UBT XenoBRAKE
A XenoBRAKE designed for use with UBTs provides
clearance for the transfer belts. It is a low cost
alternative for stopping product on a UBT. The
XenoBRAKE mounts to the inside of the side
channel between the channel and line-shaft
assembly. The roller on each end of the UBT is
slave driven from the adjacent roller so all rollers
stop.
The UBT XenoBRAKE applies to all types of UBTs:
standard, bi-directional and opposite direction. The
double wide standard UBT with split rollers will
require two XenoBRAKES.
Placing a XenoBRAKE in a UBT may also provide
another accumulation zone in addition to those
between transfers. This requires fewer indexing
controls and no loss of queue position at each
transfer.
When transferring off, a pneumatic time delay can
be added on the up cycle between the lift table and
the XenoBRAKE cylinder. The XenoBRAKE will
stop the product before the transfer belts rise and
both the XenoBRAKE and the transfer belts lower
together.
PIVOTING ROLLER STOP
The stop has a gravity roller which raises above the
powered rollers when activated. The arms which
support this stop roller pivot causing the roller to fall
away from the product when retracted. A minimum
length bed of 2'-0" is required for attaching. A
crossmember cannot fall within the stop frame. The
stop roller may replace the roller adjacent to a
crossmember on the upstream side.
Recommended air pressure is 60-80 PSI. Maximum
product weight should not exceed 80 lbs. at 60 FPM.
Accumulation held by the stop should not exceed
30'.
Pivoting roller stops are normally received
preassembled, separate from the bed they are to be
installed into. The powered roller which will be
replaced by the pivoting stop roller must be removed
from the conveyor bed. At least two rollers will need
to be temporarily removed over the pivot point of the
arms. Before the stop assembly is bolted into place,
remove the top half of the split collar on both sides
of the pivot arm assembly and remove the assembly.
Bolt the remaining portion of the stop into place
between the frame of the conveyor and insert the
bracket back into place above the line-shaft
assembly. Now replace the top half of the split collar
and reinstall the rollers above the pivot. Adjust the
lift arm when in the down position so that the gravity
stop roller is flush with the other bed rollers. This is
accomplished by loosening the jam nut on the air
cylinder and turning the rod until the proper height is
achieved. After this adjustment is made, retighten
the jam nut. Complete the assembly by connecting
air lines to the double acting cylinder and the
actuating controls.
In addition to the air operated pivoting roller stop,
foot and hand operated stops are also available.
The foot operated product stop uses a cable to
connect the foot pedal to an eye bolt on the pivot
arm. This foot pedal must be bolted to the floor
directly under the product stop. Hand operated
models use an offset handle to the outside of the
conveyor frame which directly attaches to the lift
arm.
