A high speed, straight line, automatic system to glue
absorbent soaker pads into styrene foam packaging trays.
The PAD-O-MATIC 360W was designed to operate in line
with the thermoforming process in the tray production plant. The machine is mounted on
castors to allow easy movement of the padding machine to the thermoforming line running
the tray size to be padded. The trays are taken from the trim press packaging table and
fed into the PAD-O-MATIC 360W denester or placed on the optional Tray Loading Conveyor.
The PAD-O-MATIC 360W consists of a denester station to denest vertical stacks of foam
packaging trays and feed them onto a single row flight conveyor. The denesting system does
not require stacking lugs on the trays or any modification to the thermoformer tooling,
other than removing any embossing that is on the bottom of the tray in the contact area of
the suction cups.
The flight conveyor transports the trays to the pad
application unit. At the pad application unit, rolls of padding material are unwound from
dual unwind spindles, which are equipped with constant tension brakes. The pads are cut to
a predetermined length, which is set on the touch screen operator interface, then hot melt
adhesive is applied to the tray by adhesive guns, and the pad is positioned in the tray on
the flight conveyor.
The padded tray continues on the flight conveyor to
the stacking conveyor. At the stacking conveyor, the padded trays are rotated to vertical
position, counted, and horizontally stacked on the packaging table.
The packaging table is equipped with a pneumatic bag
opening device to open wicketed polyethylene bags, fast pak bags, or an unwind can be
provided to use rolled, perforated bags. There are guides to allow easy insertion of the
stacked, counted, padded trays into the poly bags. The bag holder and opening unit may be
mounted to provide straight through (top of tray to bottom of bag) or reverse (top of tray
to top of bag) packaging.
The PAD-O-MATIC 360W has an on-board vacuum pump and
an automatic pressure lube system with alarm to lubricate all chains and gears. All
electrical meets NEMA 12, JIC, and CE standards.
The PAD-O-MATIC 360W features improved size
changeover with a single point handwheel adjustment for flight conveyor width, flight
conveyor rail height, and stacking conveyor width.
