Definitions

the invention relates to a sheet brake in the boom of a printing press according to the preamble of the main claim.
a bow brake of this type is known from DE 2 811 963 C2.
the sheet brake is designed as a suction roll with built-in suction chambers and integrated suction air supply.
the suction rolls are driven by separate drive wheels.
a separate suction body with suction air supply can be plugged onto the suction rolls, which is supported on a crossbar.
the complete suction rolls are interchangeable depending on the operating mode (fine or reverse printing) with a narrow or wide version.
the suction roller has recesses running radially to the side of the peripheral surface and an air outlet opening arranged in the upper segment area of the suction roller.
a disadvantage of the above-mentioned solutions is that a complete change of the suction roller is necessary when changing from perfecting to reverse printing, when changing to another printing material or when worn. This requires downtimes and requires more effort.
A1 another bow brake is known which has suction bodies axially adjustable on a carrier shaft.
the suction body has suction nozzles on the circumference, which are used for a short time Suction air can be acted upon.
the carrier shaft has a longitudinally arranged control slot for the suction air and a concentrically rotatable, axially immovable perforated suction body tube arranged thereon.
Radially pluggable suction body segments are arranged concentrically on the suction body tube and bellows surrounding the suction tube in the axial direction are arranged between the suction body segments.
the object of the invention is to develop a solution that allows a quick change of the sheet brake and ensures a sufficient braking effect with all substrates and operating modes.
suction ring element allows the suction ring element to be changed quickly without completely changing the suction roller.
suction ring elements of different widths can be placed concentrically on a roller base. In the event of wear, it is only necessary to replace the suction ring element.
the delivery stack of a sheet delivery is preceded by a drive shaft 1 mounted in the side frame walls in the conveying direction 14 of a chain system 13.
a traverse 2 is arranged parallel to the drive shaft 1 transversely to the conveying direction 14 and is likewise fixed in the side frame walls.
a sheet brake essentially consists of a suction roll base body 6 which is positively fixed on the drive shaft 1 and which is accommodated in a housing 3, the housing 3 being detachably connected to the cross member 2. In the present example, this is carried out by a clamp connection 8.
the housing 3 extends laterally around the suction roll base body 6 through two side walls 7. With a corresponding design of the suction roll base body 6, the housing 3 can also have only one side wall 7.
a suction channel 5 runs around each side wall 7, which is guided laterally to the suction roll base body 6 and is coupled in the housing 3 to a suction air line 4.
the suction roll base body 6 has radial lateral openings 11 which are coupled to openings 10 emerging on the circumference.
a suction ring element 9 is arranged concentrically with the suction roller base body 6.
the suction ring element 9 has through bores 12 emerging radially on the circumference, which are approximately coincidentally fixed with the openings 10 of the suction roll base body 6. This is achieved, for example, by a positive connection, through which the through bores 12 are positioned to the openings 10.
the suction ring element 9 consists of at least two parts 9.1; 9.2. Both parts 9.1; 9.2 are detachably connected.
a simple connection can be achieved by an approximately U-shaped clip as a connecting element 16, which in axial bores of the suction ring element 9 or in its parts 9.1; 9.2 this intervenes.
Other preferred connection options are e.g. a swivel and a releasable snap connection or two releasable snap connections. When using a multi-part suction ring element 9, the number of connection points increases accordingly.
a suction ring element 9 with a wider sheet support surface 17 is used (FIG. 4).
a suction ring element 9 with a narrower arch supporting surface 17 is used for sheets 15 produced in reverse or face and reverse printing, which slopes away conically on the side surfaces of the suction ring element 9.
the wider suction ring element 9 according to FIG. 4 can also be used if there is sufficient space.
the two-part or multi-part design of the suction ring element 9 enables a quick change by the operator with little effort.
