  An embodiment of the present invention will be described with reference to the drawings. First, an overall outline of a rotary powder compression molding machine (hereinafter referred to as “molding machine”) A in the present embodiment will be described. As shown in FIG. 1, a standing shaft 2 serving as a rotating shaft is established in a frame 1 of the molding machine A, and a turntable 3 is attached to the upper portion of the standing shaft 2 via a connecting portion.

  The turntable 3 rotates horizontally, that is, rotates around the vertical shaft 2. The turntable 3 includes a table (mortar disk) 31, an upper punch holder 32, and a lower punch holder 33. As shown in FIG. 2, the table 31 has a substantially disk shape, and a plurality of mortar holes 4 are provided at predetermined intervals along the rotation direction (circumferential direction) on the outer peripheral portion thereof. The mortar hole 4 penetrates the table 31 in the vertical direction. The table 31 may be divided into a plurality of plates. The table 31 itself is not directly formed with the mortar hole 4, but a plurality of mortar members which are separate from the table 31 and can be attached to and detached from the table 31 are attached to the table 31. It is good also as a structure which has drilled the mortar hole penetrated to the up-down direction in each.

  An upper punch 5 and a lower punch 6 are arranged above and below each mortar hole 4. The upper heel 5 and the lower heel 6 are held by the upper heel holding portion 32 and the lower heel holding portion 33 so as to be individually slidable in the vertical direction with respect to the mortar hole 4. The tip 53 of the upper arm 5 enters and exits the mortar hole 4. The tip 63 of the lower punch 6 is always inserted into the mortar hole 4. The upper iron 5 and the lower iron 6 together with the turntable 3 and the mortar hole 4 rotate horizontally, that is, revolve around the vertical shaft 2.

  A worm wheel 7 is attached to the lower end side of the vertical shaft 2. A worm gear 10 meshes with the worm wheel 7. The worm gear 10 is fixed to a gear shaft 9 that is driven by a motor 8. The driving force output from the motor 8 is transmitted to the gear shaft 9 by the belt 11, and rotationally drives the vertical shaft 2, and thus the rotating disk 3 and the eaves 5 and 6 via the worm gear 10 and the worm wheel 7.

  The compression-molded product P, for example, a powder as a raw material such as a pharmaceutical tablet is filled into the mortar hole 4 from the feed shoe X. The types of the feed shoe X include a stirring feed shoe and an open feed shoe, any of which may be adopted. A powder supply device is used to supply the powder to the feed shoe X. Supply of the powder with respect to the powder supply apparatus is performed from the hopper 19. The hopper 19 can be attached to and detached from the molding machine A.

  As shown in FIGS. 2 and 3, a preload upper roll 12 and a preload lower roll which are paired up and down on the revolving track around the vertical shaft 2 of the eaves 5 and 6 so as to sandwich the eaves 5 and 6. 13, there are a main roll 14 and a main roll 15. The pre-loading roll 12 and the pre-loading roll 13, and the main-pressing roll 14 and the main-pressing roll 15 are arranged so as to compress the powder filled in the mortar hole 4 from above and below with the tip surfaces of the tips 53 and 63. The two cages 5 and 6 are urged in a direction in which they approach each other.

  The upper collar 5 and the lower collar 6 have head parts 51 and 61 pressed by the rolls 12, 13, 14, and 15, respectively, and body parts 52 and 62 having a smaller diameter than the head parts 51 and 61. The upper heel holding portion 32 of the turntable 3 holds the body portion 52 of the upper heel 5 so as to be slidable up and down, and the lower heel holding portion 33 holds the body portion 62 of the lower heel 6 so as to be slidable up and down. To do. The distal end portions 53 and 63 of the trunk portions 52 and 62 are thinner than other portions so as to be inserted into the mortar hole 4 and have a diameter substantially equal to the inner diameter of the mortar hole 4. The rolls 12, 13, 14, and 15 approach the heads 51 and 61 of the saddles 5 and 6 due to the revolution of the saddles 5 and 6, and come into contact with the heads 51 and 61. Furthermore, the rolls 12, 13, 14, and 15 push the upper collar 5 downward and push the lower collar 6 upward. During the period when the rolls 12, 13, 14, 15 are in contact with the flat surfaces on the ridges 5, 6, the ridges 5, 6 continue to apply a certain pressure to the powder in the mortar 4.

  A molded product take-out position 16 exists at a position advanced from the pressurization position by the main roll 14 and the main roll 15 along the rotation direction of the rotary plate 3 and the eaves 5 and 6. At the molded product take-out position 16, the lower punch 6 is raised until the upper end surface of the tip 63 of the lower punch 6 becomes substantially the same height as the upper end of the die hole 4, that is, the upper surface of the table 31. P is pushed out of the mortar 4. The molded product P pushed out from the mortar hole 4 is collected by the following molded product take-out device.

  Hereinafter, the molded product take-out device (hereinafter referred to as “take-out device”) B of the present embodiment attached to the molding machine A will be described in detail. As shown in FIGS. 4 to 6, the take-out apparatus B takes out the molded product P molded by the molding machine A at the molded product take-out position 16 and conveys it toward the molded product collection unit 21. . This take-out apparatus B has a pocket hole 171 for capturing the molded product P, and is located directly below the rotary member 17 that rotates horizontally in synchronization with the table 31 of the molding machine A and the locus of horizontal rotation of the pocket hole 171. The support member 18 for supporting the molded product P captured in the pocket hole 171 from below, and the rejection for selectively removing the defective molded product P or the molded product P to be sampled in the middle of the conveying path. The mechanism 182 is a main component.

  The rotating member 17 is a disc-shaped member provided with a plurality of pocket holes 171 at predetermined intervals along the rotation direction (circumferential direction) on the outer peripheral edge portion thereof. As shown in FIG. 5, the pocket hole 171 opens at least downward, and also opens upward in this embodiment. In other words, the pocket hole 171 penetrates the rotating member 17 in the vertical direction. The rotating member 17 is arranged so that a part thereof overlaps the table 31 of the molding machine A from above. The lower surface of the part of the rotating member 17 is close to the upper surface of the table 31. The pocket hole 171 overlaps with the mortar hole 4 of the table 31 in plan view in the middle of the rotation trajectory.

  The pocket hole 171 is a long hole with a closed periphery that is expanded along the radial direction of the rotating member 17, that is, the direction orthogonal to the rotating direction. The inner dimension along the radial direction of the pocket hole 171 is larger than the inner diameter of the mortar hole 4 of the molding machine A and consequently larger than the outer diameter of the molded product P. The inner dimension along the rotational direction of the pocket hole 171 is also slightly larger than the inner diameter of the mortar hole 4 but is smaller than the inner dimension along the radial direction of the pocket hole 171. With the synchronous rotation of the table 31 and the rotating member 17, each mortar hole 4 and each pocket hole 171 temporarily overlap at the molded product extraction position 16. At this time, the mortar hole 4 is displaced along the radial direction of the rotating member 17 relative to the pocket hole 171. However, the mortar hole 4 is expanded by the amount of expansion of the pocket hole 171 along the radial direction. The length of the overlapping period extends so as to fit in the pocket hole 171 in plan view.

  As already described, at the molded product takeout position 16, the lower punch 6 of the molding machine A rises to push the molded product P out of the mortar hole 4. At this time, the overlapping mortar hole 4 and the pocket hole 171 face each other vertically, and the molded product P pushed up from the mortar hole 4 to the height of the upper surface of the table 31 is placed in the pocket hole 171 as shown in FIG. Get in. The molded articles P are stored one by one in each pocket hole 171. As a result, in order of the mortar holes 4 of the table 31 of the molding machine A, in other words, without destroying the order of compression molding of the molded products P in the molding machine A, the molded products P are sequentially placed in the pocket holes 171 one by one. Can be accommodated side by side. Thereafter, with the rotation of the table 31 and the rotating member 17, the mortar hole 4 and the pocket hole 171 are separated from each other, and the molded product P scraped to the pocket hole 171 is separated from the table 31 together with the pocket hole 171. The transition is made directly above the support member 18. The molded product P in the pocket hole 171 is supported by the support member 18.

  The outer edge of the pocket hole 171, that is, the edge near the outer peripheral edge of the rotating member 17 is closed, and the edge has a non-arc shape in plan view, specifically, an angle shape. The molded product P captured in the pocket hole 171 is subjected to the action of centrifugal force by the rotation of the rotating member 17 and is displaced from the inner side to the outer side in the pocket hole 171. However, the molded product P abuts on the outer edge of the pocket hole 171 and is prevented from further displacement, and does not protrude outward from the pocket hole 171. In a state where the molded product P is in contact with the outer edge of the pocket hole 171, a slight gap is generated between the molded product P and the outer edge of the pocket hole 171.

  The support member 18 that supports the molded product P in the pocket hole 171 from below is disposed so as to overlap most of the rotating member 17 from below. As shown in FIG. 6, the upper surface of the support member 18 is close to the lower surface of the rotating member 17. That is, the height position of the support member 18 is equal to the height position of the table 31 of the molding machine A. Therefore, in order to avoid interference with the table 31, a portion of the support member 18 corresponding to the molded product extraction position 16 where the table 31 and the rotating member 17 overlap in plan view is cut out. The edge of the part of the support member 18 is close to the outer peripheral edge of the table 31, and when the pocket hole 171 that has captured the molded product P is detached from directly above the table 31, the molded product P is reliably supported, Dropping from the pocket hole 171 is prevented.

  A cover 20 that closes the pocket hole 171 from above is provided immediately above the rotating member 17. Due to the presence of the cover 20, it is possible to prevent the molded product P captured in the pocket hole 171 from unexpectedly jumping out of the pocket hole 171. The cover 20 may be fixed to the rotating member 17 or integrated with the rotating member 17, or may not be fixed to the rotating member 17. In the former case, the cover 20 rotates integrally with the rotating member 17, but in the latter case, the cover 20 does not necessarily rotate even if the rotating member 17 rotates.

  In the present embodiment, the molded product collection unit 21 serving as the terminal position for transferring the molded product P is set at a symmetrical position with respect to the molded product take-out position 16 and the rotation center of the rotating member 17. The molded product P captured in the pocket hole 171 of the rotating member 17 at the molded product take-out position 16 is usually conveyed to the molded product collection unit 21. However, there is a desire to selectively remove or collect a specific molded product P, for example, a defective product or a sampled product from the molded product P group that is transferred to the molded product collection unit 21.

  Therefore, a drop port 181 for dropping a specific molded product P is opened at a position in the middle of the locus of rotation of the pocket hole 171 from the molded product take-out position 16 to the molded product collection unit 21 in the support member 18. ing. The drop port 181 overlaps with a portion that is biased inward from the outer edge of the pocket hole 171 in plan view, but does not overlap with the outer edge of the pocket hole 171.

  In addition, the exclusion mechanism 182 drops the molded product P into the drop port 181 by inducing a displacement of the molded product P from the outside toward the inside in the pocket hole 171. The exclusion mechanism 182 in the present embodiment mainly includes an air injection nozzle that blows air having a pressure higher than atmospheric pressure into the gap between the molded product P in the pocket hole 171 and the outer edge of the pocket hole 171. As shown in FIG. 6, the rotating member 17 opens on the outer surface of the rotating member 17 and communicates the outside of the rotating member 17 and the inside of the pocket hole 171 (the outer edge of the pocket hole 171). An air inlet 172 for staking is preliminarily drilled. Of course, the inner diameter of the air inlet 172 is smaller than the inner diameter of the mortar hole 4, that is, the outer diameter of the molded product P. The air injection nozzle 182 faces the outer surface of the rotating member 17 and is disposed at a position on a straight line connecting the rotation center of the rotating member 17 and the drop port 181.

  If positive air is injected from the air injection nozzle 182 when the pocket hole 171 that has captured the specific molded product P to be excluded or recovered passes in the vicinity of the air injection nozzle 182, the air is injected into the air. The molded product P is blown into the gap between the molded product P in the pocket hole 171 and the outer edge of the pocket hole 171 through the inlet 172, and the molded product P is moved from the outer side of the pocket hole 171 to the inner side by the air pressure. Displace. As a result, the molded product P falls to the drop port 181 established in the support member 18. The molded product P that has fallen into the dropping port 181 cannot arrive at the molded product collection unit 21.

  On the other hand, in the pocket hole 171 where the air was not blown, the molded product P receiving the action of the centrifugal force is located on the outer side of the pocket hole 171, and (the dropping port 181 may be given up. Also, most or all of the molded product P does not pass directly above the drop port 181, and the molded product P does not fall into the drop port 181. The molded product P that has not fallen into the drop port 181 eventually arrives at the molded product collection unit 21.

  The control device (not shown) of the molding machine A in this embodiment is used when filling the powder into the mortar hole 4 or compressing the powder filled in the mortar hole 4 with the ridges 5 and 6. Pressure or the like is detected via various detectors, and the quality of the molded product P molded in each mortar hole 4 is individually determined. Since a specific method for the determination can be that of a known molding machine A, the description is omitted here. Therefore, in order to eliminate the molded product P determined to be a defective product, the control device causes the air injection nozzle 182 to air the timing when the pocket hole 171 that has captured the defective molded product P passes near the air injection nozzle 182. Is operated to open and close a valve that controls the flow of air (not shown. The valve may be built in the air injection nozzle 182).

  As will be described later, a portion of the support member 18 corresponding to the molded product collection unit 21 is cut away. Thereby, in the molded product collection | recovery part 21, the pocket hole 171 and the supporting member 18 of the rotating member 17 do not overlap by planar view. Accordingly, the molded product P captured by the pocket hole 171 of the rotating member 17 and transferred to the molded product recovery unit 21 eventually loses support from the lower side by the support member 18 and falls off from the pocket hole 171. .

  As shown in FIG. 4, a molded product collection device (hereinafter referred to as “collection device”) C can be installed in the molded product collection unit 21 separately from the molded product take-out device B. The recovery device C has a recovery hole 221 that captures the molded product P, and rotates horizontally in synchronization with the table 31 of the molding machine A and the rotation member 17 of the take-out device B, and the horizontal direction of the recovery hole 221. And a support member 23 that supports the molded product P directly below the rotation locus and captured in the recovery hole 221 from below.

  The rotating member 22 is a disk-shaped member having a plurality of collection holes 221 provided at predetermined intervals along the rotation direction (circumferential direction) on the outer peripheral edge thereof. The recovery hole 221 opens at least upward, and also opens downward in this embodiment. In other words, the recovery hole 221 penetrates the rotating member 22 in the vertical direction. The rotating member 22 of the collection device C is arranged so that a part thereof overlaps the rotating member 17 of the take-out device B from below. The upper surface of the part of the rotating member 22 is close to the lower surface of the rotating member 17 of the take-out device B. And the collection | recovery hole 221 overlaps with the edge part of the outer side of the pocket hole 171 of the rotation member 17 of the extraction apparatus B in planar view in the middle of the locus | trajectory of the rotation.

  The recovery hole 221 is a hole having a closed periphery that is slightly expanded along the radial direction of the rotating member 22, that is, the direction orthogonal to the rotational direction. The inner dimension along the radial direction of the recovery hole 221 is larger than the inner diameter of the mortar hole 4 of the molding machine A, but smaller than the inner dimension along the radial direction of the pocket hole 171. The inner dimension along the rotation direction of the recovery hole 221 is also slightly larger than the inner diameter of the mortar hole 4, but is smaller than the inner dimension along the radial direction of the recovery hole 221. As the rotating member 17 and the rotating member 22 rotate synchronously, the pocket holes 171 and the recovery holes 221 temporarily overlap in the molded product recovery part 21. At this time, the recovery hole 221 is displaced along the radial direction of the rotating member 17 relative to the pocket hole 171. However, the recovery hole 221 is increased by the amount of expansion of the pocket hole 171 along the radial direction. The length of the overlapping period extends so as to fit in the pocket hole 171 in plan view.

  As already described, the support member 18 does not exist in the molded product collection unit 21, and the molded product P that has reached the molded product collection unit 21 falls from the pocket hole 171. At this time, the overlapping pocket hole 171 and the collection hole 221 are opposed to each other in the vertical direction, and the molded product P dropped from the pocket hole 171 is caught in the collection hole 221. The molded products P are stored one by one in each collection hole 221. As a result, in order of the pocket holes 171 of the take-out device B, in other words, the order in which the take-out device B takes out the molded products P from the molding machine A is not changed, and the molded products P are sequentially placed in the respective collection holes 221 one by one. Can be accommodated side by side. Thereafter, as the rotating member 17 and the rotating member 22 rotate, the pocket hole 171 and the recovery hole 221 are separated from each other, and the molded product P that has dropped into the recovery hole 221 is lowered from below by the support member 23 of the recovery device C. While being supported, it rotates together with the rotating member 22 and the recovery hole 221.

  In addition, the space | interval where the some collection | recovery hole 221 is located in a line with the rotation direction on the rotation member 22 of the collection | recovery apparatus C is the number of the pocket holes 171 lined up along the rotation direction on the rotation member 17 of the extraction apparatus B. It is narrower than the interval. Therefore, the rotation speed (angular velocity) of the rotation member 22 of the recovery device C is slower than that of the rotation member 17 of the take-out device B. In the illustrated example, adjacent recovery holes 221 in the rotating member 22 are joined so as to communicate with each other.

  The outer edge of the recovery hole 221, that is, the edge close to the outer peripheral edge of the rotating member 22 is closed, and the edge has a non-arc shape in plan view, specifically an angle shape. The molded product P captured in the recovery hole 221 is subjected to the action of centrifugal force by the rotation of the rotating member 22 and is displaced from the inner side to the outer side in the recovery hole 221. However, the molded product P abuts on the outer edge of the recovery hole 221 and is prevented from further displacement, and does not jump out of the recovery hole 221 outward.

  In the recovery device C, the support member 23 that supports the molded product P in the recovery hole 221 from below is disposed so as to overlap most of the rotating member 22 from below. The upper surface of the support member 23 is close to the lower surface of the rotating member 22.

  The height position of the rotation member 22 of the collection device C is equal to the height position of the support member 18 of the extraction device B. Therefore, in order to avoid interference between the rotation member 22 (and also the support member 23) of the recovery device C and the support member 18 of the extraction device B, the rotation of the rotation member 17 of the extraction device B and the recovery device C in the support member 18 is performed. The part corresponding to the molded product collection | recovery part 21 with which the member 22 overlaps planarly is notched. The edge of the part of the support member 18 of the take-out device B is close to the outer peripheral edge of the rotation member 22 of the recovery device C. In the molded product collection unit 21, the pocket hole 171 of the rotating member 17 of the take-out device B is detached from immediately above the support member 18, but immediately after that, the pocket hole 171 transitions directly above the rotating member 22 of the collecting device C. Thus, the molded product P in the pocket hole 171 is reliably supported by the rotating member 22 of the recovery device C, and does not fall to a place other than the recovery hole 221.

  In this embodiment, the table 31 is provided with the mortar hole 4 penetrating vertically, and the upper and lower ridges 5 and 6 are held above and below the mortar hole 4 so as to be slidable up and down. The molded product take-out device attached to the rotary powder compression molding machine A in which both the powder rotates horizontally and the powder filled in the mortar hole 4 is compressed by the upper punch 5 and the lower punch 6 to form the molded product P. B, which is horizontally rotatable and is disposed on the rotating member 17 so as to partially overlap the table 31 from above. The rotating member 17 is provided along the radial direction of the rotating member 17. The outer edge of the hole 4 is larger than the inner diameter of the hole 4, and the outer edge of the hole 4 is closed. The molded article P pushed up from the mortar hole 4 by the lower punch 6 when passing directly above the table 31 is received. The pocket hole 171 to be captured and the pocket hole 171 horizontal In the right under the rotation of the trajectory, to constitute a product removal device B comprising a support member 18 for supporting the molded article P trapped in the pocket hole 171 from below.

  According to the present embodiment, unlike the conventional take-out device B, there is no need to provide a guide facing the outer peripheral edge of the rotating member that scrapes and conveys the molded product P, and the take-out device B that has a simple configuration and is easy to maintain. Can be realized at low cost. Further, the rotating member 17 takes out a plurality of molded products P taken out from the molding machine A one by one in the order in which the mortar holes 4 are arranged in the molding machine A, that is, in the order in which the molded products P are molded, without breaking the order. The pocket hole 171 can be aligned and stored.

  Further, a drop port 181 that is opened so as to overlap with a portion that is biased inward from the outer edge of the pocket hole 171 in the support member 18, and the outer side of the molded product P in the pocket hole 171. Since a displacement mechanism 182 for dropping the molded product P into the dropping port 181 by inducing a displacement from the inside to the inside is provided, only the required molded product P is used for the purpose of eliminating defective products and sampling. Can be selectively dropped into the drop port 181 to be removed or extracted.

  Since the exclusion mechanism 182 blows air into the pocket hole 171, it can be easily mounted on the take-out device B.

  Since the cover 20 is closed above the pocket hole 171, it is possible to reliably prevent the molded product P from jumping out of the pocket hole 171 in the process of conveyance.

  In addition, at the end position of the transfer of the molded product P captured in the pocket hole 171 by the rotating member 17, the part is provided so as to overlap the part outside the pocket hole 171, and the part where the support member 18 does not exist. Since a certain molded product recovery unit 21 is provided and the molded product P that has reached the end position is configured to fall from the pocket hole 171 to the molded product recovery unit 21, it is captured in the pocket hole 171. In this state, the molded product P transferred by the rotating member 17 can be appropriately recovered in the molded product recovery unit 21.

  The present invention is not limited to the embodiment described in detail above. In the above-described embodiment, air is blown into the pocket hole 171 of the rotating member 17 of the take-out device B from the outside toward the inside, thereby displacing the molded product P in the pocket hole 171 to the inside and the drop port 181. I was trying to drop it into. However, the mode of the exclusion mechanism for selectively eliminating the specific molded product P is not limited to this. For example, as shown in FIG. 7, a lower part of the pocket hole 171 is provided as an exclusion mechanism in the middle of the locus of rotation of the pocket hole 171 from the molded product take-out position 16 to the molded product collection unit 21 in the support member 18. The air injection nozzle 24 for injecting air upward from the air injection nozzle 24 is installed, and the cover 20 at the position above the air injection nozzle 24 is cut or removed, and the pocket hole 171 is opened upward at the position. So that The cover 20 is not fixed to the rotating member 17 or integrated with the rotating member 17, and does not rotate horizontally with the rotating member 17 and does not move. Then, air is ejected from the air injection nozzle 24 at a timing when the pocket hole 171 that has captured the molded product P to be excluded passes immediately above the air injection nozzle, so that the target molded product P is moved upward from the pocket hole 171. Blow up and fly. The skipped molded product P cannot arrive at the molded product recovery unit 21.

  Instead of the air injection nozzle 24 described above, a drive member (not shown) capable of moving back and forth between a position below and above the lower surface of the rotating member 17 is provided, and the molded product P to be excluded It is also possible to raise the drive member at the timing when the pocket hole 171 that has captured the above passes directly above the drive member to push up the molded product P in the pocket hole 171 from below and to fly out of the pocket hole 171. It is done.

  Further, the outer edge of the pocket hole 171 of the rotating member 17 does not have to be completely closed as long as the outer edge of the pocket hole 171 is narrowed so as not to open beyond the outer diameter of the molded product P. Good. In other words, a gap that is narrower than the outer diameter of the molded product P may be opened at the outer edge of the pocket hole 171. The air inlet 172 in the above embodiment can also be understood as a kind of such a gap.

  As shown in FIG. 8 or FIG. 12, the shape of the pocket hole 171 provided in the rotating member 17 of the take-out device B may be formed in a substantially triangular shape in plan view. More specifically, the pocket hole 171 in the illustrated example is positioned at a position where one of its apexes faces the outer peripheral edge of the rotating member 17, and from there toward the inside along the radial direction of the rotating member 17, It has a substantially isosceles triangular periphery so that the inner dimension along the rotation direction of the rotating member 17 gradually expands. The inner dimension along the radial direction of the pocket hole 171 is larger than the inner diameter of the mortar hole 4 of the molding machine A and consequently larger than the outer diameter of the molded product P. The inner dimension along the rotation direction of the pocket hole 171 is larger than the inner diameter of the mortar hole 4 except for the apex portion closest to the outer peripheral edge of the rotation member 17, but is along the radial direction of the pocket hole 171. It is smaller than the inner size. The corners of the peripheral edge of the pocket hole 171, that is, the portions corresponding to the apexes of the triangle are rounded. The process of forming the pocket hole 171 having such a shape in the rotating member 17 is easy. Of course, the shape of the peripheral edge of the pocket hole 171 is not limited to those illustrated in FIG. 4, FIG. 8, or FIG. 12, and a shape different from these is allowed.

  As shown in FIGS. 8 to 11, a dust collecting duct 25 is attached to the rotating member 17 for sucking and removing powder and other dusts that have entered the pocket hole 171 of the rotating member 17 from the pocket hole 171. You can also. The dust collecting duct 25 in the illustrated example is located above the outer peripheral edge of the rotating member 17 in which the pocket hole 171 is formed, and is opened downward. The dust collection duct 25 is connected to a dust collector (not shown) that generates negative pressure to suck and collect dust, and sucks dust remaining in the pocket hole 171 from the pocket hole 171 and guides it to the dust collector. be able to. The dust collecting duct 25 is fixed along the rotational direction of the rotary member 17 from at least the molded product take-out position 16 where the mortar hole 4 of the table 31 of the molding machine A and the pocket hole 171 of the rotary member 17 of the take-out device B overlap. In the vicinity of the horizontal rotation trajectory of the pocket hole 171, the dust in the pocket hole 171 is sucked within the range.

  However, a cover 20 that closes the pocket hole 171 from above is interposed between the rotating member 17 and the dust collection duct 25. Therefore, it is necessary to previously drill the communication holes 201 and 202 that allow the inside of the pocket hole 171 and the space above the cover 20 to communicate with each other.

  When the cover 20 is fixed to the rotating member 17 or integrated with the rotating member 17 and the rotating member 17 and the cover 20 rotate integrally, as shown in FIGS. 9 and 10, In the cover 20, a small hole 201 that penetrates the cover 20 up and down is provided at a location immediately above each pocket hole 171. The inner diameter of each small hole 201 is set to be smaller than the outer diameter of the molded product P so that the molded product P captured in the pocket hole 171 does not jump out of the rotating member 17 through the small hole 201. It is set smaller than the thickness dimension of the product P (the distance between the tip surface of the tip 53 of the upper collar 5 and the tip surface of the tip 63 of the lower collar 6 when the molded product P is compression-molded).

  On the other hand, when the cover 20 is not fixed to the rotating member 17 and the cover 20 does not rotate together with the rotating member 17, as shown in FIG. 11, immediately above the locus of horizontal rotation of the pocket hole 171. A slot 202 having a partial arc shape extending through the cover 20 in the vertical direction and extending along the rotation direction of the rotary member 17 in plan view is formed. In order to prevent the molded product P captured in the pocket hole 171 from jumping out of the rotary member 17 through the slot 202, the width dimension along the radial direction of the rotary member 17 of each slot 202 is outside the molded product P. It is set smaller than the diameter, preferably smaller than the thickness dimension of the molded product P.

  In the period immediately after the operation of the molding machine A is started, the powder is not necessarily compressed sufficiently and the molded product P having the desired hardness and outer shape cannot be obtained. That is, it means that there is a concern that powder that is not sufficiently compressed is generated in the mortar hole 4 and that the powder enters the pocket hole 171 of the take-out device B as useless dust. By attaching the dust collecting duct 25 as described above, dust can be sucked and removed from the pocket hole 171, and the dust is between the rotating member 17 and the table 31, and between the rotating member 17 and the supporting member. 18 or between the rotating member 17 and the rotating member 22 can be prevented. Then, it is avoided that the dust hinders the rotation of the table 31, the rotation member 17, or the rotation member 22, and the rotation of the rotation of the table 31, the rotation member 17, and the rotation member 22 is lost (the phase of rotation). ) Will not cause problems.

  The dust collection duct 25 also functions effectively for removing dust adhering to the surface of the finished molded product P.

  As shown in FIG. 12, an analyzer for analyzing the molded product P captured in the pocket hole 171 on the transport path from the molded product take-out position 16 to the molded product collection unit 21 in the take-out device B, the molded product. You may install apparatus 26, such as an inspection apparatus for inspecting the quality of P, and a processing apparatus for performing some post-processing on the molded product P.

  As specific examples of the analysis device or the inspection device 26, the molded product P is photographed by a camera sensor, the photographed image is analyzed to determine whether the molded product P is good or defective, or the weight of the molded product P is measured. To determine whether the molded product P is good or defective, and the components contained in the molded product P are analyzed by Raman spectroscopy, near infrared spectroscopy (NIR or near infrared absorption spectrum method), X-ray diffraction, X-ray transmission measurement And a metal detector for detecting whether or not the molded product P is good / bad by analyzing by high performance liquid chromatography (HPLC) or the like, and a metal detector for detecting the mixing of metal sides into the molded product P.

  Examples of the processing apparatus 26 include a laser processing machine that engraves or laser marks the surface of the molded product P by irradiating the molded product P, an ink jet printer that performs printing on the surface of the molded product P, and the like. It is also conceivable to perform laser engraving, laser marking or printing only on the good molded product P or defective molded product P.

  In addition, as shown in FIG. 12, the defective molded product P or the molded product P to be sampled is placed in the middle of the conveyance path downstream of the device 26 and upstream of the molded product recovery unit 21 in the take-out device B. An exclusion mechanism 182 and a drop port 181 for selectively eliminating and collecting can also be disposed.

  In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
