Description

Media access device

[0001] The present invention relates to a media input / output device, and more specifically, to a media input / output device that receives and discharges media using an escrow-type drum.

[0002] Generally, an Automated Teller Machine (ATM) is an automated device capable of assisting with basic financial services, such as deposits or withdrawals, regardless of location or time and without the need for bank staff; it is configured to allow customers to automatically withdraw banknotes or perform transactions, such as deposits, using media such as cards or passbooks.

[0003] These financial automation devices are equipped with a media entry / exit device comprising a transfer device for the entry and exit of media, a device for identifying or inspecting media, and a device for receiving media or releasing received media.

[0004] Recently, an escrow function is being applied to temporarily store media inserted into media access devices.

[0005] A media entry / exit device having an escrow function is configured to store media between a pair of films wound on the surface of a drum that rotates in one direction, and to discharge the stored media by rotating the drum in the opposite direction.

[0006] For example, the applicant has disclosed and filed patent applications for a technology of an escrow-type media access device in a number of documents, including Patent Document 1 and Patent Document 2 below, and has been registered.

[0007] A media input / output device according to the prior art stores or discharges media by winding or unwinding a total of two pairs of films, one pair each on the left and right sides of the drum.

[0008] Accordingly, the media entry / exit device according to the prior art is configured to include a total of two pairs of supply rollers so that each film can be supplied to or retrieved from the drum.

[0009] As such, since the media entry / exit device according to the prior art uses a total of two pairs of films, various components such as supply rollers for supplying each film, drive motors for driving the supply rollers, and sensors for detecting the condition of each film are applied in two pairs, the configuration becomes complex, manufacturing costs increase due to the increase in the number of parts, and workability may be reduced during manufacturing.

[0010] And media in various states are introduced into the above-mentioned media input / output device.

[0011] Media that has been recently issued, such as new banknotes, is in good condition, so there is a low likelihood of malfunction or damage caused by the media when inserted into the media access device. On the other hand, as media usage accumulates, it deteriorates, resulting in creases or folds, which increases the likelihood of problems such as jamming inside the access device. Consequently, the access device faced issues where the storage space required for aging media increased, and failures could occur due to media being stored in abnormal forms.

[0012] Accordingly, the media access device according to the prior art had a problem in that it was difficult to effectively perform maintenance work in a narrow internal space when a jam occurred due to one or more of the films getting stuck because of the aging media.

[0013] Therefore, there is a need to develop media entry / exit device technology that simplifies the structure by minimizing the number of films to be stored in the drum and secures space for maintenance work.

[0014] (Patent Document 1) Republic of Korea Patent Registration No. 10-2490058 (Published January 19, 2023)

[0015] (Patent Document 2) Republic of Korea Patent Registration No. 10-2423418 (Published July 22, 2023)

[0016] The objective of the present invention is to solve the problems described above by providing a media entry / exit device capable of storing or discharging a medium by winding or unwinding a film on the surface of a rotating drum.

[0017] Another objective of the present invention is to provide a media entry / exit device capable of storing or discharging media using a pair of films wound on both sides of a drum, and guiding the stored or discharged media to move accurately.

[0018] Another objective of the present invention is to provide a media access device that simplifies the configuration by minimizing the number of films applied to the media access device and enables effective maintenance work in the event of an abnormality such as a film jam.

[0019] To achieve the above-mentioned purpose, the media input / output device according to the present invention comprises a drum that rotates in forward and reverse directions and a pair of reels that rotate in synchronization with the rotational movement of the drum to supply or retrieve a film wound on its outer surface through a transport path to both sides of the drum, and is characterized by storing a media between the film wound on the outer surface of the drum and the film wound on the outer surface of the drum by the forward rotational movement of the drum, and discharging the media stored in the drum by the reverse rotational movement of the drum.

[0020] As described above, according to the media entry / exit device of the present invention, a media can be stored or discharged using a pair of films wound on both sides of a rotating drum, and the effect of guiding the stored or discharged media to move accurately is obtained.

[0021] And according to the present invention, the effect of being able to remove a pair of reels positioned on the lower side in the prior art and to remove the motor and rollers applied to move the film from the removed pair of reels to the drum is obtained.

[0022] Accordingly, according to the present invention, by efficiently utilizing the space occupied by each part removed from inside the housing, space utilization can be improved, and maintenance work can be easily performed in the event of a jam caused by aging of the medium.

[0023] In addition, according to the present invention, the effect of being able to transport the medium to an accurate position by using a moving guide that rotates according to the storage volume of the film and the medium is obtained.

[0024] Accordingly, according to the present invention, the position where the medium is stored in the drum is accurately controlled to improve the integration performance, and the effect of effectively preventing jamming caused by the medium getting stuck or the film getting tangled during the process of discharging the medium stored in the drum is obtained.

[0030] A media access device according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0031]

[0032] FIG. 1 is a perspective view of a media access device according to a preferred embodiment of the present invention, FIG. 2 is a perspective view showing the front and top surfaces shown in FIG. 1 in an open state, and FIG. 3 is a cross-sectional view along the line AA' shown in FIG. 1.

[0033] Figure 3 shows the state in which the housing shown in Figure 1 has been removed.

[0034] In the following, terms indicating directions such as 'left (L)', 'right (R)', 'forward (F)', 'rear (B)', 'upward (U)', and 'downward (D)' are defined as indicating the respective directions based on the state depicted in each drawing.

[0035]

[0036] As shown in FIGS. 1 to 3, a media input / output device (10) according to a preferred embodiment of the present invention comprises a housing (20) forming an outer shape, a drum (30) provided inside the housing (20) and rotating in forward and reverse directions, a pair of reels (40) that rotate in synchronization with the rotational movement of the drum (30) to supply or retrieve a film (11) wound on an outer surface to the drum (30) through a transfer path (P1), and a movement guide part (50) that guides the movement of the media introduced through the transfer path (P1) to supply between the film (11) and the outer surface of the drum (30) and to discharge the media stored in the drum (30) through a discharge path (P2).

[0037] And, the media input / output device (10) according to a preferred embodiment of the present invention may further include a branching section (60) that supplies the media introduced through the input path (P3) to the transfer path (P1) and branches the movement path to move the media discharged through the transfer path (P1) to the discharge path (P2), and a roller section (70) that moves the media along the discharge path (P2) and the input path (P3).

[0038] The housing (20) may include an upper cover (21), a front cover (22), and a pair of side covers (23) respectively positioned on the top, front, and both sides so that the external shape of the media entry / exit device (10) is approximately a tubular shape.

[0039] The upper cover (21) is positioned across a portion of the upper surface and a portion of the front surface of the housing (20), and can open and close the internal space of the housing (20) by rotating in an up-and-down direction around a rotation axis connected to the rear end of the upper cover (21) as shown in FIG. 2.

[0040] The front cover (22) shields the front center of the housing (20) and can open and close the internal space of the housing (20) by rotating in an up-and-down direction around a rotation axis connected to the lower part of the front cover (22).

[0041] Therefore, the manager can open the upper cover (21) and the lower cover (22) to easily perform maintenance work on each part placed inside the housing (20).

[0042] Of course, the housing (20) can be disassembled by releasing the bolt assembly of the remaining parts other than the upper cover (21) and the front cover (22).

[0043] A pair of side covers (23) are provided on each side of the housing (20), and inside the side cover (23) provided on one side of the housing (20), for example on the right side, a printed circuit board on which a control unit for controlling the operation of each device is installed, a power supply unit, and a heat dissipation unit for discharging heat generated during operation may be installed.

[0044] A pair of frames (24) may be provided on both sides of the internal space of the housing (20), on which parts are mounted so that the rotation axes of each device are rotatably installed or fixedly installed. Of course, the number and shape of the frames (24) may be varied.

[0045] The drum (30) is connected to a driving unit, such as a motor, to rotate the reel (40) described below, and to a power transmission member such as a belt, pulley, or gear, so that it rotates, and the film (11) can be wound to a preset length on the outer surface of the drum (30) in an initial state before the medium is stored.

[0046] For example, if the total length of the film (11) is about 30 m, one end of the film (11) can be wound about 1 m to 3 m.

[0047] In the following description, the part of the film (11) that is wound around the outer surface of the drum is referred to as the ‘wound film (12)’, and the part that is supplied from the reel (40) to receive the medium by the rotational movement of the drum (30) and the reel (40) and is in a state before being wound onto the drum (30) is referred to as the ‘wound film (13)’.

[0048] As the media storage operation proceeds, the length, i.e., the thickness, of the film (12) wound around the outer surface of the drum (20) increases, and during the media storage and discharge operation, the length of the wound film (12) and the film being wound (13) can increase or decrease in a complementary manner.

[0049] The drum (30) is formed in a roughly cylindrical shape and can function to store a medium by winding it between the wound film (12) and the film being wound (13), or to unwind the stored medium.

[0050] These drums (30) can be divided into multiple parts and combined to a single rotation axis (31).

[0051] Here, a first operating lever (32) may be installed at one end of the rotating shaft (31) on which the drum (30) is installed so that the drum can be rotated by manual operation during maintenance work.

[0052] For example, the first operating lever (32) may be installed at the left end of the rotating side (31) that protrudes through the frame (24) positioned on the left side of a pair of frames (24).

[0053] A pair of reels (40) each function to wind or unwind a film (11) for storing and discharging media. Each reel (40) is connected to a driving unit, such as a motor, and can rotate in synchronization with the rotation of the drum (30).

[0054] These pairs of reels (40) can be arranged side by side at a certain distance from each other on one side of the drum (30), for example, the upper rear side, so as to supply a pair of films (11) to both sides of the medium stored in the drum (30).

[0055] Between the reel (40) and the drum (30), one or more pairs of rollers and guides may be installed to form a movement path for the film (11) and to maintain constant tension of the film (11).

[0056] Meanwhile, a media input / output device according to the prior art supplies two pairs of films to a drum and stores a medium between each pair of films.

[0057] On the other hand, in this embodiment, only a pair of films (11) are supplied to both sides of the drum (30), and a medium can be inserted and stored between the film (12) wound on the outer surface of the drum (30) and the film (13) being wound from each film (11).

[0058] In this way, the present invention can remove a pair of reels positioned on the lower side in the prior art, and remove motors and rollers applied to move the film from the removed pair of reels to the drum.

[0059] Therefore, the present invention can improve space utilization by efficiently utilizing the space occupied by each part removed from inside the housing, and can facilitate maintenance work in the event of a jam caused by aging of the medium.

[0060] The moving guide section (50) may include a switching member (51) that switches the direction of transfer so that the medium being transferred along the transfer path (P1) is transferred toward the drum (30), and a guide member (52) that guides the movement of the medium being inserted toward the drum (30) or discharged from the drum (30) from the switching member (51).

[0061] The switching member (51) is installed on the upper front side of the internal space of the housing (20) and can be formed with a cross-section approximately 'L' shape when viewed from the right side in order to switch the direction of transfer so that the medium being transferred along the transfer path (P1) in an approximately vertical direction is transferred to the rear or front toward the drum (20).

[0062] An outer guide that guides a medium moving along the switching member (51) may be further installed on the outer side of the switching member (51), that is, on the front and upper sides.

[0063] The guide member (52) functions to guide the medium being transported along the switching member (51) toward the film (12) wound on the outer surface of the drum (30) and the film (13) being wound.

[0064] These guide members (52) can be installed so as to be rotatable around the lower end so as to adjust the direction of transport of the medium according to the length of the film (12) wound on the drum (30) and the quantity of the medium.

[0065] Figure 4 is a partial enlarged view of the drum, guide member, and branching section.

[0066] As shown in FIGS. 3 and 4, the guide member (52) has a cross-section formed in an approximate 'Y' shape or 'T' shape, and the lower end of the guide member (52) can be connected to a rotation axis.

[0067] At the top of the guide member (52), a front extension (53) and a rear extension (54) extending toward the front and rear may be provided.

[0068] The rear extension (54) is a part that contacts the film (12) wound on the outer surface of the drum (30), and the rear surface of the rear extension (54) can be formed as a curved surface corresponding to the curvature of the film (12) wound on the drum (30).

[0069] And the upper surfaces of the front extension (53) and the rear extension (54) can each be formed as a plurality of flat or curved surfaces having different angles so as to correspond to the angle of the film (13) wound on the drum (30) from the transmission member (51).

[0070] Therefore, the guide member (52) can guide the media to move to an accurate position, that is, between the wound film (12) and the film being wound (13), by rotating it around the rotation axis of the lower part according to the length of the wound film (12) and the quantity of the media, while the rear extension part (54) is in contact with the film (12) wound on the outer surface of the drum (30).

[0071] Here, an elastic member (55) providing elastic force may be installed on the front surface of the guide member (52) so that the guide member (52) can be in close contact with the film (12) wound on the drum (30).

[0072] For example, the elastic member (55) is provided as a plate spring, the upper end of the elastic member (55) is supported on the front of the guide member (52), and the lower end of the elastic member (55) can be supported on a surrounding part or structure that is fixedly installed in the internal space of the housing (20).

[0073] Of course, when storing the media, the guide member (52) rotates forward around the bottom part according to the amount of film (11) and media being wound and stored, and when discharging the media, it rotates backward around the bottom part, and can return to its original position when all media are discharged.

[0074] In this way, the present invention can transport the medium to an accurate position by using a moving guide that rotates according to the storage volume of the film and the medium.

[0075] Accordingly, the present invention can improve the integration performance by accurately adjusting the position where the medium is stored in the drum, and effectively prevent jamming caused by the medium getting stuck or the film getting tangled during the process of discharging the medium stored in the drum.

[0076] The branching section (60) can be positioned between the transfer path (P1), the discharge path (P2), and the input path (P2). Thus, the branching section (60) functions to guide the medium introduced through the input path (P3) to be transferred to the transfer path (P1) for supply, and to guide the medium discharged to the outside through the transfer path (P1) to be transferred to the discharge path (P2) for discharge to the outside.

[0077] This branching section (60) may include a hinged section (61) that is hinged between the input path (P3) and the output path (P2), and a tapered section (62) that is integrally formed with the hinged section (61) and extends upward and gradually narrows in width toward the top.

[0078] A spring member providing elastic force may be installed in the interior of the hinge joint (61) or in the rotating shaft coupled to the hinge joint (61) so that one side of the end of the tapered portion (62), i.e., the front side, is pressed toward the input path (P3) and elastically supported.

[0079] In this way, the branching section (60) is formed such that the width of the tapered section (62) gradually narrows toward the top, and as one side of the top of the tapered section (62), namely the rear side, is pressed toward the input path (P3) and elastically supported, the discharge path (P2) can be naturally formed by the other side of the branching section (60).

[0080] And as the branch section (60) is formed such that the width of the tapered section (62) gradually narrows toward the top, the input medium can be supplied to the transfer path (P1) through the input path (P3) while pushing the front of the tapered section (62) backward with a small input force.

[0081] The roller section (70) transports the medium introduced from the outside into the interior of the medium entry / exit device (10) and transmits the medium discharged from the interior of the medium entry / exit device (10) to the outside.

[0082] That is, the roller section (70) functions to feed the medium fed through the input path (P3) into the transfer path (P1) and to move the medium discharged through the transfer path (P1) to be discharged to the outside through the discharge path (P2).

[0083] To this end, the roller section (70) may include a plurality of pairs of rollers (71) rotatably installed along the input path (P3) and the discharge path (P2).

[0084] Accordingly, when a medium is introduced, the medium is introduced into the interior of the medium entry / exit device (10) through the introduction path (P3) formed by the plurality of pairs of rollers (71) and the branching section (60), and when a medium is discharged, the medium can be smoothly discharged to the outside of the medium entry / exit device through the discharge path (P2).

[0085] Each of these multiple pairs of rollers (71) is installed on a rotating shaft positioned at a corresponding location, and the rotating shaft can rotate by receiving rotational force through a driving unit such as a motor by means of a power transmission member such as a gear, pulley, or belt.

[0086] Here, a second operating lever (72) may be installed on the left end of the rotating side of the driving roller that rotates by directly receiving the driving force among the multiple pairs of rollers (71) so that the multiple pairs of rollers can be rotated by manual operation during maintenance work.

[0087] Meanwhile, a first detection sensor (81) for detecting the total thickness of the film (12) wound on the drum (30) may be installed on one side of the drum (30), for example, the lower rear side, and a second detection sensor (82) for detecting the medium present on the transport path (P1) may be installed on the rear side of the transport path (P1).

[0088] For example, the first and second sensing sensors (81, 82) can be provided as various sensor units such as infrared sensors, light sensors, and proximity sensors.

[0089] Therefore, the control unit controlling the operation of the media entry / exit device (10) can check whether the total thickness of the film (12) wound on the outer surface of the drum (30) and the media exceeds a preset thickness based on the detection signal of the first detection sensor (81).

[0090] Here, the set thickness can be set to the maximum value at which the film (11) and the medium can be wound around the outer surface of the drum.

[0091] Accordingly, the control unit can limit the maximum input amount of the medium by stopping the medium storage operation when the detected thickness exceeds the set thickness and controlling the discharge of the stored medium through the discharge passage (P2), thereby preventing the film (11) from being wound beyond the maximum value.

[0092] And the above control unit can control the operation of each driving unit to rotate the drum (30) and the reel (40) until all the medium present on the transport path (P1) is transported based on the detection signal of the second detection sensor (82), and can control the operation of each driving unit to stop when there is no medium present on the transport path (P1).

[0093]

[0094] Next, with reference to FIGS. 5 and FIGS. 6, the operation method of a media access device according to a preferred embodiment of the present invention will be described in detail.

[0095] FIGS. 5 and FIGS. 6 are drawings illustrating the media storage operation state and the discharge operation state of a media access device according to a preferred embodiment of the present invention, respectively.

[0096] First, the operation of receiving and storing media using the media input / output device is explained.

[0097] When receiving the medium, as shown in FIG. 5, the medium is introduced through the input path (P3). At this time, a plurality of pairs of rollers (71) provided in the roller section (70) rotate in one direction and move the medium upward along the input path (P3) toward the transfer path (P1).

[0098] The branching section (60) is elastically supported by a spring member so that the tapered section (62) is positioned at an angle toward the front and upward, and when the medium moves upward and presses the front of the tapered section (62) toward the rear, it rotates backward around the hinge joint (61) at the bottom.

[0099] Accordingly, the input path (P3) and the transfer path (P1) are connected, and the medium passes through the branching section (60) and enters the transfer path (P1).

[0100] The medium that has entered the interior of the transport path (P1) is transported upward along the transport path (P1) by the rotation of rollers provided on both sides of the transport path (P1).

[0101] At this time, the switching member (51) and the outer guide of the moving guide part (50) provided at the top of the transfer path (P1) switch the transfer direction of the medium from upward to backward.

[0102] Then, the guide member (52) uses an upper surface formed of a plurality of flat or curved surfaces having different angles to guide the medium to move in the same direction as the film (13) wound around the outer surface of the drum (30).

[0103] Accordingly, the medium passing through the guide member (52) is wound and stored between the film (12) wound on the outer surface of the drum (30) and the continuously wound film (13) by the rotation of the drum (30).

[0104] Next, the operation of discharging the stored media to the outside using the media entry / exit device (10) is explained.

[0105] When the medium is discharged, as shown in FIG. 6, the drum (30) and the reel (40) each rotate in the opposite direction to the rotation direction during the storage operation. Then, the film (12) wound on the drum (30) is unwound and moved toward the reel (40) and wound onto the reel (40).

[0106] The medium stored between the film (12) wound on the outer surface of the drum (30) and the film being wound (actually the film being unwound) (13) moves forward together with the film (11).

[0107] The medium that has moved forward is transported along the upper surface of the guide member (52), the switching member (51), and the outer guide, and then enters the transport path (P1), and is then transported downward by the rotation of the rollers installed around the transport path (P1).

[0108] At this time, the branching section (60) is elastically supported by a spring member so that the tapered section (62) is positioned inclined toward the front side upward.

[0109] Accordingly, the medium transported to the bottom of the transport path (P1) enters the discharge path (P2) along the rear of the branch section (60), and moves along the discharge path (P2) by the rotational movement of the rollers provided on the discharge path (P2) and is discharged to the outside.

[0110] In this way, the media discharged to the outside may be moved to the media storage box or returned to the input box depending on the final acceptance or return decision result regarding the media received from the financial automation machine.

[0111] Meanwhile, if a jam occurs due to the media getting stuck or the film (11) getting tangled during the process of receiving and discharging the media as described above, the operator can open the upper cover (21) and the front cover (22) as shown in FIG. 2 to easily perform maintenance work around the transport path (P1).

[0112] And the operator can efficiently perform maintenance work by rotating the drum (30) by rotating the first operating lever (62) or by rotating the second operating lever (72) to rotate the multiple pairs of rollers (71).

[0113] Although the invention made by the inventors has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof.

[0114] The present invention is applied to a media entry / exit device technology that can store or discharge a medium using a pair of films wound on both sides of a rotating drum, and can guide the stored or discharged medium to move accurately.
