Definitions

  • This invention relates to a method of and apparatus for controlling the winding of strip material from a supply thereof onto an arbour, drum, former, reel or the like.
  • a method of controlling the winding of strip material onto an arbour, drum, former, reel or the like by guiding the strip material by way of spaced apart guide means so located with respect to each other as to allow a length of the strip material to droop catenary like between the guide means to provide a slack length in the strip material, and by controlling the material travel between the guide means so that the lowermost level of the slack length is maintained between two levels one above the other, characterised in that the strip material whilst in the slack length is guided by an edge or edge region thereof cooperating with a further guide means presenting a working surface which is inclined to the vertical.
  • apparatus for controlling the winding of strip material from a supply thereof onto an arbour, drum, former, reel or the like including spaced apart guide means so located in the feed path of the material from a supply thereof to a drum or the like, as to permit a length of the material to droop catenary like between the spaced apart guide means to provide a slack length in the strip material, means for controlling the rate of travel of the strip material through the slack length so that the lowermost level of the slack length is maintained between two levels one above the other, characterised in that further guide means are provided for presenting an inclined guide surface or the like to an adjacent edge or edge region of the strip material whilst it is in the slack length.
  • the slack length guide means comprises a plate or other surface which is inclined to the vertical in a fixed or selectively adjustable manner.
  • the buffer unit 2 includes a framework including a base 4 and support means or uprights 5, 6 which are secured or supported by a back plate 7.
  • the upright 5, 6 are so mounted from the base 4 that the plate 7 is inclined to the vertical.
  • the inclination is at a required angle.
  • the inclination can range between 1° to 30° with a particular range being between 5° to 15°.
  • Figure 3 shows an arrangement for enabling the adjustment of the inclination.
  • the arrangement includes pivoting the uprights 5, 6 to the frame 4 by pivots schematically shown.
  • a link or the like 8 is pivoted at one end thereof 9 to the base 4, there being one such link for each support 5, 6.
  • a lengthwise slot 10 is formed in each link and the links are secured to the uprights each by means of a retaining bolt or screw 11 engaging the slot and the uprights.
  • the adjustability can be achieved by arranging for the back plate to be pivotally mounted and the links or the like co-operating with the pivoted plate 7.
  • the buffer unit may be formed into a chamber 2A by mounting a front plate 12 or wall to the uprights 5, 6.
  • the front wall 12 would be transparent.
  • the back plate may be transparent so that the situation relating to the material passing through the chamber 2A may be readily noted.
  • the spacing adjustment means can comprise spacers or the like which are engageable with bolts provided for mounting the back plate 7 and the front plate 12 to the uprights 5, 6.
  • a strip material feed roller 13 is provided upon a support 14 located near the end wall or upright 5 and a second material feed roller 15 is provided on a support 16 located near the end wall or upright 6.
  • a sensing means 17 is provided in the vicinity of the feed roller 15 for measuring the length of strip material which has been fed past the roller 15.
  • the axes of rotation of the rollers 13, 15 are perpendicular to the plane of the back plate 7. Thus if the plate is positionally fixed to the uprights the rollers can conveniently be mounted from the uprights. If the plate is pivotally mounted the rollers can be mounted from the plate 7.
  • the width of the chamber 2A is relatively narrow as compared with its length and depth.
  • the internal width of the chamber 2A needs only to be slightly greater than that of the strip material 3 being fed so that whilst a strip of material being fed can easily pass from the feed roller 13 to the output roller 15 with a length 3A providing the 'slack length' by drooping into the chamber 2A catenary fashion.
  • the width of the chamber is selected such that the width is not sufficient for the'slack length' easily to tangle or otherwise jam in the chamber 2A.
  • a photoelectric detection system 20 is provided for determining the position of the 'slack length' with respect to predetermined upper and lower levels 21 and 22 relative to the depth of the chamber 2A.
  • the detection system 20 includes at the upper level a photoelectric detector 23 and an associated emitter 24 suitably aligned therewith.
  • the system also includes at the lower level a detector 25 and an associated suitably aligned emitter 26.
  • Each photoelectric detector unit 23, 25 is arranged to produce a control signal which is applied to a control unit (not shown in Figures 1 and 2) associated with the winding machine 1.
  • the difference in the rate of strip material feed into the buffer unit chamber 2A and the delivery therefrom is such that the 'slack length' 3A interrupts the light path between the emitter 24 and the detector 23 at the upper level 21 and such that it does not interrupt the light path between the corresponding units 25 and 26 at the lower level 22. That is to say the detector 23 at the upper level can be regarded as being normally OFF and the detector 25 at the lower level 22 can be regarded as being normally ON.
  • the amount of 'slack length' 3A increases and when its length is such that it has effectively lowered sufficiently to pass through the above defined lower level 22 the light path between the detector 25 and the emitter will be broken whereby the detector 25 will be effectively switched off thereby changing the electric signal delivered to the control unit.
  • this signal change is a cut-off signal which is arranged to speed up the rate of the winding of the material onto a drum or the like, or if it is more convenient to slow down the rate of discharge of the material from the supply, i.e., the delivery rate to the chamber 2A.
  • the feed of the material from the chamber 2A starts to exceed the rate at which it is delivered to the chamber 2A it will be clear that the length of the strip material forming the 'slack length' will be reduced and, in consequence, the lowermost part of the'slack length' catenary will move upwards within the chamber 2A and if the imbalance of the strip material continues a point will be reached in which the lowermost level of the 'slack length' will move above the upper level 21.
  • the 'slack length' 3A will cease to interrupt the light path between the emitter 24 and the detector 23 whereby the detector 23 is effectively switched ON and will thus produce an output signal which is applied to the above mentioned control unit.
  • the output signal can be utilised either to reduce the rate of winding onto a drum or to increase the rate of material supply to the chamber, according to whichever adjustment is considered to be the most convenient.
  • FIG. 4 A winding unit for receiving the strip material after it has passed through the chamber 2A will now be briefly considered in relation to Figure 4.
  • the winding machine includes an upper shaft 27 adapted for mounting a bobbin, drum, former, spool, reel or the like 27A (not shown in Figure 4) onto which the strip material 3 is to be wound, and a lower shaft 28 adapted to mount a bobbin, drum, former, spool reel or the like and located effectively beneath the shaft 27.
  • the shaft 27 extends outwardly from the side of a housing unit 29 which is mounted upon a support frame or pedestal 30.
  • the shaft 28 is carried from bearing arrangements 31. Similarly, the shaft 27 is mounted from suitable bearing assemblies 32 provided with the housing unit 29.
  • the shafts 27 and 28 are connected to receive drive from the output shaft 33 of an electric motor 34 by way of a belt drive system 35.
  • This drive system includes a layshaft unit 36 mounted from bearings 37.
  • the layshaft unit 36 is provided with a pulley wheel 38 which mounts a drive belt 39 connecting with a pulley wheel 40 on the shaft 27.
  • the layshaft unit is provided with a pulley wheel 41A which mounts a drive belt connecting with a pulley wheel 43 on the lower shaft 28.
  • a clutch arrangement 41, 42 is provided on the layshaft unit 36 whereby drive from the shaft unit may be selectively fed from the drive motor to the upper or the lower shafts 27, 28.
  • the clutch arrangement 41 provides a tube 37A journalled on the shaft unit 36, which carries the pulley 41A and which can be selectively coupled to receive drive from the shaft 36 or to allow the shaft 36 to run freely within the tube.
  • the drive system 35 includes a pulley 35A on the shaft 36 and a belt 35B receiving drive from the motor output shaft 33.
  • the clutch arrangement 42 is of a generally similar construction.
  • Upper and lower strip material feed and guide rollers 43A and 43B are provided for guiding the strip material during the winding operation in such manner that the material is laid onto the drum or the like in regularly spaced side by side arrangement and in layers.
  • These rollers 43A and 43B are mounted from a traversing mechanism 44 which is supported from the housing unit 29.
  • the mechanism includes a traversing block having arms 46A and 46B which respectively mount the rollers 43A and 43B.
  • the block 45 is moveable lengthwise of a traversing shaft 47 connected to receive drive from the motor 34 by way of a belt drive including pulley wheels 49 and 50, and belt 48.
  • the traversing mechanism 44 incorporates means (not shown) whereby the movement of the block 45 changes, that is reverses, direction each time it completes a traversing movement of a desired amount.
  • the electromagnetic clutches 41, 42 enable disengagement of the drive for various operational purposes such as, for example, when a drum or the like is being changed after the desired amount of strip material has been wound onto the drum and is being replaced by an empty drum.
  • the provision of the clutches 41, 42 allows the changeover of the winding operation from drum to drum i.e., from a drum on one shaft to a drum on the other shaft without it being necessary to stop the winding operation. In situations where the rate of material feed is high the fast changeover between drums is very important so as to avoid excessive waste of material.
  • each shaft 27, 28 is provided with a spring loaded mandrel 60 which essentially includes four radially directed blocks 61, 62, 63 and 64 equiangularly spaced around the associated shaft 27 or 28.
  • the blocks are held in place by countersunk bolts 65 and are resiliently loaded by compression springs 66A.
  • a second set of the blocks i.e., blocks 61A, 62A, 63A and 64A can be mounted to the blocks 61-64 by using longer bolts 65.
  • the strip material When the apparatus is in use the strip material is engaged with the rollers 13 and 15 and also by way of the roller 43A or 43B of the traversing mechanism 44 and thence to a drum 27A or 28A according to which of the drums is to be used.
  • the requisite 'slack length' is formed in the chamber 2A and the end of the strip 3 is engaged with the requisite drum.
  • the motor 34 is started. It is of course assumed that material is available from the supply.
  • the position of the lowermost part of the 'slack length' is monitored by the photoelectric detection system 20 which will be producing a first control output.
  • the length detector 17 will be measuring the amount of strip material fed through the chamber 2A and will be producing a second control signal output.
  • the traversing mechanism 44 will be laying the strip material onto the drum in successive layers.
  • a further important factor arising from the contact effected between the surface 18 and the strip material edge is that the 'slack length' is not able to move sufficiently out of its intended path to lie outside the optical paths and thus give rise to spurious signals which could lead to unrequired adjustments to the winding and/or feed rates.
  • Figure 5 schematically shows in block diagram form the broad details of electric and electronic arrangements for enabling the control of the motor drive to the shafts 27 and 28 in response to the output signals from the photoelectric detection system 20.
  • the output signals from the detection system feed into an electronic decoding logic unit 51 which serves to identify which of the photoelectric detectors 23 and 25 has been caused to vary its output signal in consequence of movements of the lowermost part of the 'slack length' 3A relative to the upper and lower levels 21 and 22.
  • the decoding unit 51 produces an output signal which is fed to the motor control unit 52 which has an output signal which controls the actual operation of the motor 34.
  • the length sensor 17 produces an output which is representative of the instantaneous amount of strip material 3 that has been fed through chamber 2A.
  • a strip length required signal which is selectively established in a length amount presetting unit 53 produces an output signal characteristic of the amount of strip material that is to be wound onto a drum. This latter signal is compared with the instantaneous length signal in a comparator 54 which is effectively a counter type comparator. This comparator 54 produces a control signal which is applied to the motor control to cause the latter to stop drive to the shaft 27 or 28 by operation of the clutches as required.
  • a motor drive accelerator control 55 is provided for over-riding the control exerted by the photoelectric detection system 20, this control providing the facility that an operator of the winding installation can wind in any excess material that may accumulate during the time period required to replace a full drum or the like with a fresh drum or the like.
