Description

  The present invention relates to a packaging device that divides a supplied granular material by a predetermined amount.

  Conventionally, what is shown in the following patent document 1 is proposed as a packaging apparatus for packaging powder bodies, such as a chemical | medical agent (powder). This packaging device scrapes (cuts out) the granular material supplied along the annular mounting portion (annular concave groove) on the rotary table toward the radially outer side of the rotary table by a predetermined area. It has a cut-out part. The cut-out part is configured to rotate around the center of curvature (around the horizontal axis) of the groove bottom of the annular groove to cut out the powder on the groove bottom of the annular groove, The cutout plate and the cutout plate (on the basis of the rotation direction of the rotary table at the time of cutting (hereinafter the same)) are integrated with the cutout plate. It has a damming part (damming plate) that rotates around the center of curvature and dams up the granular material. In this packaging device, the cut-out portion is rotated around the center of curvature of the groove bottom while the rotary table is intermittently rotated about the vertical axis every equal circumferential length. Thus, the powder particles are packaged into a plurality of packages so as to cut out the powder particles on the annular concave groove with the cutting plate in the radial direction of the rotary table while blocking the powder particles with the blocking plate.

  In other words, in this packaging device, after the powder material that has been evenly supplied to the annular groove is cut out from the powder that is to be packaged (first time) with the cutting plate as the first package, the rotary table has a predetermined circumference. Rotate the direction length. Thereafter, the powder that is packaged as the second package is cut out, and the rotary table is rotated by the same circumferential length as the first package. The cutting of the powder by the cutting plate and the rotation of the rotary table are repeated until the cutting of the powder to be packaged last. By repeating this, the powder for the entire circumference on the annular groove is cut out.

  The granular material is supplied over the entire circumference of the annular groove by a feeder or the like. The damming portion (damming plate) is in contact with the granular material on the annular groove in both the upstream and downstream portions before starting the cutting of the granular material. When the cutting of the granular material is started in this state, the granular material is cut out by the cutting plate located on the upstream side of the barrier plate.

  At this time, the blocking plate also rotates in the same direction as the cutout plate. For this reason, the granular material that has been in contact with the downstream portion (downstream side surface) of the dam plate is guided to the rotation of the dam plate by the frictional force acting on the dam plate and the granular material. Jump out of. The protruding granular material is packaged together with the granular material cut out by the cutting plate. In this case, since the sachet packaged first contains more granular material than the prescribed amount, it is not desirable. Contrary to the above, with respect to the sachet near the end of the sachet, such as the sachet that was last sachet, there is a tendency that the amount of the granulated powder that is smaller than the prescribed amount will be included. is there.

  The above phenomenon occurs when the amount of supplied granular material is large (because many granular materials are in contact with the downstream portion of the damming plate), and when the number of packages indicated by the operator or the like is large on the packaging device ( When the amount of intermittent rotation of the turntable in one cutting is reduced and it is difficult to separate the granular material from the downstream part of the weir plate), when supplying granular material such as granules (annular) The “peaks” of the granular material on the concave groove are likely to collapse, and the granular material is prone to occur “at the downstream side of the weir plate”.

JP 2009-67434 A

  Therefore, the present invention suppresses the granular material that has been in contact with the downstream portion of the damming portion from being guided by the rotation when the damming portion is rotated, and jumping out of the annular mounting portion. It is an object of the present invention to provide a packaging device capable of packaging in quantities.

  The present invention relates to a packaging apparatus that separates a plurality of packages by a predetermined amount by cutting a supplied granular material, a table having an annular mounting portion on which powder particles can be arranged, and the annular mounting portion A cutting mechanism for cutting out the granular material supplied over the entire circumference by a predetermined area along the circumferential direction of the table in the radial direction of the table, and the operation of the table and the cutting mechanism The table and the cutting mechanism, one of which rotates relative to the other around the vertical axis, and the cutting mechanism moves the annular mounting portion in the radial direction. A cutting portion for moving and cutting the powder by traversing, and the cutting portion based on the moving direction of the table as seen from the cutting mechanism with the relative rotation at the time of cutting. A damming portion located on the downstream side, and the control unit includes the damming portion as the annular mounting portion. The annular mounting is performed by moving the cutout portion in the radial direction while intermittently rotating one of the table and the cutout mechanism relative to the other in one direction. The granular material is cut out from the placing portion, and further, the control unit is configured to remove the damming portion before the first cutting is performed after the granular material is supplied over the entire circumference of the annular placing portion. After making contact with the annular mounting portion, by rotating one of the table and the cutting mechanism relative to the other in the opposite direction to the cutting, Part of the granular material is moved to the downstream side on the annular mounting portion by the damming portion.

  According to the above configuration, the control unit is configured to switch one of the table and the cutting mechanism before the first cutting is performed after the granular material is supplied over the entire circumference of the annular mounting unit. By rotating relative to the other side in the direction opposite to the direction of the cutting, a part of the granular material to be cut last is partly placed on the annular mounting portion on the downstream side by the damming portion. Move to the side. Therefore, due to the relative rotation in the reverse direction, there is a gap between the end portion near the damming portion (the end of the “mountain”) and the damming portion of the powder that is finally cut out. It can be in a state in which the contact amount of the granular material to the damming portion is reduced.

  Further, the annular mounting portion is a concave groove having a bottom surface formed in a circular arc shape that protrudes downward with the center of curvature as the center, and the damming portion has a curvature of the outer periphery that is the curvature of the bottom surface. It is a substantially disk shape, can be rotated around the horizontal axis along the circumferential direction of the annular mounting portion, and includes a ring body formed of a soft material on the outer peripheral portion, this damming portion, When rotating one of the table and the cutting mechanism relative to the other in the opposite direction, the ring body rotates around the horizontal axis while contacting the bottom surface of the annular mounting portion. Instead, at the time of the cutting, the ring body may be configured to rotate around the horizontal axis while being in contact with the bottom surface of the annular mounting portion.

  According to the above configuration, when the damming portion rotates one of the table and the cutting mechanism relative to the other in the opposite direction, the ring body is placed on the bottom surface of the annular mounting portion. While contacting, it does not rotate around the horizontal axis, and at the time of cutting, the ring body rotates around the horizontal axis while contacting the bottom surface of the annular mounting portion. For this reason, since the said damming part contacts the bottom face of the said annular mounting part, rotating around the said horizontal axis, the contact position of the damming part with respect to the said bottom face changes every moment. Therefore, it is possible to suppress vibration (chatter) caused by the ring body formed of a soft material being dragged in one direction by the relative rotation of the table and the cutting mechanism, and the generation of noise associated therewith.

  According to the present invention, a gap between the end portion near the damming portion (the end of the “mountain”) and the damming portion of the powder that is finally cut by the relative rotation in the reverse direction is provided. Or a state in which the amount of contact of the granular material with the damming portion is reduced. For this reason, when the granular material is cut out by the cutting mechanism, the granular material that has been in contact with the downstream portion of the damming portion is guided to the rotation when the damming portion rotates and is annularly mounted. Jumping out of the placement unit can be suppressed. Therefore, it is possible to wrap a predetermined amount of the granular material in the first packaged package. In addition, a sachet that is close to the end of the sachet, such as a sachet that was last sachet, can wrap a granular material in a prescribed amount. As a result, it is possible to suppress the granular material that has been in contact with the downstream portion of the damming portion from being guided by the rotation when the damming portion is rotated and jumping out of the annular mounting portion. Can be packaged.

The spacers 46 and 47 are extended to both end surfaces of the cut-out plate body 29 with a uniform width along this. That is, this extended thickness B2 in the width direction is substantially equal to the thickness of the portion of the elastic blade 45 protruding on both sides in the width direction of the tip plate portion 48.

  A plurality of round holes 50 a are formed on the plate surface of the base end plate portion 50. In addition, parallel retaining protrusions 52 spaced apart from each other by a predetermined distance are fixed to the plate surface of the base end plate portion 50 (for example, by heat fusion). The thickness of the retaining protrusion 52 is equal to the thickness of the covering portion 53. The cross-sectional shape of the retaining protrusion 52 is formed in a hemispherical shape, and is formed so as to be continuous with the covering portion 53 via a sheet portion 31 a having an extremely thin thickness as compared with the covering portion 53.

  The mounting support 54 is also a member for mounting the cutout plate 31, and is formed in a substantially cylindrical shape with the downstream side opened and the upstream side sealed.

The cover body 31A is formed in a substantially elliptical shape when viewed from the front. The curvatures of the curved portions on both sides in the radial direction are set so as to substantially match the curvature of the groove bottom surface 10, and the pin 41 is inserted through the pin hole 58 formed on the plate surface of the cover body 31A on the base end side. Thus, it is attached to the upstream side wall 54b of the attachment support 54 in an overlapping manner.

  Rotation transmission holes 61a, 61b, 61c through which the rotation transmission shaft 60 is inserted are formed at the centers of the rotating body 35, the mounting support 54, and the cover body 31A, respectively. The rotation transmission holes 61a, 61b are formed. , 61c, a rotation transmission shaft 60 is fitted inside.

  The tip of the rotation transmission shaft 60 protrudes from the rotation transmission hole 61c of the cover body 31A, and an end cap 63 having a screwing hole 62 screwed to the tip is attached at the center. The end cap 63 is formed in a cylindrical section with the downstream side opened and the upstream side closed, and the screw hole 62 is firmly screwed to the tip of the rotation transmission shaft 60, so that the end cap 63 The downstream outer peripheral edge 84 is in pressure contact with the plate surface of the cover body 31A. Thus, the rotating body 35, the mounting support body 54, the cutout plate 31, and the cover body 31A are integrated by receiving a pressing force in the axial direction of the rotation transmission shaft 60.

-Drive transmission mechanism and drive device-
A drive transmission mechanism 69 for applying a rotational force around the axis to the rotation transmission shaft 60 is provided at the downstream end of the rotation transmission shaft 60. A drive device 15 for applying a rotational drive force to the drive transmission mechanism 69 is provided. As shown in FIG. 1, the driving device 15 is disposed on the center side of the rotary table 3 with respect to the cutting mechanism 6. The driving device 15 is controlled by a control unit (not shown).

  The drive transmission mechanism 69 and the drive device 15 are covered with a transmission arm member 70 passed to both. The transmission arm member 70 extends outward in the radial direction from the center side of the rotary plate 22 along the radial direction of the rotary plate 22. Further, the transmission arm member 70 is rotatably provided around a support shaft member 183, which will be described later, which is supported on the base 18 (see FIG. 5A) side so as to rotatably support the base side at the lower part thereof. It has been.

  The drive transmission mechanism 69 includes a driven pulley 72 and the like that are fitted and fixed to the downstream side of the rotation transmission shaft 60. The rotation transmission shaft 60 has a transmission arm member 70 via a bearing 73. Are inserted into the front portions of both side plates 74.

  As shown in FIGS. 1 and 3, the drive device 15 includes a rotation drive unit 75 and a transmission belt 76 that transmits the operation of the rotation drive unit 75 to the drive transmission mechanism 69 side (that is, the cutting mechanism 6 side). Have. The rotation drive unit 75 includes a rotation drive motor 77 attached to be placed on the upper surface of the base portion on the center side of the rotary table 3 in the transmission arm member 70, and a motor shaft 78 protruding downward from the rotation drive motor 77. A worm gear 80 attached to the rotary drive shaft 77, a rotation center shaft 81 disposed on the lower side of the rotation drive motor 77 and parallel to the rotation transmission shaft 60, and externally fitted to a middle portion of the rotation center shaft 81 to mesh with the worm gear 80. A rotating gear 82 and a driving pulley 83 that is fitted and fixed on the downstream side of the rotation center shaft 81. The transmission belt 76 is wound around a driven pulley 72 and a drive pulley 83.

  According to the configuration of the drive transmission mechanism 69 and the drive device 15 as described above, by rotating the rotation drive motor 77, the worm gear 80 rotates together with the motor shaft 78, and the rotation is transmitted to the rotation gear 82. The rotation center shaft 81 rotates about its axis together with the rotation gear 82, the drive pulley 83 externally fitted and fixed to the rotation center shaft 81 rotates together, and the rotational force is transmitted via the transmission belt 76 to the driven pulley 72. The rotation transmission shaft 60 rotates together with the driven pulley 72, and the scraping portion of the cutting mechanism 6 fixed to the rotation transmission shaft 60 rotates around the axis of the rotation transmission shaft 60, so that the cutting plate The powder 5 on the groove bottom surface 10 can be cut out by 31 so as to be scraped radially outward of the rotary table 3.

-Cutting mechanism (other configurations)-
In the cutting mechanism 6 having the above-described configuration, the downstream outer peripheral edge 84 of the end cap 63 is formed on the end of the cover body 31A by firmly screwing the screw hole 62 of the end cap 63 to the tip of the rotation transmission shaft 60. The partition plate 30, the rotating body 35, the mounting support body 54, the cutout plate 31, and the cover body 31 </ b> A are integrated by receiving the pressing force in the axial direction of the rotation transmission shaft 60 by being pressed against the plate surface from the upstream side. It is as above-mentioned that it is a thing.

  When the base end plate portion 50 of the cutout plate 31 is attached to the support concave portion 56 of the mounting support 54, one spacer 46 is configured to protrude upstream from the support concave portion 56. Since the other spacer 47 protrudes further downstream from the downstream end face of the mounting support 54 when the attachment is attached, the screw hole 62 of the end cap 63 is formed at the tip of the rotation transmission shaft 60. By firmly screwing, one spacer 46 is pressed against the cover body 31A from the upstream side, and the other spacer 47 is pressed against the plate surface of the partition plate body 33 from the downstream side.

  Since the spacers 46 and 47 are made of an elastic body, an elastic repulsion force corresponding to the amount of compression is generated, one spacer 46 presses the cover body 31A, and the other spacer 47 is the partition plate body. 33 is pressed, there is no room for gaps to be generated between the cutout plate 31 and the partition plate body 33, and between the cutout plate 31 and the cover body 31A.

  For this reason, even if the cutting mechanism 6 is rotationally driven to cut the powder 5 into the hopper 44, the powder 5 is engaged between the cut plate 31 and the partition plate body 33, and the cut plate 31 and the cover body 31A. It is possible to prevent the inconvenience of being inserted. Thus, since the powder 5 does not remain between the members of the cutting mechanism 6 when the powder 5 is packaged, the necessary packaging accuracy is ensured even when a small amount of the powder 5 is packaged. be able to.

  Further, since the partition plate 30 and the cut plate 31 are assembled as separate members, for example, when the ring body 34 or the elastic blade 45 is damaged by use (by sliding the groove bottom surface 10), Since each member can be maintained (replaced) separately, an increase in running cost can be suppressed.

-Cutout switching mechanism-
FIG. 5 is a front view mainly showing the cut-out portion switching mechanism 12, (a) is a front view of the cut-out portion switching mechanism 12 when the cut-out mechanism 6 is in the separation posture B, and (b) is a cut-out mechanism. 6 is a front view of the cut-out portion switching mechanism 12 when 6 is set as a cut-out posture A. FIG.

  The cutout switching mechanism 12 will be described. As shown in each drawing of FIG. 5, the cutout switching mechanism 12 is an operation unit for switching the postures of the cutout plate 31 and the partition plate 30 in the cutout mechanism 6, and the cutout plate 31 and the partition plate 30. The cutting posture A is capable of cutting out the powder 5 by contacting the groove bottom surface 10, and the separation posture B in which the cutting plate 31 and the partition plate 30 are separated upward from the groove bottom surface 10 so that the powder 5 cannot be cut out. It is to switch. The cutout switching mechanism 12 is controlled by a control unit (not shown).

  The cutout switching mechanism 12 includes a lifting motor 85 as a driving means provided on the center side of the rotary table 3 on the base 18 below the rotary table 3, and a rotation transmission shaft 60 by driving the lifting motor 85. The raising / lowering cam 87 rotates around the parallel raising / lowering horizontal axis 86, and a conversion mechanism (not shown) that converts the drive of the raising / lowering motor 85 into rotation around the raising / lowering horizontal axis 86 of the raising / lowering cam 87. Yes.

  The raising / lowering cam 87 is arrange | positioned under the transmission arm member 70 in the area | region corresponded in the longitudinal direction, The outer peripheral surface has the plane part 88, the large curvature part 90 with a large curvature, and a large curvature. A small curvature portion 91 having a smaller curvature than the portion 90 is provided, and the large curvature portion 90 is continuously formed on both sides of the plane portion 88. The large curvature portion 90 and the small curvature portion 91 can be slidably contacted with the outer peripheral surface of the cam roller 94 provided inside the transmission arm member 70, and the flat portion 88 is large so that it cannot contact the cam roller 94. Relationships such as the curvature of the curvature portion 90 and the large curvature portion 90, the distance from the elevating horizontal shaft 86 to the cam roller 94, and the like are set.

  That is, when the large curvature portion 90 or the small curvature portion 91 of the lifting cam 87 is in contact with the cam roller 94, the cutout plate 31 is in the separation posture B and the groove bottom surface 10 as shown in FIG. It is away from. On the other hand, in the state where the flat portion 88 of the lifting cam 87 faces the cam roller 94 below, the partition plate 30 and the cutting plate 31 are in the cutting posture A and the groove bottom surface 10 as shown in FIG. Touching.

-Operation of the packaging device-
Next, the operation of the packaging device 1 having the above-described configuration will be described with reference to FIG. 7 (flow diagram). In the packaging device 1, the powder 5 is cut out by the cutting mechanism 6 under the control of a control unit (not shown). In addition to this cutting operation, the cutting mechanism 6 and the groove bottom surface 10 are cleaned. However, the description of the configuration and operation of this cleaning is omitted.

  The cutting operation of the powder 5 by the cutting mechanism 6 will be described. A rotation drive motor (not shown) is driven to rotate the rotary table 3 and the rotary plate 22 about the vertical axis 2 (clockwise direction R1 in FIG. 1) (step S1), and supply means such as a feeder (not shown) Thus, the powder 5 is supplied so as to be sprinkled evenly around the entire circumference of the annular groove 4 of the rotating plate 22 (step S2). After the supply of the powder 5 is finished (step S3), the rotation of the rotary table 3 and the rotary plate 22 is stopped (step S4).

  At this stage, as shown by a two-dot chain line in FIG. In particular, the separation posture B of the cutting mechanism 6 is such that the large curvature portion 90 or the small curvature portion 91 of the lifting cam 87 is in contact with the outer peripheral surface of the cam roller 94 as shown in FIG. The transmission arm member 70 is rotated upward around the support shaft member 183 to maintain its posture.

  Then, after the supply of the powder 5 is finished and the rotation of the rotary table 3 and the rotary plate 22 is stopped, the cutting mechanism 6 is set to the cutting posture A as shown by a broken line in FIG. 3 (step S5). The cutting mechanism 6 is set to the cutting posture A by driving the cutting part switching mechanism 12. That is, as shown in FIG. 5, by driving the raising / lowering motor 85, the raising / lowering cam 87 is rotated around the raising / lowering horizontal shaft 86, and the flat portion 88 is opposed to the cam roller 94 downwardly, thereby raising / lowering the cam. This can be achieved by making 87 a non-contact with the cam roller 94. The partition plate 30 and the cutting plate 31 of the cutting mechanism 6 are stationary without rotating around the horizontal axis (rotation transmission shaft 60) from the separation posture B to the cutting posture A.

  After the cutting mechanism 6 is set to the cutting posture A in this way, as shown in FIG. 6A, the rotary table 3 and the rotary plate 22 are reversely rotated in the direction R2 by a predetermined amount (step S6). 6A to 6C are schematic diagrams for explanation, and illustration of the powder 5 actually present on the right side of the partition plate 30 is omitted. The predetermined amount of reverse rotation may be a rotation amount that allows the partition plate 30 to push out the powder 5 on the annular groove 4 so as not to affect the packaging near the end of the packaging, such as the final packaging. Specifically, when it is expressed by a length along the circumferential direction at the center of the groove bottom surface 10 in the annular groove 4, it is preferably 1.5 mm to 8 mm, more preferably 3 mm to 7 mm. In this embodiment, the rotary table 3 and the rotary plate 22 are set to rotate reversely by 5 mm. Even at this stage, the partition plate 30 and the cutting plate 31 of the cutting mechanism 6 remain stationary without rotating around the horizontal axis (rotation transmission shaft 60). By the reverse rotation, the powder 5 located on the downstream side surface of the partition plate 30 (based on the rotation direction of the rotary table) is pushed out by the partition plate 30 and moves downstream.

  As described above, at this stage, the ring body 34 of the partition plate 30 does not rotate around the horizontal axis 60 while contacting the groove bottom surface 10 of the annular groove 4. For this reason, when the powder 5 is pushed out by the partition plate 30 and moved to the downstream side as described above, the powder 5 in contact with the downstream side surface of the partition plate 30 is guided by the rotation of the partition plate 30 and from the annular groove. It can be prevented from popping out. The amount of reverse rotation is slightly (1.5 mm to 8 mm) as compared with the entire circumference of the annular groove 4, so that the ring body 34 is in contact with the groove bottom surface 10 of the annular groove 4. Even when the configuration does not rotate around the shaft 60, vibration (chatter) and noise are unlikely to occur.

  The reverse rotation is instructed by an operator such as a pharmacist (in this embodiment, the operator gives an instruction to perform the granular powder packaging on the operation panel of the packaging device 1 by a touch operation on the operation panel or the like ( For example, when the “granule packing” button on the operation panel is pressed), when the number of packings related to the packing instruction is large (in this embodiment, the number of packings of 77 or more is specified by the operator) In the case where the height of the peak of the powder 5 supplied onto the annular concave groove 4 is larger than the specified height (the height of the peak of the powder 5 is detected by, for example, the sensor Se shown in FIG. 3). Only done when all three conditions are met. In addition, regarding the condition of the “operator instruction”, instead of this, the control unit or the like of the packaging device 1 receives prescription data input by the operator, and the prescription data may be a granular powder. It may be included as a condition.

  When the reverse rotation is performed, after the reverse rotation, as shown in FIG. 6B, the rotary table 3 and the rotary plate 22 are rotated forward in the direction R1 by the same predetermined length as described above (step S7). ). That is, the positional relationship among the rotary table 3 and the rotating plate 22 and the cutting mechanism 6 returns to the positional relationship before the reverse rotation.

  Due to this forward rotation, the upstream end of the powder 5 that has been moved downstream by the reverse rotation on the basis of the forward rotation direction of the rotary table (that is, the end of the “crest” on the final package side of the powder 5) 5a; A gap is formed by separating from the partition plate 30. Or even if it does not reach a clearance gap, the contact amount with respect to the partition plate 30 of the powder 5 reduces compared with before performing the said reverse rotation.

  After the above, as shown in FIG. 6C, a normal packaging operation is started. That is, by rotating the cutting mechanism 6 around the rotation transmission shaft 60 that is a horizontal axis, the powder 5 in a predetermined circumferential direction is cut out radially outward of the rotary table 3 and the hopper 44 (FIGS. 1 and 3). (See step S8 to S10). The cutting mechanism 6 of this embodiment makes one rotation for every one package (the cutting plate 31 scratches the annular groove 4). When the cutting mechanism 6 is in the cutting posture A, the center of the rotation transmission shaft 60 is set to be located slightly below the center of curvature of the groove bottom surface 10 of the annular groove 4. Since the partition plate 30 and the cutout plate 31 are integrated as described above, the partition plate 30 also rotates as the cutout plate 31 rotates. When the partition plate 30 is rotating, the contact position of the ring body 34 with the annular groove 4 changes every moment. For this reason, the ring body 34 is dragged by the rotation of the annular groove 4, and it is possible to suppress the ring body 34 from generating fine vibration (chatter) and accompanying noise. In FIG. 7, “cutting mechanism rotation” is described in both step S8 and step S10. However, in step S8, the cutting plate 31 removes the annular groove 4 (the powder 5 on the annular groove 4). The cutting mechanism 6 is rotated within an angle range that does not scratch, and in step S10, the cutting mechanism 6 is rotated within an angle range in which the cutting plate 31 scratches the annular groove 4 (the powder 5 on the annular groove 4). . The rotation of the turntable 3 is stopped at the time of step S10 (step S9). Therefore, the powder 5 is cut out in step S10.

  In order to rotate the cutting mechanism 6 around the rotation transmission shaft 60, as described above, when the rotation driving motor 77 is driven, the worm gear 80 and the motor shaft 78 are rotated and the rotation is transmitted to the rotation gear 82. The rotation center shaft 81 rotates around the axis together with the rotation gear 82, the drive pulley 83 rotates, and the rotational force is transmitted to the driven pulley 72 via the transmission belt 76, and the rotation transmission shaft 60 together with the driven pulley 72. And the cutting mechanism 6 fixed to the rotation transmission shaft 60 rotates around the axis of the rotation transmission shaft 60.

  As described above, when the reverse rotation is performed, there is a gap between the upstream end 5a of the powder 5 and the partition plate 30, or the amount of contact of the powder 5 with the partition plate 30 is small. It can be reduced. For this reason, when the powder 5 is cut out by the cutting mechanism 6, the powder 5 that has been in contact with the downstream side surface of the partition plate 30 as in the prior art is guided by the rotation of the partition plate 30 and jumps out of the annular groove. Can be suppressed. Therefore, the prescribed amount of powder 5 can be wrapped in the first packaged package. In addition, a prescribed amount of the powder 5 can be wrapped even in a package that is close to the end of the package, such as a package that has been packaged last.

  Subsequent to the first package, the driving device is intermittently driven to rotate the rotary table 3 and the rotary plate 22 about the vertical axis 2 intermittently (with an equal amount of rotation) (step S9). 3 and the rotating plate 22 stop rotating, the cutting mechanism 6 is rotated around the rotation transmission shaft 60, and the powder 5 is cut out radially outside the rotary table 3 by the cutting plate 31 and packaged ( The operation of step S10) is sequentially repeated until the powder 5 is cut out in the entire circumferential range of the annular groove 4 (steps S8 to S11). In accordance with the intermittent rotation of the rotary table 3 and the rotary plate 22, the cutting position by the cutting mechanism 6 is sequentially changed.

  When cutting the powder 5 outward in the radial direction of the turntable 3, the powder 5 is cut by the rotation of the cutting plate 31 with the cutting range restricted by the partition plate 30 and the cover body 31A. At this time, the tip of the elastic blade 45 slides on the groove bottom surface 10 of the annular groove 4 so that the powder 5 is squeezed.

  Finally, the cutting mechanism 6 moves from the cutting posture A to the separation posture B and ends the packaging operation (step S12).

-Modification of the embodiment-
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the summary of this invention.

  In the said embodiment, although the cut-out board 31 was taken up as what functions as a cut-out part, it is not limited to this. For example, the structure which extrudes the powder 5 with a cylinder, and the structure which blows off the powder 5 by air can also be employ | adopted. Moreover, you may be comprised so that it may reciprocate in the linear direction instead of the structure which the cutting plate 31 rotates.

  Moreover, in the said embodiment, although the partition plate 30 and the cutting plate 31 are integrated, it is not limited to this, It is comprised so that the partition plate 30 and the cutting plate 31 may rotate independently independently. May be. In some cases, the partition plate 30 may be configured not to rotate (becomes fixed) but to rotate only the cutout plate 31.

  Moreover, in the said embodiment, although it has comprised so that the powder 5 may be scraped off to the radial direction outer side of the turntable 3 with the cutting plate 31, it is comprised so that it may cut out radially inward. It may be.

  In the above-described embodiment, the rotary table 3 and the rotary plate 22 are rotated with respect to the cutting mechanism 6 that does not rotate around the vertical axis. One may be rotated relative to the other. Therefore, the cutting mechanism 6 may be configured to move along the circumferential direction of the rotating plate 22 that does not rotate around the vertical axis.

  Further, in the above embodiment, the rotary table 3 and the rotary plate 22 are intermittently rotated around the vertical axis 2 with an equal rotation amount in the entire circumferential range of the annular groove 4, and the powder 5 is dispersed by the cutting mechanism 6. The rotary table 3 is cut out radially and packaged. However, depending on various conditions such as the amount of powder 5 to be supplied, its particle size, and the number of packets specified by the operator, the “disintegration” of the powder 5 on the annular groove 4 occurs. The height of the “mountain” may be different. In this case, even if the rotary table 3 and the rotating plate 22 are intermittently rotated at an equal rotation amount, the actual amount of the powder 5 cut out from each cutting range for each intermittent rotation by the cutting plate 31 is the same. May differ from the prescribed amount. In this case, based on the experimental data obtained in advance, the rotation of the rotary table 3 and the rotary plate 22 about the vertical axis 2 in each cutting range so that the powder 5 cut out from each cutting range becomes a specified amount. The amount may be configured to be individually set (adjusted) by, for example, calculation by the control unit.

  Moreover, in the said embodiment, the rotational speed at the time of forward rotation of the turntable 3 and the rotating plate 22 and the rotational speed at the time of reverse rotation are the same. However, the present invention is not limited to this, and the rotational speed at the time of reverse rotation may be configured to be slower than the rotational speed at the time of forward rotation. With this configuration, when the powder 5 located on the downstream side of the partition plate 30 is pushed out by the partition plate 30 and moved to the downstream side, vibration (chatter) and noise can be generated without rotating the ring body 34. Can be difficult to generate.

-Configuration and operation of the embodiment (summary)-
Lastly, the configuration of the above embodiment and the effects achieved by the configuration will be summarized. In the above-described embodiment, in the packaging device 1 that separates a plurality of packages by a predetermined amount by cutting out the supplied powder 5, the rotary table 3 having an annular groove 4 in which the powder 5 can be disposed, and the annular recess A cutting mechanism 6 for cutting out the powder 5 supplied to the groove 4 over the entire circumference by a predetermined area along the circumferential direction of the rotary table 3 in the radial direction of the rotary table 3, and the rotary table 3 and a control unit that controls the operation of the cutting mechanism 6, one of the rotary table 3 and the cutting mechanism 6 rotates relative to the other about the vertical axis 2, and The extraction mechanism 6 includes a cutting plate 31 for moving the powder 5 by moving across the annular concave groove 4 in the radial direction, and the cutting mechanism 6 that is associated with the relative rotation at the time of cutting. Further, on the downstream side of the cutting plate 31 with respect to the moving direction of the rotary table 3 A partition plate 30 to be placed, and the control unit brings the partition plate 30 into contact with the annular groove 4 and then sets one of the rotary table 3 and the cutting mechanism 6 to the other. The powder 5 is cut out from the annular groove 4 by moving the cutting plate 31 in the radial direction while relatively rotating in one direction intermittently. After being supplied over the entire circumference of the concave groove 4, the partition plate 30 is brought into contact with the annular concave groove 4 before the first cutting out, and then the rotary table 3 and the cutting mechanism 6 are contacted. One of the powders 5 is rotated relative to the other in the direction opposite to the time of the cutting, so that a part of the powder 5 for the last cutting is placed on the annular groove 4 by the partition plate 30. In this case, the packaging device is moved to the downstream side.

  According to this configuration, the powder 5 that is finally cut out due to the relative rotation in the reverse direction is between the end portion (the end of the “mountain”) 5 a near the partition plate 30 and the partition plate 30. It can be in a state where a gap is formed or a state in which the amount of contact of the powder 5 with the partition plate 30 is reduced.

  For this reason, when the powder 5 is cut out by the cutting mechanism 6, the powder 5 that has been in contact with the downstream side surface of the partition plate 30 is guided by the rotation when the partition plate 30 is rotated and is released from the annular recess 4. Jumping out can be suppressed. Therefore, the prescribed amount of powder 5 can be wrapped in the first packaged package. In addition, a prescribed amount of the powder 5 can be wrapped even in a package that is close to the end of the package, such as a package that has been packaged last. Thus, the powder 5 that has been in contact with the downstream side surface of the partition plate 30 is prevented from being guided by the rotation of the partition plate 30 and jumping out of the annular recess 4, and can be packaged in an accurate amount.

  Further, the annular groove 4 has a groove bottom surface 10 formed in a circular arc shape that protrudes downward with the center of curvature as the center, and the partition plate 30 has a curvature of the outer peripheral portion 43 of the groove bottom surface 10. A disk-like shape that substantially matches the curvature, is rotatable about a horizontal axis 60 along the circumferential direction of the annular groove 4, and includes a ring body 34 formed of a soft material on the outer periphery, and this partition When the plate 30 rotates one of the rotary table 3 and the cutting mechanism 6 in the opposite direction relative to the other, the ring body 34 contacts the groove bottom surface 10 of the annular groove 4. However, the ring body 34 is configured not to rotate around the horizontal axis 60 but to rotate around the horizontal axis 60 while being in contact with the groove bottom surface 10 of the annular groove 4 at the time of cutting. Yes.

  According to this configuration, since the partition plate 30 contacts the groove bottom surface 10 of the annular groove 4 while rotating around the horizontal axis 60, the contact position of the partition plate 30 with respect to the annular groove 4 changes every moment. . Therefore, it is possible to suppress vibration (chatter) caused by the ring body 34 formed of a soft material being dragged in one direction by the relative rotation of the rotary table 3 and the cutting mechanism 6 and the generation of noise associated therewith.

  Further, when one of the rotary table 3 and the cutting mechanism 6 is rotated with respect to the other (forward / reverse rotation), the ring body 34 is configured to rotate around the horizontal axis 60 so as to vibrate (battery). However, when one of the rotary table 3 and the cutting mechanism 6 is rotated in the opposite direction relative to the other, the ring body 34 is the groove bottom surface of the annular groove 4. 10 is configured to not rotate around the horizontal axis 60 while being in contact with 10, when the powder 5 located on the downstream side of the partition plate 30 is pushed out by the partition plate 30 and moved to the downstream side, the downstream side surface of the partition plate 30. It is possible to prevent the powder 5 in contact with the liquid from being guided by the rotation of the partition plate 30 and jumping out of the annular groove. The amount of reverse rotation is such that it does not affect the packaging near the end of the packaging, such as the final packaging (specifically, when expressed by the length along the circumferential direction at the center of the groove bottom 10) 1.5 mm to 8 mm), or a state in which a gap is created between the partition plate 30 and the end portion 5a (the end of the “mountain”) near the partition plate 30 of the powder 5 to be finally cut out, or The amount of rotation of the powder 5 with respect to the partition plate 30 only needs to be reduced, and the amount of rotation is small. Therefore, the ring body 34 is in contact with the groove bottom surface 10 of the annular groove 4 and the horizontal axis 60. Even when it is configured not to rotate around, vibration (chatter) and noise are hardly generated. Further, the speed of relative rotation between the rotary table 3 and the cutting mechanism 6 when the powder 5 located on the downstream side of the partition plate 30 is pushed out by the partition plate 30 and moved to the downstream side is set to the rotary table 3 at the time of cutting. It is desirable to make it slower than the speed of relative rotation with the cutting mechanism 6. In this desirable configuration, when the powder 5 located on the downstream side of the partition plate 30 is pushed out by the partition plate 30 and moved to the downstream side, vibration (chatter) and noise are hardly generated even if the ring body 34 is not rotated. .
