Better
accumulation and less product damage; accumulate both cases and
poly bag loads, zone-free
EZ Logic Accumulation Systems combine a system of
photo-eyes and discrete electronic logic control without the use of PLC? to
provide "intelligent" zero-pressure control. Paper and Pulp Converting
mills benefit greatly from the ability to accumulate both
cases and poly bag loads on conveyor lines, zone-free.
This system works on a
variety of conveyor models, and allows you to customize how the product is
accumulated and released from the conveyor. EZ Logic allows for programmed
functioning of individual zones within the length of conveyor. This provides for
customization of the manner in which product is accumulated to suit the
requirements of the system.

Two modes of operation: Singulation mode and Slug mode:
Singulation mode: product separates while traveling down the conveyor and when
it is released from the conveyor, creating a zone-length gap between packages.
This mode is comparable to normal accumulation using pneumatic accumulation
logic. Slug mode: product does not separate when traveling down the conveyor or
when it is released from the conveyor. This allows higher carton throughput.
Built-in " Zone Stop" function:
EZLogic allows the connection of dry-contact-type switch devices such as a
toggle switch or relay. Closing this contact activates the zone stop function.
The next product sensed by the module stops and holds until the contact is
opened. Packages arriving from the upstream direction from the stop zone
accumulate in sequence. This feature is always used at the discharge end of the
conveyor line, and may be used at any other location where a zone stop is
required.
Jam protection: In slug mode, if a package is
sensed for six seconds or longer a signal is sent to the upstream zone to
accumulate product on the upstream side of the jammed package, preventing
product pileup until the jam is cleared.
"Sleep" Feature: If EZLogic does not
detect the presence of product for a selectable time period, the module stops
the zone from driving. This reduces noise and roller wear. Packages traveling
down the conveyor wake up the zones as needed to move the package.
Special delay timer functions: Timers are
included to provide delays in product accumulation and/or restart in certain
situations. These timers may be used to enhance product flow, to provide for
conveyor-unloading operations, and to provide added flexibility.
Plug-in connections: Each EZLogic accumulation
module has a cable terminated with a sealed female connector and a keyed male
connector integral with the module body. This cable provides power to all the
modules on the conveyor as well as communication between modules. Other input
and output connections use integral sealed cables and plug-in connectors for
true plug and play convenience.
Push-button programming: Various EZLogic
features may be enabled, disabled, or adjusted by using two push buttons located
on each module. These allow the selection of solenoid output mode, jam
protection enable/disable, sleep mode enable/disable, sleep timer settings,
singulate/slug, special timer settings, and diffuse sensing range.
"Clone" and "Reset" functions:
Settings for various features may be programmed into one module, then cloned to
all modules in the chain upstream from that point. This eliminates the need to
program each module individually.
