Feeders

DETERMINING THE TYPE OF FEEDER AND OPTIONS:

 

The following aspects are taken into consideration:

 

Type of Material

 

What type of finish will be present on the material during the production phase where the feeder will be used?  Is there a scratch-able surface?  Will the underside leave a mark if dragged along the top?

 

Weight of the Material

 

This helps determine not only the type of feeder itself, but also the type of support needed (sliding accumulator fingers, or rotating accumulator blades) if continuous application is desired.

 

Production Speed

 

We will offer you the type of machine that will coordinate with the production speed set for the rest of your processing line.

 

Production Area / Space Availability

 

Does  the direction of flow from input to output change?  Do you have the necessary space requirements to use actuator fingers rather that rotating blades?

 

Negative Air

Vacuum Cup

Rake Arm

Negative Air Feeder with  rotating accumulator blades and full size plenum for continuous feeding of panels one at a time from the top of a stack.

Stacks are conveyed into Feeder across elevator support beams.  The hydraulic elevator will then raise the stack to feed height.  The top panel is then lifted off of the stack by negative air pressure,  holding the panel against overhead belts which convey it to the Production Line.  The full size plenum and high volume air causes the panel to lift straight up against the belts and be fed without any sliding contact with the remaining panels of the stack.

 

After a panel has been removed from the stack, the elevator will then index the top of the remaining stack to feed height and the feed cycle starts again.

 

This process continues until approximately 10" of stack remains at which time accumulator blades will rotate under the remaining stack.  These blades will support the remaining stack, which allows the elevator to lower and accept another stack.  The accumulator blades index vertically to keep the top of the stack at feed height and allow panels to be fed during the entire elevator recycle.

 

The elevator will bring the new stack up under the accumulator blades.  When a new stack is in position, the accumulator blades will withdraw and place the remaining portion of the previous stack upon the new stack.

Also available with accumulator fingers for continuous operation with heavier product.

Vacuum Cup Feeder (non-continuous) for feeding of panels one at a time from the top of a stack.

Stacks are conveyed into Feeder across elevator support beams.  The hydraulic elevator will then raise the stack to feed height.  When a stack is at feed height, the vacuum cup will drop down and grip the top panel.  The cup will then raise and lift the back (or front) end of the panel, travel forward, and slide it into powered pinch rolls.  The pinch rolls pull the panel completely from the top of the stack and feed it into the production line.

 

After the panel has been removed from the stack, the elevator will then index the top of the remaining stack to feed height and the feed cycle starts again.

 

This process continues until the last panel of the stack has been fed out of the machine.

 

After the last panel has been fed from the stack, the feeding function stops, and the elevator will then lower rapidly to its lowest position to allow a new stack of panels to enter the Feeder.  There will be a pause in production during this elevator recycle.

 

NOTE:  CONTINUOUS MODELS ARE AVAILABLE

Rake Arm Feeder with  accumulator fingers (see example to the right) for continuous feeding of panels one at a time from the top of a stack.

Stacks are conveyed into Feeder across elevator support beams.  The hydraulic elevator will then raise the stack to feed height and the rake arms will hook the back edge of the panel and slide it into powered pinch wheels.  These pinch wheels will then pull the panel completely from the top of the stack and feed it to the production line.

 

After a panel has been removed from the stack, the elevator will then index the top of the remaining stack to feed height and the feed cycle starts again.

 

This process continues until approximately 10" of stack remains at which time accumulator fingers will slide under the remaining stack.  These fingers will support the remaining stack, which allows the elevator to lower and accept another stack.  the accumulator fingers index vertically to keep the top of the stack at feed height and allow product to be fed during the entire elevator recycle.

 

The elevator will bring the new stack up under the accumulator fingers.  When a new stack is in position, the accumulator fingers will withdraw and place the remaining portion of the previous stack upon the new stack.

 

NOTE: NON-CONTINUOUS AND ACCUMULATOR BLADES ARE AVAILABLE.
