EP3425601B1 - Cash box with a receiving area for recording bank notes - Google Patents

Description

The invention relates to a cashbox with a receiving area in which several notes of value can be received as a stack of notes. A counterpressure unit, which delimits the receiving area, is movable in a deposit direction and counter to the deposit direction between a first position in which the receiving area has a minimum volume and a second position in which the receiving area has a maximum volume.

Cash boxes are known from the prior art, in which counterpressure units are provided that can be moved in the deposit direction and against the deposit direction to exert a counterpressure force on the stack of notes. These counterpressure units enable secure deposit of the notes by holding the previously received notes in their stacked form, with the stacking direction running vertically or horizontally. From the document DE 10 2008 018 935 A1 For example, a single-sheet handling device is known in which the notes of value are stacked horizontally, i.e. standing on one edge. From the document EP 2 738 745 A1 A cash box is known in which the notes of value are stacked vertically, i.e. lying on the front or back.

When changing cash boxes or during inventory checks, it is necessary to check whether any notes are still in the cashbox. Currently, there are no known solutions that allow a simple check to determine whether a cashbox is empty. For example, checking the position of the counterpressure unit is usually not sufficient for this detection due to the small height of the notes, as the measurement accuracy is usually not high enough to reliably determine even the presence of a single note.

document US 2013/277382 A1 discloses a cashbox with a receiving area defined by a counter-pressure unit. The counter-pressure unit is movable between a first position with a minimum volume of the receiving area and a second position with a maximum volume of the receiving area. A sensor unit with a sensor element detects a first sensor element position when at least one note of value is located between the sensor element and the counter-pressure unit, with a front or back side contacting the sensor element. In this case, the sensor element is moved downwards, i.e., in the deposit direction of the notes, by contact with the note of value against the spring force.

The object of the invention is to provide a cashbox for receiving notes of value in a receiving area, in which it is determined by means of a simple check whether the cashbox is empty. This object is achieved by a cashbox having the features of claim 1 or by an arrangement having the features of claim 2, as well as by a method having the features of the independent method claim.

Advantageous further developments are specified in the dependent claims, whereby the features of the dependent claims can be used to further develop both the cash box, the arrangement and the method.

The cashbox, the arrangement or the method of the respective independent claim ensures that a control unit determines whether the cashbox is empty, wherein the determination is based on the sensor signal of the sensor unit and the position of the counter-pressure unit. The sensor signal is particularly dependent on the position of the sensor element of the sensor unit, which can be accommodated in a recess of the counter-pressure unit. The sensor element and the recess are arranged and designed such that the sensor element is only accommodated in the recess when the counter-pressure unit is in the first position and there is no note of value between the sensor element and the recess. This enables simple and reliable determination and checking of the empty state of the cashbox. The sensor signal can be transmitted from the sensor unit to the control unit as a signal level via control lines or encoded in data, in particular with the aid of data packets.

The sensor unit detects a first sensor element position of the sensor element when at least one note of value is located between the sensor element and the counterpressure unit, with its front or back contacting the sensor element. Contact with the note moves the sensor element against the deposit direction. This ensures that the presence of a note of value is always detected when the counterpressure unit is in a position where the note of value can contact the sensor element.

It is particularly advantageous if the control unit detects the 'cashbox empty' state when the counterpressure unit is in the first position and the sensor element is not in the first sensor element position. Furthermore, it is advantageous if the control unit detects the 'cashbox not empty' state when the counterpressure unit is in the first position and the sensor element is in the first sensor element position. This enables simple and reliable detection of the 'cashbox empty' and 'cashbox not empty' states.

According to the invention, several notes of value received in the receiving area form a stack of notes of value. In an operating position of the cashbox, the notes of the stack of notes of value can be arranged one above the other in such a way that the bottommost note rests with its front or back on the counter-pressure unit. This enables secure and reliable storage of the notes of value.

The invention comprises a control unit which, when notes of value are fed into the cashbox, based on the sensor signal that the sensor element is in the first sensor element position, controls the counter-pressure unit in such a way that the counter-pressure unit is moved in the deposit direction until the sensor element is no longer in the first sensor element position and the sensor unit outputs a corresponding sensor signal. As a result, a feed gap above the stack of notes of value into which further notes of value can be added.

Furthermore, it is advantageous if the sensor unit comprises a detection element, wherein the detection element generates the sensor signal indicating whether the sensor element is arranged in the first sensor element position or not and transmits it to the control unit. The detection element preferably comprises at least one light barrier. Thus, precise detection of the sensor element position can be achieved with the aid of the sensor unit.

It is particularly advantageous if a feeding and/or separating unit is provided for feeding and/or removing the notes of value, whereby the notes of value can be fed into or removed from the receiving area one after the other using the feeding and separating unit. This allows notes of value to be easily fed into and removed from the receiving area.

In an advantageous embodiment, a drive unit is provided for moving the counter-pressure unit, in particular an electric motor, such as a DC motor or a stepper motor. This allows for simple drive of the counter-pressure unit. It is particularly advantageous if the control unit determines the first position of the counter-pressure unit, in which the counter-pressure unit rests against a stop, by means of a current measurement of the motor current of the The position is determined by the electric motor or by counting the stepper motor. This allows for reliable determination of the first position of the counterpressure unit.

Furthermore, it is advantageous if the counterpressure unit is firmly connected to at least one belt, wherein the belt is driven by the drive unit, so that a simple and cost-effective drive of the counterpressure unit is possible.

It is particularly advantageous if the recess of the counterpressure unit is 5 mm to 7 mm, in particular 5.5 mm to 6 mm, wide and if the sensor element which is received in the recess is 2 mm to 4 mm wide, in particular 2.5 mm to 3 mm.

Figure 1 shows a perspective view of a cashbox 100 in a horizontal position. The cashbox 100 has a housing 120 with a base body 112, which comprises a front side 110, a top side 111, a bottom side 114 and two lateral boundaries 118, 122. The two lateral boundaries 118, 122 of the base body 112 are each partially covered by a cover plate 124, wherein Figure 1 Due to the selected perspective, only one of the two cover plates 124 is visible. The rear side of the housing 120 of the cashbox 100 is formed by a cover plate 116 connected to the housing 120. In Figure 1 Also shown are a handle 128 for transporting the cash box 100, a feed slot 126 for feeding notes 10 (not shown), and four vanes 131a, 131b, 131c, 131d, which protrude from the housing 120 and are components of four vane wheels 130a to 130d.

Figure 2 shows a perspective view of the cashbox 100 according to Figure 1 in vertical position. Elements with the same structure or function have the same reference numerals. Figure 2 The vertical position of the cashbox 100 shown in the exemplary embodiment corresponds to the operating position of the cashbox 100 in which the cashbox 100 is used in a device for handling notes of value 10. In Figure 2 a gear 142 is visible, which is brought into engagement with a drive unit (not shown) located outside the cashbox 100 when the cashbox 100 has been inserted, for example, into a device for handling notes of value, such as an ATM or an automatic safe or an automatic cash register system.

Figure 3 shows a perspective view of the internal structure of the cashbox 100 according to the Figures 1 and 2 in a first operating state. The cashbox 100 comprises a feed unit 300 for feeding notes of value 10 (not shown) and a receiving area 200 in which the notes of value 10 are received. The receiving area 200 is delimited by a counterpressure unit 210, which is firmly connected to a belt 212 via a first connecting element 220 and to a belt 214 via a second connecting element 222. The belt 212 is guided over rollers 216a and 216b serving as deflection elements, and the belt 214 is guided over rollers 216c and 216d serving as deflection elements.

The rollers 216b and 216d are mounted on a Figure 3 fixedly arranged on a non-visible drive shaft 221, which is drivable by a drive unit 400, wherein a gear stage 402, in particular a transmission gear, is provided for transmitting the drive force of the drive unit 400 to the drive shaft 221. The rollers 216a and 216c are mounted on a non-driven shaft 223, which is Figure 3 is covered by the counterpressure unit 210.

In Figure 3 The counterpressure unit 210 is shown in a first operating state in which the counterpressure unit 210 is arranged at a second position indicated by the line P1, wherein the volume of the receiving area 200 is maximum in this second position P1. With the aid of the drive unit 400, the counterpressure unit 210 can be moved counter to a depositing direction A1 and in the depositing direction A1 between the line P1 and a line PO. The line PO indicates a position of a mechanical stop element, which in this exemplary embodiment corresponds to a stop of a limiting element 310. If the counterpressure unit 210 is arranged at the first position indicated by the line PO, the volume of the receiving area 200 is minimal.

A control unit 500 monitors the position of the counterpressure unit 210 and controls the drive unit 400, wherein the drive unit 400 in the exemplary embodiment comprises a DC motor. The control unit 500 measures the motor current and detects whether the counterpressure unit 210 is in the first position, i.e., on the line P0, when the counterpressure unit 210 is pressed by the drive unit 400 against the stop or against the limiting element 310, so that the motor current increases. In an alternative embodiment, the drive unit 400 can also comprise a stepper motor instead of the DC motor. wherein the position determination of the counterpressure unit 210 is carried out by means of a step count of the stepper motor by the control unit 500. Alternatively or additionally, a further sensor unit can also be provided for detecting the position of the counterpressure unit 210.

In the present embodiment, the feed unit 300 comprises four impellers 130a to 130d, which are arranged in a rotationally fixed manner on a drive shaft 140 and each have three vanes 131a to 133d projecting tangentially from a hub 135a to 135d. The drive shaft 140 is driven by a further drive unit (not shown) to feed notes of value 10 into the receiving area 200. The shaft 140 is connected to the further drive unit via the gear 142, which is rotationally fixedly connected to the shaft 140 and protrudes from the housing 120 of the cashbox 100. A drive roller 136a is arranged between the impellers 130a and 130b, and a drive roller 136b is rotationally fixedly connected to the shaft 140 between the impellers 130c and 130d. The two drive rollers 136a and 136b extend into the feed slot 126, which is delimited by the limiting element 310 and a second limiting element 320. Opposite the two drive rollers 136a and 136b, a non-driven roller 138a and 138b is arranged, which Figure 3 are covered by the drive rollers 136a and 136b and serve as pressure rollers 138a, 138b.

When a note is fed in, the shaft 140 is rotated, causing the impellers 131a to 133d and the Drive rollers 136a and 136b are connected. With the aid of the drive rollers 136a and 136b, the note of value is guided through the feed slot 126 in a feed direction Z1, wherein the note of value is pressed against the rollers 138a and 138b, thereby causing the two rollers 138a and 138b to rotate. After passing through the feed slot 126, at least one wing 131a to 133d contacts the note of value and presses it in the deposit direction A1 into the receiving area 200 of the cashbox 100.

As in Figure 3 As shown, the cashbox 100 comprises a sensor element 610, which in the described embodiment has the shape of a skid or a lever. The sensor element 610 is 2 mm to 4 mm, in particular 3 mm, wide and has a weight of 2 g to 5 g, in particular 3 g. The sensor element 610 can be received in a recess 620 of the counter-pressure unit 210 when the counter-pressure unit 210 is in the first position PO. The recess 620 of the counter-pressure unit 210 is 5 mm to 7 mm, in particular 5.5 mm to 6 mm, wide.

Figure 4 shows a plan view of the internal structure of the cashbox 100 according to the Figures 1 to 3 The sensor element 610 is pivotally connected to the limiting element 310 by means of a connecting element 614. In the Figure 4 In the horizontal position of the cashbox 100 shown, the sensor element 610 projects into a light barrier arrangement 612. In the vertical operating position of the cashbox 100, the sensor element 610, in the Figure 3 shown operating state, by gravity in the direction of deposition A1 moves out of the light barrier arrangement 612.

The light barrier arrangement 612 comprises an optical transmitter 614 for emitting light and an optical receiver 616 for receiving the light emitted by the transmitter 614. The transmitter 614 and the receiver 616 are arranged such that when the sensor element 610 is positioned between the optical transmitter 614 and the optical receiver 616, the light beam emitted by the transmitter 614 is interrupted. This interruption is detected by the receiver 616, which transmits a corresponding first sensor signal to the control unit 500. The sensor element 610 and the light barrier arrangement 612, which serves as a detection element, together form a sensor unit 600.

Figure 5 shows a perspective view of part of the internal structure of the cashbox according to the Figures 1 to 4 in which the counter-pressure unit 210 with the recess 620 and elements for moving the counter-pressure unit 210 in the receiving area 200, from the first position PO towards the second position P1, ie in the depositing direction A1, as well as in the opposite direction, are visible.

Figure 6 shows a vertical sectional view according to the Figures 1 to 5 along the section line II in a second operating state in which the counterpressure unit 210 is positioned at the first position PO, so that the Receiving area 200 has the smallest volume. For this purpose, the counterpressure unit 210 has been moved with the aid of the drive unit 400 against the depositing direction A1 to the line PO. A note of value 10, which is arranged between the counterpressure unit 210 and the sensor element 610, contacts the sensor element 610 and deflects it against the depositing direction A1 into a first sensor element position, in which the sensor element 610 interrupts the light beam between the transmitter 614 and the receiver 616 of the light barrier arrangement 612. The receiver 616 sends a corresponding first sensor signal to the control unit 500, which detects the status 'cash cassette not empty' from this first sensor signal and the information that the counterpressure unit is in the first position.

Figure 7 shows a vertical sectional view of the cashbox according to the Figures 1 to 6 along the section line II in a third operating state, in which the counterpressure unit 210 in the same way as in the Figure 6 shown second operating state is positioned at the first position P0, i.e. the receiving area 200 has the smallest volume. For this purpose, the counter-pressure unit 210 has been moved by means of the drive unit 400 against the depositing direction A1 up to the line PO, so that it rests against the stop of the limiting element 310. In contrast to the second operating state, there is no note of value between the sensor element 610 and the counter-pressure unit, so that a part of the sensor element 610 is received in the recess of the counter-pressure unit 210. As a result, the light beam between the transmitter 614 and the receiver 616 is not interrupted, so that the receiver 616 receives a corresponding transmits a second sensor signal to the control unit 500. From the information that the counterpressure unit is in the first position and the second sensor signal that the light beam of the light barrier arrangement 612 is not interrupted by the sensor element 610, the control unit 500 determines the 'cashbox empty' state.

Figure 8 shows a vertical sectional view according to the Figures 1 to 7 along the section line II in a fourth operating state, in which several notes of value 10 are fed to the receiving area 200 of the cashbox 100. Figure 9 shows a vertical sectional view according to the Figures 1 to 8 along the section line II in a fifth operating state, in which another note 12 is fed into the cashbox 100. In Figure 8 the notes of value 10 deflect the sensor element 610 counter to the deposit direction A1 from the recess 620 into its first sensor element position, in which the light beam between the transmitter 614 and the receiver 616 is interrupted by the sensor element 610. In contrast to the second and third operating states, the counterpressure unit 210 is not in position P0.

The receiver 616 transmits the first sensor signal to the control unit 500, which indicates that the sensor element 610 is in the first sensor element position. The control unit 500 subsequently controls the drive unit 400 to drive the counterpressure unit 210 in such a way that the counterpressure unit 210 moves in the deposition direction A1 until the sensor unit 500 receives the second sensor signal for control unit indicating that the sensor element 610 is no longer in the first sensor element position. Figure 9 shows the operating state in which the sensor element 610 is no longer in its first sensor element position, so that a feed gap has been formed above the stack of notes into which a new note 12 of the cashbox 100 is fed.

In an alternative embodiment, an analog detection element for detecting the sensor element position can be provided instead of the light barrier arrangement 612. Alternatively, the sensor unit 600 can also comprise a digital detection element that detects more than two different positions of the sensor element 610. In alternative embodiments, the sensor element 610 can be displaceably arranged in the feed unit and/or be subjected to a spring force that biases the sensor element 610 toward the receiving area 200.

9. Cash box or device according to Claim 7, characterized in that the counterpressure unit (210) is fixedly connected to at least one belt (212, 214), wherein the belt (212, 214) is driven by the drive unit (400).
10. Cash box or device according to one of the preceding claims, characterized in that the cutout (620) in the counterpressure unit (210) is 5 mm to 7 mm, in particular 5.5 mm to 6 mm, wide, and in that the sensor element (610), which is received in the cutout (620), is 2 mm to 4 mm, in particular 2.5 mm to 3 mm, wide.
11. Method for receiving several notes of value (10, 12) in the form of a stack of notes of value in a receiving region (200) of a cash box (100) according to Claim 1 or arranged in the device according to Claim 2,

    wherein the receiving region (200) is delimited with the aid of a counterpressure unit (210), wherein the counterpressure unit (210) can be moved between a first position, in which the receiving region (200) has a minimum volume, and a second position, in which the receiving region (200) has a maximum volume, wherein a sensor signal, which is dependent on the position of the sensor element (610), is generated with the aid of a sensor unit (600) having at least one sensor element (610),

    wherein the sensor element (610) is received in a cutout (620) of the counterpressure unit (210) when there are no notes of value (10, 12) between the counterpressure unit (210) and the sensor element (610),

    wherein it is determined on the basis of the sensor signal and the position of the counterpressure unit (210) whether the cash box (100) is empty,

    wherein the sensor unit (600) detects a first sensor element position of the sensor element (610) when at least one note of value (10, 12), which by way of its front side or rear side makes contact with the sensor element (610), is between the sensor element (610) and the counterpressure unit (210),

    wherein the sensor element (610) is moved counter to the depositing direction (A1) owing to the contact with the note of value (10, 12),

    wherein several notes of value (10, 12) that have been received in the receiving region form a stack of notes of value, wherein the notes of value (10, 12) in the stack of notes of value are arranged one above the other in an operating position of the cash box (100) in such a way that the lowermost note of value (10, 12) rests by way of its front side or its rear side on the counterpressure unit (210), characterized in that, when notes of value (10, 12) are fed into the cash box (100) based on the sensor signal that the sensor element (610) is in the first sensor element position, the counterpressure unit (210) or a drive unit of the counterpressure unit (210) is actuated in such a way that the counterpressure unit (210) is moved in the depositing direction (A1) until the sensor element (610) is no longer in the first sensor element position and the sensor unit (600) outputs a corresponding sensor signal.
