Definitions

  • the invention relates to a device for transferring adhesive Panels from a feed conveyor to a veneer station, one movable clipboard at least one plate from the feed conveyor removed and moved towards the veneer station.
  • the plates in question are generally on both sides Adhesive, especially glue, coated so that it can be attached of the cover layers in a plate press under the influence of heat and Pressure can be pressed into a composite body.
  • the clipboard always carries with it a storage area a plate from the feed conveyor to the intermediate station, with its other shelf a plate from the intermediate station to Veneer station.
  • the path the plates take from the feed conveyor to the Intermediate station and then from the intermediate station to the veneer station cover is always the same length, since the two storage surfaces of the Clipboard are mounted in the same frame.
  • the object of the present invention is that improve known transfer device in that it for different plate sizes can be used without doing the above Having to accept disadvantages.
  • the Characterize invention with a high conveying speed.
  • This object is achieved in that the movable Clipboard places the plate on another clipboard that is movable relative to the first clipboard and the plate in the veneer station promoted.
  • the essence of the invention is, therefore, the two storage surfaces to become independent clipboard, so that two receives independently working units.
  • the transfer device is therefore much more flexible and can be optimally adapted to the respective Plate sizes are adjusted, both with regard to their route, as well as their driving speed.
  • the two clipboards are so movable against each other that they are in one Position overlap one another, whereas in the other position they overlap Transfer area of the feed conveyor on the one hand or the veneer station on the other hand. Due to the contradiction and the common Overlap area can be very short cycle times and accordingly achieve high implementation capacities.
  • the specialist has various options. It is particularly favorable if the one clipboard is in one Movement direction extending vertical slot and in this The other clipboard is supported. Let it through Both clipboards are supported on the floor with short frames and there is no need for portal storage.
  • the vertical slot mentioned is expediently located in the downstream, second clipboard because then the first clipboard, which, in addition to the horizontal method, also vertical lifting movements must perform, supported in the center of the center of gravity can be. For the rest, both clipboards are supported through trolleys.
  • both clipboards can be moved vertically.
  • the downstream clipboard can only be moved horizontally and not vertically and the transfer of the board they carry to the veneer station by at least one adjustable stop behind the rear panel edge.
  • Preferably two swiveling stops are used, the Frame of the veneer station are stored.
  • Figures 1 to 5 show in the left part a feed conveyor 1, on which one-sided, mostly double-sided glued panels 2 arrive.
  • the feed conveyor 1 extends vertically to the drawing level and it consists of numerous, in the conveying direction with successive spiked rollers 1a.
  • Figures 1 to 5 show a veneer station 3, in which the plates 2 fit snugly on a ready covering layer be laid on and in most cases also the top of the Plate is covered with another top layer.
  • the onward transport of the such plates in the press are perpendicular to the plane of the drawing and is not shown any further.
  • Both clipboards are on trolleys 14 or 15 assembled and horizontally movable in the plane of the drawing, the first clipboard 4 also in the vertical direction.
  • the glued panels 2 from the feed conveyor 1 lifted and passed to the second clipboard 5. This then places the panels on a ready top layer in the veneer station 3 from. In general, this top layer is also there on one Conveyor belt, so that the coated plate is then in the press can be driven.
  • the clipboards 4 and 5 consist of rakes arranged Support arms 4a and 5a, which extend in the plane of the drawing and are spaced from each other perpendicular to the plane of the drawing.
  • FIG. 1 shows a plate 2 on the feed conveyor, under which clipboard 4 is already located.
  • This clipboard extends with their rake-like support arms 4a in the spaces between the spiked rollers 1a and can thus pass between them Drive up and lift out plate 2. This state is in Figure 2 shown.
  • both clipboards move outwards again, whereby the carrying arms 4a may still perform a slight lowering movement, to get below the level of the spiked rollers 1a, while the Support arms 5a preferably always maintain their height.
  • the support arms 5a have reached their desired position above the veneer station 3, so swivel stops 6 from the side or from above behind the rear edge the plate 2 - see Figure 5 - so that when moving back the support arms 5a stripped the plate and onto the one below it Top layer is deposited.
  • the support arms 5a are on it Top sloping down towards the free ends and the stops 6 make a slight downward movement when the support arms 5a are retracted, so that they remain in contact with the plate to be stripped.
  • the first clipboard lifts 4 the next plate out of the feed conveyor 1 and drives this to the right in the transfer position, as shown in Figure 3 is. As soon as the second clipboard 5 has also arrived there, the handover and subsequent transport continues in the described Way on.
  • the height of the first clipboard 4 is adjusted by an above of the carriage arranged lifting member, in particular a cylinder-piston unit.
  • FIG 6 shows a cross section through the two clipboards, wherein the feed conveyor is shown exaggerated for reasons of clarity becomes.
  • the first clipboard 4 can be seen below in the transverse direction continuous support arms 4a. Your storage on the trolley 14, which like said height must be adjustable, takes place in the middle via a carrier 4b.
  • the support arms 5a of the second clipboard 5 are not centrally, but at its two outer ends with the trolley 15 connected.
  • the support arms 5a do not run through, but leave in the middle Area a slot 7 running in the conveying direction is free.
  • This slot allows it, the central horizontal support 4b with its support arms 4a to move past the support arms 5a up or down and thus the lifting movement from the feed conveyor as well as the depositing movement to realize on the second clipboard.
  • the support arms 4a are dashed shown in an upper position 4a '.
  • the invention is therefore characterized by higher positioning accuracy, higher Working speed and optimal adaptation to different Plate sizes.
