Description

Technical Field

[0001] The invention relates to a capsule weighing device which can be connected to a capsule filling machine for operation. Technical Background

[0002] At present, the fully automatic capsule filling machine used in the pharmaceutical industry includes a capsule sorting and separation mechanism, an empty capsule rejection mechanism, a filling mechanism and a powder adding mechanism, a capsule locking mechanism, a finished product discharging mechanism, a mold cleaning mechanism, a human-machine interface control mechanism, a mechanical transmission mechanism, a dividing turntable mechanism and a frame, a working platform, etc. The filled medicine can be powder, tablets or pills, etc. The finished capsules are generally weighed by manual sampling (5-10 capsules can be sampled at a time), which has low work efficiency and poor work stability. In addition, sampling can only be performed after a batch of products is completed, and real-time detection and weighing cannot be achieved online. If unqualified products are found in the sampling, all products in the batch will be judged as unqualified, resulting in a lot of waste. This not only increases the labor input cost, but also fails to guarantee the production efficiency and quality of the capsules. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and to provide an online capsule sampling, dropping, conveying and weighing device which can automatically sample, drop, convey and weigh capsules one by one.

[0005] The material suction side swing assembly includes a rocker arm, the upper end of which is connected to the side swing force source, and the lower end of which is equipped with a capsule suction head. The material cutting assembly is composed of a material cutting push rod and a material cutting power source. A feeding sheet is also installed under the capsule suction head, and a capsule discharge pipe is installed on the side of the electronic scale. The material discharge power source, the side swing force source, the material cutting power source and the electronic scale are respectively electrically connected to the microcomputer control circuit board and are uniformly controlled by it.

[0006] After adopting the present invention, the whole process of sampling and discharging, conveying, cutting, single-grain suction, weighing and discharging of finished capsules is completed in sequence through the work of the sampling and discharging plate and the discharging power source, the material cutting component and the material suction side swing component, realizing the online sampling and weighing process of finished capsules, and completely achieving real-time detection and weighing while producing. It ensures the advantages of stable, reliable, unattended and automatic optimization control of capsule weighing, saves a lot of human resources and maintenance time, and significantly improves the work efficiency and quality of capsule production.

[0008] Figure 2 for Figure 1 Right side view (after removing part of the box). DETAILED DESCRIPTION

[0009] Reference Figure 1 , Figure 2 It can be seen that the capsule online sampling, dropping, conveying and weighing device of the present invention used in conjunction with the capsule filling machine comprises a box body 1 (i.e., a frame), a capsule conveying pipe 2 arranged obliquely downward, a dropping hole 3 (corresponding to the specification of the capsule) is arranged on the capsule conveying pipe 2 and at the feeding position, a capsule slide 4 is arranged in the box body 1 and below the dropping hole 3 of the capsule conveying pipe 2, and a sampling discharge plate 5 (a discharge hole corresponding to the drop hole can also be arranged on it, when the discharge hole is at the same position as the drop hole) is arranged between the capsule slide 4 and the drop hole 3 of the capsule conveying pipe The finished capsules to be weighed are dropped when overlapping), the sampling discharge plate 5 is connected to the discharge power source 6 (a discharge cylinder); the capsule slide 4 is connected downward to the hollow tube 7 (which is connected and fixed to the fixing seat 21 and is made of acrylic material), and a material cutting assembly 9 is installed at the lower end of the hollow tube 7 (through the capsule guide tube 8), and a suction side swing assembly 10 is installed in the box body 1 and at the side edge of the lower end of the hollow tube 7, and an electronic scale 11 (with a weighing platform 12, whose accuracy is 0.1 mg) is installed in the box body 1 and below the suction side swing assembly 10.

[0010] The material suction side swing assembly 10 includes a rocker arm 13, the upper end of which is connected to a side swing force source 14 (a 90-degree side swing cylinder), and the lower end of which is equipped with a capsule suction head 15 (its suction and discharge are controlled by a solenoid valve). The horizontal position of the rocker arm side swing is docked with the end of the capsule guide tube and the material cutting assembly, and its vertical position is docked with the weighing platform of the electronic scale. The material cutting assembly 9 is composed of a material cutting push rod 16 and a material cutting power source 17 (a material cutting cylinder). A feeding sheet 18 is also installed under the capsule suction head 15, and a capsule discharge pipe 19 is installed on the side of the electronic scale 11. The material discharge power source 6, the side swing force source 14, the material cutting power source 17 and the electronic scale 11 are respectively electrically connected to the microcomputer control circuit board 20, and are uniformly regulated by it.

[0011] The working principle of the present invention is as follows: the capsule feeding pipe (and the box) is directly connected with the finished capsule discharge port of the capsule filling machine, and the finished capsules are sequentially discharged from the finished capsule discharge port into the capsule feeding pipe 2, that is, they are discharged while being produced. When online sampling is required, the discharge power source 6 drives the sampling discharge plate 5 to move, so that the finished capsules fall from the drop hole 3 of the capsule feeding pipe onto the capsule slide 4 (generally 5-10 capsules are dropped for one sampling), and pass through the hollow tube 7 to the capsule guide tube 8 at its lower end, and are cut and supported by the cutting push rod 16 of the cutting assembly 9. At this time, the side swing force source 14 of the suction side swing assembly 10 drives the rocking arm 13 to swing to the end of the capsule guide tube, and the material cutting power source 17 drives the material cutting push rod 16 to make only one capsule product fall each time and just be sucked by the capsule suction head 15 at the lower end of the rocking arm, and then drives the rocking arm to swing above the weighing table 12 of the electronic scale 11 (deflation of the capsule suction head) and gently put the capsule product on the weighing table for weighing. After weighing, the swing arm swings again to prepare to suck the next capsule product, and the feeding piece 18 under the capsule suction head naturally sends the weighed capsule product to the capsule discharge pipe 19 for discharge, thereby completing the whole process of sampling, feeding, cutting, single-grain suction, weighing, and discharging of the capsule product in sequence, realizing the online sampling and weighing process of the capsule product, and completely achieving real-time detection and weighing while producing (the qualified weight of the capsule product weighing is within a certain set range). The weight problem of the capsule product can be discovered and handled (cleaned) in time, and unnecessary drug waste can be eliminated (if the sampling and weighing is unqualified, it is determined that the capsule products produced in this batch are all unqualified, and the problem is discovered early and the batch is stopped for rectification). This high-precision, high-stability and efficient working mode can achieve a maximum accuracy of 0.5-1.0mg. The specifications of the drop hole of the capsule feeding pipe, the diameter of the capsule slide, the hollow tube, and the capsule catheter can be replaced according to the specifications of various types of capsules. The specific structural design is convenient for assembly and cleaning corresponding to different capsule specifications, which also shortens the maintenance time and improves work efficiency.
