Operator Maintenance
(Autonome Instandhaltung) goes 
digital

Company:

Allgaier Group

Solution:

mHub X
Maintenance Edition

The Challenge

Until now, the Autonomous Maintenance (AIH) at the Allgaier Group has been carried out and documented using paper-based checklists. Detected defects were communicated and processed using so-called defect cards. The archiving of the results took place in the form of loose paper collections. 

 

Autonomous maintenance, also known as operator maintenance, includes the regular and systematic cleaning of the equipment by the production staff in order to ensure the functionality and service life of the systems in the long term.

 

The Solution

By using nuveon's mHubX Maintenance Edition, the AIH is now carried out completely digitally and with intelligent support.

The employees who carry out the cleaning and testing activities during the system shutdown are navigated to the respective maintenance points via a tablet. Once there, the stored safety and cleaning instructions must be read and confirmed. In addition, corresponding images depicting each cleaning point are available to help the employee with quick identification of the physical maintenance point.  A visual target / actual comparison can thus be carried out directly in the system!

In the event of a defect, the maintenance point is marked as "defective" and described in detail in a text field. If necessary, a photo or video can be loaded into the application or maintenance point via the tablet's camera. If there are no abnormalities, the maintenance point is concluded with "no defect".

In the so-called "Maintenance plan" view, the respective system is displayed with all of its defined maintenance points. The checkpoints that have already been processed are color-coded and use a red / green logic for n.i.O and i.O. modes. This enables one cleaning cycle with two or more tablets. At the same time, maintenance or team leaders receive a visual insight into ongoing maintenance through a browser on any device.


Once the maintenance run has been completed or if it had to be canceled again, an automated e-mail notification is sent to a predefined distribution group, with the notification that a maintenance run has been completed on the system. The recipients are directed to the evaluation via a link, where all details (e.g. list of defects, duration, etc.) can be viewed.

 

Once the production staff has finished the maintenance run, the defects are processed by the maintenance staff. They too carry out their work completely digitally with tablets. We are talking about so-called "maintenance cases", which can be set to the status "Closed", "In Progress" or "Blocked". An email option is also available with which the maintenance engineer can send and comment on the respective maintenance case to any email recipient (e.g. to order a necessary spare part).

With this new data, different trends in the system wear-parts can be evaluated in the future, which can, for example, indicate a defect in the system's design.

After the successful implementation on a robot component system and presentation to the management, the rollout to all other systems in the areas of component production and the press shop is now being planned.

Benefits

The logging of maintenance work is now much more efficient. Detected problems can be easily communicated and thus resolved promptly.


More reliable detection of defective equipment through visual comparison of "i.O. equipment".

 

Direct and prompt electronic forwarding of repair measures to the maintenance tool (the nuveon mHub platform).

 

Fully electronic documentation and archiving of cleaning and repair measures (including elementary for IATF audits).

 

Evaluations of Trends possible (e.g. increased wear of various system components can indicate a deficiency in the system design).
