Description

Technical Field

[0001] The utility model relates to the field of banking machines, in particular to a medium conveying structure applied to split banking machines. Background Art

[0002] Bank machines are composed of a movement and a panel. Traditional bank machines usually have the movement and panel integrated together as a complete device, which results in a large workload for operation and maintenance. The movement of each device needs to be processed, including the loading and removal of cash, as well as the status and removal of bank cards.

[0003] In order to solve the above problems, some existing technologies attempt to separate the panels of the movement. For example, Chinese patent CN111932797A discloses a solution for separating the panels of the movement. Since the working efficiency of the panel is subject to the operating efficiency of the user, fewer movements can be used to serve more panels. At this time, the operation and maintenance work only needs to be carried out on a smaller number of movements, and the workload is greatly reduced.

[0004] In the prior art, during the transfer of banknotes, after the robot arm clamps the banknotes from the movement and transfers them to the banknote box on the panel, the banknotes need to be inserted into the spring pieces of the banknote box, which is difficult and has a high failure rate.

[0048] The following will describe in detail some embodiments of the present utility model with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0049] A medium conveying structure applied to a split-type banking machine, as Figure 1 shown, includes:

[0050] One or more cores 1, wherein at least one core 1 is a currency supply core 1 for providing banknotes;

[0051] One or more panels 2, wherein at least one panel 2 includes a banknote interaction mechanism;

[0052] The first robotic arm 3 is used to clamp and transfer the banknotes in the currency supply module 1 to the banknote interaction mechanism;

[0053] As Figure 2 shown, the banknote interaction mechanism includes a banknote pickup slot, a first banknote cassette, and a banknote cassette track 2-2. The first end of the banknote cassette track 2-2 is located in the banknote pickup slot, and the second end is disposed near the module 1 side. The bottom of the first banknote cassette is provided with a slider that cooperates with the banknote cassette track 2-2. When the first banknote cassette slides along the banknote cassette track 2-2 to the second end, the first robotic arm 3 places the banknote in the first banknote cassette. When the first banknote cassette slides along the banknote cassette track 2-2 to the first end, it is located in the banknote pickup slot for the user to pick up the banknote.

[0054] A movable first banknote cassette is adopted, so that when the first banknote cassette moves to the outside of the panel 2, banknote loading can be performed, thereby reducing the difficulty. In addition, there is no need to control the robotic arm to insert the banknote into the elastic slot.

[0055] Specifically, in almost all embodiments, the module can adopt a completely existing module, for example, in the same manner as in Chinese Patent CN111932797A. The panel can also generally adopt an existing panel, with the difference being that the first banknote cassette is improved. In most embodiments, the first banknote cassette includes:

[0056] A cassette body 2-1;

[0057] An elastic clamping unit 2-3, disposed inside the cassette body 2-1;

[0058] An electric cylinder 2-4 and a movable clamping unit 2-6, both disposed on the cassette body 2-1. The movable clamping unit 2-6 is connected to the output end of the electric cylinder 2-4 and moves towards the elastic clamping unit 2-3 under the action of the output end of the electric cylinder 2-4;

[0059] A clamping controller, connected to the electric cylinder 2-4, for controlling the operation of the electric cylinder 2-4.

[0060] By using the elastic clamping unit 2-3, the electric cylinder 2-4, and the movable clamping unit 2-6, the banknotes in the cassette body 2-1 can be assisted in clamping, reducing the accuracy requirements for the first robotic arm 3. The movable clamping unit 2-6 can provide stable clamping for the banknotes.

[0061] Generally, the elastic clamping member includes an elastic connecting member and a first clamping member. As shown in the figure, the root of the first clamping member is fixed to the bottom of the inner wall of the cassette body 2-1 through the elastic connecting member;

[0062] The moving clamping unit 2-6 includes a rigid connecting member and a second clamping member. The second clamping member is connected to the output end of the electric cylinder 2-4 through the rigid connecting member, and the projection area of the rigid connecting member in the first plane is completely covered by the projection area of the second clamping member in the first plane, where the first plane is perpendicular to the telescopic direction of the electric cylinder 2-4;

[0063] The overlapping part of the projection areas of the first clamping member and the second clamping member in the first plane is greater than 80%. Specifically, it is required that the ratio of the overlapping part to the projection area of the first clamping member in the first plane is greater than 80%, and the ratio of the overlapping part to the projection area of the second clamping member in the first plane is also greater than 80%. Of course, in this embodiment, when the first clamping member is in the natural state, as Figure 5 shown, the two completely overlap

[0064] Especially, as Figure 3 shown, there is no overlap between the projection areas of the elastic connecting member and the first clamping member in the first plane. In this way, when the first clamping member receives the pressure generated by the electric cylinder driving the second clamping member, it can bend towards the side close to the panel, so that when the thickness of the banknotes is different due to different numbers of banknotes, an elastic redundant space can be provided.

[0065] In some embodiments, a banknote gripper for gripping banknotes is provided on the first robotic arm 3. The banknote gripper is in a mountain shape, as Figure 4 shown, and hollow slots 2-3-1 for inserting the mountain-shaped protrusions of the banknote gripper are provided on both the first clamping member and the second clamping member.

[0066] During the process of the banknote gripper placing the banknotes into the first banknote box, when the banknote gripper moves to the lowest point relative to the first banknote box, the projection area of the banknote gripper in the first plane has no overlap with the projection areas of the first clamping member and the second clamping member in the first plane, and the overlapping part of the projection line segment of the banknote gripper in the vertical direction and the projection line segments of the first clamping member and the second clamping member in the vertical direction exceeds 80%.

[0067] As Figure 6 shown, the clamping controller includes a first light emitter, a first light receiver 2-5, a second light receiver D1, a first relay K1, a second relay K2, a main relay K3, and a low-voltage DC power supply VCC.

[0068] The first light emitter and the first light receiver 2-5 are respectively arranged on two opposite inner side walls of the box body 2-1 to form a first pair of optocouplers. The first light emitter is arranged opposite to the first light receiver 2-5, and the first light emitter passes through the hollow slots 2-3-1 of the first clamping member and the second clamping member and is received by the first light receiver 2-5.

[0069] The second optical receiver D1 is provided at the bottom of the box body 2-1, and a second optical transmitter that forms a second pair of optical couplers with the second optical receiver D1 is provided in the banknote taking slot. When the first banknote cassette slides along the banknote cassette track 2-2 to the first end, the second optical receiver D1 receives the light emitted by the second optical transmitter and conducts;

[0070] The first optical receiver 2-5 and the coil of the first relay K1 are connected in series. The second optical receiver D1 is connected in series with the second relay K2. The common contact of the first relay K1 is connected to the positive pole of the low-voltage DC power supply VCC, the normally closed contact is connected to the common contact of the second relay K2, and the normally closed contact of the second relay K2 is connected to one end of the coil of the main relay K3. The other end of the coil of the main relay K3 is connected to the negative pole of the low-voltage DC power supply VCC through the first current-limiting resistor R3. The normally open contact of the main relay K3 is connected to the positive pole of the low-voltage DC power supply VCC, and the normally open contact is connected to the positive power supply of the electric cylinder 2-4. The negative power supply of the electric cylinder 2-4 is connected to the negative pole of the low-voltage DC power supply VCC.

[0071] Both the first optical receiver 2-5 and the second optical receiver D1 are photosensitive diodes. When the first banknote cassette is not in the banknote taking slot, the second optical receiver D1 is in the off state. At this time, the coil of the second relay K1 is not energized, and its normally closed contact is in the on state. At this time, when there is no banknote, the first optical receiver 2-5 is in the on state, the coil of the first relay K1 is energized, and the normally closed contact is in the off state. At this time, the coil of the main relay K3 is not energized, and the normally closed contact is in the off state, and the electric cylinder does not work. When a banknote is put in, the first optical receiver 2-5 is in the off state, the coil of the first relay K1 is not energized, and the normally closed contact is in the closed state. At this time, the coil of the main relay K3 is energized, and the normally closed contact is in the closed state, and the electric cylinder works. The specific instruction table is shown in Table 1:

[0072] Table 1

[0073]

[0074] In Table 1, 1 indicates suction, and 0 indicates non-suction. It can be seen that only when the first banknote cassette is not in the banknote taking slot and a banknote is put in, the electric cylinder will work to clamp the banknote.

[0075] In almost all embodiments, the banknote taking slot can adopt the same form as the existing one, and the user can reach out to take the banknote.

[0076] In addition, in some embodiments, a second current-limiting resistor R4 is provided between the negative power supply of the electric cylinder 2-4 and the negative pole of the low-voltage DC power supply VCC. Similarly, a third current-limiting resistor R1 is also connected in series with the coil of the first relay K1, and a fourth current-limiting resistor R2 is also connected in series with the coil of the second relay K2.

[0077] In addition, in other embodiments, similar to the prior art, the panel 2 further includes a material medium interaction mechanism, and the conveying structure further includes a second robotic arm and a material medium channel. A plurality of material medium channels are provided and correspond to each material medium interaction mechanism one by one. The second robotic arm is used to transfer the material medium from the first movement 1 to the entrance of the material medium channel, and the output end of the material medium channel is communicated with the material medium interaction mechanism.
