Abstract
A device for turning panels on machines for processing the panels basically comprises an element for holding a panel to be processed or being processed, located close to a table that supports the panel, and acting on the panel in such a way as to form a pivot in a preset area of the panel, and means for turning the panel about the pivot in such a way as to vary the position of the panel relative to a panel cutting device.
Claims14
A device for turning panels comprising:
- a horizontal table to support at least one panel to be processed;
- at least one movable unit designed to move the panel on the table along a feed line in a feed direction and a direction opposite the feed direction to feed a cutting device that cuts the panel into two or more smaller sub-panels by sawing the panel in a direction transverse to the feed direction;
- the movable unit comprising a crossbar that moves in the feed direction and the direction opposite the feed direction along the feed line and that comprises at least one pickup element for holding the panel by a portion of its rear edge in order to at least one of move the panel into position and hold the panel in position during the cutting operation and during its forward and backward motion on the table;
- an element for holding a panel, located close to the table, and acting on the panel to form a pivot in a preset area of the panel;
- and,
- means for turning the panel about the pivot to vary a position of the panel relative to the cutting device.
3 more elements
The device according to clam 1 wherein:
- the at least one pickup element is adjustably mobile in both directions along the crossbar;
- the means for turning the panel are connected to and move together with the at least one pickup element, and are vertically adjustable along the vertical axis to enable the panel to be rotated as the crossbar moves along the feed direction or along the direction opposite the feed direction while the means for turning the panel move in a direction transverse to the feed direction.
A device for handling a stack of at least one wood panel, said device comprising:
- a support table for supporting the stack;
- means for moving the stack on the support table in first and second opposite directions along a feed path, said means for moving the stack comprising a crossbar that moves in the first and second directions along the feed path;
- means for selectively engaging a select portion of the stack to define a pivot axis about which the stack pivots relative to the support table;
- and,
- a panel turning member connected to the crossbar and movable on the crossbar in third and fourth opposite directions that are transverse relative to the feed path, said panel turning member engaging an edge of the stack and pivoting the stack about the pivot axis when said means for engaging are operative to engage the select portion of the stack to define said pivot axis.
