Description

 Device for transporting containers

The invention relates to a device for transporting containers according to the preamble of claim 1, in particular to a device for transporting containers in the form of bottles, preferably PET bottles.

A device for transporting containers with the features of

The preamble of claim 1 is the subject of German

Patent Application DE 10 2015 106 103 A1. This device comprises at least one transport element with at least one support section arranged thereon, on which at least one container gripper is provided for gripping and holding the container, wherein the container gripper has at least two pivotable gripper arms, which on the support section each have a pivot axis SA oriented parallel to the machine axis MA pivotable between a position engaging the respective container and a position releasing the corresponding container

are arranged. For this purpose, in DE 10 2015 106 106 A1, the gripper arms are each biased by at least one ironing or leaf spring-like spring element in a closed position and deflected for the pivoting movement against the spring force generated via the respective spring element in its open position.

Another container gripper is known from the German patent application DE 10 2014 1 17358 A1. In this container gripper, the two gripper arms are biased by provided on these arms spring tongues or spring arms in their closed position with a closing force, for which the spring arms in turn against a

Support locking element. This is movable relative to the spring arms such that the free ends of the spring arms in a position of the blocking element, which corresponds to a releasing state with a reduced closing force, a smaller

Have distance from one another than in a second position of the locking element, in which an increase in the closing force of the container gripper is achieved by increasing this distance and thus a locking state of the

Container gripper corresponds. Furthermore, container grippers (DE 10 2005 014 838 A1) are known, in which the closing force is achieved in that the gripper nose is formed integrally with rear, spring-elastic extensions. This has, inter alia, the disadvantage that the choice of material for the production of the gripper arms is severely limited. The respective control or locking element is an eccentric, against which the resilient rearward extensions of the gripper arms are supported and which must be rotated about an axis parallel to the pivot axis of the gripper arms for control between the locking state with increased closing force and the releasing state with reduced closing force.

Also known is a transport device (DE 10 2012 01 1 367 A1), which has a plurality of container gripper each having two gripper arms biased by spring force on a transport element which can be driven circumferentially around a machine axis. Each container gripper is associated with a closing element, which is cam-controlled for locking the gripper arms, movable radially to the machine axis and against the action of a return spring in a closed position in which the closing element engages over the two gripper arms like a rider and thereby against opening, i. against a moving apart blocks. So there is an actual positive locking of the gripper arms by the

Closing.

Also known are container gripper (DE 297 13 510 U), in which on a support plate pivotally mounted gripper arms are provided, which are biased by a compression spring in a closed position. The containers can be inserted via entry slopes on the front sides of the gripper arms under compression of the spring in one of the gripper arms and between them formed container receptacle and vice versa pulled out of this container receptacle again.

Also known is a container gripper (EP 2 279 143 A1), the gripper arms are inexpensive, easy and even without tools interchangeable. This is achieved in that a fixing element is positioned between the bearing ends of the gripper arms, wherein the bearing ends have an edge recess. By pivoting the gripper arms in an extreme opening position and by previously relaxing the one Closing force of the gripper arms generating tension spring, the gripper arms are released from the fixation, so that they are easily and without tools removed. Furthermore, a support body for attaching the respective container gripper on

Transport element deformable mounting tabs made of an elastic material.

The object of the invention is to show a device for transporting containers, which in particular also allows the most precise control movement of the container gripper with a simplified structural design. To solve this problem, a device for transporting containers according to claim 1 is formed.

The essential aspect of the device according to the invention for transporting containers is to be seen in that at least one to the machine axis MA radially slidable to initiate a positively guided pivotal movement of the first and second gripper arm of a corresponding container gripper

Slider element is provided, that the slide element has a first control cam for controlling the first gripper arm and a separate second control cam for controlling the second gripper arm, wherein the first and second control cam for positively guiding the respective gripper arm between the gripping and the releasing position is formed and the first and second gripper arm each having at least one engagement element which engages in the corresponding first and second control cam for positively guiding the two gripper arms. Regardless of the particular training in detail results for the

Device according to the invention or the container gripper according to the invention a large number of advantages. Thus, the container gripper and its gripper unit, in particular in the cross-position of the container (GP) and the corresponding container releasing position (FP) laterally spring over elastically formed cams and thus u.a. also possible

 Pitch distortions, i. Deviations in the pitch of container grippers or container receptacles and tolerances with respect to the synchronicity of

Balance container transport elements. For a safe transfer of containers between transport elements and / or transport stars, it is particularly important in rinsers, fillers or closers that held on the container grippers a transport element container as closely as possible have the predetermined pitch from each other, which is guaranteed despite the elasticity.

The movement of the locking elements of the container gripper between the blocking and the releasing state is preferably controlled via a respective driver cooperating with at least one control cam or via a corresponding cam roller. Here, the container gripper according to the invention is preferably designed so that each reached with a portion of the control cam position of the locking element and thus the corresponding state of the container gripper is maintained even without control curve, namely

in particular, the locked state of the container gripper, and that until a further portion of the control cam acts on the blocking element. As a result, short cams are possible, which reduce the design effort, wear and the manufacturing costs and the cleaning of the corresponding

Facilitate transport device or container handling machine. The container gripper according to the invention further allows a tool-free, simple and quick replacement of its functional elements, in particular also entire assemblies and wearing parts. Furthermore, the
