Abstract
In order to simplify the apparatus and increase throughputs, sections are stacked by delivering the sections transversely to their length, separating them from one another, turning them over individually if desired and forming them into groups, all the sections in one group either being turned-over or not turned-over, the groups then being stacked in superposed layers by a single transfer device which lifts each group up and puts the group down on a stack.
Claims9
Apparatus for mechanically stacking sections in layers, which sections are delivered transversely to their length, the apparatus comprising:
- at least one conveyor for conveying sections transversely to their length,
- means for separating the individual sections from one another,
- a rotary member, after the separating means, for turning the individual sections over, at will,
- turning means on the rotary member, the turning means defining a section-engaging and retaining recess, for receiving successive sections from the conveyor and turning the respective sections about their longitudinal axes as the section is carried around the rotary member,
- means for rotating the rotary member,
- a second conveyor disposed at the delivery side of the rotary member for receiving the sections from the turning means, the second conveyor having projecting dogs for engaging the sections and removing them from the turning means,
- means for driving the second conveyor such that the portion of the conveyor adjacent to the rotary member moves in the opposite direction to the adjacent portion of the rotary member,
- at least one pass-over means on the rotary member for lifting sections above the turning means and thereby preventing delivery of the sections to the recess of the turning means, and for conveying the sections unturned to the second conveyor,
- actuating means for moving the pass-over means from an inoperative position in which the pass-over means allows the sections to be delivered to the recess of the turning means to an operative position in which the pass-over means prevents delivery of the sections to the recess of the turning means,
- means for assembling the sections individually and successively into groups of parallel sections, the section in each group either touching or there being a predetermined distance between the individual sections,
- a stacking table, and
- a single stacking device for stacking the respective groups of sections on the stacking table.

Apparatus for mechanically stacking sections in layers, which sections are delivered transversely to their length, the apparatus comprising:
- at least one conveyor for conveying sections transversely to their length,
- two stops for separating the individual sections from one another, the stops being spaced apart whereby one, first stop is downstream of the other, second stop in the path of the sections,
- a first pivoted lever mounting the first stop for up and down motion into and out of the path of the sections,
- a second pivoted lever mounting the second stop for up and down motion into and out of the path of the sections,
- drive means for oscillating one of the stop-mounting levers to move the respective stop up and down,
- an intermediate pivoted lever,
- first connecting means operatively connecting said one stop-mounting lever to the intermediate lever for oscillating the intermediate lever approximately 180.degree. out of phase with said one stop-mounting lever,
- second connecting means for operatively connecting the intermediate lever to the other stop-mounting lever for oscillating said other stop-mounting lever approximately in phase with the intermediate lever,
- turnover means, after the separating means, for turning the individual sections over, at will,
- means for assembling the sections individually and successively into groups of parallel sections, the sections in each group either touching or there being a predetermined distance between the individual sections,
- a stacking table, and
- a single stacking device for stacking the respective groups of sections on the stacking table.

- at least one conveyor for conveying sections transversely to their length,
- means for separating the individual sections from one another,
- turnover means, after the separating means, for turning the individual sections over, at will,
- the turnover means comprising a rotary disc, at least one lever with a retaining recess pivotally mounted on the disc and adjacent the periphery thereof for turning the sections about their longitudinal axes, at least one retaining arm pivotally mounted on the disc and adjacent the periphery thereof for preventing delivery of the sections to the lever and carrying the sections over the disc without substantially turning them about their longitudinal axes, means for pivoting the retaining arm inwardly and outwardly with respect to the periphery of the disc, and means for rotating the disc,
- means for assembling the sections individually and successively into groups of parallel sections, the sections in each group either touching or there being a predetermined distance between the individual sections,
- the assembling means comprising a conveyor disposed at the delivery side of the disc and having projecting dogs for engaging the sections and removing them from the disc, and means for driving the conveyor such that the portion of the conveyor adjacent to the disc moves in the opposite direction to the adjacent portion of the disc,
- a stacking table, and
- a single stacking device for stacking the respective groups of sections on the stacking table.
