The spring body 121 has a plate-like base portion 122 fixed to the back surface of the cross wall body 110, and is integrally formed from a plate-like base portion 122 and a presser portion 123 inclined downward in the radial direction from the plate-like base portion 122. Is formed.

The brush portion 101 is a plate-like shape in which a first brush group 125 in which a first removal brush 124 made up of a bundle of a plurality of brushes is arranged in a horizontal direction and a base portion of a bundle of brushes in each first removal brush 124 is implanted. It is comprised from the planting body 126. FIG. The planted body 126 has a pair of left and right support holes 127 formed on the plate surface, and a protrusion 128 that fits into the support hole 127 is formed at the front portion of the top wall 104. By installing the planted body 126 at the front portion of the top wall 104 so that the protrusion 128 fits into the support hole 127, most of the brush portion 101 is stored in the storage space 112, and the first removal brush 124 (first The front end of the brush group 125) protrudes toward the cutout 6 at a position above the duct suction port 107.
Note that the length of the brush (first removal brush 124) in the front-rear direction is the same.

  The front surface 130 of the planted body 126 is formed in an arcuate curved surface that is convex forward in plan view, and the first removal brushes 124 are arranged side by side in the circumferential direction of the front surface 130. Each first removal brush 124 is planted along the normal direction of the front surface 130. In addition, each first removal brush 124 has the same planting depth from the front surface 130 of the planted body 126. Therefore, the imaginary line which connected the front-end | tip of each 1st removal brush 124 becomes a curve with the same curvature as the front surface 130 of the planting body 126. FIG.

In this embodiment, five bundles of first removal brushes 124 are provided, and the first removal brushes 124a arranged at the center in the circumferential direction are arranged in parallel to the plate surfaces of the partition plate 30 and the cover body 31A, and are arranged on the downstream side in the circumferential direction. The two bundles of first removal brushes 124b are arranged on the partition plate 30 side so as to be inclined to the downstream side in plan view with respect to the plate surface of the partition plate 30, and the two bundles of the first removal brush 124b on the upstream side in the circumferential direction. The brush 124c is disposed on the cover body 31A side so as to be inclined toward the upstream side in plan view with respect to the plate surface of the cover body 31A.

  Since the first removal brush 124 is composed of a bundle of brushes, the brushes converge at the planting portion on the front surface of the planted body 126, and the convergence is released at the tip side, so that the interval between the brushes is widened. Therefore, in general, in a brush composed of a bundle of brushes, the tip end side has a larger contact area with the object than the base end side. Similarly, when viewed with a bundle of first removal brushes 124, the contact area with the object is larger on the tip side than on the planted portion. Moreover, the front surface 130 of the planted body 126 is formed to be an arcuate curved surface that protrudes forward, so as to incline and come into contact with the plate surfaces of the partition plate 30 and the cover body 31A that are objects. By providing in, it is comprised so that a contact area may become still larger.

  The connecting wall body 110 is configured to be openable and closable around the rear pin member 116. When the front pin member 118 is locked to the hook 120, the tip of the holding portion 123 of the spring body 121 contacts the upper surface of the planting body 126. The planted body 126 is pressed against the front portion of the top wall 104 by the elasticity of the spring body 121.

In order to remove the planted body 126 from the top wall 104 of the suction duct 96, the engagement between the front pin member 118 and the hook 120 is released by pressing the connecting wall body 110 downward and further bending the spring body 121. The engagement is released by moving the front pin member 118 forward from the lower side of the hook 120 by moving the front wall member 110 forward with the rear pin member 116 along the elongated hole 117. It is made to open around the rear pin member 116.
By doing so, the storage space 112 is opened upward, so that the brush portion 101 can be detached from the suction duct 96 by removing the planted body 126 from the projection 128.

  A discharge hole 131 is formed in the rear portion of the bottom wall 102 of the suction duct 96, and the tip end of the suction hose 100 is connected to the discharge hole 131. It is comprised so that the powdered medicine 5 which reached the inside of the suction duct 96 and the discharge hole 131 may be sucked toward a predetermined place. The discharge hole 131 is opened inside the suction duct 96 so as to communicate with the duct suction port 107.

  As the first cleaning portion 7, a spray hole 132 is formed in the middle of the flat plate portion 23 of the blocking plate 66 in the vertical direction, and the tip of the spray nozzle 98 is connected to the spray hole 132 on the back side of the flat plate portion 23. . The cleaning air 134 is configured to be discharged slightly upward from the tip of the spray nozzle 98 through the spray hole 132. That is, the discharge part of the cleaning air 134 is composed of the spray nozzle 98 and the spray hole 132 of the blocking plate 66, and the suction part of the cleaning air 134 is composed of the suction duct 96 and the suction hose 100.

7 and 8 are enlarged front views of the first cleaning unit switching mechanism 13, respectively. Here, the first cleaning unit switching mechanism 13 for switching the posture of the first cleaning unit 7 between the cleaning posture C and the non-cleaning posture E will be described.
As shown in FIGS. 2, 7, 8, etc., the first cleaning unit switching mechanism 13 is a link having a pair of front link members 135 and rear link members 136 inside and outside in the radial direction and the lifting cam 87. It consists of a mechanism (a parallel link mechanism is used). The first cleaning unit switching mechanism 13 is configured as an interlocking unit that operates in conjunction with the operation of the cutting unit switching mechanism 12, and the suction duct 96 is located above and below the rotary table 3 with respect to the cutting unit 6. It has the structure moved along a radial direction.

  The front link member 135 is formed in a substantially triangular flat plate shape, and is provided so as to be rotatable around a front rotation central axis 137 provided at one apex portion, and the rear link member 136 is formed in a bowl shape. The front rotation center axis 137 and the rear rotation center axis 138 are predetermined except for the suction duct 96 (extension bracket 106). It is provided to rotate on the spot.

One apex portion (upper apex portion) of the front link member 135 is rotatably provided on the plate surface of the extension bracket 106 that extends downward from the bottom wall 102 of the suction duct 96 via the rotary pin member 150. It has been. The duct cam roller 92 is provided at one vertex of the front link member 135 (vertical portion on the lifting cam 87 side) so as to be rotatable around a horizontal axis 92a that is the center of rotation. The horizontal shaft 92a is disposed so as to be displaced toward the rear rotation center shaft 138 with respect to the front rotation center shaft 137, and connects the rotation pin member 150, the front rotation center shaft 137, and the horizontal shaft 92a. The formed virtual connection area is a triangle.
The front link member 135 swings about the front rotation center axis 137 when the elevating cam 87 rotates about the elevating horizontal axis 86 and the cam pin 97 and the duct cam roller 92 come into contact with each other between the outer peripheral surfaces thereof. . The elevating cam 87 is disposed below the front rotation center shaft 137 and the rear rotation center shaft 138.

  Thus, the lifting cam 87 is also used as a means for changing the posture of the suction duct 96, and the lifting cam 87 is disposed below the transmission arm member 70 in a region corresponding to the middle of the longitudinal direction, Since the link mechanism is operated by the rotation of the elevating cam 87, the mechanism portion for changing the postures of the cutout portion 6 and the suction duct 97 is made compact compared to the conventional one.

  The other end side of the rear link member 136 is rotatably provided on the rear surface of the extension bracket 106 via a rotation pin member 151. Each rotation is such that an imaginary line connecting the center of the rotation pin member 150 and the center of the front rotation center axis 137 and a virtual line connecting the center of the rotation pin member 151 and the center of the rear rotation center axis 138 are parallel to each other. The positions of the pin members 150, 151, the front rotation center shaft 137, and the rear rotation center shaft 138 are related.

  A spring body 39 (tensile spring) for biasing the suction duct 96 to the non-cleaning posture E is provided. The front end 39a side, which is one end of the spring body 39, is locked to the plate surface of the front link member 135, and the rear end 39b side, which is the other end of the spring body 39, is fixed at an appropriate place. The suction duct 96 is biased to the non-cleaning posture E. The spring body 39 is located slightly below the rear end side compared to the front end side.

  FIG. 9 is a plan sectional view of the second cleaning unit 8. Here, the 2nd cleaning part 8 is demonstrated. The second cleaning part 8 is a removing means for removing the powder 5 remaining in the annular groove 4 after being cut out by the cutting part 6 as shown in FIGS. And a rotary wiping body 154. The brush body 153 and the rotary wiping body 154 are provided so as to be rotatable about the horizontal axis around the horizontal axis above the annular groove 4.

  The rotary wiping body 154 includes a rotation center plate 155 on the rotation center side and a wiping body 156 fixed to the outer peripheral portion of the rotation center plate 155. For example, a felt is preferably used as the wiping body 156. The rotation center plate 155 is formed in a thin disk shape, and a rotation center shaft 157 as a horizontal axis is fixed to the center thereof. The rotation center shaft 157 is configured as a motor shaft of the rotation drive motor 158.

The brush body 153 includes a rotation center body 160 on the rotation center side, and a plurality of bundles of second removal brushes 161 that are radially planted around the rotation center body 160 on the outer peripheral surface thereof. The rotation center body 160 is formed in a polygonal shape (regular octagon in the figure) when viewed from the front, and is formed in a prismatic shape (plate shape having a predetermined thickness) with the rotation center axis 157 in the height direction.
The brush body 153 is attached to the rotation center shaft 157 so as to be adjacent to the upstream side of the rotary wiping body 154 in the rotation direction of the rotary table 3.

  Each of the second removal brushes 161 is composed of a bundle of a plurality of brushes, and the plurality of second removal brushes 161 are defined as a second brush group 163, and a plurality of rows (in the figure, between the apex sides 162 of the rotation center body 160). Three rows of second removal brushes 161 are arranged so as to protrude in the radial direction of the rotation center body 160. In each second brush group 163 between the apex corner sides 162, the second removal brush 161 is arranged to be inclined with respect to the apex corner side 162.

  That is, the second removal brushes 161 in each second brush group 163 are arranged along the rotational direction in a direction that follows the circumferential direction of the annular groove 4 (the rotary table 3). By arranging in this way, when the second removal brushes 161 are viewed in the thickness direction of the rotation center body 160 or viewed from the front-rear direction, the adjacent second removal brushes 161 can be overlapped. . If it does so, the number of the brushes of each 2nd removal brush 161 will be increased, and the adjacent 2nd removal brush 161 will not contact. That is, even if the configuration of the second removal brush 161 uses a brush that bundles a plurality of brushes in a circular shape at intervals, the second removal brushes 161 can be closely arranged. Yes, the cleaning ability for the object to be cleaned can be improved.

In the figure, a configuration in which only three rows of the second removal brushes 161 are arranged in the width direction on each outer peripheral surface between the apex sides 162 is shown. It is also possible to arrange the second removal brushes 161 adjacent to each other in the circumferential direction one by one and provide a total of five bundles of the second removal brushes 161 on each outer peripheral surface between the apex sides 162. Also in this case, the second removal brushes 161 can be overlapped when viewed in the thickness direction of the rotation center body 160 or when viewed from the front-rear direction, and the cleaning ability for the cleaning object can be improved.
In addition, the protrusion amount of the brush from the outer peripheral surface of the rotation center body 160 in each second removal brush 161 is substantially the same.

  The rotary wiping body 154 and the brush body 153 are provided on the rotation center shaft 157 so as to be adjacent to the direction (front-rear direction) substantially along the circumferential direction of the turntable 3, and the rotation center of the rotation center shaft 157 is the rotation center of the brush body 153. An end cap 64 is detachably attached to a portion protruding from the body 160, and the end cap 64 prevents the rotary wiping body 154 and the brush body 153 from being detached from the rotation center shaft 157.

The second cleaning unit 8 including the rotary wiping body 154 and the brush body 153 is covered with a covering body 164 that opens a region corresponding to the groove 24 of the rotating plate 22. The cover 164 includes a back plate 165 and a front cover 166, and the back plate 165 has a large diameter disk portion 167 and a lower portion of the disk portion 167 in the radial direction of the rotating plate 22 compared to the brush body 153. A projecting plate portion 168 projecting outward is formed integrally.
A joint pipe portion 170 (introduction path) that protrudes further rearward is formed on the back surface of the protruding plate portion 168, and an introduction pipe 171 for the powder 5 is connected to the joint pipe portion 170. An inlet of the joint pipe portion 170 is opened as a suction port 172.

  Of the inner peripheral surface of the joint pipe part 170 introduced from the suction port 172 to the joint pipe part 170, the region on the second cleaning part 8 (removing means) side expands toward the front lower side and the brush body 153 side. An inclined surface 173 is formed. In particular, the lower surface 174 of the inclined surface 173 extends downward, and converges in the vicinity of the virtual extension line 10b obtained by extending the groove bottom surface 10 of the annular groove 4 of the rotating plate 22 with its curvature in the cleaning posture D. It is formed as follows.

Thus, the suction port 172 is not formed radially outward of the removing means by being formed in the protruding plate portion 168 of the back plate 165, and the suction port 172 is disposed at the radially outward position and behind the removing means. Has been. In other words, the suction port 172 is opened in a direction orthogonal to the plane including the second removal brush 161 at the same position in the front-rear direction in each second brush group 163 between the apex sides 162. .
The rotational drive motor 158 is attached to the rear surface of the back plate 165.

When the second cleaning portion 8 is set to the cleaning posture F, a notch 165a that can avoid interference with the groove member 25 is formed across the radially inner lower end portion and the side plate portion 175 of the back plate 165. . The notch 165a is formed by a horizontal wall 165b and a vertical wall 165c that hangs down from the radially outer end of the horizontal wall 165b. The radial length of the horizontal wall 165b is formed substantially equal to the radial width of the groove member 25, and the height of the vertical wall 165c is formed substantially equal to the height of the groove member 25.
An extension wall 165d that contacts the upper surface of the flat surface portion 23 of the rotating plate 22 when the second cleaning portion 8 is set to the cleaning posture F by extending in the horizontal direction from the lower end of the vertical wall 165c is formed.

The front cover 166 of the covering body 164 has a depth including the thickness of the rotary wiping body 154 and the brush body 153, covers the removing means radially outwardly, and covers the removing means on the front side. The front plate 176 and the front plate 176 are integrally formed. The front plate 176 is formed in a relative shape with the back plate 165 when viewed from the front.
The back plate 165 and the front plate 176 are fixed by clips 177 so as to be aligned in the front-rear direction at respective radially outer portions. The base end portion of the clip 177 on the back plate 165 side is locked to the shaft body 21 formed on the outer peripheral portion of the back plate 165, and the hook portion 119 on the front end side is attached to the outer peripheral portion of the front plate 176 of the front cover 166. The back plate 165 and the front cover 166 are fixed by elastically locking to a locking piece 178 formed so as to protrude forward.

  The removing means, that is, the rotary wiping body 154 and the brush body 153 can be switched between a cleaning posture D in which the outer peripheral portion can contact the groove bottom surface 10 and a non-cleaning posture F separated from the groove bottom surface 10. The posture is switched by the cleaning unit switching mechanism 14.

  As shown in FIGS. 2, 7, 8, and the like, a plate-like arm member 181 fixed to the rear surface of the back plate 165 with a mounting screw 180 is provided as the second cleaning unit switching mechanism 14. The arm member 181 has a tip 181 a fixed to the rear surface of the back plate 165. A support plate member 182 for attaching and supporting the base portion 181b of the arm member 181 is formed on the base 18 so as to stand upright. A support center serving as a rotation center of the arm member 181 is formed on the support plate member 182. A shaft member 183 is provided as a horizontal axis. The arm member 181 is rotatably provided around the support shaft member 183.

  The second cleaning unit switching mechanism 14 includes the elevating cam 87 and a cam roller 95 that rotates when its outer peripheral surface is in sliding contact. The cam roller 95 can contact only the large curvature portion 90 and the small curvature portion 91 of the elevating cam 87, and the elevating cam 87 and the cam roller 95 so as not to contact the flat portion 88 of the elevating cam 87. Are related. That is, when the flat portion 88 of the lifting cam 87 faces the cam roller 95, the removing means is in the cleaning posture D, and when the large curvature portion 90 or the small curvature portion 91 of the lifting cam 87 contacts the cam roller 95. Moreover, the removing means is in a non-cleaning posture F.

  Next, the operation of the packaging device 1 configured as described above will be described. The operations of the packaging device 1 are [the cutting operation of the powder 5 by the cutting portion 6], [the cleaning operation of the cutting portion 6 by the first cleaning portion 7], [the cleaning of the groove bottom surface 10 by the second cleaning portion 8]. Operation].

[Cutting Operation of Powder 5 by Cutting Unit 6] The drive device is driven to rotate the rotary table 3 and the rotating plate 22 about the vertical axis 2 (clockwise in FIG. 1), while a feeder or the like (not shown) is used. The powder 5 is supplied to the annular groove 4 of the rotating plate 22 by shaking by the supplying means, and the rotation of the rotating plate 22 is stopped.
At this stage, as shown in FIG. The first cleaning unit 7 is in the non-cleaning posture E, and the second cleaning unit 8 is in the non-cleaning posture F. In particular, the separation posture B of the cut-out portion 6 is 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 rotating plate 22 is stopped, the cutting portion 6 is set to the cutting posture A as shown in FIG. In order to set the cutout portion 6 to the cutout posture A, the cutout portion switching mechanism 12 is driven. 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. After the cutting portion 6 is set to the cutting posture A in this way, the cutting portion 6 is rotated around the rotation transmission shaft 60 that is a horizontal axis, so that the powdered medicine 5 in the circumferential region is annularly recessed 4 Is cut out radially outward, put into the hopper 44, and packaged by a packaging unit (not shown). When the cutting portion 6 is set to the cutting posture A, the center of the rotation transmission shaft 60 is set to be slightly below the center of curvature of the groove bottom surface 10 of the annular groove 4.

In order to rotate the cut-out portion 6 around the rotation transmission shaft 60, as described above, when the rotation drive 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 cutout portion 6 fixed to the rotation transmission shaft 60 rotates around the axis of the rotation transmission shaft 60.
Subsequently, the driving device is driven intermittently to rotate the rotating plate 22 about the vertical axis 2 while rotating the cutting portion 6 about the rotation transmission shaft 60 at the timing when the rotation of the rotating plate 22 stops. The powder 5 is cut out over the entire circumferential direction of the annular groove 4 by successively repeating the operation of cutting out and packing the powder 5 outward in the radial direction of the annular groove 4.
When the powder 5 is cut out radially outward of the annular groove 4, the powder 5 is cut by the rotation of the cutting plate 31 in a state where the cutting range is restricted by the partition plate 30 and the cover body 31 </ b> A. Is issued. 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 scooped.

  Further, when the cutting unit 6 is performing the cutting operation, the first cleaning unit 7 is in the non-cleaning posture E that is not in contact with the cutting unit 31. As shown in FIG. 8 and the like, the non-cleaning posture E of the first cleaning portion 7 is such that the large curvature portion 90 or the small curvature portion 91 of the elevating cam 87 contacts the cam roller 94 and the cam pin 97 contacts the duct cam roller 92. If the large curvature portion 90 or the small curvature portion 91 of the elevating cam 87 is in contact with the cam roller 94 and the cam pin 97 is not in contact with the duct cam roller 92. Regardless of whether the cutout portion 6 is in the cutout posture A or the separated posture B, the first cleaning portion 7 maintains the non-cleaning posture E that is not in contact with the cutout portion 6. In the non-cleaning posture E of the first cleaning unit 7, in FIG. 8, the distance Y <b> 1 is from the flat plate 68 of the blocking plate 66 to the tip of the suction duct 96 of the first cleaning unit 7.

  When the cutting unit 6 is performing the cutting operation, the second cleaning unit 8 is in a non-cleaning posture F that is not in contact with the groove bottom surface 10. In this non-cleaning posture F, the arm member 181, that is, the second cleaning unit 8 is moved upward around the support shaft member 183 when the large curvature portion 90 or the small curvature portion 91 of the elevating cam 87 contacts the outer peripheral surface of the cam roller 95. The non-cleaning posture F is maintained by rotating counterclockwise so as to move.

[Cleaning operation of the cutout part 6 by the first cleaning part 7] After the powdered medicine 5 in the annular groove 4 is cut out over the entire circumferential direction of the annular groove 4 as described above, FIG. As shown in the figure, the cutout portion 6 is set to the separation posture B, and the first cleaning portion 7 is changed from the non-cleaning posture E to the cleaning posture C to remove and clean the powder 5 adhered to the cutout portion 6.
As described above, the first cleaning unit 7 (suction duct 96) is constantly biased to the non-cleaning posture E by the spring body 39. In order to change the first cleaning unit 7 from the non-cleaning posture E to the cleaning posture C, the lifting / lowering motor 85 is driven to rotate the lifting / lowering cam 87 clockwise around the lifting / lowering horizontal shaft 86, as shown in FIG. 7, the cam pin 97 is brought into contact with the outer peripheral surface of the duct cam roller 92. Then, the duct cam roller 92 rotates about the horizontal axis 92a and the duct cam roller 92 is kicked by the cam pin 97 and moves in the moving direction of the cam pin 97, so that the front link member 135 resists the elasticity of the spring body 39 and is moved to the previous time. The front link member 135 rotates counterclockwise around the moving central axis 137, and the front link member 135 is relative to the vertical axis as compared with a state where the cam pin 97 is not in contact with the duct cam roller 92 (corresponding to the non-cleaning posture E). And lean greatly.

  That is, as the rotation pin member 150 moves forward (radially outward) and the rotation pin member 151 moves forward as the rotation pin member 150 moves, the rear link member 136 moves backward. The suction duct 96 attached to the rotation pin members 150 and 151 via the extension bracket 106 moves forward while maintaining the horizontal state. Thus, the first cleaning portion 7 changes from the non-cleaning posture E to the cleaning posture C in which the first removal brush 124 of the first cleaning portion 7 can contact the cutout portion 6.

At this time, the cut-out portion 6 has already been turned upward (counterclockwise) about the support shaft member 183 to be in the separated posture B, and is approaching the first cleaning portion 7 side, and the first cleaning portion Since 7 moves forward, the first removal brush 124 of the first cleaning unit 7 can come into contact with the partition plate 30, the cut plate 31 and the plate surface of the cover body 31A of the cut unit 6, respectively. In FIG. 7, the distance Y2 from the flat plate 68 of the blocking plate 66 to the tip of the suction duct 96 of the first cleaning unit 7 is expressed as Y2> Y1.
In addition, by using the parallel link mechanism as a mechanism for changing the posture of the suction duct 96, the amount of vertical movement when the suction duct 96 changes its posture can be minimized.

  In the embodiment of the present invention, when the cut-out portion 6 is in the separation posture B, the cut-out plate 31 is cut out so that the tip end portion of the tip plate portion 48 of the cut-out plate 31 is in the duct suction port 107 as shown in FIG. The plate 31 is controlled to rotate around the rotation transmission shaft 60. In this state, the attachment support 54 side of the cutout plate 31 is disposed so as to be inclined downward (toward the radial direction). Further, by turning the cutout plate 31 around the rotation transmission shaft 60 to such a position, the cutout plate 31 has an inclination angle substantially equal to the inclined plate 79. Further, the cutout plate 31 is disposed at a position facing the front side of the blocking plate 66. Thus, the position of the cutout plate 31 that the cutout plate 31 is rotated around the rotation transmission shaft 60 so that the front end portion of the front end plate portion 48 of the cutout plate 31 is at the duct suction port 107 corresponds to a predetermined position. To do.

  Therefore, the partition plate 30, the cutout plate 31, the cover body 31 </ b> A, the blocking plate 66, and the bottom wall 102 of the suction duct 96 serve as walls, and a space Z that is surrounded by these walls and communicates with the duct suction port 107 is formed. Will be. After forming such a space Z, the cleaning air 134 is sprayed from the spray nozzle 98 toward the diagonally upward direction from the spray hole 132 against the plate surface of the cutout plate 31, particularly the tip plate portion 48. At the same time, air in the suction duct 96 is sucked from the suction hose 100 (discharge hole 131).

  Thus, by blowing out the cleaning air 134 from the spray nozzle 98, the powder 5 adhering to the cutting plate 31, particularly the plate surface of the tip plate portion 48 is removed by the cutting operation, and the partition plate 30 and the cutting plate 30 are cut out. The remaining medicine of the powdered powder 5 at the mounting corner with the plate 31 and the mounting corner between the cut-out plate 31 and the cover body 31 </ b> A is removed, and the air in the suction duct 96 is sucked from the suction hose 100. The air containing the powdered powder 5 becomes negative pressure, moves into the suction duct 96, and is sucked toward a predetermined place by the suction hose 100.

  Thus, a space Z surrounded by the partition plate 30, the cutout plate 31, the cover body 31A, the blocking plate 66 and the bottom wall 102 of the suction duct 96 is formed, and the partition plate 30 and the cover body 31A are used as vertical walls. The cleaning air 134 is blown to the outlet plate 31 obliquely from below, and the cutting portion 6, particularly the corners where the cutting plate 31, the partition plate 30 and the cutting plate 31 are attached, and the cutting plate 31 and the cover body 31A. The remaining medicine of the powder 5 at the mounting corner is removed in the space Z, and after the powder removal including the powder 5 in the space Z is introduced into the suction duct 97 from the duct suction port 107, The suction hose 100 connected to the bottom wall 102 is used for suction. Accordingly, the flow of the air 134A after the powder removal is generated within the limited range of the space Z to make it difficult for the air to flow to the outside. In this state, the powder 5 attached to the cut-out portion 6 is removed from the duct suction port 107. It can be processed reliably.

  By the way, after the cutting operation is completed, it is considered that the powder 5 is also attached to the plate surfaces of the partition plate 30 and the cover body 31 </ b> A in the cutting portion 6. The powder 5 may be removed by the ejection of the cleaning air 134, but the cleaning air 134 is configured to blow against the cutting plate 31, and thus is difficult to remove by the cleaning air 134. . Therefore, the powder 5 adhering to the plate surfaces of the partition plate 30 and the cover body 31 </ b> A is mainly removed by the first removal brush 124.

  In the first removal brush 124, the two bundles of first removal brushes 124b on the downstream side in the circumferential direction are on the partition plate 30 side and are arranged to be inclined toward the downstream side with respect to the plate surface of the partition plate 30. The brush of the first removal brush 124b comes into contact with the plate surface of the partition plate 30 while being inclined. Further, the two bundles of the first removal brushes 124c on the downstream side in the circumferential direction are disposed on the cover body 31A side so as to be inclined toward the upstream side with respect to the plate surface of the cover body 31A. Is in contact with the plate surface of the cover body 31A while being inclined.

  Accordingly, by rotating the partition plate 30 and the cover body 31A around the rotation transmission shaft 60 (counterclockwise), the first removal brush 124b and the first removal brush 124c are inclined by an amount corresponding to the inclination. Since each plate surface of the body 31A comes into strong and reliable contact, the powder 5 adhering to the respective plate surfaces of the partition plate 30 and the cover body 31A can be reliably removed.

  Since the duct suction port 107 is below the first removal brush 124, the suction hose 100 sucks air in the suction duct 96 while rotating the partition plate 30 and the cover body 31 </ b> A around the rotation transmission shaft 60. The powder 5 removed by the first removal brush 124b and the first removal brush 124c is also sucked toward a predetermined place. In addition, since the 1st removal brush 124a arrange | positioned in the center of the circumferential direction is arrange | positioned in parallel with the plate surface of the partition plate 30 and the cover body 31A, and contacts the cutting plate 31, the powder 5 adhering to the cutting plate 31 is the It is more reliably removed and sucked by the suction hose 100.

  Further, when cleaning the powder 5 adhering to the cut-out portion 6 as described above, since the blocking plate 66 is present when the cleaning air 134 is ejected, the post-powder removal air 134A containing the powder 5 can be used in various ways. Since it is difficult to reach the inside of the rotating plate 22 in the radial direction, which is a place where the mechanical device is disposed, it is possible to suppress the powder 5 from adhering to the mechanical device.

  When the elevating cam 87 is rotated clockwise around the elevating horizontal axis 86 and the cam pin 97 is detached from the duct cam roller 92, there is no need to operate the duct cam roller 92. The first cleaning unit 7 returns from the cleaning posture C to the non-cleaning posture E again.

As described above, the cam roller 94 is provided on the cutout portion 6 side, the link mechanism constituted by the plate-like link member is provided on the first cleaning portion 7 side, the duct cam roller 92 is provided on the link mechanism, and the cam roller 94 and An elevating cam 87 or a cam pin 97 that can come into contact with the duct cam roller 92 is provided on the elevating cam 87 so that the postures of the cutout portion 6 and the first cleaning portion 7 are switched in conjunction with the rotation of the elevating cam 87. ing.
That is, since the cut-out portion 6 and the first cleaning portion 7 having different functions are configured to change the posture with a common member called the lifting cam 87, the operation of the cut-out portion 6 and the first cleaning portion 7 is changed. Therefore, it can be made compact compared with the case where the mechanism for this is a separate mechanism.

[Cleaning operation of groove bottom surface 10 by second cleaning unit 8]
While the powder 5 adhering to the cut-out portion 6 is removed by the first cleaning unit 7, the powder 5 adhering to the groove bottom surface 10 after the cut-out operation is finished is removed by the second cleaning unit 8. While the cutting unit 6 is performing the cutting operation, the second cleaning unit 8 is in the non-cleaning posture F that is not in contact with the groove bottom surface 10. 8 is brought into contact with the groove bottom surface 10.

  In order to set the second cleaning unit 8 to the cleaning posture D, the lifting motor 85 is driven and the lifting cam 87 is rotated clockwise around the lifting shaft 86, for example, FIGS. As shown in FIG. 12, the elevation cam 87 and the cam roller 95 are brought into non-contact with each other by making the plane portion 88 of the elevation cam 87 face the cam roller 95, and the second cleaning portion 8 is watched by its own weight around the support shaft member 183. Rotate in the direction. By doing in this way, the 2nd cleaning part 8 becomes the cleaning posture D.

Here, when the rotation drive motor 158 is driven and the rotation center shaft 157 is rotated counterclockwise around its axis, the rotation center plate 155 and the rotation center body 160 rotate around the rotation center axis 157. The powder 5 on the groove bottom surface 10 is swept out in the radial direction of the rotating plate 22 by the brush body 153 in contact with the groove bottom surface 10 and wiped by the wiping body 156 in contact with the groove bottom surface 10. When the powder 5 is removed by the second cleaning unit 8, the rotating plate 22 is rotated about the vertical axis 2 in the opposite direction (counterclockwise direction indicated by the arrow in FIG. 9) when supplying the powder 5 to the groove 24. .
By rotating the rotating plate 22 in this direction, the powder 5 remaining on the groove bottom surface 10 is first removed by the brush body 153, and the remaining powder 5 is still wiped by the wiping body 156 reliably. Removed.

The rotary wiping body 154 is provided as a separate body from the brush body 153 so as to be adjacent to the brush body 153 on one side in the axial direction of the rotation center shaft 157, and a set of cleaning parts includes the rotary wiping body 154 and the brush body 153. It has a structure.
However, it is also possible to make a plurality of combinations of the rotary wiping body and the brush body in the order of the rotational wiping body, the brush body, the rotational wiping body, and the brush body from the back plate 165 side. Alternatively, a cloth body having the same diameter as that of the rotary wiping body 154 can be provided at the center of the brush body 153 in the front-rear direction (width direction of the rotation center body 160).
In such a configuration, the rotational wiping body 154 and the brush body 153 have a complicated configuration as compared with a case where a set of cleaning partial structures is configured, but the cleaning ability is improved as compared with a set of cleaning partial structures. .

  Further, simultaneously with the removal of the second removal brush 161 from the groove bottom surface 10, the suction pump (not shown) is driven, so that the air 134B after powder removal including the powder 5 is introduced from the suction port 172 into the introduction pipe. Aspirate to 171. At this time, the lower surface 174 of the inclined surface 173 is extended downward, and in the cleaning posture D of the second cleaning unit 8, the virtual extension obtained by extending the groove bottom surface 10 of the annular groove 4 of the rotating plate 22 with its curvature. Since it is formed to converge near the line 10b, the powdered powder 5 after being removed is guided to the suction port 172 side together with the air 134B after the powder is removed and introduced into the joint pipe portion 170 from the suction port 172. Of the inner peripheral surface of the joint pipe portion 170 to be formed, the region on the second cleaning portion 8 side is formed as an inclined surface 173 so as to increase in diameter toward the front lower side and the brush body 153 side. Therefore, the air 134B after powder removal is smoothly sucked from the suction port 172 along the inclined surface 173.

  Further, the suction port 172 is not extended in the protruding direction of the second removal brush 161, but is open to the back plate 165 outside the radial direction of the second removal brush 161. That is, the suction port 172 is opened in the direction orthogonal to the plane including the second removal brush 161 at the same position in the front-rear direction in each second brush group 163 between the apex sides 162. When the suction port 172 is disposed in the projecting direction extension of the second removal brush 161 and the suction port 172 is disposed on a plane including the second removal brush 161 at the same position in the front-rear direction, the second removal from the suction port 172 is performed. Although the distance from the predetermined position in the radial direction of the brush 161 to the suction port 172 varies greatly, by forming the suction port 172 in the protruding plate portion 168 of the back plate 165 of the covering 164, the second removal brush 161 A suction force acts on the second removal brush 161 from the side, and a change in the distance from the predetermined position in the radial direction of the second removal brush 161 to the suction port 172 is suppressed from the suction port 172. Since the suction force from the mouth 172 is uniform over the radial direction of the second removal brush 161, even if the powder 5 is attached to the second removal brush 161, the powder 5 Easily drawn over the radiation length direction of the two-removing brush 161.

  In addition, since the brush body 153 and the rotary wiping body 154 are integrated with a separate end cap 64, the brush body 153 can be handled separately by removing the end cap 64. Even when the life of the rotary wiping body 154 is different, it can be replaced separately.

  When the second cleaning unit 8 is in the cleaning posture D, the brush body 153 and the rotating wiping body 154 are covered with the covering body 164 and the rotating plate 22, and a space region substantially closed by the covering body 164 and the rotating plate 22 is formed. The upper open portion of the groove member 25 is covered with the cover 164 and the rotating plate 22. Therefore, by rotating the brush body 153, the removed powder 5 is prevented from leaking to the outside, and is processed in the closed space region.

  When the rotary plate 22 is rotated around the vertical axis 2, the groove member 25 fixed to the upper surface of the flat plate portion 23 of the rotary plate 22 also rotates around the vertical axis 2. Then, the suction nozzle 49 stays in the groove member 25 without being moved by the suction nozzle 49 in synchronization with the driving of the rotary plate 22 around the vertical axis 2, that is, in synchronization with the cleaning operation of the second cleaning unit 8. The powdered powder 5 can be discharged by sucking.

  As described above, according to the embodiment of the present invention, the remaining powder 5 can be reliably removed by the first cleaning unit 7 and the second cleaning unit 8. Contamination can be suppressed even when different types of powders 5 are handled.

  The packaging device includes a cutting section for cutting the granular material supplied along the annular concave groove of the rotary table by a predetermined area in the radial direction of the rotary table, and the cutting section It is also possible to configure so as to include a discharging unit that discharges air toward the cutting part. According to this structure, the granular material adhering to the cut-out part is removed by cleaning by discharging air from the discharge part toward the cut-out part.

  In addition, the packaging device can be configured such that a suction unit that sucks dust removed by the air discharged from the discharge unit is provided. In such a configuration, the granular material cleaned and removed by the air discharged from the discharge portion is sucked by the suction portion.

  Further, the packaging device includes a rotary table that is rotatable about the vertical axis, and a granular material supplied along the annular groove on the rotary table for each predetermined region in the circumferential direction of the annular groove. And a cutting device for cutting out the granular material cut out by the cutting portion, wherein the cutting portion is located above the annular groove. A cutting plate rotatable around a certain horizontal axis, and a vertical wall arranged in parallel so as to be concentric with the cutting plate on each of one circumferential side and the other circumferential side of the cutting plate, A discharge part for discharging cleaning air for removing the powder particles adhering to the outlet part and a suction part for sucking the powder particles removed by the cleaning air from the cut-out part are provided, and the discharge When the cutout plate is positioned at a predetermined position around the horizontal axis, the cleaning air from the section is Wherein is the wall which is provided in the suction portion can eject respect space surrounded by, it is also possible to suction port provided on the suction unit is configured as being open to the space.

In the above configuration, the granular material is supplied to the annular groove on the rotary table, the cut plate of the cut portion is rotated around the horizontal axis above the annular groove, and the circumference of the annular groove is formed by the vertical wall. The granular material is cut out in the radial direction of the annular groove while regulating the granular material in the predetermined direction, and then the rotary table is rotated by a predetermined angle around the vertical axis and stopped, and the cutting plate is rotated around the horizontal axis. Rotate to cut out the next granular material in the predetermined circumferential direction, and sequentially cut out the granular material.
As described above, the cutting plate of the cutting part is rotated, and the granular material adhering to the cutting part is removed by cutting out the granular material while regulating the granular material in the circumferential direction predetermined region by the vertical wall. In this case, the cutting plate is rotated to a predetermined position around the horizontal axis to form a space surrounded by the cutting plate, both vertical walls, and the wall surface provided in the suction unit, and then the cleaning air is discharged from the discharge unit. And the air in the space is sucked from the suction port of the suction part, so that it is difficult for the air to escape from the space to the outside, and thus the granular material removed by the cleaning air discharged from the discharge part is space. It is possible to make the powder particles removed by the cleaning air sucked together with the air in the space and reliably discharged. That is, the cleaning air discharged into the space collides with the cut-out part, so that the powder particles adhering to the cut-out part are removed from the cut-out part and drifted into the space, together with the air in the space. Clean by suction from the suction port of the suction part. Therefore, contamination can be prevented even when different types of granular materials are handled in a single packaging device.

  Further, in the packaging device, the cutting part is divided into a cutting posture in which the cutting plate comes into contact with the annular groove and the powder plate is cut out, and a separating posture in which the cutting plate is spaced upward from the annular groove. An operation unit that operates the cutout part so as to switch the posture of the cutout plate is provided, and a space is formed when the cutout plate is operated by the operation unit so that the cutout plate is in the separated posture. It can also be configured to be.

  In the above configuration, when cleaning the cutout part, the cleaning air is supplied from the discharge part to the space formed by changing the cutout plate from the cutout position to the separated position by operating the operation unit. And the air in the space containing the particulates is sucked from the suction port of the suction part.

  Furthermore, in the packaging device, the vertical wall on one side is a partition plate that rotates about the axis above the annular groove, and the vertical wall on the other side is the axis that is above the annular groove with the cutout plate. It can also be configured to be a cover body that rotates around and covers the cut-out plate on its side.

  In the above configuration, the granular material in the circumferential predetermined region is cut out by being partitioned by the partition plate and the cover body. Therefore, after the cutting is finished, the granular material attached to the wall surface of the partition plate and the cover body is in the space. The cleaning air collides with the wall surface by causing the cleaning air to be discharged to remove the granular material, and the removed granular material is sucked from the suction port of the suction portion.
