Mode of operation:
Three-quarter automatic operation
Print table reciprocates in/out of the print station
After gaskets are printed two rows of integrated robot arms with vacuum suction cups automatically remove gaskets from print table onto adjustable speed automatic conveyor belt with rear delivery into dryer or next conveyorized process

Features:
• Four-post Air Locking: equipped with unique four-post air locking function (activated while printing), assures printing stroke and table top is parallel for high precision printing accuracy.
• Magnetic Table: suitable for firmly holding different sizes and patterns of gasket on the table for printing.
• Uniform Ink Layer: squeegee / flood coater is driven by guide rail cylinder for high accuracy of linear motion and smooth, equalized printing pressure onto substrate. This system assures even and consistent printing of ink layer.
• Servo Motor Direct Drive: solid printing torque for stable low to high speed control. Servo motor attains stable, smooth, precise, vibration free low to high speed motion.
• Equalized Control: squeegee / flood coater digital equalizer system control. Print / flood air pressure force parameters can be preset with output range 6.6 – 137 lb (3~ 62 kgf) on HMI. Parameter can be saved and recalled for repeat jobs and/or common applications.

A. DIGITAL STORAGE OF SETTINGS
Up to 100 recipes of digital settings containing all important print parameters can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Includes, but is not limited to, off-contact, off-contact delay, all peel-off functions, all print modes, preset number of prints, squeegee and flood coater stroke length, pressure range, and speed. This time-saving feature offers repeatability and efficiency while significantly reducing job set-ups and changeovers. HMI color touch panel with 7” screen provides consistent control over print quality.

B. FRAME (CHASSIS)
New high rigidity frame designed for highest torsional strength keeps machine vibration free at all speeds and suitable for CCD Surveillance System.

C. SCREEN UP/DOWN
German SEW-Eurodrive motor powers four-post head lift on linear bearings and guide rails. Includes synchronized transmission shaft, double chain, encoders and photo sensors to control screen up / down position.

D. PRINT OFFSET DISTANCE
Touch-screen digital settings can be set for light squeegee pressure at the beginning of the print stroke and then once past the edge of substrate regular full pressure can be applied according to the input setting distance. This feature prevents squeegee rubber from ripping screen against direct contact of sharp edge or corner of rigid substrate. Allows longer life of mesh and squeegee rubber. Digital setting of print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.

E. OFF-CONTACT
Touch screen digital setting of off-contact is an important print parameter that can be stored, saved, and recalled for repeat jobs and/or common applications. Reduces setup and changeover.

F. SERVO DRIVEN SQUEEGEE AND FLOOD STROKE
Squeegee and flood coater travel is servo-driven for stable low to high speed control, with linear guide rails and cog toothed belt for smooth, precise, vibration free printing, ensuring absolutely even and uniform ink deposit. Touch screen digital setting of this print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.

G. SERVO DRIVEN PEEL-OFF
Digitally controlled servo peel-off distance of start/end point can be set relative to image size, with variable speed and height control. Touch screen setting of this print parameter can be stored, saved, and recalled for repeat jobs and/or common applications. Reduces setup and changeovers.

H. PRINT TABLE MOVEMENT CONTROL
Print table motion cycle driven by top-class servo motor, using swivel arm system guided by linear rail for consistent repeatability.

I. PNEUMATIC FRAME LOCKING
System with check valves / airlock and four-sided frame holding assembly ensures rigidity and high stability.

J. DIGITAL PRESSURE EQUALIZATION
Print and flood coater pressure is digitally settable with fully automatic pressure equalization system and auto-leveling function controlled by touch screen for precise balance and consistency of printed ink film layer. Digital setting of print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Improves print quality and reduces setup and changeovers.

K. NO-PEEL FLOOD COATER FUNCTION
No-peel flood coater function has digital settings that can be saved, recalled, and adjusted from the touch-screen.

L. HIGH-PARK OF SQUEEGEE AND FLOOD
Squeegee & flood high-park allows screen loading and unloading without removing squeegee holder and flood coater. This facilitates rapid setups and change-overs.

M. PRINT SELECTION MODE
Choice of flooding before the print stroke, flooding after the print stroke, or higher cycle speed-flood while screen lifts to full "up" position, and after specified number of print strokes (from 1 - 5 times in one cycle). Digital setting of print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.

N. SET NUMBER OF PRINT CYCLES
Digital setting for the number of print cycles necessary for printing job and the machine will stop running automatically upon completion of set amount. Print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.

O. FRAME HOLDER PIN REGISTER
Screen frame holder is equipped with rear registration pin system for fast and repeatable frame position centering to reduce setup time.

P. LINEAR GUIDE RAIL CYLINDER FOR SQUEEGEE AND FLOOD COATER
Linear guide rail cylinder for smooth vibration-free squeegee and flood coater up and down movement. Includes precise micro adjustment control with numbered fine-tuning depth, skew-angle (snowplow feature), and numbered swivel angle of squeegee and flood coater. Allows the highest degree of repeatability, reliability, accuracy, and extremely precise even pressure of the squeegee and flood coater. Overall print quality is optimized.

Q. FOUR-POST LOCKING
Unique four-post locking system ensures that no lifting of print assembly or corner post can occur, while keeping perfectly parallel to the print table at all times during the printing sequence. This benefit allows controlled, consistent even ink deposit, while preventing mesh elongation. Accurate off-contact distance is effectively kept across the entire the surface of the mesh.

R. SAFETY LOCK FOR SCREEN CLEANING
Screen cleaning safety switch located at the rear of the machine completely disables any start function to protect operator when cleaning the screen. Operator can completely lock out the machine to prevent any chance of machine activation.

S. SQUEEGEE AND FLOOD COATER ADJUSTMENTS
Squeegee and flood coater depth, inclination, and bias angle are finely adjustable using a sophisticated micrometer to minimize chatter and vibration from irregular print surface heights and traces.

T. SCREEN LEVELING
Four corner screen leveling of frame holder allows fine adjustment to compensate for mesh tension or uneven frames, and to always position mesh parallel with the table surface.

U. LOW PRESSURE DETECTION STOPS MACHINE
Filter regulator lubricator (FRL) triad assembly is equipped with an automatic pressure detection switch that stops the machine when low air pressure is detected.

V. FRL OIL FREE FOR CLEAN ROOM ENVIRONMENT
The control system for compressed air supply is an oil free FRL unit to prevent oil mist pollution, particularly applicable in clean room environments.
