Frame arranged in a machine for temporarily supporting a plate-like workpiece in a horizontal plane

A device for temporarily supporting a plate-like workpiece in a horizontal plane in a machine, which workpiece is subsequently destined to be dropped in a vertical direction between guiding and squaring stops located within the machine, said device including a frame, a pair of flat bars with each bar having a length to extend over most of the whole length of the frame and having a planar support surface, mounting means for mounting the flat bars in the frame to extend along a travelling direction of the workpiece and for movement of the planar support surfaces in a horizontal plane between a position with said support surface of the bar in a retracted, withdrawn position to an engaged position with the support surface providing support for said sheet, and actuator means for shifting the flat bars between the two positions, said mounting means having support pieces for mounting ends of the bars and actuators of the actuator means, said support pieces being engaged on axles for movement therealong to enable shifting of the bars according to the size of the plate-like workpiece.

A device for temporarily supporting a plate-like workpiece in a horizontal plane in a machine, which workpiece is subsequently destined to be dropped in a vertical direction between guiding and squaring stops located within the machine, said device including a frame;

• a pair of flat bars, each bar having a length to extend over most of the whole length of the frame and having a planar support surface being formed by a side of the bar;
• mounting means for mounting the flat bars in the frame to extend along the travelling direction of the workpiece with one end of each bar being pivotable around a vertical axis for movement of the planar support surfaces in a horizontal plane between a position with said support surface of the bar in a retracted, withdrawn position to an engaged position with the support surface providing support for said sheet;
• and actuator means for shifting the flat bars between the two positions, said actuator means including a horizontal linear actuator coacting with a spring, said spring and actuator being connected to the other end of each bar to pivot the bar between the retracted position and the engaged position.

• mounting means for mounting the flat bars in the frame to extend along a travelling direction of the workpiece and for movement of the planar support surfaces in a horizontal plane between a position with said support surface of the bar in a retracted, withdrawn position to an engaged position with the support surface providing support for said sheet, said mounting means pivotably mounting one end of each flat bar by a connecting rod and pivotably mounting the other end of each flat bar with a first branch of a lever extending parallel to the connecting rod, said lever having a second branch extending at an angle to the first branch;
• and actuator means for shifting the flat bars between the positions, said actuator means including an actuator with an actuator rod connected to the second branch so that shifting of the actuator rod causes the bar to move in a parallel direction at right angles to the length of the bar between said positions.
