Tool handling system

Liebherr automates the handling and storage of tools in sophisticated systems perfect for production environments with multiple machining centers or high tool demand.

Increasing the degree of automation: from automatic workpiece to tool management

In industries with high tool throughput, such as aerospace or tool and mold making, automated tool handling solves key problems. In such cases, it makes sense to add tool automation to automatic machine loading in linked systems.

CHALLENGE

High tool requirements

- Large tool magazines are required
- Large part variance
- Machining of high-strength materials

Limited storage capacity

- Machining centers reach their limits in terms of storage capacity
- Large tool magazines result in additional costs for each machine

Frequent insertion and replacement of tools on multiple machines

- Requires a high degree of organization and effort
- Tool requirements are often queried manually
- Creates waiting times for tools

SOLUTION

Automatic tool change

Our reliable automation system, consisting of a storage and distribution system as well as intelligent resource management, predicts the tool requirements and eliminates waiting times.

Central tool storage

The system provides large storage capacity for several thousand tools. Each system can be adapted to the respective tool requirements, the individual spatial conditions and different mountings (HSK, SK, etc.).

Automatic changing of tools

Enabled by a tool distribution system in the form of a linear or robotic gantry that feeds the tools to the interlinked machines, multiple machines can access the same tool.

The advantages of a tool handling system

Space-saving

A compact alternative to decentralized, scattered storage, featuring individual tool trolleys and cabinets. Helps saves up to
60% of the space.

Reduced personnel requirements

A central point of contact for all tools means that there are no unnecessary searching times. Supports unmanned production.

Increased productivity

Eliminating waiting times ensures shorter throughput times, better machine utilization rates and lower manufacturing costs. Intelligent and predictive requesting of tools, with which requirements can be reported directly to tool presetting.

Cost savings

Thanks to more efficient processes and the central availability of special and sister tools, one tool can be used on different machines. Error costs are reduced by automatic data transmission.

Holistic tool management with Liebherr system competence

Central tool magazine

The Liebherr tool storage system stores tools on shelves with a large storage capacity. The magazine modules can be arranged flexibly and extended, creating storage capacities of several thousand tools. The tools in the storage system are handled by a robot. A separately selectable distribution system is responsible for the transport and changing in of tools into the machining centers. The tools are stored and removed via a feed station in the storage area. There, the tools are identified and the data are transmitted to the cell control.

Distribution system can be flexibly combined

The Liebherr gantry loader LP achieves maximum cycle times. Grippers, axes and compensator equipment, if needed, are adapted to the machine tools in the system. The alternative is a robot portal RP, which provides maximum flexibility and is also suitable for difficult loading situations.

Intelligent cell control

The cell control ensures a perfect overview. It coordinates tool management, including all data, and ensures a continuous flow of information. Error costs caused by incorrect tools or faulty data transmission are eliminated. Resource planning ensures that the necessary tools are available according to need. This produces fewer standstill times and a higher machine runtime.

Automation system independently and proactively reports tool requirements to tool presetting
Only tools that are really needed are ordered
Consistent data avoids collisions, e.g. due to incorrect dimensions
Improved planning
Status of all tools can be called up, tool life monitoring
Interfaces to existing software tools, e.g. CAM, ERP

Complementary products

PHS pallet handling systems

Perfectly suited for variant manufacturing, the Liebherr pallet handling system offers large workpiece storage units and thus long autonomy times in low-manpower or even unmanned manufacturing. Intelligent cell control helps to manage resources and reduce the complexity of high mix/low volume manufacturing.
