The round belt system is capable of operation from to 1kg The high throughput conveyor system transports the board from the upline machine using belts from the upline auxiliary conveyor, into the print station of the machine, where the board is positioned, clamped and printed After printing the board is transferred to the downline machine using belts from the downline auxiliary conveyor There are four modes of operation, selectable on the M27, as follows: • Single Stage Normal Mode • Single Stage Fast Mode • Three Stage Normal Mode • Three Stage Fast Mode NOTE Large apertures in the product board can cause the sensors to activate/ deactivate In the event of false triggering, select Normal Mode If dual speed rail motors are fitted to the print station, an additional alternative motor speed is available to de-accelerate the product prior to reaching the camera board stop Single Stage Normal Mode In single stage normal mode the auxiliary rails and the print station rail are configured as one rail The rail system transports the board from the upline machine, into the machine, where the board is positioned, clamped and printed After printing, the board is transferred to the downline machine A signal to the upline machine, to dispense another board, is sent when the leading edge of the board switches the ‘board present’ sensor on the downline machine If the downline machine has a board at the sensor, the conveyor board stop activates to prevent the board leaving the print station In single stage normal mode, only one board can be in the machine at any one time Single Stage Fast In single stage fast mode the signal to the upline machine, to dispense another board, is sent when the trailing edge of the printed board passes the board at Mode right sensor on the print station In the event of the downline machine being busy, the board is stopped at the end of the print station In single stage fast mode, two boards can be in the machine at the same time (one entering the machine on the upline auxiliary conveyor as the printed board is exiting on the downline auxiliary conveyor) 20.2 Technical Reference Manual Chapter Issue Nov 11 HIGH THROUGHPUT CONVEYOR (HTC) MODULE OVERVIEW - HTC RAIL SYSTEM NOTE If the downline transfer time is greater than the machine cycle time (displayed on the machine MMI), single stage normal mode must be selected to prevent two boards on the downline conveyor at the same time Three Stage Normal Mode In three stage normal mode the upline auxiliary conveyor transports Board to the print station conveyor where the board is processed With Board in print position, Board is dispensed from the upline machine When Board arrives at the sensor, at the end of the upline auxiliary conveyor, the transport belts stop Board Direction from Left to Right Upline Conveyor Board Stop KEYENCE PZ-42L KEYENCE PZ-42L KEYENCE PZ-42L Board KEYENCE PZ-42L KEYENCE PZ-42L Board Print StationConveyor Downline Conveyor Board Stop Board Stop Plan View of Board Positioning (Three Stage Mode) After the print cycle, the Board is transported to the downline auxiliary conveyor When the leading edge of the board activates the sensor, at the end of the downline auxiliary conveyor, a signal is sent allowing Board to enter the print station and Board to enter on the upline auxiliary conveyor Board Direction from Left to Right Upline Conveyor Board Stop KEYENCE PZ-42L KEYENCE PZ-42L Board KEYENCE PZ-42L KEYENCE PZ-42L Board KEYENCE PZ-42L KEYENCE PZ-42L Board Print StationConveyor Downline Conveyor Board Stop Board Stop Plan View of Board Positioning (Three Stage Mode) Providing the downline machine is ready, the first board can leave the downline auxiliary conveyor and the cycle be repeated If the downline machine is busy, the second board is printed and transported to the end of the print station conveyor where it is held by the conveyor board stop Chapter Issue Nov 11 Technical Reference Manual 20.3 HIGH THROUGHPUT CONVEYOR (HTC) MODULE OVERVIEW -

HTC RAIL SYSTEM Three Stage Fast Mode In three stage fast mode, the operation is the same as three stage normal mode with one exception The second board is transported on to the print station when the trailing edge of the first board passes the board at right opto situated at the end of the print station conveyor Board Clamping The transport rails can be fitted with one of the following board clamping arrangements: • Over the Top Snuggers (OTS) • Board Snugger Assembly • 250, 380 and 500mm Board Clamps • Foil-less Clamps OTS is a system that clamps the board until the snugger part of the mechanism holds the board; at this time, the clamps release (see the OTS section of the Transport Rails chapter for details.) Board snuggers are an alternative to the standard board clamps and are utilized when there is a requirement to print close to the board edge Foil-less clamps are utilized for thin pliable boards where there is a requirement to print close to the board edge The foil-less clamps are assisted with the use of a vacuum box beneath the product board Chapter Issue Nov 11 Technical Reference Manual 20.5

measured using a tachometer on the input or output pulley, check the speed to be approximately 500mm/sec (30m/min) Board Transport Belt Speed (Print Station Rail) WARNING BOARD CLAMPS EXTREME CARE MUST BE EXERCISED WHEN WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID INJURY THE FOILS ON THE FRONT AND REAR BOARD CLAMPS ARE VERY SHARP The front and rear board transport belts, of the print station rail, are driven independently by two variable speed motors Inevitably one motor drives faster than the other motor It is necessary to calibrate these motors so that they drive at the same speed in either direction Therefore, the faster motor must be calibrated to match the slower motors speed Each belt motor speed is controlled by a separate speed controller module situated between the rails on the right hand side of the machine The belt speed is measured using a tachometer on the underside of the input or output pulley and adjusted using the potentiometer on the speed controller
