Definitions

  • the invention relates to a Kappvoriquessan extract according to the preamble of claim 1 and a method of capping according to the preamble of claim 8.
  • Kappvoriquessan extracten of the type mentioned serve an edge band projection on narrow sides of plate-shaped workpieces, these are in the context of the invention, in particular furniture panels made of wood or wood substitutes, separate to make the edge band flush with the narrow side.
  • Vorkappvoriquesen are known as from DE 101 24 081 C1 , which provide rough cuts in the edge band. After precutting a fine machining is required; this must be done with other aggregates to achieve the desired flush.
  • a trimming unit is used, which is mounted eccentrically. So it can be delivered to the workpiece and deducted after caps of this again without the past the trimming unit workpiece is obstructed.
  • the trimming unit is synchronized in its movement with the movement of the workpiece. The synchronization takes place as a function of the speed of movement of the workpieces transporting transport chain. This approach is inaccurate because the speed of the transport chain varies greatly due to inherent characteristics of the chain and is therefore extremely tolerant.
  • Such a Kappvortechnischsan Aunt is therefore suitable at best for a roughing. You need additional finishing units.
  • EP 2 311 612 A2 a device for machining workpieces which has a plurality of saw blades on a rocker. These are delivered to the workpiece to introduce a plurality of cuts therein to form a comb structure. For this purpose, the movement of the saws and those of the workpiece must be synchronized.
  • such a device is not suitable for the above-described Kappvorgang, since when caps are usually required other angles than 90 ° to the feed direction.
  • the object of the invention is to provide a Kappvoriquessan extract and a Kapprose with which both a Vorkappen and a fine machining with only one unit are possible.
  • the movement or the position of a probe element is evaluated for the control of the trimming unit.
  • This movement is detected by the control unit in the form of movement information, for example via an incremental encoder, and the feed movement of the trimming unit is controlled as a function of the movement or position of the feeler element.
  • the controller detects and evaluates not only the movement information, but also a predetermined cutting path of the edge band to be cut, in particular, if the chop saw as often usual, no cut 90 ° to the feed direction of the workpiece, but an angle smaller or larger than 90 °. In this way, the workpiece can be detected accurately and the edge band can be cut exactly and with minimal tolerance.
  • the usual tilting of the capping tool during caps resulting in clean Kapp réellen.
  • the eccentric on two parallel rockers with pivot bearings which may be coupled via a drive belt and / or a gearbox with the rotary drive.
  • This rocker arrangement allows a defined movement of the trimming unit, which preferably has at least one saw, during the delivery or the removal from the engagement area with the workpiece on a defined path.
  • control device controls the rotary drive. This is then done as described above in dependence on the speed of the probe element, which is held on the workpiece in plant and therefore always provides a measure of the speed of the workpiece.
  • the trimming unit performs a superimposed movement with a component in the feed direction and a component in the direction of movement during the feed movement. It can be provided in particular that the trimming unit is controlled so that the movement speed component of the trimming unit in the direction of movement of the workpiece and the movement speed component in the feed direction (Y) at least during capping produce a linear cutting motion.
  • the trimming unit is controlled in such a way that its movement speed component increases in the direction of movement after capping - in particular if the capping takes place in the region of the narrow side of the workpiece leading in the direction of advance of the workpiece - and / or smaller - in particular if Caps in the region of the trailing in the feed direction of the workpiece narrow side of the workpiece is - is as the feed rate of the probe element and / or workpiece.
  • the trimming unit is brought to a speed - in particular accelerated - which corresponds to the movement speed of the workpiece, which is detected by the movement of the probe element by the control.
  • the control synchronizes or accounts for the eccentric movement of the trimming unit with the feed of the workpiece, in particular with the additional inclusion of the predetermined cutting path on the edge band (i.e., the predetermined profile of the trimming point), so that a co-cutting of the trimming cut is achieved during the trimming operation.
  • the trimming unit is removed by accelerating the rotary drive from the path of movement of the workpiece.
  • the trimming unit is pivotable about a pivot axis perpendicular to the movement direction X and perpendicular to the feed direction.
  • two saws or processing tools one for the leading end capping and one for the trailing end capping, can be provided and delivered to the workpiece by pivoting the trimming unit.
  • 2 denotes a transport device with which the workpieces 1 are guided past the cutting device 4 along a movement direction X.
  • the capping device 4 is arranged on a bearing 3 and has a rotary drive 43, which is coupled to an eccentric device (41, 42).
  • the coupling is preferably designed such that a toothed belt 44 is guided around the shaft of the rotary drive 43 and guide sections 41a, 42a of the eccentric device 41, 42.
  • the eccentric 41, 42 may be otherwise in operative connection with the rotary drive, such as a gear or it may be provided on the shaft of the rotary drive 43, an eccentric.
  • a trimming unit with at least one drive 4a and at least one tool 4b, in particular a chop saw, arranged.
  • the trimming unit 4a, 4b or the tool can be mounted pivotably relative to the eccentric device 41, 42 in order to set the angle of attack of the trimming tool relative to the workpiece 1.
  • the trimming unit 4a, 4b delivered in the feed direction Y the workpiece. This means that the trimming unit 4a, 4b executes at least one movement component in the feed direction Y when delivering. Due to the eccentric arrangement, a movement component in the direction of the movement direction X is also executed at the same time.
  • the eccentric 41, 42 by two parallel arranged rockers 41 and 42 realized, which are pivotally hinged to the bearing 3 and coupled to the rotary drive 43 via a coupling element 44 in the region of their respective guide portions 41a, 42a. If the rotary drive 43 is actuated, then both rockers 41, 42 oscillate parallel to one another and move the trimming unit 4a, 4b connected to at least one rocker 42 on a fixed path, in particular a circular path, thus leading to combined movement with components in X as well as in FIG Y direction off.
  • the device according to the invention also has a control (not shown) which controls the rotary drive 43 in response to movement information.
  • This movement information is obtained from a sensing element 5 belonging to the arrangement according to the invention.
  • This probe element is controlled so that it is always in contact with a workpiece 1 to be machined, either on the trailing in the direction of movement X and / or the leading in the direction of movement X narrow side of the workpiece.
  • the current position of the probe element 5 thus always corresponds to the position of the front or the trailing narrow side of the workpiece 1 and can thus be used for positioning and control of the trimming unit 4a, 4b.
  • the movement data of the probe element 5, which can be generated approximately by an incremental encoder or optically, are in the form of motion information passed on to the controller, which knows where the workpiece 1 and thus with the trimming unit 4a, 4b to be approached Kappstelle of the running parallel to the direction of movement X narrow side and protruding edge band is located.
  • the controller now works so that it detects the position of the workpiece 1 as described and synchronized or offset with this position, the movement of the trimming unit 4a, 4b via the control of the rotary drive, so that during capping a synchronization (ie, substantially the same speed ) between the trimming unit and the direction of the trimming cut is achieved and the capping can be carried out with pinpoint accuracy, FIG. 2 ,
  • the eccentric mechanism ensures that the trimming unit 4a, 4b is withdrawn from the workpiece counter to the direction Y, thereby leading the workpiece in the direction X, so that the workpiece 1 transported in the movement direction X. is not obstructed by the trimming unit 4a, 4b, FIG. 3 , Similarly, it can be provided that when the projection of the overhang on the trailing narrow side of the workpiece, the speed (component in the direction of movement X) of the trimming unit after capping is lower than that of the workpiece, so that there are no hindrances here.
