Definitions

  • the invention relates to the storage of banknotes or other sheets of value, which are herein referred to simply as banknotes.
  • a banknote store comprising first and second drums with a strip wound onto both drums and arranged to support banknotes disposed in succession between windings of the strip on the first drum.
  • the strip is wound from the first drum to the second drum to expose successive supported banknotes for removal and is wound from the second drum to the first drum to enable banknotes to be deposited successively on the first drum.
  • the second drum is driven to rotate to wind the strip from the first to the second drum while the first drum may be driven to follow the second drum.
  • the first drum is driven to rotate to wind the strip from the second to the first drum while the second drum may be driven to follow the first drum.
  • the first and the second drums to be fixed for rotation relative to respective shafts which are themselves driven by one or more motors.
  • the length of strip unwound therefrom also decreases, provided the rotational speed of the drum remains constant.
  • the length of strip wound onto or unwound from a drum is dependent on the circumference of the outer winding on the drum.
  • the strip may be held firmly between the drums, by winding the strip onto one drum by rotating that drum, whilst providing some resistance to rotation of the other drum, from which the strip is being unwound. This arrangement enables the strip to be held firmly only when the drums are rotating but may not when the drums are stationary,
  • the drums are rotated at varying speeds.
  • the drum may be rotated gradually more quickly, because the length of strip being unwound from it per revolution gradually decreases.
  • the other drum which may be rotated gradually more slowly as the length of strip being wound onto it per revolution gradually increases.
  • the continuous adjustment of the rotational speeds of the drums requires relatively complicated and expensive arrangements and control of the motor or motors driving the shafts.
  • US-A-5,622,027 discloses a store for flexible planar articles having the features of the preamble of Claim 1 wherein the coupling means consist in belt drive train and wherein biasing means are provided between the belt drive train and one of the winding means so as to maintain tension all the time in the support member.
  • US-A-4,871,125 discloses a banknote store according to the preamble of Claim 1 wherein a friction gear train forms the coupling means and biasing means are provided between the coupling means and one of the winding means for maintaining tension in the support member.
  • banknote stores 10, 12, 14, 16 are shown. Such banknote stores may make up component features of a banknote receiving and dispensing machine. Since the stores are very similar, specific reference herein will be made only to store 10.
  • Store 10 comprises a first, or storage, winding means and two second, or supply, winding means.
  • the first winding means may take the form of a storage drum 18 and the second winding means may take the form of supply drums 20, 22. Other types of winding means may be used as appropriate.
  • the storage drum has wound around it a pair of strips 24, 26 which extend away from the storage drum to rollers 28, 30. The strips then separate, with one strip extending around roller 28 to supply drum 20, and the other strip 26 extending around roller 30 to supply drum 22. Between roller 28 and supply drum 20, strip 24 is guided by additional rollers 32.
  • the strips are one example of elongate support members but other examples may be used instead.
  • the storage drum 18 and the supply drums 20, 22 rotate in the directions indicated by the arrows A, the strips 24, 26 are unwound from the storage drum and onto respective supply drums 20, 22.
  • the storage drum 18 and the supply drums 20, 22 can alternatively rotate in the opposite directions so that the strips are unwound from the supply drums onto the storage drum.
  • Banknotes (60, see Figure 2) can be fed between the strips 24, 26 as they come together at rollers 28, 30, when the strips are being wound onto the storage drum 18.
  • individual banknotes can be stored in a spiral arrangement on the storage drum, in successive positions between strips 24, 26.
  • an endless belt or strip 34 and series of rollers 36 can be used to guide the banknote from one position relative to the banknote store 10 to be taken up between strips 24, 26.
  • any banknotes held thereby will be delivered to belt 34 to be guided to an appropriate position, for instance in a banknote receiving and dispensing machine.
  • a banknote introduced to such a machine may be guided to a position between rollers 28, 30 whilst strips 24, 26 are being wound onto storage drum 18 (drums rotated in opposite direction to A).
  • the banknote becomes gripped between the strips 24, 26 as they converge at rollers 28, 30, the banknote then being transported to the storage drum.
  • a motor 38 is used for driving, via a gear 40, the shafts of the rollers 28 and 30 to transport the strips 24, 26 at a constant speed in either of two opposite directions.
  • Gears 44, 46 and 50 are coupled to shafts 51 (see Figure 1) of storage drum 18 and supply drums 22 and 20, respectively, as shown schematically by lines 52 in Figure 2. These gears interengage such that they rotate together, in this case by interengaging storage drum gear 44 with first supply drum gear 46, and first supply drum gear 46 with second supply drum gear 50 via an idler gear 48. (In Figure 2, the arrangement differs slightly from Figure 1, in that the supply drums rotate in the same direction, so the idler gear 48 is provided between gears 46 and 50 to achieve this.)
  • Biasing means in the form of spiral or torsional springs 54, 56, 58 connect the shafts to the respective gears 44, 46, 50.
  • the springs allow biased relative rotational movement between each drum and its gear. In this way, strips 24, 26 wound around the drums can be held tightly at all times.
  • the springs are biased in directions which tend to cause winding of the strips onto the respective drums, which also keeps the strips under tension.
  • the use of springs or other biasing means provides a relatively compact and low cost solution.
  • a similar effect can be achieved by alternatively providing the springs between the shafts and the drums, in which case, if the shafts extend through the drums the springs may be provided between the shafts and a radially inwardly facing surface of the respective drum.
  • Figure 3 A practical arrangement is shown in Figure 3, in which like reference numbers represent like integers.
  • the store of Figure 3 is similar to those of Figures 1 and 2 except for a re-arrangement of the relative positions of the drums, rollers and gears.
  • the gear 44 for the drum 18 engages each of the gears 46 and 50 for the supply drums 22 and 20, respectively.
  • the rollers 28 and 30 are driven at a constant speed, which determines the speed at which the strips 24, 26 travel.
  • the peripheral speeds of the drums will match the speed at which the tape is fed to or from the drums. Generally speaking, this means that the drums will rotate at a different speed from their associated gears, whose relative speeds will be governed by the gear ratios. This is permitted by the contraction and expansion of the respective springs 54, 56 and 58.
  • the gear ratios are set so that, for each drum, when the drum is halfway between its empty and full state, the rotational speed of the driving gear matches the rotational speed of the drum, as determined by the speed of movement of the strips 24, 26.
  • Appropriate gear ratios can be determined from the diameters of the half-wound drums.
  • the spring for each drum has its minimum tension when the drum is half full, although this tension is still significant because the spring is pre-loaded during assembly.
  • the periphery will be relatively small so that the drum should rotate faster than the gear.
  • the speed of the strip rotates the drum relative to its associated gear, resulting in tensioning of the spring.
  • the relatively fast feeding of the strip to the drum means that the spring is allowed to relax, causing an increased peripheral speed of the drum.
  • the drum Conversely, if the drum is more than half full, the diameter of the drum including the strip wound thereon will be relatively large, and therefore the drum should rotate relatively slowly. The tension in the strip will slow down the drum relative to the driving gear, causing the spring to become gradually tighter, if the strip is being wound on the drum. If it is being unwound, the spring is able to relax, as the drum rotates relative to its associated gear, resulting in the drum rotating slower than the gear.
  • the assembly is designed so that the tensions produced by the springs change in synchronism in a balanced manner even though this may mean that the minimum tension does not necessarily occur when the respective drum is exactly half full.
  • gear ratios could be selected so that the speed of rotation of the drum matches that of the associated gear when the drum is fully wound (or fully unwound), in which case the tension in the spring will monotonically change as the drum is fully unwound (or wound).
  • One advantage of the above-described arrangement is that the speed of movement of the strips 24, 26 remains constant throughout the operation, so that the operation of the storage apparatus can be synchronised to the rest of the host machine in which it is installed, and, if desired, the same motor can be used to drive both the storage apparatus and other parts of the machine. If desired, additional means may be provided to maintain this constant, predictable speed of movement, by avoiding slippage at the rollers 28, 30 or by detecting such slippage and taking corrective action.
  • Figure 2 shows springs associated with the storage drum 18 and the supply drums 20, 22, it would be possible to use springs associated with the supply drums only or the storage drum only, although in such arrangements a constant speed of movement of the strips 24, 26 may be more difficult to achieve.
  • springs are associated with only the supply drums they would need to be sufficiently expansive to compensate for the change in speed of both the supply drums and the storage drum. It would be possible to associate a single spring with the storage drum only, if the supply drums behaved symmetrically with each other (for example, if coupled using a differential gear). Otherwise, the strips would be wound onto and unwound from the supply drums unevenly.
  • strips 24, 26 do not overlap.
  • Two strips 24 are wound around the storage drum and a first supply drum.
  • the other strip 26 is wound around the storage drum and a second supply drum.
  • the banknote 60 is supported between the strips, with strips 24, 24 on one side thereof and strip 26 on the other side thereof.
  • the arrangement could enable transferring of banknotes from one drum to another.
