Stop device for woodworking machines

The invention relates to a stop device for woodworking machines for the end-side processing of wood, in particular of window timbers, vie tenon and slotting machines, with a cutting device for the timbers that are in Machining direction of the post spindle is upstream, and ait a Bolltiech that guides the window timbers past the cutting device and the tenon clip spindle. At a Such an arrangement has already been proposed for the rough setting of the length required in each case in the workflow in front of the cutting device a stationary guide extending perpendicular to the direction of movement of the roller table for one slide along the guide, the Bolltiech in the Starting position overarching and rait its abutment surface stop lying in the direction of movement of the fioll table to be provided, the stop by means of a tension cord

Toothed belts reinforced with inserts · driven and in various positions specified by an electronic control system can be determined in relation to the leadership.

Now, in many cases, it is desirable to make such a woodworking machine work automatically wear.

For this purpose, it is provided according to the invention that the stop has a the end face of the window timber to be processed carries the trigger, with which the movement of the roller table is carried out its starting position can be released "

With this arrangement it is achieved that after the definition of the stop and after the counter movement of the to be processed Workpiece against the stop by actuating the trigger, the movement of the Boll table begins automatically, so that the the end face of the window frame opposite the stop side is provided with pegs and slots.

This release device can be used in a particularly advantageous § Apply Veise to a woodworking machine where

Lifting directions of the window timbers in front of the tools these spindles run at right angles to each other, so that the window timbers provided with tenons and slots are passed to the milling spindles at right angles and beyond the milling spindles for longitudinal profiling a second roller table and a second tenoning spindle with a cutting device are provided.

In such an arrangement, the stop according to the invention is and release device expediently assigned to the second roller table, so that its movement transversely to the feed direction is automatically triggered when longitudinal profiling when the longitudinally profiled window timber with its front side on the The trigger hits the attack

When this happens, the roller table starts moving so that first the second end face is cut to length by a cutting device connected upstream of the second tenon hammer spindle, whereupon the second end face is provided with pegs and slots.

The invention is explained in more detail below with the aid of an exemplary embodiment in the drawing.

The figure shows a schematic representation in plan view Woodworking machine to which the invention is applied »

According to the figure, there is a woodworking machine for Tenoning and length profiling of window timbers aue one first tenoning spindle 1, which is preceded by a cross-cut saw 2 is, with more than one corner to the Zapfenechlagepindel 1 Length profiling spindles 3 are arranged and where the Tenon impact spindle 1 opposite side of the longitudinal profile ilierspindeln 3 containing structural unit a second tenon hammer spindle 4 is arranged with an upstream cross-cut saw 5. A roller table 6 or 7 is provided on both sides of the structural unit containing the longitudinal profiling spindles 3, the surface of which is aligned with the surface of the work table 8 of the longitudinal profiling spindles 3. The rolling tables 6 and 7 are therefore assigned and lead to the units formed in each case from the cross-cut saw and the tenon hammer spindle the workpieces to be machined past these units.

To determine the length of the window timber to be processed, it must be aligned with the processing direction for longitudinal profiling an adjustable stop 18 is provided, the

The stop 18 is accordingly assigned to the second roller table 7, so that its movement in the direction of arrow 11 is triggered automatically, the longitudinally profiled workpiece knows from the work table 8 of the longitudinal profiling spindles 3 coming with a sainer face hits the trigger 10 of the stop 18.
