Description
The Zed SNT Series is an advanced, inline skin packaging system incorporating the latest in machine design & control systems, featuring many technical innovations and available options to meet the demands of today's skin packaging applications (see below). The SNT Series is manufactured on an extra heavy-duty construction framework utilizing the finest materials and components to insure years of trouble-free operation and maximum productivity.
The operator places a master card onto the infeed conveyor (automatic card feeder available). The infeed conveyor automatically indexes through the product loading stations and into the automatic skin packaging area. The card is then indexed from a cooling station through a hydraulic trim press that trims the master card into individual packages complete with hanger holes, if required. Machine cycle speed is adjustable to pace the operators and product loaders.
Features and Benefits
Electrical
460/480 volts, 3 phase, 60 HZ (other voltages and cycles available).
Card Indexing System
Electric motor driven infeed conveyor with a card pusher system for indexing the standard skin pack cards through the product loading station into the skin pack station (optional electronic speed control available for parts that may shift). Precision indexing film conveyors then move the card from the skin pack station to the trim press onto a package discharge.
Heating System
Advanced preheating system incorporates flat black far infrared type, which have been specifically designed to have a longer wave-length and corresponding heat - profile for better penetration of the heat into the film than conventional cal-rod types.Each heater is individually gradiated, or pre-zoned, so that the outer portions are hotter than
the center section (poor film drape is usually caused by an over concentration of heat in the center of the sheet).
Skin Packaging Station
Exclusive vacuum box design ensures precision skin packing of products by introducing the card (with product) up to the film in a parallel orientation. The film is automatically fed into the film clamp frame above to the vacuum box. This system prevents parts from shifting on the card while being skin-packed. The high volume vacuum system features individual vacuum and bleed control to ensure superior results.
Trim Station
Precision four post, high tonnage trim press (80 ton standard with higher tonnages available). Utilizes high efficiency, Zed exclusive method of locking the trim press platens and energizing a secondary.
All platens are solid steel, which span the entire trim area and are upwards of 5" thick, completely eliminating deflection, as experienced with fabricated platen structures. PACKAGE DISCHARGE: After die cutting, the individual cards are held in the web by tiny nicks in the die, which allow the entire card to index forward onto the outfeed package unloading area for case packing, etc.
Scrap Rewind
Unique switch valve system on the rewind mechanism provides a variable load while winding or holding between machine cycle advances. This insures proper card and film registry through the machine, without breaking the scrap web while bundling for easy disposal.
Controls System
Operator Interface Control panel, with Intel© Pentiums processor, provides for fast memory set-up and adjustment of operating parameters and sequences to the PLC through the color touch screen. This Windows based system provides a new dimension in functionality and ergonomics of the man/machine interface for improved machine efficiency and productivity.
This user-friendly system incorporates full graphic and animated process displays, prompting the operator through all the steps of operation and taking the guesswork out of setting up and running the machine. The touch screen is used to easily enter, access, adjust, monitor and store heater temperatures, cycle speeds, all process timers, machine sequencing, job/recipe storage, etc., adjustment of timers, heaters, production data, etc.
Technical & maintenance help is provided via self-diagnostics of fault conditions and corresponding corrective measures recommended. Additionally, PLC I/O cards can be monitored on the screen to assist and simplify component troubleshooting without having to open electrical panels or use of a meter.
