Device for welding continuously moving material web, has a sonotrode arrangement with a sonotrode tool and a counter holder cooperating with the sonotrode tool, where the sonotrode tool and the counter holder are separated through a column

摘要

The device comprises a sonotrode arrangement (2) with a sonotrode tool and a counter holder (3) cooperating with the sonotrode tool. The sonotrode tool and the counter holder are separated through a column and the material web to be processed is moved through the column on the sonotrode tool and the counter holder in a feed direction with a feed rate and is delivered for subjecting the material web with the sonotrode tool on a processing point of the tool and/or the counter holder. The sonotrode tool and/or the counter holder is movable along the moving web. The device comprises a sonotrode arrangement (2) with a sonotrode tool and a counter holder (3) cooperating with the sonotrode tool. The sonotrode tool and the counter holder are separated through a column and the material web to be processed is moved through the column on the sonotrode tool and the counter holder in a feed direction with a feed rate and is delivered for subjecting the material web with the sonotrode tool on a processing point of the tool and/or the counter holder. The sonotrode tool and/or the counter holder is movable along the moving web non-orthogonally running to feed direction of the material web, with a component directed in the feed direction of the material web for the processing point of the device. The sonotrode tool is arranged in a swing arm (7) through which a movement of the sonotrode tool between a first reversal point that lies in feed direction behind the processing point of the device, and a second reversal point that lies in the feed direction behind the processing point of the device. The sonotrode tool moves along a web curve curved in feed direction running to the counter holder from second reversal point to first reversal point and along a second web curve away from the counter holder from first reversal point to second reversal point. The wing arm is eccentrically arranged and is operated by a drive device that comprises an eccentric arrangement (9), which comprises an eccentrically arranged conrod element that is arranged at an axis and attacks with its end turned away the axis at the wing arm. The swing arm and the counter holder are arranged at a further axis and the counter holder is formed as a counter holder drum. The sonotrode tool is arranged over a shifting device in the swing arm.
