Tablet-lacking detecting instrument for tablet counting machine

Abstract

The short tablet detecting instrument for tablet counting machine consists of one detecting head and one controller, and features the detecting head comprising sliding track, upper block, lower block and outer frame. The upper block is fixed on the lower block, the sliding track through the lower block is fixed onto the outer frame, and there are one lighting unit and one receiving unit installed on two ends of the upper block. The lighting unit emits parallel light beam to irradiate the medicine packing template of the tablet counting machine, and the receiving unit receives the reflected light, which is converted photoelectronically into electric signal fed to the controller for sending out bottle eliminating signal and tablet refilling signal based on the tablet shorting case. The present invention is suitable for detecting medicine sheets of different sizes, and the intelligent instrument has high detection rate, simple structure and low cost.

Description

technical field [0001] The invention relates to a detection instrument for lack of grains in a tablet counting machine, more specifically, an instrument for on-line detection of whether grains are lacking in a tablet counting machine in a production line when filling medicines. Background technique [0002] At present, the packaging form of solid preparation medicines is mainly bottle packaging. In the tablet bottle packaging production line, the function of the automatic tablet counting machine is to repeatedly extract a certain amount of medicine and fill it into the medicine bottle. It will determine the degree of consistency between the actual filling quantity and the required filling quantity in the filling process, that is, determine the Load measurement error rate. According to statistics, there are currently more than 15,000 pharmaceutical factories in China, and more than 100,000 drug packaging machines. Among them, a large number of tablet counting machines adopt ...

Problems solved by technology

The manual visual inspection method relies on human observation and capture ability. Long-term operation will make human eyes feel tired, and the detection accuracy and efficiency are very low; the weighing method uses a high-precision electronic weighing system to weigh the medicine poured into the bottle. Re-measurement, and then convert whether the filling volume of each bottle is accurate, its detection speed is slow and the accuracy is low; machine vision detection analyzes the collected images to detect whether it is missing grains, its detection accuracy is high, and at the same time It can also discriminate the defect and surface color difference of the tablet, but its software algorithm is complicated and the price is extremely expensive. Many small and medium-sized enterprises, especially small enterprises, cannot afford to buy it.
