LMS Overview

© 2020, SDS Systemtechnik, Calw, Germany LMS - Overview
• individual codes or numbers,
• data, graphics, barcodes
• easy to operate
• fast and reliable

 Machine concept:
• manual loading and circumferential positioning
• Motorized positioning of laser unit in two positions for adaption to
the wide range of diameters
• automatic marking with predefined tasks
• fast, 15 sec for a average “ECE-conform” data file
• interfacing to barcode systems and data bases
 Laser technique:
• sealed CO2 -Laser for operation without maintenance
• 30 Watt output power
• compact scanning module with adapted laser
• Modular concept for easy exchange and fast support

 Combined with a
pressure test system

 Machine concept:
• automated tire handling and positioning
(optional with TOF for two sided marking)
• Linear movement of laser unit (lift shift, optional with tilt)
• Rotating device for circumferential marking position
• Mechanical shutter with integrated air curtain and suction system
• Marking - and verification unit with “plug-in” setup for a
fast and easy exchange in case of failure
Automated Laser Marking System (LMS inline)
Attention:
The integrated primary suction system must be connected to an
external exhaust system.

 Machine concept: Single- or Two Position Process
Two Position Process
– first position for verification of sidewall information to define marking position
(optional with centering device)
– second position for tire marking.
With the two position process the laser unit is prepositioned while the tire is
loaded - faster cycle !
Single Position Process
– verification of sidewall information and laser marking in one position
(optional with external centering device)
The tire is rotating - laser and verification unit are moving only linear !

 Machine control:
• Rockwell Safety-PLC
• Servo drives
• For US an optional UL version is available
• PLC Software same concept as with ITT systems (G4 with tracking)
 Marking and Interfacing:
• Automatic marking with predefined tasks (teached)
• Setting dialog to prepare predefined marking tasks
• SQL/ODBC interfacing with process control system
• Inline with SDS conveyor system and standardized tire tracking
following Michelin Standard (same as with ITT systems)

 Laser technique:
• sealed CO2 -Laser for operation without maintenance
• 80 Watt output power (optional more to increase speed)
• compact scanning module with adapted laser
• Modular concept for easy exchange and fast support
 Verification technique:
• Proven system from established supplier (LMI, optional Keyence)
• With integrated illumination system
• Prepositioned camera system to “area of interest” with
tire contour measurement during loading
• Separate camera module for easy exchange and fast support
