Definitions

  • a tape winding apparatus comprises a tape supply and a tape'winding mandrel receiving tape from the supply and winding the tape in form of a coil.
  • a tape guide channel is arranged upstream of the mandrel and is elongated in the direction of approach of the tape. The tape guide channel confines the tape against movement in lateral direction to assure that the radial faces of a coil wound from the tape will be entirely planar.
  • a friction pad or the like engages one major surface of the advancing tape within the confines of the channel.
  • the present invention relates to a tape-winding apparatus in general, and more particularly to an apparatus for winding elongated tapes into coils. Still more particularly the invention relates to an apparatus for winding metal tapes into coils.
  • edge portions of convolutions which project outwardly from the edge portions of other convolutions can be readily bent, torn or damaged during handling, transportation, storage or the like, and tape sections so mutilated are not suitable for further use, aside from the fact that such damage greatly complicates subsequent unwinding of the tape from the coil.
  • a further disadvantage of the known tape-winding devices is the fact that they are not suitable for automated operation.
  • a further object of the invention is to provide a tape-winding apparatus wherein the lateral edges of all tape convolutions of a tape wound into the shape of a coil are located in a common plane.
  • An additional object of the invention is to provide such a tape-winding apparatus which is suitable for automated production.
  • a tape-winding apparatus which, briefly stated, comprises tape supply means which supplies tape to be wound in form of a coil.
  • Tape-winding means is spaced from the tape supply means and is operative for receiving from the latter tape which advances in a predetermined path, and for winding such tape to thereby form a coil thereof.
  • Tape guide means is located upstream of the tape-winding means and comprises wall means defining an elongated guide channel surrounding a portion of the predetermined path and defining the tape against movement laterally of this path.
  • friction-brake means comprises an engaging portion which extends into the guide channel and which slidably frictionally engages a major surface of the tape as the same advances through the guide channel so as to exert a frictional braking action on the tape.
  • the tape is caused to form a free-hanging loop upstream of the tape guide means.
  • the provision of the tape guide means prevents any lateral movement of the tape immediately upstream of the winding mandrel onto which the tape is wound, and the friction-brake means provides for precisely controllable braking of thetape.
  • the mandrel and the drive motor for the mandrel are, in accordance with the present invention, jointly mounted on a common support, such as a machine frame, together with the tape guide means, thereby assuring that any vibrations which might develop, for instance from operation of the drive motor, are equally transmitted to the tape guide means and to the winding mandrel so that the two will perform any resulting movements in unison, that is that they will not move relative to one another.
  • the provision of the loop serves to isolate the tape advancing through the tape guide means from any vibrations or the like which might occur as a result of operation of the tape supply means.
  • FIG. 5 is a view, partly in section, taken along the line V-V of FIG. 3',
  • FIG. 6 is a view, partly in section, taken along the line VI VI of FIG. 5;
  • FIG. 7 is a fragmentary sectioned detail view of a portion of the apparatus illustrated in FIGS. 3-6.
  • FIGS. 1 and 2 An apparatus embodying the basic concept of my invention is illustrated in FIGS. 1 and 2. It comprises a base 10 carrying a machine frame 11 on which in turn there is mounted a motor-transmission unit 12 which is of known construction and therefore not illustrated in detail. In conventional manner the unit 12 has an output shaft on which there is mounted a flywheel 13 and a winding mandrel 14 the longitudinal axis of which latter extends at least substantially horizontally.
  • the frame 11 further carries two guide rods 19 which extend normal to the plane of FIG. 1.
  • the guide rods 19 are mounted in and secured to the frame 11 by the arms 19a.
  • a block member 20 is. mounted on the guide rods 19 for movement in direction normal to the plane of FIG.
  • Reference numeral 16 identifies three handwheels provided on the frame 11, these handwheels 16 being operatively connected with the block 20 via drive trains 18. More specifically, one of the handwheels 16 is connected via its associated drive train 18 and the diagrammatically illustrated bevel gears 17 with a threaded rod 17a extending in parallelism with the guide rods 19 and located intermediate the same.
  • An inter' nally threaded sleeve (not shown) is mounted in or on the block member 20 and its internal threads mesh with the external threads of the threaded rod 17a. Accordingly, when the respective handwheel 16 is turned, the threaded rod 17a is similarly turned with the result that. the block member 20 moves in direction normal to the plane of FIG. 1.
  • Additional guide rods 15 are mounted in the block member 20 for movement relative to the same in the direction of the doubleheaded arrow 21, that is for vertical movement. Such vertical movement is accomplished by rotation of another one of the handwheels 16 which is linked in suitable manner well known to those skilled in the art (and. not illustrated in detail) with the guide rods 15.
  • a plate 22 is connected to the upper ends of the guide rods 15 as shown in FIG. 1, and a support plate 23 is coupled with further guide rods 231 which are mounted in the plate 22 in such a manner as to be movable in direction of the doubleheaded arrow 24, that is in horizontal direction.
  • the third of the handwheels 16 is operatively associated via its drive train 18 and the diagrammatically (dot-dash-dot lines) illustrated transmission is connected with the guide rods 231 and effects movement of the same in the direction of the double-headed arrow 24. It is thus evident that the support plate 23 can, by rotation of the three handwheels 16, be adjusted in three mutually normal directions, that is in direction normal to the plane of FIG. 1, as well as vertically and horizontally.
  • guide channel means for a tape to be wound into the form of a coil is mounted on the support plate 23.
  • This tape guide means comprises two wall portions transversely spaced from one another and extending at least in substantial parallelism with one another on the upper surface of the support plate 23.
  • These wall portions or elements are identified with reference numeral 26 and each comprise an upper strip-shaped member 27 and a lower stripshaped member 28.
  • the upper member 27 consists of metal and the lower member 28 consists of polytetrafluorethylene or a material having analogous characteristics with respect to coefficient of friction, abrasion resistance, hardness and the like.
  • the inner edges of the members 28 are bevelled in outward direction so that the cross-sectional configuration of the resulting tape guide channel 30 defined between the members 28 is substantially trapezoidal.
  • Screws 29 or other fastening means are used to connect the elements 26 to the support plate 23, preferably in such a manner that at least one of the elements 26 can be adjusted in direction towards and away from the other element 26 so as to vary the width of the tape guide channel 30 in order to accommodate the same to the use of tapes having different widths.
  • the width of the tape guide channel 30 is so selected that the tape 40 ad vancing therethrough has no lateral play transversely of its direction of advancement, that is transversely of the path in which it advances, or has only negligible play.
  • the upper surface of the support plate 23, which constitutes the bottom face of the tape guide channel 30 over which the tape-40 slides, and also the upper surface of the plate 22 as well as the inwardly directed bevelled edge faces of the members 28 are coated with polytetrafluorethylene or an analogous material as discussed above.
  • a friction-brake arrangement is provided for exerting a controlled amount of frictional braking force upon the tape 40 as it advances through the guide channel 30.
  • uprights 31 which are connected laterally to the support plate 23 (compare FIG. 2) and which extend upwardly therefrom.
  • the upper ends of the uprights 31 have mounted thereon a shaft 35 which is turnable about its longitudinal axis.
  • an arm 32 Secured to the shaft 35 and projecting upwardly therefrom is an arm 32 whose free end carries a rod 33 on which a weight 34 is mounted for sliding movement in longitudinal direction.
  • the diagrammatically illustrated setting screw associated with the weight 34 enables the latter to be secured against sliding movement relative to the rod 33 at any selected position of the latter.
  • a further rod or arm 36 is provided on the shaft 35 extending approximately in parallel with the rod 33 and having secured at its free end a member 37 which extends from above through the upper open side into the guide channel 30.
  • the member 37 carries an engaging portion 38 which frictionally engages the upper major surface of the tape 40.
  • the engaging portion 38 may consist of or have a free surface consisting of felt, polytetrafluorethylene or an analogous material.
  • the weight 34 will exert a lesser or greater weight upon the frictionbrake means consisting of the member 37 and the portion 38, so that the latter is correspondingly pressed with lesser or greater friction against the upper major surface of the tape 40, thereby braking the tape in the tape guide channel 30.
  • a further upright 43 is provided on the base and carries in the region of its upper free end a shaft 45 on which there is mounted a tape supply roll 44.
  • the tape 40 advances from the roll 44 in a predetermined path to the tape guide channel 30, as clearly evident from FIG. 1.
  • the arrangement is such as to assure that the tape 40 will always form a free-hanging loop 42 intermediate the roll 44 and the tape guide channel 30. This is to assure that any vibrations or other move ments originating in the tape supply means are isolated from and will not be transmitted to the portions of the tape advancing through the tape guide channel 30.
  • the direction of advancement of the tape 40 is identified with reference numeral 125.
  • I may provide an arrangement for assuring that the loop 42 is permanently maintained.
  • a further upright 46 may be provided on the base 10 and may carry two light sensors 47 and 48 which latter may be so mounted that they can be adjusted longitudinally of the upright 46, that is that their height can be varied, as well as their distance from one another.
  • the supply roll 44 can be driven in rotation in a sense unwinding tape 40 therefrom by a suitable drive, as well as being brakes, with reference numeral 41 diagrammatically indicating the combined drive and brake arrangement for the supply roll 44.
  • Electrical conductors 49 connect the sensors 47 and 48 with the device 41, the arrangement being such-and this is well known to those skilled in the art-that a signal is generated by the upper sensor 47 if the loop 42 becomes too short, the thusgenerated signal serving to cause the device 41 to be activated or to increase the speed of rotation of the supply coil 44, whereas the lower sensor 48 is activated and generates a signal if the loop 42 becomes too long, this latter signal serving to effect retardation in the rotation of the supply roll 44.
  • the apparatus serves to wind a single coil of tape. It need hardly be emphasized, however, that by duplicating the number of tape supply rolls 44, the number of winding mandrels 14, and the number of tape guide channels 30and the various associated components-any desired number of tape coils can be wound simultaneously.
  • the elements 26 are adjusted with respect to one another so as to obtain a tape guide channel 30 of a width requisite for preventing lateral movement of the tape 40 which is to pass therethrough. Thereafter, the leading portion of the tape 40 is passed below the contact portion 38 of the friction-brake and is connected to the winding mandrel 14 or to a bobbin or reel mounted on the mandrel 14 for rotation therewith. Now the three handwheels 16 are turned until the tape guide channel 30 is exactly aligned with that part of the mandrel l4or the reel provided on the mandrel 14-to which the leading end of the tape 40 is secured. Now the drive 12 is energized and winding begins.
  • the provision of the tape guide channel 30 assures that there is no lateralmovement of the tape 40 immediately upstream of the winding mandrel 14, so that the coil which is wound on the latter will have completely smooth end faces, that is the edges of the individual convolutions of tape on the coil will be located in a common plane at each opposite end of the coil. If the diameter of the coil is relatively large, then gradual readjustments in the positioning of the tape guide channel 30 may be made by turning the handwheels 16 as the diameter of the coil grows, in order to maintain the distance between the outlet of the tape guide channel 30 and the circumference of the coil as small as possible. It goes without saying that the handwheel 16 which effects movement of the block member 20 in direction normal to the plane of FIG. 1 will not be turned during such operation. It also goes without saying that the friction brake 37, 38, and its associated weight 34, have been shown by way of example only, and that other possibilities exist and will suggest themselves readily to those skilled in the art. Thus, the weight 34 could be replaced with an adjustable spring or an adjustable spring arrangement.
  • FIGS. 1 and 2 illustrate the apparatus according to the present invention in its basic principle. Such apparatus is admirably suited to automated production of tape coils with mass-production methods.
  • the apparatus shown in FIGS. 3- 7 is exemplary of such automated production, and incorporates the principles of the apparatus discussed above with respect to FIGS. 1 and 2.

  • a coaster arrangement is associated with the pinion 54 (not shown but of conventional type) and assures that reciprocation of the piston of the cylinder and piston arrangement 56, and nsequent advancement of the rack 55, effects rotation of the rotary plate 52 only in direction of the arrow 57 shown in FIGS. 3 and 4.
  • the rotary plate 52 carries three winding mandrels 58 which are equiangularly spaced from one another.
  • FIG. 7 shows details of the construction of the winding mandrels 58. It will be seen that each of them is composed of a hollow tubular member 60 provided adjacent one end with an outer circumferentially extending shoulder 61 which is located immediately adjacent a bore through which the end portion of the respective tubular member 60 extends. It is clear from FIG. 7 that the tubular member is rotatable with respect to the rotary plate 52.

  • the cam rod 64 is provided with conically tapering cam faces 65 which are so constructed that, when the cam rod 64 is in the position shown in FIG. 7, they deflect the spreading pins 63 radially outwardly with the result that the contacts members 59 are also spread radially outwardly.
  • the contact members 59 will be spread into tight frictional engagement with the inner surface in the hub of the respective reel or bobbin, thus connecting the same tightly to the respective mandrel 58. If the cam rod 64 is moved towards the left in FIG. 7, the pins 63 can be moved inwardly and can be withdrawn into the bores, permitting the contact members 59 to move inwardly into contact with the outer surface of the tubular members 60, thereby enabling withdrawal of the reel or bobbin from the respective winding mandrel 58. It is advantageous to provide spring-biased arrangements (not shown) to deflect the contact members 59 inwardly into contact with the outer surface of the tubular member 60.
  • a further pin 81 is slidably received in a radial bore 80 which is provided in the shoulder 61.

  • a rod 82 can enter through the hollow end portion 62 of the tubular member 60 and will, upon contact of its bevelled front end with the pin 81, urge the same radially outwardly in the bore 80. This, in turn, results in radially outward displacement of the pin 76 by the pin 81, so that the free end portion of the pin 76 is urged out of the bore 80 with the result that now the winding mandrel 58 can rotate relative to the rotary plate 52.
  • a conventional counter for counting the number of rotations of the winding mandrel 58 can be operatively associated with the pin 76, so as to begin counting the same as the free end of the pin 76 is urged out of the bore 80 and rotation of the mandrel 58 can begin.
