Description

Technical Field

[0001] This utility model belongs to the technical field of highway equipment, and in particular relates to a card reading and writing transmission mechanism and a card issuing machine. Background Technology

[0002] With economic development and a rapid increase in car ownership, the flow of goods, people, and commodities has increased dramatically. Highways have become a crucial mode of transportation and a vital infrastructure project. Against the backdrop of rapidly expanding highway mileage, the demands on toll management, traffic control, and administration are also rising, making it increasingly urgent to improve transportation efficiency and reduce maintenance costs.

[0003] Therefore, at the entrances of highways, more and more toll stations are installing self-service card dispensing devices so that drivers can take cards themselves and pass through quickly without human intervention.

[0004] However, automatic card dispensers are typically installed on safety islands at level crossings. To prevent the machine from scraping against passing vehicles, it is usually recessed about 15cm inward from the edge of the safety island. This causes the card dispenser's dispensing slot to also be recessed by about 15cm, directly increasing the distance drivers need to reach to retrieve their cards and placing higher demands on their driving skills. Although drawer-type self-service card dispensers have emerged, the problem of the card being dispensed from inside the drawer still exists, resulting in the card being dispensed from the back and inconvenient for users to retrieve their cards. Utility Model Content

[0018] The number of telescopic guide rails corresponds one-to-one with the number of telescopic guide rail brackets, and one end of each telescopic guide rail is fixed to the telescopic guide rail bracket, while the other end of each telescopic guide rail is fixed to the end of the outer frame near the bayonet panel.

[0019] The number of telescopic sliders corresponds one-to-one with the number of telescopic guide rails, and the telescopic sliders are sleeved on the telescopic guide rails and fixedly connected to the support side plate.

Detailed Implementation

[0037] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0038] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0039] like Figures 1 to 3 As shown, this embodiment of the utility model provides a card reading and writing transmission mechanism, including: a card transmission device, a supporting side plate 2, a slot panel 11 with a slot 20 capable of accommodating cards, and a telescopic device (e.g., made of...). Figure 1 (It consists of a telescopic drive motor 7 and a telescopic component 8).

[0040] The card transmission device is mounted on the support side plates 2 on both sides, with one end of the card transmission device close to the slot panel 11, so as to transmit the card in the direction of the slot panel 11.

[0041] The telescopic device is connected to the support side plate 2 and the bayonet panel 11 respectively, so that the card transmission device on the support side plate 2 and the bayonet panel 11 can be extended and retracted simultaneously through the telescopic device.

[0042] For example, such as Figure 1 and Figure 3 As shown, the card read / write transmission mechanism may also include an external frame 1.

[0043] The card transfer device is located at one end away from the bayonet panel 11 and the support side plate 2 is located at one end away from the bayonet panel 11 within the outer frame 1.

[0044] The bayonet panel 11 is located outside the outer frame 1.

[0045] The telescopic device is installed on the outer frame 1.

[0046] For example, such as Figure 1 and Figure 2 As shown, the card conveying device may include: a conveyor belt 4, a drive roller 5, a passive roller 6, and a conveyor belt drive motor 3.

[0047] The conveyor belt 4 is positioned between the drive roller 5 and the driven roller 6, and the conveyor belt drive motor 3 drives the conveyor belt 4 to rotate through the drive roller 5 and the driven roller 6.

[0048] For example, such as Figure 1 and Figure 2 As shown, card reading and writing antenna mounting slots 10 are also provided on both sides of the support side plate 2.

[0049] A card reading and writing antenna base plate (not shown in the figure) is provided between the two card reading and writing antenna base plate slots 10.

[0050] The card reader / writer antenna base plate and the card reader / writer antenna 9 located on the card reader / writer antenna base plate are located below the upper part of the conveyor belt 4.

[0051] Combination Figure 1 -to Figure 3 As shown, the working process of the card read / write transmission mechanism in this embodiment is as follows:

[0052] First, place the card 12 on the conveyor belt 4. Driven by the conveyor belt drive motor 3, the active shaft roller 5 and the passive shaft roller 6 drive the conveyor belt 4 to rotate, thereby moving the card 12 toward the bayonet panel 11.

[0053] During the movement, the card 12 passes under the card reading and writing antenna 9 below the upper conveyor belt in the conveyor belt 4, thereby realizing the reading and writing operation of the card 12.

[0054] Afterwards, the card 12 continues to move toward the slot panel 11 along with the movement of the conveyor belt 4 until the card 12 extends a certain distance from the slot 20 of the slot panel 11. At this time, the support side plates 2 on both sides of the conveyor belt 4, the entire card transmission device, and the slot panel 11 can be driven by the telescopic device to extend toward the direction of the slot panel 11, so as to realize the user's card retrieval.

[0055] In order to ensure that the card 12 is not obstructed during transmission, the distance between the support side plates 2 on both sides of the conveyor belt 4 can exceed a preset value.

[0056] The preset value can be determined based on the width of the card 12 that needs to be transmitted. Taking a card 12 width of 60mm as an example, the preset value can be 63mm, 65mm, etc.

[0057] To ensure optimal reading and writing performance of the card reader / writer antenna 9, the distance between the card reader / writer antenna 9 and the lower part of the upper conveyor belt 4 can be limited to a preset distance. This preset distance can be determined based on the specific card reader / writer antenna; for example, a preset distance of 5mm is possible.

[0058] In order to make it easier for users to retrieve their cards, combined with Figure 3 As shown, a slot 20 for card 12 can be provided on the slot panel 11, and a button 21 can be installed below the slot 20. For example, the button 21 can be a mushroom-shaped button.

[0059] In this embodiment of the invention, a card transmission device is mounted on the support side plates on both sides, with one end of the card transmission device close to the card slot panel. The card can be transmitted towards the card slot panel via this device. Then, a telescopic device connects to both the support side plates and the card slot panel, allowing both the card transmission device and the card slot panel to extend and retract simultaneously. This allows the card transmission device and the card slot panel to extend and retract as a single unit during card dispensing, enabling the card to extend beyond the card slot on the card slot panel. This further increases the card extension distance, improving the problem of the card dispenser's rearward dispensing position and the inconvenience for users to retrieve their cards. Furthermore, the open card transmission device, composed of a conveyor belt, a drive roller, a driven roller, and a conveyor belt drive motor, also overcomes the risk of card jamming present in fully enclosed card dispensing systems. Furthermore, card reader antenna mounting slots are provided on both sides of the support side plates, and a card reader antenna mounting plate is set between the two card reader antenna mounting slots. The card reader antenna mounting plate and the card reader antenna located on the card reader antenna mounting plate are located below the upper part of the conveyor belt, which also helps to increase the size of the card reader antenna and reduce the distance between the card reader antenna and the card, thereby improving card reading performance.

[0060] In one possible implementation, such as Figure 1 and Figure 3 As shown, the card reading and writing transmission mechanism is also equipped with a protective cover 13. One end of the protective cover 13 is fixed to the end of the outer frame 1 near the card slot panel 11, and the other end of the protective cover 13 is fixed to the card slot panel 11.

[0061] In this embodiment, by providing a protective cover 13 between the outer frame 1 and the card slot panel 11 of the card reading and writing transmission mechanism, external dust can be prevented from entering the interior of the card reading and writing transmission mechanism, thereby affecting the service life of the card reading and writing transmission mechanism.

[0062] For example, the protective cover 13 can be a accordion cover, a telescopic dust cover, a folding dust cover, or other structures that can provide protection and can retract between the outer frame 1 and the bayonet panel 11.

[0063] In one possible implementation, combined with Figure 1 and Figure 3 The card reading and writing transmission mechanism also includes: telescopic guide rail bracket 14, telescopic guide rail 15 and telescopic slider 16.

[0064] There are two telescopic guide rail brackets 14, and the two telescopic guide rail brackets 14 are respectively set on the upper sides of the outer frame 1, and are located at the end of the outer frame 1 away from the bayonet panel 11.

[0065] The number of telescopic guide rails 15 corresponds one-to-one with the number of telescopic guide rail brackets 14, and one end of the telescopic guide rail 15 is fixed to the telescopic guide rail bracket 14, while the other end of the telescopic guide rail 15 is fixed to the end of the outer frame 1 near the bayonet panel 11.

[0066] The number of telescopic sliders 16 corresponds one-to-one with the number of telescopic guide rails 15, and the telescopic sliders 16 are sleeved on the telescopic guide rails 15 and fixedly connected to the support side plate 2.

[0067] In this embodiment, two telescopic sliders 16 are fixedly connected to the support side plates 2 on both sides of the conveyor belt 4 respectively. At the same time, the two telescopic sliders 16 are correspondingly sleeved on the two telescopic guide rails 15. When the telescopic device drives the support side plates 2 on both sides of the conveyor belt 4, the entire card transmission device and the card slot panel 11 to extend and retract, they cooperate with the telescopic device to jointly drive the support side plates 2 on both sides of the conveyor belt 4 and the entire card transmission device to extend and retract, ensuring the safety and stability of the extension and retraction process.

[0068] In one possible implementation, such as Figure 2 and Figure 4 As shown, the card reading and writing transmission mechanism also includes a card position sensor 17.

[0069] Among them, the card position sensors 17 are respectively set at both ends and the top of the middle of the conveyor belt 4.

[0070] Combination Figure 2 and Figure 4As shown, in this embodiment, a card position sensor 17 can be set on a card position sensor base plate. Each card position sensor base plate can be fixed at a suitable position above the support side plates 2 on both sides of the conveyor belt 4, for example, the positions above the support side plates 2 on both sides of the conveyor belt 4 corresponding to the front and rear ends and the middle of the conveyor belt 4.

[0071] In this embodiment, by setting card position sensors 17 at both ends and above the middle of the conveyor belt 4, the position of the card 12 can be sensed in real time. When the card reading and writing antenna 9 fails to read or write the card 12, the external controller can use the sensed position to control the position of the card 12 on the card reading and writing antenna 9 to move forward or backward, so that the card reading and writing antenna 9 can re-read and write the card 12, thereby helping to improve the card reading success rate of the card reading and writing antenna 9 and improve the card reading performance.

[0072] In one possible implementation, such as Figure 4 As shown, each of the two supporting side plates 2 is provided with a conveyor belt tensioning groove 18 at the end away from the conveyor belt drive motor 3, and a tensioning bolt 19 is installed on the end face of each conveyor belt tensioning groove 18.

[0073] In this embodiment, considering that the conveyor belt 4 installed between the drive roller 5 and the driven roller 6 may have certain errors, a conveyor belt tensioning groove 18 is set at the front end of the support side plate 2 (that is, the end of the support side plate 2 on both sides of the conveyor belt 4 away from the conveyor belt drive motor 3), and a tensioning bolt 19 is installed on the end face of the conveyor belt tensioning groove 18, so that the tension of the conveyor belt 4 can be adjusted so that the conveyor belt 4 can meet the usage requirements.

[0074] In one possible implementation, the connection between the conveyor belt drive motor 3 and the drive shaft roller 5 may include a coupling, gears, or a conveyor belt.

[0075] For example, when connecting the conveyor belt drive motor 3 and the drive shaft roller 5 via a coupling, preparatory work can be performed before installation, such as:

[0076] Check the shaft diameter and coupling dimensions to ensure that the shaft diameter of the motor shaft and drive shaft roller matches the bore diameter of the coupling.

[0077] Remove dust, oil, and burrs from the shaft and coupling bore.

[0078] Use alignment tools (such as laser alignment instruments) to check the alignment of the motor shaft and drive shaft rollers to ensure that the deviation is within the allowable range.

[0079] After completing the pre-installation preparations, for sleeve-type couplings, the coupling can be fitted onto the motor shaft and drive shaft roller and secured with fastening screws.

[0080] For split couplings, the two halves can be installed on the motor shaft and the drive shaft roller respectively, and then connected by bolts.

[0081] When installing, please note: install one end first, then install the other end, and avoid forcibly striking the coupling.

[0082] After installation, check the alignment again and make adjustments if necessary. Tighten the bolts evenly with a torque wrench according to the coupling's instruction manual, avoiding overtightening or loosening.

[0083] For example, when connecting the conveyor belt drive motor 3 and the drive shaft roller 5 via gears, the preparation work before installation is similar to that for couplings, and will not be repeated here.

[0084] After completing the pre-installation preparations, the gear can be fitted onto the motor shaft and drive shaft roller, and secured with fastening screws. Alternatively, for split gears, the gear can be installed on the shaft first, and then connected with bolts.

[0085] Similarly, during installation, one end should be installed first, followed by the other end, to avoid forcibly striking the gears.

[0086] For example, when connecting the conveyor belt drive motor 3 and the drive shaft roller 5 via the conveyor belt, the appropriate type of conveyor belt can be selected first as needed.

[0087] Among them, flat belts are suitable for low-speed, light-load applications, and have a simple structure and low cost.

[0088] V-belts are suitable for medium-speed, medium-load applications, offering high transmission efficiency and high friction.

[0089] Synchronous belts are suitable for high-speed, high-precision applications, providing smooth transmission without slippage.

[0090] The selection can be made based on factors such as the required transmission ratio, torque, speed, installation space, and working environment (such as temperature and humidity).

[0091] Before installation, it is necessary to ensure that the shaft diameters of the motor shaft and the drive shaft roller match the bore diameters of the drive wheel and the driven wheel.

[0092] During installation, mount the drive wheel onto the motor shaft and secure it with set screws. Mount the driven wheel onto the drive shaft roller and secure it with set screws. Fit the conveyor belt onto the drive and driven wheels, adjust the center distance, and ensure the conveyor belt tension is appropriate.

[0093] In one possible implementation, such as Figure 1 As shown, the telescopic device includes a telescopic drive motor 7 and a telescopic component 8. The telescopic component 8 can be any one of a gear rack, a lead screw nut, or a pulley and timing belt.

[0094] For example, in combination Figure 1 As shown, when the telescopic part 8 is a gear rack, the telescopic drive motor 7 is connected to the gear, the gears mesh with each other, and the rack is connected to the bottom of the support side plate 2 on both sides of the conveyor belt 4 and the bayonet panel 11 respectively.

[0095] For example, when the telescopic part 8 is a lead screw and nut, the telescopic drive motor 7 is connected to the lead screw, the lead screw and the nut cooperate, and the nut is connected to the bottom of the support side plate 2 on both sides of the conveyor belt 4 and the bayonet panel 11 respectively.

[0096] For example, when the telescopic part 8 is a pulley and timing belt, the telescopic drive motor 7 is connected to the pulley, the timing belt is a toothed transmission belt, the pulley meshes with the timing belt, and the timing belt is connected to the bottom of the support side plate 2 on both sides of the conveyor belt 4 and the bayonet panel 11 respectively.

[0097] This utility model embodiment also provides a card issuing machine, which includes the card reading and writing transmission mechanism in any of the above embodiments, and has the same beneficial effects as the card reading and writing mechanism, which will not be described again here.

[0098] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
