Definitions

  • the present invention relates to machines for preparing wide wood plates by gluing narrow wood sheets at their edges. More particularly, this invention is concerned with a sheet edge-gluing mechanism having two sets of endless chain arranged vertically one above the other and in contact with each other along a level surface and being arranged in such manner as to reduce the intervals between the chain plates with the advancement of the chain, thus producing a lateral pressure on the wood sheets inserted and conveyed horizontally between the upper and lower chain in order to carry out a perfect edge-gluing of said wood sheets.
  • the object of the present invention is to provide wood plates by gluing edges of ordinary long-slender thin wood sheets, to be used for manufacturing plywood panels.
  • Fig. 1 is a longitudinal cross-sectional view of the present invention
  • Fig. 2 is an enlarged partial plan view taken along the line 2-2 of Fig. l in the direction of the arrows showing the gluing of side edges of thin wood plates.
  • Fig. 3 is a transverse section taken along the line 3 3 of Fig. l in ythe direction of the arrows.
  • Fig. 4 is a transverse section taken along the line 4 4 of Fig. l in the direction of the arrows.
  • Fig. 5 is an enlarged detail perspective view of a plate and its connecting links forming part of the present device.
  • the frame 1 contains a pair of endless chains 1a and 1b which are arranged one above the other. That is to say, the upper endless chain 1a meshes with the driving ychain wheel 2 and the follower chain wheel 3, while the lower endless chain 1b meshes with the driving chain wheel 4 and the follower chain wheel 5. Both of said endless chains are in contact with each other at their adjacent medial portions between said driving ⁇ Wheels and said follower chain wheels. Both upper and lower chains are constructed i-n the same way.
  • Each chain plate 6 is narrow in width in comparison with its length and are of a tongue and groove formation at their side edges. Also, the chain plates are constructed in such a way that, when the interval between adjacent plates is diminished, their side edges are brought into contact with each other (as shown in Fig. 2) forming a continuous plane.
  • rollers 11 and 12 are attached to each en d adjacent the inner face of frame 1 there are attached the rollers 11 and 12 respectively.
  • Both upper and lower chains thus constructed areV guided by grooves provided in the frame in which they travel. That is to say, the contact surface between both chains (see Fig. 1) and each two rows of the guiding grooves 13 and 13' of the roller 11 and the guiding grooves 14 and 14 of the roller 12 are arranged in symmetry each on an upper and lower side of the contact surface of said chains.
  • the beginning and end portions of guiding grooves 13 and 13' are parallel to said horizontal contact surface of said chains, but the middle part of the guiding grooves 14 and 14 between the portion yof the chains corresponding to the part between lines C and D, shown in Fig. 1, is inclined in the advancing direction of the chain in such a way that said part is gradually extended away from the horizontal plane.
  • the beginning portion and end portion of the guiding grooves 14 and 14 are constructed parallel to a horizontal plane in ⁇ order to feed the chain by the chain wheel as smoothly as possible by making the spacing of the recesses on the peripheral surface of each chain wheel equal to the spacing of shafts 10 of the connecting links 9a and 9b when riding in the beginning and end guiding groove portions.
  • the track containing guiding grooves 13 and 14 of the upper chain 1a is arranged for up and down movement on said frame.
  • the track is hung by the bolts 18 from the transverse beams 17, which are fixed on both side walls of the frame, the track being pressed downwardly by the springs 19 wound around said bolts.
  • the upper chain may move in accordance with the thickness of the thin plates to be glued when the latter are interposed between the upper and lower chains.
  • Driving gear wheel 20 is Xed on the shaft of the driving chain wheel 4 of the lower chain and driving chain wheel 21 is similarly associated with the upper chain and gear train 22, 23 and 24 is arranged between the driving chain wheels 2 and 4.
  • Gear train 22, 23 and 24 drives chain wheel 2 at the same angular velocity as chain wheel 4.
  • Chain wheels 2 and 4 rotate in the directions indicated by arrows in Figure 1.
  • the heating apparatuses 25 and 25' which are supported by the transverse beam 17, heat the upper and lower face of the chain and promote the drying of the binding agent at the edges to be glued and hasten the gluing action.
  • theupper and lower chains are driven by the driving chain wheels 2 and 4 and the thin wood plates W, on the edge surfaces of which a binding agenthas been previously. coated, are inserted between the follower" chain wheels 3 and 5 one by one in series in such ⁇ a way that the plates are placed perpendicular to the advancing direction of the chain.
  • the gap X between thel thin plates is previously determined so as to be a little less than the amount of the decrease of the distance between the chain plates to be producedby the inclined guiding grooves.
  • the gap between each adjacent thin plate begins to decrease, and, at last, the edges comeiu contact with each other, giving the edge to be glued a lateral pressure.
  • a machine for producing wide wood sheets from a series of relatively narrow wood plates comprising a supporting fframe, two pairs of driven cog wheels rotatably supported with one pair above the other across ⁇ said frame, two series of pivotally connected links each providing an endless chain extending around one of said pair of cog wheels for being driven thereby, a plurality of plates each pivotally connected to a connected pair of said links, and means for guiding each of said link chains for moving opposing plates of said link chains toward one another along a horizontal plane and for spacing adjacent plates of each link chain horizontally apart at one end of said frame while progressively moving said adjacent plates in a longitudinal direction of said chains to edge-edge contact at the other end of said frame whereby narrow wood plates having glue on the edges thereof can be placed on said plates at said one end of said frame, held in said horizontal plane by said opposing plates and progressively moved into edge-edge contact in a horizontal direction by said plates, forming a wide wood sheet thereof.
  • said guiding means consists of a pair of grooved tracks supported by said frame for each of said link chains with one groove extending horizontally and the other groove extending on an angle thereto, a plurality of rollers each carried by one of said plates and moving in said horizontal track and a plurality of rollers carried by ⁇ said links and moving Vin said angularly extending track.
