Description

Technical Field

[0001] This invention relates to the field of capsule testing technology, and in particular to a sorting and conveying device for capsule testing. Background Technology

[0002] Capsules are a common drug dosage form, typically consisting of an edible outer shell and the drug contained inside. After production, capsules undergo extensive testing on their delivery line. Capsule testing is a crucial step in ensuring drug quality and safety, covering the entire production process from raw materials to finished product.

[0003] Among them, capsule weight detection is an important step to ensure drug quality and dosage accuracy. By accurately measuring the weight of each capsule, it can be ensured that the active ingredients of the drug are within the specified range, minimizing the difference in drug content in each capsule. Capsules that do not meet the weight requirements will be rejected by separating and conveying them separately.

[0004] Existing methods for capsule weight detection mostly involve weighing each capsule individually using high-precision electronic scales. For capsules with low or high drug content, non-conforming capsules are removed from the main conveyor line using pneumatic pushers, robotic arms, or other automated equipment. This completes the capsule weight detection and sorting. However, this method lacks specific equipment for this purpose. Although it can accurately detect non-conforming capsules, for mass production of capsules, this method of individual detection is relatively slow. The high-precision electronic scales and ejection equipment require a large workload and have high usage and maintenance costs, which is not conducive to ensuring rapid capsule production.

[0018] Beneficial effects:

[0019] 1. The arrangement mechanism used in this invention enables randomly distributed capsules to fall in a regular pattern, avoiding the problem of multiple capsules falling at once and colliding with each other when exposed to horizontal winds, which affects the accuracy of detection. This effectively ensures the validity of capsule weight detection. At the same time, the discharge trough can store a suitable amount of capsules at a time, and the overall arrangement is linear, thus ensuring that the amount of capsules detected at one time is sufficient and appropriate. This ensures both detection efficiency and detection accuracy.

[0020] 2. The sorting mechanism used in this invention can cause the capsules to generate parabolic motion by blowing air. Based on the relationship between weight and parabolic acceleration, under the same blowing conditions, the capsules are classified into three categories according to the principle that the smaller the mass, the farther it is thrown. The sorting is quick and saves time and effort.

[0021] 3. The arrangement and sorting mechanisms used in this invention work together to achieve batch weight detection of capsules, significantly improving the efficiency of capsule weight detection. Furthermore, it can automatically sort capsules according to their weight using the parabolic principle, ensuring that the drug dosage inside pre-inspected capsules fluctuates only within a small range. For pre-inspected capsules, a second weight verification can be performed using a precision electronic scale for accurate detection and screening. The pre-sorting method reduces the workload of subsequent precision weighing, making it quick, convenient, and cost-effective. Attached Figure Description

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] See Figure 1 , Figure 2 and Figure 3 A capsule detection sorting and conveying device includes a housing 5, which is divided into an outer shell 53 and a closed shell 54 from top to bottom. The outer shell 53 is cylindrical and the closed shell 54 is cuboid. The outer shell 53 and the closed shell 54 are internally connected. The upper end of the outer shell 53 has a discharge port 32 and the lower end of the outer shell 53 has a discharge port 34. A feed hopper 2 is integrally fixedly connected to the upper side of the outer shell 53 at the position corresponding to the discharge port 32. The feed hopper 2 and the outer shell 53 are jointly provided with an arrangement mechanism 3 for linearly arranging multiple capsules and conveying them into the closed shell 54. The front side and the bottom of the discharge port 34 are jointly provided with a sorting mechanism 4 for blowing and screening several capsules falling in rows.

[0032] See Figure 1 and Figure 3 The arrangement mechanism 3 includes a receiving roller 33 that is rotatably connected between the left and right side walls of the outer casing 53 by a pivot pin and fits into the inner wall of the outer casing 53. The receiving roller 33 has several discharge grooves 331 equidistantly opened on the side wall of the receiving roller 33. The feeding hopper 2 is provided with a pushing component 31 for pushing the capsule downward.

[0033] See Figure 1 , Figure 3 and Figure 5 The sorting mechanism 4 includes an air-expanding hood 42 fixedly extending through the front wall of the enclosed housing 54. A connecting cover 41 is integrally fixedly connected to the front side of the upper wall of the air-expanding hood 42. The connecting cover 41 and the air-expanding hood 42 are internally connected. The upper end of the connecting cover 41 is fixedly connected to the external fan outlet through a flange. A receiving assembly 44 for receiving falling capsules is provided inside the enclosed housing 54. The receiving assembly 44 includes two sorting plates 447 distributed below and behind the discharge port 34. The lower ends of the two sorting plates 447 are fixedly connected to the enclosed housing 54. At the bottom, a receiving trough frame 3 446 inclined to the lower right is provided between the two separate plates 447. On the side of the two separate plates 447 that are far apart from each other, a receiving trough frame 1 444 and a receiving trough frame 2 445 that are inclined to the lower left are respectively provided. The receiving trough frame 1 444 is located directly below the discharge port 2 34. A discharge port 1 51 is opened on the right side wall of the closed shell 54 at the lower position of the receiving trough frame 3 446. A discharge port 2 52 is opened on the left side wall of the closed shell 54 at the lower position of the receiving trough frame 1 444 and the receiving trough frame 2 445.

[0034] In operation, capsules enter the discharge trough 331 of the receiving roller 33 through the first discharge port 32. The discharge trough 331 of the receiving roller 33 can store multiple capsules in a linear arrangement. After the receiving roller 33 rotates, the stored capsules are carried to the second discharge port 34. Under the influence of gravity, the capsules fall automatically. An external fan inputs airflow, which is guided by the connecting cover 41 and the air diffuser 42, causing the airflow to blow horizontally onto the falling capsules. The capsules generate horizontal acceleration and undergo parabolic motion. Due to their own mass, the parabolic trajectory... The trajectory changes, and the capsules are intercepted by two separating plates 447. Capsules that exceed the weight limit will be intercepted by the front separating plate 447 and fall onto the receiving trough 444. Capsules that meet the weight requirements will be intercepted by the rear separating plate 447 and fall onto the receiving trough 446. Capsules that do not meet the weight limit will fall into the receiving trough 445. The capsules are sorted and discharged outside the box 5 by the inclined receiving troughs 444, 445, and 446, thus achieving the effect of quality detection and screening of the capsules.

[0035] See Figure 3 An air outlet 55 is provided on the rear side wall of the enclosed housing 54. The air outlet 55 corresponds to the position of the air diffuser 42. A screen 551 is fixedly installed on the air outlet 55.

[0036] In actual operation, airflow is discharged through the air outlet 55 to ensure the air pressure balance inside the housing 5, and a screen 551 is set to prevent foreign objects from entering the closed housing 54 from the air outlet 55.

[0037] See Figure 6 The air diffuser 42 is fixedly connected to a plurality of guide plates 43. The plurality of guide plates 43 have the same front end spacing and the same rear end spacing, with the front end spacing being smaller than the rear end spacing.

[0038] In actual operation, the airflow is guided by several guide vanes 43, and the airflow is sprayed out linearly and evenly to ensure the uniformity of blowing air onto a linearly arranged row of capsules and to ensure the effectiveness of the detection.

[0039] See Figure 2 , Figure 3 and Figure 4The pushing component 31 includes a guide rod 316 fixedly connected between the left and right side walls of the feed hopper 2 and a reciprocating screw 317 rotatably connected between the left and right side walls of the feed hopper 2. A movable seat 315 is threadedly connected to the reciprocating screw 317, and the movable seat 315 is also slidably connected to the guide rod 316. A stirring shaft 312 is provided on the lower side of the movable seat 315, and several support forks 3121 are fixedly connected to the stirring shaft 312. Both the support forks 3121 and the stirring shaft 312 are made of soft rubber. The movable seat 315 is provided with a reciprocating component 311 for controlling the up-and-down reciprocating movement of the stirring shaft 312. The left end of the reciprocating screw 317 and the left side pivot of the receiving roller 33 extend to the outside of the feed hopper 2 and are linked together by a synchronous belt and pulley structure. The rear end of the reciprocating screw 317 extends to the outside of the housing 5 and is fixedly connected to the output end of the motor 1. The feeding hopper 2 is fixedly connected to the outside of the feeding hopper 2; the pushing component 31 also includes a gear 313 fixedly connected to the upper side of the stirring shaft 312, the gear 313 meshing with the wide rack 314, the wide rack 314 fixedly connected between the left and right side walls of the feeding hopper 2; the reciprocating component 311 includes a movable column 3112 that slides through several limiting protrusions 3111 and is limitedly connected to the movable seat 315, the stirring shaft 312 is rotatably connected to the bottom of the movable column 3112, a sliding rod 3115 is fixedly connected to the upper part of the side wall of the movable column 3112, a guide plate 3113 is fixedly connected between the left and right side walls of the feeding hopper 2, the guide plate 3113 is provided with a wave groove 3114 that undulates up and down, and the sliding rod 3115 is slidably matched with the wave groove 3114; soft brushes 321 are fixedly connected to both sides of the discharge port 32, and the gap between the two soft brushes 321 is smaller than the diameter of the capsule.

[0040] In actual operation, the reciprocating screw 317 and the receiving roller 33 are driven to rotate synchronously by the motor 1. The rotation of the reciprocating screw 317 drives the moving seat 315 to move back and forth along the guide rod 316, causing the stirring shaft 312 to agitate the capsules in the left and right directions. At the same time, the stirring shaft 312 drives the gear 313 to move along the wide rack 314, causing the stirring shaft 312 to rotate. Simultaneously, the sliding rod 3115 moves left and right along the corrugated groove 3114, creating height fluctuations, which in turn drive the movable column 3112 to move up and down. The movable column 3112 drives the stirring shaft 312 to move up and down, thus causing the stirring shaft 312 to push the capsules downwards. The combined motion control fork 3121, which controls both movement and rotation, agitates the capsules. On one hand, rotation alters the capsule distribution, and on the other hand, left-right movement ensures the comprehensive downward movement of the capsules within the feed hopper 2. Soft brushes 321 provide soft support for the capsules. Without pressure, the capsules cannot enter the discharge trough 331. When the agitator shaft 312 moves downward, pressure is generated that pushes the capsules through the gaps in the soft brushes 321 into the discharge trough 331. Only when the capsules have completely passed through the gaps in the soft brushes 321 will they detach. This ensures that the amount of capsule falling at one time is moderate and also prevents capsules in a vertical position from entering the discharge trough 331, thus ensuring the uniformity of the capsule's falling state.

[0041] See Figure 3 and Figure 5 The receiving assembly 44 further includes a first pin 443 hinged to the lower left side of the receiving slot frame 444 and the receiving slot frame 445, and a second pin 448 hinged to the lower right side of the receiving slot frame 446. Both pins 443 and 448 are fixedly connected through the two dividing plates 447 and between the front and rear walls of the enclosed housing 54. The lower right side of the receiving slot frame 444 and the receiving slot frame 445 are both fitted with a second cam 449, which is fixedly connected to the second rotating shaft 4410. The lower left side of the receiving slot frame 446 is fitted with a first cam 442. Fixedly connected to the rotating shaft 441, both rotating shaft 441 and rotating shaft 4410 rotatably pass through the two dividing plates 447 and are rotatably connected between the front and rear walls of the closed housing 54. Torsion springs are installed at the installation positions of pin 443 and receiving trough frame 444 and receiving trough frame 445, and at the installation positions of pin 448 and receiving trough frame 446. The front ends of rotating shaft 441 and rotating shaft 4410 extend to the outside of the housing 5 and are linked together by a synchronous belt and pulley structure. The rear end of rotating shaft 441 extends to the outside of the housing 5 and is fixedly connected to the output end of motor 6. Motor 6 is fixedly connected to the outside of the housing 5.

[0042] In actual operation, motor 26 drives shaft 1 441 to rotate, which in turn drives shaft 2 4410 to rotate synchronously via a synchronous belt and pulley structure. Shaft 1 441 and shaft 2 4410 control cam 1 442 and cam 2 449 to lift the receiving slot frame 1 444, receiving slot frame 2 445, and receiving slot frame 3 446. The rebound action of the torsion spring keeps cam 1 442 in contact with receiving slot frame 3 446 and cam 2 449 with receiving slot frame 1 444 and receiving slot frame 2 445. The reciprocating high-frequency lifting of receiving slot frame 1 444, receiving slot frame 2 445, and receiving slot frame 3 446 generates vibration, ensuring that the capsule can slide out quickly.

[0043] In use: S1: Put a large number of capsules into the feed hopper 2, and then start motor 1 and motor 6. Motor 1 drives the reciprocating screw 317 and the receiving roller 33 to rotate synchronously. The rotation of the reciprocating screw 317 drives the moving seat 315 to move back and forth along the guide rod 316, so that the stirring shaft 312 stirs the capsules in the left and right direction. At the same time, the stirring shaft 312 drives the gear 313 to move along the wide rack 314, so that the stirring shaft 312 rotates. Meanwhile, the sliding rod 3115 moves left and right along the wave groove 3114, which will produce height fluctuations. This drives the movable column 3112 to move up and down. The movable column 3112 drives the stirring shaft 312 to move up and down, so that the stirring shaft 312 pushes the capsules down.

[0044] S2: The capsule enters the discharge trough 331 of the receiving roller 33 through the discharge port 32. The discharge trough 331 of the receiving roller 33 can store multiple capsules arranged linearly. The receiving roller 33 rotates under the drive of motor 1, and the stored multiple capsules are carried to the position of the discharge port 34. Under the action of gravity, the capsule will fall automatically. An external fan inputs airflow, which is guided by the connecting cover 41 and the air diffuser 42, so that the airflow blows horizontally towards the falling capsule. The capsule generates horizontal acceleration and performs parabolic motion. Due to the impact of quality, the parabolic trajectory changes. It is intercepted by two dividing plates 447. Capsules that exceed the weight limit will be intercepted by the front dividing plate 447 and fall onto the receiving tray 444. Capsules that meet the weight requirement will be intercepted by the rear dividing plate 447 and fall onto the receiving tray 446. Capsules that do not meet the weight limit will fall into the receiving tray 445. The capsules are sorted and discharged outside the box 5 by the inclined receiving trays 444, 445, and 446.

[0045] S3: Motor 26 drives shaft 1 441 to rotate. Shaft 1 441 drives shaft 2 4410 to rotate synchronously via a synchronous belt and pulley structure. Shaft 1 441 and shaft 2 4410 control cam 1 442 and cam 2 449 to lift the receiving slot frame 1 444, receiving slot frame 2 445 and receiving slot frame 3 446. The rebound action of the torsion spring keeps cam 1 442 in contact with receiving slot frame 3 446 and cam 2 449 with receiving slot frame 1 444 and receiving slot frame 2 445. The reciprocating high-frequency lifting of receiving slot frame 1 444, receiving slot frame 2 445 and receiving slot frame 3 446 generates vibration, causing the capsule to slide out quickly.

[0046] S4: The capsules sliding out from the receiving tray 3446 are subjected to secondary weight verification using a precision electronic scale in order to accurately screen out the capsules.
