Definitions
- the invention relates to a machine for cross-cutting webs of material, in particular paper or cardboard webs, with a machine frame consisting of a side wall on each long side of the machine, the side walls being connected to one another via crossbeams, and with two knife drums with their axial Ends are each stored in the side walls.
- Machines for cross-cutting paper or cardboard webs are known to contain two knife drums rotatably mounted one above the other in a machine frame, the knives of which cut a material web passing between them with a scissor cut.
- the machine frame consists of side walls that are connected to each other by cross beams.
- the machine frame is made in a welded steel structure.
- the trusses are welded to the side walls.
- the side walls consist of several side parts that are screwed or welded together.
- a generic cross cutting machine of this type is described in DE 198 03 522-A.
- the invention has for its object to improve a generic cross cutting machine so that it is able with a structurally simplified design to cut material webs with high cutting accuracy at a very high production speed.
- this object is achieved in that the side walls of the machine frame are constructed from side parts, the corresponding side parts being cast from one piece on both longitudinal sides with at least one connecting crossbar.
- This construction enables a very high level of manufacturing accuracy and ensures extremely high rigidity of the frame, since there are no screw connections that impair stability. Furthermore, the machine frame can be assembled in a simplified manner since it is constructed from fewer parts.
- the machine frame is made up of two frame parts, each frame part consisting of two side parts connected to one another by at least one crossbar.
- the dividing line between two side parts on each long side runs through the two axes of rotation of the cutterhead.
- the machine frame consists of a main frame, which has a horizontal step underneath the bearing of the knife flow, and an additional frame placed on this step.
- the side parts have cast-on bearing shells for receiving the rolling bearings, in which the knife drives are mounted. Since no screwed-on bearing flange is required, the bearing openings can be arranged at a smaller distance from one another. This makes it possible to use larger roller bearings in diameter and thus to provide the knife drums with thicker shaft journals.
- the pulling device for the web consisting of two clamping rollers for the web in the web running direction is mounted in front of the knife drums in the machine frame.
- the pulling device therefore does not require its own frame.
- all of the wider machine elements, in particular the gear wheels of the knife drums and the lifting drive for a feed roller, are arranged on the outside of the side walls. This makes it possible to make the machine frame as narrow as possible with a clear width between the side walls that is a maximum of 200 mm wider than the maximum web width of the incoming material web.
- This configuration has the further advantage that the additional machine elements are easily accessible for maintenance work.
- FIG. 1 shows a view in the web running direction of the cross cutting machine
- Figure 2 is a side view
- Figure 3 is a side view of the machine frame made up of a main frame and an additional frame.
- the cross-cutting machine shown schematically in sections in FIGS. 1 and 2 is used for cross-cutting paper or cardboard webs in the production of paper or cardboard sheets. It works at web speeds of several 100 m / min, for example at 400 m / min, and cuts sheets in format lengths from approx. 400 mm to approx. 200 mm. Their working width, ie the maximum width of the web to be processed, is in the range of one to several meters, in the exemplary embodiment 2200 mm.
- the desired format widths are set by longitudinally cutting the web by means of a longitudinal cutting device, not shown, from which the web is divided into individual webs of the desired width before cross-cutting.
- the cross cutting machine contains two knife drums 1, 2, which are rotatably mounted at their axial ends in side walls 3, 4 of the machine frame.
- the two knife drums 1, 2 are arranged one above the other with parallel axes of rotation.
- Each knife drum 1, 2 is equipped on its circumference with a knife 7, 8, which are fastened in a known manner helically in the axial direction over the working width. They are set against one another in such a way that they cut through a continuous web with a scissor cut, the helical arrangement of the knives 6, 7 making it possible to cut through a continuous web perpendicular to the web running direction.
- Each knife drum 1, 2 consists of a cylindrical base body, on the end faces of which shaft journals 8, 9 are attached.
- the shaft journals 8, 9 are rotatably supported in the side walls 3, 4 via roller bearings 10.
- a gear wheel 11, 12 is attached to each shaft journal 8, 9 as a synchronization spur gear, the gear wheels 12 of the upper cutter drum 2 engaging in the gear wheels 11 of the lower cutter drum 1.
- the gears 11, 12 are each arranged on the outside of the side walls 3, 4.
- An electric motor as a rotary drive for the knife drums 1, 2 is coupled at least to a shaft journal 8, 9, which is flange-mounted on the outside on a side wall 3, 4 of the machine frame.
- there are two drive motors 13, 14 which are each coupled to a knife drum 1, 2 in a so-called Z arrangement on both machine sides.
- the machine frame, built on a foundation 15, consists of the two side walls 3, 4 and cross members 16, 17, 18, 19, which connect the side walls 3, 4 to one another.
- each side wall 3, 4 consists of two side parts 21, 22 which can be screwed together by means of screws 23. It is essential for the invention that the side walls 3, 4 are constructed from side parts 21, 22, the corresponding side parts 21 and 22 being cast in one piece on both longitudinal sides with at least one, preferably all, connecting cross-members 16, 20.
- the machine frame contains a main frame, which is formed by the two side parts 21 and the connecting cross members 16, 17, 18, 19 molded from the piece with the side parts 21.
- a further side part 22 forms an additional frame with the connecting cross member 20, which is also cast from the piece with the side parts 22, and which can be screwed onto the main frame.
- Each side wall 3, 4 is divided such that the dividing line runs partly in a straight line between two side parts 21, 22 through the axes of rotation of the two knife drums 1, 2.
- Each side part 21 of the main frame has a horizontal step below the bearing of the knife drums 1, 2. The respective side part 22 of the additional frame is placed on this step.
- each side part 21, 22 has two semicircular cutouts 24, 25 arranged at a short distance above one another on the vertical edge on which the side parts are screwed together.
- the two recesses 24, 25 each form a circular bearing opening into which the bearing 10 of a knife drum 1, 2 is inserted.
- a bearing shell 26, 27 is cast on the outside around the bearing opening, so that no additional bearing flange is required.
- Two further semicircular bearing shells 28, which are also cast on the respective side part 21, 22, form a fastening flange for a drive motor 14.
- the two-part shape of the machine frame makes it possible to open the storage of the knife drums by unscrewing the additional frame and thus quickly installing and removing a knife drum 1, 2.
- a web pulling device which consists of two clamping rollers 29, 30, is arranged directly in front of the knife drums 1, 2.
- the lower pinch roller 29 is driven via a belt drive by a drive motor 31 which is attached to the side wall 3. It is supported at each axial end in a bearing opening 31 in a side part 21.
- the upper feed roller 30 is freely rotatable and can be lifted off the lower feed roller 29 so that a web can be introduced between the two rollers 29, 30.
- the fact that the upper feed roller 30 can be lifted off is made possible by the fact that it is supported with its lateral ends in ring-shaped bearing bushes which are fastened eccentrically rotatably on the inside of the respective side part 21.
- the eccentrically mounted bearing bushes are connected via levers to a pneumatic piston-cylinder unit, which acts as a lifting drive for the upper feed roller 30.
- the pneumatic piston-cylinder unit and the levers acting on the bearing bush are on the outside of everyone Side wall 3, 4 stored.
- the opening 32 is indicated in the side part 21, via which a lever is connected to the inner bearing bush.
- the clear width between the two side walls 3, 4 is kept as small as possible. Therefore, all machine elements with the exception of the knife drums, which have a width of more than 100 mm, are arranged on the outside of the side walls 3, 4. Such machine elements arranged on the outside are the gearwheels 11, 12, the lifting drive for the upper feed roller 30 and the drive for a web clamping device. As far as the machine elements for functional reasons in the area between the maximum working width and the
