DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] refer to Figure 1The embodiment of the present invention provides a ticket terminal service device, which includes a ticket input conveying channel 2. A transceiver mechanism 1 is provided at the first end of the ticket input conveying channel 2. A ticket input port 101 and a ticket output port 102 are configured on the transceiver mechanism 1. A cache conveying channel 3 is provided at the second end of the ticket input conveying channel 2. The cache conveying channel 3 is used to store at least one ticket conveyed from the ticket input conveying channel 2 and convey the ticket according to the user's confirmation information. The first end of the cache conveying channel 3 is close to the ticket input conveying channel 2, and the second end of the cache conveying channel 3 is connected to the first end of the printing conveying channel 4. The printing conveying channel 4 is provided with a printing mechanism 402. The printing mechanism 402 is used to print a corresponding mark on the ticket.

[0028] The transceiver mechanism 1 is used for absorbing and discharging bills. The size of the ticket inlet 101 can be limited so that only a single ticket is allowed to be inserted in one operation. Each conveying channel is a channel that can realize the transportation and movement of bills. The bill to be operated enters the ticket conveying channel 2 through the transceiver mechanism 1, and the bill in the ticket conveying channel 2 can be conveyed to the cache conveying channel 3. Multiple bills can be inserted continuously through the transceiver mechanism 1. When multiple bills are stored in the cache conveying channel 3 at the same time, confirmation information can be sent to the user, and the user confirms the business operation of multiple bills (such as refund). When the user's confirmation information at this time is to confirm the business operation, the cache conveying channel 3 can convey the bill to the printing conveying channel 4, and the printing mechanism 402 prints the corresponding operation mark (such as the word "return") and serial number and other information on the bill, so that maintenance personnel can distinguish them.

[0029] The present embodiment provides a ticket terminal service device that can automatically implement business operations of tickets (such as ticket refund operations). The entire ticket refund process does not require the operation of ticket agents, which reduces the labor intensity of ticket agents and is conducive to improving efficiency. At the same time, a cache conveying channel 3 is provided, and the user can operate multiple tickets at a time, which greatly simplifies the operation process, saves the user's operation time, and further improves efficiency.

[0030] Furthermore, the first end of the buffer conveying channel 3 is set at a lower height than the second end of the ticket feeding conveying channel 2, which is convenient for storing multiple bills. The second end of the ticket feeding conveying channel 2 can be connected to a downwardly inclined guide plate, so that the bills on the ticket feeding conveying channel 2 can be smoothly conveyed to the buffer conveying channel 3.

[0031] On the basis of the above embodiment, further, a ticket rubbing mechanism 6 is provided at the second end of the buffer conveying channel 3 , and the ticket rubbing mechanism 6 is used to convey the single tickets to the printing conveying channel 4 in sequence.

[0032] Specifically, refer to Figure 1 and Figure 2The ticket rubbing mechanism 6 includes a ticket rubbing rubber roller 601 and a damping member 602 which are arranged at the second end of the cache conveying channel 3 relative to each other in upper and lower directions. The ticket rubbing rubber roller 601 is rotatably arranged, and the damping member 602 is fixedly arranged. A ticket rubbing channel connecting the cache conveying channel 3 and the printing conveying channel 4 is formed between the ticket rubbing rubber roller 601 and the damping member 602.

[0033] The ticket-rubbing mechanism 6, i.e., the ticket separation and printing mechanism 402, is located behind the buffer conveying channel 3 and is used to separate multiple tickets in the buffer conveying channel 3 into single tickets and discharge them in sequence. The ticket-rubbing mechanism 6 includes a driving mechanism, a ticket-rubbing rubber roller 601, and a damping member 602. When the ticket separation starts, the driving mechanism drives the ticket-rubbing rubber roller 601 to rotate, which is used to provide power for the ticket conveying and moving. The ticket-rubbing rubber roller 601 takes away the top ticket of the buffer conveying channel 3, and the damping member 602 prevents the next ticket from being discharged at the same time. The principle is to separate the tickets that fall together one by one by utilizing the friction between the damping member 602 and the ticket being greater than the friction between the tickets.

[0034] Further, a damping roller 603 opposite to the bill rubbing rubber roller 601 may be provided on the damping member 602. The damping roller 603 may be columnar and may be fixed to the damping member to facilitate the passage of bills.

[0035] The printing conveying channel 4 is located behind the ticket rubbing rubber roller 601 and may include a thermal printer, i.e., a printing mechanism 402, a transmission rubber roller, and a corresponding driving mechanism. The transmission rubber roller is used to realize the conveying movement of the ticket, and the driving mechanism is used to provide power. The printing conveying channel 4 is used to print corresponding marks (such as the word "return ticket") on the ticket. Figure 5 and Figure 6 A recycling box 403 can be provided below the second end of the printing conveying passage 4 for storing printed bills. The recycling box 403 can be a detachable structure for storing the bills recycled after printing and neatly stacking them.

[0036] On the basis of the above embodiment, further, a ticket blocking assembly 7 is provided between the second end of the cache conveying channel 3 and the ticket rubbing mechanism 6, and the ticket blocking assembly 7 includes a baffle 701 and a driving member 702, and the driving member 702 is used to drive the baffle 701 to extend upward from the cache conveying channel 3 and retract downward to below the cache conveying channel 3.

[0037] Before the user completes inserting the ticket through the transceiver mechanism 1, the baffle 701 can be raised, and the baffle 701 extends out of the buffer conveying channel 3 to play a blocking role at the second end of the buffer conveying channel 3. Under the blocking of the baffle 701, at least one ticket inserted by the user can be temporarily stacked on the buffer conveying channel 3. After the user completes voting, it is necessary to confirm the business operation of at least one ticket on the buffer conveying channel 3. When the user confirms to perform the corresponding business operation, the baffle 701 can be dropped, and then the at least one ticket is sequentially conveyed backward through the ticket rubbing mechanism 6.

[0038] The ticket blocking component 7 can be provided to temporarily store at least one ticket on the buffer conveying channel 3 for the user to make final confirmation, which is beneficial to improving the flexibility of the terminal service equipment, avoiding user misoperation and improving efficiency.

[0039] Furthermore, the driving member 702 in the ticket blocking assembly 7 is an electromagnet, and the baffle 701 is an iron plate; the electromagnet can be arranged below the second end of the buffer conveying channel 3, and the iron plate is connected to the top of the electromagnet through an elastic member. When the initial elastic member is in a naturally extended state, the iron plate can extend out of the buffer conveying channel 3 to play a blocking role. When the iron plate needs to fall, the electromagnet can be energized to attract the iron plate to fall. The driving member 702 can also be other structures that can provide driving power for up and down movement, and there is no specific limitation.

[0040] On the basis of the above embodiment, further, a return channel 5 is provided at the first end of the cache conveying channel 3, the first end of the return channel 5 is close to the cache conveying channel 3, and the second end of the return channel 5 is connected to the ticket outlet 102, and the return channel 5 is used to return the ticket on the cache conveying channel 3 to the ticket outlet 102 when the user's confirmation information is a cancellation operation.

[0041] The first end of the ticket entry channel 2 can be connected to the ticket entry port 101 of the transceiver 1; the second end of the return channel 5 is connected to the ticket exit port 102 of the transceiver 1. When at least one ticket is stored in the cache conveying channel 3, a confirmation operation message can be sent to the user. If the user changes his mind at this time, the corresponding business operation can be canceled. If the user cancels the business operation at this time, the cache conveying channel 3 can be controlled to convey in the reverse direction, and at least one ticket can be conveyed to the return channel 5 at the same time. Then the return channel 5 is operated to convey the ticket to the ticket exit port 102, and the user can take the ticket again. Setting the return channel 5 can greatly improve the use flexibility and intelligence level of the terminal service device, which is conducive to improving the user experience.

[0042] Furthermore, in this embodiment, a one-way conveying structure is provided inside the ticket outlet 102, which is used to discharge the bill from the ticket outlet 102 and prevent the bill from being inserted from the ticket outlet 102. Specifically, the one-way conveying structure may include a baffle provided inside the ticket outlet 102, the top of the baffle being rotatable, and a baffle being provided on the side of the baffle away from the ticket outlet 102, the baffle being used to limit the baffle from rotating toward the side away from the ticket outlet 102, so as to prevent the bill from being inserted from the ticket outlet 102. Because the baffle can rotate toward the ticket outlet 102, when the bill is discharged, the bill can push the baffle to rotate toward the ticket outlet 102, so that the bill can be discharged smoothly.

[0043] On the basis of the above embodiment, further, a first pressing structure is provided above the buffer conveying channel 3 near the first end, and the first pressing structure is used to press down one end of the bill near the return channel 5 when the user's confirmation information is a cancellation operation so that the bill corresponds to the return channel 5. When the user confirms the cancellation operation and needs to return the bill, the first pressing structure can be driven to move downward to press down the end of the bill, which can prevent the end of the bill from tilting up and ensure that the bill can smoothly enter the return channel 5.

[0044] On the basis of the above embodiment, further, a second pressing structure is provided above the second end of the buffer conveying channel 3 and the first pressing structure, and the second pressing structure is used to press the bill downward when the user's confirmation information is a cancel operation. The second pressing structure cooperates with the first pressing structure, and when the bill needs to be returned, the two can press different parts of the bill to ensure that the bill can smoothly enter the return channel 5.

[0045] refer to Figure 2 and Figure 3 In this embodiment, the first clamping structure can be a crank rocker structure 303, which includes a crank 3032 rotatably fixed above the cache conveying channel 3 and a rocker 3033 rotatably connected to the crank 3032, and a clamping wheel 3031 is connected to the bottom of the rocker 3033. The clamping wheel 3031 is used to press the end of the bill close to the return channel 5 downward by rotating the crank 3032 when the user confirms the cancellation operation so that the bill corresponds to the return channel 5.

[0046] The crank 3032 may specifically include a rotating shaft and a connecting rod. The rotating shaft is rotatably arranged, one end of the connecting rod is fixedly connected to the rotating shaft, and the other end of the connecting rod is rotatably connected to the rocker 3033. By driving the rotating shaft to rotate, the rocker 3033 can be driven to move up and down, and then the bill can be pressed by the downward movement of the rocker 3033.

[0047] In this embodiment, the second clamping structure may be a cam structure 304. By driving the rotation of the cam structure 304, the height of the lowest point of the cam structure 304 can be adjusted, thereby providing a downward clamping force. Furthermore, the first clamping structure and the second clamping structure may also be a gear rack structure, a lead screw nut structure, or a guide rail slide structure, etc., in order to achieve up and down movement and controllable displacement, without specific limitation.

[0048] Specifically, taking the first clamping structure as an example, when the first clamping structure is a gear rack structure, a meshing gear and a rack can be set, and the rack can be movably set in the vertical direction. By driving the gear to rotate, the rack can be driven to move up and down, and downward pressure can be provided by the rack. When the first clamping structure is a screw nut structure, a screw can be set in the vertical direction, and the nut is fixedly set. By driving the screw to rotate, the screw can be moved up and down, and downward pressure can be provided by the screw. When the first clamping structure is a guide rail slide, the guide rail is set vertically, and downward pressure is provided by the downward movement of the slide.

[0049] Furthermore, rollers may be provided at the bottom of the movable parts of the first pressing structure and the second pressing structure to contact the bill, so as to realize the smooth movement of the bill.

[0050] On the basis of the above embodiments, further, the ticket feeding conveying channel 2, the cache conveying channel 3, the printing conveying channel 4 and the return channel 5 respectively include at least one group of rubber roller assemblies, each group of rubber roller assemblies includes correspondingly arranged active rubber rollers and driven rubber rollers, the active rubber rollers are transmission-connected to the driving structure, and the active rubber rollers and the driven rubber rollers are both elastic floating structures.

[0051] The conveying channel is formed by a rubber roller assembly. Each conveying channel may include one or more rubber roller assemblies. The space between the active rubber roller and the driven rubber roller is the bill conveying channel. The bill moves between the active rubber roller and the driven rubber roller for conveying. The active rubber roller can rotate under the drive of the driving structure to provide power for the bill conveying movement. The driven rubber roller does not need to be connected to the driving structure and can be rotated.

[0052] The active rubber roller and the driven rubber roller are set to an elastic floating structure, so that the active rubber roller and the driven rubber roller can have an up and down floating amount respectively, which can adapt to different bill thicknesses and improve the flexibility and applicability of the conveying channel.

[0053] Furthermore, in this embodiment, the elastic floating structures of the active rubber roller and the driven rubber roller are similar. Taking the elastic floating structure of an active rubber roller as an example, the active rubber roller includes a fixed shaft and a rubber roller rotatably mounted on the fixed shaft; the two ends of the fixed shaft can be movably connected to a bracket up and down respectively. Specifically, a guide rail can be arranged on the bracket along the vertical direction, and the two ends of the fixed shaft are movably connected to the guide rails on both sides. An elastic member can be arranged on the side of the active rubber roller away from the corresponding driven rubber roller, which can be a spring or a spring. The elastic member presses against the driven rubber roller and generates a thrust toward the corresponding driven rubber roller. Thereby, the active rubber roller has a certain floating space.

[0054] On the basis of the above embodiments, further, referring to Figure 2 The ticket feeding conveying channel 2, the buffer conveying channel 3, the printing conveying channel 4 and the return channel 5 are respectively provided with a support plate 302 between the active rubber roller and the driven rubber roller along the conveying direction, and the support plate 302 is provided with an opening at a position corresponding to the rubber roller assembly. Specifically, the support plate 302 can be fixedly connected to the fixed shaft of the bracket or the rubber roller. The support plate 302 is used to support the bill between the active rubber roller and the driven rubber roller. An opening is provided at a position corresponding to the support plate 302 and the rubber roller assembly, so that the support plate 302 does not affect the contact between the rubber roller assembly and the bill, thereby ensuring that the rubber roller assembly can realize the transportation and movement of the bill.

[0055] The support plate 302 of the buffer conveying channel 3 is an elastic floating structure, so that the buffer conveying channel 3 can adapt to different numbers of bills and improve flexibility.

[0056] Furthermore, in this embodiment, the active rubber roller in the buffer conveying channel 3 is arranged above the driven rubber roller, and the support plate is connected with an elastic member at the bottom between the active rubber roller and the driven rubber roller. The bill on the bill feeding conveying channel 2 falls onto the support plate of the buffer conveying channel 3, and the active rubber roller above the bill can provide power for bill conveying by rotating.

[0057] Furthermore, the active rubber rollers in each conveying channel can be connected by multiple synchronous belts according to the actual position relationship. An active rubber roller connected by a synchronous belt can be driven by a drive motor, which can reduce the number of drive motors arranged.

[0058] On the basis of the above embodiments, further, referring to Figure 1 A first support plate 503 and a second support plate 504 are provided between two adjacent rubber roller assemblies of the return channel 5. The first support plate 503 is fixedly connected to the rubber roller assembly near the first end of the return channel 5 along the conveying direction of the return channel 5. One end of the second support plate 504 is rotatably connected to the rubber roller assembly near the second end of the return channel 5. The other end of the second support plate 504 is in a naturally drooping state between the two rubber roller assemblies, and a collection box 505 is provided below the second support plate 504.

[0059] The second support plate 504 is between the two rubber roller assemblies, and there is a gap between the second support plate 504 and the rubber roller assembly near the second end of the return channel 5. Because the other end of the second support plate 504 is in a naturally drooping state between the two rubber roller assemblies, the support plate between the two rubber roller assemblies is disconnected and not continuous. Through the arrangement of the first support plate 503 and the second support plate 504, the return channel 5 can only realize one-way transportation.

[0060] That is, when the return channel 5 transports the bill from the first end to the second end, when the bill enters the rubber roller assembly near the first end of the return channel 5, it will move along the first support plate 503 on the first support plate 503, and the bill will cross the disconnected portion between the first support plate 503 and the second support plate 504. When the bill enters the rubber roller assembly near the second end of the return channel 5, it will press down one end of the second support plate 504, thereby driving the second support plate 504 to rotate and connect with the first support plate 503, so that the bill can be smoothly transported to the second end of the return channel 5.

[0061] When the return channel 5 transports the bill from the second end to the first end, when the bill enters the rubber roller assembly near the second end of the return channel 5, because the second support plate 504 is not connected to the rubber roller assembly, the bill cannot continue to move along the return channel 5, and the bill will fall into the collection box 505 from the gap between the second support plate 504 and the rubber roller assembly.

[0062] The arrangement of the first support plate 503 and the second support plate 504 of the return channel 5 can form an overtime recovery mechanism. When the ticket returned to the ticket outlet 102 is not taken away after the timeout, the return channel 5 can be driven to suck the ticket back to the return channel 5, and when the ticket reaches the second support plate 504, the ticket is sent from the second support plate 504 to the overtime collection box 505.

[0063] On the basis of the above embodiments, further, a first detection unit 801 is provided at the first end of the ticket feed conveying channel 2, and a second detection unit 802 is provided at the second end of the ticket feed conveying channel 2; a third detection unit 803 is provided at the first end of the cache conveying channel 3; a fourth detection unit 804 is provided at the first end of the print conveying channel 4, and a fifth detection unit 805 is provided at the second end of the print conveying channel 4; a sixth detection unit 806 is provided at the second end of the return channel 5.

[0064] When the first detection unit 801 detects a ticket, the ticket delivery channel 2 can be controlled to start moving; when the second detection unit 802 detects a ticket, the ticket delivery channel 2 can be controlled to stop moving, and service selection information is sent to the user, and the user can select the corresponding service to be performed. After the user selects, the ticket delivery channel 2 can be started to deliver the ticket to the cache delivery channel 3. When the third detection unit 803 detects a ticket, the cache delivery channel 3 can be controlled to move; when the third detection unit 803 does not detect a ticket, it means that the ticket has been completely moved to the second end of the cache delivery channel 3, and the cache delivery channel 3 can be controlled to stop moving; and a confirmation message is sent to the user for the user to confirm whether to perform the service operation.

[0065] When the user confirms to carry out the business operation, the cache conveying channel 3 is started to convey the tickets one by one to the printing conveying channel 4. The movement of the printing conveying channel 4 can be controlled according to whether the fourth detection unit 804 detects the ticket; when the fifth detection unit 805 detects the ticket, the ticket rubbing mechanism 6 can be controlled to stop running to prevent the next ticket from entering the printing conveying channel 4 and affecting the printing of the previous ticket; in addition, when the fifth detection unit 805 cannot detect the ticket or the printing mechanism 402 feedbacks that the printing is completed, the ticket rubbing mechanism 6 can be controlled to run and convey the next ticket to the printing conveying channel 4. A detection unit can also be set at the second end of the cache conveying channel 3, and the cache conveying channel 3 is controlled to stop running when the detection unit detects that there is no ticket on the cache conveying channel 3. The sixth detection unit 806 is used to detect whether there is a leftover ticket at the ticket outlet 102.

[0066] On the basis of the above embodiment, further, a magnetic reading mechanism 204 and an image scanning mechanism 205 are provided on the ticket feeding conveying channel 2, the magnetic reading mechanism 204 is used to read and identify the magnetic information of the bill, and the image scanning mechanism 205 is used to obtain and identify the image information of the bill; the ticket feeding conveying channel 2 is used to convey the bills with qualified magnetic information and image information to the second end, and convey the bills with at least one of unqualified magnetic information and image information to the first end and return them to the ticket entrance 101.

[0067] The ticket magnetic reading mechanism 204 and the image scanning mechanism 205 are used to verify the magnetic information of the ticket entering from the ticket entrance 101. If it is incorrect, the ticket conveying channel 2 moves in the reverse direction to discharge the ticket from the ticket entrance 101; the image scanning mechanism 205 can use the CIS image scanning function to distinguish between dirty and damaged tickets and cut-edge tickets. If it is a dirty or cut-edge ticket, the ticket conveying channel 2 moves in the reverse direction to discharge the ticket from the ticket entrance 101. Only when the magnetic reading and image scanning mechanisms 205 both determine that the ticket is a legal ticket, that is, a qualified ticket, the ticket conveying channel 2 will convey the ticket to the buffer conveying channel 3 in the forward direction.

[0068] On the basis of the above embodiments, further, this embodiment provides a ticketing operation method based on the ticketing terminal service device described in any of the above embodiments, and the ticketing operation method includes: performing magnetic information and image information identification on the incoming ticket at the ticket entrance 101, and conveying the ticket identified as a qualified ticket forward; returning the ticket identified as an unqualified ticket to the ticket entrance 101. When the ticket is conveyed to the second end of the ticket conveying channel 2, the ticket is conveyed to the cache conveying channel 3 after the user confirms the ticket; this step can be used for the user to confirm the inserted ticket information, and then convey the ticket to the cache conveying channel after the user confirms the ticket information. This step can also set a ticket return process, that is, when the user finds that the inserted ticket is incorrect, he can choose to return the ticket when confirming the ticket, and the ticket conveying channel will return the ticket to the ticket entrance 101 to avoid user misoperation.

[0069] After conveying multiple bills to the cache conveying channel 3 in sequence according to the above operation steps, the user is requested to confirm the bill again; if the user confirms to perform the business operation, the bill is conveyed to the printing conveying channel 4 in sequence for label printing and recycling; if the user confirms to cancel the business operation, the bill is returned to the ticket outlet 102 through the return channel 5; if the bill is detected at the ticket outlet 102 after the preset time, the bill is conveyed through the return channel 5 and recycled.

[0070] Among them, if the user confirms to carry out the business operation, the single ticket will be conveyed to the printing and conveying channel 4 in turn for identification printing and recycling, which specifically includes: running the printing and conveying channel 4 for a preset time after the ticket is detected at the entrance of the printing and conveying channel 4; when the ticket is detected at the exit of the printing and conveying channel 4, controlling the ticket rubbing mechanism 6 to stop running; when printing is completed or the ticket is not detected at the exit of the printing and conveying channel 4, controlling the ticket rubbing mechanism 6 to re-run; when the ticket is not detected at the exit of the printing and conveying channel 4, controlling the printing and conveying channel 4 to stop running.

[0071] Because the printing mechanism 402 is spaced from the entrance of the printing conveying passage 4, the printing conveying passage 4 is controlled to operate only after a preset time after the bill arrives at the entrance, that is, the printing conveying passage 4 is operated only when the bill arrives at the printing mechanism 402. When the printing conveying passage 4 is operating, there is a bill between the printing mechanism 402 and the printing conveying passage 4, so that the printing mechanism 402 is prevented from directly contacting the passage, specifically, the printing mechanism 402 is prevented from directly contacting the printing rubber roller, thereby reducing the wear of the printing mechanism 402 and increasing the service life.

[0072] On the basis of the above embodiments, further, referring to Figure 1A ticket feeding conveying channel 2 in a ticket terminal service device includes a first rubber roller assembly 201, a second rubber roller assembly 202 and a third rubber roller assembly 203 arranged in sequence from front to back; the active rubber rollers in the first rubber roller assembly 201, the second rubber roller assembly 202 and the third rubber roller assembly 203 can be connected by synchronous belt transmission. The buffer conveying channel 3 includes a ticket rubbing auxiliary rubber roller assembly 301 arranged between the third rubber roller assembly 203 and the ticket rubbing rubber roller 601, and the active rubber roller in the ticket rubbing auxiliary rubber roller assembly 301 and the ticket rubbing rubber roller 601 are connected by synchronous belt transmission. The printing conveying channel 4 includes a printing rubber roller assembly 401; the return channel 5 and the ticket feeding conveying channel 2 can share the active rubber roller of the third rubber roller assembly 203, the ticket feeding conveying channel 2 can be arranged above the active rubber roller of the third rubber roller assembly 203, and the return channel 5 can be arranged below the active rubber roller of the third rubber roller assembly 203. The return channel 5 also includes a fourth rubber roller assembly 501 and a fifth rubber roller assembly 502. The active rubber rollers of the fourth rubber roller assembly 501 and the fifth rubber roller assembly 502 are drivingly connected to the active rubber rollers in the ticket feeding and conveying channel 2 via synchronous belts.

[0073] refer to Figure 2 and Figure 3 , the first clamping structure is a crank rocker structure 303, and the second clamping structure is a cam structure 304. The cam structure 304 specifically includes an eccentric wheel assembly, which includes a rotating shaft 3041 and an eccentric wheel 3042 eccentrically sleeved on the rotating shaft 3041, and the eccentric wheel 3042 is arranged on the side or upper side of the active rubber roller of the ticket rubbing auxiliary rubber roller assembly 301; the eccentric wheel 3042 can act on the active rubber roller during the rotation process, and the active rubber roller is used to press the bill downward. By driving the rotating shaft 3041 to rotate, the eccentric wheel 3042 can reach the lowest position, at which time the eccentric wheel 3042 can be pressed on the active rubber roller, thereby pressing the active rubber roller downward, and the bill is pressed downward by the active rubber roller. Further, the crank of the first clamping structure and the rotating shaft of the second clamping structure can be connected through a synchronous belt transmission.

[0074] The terminal service device also includes a driving mechanism, which includes a reading magnetic motor 901 below the return channel 5, a ticket rubbing motor 902 located behind the collection box 505, a printing motor 903 below the printing and conveying channel 4, and a DC motor 305 for driving the first clamping structure and the second clamping structure to operate.

[0075] The reading magnetic motor 901 drives the ticket feeding channel 2, namely the first rubber roller assembly 201, the second rubber roller assembly 202 and the third rubber roller assembly 203, to convey the legal tickets to the buffer area; the reading magnetic motor 901 also drives the return channel 5, namely the fourth rubber roller assembly 501 and the fifth rubber roller assembly 502, wherein the fifth rubber roller assembly 502 is located near the ticket return port.

[0076] The ticket rubbing motor 902 is located behind the collecting box 505, driving the ticket rubbing rubber roller 601 of the ticket rubbing mechanism 6 and the active rubber roller of the auxiliary ticket rubbing rubber roller 601 assembly to rotate simultaneously. When the third detection unit 803 detects the ticket, the ticket rubbing motor 902 starts to drive the auxiliary ticket rubbing rubber roller to send the ticket to the buffer area; the printing motor 903 is located behind the ticket rubbing rubber roller 601. When the separated ticket is detected, the printing motor 903 rotates to print the ticket; the printing motor 903 is located below the tail end of the device and drives the printing rubber roller. When the detection unit at the front end of the printing rubber roller detects the separated ticket, the printing motor 903 drives the printing rubber roller to transmit the ticket and print it at the same time.

[0077] refer to Figure 3 and Figure 4 , the DC motor 305 is connected to the eccentric wheel assembly through a synchronous belt, the eccentric wheel assembly is connected to the first clamping structure through a synchronous pulley, and the first clamping structure allows the clamping wheel 3031 to be lifted up and down through the crank rocker structure 303; the eccentric wheel assembly controls the start and stop of the DC motor 305 through the optical coupling baffle. That is, one end of the rotating shaft 3041 of the eccentric wheel assembly can be connected to the baffle 3043 to rotate integrally, and optical coupling switches 3044 can be set on both sides of the baffle 3043. When the baffle 3043 is just blocked by the opposite optical coupling, the ticket rubbing wheel assembly is in a lifted state. When the DC motor 305 drives the rotating shaft 3041 to rotate so that the baffle 3043 rotates just out of the optical coupling, the eccentric wheel assembly is in a pressed state, and the first clamping structure is also in a pressed state. At this time, the action of returning the tickets in the buffer area is performed, and the DC motor 305 can be controlled to stop running.

[0078] The terminal service device also includes a control unit, which is connected to each component of the driving mechanism and each detection unit respectively, and is used for comprehensively controlling the operation of the entire device.

[0079] On the basis of the above embodiment, further, this embodiment provides a ticket terminal service device for self-service ticket refund. The device includes a transceiver mechanism 1 (which can be made by plastic mold opening) for receiving and refunding tickets, and the ticket inlet 101 must limit the entry of a single ticket to prevent two tickets from being inserted at one time; the inner side of the ticket inlet 101 of the transceiver mechanism 1 is provided with a first detection unit 801, which can be set on the ticket inlet conveying channel 2, and the ticket inlet conveying channel 2 is connected to a driving unit, and the first detection unit 801 is connected to the driving unit to control the start and stop of the driving unit according to the detection result obtained by the first detection unit 801.

[0080] The ticket magnetic reading and image scanning mechanism is used to read the magnetic information of the ticket, identify the magnetic information, read the image to identify the dirty ticket and the cut ticket; the ticket buffer mechanism is used to temporarily store the legal tickets, no more than 7 tickets at a time; the ticket separation and printing mechanism 402, that is, the ticket rubbing mechanism 6, is used to separate the multiple tickets in the buffer area into single tickets and discharge them in sequence; the ticket return mechanism is used to return the legal tickets temporarily stored in the buffer area when terminating the ticket refund, and the ticket is sent to the ticket outlet 102 through the return channel 5; the timeout recovery mechanism is used to recover the ticket to the timeout collection box 505 when the ticket returned to the ticket return outlet is not taken after the timeout.

[0081] Through the device of this embodiment, the user can perform the ticket refund operation by himself. The user can sequentially put no more than 7 tickets to be refunded into the ticket receiving and sending mechanism 1, and perform the refund of multiple tickets through a single process operation. The user puts the first ticket into the ticket entrance. At this time, the first detection unit 801 behind the ticket entrance detects the ticket. The first detection unit 801 connects to the control unit to start the driving structure of the ticket feeding conveying channel 2, and the ticket is sucked into the ticket feeding conveying channel 2 and sent to the magnetic reading mechanism 204 and the image scanning mechanism 205 for ticket identification. When the magnetic information of the ticket is correct and the ticket information is a legal ticket, the user confirms the information and puts the ticket into the buffer area. Then the user repeats the operation of the first ticket to send the remaining tickets into the buffer area in sequence. Then the user confirms again on the operation page. When the user chooses to refund the ticket, the control unit starts the paper feeding mechanism to separate and print the ticket. At this time, the printing conveying channel 4 is started by the detection unit to print the ticket. The ticket passes through the thermal printer of the printing mechanism 402 to print the refund mark, serial number and other information for maintenance personnel to distinguish. The printed ticket is sent to the invalid ticket recovery box 403; when the user confirms the ticket in the cache area, the refund is cancelled. At this time, the control unit activates the first clamping structure and the second clamping structure, and then activates the cache conveying channel 3 to send the ticket to the return channel 5, and then transmits the ticket to the ticket outlet 102. At this time, the user takes all the tickets away. If the user forgets to take the ticket at this time, after a certain period of time, the control unit will activate the return channel 5, suck the ticket into the timeout non-taken mechanism, and recycle the ticket into the timeout non-taken collection box 505.

[0082] Furthermore, in this embodiment, the ticket magnetic reading and image scanning mechanism 205 is located behind the ticket entrance, including a magnetic reading detection unit, a magnetic reading head 2041 and a CIS scanning module. When the ticket is inserted into the ticket entrance and the entrance detection unit detects that there is a ticket, the control unit drives the magnetic reading motor 901 to rotate forward to suck the ticket into the ticket conveying channel 2. When the ticket reaches the magnetic reading detection unit, the control unit starts to control the magnetic reading head 2041 to start forward magnetic reading, and the CIS scanning module starts image scanning. At this time, the magnetic reading information is correct, the image comparison is successful, the ticket is judged to be a legal ticket, and the ticket is sent to the buffer area; when the scanned image comparison is correct and the magnetic reading is wrong, the magnetic reading motor 901 drives the transmission mechanism in the reverse direction to perform reverse magnetic reading. When the magnetic reading is still incorrect, forward magnetic reading is performed again, and magnetic reading is repeated up to three times; when the magnetic information and image comparison are correct, it is considered a legal ticket and sent to the buffer area; when there is any error in the image comparison and the magnetic reading information, it is considered an illegal ticket, and the magnetic reading motor 901 reverses to discharge the ticket.

[0083] Furthermore, in the present embodiment, the ticket caching mechanism is located after the third rubber roller assembly 203 and after the magnetic reading and image scanning mechanism 205, and is used to temporarily stack legal tickets and stack them neatly, including a third detection unit 803 at the cache entrance, a ticket rubbing assembly, a support plate assembly, a cache exit detection unit 807, an electromagnet ticket blocking assembly 7, and a ticket rubbing motor 902, the ticket rubbing wheel assembly includes a ticket rubbing auxiliary rubber roller assembly 301; the ticket blocking assembly 7 includes an electromagnet and a ticket blocking plate, etc.; the support plate assembly is supported by a spring and is naturally pressed down when multiple tickets are stacked; the third detection unit 803 is located at the edge of the support plate assembly close to the ticket input end, and is used to determine the position of the ticket. When it is detected that the ticket is out of the third detection unit 803, the ticket rubbing motor 902 driven by the ticket rubbing motor stops rotating, and the ticket is stacked at the second end of the cache conveying channel 3. When the third detection unit 803 at the cache entrance detects a ticket, the control unit drives the ticket rubbing motor 902 to drive the ticket rubbing auxiliary rubber roller to rotate and transmit the ticket backward. When the cache entrance detection unit fails to detect the ticket, the ticket rubbing motor 902 stops rotating after the ticket encounters the baffle 701. When the number of tickets increases, the spring plate assembly is pressed down to ensure that the tickets are temporarily stored neatly.

[0084] Furthermore, in this embodiment, the ticket separation and printing mechanism 402 is located behind the buffer area, the ticket rubbing mechanism 6, the electromagnet ticket blocking assembly 7, the ticket rubbing motor 902, the damping assembly, the fourth printing detection unit 804, the printing rubber roller, the thermal printer, the printing motor 903, and the fifth printing outlet detection unit 805. When the ticket is determined to be refunded, the control unit controls the electromagnet ticket blocking assembly 7 to drop the baffle 701. At this time, the ticket rubbing motor 902 rotates forward to drive the ticket rubbing rubber roller 601. At this time, the ticket rubbing auxiliary rubber roller transmits the ticket forward. When the ticket encounters the ticket rubbing rubber roller 601, the damping member 602 below is due to resistance. The force difference separates the ticket into single tickets and transmits them forward. When the ticket encounters the fourth printing detection unit 804, the control unit will delay driving the printing motor 903. When the ticket just touches the printing rubber roller, the thermal print head will print the ticket return identification information and then send the ticket to the waste ticket recycling box 403. When the fifth printing outlet detection unit 805 detects the ticket, the ticket rubbing motor 902 stops rotating. When the printing outlet detection unit detects that the ticket printing is completed, the ticket rubbing motor 902 continues to rotate and continues the above-mentioned ticket separation and printing process. When the cache outlet detection unit 807 detects that there is no ticket in the cache area, printing is completed.

[0085] Furthermore, in this embodiment, the ticket return mechanism is used to return the ticket in the buffer area, including a return channel 5 (a third rubber roller assembly 203, a fourth rubber roller assembly 501, and a fifth rubber roller assembly 502), a read magnetic motor 901, an eccentric wheel assembly, a first clamping structure, and a ticket return outlet 102. When the ticket is in the buffer area and the user cancels the ticket refund service, the ticket in the buffer area needs to be returned to the user. At this time, the control unit drives the DC motor 305 to rotate through the synchronous belt connected to the eccentric wheel assembly. At the same time, the eccentric wheel assembly is connected to the crank rocker structure 303 through the synchronous belt and rotates simultaneously. At this time, the eccentric wheel assembly reaches the lower limit position, and the clamping wheel 3031 also reaches the lowest limit position at the same time. Then, the ticket rubbing motor 902 reverses to transmit the ticket to the return channel 5. When the third detection unit 803 at the cache entrance detects the ticket, the read magnetic motor 901 drives the third rubber roller assembly 203, the fourth rubber roller assembly 501, and the fifth rubber roller assembly 502 to send the ticket to the ticket return outlet.

[0086] Furthermore, in this embodiment, the timeout recovery mechanism includes the sixth detection unit 806 at the exit, the reading magnetic motor 901, the fourth rubber roller assembly 501, and the fifth rubber roller assembly 502. When no one takes the ticket at the return ticket outlet 102, after a certain period of time, the sixth detection unit 806 at the exit drives the reading magnetic motor 901 through the control unit to drive the fourth rubber roller assembly 501 and the fifth rubber roller assembly 502 to reverse and transport the ticket back to the return channel 5. When the ticket reaches the second support plate 504 between the third rubber roller assembly 203 and the fourth rubber roller assembly 501, the ticket is transferred from the bottom of the second support plate 504 to the collection box 505.

[0087] In addition to the above mechanisms, the terminal service device in this embodiment also includes a switch mechanism 10 and a circuit board 11, wherein the circuit board 11 is connected to each electrical device in the above mechanism and transmits signals to each electrical device, and each control circuit is provided on the circuit board 11 to form a control unit. The switch mechanism 10 can be used to control the opening and closing of the entire device.

[0088] Through the device of this embodiment, passengers can refund or change no more than 7 magnetic medium tickets at the same time, which improves the efficiency of refunding and changing multiple tickets. The device will make the railway ticket change business self-service, greatly improve work efficiency, and reduce the labor intensity of station staff.

[0089] The ticket terminal service device provided in the above embodiments solves the problem in the prior art that most ticket refund and ticket change operations need to be completed by ticket staff, resulting in a heavy workload. Through the device of this embodiment, users can perform ticket refund and ticket change operations by themselves, without the need for ticket staff to operate, thereby reducing the labor intensity of ticket staff. In addition, the refund and ticket change tickets put into the device, as well as the regenerated ticket change tickets, can be processed by a set of mechanisms, thereby simplifying the structure of the device.

[0090] Furthermore, the terminal service device can be used for ticket refunds or changes, as well as for other ticket operations, such as the recovery of bus cards, IC cards, certificates or other types of tickets with magnetic information inside, etc. The specific application is not limited.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
