Description

Technical Field

[0001] The invention relates to the technical field of money counting machines, and more particularly to a vertical money counting machine. Background Art

[0002] Vertical banknote counters are usually composed of a housing, a banknote twisting mechanism, a banknote feeding channel, a counting and counterfeit detection mechanism, a banknote dispensing mechanism, and a control circuit. The banknote twisting mechanism is responsible for conveying the randomly stacked banknotes to the banknote feeding channel in an orderly manner and sending them to the counting and counterfeit detection link. Here, advanced sensor technologies such as ultraviolet light, infrared light, and magnetic sensors are used to identify the authenticity of banknotes and count them accurately. Subsequently, qualified banknotes are neatly delivered by the banknote dispensing mechanism.

[0003] However, in actual use, the problem of money jam has always troubled users. In a vertical banknote counter, due to the design of its vertical structure, the banknote will turn and enter the banknote feeding channel under the drive of the banknote twisting mechanism. When the banknote is wrinkled, damaged, taped or too wet, it is very easy to be blocked at this turning position and cannot move forward smoothly. The main reason is that there is no good transition between the banknote and the channel wall at this turning position, and the friction resistance becomes larger, resulting in banknote jam. At present, once the banknote jam occurs at the above position, the only way to solve it is to open the back cover of the banknote counter and manually remove the jammed banknote. However, this operation method has many disadvantages. On the one hand, the back cover opening structure design of the banknote counter is often limited in precision. For example, the channel opening device of the banknote counter disclosed by the publication number CN220137706U has a channel plate that cooperates with the back cover, and the frequent opening and closing of the back cover easily causes the connection part to loosen and deform, causing the originally precise channel plate to have displacement deviation, thereby affecting the smoothness of banknote transmission and increasing the probability of subsequent banknote jam. On the other hand, it is difficult to completely avoid touch interference on internal components during each manual banknote withdrawal process. Over time, these subtle impacts accumulate, further damaging the structural accuracy of the banknote counter, making banknote jams more frequent, forming a vicious circle. Banknote jams not only reduce banknote counting efficiency, but may also cause additional damage to banknotes, causing great inconvenience to users.

[0004] In summary, the existing vertical banknote counting machines are in urgent need of improvement to enhance the reliability and stability of the equipment and meet the growing demand for cash processing. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a vertical banknote counter, which optimizes the internal structure design of the banknote counter so that banknotes are not easily jammed.

[0006] To achieve the above object, the present invention provides the following technical solutions: A vertical banknote counter includes a bill inlet plate, a bill outlet plate installed in the banknote counter, and a channel plate connecting the bill inlet plate and the bill outlet plate. The end of the channel plate is hinged to the bill outlet plate, and a hook is provided at the starting end of the bill outlet plate. A limit post is provided on the housing of the banknote counter, and the hook is matched with the limit post to fix or separate the starting end of the channel plate; a connecting portion is provided at the starting end of the channel plate, the connecting portion is in contact with the note-rolling wheel, and a number of guiding ridges are provided on the connecting portion at intervals, and air grooves are provided on the guiding ridges.

[0007] The present invention is further provided as: One end of the air groove is set as an air inlet, and the other end is set as an air outlet. The air inlet is located on the side of the guiding ridge, and the air outlet is located above the guiding ridge.

[0008] The present invention is further provided as: The inner diameter of the air groove gradually becomes narrower from the air inlet to the air outlet.

[0009] The present invention is further provided as: A protective cover is further provided at the starting end of the channel plate. The protective cover covers the outside of the connecting portion. The protective cover is provided with a collection cavity and a filter layer from outside to inside. The filter layer is used to block dust and impurities, and the collection cavity is used to collect the blocked dust and impurities.

[0010] The present invention is further provided as: A cleaning roller group is provided above the bill inlet plate. The cleaning roller group includes an adsorption roller, a peeling roller, and a guiding cavity. The adsorption roller is in contact with the note-rolling wheel. When the note-rolling wheel drives the banknote, the adsorption roller closely adheres to the surface of the banknote; the peeling roller is in contact with the adsorption roller and rotates in the opposite direction. The guiding cavity is provided below the peeling roller and is communicated with the collection cavity.

[0011] The present invention is further provided as: A flexible sealing strip is provided at the end of the guiding cavity, and the flexible sealing strip abuts against the end of the collection cavity.

[0012] The present invention is further provided as: A rotating shaft with a torsion spring structure is provided at the starting end of the channel plate. The hooks are fixedly provided on both sides of the rotating shaft, and the protective cover is fixedly provided on the rotating shaft.

[0013] The present invention is further provided as: Installation grooves are provided on both sides of the protective cover. The filter layer is slidably matched with the installation grooves. Protrusions are provided at the bottom of the installation grooves, and corresponding grooves are provided at the bottom of the filter layer. The protrusions are clamped with the grooves to realize the detachable connection between the filter layer and the installation grooves.

[0014] The present invention is further provided as: The limit post is provided on the outer shell of the banknote counter, and a bearing sleeve is provided on the limit post.

[0015] The present invention is further configured such that: a rotatable air supply roller is further provided on one side of the channel plate, and the air supply roller is used to supply air to one side of the air passage.

[0016] In summary, the present invention has the following beneficial effects:

[0017] Compared with the prior art, the present invention provides a connection part on the channel plate, and spaced guiding ridges are provided on the connection part. Due to the spaced arrangement, the contact area between the banknote and the guiding ridges is reduced, the frictional resistance is lowered. At the same time, air passages are formed between the guiding ridges; when the banknote is rapidly conveyed, the air between the banknote and the connection part is rapidly carried away, generating the Bernoulli effect, causing the banknote to adhere to the connection part, increasing the frictional resistance. The design of the air passages allows air to smoothly enter, thereby reducing the pressure difference of the Bernoulli effect and preventing banknote jamming caused by the increase in frictional resistance. Further, an air groove is provided, through which air can further enter between the guiding ridges and the banknote, minimizing the resistance of the banknote to the greatest extent and preventing banknote jamming.

[0018] Meanwhile, the present invention further provides a cleaning roller set to ensure that there are no impurities such as dust on the side of the banknote in contact with the channel plate, ensuring low friction between the banknote and one side of the channel plate and preventing the accumulation of impurities such as dust in the air groove; the present invention also provides a protective cover, which is used to filter dust in the air and ensure that dust is not easily accumulated in the air groove. And due to the Bernoulli principle, the air groove guides the air in the protective cover between the guiding ridges and the banknote, generating a slight negative pressure in the protective cover, which can assist the cleaning roller set to guide the dust on the banknote into the collection cavity.

[0019] The internal channel structure of the vertical banknote counter of the present invention is reasonably designed and not prone to banknote jamming. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This embodiment discloses a vertical currency detector, as Figure 1-8As shown in the figure, it includes a bill feeding plate 1, a bill discharging plate 2 installed in a banknote counter, and a channel plate 3 connecting the bill feeding plate 1 and the bill discharging plate 2. Among them, the bill feeding plate 1 is used to place banknotes, and is followed by a banknote twisting wheel to realize bill feeding; several banknote detection elements and counting elements are provided on the channel plate 3, which are used for banknote verification and counting during the banknote conveying process, and are the same as the prior art; the bill discharging plate 2 is used to carry the sent banknotes, and is followed by a banknote separating wheel to separate the banknotes. The end of the channel plate 3 of the present invention is hinged to the bill discharging plate 2, a hook 301 is provided at the starting end of the bill discharging plate, and a limit post 302 is provided on the housing of the banknote counter. The hook 301 and the limit post 302 cooperate to fix or separate the starting end of the channel plate 3. Among them, the hook 301 has an arc-shaped hook part, which can well wrap the limit post 302, making the cooperation accuracy better, and it is not linked with the rear cover of the banknote counter, the structure is relatively simple, the reliability is stronger, and the cooperation of the two is not easy to loosen and cause errors after long-term use, and the service life is long. When fixed at the starting end, the banknote conveying channel can work normally. When separated, the channel plate 3 is opened, and the inside can be repaired or the jammed banknotes in the channel can be processed. An engaging part 4 is provided at the starting end of the channel plate 3 of the present invention. The engaging part 4 abuts against the banknote twisting wheel. A plurality of guiding ribs 5 are arranged at intervals on the engaging part 4, and air grooves 6 are provided on the guiding ribs 5. The banknote twisting wheel 12 has a protruding toothed rubber. When the banknote twisting wheel rotates and its toothed rubber passes over the banknote, it will drive the banknote to enter the channel plate 3 from the bill feeding plate 1. Due to the arrangement of the engaging part 4 and the guiding ribs 5, when the banknote is bent and folded here, it can be smoothly guided and is not easy to jam. Specifically, the guiding ribs 5 are arranged at intervals. On the one hand, it can reduce the contact area between the banknote and the engaging part 4, thereby reducing the frictional resistance to a certain extent; on the other hand, it forms an air channel, and the air channel can connect the gap between the guiding ribs and the banknote with the outside, so that air can enter from the air channel, avoiding the banknote being tightly attached to the surface of the guiding rib due to the Bernoulli effect. Therefore, the design of the guiding ribs 5 of the present invention can well solve the problem of banknote jamming when the banknote is bent and folded driven by the banknote twisting wheel.

[0031] As a preferred embodiment, air grooves 6 can be further provided on the guiding ribs. One end of the air groove 6 is set as an air inlet 601, and the other end is set as an air outlet 602. The air inlet 601 is located on the side surface of the guiding rib 5, and the air outlet 602 is located above the guiding rib 5. The inner diameter of the air groove 6 gradually becomes narrower from the air inlet 601 to the air outlet 602. Refer to Figure 3 、 Figure 6-7 , when the banknote 10 is driven by the banknote twisting wheel, due to the very fast banknote conveying speed and the very small gap between the banknote engaging part and the guiding rib, the banknote will drive the air in the gap to move quickly. Due to the Bernoulli effect, the gas flow rate is fast and the pressure is low, so that a slight negative pressure is generated in the gap, and the side of the banknote 10 facing the banknote twisting wheel ( Figure 6On the left side in it), the space is large, the gas flow rate is less affected, and the air pressure is relatively high. Therefore, the banknote 10 will be squeezed towards the side of the guiding edge 4, resulting in an increase in frictional resistance and thus prone to banknote jamming. After the air channel is provided, the squeezing of the banknote is reduced. However, at the position corresponding to the guiding edge, there is still partial squeezing. Therefore, by further providing air grooves, referring to Figure 7 In the air flow direction 11 in it, the air is also affected by the negative pressure and easily enters between the banknote 10 and the guiding edge 5 along the air groove 6, balancing the generated negative pressure, and to a certain extent, preventing the banknote 10 from being squeezed on the guiding edge 5, further avoiding frictional resistance and making the banknote 10 less prone to banknote jamming. At the same time, the change in the inner diameter of the air groove 6 forms a shape similar to a flared opening, which can expand the air intake area and reduce the air intake resistance.

[0032] In a further setting, a protective cover 7 is preferably provided at the starting end of the channel plate 3. The protective cover 7 covers the outside of the connecting part 4. The protective cover 7 is provided with a collection cavity 701 and a filter layer 702 from outside to inside. The filter layer 702 is used to block dust and impurities, and the collection cavity 701 is used to collect the blocked dust and impurities. Through the above structural setting, the air entering the air groove 6 is filtered through the protective cover 7, preventing a large amount of dust from accumulating in the air groove 6 and causing the problem of blocking the air groove 6. At the same time, dust, impurities, etc. are blocked in the collection cavity 701 and can be centrally cleaned during subsequent cleaning, which is relatively convenient and fast.

[0033] Furthermore, in order to ensure the cleanliness of the banknote surface to avoid an increase in resistance and dust on the surface blocking the air groove 6, a cleaning roller set 8 is provided above the banknote feeding plate 2. The cleaning roller set 8 includes an adsorption roller 801, a peeling roller 802, and a guiding cavity 803. The adsorption roller 801 is in contact with the banknote twisting wheel. When the banknote twisting wheel drives the banknote, the adsorption roller 801 closely adheres to the banknote surface; the peeling roller 802 is in contact with the adsorption roller 801 and rotates in the opposite direction. The guiding cavity 803 is arranged below the peeling roller 802 and is communicated with the collection cavity. In this embodiment, the adsorption roller is set as a rubber adsorption roller or an electrostatic generation adsorption roller, and there is a gap of 1-3 mm between it and the banknote. The relatively close distance ensures the adsorption effect. The peeling roller 802 is set as a soft brush roller. If electrostatic generation adsorption is adopted, the roller is made of a conductive metal material. The principle of electrostatic generation can obtain high-voltage electricity by using a small boost module, combined with capacitive coupling induction, so that static electricity is generated on the electrostatic adsorption roller, or directly use an existing small electrostatic generator to connect to the electrostatic adsorption roller to generate static electricity on its surface; the rubber adsorption roller relies on its physical properties to electrostatically adsorb dust. Thus, referring to Figure 8, when the bill feeding wheel drives the conveyance of banknotes, the adsorption roller can adsorb dust and the like attached to the surface thereof, making the contact of the subsequent connection part of the banknote and the channel plate smoother and reducing the resistance; then as the adsorption roller 801 continues to rotate, after adsorbing a certain amount of dust, the adsorption force decreases, and the surface with dust comes into contact with the peeling roller 802, which is made of soft nylon or polyester fiber and has a brush structure on the surface. Since the acting force on the dust is relatively large, part of the dust will be peeled off from the adsorption roller 801 and thus be driven into the guiding cavity. The guiding cavity 803 is communicated with the collecting cavity 701, and the collecting cavity 701 is in turn communicated with the air groove. And during the banknote conveying process, affected by the air pressure, the air in the collecting cavity 701 is guided to the air groove and enters the gap between the banknote and the guiding edge. There is always a slightly negative pressure in the collecting cavity 701, which can promote the dust peeled off in the guiding cavity 803 to fall into the collecting cavity. Therefore, only the collecting cavity needs to be cleaned for daily cleaning and maintenance. Only when the adsorption and peeling effects of the adsorption roller and the peeling roller decrease significantly after a long time of use, the overall cleaning is carried out, effectively improving the efficiency of daily maintenance.

[0034] Furthermore, a flexible sealing strip 8031 is arranged at the end of the guiding cavity 803, and the flexible sealing strip 8031 is arranged in contact with the end of the collecting cavity 701. The guiding cavity 803 and the collecting cavity 701 are in contact with each other after being installed in place, and a certain seal is formed through the flexible sealing strip 8031. The main function is to further improve the falling of the peeled dust into the collecting cavity and prevent the dust from flying inside the bill counter. In terms of air intake, air enters the bill counter from the rear cover of the bill counter (provided with air vents), then enters the collecting cavity through the circular through holes on the outer wall of the collecting cavity, and then passes through the filter screen and enters the position of the inner channel plate 3. Therefore, the cleaning roller group and the protective cover of the present invention constitute a relatively sealed environment, ensuring that dust and impurities will not fly inside the bill counter but will be blocked in the collecting cavity.

[0035] Furthermore, referring to Figure 4-5 , a rotating shaft 9 with a torsion spring structure is arranged at the starting end of the channel plate 3. Hook-shaped catches 301 are fixedly arranged on both sides of the rotating shaft 9, and the protective cover 7 is fixedly arranged at the middle position of the rotating shaft 9. Through the above structure, the rotating shaft 9 plays a bearing role. When disassembling, a person can operate the actuating member 13 to drive the rotating shaft 9 to rotate, so that the hook-shaped catches 301 are separated from the limiting posts 302, and then the channel plate 3 can be opened downward. At this time, the protective cover 7 that was originally in contact with the guiding cavity upward faces the outside, and a person can clean the collecting cavity inside the protective cover, which is very convenient. After buckling back the hook-shaped catches 301, the protective cover 7 can be in contact and cooperate with the guiding cavity again. And the hook-shaped catch and limiting post structure set in the present invention has higher precision compared with the traditional opening method linked to the rear cover, is less likely to loosen and shift, ensures the reliability of the structure, and is not likely to cause bill jamming due to errors caused by structural looseness.

[0036] Furthermore, mounting grooves are provided on both sides of the protective cover 7. The filter screen layer 702 is slidably engaged with the mounting grooves. Protrusions are provided at the bottom of the mounting grooves, and corresponding grooves are provided at the bottom of the filter screen layer 702. The protrusions are snap-fitted with the grooves to achieve detachable connection between the filter screen layer and the mounting grooves. Thus, while cleaning the collection chamber, the filter screen layer 702 can also be removed for cleaning or replacement.

[0037] Furthermore, the limiting posts 302 are arranged on the outer shell of the banknote counter. Bearing sleeves are arranged on the limiting posts 302. When the hook 301 and the limiting posts 302 are installed through the bearing sleeves, the smoothness is increased. That is, the hook can be pushed, and the hook will drive the bearing sleeve to rotate, and then naturally hook the limiting posts, making the disassembly and assembly convenient and fast.

[0038] As a further embodiment, referring to Figure 8 , a rotatable air supply roller 16 is further arranged on one side of the channel plate 3. The air supply roller 16 is used to supply air to the airway 50 side. The rotating shaft of the air supply roller 16 can be simply driven in cooperation with the rotating shaft of the banknote twisting wheel through a pulley and a belt (not shown in the figure). A plurality of fan blades are arranged on the circumferential side of the air supply roller 16. Thus, when rotating, the air flow to positions such as the guiding edges, airways, and air grooves of the channel plate 3 can be strengthened, further reducing the pressure difference on both sides of the banknote and avoiding banknote jamming. Moreover, through active air supply, the air supply roller not only strengthens the pressure balance on both sides of the banknote, but also generates a stronger negative pressure area inside the protective cover, ensuring that the dust peeled off in the guiding chamber 803 can better fall into the collection chamber.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
