Sepro targets demanding production with S5 robot

Hall 12/A49 French robot maker Sepro Robotique will have its largest ever display at this K, including its new Multi-Inject robot for multi-component moulding applications and the S5 high performance beam robots, and six-axis robots. The vertical injection unit on a multi-compo- nent injection machine can interfere with movement of a standard beam robot, says Sepro. It has developed its Multi- Inject 20 robot to overcome this problem. It will be demonstrated on a 210-tonne Sumitomo Demag machine using a rotary mould making ice scrapers with soft-touch gripping surfaces. The robot will also place a decorative label in the mould prior to injection of the soft-touch material and removes the finished component. l A 60 tonne Arburg machine will be operating with an S5-15

before moving the finished parts outside the moulding area where the car is press-fit assembled. l Two 6-axis articulated-arm units complete the display and will be shown operating together with three

5-axis beam robots.

robot, the smallest model in Sepro’s line of high-perfor- mance 3-axis servo-driven units. The robot will be presented in an axial configu- ration with a horizontal beam running parallel to the injection unit. This cell will produce a toy car with wheels on metal axles. The robot picks the axles from a feeder and places them in the tool. The robot then removes the components and places inserts for the next cycle

Developed by Sepro in partnership with Stäubli Robotics, these two robot families are aimed at injec- tion-moulding applications requiring complex part manipulation. The 5-axis 5X Line is based on high-precision Sepro 3-axis beam robots with a 2-axis Stäubli servo wrist. The 6X Visual line of robots combines a Stäubli 6-axis articulated- arm robot with Sepro’s easy-to-use Visual 3 control. l The company will also demonstrate its all-servo driven S3 sprue picker. ❙

Compact de-duster system

Hall 11/G57 Pelletron will launch the C-20 dedusting unit at the show, a compact unit designed specifically for the injection moulding market. The new model is designed to remove dust and streamers from the feed stream, helping avoid black spots and other contaminant-based effects in parts. It uses the same technology as the com- pany’s larger dedusters, with an agitator in the inlet to prevent product bridging and energy efficient venturi system carrying away dust to a collector unit. The unit measures just 240mm high and weighs less than 9kg, making it easy to install beneath the machine hopper. It features a stainless steel construc- tion and offers a flow rate of 20 kg/h at a bulk densitry of 560 kg/m3

. ❙ Koch launches new doser

Hall 10/A21 Materials handling systems maker Koch-Techik will show the latest version of its Graviko gravimetric dosing equipment, together with its Navigator automatic feed system. The GK 65 provides a

throughput of up to 70 kg of plastic an hour and is the first Graviko unit to use two synchronous load cells for

more precise weighing. The basic version weighs up to three material components alongside the main component in its internal, vibration-free weighing container. The new synchronous

set-up weighs each fill one hundred times in succession, registering the values and transferring them to the control unit, which the

company says compensates for any fluctuations. Once all values match, the dosed batch is emptied into the mixer where a horizontal agitator homogenises the blend. The unit can be integrated with Koch-Technik’s Navigator fully automatic feed system, which can distribute up to 40 different materials. ❙
