Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tablet conveyance device with a tablet posture alignment function and a tablet dividing device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, hospitals and dispensing pharmacies provide divided tablets when providing tablets to patients based on prescriptions, in the case of prescription that is excessive with one tablet or when it is difficult to drink.
[0003]
In this case, the simplest method for dividing one tablet is to cut the tablet manually. For this reason, there is a tablet in which a dividing groove for division is formed in advance. A tablet cutter as shown in Japanese Utility Model Publication No. 6-41546 has also been proposed.
[0004]
However, since manual operation is inefficient, automatic dividing machines such as Japanese Utility Model Laid-Open No. 3-114241 and Japanese Patent Laid-Open No. 2-29257 have been proposed.
[0005]
However, this dividing machine is a mechanism that sandwiches the tablets from the left and right by opposing belts and conveys the tablets to the position of the rotary cutter (or thin blade cutter operated up and down). It cuts like this. This automatic dividing machine seems to be exclusively for circular tablets, and is not considered for tablets with an elliptical shape (or an oval cross section). For example, in the case of an elliptical tablet, it may be cut as shown in FIG.
[0006]
That is, in the case of such an elliptical tablet, since it cannot be stably held between the left and right belts, the longitudinal direction of the tablet being conveyed does not become constant. Therefore, the positional relationship between the tablet conveyed to the cutter and the cutter is not uniquely determined, and even when, for example, it is cut equally, it cannot be cut equally.
[0007]
[Problems to be solved by the invention]
The present application proposes a tablet conveying device and a tablet dividing device with a tablet posture alignment function for aligning the posture of a tablet and conveying the tablet so that the tablet is cut as shown in FIG.
[0008]
Further, a mechanism for tablet inspection has been proposed as a mechanism for transporting the tablets with their postures aligned to a predetermined position (for example, JP-A-7-201644). However, since this uses a belt conveyor, it is suitable for a large-scale apparatus for factories, but is not suitable for an automatic dividing apparatus for dispensing pharmacies.
[0009]
This application provides the apparatus suitable for the automatic dividing apparatus for dispensing pharmacies. That is, the present invention provides a tablet conveying device and a tablet dividing device that align the posture of the tablet and convey it to the cut position regardless of the shape of the tablet.
[0010]
[Means for Solving the Problems]
The present invention provides a tablet dividing machine that divides a tablet to be processed at a predetermined position, a blade for cutting the tablet to be processed, a tablet case that supplies the tablet, and a tablet that is dropped and supplied from the tablet case. Alignment means for aligning the longitudinal direction of the tablets to be processed so as to be orthogonal to the moving direction by moving the distance, a slope for dropping the tablets to be processed aligned by the alignment means, and dropping the slope The tablet to be processed is received with respect to the blade by sandwiching the tablet to be processed, which is received by the processed tablet, and aligning the tablet to be processed from the longitudinal direction. Clamping means for aligning the positions of
It comprises a conveying means for conveying the processed tablet aligned by the clamping means to a cutting position, and a posture changing plate provided in the dropping path of the tablet dropped from the tablet case. And
[0011]
The present invention also includes a blade for cutting the tablet to be processed, and an aligning means for aligning the longitudinal direction of the tablet to be processed perpendicularly to the moving direction by moving the tablet to be processed by a predetermined distance. An inclined surface for dropping the tablets to be processed that are aligned by the aligning means, a shutter means for receiving the tablets to be processed that have fallen on the inclined surfaces, and aligning the tablets to be processed; By holding the tablet to be processed from the longitudinal direction, the holding means for aligning the position of the tablet to be processed with respect to the blade, and the tablet to be processed aligned by the holding means are conveyed to the cutting position. A tablet dividing apparatus comprising: a conveying unit; and a range of positions where the clamping unit functions as a guide for the tablet to be processed before the conveying unit is driven. In characterized by expansion.

[0014]
In FIG. 11, reference numeral 100 denotes a tablet case containing a tablet, which is attached to a tablet feeder (described later).
[0015]
The configuration of the present application will be described with reference to FIGS. 1 to 4 with the cover removed.
[0016]
The tablet dividing machine 1 of the embodiment basically has a box shape composed of three side walls 2, 3, 4, a bottom wall 6 and a top wall 7, and a tablet feeder 8 is attached on the top wall 7. ing.
[0017]
Arc-shaped passage walls 12 and 13 are provided on a horizontal plate 11 installed below the top wall 7. These passage walls 12 and 13 are arranged with a space between each other with the center of each arc being the same, and an arcuate passage 14 is defined between them. One end portion (right end portion) of the passage 14 corresponds to the lower side of the baffle plate 9 provided below the chute portion of the tablet feeder 8, and the other end portion extends between the side walls 2 and 3. Yes. The baffle plate 9 may be omitted.
[0018]
Reference numeral 16 denotes a rotating arm driven by a rotating arm motor 17 attached to the lower surface of the horizontal plate 11, and the center of rotation is the same as the center of the arc of the passage walls 12 and 13. The rotary arm 16 includes a pressing plate 16A having an area substantially equal to the cross-sectional area of the passage 14 and movably disposed in the passage 14. The rotary arm 16 is rotated by the rotary arm motor 17 and thereby pressed. The plate 16A moves in the passage 14 from one end portion to the other end portion at a predetermined speed.
[0019]
Reference numeral 18 denotes a slope plate (posture correction means) provided continuously at the other end of the passage 14, and is provided between the side walls 2 and 3 so as to be inclined lower toward the front side. A baffle plate 19 is attached in the passage 14 between the slope plate 18 and the baffle plate 9. The baffle plate 19 is rotatably attached to the outer passage wall 12 and protrudes from the passage wall 12 toward the center of the arc of the passage wall 12. The baffle plate 19 is made of a deformable elastic material. These passage walls 12 and 13, the passage 14, the rotating arm 16, the baffle plate 19, and the like constitute an alignment means. The baffle plate 19 is made of, for example, an iron plate that is rotatably attached to the passage wall 12, and is urged and supported toward the center of the arc of the passage wall 12 by a biasing means such as a spring. But it doesn't matter.
[0020]
At the lower end of the inclined plate 18, a holding spring (plate spring) 21 is provided which is continuously bent at the same inclination and is smoothly bent in the horizontal direction, and is attached between the side walls 2 and 3. A shutter 22 is disposed on the holding spring 21, and further, a holding roller (rotating roller) 23 is rotatably supported between the side walls 2 and 3 below and slightly held below the shutter 22. It is located on the spring 21 for use.
[0021]
The shutter 22 is connected to a shutter motor 24 attached to the outside of the side wall 2 via crank plates 26 and 27. When the shutter motor 24 rotates, the shutter 22 is moved up and down by a crank mechanism formed by the crank plates 26 and 27. Moved.
[0022]
The holding roller 23 is connected to a roller motor 31 attached to the outside of the side wall 2 via a small pulley 32, a large pulley 33 and a belt 34, and the roller motor 31 rotates to reduce the speed. 4 is rotated clockwise in FIG. The holding roller 23 and the holding spring 21 constitute a conveying unit.
[0023]
Reference numeral 36 denotes a rotary blade disposed below the holding roller 23 and the holding spring 21. The rotary blade 36 is attached to a rotary shaft of a rotary blade motor 37 attached to the outside of the side wall 2 by a fixture 38 and is disposed corresponding to the lower center of the side wall 2 and the side wall 3. Rotates counterclockwise in FIG.
[0024]
In this case, grooves 23A and 21A are formed in the central portions of the holding roller 23 and the holding spring 21 at positions overlapping vertically, and the upper part of the rotary blade 36 passes through the grooves 21A and 23A. It has entered into the holding roller 23. Therefore, the rotary blade 36 does not hit the holding spring 21 or the holding roller 23. Reference numeral 54 denotes a tray that is disposed below the rotary blade 36.
[0025]
On the other hand, a pair of clamping plates 41 and 42 (clamping means) are arranged on the left and right on the slope plate 18 and the holding spring 21 in the subsequent portion. The sandwiching plates 41 and 42 are fixed to slide plates 43 and 44, respectively, and the slide plates 43 and 44 are held between the substrate 46 and the left and right pressing plates 47 and 48 so as to be movable in the left-right direction. At this time, the sandwiching plates 41 and 42 are located on the back side of the substrate 46, and the slide plates 43 and 44 are located on the front side of the substrate 46. And both are connected in the notches 46A and 46A formed in the board | substrate 46. FIG.
[0026]
Pins 43 </ b> A and 44 </ b> A are erected on the left end toward the slide plates 43 and 44, and the pins 43 </ b> A and 44 </ b> A are rods 52 attached to the rotating shaft of the clamping plate motor 51 attached to the back surface of the substrate 46. It is engaged with grooves 52A and 52B at both ends so as to be rotatable and movable. A clamping mechanism 53 is constituted by the clamping plates 41 and 42, the slide plates 43 and 44, the substrate 46, the pressing plates 47 and 48, the clamping plate motor 51, the rod 52, and the like.
[0027]
With this configuration, when the clamping plate motor 51 rotates and the rod 52 rotates clockwise in FIG. 6, the slide plate 43 moves to the right in FIG. 6, and the slide plate 44 moves to the left in the opposite direction. The sandwiching plates 41 and 42 move so as to be separated from each other. Conversely, when the clamping plate motor 51 rotates in the reverse direction and the rod 52 rotates counterclockwise in FIG. 6, the slide plate 43 moves to the left in FIG. 6, and the slide plate 44 moves to the right in FIG. The sandwiching plates 41 and 42 move so as to be close to each other. However, it is assumed that the center position between the sandwiching plates 41 and 42 always coincides with the center between the side walls 2 and 3.
[0028]
The rotary arm motor 17, the shutter motor 24, the roller motor 31, and the clamping plate motor 51 are configured by stepping motors, and the rotary blade motor 37 is configured by a DC motor, all of which are controlled by a control device (not shown). Shall be controlled.
[0029]
Next, the operation of the above configuration will be described. In this case, if the oval (or oval) tablets are discharged one by one from the chute portion of the tablet feeder 8, the discharged tablets (processed tablets) M hit the baffle plate 9 and change its direction, and the path Fall into 14. The control device drives the rotary arm motor 17 to rotate the rotary arm 16 counterclockwise in FIG. 3 (arrow in FIG. 3).
[0030]
Thereby, the pressing plate 16A of the rotating arm 16 pushes the dropped tablet M against the baffle plate 19 and moves it. Due to the pressing force of the pressing plate 16A, the posture of the tablet M changes along the surface of the pressing plate 16A, and the longitudinal direction thereof becomes a direction orthogonal to the moving direction.
[0031]
When the tablet M is next pressed against the baffle plate 19 by being pushed by the push plate 16A in this way, the baffle plate 19 is deformed while opening from the tip due to its elasticity, and an oblique force is applied to the tablet M as a reaction force. . Since the rotational moment is generated by the sum of the vectors of the force from the baffle plate 19 and the pressing force of the pressing plate 16A, the posture of the tablet M is further aligned so that its longitudinal direction is orthogonal to the moving direction. become.
[0032]
The tablet M that has passed through the baffle plate 19 eventually reaches the slope plate 18 and slides there. During the sliding process, the posture of the tablet M is surely perpendicular to the dropping direction.
[0033]
At this time, since the sandwiching plates 41 and 42 are separated from each other, the tablet M slides between the sandwiching plates 41 and 42. Further, the rotating arm 16 is then rotated clockwise in FIG. 3 and returned to a predetermined standby position. Further, since the shutter 22 is lowered, the tablet M that has slid down the inclined plate 18 is blocked by the shutter 22.
[0034]
In the state of being dammed by the shutter 22, the center position of the tablet M does not always coincide with the center between the side walls 2 and 3. Therefore, the control device first drives the shutter motor 24 to raise the shutter 22 by the crank plates 26 and 27. Next, the clamping plate motor 51 is driven to move the clamping plates 41 and 42 so as to be close to each other as described above. When the sandwiching plates 41 and 42 move, the tablet M finally comes into contact with any one of the sandwiching plates 41 or 42, and when the center thereof coincides with the center of the side walls 2 and 3, both ends in the longitudinal direction of the tablet M are sandwiched between the sandwiching plates 41 and 42. It is pinched by 41 and 42.
[0035]
In this state, the posture of the tablet M is surely positioned on the center of the side walls 2 and 3, that is, on the extended line of the rotary blade 36, with the longitudinal direction orthogonal to the moving direction. .
[0036]
Next, the control device slowly rotates the holding roller 23 by the roller motor 31 (at this time, the rotary blade 36 is rotating), and separates both the sandwiching plates 41 and 42 by the sandwiching plate motor 51.
[0037]
As a result, the tablet M reaches the holding roller 23 and slowly moves in the left direction in FIG. 4, that is, in the direction of the rotary blade 36 while being elastically sandwiched between the holding roller 23 and the holding spring 21. It is conveyed. Since the center of the tablet M reaching the rotary blade 36 is aligned with the position of the rotary blade 36, the center is cut and accurately divided into two. Then, the divided tablet is further fed out by the holding roller 23 and falls into the tray 54.
[0038]
The thickness of the tablet M at this time is absorbed by the holding spring 21 being deformed downward. Further, the rotary blade 36 rotates in the grooves 21A and 23A and is cut by the rotary blade 36 while being pressed against the holding roller 23. Therefore, the force at that time is not the holding spring 21 but the holding roller 23. Will join.
[0039]
As described above, according to the present invention, the longitudinal direction of the tablet M is aligned so as to be orthogonal to the moving direction by moving the arc-shaped passage 14 with the rotary arm 16, and in this state, the clamping plate After being sandwiched by 41 and 42 from the longitudinal direction and aligning the center of the tablet M with the rotary blade 36, the tablet M is conveyed to the rotary blade 36 by the holding roller 23 and cut. Therefore, the position and posture of the tablet M with respect to the rotary blade 36 when it is conveyed to the rotary blade 36 can be uniquely determined even if the tablet has a shape other than a circle such as an elliptical or oval tablet.
[0040]
Further, since the rotary blade 36 can cut the tablet M safely and reliably as compared with the push-cut type cutter, the tablet M can be accurately divided regardless of its shape. .
[0041]
In particular, since the inclined plate 18 is dropped and the posture is corrected so that the longitudinal direction of the tablet M is orthogonal to the dropping direction, the longitudinal direction of the tablet M is orthogonal to the moving direction when it exits the passage 14. Even when it cannot be made, the posture of the tablet M can be reliably corrected.
[0042]
Further, the tablet M is sandwiched between the holding roller 23 and the holding spring 21 and conveyed to the rotary blade 36, and the force applied to the tablet M at the time of cutting by the rotary blade 36 acts on the holding roller 23. Since the relative position between the rotary blade 36 and the holding roller 23 and the rotation direction of the rotary blade 36 are set, excessive force is not applied to the tablet M or the rotary blade 36.
[0043]
In the above embodiment, the clamping plates 41 and 42 are driven to approach and separate by the crank structure formed by the engagement between the pins 43A and 44A of the slide plates 43 and 44 and the rod 52. As shown in FIG. 9, a belt 66 spanned between a pulley 66 attached to the rotating shaft of the sandwiching plate motor 51 and a pulley 67 on its side is provided on the left and right sides of the substrate 46 and connected to the forward path of the reciprocating belt 61. The slide plate 43 may be fixed via the plate 62, and the slide plate 44 may be fixed to the return path via the connecting plate 63. In addition, in each figure, the thing of the same code | symbol as FIGS. 1-7 is the same.
[0044]
Even with such a structure, the forward and backward paths of the belt 61 can be moved in opposite directions by forward and reverse rotation of the clamping plate motor 51, and the same operation as described above can be applied to the slide plates 43 and 44. Further, the same operation can be realized by a gear, for example, without using the belt drive. In this embodiment, the substrate 46 is substantially upright because the distance dimension of the inclined plate 18 is shorter than that of the above-described embodiment. Thus, the fall distance of the tablet M can be shortened by shortening the dropping path of the inclined plate 18.
[0045]
In the embodiment, the case of dividing an elliptical tablet has been described, but it goes without saying that even in the case of a normal circular tablet, it can be equally divided into two at the center.
[0046]
Next, an embodiment in which the baffle plate 19 is made of an iron plate will be described with reference to FIGS. In the figure, the same components as those in FIGS.
[0047]
In FIG. 12, 19 ′ is a baffle plate that is biased and supported toward the center of the arc of the passage wall 12 by a spring (not shown). The baffle plate 19 ′ is rotatably attached to the passage wall 12 side and is urged and supported toward the center of the arc of the passage wall 12.
[0048]
Reference numeral 16 'denotes a rotating arm. 16A ′ is a push plate. Reference numeral 16B ′ denotes a baffle plate regulating lever.
[0049]
Reference numeral 23 'denotes a holding roller. As shown in FIG. 13, a part of the holding roller 23 ′ is formed with irregularities on the rubber roller surface. And it is comprised so that the unevenness | corrugation of the right and left both sides of groove | channel 23A 'may become object. Although this unevenness has a function of holding the tablet firmly, the first purpose of this embodiment is not.
[0050]
That is, when the roller 23 of the embodiment of FIG. 2 is rotated, the tablet is transported, but at this time, the rollers on both the left and right sides of the groove 23A do not necessarily start transporting the tablet at the same timing. Occasionally, if the conveyance by one roller side is fast, the tablet is inclined.
[0051]
In the embodiment of FIG. 13, the unevenness is configured for the left and right objects. Therefore, the possibility that the rollers on the left and right sides of the groove 23A ′ start to transport the tablets at the same timing is increased.
[0052]
The operation of FIGS. 12 to 17 will be described.
[0053]
First, when a split operation is performed, the rotary arm 16 and the clamping plates 41 and 42 are set to the initial positions.
[0054]
First, one tablet is discharged from the tablet feeder.
[0055]
The rotary arm motor 17 is driven, and the push plate 16A ′ pushes the tablet M.
[0056]
And FIG. As shown in FIG. 15, the tablet M hits the baffle plate 19 ′. And the long side of the tablet M comes along the surface of the pressing plate 16.
[0057]
As shown in FIG. 16, the tablet M slides down the slope plate 18 and comes into contact with the shutter 22 and stops. At this time, the return of the baffle plate 19 ′ to the original position is restricted by the restriction lever 16B ′ until the push plate 16A returns to the original position.
[0058]
The function of the slope plate 18 will be described with reference to FIG. As shown to a and b of FIG. 17, the tablet M slides down. Here, there is a possibility that the tablet stands as shown in FIG. At this time, the tablet M can be laid as shown in c and d of FIG.
[0059]
Next, the function of the shutter 22 will be described.
[0060]
The tablet M slides down the slope 18 and the leaf spring 21. At this time, the posture of the tablet M may be inclined. Then, if it strikes the roller 23 'with this tilt, it may bite into the roller 23' with the tilted posture.
[0061]
Therefore, a shutter 22 is provided. Since the long side of the tablet M is along the surface of the shutter 22 by the shutter 22, even if the posture of the tablet M is tilted, it is corrected.
[0062]
Thereafter, the shutter 22 is opened, and the tablet M is dropped to the contact position of the roller 23 '. Since the drop distance at this time is short, the tablet M does not bite into the roller 23 '.
[0063]
Next, the clamping plates 41 and 42 move in the center direction (E direction in FIG. 16), and the center of the tablet M and the position of the rotary blade 36 are aligned.
[0064]
Next, the roller 23 ′ is driven, and the tablet is held by the roller 23 ′ and the holding spring 21.
[0065]
Immediately thereafter, the sandwiching plates 41 and 42 are expanded (in the direction opposite to E in FIG. 16) to return to the initial position.
[0066]
Then, the tablet M is conveyed by the roller 23 ′ and cut by the rotary blade 36. At the time of this cutting, the force by the rotary blade 36 acts not on the holding spring 21 but on the roller 23 'side, so that the holding force of the tablet M by the roller 23' and the holding spring 21 does not decrease even during rotation. Stabilize.
[0067]
Moreover, in the said Example, although the tablet M was cut with the rotary blade 36, you may divide | segment with the cutter (guillotine cutter) which moves up and down separately. In short, it is important to transport the tablets in a predetermined posture to the cutting position. Even if the tablets transported to the cutting position are cut with a rotary blade, they are cut with a guillotine cutter that moves up and down. May be.
[0068]
By the way, in such a tablet dividing machine, fine powder is scattered in the dividing machine. For this reason, there is a need for a tablet divider that is easy to clean. In other words, a structure that can be easily cleaned may be used.
[0069]
Still another embodiment of the present invention will be described with reference to FIGS. In the figure, the same components as those in FIGS. As can be seen from FIG. 20, in this tablet dividing machine, as many movable parts as possible are arranged on the other side of the side wall 2 ′, the mechanism on this side is simplified, and cleaning is facilitated.
[0070]
FIG. 18 is a perspective view of the tablet dividing machine 1 ′. 54 ′ is a receiving tray for receiving the tablet divided into two. This receptacle 54 'is shown in FIGS. 19 (a) and 19 (b). Reference numeral 102 denotes a removal cover for the tablet dividing machine.
[0071]
In FIG. 20, 19 'is a baffle plate by a spring (not shown). Reference numeral 16 'denotes a rotating arm. 16A ′ is a push plate. Reference numeral 16B ′ denotes a baffle plate regulating lever.
[0072]
Reference numerals 42 'and 41' denote clamping plates.
[0073]
Reference numeral 23 'denotes a holding roller. The holding roller 23 ′ has an uneven surface on the rubber roller surface. And it is comprised so that the unevenness | corrugation on either side may be made into object.
[0074]
The operation of this embodiment will be described.
[0075]
First, when a split operation is performed, the rotary arm 16 ′ and the clamping plates 41 ′ and 42 ′ are set to the initial positions.
[0076]
First, one tablet is discharged from the tablet feeder. And the tablet M falls to the channel | path 14 like FIG.
[0077]
The rotary arm motor 17 ′ is driven and the push plate 16 A ′ pushes the tablet M.
[0078]
As shown in FIG. 21, the tablet M hits the baffle plate 19 ′. And if the tablet M is a rectangular parallelepiped, a long side will come to follow the surface of 16 A 'of pressing plates. In FIG. 21, since the tablet M is cylindrical, posture control is not performed on this tablet.
[0079]
Further, the push plate 16A ′ rotates, and the tablet M slides down the slope plate 18 as shown in FIG. At this time, the return of the baffle plate 19 ′ to the original position is restricted by the restriction lever 16B ′ until the push plate 16A returns to the original position.
[0080]
The dropped tablet comes into contact with the shutter 22 'and stops.
[0081]
Then, the shutter 22 is opened, and the tablet M is dropped to the contact position of the roller 23 '. Since the drop distance at this time is short, the tablet M does not bite into the roller 23 '.
[0082]
Next, the clamping plates 41 ′ and 42 ′ move in the center direction, and the center of the tablet M and the position of the rotary blade 36 are aligned.
[0083]
In the third embodiment, the roller 23 'is driven next. The tablet M remains sandwiched between the sandwiching plates 41 ′ and 42 ′, but if the sandwiching force by the sandwiching plates 41 ′ and 42 ′ is weak, the tablet is transported by the roller 23 ′ without any problem. However, if the pinching force is strong, the roller 23 'does not carry.
[0084]
That is, if the clamping force is weak, the tablet is conveyed by the roller 23 'without any problem. However, if a motor (not shown) having a large torque is used for driving the sandwiching plates 41 ′ and 42 ′, the sandwiching force is increased and the conveyance by the roller 23 ′ is not performed.
[0085]
Therefore, before the roller 23 'is driven, the clamping plates 41' and 42 'are returned to the initial positions.
[0086]
However, if this is done, the tablet M may be tilted at the start of holding the tablet by the roller 23 ′ and the holding spring 21.
[0087]
Therefore, in this embodiment, before the roller 23 ′ is driven, the clamping plates 41 ′ and 42 ′ are controlled so as to be slightly expanded.
[0088]
After this expansion, the roller 23 'is driven. When the tablet M starts to hold the tablet by the roller 23 ′ and the holding spring 21, the sandwiching plates 41 ′ and 42 ′ serve as a guide and prevent the tablet M from tilting.
[0089]
As a result, the tablet M is conveyed by the roller 23 ′ and the holding spring 21 without tilting the tablet M.
[0090]
Thereafter, the sandwiching plates 41 and 42 are further expanded and returned to the initial position.
[0091]
Then, the tablet M is conveyed by the roller 23 ′ and cut by the rotary blade 36.
[0092]
Then, the divided tablet falls into the tray 54 ′.
[0093]
By the way, the problem regarding the fall of the tablet from the tablet case 100 is demonstrated.
[0094]
As schematically shown in FIG. 24A, the tablet M dropped from the tablet case 100 lies in the passage. However, when the tablet has a cylindrical shape as shown in FIG. 24B, the dropped tablet M may stand up. The standing tablet M is a heel lying on the inclined plate 18, but may move to the position of the shutter 23 'while standing. Therefore, in the present application, as shown in FIG. 24C, the posture changing plate 101 is attached to the dropping path of the tablet M so that the tablet M is laid down.
[0095]
【The invention's effect】
As described above, according to the present invention, it is possible to realize a simple configuration when aligning the postures of tablets.
[0096]
As described above, according to the present invention, even if the tablet has a shape other than a circle, the tablet can be accurately divided.
