Definitions

  • the invention is in the field of further processing of products, in particular printed products, such as newspapers, magazines, brochures and the like. It relates to devices and methods for feeding products and for feeding and folding of sheet-like and flexible products, in particular printed products, according to the preamble of the independent claims.
  • the folding of printed products in particular of individual sheets or already folded products, is known per se.
  • the folding device usually connects directly to a rotary printing press and can process the printed products in the flow while they are being conveyed. From the rotary printing press, the printed products are usually overlapped with each other, i. as a scaly formation. The folding takes place in some folders after a separation of the printed products.
  • Other folding devices e.g. according to US Pat. No. 7,458,926, are able to fold the printed products without singling in the shingled stream.
  • Known folding devices comprise an input conveyor, which receives the printed products to be folded as a scale flow or individually and further in a conveying surface and in a conveying direction. They further include a folding unit, which takes over the printed products to be folded from the input conveyor, further conveying and folding the printed products in the scale flow or individually in a direction parallel to the conveying direction folding direction. With an output unit, the folded printed products are transferred to a processing station. Here, for example, by repositioning the isolated folded products, a new imbricated formation is formed.
  • the invention is therefore based on the object to avoid the disadvantages mentioned and in particular to provide a conveyor assembly for feeding products and a folding device and a corresponding folding method, comprising a conveyor assembly for feeding products, which provide a product-accurate processing and thus an extension the possible uses of a folding device allows.

  • the uniformity device acts on the incoming product flow so that not only the conveying speed of the products is known, but also their mutual distance. From this, in principle, the position of each product can be determined at any time when passing through the folding device. This information or the clock can be used for further processing processes within the folding device. As a result, the functionalities of the folding device over known devices are extended and the range of applications is increased. These further processing processes are preferably subject to the same cycle.
  • the corresponding drives are preferably coupled together, for example with a common control device. Different functional elements from one or more of the machining processes can have a common drive and coupled by mechanical couplings for transmitting movement with each other and with the common drive.
  • Another advantage of the uniformity is that irregularities in the zuformte formation before entering the folding unit are compensated. It can therefore not come to damming or jamming of products in the folder due to local accumulation in the incoming formation.
  • Producing a defined cycle means that a defined distance of the leading or trailing edges of successive printed products is produced. Together with the known, but not necessarily constant, conveying speed within the folding device can therefore be determined the time at which any product is conveyed past a predetermined location. Here then a product-specific processing can take place.
  • the defined cycle can be realized, for example, in that the comparative moderating device has at least one alignment element for aligning the leading or trailing edges of the products transported on the conveying surface.

Abstract

L'invention concerne un dispositif pour plier des produits d'impression (10) comprenant un transporteur d'entrée (100) et une unité de pliage qui est traversée par des produits d'impression (10) dans un sens de transport (F1) coïncidant avec le sens du pliage à produire. Le transporteur d'entrée (100) présente un dispositif de régulation (120) qui est en mesure de réguler les produits d'impression (10) de telle manière que les produits d'impression (10) soient acheminés vers l'unité de pliage à une cadence déterminée. La régulation permet le pliage d'un flux chevauchant sans séparation préalable. En outre, la cadence peut être utilisée dans d'autres postes qui sont intégrés dans l'unité de pliage. De ce fait, les fonctionnalités du dispositif de pliage et le domaine d'utilisation sont élargis par rapport aux dispositifs connus.
