Description

  The present invention relates to a drug stock structure of a dispensing device, and is particularly suitable for a drug stock structure of a dispensing device that automatically dispenses a packaged tablet called a PTP (press-through package) tablet sheet into a tablet cassette.

  Traditionally, pharmacists perform dispensing work in pharmacies such as hospitals according to doctors' prescriptions, but in general hospitals where medical fields are wide, there are many types of tablets that can be taken out at all times, and storage locations are limited. Not only was it necessary, but the work of dispensing based on prescriptions was very mentally and physically burdensome.

  Therefore, a dispensing device has been developed that automatically dispenses a predetermined number of predetermined tablets including a fraction of a PTP tablet sheet based on a preset program (see, for example, Patent Documents 1 and 2). The PTP tablet sheet is a packaging form in which the tablet is taken out by breaking the bottom aluminum sheet part by pressing the tablet side. Generally, 10 or more tablets are made into one sheet. Supplied.

  Here, the tablet cassette on which a plurality of PTP tablet sheets are placed is housed in a cassette shelf, and the claw portion of the chucking device mounted on the head device is directly in the groove formed on the front surface of the tablet cassette. Intrusion and relative positioning are performed, and the PTP tablet sheet at the lowest position in the tablet cassette is chucked and taken out to the outside.

In the tablet cassette 1000, as shown in FIG. 16, the width regulating member 1011 separate from the front wall body 1020 regulates the width direction of the unillustrated PTP tablet sheet, while the front wall body 1020 and the rod body 1041 In addition, the longitudinal direction of the PTP tablet sheet is regulated by an integrated body 1040 of the rod base 1042.

  In the above prior art, in order to securely chuck the PTP tablet sheet, it is necessary to align the tablet cassette 1000 and store in a flat stack. For this reason, the stop position of the integrated object 1040 was adjusted according to the length of the PTP tablet sheet.

  Then, a plurality of PTP tablet sheets packed in a box are taken out from the box and are to be loaded in the tablet cassette 1000 as they are. Is extended to the rear by substantially the same dimension, so the left and right side walls are doubled. For this reason, it is possible to quickly replenish and take out the PTP tablet sheet from the space defined by the width regulating member 1011, the front wall body 1020, and the integrated body 1040 of the rod body 1041 and the rod body base 1042. It was difficult.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sheet stacking structure for a dispensing device that can greatly improve the efficiency of replenishment and removal of PTP tablet sheets.

The present invention is a tablet cassette, a bottom surface for stocking chemicals and front wall erected on the front end on the bottom, is erected on the left and right ends on the bottom surface, the chemicals to be transported from the outside a drug stock structure of dispensing device provided with a left and right side walls for guiding the front wall, wherein the rear end of the tablet cassettes toward the front,-out missing off the left and right side wall portions, said left and right side walls Of these, the cutout range on one side is set larger than the cutout range on the other side .

  According to the present invention, since the left and right side walls are partially cut away from the rear end of the tablet cassette toward the front, the medicine is carried in from the notched portions of the left and right side walls. By guiding on both side walls, the medicine can be directly replenished to the tablet cassette, and the medicine replenished to the tablet cassette can be directly removed from the notch of the left and right side walls. Can be taken out. Therefore, it is possible to improve the efficiency of supplementing and taking out medicines from the tablet cassette.

Further, since the cutout range of one of the left and right side walls is set larger than the cutout range of the other side wall, the remaining part of the other side wall of the left and right side walls is the remaining side of the one side. It overhangs from the part that was made. By guiding the medicine to be replenished to the tablet cassette and the medicine to be taken out from the tablet cassette at the protruding portion, it is possible to further improve the efficiency of replenishing the medicine to the tablet cassette and taking out the medicine.

As in the second aspect of the present invention, it is preferable that the range in which the right side wall is cut out from the rear end of the tablet cassette to the front side is set larger than the range in which the left side wall is cut out.

According to invention of Claim 2 , since the range which the notch of the right side wall cuts forward from the rear end of the said tablet cassette is larger than the range which the notch of the left side wall cuts, the part which the left side wall remained However, it protrudes beyond the remaining part of the right side wall. By guiding the medicine to be replenished to the tablet cassette and the medicine to be taken out from the tablet cassette at the protruding portion, it is possible to further improve the efficiency of replenishing the medicine to the tablet cassette and taking out the medicine. In this case, in order to guide the medicine to be replenished to the tablet cassette and the medicine to be taken out from the tablet cassette at the overhanging portion, the user holds the medicine and moves it from the right side to the left side. This is convenient for right-handed people. When a left-handed person uses it, it is sufficient to set the size relationship of the cutout range in the opposite direction.

As in the invention described in claim 3 , it is preferable that the notch range is set so as to extend over approximately half or more of the length of the tablet sheet containing the medicine in the front-rear direction of the tablet cassette.

According to invention of Claim 3 , since the said notch range was set so that it might extend over about half or more of the length of the tablet sheet containing the said medicine in the front-back direction of the said tablet cassette, The medicine can be easily refilled into the tablet cassette through the portion, and the medicine can be easily taken out from the tablet cassette. This also makes it possible to further improve the efficiency of supplementing and taking out medicines from the tablet cassette.

According to the present invention, since the left and right side walls are partially cut away from the rear end of the tablet cassette toward the front, the medicine is carried in from the notched portions of the left and right side walls. By guiding on both side walls, the medicine can be directly replenished to the tablet cassette, and the medicine replenished to the tablet cassette can be directly removed from the notch of the left and right side walls. Can be taken out. Therefore, it is possible to improve the efficiency of supplementing and taking out medicines from the tablet cassette. Further, since the cutout range of one of the left and right side walls is set larger than the cutout range of the other side wall, the remaining part of the other side wall of the left and right side walls is the remaining side of the one side. It overhangs from the part that was made. By guiding the medicine to be replenished to the tablet cassette and the medicine to be taken out from the tablet cassette at the protruding portion, it is possible to further improve the efficiency of replenishing the medicine to the tablet cassette and taking out the medicine.

On 310, a servo motor 410, a ball screw 415 in the horizontal axis direction (X direction in FIG. 1) driven by the servo motor 410, and a nut (not shown) are provided.

  2 is a perspective view of the tablet cassette 500 as viewed from the side facing the chucking unit 400, FIG. 3 is a perspective view showing the dimensional relationship of the main part, and FIG. 4 is a side sectional view showing the state before the sheet cueing. FIG. 5 is a side sectional view showing a state at the time of sheet cueing. In the following, the side of the tablet cassette 500 that faces the chucking unit 400 is referred to as the front, and the opposite side is referred to as the rear.

  The tablet cassette 500 in the present embodiment is formed to be slightly wider than various PTP tablet sheets (corresponding to tablet sheets) 900 to be stacked. Accordingly, a plurality of tablet cassettes 500 having different width dimensions are prepared according to the widths of various PTP tablet sheets 900. As shown in FIGS. 2 and 3, the specific configuration thereof is a long cassette base 510 having a concave cross section, and a cassette body 520 that is detachably fitted from the longitudinal direction of the cassette base 510. It is made up of.

  As shown in FIGS. 4 and 5, L-shaped protrusions 512 and 512 are formed in the front and rear (and left and right) sides on the back side of the bottom plate 511 of the cassette base 510, and the rear end of the bottom plate 511 is A tongue piece 513 that is bent upward and has elasticity is formed. A support member 514 having a reverse concave shape in cross section is formed on the surface side of the rear portion of the bottom plate 511, and two left and right tongue pieces 515 and 515 that are cantilevered by the support member 514 are respectively formed so as to descend toward the front portion. Has been. As shown in FIG. 2, the support member 514 and the tongue pieces 515 and 515 are both disposed in the left and right side walls 516 and 517 of the cassette base 510, and the tongue pieces 515 and 515 serve as PTP tablet sheets. A fraction of 900, 900,... Is chucked. However, the number of the strips 515 is not limited to two but may be one or three or more.

  The cassette main body 520 further includes a main body upper part 530 on which a plurality of PTP tablet sheets 900, 900,... Can be stacked, and a main body lower part 540 attached integrally with the lower part of the main body upper part 530. .

  The main body lower part 540 is arranged in a state where the cassette main body 520 is assembled to the cassette base 510 and is buried in the left and right side walls 516 and 517 of the cassette base 510. A link mechanism (not shown) for sequentially taking out the PTP tablet sheets 900 stacked at the bottom of the main body upper portion 530 is provided on the bottom plate 541 having a long shape.

  As shown in FIG. 2, the main body upper part 530 is embedded in the left and right side walls 516 and 517 of the cassette base 510 from the rear part to the intermediate part in the assembled state of the cassette main body 520 to the cassette base 510, It has an L-shape in a side view and protrudes above the left and right side walls 516 and 517 of the cassette base 510 from the front to the front, and the protruding left and right side walls 5311 and 5312 are bent inward at the front end. Thus, the front wall 531 is formed by being opposed to each other through a predetermined gap. The upper ends of the left and right side walls 5311 and 5312 are connected to each other by a reinforcing plate 532.

  In other words, the main body upper portion 530 is carried toward the front of the tablet cassette 500 between the left and right side walls 5311 and 5312 integrally connected to the front wall 531 erected on the bottom surface 5301 of the tablet cassette 500. A tablet sheet (not shown) can be stacked on the bottom surface 5301.

  As shown in FIG. 3, the left and right side walls 5311 and 5312 are partially cut out from the rear end of the tablet cassette 500 to the front, and the right side wall 5311 from the rear end of the tablet cassette 500 to the front. The cutout range S1 is set larger than the cutout range S2 of the left side wall 5312. In this case, the front-rear dimension W1 of the right side wall 5311 is smaller than the front-rear dimension W2 of the left side wall 5312.

  Hereinafter, the usage method of this tablet cassette 500 is demonstrated. 6 is a perspective view showing how the PTP tablet sheets 900, 900,... Are replenished to the tablet cassette 500, and FIG. 7 is a perspective view showing a state where the replenishment is completed.

  First, as shown in FIG. 6, when the PTP tablet sheets 900, 900,... Are refilled in the upper body 530, the user holds the PTP tablet sheet 900 from the back of the tablet cassette 500. Then, it is moved from the right side toward the left side (the direction A in FIG. 6). Next, when the PTP tablet sheet 900 comes into contact with the left side surface 5312, the PTP tablet sheet 900 is guided from the rear side of the tablet cassette 500 while being held by the user (see FIG. 6 in the B direction).

  Then, as shown in FIG. 7, the PTP tablet sheet 900 can be accurately replenished into the main body upper portion 530. The replenishment method of the PTP tablet sheet 900 according to this procedure is convenient when a right-handed person uses the PTP tablet sheet 900 because the user moves the PTP tablet sheet 900 from the right side to the left side of the tablet cassette 500. When the left-handed person uses the PTP tablet sheet 900, the size relationship of the notch range is reversed so that the user can move the tablet cassette 500 from the left side to the right side by hand. Setting is sufficient.

  When taking out the PTP tablet sheets 900, 900,... From the main body upper part 530, the procedure is the reverse of the case shown in FIGS. That is, as shown in FIG. 7, the PTP tablet sheet 900 replenished in the main body upper part 530 is moved in the direction opposite to the B direction in FIG. Next, the PTP tablet sheet 900 is moved in the direction opposite to the A direction in FIG. In this way, the PTP tablet sheet 900 can be quickly taken out from the main body upper part 530.

  The cutout ranges S1 and S2 are set at positions higher than the maximum height H of the PTP tablet sheet 900 that can be placed at the bottom of the tablet cassette 500.

  Therefore, the PTP tablet sheet 900 in the lowest position in the tablet cassette 500 is guaranteed to be aligned in the remaining portions of the left and right side walls 5311 and 5312, so that the PTP tablet sheet 900 in the lowest position can be reliably It can be chucked and taken out.

  Further, the cutout ranges S1 and S2 are set so as to cover approximately half or more of the length of the tablet cassette 500 in the front-rear direction of the tablet cassette 500.

  Therefore, the PTP tablet sheet 900 can be easily replenished into the tablet cassette 500 through the large cutout ranges S1 and S2, and the PTP tablet sheet 900 can be easily taken out from the tablet cassette 500.

  8 is a perspective view showing a state in which a horizontal bridge of the PTP tablet sheet 900 is generated in the upper part 530 of the main body of the tablet cassette 500, FIG. 9 is a perspective view in which the rod-like member 533 is omitted in FIG. It is a side view when the right and left side walls 5311 and 5312 of the main body upper part 530 are made into the linear shape of the front rising.

  By the way, when the upper ends P and Q of the remaining part where the left and right side walls 5311 and 5312 are cut out are parallel to the PTP tablet sheet 900, the PTP tablet sheet 900 and the upper ends P and Q of the remaining parts are Line contact. This tendency to be in line contact is particularly prominent when the cutout ranges S1 and S2 are set so large that they extend over approximately half the length of the tablet cassette 500 in the front-rear direction of the tablet cassette 500.

  For this reason, as shown in FIGS. 8 and 9, either the left or right side of the PTP tablet sheet 900 rides on the upper ends P and Q of the remaining portion and becomes laterally inclined, and this PTP tablet sheet 900 is placed in the tablet cassette 500. A so-called horizontal bridge of the PTP tablet sheet 900 that is not stored in a predetermined position in the main body upper portion 530 is likely to occur. The occurrence of the horizontal bridge makes it difficult for an extruding member (not shown) to be applied to the rear end of the lowermost PTP tablet sheet 900, which may impede the dispensing of the PTP tablet sheet 900 from the tablet cassette 500. It was.

  In order to eliminate such inconvenience, as shown in FIG. 10, when the left and right side walls 5311 and 5312 are partially cut away from the rear end of the tablet cassette 500 to the front, It is preferable to linearly incline the upper end P (in the figure, Q overlaps with P) so as to rise forward.

  However, if the inclination angle is too small, the PTP tablet sheet 900 and the upper ends P and Q of the remaining portions may not be in point contact due to the bending of the PTP tablet sheet 900 or the like. It is difficult to prevent the occurrence of horizontal bridges.

  On the other hand, if the inclination angle is too large, it becomes difficult to secure the cutout ranges S1 and S2 of the left and right side walls 5311 and 5312. Therefore, replenishment of the PTP tablet sheet 900 to the tablet cassette 500 and the tablet cassette 500 There is a possibility that the efficiency of taking out from the product may decrease.

  Therefore, the inclination angle is about 9 to 18 degrees with respect to the bottom plate 5301 (see FIG. 2) of the main body upper portion 530 of the tablet cassette 500 on which the PTP tablet sheet 900 is loaded in a substantially horizontal state. It is preferable to adopt one.

  In this way, since the PTP tablet sheet 900 and the upper ends P and Q of the remaining portions are in point contact, it is difficult for the PTP tablet sheet 900 to ride on the upper ends P and Q of the remaining portions of the left and right side walls 5311 and 5312. Thus, the PTP tablet sheet 900 is stored in a predetermined position by its own weight, and thus the occurrence of the horizontal bridge of the PTP tablet sheet 900 is surely prevented. At the same time, it is possible to secure the cutout ranges S1 and S2 of the left and right side walls 5311 and 5312 so as to improve the efficiency of replenishment of the PTP tablet sheet 900 to the tablet cassette 500 and removal from the tablet cassette 500. it can.

  The angle should be determined according to the length of the tablet sheet loaded on the tablet cassette, and the angle of about 9 degrees corresponds to the longest sheet, and the angle is about 18 degrees. The thing corresponds to the shortest sheet.

  FIG. 11 is a side view in which the left and right side walls 5311 and 5312 of the upper part 530 of the main body of the tablet cassette 500 are curved upward, and FIG. 12 shows the case where the PTP tablet sheet 900 loaded in the tablet cassette 500 is the longest sheet. FIG. 13 is an explanatory diagram showing (before sheet removal), FIG. 13 is an explanatory diagram showing the case where the PTP tablet sheet 900 loaded in the tablet cassette 500 is the shortest sheet (before sheet removal), and FIG. 14 is a PTP loaded in the tablet cassette 500 FIG. 15 is an explanatory diagram showing a case where the tablet sheet 900 is the longest sheet (when the sheet is taken out), and FIG. 15 is an explanatory diagram showing a case where the PTP tablet sheet 900 loaded in the tablet cassette 500 is the shortest sheet (when the sheet is taken out). In each figure, the linear slope P and the extended side wall (described later) PB of the tablet cassette 500 are shown for reference.

  When the PTP tablet sheet 900 is stacked in the tablet cassette 500, the PTP tablet sheet 900 may be the longest sheet as shown in FIG. 12 or the shortest sheet as shown in FIG.

  When the PTP tablet sheet 900 is chucked by the chucking unit 400, the next PTP tablet sheet 900 falls by its own weight after passing the center of gravity in the sheet length direction. This is the previous PTP tablet. It rides on the rear end of the seat 900 and tilts, causing the horizontal bridge described above.

  The inclination angle is not constant. As shown in FIGS. 14 and 15, the higher the sheet height of the PTP tablet sheet and the shorter the sheet length, the larger the inclination of the next PTP tablet sheet. In that case, the difference in sheet height is negligible, but the sheet length is greatly different, and it is actually difficult to cope with both the longest sheet and the shortest sheet with the same tablet cassette 500.

  However, if an inclined straight line is formed with respect to the shortest sheet (the most inclined tablet sheet), the left and right wall surfaces 5311 and 5312 become large, and the workability of replenishing and taking out the PTP tablet sheet 900 from the tablet cassette 500 is increased. May be damaged.

  In order to eliminate such inconvenience, as shown in FIG. 11, when the left and right side walls 5311 and 5312 are partially cut away from the rear end of the tablet cassette 500 to the front, It is preferable to incline the upper end PA in a curved manner so as to rise upward.

  By doing so, the inclination angle is increased for the shortest sheet and the inclination angle is decreased for the longest sheet. As a result, the left and right wall surfaces 5311 and 5312 are compared to the case of the inclined straight line. Thus, the workability of replenishing and taking out the PTP tablet sheet 900 from the tablet cassette 500 can be improved. Further, in this case, regardless of the length of the PTP tablet sheet 900, the PTP tablet sheet 900 and the upper ends PA and QA (overlapping PA in the figure) of the remaining portion are always on. Contact. For this reason, it becomes difficult for the PTP tablet sheet 900 to ride on the upper ends PA and QA of the remaining portions of the left and right side walls 5311 and 5312, and the occurrence of the horizontal bridge of the PTP tablet sheet 900 is more reliably prevented. Such a configuration can be realized easily and inexpensively.

  Here, the inclination curve is, for example, about a first straight line forming about 9 degrees (corresponding to a first inclination angle) with respect to the bottom plate 5301 of the main body upper portion 530 of the tablet cassette 500 and the bottom plate 5301. For example, what is necessary is just to envelop the 2nd straight line | wire which makes about 18 degree | times (equivalent to a 2nd inclination angle). Such a configuration can be realized more simply and inexpensively.

  Note that both the first and second inclination angles need only be in the range of about 9 to 18 degrees, and are not necessarily limited to about 9 degrees and about 18 degrees. Further, the second straight line having a second inclination angle larger than the first inclination angle with respect to the bottom plate 5301 of the main body upper portion 530 of the tablet cassette 500 is not limited to a single straight line. Good. For example, by increasing the second straight line in which the second inclination angle is changed in small increments and enveloping them with the first straight line forming the first inclination angle, a more complete curved shape can be obtained. .

  A rod-like member 533 is erected on the rear part of the upper part 530 of the main body, and is laid down when the PTP tablet sheets 900, 900,. The PTP tablet sheets 900, 900,... Are aligned by raising the rod-like member 533 with the PTP tablet sheets 900, 900,. Thereby, the operation | work which replenishes the PTP tablet sheet 900 in the main body upper part 530 can be performed efficiently.

  Further, even when the PTP tablet sheet 900 is taken out from the upper part 530 of the main body, the work can be efficiently performed by laying down the bar member 533.

  As shown in FIG. 1, the chucking unit 400 includes a Z carriage 411 extending forward (Z direction in FIG. 1) from the carriage body 310, a rotary solenoid 420 disposed on the Z carriage 411, and the rotary solenoid 420. Chuck 430 driven by the horizontal axis, horizontal guides 440 and 440 respectively disposed on the left and right sides of the chuck 430, a primary bucket 450 provided at a lower portion between the horizontal guides 440 and 440, and a front portion of the primary bucket 450 A line sensor 460 provided and a secondary bucket 480 with a shutter 470 provided below the primary bucket 450 are provided. The Z carriage 411 is composed of a servo motor (not shown), a ball screw, and a nut.

  If it is not necessary to punch the fraction of the PTP tablet sheet 900, the chuck 430 of the chucking unit 400 moves forward in response to an operation command from a controller (not shown), and the chuck 430 directly uses the tablet cassette. By pressing the pressing member 543 of 500, the pushing member (not shown) is moved forward by the function of the link mechanism 550.

  By pressing the rear end of the PTP tablet sheet 900 loaded on the lowermost side of the tablet cassette 500 with the moved extruding member, the front end of the PTP tablet sheet 900 slightly protrudes from the tablet cassette 500. From the state shown in FIG. 4 to the state shown in FIG. 5, so-called cueing is performed. The chucked PTP tablet sheet 900 is chucked by the chuck 430 and pulled forward, and chucking by the chuck 430 is released to drop the pulled PTP tablet sheet 900 into the primary bucket 450. The primary bucket 450 is moved onto the secondary bucket 480 using the X carriage 300 and the Y carriage 200. Then, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheet 900 is dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheet 900 is dropped onto the transport conveyor unit 800.

  The cutting unit 700 includes a vertical blade and a horizontal blade (not shown) for punching out the fraction of the PTP tablet sheet 900. Even when it is necessary to punch out the PTP tablet sheet 900, as described above, the pressing member 543 of the tablet cassette 500 is pressed by the chuck 430 of the chucking unit 400, and the pushing member is directed forward by the link mechanism. Move to.

  By pressing the rear end of the PTP tablet sheet 900 loaded on the lowermost side of the tablet cassette 500 with the moved extruding member, the PTP tablet sheet 900 is cued. The chucked PTP tablet sheet 900 is chucked by the chuck 430 and pulled forward, and this time, the pulled PTP tablet sheet 900 is transported to the cutting unit 700 while being chucked. Then, the PTP tablet sheet 900 is punched by using the vertical blade and the horizontal blade, and the PTP tablet sheet 900 corresponding to the punched fraction is dropped directly onto the transport conveyor unit 800.

  The remaining part of the PTP tablet sheet 900 that has been punched out is returned to the original tablet cassette 500 while being chucked by the chuck 430. In this case, the remaining part of the PTP tablet sheet 900 is the tongue of the cassette base 510. It is inserted and stored in the remaining storage section 515a below the pieces 515, 515 in a cueing state.

  The remaining portion of the PTP tablet sheet 900 stored in the remaining storage portion 515a is then chucked by the chuck 430 with the remaining portion of the PTP tablet sheet 900 and pulled forward, and is formed by the line sensor 460. Check. Then, when it is not necessary to punch out the remaining part of the PTP tablet sheet 900, the chucking by the chuck 430 is released in order to drop the remaining part of the PTP tablet sheet 900 into the primary bucket 450. The primary bucket 450 is moved onto the secondary bucket 480 using the X carriage 300 and the Y carriage 200. Next, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheet 900 is dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheet 900 is dropped onto the transport conveyor unit 800.

  On the other hand, even when it is necessary to punch the remaining fraction of the remaining portion of the PTP tablet sheet 900, as described above, the chuck 430 can cue it from the remaining portion storage portion 515a under the tongue pieces 515 and 515 of the cassette base 510. The remaining portion of the PTP tablet sheet 900 is chucked and pulled forward. The remaining portion of the pulled PTP tablet sheet 900 is conveyed to the cutting unit 700 while being chucked. Then, the remaining part of the PTP tablet sheet 900 is punched using the vertical blade and the horizontal blade, and the PTP tablet sheet 900 corresponding to the further punched part is dropped directly onto the transport conveyor unit 800.

  On the other hand, the remaining part of the PTP tablet sheet 900 that has been subjected to further blanking is returned to the original tablet cassette 500 while being chucked by the chuck 430.
