Description

The present invention relates to a drug feeder that automatically feeds granular solid drugs such as tablets and ampoules in order to automate dispensing in hospitals, pharmacies, etc. Regarding the drug feeder that randomly accommodates drugs and sequentially delivers and sequentially discharges the drugs one by one by arranging them with a rotating body, for more details, we have strengthened the height regulation function when arranging drugs. Regarding.

[Background technology 1] (See Patent Document 1)
As an alignment feeding type drug feeder that transports tablets, etc. (drugs) of the same shape while aligning them in a line, it has an outer annular rotating body that can rotate around a vertical line, and a rotating body that rotates around an inclined line that is tilted from the vertical line. a tilted rotor that is rotatably installed inside the annular rotor and closes a hollow space of the annular rotor; A drug feeder has been put into practical use that includes a regulating member that aligns the separated solid drugs when the annular rotating body rotates.

Parts that are useful for understanding the structure and problems of the present invention will be specifically explained with reference to the drawings (see FIG. 6).
FIG. 6 shows almost the entire structure of the drug feeder 10, with (a) being a plan view and (b) being a longitudinal sectional front view.

The drug feeder 10 is of a double rotation type, and has a circumferential wall 11 located at the top of the housing and having a circular hollowed out central portion, and an upper end loosely fitted into the hollow circumferential wall 11. An annular rotating body 20 that is installed in a state where it is tilted or installed directly under the hollow of the peripheral wall 11, an inclined rotating body 30 that is installed in the hollow of this annular rotating body 20, and an inclined rotating body 30 inside this A support mechanism 40 that rotatably supports the annular rotating body 20 on the outside thereof, a rotary drive mechanism 50 that is 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.

Furthermore, the support mechanism 40 maintains the annular rotating body 20 in a state where it can rotate around a vertical line, and the tilted rotating body 30 in a state where it can rotate around an inclined line that is inclined from the vertical. The inner inclined rotating body 30 and the outer annular rotating body 20 maintain a small gap that does not allow the medicine to pass through but allows rotation, so that the inclined rotating body 30 closes the hollow of the annular rotating body 20. This constitutes the rotating container 20+30 of the double rotation type drug feeder, and the drug is transferred from above the peripheral edge 33 of the inclined rotating body 30 to the annular rotating body by lifting by the rotation of the inclined rotating body 30 and sorting by the sorting member 60. The drugs on the upper end periphery 23 are carried onto the upper end periphery 23 of 20 and transported to the drop discharge port 14 while being aligned by the horizontal transport by the rotation of the annular rotating body 20 and the alignment function of the regulating mechanism 70. It has become. Each part will be explained below.

The annular rotating body 20 consists of a lower part 21 whose hollow diameter is larger toward the upper side, and an upper part 22 whose hollow diameter is smaller toward the upper side.After the inclined rotary body 30 is housed in these hollows, both parts 21 and 22 are connected with bolts, etc. They are integrated by being connected with each other, and together with the tilting rotary body 30, they form a rotary container 20+30.
The top surface of the tilted rotating body 30 serves as the inner bottom of the rotating container 20+30, and in the illustrated example, a central protrusion 31 is formed at the center of a central portion 32 of the top surface. In addition, the upper surface of the peripheral edge 33 of the tilted rotating body 30 is processed into a gentle sawtooth waveform that is useful for scooping up the medicine over one circumference, and the scooped up medicine is smoothly rotated in an annular manner by rolling due to the tilt. It is in a downwardly downward state so that it can be fed into the upper peripheral edge 23 of the body 20.

The support mechanism 40 is composed of a plurality of members 41 to 43 distributed at various locations, including several passive members 41 mainly composed of radial bearings, and an annular body such as a hard rubber O-ring. - Contains rotational transmission members 42 and 43 made of annular bodies.
The rotation drive mechanism 50 includes a rotation drive member 51 disposed below the rotation container 20+30, and a rotation drive motor 54 that rotates the rotation drive member 51. The annular rotating body 20 is rotated around its axis at a relatively high speed by frictional transmission via the rotor, and the tilted rotating body 30 is rotated around its axis at a relatively low speed.

The sorting member 60 is mainly composed of an elongated bar extending from the base end 61 of the swinging fulcrum to the tip end 62 of the swinging end. 20, and the distal end portion 62 can swing up and down about this point. The part near the tip 62 is slightly bent, and in the normal state, the tip 62 is placed diagonally downward and rests lightly on the peripheral edge 33 of the tilted rotating body 30 due to its own weight. Most of the medicine that has been carried along the peripheral edge 33 without sliding down to the upper peripheral edge 23 comes into contact with the tip 62 and is returned to the center 32 of the tilted rotating body 30 by the reaction force. However, if this is not done smoothly, the distal end 62 swings and escapes upward in order to avoid damage to the drug.

The regulation mechanism 70 includes a first regulation member 71 installed further ahead of the sorting member 60 with respect to the rotational direction of the upper end peripheral edge 23 of the annular rotating body 20, and a second regulation member 71 installed further ahead of the sorting member 60. A member 72, a link mechanism 73 connected to both the first regulating member 71 and the second regulating member 72 via a pin-shaped rotation-permitting shaft member, and a mold storage space 74 that can accommodate a sample drug. It is equipped with.
Both the first regulating member 71 and the second regulating member 72 have their pivoting centers located on the peripheral wall 11 side, and their pivoting ends located above the upper end peripheral portion 23 of the annular rotating body 20. The width of the drug transport path above the upper peripheral edge portion 23 is narrowed from the outer peripheral side.

In addition, both the first regulating member 71 and the second regulating member 72 can variably adjust the narrowing amount of the drug transport 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 direction movement, the amount of adjustment of the narrowing amount of the drug transport path width by the regulating members 71 and 72 is also linked. Furthermore, when the sample drug is stored 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 is stopped by bringing the tip into contact with the sample drug. Both the swinging end portion of the first regulating member 71 and the swinging end portion of the second regulating member 72 narrow the drug transport path width above the upper end peripheral portion 23 by the width of the drug transport path corresponding to the sample drug. ing.

In addition, at a further advance point from such a regulating mechanism 70, a fall discharge port 14 is formed in the peripheral wall 11 and passes through it vertically. 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. A conveyance surface guide 12 is formed at the distal end of the discharge guide 13 and extends downward from there and also extends to the tip, and the reaction of the medicine coming into contact with the discharge guide 13 causes an inclined rotating body This prevents the device from falling undesirably in the direction of 30.

Furthermore, although not shown, a controller that controls the operation of the rotary drive motor 54 and a power source that supplies operating power to the controller are also built into the same housing or provided outside the housing. Further, a photo sensor and the like for detecting the falling medicine at the drop outlet 14 is also attached, and the detection signal is sent to the controller and the tablet counter.
The rotation control of the controller starts from low-speed rotation, and after detecting the discharge of the first drug and further detects the discharge of a predetermined number of drugs, shifts to high-speed rotation. In addition, the remaining number is calculated from the total number of discharged medicines specified in advance and the number of discharged medicines, and when the remaining number reaches a predetermined number that has also been specified, the rotation speed is reduced, and after the completion of medicine discharge, it is possible to prevent undesired excessive drops. To prevent this, it is also designed to rotate in the opposite direction.

The operation of such medicine feeder 10 will also be explained. Before sequentially delivering a large number of drugs using the drug feeder 10, the work of regulating the width of the drug transport path and the random injection of drugs are completed.
In the work of regulating the width of the drug transport path, the worker selects an appropriate one from among a large number of drugs as a molding agent, stores it in the mold storage space 74, and then attaches it to one end of the link mechanism 73. This can be accomplished simply by adjusting the position of the link mechanism 73 so that the two abut against each other.

When this work is performed, both the first regulating member 71 and the second regulating member 72 swing in conjunction with the link mechanism 73, and their swinging ends cause the upper end peripheral portion 23 of the annular rotating body 20 to The width of the upper drug delivery path is narrowed at two locations to correspond to the diameter of the molding drug.
In addition, for random injection of drugs, the operator may literally inject a large number of drugs into the rotating containers 20+30 from the upper opening of the annular rotating body 20 at random.
Then, the randomly stored medicines that have been thrown in will naturally gather on the lower part of the upper surface of the tilting rotating body 30.

The automatic operation is now ready, so when the drug feeder 10 is operated in, for example, a simple continuous delivery mode, the rotary drive motor 54 rotates at an appropriate speed under the control of the controller. Then, the rotary drive member 51 rotates around its axis in response to this, and the rotational 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 is also transmitted to the inclined rotating body 30 by friction transmission, and the large-diameter exterior rotation transmission member 42 and the small-diameter exterior 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 rotary body 30 rotates, the medicine that has been on the peripheral edge 33 of the tilted rotary body 30 among the randomly stored medicines accumulated on the inner bottom of the rotating container 20+30 is moved by the circular movement of the sawtoothed peripheral edge 33. scooped up from a low position to a high position.
Most of the medicine carried to the point where the peripheral edge 33 is higher than the upper peripheral edge 23 of the annular rotating body 20 rises above the upper peripheral edge 23 by sliding or rolling due to the slope of the peripheral edge 33. Transfer to.

On the other hand, the medicine remaining on the peripheral edge 33 of the tilted rotary body 30 because the upper end peripheral edge 23 was clogged with other preceding medicines, or because it happened to not slide down or roll. Further axial rotation of the tilting rotary body 30 carries it to the tip 62 of the sorting member 60, where it abuts the tip 62, and is moved in the opposite direction to the upper peripheral edge 23 by the reaction of the abutment. Therefore, the central portion 32 of the tilted rotating body 30 slides down along the tilted surface.
In this way, the excess drug returns to the randomly stored drug, so that the drug delivery path above the upper peripheral edge 23 is narrowed down to some extent and the drug is sent at a frequency close to the appropriate amount.

Since the annular rotating body 20 is axially rotating at a higher speed than the inclined rotating body 30, the drug on the upper peripheral edge 23 will be rotated to some extent depending on the difference in rotational speed when transferred from the peripheral edge 33. They may come apart, but if the medicine is small, some may be arranged in a vertical line, while others may be lined up horizontally or diagonally. When these drugs are carried to the first regulating member 71 by the rotation of the axis of the annular rotating body 20, the drugs in one row pass through as they are, but the drugs in the horizontal row are caused by interference with the first regulating member 71. The medicine inside is pushed out from above the upper peripheral edge part 23 and falls onto the tilted rotating body 30, returning to the randomly stored medicine, so that the side-by-side arrangement is eliminated.

However, when there are many drugs arranged side by side, some drugs may slip around the tip of the first regulating member 71 due to pushing each other. In such a case, some of the drugs that have passed through the first regulating member 71 may remain in a diagonally horizontal arrangement. In any case, the drugs that have passed through the first regulating member 71 are then carried to the second regulating member 72 by the axial rotation of the annular rotating body 20 and are again forced to be aligned in the same way. Even if there remains, it is only a small amount and the degree remains only in a diagonal horizontal arrangement, so the horizontal arrangement can be quickly and sufficiently resolved by reintroducing the regulation.

In this way, the aligned drugs cleared the double regulation and aligned in a line are carried one after another to the discharge guide 13 by the circulation movement of the upper end peripheral portion 23 accompanying the rotation of the axis of the annular rotating body 20, and It comes into contact with the outer side surface of the discharge guide 13 that obliquely intersects with the drug transport path on the peripheral edge 23 .
Most of the aligned drugs immediately proceed along the abutting side surface of the discharge guide 13 and are fed into the falling discharge port 14 in a line.

However, depending on the contact situation, some of the aligned drugs may be slightly repelled toward the inner periphery, but even when such a situation occurs, the aligned drugs will not be pushed onto the annular rotating body 20. The transport surface guide 12 prevents the transport surface guide 12 from falling or being caught in the diagonally intersecting region between the upper end peripheral portion 23 and the discharge guide 13 .
In this way, all the arranged medicines are fed into the drop discharge port 14 in a single line without waste. Since the medicine sent into the falling discharge port 14 is accelerated by gravity and increases its falling speed, the separation distance between the preceding and following medicines increases, so a photo sensor or the like installed at a place where the separation distance is sufficient is used to detect the falling medicine. By detecting the drug, it is possible to accurately count the number of drugs.

This type of drug feeder is based on a double-rotation type drug feeder, that is, the rotating container is made into an inner and outer double container, and the upper end of the outer annular rotating body is moved from the inner tilted rotating body to the upper end of the outer annular rotating body by rotation of the inner and outer rotating containers. By conveying the solid medicine above the peripheral edge and aligning the solid medicine with the regulating member, not only is there no need to provide a fixed rectification guide in the rotating body, but also medicines of various shapes and sizes can be aligned. The scope of sharing is expanding.

In addition, in such a drug feeder, in order to align the solid drugs in a stable position in a line on the upper edge of the annular rotating body, two regulating mechanisms for regulating the width of the drugs are arranged in front and back. At the same time, a sorting member for regulating the height of the medicine is placed in front of the above-mentioned regulating mechanism, and the alignment function is properly exerted by these members. As mentioned above, in order to avoid chemical damage, the tip swings and escapes upward when the reaction force from the chemical is strong, so it cannot be said that height regulation will always be carried out reliably. However, since the height regulation by the sorting member is a pre-processing to reduce the burden of width regulation by the regulation mechanism, there is no practical disadvantage.

[Background technology 2] (See Patent Documents 2 and 3)
On the other hand, when the scope of common usage expands as mentioned above, there are not only differences in shape and size, but also drugs of different materials, such as drugs with brittle surfaces as well as hard drugs, and drugs with easy-to-roll shapes such as spherical and spindle shapes. There will also be an increasing demand for sharing such things.
In order to handle fragile drugs or drugs that roll easily, the so-called sorting member must be adjusted so that the contact between the drug and the sorting member is softened in order to avoid or suppress damage to the drug or excessive rolling. Subtlety and diversification are required.

However, such measures tend to weaken the height regulation function of the sorting member, so rather than simply making it more delicate, efforts should be made to maintain the height regulation function even if the contact between the drug and the sorting member is relaxed. What's more, it is desirable to take measures that can be strengthened.
Therefore, an additional technical challenge was to create a drug feeder that follows the dual rotation type drug feeder and maintains the height regulation function when arranging drugs, while the sorting member makes gentle contact with the drugs. .

In order to solve such technical problems, the outer annular rotating body is rotatable about a vertical line, and the annular rotating body is rotatable about an inclined line tilted from the vertical line. a tilted rotary body installed inside the annular rotary body to close the hollow space of the annular rotary body; A drug feeder comprising a sorting member and a regulating member that are aligned when the body rotates, the regulating member regulating the width of the drug on the upper peripheral edge of the annular rotating body. , the sorting member includes a hanging object that hangs above the upper peripheral edge of the annular rotating body and can be deformed when the lower end is pushed sideways, whereby the upper peripheral edge of the annular rotating body A drug feeder has been developed in which the height of the drug above the drug feeder is regulated, and the hanging object consists of a plurality of loosely connected spheres.

Parts that are useful for understanding the problems of the present invention will be specifically explained with reference to the drawings of a drug feeder 100 that is an improved version of the drug feeder 10 described above (see FIGS. 7 to 9).
FIG. 7 is a longitudinal sectional view showing the overall configuration of the drug feeder 100.

FIG. 8 shows the configuration of a regulating mechanism 700 that is an improved version of the previously described regulating mechanism 70, in which (a) is a plan view of the regulating mechanism 700 when the molding agent 5a is placed in the molding place 74, and (b) is a plan view of the regulating mechanism 700. are a plan view and an end view of the first regulating member 710.
FIG. 9 shows the configuration of a sorting mechanism 600 that is an improved version of the sorting mechanism 60 described above, in which (a) is an external perspective view of the sorting mechanism 600 and its installation location, and (b) is FIG. 6C is a front view of the first sorting member 610 of the sorting mechanism 600, and FIG.

The difference between the drug feeder 100 and the previously described drug feeder 10 (see FIG. 7) is that the rotational drive mechanism 50 includes two rotational drive motors 54a and 54b to rotate the annular rotating body 20 and the tilted rotating body 30. The rotation of the annular rotating body 20 can now be controlled individually, and the annular rotating body 20 has become a bowl-shaped unit that allows the tilting rotating body 30 to be inserted and removed without disassembling it vertically. Examples include the addition of a tilting rotating body attachment detecting means 55 for detecting the attachment and detachment of the drug, and the clear identification of a drug drop detecting means 56 below the drop discharge port 14.

Furthermore, the regulation mechanism 70 has been modified to become the regulation mechanism 700, and the sorting member 60 has been modified to become the sorting mechanism 600. The regulating mechanism 700 and sorting mechanism 600, which are closely related to each other, will be described in detail.

When the regulating mechanism 700 (see FIG. 8(a)) takes over the previously described regulating mechanism 70, the mold storage area 74 in which the mold chemical 5a is set and the link mechanism 73 that interlocks the regulating members 71 and 72 are generally kept as they are. However, the first regulating member 71 and the second regulating member 72 have been improved to become the first regulating member 710 and the second regulating member 720, respectively.
Since the first and second regulating members 710 and 720 have the same shape, only one 710 will be described in detail (see FIG. 8(b)). The left end swinging center is located on the peripheral wall 11 side, and in the figure, the right end swinging end is located above the upper end peripheral edge 23 of the annular rotating body 20, and the upper end peripheral edge moves forward and backward in the longitudinal direction of the link mechanism 73. It exhibits a width regulating function of narrowing the width of the drug transport path above the portion 23 from the outer circumferential side.

Moreover, the first regulating member 710 (see FIG. 8(b)) has a modified inner circumferential side surface, and the inner circumferential side surface follows the inner circumferential side surface of the first regulating member 71 described above. In addition to the lower part 711 that plays a width regulating function, an upper part 712, which was not present in the first regulating member 71 described above, is also formed. The upper portion 712 projects further inward than the lower portion 711, and there is an inclined surface between the upper portion 712 and the lower portion 711. Therefore, in the first regulating member 710, the lower part 711 performs a strict width regulation function according to the state of the link mechanism 73, and the upper part 712 performs gentle height regulation.
The same applies to the second regulating member 720, although a detailed explanation will be omitted.

The sorting mechanism 600 shown in FIG. 9 is a modified version of the previously described sorting member 60, and is a central part to which the present invention is applied.
9 shows the structure of the sorting mechanism 600 of the drug feeder 100, in which (a) is an external perspective view of the sorting mechanism 600 and its installation location, and (b) is a first sorting mechanism of the sorting mechanism 600. 6 is a front view of the member 610, and FIG. 6C is a front view of the second sorting member 620 of the sorting mechanism 600. FIG.

The sorting mechanism 600 (see FIG. 9(a)) is a first sorting member disposed upstream of the regulating mechanism 700 in the drug transport path of the upper end peripheral portion 230 of the annular rotating body 200, similar to the sorting member 60 described above. 610, and a second sorting member 620, which is disposed in a position parallel to the regulating mechanism 700 in the drug transport path, unlike the sorting member 60, and these plural members perform a sorting function in multiple stages. It has become something to do.
Both members 610 and 620 are attached to a plate body that includes the discharge guide 13 and supports the regulation mechanism 700, similarly to the sorting member 60 described above.

The first sorting member 610 (see FIGS. 9A and 9B) includes a short support member 611 whose vertical position can be adjusted using a manual screw mechanism, and a short support member 611 that is attached to a portion near the tip of the support member 611. It is provided with a front-stage hanging object 612 (first type hanging object) that moves up and down accordingly.
The front hanging object 612 (see FIG. 9(b)) is made up of a plurality of large balls 613 (two spheres in the figure) loosely connected to form a chain, and can be easily and easily constructed using a commercially available ball chain or the like. It can be realized at low cost. In the first sorting member 610, two front-stage hanging objects 612 hang side by side from the support member 611 above the drug transport path of the upper end peripheral portion 230, and normally the lower ends of the front-stage hanging objects 612 are slightly lower than the height of the medicine. The vertical position is adjusted so that the

The second sorting member 620 (see FIGS. 9(a) and 9(c)) includes a longer support member 621 whose vertical position can also be manually adjusted, and a longer support member 621 that is attached to a portion near the tip of the support member 621 to accompany the support member 621. The support member 621 includes a middle hanging object 622 and a rear hanging object 632 (both of which are first type hanging objects) 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. 9(c)) is made up of a plurality of medium beads 623 (three spheres in the figure) loosely connected to form a chain, but the medium beads 623 are small and the number of connected objects is reduced. 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) to form a chain, and the beads 633 are even smaller and the number of connected beads is increasing.

The manual adjustment mechanism 650 manually raises the support member 621 to widen the gap between it and the lower limit setting mechanism 651, and then places the molding agent 5b on the lower limit setting mechanism 651 (as shown in the figure placed in the mold storage space 74 described above). 8(a) is placed, and then manually lowered the support member 621 to a point where it lightly touches the molding agent 5b. The vertical position of 621 is arranged to correspond to the molding agent 5b.
A scale member 652 is attached to the lower limit setting mechanism 651 (see FIG. 9(c)), and the scale indicates the distance between the lower limit setting mechanism 651 and the support member 621 and the size of the molding agent 5b. The height regulated by the second sorting member 620 adjusted by the adjustment mechanism 650 is also shown. Further, since the measurement and display of the molding agent 5a are performed in conjunction with the vertical position adjustment of the support member 621, it also serves as a guide for adjusting the first sorting member 610.

Furthermore, the positional relationship, role sharing, etc. of the above-described front hanging object 612, middle hanging object 622, and rear hanging object 632 will be explained.
The two front hanging objects 612 both hang down above the drug transport path of the upper peripheral edge 230, but are lined up in the radial direction of the upper peripheral edge 230, which is the transverse direction of the drug transport path. The lower end position of the front hanging object 612 cannot be generalized because it depends on the adjustment policy, but in most cases, it is placed slightly lower than the drug so that if the drugs overlap on the drug delivery path, it will interfere with the drug above. be made expensive. Since the large balls 613 are heavy, the overlapping of the medicines is efficiently resolved, but since the large balls 613 at the lower end, which is the free end, escapes by deformation of the connecting portion directly above, there is less impact on the medicines.

In addition, when the drug is spherical, it tends to roll and its position is often unstable, but when the drug is located at a desirable location such as the center in the transverse direction of the drug delivery route, the drug is placed in a horizontally arranged front hanging object. Pass through between 612. In addition, when the drug is slightly shifted laterally from the center, the drug slightly interferes with the front hanging object 612 that is shifted from the center, and the drug is moved to the center (for drugs that easily roll, the upper end of the annular rotating body 200 described above). (at the widened portion of the groove 231 of the peripheral portion 230). On the other hand, when the drug is largely deviated from the center, some of the drug is moved to the center depending on how it hits, but most of the drug is pushed out from above the upper end peripheral portion 230 and returns to the top of the tilted rotating body 300.

The support members 621 of the two middle-stage hanging objects 622 are straddling sorting members that straddle the regulation mechanism 700, and both middle-stage hanging objects 622 hang above the drug transport path of the upper end peripheral portion 230, and the regulating mechanism 700 is straddled. It is located next to the mechanism 700 (particularly the second regulating member 720) and is a horizontally hanging object.
Further, both of the middle-stage hanging objects 622 are located above the drug transport path of the upper end peripheral portion 230, and are lined up diagonally with respect to the drug transport path.

Further, in a standard setting of the relationship between the support member 621 and the manual adjustment mechanism 650, the lower end position of the middle hanging object 622 is set slightly lower than the drug on the drug transport path.
Therefore, the middle hanging object 622 has the function of eliminating the overlapping of drugs by interfering with the drug on the upper drug if drugs overlap on the drug transport path, as well as eliminating the overlapping of the drugs, for example, when the middle hanging object 622 The drug alignment function on the drug delivery path is strengthened by determining whether drugs that happen to be placed on the inner circumference side of the drug delivery path in a side-by-side state are returned to the center of the drug delivery path or to the tilted rotating body 300. It also has the function of

Of the two rear hanging objects 632 (see FIG. 9(a)), one (the six-part object at the back in the figure) hangs above the inner circumferential side of the drug delivery path of the upper end peripheral portion 230, and the other (the one at the front in the figure) The seven-piece series) is removed from above the drug transport path of the upper end peripheral edge portion 230 and hangs down above the outer peripheral side of the tilted rotating body 300, and is lined up in the transverse direction of the drug transport path.
Moreover, as the height of the support member 621 is adjusted by the manual adjustment mechanism 650, the lower end position of one of the rear hanging objects 632 is made slightly lower than the lower end position of the above-mentioned middle hanging object 622, and the lower end of the other rear hanging object 632 is lowered. The position is set to be lowered further.
Therefore, the lower end positions of the first sorting member 610 in which large balls 613 are arranged in a row, the middle hanging object 622 in which medium balls 623 are arranged in a row, and the rear hanging object 632 in which small balls 633 are arranged in a row are arranged in the order of the size of the balls. ing.

Further (see FIG. 9(a)), at least the inner circumferential side of the rear hanging objects 632 (the seven-strand object in the front in the figure) uses a magnetic material such as iron as the material of the small beads 633. Correspondingly, an attracting member 640 made of a permanent magnet or the like is attached to a portion of the second regulating member 720 near the rear hanging object 632 by fitting or the like. Since the attractive force adds to the force of gravity, the rear hanging object 632 exerts a gentle but effective reaction force on the drug that comes into contact with it from above the drug delivery path. ing. As a result, the medicine that has been away 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 rear hanging object 632 emphasizes strengthening the width regulation of the medicine by the second regulating member 720 rather than its own medicine height regulation function.

In such a drug feeder, there is no need to provide a fixed rectifying guide in the rotating body, and the range of common use for drugs of various shapes and sizes has expanded (see Background Art 1, Patent Document 1). (See Background Art 2, Patent Documents 2 and 3), by assigning the latter-stage regulation mechanism that regulates the width of the drug to the height regulation function, and then relaxing the height regulation function of the sorting member located upstream. , from hard and durable drugs to brittle drugs, and from drugs that are difficult to roll such as plates to drugs that are easy to roll such as spheres and spindles, solid drugs can be easily aligned in a line on the drug transport path around the upper edge of the annular rotating body. It is now possible to do so.

However, when various drugs with different shapes and materials are used for a long time, in rare cases, so-called multi-layered drugs, in which multiple drugs are stacked one on top of the other, remain in a state that is difficult to unravel. It escapes the height regulation of the sorting member and reaches the subsequent regulation mechanism, and is not understood by the height regulation function of the regulation mechanism, and furthermore, due to the width regulation function of the regulation mechanism, the drug transport path of the annular rotating body is If a patient spends a long time being dropped onto one of the tilted rotors, this may trigger a large number of subsequent drugs to remain on the drug delivery path of the annular rotor. It has been found.

If such a situation that can be called a congestion situation occurs, the frequency of drug delivery from the regulating mechanism to the drop discharge port will decrease, and the sequential discharge function of drugs will be impaired more than expected, resulting in an undesirable reduction in processing capacity. Further, undesired time-out of drug discharge detection may lead to a false determination that all the drugs in the feeder have been discharged and the feeder is empty.
Therefore, a technical challenge is to restore the height regulating function of the sorting member to an appropriate level using a simple method and within a range that does not damage even fragile drugs.

The drug feeder of the present invention (solution means 1) is invented to solve these problems,
an outer annular rotating body that is rotatable about a vertical line; and an annular rotating body that is installed inside the annular rotating body so as to be rotatable about an inclined line that is inclined from the vertical line, and is provided inside the annular rotating body to open a hollow space of the annular rotating body. a tilting rotary body for blocking, and a sorting member and a regulating member that align solid medicines carried from above onto the upper end periphery of the annular rotary body by the rotation of the tilting rotary body when the annular rotary body rotates. The regulating member is configured to regulate the width of the drug on the upper peripheral edge of the annular rotating body, and the sorting member hangs above the upper peripheral edge of the annular rotating body. In the drug feeder, the height of the drug above the upper end peripheral portion of the annular rotating body is regulated by comprising a hanging object,
A first type of hanging object and a second type of hanging object having different shapes are provided as the hanging object, and the first type of hanging object can be deformed when its lower end is pushed sideways. The second type of hanging object is characterized in that its upper end is loosely supported and can swing without being deformed when its lower end is pushed sideways.
The above-mentioned vertical line is imaginary, and the vertical line mentioned above is typical, but it may be inclined from the vertical line as long as it does not impair the drug transfer function of the annular rotating body.

Further, the drug feeder of the present invention (solution means 2) is the drug feeder of the above-mentioned solution means 1, in which the first type of hanging object and the second type of hanging object are attached to the annular rotating body. It is characterized by having different positions in the circumferential direction.

Furthermore, the drug feeder of the present invention (solution 3) is the drug feeder of the solution means 1 and 2, in which the second type of hanging object has a portion including the whole or a part of the lower end. The straight line in the longitudinal direction of the lower end surface of this plate-shaped portion and the straight line in the circumferential direction of the upper end peripheral edge of the annular rotating body maintain a relationship of "straight line at the twisting position". The medicine is characterized in that the direction of transport of the drug that has been transferred by the annular rotating body and has come into contact with the second type of hanging object is directed toward the inner circumferential side of the annular rotating body.

Further, the drug feeder of the present invention (solution means 4) is the drug feeder of the above-mentioned solution means 1 to 3, in which the second type of hanging object is composed of a plurality of separable members arranged in parallel. characterized by something.

Further, the drug feeder of the present invention (solution means 5) is the drug feeder of the above-mentioned solution means 1 to 3, in which the second type of hanging object is a plurality of identical sheets arranged in parallel in a separable state. It is characterized by being made of shaped plate material.

In such a drug feeder of the present invention (Solution 1), as a hanging object to gently eliminate overlapping of drugs, the lower end is placed horizontally like the hanging objects 612, 622, and 632 described above. In addition to the first type of hanging object that can be deformed when pushed, there is also a second type of hanging object that is loosely supported at its upper end and can swing without deforming when its lower end is pushed sideways. , both are now used together. When any of the hanging objects comes into contact with the drug carried by the annular rotating body, it exerts a reaction force on the contacting drug to undo the overlap, but the means for generating the reaction force and the mode of action are deformed. Since the effect differs depending on the rocking motion, it is possible to expect a more diverse and higher overlap elimination effect than when the same mode of action is repeated. In addition, since the end that has come into contact with the medicine oscillates and escapes laterally, excessive reaction force is less likely to occur than when it escapes upward.
Therefore, according to the present invention, the height regulating function of the sorting member can be restored to an appropriate level within a range that does not damage even brittle drugs and in a simple manner.

In addition, in the drug feeder of the present invention (solution means 2), the first type of hanging objects and the second type of hanging objects are distributed in the circumferential direction of the annular rotating body, so that a plurality of hanging objects are provided. Not only can any object be placed on the drug delivery route without any difficulty, but by having multiple types of effects with different modes, that is, different types of ``releasing effects of superimposed drugs'' working at different times, both effects can be achieved. It is also possible to easily avoid undesirable situations such as canceling each other out.

Furthermore, in the drug feeder of the present invention (solution means 3), at least the lower end of the second type of hanging object is made into a plate shape, and the longitudinal direction of the lower end of this plate-shaped part is directed directly below the lower end. By using a simple method of tilting the drug with respect to the direction of drug transfer and limiting the range in which the inclination changes due to the swinging of the second type of hanging object, the drug can be placed on top of other drugs. The direction of transport of the transferred drug is changed to the inner circumferential side of the annular rotating body by contact with the second hanging object, so even with a simple configuration, the action of loosening the superimposed drug and returning the excess drug can be achieved. will be strengthened.

In addition, in the drug feeder of the present invention (Solution 4), by arranging a plurality of separable members in parallel to form a second type of hanging object, the plurality of members do not shift slightly when the drug comes into contact with them. Since the reaction force against the drug tends to decrease even if the total amount is the same, it is possible to strengthen the dissolving action of the superimposed drug while suppressing undesirable impact on the drug. can.

In addition, in the drug feeder of the present invention (solution 5), in addition to achieving the effects of solution 4 by arranging a plurality of separable members in parallel, the manufacturing burden is reduced by making the plate shapes the same. In addition, dense arrangement can be easily achieved by arranging multiple plates of the same shape side by side.

A specific form for implementing the drug feeder of the present invention will be described with reference to Example 1 below.
Embodiment 1 shown in FIGS. 1 to 5 embodies all of the above-mentioned solutions 1 to 5 (claims 1 to 5 originally filed).
In addition, for the sake of simplification, etc., when illustrating these figures, we omit the illustrations of those already described in the background art column or those for which equivalent products are sufficient, and focus on those necessary for explaining the invention or those related to it. Illustrated.
Further, for those that overlap with those described in the background art section, repeated explanations will be omitted, and the following will mainly explain the differences from the conventional technology.

The specific configuration of Example 1 of the drug feeder of the present invention will be described with reference to the drawings. FIG. 1 shows the structure of the main parts of the medicine feeder 1100, in which (a) is an external perspective view of the sorting mechanism 1600 and its surroundings, and (b) is an external perspective view of only the sorting mechanism 1600. 2 is a plan view, a front view, a right side view, a rear view, and a left side view of the single middle-stage hanging object 1623, and FIG. They are a plan view, a front view, a right side view, a rear view, and a left side view of the middle hanging objects 1622 arranged in parallel.

The drug feeder 1100 (see FIG. 1) follows the general structure of the previously described drug feeders 10 and 100 (see FIGS. 6 and 7) in a manner that maintains the required functions while appropriately improving the drug feeder 1100. (see FIG. 1(a)), a peripheral wall 1011 of the casing that follows the peripheral wall 11 of the casing already described, and an outer side that follows the annular rotating body 20 described above and is rotatable around a vertical line. An annular rotating body 1020 that follows the above-mentioned inclined rotating body 30 and is equipped inside the annular rotating body 1020 so as to be rotatable around an inclined line inclined from the above-mentioned vertical line. The tilting rotating body 1030 closes the hollow of 1020.

Further, the drug feeder 1100 (see FIG. 1(a)) carries the solid drug carried up from above the inclined rotating body 1030 onto the upper end peripheral portion 23 of the annular rotating body 1020 by the rotation of the inclined rotating body 1030 into an annular shape. It also includes a sorting mechanism 1600 and a regulating mechanism 1700 that align the rotating body 1020 when it rotates.
The latter regulation mechanism 1700 has been modified in some ways, including the ability to electrically adjust the width of the regulation target, but its basic structure is the same as that of the regulation mechanism 700 described above. In addition to regulating the width of the drug transport path above the upper peripheral edge 23 of the annular rotating body 1020, the final height of the drug is also controlled.

The sorting mechanism 1600 (see the scattered dot pattern part in FIG. 1(a) and FIG. 1(b)) does not set the height at which the drug above the upper end peripheral portion 23 of the annular rotating body 1020 can pass, but rather has a certain height. If so, this is to gently control leakage even if there is leakage, and as a hanging object that hangs down above the upper end peripheral portion 23 of the annular rotating body 1020, the large balls 613 are vertically connected and the bendable front stage hanging is used. It is equipped with three types of hanging objects: a middle hanging object 1622, which is made up of two plate-like middle hanging objects 1623 arranged side by side, and a bendable rear hanging object 632, which has small beads 633 arranged vertically. are doing. These 612, 1622, and 632 are arranged in that order from upstream to downstream of the upper end peripheral edge 23, and are all located above the upper end peripheral edge 23 (medicine transport path), but are not connected to the annular rotating body 1022. The positions in the circumferential direction are different.

The support member 1611 that suspends and holds the plurality of front-stage hanging objects 612 is short, whereas the support member 1621 that suspends and holds the middle-stage hanging objects 1622 and the rear-stage hanging objects 632 is long and straddles the regulating mechanism 1700. However, since both members 1611 and 1621 are made of one piece or are tightly connected, the first sorting member 1610 including the supporting member 1611 and the second sorting member 1620 including the supporting member 1621 are also integrated.
Therefore, although not shown in the drawings, the lower end positions of the three types of hanging objects 612, 1622, and 632 can be automatically adjusted up and down using an electric motor or the like. Moreover, when these three types of hanging objects are not needed, they can be removed all at once, making attachment and detachment easy.

In addition, as described above, the front hanging object 612 and the rear hanging object 632, in which the balls are connected in a bendable manner, allow the medicine conveyed by the upper peripheral edge 23 of the annular rotating body 1020 to reach the lower ends of these 612, 632. When it collides with an object and is pushed sideways, it becomes a type 2 hanging object, in which the object becomes arched overall and deforms more easily toward the lower end, in order to suppress the collision agent and soften the impact. It has become.

On the other hand, the middle hanging object 1623, which is a vertically elongated plate and is difficult to deform, has its upper end 1623a hooked loosely into the through hole 1621a of the support member 1621, so that it is loosely suspended. , it can be said to be a single, second-type hanging object that can swing without deforming when its lower end is pushed sideways.
Furthermore, the middle-stage hanging objects 1622, in which two (multiple) middle-stage hanging objects 1623 are arranged side by side in a dense but easy-to-separate state, can be said to be a second type of hanging objects in which a plurality of middle-stage hanging objects are arranged side by side. The object 612 and the downstream hanging object 632 are different from each other in the deformation state and the contents of the overlapping action of multiple drugs.

Furthermore, explaining the state in which the middle hanging object 1622 is held by the support member 1621 (see FIG. 1(b), FIG. 2, and FIG. 3), the swinging motion of the lower end is allowed to be relatively large in order to reduce the impact. However, regarding the so-called autorotation that revolves around an imaginary vertical axis, the oblique contact surface of the front lower end 1623c of the lower end 1623c of the two middle hanging objects 1623 that is the object of drug contact. In order to prevent the direction of 1623d from changing excessively when it is pressed by the abutting agent, the gap between the upper end 1623a of the middle hanging object 1623 and the through hole 1621a is appropriately suppressed, for example, in the form of a slit. The width of the oscillation caused by the above-mentioned autorotation can be suppressed to a small level.

A typical configuration example of the middle hanging object 1623 (see FIG. 2) includes a vertically long flat plate part 1623e, an upper end part 1623a that slightly protrudes from the upper end of the vertically long flat plate part 1623e, and an upper end part 1623a extending from the center of the vertically long flat plate part 1623e in the same direction as the upper end part 1623a. It has a central portion 1623b that protrudes from above, and a lower end portion 1623c that protrudes longer from the lower end of the vertically long flat plate portion 1623e. The vertically long flat plate portion 1623e, the upper end portion 1623a, and the center portion 1623b belong to one plane. On the other hand, the lower end portion 1623c protrudes toward the same side of both sides of the vertically long flat plate portion 1623d like the upper end portion 1623a and the center portion 1623b, but it is not in exactly the same direction and is tilted laterally by about 30 degrees. .

The middle hanging object 1622 (see FIG. 3) is made by overlapping two pieces of the middle hanging object 1623 described above, and with the upper end attached to the support member 1621, most of the two pieces overlap exactly. In this state, it hangs above the upper peripheral edge 23 of the annular rotating body 1020, and one of the lower ends 1623c of the two middle hanging objects 1623 becomes an oblique contact surface 1623d that receives the medicine 5. In the hanging state, a straight line that overlaps with the lower side of the oblique contact surface 1623d (a straight line in the longitudinal direction of the lower end surface of the plate-shaped portion) and a straight line in the circumferential direction of the upper end peripheral portion 23 of the annular rotating body 1020 are When viewed from the side, they appear to intersect, but when viewed from the side, they appear to be separated, maintaining a ``straight line at the twist position'' relationship.

The usage and operation of the drug feeder 1100 of Example 1 will be explained with reference to the drawings. FIG. 4 shows the operating state of the drug feeder 1100, especially the operating state of the sorting mechanism 1600, in which (a) shows the sorting of the drugs 5b and 5c that have arrived at the middle hanging object 1622 among the drugs 5. FIG. 3B is an external perspective view of the sorting mechanism 1600 and the like, and FIG. Moreover, FIG. 5 shows the swinging state of the middle hanging object 1622 that sorts the medicines 5b and 5c, and FIG. 5(a) is a plan view and FIG. 5(b) is a front view.

Before using the drug feeder 1100, it is necessary to adjust the height of the sorting mechanism 1600 according to the thickness of the drug 5, etc. (see FIG. 4). The first and second sorting members 1610 and 1620 are raised and lowered so that the lower end of the middle hanging object 1622 is higher than the height of , but lower than the height of 5 two medicines.
The vertical adjustment is performed by automatic control using an electric motor (not shown) or the like based on the thickness measurement value of the drug 5 that is set in advance in a controller (not shown) or a superordinate management device (not shown). In addition, if the drug is handled for the first time, the thickness measurement and data setting of the drug 5 should also be completed first.

Then, a large number of medicines 5, the required number or more, are put into the medicine feeder 1100, specifically onto the tilted rotary body 1030 surrounded by the annular rotary body 1020, and then the medicine feeder 1100 is When activated, the medicines 5 are lifted one after another by the tilting rotary body 1030 and placed on the upper edge portion 23 (drug transport path) of the annular rotary body 1020 (see FIG. 4(a)), and the annular rotation As the body 1020 rotates, the front hanging object 612, the middle hanging object 1623, and the rear hanging object 632 try to pass under them in this order.

At this time, the medicine 5 that is placed alone on the upper edge 23 without overlapping hardly interferes with the hanging objects 612 and 632 in front and behind, and even if it does interfere, it will only move slightly on the upper edge 23. , and passes under the intermediate hanging object 1623 without interfering with it at all.
On the other hand, for the drugs 5b and 5c stacked one above the other (see FIG. 4(a)), the upper drug 5b may come into contact with the front hanging object 612, and the overlapping may be broken by the reaction force. The front hanging object 612, which can deform when the lower end is pushed sideways, has a weak contact so as not to damage the drug 5, so the overlap may remain intact.

Then, when the drugs 5b and 5c that have passed through the front hanging object 612 while stacked vertically are brought to the middle hanging object 1622 (see FIG. 4), the upper drug 5b is transferred to the middle hanging object 1622. Because it comes into contact with the diagonal contact surface 1623d of the lower end 1623c and is prevented from moving straight forward due to the reaction force, the and move.
In this way, since the traveling direction of the upper drug 5b is directed toward the inner circumferential side of the annular rotating body 1020, the upper drug 5b advances inward from the upper end peripheral portion 23 of the annular rotating body 1020, and the upper drug 5b is directed toward the inner peripheral side of the annular rotating body 1020. They often fall upward (see the dashed line in Figure 4(b)).

The lower medicine 5b often passes under the middle hanging object 1622, but it may fall from the upper end peripheral edge 23 of the annular rotating body 1020 along with the medicine 5c.
The middle hanging object 1622 does not deform even if its lower end is pushed sideways, so it has a better ability to break up the overlap between the drugs 5b and 5c than the other hanging objects 612 and 632. However, in order not to damage the drugs, Since the shock at the time of contact with the drug and the subsequent pressure are alleviated by swinging, in rare cases, the drugs 5b and 5c may push aside the middle hanging object 1622 while still being overlapped. .

In that case, a gentle overlapping action is performed by the rear hanging object 632, and only if the medicines 5b and 5c do not collapse, the rear regulating mechanism 700 described above gently regulates the height of the overlapping medicines 5b and 5c. In addition, the width restriction that narrows the width of the drug transport path of the upper end peripheral edge portion 23 of the annular rotating body 1020 from the outer peripheral side also works.
Therefore, the overlapping of the drugs 5b and 5c is eliminated, or the drugs 5b and 5c are forcibly moved from above the upper end peripheral portion 23 of the annular rotating body 1020 to above the inclined rotating body 1030 while remaining overlapped, so that the overlapping of the drugs is eliminated. is not sent from the drug transport path to the drop outlet 14.

Furthermore, to explain the operation of a pair of middle-stage hanging objects 1622 formed by closely arranging two middle-stage hanging objects 1623 (see FIG. 5), the traveling direction of the overlapping of drugs 5b and 5c by the annular rotating body 1020 (two points In detail, the oblique contact surface 1623d (contact surface and first half copying surface) of the middle hanging object 1622 is inclined at an angle of θ1. On the other hand, the vertically long flat plate portion 1623e (second half tracing surface) of the middle hanging object 1622 is tilted only at the angle θ2, and since the angle θ1 is larger than the angle θ2 (θ1>θ2), the drug that has come into contact with the middle hanging object 1622 With respect to the overlap between 5b and 5c, a strong breaking force is applied in the first half, and in the second half, the force to expel the drug 5b from above the annular rotating body 1020 onto the inclined rotating body 1030 is strengthened, so that the overlap of the drugs is reduced. The rate at which the drug disappears from the drug delivery route increases.

Moreover, although the plurality of middle-stage hanging objects 1623, 1623 forming the middle-stage hanging object 1622 are in close contact with each other in the free state (see FIGS. 1(b) and 3), they can be separated. When the drug 5b comes into contact with the diagonal contact surface 1623d (see FIG. 5), the upper end 1623a hardly moves and the lower end 1623c (1623d) swings, and at the same time there is slight sliding or separation. Since this is also repeated, the impact at the time of contact and the subsequent frictional force are also reduced and alleviated.
In this way, the overlap between the drugs 5b and 5c can be easily eliminated with high accuracy.

It may be mounted on a tablet splitter, or furthermore, it may be mounted on a tablet counter (drug counter) that counts the number of medicines sequentially delivered in a device that fills medicines such as tablets into medicine bottles.
