GBD

Abbreviation for gap bulk density. It denotes the pressed density of substrate mat isolating the ceramic substrate from the metal shell of an automotive catalytic converter.

SPC (Statistical Process Control) measurement

It is a testing measurement to check e.g. measurement system capability. Usually a special SPC part with known values is used. Comparing the actual measurement values with the known features, it can be checked, if a measurement system has a proper operational system mode or if it has to be re-calibrated.

The known SPC part features are typically stored in the SPC measurement template.

InnoMeas CMS Systems

The InnoMeas CMS systems are designed with special respect to the inspection of automotive catalytic converters. Size and shape are measured before and after the canning process. Employing laser point triangulation preset sectional planes of the monolith and the canned converter can be measured.
 Additionally, with proper accessories installed, the mat weight can be determined and bar or DMC codes can be read. 
The gap bulk density (GBD) is evaluated as an important measure for quality control. With optional software reporting tools a surveillance of process parameters is possible. Not only round samples can be measured. Elliptic, sectional and even potato shaped are possible to be inspected

Basic Setup

The monolith or converter is put on a rotary table

(no centering required). The triangulation laser sensor is mounted on a vertical positioning stage (z-axis), which allows automatic approach to the preset sectional planes for the particular measurement.

z-axis including the sensor as well as all controllers and supplies for the entire measurement system are implemented in a dust proof shielded housing. The rotary table is accessible for loading the parts of investigation by robots or manually. The housed z-axis assembly and the rotary table are bolted to a bottom rail. Aligning the z-axis with respect to the rotary table, the measuring range of the laser sensor is coarsely adjusted.
All measuring features are software controlled and via communication ports prepared for automated operation.

Standard Model Layouts of InnoMeas CMS

InnoMeas CMS I-type

Integrated model, focused on widely automated applications.

It is reduced to its essential components, i.e. the measuring unit and the rotary axis actuator. Assembled on a mounting rail, their position can be easily changed with respect to customer requirements.

An IPC system including all controllers and supplies is mounted in the sealed off measuring unit.

InnoMeas CMS I-type is dedicated for the use in manufacturing facilities (e.g. “canning facilities”), where no permanent operator interaction is necessary. Acting as a component of a production line, the controlling is entirely put to a higher level operation control system. However, adding a monitor and other devices like keyboard, mouse and a screen the I-type version converts to a stand-alone manually controlled inspection system.

InnoMeas CMS C-type

Compact model, dedicated to semi-automated product lines.
InnoMeas C-type is laid out for manual control as well as for automatic control. Housed in small foot print rack on wheels, it contains the measuring unit, the IPC (mounted in the bottom case) and a touch screen.
The measuring unit comprises of the rotary table and the sealed off z-axis assembly both mounted to a bottom rail for alignment to each other. The z-axis assembly contains the vertical axis with the laser sensor and all electrical supplies and controllers.

Key feature is the system‘s versatility. Compact outlines combined with convenient access to all components. The rack wheels allow operation at different locations. Controlling can done by a simple push button assembly (e.g. worker‘s mode), by the touchscreen (e.g. expert‘s mode) or by interfacing to super ordinated computer system.

A variety of peripherals like barcode or DMC code reader, label printer, mat scale etc. can be implemented.

InnoMeas CMS P-Type

P-Type Systems are designed with special respect to applications in test labs like prototype inspection or analysis of production samples. The large system rack allows containing of a variety of peripheral accessory devices such as scales, micrometer gauges, printers or scanners. CMS P-Type systems include a full-fledged PC working desk.

InnoMeas CMS HS

A new development especially for robotic canning processes. The horizontal orientation of the z-axis and the rotary stage in combination with an automatic part clamping allow high throughput rates. The entire system concept is dedicated to be part of an automated robot process chain.
