Definitions
- the invention relates to a transport device according to the Preamble of claim 1.
- the applicant for the Feed of beams to be processed by a carpenter more flexible can be pressed onto the beam surface Drag shoe according to the preamble of the main claim for just prefer non-positive driver coupling.
- the drag shoe is dependent on the delivery conditions of the wooden beam with a smooth and dry surface a rubber pad-shaped, smooth but non-slip surface, on the other hand if it is dirty, damp or even icy surface with such a roughly profiled pressure sole from light metal injection molding proves that of their for example obtuse-angled pyramidal knobs in Form of projections triangular in cross section the ice is broken open or the surface is penetrated, but without it on the beam surface beyond temporary slight local pressure phenomena comes to a correct form fit.
- the generic positioning drag shoe has according to De-PS 42 37 048 for the defined longitudinal direction feed of precisely machined on joinery machines Beams have proven their worth in practice because of the wood spared and yet precise in the respective processing station is positioned; but malfunctions in the system can still occur when such a slim bar for horizontal machining in a joinery machine to be clamped in that at random corresponding Location of the protruding laterally over the bar This shoe from a horizontal tensioning device is detected. Because this can lead to irreversible deformations of the workpiece to workpiece or machine breakage come, since the drag shoe is practically immovable is pressed onto the beam surface.
- the arrangement resists the lateral pressure the one accidentally attacking the side of the towing shoe right here Horizontal clamping stamp until the risk of breakage mentioned occurs because the lateral pressure becomes too large; and till then is the actual workpiece itself at this point actually not at all for the upcoming machining process horizontally against the one behind it as an abutment Longitudinal rail clamped.
- the present invention is the task technical problem, in principle as well simply constructed and equally wood friendly even more versatile and yet essential trouble-free working transport device of the generic type Way of creating, in particular in addition across forces acting on the transport direction of the beam are not lead to damage.
- the transport device 11 shown is used for program-controlled Movement 25 of a workpiece, in particular in the form of a (wooden) beam 12, towards it Longitudinal axis 13 between different successive machining positions to be taken.
- a workpiece in particular in the form of a (wooden) beam 12, towards it Longitudinal axis 13 between different successive machining positions to be taken.
- the beam front end 14 by means of at least one Clamping device 16, 16 ′ defined with respect to a machining or tool station 15, fixed around the beam 12 in a predetermined manner e.g. of a swivel-cut saw, one Drilling unit or a milling head on the different predetermined, that is defined in the longitudinal direction of the bar against each other transferred to edit positions.
- the longitudinal movement 25 of the beam 12 takes place on a feed bed 17, which is just a sliding bed, around a track-guided wagon or as shown act a roller conveyor 18 on a machine frame 19 can.
- a feed bed 17 which is just a sliding bed, around a track-guided wagon or as shown act a roller conveyor 18 on a machine frame 19 can.
- the machine frame 19 With regard to the machine frame 19, the tool stations 15 (if necessary with swivel adjustable Tools) and the clamping devices 16,16 'arranged stationary.
- a track 20 for a towing member 21 is trained.
- a towing member 21 On the towing member 21 is a (here with one arm shown) articulated lever 23, which is under not right angle 24 with respect to the beam 12 to this extends.
- a torque can be generated about the pivot axis 26 27 can be brought into effect so that the opposite, free end of the lever 23 with one on it provided drag shoe 28 presses against the beam 12 or take off from it.
- An interchangeable mountable under the drag shoe 28 Sole 35 transmits the pressure from lever 23 to the bar 12 by means of the pressure direction from the level of the sole 35 above, transverse to the transport directions 25 but extending parallel to their plane, in cross section roughly rectangular-triangular, i.e. sawtooth-rib-shaped Knife cutting 36. But their pressure is not so strong that it leads to irreversible incisions the surface of the beam 12 could come.
- Multiple rib cuts 36 are grouped in pairs under the sole 35, that a steep flank (the inclined flank opposite, as can be seen from the cross-sectional view in Fig. 1) on one of the two opposite Ends of the drag shoe 28 or its sole 35 is and thus pointing opposite to the other.
- the driver cutting 36 expediently not always continuously across to the direction of movement 25 from a side edge of the sole 35 to go through to the opposite, but at least to a gap 38 are interrupted.
- a gap 38 per cutting edge 36 is approximately 38 middle and typically measures about a third of the width of the Sole 35 or the length of the cutting edge 36; with wider soles 35 and accordingly longer driver cutting edges 36 can also at least two more gaps each symmetrically middle gap 38 per cutting edge 36 may be provided.
- a such a central interruption 38 offers the advantage of the often not quite prismatic, but somewhat in cross-section convex thinned bars 12 one on the crowned Concentrated attack of cutting edges 36 and this results in an almost only punctiform introduction of force per cutting edge 36 to avoid in the bars 12; because it could because of the resulting higher specific pressure otherwise lead to undesired surface impressions, and it would not be such a clear longitudinal guidance provide how the now along each cutting edge 36 across Feed direction 25 multiple power transmission.
- the towing shoe 28 becomes its along the cutting edges 36 sawtooth-shaped pressure ribs on the wooden surface 30 transversely to the feed direction 25, that is to say transversely to the longitudinal extent of the beam 12 via a roller conveyor 18 somewhat outstanding guide rail 37, shifted until the Beam 12 itself from the horizontal clamping device 16 ' against this longitudinally extending abutment guide rail 37 is pressed.
- This cross shift of the drag shoe 28 along its cutting edges 36 the bar 12 can be seen in its longitudinal positioning no longer influenced, its already achieved positioning not with respect to a processing station 15 changed more.
- the drag shoe 28 in addition a odometer to determine collision-related issues Equip displacements relative to the workpiece (beam 12), by such an unscheduled misalignment at feed 25 to be able to take corrective action into account, like in this respect in their own generic patent specification explained.
