Embodiment Construction

[0022] figure 1 A schematic longitudinal section through a closing unit 1 of a closing machine for closing containers (not shown) with a closing element 2 is shown. The closing unit 1 according to the illustrated embodiment is designed for aseptic operation and comprises a closing wall 3 of the closing machine which separates the clean room region RR from the Gray room GR. The partition wall 3 divides the sealing unit 1 into a driving part 4 and a sealing tool 5 .

[0023] to combine figure 2 It can likewise be seen that the closing tool 5 comprises a housing 6 in which a holding device 7 is accommodated. Preferably, the holding device 7 is accommodated in the housing 6 replaceably and can be replaced for handling different closures. In particular, if the design is intended for aseptic operations, these component parts fit seamlessly in a sealed manner.

[0024] In the illustrated embodiment, the gripping device 7 comprises a plurality of gripping members 8 in the form of...

Abstract

A closing tool for a closing machine for placing a closure on a container, where a holding force is applied to the closure by means of a gripping device. In order to obtain a universal embodiment for the closing tool the gripping device is provided with a magnetic actuator, such as with permanent magnets, for applying the holding force.

Description

technical field [0001] The invention relates to a closing tool of the type described below: a closing tool for use in a closing machine to provide a closure to a container, said closing tool comprising gripping means for applying a holding force to said closure. Background technique [0002] A closing tool of this type is known from WO2004 / 009484. The known sealing tool comprises a holding device formed with a plurality of holding tabs grouped in a ring around a center line. In use, the centerline coincides with the centerline of the container. The clips can approach and move away from the centerline within a limited range. This embodiment serves to compensate for the small tolerances that may occur on a regular basis even if the production of the closures is carried out with the greatest care, thereby reducing the error rate of closures that cannot be screwed on. To this end, the clamping tab is received radially displaceably towards the center line in the holder and is ...
