6.4.10.3 Adjustments of Air Pressure Values with the Compressed Air Testing Device

Fig. 6.4 - 15 Flow chart determining air pressure values

Please Note:

Air pressure values, displayed on the screen of the station computer, under option "Measure air

pressure" of the "Single functions", or in the SITEST program, do not correspond to the air

pressure values actually set at the nozzles.

They solely serve to check that the forced air valve is functioning correctly.

Therefore, the air pressure may not be adjusted with the values displayed on the screen.

Instead, use only the values determined with the compressed air testing device. 6

Please Note:

The adjustment for the reject circuit is not necessary on the HF/Siplace X machine.

Please Note:

Both forced air circuits are controlled by a single valve and therefore are mutually dependent.

Using two different restrictor valves, it is however possible, to adjust differing pressure values for

each circuit. 6

➠ Repeat these adjustments several times, as the pick - up / placement circuit are mutually

dependent.

Please Note:

Make sure that the test sensor tube is attached air - tight on the nozzle. 6

6.4.11 Other Mechanical Adjustments on the Star

➠ Insert the blast air transition tubes so that they will protrude 0.7 mm from the surface of the

circular arc guide.

Please Note:

The blast air tubes at the valve plungers should be at a distance of 0.2 mm from the encoder

of the DP-axis. 6

6.5 Nozzle changer

The Siplace HF/Siplace X is supplied with 6 segment or 12 segment collect&place heads. As an

option, a nozzle changer can be installed for each collect&place head. This enables the nozzle

configuration to be changed quickly, thus allowing the Collect&Place head to be quickly adapted

to the needs of the placement process.

6.5.1 Nozzle changer for 12 segment C&P head

The nozzle changer consists of at least one, and up to ten magazines, each with twelve nozzle

garages. The magazines are seated on a common support and each magazine is centered using

two parallel pins and fixed in place with a spring hook.
