Description

Automatic ampoule packing machine {Apparatus for packing automatically ampoule}

The present disclosure relates to a technology for an automatic ampoule packaging machine, and relates to a technology for packaging and packaging an ampoule, which is a sealed container for liquid medicine.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

In general, an ampoule is a small colorless or colored transparent glass container containing a liquid substance, such as an injection solution for medical purposes or an oral drug. Since these ampoules seal the upper glass after filling the liquid, the filled liquid does not come into contact with materials other than glass, so it is hygienic and suitable for heat sterilization.

When the production of these ampoules is completed, a large number of ampoules can be packaged by repeatedly performing the operation of picking up a large amount of ampoules at a time and putting them down one line at a time from the ampoules automatic packaging machine.

In this case, the automatic ampoule packing machine has a path that moves to the same location each time when it is picked up and put down in this way, thereby creating a space between the ampoules. This is advantageous in terms of efficiency.

The prior art literature that is the background of the above technology is as follows.

(Patent Document 1) KR101660192 Y1

For reference, the technology of Patent Document 1 is the degree of technology capable of simultaneously holding a plurality of containers for substances, particularly vial bottles, for cosmetic, medical or pharmaceutical applications.

On the other hand, after additionally manufacturing such an ampoule container, quality control such as a close inspection and judgment process for the integrity of the ampoule container itself is very important.

In inspecting and confirming the presence or absence of such an ampoule, if the inspector visually confirms it, real-time inspection and full inspection are impossible, the inspection speed is slow, and the inspection result is dependent on the skill and fatigue of the inspector, so there is a problem of reduced reliability.

In addition, there is a disadvantage in that it is difficult to acquire quantitative image data for reflection in the production process and to calculate statistical data.

Therefore, by using a vision inspection device as an alternative to solve the above problems, competitiveness of ampoule quality can be secured through efficient quality management, reliability and inspection efficiency are improved by automating the inspection process, and defective image data of products are collected. Because a database can be built, effective quality control is possible.

In addition, using high-performance hardware and an algorithm to drive it, uniform inspection is possible without being affected by external factors such as fatigue and individual differences of the examiner, making it possible to inspect all ampoules quickly and accurately.

In general, a device for inspecting an ampoule using a vision inspection technique uses an imaging device to photograph the ampoule, and then performs a vision inspection of the ampoule by analyzing the color space distribution change of the image data acquired with the imaging device. Determine whether there is an abnormality.

Most of the conventional vision inspection apparatuses are configured in such a way that imaging equipment is installed only on one side of the ampoule to acquire image data for one side of the ampoule.

This configuration has a disadvantage that it is not easy to inspect the entire area of the ampoule. Therefore, to inspect the entire area of the ampoule, a rotation function for the ampoule and a plurality of inspection imaging equipment are provided, and real-time processing and analysis of the acquired image data is performed.

There is a need for a highly reliable ampoule vision inspection device and inspection method that is equipped with a possible image processing module and increases inspection efficiency by rapidly performing a series of inspection processes.

It is a highly reliable ampoule vision inspection technology.

In addition, a general vision inspection device is used in various manufacturing processes such as surface finish inspection of products, physical defect tracking, textile product inspection, color inspection, semiconductor manufacturing process inspection, and the like. The above technology is an ampoule vision inspection apparatus optimized for the purpose of inspecting the dimensional accuracy of the ampoule, the presence of foreign substances, and the printing state of the OPC (one point cut) ampoule.

However, in the ampoule vision inspection machine of the present applicant, the ampoule vision inspection machine occupies a certain space in a general automated ampoule production line to secure a camera focal length, etc., and it is advantageous for productivity and the like to occupy a narrow space as much as possible.

However, if the space is reduced, it is not easy to secure the focal length of the camera.

Therefore, through this, external input/output ports, that is, digital input, digital output, analog input (Analoge Input: 4-20mA input, etc.), RS-485 communication port, RS232 communication port, LAN (LAN) ) port, audio port, etc. are handled directly by the small UAV itself, so there is no need to discuss different specifications with each NVR company.

In addition, data output (D/O (data out)) for controlling external measuring devices, contact output, port for controlling alarm, etc., data input (D/I (data in)), analog input (Analog Input: 4-20mA input, etc.) is pre-processed by the MCU and delivered to the CPU, RS-485 communication port, LAN port, audio port, etc.

By trending data directly from Mera, administrators can easily grasp data such as water level, pressure, and temperature, and this has the effect of providing an efficient way to control external systems.

And, in this case, the ampoule vision inspector according to another embodiment converts the data input to the external input/output port into a database directly in the camera's own memory, and displays the data trend in graph format when displaying it as an image on the monitor. make it possible

To this end, in the ampoule vision inspection device according to another embodiment, analog or digital data such as fine dust processed with the collected image of the monitoring area or the monitoring area is stored as a database in the SD, so that the database together with the image is a character or graph It can be displayed on the screen of the central control center in the form of data trend.

The content displayed on the screen is a database of various conditions such as fine dust.

Suga is displayed together with the image, and when text is displayed on the image, the text of the text, the unit of the text value, the position of the text on the screen, font, color, etc. can be set.

And, at the time of warning, the expression text is displayed in one of the cases of flickering in a specified color, or text is still in a specified color and the entire screen flickers in a specified color or black and white.

In addition, when displaying the database for various situations in the image as a data trend in graph format, the text, unit, and color of the data can be displayed as set by the administrator.

Also, if the trend bar displayed on the image is moved at the desired time, the trend time value where the moved bar is located appears. After checking the data, the data value located on the moving bar automatically disappears. It includes a function to be displayed in either case of flickering in color or flickering in a specified color, text is still in a specified color, and the entire screen is flickering in a specified color in color or black and white.
