Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment, and in particular to a quantitative delivery device for 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 transport 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.

[0003] Existing technologies mostly utilize Automated Guided Vehicles (AGVs) for capsule transportation. AGVs are currently the most common applications, such as AGV handling robots or AGV carts. Their main function is focused on automated logistics handling. AGV handling robots automatically transport items to designated locations using special landmark navigation.

[0004] Because capsules need to be transported in fixed quantities during the production process, the capsule weight needs to be weighed multiple times when using automated guided vehicles to transport the capsules, which makes the process quite complicated. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a quantitative delivery device for capsules. The delivery core of this device rotates to cause the capsules in the main pipe to fall into the through groove. The bottom of the through groove is blocked by a baffle, which can fill the through groove with capsules. Since the volume of the through groove is limited, the number of capsules entering the through groove is quantitative. When the delivery core rotates, when the through groove containing the capsules rotates to the opening position of the baffle, the capsules are automatically discharged from the through groove.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a quantitative delivery device for capsules, comprising a base plate fixed to the ground by bolts or concrete, wherein a container for capsule dispensing and a first conveying structure connected to the container for quantitative capsule addition are installed on the base plate, the first conveying structure comprising a main pipe connected to the container, one end of the main pipe being connected to the container and the other end being connected to a conveying part, the conveying part comprising a conveying core, the conveying core being cylindrical, the end face of the conveying core having a plurality of through slots for capsule holding arranged in a circular array, and the bottom surface of the conveying core being in contact with a baffle.

The transport core is coaxially connected to the output shaft of the first motor, and a discharge pipe is connected to the end of the baffle away from the transport core.

[0008] Furthermore, the discharge pipe is connected to a secondary pipe, and a distributor is connected to the end of the secondary pipe away from the discharge pipe. The distributor includes a dispensing sleeve connected to the secondary pipe. The dispensing sleeve is fixedly installed on the base plate by a bracket. A movable plug is provided inside the dispensing sleeve. A second motor is fixedly installed at the end of the dispensing sleeve away from the bracket. The output end of the second motor is connected to the movable plug. At least two dispensing pipes are connected to the dispensing sleeve.

[0009] Furthermore, the container includes a box body, which is fixedly mounted on a base plate by a support rod. A feeding plate is provided inside the box body, which is mounted on the bottom surface of the box body by a first spring. A discharge port connected to the main pipeline is provided at the upper end of the box body.

[0010] Furthermore, it also includes a material cylinder for quantitative delivery of capsules, the material cylinder comprising a support structure mounted on a base plate, on which a cylinder body is mounted and a second conveying structure capable of sliding on the support structure to remove the cylinder body, the cylinder body being located below the dispensing pipe.

[0011] Furthermore, the supporting structure includes a supporting frame, which is mounted on a base plate via legs. The supporting frame is provided with an L-groove for mounting the cylinder. A placement block for supporting the cylinder is mounted in the L-groove via a second spring. The placement block is slidably mounted on the supporting frame via a guide rod. The second spring is fitted onto the guide rod. A sensor is provided at the end of the guide rod away from the placement block. A U-shaped frame that cooperates with the sensor is mounted on the supporting frame.

[0012] Furthermore, the supporting frame is provided with a slide for installing the second transport structure. The second transport structure includes a slider installed on the slide. The slider is fixedly installed on the transport plate. One end of the transport plate is provided with a telescopic plate for removing the cylinder. The telescopic plate is installed on the transport plate by a spring. The end of the telescopic plate extending outside the transport plate is provided with a chamfer. A limit plate is fixedly installed on the end of the transport plate away from the telescopic plate. The distance between the limit plate and the telescopic plate is not less than the diameter of the cylinder.

[0013] Furthermore, an extension plate is provided at the end of the conveying plate away from the limiting plate and the telescopic plate. The extension plate is installed at the output end of the linear drive device, and the linear drive device is fixedly installed on the base plate by a bracket.

[0014] Furthermore, the linear drive device is controlled by a sensor mounted on the guide rod.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] The device's transport core rotates to cause capsules in the main pipe to fall into the through-channel. The bottom of the through-channel is blocked by a baffle, which can fill the through-channel with capsules. Since the volume of the through-channel is limited, the number of capsules entering the through-channel is fixed. When the transport core rotates, when the through-channel containing capsules rotates to the baffle opening position, the capsules are automatically discharged from the through-channel.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0031] Example 1

[0032] Combination Figure 1 , Figures 3-6 As shown, the present invention provides a quantitative delivery device for capsules, including a base plate 1 fixed to the ground by bolts or concrete. A container 2 for capsule dispensing and a first conveying structure 3 connected to the container 2 for quantitative capsule addition are mounted on the base plate 1. The first conveying structure 3 includes a main pipe 31 connected to the container 2, with one end of the main pipe 31 connected to the container 2 and the other end connected to a conveying section 32. The conveying section 32 includes a conveying core 323, which is cylindrical. The circumferential array has multiple channels for holding capsules. The bottom surface of the transport core 323 is in contact with the baffle 324. The transport core 323 can rotate freely. By rotating, the transport core 323 causes the capsules in the main pipe 31 to fall into the channels. The bottom of the channels is blocked by the baffle 324, which can fill the channels with capsules. Since the volume of the channels is limited, the number of capsules entering the channels is fixed. When the transport core 323 rotates, when the channel containing the capsules rotates to the opening position of the baffle 324, the capsules are automatically discharged from the channels.

[0033] A cover plate 321 is provided above the transport core 323. The cover plate 321 is fixedly installed on the main pipe 31. The cover plate 321 has an opening that connects the main pipe 31 and the transport core 323. A first motor 322 is fixedly installed on the cover plate 321 by a bracket. The transport core 323 is coaxially connected to the output shaft of the first motor 322. The first motor 322 can provide power for the rotation of the transport core 323. The end of the baffle 324 away from the transport core 323 is connected to the discharge pipe 325. The baffle 324 connects the transport core and the discharge pipe 325 through the opening.

[0034] Combination Figures 3-8 As shown, the discharge pipe 325 is connected to a secondary pipe 33. A distributor 34 is connected to the end of the secondary pipe 33 furthest from the discharge pipe 325. The distributor 34 includes a dispensing sleeve 342 connected to the secondary pipe 33. The dispensing sleeve 342 is fixedly mounted on the base plate 1 by a bracket 341. The dispensing sleeve 342 is generally an inclined cylindrical shape. A movable plug 344 is provided inside the dispensing sleeve 342. The movable plug 344 is fan-shaped, and its radius is equal to the inner diameter of the dispensing sleeve 342. The movable plug can rotate freely within the dispensing sleeve 342. The dispensing sleeve 342 is fixedly mounted with a second motor 343 at one end away from the bracket 341. The output end of the second motor 343 is connected to the movable plug 344. The second motor 343 provides power for the rotation of the movable plug 344. The dispensing sleeve 342 is connected to at least two dispensing pipes 345. The dispensing pipes 345 are connected to the inner cavity of the dispensing sleeve 342. During the rotation of the movable plug 344, different dispensing pipes 345 can be blocked respectively, thus realizing the function of discharging materials from different dispensing pipes 345.

[0035] Combination Figure 2 As shown, the container 2 includes a container body 22, which is fixedly mounted on the base plate 1 by a support rod 21. A feeding plate 23 is provided inside the container body 22. The feeding plate 23 can slide freely inside the container. The diameter of the feeding plate 23 is slightly smaller than the inner diameter of the container body 22. The feeding plate 23 is mounted on the bottom surface of the container body 22 by a first spring 24. The upper end of the container body 22 is provided with a discharge port 25 connected to the main pipe 31. The first spring 24 is used to balance the weight of the capsules. After a capsule is added to the container body 22, the weight of the capsule will press the feeding plate 23, thereby compressing the first spring 24. As the capsule is discharged from the discharge port, the total weight of the capsules in the container body 22 is reduced. As the total weight of the capsules decreases, the first spring 24 releases its elastic potential energy, so that the capsules can remain submerged in the discharge port 25.

[0036] Example 2

[0037] Combination Figure 1 , Figure 9As shown, it also includes a material cylinder 4 for quantitative delivery of capsules. The material cylinder 4 includes a support structure 41 mounted on a base plate 1. A cylinder 42 and a second conveying structure 43 that can slide on the support structure 41 to remove the cylinder 42 are mounted on the support structure 41. The cylinder 42 is located below the distributing pipe 345, and the number of cylinders 42 is the same as the number of distributing pipes 345.

[0038] Combination Figure 10 As shown, the supporting structure 41 includes a supporting frame 411, which is mounted on the base plate 1 via supports 418. The supporting frame 411 has an L-groove 412 for mounting the cylinder 42. One end of the L-groove 412 is used to mount the cylinder 42, and the other end is used for removing the cylinder 42. A placement block 416 for supporting the cylinder 22 is mounted in the L-groove 412 via a second spring 415. The placement block 416 is slidably mounted on the supporting frame 411 via a guide rod 414. The second spring 415 is fitted onto the guide rod 414. A sensor is located at the end of the guide rod 414 away from the placement block 416. A U-shaped frame that cooperates with the sensor is mounted on the supporting frame 411. 416. The guide rod 414 prevents the second spring 415 from bending and deforming when it contracts under pressure. When the capsule is filled into the cylinder 22, the weight of the capsule applies pressure to the second spring 415. At this time, the placement block 413 drives the guide rod 414 to move downward. When the guide rod 414 moves to the point where the sensor contacts the U-shaped frame 416, it reaches the required load weight. At this time, the cylinder 42 is at the junction of the two ends of the L-groove 412, allowing the cylinder to slide out from the other port of the L-groove 412. The sensor will drive the second motor 343 to rotate through the external control module, causing the capsule to be discharged from the other dispensing pipe 345, thereby realizing the function of the other cylinder 42 for filling, and thus achieving the function of quantitative filling.

[0039] Combination Figure 11 and Figure 12As shown, the supporting frame 411 is provided with a slide rail 417 for mounting the second conveying structure 43. The second conveying structure 43 includes a slider 434 mounted on the slide rail 417. The slider 434 is fixedly mounted on the conveying plate 431. Since the moving plate 431 is mounted on the slide rail 417 via the slider 434, the conveying plate 431 can slide freely on the slide rail 434. One end of the conveying plate 431 is provided with a telescopic plate 432 for removing the cylinder 42. The telescopic plate 432 is mounted on the conveying plate 431 by a spring. The end of the telescopic plate 432 extending outside the conveying plate 431 is provided with a chamfer. When the conveying plate 431 is transported downwards towards the cylinder 42, the telescopic plate 432 contacts the bottom of the cylinder 42 through its inclined surface. Therefore, the spring can be compressed, causing the telescopic plate 432 to retract into the conveying plate 431. When the telescopic plate 432 moves beyond the cylinder 42, the spring releases its elastic potential energy, and the telescopic plate 432 extends out of the conveying plate 431. When the conveying plate moves in the opposite direction, the telescopic plate 432 contacts the side wall of the cylinder 42, pushing the cylinder 42 out. To prevent the cylinder 42 from tilting during movement due to the force of the telescopic plate 432, a limiting plate 433 is fixedly installed at the end of the conveying plate 431 away from the telescopic plate 432. The distance between the limiting plate 433 and the telescopic plate 432 is not less than the diameter of the cylinder 42. The limiting plate 433 supports the cylinder 42, preventing the cylinder 42 from tilting during movement due to the force of the telescopic plate 432.

[0040] An extension plate 435 is provided at the end of the conveying plate 431 away from the limiting plate 433 and the telescopic plate 432. The extension plate 435 is installed at the output end of the linear drive device 436. The linear drive device 436 is fixedly installed on the base plate 1 by a bracket. The linear drive device 436 is preferably a hydraulic device. The linear drive device 436 can realize the function of driving the conveying plate 431.

[0041] The linear drive device 436 is controlled by a sensor mounted on the guide rod 414. When the sensor contacts the U-shaped frame 416, it controls the linear drive device 436 to move via an external controller.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
