Hereinafter, an embodiment of a general drug discharging apparatus to which the present invention can be applied will be described in detail with reference to the drawings prior to the description of the present invention. However, the general drug discharging device is only one embodiment applied to describe the present invention, and it is revealed that the present invention is not limited to the general drug discharging device.

In the present invention, the release agent is a drug having an asymmetrical shape that is not standardized, such as a semi-circular or semi-elliptical tablet that is cut in half, such as a circular or elliptical tablet, and refers to a drug that is difficult to automatically discharge using a conventional cassette device. do. In addition, in the present invention, the drug, as well as the above-mentioned release agent, has a tablet shape of an intact tablet, but requires special handling, such as drugs, so that the existing cassette device cannot be used or the frequency of use is low, so the cassette device is used. It should be considered to include all ineffective drugs.

The drug discharging device to which the present invention can be applied is a device capable of accurately disposing and discharging even a fixed drug, such as a tablet or capsule, as well as a non-formally shaped drug. In order to discharge the medicines exactly one by one, it is necessary to arrange the medicines which are collectively all at once at regular intervals. If the drugs are arranged in too close proximity, there is a fear that one or more drugs may be discharged at once by inertia.

1 to 3, the drug discharging device D to which the present invention can be applied is a frame 10, and is mounted on the frame 10 to move the drugs while separating the drugs from each other in a line A space arrangement unit 20 to be arranged, and a medicine supply unit 30 arranged to be arranged on the upstream side of the space arrangement unit 20 on the frame 10 to supply the medicines arranged in a line to the space arrangement unit 20 and , Further comprising a drug delivery unit 40 for delivering the drug is discharged one by one through the separation unit 20 to the hopper 130 side.

The separation arrangement unit 20 includes vibration generating means 21 for generating vibration and a plate 22 attached to the vibration generating means 21 and vibrating together. As the vibration generating means 21, if the plate 22 can be vibrated in a linear direction, any of the conventionally used components can be used, and thus detailed description thereof will be omitted.

The plate 22 vibrates by the vibration generating means 21 to minutely move the drugs placed on the upper surface. The plate 22 includes a groove 23 that moves the medicine to the discharge passage 42 of the medicine delivery unit 40.

The plate 22 is installed in a state slightly inclined toward the side where the discharge passage 42 is attached, and as the plate 22 vibrates by the spacing arrangement unit, the drugs on the plate 22 gradually discharge the passage 42 Can be moved toward.

The groove portion 23 includes one or more inclined surfaces 24, and thus the bottom surface of the groove portion 23 forms a shape in which one or more steps are formed. As the drug passes through the inclined surface 24, the speed of movement increases, so that the distance from another drug transferred from the back may be further increased. Due to the inclined surface 24 formed in the groove portion 23, the gap between the drug to be discharged and the drug is widened, so that the drug can be accurately controlled.

It is preferable that the cross-sectional shape of the groove portion 23 has a U- or V-shaped shape in English so that the drug can move along the center line of the groove portion 23. In addition, when two or more inclined surfaces 24 are formed on the plate 22, the angles of the inclined surfaces 24 may be all the same or different from each other, if necessary.

The plate 22 vibrated by the separation arrangement unit may be made of a metal material, a non-metal material, or a metal and a non-metal material. Particularly, the release agent depends on the material of the upper surface of the plate 22 in contact with the drug. Since the moving speed of can be changed, the material of the plate 22 may be changed in accordance with the moving speed of the release agent required during design.

In the above description, the separation arrangement unit that arranges the medicines in a row by vibration is described as an example, but if a plurality of medicines can be arranged in a row in a spaced apart from each other, means other than vibration can be used.

As the medicine supply unit 30, a cylindrical feeder mounted on the frame 10 and helically moving the medicine by vibration may be used. The release agents supplied by being poured into the receiving part 31 of the drug supply unit 30 all at once are arranged in a line along the spiral movement path 32 extending from the bottom of the receiving part 31 to the outside of the receiving part 31 Go to. Accordingly, the release agent moving in line along the helical movement path 32 in the cylindrical feeder as the medicine supply unit 30 can be transferred from the cylindrical feeder onto the plate 22, that is, dropped, and the plate 22 continues. ).

One or more cutting grooves 33 may be formed in the spiral movement path 32, and the cutting grooves 33 are provided with the cutting grooves 33 when two drugs move side by side along the spiral movement path 32. As it passes, one drug is dropped to the receiving portion 31 to return. To this end, the cutting groove 33 may be formed at the inner edge of the spiral movement path 32.

The release agent moved to the end of the plate 22 may be delivered to the outside through the drug delivery unit 40. The drug delivery unit 40 includes a discharge passage 42 in which the detection means 41 for detecting the number of medicines to be discharged is mounted, and when the number of medicines is correct according to a result detected by the detection means 41 A packaging passage (43; see FIG. 4) for delivering the discharged drug toward the packaging device 150, and when the number of drugs is not correct according to the result detected by the detection means 41, the discharged drug is collected. And a recovery passageway 44 (see FIG. 4) for delivery to the 45 side.

The detection means installed in the discharge passage 42 so as to detect the number of drugs falling from the plate 22 may be, for example, an optical sensor including a light emitting portion and a light receiving portion.

Meanwhile, one or more sensors (not shown) may be arranged along the plate 22 to detect the location of the drug moving on the plate 22. For example, when a sensor is installed at the distal end of the drug supply unit 30 of the plate 22, the instant immediately after the drug is supplied from the drug supply unit 30 to the plate 22 can be detected, and the plate ( When the sensor is installed at the distal end of the drug delivery unit 40 of 22), the moment just before the drug is supplied from the plate 22 to the drug delivery unit 40 can be detected. In addition, sensors are installed at various other positions on the plate to detect the movement state of the drug.

The sensor may be integrally installed in the plate 22 or may be installed outside the plate 22.

The opening / closing member 46 is pivotably installed at an angle by the opening / closing motor 48, and the staying member 47 is pivotably installed at an angle also by the staying motor 49.

In FIG. 4, the clock is rotated counterclockwise so that the retention member 47 is opened, while supplying the retained drug downward, while the opening and closing member 46 opens the packaging passage 43 and closes the recovery passage 44. The state of turning in the direction is shown by the solid line.

As shown by the dotted line in FIG. 4, when the retention member 47 is turned clockwise to close the discharge passage 42, the medicament may remain on the retention member 47. In addition, as shown by a dotted line in FIG. 4, when the opening / closing member 46 is turned counterclockwise, the pavement passage 43 may be closed and the recovery passage 44 may be opened.

A method for discharging a drug by the drug delivery unit 40 of the drug discharging device D to which the present invention can be applied is as follows.

First, the medicine that has moved to the medicine delivery unit 40 through the plate 22 of the medicine supply unit 30 and the separation arrangement unit 20 passes through the detection means 41 installed in the discharge passage 42. The number of drops is detected. At this time, since the retention member 47 installed in the discharge passage 42 is turned to a position capable of closing the discharge passage 42, all the falling drugs stay on the retention member 47.

If the number of drugs dropped on the staying member 47 matches the preset number, that is, the number to be packaged in one medicament, the opening / closing member 46 opens the packaging passage 43 and opens the recovery passage 44. Turn to a closed position. Then, as the retention member 47 rotates and the discharge passage 42 is opened, the drugs temporarily retained by the retention member 47 drop down and are supplied toward the packaging passage 43.

The medicine supplied to the packaging passage 43 may be supplied to the packaging device 150 through the hopper 130 of the automatic drug packaging machine and packaged.

On the other hand, if the number of drugs dropped on the retention member 47 does not match the preset number, that is, the number to be packaged in one medicament, the opening / closing member 46 opens the recovery passage 44 and The pavement passage 43 is turned to a position where it can be closed. Then, as the retention member 47 rotates and the discharge passage 42 is opened, the drugs temporarily retained by the retention member 47 drop down and are supplied toward the recovery passage 44.

The medicine supplied toward the recovery passage 44 is supplied to the recovery container 45, and the medicine recovered in the recovery container 45 can be reused later.

In other words, when the number of drugs collected and retained on the retention member 47 is less than the number to be packaged, it is waited for the drugs to be additionally moved and stays as unintended situations in which two or more drugs are delivered at once When the number of drugs collected is greater than the number to be packaged, the collected drugs may be delivered to the recovery passage 44.
