Definitions

  • the invention relates to a fully automatic winding device for winding up strips or ribbons, particularly strips of metal or plastic foil for the purpose of producing finished rolls of wound-up material.
  • Winding devices of the general type above referred to as now known comprise a spindle for a take-up spool which is driven with a constant speed.
  • the gradually increasing diameter of the take-up spool and of the material wound thereupon causes a corresponding increase of velocity with which the material is wound upon the spool.
  • the pull tension with which the material is wound-up changes continuously as the winding operation progresses.
  • suitable retarding means such as brakes or costly speed controls must be provided to effect a constant reduction of the rotational speed of the wind-up spindle.
  • the continuous change in the pull tension tends to cause, especially with stretchable and thin foils or similar material, wrinkles, a reduction of the width of the foil or similar material, deformed edges due to lateral sliding of the material to be wound up and also different thickness of the wound-up layer of material on a finished roll.
  • Two pressure rollers are driven without slippage and with a substantially uniform circumferential speed so that the material to be wound is drawn by the driven pressure rollers in coaction with the take-up spindle which in turn is driven by the rollers.
  • the material is thus pulled off from an equally driven supply spool at a continuously controlled pull tension.
  • the winding device provides that both pressure rollers are driven without slippage and the rollers in turn drive the freely rotatable take-up spindle. Since the diameter of the pressure rollers remains constant, the circumferential speed of the pressure rollers also remains the same when, as is the case, the rollers are driven with constant rpm. Hence, the circumferential speed of the take-up spindle and thus also that of the material to be wound upon the spindle remains constant, thereby obtaining a uniform and constant speed of the winding up of the material.
  • the take-off spindle of the supply spool is also freely rotatably and floatingly supported and is equipped with a retaining device. This device prevents axial or radial sliding of the supply spool on its spindle.
  • the structural arrangement of the take-off spindle and of the retaining device assure a smooth rolling off of the material without the heretofore generally used braking means such as friction braking means and the time-consuming adaptation of the rim of the supply spool to the path of the material during the winding operation.
  • the supply spool is thus secured to its spindle and also secured against becoming loose during a winding operation.
  • the circumferential surface of the supply spool that is, not the take-off spindle itself, is driven by a driving device for effecting circumferential drive of the supply spool.
  • This device for instance an endless belt, adapts itself automatically to the varying diameter of the supply spool and is pressure-loaded, for instance by hydraulic, pneumatically, mechanically or electrically operated auxiliary devices or a combination of such devices.
  • the afore-referred to driving arrangement is particularly advantageous when the material consists of foils which are very thin and stretchable since the pull tension during the winding operation is not affected by high swinging moments of brakes, varying friction coefficients or gradual reduction of the outer diameter of the supply spool.
  • a further advantage of the described driving arrangement is that the take-off spindle and the driving arrangement are connected to a laterally displaceable unit and are further connected to an automatically functioning control of the edges of the path of the material. The uncontrollable sliding of the edges of the material if the supply spool is irregularly wound is thus prevented.
  • Both pressure rollers and the endless driving belt of the driving arrangement for the circumferential driving of the supply spool are driven from a common driving device which includes two variable speed drive means with gradual speed adjustment.
  • the driving shaft of one gradually speed variable drive means via a pulley and a slipless drive belt drives both pressure rollers.
  • the driven shaft of the second gradually speed variable drive means drives via a pulley and a slipless drive belt the endless driving belt of the circumferential drive for the supply spool.
  • a so-called floating or idling roller is disposed between the take-off point (supply spool) and the take-up point.
  • This floating roller applies pull to the path of the material by means of a pre-selected weight load thereby controlling the pull tension.
  • the floating roller automatically regulates such changes by controlling the rotational speed of the second gradually variable speed drive means.
  • Increasing or reducing the rotational speed of the second drive means for the supply spool effects a corresponding change in the circumferential speed of the endless drive belt and thus also the circumferential speed of the supply spool.
  • this arrangement effects a constant adaptation of the circumferential speed of the supply spool to the constant speed of the material as it is being wound and also to the constant pull tension.
  • the embodiment provides that the spindles at their ends facing the turret head mount a drive wheel and that a driving device is provided so that each of the spindles can be driven by this driving device when the spindle has left the wind up position.
  • the driving device takes over the drive of the corresponding spindle in that such spindle or a wound roll fitted thereupon is no longer driven by the driven pressure roller.
  • the driving device consists of at least one further belt pulley and a driving belt.
  • the separation or cutting of the material is effected automatically and it is also automatically assured that the new leading end obtained by cutting or separating the material is brought to the next following wind up spindle or roll thereon.
  • at least one of a smaller one of the pressure rollers is temporarily provided with a feed-in device for engaging said roller.
  • This feed-in device is preferably loaded by springs and/or hydraulic and/or pneumatically operated auxiliary means similar to those used for the pressure rollers.
  • Cutting of the material is effected by suitable means such as a serrated knife or glowing wire.
  • suitable means such as a serrated knife or glowing wire.
  • the feed-in device for the material is pressed by a pressure means against the driven smaller pressure roller.
  • the leading end of the material for the next spindle or roll to be wound is gripped and is wrapped about a sleeve on the spindle by the feed-in device, which is preferably disposed underneath the respective roll.
  • a speed acceleration device which accelerates the take-up spindle possible with a sleeve thereon to the required rotational speed.
  • a winding device in the event that a winding device according to the invention is equipped with several take-up spindles which are freely rotatably and floatingly mounted on the turret head and that one already wound roll leaves its wind-up position, it must be assured that the wound up material on such roll is not loosened and again becomes unwound. To prevent such unwinding and loosening, the partly or completely wound roll must be held during the cutting or separating of the material and moreover simultaneously with reaching the next position provisions must be made so that loosening of the material is prevented.
  • the hertofore known winding devices are so constructed that retention of the material in its tight and correctly wound condition could not be accomplished.
  • the winding device permits convenient retention of the wound up material by the application of adhesive or wrapping a holding strip about the roll. It is merely necessary that above the wind up position a device is provided which by means of an adhesive strip or a label which may be printed if desired, the wound roll while still on the wind up spindle is wrapped or held together by adhesive. Obviously, such glueing or tying prevents the loosening of the wound material.
  • a wrapping device is mounted above the wind up spindle station similar to the mounting of the glueing device.
  • Such printing or decorating device effects printing or decorating of a finished roll simultaneously with the arrival of the roll at the location of the printing or decorating device.
  • the wind up or take-up spindle with the finished roll thereon must be driven.
  • driving is effected by a driving device and the already previously mentioned driving wheel on the back side of the turret head which is fixedly coupled to the wind up spindle.
  • the glueing device and also the wrapping device are automatically removed from the path of the rolls and the wind up spindles.
  • this step is effected by grippers and/or laterally displaceable support cones which support the roll during the wind ing thereof.
  • the gripper may damage the surface or the edges of the finished roll, depending upon the type or properties of the material to be wound. If only support cones are used and there are no grippers, the support cone is released by lateral displacement to drop into a container or upon a conveyor band. Depending upon the properties of the sleeve upon which the material has been wound and the structure of the support cone, it can occur that the wound up spool remains hung up on the cone thereby causing an interruption of the operation.
  • disassembly is effected by automatic loosening of the retaining device incorporated in the wind up spindle. Such loosening first releases at the sleeve upon which the material has been wound.
  • This operation is effected for pressing in the end of the slidablc bolt behind the driving wheel which is fixedly secured to the wind up spindle.
  • Such pressing in of the bolt may be effected hydraulically, mechanically, electrically, pneumatically, or by a combination of this type of means.
  • a yieldably mounted fork-shaped stripper encompasses the wind-up spindle at an angle of about 180 and presses against the sleeve for the roll but not against the edge of the wound up material on the sleeve, as such pressure might cause damage to the material.
  • the wound spool is transferred to a conveyor band or fed into a carton placed in position for storing finished rolls therein.
  • the fork-shaped stripper is constructively so arranged that it is capable of moving not only axially for stripping a finished roll but also capable of performing a radial movement. This latter movement removes the fork-shaped stripper from the circular path ofthe windup spindle to permit return of the stripper into its initial position. After reaching this initial position, the stripper is pressed against the next following wind-up spindle and now encompasses that spindle at about an l80 angle for stripping the next finished roll. All the operational movements of the fork-shaped stripper as hereinbefore described are automatic.
  • an empty sleeve is axially slid upon a bare wind up spindle and positioned to receive an empty sleeve.
  • the sliding ofa sleeve upon a spindle is automatically effected by applying the required force (hydraulic, mechanical, electrical or pneumatic) whereby the sleeve and the spindle are correctly positioned, that is, the location of the sleeve is adapted to the path which the material follows during the winding operation.
  • a finger which is axially movable and also radially movable about a turning point pushes an empty sleeve into the ready position upon the respective wind up spindle.
  • the point of rotation or pivotal movement for the radial movement of the fork-shaped stripper and for the just mentioned finger is common for both the stripper and the finger, that is, they are seated on a common shaft extending through the stripper and the finger.
  • the sleeve dispenser of the sleeve storage container or bin is equipped with an electrical, pneumatic. mechanical means or by a combination of these types of means activated fail detectors.
  • This detector in combination with a feeding device mounted on the storage bin activates the feed device, thereby filling the gap in the feed of empty sleeves as sensed by the detector.
  • upgrading or changing of the material to be wound can be effected.
  • the suitable location for upgrading or changing devices is between the supply spool and the idling or floating rol- Ier.

  • the driving shaft is located at the pivot pin 11 of pressure roller 5 (see FIGS. 1 and 2).
  • endless belt 72 is also coupled with the drive means for pressure rollers 4 and 5 (see FIGS. 1 and 2). Such coupling assures that the rotational speed of drive gear 60 is always substantially the same as the rotational speed of the material changes. Moreover, slackening or tearing of material I is avoided during the afore-referred to separation of the material.
  • FIG. 4 further shows a device for accelerating the driving gear 60 and thus also of the wind up spindle 3 from zero speed to a rotational speed or circumferential speed which corresponds to the running speed of material 1.
  • This device is located at the wind up spindle position 74 and consists of a preferably rubber covered driving wheel 73 driven by a suitable motor, a pivotal holder 75 mounted by an arm on a pivot pin 77 and a pressure air operated cylinder-piston mechanism 76.
  • the driving wheel 60 which is driven by an endless belt 72 drives roll or sleeve 2 which is seated on the wind up spindle 3 thereby imparting a corresponding tension to the material travelling from spool 7 to roll or sleeve 2.
  • a holder 78 pivotal about a pivot axis 80, together with adjustable and exchangeable cutting means 79 such as a knife or glowing wire is moved against the pre-tensioned material 1 by means of a pressure air operated cylinder-piston assembly 81.
  • a clamping roller also mounted on the holder presses material 1 against the pressure roller 4 underneath the material. Cutting of material 1 occurs at point 82.
  • Wheel 60 which is still driven, pulls the respective end 83 of the material upwardly, that is, in the direction indicated by an arrow.
  • the driven pressure roller 4, which is the smaller one of the two pressure rollers, and the clamping roller 85 squeeze the end 84 of the material together, thereby forcing it into the rotational direction of pressure roller 4, indicated by an arrow.
  • the clamping roller 85 is rotated in the opposite direction and thus in between pressure roller 4 and wind up spindle 3 or sleeve 2.
  • the gap between roller 4 and spindle 3 or sleeve 2 contributes a feed-in zone which is held under pressure by the pressure air operated cylinder-piston mechanism 10.
  • the lead-in end 84 of the material is then fed into a feed-in zone formed by a feed-in roller 86 and sleeve 2 or spindle 3.
  • the end 84 of the material if necessary, is conveyed by pressurized air supplied from a nozzle 87 into a feed-in zone between pressure roller 5 and sleeve 2 or spindle 3.
  • the lead-in end 84 of the material is now gripped by the material 1 which is conveyed by pressure roller 5 and is wound without slipping about sleeve 2 or windup spindle 3.
  • the feed-in roller 86 is operated by a pressure air operated cylinder-piston mechanism 88.
  • FIG. 6 shows a driving device 94 for holding the end of the material, glueing the same for instance by a suitable adhesive covered strip, banding finished rolls or printing finished rolls wound upon sleeve 2 or directly on a wind-up spindle.
  • the driving device comprises a rubber covered drive wheel 89, drive pulleys 91 and 93 and a belt 92; it is pivotal about the pivot axis 90 and operated by pressurized air via cylinder-piston mechanism.
  • a drive motor for the device is not shown to simplify illustration.
  • Device 94 drives wheel 60.
  • FIG. 6 further shows the ends 83 and 84 of material 1 after the separation thereof has been effected.
  • FIGS. 7 and 7A illustrate the fully automatic removal of finished rolls from a spindle 3 and the simultaneous transfer of a conveyor band 108.
  • Removal of finished rolls is effected by a pull off finger 96 which is spring-supported (not shown).
  • the finger is guided by a guiding device 97 parallel to the axis of wind up spindle 3 against the edge of sleeve 2 or the edge of spindle 3 (in the event no sleeve is used for winding up the material) in a manner such that pulling off of a finished roll from a spindle 3 is effected.
  • the guiding device 97 is pivotally mounted on a shaft by means of an arm 98. Pivoting of pivot arm 98 removes the pull off finger 96 out of the circular path 9 of spindles 3.
  • Arm 98 is pivotal by a pressure air operated cylinder-piston mechanism 100.
  • the required movement of pull off finger 96 parallel to the pivot axis of arm 98 is effected by a pressure operated cylinderpiston mechanism 105.
  • winding of the material 1 on a sleeve 2 requires that this sleeve and the respective spindle 3 are secured against axial and rotational movement relative to each other by a locking device 107.
  • the locking device 107 In order to be able to withdraw a sleeve 2 with material wound up thereon from its spindle 3, the locking device 107 must be released. Such release is effected by pressing a slidable bolt 106 into the position 102. Movement of the bolt into this position is effected by a device 103 which in turn is operated by a pressure air activated cylinder-piston mechanism 104.
  • FIGS. 7 and 7A further show removal of the finished roll 101 by a pull off finger 96.
  • FIG. 1 shows the movement of a spindle 3 during turning of turret head 6 through 60 from the position 109 into the position 110.
  • Such change of the spindle 3 from position 109 to position 110 is used to count the number of finished rolls by a counter 111. If the material is wound directly upon a sleeve 2 and on changing from position 109 to position 110 the spindle 3 does not have a sleeve 2 thereon, a detector 1 17 stops the drive means for the winding operation.
  • a sleeve storage bin for continuously feeding sleeves to a sleeve dispensing device 122 is diagrammatically shown.
  • a sleeve feeding device is automatically activated.
  • This device consists of four or more toothed belt pulleys 1 13 and two or more belts 114 formed with teeth on both sides. Pulleys 113 are seated on two shafts 116 and are driven by a drive means 115.
  • the teeth on belts 114 and pulleys 115 are identical and uniformly spaced. As a result, during the feeding of sleeves from storage bin 112, the sleeves are fed by the outside teeth of belts 114 into storage bin 112 in horizontal position.
  • the inside teeth on belt 114 and the teeth on belt pulleys 113 assure a non-slipping engagement of the pulleys with the belts.
  • the sleeve dispenser 122 when in the position 123 can be separated from storage bin 112 by a suitable device (not shown). Such possibility of separation assures that for one storage bin 112 several dispensing devices 122 fitting sleeves having the desired different diameters can be installed or removed as required by the operation. Exchange of a dispensing device 122 does not affect the initial position and mounting of the storage bin 112 in the device.
  • the dispensing device 122 is provided with retaining lips 124 which can be made of steel, plastic, etc.
  • FIGS. 9 and 9A show a device for sliding a sleeve 2 upon a wind up spindle 3.
  • a push-on finger 119 pushes sleeves 2 out of dispenser I22 and upon spindle 3.
  • the sleeves are retainable on the spindles 3 in any selected position and thus in any desired position relative to the lengthwise edges of material 1.
  • FIGS. 9 and 9A show diagrammatically the actual sliding of a sleeve 2 on spindle 3.
  • the sleeve is shown partly in dispensing device 122 and partly on spindle 3. It is also shown that locking bolt 106 is pressed into the position 102 so that release of the locking device as it is necessary for sliding a sleeve, is effected.
  • the locking device is indicated at 107.
  • the movement of the push-on finger 119 which must occur parallel to the axis of spindle 3 is effected by a guide 97 and by pressure air operated cylinder-piston mechanism 105.
  • Guides 97 and mechanism 105 are secured to arms and pivotal on a shaft 99.
  • the pivotal movement of finger 119, guide 97 and pivotal arms 120 are effected by pressure air and a cylinder-piston mechanism 121.
  • FIGS. 9 and 9A show a device 103 for pressing in the slidable locking bolt 106 to release the locking device 107 incorporated in spindle 3.
