A device for holding down and guiding workpiece plates to be machined on a wood working machine and advanced along a straightedge to ensure that the workpiece plates during the feed movement remain with one of their trimmed longitudinal edges in steady contact with the straightedge for the purpose of accurate alignment. The device includes a holding-down and guide member placed by means of a roller exerting a predetermined pressure in close contact with the upper side of a workpiece plate, with the central axis of rotation of the roller and the longitudinal axis of straightedge forming an acute angle as viewed in the direction of feed.

In sawing and drilling machine for splitting up and drilling panel-type workpieces, a saw carriage and a drilling device for planar face and/or end face drilling are guided below a machine table having a saw slit, along a straight-line guide parallel to the saw slit.To minimize the structural expenditure involved in guiding and driving the saw carriage and the drilling device, it is proposed that the drilling device be guidable along the straight-line guide of the saw carriage and that it be jointly adjustable with the saw carriage and that the saw slit be variable in its width.

An arrangement for conveying and stacking final products created by subdivision of a succession of plate blanks into a plurality of such products comprises an input conveyor for supplying the products in a longitudinal transport direction at a predetermined upper level to a stacking station and an output conveyor offset laterally from the input conveyor for transporting stacks of the products away from the stacking station in the direction and having an upstream end laterally adjacent the stacking station at a lower level below the upper level of the input conveyor. A sorter at the station receives the products from the input conveyor at the upper level and moves them at the upper level to either of two stacking substations longitudinally aligned with the upstream end of the output conveyor. Respective stacking units at the substations each in turn have a stacking table displaceable vertically between the upper and lower levels and horizontally displaceable transversely of the transport direction between a basic position at the respective substation for receiving the final products therefrom and an extended position aligned longitudinally with the output conveyor for delivering the final products thereto and a conveyor section fixed to and displaceable jointly transversely with the stacking table such that in the basic position of the respective stacking table it forms a longitudinal continuation of the output conveyor.

The invention relates to an improved roller table arrangement for the transportation, in a horizontal plane, of typically plate-shaped workpieces. The present invention provides a roller table of the form of rollers located on carrier rails, in which rolling transport may be accomplished either parallel to, or transversely to, the carrier rails, the aforesaid transportation being achieved through the use of interchangeable roller receiving means. The invention further provides a means by which uniform elevation of the rollers with respect to the carrier rails is accomplished in spite of the presence of swarf or other material debris upon the carrier rails. The present invention further provides for the selective conversion from roller table to workpiece support table through the use of support strips which may be placed upon the carrier rails in lieu of the roller receiving means.

A conveyor system is composed of a trolley and an elongated inverted U-shaped or C-shaped track which is formed without any machining involving removal of material by simple deformation of a sheet-metal blank. The track has a horizontal or vertical web, two vertical or horizontal legs extending from the marginal portions of the web, and two horizontal or vertical ledges which constitute the inwardly bent end portions of the legs. One of the ledges has a V-shaped cross-sectional outline and the other ledge has an inturned carrier for a toothed rack in mesh with a pinion driven by a motor on the trolley. The trolley has a first pair of rollers whose conical peripheral surfaces engage the opposite sides of the V-shaped ledge, and a second pair of rollers whose cylindrical peripheral surfaces engage the opposite sides of the other ledge. One roller of each pair is adjustable to ensure that both rollers of each pair engage the corresponding ledge with negligible clearance. The V-shaped portion of the one ledge can receive a steel rod which reinforces the track and is engaged by one roller of the respective pair of rollers.
摘要:
A process and apparatus for transporting stacked workpieces with aligned edges on a low friction workpiece support platform in which the shifting of individual panels relative to each other under the influence of inertia is precluded. The process includes the step of pressing the workpiece stack on the workpiece support platform. An apparatus that presses the workpiece stack is moved in its entirety along the direction in which the workpiece stack is transported.

A roller bearing device for use with workpiece plate transfer platforms including one or more support rails, each support rail having a longitudinal groove with a longitudinal opening on the upper surface of the support rail. At least one roller support is seated in the longitudinal groove. The roller support includes an angled lever pivotably mounted on a support base. A roller is supported at the end of a first arm of the lever, with at least a portion of the roller positionable above the top surface of the support rail. The end of the second arm is articulated to an adjustment member, actuation of which causes the lever to pivot, raising or lowering the roller.

A drilling machine for planar face and/or end face drilling on panel-type workpieces or panel blanks which offers advantageous machining possibilities is described. Associated with the drilling machine on its operating side opposite the workpiece advancing device are a workpiece aligning table with a side stop, at either side, and a clamping device for fixing workpieces or panel blanks on the workpiece supporting table. It is, for example, thereby possible for two workpieces which belong to one piece of furniture, and in which assembly bores are to be made in mirror-image relationship, to be jointly placed on one of the workpiece aligning tables, in each case, aligned at their respective side stop and then clamped in the workpiece slider of the workpiece advancing device. The idle times of the machine can thus be reduced to a minimum.

In a movable sawing unit for severing planar workpiece panels, which has a severing blade and a prescoring saw blade for cutting a prescore groove to prevent splintering of panels by the severing blade, a device for adjusting the depth of penetration of the prescoring saw blade. The prescoring saw blade is operably positioned in advance of the severing blade, upon a vertically movable support. A tactile element associated with the vertically movable support moves along a directing surface extending along the direction of advance of the workpiece panel, causing the prescoring saw blade to occupy a plurality of cutting positions.

A process is described, with the aid of which panel-type workpieces to be manufactured from a panel blank may also be provided with flat face and/or end face bores in the course of their manufacture. For this purpose, the panel blank is displaced transversely to the cutting plane into a stop position, the flat face bores pertaining to one of the workpieces to be manufactured are subsequently made in the one flat side of the panel blank. To make the further flat face bores for the workpiece, the panel blank is then transported further in a clocked manner through predetermined paths in the same direction and bored after each advance. Upon completion of all of the flat face bores, the panel blank is displaced in a clocked manner in the opposite direction into predetermined positions, fixed after each advance, and lastly severed.For the end face boring, the panel blank is displaced in the direction of advance through a path corresponding to a side length of a workpiece and subsequently clamped and severed. The resulting workpiece is then displaced in the direction of advance through a predetermined path, clamped and bored at the end face located opposite to the bored end face. The remaining part of the panel blank is displaced in the direction of advance into a stop position, likewise bored at the end face, and lastly displaced again in the direction of advance through a path corresponding to a side length of a workpiece, clamped and severed, whereupon the same procedural steps are repeated.
