[0003] DE 30 04 701 A1 discloses a processing machine whose drive system comprises a transmission with both intermeshing gears and a toothed belt. The transmission has several transmission paths that can be separated from the rest of the transmission by means of clutches.

[0004] DE 101 55 033 A1 describes a gear that ensures that sheet transfers between gripper bridges and grippers of cylinders take place correctly.

[0005] DE 197 54 544 C1 discloses a drive arrangement for a web-fed rotary printing press, wherein, in addition to a gear train formed from gears, a toothed belt is provided which transmits torque between gears of the gear train in the same direction as the gear train itself and which serves to ensure a drive of the corresponding cylinders even when the cylinders are spaced apart from one another.

[0006] The invention is based on the object of creating a sheet processing machine with a sheet transport device.

[0007] The object is achieved according to the invention by the features of claim 1.

[0008] 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. The at least one sheet transport device is assigned a plurality of, in particular parallel, transport rotation axes. Each transport rotation axis is assigned at least one respective transport body, which is arranged to be rotatable about the respective transport rotation axis. Each of these transport rotation axes is assigned at least one, and preferably exactly one, transport gear. The at least one sheet transport device is assigned a plurality of transmission rotation axes. Each transmission rotation axis is assigned at least one, and preferably exactly one, transmission gear.The transmission gears, together with the transport gears, form a torque-transmitting gear train, wherein at least one and preferably exactly one transport rotation axis or at least one and preferably exactly one transmission rotation axis is designed as a torque-input drive axis of the gear train. The sheet transport device has at least one first tensioning device. One of the transport rotation axes is designed as the first tensioning axis of the first tensioning device. One of the transport rotation axes is designed as the second tensioning axis of the first tensioning device. At least one of the transport rotation axes is designed as a first intermediate axis and is arranged along the gear train between the first tensioning axis of the first tensioning device and the second tensioning axis of the first tensioning device.The first tensioning device has at least one, and preferably exactly one, tensioning element designed as a chain or belt, in particular a toothed belt. The at least one tensioning element of the first tensioning device connects the first tensioning axis of the first tensioning device to the second tensioning axis of the first tensioning device in a torque-transmitting manner, bypassing the at least one first intermediate axis, in particular bypassing the remaining gear train. An advantage of this sheet processing machine is that gear play in the gear train can be prevented, allowing the transport bodies to rotate synchronously. This increases the precision of the transport of the respective sheet.

[0009] In a further development, the sheet processing machine is preferably characterized in that at least one tensioning device of the first bracing device is arranged to act on the at least one bracing element of the first bracing device. Tooth play can then be prevented even in the long term, for example, even when the material of the bracing element ages.

[0010] In an alternative or additional development, the sheet processing machine is preferably characterized in that the tensioning device of the first bracing device has a movable first contact body, which is designed, for example, as a roller, and in that a position of a center of gravity of this first contact body relative to the bracing axes is adjustable, in particular by means of at least one first lever pivotable about a first pivot axis. This allows a precise adjustment of the torque produced by the bracing device.

[0011] In an alternative or additional development, the sheet processing machine is preferably characterized in that a drive torque is exerted and / or can be exerted on the second bracing axis of the first bracing device by means of the gear train, and in that the bracing element exerts a bracing torque on the second bracing axis of the first bracing device, and that this bracing torque is directed oppositely to this drive torque and / or counteracts this drive torque. Due to the opposing torques, all tooth flanks of the gear train are pressed together even in the event of torque fluctuations, thereby preventing tooth play.

[0012] In an alternative or additional development, the sheet processing machine is preferably characterized in that the at least one sheet transport device comprises at least one suction transport means and / or upper suction transport means and / or roller suction system. This allows sheets to be transported particularly precisely and, if necessary, even in a suspended position.

This allows, for example, sufficient space to be provided for air flows of the suction transport means, and the sheets can be supported at a plurality of points distributed across their width. This enables reliable sheet transport.

[0014] In an alternative or additional development, the sheet processing machine is preferably characterized in that the transport rotation axes are arranged parallel to each other.

[0015] In an alternative or additional development, the sheet processing machine is preferably characterized in that the respective sheet transport device is assigned in particular exactly one transport drive, which is arranged to introduce torque into the gear train via the drive axle and which is preferably designed as a position-controlled electric motor.

[0016] 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 tensioning device and that one of the transport rotation axes is designed as the first tensioning axis of the second tensioning device and that one of the transport rotation axes is designed as the second tensioning axis of the second tensioning device and that at least one of the transport rotation axes is designed as a second intermediate axis and is arranged along the gear train between the first tensioning axis of the second tensioning device and the second tensioning axis of the second tensioning device and that the second tensioning device has at least one and preferably exactly one chain or belt, in particular toothed belt,formed tensioning element, and that the at least one tensioning element of the second tensioning device connects the first tensioning axis of the second tensioning device to the second tensioning axis of the second tensioning device in a torque-transmitting manner, bypassing the at least one second intermediate axis, in particular bypassing the remaining gear train. The transport drive can then introduce the torque relatively centrally into the gear train. In an alternative or additional development, the sheet processing machine is preferably characterized in that the drive axis is a transmission rotation axis and / or that the drive axis is arranged along the gear train between the first tensioning axis of the first tensioning device and the first tensioning axis of the second tensioning device.

A circumferential movement of the at least one conveyor belt 726 then results in a forward movement of the transport surface 717, with sheets 02 being held securely on the transport surface 717 precisely in the region in which they lie opposite the suction opening 722 covered by the at least one conveyor belt 726 with the exception of the suction openings 723.

The suction openings 722 are then preferably designed in the shape of a frame and each surround at least one of the transport rollers 724 and / or transport cylinders 724. A circumferential movement of the transport rollers 724 and / or transport cylinders 724 then results in a forward movement of the corresponding parts of the transport surface 718, with sheets 02 being held securely on the transport surface 718 precisely in the area in which they lie opposite the suction openings 722. (This is also shown schematically in FIG. Fig. 2b.)
