FIG. 4 shows one traveling track 301 in the tablet pick-up device 300 of the dispensing device 1 from the side. In the figure, 303 is a circular trajectory, 304 is a shelf that moves up and down in a horizontal state, 305 is a suction device that picks up individual packaging t, 306 is a cylinder that raises and lowers the

suction device

305, and 307 is provided on the outer periphery of the suction device 305. The sensor 308 detects that the suction device 305 has sucked the individual package t, and 308 is a moving device that moves the suction device 305 to the position of the chute 302 provided on the front side (top plate 203 side) of the tablet pickup device 300. The circular orbit 303 is rotated clockwise by a motor (not shown). The moving device 308 extends to a position immediately above the top position of the circular track 303 and can move the suction device 305 to and from the chute 302.

Reference numerals

322 and 323 denote imaging devices that acquire an image of the tablet sheet m adsorbed by the adsorption device 305. Below the top position of the circulating track 103, there are provided an ejection device 320 for ejecting air and a cylinder 321 for raising / lowering the ejection device 320.

FIG. 5 shows the suction device 305 and the shelf 304 in more detail. In FIG. 5A, the suction device 305 includes a suction nozzle 310, a hood 311, and a rim 312. FIG. 5B is a cross-sectional view of the hood 311 and the rim 309. The inner surface of the hood 311 is a concave curved surface with the position of the suction nozzle 310 at the top. In the illustrated embodiment, the suction nozzle 310 is at the top and descends while spreading in all directions. For example, the bowl is turned upside down. The suction port 313 of the suction nozzle 310 opens at the top of the hood 311. The contact 314 of the sensor 307 is provided in the vicinity of the suction port 313 and outputs a detection signal when the individual package t is caught by the suction port 313. The hood 311 is made of resin or metal having a smooth inner surface, and a thick rim 309 made of elastic resin is provided at the peripheral end. The size of the rim 309 corresponds to the size of the upper opening of the case 3. When the suction device 305 is lowered by the cylinder 306 and inserted into the case 3, the inside of the case 3 is individually separated by the hood 311. A closed space is formed so as not to allow the package to pass through.

FIG. 5C shows Case 3. Although the bottom surface of the case 3 is flat, a large number of through holes 35 are provided on the entire surface. This through-hole 35 is a hole smaller than the individual package t, and allows the air flow ejected from the ejection device 320 disposed on the lower side to pass when positioned at the apex of the circulation track 303. Further, an airflow reversing plate 30 that reverses the airflow introduced into the case 3 through the through hole 35 is provided inside and at the center of the case 3. The airflow reversing plate 30 includes a guide plate 34 that guides the airflow in the vertical direction and a curved plate 33 that distributes the airflow left and right and directs the direction of the airflow downward. The position of the end 36 of the curved plate 33 does not reach the opposing wall 37, and this interval is an interval through which the individual packaging t can pass freely.

FIG. 6 shows a state in which the

adsorption devices

105 and 305 adsorb the tablet sheet m and the individual package t. In FIG. 6A, the adsorption device 105 adsorbs a tablet sheet m having a certain length. The sensor 107 outputs a detection signal when the suction device 105 sucks the tablet sheet m.

FIG. 6B shows a state in which the adsorption device 305 is inserted inside the case 3 and an air flow is sent by the ejection device 320. The rim 312 of the hood 311 is in contact with the wall 37 of the case 3 so that the individual package t is not missed. The shelf 304 has a large opening at the bottom so that the through hole 35 can be directly positioned with respect to the ejection device 320.

Air ejection from the ejection device 320 and suction by the suction nozzle 310 are started. The air flow sent from the ejection device 320 rises along the guide plate 34 while lowering the curved plate 33 while winding up the individual packaging inside the case 3. Due to the airflow reversal plate 30, it is not possible to lift the suction nozzle 310 directly above the case 3 in the vicinity of the center of the case 3. The peripheral portion where the airflow is lowered by the curved plate 33 also collides with the ascending airflow generated by the ejection device 320, and it is difficult to further raise the individual package t at this location. Eventually, the individual package t rises along the inner wall of the hood 311 through the wall 37 at the location of the wall 37 of the case 3. The individual packaging t is capable of adsorbing a flat surface portion that is convex as a result of molding a plate-like plastic with vacuum foam or the like and a portion of the mount that is placed flat on the back side across the tablet. However, if a large number of individual sheets t rush to the suction nozzle 310 in a side surface or in an oblique state, suction by suction is difficult. However, in this embodiment, a large number of individual packages t are not flooded into the suction port 313 in this way, and the suction port 313 reaches the suction port 313 along the wall of the hood 311. It can be adsorbed to the suction port 313.

For this reason, it is only necessary to put the PTP tablet sheet into the case 3 in a disassembled state, and the individual packaging t can be easily replenished.

In addition, since the air flow is introduced through the through hole 35 at the bottom of the case 3, the bottom surface of the case 3 may be a flat surface and unnecessary structures are unnecessary. A shelf 304 can be installed. FIG. 7 is a control flow of the control unit 10 of the dispensing device 1, and the operation of the dispensing device 1 will be described according to the flow. First, the tablet sheet m is filled in the case 2 and the individual packaging t in the disassembled state is replenished in the case 3, and the cases 2 and 3 are set in the

shelves

104 and 304. Information on the relationship between the

tags

22 and 32 of the cases 2 and 3 and the

shelves

104 and 304 is stored in the control unit 10 as to whether or not the tablets are replenished.

The dispensing device 1 acquires tablet information from the prescription (step S1). This information acquisition may be input from paper information of a prescription, or electronic data of an electronic prescription may be used.

From the type and number of tablets specified by the prescription data, the number and fraction of tablet sheets are determined for the corresponding tablet based on the number of tablets registered in advance (step S2). For example, assuming that XX tablets are specified as 3 tablets per day and 12 tablets per day, if the tablet sheet of XX tablets contains, for example, 10 tablets, one tablet sheet and a fraction Is 2 tablets.

The sheet pickup apparatus 100 is instructed to pick up the tablet sheet m. The sheet pickup device 100 moves the traveling track 103 so that the shelf 104 of the case 2 accommodating the target tablet sheet m is positioned at the top of the traveling track 103 (step S31).

The tablet sheet m is acquired (S32). At this time, if the case 2 is divided into a plurality of sections in the case 2 imaged by the imaging device 122, a pickup operation is performed on the section where the tablet sheet m exists in cooperation with the moving device 108. When the suction device 105 is moved to a position immediately above the chute 102 by the moving device 108, the tablet sheet m is dropped onto the chute 102. The imaging device 123 acquires an image of the tablet sheet m that has appeared on the chute 102 by the adsorption device 105, an image of the tablet sheet that falls on the chute 102, an error in acquiring the tablet sheet m by the control unit 10, or a drop error. This event is confirmed (S33).

When a plurality of tablet sheets m are requested, the suction device 105 returns to the top of the circulation track 103, picks up the tablet sheet m, and repeats the operation of dropping it onto the chute 102 as necessary. In addition, the control unit 10 inspects the contents of the case 2 imaged by the imaging device 122 located at the top of the circular trajectory 103. For example, when the tablet sheet remains only in one section, the operator Asks to replenish the tablets.

Next, the tablet pickup device 300 is instructed to pick up the tablets in the individual package t. The tablet pick-up device 300 moves the traveling track 303 so that the shelf 304 of the case 3 accommodating the target individual package t is positioned at the top of the traveling track 303 (step S41).

Individual packaging t is acquired (S42). When the suction device 305 is moved to a position immediately above the chute 302 by the moving device 308, the individual packaging t is dropped onto the chute 302. The imaging device 323 acquires an image of the individual package t falling on the chute 302, and confirms an event such as an error in acquisition of the individual package t by the control unit 10 or a fall error (S43).

When a plurality of individual packages t are required, the suction device 305 returns to the top of the circulation track 303, picks up the individual packages t, and repeats the operation of dropping them on the chute 302 as necessary. In addition, the control unit 10 inspects the contents of the case 3 imaged by the imaging device 322 located at the top of the circular trajectory 303, and when the amount of the individual packaging t is small, the operator is replenished with tablets. To display on the display unit 11.

The image data of the picked up tablet sheet m and the individual packaging t is stored as log data by the

imaging devices

130 and 330 provided in the receiving portions 131 and 331 (S5).

In the above embodiment, if the front side surface on the top plate 203 side and the

chutes

102 and 302 of the sheet pickup device 100 and the tablet pickup device 300 are formed of a transparent member such as acrylic resin, clogging of the tablets can be visually confirmed. . In the above-described embodiment, an example of the dispensing device 1 that collects and picks up the number of tablets specified by the prescription is shown, but once for each of the three times of morning, noon, and evening specified by the prescription. You may use for the packaging apparatus which divides | segments for every dose. In this case, the medicine is not in the form of an individual package t, and the tablet is stored in the case 2 of the tablet pickup device 300 in a disassembled state, and is taken three times in the morning, noon and evening designated by the prescription. It is operated to repeat picking up as many tablets as needed for each dose.
In the above embodiment, the case 2 of the tablet pick-up device 300 circulates on the circular track 303, but instead of the circular track 303, the cases 2 are arranged in a line on a straight guide path, and the case 2 along the guide path. May be moved back and forth.

In the tablet pick-up device 300 of the above embodiment, the case 3 that accommodates the individual package t is a rectangular parallelepiped, and has many through holes 35 that blow out airflow on the entire bottom surface. If a large number of through holes 35 are provided on the entire surface, the air pressure decreases. In order to cope with this, a device having a large pressure is required as a source of air flow. In the embodiment of the tablet pick-up device shown in FIG. 8, the bottom surface of the case is formed in a funnel shape, the area of the bottom surface is reduced, and the locations where the airflow is blown out are concentrated. Also in this example, a tablet with individual packaging t is shown as an example.

In the case 3 shown in FIG. 8, the upper side is opened by the opening 38, while the range 41 in which the through hole 35 through which the airflow is blown out is reduced on the bottom surface, and the range 41 in which the through hole 35 is provided moves upward. Thus, a funnel-shaped slope 42 is provided so as to expand the space, and the individual package t soared falls on the range where the through-hole 35 is provided by dropping on the funnel-shaped slope 42. On the funnel-shaped slope 42, airflow reversing plates 40 are discretely provided at locations slightly above the through holes 35 through which the airflow blows. The airflow reversal plate 40 is formed of a flat resin plate, and the base portion 40a is thinner than the tip portion 40b, and has flexibility so that it does not break even when the individual package t collides. The front end portion 40 b of the airflow reversing plate 40 protrudes directly above the through hole 35. On the other hand, the root portion 40 a of the airflow reversing plate 40 is fixed to a funnel-shaped slope 42. This fixed position is a position away from the through hole 35 and lower than the tip end portion 40 b, and the airflow reversing plate 40 is generally inclined toward the position directly above the through hole 35. The base fixing position of the airflow reversing plate 40 may be the side wall of the case 3 instead of the funnel-shaped slope 42. The air flow is introduced into the air chamber 43 from the right side and ejected from the through hole 35.

The suction device 350 includes a suction nozzle 355, a hood 351, and a lid 352. The inner surface of the hood 351 is a concave curved surface with the position of the suction nozzle 355 as the top. A suction port 358 of the suction nozzle 355 opens at the top of the hood 351. The contact 356 of the sensor 357 is provided in the vicinity of the suction port 358, and outputs a detection signal when the individual package t is caught by the suction port 358. The hood 351 is made of resin or metal having a smooth inner surface. Reference numeral 353 denotes a rod that is connected to the piston of the cylinder 306 in FIG. The lid 352 is fixed to the flange 353 and closes the opening 38 of the case 3. When the suction device 305 is lowered by the cylinder 306 and the suction device 350 is inserted into the case 3 through the opening 38, the inside of the case 3 is closed with a lid 352 so that the individual packaging t is not allowed to pass outside. Constitute.

FIG. 9 shows a state in which the air flow blown out from the through hole 35 is reversed downward. FIG. 9A is a diagram showing the flow velocity when the air flow is ejected from the through-hole 35 in the case 3 in a state where the air flow reversing plate 40 is not provided, and FIG. 9C schematically shows the direction of the air flow. It shows. The air flow ejected from the through-hole 35 flows upward while slightly diffusing. In addition, since the air flow is introduced into the air chamber 43 from the pipe 44 on the right side in FIG. 9A, the air flow ejected from the through hole 35 is ejected more strongly on the left side than on the right side in FIG. 9A.

FIG. 9B is a diagram showing the flow rate when the air flow is ejected from the through-hole 35 in the case 3 in a state where the air flow reversing plate 40 is provided, and FIG. 9D schematically shows the direction of the air flow. Show. The air flow ejected from the through-hole 35 flows upward while slightly diffusing. The airflow reversing plate 40 directs the direction of the diffused airflow downward. The airflow directed downward is lowered along the airflow reversing plate 40 and flows from the side of the through hole 35. 9A, since the air flow is introduced into the air chamber 43 from the right side of FIG. 9A, the jetted air flow is strongly jetted to the left side and rises along the airflow inversion plate 40 on the right side of the through hole 35. In order to create a descending airflow by the airflow reversing plate 40 in the same way on the left and right, the influence of the airflow flowing from the right side of the air chamber 43 may be reduced. For example, the air chamber may be lengthened vertically or an air flow may be introduced from directly below the air chamber 43.

FIG. 10 is a diagram for explaining the operation of the airflow reversing plate 40. FIG. 10A shows a state in which the individual package t is deposited on the case 3 that does not include the airflow reversing plate 40. When the air flow is ejected from the through-hole 35 in this state, the individual package t rises. On the other hand, if this is repeated, the individual packaging t just above the through-hole 35 is blown off, and a state in which no or a large hole is opened occurs (FIG. 10B). When this state occurs, the individual package t cannot be picked up. On the other hand, when the airflow reversing plate 40 is provided as shown in FIG. 10C, the individual packaging t moves due to the airflow reversed downward by the airflow reversing plate 40 and rides on the rising airflow ejected from the through hole 35. The movement of the individual package t propagates to the other individual package t, and the individual package t rises.

In Example 1, when the air flow was blown over the entire bottom surface of the case 3, the curved plate 33 was used so that the air flow blown upward flowed downstream. In the second embodiment, the airflow does not blow out the airflow over the entire bottom surface of the case 3, and there is a portion where the airflow is not blown out. By detouring to a place where there is no blowout, an inverted airflow can be obtained.
In the second embodiment, the individual packaging t in which the PTP tablet sheets are separated is targeted for pick-up, but the tablet pick-up device 300 of the dispensing device 1 can be applied to a packaging device and used as a tablet pick-up device.

In the tablet pickup device of the above embodiment, one suction device 350 is provided in the case 3, but a plurality of suction devices may be provided in the case 3. In FIG. 11A, the four adsorption devices 350 of the second embodiment are arranged in a 2 × 2 matrix, and the lid 362 is shared. The funnel-shaped slope is installed inside the case 3 corresponding to each suction device 350. Each funnel-shaped bottom surface 42 is provided with a through hole 35 through which an air flow is blown out, and a point where air flow reversal plates 40 are provided discretely at positions slightly above the through hole 35 are as follows. Similar to the second embodiment.

FIG. 11B is a diagram illustrating a control flow of the control unit 10 according to the third embodiment. Instead of step S42 in the control flow shown in FIG. 7, steps S45 to S47 are inserted. When the traveling track 303 is moved so that the shelf 304 of the case 3 containing the target capsule-shaped tablet cp is positioned at the top of the traveling track 303 in step S41, the four suction devices 350 are used. And tablet cp is acquired (S45). When the adsorption of the individual packaging t is successful in all of the four adsorption devices 350, it is compared with the required number of fractions of the tablet cp (step S46), and if it is too much, the excess is dropped (step S47). ). For example, when the required number of fractions of the tablet cp is two and the suction device 350 succeeds in suction of the four individual packages t, the excess two are dropped. Moreover, when the adsorption | suction apparatus 350 succeeds in adsorption | suction of the three individual packaging t, one of surplus is dropped. If the adsorbing device 350 cannot adsorb as many as the required number of tablets, it starts again.
In the present embodiment, even if not all of the suction devices 350 succeed in the suction, it is necessary to cause the suction device 350 to perform the suction operation again if the required number of fractions of the tablet cp is sufficient. There is no effect.

Note that a guide plate directed from the edge of the hood 351 toward the suction port 358 may be disposed on the inner surface of the hood 351 of the suction device 350. By arranging the guide plate, it is possible to prevent the tablet cp from rushing to the suction port 358 at random. The guide plate may be used in the

suction devices

305 and 350 according to the first and second embodiments. In the third embodiment, the tablet cp in a disassembled state is targeted, but it is also possible to use it for picking up an individual package t in which PTP tablet sheets are separated.
