The groove 24 includes one or more inclined surfaces 24a, whereby the shape of the groove 24 forms a shape in which one or more steps are formed. As the drug passes through the inclined surface 24a, the moving speed is increased, so that the distance from another drug to be transferred immediately behind is increased. In this way, the space between the drug and the drug is widened due to the inclined surface 24a formed in the groove 24, so that it is possible to accurately control the discharge of the drug.

It is preferable that the cross-sectional shape of the groove 24 has an English U or V shape so that the medicine can move along the centerline of the groove 24. In addition, when a plurality of inclined surfaces 24a are formed on the plate 22, the angles of the inclined surfaces 24a may be all designed identically or differently from each other as necessary.

The plate 22 vibrating by the vibration unit may be made of a metal material, a nonmetal material, or a metal and a nonmetal material. In particular, the upper surface of the plate 22 in contact with the drug is made of a material of the release drug. Since the moving speed may be changed, the material of the plate 22 may be changed in accordance with the moving speed of the release drug required for design.

For example, when the upper surface of the plate 22 is a metal material, the friction coefficient is small, and thus the drug movement speed is relatively high due to the vibration of the same size, and the upper surface of the plate 22 is a nonmetal material such as plastic. In one case, the friction coefficient is large, and thus the drug movement speed is relatively slow due to the vibration of the same magnitude.

In addition, one plate 22 may be partly made of a metal material, and the other part may be made of a nonmetal material. In this case, along the direction in which the release agent moves, the upstream side (e.g., accommodating part 23 side) where the moving speed is relatively slow is preferably made of a nonmetallic material, and the downstream side where the moving speed is relatively fast ( For example, the groove portion 24 side may use a metal material.

12 is a conceptual diagram illustrating a process for controlling the discharge of the release drug using three sensors. As shown in FIG. 12, according to the first embodiment of the present invention, the discharge of the releasing agent can be controlled using the first and second detection sensors 18a and 18b and the counter sensor 18c. Here, the first detection sensor 18a monitors the release agent passing through the gate members 11a and 11b, and the second detection sensor 18b indicates that the release agent moves toward the end of the plate 22. The counter sensor 18c counts the number of release agents discharged from the end of the plate 22.

12, the release agent moves from left to right as the plate 22 vibrates. The release agent is accommodated in the accommodating portion 23 of the plate 22, and when the drug needs to be discharged, the plate 22 vibrates by the vibrating means 21 as described above, and at the same time, the gate member 11a, 11b) is opened to begin the release of the release agent.

The speed of the release agent moving in will be faster.

The stronger vibration of the plate 22 and the grooves 24 formed on the plate 22 also make the first release agent move faster in the S2 section, so that the first release agent and the next gate member are therefore faster. The gap between the release agents passing through the gap between 11a and 11b can be widened.

When the first release medicament is detected by the second detection sensor 18b to move on the plate 22, the vibration of the vibrating means 21 becomes stronger so that the speed of the release medicament moving on the plate 22 is faster. And the vibration of the vibrating means 21 maintains this state.

Subsequently, the release agent passes through the S3 section and falls at the end of the plate 22. At this time, the counter sensor 18c detects the discharge of the release medicine, that is, the drop, and counts the number of the release medicine at the same time.

In addition, as shown in FIG. 16, the rotation shaft 74a of the motor 74 is preferably configured to be detachable from the rotation shaft 75a of the rotation opening / closing member 75. If the rotation opening and closing member 75 can be attached and detached, the operation during cleaning or maintenance can be easily performed.

The medicine injected into the upper input body 71 is randomly supplied to the receiving portion 23 of the plate 22 whenever the opening 73a is opened by the rotation opening / closing member 75. As described above in the first embodiment, the medicines supplied to the accommodating portion 23 move to the groove portion 24 side of the plate 22 by vibration and are discharged one by one. At this time, the drugs supplied to the receiving unit 23 at random may be aligned in a row by the gate unit to move toward the groove part 24.

Drugs discharged one by one through the groove 24 and the discharge passage 19 are delivered to the hopper 130 by the drug delivery unit 80 and packaged.

The connection passage 83 for delivering the drug discharged to the hopper 130 and the medicine discharged to the hopper 130 and disposed below the swing discharge member 81 are collected in a recovery container (not shown). A recovery passageway 85.

The swing discharge member 81 is provided to be rotated between a predetermined angle by the motor 82 (see FIG. 19). A delivery passage 81a penetrates up and down inside the swing discharge member 81 to adjust the swing angle of the swing discharge member 81 to connect the medicine discharged through the discharge passage 19 to the connection passage 83. Alternatively, it is possible to selectively deliver to the recovery passage (85).

Referring to FIG. 18, where a variation of the medication delivery unit 80 is shown, another pivot discharge member 86 is disclosed. In the embodiment described with reference to FIG. 17, the turning discharge member 81 has a transmission passage 81a formed therein, whereas the turning discharge member 86 shown in FIG. 18 is concave so as to face in the radial direction. It has a pair of accommodating parts 86a.

The chemical | medical agent falling from the plate 22 is temporarily accommodated in the accommodating part 86a. When the predetermined number of drugs falls, the pivot discharge member 86 pivots 180 degrees clockwise or counterclockwise while collecting the medicines contained in the accommodating portion 86a (when rotating clockwise) or the connection passage. Optionally transfer to 83 (when rotating counterclockwise).

The number of drugs falling from the plate 22 can be counted by a sensor installed in the discharge passage 19. As shown in Figs. 13, 21, and 22, the sensor may be an optical sensor including a light emitting portion 19a and a light receiving portion 19b.

In order to smoothly perform the counting by the sensor in the discharge passage 19, the pin member 26 protrudes from the end of the plate 22 so that the drop speed of the falling medicine can be reduced instantaneously. The drug falling from the end of the groove 24 of the plate is caught by the pin member 26 and rounded down to the left or right of the pin member, so that the drop speed can be reduced instantaneously. Thereby, the detection by the sensor installed in the discharge passage 19 can be performed more reliably.

According to the present invention, it is preferable that a plurality of light emitting portions 19a and light receiving portions 19b are arranged in a row. As shown in Figs. 21 and 22, for example, if the sensor includes 10 light emitting portions 19a and light receiving portions 19b, respectively, the two medicines fall from the plate 22 at about the same time. Edo can accurately count the number of drugs.

Referring to FIG. 22, the medicine falling from the plate 22 is caught by the pin member 26 provided at the end of the plate and rounded down to the left or right side of the pin member 26. In the case of falling, one drug each falls on the left and right sides of the pin member 26 due to interference between them.

When two drugs fall in this manner, if only one light emitting unit 19a and one light receiving unit 19b are installed, the drug can be detected, but if two drugs are dropped at the same time, one drug is dropped. It cannot be distinguished.

However, according to the present invention, since the plurality of light emitting portions 19a and the plurality of light receiving portions 19b are provided as described above, for example, the medicine on the left side is the second to fourth light emitting portions 19a and the light receiving portion 19b from the left most. The drop of the drug is detected by the) and the drop of the drug can be detected by the seventh to ninth light emitting unit 19a and the light receiving unit 19b from the left most. At this time, since the fifth and sixth light emitting units 19a and the light receiving unit 19b did not detect the drugs, it can be recognized that the total of two drugs dropped. That is, when the drop of the medicine is detected by the plurality of light emitting units 19a and the light receiving unit 19b, if there are the light emitting unit 19a and the light receiving unit 19b which do not detect the drop in the middle, the two drugs are almost simultaneously. It can be recognized as falling.

On the other hand, the drug discharge device of the present invention may further include a cover (not shown) which is installed to be opened and closed above the plate 22.

In addition, according to the present invention, the plate 22 may be made of a transparent material, and the sensing sensor may be integrally embedded in the inside of the plate 22.

The first plate 63 and the second plate 64 are configured to vibrate by separate vibrating means 21, respectively, as described above, thus vibrating the first plate 63 and the second plate 64. The speeds can be determined differently from each other. For example, the second plate 64 on the side where the medicine is discharged may vibrate faster than the first plate 63 on the side where the medicine is injected.

In addition, one or more protrusions 64b and one or more recesses 64c are formed in the second grooves 64a to prevent the oval or cylindrical drugs from rolling in the grooves, thereby preventing the medicines from agglomerating with each other. can do. According to the present invention, only the protruding portion 64b or the concave portion 64c may be formed in the second groove 64a.

In addition, as described above, the pin member 66 protrudes from the end of the plate 64 so that the falling speed of the falling medicine is instantaneously reduced to more accurately perform the counting of the medicine by the sensor. Since the medicine falling at the end of the second groove 64a of the plate is caught by the pin member 66 and rounded off to the left or right of the pin member, the drop speed can be reduced instantaneously. Thereby, the detection by the sensor installed in the discharge passage 19 can be performed more reliably.
