The Model SP-M160, consisting of Mandrel Assembly, Turret System, and Carriage Conveyor, is adjustable to run four carton gable-top sizes at the max rate speed of 16,000 packs/hr depending on the product to be filled;
10 oz. (296 milliliters)
8 oz. (237 milliliters)
6 oz. (178 milliliters)
4 oz. (119 milliliters)
The basic elements are:
*Magazine: Each magazine can hold 500 carton blanks that are supplied by gravity flow to the feeder loader.
*Feeder-Loader: Each feeder-loader, equipped with vacuum heads, removes the carton blanks from the magazine, then opens, squares, and loads them onto a mandrel.
*Mandrel Assembly: Each mandrel assembly is water cooled and moves the cartons through the bottom sealing operations.
*Bottom Heater: At the bottom heater, heated air softens the polyethylene coating on the bottom flaps of the carton.
*Bottom Breaker: At the bottom breaker, two triangular wings crease the bottom flaps of the carton.
*Bottom Sealer Assembly: on the bottom sealer assembly, the folded bottom flaps are pressed by an pneumatically operated pad and simultaneously cooled into final shape. Convex stake points on the pad emboss punch marks across the seams on the bottom.
*Unloader: The final stop of the mandrel positions the cartons at pockets of a turret system, where vacuum heads on the sides of the unloader causes them to adhere through suction.
*Turret: On the turret, two cartons are turned 90 degrees clockwise, then pushed down into the holders of the carriage conveyor.
*Carriage Conveyor: The carriage conveyor moves the cartons through the filling and top sealing processes. The cartons are conveyed by two pitches per cycle.
*Primary Top Breaker: The first station on the conveyor line is the primary top breaker. The top flaps of two cartons are simultaneously creased by triangular wings.
*Bottom-Up Filler Assembly: Next, the two cartons are brought into position under the filler nozzles of the bottom-up filler assembly. A carton lifter raises them until the nozzle tips are very close to the bottom of the cartons. This minimizes foam and eliminates the need for a defoamer. Each filler assembly interior is sterilized by steam (212 Deg. F max, or 100 Deg. C) at the beginning of each work shift.
*Second Top Breaker: The filled cartons are then moved forward to the second top breaker where the tops are again creased by wings along the score lines.
*Top Heater: The polyethylene coating on the carton tops is softened by heated air at the top heater.
*Top Sealer Assembly: Two cartons arrive at the top sealer assembly. Pneumatically driven pressure jaws clamp shut on the preheated top-sealing flaps, simultaneously pressing them together and cooling them into a seal.
*Dater Assembly: The top fins of the completed cartons are stamped with the date by the pneumatically operated and heated dater.
The formed, filled, and sealed cartons are carried from the discharge end of the machine.
