With the machine described below, woods are processed, from which, for example, window or door frames or wings are assembled. In the machine can also Be processed for steps, furniture parts in frame or cleat construction or the like can be used. The Machine according to FIG. 1 has a transverse profiling unit 1 and a longitudinal profile unit perpendicular to it 2. With the cross profile unit the woods 3 are processed on the front side. In the longitudinal profile unit 2, the woods are then on their long sides profiled.

The wood to be processed 3 are in the Querprofiliereinheit. 1 with a clamping device 4 in a predetermined position preferably clamped centrally on a carriage 5 'by a vertical Axis 6 is pivotable. The carriage 5 'can along a cross slide 5 are moved, which is movable along a guide 7. Both carriages 5, 5 'are thus in mutually perpendicular directions adjustable.

The Querprofiliereinheit is provided with at least one saw 8, with the respective end of the wood 3 can be sawed off. Depending on Location of the wood 3 relative to the saw 8, the front sides of the wood 3 perpendicular, but also acute or obtuse to the Sawed longitudinal direction of the woods. In this case, that will Wood 3 with the clamping device 4 about the axis 6 in the desired Angle pivoted. This is a (not shown) motor Drive provided with which the clamping device 4 automatically in the desired position can be pivoted. Advantageous is the Clamping device 4 connected to a CNC controller.

The saw 8 has a circular saw blade 9, which is about a horizontal axis is rotatably driven. Following the saw 8 is the Querprofiliereinheit 1 provided with at least one vertical spindle 10, on the known manner, a pin / slot tool 11 rotatably sitting. With him the previously sawn end of the wood 9 is cross-profiled, For example, tapped or slotted or with a counter profile Mistake. The spindle 10 with the tool 11 can be known in the Way be adjustable in the axial direction. In this case, sit on the spindle 10 on top of each other two or more tools with which edited the ends of the wood 3 in the desired manner can be. In addition, the spindle 10 can also be adjusted radially be to the spindle 10 to different diameters to adjust the respective tool 11. The cross profile unit 1, as in the illustrated embodiment, with a second spindle 10 may be provided for another tool 11. These second spindle 10 is moved back and thus not in use. Instead of driving back this spindle 10, the clamping device can also 4 by means of the carriage 5 'on the cross slide 5 retracted become.

Following the spindle 10 is the Querprofiliereinheit 1 with at least a drilling and / or dowel unit 12 provided. With her can the wood 3 following the Querprofiliervorgang with at least a bore and / or be provided with at least one dowel.

The Querprofiliereinheit 1 can also only the saw 8 and / or the Spindle 10 and / or the unit 12 have.

The cross slide 5 is from the initial position shown in Fig. 1 from along the guide 7 in the direction of arrow 13 is moved. It will the clamped wood 3 successively first with the saw 8 end sawn, then transversely profiled and drilled and / or dowelled. Depending on the design of the machine, the cross slide 5 in Transport direction 14 moved back to its original position and the clamping device 4 is pivoted about the vertical axis 6 be that in a renewed passage of the wood 3 through the Querprofiliereinheit 1 sawed the other end of the wood 3 and is cross-profiled. In this case, the wood 3 is first at both Edited ends before passing it to the Längsprofiliereinheit 2 becomes. Such a procedure is shown in FIG. The Wood 3 is in the described manner twice through the Querprofiliereinheit 1 transports and edited both ends. Subsequently is the double-sided processed wood 3 of Längsprofiliereinheit 2 pass, in which the wood 3 in to be described Longitudinally profiled.

When the cross slide 5 has reached the transfer position, the Clamping device 4 is rotated so that the wood is parallel to the transport direction in the Längsprofiliereinheit 2 lies. In this situation can then the wood from a feed unit 15 of the Längsprofiliereinheit. 2 be taken over. With her, the wood is 3 in its longitudinal direction transported by the Längsprofiliereinheit and thereby at its corresponding Long side worked. The Längsprofiliereinheit 2 has in the machine according to FIG. 1, in the transport direction of the wood 3 seen first drilling 16 and at least one vertical Spindle 17, rotatably on the at least one Längsprofilierwerkzeug 18 sitting. In the illustrated embodiment, the Längsprofiliereinheit 2 provided with two spindles 17, on each of which at least a Längsprofilierwerkzeug 18 sits. With the drilling units 16 be in the transport direction right longitudinal side and in the Top and / or bottom of the wood made 3 holes. The Längsprofilierwerkzeug 18 profiled in the transport direction right longitudinal side of the wood 3. The Längsprofiliereinheit 2 can with be equipped with other spindles. Fig. 1 shows an example behind the second longitudinal profiling spindle 17 has a horizontal groove spindle 84.

Fig. 2 shows a first embodiment of the machine, wherein the Wood 3 in the Querprofiliereinheit 1 in the manner described processed twice in succession at both ends becomes. Subsequently, the wood 3 of the feed unit 15 is transferred, the wood on the drilling units 16 and the two Longitudinal profiling tools 18 of Längsprofiliereinheit 2 passes. The Längsprofilierwerkzeuge 18 and the drilling units 16 are so arranged that the wood 3 when passing on its right longitudinal side, as described above, is processed. Following the Longitudinal profiling tools 18 is the machine with a second Längsprofiliereinheit 2 with other Längsprofilierwerkzeugen 18 and provided further drilling units 16. They are arranged that processed with them in the passage of the timber 3, the left longitudinal side becomes. As a result, only a single pass of the wood is 3 through the Längsprofiliereinheiten 2 and thus through the whole machine necessary. After processing both long sides is the Wood 3 by means of a transport device perpendicular to the transport direction 21 in the Längsprofiliereinheiten 2 another station or fed to another magazine 24. This machine provides one Continuous system in which the woods 3 processed in the pass become. The wood 3 is in the whole process and to everyone Time in both the transverse and the longitudinal professional units 1, 2 firmly clamped, so that an optimal processing quality and accuracy is achieved.

In a second embodiment of the machine according to FIG. 3 the processed wood 3 passes through the Längsprofiliereinheit after passing 2 on a cross conveyor 20, with the wood back is transported to the cross-profiling unit 1. Two ways of working one Such machine will be described in more detail with reference to FIG. 3. at the first operation, the wood 3 is initially in the transport direction 13 in the Querprofiliereinheit 1 in the manner described transported. With the circular saw blade 9 of the circular saw 8 is the corresponding Sawed off the end of the wood 3 and with the subsequent Tool 11 cross-profiled, for example, slotted or tapped. Subsequently, with the drilling and / or dowel unit 12th the wood 3 drilled and / or dowelled. Then the wood is 3 passed to the feed unit 15 of Längsprofiliereinheit 2. In the Längsprofiliereinheit is the wood 3 with the drilling units 16th drilled on its long side and on its top and / or bottom. Following this, the longitudinal side with at least one the two spaced apart longitudinal profiling tools 18 longitudinal profiled. The one end and one long side processed wood 3 then passes to the cross conveyor 20, with the the wood perpendicular to the transport direction 21 in the Längsprofiliereinheit 2 is transported in the transport direction 22. The cross conveyor 20 passes the wood 3 a transport device 23, parallel to the Feed unit 15 is located and the wood 3 back to Querprofiliereinheit 1 promotes. Here, the wood 3 is received by the clamping device 4 and aligned so that the other, not yet worked Sawed end of the wood 3 with the saw 8, with the tool 11 cross profiled, for example slotted or tapped, and optionally is processed with the drilling and / or dowel unit 12. The now processed at both ends wood 3 is so the feed unit Pass 15 of Längsprofiliereinheit 2 that not yet processed longitudinal side of the timber 3 to the drilling units 16 and the two Längsprofilierwerkzeugen 18 is passed. With the Drilling units 16, if necessary, this longitudinal side of the wood 3 drilled. With the following, rotatable about vertical axes Tools 18, the wood 3 is longitudinal profiled.

In the second, preferred mode of operation are in the Querprofiliereinheit 1 initially processed both ends of the wood 3, wherein the cross slide 5 in the manner described twice the Querprofiliereinheit 1 passes through. Then that will be worked on both ends Wood 3 of the feed unit 15 pass, which in the in Fig. 1 is located transfer position shown. The wood 3 is with the Feed unit 15 on the drilling units 16 and the Längsprofilierwerkzeugen 18 passed and edited on one long side. With the cross conveyor 20 and the transport device 23rd the timber 3 is returned to the Querprofiliereinheit 1 and of the Clamping 4 recorded. With the cross slide 5 is the Wood 3 transported without processing by the Querprofiliereinheit 1 and the feed unit 15 so passed that the wood 3 at Transport through the Längsprofiliereinheit 2 on the other longitudinal side is processed.

While the wood from the cross conveyor 20 to the transport device 23rd is promoted, the feed unit 15 moves to the transfer position back, so that she can take over this wood immediately.

The machine according to FIG. 3 represents a circular system in which the wood is transported twice through the machine. After this The wood passes twice through the machine and it gets done processed wood either on the cross conveyor 20 over another Processing supplied. But it is also possible to finish the finished To pass wood 3 to the cross conveyor 20, which finished the finished Wood 3 of the transport device 23 passes, which the wood in a magazine 24 (Fig. 3) stores.

In the transverse profiling unit 1, two woods can be processed simultaneously be as shown in FIGS. 7 to 11. The woods 3 lie with their long sides together and are in the clamping device 4 clamped. It is designed as a clamp and has a lower jaw 25 and an upper jaw 26. The Woods 3 are stretched between the two jaws 25, 26. The Jaws 25, 26 have flat bearing surfaces 27, 28, so that the Wood can be reliably clamped. The upper jaw 26 is adjustable in height direction 29 (FIG. 8). The whole Clamping device 4 is transverse to the axis of the woods 3, as described, adjustable in direction of arrow 13.

The lower jaw 25 is at the free end with an upward Stop 31 provided that slipping of the woods 3 transversely to the jaws 25, 26 prevents and exact alignment or position of the woods 3 guaranteed. The jaw 25 is about a transverse horizontal axis to its longitudinal direction 32 swiveling. Should the woods 3 in a manner to be described be transferred to the feed unit 15 of the Längsprofiliereinheit 2, can the jaw 25 about the axis 32 so far down in a release position are pivoted that the stopper 31 outside the movement path of the woods 3 is (Fig. 8).

Fig. 7 shows the initial position in the transfer of the woods 3 of the Clamping device 4 of the transverse profiling unit 1 in the feed unit 15 of Längsprofiliereinheit 2. The clamping device 4 and the feed unit 15 have in this starting position distance from each other. In the area between the clamping device 4 and the feed unit 15 is an intermediate clamping device 33, the two superimposed lying jaws 34, 35, of which at least one is adjustable in height direction. In addition, the entire Intermediate clamping device 33 adjustable in height direction. In the area below the intermediate clamping device 33 is a Transfer unit 36, the two spaced apart horizontal, endless circumferential bands 37, 38 has. They are each mounted on a support 39, 40, of which at least one in the height direction is adjustable. This allows the distance between the two bands 37, 38 simply to the thickness of the transported 3 woods are adjusted. The entire transfer unit 36 is also adjustable in height direction.

To transfer the woods 3 of the clamping device 4 to the feed unit 15, the clamping device 4 is initially in the adjustment 30 adjusted against the intermediate clamping device 33. The two Clamping jaws 34, 35 of the clamping device 33 are set that the woods 3 reliably between the jaws 34, 35 retract can. The clamping device 33 is located in the area outside the adjustment of the clamping device 4 and its jaws 25, 26. The tensioning device 4 is adjusted so far until the woods 3 completely between the jaws 34, 35 of the clamping device 33 lie (Fig. 8). Once the woods 3 completely between the Jaws 34, 35 are retracted, one of the jaws, in the embodiment, the upper jaw 34 against the woods. 3 adjusted, thereby reliably between the jaws 34, 35 the clamping device 33 are clamped (Fig. 8). Subsequently becomes the lower jaw 25 of the clamping device 4 about the axis 32 pivoted so far down that the stop 31 of the jaw 25 is located in the area below the woods 3. Now that can Clamping device 4 are returned in the direction of arrow 41. This takes place by appropriate retraction of the cross slide 5, on the clamping device 4 is arranged.

During the transfer of the woods 3 of the clamping device 4 in the intermediate clamping device 33 is the transfer unit 36 still in their initial position in the area below the Zwischenklemmeinrichtung 33 (Figure 8). As soon as the clamping device 4 has returned, the transfer unit 36 in their shown in Fig. 9 Procedure for transfer. For this it is necessary that the transfer unit 36 initially in its lowered position in the arrow direction 42 is moved back so far that the subsequent Adjusting the transfer unit 36 in the height direction (arrow 43 in FIG. 8) the bands 37, 38 on the side remote from the feed unit 15 Up side of the intermediate clamping device 33 at the height of the woods 3 can be. The two bands 37, 38 have this one such a distance from each other that during the subsequent adjustment the transfer unit 36 in the direction of the intermediate clamping device 33 reach the woods 3 between the two bands 37, 38 (Figure 9). The distance between the two bands is adjusted that when adjusting the transfer unit 36 in the transfer position Do not touch the woods 3. Once the shown in Fig. 9 Transfer position is reached, at least one of the carrier 39, 40 of the transfer unit 36 adjusted so that the woods 3 of the Bands 37, 38 can be detected.

Once the bands 37, 38 have been adjusted in this way, can the jaws 34, 35 of the intermediate clamping device 33rd opened and thus the woods are released. Subsequently moves the transfer unit 36 with the tensioned woods 3 in the arrow direction 30 (Fig. 9) back so far that the jaws 34, 35 of the Intermediate clamping device 33 in the area outside the woods 3 are. Subsequently, the intermediate clamping device 33 is down moved away (Fig. 10).

Once the intermediate clamping device 33 in the area outside the Woods 3 is located, moves the transfer unit 36 opposite to the arrow 30 (Fig. 9) to close to the feed unit 15 zoom. Subsequently becomes a slider-like transport unit 77 in the conveying direction 44 (Fig. 10) moves, which the woods 3 in the feed unit 15 of Längsprofiliereinheit 2 promotes. The endlessly circulating Bands 37, 38 of the transfer unit 36 are here on the woods 3 on and are taken while moving circumferentially. The Bands 37, 38 serve to guide the woods 3 and prevent axial displacement during this transfer process. The conveying direction 44 (Fig. 10) of the woods 3 is perpendicular to its longitudinal axis. The feed unit 15 has in a manner to be described above their length evenly distributed clamping jaws, with which the woods 3 are clamped on a support 45. The displacement path the woods 3 in the adjustment 44 is by stops 46, which is distributed over the length of the feed unit 15 arranged are and at which the woods 3 come to the plant.

Since in the longitudinal profiling the woods 3 not, as in the transverse profiling, Next to each other, at first only one becomes Wood 3 transported in the feed unit 15. Once the wood 3 at the stops 46 comes to rest, the jaws drove down and this wood 3 in the feed unit 15th clamped. Subsequently, the feed unit 15 in the feed direction 21 (Figures 2 and 3) until the next one Wood 3 in the same way by means of the transport unit 77 in the feed unit 15 promoted and can be clamped there. FIG. 11 shows the situation in which the feed unit 15 is correspondingly advanced and the second wood 3 in the feed unit 15th has transported.

After this second wood 3 clamped in the feed unit 15 has been, the upper carrier 39 of the transfer unit 36th Move upward, so that the transfer unit 36 against adjustment 42 (FIG. 8) can be reduced. Subsequently the transfer unit 36 is lowered again, so that they for the next delivery cycle is available. Are those to be edited Woods 3 long, can in the feed unit 15 at appropriate Length only one wood can be clamped. Then the sled must 5 Wait in the transfer position until the feed unit 15 after the delivery of the longitudinally profiled wood 3 back into the Transfer area is reduced.

Depending on the wood width, the clamping device 4 of the transverse profiling 1 only one wood 3 or even more than two woods record. is the wood 3 as wide as the clamping elements of the clamping device 4, then takes the clamping device 4 only a wood 3 and passes it after processing in the Querprofiliereinheit 1 in the described Way of the feed unit 15. Have the woods 3 a comparatively small width, can in the clamping device 4 three or more woods 3 are clamped together. Depending on Length of these woods 3 and the feed unit 15, they can one behind the other be clamped in the feed unit 15. Is that enough Length of the feed unit 15 is not off, all woods 3 consecutively to clamp in the feed unit 15, the transfer takes place the remaining woods 3 when the feed unit 15 after the processing of their recorded wood in the Längsprofiliereinheit 2 returns to its transfer position. Then you can remaining wood 3 in the manner described the feed unit 15 are handed over.

As long as the woods 3 are still clamped in the intermediate clamping device 33 are advantageous with the drilling unit 12 of the Querprofiliereinheit 1, if necessary, holes in the wood 3 attached. During this drilling process, the clamping device 4 Move back to the starting position to pick up the next workpieces.

With reference to FIGS. 4 to 6 and 14, the feed unit 15 is closer explained. It has a carrier 47, which is advantageous over the length the feed unit 15 extends. The carrier 47 is with a vertical Rear wall 48 provided at the distributed over the length guide elements 49 are attached. These guide elements 49 are in two horizontal, spaced apart rows arranged (Figures 4, 5 and 14). With the guide elements 49 sits the feed unit 15 on two mutually parallel guide rails 50, 51st (Figure 14) provided on a machine frame (not shown) are.

The rear wall 48 of the carrier 47 is at the upper end in a perpendicular to her lying support member 52 via. At its bottom is at least one drive 53 for jaws 54 attached. The drive 53 has advantageous lifting cylinder 56 (Fig. 14), which at the bottom of the horizontal support member 52 are attached and from which down a piston rod 57 protrudes. It is at the bottom over a cross piece 58 with an upwardly directed rod-shaped support 59th connected by at least one guide 60 and a guide bush 61 up above the support member 52 protrudes and at the top free end carries the respective jaw 54. That way are all jaws 54 by a respective lifting cylinder 56 independently adjustable in height direction. Thus, the individual jaws 54 are adjusted independently. It is also possible to group the jaws 54 in groups and groupwise together to disguise.

On the support member 52 at least one rake-like carrier 62 is mounted, in which the stops 46 are stored for the woods 3. The attacks 46 are advantageous stop bolts, which are perpendicular to the the jaws 54, 55 facing the top of the carrier 62 protrude and under the force of at least one compression spring 63 are. These move the stops 46 axially into a stop position.

The jaws 54 have a square in plan view (FIG. 6) Base 64, the one at its terminal longitudinal edge rectangular projection 65 has. This causes the jaws 54 on both sides of the projection 65 with rectangular recesses 66, 67 provided. All jaws 54 are the same and are by far side by side in a row. The jaws 54 are advantageously screwed onto the upper end of the carrier 59, so they can be easily and quickly replaced if necessary can be.

The clamping jaws 54 lie in the vertical direction opposite the clamping jaws 55, whose upper sides 68 form the support 45 (FIG. 10) for the wood 3 to be clamped. The jaws 55 are at the same height and are advantageously also limited independently adjustable in height direction. But it is also possible to adjust the lower jaws 55 together or in groups in the height direction. The adjustment can be done via cylinder. But it is possible to adjust the jaws 55 via a CNC axis.
The clamping jaws 55 are, as can be seen from FIG. 6, arranged at a gap to the clamping jaws 54, seen in plan view of the feed unit 15. The lower jaws 55 have a T-shape with a rectangular foot 69, which lies in plan view between adjacent jaws 54. The lower clamping jaws 55 are also provided with a web 70 lying at right angles to the foot 69, which, seen in plan view, engages in the recesses 66, 67 of adjacent upper clamping jaws 54. Between the individual jaws 54, 55 there is a small space, seen in plan view. Thereby, the upper jaws 54 can be adjusted in a manner to be described below down between the lower jaws 55 properly and without risk of contact.

The lower jaws 55 project transversely from a foot 71 (FIG. 14) which connects the jaws 55 with a lifting cylinder 72. With the lifting cylinders 72 can be the lower jaws 55 in Lowering still to be described, if, as with reference to FIG. 7 to 11 has been explained, the woods 3 after the transverse profiling the feed unit 15 are passed. The lifting cylinder 72 are stored on the carrier 47.

The rake-shaped carrier 62 has horizontal, spaced from each other lying fingers 73 (Figures 4 and 14), between which the rod-shaped Carrier 59 for the upper jaws 54 and the feet 71 protrude for the lower jaws 55. The carrier 62 is with with Spaced apart upright supports 74 provided on which the compression springs 63 of the stops 31 are supported by one end are. The rake-shaped carrier 62 can be horizontal in Arrow direction 75 are adjusted on the support member 52 of the carrier 47, to the position of the stops 46 to the cross-sectional shape of the 3 to be clamped wood adapt. The intended Drive is not shown. The adjustment of the rake-shaped Carrier 62 can be done manually; however, it will be advantageous controlled adjusted, so that an automatic adjustment of the Stops 46 with respect to the cross-sectional shape of the machining wood 3 is guaranteed.

The feed unit 15 can also two or more side by side lying support 62, which are advantageous in each other independently The described manner are adjustable to several woods in a row to tension, which are processed with different width should.

As has been explained with reference to FIGS. 7 to 11, the woods are 3 from the Querprofiliereinheit 1 not directly the feed unit 15th handed over the Längsprofiliereinheit 2, but with the help of the transfer unit 36. It is in the transfer position (Fig. 9) with respect to arranged the feed unit 15, that the belts 37, 38 of the transfer unit 36 only a small distance from the jaws 54, 55th the feed unit 15 have. This allows the woods 3 easily from the transfer unit 36 in the feed unit 15 transport. To ensure a trouble-free and optimal transfer of wood 3 to reach before the delivery of the woods, the lower Jaws 55 slightly lowered so far that the support side 68 of the lower jaws 55 below the support level of the lower Bandes 38 of the transfer unit 36 is located. This can do that Wood 3 easily between the two jaws 54, 55 of the Feed unit 15 are transported.

The stops 46 are by appropriate displacement of the rake-shaped carrier 62 in the direction of displacement 75 before the transfer the woods 3 set in the necessary position. The upper ones Jaws 54 are slightly up during delivery adjusted, so that they do not interfere with the transfer process. As soon as the woods 3 arranged distributed over the length of the feed unit Abut stops 46, the upper and the lower Clamps 54, 55 moved together by the corresponding Lifting cylinder 56, 72 are operated. This will be the Woods 3 optimally between the jaws 54, 55 of the feed unit 15 clamped. The clamping is done so that through the Längsprofilierwerkzeuge 18 to be machined longitudinal side of the woods 3 exposed, so that this longitudinal side without obstruction by the Clamping jaws 54, 55 can be processed. During longitudinal profiling The feed unit 15 along the guide rails 50, 51 relocated reliably. Since the guide elements 49 on the Length of the carrier 47 arranged distributed and also in two with sufficient distance stacked horizontal Rows are fixed, the carrier 47 can flawlessly and without danger of tilting. This is a very accurate Processing of the woods 3 guaranteed.

The feed unit 15 forms not only the transport device for the woods in the Längsprofiliereinheit 2, but at the same time the clamping device. This will make the high precision machining of the Woods 3 optimally ensured during the Längsprofiliervorganges.

As shown in FIG. 14, the long side of the woods 3 to be processed stands sufficiently far beyond the jaws 54, 55 of the feed unit in front. As a result, on this longitudinal side the required processing be made. Fig. 5 shows that on this longitudinal side of the wood 3, for example, two holes 76 in the longitudinal side and two holes 76 in the top of the wood 3 with the drilling units 16 have been attached. The drive of the feed unit 15 is designed as a CNC axis, so that the tensioned wood 3 can be moved exactly in the position for drilling. By doing Area where the two holes 76 in the top of the wood 3 is the appropriate upper jaw 54 of the feed unit 15 has been lowered. This is the wood 3 at this point free, so that with the appropriate drilling unit 16 the holes can be attached. As the drive of the Feed unit 15 is designed as a CNC axis, the corresponding Jaws 54, which in the further processing of the Wood 3 in Längsprofiliereinheit 2 could disturb, before handing over the woods 3 in the feed unit under the support level 68th the lower jaws 55 are lowered by the corresponding Lifting cylinder 56 is actuated. The in the feed unit 15th clamped wood 3 can then be exactly relative to the machine-fixed Drilling units 16 drive, the locational exactly the necessary Install holes.

The transport unit 77 will be described with reference to FIGS. 12 and 13, with the woods 3 in the manner described from the transfer unit 36 are pushed into the feed unit 15.

The transport unit 77 has a plate-shaped carrier 78, the its the wood 3 side facing with spaced apart Andruckbacken 79 has. The Andruckbacken 79 extend about the height of the beam 78 and the wood 3. The front sides the Andruckbacken 79 are rounded, so that they only linear rest against the wood 3. The transport unit 77 is provided with a (not shown) drive, preferably with lifting cylinders, in the direction adjusted to the stops 46 in the feed unit 15.

The transport unit 77 is located in the transfer area of the woods 3 from the transverse to Längsprofiliereinheit and is part of Transfer unit 36. The transport unit 77 is then actuated when the woods 3 between the open jaws 54, 55 of the feed unit 15 are pushed. The jaws 54, 55 remain open until the wood 3 by means of the transport unit 77 at the attacks 46 has been brought to bear. Then the Clamping jaws 54, 55 of the feed unit 15 is actuated so that they Clamp wood 3. Only when this clamping process is completed, the transport unit 77 is returned to its original position.

With the transport unit 77 can be slightly curved over its length Woods 3 can also be pushed straight to even those woods despite their longitudinal curvature can work properly. Will that be curved timber 3 in the manner described with the transport unit 67 brought to the stops 46 of the feed unit 15 to the plant, becomes by further pressurization the transport unit 77 moves toward the stops 46. Here is the Wood 3 adjacent to the stops 46 straightened (Fig. 13), so that it rests with its one longitudinal side of the stops 46. The transport unit 77 remains in its printing position according to FIG. 13 until the jaws 54, 55 of the feed unit 15 the straight pressed wood 3 clamped. The elasticity of the Jaws 54, 55 is so high that the wood 3 after returning the transport unit 77 in the feed unit 15 in his straight pressed situation remains.

FIGS. 2 and 15 show the machine with two longitudinal profiler units, which is thus equipped with two feed units 15. As 15 shows, these two feed units 15 are the same, However, arranged mirror images of each other. Are the woods 3 in the manner described in the right in Fig. 2 feed unit 15 clamped, then the woods are with her to the drilling units 16 and past the Längsprofilierwerkzeugen 18, with where the right in the direction of transport 21 long side of the woods 3 edited becomes. The left in Fig. 2 feed unit 15 is located in a transfer area 80 (Fig. 2), which is in the area between the Double drilling units 16 and longitudinal profiling tools 18 is provided. The two feed units 15 are so to each other arranged, seen in the direction of transport 21 (Fig. 15), that their jaws 54, 55 only a very small distance from each other to have. The woods 3 are clamped in the one feed unit 15, that they are sufficiently over in the manner described the jaws 54, 55 protrude. This supernatant is so big that the other feed unit 15 with its clamping jaws 54, 55th can clamp the wood in this area.

Fig. 15 shows the machine from the outlet side. The right feed unit 15 has the wood 3 so on the appropriate tools has passed in the Längsprofiliereinheit 2 that in Fig. 15, the left longitudinal side of the timber 3 has been profiled, in the direction of passage of the wood 3 through the machine is the right long side. When this feed unit 15 moves into the transfer area 80, are the jaws 54, 55 of FIG. 15 left feed unit 15 so wide that the wood 3 with its protruding Area unhindered between the jaws of this feed unit 15 can retract. The rake-shaped carrier 62 with the Stops 46 is moved in the direction of the wood 3, that the Stops 46 come to him to the plant. Subsequently, the Jaws 54, 55 of this feed unit 15 closed and so that the wood 3 is stretched at the protruding area. Subsequently can the jaws 54, 55 of FIG. 15 right feed unit 15 are opened, so that this wood 3 only through the Clamping jaws 54, 55 of the left feed unit 15 is stretched. The right feed unit 15 of FIG. 15 can then go back, from the Querprofiliereinheit 1 in the manner described the to take over next woods 3. The left in Fig. 15 feed unit 15 now performs the tool 3 to the appropriate tools so past that in Fig. 15 right long side of the wood. 3 is profiled, in the direction of passage of the timber 3, the left longitudinal side is.

The two feed units 15 are at opposite ends Pages in the manner described on a frame part 81st with the guide rails 50, 51 proceed.

In another, not shown embodiment, the machine with one above the other arranged in pairs feed units 15 provided, of which the upper feed units to a horizontal Axis mirrored above the lower feed units 15 are arranged. Through such training, the Performance of the machine increases, since a feed unit already in the each transfer position can go back while the second Feed unit, the wood 3 at the respective Längsprofiliereinheit passes.

The longitudinal feed of the woods 3 in the Längsprofiliereinheit 2 means the feed unit 15 allows accurate tracking, surveying and positioning the timbers over the axles. Thereby are ensures high manufacturing precision and high process reliability. The milling and drilling operations are carried out in one machine, so that a parts complete machining on the machine possible is. Since the woods 3 are transported through the transverse and the longitudinal profile unit 1, 2 are always clamped and not on Table surfaces or stops slip, the corresponding page treated the woods gently. Also, no chip rolling occurs on. With the feed unit 15 and with the clamping device 4 it is possible, the woods 3 several times to the appropriate tools 11, 18 drive by to different processing on the wood 3 make. In this case, the respective spindles 10, 17 respectively radially and / or axially adjusted to those for the different Machining necessary cutting blades engage can.

Since the woods 3 throughout the processing and also during the various handover procedures are firmly established, the position of the woods 3 can be determined exactly at any time. This makes it possible to use the woods 3 with this machine to process high production precision. In particular, it can in the manner described in the Längsprofiliereinheit 2 the Drilling and / or milling with the machine-fixed drilling units 16 are attached, since the woods 3 with the feed units 15 are positioned accurately relative to the drilling units 16 can.

Since the drive of the feed unit 15 is designed as a CNC axis, Dives can also be made on wood 3. this includes are profilings that are not understood over the whole Length of the wood 3 extend. Due to the high positioning accuracy The tools can be exactly in the wood retracted and driven out of it.

Since the feed unit 15 is moved CNC-controlled and also the tools 18 and their spindles 17 CNC-controlled transversely to the direction of travel the feed units 15 are movable, can by Interpolation from these two perpendicular movements the spindle 17 and the feed unit 15 any Contour of the long side of the woods can be achieved. That's how it works the wood Stichbögen, wavy lines and the like without problems produce.

With the clamping device 4 and the feed unit 15 can even very short woods 3 are processed reliably. Thereby eliminates elaborate special production.

The machine parts are constructed as modules, so that the machines can be put together in different ways. So is the construction of the machine regardless of its length, as with appropriate Machine lengths a corresponding number of modules is compiled. The modules can be assembled to the machine be that they work as a legal or link unit can.

The magazine 24 (Fig. 1) may be formed so that from him the to be processed wood 3 automatically removed and in the Machine entered and returned after editing become. The machine can operate without operator, because a high Process reliability is guaranteed.

Since the woods 3 are not adjacent to a stop by the machine be transported, but each by means of the clamping device 4 and the feed unit 15 are clamped, is a variable Chip removal on wood 3 without any problems via the spindle position controllable. This results in a high flexibility and optimal Rohholzausnutzung.

The spindle guides are advantageously made of polymer concrete, which achieves optimal vibration decoupling of the spindles becomes.

The spindles may, for example, have a length of 700 mm and have a variable stroke of 650 mm. This results a complete freedom in spindle occupation, i. the choice of tools to be attached to the spindles. This is a simple one Design of woodworking possible.

Since all wood and tool movements on the controller from electrical axes, results in a high precision, a great variability as well as a considerable simplification of the project planning. Because of the controlled axes at any time an accurate Knowledge of the location of the timber 3 inside the machine ensured can be used in conventional window machines Photoelectric sensors are eliminated, which are often significant sources of error known window machines are. Is the machine as a continuous system formed in accordance with FIG. 2, mechanizations of Machine omitted, such as return devices, pivoting devices and the same. For the positioning of the woods 3 is a Length stop not required, resulting in very small length tolerances the processed wood 3 result. As the woods at least controlled in the processing phases via the electronic axes limit switches can be used in the feed of the machine for Tracking the wood accounts. Due to the regular clock cycle The machine is a buffer or magazine and their management is not necessary.

Since the woods 3 in the transverse and in the longitudinal profiling each transported with the clamping device 4 and the feed unit 15 are, table tops are for supporting and supporting the woods not necessary anymore. The related problems in terms of wear and breakage in the field of Spindles are eliminated. Also, the conventional ones Window machines existing right stops omitted, the Problems with regard to wear, milling and adjustment work, the guide break in the field of spindles as well prepared for optimal chip detection.

The feed units used in conventional window machines in the form of feed rollers and the associated Problems are eliminated. Feed rollers can wear out and pollute, causing the transport of the woods is affected by the window machine. In addition, must the feed rollers are adjusted. Due to the feed bar the tools on the window machine are difficult accessible. The position of the woods in the machine must be at a such feed unit to be monitored by limit switches, which can lead to problems.

Turn the woods into a window or door frame or wing assembled, this frame or wing will follow transported through the window machine and here a milling performed. In this Umfräsarbeiten is the feed bar hindrance. For the milling of small frames or wings is an additional Milling trolley required. In particular, such Umfräswagen not usable for studio windows where the frame parts partially connect at angles not equal to 90 ° to each other.

Such problems do not occur in the described machine, because the feed unit 15 are also used when milling can. As shown in Fig. 16, it is machined from those machined in the machine Wooden 3 composite frames 82 on the outside of the Frame parts machined, in particular milled. The frame 82 becomes with its one frame part 3 to the stops 46 of the feed unit 15 applied and in the manner described with the jaws 54, 55 excited. Since of the clamped frame part 3 from perpendicular to the other frame parts stick out, those are Jaws 54, in the range of these transversely projecting frame parts lie before clamping the frame 82 under the support plane 68 of the lower jaws 55 (Fig. 14) lowered. The lowering the corresponding jaws 54 is programmatically depending on the frame 82 to be milled. Thus For example, the frame 82 can be easily inserted into the feed unit 15 and be curious. The lowered jaws 54 take the lying in their displacement stops 46 against the force the compression springs 63 with. As shown in FIG. 6, the clamping jaws 54 in the region of the main body 64 so wide that they two at the same time Detect stops 46 and press down.

Fig. 16 shows a sash 82 with a rung 83. With the Feed unit 15 can also be two or more adjacent Frame 82 are clamped to mill the outsides. The number of frames 82 to be clamped simultaneously depending on the length of the feed unit 15 and the length or Width of the frame.

With the feed unit 15, the wood 3 in its transport held by the machine, especially in the field of respective tools. So can a left proof, as with conventional Window machines is provided, omitted. By the fixed clamping in all feed or clamping devices arise on the wood 3 no impressions, grooves and the like.

Based on the drawings, the machine is described as an angle machine have been the cross and the longitudinal Sprofiliereinheit 1, 2 has, which are at right angles to each other. The described feed unit 15 may also be provided in a machine that does not have a Querprofiliereinheit with which the woods 3 thus only be processed on at least one longitudinal side.

The machine according to FIGS. 17a to 17d is mainly used for production used by furniture parts and has no Querprofiliereinheit on. The woods 3 are either by hand or through a magazine placed on the feed unit 15 and with the upper and lower Clamping jaws 54, 55 clamped. The woods 3 are here with its one end face on a machine-fixed stop 85 for Attachment brought to get a length reference. So that Woods on their abutting the stop 85 end face 86 in still too descriptive way can be edited, stand the woods via the jaws 54, 55 in the transport direction. As soon as the Timbers 3 aligned with the longitudinal stop 85 and with the clamping jaws 54, 55 are tightened, the stopper 85 is from its stop position removed and the feed unit 15 in the transport direction 21 transported.

When transported in the transport direction 21 reach the woods 3 first in the working area of the tool 87, with a corresponding Machining made on the front side 86 of the woods 3 becomes. The tool 87 may be a tool magazine 88 in which are cutters, drills, angle units, saws etc. may be arranged. The tool 87 sits on a transverse to the transport direction 21 movable carriage 89, along a Guide 90 perpendicular to the transport direction 21 in the transport direction 91 between the tool magazine 88 and the processing station can be moved. After machining the end face 86 is the wood 3 with the feed unit 15 in the transport direction 21 on transported to a subsequent tool 92. It is also sitting on a carriage 93 which is perpendicular to the transport direction 21 between another tool magazine 94 and its processing station along a guide 95 can be moved. The Tool magazine 94 may be the same design as the tool magazine 88 and different tools for longitudinal processing, Cross-cutting, for drilling or sawing wood 3 contain. With the feed unit 15, the woods 3 are rotating at Tool 92 passed, which in the transport direction 21st right long side of the woods 3 edited.

If the longitudinal processing of the wood 3 is completed, the feed unit 15 retracted against the transport direction 21 to the operator. After loosening the clamping device he takes the wood 3 and it turns around its transverse axis by 180 ° (Fig. 17b). This turned Wood 3 is again between the jaws 54, 55 of the feed unit 15 clamped. The wood 3 is after the turning process with its machined end face 86 on the machine-fixed Stop 85 applied, which in this case from that shown in Fig. 17a Situation in the position shown in FIG. 17b can be adjusted. It but it is also possible to provide a second machine-fixed stop, to align the partially worked wood 3. To the clamping, the feed unit 15 is again in the transport direction 21 proceed. With the tool 87 is now the other Front side 96 of the wood 3 (Fig. 17c) processed. Thus a problem-free Editing this front is possible, the wood 3 is so between the jaws 54, 55 clamped that the wood 3 is sufficient protrudes far in the transport direction 21 via the feed unit 15. After machining the end face 96, the tool 87 moved back transversely to the transport direction 21. The feed unit 15 is then moved further in the transport direction 21 and the wood 3rd passed the tool 92, with the now the other long side of the wood 3 is processed. As soon as the longitudinal processing of the Wood 3 is completed, the feed unit 15 is in the starting position moved back (Fig. 17d). The operator can then do that on the two opposite longitudinal sides and on the two end faces 86, 96 machined wood 3 of the feed unit 15 (Fig. 17d).

In the described method, the wood 3 twice through the Machine moved by means of the feed unit 15, wherein at each Passage processed one end face and one longitudinal side of the wood 3 becomes.

Fig. 18 shows an embodiment in which the wood 3 in a single Passage through the machine on both sides and on both end faces is processed. The wood to be worked becomes either manually by an operator or via a magazine abandoned on the clamping unit of the feed unit 15. The wood is clamped between the jaws 54, 55 of the feed unit. The front in the transport direction 21 end of the wood 3 is sufficiently far over the feed unit 15 before, so that with the Tool 87, the end face 86 of the wood 3 can be edited. After this front side machining, the tool 87 by means of Schlittens 89 retracted and the feed unit 15 further in Transport direction 21 moves. The wood 3 then enters the area of the tool 92, with the right in the direction of transport 21 Long side of the wood 3 is processed. According to the previous one Embodiment, the wood 3 is sufficiently far over the jaws 54, 55 before, so that this longitudinal side properly can be edited.

In the transport direction 21 behind the tool 92, the wood 3 a passed second feed unit 15, which on the opposite Side of the guide 97 for the two feed units 15 is arranged in mirror image. The wood 3 is so to the further feed unit Pass 15 that wood 3 with his counter Transport direction 21 lying end over this feed unit 15th protrudes. The further feed unit 15 has the jaws 54, 55, with which the wood is clamped at the top and bottom becomes. The wood 3 is in the transfer with the jaws 54, 55 the further feed unit 15 tightened as long as the jaws 54, 55 of the other feed unit 15, the wood 3 is still stretched In this way, a flawless delivery of the Holzes 3 ensures, as it always strained at this handover is held.

After transfer, the further feed unit 15 in the transport direction 21 moved on. With a tool 98, which by means of a Carriage 99 is transverse to the transport direction 21 is adjustable, the in Transport direction 21 left longitudinal side of the wood 3 edited. With the following in the direction of transport 21 tool 100, the is also mounted on a carriage 101, then the in the transport direction 21 rear end face 96 of the wood. 3 processed.

After passing through the machine, the wood is 3 at both End faces 86, 96 and processed on the right and left longitudinal side. The wood 3 is then removed from the feed unit 15 and perpendicular to the transport direction 21 after releasing the clamping device continued.

With this machine, the woods are 3 using two feed units 15, the same advantageous and mirror image of each other are arranged, at their two opposite Long sides edited. This machine works very productively. As described with reference to the embodiments of FIGS. 1 to 16 can in the other embodiments in the top and bottom of the woods 3 also made holes become.

As in the previous embodiment, the machine has one each Magazine 88, 94 for the tools 86, 92. This way is always an aggregate in use, so that the machine high productivity or short lead times. It is also possible only one aggregate for longitudinal and transverse machining. But then you have to a non-productive time for changing tools for the transverse and the longitudinal processing are accepted.

The machine according to FIGS. 19a to 19e has the same as the previous one Embodiment two feed units 15, which on each other opposite sides of the guide 97 mirror images of each other are arranged. Both feed units 15 are advantageous the same education. The operator tensions the wood 3 to be processed in the feed unit 15, as explained with reference to FIG. 17 is. The feed unit 15 is then in the transport direction 21 past the tools 87, 92, with which in the described manner in the transport direction 21 front end side 86 and processed in the transport direction right long side of the wood 3 become.

In the transport direction behind the tool 92 is the second feed unit 15, to which the wood 3 is transferred, as based on Fig. 18 has been explained in detail (Fig. 19c). With this second Feed unit 15, the wood 3 is opposite to the transport direction 21 along the guide 97 retracted. This is the Wood 3 at its other end face 96 and at the transport direction this second feed unit 15 right longitudinal side with the Tools 92, 87 edited. After the two-way passage through the machine, the wood is thus on both its long sides and machined on its two end faces 86, 96. With the second Feed unit 15, the wood 3 after the second passage in Transport direction 21 again moved back (Fig. 19e), wherein the both tools 87, 92 are moved back. Then that will be done processed wood of the second feed unit 15 taken. Meanwhile the operator can see the next wood to be machined 3 in clamp the first feed unit 15.

FIGS. 20 and 21 show the possibility in the feed unit 15 securely clamp wide, flat workpieces 3 with suction clamps to be able to. For this purpose, the upper jaws 54 are down adjusted (Fig. 20), so that all the jaws 54, 55 on the same Height are.

The jaws 54 are on their support side with frame seals 102 provided (Fig. 20), in the lowered position of the jaws survive over the lower jaws 55. Furthermore are the jaws 54, each with at least one passage opening 103 provided. The sheet-like wood 3 (FIG. 21) is placed on the Jaws 54, 55 launched, with the protruding frame seals 102 clean against the support side of the wood 3. About the openings 103 then negative pressure is generated, through which the flat wood 3 firmly against the jaws 54, 55 pulled and reliable is held. The jaws 54 thus form Saugspanner, connected in a known manner to a suction system are.

In the described embodiments, the upper and lower Clamping jaws 54, 55 each arranged in a gap to each other. But it is also possible, not all jaws 54, 55 on gap to arrange, but only a part of these jaws. So can For example, the first upper and lower jaws 54, 55th exactly above each other, while only the subsequent jaws 54, 55 lie on the gap. Such training is that Wood 3 in the area of its front for the cross-processing safely and sturdy. Even shorter woods 3 can be safe Clamp.
