Definitions
- Device for cross cutting material webs in particular paper or cardboard webs
- the invention relates to a device for cross cutting material webs, in particular paper or cardboard webs, with a cross cutting device containing two knife drums equipped with transverse knives and with a sheet transport device arranged behind the cross cutting device and containing a braking device with a brake roller.
- Cross-cutting devices which produce individual sheets from a paper or cardboard web by cross-cutting and which are subsequently deposited on a stack, contain, as is known, behind the cross-cutting device
- Sheet transport device which is a braking device with a brake roller.
- a braking device with a brake roller.
- the leading edge of the still unbraked following sheet pushes over its rear edge. In this way, a shingled stream of overlapping sheets is generated, which is then placed on a stack in a stacking device.
- a generic cross cutting device is described in DE 199 45 114.
- the invention is therefore based on the object of improving a generic cross-cutting device in such a way that markings on the sheets are avoided even with sensitive types of paper or cardboard.
- the brake roller consists of a cylindrical base body, on which fins made of an elastic material which protrude radially from one another are fastened and which end in a cylindrical envelope surface which is coaxial with the base body.
- the design of the brake roller with radially projecting plates means that the arc is braked by largely releasing its kinetic energy to a plate.
- the elastic slats spring back and give way, whereby the spring travel is the braking distance of the bow.
- the effective circumferential speed of the brake roller adjusts itself almost to the conveying speed of the slower sheet due to the sheet pressing against a plate. It is only after the faster sheet has been largely braked that it is pressed onto the leading sheet.
- FIG. 1 shows the side view of a cross cutting device
- Figure 3 shows a cross section through the brake roller. Ways of Carrying Out the Invention
- the device shown in an overall view in FIG. 1 is used to produce sheets of paper or cardboard from a continuously fed web 1.
- the following components are arranged one behind the other in the web / sheet running direction (from left to right in the figures):
- a slitter 2 in which the edges of the web 1 are trimmed and, if necessary, the web 1 is divided into up to six individual webs, a cross-cutting device 3, a sheet transport direction 4, of which the
- Cross-cut sheets are taken over and braked, forming a shingled stream, and a stacking device 5, in which the sheets are placed on stack 6, which lie on pallets 7.
- the cross cutting device 3 contains, in a known manner, two knife drums 8, 9 arranged one above the other, which are equipped with at least one transverse knife, of which the web 1 is divided into sheets as it passes.
- the sheet transport device 4 which is shown enlarged in FIG. 2. It contains elements for taking over the beginning of the web created in a cross-section and for tightening the web during cross-cutting, for accelerating the further transport of the sheet created for a cross-section in order to create a gap between two sheets, and for braking a sheet to produce a shingled stream from overlapping sheets , which is fed to the stacking device 5 at a slower transport speed.
- the sheet transport device 4 begins with an upper catch roller 12 and an associated lower fast belt conveyor 13.
- the catch roller 12 is at the same time the entry-side deflection roller of a fast rotating upper belt conveyor 14, which is constructed from individual parallel belts and with a speed that is equal to the speed of the incoming web 1 increased speed is driven.
- the lower belt conveyor 13 forms with the catch roller 12 a nip from which an incoming web start is taken over.
- the belt conveyor 13 is driven at the increased speed of the upper belt conveyor 14. This is how a Cross section produced sheet transported at an increased speed.
- the braking and overlapping device begins with a suction box 16 which can be subjected to negative pressure and whose upper wall, provided with suction openings, runs parallel and somewhat at a distance below the conveying plane.
- the trailing edge of the sheets is sucked in by the negative pressure and deflected downward.
- a lower belt conveyor 17 which runs at the slower deposition speed at which the sheets are deposited on the stack 6.
- Each brake roller 20 consists of a cylindrical base body 20 which is mounted on the common rotatable axis 21.
- radially projecting lamellae 22 made of an elastic material are fixed at a circumferential distance from one another and end in a cylindrical envelope surface coaxial with the base body 20.
- the lamellae 22 are preferably produced in such a way that slots which extend axially over the circumference are cut into a hollow cylinder made of elastic material.
- the hollow cylinder has an outer diameter of approximately 220 mm, and slots of approximately 20 mm depth are cut.
- the slats 22 are preferably inclined somewhat counter to the running direction 23 of the arches 24, as can be seen from FIG. In the exemplary embodiment, the angle of inclination is approximately 20 ° to the radial.
- the lamellae 22 are undercut at their ends, so that their end surface lies essentially in a common cylindrical envelope surface.
- the fins 22 are made of an elastic and highly wear-resistant material. They are preferably made from a cellular plastic material with a large number of pores, which is not only elastic but also to a certain extent volume-compressible. They are preferably made from a cellular elastomer produced by foaming, in particular polyurethane.
- a plurality of brake rollers 19 of the same structure are arranged at a distance from one another on the rotatable axis 21, the disks 22 of which end in a common cylindrical envelope surface, that is to say have the same radial position.
- the design of the brake rollers 19 has the effect that a sheet 24 coming in with its leading edge of the sheet is braked by its kinetic energy being released to the plates 22.
- the elastic slats 22 are pressed backwards and yield resiliently.
- the spring travel corresponds to the braking distance of an arc 24. If a volume-compressible material is used for the plates 22, part of the braking energy is also converted into deformation energy.
- the effective peripheral speed of the brake roller 19 is reduced when braking a sheet 24 to almost the conveying speed of the lower, slower sheet 24, which is transported lying on the lower belt conveyor 17. The braking takes place so slowly that striking and thus markings on the leading edge of the sheet are prevented.
- the undercut of the slats 22 at their end causes a subsequent sheet 24 to be pressed as late as possible onto the slower sheet 24 underneath.
- the slats 22 press an arc 24 only slightly downward, since the slats 22 can buckle and thus dodge.
- only the possibly remaining relative speed is braked when the subsequent sheet 24 is pressed onto the leading sheet 24.
- the pressure is also applied with only a small contact pressure, so that markings on the sheet surfaces are avoided. Since the brake roller 19 rotates, the disks 22 spring back after they have lifted off the arch 24.
