Description

The invention relates to a sheet processing machine with a sheet transport device.

through the DE 10 2019 104 173 B3 a sheet processing machine with at least one sheet transport device is known, which has a plurality of transport axes of rotation with respective associated transport bodies, the transport bodies being driven by means of a common drive.

The object of the invention is to create a sheet processing machine with a sheet transport device.

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

A sheet processing machine has at least one sheet transport device, which is arranged along a transport path provided for the transport of sheets, in particular between a substrate feed device and a sheet delivery device. The at least one sheet transport device is assigned a plurality of, in particular, parallel transport rotation axes. Each transport axis of rotation is assigned at least one respective transport body, which is arranged such that it can rotate about the respective transport axis of rotation. Each of these transport axes of rotation is assigned at least one and preferably precisely one transport gear wheel. A plurality of transfer axes of rotation is assigned to the at least one sheet transport device. Each transmission axis of rotation is assigned at least one and preferably precisely one transmission gear. The transmission gears together with the transport gears form a torque-transmitting gear train, with at least one and preferably exactly one transport axis of rotation or at least one and preferably exactly one transmission axis of rotation being designed as a torque-driving drive axis of the gear train. The sheet transport device has at least one first bracing device. One of the transport rotation axes is designed as the first bracing axis of the first bracing device. At least one of the transport rotation axes is designed as a first intermediate axis and is arranged along the wheel train between the first bracing axis of the first bracing device and the second bracing axis of the first bracing device. The first bracing device has at least one and preferably exactly one bracing element designed as a chain or belt, in particular a toothed belt. The at least one bracing element of the first bracing device connects the first bracing axis of the first bracing device in a torque-transmitting manner, bypassing the at least one first intermediate axis, to the second bracing axis of the first bracing device, in particular bypassing the remaining gear train. An advantage of this sheet processing machine is that a gear wheel play in the wheel train can be prevented and the transport bodies thereby rotate synchronously. This increases the precision of the transport of the respective sheet.

In a development, the sheet processing machine is preferably characterized in that at least one tensioning device of the first tensioning device is arranged to act on the at least one tensioning element of the first tensioning device. Backlash can then also be prevented in the longer term, for example even when the material of the bracing element ages.

In an alternative or additional development, the sheet processing machine is preferably characterized in that the clamping device of the first bracing device has a movable first contact body, which is designed as a roller, for example, and that a position of a center of gravity of this first contact body can be adjusted relative to the bracing axes, in particular by means of at least one first lever pivotable about a first pivot axis. A precise setting of the torque caused by the bracing device can then be achieved.

In an alternative or additional development, the sheet processing machine is preferably characterized in that a drive torque is and/or can be exerted on the second bracing axis of the first bracing device by means of the gear train and that the bracing element exerts a bracing torque on the second bracing axis of the first bracing device and that this tension torque is directed in the opposite direction to this drive torque and/or counteracts it. Due to the opposing torques, all tooth flanks of the gear train are pressed together even with torque fluctuations, thus preventing backlash.

In an alternative or additional development, the sheet processing machine is preferably characterized in that the at least one sheet transport device has at least one suction has transport means and/or upper suction transport means and/or roller suction system. Then sheets can be transported particularly precisely and, if necessary, also hanging.

In an alternative or additional development, the sheet processing machine is preferably characterized in that at least one and preferably each transport axis of rotation is assigned a transport shaft, on which several transport bodies are arranged spaced apart from one another, in particular in the transverse direction, and/or that the transport bodies are designed as respective transport rollers or transport cylinders are. Then, for example, sufficient space can be provided for air flows of the suction transport means and the sheets can be supported at a plurality of points distributed over their width. This enables safe sheet transport.

In an alternative or additional development, the sheet processing machine is preferably characterized in that the transport rotation axes are arranged parallel to one another.

In an alternative or additional development, the sheet processing machine is preferably characterized in that the respective sheet transport device is assigned precisely one transport drive, which is arranged to introduce torque into the gear train via the drive axle and is preferably designed as a position-controlled electric motor.

In an alternative or additional development, the sheet processing machine is preferably characterized in that the at least one sheet transport device has at least one second bracing device and that one of the transport rotation axes is designed as the first bracing axis of the second bracing device and that one of the transport rotation axes is designed as the second bracing axis of the second bracing device and that at least one of the transport rotation axes is designed as a second intermediate axis and is arranged along the wheel train between the first bracing axis of the second bracing device and the second bracing axis of the second bracing device, and that the second bracing device has at least one and preferably precisely one chain or belt, in particular a toothed belt Has bracing element and that the at least one bracing element of the second Verspanneinrich device connects the first bracing axis of the second bracing device in a torque-transmitting manner, bypassing the at least one second intermediate axis, in particular bypassing the remaining wheel train, to the second bracing axis of the second bracing device. Then the transport drive can introduce the torque relatively centrally into the wheel train. In an alternative or additional development, the sheet processing machine is preferably characterized in that the drive axle is a transmission axis of rotation and/or that the drive axle is arranged along the gear train between the first bracing axle of the first bracing device and the first bracing axle of the second bracing device.

A processing machine 01 is preferably embodied as a printing machine 01 and/or as a shaping machine 01, in particular a punching machine 01. Printing press 01 is embodied as a flexographic printing press 01, for example.

Processing machine 01 is preferably referred to as printing machine 01 if it has at least one printing unit 614 and/or at least one printing unit 600, in particular regardless of whether it has other units for processing substrate 02. For example, a processing machine 01 embodied as a printing press 01 also has at least one further unit 900, for example at least one shaping unit 900, which is preferably embodied as a punching unit 900. Processing machine 01 is preferably referred to as a shaping machine 01 if it has at least one shaping mechanism 914 and/or at least one shaping unit 900, in particular regardless of whether it has other units 600 for processing substrate 02. Processing machine 01 is preferably referred to as a punching machine 01 if it has at least one punching unit 914 and/or at least one punching unit 900, in particular regardless of whether it has other units 600 for processing substrate 02. For example, a processing machine 01 embodied as a shaping machine 01 or punching machine 01 also has at least one further unit 600 for processing substrate 02, for example at least one printing unit 600 and/or at least one printing unit 614. If processing machine 01 has at least one printing unit 614 and/or at least a printing unit 600 on the one hand and at least one shaping unit 914 and/or at least one shaping unit 900 on the other hand, it is therefore configured both as a printing press 01 and as a shaping machine 01. If processing machine 01 has at least one printing unit 614 and/or at least one printing unit 600 on the one hand and at least one punching unit 914 and/or at least one punching unit 900 on the other hand, it is therefore configured both as a printing machine 01 and as a shaping machine 01, in particular a punching machine 01.

The processing machine 01 is preferably embodied as a sheet-fed processing machine 01, i.e. as a processing machine 01 for processing sheet-type substrate 02 or sheets 02, in particular sheet-type printing material 02. For example, the sheet-fed processing machine 01 is configured as a sheet-fed printing machine 01 and/or as a sheet-forming machine 01 and/or as a sheet-fed punching machine 01 educated. The processing machine 01 is further preferably embodied as a corrugated cardboard sheet processing machine 01, i.e. as a processing machine 01 for processing sheet-shaped substrate 02 or sheets 02 made of corrugated cardboard, in particular sheet-shaped printing material 02 made of corrugated cardboard. Processing machine 01 is also preferably configured as a sheet-fed printing machine 01, in particular as a sheet-fed corrugated board printing machine 01, i.e. as a printing machine 01 for coating and/or printing on sheet-type substrate 02 or sheets 02 made of corrugated board, in particular sheet-type printing material 02 made of corrugated board. For example, printing press 01 is embodied as a printing press 01 that operates according to a printing form-based printing process.

Unless an explicit distinction is made, the term sheet-shaped substrate 02, in particular a printing material 02, specifically sheet 02, is used here to mean any flat substrate 02 or any substrate 02 that is present in sections, i.e. also substrates 02 that are in the form of panels or plates, i.e. also panels or plates, be included. The sheet-like substrate 02 or sheet 02 defined in this way is made of paper or cardboard, for example; H. formed as paper or cardboard sheets, or by sheets 02, panels or plates made of plastic, cardboard, glass or metal. The substrate 02 is more preferably corrugated cardboard 02, in particular corrugated cardboard sheets 02. The thickness of a sheet 02 is preferably understood to mean a dimension orthogonal to a largest area of the sheet 02. This largest area is also referred to as the main area. The thickness of the sheets 02 is, for example, at least 0.1 mm, more preferably at least 0.3 mm and even more preferably at least 0.5 mm. In the case of sheets of corrugated cardboard 02 in particular, significantly greater thicknesses are also common, for example at least 4 mm or even 10 mm and more. Corrugated cardboard sheets 02 are comparatively stable and therefore not very flexible. Corresponding adjustments to the processing machine 01 therefore make it easier to process thick sheets 02.

A unit is preferably understood to mean a group of devices that work together functionally, in particular to be able to carry out a preferably self-contained processing operation on sheets 02. For example, at least two and preferably at least three and more preferably all of the units 100; 300; 600; 700; 900; 1000 as modules 100; 300; 600; 700; 900; 1000 formed or at least assigned to one such. A module is to be understood in particular as a respective unit or a structure made up of several units, which preferably has at least one means of transport and/or at least one controllable and/or regulatable drive of its own and/or as an independently functioning module and/or each manufactured separately and/or is formed as a machine unit or functional assembly mounted on its own. A separate controllable and/or regulatable drive of a unit or module is to be understood in particular as a drive which is used to initiate movements of components of this unit or module drive and/or which serves to transport substrate 02, in particular sheets 02, through this unit or module in question and/or through at least one effective area of this unit or module in question and/or which serves to ensure at least one contact with Arc 02 intended component of the respective unit or module to drive directly or indirectly. These drives of the assemblies of processing machine 01 are preferably designed as position-controlled electric motors in particular.

Each unit preferably has 100; 300; 600; 700; 900; 1000 at least one drive controller and/or at least one drive controller, which is assigned to the respective at least one drive of the respective unit.

The drive controls and/or drive controllers of the individual units 100; 300; 600; 700; 900; 1000 are and/or can be linked to one another and/or to a machine controller of processing machine 01 in terms of circuitry, in particular by means of at least one BUS system, in such a way that coordinated control and/or regulation of the drives of several or all units 100; 300; 600; 700; 900; 1000 of processing machine 01 is and/or can be carried out.
