Definitions

  • the invention relates to a machine for assembling veneer strips in a pass on a machine table, with transport means mounted in the machine frame, which pull the veneer strips together with their abutting edges, preferably driven transport disks, and an undulating or zigzag-shaped adhesive thread over the abutting edge area on the Top of the two veneer strips laying on the adhesive thread feeding device.
  • Such a veneer splicing machine is known from US-A-3,547,735, with which, however, only a flat veneer connection can be made through the glued-on connecting thread over the abutting edges of the veneer strips.
  • the object of the invention is to improve such a machine in such a way that in addition to the veneer connection by the glued connecting thread in the abutting edges of the veneer strips, an additional connection is made, which also widens the deformation of the composite veneer strips in corner or arch areas Avoids butt joints.
  • the machine should be provided with simply constructed and safe-acting means.
  • the machine should have good access to the glue application device, so that its tools can be cleaned or replaced in a simple manner without the need to remove other equipment of the machine.
  • the glue application device should therefore be able to be serviced outside of its work area in a short time, the veneer strips on the work table being able to remain in place. This means that the movement of the veneer strips is only briefly interrupted for the short maintenance process.
  • the glue application device should also enable a good distribution of the glue to the tools provided for the application without the need for a special drive motor.
  • the invention is intended to design a tool carrier for the glue application device of the machine in such a way that contamination of the bearings and drive gears of the glue application disks are avoided, and that the glue application disks can be cleaned or replaced in a simple manner. Contamination of the parts of the tool carrier is to be prevented by an exact metering of the glue, the channels and spaces guiding the glue should be well sealed.
  • the object is achieved according to the invention in a machine of the aforementioned type in that on the machine frame in the direction of veneer transport in front of the thread feeder, one side coating the longitudinal edges (butt edges) of the veneer strips with glue and behind this, in front of the thread feeder, at least one Hot air nozzle is arranged, the application device having a housing fastened to the machine frame, the upper side of which forms a horizontal veneer support surface which extends in extension of the transport and support surface of the machine frame which shows the means of transport.
  • the machine according to the invention is equipped with an additional glue application device, with which glue is applied to the veneer abutting edges during the passage of the veneer strips before the connecting thread is glued on, so that in addition to the veneer connection, a glue joint on the edge is made by means of the connecting thread glued to the surface.
  • the veneers Due to the plate-shaped transport discs, the veneers are firmly pulled together with their abutting edges and the glued-on connecting thread then holds the veneers together securely to harden the glue.
  • This additional glue connection prevents the joint edge of adjacent veneers from widening even when the veneers are deformed into corners or curves.
  • White glue that adopts colors and varnishes is preferably used as the glue, so that even coloring is possible in the abutting edges.
  • the application device is followed by at least one hot air nozzle, which acts on the glue in the abutting edge area and causes a pre-setting, so that a favorable adhesive force is achieved when the veneers are pulled together.
  • the machine is simple and inexpensive and shows a rational way of working, it enables the production of perfect veneer panels.
  • the glue application device preferably contains a tool carrier arranged underneath the machine table, which can be lowered and displaced horizontally from the area of the machine table transversely to the conveying direction of the veneer strips, in the working position on the free end of the piston rod provided with a support roller, one vertically on the machine frame supported pressure medium cylinder and is articulated via two identical parallel parallelograms, each consisting of a lower articulated rod and an upper articulated rod, to two horizontal connecting rods arranged transversely to the conveying direction of the veneer strips.
  • the glue application device can be pulled out in a simple manner by pulling on a handle like a drawer under the machine table, after which the tool carrier with the tools and the glue supply devices are exposed for maintenance.
  • Each push rod is preferably axially displaceably mounted in two sliding bushes, which are held by two fixed webs arranged one behind the other at a distance transversely to the conveying direction of the veneer strips, each of two glue application disks held in the tool carrier via a tool carrier and a drive shaft with a drive shaft attached to the Webs rotatably and axially slidably mounted, designed as a spline drive shaft is connected.
  • This arrangement enables the entire bearing sleeve to be released and removed quickly from the bearing body, so that the glue application disk held by the bearing sleeve can be cleaned from all sides. After the cleaning process, the bearing sleeve with the glue application disc can then easily be reattached in the bearing body. If the time required for the revision of the glue application disc is to be kept as short as possible, it is also possible to use another bearing sleeve with a glue application disc after the bearing sleeve has been removed, after which the tool carrier is available again for further processing.
  • the machine for assembling veneer strips 10 consists of a machine table 12 fastened to a machine frame 11 and several devices arranged in a straight line one behind the other partly below and partly above the machine table, a glue application device 13, an adhesive thread feed device 14 and a transport device 15 for the Veneer strips 10.

  • the entire glue application device can be pulled out of the machine transversely to the conveying direction of the veneer strips 10 via a handle 44 arranged on the carrier plate 43 on the outside of the machine. This movement is determined by the mounting of the push rods 27 and the spline shafts 38.
  • the cross member 42 also carries two glue containers 45 and two glue feed pumps 46 arranged on the outside of the carrier plate 43, which suck in glue from the glue containers 45 via suction lines 47 and feed these to the glue application disks 17 in the tool carrier 16 via pressure lines 48. Excess glue is returned to the glue containers 45 through overflow lines 49.
  • the glue feed pump 46 is driven by the gearboxes 33, each gear 33 driven by the cardan shaft 36 driving the glue feed pump 46 assigned to it via a drive shaft 50 and a chain drive 51. In this way, no special drive is required for the glue feed pumps 46; they also receive their torques via the gears 33 from the drive wheels 34.
