Description

Automatic sampling inspection device

Technical Field

The utility model relates to the field of automatic quality detection, in particular to an automatic quality sampling device in capsule and tablet production.

Background

The quality of the product needs to be detected and controlled at any time in the production process of the standard product. In the pharmaceutical industry, in the process of producing products such as capsules, tablets and the like, the loading amount or weight or metal content or size and shape need to be strictly controlled, and the situation that the loading amount difference or tablet weight difference of the capsules or the metal content or the size and shape exceeds a specified limit value is avoided.

The sampling inspection is to extract a certain amount of products at the product outlet of production equipment such as a capsule filling machine or a tablet press or at the outlet of subsequent processing equipment according to requirements, detect the loading amount or weight or metal content or size and shape of the products one by one, evaluate the precision and quality of the products produced before and after the sampling time according to the detection result, and determine whether to adjust the quality control device of the equipment such as the capsule filling machine or the tablet press.

The capsule filling machine is connected with the capsule polishing machine in a butt joint mode, then connected with a material transferring barrel or other conveying devices, or connected with the gold detection machine in a butt joint mode, and then connected with the material transferring barrel or other conveying devices.

If the difference of the capsule filling amount is checked at regular time, the material is generally taken from the outlet of the capsule filling machine, so that the metering accuracy of the capsule filling machine can be fed back in time; however, since the capsule directly coming out of the capsule filling machine may contain a lot of powder, which is easy to cause weighing errors, and the powder may be retained on the weighing platform or block the channel to affect the subsequent detection precision, the capsule may be sampled and inspected after the polishing machine or the gold inspection machine.

For tablets, a tablet screening machine and a gold detection machine may be connected after the tablet press, and a sample may be extracted after the tablet press. The extraction location may also be after the sifter or gold sifter, as the tablets carry dust or may be broken.

For production monitoring of capsule contents or tablet weights, the regulatory requirements dictate that the particle weight of a poorly defined pharmaceutical product be compared with the average of a given quantity of the same batch withdrawn, since the quality indicators, such as the average contents or weights, of the capsule filling machine or tablet press machine may drift over time. Therefore, after sampling, the medicines are returned to the turnover material barrel or other conveying devices in time to be merged with the original same batch of products, or are thrown away. The existing capsule detection equipment does not have a device for automatically refluxing medicines to a turnover charging basket or other conveying devices, and a lot of labor cost is consumed when qualified products are manually refluxed to the turnover charging basket after sampling inspection. And the qualified products are discarded, so that great cost waste is generated for the medicines with higher cost.

In the general automatic detection process, the horizontal height of the capsule or the tablet is lower along with the movement, so that the product after sampling inspection automatically flows back to a subsequent production device, and at present, only a spiral vibration hoisting machine or a vacuum material suction mode or a plurality of high-pressure air blowing modes are 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, a device which is convenient and simple, does not damage products, has low power consumption and low noise and can lead qualified capsules or tablets after the spot inspection to flow back to a turnover charging basket or other conveying devices in time is urgently needed in the spot inspection procedure in the mass production of standard products.
