Screen Shuttle Sequence - Image at the Rear

Automatic Load - Rear Screen Shuttle

This operation may be the first or a follow-on operation after a front load print

sequence. Hence, a batch of front loaded boards may be printed first and this

batch printed second or vice versa.

1. The first board in the batch is fed to the inroad conveyor sensor where it

stops.

2. The machine interrogated either the bar code reader (BCR) or the board

present sensor to check that the board has arrived ready for loading (for the

BCR, the correct product file is loaded).

3. If the presence of a board is detected by the product sensor (option) then the

board is deemed of the type for the product file - and set in accordance with

this configuration, the product file is loaded.(See Note below)

4. As the board details have been confirmed, the machine starts the shuttle

action of the screen.

5. The chase clamps release the screen.

6. The front screen shuttle actuators grip the screen at the side, the rear actuators

remain engaged in the slots at the rear of the screen.

7. The screen shuttle actuators move the screen rearward in the chase by the

amount given in the product file.

POSITIONING

POSITIONING All sensors are positioned on the input frame and take into account any features

that may prevent product from being correctly loaded. As the parameters for

the products differ, board lengths and widths may vary, with the exception of the

screen home position, fixed positions are not quoted. All other positions for the

system are shown in the various chapters of the Infinity Technical Reference

Manual.

Screen Home

Position

Refer to the Infinity Technical Reference Manual for details on setting this

parameter.

Distance to Image

Reference Position

This parameter is used to set the position of the product images.

1. Tape the product image to the correct stencil such that the images line up, see

figure overleaf.

2. Measure the distance to the front edge of the product with respect to the

leading edge on the rear of the stencil or skis.

3. Input the value into each product file. See section: Adjustments and Settings

- Distance to Image.

4. Remove the products from the rear of the stencil, fit the stencil into the

machine and test (the images should align when the rising table lifts the

product to the print position). Adjust the parameter in the product file if

necessary.
