Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device for carrying out such a method.
  • the invention is based on the objects of specifying a more economical method for producing high-quality board stacking boards and a device for inexpensive but precise implementation of such a method.
  • the boards to be nailed together in layers are placed along a transport device (for example by means of a trolley, roller or belt conveyor) in a horizontal stacker and upright therein, standing with one long side on alignment rails running transversely thereto, layer by layer Positioned side by side and pressed flat against each other.
  • a transport device for example by means of a trolley, roller or belt conveyor
  • Each layer is nailed to the layer behind it by automatic nailing devices with pins across the main board level; for which the pin length is chosen in relation to the uniform board thickness so that each pin, under lateral offset against a previously nailed pin, through the current position, at least deeply engages in the most recent (previous) position behind. If the pin also penetrates deeply into the next, ie penultimate, layer through the next layer, then each board of each layer is nailed over its length to the boards of the adjacent layers to form a particularly stable bond.
  • the lateral offset from one nail position to the next in the longitudinal direction of the board is carried out by moving the nailing device (or several nailing devices arranged one above the other in the direction of the board width) relative to the board.
  • the positioning or step width of the nailing device which can be moved along the board on a trolley rail is numerically controlled in such a way that a certain nail position (in this preferred example through three boards) is just approached again at the fourth board presented. This reliably prevents a collision with a pin that is already in a lower position here.
  • the computer-programmed feed control of the nailing devices can also be carried out in such a way that certain defined and reproducible surface areas of the panels produced in series (for example for floor ceilings to be installed one above the other) are not nailed between the planks. Then these partial areas that have been spared from nailing can later be cut out of the finished plate again, for example for the passage of an exhaust gas chimney that extends over several storey floors, without running the risk that the cutting tool used for this collides with wire pins and becomes tool or tool Workpiece breakage and risk of splintering in the environment.
  • the oblique view of the drawing shows a plate 11 growing in its length 1 in that boards 12 are stacked flat in front of one another and nailed together by means of wire pins 13 to form a rigid connection.
  • the thickness 2 of the plate 11 is given by the width 4 of the boards 12, which are thus oriented transversely to the plate surface.
  • the width 3 of the plate 11 is given by the length 5 of the boards 12; however, if necessary, this is extended by a further board 12 'of length 5'; which does not have to be a uniform or shorter length 5 'as assumed for the principle example outlined.
  • trimmed (waste) boards 12, 12' are kept ready for a uniform width 3 and from there transferred to a conveyor 15 by hand or by means of a suction lifter or similar loading device. By means of this, the boards 12, 12 'are brought into the starting area of guide rails 16 of a horizontal stacker 17.
  • This loading can take place transversely to the board length 5 in the longitudinal direction of the rails; however, it is preferably carried out transversely to the straightening rails 16 and thereby - in order to save additional guide mechanisms - lying on a main surface, that is to say in a stable orientation of the boards 12 up to the front side against a board 12 ', 12) already in this loading position in the stacker 17, and then in this starting or loading area of the guide rails 16 of the horizontal stacker 17 stored over pivot fingers 19.
  • the board 12 (or the board sequence 12-12 ') is erected to the current position in front of the board 11 and standing on its side edge 20 which is then below - with the advance of a support beam 21 in direction 22 around one of the board Thickness 6 corresponding route - flat against the previous board position, that is to say on the end against the previous plate 11 (increasing its length 1) in the stacker 17.
  • the boards 12, 12 ' which have already been stacked to form the board 11 can be advanced by applying and advancing the current position which folds up.
  • the numerically controlled drive 23 for the swivel fingers 19 is connected to feed elements 24 in the form of conveyor chains or belts on or next to the guide rails 16 in such a way that the feed of the plate 11 in direction 22 from the feed plane of the conveyor 15 continues when the current board position is erected just by the distance which corresponds to the board thickness 6 which has been programmed into the control unit since it is uniform and known or is currently measured.
  • the currently loaded layer (or a sequence of younger layers at the same time) can be parallel to one another by means of a side of the starting area of the stacker 17 whose straightening rails 16 trimming saw 25 trimmed and thus the plate 11 are trimmed at the same time.
  • the Plate width 3 corresponds exactly to one and a half lengths 5 + 5 'of boards 12 available in magazine 14; so that the cutting process delivers the short boards 12 'to the magazine 14' for the full width 3 of the plate 11.
  • the current position positioned in this way is fixed by means of at least one automatic (compressed air) nailing device 28 which, along the current position (that is, in the longitudinal direction of the board 12-12 '), approximately like a trolley on a guide rail 32 above the fingers 19 and the stamp 27 can be moved successively to numerically predeterminable nail positions 29 (sketched by an x in the drawing).
  • the nailing device 28 could also be adjustable in the direction of the board width 4, that is to say transversely to this direction of travel; but in terms of apparatus, it is more advantageous to arrange at least two such nailing devices 28 on boards 12, 12 'of greater width 4 on a common feed carriage at levels one above the other and thus to move them along the rail 32.
  • the nailing device 28 shoots a wire pin 30 in the stacking direction 22 at each position 29 and thus approximately transversely to the main plane of the boards 12, 12 ′ into the current position and through it.
  • the Length of the wire pins 30 just about equal to three times the unit thickness 6 of the boards 12, 12 ', so that a wire pin 30 connects the three most recent (last) layers with each other. Therefore, at this position 29, no nailing should have taken place in the previous three positions, so that the same position 29 can be approached with the fourth position. This can be ensured very reliably by means of the numerical control for displacing the nailing device 28 - especially in combination with the feed control of the plate 11 which grows in layers by the drive 23 - in order to avoid nail collisions.
  • the current position is nailed to the last (previous) and the previous one with a lateral offset, so that the previous (last) is always connected to the most recent (current) on the loading side as well as to the penultimate position on the plate side , which results in a uniformly staggered two-dimensional and therefore very stable, reliable connection over the plate width 3 and length 1.
  • the nailing device 28 is steered in certain successive positions over certain partial lengths of the boards 12, 12 'in such a way that a nail-free area 31 remains in the surface of the plate 11.
  • the sketch takes into account (to the right and to the left of area 31) that in the vicinity of this area, for example to compensate for strength with regard to the intended mechanical stress on the plate 11, a staggered nailing 29 can be carried out in a program-controlled manner by appropriate grading of the nail positions 29.
