Definitions

  • the invention relates to an end profiling machine for frame wood for window frames, with a first working unit for profiling the one frame wood end, which has a first work table with a clamping device, which can be moved past a crosscut saw from its starting position transversely to the longitudinal direction of the frame wood and at least one cutter set, with one of the first Working unit downstream, similar second work unit for profiling the other frame wood ends, which has a second work table that can be moved parallel to the first work table, with a feed conveyor, by means of which the frame timbers can be fed in their longitudinal direction to the first work table in its initial position, with a conveyor, by means of which the frame timbers can be conveyed away from the second work table in their longitudinal direction, with a table conveyor assigned to each work table, by means of which the frame timbers in their L longitudinal direction on the respective working table are movable and, if appropriate, as well as associated with a provided between the two working tables, transfer conveyor, by means of which the frame timbers can be conveyed in its longitudinal direction from the first
  • Such a known end profiling machine (see company brochure from Hemag, Heidelberg, "THE BIG HEMAG PLANT"), is integrated in a system for the automatic frame-by-frame production of windows.
  • the end profiling machine is used to provide the frame wood, which is usually supplied in pairs, on both sides with pins and slots.
  • the two work units are two similar so-called tenoning and slitting machines, whose cross-cut saws and cutter sets are arranged opposite each other so that the first end of each frame wood is first provided with tenons and slots, then moved in its longitudinal direction on the work table of the second unit against its adjustable length stop and is profiled by the cutter set of the second work unit at its second end.
  • the above-mentioned known end profiling machine and also end profiling machines from other manufacturers are designed so that the first work table of the first work unit with the frame members clamped on it passes from its initial position to the crosscut saw and the milling cutter set, the frame wood being profiled at one end.
  • the work table reaches its end position, in which it is aligned with a longitudinal conveyor.
  • the frame timbers are then conveyed onto the second work table of the second work unit which is in its starting position. In its end position, the first work table is aligned with the second work table in the starting position.
  • the frame timbers After the frame timbers have reached the length stop, they are clamped onto the second work table by means of the clamping device and then moved past the cross-cut saw and the cutter set of the second work unit by forward movement of the second work table and thus profiled at their second ends. At the end of the forward movement, the second work table reaches its end position in which the clamping device is released. The frame timber profiled on both ends can then be transported away from the second work table by means of the conveyor. While moving forward At the end of the second work table, the first work table returns empty to its starting position and is then loaded by the feeder with a new pair of frame members, whereupon a new work cycle can begin.
  • the second work table in its end position can be unloaded, however, the transfer of the frame timbers from the first work table which was in its end position after a part of a work cycle to the second work table in its starting position requires a certain amount of time which extends each work cycle.
  • a transverse transport device which moves each frame timber transversely to the two conveyor belts against an adjustable stop. After this has been done, each frame timber is clamped back onto the drivers.
  • the conveyor belts move further forward, the other ends of the frame timbers are each moved past a second cross-cut saw and two second cutter sets, the other conveyor belt on the outside of the are arranged. In this way, each frame wood is profiled at its second end. After this has taken place, the frame members profiled at both ends are delivered to a transport device running transversely to the conveyor belts.
  • this known woodworking machine is relatively expensive to construct. The machining accuracy is also low.
  • Another known end profiling machine (DE 33 03 162 A1) has two stationary work tables which are arranged at some distance from one another and whose longitudinal directions are aligned with one another. Likewise, a feed conveyor and a removal conveyor are arranged in alignment with the two work tables on a common escape axis. A trolley with two circular saws and two sets of milling tools can be moved across the work tables between the two work tables. When the carriage is moved, the front ends of the frame members clamped on the first work table and the rear ends of the frame members clamped on the second work table are machined.
  • the invention is therefore based on the object of providing an end profiling machine for frame timber for window frames of the type mentioned at the beginning, in which the cycle time of a work cycle is shortened without additional mechanical outlay and without acceleration of the individual work processes and which therefore has a higher output.
  • the two work tables are aligned in their initial positions in their longitudinal directions, that the longitudinal direction of the conveyor is aligned with the longitudinal direction of the second work table in its initial position, that the first work unit with its cross-cut saw and its cutter set arranged on one side of an escape axis running through the feed conveyor, the conveyor and the two work tables in their starting positions and the second work unit with its cross-cut saw and cutter set on the opposite side of the escape axis, and that the two work tables in opposite directions from theirs Starting positions can be moved into their end positions, such that both work tables can be moved back to their starting position together with the frame members clamped thereon after the end profiling and there nn in the case of work tables in the starting position, both-sided profiled frame wood from the second work table to the conveyor, single-ended frame wood from the first work table to the second work table and frame wood, the two ends of which are not yet profiled, from the feed conveyor to the first work table along the common one Escape axis are movable.
  • the invention is therefore based on the idea of arranging the two work units in relation to one another in such a way that the two work tables are aligned with one another in their starting positions.
  • the invention then proceeds from the idea of having the frame timbers stretched out on the work tables after they have been profiled at their ends by the respective work unit and each work table has reached its end position, and then returned to the starting position together with the work tables. Only when this has been done is the single-ended profiled frame timber transferred from the first work table in its initial position to the second work table also in its initial position.
  • the first work table is simultaneously loaded with a new pair of frame timbers by means of the feed conveyor, and the frame timbers profiled on both sides are moved away from the second work table by means of the away conveyor.
  • each work table from its starting position to its end position can be shorter than with the previous end profiling machines. So far, namely, at least the first work table had to be moved beyond the actual processing stations into the area of the transfer conveyor which was arranged on the longitudinal side of the machine outside the actual work unit. With the new end profiling machine, on the other hand, the work tables can be put back in immediately after the frame timbers spanned on them have passed the milling cutter set or after an additional processing station for milling the miter of the glass retaining strips their starting position are moved back.
  • the work output is about 30% higher. Since the work units are arranged on opposite sides of the escape axis, the two work units cannot interfere with one another in terms of space. As a result, their work tables can be arranged very close to each other in their longitudinal direction or in the direction of the escape axis, ie the direction of movement of the frame timbers. This results in very short transfer paths, which further shortens the cycle time required for a work cycle. In addition, an over conveyor between the two work tables may not be necessary, but at least this can also be made very short.
  • the end profiling machine according to the invention has the further advantage that two completely identical, standard working units and conventional feed and removal conveyors can be used for its construction. This results in lower manufacturing costs. In addition, both work units only work with right-hand milling tool sets, so that there are lower costs for the procurement and storage of the tools. (Continued as on pages 6-10 of the original description.)
  • Such a transfer conveyor If such a transfer conveyor is provided, then it must be arranged so that it is aligned with the longitudinal direction of the first work table in its initial position.
  • the drawing shows a schematic top view of the end roll forming machine.
  • a first work unit 1 for tenoning and slitting has a rectangular work table 3, which can be moved transversely to its longitudinal direction from its starting position A, which is shown in full in the drawing, in direction B into an end position E, shown in broken lines.
  • the work table 3 is provided with a clamping device 4, by means of which a pair consisting of two frame frames R lying next to one another can simultaneously be clamped on the work table 3.
  • the work table 3 is further provided with an endless conveyor belt 5 extending in its longitudinal direction, by means of which the frame members R2 can be moved along the work table 3 in their longitudinal direction.
  • the work unit 1 also has a crosscut saw 6 and one or more cutter sets 7 which are mounted on vertical spindles 8.
  • the working unit 1 can also be provided with a device, not shown, which processes the part of the frame timber which is later intended for the glass retaining strip, in terms of length and miter. Such a device is described for example in German patent 29 21 202.
  • the first work unit 1 is followed by a second work unit 2, which corresponds exactly to the first work unit 1, with the only difference that the second Working unit 2 is arranged rotated by 180 ° in a horizontal plane with respect to the first working unit 1.
  • This second work unit 2 has a work table 3 ', which is referred to in the following as a second work table.
  • the remaining parts of the work unit 2 which correspond to the parts of the work unit 1 are identified by the same reference numerals, with an index line being added to differentiate the parts of the second work unit 2.
  • the above description of the first work unit 1 applies analogously to the second work unit 2.
  • the second work table 3 ' is also provided by means of an actuator in the longitudinal direction of the work table 3' adjustable length stop 9 which is electronically adjustable in accordance with the predetermined length dimension of each of the second work table 3 'to be machined frame R.
  • a feed conveyor 10 is also arranged in front of the work table 3 of the first work unit 1 and is aligned with the longitudinal direction of the work table 3 in the starting position A.
  • a conveyor 11 is arranged which is aligned with the longitudinal direction of the second work table located in the starting position A.
  • a transfer conveyor 12 may also be arranged, which is aligned with the longitudinal directions of the two, in each case in the starting position A work tables 3, 3'. The transfer conveyor is only required so that very short frame timbers can also be properly brought from the first work table 3 to the second work table 3 '.
  • the two work units 1, 2 are arranged so that the two work tables 3, 3 'in their starting positions are aligned in their longitudinal directions, so that when both working tables 3, 3' are in their starting positions, frame members in their longitudinal direction of the first work table 3 can be moved via the transfer conveyor 12 to the second work table 3 '. If necessary, it would also be possible to arrange the two work tables 3, 3 'so close together that the transfer conveyor 12 can be omitted.
  • the first work unit 1 with its cross-cut saw 6 and its cutter sets 7 is arranged on one side of the escape axis F, and the second work unit 2 with its cross-cut saw 6 'and its cutter sets 7' on the opposite side of the escape axis F.
  • the new end roll forming machine works as follows:
  • the feed conveyor 10 conveys a first pair of frame members R in their longitudinal direction L onto the first work table 3, the conveyor belt 5 of which moves the frame members against the fixed stop 13.
  • the feed conveyor 10 brings a second pair of frame members R to the waiting position in front of the first work table.
  • the clamping device 4 clamps the two frame timbers R located on the work table 3 there and this moves from its starting position A in direction B.
  • the frame timbers are first guided past the crosscut saw 6 and cut off there at right angles.
  • the frame timbers are profiled by one of the cutter sets 7 at one end, ie provided with pins and slots there.
  • the first work table 3 has reached its end position E, it moves back to its starting position A with the frame members stretched against the direction of the arrow B.
  • the clamping device 4 is released and the stop 13 is pivoted or pushed away.
  • the feed conveyor 10 the transfer conveyor 12 and the conveyor belts 5 of the two work tables 3, 3 'in motion.
  • the frame timber R profiled at one end is brought from the first work table 3 to the second work table 3 'and moved there against the length stop 9 which was previously electronically set.
  • the second pair of frame timbers runs onto the first work table 3 against the stop 13.
  • a third pair of frame timbers is also moved simultaneously from the first work table 3 in the waiting position.
  • the result is in the drawing presented situation.
  • both work tables 3, 3 'move in opposite directions B, C, with the cross-cut saw 6' and the cutter sets 7 'of the second work unit the frame woods of the first pair located on the second work table are profiled at their second ends.
  • the frame timbers on the first work table are profiled at their first ends.
  • the feed conveyor 10 the two conveyor belts 5, 5 'of the work tables 3, 3', the transfer conveyor 12 and also the conveyor 11 are simultaneously set in motion in the same direction L.
  • the feed conveyor 10 the two conveyor belts 5, 5 'of the work tables 3, 3', the transfer conveyor 12 and also the conveyor 11 are simultaneously set in motion in the same direction L.
  • four pairs of frame timbers are moved at the same time, namely that both ends profiled first pair from the second work table 3 'on the conveyor 11, the one end profiled second pair from the first work table 3 to the second work table 3', the non-profiled third pair from the feed conveyor onto the first work table and a fourth pair is brought into waiting position in front of the first work table 3 by the feed conveyor 10.
  • the simultaneous further movement of several frame timbers in a straight line significantly shortens the cycle time for a work cycle.
  • Window frames are understood to mean both window frames (casings) and casements.
