Definitions
- the proposed device relates to the displacement of lower knives for cutting webs of paper, foil, fabric, plastic, metals or the like in one running direction, these lower knives being mounted on a shaft supporting them and means for holding the particular, in particular sleeve-like, manner Lower knife are provided in a desired position.
- a device of this type can be seen, for example, from DE-AS 18 02 305.
- the so-called lower knives are each driven by their own motor and, with the help of an air cushion, are moved to the desired position across the width of the web to be cut, on a guide arranged transversely to the running direction of the web.
- the device of DE-AS 18 02 305 it is possible with the help of the device of DE-AS 18 02 305 to move the lower knives in a smooth manner to the position desired for a particular cutting process.
- DE-AS 18 02 305 shows that the web to be cut into individual strips runs essentially tangentially between the respective lower knife and the respective upper knife, that is to say is used to produce a so-called tangential or straight cutting process.
- DE-AS 10 38 902 shows that pneumatically expandable means have already been used to fasten tubular bodies to shafts in order to fasten the tubular bodies or lower knives to the shafts carrying them.
- it is disadvantageous to embed expandable members in the load-bearing shafts since this would also weaken the cross-section of the load-bearing shafts and the shaft could bend easily even with low forces. For this reason, it is proposed in DE-AS 10 38 902 to position the expandable members outside the supporting shaft.
- the present invention consciously turns away from this train of thought in order to be able to fulfill the task of cutting sleeves in question standing type in order to be able to move a division of the cut into it in a smooth manner.
- At least one first groove is incorporated into the shaft carrying the sleeve-shaped lower knives, such as knife sleeves, in each of the first grooves, a fitting piece which can be displaced in the axial direction of the shaft together with the respective cutting sleeve, between the radially inside lying surface of the respective fitting piece and the bottom of the respective first groove in a flat cage inserted needles, rollers or the like.
- the needles, rollers or the like Both the radially inner surface of the respective fitting piece and the bottom of the respective touching flat groove and the cages in the axial direction-of the shaft by at least one groove pitch of the cutting sleeve member are shorter than the respective fit s - pieces.
- At least one second groove or a plurality of second grooves can be incorporated into the shaft carrying the cutting sleeves, the first groove (s) relative to the second groove ( en) can be arranged offset to one another in the circumferential direction of the shaft and an expandable chamber, hose or the like can be inserted into each of the second grooves, which expands the respective cutting sleeve radially from the inside and can be filled with a pressure medium.
- At least one upper knife 1 and one lower knife 2 are rotatably mounted in a machine frame 3.
- This machine frame can for example consist of two mutually parallel side walls, between which the upper knife 1 and the lower knife 2 are rotatably mounted on these supporting shafts.
- a plurality of knives can also be arranged one behind the other in the viewing direction of FIG. 1, so that a web to be cut can be cut into at least two or even more strips in the direction of travel.
- the web 4 for example coming from a rolling device, can be cut into a plurality of strips 5 with the help of the knives 1 and 2, these strips being arranged one behind the other in the direction of view of the viewer of FIG. 1 and running out of the cutting device in the direction of the arrow 6 to be fed to a winding device, for example.
- the dashed path of the web 4 and the strips 5 cut therefrom is essentially horizontal, ie "straight", whereas the path 7 shown in solid lines and the strips 8 cut therefrom the bottom knife 2, as by indicated the angle 9, at least partially looping around it, that is to say representing a so-called looped section.
- the strips 8 lying one behind the other in the viewing direction of the viewer leave the cutting device, for example in the direction of the arrow 10.
- FIG. 3 shows a tubular shaft 11, which contains a supply channel 12 for a pressure medium in its interior.
- This feed channel can have a much smaller diameter than shown in FIG. 3.
- bush-shaped lower knives so-called cutting bushes 13, 14 and 15, are mounted such that they are supported and held by the shaft 11.
- the cutting sleeves form the lower knife 2 of FIG. 1.
- several or only one or two cutting sleeves can also be arranged on the shaft 11.
- first grooves 16, 17 and 18 are incorporated into the shaft 11. These first grooves maintain a pitch angle 19, 20 and 21 of 120 °, for example.
- Fig. 2 shows that second grooves 22, 23 and 24 are also machined into the shaft 11 and also maintain a pitch angle 25, 26 and 27 of, for example, 120 ° with each other and that the two types of pitch angles with each other by an angle 28 of, for example, 60 ° are arranged offset from one another in the circumferential direction.
- the exemplary embodiment shows three first and three second grooves. However, it is not absolutely necessary to maintain such a trinity, for example only one type of groove is possible in each case or two or four or more grooves per type of groove, so that the pitch angle changes accordingly.
- each of the first grooves for example in the groove 16, a fitting piece 29 is inserted. It is fixed with the aid of screw connections 30 and 31, for example, to the cutting sleeve 14 in such a way that it is displaced when the cutting sleeve 14 is displaced with respect to the shaft 11, ie when the cutting sleeve 14 is displaced in the axial direction of the shaft 11.
- rollers or the like 34 are inserted between the radially inner surface 32 of the fitting 29 and the base 33 of the first groove 16, which needles are kept at a certain distance from one another with the aid of a flat cage 35. Rollers or the like. 34 touch both the bottom 33 of the first groove 16 and the radially inner surface 32 of the fitting 29.
- the radially inner surface 36 or at least a part of this surface of the cutting sleeve 14 and the radially outer surface 37 of the fitting 29 can be held slightly obliquely in a wedge-like manner, so that an exact adjustability between the base 33 of the first groove 16 , the needles, rollers 34, the fitting 29 and the cutting sleeve 14.
- the threaded bores of the screw connections 30 and 31 are formed, for example, as so-called fitting bores, which are drilled when the device is assembled. The thread is then cut into these holes when the respective cutting sleeve is assembled.
- the cages 35 are, for example, by the dimensions 38 and 39 shorter than the axial extent 40 of the fitting 29 or the cutting sleeve 14.
- This difference in the axial dimensions can, for example, be as large as one Pitch 41, which two cutting edges of the cutting sleeve 14 adhere to one another.
- the cutting sleeve 14 can be moved in the axial direction along the shaft 11 without the cage 35 being able to emerge from the cutting sleeve 14 when viewed in the axial direction, provided that this axial movement is the measure of the pitch 41 does not exceed.
- the sum of the dimensions 38 and 39 equals, for example, the distance which three cutting edges of the knife sleeve keep from one another.
- T-shaped pressure pieces 42 are inserted in their cross section, which reach through openings 43 of the shaft 11 and bear radially from the inside against the respective cutting sleeve.
- At least one hose 44 is also let into each of the second grooves, the inside of which is connected to the feed channel 12 of the shaft 11 by means of at least one bore 45 each.
- pressure medium for example compressed air
- pressure medium can be introduced into the feed channel 12 in order to thereby expand the hoses 44, to move the pressure pieces 42 radially outward and in this way to hold the respective cutting sleeve at a desired position after the adjustment process.
- each end face of each cutting sleeve with claws 47, toothing or similar devices which are designed in such a way that the adjacent cutting sleeves can move against one another even if the claws of the adjacent cutting sleeves interlock. This would ensure that the web would not sag, but would also be supported at those points where there are gaps between the cutting sleeves. At the same time, any markings in the web to be cut or on the cut strips are prevented.
