Description

Technical Field

[0001] The present invention relates to a tablet dispensing device. Background Art

[0002] In a known tablet dispensing device, a large number of tablets are received, a rotating member is rotated to guide the tablets to a tablet guide path of the rotating member, and tablets below a partition member are discharged from a tablet outlet. In this tablet dispensing device, there is a problem that when the number of tablets decreases, the tablets placed on the rotating member do not enter the tablet guide path but rotate together with the rotating member, and thus always remain on the rotating member and cannot be discharged.

[0003] In the tablet cassettes disclosed in Patent Documents 1 and 2, an endless belt is provided above a partitioning portion (partitioning member), and tablets retained on a rotating member come into contact with the endless belt, thereby causing the tablets to fall into a compartment (tablet guide path).

[0004] However, the endless belts of Patent Documents 1 and 2 are made of round rope-shaped rubber, which interfere with the tablets in a state where both ends are supported and stretched in a straight line. Therefore, when the tablets retained on the rotating member approach the endless belt, they are pushed toward the center of the rotating member by the endless belt and sometimes cannot be guided to the tablet guide path. In addition, since the endless belt is always located in the tablet container, it becomes an obstacle that hinders the movement of the tablets moving together with the rotating member when there are many tablets.

[0005] In the tablet dispensing devices of Patent Documents 1 and 2, especially when the tablet is a half tablet, sometimes the corner of the half tablet is stuck in the circumferential groove at the intersection of the groove of the tablet guide passage and the circumferential groove for the partition member to enter, and it cannot be discharged.

[0006] In the tablet dispensing devices of Patent Documents 1 and 2, the accuracy of dividing a tablet into halves is poor, and the sizes of the two halves after the division are different. Therefore, sometimes a slightly smaller tablet in the tablet guide path will rotate in the tablet guide path and be sandwiched between the bottom surface of the tablet guide path and the inner surface of the tablet receiving portion to cause a bridge phenomenon (bridge), thereby hindering the rotation of the rotating part.

[0007] In a tablet dispensing device disclosed in Patent Document 3, the compartment (tablet guide passage) of the discharge disk (rotating member) is formed by a through hole with a circular cross section. When the tablet guide passage is a through hole with a circular cross section as in Patent Document 3, the tablets in the tablet guide passage will not interfere with the inner surface of the tablet receiving portion, but because the through hole is separated from the inner wall of the tablet receiving portion, there is a problem that the tablets are difficult to enter the tablet guide passage.

[0013] (Problems to be solved by the invention)

[0014] The present invention has been made in view of the above-mentioned problems in the prior art, and an object of the present invention is to provide a tablet dispensing device that can reliably guide tablets retained in a tablet storage portion to a tablet guide passage and discharge the tablets.

[0015] (Solutions to solve problems)

[0016] The following are measures taken to solve the above-mentioned problems.

[0017] (1) A tablet dispensing device, comprising: a tablet containing portion that contains tablets and is provided with a tablet outlet for discharging tablets; a rotating member that is arranged inside the tablet containing portion and is provided with a tablet guiding portion that guides the tablets toward the tablet outlet; the tablet dispensing device is provided with a tablet introducing component that guides the tablets retained in the tablet containing portion toward the tablet guiding portion.

[0018] According to the above configuration (1), the tablets accumulated in the tablet containing portion move together with the rotating member, come into contact with the tablet introducing member, are gathered by the tablet introducing member, and are guided to the tablet guiding portion.

[0019] (2) In the above-mentioned aspect (1), the tablet introduction member is a rod-shaped body that protrudes from the tablet containing portion side toward the rotating element.

[0020] According to the above configuration (2), when the tablet retained on the rotating member contacts the tablet introducing member, the tablet introducing member is appropriately bent, so that the impact is mitigated, thereby preventing the tablet from being damaged or broken.

[0021] (3) In the above-mentioned aspect (2), the rod-shaped body is formed into an S-shape when viewed from the side.

[0022] According to the above scheme (3), the stroke from the root of the rod-shaped body to the front end becomes longer, thereby reducing the reaction force received by the front end from the tablet, and through the forward and reverse movements of the rotating part, when the reaction force is applied to either side in the left or right direction when viewed from above, it will be subjected to the same deformation, thereby producing the same effect of introducing the tablet into the tablet guide part.

[0023] (4) In any one of the above-mentioned embodiments (1) to (3), when the rotating member is viewed from above, the front end of the tablet introduction member is separated from the tablet receiving portion by a distance smaller than the length of the tablet diameter relative to the inner surface of the tablet receiving portion.

[0024] According to the above configuration (4), the tablet that has come into contact with the inner surface of the tablet containing portion reliably comes into contact with the tablet introducing member and is guided to the tablet guiding portion.

[0025] (5) In the above aspect (4), in a plan view of the rotor, the front end of the tablet introduction member is located radially outward of the rotor relative to the center of the tablet guide portion.

[0026] According to the above configuration (5), the tablet in contact with the inner surface of the tablet containing portion reliably contacts the front end of the tablet introducing member and is guided to the tablet guiding portion.

[0027] (6) In any one of the above (2) to (5), the tablet introduction member is composed of a plurality of rod-shaped bodies.

[0028] According to the above solution (6), the tablets retained on the rotating member have multiple opportunities to contact the tablet introduction member. Therefore, even a tablet that contacts the tablet introduction member for the first time but does not enter the tablet guide portion will contact the tablet introduction member next and be guided to the tablet guide portion.

[0029] (7) In the above embodiment (6), the interval between the plurality of rod-shaped bodies is equal to or greater than the tablet diameter.

[0030] According to the above configuration (7), the tablet is not placed on a plurality of rod-shaped bodies, and therefore the tablet reliably contacts the rod-shaped body and is guided to the tablet guide portion.

[0031] (8) In the above-mentioned configuration (6) or (7), the front ends of the plurality of rod-shaped bodies have different heights relative to the rotating member.

[0032] According to the above solution (8), even if a tablet is stuck at the entrance of the tablet guide, it can be dropped into the tablet guide by the rod-shaped body having a low front end height.

[0033] (9) In any one of the above aspects (6) to (8), one of the plurality of rod-shaped bodies enters an outer peripheral recess formed along the circumferential direction on the side surface of the rotating member.

[0034] According to the above configuration (9), even if the tablet is stuck inside the tablet guide portion, it can be guided downwardly of the tablet guide portion by the rod-shaped body whose front end enters the outer peripheral recess.

[0035] (10) In any one of the above aspects (1) to (9), the tablet introduction member is provided so as to be able to move forward or backward relative to the tablet storage portion.

[0036] According to the above solution (10), when the tablet storage capacity in the tablet storage section exceeds the specified amount, the tablets are easily introduced into the tablet guide section, so the tablet introduction member is moved backward. When the tablet storage capacity in the tablet storage section becomes less than the specified amount, the tablet introduction member is moved forward so that the tablets are reliably contacted with the tablet introduction member and guided to the tablet guide section, thereby preventing the tablets from being retained on the rotating member.

[0037] (11) A tablet dispensing device, comprising: a tablet containing portion that contains tablets and is provided with a tablet outlet for discharging tablets; a rotating member that is arranged inside the tablet containing portion and is provided with a tablet guiding portion that guides the tablets toward the tablet outlet; a partitioning member that separates the tablets in the tablet guiding portion into the tablet guiding portion with one tablet located below; the tablet dispensing device comprises a tablet introducing member that changes the posture of the tablets in the tablet guiding portion above the partitioning member.

[0038] According to the above configuration (11), the tablets that are clogged and accumulated in the tablet guide above the partition member are changed in position by the tablet introduction member and fall downwardly into the tablet guide, thereby preventing the tablets from accumulating in the tablet guide.

[0039] (12) In the above-mentioned aspect (11), the front end of the tablet introduction member enters into an outer peripheral recess formed along the circumferential direction on the side surface of the rotating member.

[0040] According to the above-mentioned solution (12), the front end of the tablet introduction member entering the outer peripheral recess can easily contact the tablet blocked and retained in the tablet guide, thereby reliably changing the posture of the tablet and guiding it downward in the tablet guide.

[0041] (13) A tablet dispensing device, comprising: a tablet containing portion which contains tablets and is provided with a tablet outlet for discharging tablets; a rotating member which is arranged inside the tablet containing portion and is provided with a tablet guiding portion which guides the tablets to the tablet outlet; and a partitioning member which separates the tablets in the tablet guiding portion so that one tablet passes through the tablet guiding portion and is discharged to the tablet outlet; in the tablet dispensing device, a circumferential groove for the partitioning member to enter is formed on the outer circumferential surface of the rotating member, and a chamfered portion is provided on the upper end portion of the tablet guiding portion which is below the circumferential groove.

[0042] According to the above configuration (13), when the tablet is a half tablet, the corner of the half tablet will not be caught on the upper end portion of the tablet guide portion below the circumferential groove in the tablet guide passage.

[0043] (14) A tablet dispensing device, comprising: a tablet containing portion for containing tablets and provided with a tablet outlet for discharging tablets; a rotating member, which is arranged inside the tablet containing portion and provided with a tablet guiding portion for guiding tablets to the tablet outlet; and a partitioning member, which separates the tablets in the tablet guiding portion so that one tablet passes through the tablet guiding portion and is discharged to the tablet outlet; in the tablet dispensing device, a circumferential groove for the partitioning member to enter is formed on the outer circumferential surface of the rotating member, and the width of the tablet guiding portion below the circumferential groove is greater than the width of the tablet guiding portion above the circumferential groove.

[0044] According to the above configuration (14), when the tablet is a half tablet, the corner of the half tablet will not be caught on the upper end portion of the tablet guide portion below the circumferential groove in the tablet guide passage.

[0045] (15) A tablet dispensing device, comprising: a tablet containing portion, which contains tablets and is provided with a tablet outlet for discharging tablets; a rotating member, which is arranged inside the tablet containing portion and is provided with a tablet guiding portion for guiding the tablets to the tablet outlet; in the tablet dispensing device, the tablet guiding portion is a groove having a circular cross-section in a direction perpendicular to the axial direction of the rotating member.

[0046] According to the above-mentioned aspect (15), in the tablet guiding passage, the tablets do not interfere with the inner surface of the tablet receiving portion to hinder the rotation of the rotating member, and thus the tablets can be reliably discharged.

[0047] (Effects of the Invention)

[0048] According to the invention of claims 1 to 12, the tablets accumulated in the tablet storage section can be reliably guided to the tablet guide path and discharged.

[0049] According to the invention of technical solution 13 or 14, when the tablet is a half tablet, the corner of the half tablet will not be caught on the circumferential groove in the tablet guiding passage, so that the tablet can be discharged smoothly.

[0050] According to the invention of claim 15, in the tablet guide passage, the tablets do not interfere with the inner surface of the tablet receiving portion to hinder the rotation of the rotating member, and the tablets can be reliably discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0074] <First embodiment>

[0075] Figure 1 to Figure 3 FIG. 1 shows a tablet dispensing device 1 according to a first embodiment of the present invention. The tablet dispensing device 1 is detachably mounted on a mounting portion (motor base) not shown in the figure, and can dispense tablets in a quantity corresponding to a prescription, such as Figure 3As shown, the tablet dispensing device 1 includes a tablet accommodating portion 2 , a rotor 3 , a partition member 4 , and a tablet introducing member 5 .

[0076] like Figure 1 As shown, the tablet storage part 2 is a rectangular container with an upper opening, and a bottomed cylindrical rotating member storage part 6 is provided below the tablet storage part 2. A cover 7 is rotatably provided on the upper edge of the tablet storage part 2 via a hinge, and the upper opening of the tablet storage part 2 can be opened or closed by the cover 7. The rotating member 3 is rotatably stored in the rotating member storage part 6. Figure 2 As shown, a tablet outlet 6a is formed on the rear bottom surface of the rotating member receiving portion 6. On the rear side surface of the rotating member receiving portion 6 and above the tablet outlet 6a, a lower slit 6b for inserting the partition member 4 and an upper slit 6c for inserting the tablet introduction member 5 are formed in a manner extending along the circumferential direction of the rotating member receiving portion 6.

[0077] like Figure 3 As shown in FIG. 1 , a rotating member driving shaft 8 extending along the axial direction of the rotating member housing portion 6 is rotatably provided on the bottom surface of the rotating member housing portion 6. An axial hole 8a for inserting the shaft portion 11c of the rotating member 3 and an engaging portion 8b for engaging with the rotating member 3 are formed at the upper end of the rotating member driving shaft 8. Figure 2 As shown, a rotating member gear 9 is installed at the lower end of the rotating member driving shaft 8. In addition, an intermediate gear 10 meshing with the rotating member gear 9 is installed on the bottom surface of the rotating member receiving portion 6. When the tablet receiving portion 2 is mounted on a mounting portion not shown, the intermediate gear 10 meshes with the motor gear of the mounting portion, whereby when the motor in the mounting portion is driven, the rotating member driving shaft 8 is rotated via the motor gear, the intermediate gear 10 and the rotating member gear 9.

[0078] like Figure 3 As shown, the rotating member 3 can be received in the rotating member receiving portion 6 from the upper opening of the tablet receiving portion 2. Figure 4 , Figure 5 As shown, the rotor 3 is composed of an upper rotor part 11 and a lower rotor part 12 .

[0079] The top surface of the upper rotor member 11 is formed in a conical shape, and a plurality of stepped portions 11a for tablet stirring are formed at three locations in the circumferential direction of the top surface. Figure 5As shown, a concave portion 11b is formed on the bottom surface of the upper rotating member 11 to fit with the convex portion 12a of the lower rotating member 12. In addition, a shaft portion 11c is provided at the center of the bottom surface of the upper rotating member 11 to protrude downward, and an axial hole 11d is formed around the shaft portion 11c to insert the rotating member drive shaft 8. Tablet guide portions 13a extending in the axial direction are formed on the outer peripheral surface of the upper rotating member 11 at positions divided into six equal parts in the circumferential direction. Fig.10 As shown in (c), the cross section of the tablet guide 13a in the direction perpendicular to the axial direction of the rotor 3 has a circular shape, and its imaginary circle Ca contacts the inner surface of the rotor housing 6. Fig.10 As shown in (d), the inner diameter of the tablet guide 13a is larger than the radius of the tablet and smaller than the diameter of the tablet, and is large enough to allow a half tablet to pass through with its chord direction facing the vertical direction. Figure 4 The tablet guide 13a is formed in a groove shape extending in the axial direction on the outer peripheral surface. The upper end of the tablet guide 13a opens on the conical top surface of the upper rotor component 11, and the lower end opens on the bottom surface of the upper rotor component 11.

[0080] The lower rotating member 12 is formed in an annular shape, and has a convex portion 12a formed on its top surface to fit into the concave portion 11b of the upper rotating member 11. The height of the convex portion 12a is greater than the depth of the concave portion 11b of the upper rotating member 11, so that when the upper rotating member 11 and the lower rotating member 12 are fitted together, Figure 8 As shown in the figure, a circumferential groove 14 is formed between the upper rotating member 11 and the lower rotating member 12. Tablet guides 13b extending in the axial direction are formed at positions divided into six equal parts in the circumferential direction on the outer circumferential surface of the lower rotating member 12. The tablet guide 13b of the lower rotating member 12 is configured to be formed in the same cross-sectional shape as the tablet guide 13a at the same position as the tablet guide 13a of the upper rotating member 11. A chamfered portion 13c is provided at the upper end of the tablet guide 13b of the lower rotating member 12, that is, at a position lower than the circumferential groove 14.

[0081] The upper rotating member 11 and the lower rotating member 12 are assembled into one body by fastening with screws in a state where the concave portion 11b of the upper rotating member 11 is engaged with the convex portion 12a of the lower rotating member 12 and the tablet guide portion 13a of the upper rotating member 11 is aligned with the tablet guide portion 13b of the lower rotating member 12. The tablet guide portion 13a and the tablet guide portion 13b form one tablet guide portion 13.

[0082] Rotating member 3 is Figure 4 The shaft portion 11c shown is inserted into Figure 3After the shaft hole 8a of the rotating member driving shaft 8 is opened, Figure 2 The fixing screw 8c shown is fixed, so it is impossible to clean the inside of the tablet storage part 2, especially the bottom thereof. If the fixing screw 8c is removed, it can be cleaned, but this is difficult for the user. Figure 5A 2 shows a structure in which the rotating member 3 can be attached to or detached from the inside of the tablet containing portion 2 .

[0083] Figure 5A In the embodiment, a pair of elastic pieces 16 having claws 16a at the front ends are formed at the lower ends of the shaft 11c of the rotating member 3. The lower portion of the shaft 11c and the distance between one surface of the pair of elastic pieces 16 and the other surface on the opposite side are formed to a predetermined width w smaller than the diameter of the shaft 11c, and the one surface and the other surface on the opposite side form a distance portion 16b across edges.

[0084] On the other hand, a sleeve 17 is housed inside the rotating member drive shaft 8 so as to be rotatable together with the rotating member drive shaft 8. An engaging groove 17a having a width w is formed at the upper end of the sleeve 17, which engages with the opposite side distance portion 16b of the shaft portion 11c. The upper portion of the inner surface of the sleeve 17 is reduced in diameter to form a step portion 17b, and the claws 16a of the pair of elastic pieces 16 engage with the step portion 17b from below. A loading and unloading pin 18 is inserted into the lower portion of the inner surface of the sleeve 17. The loading and unloading pin 18 is composed of a head 18a slidably fitted on the inner surface of the sleeve 17, and a foot 18b protruding downward from the bottom surface of the head 18a. A recess 18c is formed on the top surface of the head 18a. The inner peripheral surface of the recess 18c is formed by an inclined surface that is inclined toward the inner side as it goes downward, so that it abuts against the claws 16a of the pair of elastic pieces 16. The leg portion 18b is slidably received in a through hole 19 formed at the center of the fixing screw 8c.

[0085] When the rotating member 3 is accommodated in the tablet accommodating portion 2, Figure 5A As shown in (a), the claws 16a of the pair of elastic pieces 16 engage with the step 17b of the sleeve 17 of the rotating member drive shaft 8, thereby preventing it from falling off upward. In addition, the opposite side distance portion 16b of the shaft portion 11c engages with the engagement groove 17a of the sleeve 17, thereby transmitting the rotation of the rotating member drive shaft 8 to the shaft portion 11c of the rotating member 3.

[0086] When removing the rotating member 3 from the tablet storage section 2, a pin-shaped jig is inserted through the through hole 19 of the fixing screw 8c located at the bottom of the rotating member storage section 6, so that the attachment and removal pin 18 is pushed upward as shown by the arrow P. In this way, the claws 16a of the pair of elastic pieces 16 of the shaft portion 11c of the rotating member 3 are pressed by the inclined surface of the inner periphery of the recess 18c of the attachment and removal pin 18, and the rotating member 3 is removed. Figure 5BAs shown by the two-dot chain line in FIG. 1 , the pair of elastic pieces 16 are deformed in the direction of approaching each other. As a result, Figure 5B As shown in the figure, the claws 16a of the pair of elastic pieces 16 are disengaged from the stepped portion 17b of the sleeve 17, so that the rotating member 3 can be pulled up and taken out from the tablet receiving portion 2. Since the user can also perform this operation, the user can remove the rotating member 3 when necessary, wipe the dirt or medicine powder inside the tablet receiving portion 2, or remove the tablet fragments and clean it. In this way, the tablet receiving portion 2 can be cleaned, thereby preventing contamination (contami) caused by the accidental falling of medicine fragments.

[0087] When the rotating member 3 is returned to the tablet storage section 2, the shaft portion 11c of the rotating member 3 is inserted into the sleeve 17 from the shaft hole 8a of the rotating member driving shaft 8. The pair of elastic pieces 16 of the shaft portion 11c enter the sleeve 17 in a state of being deformed toward each other by the inner surface of the sleeve 17, and the claw portion 16a is engaged with the step portion 17b, thereby being installed so as not to be detached upward.

[0088] It should be noted that the pushing-up operation of the mounting and dismantling pin 18 can be performed manually, but when the tablet dispensing device 1 is set at a predetermined position of a dispensing table (not shown), the mounting and dismantling pin 18 can also be pushed up by a protrusion provided on the dispensing table.

[0089] like Figure 6 As shown in FIG. 1 , the partition member 4 is composed of an arc-shaped brush portion 4a, a support portion 4b supporting the brush portion 4a, and a mounting portion 4c for mounting the partition member 4 on the tablet storage portion 2. The brush portion 4a is configured as follows: Figure 8 As shown, the brush 4a is inserted into the lower cutout 6b of the rotor accommodating portion 6 and enters the circumferential groove 14 of the rotor 3, thereby separating the lowest tablet from the tablet above in the tablet guide 13. The brush 4a is a conventionally known component, and thus its detailed structure is omitted.

[0090] like Figure 6As shown, the tablet introduction component 5 is composed of a brush portion 5a, a supporting portion 5b supporting the brush portion 5a, and a mounting portion 5c for mounting the tablet introduction component 5 on the tablet storage portion 2. The brush portion 5a is composed of three rod-shaped bodies protruding toward the center of the rotating member 3. The rod-shaped body can be a member that has elasticity itself, or a member that has an elastic portion such as a spring at its root. The tablet introduction component 5 is inserted into the upper cutout 6c of the rotating member storage portion 6 and is located above the inclined top surface of the upper rotating member component 11. The other parts of the tablet introduction component 5 except the front end of the brush portion 5a are located outside the tablet storage portion 2. Regarding the number of rod-shaped bodies of the brush portion 5a, there are three in the embodiment, but it is not limited to this. It can be one, two, or four or more.

[0091] like Figure 7 As shown, it is preferred that the spacing between the front ends of the rod-shaped bodies of the plurality of brush portions 5a is greater than or equal to the diameter of the tablet. This is because if the spacing between the front ends of the rod-shaped bodies of the brush portions 5a is smaller than the diameter of the tablet, the tablet will be placed above the brush portion 5a and cannot be discharged. When looking down at the rotating member 3, the front end of the brush portion 5a is located at a position that is separated from the inner surface of the rotating member accommodating portion 6 of the tablet accommodating portion 2 by a distance that is smaller than the diameter of the tablet. That is, the radial distance S between the inner surface of the rotating member accommodating portion 6 and the front end of the brush portion 5a is smaller than the diameter of the tablet. In other words, when looking down at the rotating member 3, the front end of the brush portion 5a is located at a position that is radially closer to the outside of the rotating member 3 than the circle Cb passing through the center of the tablet guide portion 13.

[0092] Next, the operation of the tablet dispensing device 1 of the above-described embodiment, particularly the tablet introduction member 5, will be described.

[0093] exist Figure 8 In the process, a large number of half tablets contained in the tablet containing part 2 are stirred as the rotating member 3 rotates, and enter each tablet guide part 13 of the rotating member 3. When the tablet guide part 13 approaches the tablet outlet 6a as the rotating member 3 rotates, the tablets in the tablet guide part 13 are separated by the partition part 4 into the lowest tablet and the tablets above it. In this way, the tablets below the partition part 4 are discharged from the tablet outlet 6a and are discharged after passing through the mounting part not shown. Each time the tablet guide part 13 passes through the tablet outlet 6a, each tablet is discharged, thereby packaging and dispensing the tablets corresponding to the number of prescriptions.

[0094] When the number of remaining tablets in the tablet containing portion 2 decreases, in the prior art, the tablets placed on the rotor 3 rotate together with the rotor 3 and are retained on the rotor 3 and cannot be discharged.

[0095] In the tablet dispensing device 1 of the present embodiment, the tablet introducing member 5 is provided, and therefore the tablets retained on the rotating member 3 are reliably guided to the tablet guiding portion 13 by the tablet introducing member 5 .

[0096] Further details are as follows. Figure 7 As shown in (a), the tablet T that has not entered the tablet guide portion 13' and has been retained on the rotating member 3 moves to the downstream side of the rotating member's rotation direction together with the rotating member 3 and contacts the brush portion 5a of the tablet introduction member 5, and Figure 7 As shown in (b), the tablets T retained on the rotating member 3 are pushed or bounced by the brush portion 5a toward the upstream side in the rotating direction of the rotating member and gathered, and introduced into the tablet guide portion 13" which rotates next. In this way, the tablets T retained on the rotating member 3 are reliably introduced into the tablet guide portion 13 by the tablet introduction member 5 and discharged.

[0097] The brush portion 5 a of the tablet introduction member 5 is formed of a rod-shaped body. Therefore, when the tablet contacts the brush portion 5 a , the brush portion 5 a is appropriately bent to mitigate the impact, thereby preventing the tablet from being damaged or broken.

[0098] When looking down at the rotating member 3, the front end of the brush portion 5a of the tablet introduction component 5 is located at a distance less than the tablet diameter relative to the inner surface of the rotating member receiving portion 6. Therefore, the tablet in contact with the inner surface of the tablet receiving portion 2 reliably contacts the tablet introduction component 5 and is guided to the tablet guide portion 13.

[0099] In addition, when looking down at the rotating member 3, the front end of the brush portion 5a of the tablet introduction component 5 is located radially outward of the rotating member 3 relative to the center of the tablet guide portion 13. Therefore, the tablet contacting the inner surface of the tablet containing portion 2 reliably contacts the front end of the tablet introduction component 5 and is guided to the tablet guide portion 13.

[0100] The tablet introduction member 5 is composed of a plurality of (three in the embodiment) rod-shaped bodies, so the tablets retained on the rotating member 3 have multiple opportunities to contact the tablet introduction member 5, so that even a tablet that contacts the tablet introduction member 5 for the first time but does not enter the tablet guide 13 will contact the tablet introduction member 5 next and be guided to the tablet guide 13. The heights of the plurality of rod-shaped bodies may also be different from each other. Sometimes, there is a situation where even if a rod-shaped body of a certain height does not play a role in guiding the tablet to the tablet guide 13, a rod-shaped body of another height will play this role. Therefore, by making the heights of the plurality of rod-shaped bodies different, the probability of being able to guide the tablet to the tablet guide 13 is increased.

[0101] Since the intervals between the plurality of rod-shaped bodies of the tablet introduction member 5 are equal to or larger than the tablet diameter, the tablets are not placed on the plurality of rod-shaped brush parts 5 a but are reliably contacted with the brush parts 5 a and guided to the tablet guide part 13 .

[0102] like Fig. 9 As shown in (a), the following situation sometimes occurs: the tablet T entering the tablet guide portion 113, especially in the case of a half tablet, the corners located at the lower ends of the sharp points in the chord direction will be stuck on the upper end of the tablet guide portion 113b below the circumferential groove 114, so that it cannot be separated by the unillustrated partition member located in the circumferential groove 114, thereby hindering the discharge of the tablet.

[0103] In this embodiment, if Fig. 9 As shown in (b), a chamfered portion 13c is provided on the upper end of the tablet guide portion 13b below the circumferential groove 14, so that in the tablet guide portion 13, the corner of the half tablet will not be stuck on the upper end of the tablet guide portion 13b below the circumferential groove 14, but will fall downward as shown by the double-dotted line. Fig. 9 As shown in (c), the width of the tablet guide portion 13b below the circumferential groove 14 may be made larger than the width of the tablet guide portion 13a above the circumferential groove 14. In this case as well, when the tablet T is a half tablet, the corner of the half tablet does not get caught on the upper end of the tablet guide portion 13b below the circumferential groove 14, but falls downward as shown by the two-dot chain line.

[0104] In addition, if Fig.10 As shown in (a), sometimes, when the tablet guide 113 is a rectangular groove, the corner of the tablet T entering the tablet guide 113, which is located in the diagonal direction of the tablet T, interferes with the groove bottom of the tablet guide 113 and the inner surface of the rotating member receiving portion 106, thereby hindering the rotation of the rotating member 103. Fig.10 As shown in (b), when the tablet guide 113 is a closed circle, the tablet is placed between the tablet guide 113 and the outer peripheral surface of the rotating member 103 , so that the tablet T cannot enter the tablet guide 113 .

[0105] In this embodiment, if Fig.10 As shown in (c), the cross section of the tablet guide portion 13 in the axial direction perpendicular to the rotating member 3 is formed as a groove in the shape of a circular segment. Therefore, in the tablet guide portion 13, the tablet will not interfere with the inner surface of the rotating member accommodating portion 6 to hinder the rotation of the rotating member 3, so that the tablet can be reliably discharged.

[0106] <Variation Example 1>

[0107] In the above embodiment, the tablet introduction member 5 is fixed to the tablet receiving portion 2, but the tablet introduction member 5 may also be Fig.11 As shown in FIG. 1 , the tablet introducing member 5 is arranged to be able to move forward or backward relative to the tablet containing portion 2. The moving mechanism of the tablet introducing member 5 may use a motor or a solenoid powered from the mounting portion on which the tablet dispensing device 1 is mounted.

[0108] In this modified example, when the tablet storage capacity in the tablet storage section 2 exceeds a predetermined amount, the tablets are likely to enter the tablet guide section 13, so the tablet introduction member 5 is retracted as shown by the double-dashed line. When the tablet storage capacity in the tablet storage section 2 becomes less than the predetermined amount, the tablet introduction member 5 is advanced as shown by the solid line. As described above, the tablets are reliably contacted with the tablet introduction member 5 and are guided to the tablet guide section 13, thereby preventing the tablets from being retained on the rotating member 3.

[0109] <Variation 2>

[0110] In addition, in the tablet introduction member 5 of the above embodiment, the brush portion 5a extends linearly, but a rod-shaped body having an S-shaped root or middle portion when viewed from above or from the side, so that the distance from the root to the front end is long and the rod-shaped body is easily bent can also be used.

[0111] <Variation 3>

[0112] Furthermore, in the above embodiment, the three brush parts 5 a all have the same function of guiding the tablets retained on the rotating member 3 to the tablet guide part 13 , but the three brush parts 5 a may have different functions.

[0113] The details are as follows. Fig.11A As shown in (a), the tablet introduction component 5 has a first brush portion 5a1, a second brush portion 5a2, and a third brush portion 5a3 in order from the upstream side in the rotation direction of the rotating member. The root portions of the first brush portion 5a1 and the third brush portion 5a3 are integrally provided with the support portion 5b. Fig.11A As shown in (b), the second brush portion 5a2 has a base portion 5d that can be mounted or removed relative to the support portion 5b. The height of the front end of the second brush portion 5a2 can be adjusted by engaging the base portion 5d in any one of the three-layer engaging portions 5f selected from the upper and lower layers, wherein the three-layer engaging portions 5f are formed on the side edge of the rectangular hole 5e formed on the support portion 5b.

[0114] like Fig. 11BAs shown in FIG. 1 , when viewed from the side, the first brush portion 5a1, the second brush portion 5a2, and the third brush portion 5a3 are all formed in an S shape. Therefore, the stroke from the root to the front end becomes longer, thereby reducing the reaction force received by the front end from the half tablet, and in the forward and reverse movements of the rotating member, as shown in FIG. Fig. 11C As shown in , when a reaction force acts on either side in the left or right direction when viewed from above, the tablet is deformed in the same manner, thereby producing the same effect of guiding the tablet into the tablet guide.

[0115] In addition, if Fig. 11B As shown in FIG, the positions of the front ends of the first brush portion 5a1, the second brush portion 5a2, and the third brush portion 5a3 are different.

[0116] The front ends of the first brush portion 5a1 and the second brush portion 5a2 are Figure 6 The tablet introduction member 5 is similarly located above the rotating member 3, wherein the front end of the first brush portion 5a1 is located above the front end of the second brush portion 5a2.

[0117] The third brush portion 5a3 enters the outer peripheral recess 15 formed on the side surface of the rotor 3 along the circumferential direction. The outer peripheral recess 15 is located above the circumferential groove 14 and is formed to be shallower than the depth of the tablet guide 13 and the circumferential groove 14.

[0118] Therefore, if Fig.11D As shown in the figure, the tablet Ta retained on the rotating member 3 is pushed or bounced by the first brush portion 5a1 and gathered as described in the first embodiment, and is guided to the subsequent tablet guide portion 13. In addition, the tablet Tb stuck at the entrance of the tablet guide portion 13 does not contact the first brush portion 5a1, but is bounced by the second brush portion 5a2 and is scraped to the tablet guide portion 13. Furthermore, the tablet Tc stuck in the circumferential groove 14 inside the tablet guide portion 13 does not contact the first brush portion 5a1 and the second brush portion 5a2, but is bounced by the third brush portion 5a3 and is guided to the bottom of the tablet guide portion 13.

[0119] In the above-described embodiment, each brush portion is provided with elasticity by being formed in an S-shape, but the base of the brush portion may be attached to the support portion via a spring member, thereby providing elasticity by the spring member.

[0120] <Second embodiment>

[0121] Fig.122 shows a tablet dispensing device 21 of a second embodiment of the present invention. Similar to the tablet dispensing device 1 of the first embodiment, the tablet dispensing device 21 is detachably mounted on a mounting portion (motor seat) not shown in the figure, and can dispense tablets in a quantity corresponding to a prescription. The tablet dispensing device 21 includes a tablet storage portion 22, a rotating member 23, and a partition member 24.

[0122] The tablet storage section 22 is a rectangular container with an opening at the top, and has a bottomed cylindrical rotating member storage section 25 at the bottom thereof. On the upper edge of the tablet storage section 22, a cover body (not shown) is rotatably provided via a hinge, and the upper opening of the tablet storage section 22 can be opened or closed by the cover body. The rotating member 23 is rotatably accommodated in the rotating member storage section 25. A tablet outlet 25a is formed on the rear bottom surface of the rotating member storage section 25. On the rear side surface of the rotating member storage section 25 and above the tablet outlet 25a, a cutout 25b for inserting the partition member 24 is formed in a manner extending in the circumferential direction of the rotating member storage section 25. On the bottom surface of the rotating member storage section 25, a rotating member drive shaft 26 extending in the axial direction of the rotating member storage section 25 is rotatably provided.

[0123] Regarding the rotating member 23, it is not configured in a manner such that the partition member 4 is separated into upper and lower parts in the tablet guide portion 13 as in the first embodiment, but a partition member 24 is configured in an annular groove portion (pocket) 27 between the rotating member 23 and the rotating member receiving portion 25 to restrict the tablets from entering the tablet guide portion 40 of the rotating member 23, which is a so-called single-stage rotating member.

[0124] The rotor 23 is composed of an upper first rotor 28 and a lower second rotor 29. The first rotor 28 and the second rotor 29 are coaxially arranged around the rotor drive shaft 26 and rotate at different rotation speeds.

[0125] A first rotating member gear 30 for driving the first rotating member 28 is mounted at the lower end of the rotating member driving shaft 26. The first rotating member gear 30 meshes with a first intermediate gear 31 provided on the outer surface of the bottom of the rotating member receiving portion 25. When the tablet receiving portion 22 is mounted on a mounting portion (not shown), the first intermediate gear 31 meshes with a motor gear of the mounting portion, whereby when the motor in the mounting portion is driven, the first rotating member 28 is rotated via the motor gear, the first intermediate gear 31 and the first rotating member gear 30.

[0126] A transmission gear 32 for transmitting power to the second rotating member 29 is installed on the middle portion of the rotating member driving shaft 26. The transmission gear 32 meshes with a second intermediate gear 33 provided on the bottom inner surface of the rotating member accommodating portion 25. The second intermediate gear 33 has an A gear 33a meshed with the transmission gear 32, and a B gear 33b meshed with the second rotating member gear 37 of the second rotating member 29. When the rotating member driving shaft 26 rotates, the intermediate shaft 33c of the second intermediate gear 33 rotates via the transmission gear 32 and the A gear 33a of the second intermediate gear 33, and the second rotating member 29 rotates via the B gear 33b of the second intermediate gear 33 and the second rotating member gear 37.

[0127] like Fig.13 As shown in FIG. 1 , the top surface of the first rotating member 28 is formed in a conical shape, and a plurality of stepped portions 28a for tablet stirring are formed at three locations in the circumferential direction of the top surface. A cover 34 is installed at the center of the top surface of the first rotating member 28. Fig.14 As shown, the bottom surface of the first rotating member 28 is formed with a recessed portion 28b that fits with the protruding portion 29a of the second rotating member 29. At the lower edge of the outer peripheral surface of the first rotating member 28, protrusions 35 that protrude radially outward are formed at positions divided into four equal parts in the circumferential direction.

[0128] When viewed from the side of the first rotating member 28, Fig.15 As shown in (a), the protrusion 35 is formed in a substantially right triangle shape, and the protrusion 35 has: an inclined surface 35a, which is located on the downstream side of the rotation direction of the first rotating member 28 and is inclined upward toward the upstream side of the rotation direction of the first rotating member 28; a vertical surface 35b, which is located on the upstream side of the rotation direction of the first rotating member 28 and extends along the axial direction of the first rotating member 28; a curved surface 35c, which connects the upper end of the inclined surface 35a and the upper end of the vertical surface 35b; and a bottom surface 35d, which is flush with the lower surface of the first rotating member 28. Fig.12 As shown, the first rotating member 28 is engaged and fixed to the upper end of the rotating member driving shaft 26 so as to be able to rotate integrally with the rotating member driving shaft 26 .

[0129] like Fig.14As shown, the top surface of the second rotating member 29 is formed with a convex portion 29a that engages with the concave portion 28b of the first rotating member 28, and the lower portion of the second rotating member 29 is formed with a gear space 29b that accommodates the second intermediate gear 33 described later. A shaft portion 36 is formed in the center of the second rotating member 29, and the shaft portion 36 has a center hole 36a for the rotating member drive shaft 26 to pass through. Around the shaft portion 36, a second rotating member gear 37 that drives the second rotating member 29 is installed in a manner that allows it to rotate integrally with the second rotating member 29. An O-ring 38 that acts as a torque limiter is installed between the second rotating member gear 37 and the shaft portion 36 of the second rotating member 29. Similarly, as Fig.12 As shown, an O-ring 39 is also installed between the rotating member drive shaft 26 and the first rotating member gear 30 to function as a torque limiter.

[0130] like Fig.14 As shown in FIG. 1 , the outer circumference of the second rotating member 29 has a small diameter portion 29c having the same diameter as the outer circumference of the first rotating member 28, a large diameter portion 29d located below the small diameter portion 29c and having a larger diameter than the small diameter portion 29c, and a step portion 29e formed between the small diameter portion 29c and the large diameter portion 29d. A groove-shaped tablet guide portion 40 extending in the axial direction is formed at a position where the large diameter portion 29d is divided into eight equal parts in the circumferential direction. Fig.15 As shown in (a), an inclined surface 40b that is inclined upward toward the upstream side of the rotating element rotation direction of the tablet guide 40 is formed between the side surface 40a on the upstream side of the rotating element rotation direction of the tablet guide 40 and the step portion 29e. In addition, a chamfered portion 40d is formed at the corner between the side surface 40c on the downstream side of the rotating element rotation direction of the tablet guide 40 and the step portion 29e.

[0131] The rotation speed of the first rotating member 28 and the second rotating member 29 can be adjusted by changing the number of teeth of the B gear 33b of the second intermediate gear 33 (replacing it with a B gear with a different number of teeth). For example, when the first rotating member gear 30 and the transmission gear 32 are set to 24 teeth, the A gear 33a of the second intermediate gear 33 is set to 10 teeth, the B gear 33b of the second intermediate gear 33 is set to 11 teeth, the second rotating member gear 37 is set to 23 teeth, and the rotation speed of the transmission gear 32 is set to 100rpm, the rotation speed of the second rotating member gear 37 is 114.8rpm, which can obtain a rotation speed of about 1.1 times the rotation speed of the first rotating member gear 30.

[0132] like Fig.13 As shown, the partition member 24 is composed of a brush portion 24a, a support portion 24b and a mounting portion 24c, and is mounted on the tablet storage portion 22 above the tablet outlet 25a. The brush portion 24a is mounted so that its front end is located between the protrusion 35 of the first rotating member 28 and the step portion 29e of the second rotating member 29.

[0133] Next, the operation of the tablet dispensing device 21 of the above embodiment will be described.

[0134] A large number of half tablets contained in the tablet containing part 22 are stirred as the rotating member 23 rotates, and enter the annular groove part 27 surrounded by the inner surface of the rotating member containing part 25, the outer peripheral surface of the first rotating member 28, the small diameter part 29c of the second rotating member 29, and the stepped part 29e. Further, the tablets in the groove part 27 enter the tablet guide part 40 of the second rotating member 29. When the tablet guide part 40 approaches the tablet outlet 25a as the rotating member 23 rotates, the tablets in the tablet guide part 40, that is, the tablets below the partition member 24, are discharged from the tablet outlet 25a and are discharged after passing through the mounting part (not shown). Each time the tablet guide part 40 passes through the tablet outlet 25a, one tablet is discharged, thereby packaging and dispensing the tablets corresponding to the prescription.

[0135] When the number of remaining tablets in the tablet storage section 22 decreases, in the prior art, the tablets placed on the partition member 24 are retained on the partition member 24 and cannot be discharged, and the tablets placed on the step portion 29e of the rotating member 23 rotate together with the rotating member 23 and cannot be discharged.

[0136] In the tablet dispensing device 21 of this embodiment, the first rotating member 28 and the second rotating member 29 have different rotation speeds, and the first rotating member 28 is provided with a protrusion 35 , so that the tablets retained above the partition member 24 and the stepped portion 29 e are reliably guided to the tablet guide portion 40 .

[0137] Further details are as follows. Fig.15 As shown in (a), the tablet T retained on the partition member 24 passes through the inclined surface 35a of the protrusion 35 of the first rotating member 28 moving from the upstream side in the rotating direction of the rotating member, as shown in FIG. Fig.15 As shown in (b) in FIG. 1 , the rotatable member is pushed to the downstream side in the rotation direction of the rotating member and leaves the partition member 24, and moves to the step portion 29e of the second rotating member 29, and then as shown in FIG. Fig.15 As shown in (c) in the figure, the tablet enters the tablet guide 40 and is discharged.

[0138] like Fig.16As shown, since the rotation speed of the first rotating member 28 is greater than that of the second rotating member 29, the tablets retained on the step 29e of the second rotating member 29 abut against the inclined surface 35a of the protrusion 35 of the first rotating member 28 rotating relative to the second rotating member 29, and are pushed to the downstream side of the rotating member rotation direction, and then enter the tablet guide 40 and are discharged. The inclined surface 35a is inclined upward toward the upstream side of the rotating member rotation direction, so the tablets are lifted by the inclined surface 35a and tilted along the inclined surface 35a, so that the tablets smoothly enter the tablet guide 40.

[0139] Since an inclined surface 40b is formed between the side surface 40a on the upstream side of the rotating part of the tablet guide part 40 and the step portion 29e, which is inclined downward toward the downstream side of the rotating part in the rotation direction, when the tablet is pushed by the protrusion 35 of the first rotating part 28 and approaches the tablet guide part 40, the tablet will tilt along the inclined surface 40b and smoothly enter the tablet guide part 40.

[0140] If the tablet is clamped between the first rotating member 28 and the tablet guide portion 40 to form a block, the O-ring 38 between the second rotating member gear 37 and the shaft portion 36 of the second rotating member 29 acts as a torque limiter, so that the first rotating member 28 slips and the second rotating member 29 is reversed relative to the first rotating member 28. As a result, the force of the protrusion 35 of the first rotating member 28 pressing the tablet is reduced, and the bridging phenomenon of the tablet is eliminated.

[0141] In the above embodiment, both the O-ring 39 on the first rotating element gear side and the O-ring 38 on the second rotating element gear side are provided as the torque limiter, but only one of them may be provided.
