Abstract: An apparatus for feeding separator sheets (20) to a stack is disclosed. Separator sheets (20) made of paper or another material are disposed between carton layers (19) of a pallet (13) loaded with cartons (10). The separator sheets are produced by a separate separator sheet unit (25) by way of being severed from a web of material (21 ) and are placed onto the carton layers (19). The separator sheet unit (25) operates independently of a palletizer (12) for the cartons (10). The separator sheet unit (25) is comprised of a web conveyor (29) for transporting the web of material (21) in portions, and a blank conveyor (30) for receiving and transporting the separator sheets ( 20) and placing them on the carton layers (19). Additionally, a cutting unit (37) for severing a blank (23) is provided.

Abstract: In the packaging art, palletizers (23) serve for transporting, i.e. lifting, conveying and depositing cartons (10) and the like. A gripper (27) is located on an articulated arm (24) and is provided with upright carrying arms (29, 30) and carrying legs (31, 32) arranged thereon for grasping the cartons (10) at their bottom side. The carrying legs can be pivoted from a horizontally directed carrying position to an essentially vertical release position which allows a trouble-free lifting of the gripper after a carton has been deposited, even if there is little space. The carrying arms 29, 30 of the gripper 27 are themselves pivotable from an essentially upright position to an inclined position in which they are spread apart in order to be able to grasp cartons when the carrying legs (31, 32) are horizontally directed.

Abstract: The handling of cup-shaped containers (cups 10) for holding foods is difficult, as the cups (10) are delivered nested into one another in the form of a cup stack (14) in cartons. Hitherto, the cup stacks (14) formed by the cups (10) have been handled manually. A lifting and pivoting conveyor (25) with a gripper is used for an exclusively mechanical handling of the cups or cup stacks (14). The gripper (27) has holding mechanisms (31), each for engaging one cup stack (14). The holding mechanisms (31) of the gripper (27) are designed as suction chambers (32) with a lower suction opening (44) for engaging a cup stack (14) by negative pressure. In the region of the suction opening (44), sealing devices are attached to the suction chamber (32), especially an inner brush strip (48) and an outer rubber lip (50), which contact the critical contour of the cup stack (14) in a sealing manner.

Abstract: The invention concerns a device for conveying layers comprising a multitude of individual objects, in particular glasses, cans, etc., preferably for loading and unloading pallets, a suction head being provided for picking up a layer of individual objects, which suction head has a plurality of suction holes. On the one hand, said suction holes face the top side of the objects and, on the other hand, are connected to a source of negative pressure. To avoid a breakdown of the negative pressure as a result of suction holes not being allocated over individual objects, a long flow duct is connected to each suction hole on the side facing away from the individual objects, which flow duct is coupled with the source of negative pressure or the suction chamber.

Abstract: The lifting and transportation of sensitive articles incapable of bearing a mechanical load, without manual involvement, presents special difficulties in packaging technology. This applies, above all, to tray packs in which articles are arranged standing on a bottom part (11) of small height, without any additional anchoring. For grasping and lifting articles of this type, there is provided a raisable and lowerable suction box (15) which, with suitable dimensions, is placed over the article in the manner of a bell. By the generation of a vacuum within the suction box (15), the article (tray pack 10) is held carefully and can be lifted by means of the suction box (15). Side walls (22) of the suction box (15) are arranged pivotably, to make it easier to place the suction box (15) onto the article.

Abstract: Lifter for loads, in particular a palletizer for stackable objects, comprising a load carrier which can be moved up and down, in particular an articulated swivel arm (16) on whose free end an element is arranged for seizing the objects, the up and down or lifting and lowering movements of the load carrier being effected along a vertical guide, in particular along upright columns (19), and a drive (13)for the lifting and lowering movement of the load carrier at the upper or lower end of the vertical guide (columns 19), the connection between the drive (13) and the load carrier (swivel arm 16) being made by a toothed belt (14) which on one side is passed around a pinion (15) allocated to the drive (13) and on the other side is passed around a toothed disc (17) rotatably mounted on the end of the vertical guide (columns 19) opposite the drive side and whose free ends are each attached to the load carrier or a guide block (26) of the same.
