Laser marker for the pharmaceutical industry PLANET DLPI-T

for tabletshigh-speedautomatic

Overview
One system for dual-side laser marking and precision inspection of pharmaceutical tablets. PLANET DLPI-T applies UV laser-etched IDs on both faces and inspects each tablet immediately after marking, enabling integrated traceability and simultaneous print & inspect processing.

Advantages

• Dual-side laser marking: UV laser marking on both tablet faces to enable identification on front and back.
• Print & Inspect in one step: simultaneous UV laser marking and inspection to reduce process time and handling.
• Zero blind spot inspection: complete surface coverage to ensure no uninspected areas.

Inspection & Imaging

• Multi-camera system: 10 × 2D cameras plus 2 × 3D cameras for comprehensive imaging and geometry capture.
• Real-time precision inspection immediately after marking to verify print quality, code readability and positional accuracy.

Defect Detection

• Detects defects such as cracks, incomplete or poor printing, color inconsistencies and other visual anomalies relevant to pharmaceutical quality control.

Feeding & Handling

• Precision feeding: integrated vibrating screw feeder for reliable separation and transfer of individual tablets.
• Guided stability: includes 25 pocket guides and 20 types of rotation guides to support and position a wide range of tablet shapes.
• Three-step safety/triple-checking system designed to prevent mixing and ensure accurate sorting.

User & Learning Features

• User-friendly interface with simplified recipe settings and accessible cleaning to support production uptime and operator tasks.
• Auto-study function: two-step automatic learning that records tablet features and positional data for repeatable handling and quick changeovers.

Video

• Embedded product video demonstrating system operation, marking results and inspection workflow.
