Definitions

  • the invention relates to a coating device which is set up in particular to coat a plate-shaped workpiece on narrow surfaces.
  • the invention also relates to a method.
  • panel-shaped workpieces are provided with a coating material, in particular with a so-called edge band, on a narrow surface.
  • coating devices for applying a coating material are constructed in such a way that a narrow surface of a workpiece can be coated per pass.
  • By coating a single narrow surface of a workpiece it is possible for workpieces with different dimensions to be coated one after the other during operation of the coating device.
  • Corresponding different coating materials are supplied from stores. If plate-shaped workpieces are each provided with a coating material on several narrow surfaces, several passes are required. This means that the throughput z of such a machine is relatively low, even if there is a high degree of flexibility as a result of the procedure mentioned.
  • the invention is based on the object of providing a coating device and a method for coating a workpiece which, with a high throughput, offers increased flexibility.
  • the coating device comprises a first application device for applying a first coating material to a first narrow surface of the workpiece and a second application device for applying a second coating material to a second narrow surface of the workpiece. Furthermore, the coating device comprises a first printing device for printing the first coating material.
  • the coating material mentioned is in particular a strip-shaped coating material, which is also referred to as edge band.
  • the coating device can include a pre-treatment device, in particular comprising a cleaning device, and/or an after-treatment device, in particular comprising a drying device, such as a UV drying device, which are arranged in such a way that the surface to be printed with the printing device or the printed surface is pre-treated or post-treated can .
  • a pre-treatment device in particular comprising a cleaning device
  • an after-treatment device in particular comprising a drying device, such as a UV drying device, which are arranged in such a way that the surface to be printed with the printing device or the printed surface is pre-treated or post-treated can .
  • the first application device, the second application device, the first pressure device and/or the second pressure device can be pivotable, in particular in order to apply and/or print coating material on a side of the workpiece, which side of the workpiece is inclined.
  • a side can be a narrow side which is inclined at an angle deviating from 90° with respect to the broad surface.
  • first attachment device and / or the second attachment device is a pressure roller or a Have pressure shoe.
  • the coating material can be pressed onto a narrow surface of a workpiece using the pressure shoe.
  • Forming rollers or forming shoes can also be used.
  • the coating device can have a first format processing unit, in particular comprising a rotating processing tool, for processing the first coating material applied to the workpiece, and a second format processing unit, in particular comprising a rotating processing tool, for processing the second coating material applied to the workpiece.
  • a trimming unit and a drawing unit can each be provided in order to trim a coating material provided on the workpiece and to process the transition to the broad side.
  • the first pressure device is arranged after the first application device in the direction of movement of the first coating material.
  • the coating material is first applied to the workpiece and then printed using the printing device.
  • the printed area can be arranged extremely precisely.
  • the second printing device can be an inkjet printing device, it being preferred for the second printing device to have print heads for different colors.
  • the second pressure device is arranged after the second application device in the direction of movement of the second coating material.
  • the coating material is first applied to the workpiece and then printed using the printing device.
  • the printed area can be arranged extremely precisely.
  • first pressure device and the second pressure device are arranged opposite one another.
  • a precise and simplified coordination of the printing processes can take place, in particular if, for example, a wood decor is to be imitated by the printed decor.
  • a decoration is created on the narrow surfaces that pretends that wood structures such as grain, knots or annual rings extend through the workpiece.
  • the first and/or second printing device can be set up to print coating materials of different thickness, cross-sectional shape and/or width.
  • the coating device thus has a high degree of flexibility.
  • the coating device can include a conveyor device, in particular a conveyor belt, conveyor chain or a conveyor belt, for moving the workpiece. Such an arrangement ensures a high throughput.
  • a method for coating narrow surfaces of a workpiece having the following steps: applying a first coating material to a first narrow surface of the workpiece, and applying a second coating material to a second narrow surface of the Workpiece, wherein at least the first coating material is printed.
  • the method has the advantage that, in addition to a high throughput, each workpiece can be processed individually. In particular, a change of decor during operation is made possible. However, the provision of large amounts of different coating materials can be omitted.
  • first narrow surface is arranged opposite to the second narrow surface.
  • a workpiece can be coated on both sides.
  • the printed material in particular ink, can dry during the movement from the first printing device to the first attachment device, if necessary using a drying device, so that pressing on of the printed coating material is guaranteed without affecting the printed portions.
  • the coating material is printed after it is attached to the workpiece, the printed area can be arranged extremely precisely.
  • the second coating material is printed.
  • the printing of the second coating material can be performed similarly to the printing of the first coating material.
  • the method can be used extremely flexibly. It can be provided that a first coating material and a second coating material, which have the same color, thickness and/or width, are printed. In this way, flexibility can be increased again.
  • the workpiece can also be held or fixed at least temporarily. According to this embodiment, an extremely variable production can be implemented.
  • first and/or second coating material can be made of a plastic material, or it can be a veneer, preferably real wood veneer. In particular, it is an edgeband material.
  • a workpiece can be, for example, a workpiece made of wood, a wood material or a composite material.
