Definitions

  • the invention relates to a device for achieving tightly wound bundles of the same diameter when winding up a plurality of narrow strips, which are obtained by slitting a strip produced by hot or cold rolling and, after being wound onto a common mandrel of a reel, fed as a narrow strip bundle for further processing, consisting of a Strip insertion device with a boom that can be swiveled perpendicularly to the reel mandrel, which has a cassette part for receiving elongated strips of cardboard or the like, a device for conveying the strips from the cassette part in the direction of insertion, and a free-running feeler roller with an upstream drive roller set to forward the strips includes under the feeler roller.
  • a rolled metal strip generally shows changes in thickness in the transverse direction, which are due to inaccuracies in the rolling.
  • the metal band is usually slightly thicker or thinner in the middle than on the sides and there are different internal tensions in the band between the band sides and the band center.
  • Different sliver thicknesses in slitting lines cause different coil diameters when winding.
  • braking systems e.g. DE-OS 1552598
  • these braking systems can often no longer be installed in existing systems.
  • the applicant has the solution to the task of being able to achieve straight and tightly wound bundles of the same diameter without unnecessarily stressing the surfaces of the narrow-band slit strips by using external aids in the form of restraint devices such as band brakes or band tensioning rollers and without endangering an operator the technology already enriched by the teaching to provide an automatically operating strip insertion device with a cassette for receiving strips which are slightly smaller in width than the smallest narrow-band gap width occurring in the respective cutting program.
  • the strip insertion device can be moved in the transverse direction on a guide and can be directed from a remote control panel, in such a way that the strip insertion device is brought into exact position in front of any desired narrow-band collar by constant transverse movement and by placing strips under it Paper, cardboard, plastic or metal are - between individual layers of the bundles being built up compensating for the diameter deviations caused by the differences in strip thickness when winding up slit strips (cf. DE-U 7718103).
  • the device described above is equipped with a single cassette and is designed in such a way that the cassette only accepts those strips which correspond in width to approximately the smallest narrow-band gap width occurring in the cutting and thus reel program, problems are associated with it.
  • a cutting program which has considerable differences in the width of the individual narrow-band gap widths, the desired tight and straight bundles can be achieved. It is true that flawless bundles are still achieved on the narrowest slit strips and the slit strips differing only insignificantly in their width, since - as explained above - the cassette is only occupied with the paper strips required for the smallest dimensions of the slit strips.
  • the invention is therefore based on the object of providing a strip insertion device which, even in any cutting program with very different narrow-band split strips, enables the reeling of fixed and straight-line narrow-band split strips, and on the other hand nevertheless ensures that the system is in the operating area before the reel-up Execution there not agile work such as threading the beginning of the tape, gluing the finished bundles etc. is easily accessible.
  • the strip inserting device is operated by pushing an operator from a remote control panel, which causes the selective insertion of a paper strip into the winding slot of the sagging slit in each case, namely soft paper strips are sent between the individual winding layers of a narrow-band slit bundle until the incoming one Split band is tight.
  • Several insertion processes can be selected at the same time without difficulty, i.e. there is a simultaneous insertion of paper strips on different narrow-band slit coils.
  • a compilation of individual cassettes for another cutting program can be prepared by means of setup aids during operation if, according to a further invention proposal, an exchangeable main cassette which is detachably connected to the extension arm is provided for receiving the individual cassettes.
  • the magnets can be accommodated in any case on the displaceable swivel arms for moving the insertion arms, and then only those insertion arms remove strips from the individual cassettes, the associated lifting magnets of which are actuated and establish a rotationally fixed connection between the common axis and a swivel arm, with which the longitudinally movable displacement movement is also transmitted to the insertion arms.
  • the strip inserting device mounted in front of the reel with the wide main cassette constricts this operating area of the installation to a considerable extent, so that the work which is necessarily to be carried out in this zone can hardly be carried out entirely without hindrance.
  • the invention according to claims 11 to 14 provides that the area in front of the reel can also be cleared by a strip insertion device which can be moved parallel to the reel mandrel.
  • the pivotable boom is expediently designed to be telescopically retractable and extendable.
  • Claim 16 specifies a development of the subject of the invention for the condition that the running-in ratios of the slit strips - which are determined by the constantly changing ratio of the point of departure of the strips on the deflection roller to the point of contact of the strips on the reel when the diameter on the reel is so favorable - that the shield-like supporting part cam tracks according to DE-U 7718 103, which otherwise make an adjustment of the adjustment movement of the cantilever with the cassette to changing run-up angles, can be omitted.
  • the boom of the strip inserting device which in this case is fixed overall in front of the reel, is either pivoted upwards or downwards in the telescopic position of the boom, thus clearing the space in front of the system for operating personnel.
  • Fig. 1 shows an embodiment with a transversely movable strip insertion device 6 with boom 6a.
  • the stationary substructure 1 has two pairs of bearing blocks 2 for impeller axles 3, on which two pairs of rollers 4 are rotatably mounted via roller bearings.
  • a pair of rollers 4 arranged one behind the other is used to guide U-shaped guide rails 5, which are connected to a support part 6b for the strip insertion device 6 and are long enough to protrude from the support part 6b.
  • the substructure 1 is arranged outside the band area determined by the length of the reel mandrel 7, so that the strip insertion device can optionally be moved outside the band area or within the band area in front of the reel mandrel 7.
  • Fig. 1 shows an embodiment with a transversely movable strip insertion device 6 with boom 6a.
  • the stationary substructure 1 has two pairs of bearing blocks 2 for impeller axles 3, on which two pairs of rollers 4 are rotatably mounted via roller bearings.
  • the arm 6a is pivotally arranged in a known manner with respect to the support part 6b of the strip insertion device 6, in that the support part 6b is provided with a pivot axis 10 for two pivot levers 11, which can be pivoted together by a hydraulic servomotor 12 which oscillates at 13 Support tabs 14 of a guideway 5 is fixed.
  • the arm 6a is connected in an articulated manner via a pair of lugs 15 to a hinge pin 16 at the free end of the swivel arms 11 and is supported by a pair of rollers 17 on curved tracks 18 of the support part 6b.
  • This type of swivel guide for the boom 6a is already described in the German utility model 7718 103.
  • the rollers 4 are height-adjustable via eccentric bearings, not shown, in order to be able to adjust the strip insertion device 6 relative to the reel mandrel 7 if, due to the weight of the strip insertion device with unsupported support via the projecting u-shaped guide rails 5, inaccuracies due to the deflection of the guideways or the like should occur.
  • 1 guide rollers 19 are mounted in the substructure with a vertical axis, which are pressed against an end face of the rollers 4 and laterally adjustable via eccentric bearings, not shown.
  • a toothed rack 20 is fastened, into which a toothed pinion of a motor carried by the substructure 1 engages (not shown).
  • the strip insertion device here only consists of the extension arm 6a, which corresponds to that according to FIG. 1, but is arranged such that it can be pivoted without housing via tabs 21 on a stationary pivot axis 22.
  • the pivot axis 22 is carried by stationary bearing blocks 23 in such a way that the entire strip insertion device is arranged in the belt area in front of the reel with the reel mandrel 7.
  • At least one hydraulic servo motor 24 is used for pivoting the boom 6a, which is fixed in an oscillating manner at 25 and is articulated at 26 to swivel brackets 27, which are rotatably mounted on the swivel axis 22 in addition to the brackets 21.
  • the swivel brackets 27 carry stop blocks 28 which limit the swivel path of the brackets 21 and normally always bear against the stop blocks 28 under the weight of the cantilever arm 6a. This makes it possible to swing the boom 6 a away from the reel mandrel 7 in a counterclockwise direction in order to clear the space in front of the reel for threading the split strips, although the strip insertion device is arranged stationary in the band area.
  • the telescopic extension of the boom 6a by means of an adjusting device 29, which is also necessary for other reasons, supports this clearing by the boom 6a being drawn into the device 29 when it is pivoted away.
  • the arm 6a could also be pivoted downwards about the hinge pin 26 in a clockwise direction if a detachable mounting for the pivot axis 22 is provided. If the tabs 21 and 27 are wedged on the pivot axis 22, the stop blocks 28 can be omitted.
  • FIG. 3 shows a top view of the front part of the arm 6a with the part of the cassette divided into exchangeable individual cassettes.
  • a main cassette 30 (FIG. 4) with the side walls 30a, the rear transverse wall 30b and the bottom wall 30c can be seen.
  • the main cassette 30 is connected to side bearing eyes 32 by screws 31. These bearing eyes 32 are mounted on an axis 33, the meaning of which will be explained later.
  • the main cassette 30 is firmly connected via flanges 34 to the remaining part of the extractor 6a with the telescopic adjusting device 29.
  • the main cassette 30 is connected with its side walls 30a by means of screws 36 to projecting end shields 37, in which, in a known manner, a feeler roller 38 bearing on the outer circumference 8 'of the narrow-band bundle and a drive roller set with this drive roller with a drive roller 39 and a counterpressure roller 40 are mounted , all of which have the shape of rollers and extend over the entire width of the belt area, which is denoted by B max in FIG.
  • the driving roller set 39, 40 is preceded by converging "guide walls 41, 42 which guide advanced strips between the rollers 39, 40.
  • the driving roller 39 is from the sensing roller 38 a toothed belt 43 driven, which is rotated while resting on the outer circumference 8 of the narrow-band bundles.
  • a plurality of interchangeable individual cassettes 44 to 48 can be hung next to one another in the main cassette 30, FIG. 3 clearly indicating that these individual cassettes are adapted to the cutting program, i.e. the width of the individual slit strips have different widths in order to be able to accommodate strips of corresponding width.
  • a pack of paper strips 49 is inserted, which has a slightly smaller width than the width of the individual cassette 44. In such a case, the pack of paper strips 49 is secured by light spring elements 50 inserted laterally.
  • each individual cassette 44 to 48 can be inserted into the extension 6a or the main cassette 30 in any lateral relation.
  • each individual cassette has an angle 52 in its rear transverse wall 51, the horizontal leg of which can be placed on a bar 53 on the inside of the transverse wall 30b of the main cassette 30.
  • Via a toggle 54 inserted into the horizontal leg of the angle 52 the rear wall 51 can be clamped at any point on the continuous bar 53.
  • the angles 52 are only partially visible in the top view according to FIG. 3 for the narrow individual cassettes 45 to 47, since they are otherwise covered by the insertion arms 55 lying above them.
  • the main cassette 30 could be formed back to the side walls 30a, i.e. practically as a cassette.
  • main cassette 30 is detachably connected to the cantilever arm 6a in this case and is therefore interchangeable in order to prepare a main cassette with selected individual cassettes of a certain width and certain lateral relation for a changed cutting program and when changing the cutting program against the in the cassette inserted in the strip insertion device.
  • a rod 58 with displaceable pointers 59 could serve as a setting aid, as can be seen in FIG. 3 and is used here for adjusting the individual cassettes 44 to 48 on the rear wall 30b of the main cassette 30.
  • the aforementioned movable insertion arm 55 is used in a known manner, with an insertion roller 60 which is locked against rotation in the direction of insertion of the strips (FIG. 4).
  • the already mentioned axis 33 is used for the rotationally fixed mounting of a plurality of pivoting levers 61 and 62 (FIG. 5) for actuating the insertion arms 55.
  • Swivel levers 61 and 62 are also not to be seen, since they are arranged within the insertion arms 55 which are U-shaped in cross section.
  • the common axis 33 or 63 (FIG. 5) is rotatably connected at both ends to cranks 64, on which bifurcated piston rods 65 of pressure medium-operated servomotors 66 engage, which are connected at 67 to the boom 6a or the main cassette 30 .
  • the common axis 33 or 63 can be rotated between two rotational positions via the servomotors 66.
  • the length of the common axis 33 between the cranks 64 has a square cross-section 33a, with which the swivel levers 61 together with the insertion arms 55 articulated at 68 can be secured in any lateral relation by means of a locking screw 69.
  • U-shaped receptacles 70 are used, which can be designed with the swivel levers 61 as a unit or as a loose type of adjusting ring.
  • the pawl 72 is shown locked, so that the insertion roller 60 is locked in advance of the insertion arm 55 and expediently pushes the uppermost paper strip of the stack 49 forward between the guide walls 41, 42 so that the paper strip from the drive roller set 39, 40 is detected and is inserted under the relevant incoming narrow band.
  • the basic idea of the exemplary embodiment according to FIG. 4 is that the locking of the insertion rollers 60 can be switched on selectively by remote-controlled means.
  • the insertion roller 75 is, as is known, a roller with freewheel, that is to say with automatic blocking in one direction of rotation.
  • the selective front pushability of paper strips enables the rotationally fixed connection of the pivot lever 62 to the common axis 63 to be selectively switched on by remote-controlled means.
  • These remotely controlled means each consist of a pivoting lifting magnet 76 carried by the pivoting levers 62 and which actuates a locking pin 77 which arrives in a rotationally fixed connection with the axis 63.
  • this locking pin 77 is piloted, passes through the hub 62a of a pivot lever 62 and presses against a flattening of the common axis 63.
  • the solenoids 71 and 76 can be selectively selected from a control panel, possibly also several at the same time, after which the servomotors are actuated in order to allow the selected insertion arms 55 with insertion rollers 60 and 75 to act to advance a paper strip.
