Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sheet transport devices and to sheet dispensing and receiving devices for use in dispensing and receiving sheets such as banknotes, checks and other security documents.

[0002]

BACKGROUND OF THE INVENTION Cash dispensing and receiving devices are known as separate devices for delivering cash to a customer or receiving cash from a customer. An example is disclosed in EP-A-0606721. Combined dispensing and receiving devices are also known, examples of which are GB2122008 and GB21.
No. 04877. These combined devices are relatively complex in structure, so there is a need to reduce the complexity and time and cost of such devices.

[0003]

In accordance with the present invention, a sheet transport apparatus for transporting sheets to and from a sheet stacking position has at least one outward facing opening capable of receiving a sheet. A rotatably mounted sheet transport member having a body with a groove for allowing a sheet in the groove to be transported to a sheet stacking position when the sheet transport member rotates; Has at least one reduced diameter portion, and the sheet transporting device further comprises a sheet drawer for withdrawing the sheet from the stacking position, whereby the sheet transport member is rotated during the pulling operation so that the reduced diameter portion faces the stacking position. I am trying to let you.

The inventor can use the sheet transfer member in the usual manner to transfer the sheet to the stacking position, and simply rotate the stack so that the reduced diameter portion faces the stacking position. A new type of sheet transfer device has been devised which can move the sheet transfer member without affecting the body. There is no need to pivot or move the sheet transport member away from the sheet stacking position when the sheet needs to be pulled out of the stack. This makes the structure much simpler than previous manufacturing.

The sheet transfer member may have any number of grooves depending on its size, but in a preferred example, the sheet transfer member has a pair of sheet receiving grooves and a pair of contracted portions which are located alternately with these grooves. And a diameter portion.

[0006] Typically, the transfer member is in the form of a disc and is made in one piece. However, the transfer member can be cylindrical or other shape.

Typically, if more than one transfer member is provided, the transfer members are mounted coaxially with their aligned grooves.

In some cases, the sheet is fed to and removed from the transfer member by separating means. However, as is conventional, the drawer will also be positioned to feed the sheet to the transfer member during the sheet receiving operation. This is a very simple layout that can be formed in a very simple way.

For example, the drawer may include at least one friction pulley mounted coaxially with the transfer member, the friction pulley and the reduced diameter portion of each of the sheet transfer members when the reduced diameter portion faces the stacking position. It is possible to have partially overlapping diameters.

Additionally or alternatively, at least one drawer is located near the reduced diameter portion and beyond the perimeter of the sheet transport member when the reduced diameter portion faces the stacking position.
One friction belt can be provided.

DETAILED DESCRIPTION OF THE INVENTION One example of a cash dispensing and receiving device of the present invention is described below with reference to the accompanying drawings.

The sheet transfer portion of the apparatus shown in FIGS. 1 to 5 is mounted between a pair of side plates 1A and 1B. Most drive elements (only some of which are shown) are mounted on the outside of these side plates. A transport device (only a portion of which is shown) transports the sheet from the inlet opening 2A to the sheet storage transport position 3, which transport device is wrapped around rollers and is laterally spaced apart from each other. It is defined by cooperating supply belt pairs 4, 5 (not shown in FIG. 5). The belt 5 is driven via the drive roller 6. The drive roller 6 is non-rotatably attached to the shafts 11A and 11B that are rotatably carried on a shaft 16 that is supported between the side plates 1A and 1B. The shaft 11A carries a gear 17, and the gear 17 is provided with an integral one-way clutch device (not shown) attached to a shaft 19 supported between the side plates 1A and 1B via an idle gear (not shown). Meshes with the gear 18 that has been set. Each shaft 11A, 11B is independently driven by each motor (not shown) connected to each gear 11C, 11D via a timing belt (not shown). Each belt 5 drives the cooperating belt 4 by frictional engagement. Guides 12, 13 also assist in feeding the provided sheets. Two sensor devices 14A, 14B are associated with each pair of belts 4, 5 for processing skew fed sheets as described in more detail below. The sensor devices 14A and 14B are mounted on the brackets 14C and 14D attached to the side walls 1A and 1B, respectively.

The sheet is non-rotatably attached to a shaft driven by a DC (or alternatively pulse) motor (not shown) by belts 4 and 5 and is a stacking wheel 15 (sheet transfer member is defined). To form). The shaft 16 is coaxial with the shafts 11A, 11B to which the pulley 6 is attached and extends through the shafts 11A, 11B.
A and 11B can rotate around the shaft 16. The laminating wheel 15 is a one-piece molded body having a pair of corners 20 that define the sheet receiving grooves 21 together with the main body of the wheel. The laminating wheel 15 can be seen in more detail in FIG.

The outer surface of the laminating wheel 15 has a flat portion 22 forming a pair of reduced diameter portions, and each flat portion is located between a pair of two diametrically opposed portions. In FIG. 2, the outer diameter of the laminating wheel 15 is larger than the outer diameter of the pulley 6 in the two 20 regions, whereas the diameter of the laminating wheel 15 is smaller than the diameter of the pulley 6 in the region of the flat portion 22, It can be seen that the pulley 6 (or at least the belt 5) projects or extends beyond the peripheral surface of the laminating wheel 15 in this area.

In operation, the laminating wheel 15 rotates counterclockwise as seen in FIG. 1 and the sheets arriving at the inlet 2A are conveyed by belts 4 and 5 to the laminating wheel 15 where the sheets are separately grooved 21. Be accepted by. The timing of the movement of the laminated wheel 15 is determined by the sensor devices 14A and 14A.
Control device (not shown) according to the direction of the sheet by B
Controlled by, so that the arriving sheet is correctly fed into the groove 21. The rotation of the laminating wheel 15 then carries the sheets in the groove 21 towards the sheet storage 23. The storage section 23 is defined by a sheet laminate support plate 24 attached to a lead screw 25. The sheets are formed in a stack 26 on the support plate 24 with its leading edge adjacent the vertical guide. Support plate 2
Motor 4 is used to drive the lead screw 2 in the vertical direction.
5 (or other linear positioning mechanism). The vertical position of the support plate 24 is determined according to the operating mode (dispensing or receiving) of the device in association with a sensor (not shown). Thus, when the device is to receive a sheet or when the sheet is not on the support plate 24 or the sheet has not been transferred to a store, the support plate will be the top of the support plate 24 or a stack of sheets on this plate. Banknote and stacking wheel 15
It is located so that there is a gap between and. When the sheets are fed from the reservoir 23, the support plate 24 is moved so that the topmost sheet on the stack can be pulled out of full contact with the belt 5 (as described below).

As the laminating wheel 15 rotates, all of the sheets in the grooves 21 will have one or more peeling plates 29 pivotally attached at 30 to the device (see FIGS. 2 and 3).
Taken out by the support plate 24 or the support plate 24
It falls onto the stack 26 already supported above. The support plate 24 is gradually lowered by a motor 28 as the sheets are further stacked thereon.

The sheet is pulled out of the stack 26 by frictional engagement between the friction belt 5 and the uppermost sheet on the stack and the stack is pressed against the belt 5 by a motor 28. These sheets are a pair of coaxially non-rotatably mounted shafts 19 which are normally driven counterclockwise by a drive used to rotate one of the drive rollers 6 via a one-way clutch. A separating roller 31 attached to the downstream roller 33, 34
And in the same direction by the sheets pulled by the transfer rollers 36, 37) and rotatably mounted on the shaft 19 by the bearing 33A and also by the shaft 41.
To the knobs located between the rollers 33 which are rotated counterclockwise by the corresponding contact rollers 34 (rotating clockwise) which are non-rotatably mounted on. The rollers 31 and 33 have substantially the same diameter. The counter-feed roller 35 (rotated counterclockwise) fixed to the shaft 39 prevents a large number of sheets from being pulled out at the same time. The sheet is provided between a part of the guide member 12 and a part of the stripping plate 29 and also a roller 36 fixed to the shaft 45 and a corresponding roller 37 on the shaft 38.
You will be guided through the knob between and. Shaft 41,
38 and 45 are driven at a constant speed by a main transfer drive (not shown). Laterally spaced sensors 42A, 42B are provided and supported by each bracket to detect and count the leading edge of each sheet as it is picked up by the transport device, and the skewing of the sheets. If so, the rotational speed of at least one of the rollers 6 is adjusted by suitable control of a suitable drive motor to substantially straighten the sheet during transport.

The sheet is then further fed to the sheet outlet 2B through the transfer device.

The operation of the apparatus shown in FIGS. 1 to 4 will be described in more detail below.

In the sheet receiving operation, the sheet is supplied to the entrance 2A of the insertion portion into the belts 4 and 5. Belt 5
Therefore, the belt 4 is driven at a uniform speed which matches the upstream transfer speed before the inlet 2A. At this stage, the stacking wheel 15 is stationary and positioned such that the grooves 21 are aligned to receive the incoming sheet as shown in FIG. The support plate 24 is also positioned such that there is a gap between the support plate or the top sheet of the stack on the support plate and the stacking wheel 15. A controller (not shown) indicates that the continuous sheet stacking operation has started. The first sheets to be stacked are fed into the groove 21 by the belts 4 and 5. Sensor device 14
If A, 14B indicate that the leading edge of the seat is inclined, the controller adjusts the pulley 6 and thus the drive of one or both of the belts 5 so that the seat is completely in the groove 21 of the laminating wheel. It ensures that the leading edge of the fed sheet is substantially parallel to the axis of shaft 16. When the seat is fully in the groove 21, the motor coupled to the shaft 16 is actuated (or the clutch actuated) so that the laminating wheel 15 is aligned with the next groove 21 on the outside of the belts 4, 5 for the next seat. Rotate counterclockwise until you receive. This process continues until the controller sees that the last set of sheets to be laminated has entered the laminating wheel 15.

As the laminating wheel 15 rotates, each sheet is brought into alignment with the reservoir 23 and the leading edge engages the stripping plate 29 so that when the laminating wheel 15 is rotated further, the sheets are removed from the laminating sheet. It is taken out and dropped on the laminated body 26. When the controller knows that the last sheet has arrived, it causes the stacking wheels to continue to rotate until the last sheet is removed. During this step, the support plate 24 is lowered to maintain a gap between the top of the stack 26 and the stack wheel 15.

In the dispensing operation, the laminating wheel 15 is rotated to move one of the flat portions 22 around to face the laminate as shown in FIG. At this position, the belt 5 projects beyond the diameter of the laminating wheel 15 close to the laminate 26. Further, the stripping plate 29 is rotated downward and away from the laminating wheel 15 to the position shown in FIG. The support plate 24 is raised until the uppermost sheet of the stack 26 engages the belt 5 with sufficient force. The motor connected to the pulley 6 is then actuated to move the belt 5 in the direction of arrow 49 so that the uppermost sheet of the stack 26 is pushed under frictional force toward the supply rollers 33, 34, while The wheel 15 remains stationary. The movement of the belt 5 continues until the dispensing cycle is complete. Counter-feed rollers 35 resist more than one sheet being fed from the stack. Sensors 42A, 42B display this sheet as each sheet is fed and sensors 42A, 42B
If 42B senses the leading edge of the sheet at different times, this indicates that the sheet is fed at an angle and the rotational speed of at least one of the rollers 6 is adjusted to straighten the sheet. Further, as the sheets are fed from the reservoir 23, the support plate 24 is raised to maintain contact between the uppermost sheet and the belt 5. The transfer device then transfers the pulled-out sheet to the sheet outlet.

Various modifications of the above device are possible. For example, the rollers 33, 34 or 36, 37 can define a sheet thickness detector.

The transfer device can be formed in a known manner by means of a pair of belts, a pair of rollers or a vacuum supply device.

The separating roller 31 can be driven independently from the drive to the pulley 6 rather than via a one-way clutch arrangement.

Finally, a separating and conveying device can be provided for transporting the sheets to and from the parts of the device shown in FIGS. However, this is particularly convenient if a common transfer device is used, such a device being particularly shown in FIG. In this example, two sheet storage units 50 and 51 are shown, and each storage unit has the same structure as the sheet storage unit 23. The sheets are fed to the sheet store using a laminating wheel 15 similar to that described above.
These forms of the device shown in FIG. 6 are therefore not described in detail. Sheets fed to the device during a receiving operation are fed to a position that defines an inlet to a feed passage defined by a laterally spaced pair of belts 53,54. The belt 54 is driven by a drive roller 55 from a motor (not shown), and the belt 54 frictionally drives the belt 53. The turning device 56 is the belt 5
A pair of belts 59, 60 located at the other end of the passage 57 defined by 3, 54 and laterally spaced from the turning position shown (only one pair is shown in FIG. 6). Is rotatable about a point 56 '. The belt 59 is driven by a roller 61 connected to a drive motor (not shown), and the belt 59 frictionally drives the belt 60.

In the receiving operation, the controller first determines which of the storage sections 50, 51 is to receive the incoming sheet. In the state shown in FIG. 6, the incoming sheet is stored in the reservoir 50, which causes the deflector 56 to be actuated by the control device to deflect away from the sheet path 58, while the deflector 62 is deactivated. The sheet turned by the turning device 56 enters the carry-in passage 64, from which the sheet enters the groove of the laminating wheel 15 as before. After a sheet or a group of sheets has been fed, the deflectors 56, 62 are deactivated. When this incoming sheet is fed to the store 51, the deflector 56 remains inoperative and the deflector 62 remains in its activated position 6.
Moved to 2 '(shown in phantom), the sheet is fed through the deflector 62 into the passage 63 and from there into the groove of the laminating wheel 15.

In the distribution operation, both turners 56,
62 is deactivated. A suitable laminating wheel 15 is rotated so that its flat portion faces the reservoir, the stripping plate 29 is moved apart, and the reservoirs 50,51.
One of the support plates of the
To be engaged. The topmost sheet is then withdrawn and fed along passageway 65 or 66 so that it engages each deflector 56,62. In the inactive state, the deflector is free to rotate under the action of the seat, whereby the deflector is gradually rotated by the seat and the seat is guided to the corresponding passage 57 or 58 (for example in FIG. 6). Position 62 '). Further, during the dispensing operation, the belts 53, 54, 59, 60 are moved in opposite or opposite directions so that the dispensed sheets are fed back to position 52 and from there through the transfer device to the outlet. To do so.
