Abstract
This disclosure relates to a denesting element for a denesting apparatus for denesting a stack of objects in a predetermined denesting direction, comprising a base and a contact section, wherein the base is disposed between the contact section and a drive element of the denesting apparatus, wherein the drive element drives the base rotationally or translationally, and wherein the contact section, when the denesting element is mounted in the denesting apparatus, is capable of being biased towards and away from a stack of trays by being elastically displaceable between an extended position and a retracted position.
Claims9
A denesting element for a denesting apparatus for denesting a stack of objects in a predetermined denesting direction, comprising:
- a base and a contact section, wherein the base is disposed between the contact section and a drive element of the denesting apparatus, wherein the base is operable for mounting on the drive element of the denesting apparatus, and wherein the contact section is operable for entering a gap formed by edges of objects of the stack of objects,
- wherein the drive element drives the base rotationally,
- wherein, when the denesting element is mounted in the denesting apparatus, and when the base of the denesting element is mounted on the drive element, during denesting of objects in the denesting apparatus, when the drive element performs at least a partial rotational movement around an axis along the predetermined denesting direction, the contact section is inserted into a gap between an edge of a first object and an edge of a second object in the stack of objects to be denested from the denesting apparatus and the contact section contacts the edge of the first object,
- wherein the first object is an outermost object in relation to the predetermined denesting direction, wherein the second object is an object situated between the first object and a remaining stack of objects,
- wherein the contact section, during denesting of objects in the denesting apparatus, is capable of being biased towards and away from a stack of objects by being elastically displaceable in relation to the base between an extended position and a retracted position, and
- wherein the extended position of the contact section is a position more towards the stack of objects than the retracted position of the contact section, and the retracted position of the contact section is a position less towards the stack of objects than the extended position of the contact section.
A denesting apparatus with a denesting element for denesting a stack of objects in a predetermined denesting direction, comprising:
- a drive element for operating the denesting element during denesting of objects, wherein the drive element, during denesting of objects in the denesting apparatus, performs at least a partial rotational movement around an axis along the predetermined denesting direction;
- and
- a contact section of the denesting element, wherein the contact section, during the at least partial rotational movement of the denesting element, performs a translational movement, in relation to a base of the denesting element, between an extended position and a retracted position,
- wherein the contact section during a preliminary period of the translational movement, in relation to the base of the denesting element, is in an extended position and extends into a gap between an edge of a first object and an edge of a second object, and
- wherein the contact section, during a later period of the translational movement, in relation to the base of the denesting element, contacts an edge of the first object and, during the later period of the translational movement, displaces elastically from an extended position to a retracted position because of the contact section contacting the edge of the first object.
A method for denesting objects with a denesting apparatus including a denesting element, comprising:
- contacting, by a contact section, an edge of a first object, wherein the contact section is inserted into a gap between an edge of a first object and an edge of a second object in a stack of objects to be denested from the denesting apparatus, and wherein the first object is an outermost object in relation to a predetermined denesting direction, and where the second object is an object situated between the first object and a remaining stack of objects;
- displacing elastically, in relation to a base, the contact section, and in relation to an extended position, to a retracted position;
- and
- denesting an outermost first object from the stack of objects by the contact section separating the outermost first object from a subsequent second object of the stack of objects.
