Definitions

  • the present invention relates to a mold-design to manufacture expansible-side paperboard bags using a fully automatic gluing/folding machine.
  • the mold design used to make the bag is a mold with a four-section structure (FIG. 1. 1 ); the first section is the upper lap and its opposite side is called the upper face; the second section is the side lap and its opposite side is called the left-hand expansible side; the third section is the lower lap and its opposite side is called the lower face; and the fourth section is the side lap and its opposite side is called the right-hand expandable side.
  • the latter section includes a gluing stub, and the side laps are creased down the middle so that they can be easily folded.
  • the bags are also creased along the side laps and between the upper and lower laps.
  • the edges of the upper and lower laps are cut on an angle, and the edges of the side laps are cut at a right angle, with a small diagonal cut where they meet the edge of the upper or lower laps, and the laps are creased along with their entire length, the creasing of all laps allowing for suitable fold when gluing the bags.
  • the mold-design section is straight, with only four holes used to insert two pieces of string to be used as handles.
  • the product immediately enters the machine on conveyer belts (FIG. 2. 2 ) that guide the bag mold/design to the folding guides (FIG. 2. 3 ). These guides fold the right-hand expansible side along its entire length, using the crease at the center of the expansible side mold-design.
  • a strategically placed hook pulls the gluing stub and when the hook passes the mold-design, a magnet returns it to its original position.
  • a smaller guide is used to ensure consisting folding.
  • a folding guide folds the entire length of the left-hand expansible side.
  • the mold-design passes through a compression band that keeps the folds compressed, and keeping the right and left-hand expansible sides and the right-hand lap completely flat (FIG. 3. 1 ).
  • An electric eye determines the part of the side gluing stub on which glue will be applied, and then shoots the glue automatically, leaving a hot layer on the bag side or gluing stub.
  • the upper half of the bag and the upper lap are folded by a bouncing belt (with an up and down movement) and are then joined to their counterparts, permitting adhesion to the gluing stub. Due to the type of flue used, this bond dries almost immediately.
  • the bag is immediately removed on a special conveyer belt that raises the upper lap of the bottom with a hook that keeps the lap folded backwards.
  • a special conveyer belt that raises the upper lap of the bottom with a hook that keeps the lap folded backwards.
  • the upper lap of the base is folded, it pulls the left and right-hand expansible sides leaving two triangles on each side where the bottom will be, the side laps and the upper and lower laps.
  • An electric eye then enters, detects the product, sees how the upper lap of the bottom is kept raised, and with an insertion attachment inserts a square or rectangular bottom (FIG. 4. 1 ), depending on the shape of the finished bag, which should be equal or similar to the surface area of the bag's bottom, for added strength. This additional bottom section is optional.
  • the product enters a second automatic feeder, which sends the bag on to special belts on which the bottom side laps are folded. These sidelaps fall on or cover the triangles formed by folding the expansible sides so that the previously placed bottom section is placed correctly.
  • the product then passes through a speed differential and is rotated 90 degrees from right to left on the conveyer belts, so that it continues rotating in the same direction as the belt, but in a different position.
  • the last part of the gluing process can be completed without rotating 90 degrees, without which bag manufacture would not be possible.
  • a last electric eye detects the bag and shoots hot glue along the width of the bottom section.
  • the bag then enters a drying tunnel where the drying process is completed.
  • the first part of the machine is designed to produce pre-folded linearly glued boxes, boxes with internal compartments, pillow boxes, double-wall boxes and retail products with special finishes.
  • This machine has a circulation tunnel through which the product passes in forty seconds. It also has an attachment that handles final folding of the product, giving it great versatility for processing custom manufactured products.
  • the second part of the machine is the gluing-folding section, which has a circuit with special features in the rear section for final product assembly.
  • Re-directing unit which rotates the product 90 degrees for finishing
