Definitions

  • the invention relates to a feeding device for feeding a Veneierzusammensetzmaschine with veneer strips.
  • veneer splicing machines which assemble veneer strips at their longitudinal edges transversely to the grain direction to supply this veneer strip by hand.
  • This manual loading is due to the fact that the machine operator carries out a quality control in addition to feeding the machine with veneer strips.
  • a thickness control of individual veneer strips has to be carried out in order to sort out thin or too thick veneers and, on the other hand, a visual check is carried out.
  • the optical control not only aims to sort out unsuitable veneer strips, but also to ensure that an attractive pattern is obtained on the produced veneer carpet.
  • the feeder according to the invention for feeding a Veneierzusammensetzmaschine with veneer strip has a compact and physically small construction and can realize a charge of a variety of veneer stacks.
  • the charging device according to the invention comprises a magazine, a transport device and a portal gripper.
  • the magazine has a plurality of receiving compartments, which are arranged parallel next to each other to receive each a veneer stack.
  • the transport device is connected downstream of the magazine and conveys the individual veneer strips for veneer assembly machine.
  • the portal gripper has a plurality of grippers and is arranged above the magazine and the transport device. The grippers simultaneously remove veneer strips from the magazine and place them on the transport device.
  • the transport device comprises a first transport region and a second transport region, which are arranged in series one after the other.
  • the portal gripper places the veneer strips removed from the magazine on the first transport area.

  • a light table is arranged below the second transport area in order to illuminate the veneer strips from below.
  • a quality assurance of the subsidized veneer strips are made possible. If a damaged veneer strip has been discovered in the loosely conveyed veneer carpet, it can then be removed manually.
  • a releasable locking device is arranged between the magazine and the transport device.
  • the magazine can be released from the transport device.
  • the magazine is arranged interchangeably on the transport device.
  • a first and a second magazine can be provided, wherein the first magazine is fixed to the transport device and from which veneer strips can be removed, and the second magazine is being filled at a different location. Then, when the first magazine has been emptied, this can be quickly replaced with the second magazine, so that no interruption of the feed is necessary. While the second magazine is emptied by the portal gripper, at the same time the first magazine is refilled and provided. When filling the storage compartments can be paid attention to an attractive pattern of veneer carpet.
  • a lateral contact element is arranged on the magazine between the individual storage compartments.
  • the contact element is preferably removable.
  • the magazine can be quickly converted to different widths of veneer strips, for example, by removing every second contact element from the magazine.
  • the grippers of the portal gripper are designed as adhesive tape gripper.
  • the adhesive tape grippers comprise an adhesive tape strip which serves to remove the veneer strip from the veneer stack from the magazine.
  • the gantry gripper further comprises a blowing device for blowing a surface of the veneer strip before a gripping operation. This prevents, for example, dust o.a. prevents a secure gripping a veneer strip.
  • a spring-loaded slider is preferably arranged on each receiving compartment of the magazine.
  • the spring-loaded slider aligns the veneer strips.
  • the spring-loaded slider presses the veneer strip, for example, against a wall or a stop.
  • the magazine is arranged at an angle of 90 ° to the transport direction on the transport device.
  • the veneer strips removed from the magazine are transversely to the transport direction on the transport device stored so that they can be fed to a Querzusammensetzmaschine linear.
  • Fig. 1 is a schematic, perspective view of a charging device according to an embodiment of the invention.

Thus, the veneer strips are now stored in the form of a loose veneer carpet on the first transport area 4. Then, the laid veneer strips are conveyed by means of the first conveying element 4a in the direction of the second transport region 5. In order to avoid that the individual veneer strips are unintentionally conveyed one above the other, probes or sensors, such as optical sensors, may be provided.
