Description

Technical Field

[0001] The present invention relates to the technical field of capsule detection, and in particular to a separation and conveying device for capsule detection. Background Art

[0002] Capsules are a common drug dosage form, which usually consists of an edible shell and the drug contained inside. After the capsule is produced, it needs to undergo multiple inspections on its conveyor line. Capsule inspection is an important link in ensuring the quality and safety of drugs, which covers the entire production process from raw materials to finished products.

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

[0004] The existing capsule weight detection method is mostly to weigh capsules one by one through a high-precision electronic scale. For capsules with low or high drug content, unqualified capsules are removed from the main conveyor line through pneumatic push rods, robotic arms or other automated equipment to complete the weight detection and sorting of capsules. This method is not completed by targeted equipment. Although this method can accurately detect unqualified capsules, for batch production of capsules, this working method of one-by-one detection is relatively slow. The high-precision electronic scale and the ejection equipment have a large workload, and the use and maintenance costs are high, which is not conducive to ensuring the rapid production of capsules.

[0034] During specific operation, the capsule enters the discharge groove 331 of the receiving roller 33 from the discharge port 1 32. The discharge groove 331 of the receiving roller 33 can store multiple capsules in a linear arrangement. After the receiving roller 33 rotates, the stored multiple capsules will be carried to the position of the discharge port 2 34. Under the action of gravity, the capsule will automatically fall. The airflow is input by the external fan, and the airflow is drained through the connecting cover 41 and the air expansion cover 42 to make the airflow blow horizontally to the falling capsule. The capsule generates horizontal acceleration and performs parabolic motion. Affected by its own mass, the parabola There are changes in the trajectory, which are intercepted by two sorting plates 447. Capsules with excessive weight will be intercepted by the front sorting plate 447 and fall onto the material receiving trough frame 1 444, while capsules with weight that meet the requirements will be intercepted by the rear sorting plate 447 and fall onto the material receiving trough frame 3 446, and capsules that do not meet the weight requirements will fall into the material receiving trough frame 2 445. The capsules are sorted and discharged to the outside of the box 5 through the inclined distribution of the material receiving trough frame 1 444, the material receiving trough frame 2 445 and the material receiving trough frame 3 446, thereby achieving the effect of quality inspection and screening of the capsules.

[0036] During specific operation, air is discharged through the air outlet 55 to ensure the air pressure balance inside the box 5 , and a screen 551 is provided to prevent foreign matter from entering the closed shell 54 through the air outlet 55 .

[0037] See also Figure 6 A plurality of guide plates 43 are fixedly connected in the air diffuser hood 42. The front end spacing of the plurality of guide plates 43 is the same, the rear end spacing is connected, and the front end spacing is smaller than the rear end spacing.

[0038] During specific operation, the airflow is guided by a plurality of guide plates 43 and ejected linearly and evenly, thereby ensuring the balance of blowing air to a row of capsules arranged linearly and ensuring the effectiveness of detection.

[0039] See also Figure 2 , Figure 3 and Figure 4The pushing assembly 31 includes a guide rod 316 fixedly connected between the left and right side walls of the feed hopper 2 and a reciprocating screw rod 317 rotatably connected between the left and right side walls of the feed hopper 2. The reciprocating screw rod 317 is threadedly connected to a moving seat 315, and the moving seat 315 is also slidably connected to the guide rod 316. A stirring shaft 312 is arranged on the lower side of the moving seat 315, and a plurality of forks 3121 are fixedly connected to the stirring shaft 312. The forks 3121 and the stirring shaft 312 are both made of soft rubber. An up and down reciprocating component 311 for controlling the up and down reciprocating movement of the stirring shaft 312 is commonly arranged on the moving seat 315; the left end of the reciprocating screw rod 317 and the left side rotating pin of the material receiving roller 33 extend to the outside of the feed hopper 2 and are linked by a synchronous belt and a pulley structure. The rear end of the reciprocating screw rod 317 extends to the outside of the box body 5 and is fixedly connected to the output end of the motor 1. The motor 1 is fixed The push assembly 31 also includes a gear 313 fixedly connected to the upper side of the stirring shaft 312, the gear 313 is meshedly connected to the wide rack 314, and the wide rack 314 is fixedly connected between the left and right side walls of the feeding hopper 2; the upper and lower reciprocating parts 311 include a movable column 3112 that slides through a plurality of limiting convex strips 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, and a sliding rod 3115 is fixedly connected to the upper part of the side wall of the movable column 3112, and a guide plate 3113 is fixedly connected between the left and right side walls of the feeding hopper 2, and a wave groove 3114 that undulates up and down is opened on the guide plate 3113, 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 capsule diameter.

[0040] During specific operation, the reciprocating screw rod 317 and the receiving roller 33 are driven to rotate synchronously by the motor 1, and the rotation of the reciprocating screw rod 317 drives the movable seat 315 to reciprocate left and right along the guide rod 316, so that the stirring shaft 312 stirs the capsule left and right, and 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, and at the same time, the sliding rod 3115 moves left and right along the wave groove 3114, which will produce height fluctuations, thereby driving the movable column 3112 to reciprocate up and down, and the movable column 3112 drives the stirring shaft 312 to reciprocate up and down, so that the stirring shaft 312 moves downward and pushes the capsule, and at the same time, the stirring shaft 312 moves left and right. The composite motion of movement and rotation controls the fork 3121 to stir the capsules. On the one hand, the distribution state of the capsules is changed by rotation. On the other hand, the left-right movement ensures the comprehensive downward movement of the capsules in the feed hopper 2. The soft brush 321 provides soft support for the capsules. When there is no pressure, the capsules cannot enter the discharge trough 331. When the stirring shaft 312 moves downward, the pressure generated can push the capsules through the gaps in the soft brush 321 and enter the discharge trough 331. Only when the capsules completely pass through the gaps in the soft brush 321 will they fall off, thereby ensuring that the single drop amount of the capsules is moderate, and preventing the vertical capsules from entering the discharge trough 331, thereby ensuring the uniformity of the falling state of the capsules.

[0041] See also Figure 3 and Figure 5 The material receiving assembly 44 also includes a pin rod 443 hinged on the lower left side of the material receiving trough frame 1 444 and the material receiving trough frame 2 445, and a pin rod 448 hinged on the lower right side of the material receiving trough frame 3 446.

The lower right sides of the material receiving trough frame 1 444 and the material receiving trough frame 2 445 are both rollingly matched with a cam 449. The two cams 449 are jointly fixedly connected to the rotating shaft 2 4410. The lower left side of the material receiving trough frame 3 446 is rollingly matched with a cam 442. The cam 442 Fixedly connected to the rotating shaft 1 441, the rotating shaft 1 441 and the rotating shaft 2 4410 both rotate and pass through the two divided plates 447 and are rotatably connected between the front and rear walls of the closed shell 54, and the installation positions of the pin rod 1 443 and the material receiving trough frame 1 444 and the material receiving trough frame 2 445 as well as the installation positions of the pin rod 2 448 and the material receiving trough frame 3 446 are all installed with torsion springs; the front ends of the rotating shaft 1 441 and the rotating shaft 2 4410 both extend to the outside of the box body 5 and are linked by a synchronous belt and a pulley structure, the rear end of the rotating shaft 1 441 extends to the outside of the box body 5 and is fixedly connected to the output end of the motor 2 6, and the motor 2 6 is fixedly connected to the outside of the box body 5.

[0042] During specific operation, the motor 26 drives the rotating shaft 1 441 to rotate, and the rotating shaft 2 4410 is driven to rotate synchronously by the rotating shaft 1 441 through the synchronous belt and pulley structure, and the rotating shaft 1 441 and the rotating shaft 2 4410 control the cam 1 442 and the cam 2 449 to lift and control the connecting trough frame 1 444, the connecting trough frame 2 445 and the connecting trough frame 3 446. The rebound effect of the torsion spring keeps the cam 1 442 and the connecting trough frame 3 446, and the cam 2 449 and the connecting trough frame 1 444 and the connecting trough frame 2 445 in contact and cooperation. The connecting trough frame 1 444, the connecting trough frame 2 445 and the connecting trough frame 3 446 are reciprocated and lifted at a high frequency to generate vibration, thereby ensuring that the capsule can slide out quickly.

[0043] During use: S1: a large number of capsules are put into the feed hopper 2, and then the motor 1 and the motor 2 6 are started. 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 movable seat 315 to move back and forth along the guide rod 316, so that the stirring shaft 312 stirs the capsules left and right. 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. At the same time, the sliding rod 3115 moves left and right along the wave groove 3114, which will produce height fluctuations, thereby driving the movable column 3112 to move back and forth up and down, and the movable column 3112 drives the stirring shaft 312 to move back and forth up and down, so that the stirring shaft 312 moves downward and pushes the capsules.

[0044] S2: The capsule enters the discharge groove 331 of the receiving roller 33 from the discharge port 1 32. The discharge groove 331 of the receiving roller 33 can store multiple capsules arranged linearly. The receiving roller 33 rotates under the drive of the motor 1. The stored multiple capsules will be carried to the position of the discharge port 2 34. Under the action of gravity, the capsule will automatically fall. The airflow is input by the external fan. Through the drainage of the connecting cover 41 and the air expansion cover 42, the airflow is blown horizontally to the falling capsules. The capsules generate horizontal acceleration and perform parabolic motion. Due to the influence of quality, the parabolic trajectory changes and is intercepted by two sorting plates 447. For capsules with excessive weight, they will be intercepted by the front sorting plate 447 and fall onto the material receiving trough frame 1 444, while capsules with weight that meet the requirements will be intercepted by the rear sorting plate 447 and fall onto the material receiving trough frame 3 446, and capsules that do not meet the weight requirements will fall into the material receiving trough frame 2 445. The capsules will be discharged to the outside of the box 5 through the inclined material receiving trough frame 1 444, the material receiving trough frame 2 445 and the material receiving trough frame 3 446.

The rebound effect of the torsion spring keeps the cam 1 442 and the connecting trough frame 3 446, and the cam 2 449 and the connecting trough frame 1 444 and the connecting trough frame 2 445 in contact and cooperation. The connecting trough frame 1 444, the connecting trough frame 2 445 and the connecting trough frame 3 446 are lifted up reciprocatingly at high frequency to generate vibration, so that the capsule slides out quickly.

[0046] S4: The capsules sliding out from the receiving chute rack 3 446 are weighed twice using a precision electronic scale to accurately screen out the capsules.
