Description
CROSS REFERENCE OF RELATED APPLICATION
[0001] This application claims the benefit of priority to Chinese
Patent Application No. 201410203320.7 titled "SHEET-TYPE MEDIUM
SKEW-CORRECTION DEVICE AND AUTOMATIC TELLER MACHINE", filed with
the Chinese State Intellectual Property Office on May 14, 2014, the
entire disclosure of which is incorporated herein by reference.
FIELD
[0002] This application relates to skew-correction devices, and
more particularly to a transmission device configured to align
sheet-type mediums having various sizes, such as banknotes, checks
or other similar objects, along a certain side wall.
BACKGROUND
[0003] In a deposit process of an ATM (abbreviation for the
Automatic Teller Machine), banknotes are often placed askew at a
deposit opening of the ATM by a user, thus, the banknotes are
required to be corrected by a skew-correction device before
entering into the ATM.
[0004] Thus, the skew-correction device is mainly used in an
apparatus which has a special requirement on the position of
mediums in a conveying passage. For example, in a
depositing/withdrawing apparatus, it is required to scan a magnetic
stripe of a check, and in the case that banknotes and checks with
various sizes are mixed together and deposited, sheet-type mediums
at any positions in the passage are aligned along a certain side
wall, which facilitates the recognition of the mediums
subsequently.
[0005] A conventional skew-correction device generally includes a
set of skew wheels and an adjusting wheel. An axis direction of the
set of skew wheels is at a certain angle (greater than 0 degree and
smaller than 90 degrees) with respect to a side wall, which allows
moving tracks of the mediums to be gradually close to a certain
side wall. An axis direction of the adjusting wheel is
perpendicular to the side wall, and is mounted close to the certain
side wall along which the mediums are to be aligned, which plays an
adjusting and correcting function in the skew-correcting of the
mediums. This skew-correction device may achieve a good
skew-correcting effect to hard and new mediums, but when correcting
soft mediums having been circulated in the market for a long time,
the following two issues often present. One issue is that banknote
is jammed, in which the medium having skewed towards the direction
of the skew wheels is not corrected after being conveyed by the
skew wheel assembly, and further bump the side wall of the passage
when being moved out of the skew-correction mechanism, thus causing
the banknote jamming. The other issue is that the medium is moved
out of a skew-correction track before the skew-correction is
complete, and some mediums are moved out of the skew-correction
assembly even before the positions to be corrected.
[0006] Thus, it is necessary to provide a new skew-correction
device for correcting sheet-type mediums, which allows the
sheet-type mediums to be aligned along a side of a side wall of a
passage, and more importantly, and the skew-correction device is
adapted to the correct various material mediums, various sizes, and
various skewing states, so as to overcome the defects of the
conventional technology.
SUMMARY
[0007] To address an issue that a skew-correction device for
sheet-type mediums in the conventional technology insufficiently or
excessively corrects sheet-type mediums of different materials and
with different sizes, a skew-correction device for sheet-type
mediums is provided according to the present application, which is
adapted to correct mediums of various materials, various sizes, and
various skewing states.
[0008] The skew-correction device for sheet-type mediums according
to the present application includes: an upper holding plate and a
lower holding plate for holding the following parts and forming a
conveying passage for sheet-type mediums, a front guide wheel set
at least including one front guide wheel, in which the one front
guide wheel is mounted at a front end of the upper holding plate or
a front end of the lower holding plate for guiding the mediums into
the conveying passage, a front end position detecting element
located at the front end of each of the upper holding plate and the
lower holding plate for detecting whether a medium has entered into
the conveying passage, a side edge position detecting unit
including at least two position detectors, in which the at least
two position detectors are distributed at a certain interval on
side edges of the upper holding plate and the lower holding plate,
and the at least two position detectors are arranged in a direction
parallel to the side edges, the at least two position detectors are
configured to detect whether an edge of the medium is aligned along
the side edge of the upper holding plate or the side edge of the
lower holding plate, at least one skew-correction assembly
including a belt and a pair of pulleys, in which a conveying
direction of the belt is perpendicular to the side edge of the
upper holding plate or the side edge of the lower holding plate,
and at least one conveying assembly including a pair of conveying
wheels, in which a conveying direction of the conveying wheels is
perpendicular to the conveying direction of the belt.
[0009] Preferably, the skew-correction assembly is located between
the conveying assembly and the front guide wheel set.
[0010] Optionally, two sets of skew-correction assemblies are
provided, and two sets of conveying assemblies are provided,
specifically, one set of skew-correction assembly is located
between one set of conveying assembly and the front guide wheel
set, and the other skew-correction assembly is located between the
two sets of conveying assemblies. That is to say, the
skew-correction assemblies and the conveying assemblies are
arranged alternately, and the skew-correction assemblies are closer
to the front guide wheel set, which achieves the purpose of
skew-correcting first and then conveying.
[0011] Preferably, each pulley of the skew-correction assembly is a
drum-shaped wheel, and the drum-shaped wheel is fixed to the upper
holding plate and/or the lower holding plate by a shaft.
[0012] An automatic teller machine having the skew-correction
device for sheet-type mediums is further provided according to the
present application.
[0013] In the skew-correction device for sheet-type mediums
according to the present application, the sheet-type medium is
guided into the medium conveying passage by the front guide wheel
set, and when the font end position detecting element has detected
that a medium has entered into the conveying passage, and the
skew-correction assembly starts to operate, and the belt conveys
the medium to a position close to a side edge of each of the upper
holding plate and the lower holding plate. The side edge position
detecting unit arranged at the side edge includes at least two
position detectors, and the two position detectors are spaced apart
a certain distance, thus in the case that each of the two position
detectors has detected the medium, it is proved that the medium is
not skew anymore, and then the conveying assembly is started to
convey the sheet-type medium passing through the skew-correction
device, which achieves the purpose of skew-correction. In the
present application, the skew-correction assembly and the conveying
assembly with conveying directions perpendicular to each other are
employed to transmit the medium, and the side edge position
detecting unit is employed to detect the edge of the medium, and
when the two position detectors both have detected the medium, that
is, the skew-correction is completed, the conveying assembly is
started then to convey the medium passing through the
skew-correction device, avoiding an issue that a medium is moved
out of the skew-correction track before the skew-correction of
which finishes. In addition, the conveying assembly is started
immediately after both of the two position detectors have detected
the medium, thus, no issue of excessively skew-correction occurs,
and the banknote jamming is avoided.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solutions according to the present application
are described in detail hereinafter in conjunction with the
drawings in the embodiments of the present application. Apparently,
the embodiments described are only a part of the embodiments of the
present application, rather than all embodiments. Based on the
embodiments in the present application, all of other embodiments,
made by the person skilled in the art without any creative efforts,
fall into the scope of the present application.
[0017] Reference is made to FIGS. 1 and 2. A skew-correction device
for sheet-type mediums according to this embodiment includes an
upper holding plate 11 and a lower holding plate 12. The upper
holding plate 11 and the lower holding plate 12 are configured to
support the following parts and form a conveying passage for
sheet-type mediums. As shown in FIG. 1, a pair of front guide
wheels 21 is mounted at a front end of the upper holding plate 11,
and correspondingly, a pair of conveying wheels 22 in cooperation
with the front guide wheels 21 is mounted at a front end of the
lower holding plate 12. The pair of front guide wheels 21 is
cooperated with the pair of conveying wheels 22 to form a front
guide wheel set. The front guide wheel set is configured to guide
the mediums into the conveying passage constructed by the upper
holding plate 11 and the lower holding plate 12. The positions of
the conveying wheels 22 and the front guide wheels 21 can be
exchanged with each other up and down. That is to say, the front
guide wheels 21 may also be mounted at the front end of the lower
holding plate 12.
[0018] A front end position detecting element is further provided
at a front end of each of the upper holding plate 11 and the lower
holding plate 12. The front end position detecting element includes
two position detectors 81 and 82 located to be spaced apart by a
certain distance for detecting whether a medium has been entered
into the conveying passage. The skew-correction device for
sheet-type mediums according to this embodiment especially further
includes a side edge position detecting unit, which includes at
least two position detectors 91 and 92. The at least two position
detectors 91 and 92 are distributed at a certain interval on same
side edges of the upper holding plate 11 and the lower holding
plate 12, and the at least two position detectors 91 and 92 are
located in a direction parallel to the side edge of the upper
holding plate 11 or the lower holding plate 12. The at least two
position detectors 91 and 92 are configured to detect whether an
edge of the medium is aligned along the side edge of the upper
holding plate 11 or the lower holding plate 12. That is to say, in
the case that the medium is detected by each of the two position
detectors 91 and 92, the edge of the medium has aligned along the
side edge of the upper holding plate 11 or the lower holding plate
12, and the medium is considered to have been corrected.
[0019] Further and necessarily, the skew-correction device for
sheet-type mediums according to this embodiment at least includes a
skew-correction assembly, and the skew-correction assembly includes
a belt 51 and a pair of pulleys 41 mounted in the upper holding
plate 11 and a belt 52 and a pair of pulleys 42 mounted in the
lower holding plate 12. The belt 51 is rotated about the pair of
pulleys 41, and the belt 52 is rotated about the pair of pulleys
42. The conveying direction of the belt 51 and the belt 52 are
perpendicular to the side edge of the upper holding plate 11 or the
lower holding plate 12. Thus, the belt 51 and the belt 52 cooperate
to clamp and convey the sheet-type mediums to move the sheet-type
mediums towards the side edges of the upper holding plate 11 and
the lower holding plate 12 where the side edge position detecting
unit is mounted, which allows the edges of the sheet-type mediums
to be aligned along the side edges, and achieves the purpose of
skew-correction. As shown in FIGS. 1 and 2, the pulleys 41 and 42
of the skew-correction assembly according to this embodiment are
drum-shaped wheels, and the drum-shaped wheels 41 and 42 are
mounted to the upper holding plate 11 and/or the lower holding
plate 12 via shafts 31 and 32.
[0020] Necessarily, the skew-correction device for sheet-type
mediums according to this embodiment includes at least one
conveying assembly. As shown in FIGS. 1 and 2, the conveying
assembly includes two pairs of conveying wheels 71 and 72
distributed in parallel. The conveying wheels 71 are mounted to the
upper holding plate 11, and the conveying wheels 72 are mounted to
the lower holding plate 12. The conveying wheels 71 is cooperated
with the conveying wheels 72, and the conveying direction of the
conveying wheels 71 and 72 are perpendicular to the conveying
direction of the belts 51 and 52. The function of a conveying wheel
set is to continue to convey forward the sheet-type mediums which
have been corrected. Thus, the skew-correction assembly is located
between the conveying assembly and the front guide wheel set. That
is to say, the sheet-type mediums being guided into the conveying
passage by the front guide wheel set are first conveyed to the side
edge of the upper holding plate 11 and/or the lower holding plate
12 by a skew-correction wheel set, which allow the edges of the
sheet-type mediums to be aligned along the side edge of the upper
holding plate 11 and/or the lower holding plate 12 and are not skew
anymore and then are continually conveyed by a conveying wheel set
into the conveying passage.
[0021] In this embodiment, two sets of skew-correction assemblies
are provided, that is, two sets of belt pulley assemblies (each set
of belt pulley assembly includes a belt 51 and two drum-shaped
wheels 41) in the upper holding plate 11, and two sets of belt
pulley assemblies (each set of belt pulley assembly includes a belt
52 and two drum-shaped wheels 42) in the lower holding plate 12 in
cooperation with the two sets of belt pulley assemblies in the
upper holding plate 11. Also two sets of conveying assemblies are
provided, that is, four conveying wheels 71 in the upper holding
plate 11 and four conveying wheels 72 in the lower holding plate 12
cooperated with the four conveying wheels 71 in the upper holding
plate 11. Specifically, two pairs of conveying wheels distributed
in parallel are one set. The set of skew-correction assembly closer
to the front guide wheels 21 is located between a set of conveying
assembly and the front guide wheel set, and the other set of
skew-correction assembly is located between the two sets of
conveying assemblies. That is to say, the skew-correction
assemblies and the conveying assemblies are arranged alternately,
and the skew-correction assemblies are closer to the front guide
wheel set, which achieves the purpose of skew-correcting first and
then conveying.
[0022] In the skew-correction device for sheet-type mediums
according to this embodiment, the sheet-type medium is guided into
the medium conveying passage by the front guide wheel set, and when
the font end position detecting element has detected that a medium
has entered into the conveying passage, the information is fed back
to the controller, and an instruction is sent by the controller and
thus the skew-correction assembly starts to operate, and the belt
conveys the medium to a position close to the side edges of the
upper holding plate and the lower holding plate. The side edge
position detecting unit located at the side edges includes at least
two position detectors, which are spaced apart a certain distance
and arranged in a direction parallel to the side edges, thus in the
case that both of the two position detectors have detected the
medium (are covered by the medium), it is indicated that the medium
is not skew anymore, and a signal is fed back by the position
detectors to the controller, and at this time, the controller
starts up the conveying assembly, and the conveying assembly
continues to convey the sheet-type medium forward to the
skew-correction device, so as to achieve the purpose of skew
correction. In the present application, the skew-correction
assembly and the conveying assembly with conveying directions
perpendicular to each other are employed to deliver the medium, and
the side edge position detecting unit is employed to detect the
edge of the medium. After the two position detectors have both
detected the medium, that is, after the skew-correction is
completed, the conveying assembly is started up to convey the
medium passing through the skew-correction device, which avoids the
issue that a medium is moved out of the skew-correction track
before the skew-correction is completed. In addition, the conveying
assembly is started up immediately after both of the two position
detectors have detected the medium, thus, excessively
skew-correction and the banknote jamming are avoided.
[0023] An automatic teller machine is further provided according to
an embodiment of the present application, and the automatic teller
machine has the skew-correction device for sheet-type mediums
according to the above embodiments.
[0024] The above are only preferable embodiments of the present
application and are not intended to limit the protection scope of
the present application. Any equivalent variations made based on
the specification and drawings of the present application should be
deemed to fall into the protection scope of the present
application.
