Description

Technical Field

[0001] The present invention relates to the technical field of banknote serial numbering, and in particular to a banknote serial numbering control method and a serial numbering machine for small banknotes. Background Art

[0002] The bill serial numbering process is to achieve the continuous number arrangement of every thousand bills. At present, after the quality inspection of ordinary bills, the defective bills will be removed. In the manufacturing process of general bills, it is only necessary to ensure the accuracy of the numbers of the bills, and there is no need to reprint and insert the defective bills. However, when producing some special bill products, such as commemorative bills, the removed bills will be reprinted according to the original prefix number, and it is required to be filled back to the original number position to ensure the continuity of the number of the whole thousand bills (generally arranged in order from small to large), that is, it is necessary to insert the supplementary bills (the original number bills that are invalidated and reprinted) back into the regular bills (the good bills after the defective bills are removed). At present, this work is basically completed manually, with low production efficiency and the situation that the bills are filled in the wrong position. The above problem is particularly serious when the commemorative bills have a high invalidation rate.

[0003] In the prior art, there is a technical solution that pre-stores the supplementary ticket number and uses paper counting to make up the supplementary ticket. That is, the paper counting machine stops at the position where the supplementary ticket information has been pre-stored, and a space for supplementary ticket is formed at the position where supplementary ticket needs to be made up, so as to realize the function of sequential number reinsertion. The above sequential number control method requires pre-storing supplementary ticket information. When the number of supplementary tickets is large, the efficiency of sequential number reinsertion is significantly reduced (the reinsertion action is slower); and the insertion position of the supplementary ticket is determined by counting the paper counting machine. The number on each banknote is not monitored during the sequential number reinsertion process, so there may be a problem of deviation in the insertion position of the supplementary ticket. Summary of the invention

[0004] The purpose of the present invention is to provide a banknote serial number control method and a serial number machine to solve the problems of low production efficiency and low accuracy in the current serial numbering process of small banknotes.

[0005] The above-mentioned implementation objectives of the present invention are mainly achieved by the following technical solutions:

[0006] In one aspect, the present invention provides a method for controlling the serial number of banknotes, comprising:

[0007] The original bills and supplementary bills that need serial numbers are placed on the first paper feeding mechanism and the second paper feeding mechanism that can feed the bills one by one to the paper receiving bin;

[0008] The logical number data is set to decrease or increase one by one based on the packaging sequence of the banknotes, and the logical number data is decreased or increased by one each time a banknote enters the paper receiving bin;

[0009] Identify the original note number information of the banknote currently conveyed by the first paper feeding mechanism and the supplementary note number information of the banknote currently conveyed by the second paper feeding mechanism;

[0010] The identified original ticket number information and the supplementary ticket number information are respectively compared with the logical number data, and the banknotes with the same logical number data are sent to the paper collection bin until all the banknotes are serially numbered.

[0011] In a preferred embodiment of the present invention, when the original ticket number information is different from the logical number data, the first paper feeding mechanism is paused and the identified number information of the first paper feeding mechanism is entered into the cache position; or, when the supplementary ticket number information is different from the logical number data, the second paper feeding mechanism is paused and the identified number information of the second paper feeding mechanism is entered into the cache position.

[0012] In a preferred embodiment of the present invention, when the main ticket number information is different from the logical number data, the supplementary ticket number information located in the cache position is compared with the logical number data. If the supplementary ticket number information located in the cache position is the same as the logical number data, the second paper feeding mechanism is activated. If the supplementary ticket number information located in the cache position is different from the logical number data, an alarm is triggered; or, when the supplementary ticket number information is different from the logical number data, the main ticket number information located in the cache position is compared with the logical number data. If the main ticket number information located in the cache position is the same as the logical number data, the first paper feeding mechanism is activated. If the main ticket number information located in the cache position is different from the logical number data, an alarm is triggered.

[0017] The identified first number information and the second number information are compared, and the first-time supplementary ticket and the second-time supplementary ticket are respectively sent into the paper receiving bin based on the order of number size until the supplementary tickets are stacked.

[0018] In a preferred embodiment of the present invention, before comparing the first number information and the second number information, the first number information currently recognized on the first paper feeding mechanism is compared with the previous first number information. If they do not conform to the current size arrangement order, an alarm is triggered; the second number information currently recognized on the second paper feeding mechanism is compared with the previous second number information. If they do not conform to the current size arrangement order, an alarm is triggered.

[0019] In a preferred embodiment of the present invention, the first-time supplementary ticket and the second-time supplementary ticket are respectively sent into the paper receiving bin based on the order of the number, including:

[0020] If the numbers are sorted from small to large (large logical numbers are sent first), then:

[0021] If the first number information is greater than the second number information, the first supplementary ticket is sent to the paper receiving bin, and the first number information and the second number information of the next ticket are compared again, until the first number information is less than the second number information, and the second supplementary ticket is sent to the paper receiving bin;

[0022] If the numbers are sorted from large to small (small logical numbers are transmitted first), then:

[0023] If the first number information is greater than the second number information, the second supplementary ticket is sent to the paper collection bin, and the first number information and the next second number information are compared again until the first number information is less than the second number information, and the first supplementary ticket is sent to the paper collection bin.

[0051] Implementation method 1:

[0052] like Figure 1 As shown, the present invention provides a method for controlling the serial number of banknotes, which comprises the following steps:

[0053] Step S1: placing the original bills and supplementary bills that need to be serially numbered on the first paper feeding mechanism and the second paper feeding mechanism that can feed the bills one by one to the paper receiving bin;

[0054] Step S2: setting the logical number data in descending or ascending order based on the packaging sequence of the banknotes, and the logical number data is decreased or increased by one each time a banknote enters the paper receiving bin;

[0055] Step S3: Identify the original note number information of the banknote currently being transported by the first paper feeding mechanism and the supplementary note number information of the banknote currently being transported by the second paper feeding mechanism;

[0056] Step S4: The identified original bill number information and supplementary bill number information are compared with the logical number data respectively, and the bills with the same logical number data are sent to the paper receiving bin until all the bills are numbered.

[0057] The banknote serial number control method of the present invention detects each banknote in the serial numbering process on the basis of realizing automatic banknote serial numbering, so as to ensure the continuity of the numbers on the banknotes in the serial numbering process.

[0058] Specifically, Figure 1 As shown, it shows the logical flow chart of the banknote sequence control method described in the present invention.

[0059] Firstly, the first paper feeding mechanism and the second paper feeding mechanism of the present invention are turned on, and the whole sequential process starts to run.

[0060] In step S1, the original bill after the invalid bill is removed is placed on the first paper feeding mechanism, and the replacement bill reprinted according to the invalid bill information is placed on the second paper feeding mechanism. The placement positions of the original bill and the replacement bill can be interchanged. In order to facilitate the description of the sequence number control method of the present invention, the following description is based on the example that the original bill is placed on the first paper feeding mechanism and the replacement bill is placed on the second paper feeding mechanism.

[0061] In step S2, a logic number data which decreases or increases one by one is set in the control system, and the logic number data increases or decreases in real time according to the number of banknotes transported into the paper receiving bin through the second paper feeding mechanism and the first paper feeding mechanism. In order to facilitate the description of the sequential number control method described in the present invention, the following description is made by taking the logic number data decreasing one by one as an example, that is, for each banknote entering the paper receiving bin, the logic number data decreases by one; accordingly, the number information of the original banknotes put into the first paper receiving bin increases gradually from top to bottom, and the number information of the supplementary banknotes put into the second paper receiving bin increases gradually from top to bottom.

[0062] The logical number data in the control system corresponds to the number information on the original bills and supplementary bills that need to be processed in sequence. For example, if one thousand bills with number information from 0001 to 1000 need to be processed in sequence, the logical number data in the control system is set to decrease from 1000 to 0001 one by one. The default initial logical number data is x000, which decreases to 999 until 001, and starts at the next (x-1)000. The initial number can also be entered as any number.

[0063] In step S3, a conventional image recognition mechanism is used to respectively identify the original ticket number information of the banknote currently being conveyed by the first paper feeding mechanism and the supplementary ticket number information of the banknote currently being conveyed by the second paper feeding mechanism, and the identified original ticket number information and supplementary ticket number information are transmitted to the control system.

[0064] In step S4, the recognized original ticket number information is compared with the current logical number data in the control system. If the two are the same, the original ticket currently transported by the first paper feeding mechanism is transported into the paper receiving bin. If they are different, the transport of the first paper feeding mechanism is suspended and the number information recognized by the first paper feeding mechanism is entered into the cache. At the same time, the recognized supplementary ticket number information is compared with the current logical number data in the control system. If the two are the same, the supplementary ticket currently transported by the second paper feeding mechanism is transported into the paper receiving bin. If they are different, the transport of the second paper feeding mechanism is suspended and the number information recognized by the second paper feeding mechanism is entered into the cache.

[0065] During the normal numbering process, only one of the number information of the original ticket currently transported by the first paper feed mechanism and the number information of the supplementary ticket currently transported by the second paper feed mechanism will be the same as the current logical number data in the control system. Therefore, during the normal numbering process, one of the first paper feed mechanism and the second paper feed mechanism operates normally, and the other is in a paused state, and the states of the two are constantly switched during the numbering process.

[0066] Further, such as Figure 1 As shown, when the original ticket number information on the first paper feeding mechanism is different from the logical number data, the first paper feeding mechanism is paused, and the supplementary ticket number information located at the cache position on the second paper feeding mechanism is compared with the logical number data. If the supplementary ticket number information located at the cache position is the same as the logical number data, the second paper feeding mechanism is started to transport the supplementary ticket to the paper receiving bin. If the supplementary ticket number information located at the cache position is different from the logical number data, an alarm is triggered (at this time, both the original ticket number information and the supplementary ticket number information are different from the logical number data, and there is a position error of some bills in the original ticket or the supplementary ticket, which needs to be handled manually);

[0067] Or, if Figure 1 As shown, when the supplementary ticket number information on the second paper feeding mechanism is different from the logical number data, the second paper feeding mechanism is paused and the original ticket number information located in the cache position on the first paper feeding mechanism is compared with the logical number data. If the original ticket number information located in the cache position is the same as the logical number data, the first paper feeding mechanism is turned on to transport the original ticket to the paper receiving bin. If the original ticket number information located in the cache position is different from the logical number data, an alarm is triggered (at this time, the original ticket number information and the supplementary ticket number information are both different from the logical number data, and there are errors in the position of some banknotes in the original ticket or the supplementary ticket, which require manual processing).

[0068] The serial number control method described in the present invention is preferably suitable for the serial number processing process with a large number of invalid bills. If there are only a few invalid bills in the printed banknotes, the serial number processing process with a small number of invalid bills using the serial number processing method described in the present invention is actually less efficient than manual serial numbering.

[0069] According to one embodiment of the present invention, in the actual printing process of banknotes, especially in the process of printing replacement bills based on invalid bills in the original bills, the printed replacement bills may still contain some invalid bills, so it is necessary to reprint the invalid bills in the first replacement bill, and then generate a second replacement bill (also generate three, four or even more replacement bills, generally in small quantities, and can be manually operated). Before the serial number processing is performed, the second replacement bill needs to be inserted into the first replacement bill in the order of the size of the number;

[0070] like Figure 2As shown, before the supplementary bill is put into the second paper feeding mechanism, the bill sequence control method of the present invention further includes the following steps:

[0071] Step S01: placing the first-time payment ticket and the second-time payment ticket that need to be stacked in order of number size on the first paper feeding mechanism and the second paper feeding mechanism respectively;

[0072] Step S02: Identify the first number information of the banknote currently being transported by the first paper feeding mechanism and the second number information of the banknote currently being transported by the second paper feeding mechanism;

[0073] Step S03: Compare the identified first number information and second number information, and send the first-time supplementary ticket and the second-time supplementary ticket into the paper receiving bin respectively based on the order of number size until the supplementary tickets are stacked.

[0074] The banknote sequence control method described in the present invention can replenish the secondary replenishment bill into the primary replenishment bill, and then replenish the newly formed primary replenishment bill into the original bill.

[0075] Specifically, Figure 2 As shown, in step S01, the first-time supplementary bill after the invalid bill is removed is placed on the first paper feeding mechanism, and the second-time supplementary bill reprinted according to the invalid bill information is placed on the second paper feeding mechanism. The placement positions of the first-time supplementary bill and the second-time supplementary bill can be interchanged. In order to facilitate the description of the sequence number control method of the present invention, the following description is based on the first-time supplementary bill being placed on the first paper feeding mechanism and the second-time supplementary bill being placed on the second paper feeding mechanism.

[0076] In step S02, a conventional image recognition mechanism is used to respectively identify the first number information of the single-issue ticket currently being transported by the first paper feeding mechanism and the second number information of the double-issue ticket currently being transported by the second paper feeding mechanism, and the identified first number information and second number information are transmitted to the control system.

[0077] In step S03, the identified first number information and the second number information are compared, and the first and second replacement tickets are sent to the paper receiving bin in the order of the number until the replacement tickets are stacked.

[0078] Further, such as Figure 2 As shown, in this embodiment, the first-time supplementary bills and the second-time supplementary bills are sorted in order of number size from small to large, that is, the bills with larger numbers are first transmitted to the paper receiving bin, then:

[0079] When the first number information on the first conveying mechanism is greater than the second number information on the second conveying mechanism, the first supplementary ticket is sent to the paper receiving bin, and the second paper feeding mechanism is paused at the same time, and the identified second number enters the cache position. Since the first conveying mechanism continues to operate, the first number information is constantly updated at this time, and is constantly compared with the previous first number information during the updating process. If it is greater than the previous first number information, an alarm is triggered, and the updated first number information is compared with the second number information in the cache position until the updated first number information is less than the second number information. At this time, the first paper feeding mechanism is paused, and the identified first number information enters the cache position, and the second paper feeding mechanism is turned on at the same time to send the second supplementary ticket to the paper receiving bin;

[0080] Alternatively, when the second number information on the second conveying mechanism is greater than the first number information on the first conveying mechanism, the second supplementary ticket will be sent to the paper receiving bin, and the first paper feeding mechanism will be paused at the same time, and the identified first number information will enter the cache position. Since the second conveying mechanism continues to run, the second number information is constantly updated at this time, and is constantly compared with the previous second number information during the updating process. If it is greater than the previous second number information, an alarm will be triggered, and the updated second number information will be compared with the first number information located in the cache position until the updated second number information is less than the first number information. At this time, the second paper feeding mechanism will be paused, and the identified second number information will enter the cache position, and the first paper feeding mechanism will be turned on to send the first supplementary ticket into the paper receiving bin.

[0081] During the normal operation of a second ticket replenishment to replenish a first ticket replenishment, there is a size relationship between the first number information of the first ticket replenishment currently transported by the first paper feeding mechanism and the second number information of the second ticket replenishment currently transported by the second paper feeding mechanism. Therefore, during the normal replenishment process, only one of the first paper feeding mechanism and the second paper feeding mechanism operates normally, and the other is in a paused state, and the states of the two are constantly switched during the replenishment process.

[0082] According to one embodiment of the present invention, Figure 2 As shown, during the operation of the second ticket replenishment to make up for the first ticket replenishment, it is determined whether the front and rear numbers on the same side of the first paper feeding mechanism and the second paper feeding mechanism meet the set judgment logic from large to small or from small to large. If not, the system stops and triggers an alarm.

[0083] Implementation method 2:

[0084] like Figure 3As shown, the present invention also provides a serial numbering machine, which can implement the banknote serial numbering control method as described in Implementation Example 1, and comprises: a first banknote input mechanism 10, having a first paper feeding unit 11 for conveying banknotes and a first identification unit 12 for identifying banknote number information; a second banknote input mechanism 20, having a second paper feeding unit 21 for conveying banknotes and a second identification unit 22 for identifying banknote number information; and a paper receiving bin 30, located between the outlet of the first paper feeding unit 11 and the outlet of the second paper feeding unit 21.

[0085] The serial numbering machine described in the present invention can realize the serial numbering process of banknotes and notes, especially when there are many invalid banknotes, the use of the serial numbering machine described in the present invention can greatly improve the efficiency of the serial numbering of banknotes and notes; at the same time, the serial numbering machine described in the present invention detects the number on each banknote and note during the serial numbering process to ensure the continuity of the banknote and note numbers during the serial numbering process.

[0086] Specifically, Figure 3 As shown, the first banknote-introducing mechanism 10 and the second banknote-introducing mechanism 20 are symmetrically arranged, respectively located on both sides of the paper receiving bin 30. The first banknote-introducing mechanism 10 can deliver the banknotes thereon into the paper receiving bin 30 one by one, and the second banknote-introducing mechanism 20 can also deliver the banknotes thereon into the paper receiving bin 30 one by one.

[0087] Further, such as Figure 3 As shown, the first paper feeding unit 11 of the first cash-in mechanism 10 has a first main driving belt 111 and a first conveying belt 112 adjacently arranged along the same conveying direction, and the output end of the first conveying belt 112 is opposite to the paper receiving bin 30; the second paper feeding unit 21 of the second cash-in mechanism 20 has a second main driving belt 211 and a second conveying belt 212 adjacently arranged along the same conveying direction, and the output end of the second conveying belt 212 is opposite to the paper receiving bin 30.

[0088] On the first paper feeding unit 11, the banknotes placed on the first main driving belt 111 enter the first conveying belt 112 driven by the first main driving belt 111. When the banknotes enter the first conveying belt 112, the first identification unit 12 can identify the number information of the banknotes being transported on the first conveying belt 112; on the second paper feeding unit 21, the banknotes placed on the second main driving belt 211 enter the second conveying belt 212 driven by the second main driving belt 211. When the banknotes enter the second conveying belt 212, the second identification unit 22 can identify the number information of the banknotes being transported on the second conveying belt 212.

[0089] According to one embodiment of the present invention, the running speed of the first conveyor belt 112 is greater than that of the first main drive belt 111, thereby increasing the relative distance between the banknotes on the first conveyor belt 112, ensuring that there is only one banknote in the cache position, and when the first paper feeding unit 11 stops, it can also better separate the banknotes in the cache position and the banknotes entering the paper collection bin; similarly, the running speed of the second conveyor belt 212 is greater than that of the second main drive belt 211.

[0090] According to one embodiment of the present invention, the first paper feeding unit 11 and the second paper feeding unit 21 are respectively provided with a first bill compartment 40 and a second bill compartment 50 , wherein the first bill compartment 40 is provided with a genuine bill 41 , and the second bill compartment 50 is provided with a replacement bill 51 .

[0091] Specifically, Figure 3 As shown, the first banknote compartment 40 is arranged above the first main driving belt 111, and its length direction is perpendicular to the transmission direction of the first main driving belt 111; the second banknote compartment 50 is arranged above the second main driving belt 211, and its length direction is perpendicular to the transmission direction of the second main driving belt 211.

[0092] The first bill compartment 40 is provided with a genuine bill 41, and the second bill compartment 50 is provided with a supplementary bill 51; or, the first bill compartment 40 is provided with a supplementary bill 51, and the second bill compartment 50 is provided with a genuine bill 41. The first bill entry mechanism 10 and the second bill entry mechanism 20 are symmetrically arranged, so that the placement positions of the genuine bill 41 and the supplementary bill 51 can be interchanged.

[0093] The first bill compartment 40 is provided with a bill outlet (not shown) at one end close to the first main driving belt 111. The bills at the bottom layer in the first bill compartment 40 are in contact with the first main driving belt 111. Under the action of friction, the original bills 41 or the supplementary bills 51 placed in the first bill compartment 40 can be output from the bill outlet one by one under the drive of the first main driving belt 111. The second bill compartment 50 is provided with a bill outlet (not shown) at one end close to the second main driving belt 211. The bills at the bottom layer in the second bill compartment 50 are in contact with the second main driving belt 211. Under the action of friction, the original bills 41 or the supplementary bills 51 placed in the second bill compartment 50 can be output from the bill outlet one by one under the drive of the second main driving belt 211.

[0094] According to one embodiment of the present invention, Figure 3As shown, a first reverse wheel 13 is provided at the exit of the first bill compartment 40, and a second reverse wheel 23 is provided at the exit of the second bill compartment 50. The rotation direction of the first reverse wheel 13 is the same as the rotation direction of the first main driving belt 111, so it is toward the direction of the bill, and the movement direction of the first reverse wheel 13 is opposite to the conveying direction of the bill. The rotation direction of the second reverse wheel 23 is the same as the rotation direction of the second main driving belt 211, so it is toward the direction of the bill, and the movement direction of the second reverse wheel 23 is opposite to the conveying direction of the bill.
