the cylindrical outer punch portion 16 and the outer punch portion 16. It has a double structure including a middle punch 17 that is vertically movable in a through hole. The middle punch 17 has a first posture (see FIG. 2 (j), (k), etc.) in which the lower end 17a forms a curved surface continuous with the lower end 16a of the outer punch 16, and from the first posture, the middle punch is used. The second position (refer to FIG. 2D, etc.) in which the part 17 moves downward relative to the outer punch part 16 and the lower end 17a of the middle punch part 17 projects downward from the lower end 16a of the outer punch part 16 is shown. To take. The control of the up-and-down movement of the middle punch 17 may also be performed by using the cam. For example, the upper end of the middle punch part 17 is made to project above the upper end of the outer punch part 16, and the upper end of the projecting middle punch part 17 is made to cooperate with the cam so that the appropriate position of the outer punch part 16 on the outer periphery is changed. By cooperating with the cam, the middle punch part 17 and the outer punch part 16 are moved up and down at appropriate timing while revolving, and take the first posture and the second posture at appropriate positions. Further, for example, an elastic body such as a coil spring is arranged between the middle punch part 17 and the outer punch part 16, and the middle punch part 17 is biased in a direction to move upward relative to the outer punch part 16, The first posture may be taken when there is no load from the outside, and a mechanism / function may be provided to urge the middle punch 17 downward only in the section where the second posture is taken.

  As shown in FIG. 2 (d), the middle punch part 17 in the second posture is for forming a recess 15 a on the upper surface of the drug powder 15 filled in the die 11. The recess 15a is for inserting the chip body 32 of the IC chip 30 and has an inner shape corresponding to the outer shape of the chip body 32. That is, in this embodiment, the surface shape of the protrusion is such that the chip body 32 has a rectangular shape and the surface of the IC chip 30 is coated to cover the chip body 32. The cross section is approximately the same as the plane cross section of the chip body 32 (slightly larger in consideration of the thickness of the coating) or a substantially rectangular shape including the same. As will be described later, when the IC chip 30 is supplied into the die 11, the chip body 32 is fitted into the recess 15a.

  Further, the middle punch part 17 in the first posture forms a curved surface in which the lower end 17a of the middle punch part 17 and the lower end 16a of the outer punch part 16 are continuous as described above, and functions as a normal upper punch 13, That is, it has a function of contacting the upper surface / surface of the drug powder 15 and compressing the drug powder 15 with the lower punch 12.

  Various processing devices and the like arranged at respective positions on the peripheral edge of the rotary plate 10 include a lower layer chemical powder feed shoe 21, a recess forming portion 22, an IC chip supply device 23 in order along the rotation direction of the rotary plate 10. An upper layer chemical powder feed shoe 24, a pressure roller 25, and a discharge chute 26 are arranged.

  The lower layer drug powder feed shoe 21 is a device for filling and supplying the drug powder 15 into the die 11. As shown in FIG. 2A, for example, the lower layer drug powder feed shoe 21 is provided with a cover 21a that covers the inside of the die 11 and is discharged from the hopper (not shown) in which the drug powder 15 is stored. It has a function of filling and supplying the medicine powder 15 that has been received into the die 11. For example, assuming that the cover 21a is fixedly installed, the mortar 11 also revolves along with the rotation of the rotary plate 10 and separates from the installation region of the cover. As shown in the drawing, the lower end of the vertical wall portion of the cover 21a is configured to contact the upper surface of the rotary plate 10, so that the lower end of the vertical wall portion functions as a scraper, and 2B in which the excessive drug powder 15 is removed by scraping off the powder.

  The recess forming portion 22 includes a mechanism that moves the middle punch 17 relatively downward from the outer punch 16 to bring the upper punch 13 into the second posture. The lower punch 12 and the upper punch 13 passing through the recess forming portion 22 are in a state shown in FIG. 2 (d).

  The IC chip supply device 23 is a device that places the IC chip 30 on the surface of the drug powder 15 filled and supplied in the die 11. In the present embodiment, the rectangular chip body 32 of the IC chip 30 is placed so as to be fitted into the recess 15a provided on the surface of the drug powder 15, so that, for example, in a state where the IC chip 30 is suction-held. , Should be supplied. By doing so, the chip body 32 can be properly fitted into the recess 15a, the base film 31 can be kept in a horizontal position, and the base film 31 can be placed neatly on the surface of the drug powder 15. Note that the IC chip supply device 23 does not necessarily have to adsorb, and can be sandwiched by a clamper or various conventionally used mechanisms can be used.

  The upper layer drug powder feed shoe 24 is a device for filling and supplying the drug powder 15 into the die 11 on which the IC chip 30 is placed. The upper layer drug powder feed shoe 24 is provided with a cover 24a for covering the upper part of the die 11 as shown in FIG. 2 (h), for example, and is discharged from the hopper (not shown) in which the drug powder 15 is stored. It has a function of filling and supplying the medicine powder 15 that has been received into the die 11. The drug powder 15 filled and supplied by the drug powder feed shoe 24 for the upper layer fills the IC chip 30 and becomes the drug powder 15 corresponding to the upper layer portion of the tablet.

  Similar to the lower layer drug powder feed shoe 21, assuming that the cover 24a is fixedly installed, the mortar 11 also revolves along with the rotation of the rotary plate 10, and when it is separated from the installation region of the cover 24a, the cover 24a is removed. The lower end of the vertical wall portion exerts the function of a scraper, and the surface of the die 11 is scraped to remove the excess drug powder 15, resulting in the state of FIG. 2 (i).

  The pressure roller 25 is a device for pressing the lower punch 12 and the upper punch 13 so as to approach each other, and includes a preliminary pressure roller 27 and a main pressure roller 28. The preliminary pressure roller 27 and the main pressure roller 28 sandwich the pair of upper and lower punches 13 and 12 from above and below, respectively, and apply a predetermined pressure. As a result, for example, as shown in FIG. 2 (j), the drug powder 15 filled in the die 11 is sandwiched and compressed between the upper punch 13 and the lower punch 12 in the first posture. The pressure is gradually applied to the main pressure roller 28 via the preliminary pressure roller 27, and the tablet 35 containing the IC chip 30 is manufactured.

  The discharge chute 26 constitutes a path for discharging the manufactured tablets 35. In the area where the discharge chute 26 is installed, for example, as shown in FIG. 2 (k), the upper punch 13 is located above the upper surface of the rotating plate 10, and the lower punch 12 is raised in the die 11 to The upper end is flush with the upper surface of the rotary plate 10, and the manufactured tablets 35 can be discharged to the outside of the die 11. The tablets 35 discharged to the outside of the die 11 are discharged to the outside through the discharge chute 26.

  Next, a preferred embodiment of the method for producing a tablet according to the present invention, which is the operation of the above-described tableting machine, will be described. FIG. 2 shows a mode in which one mortar 11 revolves along with the rotation of the rotating plate 10 to reach the installation section of each processing device or the like while performing a predetermined process. In addition, although the upper punch 13 is partially omitted in each drawing, it actually exists in a retracted position above the die 11 as shown in, for example, FIG.

  First, as the rotary plate 10 rotates, the mortar 11 moves in the installation section of the lower layer drug powder feed shoe 21 (see FIG. 2A). At this time, the lower pestle 12 is inserted and arranged in the die 11, and the upper end of the lower pestle 12 is at a position lower than the upper surface of the rotary plate 10 by one step. This lowering distance corresponds to the thickness of the lower half of the tablet 35. Then, the lower layer drug powder feed shoe 21 fills and supplies the drug powder 15 into the die 11 while moving in the installation section of the lower layer drug powder feed shoe 21.

  Then, when the die 11 filled with the drug powder 15 is separated from the installation section of the lower layer drug powder feed shoe 21, the lower end of the vertical wall portion of the cover 21a of the lower layer drug powder feed shoe 21 causes the upper surface of the rotating plate 10 to move. Also, the drug powder 15 overflowing upward is scraped off (see FIG. 2B).

  The lower punch 12 was lowered by a predetermined amount and filled in the mortar 11 until the mortar 11 coming out of the arrangement section of the lower layer drug powder feed shoe 21 reached the next arrangement section of the depression forming section 22. The surface of the drug powder 15 is slightly lower than the upper surface of the rotary plate 10 (see FIG. 2C).

  In this state, the die 11 reaches the depression forming portion 22, the middle punch 17 moves downward while passing through the depression forming portion 22, and the lower end 17a of the die 17 comes into contact with the center of the surface of the drug powder 15 and pushes it in. The recess 15a is formed (see FIG. 2D). Then, when the mortar 11 comes out of the recessed portion forming portion 22, the middle punch portion 17 rises and separates from the drug powder 15 (see FIG. 2 (e)). The upper pestle 13 and thus the middle pestle 17 revolve around the mortar 11 and maintain a state of being aligned with the center of the mortar 11. Therefore, it is possible to form the depression 15a at the center of the surface of the drug powder 15 while continuously operating the tableting machine. Further, the middle punch 17 that has moved upward after the formation of the depression 15a returns to the first posture in which the lower end thereof is continuous with the lower end 16a of the outer punch 16.

  Next, the mortar 11 reaches the arrangement section of the IC chip supply device 23. Then, while the die 11 is passing through the IC chip supply device 23, the IC chip supply device 23 sets the IC chip 30 in the downward posture on the drug powder 15. At this time, the rectangular chip body 32 of the IC chip 30 is fitted into the recess 15a provided on the surface of the drug powder 15 (see FIG. 2 (f)).

  The lower punch 12 is further lowered by a predetermined amount and supplied into the die 11 until the die 11 that has come out of the arrangement section of the IC chip supply device 23 reaches the next arrangement section of the upper layer drug powder feed shoe 24. The IC chip 30 is located at a position lower than the upper surface of the rotary plate 10 by one step. This falling distance is a distance corresponding to the thickness of the upper half of the tablet 35 (see FIG. 2 (g)). Then, while the mortar 11 moves in the installation section of the upper layer drug powder feed shoe 24, the upper layer drug powder feed shoe 24 fills and supplies the pill 11 with the drug powder 15. As a result, the drug powder 15 is filled above the IC chip 30 and the IC chip 30 is embedded in the drug powder 15 (see FIG. 2 (h)).

  Then, when the die 11 filled with the drug powder 15 is separated from the installation section of the upper layer drug powder feed shoe 24, the lower end of the vertical wall portion of the cover 24a of the upper layer drug powder feed shoe 24 causes the upper plate of the rotating plate 10 to move. Also, the drug powder 15 overflowing upward is scraped off (see FIG. 2 (h)).

  Next, the rotary plate 10 rotates and the mortar 11 moves in the section where the pressure roller 25 is arranged. During this movement, the upper punch 13 moves downward to compress the drug powder 15 between the upper punch 13 and the lower punch 12 (see FIG. 2 (j)). As a result, the drug powder 15 is solidified and the tablet 35 containing the IC chip is manufactured. After that, when the rotary plate 10 rotates and the die 11 reaches the discharge chute 26, the lower punch 12 further moves upward to discharge the manufactured tablet 35 (see FIG. 2 (k)).
