Two-station die-cutting machine GW S 106 YQ with hot foil stamping and stripping

Feeder

• High-quality feeder (Taiwan) with 4 suckers for lifting paper and 4 suckers for forwarding paper to ensure fast and stable sheet feeding. The height and angle of the suckers are easily adjustable so that the sheets are delivered straight.
• MABEG feeder (optional) for precise results in loading and feeding into the machine.
• Mechanical double-sheet control, a late-sheet detection device and an adjustable air blower ensure reliable and precise sheet transport.
• Becker compressor.
• Motorised lateral pile shift for precise feeding.
• A perfectly aligned sheet pile can be built on pallets that move on rails and allow pre-piling. This creates an important precondition for trouble-free production, and the operator can move the prepared pile precisely and comfortably into the feeder (max. pile height 1600 mm).
• The single-position engagement of the pneumatically controlled mechanical clutch ensures that after every restart the first sheet is always precisely delivered to the front lays for easy, quick and material-saving make-ready.
• The side lays can be switched between pull and push mode on both sides of the machine simply by turning a pin, without mounting or dismounting any parts. This ensures flexibility in processing a wide range of materials, regardless of whether the register marks are on the left or right side of the sheet.
• The side and front lays are equipped with precise optical sensors that detect black colour and plastic sheets. Sensor sensitivity is adjustable.
• Optical sensors with an automatic stop system on the feed table optimise the monitoring system for comprehensive quality control across the entire sheet width and in the event of a sheet jam.
• The control panel on the feeder, used for easier control of the feeding process, has an LED display.
• Separate drive control for the main pile and auxiliary pile.
• PLC and electronic cam for timing control.
• A foreign object protection device can prevent machine damage.
• Japan Nitta feeder conveyor belt with adjustable speed.
• Ultrasonic (SUPERSONIC) double-sheet detection (optional).
• Static eliminator on feeder/delivery (optional).

Die-cutting unit

• A pneumatic locking system makes it easier to lock and release the cutting die and cutting plate.
• Pneumatic lifting cutting plate for easier insertion and removal.
• A centring system on the cutting chase with diagonal fine adjustment ensures precise registration, allowing quick job changes.
• Precise positioning of the cutting die is controlled by a precise optical sensor with an automatic check and locking device.
• Cutting die turning device.
• A Siemens main motor controlled by a Schneider inverter ensures smooth and trouble-free operation.
• Fine adjustment of cutting force (pressure accuracy max. 0.01 mm, max. cutting force up to 300 tonnes) is provided by a servo motor with worm gear, controlled via a 15-inch touch screen.
• The crankshaft is made of chrome steel (40Cr).
• The machine frame and ram are made of ductile cast iron (HT300).
• 7 sets of gripper bars made of light and durable aluminium alloy with an ultra-hard anodised surface ensure precise and consistent paper registration.
• The high-quality gripper bar from Japan offers a long service life and needs no compensation spacer to ensure precise paper registration.
• Cutting plates of various thicknesses (1 pc – 1 mm, 1 pc – 3 mm, 1 pc – 4 mm) allow easy job changes.
• A high-quality pre-stretched Renold (UK) chain ensures stability and accuracy even for long-run jobs.
• The high-pressure gripper bar registration system ensures precise positioning.
• An overload protection device with torque limiter ensures a high level of safety for operator and machine.
• Automatic lubrication and cooling system for the main drive and automatic main chain lubrication.

Foil unit – hot foil stamping

• Independently controlled programmable foil pull rollers (3 sets longitudinal and 2 sets transverse) driven by YASKAWA servo motors.
• Longitudinal full-format foil loading system for stamping in 2 directions simultaneously greatly helps save foil and shortens foil change time.
• 20 separately controlled heating zones using an intubation heating system with a temperature tolerance of ±1 °C.
• 1 set of ductile iron honeycomb plate and locking device for die-cutting.
• Dwell device for stamping large areas.
• Two-way separating blower.
• Brush system for removing foil waste from the side of the machine, where it can be collected and disposed of.
• Optical sensors for detecting broken foil.
• The optional WFR-280 foil rewinder for disposing of used foil winds it onto six independent reels in a dedicated free-standing module.
• The optional COMPACT foil rewinder for disposing of used foil winds it onto 4 reels located at the bottom of the machine.
• Hologram applicator for inserting hologram tape (optional).
• A time heater preheats the machine and prepares it for production before the start of the shift (optional).

Delivery

• An adjustable AC-motor-driven brake brush helps take paper from the grippers and stack it at higher speed with perfect pile alignment.
• The delivery pile height is max. 1350 mm.
• A photoelectric device monitors and prevents excessive rising or lowering of the paper pile.
• Sheets in the pile can be counted by an optical sensor (standard), and this unit can be integrated with a tape inserter for placing paper markers in the pile (optional), making it easier to remove unprinted sheets and pack.
• The entire machine can be set up via a 10.4-inch touch monitor at the rear of the machine.
• An auxiliary conveyor grid makes it easier to configure the machine as a non-stop delivery.

Electrical components

• Electronic detectors, microswitches and photoelectric sensors throughout the machine are controlled by a programmable logic controller (PLC).
• Electronic switching cam for encoder switching.
• All main operations can be controlled via 15- and 10.4-inch touch monitors.
• PILZ safety relays (standard) ensure a high safety standard for the whole machine.
• The internal locking switch meets all CE requirements.
• Electrical components including Moeller, Omron, Schneider relays, AC contactors and air circuit breakers ensure stability for long-run jobs.
• Error display and automatic fault diagnostics.

Other features

• Operating platform with heating controller.
• A tool set and operating manual are included.
