Definitions

  • the present invention relates to a box or case forming machine, and more particularly relates to a case forming machine for proving the integrity of a corrugated blank before it is formed into a box or case.
  • Blanks are made from a single flat sheet of corrugated paper board or fiberboard which is scored to form the fold lines, cut or slotted to form the case flaps, then folded and glued to produce a blank.
  • An exemplary blank is depicted in Fig. 1.
  • a blank 10 is shown glued, folded and ready for forming in a case forming machine. It will be understood that the blank 10 typically comprises four case panels and four pairs of connected flap panels, each pair being adapted to engage with another pair as the box or case is formed. One half of the blank is identical to the other half in all salient respects so that only one half portion will be described.
  • a major case panel 12 is connected to a minor case panel 14 either by a fold line 16 or by a score line 24 and a glued flap 26. Extending from the major case panel 12 is a pair of major flap panels 20 and extending from the minor case panel 14 is a pair of minor flap panels 22. Each flap panel 20, 22 is separated from its adjacent flap panel 22, 20, respectively, by a flap relief slot 18.
  • Flaws in the blank 10 may appear in a variety of ways. They include inadequate or no glue on the glue joint at glued flap 26 resulting in a case that is incapable of maintaining a box shape upon forming, or too much glue resulting in failure to open since the blank will be glued shut. Other manufacturing flaws in the blank 10 may include improper placement of scores or slots which will inhibit successful forming of the box or case. Any of these flaws may result in the case forming machine failing to properly open the case, and/or causing the case forming machine to jam and stop. In an automated production line this can cause considerable down time and lost production.
  • the case forming machine includes a stacking magazine configured to receive and store a supply of blanks; a forming station for erecting the blanks and ejecting erected cases; a proving station intermediate the stacking magazine and the forming station for evaluating the condition of each blank before it is formed in the forming station; and a shuttle assembly for transporting each blank individually from the stacking magazine to the proving station and, for each blank that is evaluated to be in condition to form a case, transporting each blank to the forming station.
  • FIG. 1 is an isometric view of a prior art case blank.
  • FIG. 2 is an isometric view of a case forming machine according to the invention.
  • FIG. 3 is a top view of the vertical shuttle of the case forming machine of Fig. 2 in a first proving position.
  • FIG. 4 is a top view of the vertical shuttle of the case forming machine of Fig. 2 in a second proving position.
  • FIG. 5 is a top view of the vertical shuttle of the case forming machine of Fig. 2 in a third proving position.
  • FIG. 6 is a top view of the vertical shuttle of the case forming machine of Fig. 2 in a case forming position.
  • Fig. 2 depicts a case forming machine 30 according to the invention.
  • the case forming machine includes a stacking magazine 32 configured to receive a supply of blanks 10, a forming station 34 for erecting the blanks 10 into formed cases 10" and ejecting the formed cases, and a proving station 36 intermediate the stacking magazine 32 and the forming station 34 for evaluating the condition of a blank before it is formed in the forming station 34.
  • a supply of blanks 10 is vertically stacked on a conveyor assembly 38 that is configured to maintain a vertical orientation of the blanks and advance them toward a shuttle assembly 40, where the innermost blank 10' is positioned to be received by the shuttle assembly 40.
  • the shuttle assembly 40 includes a drive mechanism 50 that advances the shuttle assembly 40 to meet the innermost blank 10' from the stacking magazine 32.
  • a plurality of front vacuum cups 48, 49 secures the blank 10' to the shuttle assembly 40, where it then transports the blank 10' to the proving station 36.
  • the shuttle assembly 40 is shown disposed for vertical movement between the stacking magazine 32 and the proving station 36, it will be understood that the direction of movement of the shuttle assembly is not limited to vertical movement; however the stacking magazine 32 and the proving station 36 are disposed relative to each other will determine the direction of movement of the shuttle assembly 40.
  • a pre-break cylinder assembly 42 at the proving station 36 advances toward the shuttle assembly 40 opposite the blank 10'.
  • the pre-break cylinder assembly 42 includes a drive mechanism 54 that advances the pre-break cylinder assembly 42 to meet the blank 10'.
  • a plurality of rear vacuum cups 50 secures the blank 10' also to the pre-break cylinder assembly 42 so it is secured to both the shuttle assembly 40 and the pre-break cylinder assembly 42 in the proving station 36 as shown in Fig. 4.
  • a vacuum sensing switch 53 in the vacuum circuit will sense if the blank 10' is present and provide an indication on a monitor 80 (see Fig. 1). The vacuum sensing will also provide an indication at subsequent steps in the case forming to indicate whether the blank 10' is qualified to proceed further in the process.
  • the drive mechanism 50 causes the shuttle assembly 40 to reverse direction 62 away from the pre-break cylinder assembly 42, and simultaneously the drive mechanism 54 causes the pre-break cylinder assembly 42 to reverse direction 64 away from the shuttle assembly 40.
  • the front and rear vacuum cups 48, 49, 52 continue to hold the blank 10', whereby the pre-break cylinder assembly 42 urges the panel to which it is secured to move away from the panel to which the shuttle assembly 40 is secured while the pre-break cylinder assembly 42 and the shuttle assembly 40 move away from each other.
  • an erector arm 60 rotates out of the shuttle assembly 40 against the blank 10'.
  • the resulting motion tends to cause the blank 10' to open if it is able and to not fold back onto itself.
  • the erector arm 60 and the pre-break cylinder assembly 42 and the shuttle assembly 40 then stop their motion to hold the blank in a pre-break position (See Fig. 5), preferably a parallelogram.
  • the vacuum switch detects the integrity of the blank 10' to form a case. For example, if there is too little glue causing the blank 10' to disassemble, the vacuum system will indicate such on the monitor 80. For example, the vacuum system may determine that the vacuum force needed to hold the blank 10' is below a minimum threshold, indicating that the blanklO' lacks the requisite integrity. The vacuum cups 48, 49, 52 then release, enabling the flawed blank 10' to be ejected from the case forming machine 30. Ejection can be automated or manual. For example, a flaw determination may stop the machine 30, notify the user via the display 80, and await resetting after the user manually ejects the flawed blank 10' from the machine.
  • the vacuum system will indicate such on the monitor 80. For example, the vacuum system may determine that the vacuum force needed break open the blank 10' is above a maximum threshold, indicating that the blanklO' lacks the requisite integrity.
  • the vacuum cups 48, 49, 52 may release, enabling the flawed blank 10' to be ejected from the case forming machine 30.
  • Other sensors may be employed to determine the integrity of the blank 10', such as optical sensors, imagers and the like.
  • the vacuum cups 52 on the pre-break cylinder assembly 42 release, and the pre-break cylinder assembly 42 continues to the move away from the blank 10' in the direction 64. Meanwhile the shuttle assembly 40 transports the partially erected blank 10' to the forming station 34, where the case may be erected in a conventional manner. The erector arm 60 continues rotating out of the shuttle assembly 40 to its final position in the forming station 34 as shown at Figs. 2 and 6, w here the blank 10" is now fully open.
  • the forming station 34 At least two pairs of major and minor flaps panels 20, 22 are folded, whereupon the vacuum cups 48, 49 and the erector arm 60 release the blank 10" from the shuttle assembly 40.
  • the blank 10" (partially formed case) is then urged toward a case scaler 44 which glues and/or tapes at least two pairs of major and minor flaps panels 20, 22 to form the case, which is then ejected from the case forming machine 30 at 46.
