General Information
The ALPS FlexPitch Multi-Moving head leak tester provides high speed leak testing of a wide
range of bottle types including shingling, reverse-taper, and small bottles which are traditionally
difficult to test. The FlexPitch has a smaller footprint to perform leak testing on an existing
conveyor line, requiring no conveyor line modifications. The FlexPitch has built in flexibility with 2-
4 test heads for a variety of container sizes up to 350oz. This makes the FlexPitch ideal to leak
test difficult containers. The FlexPitch Multi-Moving head leak tester provides tool-less
adjustments and no formatted parts to change, making quick bottle changeovers. The FlexPitch
uses servo motors and linear slide combination coupled with an encoder (mounted to the top of the
conveyor) to track the conveyor movement and speed. As molded bottles enter the machine, the
Multi-Moving test heads locate and leak test each bottle. After the test is completed, good bottles
pass through machine, and defective bottles are ejected off the conveyor line with a reason
displayed on the HMI.
A single electrical cabinet is installed on the backside of the machine containing the AC power
circuits, servo motor drives, DC power supplies, power contactors, and main disconnect. The
control system features a multi-channel PLC and color touch screen interface with an intuitive,
icon-based menu structure. Standard features include an integrated Self-Test feature for each
station.
