ZoneControl Series is Industry’s First Complete Solution for ZPA Conveyor Applications
MINNEAPOLIS – June 3, 2003 – SICK, the global leader in factory and process automation solutions, announced today its complete family of zero pressure accumulation (ZPA) solutions. ZPA conveyors used in distribution warehouses, logistics centers and work-in-process operations are designed to accumulate and release product with zero forward pressure, resulting in a decreased risk of product damage or derailment.
By using the complete solution, ZoneControl from SICK reduces costs while providing maximum usability. · Modularity – ZoneControl from SICK is the only solution to accommodate all types of accumulation conveyors by utilizing a variety of mounting configurations.· Flexibility – the intelligent logic circuitry can be manipulated with integrated switches and external inputs, allowing the user to easily change the conveyor functionality as needed. · Reliability – Use of non-contact sensing devices, high quality components and the superior design of the ZPA control system all increase the reliability of the system. · Cost Reductions – ZoneControl solutions are off-the-shelf bundled solutions that meet specific applications solutions, reducing the number of individual components needed in a ZPA application, thereby minimizing costs, installation time and reducing wiring demands.
ZoneControl™ from SICK is the industry’s first complete solution, offering multiple sensing solutions and mounting configurations, as well as all the necessary accessories and peripherals. The ZoneControl family provides single and slug accumulation as well as single and slug release solutions, providing the flexibility to use multiple methods of ZPA solutions. The family also consists of integrated ZPA systems designed to accommodate different types of accumulation conveyors by utilizing a variety of mounting configurations, including over-the-conveyor (WLR), under-the-conveyor (WTR 1) and side-frame-mounted (ZLM 1). The WLR solution mounts above the rollers for a more traditional mounting configuration.
The WLR uses an industry standard mounting and fits into existing brackets for simple replacement. The WLR is an integrated ZPA control system containing the photoelectric sensor, ZPA logic circuitry, daisy chain cabling and a cable connection for the solenoid valve (valve not included). The WLR polarized retro-reflective sensing technology has a nine meter sensing range with crosstalk immunity, so reflections from nearby sensors will not cause false triggering.The WTR 1 solution mounts under the conveyor and between rollers. This mounting configuration protects the sensor from damage, which reduces replacement costs.
The vertical optical orientation eliminates the need for periodic cleaning of the sensing face. The WTR 1 is a completely integrated ZPA control system composed of a photoelectric sensor, pneumatic valve, ZPA logic circuitry and daisy chain cabling. It senses in proximity mode, eliminating the need for a reflector. The WTR 1 sensing technology provides adjustable background suppression to optimize detection of low profile and dark colored products, while completely ignoring the conveyor side channel in the background. The ZLM 1 solution is a logic module designed to mount on the side frame of the conveyor, either under the conveying surface or on the outside.
The logic module allows connection of any small sensor, which can be imbedded in the conveyor frame or side guard, protecting it from potential damage in shipping to the end user and in everyday use. The ZLM 1 is an integrated ZPA control system containing the pneumatic valve, logic circuitry, daisy chain cabling and connection for remote mount sensor (sensor sold separately).SICK is a worldwide manufacturer of factory and process automation solutions.
