Definitions

  • the stacking is effected by feeding the articles individually, in a separated manner, to a first stacking bucket until a predetermined number of articles is attained. The flow is then directed to a second bucket to allow for unloading of the first bucket and when the second stack is completed the cycle is reversed. Further, some of these machines handle incoming articles in a nonoverlapped manner whereas many articles are fed out from web presses or other machines in an overlapped arrangement which means that an intermediate apparatus would be required for separating the articles before being fed to the stacking machine.

  • transporting conveyor portions each comprise two endless conveyor belts each defining a path whereby said belts are oppositely positioned along a portion of said path to frictionally engage said articles therebetween to transport them to said ejecting conveyor.
  • a machine as claimed in claim 2 wherein said transporting conveyor portion of said first conveyor means is driven at a conveying speed at least twice the conveying speed of said transporting conveyor portion of said second conveyor means.
  • said ejecting conveyor portion comprises two endless conveyor belts oppositely positioned to frictionally engage and transport said articles therebetween to eject them at said outlet into said stacking bucket, said ejecting conveyors being driven at a constant conveying speed independent of a slightly higher than the conveying speed of said transporting conveyor portion.
  • said inverting means comprises two endless belts, each belt being held in tension between two pulleys and inverted each said pulleys being closely oppositely positioned and offset from their. respective axis of rotation so that said belts are in contact with each other along a portion of its path to thereby transport said articles therebetween.
  • a machine as claimed in claim 9 wherein said two endless belts transport said articles from a receiving conveyor at the inlet of said first conveying means, said articles being inverted 180 about its axis of travel so that all of said articles in said bucket are stacked with the corresponding face on the same side of the stacii.
  • a machine as claimed in claim 2 wherein said diverter comprises a diverter element positioned adjacent a receiving conveyor to divert the normal flow of articles to said first or second conveying means.
  • a machine as claimed in claim 12 wherein said diverter element is secured to a shaft at one end of which is fastened a cam which may be actuated to either a first or second position, said first position causing normal flow of said articles to said first conveying means, said second position causing said diverter element to interfere with the normal flow of articles and diverting it to said inlet of said second conveying means.
  • a machine as claimed in claim 13 wherein said cam is provided with a cavity in a portion of its outer periphery defining two pin engaging slots and a ridge therebetween to cause a pin associated with a solenoid linkage to engage therein upon actuation of an associated solenoid to displace said diverter element to said first or said second position, said first or second positions each being adjustable by means of two adjustable bumper members each cooperating with a respective side of the free end of a diverter positioning member secured at its other end to said diverter shaft.
  • a machine as claimed in claim 2 wherein there is further provided a receiving conveyor section for receiving and counting said articles as they are received by the machine.
  • said receiving conveyor section comprises an endless belt associated with a frame, said frame having adjustment means to adjust the height of its receiving end, a light and photocell assembly provided at said receiving end for counting each article, and a gate mechanism positioned along said endless belt and in close proximity to said diverter for delaying the conveyance of an article when said diverter is actuated to a predetermined position.
  • a machine as claimed in claim 2 wherein said stacking bucket comprises a base in the form of an endless belt trained about two idle rollers, said base being pivotally secured to a supporting bar on which said base is caused to tilt from a horizontal unloading position to a loading position to provide a low corner at the intersection of two article holding plates extending above said endless belt.
  • a machine as claimed in claim 17 wherein there is further provided an unloading conveyor having a driven roller secured to one end thereof, said driven roller being in frictional engagement with said endless belt of said bucket when said bucket is displaced to its horizontal position to thereby effect unloading of the stacked articles.
  • a method of stacking a predetermined quantity of newspapers and the like articles in bundles comprising the steps of:
