Description

Technical Field

[0001] This invention relates to the technical field of capsule filling, and more particularly to a capsule capping device and its method of use. Background Technology

[0002] In drug preservation and packaging, many medications are packaged in capsules. Medications packaged in capsules are generally powders or granules that irritate the esophagus and gastric mucosa, or have an unpleasant taste, are volatile, easily broken down by saliva in the mouth, or are easily inhaled into the trachea. Encapsulating these medications protects their efficacy and also protects the digestive and respiratory tracts. Removing the capsule shell may cause drug loss, waste, and reduced efficacy. A complete capsule consists of a cap, a body, and the medication inside. In the capsule manufacturing process, the cap and body are typically separated, the medication powder is injected into the body, and finally, a pressing mechanism is used to press the cap and body together.

[0003] In the prior art, after the capsule particles are capped, the capsule capping device usually tilts the tray at a certain angle to allow the capsule particles to detach from the tray. However, this method has a drawback: it cannot completely empty the capsule particles. For example, if the capsule particles get stuck in the placement hole of the tray, it is difficult for the capsule particles to detach, resulting in the problem of capsule particles remaining on the tray. Summary of the Invention

[0004] The first objective of this invention is to provide a capsule capping device that aims to solve the problem of capsule particle residue in existing capsule capping devices.

[0005] To solve the above technical problems, a capsule capping device is provided for preparing capsule shells into capsule granules. The capsule shell includes a first shell and a second shell. The first shell is placed on a first material tray, and the second shell is placed on a second material tray. The device includes a first driving assembly, a pressing component, a second driving assembly, a collection container, an air gun assembly, and a controller.

[0006] The second tray is detachably connected to the first drive assembly. The first tray is mounted on the second drive assembly. The first drive assembly and the collection container are respectively disposed on opposite sides of the second drive assembly. The first drive assembly is used to drive the pressing member and the second tray closer to or away from the first tray. The air gun assembly is connected to the first tray and is disposed below the first tray. The first drive assembly includes a telescopic member, a sliding member, and an elastic member. The pressing member is connected to the telescopic member. The telescopic member is provided with a sliding groove. The sliding member is slidably disposed in the sliding groove. The elastic member is disposed in the sliding groove and abuts against the telescopic member and the sliding member. The sliding member is used to connect to the second tray. The second drive assembly is used to drive the first tray to tilt.

[0007] The controller is electrically connected to the first drive component, the second drive component, and the air gun component, respectively.

[0008] Furthermore, the first driving component also includes a rotating component connected to the telescopic component, the rotating component being used to drive the telescopic component to rotate within a second preset angle range.

[0009] Furthermore, the range of the second preset included angle includes [0°, 180°].

[0010] Furthermore, the first material tray includes a plurality of spaced placement holes, a first vent hole, a second vent hole, and a third vent hole. The first vent hole, the second vent hole, and the third vent hole are all connected to the placement holes and the air gun assembly. The first material tray includes a first venting area, a second venting area, and a third venting area. The first vent hole is disposed in the first venting area, the second vent hole is disposed in the second venting area, and the third vent hole is disposed in the third venting area. In the direction from the first driving assembly toward the collection container, the first venting area, the second venting area, and the third venting area are arranged sequentially, and the diameters of the first vent hole, the second vent hole, and the third vent hole gradually decrease.

[0011] Furthermore, the second tray includes a tray body and a guide post, the guide post extending from one side of the tray body, and the diameter of the guide post gradually decreases in the direction away from the tray body; and,

[0012] A guide channel is formed on the first tray, and the diameter of the guide channel gradually decreases in the direction away from the main body of the tray.

[0013] Furthermore, the second drive assembly includes a rotary motor and a clamping member, the rotary motor being connected to the clamping member.

[0014] Furthermore, the air gun assembly includes an air pump, a third pipeline, and a venting component. The venting component is connected to the first material tray, and the air pump and the venting component are connected through the third pipeline.

[0015] Furthermore, the pressing element includes a pressing body and an extension post. The pressing body is connected to the first driving component, and the extension post is connected to the pressing body and disposed on the side close to the second driving component.

[0016] A second objective of this invention is to provide a method of using the above-mentioned capsule capping device, comprising the following steps:

[0017] S1: The first material tray is installed on the second drive assembly, and the second material tray is installed on the first drive assembly;

[0018] S2: The controller controls the first drive component to drive the pressing member and move the second material tray closer to the first material tray, so that the first shell and the second shell are combined into capsule particles;

[0019] S3: The controller controls the first drive component to drive the pressing element and move the second material tray away from the first material tray;

[0020] S4: The controller controls the second drive component to drive the first tray to move from the initial position to the preset position;

[0021] S5: The controller controls the air gun assembly to open, so that the capsule particles move into the collection container;

[0022] S6: The controller controls the air gun assembly to close and controls the second drive assembly to drive the first tray from the preset position to the initial position.

[0023] Furthermore, the first tray rotates from its initial position around the rotation center by a third preset angle before reaching the preset position.

[0024] Implementing the embodiments of the present invention will have the following beneficial effects:

[0025] In this embodiment, the capsule capping device is equipped with an air gun assembly that is connected to the first material tray. After the capsule capping device presses the first shell and the second shell together to form capsule particles, the first material tray is tilted and the air gun assembly is used to transfer the capsule particles to the collection container, ensuring that no capsule particles remain on the first material tray, thereby improving the production efficiency of capsule particles.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Please refer to Figures 1-6 This invention provides a capsule capping device 100 for preparing capsule shells into capsule granules. The capsule shell includes a first shell and a second shell. The first shell is placed on a first material tray 200, and the second shell is placed on a second material tray 300. The capsule capping device 100 includes a first driving assembly 110, a pressing member 120, a second driving assembly 130, a collection container 140, an air gun assembly 150, and a controller 160. The second material tray 300 is detachably connected to the first drive assembly 110. The first material tray 200 is mounted on the second drive assembly 130. The first drive assembly 110 and the collection container 140 are respectively located on opposite sides of the second drive assembly 130. The first drive assembly 110 is used to drive the pressing member 120 and the second material tray 300 to move closer to or away from the first material tray 200. The air gun assembly 150 is connected to the first material tray 200 and is located below the first material tray 200. The first drive assembly 110 includes a telescopic member 111, a sliding member 112, and an elastic member 113. The pressing member 120 is connected to the telescopic member 111. The telescopic member 111 is provided with a sliding groove 1111, and the sliding member 112 is slidably disposed in the sliding groove.

[0040] Within 1111, an elastic element 113 is disposed within the sliding groove 1111 and abuts against the telescopic element 111 and the sliding element 112. The sliding element 112 is used for connection to the second tray 300, and the second drive assembly 130 is used to drive the first tray 200 to tilt. The controller 160 is electrically connected to the first drive assembly 110, the second drive assembly 130, and the air gun assembly 150, respectively. Exemplarily, the elastic element 113 is a compression spring, used to cause the second tray 300 to move away from the first tray 200 and return to its original position when the pressing element 120 does not apply pressure to the second tray 300.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 In this embodiment, the capsule capping device 100 is equipped with an air gun assembly 150, which is connected to the first material tray 200. After the capsule capping device 100 presses the first shell and the second shell together to form capsule particles, the first material tray 200 is tilted and the air gun assembly 150 is used to transfer the capsule particles to the collection container 140, ensuring that no capsule particles remain on the first material tray 200, thereby improving the production efficiency of capsule particles.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the first drive assembly 110 further includes a rotating member 114, which is connected to the telescopic member 111 and is used to drive the telescopic member 111 to rotate within a second preset angle range.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the second preset angle ranges from [0° to 180°]. For example, in this embodiment, the second preset angle is 180°. After the pressing member 120 applies pressure to the first and second shells to close them and form a capsule, the rotating member 114 drives the pressing member 120 to rotate 180°, ensuring that the pressing member 120 does not affect the subsequent removal of the capsule. Of course, in specific applications, the second preset angle can also be 170°, 160°, 150°, 140°, 130°, 120°, 110°, 100°, 90°, 80°, 70°, 60°, 50°, 40°, 30°, 20°, or 10°.

[0044] Please refer to Figure 1 , Figure 3 , Figure 5In one possible implementation, the first tray 200 includes a plurality of spaced placement holes 210, a first vent hole 220, a second vent hole 230, and a third vent hole 240. The first vent hole 220, the second vent hole 230, and the third vent hole 240 are all connected to the placement hole 210 and the air gun assembly 150. The first tray 200 includes a first venting area 250, a second venting area 260, and a third venting area 270. The first vent hole 220 is located in the first venting area 250, the second venting area 230 is located in the second venting area 260, and the third venting area 240 is located in the third venting area 270. In the direction from the first drive assembly 110 toward the collection container 140, the first venting area 250, the second venting area 260, and the third venting area 270 are arranged sequentially, and the apertures of the first vent hole 220, the second venting hole 230, and the third venting hole 240 gradually decrease. For example, since the distance from the capsule particles to the collection container 140 is different at different locations, the force required to move the capsule to the collection container 140 is also different. It is understood that the aperture of the first vent 220 in the first venting zone 250, which is farther away from the collection container 140, is set to be larger, and the aperture of the third vent 240 in the third venting zone 270, which is closer to the collection container 140, is set to be smaller. The capsule filling machine of this application is equipped with an air gun assembly 150. After the capsule particles are prepared, the first material tray 200 is tilted by the third drive assembly, and then the air gun assembly 150 blows all the capsule particles into the collection container 140. In addition, with the first air hole 220, the second air hole 230 and the third air hole 240 with different aperture sizes, the third air hole 240 closer to the collection container 140 has a smaller aperture, and the first air hole 220 farther away from the collection container 140 has a larger aperture. This structural design can control the airflow so that all the capsule particles can fall into the first material tray 200 and no capsule particles will remain in the first material tray 200.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3In one possible implementation, the second tray 300 includes a tray body 310 and a guide post. The guide post extends from one side of the tray body 310, and its diameter gradually decreases in the direction away from the tray body 310. A guide channel is formed on the first tray 200, and its diameter gradually decreases in the direction away from the tray body 310. Exemplarily, the guide post has a circular cross-section and is frustum-shaped. The end of the guide post connected to the tray body 310 has a larger diameter, and the end away from the tray body 310 has a smaller diameter. Similarly, the guide channel has a circular cross-section and is frustum-shaped. The end of the guide channel closest to the tray body 310 has a larger diameter, and the end away from the tray body 310 has a smaller diameter. It should be noted that the guide post is located at the center of the second tray 300, and the guide channel is located at the center of the first tray 200. The arrangement of guide posts and guide channels facilitates the guide posts entering the guide channels. Understandably, the cooperation between the guide posts and guide channels helps improve the accuracy of the fit between the first material tray 200 and the second material tray 300, making the central axes of the first material tray 200 and the second material tray 300 coincide. This, in turn, helps the first shell and the second shell to align, thereby completing the pressing and improving the pressing accuracy.

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the second drive assembly 130 includes a rotary motor 131 and a clamping member 132, with the rotary motor 131 connected to the clamping member 132.

[0047] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the air gun assembly 150 includes an air pump (not shown), a third conduit 151, and a vent 152, the vent 152 being connected to the first material tray 200. The air pump and the vent 152 are connected via the third conduit 151. Exemplarily, the clamping member 132 is used to secure the first material tray 200 located at the capsule capping station.

[0048] Please refer to Figure 1 , Figure 2 , Figure 3 In one possible implementation, the pressing member 120 includes a pressing body 121 and an extension post 122. The pressing body 121 is connected to the first drive assembly 110, and the extension post 122 is connected to the pressing body 121 and disposed on a side close to the second drive assembly 130. Exemplarily, when the first shell and the second shell are closed, the telescopic member 111 drives the pressing member 120 to move, thereby causing the extension post 122 to apply pressure to the second shell, thus connecting the second shell to the first shell.

[0049] Please refer to Figure 1 , Figure 4 , Figure 7 The second objective of this invention is to provide a method of using the capsule capping device 100 described above, comprising the following steps:

[0050] S1: The first material tray 200 is installed on the second drive assembly 130, and the second material tray 300 is installed on the first drive assembly 110;

[0051] S2: The controller 160 controls the first drive assembly 110 to drive the pressing member 120 and move the second material tray 300 closer to the first material tray 200, so that the first shell and the second shell are combined into capsule particles;

[0052] S3: Controller 160 controls the first drive assembly 110 to drive the pressing element 120 and move the second material tray 300 away from the first material tray 200;

[0053] S4: Controller 160 controls the second drive assembly 130 to drive the first tray 200 from the initial position to the preset position; for example, Figure 1 The position of the first tray 200 shown is the initial position. Figure 4 The position of the first tray 200 shown is a preset position.

[0054] S5: Controller 160 controls the air gun assembly 150 to open, so that the capsule particles move into the collection container 140;

[0055] S6: Controller 160 controls the air gun assembly 150 to close and controls the second drive assembly 130 to drive the first material tray 200 from the preset position to the initial position.

[0056] In one possible implementation, the first tray 200 rotates from its initial position around the rotation center by a third preset angle before reaching a preset position.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
