Definitions
- the invention relates to a device, in particular a soft-forming device, for applying edge strips to the narrow sides of plate-shaped workpieces made of wood or wood substitutes.
- Edge coating devices in which more than one edge strip of the device is made available are sufficiently known, such as DE 27 22 414 A1, DE 10 2008 011 313 A1, DE 70 31 313 U, DE 10 2013 001 893 A1 or DE 27 22 225 A1.
- the edge band or the edge strip must be correspondingly coated with glue immediately before being pressed onto the workpiece.
- a gluing unit is usually used for this, in which the edge strip is coated with the appropriate adhesive in the process.
- the situation can arise that different adhesives have to be run on the same system, for example when the adhesives have to have different colors. This can only be achieved if a plurality of gluing units is used.
- the object of the present invention is to provide a device, in particular a softforming device, for applying edge strips to plate-shaped workpieces made of wood or wood substitutes, with which a simple change of the The adhesive used is possible, whereby it is ensured that the edge strip adheres consistently well to the workpiece regardless of the choice of adhesive.
- the device comprises a machine control, an edge strip magazine for storing and / or feeding a plurality of edge strips and at least two edge strip attaching devices which are designed to apply a fed edge strip by means of adhesive or glue application on the joint side or melting on the joint side - activate and then press against the narrow side of the workpiece, in particular by means of at least one pressure roller.
- the device also has a feed device which is designed to feed an edge strip removed from the magazine into an edge strip application device specified by the machine control.
- the feed device has a branching means and edge strip guide paths arranged between it and each edge strip application device.
- the branching means is designed to feed an edge strip coming from the magazine to an edge strip guide path specified by the machine control.
- the device has a movement device which is designed to move workpieces in at least one direction relative to the edge strip application devices.
- the device can be designed as a throughfeed machine, but a movement in several directions is also possible as a machining center. It is important that a relative movement between the edge strip application device and the workpiece.
- the plurality of edge strip application devices are preferably arranged one behind the other in the direction of movement of the workpieces.
- at least one of the edge strip application devices is preferably a gluing unit.
- other units for example lasers, hot air or the like, can also be used that are designed to activate, heat or melt the joining side of the edge strip or a functional layer provided there.
- the device according to the invention is consequently able to branch edge strips via the branching means according to the specifications of the machine control and thus coat them with different adhesives and attach them to the workpiece immediately after the coating.
- the adhesive on the edge band does not need to be kept warm and can be attached to the workpiece immediately after the adhesive has been applied without further transport.
- the invention also relates to a method for applying edge strips to the narrow side of a plate-shaped workpiece made of wood or wood substitute.
- the device described above is used here, the workpieces (on the narrow side to be coated) not being flat, but rather profiled.
- the machine control selects an edge strip application device or the associated edge strip guide path for each workpiece according to a specification and thereby causes edge strips to be fed from the magazine via the branching means and the selected edge strip guide path to the selected edge strip application device.
- the selection is made of the edge strip application device preferably on the basis of the properties, in particular the color, of an adhesive or glue to be applied to the edge strip in the edge strip application device.
- FIG. 1 shows a plan view of a device according to the invention.
- FIG. 2 shows an enlarged detail of part of the device shown in FIG.
- FIG. 3 shows the device shown in FIG. 1 loaded with workpieces.
- FIG. 1 there is an edge strip magazine 20, from which edge strips 1 are drawn into the feed device.
- 30 denotes a movement device on which workpieces to be coated with the edge strip 1 (cf. items 2, 2 'in FIG. 3) are conveyed in the transport direction X.
- the present invention also works in machining centers as long as there is a relative movement between the workpieces and the edge strip application devices 50, 60.
- the edge strip applicators 50, 60 are at the end of FIG.
- Feed device 40 arranged one behind the other in direction X.
- An edge strip guide path 42 or 43 is located between each edge strip application device 50, 60 and the magazine.
- a branching means 41 through which the elements drawn in from the magazine Edging strips are brought into a selected edging strip feed path 42 or 43 depending on the specifications of the machine control.
- feed means 44 are provided in order to convey the edge strip 1 to the respective edge strip application device 50 or 60.
- each edge strip application device 50 or 60 has a pressure roller 61 with which the edge strip 1 coated with adhesive is pressed against the workpiece.
- the device according to the invention works as follows:
- the machine control (not shown in FIG. 3) specifies a special type of adhesive for an edge strip 1 to be brought from the magazine 20 into the feed device 40, which is either in the gluing unit of the edge strip application device 50 or in the Edge strip applicator 60 is held.
- the edging strip is then drawn from the magazine 20 into the feed device 40 and at the branching means 41 into the predetermined edging strip guide path 42 or
- edge strip guided in the edge strip feed path 43 is then coated, for example, with glue or adhesive on the gluing unit 63 and then pressed onto the workpiece 2 by means of the pressure roller 61. Accordingly, a Edge strips 1 guided in the edge strip supply path 42 are coated with the gluing unit 53 and then pressed onto a workpiece 2 'by means of the pressure roller 51.
- gluing units other devices can also be used which are suitable for bringing the joint side of the edge strip 1 into a sticky state by heating, melting or activating. Such devices can include, for example, laser radiation, plasma radiation, hot air or the like.
