Description

Technical Field

[0001] This invention relates to the field of drug dispensing technology, and in particular to a drug weighing and dispensing device. Background Technology

[0002] The pharmaceutical production line includes a drug repackaging process, which involves dividing the drug into smaller portions according to a specified amount to facilitate subsequent drug packaging operations.

[0003] Currently, the drug packaging process mostly uses manual weighing and dispensing. However, this method is not only inefficient, labor-intensive, and costly, but also difficult to guarantee high weighing accuracy and uniformity due to human factors. As a result, the quality of drug packaging is poor and cannot meet production requirements.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] To overcome the above-mentioned defects, the present invention provides a drug weighing and dispensing device with a simple and reasonable structure, and a high degree of integration and automation. It not only greatly improves processing efficiency and reduces labor intensity and labor costs, but also enables precise control of the weight of drug particles, ensuring the quality of weighing and dispensing operations.

[0006] The technical solution adopted by this invention to solve its technical problem is: a weighing and dispensing device for medicines, comprising:

[0007] The feeding mechanism is equipped with a funnel for holding medicine granules and a sealing device that can close or open the discharge port of the funnel;

[0008] The dispensing mechanism is provided with a flow channel that can receive the drug particles discharged through the feed port of the funnel and a drive A that can drive the flow channel to vibrate. The flow channel can be vibrated to transport the drug particles falling into it along the conveying direction of the flow channel, and the width of the flow channel gradually decreases along its conveying direction.

[0009] The weighing mechanism includes a weighing component, a receiving component disposed on the weighing component and used to support the receiving container, and a driving component B capable of driving the weighing component and the receiving component together to move closer to or further away from the outlet of the flow channel. When the receiving component and the receiving container on it are close to the outlet of the flow channel, the drug particles discharged through the outlet of the flow channel can fall into the receiving container.

[0010] The blanking mechanism is provided with a plurality of material taking portions and a driving member C connected with the material taking portions. The driving member C can drive the plurality of material taking portions to move to the upper and lower container positions in sequence, so as to realize that the material taking portions move the empty medicine receiving containers to the material receiving member and take the full medicine receiving containers to the next work station. When one of the material taking portions moves to the next work station with the full medicine receiving container, another material taking portion can move the empty medicine receiving container to the material receiving member.

[0011] As a further improvement of the present application, the weighing member is located below the discharge port of the flow channel, the material receiving member is arranged on the upper side of the weighing member, and the material receiving member is an integral structure with a plurality of clamping fingers.

[0012] The driving member B is connected with the weighing member and can drive the weighing member and the material receiving member thereon to move up and down. When the driving member B drives the weighing member and the material receiving member to move upward, the material receiving member can move through the material taking portion at the upper and lower container position to take the medicine receiving container arranged on the material taking portion. Then the driving member B drives the weighing member, the material receiving member and the medicine receiving container to continue moving upward until the medicine receiving container is located at the discharge port of the flow channel to receive the medicine particles discharged through the discharge port of the flow channel. When the driving member B drives the weighing member, the material receiving member and the medicine receiving container to move downward, the material receiving member moves through the material taking portion while the medicine receiving container freely falls on the material taking portion.

[0013] As a further improvement of the present application, each material taking portion is provided with a receiving groove for receiving the medicine receiving container and a position avoiding hole slot arranged in the receiving groove and allowing the material receiving member to freely pass through.

[0014] As a further improvement of the present application, the medicine receiving container adopts a bowl-shaped container. The clamping fingers are arranged in four and are L-shaped transversely arranged. The four clamping fingers are integrally connected into a cross-shaped structure.

[0015] The shape of the position avoiding hole slot matches the cross-shaped structure.

[0016] As a further improvement of the present application, the weighing member adopts an electronic balance. An installation seat is fixedly arranged on the upper side of the weighing member. The material receiving member is fixedly arranged on the installation seat. A space for avoiding the material taking portion is formed between the material receiving member and the installation seat.

[0017] The driving member B includes a fixing plate for receiving the weighing member and a cylinder A connected with the fixing plate and capable of driving the fixing plate to move up and down.

[0018] As a further improvement of the present application, the blanking mechanism is further provided with a horizontally placed base plate, which is divided into a plurality of receiving areas, and each of the receiving areas is surrounded by a retaining wall.

[0019] The driving member C comprises a cylinder B, which is connected to the base plate and can drive the base plate to rotate horizontally, so as to move the plurality of material taking parts to the upper and lower container positions in sequence.

[0020] As a further improvement of the present application, the flow channel comprises a first flow channel and a second flow channel connected to the discharge port of the first flow channel, the width of the first flow channel is greater than the width of the second flow channel, and the downward projection of the discharge port of the first flow channel completely falls into the first flow channel, and the downward projection of the discharge port of the second flow channel completely falls into the medicine receiving container placed on the weighing member.

[0021] The driving member A comprises two vibrators to provide vibration force to the first flow channel and the second flow channel, respectively.

[0022] As a further improvement of the present application, the medicine feeding mechanism is further provided with an outer frame for supporting and fixing the hopper.

[0023] The sealing member comprises a sealing plate located below the discharge port of the hopper and slidingly arranged in the outer frame, and a handle provided on the sealing plate and held by an operator, when an external force is applied to the handle, the sealing plate can be driven to open or close the discharge port of the hopper.

[0024] As a further improvement of the present application, the medicine feeding mechanism is further provided with a protective member, which is a hollow cylindrical structure with open upper and lower ends, the protective member is elastically and coaxially sleeved outside the discharge port of the hopper, and when the sealing plate closes the discharge port of the hopper, the lower end of the protective member is elastically tightly attached to the sealing plate.

[0025] As a further improvement of the present application, the position of the medicine receiving container close to the discharge port of the flow channel is defined as the medicine receiving position.

[0026] The medicine feeding, weighing and dispensing equipment is further provided with a dehumidification mechanism, which comprises a gas source supply device for supplying dry gas and a gas blowing nozzle in communication with the gas source supply device, and the gas blowing nozzle is arranged at the medicine receiving position.

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0039] Embodiment 1

[0040] The present embodiment 1 provides a medicine feeding, weighing and distributing equipment for realizing automatic medicine feeding, distributing, weighing and discharging operations.

[0041] Please refer to the attached drawings Figure 1 to the attached drawings Figure 8As shown, the medicine feeding, weighing and dispensing device provided by the present embodiment mainly comprises a medicine feeding mechanism 1, a medicine dispensing mechanism 2, a weighing mechanism 3 and a discharging mechanism 4. The medicine feeding mechanism 1 is provided with a hopper 10 for containing medicine particles and a sealing member 11 capable of sealing or opening the discharging port of the hopper 10. The medicine dispensing mechanism 2 is provided with a flow channel 20 capable of receiving the medicine particles discharged from the discharging port of the hopper 10 and a driving member A capable of driving the flow channel 20 to vibrate. The flow channel 20 is capable of conveying the medicine particles falling into the flow channel 20 along the conveying direction of the flow channel 20 by vibration. The width of the flow channel 20 gradually decreases along the conveying direction, which can improve the dispensing accuracy of the medicine dispensing mechanism 2 and realize accurate dispensing. The weighing mechanism 3 is provided with a weighing member 30, a receiving member 32 arranged on the weighing member 30 and used for receiving a medicine receiving container 31, and a driving member B capable of driving the weighing member 30 and the receiving member 32 to move close to or away from the discharging port of the flow channel 20. When the receiving member 32 and the medicine receiving container 31 thereon are close to the discharging port of the flow channel 20, the medicine particles discharged from the discharging port of the flow channel 20 can fall into the medicine receiving container 31. The discharging mechanism 4 is provided with a plurality of material taking portions 40 and a driving member C connected with the material taking portions 40. The driving member C is capable of driving the plurality of material taking portions 40 to move to the upper and lower container positions in sequence, so as to realize the movement of the empty medicine receiving container 31 to the receiving member 32 by the material taking portion 40 and the movement of the medicine receiving container 31 full of medicine particles to the next station. When one of the material taking portions 40 moves to the next station together with the medicine receiving container 31 full of medicine particles, another material taking portion 40 can move the empty medicine receiving container 31 to the receiving member 32, so as to realize the non-stop operation of the whole device.

[0042] According to the above general description of the structure of the medicine feeding, weighing and dispensing device, it can be known that the processing method of the medicine feeding, weighing and dispensing device is as follows (briefly described):

[0043] S1: manually or by a feeding device (such as a belt conveyor or a vibrating disc feeder) to put the medicine particles into the hopper 10. The volume of the hopper 10 is determined according to the production requirements, which is not limited in the present embodiment.

[0044] S2: manually or by a mechanical hand to operate the sealing member 11, so as to open the discharging port of the hopper 10. At this time, the medicine particles will be discharged from the discharging port of the hopper 10 and fall onto the flow channel 20. Correspondingly, under the action of the vibration of the flow channel 20, the medicine particles falling into the flow channel 20 will be conveyed along the conveying direction of the flow channel 20.

[0045] S3: the first said material taking part 40 is moved to the upper and lower container position under the drive of the driving member C, and an empty said medicine receiving container 31 is transferred to the said material receiving member 32; then, the driving member B drives the said weighing member 30, the said material receiving member 32 and the said medicine receiving container 31 to move close to the discharge port of the said flow channel 20, so that the medicine grains discharged from the discharge port of the said flow channel 20 can fall into the said medicine receiving container 31;

[0046] When the said medicine receiving container 31 is full of medicine grains (here, "full of medicine grains" means that the said medicine receiving container 31 is full of medicine grains with a specified weight), the driving member B drives the said weighing member 30, the said material receiving member 32 and the said medicine receiving container 31 to move away from the discharge port of the said flow channel 20 to a set distance;

[0047] S4: the first said material taking part 40 takes away the said medicine receiving container 31 full of medicine grains to the next work station, and correspondingly, the second said material taking part 40 is moved to the upper and lower container position under the drive of the driving member C, so as to transfer an empty said medicine receiving container 31 to the said material receiving member 32;

[0048] Then, the above-mentioned S3 and S4 are repeated until the medicine weighing and dispensing operation of all medicine grains is completed.

[0049] Supplementary explanation: ①The width of the said flow channel 20 and the vibration mode are controlled, so that when the said medicine receiving container 31 is replaced (i.e. the said material taking part 40 takes away the said medicine receiving container 31 full of medicine grains and then transfers an empty said medicine receiving container 31 to the said weighing member 30), the medicine grains discharged from the discharge port of the said flow channel 20 will not leak outside. The specific control method of the said flow channel 20 is described below. ②In actual production, a mechanical hand is arranged in the next work station, which is mainly used for medicine pouring operation of the said medicine receiving container 31 full of medicine grains, i.e. when the said medicine receiving container 31 full of medicine grains is transferred to the next work station by the said material taking part 40, the mechanical hand takes the said medicine receiving container 31 from the said material taking part 40 and then overturns the said medicine receiving container 31 to pour the medicine grains into a specified container or equipment. Moreover, after the mechanical hand completes the medicine pouring operation, the mechanical hand also places an empty said medicine receiving container 31 on the said material taking part 40 which is empty (i.e. not carrying the said medicine receiving container), so as to realize the recycling of the said medicine receiving container 31. Further explanation: the next work station and the mechanical hand therein do not belong to the protection points of the present application, and the mechanical hand and the actions and functions that can be realized by the mechanical hand are common technical means in the field of automatic processing, which are easy to understand and realize, so they are not described in detail here.

[0050] From the above, compared with the prior art, the medicine feeding, weighing and dispensing equipment integrates the processes of "automatic medicine feeding", "automatic medicine dispensing", "automatic weighing" and "automatic medicine dispensing", has high integration and automation, greatly improves the processing efficiency, reduces the labor intensity and labor cost, can accurately control the weight of medicine particles, and ensures the quality of the weighing and dispensing operation.

[0051] The specific structure of the medicine feeding, weighing and dispensing equipment will be described in detail below.

[0052] First, the weighing mechanism 3 and the discharging mechanism 4.

[0053] Please continue to refer to the accompanying Figure 2 , the accompanying Figure 6 to the accompanying Figure 8 , in the weighing mechanism 3 provided in the embodiment, the weighing member 30 is located below the discharge port of the flow channel 20, the receiving member 32 is arranged on the upper side of the weighing member 30, and the receiving member 32 is an integral structure having a plurality of clamping fingers 320; the driving member B is connected with the weighing member 30 and can drive the weighing member 30 and the receiving member 32 thereon to move up and down together; and when the driving member B drives the weighing member 30 and the receiving member 32 to move upward together, the receiving member 32 can move through the material taking part 40 located at the position of the upper and lower container to take away the medicine container 31 arranged on the material taking part 40; then the driving member B drives the weighing member 30, the receiving member 32 and the medicine container 31 to continue moving upward, until the medicine container 31 is located at the discharge port of the flow channel 20 (specifically, directly below the discharge port of the flow channel 20) to receive the medicine particles discharged through the discharge port of the flow channel 20; when the driving member B drives the weighing member 30, the receiving member 32 and the medicine container 31 to move downward together, the receiving member 32 can move through the material taking part 40 at the same time, and the medicine container 31 can freely fall on the material taking part 40.

[0054] Understandably, the operation of the material-picking unit 40 in this embodiment for picking up and placing the medicine receiving container 31 is essentially achieved through the coordinated cooperation of the material-picking unit 40 and the weighing mechanism 3. Specifically: ① When the material-picking unit 40 needs to transfer an empty medicine receiving container 31 to the weighing component 30, the material-picking unit 40 first moves along with the empty medicine receiving container 31 to the upper and lower container position under the drive of the drive component C. This upper and lower container position is located above the initial position of the receiving component 32, that is, the upper and lower container position is arranged in the path of the upper and lower movement of the receiving component 32; then the drive component B drives the weighing component 30 and the receiving component 32 to move upwards together until the receiving component 32 passes through the material-picking unit 40. At that time, the empty medicine receiving container 31 falls onto the receiving component 32, thus realizing the "placing the medicine receiving container" operation of the material-picking unit 40; after completing the above operation... The driving component B drives the weighing component 30, the receiving component 32, and the receiving container 31 to continue moving upwards until the receiving container 31 is located at the outlet of the flow channel 20 to receive the drug particles discharged through the outlet of the flow channel 20; ② When the receiving container 31 is full of drug particles and needs to be taken away by the picking part 40, the driving component B drives the weighing component 30, the receiving component 32, and the receiving container 31 to move downwards until the receiving component 32 moves through the picking part 40. At that time, the receiving container 31, which is full of drug particles, falls freely onto the picking part 40; then, the picking part 40, driven by the driving component C, moves together with the receiving container 31, which is full of drug particles, to the next station.

[0055] Further preferably, in order to coordinate with the movement of the receiving member 32 and to be able to receive the medicine receiving container 31, in the feeding mechanism 4 provided in this embodiment, the material taking part 40 preferably adopts the following structure: Please refer to the appendix. Figure 8 As shown, each of the feeding sections 40 is provided with a receiving groove for receiving the medicine container 31 and a clearance slot 401 provided in the receiving groove for the receiving member 32 to pass through freely. It can be understood that the shape of the clearance slot 401 matches the shape of the receiving member 32 so that the receiving member 32 can pass through freely; and the receiving groove can also hold the medicine container 31 to interrupt the medicine container 31 from continuing to move downward with the receiving member 32.

[0056] More preferably, the medicine receiving container 31 is a bowl-shaped container, which can be round or oval, etc., and this patent does not impose too many restrictions. Furthermore, based on the shape of the medicine receiving container 31 and to ensure stability when housing the medicine receiving container 31, in this embodiment, the gripping fingers 320 are configured as four, all horizontally placed in an L-shape, and the four gripping fingers 320 are integrally connected to form a cross-shaped structure (see appendix for details). Figure 6 and attached Figure 7 (As shown). Accordingly, the shape of the clearance slot 401 matches the cross-shaped structure.

[0057] Furthermore, in the weighing mechanism 3 provided in this embodiment, it is further preferred that the weighing component 30 is an electronic balance, which can communicate with the controller to further improve the accuracy of the equipment's weighing and dispensing operations.

[0058] The structure for setting the receiving component 32 on the weighing component 30 is as follows: Please refer to the appendix. Figure 6 and attached Figure 7 As shown, a mounting base 33 is detachably fixed to the upper side of the weighing component 30 by fasteners, and the receiving component 32 is also detachably fixed to the mounting base 33 by fasteners. Furthermore, a space is formed between the receiving component 32 and the mounting base 33 to avoid interference with the material taking part 40 when the receiving component 32, the mounting base 33, and the weighing component 30 move up and down.

[0059] Please continue to refer to the appendix. Figure 6 As shown, in the weighing mechanism 3 provided in this embodiment, the driving component B includes a fixed plate 34 for supporting the weighing component 30 and a cylinder A35 connected to the fixed plate 34 and capable of driving the fixed plate 34 to move up and down.

[0060] Understandably, based on production requirements, the cylinder A35 is preferably a guide rod cylinder, but is not limited to this type of cylinder. The weighing mechanism 3 is also equipped with a base 36 for supporting and fixing the cylinder A35, and a shock-absorbing seat 37 can also be provided between the cylinder A35 and the fixing plate 34 to ensure the stability of the medicine receiving container 31 during its up-and-down movement and to ensure the measurement accuracy of the weighing component 30.

[0061] In addition, please continue to refer to the appendix. Figure 8As shown, in the blanking mechanism 4 provided in this embodiment, further preferably, the blanking mechanism 4 is also provided with a horizontally placed base plate 41, which is divided into a plurality of receiving areas, and each receiving area is fixedly surrounded by a retaining wall 400, and each receiving area and the retaining wall 400 surrounding it together form the receiving groove.

[0062] The driving member C includes a cylinder B42 connected to the base plate 41 and capable of driving the base plate 41 to rotate horizontally, thereby enabling the plurality of material taking portions 40 to move to the upper and lower container positions in sequence.

[0063] As can be understood, the cylinder B42 is a rotary cylinder. The base plate 41 can have an elongated plate structure (as shown in the accompanying drawings), at which time the receiving groove (i.e. the material taking portion 40) is configured as two and formed at both ends of the base plate 41 in the length direction; or the base plate 41 can have a circular plate structure, at which time the receiving groove (i.e. the material taking portion 40) can be configured as a plurality and arranged in a ring at the circumference of the base plate 41. In addition, the blanking mechanism 4 is also provided with a support 43 for supporting and installing the cylinder B42, the base plate 41, etc. Figure 8

[0064] Next, regarding the medicine dispensing mechanism 2.

[0065] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 5 As shown, in the medicine dispensing mechanism 2 provided in this embodiment, the flow channel 20 includes a first flow channel 201 and a second flow channel 202 connected to the discharge port of the first flow channel 201, the width of the first flow channel 201 is greater than the width of the second flow channel 202, and the downward projection of the discharge port of the funnel 10 falls completely into the first flow channel 201, and the downward projection of the discharge port of the second flow channel 202 falls completely into the medicine receiving container 31 placed on the weighing member 30.

[0066] The driving member A includes two vibrators 21 to provide vibration force to the first flow channel 201 and the second flow channel 202 respectively. Further preferably, the vibrator 21 is an adjustable vibrator with adjustable amplitude and frequency.

[0067] ​Description: In order to ensure that the drug particles discharged from the outlet of the flow channel 20 will not leak out when the receiving container 31 is replaced, the width of the flow channel 20, the vibration mode and the like are particularly controlled, specifically: ① the flow channel 20 is divided into a first flow channel 201 at the head end and a second flow channel 202 at the tail end, and the width of the first flow channel 201 is much larger than the width of the second flow channel 202, so as to realize accurate drug distribution; particularly preferably, the width of the second flow channel 202 can also be designed to be slightly larger than a single drug particle, so as to ensure that the drug particles are in a single, single walking state when walking in the second flow channel 202. ② At the beginning of work, the two vibrators 21 vibrate together, but when the weight of the drug particles falling into the receiving container 31 approaches the specified amount, the vibrator 21 driving the first flow channel 201 to vibrate stops working, and the vibrator 21 driving the second flow channel 202 to vibrate continues to work, but its vibration amplitude and / or frequency can be optionally reduced, thereby reducing the conveying speed of the second flow channel 202, ensuring that there is a long time gap between the drug particles discharged from the outlet of the second flow channel 202, thereby providing sufficient time for replacing the receiving container 31.

[0068] Next, regarding the medicine feeding mechanism 1.

[0069] Please refer to the accompanying Figure 2 to the accompanying Figure 4 , in the medicine feeding mechanism 1 provided in the embodiment, the sealing member 11 adopts the structure that: the medicine feeding mechanism 1 is also provided with an outer frame 12 for supporting and fixing the hopper 10; the sealing member 11 includes a sealing plate 110 located below the discharge port of the hopper 10 and slidingly arranged in the outer frame 12, and a handle 111 provided on the sealing plate 110 and held by an operator, when an external force is applied to the handle 111, the sealing plate 110 can be driven to open or close the discharge port of the hopper 10.

[0070] It can be understood that the sealing plate 110 is slidingly arranged in the outer frame 12, which can be realized by setting a sliding groove on the outer frame 12. This is a common knowledge, so it is not described in detail here.

[0071] Further preferably, please continue to refer to the accompanying Figure 3 and the accompanying Figure 4 , the medicine feeding mechanism 1 is also provided with a protective member 13, which is a hollow column structure with both upper and lower ends open, the protective member 13 is elastically and coaxially sleeved outside the discharge port of the hopper 10, and when the sealing plate 110 closes the discharge port of the hopper 10, the lower end of the protective member 13 is elastically tightly attached to the sealing plate 110, so as to prevent drug leakage.

[0072] Understandably, the protective component 13 is elastically connected to the outside of the discharge port of the funnel 10 by a combination of spring 14 and pin 15. Furthermore, depending on design requirements, the discharge port of the funnel 10 can extend into the upper end of the protective component 13 or protrude from the upper end of the protective component 13 (see Appendix). Figure 3 As shown), when the discharge port of the funnel 10 is exposed outside the upper end of the protective member 13, the gap between the discharge port of the funnel 10 and the upper end of the protective member 13 needs to be optimized so that the gap between the discharge port of the funnel 10 and the upper end of the protective member 13 is smaller than the particle size of the medicine, so as to ensure that no medicine leakage occurs.

[0073] In addition, an RFID tag can be installed on the outer frame 12 to facilitate automatic reading of the information of the drug delivery mechanism 1 during use. It can be understood that in this embodiment, the drug delivery mechanism 1 is designed as a modular structure, allowing for overall disassembly, assembly, and management.

[0074] Next, regarding other institutions.

[0075] If the position of the receiving container 31 near the discharge port of the flow channel 20 is defined as the receiving position, the drug weighing and dispensing equipment provided in this embodiment also includes a dehumidification mechanism. This dehumidification mechanism includes a gas supply device (such as an air dryer, air pump, or air tank) for supplying drying gas and an air nozzle 5 connected to the gas supply device via an air pipe. The air nozzle 5 is positioned at the receiving position to dry the drug particles in the receiving container 31, further improving weighing accuracy and ensuring that the quality of the drug particles is not affected. For details, please refer to the appendix. Figure 1 and attached Figure 2 As shown.

[0076] In addition, the weighing and dispensing equipment is equipped with protective devices such as a machine cover 60, a temperature and humidity recorder 61, and a dew point meter 62 to improve the safety and accuracy of the equipment during operation.

[0077] Note: The prefixes "first", "second", etc. (e.g., first flow channel, second flow channel, etc.) in the component names in this specification, as well as the suffixes "A", "B", "C", etc. (e.g., drive component A, drive component B, drive component C, etc.) in the component names, are only for ease of description and are not intended to limit the scope of implementation of this invention.

[0078] In summary, the drug weighing and dispensing equipment of the present invention has a simple and reasonable structure, and a high degree of integration and automation. It not only greatly improves processing efficiency and reduces labor intensity and labor costs, but also enables precise control of the weight of drug particles, ensuring the quality of weighing and dispensing operations.

[0079] In the foregoing description, numerous specific details are set forth to provide a thorough understanding of the present application. However, there can be cases in which certain implementations of the present application are practicable even though some of the specific details are not disclosed.
