Definitions

  • the invention relates to a device for producing a square timber by cutting a sequence of side boards from opposite sides of a log in a number of immediately successive cutting processes in the longitudinal direction of the trunk with a feeding device which receives the log and moves in the longitudinal direction, and a processing device in which on both sides of the log to be processed, several knives are staggered one behind the other to form a cutting group that can be driven for a common oscillating movement, each knife being preceded by a pressure bar and between each knife and the pressure bar of the subsequent knife and, if appropriate, in front of the first pressure bar and behind the last knife of each cutting group, a guide bar touching the processing surface of the log is provided, which is connected to the respective cutting group.
  • German patent 2 514 901 and the associated additional patent 2 751 238 are the subject of cutting in longitudinal direction in several immediately successive cutting operations without cutting into boards.
  • the additionally interposed guide bars have a substantially larger contact surface than the pressure bars because they are not supposed to exert a high local pressure, but rather guide the model in a desired orientation again before the next firing process, if this should show a tendency to move sideways, for example due to different wood hardness on both sides of the trunk. It had turned out that without such additional guidance, an acceptable surface quality of the cut boards could usually not be achieved.
  • the guide strips exert a smoothing effect on the outer wooden surface, if one also takes into account that these guide strips, due to their fixed attachment to the swinging knife frame, not only constantly exert a relative movement in the direction of advance of the wood to the wooden surface, but also a circular motion or oscillating movement that is at least at an angle to the feed direction.
  • the two lateral knife groups are fixed to a certain lateral distance from the longitudinal axis of the feed path in accordance with the trunk diameter to be processed or the thickness of the squared timber ultimately to be produced. If it is mentioned in DE-PS-2 751 238 that the guide strips exert pressure on the log from both sides, this pressure is essentially generated by the reaction of the elastic wood material itself. This is obvious when looking at the knife and guide bar assembly in the accompanying drawing.
  • the guide strips upstream of the first knives were set so firmly in the known procedure that their lateral spacing corresponded to the dimension of the trunk, which was usually flattened laterally, whereby a guide under certain pressure could be achieved by a slight narrowing compared to the trunk diameter.
  • the pressure effect of the other guide strips was determined on the one hand by the gradation of their setting within the knife frame and by the setting of the knives. If a certain knife takes more wood than intended, the pressure on the following guide bar can be reduced. On the other hand, the wood has a certain springback effect, so that with the correct setting of the knife and the subsequent guide bar, nevertheless There is pressure between the wood and the two opposite guide rails.
  • the conditions can still be relatively undefined even when using the additional guide strips, which has an adverse effect on the quality of the products obtained. It should also be noted that different or changing pressure of the pressure and guide strips also affects their frictional losses on the wooden surface and thus the energy consumption by the oscillating drives of the knife groups and overall the energy consumption of the feed drive.
  • the invention is therefore based on the object of making the conditions within the device more constant and influenceable in the interest of improving the product quality obtained and a more cost-effective mode of operation by means of lower energy consumption.
  • one of the cutting groups can be fixed at a certain distance from the longitudinal axis of the feed device and the opposite cutting group can be pressed with a defined pressure against the trunk being processed.
  • the stroke required for such pressing only needs to be relatively small, which is why the two opposing cutting groups for their symmetrical basic setting, depending on the thickness of the wood to be processed, are expediently both arranged on cuts which can be displaced transversely to the transport direction, but which are then used for processing a specific one Wood thickness can be fixed.
  • the pressing group can then advantageously be displaced in the transverse direction in addition to the associated slide and relative to it for the pressing stroke, the pressing drive having to engage the associated slide.
  • Hydraulic or pneumatic cylinders can be provided as the pressure drive, but electromotive and other drives are equally possible.
  • the return movement of the contact group which can be pressed on is expediently limited by stops on the associated slide, as a result of which the movement stroke can be kept to the merely necessary small extent.
  • These guide surfaces are set to a fixed distance required for a specific trunk diameter by the symmetrical adjustment movement of the slides carrying the cutting groups.
  • milling heads are therefore advantageously connected upstream of the guide surfaces. These milling heads are adjusted in coordination with the guide surfaces so that the thickness of the flattened trunk essentially corresponds to the set distance between the guide surfaces. It is not appropriate to design the device in such a way that the first Guide strips of the pressing-on cutting group area still come into contact with uneven trunk surfaces. Under such conditions, the subsequent knife groups would not work evenly.
  • the part of the device shown in plan view in FIG. 1 consists of a trunk feed device 1 with a series of paired, symmetrically pivotable driven feed rollers 2 and the downstream processing device 3.
  • This has a base frame 4, which is provided with the (not shown) oscillating drive for the Cutting groups can be provided.
  • the base frame 4 contains transverse guides 5, on which the slide 6 can be moved towards or away from one another in a guided manner parallel to the longitudinal axis of the log feed device by means of a spindle drive 7.
  • Each of these slides 6 is provided in its entrance area adjoining the trunk intake device 1 with a milling cutter 8 which is rotatably driven about a vertical axis and which serves to flatten a lateral surface of the tree trunk 9 being processed.
  • the milling cutters 8 are followed by guide surfaces 10 which are in contact with the flattened sides of the tree trunk 9. When processing squared timber or logs already flattened on the side, the milling cutters 8 can be moved back relative to the slide 6 out of engagement with the log or model 9 being processed.
  • the guide surfaces 10 are generally adjustable with respect to the slide 6, they are adjusted to a fixed position on the slide 6 in cooperation with the depth of penetration of the milling cutters 8.
  • a light barrier 11 follows the guide surfaces 10, the receiver or transmitter of which is mounted on one of the slides 6. This light barrier 11 signals whether there is a trunk in the entry area of the processing device 3.
  • the staggered cutting groups are now arranged as essential elements of the processing device behind the light barrier 11. While the cutting group 12 is firmly attached to the associated carriage 6, the cutting group 13 shown in the drawing below is mounted on a separate frame 14 which can be displaced in the transverse direction to the direction of advance of the wood 9 relative to the associated carriage 6 by a limited stroke. In its movement relative to the carriage 6, the frame 14 is also guided in parallel by means (not shown) so that it cannot tilt during its movement.
  • the frame 14 is connected to the associated slide 6 via a hydraulic actuator 15, for example, the cylinder 16 of which is attached to the slide 6 and the piston rod 17 is articulated on the frame 14.
  • a hydraulic actuator 15 for example, the cylinder 16 of which is attached to the slide 6 and the piston rod 17 is articulated on the frame 14.
  • stops 18 are provided to limit the return stroke between frame 14 and slide 6.
  • Each of the cutting groups 12, 13 consists of a series of knife units 19, each of which has a knife 21 clamped in a knife holder 20.
  • the knife carriers 20 are each provided with pressure strips 22 and guide strips 23, as is described in detail in DE-PS-2 751 238. Correspondingly different arrangements are provided only in the area of the first and last knife.
  • pull-out and straightening systems 25 are arranged, which on the one hand remove the boards from the work area and on the other hand undo the curvature of the boards which has occurred as a result of the cutting process.
  • the remaining squared timber 26 is removed by means of a pull-out device 27 which is only indicated schematically.
  • the carriages 6 When the device is in operation, the carriages 6 are moved together with the milling cutters 8 and the guide surfaces 10 to a specific distance corresponding to the trunk diameter to be processed and are locked in this position.
  • the actuator 15 of the frame 14 is retracted so that the frame 14 bears against the stops 18 of the carriage 6. If a log 9 occurs after flattening its two sides through the milling cutters 8 between the guide surfaces 10 and into the light barrier 11, the latter signals the presence of wood and causes the hydraulic actuator 15 to press the cutting group 13 arranged in the frame 14 against the model.
  • the cutting group 13 can remain in its preset position, so that wood is continuous, i.e. can be edited without space.
  • the frame 14 is moved back to the stops 18 by means of an actuator 15.
  • the pressure bars 22, which have a small pressure area, are generally set in this way are that they protrude somewhat towards the longitudinal axis of the device in relation to the larger guide strips 23. This ensures that the pressure strips 22 always penetrate into the wood with a certain depth of penetration and also a fairly precisely defined contact pressure in front of the subsequent knife and thus ensure constant cutting conditions.
  • the guide strips 23 enclose the trunk being processed between them and exert a relatively constant and selectable pressure on the wood from both sides. It has been shown that a product of substantially improved quality can be obtained through this measure.
  • FIG. 2 shows a device with two actuators 15, which can be subjected to different forces and whose cylinders 16 are pivotably attached to the slide 6. In order to distribute the contact pressure over the entire length of the cutting group, this is articulated by means of a link 29 on the carriage 6 so as to be pivotable about a vertical axis.
