BACKGROUND OF THE INVENTION In recent years, dispensing work in pharmacies such as hospitals has been carried out manually by pharmacists and the like, and the frequency of dispensing various tablets containing inner capsules of these drugs is increasing. This tablet is called a PTP tablet sheet, and it is a packaging format in which the tablet side is pressed to break the aluminum sheet at the bottom and take out the tablet. Generally, 10 or more tablets are packed in one sheet. Supplied in sheet form.

[0003] Pharmacists dispense this PTP tablet sheet to patients based on a doctor's prescription, but especially in general hospitals with a wide range of medical fields, there are many types of tablets that can be taken out at any time. There are more than 600 types, and not only do they require storage space, but the task of dispensing drugs based on prescriptions is extremely taxing both mentally and physically.

[0004] Therefore, one of the co-applicants of the present application has filed an application for a ``device for taking out blister packaging'' to provide a proposal for automating dispensing. When this proposal is organized in accordance with the language of the present application, it consists of a case shelf partitioned into multiple stages vertically and horizontally, and a tablet case that is housed in the case shelf and has a remaining number storage section that accommodates fractions of tablet sheets. , a discharge box disposed on the side surface of the case shelf, an XY carriage for moving vertically and horizontally on the front surface of the case shelf, and a head device installed on the XY carriage; a) the head device is connected to the case; a positioning mechanism for positioning with respect to the shelf;
b) A cutter device having vertical and horizontal blades for cutting off fractions of the tablet sheet, c) A holding device for a vacuum pump to prevent the tablet sheet from moving during cutting, and d) A gripping device for gripping the edges of the tablet sheet. and e) a Z-shape for gripping the tablet sheet with a gripping device and moving it in the Z direction to take out the tablet sheet from the tablet case and return it to the remaining number storage section after cutting the tablet sheet into fractions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the dispensing device will be described below in detail with reference to the drawings. (Overall Configuration) FIG. 1 is an external perspective view of a dispensing device according to an embodiment, and the front left side of the device is partially cut away due to space constraints.

In FIG. 1, the entire dispensing device has a substantially U-shaped planar projection shape, and each component described below is constructed by welding and screwing angle members etc. By attaching a cover member (not shown) to the frame 100 in a removable manner from the outside, the external dimensions can be reduced to 1.8 m in height and 1 m in width.
．． It is 8m long and 1.2m deep, reducing the occupied floor space.

A total of 140 tablet cases 200 are placed on case shelves 105 provided on opposite sides of the U-shaped frame 100 as shown in the figure.
However, in the case of standard specifications) is provided in a detachable manner. A large number of the above-mentioned PTP tablets are stored in these tablet cases 200 in a vertically stacked manner. As shown in the figure, the case shelves 105 are arranged in five stages vertically, and on these case shelves 105 there are binaries for inserting and setting the pill cases 200 in predetermined positions to prevent incorrect insertion. A pin that constitutes a value is provided, and by matching with a groove provided in the tablet case 200, it is possible to reliably prevent incorrect insertion.

[0011]Although these tablet cases 200 are inserted and fixed into predetermined positions on the case shelf 105 from the outside of the device, only the case portion described below that can be attached to and detached from the tablet case 200 after being fixed is attached. By making it possible to remove a predetermined PTP tablet sheet, it is possible to replenish a predetermined PTP tablet sheet. The configuration of this tablet case 200 will be described later.

The tablet case 200 configured as described above allows the user to attach and detach all the tablet cases 200 by opening and closing the sliding door 101 that can be opened laterally on the outside of the frame 100. As shown in the figure, the tablets are arranged adjacent to each other without any gaps, making it possible to accommodate the maximum number of tablets. Further, a door switch 119 is provided at the lower edge of the sliding door 101, and monitors the opening/closing state of the sliding door to prevent operation of the device in the open state.

Next, heads 400 are provided on the mutually opposing side surfaces of the case shelf 105, which are driven along the side surfaces in the X and Y arrow directions in the figure. In order to make the head 400 movable vertically and horizontally, the head 400 is made vertically movable along the Y rail 303 provided below the XY carriage 300, while the XY carriage 300 is moved from the ceiling of the frame 100. It is guided by an X rail 302 provided in the section.

Therefore, the Y carriage motor 301 that drives the head 400 in the vertical direction is replaced by the XY carriage 30.
The X-carriage motor 305 that drives the XY-carriage 300 in the direction of the X arrow is mounted on the frame 10.
It is fixed to the right end of 0. Case shelf 1 like this
05, the head 400 is moved vertically and horizontally.
A chucking claw, which will be described later, is provided, and after the head 400 moves to a position facing a predetermined tablet case 200, the claw inside the head 400 moves in the direction of the Z arrow in the figure to move the tablet from the tablet case 200 as described above. The PTP tablet prepared is taken out and stored in a storage section provided below the head 400.

While maintaining this state, the head 400 is moved directly above the discharge box 601 located on the right side of the figure, and the PTP tablet is dropped into the discharge box 601. A third drop lid 602, which will be described later, is provided at the bottom of the discharge box 601, and the PTP tablets are dropped onto the conveyor 300 by sliding the third drop lid 602. This conveyor 300 is capable of conveying PTP tablets in the front-rear direction in the figure, and conveys the PTP tablets to a first tablet take-out box 603 at the front or a second tablet take-out box 605 at the back and drops them.

With the above configuration operation, the tablet case 20
The PTP tablets selected in 0 are transported to the first tablet take-out box 603 and handed to the patient, while the PTP tablets transported to the rear second tablet take-out box 605 are not compatible with the prescription. This prevents accidents from being treated as defective and not being given to patients. Next, the PTP tablets to be taken out from the tablet case 200 are stored in a plurality of overlapping sheets each containing, for example, 10 tablets, and the PTP tablets are taken out with a nail as described above. However, for example, when dispensing 3 PTP tablets per day for one week, it is necessary to take out 3 x 7 = 21 tablets, which means that it is necessary to cut out 1 tablet from a sheet of 10 tablets. occurs.

[0017] In the figure, the cutter 500 provided at an intermediate height position on the right side of the frame 100 is provided for cutting the above-mentioned required number of tablets from the PTP tablet sheet, and its configuration will be described later. As shown in the figure, one unit is disposed at each position along the side surface formed by the five case shelves 105. The above-mentioned discharge box 601 is located below the cutter 500, and the cutter 500
The tablets cut by 0 are dropped into the discharge box 601.

Further, the remaining portion of the PTP tablet sheet from which the fraction has been cut is returned to the remaining number storage section provided at the bottom of the dispensing case 200, and the remaining number is determined based on the type of PTP tablet, placement position, It is stored and stored in a storage unit of a control terminal device, which will be described later, together with information on the number of objects. A drawer-type controller 700 is provided below the case shelf 105 of the frame 100, and controls the drive of each component described later based on a control command from a control terminal device.

Here, in the explanation of the above-mentioned dispensing device based on FIG.
Although we have described an example of a configuration in which two case shelves 105 are provided, in order to prevent the entire device from falling down,
There is no need to provide two rows of rows, and one row may be sufficient. By the way,
The configuration in which two rows of case shelves 105 are provided in parallel follows the configuration of conventional dispensing case shelves manually constructed by pharmacists, and can be used without any discomfort by pharmacists who are accustomed to conventional dispensing case shelves. This takes into consideration the installation area. Here, the case shelves 105 are not limited to two rows,
Of course, more tablets can be handled by arranging more tablets in parallel and communicating with each other via the conveyor 600. (Explanation of each type of PTP tablet sheet) Fig. 2 is a plan view of each type of PTP tablet sheet. A PTP tablet sheet A having an ear portion 2, a PTP tablet sheet B having a tablet portion 5 for 20 tablets, and a vertical perforation portion 3 and a horizontal perforation portion 4; A PTP tablet sheet C which is provided with a tablet portion 5 and has a vertical perforation portion 4 and a horizontal perforation portion 3.
The state of each is shown.

These PTP tablet sheets A, B, and C are attached to the lower claw body 401, the upper right claw body 410, and the upper left claw body 4, which are chuck claws provided on the head 400 mentioned above.
12 respectively grasp the center position along the longitudinal direction. PTP tablet sheet A is convenient because the ears 2 can be gripped exactly, but PTP tablet sheet B does not have ears, so a small part of the edge of the sheet 1 can be gripped with a claw as shown in the figure. The handle must be gripped by the edges, but as shown in the figure, only a small amount of the edge is gripped.

[0021] In addition, the PTP tablet sheet C generally has an ear part 2.
In many cases, the tablet name and manufacturing company name are printed on this part, and the center part of this PTP tablet sheet C is similarly gripped by the claws as shown in the figure. . If the PTP tablet sheet thus gripped by the claws does not need to be cut into fractions, it is conveyed to the first tablet take-out box 603 etc. via the discharge box 601 as described above.

On the other hand, when cutting out only one tablet part 5 from the PTP tablet sheet A, for example, after punching out the vertical cut part 7 along the vertical perforation part 4 as shown in the figure, a horizontal perforation machine is used. A transverse part 8 is punched out along the eye part 3. As shown in the figure, the vertical cut portion 7 and the transverse portion 8 are punched out in excess at their intersections to ensure that the punching is performed reliably.

[0023] In addition, when cutting four tablet parts 5 from the PTP tablet sheet B, it is necessary to punch out the horizontal parts 8 at one time along the horizontal perforations 3 as shown in the figure. The cut portion 8 has a sufficient overall length. And P before punching
When cutting seven tablet parts 5 from the TP tablet sheet C as shown in the figure, after punching out the vertical cut parts 7 along the vertical perforations 4 as shown in the figure, cut out the horizontal perforations 3. The cross section 8 is punched out twice along the lines so that the gripped state can be maintained.

Furthermore, when cutting off the PTP tablet sheet C, leaving only one tablet part 5 as shown in the figure,
After grasping with the lower claw body 401, the upper right claw body 410, and the upper left claw body 412 as shown in the solid line diagram, and punching out the vertical cutting part 7 along the vertical perforation part 4 with a cutter described later,
A horizontal portion 8 is punched out along the horizontal perforation 3. After this, only the right upper claw body 410 is independently separated from the lower claw body 401 and is gripped only by the lower claw body 401 and the left upper claw body 412 and moved in the Z direction in the figure to remove one tablet part 5. While grasping only the tablet portion 5 remaining on the cutter, the tablet portion 5 remaining on the cutter is removed by a sweeper of the cutter, which will be described later. Next, the lower nail body 401
Then, the upper right claw body 410 and the upper left claw body 412 are moved to the positions shown by broken lines and gripped again.

As described above, the punching order is such that the tablet part 5 does not fall off from the PTP tablet sheet, and
Consideration has been taken to enable punching even when the number of tablet parts 5 remaining from the PTP tablet sheet becomes small and the claws are at a position where they interfere with the punching part of the cutter 500. (Structure of upper and lower claw bodies) (a) in Figure 3 shows the upper and lower claw bodies and PTP.
It is an external perspective view of a tablet sheet, and is the above-mentioned head 400.
The lower claw body 401, the upper right claw body 410, and the upper left claw body 412 for chucking are moved in the Z arrow direction in the figure to grasp the ear part 2 of the PTP tablet sheet A from above and below. I have to.

[0026] Here, since the PTP tablet sheet A tends to warp toward the tablet 5 side during heat packing,
For this correction, the lower claw parts 403 and 405 of the lower claw body 401
In the figure (
It is best to make it slightly inclined as shown in the side view of b). The upper right claw body 410 is independently driven with respect to the lower claw body 401, the claw portion 411 of the upper right claw body 410 which is the left upper claw body 412 and is the other side for gripping, and the claw portion of the upper left claw body 412. 413 is also formed with a slight inclination in the shape of a "V".

The lower claw portion 403 of the lower claw body 401 described above,
An opening 402 is formed between the openings 405 to allow the PTP tablet sheet to fully penetrate into the cutter 500 when punching out the vertical cut portion 7 with the cutter 500.
This makes it possible to sufficiently sneak into the tablet case 200 even when the remaining portion is returned to the tablet case 200. A hole 406 is bored in the lower claw portion 405 of the lower claw body 401 configured as described above, and a light receiving and emitting sensor 407 is built inside, thereby making it possible to detect the gripping state.

With the upper and lower claws configured as described above, the PTP tablet sheet which has a tendency to warp on the tablet portion 5 side can be flattened, and the gripping state can be detected, and the upper claws can be driven independently. After punching out a fraction from a tablet sheet, it can be grasped if it is not possible to grasp it with both claws. (Structure of a tablet case) FIG. 4 is a perspective view of a tablet case, in which one of the many tablet cases 200 fixed to the case shelf 105 of the frame 100 is connected to the upper right claw body 410,
It is a diagram showing the upper left claw body 412 and the lower claw body 401 together so that the mutual positional relationship can be seen.

In this figure, a tablet case 200 is composed of a mounting base 201 fixed on a case shelf 105, and a case part 202 that is slidable in the longitudinal direction of this mounting base 201 and is detachable. , PTP tablet sheets A, B, C, . . . explained in FIG. 2 are placed inside the case portion 202.
are stored one on top of the other. Further, inside the mounting base 201, a remaining number storage section 203 for storing the remaining number of PTP tablet sheets described above is provided with an opening toward the claw body as shown in the figure. ing.

As explained based on FIG. 1, since the tablet cases 200 are mounted on the case shelf 105 so as to be adjacent to each other without any gaps, the side surfaces of the mounting base 201 and the case portion 202, which are the side surfaces of the tablet case 200, are flush as shown. In addition, since they are mounted adjacent to each other without any gaps in this way, the stopper 106 having a circular flange portion provided for fixing one end of the mounting base 201 to the case shelf 105 can be attached to the stopper 106 as shown in the figure. It is hung at the semicircular part so that it can be used for two cars. The other end of this mounting base 201 is the sliding door 101 described above.
A pair of knurled screws 209 are provided on the left and right in the part that can be operated by opening and closing.
Both ends of the mounting base 201 are fixed to the case shelf 105 by screwing them into the female screw portions 108 shown in broken lines of a fixing bar 107 which also serves as reinforcement and which is fixed to the case shelf 105.

The case shelves 105 for fixing the mounting base 201 in this way are arranged in five levels vertically as described above, and on these case shelves 105, there are no tablet cases 20.
A predetermined combination of the eight pins 106 shown by broken lines constituting a binary value for making it possible to mount 0 in a predetermined position is provided, and the bottom member 223 of the remaining number storage section 203 of the mounting base 201 is provided. By matching the groove 215 formed in the groove 215, it is possible to reliably prevent incorrect attachment.

[0032] Also, the bottom member 223 of the remaining number storage section 203
A pair of width regulating members 204 are provided on the top, which can be adjusted to match the width dimension of the PTP tablet sheet and then fixed, while pressing and holding the tablet part 5 of the PTP tablet sheet from above with a light force. An elastic spring 207 is provided from the ceiling of the remaining number storage section 203. Next, as explained with reference to FIG. 2, the PTP tablet sheets A, B, C, ... have different external dimensions including height, but the external dimensions of the tablet case 200 are all made the same. Since the PTP tablet sheet is manufactured in large quantities by molding, etc., the case portion 202, which accommodates the PTP tablet sheet from the top indicated by the arrow D2 in FIG. 4, can be adjusted to match the external dimensions of the PTP tablet sheet. , and is configured to be detachable from the mounting base 201 described above.

That is, as shown in FIG.
Grooves 230 are formed in the base member 210 of 02, and by matching with pins (not shown) fixed on the mounting base 201, the above-mentioned case shelf 105 and the mounting base 201 are matched. This method also prevents incorrect insertion. On the bottom surface of the base member 210 of this case portion 202, a hooked portion that is hooked to a sliding latch member (not shown) provided on the mounting base 201 is fixed, while a stopper portion 211 (illustrated) is attached to the bottom surface of the base member 210 of the case portion 202. A lock 208 affixed to member 210 holds it in the position shown.

Next, the PTP tablet sheets A, B, C, . . . explained in FIG. A pair of width regulating members 213 are provided inside the illustrated outer wall body 212 having the body 210 as a base. These width regulating members 213 are fixed by screws 216 inserted into elongated holes drilled in the front wall body 214. After loosening these screws 216, the width regulating members 212 are inserted into the PTP tablet shell. By providing a gap in the width of the sheet and fixing it, the width direction of all PTP tablet sheets can be regulated. Further, in order to regulate the longitudinal direction of the PTP tablet sheet, the front wall 214 regulates the front end portion of the PTP tablet sheet including the ears 2, while the rear end is placed on the base member 210 in the longitudinal direction. It is regulated by an integrated rod body 224 and a rod base 225 that are movable in the direction.

This integrated body can be adjusted by tightening a screw 216 shown in the figure, so that the longitudinal direction of all PTP tablet sheets can be regulated. Further, at the center of the rod base 225, a take-out portion 2 of a take-out member 205, which will be described later, is provided.
A recess 233 into which PTP tablet sheet 06 is inserted is formed so that the PTP tablet sheet placed on the lowest stage can be taken out from an opening 220 opened below the front wall body 214. On the other hand, a tongue body 218 is provided above the opening 220 of the front wall body 214 so as to be adjustable in the vertical direction with a screw 216, and once the height of the tablet portion 5 of the PTP tablet sheet is regulated. The two PTP tablet sheets are prevented from being ejected at the same time.

A rear wall 226 is integrally hung on the side of the base member 210 opposite to the front wall 214 as shown in the figure, and a handle 22 fixed to the rear wall 226 is attached to the rear wall 226 .
7 in the direction of arrow D1, the lock 208 is released and the case portion 202 is taken out. after that,
A predetermined number of PTP tablet sheets are stored in the case portion 202 from the direction of arrow D2.

Next, in order to push out the PTP tablet sheet located at the lowest stage from the opening 220 toward the upper and lower claw bodies, the ejecting member 205 is provided with a portion protruding from the remaining number storage section 203. The ejecting member 205 is pressed by a pin 436 of a pusher 435 provided on the head 400 described above.

[0038] This take-out member 205 is attached to the remaining number storage section 20.
The return spring 22 is movable in the longitudinal direction of 3.
9, the remaining number storage section 2 is placed in the position shown in the figure.
A portion protrudes from 03, and its position is regulated by a stopper (not shown). This take-out member 20
A take-out part 206 integrally formed at the rear end of the take-out member 205 is adjustable in the longitudinal direction of the take-out member 205.
It is possible to adjust the longitudinal direction of the PTP tablet sheet.

When the ejecting member 205 described above is pressed by the pusher 435 mounted on the head 400, the ejecting portion 206 retreats into the recess 233, and as a result, the PTP tablet cylinder located at the lowest stage is removed. - The tray falls under its own weight, and its rear end catches the take-out portion 206. After this, when the pusher 435 is retracted from the take-out member 205, the take-out member 205 returns to its original position due to the action of the return spring 229 provided on the take-out member 205. Since the rear end of the PTP tablet sheet is hooked, the above-mentioned ear portion 2 of the PTP tablet sheet will now come out from the opening 220.

[0040] As described above, the PTP tablet sheets located at the lowest stage are sequentially fed out from the opening 220, so the upper and lower claws grip the ears 2, etc., and proceed to the next process. . Above the front wall 214 is a square marker 22.
2 and a right-angled triangular marker 221 are painted or printed, and these are detected by a position detection sensor mounted on the head 400 to determine the relative position of the head 400 with respect to the tablet case 200. (Configuration of XY Carriage) Next, FIG. 5 is a side view of the XY carriage 310 schematically explained in FIG. It is a diagram.
