Description

Technical Field

[0001] The utility model relates to the technical field of automatic dispensing of traditional Chinese medicine granules, in particular to a carrier box rotating mechanism used in traditional Chinese medicine granule dispensing equipment. Background Art

[0002] Although the automated Chinese medicine granule dispensing equipment can replace the manual preparation of Chinese medicine, it still needs to rely on manual operation in the process of taking and placing the medicine bottle. For example, when dispensing Chinese medicine, the staff needs to take the medicine bottle from the medicine cabinet, then move to the vicinity of the dispensing equipment, weigh the medicine bottle and place it at the dispensing station of the dispensing equipment, and then the dispensing equipment automatically completes the dispensing, packaging and other actions. After completion, the staff also needs to take the medicine bottle from the dispensing station, then move to the medicine cabinet, and put the medicine bottle back to the original storage position. Among them, the structure of the above-mentioned medicine cabinet can be found in the Chinese patent with publication number CN109567429A. The layout of the medicine cabinet is a planar array layout, and the above-mentioned dispensing equipment can be found in the Chinese patent with publication number CN117302608A.

[0003] It can be seen that in the above process, although the actions of dispensing and packaging are completed automatically, the process of taking and placing the medicine bottles is not automated and still needs to be completed manually.

[0004] In this regard, the applicant believes that it is necessary to improve the automation level of the entire operation process and automate the process of taking and placing medicine bottles to further save labor and improve work efficiency. Therefore, the applicant designed a dispensing system that can automate the entire process. Utility Model Content

[0005] In the fully automated dispensing system designed by the applicant, the dispensing system includes a medicine cabinet and dispensing equipment, wherein the medicine cabinet is enclosed, and the dispensing equipment is arranged in the enclosed medicine cabinet. When dispensing the Chinese medicine granules, a robot grabs the medicine bottle from the inside of the medicine cabinet, and then places it on the weighing station or the dispensing station of the dispensing equipment to execute the weighing step and the quantitative unloading step of the medicine bottle. Among them, in the dispensing equipment, the packaging bag used for medicine needs to be moved in a circular path by the carrying box, so that the packaging bag passes through each dispensing station in turn, and the medicine is dispensed as needed, and finally the packaged Chinese medicine formula granules are obtained after the bag is sealed and unloaded.

[0006] Among them, when the carrier box moves in a circular path, the rotation radius is large. If the design is improper, the operating load will be relatively large, and the area enclosed by the circular path must also reserve installation space for other mechanisms or devices, such as weighing devices, manipulator devices, etc. Therefore, how to design a reasonable circular motion mechanism is a problem that the applicant needs to consider. In this regard, the technical problem to be solved by the utility model is how to provide a reasonable circular motion mechanism that can smoothly move the carrier box in a circular path and reserve space for the installation of other mechanisms or devices.

[0007] The technical solution adopted by the utility model to solve the technical problem is: to provide a carrier box rotating mechanism used in a Chinese medicine granule dispensing device, comprising:

[0008] The first synchronous belt is arranged in a ring shape;

[0009] A carrying box, fixed on the outer side of the first synchronous belt;

[0010] A first driving wheel, used to drive the first synchronous belt to perform a rotary motion;

[0011] A first motor, used to drive the first driving wheel to rotate around its own axis;

[0012] A plurality of first driven wheels are sequentially arranged on the inner side of the first synchronous belt along a circular path, and are used to support the first synchronous belt so that it maintains the circular arrangement state, and can rotate around its own axis as the first synchronous belt moves.

[0013] Preferably, the inner side of the first synchronous belt includes a tooth surface area and a plane area; the tooth surface area has a circle of belt teeth arranged in sequence at equal intervals; the plane area is an annular smooth surface;

[0014] Among them, the first driving wheel is a synchronous wheel, which meshes with the belt teeth in the tooth surface area through the gear teeth on its outer surface to drive the first synchronous belt to perform the rotational motion; the outer surface of the first driven wheel is provided with a first step surface with an annular protrusion, and the first driven wheel supports the first synchronous belt and rotates around its own axis only through the fit between the first step surface and the smooth surface.

[0015] Preferably, the number of the smooth surfaces is two and they are distributed on the upper and lower sides of the belt teeth; the outer surface of the first driven wheel is provided with two circles of annular raised first step surfaces, and the two circles of the first step surfaces are respectively fitted with the two smooth surfaces.

[0016] Preferably, the first driven wheel is further provided with a circle of annular raised second step surface in the middle of two circles of the first step surface, and the outer diameter of the second step surface is smaller than the outer diameter of the first step surface.

[0017] Preferably, the first synchronous belt comprises first sub-belt teeth with reserved mounting holes, and the mounting holes are penetrated by screws for connecting the carrying box, so that the carrying box is fixed correspondingly to the first sub-belt teeth.

[0018] Preferably, the carrying box is equipped with a limiting card block, and the carrying box is provided with a limiting groove adapted to the limiting card block, the limiting card block is clamped in the limiting groove, and the limiting card block is fixed to the carrying box on the one hand, and is also fixed to the first sub-belt tooth through the screw on the other hand.

[0019] Preferably, the outer surface of the first driven wheel is not provided with gear teeth.

[0020] Preferably, the carrier box rotating mechanism further includes a plurality of limit baffles;

[0021] The plurality of limit baffles are arranged in sequence along the first synchronous belt, wherein a limit slot is provided on the upper and lower sides of each of the limit baffles;

[0022] The smooth surfaces on the upper and lower sides of the first synchronous belt are respectively inserted into the limit slots on the upper and lower sides of each limit baffle, and the smooth surfaces can move along the extension direction of the limit slots.

[0023] Preferably, the carrier box rotating mechanism further includes a rotating base;

[0024] The first driven wheel and the limit baffle are both installed on the rotary base.

[0025] Preferably, the number of the carrier boxes is not less than 25, and the carrier boxes are fixed on the outer side of the first synchronous belt in sequence at predetermined intervals along the annular path.

[0026] The working principle of the carrier box rotating mechanism of the utility model is as follows:

[0027] When the first motor is started, it can drive the first driving wheel to rotate, and the rotation of the first driving wheel will drive the first synchronous belt to perform a rotary motion. Since the carrier box is fixed on the outside of the first synchronous belt, the carrier box will perform a rotary motion with the first synchronous belt. During the movement, since the packaging bag is contained in the carrier box, when the packaging bag moves to the bottom of the dispensing station, the first motor can be suspended, and then the corresponding control component controls the medicine bottle pre-installed on the adjustment station to quantitatively discharge the medicine, so that the medicine particles are transferred into the packaging bag as needed. If multiple medicine particles need to be transferred into the packaging bag, the first motor can control the packaging bag to stay at multiple dispensing stations in turn, and then the medicine bottles containing different medicine particles are quantitatively transferred into the packaging bag. The required medicine particles, finally, the first motor drives the adjusted packaging bag to move to the bag sealing station, and the corresponding mechanism completes the bag sealing and bag discharging actions, and finally the packaged Chinese medicine formula granules are obtained.

[0028] In the utility model, the first driven wheel and the first synchronous belt are matched with each other only by the mutual contact of the first step surface and the smooth surface. There is no mutual meshing of teeth between the first driven wheel and the first synchronous belt. Such matching mode can support the first synchronous belt to maintain its ring shape on the one hand, and reduce the number of meshing teeth on the other hand, thereby avoiding the large abnormal noise caused by the mutual meshing of too many teeth and the problem of excessive motion load caused by the mutual meshing of too many teeth.

[0029] Adding a limit baffle can keep the first synchronous belt vertical at all times, prevent the first synchronous belt from shaking inside and outside during operation, and prevent the first synchronous belt from falling downward under the gravity of the carrier box.

[0030] It can be seen that the design of the carrier box rotating mechanism of the utility model is relatively reasonable. The first synchronous belt can smoothly carry the carrier box to move in a circular path, and can reserve a large enough space in the middle to facilitate the installation of other mechanisms or devices.

[0036] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0037] In the fully automated dispensing system designed by the applicant, the packaging bags used to hold medicines need to be carried by a carrier box and moved in a circular path, so that the packaging bags pass through each dispensing station in turn, and the medicines are dispensed as needed, and finally the packaged Chinese medicine formula granules are obtained after the bags are sealed and unpacked.

[0038] Among them, when the carrier box moves in a circular path, the rotation radius is large. If the design is not appropriate, the operating load will be relatively large, and space must be reserved in the area enclosed by the circular path for the installation of other mechanisms or devices, such as weighing devices, manipulator devices, etc.

[0039] In this regard, the applicant has specially designed a carrier box rotating mechanism for use in a Chinese medicine granule dispensing device, such as Figure 1 and Figure 2 As shown, the carrier box rotating mechanism includes a first synchronous belt c1, a carrier box c2, a first driving wheel c3, a first motor c4, a plurality of first driven wheels c5 and a rotating base c8.

[0040] The first synchronous belt c1 is arranged in a ring shape.

[0041] There are a plurality of the carrier boxes c2 , and the plurality of carrier boxes c2 are fixed on the outer side of the first synchronous belt c1 in sequence at a certain interval along the circular path.

[0042] The first driving wheel c3 meshes with the belt teeth c11 on the inner side of the first synchronous belt c1 through the gear teeth on the outer surface, so as to drive the first synchronous belt c1 to perform a rotational motion.

[0043] The first motor c4 is connected to the driving wheel c3 via a reducer, and is used to drive the first driving wheel c3 to rotate around its own axis.

[0044] The plurality of first driven wheels c5 are sequentially arranged along a circular path on the inner side of the first synchronous belt c1 to support the first synchronous belt c1 to maintain the circular arrangement state, and the first driven wheel c5 can rotate around its own axis as the first synchronous belt c1 rotates.

[0045] The rotatable base c8 is arranged below the first synchronous belt c1, and the first motor c4 and the first driven wheel c5 are both mounted on the rotatable base c8, wherein the first driven wheel c5 is rotatably mounted on the rotatable base c8 via a bearing.

[0046] The annular arrangement of the first synchronous belt c1 is not limited to a regular circular ring structure, but may also be a partially linear structure but generally annular in shape as a whole.

[0047] Preferably, the number of the carrier boxes c2 is not less than 25. The number of the carrier boxes c2 illustrated in the figure is 36.

[0048] The working principle of the above-mentioned carrier box rotating mechanism is as follows:

[0049] When the first motor c4 is started, it can drive the first driving wheel c3 to rotate, and the rotation of the first driving wheel c3 will drive the first synchronous belt c1 to perform a rotary motion. Since each carrier box c2 is fixed on the outside of the first synchronous belt c1, each carrier box c2 will perform a rotary motion together with the first synchronous belt c1. During the motion, since the packaging bag is contained in the carrier box c2, when the packaging bag moves to the bottom of the dispensing station, the first motor c4 can stop working, and then the corresponding control component controls the medicine bottle pre-placed on the adjustment station to quantitatively dispense medicine, so that the medicine particles are transferred into the packaging bag as needed. If multiple medicine particles need to be transferred into the packaging bag, the first motor c4 can control the packaging bag to stay at multiple dispensing stations in turn, and then the medicine bottles containing different medicine particles quantitatively transfer the required medicine particles into the packaging bag. Finally, the first motor c4 drives the adjusted packaging bag to move to the bag sealing station, and the corresponding mechanism completes the bag sealing and bag discharging actions, and finally the packaged Chinese medicine formula particles are obtained;

[0050] In the above process, when the first synchronous belt c1 performs a rotational motion, each first driven wheel c5 plays a supporting role on the inner side of the first synchronous belt c1, so that the first synchronous belt c1 can be tightened to maintain a ring state.

[0051] Previously, a turntable is usually used to drive the carrier box c2 to rotate, such as the Chinese patent with publication number CN117302608A. However, in the present invention, the number of carrier boxes c2 is usually larger, so the rotation radius is usually larger. If the turntable is still used to drive the carrier box c2 to move, the radius of the turntable will be greatly increased, resulting in a relatively large load on the motor and a relatively high cost. At the same time, it is difficult to reserve enough installation space in the middle area of ​​the turntable for components such as weighing devices and manipulator devices.

[0052] Therefore, the utility model uses a synchronous belt to drive the carrier box c2 to rotate, so that the motor does not need to bear a large load and the cost is relatively low. At the same time, the area enclosed by the synchronous belt can also be used to install components such as weighing devices and manipulator devices.

[0053] However, in the above technical solution, if the existing synchronous belt structure and operation mode are directly used to drive the carrier box c2 to perform a rotary motion, each driven wheel supporting the synchronous belt needs to be meshed with the synchronous belt. However, in such a structural form, too many meshing teeth will inevitably cause a large abnormal noise when the rotary mechanism is running. At the same time, too many meshing teeth will also increase the running load of the motor, and may even cause a step loss. In order to improve the above situation, in some embodiments, the following settings are also made:

[0054] A plane area is divided on the inner side of the first synchronous belt c1, so that the inner side of the first synchronous belt c1 has both a tooth surface area and a plane area; see Figure 2 The tooth surface area is arranged with a circle of belt teeth c11 at equal intervals, and the plane area is an annular smooth surface c12. The number of the smooth surface c12 is two circles and they are distributed on the upper and lower sides of the belt teeth c11;

[0055] See also Figure 2 The outer surface of the first driven wheel c5 is not provided with gear teeth, but is provided with two circles of annular raised first step surfaces c51, and the two circles of first step surfaces c51 are respectively in contact with the two smooth surfaces c12. Therefore, the first driven wheel c5 supports the first synchronous belt c1 and rotates around its own axis line only by the two circles of first step surfaces c51 and the two circles of smooth surfaces c12 respectively in contact with each other.

[0056] In the above structure, the cooperation mode of the driven wheel and the synchronous belt is very different from the existing conventional cooperation mode, that is, the first driven wheel c5 and the first synchronous belt c1 are not meshed with each other, but the cooperation between the two is achieved by the fit between the first step surface c51 and the smooth surface c12. Such a cooperation mode can not only support the first synchronous belt c1 to maintain its ring shape, but also reduce the number of meshing teeth on the other hand, thereby avoiding the large abnormal noise caused by the meshing of too many teeth, and the problem of excessive motion load caused by the meshing of too many teeth. That is, if all the first driven wheels c5 are meshed with the belt teeth of the first synchronous belt c1 through the wheel teeth, then when the first synchronous belt c1 is running, the meshing of many first driven wheels c5 and the first synchronous belt c1 will produce a large abnormal noise, and at the same time increase the running resistance of the first synchronous belt c1, resulting in the first motor c4 being difficult to drive the first synchronous belt c1 to run smoothly, and even losing steps during operation.

[0057] Of course, in other embodiments, the layout of the belt teeth c11 and the smooth surface c12 can also be in other forms, for example, the number of the smooth surface c12 is one circle, and the number of the belt teeth c11 is two circles and they are arranged on the upper and lower sides of the smooth surface c12 respectively (that is, it is equivalent to setting the smooth surface c12 in the middle of the first synchronous belt c1, and dividing the original one circle of belt teeth c11 into upper and lower halves); at the same time, the structure of the first driven wheel c5 is adapted thereto, and a first step surface c51 is set in the middle and fits with the smooth surface c12; thereby, the support for the first synchronous belt c1 and the rotation around its own axis line with the movement of the first synchronous belt c1 can also be achieved. However, the supporting effect of this structure on the first synchronous belt c1 is not as good as the aforementioned structure, so the structural form in which the aforementioned two smooth surfaces c12 are distributed on the upper and lower sides of the belt teeth c11 is usually selected.

[0058] Furthermore, in some embodiments, the first driven wheel c5 is provided with a second annular raised step surface c52 in the middle of the upper and lower first step surfaces c51, and the outer diameter of the second step surface c52 is smaller than the outer diameter of the first step surface c51. The purpose of providing the second step surface c52 is that since the synchronous belt may have a concave deformation in the middle area after running for a long time, the second step surface c52 is added to the middle part of the first driven wheel c5 to play a supporting role, supporting the first synchronous belt c1 with a concave deformation in the middle area after long-term operation.

[0059] However, it should be noted that the outer diameter of the second step surface c52 needs to be smaller than the outer diameter of the first step surface c51. Under normal circumstances, the second step surface c52 will not contact the first synchronous belt c1 (including not contacting the belt teeth c11 of the first synchronous belt c1). Only when the middle area of ​​the first synchronous belt c1 undergoes a concave deformation, the second step surface c52 is likely to contact the first synchronous belt c1 to support the first synchronous belt c1.

[0060] In some embodiments, see Figure 2 The belt teeth c11 include first sub-belt teeth c111 with reserved mounting holes c1111, and the mounting holes c1111 are penetrated by screws to connect the carrier box c2, so that the carrier box c2 is fixed correspondingly to the first sub-belt teeth c111.

[0061] Preferably, the first sub-belt teeth c111 are made of steel and are independent entities that can be removed from the first synchronous belt c1. In addition, except for the first sub-belt teeth c111, the remaining belt teeth c11 are all second sub-belt teeth c112, and the second sub-belt teeth c112 are integrally formed on the first synchronous belt c1.

[0062] It can be seen that the first synchronous belt c1 in the utility model is a non-standard customized synchronous belt. When the manufacturer makes the synchronous belt, it is necessary not only to reserve smooth surfaces c12 on the upper and lower sides of the belt teeth c11, but also to reserve a blank area at a certain distance to reserve space for the installation of the first sub-belt teeth c111, so that when the carrier box c2 is installed later, the staff can install the first sub-belt teeth c111 by themselves.

[0063] For further information, see Figure 4 The carrying box c2 is provided with a limit block c71 and a positioning rod c72, wherein the positioning rod c72 is vertically fixed to one side of the limit block c71 by screws. The carrying box c2 is provided with a limit groove c21 adapted to the limit block c71.

[0064] When the carrier box c2 is installed on the first synchronous belt c1, the process is roughly as follows:

[0065] First, use screws to fix the first sub-belt tooth c111 and the limit block c71. When fixed, the first sub-belt tooth c111 and the limit block c71 are respectively located on the inner and outer sides of the first synchronous belt c1. The screws pass through the mounting hole c1111 and the belt body of the first synchronous belt c1 and are tightened with the limit block c71, thereby achieving the fixation of the first sub-belt tooth c111 and the limit block c71; then, install the carrier box c2. During installation, allow the limit block c71 to be inserted into the limit groove c21 of the carrier box c2. When inserted, allow the positioning rod c72 to pass through the positioning reserved hole c22 on the carrier box c2, and then use screws to lock the positioning rod c72 so that the limit block c71 is fixedly locked in the limit groove c21 of the carrier box c2.

[0066] In the above-mentioned fixing method, the limit block c71 is fixed to the first synchronous belt c1, and the carrying box c2 is fixed to the limit block c71, and the limit block c71 is also stuck in the limit groove c21 of the carrying box c2. The positioning rod c72 and the limit groove c21 jointly play a limiting role, which can prevent the carrying box c2 from shaking left and right or tilting left and right.

[0067] In some embodiments, see Figure 1 and Figure 2 The carrier box rotating mechanism further includes a plurality of limit baffles c6, which are sequentially arranged along the first synchronous belt c1 and fixed to the rotating base c8, wherein the limit baffles c6 are arranged between adjacent first driven wheels c5. Figure 3 A limit slot c61 is provided on the upper and lower sides of each limit baffle c6, and the smooth surfaces c12 on the upper and lower sides of the first synchronous belt c1 are respectively inserted into the limit slots c61 on the upper and lower sides of each limit baffle c6. At the same time, the smooth surface c12 can move smoothly in the limit slot c61 along the extension direction of the limit slot c61.

[0068] Preferably, see Figure 3 The starting end and the tail end of the limit slot c61 are both provided with a guide inclined surface c611 with an enlarged diameter to ensure that the smooth surface c12 of the first synchronous belt c1 can smoothly enter the limit slot c61 to reduce wear.

[0069] The purpose of adding the limit baffle c6 is to limit the first synchronous belt c1 to keep it vertical, so as to prevent the first synchronous belt c1 from shaking inside and outside during operation, and to prevent the first synchronous belt c1 from falling downward under the gravity of the carrier box c2.

[0070] It should be noted that, although the first synchronous belt c1 between two adjacent first driven wheels c5 is supported by the two first driven wheels c5 and is in a straight line, the shape enclosed by the first synchronous belt c1 is still roughly annular as a whole. Figure 1 In the figure, the limit baffle c6 on the right is set to be relatively long, and its purpose is to facilitate the cooperation with the bag making mechanism and the bag sealing and discharging mechanism. Specifically, the two first driven wheels c5 on the upper right side are spaced relatively large (the corresponding limit baffle c6 is also relatively long), which allows the carrier box c2 to make a linear motion in this area. During the linear motion, the carrier box c2 first brings the adjusted packaging bags to the bag sealing station, and the bag sealing and discharging mechanism first seals the top of the packaging bags, and then transmits the sealed packaging bags to the designated position. After that, the first synchronous belt c1 moves the empty carrier box c2 in a straight line to the bag making station, and the bag making mechanism places the prepared packaging bags in the carrier box c2. Subsequently, the first synchronous belt c1 continues to move along the circular path with the carrier box c2 carrying the packaging bags to complete the subsequent steps of adjusting and adding medicines.

[0071] In summary, the design of the carrier box rotating mechanism of the present invention is relatively reasonable. The first synchronous belt c1 can smoothly carry each carrier box c2 to move in a circular path, and can reserve a large enough space in the middle to facilitate the installation of other mechanisms or devices.

[0072] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
