Description
[0001] This application claims the benefit of priority to Chinese
Patent Application No. 201210447728.X titled "SHEET-TYPE MEDIUM
STACKING DEVICE", filed with the Chinese State Intellectual
Property Office on Nov. 9, 2012, the entire disclosure of which is
incorporated herein by reference.
TECHNICAL FIELD
[0002] The present application relates to a technique for
processing a sheet-type medium, and particularly to a device for
end-to-end stacking sheet-type medium piece by piece.
BACKGROUND
[0003] A device for identifying financial bills piece by piece is
generally required to be installed in the machine for processing
financial bills, and after being identified piece by piece, the
bills which are conveyed piece by piece are stacked to facilitate
withdrawing the bills. For example, in a conventional automatic
teller machine, multiple sheets of stacked banknotes are sorted,
conveyed and identified piece by piece, and then are stacked to be
delivered out. At present, in a sheet-type medium stacking device,
in which the medium is conveyed in a longitudinal direction, such
as a banknote stacking device, a conveyor belt fits closely to an
arc-shaped plate to convey a single sheet of banknote to a specific
location to be stacked. For example, the first sheet of banknote is
settled in the specific location, a front end of the second sheet
of banknote is superposed on a tail end of the first sheet of
banknote, and the first sheet of banknote and the second sheet of
banknote are clamped by the conveyor belt and the arc-shaped plate
to move forwards together, and the first sheet of banknote stops
moving forward when its front end reaches a predetermined blocking
member. The second sheet of banknote is driven by the conveyor belt
to overcome the frictional force between the banknotes and continue
to slide forward, and stops moving forward until it reaches the
predetermined blocking member. The third sheet of banknote and
subsequent banknotes go through the same process as the first and
second sheets of banknotes, that is, the front end of a subsequent
sheet of banknote is superposed on the tail end of a previous
banknote and the banknotes are all conveyed to the predetermined
blocking member, to be stacked. Eventually, the front ends of all
the banknotes are aligned to the predetermined movable blocking
plate, and a whole stack of banknotes are delivered to a
predetermined position for an operator.
[0004] However, in the above existing mechanism, starting from the
second sheet of banknote, each sheet of banknote goes through the
process of clinging to and rubbing against a previous sheet of
banknote. In this process, if the sheet of banknote has a slit at
an angle to the advancing direction, the subsequent banknote is apt
to be jammed at the slit, or if the sheet of banknote has a severe
fold, the sheet of banknote is apt to be folded and arched at the
fold, which may result in a banknote jam at the fold.
SUMMARY
[0005] An object of the present application is to provide a
sheet-type medium stacking device for effectively stacking
sheet-type medium having a slit or being soft and old.
[0006] The sheet-type medium stacking device includes: [0007] a
piece-by-piece sheet-type medium conveying mechanism configured to
convey a sheet-type medium piece by piece; [0008] an upper conveyor
belt configured to provide a driving force to the sheet-type medium
and arranged around a driving transmission shaft and a driven
transmission shaft which are arranged in a conveying direction of
the sheet-type medium; [0009] an arc-shaped stacking plate
configured to support the sheet-type medium, wherein an arc-shaped
surface, fitting closely to the upper conveyor belt, of the
arc-shaped stacking plate defines a conveying passage for the
sheet-type medium, a length of the conveying passage is at least
greater than a length of one sheet of the sheet-type medium in the
conveying direction, and one end of the conveying passage abuts the
piece-by-piece sheet-type medium conveying mechanism and is
slightly lower than a delivering outlet of the conveying mechanism,
and another end of the conveying passage forms a discharging outlet
for a whole stack of sheet-type medium; [0010] a movable blocking
mechanism arranged on a section of the conveying passage close to
the discharging outlet and configured to selectively block the
sheet-type medium; [0011] a sensor device arranged at a tail end of
the delivering outlet of the piece-by-piece sheet-type medium
conveying mechanism and configured to detect the arrival and
passing of a sheet of the sheet-type medium; and [0012] a control
unit configured to control the upper conveyor belt to move or stop
moving according to information feedback from the sensor device;
[0013] wherein, at least one pair of convex ribs are formed on a
section, close to the conveying mechanism, of the arc-shaped
surface of the arc-shaped stacking plate at two sides of the upper
conveyor belt, and a distance between the pair of convex ribs is
smaller than the minimum dimension of the sheet-type medium in a
direction perpendicular to the conveying direction.
[0014] Preferably, the arc-shaped stacking device includes three
sections, a section near the piece-by-piece sheet-type medium
conveying mechanism forms a rear arc-shaped plate, a section near
the discharging outlet forms a front arc-shaped plate, and a middle
section forms a reversing device.
[0015] Furthermore, a recycling conveyor belt assembly and a
discharging conveyor belt assembly are arranged below the reversing
device and the front arc-shaped plate, wherein at least a section
of the recycling conveyor belt assembly fits with a section of the
discharging conveyor belt assembly to form a recycling conveying
passage for the sheet-type medium.
[0016] Preferably, a floating pinch roller is provided on a side,
away from the arc-shaped plate, of the upper conveyor belt at a
position corresponding to the convex ribs, and is configured to
increase a conveying force of the upper conveyor belt to the
sheet-type medium.
[0017] Compared with the conventional technology, the valuable
document identification device has the following advantages.
[0018] By providing convex ribs on the arc-shaped stacking plate at
the position corresponding to two sides of the upper conveyor belt,
the sheet-type medium being clamped and conveyed forms a V shape,
which greatly increases the rigidity of the sheet-type medium, and
effectively solves the problems of blockage caused by the slit at
the tail of the sheet-type medium and blockage caused by folding
and arching of soft and old medium.

DETAILED DESCRIPTION
[0036] For further illustrating the sheet-type medium stacking
device according to the present application and clearly describing
the structure and operation process of the device, a deposit
machine used in a financial self-service equipment is described as
an example.
[0037] Reference is made to FIG. 1, which is a schematic view
showing the structure of a sheet-type medium stacking device (a
deposit machine). The deposit machine has a depositing port 101, a
sheet separating device 1, a sheet tilt correction device 2, a
sheet identifying device 3, a temporary storage device 4, a
stacking and recycling device 5 and a storage box 6. The sheet
separating device 1 separates banknotes at the depositing port 101
piece by piece and delivers the separated banknotes into the
deposit machine. The sheet tilt correction device 2 is configured
to adjust the banknotes inclined with respect to an advancing
direction and align the banknotes with a datum plane in parallel
with the advancing direction. The sheet identifying device 3 is
configured to identify the authenticity, the face value, the
obverse and reverse, and the condition of banknotes and checks and
to detect whether the sheets are conveyed abnormally, such as being
titled, overlapped or continuous, to determine whether the sheets
can be stored. The temporary storage device 4 is configured to
temporarily store banknotes or checks which are identifiable and
are determined as being conveyed normally. The stacking and
recycling device 5 is configured to stack banknotes or checks, to
deliver out returned banknotes or checks, and to recycle the
banknotes or checks that customers forget to withdraw. Conveying
mechanisms 102, 103, 104 and 105 for conveying sheet-type medium
piece by piece are provided between the above devices to convey
banknotes.
[0038] Reference is made to FIG. 2. The stacking and recycling
device 5 includes an upper conveyor belt 153 for providing a
driving force to the sheet-type medium, an arc-shaped stacking
plate for supporting the sheet-type medium, a movable blocking
mechanism 20 for selectively blocking the sheet-type medium, a
sensor device 17 and a control unit. The upper conveyor belt 153 is
arranged around a driving transmission shaft 151 and a driven
transmission shaft 156 which are arranged in a conveying direction
of the sheet-type medium. The arc-shaped stacking plate includes
three sections; the section, near the conveying mechanism for
conveying sheet-type medium piece by piece, forms a rear arc-shaped
plate 18; the section near a medium discharging outlet forms a
front arc-shaped plate 19; and the middle section forms a reversing
device 25. The upper conveyor fits closely to the arc-shaped
surface of the arc-shaped stacking plate, thereby forming a
conveying passage for the sheet-type medium. The length of the
conveying passage is at least greater than that the length of one
sheet of the sheet-type medium in the conveying direction. One end
of the conveying passage abuts the conveying mechanism 105 for
conveying sheet-type medium piece by piece and is slightly lower
than a delivering outlet of the conveying mechanism. Another end of
the conveying passage forms the discharging outlet for a whole
stack of sheet-type mediums. The movable blocking mechanism 20 is
arranged on a section of the conveying passage close to the
discharging outlet. The sensor device 17 is arranged at the tail
end of the delivering outlet of the conveying mechanism for
conveying sheet-type medium piece by piece and is configured to
detect the arrival and passing of a sheet of the sheet-type medium.
The control unit is configured to control the upper conveyor belt
153 to move or stop moving according to the information feedback
from the sensor device 17, thereby connecting the adjacent
sheet-type mediums, entering into the arc-shaped stacking device,
end to end. For facilitating discharging or recycling the whole
stack of sheet-type medium, corresponding to the three-section
design of the arc-shaped plate, a first conveyor belt assembly 15
is provided corresponding to the upper conveyor belt 153, a second
conveyor belt assembly 22 is provided corresponding to the front
arc-shaped plate 19, and a third conveyor belt assembly 23 is
provided corresponding to the reversing device 25.
[0039] Reference is made to FIG. 3 and FIG. 4. Two pairs of convex
ribs 183, 184 are formed on a section of the arc-shaped surface of
the rear arc-shaped plate 18 at two sides of the upper conveyor
belt 153. A distance between each pair of convex ribs 183, 184 is
smaller than the minimum dimension of the sheet-type medium in a
direction perpendicular to the conveying direction. Reference is
made to FIG. 5. To increase the conveying force of the upper
conveyor belt to the sheet-type medium at the position of the
convex ribs, a floating pinch roller 30 is provided on a side, away
from the arc-shaped plate 18, of the upper conveyor belt at a
position corresponding to the convex ribs 183, and is fixed at an
end of a floating plate 32 via a mandrel 31. The floating plate 32
is pivotally mounted on a mandrel 33.
[0040] Referring to FIG. 1, the specific working process of the
deposit machine is illustrated herein. When depositing, a customer
puts one or more sheets of banknotes at the depositing port 101,
and the banknotes are separated by the sheet separating device 1
piece by piece and then passes through the sheet tilt correction
device 2 and the sheet identifying device 3. The banknotes
determined to be normal and the face value of which has been
identified or the checks which are identifiable enter into the
temporary storage device 4 via a route 102. The banknotes or checks
which are unidentifiable are returned to the stacking and recycling
device 5 via a route 103 and a routine 105, and then are aligned
and stacked at the stacking unit 51, and the returned banknotes are
stacked and then delivered out after the banknotes at the
depositing port 101 are completely separated. When it is determined
that the returned banknotes or checks are not withdrawn by the
operator in a specific time, the banknotes or checks are recycled
to the recycling unit 52.
[0041] Referring to FIG. 6, the banknotes depositing and returning
process of the deposit machine is described herein. After the
banknotes are completely separated piece by piece, the banknotes
detected determined to be normal and the face value of which has
been identified are conveyed into the temporary storage device 4,
at this time, if the customer confirms depositing, the banknotes
are conveyed out of the temporary storage 4 and then conveyed into
the storage box 6 via a routine 104, thereby implementing the
banknotes depositing process. If the customer cancels depositing,
the banknotes are conveyed out of the temporary device 4 and
conveyed to the stacking and recycling device 5 via the routine
105, and then are aligned and stacked in the stacking unit 51, and
finally are stacked and then delivered out, thereby implementing
the banknotes returning process. When it is determined that the
returned banknotes are not withdrawn by the customer in a specific
time, the banknotes are recycled to the recycling unit 52.
[0042] Reference is made to FIG. 2 and FIG. 7. The banknotes are
returned via the routine 105 and are clamped between an upper
delivering conveyor belt 11 and a lower delivering conveyor belt 12
piece by piece to be conveyed to the stacking and recycling device
5. An upper guiding board 13 and a lower guiding board 14 are
arranged in the advancing direction of the discharged banknotes.
The first conveyor belt assembly 15 arranged in parallel to the
advancing direction of the banknotes is provided in front (the
rightward direction in the figures) of the upper guiding board 13.
A first sensor device 17 is arranged between the driving roller 151
and the delivering roller 16, and is configured to detect each
sheet of discharged banknote. The rear arc-shaped plate 18, the
front arc-shaped plate 19 and the reversing device 25 which have
similar curvatures are provided below the first conveyor belt
assembly 15, and a rear-end plane 181 of the rear arc-shaped plate
18 is obviously lower than the outlet (a port for discharging the
banknotes) formed between the upper delivering conveyor belt 11 and
the lower delivering conveyor belt 12. Above the front section of
the front arc-shaped plate 19, the movable blocking plate 20 is
pivotally mounted on a mandrel 152 and has two working states,
including a closed state as shown in FIG. 2 and an open state as
shown in FIG. 7. A second sensor device 21 is fixed in front of the
movable blocking plate 20 and is configured to detect the presence
of banknotes in front of the movable blocking plate 20 and above
the front arc-shaped plate 19. The adjustable second conveyor belt
assembly 22 is arranged below the front arc-shaped plate 19, and
the third conveyor belt assembly 23 is arranged at a corresponding
position at the rear end of the second conveyor belt assembly 22.
The first conveyor belt assembly 15, the second conveyor belt
assembly 22 and the third conveyor belt assembly 23 are driven by
the same power. A storage container 24 is arranged below the
recycling unit 52, and an inlet of the storage container 24 is
corresponding to a conveying port formed by a recycling floating
roller 221 of the second conveyor belt assembly 22 and a driving
roller 231 of the third conveyor belt assembly 23. The reversing
device 25 is arranged between the rear arc-shaped plate 18 and the
front arc-shaped plate 19 and above the conveying port formed by
the recycling floating roller 221 and the driving roller 231, and
is pivotally mounted on a mandrel 26, and has two working states,
including a first position as shown in FIG. 2 and a second position
as shown in FIG. 7.
[0043] Referring to FIG. 8 and FIG. 9, the first conveyor belt
assembly 15 is illustrated in detail. A first conveyor belt 153
(that is the upper conveyor belt) of the first conveyor belt
assembly 15 is arranged around the driving roller 151, a roller
154, a roller 155 and the pinch roller 156. The lower section of
the first conveyor belt 153 is tensed by the upper surfaces of the
rear arc-shaped plate 18 and the front arc-shaped plate 19. The
pinch roller 156 is fixed at the front end of the pressing plate
158 via a mandrel 157, and the pressing plate 158 is swingable
around the mandrel 152.
[0044] Referring to FIGS. 10 to 12, the second conveyor belt
assembly and the third conveyor belt assembly of the stacking and
recycling device are illustrated. Two abreast second conveyor belts
222 of the second conveyor belt assembly 22 are arranged around the
recycling floating roller 221, the second driving roller 223, a
second pinch roller 224 and a tensioning roller 225. The second
pinch roller 224 is directed to the pinch roller 156 of the first
conveyor belt assembly 15. The recycling floating roller 221 is
mounted on a recycling floating support 226 through a pair of
bearings and is swingable around a mandrel 227. A
banknote-delivering floating support 229 swingable around a mandrel
228 is mounted at a front end of the second conveyor belt assembly
22, and has two working states, including a first position as shown
in FIG. 11 and a second position as shown in FIG. 12. The swinging
of the delivering floating support 229 and the movable blocking
plate 20 are driven by the same power. The delivering floating
support 229 is provided with two rows of roller sets 230
corresponding to the second conveyor belt 222. The roller sets 230
may make the working surface of the second conveyor belt 222 higher
or lower than the upper arc-shaped surface of the front arc-shaped
plate 19 through the swinging of the delivering floating support
229. A third conveyor belt 233 of the third conveyor belt assembly
23 is arranged around a third driving roller 232 and the third
driven roller 231.
[0045] Referring to FIGS. 13 to 17, the process for realizing the
function of the stacking and recycling device is illustrated. When
the banknotes are to be returned, the movable blocking plate 20 is
in the closed state as shown in FIG. 13, to prevent the banknotes
from moving in the advancing direction of banknotes. The delivering
floating support 229 is in the first position, to make the working
surface of the upper section of the second conveyor belt 222 lower
than the upper arc-shaped surface of the front arc-shaped plate 19,
thus, when slipping along the arc-shaped plate, the banknotes will
not contact the working surface of the second conveyor belt 222.
The reversing device 25 is in the first position, to allow the
banknotes to pass along the arc-shaped surface smoothly. The first
sheet of banknote 27 is delivered out by the upper delivering
conveyor belt 11 and the lower delivering conveyor belt 12, the
front end of the banknote passes through the first sensor device 17
(an acquisition module), the sensor 17 feeds back an information to
a processing module of the control system, and the processing
module processes the information and then sends out a signal, to
start a first driving motor (an execution module) immediately or
start the first driving motor after a period of time, thereby
driving the first conveyor belt assembly 15, the second conveyor
belt assembly 22 and the third conveyor belt assembly 23 to rotate
in the direction shown in FIG. 13. The first conveyor belt assembly
15 cooperates with the rear arc-shaped plate 18 to convey the
banknote forward, the sensor 17 feeds back an information to the
processing module of the control system when the tail end of the
banknote leaves the first sensor device 17, and the processing
module processes the information and sends out a signal to stop the
first driving motor, and in this case, all of the conveyor belt
assemblies are stopped, the banknote stops at position 182 with the
tail end being exposed behind the first conveyor belt assembly 15.
The front end of the first sheet of banknote 27 reaches the first
pair of convex ribs 183 and the second pair of convex ribs 184. As
shown in FIG. 15, due to the action on the front end of the first
sheet of banknote 27 from the first conveyor belt 153, the first
pair of convex ribs 183 and the second pair of convex ribs 184, the
first sheet of banknote 27 is bent upward at two sides of the
advancing direction, thus the section, perpendicular to the
advancing direction, of the banknote forms a V shape. When the
second sheet of banknote 28 is delivered out, the front end of the
second sheet of banknote passes through the first sensor device 17,
the first sensor device 17 feeds back an information to the control
system, and the control system sends out a signal for starting the
first driving motor, to start the first driving motor immediately
or after a period of time, thereby driving the first conveyor belt
assembly, the second conveyor belt assembly and the third conveyor
belt assembly to rotate in the direction shown in FIG. 13. The
front end of the second sheet of banknote 28 is superposed on the
tail end of the first sheet of banknote 27, and the two sheets of
banknotes which are partially overlapped are conveyed forward
together by the first conveyor belt assembly 15. After the tail end
of the second sheet of banknote leaves the first sensor device 17,
the first sensor device 17 feeds back information to the control
system, and the control system stops the first driving motor, and
the second sheet of banknote stops at the position 182. The third
sheet of banknote and the subsequent banknotes are conveyed in the
same manner, in which the front end of a subsequent sheet of
banknote is superposed on the tail end of a previous sheet of
banknote. When the front end of the first sheet of banknote 27
reaches the movable blocking plate 20, the banknote is prevented
from moving forward, and slips with respect to the first conveyor
belt 153. The action force on the banknotes from the first conveyor
belt 153 is greater than the frictional force between the
banknotes, thereby making the second sheet of banknote 28 and the
first sheet of banknote 27 rub against each other to be aligned to
the movable blocking plate 20. The rubbing process is illustrated
as follow. Under the action of the first conveyor belt 153, the
first pair of convex ribs 183 and the second pair of convex ribs
184, the second sheet of banknote 28 is bent upward at two side of
the advancing direction, thereby making the section, perpendicular
to the advancing direction, of the banknote form a V shape. The two
sides of the second sheet of banknote 28 being bent upward makes
the two sides of the second sheet of banknote 28 higher than the
two sides of the first sheet of banknote 27, which intensifies the
strength of the banknotes in the advancing direction. Therefore,
when the second sheet of banknote 28 or the first sheet of banknote
27 have slits, the slits can be avoided in a certain extent. And if
the banknote is blocked at the slit, the first conveyor belt 153
can provide an enough conveying force for the second sheet of
banknote 28, to allow the second sheet of banknote 28 to cross the
slit without being folded and arched. As shown in FIG. 16, the
third sheet of banknote and the subsequent banknotes go through the
same process, and the front ends thereof are eventually aligned to
the movable blocking plate 20.
[0046] After all of the banknotes are delivered out, that is, the
banknotes have been processed, the control system sends out a
signal to control the second motor, to shift the movable blocking
plate 20 to the open state as shown in FIG. 17, thereby removing
the blockage in the advancing direction of the banknotes.
Meanwhile, the delivering floating support 229 is shifted to the
second position to make the working surface of the second conveyor
belt 222 higher than the upper arc-shaped surface of the front
arc-shaped plate 19, thus the working surface of the second
conveyor belt 222 is in contact with the banknotes. The first
driving motor is started to drive the first conveyor belt assembly,
the second conveyor belt assembly and the third conveyor belt
assembly to rotate in the direction shown in FIG. 17. The banknotes
are clamped between the first conveyor belt assembly 15 and the
second conveyor belt assembly 22 to be delivered out, and the
pressing plate 158 may automatically adjust the gap between the
pinch roller 156 and the second pinch roller 224 according to the
total thickness of the banknotes. According to the time counting of
the controlling program, the transmission structure stops the
conveyor belts when the banknotes are delivered out for a certain
distance, and the tail ends of the banknotes are clamped between
the pinch roller 156 and the second pinch roller 224, thereby
accomplishing the delivering process. In the case that the whole
stack of the delivered banknotes haven't been withdrawn by the
operator timely, the movable blocking plate 20 and the reversing
device 25 of the stacking and recycling device are shifted to the
position as shown in FIG. 7, the control system controls the first
conveyor belt assembly, the second conveyor belt assembly and the
third conveyor belt assembly to rotate in the reversed direction,
and the whole stack of banknotes are conveyed reversely under the
action of the first conveyor belt assembly and the second conveyor
belt assembly and guided into the recycling box 52 by the reversing
device 25 in the reverse conveying process.
[0047] The embodiments described hereinabove are only preferred
embodiments of the present application, and should not be
interpreted as limitation to the present application. The technical
solutions claimed by the present application not only can be
applied to the financial field for processing banknotes, but also
can process checks or other whole stack of sheet-type medium which
are required to be separated piece by piece. Therefore, for those
skilled in the art, a few of modifications and improvements may be
made without departing from the spirit and scope of the present
application, and these modifications and improvements are also
deemed to fall into the scope of the present application.
