SCHUNK CPS Automatic Tool Changers

Automatic Tool Changers - What Are They & How Do They Work

Pneumatically actuated tool changer with self-retaining function in the event of a loss of compressed air, the integrated piston spring ensures that gap formation is minimized.

A changer for every robot

The CPS automatic tool changer is the flexible solution for fast and reliable tool changes.

The change master and adapter have a process reliable connection via a self-retaining locking mechanism, which is designed for handling weights of up to 1,000 kg.

Thanks to its hardened steel components, the CPS is ideal for demanding environments, such as those frequently encountered in machine loading or machining. With 18 sizes, the CPS offers the right model for every robot.

Existing SCHUNK tool changers can be easily replaced by the CPS without the need for re-teaching.

Advantages – Your benefits

➕ Wide range of sizes

with 18 sizes, the CPS enables an optimal selection for every application

➕ Versatile media transmission
extensive range of optional modules for feed-through of electrical and fluidic media extends the application possibilities of the tool change system

➕ Durability
The use of hardened and stainless steel in all functional parts increases the bearing load capacity and extends the service life

➕ Easy assembly
Installation is quick and easy using standardized adapter plates or directly on the mechanical interface

➕ Consistent compatibility
Thanks to full compatibility with SWS change masters and adapters, existing applications can be expanded or replaced on a 1:1 basis using the CPS system.

Sectional diagram

The automatic tool changer CPS consists of a change master (CPS-K) and a change adapter (CPS-A). The CPS-K that is mounted on the robot couples and decouples the CPS-A which is mounted on the tool. The pneumatically actuated locking piston ensures a reliable connection. Suitable option modules supply the coupled tool.

1.  Housing - Weight-optimized due to the use of high-strength, hard-coated aluminum alloy

2.  Piston - Pneumatically driven, ensures locking/unlocking of the system

3.  Locking mechanism - Functional parts are made of hardened stainless steel. Locking balls ensure a quick and secure connection. Self-retaining during compressed air drop. Integrated spring prevents gap formation between master and adapter.

4.  Integrated pneumatic feed-throughs
- Minimization of the interfering contour. Also suitable for transferring vacuum.

5.  Sensor monitoring of the locking device - Optional, for monitoring in a reliable process
