Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically a device for continuous weighing and conveying of capsules. Background Technology

[0002] In the pharmaceutical industry, materials to be filled (such as liquid, powder, granular, or tablet drugs) are filled into gelatinous capsules using a filling machine. In capsule production, weighing and transporting equipment used in conjunction with the capsule machine is used to weigh a certain total weight of capsule shells or filled capsules and transport them to facilitate batch processing in the next step. With the development of technology, Automated Guided Vehicles (AGVs) have been widely used in intelligent manufacturing and have significantly improved production efficiency and saved production costs. The applicant has designed a device for continuous weighing and transporting of capsules, which, when used in conjunction with AGVs, will greatly improve capsule transportation efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a device for continuous weighing and conveying of capsules. The technical solution adopted by this invention is as follows:

[0004] A device for continuous weighing and conveying of capsules includes a Y-shaped distribution pipe connected to the capsule outlet, a distributor, a weighing module, a support bracket, a material hopper, and an AGV trolley. The Y-shaped distribution pipe includes a main feed section, a first branch, and a second branch. The distributor is mounted on the Y-shaped distribution pipe to allow the main feed section to connect to the first branch and the second branch, respectively. The first branch and the second branch lead to the first material hopper and the second material hopper, respectively. Weighing modules are mounted on the support bracket at positions corresponding to the first and second material hoppers. The weighing modules weigh the material hoppers and are signal-connected to the AGV trolley and the distributor. The AGV trolley transfers material hoppers that meet the weight requirements based on the weighing results of the weighing modules. Simultaneously, the distributor connects the first branch or the second branch based on the weighing results of the weighing modules to direct material to material hoppers that do not meet the weight requirements.

[0005] Preferably, the Y-shaped feed pipe is connected to the capsule outlet via a checkweigher. The checkweigher includes a good product feed pipe and a bad product feed pipe, and the good product feed pipe of the checkweigher is connected to the main feed section of the Y-shaped feed pipe.

[0006] A checkweigher, also known as an online checkweigher, weight detection machine, weight sorting machine, automatic checkweigher, or weight sorting machine, is a device that enables high-speed, high-precision weight detection and automatic sorting of products that are too light or too heavy in dynamic production line conditions. Checkweighers are existing technology and can be purchased and assembled, so their principles and structures will not be elaborated here.

[0007] Preferably, the feeder includes a drive mechanism and a feed disc, wherein the drive mechanism drives the feed disc to block the connection between the main feed section and the first branch or the second branch.

[0008] Preferably, the drive mechanism drives the dispensing disc to rotate within the main feeding section via a rotating shaft to respectively open the first branch and the second branch. The rotating shaft is located on the center line of the main feeding section, and the rotation radius of the dispensing disc is greater than the radius of the main feeding section, so that the rotation range of the dispensing disc within the main feeding section is less than 180 degrees. That is, the rotation angle of the dispensing disc relative to the center line of the main feeding section is an acute angle. When the dispensing disc blocks any channel, the end of the dispensing disc away from the rotating shaft will inevitably come into contact with the inner wall of the main feeding section. When the capsule flows down, it generates an impact force on the dispensing disc. The inner wall of the main feeding section provides support for the dispensing disc to resist this impact force, so as to ensure that the dispensing disc closes stably.

[0009] Preferably, the end of the dispensing disc away from the rotating shaft has two inclined surfaces, the included angle between the two inclined surfaces being equal to the maximum rotation angle of the dispensing disc within the main feeding section, so that the two inclined surfaces respectively cooperate with the inner walls on both sides of the main feeding section, and a flexible layer or elastic layer is provided on both inclined surfaces.

[0010] Preferably, the lifting bracket is provided with two support stations for supporting and positioning the first and second material buckets, and a weighing module for weighing the material buckets is installed on each support station; the lifting bracket suspends the material buckets for easy weighing, and because the material buckets are suspended, the loading platform of the AGV can drive under the material buckets for easy loading.

[0011] The beneficial effects of this utility model are as follows: The first and second material buckets in this device cooperate with the Y-shaped material distribution pipe and the AGV trolley. When the weight of the first material bucket reaches the standard, the AGV trolley transports it away. At the same time, the distributor controls the Y-shaped material distribution pipe to make the material flow to the second material bucket. During the filling process of the second material bucket, the AGV trolley brings the empty first material bucket. This cycle can realize uninterrupted weighing and transfer of materials. Moreover, the weighing module only needs to determine whether the weight of the material bucket reaches the standard. Based on the "yes" or "no" situation, it controls the start of the AGV trolley and the start of the distributor, realizing automated material transfer, improving production efficiency, and reducing production costs.

[0023] Example 1

[0024] like Figure 1-5As shown, a device for continuous weighing and conveying of capsules includes a Y-shaped feed pipe 2 connected to the capsule outlet of a capsule machine or other capsule production equipment, a feeder 3, a weighing module 4, a lifting bracket 5, a material bin 6, and an AGV trolley 7. The Y-shaped feed pipe 2 includes a main feed section 23, a first branch 21, and a second branch 22. The feeder 3 is disposed on the Y-shaped feed pipe 2 to allow the main feed section 23 to respectively connect to the first branch 21 and the second branch 22. The first branch 21 and the second branch 22 respectively lead to the first material bin 61. The second material bucket 62; the lifting bracket 5 is respectively provided with two support stations for supporting and positioning the first material bucket 61 and the second material bucket 62. Each support station is equipped with a weighing module 4 for weighing the material buckets. The weighing module 4 weighs the material buckets 6 and is connected to the AGV trolley 7 and the distributor 3 by signal. The AGV trolley 7 transfers the material buckets 6 that meet the weight standard according to the weighing result of the weighing module 4. At the same time, the distributor 3 conducts the first branch 21 or the second branch 22 according to the weighing result of the weighing module 4 to allow the material to pass to the material buckets 6 that do not meet the weight standard.

[0025] In this device, the first material bucket 61 and the second material bucket 62 cooperate with the Y-shaped distribution pipe 2 and the AGV trolley 7. The capsules flow from the main feeding section 23 to the first branch 21. When the weight of the first material bucket 61 reaches the target, the AGV trolley transports it away. At the same time, the distributor 3 controls the Y-shaped distribution pipe 2 to make the capsules in the main feeding section 23 flow to the second branch 22, and then to the second material bucket. During the filling process of the second material bucket 62, the AGV trolley brings an empty first material bucket to the discharge point of the first branch 21. This cycle can realize uninterrupted weighing and transfer of materials. The weighing module 4 only needs to determine whether the weight of the material bucket has reached the set value. Based on the "yes" or "no" situation, it controls the start of the AGV trolley and the distributor 3 to realize automated material transfer, improve production efficiency, and reduce production costs.

[0026] The Y-shaped feed pipe 2 is connected to the capsule outlet via the checkweigher 1. The checkweigher 1 includes a good product feed pipe and a bad product feed pipe. The good product feed pipe of the checkweigher 1 is connected to the main feed section 23 of the Y-shaped feed pipe 2.

[0027] The feeder 3 includes a drive mechanism and a feed disc 31. The drive mechanism drives the feed disc 31 to block the connection between the main feed section 33 and the first branch 21 or the second branch 22. The drive mechanism drives the feed disc 31 to rotate within the main feed section 23 via a rotating shaft 32 to connect the first branch 21 and the second branch 22 respectively.

[0028] Specifically, the rotating shaft 32 is located on the center line of the main feeding section 23, and the rotation radius of the distributing disc 31 is greater than the radius of the main feeding section 23, so that the rotation range of the distributing disc 31 within the main feeding section 23 is less than 180 degrees (in this embodiment, the rotation range of the distributing disc 31 is 90 degrees). That is, the rotation angle of the distributing disc relative to the center line of the main feeding section 23 on one side is an acute angle. When the distributing disc blocks any channel, the end of the distributing disc away from the rotating shaft 32 will inevitably come into contact with the inner wall of the main feeding section 23. When the capsule flows down, it generates an impact force on the distributing disc. The inner wall of the main feeding section 23 provides support for the distributing disc to resist this impact force, so as to ensure that the distributing disc closes stably.

[0029] Reference Figure 6 The end of the dispensing disc 31 away from the rotating shaft 32 has two inclined surfaces. The included angle between the two inclined surfaces is equal to the maximum rotation angle of the dispensing disc 31 in the main feeding section 23 (in this embodiment, the maximum rotation angle of the dispensing disc 31 is 90 degrees), so that the two inclined surfaces respectively cooperate with the inner walls of the two sides of the main feeding section 23, and a flexible layer or elastic layer 311 is provided on both inclined surfaces.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
