Definitions

  • the invention relates to a device for cutting logs into Wood products and one for this suitable milling head.
  • a generic device is for example in DE-C-29 28 949 described.
  • This device has i.a. Milling heads with cleaver, the cutting edges of which produce a cylinder jacket when rotating and thus run parallel to the axis of rotation of the head.
  • the milling heads are for that intended to mill out tree-corner areas from a tree trunk, which already delimit side boards at the trunk, which are then by means of be cut with a saw.
  • step milling cutters can also be used as milling heads with which two parallel corner folds are milled out simultaneously which then limit two side boards in pairs, which are cut off using saws.
  • the dimensions of the second corner are in Relationship to the first corner by the dimensions of the tool, d. H. by the dimensions of its chopping knife ring of smaller diameter certainly.
  • the width and thickness of the narrower, outside Side boards regardless of the limit of the wider, inner Side board can be changed, so this is only with two separate, successive milling heads possible, each with a cleaver wear and in their immersion depth in the workpiece independently are adjustable.
  • the invention has for its object to provide a milling head for a device designated type to create that for the narrow-sided limitation of side boards to be separated on one side of a tree trunk two such has mirror-image milling heads, each of which is adjustable so that Thickness and width of the outer side board to be separated regardless of the dimensions of the inner side board are adjustable.
  • the milling heads of a pair essentially stand in the vertical direction mirror image of each other and can therefore from a common, vertical drive shaft.
  • a tree trunk to be processed moves horizontally through the device so that the mutual distance of the milling heads of a pair the width in vertical Direction of at least the wider of the two side boards to be bounded certainly.
  • the immersion depth of the milling head pair in the horizontal direction determines the common thickness of both side boards. This immersion depth is generally the entire, both milling heads and their drive Tool unit adjustable in the horizontal direction.
  • the drive shaft for a pair of milling heads can be the mutual vertical distance adjust the milling heads by moving them on the shaft.
  • this Position given once is the ratio in which the thickness of the whole side goods to be separated to the thickness of the inner and outer Side board is divided by the difference in the rotating diameter the chopping knife ring of larger diameter and the chopping knife ring smaller diameter determined. Since the difference is important here it is basically possible to either the rotational diameter of the Chopping knife ring of larger diameter in relation to Rotation diameter of the chopping knife ring smaller diameter change or vice versa.
  • Is the radius for a change in diameter of the chopping knife ring of larger diameter must, of course correspondingly the immersion depth of the entire tool in the horizontal direction be changed in order to remain at the same side fabric thickness.
  • the amount by which the outer board is narrower on each side than the inner side board, is determined by the effective width of the cutting edges of the cleaver smaller diameter determined. This effective width is essentially the projection that the cleaver of the wreath has a smaller diameter in the vertical direction over the vertical extension of the cleaver Have wreath of larger diameter on one side.
  • This Overhang becomes relative to a variation in the width of the outer side board to the inner side board according to the invention held variable in that the Cleaver of the wreath of smaller diameter in different Cover with the chopping knives of the wreath of larger diameter are feasible, being more effective through the area of this coverage Lose width because the cleaver of the wreath is in the overlap area larger diameter have a larger working radius, so that the knife of the wreath of smaller diameter does not come into effect here.
  • the adjustability of the cleaver of a knife ring individually or overall compared to each other's knife ring can run different ways.
  • a possible Adjustability exists by means of displaceability of the knives or their Knife carriers along complementary, linear profiles and by mutual Clamping using, for example, clamping screws in a certain one Position.
  • Such an embodiment is suitable for a knife adjustment of Hand.
  • the carrier body of the milling head it is also possible in the carrier body of the milling head to provide remote actuating means, such as motorized Eccentric, spindle drives or other gears, but also hydraulic drives. Methods of supplying the required energy and the required Signals via rotary unions on the drive shafts are in the state of the Technology available.
  • the cleaver of the Wreath of smaller diameter in a separate carrier element be arranged, which as a whole more or less in the carrier body is designed to be immersible so as to ensure the axial projection of the cutting edges of the Knife ring of smaller diameter over the ends of the cutting edges of the Knife ring larger diameter can change together.
  • a such an embodiment would be, for example, for a hydraulic adjustment drive suitable.
  • Both adjustments are smaller in the chopping knives of the wreath Diameter provided, it is advantageous as a finishing tool
  • To provide finishing knives on the knife carriers for the cleaver of the Wreath of smaller diameter are provided because they are in such a Apply a radial adjustment of this cleaver with.
  • This Finishing knives are additional knives, the cutting edge of which is essentially in a radial plane, i.e. in a plane that is perpendicular to the Knife cutting extends the cleaver.
  • the number of chopping knives to produce recyclable wood chips in a knife ring preferably kept relatively small and exists generally only from two cleavers. This minimum number is alone for reasons of rotational symmetry and mass balance.
  • a device for disassembly The cross-section of tree trunks in wood products is a tree trunk 2 shown, which is already flattened on four sides. From the rectangular Cross section can be derived that at the top and bottom of the Tribe already side boards in the same way and then limited were then separated as follows for the left and right side of the tree trunk 2 is explained.
  • the tree trunk 2 is through a support member 4 is supported and moves in a direction perpendicular to Drawing plane through the device.
  • the two milling heads 6 of a pair are each one common shaft 8 rotatably driven, the axis of which each Axis of rotation 10 of a milling head 6.
  • the waves 8 are with (not shown) provided rotary drives.
  • the relative distance of a pair of milling heads 6 to each other in the vertical direction is by opposing Moving the milling heads 6 on the shaft 8 possible.
  • the means to Adjust the milling heads in the vertical direction and to lock the Milling heads in a certain distance setting are not in detail shown.
  • Each milling head 6 has a ring 12 of chopping knives 14 larger Diameter and a wreath 16 of chopping knives 18 smaller Diameter.
  • the only partially visible cutting edges of all cleaver 14 and 18 essentially run in the illustrated embodiment vertical direction in or parallel to the drawing plane.
  • the cleaver 14 when the log is moving 2 an inner corner 20 of the trunk profile perpendicular to the plane of the drawing and mill the cleaver 18 out of an outer corner 22. It is still recognizable that the size and location of the inner corners 20 by the immersion depth the milling heads 6 as a whole in the vertical and horizontal directions in the Tree trunk is determined.
  • the formation of the outer corners 22 depends on the other hand, of the dimensions and position of the cleaver 18 of the knife ring 16 smaller diameters in relation to the location and dimensions the cleaver 14 of the knife ring 12 larger diameter.
  • the cleaver 18 of the knife ring 16 are smaller in diameter itself adjustable relative to the milling heads 6. More details are explained using the exemplary embodiment of a milling head according to FIG. 2.
  • the cutter head 6 shown in perspective in FIG. 2 has one Carrier body 24 of substantially hollow cylindrical shape, in the Scope at diametrically opposite points the cleaver 14 des Cleaver of larger diameter are embedded.
  • the cleaver 14 are in the carrier body 24 by means of a screwed-in knife holder 26 and a counter-screwed pressure plate 28 attached.
  • the lower edge 30 of the carrier body 24 shown in FIG. 2 does not reach in contact with the tree trunk, as easily shown by the bottom Milling heads can be seen in Fig. 1. He can do something to stiffen you have a larger diameter.
  • the wreath of Cleavers of smaller diameter also have two diametrically opposing cleaver 18, but in their circumferential position compared to the chopping knives 14 of the larger diameter ring easily are staggered.
  • the cleaver 18 are by means of pressure plates 32 clamped against knife carrier 34.
  • These knife carriers 34 are in two directions substantially perpendicular to each other, namely on the one hand in axial direction of the milling head and in the substantially radial direction of the Milling head are adjustable.
  • Each knife carrier 34 itself is by means of screws 36 against a knife support 38 clamped, on which he loosened the screws 36 by means of radial T-slot guides movable and in different positions by the Screws 36 can be locked again.
  • the knife supports 38 in turn are not shown in (in the drawing) visible) axial guides within the carrier body 24 arranged.
  • the Lock knife supports 38 in different axial positions. How out Fig. 2 can be seen, the knife 18 immerse in an axial displacement Direction towards the carrier body 24 through openings 44 in the Carrier body so that their protrusion over the top edges of the cleaver 14 of the wreath larger diameter is changeable. With that one The section with which the knives 18 dip into the openings 44 is they not effective. Their effective length is just their overhang Top edge of the cleaver 14 also. This supernatant determines the vertical depth of the outer corners 22 in FIG. 1.
  • finishing knives 48 are finishing knives attached to the outer edge of the knife carrier 34 in a manner that their Cut smaller in the tangential direction of the cleaver Diameter. They serve the same purpose as that Saw blade segments 46. Since the finishing knives 48 on the knife carriers 34 are attached, they carry out all adjustment movements of these knife carriers, so that they always remain in the same relative position to the chopping knives 18 and each finish the horizontal surfaces of the outer corners 22 in FIG. 1 or fine machining.
  • the adjustment of the chopping knife 18 of the small diameter knife ring in the milling head shown in Fig. 2 is done by hand. To run a precise setting it is advisable to briefly remove the milling head from the Take out device and in a correspondingly set teaching place, in which the loosened cleaver 14 then dimensionally accurate in a new position can be braced. An adjustment of the cleaver 18 by suitable automatic adjustment is also possible.
  • the milling head according to the invention makes it possible in a system in which step corners are to be worked out from a tree trunk with half the number of milling head drives or inventory on a large number of differently dimensioned tools to reduce.
