Tamper Evident Corner Labeling Machine With PLC Smart Error Proofing Control

Servo-Driven Tamper-Evident Corner Labeler (≥70 CPM) — Engineered for Pharma, Agrochemical, and Cosmetics Packaging

Addressing the FDA's stringent "Tamper-Evident" compliance requirements for prescription drugs, OTC medications, and premium cosmetics in the North American market, the STB-FK provides a highly reliable end-of-line packaging solution.

It precisely applies tamper-evident seals over carton corners. Its stable output of ≥70 cartons/minute, combined with a rapid changeover design, perfectly matches the flexible, multi-SKU production models of US Contract Manufacturing Organizations (CMOs).

1. High-Speed Servo Closed-Loop Drive System 

• Value Extraction: The core dispensing and conveying mechanisms are powered by high-performance servo motors, forming a strict closed-loop control network. This technology guarantees that during continuous high-speed operations of ≥70 boxes/min, the motors experience zero step-loss and immediate response. This ensures an exceptionally low mechanical failure rate and long-lasting labeling precision.

2. PLC Smart Error-Proofing Control 

• Value Extraction: The entire machine is globally managed by an industrial-grade Programmable Logic Controller (PLC). Integrated with a highly sensitive photoelectric sensor network, the system strictly enforces a "no box, no label" operational logic. This fundamentally prevents material waste from blank dispensing and eliminates the risk of downtime caused by adhesive sticking to the conveyor belt.

3. Broad Media Adaptability & Quick Changeover Structure 

• Value Extraction: The label supply system features a high-capacity design compatible with industrial label rolls up to ø350mm in outer diameter and ø75mm inner core, significantly reducing the frequency of roll changes during production shifts. The labeling head accommodates label heights up to 120mm. Coupled with a quick-adjustment mechanical structure, a single machine can flexibly handle the single-sided or corner labeling needs of variously sized cartons, greatly enhancing the flexible manufacturing capability of the packaging line.
