Abstract
A welding installation with a calibration tool is provided in a device for producing container shells. The force exerted by the container shells on the calibration tool is measured and evaluated as information for the overlapping width of the respective container shell. This allows adjusting the calibration tool during configuration of the device and allows the removal of container shells welded with too large or too small overlapping during production of container shells.
Claims19
A method for producing container shells, wherein rounded shells are transported from a transport installation to a roll seam welding machine and the shells pass through a calibration tool with a plurality of calibration rollers arranged in a wreath-like way before the welding rollers of the roll seam welding machine, wherein a measurement of the force exerted by the respective shell onto at least one calibration roller of the calibration tool is performed, wherein the measured force is evaluated as information for the overlapping width of the shell.
A device for producing container shells, comprising a transport device for transporting rounded shells and a roll seam welding machine, in which the blanks with overlapping edges are welded by means of welding rollers of the roll seam welding machine, wherein the device has a calibration tool with a plurality of calibration rollers arranged in a wreath-like way, which is arranged in transport direction before the welding rollers of the roll seam welding machine, and which has force measurement installation, by means of which a measurement and evaluation of the force exerted by the respective shell on the calibration roller is carried out at least a calibration roller, wherein a signal reflecting the measured force is generated by the force measurement installation, and in that the signal is evaluated in the device as information for the overlapping width of the shell.
A calibration tool for a production installation for roll seam welded container shells, wherein the calibration tool has a plurality of calibration rollers arranged in a wreath-like way, and a force measurement installation for measuring the force exerted by a container shell passing through the calibration tool onto at least one of the calibration rollers, wherein a signal reflecting the measured force is generated and output by the force measurement installation, or wherein a signal derived from the measured force is output by the force measurement installation.
