Description

The present invention relates to a medicine feeder that automatically feeds granular solid medicines such as tablets and ampoules in order to automate dispensing in hospitals, pharmacies, etc. More specifically, the present invention relates to a medicine feeder that automatically supplies a large number of medicines of the same shape. The present invention relates to a drug feeder that randomly stores drugs and aligns the drugs with a rotating body to deliver the drugs one by one, and more specifically, to an improvement in the drug storage capacity of a rotating container.

As a drug feeder that transports tablets, etc. (drugs) of the same shape while aligning them in a row, it has an outer ring-shaped rotating body that can rotate around a vertical line and an axis around an inclined line that is inclined from the vertical. a tilting rotor that is rotatably mounted inside the ring-shaped rotor and closes the hollow of the ring-shaped rotor; A medicine feeder provided with a regulating member that aligns the scattered solid medicine when the annular rotating body rotates has been put into practical use (see, for example, Patent Document 1).

Of these, portions that are useful for understanding the present invention will be specifically described with reference to the drawings (see FIGS. 9 to 13). 9A and 9B show substantially the entirety of the drug feeder 10, with FIG. 9A being a plan view and FIG. 9B being a longitudinal front view. 10(a) is a plan view of the uppermost link mechanism 73 and the upper layer of the peripheral wall 11, and FIG. 60, 71 and 72 are also removed from the plan view. 11A is a front view, a right side view, and a right side view of the sorting member 60, and FIG. 11B is a developed view of the main part of the feeder, showing the peripheral wall 11 and the rotating container 20+30. shows a vertical cross section, and the rotary drive mechanism 50 and the rotary transmission members 42 and 43 show the appearance.

The drug feeder 10 is of a double-rotation type, and has a peripheral wall 11 which is positioned at the top of the housing and has a hollow central portion hollowed out in a circular shape, and the upper end portion of which is loosely fitted in the hollow. An annular rotating body 20 installed in a closed state or installed directly under the hollow of the peripheral wall 11, an inclined rotating body 30 installed in the hollow of this annular rotating body 20, and an inclined rotating body 30 inside this and the annular rotating body 20 on the outer side thereof so as to be axially rotatable, a rotary drive mechanism 50 responsible for driving their rotation, and a sorting member 60 and a regulating mechanism provided on the upper side of the peripheral wall 11 70.

Moreover, the bearing mechanism 40 keeps the ring-shaped rotating body 20 in a state capable of rotating about a vertical line, and the inclined rotating body 30 kept in a state capable of rotating about an inclined line inclined from the vertical. A slight gap is maintained between the inner inclined rotor 30 and the outer annular rotor 20 to block the hollow of the annular rotor 20, while the medicine does not pass but rotation is permitted. The rotary container 20+30 of the double-rotation type medicine feeder is constituted by rotating the inclined rotor 30 and sorting the medicine by the sorting member 60 to lift the medicine from above the peripheral edge 33 of the inclined rotor 30 into the annular rotary body. 20, and the medicine on the upper end peripheral part 23 is aligned by the horizontal transport by the rotation of the ring-shaped rotating body 20 and the aligning function of the regulation mechanism 70, and transported to the drop discharge port 14. It has become. Each part will be described below.

The annular rotating body 20 (see FIGS. 9 to 11) is roughly divided into a lower portion 21 whose hollow diameter increases upward and an upper portion 22 whose hollow diameter decreases upward. , put the upper part 22 on the lower part 21, and then connect both parts 21 and 22 with bolts or the like, so that the annular rotating body 20 itself is integrated (see FIG. 11(b)), and the inclined rotating body 30 Both become inseparable, and the axial rotation of the tilted rotor 30 is allowed, but if either the annular rotor 20 or the tilted rotor 30 is lifted, both 20 and 30 act as if they were one rotating container 20 + 30. are designed to move together.

The inclined rotating body 30 (see FIGS. 9 to 11) has a top surface that serves as the inner bottom of the rotating container 20+30. can be lifted together.
Also (see FIGS. 9(b) and 11(b)), on the upper surface of the inclined rotating body 30, the central portion 32 excluding the central projection 31 is recessed from the central projection 31 and the peripheral portion 33, and the inside of the rotating container 20+30 is recessed. increasing the space.

Furthermore, the upper surface of the peripheral edge portion 33 of the inclined rotating body 30 is processed into a loose sawtooth waveform that is useful for scooping up the medicine over the entire circumference (see FIGS. 9A and 10). It is in a so-called outer downward state in which the distance from the center is downward (see FIGS. 9(b) and 11(b)). In addition, the outer descent of the annular rotator 20 can be achieved at any portion of the peripheral edge portion 33, particularly at the highest position where the outer descent is the slowest, in a state in which the inclined rotator 30 is installed in the annular rotator 20 at an angle. Since the downward slope is maintained even at the portion above the upper end peripheral portion 23, it is useful to smoothly feed the scooped medicine to the upper end peripheral portion 23 of the annular rotating body 20 by rolling due to the inclination.

The bearing mechanism 40 (see FIGS. 9(b) and 11(b)) is composed of a plurality of members 41 to 43 which are distributed in various places. and rotation transmission members 42 and 43 each comprising a ring-shaped or annular body such as an O-ring made of hard rubber.
The passive member 41 brings the outer peripheral surface of the rotating body into contact with the outer peripheral surface or the lower surface of the annular rotating body 20 or the lower surface of the inclined rotating body 30 to fix the annular rotating body 20 and the inclined rotating body 30 in a state of easy rotation. It is dedicated to the bearing that holds it.

On the other hand, the rotation transmission members 42 and 43 are both attached to a rotation drive member 51 (to be described later) to exert a rotation transmission function. , and hold them in a fixed position in an easy-to-rotate state. In addition, since the support members 41 to 43 are all arranged in contact with the lower surface or the outer peripheral surface of the annular rotating body 20 and the inclined rotating body 30, the supporting mechanism 40 includes the annular rotating body 20 and the inclined rotating body 30. The rotating container 20+30 consisting of (1) can be properly set by being lowered from above and placed on the supporting members 41-43, and can be easily removed from the supporting members 41-43 by lifting the rotating container 20+30.

The rotation drive mechanism 50 (see FIGS. 9(b) and 11(b)) includes a rotation drive member 51 arranged below the rotary container 20+30 and a rotation drive motor 54 for axially rotating the rotation drive member 51. Although provided, the rotation transmission members 42 and 43 of the support mechanism 40 are also part of the rotation drive mechanism 50 as described above.
Specifically, the large-diameter external rotation transmission member 42 is externally mounted with its inner portion housed in an annular groove formed in the large-diameter portion 52 of the rotation drive member 51 (see FIG. 11(b)). In addition to supporting the ring-shaped rotating body 20, the ring-shaped rotating body 20 also has a rotation transmission function by friction transmission (see FIG. 9B).

In addition, the small-diameter external rotation transmission member 43 is externally mounted with an inner portion housed in an annular groove formed in the small-diameter portion 53 of the rotation drive member 51 (see FIG. 11(b)). In addition to supporting the tilting rotor 30, it also bears a rotation transmission function by friction transmission (see FIG. 9(b)).
Therefore, the rotation driving mechanism 50 rotates the rotation driving member 51 by the rotation driving motor 54, thereby rotating the annular rotating body 20 at a relatively high speed and rotating the inclined rotating body 30 at a relatively low speed. It is intended to make

The sorting member 60 (see FIGS. 9 to 11) is mainly composed of an elongated bar extending from the base end 61 of the swing fulcrum to the tip 62 of the swing end. It is supported above the peripheral wall 11 and the annular rotating body 20 by 63 so that the tip end portion 62 can swing up and down around it. The portion near the tip portion 62 is slightly bent, and in the normal state, the tip portion 62 is lightly placed on the peripheral edge portion 33 of the inclined rotating body 30 by its own weight in a state in which it faces obliquely downward. Most of the drug carried on the peripheral edge 33 without slipping down to the upper end peripheral edge 23 contacts the tip 62 and is returned to the central portion 32 of the inclined rotating body 30 by the biasing force of the reaction. However, if this is not done smoothly, the distal end portion 62 will swing and escape upward in order to avoid breakage of the drug.

The regulating mechanism 70 (see FIGS. 9 and 10(a)) includes a first regulating member 71 installed ahead of the sorting member 60 with respect to the rotation direction of the upper end peripheral edge portion 23 of the annular rotating body 20, and A second restricting member 72 installed further ahead, and a link mechanism 73 connected to both the first restricting member 71 and the second restricting member 72 via a pin-shaped rotation-permitting shaft member or the like. and a mold receptacle 74 which may contain sample agents.
Both the first regulating member 71 and the second regulating member 72 are located on the side of the peripheral wall 11 at the swinging center and at the swinging end on the upper peripheral edge 23 of the annular rotating body 20. The width of the medicine conveying path on the upper end peripheral portion 23 is narrowed from the outer peripheral side.

Moreover, both the first regulating member 71 and the second regulating member 72 can variably adjust the amount of narrowing of the medicine conveying path width above the upper end peripheral portion 23 by swinging. Since both the regulating members 71 and 72 swing simultaneously and in the same manner in accordance with the advancing and retreating direction, the amount of adjustment of the amount of narrowing of the medicine conveying path width by both the regulating members 71 and 72 is interlocked. Further, when the sample drug is accommodated in the mold storage space 74 and the link mechanism 73 is moved toward it, the link mechanism 73 advances in the longitudinal direction and the tip is brought into contact with the sample drug and stopped. Both the swinging end portion of the first regulating member 71 and the swinging end portion of the second regulating member 72 narrow the width of the medicine conveying path on the upper end peripheral portion 23 to the width corresponding to one medicine following the sample medicine. ing.

In addition, further forward than the restricting mechanism 70, the peripheral wall 11 is formed with a drop discharge port 14 penetrating vertically through the peripheral wall 11, into which the drug on the upper peripheral edge portion 23 of the annular rotating body 20 is dropped. A discharge guide 13 is also provided on the peripheral wall 11 in order to feed the liquid by the rotation of the annular rotating body 20 . The discharge guide 13 starts from the peripheral wall 11 at the rear of the drop discharge port 14, extends above the upper peripheral edge 23, and protrudes further above the peripheral edge 33 of the inclined rotating body 30 at its tip, so that it has an annular shape. The drug carried on the discharge guide 13 of the rotating body 20 is in contact with the side wall of the discharge guide 13 obliquely, then advances obliquely along the side wall and reaches the drop discharge port 14. - 特許庁.

Furthermore, at the leading end of the discharge guide 13, a conveying surface guide 12 is formed which extends downwardly and also forward to become the leading edge. Since the upper surface of the conveying surface guide 12 is substantially at the same height as the upper peripheral edge portion 23 of the annular rotating body 20 and is positioned on the inner peripheral side of the upper peripheral edge portion 23 , the upper peripheral edge portion of the annular rotating body 20 is 23, when it comes into contact with the discharge guide 13, it may drop toward the inclined rotor 30 or be caught between the annular rotor 20 and the discharge guide 13. It can be easily prevented from occurring.
Although illustration is omitted due to its detailed shape, the top peripheral edge portion 23 is formed to easily prevent the drug from rolling down to the drop discharge port 14 due to inertia or the like before being pushed out to the drop discharge port 14 by the discharge guide 13. The outermost peripheral portion of the upper surface is slightly raised.

Furthermore, although illustration is omitted, a controller responsible for controlling the operation of the rotary drive motor 54 and a power supply for supplying operating power to them are also provided inside the same housing or provided outside the housing. A photosensor or the like for detecting the drop of the medicine at the drop discharge port 14 is also attached, and the detection signal is transmitted to the controller and the tablet counter.
The rotation control of the controller starts from low-speed rotation, and shifts to high-speed rotation after detecting the discharge of the first medicine and then detecting the discharge of a predetermined number of medicines set in advance. In addition, the remaining number is calculated from the total number of medicines to be discharged and the number of medicines already discharged. Reverse rotation is also provided for prevention.

The operation and the like of the drug feeder 10 having such a configuration will be described with reference to the drawings. 12 and 13, (a) is a plan view and (b) is a longitudinal front view, and FIG. FIG. 13 shows the state where the aligned medicines 5 are fed from the upper end peripheral edge portion 23 to the drop discharge port 14. As shown in FIG. The medicines 5 may be referred to as mold medicines 5a, randomly accommodated medicines 5b, and sorted medicines 5c depending on the situation in which they are placed.

In order to sequentially feed a large number of drugs 5 using the drug feeder 10 (see FIG. 12), prior to that, the work of regulating the width of the drug transport path and the random injection of drugs are completed.
Of these, the work for regulating the width of the drug conveying path is performed by the operator selecting an appropriate one from among the many drugs 5 as the mold forming drug 5a, storing it in the mold storage space 74, and then attaching it to the link mechanism 73. This is accomplished by simply adjusting the position of the linkage 73 so that one end of the .

When this operation is performed, both the first restricting member 71 and the second restricting member 72 swing in conjunction with the link mechanism 73, and the swinging ends of the first restricting member 71 and the second restricting member 72 move the upper peripheral edge portion 23 of the annular rotating body 20. The width of the upper medicine conveying path is narrowed at two points to a point corresponding to the diameter of the mold medicine 5a.
Also, the random injection of the medicines can be done by the operator literally throwing a large number of medicines 5 into the rotary containers 20+30 from the upper opening of the ring-shaped rotating body 20 at random.
Then, the randomly stored medicines 5b that have been put in are naturally collected on the lower portion of the upper surface of the inclined rotating body 30. As shown in FIG.

This completes preparations for automatic operation, and when the drug feeder 10 is operated, for example, in a simple continuous feed mode, the rotary drive motor 54 will thereafter rotate at an appropriate speed under the control of the controller. Then, the rotary drive member 51 is axially rotated accordingly, and the rotary motion is transmitted to the annular rotating body 20 by friction transmission via the large-diameter exterior rotation transmission member 42, and the small-diameter exterior rotation transmission member 43 to the inclined rotating body 30, and the large diameter external rotation transmission member 42 and the small diameter external rotation transmission member 43 rotate in the same direction. The member 42 rotates at a higher speed than the small diameter exterior rotation transmission member 43 .

When the tilted rotator 30 rotates about its axis, the drug 5 that has been on the peripheral edge 33 of the tilted rotator 30 out of the randomly stored drugs 5b accumulated in the inner bottom of the rotating container 20+30 is pushed out of the sawtooth-shaped peripheral edge 33. It is scooped from a low position to a high position by a circular motion.
Most of the drug 5 carried to the point where the peripheral edge 33 is higher than the upper peripheral edge 23 of the annular rotating body 20 slides down or rolls due to the inclination of the peripheral edge 33 , causing the upper peripheral edge 23 to fall. move up.

On the other hand, the drug 5 remaining on the peripheral edge portion 33 of the inclined rotating body 30 because the upper end peripheral edge portion 23 is clogged with another preceding drug 5 or does not accidentally slide down or roll. is carried to the tip 62 of the sorting member 60 by further axial rotation of the tilting rotor 30, where it abuts the tip 62, and moves in the opposite direction to the upper end peripheral edge 23 by reaction to the abutment. As a result, the central portion 32 of the tilted rotating body 30 slides down along the tilted surface.
In this way, the excess medicines 5 and the like return to the randomly stored medicines 5b, so that the medicines 5 are fed into the medicine conveying path above the upper peripheral edge portion 23 at a frequency close to the appropriate amount, narrowed down to some extent.

Since the ring-shaped rotating body 20 rotates at a higher speed than the inclined rotating body 30, the drug 5 on the upper end peripheral edge 23 is displaced to some extent according to the difference in rotation speed when transferred from the peripheral edge 33. Although it varies, it is possible that, for example, when the drug 5 is small, some may be arranged in a vertical line, while others may be arranged horizontally or diagonally. When the medicines 5 are conveyed to the first regulating member 71 by the axial rotation of the annular rotating body 20, the medicines 5 in a line pass through as they are, but the medicines 5 in a row pass through the first regulating member 71. Because the medicine 5 inside is pushed out from above the upper end peripheral part 23 by the interference of the two and falls on the inclined rotating body 30 and returns to the randomly stored medicine 5b, the side-by-side arrangement is eliminated.

However, when there are many medicines 5 arranged side by side, there may be medicines 5 that pass through the tip of the first regulating member 71 in such a manner as to wrap around the medicines 5 due to the medicines 5 pushing each other or the like. In such a case, some of the medicines 5 that have passed through the first restricting member 71 may remain in an oblique horizontal arrangement. In any case, the drug 5 that has passed through the first regulating member 71 is then carried to the second regulating member 72 by the axial rotation of the annular rotating body 20, and is forced to align again in the same manner. Even if the state remains, it is only a slight one, and since it remains in a light state of slanted horizontal alignment, the horizontal alignment state can be quickly and sufficiently eliminated by the re-regulation.

Aligned medicines 5c thus clearing the double regulation and aligned in a row (see FIG. 13) are successively pushed into the discharge guide 13 by the circulatory motion of the upper end peripheral portion 23 accompanying the axial rotation of the annular rotating body 20. , and abuts against the outer side surface of the ejection guide 13 that obliquely intersects the drug transport path on the upper edge portion 23 .
Most of the aligned medicines 5c immediately advance along the contact side surface of the discharge guide 13 and are fed into the drop discharge port 14 in a line.

However, depending on the contact situation, some of the aligned drugs 5c may be repelled to the inner peripheral side on rare occasions. The conveying surface guide 12 prevents the sheet from dropping into the sheet or from being caught in the oblique portion between the upper end peripheral portion 23 and the ejection guide 13 .
In this way, all the aligned medicines 5c are fed into the drop discharge port 14 in a line without waste. Since the medicine 5 fed into the drop discharge port 14 is accelerated by gravity and the falling speed increases, the separation distance between the preceding and following medicines 5 is increased. By detecting the drug 5, the drug 5 can be accurately counted.

In addition to stopping the operation of the medicine feeder 10, when the processing of a large amount of the medicines 5 is completed by repeating such alignment and discharge of the medicines 5, or when the type of the medicines 5 is to be changed. Therefore, it is often necessary to clean the rotating container 20+30. In that case, first remove the uppermost peripheral wall 11 and the like, and then, for example, use the central protrusion 31 of the tilting rotor 30 as a handhold to remove the tilting rotor 30. When lifted, the rotary containers 20+30 come out together from the housing. Since the rotary container 20+30 is only supported by the support mechanism 40, it can be easily taken out and cleaned by washing or the like. In this way, cleaning after use can be completed easily and quickly, so that the work can be reversed to put it back in place for the next use.

Such a drug feeder is based on a double-rotation type drug feeder, that is, the rotating container is doubled inside and outside, and the upper end of the outer ring-shaped rotating body rotates from the inner inclined rotating body by rotating them. By carrying the solid medicine over the peripheral part and aligning the solid medicine with the regulating member, not only is there no need to provide a fixed straightening guide in the rotating body, but also the width of the medicine can be regulated. Among them, the storage capacity of medicines is large, and furthermore, the common range for medicines of various shapes and sizes is expanding, and the usage is also diversifying.

As one of the diversification of usage, sometimes a large amount of medicine exceeding the storage capacity of the ready-made medicine feeder is processed. In that case, currently, if it is possible to allocate a large number or multiple drug feeders to the same type of drug, it can be dealt with by distributed storage, etc., but only a few or a single drug feeder can be used for the same type of drug. Occasionally, mid-process medication must be replenished, resulting in a premature pause in the operation of the medication feeder.
Even if the drug feeder to be replenished is used alone, if it is installed in a drug packaging machine together with a large number of drug feeders containing various drugs, the large number of drug feeders will stop working together. Therefore, the impact is large.
Therefore, it is a technical problem to realize a drug feeder that can easily increase the drug storage capacity of the rotary container while following the double-rotation type drug feeder.

The drug feeder of the present invention (Solution Means 1) was invented to solve such problems. an inclined rotating body mounted inside the annular rotating body in a state capable of axial rotation about an inclined line and closing a hollow of the annular rotating body; and an upper end of the annular rotating body from above due to the rotation of the inclined rotating body. A drug feeder comprising: a regulating member for aligning solid drugs carried on a peripheral portion when the annular rotating body rotates; The plate portion can be attached to and detached from the peripheral wall from above, and has a through hole positioned above the annular rotating body when attached. and the cylindrical portion protrudes upward from the plate portion so as to extend the through hole upward.
The above vertical lines are imaginary lines, and the vertical lines described above are typical.

Further, in the drug feeder of the present invention (solution 2), the drug feeder of the solution 1, the container extending body also has a drooping portion, and the plate portion is attached to the peripheral wall. and the drooping portion is positioned laterally of the restricting member and reaches the inside of the annular rotating body.

Further, the drug feeder of the present invention (solution 3) is the drug feeder of the solutions 1 and 2, further comprising a lid that opens and closes the upper side of the peripheral wall, and when the lid is closed, the container extending body The upper end opening of the cylindrical portion of the lid is closed by the lower surface of the lid to a state where the medicine cannot pass.

In such a drug feeder of the present invention (Solution 1), a double-rotation type drug feeder is used as a basis, and a container extending body provided with a plate portion that can be attached to and detached from the peripheral wall from above is introduced. As a result, when the drug storage capacity of the rotary container is insufficient, the drug storage capacity of the rotary container can be easily increased by attaching the plate portion to the peripheral wall.
Along with the mounting of the plate portion, the through hole of the plate portion was positioned above the annular rotating body, and the cylindrical portion stood further above the through hole, so that the opening of the rotary container was extended upward. This is because the state is the same as that in the case of increasing the amount of medicine contained in the rotating container.
Therefore, according to the present invention, it is possible to realize a drug feeder that can easily increase the drug storage capacity of the rotating container while following the double-rotation type drug feeder.

Further, in the drug feeder of the present invention (Solution 2), the extending body of the container is also provided with a hanging part so that the hanging part is located on the side of the regulating member and reaches the inside of the annular rotating body in the attached state. As a result, it is possible to easily and accurately prevent the occurrence of an inconvenient situation in which the medicine is tilted from inside or below the cylindrical portion of the container extending body toward the portion of the upper end peripheral portion of the annular rotating body on which the regulating member acts. is prevented.

Furthermore, in the drug feeder of the present invention (Solution 3), the cover that opens and closes the upper side of the peripheral wall substantially opens and closes the upper end opening of the cylindrical portion of the elongated container. It is possible to simply and accurately prevent the medicine from jumping out of the container extension body even when the medicine is put into the container until it is nearly full.

A specific form for carrying out such a drug feeder of the present invention will be described in Example 1 below.
Embodiment 1 shown in FIGS. 1 to 8 embodies all of the above solutions 1 to 3 (claims 1 to 3 at the time of filing the application).
In the drawings, for the sake of clarity, housing panels, bolts and other fasteners, hinges and other connectors, electric circuits such as motor drivers, and electronic circuits such as controllers are omitted from the drawings. The illustration focuses on what is necessary and related to the explanation of the invention.

A specific configuration of Example 1 of the drug feeder of the present invention will be described with reference to the drawings. The overall configuration of the drug feeder 100 of Embodiment 1 (see FIGS. 7 and 8) generally follows the overall configuration of the drug feeder 10 described above (see FIG. 9). The ejection guide 13, the drop ejection port 14, the support mechanism 40, the housing in which they are placed or accommodated, and the overall arrangement of members are almost the same as those described above, so repeated explanations are omitted. Omit.

In addition, the annular rotating body 20, the tilting rotating body 30, the rotation driving mechanism 50, the sorting member 60, and the regulating mechanism 70 (see FIGS. 9 to 11) are each modified to provide a new annular rotating body 200. , tilting rotator 300, rotary drive mechanism 500, sorting mechanism 600, and regulating mechanism 700 (see FIGS. 1 to 8). Along with this, the double-rotation type rotary container 20+30 is changed to the double-rotation type rotary container 200+300. Furthermore, the container extension 800 and the large lid 110 (see FIG. 7) are newly added and will also be described.

The tilting rotor 300 shown in FIG. 1 is obtained by modifying the tilting rotor 30 described above. FIG. 1 shows the structure of the inclined rotor 300 of the rotary container 200+300 of the medicine feeder 100. FIG. It is a plan view (as viewed from arrow B) and a front view (as viewed from arrow C), and (b) is an external perspective view of the tilted rotor 300. FIG.
The inclined rotating body 300 is mainly composed of a generally disk-shaped round plate portion 310 (see FIG. 1(a)), and maintains the above-described central projection 31 at the center of the upper surface (see FIG. 1(b)). ), and a rotating shaft portion 370 projecting downward from the center of the lower surface (see FIG. 1(b)).

The round plate portion 310 (see FIG. 1(a)) has a generally flat top central portion 320 around the central projection 31 . The upper central portion 320 may be recessed from the upper peripheral edge portion 330 like the central portion 32 of the tilted rotating body 30 described above. flat.
On the surface of the central portion 320 of the upper surface, parallel wavy unevenness 321 is formed by arranging and carving a large number of thin and shallow linear grooves extending in a generally radial direction (three locations with different circumferential directions in the figure). Since the function of promoting the rolling of the medicine on the slope is strengthened, the effect of agitating the medicine and the effect of guiding it to the upper peripheral edge portion 330 are exhibited.

In addition, the round plate portion 310 (see FIG. 1) has a transfer portion 340 and a push-up portion 350 formed on an upper peripheral edge portion 330 that encircles the central portion 320 of the upper surface. The delivery portions 340 and the push-up portions 350 are alternately formed in the circumferential direction (in the drawing, six portions are formed in different circumferential directions).
The delivery part 340 is a local chamfered outer downward notch that is larger than the drug to be handled, and the downward downward angle is approximately 45°, approximately 20° to 30°. greater than the tilt angle when attached. Therefore, even if the tilted rotating body 300 is mounted in the annular rotating body 200 in an inclined state, even if the tilting of the transferring section 340 approaches the horizontal when the tilting body 300 rotates in that state, the tilting of the transferring section 340 will be the closest to the horizontal. The outer downward angle is generally maintained at 15° or more. The delivery portion 340 also has a pattern similar to that of the parallel wave-shaped unevenness 321 described above.

The push-up portion 350 is a raised portion located on the rear end side of both circumferential ends of the delivery portion 340, does not have an outward downward slop like the delivery portion 340, and is at the same height as or higher than the center extension surface 351. standing up to the point. A push-up portion 350 whose rise is the same as the center extension surface 351 and a push-up portion 350 whose rise extends beyond the center extension surface 351 to the front surface of the base portion 361 of the projection 360 are alternately formed in the circumferential direction. (In the illustrated one, the projections 360 are alternately arranged with respect to the six delivery portions 340 in different circumferential directions).
The convex portion 360 includes a base portion 361 that extends upward from the boost portion 350 on the rear end side of the delivery portion 340 higher than the central portion 320 of the upper surface, and an extension portion that extends the upward convex portion to the inner peripheral side of the delivery portion 340. 362, and may be attached to all the delivery parts 340 and boost parts 350, but in this embodiment, they are attached every other one.

The ring-shaped rotating body 200 shown in FIGS. 2 and 3 is obtained by modifying the ring-shaped rotating body 20 described above. FIG. 2 shows the structure of the annular rotor 200 of the drug feeder 100, in which (a) is a vertical cross-sectional view of the entire annular rotor 200, and (b) is a longitudinal cross-section of an enlarged right end portion of the upper portion 220 thereof. FIG. (c) is a longitudinal cross-sectional view of the annular rotating body 200 specifying the tilted state.
3A is a plan view of the upper peripheral edge portion 230 of the annular rotating body 200, and FIG. 3B is an enlarged view of a part of the upper peripheral edge portion 230. FIG.

The ring-shaped rotating body 200 (see FIG. 2(a)) basically inherits the configuration of the ring-shaped rotating body 20 described above, but the upper portion 220 and the lower portion 210 are integrated to form the bottom of the bowl-shaped body. It looks like it was removed. Moreover, the diameter of the hollow is the largest at the upper edge portion 230 at the highest position, and the diameter of the hollow decreases as it descends from there. Therefore, the inclined rotor 300 can be freely inserted into or removed from the hollow of the ring-shaped rotor 200, facilitating assembly and parts replacement. A chamfer 232 is formed along the circumference of the upper peripheral edge portion 230 of the upper portion 220 (see FIG. 2(b)). The inclination angle α of the chamfer 232 is, for example, about 7°, which is highlighted in the figure.

Also (see FIG. 2(c)), the vertical line 201 (two-dot chain line in the figure) corresponding to the central axis of rotation of the upper part 220 and thus the ring-shaped rotating body 200 is inclined by an angle β from the vertical line (one-dot chain line in the figure). there is This inclination angle β, which is also highlighted in the drawing, is suppressed to, for example, about 3.5° so as not to impair the drug delivery function, which is smaller than the above-described inclination angle α.
Therefore, the inclination of the chamfer 232 from the horizontal is the maximum inclination (α + β) when the upper end peripheral portion 230 rotates (to the left in the figure) and the minimum inclination (α -β), but since the inclination angle α of the chamfer 232 is greater than the inclination angle β of the annular rotating body 200, the downward state is always maintained toward the outer circumference.

The direction of the inclination (β) of the vertical line 201 is not shown in the drawing, but the height (vertical position) of the upper surface (drug transport path) of the upper end peripheral edge portion 230 of the annular rotating body 200 is the height of the drop discharge port 14. It is in the direction of getting higher in the vicinity.
The inclination (β) may be embodied individually, for example, by how the annular rotating body 200 is attached in the housing of the drug feeder 10. However, since the inclination (β) is small, for example, the housing of the drug feeder 10 By inclining the upper surface of the shelf board or the like by an angle β, it is also possible to simply implement them collectively.

Further (see FIG. 3), a large number of grooves 231 are arranged in a circumferential direction at equal pitches on the upper surface (drug transport path) of the upper peripheral edge portion 230 of the upper portion 220 of the annular rotating body 200 .
Each of these grooves 231 is carved into a shape close to a rhombus or a spindle shape, and the longitudinal direction is oriented in the radial direction, the width is reduced at both ends in the radial direction, and the width is expanded in the middle in the radial direction. The medicine is easily settled at the widened portion. Also (see FIG. 2B), the depth e of the deepest portion of the groove 231 is deeper than the depth d of the chamfer 232 described above. Furthermore (see FIGS. 2(b) and 3), the edge of the groove 231 near the outer diameter extends to the chamfer 232, so that the drug can smoothly move from the groove 231 to the chamfer 232. It's becoming

In addition (see FIGS. 2(b) and 3), a large number of engravings 233 are also formed in the inner peripheral portion of the upper surface of the upper end peripheral portion 230. As shown in FIG. Each of the engravings 233 is located between the adjacent grooves 231, 231, and has a curved shape that becomes deeper toward the inner circumference. It helps to quickly return the collected medicine, which tends to roll, from the medicine transport path of the annular rotor 200 to the inner tilted rotor 300 .
These grooves 231, chamfers 232, and engravings 233 are smooth surfaces so as not to hinder the movement of the drug. In order to prevent excessive slipping, the surface is roughened by blasting.

A regulation mechanism 700 shown in FIG. 4 is obtained by modifying the regulation mechanism 70 described above. 4 shows the structure of the regulating mechanism 700 of the chemical feeder 100. FIG. 4A is a plan view of the regulating mechanism 700 when a large mold chemical 5a is placed in the mold storage space 740, and FIG. FIG. 11 is a plan view of the regulation mechanism 700 when the mold agent 5a is placed on the mold storage place 740; In addition, FIG. 7(c) is a drawing relating to both the first regulating member 710 and the second regulating member 720, the upper part is a plan view and an end view, the middle part is a front view, and the lower part is a bottom view. FIG. 4 is an end view;

The regulating mechanism 700 (see FIG. 4A) takes over the previously described regulating mechanism 70, while the link mechanism 73 is generally taken over as it is. are improved to form a first regulating member 710, a second regulating member 720, and a die storage area 740, respectively.
Since the first and second regulating members 710 and 720 have the same shape, one 710 will be described in detail. 11 side, the swinging end on the right end in the figure is positioned above the upper end peripheral portion 230 of the annular rotating body 200, and the drug transport path above the upper end peripheral portion 230 according to the longitudinal advance and retreat of the link mechanism 73. It exerts a lateral width regulating function that narrows the width from the outer peripheral side (see FIGS. 4(a) and 4(b)).

The first restricting member 710 (see FIG. 4(c)) has a modified inner peripheral side surface, and the inner peripheral side surface follows the inner peripheral side surface of the first restricting member 71 described above. In addition to the lower portion 711 that has a regulating function, an upper portion 712 that was not included in the first regulating member 71 is also formed. The upper portion 712 protrudes further inward than the lower portion 711 , and an inclined surface is formed between the upper portion 712 and the lower portion 711 . Therefore, in the first restricting member 710, the lower portion 711 performs a strict lateral width restricting function according to the state of the link mechanism 73, and the upper portion 712 moderately restricts the height. The second regulating member 720 is also the same.

In addition (see FIG. 4A ), in the regulation mechanism 700 , the mold storage space 74 is modified to become a mold storage space 740 , and a spring 730 is attached to bias the link mechanism 73 toward the mold storage space 740 . By bringing the tip of the link mechanism 73 into contact with the mold drug 5a (sample drug) and stopping it, the lower tiers 711 and 712 of the swinging ends of the regulating members 710 and 720 extend the width of the drug conveying path on the upper edge portion 230. The mold storage space 740 also inherits the function of narrowing down to the size of one drug passage. The small lid 741 is a lid that can be opened and closed, and is made of a transparent member, so that it is useful for preventing forgetting to store or take out the molding agent 5a. The set screw 742 is for stopping the closed small lid 741 so that the closed small lid 741 does not open due to the biasing force of the spring 730 .

The sorting mechanism 600 shown in FIG. 5 is a modification of the sorting member 60 already described. FIG. 10B is a front view of the first sorting member 610 of the sorting mechanism 600, and (c) is a front view of the second sorting member 620 of the sorting mechanism 600. FIG. be.

The sorting mechanism 600 (see FIG. 5(a)) is a first sorting member arranged upstream of the regulation mechanism 700 in the same manner as the sorting member 60 described above in the drug transport path of the upper end peripheral portion 230 of the annular rotating body 200. 610, and a second sorting member 620, which is arranged at a position in line with the regulation mechanism 700 in the medicine conveying path, unlike the sorting member 60, and the plurality of these members exert a sorting function in multiple stages. It has become something to do.
Both members 610 and 620 are attached to a plate that includes the discharge guide 13 and supports the regulation mechanism 700 in the same manner as the sorting member 60 described above.

The first sorting member 610 (see FIGS. 5A and 5B) includes a short support member 611 whose vertical position can be adjusted by a manual screw mechanism, and a support member 611 attached to a portion near the tip of the support member 611. It is equipped with a front hanging object 612 that moves up and down along with it.
The front hanging object 612 (see FIG. 5(b)) is formed by loosely connecting a plurality of large balls 613 (two spheres in the figure) into a chain shape, and a commercially available ball chain or the like can be used easily and easily. It can be implemented inexpensively. In the first sorting member 610, two front hanging objects 612 hang side by side from the support member 611 above the drug conveying path of the upper end peripheral portion 230, and the lower ends of the front hanging objects 612 are usually slightly higher than the height of the drugs. The vertical position is adjusted so that the

The second sorting member 620 (see FIGS. 5(a) and 5(c)) consists of a long support member 621 whose vertical position can also be manually adjusted, and a portion near the tip of the support member 621 attached to follow the support member 621. A middle hanging object 622 and a rear hanging object 632 that move up and down, and a manual adjustment mechanism 650 that adjusts the vertical position of the support member 621 .
The middle hanging object 622 (see FIG. 5(c)) is formed by loosely connecting a plurality of central balls 623 (three spheres in the figure) to form a chain. is increasing.
The rear hanging object 632 is also formed by loosely connecting a plurality of small beads 633 (seven in the front and six in the back in the figure) into a chain shape, and the small beads 633 are made smaller and the number of connected ones is increasing.

The manual adjustment mechanism 650 manually lifts the support member 621 to widen the gap between it and the lower limit setting mechanism 651 , and then places the mold agent 5 a (the mold placed in the mold storage space 740 described above) on the lower limit setting mechanism 651 . A chemical agent 5 different from the chemical agent 5a for mold but having the same shape) is placed, and then the supporting member 621 is manually lowered to a point where it lightly touches the chemical agent 5a for the mold. It is designed to come to a position corresponding to the mold chemical 5a.
A scale member 652 is attached to the lower limit setting mechanism 651 (see FIG. 5(c)). The restricted height by the second sorting member 620 adjusted by the adjusting mechanism 650 is also shown. In addition, the adjustment of the vertical position of the support member 621 is accompanied by the measurement and display of the mold agent 5a, which serves as a reference for the adjustment of the first sorting member 610. FIG.

Further, the positional relationship and division of roles among the above-described front hanging object 612, middle hanging object 622, and rear hanging object 632 will be described.
Both of the two front hanging objects 612 hang above the drug transport path of the upper end peripheral part 230 and are arranged in the transverse direction of the drug transport path, which is the radial direction of the upper end peripheral part 230 . The lower end position of the front hanging object 612 depends on the adjustment policy, so it cannot be said unconditionally. made high. Although the large ball 613 is heavy and the overlapping of the drug is efficiently eliminated, the large ball 613 at the lower end, which is the free end, escapes due to the deformation of the connection part immediately above, so the impact on the drug is less.

When the medicine is spherical, it tends to roll easily and its position is not stable in many cases. Pass between 612. Also, when the medicine is slightly displaced laterally from the center, the misaligned front hanging object 612 and the medicine lightly interfere with each other, causing the medicine to move to the center (or the upper end of the annular rotating body 200 for a medicine that rolls easily). (at the widened portion of the groove 231 of the peripheral portion 230). On the other hand, when the medicines are greatly displaced from the center, some medicines are brought to the center depending on the degree of contact, but most of the medicines are pushed out from the upper peripheral edge portion 230 and return to the inclined rotating body 300. - 特許庁

The two middle hanging objects 622 are straddling sorting members whose supporting members 621 straddle the regulating mechanism 700, and both of the middle hanging objects 622 hang above the drug conveying path of the upper end peripheral edge portion 230 and are regulated. It is positioned beside the mechanism 700 (particularly the second restricting member 720) and forms a side-by-side hanging object.
In addition, both middle hanging objects 622 are positioned above the medicine conveying path of the upper edge portion 230, and are arranged obliquely with respect to the medicine conveying path.

Further, the standard setting of the relationship between the support member 621 and the manual adjustment mechanism 650 is such that the lower end position of the middle hanging member 622 is slightly lower than the drug on the drug transport path.
Therefore, if the medicines overlap on the medicine conveying path, the middle hanging object 622 has the function of eliminating the medicine overlap by interfering with the middle ball 623 against the upper medicine. The medicine aligning function on the medicine conveying path is strengthened by returning the medicine that happens to be placed on the inner peripheral side of the medicine conveying path in a slanted side-by-side state to the center of the medicine conveying path or returning it to the inclined rotating body 300. It also exhibits the function of

Of the two trailing hanging objects 632 (see FIG. 5(a)), one (the hexagon at the back in the figure) hangs above the inner peripheral side of the drug transport path of the upper end peripheral edge 230, and the other (the front in the figure) hangs down. 7) deviate from the upper end peripheral edge portion 230 above the medicine conveying path, hang down above the outer peripheral side of the inclined rotating body 300, and are arranged in the transverse direction of the medicine conveying path.
Moreover, as the height of the support member 621 is adjusted by the manual adjustment mechanism 650, the lower end of one of the rear hanging members 632 is slightly lower than the lower end of the middle hanging member 622, and the lower end of the other rear hanging member 632 is lowered. The position is to be lowered further.
Therefore, the first sorting member 610 with the large balls 613, the middle hanging object 622 with the middle balls 623, and the rear hanging object 632 with the small balls 633 are arranged in order of the size of the balls. ing.

Further (see FIG. 5(a)), at least the rear hanging object 632 on the inner peripheral side (in the figure, the seven-link object on the front) is made of a magnetic material such as iron as the material of the small ball 633 . Correspondingly, an attracting member 640 made of a permanent magnet or the like is attached by fitting or the like to a portion of the second restricting member 720 that is close to the trailing hanging object 632 . Since the attracting force adds to the force of gravity, the trailing hanging object 632 exerts a gentle but effective reaction force on the medicine coming into contact with it from above the medicine conveying path. It's becoming As a result, the medicine that has been separated from the second regulating member 720 approaches the second regulating member 720, so that the function of the second regulating member 720 is strengthened. Such a trailing hanging object 632 emphasizes strengthening of the lateral width regulation of the medicine of the second regulation member 720 rather than its own function of regulating the height of the medicine.

The container stretcher 800 shown in FIG. 6 is newly added. 6 shows the structure of the container extension body 800 of the drug feeder 100, (a) is a perspective view, (b) is a bottom view, and (c) is a side view.

The container extending body 800 (see FIG. 6) includes a plate portion 810 in which a through hole 811 is formed which is approximately the same as or slightly smaller than the hollow of the upper end peripheral edge portion 230 of the annular rotating body 200, and the peripheral edge portion of the through hole 811 is formed as a lower end. It comprises a cylindrical portion 820 rising upward and a hanging portion 830 projecting downward with a part of the peripheral portion of the through hole 811 as an upper end.
The plate portion 810 can be attached to and detached from the peripheral wall 11 directly or indirectly via a plate on which the discharge guide 13 is formed. Positioned above the body 200 and the tilted rotating body 300, the cylindrical portion 820 protrudes from the plate portion 810 while expanding slightly upward, and extends the through hole 811 upward, thereby increasing the amount of medicine that can be stored. ing.

In addition, when the plate portion 810 is attached to the peripheral wall 11, the hanging portion 830 enters the inside of the annular rotating body 200 (at least the hollow inside of the upper end peripheral portion 230), and the restriction mechanism 700 (especially the first By being laterally adjacent to the restricting member 710 and the second restricting member 720), the drug in the barrel 820 is prevented from avalancheing into the restricting mechanism 700 and the upper rim 230 therearound. At the same time, the drug removed from the upper peripheral edge portion 230 before the discharge guide 13 can smoothly return to the inclined rotating body 300 .
Furthermore, a bulge 812 is formed in a part of the through hole 811 (see FIG. 6(b)), and a bulge 821 is also formed in the corresponding part of the cylindrical portion 820 (see FIG. 6(a)). ), unwanted interference with the ascending portion of the tilted rotor 300 is avoided, and the drug can be smoothly transferred from the tilted rotor 300 to the annular rotor 200 .

The large lid 110 shown in FIG. 7 is also newly added. FIG. 7 shows the overall structure of two drug feeders 100, 100, one equipped with a container extension body 800 and one without a container extension body 800, and FIG. FIG. 1B is an external perspective view of the drug feeder 100 with the large lid 110 closed.

The large lid 110 is connected to the upper surface of the peripheral wall 11 or the plate forming the discharge guide 13 through a hinge member so that the upper side of the peripheral wall 11 can be opened and closed. A bistable spring or the like is incorporated in the hinge member so that the large lid 110 is stabilized in either the fully open state or the fully closed state.
Also, the large lid 110 is made of a transparent or translucent member so that the operating conditions of the tilting rotor 300 and the like can be visually confirmed even when the lid is closed.

Furthermore, in the drug feeder 100 equipped with the large lid 110 and the container extension body 800, when the large lid 110 is closed, the lower surface of the large lid 110 touches the upper end of the cylindrical portion 820 of the container extension body 800 until it is just before contact. Since the depth of the large lid 110 and the height of the container extending body 800 are designed to be close to each other, when the large lid 110 is closed, the upper end opening of the cylindrical portion 820 of the container extending body 800 is exposed to the lower surface of the large lid 110. is closed until the drug cannot pass through.
As shown in the drawing, a hinge member is provided behind the drug feeder 100 (on the right rear in the drawing), and when the large lid 110 is lowered forward, the drug feeder 100 closes and the large lid 110 is lifted backward so that the drug feeder 100 opens. It is easy to use even if a plurality of drug feeders 100 are arranged side by side, but the large lid 110 may be opened in another direction.

The rotary drive mechanism 500 shown in FIG. 8( a ) is a modification of the rotary drive mechanism 50 described above, and the figure shows the internal structure of the drug feeder 100 incorporating the rotary drive mechanism 500 . Also, the controller 570 and the like (control section) shown in FIG. 8(b) are obtained by extending the above-mentioned rotational drive control function, and FIG. 8 is a block configuration diagram related to the rotational drive control.

The rotation drive mechanism 500 (see FIG. 8A) includes a rotation drive member 511 and a rotation drive member 512 that replace the rotation drive member 51, a rotation drive motor 541 and a rotation drive motor 542 that replace the rotation drive motor 54, and a new It is provided with an additional tilted rotating body attachment detection means 550 and a drug dropping detection means 560 indicated by a reference numeral. The rotary drive motor 541 rotates the annular rotary body 200 through the rotary drive member 511, and the rotary drive motor 542 rotates the tilt rotary body 300 through the rotary drive member 512. Since the system is divided into two systems, the annular rotating body 200 and the inclined rotating body 300 can be independently driven. Further, both the rotation driving motor 541 and the rotation driving motor 542 employ motors that can selectively switch the direction of rotation between forward rotation and reverse rotation according to the control of the controller 570 . Therefore, the rotation driving mechanism 500 can individually reverse the rotation directions of the annular rotating body 200 and the inclined rotating body 300 .

The tilt rotating body mounting detection means 550 is composed of a photo sensor or the like attached to a shaft support portion of the rotating shaft portion 370 of the tilt rotating body 300. When the tilt rotating body 300 is properly mounted, the rotating shaft portion is detected by the sensor. 370 is located, the rotating shaft portion 370 is provided in a position and posture such that if the inclined rotating body 300 is removed or attached but the attached state is inappropriate, the rotating shaft portion 370 will be deviated from the sensor detection destination. Attachment/detachment of the rotor 300 is detected.
The drug drop detection means 560 is composed of a photosensor or the like facing the drop path of the drug extending downward from the drop discharge port 14, and after aligning with the upper end peripheral edge 230 of the annular rotating body 200, the drug is sequentially discharged through the drop path. It is designed to detect the falling state of the drug that has been applied.

The controller 570 (see FIG. 8(b)) is a control circuit (control means) mainly composed of a microprocessor, and receives various instructions such as an initialization instruction and a drug discharge instruction from an operation unit (not shown) or a higher-level device, and operates independently. Rotation control of a pair of drivable rotary drive motors 541 and 542 is performed. For this purpose, the rotation direction and rotation speed of the rotation drive motor 541 and the rotation directions and rotation speeds of the rotation drive motors 541 and 542 are adjusted by referring to the presence or absence of the initialization instruction and the detection result of the medicine dropping detection means 560. and a drug discharge operation control program (medicine discharge operation control means) for sequentially discharging the drug, and a drug number management program (drug number management means) for discharging the number of drugs specified by the drug discharge instruction. there is

In the control by the drug number management program, the drug size is changed when an initialization instruction issued immediately after the drug feeder 100 is detached or powered on, or after the drug feeder 100 is replenished or reset, or after the drug discharge time-out is received. It is supposed to clear the estimated value. Further, by monitoring the detection result of the inclined rotating body mounting detecting means 550, it is determined whether or not the inclined rotating body 300 and the ring-shaped rotating body 200 are properly equipped. Management processing is also performed. That is, in this medicine number management process, the medicine ejection operation control program is started, the detection result of the medicine drop detection means 560 is monitored, the number of medicines discharged is grasped, and only the number of medicines specified by the medicine discharge instruction is detected. When the drug is discharged, the operation of the drug discharge operation control program is stopped.

In the control by the drug discharge operation control program, the estimated value of the drug size is confirmed, and when the estimated value is cleared, an initial operation is performed before obtaining the estimated value of the drug size. During this initial operation, the rotation speed of the rotary container 200+300, which is the combination of the annular rotor 200 and the tilted rotor 300, is first started at a high speed and then switched to a low speed. The preceding high-speed rotation is only for an assumed time until the first medicine transfers from the tilted rotor 300 to the annular rotor 200 in the drug feeder 100 in the initial state, for example, the time for the tilted rotor 300 to make a quarter turn. , is done. The next low-speed rotation is performed at such a low speed that even a drug that rolls easily does not go excessively to the drop discharge port 14 by force until the first dropped drug is detected by the drug drop detecting means 560. - 特許庁By doing so, it is possible to shorten the required time while avoiding excessive discharge even at the stage where the size of the medicine is unknown.

In addition, in the control by the drug ejection operation control program, each time the drop of the drug is detected by the drug drop detection means 560, the drug number management program is notified that one drug has been discharged. is cleared, the estimated value is also set. Specifically, the medicine detection time length is measured when the falling medicine is detected for the first time, and the measured value is used as it is or a value obtained by multiplying the measured value by a predetermined constant is adopted as the estimated value of the medicine size. done. This completes the initial operation.

After the estimated value has been set or when the estimated value has already been set, steady operation is performed under the control by the medicine discharge operation control program. In this steady operation, the rotation speed of the rotating container 200+300 is variably controlled according to the estimated drug size. Specifically, feedback control is performed using, for example, the reciprocal of the above estimated value as it is or a value obtained by multiplying it by a constant as the control target value for the rotary containers 200+300. Further, when the drug number management program instructs to stop the operation, the control of the drug discharge operation control program does not stop the rotation of the rotary container 200+300 suddenly but gradually decelerates it to prevent excessive rolling of the drug. , and reverse rotation is also performed to prevent excessive drop of medicine.

The reverse rotation of the rotating container 200+300 is performed when the number of medicines instructed by the medicine discharge instruction has been discharged.
Therefore, for example, when a medicine discharge instruction is issued from a medicine packing machine of a host device, a so-called reverse discharge operation is performed in units of one package.
In addition, the reverse rotation of the rotating container 200+300 can be performed by rotating both the annular rotating body 200 and the inclined rotating body 300 in reverse. Only the rotating body 300 is rotated slightly in the reverse direction.

The manner of use and operation of the drug feeder 100 of Example 1 will be described with reference to the drawings. The details of the drug feeder 10 that follow the above-mentioned items will be briefly described, and the improvements and new items will be mainly described in detail below.

First, if the rotating container 200 is properly mounted and the tilting rotor 300 is not properly mounted, the tilting rotor mounting detecting means 550 cannot detect the rotation shaft portion 370 of the tilting rotor 300. An alarm or the like is issued, so if you notice it, remount the rotating container 200+300.
To sequentially feed a large number of drugs 5 using the drug feeder 100, the large lid 110 is opened (see FIG. 7(a)), and if the amount of the drugs 5 does not exceed the capacity of the rotating containers 200+300, the container Although it is not necessary to mount the extending body 800 (see the right front drug feeder 100 in FIG. 7A), if the amount of the drug 5 exceeds the capacity of the rotating container 200+300, the container extending body 800 is attached ( 7(a), the medicine feeder 100 on the far left of FIG. 7(a)), and a required number or more of the medicines 5 are randomly fed into the rotary container 200+300 (the medicines 5 are shown in FIG. 12 and FIG. Since it conforms to FIG. 13, it is omitted here).

In addition, before or after the medicine is put in, adjustment work related to width regulation on the medicine conveying path by the regulation mechanism 700 (see FIG. 4) and adjustment related to height regulation on the medicine conveying path by the sorting mechanism 600 are performed. Work (see Figure 5). Even if the container extension body 800 is attached, the mold storage space 740 of the regulation mechanism 700 and the manual adjustment mechanism 650 of the sorting mechanism 600 are not hidden (see FIG. 7). can be adjusted similarly.
The width regulation of the regulation mechanism 700 is adjusted (see FIGS. 4A and 4B) by placing the mold agent 5a on the mold storage area 740, closing the small lid 741, and then tightening the set screw 742. The medicine 5a is securely fixed, the set state of the mold medicine 5a can be easily visually confirmed, and the bias of the spring 730 facilitates the alignment of the two restricting members 710 and 720. Precisely done.

Adjustment of the height regulation by the second sorting member 620 of the sorting mechanism 600 (see FIGS. 5(a) and 5(c)) is carried out manually after placing another mold agent 5a on the lower limit setting mechanism 651. By lowering the mechanism 650 and sandwiching the mold agent 5a, this can be easily and accurately performed. In most cases, this is sufficient, but when it is desired to make fine adjustments based on test runs or previous actual runs, the mold agent 5a is removed if necessary, and the support member 621 is slightly raised or lowered with reference to the scale.
Further, (see FIGS. 5(a) and 5(b)), adjustment of the height regulation by the first sorting member 610 of the sorting mechanism 600 is performed manually while referring to the scale member 652 indicating the size of the mold agent 5a. By making adjustments, this can also be done easily and accurately.

After all the preparatory work is completed, the large lid 110 is closed (see FIG. 7(b)) to prepare for the sequential discharge of the drug. When the large lid 110 is closed, the peripheral wall 11 and the top of the rotating container 200+300 are closed, and the upper end opening of the cylindrical portion 820 of the container extension body 800 is substantially sealed to prevent the drug 5 from spilling. In addition, an initialization instruction is issued according to the opening/closing operation of the large lid 110 or manual operation (see FIG. 8(b)). move on. However, when the drug feeder 100 performs the discharge operation, the condition is imposed that the tilted rotating body mounting detection means 550 detects the rotating shaft portion 370 of the tilted rotating body 300. Therefore, the sequential discharge of the drug is It is performed only in safe conditions where the rotating container 200+300 is properly mounted (see FIG. 8(a)).

When the medicine feeder 100 is ready for the sequential discharge of the medicine, when the medicine discharge instruction reaches the controller 570, the medicine discharge operation control of the medicine discharge operation control program is performed under the medicine number management of the medicine number management program. .
Initially, the drug size estimate is cleared, so an initial operation is performed and rotation of the rotary container 200+300 first begins at a high speed. However, even though it is said to be high speed, it is not so high that the fragile chemical agent 5 suffers damage such as crumbling or chipping on the surface or the like.
Then, when the first drug is transferred from the tilted rotor 300 to the annular rotor 200, the rotation of the rotary container 200+300 slows down. Therefore, although the first drug 5 is sent onto the ring-shaped rotating body 200 relatively early, it does not lead to an undesirable situation in which even a drug that easily rolls over and goes to the drop discharge port 14.例文帳に追加

During low-speed rotation, the drug 5 cannot be expected to run up the inclined inner surface of the annular rotating body 200 with the force of the peripheral portion of the inclined rotating body 300. is formed (see FIG. 1), the drug 5 drops from the upper central portion 320 of the tilted rotor 300 when it descends as the tilted rotor 300 rotates. Then, as the delivery part 340 rises with the further rotation of the inclined rotating body 300, the drug 5 in the delivery part 340 is pushed up by the boost part 350 on the rear side.
Although the medicine 5 is carried onto the annular rotating body 200 by the inclined rotating body 300 by itself, in the delivery part 340 to which the convex part 360 is attached, the base part 361 of the convex part 360 is added to increase the height of the push-up part 350. In addition, since the inner peripheral side of the delivery portion 340 is also raised by the extending portion 362 of the convex portion 360, even if the rotation of the tilted rotor 300 is extremely slow, the drug 5 will be ejected from the tilted rotor 300 with a high probability. It is pushed up and transferred to the annular rotating body 200 .

In addition, since the parallel wave-like unevenness 321 is formed in the relatively flat central portion 320 of the upper surface of the inclined rotor 300 , the drug 5 on the upper central portion 320 is When the shaft rotates, the direction of action of the frictional force of the parallel wave-shaped unevenness 321 also changes under the condition that the relative direction of action of gravity changes. They slide one after another from the top central portion 320 to the delivery portion 340 . Furthermore, since parallel wave-shaped unevenness similar to the parallel wave-shaped unevenness 321 is also formed in the delivery section 340, the drug 5 in the delivery section 340 is pushed up by the push-up section 350 as long as it is lumped. Since most of them collapse quickly, when the medicines 5 transfer from the tilted rotor 300 to the upper peripheral edge portion 230 of the ring-shaped rotor 200, the number of medicines 5, 5 in a state in which a plurality of medicines 5, 5 are vertically overlapped is considerably reduced.

If the drug 5 on the upper end peripheral edge 230 of the annular rotor 200 (see FIG. 2(a)) is easy to roll, it rolls and reaches the groove 231, where it stabilizes at a wide groove width (see FIG. 2(a)). 2(b), see FIG. 3), even if it is difficult to roll, it is stabilized at the groove 231 by light interference, and is sorted in order by the circular motion of the upper end peripheral portion 230 forming the drug transport path (see FIG. 5(a)). Below the front hanging object 612 of the first sorting member 610 of the mechanism 600, the inner peripheral side of the first restricting member 710 of the restricting mechanism 700, the second restricting member 720 of the restricting mechanism 700, and the second sorting member of the sorting mechanism 600 620 middle hanging object 622; It is conveyed to the exit 14. In addition, since the upper peripheral edge portion 230 is inclined at an angle β in a direction to raise the position of the drop discharge port 14 during transportation (see FIG. 2(c)), the component force of gravity pushes the drug 5. Although it tries to return, the component force is minute and does not reach the propulsive force due to the interference of the grooves 231 at all.

The transport situation will be described in detail step by step. First, when the medicine 5 comes under the front hanging object 612 of the sorting mechanism 600 (see FIGS. 5(a) and (b)), the single medicine positioned substantially in the center of the medicine conveying path of the upper edge portion 230 5, whether it is flat or spherical, is smoothly transported without interfering with the front hanging object 612, but the medicine 5 that rides on or leans against the front hanging object 612 Since it interferes with the lower part of the Moreover, the interfering drug 5 is either pushed between the two front hanging members 612, that is, to the center of the drug transport path, or is pushed inward from the drug transport path and returned to the inclined rotating body 300. It is often divided into Moreover, since the interference at that time is such that the front hanging object 612 is easily deformed and escapes, even if the medicine 5 is fragile, it is difficult to break.
In this manner, at the front hanging object 612, the height of the medicine 5 is moderately regulated, and the distribution in the width direction is moderately performed depending on the situation.

Next, when the medicine 5 comes to the side of the first restricting member 710 of the restricting mechanism 700 (see FIG. 5(a)), the inner peripheral side surface of the first restricting member 710 has a lower portion 711 that has a width restricting function. (see FIG. 4(c)), the medicines 5, 5 arranged side by side on the inner peripheral side are thereby pushed out from the medicine conveying path toward the inclined rotating body 300, or the medicine conveying They are rearranged back and forth on the route. In addition, since an upper stage portion 712 that has a height regulating function is also formed on the inner peripheral side surface of the first regulating member 710 (see FIG. 4(c)), an object riding on or leaning on another medicine 5 can be prevented. If the drug 5 is not in contact with the overhang of the upper stage portion 712 or the inclined surface below it, it is possible to prevent the medicines 5 from riding on each other. Since the running-on or the like has already been eliminated to some extent by the first sorting member 610, it is almost eliminated by further elimination.

Then, when the medicine 5 comes between the second regulating member 720 of the regulation mechanism 700 and the middle hanging object 622 of the sorting mechanism 600 (see FIG. 5(a)), the single medicine 5 is slightly separated from the middle hanging object 622. However, since the interference with the middle hanging object 622 is weak, it is conveyed without being hindered in its progress. On the other hand, medicines 5 riding on or leaning on other medicines 5 interfere more strongly with the intermediate hanging object 622 than when the medicines 5 are singular, so that riding on them is often eliminated. . Interference at this time is also such that the middle hanging object 622 deforms and escapes more easily than the front hanging object 612, so even if the medicine 5 is fragile, it does not easily break. Further, the interfering medicine 5 is pushed inward from the medicine conveying path and returned onto the inclined rotating body 300, or moved toward the second sorting member 620 and stays on the medicine conveying path.

Furthermore, when the drug 5 comes between the second regulating member 720 of the regulating mechanism 700 and the trailing hanging object 632 of the sorting mechanism 600 (see FIG. 5(a)), the drug 5 overlapping vertically or side by side Although most of the medicine 5 that is present is already gone, it is possible that there is some medicine 5 that stays on the medicine conveying path but is too close to the inner peripheral side. , and is moved toward the second sorting member 620 while continuing to stay on the drug transport path. Interference with the trailing hanging object 632 is weak and gentle because the small ball 633 is small, but it is tenacious because of the attraction force of the attracting member 640 . Moreover, even when the trailing hanging object 632 sways, the swaying is suppressed by the attracting force of the attracting member 640 and immediately settled.

When the drug 5 comes to the side of the rear end of the second regulating member 720 of the regulating mechanism 700 (see FIG. 5(a)), the same procedure as described above for when the drug 5 comes to the side of the first regulating member 710 is performed. Then, the final drug alignment process is performed by the width regulating function of the lower part 721 and the height regulating function of the upper part 722 , and the drugs 5 are arranged in a line on the drug transport path of the upper edge portion 230 .
Thus, in the medicine feeder 100, the front hanging object 612, the first regulating member 710, the middle hanging object 622, the rear hanging object 632, and the second regulating member 720 regulate the height or width of the medicine. Although there is a difference as to which is the primary and which is secondary, most of them regulate both. Both restrictions, which are repeated in stages, line up on the drug delivery path.

Then, when the drug 5 comes to the outer peripheral side of the ejection guide 13 (see FIG. 5A), the drug 5 falls along the outer peripheral side of the ejection guide 13 as the annular rotating body 200 rotates to the ejection port 14. sent in. At that time, many medicines such as disk-shaped drugs move on the upper end peripheral part 230 while maintaining a stable state due to friction with the upper end peripheral part 230, so they enter the drop discharge port 14 one by one. On the other hand, the drug that rolls easily, such as a ball, is pushed by the discharge guide 13 and flows from the widened portion of the groove 231 of the upper end peripheral portion 230 of the annular rotating body 200 to the chamfer 232 of the upper end peripheral portion 230 via the tip side of the groove 231 . Although it moves (see FIGS. 2(b) and 3), the timing of movement from the groove 231 to the chamfer 232 is stabilized by the inclination (β) of the upper edge portion 230 (see FIG. 2(c)), Since the subsequent movement toward the drop outlet 14 is rapid and stable due to the inclination (α-β) of the chamfer 232, even the drug that easily rolls enters the drop outlet 14 one by one.

Then, the drug 5 that has entered the drop discharge port 14 falls down the drop path in a substantially free-falling state (see FIG. 8A), and passes through the detection destination of the drug drop detection means 560 . When the estimated value of the drug size is cleared, that is, when the drug 5 is the first discharged drug, the drug size is estimated according to the detection time length for detecting the passage time at that time, and furthermore, the estimated value is Based on this, the rotation speed of the rotary drive motor 540 and thus the rotation speed of the rotary containers 200+300 are set. Specifically, the speed setting is automatically performed so that the rotation container 200+300 is rotated at a high speed when the estimated value of the drug size is large, and the rotation container 200+300 is rotated at a low speed when the estimated value of the drug size is small. , the rotating container 200+300 rotates at the set speed. As a result, the speed of small medicines can be reduced to prevent unwanted multiple drops, and the speed of large medicines can be increased to improve efficiency.

Furthermore, every time the drop of medicine is detected by the medicine drop detection means 560, the controller 570 notifies the medicine discharge operation control program to the medicine quantity management program that one medicine has been discharged. Then, when it is confirmed by the drug number management program that the number of drug discharges has reached the indicated value of the drug discharge instruction, the drug number management program issues a command to stop the discharge operation to the drug discharge operation control program. Since the operation of the rotation drive motor 540 is stopped under the control of the ejection operation control program, the medicine ejection operation stops.
In this way, the number of medicines 5 instructed by the medicine discharge instruction is fed from the medicine feeder 100, and the medicine supply corresponding to one medicine discharge instruction is quickly and accurately completed.

Although omitted in the above explanation of the operation to avoid complication, the container extension body 800 is attached to the medicine feeder 100 (see the left back part in FIG. 7(a)), and the annular rotating body 200 is mounted thereon. A description is added of the operation when the drug 5 is injected to a height exceeding .
In this case, from the position immediately behind the position where the drug 5 is transferred from the inclined rotor 300 to the annular rotor 200 to the front of the discharge guide 13 (see FIG. 5A), the upper end peripheral edge portion 230 of the annular rotor 200 is Since the upper drug transport path and the upper space of the inclined rotating body 300 are partitioned by the hanging portion 830 of the container extending body 800 (see FIG. 6A), the drug in the cylindrical portion 820 of the container extending body 800 The drug 5 does not undesirably avalanche, and the drug 5 passes through the bulge 812 of the through hole 811 (see FIG. 6(b)) and little by little gets on the drug transport path.

Similarly, when the container extending body 800 is attached to the drug feeder 100, the sorting mechanism 600 and the regulating mechanism 700 return the container from the drug conveying path above the upper end peripheral edge portion 230 of the annular rotating body 200 to above the inclined rotating body 300. The drug 5 (see FIG. 5(a)) is accommodated in the gap between the inner peripheral wall surface of the annular rotating body 200 (see FIG. 2(a)) and the outer peripheral surface (see FIG. 6) of the drooping portion 830 of the container extending body 800. Then, it is returned to below the through hole 811 of the container extending body 800 by the tilting rotating body 300 . Of the upper surface of the inclined rotating body 300, the peripheral edge portion 330 of the upper surface is formed with a transfer portion 340, a push-up portion 350, and even a convex portion 360. Even if it is in a situation where it dives below 5, it will be sent accurately.

In addition, the control method of the controller 570 will also be described. In addition to the discharge operation mode in which the rotary containers 200 and 300 are simultaneously driven forward and reverse, which is slightly different from the previously described discharge operation mode, the so-called one-sided sequential reverse discharge operation mode. When the latter sequential reverse discharge operation mode is selected, each time even one discharge of the drug 5 is detected, only the inclined rotor 300 is slightly reversely rotated. is done. As a result, the transport speed of the drug transport path on the upper end peripheral portion 230 of the annular rotating body 200 is not reduced, and the excessive discharge of the drug 5, which tends to roll easily, is accurately prevented. A stirring effect that cannot be obtained can also be exhibited by inversion. In particular, the convex portion 360 attached to the push-up portion 350 of the inclined rotating body 300 exerts a large stirring effect even when the rotation is reversed. Note that the ratio of reverse rotation to forward rotation is not limited to every time as described above, and can be appropriately selected such as one reverse rotation every two forward rotations, one reverse rotation every several forward rotations, or the like. It would be nice to be able to do it.

Furthermore, when the medicine handled by the medicine feeder 100 is changed, and if medicine still remains in the medicine feeder 100, the remaining medicine is collected. Two residual drug recovery means are provided.
The first is to continuously reverse the rotation container 200+300 for a sufficient time. Since it is pushed inside the ring-shaped rotating body 200 by the inner peripheral side extension surface of the discharge guide 13 or the like and gathered on the inclined rotating body 300, it is taken out by hand or the like.
The second method is to rotate the rotating container 200+300 continuously until the discharge is completed. Enclose in the packaging paper and collect.

Further, when the medicine handled by the medicine feeder 100 is changed, the mold medicine 5a must also be replaced. Since the small lid 741 of the mold storage space 740 is transparent, the presence or absence, shape, etc. of the mold medicine 5a placed there can be easily and reliably recognized by visual inspection, so that undesired forgetting to remove it is unlikely to occur. The same applies to the mold medicine 5a placed in the manual adjustment mechanism 650 of the sorting mechanism 600, since it is not sealed by the clamping method and can be visually observed.

[others]
In the above-described embodiment, the mold chemicals 5a selected from the chemicals 5 are placed in the manual adjustment mechanism 650 of the second sorting member 620 and the mold storage space 740 of the regulation mechanism 700. However, the mold chemicals 5a are selected from the chemicals 5. It is not limited to the one used, and a substitute product other than the drug may be used as long as the essential part dimensions are the same.

In the above embodiment, in the sorting mechanism 600, only the support member 621 of the second sorting member 620 is a straddle sorting member, and the support member 611 of the first sorting member 610 is not a straddle sorting member. This is not essential, and the sorting member may straddle up to the support member 611 of the first sorting member 610 .

In the above embodiment, it has been explained that there is a control and how to reverse the inclined rotor 300 slightly in order to prevent excessive rolling of the medicine, but the ratio of reverse rotation to forward rotation may be increased. Since the inclined rotating body 300 is formed with the protrusions 360, the inclined rotating body 300 can push up the drug 5 and transfer it to the annular rotating body 200 even when the rotating body 300 is reversed. By repeating alternately at an appropriate ratio, it is also possible to transfer the medicine 5 in the rotating containers 200+300 while stirring them firmly.

In the above-described embodiment, the photosensor incorporated in the shaft support of the rotation shaft portion 370 of the tilted rotor 300 is illustrated as the tilted rotor mounting detection means 550. Any other sensor, such as a mechanical switch, may be used as long as it can detect the mounted tilting rotor 300 . The position at which the tilted rotating body mounting detecting means 550 is mounted is not limited to the shaft supporting portion of the rotating shaft portion 370. It may be an intermediate position of 542 or the like. The detection method is not limited to directly detecting the rotating shaft portion 370, and it may be detected indirectly via an appropriate link member or the like.

In FIG. 8A according to the above embodiment, the rotary drive motors 541 and 532 are shown smaller than the rotary drive members 511 and 512, but the rotary drive motors 541 and 532 may be larger and the rotary drive members 511 and 512 may be smaller. Also, while the rotary drive motor 541 and the rotary drive member 511 are not inclined, the rotary drive motor 542 and the rotary drive member 512 are inclined. Further, the lateral positions of the rotary drive motor 541 and the rotary drive member 511 and the lateral positions of the rotary drive motor 542 and the rotary drive member 512 are also optional design items.

The drug feeder of the present invention may be used to replace some or all of the multiple aligning disk rotation type drug feeders mounted on the tablet packaging machine, and only one or a few drug feeders are mounted. It may be installed in a tablet divider, or may be installed in a tablet counter (medicine counter) or the like that counts the number of medicines that are sequentially delivered in a device that fills medicine bottles with medicines such as tablets.
