Description

Technical Field

[0001] The invention relates to the technical field of banknote counting and separation, and in particular to a banknote counting machine. Background Art

[0002] A money counting machine is a machine that integrates the functions of counting banknotes and anti-counterfeiting identification. Traditional money counting machines are composed of multiple parts such as the banknote twisting part, the banknote dispensing part, the banknote receiving part, the frame assembly, the motor, the transformer, the electronic circuit, etc. It has the characteristics of fast counting and accurate identification.

[0003] For paper money, traditional money counting machines are fully capable of counting the number of banknotes, but the currencies of some countries are not entirely paper money, but contain plastic materials. Their exterior is made of polypropylene plastic polymer, which is a mixture of plastic film and synthetic fiber. The function of the banknote twisting part is to twist out the banknotes to be counted one by one, wherein the banknote twisting rubber ring on the rotatable banknote twisting wheel twists away a banknote on the surface alone, separates the banknote on the surface from the banknote below, and realizes banknote separation. This process is repeated continuously to ensure accurate counting. Then the separated banknotes are sent to the counter and detection sensor of the banknote output part for counting and anti-counterfeiting. When the banknote twisting rubber ring rotates with the banknote twisting wheel and twists away the banknotes made of plastic polymer, the banknotes that conflict with the banknote twisting wheel will be moved away with it, and sliding friction will occur between the removed banknote and the adjacent banknote to the removed banknote, and the friction between the banknotes is likely to generate static electricity and accumulate, causing static electricity adsorption between the banknotes, and it is easy for two banknotes to be twisted away together due to static electricity adsorption between each other when twisting the banknotes.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Reference Figure 1 -Attached Fig.11 , a money counting machine, comprising:

[0042] A plurality of rollers 1 are arranged equidistantly around a circle and are capable of rotating about a virtual central axis;

[0043] A circular groove is coaxially provided inside the roller 1;

[0044] A rubber sleeve 2 is fixedly mounted on the inner wall of the circular groove, separating the circular groove to form a first area 3 and a second area 4 that are isolated from each other;

[0045] A plurality of first through grooves 5 and second through grooves 6, wherein the first through grooves 5 and the second through grooves 6 are connected to the first area 3 and the second area 4 respectively;

[0046] When separating banknotes, pressure is applied to the whole bundle of banknotes to make them move toward the virtual center axis between the multiple rollers 1 until they collide with any one of the rollers 1. Then the multiple rollers 1 rotate. During rotation, when the first slot 5 is close to the banknote, the first area 3 forms a negative pressure to absorb the banknote closest to the first slot 5.

[0047] Through the above technical solution, negative pressure attraction is used to separate adjacent banknotes in a whole pack of banknotes, so that adjacent banknotes do not slide relative to each other, thereby preventing the generation of static electricity and overcoming the problem of non-single banknotes being twisted away due to static attraction.

[0048] The money counting machine also includes:

[0049] Body 7;

[0050] A tank body 8 is provided on the machine body 7;

[0051] A display screen 9 is arranged on one side of the body 7;

[0052] The folding plate 10 is slidably arranged inside the groove body 8;

[0053] The compression spring 11 is arranged between the folding plate 10 and the groove body 8, and is connected to the folding plate 10 and the inner wall of the groove body 8 respectively;

[0054] A vertical rod 12 is vertically fixed inside the tank body 8;

[0055] The folding plate 10 has a transverse groove 13 adapted to the vertical rod 12 to facilitate the sliding of the folding plate 10. A whole banknote is fed onto the folding plate 10, and the compression spring 11 applies pressure to the whole banknote, so that the banknote contacts any roller 1.

[0056] A motor 14 is installed on the machine body 7, and the output end of the motor 14 is fixedly connected to a rotating shaft 15. The rotating shaft 15 is rotatably connected to the trough body 8. The central axis of the rotating shaft 15 is a virtual central axis between multiple roller shafts 1. The upper and lower parts of the rotating shaft 15 are fixedly connected with sleeve rings 16. The outer wall of the sleeve ring 16 is fixedly connected to multiple groups of connecting components, and each group of connecting components contains two connecting blocks 17. One end of the connecting block 17 is fixedly connected to the sleeve ring 16, and the other end is fixedly connected to the roller shaft 1.

[0057] The same group of connecting blocks 17 are rotatably connected to the rotating rod 18, and the rotating rod 18 passes through the roller shaft 1. The outer wall of the rotating rod 18 located inside the roller shaft 1 is fixedly sleeved with a cam 19, and the cam 19 has a protruding portion. A plurality of springs 20 are connected and arranged in the first area 3. When the protruding portion of the cam 19 rotates to contact the rubber sleeve 2, the rubber sleeve 2 is squeezed and deformed, so that the space in the first area 3 is correspondingly reduced, while the space in the second area 4 is correspondingly increased. When the protruding portion of the cam 19 rotates to move away from the rubber sleeve 2, the rubber sleeve 2 returns to its original state under its own elastic force and the elastic force of the spring 20, so that the space in the first area 3 is correspondingly increased, while the space in the second area 4 is correspondingly reduced. The increase in space generates negative pressure to form an adsorption effect.

[0058] The inner wall of the groove body 8 is fixedly connected to the first ring 21, which is composed of N and S poles. The top of the rotating rod 18 is fixedly connected to the second ring 22, which is composed of N and S poles. The second ring 22 is always in contact with the inner wall of the first ring 21.

[0059] The same group of connecting blocks 17 is also fixedly connected to a U-shaped frame 23, on which a counter and a detection sensor 24 are provided. The counter and the detection sensor 24 are connected in parallel, and a loop formed in parallel forms positive and negative poles 25 above the U-shaped frame 23. A metal conductive ring 26 is fixedly provided inside the circular groove, and the metal conductive ring 26 contacts the positive and negative poles 25 above the U-shaped frame 23, and the metal conductive ring 26 is connected to the live wire and the neutral wire of the wires inside the body 7.

[0060] Since one end of the first through slot 5 for adsorbing banknotes is an arc surface, part of the air enters the first area 3 through the first through slot 5 during adsorption, which sometimes causes insufficient suction force for adsorbing banknotes. Therefore, the following improvements are made:

[0061] A limit frame 27 is fixedly connected inside the first through groove 5. The limit shape formed by the limit frame 27 is spherical. An adaptive sphere 28 is arranged inside the limit frame 27. The sphere 28 has a small hole 29 arranged through it. When the negative pressure formed in the first area 3 remains unchanged, the speed of air entering the first area 3 when adsorbing banknotes is reduced, thereby correspondingly improving the adsorption effect on banknotes.

[0062] A fixing block 30 is fixedly connected inside the small hole 29, and a thin rope 31 is fixedly connected to the middle part of the fixing block 30. The other end of the thin rope 31 extends to the first area 3 and is connected to the rubber sleeve 2. When the rubber sleeve 2 is in its original state, the thin rope 31 is just stretched straight, so that the virtual central axis of the small hole 29 corresponds to the virtual central axis of the first through groove 5, which plays a role in straightening the sphere 28. The part of the sphere 28 facing the outside is made of a deformable rubber material to form a deformation part. When it collides with the banknote, pressure is applied to the deformed part of the sphere 28, so that the deformed part of the sphere 28 is squeezed, which further reduces the gap for air to enter the small hole 29, and further improves the adsorption effect on the banknote. At the same time, the deformed part of the sphere 28 that collides with the banknote will also follow the movement trajectory of the banknote due to friction and roll accordingly in the limit frame 27, thereby extending the adsorption time and achieving a better adsorption effect.

[0063] It should be noted that a fan-shaped shape can also be provided at the end of the small hole 29 close to the rubber sleeve 2, so as to expand the movement space of the thin rope 31 at the end of the small hole 29 close to the rubber sleeve 2, so as to prevent the thin rope 31 from getting stuck between the ball 28 and the limit frame 27 when the ball 28 rotates accordingly with the banknote;

[0064] Attached Fig.10 The middle dashed frame represents a dozen bills;

[0065] Attached Fig.11 Since the first circular ring 21 is fixed, the second circular ring 22 in contact with the first circular ring 21 rotates accordingly according to the principle that opposite charges attract and like charges repel.

[0066] Working principle:

[0067] Pull the folding plate 10 to place the whole banknotes between the folding plate 10 and the vertical rod 12, and then cancel the pulling of the folding plate 10, so that the whole banknotes are in contact with the vertical rod 12 under the action of the compression spring 11;

[0068] The motor 14 is started, so that the multiple rollers 1 begin to rotate. The rollers 1 rotate until they contact the whole dozen of banknotes. Under the action of magnetic attraction and repulsion between the first ring 21 and the second ring 22, the rotating rod 18 is driven to rotate, thereby driving the cam 19 to rotate accordingly, canceling the squeezing of the rubber sleeve 2, so that the space in the first area 3 is correspondingly increased, forming a negative pressure to adsorb the banknotes corresponding to the first through slot 5, and the adsorbed banknotes enter the U-shaped frame 23 and are detected by the detection sensor 24 on the U-shaped frame 23, which plays a counting role. After the counting is completed, the whole dozen of banknotes appears to be partially located on the folding plate 10 and the other part is located outside the slot body 8, and the middle position of the whole dozen of banknotes is bent by the vertical rod 12.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
