You need to use your body. Therefore, as in the first conventional example and the second conventional example described above, in the powdered medicine dividing / conveying unit in which the powdered medicine storing units 2 are linearly arranged in a line, the length L2 of the moving passage of the powdered divided mass assembly 3 is At least, the total length L1 of the powder mass division mass assembly 3 must be set to double, which causes a problem that the dimension in the transport direction (lateral direction) becomes long. In addition, as in the third conventional example, there is a case in which the powder medicine divided mass assembly 3 is divided into two parts to suppress the length in the carrying direction, but in such a configuration, the powder medicine divided mass assembly 3 is divided into two parts during operation of the medicine packing machine. Since it is necessary to move the powdered mass division mass assembly up and down, there is a problem that the powdering powder packing operation must be temporarily stopped until this operation is completed. That is, if the number of packages is the same, the time required for the packaging work will be extended by the amount of the stop time, and therefore a measure is desired to improve the work efficiency. In addition, there is also a problem in that a structure in which a lift mechanism is provided and retracted upward is disadvantageous in terms of securing a space in the vertical direction.

The present invention has been made in view of the above circumstances, and does not reduce the storage capacity of the powder medicine storage portion or the work efficiency, and does not increase the vertical dimension, either. The purpose is to shorten the length of the device, reduce the width of the entire device, and achieve miniaturization.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a powder medicine dividing and conveying section and a medicine packing machine according to the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 is a perspective view showing a powdered medicine dividing / conveying unit according to the present invention. The powdered medicine dividing / conveying unit 20 includes a powdered medicine storage unit connecting body 21 and a guide rail 40. Among them, the powdered medicine dividing / conveying unit 20 divides and stores one package of powdered medicine into each powdered medicine storage unit in a medicine packaging machine, conveys it to the powdered medicine packaging position, and sequentially discharges one package of powdered medicine from the powdered medicine storage unit. It is a part configured to do.

This powder medicine storage unit connecting body 21 is shown in FIG. 3 (b).
As shown in FIG. 5, a large number of powder medicine storage portions 25 each having an upper opening 22 for introducing powder medicine and a lower end opening 24 for discharging powder medicine provided with an openable / closable bottom lid 23 are provided in the conveying direction indicated by an arrow 26 in the figure. They are arranged side by side. The powder medicine storage section 25 is
As shown in FIG. 2, the lower portions adjacent to each other in the transport direction are pin-coupled to each other via the connecting member 27 and the pin 28. As a result, a large number of powder medicine storage units 25
The powdered medicine storage portion connecting body 21 formed by connecting the above is long in the transport direction, and is configured such that the adjacent powdered medicine storage portions 25 can be bent around the pin 28 as a rotation axis.

The guide rail 40 is a guide member that slides and moves the above-mentioned powdery medicine storage unit connecting body 21 between the powdery medicine carrying area and the shelter area. The powdered medicine carrying region is a region where the powdered medicine is supplied from the upper opening 22 and stored in the powdered medicine storage unit 25 by maintaining the upper opening 22 upward, and conveyed to the powdered medicine falling position. Therefore, in the illustrated example, the guide rails 40 in the powdered medicine conveying region are horizontally arranged. In addition, the powdered medicine storage area is at the end portion of the connected medicine powder storage portion connecting body 21 that is closest to the evacuation area.
The whole is located in the horizontal part of the guide rail 40 so that 5 can be a powder dropping position. At the powder dropping position, a hopper 50 is installed below the lower end opening 24, and the bottom lid 23 is sequentially opened by a known means (not shown), so that the powder in the powder storage portion 25 falls into the hopper 50. The hopper 50 guides the powdered medicine to a later-described powdered medicine packaging portion.

On the other hand, the evacuation area is formed by connecting the guide powder 40 downward from the above-mentioned powder medicine conveying area and connecting the empty areas to discharge the powder medicine in the powder medicine accommodating section 25 at the powder medicine dropping position to empty the powder medicine accommodating section. This is a region in which the body 21 is sequentially bent downward by approximately 90 degrees, and the upper opening 22 is guided to the retracted position facing the side surface. Such downward bending of the powder medicine storage unit connection body 21 is possible by connecting the lower portions of the adjacent powder medicine storage units 25 to each other with a pin 28. That is, the powdered medicine storage portion 25 guided to the evacuation area along the guide rail 40 rotates about the pin 28 and is bent downward from the adjacent powdered medicine storage portion 25 in the powder medicine transfer area. . It should be noted that the escape area of the guide rail 40 may have such a length that the powder medicine storage portion 25 at the end position farthest from the escape area can reach the powder medicine dropping position and discharge the powder medicine.

The above-mentioned powder medicine storage portion connecting body 21 reciprocates in the carrying direction indicated by an arrow 26 in the drawing, but the movement is carried out by using an appropriate driving means not shown. As the driving means, for example, a reciprocating operation is possible, such as a structure in which a locking portion integrated with a timing belt rotated by a driving motor is removably locked at an appropriate position of the powder medicine storage unit connecting body 21. Any known material may be used.

Then, at the tip of the above-mentioned hopper 50,
As shown in FIG. 3, a powdered medicine packaging part 60 is provided, and in the powdered medicine packaging part 60, the powdered medicine supplied from the hopper 50 is packaged in a predetermined drug-encapsulated package (paper bag) or the like. Has become. As described above, the tablet packaging machine includes a powdered medicine dividing / conveying unit 20 that divides and supplies the powdered medicine for one administration, and a powdered medicine packaging unit that receives and distributes the powdered medicine divided by the powdered medicine dividing and conveying unit 20. And 60.

The guide rail 40 described above is shown in FIG.
As shown in (2), it is divided into two parts at appropriate positions in the horizontal powdered medicine conveying area, and is configured to be able to move up and down in the vertical direction integrally with the evacuation area side. This is because the powder medicine storage unit connection body 21 is placed in the retracted position, and is lifted from the normal connection position by the elevating mechanism, and the powder medicine storage unit connection body 2 is separated from the separated horizontal end.
1 can be easily pulled out and cleaned. As a suitable lifting mechanism 70, for example, as shown in FIG. 4, the rack gear 7 integrated with the guide rail 40 is used.
1 and a pinion gear 72 that meshes with the rack gear 71
And a rail member 73 that supports the guide rail 40 so as to be vertically movable. The elevating mechanism 70 rotates the pinion gear 72 by an electric motor or the like (not shown) to move the guide rail 40 and the powder medicine storage unit connecting body 21 to a normal connection position and a separation position which is raised from the same connection position. In between, it is possible to move up and down along the rail member 73.

The powdered medicine dividing / conveying section 20 having the above-mentioned structure.
In this case, since the vertical evacuation area is provided, the length of the powdered medicine carrying area in the horizontal direction can be minimized. Therefore, the horizontal dimension (horizontal width dimension) of the medicine packing machine can be reduced, and the entire apparatus can be downsized. That is, after the powdered medicine is discharged, the powdered medicine storage unit connecting body 21 is bent from the horizontal direction to the vertical direction to be retracted, so that the space area in the medicine packaging machine is effectively used for the vertical save area. In addition, unlike the conventional structure, the size in the vertical direction is not increased to increase the size. In particular, the guide rail 40 in the evacuation area does not necessarily need to be vertical in the vertical direction, and it is possible to give an appropriate inclination according to the configuration of the medicine packing machine, so there are few restrictions, and in relation to other peripheral constituent members. Also has a high degree of freedom in design. Therefore, the vertical dimension of the medicine packing machine as a whole is not increased, and the position where the powdered medicine is charged into the medicine storage section 25 is lowered, so that the workability at the time of charging the powdered medicine can be improved.
Further, the guide rail 40 is divided to provide an elevating mechanism 70 so that the powder medicine storage unit connecting body 21 can be easily attached and detached from the guide rail 40. Since it can be easily divided into the parts 25, the cleaning work inside the powder medicine storage part 25 becomes extremely easy.

[0024]

According to the above-mentioned powdery medicine divided conveying section of the present invention and the medicine packing machine having the powdered medicine divided conveying section as a constituent element, the powdered medicine storing section is pin-coupled to form the powdered medicine storing section connecting body, and the powdered medicine storing section is formed. Since the powdered medicine storage section after discharge is bent downward from the horizontal powdered medicine transfer area along the guide rail to be guided to the evacuation area, it is possible to reduce the volume of the powdered medicine storage section in the transfer direction. Also, the size in the vertical direction can be suppressed to be small, and the size can be reduced. Therefore, the overall height of the medicine packing machine is reduced, so that the workability at the time of introducing the powdered medicine is increased, and the downsizing of the whole medicine packing machine can reduce the installation space. Further, since the powder medicine storage portion can be easily attached and detached and disassembled, the cleaning operation inside the powder medicine storage portion can be facilitated, which is excellent in hygiene.
