FlexiBowl employs circular band tracking to simplify and speed the robotic acqui- sition of component parts used in assembly, handling and kitting applica- tions. The unit can quickly separate and orient a variety of parts made from diverse materials including plastic, metal, rubber and silicone.
“Unlike traditional vibratory bowl feed- ers, which have limited flexibility due to their high level of customization,” says Adept president and CEO John Dulchinos, “the FlexiBowl utilizes vision technology to create a truly flexible, standard parts- feeding solution that can be deployed and redeployed quickly, eliminating the time, cost and complexity associated with traditional parts feeding.”

Servo-Electric
Pump Drive
Optimizes Hydraulic
German hydraulic-press builder Lasco Umformtechnik GmbH introduces a hydraulic pump directly coupled with a ser- vomotor as an energy-efficient solution to “provide substantial energy savings for companies operating our presses,” says Harald Barnickel, the firm’s head of electrical engineering. At the core of the drive package is a Simotics 1PH8 ser- vomotor from Siemens, which directly drives the hydraulic pump. With a response time of 250 μs, up to 256 axes can be synchronized and precise axis motion and curve profiles executed.
Plunger speed is controlled by motor speed and thus by the volumetric flow rate of the pump. Four axial reciprocating pumps, with a fixed displacement per rev- olution, are connected simultaneously for a maximum pressure of 250 bar, to supply the pressure line for the press stroke of the plunger. Three additional pumps are responsible for the return stroke of the press plunger.
The press’s hydraulic oil tank holds 9000 l, and because of the high flow rate of 16,000 l/min., filling valves are used
for the fast downward motion of the plunger. The servo pumps provide the required flow rate for the actual pressing opera-
tion, with a speed of up to 100 mm/s. Previously, high-precision control valves with zero overlap were required to
