Description

The innovation relates to a device for closing Vessels with closures, preferably plastic closures with a Hollow plug. In order to increase the performance of closing machines, plastic closures in particular have been processed with an obliquely downwardly protruding tear-open flap has already been proposed, the closures on a preferably tsngential in the closing circle or an atonement that points over time aligned over the vessels, whereupon the presorted urvj downwardly repellent tear-off tabs against the vascular opening and are pulled by this under the sealing stamp.

The immediate entrainment of the closures from the vessels, however, leaves only a relatively low removal rate of closures.

Proceeding from the above-mentioned procedure, the object of the innovation is to create a device for closing vessels that is adapted to the requirements of today's high-performance machines, in particular for closures with hollow stoppers.

According to the invention, this object is achieved in a sealing machine ■ it υβ a vertical axis rotating and in the direction of its own

Axis up and down along a cam track closure elements and with one between the closure elements and The vessel end of the jj transfer device for the closures is achieved in that the closure transfer device is formed from at least two closure feed paths pointing tangentially into the closure turning circle, which in a descending curve shape of the Closing elements are arranged one behind the other at a decreasing distance from the vessel to be closed.

In this way a considerable increase in performance is achieved A sufficient supply of the closure to the closure elements is guaranteed regardless of the sorting works, which are limited in their performance. In addition, merging multiple channels is what is associated with considerable difficulties, especially in the case of plastic closures, is not required.

In a further embodiment of the invention it is proposed that the Closing elements have a driver pin which is coaxially enclosed by closer parts and guided in this, the free part of which by moving in the direction of rotation to the axis of the locking element, gripping jaws provided with a support surface.

It is also proposed according to the invention that the locking elements have alternating driving pins of different lengths, the locking elements with long driving pins being assigned to the locking feed track arranged at a higher level.

According to this embodiment, the closures located in the closure transfer device of the feed path located at a higher level are removed from the closure transfer device by the closure elements with longer driving pins and, as they slide further along the guide path, the Kleanbacken grips underneath them.

At the transferring part of this second locking device, the driving pin pushes into the hollow plug of the locking device that remains in the transfer position, which is now also gripped under by the small hooks and locked in its position.

As soon as the locker moves further downwards into the area of a vessel centered underneath, the clamping jaws spread by the vessel itself, as a result of which the closure is pushed into the mouth of the vessel by the driver pin. With further Rotation of the closing elements around the axis of the closer the vessel is finally closed.

Further features of the invention emerge from the description, the Claims and the drawings.
