Description

Technical Field

[0001] The present invention relates to the technical field of card issuing devices, and in particular to a card issuing machine. Background Art

[0002] At present, with the intelligent construction of expressways, automatic card issuing devices for expressway passing cards are gradually being promoted and used. The card issuing method of existing card issuing machines generally adopts a structural form that combines rubber roller transmission of cards with panel translation and extension for card delivery. There are some problems with this kind of structure: (1) The transmission component for card transmission needs to cooperate with multiple groups of rollers and floating wheel devices, resulting in a relatively complex structural design and making the installation of the whole machine more troublesome; (2) Using the method of rolling transmission of cards with rubber transmission wheels, there is a deficiency in poor use stability in abnormal environments such as low temperature or high temperature, and it is easy to have a situation where cards cannot be normally transmitted; (3) For the existing method of using panel translation and extension for card delivery, the panel and its driving structure are designed to be relatively large, occupying more chassis space, which is not conducive to the miniaturization design of card issuing devices; (4) The card taking opening of existing card issuing devices is generally an open design, and it is easy for external sundries such as sand and dust to enter, resulting in blockage, causing the transmission mechanism to fail and affecting the card issuing work; (5) Generally, only one card magazine for loading cards is fixedly provided, and the card loading capacity is small, and each card loading operation is inconvenient.

[0003] Therefore, it is necessary to improve the existing card issuing machine. Summary of the Invention

[0004] The purpose of the present invention is to provide a card issuing machine that can automatically push out and read and write information of cards, and clamp the cards by setting a rotatably mounted turning arm, and can flip open and deliver the cards after the reading and writing information is completed. The structure is compact and simple, the operation stability is good, and it is convenient for vehicle owners to take cards, which well solves the problems mentioned in the above background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A card issuing machine, comprising:

[0007] A frame, formed with a card delivery channel for pushing out cards;

[0008] At least one card magazine, located above the card delivery channel, the card magazine having a card storage cavity for storing and loading cards, and the card storage cavity having a card outlet communicating with the card delivery channel;

[0009] A turning arm, rotatably connected to the frame, and the turning arm is provided with a card clamping channel aligned and distributed towards the card delivery channel at one end far from the rotation axis, and the card clamping channel is used for carrying the cards pushed out by the card delivery channel;

[0010] A reading and writing device is installed on the frame and is located between the card feeding channel and the card clamping channel;

[0011] A turning arm rotation driving device is installed on the frame and is connected to the rotation shaft of the turning arm, and is used for driving the turning arm to rotate and send out the card after reading and writing is completed.

[0012] Furthermore, the turning arm is provided with a card clamping device located in the card clamping channel. The card clamping device includes at least a pair of clamping rollers respectively rotatably installed on both sides inside the card clamping channel. The card clamping channel is correspondingly provided with a U-shaped shaft groove for installing the rotation shaft of the clamping roller and a first torsion spring elastically abutted against the rotation shaft of the clamping roller. In this way, the card can be clamped and fixed on the turning arm more firmly and is not easily thrown off and fallen during the rotation of the turning arm; specifically, through the elastic clamping force provided by the first torsion spring, the clamping roller can automatically elastically clamp the card pushed into the card clamping channel, and the clamping roller can freely rotate with the insertion and extraction of the card, which not only has a certain ability to clamp the card, but also facilitates the vehicle owner to take out the card without much effort, and can improve the experience of the vehicle owner taking the card. By adjusting the distance between the card clamping channel and the card feeding channel, the card clamping device clamps a part of the card, so that the other part of the card exposes the card clamping channel on the turning arm, so that it is convenient for the vehicle owner to take the card from the turning arm when the turning arm is opened.

[0013] Furthermore, a waste card box is provided below the frame. The inside of the turning arm has a card recycling channel. One end of the card clamping channel away from the card feeding channel communicates with the upper part of the card recycling channel, and the lower part of the card recycling channel is distributed towards the opening of the waste card box. Sometimes, there will be a situation where writing information on the card fails (which can be regarded as a bad card). By setting the waste card box and rationally using the internal cavity structure of the turning arm as the card recycling channel, in this way, the next card can be used to push the card with failed writing information, so as to push it out of the card clamping channel and slide into the waste card box below through the card recycling channel, realizing the recycling of the card.

[0014] Further, a stopper is rotatably provided at the upper part of the card recycling channel near the card clamping channel. A second torsion spring is provided between the stopper and the turning arm. The stopper has a resisting inclined surface, and the frame is provided with a driving member for pressing against the resisting inclined surface to drive the stopper to rotate. When the turning arm is in the closed state, the driving member on the frame abuts against and contacts the resisting inclined surface on the stopper and can push the stopper to rotate upward by a certain angle, so as to create enough space at one end of the card clamping channel close to the card recycling channel, so that when facing a defective card, it can be pushed out and dropped into the card recycling channel; when the turning arm is in the open state, at this time, since the driving member is separated from the stopper, under the action of the second torsion spring, the stopper rotates downward and resets, thereby blocking one end of the card clamping channel close to the card recycling channel, and can prevent the vehicle owner from directly pushing the card into the card recycling channel and prevent accidental touch and inability to get the card.

[0015] Further, the frame is provided with a cartridge mounting seat, the cartridge mounting seat forms the card feeding channel, the cartridge mounting seat has a cartridge mounting groove with an open top communicating with the card feeding channel, and one end of the cartridge close to the card outlet is detachably connected to the cartridge mounting groove. By providing a detachable cartridge, the cards can be stacked in the cartridge in advance. Compared with the conventional integral fixed cartridge structure, there is no need to individually place the cards on site to replenish the cards, which has high convenience, can greatly improve the card replenishment efficiency, avoid the operator staying beside the lane for a long time, and greatly improve the safety of personnel.

[0016] Further, a limiting door is rotatably provided on a side wall of the cartridge mounting seat located on one side of the card feeding channel, and the limiting door is provided with a locking component. The cooperation of the locking component and the rotatably mounted limiting door can achieve the purpose of quickly installing and disassembling the cartridge without using tools, and can improve the installation and disassembly efficiency of the cartridge.

[0017] Further, the card issuing machine further includes an outer housing, and the outer housing has a turning arm outlet through which the turning arm can rotate and turn out. In this way, the turning arm can be rotated and closed after the card delivery action is completed. The structure is simple, which not only greatly reduces the overall space volume, but also makes the outer surface of the turning arm flush with the surface of the outer housing; since the turning arm is used to close the card taking opening, there is no opening exposed during the non-card feeding process, avoiding sundries from entering and blocking, which has more advantages for protecting the equipment, and makes the outer housing have a relatively flat appearance visual effect.

[0018] Further, the frame is provided with a card issuing machine control device, and the turning arm is provided with a card detection switch at the card clamping channel. The card detection switch, the reading and writing device, and the turning arm rotation driving device are respectively connected to the card issuing machine control device. The card detection switch is used to detect whether the card is pushed into the card clamping channel in place, so as to start the reading and writing device to read and write information on the card.

[0019] Further, the frame is provided with a first detector corresponding to the turning arm in the closed state and a second detector corresponding to the turning arm in the open state. The turning arm is provided with a first actuator that can trigger the first detector and the second detector respectively. The first detector and the second detector are respectively connected to the card issuing machine control device. In this way, the rotation angle of the turning arm can be accurately controlled, so as to control the operation of card delivery.

[0020] Further, the frame is provided with a card pushing device, and the card pushing device includes:

[0021] A slide rail, located below the card feeding channel and distributed along the card feeding channel;

[0022] A slider, slidably connected to the slide rail. The slider is provided with a card pushing member and a third torsion spring. The lower part of the card pushing member is rotatably connected to the slider. On both sides of the upper part of the card pushing member, there are respectively a top pushing surface and a reset guiding inclined surface. The third torsion spring is arranged between the slider and the card pushing member;

[0023] A slider driving device, arranged below the slide rail, for driving the slider to move along the slide rail.

[0024] Through the arranged slider driving device, the slider can be driven to move back and forth along the slide rail, so as to push out the cards in the card magazine by using the card pushing member on the slider.

[0025] Compared with the prior art, the present invention provides a card issuing machine, which has the following beneficial effects:

[0026] The present invention can automatically push out the cards in the card magazine and read and write information, and clamp the cards by setting a turning arm that is rotatably installed, and can flip open the cards after the reading and writing information is completed for delivery. Since the turning arm rotates and extends, the distance between the vehicle owner and the card issuing device is shortened, which is convenient for the vehicle owner to get the card, and has a good user experience; at the same time, by adopting the structural design of the turning arm, it can rotate and close after the card delivery action is completed, reducing the overall volume of the machine, with a compact and simple structure and good operation stability; and, during the card transmission movement process, the way of clamping with rolling rubber wheels is avoided, thus effectively solving the problems brought by the mechanism when used in extreme weather environments, such as the transmission mechanism fails due to low temperature icing, sand and dust fouling, etc.; the card pushing device of the present invention has a simple structure, is easier to manufacture, install and maintain, and the simple mechanism provides more guarantee for the operation stability of the equipment, and can significantly realize the miniaturized design of the equipment.

[0027] In addition, by setting at least one card magazine, the card loading capacity can be greatly increased, the number of card replenishments can be reduced, the maintenance workload of the staff can be reduced, the operator can be prevented from staying beside the lane for a long time, and the safety of the personnel is greatly improved.

[0048] The technical solution of the present invention will be clearly and completely described below through detailed embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 18 , this embodiment provides a card issuing machine, which includes a frame 1, a turning arm 3, a reading and writing device 4, and a turning arm rotation driving device 5. Among them, the frame 1 is formed with a card feeding channel 11 for pushing out the card 9. At least one card magazine 2 is provided above the card feeding channel 11. The card magazine 2 has a card storage cavity 24 for storing and loading the card 9, and the card storage cavity 24 has a card outlet 211 communicating with the card feeding channel 11. The turning arm 3 is rotatably connected to the frame 1. At the end of the turning arm 3 away from the rotation axis 31, there is a card clamping channel 32 arranged in alignment with the card feeding channel 11. The card clamping channel 32 is used to carry the card 9 pushed out by the card feeding channel 11. The reading and writing device 4 is installed on the frame 1 and is located between the card feeding channel 11 and the card clamping channel 32. The turning arm rotation driving device 5 is installed on the frame 1 and is connected to the rotation axis 31 of the turning arm 3, and is used to drive the turning arm 3 to rotate and send out the card 9 after reading and writing. The card issuing machine can automatically push out and read and write information on the card, and use the rotatably installed turning arm to clamp the card, and can flip open and deliver the card after reading and writing information, which is convenient for the car owner to take the card, and has a compact and simple structure and good operation stability.

[0050] In this embodiment, the frame 1 is provided with a card issuing machine control device 8. The turning arm 3 is provided with a card detection switch 81 located at the card clamping channel 32. The card detection switch 81, the reading and writing device 4, and the turning arm rotation driving device 5 are respectively connected to the card issuing machine control device 8. By setting the card detection switch, it can be used to detect whether the card is pushed into the card clamping channel in place, so as to start the reading and writing device to read and write information on the card.

[0051] In some specific embodiments, the reading and writing device 4 includes an antenna board with the function of reading and writing cards. The turning arm rotation driving device 5 includes a driving motor with a reduction gear set.

[0052] As an improved embodiment, refer to Figure 3, in order to better control the rotation of the turning arm, the frame 1 is provided with a first detection member 82 corresponding to the turning arm in the closed state and a second detection member 83 corresponding to the turning arm in the open state. The turning arm 3 is provided with a first actuating member 35 that can trigger the first detection member and the second detection member respectively. The first detection member 82 and the second detection member 83 are respectively connected to the card issuing machine control device 8. Among them, the first detection member corresponds to the position of the turning arm when it is in the closed state, and the second detection member corresponds to the position of the turning arm when it is in the open state. In this way, the rotation angle of the turning arm can be accurately controlled, so as to control the operation of card delivery.

[0053] In this embodiment, referring to Figures 1 to 18 , the frame 1 is provided with a card pushing device 16. The card pushing device 16 includes a slide rail 161, a slider 162 and a slider driving device 165. Specifically, the slide rail 161 is located below the card feeding channel 11 and is distributed along the card feeding channel 11. The slider 162 is slidably connected to the slide rail 161. The slider 162 is provided with a card pushing member 163 and a third torsion spring 164. The lower part of the card pushing member 163 is rotatably connected to the slider 162. The upper part of the card pushing member 163 is provided with a pushing surface 1631 and a reset guiding inclined surface 1632 on both sides respectively. The third torsion spring 164 is arranged between the slider 162 and the card pushing member 163; under the action of the third torsion spring, the pushing surface of the card pushing member remains in a vertical plane distribution so as to smoothly push out the card, while the reset guiding inclined surface is distributed at a certain angle with the pushing surface so that when the card pushing member retreats and resets, it can flip a certain angle to cross the card and thus smoothly return to the initial position. The slider driving device 165 is arranged below the slide rail 161 and is used to drive the slider to move along the slide rail. Through the arranged slider driving device, the slider can be driven to move back and forth along the slide rail, so as to push out the card in the card magazine by using the card pushing member on the slider. In some specific embodiments, the slider driving device 165 includes a transmission belt 1651 and a transmission belt driving motor 1652 that can drive the transmission belt to rotate forward and backward. By connecting the slider to the transmission belt, the slider can be driven to move back and forth to realize pushing out the card.

[0054] As an improved embodiment, referring to Figure 3 , the frame 1 is provided with a third detection member 84 corresponding to the card pushing member at the card pushing origin position and a fourth detection member 85 corresponding to the card pushing member at the card pushing in place position. The slider 162 is provided with a second actuating member 1621 that can trigger the third detection member and the fourth detection member respectively. The third detection member 84 and the fourth detection member 85 are respectively connected to the card issuing machine control device 8. Among them, the third detection member corresponds to the initial position of the card pushing member, and the fourth detection member corresponds to the card pushing in place position. In this way, the moving distance of the card pushing member can be accurately controlled, so as to control the operations of card pushing and card pushing member resetting.

[0055] Preferably, the four detection components can be photoelectric switches, and the two actuating components can be baffles. In some other embodiments, the four detection components can also be microswitches, and the two actuating components are paddles corresponding to the microswitches that can be pressed.

[0056] In some embodiments, referring to Figure 16 and Figure 17 , the card dispenser further includes an outer housing 7. The outer housing 7 has a flap extension opening 71 through which the flap 3 can rotate and extend out. This flap extension opening can be used as a card-taking opening. In this way, after the card delivery action is completed, the flap can be rotated and closed. The structure is simple, which not only greatly reduces the overall space volume of the machine, but also makes the outer surface of the flap flush with the surface of the outer housing, covering the flap extension opening. Since the card-taking opening is closed by the flap, there is no opening exposed during the non-card-delivery process, avoiding debris from entering and blocking, which has more advantages in protecting the equipment and makes the outer housing have a relatively flat visual appearance.

[0057] In some embodiments, in order to be able to fix the delivered card, the flap 3 is provided with a card clamping device 33 located in the card clamping channel 32. Specifically, referring to Figures 1 to 6 and referring to Figures 16 to 18 , the card clamping device 33 includes at least a pair of clamping rollers 331 that are respectively rotatably installed on both sides inside the card clamping channel 32. The card clamping channel 32 is correspondingly provided with a U-shaped shaft groove 321 for installing the rotating shaft of the clamping roller and a first torsion spring 322 that elastically abuts against the rotating shaft of the clamping roller. In this way, the card can be relatively firmly clamped and fixed on the flap and is not easily thrown off and detached during the rotation of the flap. Specifically, through the elastic clamping force provided by the first torsion spring, the clamping rollers can automatically elastically clamp the card pushed into the card clamping channel, and the clamping rollers can freely rotate with the insertion and removal of the card. It not only has a certain ability to clamp the card but also facilitates the vehicle owner to take out the card without much effort, which can improve the vehicle owner's card-taking experience. By adjusting the distance between the card clamping channel and the card delivery channel, the card clamping device clamps a part of the card, so that the other part of the card exposes from the card clamping channel on the flap. In this way, when the flap is opened, it is convenient for the vehicle owner to take the card from the flap. As an example, there are four pairs of clamping rollers, and they are symmetrically distributed at the card clamping channel. More specifically, the clamping rollers are made of metal rollers and are rotatably installed with metal bearings to avoid the problems existing in the use of conventional rubber wheels in extreme environments.

[0058] In some embodiments, referring to Figures 1 to 18, in order to be able to recycle the cards that fail to be written, a waste card box 6 is provided below the rack 1. The inside of the turning arm 3 has a card recycling channel 34. One end of the card clamping channel 32 away from the card feeding channel 11 communicates with the upper part of the card recycling channel 34, and the lower part of the card recycling channel 34 is distributed towards the opening of the waste card box 6. Sometimes, there will be a situation where writing information on the card fails (which can be regarded as a bad card). By setting up a waste card box and rationally using the internal cavity structure of the turning arm as a card recycling channel, in this way, the next card can be used to push the card that fails to write information, so as to push it out of the card clamping channel and slide down through the card recycling channel into the waste card box below, realizing the recycling of the card.

[0059] As an improved implementation method, referring to Figure 4 , Figure 5 , Figures 16 to 18 , in order to prevent the card from being directly pushed into the card recycling channel after the turning arm is opened, a stopper 341 is rotatably provided at the upper part of the card recycling channel 34 near the card clamping channel. A second torsion spring 342 is provided between the stopper 341 and the turning arm 3. The stopper 341 has an abutting inclined surface 3411, and the rack 1 is provided with a driving member 12 for pressing against the abutting inclined surface to drive the stopper to rotate. When the turning arm is in the closed state, the driving member on the rack abuts against and contacts the abutting inclined surface on the stopper and can push the stopper to rotate upward by a certain angle, so that enough space is vacated at one end of the card clamping channel near the card recycling channel, so that when facing a bad card, it can be pushed out and fall into the card recycling channel; when the turning arm is in the open state, since the driving member is separated from the stopper, under the action of the second torsion spring, the stopper rotates downward to reset, blocking the end of the card clamping channel near the card recycling channel, and can prevent the vehicle owner from directly pushing the card into the card recycling channel, preventing accidental touch and inability to get the card.

[0060] In some implementation methods, referring to Figures 1 to 18 , the rack 1 is provided with a card magazine mounting seat 13 for assembling the card magazine 2. The card magazine mounting seat 13 forms the above-mentioned card feeding channel 11. The card magazine mounting seat 13 has a card magazine mounting groove 131 with an open top communicating with the card feeding channel. One end of the card magazine 2 near the card outlet 211 is detachably connected to the card magazine mounting groove 131. By setting a detachable card magazine, the cards can be stacked in the card magazine in advance. Compared with the conventional integral fixed card magazine structure, there is no need to put the cards into the card one by one on site to replenish the card, which has high convenience, can greatly improve the card replenishment efficiency, avoid the operator staying beside the lane for a long time, and greatly improve the safety of personnel. Specifically, a limit door 14 is rotatably provided on the side wall of the card magazine mounting seat 13 located on one side of the card feeding channel, and the limit door 14 is provided with a lock assembly 15 for locking. By using the lock assembly and the rotatably mounted limit door in cooperation, the purpose of quickly installing and disassembling the card magazine can be achieved without using additional tools, and the installation and disassembly efficiency of the card magazine can be improved.

[0061] In some specific embodiments, referring to Figures 1 to 18 , the cartridge 2 includes a base 21, a top seat 22 located above the base, and a cartridge body 23 disposed between the base and the top seat. An above-mentioned card storage cavity 24 is formed inside the cartridge 2 along the height direction. An insertion slot communicating with the card storage cavity is provided at the upper part of the top seat 22. The top seat 22 is provided with a top cover 25 for covering the insertion slot. At both ends of the lower part of the base 21, the above-mentioned card outlet slots 211 are respectively provided. The base 21 is provided with a baffle assembly 26 located at the card outlet slot. The base 21 is provided with a horizontally extending chute 212 and a vertically extending chute 213 that are vertically communicated, and an insertion hole 214 communicating with the horizontally extending chute. The baffle assembly 26 includes a limit baffle 261 slidably installed in the vertically extending chute and a limit push plate 262 slidably installed in the horizontally extending chute. Opposite collision inclined surfaces 263 are respectively provided on the upper part of the limit baffle 261 and the lower part of the limit push plate 262. A first return spring 264 for driving the limit baffle to move towards the limit push plate is provided between the vertically extending chute and the limit baffle. A second return spring 265 for driving the limit push plate to move towards the insertion hole is provided between the horizontally extending chute and the limit push plate. A protective cover 215 for covering the limit baffle and the limit push plate is provided on the outer wall of the base. A bottom plate 17 for mounting with the frame is provided below the cartridge mounting seat. A card feeding channel as described above is formed between the cartridge mounting seat and the bottom plate. The bottom plate is provided with guiding through slots 171 distributed along the card feeding channel, so that the card pushing member on the slider can extend out to push the card. The cartridge mounting slot has an open top and an open side. The lower part of the cartridge mounting slot communicates with the card feeding channel. The cartridge 2 is assembled and fixed to the cartridge mounting slot 131 by means of lateral insertion. A ejector rod 132 for plugging and connecting with the cartridge is provided on the inner wall of the cartridge mounting slot 131 on the side away from the open side. The ejector rod is distributed towards the open side and is aligned with the insertion hole on the base. The ejector rod is used to push against the baffle assembly.

[0062] By providing an open U-shaped opening structure on the cartridge mounting seat and cooperating with the locking of the limit door, the cartridge can be quickly fixed, improving the efficiency of replacing the cartridge. In addition, by providing an ejector rod for plugging with the cartridge, on the one hand, the ejector rod can play a good positioning role for the cartridge, and on the other hand, the ejector rod can also push and move the baffle assembly on the cartridge, thereby opening the card outlet slot, so that the card can be pushed out from the card storage cavity and slide along the card feeding channel, performing the function of turning on the card limit switch.

[0072] The card issuing process and card recycling process of the present invention are as follows:

[0073] When in use, as Figure 8 shown, open the lock component, flip open the side door component 27 and the top cover 25, lift the weight component 28 upward to the card insertion opening and flip it to one side, stack the cards 9 in sequence into the card storage cavity 24; then, as Figure 12 shown, flip the weight component 28, close the side door component 27 and press down the weight component 28, and use the lock component again to lock the top cover 25 and the side door component 27. The weight component 28 presses the cards 9 tightly under the action of the spring buckle 282 to complete card loading.

[0074] During the supplementary card operation, referring to Figure 14 and Figure 15 , push the card magazine 2 containing the cards 9 into the card magazine installation slot 131 on the card magazine mounting base 13. After the card magazine 2 is installed in place, the ejector rod 132 will automatically open the card outlet 211 at the bottom of the card magazine 2 to ensure that the bottommost card in the card storage cavity of the card magazine can be ejected.

[0075] Referring to Figure 4 and Figure 16 , when it is detected that a vehicle is approaching and a card needs to be issued, under the linkage action of the card pushing device 16, the card pusher 163 moves forward along the slide rail 161 from the initial position to push the card until the foremost card is pushed into the clamping channel 32 of the turning arm 3 and is automatically clamped by the card clamping device 33. Among them, during the card pushing process, there are three situations: (1) When there are cards in both card magazines, the card in the rearmost card magazine is pushed by the card pusher and pushes the card in the front card magazine into the clamping channel on the turning arm; (2) When there are cards in the rearmost card magazine and no cards in the front card magazine, the card pusher directly pushes the card in the rearmost card magazine into the clamping channel of the turning arm; (3) When there are no cards in the rearmost card magazine and there are cards in the front card magazine, the card pusher first moves an empty stroke and, after hitting the card in the front card magazine, then pushes the card into the clamping channel of the turning arm.

[0076] After the card is pushed out in place, the card 9 will trigger the card detection switch 81, thereby starting the reading and writing device 4 to write information on the card. Referring to Figure 3 and Figure 17 , after the card information writing is completed, the turning arm 3 rotates outward and opens, delivering the card to the vehicle owner to pick up the card, completing card issuance.

[0077] Referring to Figure 18When the information writing to the card by the reading and writing device fails, the turning arm will not rotate and open. The card pushing device 16 will continue to push out the next card, and use the thrust of the next card to push the card with writing failure on the turning arm 3 away from the card clamping channel 32, and slide down along the card recycling channel 34 into the waste card box 6; afterwards, the card with successful re-reading and writing will be rotated and opened outward by the turning arm 3 to complete the card issuing action.

[0078] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
