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.

And, after manufacturing the 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.

The D/A module converts digital sensing information by a digital unit to analog.

The D/I module receives digital information by a digital sensor unit. For example, the D/I module receives a digital detection result of light around the ampoule vision inspection device.

The D/O module outputs each digital information to a corresponding control target. For example, when it is determined that the ampoule is defective, the D/O module outputs a drive stop control signal to the driving unit for transferring the conveyor, so that the transfer operation of the ampoule is stopped.

The IOT module communicates as IOT data with the manager terminal registered in advance for the quality inspection result including the OPC printing status of the ampoule, for example, the manager mobile phone.

In addition, if it is further explained in this regard, modules with various functions are required for the existing PLC system used in various environments, and accordingly, PLC manufacturers provide various modules that satisfy the requirements of users.

For example, a module having various functions, such as a digital input/output module, an analog input/output module, and a communication module, is used in a PLC system, and a system desired by a user is built through these various modules.

For example, the technology of Patent Document KR101778333 Y1 is an invention registered as such a technology, and specifically relates to a PLC system having a diagnostic module for diagnosing whether an output module of the PLC is defective in operation.

The above-described IOT module according to an embodiment uses these points to provide a PLC that provides an IOT function from the above-described IOT module, and through this, further optimized monitoring and control from the device side is made easy. .

For example, the PLC controller compares the size and foreign matter level of the ampoule checked through the above-mentioned area camera module with the preset standard ampoule size and foreign material level, and pre-previews the OPC printing state of the ampoule checked through the line camera module. It compares with the set standard OPC printing state, and determines whether the ampoule is good or bad according to the comparison result.

At this time, when the ampoule is defective as a result of the determination, the PLC controller determines that the ampoule is in an abnormal state and notifies a pre-registered manager terminal, for example, a manager mobile phone.

To this end, the PLC controller has an IOT module that communicates with the manager terminal as IOT data for the ampoule failure result, and communicates with the remote manager terminal about the ampoule failure result by the IOT module.

At this time, for example, the PLC controller outputs a drive stop control signal to the drive unit for transferring the conveyor, so that the transfer operation of the ampoule can be temporarily stopped when the ampoule is defective.

Therefore, through this, the ampoule vision inspection machine reduces the space occupied by the ampoule automated production line, secures the camera focal length, and improves the sharpness by blocking the light refraction phenomenon to perform accurate vision inspection.

In addition, during the vision inspection of the ampoule, the optimized object monitoring control is performed through the PLC controller according to an embodiment.

And, in this case, a diffuse reflection member is provided in the central portion of the total reflection mirror unit to block the light refraction phenomenon during the total reflection.

In addition, by reducing the camera focal length by the blocked and reflected light, the entire ampoule inspection section is narrowed and the line image of the ampoule to be inspected is taken, and thus the OPC of the ampoule is photographed as a whole.

And, a DSP unit that digitally processes the image of the ampoule by each camera module including the line image of the captured ampoule, and a PLC controller that inspects the quality including the OPC printing state of the ampoule by the processed image of the ampoule. include

Therefore, through this, the ampoule vision inspection machine reduces the space occupied by the ampoule automated production line, secures the camera focal length, and improves the sharpness by blocking the light refraction phenomenon to perform accurate vision inspection.

Port) selects the communication port (COM1, COM2, ... , COM10), the IP address is the IP address of the camera, and the trend of the history is Live Alternatively, it is possible to select a history to search for stored previous data, a history to select a date of a previous data search, and a period to select a search date period.

In Analog, Enable means whether the displayed data is used or not, String is the name of the data, Measure is the data unit, X-axis is the coordinates of the X-axis to display text on the screen, Y-axis displays the text on the screen The coordinates of the Y-axis to be used, Size is the size of the character, Color is the color of the character, Display Status is either Text or Trend, and the Minimum Range is the minimum value of data. , Range Max is the highest value of data, and Display Time is the time set for the time domain X coordinate among the trend coordinates when displaying a trend.

Enable of Digital Input indicates whether the displayed data is used or not, String is the name of the data, X-axis is the X-axis coordinate to display text on the screen, Y-axis is the Y-axis coordinate to display text on the screen , Size is the size of the text, Color is the color of the text, and Effect is the alarm method (fast blinking, slow blinking, screen blinking).

Set, Display Status is selected from Text or Trend, and DisplayTime is displayed as the set time of the time domain X-coordinate among Trend coordinates when displaying a trend.

Enable of Digital Output is whether the displayed data is used or not, String is the data name, X-axis is the X-axis coordinate to display text on the screen, Y-axis is the Y-axis coordinate to display text on the screen , Size is the size of the text, Color is the color of the text, Effect sets the alarm method (character fast blinking, slow blinking, screen blinking), and Control Status is It includes a function that allows administrators to arbitrarily set a program to select between ON/OFF control of the control system.
