Dance of the Robots

Pipette tips are small and relatively simple components that are now in high demand. One might think  producing large quantities of these products is a simple task. It is not. The requested high quality can only be reached by using complex automation. To meet these challenging requirements, MA micro automation has developed a modular solution: Centauri IVD.

The Centauri IVD production system can be adapted to meet specific pipette tip manufacturing requirements.

Optimized Motion Planning for Shorter Cycle Times

Injection, holding pressure, cooling phase – injection molding is a sequential process with individual steps that are usually optimized. Therefore, they offer little more potential for improving the cycle time. But what about the automation system?

With the synchronous motion function, the gripper of the robot starts faster, saving valuable cycle time.

Synchronous Motion Shortens Demolding Time up to 35 %

The diverse nature of industries and their requirements is something that suppliers of automation solutions also have to take into account. ''Adapted automation'' is the magic word, because widely ranging batch sizes, an increasing number of product variants and short product lifecycles typify many markets today. Plans for attractive, innovative universal solutions are hidden away in many drawers. Now is the time to pull these plans out and make them a reality.

Industry in a State of Flux: Batch Size Is Everything 

Compared with 2010, the year of the last K fair, sales of robot systems doubled. By the end of 2013 the French supplier of robots and automation systems for plastics injection molding expects to sell more than 1,500 units. 

Sepro Robotique: Automation with Growth Spurt 

Beck Automation invented a new system to label plastics parts that is pending patent approval. Its special twist is the option of using a reduced opening stroke on the injection molding machine. For this purpose, the parts are rearranged in the mold after demolding. The process was introduced to the public at the U.S. plastics trade show NPE at the end of March, reducing the cycle times and costs of the production process, and stepping up output quantities for the packaging industry.

Rearrangement in the Mold 

At present, two automation trends are in evidence among plastics processing companies: On the one hand, the complexity of systems is increasing, while on the other, customers are seeking flexible solutions owing to ever faster product changes, increasing version diversity and, consequently, ever smaller unit volumes per order, down to one-off parts. This means, for example, that high-volume products can be individualized as one-off parts in a flexibly automated, digitally integrated production system by combining injection molding, generative production and "Industry 4.0" technologies.

Automation in Injection Molding: More Control and Flexibility in Production 

Error-Free Coupling 

The vision for the smart factory is that the various components of the production cells will be permanently self-optimizing – distributed intelligence is a prominent feature of "Industry 4.0". For injection molding operations, this means that the focus is widening from just the molding machines to the entire production cell, including the automation. A new generation of linear robots is now capable of reacting to external influences in real time.

New Kinematics for Increased Efficiency and Availability

The pic A Is the First Pneumatic Sprue Picker to Operate with a Swivel Arm

Besides custom-made automation solutions, there is also increasing global demand for standardized robots.  In many automation projects, they help to achieve a combination of high performance and high cost-efficiency. With the new pic A pneumatic sprue picker, the market now has a flexible, compact solution for separating sprues, and easy removal of small injection-molded parts.

Besides custom-made automation solutions, there is also increasing global demand for standardized robots. In many automation projects, they help to achieve a combination of high performance and high cost-efficiency. With the new pic A pneumatic sprue picker, the market now has a flexible, compact solution for separating sprues, and easy removal of small injection-molded parts.

At its premiere at K 2019, the pic A robot broke two records at once. Engel Austria GmbH, Schwertberg, Austria, declared that its goal with the new development is to place the most durable and compact sprue picker on the market. With regard to compactness, the first feedback has already been received from the market. Trodat, an international manufacturer of sophisticated stamp products based in Wels, Austria, has a great deal of experience with handling equipment from Engel. The injection-molding machines in its factory are equipped with type ER-USP sprue pickers. Last fall, it purchased its first sprue picker of the new pic A type (Fig. 1).

“The very compact construction with the innovative kinematics gives us a clear advantage,” reports Thomas Dobritzhofer, Head of Maintenance and Facility at Trodat Produktions GmbH in Wels. “We can fold in the robot arm completely and therefore no longer need to swivel the sprue picker out of the way for mold exchange. That significantly speeds up the mold set up.” Trodat is now successively replacing its former sprue pickers with the new pic A generation.

Fast and simpler set-up processes contribute to increasing the availability of the injection molding machines – a factor that is essential to its efficiency and competitiveness. When the swivel  arm is in the park position, the pic A frees up the entire mold mounting space. Conventional sprue pickers with a fixed X-axis would have to be dismounted or displaced to achieve this (Fig. 2).

In the pneumatic sprue picker segment, the pic A is the first robot to work with a swivel  arm. It is only with this innovative kinematics that all interference contours can be eliminated. “At first, the swivel  arm was not intended for use with this robot type at all,” says Gerald Huber, who was responsible for construction of the new sprue picker at Engel’s robot factory in Dietach, Austria. The developers approached the goal via different design concepts (Title figure).

For example, a linear kinematics, which would be able to move out of the way behind the fixed platen was evaluated. This concept was rejected since many applications need this space for peripheral systems or additional injection units.

The inspiration for the swivel  arm was finally provided by e-pic type robots. This servoelectric sprue picker from Engel is also highly compact thanks to the swivel-arm kinematics.

As with the servoelectric models, the swivel  arm of the pneumatic robot is responsible for movement in the X-direction, and thereby replaces the fixed X-axis (Fig. 3). Though looking unusual, it proves very easy to operate, since the triangular kinematics converts the vertical drive movement into a horizontal, linear demolding movement. The tool setters and plant operators therefore do not need to change the way they work.

Since the fixed X-axis is eliminated, the pic A is also particularly space saving in continuous operation. In confined molds, too, the swivel  movement is very reliable and precise. The demolding stroke is continuously variable up to a maximum stroke of 400 mm, which sprue pickers with conventional kinematics cannot manage.

Another new feature is that the Y-axis module can be adjusted with just a few manipulations. The rotation range of the A-axis can be flexibly adapted between 0 and 90° to suit the particular requirements (Fig. 4).

The pic A is fitted with a very sturdy mechanical system to achieve a long useful lifetime. The demolding stroke is particularly torsion-resistant, and the impact is additionally damped by adjustable sliding rails.

The maximum manipulation weight at the end of the Y-axis is 1 kg. To rotate and eject relatively large sprues, a B-axis can be optionally placed between the Y-arm and sprue gripper. Overall – depending on the end-of-arm tooling – both sprues and small injection molded parts weighing up to 0.5 kg can be manipulated.

Standardized Operating Logic across the Entire Cell

When used on an Engel injection-molding machine, the control system of the pic A, like the control systems on all other Engel robots, is integrated into the CC300 control system of the injection-molding machine. The greatest benefit for the user lies in the fact that the machine and sprue picker can be centrally and uniformly operated from the machine display. The standardized operating logics reduces the required training for the new robot generation, thereby further increasing the overall efficiency.

In this integrated solution, the sprue picker is supplied with power via the injection molding machine. It can be very easily commissioned by plug & play, since, in this solution, the mechanical connection in this solution is also from a single supplier. The sprue shaft  is compactly integrated into the injection-molding machine and is part of the CE safety certification (Fig. 5). Since the ER-USP predecessor model and the pic A use the same discharge chute and the same interface, existing injection molding cells can be very easily refitted with the new model. The sprue picker is compatible with all Engel injection-molding machines from the control generation CC200.

As a pneumatic sprue picker, the pic A fulfils the strict EN ISO 10218 robot standard with performance level d/category 3 and is already comprehensively designed for two-channel switch off. The demolding stroke can be easily and reliably adjusted with only one hand. For this purpose, the pressure is automatically reduced during set-up mode. Set-up mode is activated as soon as the safety gate of the injection-molding machine or the door of the safety guard is opened.

From cutting off and separation of sprues via product removal and deposition, through to a highly integrated, interlinked manufacturing process, Engel developed individual automation concepts for a wide variety of injection molding applications. The basis for this was a comprehensive portfolio of robots and a high level of special automation expertise. This is essential for developing solutions that perfectly meet quality, efficiency and cost-effectiveness requirements without providing additional functions that are not used.
