MERGE ASSEMBLY
Merge assemblies are used at the juncture of two
conveyors where one is required to merge into and
join the other line. The merge assembly consists of
an abutting bed, spur and power connection. Both
conveyors are joined together using a common drive
through the power connection. The power
connection consists of a jump chain in the abutting
bed joining a second shaft on the spur side which
contains two universal joints to connect with the spur
at 45 degrees.
Normally the merge assembly requires either a pivot
wheel mounted at the juncture of the spur in the
abutting bed or a curved wheel rail. Either of these
accessories will guide the product onto the abutting
bed, giving the product something to pivot against
during the transition.
Curved Wheel Rail
Pivot Wheel
While the product is merging, it is being pushed by
the spur and pulled by the abutting bed. The bottom
of the product is forced to slide on the rollers as it
pivots on the curved wheel rail or pivot wheel. The
resistance of this sliding causes the capacity of the
merge to be less than the equivalent straight
conveyor. This difference is compensated for by
utilizing 1/4" diameter belts in both the abutting bed
and spur. In addition to the added drive capacity
due to the larger diameter belt, it is recommended
that the spur be mounted 1/4" higher than the rollers
in the abutting bed to delay the pull of the abutting
bed until the product is driven further onto it. The
bolts holding the spur to the abutting bed will have to
be loosened in order to reset this height since the
merge assembly is shipped with the abutting bed
and spur at the same elevation.
Merge assemblies ready for shipment. Preassembled with
connecting power and spur guards (shown upside down).
SPURS
In some applications the power connection of the
merge assembly is not needed. The spur is then
driven from a different motor. In this case the
abutting bed is ordered as an intermediate bed and
the spur is ordered separately. The specific
intermediate bed serving as the abutting bed must
be specified with additional drive capabilities. This
also means there will be no pre-existing mounting
holes between the spur and the intermediate bed.
These holes must be drilled at installation to make
the spur connection.
Without a power connection to the main line, spurs
may be placed anywhere along the abutting
conveyor length.
To install the spur:
1. When product is diverting to the spur, mount
the spur so that the rollers of the spur and
abutting bed are flush. When product is
merging from the spur, set the spur height so the
rollers of the spur are approximately 1/4" higher than
the rollers in abutting conveyor.
