Definitions

  • This invention relates to the art of squaring equipment for folded boxes of the type that comprises 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 conveyer, due to the delay irnparted by the spiral portion of the folding belts, it is apparent that the outer panels may not be aligned with the other panels.
  • a conveyer which successively advances folded box blanks in sequence and means are provided as the banks are advanced to move either or both of the folded over top panels of successive folded box blanks relative to each other and to the bottom panels to effect squaring of such box blank.
  • the conveyor comprises a bottom conveyer belt and a pair of spaced parallel upper conveyer belts, the latter being aligned with the top folded over panels of the box blank.
  • the speed of the upper conveyer belts is adjustable so that the speed of either of the folded over top panels may be increased or decreased with respect to the other top panel and with respect to the bottom panels which rest on the lower conveyer belt.
  • an ali i ment bar is provided at the outlet end of the conveyer, against which the leading edge of the folded box blank will be forced by the movement of the conveyer, such alignment bar moving out of the path of such box blank after it has been squared.
  • FIG. 1 is a perspective view of the squaring equipment with parts broken away
  • FIG. 2 is a fragmentary side elevational view showing the outlet end of the squaring equipment
  • FIG. 3 is a view taken along line 33 of FIG. 2,
  • FIG. 4 is a top plan view of the box blanks in various positions
  • FIG. 5 is a sectional view taken along line 5-5 of FIG. 2, and
  • FIG. 6 is a fragmentary detail side elevational view on an enlarged scale of the belt speed adjusting mechanism.
  • the squaring equipment comprises a frame 19 supported in substantially horizontal position by upright standards 11.

  • a flange 24 Secured to shaft 21 is an elongated sleeve 23 from which extends a flange 24 which defines an alignment or stop bar that extends transversely across the outlet end of the conveyor belt 16.
  • Means are provided normally to retain the stop bar 24 in upright position in the path of movement of a folded box blank B, carried by the conveyer belt 16.
  • an elongated substantially rectangular block 25 having rounded ends is secured to one end of shaft 21. Riding around the top surface of the block 25 and depending from each end thereof is a strap 26, one end of which is secured to the bracket 22 and the other end to one end of a coil spring 26 which has its other end secured to a fixed support.
