The utility model discloses in, a dispensing platform 1 for automatic dispensing can be called dispensing platform 1 for short. In addition, the utility model relates to a dispensing table 1, it can be used for herbal pieces-'s automatic dispensing.

The utility model relates to a in dispensing table 1, can carry out the dispensing to single herbal pieces-ready prepared for use through dispensing equipment 10 to mix each herbal pieces-ready prepared for use through gathering together belt 20 and smooth groove 30, thereby accomplish single dose herbal pieces-ready prepared for use's automatic dispensing, follow the circulation of dose in the herbal pieces-ready prepared for use prescription and transfer, thereby accomplish the automatic dispensing to herbal pieces-ready prepared for use prescription.

Fig. 1 is a schematic structural diagram showing a dispensing table 1 for automated dispensing according to an example of the present invention. Fig. 2 is a schematic structural diagram showing a dispensing apparatus 10 according to an example of the present invention.

As shown in fig. 1, the present invention relates to a dispensing station 1 for automated dispensing, which may include a dispensing apparatus 10, a gathering belt 20, and a chute 30.

As mentioned above, the dispensing station 1 may comprise a dispensing device 10. In some examples, as shown in fig. 2, the dispensing apparatus 10 may include a storage portion 11, a feeding portion 12, and a delivery portion 13. Wherein, the storage part 11 can be connected with the feeding part 12, and the feeding part 13 can be positioned at the downstream of the feeding part 12.

In some examples, the storage 11 may be used to store materials. That is, the storage part 11 can temporarily store the materials. In addition, the material in the storage part 11 may be manually prepared and loaded. In addition, the amount of the material in the storage part 11 is not less than the total amount required for dispensing (for example, the total weight of the single Chinese medicinal decoction pieces according to the prescription).

In some examples, as shown in fig. 2, the storage part 11 may have a feed opening 111 and a drop opening 112. In this case, the feed opening 111 can be used for feeding the material in the storage portion 11, and the drop opening 112 can be used for discharging the material in the storage portion 11.

In some examples, the drop opening 112 of the reservoir 11 may be disposed downstream of the reservoir 11. In addition, in some examples, the feed opening 111 of the storage part 11 may be provided at a side surface of the storage part 11 connected to the bottom surface. Thereby, the matching of the feed port 111 and the cabinet 40 for placing the material can be facilitated. In other examples, the position where the feed port 111 is disposed in the storage part 11 may be located upstream of the drop port 112.

In some examples, the feed port 111 is positioned away from the drop port 112. In other examples, the feed port 111 may not be in contact with the drop port 112. Further, in some examples, the feed port 111 may be parallel to the drop port 112.

In some examples, the drop opening 112 may be larger than the feed opening 111. In other examples, the reservoir 11 may gradually expand from the feed opening 111 to the drop opening 112. Thereby, the passage of material through the drop opening 112 can be facilitated.

In some examples, the reservoir 11 may be funnel-shaped. Specifically, the storage part 11 is tapered from the feed opening 111 to the drop opening 112, so that the material (for example, decoction pieces of chinese medicine) fed from the feed opening 111 to the storage part 11 can be collected at the drop opening 112. In other examples, the storage portion 11 may have a cylindrical shape, a prismatic shape, or the like.

In addition, in some examples, the feed opening 111 and the drop opening 112 may be connected in an arc shape. For example, the feed opening 111 and the blanking opening 112 are connected in an outwardly curved arc, thereby slowing down the sliding speed of the material along the arc surface in the storage part 11.

In some examples, the storage part 11 may further include a sidewall connecting between the feed opening 111 and the drop opening 112, the sidewall forming an angle with a horizontal plane. This can reduce the occurrence of the clogging in the storage portion 11. In other examples, the sidewall may form an angle with the horizontal that is 40 ° to 90 °. That is, the drop opening 112 of the storage part 11 may form an inclination angle with the horizontal plane.

In some examples, the storage portion 11 may also be provided with a striker plate (not shown). Specifically, the striker plate may be disposed at the blanking port 112 of the storage part 11 and used to cover the blanking port 112. When the feeding is not needed, the material baffle is normally closed to keep the material in the storage part 11; when the material needs to be fed, the material stop plate is opened, so that the material is sent out from the blanking port 112. This enables the amount of feed from the reservoir 11 to be effectively controlled.

In some examples, the storage portion 11 may further include an auxiliary feeding portion disposed near the blanking port 112, and the auxiliary feeding portion is used for stirring the herbal pieces near the blanking port 112 to discharge the herbal pieces from the blanking port 112. In this case, the auxiliary feeding part can uniformly convey the herbal pieces to the feeding part 12 from the blanking port 112. In particular, the auxiliary charging part may comprise at least two metal rods in different directions. Thus, the metal rod can stir the material by rotating.

In other examples, as shown in fig. 2, the blanking opening 112 may also be connected to the feeding portion 12 via a fixing frame 125 (described later). This ensures that the material from the storage portion 11 is sent to the charging portion 12.

In some examples, the striker plate may be manually controlled, whereby an operator can manually control the amount of feed of the reservoir 11. In other examples, the striker plate may also be electrically controlled, in which case the amount of feed of the reservoir 11 can be accurately controlled by the electrical control.

In the present invention, generally speaking, "herbal pieces" refers to the Chinese traditional medicine which is processed and concocted according to the theory of traditional Chinese medicine and the concocting method of traditional Chinese medicine and can be directly used in clinical practice of traditional Chinese medicine. The herbal pieces in the present embodiment include, but are not limited to, rhizomes, seeds, fruits, flowers, leaves, herbs, bark, minerals, and animals, and the pieces may be in the form of tablet, granule, foam, floss, etc.

Fig. 3 is a schematic side view illustrating a dispensing apparatus 10 according to an example of the present invention.

In some examples, as described above, the charging portion 12 may be connected to the storage portion 11, and the charging portion 12 may be located downstream of the drop opening 112, as shown in fig. 1 and 3. In other examples, the charging portion 12 may receive material from the drop opening 112. In the present invention, a material such as herbal pieces can be fed to the downstream feeding portion 12 via the upstream storage portion 11.

In some examples, as shown in fig. 1, the charging portion 12 may include a first mandrel 121 and a second mandrel 122. Wherein the second shaft core 122 may be disposed side by side with the first shaft core 121. In addition, in the charging portion 12, the material can be charged through the gap D between the first shaft core 121 and the second shaft core 122. Thereby, the material flow rate can be controlled by controlling the operation speed of the first and second mandrels 121 and 122.

In some examples, the first core 121 may be elongated. Specifically, the first axial core 121 may have a long-bar shape such as a prism or a cylinder. In the present embodiment, the second shaft core 122 may have the same structure as the first shaft core 121.

In some examples, the first axial core 121 has a first end and a second end (not shown). In some examples, the radius of the first and second ends may be slightly smaller than the first axial core 121. Thereby, the connection with the fixing frame 125 can be facilitated. In some examples, the first and second ends may be integrally formed with the first core 121.

In other examples, the shape of the first core 121 may not be uniform at different locations. For example, the middle portion of the first axial core 121 may have a prism shape, and both ends may have a cylindrical shape.

In some examples, the first and second mandrels 121, 122 may be disposed side-by-side on the same plane. In other examples, as shown in fig. 2, the plane in which the first axis 121 and the second axis 122 are located may form an oblique angle with the horizontal plane. Thereby, it is possible to facilitate the reception of the material (e.g., decoction pieces of chinese medicine) from the obliquely arranged storage part 11. Additionally, in some examples, the plane in which the first and second mandrels 121, 122 lie may be parallel to the horizontal plane.

In some examples, first and second mandrels 121, 122 may run toward each other. The rotation direction L1 of the first shaft core 2 is opposite to the rotation direction L2 of the second shaft core 22, and both rotate in the opposite direction. For example, the first shaft core 121 rotates clockwise, and the second shaft core 122 rotates counterclockwise. In this case, the feeding portion 12 can push the material such as herbal pieces from the storage portion 11 to between the first and second mandrels 121 and 122, and pass the herbal pieces between the first and second mandrels 121 and 122.

In some examples, there may be a rotational speed difference between the operating speed of the first shaft core 121 and the operating speed of the second shaft core 122. This can facilitate control of the flow rate of the material in the charging portion 12. For example, the operating speed of first core 121 may be greater than the operating speed of second core 122, the operating speed of second core 122 may be greater than the operating speed of first core 121, and so on. In other examples, the operating speed of the first shaft core 121 may be the same as the operating speed of the second shaft core 122.

Additionally, in some examples, at least one of first and second mandrels 121, 122 rotates. Specifically, when the first shaft core 121 rotates, the second shaft core 122 may be stopped or may be passively rotated. Similarly, when the second shaft core 122 rotates, the first shaft core 121 may be stopped or may be passively rotated.

In some examples, the center distance of first axis 121 and second axis 122 may be adjustable. Thus, the center distance between the first axial core 121 and the second axial core 122 can be adjusted according to the size and the characteristics of the stored Chinese medicine decoction pieces. In other words, the gap D between the first and second mandrels 121, 122 may be adjustable.

In some examples, the center distance between the first and second mandrels 121, 122 may be adjusted manually or electronically.

In other examples, the center distance between the first axis 121 and the second axis 122 may also be adaptive. Specifically, when the first shaft 121 and the second shaft 122 push the large-sized herbal pieces, the first shaft 121 and the second shaft 122 will automatically separate to both sides. In particular, the adaptation of the center distance between the first and second mandrels 121, 122 may be achieved by mechanical means, such as springs. In addition, the center distance between the first axial core 121 and the second axial core 122 may be adaptive by a driving device, for example, a sensor senses the pressure between the first axial core 121 and the second axial core 122, and when the pressure exceeds a threshold value, the center distance between the first axial core 121 and the second axial core 122 is increased. Under the condition, the putting of the traditional Chinese medicine decoction pieces with large size change can be more effectively controlled.

In some examples, a first rubber layer may be disposed on the outer periphery of the first core 121 and a second rubber layer may be disposed on the outer periphery of the second core 122. In this case, according to the difference of material characteristics, can play the effect of control material transport through controlling first rubber layer and second rubber layer interval.

In addition, the first rubber layer and the second rubber layer can reduce damage to materials (such as original dosage forms), so that the traditional identification characteristics of the materials (such as traditional Chinese medicine decoction pieces) can be maintained, the subsequent rechecking work can be performed simply and quickly, and the generation of noise can be reduced.

In some examples, the first rubber layer and the second rubber layer may be in contact, so that the first rubber layer and the second rubber layer can completely press (block) materials (such as herbal pieces), thereby effectively controlling the delivery of the herbal pieces.

In some examples, for example, when the dispensing apparatus 10 is used to convey materials, the materials pass through the storage portion 11 to the feeding portion 12 and pass between the first and second mandrels 121 and 122 under the pressure of the first and second mandrels 121 and 122. In some examples, when the herbal pieces are passed between the first and second mandrels 121 and 122, the material may be sandwiched between the first and second rubber layers, and even in such a case, the other portions between the first and second mandrels 121 and 122 can be kept in contact, thereby effectively controlling the transportation of the material in the pair of feeding portions 12.

In some examples, a material, such as decoction pieces of herbal medicine, enters between the first and second mandrels 121, 122, and the sum of the thickness of the first and second rubber layers may be at least greater than the size of the material. Thereby, the herbal pieces can be allowed to pass between the first and second mandrels 121 and 122. In this case, the transfer of the material such as the herbal pieces of chinese medicine between the first and second mandrels 121 and 122 can be further effectively controlled.

In some examples, the first rubber layer and the second rubber layer may also be separate from each other. In this case, by adjusting the gap between the first rubber layer and the second rubber layer, the transport of material larger than the sum of the thicknesses of the first rubber layer and the second rubber layer can be controlled.

In some examples, the first and second rubber layers may each be one or more of rubber, fabric, or plastic. Therefore, damage to the materials in the conveying process can be reduced.

In some examples, the first rubber layer and the second rubber layer may each be at least one or more selected from among polyurethane, silicone rubber, nitrile rubber, shadowless rubber (UV), silicone rubber, fluororubber, polysulfide rubber, urethane rubber, chlorohydrin rubber, acrylate rubber, natural rubber, isoprene rubber, styrene-butadiene rubber, chloroprene rubber, flexible ABS, and the like.

In some examples, the first rubber layer may be provided only on the outer periphery of the first shaft core 121. In other examples, the second rubber layer may be provided only on the outer periphery of the second shaft core 122.

In some examples, the first axial core 121 may be provided with a first type of crushing blade thereon. Therefore, the material (such as Chinese herbal pieces) can be crushed, and the dosage form size of the material can be changed. The crushing blade may be fixed to the first shaft core 121 by welding, bonding, or engagement.

In some examples, a plurality of crushing blades of the first type may be disposed on the first spindle 121. In other examples, there may be a space between the crushing blades of the first type on the first mandrel 121. Additionally, in some examples, the spacing between the crushing blades of the first type on the first mandrel 121 may be substantially the same. For example, the crushing blades of the first type on the first spindle 121 may be disposed at predetermined intervals.

In some examples, a first spacer of the type may be disposed on the first core 121. In other examples, the first spacer may be fixed to the first roller core 121 by welding, bonding, snap-fitting, or the like.

In some examples, a plurality of first type spacers may be disposed on the first core 121. In other examples, the first type of spacer may be disposed between the first type of crushing blades. That is, the first type of spacer may be arranged in the spaces between the first type of crushing blades. Thereby, the size of the spacing of the first type crushing blades can be controlled by controlling the size of the first type spacer. For example, the first type of spacer may be arranged within a predetermined spacing between the first type of crushing blades.

In some examples, the thickness of the first type of spacer may be approximately the same. In other examples, the width of the first type of spacer may match the spacing between the first type of crushing blades. For example, the thickness of the spacers of the first type may be approximately the same size as the spacing between the crushing blades of the first type, or the thickness of the spacers of the first type may be slightly smaller than the spacing between the crushing blades of the first type. Thereby, the spacer of the first kind can be arranged just between the crushing blades of the first kind. For example, the thickness of the first type of spacer may be approximately the same as the predetermined spacing between the first type of crushing blades. Additionally, in some examples, the thickness of the first type of spacer may be approximately the same as the width of the first type of crushing blade.

In some examples, a second type of crushing blade may be disposed on the second spindle 122. Therefore, the material (such as Chinese herbal pieces) can be crushed, and the dosage form size of the material can be changed. The crushing blade may be fixed to the second shaft core 122 by welding, bonding, or engagement.

In some examples, a plurality of second type crushing blades may be disposed on the second spindle 122. In other examples, there may be a space between the second type crushing blades on the second spindle 122. Additionally, in some examples, the spacing between the second type of crushing blades on the second spindle 122 may be approximately the same. For example, the crushing blades of the second type on the second spindle 122 may be disposed at predetermined intervals.

In some examples, a second type of spacer may be disposed on the second mandrel 122. In other examples, the second spacer may be welded, bonded, snapped, etc. to the second roller axle 122.

In some examples, a plurality of second-type spacers may be disposed on the second shaft core 122. In other examples, a second type of spacer may be provided between the second type of crushing blades. That is, the second type of spacer may be disposed in the spaces between the second type of crushing blades. Therefore, the size of the interval of the second type crushing blades can be controlled by controlling the size of the second type spacer bush. For example, the second type of spacer may be disposed within a predetermined spacing between the second type of crushing blades.

In some examples, the thickness of the second type of spacer may be approximately the same. In other examples, the width of the second type of spacer may match the spacing between the second type of crushing blades. For example, the thickness of the spacers of the second type may be approximately the same size as the spacing between the crushing blades of the second type, or the thickness of the spacers of the second type may be slightly smaller than the spacing between the crushing blades of the second type. Thereby, the second type of spacer sleeve can be arranged just between the second type of crushing blades. For example, the thickness of the second type of spacer may be approximately the same as the predetermined spacing between the second type of crushing blades. Additionally, in some examples, the thickness of the second type of spacer may be approximately the same as the width of the second type of crushing blade.

In some examples, the first type of crushing blade is configured to be staggered from the second type of crushing blade. In other words, the first type of crushing blades may match the spacing between the second type of crushing blades, which may match the spacing between the first type of crushing blades. That is, the first type of crushing blades may correspond to the interval between the second type of crushing blades, and the second type of crushing blades may correspond to the interval between the first type of crushing blades.

In some examples, the first type of spacer may cooperate with the second type of crushing blade. In other words, the first type of spacer may correspond to the second type of crushing blade. In other examples, the first type of spacer may not be in contact with the second type of crushing blade.

In some examples, the second type of spacer may cooperate with the first type of crushing blade. In other words, the second type of spacer may correspond to the first type of crushing blade. In other examples, the second type of spacer may not be in contact with the first type of crushing blade.

In some examples, the clearance between the first type of crushing blade and the second type of spacer may be substantially the same as the clearance between the second type of crushing blade and the first type of spacer. In addition, the gap between the crushing blades of the first type and the first crushing wall may be substantially the same as the gap between the crushing blades of the first type and the spacer of the second type.

In some examples, the materials crushed into suitable dosage forms can be thrown to the material conveying part 13 through the gaps between the first type crushing blades and the second type spacers and the gaps between the second type crushing blades and the first type spacers. In other examples, material that is broken into a suitable dosage form may be dropped into delivery chute 13 through substantially the same gap. This contributes to improving the consistency of the dosage form of the material delivered from the material-delivering section 12.

In some examples, the first type of crushing blade and the second type of crushing blade may be a triangular blade, a circular arc blade, a polygonal blade, a helical gear, a conical gear, a spur gear, a helical gear, a herringbone gear, respectively. In other examples, the first type of spacer and the second type of spacer may be circular rings or square rings, respectively.

In some examples, as shown in fig. 2, the feeding portion 12 may include a first motor 123 and a second motor 124. The first motor 123 may be used to drive the first shaft core 121, and the second motor 124 may be used to drive the second shaft core 122. In some examples, in the feeding portion 12, the first shaft core 121 may be independently driven by a first motor 123 and the second shaft core 122 may be independently driven by a second motor 124.

In some examples, the first motor 123 and the second motor 124 may be servo motors or variable frequency motors. In other examples, the first motor 123 and the second motor 124 may be disposed outside or inside the fixing frame 125.

In some examples, the dosing section 12 may include a transmission module. In other examples, the transmission module may be disposed at the ends of the first and second mandrels 121, 122. In some examples, the transmission module may be fixedly connected with the first and second mandrels 121, 122.

In some examples, the transmission module may include a drive gear and a driven gear. Thus, the rotation of the first and second cores 121 and 122 can be controlled by the driving gear and the driven gear. In some examples, the driving gear and the driven gear may rotate in opposite directions. For example, the drive gear may rotate in a clockwise direction and the driven gear may rotate in a counterclockwise direction. In other examples, the driving gear and the driven gear may be the same size or different sizes.

In some examples, the transmission module may include a first drive gear, a second drive gear, a first driven gear 126, and a second driven gear 127. In addition, a first driving gear may be connected to the first motor 123, and a first driven gear 126 may be connected to the first shaft core 121 (see fig. 3). A second driving gear may be coupled to the second motor 124 and a second driven gear 127 may be coupled to the second hub 122 (see fig. 3).

In some examples, the first driving gear and the first driven gear 126 may mesh with each other. In addition, the second driving gear and the second driven gear 127 may be engaged with each other.
