Design and Implementation of Microcontroller-Based Digital Control Systems on Paper Cutting Machines in USUPRESS

Introduction

In the printing and publishing industry, paper cutting machines play a crucial role in producing high-quality products. The University of North Sumatra's printing and publishing unit, USUPRESS, utilizes a paper cutting machine with a semi-automatic control system to run the paper cutting process. However, this system has limitations, and the size of the paper cutting can only be adjusted manually using a press lever. This research aims to design and implement a digital control system that can drive paper guidelines according to the size entered by the operator, with one input for each set of size consisting of three sizes of paper cutting.

Background

The current semi-automatic control system used in USUPRESS has several limitations. The size of the paper cutting can only be adjusted manually, which can lead to inaccuracies and errors. This can result in a decrease in productivity and an increase in time and energy used by operators in cutting paper piles. Moreover, the current system does not provide any error compensation feature, which can lead to a significant impact on the accuracy of cutting.

Methodology

The engineering design process (EDP) was used in this study to design and implement the digital control system. The EDP involves several stages, including problem definition, research, design, prototyping, testing, and implementation. The system was designed to utilize a microcontroller to adjust the size of cutting as needed. The operator only needs to enter the desired size, and the system will automatically adjust the paper barrier.

System Design

The system consists of several components, including a microcontroller, a stepper motor, and a sensor. The microcontroller is programmed to adjust the size of cutting as needed, while the stepper motor is used to move the paper limiting forward or backwards. The sensor is used to detect the size of the paper cutting and provide feedback to the microcontroller.

Implementation

The system was implemented using the Arduino platform, which provides a user-friendly interface for programming and debugging. The system was tested and validated using several experiments, and the results showed that the system can move the paper limiting in one input and one set of size consisting of three sizes of paper cutting. However, there was still a size error, which was caused by the age of the old paper cutting machine and the presence of a slip on the stepper motor pulley.

Results and Discussion

The results of the experiments showed that the system can move the paper limiting in one input and one set of size consisting of three sizes of paper cutting. However, there was still a size error, which was caused by the age of the old paper cutting machine and the presence of a slip on the stepper motor pulley. Nevertheless, the error can be compensated using the Arduino program, which has a significant impact in reducing these size errors.

Conclusion

The implementation of microcontroller-based digital control systems on paper cutting machines in USUPRESS is an exemplary strategic step. The system provides several benefits, including increased productivity, reduced time and energy used by operators, and improved accuracy of cutting. However, further research can be done to overcome existing problems, such as finding solutions to the Stepper Motor Slip and renewing old engine components, in order to achieve better efficiency and accuracy.

Future Research Directions

Several future research directions can be explored to improve the system and overcome existing problems. These include:

Developing a more accurate and reliable sensor to detect the size of the paper cutting
Improving the design of the stepper motor to reduce the impact of slippage
Developing a more efficient and accurate algorithm to compensate for errors
Implementing a more user-friendly interface for the operator to enter the desired size

Additional Analysis and Explanation

The application of the digital control system to the paper cutting machine in the USUPRESS not only provides convenience for the operator, but also increases productivity in the paper cutting process. With this system, operators no longer need to regulate the size of cutting manually, thereby reducing the possibility of errors that can occur due to inaccuracies in measurements.

This digital control system works by utilizing a programmed microcontroller to adjust the size of cutting as needed. The operator only needs to enter the desired size, and the system will automatically adjust the paper barrier. In addition, with the error compensation feature applied, the user can calibrate to minimize the impact of the slippage on the motor and other factors that may affect the accuracy of cutting.

In terms of implementation, the results show that although there are still size errors, with the use of the right technology, these errors can be minimized. This is very important, considering the precision in slaughtering paper is very influential on the quality of the final product produced by Usupress. Thus, this research is not only beneficial for internal operations, but also has a positive impact on customer satisfaction.

Conclusion

In conclusion, the design and implementation of microcontroller-based digital control systems on paper cutting machines in USUPRESS is a significant step towards improving the productivity and accuracy of the paper cutting process. The system provides several benefits, including increased productivity, reduced time and energy used by operators, and improved accuracy of cutting. However, further research can be done to overcome existing problems, such as finding solutions to the Stepper Motor Slip and renewing old engine components, in order to achieve better efficiency and accuracy.
