Abstract
Transport star for containers with a basic body which can rotate, on whose circumference several gripper arms, in the form of double levers, are attached in bearings, which can be locked by selflocking in the closed position by means of spreader bodies which are arranged in the basic body so they can rotate. Each gripper arm consists of two parts which are connected to each other by articulation, between which a spring element is inserted, which can be elastically deformed in the closed position. As a result the duration of use of the gripper arms is increased and the range of diameters for the containers to be processed is considerably increased.
Claims13
A transport star for containers comprising in combination a basic body which can rotate, a plurality of gripper arms swingably mounted at the circumference of said basic body, said gripper arms formed as two-arm levers, the ends of said gripper arms pointing outwardly from an axis of rotation of each of said gripper arms, gripper surfaces provided on said gripper arms for the containers, the distal ends of said gripper surfaces pointing radially inwardly toward said axis of rotation of each of said gripper arms, counter surfaces provided for spreader bodies which are attached, in a manner so they can be moved, in said basic body, where said spreader bodies latch said gripper arms in a closed position, which is self-supporting, and which holds the containers to be grabbed, each of said gripped arms (4, 5) having at least two parts (4a, b;
- 5a, b) which are connected by means of an articulation to each other, each of said two parts bears one of said gripper surface (6) and said counter surface (7), at least one spring element(9, 9a) engages on said at least two parts (4a, b;
- 5a, b), said spring element elastically deformed in said closed position of said gripper arm (4, 5), and said spreader bodies being controlled by an actuator.
