Example one

As shown in fig. 1, an embodiment of the present invention provides a long-roller type banknote dispensing roller type sensitive detection mechanism using a U-shaped sensor device, including: the detection device comprises a detection bracket 1, a return spring 2, a roller (in the embodiment, a long roller 5), a roller swing frame (in the embodiment, a first roller swing frame 6), a U-shaped sensor 7 and a detection swing sheet 11.

As shown in fig. 4, the first roller swing frame 6 is fixedly provided with a detection swing piece 11; as shown in fig. 3, the U-shaped sensor 7 is fixedly mounted on the upper part of the detection bracket 1 through screws; as shown in fig. 5, 7 and 9, the banknote-dispensing roller type sensitive detection mechanism is integrally mounted on the edge of the receiving platform 41 of the banknote-dispensing device 100 for detecting banknotes.

When no bank note passes through, the detection swinging piece 11 is positioned in the gap in the middle of the U-shaped sensor 7, and when the bank note passes through, the detection swinging piece 11 is separated from the gap in the middle of the U-shaped sensor 7; the U-shaped sensor 7 is used for determining whether the banknotes pass through currently or not according to the position of the swinging piece 11.

As shown in fig. 4, a spring mounting hole 12 is formed in the middle of the first roller swing frame 6; as shown in fig. 3, the detection support 1 is provided with a spring hole 13; two ends of the reset spring 2 are respectively mounted in the spring hole 13 and the spring mounting hole 12; the return spring 2 is used to return the first roller swing frame 6 when a banknote is taken out.

As shown in fig. 3, the detection support 1 is further symmetrically provided with a second limiting arm 32 and a third limiting arm 33; the second and third limiting arms 32 and 33 are used together to limit the rotation angle of the roller swing frame (counterclockwise rotation when viewed from the left) when a banknote passes through, so as to avoid an excessive rotation angle of the roller swing frame.

As shown in fig. 1, the banknote discharging roller type sensitive detection mechanism using the U-shaped sensor further includes: a first rotating shaft 3 and a second rotating shaft 4.

As shown in fig. 1 and 3, the detection support 1 is further symmetrically provided with rotation mounting holes 34, the first rotating shaft 3 penetrates through the first roller swing frame 6, and two ends of the first rotating shaft 3 are disposed in the rotation mounting holes 34; the first rotating shaft 3 is used for connecting the roller swing bracket and the detection bracket 1 through the rotating mounting hole 34; the first roller swing frame 6 rotates along the first rotation axis 3.

As shown in fig. 1 and 4, the first roller swing frame 6 is symmetrically provided with cantilevers 16, a rotation shaft hole 14 is provided at a lower portion of each cantilever 16, the second rotation shaft 4 penetrates through the long roller 5, two ends of the second rotation shaft 4 are respectively provided in the rotation shaft holes 14, the second rotation shaft 4 is used for connecting the long roller 5 and the cantilevers 16, and the rollers can rotate around the second rotation shaft. The arrangement can realize the rolling friction between the long roller 5 and the bills and the bearing platform 41, reduce the friction force and protect the bills.

As shown in fig. 4, the first roller swing frame 6 is further provided with a spring mounting hole 12, a symmetrical cantilever 16 and a detection swing piece 11, and a spring hole 14 is provided at the lower part of the cantilever 16.

As shown in fig. 5, the sensing mechanism is mounted at the edge of the dispensing apparatus 100, and the long roller sensing mechanism of this embodiment may span over the banknote feeding follower shaft 17.

As shown in fig. 7, the detection mechanism is mounted on the receiving platform 41 near the withdrawal port; the left side of the receiving platform 41 is the outlet of the banknote, also called the banknote start 42, and the right side is equipped with the entire sensing mechanism.

One end of the reset spring 2 is hooked in a spring hole 13 of the detection support 1, the other end of the reset spring is hooked in a spring mounting hole 12 on the roller swing frame, and the reset spring 2 is used for enabling the first roller swing frame 6 to reset after the bank note is taken out, even if the roller is attached to the bearing platform 41, the first roller swing frame 6 rotates clockwise (the visual angle of fig. 7) to reset.

The working process of the long-roller type banknote outlet roller type sensitive detection mechanism adopting the U-shaped sensor device in the embodiment is realized according to the following principle:

as shown in fig. 7, when a banknote is fed from the banknote start end 42 of the banknote dispensing apparatus 100 to the roller, the trigger roller is lifted up counterclockwise (counterclockwise from the perspective of fig. 7), so that the detection flap 11 rotates counterclockwise, and the detection flap 11 is detected to be out of the sensing range of the U-shaped sensor 7 (as shown in fig. 8, which is a schematic diagram of the detection flap being out of the U-shaped sensor), at this time, the U-shaped sensor 7 senses the change, and then it is determined that there is a banknote passing through at this time.

In this process, the second limiting arm 32 and the third limiting arm 33 are used together to limit the counterclockwise rotation angle (i.e. the view angle in fig. 7 and 8) of the roller swing frame when a bill passes through, i.e. to avoid the roller swing frame from rotating too much.

In this process, there is rolling friction between the banknote and the rollers.

When the bank note is taken away, the roller swing frame returns to the original state clockwise (i.e. the viewing angles of fig. 7 and 8) under the action of the return spring 2, so that the detection swing piece 11 rotates clockwise and then returns to the sensing range of the U-shaped sensor 7 (as shown in fig. 6, the schematic diagram of the sensing swing piece reaching the sensing range of the U-shaped sensor), at this time, the U-shaped sensor 7 senses the change, and then judges that the bank note is taken away at this time, and the bank note is currently in a no-bank-note state.

When the bank note is recovered, namely in fig. 7, when the bank note moves from right to left, rolling friction exists between the bank note and the roller, so that the phenomenon of 'jamming' is avoided, and the bank note is more conveniently recovered.

Preferably, it is possible to decide whether to use the space roller type structure or the long roller type structure according to the user's needs, and if the need is to go across the driven shaft 17, the long roller type structure is selected as shown in fig. 5; in contrast, a spacer roller type configuration is shown in FIG. 9.

Whether the short roller interval type or the long roller type is adopted, the length of the cantilever 16 can be adjusted according to the actual installation position.

The existing detection mechanism utilizing the correlation sensor cannot span the driven shaft 17, namely has similar functions with an interval roller type structure, cannot meet the diversified requirements of customers, is easy to deposit dust to cause sensitivity reduction and inaccurate detection.

The beneficial effects of the embodiment are as follows:

the detection structure adopts the U-shaped sensor to detect the bank note, the U-shaped sensor can avoid the sensing error caused by dust deposition, and the bank note can be detected more accurately; the detection structure does not depend on a bearing platform, can adjust the installation position as required, and can select roller styles according to the condition of a driven shaft; the rolling friction is formed between the roller and the bank note, so that the damage of the friction force to the bank note can be reduced, and the phenomenon of 'jamming' can be avoided; the limiting arm in the detection mechanism can avoid overlarge rotation angle of the roller swing frame; the length of the cantilever in the detection mechanism can be adjusted so as to be suitable for financial equipment with different specifications.
