Technical Field

The application relates to the field of automatic quality sampling detection, in particular to an automatic quality sampling reflux device in tablet production in the pharmaceutical industry.

Background

Many standard product production facilities have two product outlets, each outlet also having or being capable of having a product outlet and a sample detection port. Such mass production requires periodic sample withdrawal and timely testing to monitor and control product quality, otherwise, a large amount of waste or inferior medicine is generated. In principle, the weight or shape, integrity and metal content of each tablet should be strictly controlled during the production of the tablet product to avoid the difference in tablet weight or the exceeding of a specified limit value in terms of shape, appearance or metal content, but since the production of tablets is very large and each tablet is tested, the equipment investment cost is increased, so that currently, a small part of the product is periodically and randomly tested in continuous production in mass production.

For a double-outlet tablet press, a certain amount of products are extracted at each product outlet or the outlet of the corresponding subsequent processing equipment, the weight, the shape, the integrity or the metal content of the products are detected one by one, then the quality indexes of the products produced before and after the sampling time are evaluated according to the detection result, and whether the quality control device of the film press is adjusted or not is determined.

The rear part of the tablet press can be connected with a tablet screening machine or a gold detection machine or a visual detection device or a turnover material barrel or other conveying devices, and most of the extracted samples are at the outlet of the tablet press, so that the quality control precision of the tablet press can be fed back in time. The extraction location may also be after the sifter or gold sifter, as the tablets carry dust or are broken.

At present, tablet check out test set does not have the automatic device that flows back to turnover storage bucket or other conveyor of medicine, adopts the manual work to return back to turnover storage bucket to qualified products after the selective examination and needs a lot of human costs. And the qualified products are discarded, so that great cost waste is generated for the medicines with higher cost.

For tablets, in order to realize automatic backflow of products subjected to sampling inspection to a subsequent production device, only a spiral vibration hoisting machine or a vacuum material suction mode or a high-pressure air blowing mode is adopted. The spiral vibration lifting structure is complex, and the efficiency is low and the product is seriously abraded due to long spiral stroke; the vacuum material suction mode has a complex structure, is easy to damage products, is easy to pull out capsules which are not well locked, has large noise and consumes extremely electricity; the high-pressure air blowing can cause product collision damage, power consumption and large noise.

Therefore, the sampling inspection process in the production of the tablets urgently needs a convenient and simple device which does not damage products, consumes less power and has low noise and can ensure that qualified products after sampling inspection can effectively flow back to a turnover charging basket or other devices in time.
