2.6.5 Checking Pawl Movement (SIPLACE JTF-S)

Checking Pawl Movement (SIPLACE JTF-S)

Both the short pawls and long pawls are located in the tower area of the feeder, near the level of the

conveyor (see figure "Bottom Plate and Mounting Screws"). If the pawls do not move freely, the motion

of the trays may become unreliable.

► To test a short pawl, move each one with your ﬁ nger. Each short pawl should move easily.

► To test a long pawl, push the long pawl to one side.

► Check to see that the long pawl can move freely in the up-and-down direction.

► Push the long pawl to the other side, and test again.

If the pawls are sticking, do not lubricate them! The lubrication will cause the pawls to stick, and increase

the problem. Instead, disassemble the mechanism and clean the parts using alcohol.

2.6.6 Lift Cylinder Shock Absorber Adjustment SIPLACE JTF-S

Lift Cylinder Shock Absorber Adjustment SIPLACE JTF-S

The lift cylinder shock absorbers are designed to slow the rod less cylinder body at the end of its stroke

(see figure "Slip clutch elevator"). The shock absorber is not designed to be used as a stop. The rod less

cylinder body stop point is determined by the pawl lift rod stopping at its end of travel.

The following procedure outlines how to verify the shock absorbers are correctly adjusted, and how to

adjust if necessary.

► Remove the cover on the lift mechanism (see figure "Alignment Pins").

► Disconnect power to the feeder (leave the air pressure connected).

► Manually ﬁ re the lift cylinder down and measure the gap between the lift cylinder body and the shock

absorber (see figure "Incorrect-Elevator Bar is Not Level" to locate the lift cylinder manual activation

solenoid valves).

⇨ The gap should be approx. 3/32." (see figure Incorrect – Elevator Bars at same Level"). The body of

the shock absorber must not contact the body of the lift cylinder.

► Manually ﬁ re the lift cylinder up and observe the gap between the lift cylinder body and the shock

absorber on the other end of the stroke. The gap should be approx. 3/32."

► If adjustment is required, loosen the lock nut on the shock absorber and turn the shock absorber until

the proper gap is reached.

► Tighten the lock nut.

► Manually ﬁ re the lift cylinder in the opposite direction then back again to verify proper adjustment.

► Attach the lift mechanism cover.
