Automation

In injection molding today, automation is the key to better quality and cost-efficiency. As it becomes more and more flexible, even custom molders are turning to automation for its inherent competitive advantages.

These advantages include:

  • Greater Precision
  • Faster Speed (cycle time)
  • More Flexibility
  • Ease-of-use

From advanced 6-axis servo robots, to our powerful RISC-based distributed-intelligence controller, to fully automated cells, Engel's track record of building part-handling systems for machines from 28 to 4000 US tons is enviable. And with more than 5000 robots in operation, every system we've built is backed across North America and around the world.

ENGEL ERS SERIES ROBOT
Highest speeds for the thinnest lightweights.

ENGEL ERC 23 - 53 E (alternative options EA and EH) - Fast and flexible

  • Rated for injection molding machines with clamping force of between 400 kN and 7,000 kN
  • Available with a choice of three different drive variants:
    • Asynchronous servo drive (EA) for long and medium cycle times
    • Servo drive (E) for fast total cycle times (highly dynamic)
    • High-speed digital servo drive (EH) for extremely fast parts removal (demoulding times as fast as 0.5 sec where the total cycle time is only 5 sec).
  • Precision and repeatability within a tolerance of +- 0.05 mm
  • Machine/robot mounting interface on stationary platen.
  • Molded parts can be deposited either on the front or on the rear side of the injection molding machine, or, if the robot is installed so as to operate in the longitudinal machine axis, at the end of the machine.
  • Modular system for flexible adaptation of axial length.
  • Compact design ensuring low overall machine height.
  • Vertical axes also available in tandem arrangement, if required.

ENGEL ERC 63 - 83 E, EH - The Power Class

  • Rated for injection molding machines with clamping forces of between 2,500 kN and 18,000 kN.
  • Particularly sturdy mechanism for the handling of weights up to 30 kg.

Servo drive (version E)

  • Linear speeds of up to 3 m/s when handling a working load of 30 kg.

High-speed version (EH) with digital servo drive capable of linear speeds of 4 m/s when handling a working load of 20 kg.

  • Precision and repeatability within a tolerance of +- 0.05 mm, like the ENGEL ERC 23 - 53, hence suitable for insert-placing and assembling operations.
  • All ENGEL ERC models are generally compatible with such cycle time reduction methods as advance response, synchronized positioning, parallel operation etc.

ENGEL ERC 93 - 143 E - The power package for large injection molding machines

  • Rated for use on large-capacity machines with clamping forces upwards of 13,000 kN
  • Axes amply dimensioned for extreme stability
  • Low construction
  • Servo motor drives only
  • Telescoping vertical axis as standard
  • Helical rack-and-pinion drives, sturdily built and permanently lubricated for low-noise operation
  • Special sequence control software for the synchronized operation of robot and machine -
    - a valuable cycle time saving feature when demoulding "deep" parts.

ENGEL ELi SERIES ROBOT
HLI Robot: Designed specifically for the tiebarless machine concept

Integrated handling robots for
tiebarless injection molding machine: ER-HLI
For standard "pick and place" applications on Engel tiebarless machines within the 200 to 6,000 kN range, the ENGEL ER-HLi robots represents a low-cost means of automation. The ER-HLi robot is used in cases where molded parts cannot be gravity-discharged from the mould because they are still hot and easily damageable, or in cases where the parts are to be packed directly at the machine. Normally, the ER-HLi robot is mounted on the stationary platen and the parts are deposited on an integrated conveyor belt located within the safety guard. In order to afford ready access to the mould, the position of the conveyor belt can be shifted side-ways in the machine direction. The system can also be optionally equipped with a step-by-step reversing mechanism for clearing the belt when it is full. For multi-color machines equipped with vertical injection units, the ER-HLi robot can also be mounted on the moving platen. The Z-axis of the ER-HLi is freely position able by means of a servo motor, which means that the molded parts can be deposited on the conveyor belt in rows. Separate positioning of the parts according to quality criteria is also possible. The control system is completely integrated in the machine's control system and can be set and adjusted via the machine's VDU. The robot settings are stored together with the machine settings on the same data carrier. By reason on the integrated design of robot and machine, the distances traveled by the gripper and hence also the demoulding times are extremely short. Moreover, such cycle time reducing functions as "Advance Response" "Parallel Ejection" can also be used to speed up the demoulding time still further.

High Speed parts-removal robots: ERS (Speedy)
Nowadays, product development is generally manifesting a markedtrend towards increasingly thinner and lighter parts - and increasingly faster production times.

The answer to this trend - in terms of automation - is the ERS. This high-speed parts-removal robot has been consistently designed for the handling of thin-wall or thin-section parts and for use in conjunction with fast-cycling injection molding machines.

The characteristic working principle of the ERS (Speedy) consists in the lateral removal of parts from the mould by means of a high-speed linear axis. This axis can also be combined with a rotary or swivel axis. The highly dynamic servo motor and the use of high-strength, low-weight materials together guarantee the very shortest demoulding times.

The ERS (Speedy) series is specifically distinguished by the following performance features:

  • Suitable for total cycle times of less than 5 sec.
  • Minimum demoulding time is 0.3 sec.
  • Linear speeds of up to 8 m/s are possible
  • Max. acceleration 150 m/s², that's approx. 15 times faster than acceleration due to gravity!

The "Speedy" high-speed parts-removal robot can be readily combined with such Engel peripherals as the Engel Tray server, converting a fast-cycling injection molding machine, for example, into a fully automated high-speed production cell.
