Description

Technical Field

[0001] The present invention relates to the technical field of high-speed toll collection equipment, and particularly to an invoice auxiliary conveying mechanism for an invoice printer. Background Art

[0002] At present, there are mainly various ways to collect vehicle tolls at highway toll stations across the country. Among them, ETC (Electronic Toll Collection) is an advanced toll collection method. Through wireless communication and information exchange between in-vehicle electronic tags and microwave antennas on toll station lanes, it realizes non-stop fast passing and automatic deduction of fees, greatly improving the toll collection efficiency and reducing the waiting time of vehicles in line, and is favored by the majority of vehicle owners. The manual toll collection method is a traditional toll collection mode, where toll collectors manually operate toll collection equipment to calculate and collect fees for passing vehicles. Although this method can handle special situations to a certain extent, the toll collection speed is relatively slow and human errors are prone to occur. In addition, self-service payment machines are also a toll collection method gradually promoted in recent years. It allows vehicle owners to complete the payment process by themselves, which is convenient for vehicle owners and reduces the pressure on manual toll collection.

[0003] In addition to the above different toll collection methods, during the toll collection process at highway exits, the ways of issuing invoices also show diverse characteristics according to the specific management requirements and actual situations in different regions. Specifically, it is mainly divided into several forms such as printing paper invoices, printing paper invoice vouchers, and electronic invoices.

[0004] In terms of printing paper invoices, it is further divided into two different types. One is manual printing. This method usually does not have a secondary conveying function, that is, after printing, it is necessary for the operator to take out the invoice from the printer and hand it to the vehicle owner. At the same time, this manual printing method generally does not have a waste invoice recycling function, and the discarded invoices are often randomly discarded or piled up beside, lacking an effective management and recycling mechanism, which not only easily causes waste of resources but also may cause certain pollution to the environment. The other is to realize automatic printing of invoices through self-service payment machines. This method usually has a secondary conveying function and can automatically convey the invoice to a designated position after printing, which is convenient for vehicle owners to pick up. The invoice printing system of some self-service payment machines also has a waste invoice recycling function. When printing errors or other abnormal situations occur, it can automatically recycle the discarded invoices and perform corresponding processing, which improves the utilization rate of resources and the cleanliness of the environment to a certain extent.

[0005] However, in the actual use process, there are also some problems with the invoice automatic printing system of this self-service payment machine. Among them, the more prominent one is the out-of-sync situation between the secondary conveying function and the invoice printer. Since the invoice printer and the secondary conveying device are controlled by different control systems respectively, the coordination and cooperation between the two are not precise enough, resulting in frequent paper jams during the invoice printing and conveying process. Once a paper jam occurs, it will not only affect the normal charging process, cause the vehicle queuing waiting time to extend, reduce the charging efficiency, but also bring inconvenience to the vehicle owners, and even may lead to some unnecessary disputes. In addition, the paper jam problem may also cause invoice damage or loss, increasing the management cost and work difficulty. Therefore, how to solve the paper jam problem caused by the out-of-sync between the secondary conveying and the printer in the self-service payment machine invoice printing system and improve the efficiency and quality of invoice printing has become an urgent technical problem in the current highway toll collection field.

[0060] The following will be combined with Figures 1 to 4Elaborate on the principle and implementation method of the invoice auxiliary conveying mechanism of an invoice printer in this embodiment, so that those skilled in the art can understand the invoice auxiliary conveying mechanism of the invoice printer in this embodiment without creative labor.

[0061] An embodiment of the present application provides an invoice auxiliary conveying mechanism for an invoice printer. As Figure 1 shown, the invoice auxiliary conveying mechanism 100 is installed at the front end of the invoice printer 200, and performs secondary transmission on the invoice output after the invoice printer 200 finishes printing, avoiding the problem that the driver directly and forcibly pulls the invoice during the printing process of the invoice printer 200.

[0062] Figure 2 It shows a schematic diagram of the overall structure of the invoice auxiliary conveying mechanism 100 of the invoice printer 200 in an embodiment of the present application. As Figure 2 shown, the invoice auxiliary conveying mechanism 100 includes a support frame 110, a conveying belt 120, a belt driving assembly 130, an auxiliary pressing wheel assembly 140, a push rod assembly 150, a push rod driving assembly 160, and an invoice outlet channel 170.

[0063] Among them: The belt driving assembly 130 controls the operation of the conveying belt 120. The conveying belt 120 is arranged in the support frame 110 and is docked with the output port of the invoice printer 200, and is used to transmit the invoice output by the invoice printer 200 to the invoice outlet channel 170; the auxiliary pressing wheel assembly 140 is installed on the belt; the push rod assembly 150 is connected to the auxiliary pressing wheel assembly 140, and under the drive of the push rod driving assembly 160, pushes the auxiliary pressing wheel assembly 140 to move upward away from the conveying belt 120, or downward close to the conveying belt 120, so as to control the transmission of the invoice on the conveying belt 120.

[0064] In this embodiment, when the invoice printer 200 is working, the push rod driving assembly 160 drives the push rod assembly 150 to move, thereby pushing the auxiliary pressing wheel assembly 140 upward away from the conveying belt 120, so as to eliminate the blockage of the invoice during the transmission process of the invoice to the ticket auxiliary conveying mechanism, and the invoice can be freely output to the ticket auxiliary conveying mechanism. Thus, the problem of the speed mismatch between the invoice auxiliary conveying mechanism 100 and the invoice printer 200 is avoided, the interference of external reasons to the invoice printer 200 is eliminated, and the invoice printer 200 is in an optimal state. When the invoice printer 200 finishes, the printed invoice is cut off from the subsequent blank invoice, and the printed invoice is output onto the conveying belt 120 of the invoice auxiliary conveying mechanism 100. At this time, the push rod driving assembly 160 drives the push rod assembly 150 to move in the opposite direction, thereby pushing the auxiliary pressing wheel assembly 140 downward to be close to the conveying belt 120 and pressing the invoice on the conveying belt 120, and the invoice is closely attached to the conveying belt 120, which is convenient for the conveying belt 120 to drive the invoice to be conveyed forward or backward.

[0065] The following will detail the support frame 110, the conveying belt 120, the belt driving assembly 130, the auxiliary pressing wheel assembly 140, the push rod assembly 150, the push rod driving assembly 160, and the invoice outlet channel 170 of the ticket auxiliary conveying mechanism in this embodiment.

[0066] In this embodiment, the support frame 110 is used to support the conveying belt 120, the belt driving assembly 130, the auxiliary pressing wheel assembly 140, the push rod assembly 150, the push rod driving assembly 160, and the invoice outlet channel 170, so that the two ends of the conveying belt 120 are respectively docked with the output port of the invoice printer 200 and the invoice outlet channel 170. The invoice output by the invoice printer 200 can directly enter the conveying belt 120, and the conveying belt 120 then conveys the invoice to the invoice outlet channel 170, so that the driver can obtain the invoice from the invoice outlet channel 170.

[0067] In a specific implementation manner of this embodiment, the support frame 110 includes first support side plates and second support side plates on the left and right sides, a support bottom plate connected between the bottom ends of the first support side plates and the second support side plates, and a cross beam connected between the top ends of the first support side plates and the second support side plates; the first support side plates, the second support side plates, the support bottom plate, and the cross beam form a containing space for containing the conveying belt 120, the belt driving assembly 130, the auxiliary pressing wheel assembly 140, the push rod assembly 150, and the push rod driving assembly 160.

[0068] Among them, the invoice export channel 170 is arranged at the front end of the support frame 110. In this embodiment, a waste invoice recycling box 180 is further included, which is arranged at the opposite end of the invoice export channel 170 and outside the transmission belt. The first support side plate and the second support side plate of the support frame 110 are fixed on the waste invoice recycling box 180, so that the support frame 110 maintains a certain height corresponding to the invoice output port of the invoice printer 200.

[0069] In a specific implementation manner of this embodiment, the push rod assembly 150 includes a first side arm 151, a second side arm 152, and a push rod support end 153; the first side arm 151 and the second side arm 152 are respectively fixedly connected to both ends of the auxiliary pressure wheel assembly 140, and the push rod support end 153 is arranged at the top of the first side arm 151 and the second side arm 152. When the pushing end moves, it drives the first side arm 151 and the second side arm 152 to move up or down.

[0070] Among them, the first side arm 151, the second side arm 152, and the push rod support end 153 form a fixed frame structure for fixing the auxiliary pressure wheel assembly 140. The auxiliary pressure wheel assembly 140 is located within the fixed frame structure formed by the first side arm 151, the second side arm 152, and the push rod support end 153.

[0071] Specifically, in this embodiment, the auxiliary pressure wheel assembly 140 includes multiple groups of auxiliary pressure wheels 141 arranged along the conveyor belt 120. Each group of pressure wheels includes a connecting shaft and at least one auxiliary pressure wheel 141 installed on the connecting shaft. Both ends of the connecting shaft are respectively fixed to the first side arm 151 and the second side arm 152. In this way, by moving the first side arm 151 and the second side arm 152 up or down, the auxiliary pressure wheel 141 can be driven to lift up or drop down.

[0072] In this embodiment, the purpose of driving the auxiliary pressure wheel 141 to lift up or drop down is achieved by controlling the push rod support end 153.

[0073] Specifically, in a specific implementation manner of this embodiment, as Figure 3 shown, the push rod drive assembly 160 includes a push rod drive motor 161, a push rod drive gear 162, a push rod rack 163, and a rotating shaft 164; the push rod drive motor 161 drives the push rod drive gear 162 to operate; the push rod drive gear 162 meshes with the push rod rack 163 to drive the push rod rack 163 to move; the rotating shaft 164 is connected to the push rod rack 163 and is driven by the push rod rack 163 to flip; the rotating shaft 164 is placed on the push rod support end 153 and pushes the push rod support end 153 to move when flipping.

[0074] By controlling the moving direction of the push rod rack 163 through the push rod driving motor 161, the flipping direction of the rotating shaft 164 can be controlled, so as to realize the control of the push rod support end 153 in different directions.

[0075] In this embodiment, when the rotating shaft 164 flips forward, it will apply pressure to the push rod support end 153. Since the bottom of the push rod support end 153 is suspended, the rotating shaft 164 pushes the push rod support end 153 to move forward, so that the first side arm 151 and the second side arm 152 are lifted upward, driving the auxiliary pressing wheel 141 to lift upward. When the rotating shaft 164 rotates back, the rotating shaft 164 presses the push rod support end 153 to move backward, so that the first side arm 151 and the second side arm 152 move downward, driving the auxiliary pressing wheel 141 to press the transmission belt downward.

[0076] To make the rotating shaft 164 facilitate the control of the push rod support end 153, in a specific implementation manner of this embodiment, as Figure 4 shown, the push rod support end 153 is bent upward relative to the first side arm 151 and the second side arm 152; the push rod support end 153 has a support surface; the support surface is attached to the outer surface of the rotating shaft 164.

[0077] In a specific implementation manner of this embodiment, as Figure 3 shown, the push rod driving motor 161 is arranged outside the support frame 110 in the vertical direction, the push rod driving gear 162 is arranged at the bottom end of the push rod driving motor 161, and the push rod rack 163 is engaged with the push rod driving gear 162 in the horizontal direction. The rotating shaft 164 is installed on the push rod support end 153 and is perpendicular to the push rod rack 163. By the forward and backward horizontal movement of the push rod rack 163, the up and down flipping of the rotating shaft 164 can be driven. Furthermore, the up and down movement of the auxiliary pressing wheel 141 is realized.

[0078] In this embodiment, when the invoice printer 200 is working, the push rod drive motor 161 drives the push rod drive gear 162 to run; the push rod drive gear 162 meshes with the push rod rack 163, driving the push rod rack 163 to move forward. The push rod rack 163 drives the rotating shaft 164 to turn downward, and the rotating shaft 164 pushes the push rod support end 153 to move forward, so that the first side arm 151 and the second side arm 152 are lifted upward, driving the auxiliary pressure wheel 141 to lift upward and leave the surface of the conveyor belt 120, eliminating the blockage of the invoice during the transmission of the invoice to the conveyor belt 120 of the invoice auxiliary conveying mechanism 100. The invoice can be freely output to the invoice auxiliary conveying mechanism, thus avoiding the problem of speed mismatch between the invoice auxiliary conveying mechanism 100 and the invoice printer 200, eliminating the interference of external reasons on the invoice printer 200, and making the invoice printer 200 in an optimal state.

[0079] When the invoice printer 200 finishes, the printed invoice is cut off from the subsequent blank invoice, and the printed invoice is output onto the conveyor belt 120 of the invoice auxiliary conveying mechanism 100. At this time, the push rod drive motor 161 drives the push rod drive gear 162 to rotate in the reverse direction. The push rod drive gear 162 meshes with the push rod rack 163, driving the push rod rack 163 to move backward. The push rod rack 163 drives the rotating shaft 164 to turn in the opposite direction, and the rotating shaft 164 pushes the push rod support end 153 to move backward, so that the first side arm 151 and the second side arm 152 move downward, thereby driving the auxiliary pressure wheel 141 to move downward and close to the conveyor belt 120, and pressing the invoice on the conveyor belt 120. The invoice is closely attached to the conveyor belt 120, facilitating the conveyor belt 120 to drive the invoice to be conveyed forward or backward.

[0080] As Figure 3 and Figure 4 shown, in a specific implementation manner of this embodiment, the belt drive assembly 130 includes a power wheel gear 131, a power wheel motor 133 that drives the power wheel gear 131, a driving wheel gear 132 connected to the power wheel gear 131, and a driven wheel group 134 connected to the driving wheel gear 132; wherein the conveyor belt 120 is installed on the driven wheel group 134 and is driven to run through the driven wheel group 134. Among them, the driven wheel group 134 includes at least two driven wheels placed in parallel.

[0081] Among them, the power wheel motor 133 is placed below the transmission belt, and the power wheel gear 131 and the driving wheel gear 132 are placed on the outer surface of the support frame 110.

[0082] Specifically, the driving wheel motor 133 drives the driving wheel gear 131, the driving wheel gear 131 drives the driving wheel gear 132, and the driving wheel gear 132 drives the driven wheel group 134 provided with the conveyor belt 120 to operate. The conveyor belt 120 surrounds the driven wheel group 134 and rotates cyclically along the driven wheel group 134.

[0083] Among them, in this embodiment, a belt or a chain drive can be adopted between the driving wheel gear 131 and the driving wheel gear 132.

[0084] In addition, in a specific implementation manner of this embodiment, the belt drive assembly 130 further includes a stop portion that is cooperatively connected to the driven wheel group 134 and limits the operation of the driven wheel group 134. Among them, as Figures 2 to 4 shown, for example, if there are two driven wheels in the driven wheel group 134, the stop portion includes two: the stop portion 135 and the stop portion 136, and one stop portion is correspondingly provided for each driven wheel.

[0085] In this embodiment, the driven wheel group 134 includes at least two driven wheels placed in parallel. When the driven wheels rotate forward, they drive the transmission belt to run forward and convey the invoice to the invoice outlet channel 170. When the driven wheels rotate backward, they drive the transmission belt to run backward and convey the invoice into the waste invoice recycling bin 180.

[0086] To enable those skilled in the art to further understand the principle and implementation manner of the invoice auxiliary conveying mechanism 100 of this embodiment, the following describes the usage process of the invoice auxiliary conveying mechanism 100 of this embodiment.

[0087] Multiple rolls of unprinted invoices are placed in the invoice box 300. An operator loads one roll of unprinted invoice into the invoice printer 200. When the invoice printer 200 is printing, the invoice auxiliary pressing wheel 141 is in the up-flipped and opened state. When the invoice printer 200 prints each line of information, the invoice conveying is intermittent and is continuously conveyed onto the conveyor belt. After all invoice information is printed, the invoice is completely sent out of the invoice printer 200 and is automatically cut.

[0088] When the invoice auxiliary conveying mechanism 100 is working, the driven wheel drives the transmission belt to run forward when rotating forward, and the push rod drive motor 161 drives the push rod drive gear 162 to run; the push rod drive gear 162 meshes with the push rod rack 163, driving the push rod rack 163 to move forward. The push rod rack 163 drives the rotating shaft 164 to turn downward by an angle, and the rotating shaft 164 pushes the push rod support end 153 to move forward a certain distance, so that the first side arm 151 and the second side arm 152 are lifted upward, driving the auxiliary pressure wheel 141 to lift upward and leave the surface of the conveying belt 120, making the auxiliary pressure wheel 141 in the upward-turning and open state to actively avoid the invoices on the conveying belt 120, eliminating the blockage of the invoices during the transmission of the invoices to the conveying belt 120 of the invoice auxiliary conveying mechanism 100. The invoices can be freely output to the invoice auxiliary conveying mechanism, thus avoiding the problem of the speed mismatch between the invoice auxiliary conveying mechanism 100 and the invoice printer 200, eliminating the interference of external reasons to the invoice printer 200, and making the invoice printer 200 in the optimal state.

[0089] When the printer finishes printing and cuts off, the auxiliary pressure wheel 141 is driven by the reverse rotation of the push rod drive gear 162 to mesh with the push rod rack 163 and move backward, so that the auxiliary pressure wheel 141 turns downward to press the invoice tightly, and the invoice is closely attached to the conveying belt 120, facilitating the conveying belt 120 to drive the invoice to convey forward and backward.

[0090] When the driver needs an invoice, the invoice will be sent out through the invoice outlet channel 170 by the conveying belt 120, and this process is completed after the subsequent invoice-taking action is completed. When the invoice is printed and the driver does not need the invoice, control the conveying belt 120 to convey a certain distance in the direction of the invoice outlet channel 170 first to make the invoice completely exceed the position of the waste invoice recycling port, and then control the conveying belt 120 to convey in the reverse direction to convey the waste invoice into the waste invoice recycling channel and enter the waste invoice box through the waste invoice recycling channel to complete the waste invoice recycling process.

[0091] The overall structure of the invoice auxiliary conveying mechanism 100 in this embodiment is simple and compact, which can comprehensively solve the problem of speed mismatch between the invoice printer 200 of the self-service payment machine and the adaptive conveying and recycling device, as well as various invoice jamming and other fault problems caused by the matching problem. Thereby reducing the selection restrictions, replacement restrictions, equipment costs, as well as the debugging and post-maintenance costs and the labor intensity of the toll station special personnel, and at the same time improving the intelligent technology of the intelligent toll station.

[0092] In summary, in this embodiment, the push rod driving assembly 160 drives the push rod assembly 150 to move, pushing the auxiliary pressure wheel assembly 140 to move upward away from the conveyor belt 120 to control the transmission of invoices on the conveyor belt 120, enabling the auxiliary pressure wheel 141 to actively avoid the invoices entering the transmission belt, eliminating the blockage of the invoices during the printing process, and allowing the invoices to be freely output during printing, thereby avoiding the paper jam problem caused by the asynchronous operation of invoice transmission and the invoice printer 200, eliminating the interference of external factors on the invoice printer 200, and enabling the invoice printer 200 to be in an optimal state. When the invoice moves towards the invoice exit channel 170, the auxiliary pressure wheel 141 flips downward to press the invoice tightly, and the invoice adheres closely to the conveyor belt 120, facilitating the conveyor belt 120 to drive the invoice to be conveyed back and forth; the overall mechanism of this application is simple and compact, which can comprehensively solve the problem of speed mismatch between the invoice printer 200 of the self-service payment machine and the transmission belt, as well as various invoice paper jam and other fault problems caused by the matching problem, thereby reducing the selection restrictions, replacement restrictions, equipment costs, as well as the debugging and later maintenance costs and the labor intensity of toll station special service personnel. At the same time, it also improves the intelligence level of the intelligent toll station. Therefore, this application overcomes various shortcomings of the existing invoice printers and has high innovation.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in this application should still be covered by the claims of this application.
