Definitions

  • the invention relates to a method and a device for producing a top layer for finished parquet.
  • the entire parquet board has a low height in order to be able to lay it like a carpet, without further structural measures, for example it is necessary to mill the lower edge of the door.
  • the top layer of a finished parquet must have a minimum thickness of 2 m in order to be allowed to use the name "parquet".
  • the thickness of the top layer which consists of a relatively hard wood, is determined by the mechanical requirements and the required mechanical strength.
  • parquet panels described leads to the fact that the top layer of the finished parquet has to be manufactured with high precision in order for the individual to be concerned Ensure slats of the parquet and to avoid gaps between the individual slats.
  • the object of the invention is to create a method and a device for producing a top layer for finished parquet, which, with a high degree of efficiency and a high degree of automation, enable the production of high-quality finished parquet.
  • the inventive method is characterized by a number of significant advantages.
  • the number of parquet slats provided on a parquet board can be designed as desired, very wide or very narrow slats can be used.
  • the parquet can be adapted to a wide variety of optical requirements.
  • the glue coating of the longitudinal edges of the parquet slats leads to a secure connection of the individual slats of the slat arrangement. It is not necessary to glue the end edges, since these are offset from one another and have only a relatively small area.
  • the strength of the lamella arrangement is not influenced by this, but rather the gluing of the longitudinal edges enables the lamella arrangement to be made sufficiently stable to be further processed as a top layer for finished parquet panels.
  • the trimming of at least one end face of the slat arrangement provided according to the invention leads to an exact dimensioning of the slat arrangement in the longitudinal direction of the slats. Trimming in the other dimension direction is not necessary, since the lamellae are manufactured exactly with respect to their longitudinal edges during their manufacture.
  • the step according to the invention of transferring the lamella arrangement by means of a lifting device to a press film is particularly advantageous since the preselected assignment of the lamellae is not impaired by the lifting process. It is therefore completely ruled out that the lamellae can be displaced or tilted relative to one another or can reach one another. This is particularly important for very thin lamellae. This is an advantage, since there is always the risk of individual slats being pushed over one another when they are moved laterally.
  • the individual lamellae of the lamella arrangement are pre-pressed in the longitudinal and transverse directions. This pre-pressing serves for tight contact of the individual lamellae and ensures that they are exactly aligned with one another in the subsequent final pressing process.
  • the parquet slats are fed in several tracks.
  • the feeding in several tracks makes it possible to carry out a visual check of the individual lamellae and their assignment and to take corrective action if necessary.
  • the possibility is created of replacing and eliminating slats or slat parts that are too short in the longitudinal direction. It is namely necessary that the lamellae always have a larger dimension in the longitudinal direction than in the transverse direction. This possibility of error exists in particular at the start area or end area of the respective lamella arrangement. An operator can thus exclude this possibility of error in a particularly simple manner, since the individual webs of the slats can be accessed without problems.
  • the parquet slats are preferably brought into flush contact with the system in a further working step.
  • the flush alignment of the parquet slats can be carried out by conveying on the individual webs with increasing conveying speed. As a result, the respective subsequent parquet slat is pushed up and placed on the previous parquet slat.
  • the cutting of the at least one end face of the lamella arrangement is preferably carried out in such a way that the lamella arrangement Order is promoted against an attack.
  • the rear end of the lamella arrangement can then be trimmed. This procedure is also particularly advantageous since the cutting process can be monitored by the operator and corrected if necessary.
  • the operator can replace individual slats either before or after cutting in order to improve the optical design of the slat arrangement.

  • the device is characterized by a number of significant advantages.
  • the pneumatic lifting device for the lateral transfer of the lamella arrangement.
  • Such a pneumatic lifting device which is provided with a large number of vacuum suction cups, ensures safe and uniform lifting of the lamella arrangement. This avoids that the individual slats are tilted or tilted towards each other or overlapping. This configuration of the lifting device is particularly advantageous in the case of very short cycle times.
  • the conveyor device comprises at least two conveyor belts which are parallel to one another.
  • a plurality of conveyor belts can also be provided in the longitudinal direction of the conveying direction of the lamellae, which are equipped with increasing conveying speed. In this way, the frontal contact of successive slats is ensured.
  • the longitudinal edge gluing station is preferably provided with glue application wheels for applying hot glue (PVAC or urea resin glue) to the longitudinal edges of adjacent lamellae.
  • the hot glue only leads to a gluing of the lamella arrangement due to the temperature effect in the plate press. This is particularly advantageous since the final exact alignment of the lamella arrangement is only available at this point in time.
  • the latter preferably has a stop extending transversely to the conveying direction of the lamella arrangement. This stop can be fixed, but it can also be advantageous to design the stop so that it can be pivoted or tilted out of the movement path of the lamella arrangement.
  • the pneumatic lifting device comprises a plurality of frame elements rigidly connected to one another, on each of which a plurality of vacuum suction cups are arranged.
  • the frame elements can be raised and lowered and moved transversely to the conveying direction of the lamella arrangement, in order to transfer one lamella arrangement each to a conveyor belt of a plate press. Since several arrangements of lamellae can be pressed side by side in the plate press at the same time, the lifting device is designed such that it can place the individual lamellae arrangements next to one another.
  • the plate press is conveniently designed so that it can be closed for pre-pressing to the extent that a press gap of approximately 1/10 mm results.
  • This press gap is sufficient to pre-press the lamella arrangement in the longitudinal and transverse directions. At the same time, it is prevented that during this pre-pressing process, individual lamellae are tilted or tilted or are stacked on top of one another.
  • the plate press can then be closed for the final pressing. This process can preferably be carried out via a toggle lever mechanism which ensures a corresponding gap width during the pre-pressing process.

  • a time pre-pressing die it can be favorable to form a stop bar in the region of the center line of the pressing surface of the plate press, against which the several laterally arranged lamella arrangements can be pressed.
  • This configuration leads to an improved utilization of the press capacity, since a plurality of lamella arrangements can be inserted on both sides.

Abstract

L'invention concerne un procédé et un dispositif qui permettent de réaliser la couche supérieure de parquets finis. Des lamelles individuelles de parquet sont transportées depuis des magasins de lamelles (1) sur les voies parallèles d'un convoyeur (2) et sont encollées dans un poste d'encollage des lisières (3). Les groupes de lamelles sont ensuite amenés contre une butée (12) et sont séparés au niveau des faces, dans un poste de découpe (4). Un dispositif de levage (5) permet de les transférer sur la bande transporteuse (6) d'une presse à plateau (7).
