Start Up; Shear Gate; Skirtboards; Changing The Conveyor Belt - Siemens milltronics WEIGHFEEDER 1200 Series Instruction Manual

Start Up

Your weighfeeder has been factory run-in for a minimum of four hours; it should require
little adjustment. However, periodic inspections of the belt tracking are recommended.
Start the belt and observe rotation.
WARNING: Turn off and lock out all power sources before
correcting rotation. On DC motors, reverse the armature wires. On
AC motors, reverse 2 of the 3 motor wires.
Start the belt again and observe the machine as it is running. If the belt is not tracking

correctly, see

Shear Gate

The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum
feedrate capacity requested by the customer. Consult your Siemens representative if
feed rate changes are required.

Skirtboards

The skirtboards have also been factory set to proper specifications. Note that near the
inlet, the skirtboards are very close to the belt. However, toward the discharge end of the
weighfeeder, the skirtboards are 1/8" to 3/16" higher off the belt. This tapering improves
material flow and will help the product move down the belt without "bottlenecking."
Adjustments of the skirtboards should not be necessary but if they are required, set the
skirtboards at the heights described above.

Changing the Conveyor Belt

Enclosed Units:
framework is not designed to support the operating weight of the feeder and material
when the access side support legs are removed. Remove the legs only when
removing the belt. Immediately re-install the legs after the belt has been changed.
Support the side of the feeder frame with a fork lift or other support while the access
side support legs are removed.
1. Open and remove the access and non-access side covers (omit this step on open
construction models).
2. Mark the position of the telescopers for reference. This will be handy when you re-
install the belt. Loosen the telescopers to remove tension from the belt.
