Device for gripping and holding containers
A gripping-and-holding device for gripping and holding containers has a support body, pivotable spring-loaded gripper arms on the support body, three securing elements, two of which are on the gripper arms, and a traction spring that exerts a force towards a center defined between its first and second spring ends. The first two securing elements secure the traction spring. Meanwhile, a first end of the third securing element engages the traction spring outside its spring ends. Its second end is arranged on the support body.
1. An apparatus for use in a container-treatment plant having a transport element for transporting containers, said apparatus comprising a gripping-and-holding device for gripping and holding said containers, said gripping-and-holding device comprising a support body, pivotable spring-loaded gripper arms, first and second securing elements, a third securing element, and a traction spring, wherein said traction spring comprises first and second spring ends, wherein said support body is configured to be fixed to said transport element, wherein said support body comprises said pivotable spring-loaded gripper arms, wherein said first and second securing elements secure said traction spring, wherein said traction spring exerts a force in a closing direction, said closing direction being a direction towards a center of said spring, wherein said securing elements are arranged on said gripper arms, wherein said third securing element comprises a first end that engages said traction spring between said spring ends, a second end arranged on said support body, a head bar and a main bar that intersect said main bar.
2. The apparatus of claim 1 , wherein said third securing element comprises an engaging section on said head bar, and wherein said engaging section is rounded.
3. The apparatus of claim 1 , wherein said third securing element comprises a receiving section, and a hood-type recess, wherein said receiving section is on said head bar, and wherein said hook-type recess is arranged in said receiving section.
4. The apparatus of claim 1 , wherein said head bar is between two windings of said traction spring.
5. The apparatus of claim 4 , wherein said two windings are at the middle of said traction spring.
6. The apparatus of claim 1 , further comprising an insertion groove, wherein said insertion groove is on said main bar.
7. The apparatus of claim 1 , wherein said third securing element comprises an underside, a hook-type recess, and an insertion groove, wherein said hook-type recess is on said underside, wherein said hook type recess is arranged on said head bar, and wherein said insertion groove is on said main bar.
8. The apparatus of claim 1 , wherein said third securing element comprises a plate.
9. The apparatus of claim 8 , wherein said third securing element comprises a spring plate, and wherein said spring plate is made of steel.
10. The apparatus of claim 1 , wherein said third securing element is made of a plastic.
11. The apparatus of claim 1 , wherein said spring ends comprise spring eyes.
12. The apparatus of claim 1 , wherein said spring ends comprise end rings.
