20% Cost Reduction + Higher Speed and Quality: Coolmay HMI PLC All‑in‑One Powers Labeling Machines

2026-01-20
Coolmay HMI PLC All‑in‑One is used in labeling machines, reducing costs by nearly 20%, increasing labeling speed, and improving product pass rates. It addresses key production challenges related to efficiency and cost.

Labeling Machine Functions and Applications

A labeling machine is industrial packaging equipment that automatically peels pre‑glued labels (arranged on a liner) using a peeling mechanism and applies them to containers or products. It supports flat surfaces, single‑ or multi‑side labeling, cylindrical labeling, partial or full‑wrap labeling, and application on recessed or corner areas.

Coolmay HMI PLC All‑in‑One Working Principle

The Coolmay HMI PLC All‑in‑One serves as the control core of the labeling machine. The labeling cycle follows these steps:

  1. A sensor sends a signal that the product is ready for labeling.
  2. The drive wheel rotates, keeping the label roll under tension.
  3. The liner changes direction, causing the label to separate.
  4. The product aligns with the label and the application is completed synchronously.
  5. A sensor sends a stop signal, the drive wheel halts, and the cycle ends.

Key Configuration and Technology

  1. Main Model and Hardware

    The model used is the EX3U‑8070H/HD, which supports 8‑axis pulse output and can drive up to 8 stepper motors. It features a 4.3‑inch HMI touch screen, offering high flexibility and easy operation.

  2. Component Coordination and Control

    • Proximity switch: Detects label position and sends signals to the all‑in‑one controller.

    • Stepper driver: Receives commands from the controller to manage positioning and speed.

    • Stepper motor: Drives the labeling motor and bottle‑rolling motor.


Performance Advantages

  1. Compliance with Core Standards

    The system meets requirements for counting accuracy, positioning precision, and labeling completeness.

  2. Competitive Advantages

    High‑speed pulse output ensures stable stepper motor control, resulting in faster labeling and lower defect rates. With its cost‑effective pricing, the solution reduces overall equipment costs by nearly 20%, achieving cost reduction, higher efficiency, and improved quality.
