Hereinafter, an embodiment of the present invention will be described based on the attached drawings.
As shown in FIG. 1, the medicine extracting device 1 of this embodiment includes a sheet conveyance path 2 for conveying a PTP sheet 100 which is a medicine sheet, and an medicine drop formed orthogonal to the conveyance direction of the PTP sheet 100. For removing the PTP sheet 100, the pocket pressing portion 3 for pressing the medicine containing pocket portion 100a of the PTP sheet 100 by the pushing member 31, the raising and lowering portion 4 for moving the pushing member 31 up and down, A sheet fixing portion 5 to be fixed, a drug passage 6 through which a drug taken out from the drug containing pocket portion 100a passes, a transport width adjusting portion 7 for controlling the transport width of the sheet transport path 2, and the drug dropping opening And an opening width adjusting portion 8 for adjusting the width of the portion 26 (which is also the pressing width of the sheet fixing portion 5).

  The sheet conveyance path 2 conveys the PTP sheet 100, for example, in the long side direction. The sheet conveyance path 2 can also stop the PTP sheet 100 when the medicine containing pocket portion 100 a to be removed reaches the medicine dropping opening 26. Whether or not the drug containing pocket portion 100a to be removed has arrived on the drug dropping opening 26 is, for example, a process of analyzing a captured image of the PTP sheet 100 from an imaging camera or an output of an optical sensor And so on. The drug-retaining pocket portion 100a which is unremoved has a convex shape, while the drug-retaining pocket portion 100a which has been removed is crushed and becomes substantially flat. Therefore, the unwrapped state is detected by detecting such a difference in shape. It is possible to determine whether or not the PTP sheet 100 is transported when the unpackaged drug storage pocket 100a is detected at the position of the drug dropping opening 26.

The start position and the end position of the movement in the short side direction in the base block are detected using, for example, the light sensor 36.

  The opening width adjusting unit 8 includes a guide interval setting motor 8a. The gears 81a and 81b, the first feed screw 81c and the pulley 81d of the transmission mechanism 81 are rotated by the guide interval setting motor 8a. The rotation of the pulley 81d is transmitted to the pulley 81f shown in FIG. 2 and FIG. 4A by the belt 81e, and when the pulley 81f rotates, the second feed screw 81g rotates. Further, two width adjustment blocks 82 forming the drug dropping opening 26 are disposed apart from each other. Each of the first feed screw 81c and the second feed screw 81g is formed with two screw parts for feeding the width adjustment block 82 in the opposite direction. When the first feed screw 81c and the second feed screw 81g rotate, the width adjusting block 82 approaches or separates from each other, and the sheet fixing portion 5 presses the PTP sheet 100 and the holding width and the drug dropping opening The opening width of the portion 26 is adjusted.

  The elevating unit 4 is provided on a support portion 41 fixed to the base block so as to movably support the push-out member 31 in the vertical direction as shown in FIG. The rack portion 42, a pinion portion 43 provided to mesh with the rack portion 42, and a motor 44 for rotating the pinion portion 43 are provided. By rotating the motor 44 forward and reverse, the push-out member 31 can be moved up and down on the drug dropping opening 26. When the pushing member 31 is positioned at the lowermost position, the lower end of the pressing roller 31a is positioned lower than the drug dropping opening 26 (lower than the sheet surface of the PTP sheet 100). It is desirable to keep

  The sheet fixing portion 5 fixes the PTP sheet 100 when the medicine containing pocket portion 100 a is pressed by the pushing member 31. The sheet fixing portion 5 includes two disc-like members (sheet pressing members) 51 spaced apart so as to straddle the drug dropping opening 26. The disc-like members 51 are the push-out members. The sheet surface of the PTP sheet 100 is pressed while moving with the sheet 31. The support shaft 52a which rotatably supports each disk-shaped member 51 is fixed to the support member 52, as also shown in FIG. 4 (A). The support member 52 is fixed to the base block, and moves in the direction of the short side of the PTP sheet 100 together with the base block by the rotation of the feed screw 34.

  The disc-like member 51 is rotatably supported by the support shaft 52a and is movable in the axial direction (horizontal direction) of the support shaft 52a. The upper side of the circumferential portion of the disc-like member 51 is accommodated in the upper guide recessed groove in the width adjustment block 82, and the lower end side of the circumferential portion is also shown in FIG. 4B. It is located on the lower guide groove 82a in the width adjustment block 82, and is rotationally moved while maintaining such a state. The lower guide groove 82 a is formed at a position on the edge side of the drug dropping opening 26, and the bottom surface is inclined downward toward the drug dropping opening 26. The outer peripheral surface of the disk-shaped member 51 is inclined along the inclination, and when the width adjustment block 82 moves for width adjustment, the disk-shaped member 51 moves along the support shaft 52 a .

  Next, the operation of taking out the medicine will be described using FIG. 5 to FIG.

  As shown in FIG. 5, the PTP sheet 100 is set in the sheet conveyance path 2 so that the long side direction coincides with the conveyance direction. This setting may be performed manually by the user, or the PTP sheet 100 loaded in a cassette (not shown) may be dispensed by the dispensing device and transported to the sheet transport path 2. Further, the holding width when the sheet fixing portion 5 holds the sheet surface of the PTP sheet 100 and the width of the medicine dropping opening 26 are adjusted. This adjustment may be performed by the user operating a switch that turns on or off the guide interval setting motor 8a. Alternatively, the drug take-out device 1 acquires, for example, width information of the short side of the drug containing pocket portion 100a of the PTP sheet 100 from the delivery device or drug database, and gives the pulse to the guide interval setting motor 8a based on the width information. The number and driving time may be determined.

  As shown in FIG. 6, the conveyance width adjustment unit 7 is operated to adjust the conveyance width by moving the guide members 71 provided on both sides of the conveyance surface of the sheet conveyance path 2 closer to or away from each other. . The operation of the guide member 71 may be performed by the user operating a switch that turns the motor 75 on or off. Alternatively, the medicine extracting device 1 acquires width information in the short side direction of the PTP sheet 100 from the dispensing device or medicine database, and determines the number of pulses and driving time given to the motor 75 based on the width information. May be

  As shown in FIG. 7, the PTP sheet 100 moves on the transport surface of the sheet transport path 2 and stops at the position of the drug dropping opening 26. The movement and stop may be performed by the user operating a switch to turn on or off the transport motor 23, or as described above, by unanalyzing the image from the imaging camera or the like. The PTP sheet 100 may be automatically stopped when the drug containing pocket portion 100 a reaches the drug dropping opening 26. Further, for example, the length information and the unpacked number information of the PTP sheet 100 dispensed on the side of the dispensing device are obtained from the drug database and given to the drug extracting device 1, and the drug extracting device 1 is based on the information. It is also possible to determine the number of pulses given to the transport motor 23 and the driving time so that the unremoved drug storage pocket portion 100a to be removed may be positioned on the drug dropping opening 26.

  FIGS. 8 and 9 are views of the medicine taking out apparatus 1 from the downstream side of the transport direction of the PTP sheet 100, and the counter roller 25 is omitted in FIG. Moreover, in FIG. 10, FIG. 11 and FIG. 12, the enlarged view which looked at the chemical | medical agent extraction apparatus 1 from the said conveyance direction downstream side is shown.

  As shown in FIGS. 10 (A) and 10 (B), when the medicine containing pocket portion 100a to be removed reaches the medicine dropping opening 26, the base block moves, and the sheet fixing portion 5 is moved. The disc-shaped member 51 of the present embodiment starts an operation of pressing the sheet surface of the PTP sheet 100. As described above, since the sheet surface of the PTP sheet 100 is pressed by the disk-like member 51, the PTP sheet 100 is stretched over the drug dropping opening 26 to form a state in which the PTP sheet 100 is stretched. It is possible to reliably generate a pressing force against the drug due to the removal of the drug. Furthermore, since the sheet surface of the PTP sheet 100 is sandwiched between the lower end of the peripheral surface of the disk-like member 51 and the lower guide groove 82a, the PTP sheet 100 is firmly fixed.

  As shown in FIGS. 11 (A) and 11 (B), the pressing roller 31a is lowered to press the medicine containing pocket portion 100a. The position where the pressing roller 31a is most lowered is, for example, the position advanced in the advancing direction from the center or the center of the drug containing pocket portion 100a, but the center position for each type of PTP sheet 100 is the PTP sheet 100. The determination may be made by acquiring dimension information from the edge of the to the central position from the drug database. Further, the medicine taking out apparatus 1 can also determine how much the pressing roller 31a has moved from the edge of the PTP sheet 100 based on, for example, the number of driving pulses given to the driving motor 35 and the driving time. . By the lowering operation of the pressing roller 31a, the sheet foil is broken by the medicine in the medicine containing pocket portion 100a and the medicine is taken out, and the taken out medicine falls from the medicine dropping opening 26. The position of the edge of the PTP sheet 100 can be determined, for example, from the number of pulses given to the motor 75 and the driving time, and can also be determined by detecting the position of the guide member 71 by an optical sensor or the like. .

  As shown in FIGS. 12 (A) and 12 (B), if there are a plurality of drug containing pocket portions 100a to be removed, the base block is further moved, and the pressing roller 31a is the second one. The drug containing pocket portion 100a is pressed. Then, when it is detected by the light sensor 36 that the base block has reached the end position, the base block is returned to the start position. If one medicine containing pocket portion 100a is to be removed, the base block is returned to the start position after being pressed against the one piece. In addition, if the pressure roller 31a is kept in the lowered state in such a return operation, the return operation is performed even if the medicine has not completely come out of the medicine containing pocket portion 100a. The drug can be reliably dropped by the

  Here, in the case where the pressure roller 31a is simply moved laterally on the drug dropping opening 26 without being moved up and down by the elevating unit 4, for example, as shown in FIG. If the surface of the storage pocket portion 100a to be pressed by the pressure roller 31a is an inclined surface, even if the height slightly exceeds the radius x of the pressure roller 31a, the drug storage pocket by the pressure roller 31a It is possible to crush the part 100a. On the other hand, as shown in FIG. 13B, if the surface of the drug containing pocket portion 100a which is pressed by the pressing roller 31a is a surface which stands substantially vertically, the height thereof is the radius x of the pressing roller 31a. In the lower range, the pressing roller 31a can crush the medicine containing pocket portion 100a well.

  In this embodiment, since the elevating unit 4 is provided, as shown in FIG. 14, the surface of the drug containing pocket portion 100 a which is pressed by the pressing roller 31 a stands substantially vertically and the height thereof is as described above. Even if the radius of the pressing roller 31a is exceeded, the drug can be reliably removed from the drug containing pocket portion 100a. In particular, by performing the horizontal movement of the push-out member 31 and the downward movement of the push-out member 31 by the elevating unit 4 simultaneously, the pressure roller 31a inclines the medicine containing pocket portion 100a from the position near the upper corner. It will push downward. Such oblique pressing is similar to the operation when a person presses the drug containing pocket portion 100a and takes out the drug, and it is possible to suppress the generation of the aluminum foil sealing the drug containing pocket portion 100a. Further, when the pressing roller 31a is moved obliquely, the angle at the time of the subsequent slanting rise may be made steeper than the angle at the time of the slanting descent. Such control can be performed by making the rising speed faster than the lowering speed of the pushing member 31 by the motor 44.

  The pressing on the drug containing pocket portion 100a is not limited to the above-described oblique pressing, and the horizontal movement of the push-out member 31 is stopped at one end, and the push-out member 31 is vertically lowered by the elevating unit 4 May be Moreover, when performing such vertical descent, the pressing roller 31a is not necessarily required, and the tip of the pushing member 31 may be directly applied to the medicine containing pocket portion 100a. In addition, an elastic material such as rubber may be provided at the tip of the pushing member 31.

  As shown in FIG. 13B and FIG. 14, with respect to the PTP sheet 100 to be processed, the radius x of the pressing roller 31a is equal to or less than the distance y between the edge surfaces of the adjacent medicine containing pocket portions 100a and 100a. If the pressing roller 31a is moved to the edge of the drug containing pocket 100a so as to reliably take out the drug from one drug containing pocket 100a, the pressing roller may be moved to the next drug containing pocket 100a. 31a can be prevented from contacting. Therefore, for example, even if only a part of the plurality of drug containing pocket parts 100a arranged in the direction of the short side is removed and there is an unremoved drug containing pocket part 100a, the medicine containing this unremoved medicine is contained It is possible to prevent sheet breakage or the like from occurring in the pocket portion 100a.

  The drug delivery device 1 of another embodiment is shown in FIG. 15 and FIG. The drug dispensing device 1 includes a sheet transport path 2 for transporting the PTP sheet 100, a drug dropping opening 26 formed orthogonal to the transport direction of the PTP sheet 100, and a drug containing pocket portion of the PTP sheet 100.
