Definitions

the invention relates to a feed table for cyclical conveying of sheets to a sheet processing Machine, with a table surface over which one or more spaced apart, extending in the conveying direction and transporting the sheets Suction belts drivable in the conveying direction are guided, the suction belts being endless are and the feed table over in the takeover and Enclose deflection rollers arranged in the transfer area, as well as distributed over their entire length with continuous Suction openings are provided and the bottom the suction tapes can be pressurized.
the holding force is different depending on the extent of the cover of the suction openings through the arch.
the object of the invention is therefore a feed table to create of the type mentioned by which the Sheet at each point on the feed table with the optimal holding force can be held on the suction belts.
This object is achieved in that under one or more suction belts in the conveying direction a large number of pressurizable and / or negative pressure pressures Application areas arranged are, the pressure and / or negative pressure can be controlled separately.
This training enables the holding force with which the sheets on the suction belts are held on everyone Adjust the position of the feed table to an optimum. Doing so may require a high area Holding force in which a vacuum is applied, to suddenly reach a low holding force according to exposure areas with high negative pressure Areas of application with less Pressurized or even pressurized consequences. This is e.g. in the end area of the feed table beneficial in a side orientation should take place, which is a shift of the to be aligned Bow required while the immediately following bow still held immovable on the suction belts Need to become.
the pressure and / or negative pressure application of the application areas can depend on their coverage be controlled by promoted sheets, so that vacuum or pressure losses due to short circuit with the atmosphere and thus a change in the holding power of the Bow on the coffin tapes is avoided.
the application areas can be with a pressure and / or Different pressure levels can be applied to negative pressure be controllable.
a simple design of the application areas is that the areas of exposure to arranged under the table surface pressure and / or pressurizable chambers are formed which through openings in the table surface with the bottom the suction belts are connected.
Each application area can be controlled separately Fan for pressurizing and / or negative pressure be assigned or each area of application is via a separately controllable valve connectable to a pressure and / or vacuum source.
the feed table shown in the figures has one On table surface 1, in the direction of conveyance 2 extending and spaced apart suction belts 3 are led, one of which is shown.
the suction belts 3 are designed as endless suction belts 3 and enclose the feed table so that they via first deflection rollers 4 on the feed side and Delivery side of the feed table to that of the table surface 1 facing away from the bottom and there via further arranged on the supply side and delivery side Roll 5 run.
Deflection rollers 4 and rollers 5 are at right angles to the conveying direction 2 extending axes rotatable, the discharge-side deflection rollers 4 are rotatably drivable and for a movement of the on the table surface 1 provide suction belts 3 in the conveying direction 2.
On the underside of the table surface 1 are in the area a plurality of chambers 6 under the suction belts 3 arranged in the conveying direction 2 one behind the other Passages 7 in the table surface 1 with the bottom the suction belts 3 are connected.
the passages 7 form areas of exposure.
the chambers 6 are lined up directly, whereby the passages 7 have a distance from each other, the about the smallest possible scale spacing supporting scale flow from Bogen corresponds.
a fan 8 is arranged in each chamber 6 is reversibly driven and depending on the direction of rotation generates a pressure or a negative pressure in the chamber 6. By controlling the fans 8 with higher or lower speed can be different Pressure level in the chambers 6 are generated.
the chamber has an opening leading to the outside, whose passage cross section is variable between fully closed and fully open adjustable is. Due to the short circuit to the outside air is despite constant Speed of the fans an adjustment of the Pressure levels in the chambers possible.
each fan 8 in the illustrated embodiment can be taught separately, is in everyone Chamber 6 separately generate a pressure or negative pressure.
