Definitions

  • the invention relates to a press for the frontal pressing of lumber according to the preamble of claim 1.
  • Such presses are known in the art. They often represent the last workstation in a so-called finger-jointing system.
  • a finger-jointing system firstly lumbers are produced, which are provided with finger joints on their front sides and glued.
  • the ultimate goal of such a finger-jointing system is to produce bases or the like of constant length.
  • the finger-jointed lumbers are fed in one strand of a press, then the strand is cut to the desired length and the lumbers are pressed frontally into a beam or the like.
  • a press on a stop and a ram, wherein the ram is zubewegbar to the stop, so that between the stop and ram the frontal compression of the lumber can take place.
  • the length of the bars to be produced may vary from batch to batch, it is known to make the distance between the stop and the press die changeable.
  • the variable distance does not mean here the pressing stroke per cycle, but hereby means that the distance can be greatly changed so that, for example, bars with a length of 4 m can be produced on one and the same machine as well as bars with a length of 6 m.
  • the stop had to be solved by hand, then moved by hand and then be locked again by hand. This means that when a batch change in each case a mechanic is needed and relatively long changeover times arise.
  • FIG. 6 shows that shown in FIG. 5 in a fourth working state
  • FIG. 7 shows that shown in FIG. 6 in a fifth working state
  • this strand is pushed from this first position by the slider 48, which is arranged on the machine frame 10 via pneumatic cylinder 50, in the y-direction to the second position, this movement being perpendicular to the insertion direction of the wood strand.
  • the stop 40 can have a T-shaped cross-section, with the result that the slide 48 is located under the front end. 40th stop 40a fits. If cut lumbers are processed with a large cross section, a T-shaped design of the stop can be dispensed with.
  • the stopper 40 has a defined and rigid position with respect to the upper pressure bar 26 during pressing. If the length of the bars to be produced is changed during a batch change, then the stop 40 must be displaced with respect to the upper pressure bar 26. This is done according to the invention here automatically, as will now be explained with reference to Figures 1, 10 and 11:
  • the stop 40 is rigidly connected to a locking slide 36, for example screwed. It may be useful to provide different stops for different wood cross sections, so that preferably include a plurality of stops to a press, depending on the wood cross section to be processed in each case the matching stop is screwed to the locking slide.
  • the locking slide 36 has a guide profile 36a and a movable portion 36b, which is arranged in the Z-direction movable on the guide profile 36a.
  • Guide profile 38a and movable portion 36b are coupled together by locking cylinder units 38, wherein each of the cylinders 38b are rigidly connected to the movable portion 36b and the pistons 38a are rigidly connected to the guide profile 36a.
  • the guide profile 36a surrounds a U-shaped guide rail 34 which is arranged on the first rack 32, which in turn is rigidly secured to the upper pressure bar 26.
  • the movable portion 36b of the locking slide 36 carries a second rigidly connected to the movable portion 36b rack 39 which engages in the locked state ( Figure 11) in the first rack 32. From the guide profile 38 a, a guide pin 31 protrudes into a Länhsnut 34 a of the guide rail 34th
  • the movement of the locking slide 36 in the X direction also takes place automatically, ie motor.
  • This has a consisting of two pulleys 18 and a drive chain 20 chain drive and a positioning slide 22 which runs in horizontally extending positioning rails 21 and whose position in the X direction by the chain drive is changeable.
  • at least one of the deflection rollers 18 motor preferably driven by an electric motor.
  • a Wegeaufillon not shown here is present, so that an accurate positioning of the positioning slide 22 can be achieved.
  • Precise positioning is important so that the teeth of the two racks are positioned before locking to each other so that they can interlock when locking. It is also possible to drive the positioning carriage pneumatically or hydraulically. Instead of a chain drive and the use of, for example, a rope spindle or belt drive is possible.

Abstract

L'invention concerne une presse pour la compression frontale de bois de sciage comprenant un bâti (10), une table de travail (12) essentiellement horizontale, un convoyeur d'amenée (56) destiné à amener un tronçon de bois de sciage suivant une première direction sur la table de travail dans une première position, un dispositif de déplacement destiné à déplacer le tronçon de sa première position vers une seconde position le long d'une seconde direction, une butée (40), contre laquelle la face frontale avant du tronçon de bois est pressée pendant la compression, ainsi qu'un piston de presse (58) mobile par rapport à la butée. Pour raccourcir le temps de préparation, la position de la butée (40) par rapport au bâti (10) peut être modifiée au moyen d'un dispositif de réglage, ce dernier présentant un premier dispositif de commande électrique, hydraulique ou pneumatique, permettant d'amener la butée dans une position arrêtée et une position non arrêtée.
