Definitions

  • the invention relates to a method for bending from hollow profile strips to spacer frames for insulating glass panes.
  • Devices for bending hollow profile strips to spacer frames are for example from the DE-GM 87 05 796.4 or DE-OS 32 21 986 known.
  • the Length of the profile bar protruding beyond the bending point can be determined so that the Spacer frames with the desired dimensions is obtained.
  • the known bending devices for manufacturing a spacer frame for insulating glass panes determine the length of the profile bar Path measurement via incremental encoder.
  • the hollow profile strip is attached to it transport rollers lying on both sides moved by which is driven at least one.
  • an impeller encoder wheel
  • the hollow profile strip transported in this way rolls an impeller (encoder wheel), which over the axis or other drive with an incremental encoder is non-positively connected.
  • the encoder wheel which is on the outer wall rolls along the hollow profile bar, detects the feed the hollow profile strip.
  • Devices for bending are also known of hollow profile strips, especially for bending Hollow profile strips for spacer frames for insulating glass panes, with two on the side faces of the to bending hollow profile bar attachable jaws, one Abutment around which the hollow profile strip is bent and a bending lever opposite the abutment can be pivoted to carry out the bending work is.
  • Such bending devices in part as possible sharp-edged bends in the hollow profile strips are intended to result in different embodiments known.
  • DE-PS 32 23 881 DE-GM 87 05 796 or the US-PS 4,836,005.
  • Spacer frames and devices for manufacturing the same are from FR-PS 2 449 222 and DE-OS 32 21 986 known. It is still to refer to DE-OS 33 12 764, from which it is known is, hollow profile strips to spacer frames bend for insulating glass panes, being in the area the bending point from the inside against the hollow profile strip attachable mandrel is provided. The bending is done by swiveling one cheek, the other End of the profile bar between a movable Jaw and one from the inside of the Profile bar abutting abutment is clamped.
  • a problem with the known bending devices is that for use with insulating glass panes required sharp-edged turns in the area of the corners of the spacer frame cannot always be easily reached because partly there is a risk that the walls of the hollow profile strip tear during the bending process and the side surfaces the hollow profile strips in the corner area, i.e. not always flat where they have been bent run, but have corrugations that the subsequent processing of the spacer frame, especially the coating of its side surfaces difficult with sealant or adhesive and hinder.
  • DE-AS 21 28 717 describes a method for Apply a metallic spacer to the Slice edges of one of the rectangular glass plates an insulating glazing known in which the spacer as a continuous strip with a parallel disc Surface of a first pane edge the horizontally lying glass plate and then attached to this surface as well as the continuous spacer on one disk-parallel surface of the next disk edge brought into contact and then on this surface is fixed, whereupon the consequence of the previous Steps in the following Disc edges are repeated, followed by the spacer is cut off and its ends joined together will. This is how this procedure works proceeded that the glass plate after attaching of the spacer on one edge of the pane, however before pivoting, parallel to this Edge of the pane by a length corresponding to it Route is moved.
  • the pivoting of the Glass plate takes place around a fixed Swivel axis, with the spacer around this pivot axis is bent.
  • the Spacers initially only over part of the length of the first edge of the pane and the spacer after its attachment to the disc parallel Area of the last pane edge with er cut off a supernatant. Only then will the protruding part around the pivot axis of the glass pane bent by 90 ° and attached to the glass pane.
  • AT-PS 360 311 is the bending of spacer frames from one to the required length cut hollow profile known.
  • the AT-PS 360 311 is no indication that the hollow profile strip only after bending three Corners of the spacer frame to be manufactured cut from the supplied hollow profile strip shall be.
  • EP-A-318 748 discloses a bending device described, primarily on the design a bending tool is referred to.
  • the clamping device for detecting the before Bending area of the section of the hollow profile strip is not in the feed direction in EP-A-318 748 the hollow profile strip is movable. It therefore serves also not for conveying the hollow profile bar. Special Measures or devices for advancement the hollow profile strip between the bending processes are also not mentioned in EP-A-318 748 like the measure, the hollow profile strip only after the third bending process from the supplied hollow profile bar cut off.
  • EP-B-249 946 bends two corners out of one at a time already cut to length. From EP-B-249 946 is the deflection of the ends the hollow profile strip from the bending plane itself known. The bending process of EP-B-249 946 but deviates from the method mentioned at the beginning since the latter does not have two corners at the same time getting produced.
  • the object of the invention is to provide a method for To make available, during which transport the length of the hollow profile strip in a bending device the advance of the hollow profile strip exactly and without Tolerances is measurable.
  • Length for example, the maximum stroke

So can the hollow profile strip when bending the last corner are kept safe.
  • the advance is accurate because of the hollow profile strip during the movement of the feed device in their starting position in the area of the bending point is held.
