Definitions
- the invention relates to a longitudinal cutting machine for cutting a material web guided through the longitudinal cutting machine with a cutting arrangement having at least one upper knife for the material web guided by the cutting arrangement over the cutting point formed by the upper knife.
- a longitudinal cutting machine with the aforementioned generic features is known from US 3 185 010.
- Such longitudinal cutting machines have applications in which the material to be cut, depending on the ambient temperature, more or less impairs the cutting process. For example, when cutting material webs coated with an adhesive material, frequent material remnants stick to the knives, and the temperature rising at the cutting point due to the cutting friction can also impair the cutting result, which is particularly true for the high cutting speeds sought.
- the invention is therefore based on the object of providing a longitudinal cutting machine with the generic features which enables a better cutting result with temperature-sensitive materials, even at high cutting speeds.
- the basic idea of the invention provides that the knife blade of the upper knife can be acted upon with at least one nozzle aligned with the upper knife with a cooling medium such that the temperature of the knife blade does not exceed a predetermined temperature during the cutting operation of the longitudinal cutting machine.
- the invention is aimed at cooling the knife blade of the upper knife in a longitudinal cutting machine by applying a suitable cooling material or to keep the temperature of the knife blade below a set temperature even during the cutting process, so that even at very high temperatures
- a plurality of nozzles which are arranged distributed over the circumference of the circular knife blade and are directed towards the knife blade are provided; alternatively, it can also be provided that a nozzle, which extends over the circumference of the circular knife blade and is designed in the manner of an annular gap, is provided.
- the knife is designed as a long knife and a plurality of nozzles arranged at a distance from one another over the length of the knife edge of the long knife is provided ; alternatively, it can also be provided that the knife is designed as a long knife and that a slot-shaped nozzle extending over the length of the knife edge is provided.
- the nozzle for the cooling medium to be passed through is aligned with the inner side of the knife blade which rests against the lower knife in the case of a scissor cut; since, in this cutting area in particular, the occurrence of buildup of the material web is most likely, the invention starts here by cooling the inside of the knife blade.
- the knife blade of the upper knife can be acted upon by the cooling medium from nozzles arranged on both sides.
- it can be provided to cool the knife edge in particular, and for this purpose, according to one embodiment of the invention, it is provided that at least one nozzle is aligned with the knife edge in a radial arrangement with respect to the knife blade.
- a nozzle arrangement is set up to act on a plurality of knife blades when the knife blades are arranged at a short distance from one another. Such an arrangement is particularly suitable for very narrow cutting widths.
- a constant flow of cooling medium can be passed through the nozzles or the cooling medium is applied to the nozzles at time intervals.
- the upper knife including the nozzle aligned on its knife blade, is enclosed by a housing, it being possible for a suction device for the applied cooling medium to be connected to the housing.
- the housing with an associated nozzle arrangement can accordingly include a plurality of knife blades.
- a temperature sensor for detecting the respective temperature of the upper knife is assigned to the knife blade.
- At least one nozzle is aligned with the area of the material web which has already been cut and which lies behind the cutting point and surrounds the cutting edge in the material web.
- the lower knife assigned to the upper knife is designed as a lower knife shaft with cutting edges arranged thereon and the lower knife shaft is set up to pass the cooling medium through.
- the invention is also suitable for cutting arrangements operating in a squeeze cut, and if the upper knife works against a shaft, the shaft can also be set up for cooling the upper knife by passing the coolant through it.
- cooled air, an inert cooling gas, a liquid nitrogen or a liquid carbon dioxide can be supplied as the cooling medium; other suitable media can be used in the context of the invention.
- Fig. 1 shows a cutting arrangement consisting of one on one
- Knife holder held, upper knife designed as a circular knife, and from an associated lower knife with cooling nozzle,
- FIG. 2 shows the cutting arrangement according to FIG. 1 with a plurality of
- FIG. 3 shows a cutting arrangement in another embodiment with upper knives arranged on a knife shaft, including assigned cooling nozzles,
- FIG. 4 shows the cutting arrangement according to FIG. 1 with an additional cooling area for the material web arranged before it passes through the cutting arrangement
- 5 shows the cutting arrangement according to FIG. 1 with an additional cooling area for the material web arranged behind the passage through the cutting arrangement
- Cooling nozzles Cooling nozzles.
- FIG. 7 shows a further exemplary embodiment of the cutting arrangement according to FIG. 1 with a radially arranged nozzle and a housing with a suction device
- an upper knife designed as a circular knife 12 is held on a knife holder 10 by means of a lowering device 11 and is enclosed by a hand guard 13.
- a lower knife 15 is assigned to the knife blade 14 of the circular knife 12 in such a way that a cutting point 16 results through which a material web 17 is guided in the transport direction indicated by the arrow 18.
- a nozzle 19 is aligned with the knife blade 14 in order to cool the knife blade 14 by passing a suitable cooling medium through the nozzle 19 before the assigned knife edge respectively the cutting point
- corresponding nozzles can be formed on both sides of the blade 14 for the passage of the cooling medium, so that, as indicated by the arrows 30, a corresponding cooling medium is directed onto the blade 14 on both sides can.
- a plurality of nozzles 19 can be arranged distributed over the circumference of the knife blade 14.
- a circumferential annular gap nozzle 20 is arranged so that the entire circumference of the blade 14 can be flowed through the annular gap nozzle 20 with the cooling medium.
- FIG. 3 a further embodiment of the invention is shown, in which a plurality of circular knives 12 are arranged as upper knives on a common knife shaft 23, which work in a scissor cut against lower knives 15 with correspondingly assigned knife edges, each of the circular knives 12 each in their respective A nozzle 19 is assigned to the cutting point 16 opposite region.
- the material web 17 is additionally cooled in the transport direction 18 of the material web 17 before the cutting point 16 by a cooling bar 21 with a plurality of cooling nozzles 22 arranged therein arranged parallel to the surface of the material web 17 is.
- the material web 17 is cooled.
- a cooling beam 21 with correspondingly assigned cooling nozzles 22 extends behind the cutting point 16 in a direction parallel to the material web 17 in the transport direction 18 of the material web 17.
- the region of the material web 17 which already includes the cut edge already cut in the material web 17 is thus cooled, and in this way it is achieved in a particularly advantageous manner that with the cooling of the material web behind the Cutting point 16 a certain embrittlement of the material web 17 occurs, so that after a possible standstill of the slitting machine when the material web starts up again, the cut parts of the material web automatically separate from one another.
