Description

[0001] The invention relates to a processing unit, a processing machine and a method for setting up at least one suction bar of at least one processing unit according to the preamble of claim 1, claim 9 and claim 10.

[0002] In the production of packaging, web- or sheet-like materials are used. In several processing steps, the substrates are printed, embossed, grooved, perforated, punched, cut, stapled, glued, and folded into packaging. To optimally utilize the surface area of ​​a sheet-like substrate, also called a sheet, several identical or different copies, e.g., a poster, a folding box, or packaging, are usually printed on a single sheet and then punched. These copies are referred to as a "print-on-print."

[0003] A processing machine can comprise various processing steps such as printing, cutting, embossing, creasing, punching, perforating, gluing and / or stapling. Such processing machines often also have inspection devices. Sheets are usually processed and trimmed in processing machines with form-specific punching and cutting devices. Such a processing machine is designed, for example, as a punching, cutting, perforating, embossing and / or creasing machine. When such a processing machine is referred to below as a punch and / or punching machine, this also particularly refers to a cutting, perforating, embossing and / or creasing machine. In this context, form-specific systems include not only rotary punches but also flat-bed punches, in particular flatbed punches.

[0004] In flatbed die cutters, several individual sheets are processed one after the other, i.e., individually, through a cyclically repeating movement of lifting tools. The sheets are moved largely horizontally through the sheet-processing units of the processing machine, in particular a punching unit and / or stripping unit and / or blanking unit, using a transport system, preferably a chain gripper system. In addition to the punching unit, such a machine also has other units such as a sheet feeding unit, a sheet delivery unit, and / or the stripping unit. For example, a sheet insertion unit, a blanking unit, and / or a remnant delivery unit are also provided.

[0005] WO 2021 / 089291 A1 discloses a sheet processing machine comprising several lifting processing units.

[0006] DE 198 04 120 A1 relates to a device for the lateral alignment of sheets in a sheet stream during the work cycle of a sheet-processing machine. A suction-pulling rail grasps the leading sheet of a sheet stream and moves it transversely to the sheet conveying direction until it reaches a lateral alignment position. The suction-pulling rail extends across the width of the transport plane and has suction holes almost along its entire length.

[0007] The transport movement through each processing unit of the processing machine is discontinuous, with the substrate being accelerated for transport and then decelerated, remaining stationary during processing. Since the substrate is only gripped by the transport system at the front edge, the rear substrate area in particular can bulge and / or flutter during the braking process.

[0008] In order to calm the rear substrate area and hold it in its position, suction devices are arranged in front of the processing area, for example, which slow down and / or smooth and / or tighten the substrate.

[0009] WO 2024 / 003185 A1 discloses a suction bar system for a processing machine. A suction plate is mounted on a cross member. The suction plate has a plurality of air channels connected to internal air channels of the cross member.

[0010] A disadvantage of conventional suction bars, however, is that the dust generated during the individual processing steps leads to contamination and even blockage of the suction bar, particularly its openings and air ducts. This reduces or completely eliminates suction power. Furthermore, cleaning is very time-consuming. The air ducts are difficult to access. For example, depending on the degree of contamination or the substrate used, only partial cleaning is possible.

[0011] The invention is based on the object of creating a processing unit, a processing machine and a method for setting up at least one suction bar of at least one processing unit.

[0012] The object is achieved according to the invention by the features of claim 1, claim 9 and claim 10. The dependent claims show advantageous embodiments.

[0013] A processing unit is provided, particularly preferably comprising at least one lifting tool. The processing unit is particularly preferably designed for processing sheet-shaped substrates. For example, a processing machine comprising the at least one processing unit is additionally provided. A method for setting up at least one suction bar of at least one processing unit is also provided. A substrate is transported through the processing unit, preferably by means of a transport system, preferably a chain transport system.

[0014] At least one suction bar for braking and / or smoothing and / or tightening the substrate is arranged upstream of a processing area of ​​the processing unit along a transport path of the substrate. The at least one suction bar preferably extends with its longitudinal extent orthogonal to a transport direction of the substrate. The at least one suction bar has at least one suction plate. The at least one suction bar has at least one support bar on a side of the at least one suction plate facing away from the transport path. The at least one suction plate and the at least one support bar are designed to be pivotable and / or pivotable relative to one another about a pivot axis. By pivoting about the pivot axis, the surface of the at least one suction plate facing the at least one support bar and the at least one support bar are positioned and / or positioned relative to one another.Preferably, the pivoting movement adjusts the position of the at least one suction plate. A cavity configured as a suction volume is preferably formed. The at least one suction bar can preferably be converted from an open state to a closed state and / or vice versa by pivoting about the pivot axis.

[0015] The advantages achievable with the invention are, in particular, that the process reliability of the processing unit and / or the processing machine is increased. Easy handling and / or cleaning of the suction bar is advantageously enabled. The accessibility of a cavity forming a suction volume is advantageously improved, which in particular simplifies and / or improves cleaning of the suction bar. Tool-free opening of the cavity is advantageously enabled. Advantageously, for example, a suction area and the suction power therein are varied by at least one covering means. Advantageously, the suction power is adapted to a substrate format. Leakage is advantageously minimized. Further advantages can be found in the following description.

In particular, when the at least one suction bar 350 is arranged in its at least one second position, i.e. downstream along the transport path, the at least one auxiliary support device 366 supports the substrate guide 02 by limiting the transport path.When the at least one suction bar 350 is arranged in the first position in the transport direction T, i.e. in the more upstream position, the area along the transport path which is delimited by the at least one support means 367 is preferably smaller than when the at least one suction bar 350 is arranged in the at least one second position in the transport direction T, i.e. the more downstream position.

[0083] Preferably, the at least one auxiliary support device 366 is configured such that the at least one support means 367 continues a transport plane that is or will be formed by the surface of the at least one suction plate 351 facing the transport path of substrate 02, i.e., by the suction surface 352.
