Description

State of the art

[0001] The invention relates to a product handling device, in particular a carton magazine loading device, for handling stacks of packaging blanks, in particular cardboard blanks, preferably for automatically loading a carton magazine of a packaging machine with stacks of packaging blanks, with at least one handling unit comprising loading and / or contact elements having a support surface on which the stack of packaging blanks can be placed with a main extension area at least during handling.

[0002] Such product handling devices are known, for example, under the product name Cermex FlexiLoad™ from Sidel International SA. In these known product handling devices, the stacks of packaging blanks are held by means of the lifting and / or positioning elements by a frictional connection acting parallel to a main extensional surface of the stacks of packaging blanks and / or a positive-locking connection acting perpendicular to the main extensional surface of the stacks of packaging blanks, in particular by clamping the stacks of packaging blanks between at least two lifting and / or positioning elements. This can lead to inaccurate alignment of the packaging blanks in the carton magazine, since the stacks of packaging blanks can slip between the two lifting and / or positioning elements if the frictional force along the main extensional surface of the stacks of packaging blanks is insufficient.Furthermore, the stacks of packaging blanks, particularly when the packaging blanks have a smooth surface, can slip between the loading and / or loading elements during handling with the known product handling device. This can occur due to unintentional contact, preferably caused by an external force impulse applied to the stack of packaging blanks. This can also contribute to inaccurate positioning of the packaging blanks. Moreover, precise alignment of the packaging blanks is necessary before handling them with the known product handling device to ensure accurate loading of the carton magazine.

[0003] The object of the invention is, in particular, to provide a generic product handling device, a generic method, and / or a generic packaging machine with improved properties with regard to the simple and safe handling of packaging blanks and / or the precise loading of a carton magazine. This object is achieved according to the invention by the features of claims 1, 7, and 11, respectively, while advantageous embodiments and further developments of the invention can be found in the dependent claims.

Preferably, the, and in particular three, loading and / or positioning elements are movably mounted on the base body of the handling unit, in particular relative to each other, relative to the industrial robot, and / or relative to the packaging machine.Preferably, individual axes of movement of the, in particular three, mounting and / or contact elements extend at least substantially parallel to a principal plane of extension of the handling unit. A "principal plane of extension" of an element or component is understood to be, in particular, a plane that extends parallel to a largest side face of the smallest imaginary cuboid that just completely encloses the element or component, and in particular passes through the center of the cuboid. At least two axes of movement of the, in particular three, mounting and / or contact elements preferably run coaxially, in particular the axes of movement of the mounting and / or contact elements designed as side-flange slot engagement elements.At least one of the axes of movement of the, in particular three, loading and / or positioning elements runs transversely, in particular at least substantially perpendicularly, to at least one of the axes of movement of the, in particular three, loading and / or positioning elements, in particular to the two coaxial axes of movement of the, in particular three, loading and / or positioning elements.

The, in particular three, loading and / or positioning elements can be mounted to move continuously or in steps on the base body. It is also conceivable that the, in particular three, loading and / or positioning elements are mounted to move spring-loaded elements on the base body, in particular to counteract damage to the stack of packaging blanks during handling by the handling unit.At least two of the mounting and / or installation elements are preferably arranged in alignment with each other, particularly when viewed along a direction that runs at least substantially parallel to the main extension plane of the handling unit.

[0009] The main extension surface of the stack of packaging blanks, when arranged on the handling unit, preferably extends at least substantially parallel to the main extension plane of the handling unit. The, in particular three, mounting and / or contact elements preferably each comprise a support surface against which the stack of packaging blanks, in particular the bottommost packaging blank of the stack, can be placed with its main extension surface, at least during handling. Preferably, at least two, in particular all, of the mounting and / or contact elements each comprise a side contact surface extending transversely, in particular at least substantially perpendicularly, to the support surface, against which the stack of packaging blanks can be placed with a side surface extending transversely to the main extension surface, at least during handling.The term "essentially perpendicular" is intended to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, especially when viewed in a projection plane, enclose an angle of 90° and the angle has a maximum deviation of, in particular, less than 8°, advantageously less than 5°, and most advantageously less than 2°. Preferably, all side contact surfaces of the mounting and / or attachment elements are arranged on the side of the mounting and / or attachment elements facing the stack of packaging blanks when the stack is arranged on the handling unit.Preferably, a positive-locking connection between the mounting and / or mounting elements and the stack of packaging blanks can be realized by means of the side contact surfaces of the mounting and / or mounting elements, acting along an area at least substantially parallel to the main extension surface of the stack of packaging blanks.

[0010] Furthermore, it is proposed that, particularly when considering a plane extending at least substantially perpendicular to a principal extension plane of the handling unit, especially the aforementioned principal extension plane, at least one, and in particular at least two, of the mounting and / or contact elements are L-shaped, wherein one leg of the L-shaped configuration forms the bearing surface and another leg of the L-shaped configuration forms the side contact surface. Preferably, a principal extension axis of the leg extends at least substantially parallel to the principal extension plane of the handling unit. A principal extension axis of the other leg preferably extends at least substantially perpendicular to the principal extension plane of the handling unit. Preferably, all three mounting and / or contact elements are L-shaped.The L-shaped configuration of at least one of the mounting and / or support elements can be formed by either having the leg and the other leg of the mounting and / or support element formed as a single piece, or by having the leg and the other leg of the mounting and / or support element formed separately and arranged in an L-shaped configuration relative to each other, wherein the leg and the other leg are either directly connected to each other or spaced apart relative to each other. Further configurations of the mounting and / or support element that would appear useful to a person skilled in the art for realizing an L-shaped configuration or for realizing a support surface and a side contact surface oriented transversely to it, in particular at least substantially perpendicularly, are also conceivable.The term "one-piece" is to be understood in particular as being joined at least by a material bond, for example by a welding process, an adhesive bonding process, an injection molding process, and / or another process that would appear appropriate to a person skilled in the art, and / or advantageously as being formed in one piece, such as by being manufactured from a single casting and / or by being manufactured using a single- or multi-component injection molding process, and advantageously from a single blank. The inventive design of the product handling device advantageously enables a positive locking of the packaging blanks by means of the mounting and / or contact element, in particular by means of the mounting and / or contact elements. It enables advantageously reliable and secure alignment of the packaging blanks during handling of the packaging blanks with the mounting and / or contact elements.It is advantageous and structurally simple to achieve self-alignment on the support and / or mounting elements, particularly as a result of the interaction of the contact surfaces and the side contact surface(s) with the stack of packaging blanks. A three-point support for stacks of packaging blanks can be implemented particularly advantageously, especially to ensure the secure holding of stacks of, in particular, unstable packaging blanks.

[0011] Furthermore, it is proposed that the mounting and / or contact elements, in particular each, be movably mounted relative to one another, in particular translationally, along an axis of movement, in particular one of those already mentioned, which runs at least substantially parallel to the contact surface. The contact surface(s) preferably extend at least substantially parallel to the main plane of extension of the handling unit, especially in the case of a translationally movable mounting of the mounting and / or contact elements on the base body of the handling unit. Preferably, the mounting and / or contact elements are slidably mounted on the base body of the handling unit.In an alternative embodiment of the handling unit, it is conceivable that the lifting and / or placing elements are pivotably mounted on the base body of the handling unit about their respective axes of movement, wherein the respective contact surface of the lifting and / or placing elements is aligned at least substantially parallel to the main plane of extension of the handling unit in at least one movement state of the lifting and / or placing elements. For moving the lifting and / or placing elements, the handling unit preferably includes at least one drive, such as an electric motor, a hydraulic cylinder, a pneumatic cylinder, or the like.

The inventive design of the product handling device advantageously allows for a positive-locking hold of the packaging blanks by means of the mounting and / or positioning element, in particular by means of the mounting and / or positioning elements.The movable mounting of the support and / or attachment elements according to the invention allows for an advantageously positive-locking connection between the support and / or attachment elements and the stack of packaging blanks, acting at least substantially parallel to the main extensional surface of the stack.

However, it is also conceivable that the insertion aid element has another design that would appear useful to a person skilled in the art, and which is suitable for moving apart the stack of packaging blanks and further packaging blanks, in particular those arranged on or attached to the transport or storage device, preferably the pallet.The insertion aid element is preferably formed integrally with one of the mounting and / or contact elements, in particular with the mounting and / or contact element designed as a gripping finger. However, it is also conceivable that the insertion aid element is designed separately from the mounting and / or contact elements and as an independent element, in particular a movable one, especially as a separate compressed air lance or the like. Furthermore, it is conceivable that each of the mounting and / or contact elements is assigned an insertion aid element, or that each of the mounting and / or contact elements is formed integrally with an insertion aid element designed as a compressed air nozzle.Preferably, the insertion aid element is designed to fan out the stack of packaging blanks and the additional packaging blanks, particularly those arranged on or attached to the transport or storage device, preferably the pallet, in order to facilitate easy separation of the stack of packaging blanks handled by the handling unit from the additional packaging blanks, particularly those arranged on or attached to the transport or storage device, preferably the pallet. Preferably, the insertion aid element is designed to move the stack of packaging blanks and the additional packaging blanks, particularly those arranged on or attached to the transport or storage device, preferably the pallet, apart in order to support at least one of the loading and / or contact elements, in particular the loading and / or contact element designed as a gripping finger.Preferably, compressed air can be introduced between the stack of packaging blanks and the other packaging blanks, particularly those arranged on or attached to the transport or storage device, preferably the pallet, by means of the insertion aid element before at least one of the mounting and / or contact elements, in particular the mounting and / or contact element designed as a gripping finger, is moved into place. This is done to cause the stack of packaging blanks and the other packaging blanks to separate. The inventive design of the product handling device advantageously allows for the simple insertion of at least one of the mounting and / or contact elements to secure the packaging blanks in a form-fitting manner.It can advantageously enable simple and safe handling of packaging blanks.

[0013] It is further proposed that the handling unit comprises at least one separating element, movably mounted along an axis of movement extending at least substantially parallel to the support surface relative to the mounting and / or attachment elements, in particular translationally, which is designed to at least partially separate a stack of packaging blanks to be handled from further packaging blanks, in particular to at least partially lift them, especially after the stack of packaging blanks has been moved apart from the further packaging blanks, in particular those arranged on or attached to the transport or storage device, preferably the pallet, by means of the insertion aid element. The separating element is preferably insertable on at least one side of the stack of packaging blanks to be handled, between the stack of packaging blanks to be handled and the further packaging blanks.It is conceivable that the separating element can be inserted only partially between the stack of packaging blanks to be handled and the other packaging blanks, in particular such that the stack of packaging blanks to be handled and the other packaging blanks still abut each other at least on one side, or that the separating element can be inserted completely between the stack of packaging blanks to be handled and the other packaging blanks, in particular such that the stack of packaging blanks to be handled is completely lifted from the other packaging blanks. The separating element is preferably movably mounted on the base body of the handling unit. Preferably, the separating element is designed as a wedge-shaped insertion element.

Preferably, the handling unit comprises at least two separating elements, which are movably mounted, in particular translationally.Preferably, the handling unit comprises at least one pressure element which is designed, particularly temporarily, to exert a pressure force on the stack of packaging blanks along a line acting at least substantially perpendicular to the main plane of extension of the handling unit. The pressure element is preferably movably mounted on the base body of the handling unit, particularly in a translationally movable manner. Preferably, the pressure element can be driven by an additional drive of the handling unit, in particular an electric motor, a hydraulic cylinder, a pneumatic cylinder, or the like. The pressure element is preferably arranged on a side of the base body of the handling unit that faces away from the gripping and / or contact element designed as a gripping finger.The inventive design of the product handling device advantageously enables reliable separation of the stack of packaging blanks and the further packaging blanks, in particular those arranged on or at the transport or storage device, preferably the pallet, in order to enable simple and safe handling of packaging blanks by means of the lifting and / or attachment elements.

[0014] Furthermore, it is proposed that the handling unit be designed to hold a stack of packaging blanks to be handled by means of a positive-locking connection that acts at least substantially parallel to a main extension plane of the handling unit. The positive-locking connection preferably acts along two directions extending transversely, and in particular at least substantially perpendicularly, to each other, with one of the directions extending at least substantially perpendicular to the main extension plane of the handling unit and the other of the directions extending at least substantially parallel to the main extension plane of the handling unit. It is conceivable that, in an alternative embodiment, the product handling device for solving the aforementioned problem could be designed independently of the side contact surface extending transversely, and in particular at least substantially perpendicularly, to the support surface.Preferably, in the alternative embodiment, particularly in the embodiment designed independently of the side contact surface extending transversely, and in particular at least substantially perpendicularly, to the support surface, the product handling device comprises at least one handling unit, which includes, in particular, three, mounting and / or contact elements, each of which has, in particular, a support surface against which the stack of packaging blanks can be placed with a main extension surface at least during handling, wherein the handling unit is provided to hold a stack of packaging blanks to be handled by means of a positive locking connection that acts at least substantially parallel to a main extension plane of the handling unit.The inventive design of the product handling device advantageously enables a positive-locking hold of the packaging blanks by means of the mounting and / or contact elements, in particular by means of the mounting and / or contact elements. It advantageously enables simple and safe handling of the packaging blanks. Particularly due to the advantageously reliable and secure alignment of the packaging blanks during handling with the mounting and / or contact elements, it advantageously enables precise placement of the packaging blanks in the carton magazine. It advantageously and structurally simple enables self-alignment on the mounting and / or contact elements, particularly due to the interaction of the support surfaces and the side contact surface(s) with the stack of packaging blanks.A three-point support for stacks of packaging blanks can be particularly advantageous, especially to ensure the secure holding of stacks of, in particular, unstable packaging blanks.
