Description

The invention relates to a processing machine according to the preamble of claim 1 and a method for adjusting at least one conveying means of a processing machine according to the preamble of claim 14. Packaging is manufactured using web- or sheet-shaped materials. In several processing steps, the sheets are printed, embossed, creased, perforated, die-cut, cut, stapled, glued, and folded into packaging. To optimally utilize the surface area of a sheet, several identical or different copies, such as a poster, a folding box, or a package, are typically printed on a single sheet and then die-cut. These copies are referred to as a unit. A processing machine can include various processing steps such as printing, cutting, embossing, creasing, die-cutting, perforating, gluing, and/or stapling. Such processing machines often also feature inspection devices. Sheets are typically processed and trimmed in processing machines with form-based die-cutting and cutting units. Such a processing machine is, for example, a die-cutting, cutting, perforating, embossing, and/or creasing machine. When such a processing machine is referred to as a die-cutting and/or stamping machine in the following, this specifically includes a cutting, perforating, embossing, and/or creasing machine. In form-based systems, there are both flatbed and rotary die-cutting machines. Due to the continuous motion process, rotary die-cutting machines can achieve significantly higher production speeds than flatbed die-cutting machines. Rotary die-cutting machines are equipped, for example, with modules such as a die-cutting unit, a creasing unit, an embossing unit, and/or a stripping unit. One such rotary die-cutting machine is, for example, made from the WO 2017/089420 A2 known. Individual substrates are processed between interacting machining cylinders of machining units and then collected in a display to form a stack of substrate. Through the WO 2021/233667 A1 A process for panel separation is known, wherein the separation of partial stacks of substrate takes place inline with upstream forming units. After the panel separation process, the resulting partial stacks of panels are conveyed from the panel separation area by a rake and laid out in a panel display in the form of panel stacks. The DE 10 2013 214 531 A1 A sheet-processing machine with a feeder or delivery unit containing a sheet support element with a support structure for receiving at least one sheet section is taught. The support structure can be positioned under the sheet to be received. A traction element can be stored in the support structure in such a way that the insertion of the support structure occurs without relative movement between the traction element and the sheet to be received. The invention is based on the objective of creating a processing machine and a method for adjusting at least one conveying means of a processing machine. The problem is solved according to the invention by the features of claim 1 and claim 14. The dependent claims represent particularly advantageous embodiments of the solution found. A processing machine and/or a method for adjusting at least one conveying element of a processing machine is provided. The processing machine preferably has at least one processing unit, preferably with at least one movable tool. The at least one processing unit is preferably a blanking unit. The at least one processing unit preferably has at least two support elements designed for supporting the substrate and/or the blank.

The at least one conveying element preferably has a first position and at least one further position in the longitudinal direction of the at least one tine, wherein the at least one tine in the first position of the at least one conveying element is arranged between the at least two support elements of the at least one processing unit, and wherein the at least one tine in the further position of the at least one conveying element is arranged outside the at least one processing unit. The at least one conveying element is preferably adjusted in the longitudinal direction of the at least one tine from the further position to the first position. The at least one tine is and/or is preferably flexibly mounted and/or designed within the at least one conveying means. Advantageously, deformation and/or bending of the support elements is prevented, especially when at least of an obstacle in the movement path of at least one tine.
