Definitions

  • the invention relates to a woodworking machine for tenoning and longitudinal profiling of window timbers with at least one tenoning and slot unit and at least one unit for longitudinal profiling, the tenoning and slot unit being assigned a roller table for guiding the window wood past the tenoning and slot spindles, a transfer device also being assigned is provided with which the window timbers to be processed are transferred to a longitudinal profiling unit at right angles and finally a rotating platform is provided for turning the window timber by 180 °.
  • the rotating platform is arranged in the area of the tenoning and slotting device in the workflow in front of the longitudinal profiling device, the Window wood is first led with its one end face past the tenon and slot spindles and, after the tenons and slots have been attached, transferred to the revolving stage, rotated there by 180 ° and, for the second time, the tenon and slot unit with pins and slots attached to it other end face.
  • the first arrangement with the additional longitudinal profiling unit has the disadvantage that, in addition to the additional costs, the machine becomes more voluminous and complex, while in the second arrangement it is disadvantageous that the counter-stop provided there is interruptions for the passage of the tools onto the Must have spindles, which can adversely affect the promotion of short window timbers in particular.
  • the invention is accordingly based on the object of designing a woodworking machine in such a way that a machine is produced which, in addition to a compact design, requires as few units as possible.
  • the revolving stage is arranged behind the longitudinal profiling unit in the workflow and that the window timbers provided on one side with pins and slots are transferred to the longitudinal profiling unit in this state, are longitudinally profiled there on one side, and are then conveyed to the revolving platform to be turned through 180 ° to run through the machine for the second time.
  • the other end face is accordingly provided with pins and slots and the side opposite the side already profiled is profiled lengthwise, since the window wood now passes through the machine in the turned state.
  • the arrangement according to the invention makes it possible, in particular, to design the longitudinal profiling unit in such a way that the counterstop is continuously formed there without interruptions, so that the disadvantage of obstructing the conveyance of short window frames does not exist.
  • the counterstop can be designed continuously because the longitudinal profiling of both sides of the window wood takes place from the same side, because the window wood is turned after the first pass through the longitudinal profiling unit.
  • the counter stop cannot be adjusted transversely in the longitudinal profiling unit, but the longitudinal profiling spindles are fed, because this makes it possible to start with the longitudinal profiling of the following wood while the end of the preceding wood is located in the longitudinal profiling unit. It is particularly advantageous here that the counterstop, because it is no longer moved, can be made relatively long, so that a larger number of spindles can also be provided in succession in the longitudinal profiling unit.
  • the infeed of the longitudinal profiling spindles is numerically controlled and if the dimension, that is to say the width, of the window wood is predetermined by the infeed of the longitudinal profiling spindles.
  • a numerical control has the advantage that it works much more precisely than the previously known width controls by means of the counter stop.
  • Another advantage is that such an arrangement enables several longitudinal profiling spindles of the longitudinal profiling unit to be used simultaneously, each of the longitudinal profiling spindles producing part of the profile.
  • regrinding of the tools does not lead to a new adjustment of the machine, since only a correction measure needs to be entered into the machine.
  • Another advantage of the arrangement according to the invention is that, in contrast to the known arrangement, the removal of the first window wood provided with pins and slots can be made into the longitudinal profiling unit, while the subsequent window wood is provided with pins and slots. Such a streamlining of the workflow is not possible with the known arrangement, because there the subsequent window wood must be turned and moved back.
  • a conveyor is expediently provided on the other side of the rotating platform, which transports the turned window wood back to the roller table.
  • the transfer from this conveyor to the roller table can be done manually or automatically.
  • the completed, i.e. Window wood provided with pegs and slots on both end faces and longitudinally profiled on both sides is expediently conveyed beyond the longitudinal profiling unit.
  • This promotion can also be carried out by an automatic switchover, which is expediently based on a program control.
  • the outfeed can be based on various known types of conveyors.
  • the axis of rotation of the rotating platform is expediently fixed between two conveyors arranged at a distance from one another, namely the conveyor from the rotating platform and the conveyor beyond the longitudinal profiling unit, the distance between the conveyors corresponding to the length of a horizontally arranged support which serves to hold the window frames and is turned by 180 ° in the horizontal plane.
  • Intermediate conveyors extend from the two conveyors to the horizontal support, which on the one hand convey the window timbers to the support and on the other hand these from the support.
  • the carrier of the rotating platform is lowered for the up and down conveyance.
  • the woodworking machine according to the invention is particularly advantageously suitable for simultaneously processing two equally long and similar window timbers, so that a complete window can always be completed.
  • a separating device of known type is expediently provided between the tenon and slot unit and the longitudinal profiling unit, which separates the two window timbers, which are provided with tenons and slots, so that these are successively, immediately adjacent to one another (joint to joint) can be promoted by the longitudinal profiling unit.
  • This promotion and processing butt to butt can only take place if the window frames are the same, ie if the longitudinal profiling unit does not have to be switched between two window frames.
  • the roller table can be moved back to its starting position and be reloaded for processing two next window timbers.
  • the longitudinal control can expediently take place by means of a known movable stop in front of the tenoning and slotting unit.
  • the tenoning and slotting unit is preceded by a cutting device in the form of a crosscut saw, which cuts off a preliminary measure on the end face of the window timbers facing it during the first pass of the window timbers, while the adjustable stop specifies the final length during the second pass.
  • the window wood can be brought to the system by hand or mechanically.
  • the arrangement according to the invention also makes it possible, in particular, to carry out the successive or simultaneous processing of the end faces of the window timbers in a cycle or in a continuous pass by replacing the roller table with a circulating belt, a chain with supports or the like.
  • Such a processing sequence which increases the throughput is excluded in the known arrangement because of the return of the window wood which is necessary there.
  • the machining of the face of a window wood on both sides is surprisingly possible, as is the profiling on both sides, whereby the same units can be used for both operations.
  • the additional tenon and slot units required in the known arrangements and the additional longitudinal profiling units are saved.
  • the machine according to the invention can therefore be manufactured much more cost-effectively than the known machines.
  • the figure shows a schematic representation of an embodiment of the woodworking machine according to the invention.
  • the woodworking machine has a pin and slot unit 1, which is associated with a roller table 2 in a known manner, which is shown in the figure in its two end positions, with a transfer device 3 connecting to the pin and slot unit 1, which a slide 4, with which the window timbers provided with pins and slots are fed to a separating device 5.
  • a pneumatic unit of the separating device 5 is designated by 6.
  • the window timbers are fed to a longitudinal profiling unit 8, in which a plurality of longitudinal profiling spindles 9 are provided, which can be set against the window timbers to be processed by means of a numerical control in the direction of the arrows 10.
  • the counterstop against which the window timbers during the longitudinal profiling process are held, is designated 11. This counter-stop is immovably arranged in the longitudinal profiling unit.
  • the longitudinal profiling unit 8 is followed by a turning device in the form of a rotating stage 12 which has a horizontally arranged support 13 which serves to hold the window frames and can be turned through 180 °.
  • the carrier 13 is rotated in the direction of the arrow 14.
  • the transfer of a lengthwise profiled window wood to the rotating stage 12 takes place with the interposition of a roller conveyor 15 via intermediate conveyor 16 and conveyor rails 17, the carrier 13 being in the position shown in the figure for receiving the window timbers, but being lowered in this.
  • the window timbers are fed via conveyor rails 18 to a further roller conveyor 19, which serves as a discharge conveyor and from which the window timbers are conveyed again onto the roller table 2.
  • the length control is carried out here by means of a stop 21 which can be moved in the direction of the double arrow 20, with one of the length and length units preceding the pin and slot unit 1 device in the form of a crosscut saw cuts the window timbers to the specified length.
  • the window timbers therefore pass through the woodworking machine according to the invention twice in the direction of the arrows 7, and after the second pass beyond the longitudinal profiling unit 8 there is a discharge in the direction of the arrow 23 via a conveyor 24, further processing units, for example a grinding machine 25, being able to be connected to the woodworking machine .
  • the window timbers to be processed are clamped on this side of the tenoning and slotting unit 1 on the roller table 2 and guided past the cross-cut saw 22, which cuts off a provisional measure on the end face of the window timbers facing it when the window timbers are first run through.
  • the window timbers are then guided past the tenoning and slot spindles 26 by means of the roller table 2 and thus their ends are provided with tenons and slots.
  • they are rolled tables 2 conveyed into a transfer device, which consists essentially of the slide 4, which feeds the window wood designated 27 to the separating device 5, in which they are separated from each other.
  • the window timbers then pass through the longitudinal profiling unit 8 one after the other and there are provided with longitudinal profiling on one side by means of the numerically adjustable longitudinal profiling spindles 9.
  • the window frames are then again in pairs on the lowerable carrier 13 of the rotating stage 12, whereupon this is rotated by 180 ° in the direction of arrow 14, so that the turned window frames on the intermediate conveyor 18 and one Abier 19 can be promoted to the roller table 2 for the second time.
  • the adjustable stop 21 now specifying the final length to which the window timbers are cut by means of the cross-cut saw 22. They are then provided with pins and slots on their other end face by means of the transfer device 3 fed to the separating device 5 and longitudinally profiled with the same units of the longitudinal profiling unit 8 on its second longitudinal side.
  • the roller table 2 can be replaced by an encircling belt, a chain with supports or the like, so that the processing of the end faces of the window timbers can be carried out in time or in a continuous pass.
