Definitions

  • the object of the present invention is a machine for gluing together laths which are inserted into the same across the conveying direction, this machine comprising a supporting table, a conveying device for the laths and devices for gluing and pressing the laths together.
  • Machines of this type are known, in which the conveying device for the laths is formed as a slide running forward and backward over a table.
  • This construction is not advantageous in that the laths must be laid in front of the slide in quick succession, for the slide is continuously reciprocated and the laths are immediately pushed under the usual pressing bars.
  • a lath has been brought into an inexact position in front of the slide it also comes into this position under the pressing bars, so that it is impossible afterwards to put the lath into correct position with regard to the others.
  • the machine according to the invention remedies all the above-mentioned inconveniences. It
  • the supporting table comprises conveying elements protruding only in so far above the supporting surface that between the conveying elements and the laths to be conveyed the friction necessary for conveying the latter is obtained, and that, after the supporting table, a transporting device is provided moving the laths conveyed by the conveying elements out of the plane of the latter in front of a second table on which the laths are glued together.

  • Fig. 3 is a section along the line IIIIII in Fig. 1b.
  • Fig. 4 is a partial view in the direction of arrow B in Fig. In.
  • Fig. 5 is a top view of the push beam

  • the screw l8 By means of which the stop H2 is fixed.
  • the handle screw I9 is loosened so that the screw l8 can be moved along the slit l6.
  • the position of the stop M is dependent on the length, i. e. on the extension of the plate to be made in the direction of fibre. This length is determined by the distance (Fig. 2) between the stop if? and the circular saw blade 28, by means of which the assembled laths 2
  • the shaft 23 of the saw blade 26 is pivoted on supports 22 fixed to the machine frame I and is driven by the pulley 24.

  • the bolt 40 besides, forms the pivot for the plates 45 and 56 which are rotatably connected with the haft 5 and the pivot 36 respectively. Owing to the arrangement shown, the drive of the roller 35 can follow any change in the vertical position of the latter.
  • the lower ends of the carrying bolts 48 are connected to levers 52 rotatable about pins 53 fixed to the frame I.
  • the other end of these levers 52 carries rollers 5 1 cooperating with cam discs 55 fixed to the shaft 3.

  • the springs Sid provide for the rollers 92 being constantly pressed against the cam discs 93.
  • the construction of the push beam 86 may specially be seen in Figs. 5 and 7. It has holes 95 open towards the table 62 .and separated from one another by ribs 96.
  • the ribs 96 go through the slits Q1 of the lifting bar GI between the bars I2, in this way, together with the transverse rib 98 (Fig. 3), pushing the lath lying on the lifting bar 6

  • the medial portion of the lever 59 is pivotally mounted on the beam 86 and at the one end, carries a hammer Hill], at the other end a pin IllI.
  • the lever 99 In the position shown in Fig. 5, the lever 99 is pressed by the spring I62, against the cam I03 fixed to the frame I. the lever 99 lying on the side of the pin Idl, in the position shown engages the pawl I68 rotatably fixed to the push beam 86 and influenced by the spring I855.
  • a stop I69 is fixed to the push beam 86 which, after a loosening of the screw Hi can be displaced for adapting its position to the desired length of the plate to be manufactured.
  • the table 62 on which the laths are glued together along their longitudinal edges, is formed by the bars 12 which are supported on the back wall El and on the U-iron I i3. Above the bars I2, bars 4 form a pressing bed. Each of the bars H4 is fixed to bolts N5, of which in Fig. 3 only one is shown for each bar IM. These bolts H5 are suspended on U- irons IIB of which only one is illustrated. Each bolt II5 carries a supporting ring III. Between this latter and the U-iron IIB a spring IIB is inserted for each bolt H5, pressing the bar II I belonging to it against the laths 2I on the table 62.
  • the width (vertical to the direction of fibre) of the plate to be manufactured can previously be adjusted on a counter.
  • This counter counts the laths joined together in the feed direction and as the width of the laths is known, the extension of the plate vertical to the direction of fibre can be determined from the number of laths used for each plate. Seen in Fig. 2, this counter is placed on the right side of the machine.
  • a lever I23 is loosely mounted, on which the rod I24 is pivoted.
  • the rod I24 is connected to a lever I23 the latter being pivoted on the frame I by means of the bolt I25.
  • This lever I26 carries a roller I21 cooperating with a cam disc I28 of the shaft 8.
  • a driving pawl I30 is rotatably mounted, a spring I3I being fixed to this pawl and to the lever I 23, which has the tendency of bringing the driving pawl I30 into engagement with the teeth of the ratchet wheel I32 loosely mounted on the pin I22.
  • a pawl I43 is, pivotally mounted on the frame I, being under the influence of the spring I42 and serving the purpose of holding the ratchet wheel I32, against the influence of the weight I35, in that position into which it has previously been brought by the driving pawl I36.
  • the pawl I43 can be brought out of engagement with the ratchet wheel I32 by the lever MI, and at the same time, operate the schematically illustrated apparatus Hi4 counting the manufactured plates.
  • the lever MI is rotated and locked by the arm I51 and the glue applying roller I5 put out of working position. Besides this, the lever MI disengages the pawl I43 from the ratchet wheel I32 and this, under the effect of the weight I35, commences to rotate in the clockwise direction. In the beginning it also takes along the lever I23 until the driving pawl I30 strikes against the cam I43 and, by the latter is brought out of engagement with the ratchet wheel I 32. Now the latter runs back until the pin I38 strikes against the upper edge of the lever I58. Lever I48 can again be released by means of the end I59 of the arm I37 either by hand or automatically and the whole is ready for manufacturing a new plate.
  • a plate e. g. a middle layer of a plywood plate
  • the worker may also place lath pieces on the table 3 which are shorter than the desired length of the plate in the direction of fibre, since tight butt joints between these pieces are guaranteed by the device shown in Fig. 5. Therefore, one may also take laths with knots, cut away these knots before bringing the laths upon the table 3 and then use these shortened pieces which are free of knots. All the laths are laid upon the table 3 side by side and one after another in the same way as they are arranged in the finished plate. As the conveying bands 4 are moved continuously, i. e.
  • the cam disc 55 presses the press bar 61 upon the next laths thereby preventing all the laths on the table 3 from being advanced.
  • the cam disc 68 raises the lifting bar BI and during the lifting of the lath on the bar BI one of the lath edges lying in the direction of fibre is supplied with glue by the roller l5.
  • the cam disc 93 moves the push beam 86 to the right and this latter pushes the lath lying on the lifting bar SI between the table 82 and the pressing bed formed by the bars H4.
  • push beam 86 and lifting bar BI are returned. If the latter is again in its lowermost position, the press bar 41 is lifted; the bands 4 move the next lath upon the bar BI, the abovementioned cycle begins anew and the second lath on the table 62 is brought into contact with the former lath and, on moving forward together, the second lath is glued to the former one. This cycle is repeated until the counter, in a manner described above, brings the glue applying roller 15 out of working position. The plate is finished.
