Definitions
- the invention relates to a device for feeding sheets, with a sheet separator for separating the sheets from a stack in cycles and with suction cups for transporting the sheets to a belt table.
- Such devices are used in particular in connection with sheet processing machines or as a component of sheet processing machines. In connection with uses in sheet processing machines that are designed as printing machines, they are also referred to as feeders.
- a method for controlling the sheet feed to a sheet processing machine with a sheet feeder which has, inter alia, a sheet separator for separating the sheets from a stack and a belt table or suction belt table.
- the sheets are transported to the machine and checked for double, missing or crooked sheets. If such a sheet is present or in the event of malfunctions in the downstream machine, the sheet feed is stopped, with a scanning device detecting the height of the stack being provided and the sheet feeder being driven by individual drives that are operated by means of processing electronics that are linked to a control device of the downstream machine is to be controlled
- EP 1 281 647 B1 presents a method for conveying sheets in a sheet feeder of a sheet processing machine.

- a feeder which comprises several components for influencing the sheet, which drives can be controlled independently of one another assigned.
- the components include a sheet separator, which is used to separate the sheets from a stack of sheets, a suction belt table, which is used to transport the sheets in scaled form, and a flap shaft.
- Each of the components has an individual drive.
- the empty run of the suction belts used lies on the sheet-transporting table surface, while the load run is on the underside of the belt table.
- the suction belts and the sheet relay resting on them are pushed, which has a detrimental effect on the conveying accuracy.
- DE 102009046 089 A1 discloses a sheet feeder of a sheet processing machine, the sheet feeder having a sheet source, a sheet separator, a conveyor belt and an alignment unit connected downstream of the conveyor belt.
- the transport speed of the conveyor belt is controlled as a function of a measurement signal from a sheet arrival sensor.
- the invention is based on the object of creating a device for feeding sheets in which the sheets are transported with greater accuracy, in particular with greater uniformity.
- the advantages that can be achieved with the invention are, in particular, that fluctuations in the distances between the sheets in the sheet relay are reduced and the sheet arrival for each individual sheet at the end of the transport path of the suction belt table can be realized exactly at the specified time.
- a change in the elasticity or the length of the suction belt which can occur when the suction belt ages, no longer affects the transport of the sheets, or only does so to a lesser extent.

- an increased speed of the fifth drive 23 of the sheet separator 7 and / or the suction device and an increased speed of the second drive 24 on the sheet flap compared to the conveyor belt 14 can cause the sheet leading edge subsequent sheets arrive earlier at the processing plant.
- the length of the scales between the arches is reduced.
- the control can react to an early sheet in a corresponding manner, with the difference that the speed of the fifth drive 23 and the second drive 24 is reduced and the shingle length, that is, the distance between the leading edges of the sheets, is increased.
