Empty capsule removing device for pharmaceutical production line

Abstract

The invention discloses an empty capsule removing device for a pharmaceutical production line. The device comprises three storage boxes from left to right; ordered conveying devices are arranged on the back sides of the storage boxes; a fixed rod is fixedly connected to the back side end surface of the storage box on the left side; the front side end surface of the fixed rod is fixedly connected with a screening box on the right side of the storage box on the left side; a screening cavity is formed in the screening box; an empty capsule discharge device is arranged on the screening cavity; thescreening cavity is provided with a discharge device positioned on the lower side of the empty capsule discharge device; the discharge device is used for discharging capsules not fully filled with medicaments; a capsule discharge device for discharging normal capsules is arranged on the lower side of the discharge device; and a locking device is arranged on the lower side end surface of the screening cavity. The empty capsule removing device for the pharmaceutical production line has the characteristics of higher capsule screening precision and lower screening error rate, and can screen the empty capsules, capsules with unqualified weights and the normal capsules.

Description

technical field [0001] The invention relates to the technical field of empty capsule removal, in particular to an empty capsule removal device for a pharmaceutical production line. Background technique [0002] During the production of capsule drugs, the drug powder is filled into the capsules through the filling machine, and during this process, the drug powder in the capsules may be spilled due to machine vibration or debugging errors, and empty capsules and capsules whose weight does not meet the standard are produced. It is necessary to discharge empty capsules and capsules whose weight does not meet the standard. Since the situation inside the capsules cannot be directly observed, they are currently screened by distinguishing weight. The current screening device mainly applies lateral force to the falling capsules through the airflow, making different Capsules of different weights have different parabolic trajectories, so that capsules of different weights are blown int...

AI Technical Summary

Problems solved by technology

[0003] Technical problem: The current screening device mainly screens the capsules by blowing air. Since the angle between the capsule and the airflow is not fixed when the capsule falls, the capsule screening process is not accurate enough, and there is a large screening error rate.
