  • the main idea of the invention is that the stacking means for vertical stacking are designed. This measure will initially ensures that the structurally complex horizontal arranged conveyor for the emerging Board stack in favor of a much simpler vertical There is no need to position the board stack assembly. Farther can be in the forming stack by appropriate Board arrangements already openings for z. B. doors or Provide windows without the stack movement or Storage must be respected. In contrast, the Conveying device for horizontally operating systems Board length must be observed regularly.
  • connection device Nail device can also automatic nail feeder for vertical nailing relatively easy to implement.
  • the stacking means a board layer support to arrange the connected and / or to be connected Single boards covered with growing vertical Stack height from a maximum height according to the Stack growth to achieve the desired stack height, however at most up to the possible maximum stack height, after lowered below.
  • This ensures that the top board layer in relation to the entire device always occupies the same position in the vertical direction. This brings advantages when loading as well as possibly when connecting the boards, e.g. B. by nails.
  • means of transportation for positioning of one or more boards for a board layer in the essentially parallel to the one to be built Board layer stacks are present. It is special advantageous if the means of transport in relation to the forming stack of boards are arranged so that on the Boards fed in a vertical direction lie above the stack of boards building up. This measure is particularly preferred if in the area of Means of transport for transferring a board layer into the Board layer stacking position possibly already on one existing board layer stacks are provided and the Transfer means a parallelogram-like Include shifting device.
  • the displacement device can advantageously with transfer fingers work together that is a gap between modes of transport and bridge the actual board stack position.
  • the device according to the invention is in the range of Transport means a stop for exact positioning and in the case of several boards for abutting the board layer in the longitudinal direction before the transfer of the board layer intended. This measure can be based on the Pre-positioning a smooth transfer of one Ensure the board layer in the board layer stacking position.
  • the stacking means have a tilting device for tilting of a vertically completed board stack into one horizontal removal position.
  • the tilting pad can be a simple conventional forklift or a roller conveyor Pick up the board layer stack after the tipping process.
  • the connecting device a Nail equipment includes. So that the advantages of vertical stacking arrangement can be fully utilized, it is preferred if the nail device in the area above the vertical board stack is arranged so as to hold the nails to be able to shoot vertically.
  • the Nail device preferably along the board layer stack automatically movable. In this way, one can Set up the full length of a board stack serve.
  • the nail device comprises at least one nail outlet opening. It is cheap if near the at least one Nail outlet opening at least one pressing means for Holding down the boards is provided. By this measure it is ensured that the boards are in the nailing process do not move to an undesired position.
  • a pressure medium can e.g. B. a pressure roller can be used.
  • the nailing device lowers before the nailing process.
  • the Nail device can be designed so that it for touches down on the board to be nailed by one Release the safety lock, which then the nail weft triggers.
  • the nail device comprises two staggered pneumatically operated nail guns. That way a comparatively inexpensive nail device realize.
  • the boards can also be dowelled or the board connection can be done by a size press occur.
  • the device 1 in FIG. 1 comprises a base frame 2 to monitor the system on both sides Catwalk 4 is arranged for an operator 3.
  • On Board layer stack 5 is placed on one in the longitudinal direction continuous board layer support 6 (see also Fig. 2 and 3).
  • the nail device 7 comprises two staggered in the longitudinal and transverse directions pneumatically operated nail guns 8, 9 with nail magazines 10, 11.
  • the nail guns 8, 9 are each on one vertical guide rod 12 and a horizontal one Guide rod 13 slidably mounted. Between Nail guns 8, 9 is at least one pressure roller 14 present to hold down the boards to be nailed down can be lowered below. They are exemplary Nail outlet openings 14, 16 of the nail guns 8, 9 in the Edge area of the board layer stack positioned.
  • the whole Nailing device is on one along the board stack Track 17 longitudinally movable with guide rollers 18.
  • To the A drive 19 is used in the automatic process.
  • the running rail 17 with guide rollers 18, the drive unit 19 and one Energy supply 20 for the drive unit 19 are on one Crossbar 21 mounted on the base frame 2.
  • a board 22 to be stacked is via a roller conveyor 23 with rollers 24 essentially arranged in parallel next to the board layer stacking position (see also Fig. 4).
  • the rollers 24 of the roller conveyor 23 are crossed by a V-belt 25 from a Drive unit 26 driven.
  • a transfer beak 27 is provided, the one between the rollers 24 of the roller conveyor 23 Guide rod 28 is movable. 2 is the extended position of the beak 27 completely and the Basic position shown in sections.
  • a delivered board layer in the Board layer stacking position serves as a ruler Profile element 29.
  • a parallelogram construction 30 can the profile element 29 by means of an axis of rotation 31, which is rotated via a lifting cylinder 32 and lever arms 33, move towards the board stack position.
  • the axis of rotation 31 is stored at bearings 34, 35 and 36 in a defined manner.
  • the one Entry conveyor belt 40 and an exit conveyor belt 41 disposes.
  • the quick-cut system 39 is in one Work rack 42 positioned that the exit conveyor belt 41 is level with the roller conveyor 23 (cf. Fig. 4).
  • Examples are on the work rack 42 of the Schnellkappstrom 39 two board stacks 43 and 44 with z. B. 3 and 6 meter boards. Of the Schnellkappstrom 39 z. B. an operator 45 suggested what stack they put a board on the Input conveyor belt. Then the Schnellkappstrom 39 through the cutting process. Useless Board portions are carried through on the exit conveyor belt Ejector 46 pushed from the output conveyor belt 41.
  • Boards cut to length from the quick-cut system 39 are via the output conveyor belt 41 of the device 1 fed and into the roller conveyor 23 into it transported.
  • the roller conveyor 23 runs until that delivered board is completely on the rollers 24 and then stops. Only when the beginning of a subsequent one When the boards are inserted, the roller conveyor starts again. The process continues until the roller conveyor there is a complete board layer 49. Then drives on Entrance of the roller conveyor up a stop 47 (see. Fig. 4). in the Following this, the roller conveyor runs backwards and pushes the Boards against this stop 47. This closes the Butt joints of the boards and the board layer is clearly on Stop positioned. Now the transfer beaks 27 between the rollers 24 towards the front Board layer stack position.
  • the next step will be the profile element 29 via the parallelogram construction 30 pushed as far in the direction of the board layer stacking position until the board layer between the profile element 29 and one lateral stop 48 (see Fig. 2) clamps. Thereupon move the transfer beaks 27 back to their basic position and the board layer 49 is at some distance from the Board layer stack through the profile element 29 and side stop 48 clamped. Now that goes too Profile element 39 via the parallelogram construction 30 in return to the basic position and the board layer 49 is noticeable the board stack 5.
  • the board layer support 6 moved into the nail position via the spindle drive 37.
  • the nail carriage moves from the end position to the Nail position z. B. 30 cm from one end of the Board stack and 1.2 cm from each Outer edges of the board layer.
  • the stop 47 up to Board layer stacking position is sufficient to fill any gaps close in the case of multiple single boards.
  • the Nail device 7 on the board layer stack initially the pressure roller 14 hits the surface of a board, to push the board down and secure for the Fix nailing process. Also lie down on the side arranged rollers 50 (see Fig.
