2.5.7 Lift Cylinder Flow Control Adjustments (SIPLACE JTF-S)

Lift Cylinder Flow Control Adjustments (SIPLACE JTF-S)

The speed settings for the lift cylinder must sometime be changed in relation to the weight of the stack

of trays. To maximize the throughput on the feeder, increase each ﬂ ow control setting until you ﬁ nd the

fastest speed at which the entire stack of trays cycles in a smooth motion without upsetting the compo-

nents in the trays.

► Before performing this adjustment, check that the input pressure to the feeder is 60 psi.

► Remove the lift cylinder cover (see figure "Removing Front Cover").

► Before making this adjustment, you must ﬁ rst unlock the ﬂ ow control by turning the locking knob

counter clockwise.

► To increase the airflow and increase the speed of the tray stack lift, turn the flow control adjustment

knob in a counter clockwise direction.

► To decrease the airﬂow and decrease the speed of the tray stack lift, turn the flow control adjustment

knob in a clockwise direction.

► When you are satis ﬁ ed with the lift cylinder adjustments, lock the ﬂ ow controls and assemble the lift

cylinder cover.

2.6.1 Main Air Regulator Adjustment

Main Air Regulator Adjustment

► (1) Check the air pressure reaching the feeder. This should be 60 psi (4.1 bars).

Newer feeders which are prepared to work with the air pressure gauge (air pressure maintenance kit -

P/N 9043931). This kit allows you to check the pressure actually reaching the feeder. Connect the pres-

sure gauge to the micro coupler (see figure "Air pressure gauge from maintenance kit") and check that

the output pressure is 60 psi (4.1 bars). If adjustment is required, remove the front cover (step 2), then

perform steps 7, 8, 9 and 11. On older feeders it is necessary to disconnect air pressure to the feeder

and follow steps 2 thru 6. If adjustment is required follow steps 7 through 11.

► (2) Remove the front cover by loosening the two M4 screws (see figure "Remove Front Cover" for

screw locations).

► (3) After removing the front cover, locate the main air pressure regulator (see figure" Location of

Pressure Regulator").

► (4) Disconnect the output line tubing line H2. See figure "Location of Pressure Regulator".

► (5) Connect the air pressure gauge to the output line (see figure "Checking The Main Air Pressure").

► (6) Reconnect the air pressure to the feeder.

⇨ The air pressure coming from the pressure regulator should be 60 psi (4.1 bars).

► (7) If the output air pressure must be adjusted, unlock the regulator adjustment screw by loosening

the locking knob (see figure "Location of Pressure Regulator").

► (8) To increase the output air pressure, turn the adjustment screw counter clock wise (see figure "Lo-

cation of Pressure Regulator"). To decrease the output air pressure, turn the adjustment screw

clockwise.

► (9) Lock the regulator adjustment knob once the desired air pressure is set.

► (10) Disconnect the air supply to the feeder. Remove the gauge and reconnect the output line tubing.

► (11) Reconnect the air supply to the feeder. Check for air leaks and assemble the front.
