Definitions

  • the invention relates to a machine for trimming veneer packages according to the preamble of patent claim 1.
  • Trimming machines are used in veneer processing to trim the dried veneer sheets stacked into packages on their long sides. If the individual veneer sheets, the length of which is usually between 2.5 and 5 m and the width - transverse to the fiber - between 60 and 600 mm, are then to be assembled into larger formats on their long sides, the cuts of all veneer sheets must run exactly parallel so that no trimming is required to avoid gaps when assembling. Trimming machines used in this way are called joining scissors.
  • the packages are additionally trimmed, bundled and measured on their narrow sides before they are processed further.
  • Trimming machines with two knives which cut the two long sides of the packages simultaneously in one operation.
  • the packages inserted into the side of the machine are pressed flat on a table by a vertically movable pressure bar, then a knife guided on one long side of the table cuts from bottom to top and at the same time a knife guided on the opposite long side of the pressure bar from top to bottom.
  • the table or pressure bar surface opposite the respective knife serves as the cutting surface.
  • Such a generic machine for trimming veneer packs is described in DE-OS 2 915 707.
  • a disadvantage of this machine is that it can only be loaded and emptied manually via a longitudinal opening. Continuous, automatic loading is not possible. It is therefore only of limited suitability for installation in automated processing lines.
  • the invention has for its object to provide a generic machine for trimming veneer packages, which is automatically passed through by the veneer packages in the longitudinal direction.
  • This object is achieved by the characterizing features of patent claim 1.
  • the fixed table enables a conveyor to be installed between the table and the pressure beam. Since the cutting line of the lower knife is fixed, the packages can be aligned along this cutting line before entering the machine, e.g. on an upstream loading table.
  • the cutting width for each package - i.e. the respective position of the upper knife - can be easily before entering the machine, e.g. B. via an adjustable directional light.
  • the feature of claim 2 ensures exact transport through the trimming machine even with larger veneer widths. It has been shown that the accuracy of the cut of all sheets of a package is improved by a pressure bar according to claim 3.
  • the plates or the lower conveyor belt serve simultaneously as a cutting surface for the upper knife.
  • the feature of claim 6 ensures a uniform contact pressure on the edges to be cut, regardless of the set cutting width.
  • the two cutting lines can be easily defined.
  • the cross-sections can be defined at the same time using two additional straightening lights.
  • the area delimited by the directional lights can be automatically determined in a simple manner, as a result of which a subsequent, additional measurement of the veneer packs is no longer necessary.
  • a machine according to the invention for trimming veneer packs has a base frame of approximately 5 m in length and just over 1 m in width, which is built up from four vertical stands 1, lower cross members 2, upper cross members 3 and side longitudinal members 4.
  • a box-shaped trimming table 5 with a horizontal table surface is rigidly attached to the lower cross members 2, the length of which corresponds to the maximum package length (approx. 4.5 m) and the width corresponds to the maximum cutting width (approx. 600 mm).
  • the table 5 is stiffened in a pressure-resistant manner and covered with a plastic base 6 as the cutting surface.
  • a horizontal cutter bar 7 is fastened vertically and in the longitudinal direction in a guide 9 with a cutter 8 extending over the length of the desk.
  • Swing levers 10 actuated by hydraulic cylinders act on the cutter bar 7 and guide the cutter 8 cutting upwards when cutting along a circular path.
  • a dimensionally stable, box-shaped pressure beam 11 is suspended vertically movable and transversely displaceable in the frame, the underside of which is coated with plastic is parallel to the table surface and corresponds in size to it.
  • a knife bar 13 is fastened with a knife 14 in a guide 15 so that it can move longitudinally and vertically.
  • the downward cutting process is also corresponding to the lower knife 8 via the rocker arm 13 engaging rocker arm 16 with hydraulic cylinders carried out.
  • the suspension of the pressure beam 11 consists of two longitudinal rows of vertical, hydraulic, double-acting piston-cylinder units 17, 18, the cylinders of the row 17, which runs above the lower knife 8, are rigidly attached to the frame.
  • the associated pistons are each provided with rollers which run in guide rails 19 which are fastened transversely on the upper side of the pressure beam 11.
  • the pistons of the second row 18 of the piston-cylinder units are rigidly attached to the top of the pressure bar 11 along the edge adjacent to the knife bar 13.
  • the associated cylinders are fixedly connected to a longitudinal guide beam 20 which is fastened to the upper cross members 3 so as to be horizontally displaceable.
  • the transverse displacement takes place via two linear amplifiers (not shown), a threaded spindle, a chain drive or hydraulic cylinder can also be used.
  • Synchronization elements 21 - here racks with pinion - are integrated in the suspension of the pressure beam 11, which ensure a parallel transverse displacement and height adjustment of all edges of the pressure beam 11.
  • a transport device for the veneer packs in the form of two superimposed belts 22, 23 of smaller width than the minimum cutting width - here approx. 50 mm - leads through the frame in the longitudinal direction between table 5 and pressure beam 11.
  • the upper run of the lower belt 22 runs directly next to the knife 8 over the table surface, it also serves as a pressure bar. It has been shown that a slightly higher contact pressure along the cut edges has a positive effect on the cut quality. For this reason, the underside of the pressure bar 11 is also provided with a longitudinal pressure bar 24 of approximately 2 mm thickness in addition to the knife bar 13.
  • the input-side deflection roller 26 is located in front of a loading table 27, not shown in FIG.
  • conveyor belts 22.1, 23.1 running one above the other between table 5 and pressure beam 11 are used as the transport device. Both conveyor belts 22.1, 23.1 extend on the inlet side over the loading table 27 and on the outlet side over a removal device 29. While the lower belt 22.1 is somewhat wider than the maximum cutting width - its width therefore corresponds approximately to the table width - the upper belt 23.1 has a width somewhat less than the minimum cutting width. It runs right next to the lower knife 8 through the frame.
  • the transport device for the veneer packs consists of elastic, interconnected plastic or leather panels, each of the size of the table surface, which is intermittently, e.g. with chains, can be moved over the table 5.
  • the plates also serve as a cutting surface for the upper knife 14.
  • the upper conveyor belt 23 may not be necessary, since the packages do not have to be clamped in for a precisely guided transport due to the wide transport surface.
  • the packages on the lower conveyor belt of clamping devices e.g. automatically closing brackets.
  • the loading table 27 mentioned above is firmly connected to the frame on its narrow side on the input side.
  • Directional lights 30-33 are projected onto its table surface, one of which is in alignment with the lower knife 8.
  • a second longitudinal light 31 can be adjusted transversely and is connected to the transverse adjustment of the pressure beam 11 via a control. This control guides the upper knife 14 depending on the position of the directional light on its escape line.
  • two transverse lights 32, 33 are additionally projected onto the loading table.
  • a transverse light 32 is fixed, the second -33- is movable in the longitudinal direction of the table 27.
  • the position of this displaceable transverse light 33 controls the cut of a transverse trimming machine downstream of the longitudinal trimming machine via the feed of the conveyor belt 22.
  • the packages are bundled.
  • the area between the directional lights 30-33 is automatically calculated by the position of the movable directional lights 31, 33 from a connected computer. This makes a separate measurement of the veneer packs after the finishing unnecessary.
  • a machine for gluing the edges follows the longitudinal trimming machine according to the invention, followed by a cross-assembly machine.
