Definitions

  • the invention relates to a woodworking machine, in particular format saw with a stop system, wherein the workpiece to be machined by a machining tool rests on the support surface of a support table, with several stops for guiding the workpiece, wherein at least two stops together on a base body of the stop system with different distances to the machining tool arranged and movable respectively in or out of the support surface by movement of the base body.
  • Stop systems for processing machines are known.
  • the workpiece to be machined is placed on the support surface of a support table and guided to a stop.
  • the stop is adjusted to the desired width before machining the workpiece and then performed the workpiece on this stop for processing.
  • Such a stop system is known for example from the document DE 36 37 713 C2.
  • a positioning device for plate or rod-shaped workpieces is presented in processing machines, in which on the level of the support surface for the plates to be machined or rod-shaped workpieces a plurality of stops is arranged by simply pivoting about an axis in the plane of the editing table or Rest table can be swung. All stops are arranged on a single shaft and by means of an actuating element differently adjustable and each individually used.
  • the positioning stops are arranged one behind the other in the machining direction or conveying direction and each have the same distance from each other.
  • the embodiment shown here is structurally very expensive and therefore expensive.
  • this proposal is very cumbersome in the operation, since the respective individual attacks are to press or to control. A short-term and rapid change of the attacks, for example, due to a format change is not possible with this proposal.
  • a sliding table saw are also known.
  • Such sliding table saws have a trimming table, which passes by a saw blade.
  • a cross table is usually attached on the trimming table and, with appropriate dimensions, also on the transverse table.
  • the stop or the stops are then located on the transverse table and usually reach to on the trimming table.
  • stop systems are known, with at least two together arranged on a base body of the stop system stops, wherein the stops are movable by a movement of the body in or out of the support surface.
  • the invention has the object to develop a stop system, which no longer has the disadvantages described above.
  • the object of the invention is achieved by a woodworking machine according to claim 1.
  • the joint movement of the stops by the movement of the body, the operability is greatly facilitated.
  • the position of the main body serves to activate or deactivate the possibly arranged at different positions stops.
  • the attacks are not only moved back by the base body with respect to the support surface.
  • all other movements are conceivable which cause the stop to move away from the support surface, that is to say in such a way that the stop is no longer able to interact with the workpiece.
  • a woodworking machine is provided with an accurate and flexible stop system on the support table side, which is used for universal execution of cuts, in which in particular exact parallelism of the edges to be cut is promoted against the voltage applied to the attacks edge.
  • the contact surface for example, when loading with workpieces, such as large wood panels, can be cleared very quickly by simply all attacks are lowered below the contact surface, without the attacks or the attacks bearing parts must be disassembled consuming.
  • the invention allows that the stop system has a plurality of stops and, for example, only one stop when it is not needed, is lowered and another stop remains in use, so forms a stop for the workpiece.
  • each lowerable stops are used on a support beam, which are moved, as needed, upwards over the support surface when they are needed.
  • the attacks of the body are arranged at different distances from the machining tool and in different positions, in particular height or angular positions on the base body.
  • the base body is movable at right angles to the bearing surface and the stops have different lengths, that is to say elevations, and the respective stop is switched on or off by the position of the base body.
  • the same is in principle also possible with a rotatable base body, in which the stops in different angular positions of the rotatable base body are optionally also arranged with the same or different lengths.
  • the stops are arranged at different distances from the processing tool in order to realize a format change in the otherwise gleichspawn inventive woodworking machine in a simple manner.
  • the base body is rotatable or longitudinally movable, in particular at right angles to the support surface can be raised or lowered. All of these different variants serve to move the base body with the stops arranged thereon out of the support surface or, conversely, to position the stops in the support surface in the same way. According to the invention it is also provided that, for example, the stops project upwards, but each have a different effective length.
  • the stop system can be lowered so that the respectively suitable for processing stop is positioned in the support surface.
  • the support table are arranged, and which are then arranged at different altitudes, in each case the altitude is to be controlled, the stop width of the respective stop is just needed.
  • the base body allows in a simple manner positioning all attacks to size.
  • the various stops are arranged at fixed distances from each other on the base body. Moving the body thus positioned the selected stop in a simple and easy to use. The same body is used with the same adjustment for the dimensionally accurate setting of all other stops when they are selected.
  • the lowering or raising of the stops with respect to the support surface takes place according to an advantageous embodiment parallel or perpendicular to the support surface of the support table. This ensures that always an exact positioning of the workpieces can be done on the abutment edges, whereby the dimensional accuracy is increased or guaranteed overall.
  • Known from the prior art solutions are either not lowered into another plane or only by pivoting a stop with a plurality of stop surfaces, which is mounted on a shaft.
  • this solution results in that the stop is then no longer adjustable at right angles to the support surface, so that the now proposed solution of the parallel or rectangular lowering of the stops with respect to the support surface solves this problem elegantly.
  • a plurality of stops are arranged on at least one base body, such that the stop which has the smallest distance from the machining tool, in the lowest altitude in relation to the working plane and the stop with the greatest distance to the machining tool in another , then the highest Altitude is arranged in relation to the working plane. It is therefore provided, for example, a stair-step-like design of the individual stops on the base body, wherein the individual stops are arranged in increasing altitude, the farther the stop is removed from the machining tool, the higher the altitude in which it is arranged.
  • Another aspect of the stop system according to the invention is specified by the fact that a plurality of base body are provided, whose distance relative to the machining tool is adjustable or adjustable. On the one hand is ensured by this embodiment, that the distance between the base body relative to the machining tool can be adjusted, on the other hand, it is further ensured that, for example, several basic body with several, arranged there stops, for example, can be arranged at the same distance from the machining tool. Of course, then an arrangement of the respective desired stop in the desired altitude is possible.
  • At least two main body are adjustable by a common adjustment in their distance from the machine tool.
  • the main body By coupling the main body by means of a common adjustment system, the adjustment of the desired workpiece width is facilitated overall. This makes the stop system according to the invention even more comfortable.
  • a lowering device for lowering at least one main body.
  • a lowering device can then be adjusted via a respective actuator, the respective desired altitude of the body and thus the respective desired stop.
  • a plurality of base body can be lowered or raised via a common lowering device in different altitude. This is particularly advantageous if the stops or base body are arranged parallel to each other, so that a longer workpiece can be applied to corresponding attacks of several bodies simultaneously.
  • the stop system according to the invention is characterized in that at least three altitudes can be adjusted by means of the lowering device.
  • the spaced apart with the smallest distance from the machining tool side of the body is a first stop.
  • a second stop can then be arranged further spaced apart on the base body in a higher altitude.
  • three altitudes can be realized in total.
  • the lowering device for the main body has a lowering mechanism which is designed as a toggle mechanism with knee levers which are adjustable via joints and at least one additional latching position.
  • the lowering mechanism can be operated via an operating element. Due to the execution of the toggle mechanism with corresponding locking positions, the altitude for the respective attack to be controlled is always selected exactly. This is a simple but very effective embodiment of the stop system according to the invention.
