Abstract

A device (1) for the handling of containers with a mandrel (4), the cross-section of which is adjusted to the cross-section of one of the containers to be handled, whereby the mandrel (4) is displaceable, relative to the support device (30), along a direction of movement (L) between a resting position and a working position. The device has a spacing element (10) which is displaceable relative to the mandrel (4) in a direction of displacement (R) between at least two positions, whereby the direction of displacement (R) and the direction of movement form an angle with one another that differs by 0°, and whereby this spacing element is constructed in such a manner that the working position of the mandrel (4) in the direction of movement (L) is changed through a shifting of the spacing element.

Claims

1. A device (1) for the handling of containers (20), comprising a mandrel (4), the cross-section of the mandrel (4) being adjusted to the cross-section of a container to be handled (20), the mandrel (4) being displaceable relative to a support (2) along a direction of movement (L) between a resting position and a working position, a spacing element (10) which is displaceable relative to the mandrel (4) in a direction of displacement (R) between at least two positions, the direction of displacement (R) and the direction of movement (L) forming an angle with one another that differs by 0°

, and the spacing element (10) being constructed in such a manner that the resting position of the mandrel (4) along the direction of movement (L) is changed by a shifting of the spacing element (10).

2. A device (1) in accordance with claim 1, wherein, the spacing element (10) is displaceable in a direction proceeding essentially perpendicular to the direction of movement (L).

3. A device (1) in accordance with claim 1, wherein the spacing element (10) has a fork-shaped spacing body (12).

4. A device (1) in accordance with claim 1, wherein the mandrel (4) is positioned rotatably around its axis (A), whereby the spacing body (12) partially surrounds the shaft (6) in one position of the spacing element (10).

5. A device (1) in accordance with claim 1, and a guide bolt (14) is positioned on the spacing element (10), whereby the guide bolt (14) extends in the direction of movement (L).

6. A device (1) in accordance with a claim 3 wherein the spacing body (12) is positioned detachably on a displacement body (16).

7. Currently Amended A device (1) in accordance with a claim 3, and a first adjusting device (42) which is positioned, at least occasionally, between the guide bolt (14) and the spacing body (12).

8. A device (1) in accordance with claim 7, and a second adjusting device (44), and the spacing element (10) is positioned, at least occasionally, between the second adjusting device (44) and the shaft (6).

9. A device (1) in accordance with claim 8, wherein the first adjusting device (42) and the second adjusting device (44) are displaced laterally to one another in the direction of movement (L).

10. An apparatus for the handling of containers, including:

a device for the handling of containers comprising a mandrel having a cross-section being adjusted to the cross-section of a container to be handled, the mandrel being displaceable relative to a support along a direction of movement between a resting position and a working position; and

a guide rail that carries out a displacement of the device along a direction of displacement, the guide rail being movable in the direction of displacement.

11. An apparatus in accordance with claim 10, the device having a spacing element that is displaceable relative to the mandrel in a direction of displacement between at least two positions, the direction of displacement and the direction of movement forming an angle with one another that varies by 0°

, and the spacing element being constructed in such a manner that the resting position of the mandrel along the direction of movement is changed by shifting of the spacing element.

12. A process for the handling of containers (20), comprising inserting a mandrel (4), the cross-section of which is adjusted to the cross-section of the container to be handled (20), into the aperture of this container (20), at least in sections, and whereby the mandrel (4) is displaceable in a direction of movement (L) between a resting position and a working position, and changing the resting position if a spacing element (10) is displaced in a direction of displacement (R), whereby the direction of movement (L) and the direction of displacement (R) form an angle with one another that differs by 0°

.

13. A process, in accordance with claim 12, and controlling the movement of this mandrel (4) from the resting position into the working position with the help of a lead cam (35, 38), and the position of the lead cam (35, 38) relative to a stationary base is changeable in the direction of movement (L).
