Description

The invention relates to a sheet processing machine and a method for transporting sheets in a sheet processing machine according to the preamble of claim 1 and claim 14.

Materials in the form of webs or sheets are processed in the manufacture of packaging. In several processing steps, the sheets are printed, embossed, creased, perforated, punched, cut, stapled, glued and folded into packaging, for example. For optimal utilization of the area of a sheet, several identical or different copies, e.g. B. a poster, a folding box or packaging, printed on a common sheet and then punched. These specimens are referred to as panels.

A sheet processing machine can have various processing steps such as printing, cutting, embossing, creasing, punching, perforating, gluing and/or stapling. Such sheet processing machines often also have inspection devices. Sheets are usually processed and trimmed in processing machines with form-bound punching and cutting devices.

Such a processing machine is designed, for example, as a punching, cutting, perforating, embossing and/or creasing machine. If such a processing machine is referred to below as a punch and/or punching machine, this also means in particular a cutting, perforating, embossing and/or creasing machine. In the case of form-bound systems, in addition to rotary die-cutting, there are also flat die-cutting, in particular flat-bed die-cutting.

Rotary punching machines can, for example, be equipped with the modules punching unit, creasing unit, embossing unit and stripping unit. Such a rotary punch is, for example, from WO 2017/089420 A2 known.

Transport cylinders, for example, are provided to guide sheets through the units of the rotary die cutter. A sheet is held on a transport cylinder, for example, by means of a gripper system. Alternatively, the sheet is held on the transport cylinder, for example by negative pressure.

through the WO 2018/028 980 A1 a suction cylinder is known. Suction cups arranged axially with respect to one another on the cylinder hold the leading edge or trailing edge of a sheet. However, the holding force of the suction cups, which hold the sheet at the leading edge or trailing edge, is too low, which is why an additional suction surface along the lateral surface of the cylinder is necessary.

The object of the invention is to provide a sheet processing machine and a method for transporting sheets in a sheet processing machine.

The object is achieved according to the invention by the features of claim 1 and claim 14.

A sheet processing machine preferably has at least one impression cylinder. The at least one impression cylinder preferably has at least one holding means designed as a suction cup. The at least one suction cup preferably has at least one spatial area designed as a suction area. At least one support element is preferably arranged within the at least one suction area.

Sheets are preferably transported in the sheet processing machine. The at least one sheet is preferably held on an impression cylinder by at least one holding means designed as a suction cup. During transport, the at least one sheet preferably rests on at least one support element arranged within at least one suction area of the at least one sucker.

The at least one sheet is preferably drawn onto the at least one sucker by means of the suction force. The at least one arc preferably rests on an outer contour of an entry surface. The at least one support element is preferably lowered in relation to the entry surface.

The at least one suction cup is advantageously designed to hold sheets of different materials to be processed, in particular independently of their grammage and/or basis weight and/or thickness, on the impression cylinder. Both a sheet of cardboard and/or cardboard and a sheet of paper and/or foil and/or thin printing paper are advantageously held on the impression cylinder by means of the at least one suction cup. Advantageously, the at least one suction cup is designed universally, in particular independently of the material properties of the at least one sheet, to hold the at least one sheet on the impression cylinder. The flexibility of using the sheet processing machine is preferably increased.

An effective suction area is preferably varied according to the sheet to be processed. Depending on the nature of the at least one sheet, for example its weight per unit area, particularly in the case of rigid and/or thick materials, an effective suction area preferably results from the entry area minus the contact area of the outer contour. Preferably, the holding force, preferably called the suction force, is thus maximized, preferably with a constant suction power of the teat. Depending on the nature of the at least one sheet, for example its weight per unit area, particularly in the case of limp and/or thin materials, the at least one sheet is pulled into the suction area of the at least one suction cup. For example, a lower holding force is sufficient for this arch than for the rigid arch, for example. For example, this results in a deformation and/or loading of the at least one sheet. The at least one support element preferably prevents deformation and/or loading of the at least one sheet. The at least one support element preferably reduces the effective suction area and thus preferably the suction force applied to the at least one sheet.

The suction force, preferably the effective suction area, of the at least one suction cup, preferably of at least two suction cups in at least one suction cup bar, is advantageously sufficient to hold the at least one sheet on the impression cylinder. Advantageously, an additional suction surface in the area of at least one field of the impression cylinder can be minimized or omitted. Advantageously, the lateral surface of the impression cylinder within the at least one field is provided with at least one function that differs from sucking in the at least one sheet, for example processing the at least one sheet with at least one tool.

At least one stripping unit of a forming unit of the sheet processing machine preferably has the at least one impression cylinder with the at least one suction cup. Since the at least one impression cylinder has at least one tool plate in addition to the at least one suction cup, the limited installation space is preferably optimally utilized by using the at least one suction cup. In particular in comparison to holding means designed as grippers for holding the at least one sheet, space is preferably saved.

Such a processing machine is particularly advantageous for the production of packaging materials, preferably sheets for the production of folding boxes or labels, because different sheets with different material thicknesses can be processed. The sucker, which is arranged on the impression cylinder and can be used for materials of different thicknesses, advantageously leads to flexible and economical production of packaging materials.

Further advantages can be seen from the following description.
