- FIGS. 3A-3D are detailed diagrams of an example of an improved stacker wheel 300 for use in a media dispenser, for example as part of an automated teller machine (ATM).
- the improved stacker wheel 300 is capable of handling many different types of media including, but not limited to currency notes, tickets (e.g. train tickets), credit/debit cards and mobile phone top-up cards.
- the wheel 300 has a central web-like hub 301 comprising a plurality of spokes 302 attached to an axle 303 . Attached to the spokes 302 of the web-like hub 301 are a plurality of curved tines 304 (six tines in the example shown in FIGS. 3A-3D ). Although the hub is shown in FIGS. 3A-3D as being web-like, it could alternatively be disk-like (i.e. a solid planar disk rather than discrete spokes). In use the stacker wheel 300 rotates about an axis of rotation 305 central to the axle 303 .
- the axle 303 is substantially cylindrical in shape and comprises a first portion 303 a extending parallel to the axis of rotation 305 from one side of the stacker wheel, and a second portion 303 b extending parallel to the axis of rotation 305 from the opposite side of the stacker wheel.
- the structure of the axle is described in more detail below with reference to FIGS. 4, 5A , 5 B, 6 A and 6 B.
- the width of a tine is measured in a direction parallel to the axis of rotation 305 of the stacker wheel.
- a width of 7.0 mm is considered an optimum width because the wide surfaces of the tine reduce the risk of damaging the media by contact with narrow edges and/or surfaces, whilst also providing a structure which is robust and can be easily manufactured, (as w increases, it becomes harder to remove the structure from a mould).
- each tine, t decreases towards the tip 306 of the tine, i.e. the thickness decreases with increasing distance from the central web-like hub 301 .
- the thickness of each tine, t is measured radially to the axis of rotation 305 of the stacker wheel.
- the gaps or compartments 313 formed between adjacent tines increase in thickness with increasing distance from the central hub 301 .
- the tines are flexible. The combination of the flexibility of the tines and the increasing thickness of the compartments 313 allows media inserted into a compartment to flatten itself out between the tines and find its own level. This minimizes the stress on the media and enables the stacker wheel to hold media gently with minimal deformation.
- Each tine 304 is curved over at least a portion of its length and comprises a spiral portion 304 a adjacent to the hub 301 which is connected at one end to a spoke 302 .
- At the other end of the spiral portion 304 a is an optional straight portion 304 b which extends from the spiral portion 304 a to the tip 306 of the tine.
- the spiral portion 304 a extends from a spoke 302 to the tip 306 .
- Example values are shown in the table below: Inner Spiral Radius, Outer Spiral Radius, Angle, ⁇ R1 (mm) R2 (mm) 10° 41.083 43.208 20° 10.167 42.417 30° 39.250 41.625 40° 38.333 40.833 50° 37.417 40.042 60° 36.500 39.250 70° 35.583 38.458 80° 34.667 37.667 90° 33.750 36.875 10 31.917 36.083 11 — 35.292 12 — 34.500 13 — 33.708 14 — 32.917 15 — 32.125 16 — 31.333 17 — 30.542
- the outer surface 308 of the tine extends through a much larger angle, (i.e. a larger range of values of ⁇ ), than the inner surface 307 of the tine.
- the values of the constants in equations 1 and 2 (K1, K2) and the maximum radii (42, 44 mm respectively) may be varied according to the overall size of the stacker wheel and the type of media to be carried in the stacker wheel.
- the stacker wheel 300 in the example shown has a diameter of 95.0 mm and has been designed to be suitable for all media types. This diameter is considered to be of an optimum size because whilst a larger diameter wheel has an advantage that media is deformed less, it also has the disadvantage that the overall size of the dispenser unit is increased.
- the inner and outer surfaces of the tine 307 , 308 are not curved but planar.
- the outer surface of the tine 308 in the straight portion is tangential to the curve of the outer surface at the end of the spiral portion 304 a (at point 309 ).
- the inner surface of the tine 307 in the straight portion is not parallel to the outer surface 308 but instead is angled with respect to the outer surface such that the thickness of the tine in the straight portion 304 b continues to taper towards the tip 306 .
- the length of the straight portion 304 b in the example shown is 15.5 mm.
- the length of the straight portion, for a 95.0 mm diameter stacker wheel should preferably be less than 20.0 mm. This is because a longer straight portion interferes with the media being inserted into the compartment 313 which is formed by that tine and the adjacent tine in a counter-clockwise direction and can cause the media to be damaged or not enter the compartment correctly.
- the tip of the tine 306 is angled such that the angled face 310 traces a circle (shown by a dotted line 311 in FIG. 3C ) as the stacker wheel rotates. In operation, the stacker wheel in the orientation shown in FIGS. 3A, 3C and 3 D would be rotated in a clockwise direction.
- the end of the tip 306 is not a sharp point but rounded. This is for ease of manufacture and to minimize damage to media should it be inadvertently struck by the tip of a tine.
- the tip 306 of the tine may be straight rather than angled (e.g. the tip may be formed perpendicular to one of the surfaces 307 , 308 of the tine).
- the stacker wheel 300 shown in FIGS. 3A-3D has 6 tines. This is by way of example only and the wheel could have more tines or fewer tines. Six tines is however, considered an optimum number for a stacker wheel of this size. Larger numbers of tines result in narrower openings, g, to the compartments 313 between tines, making it more difficult to correctly feed media into the stacker wheel, whilst a smaller number of tines requires the speed of rotation of the wheel to be increased for a fixed delivery rate of notes to the stacker wheel (e.g. 1 note every 200 ms).
- the tines are shown in FIGS. 3A-3D as being evenly spaced (e.g. one starts every 60°), however, they could be irregularly spaced such that some compartments between adjacent tines are larger than other compartments and therefore are more suitable for handling very thick and/or inflexible media.
- the sides of the tines may be provided with grooves 312 .
- Such grooves may be provided in the thicker parts of the tines, as shown in FIGS. 3A-3D .
- Grooves may, in addition or alternatively, be provided in other parts of the stacker wheel such as the spokes and the axle. These grooves are beneficial as they reduce the cross-section of the material which makes the wheel easier to manufacture by molding.
- the stacker wheel is arranged such that a plurality of identical stacker wheels 300 can be connected together in a modular manner with a common axis of rotation 305 , as shown in FIG. 4 .
- FIG. 4 shows 3 stacker wheels being connected together by way of example only. However, more commonly 4 wheels are connected together to form a stacker wheel assembly.
- the first portion 303 a of the axle has an inner diameter d 1 (see FIG. 3A ) and an outer diameter d 2 (see FIG. 3B ), whilst the second portion 303 b has an inner diameter d 3 (not shown in the figures) and an outer diameter d 4 (see FIG. 3B ).
- the second portion 303 b of a first stacker wheel can be inserted into the first portion 303 a of a second stacker wheel and therefore: d4 ⁇ d1 (Equation 4)
- the first portion 303 a of a stacker wheel 300 has two pairs of holes 317 a , 317 b , as shown in FIGS. 5A and 5B .
- FIG. 5A is an enlarged view of a part of FIG. 3C and
- FIG. 5B is an enlarged view of a part of FIG. 3A .
- n 6 and therefore the angle between the tines is 600.
- the second portion 303 b of a stacker wheel has a pair of lugs 315 mounted on resilient members 316 as shown in FIGS. 6A and 6B .
- FIG. 6A is an enlarged view of a part of FIG. 3B and FIG. 6B shows the second portion 303 b rotated by 90° about the axis of rotation 305 .
- the members 316 are resilient due to the slots 318 in the second portion 303 b of the axle which define the width and length of the members 316 .
- a first and a second stacker wheel 300 can therefore be connected together in one of two orientations.
- the lugs 315 on a first stacker wheel are located in the first pair of holes 317 a in a second stacker wheel.
- the lugs 315 on the first stacker wheel are located in the second pair of holes 317 b in the second stacker wheel.
- the stacker wheel 300 has two pairs of holes by way of example only.
- a stacker wheel could have one pair of holes, giving only a single possible orientation and spacing of stacker wheels when formed into a stacker wheel assembly.
- a stacker wheel could be provided with more than two pairs of holes to provide a larger number of options for spacing and/or rotational alignment of stacker wheels once connected together.
- a stacker wheel could be provided with more than two lugs mounted on resilient members, and a corresponding increase in numbers of holes, e.g. three lugs on the second portion of the axle 303 b and then corresponding numbers of holes on the first portion 303 a depending on the numbers of different connection positions.
- connecting lugs 315 are mounted on resilient members 316 , it may be possible to separate the stacker wheels once connected and reconnect them as required. This has benefits should one or more wheels of a stacker wheel assembly require replacement.
- the lugs 315 and holes 317 provide a dual function as they both serve to align two stacker wheels and to connect them together. Lugs and holes are only one example of an aligning and connecting mechanism that can be used.
- the inside of the first portion 303 a of the axle could be provided with a series of grooves and ridges running parallel to the axis of rotation.
- the outside of the second portion 303 b of the axle could be provided with a corresponding series of grooves and ridges such that the ridges on the second portion 303 b fit into the grooves inside a first portion 303 a of a second stacker wheel. If the fit between parts 303 a and 303 b is sufficiently tight, the ridges and grooves could provide both alignment and connection functions or alternatively a separate connection mechanism could be provided.
- the external cross-section of the second portion 303 b could be non-circular (e.g. hexagonal, elliptical etc) and the internal cross-section of the first portion 303 a could be the same non-circular shape. Therefore the second portion 303 b of a first stacker wheel could still fit within a first portion 303 a of a second stacker wheel in such a manner that they are aligned.
- a separate connection mechanism e.g. hole and locking pin
- a stacker wheel could be provided with identical first and second portions of the axle and a special connecting element used to join and align stacker wheels to form a stacker wheel assembly.
- FIG. 4 and the above discussion relates to connecting identical stacker wheels together to form a stacker wheel assembly
- stacker wheels having compatible connection and alignment features but non-identical tine arrangement could be connected together. This may be beneficial in a large dispensing unit with two (or more) feed paths handling different media and where the stacker wheel assembly has two sections, one for receiving media from the first feed path and one for handling media received from the second feed path.
- the stacker wheel 300 shown in FIGS. 3-6 is integrally formed from a plastic material by molding or other suitable manufacturing process.
- the stacker wheel could alternatively be cast in metal or formed from any other suitable material.

Abstract
The invention relates to a stacker wheel for handling media, suitable for use in a media dispenser within an automated teller machine. The stacker wheel comprises a plurality of curved tines attached to a central hub. Each curved tine has a thickness that reduces with increased distance from the central hub over substantially the whole length of the tine, such that the spacing between adjacent tines increases with increased distance from the central hub over substantially the whole length of the tine.
Description
- The present invention relates to an improved stacker wheel. It is particularly related to, but in no way limited to, stacker wheels for handling media in an automated teller machine (ATM).
- Stacker (or stacking) wheels are commonly used in automated teller machines (ATMs) to stack multiple currency notes prior to dispensing the stack of notes to a user of the ATM. The operation of a stacker wheel can be described with reference to
FIG. 1 which shows a schematic side elevation view of acash dispenser unit 73 of an ATM. Thecash dispenser unit 73 includes astacker wheel assembly 75. Thestacker wheel assembly 75 comprises a plurality ofstacker wheels 76 spaced apart in a parallel relationship along ashaft 77, eachstacker wheel 76 having a plurality ofcurved tines 78. - The
cash dispenser unit 73 holds a number ofcurrency cassettes 89 each holding a stack ofcurrency notes 68. When one or more notes are to be dispensed from a particular cassette, thepick mechanism 74 associated with the cassette draws a note from the cassette such that its leading edge is gripped betweendrive rollers 90. The note is then fed along thefeed path 72 byfurther drive rollers 92, through aretard mechanism 10 to thestacker wheel assembly 75. In operation, thestacker wheel assembly 75 rotates continuously in a counter-clockwise direction (for the arrangement shown inFIG. 1 ) and the note is fed into acompartment 81 formed betweenadjacent tines 78. If more than one note is to be dispensed, each note is fed into asuccessive compartment 81 as thestacker wheel assembly 75 rotates. Having completed half a rotation, the note is removed from thestacker wheel assembly 75 byfingers 94 of astripper plate assembly 96 pivotally mounted on ashaft 98. Once removed from the stacker wheel, the note is placed on abelt 100 resting against thestripper plate assembly 96 and any subsequent notes which are to be dispensed simultaneously with the first note are placed on top of the first note to form abundle 68′. When the required amount of notes (which may be just one note) have been assembled into thebundle 68′, a pair of belts 102 (only one of which is shown inFIG. 1 ) is rotated on ashaft 104 such that thebundle 68′ is trapped between thebelts belts note exit slot 110 in thehousing 112 of thecash dispenser unit 73 to a position where thebundle 68′ can be collected by the user of the ATM. If a multiple feeding is detected in the course of stacking the bundle ofnotes 68′ or one or more of the notes is rejected for any reason, the bundle is not fed to thenote exit slot 110. Instead thestripper plate assembly 96 is pivoted into a position as shown by thedashed outline 96′ and thebelts bundle 68′ into areject note container 114 via anopening 116. -

FIGS. 5A and 5B are detailed diagrams of a first portion of the axle of the stacker wheel shown inFIGS. 3A-3D ; and -
FIGS. 6A and 6B are detailed diagrams of a second portion of the axle of the stacker wheel shown inFIGS. 3A-3D . - Common reference numerals are used throughout the figures to indicate similar features.
-
FIGS. 3A-3D are detailed diagrams of an example of animproved stacker wheel 300 for use in a media dispenser, for example as part of an automated teller machine (ATM). Theimproved stacker wheel 300 is capable of handling many different types of media including, but not limited to currency notes, tickets (e.g. train tickets), credit/debit cards and mobile phone top-up cards. - The
wheel 300 has a central web-like hub 301 comprising a plurality ofspokes 302 attached to anaxle 303. Attached to thespokes 302 of the web-like hub 301 are a plurality of curved tines 304 (six tines in the example shown inFIGS. 3A-3D ). Although the hub is shown inFIGS. 3A-3D as being web-like, it could alternatively be disk-like (i.e. a solid planar disk rather than discrete spokes). In use thestacker wheel 300 rotates about an axis ofrotation 305 central to theaxle 303. - The
axle 303 is substantially cylindrical in shape and comprises afirst portion 303 a extending parallel to the axis ofrotation 305 from one side of the stacker wheel, and asecond portion 303 b extending parallel to the axis ofrotation 305 from the opposite side of the stacker wheel. The structure of the axle is described in more detail below with reference toFIGS. 4, 5A , 5B, 6A and 6B. - Each
tine 304 has a substantially uniform width, w, as shown inFIGS. 3A and 3B and in the example shown w=7.0 mm. The width of a tine is measured in a direction parallel to the axis ofrotation 305 of the stacker wheel. A width of 7.0 mm is considered an optimum width because the wide surfaces of the tine reduce the risk of damaging the media by contact with narrow edges and/or surfaces, whilst also providing a structure which is robust and can be easily manufactured, (as w increases, it becomes harder to remove the structure from a mould). - The thickness of each tine, t, (see
FIG. 3D ) decreases towards thetip 306 of the tine, i.e. the thickness decreases with increasing distance from the central web-like hub 301. The thickness of each tine, t, is measured radially to the axis ofrotation 305 of the stacker wheel. As a result of the tapering thickness of each tine, the gaps orcompartments 313 formed between adjacent tines increase in thickness with increasing distance from thecentral hub 301. As a further result of the tapering thickness of each tine, the tines are flexible. The combination of the flexibility of the tines and the increasing thickness of thecompartments 313 allows media inserted into a compartment to flatten itself out between the tines and find its own level. This minimizes the stress on the media and enables the stacker wheel to hold media gently with minimal deformation. - Each
tine 304 is curved over at least a portion of its length and comprises aspiral portion 304 a adjacent to thehub 301 which is connected at one end to aspoke 302. At the other end of thespiral portion 304 a is an optionalstraight portion 304 b which extends from thespiral portion 304 a to thetip 306 of the tine. In an embodiment in which the tines do not comprise a straight portion, thespiral portion 304 a extends from aspoke 302 to thetip 306. - In the
spiral portion 304 a, theinner surface 307 and theouter surface 308 of the tine are curved and follow uniform spirals. In the example shown, these spirals are defined by the following equations:
Inner spiral formula: R1=42−K1θ (Equation 1)
Outer spiral formula: R2=44−K2θ (Equation 2) - where:
-
- K1=0.0916667,
- K2=0.0791667,
- R1, R2 are measured in millimeters, and
- θ is the angle, measured about the axis of rotation, from the
point 309 at the end of the spiral portion distant from the hub (seeFIG. 3D ).
- θ is the angle, measured about the axis of rotation, from the
- And therefore, as shown in
FIG. 3D , the thickness of a tine is given by:
t=R2−R1 (Equation 3) - Example values are shown in the table below:
Inner Spiral Radius, Outer Spiral Radius, Angle, θ R1 (mm) R2 (mm) 10° 41.083 43.208 20° 10.167 42.417 30° 39.250 41.625 40° 38.333 40.833 50° 37.417 40.042 60° 36.500 39.250 70° 35.583 38.458 80° 34.667 37.667 90° 33.750 36.875 10 31.917 36.083 11 — 35.292 12 — 34.500 13 — 33.708 14 — 32.917 15 — 32.125 16 — 31.333 17 — 30.542 - As shown in
FIG. 3C and detailed in the table above, due to the arrangement by which atine 304 is connected to aspoke 302, theouter surface 308 of the tine extends through a much larger angle, (i.e. a larger range of values of θ), than theinner surface 307 of the tine. - The values of the constants in equations 1 and 2 (K1, K2) and the maximum radii (42, 44 mm respectively) may be varied according to the overall size of the stacker wheel and the type of media to be carried in the stacker wheel. The
stacker wheel 300 in the example shown has a diameter of 95.0 mm and has been designed to be suitable for all media types. This diameter is considered to be of an optimum size because whilst a larger diameter wheel has an advantage that media is deformed less, it also has the disadvantage that the overall size of the dispenser unit is increased. - In the
straight portion 304 b, the inner and outer surfaces of thetine tine 308 in the straight portion is tangential to the curve of the outer surface at the end of thespiral portion 304 a (at point 309). The inner surface of thetine 307 in the straight portion is not parallel to theouter surface 308 but instead is angled with respect to the outer surface such that the thickness of the tine in thestraight portion 304 b continues to taper towards thetip 306. - The length of the
straight portion 304 b in the example shown is 15.5 mm. The length of the straight portion, for a 95.0 mm diameter stacker wheel should preferably be less than 20.0 mm. This is because a longer straight portion interferes with the media being inserted into thecompartment 313 which is formed by that tine and the adjacent tine in a counter-clockwise direction and can cause the media to be damaged or not enter the compartment correctly. - The tip of the
tine 306 is angled such that theangled face 310 traces a circle (shown by a dottedline 311 inFIG. 3C ) as the stacker wheel rotates. In operation, the stacker wheel in the orientation shown inFIGS. 3A, 3C and 3D would be rotated in a clockwise direction. The end of thetip 306 is not a sharp point but rounded. This is for ease of manufacture and to minimize damage to media should it be inadvertently struck by the tip of a tine. - In another embodiment, the
tip 306 of the tine may be straight rather than angled (e.g. the tip may be formed perpendicular to one of thesurfaces - The
stacker wheel 300 shown inFIGS. 3A-3D has 6 tines. This is by way of example only and the wheel could have more tines or fewer tines. Six tines is however, considered an optimum number for a stacker wheel of this size. Larger numbers of tines result in narrower openings, g, to thecompartments 313 between tines, making it more difficult to correctly feed media into the stacker wheel, whilst a smaller number of tines requires the speed of rotation of the wheel to be increased for a fixed delivery rate of notes to the stacker wheel (e.g. 1 note every 200 ms). - The tines are shown in
FIGS. 3A-3D as being evenly spaced (e.g. one starts every 60°), however, they could be irregularly spaced such that some compartments between adjacent tines are larger than other compartments and therefore are more suitable for handling very thick and/or inflexible media. - Although, as described above, the tines have substantially uniform width, w, the sides of the tines may be provided with
grooves 312. Such grooves may be provided in the thicker parts of the tines, as shown inFIGS. 3A-3D . Grooves may, in addition or alternatively, be provided in other parts of the stacker wheel such as the spokes and the axle. These grooves are beneficial as they reduce the cross-section of the material which makes the wheel easier to manufacture by molding. - The stacker wheel is arranged such that a plurality of
identical stacker wheels 300 can be connected together in a modular manner with a common axis ofrotation 305, as shown inFIG. 4 .FIG. 4 shows 3 stacker wheels being connected together by way of example only. However, more commonly 4 wheels are connected together to form a stacker wheel assembly. - The
first portion 303 a of the axle has an inner diameter d1 (seeFIG. 3A ) and an outer diameter d2 (seeFIG. 3B ), whilst thesecond portion 303 b has an inner diameter d3 (not shown in the figures) and an outer diameter d4 (seeFIG. 3B ). Thesecond portion 303 b of a first stacker wheel can be inserted into thefirst portion 303 a of a second stacker wheel and therefore:
d4≧d1 (Equation 4) - Once the
second portion 303 b of a first stacker wheel has been inserted into thefirst portion 303 a of a second stacker wheel, the two are aligned and connected together by means ofco-operating lugs 315 and holes 317, as shown in more detail inFIGS. 5A, 5B , 6A and 6B. - The
first portion 303 a of astacker wheel 300 has two pairs ofholes FIGS. 5A and 5B .FIG. 5A is an enlarged view of a part ofFIG. 3C andFIG. 5B is an enlarged view of a part ofFIG. 3A . Each pair of holes comprises two holes arranged opposite each other (seeFIG. 5A ) and the second pair ofholes 317 b is arranged at an angle α to the first pair of holes (in this example α=60°) and is closer to the spokes of the wheel (seeFIG. 5B ). The value of α is preferably a multiple of the angle between the tines, where for uniformly spaced tines, the angle between the tines is given by:
Angle between the tines=360°/n (Equation 5) - where n=number of tines
- In the example shown, n=6 and therefore the angle between the tines is 600.
- The
second portion 303 b of a stacker wheel has a pair oflugs 315 mounted onresilient members 316 as shown inFIGS. 6A and 6B .FIG. 6A is an enlarged view of a part ofFIG. 3B andFIG. 6B shows thesecond portion 303 b rotated by 90° about the axis ofrotation 305. Themembers 316 are resilient due to theslots 318 in thesecond portion 303 b of the axle which define the width and length of themembers 316. - A first and a
second stacker wheel 300 can therefore be connected together in one of two orientations. In a first orientation, thelugs 315 on a first stacker wheel are located in the first pair ofholes 317 a in a second stacker wheel. In a second orientation, thelugs 315 on the first stacker wheel are located in the second pair ofholes 317 b in the second stacker wheel. In the first orientation there is a larger spacing between stacker wheels than in the second orientation. - The
stacker wheel 300 has two pairs of holes by way of example only. In another embodiment, a stacker wheel could have one pair of holes, giving only a single possible orientation and spacing of stacker wheels when formed into a stacker wheel assembly. Alternatively, a stacker wheel could be provided with more than two pairs of holes to provide a larger number of options for spacing and/or rotational alignment of stacker wheels once connected together. In another example, a stacker wheel could be provided with more than two lugs mounted on resilient members, and a corresponding increase in numbers of holes, e.g. three lugs on the second portion of theaxle 303 b and then corresponding numbers of holes on thefirst portion 303 a depending on the numbers of different connection positions. - As the connecting
lugs 315 are mounted onresilient members 316, it may be possible to separate the stacker wheels once connected and reconnect them as required. This has benefits should one or more wheels of a stacker wheel assembly require replacement. - As described above the
lugs 315 and holes 317 provide a dual function as they both serve to align two stacker wheels and to connect them together. Lugs and holes are only one example of an aligning and connecting mechanism that can be used. In another embodiment, the inside of thefirst portion 303 a of the axle could be provided with a series of grooves and ridges running parallel to the axis of rotation. The outside of thesecond portion 303 b of the axle could be provided with a corresponding series of grooves and ridges such that the ridges on thesecond portion 303 b fit into the grooves inside afirst portion 303 a of a second stacker wheel. If the fit betweenparts - As described above, in an alternative embodiment separate features could be used for aligning stacker wheels and connecting the stacker wheels together. For example the external cross-section of the
second portion 303 b could be non-circular (e.g. hexagonal, elliptical etc) and the internal cross-section of thefirst portion 303 a could be the same non-circular shape. Therefore thesecond portion 303 b of a first stacker wheel could still fit within afirst portion 303 a of a second stacker wheel in such a manner that they are aligned. A separate connection mechanism (e.g. hole and locking pin) could be provided. - In another embodiment, a stacker wheel could be provided with identical first and second portions of the axle and a special connecting element used to join and align stacker wheels to form a stacker wheel assembly.
- Although
FIG. 4 and the above discussion relates to connecting identical stacker wheels together to form a stacker wheel assembly, in another embodiment, stacker wheels having compatible connection and alignment features but non-identical tine arrangement could be connected together. This may be beneficial in a large dispensing unit with two (or more) feed paths handling different media and where the stacker wheel assembly has two sections, one for receiving media from the first feed path and one for handling media received from the second feed path. - The
stacker wheel 300 shown inFIGS. 3-6 is integrally formed from a plastic material by molding or other suitable manufacturing process. The stacker wheel could alternatively be cast in metal or formed from any other suitable material. - The integral formation of the
tines 304, lugs 315 and holes 317, the alignment of tines of each stacker wheel in a stacker wheel assembly is guaranteed. Furthermore, the integral molding of the axle minimizes the numbers of piece parts, makes assembly of a stacker wheel assembly both simple and quick and eliminates problems such as wear and differential thermal expansion which can be caused by material mismatch. - Any range or device value given herein may be extended or altered without losing the effect sought, as will be apparent to the skilled person.
- The steps of the methods described herein may be carried out in any suitable order, or simultaneously where appropriate.
- It will be understood that the above description of a preferred embodiment is given by way of example only and that various modifications may be made by those skilled in the art.
