7-INSTALLATION AND OPERATION (continued)
Box Release Timer:
The Box Release Timer, shown in Figure 7-6, is
located below the conveyor bed at the infeed end of
the conveyor. The timer controls the box stop gate
that releases the boxes to the a80f-if case sealer.
The timer is adjustable for box lengths from 15mm
[6 inch] to 635mm [25 inch]. The timer must be
reset for each change in box length being conveyed
through the a80if case sealer.

Pneumatic Components Function
The air supply operates the adjustable pneumatic
timer and powers movement of two air cylinders that
raise the non-powered box rollers to release one
box for the tape sealing application. The box cam
activates the same two air cylinders that lower the
box rollers and the stop gate retains the next box
from moving forward.
Electrical Components Function
A motor, reducer and drive chain turn the powered
box rollers that convey the box forward for the tape
sealing application.
Operating Sequence
1. The operator places one product fi lled box
(front and rear fl aps folded in) onto the infeed
conveyor non-powered box rollers (in the up
position) and moves it forward to the stop gate
as shown in Figure 7-7.

Note: A precision regulator is used to balance
the top drive assembly. Due to the self-
relieving feature of this regulator, a small
amount of air continually vents to the
atmosphere. This is normal and amounts
to approximately 3 litre/min. [0.1 SCFM].
For compressed air supply Technical Specifi cations,
• To reduce the risk associated with
entanglement and electric hazards:
− Keep hands and loose clothing away from
moving rollers
− Remove tools and/or other loose objects
before starting conveyor
− Turn off and disconnect electrical and
air supply power before performing any
maintenance or service work on the infeed
conveyor
• To reduce the risk associated with
impact hazards:
− Always turn the valve "Off" when air supply
line is being connected or disconnected.
