With the rapid development of China’s economy and the improvement of people’s living standards, the packaging machine industry has ushered in good development opportunities. The application range of pillow-type packaging machines in the industry is also becoming broader. These devices inherit the advantages of traditional pillow-type packaging machines and expand many new functions based on their own characteristics and needs. This article will introduce the application of Hechuan Q1 motion control PLC and X3E EtherCAT bus servo in pillow-type packaging machines — the disposable cup bagging machine.

1. Introduction

Pillow-type packaging machines are widely used in the packaging industry of food, medicine, and other products. Most of the daily necessities and food packaging encountered in daily life are sealed by pillow-type packaging machines. With the rapid development of China’s economy and the improvement of people’s living standards, the packaging machine industry has ushered in good development opportunities. The application range of pillow-type packaging machines in the industry is also becoming broader. These devices inherit the advantages of traditional pillow-type packaging machines and expand many new functions based on their own characteristics and needs. This article will introduce the application of Hechuan Q1 motion control PLC and X3E EtherCAT bus servo in pillow-type packaging machines — the disposable cup bagging machine.

2. Hechuan Disposable Cup Bagging Machine Solution Introduction

2.1 Overall Control Model

The overall control adopts a virtual spindle with real axes at each station to ensure the synchronization requirements of each station and to realize the motion control of the crank-link mechanism for tracking cutting (Figure 1).

2.2 System Composition and Control Requirements

The disposable cup bagging machine mainly includes the following system components:

i. Counting System: The system needs to use high-speed pulse output to control the cup feeding belt and use high-speed counting functions to ensure the accuracy of high-speed cup counting.

ii. Cup Pushing System: Dynamically allocate incoming materials to enhance equipment operational efficiency in case of incoming material anomalies.

iii. Feeding System: Real-time calculation of the gear meshing position of the virtual spindle with the cup lifting axis and film releasing axis to adjust the relative position of the cup and film.

iv. Film Conveying System: Dual servo tension adjustment, color mark detection, and compensation. v. Sealing and Cutting System: Servo-controlled sealing knife platform completes tracking cutting control.

2.3 Control System Design

The control part of the system adopts the Hechuan Q1 motion controller, integrating Hechuan human-machine interface, servo, etc., to achieve the counting of cups, feeding, and accurate packaging of the equipment. The system control part is shown in Figure 2.

Figure 2 System Topology

Among them, the PLC is the core of the entire system, processing signal, data, and logical control. Its performance determines the quality of the entire system. The Q1 PLC model has 16 channels of high-speed counting and 8 channels of high-speed pulse output (frequency width of 200K), with powerful floating-point calculation capabilities and a rich peripheral instruction set.

The system uses Hechuan X3EB-EtherCAT servo, with a position loop scanning cycle of 250us. In synchronous position mode, it supports a minimum of 250us synchronous position cycle, which can well meet the synchronization control requirements of the equipment through the EtherCAT communication protocol.

3. Function Implementation

i. As shown in Figure 4, parameters such as packaging quantity, packaging rows, and film length can be set through the HMI. The program automatically calculates the automatic running speed of each station and the meshing position of the servo electronic gear, electronic cam, and virtual spindle, making product specification switching simple and convenient.

iii. High-speed cup counting, with a counting frequency of more than 1ms per cup.

iv. Film releasing servo 1 and film releasing servo 2 adjust film tension through HMI parameter settings.

4. Q1 Control Introduction

Figure 6 Q1 Motion Controller

i. Uses CODESYS automation software, supporting IL/LD/FBD/ST/SFC mixed programming.

ii. Various functions of motion control are realized through SoftMotion, integrating high-speed EtherCAT communication, motion control, IO input/output functions and supporting various bus communications (including Modbus TCP, CANopen, serial communication, etc.).

iii. The CPU unit comes with high-speed IO output, capable of controlling 8 pulse axes, with a maximum frequency of 200K.

iv. The CPU unit comes with high-speed IO input, capable of completing 16 channels of high-speed counting.

5. X3EB Servo Driver Introduction

The X3EB bus-type servo is the latest EtherCAT bus-type servo launched by Hechuan Technology, featuring rich functions and high cost-performance ratio, with a beautiful design and ease of use.

Performance features are as follows:

i. Supports EtherCAT communication.

ii. Position loop scanning cycle of 250us, supports a minimum synchronous position cycle of 250us in synchronous position mode.

iii. Synchronizes 100 axes within 1ms, under 300 nodes at a distance of 120m, with a synchronization error of 10ns and ±20ns synchronization jitter, ensuring system synchronization requirements.
