Abstract
Stacks of blanks (10) comprising a largish number of pre-fabricated blanks made of (thin) cardboard are usually made available on pallets (12). The stacks of blanks (10), provided if necessary with a band label (11), are aligned on the pallet (12) in rows (13) and disposed in a plurality of layers (16) the one above the other. A pick-up head (18) serves to unload the stacks and is movable on a support structure (19), configured like a portal, in a vertical and in a horizontal direction. The pick-up head (18) grasps respectively one group of stacks of blanks (10) and sets same down on an onward conveyor (14).
Claims23
A device for picking up and transporting onwards stacks (10) of blanks arranged one above the other, a plurality of stacks being positioned in rows beside one another on a base (12), with layers (16) of stacks being disposed above one another, and the stacks of blanks (10) being able to be grasped either individually or in groups by a pick-up head (18) and set down on an onward conveyor (14) leading to a packaging machine, said device comprising:
- a telescoping member for moving the pick-up head (18) in a horizontal plane, said pick-up head (18) also being movable, along a crossrail (24) extending horizontally, backwards and forwards transversely to a conveying direction of the onward conveyor (14), and also being movable up and down;
- and
- in a working region of the pick-up head (18), an interim store (34) for receiving a supply of the stacks (10), and being arranged in such a way that the stacks (10) may be set down by the pick-up head (18) alternatively on the onward conveyor (14) and in the interim store (34);
- wherein the interim store (34) has a conveying member to receive the stacks of blanks (10).
A device for picking up and transporting onwards stacks (10) of blanks arranged one above the other, a plurality of stacks being positioned in rows beside one another on a base (12), with layers (16) of stacks being disposed above one another, and the stacks of blanks (10) being able to be grasped either individually or in groups by a pick-up head (18) and set down on an onward conveyor (14) leading to a packaging machine, said device comprising:
- a telescoping member for moving the pick-up head (18) in a horizontal plane, said pick-up head (18) also being movable, alone a crossrail (24) extending horizontally, backwards and forwards transversely to a conveying direction of the onward conveyor (14), and also being movable up and down;
- in a working region of the pick-up head (18), an interim store (34) for receiving a supply of the stacks (10), and being arranged in such a way that the stacks (10) may be set down by the pick-up head (18) alternately on the onward conveyor (14) and in the interim store (34);
- and
- in a region of an end of the onward conveyor (14) associated with the pick-up head (18), a lifting member to receive a group of stacks of blanks (10) and to convey same to the interim store (34) or to the onward conveyor (14).
A device for receiving and transporting stacks (10) of blanks arranged on top of one another, a plurality of stacks (10) of blanks being positioned next to each other in rows (13) of stacks on a supporting surface (12), said device comprising:
- a) a pick-up head (18) for gripping at least one of the stacks (10) of blanks, and for setting the stacks (10) down on a discharge conveyor (14) leading to a packaging machine;
- b) a support structure (19) on which the pick-up head (18) is movably mounted, and which includes a plurality of upright posts (20, 21, 22) and an upper, horizontal crossrail (24) coupled to the posts;
- c) a downward directed, vertical telescopic member (25), coupled to said upper crossrail (24), which is displaceable in the horizontal direction thereof along the crossrail (24), and which has at a lower end thereof a carrying device (28) which is movable up and down by said vertical telescopic member;
- and
- d) a horizontal telescopic member (29) which is carried by the carrying device (28), and at an end of which said pick-up head (18) is disposed,
- e) wherein the horizontal telescopic member (29) extends horizontally in, a transverse direction to the crossrail (24), in such a manner that the pick-up head is movable back and forth in said transverse direction by said horizontal telescopic member (29).
A device for receiving and transporting stacks (10) of blanks arranged on top of one another, a plurality of stacks (10) of blanks being positioned next to each other in rows (13) of stacks on a supporting surface (12), said device comprising:
- a) a pick-up head (18) for gripping at least one of the stacks (10) of blanks, and for setting the stacks (10) down on a discharge conveyor (14) leading to a packaging machine;
- b) an intermediate store (34), located in a working area of the pick-up head (18), for receiving a supply of the stacks (10) of blanks, so that the pick-up head (18) can set down the stacks (10) alternatively on the discharge conveyor (14) and in the intermediate store (34);
- and
- c) located at an end of the discharge conveyor (14), a lifting member (38) for receiving a groups of the stacks (10) and for alternatively conveying the groups to the intermediate store (34) and therefrom to the discharge conveyor (14).
