The second detection sensor 52 is supported by a support member (not shown), and the powder mass 91 is in a predetermined direction X on the other side X2 at a predetermined end position (FIG. 5C). The powder mass 91 is arranged at a position where the powder mass 91 can be detected when it reaches the position shown in FIG. Accordingly, the first and second detection sensors 51 and 52 are configured such that when the powder mass 91 arrives at the terminal positions of the one side X1 and the other side X2, the one side X1 terminal position and the other side X2 terminal of the powder mass 91, respectively. A position detection signal can be transmitted to each control unit CONT. Here, the drive mechanism 30a is configured so that the initial position of the powder mass 91 can be detected by an initial position detection switch (not shown). Therefore, the powder mass 91 is moved to the initial position (FIG. The position shown in A) can be arranged. Here, FIG. 5 is a diagram for explaining the movement state of the powder mass 91, FIG. 5 (A) shows the initial state of the powder mass 91, and FIG. FIG. 5 (C) shows a state when the end position on the side X1 has arrived, and FIG. 5 (C) shows a state when the powder mass 91 arrives at the end position on the other side X2 in the predetermined direction X.

  Accordingly, the powder mass driving unit 30 linearly arranges the first to Nth powder masses 91 along the predetermined direction X in the drive mechanism 30a under the instruction of the control unit CONT (FIG. 5). (See (A)), when the drive device 30b moves to the one side X1 end position (see FIG. 5B), the Nth powder mass 91 is moved to the medicine supply position (this example) by the drive mechanism 30a. Then, one side X1 from the upper position of the drug hopper 28) is positioned in the vicinity of the drug supply position, and the direction gradually changes from the Nth powder mass 91 to the first powder mass 91. When the drive device 30b moves to the other side X2 end position (see FIG. 5C), the first powder mass 91 is moved to the medicine supply position by the drive mechanism 30a. On the other side X2 So as to be located in the vicinity of the drug supply position, and can be arranged on the other side X2 end position to gradually diverted from the first powder mass 91 toward the N-th powders mass 91.

  As shown in FIG. 2, the operating means 40 is a first operating means 41 (in this example, a push button that does not turn on unless pressed) that directs the movement of the powder mass 91 in the predetermined direction X one side X1 only during operation. Switch) and second operating means 42 (in this example, a push button switch that does not turn on unless pressed) that instructs the movement of the powder mass 91 in the predetermined direction X to the other side X2 only during operation.

  The first and second push button switches 41 and 42 are connected to the control unit CONT (see FIG. 4), and are turned on only when being operated (pressed here). The movement of the mass 91 is instructed.

  In the medicine packaging apparatus 100 shown in FIG. 1, when the powder is packaged, first, the powder mass 91 is arranged at the initial position (see FIG. 5A). After the position adjustment of the partition plate 15 is performed, the powder is supplied into the V-shaped mass surrounded by the one end plate 13, the partition plate 15, the fixed plate 12, and the movable plate 14, and the surface of the powder becomes uniform. Is done. Next, the movable plate 14 is rotated from the solid line position in FIG. 3B to the chain line position, and the powder in the V-shaped mass falls into each powder mass 91 of the powder storage body 9 below. Thus, the powder is equally divided and fed into each of the 45 powder masses 91 excluding the powder powder mass at the extreme end.

  Next, the powder powder is temporarily retracted from the powder supply position (in this example, the position above the drug hopper 28) located substantially at the center of the shelf board 4 to the predetermined position X one side X1 terminal position. The gears 31 and 32 are rotationally driven by the driving device 30b until the first detection sensor 51 detects the one side X1 end position of the powder mass 91 in the mass driving unit 30, and accordingly, the endless belt 8 is moved to the one side X1. (See FIG. 5B). Thereafter, the endless belt 8 is intermittently driven in the predetermined direction X on the other side X2, and each powder mass 91 is sequentially moved to the powder supply position from the powder mass 91 located on the tip side. Thus, when each powder mass 91 reaches the powder supply position, the open / close lid 10 is operated in the opening direction by the operation of the lid opening / closing mechanism (not shown), thereby opening the bottom of the powder mass 91 and disposing the powder mass 91. The powder inside falls to the drug hopper 28 below.

  On the other hand, in the packaging device 7, the packaging sheet is fed out from the roll body 24 at the same timing as the powder is dropped, and the powder falling from above through the hopper 28 is received by the packaging sheet at a predetermined position and continuously. Packaging is performed. Then, after the powder mass 91 supplied with the powder has moved by the powder mass driving unit 30 until the second end sensor 52 detects the other end X2 end position of the powder mass 91 (see FIG. 5C), It again moves to one side in the predetermined direction X and is returned to the initial position (see FIG. 5A) to prepare for the next packaging operation.

  In the medicine packaging device 100 operating in this way, the operator moves the powder mass 91 in the lower part of the drug mass 91 when, for example, cleaning or maintenance of powder or the like or some trouble processing is performed. .

  FIG. 4 shows a schematic block diagram of a control system of the powder supply device 5 shown in FIG.
