Section 5 - Case Infeed and Indexing

Feeding in of cases is an important issue in the efficient operation of automatic case closing. (See manual
for information.)
Infeed conveyors should be level and horizontally aligned. Case should transfer smoothly when pushed
or powered into the machine without changing elevation and remaining level.
A level entry is important as the side belts will grip and hold the case in the same attitude as presented
into the machine. If the level and case angle are incorrect this will go through the process and cause jams
or poor quality closures.
Problem: Case is loosely sealed on bottom
•
Check that case is entering the machine in a level position. If not adjust conveyor and /or machine
height and centering.
Trouble Shooting - Case Infeed Separation / Indexing
Case indexing provides a gating function which ensures that cases enter automatic sealing machines in a
timed manner to prevent jams due to more than one case being in process at one time.
This option is normally used when an accumulation or back log of cases are expected on the infeed
conveyor.
When cases are hand packed it is not normal to need an indexing gate, as they are fed one at a time to the
sealer.
The indexing gate is in the normally up position and provides some squaring assistance as the moving
case strikes the gate. A timer will then drop the gate if the machine is clear and ready to cycle.
Trouble Shooting - Case Indexing Option
Problem: Two cases are in machine at the same time and cause a jam.
•
Check that the gate is powered up and working.
•
Check that the timer is set to a sufficient interval to permit proper separation. A small slot head screw
in the head of the round timer block can be adjusted to change the dwell time.
