Definitions

  • the invention relates to a cutting unit according to the preamble of patent claim 1.
  • such cutting units are arranged as chop saws on said continuous machines on longitudinal guides, which are parallel to the direction of passage of the workpieces.
  • longitudinal guides which are parallel to the direction of passage of the workpieces.
  • the delivery of the sawing tool is transverse to the direction of passage of the workpieces, and after performed Kapp Songs after returning the tool to its original position, the return of the chop saw to its original position to start from here the next work cycle can.
  • the support for holding the chop saw with its linear guides here represents a cross support, in which the linear guides lie in superimposed planes. Accordingly, for the process of the chop saw in the direction of passage of the workpieces on the one hand and transverse to the direction of passage to the other separate drives required.
  • longitudinal guides have a considerable length, which may be up to 1 m.
  • US 3143021 discloses a cutting unit according to the preamble of claim 1.
  • the invention has for its object to provide a cutting unit of the type mentioned, which requires a shorter body length in the direction of passage of the continuous machine and allows higher throughput speeds and cycle times of the workpieces.
  • the oscillation movement forced on the support which is likewise affected by the cutting tool, has no acceleration peaks, since there is no directional reversal with dead points, which is unavoidable in the case of a linear stroke. Due to the oscillation movement, the support and the parts built up on it move along each circle or ellipse at any point or point. Moreover, the oscillation movement takes place in a single plane, and a single oscillation drive can be provided for this purpose, whereby the mechanical oscillation can be generated in a simple manner by implementing a rotational movement. This allows a high rotational speed along the elliptical or circular oscillation path during a single oscillation period corresponding to a cycle of the cutting unit.
  • the support can be stopped exactly after each cycle to its original position to go through on a corresponding start signal to another oscillation period.
  • the difference between the duration of a Working cycle and the timing of the continuous interfaces on the workpieces easily compensate.
  • a cutting unit of the type according to the invention can be found in the Kappstation such continuous machines in which the processing of the narrow sides of the workpieces includes the gluing of an edge strip, the supernatants of the forward and backward corners of the workpieces must be cut.
  • the new cutting tool is also suitable for other cutting operations that must be performed on the narrow sides or on the adjacent workpiece surfaces. This may be, for example, cuts in a seal or piping on which cuts or notches must be made.
  • a workpiece transport device 1 which may be a transport chain, as are common in those pass-through machines on which plate-shaped workpieces for the furniture industry or interior work are processed in particular in the field of narrow-plate sides.
  • the workpieces 2 there are narrow side surfaces 3, which lie with their longitudinal direction in the passage direction predetermined by the transport device 1, and the workpieces 2 also have in the usual square or rectangular formation transverse to the direction of passage lying narrow face sides 4.
  • These narrow faces 3, 4 are coated in many cases by means of an edge strip which is applied in a Kantenanleimstation the pass-machine.
  • the edge strip is on the respective narrow side surface, here the narrow surface side 3, which lies in the direction of passage of the machine, both at the forward in the direction of passage and at the rear corner of the workpieces 2, and it must be a chop be made to cut off the edge strip flush with the lying transversely to the direction of narrow side surfaces 4 of the workpieces 2.
  • a cutting or cutting tool 5 usually a circular saw blade, which is arranged on the motor shaft of a Kappmotors 6.
  • the cutting tool 5 with the Kappmotor 6 sits on a support 7, which in turn is arranged on an oscillating drive 8.
  • the oscillation drive 8 ensures that the support 7 moves with the parts built thereon at each point along an elliptical or circular path, the departure of this circular path between the two vertices, the connecting line is parallel to the direction of passage of the workpieces 2, sufficient carry the cutting tool 5 for the Kappvorgang on a piece of the passage path with the workpiece 2 with adapted speed.
  • a superimposed transverse stroke is carried out between the two vertices of the oscillation path whose connecting line runs transversely to the passage direction of the workpieces 2.
  • This transverse stroke is matched to the necessary depth of cut, which must be provided for the severing of the respective edge material.
  • the motor 9 drives a drive gear 10, which is arranged with an upright axis between two hubs 11, which have along their circumference a toothing 14, with which the drive gear 10 meshes, which is particularly clear Fig. 2 evident.
  • the turntables 11 have on their tops protruding driver 12 in the form of eccentric, both drivers 12 have the same eccentricity, the two turntables 11 are equal and are driven by the motor 9 and the drive gear 10 synchronously with the same direction of rotation. Always here is the angular position of the two drivers 12 relative to the axis of rotation of the turntable 11 is the same.
  • the support 7 has a lower support plate 13, the underside receptacles 20 for a play-free, rotating receiving the driver 12 of the drive plates 11 has.
  • On the mounting plate is a cross guide 14 with an upper support plate 15, which can be adjusted according to in and against the direction of passage of the workpieces 2 and perpendicular thereto. This is merely the adjustment of the cutting tool 5, otherwise the mounting plate 13 and the support plate 15, which are to be regarded as cross slides, at a working cycle at least in the direction transverse to the direction of passage of the workpieces 2 against each other not displaceable, in principle, these two plates 13, 15th also fixed in the direction of passage of the workpieces against each other in the work games be. In this case, the oscillation movement transmitted by the oscillation drive 8 to the support 7 is transmitted exactly to the cutting tool 5.
  • a push button 19 is movably arranged on the support plate 15 so that it can be retracted into the passage region of the respective workpiece transverse side 4 and withdrawn without being yielding in the direction of passage of the workpieces, so that it against the force of the pressure element 18 in delayed Oszillationsantrieb 8, the capping tool 5 can move relative thereto.
  • the oscillating drive 8 can be accelerated relative to the passage speed of the workpieces 2, so that a support in an analogous manner to the in Passing direction rear workpiece transverse side 4 can take place during the Kappvorganges a defined position of the cutting tool 5 relative to the relevant workpiece transverse side 4, with which the edge strip is cut flush.
  • the in Fig. 1 reproduced cutting unit in the trimming station of the continuous machine is supplemented by a mirror-symmetrically constructed and arranged cutting unit in order to be able to cut off the protruding ends of the edge strip at both ends of the coated workpiece narrow side 3.
  • the cutting tool 5 is arranged with the Kappmotor 6 on a support plate 16 which can be pivoted relative to the support plate 15.
  • the pivoting path is defined by a link 21, which may be incorporated into one of the two plates 15, 16 and in which engages the respective other plate 16, 15 with a protruding cam or the like, as from Fig. 3 evident.
