Description

Technical Field

[0001] This utility model relates to the technical field of screening devices, and more specifically, to a capsule screening device. Background Technology

[0002] Capsules are a common drug dosage form, typically consisting of an outer shell and an inner powder. The outer shell is usually made of special film-forming materials such as gelatin or cellulose, which can protect the drug, mask unpleasant odors, and can also be designed to release the drug at specific sites as needed.

[0003] During production, problems can arise whether the medicine powder is filled manually or using automated capsule filling machines. For example, empty capsules (capsules without medicine powder) may be produced, or the amount of medicine powder filled may be insufficient. Both of these problems will affect the quality and efficacy of the medicine. To ensure the quality of the medicine, these substandard capsules need to be screened out.

[0004] Currently, air screening is one of the commonly used screening methods. Its principle is to use air force to blow away lightweight non-conforming products such as empty capsules. Although air screening is inexpensive and the equipment is simple, because capsules are prone to stacking, air screening cannot guarantee a high removal rate for empty capsules. Utility Model Content

[0005] The purpose of this invention is to provide a capsule screening device that can not only effectively screen out empty capsules, but also facilitate the subsequent repackaging of capsules.

[0006] This utility model is achieved through the following technical solution: The capsule screening device of this utility model includes a horizontally arranged tray, a plurality of grooves formed on the upper surface of the tray, a pair of rotating shafts horizontally arranged at both ends of the tray, a driving device for driving the rotating shafts to rotate, a bracket for supporting the rotating shafts, a negative pressure device communicating with the grooves, a feeding device arranged on one side of the tray, a storage box arranged on the side of the tray away from the feeding device, and a receiving device arranged directly below the tray; one groove is used to accommodate one capsule.

[0007] Furthermore, the bottom of the groove is an arc shape that matches the shape of the capsule.

[0008] Furthermore, the width of the upper end of the groove is greater than the diameter of the capsule.

[0009] Furthermore, a negative pressure hole is provided at the bottom of the groove, and the negative pressure hole is connected to the negative pressure device; the negative pressure hole penetrates the tray.

[0010] Furthermore, the negative pressure device includes a plurality of covers disposed on the lower surface of the tray, a negative pressure pipe connected to the cover, and a negative pressure machine connected to the negative pressure pipe; one cover is disposed over one of the negative pressure holes.

[0011] Furthermore, the driving device includes a horizontally arranged motor, the output shaft of which is connected to one of the rotating shafts; the motor is fixedly mounted on the bracket.

[0012] Furthermore, the feeding device includes a feeding box, a feeding hole opened on the side of the feeding box near the tray, and a gate valve provided at the feeding hole; the length of the feeding hole is equal to the length of the tray.

[0013] Furthermore, the receiving device includes a receiving box located directly below the pallet, a baffle inside the receiving box, a partition located below the baffle, a scraper located on the upper surface of the baffle, and a telescopic cylinder for driving the scraper to move along an axial direction perpendicular to the rotating shaft; the length direction of the baffle is parallel to the axial direction of the rotating shaft, the length direction of the baffle is parallel to the length direction of the scraper, and the length direction of the baffle is parallel to the length direction of the partition; the partition divides the receiving box into two independent parts; gaps are provided between both sides of the baffle and the inner wall of the receiving box.

[0014] Furthermore, the tray is connected to a vibration device, which includes a vibration motor connected to the tray.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the capsule screening device of this utility model simultaneously discharges a large number of capsules onto a tray via a feeding device, ensuring that each groove is filled with capsules as much as possible. Then, a drive device rotates the tray, causing capsules not yet in the grooves to flow into a storage bin. A negative pressure device is then activated to adsorb the capsules in the grooves. During this negative pressure adsorption process, the drive device slowly rotates the tray. When the grooves face downwards, capsules containing powder, due to their greater weight, experience less negative pressure than their weight, causing them to fall into the receiving device below for temporary storage. These capsules are considered qualified. The negative pressure device is then closed, and empty capsules, losing their suction, also fall into the storage bin below for temporary storage. These capsules are considered unqualified. Qualified and unqualified capsules are stored separately. This not only efficiently filters out empty capsules but also allows for quantitative dispensing of capsules because the number of grooves on the tray is constant, eliminating the need for a counting and dispensing step (which requires an operator).

Detailed Implementation

[0024] Example

[0025] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 5 As shown, the capsule screening device of this embodiment includes a horizontally arranged tray 11, a plurality of grooves 12 formed on the upper surface of the tray 11, a pair of horizontally arranged rotating shafts 13 at both ends of the tray 11, a drive device for driving the rotating shafts 13 to rotate, a bracket 15 for supporting the rotating shafts 13, a negative pressure device 20 communicating with the grooves 12, a feeding device 30 located on one side of the tray 11, a storage box 17 located on the side of the tray 11 away from the feeding device 30, and a receiving device 40 located directly below the tray 11; each groove 12 is used to accommodate one capsule. The bottom of the groove 12 is an arc shape adapted to the shape of the capsule. Specifically, in use, a large number of capsules are simultaneously discharged onto the tray 11 by the feeding device 30, so that each groove 12 is filled with capsules as much as possible (as shown in the attached diagram). Figure 1 - Appendix Figure 2(As shown in the attached diagram), then the drive device drives the tray 11 to rotate, causing the capsules that have not entered the groove 12 to flow into the storage box 17. Then, the negative pressure device 20 is turned on to perform negative pressure adsorption on the capsules in the groove 12. During the negative pressure adsorption process, the drive device drives the tray 11 to rotate slowly. When the groove 12 is facing downwards, the capsules containing powder in the groove 12 are heavier, so the negative pressure is less than the weight of the capsules, causing the capsules to fall into the receiving device 40 below for temporary storage (as shown in the attached diagram). Figure 3 - Appendix Figure 4 As shown in the diagram, these capsules are considered qualified. Then, the negative pressure device 20 is turned off, and the empty capsules lose suction and fall into the storage bin 17 below for temporary storage. These capsules are considered unqualified. Qualified and unqualified capsules are stored separately. This not only efficiently filters out empty capsules, but also, because the number of grooves 12 on the tray 11 is constant, allows for quantitative dispensing of the capsules, eliminating the need for a counting and dispensing step (which requires an operator to be present during dispensing).

[0026] In this embodiment, the width of the upper end of the groove 12 is greater than the diameter of the capsule.

[0027] In this embodiment, a negative pressure hole 16 is provided at the bottom of the groove 12, and the negative pressure hole 16 is connected to the negative pressure device 20; the negative pressure hole 16 penetrates the tray 11. The negative pressure device 20 includes multiple covers 21 disposed on the lower surface of the tray 11, negative pressure pipes 22 connected to the covers 21, and a negative pressure machine connected to the negative pressure pipes 22; one cover 21 covers one negative pressure hole 16. Specifically, this allows the capsule to fit better against the bottom of the groove 12, and the negative pressure generated by the negative pressure device 20 can more effectively act on the capsule through the negative pressure hole 16. The negative pressure in each groove 12 is independent and not interconnected. This avoids the situation where, when a qualified capsule falls from the groove 12, insufficient negative pressure suction causes the empty capsule to fall as well.

[0028] The driving device in this embodiment includes a horizontally arranged motor 14, the output shaft of which is connected to one of the rotating shafts 13; the motor 14 is fixedly mounted on the bracket 15. Specifically, the motor 14 drives the output shaft to rotate within a certain angle range, thereby driving the tray 11 to tilt.

[0029] The feeding device 30 in this embodiment includes a feeding box 31, a feeding hole 32 opened on the side of the feeding box 31 near the tray 11, and a gate valve 33 provided at the feeding hole 32; the length of the feeding hole 32 is equal to the length of the tray 11. Specifically, by opening the gate valve 33, the capsules in the feeding box 31 can be discharged onto the tray 11.

[0030] The receiving device 40 in this embodiment includes a receiving box 41 located directly below the tray 11, a baffle 42 located inside the receiving box 41, a partition located below the baffle 42, a scraper 43 located on the upper surface of the baffle 42, and a telescopic cylinder 44 for driving the scraper 43 to move along an axial direction perpendicular to the rotating shaft 13. The length direction of the baffle 42 is parallel to the axial direction of the rotating shaft 13, the length direction of the baffle 42 is parallel to the length direction of the scraper 43, and the length direction of the baffle 42 is parallel to the length direction of the partition. The partition divides the receiving box 41 into two independent parts. There are gaps between both sides of the baffle 42 and the inner wall of the receiving box 41. Specifically, the partition divides the receiving box 41 into two independent chambers, which are used to store qualified capsules and empty capsules, respectively. When the pallet 11 is not rotating to discharge material, the scraper 43 is located on one side of the upper surface of the baffle 42. After the pallet 11 begins to tilt and discharges qualified capsules onto the baffle 42, the telescopic cylinder 44 drives the scraper 43 to move to the other side of the baffle 42 and pushes the capsules on the baffle 42 into the receiving box 41. After the pallet 11 discharges empty capsules onto the baffle 42, the telescopic cylinder 44 pushes the scraper 43 to move and pushes the empty capsules into the receiving box 41 (separating them from the qualified capsules).

[0031] In this embodiment, the tray 11 is connected to a vibration device, which includes a vibration motor 14 connected to the tray 11.

[0032] In summary, the capsule screening device of this embodiment discharges a large number of capsules onto the tray 11 simultaneously via the feeding device 30, ensuring that each groove 12 is filled with capsules as much as possible. Then, the driving device drives the tray 11 to rotate, causing capsules that do not enter the groove 12 to flow into the storage box 17. The negative pressure device 20 is then turned on to perform negative pressure adsorption on the capsules in the groove 12. During the negative pressure adsorption process, the driving device drives the tray 11 to rotate slowly. When the groove 12 is facing downwards, the capsules containing powder in the groove 12 are heavier, so the negative pressure is less than the weight of the capsules, causing the capsules to fall into the receiving device 40 below for temporary storage. These capsules are qualified capsules. Then, the negative pressure device 20 is turned off, and the hollow capsules lose their suction and also fall into the storage box 17 below for temporary storage. These capsules are unqualified capsules. Qualified and unqualified capsules are stored separately. This not only efficiently filters out empty capsules from the capsules, but also allows for quantitative dispensing of capsules since the number of grooves 12 on the tray 11 is constant, eliminating the need for counting and dispensing.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
