Next, according to the present invention, an embodiment of a medicine packaging apparatus provided with a recess forming device will be described. The drug packaging device 1 of the present embodiment is a device that forms a drug package P by automatically packaging the drug M using the packaging sheet 3 and the lid sheet 4.

As shown in FIG. 1, the medicine packaging apparatus 1 includes a packaging sheet holding unit 11, a packaging sheet supply unit 12, a recess forming unit 13, a drug supply unit 14, a drug feeding unit 15, a lid sheet holding unit 16, a lid. A sheet supply unit 17, a lid sheet bonding unit 18, a cutting unit 19, and a printing unit 20 are provided. Each unit is controlled by the control unit 5.

The packaging sheet holding unit 11 holds a flat packaging sheet (container film) 3. The packaging sheet 3 is a resin sheet. As the packaging sheet 3 of the present embodiment, for example, a thermoplastic resin sheet is used. The packaging sheet 3 has a long band shape, and is held in a wrapping roll-like body 3 a so as to be drawable by the packaging sheet holding unit 11. The dimension in the width direction of the packaging sheet 3 is a dimension that allows one recess 31 to be formed. The flat packaging sheet 3 is not limited to a long belt shape, but is a rectangular shape in plan view (short), and is configured such that a plurality of packaging sheets 3 are stacked on the packaging sheet holding portion 11. You can also Moreover, the packaging sheet 3 of this embodiment is transparent. For this reason, it is easy to visually recognize the medicine M stored in the recess 31 in the state after packaging. In the present embodiment, a transparent packaging sheet 3 is used, but the packaging sheet 3 is not necessarily transparent. The packaging sheet 3 may be translucent or opaque, for example.

In this embodiment, since the flat packaging sheet 3 can be used, the packaging sheet 3 in a rolled state can be held by the packaging sheet holding unit 11. Further, the packaging sheet 3 having a rectangular shape in plan view can be configured to be stacked and held on the packaging sheet holding unit 11. That is, the packaging sheet holding part 11 can hold the packaging sheet 3 in an amount sufficient to form a large number of medicine packaging bodies P at a time. For this reason, it is not necessary to set the trays having the storage recesses one by one as in the prior art. For this reason, the operator of the medicine packaging apparatus is freed from complicated work. The “flat” includes a form in which irregularities and patterns that do not hinder the formation of the concave portion 31 by the concave portion forming portion 13 described later are formed.

The packaging sheet supply unit 12 takes out the packaging sheet 3 from the packaging sheet holding unit 11 and supplies it in the longitudinal direction. The packaging sheet 3 is supplied while the tension is adjusted by a plurality of rollers 121... 121 as shown. Since a driving force is transmitted to some rollers (not shown) provided immediately upstream of the below-described cutting portion 19, the packaging sheet 3 is pulled. For this reason, the packaging sheet 3 is taken out from the packaging sheet holding unit 11. The supply of the packaging sheet 3 is stopped when the recess 31 is formed in the packaging sheet 3 by a molding die 133 described later. For this reason, the supply is made intermittently. Since the packaging sheet supply unit 12 can automatically form the packaging sheet 3 that is supplied and then the medicine M can be charged, the packaging sheet can be easily packaged. The means for taking out the packaging sheet 3 is not limited to a roller. As a means for taking out the packaging sheet 3, for example, a means for sandwiching and pulling the packaging sheet 3 may be employed. Further, as this means, various means such as an arm and a rubber plate can be adopted. In particular, when the packaging sheet 3 has a rectangular shape in plan view, the packaging sheet supply unit 12 is configured so that the packaging sheet 3 can be taken out from the packaging sheet holding unit 11 one by one.

The recess forming part 13 constitutes a part of the recess forming apparatus X and forms a plurality of recesses 31... 31 at predetermined intervals in the longitudinal direction on the packaging sheet 3 supplied by the packaging sheet supply part 12. To do. The formed recesses 31 can contain the medicine M. The recess forming part 13 includes a hot plate 131, a receiving part 132, and a molding die 133. In the present embodiment, a plurality of molding dies 133... 133 having at least different shapes of the female dies 133 a are provided so that the concave portions 31 having different capacities can be formed by the respective molding dies 133. Details of the recess forming device X will be described later.

The hot plate 131 and the receiving portion 132 are opposed to each other with the conveyed packaging sheet 3 interposed therebetween. Each surface where the hot plate 131 and the receiving portion 132 face each other is a flat surface. With respect to the packaging sheet 3, the hot plate 131 is positioned below and the receiving portion 132 is positioned above. The arrangement of the hot plate 131 and the receiving part 132 with respect to the packaging sheet 3 may be reversed. The heat plate 131 has a built-in heater. The receiving part 132 is made of resin. The receiving part 132 of this embodiment is made of rubber.

The drive source of the hot plate 131 and the receiving portion 132 may be any as long as the hot plate 131 and the receiving portion 132 can be moved toward and away from the packaging sheet 3. The drive source of the hot plate 131 and the receiving part 132 may be, for example, an air cylinder or a hydraulic cylinder. In a state where the heater is energized and the hot plate 131 is heated, the hot plate 131 and the receiving part 132 approach so as to sandwich the packaging sheet 3, whereby the packaging sheet 3 can be softened.

The hot plate 131 and the receiving portion 132 are formed to have a size of two packages (two concave portions 31) in the longitudinal direction. On the other hand, the packaging sheet 3 moves intermittently so that the concave portion 31 is formed for every single package (one concave portion 31) by the molding die 133. With this intermittent movement, the packaging sheet 3 is heated twice and then supplied to the mold 133. For this reason, since the first heating is “preliminary heating” and the second heating is “main heating”, the packaging sheet 3 can be sufficiently softened due to the formation of the recess 31. The hot plate 131 and the receiving part 132 are not necessarily formed to have a size of two packages (two concave parts 31) in the longitudinal direction. If the packaging sheet 3 is sufficiently softened by one heating, the hot plate 131 and the receiving portion 132 may be formed in a size of one package (one recess 31) in the longitudinal direction. If the packaging sheet 3 is not sufficiently softened even by two heatings, the hot plate 131 and the receiving portion 132 may be formed in a size of three packages (three concave portions 31) or more in the longitudinal direction. .

In the present embodiment, the female mold 133a, the male mold 133b, and the pressing plate 133c are driven by an electric motor so that the packaging sheet 3 can be approached and separated. The drive source for driving the female mold 133a, the male mold 133b, and the presser plate 133c is not limited to the electric motor. The driving source of the female mold 133a, the male mold 133b, and the presser plate 133c may be any as long as the female mold 133a, the male mold 133b, and the presser plate 133c can be moved toward and away from the packaging sheet 3. The drive source of the female mold 133a, the male mold 133b, and the presser plate 133c may be, for example, an air cylinder or a hydraulic cylinder.

The male mold 133b and the holding plate 133c approach the female mold 133a so as to sandwich the packaging sheet 3 softened by the hot plate 131. While the packaging sheet 3 is sandwiched between the female mold 133a and the presser plate 133c, air is sucked from the plurality of suction holes, whereby a recess 31 that is recessed downward is formed in the packaging sheet 3. In this state, the concave part 31 having a desired shape is reliably formed by further fitting the male mold 133b to the female mold 133a. The male mold 133b is not necessarily provided. The male mold 133b may be omitted if the concave portion 31 having a desired shape can be formed by sucking air from the plurality of suction holes of the female mold 133a.

Note that one set of the molding die 133 of the present embodiment is provided, and is configured to form one recess 31 at a time (one cycle of vertical movement of the female die 133a and the male die 133b). In addition, by arranging a plurality of sets of molding dies 133 in parallel along the longitudinal direction of the packaging sheet 3 or in the width direction of the packaging sheet 3 (front and back direction in FIG. 1), a plurality of recesses 31. 31 can also be formed.

The drug supply unit 14 temporarily stores the drug M. Then, the medicine supply unit 14 supplies the medicine M to the medicine input unit 15 according to prescription data that is data including information on prescription (for example, for each dose). Thereby, the medicine M is supplied to the concave portion 31 formed in the packaging sheet 3 by the concave portion forming portion 13. The drug supply unit 14 includes a storage unit 141 that temporarily stores the drug M.
