Technical Field

[0001] The present invention relates to the technical field of self-service teller machines, in particular to a banknote conveying device and electronic equipment. Background Art

[0002] With the development of economic and financial electronic services, safe, reliable, and easy-to-use ATMs (Automated Teller Machines) have become widely used. ATMs offer customers 24 / 7 access to financial services such as deposits, withdrawals, and transfers, bringing convenience while reducing operating costs. ATMs are typically equipped with a banknote transport mechanism, whose primary function is to transfer banknotes deposited by customers into the cash drawer, or to receive instructions from the device to transfer banknotes from the cash drawer to customers.

[0003] The banknote conveying device usually needs to turn several times to complete the process of conveying banknotes. In the traditional structure, a synchronous belt is usually used to envelop the path of banknotes from the banknote sorting mechanism to the banknote dispensing mechanism, and a set of pulleys is added at the connection between the banknote sorting mechanism and the banknote dispensing mechanism. This structure not only takes up space, increases the motor load and transmission power loss; but also because the banknotes are subjected to different tensions at the head and tail ends when entering the banknote dispensing mechanism from the banknote sorting mechanism, the synchronous belt of the banknote dispensing mechanism has a large tension and a fast speed. When one end of the banknote enters first, the tilt angle will increase. The tilt of one or more banknotes will cause the banknotes to get stuck, thereby causing machine failure. Therefore, it is necessary to provide a new banknote conveying device to improve the above problems. Summary of the Invention

[0016] Preferably, the sliding wheel group includes a driven wheel and a driving wheel, the driven wheel is in contact with the transmission belt, and the driving wheel is in contact with the banknote pressing wheel group.

[0017] Preferably, a bearing is provided in the driven wheel.

[0018] In addition, to achieve the above-mentioned purpose, the present invention also discloses an electronic device, including the above-mentioned banknote conveying device.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the banknote separating mechanism cooperates to separate the banknotes one by one, and the banknote digging wheel rotates to drive the banknotes into the banknote transmission channel.

Through the above design, the banknote will not be pulled by the banknote dispensing mechanism before it is completely separated from the banknote sorting mechanism, causing the banknote to deflect, thus avoiding the problem of banknote jamming and malfunction caused by banknote deflection.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 The banknote conveying device in one embodiment of the present invention includes a banknote sorting mechanism 1, a banknote dispensing mechanism 2, a conveyor belt 3, at least one conveying wheel set 4, and a sliding wheel set 5 for steering and conveying banknotes, wherein:

[0030] The conveyor belt 3 cooperates with the banknote sorting mechanism 1 and the banknote dispensing mechanism 2 to transport banknotes;

[0031] The transmission belt 3 is arranged on the transmission wheel set 4, and the transmission wheel set 4 cooperates with the transmission belt 3 to perform power transmission;

[0032] The sliding wheel group 5 is provided between the banknote sorting mechanism 1 and the banknote dispensing mechanism 2, and the sliding wheel group 5 is in contact with the conveyor belt 3 to generate a conveying force F1 on the banknotes to clamp and convey the banknotes;

[0033] The banknote dispensing mechanism 2 includes a banknote pressing wheel group 21, which contacts and cooperates with the sliding wheel group 5 to generate a conveying force F2 on the banknotes to clamp and convey the banknotes;

[0034] The banknote sorting mechanism 1 includes a pressing wheel 11 and a banknote scooping wheel group 13. The pressing wheel 11 and the banknote scooping wheel group 13 are in contact with each other to generate a conveying force F3 on the banknotes to clamp and convey the banknotes.

[0035] The conveying force F3 is greater than or equal to the sum of the conveying force F1 and the conveying force F2.

[0036] In one embodiment of the present invention, the conveying force refers to the friction force or clamping pressure acting on the surface of the banknote.

[0037] When working, the banknote separating mechanism 1 cooperates to separate the banknotes one by one, and the banknote digging wheel group 13 rotates to drive the banknotes into the banknote transmission channel. A pressure wheel 11 is provided next to the banknote digging wheel group 13. The pressure wheel 11 contacts and cooperates with the banknote digging wheel group 13, and generates a clamping force on the banknotes while rotating and pushing the banknotes. The thrust and the clamping force together constitute the transmission force F3; after the banknotes pass through the banknote digging wheel group 13, one end first enters the sliding wheel group 5, and the sliding wheel group 5 is driven by the transmission belt 3 to rotate, and the banknotes are rolled between the sliding wheel group 5 and the transmission belt 3, generating a transmission force F2 on the banknotes so as to clamp and transport the banknotes, but because the transmission force F2 is less than the transmission force F3, the transmission belt 3 and the banknotes are not in contact. The sliding wheel group 5 cannot pull the banknote, and the banknote is in a slipping state at the sliding wheel group 5. Therefore, the banknote still moves under the action of the transmission force F3, avoiding the sliding wheel group 5 and the transmission belt 3 pulling the banknote, causing the banknote to tilt or jam; until the banknote is transported to the banknote dispensing mechanism 2, the banknote pressing wheel group 21 in the banknote dispensing mechanism 2 cooperates with the sliding wheel group 5 to clamp and transport the banknote, forming the transmission force F1, but because the transmission force F3 is greater than or equal to the sum of the transmission force F1 and the transmission force F2, the banknote is still unable to be pulled at this time, preventing the banknote from tilting and causing the banknote to jam, until the end of the banknote is separated from the banknote sorting mechanism 1 and is no longer affected by the transmission force F3. Through the above design, the banknote will not be pulled by the banknote dispensing mechanism 2 before it completely leaves the banknote sorting mechanism 1, causing the banknote to deflect, thus avoiding the problem of banknote jamming and malfunction caused by banknote deflection.

[0038] More specifically, the banknote sorting mechanism 1 also includes a first bracket 18 and a second bracket 19 arranged at intervals from each other, the first bracket 18 is provided with a banknote sorting shaft 14 and a banknote sorting wheel group 15 arranged on the banknote sorting shaft 14, the second bracket 19 is provided with a banknote digging shaft 12, a banknote kicking shaft 16 and a banknote kicking wheel group 17 arranged on the banknote kicking shaft 16, the banknote digging wheel group 13 is arranged on the banknote digging shaft 12, the banknote sorting shaft 14, the banknote digging shaft 12 and the banknote kicking shaft 16 are all arranged in parallel and at intervals, and the banknote kicking wheel group 17 performs a rotation action to lift the banknotes and then roll them between the banknote digging wheel group 13 and the banknote sorting wheel group 15 and transport them, so that a banknote transmission channel is formed between the banknote digging wheel group 13, the banknote sorting wheel group 15 and the banknote kicking wheel group 17.

[0039] More specifically, the banknote scooping wheel group 13 includes a first banknote scooping wheel 131 and a second banknote scooping wheel 133. The first banknote scooping wheel 131 is provided with a banknote scooping portion 132, and the second banknote scooping wheel 133 is provided with a friction portion 134 along the circumferential surface. The banknote scooping portion 132 and the friction portion 134 are both made of rubber material to provide sufficient friction to prevent banknotes from slipping.

[0040] More specifically, the bill-kicking wheel assembly 17 includes a plurality of bill-kicking wheels 171 . The bill-kicking wheels 171 are arranged in a staggered manner, and each bill-kicking wheel 171 is provided with a bill-kicking portion 172 .

[0041] More specifically, the banknote dispensing mechanism 2 further includes a mounting frame 22, the mounting frame 22 is provided with a connecting portion 221 adapted to the shape of the sliding wheel group 5, the banknote pressing wheel group 21 is provided on the mounting frame 22, and the banknote pressing wheel group 21 contacts and cooperates with the sliding wheel group 5 after passing through the mounting frame 22.

[0042] More specifically, the rotation speed of the bill-digging wheel group 13 is lower than the rotation speed of the conveyor belt 3. When the banknotes are completely separated from the banknote sorting mechanism 1, the speed of the conveyor belt 3 is obtained. Since the speed of the conveyor belt 3 is higher than the speed of the bill-digging wheel 12, and there is a distance between the banknotes, the previous banknote will run a distance ahead of the next banknote, thereby widening the distance between the banknotes and avoiding problems such as banknote jamming and malfunction caused by interference and obstruction between the banknotes.

[0043] More specifically, the sliding wheel set 5 includes a driven wheel 51 and a driving wheel 52 . The driven wheel 51 is in contact with the transmission belt 3 , and the driving wheel 52 is in contact with the banknote pressing wheel set 21 .
