Gripper arm for containers and gripper device having such gripper arms

A device comprising:

• a first gripper arm having a gripping section for gripping, holding and guiding containers responsive to a force moving the gripping section from an open position into a gripping position and vice versa;
• a bore included in the first gripper arm to support a bearing pin for pivotably fixing the first gripper arm to the device;
• and
• a first spring tongue integrally formed on the first gripper arm to form part of an energy store for moving the gripping section from the gripping position into the open position and vice versa, wherein the first spring tongue is elastically deflectable and operatively engages with a second spring tongue of a second gripper arm, wherein the first spring tongue has substantially a same width in an axial direction of the bore as the first gripper arm, the second gripper arm in a mirror-inverted configuration with the first gripper arm.

A device comprising:

• a first gripper arm having a gripping section for gripping, holding and guiding containers responsive to a force moving the gripping section from an open position into a gripping position and vice versa, wherein the force is exerted by a control cam;
• a bore included in the first gripper arm to support a bearing pin for pivotably fixing the first gripper arm to the device;
• and
• a first spring tongue integrally formed on the first gripper arm to form part of an energy store for moving the gripping section from the gripping position into the open position and vice versa, wherein the first spring tongue is elastically deflectable and operatively engages with a second spring tongue of a second gripper arm, the second gripper arm in a mirror-inverted configuration with the first gripper arm.

A device comprising

• a first gripper arm having a gripping section for gripping, holding and guiding containers responsive to a force moving the gripping section from an open position into a gripping position and vice versa, wherein the gripping section further includes one of a tapered profile and a step profile from a lower side to an upper side of the first gripper arm;
• a bore included in the first gripper arm to support a bearing pin for pivotably fixing the first gripper arm to the device;
• and
• a first spring tongue integrally formed on the first gripper arm to form part of an energy store for moving the gripping section from the gripping position into the open position and vice versa wherein the first spring tongue is elastically deflectable and operatively engages with a second spring tongue of a second gripper arm, the second gripper arm in a mirror-inverted configuration with the first gripper arm.

A device comprising:

• a first gripper arm having a gripping section for gripping, holding and guiding containers responsive to a force moving the gripping section from an open position into a gripping position and vice versa;
• a bore included in the first gripper arm to support a bearing pin for pivotably fixing the first gripper arm to the device;
• and
• a first spring tongue integrally formed on the first gripper arm to form part of an energy store for moving the gripping section from the gripping position into the open position and vice versa, wherein the first spring tongue is elastically deflectable and operatively engages with a second spring tongue of a second gripper arm, wherein the first gripper arm further includes an integrally formed spring bar that is elastically deflectable to compensate for the force exerted during moving the gripping section of the first gripper arm, wherein the spring bar forms a closed circumferential recess with the first gripper arm, the second gripper arm in a mirror-inverted configuration with the first gripper arm.

An apparatus comprising:

• a first gripper arm having a gripping section for gripping, holding and guiding containers responsive to a force exerted by a control cam moving the gripping section from an open position into a gripping position and vice versa;
• a bore included in the first gripper arm to support a bearing pin for pivotably fixing the first gripper arm to the apparatus;
• a first spring tongue integrally formed on the first gripper arm to form part of an energy store for moving the gripping section from the gripping position into the open position and vice versa, wherein the first spring tongue is elastically deflectable and operatively engages with a second spring tongue of a second gripper arm, the second gripper arm in a mirror-inverted configuration with the first gripper arm;
• and
• a first end piece of the first spring tongue and configured to operatively engage with a second end piece of the second spring tongue, wherein the operative engagement with the second end piece is in a form of a cross-lap joint.

An apparatus comprising:

• a pair of gripper arms in a mirror-inverted configuration, each gripper arm having a gripping section for gripping, holding and guiding containers;
• a bore included in each gripper arm to support a bearing pin for pivotably fixing the respective gripper arm to the apparatus;
• a control cam affixed to the gripper arms for moving the gripping section from an open position into a gripping position and vice-versa;
• and
• a spring tongue integrally formed on each gripper arm to form part of an energy store for moving the gripping section of the respective gripper arm from the gripping position into the open position and vice versa, wherein the spring tongues are elastically deflectable and operatively engage with each other, and wherein the operative engagement is in a form of a cross-lap joint.
