Abstract:
A method for applying at least one strip section (14a) to a flat product composition (11a, b) wherein a strip section (14a) or an individual element of a specified length is provided and subsequently applied around a selected edge (31) of the product composition (14a, b) in a perpendicular manner with respect to said edge (31) so as to rest against the product composition (14a, b). A reliable operation that is independent of the type of the strip is achieved in that the selected edge (31) of the product composition (11a, b) is moved forward along a transporting path (12), the strip section (14a) is held ready at a specified point of the transporting path (12) so as to intersect the transporting path (12), the selected edge (31) of the product composition (11a, b) is moved past the specified point, and at the same time the selected edge (31) drives the strip section (14a) that is held ready.
Abstract:
The invention relates to an apparatus (10) for the intermediate storage of planar articles, in particular print products, which can be spooled in an imbricated stream arrangement, which intermediate storage apparatus (10) has a plurality of substantially mutually adjacent winding stations (D1, . . . , D4), to which the articles to be temporarily stored are fed for spooling on connecting lines (14) or from which the temporarily stored articles, after being unspooled, are led off on the connecting lines (14), as well as at least one supply line (11) and at least one discharge line (12), which cross the connecting lines (14) at predefined junctions. The transfer apparatuses (13) are arranged displaceably on the connecting lines (14), which transfer apparatuses at the junctions selectively connect the connecting lines (14) to the at least one supply line (11), or the at least one discharge line (12), for transfer of the planar articles between the lines (11; 12; 14).
Abstract:
A conveying device for conveying and aligning flat products or stacks of flat products, in particular printed products, includes leading pins for stop on a leading edge of conveyed products and trailing pins or pushers for stop on a trailing edge of the conveyed products. The products are insertable between the leading and trailing pins and are thus aligned by the pins. A distance between successive pushers is adjustable without parts of the device having to be exchanged.
Abstract:
The invention relates to a method and to a device for creating a product flow according to a predefined sequence (S). The products (A, B, C) are fed from different feed flows of a grouping path (G) and there, according to the sequence (S), are deposited onto a conveyor (10, 10) with a closed revolving path (U). According to the invention a repair function is realised in which the products (A, B, C) are then only transferred from the conveyor to a further-processing station if the sequence (S) is correct and all products (A, B, C) are present with the desired quality. Otherwise, the products (A, B, C) are led by the continuously operated conveyors (A, B, C) back to the grouping path (G). Here, the error is corrected by way of the deposition of the missing product (A, B, C), whilst the deposition of new products (A, B, C) is interrupted. For error correction, one may previously provide a discharge of a defect or wrong product (A, B, C). After the error correction, the creation of the product flow is continued by way of the sequentially correct deposition of further products (A, B, C). The method permits the error-free and sequentially correct creation of infinitely long and infinitely assembled sequences (S).
Abstract:
In order to package flat objects (1) with the aid of a quasi-endless packaging material web, the packaging material web is placed around a row (4) of the objects (1), in which these objects are conveyed one after the other and in an interspaced manner, whereupon longitudinal seams are made in the packaging material web and transversal seams are made between the objects (1) whereby separating the packaged objects from one another. In contrast to prior art packaging methods during which the row is formed before the packaging material web is fed thereto, the invention provides that the row is directly formed on the packaging material web (2) during which the objects are, by acceleration, separated out from a supply stream (3), in which they are fed while overlapping one another, and directly placed upon or pushed onto the packaging material web (2). Forming the row (4) directly on the packaging material web (2) eliminates additional conveying steps whereby shortening the entire required conveyor lines and rendering stabilizing means for stabilizing the objects (1) during conveyance unnecessary thus leading to very compact and simple packaging devices. The packaging method is particularly suited for packaging objects that consist of a number of stacked printed products or other flat articles.
Abstract:
For processing flat objects (10), in particular for packing printed products or small groups thereof, using a continuous packing material, the objects are conveyed in a conveying stream in which they are arranged in succession and essentially parallel to the conveying direction, and possibly between two layers of packing material, along a part of the periphery of a processing drum (1). The processing drum (1) has axially extending support elements (2) and tool elements (3) regularly alternating around its periphery. A radial position of the supporting and tool elements is adjustable, to accommodate varying formats of the objects to be processed. The processing drum also includes a pressing belt (4) extending from an entry point (A) to an exit point (B) on the drum periphery and holding and pressing the objects being conveyed on the drum periphery against the tool elements. To render further adjustments unnecessary when the radial position of the support and tool elements is changed, the pressing belt (4) is arranged to guide the objects on to and/or off the periphery of the processing drum.
Abstract:
The invention relates to a method of conveying flat, flexible products, in particular printed products, in which the products are conveyed continuously by means of a conveying device in an overlapping formation to a transfer region and are picked up there by an outward conveyor. The outward conveyor comprises grippers which are moved along a movement path, can be controlled individually to open and close and have at least two gripper jaws, whose alignment relative to the movement path can be varied. According to the invention, the grippers are moved in such a way that the gripper jaw facing the conveying device engages in the manner of a shovel underneath the trailing edge of at least one product resting partly on the trailing product in the transfer region, without said product having previously been raised off the trailing product, and then raises said product. The products, before or after being engaged underneath, are braked relative to trailing products and/or fixed in their position. The invention also relates to an apparatus for implementing the method.
Abstract:
For converting a stream of flat articles from transverse conveyance to parallel conveyance, two continuously operated conveyors are provided, a transverse conveyor having a direction (FQ) of transverse conveyance and serving as supplying conveyor and a parallel conveyor having a direction (FP) of parallel conveyance and serving as removing conveyor. The direction (FQ) of transverse conveyance and the direction (FP) of parallel conveyance encompass an angle. The articles are pushed one after the other out of an outlet of the supplying conveyor towards an entrance of the removing conveyor. Before a trailing zone of the article has left the supplying conveyor, a leading zone of the article is grasped by an alignment device and is conveyed onwards with the speed of the parallel conveyor in the direction (FP) of parallel conveyance and is thereby aligned to the entrance of the removing conveyor, while the trailing zone is bent between the alignment device and the outlet of the supplying conveyor. The stream conversion can also be operated in the reverse sense and again with continuously operated conveyors and nonetheless the articles are at all times during conversion safely guided.
Abstract:
A method and apparatus for producing stacks of flat objects, such as printed products 28, wherein the printed products are fed to a preliminary stacking compartment 20, into which opens the outlet 32 of an arrangement 12 for feeding additional sheets 14. Located beneath the preliminary stacking compartment is a final compartment 36, which can be rotated through 180° about a vertical axis of rotation 38 in order to be able to receive from the preliminary stacking compartment 20 sub-stacks 34 which have been rotated in relation to one another. Each sub-stack 34 may be formed on an additional sheet 14 in the preliminary stacking means 18, as a result of which, in the complete stack 54, the sub-stacks 34, each forming a layer, are separated from one another by an additional sheet 14.
