## Abstract

Container clamp grip for a container transport system having two grip arms that can be swiveled about one or about two axles between a grip position and a release position, the two grip arms being applied with springiness in the direction toward the grip or toward the release position by a force storing unit presenting at least one pair of mutually repelling permanent magnets. The container clamp grip is controlled by a control cam. In the container grip position, a first air gap is provided between the permanent magnets, and in an extreme closed position of the clamp grip, if there is no container, a second, smaller air gap is provided between the permanent magnets.

## Claims

### Claim 1

Container clamp grip (K1, K2) for a container transport system, particularly for a bottle transport system, comprising two grip arms (7) which can be swiveled about one or about two axles (5) between a grip position and a release position, the two grip arms (7) being applied with springiness in the direction toward the grip position or toward the release position by means of a force storing unit, and the force storing unit presents at least one pair of mutually repelling permanent magnets (P1, P2), wherein the container clamp grip (K2) is controlled by a control cam which can be rotated between the extensions (7b) of the grip arms (7) which can be swiveled about separate axles (5) on a support plate (4), and can be held by the repelling force (F1, F2, F3), which acts in the direction towards the release position, between the permanent magnets (P1, P2), which are arranged on the grip arms (7) between grip areas (9) and the axles (5), with the extensions (7b) in contact with the control cam (21), wherein, in the container grip position, a first air gap (L1) is provided between the permanent magnets (P1, P2), and in an extreme closed position of the clamp grip (K2), if there is no container (B), a second air gap (L2), which is smaller than the first air gap (L1), is provided between the permanent magnets (P1, P2).

### Claim 2 (depends on 1)

A container clamp grip according to claim 1, wherein each permanent magnet (P1, P2) is cylindrical and accommodated in a capsule housing (12), which sits with a retaining foot (18) in a recess (19) on the inner side of the grip arms (7).

### Claim 3 (depends on 2)

A container clamp grip according to claim 2, wherein the retaining foot (18) is arranged adjustably in the recess (19).

### Claim 4 (depends on 2)

A container clamp grip according to claim 2, wherein the retaining foot (18) sits at the bottom of a recess (20) in the inner side of the grip arms (7).

### Claim 5 (depends on 1)

A container clamp grip according to claim 1, wherein one of compensation pressure spring pads (24), compensation leaf spring elements (23), or a combination thereof are provided between the extension (7b) and the control cam (21).

### Claim 6 (depends on 1)

A container clamp grip according to claim 1, wherein the force storing unit formed by the permanent magnets (P1, P2) acts directly between the grip arms (7).

### Claim 7 (depends on 1)

A container clamp grip according to claim 1, wherein the permanent magnets (P1, P2) of the pair are arranged approximately in the center between the grip area (9) and the axle (5).
