Definitions
- the invention relates to a device for cross-cutting webs of material, in particular paper or board webs, comprising a cross-cutting device comprising two knife drums equipped with transverse knives and a sheet transport device arranged behind the cross-cutting device, which device contains a braking device with a brake roller.
- Cross-cutting devices that produce individual sheets from a paper or board web by cross-cutting, which are then deposited on a stack, known manner behind the cross cutter a sheet transport device containing a braking device with freely rotatable brake rollers.
- a sheet transport device containing a braking device with freely rotatable brake rollers.
- the invention is therefore an object of the invention to improve a generic cross-cutting device so that even on sensitive paper or cardboard grades markings are avoided on the sheets.
- brake roller (s) is resiliently mounted and movable upwards by the force of an incoming sheet (are).
- the resilient mounting of the brake rollers makes it possible to apply the required to decelerate the arches contact force exactly metered.
- the brake rollers can move upwards and adjust their position so the step-shaped course of the top of the scaled conveyed arcs or bow packages.
- the nip force acting on the sheets or sheet packets in the catch nip between the brake rollers and the lower conveyor, on which the sheets rest, remains essentially constant during the passage.
- claims 5,6, 8 and 9 are used individually and in combination to produce as large a contact surface between the brake rollers and the sheets.
- a large diameter of the brake rollers according to claim 7 designed the inlet into the Fangnip advantageously flat.
- FIG. 1 shows the side view of a cross-cutting device
- Figure 2 is an enlarged detail of the brake and overlap device
- Figure 3 is an enlarged plan view of the braking device with the brake rollers
- Figure 4 is a cross section through a brake roller and its storage.
- the device shown in Figure 1 in an overall view is used to produce paper or cardboard sheets from a continuously fed web 1.
- web / sheet running direction in the figures from left to right, the following components are arranged one behind the other:
- a longitudinal cutting device 2 in which the edges of the web 1 is cut and optionally the web 1 is divided into up to six individual webs, a cross-cutting device 3, a sheet transport device 4, from which the sheets produced during cross cutting are taken and decelerated, forming a scale flow , and a stacking device 5, in which the sheets are stored on stacks 6, which lie on pallets 7.
- the cross-cutting device 3 contains in known manner two superimposed knife drums 8; each of which is equipped with at least one transverse knife, of which the web 1 is divided into sheets during the passage. Become several Lanes 1 processed superimposed, so arise when cross-cutting sheet packages, which are then transported on.
- the sheet transport device 4 is arranged, whose outlet-side part is shown enlarged in Figure 2. It includes elements for taking over the web start produced at a cross section and for tightening the web in cross cutting, for accelerated onward transport of the arc generated at a cross section to create a gap between two sheets, and a braking device 9 for braking a sheet for producing a scale flow from overlapping sheets, which is fed with slowed transport speed of the stacking device 5.
- the sheet transporting device 4 starts with a fast revolving upper belt conveyor 10 and an associated lower fast belt conveyor 11, which are composed of individual parallel belts and are driven at an increased speed relative to the speed of the incoming web 1.
- a sheet produced at the cross section is transported further at an increased speed.
- the brake and overlap device 9 begins with a suction box 13 which can be acted upon under negative pressure and whose upper wall provided with suction openings runs parallel with a certain distance below the conveying plane. From the negative pressure, the trailing edges of the sheets are sucked and deflected downwards. In this case, the trailing edges of the sheets of a high-speed upper belt conveyor 15, which extends over the length of the braking and overlapping device 9 solve.
- the suction box 13 begins a lower belt conveyor 14, which runs at the slower filing speed with which the sheets are placed on the stack 6. When braking an arc, the leading edge of a subsequent, even faster moving sheet slides over its trailing edge. This results in a scale flow of overlapping sheets, which is further promoted with the slower storage speed on the lower belt conveyor 14.
- Brake rollers 19 are arranged, which are each mounted freely rotatably, wherein the axes of rotation horizontally and transversely to the sheet running direction and substantially aligned with each other.
- the brake rollers 19 are arranged at an axial distance from each other between two upper belts 14 and extend circumferentially down beyond this. They thus form with the lower belt conveyor 14 a Fangnip, in which enter the sheets with their leading edges.
- the lower belt conveyor 14 is supported in the region of the brake rollers 19 by support rollers 17 so that the contact pressure required for braking can be applied to the sheets.
- a brake roller 19 with its suspension is shown enlarged in cross section in FIG. 4:
- Each brake roller 19 consists of a base body 20 in the form of a hollow cylinder, which is preferably made of light metal, for example made of aluminum.
- a layer of an elastically deformable material is applied to the base body 20 as a jacket, so that the largest possible contact surface is formed when the brake roller 19 is pressed against the sheets.
- the cladding layer is made of a cellular elastomer produced by foaming, in particular polyurethane.
- the brake rollers 19 have an outer diameter between 50 mm and 350 mm, preferably between 150 mm and 250 mm. Its measured width in the direction of its axis of rotation is 20 mm to 200 mm, preferably 20 mm to 100 mm. They are designed in width and arranged across the working width so that the sum of the roll widths is more than 25%, preferably more than 50% of the working width of the device, as shown in Figure 3. This ensures a sufficiently large contact surface with the bows.
- each brake roller 19 is resiliently mounted and movable by the force of an incoming sheet up, preferably each brake roller 19 individually.
- each brake roller 19 is mounted on two laterally mounted leaf springs 21, which are fastened with its other end to a crossbeam 22.
- the cross-beam 22 is pivotally mounted in the machine frame about its horizontal and transverse to the sheet running direction longitudinal axis, wherein the Angular position by means of a pivot drive, in the example of a handwheel 23, very finely adjusted and can be fixed.
- About the setting of the swivel angle can thus adjust the spring force of the bearings of the brake rollers 19 and thus the pressure force in Fangnip. This allows adaptation to different web materials, eg. B. Paper types whose sensitivities to markings differ.
- the stroke of the vertical movement of the brake rollers 19 can be adjustably limited, so that the maximum end of Fangnips can not be unduly large.
- each brake roller 19 can be lifted individually and brought into an inactive position, if in their area a longitudinal section in the web 1 runs.
- the braking device 9 applied to the sheets conveyor belts are slidably mounted.
- the brake rollers 19 are - as described above- manufactured in lightweight construction and have a specific gravity of less than 500 kg / m 3 , preferably less than 300 kg / m 3 , on. They have so advantageous a low inertia and can be pushed by the force of an incoming bow upwards.
- the effective circumferential speed of the brake rollers 19 decreases almost to the conveying speed of the lower, slower arc, which is transported lying on the lower belt conveyor 14.
- the deceleration takes place so slowly and without pressure peaks, so that marks in the area of the sheet leading edges are prevented.
