Die vorliegende Erfindung betrifft eine Vorrichtung zum Trennen von flachen Produkten von einem Stapel aus flachen Produkten, wobei die Vorrichtung einen Hebehaken umfasst, der von einer geschlossenen Position in eine offene Position bewegbar ist, und wobei der Hebehaken den Boden eines Stapels aus flachen Produkten in seiner geschlossenen Position hält.The present invention relates to a device for separating flat products from a stack of flat products, the device comprising a lifting hook, which is movable from a closed position to an open position, and wherein the Lift hooks the bottom of a stack of flat products in its closed Holds position.

Bei der Herstellung von Büchern, einschließlich Broschüren, Zeitschriften, Magazinen und ähnlichem ist die Verwendung von Zusammentragsystemen bekannt. Diese Systeme weisen üblicherweise eine Transportvorrichtung auf, auf der einzelne flache Produkte wie Signaturen oder Bogen in einem Buchblock gesammelt werden, die dann bearbeitet und gebunden werden. Üblicherweise ist eine Reihe von Zuführvorrichtungen entlang der Transportvorrichtung angeordnet, wobei jedes der Magazine eine Zuführvorrichtung zum Zuführen eines einzelnen flachen Produkts aus einem Stapel von Signaturen auf die Transportvorrichtung umfasst, um nach und nach den Buchblock zu schaffen oder einen zusätzlichen Bogen in eine Tasche einer Taschenzuführvorrichtung oder in eine Zeitung, die in der Tasche angeordnet ist, einzulegen. Solche Zuführvorrichtungen verwenden üblicherweise eine Bogentrennvorrichtung zum Trennen eines Bogen oder anderen einzelnen flachen Produkts aus einem Stapel von flachen Produkten, der in jedem Magazin angeordnet ist. Die einzelnen flachen Produkte werden an dessen unterem Ende aus dem Stapel entfernt.In the production of books, including brochures, magazines, and magazines Similar use of collation systems is known. These systems usually have a transport device on which individual flat products such as Signatures or sheets are collected in a book block, which are then edited and be bound. Typically, a series of feeders are along the Transport device arranged, each of the magazines a feed device for Feed a single flat product from a stack of signatures onto the Transport device includes to gradually create the book block or one additional sheets in a pocket of a pocket feeder or in a newspaper, which is arranged in the pocket.

Eine Bogentrennvorrichtung dieser Art ist z.B. aus der US 3,988,016 bekannt. Diese Schrift beschreibt eine Hochgeschwindigkeitspapiereinlegevorrichtung zum Einlegen von Beilagen in Zeitungen. Die Beilagen sind so angeordnet, dass sie einen Stapel bilden und ein Vakuumgreifelement ergreift die unterste einzulegende Beilage von dem Stapel und trägt sie zu einem Walzenpaar, das die Einlage an eine geöffnete Zeitung weitergibt. Dabei erfordert ein einzelner Bogen einen anderen Saughub als eine Beilage von 120 Seiten oder ein voreingelegtes Teilprodukt. Die verschiedenen Saugantriebserfordernisse ergeben sich aus der Art, in der die Bogen oder Teilprodukte angeordnet und für die korrekte Trennung gesteuert werden müssen. Im Allgemeinen wird der Boden des Stapels von einer Plattform gehalten, einem sogenannten Signaturentisch mit einer Aussparung, die es einem Sauger ermöglicht, ein einzelnes Produkt aus dem unteren Ende des Produktstapels zu ziehen. Wenn der Sauger den Produktstapel nicht kontaktiert, wird der Stapel von einem bewegbaren Haken gehalten, wie aus der US 4,157,692 hervorgeht.A sheet separator of this type is e.g. known from US 3,988,016. This Document describes a high-speed paper loading device for loading Inserts in newspapers. The supplements are arranged so that they form a stack and a vacuum gripping element grips the lowest insert to be inserted from the stack and carries it to a pair of rollers, which passes the insert on to an open newspaper. there a single sheet requires a different suction stroke than an insert of 120 pages or a pre-loaded sub-product. The different suction drive requirements arise from the way in which the sheets or sub-products are arranged and for correct separation must be controlled. Generally the bottom of the stack is from a platform kept a so-called signature table with a recess that it a sucker allows you to pull a single product from the bottom of the product stack. If the sucker does not contact the product stack, the stack will be replaced by one movable hook held, as is apparent from US 4,157,692.
