Definitions

  • the invention relates to a web edge assembly for the automatic attachment of a strip or band-shaped edge material with an integrally formed fastening web on narrow sides of a plate-shaped material provided with a groove for the fastening web.
  • Edge materials on the narrow sides of plate-shaped workpieces have been known for a long time.
  • an edge banding machine is disclosed in DE 37 02 154 AI with which a flat, band-shaped edge material can be attached to the narrow sides of plate-shaped workpieces.
  • This known edge banding machine is advantageous in that the pressure roller used to press on the edge material can be wholly or at least partially guided around the circumference of the workpiece in question.
  • a cross support that can be moved in the direction of two axes is provided, which guides the pressure roller along two coordinate axes, which are usually perpendicular to one another.
  • a cutting device is also provided on this edge banding machine for cutting off the edge material.
  • An edge banding device that has a similar basic structure to the machine from DE 37 02 154 AI is known from EP 0 510 231 AI.
  • edge banding machines allow the gluing of a flat, strip or band-shaped edge material to the narrow sides of plate-shaped workpieces with a clamped workpiece, in which the corresponding devices can be moved around the workpiece in a program-controlled manner, however, no edge material with a molded-on fastening web can be glued on. This means that these machines are limited to very special areas of application.
  • the edge materials which can be machine-glued on the machines mentioned, mostly consist of PVC and are glued to them to protect the narrow sides of the workpieces.
  • the edge material is a strip with a flat contact side, on which the strip with the narrow side of the workpiece is placed using an adhesive layer.
  • the attachment of web edge materials i.e. Edging with a fastening web has so far only been possible with stationary rolling machines, such as those sold by Heinrich Brandt Maschinenbau GmbH. With these devices, the workpiece had to be guided past the corresponding devices for introducing the web of the edge material. This means that program-controlled attachment of web materials is not possible. In addition, this process can only be carried out manually and not automatically.
  • top master a stationary machine
  • the workpiece is held on a rotating workpiece table and rotated thereon.
  • the devices necessary for pressing in a web edge are placed on this rotating workpiece by means of a resilient bearing and the web edge is pressed into a corresponding groove in the narrow side of the workpiece. Due to the rotating workpiece, this machine can only be used for smaller workpieces.
  • the technical problem on which the invention is based is to provide a web edge unit with which a strip or band-shaped edge material with a molded-on fastening web can be attached mechanically and program-controlled to the narrow sides of a workpiece provided with a groove for receiving the fastening web.
  • the invention is based on the idea of providing, for the first time, a web edge assembly which can be exchanged in a spindle unit of a processing machine, so that the assembly can also be used against others
  • Processing units such as a milling unit, etc.
  • a processing machine in the sense of the present invention can be either a continuous machine with an integrated spindle unit or a so-called processing center with at least one
  • Act spindle unit The former can be used for essentially straight and slightly curved workpiece narrow sides.
  • the web edge unit is installed in a stationary but replaceable manner in the continuous machine.
  • the latter can also be used for workpiece contours that are more curved and have different radii. Since the unit according to the invention now has a connection device (quick-change device), it can be optimally used for both types of machine.
  • fastening web of the edge material is now guided for the first time, so that it can be introduced into the corresponding groove and pressed on.
  • adhesive is optionally applied to the fastening web, so that the fastening web, which is preferably provided with a barb profile, forms a positive fit together with the hardening adhesive in the groove and is thus securely fastened without the fastening web being applied with great force Nut must be pressed in, which at Narrower workpieces, which no longer have a greater residual wall thickness to the top or bottom of the workpiece, can lead to an undesirable “bulging” by pressing in the fastening web. This "bulging” is avoided with the technology according to the invention.
  • An assembly according to the invention thus has a connection device which can be exchanged into a spindle unit of a processing machine, in particular a processing center.
  • this connection device with a
  • an assembly according to the invention optionally has an adhesive application device with which the adhesive can be applied to the fastening web of the edge material either continuously or in sections.
  • the application of adhesive is necessary or appropriate depending on the material used and the cross section of the web.
  • an edge material feed device is provided with which the edge material can be guided to the narrow side of the plate-shaped workpiece or to the optionally available adhesive application device and in which a guide device is integrated, which is used to guide the edge material
  • Fastening web serves. However, this is optimally designed so that a band-shaped edge material can be attached to the unit without a fastening web.
  • lateral guide edges are simply provided on the guide device, between which the edge material is guided in a laterally guided manner. In the case of a profile with a fastening web, this is guided in an intermediate space in the guide device. An optimal execution will be explained in detail later.
  • the web is not first pressed completely into the groove provided for this purpose with a pressure roller, but for example only up to half the web height.
  • the web is then fully pressed in with one or more pressure rollers.
  • only one pressure roller is provided, with which, in a first pass, the web is only half-pressed into the groove, as described above. In a second pass, the web is then pressed in completely with the same roller; i.e. the workpiece contour is traversed twice.
  • edge material is not subject to too much "flexing work", which means that there may be length changes in the material at different times, which could lead to a widening of the butt joint in the case of 360 ° encasing, which would be undesirable and could even lead to scrap of the workpiece.
  • the edge material feed device comprises at least one driven transport roller, which can either be driven by the spindle unit via the connection device or has its own electric drive.
  • the transport roller transports the edging material by frictional engagement with the fastening web of the edging material. This enables the edge material to be guided and transported on the fastening web.
  • the existing fastening web is used optimally for insertion in the unit by performing a double function.
  • the fastening web is used for guiding as well as for transporting the edge material.
  • the frictional engagement with the fastening web can be further improved with a counter-pressure roller opposite the transport roller, which can optimally be moved towards or away from the transport roller.
  • the fastening web thickness and also the frictional connection between the transport roller, the counterpressure roller and the fastening web clamped in between can be adjusted in this way.
  • the counter pressure roller is optimally movable pneumatically. Because a compressed air supply is provided via the interface of the machining center and is also useful for other equipment on the unit.
  • Feeding device comprises a plurality of guide strips which form a sliding support for the inside of the edge material and between which the fastening web is guided. This means that the edge material in the unit is guided precisely to the side as well as in a vertical direction. As already stated, an edge material can be glued to the same unit according to the invention both with and without a fastening web.
  • One or more guide strips can be adjusted for optimal adaptation to different cross-sections of edge materials to be introduced with fastening webs.
  • the distance between the guide strips can thus be adjusted.
  • An optimal work result can be achieved if one or more pressure rollers are connected downstream of the at least one pressure roller. Due to the pressure rollers, the edge material already attached to the narrow side is redone pressed, so that possible irregularities in the introduced edge material are eliminated.
  • the glue is ideally applied to the fastening web using one or more glue application nozzles.
  • the nozzles are arranged on one or both sides of the fastening web, so that the fastening web on both sides facing away from each other, which come into contact with the groove walls, as well as the inside or plant edges, are covered with an adhesive, in particular a hot melt adhesive layer.
  • an adhesive storage container with which the adhesive application device is connected in the unit, essentially stationary in the machining center.
  • This has the advantage that the unit is lightweight and thus the mass to be moved can be reduced; what is important for the travel accuracy.
  • the adhesive storage container is arranged on the unit.
  • the adhesive storage container provided on the unit is optimally dimensioned such that the adhesive is sufficient for one or more clamped workpieces.
  • Another adhesive storage container is additionally present on the processing machine, via which the container arranged on the unit is refilled when the unit is returned to a special storage magazine of the processing machine.
  • the glue storage container can optimally be supplied with compressed air.
  • the adhesive can thus be pressed out in a predetermined amount to the adhesive application nozzles.
  • the edge material trimming device is equipped with a pneumatically operated trimming knife or a trimming saw. It is advantageous here that an edge material clamping device is provided with which the edge material can be absolutely clamped in the assembly, so that there is no offset or slipping of the edge material when the edge material is cut.
  • the joint is optimally made as follows.
  • the edge material is introduced and, at a predetermined distance from the edge material end which has already been inserted, which can be determined by the CNC control, is not pressed in or is pressed in only incompletely.
  • the edge material is cut with a slight excess or short length to the joint with the trimming device.
  • the pressure roller is lifted off and pressed on just before the butt joint. This creates a kind of "loop".
  • the contour in the joint area is now traversed again with the pressure roller pressed on. So that the previously not or only incompletely pressed edge material is pressed towards the joint. There is no need to reset the unit if there is at least one pressure roller that then presses in the "loop".
