Problems solved by technology

[0005] As already mentioned, the disadvantage that arises in this case is that incorrect values ​​that do not correspond to the clamped pipe end may be entered by the operator, and the device still performs welding based on the incorrect values, which usually makes Soldering cannot be used

Embodiment Construction

[0028] figure 1 A schematic diagram of a device 1 according to the invention for carrying out the method according to the invention is shown.

[0029] At the clamping point 2 it can be seen that one of the pipe ends 3 is welded to the other, the other clamping point with the clamped pipe end is at the front of the view and is therefore not visible.

[0030] In the exemplary embodiment shown, the sensor 4 is arranged on the plane 5 . By controlled tilting of the plane 5 , which results in a defined tilting movement with respect to distance and speed, the sensor 4 is continuously moved along a predetermined curve 6 or radius.

[0031] At the level of the tube end 3, the sensor 4 senses the presence of the tube there and it is possible to determine which tube or tube size is clamped by measuring the duration of the sensor 4 sensing the tube and the speed of the tilting movement and the predetermined distance. Thus, the required welding parameters can be assigned, which are alre...

Abstract

Method for testing the ends of plastic pipes held in a butt welding machine, planed by means of a plane, which can be introduced between the ends of the plastic pipes and subsequently passed through Heating mirror heating, which can be introduced between the plastic tube ends and after removal of the heating mirror the plastic tube ends are welded together, the plane and / or the heating mirror are tilted into the plastic tube by a controlled movement Between the ends, wherein the detection or sensing of the plastic pipe ends during the controlled movement of the plane and / or the heating mirror tilting in is performed by at least one sensor arranged on the plane and / or the heating mirror.

Description

technical field [0001] The present invention relates to a method for inspecting the ends of plastic pipes held in a butt welding machine, planed by means of a plane that can be introduced between the ends of the plastic pipes, and a device associated therewith, and subsequently The plane and / or the heating mirror are tilted into between the plastic tube ends by controlled movement, heated by a heating mirror which can be introduced between the plastic tube ends and the plastic tube ends are welded together after removal of the heating mirror. Background technique [0002] Butt welding machines are used to join two plastic pipe ends, butt welding machines known in the prior art are generally manually actuatable, in particular the process of planing and heating the pipe ends. [0003] Previously, it was possible that the pipe parameters entered by the operator of the butt welder (which had to be manually entered into the machine for welding) did not correspond to the pipe ends...
