Definitions

  • the invention relates to a device for bending hollow profile strips to form spacer frames for insulating glass panes according to the preamble of claim 1.
  • Such devices are known for example from DE-GM 87 05 796.4 or DE-OS 32 21 986.
  • the length of the profile bar (hollow profile bar) projecting beyond the bending point must be determined so that the spacer frame is obtained with the desired dimensions.
  • the known bending devices for producing a spacer for insulating glass determine the length of the profile bar by measuring the distance via incremental encoders.
  • the profiled rod is moved by transport rollers resting against it on both sides, at least one of which is driven.
  • An impeller encoder wheel
  • the encoder wheel which runs along the outer profile wall, detects the extent of the advance of the hollow profile bar.
  • CH-PS 638 273 From CH-PS 638 273 a device for pressing insulating bars into metal profiles to be joined together to form a composite profile is known.
  • a longitudinal movement of the insulating rod is just as little caused by the jaws as in CH-PS 638 273 a movement of the jaws 26 applied to the insulating rod in the longitudinal direction is mentioned.
  • a pair of rollers is provided for moving the hollow profile strip.
  • the rollers cannot be moved in the longitudinal direction of the hollow profile strip.
  • transport rollers which are not mounted movably in the machine frame in the conveying direction, also serve for the advance of the hollow profile strip to be moved.
  • the invention has for its object to provide a device with which the length of the profile, i.e. the length of the profile during transport into a bending device. the extent of the advance of the hollow profile strip, can be measured precisely and without tolerances.
  • the hollow profile strip (profile bar) to be bent to the spacer frame is advanced by the gripper exactly before each bending operation by the distance which corresponds to the length of the respective leg of the spacer frame. If the length of the leg is greater than the maximum stroke of the gripper, the profile bar is advanced in two or at most more than two steps.
  • the procedure can be such that the first stroke (or the first strokes) corresponds to a predetermined length (e.g. the maximum stroke) and the last stroke is adapted to the length of the frame leg.
  • a structurally simple embodiment of the device according to the invention is characterized in that the gripper is provided on a carriage which is displaceable on a guide running parallel to the conveying device.
  • the extent of the movement of the slide for the gripper and thus the advance of the hollow profile bar can be determined particularly precisely and without great effort if it is provided that the drive motor for the slide has a displacement measuring device, e.g. an incremental encoder is assigned.
  • the carriage is coupled to an endless toothed belt driven by the drive motor.
  • the drive motor is mounted on the slide and has a pinion which meshes with a toothed rack which is fixedly mounted in the device.
  • the method of operation is simplified if a stop which can be lowered under the conveying device is provided at the bending point.
  • a hollow profile strip 3 is on a conveyor 4, which is arranged at the lower end of a support wall 10 and is, for example, an endless conveyor belt or a simple slideway, up to a stop 7 in the region of a bending point, consisting of a bending abutment 8 and a bending lever 9, which for the Bending the hollow profile bar 3 is pivoted, transported.
  • the device can also have, for example, the structure known from DE-GM 87 05 796 and have a support finger which can be adjusted up and down in the support wall 10 and which extends through the support wall 10, as is also the case in the known device according to DE-GM 87 05 796 is provided.
  • the hollow profile bar 3 is from the transport device 4 advanced at the lower edge of the support wall 10 to the end stop 7.
  • the hollow profile strip 3 is thus in a "zero" position without tolerance.
  • the jaws of the gripper 2 mounted on the slide 1 grip the hollow profile bar 3 in this position.
  • the end stop 7 is sunk into the conveyor track 4 and the carriage 1 with the hollow profile bar 3 clamped by the gripper 2 now moves in the direction of the bending lever 9 exactly by the distance that a process computer specifies and that corresponds to the length of the frame leg.
  • the bending lever 9 bends the section 3 ′ of the hollow profile strip 3 projecting beyond the slide 1, which moves upwards along the backward inclined support wall 10 at the angle specified by a process computer becomes.
  • the exact measurement of the distance traveled by the carriage 1 is determined by an incremental encoder 6 or the extent of the movement of the carriage 1 and thus the extent of the advance of the hollow profile strip 3 is controlled by the latter.
  • the incremental encoder 6 is mounted on the drive motor 5 or at another point on the movement path 4 of the carriage 1.
  • the carriage 1 is driven by an endless toothed belt and is guided on a guide running parallel to the conveyor track 4.
  • the engagement of the toothed belt in the drive gear of the drive motor 5 is exact and free of play, so that an incremental encoder 6 mounted directly on the motor-gearbox unit can also accurately register the distance traveled by the slide 1.
  • the effective distance to be traveled by the slide 1 corresponds to the length of the section 3 'of the hollow profile bar 3, which the process computer determines and the length of a leg of the hollow profile bar 3 to be produced by the bending processes Spacer frame corresponds.
  • the drive motor 5 does not need to be fixedly mounted on the bending table 10, but can also be arranged on the slide 1.
  • the drive gear of the drive motor 5 (geared motor) then engages in the toothed rack fastened to the guide 4, it being possible for an incremental encoder 6 to also be mounted on the drive motor 5 or on the slide 1.
  • the gripper 2 mounted on the slide 1 detaches from the hollow profile bar 3.
  • the slide 1 then moves back to its starting position (reference point) at high speed, and the gripper 2 is gripped the hollow profile strip 3 again frictionally.
  • the carriage 1 can again move in the direction of the bending lever 9 exactly by the distance specified by the process computer and move the hollow profile strip 3 accordingly.
  • the conveyor track 4 can be a simple slideway.
  • At least one gripper 2 is mounted on the movable slide 1, which is driven in a slip-free manner by a drive means 5 (geared motor), which grips the hollow profile bar 3 in a friction-locked manner.
  • the unit slide 1 and gripper 2 transports the hollow profile strip 3 in the direction of the bending lever 9.
  • the bending lever 9 presses the section 3 'of the hollow profile bar 3 against the bending abutment 8 (bending beam) as high as from the process computer is determined for the angle in the corner of the spacer frame that is to be bent.
  • the gripper 2 While the bending lever 9 presses the section 3 'of the hollow profile strip 3 around the bending abutment 8 by the predetermined angle, along the backward inclined support wall 10, the gripper 2 opens and the carriage 1 moves back into the starting position, after which the gripper 2 closes again and holds the hollow profile strip 3 frictionally. The carriage 1 then moves forward in the direction of the bending point 8/9 in accordance with the predetermined path length and the next corner can be bent.
  • FIG. 3 A particularly favorable embodiment of a gripper 2, which ensures the necessary frictional engagement for the precise advancement of the hollow profile strip 3, is shown in FIG. 3.
  • the movable jaw 12 can be pivoted behind the support wall 10 of the device so that it does not hinder the removal of a finished bent spacer frame.
