Definitions

  • the invention relates to a band storage device, consisting of an outer ring of drivable support rollers arranged radially with respect to the vertical ring axis for the upright reception of an outer coil with an inlet from the outside, from a concentric inner ring of freely rotatable, radial support rollers for one with the outer tape reel connected by a deflection loop inner tape reel and from a roll core forming a winding core for the inner tape reel, from the axially parallel rollers of which the tape leads as an idler roller to an inclined take-off roller within the roller basket.
  • the metal band entering the band store is wound from the outside onto an outer band wrap which rests on its edge on an annular rotary table or on an outer ring of drivable, preferably conical, idler rollers. Since this outer tape roll does not require a roll cage as the winding core, the inner diameter of the outer tape roll is only determined by the ratio of the tape feed speed to the number of revolutions of the table.
  • the tape runs over a deflection loop to an inner tape roll, which is received by an inner ring provided within the ring-shaped rotary table by freely rotatable supporting rollers and which is supported on a winding core from a roller basket, which encloses an inclined take-off roller , via which the tape is drawn from the inside of the inner tape roll in the opposite direction to the direction of rotation of the incoming tape by a basket roller serving as a reel from the tape store. Because of the connection of the two concentric Tape winding over a deflection loop, the tape is wound up with the same number of turns on the two tape coils during storage due to the deflection loop rotating at a speed corresponding to half the difference between the tape entry and the tape exit speed.
  • the size of the deflection loop depends on the strip thickness and, in particular in the case of thicker strips, requires comparatively large bending radii, which requires correspondingly large outside diameters for the rotary table.
  • the compressive forces exerted on the belt in the region of the deflection loop on the side of the outer belt winding can cause the belt to buckle.
  • the position of the outer tape roll on the turntable is not stable due to various influences.
  • a disadvantage of this known tape storage device is, above all, that the diameter changes of the tape rolls have to be taken into account by a radial displacement of the rollers of the roller baskets, which considerably increases the construction effort.
  • the invention is therefore based on the object of improving a strip store of the type described at the outset with simple structural means so that it is suitable for thin as well as for thick sheet metal strips, and that its outside diameter is comparatively small regardless of the respective strip thickness can be chosen and that there is a stable position for the outer tape reel
  • the invention achieves the stated object in that a deflection roller which can be driven around the rim axis at a rotational speed corresponding to half the difference between the winding and the winding speed of the storage device is provided between the outer and inner rings of the support rollers for the deflection loop, and that
  • the outer rim of the idler rollers has a rim of inclined rollers on the inside, which rises radially inwards and / or is inclined in the opposite direction to the circumferential direction of the outer tape winding with respect to a radial orientation with respect to the rim axis
  • the bending radius for the deflection loop of the tape is determined by the radius of the deflection roller and not by that of the Strip thickness and the free bending behavior of the strip depending on the strip material, so that when the deflection roller is designed for the smallest permissible bending radius of the strip, which requires the largest bending radius from the strips suitable for the accumulator, all strips form the same deflection loops and the outside diameter of the strip accumulator also can be kept comparatively small for thick belts.
  • the tensile forces exerted on the belt in the region of the deflection loop by the deflection roller not only ensure that the belt is attached to the jacket of the deflection roller, but also enable the storage of thin belts because they do not buckle of compressive forces otherwise occurring in the deflection area is more possible
  • a stable position of the outer tape reel must be provided, which is not supported by a roller basket or the like.
  • the ring of inclined rollers is used provided that penetrated the succeeded in their area of inner turns of the 1 outer tape pack due to their oblique position again radially outwards, so that a stable equilibrium condition results can len the inclination of the Schragrol ⁇ be both an inmits ⁇ chtung of the tape roll ver convinced ⁇ de axis and about a vertical axis
  • the position of the inner turns of the outer tape roll can be determined so that constant working conditions are present for the loop-forming deflection roller between the two tape rolls agrollen be provided in the area of their inner end with a thrust collar, which provides a guide for the inner winding of the tape winding without hindering the unwinding of the innermost tape winding.
  • the support rollers of the outer ring can be arranged sloping inwards, which stabilizes the position of the outer tape winding also supported
  • the control of the drive for the deflection roller between the two tape windings must be controlled as a function of the tape feed and the tape outfeed speed of the tape storage device.
  • the application of the tape to the jacket of the deflecting roller is responsible, the speed control of the drive for the deflecting roller, a control of the torque depending on the thickness and the width of the tape to be stored can be superimposed.
  • FIG. 1 shows a band store according to the invention in a schematic axial section
  • FIG. 2 shows this band store in an axis-normal section along the line II-II of FIG. 1,
  • FIG. 3 shows a part of the tape storage in a plan view in the region of a supporting roller of the outer ring, which cooperates with an oblique roller, on a larger scale
  • FIG. 4 shows the oblique roller and the supporting roller according to FIG. 3 in a side view.
  • the tape storage device essentially consists of a frame 2 which surrounds a table 1 in an annular manner and which carries an outer rim of driven support rollers 3 which are aligned radially with respect to the rim axis for the upright reception of an outer tape roll 4a.
  • the table 1 has a concentric inner ring of likewise radially aligned support rollers 5, which are freely rotatable and extend radially outward from a roller cage 6, as can be seen in particular from FIG. 2.
  • a deflection roller 11 is provided, which is freely rotatably mounted on an arm 12 of a rotating ring 13 and can be rotated around the table 1 with this rotating ring 13.
  • the turntable 13, which is rotatably mounted on the table 1 is provided with a toothed ring 14, which with e ; Nem pinion 15 combs.
  • a motor 18 connected to a gear 17 via a cardan shaft 16 is provided, so that with the aid of the deflection roller 11 between the outer tape roll 4a and an inner tape roll 4b, which is wound onto the roller basket 6 and edgewise supported on the support rollers 5 of the inner ring, a deflection loop 19 can be pulled, to the A support roller 20 is supported on the arm 12 for the deflection roller 11.
  • the belt 8 which runs into the belt storage device via a belt inlet 21 formed from a pair of rollers, reaches the support rollers 3 of the outer ring which, according to FIG. 1, are driven by a motor 22 with the interposition of a corresponding gear 23 via articulated shafts 24 and angular drives 25 be.
  • the belt conveyance via the driven idler rollers 3 of the outer ring causes the band entering the band storage device to be wound into a band wrap 4a on the idler rollers 3.
  • a ring of oblique rollers 26 is assigned to the outside of the idler rollers 3 on the inside, which according to the exemplary embodiment on the one hand rise towards the ring axis (FIG.
  • the tape From the innermost turn of the outer tape roll 4a, the tape merges in a deflection loop 19 into the inner tape roll 4b, which is wound onto the roller cage 6 from the outside, the tape 8 moving inward from the innermost turn via the discharge roller 9 to the inclined take-off roller 7 from which it runs out of the tape storage. If the tape 8 is only stored in the tape store, ie no tape is removed from the memory, the deflection roller 11 rotates at half the tape feed speed, the Tape with the same number of turns is wound on the inner and outer tapes 4b and 4a.
  • a control device 28 is provided, which is connected on the one hand to a speed sensor 29 for the tape 8 entering the tape store and on the other hand to a speed transmitter 30 for the tape leaving the tape store, as indicated in the block diagram in FIG. 1 becomes.
  • the motor 18 for the deflection roller 11 is controlled, by means of which the deflection loop 19 is advantageously formed, largely independently of the sizes and properties of the belt used in each case.
  • the torque of the motor can also be regulated via the control device 28.
  • the strip thickness is input via an input 31 into the control device 28 which, based on a predetermined dependency between the strip thickness and the required torque, provides a setpoint torque which is compared with the actual torque detected by a torque sensor 32, so that in the case of a setpoint / actual value difference a corresponding comparison can take place.
  • additional influencing variables such as the width of the strip to be stored or material properties, for controlling the torque of the motor 18 and thus the effective tensile stresses in the area of the deflection loop 19 can be taken into account.
  • an outer roller basket 33 is provided, the basket rollers of which are designated by 34.
  • this roller cage 33 is not absolutely necessary for the actual tape storage in two opposite tape coils 4a and 4b, which are connected to one another by a deflection loop 19, as are the support rollers 35 and 36 for the tape in the area between the discharge roller 9 and the take-off roller 7 and can possibly be omitted for the outgoing belt after the take-off roll.
