Definitions

  • the invention relates to a finger press for the production of finger connections of boards provided with finger joints on their end faces in finger cutters and indicated with glue on the finger joints.
  • medium-high and high-performance continuous presses are used, which have an upper and a lower plate belt, which force-push the boards through the press.
  • the gluing pressure must be 50 to 100 kg per square centimeter, i.e. with a usual board cross-section of 25 X 4 cm, 5,000 to 10,000 kg feed force. If the boards are 4 to 5 m long and 10 or more connections are crimped per minute, there is a high energy requirement. With a feed rate of 50 m per minute, 45 kW are required for a press generating 5,000 kg or 90 kW for 10,000 kg. Apart from the complicated construction of such presses, this effort is very high. With cycle presses, a holding pressure must be exerted on the two boards to be joined, which is usually twice the feed pressure.
  • the object of the invention was to develop a finger press with a significantly lower energy requirement, simpler construction and a smaller installation and operating area.
  • the presses according to the invention meet all the requirements and conditions set for the task. It is a particular advantage that the endless board tracks produced with such presses after very short dwell times instead of the otherwise necessary 8 to 24 hours in the plywood presses can be conveyed.
  • the finger joint press shown in the drawings has a table 5 which is movable on tracks 1 and 2 with rollers 3 and 4 (FIG. 3) in FIG. 1 on the left.
  • table 5 At this table 5 there are articulated joints 6, on which lever arms 7 are articulated, which are connected at their lower end in further joints 8 with a horizontal pull rod 9 in a force-locking manner.
  • a pressing device 10 arranged above the table 5 has a longitudinal beam 11, on the underside of which rails which are transverse to it 12 are welded, which in turn carry bridges 13 on their underside, which grip across the table 5, on which 12 shafts 14 lie between the rails. Press shoes 15 are provided on the undersides of the bridges 13 for resting on the boards 16 to be pressed.
  • tension members 17 are articulated, which at their lower ends together with the lever arms 7 in joints 8 are non-positively connected to the pull rod 9.
  • Further lever arms 18 are arranged between the upper ends of the tension members 17 and the lever arms 7, so that lever arms 7, tension members 17 and the further lever arms 18 form rigid triangles which can be pivoted in the articulation points of the joints 6.
  • the pull rod 9 engages and can raise the shaft 14 in its horizontal movement by pivoting the triangles or press it down. The same arrangement is provided on the other side of the table 5.
  • a second table 19 is arranged on the right in FIG. 1, the pressing device 10 'of which is mirror-inverted with the pressing device 10 of the table 5, with tie rods 9' also at the lower ends of the triangles 7 ', 17', 18 'are articulated.
  • the tie rods 9 and 9 ' are connected between the tables 5 and 19 with a working cylinder 20 with which they are apart or in their longitudinal direction can be pushed together, the triangles performing the described pivoting movements.
  • the mode of operation is as follows:
  • the working cylinders 20 move the tie rods 9, 9 'in the direction of the arrows 21, 22 and thus the tables 5, 19 apart.
  • the pressing devices 10, 10' are raised, so that the boards to be pressed can be inserted under them.
  • All movement functions of the finger joint press described can be carried out by working cylinders or in their place by electric motors driving screw spindles. Programming for the coordination of the individual movement processes is possible without difficulty, so that the entire work process can run continuously automatically.
  • the pressed boards can be transported from the finger joint press described on a belt without mechanical stress after cutting to a plywood carrier press, where their gluing finally hardens.
  • the above-mentioned dwell time in the finger press is sufficient for a connection that meets the requirements of this transport. In this way, parking and storage space can be considerable be saved.
