About Erhardt+Leimer

ELCorruMatic

The board quality and productivity of many corrugators is still largely dependent on the performance of the operators. With the trend of order lengths reduction the operators are not able to produce constant, high quality corrugated board whilst, at the same time, achieving a high productivity level from the corrugator. The solution to this situation is the automation of the corrugated board production process. With the ELCorruMatic, Erhardt+Leimer Corrugated offers an automation network, which can be adapted to the specific requirements of the respective corrugated board production by its modular product design.

Consequently an extension of the ELCorruMatic system is possible according to the increasing market demands. The product range includes modules for the automatic synchronization of the wet end and dry end section (product group CSM) and for the automatic control of all quality-related parameters product group TCCM). The upgrade from the basic module to the high-end version can be done step by step – the extension to more functionality is possible at any time. Both systems are working separately and can be combined with one another. The systems run via a common hardware-level for the respective modules. Aside these innovative systems the company has developed the WarpMeter, a board flatness measuring beam, to check the flatness of the current order. All machine settings are automatically adjusted according to pre-setted values.

Function

The ELCORRUMATIC CCM (Corrugator Control Module) includes all corrugated cardboard plant settings related to the quality parameters for the manufacture of corrugated cardboard. This module automatically controls, with reference to the paper and corrugation profiles used in the order, all process parameters related to the temperature, the application of adhesive, the web tension, the steam pressures and optionally the roller pressures. Here variables superimposed on the control characteristics such as speed changes or wrapping arm positions are taken into account. The control geometry takes into consideration the paper types saved in the system as well as the coatings, wet-strength adhesives or pre-printing. In this way quality production without delamination or warping is ensured and the adhesive consumption or the energy consumption due to steam for heating optimized.

 

Area of use

The ELCorruMatic CCM includes the automatic control of all quality-related Corrugator Parameters.

 

Application

The ELCorruMatic CCM is an Automation Network which intervenes in the Corrugator Board Production to control and to  optimize Parameters to Customer Specification.

Function

The ELCORRUMATIC CSM (Corrugator Speed and Splice Module) includes all corrugator settings in regard to speed, bridge quantity and splice synchronization. The productivity module controls automatically via interface to the dry-end and the order management system all machine parameters related to splice speed, bridge festoon as well as splices ejections in regard to the specific orders listed in the order management. All paper qualities, which are entered with their specific characteristics (or groups of them) are automatically selected. Machine speeds between wet- and dry-end sections are harmonized and automatically matched to one another. The effective production output is thereby achieved without any over/ underproduction. The result is productivity increase, minimization of start-up waste and improved rest roll management.

 

Area of use

The ELCorruMatic CSM includes the automatic Synchronization of all quantity-related Corrugator Parameters such as Speed, Bridge Quantity and Splice.

 

Application

The ELCorruMatic CSM is an Automation Network which intervenes in the Corrugator Board Production to control and to  optimize Parameters to Customer Specification.

Function

The ELCorruMatic RSM (Roll Stock Management) records the amount of lineal meterage used for any given order, allowing customers to analyse the amount of material required to fulfil the order and any wastage which occurred during production. The RSM System also provides full data about the remaining lineal meterage on any part used reel, providing customers with accurate statistics to help manage their paper stock inventory. 
As with any system within the ELCorruMatic product range, the RSM System can be used as a standalone system or integrated into any of the ELCorruMatic Systems.

 

Area of use

Roll Stock Management System.

 

Application

The ELCorruMatic RSM is an Automation Network which intervenes in the Corrugator Board Production to manage the Roll Stock.

Function

The WarpMeter is a laser based measuring system which monitors board flatness and allows in-depth analysis based on diverse evaluation methods.This system checks the flatness of the current order and adjusts all machine settings automatically, with the result of board flatness according to presetted requirements. The results can be used online during an order run in close loop control or teaches‘ another production run to optimise parameters.

 

Area of use

The ELCorruMatic WarpMeter is a laser based Measuring System to analyse the Board Flatness.

 

Application

The WarpMeter is part of the ELCorruMatic Automation Network, which intervenes in the Corrugator Board Production to control and to optimize Parameters to Customer Specification.
