ATM, the UK robot manufacturer, continues to produce a full range of Cartesian Robots that are seen as a mainstay of the plastics industry in the UK.

ATM Cartesian Robots perform a multitude of part handling, de-moulding and insert loading tasks, as well as packaging and palletising operations at the end of the production line.

All but a few of the robots produced by ATM are fully servo-driven systems, with the latest models providing the reliability and performance needed to achieve high uptimes and output.

ATM’s Cartesian Robot range starts with the ES500, a compact robot driven by AC servo motors with a work envelope of 1500mm x 400mm x 800mm (X,Y,Z).

This robot is capable of handling an 8kg payload at speeds of up to 4m/s.

The larger ES1000 and ES2000 robots provide greater working ranges and payloads – 2000mm x 650mm x 1000mm (X,Y,Z) with a 10kg payload for the ES1000, and 2500mm x 1000mm x 1500mm (X,Y,Z) and a 12kg payload for the ES2000.

Speeds of up to 4m/s can be achieved by the ES1000, with the larger ES2000 capable of achieving speeds of up to 2.5m/s.

For extremely large working ranges and heavy payloads, the ES3000, the largest of the ATM range, can be configured with customised strokes, enabling this model to be used with even the largest injection moulding machines and handling payloads of up to 40kg.

ATM has recently introduced linear motor drive technology to its side entry robot systems.

Used in applications where the moulding cycle is very short, generally three to five seconds, side entry robots need to be extremely fast to minimise the tool open time and maximise the output from the moulding machine.

Where traditional rack and pinion/belt drives and ball-screw systems are reaching their limits at de-mould cycles of around 1.5 seconds, linear motor drive technology allows de-mould cycle times of

To realise the maximum benefits available from this technology, it is essential that gripper design, concepts and materials are matched to the performance of the robot.

ATM is able to produce gripper systems that enhance the overall capability and performance of the robot system.

Using lightweight materials such as carbon fibre minimises the robot payload and enables the robot to achieve the fastest possible cycle times.

ATM high-speed side entry robots are not only used in a stand-alone configuration, they can be integrated with other robots and automation as part of a complete production cell.

For example, when used in conjunction with an ATM six-axis robot, it is common for the side entry robot to be driven and controlled by the six-axis robot controller.

By effectively adding the side entry robot as an additional axis to the main robot, the side entry robot becomes fully integrated and programmable from the six-axis robot teach pendant.

ATM side entry robots using linear motor technology can be used to reduce cycle times in a wide range of applications including injection moulding and packaging.

All of the robots within ATM’s ES range are controlled using a PC-based control system, with operation and programming made simple using the touch-screen hand-held pendant.

ATM Automation also provides six-axis and seven-axis robot systems, plastics joining technologies, gripper and tooling systems, and complete system solutions.
