Definitions
- the present invention relates to a method for performing precise adjustment of the radial interval between two cylindrical tools used in a strip or material processing station sheet, especially a material such as paper, cardboard or plastic, for making blanks of plant boxes and labels, as well as a processing station for the implementation of the process.
- Strip or sheet material processing stations used to date in machines for making blanks of folding boxes, usually include a top tool cutting and a smooth cylindrical lower anvil mounted in bearings arranged in a cassette arranged in each of the frames side of the machine.
- each end of the upper tool and the lower anvil has a bearing crown whose diameter is equal to the original diameter of the training gears.
- the cassette supporting the upper tool and the lower anvil is made up of two bearing blocks, the upper one and the other lower, which can slide vertically in openings fitted in each of the side frames of the machine.
- the upper and lower sliding blocks are connected between them by an elastic coupling device tending to lift the upper sliding block with respect to the lower sliding block so as to allow a limited stroke of the upper sliding block relative to the lower sliding block.
- the invention aims to eliminate the aforementioned drawbacks by proposing an adjustment method the interval between two cylindrical tools and a station processing which improve cutting operations while increasing the service life of tools.
- the advantage obtained thanks to the invention makes it possible to improve the cutting operations and increasing the service life of the tool superior by acting at the same time on the respective positioning of the tool higher compared to the lower anvil and on the control of conditions of the heat exchanges in the length of the tool and of anvil.
- Figure 1 is a schematic side view of a station rotary cutting 1 used in a machine intended for making of folding box blanks.
- stations can be placed one after the other in this kind of machines to realize each an operation such as for example press-up, embossing and cutting the strip or sheet of material to be shaped. It is enough to that of mounting, in each of the respective stations the rotary tools correspondents.
- the rotary tool upper cylindrical 2 is mounted in a first half-shell 3, 3a while the lower cylindrical rotary tool, the lower anvil 4, is to him mounted in a second half shell 5, 5a.
- These two half shells 3, 3a and 5, 5a are interconnected so as to form a cassette 6 housed in the frame 7 of the rotary cutting station 1.

- the half shells 3, 3a and 5, 5a are held against one another by tie rods 8, 8a and 9, 9a.
- Each of these tie rods 8, 8a and 9, 9a has a drawbar 17, 17a whose lower end has a thread 18, 18a engaging in a internal thread 19, 19a machined in the upper part of the half-shell lower 5, 5a.
- the drawbar 17, 17a crosses the lower part of the upper half-shell 3, 3a passing through a bore 20, 20a.
- the upper end of the drawbar 17, 17a has for its part a thread 21, 21a and a clamping square 22, 22a intended to receive a open end wrench.
- the thread 21, 21a is intended to receive a nut 23, 23a which will come to bear, during tightening, against the upper face of a spacer 24, 24a, the underside of this spacer 24, 24a will rest meanwhile against the face of the tab 25, 25a of the half-shell upper 3, 3a.
- FIG. 3 is a sectional view along III-III of FIG. 1, in which the bearings of the upper tool 2 and of the lower anvil 4.
- One end of the upper tool 2 has a cylindrical seat 26 on which are mounted two bearings with taper roller 27 and 28. These taper roller bearings 27 and 28 are secured in position on the cylindrical seat 26 by means of the spacers 29 and 30 as well as by a washer 31 fixed at the end of the shaft by screws 32.
- the tapered roller bearings 27 and 28 are housed in a bearing 33 fixed in the upper half-shell 3, using the screws 34.
- the sealing of the bearing 33 is obtained by the covers 35 and 36.
- the other end of the upper tool 2 has two cylindrical surfaces 37 and 38.
- the cylindrical seat 37 supports two tapered roller bearings 39 and 40 held laterally by spacers 41 and 42 and by a nut stop 43 acting on a circular ring 44 to tighten the rings inside of tapered roller bearings 39 and 40 against the shoulder 45 of the cylindrical seat 37.
- the tightness of the assembly is obtained using the cover 49 and the casing 50.
- a toothed wheel 46 is mounted on the cylindrical seat 38 on which it is fixed by means a double cone ring 47 tightened with screws 48.
- the toothed wheel 46 meshes with a drive pinion 51 and with a second wheel backlash toothed 52 which is keyed on the bearing 53 of the end of the lower anvil 4. This second toothed wheel 52 is held in its lateral position by a stop washer 54 fixed in shaft end by screws 55.
- Two tapered roller bearings 56 and 62 are mounted on the bearing surface 57 of the end of the lower anvil 4 and the sealing of the bearing thus formed is obtained by the cover 58 and by the casing 50.
- the other end of the lower anvil 4 has a bearing 59 fitted with two tapered roller bearings 60 and 61 insured laterally by spacers 63 and 64 and by a locking washer 65 fixed at the end of the shaft using screws 66.
- the outer rings of the tapered roller bearings 60 and 61 engage in the bore inside of a bearing 67 fixed to the lower half-shell 5 by screws 68. This assembly is sealed by the cover 69 and by the bell 70.
- FIG 4 is a sectional view along IV-IV of Figure 1 which represents one of the adjustable shims 10, respectively 11.
- the shim adjustable 10 is in the form of a screw whose cylindrical head 71 has holes 72 in which a rod can be engaged for activate it in rotation when adjusting.
- the cylindrical head 71 of the screw has a shoulder 73 intended to come into contact with the part lower of the upper half-shell 3 and a micrometric thread 74 engaging in a thread fitted in the upper part of the lower half shell 5.
- Figure 5 is a schematic view showing the distribution temperatures in a conventional cutting station.
- the temperature of the ends of cylinders 2 and 4 causes a variation dimensional of these which is more important than the variation the central zone of these cylinders 2 and 4.
- the distribution of temperatures is represented by diagram 84 attached to the presents figure in which the distance between the bearings is carried in abscissa while the temperature is plotted on the ordinate, the curve resulting which can be compared to the curve representing the shape of the dimensional variation of upper tool 2 and lower anvil 4.
- This deformation of the upper tool 2 and the lower anvil 4 causes an imperfect cut of the material which passes between them. Indeed, the cut located in the area near the ends of the tool or the anvil will always be better than the cut located in their area median. Such a result is unacceptable in practice.
- FIG 6 is a schematic view showing the distribution temperatures in a cutting station according to the invention.
- the bearings 80, 81, 82 and 83 shown in this figure have been fitted with a thermal conditioning device (see Figure 7).
- Each level 80 to 83 includes an oil inlet 86 and an oil outlet 87 intended for condition them individually while ensuring at the same time the necessary lubrication functions. So by cooling the bearings this way, we will get a temperature distribution curve 85 which will take the form of the one attached to this figure.
- FIG. 7 represents a functional diagram of a device for thermal conditioning 92 used for cooling the bearings 80 to 83.
- the thermal conditioning device 92 can be obtained freely from commerce and comes from the company FURRER AG, CH-8108 D ⁇ LLIKON which issues it under the reference OK 25. It includes among others four air conditioning elements 88 to 91 each delivering the oil conditioned by the pipelines 86 at each of the bearings 80 to 83 and receiving the circulation and lubrication oil from the bearings 80 to 83 through pipes 87.
- each bearing 80 to 83 is equipped with a temperature 93 electrically connected by a cable 94 to each of the air conditioning elements 88 to 91.
- a room sensor 95 is arranged in the vicinity of the upper tool 2 and the anvil 4. This room sensor 95 is also electrically connected by cable 96 to each air conditioning element 88 to 91.
- the device for thermal conditioning 92 will be able to calculate exactly the temperature at which it must deliver the oil to each of the stages 80 to 83, this according to the actual temperature conditions existing in the cutting station in order to produce dimensional changes compensating for those caused by the temperature rises in the tool length.
