  FIG. 3 is a view showing the internal structure of the tablet taking-out unit 1. FIG. 3 shows an example in which two tablet taking-out units 1 are arranged side by side.

  The tablet take-out unit 1 includes an input port 203 (input unit) in which a plurality of tablet sheets 51 can be stacked and input in a state where the tablet storage unit 510 is on the upper side with respect to the direction of gravity, and a conveyance mechanism that conveys the tablet sheet 51 16, a mounting table on which the tablet sheet 51 transported by the transport mechanism 16 is mounted, and an extruding mechanism for pressing the tablet sheet 51 on the mounting table from the side of the tablet container and taking out the tablet. . That is, the top of the mounting table is used as the unpacking position (extraction position). The tablet sheet 51 is sealed in the tablet housing part by providing a sealing sheet using a metal foil made of aluminum or the like on the lower surface of the sheet main body having the tablet housing part 510 for housing the tablet. Furthermore, the tablet sheet 51 has a form in which convex tablet accommodating portions are arranged in two rows at intervals in the width direction on the sheet portion. The plurality of tablet accommodating portions forming each row are arranged along the length direction of the tablet sheet 51.

  The tablet sheet 51 is not limited to the form in which the tablet accommodating portions are arranged in two rows on the sheet portion, but the form in which the tablet accommodating portions are arranged in one row in the length direction of the tablet sheet 51 It is also possible to adopt a form in which the portions are arranged in a plurality of rows of 3 or more at intervals in the width direction.

  Next, with reference to FIG. 4 and FIG. 5, the tablet extraction operation from the tablet sheet and the behavior of the extracted tablet will be described. FIG. 4 is a view showing the internal structure (cross section) of the tablet take-out unit 1, and is a view of the tablet take-out unit 1 as viewed from the right side. FIG. 5 is a diagram showing an internal structure of the tablet supply device 10 as viewed from the rear side of the device.

  As shown in FIG. 4, the tablet taking-out operation is started after the tablet sheet set in the insertion port 203 is conveyed to the tablet unpacking position (tablet taking-out position).

  The tablet sheet is conveyed by a lower roller 39 and an upper roller (not shown) that function as the conveyance mechanism 16. A plurality of lower rollers 39 are provided at intervals along the traveling direction, and can be rotationally driven by a drive source (not shown), and abuts on the lower surface side in the gravity direction of the tablet sheet and proceeds to the tablet sheet 51. It can be transported by applying force to the method.

  Note that the tablet take-out unit 1 is provided with a detection mechanism 17 that can detect the length of the pressed tablet storage part and the position of the pressed tablet storage part. Using the length and the position of the tablet container, it is also possible to calculate the optimum transport distance and control the transport. In other words, the detection mechanism 17 and the transport mechanism 16 (lower roller 39, upper roller) can transport the tablet sheet to the optimal extraction position and perform the extraction operation.

  Next, the tablet extraction operation by the extrusion mechanism will be described. The extrusion mechanism includes an inner pressing body 83 that presses the vicinity of the center of the tablet accommodating portion, and an outer pressing body 84 that is provided so as to surround the inner pressing body 83 and presses a portion outside the vicinity of the center. ing. The inner pressing body 83 and the outer pressing body 84 operate independently to press the tablet accommodating portion of the tablet sheet and take out the tablet from the tablet sheet. Specifically, the extrusion mechanism is controlled so that the outer pressing body 84 presses the tablet accommodating portion before the inner pressing body 83.

  The tip of the inner pressing body 83 is provided so that the area is narrower than the tablet accommodating portion of most tablet sheets 51 that are supposed to be mounted on the tablet extraction unit. Therefore, when the inner pressing body 83 is lowered in order to take out the tablet, the tip reaches to the lower side in the gravity direction from the surface of the tablet housing portion of the tablet sheet, and from the hole opened in the metal foil of the tablet sheet 51 The tip will protrude downward. On the other hand, the tip of the outer pressing body 84 has a larger area than the tablet accommodating portion of most tablet sheets 51 that are supposed to be mounted on the tablet extraction unit. The tip does not protrude from the hole opened in the 51 metal foil. That is, the tablet container 51 of the tablet sheet 51 is first crushed by using the outer pressing body 84 and then the tablet is reliably pushed out by the inner pressing body 83.

  The extrusion mechanism also has a first lifting mechanism that lifts and lowers the outer pressing body 84 and a second lifting mechanism that lifts and lowers the inner pressing body 83. By operating these, the tablet is pushed out by the pressing body. Can do.

  The first elevating mechanism includes a first elevating body 93 to which the outer pressing body 84 is attached, a cam 94 that drives to rotate the first elevating body 93 and urges the first elevating body 93 in the upward direction. And a biasing member (spring).

  The 1st raising / lowering body 93 is a columnar body extended over the front-back direction, and the outer side press body 84 is attached to the front-end part. The cam 94 is a plate-like body designed in consideration of the lifting operation of the outer pressing body 84, and is fixed to a shaft portion that is rotationally driven by a drive mechanism.

  The cam 94 is provided on the upper surface side of the first elevating body 93, is rotationally driven with the rotation of the shaft portion, adjusts the height position by pressing the first elevating body 93, and thereby the outer pressing body 84. The height position of the outer pressing body 84 can be adjusted (the elevating operation of the outer pressing body 84 is performed). The first elevating mechanism can arbitrarily set the timing and displacement amount of the outer pressing body 84 by setting the timing of the cam rotation operation, the shape of the cam, the fixed position of the cam with respect to the shaft portion, and the like.

  The second elevating mechanism includes a second elevating body 98 to which the inner pressing body 83 is attached, a cam 99 that rotates to drive the second elevating body 98 up and down, and biases the second elevating body 98 in the upward direction. And a biasing member (spring).

  The second elevating body 98 is a columnar body extending in the front-rear direction, and an inner pressing body 83 is attached to the front end portion. The cam 99 is provided on the upper surface side of the second elevating body 98 and is rotationally driven with the rotation of the shaft portion, and presses the second elevating body 98 to adjust the height position. The height position can be adjusted (the inner pressing body 83 is moved up and down). The second elevating mechanism can arbitrarily set the elevating operation timing and displacement amount of the inner pressing body 83 by setting the rotation timing of the cam 99, the shape of the cam, the fixed position of the cam with respect to the shaft portion, and the like.

  For this reason, the cam 94 and the cam 99 can operate independently of each other with respect to the first lifting body and the second lifting body, respectively, and the inner pressing body 83 and the outer pressing body 84 can be lifted and lowered independently of each other. it can.

  The timing of the rotational operation of the two cams in the extrusion mechanism can be determined based on a signal from the detection unit of the tablet position detection mechanism. Specifically, the inner pressing body 83 and the outer pressing body 84 can be operated in accordance with the detected position of the tablet accommodating portion.

  By controlling such an extrusion mechanism, the tablet can be taken out from the tablet sheet. And the taken-out tablet is guide | induced to the tablet introduction path 601 through the introduction chute | shoot 24 provided in the lower surface side of the mounting base.

  If it is determined that the tablet has not been taken out even though the tablet has been taken out, the taking out operation is continued (retry). Specifically, if the tablet cannot be detected by the optical sensor 204 provided on the introduction chute 24 even though the removal operation has been performed, it is determined that the tablet has not been removed and the operation proceeds to the retry operation. To do. Further, during the retry operation, the tablet sheet 51 is transported and shifted by the transport means by a predetermined distance from the pressing position on the mounting table 18 before the tablet container is pressed again, and the extrusion mechanism is used in this state. You may press a tablet accommodating part. By performing the retry operation in such a state, it is possible to reliably take out the tablet even if the tablet is not taken out by a single take-out operation.

  Further, the tablet take-out unit 1 is equipped with a changing mechanism for changing the speed at which the tablet accommodating portion of the tablet sheet 51 on the mounting table 18 is pressed, and the pushing speed of the pushing mechanism during the retry operation is changed to be higher than the normal speed. And you may press a tablet storage part.

  Next, how the tablet taken out by the tablet taking-out operation moves will be described with reference to FIG. 6 which is a view of the inside of the tablet supply device 10 seen from the side (right side when viewed from the front). The arrow shown in FIG. 6 has shown the movement path | route of the tablet taken out from the tablet extraction unit 1. FIG.

  The tablets conveyed through the introduction chute 24 are conveyed to the first accumulation hopper 602 via the tablet introduction path 601. In the first accumulation hopper 602, the tablets taken out from the tablet sheet by the plurality of tablet extraction units 1 overlapping in the direction of gravity are accumulated. A plurality of such first accumulation hoppers 602 are provided in a direction crossing the direction of gravity, and the tablets accumulated by such a plurality of first accumulation hoppers 602 are further accumulated in one second accumulation hopper 603. Is done.

  Then, the first delivery mechanism 604 moves the tablets 50 accumulated in the second accumulation hopper 603 to the third accumulation hopper 605 at a predetermined timing. Then, in the third stacking hopper 605, the tablets input from the handmade input unit 102 and the tablets supplied from the tablet supply device 10 are collected, and the second delivery mechanism 606 as one packaged tablet, It is sent out to the main hopper 707 of the packaging unit 701.

  The unpacked tablet sheet from which the tablets have been taken out is further transported toward the rear side of the tablet supply device by the transport mechanism 16, discharged to the discharge path 607, and accumulated in the discharge pocket 608 (discard box). The The discharge pocket 608 is provided with an opening door on the front side of the tablet supply device 10, and the discharged tablet sheet can be easily taken out.

  Next, the internal structure of the packaging unit 701 will be described with reference to FIG. The packaging unit 701 is a unit provided in the packaging device 5.

  The main hopper 707 accumulates the drugs supplied to the powder input unit 103, the tablets supplied to the hand input unit 102, and the tablets supplied by the tablet supply device 10, and these are stored in a packaging sheet (wrapping paper). Used to input

  The roll paper feed mechanism 702 is a mechanism for sending out roll paper (paper in which the wrapping paper is in a roll shape) in which packaging sheets are continuous. The packaging mechanism 703 and the packaging mechanism 704 are mechanisms that heat and weld the packaging sheet. The packaging mechanism 703 can weld the packaging sheet in a direction that intersects the feeding direction of the packaging sheet. The packaging sheet can be welded in a direction along the sheet feeding direction.

  By using such packaging mechanisms 703 and 704 to heat and weld the packaging sheet, one tablet (drug) can be packaged together. The packaging sheets individually packaged in this way are divided by a dividing mechanism 705 to be divided into packaging sheets for each package.

  Further, the printing mechanism 706 can print the date, patient data, and error information on the packaging sheet. In addition, as a packaging sheet, not only the paper which coated the resin material which can be heat-welded on the surface but the transparent film material which can visually recognize the contents can also be used.

  Next, a situation that has conventionally occurred when using such a tablet supply device by a person in charge of dispensing work (hereinafter also referred to as a user) will be described with reference to the drawings.

  FIG. 8A shows an example of a prescription. Since the prescription content of the prescription is different for each patient as described above, the number of tablet sheets to be used, that is, the number of tablet takeout units to be used is different. For example, in the case of the prescription 800, five tablet takeout units are used. However, in the case of the prescription 801, only one tablet take-out unit is used.

  Then, most users put drugs in order from the unit 1 of the tablet taking-out unit in the order described in the prescription. In the example of the prescription 800, the AAA tablet is inserted into the unit 1, the BBB tablet into the unit 2, the CCC tablet into the unit 3, the DDD tablet into the unit 4, and the EEE tablet into the unit 5. Further, in the example of the prescription 801, the BAB tablet is inserted into the unit 1. As a result, most users use the tablet supply device by inserting the tablet sheets so that the operation results increase in order from the unit 1, as in the relationship between the unit and the number of operations shown in FIG. become. The graph of FIG.8 (b) has shown the frequency | count of operation | movement of the units 1-12 of the tablet supply apparatus used for 4 months at a certain pharmacy. As can be seen from this, it can be seen that the unit 1 is used nearly four times as much as the unit 12.

  However, if the position of the tablet taking-out unit that is freely used by the user is determined in this way and only a specific tablet taking-out unit is frequently used, a problem will occur in the tablet taking-out unit that is not used much. Even if this is not the case, a problem will occur in the tablet take-out unit that is used frequently, and maintenance of the tablet supply device will be required at an early stage. In other words, the dispensing operation cannot be performed, and the person in charge of maintenance of the apparatus is called, and the frequency of causing troubles in business becomes high.

  Therefore, in the present embodiment, the operation record of the tablet take-out unit is stored for each tablet take-out unit, and the tablet sheet to be loaded so that the tablet take-out unit is used on average using this operation record. By determining the position of the take-out unit and notifying the user, it is possible to prevent a situation in which a specific tablet take-out unit is frequently used, and to reduce the frequency with which maintenance of the tablet supply device is required. .

(First embodiment)
Hereinafter, as the first embodiment, a mechanism for storing the number of times that the tablet extraction operation is performed as an operation result is stored for each tablet extraction unit, and using this number of operations, the position of the tablet extraction unit to be inserted is determined in detail. explain.

  First, the flow of the tablet extracting operation will be described with reference to the flowchart of FIG. Such control is realized by reading and executing a control program stored in the CPU 11 of the tablet supply device 10.

  In S101, the CPU 11 of the tablet supply device 10 determines whether or not the unpacking operation has been completed because the number of unpacked tablets that have already been unpacked becomes the number of unwrapped designated by the prescription data. Specifically, it is possible to determine whether or not the extraction operation is completed by managing the total number of tablets detected by the optical sensor 204 for each tablet extraction unit 1 in the storage unit as the tablet count data. it can.

  If it is determined that the removal has been completed, it is determined that the take-out operation has been completed, the tablet sheet is discharged to the discharge unit, and the process ends. If the number of unpackings has not been reached, the process proceeds to S102.

  In S <b> 102, the CPU 11 of the tablet supply device 10 conveys the tablet sheet by the conveyance mechanism 16 so as to reach the tablet extraction position. When the taking-out operation is continuously performed, the tablet sheet is conveyed by one row at the interval of the tablet storage unit.

  In S103, the CPU 11 of the tablet supply device 10 causes the push-out mechanism to take out the tablet from the left tablet storage unit. In S104, CPU11 of the tablet supply apparatus 10 increments the count of the operation frequency table which manages the operation frequency of a tablet unit once, and progresses to S105. In the present embodiment, the operation frequency table is stored in the information processing device 300, and the CPU 11 of the tablet supply device 10 counts up the information processing device 300 every time the above-described extraction operation is performed. Is instructing.

  In S105, the CPU 11 of the tablet supply device 10 determines whether one tablet is detected based on whether or not the passage of the tablet is detected (successful removal) by the optical sensor 204 within a predetermined time after the removal operation is performed. If no tablet is detected, the process proceeds to S106, and a retry operation for removing the tablet is performed. Then, as shown in S107, the count of the operation frequency table for managing the operation frequency of the tablet unit is incremented once as the operation frequency during the retry operation, and the process proceeds to S108.

  In S <b> 108, the CPU 11 of the tablet supply device 10 determines whether one tablet has been detected based on whether or not the passage of the tablet has been detected (successful removal) by the optical sensor 204 within a predetermined time after the removal operation. If no tablet is detected, the transport mechanism 16 changes the tablet unpacking position in S109, and the process returns to S106 to perform the retry unpacking operation again.

  If a tablet is detected in S105 and S108, in S110, it is determined whether the unpacking operation has been completed, with the number of unpacked tablets already being unpacked being the number of unwrapping specified in the prescription data. To do. Specifically, it is possible to determine whether or not the extraction operation is completed by managing the total number of tablets detected by the optical sensor 204 for each tablet extraction unit 1 in the storage unit as the tablet count data. it can. If it is determined that the removal operation has been completed, it is determined that the take-out operation has been completed, the tablet sheet is discharged to the discharge unit, and the process ends. If the number of unpacking has not been reached, the process proceeds to S111.

  In S111, the CPU 11 of the tablet supply device 10 causes the push-out mechanism to take out the tablet from the right tablet storage unit. In S112, the CPU 11 of the tablet supply device 10 increments the count of the operation frequency table for managing the operation frequency of the tablet unit once, and proceeds to S113.

  In S113, the CPU 11 of the tablet supply device 10 determines whether one tablet has been detected based on whether or not the passage of the tablet has been detected (successful removal) by the optical sensor 204 within a predetermined time after the removal operation. If a tablet is not detected, the process proceeds to S114, and a retry operation for removing the tablet is performed. Then, as shown in S115, the number of operations in the operation number table for managing the number of operations of the tablet unit is incremented once as the number of operations during the retry operation, and the process proceeds to S116.

  In S116, the CPU 11 of the tablet supply device 10 determines whether one tablet is detected based on whether or not the passage of the tablet is detected (successful removal) by the optical sensor 204 within a predetermined time after the take-out operation is performed. If the tablet is not detected, the unpacking position of the tablet is changed by the transport mechanism 16 in S117, and the process returns to S114 to perform the retry unpacking operation again.

  On the other hand, if it is determined in S113 and S116 that the tablets have been taken out, the process returns to S101, and it is determined whether or not the predetermined number of packages have been removed.

  As described above, every time a tablet extraction operation is performed, the count of the operation count table is incremented, and the number of operations is counted for each tablet extraction unit. Note that by counting not only the normal extraction operation but also the number of times of the retry operation, it is possible to obtain a more accurate number of operations.

  As a storage means for storing such an operation frequency table, a memory in the tablet supply device 10 may be used, but it may be stored in a memory in the information processing device 300.

  An example of the operation count table stored in the memory of the information processing apparatus 300 is shown in FIG. In the operation frequency table, the operation frequency 1302 and the allocation presence / absence 1303 are stored for each number of the tablet extraction unit 1301. In the present embodiment, the number of operations on the left side and the number of operations on the right side are added to obtain the number of operations, but the left side and the right side may be counted separately.

  Next, with reference to the flowcharts of FIGS. 10 to 12, a description will be given of a flow in which the information processing apparatus 300 determines which tablet tablet of the tablet specified by the prescription data is to be input and notifies the user.
