In such a medicine packing device 10, a lozenge dispensing apparatus 100 according to an embodiment of the present invention is provided between the lozenge storage units 11 and the final medicine bucket 12 and can supply a special lozenge into the final medicine bucket 12. The special tablet is a tablet different in shape from a general tablet, or a tablet of half or a fraction of a tablet, or the like.

Fig. 2 is an oblique view of a tablet dispenser according to an embodiment of the present invention, fig. 3 is an oblique view of fig. 2 in a state where a tablet tray is drawn out, fig. 4 is a partially exploded oblique view of fig. 2, fig. 5 is an exploded oblique view of a conveyor and a storage container of fig. 4, and fig. 6 is a sectional view of fig. 2.

Referring to fig. 2 to 6, the lozenge dispensing apparatus 100 includes a fixing frame 110, a dispensing tray 120, a gate 130, a conveyor 140, a plurality of storage containers 150, a position detection unit 160, and a control section 170.

The fixing frame 110 is fixed to the inside of the medicine packing device 10. The dispensing tray 120 is supported by the fixed frame 110 in a state of being inserted into the fixed frame 110 to be horizontally linearly movable and extractable outside the medicine packing device 10. For example, the dispensing tray 120 is supported by the fixed frame 110 to be drawn out toward the front of the medicine packing device 10. Here the dispensing tray 120 may be fixed to a movable frame 126. The moving frame 126 horizontally linearly moves the fixed frame 110 by means of a linear guide.

The linear guide may include a pair of fixed rail units 111 formed on the fixed frame 110 and a moving rail unit 127 formed on the moving frame 126. The fixed rail unit 111 and the moving rail unit 127 guide the moving frame 126 to linearly move in a mutually coupled state. In order to smoothly move the moving frame 126, a plurality of guide rollers which are rotatably contacted with lower portions of the respective moving rail units 127 are provided on the fixed frame 110.

The dispensing tray 120 is formed with a plurality of tablet dispensing holes 121 that receive tablets that are dispensed by a pharmacist in a single dose. The tablet dispensing holes 121 are arranged at least in a horizontal row, and the tablet dispensing holes 121 are arranged at regular intervals in the row direction. The lozenge dispensing apertures 121 may be provided in more than two rows.

The tablet dispensing tray 120 reciprocates a tablet storage position outside the medicine packing device 10 and a tablet discharge position inside the medicine packing device 10 by the moving frame 126. The tablet storage position here refers to a position where the pharmacist draws the tablet dispensing tray 120 out of the medicine packaging apparatus 10 in order to dispense tablets to the tablet dispensing holes 121. The tablet dispensing position is a position at which the tablet dispensing tray 120 is inserted into the medicine packaging apparatus 10 in order to dispense tablets received in the tablet dispensing holes 121 to the storage containers 150 on the upper layer of the conveyor belt.

Although not shown, each tablet dispensing hole 121 may be provided with a storage detection unit that detects whether or not a tablet is stored, or may be provided with a display unit that displays whether or not a tablet is stored. The storage detection unit may be constituted by an optical sensor or the like, and the display unit may be constituted by an LED or the like. The information detected by the storage detection part may be provided to the control part 170.

The control unit 170 may display the stored state if it determines that the tablet is stored in the tablet dispensing hole 121 based on the information detected by the storage detection unit. For example, the control unit 170 lights the LED or lights the LED for setting the display accommodation color. Furthermore, the control unit 170 may turn off the LED when the storage is completed after the LED is turned on in order to distinguish and instruct the storage.

A shutter 130 is provided below the dispensing disc 120 to open and close the tablet dispensing hole 121. The shutter 130 may simultaneously close each tablet dispensing hole 121. Therefore, when the lower portions of the tablet dispensing holes 121 are simultaneously opened, the tablets received in the tablet dispensing holes 121 are supplied to the storage containers 150. The shutter 130 is controlled by the control unit 170.

The conveyor 140 includes a belt 141 that is provided to face the tablet dispensing holes 121 in the upper row direction in a state where the tablet dispensing pan 120 is inserted into the fixed frame 110 and runs on a crawler. The conveyor belt 141 is rotated by means of a pair of pulleys 142. The conveyor 141 may be a V-shaped conveyor to prevent the conveyor from slipping off the pulleys 142. Each pulley 142 is rotatably mounted on the fixed frame 110. One of the pulleys 142 may be rotated by the rotation driving part 143.

The rotation driving part 143 may include a rotation motor, a driving gear, and a driven gear. The driving shaft of the rotating motor is connected with the driving gear. The driven gear is engaged with the driving gear and fixed to the rotation center of the pulley 142. Accordingly, the pulley 142 is rotated by the rotational driving force of the rotating motor, and the belt 141 is operated as a crawler belt.

The storage containers 150 are fixedly arranged on the outer side of the conveyor 141 at the same pitch as the pastille dispensing holes 12 in a row direction and are movable to supply the pastilles discharged from the pastille dispensing holes 121. The storage container 150 has an inner space and an opening at an upper end, and a lower end is fixed to the conveyor belt 141.

The position detection unit 160 detects the position of each storage container 150. The position detecting unit 160 includes a plurality of magnet units 161 and hall sensors 162, the magnet units 161 being disposed on the respective storage containers 150, and the hall sensors 162 being fixed on the transfer path of the respective storage containers 150 and being capable of detecting any one of the magnet units 161. Each magnet unit 161 may generate a magnetic field. The magnet unit 161 is constituted by a pair of permanent magnets 161 a. A pair of permanent magnets 161a are disposed at an interval between which the hall sensor 162 can be mounted and may be mounted on the storage container 150.

The hall sensor 162 detects a magnetic field by generating a hall effect in a direction perpendicular to a current and the magnetic field by a voltage when the current causes the current conductor to generate the magnetic field. The hall sensor 162 detects the position of the storage container 150 according to the detection of any one of the magnet units 161. The hall sensors 162 may be sequentially and correspondingly fixed to the fixed frame 110 when the respective storage containers 150 are transferred by the conveyor 140, and the respective magnet units 161 of the storage containers 150 may be fixed to the fixed frame 110. Meanwhile, in a state where each storage container 150 on the upper layer of the conveyor belt 141 is accurately moved to a position where a tablet is discharged from the tablet receiving and dispensing hole 121, the hall sensor 162 is fixed at a position where any one of the storage containers 150 can be detected. The hall sensor 162 may be provided in two or more numbers.

The control unit 170 controls the conveyor 140 to set each storage container 150 at a set position based on the information detected by the position detection unit 160. As shown in fig. 6, the controller 170 controls the conveyor 140 based on the information detected by the position detector 160, so that each storage container 150 on the upper layer of the conveyor 141 can accurately correspond to each tablet dispensing hole 121 at the tablet dispensing position, and each storage container 150 is in a waiting state. At this time, the control unit 170 controls the conveyor 140 based on the information detected by the hall sensor 162 so that any one of the storage containers 150 is accurately positioned at the hall sensor 162.

In this state, when the tablet dispensing tray 120 receives tablets in the tablet receiving position into the tablet dispensing holes 121 and then inserts the tablets into the tablet dispensing position, the control unit 170 controls the shutter 130 to open the tablet dispensing holes 121. Thereafter, as shown in fig. 7, the tablets are discharged from the tablet dispensing holes 121 and supplied into the storage containers 150 on the upper layer of the conveyor belt 141. Subsequently, the controller 170 controls the conveyor 140 to rotate the storage containers 150 on the upper layer of the conveyor 141 one by one in the direction of the front end of the conveyor 140, and the tablets in the storage containers 150 are supplied into the intermediate hopper 101. At this time, the control unit 170 controls the conveyor 140 so that the hall sensors 162 correspond to the storage containers 150 one by one based on the information detected by the hall sensors 162. The pastilles supplied to the intermediate hopper 101 are transferred to the final hopper 12.

Through this process, when all the tablets are discharged from the storage containers 150, the respective storage containers 150 on the conveyor belt 141 are put into a waiting state accurately corresponding to the respective tablet dispensing holes 121. Therefore, when the tablet dispenser 100 is used for a long time, the slide phenomenon occurs between the conveyor belt 141 and the pulley 142, and the storage containers 150 on the conveyor belt 141 are in a state corresponding to the tablet dispensing holes 121, respectively, so that tablets can be accurately received.

On the other hand, the tablet dispensing holes 121 may be arranged in 3 rows. Generally, the maximum number of troches taken per day is three times in the morning, in the middle of the day, and in the evening. Tablets taken in the morning are received in tablet dispensing holes 121 in the first row, tablets taken in the noon are received in tablet dispensing holes 121 in the second row, and tablets taken in the evening are received in tablet dispensing holes 121 in the third row.

The conveyor 140 has 3 and each conveyor belt 141 corresponds to each row of tablet dispensing holes 121. Each storage container 150 is fixed to each conveyor belt 141 of the conveyor 140. Meanwhile, the position detecting unit 160 described above is mounted on each conveyor 140. The 3 conveyors 140 are independently controlled by the control section 170. Therefore, tablets dispensed through the tablet dispensing holes 121 are sequentially supplied to the intermediate hoppers 101 one by one after being supplied to the storage containers 150. In this case, various formulation methods are also applicable as follows.

For example, in the general case of tablets prescribed for morning, noon and evening administration, the pharmacist dispenses a quantity of tablets taken in the morning during tablet dispensing aperture 121 in the first row, a quantity of tablets taken at noon during tablet dispensing aperture 121 in the second row, and a quantity of tablets taken in the evening during tablet dispensing aperture 121 in the third row. The pharmacist then operates the lozenge dispenser 100 as follows. First, tablets stored in the tablet dispensing holes 121 are discharged into the storage containers 150 of the respective rows via the gate 130. Thereafter, the conveyors 140 are driven independently of each other, and tablets are fed to the intermediate hopper 101 by rotating in the front end direction of the conveyors 140 in the order of the first row, the second row, and the third row of the storage containers 150 in the first row. The storage containers 150 in the next row are also sequentially moved in the same manner and tablets are supplied to the intermediate hopper 101.

If a formula is to take 2 lozenges in the morning and evening, the pharmacist can dispense a row of lozenges through dispensing aperture 121 to dispense lozenges taken in the morning and another row of lozenges through dispensing aperture 121 to dispense lozenges taken in the evening. The pharmacist then operates the tablet dispenser 100 to individually drive the two conveyors 140 corresponding to the two rows of storage containers 150 to sequentially supply tablets to the middle hopper 101.

If the same type of tablet is prescribed for morning, evening or once a day, the pharmacist may dispense tablets only into each tablet dispensing aperture 121 of at least one row. Thereafter, the pharmacist operates the tablet dispenser 100 to drive only 1 conveyor 140 corresponding to one row of each storage container 150 to supply tablets to the intermediate hopper 101.

In addition to the above examples, tablets may be stored in the tablet dispensing tray 120 in other manners. Tablets in the morning, noon, evening, before sleep, etc. are stored in a row in the tablet dispensing holes 121. In this case, the tablets can be stored more conveniently by using color LEDs separately stored, a storage detection section for detecting storage, and a control section 170 for controlling the color LEDs based on information provided by the storage detection section.

Meanwhile, according to the lozenge dispensing apparatus 100, although 1 pack of lozenges may be packed per lozenge dispensing opening 121, more than two lozenge dispensing openings 121 may be combined as prescribed to prepare a preparation in order to pack an amount of lozenges exceeding the size of the lozenge dispensing opening 121 into 1 pack, depending on the choice of options.

Each tablet dispensing aperture 121 may be formed in two or four rows. When the tablet dispensing holes 121 are formed in four rows, the desired tablets can be combined to prepare a combined preparation after the same tablet is stored in each row. For example, the tablet dispensing holes 121 of one row receive the tablets a, the tablet dispensing holes 121 of two rows receive the tablets B, the tablet dispensing holes 121 of 3 rows receive the tablets C, and the tablet dispensing holes 121 of four rows receive the tablets D. At this time, the control part 170 drives each conveyor 140 individually, and may be a combination of a troche and B troche in the morning, a combination of a troche and B troche, C troche in the noon, and a combination of a troche and D troche in the evening.

In other examples, 1 or two tablets may be received in each tablet dispensing hole 121 of the tablet dispenser 100. In this case, the occurrence of wrong dispensing caused by complicated prescription of pharmacist can be reduced. Also, where there are no non-standard lozenge feeders in the pharmaceutical packaging 10, the lozenge dispenser 100 may be used as a non-standard lozenge feeder.

In another example, as shown in fig. 8, the position detecting unit 260 includes sensor substrates 261 mounted on the storage containers 150 and photosensors 262 that detect any one of the sensor substrates 261 fixed on the transfer paths of the storage containers 150. The photosensor 262 includes a light emitting portion 262a and a light receiving portion 262 b. When the photosensor 262 is located in the linear movement section of the conveyor belt 141, the light emitting section 262a and the light receiving section 262b are provided at an interval from each other. Each sensor substrate 261 is positioned between the light emitting portion 262a and the light receiving portion 262b while sequentially passing through the storage containers 150.

If the light receiving part 262b does not receive the light emitted from the light emitting part 262a, it is detected that the sensor substrate 261 has entered between the light emitting part 262a and the light receiving part 262 b. If the light receiving portion 262b receives the light emitted from the light emitting portion 262a, it is detected that the sensor substrate 261 does not enter between the light emitting portion 262a and the light receiving portion 262 b. Therefore, the position of the storage container 150 is detected as the optical sensor 262 detects any one of the sensor substrates 261.

On the other hand, referring again to fig. 5, each storage container 150 may be mounted on the conveyor belt 141 or may be separated from the conveyor belt 141. Therefore, the administrator can separate each storage container 150 from the conveyor belt 141, thereby facilitating cleaning of the inside of each storage container 150 and facilitating maintenance and management of each storage container 150. For example, the lower end of each storage container 150 may be inserted onto the conveyor belt 141. The transfer belt 141 is formed with coupling holes 141a corresponding to the respective storage containers 150. The lower end of each storage container 150 is formed with a coupling protrusion 151 that can be inserted into the coupling hole 141 a. The lower end of the coupling protrusion 151 includes hooks 151a extended toward both sides, respectively.

After the central portion of the coupling protrusion 151 passes through the coupling hole 141a, the hook 151a is caught by the inner surface of the conveyor belt 141, and the storage container 150 is fixed to the conveyor belt 141. At this time, the center of the pulley 142 may be formed with a groove 142a in the center circumference. When each storage container 150 is rotated via the pulley 142, the hooks 151a of each coupling protrusion 151 may pass through the grooves 142a of the pulley 142, and thus the storage containers 150 do not collide with the pulley 142. Each storage container 150 may be formed of an elastic material such as silicon, rubber, etc. to be easily inserted into the conveyor belt 141 or separated from the conveyor belt 141. The portion of each storage container 150 coupled to the conveyor belt 141 may be formed of an elastic material.

In another example, as shown in fig. 9 to 10, the storage container 250 has two separated first and second divided container parts 251 and 252 in a vertical transfer direction and may be inserted into the conveyor 141, respectively. Coupling protrusions 251a and 252a are formed on lower ends of the first and second divided container parts 251 and 252 so as to be capable of being caught in the coupling holes 141a of the conveyor belt 141.

Since the conveyor 141 is bent in the curved section of the direction change, stress applied to the coupling portion of the storage container 250 and the conveyor 141 may be increased when the storage container 250 passes through the curved section of the conveyor 141. However, when the storage container 250 is separated into the first divided container part 251 and the second divided container part 252 and then the conveyor belt 141 is connected, when the storage container 250 passes through the curved section of the conveyor belt 141, the first divided container part 251 and the second divided container part 252 spread and stress on the portion where the conveyor belt 141 is connected is reduced. Accordingly, the force applied to the conveyor belt 141 is reduced, thereby reducing the driving load of the conveyor 140. When the pair of permanent magnets 161a are attached to the storage container 250, one permanent magnet 161a may be attached to each of the first divided container part 251 and the second divided container part 252.

Each storage container 250 may be formed of an elastic material, but the storage container 250 may be formed of an elastic material as a whole. As shown in fig. 11, the first divided container part 251 of any one storage container 250 and the second divided container part 252 of the adjacent storage container 250 may be coupled together at a lower portion. Meanwhile, the second divided container part 252 of any one storage container 250 may be connected with the first divided container part 251 of the adjacent other storage container 250 at a lower portion. That is, the coupling protrusion 251a of the first divided container part 251 of any one storage container 250 may be coupled to the coupling protrusion 252a of the second divided container part 252 of the adjacent one of the storage containers 250. Meanwhile, the coupling protrusion 252a of the second divided container part 252 of any one storage container 250 may be coupled with the coupling protrusion 251a of the first divided container part 251 of the adjacent other storage container 250.

Accordingly, each storage container 250 may be better supported by the conveyor belt 141. Further, since the portion of any one of the storage containers 250 adjacent to the first divided container part 251 and the second divided container part 252, which is connected to the first divided container part 251, may be formed of an elastic material, the storage containers 250 may be more easily separated from each other when the storage containers 250 pass through the curved section of the conveyor belt 141. Thereby reducing the force applied to the conveyor belt 141.

In other embodiments, as shown in FIG. 12, the storage container 350 may include a base partition 351 and a pair of elongated partitions 352. The base partition 351 is disposed perpendicular to the widthwise direction of the conveyor belt 141 and the lower end may be fixed to the conveyor belt 141. Each of the extension partitions 352 is separated from the outer surface of the conveyor 141 and extends from both edges of the basic partition 351 toward the running direction of the conveyor 141. Each of the extension partitions 352 of any one of the storage containers 350 is in contact with the base partition 351 of the adjacent storage container 350 in a linear section of the conveyor belt 141. Accordingly, the storage containers 350 are closed around the straight section of the conveyor 141 and can store tablets.

Since the storage containers 350 are fixed to the conveyor 141 only at the lower end portions of the basic partitions 351 in the width direction of the conveyor 141, stress applied to the coupling portions with the conveyor 141 when the storage containers pass through the curved sections of the conveyor 141 can be minimized. Thereby reducing the force applied to the conveyor belt 141 and thus the driving load of the conveyor 140.

In other embodiments, as shown in FIG. 13, each storage vessel contains 1 partition 451. Each partition 451 is perpendicular to the widthwise direction of the conveyor belt 141 and the lower end thereof may be fixed to the conveyor belt 141. Each partition 451 forms each storage space 452 of the storage container with its adjacent partition 451. Meanwhile, since the guide members 456 are formed to correspond to the open portions on both sides of the storage space 452, the storage space 452 is closed by the guide members 456 having both open sides. The guide members 456 prevent tablets in the storage spaces 452 from flowing out through the open portions on both sides of the storage spaces 452 when tablets are supplied to the storage spaces 452 or when tablets are transferred to the storage spaces 452. Each guide part 465 may be fixedly mounted on the fixed frame 110.

Referring to fig. 14 to 16, the shutter 130 includes a shutter unit 131 and a shutter unit driving part 132. The gate unit 131 is formed with a plurality of output holes 131 a. The shutter unit 131 is formed of a metal plate whose entire portion except for the output holes 131a is closed. The discharge holes 131a are arranged in an array corresponding to the tablet dispensing holes 121. When the shutter unit 131 is transferred to the front of the medicine packaging apparatus 10 in a state where the tablet dispensing holes 121 are closed, the tablet dispensing holes 121 corresponding to the tablet dispensing holes 121 are opened by the output holes 131 a.

The gate unit 131 may perform a horizontal linear movement under the dispensing tray 120. For example, the dispensing tray 120 includes guide units 122 formed on the lower surfaces of both side edges with respect to the linear movement direction of the shutter unit 131. The guide units 122 and the dispensing tray 120 may be inserted between both edges of the gate unit 131 and guide the gate unit 131 to linearly move.

The shutter unit driving section 132 drives the shutter unit 131 so that each discharge hole 131a corresponds to or separates from each tablet dispensing hole 121. The shutter unit driving portion 132 includes a shutter unit elastic member 133, a movable member 134, a rotary motor 135, a rack 136, and a pinion gear 137.

The gate unit 131 is positioned to close each tablet dispensing hole 121 by applying an elastic force to the gate unit 131 by the elastic member 133. The shutter unit elastic member 133 is formed of a coil spring, and both ends are fixed to the movable frame 126 and the shutter unit 131, respectively. The shutter unit 131 is supported by the positioning pins 123 in a state of moving to close each tablet dispensing hole 121.

The movable piece 134 is fixed to the gate unit 131. The rotating motor 135 is mounted on the fixed frame 110. The main body of the rotating motor 135 is fixed to the fixed frame 110, and the rotating shaft of the rotating motor 135 may be fixed to the pinion gear 137. The rotary motor 135 can drive the rotary shaft in the forward and reverse directions. A front portion of the rack 136 is engaged with the pinion gear 137 in a state corresponding to the movable element 134.

For example, rotating motor 135 rotates pinion gear 137 causing rack gear 136 to push moveable member 134. Accordingly, the shutter unit 131 is moved to a position for opening each tablet dispensing hole 121 by the urging of the movable piece 134. Thereafter, the rotating motor 135 rotates the pinion gear 137 in the opposite direction to release the state in which the rack 136 pushes the movable element 134. Thus, shutter unit 131 is movable by shutter unit elastic member 133 to a position closing each lozenge dispensing opening 121.

The gate unit driving portion 132 may include a mover sensor (not shown) that detects a position of the mover 134. Information detected by the movable element sensor may be transmitted to the control portion 170, and the control portion 170 controls the opening and closing operation of the gate unit 131 by the rotating electric machine 135 based on the position information of the movable element 134. The moving member sensor may be a general optical proximity sensor or the like. On the other hand, the shutter unit driving section 132 may be configured in another manner having the above-described function.

As shown in fig. 17 and 18, the tablet dispenser 100 includes a linear moving unit 180, and the linear moving unit 180 drives the moving frame 120 to linearly move. Accordingly, the dispensing disc 130 may be automatically withdrawn from the medicament packaging device 10 or automatically inserted into the medicament packaging device 10. The linear moving unit 180 includes a rotary motor 181 and a linear motion converting unit 182. The main body of the rotating electric machine 181 is fixed to the fixed frame 110. The rotary motor 181 can rotate the rotary shaft in the forward and reverse directions.

The linear motion converting unit 182 converts the rotational motion of the rotary motor 181 into a linear motion and transmits the linear motion to the moving frame 126. For example, the linear motion converting unit 182 includes a pinion gear 182a and a rack gear 182 b. The pinion gear 182a is rotated by the rotational force of the rotating motor. The rack gear 182b is engaged with the pinion gear 182 a. The rack gear 182b is disposed parallel to the linear moving direction of the moving frame 126 and fixed to the fixed frame 110.

The linear moving unit 180 includes a limit detecting unit 183a that can limit the moving range of the moving frame 126. The limit detection unit 183a detects the 1 st sensor substrate 183b of the fixed frame 110 when the movable frame 126 is at the tablet output position where the dispensing tray 120 is inserted into the medicine packing apparatus 10. Meanwhile, the limit detection unit 183a may detect the 2 nd sensor substrate 183c of the fixed frame 110 when the moving frame 126 is in a position where the dispensing tray 120 is drawn out to the tablet storage position outside the medicine packing device 10.

The information detected by the limit detection unit 183a may be provided to the control part 170, and the control part 170 may accurately control the moving frame 126, that is, the tablet output position and the tablet receiving position of the dispensing tray 120, by means of the rotating motor 181. The limit detection unit 183a may be a hall sensor, and the 1 st and 2 nd sensor substrates 183b and 183c may be permanent magnets. The limit detection unit 183a is not limited to the hall sensor, and other elements such as an optical proximity sensor may be used.

Fig. 19 is a block diagram showing an example of a tablet transfer unit that transfers tablets supplied from an intermediate tablet bucket to a final tablet bucket.

Referring to fig. 19, the tablet transfer unit 190 includes a housing 191, a screw 192, and a rotation driving part 193. The outer cover 191 is a hollow round through structure. The cover 191 is provided in an inclined form and rotated in the circumferential direction by the rotation driving unit 193. The upper part of the cover 191 forms a supply port for receiving tablets from the intermediate hopper 101, and the lower part forms an output port for outputting tablets to the final hopper 12. During the rotation of the cover 191, the supply port of the cover 191 corresponds to the output port of the intermediate hopper 101, and the output port of the cover 191 corresponds to the through hole formed in the side surface of the final hopper 12.

The spiral 192 is formed inside the outer cover 191. The screw 192 rotates with the housing 191 and transports the pastilles in the direction of the screw. The spiral 192 forms a spiral-shaped transfer blade 192b along the circumference of the main shaft 192 a. Therefore, when the pastilles are supplied into the space formed by the cover 191 and the transfer blade 192b through the supply port of the cover 191, the pastilles are conveyed downward in the spiral direction by the transfer blade 192b after the cover 191 rotates, and finally are output through the output port of the cover 191. The rotation driving part 193 rotates the housing 191. The rotation driving unit 193 may employ a rotation driver such as a rotary motor.

In other embodiments, the screw 192 may be rotated in a state of being separated from the housing 191, and the tablet may be transferred in a screw direction in the same manner. Also, the tablet transfer unit may include a conveyor. The conveyor drives the conveyor belt to move pastilles received from the intermediate hopper 101 over the conveyor belt towards the final hopper 12.

The intermediate hopper 101 may have a vibrating means 102 thereon. When the horizontal inclination angle of the intermediate hopper 101 is small, the tablet size is small, and the tablet contains much powder, the speed of tablet transfer to the tablet transfer unit 190 may be slowed down. Therefore, the vibration tool 102 vibrates the middle hopper 101, and the tablet can be conveyed to the tablet transfer unit 190 at a higher speed. The vibration tool 102 may employ a vibration motor or the like.

A discrimination sensor 103 may be provided in the final hopper 12 to identify the stored single dose of tablets and to identify the presence of a formulation error. The agent erroneous discrimination sensor 103 may be a camera or the like capable of photographing the direction of the outlet of the final medicine bucket 12.

On the other hand, the dispensing tray 120 may be formed by stacking a plurality of trays one on top of another.
