Definitions

  • FIGURE 1 is a plan view of a blank which is to be folded and glued
  • FIGURE 2 is a plan view on enlarged scale showing the blank of FIG. 1 in a folded condition
  • FIGURE 3 is a perspective view diagrammatically illustrating a portion of an embodiment of the invention.
  • FIGURES 4 and 5 are diagrammatic side views showing different stages of operation of the embodiment of the invention.
  • the folding and gluing to be carried out consists in folding the part 1 on the part 2 around the folding line 3, after having applied glue to the bottom of the flap 4. Thereafter, and by a second folding around the folding line 5, the glued part of the flap 4 is brought to a position in registry with zone 4 (hatched profile).
  • the folding lines are short in relation to the length of the folded down elements. It results therefrom that the slightest deviation from the folding direction is followed by an improper position of the folded parts, as this is shown in FIG. 2 representing the folded and glued piece to an enlarged scale.
  • this figure shows an improper folding in the sense that the edges A of the folded down parts are not aligned with the direction of the edge B of the underlying part 6.
  • FIG. 2 shows moreover the position of pairs of belts 7 and 8 conveying the piece in the direction of the arrow 9, ie in the direction of the folds or perpendicularly to the folding direction of the folded parts.
  • An object of the present invention is to originate a folding-giuing machine avoiding the already mentioned disadvantage.
  • FIG. 4 In FIG. 4 are seen the pairs of belts 7 and 8 travelling in the direction of the arrow 9, namely an upper belt 7 and a lower one 7', as well as an upper belt 8 and a corresponding lower one 3'. These belts run over leading rollers 10, 11, i2 and 13. Above the rollers 10 and 11, there would be of course similar pressing rollers, omitted here for the clarity of the drawing.
  • the glued and folded pieces are conveyed between the belts of the belt pairs, of which a complete piece appears at x and another one partially at y. They are illustrated as simple rectangles, but will be of course shaped in accordance with the box to be obtained, corresponding for instance to what is shown in FIG. 2.
  • FIGS. 4 and 5 show this operation.
  • a piston is displaced by compressed air from an oscillating cylinder 17 and maintains the shutter 14 in the trajectory of the processed pieces (x is shown at rest against the shutter in FIG. 4), while one or some springs 18 act to pull the cylinder and the shutter 14 therewith backward.
  • the shutter of the represented example has been assumed planar, but it could of course be provided with the profile of the front edge of any piece to be processed.
  • an improvement comprising conveying means for advancing a succession of blanks along a path in spaced relation wherein such blanks have been folded and have folded portions with leading edges which are to be in aligned relation, stop means for engaging the leading edges of the folded portions of successive blank-s to momentarily arrest each blank at said edges to align such edges, and means supporting the stop means for displacement between first and second positions in which said stop means is respectively disposed in the path of the blanks and retracted therefrom, the latter means comprising sensing means disposed in the path of the blanks at a spaced location upstream of the stop means for sensing the presence of a blank thereat for displacing the stop means to said retracted position thereof, whereby each blank will be arrested by the stop means until the next successive blank is sensed by the sensing means.
  • said stop means comprises a pivotally supported shutter movable between said first and second positions, said means supporting the stop means comprising a pivotally supported cylinder, a piston displaceable in said cylinder between extended and retracted positions, means connecting the piston to the shutter such that the latter is in the first position thereof with the piston extended and in the second position with the piston retracted, and elastic means connected to said piston for acting thereon to urge the cylinder to a position in which the shutter is retracted 3.
  • said cylinder is adapted for being supplied with air under pressure to displace the piston, said sensing means comprising a contact activated 'by the blanks and controlling air supply to the cylinder.
  • an improved method comprising advancing a succession of blank-s along a path in spaced relation wherein such blanks have been folded and have folded portions With leading edges which are to be aligned, engaging the leading edges of the folded portions of successive blanks at a particular location in said path to momentarily arrest the blanks one by one and align such edges thereof, and releasing each blank when the next successive blank is positioned at a specific spaced position from said particular location.
