Definitions

  • This invention relates to the art of folded boxes and more particularly to belt type folding equipment for automatic folding of corrugated box blanks of the type that comprise four panels in side by side relation that have been pre-scored to facilitate folding of the two outer panels into substantially edge to edge juxtaposition.
  • the outer panels will take a longer time to reach the outlet of the folding equipment than the other panels moved by the horizontal conveyor, due to the delay imparted by the spiral portion of the folding belts, it is apparent that unless the speed of the folding belts with respect to the speed of the horizontal conveyor, can be varied dependent upon the size of the blank being folded, the outer panels may not be aligned with the other panels.
  • a conveyor which successively advances open box blanks in sequence and means are provided as the blanks are advanced to fold the outer panels of the blank inwardly so that the edges thereof are substantially in juxtaposition and thereupon to effect relative movement of the folded panels with respect to the adjacent panels to which they are hinged to effect substantially precise alignment of the folded panels with the panels with which they are associated.
  • the folding means comprises endless belts adapted to engage the outer surface of the panels to be folded and means are provided individually to control the speed of such endless belts so that relative movement can be imparted between each folded panel and the panel to which it is connected, to effect such precise alignment.

  • the variable speed drive units may be of any conventional type, illustratively a variable speed drive unit of the type put out by the Link Belt Company under the trademark P.I.V. is employed.
  • Each of the variable speed drive units has an input shaft 143, an output shaft 144 and a control shaft (not shown) rotation of which changes the speed of rotation of the output shaft 144 with respect to the speed of rotation of the input shaft 143.
  • the control shaft may be manually controlled, but in the illustrative embodiment is preferably electrically controlled by a suitable electric motor 145 controlled by pushbuttons 146 on standard 28 so that the motor 145, which is of the reversible type, can turn either in one direction or another to either increase or decrease the speed of the output shaft 144 with respect to the input shaft 143.

  • the main drive motor (not shown) is energized to rotate the shaft 132 (FIG, 4) and through right angle drive :131, rotates the sprocket wheels 133 and 134. Rotation of these sprocket wheels will, through sprocket chain 135 and sprocket wheel 136, rotate shaft 34 on which pulleys 54 and 55 are mounted so that the upper runs 66 of conveyer belts 65, 65' riding around these pulleys will be advanced to- Ward the outlet 26 of the conveyer 21.
  • Rotation of the sprocket wheel 134 will, through sprocket chain 153, rotate the sprocket wheels 151 of variable drive units 141, 142 and therefore will cause the output drive shafts 144 of said units and the sprockets 152 mounted thereon, also to rotate.
  • Rotation of sprocket wheel 152 of drive unit 141 will, through sprocket chain 156, cause sprocket wheel 157 and gear 159 thereon to rotate which in turn will rotate gear 161 and shaft 31. Since the pulley 42 is keyed to said shaft 31, it will rotate therewith, thereby causing the upper run 108 of conveyer belt 102 to move toward the outlet 26.

Since the upper bars 68 have been vertically adjusted so that the rollers 75 thereon will effectively press the box blanks 11 against the conveyer belts 65, 65', such box blanks will be securely gripped for advance by said belts 65, 65'.
  • the connector flap 18 thereof will be moved between the glue roller 81 and pressure roller 83 which, in conventional manner, will apply a coating of glue to the undersurface of such flap.
  • the end panels A and D of the box blank 11, which extend outwardly beyond the skirts 73 (FIG. 7) will be moved into juxtaposition to the folding belts 101, 102.
  • the folding belts 101, 102 due to their incline will cause the panels A and D to fold upwardly about their score lines 12 and 14.
  • the cone roller 112 (FIGS. 1 and 11) is in advance of the cone roller 112', the panel A will be folded inwardly by the belt 101 at a faster rate than the panel D (FIG. 8).
  • the folding belt 101 (FIG. 8) will have been deflected by the cone roller 1 12 to bend the panel A inwardly past vertical position and the folding belt 102 will have been deflected by the cone roller 112' to bend the panel D to substantially vertical position.
  • the transverse distance between the score lines 12 and 14 will be maintained at a desired amount based on the preset transverse spacing between the parallel bars 68.
  • the upper run 108 of the folding belt 101 will first move the panel A to substantially a horizontal position and thereafter the upper run 108 of the folding belt 102 will move the panel D to substantially a horizontal position so that the glued connector flap 18 of panel A will be engaged by the corresponding portion of panel D adjacent its edge 19 as shown in FIG. 14.
  • the speed of the output shaft 144 of drive unit M2 is increased so that the speed of shaft 36 driven thereby will be correspondingly increased as will be the speed of pulley 43 driven by said shaft through the transmission comprising sprocket wheels 44-, 46 and sprocket chain 45.
  • the speed of conveyer belt 102 can also be slightly increased as desired by merely adjusting the variable speed drive unit 14d which, through the transmission comprising sprocket wheels 144 of drive unit 141, sprocket chain 156, sprocket wheel '157, gears 159, 161 and shaft 31, will vary the speed of the pulley 42 and hence of the belt 102.
  • either or both of the panels A and D can be moved back- Ward with respect to the panels B and C therebelow by appropriate adjustments of the variable speed drive units 141, 142 to slow up their movement.
  • the folded boxes are of the type that have the adjacent edges of panels A and D connected by means of a tape subsequently applied, then in such case, of course, these boxes would not have the connector flap 18 and after the folded squared boxes emerge from the conveyer they will then be taken up by a conventional automatic taping equipment for subsequent connecting of the adjacent edges of the panels A and D by means of a tape.
