The present invention relates to a bag-filled medicine dispensing device.

2. Description of the Related Art Conventionally, a payout device having a configuration in which a spiral wire is disposed around a rotation shaft and accommodated in a casing is known (see, for example, Patent Documents 1, 2, and 3). In this type of dispensing device, products are arranged in two rows on the left and right sides with a rotating shaft, and the spiral wire is rotated by 180 °, so that the products are dispensed one by one.

Japanese Patent No. 2058246 JP-A-4-314194 Japanese Patent Laid-Open No. 56-114092

However, none of the above dispensing devices has a configuration suitable for dispensing a medicine in a bag. That is, the medicine in a bag contains a hard medicine such as an ampoule, and the bag is made of a soft material such as polyethylene. When the spiral wire is rotated, the medicine in the bag descends while rotating around the rotation axis together with the spiral wire while being guided by the inner surface of the casing. For this reason, there is a possibility that the soft bag is deformed, and a part of the medicine in the bag falls into the inner space of the spiral wire and becomes clogged, making it impossible to appropriately convey and dispense.

Therefore, an object of the present invention is to provide a bag-filled medicine dispensing device that can properly convey even a bag-filled medicine without causing clogging and reliably dispense one by one.

As a means for solving the above-mentioned problems, the present invention provides a medicine dispensing apparatus, an apparatus main body having an internal space extending from one end side toward the other end side and having a discharge portion on the other end side, and a spiral shape A holding member that is arranged in the internal space of the apparatus main body along the direction in which the axial direction extends, and an inner space of the holding member is arranged along the axial direction. A partition plate, and a drive unit that rotates the holding member and sequentially discharges the medicine in the bag held in each region formed by the holding member and the partition plate to the discharge unit; It is a thing.

With this configuration, when the holding member is rotated, the medicine in the bag held in each region is prevented from moving in the rotation direction by the partition plate. Thereby, the medicine in the bag moves downward by one step according to the spiral shape every time the holding member rotates without changing the position in the rotation direction. And the medicine in a bag located in the lowest part loses support by a holding member, and is paid out. In this case, since the medicine in the bag can be guided in a wide range by the partition plate, the medicine in the bag is not sufficiently transported in the spiral direction, and does not fall into the inner space of the holding member and is smooth. Can be paid out.

It is preferable that the partition plate includes a protrusion that bulges in the thickness direction.

With this configuration, it is possible to prevent the medicine in the bag from falling into the inner space of the holding member even more reliably.

The protrusion is preferably formed on the upstream side in the rotation direction of the holding member.

With this configuration, the medicine in the bag is pressed in the spiral direction by the protrusion, and the medicine in the bag is not only prevented from falling into the inner space of the holding member, but can be smoothly conveyed in the spiral direction. .

It is preferable that the partition plate is provided with a protruding portion that further protrudes from the protruding portion on the discharge portion side.

With this configuration, it is possible to forcibly correct the position of the medicine in the bag that could not be corrected by the protrusions before discharging from the apparatus main body, and to dispense smoothly.

It is preferable that the protrusion has an inclined portion that gradually approaches the partition plate toward the discharge portion.

With this configuration, it is possible to prevent a problem that the medicine in the bag is clogged by being sandwiched between the protruding portion and the inner surface of the apparatus main body at the bottom.

It is preferable that the partition plate has an excision part at the end part on the discharge part side so as to be partly non-contact with the bagged medicine.

With this configuration, since the medicine in the bag can avoid friction with the partition plate at the lowermost portion by the excision part, it is warped by friction with the partition plate, and as a result, clogging does not occur.

The apparatus main body is arranged so that the internal space is along the vertical direction and one end side is located on the upper side, and the holding member is made of a spiral wire, and the end portion on the discharge side of the spiral wire is the outer periphery. The discharge portion of the apparatus main body is a position where the support of the medicine in the bag by the inclined portion and the outer peripheral portion connected thereto is released by the rotation of the inclined plate and the spiral wire. It is preferable to provide a notch for avoiding interference with the bag-filled medicine on the front side corresponding to.

With this configuration, at any of the two positions where the support of the spiral wire is released, it is possible to pay out while suppressing the impact force applied to the bag-filled medicine by the inclined plate. In particular, when the position where the support of the spiral wire is released is on the upper side of the inclined plate, interference with the bag-filled medicine can be avoided by the notch. Therefore, since it can arrange | position in the vicinity of the bag-filled medicine which pays out an inclination board, it becomes possible to relieve an impact force.

According to the present invention, since the partition plate that bisects the internal space is provided in the internal space of the spiral holding member, the partition is sequentially separated by the holding member and the partition plate by rotating the holding member. The medicines in the bags placed in the space thus formed can be discharged one by one. The partition plate appropriately prevents clogging of the medicine in the bag and realizes a smooth dispensing operation.

Embodiments according to the present invention will be described below with reference to the accompanying drawings. In the following description, terms indicating specific directions and positions (for example, terms including “up”, “down”, “side”, “end”, etc.) are used as necessary. The use is intended to facilitate understanding of the invention with reference to the drawings, and the technical scope of the present invention is not limited by the meaning of these terms.

(Constitution)
1 and 2 show a bag-type medicine dispensing device according to the present embodiment. This bag-filled medicine dispensing device generally has a configuration in which a spiral wire 2 and a partition plate 3 are accommodated in a device body 1.

The apparatus main body 1 has a hollow, substantially rectangular parallelepiped shape, and the front opening is opened and closed by the front door 4. A support plate 6 is fixed to the upper end portion of the back plate 5 of the apparatus body 1 as shown in FIG. The support plate 6 protrudes inside the apparatus main body 1, and a support portion 7 having a substantially U-shaped cross section is formed on the tip side. An upper end shaft portion 2 a of a spiral wire 2 described later is rotatably supported by the support portion 7 via a bearing 8. A motor 10 covered with a casing 9 is disposed on the upper surface of the support plate 6. A gear 10 b is fixed to the rotating shaft 10 a of the motor 10 and meshes with a gear 2 b fixed to the upper end shaft portion 2 a of the spiral wire 2. Thereby, when the motor 10 is driven, the spiral wire 2 rotates through the

gears

10b and 2b. A protrusion partitioning portion 11 extending in the vertical direction is integrated with the front central portion of the back plate 5. The protrusion partitioning part 11 divides the internal space of the apparatus main body 1 into left and right parts along the vertical direction with a partition plate 3 to be described later.

As shown in FIG. 2, an inclined plate 12 is attached to the lower part of the apparatus main body 1, which is gradually inclined downward as it goes to the back side. Guide pieces 13 are formed on both side edges of the inclined plate 12 by being bent at a substantially right angle. The guide piece 13 is provided with an optical sensor 15 comprising a light emitting element and a light receiving element for detecting the bag-filled medicine 14 that has slid down the inclined plate 12. Moreover, the lower part back surface of the apparatus main body 1 is excised, and interference with the bag-filled medicine 14 that has slid down the inclined plate 12 is avoided. In particular, the left half is formed with a notch 16 having an excision range extending upward.

As shown in FIG. 3, the spiral wire 2 includes a spiral wire portion 17 and a disk portion 18 integrated with an upper end portion of the wire portion 17. An upper end shaft portion 2a is formed at the center of the disk portion 18, and a gear 2b is integrated with the tip portion thereof. As shown in FIG. 4, the lower end side of the wire portion 17 includes a radius portion 19 that is bent inward so that the distal end portion is located at the center portion, and a cylindrical portion 20 that is formed at the distal end portion. Has been. A shaft portion 21 of a partition plate 3 to be described later passes through the tube portion 20, and the spiral wire 2 is rotatably supported.

The partition plate 3 is disposed on the inner periphery of the spiral wire 2 so as to cross the center thereof. And as shown in FIG. 4, the axial part 21 protrudes in the center of the lower end part of the partition plate 3, and the cutting part 22 is formed in the one side. The shaft portion 21 penetrates the cylindrical portion 20 of the spiral wire 2 and supports the spiral wire 2 in a rotatable manner. The tip portion of the shaft portion 21 is formed in a substantially D-shaped cross section and is fixed to the support member 23. The support member 23 is fixed to the inclined plate 12, whereby the partition plate 3 is positioned with respect to the inclined plate 12, and the inside of the casing 9 is divided into left and right as viewed from the front opening side. The excision part 22 is formed at a position facing the radius part 19 of the spiral wire 2 and prevents clogging when the lowermost bag-filled medicine 14 is dispensed. That is, when there is no excision part 22, the bag-filled medicine 14 located at the lowermost end warps upward on the surface of the partition plate 3 due to friction, and as a result, the bag-filled medicine 14 sticks to the partition plate 3. It becomes. The cutting section 22 avoids friction with the bagged drug 14, and the bagd drug 14 is not attached to the partition plate 3.

Further, on the front and back surfaces of the partition plate 3, protrusions 24 are respectively attached along both side edges. The protrusion 24 is provided on the upstream side with respect to the rotational direction of the spiral wire 2. The four sides of the surface of the ridge 24 (the surface that directly contacts the bag-filled drug 14) are formed in an R shape so as not to damage the bag-filled drug 14. The protrusion 24 prevents the bag-filled medicine 14 from falling into the inner space of the spiral wire 2 due to the rotation of the spiral wire 2. Further, as the spiral wire 2 rotates, the ridge portion 24 relatively presses the bag-filled drug 14 in the spiral direction along the spiral shape, thereby enabling smooth conveyance of the bag-filled drug 14. .

In addition, a protrusion 25 is provided below the bulge. The protruding portion 25 is formed in a substantially triangular shape having a portion further protruding than the protruding portion 24. The protruding portion 25 is formed so as to protrude from the protruding portion 25 at a portion overlapping the protruding portion 24 and gradually approach the partition plate 3 toward the lowest end where the protruding portion 24 is not located. Has been. And the protrusion part 25 plays the role which returns the chemical | medical agent 14 with the bag conveyed to the lowest end finally to a regular position.

(Operation)
Next, the operation of the bag-filled medicine dispensing device having the above configuration will be described.

In the medicine dispensing device, the space in the casing 9 is divided into left and right parts by the partition plate 3 and divided into a plurality of stages in the vertical direction by the spiral wire 2. Therefore, when setting the medicine 14 in a bag, the front door is opened, and the medicine 14 in a bag can be inserted into each space area partitioned by the spiral wire 2, the partition plate 3, and the casing 9 from the front side. When the insertion of the bagged medicine 14 is completed, the front door is closed to prepare for the dispensing instruction.

When a payout command (for example, prescription data) is input, the spiral wire 2 is rotated by driving the motor 10. The amount of rotation of the spiral wire 2 is set to a half pitch at which the radius portion 19 rotates half a round, that is, 180 degrees. Thereby, the bag-containing medicine 14 held in each region is moved downward by one step along the spiral shape each time the spiral wire 2 rotates while being prevented from moving in the rotational direction by the partition plate 3. And move. At this time, a frictional force acts on the medicine 14 in the bag by the rotation of the spiral wire 2 and is pressed against the partition plate 3, but is prevented from falling into the spiral wire 2 by the protrusion 24. Here, the protrusion 24 is provided on the upstream side in the rotation direction of the spiral wire 2. Thereby, when the medicine 14 is pressed against the partition plate 3 by the rotation of the wire 2, the bag-containing medicine 14 is also pushed out to the downstream side. Therefore, the portion located on the upstream side of the bag-filled medicine 14 does not move to the inside of the spiral wire 2 and fall.

The bag-containing medicine 14 located at the lowermost part is further adjusted to a position suitable for dispensing by the protrusion 25. Further, the protrusion 24 is not formed on the lower end side of the partition plate 3 and the protruding portion 25 is gradually inclined toward the partition plate side, so that the bag-filled medicine 14 protrudes from the inner surface of the apparatus main body 1. It is not pinched between the strips 24. Further, in the region on the back side in FIG. 3, the bag-containing medicine 14 loses the support of the spiral wire 2 from the portion corresponding to the lower side of the inclined plate 12 and falls to the inclined plate 12. On the other hand, in the region on the near side in FIG. 3, the bag-containing medicine 14 loses support by the spiral wire 2 from the portion corresponding to the upper side of the inclined plate 12 and falls to the inclined plate 12. In this case, the medicine 14 in the bag placed on the spiral wire 2 may be pushed out in the horizontal direction by the frictional force from the spiral wire 2. However, since the notch 16 is formed on the lower back surface of the apparatus main body 1, the medicine 14 in the bag smoothly passes through the notch 16 to the inclined plate 12 without interfering with the back surface of the apparatus main body 1. To be paid out.

The bag-filled medicine 14 dispensed to the inclined plate 12 is detected by the optical sensor 15 when sliding down the inclined surface, and the number of dispenses is counted. Therefore, when the count reaches a predetermined value, the driving of the motor 10 is stopped and the rotation of the spiral wire 2 is stopped.

As described above, according to the embodiment, since the inner space of the spiral wire 2 is divided into two by the partition plate 3, the bag-filled medicine 14 held in each region is smoothly moved by the rotation of the spiral wire 2. It is transported downward. Moreover, since the protrusions 24 are provided on the partition plate 3, the bag-filled medicine 14 does not fall inside the spiral wire 2, and clogging does not occur. Furthermore, since the protrusion 25 is provided at the lower end of the partition plate 3, the position of the bag-filled medicine 14 is corrected immediately before the dispensing, and a satisfactory dispensing operation can be realized.

In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

For example, the positioning of the partition plate 3 in the spiral wire 2 with respect to the rotational direction is performed by making the shaft portion 21 at the center of the lower end portion into a substantially D-shaped cross section, but the cross-sectional shape of the shaft portion 21 is not limited thereto. Various shapes such as a triangle and a quadrangle can be used. Further, it can be configured to be directly fixed to the support member by adhesion, welding or the like. Further, the shaft portion 21 may be extended to be fixed directly to the apparatus main body 1 or the inclined plate 12 instead of connecting the shaft portion 21 to the support member 23. In short, any configuration may be used as long as the partition plate 3 can be positioned in the rotation direction without hindering the dispensing operation of the medicine 14 in the bag.

Moreover, although the medicine dispensing device is arranged vertically, it can be arranged so as to be inclined or arranged horizontally so that it can be dispensed from the side.

It is a perspective view of the medicine delivery device concerning this embodiment. It is a perspective view which shows the state which looked at the chemical | medical agent dispensing apparatus of FIG. 1 from the back side. FIG. 2 is a perspective view in a state where an apparatus main body and the like are removed from FIG. 1. It is a partial expansion perspective view of a spiral wire and a partition plate.
