摘要:
The invention relates to a machine for processing sheet members (10), including chain sets (80) and at least one tensioning device (50) that generates a tensile force in said chain sets. According to the invention, the chain-set tensioning device includes a driving member (51) capable of generating a variable force (Fv), the intensity of which depends on the instantaneous pace of the machine. The wear of the chain sets (80) can be substantially reduced, and the lifespan thereof is substantially lengthened.

The invention relates to an apparatus and a method for compiling flat objects. According to the invention, a gripper conveyor is used, the grippers of which (12) either act directly as support elements (20) or contact surfaces (22) for the products (100) to be compiled, thereby constituting a receiving unit (10), or interact with a separate support element (20) to form a receiving unit (10). The use of a gripper conveyor having a controllable opening state and a controllable orientation of the gripper jaws (14, 16) of the individual grippers (12), and/or a controllable orientation of the separate support elements (20), has the advantage that the orientation of the contact surfaces and the clamping function within a receiving unit (10) can be set independently of the adjoining receiving units (10). In this way, greater flexibility is attained.

The invention relates to a device and a method for inserting flat objects (5) into a folded printed product (2), wherein the products (2) are held by grippers (12) of a gripper conveyor (10) which opens only briefly for inserting the flat object (5). In order to also stabilize the product in the open state of the gripper (12), according to the invention a support element (22, 22') is provided, which moves between the two product parts (3, 4) before the gripper (12) opens and rests on one of the product parts (3, 4). If the orientations of the support elements (22, 22') and the grippers (12) are selected in a suitable fashion, this will suffice in order to position the product (2) and keep it open such that the flat object (5) can be inserted and the gripper (12) can then be closed again, while clamping the product (2) with the flat object (5) into position. Optionally, further support elements (62, 62', 70) are present, which additionally support the product (2) from the outside, such as the folded edge (6).
摘要:
It is known for die cutting and embossing machines to transport gripper devices through the machine by means of two chains. The gripper devices are connected at the ends thereof to the chains. The chains and gripper devices are supported in guide tracks, in which sliding rails are disposed. In known die cutting and embossing machines, the sliding rails are cast into the guide tracks, constituting a high degree of exchanging complexity. The aim of the invention is therefore to ensure high heat dissipation, low installation height, and low-wear chain guidance. This aim is achieved in that grooves having a rectangular cross-section are integrated in the guide tracks in the region of the chain and guide paths, and that the sliding rails for the chain and guide paths are separated and have a T-shaped cross-section, wherein the webs of the sliding rails are inserted in the grooves.

Die Druckereiprodukte (24) werden mittels Aufnahmeelementen (32) der Verarbeitungseinrichtung (12) der Wegführstation (16) zugeführt. Diese weist einerseits einen Entnahmeförderer (18) und andererseits einen bezüglich diesem in Umlaufrichtung (U) der Aufnahmeelemente (32) stromabwärts angeordneten Klammertransporteur (20) auf. Die Greiferzangen (22) des Entnahmeförderers (18) ergreifen die Druckereiprodukte (24) bei der Seitenkante (26) und fördern diese aus den Ausnahmeelementen (32) heraus. Die jeweils nachlaufende Wand (36) jedes Aufnahmeelements (32) ist mit einem Führungselement (50) versehen, welches das betreffende Druckereiprodukt (24) jeweils stützt und in eine geöffnete Klammer (28) des Klammertransporteurs (20) einführt. Die Klammern (28) erfassen die Druckereiprodukte (24) beim Rand (30), mit welchem die Druckereiprodukte (24) vorgängig am Boden (42) der Aufnahmeelemente 32) anlagen.
