Definitions

  • the invention relates to a device for processing flat products according to the preamble of claim 1 and a method for operating such a device according to claim 14.
  • the invention can be used in particular for processing printed products, e.g. for opening folded printed products or for labeling, labeling, application of adhesive, sticking of by-products, grasping, suction of individual products or for welding a continuous web.
  • CH 632 719 discloses a device for opening multi-sheet paper products, in which opening elements are articulated via radially outwardly directed, pivotable lever on radially directed extensions of a wheel. The extensions and thus the levers with the processing elements engage gear-like in compartments of a cellular wheel in which the products are located. They rest on the outer part of the product and press it against the compartment wall.
  • the levers are pivotable relative to the wheel within a small angular range about a pivot axis extending parallel to the axis of rotation of the wheel. In this device, however, only a retraction of the processing elements in the front region of the compartments is possible, so that only the remote from the axis of rotation of the feeder, outwardly facing product edge is accessible for processing with this device. Shorter formats can not be edited at all.
  • the processing device according to EP-A 0 540 865 is constructed, which serves for adhering inserts to printed products.
  • the processing device according to EP-A 1 275 607 likewise serves for sticking inserts to printed products and is constructed similarly to the devices described above.
  • the processing elements themselves are pivotally mounted on the pivotable lever. Their pivot position is controlled so that the processing elements are always oriented vertically in the processing area, despite a curved orbit with respect to the products to be bonded, ie parallel to the product orientation between two products immerse. In the rear region of the orbit, the processing elements are pivoted at a constant radial orientation of the lever in a tangentially oriented to the orbit position to deduct the supplements of a supply roll can.
  • Other devices that are similar in principle are known from EP-A 0 570 339, EP-A 1 112 861 and EP-A 0 606 550.
  • a processing device for welding a material web with two cooperating subassemblies constructed similarly to the devices described above is known from WO-A 00/35757.
  • the sub-devices each comprise a processing element, which is attached via a short pivotable lever on a rotatable about a rotation axis spoke.
  • the lever is controlled so that its orientation in the room always remains the same, namely perpendicular to the material web to be processed. This allows a vertical action in the processing area.
  • the total length of the lever including the machining element is significantly smaller than the length of the spoke.
  • the achievable working position of the processing element relative to the product to be processed i. the maximum possible distance of the processing element from the front edge of the product facing the device, depending on which part of the orbit of the processing elements for the products without mechanical hindrance is accessible and which hub relative to the products exporting the processing elements in this freely accessible part of the movement path.
  • the stroke or the possible processing position is predetermined by the length of the lever. This is in proportion to the radius of the lever.
  • the invention is therefore based on the object of specifying a device for processing flat products, which despite a small footprint allows a relatively large stroke and thus a given processing depth.
  • the inventive device comprises at least one lever which carries a processing element and by a drive member along a in a

  • the lever is controlled by a perpendicular to the movement plane first
  • a lever is a mechanical connection between the processing element and the drive member, by a certain, usually (but not necessarily) constant distance of the processing element to

  • the lever arm leading to the processing element is arranged outside the entire area in the first subarea and completely within the second subarea or only partially within the area enclosed by the movement path in the case of very long levers.
  • the at least one lever is inclined at least in the second subregion of the movement path relative to the plane of movement.
  • the levers are thus fixed so that their lever arm or at least a part thereof assumes a non-zero angle to the plane of movement.
  • the levers may be straight but also cranked, kinked or bent. In a further remote from the first pivot axis range, the lever can also run parallel to the plane of movement again.
  • the invention allows the use of levers that are long compared to the smallest radius of curvature of the web or - with multiple levers - to the mutual distance.
  • the inclination relative to the plane of movement precludes a mechanical obstruction of the levers or processing elements from one another. With only one lever is advantageously prevented that this grinds on the drive member.
  • the levers around the first pivot axis are free, i. 360 °, rotatable to perform the described change of orientation with respect to the trajectory during one revolution along the trajectory.
  • the inclination allows a synchronous rotation about the first pivot axis without mutual mechanical interference.
  • the levers and thus the processing elements are oriented outwards with respect to the movement path.
  • This subarea or sections thereof can be used as a processing area for processing products which are conveyed past the device, preferably at approximately the same conveying speed and conveying direction such as the (instantaneous) direction of movement and speed of the processing elements.
  • the second subregion of the movement path serves for space-saving return of the processing elements into the processing area.
  • Movement plane corresponds to the second part of the path of movement substantially only that area which is enclosed by the trajectory.

  • this at least one lever at a constant distance from the axis of rotation is pivotable, preferably rotatable by 360 °, connected, in particular in the remote from the axis of rotation outer edge region of the body.
  • the trajectory of the first pivot axes is therefore a circle. If the orientation of the levers in the room does not change, the processing elements also describe a circular path with the same radius. If the lever length corresponds to this radius or larger, the machining elements are freely accessible at least over half of the trajectory and thereby carry out a stroke that corresponds to the radius and at full release maximum the diameter of the trajectory.
  • the invention can be used with advantage also in other types of drives, in particular in connection with a rail-guided conveyor system.
  • the processing elements are in this case for example coupled via the levers with transport means, which are movable individually or in combination by coupling with a suitable drive member along guide rails or otherwise along a defined path of movement.

  • the device can also be used for merely conveying a flat product with a gripper or teat without additional processing.

Abstract

L'invention concerne un dispositif pour exécuter des opérations sur des produits plats (30), en particulier des produits d'imprimerie, ainsi qu'un procédé correspondant pour faire fonctionner ce dispositif. Le dispositif selon l'invention comprend au moins un levier (10) qui porte un élément de traitement (20) et qui peut être déplacé par un organe d'entraînement (1) sur une trajectoire (B) fermée située dans un plan de déplacement (E). Le levier (10) peut pivoter de façon commandée autour d'un premier axe de pivotement (S1) perpendiculaire au plan de déplacement (E) de façon à être orienté dans une première section (B1) de la trajectoire vers l'extérieur par rapport à celle-ci et dans une deuxième section (B2) de la trajectoire (B) vers l'intérieur par rapport à celle-ci pour empêcher que le levier (10) soit en porte-à-faux et permettre ainsi d'obtenir un dispositif compact. Du fait que le levier (10) est incliné par rapport au plan de déplacement (E) au moins dans la deuxième section (B2) de la trajectoire (B), des leviers (10) relativement longs peuvent être utilisés malgré la forme compacte, sans que ces leviers se gênent d'un point de vue mécanique lors du déplacement sur la trajectoire. Le dispositif selon l'invention sert en particulier à ouvrir des produits d'imprimerie pliés, mais une utilisation à d'autres fins est également possible.
