Definitions

  • the present invention relates to a machining apparatus for machining centers according to the preamble of claim 1 and a method for machining the edges of plate or strip-shaped workpieces using such a device.
  • the invention is directed in particular to the processing of plate-shaped or strip-shaped workpieces, which consist at least partially of wood-based materials and are provided with an edge.
  • edge projection is first milled flush and then deducted depending on the material with a scraper blade in a special pulling blade unit, as for example in the DE 199 15 673 is disclosed.
  • a machining center is available, with which the workpiece in one clamping can be completely edited.
  • the individual tools are successively brought to the clamped tool used.
  • the raw-sized workpiece is first formatted with a milling cutter and, after cleaning with an edge banding unit, an edge strip is glued onto the respective end faces. Since the edge strip usually has a greater width than the associated front side of the workpiece, this supernatant must be milled by a flush trimming unit. In order to achieve a higher quality of machining, often the flush-milled edge is reworked on its narrow side by means of a knife, a so-called scraper blade.
  • a post-processing of this kind depends in particular on the composition of the edge material and is carried out especially in tough materials.
  • a chip often forms over the entire length of the workpiece to be deducted, which accordingly amounts to 10 m for a workpiece size of, for example, 3 ⁇ 2 meters.
  • the resulting edge chip brings a number of disadvantages.
  • the chip is often in a frizzy shape and tends, not least by adhering adhesive, that it does not dissolve at one end of the unit. This can lead to the chip jamming when the workpiece is being passed under the contact shoe, ie between the contact shoe and the workpiece, thus producing a deteriorated machining quality. It also happens that due to the length of Spanes and the geometry of conventional suction hoods Span is not completely sucked off, and it can thus lead to blockages in the exhaust hood. Another disadvantage arises when replacing the unit in the tool holder, which should often be automated.
  • the invention is based on the idea to bring the at edge or narrow side machining resulting, at least one chip in a form that does not affect the further processing of the edge.
  • the processing device has a chip receiving section and a chip forming device, in which the at least one chip is geometrically variable. This makes it possible that the at least one chip after its formation, for example, crushed, folded, compressed, rolled, etc., so that it can be easily removed and a disturbance of the further processing of the edge or
  • Narrow side is excluded. In this way it is ensured that the quality of the edge or narrow side machining can be significantly increased, while at the same time machine downtime or even damage to the machine due to cut chips can be excluded.
  • the present invention is primarily applicable to machining centers.
  • workpieces which are at least partially made of wood-based materials, which are provided with a separate edge, or also monolithic workpieces (eg made of plastic) which have no separate edge , so that only one narrow side of the workpiece is processed.
  • edge is used, although the present invention is not limited to a separate edge.
  • the chip receiving portion can be formed in the context of the present invention as Spanleitkanal extending between the separating device and the Spanumform pleasing.
  • a chip guide channel can be provided without problems, for example, by a guide plate or by incorporating a channel-shaped recess in the device according to the invention.
  • the arrangement according to the invention of the chip-guiding channel between the separating device and the chip-shaping device ensures safe and trouble-free guiding of the at least one chip to the point of chip forming.
  • the processing device according to the invention in a machining center ein anbar, in the recording of a spindle of the machining center.
  • a separate drive must be, but the respective spindle for other tools (such as milling cutters, drills, etc.) or units (for example Kantenanleimaggregat etc.) can be used.
  • the chip-shaping device has a shearing edge and a cutting tool, in particular a milling tool. In this way, a rapid and clean crushing of the at least one chip can be achieved without the need for expensive devices.
  • the machining device has a flush milling unit whose milling tool preferably serves as cutting tool of the chip forming device.
  • the milling tool of the flush trimming unit fulfills two functions at the same time, namely on the one hand the flush trimming as such, and on the other hand the comminution of the at least one chip according to the invention.
  • the separation of the at least one chip from the edge to be processed can be done mechanically or in another way, wherein according to a development of the invention it is preferred that the separating device has at least one scraper blade. This gives a particularly high quality edge processing by means of a simple and reliable component.
  • the present invention further provides a method having the features of claim 5, wherein it is provided that the at least one chip formed geometrically after separation becomes.
  • the same advantages are achieved as in the device according to the invention, so that the quality and reliability of edge processing can be significantly improved with the method according to the invention.
  • the use of the method according to the invention is particularly preferred in cases in which the edge material or the at least one, separated chip consists of a tough material. These materials tend to form particularly long chips, so that the use of the method according to the invention - as well as the device according to the invention - is particularly effective.
  • tough materials may be mentioned plastics such as PVC, ABS, PE and the like, but also metals such as aluminum (or steel of comparable toughness), but the present invention is not limited thereto.
  • the invention provides that the geometric deformation of the at least one chip takes place substantially immediately after its severing and / or substantially simultaneously with a flush milling of the edge.
  • sources of error that may arise due to the at least one chip can be eliminated or eliminated at an early stage.
  • the number of successive steps is reduced, which shortens the duration of the procedure.
  • the apparatus and the method according to the present invention are used for processing plate-shaped workpieces, as shown by way of example in FIG. 1 in a schematic view.
  • the plate-shaped workpiece 4 according to FIG. 1 has, on a narrow side, an edge 4 'which has a projection with respect to the workpiece 4 both on the workpiece top side and on the underside of the workpiece. Of these projections, as will be explained in more detail below, a portion b is eliminated by milling and a portion a by means of a scraper blade.
  • the workpiece itself consists in the present embodiment of a wood-based material and may be formed for example by a double-sided veneered chipboard or the like, as used in the field of furniture, countertops or the like.
  • the edge 4 ' may also consist of a wood-based material, but in many applications, in terms of durability and visual appearance of a Plastic material or a plastic composite material, for example, has PVC.
  • FIG. 2 and 3 show a schematic, partial plan view and a schematic, partial perspective view of a processing apparatus 1 according to a preferred embodiment of the present invention.
  • the processing device 1 comprises a separating device 2 in the form of a scraper blade for separating the edge projection a shown in FIG. 1, whereby a chip is formed in each case.
  • this processing device 1 has a chip forming device 10, which is formed by a shearing edge 12 and a milling tool 14 in the present embodiment.
  • a different type Spanumform raised 10 may be used.
  • a chip channel 8 which serves as a chip receiving portion to receive a separated chip trouble-free, before it is changed by means of the chip forming device 10 geometrically.
  • FIGS. 4 and 5 Further views of the processing apparatus 1 from FIGS. 2 and 3 are shown in FIGS. 4 and 5 in a schematic side view and in a schematic sectional view, respectively.
  • the processing device 1 shown in FIGS. 4 and 5 has two separating devices 2, chip receiving sections 8 and chip-forming devices 10 and can thus process both an upper and a lower edge overhang 4 '.
  • connecting sections 16 are schematically illustrated in FIGS. 4 and 5 on the upper side of the processing device 1, by means of which the processing device 1 as a whole can be exchanged in a machining center, for example in the receptacle of a spindle or main spindle.
  • the replacement preferably takes place automatically, so that the processing device can be exchanged or replaced at short notice as needed.
  • the device 1 After a flush milling of the edge 4 ', not shown, in which the edge projection b shown in FIG. 1 is eliminated, the device 1 according to the invention is guided along the edge 4' of the workpiece 4 such that the scraper blade 2 has the edge projection shown in FIG a separates, whereby from the edge supernatant a, a substantially continuous chip 6 is formed.
  • This chip enters after separation into the chip channel 8 and is passed through this further in the direction of Spanicide vibration 10.
  • the rotating milling tool 14 At the end of the chip channel 8 of the chip 6 is detected by the rotating milling tool 14 and crushed in the shear edge 12.
  • the formed individual chips (not shown) are ejected and can be easily detected and removed by a known, not shown Spanabsaugvorraum.
