Ball sensing machine is designed for inspection of correct size of the
ball in the bell assembly. This machine is compact with self-contained
control panel. Error free sequential operation is ensured with the help
of positive feedback interlocks interfaced to the PLC. All the co-ordination
movements are performed with the help of pneumatic actuators. This machine
consists of the following sub systems:
basic structure consists of fixture for loading and locating the component.
A pneumatically operated clamping mechanism for positive clamping in the
fixture. Rotary cylinder to verify the presence of slot in the bell assembly.
Six numbers of LVDT’s are provided on the bottom side of the fixture
to inspect the correct size of the balls in the bell assembly.
control system is based on industrial standard and highly reliable programmable
logic controller (PLC). It controls the operating sequence of the various
operating elements with the help of feedback inputs. The associated electrical
control & safety circuits suitably support the control subsystem.
