Definitions

  • the invention relates to a Veneierzusammensetzmaschine with at least one slide, are guided on the glued veneer pieces, wherein the slide rail is associated with a heating element.
  • veneer splicing veneer pieces are glued together on their narrow sides.
  • the two veneer pieces to be bonded are cut into parallel strips, then provided with glue at their edges and then glued together in the veneer assembly machines.
  • the veneer pieces are guided by transport systems through an adhesive zone.
  • the gluing zone on the one hand, pressure is exerted on the joint formed between the veneer pieces to be glued, and on the other hand the glue is cured with heat.
  • the heat is usually generated by heating elements in the form of electrical resistance wires, which are arranged in thermally conductive radiators so that they deliver their heat to them. It has proven to be useful to arrange a plurality of radiators in a row to deliver the heat over a larger area on the slide rail.
  • the slide rail thus extends over a plurality of radiators and thereby prevents impact edges are formed in the glued together veneer. So that the slide is not on the Adhesive sticks in the joints, the slide rail is provided with a non-stick coating.
  • the task of the slide rail is to transport the heat in the glue and the adjacent joint area on the one hand, and on the other hand to keep the individual veneer pieces flat.
  • the resistance wires first deliver their heat to the radiators and then to the slide rail, only indirect heating of the slide rail is possible. Furthermore, due to the large number of required radiators a complex construction, which also prevents the slide is sufficiently supported to exert the required pressure on the veneer pieces. In addition, the known radiators are relatively rigid elements, which allow flexible adaptation of the slide rail to different veneer thicknesses only very bad.
  • a veneer splicing machine on which the preamble of claim 1 is based having at least one slide rail on which veneer pieces to be glued are guided, wherein a heating element is integrated into the slide rail.
  • the slide rail is provided with a longitudinally extending groove in which an insert made of copper, bronze or another flexible and highly thermally conductive material is arranged, wherein in the insert a receiving groove for at least partially receiving the heating element is provided.
  • Another veneer splicer is in the DE 39 12 314 A1 explained, are provided in the heating register, which are workpiece side recessed in the press plates.
  • the object of the invention is to improve the known veneer splicing machine.
  • the heat is introduced directly into the slide rail, since the heating element is integrated into the slide rail. This allows a heat transfer can be saved, so that a better efficiency is guaranteed. Furthermore, the radiators can be completely eliminated, whereby the heat loss generating surfaces are reduced. Another advantage is that the slide rail can be supported at many points regardless of the radiator lengths.
  • the inventive design also means that the slide is flexible and thus adapts to the veneer, while the radiator previously used stiff elements formed and thus poorly adapted to different veneer thicknesses and at the beginning and end of the veneer pieces, resulting in a Can cause misalignment of the joint. Characterized in that the slide rail is provided with a groove extending in the longitudinal direction, a position-safe arrangement of the heating element is ensured. In addition, the arranged in the groove of the slide insert made of copper, bronze or other flexible and highly thermally conductive material ensures good heat transfer from the heating element to the insert and from there to the veneer pieces.
  • the heating element is designed as an elongated thin heating cartridge.
  • Such cartridges are z. B. marketed by the company. Hotest.
  • the heating element dissipates its heating power lossless possible to the slide
  • the heating element is preferably held non-positively in the receiving groove, esp.
  • the heating element can also be held in a form-fitting manner in the receiving groove.
  • the slide rail is flexible in its longitudinal direction.
  • a slide rail is created with an optimized cross-section and optimum flexibility, the low moment of resistance by many force application points allows a very good investment in the veneer surface. This makes it much better possible to guide the edges of the veneer pieces to be glued exactly flush to one another.
  • the slide rail on a thermally insulating cover, which surrounds the insert at least at its longitudinal edges. This ensures only a small heat loss to the environment and the adjacent transport elements for the veneer pieces.
  • the cover may also surround the slide on three sides. This makes it possible to use heating temperatures in excess of 200 ° C without adversely affecting transport elements made of plastic or similar sensitive materials, such as plastic link chains or toothed belts.
  • connection of the slide with the cover can be done in two ways. According to an advantageous embodiment, it is provided that the insert is connected via a positive connection with the cover, esp. Via a dovetail connection. This allows easy attachment of the slide rail to the cover.
  • the insert can also be connected to the cover via a frictional connection, in particular screwed or glued.
  • the slide can have a flat cross-section.
  • the insert is provided with a lug and the receiving groove for the heating element is at least partially formed in the approach.
  • the heating element may also be held in the groove via an additional holding element according to an advantageous embodiment.
  • the heating element can also be designed as a thin film with conductor tracks as resistance heating and be applied directly to the slide rail.
  • FIG. 1 shows a schematic structure of a veneer assembly machine 1, in which individual veneer pieces 2, 3 are folded together at their edges.
  • the veneer assembling machine 1 has a fixed base 4, a lower slide rail 5, an upper slide rail 6 and pressure elements 7. Between the two slides 5, 6, the veneer pieces 2, 3 are guided in the arrow direction.
  • the lower slide rail 5 is mounted on the base 4, while the upper slide rail 6 is pressed by the pressure elements 7 against the lower slide rail 5.
  • the two slide rails 5, 6 are heatable, so that the veneer pieces 2, 3 guided between the slide rails 5, 6 are heated in the joint area.
  • the upper slide rail 6 is flexible in itself, so that the pressure elements 7 exert an optimal pressure on the veneer pieces 2, 3 in order to guide the edges of the veneer pieces 2, 3 to be glued in one plane.
  • the upper slide rail 6 is shown. It has a cover 8, which consists of a thermally insulating plastic. This cover 8 is provided with a groove 9. In this groove 9, an insert 10 is inserted in such a way the cover 8 surrounds the insert 10 on three sides.
  • the insert 10 consists of a flexible good heat conducting material, such. B. copper or bronze o. The like.
  • a longitudinally extending receiving groove 11 is provided, in which a heating element 12 is inserted.
  • the heating element 12 is an elongated, thin heating cartridge, z. B. from the company. Hotset trained.
  • the heating element 12 is provided with a power supply 13 and is inserted through a slot 14 in the slide rail 6.
  • FIGS. 3 and 4 show the details "A" and "B" of the slide rail 6 shown in FIG. 2. It can be seen that the insert 10 is connected to the cover 8 in a form-fitting manner via a dovetail connection.
