Under the locking plate 13, the mounting plate 14 is mounted so as to protrude in the horizontal direction. Mounting pins 15 are fixed to both sides of the lower surface of the mounting plate 14. Ribs 16 are formed on the inner surface of the main body 7. As shown in FIG. 10, the rib 16 supports the inner hopper 6 and forms an air passage between the inner hopper 6 and the outer hopper 5. The rib 16 has an air flow from the chemical supply port 6a of the inner hopper 6 toward the duct 9 and the duct 9 from the chemical collecting port 5a of the outer hopper 5. A cutout portion 16a is formed so as to obtain an air flow toward the. Therefore, the rib 16 prevents suction of the wrapping paper by making sufficient air flow from the chemical | medical agent collection port 5a of the outer hopper 5 toward the duct part 9 as needed.

The chemical | medical agent collection part 8 is formed in narrow width | variety and horizontally so that the wrapping paper A folded into two may be conveyed smoothly toward the inclination downward, and the chemical | medical agent collection port 5a conveys the wrapping paper A. It is inclined upward toward the direction upstream. The chemical | medical agent collection part 8 spreads in width direction toward the chemical | medical agent collection port 5a slightly, and the chemical | medical agent collection port 5a is opened and closed by the opening / closing door 17. As shown in FIG. The opening / closing door 17 is rotatably installed around the support shaft 17a, and pressurizes the pressurized water portion 17b protruding from the intermediate portion, thereby resisting the bias force of the spring 17c. The collecting port 5a opens.

The inner hopper 6 has a funnel shape, and the upper opening portion protrudes outward so that the inner hopper 6 can be mounted on the upper opening edge portion of the outer hopper 5. On the outer surface of the upper opening of the inner hopper 6, a locking part 18, in which the locking piece 11 and the locking jaw 13a of the locking plate 13 is attached and detached, Each is formed.

The hopper 3 is mounted to the fixed wall 20 of the apparatus main body 19 via the support member 21 in a state where the inner hopper 6 is mounted in the outer hopper 5.

The support member 21 is a metal plate bent at approximately right angles, and one end piece is perforated with an opening 22 having a circular cross section, and is bent at approximately right angles in the vicinity thereof to pressurized water pieces 23. ) Is formed. On the pressurized water piece 23, a disc 24 made of synthetic resin material is rotatably mounted. On the other hand, the other end piece of the support member 21 is formed with a hopper support portion 25 by bending in the horizontal direction. The hopper support part 25 is formed with a guide hole 26 through which the mounting pin 15 of the outer hopper 5 is inserted, and the mounting plate 14 is mounted. In the support member 21, the guide shaft 27 is inserted into the through hole 26 formed in the vicinity of the opening 22. An elastic member such as rubber is attached to the guide shaft 27. And the support member 21 is tensioned by the spring 29 which caught the engaging piece 28 of the fixed wall 20. As shown in FIG.

On the fixed wall 20 of the apparatus main body 19, as shown in FIG. 3, the slit 30 through which the said support member 21 is inserted is formed. The mounting member 31 is attached to the fixed wall 20 adjacent to the slit 30, and the motor 32 is fixed thereto. The eccentric cam 33 is integrated with the rotating shaft of the motor 32, and the support member 21 is oscillated by pressing the disc 24 provided in the pressurized water piece 23. As shown in FIG. In addition, a communication hole 34 (see FIG. 10) is formed on the fixed wall 20 on the opposite side to the mounting member 31 with the slit 30 interposed therebetween. The tubular duct member 35 having the branch portion 35a is inserted. The duct member 35 penetrates through the communication hole 34 of the fixed wall 20 and the opening 22 of the support member 21, and is fixed to the fixed wall 20, and the suction pipe 36 (see FIG. 8). ) In this way, when a suction device (not shown) is driven, it is possible to suck the residual chemical in the hopper 3 through the suction pipe 36 and the duct member 35.

And the ring 37a-37e is attached to the duct member 35 as shown in FIG. The ring 37a is screwed to the fixed wall 20, and by changing the screw fastening position to the duct member 35, so that the position of the axial center direction of the duct member 35 with respect to the fixed wall 20 can be adjusted. It is. The rings 37b and 37c are screwed to both sides of one end of the support member 21. The rings 37d and 37e are disposed on both sides of the rings 37b and 37c and screwed to the duct member 35. And the support member 21 with respect to the fixed wall 20, and the hopper 3 mounted to this support member 21 by changing the position of the axial center direction of the ring 37d, 37e with respect to the duct member 35 is carried out. The position of can be adjusted.

A connecting member 38 is attached to the flange portion 35a of the duct member 35, and is positioned on the side opposite to the duct member 35 with the fixing wall 20 therebetween (FIGS. 8 to FIG. 10). The connecting member 38 is composed of a pair of holding pieces 39 made of a synthetic resin material. Each holding piece 39 is free to rotate around the support shaft 39a, respectively. Magnets 40a and 40b are integrated at both ends of each retaining piece 39, and the lower end portion is sucked and abuts the standby position (shown by the dashed-dotted line in FIG. 5), and the upper end portion is sucked. The holding positions (shown by the solid lines in Fig. 5) that abut each can be positioned. In the standby position, protrusions 39b (see FIG. 6A) are formed to protrude inward from a portion of both lower end portions contacted by suction. In the holding position, the duct portion 9 of the hopper 3 is held by both holding pieces 39.

Next, the assembly method of the hopper 3 etc. of the said structure is demonstrated.

First, the inner hopper 6 is assembled into the outer hopper 5. At this time, the locking piece 11 of the outer hopper 5 and the locking jaw 13a of the locking plate 13 are respectively caught by the locking portion 18 of the inner hopper 6, thereby preventing the dropping or shifting of the position. . Then, the rib 16 formed on the inner surface of the outer hopper 5 abuts on the outer surface of the inner hopper 6, and an air flow path is formed. That is, the chemical | medical agent collection ports 5a of the inner hopper 6 and the outer hopper 5 communicate with the duct part 9 via the notch 16a formed in the rib 16, respectively.

On the other hand, in the communication hole 34 formed in the fixed wall 20 of the apparatus main body 19, the duct member 35 which inserted the holding piece 39 freely in advance from the mounting side of the hopper 3 is inserted. Through. And the position of the duct member 35, ie, the holding piece 39, is adjusted by connecting the duct member 35 to the suction pipe 36 and changing the fixed position of the ring 37a. In addition, the support member 21 is inserted into the slit 30 of the fixed wall 20, and the duct member 35 is allowed to pass through the opening 22.

Thereafter, the hopper 3 is attached to the support member 21 from above. At this time, the position of the support member 21 with respect to the fixed wall 20 is adjusted by changing the position of the rings 37b-37e which guide both sides of the one end piece of the support member 21. In the position adjustment of the support member 21, the center of the chemical | medical agent collection port 5a of the hopper 3 and the center of the conveyance path | route of the wrapping paper A are made to correspond. Thereby, it becomes possible to perform the supply of the chemical | medical agent to the wrapping paper A, and the conveyance of the wrapping paper A smoothly. Then, the holding piece 39 attached to the duct member 35 is placed in the standby position shown in Fig. 6A. When the mounting pin 15 is inserted into the guide hole 26 to position the hopper 3 with respect to the support member 21, the duct portion 9 of the hopper 3 is first shown in FIG. 6B. Similarly, since the projection part of the holding piece 39 is pushed down, the lower end part reliably falls off against the suction force of the magnet 40b. Thereby, as shown in FIG. 6C, both holding pieces 39 rotate about the support shaft 39a at the same time, and an upper end part approaches evenly. As compared with the suction force at the lower end, the suction force at the upper end is increased, and the holding piece 39 smoothly rotates to the holding position shown in Fig. 6D. As a result, it becomes possible to hold | maintain the holding piece in close contact with the duct part 9, and to prevent air leakage. And the duct part 9 is guided suitably.

On the other hand, in the case where the hopper 3 is taken out, the locking plate 13 is rotated to release the locking step 13a from the locking part 18, and from the state shown in FIG. 6E, the supporting member ( 21) Lift the hopper 3 upwards. In this case, as shown to FIG. 6F, the upper end part of the holding piece 39 falls by the duct part 9 in reverse from the said mounting time. Since the duct portion 9 abuts on the retaining piece 39 evenly, as shown in Figs. 6G to 6H, the retaining piece 39 can be reliably rotated to a substantially U-shaped standby position.

In this way, the hopper 3 is moved up and down by the hopper 3 and the connecting member 38 of the above-described configuration, without the drug collection unit 8 interfering with the wrapping paper A folded in two upwards. I can put on and take off it.

Next, the packaging operation using the hopper 3 having the above configuration and the cleaning operation of the chemicals remaining in the hopper 3 will be described.

In the packaging operation, one packet of medicine is supplied from the tablet supply unit 1 or the powder supply unit 2 based on the prescription data. The supplied medicine is collected in one place by the hopper 3. At this time, the medicine is once received by the inner hopper 6, and then supplied to the packaging device 4 through the medicine collection unit 8 of the outer hopper (5). Therefore, when accommodated in the wrapping paper A, it becomes difficult to scatter around. In the packaging device 4, as in the prior art, the sheet is folded around two long strip-shaped wrapping papers A, heat-welded at predetermined intervals in the longitudinal direction, and thermally welded to the remaining upper opening after the medicine is received. do. The wrapping paper A is positioned along the outer surface of the chemical | medical agent collection part 8 of the outer hopper 5 formed in narrow nozzle shape. Therefore, even if the chemical | medical agent scattered in the wrapping paper A, it does not leak out.

In this way, the packaging operation of the medicine is continued. In the case of changing the type of the medicine to be supplied, the suction device is driven to remove the medicine remaining in the hopper 3. In this cleaning operation, the opening / closing door 17 is driven to open the chemical | medical agent collection opening 5a by predetermined dimension (it may be full open). As a result, air flow can be formed not only on the side of the drug supply port 6a but also on the side of the chemical | medical agent collection port 5a, and it becomes possible to remove the chemical | medical agent remaining appropriately. Then, by driving the motor 32 to rotate the eccentric cam 33, the hopper 3 swings through the support member 21, and vibrates. Thereby, the chemical | medical agent adhering to the inner surface of the hopper 3 etc. fall easily, and also the removal of a residual chemical becomes easy. In this case, since the hopper 3 swings around the axial center of the duct part 9, trouble such as detachment of the connecting portion does not occur.

Then, if necessary, the hopper 3 is removed from the support member 21 of the apparatus main body 19, and is disassembled and cleaned by the external hopper 5 and the internal hopper 6. Since the duct part 9 is integrally provided in the outer hopper 5, a structure can be cleaned simply and easily.

In the above embodiment, the residual chemicals are cleaned while the upper opening of the hopper 3 is opened. As illustrated in FIG. 11, the upper opening of the hopper 3 is opened and closed by reciprocating in the horizontal direction. The cover member 50 may be provided. In this case, the cover member is partially formed with cutouts 51, so that the air flow can be ensured even when the cover member is closed during cleaning. This makes it possible to form a high-speed air flow as compared with the case where it is fully open, and furthermore, it is possible to appropriately remove the residual chemical. In addition, a motor 52 having a screw screw or the like may be used for driving the cover member.

As apparent from the above description, according to the present invention, since a duct communicating with the suction device is formed in the hopper, the drug remaining in the hopper can be easily removed without the human hand by simply driving the suction device. Can be.
