Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and in particular to a self-service card printing device. Background Technology

[0002] Using cards to carry information and images is a common method, such as business cards and children's entertainment cards. Existing card printers typically include a card tray, a card feeding device, a card position detection device, and a printhead assembly. Blank cards are fed from the card tray to the printhead assembly by the card feeding device, and the card position detection device locates and detects the card. After the blank card is in place, the printhead assembly prints the pre-stored information or image onto the card. However, existing card printers can only print on one side. To print on both sides, the card must be repositioned after one side is printed and then fed to the printhead assembly to print the other side. This operation is cumbersome, lacks a high level of automation, and is particularly unsuitable for self-service card vending machines. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a self-service card printing device with the advantages of being able to print on both sides and improving the intelligence of printing.

[0004] The objective of this invention is achieved through the following technical solution: According to an embodiment of this disclosure, a self-service card printing device is provided, comprising: The frame has a card compartment on the first side and a card dispensing port on the second side. The card compartment is used to store stacks of blank cards, and the card dispensing side of the card compartment has a card inlet that allows only one card to pass through at a time. A rotary platform is rotatably mounted on the frame. The rotary platform is provided with a transfer conveying mechanism for clamping and feeding cards. The frame is provided with a rotary drive mechanism for driving the rotary platform to reciprocate and rotate. The frame is also provided with a card feeding drive mechanism located at the bottom of the card compartment for driving the cards to move to the rotary platform. A printing platform mounted on a frame and connected to the rotary platform, the printing platform being equipped with a card feeding drive mechanism for driving cards to move to the card dispensing slot or return to the rotary platform; and, A printing device mounted on the rack and located above the printing platform for printing information on blank cards.

[0005] To achieve the above technical solution, during card printing, the user inputs the designed card information into the control system of the printing equipment. Then, the card feed drive mechanism drives the card tray to feed the blank card (located at the bottom) into the rotary platform. The rotary platform receives the card, which is then carried forward by a transfer conveyor mechanism to the printing platform. The card is then further driven by a card delivery drive mechanism. During this movement, the printing device prints the corresponding information on the top surface of the card. If only one side needs to be printed, the card delivery drive mechanism removes the card from the output slot, completing the printing process. If a second side needs to be printed... The card is driven to move in the reverse direction by the card feeding mechanism, returning the card to the rotating platform. The transfer conveyor then picks up the card and moves it to the predetermined position. The rotating drive mechanism then drives the rotating platform to rotate approximately 180°, completing the card reversal process. The transfer conveyor then drives the card to move to the printing platform again, and the above process can be repeated to print on the second side of the card. This achieves automatic reversal and double-sided printing, improves printing intelligence, simplifies the overall control process, and enhances the overall integration of the device, making it more suitable for self-service printing operations in self-service card vending machines.

[0006] In some exemplary embodiments, a card inlet gate is slidably mounted vertically on the card dispensing side of the card compartment on the frame. The card inlet gate is elastically connected to the frame so that its bottom forms the card inlet opening between the bottom and the surface of the frame. An adjusting slider is also slidably disposed on the frame above the card inlet gate. The bottom of the adjusting slider is provided with an inclined adjusting slope, which is used to abut against the card inlet gate to adjust the height of the card inlet gate.

[0007] To achieve the above technical solution, since the card inlet gate is elastically connected to the frame, the card inlet gate has an upward sliding tendency. By sliding the adjusting slider, different positions of the adjusting slope are made to abut against the card inlet gate, so that the card inlet gate can be positioned at different heights, thereby adjusting the size of the card inlet to accommodate cards of different thicknesses.

[0008] In some exemplary embodiments, a sliding seat is provided on the frame above the card inlet gate, the adjusting slider is slidably mounted on the sliding seat in the horizontal direction, and an adjusting roller is rotatably connected to the top of the card inlet gate, the adjusting roller abutting against the adjusting inclined surface.

[0009] To achieve the above technical solution, the gate can be adjusted to different heights by adjusting the inclined plane pressing the adjusting roller.

[0010] In some exemplary embodiments, the card feeding drive mechanism includes: a card feeding roller rotatably mounted on the frame, and a card feeding drive component for driving the card feeding roller to rotate, wherein the card feeding roller is in contact with a blank card located at the bottom of the card compartment.

[0011] To achieve the above technical solution, the card feeding roller is driven to rotate by the card feeding drive component. The friction between the card feeding roller and the card can then transfer the blank card at the bottom from the card feeding port to the rotary platform.

[0012] In some exemplary embodiments, the frame has a card inlet channel at the bottom of the card compartment for inserting only a single blank card, the rotary drive mechanism can drive the rotary platform to rotate to be in contact with the card inlet channel, and the frame carries a single card feeding mechanism that is in contact with the card inlet channel.

[0013] To achieve the above technical solution, the card compartment can be used to store regular cards for printing. When special cards are needed for single-sheet printing, the card can be placed in the card inlet channel. At this time, the rotary drive mechanism drives the rotary platform to rotate to be in contact with the card inlet channel. Then, the single-sheet card feeding mechanism transfers the card to the rotary platform, and subsequent transfer and printing operations can be performed.

[0014] In some exemplary embodiments, the transfer and conveying mechanism includes: A transfer drive roller is rotatably mounted on the rotary platform, and the transfer drive roller is flush with the surface of the rotary platform; A transfer frame hinged to the rotary platform, a transfer pressure roller mounted on the transfer frame above the transfer drive roller, and the transfer frame being elastically connected to the rotary platform so that the transfer pressure roller presses against the transfer drive roller; and, A transfer drive component supported on the rotary platform for driving the transfer drive roller to rotate.

[0015] To achieve the above technical solution, the transfer pressure roller is elastically pressed against the transfer drive roller by the transfer movable frame, which can elastically clamp the card. Then, the transfer drive roller is driven to rotate by the transfer drive component, which can drive the card to be transferred.

[0016] In some exemplary embodiments, the rotary platform is further provided with a transfer position detection sensor for detecting the card position, and the transfer conveying mechanism controls the stepping distance based on the position information detected by the transfer position detection sensor.

[0017] To achieve the above technical solution, the card's position is detected by a transfer position detection sensor, enabling the card to be moved to the precise displacement of the rotary platform for flipping operation, and the card's movement distance can be accurately controlled during the printing process.

[0018] In some exemplary embodiments, the card feeding drive mechanism includes: A printing drive roller is rotatably mounted on the printing platform, and the printing drive roller is flush with the surface of the printing platform; A movable printing frame hinged to the printing platform, wherein a printing pressure roller is provided on the movable printing frame above the printing drive roller, and the movable printing frame is elastically connected to the printing turntable so that the printing pressure roller presses against the printing drive roller; and, A printing drive unit mounted on the printing platform for driving the printing drive roller to rotate.

[0019] To achieve the above technical solution, the printing pressure roller is elastically pressed against the printing drive roller by the printing movable frame, which can elastically clamp the card. Then, the printing drive roller is driven to rotate by the printing drive component, which can drive the card to be transferred.

[0020] In some exemplary embodiments, the card insertion channel is further provided with a card insertion detection sensor. When the card insertion detection sensor detects the insertion of a card, the rotary drive mechanism drives the rotary platform to rotate to be in contact with the card insertion channel, and the single card feeding mechanism drives the card to move and be fed into the rotary platform.

[0021] The above technical solutions will further improve the intelligence of printing control.

[0022] In some exemplary embodiments, the frame is further provided with an inclined card dispensing channel below the card inlet channel, and the rotary drive mechanism can drive the rotary platform to rotate to be in contact with the card dispensing channel.

[0023] By implementing the above technical solution, the printed cards can be set to be sent out from the card outlet or card outlet channel as needed, thereby increasing the diversity of card issuance.

[0024] In summary, compared with the prior art, the present invention has the following beneficial effects: This invention provides a self-service card printing device, comprising: a frame, a card compartment on a first side and a card dispensing port on a second side, the card compartment for storing stacked blank cards, and a card inlet on the dispensing side of the card compartment for only one card to pass through at a time; a rotating platform rotatably mounted on the frame, the rotating platform having a transfer conveying mechanism for clamping and feeding cards, a rotating drive mechanism on the frame for driving the rotating platform to reciprocate, and a card feeding drive mechanism located at the bottom of the card compartment on the frame for moving cards to the rotating platform; a printing platform mounted on the frame and connected to the rotating platform, the printing platform having a card feeding drive mechanism for driving cards to move to the card dispensing port or return to the rotating platform; and a printing device mounted on the frame and located above the printing platform for printing information on blank cards. During card printing, the user inputs the designed card information into the printing equipment's control system. Then, the card feed drive mechanism moves the card tray, containing the blank card at the bottom, from the card inlet into the rotary platform. The rotary platform receives the card, which is then carried forward by a transfer conveyor mechanism to the printing platform. The card is then further moved by the card delivery drive mechanism. During this movement, the printing device prints the corresponding information on the top surface of the card. If only one side needs to be printed, the card delivery drive mechanism removes the card from the card outlet, completing the printing process. If a second side needs to be printed, the card is then... The card drive mechanism drives the card to move in the reverse direction, returning the card to the rotating platform. The transfer conveyor then picks up the card and moves it to the predetermined position. The rotating drive mechanism then drives the rotating platform to rotate approximately 180°, completing the card reversal process. The transfer conveyor then drives the card back to the printing platform, and the above process is repeated to print on the second side of the card. This achieves automatic reversal and double-sided printing, improving printing intelligence and simplifying the overall control process. The device has a high degree of integration and is more suitable for self-service printing operations in self-service card vending machines. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8As shown, this embodiment of the invention provides a self-service card printing device, including: a frame 10, a card compartment 11 on a first side and a card outlet 12 on a second side, the card compartment 11 for storing stacked blank cards, and a card inlet 13 on the card outlet side of the card compartment 11 for only one card to pass through; a rotating platform 20 rotatably mounted on the frame 10, the rotating platform 20 having a transfer conveyor 21 for clamping and feeding cards, and the frame 10 having a mechanism for driving the rotating platform 20 to reciprocate. The frame 10 includes a rotary drive mechanism 22 for flipping motion, and a card feeding drive mechanism 14 located at the bottom of the card compartment 11 for moving cards to the rotary platform 20; a printing platform 30 supported on the frame 10 and connected to the rotary platform 20, and a card feeding drive mechanism 40 on the printing platform 30 for moving cards to the card outlet 12 or returning them to the rotary platform 20; and a printing device 50 supported on the frame 10 and located above the printing platform 30 for printing information on blank cards.

[0036] Specifically, the frame 10 is hinged with an openable cover. Under normal circumstances, the cover is closed to seal and protect the printing device 50, the rotating platform 20 and other components. The bottom of the card compartment 11 is usually slightly inclined inward, and a set of rollers is provided at the bottom of the card compartment 11 to allow the card to enter the card slot 13.

[0037] A card inlet gate 15 is slidably mounted vertically on the card dispensing side of the card compartment 11 on the frame 10. The card inlet gate 15 is elastically connected to the frame 10 so that its bottom forms a card inlet 13 between the bottom and the surface of the frame 10. An adjusting slider 16 is also slidably mounted on the frame 10 above the card inlet gate 15. The bottom of the adjusting slider 16 is provided with an inclined adjusting slope 161, which is used to abut against the card inlet gate 15 to adjust the height of the card inlet gate 15. A spring is usually provided between the card inlet gate 15 and the frame 10. The card inlet gate is L-shaped, and its main body is slidably inserted into the frame 10. A groove is provided on the frame 10, and the spring is fixedly embedded in the groove. The upper end of the spring is connected to the bending part of the card inlet gate, thereby realizing the elastic connection of the card inlet gate.

[0038] Since the card inlet gate is elastically connected to the frame 10, the card inlet gate has a tendency to slide upward. By sliding the adjusting slider 16, the adjusting ramp 161 is made to abut against the card inlet gate at different positions, so that the card inlet gate can be positioned at different heights, thereby adjusting the size of the card inlet 13 to accommodate cards of different thicknesses.

[0039] In this embodiment, a sliding seat 17 is provided on the frame 10 above the card entry gate 15. The adjusting slider 16 is slidably mounted on the sliding seat 17 in the horizontal direction. There needs to be a certain friction between the adjusting slider 16 and the sliding seat 17 so that the adjusting slider 16 will not slide arbitrarily after the sliding adjustment is completed. An adjusting roller 151 is rotatably connected to the top of the card entry gate 15. The adjusting roller 151 abuts against the adjusting inclined surface 161. Usually, an installation port is opened in the bending part of the card entry gate. The adjusting roller 151 is rotatably connected in the installation port through a rotating shaft. By pressing the adjusting roller 151 against the adjusting inclined surface 161, the card entry gate can be adjusted to different heights.

[0040] The card feeding drive mechanism 14 includes: a card feeding roller 141 rotatably mounted on the frame 10, and a card feeding drive component 142 for driving the card feeding roller 141 to rotate. The card feeding roller 141 is in contact with the blank card located at the bottom in the card compartment 11. The card feeding drive component 142 can be a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. In this embodiment, a belt drive mechanism is preferred, and the rotation is driven by a servo motor. By driving the card feeding roller 141 to rotate through the card feeding drive component 142, the blank card located at the bottom can be transferred from the card inlet 13 to the rotary platform 20 by the friction between the card feeding roller 141 and the card.

[0041] To facilitate the detection of whether there are still cards in the card compartment 11, a card shortage detection sensor 111 is also provided at the bottom of the card compartment 11. The card shortage detection sensor 111 adopts an elastic detection switch. When there are cards in the card compartment 11, the elastic detection switch will be pressed down under the action of the weight of the cards. When the cards in the card compartment 11 are used up, the elastic detection switch will spring up, thereby generating a card shortage signal.

[0042] Furthermore, a card feeding channel 18 for inserting only a single blank card is provided at the bottom of the card compartment 11 on the frame 10. The rotary drive mechanism 22 can drive the rotary platform 20 to rotate to be in contact with the card feeding channel 18. The frame 10 carries a single card feeding mechanism 181 that is in contact with the card feeding channel 18. The single card feeding mechanism 181 includes: two sets of oppositely arranged extrusion rollers, and an extrusion drive component for driving at least one of the extrusion rollers to rotate. The extrusion drive component can also adopt a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. In this embodiment, a belt drive mechanism is preferably used, which is driven to rotate by a servo motor. After the card is inserted between the two extrusion rollers, it can be driven to move forward. The card compartment 11 can be used to store regular cards for printing. When special cards are needed for single-sheet printing, the card can be placed in the card inlet channel 18. At this time, the rotary drive mechanism 22 drives the rotary platform 20 to rotate to be in contact with the card inlet channel 18. Then, the single-sheet card feeding mechanism 181 transfers the card to the rotary platform 20, and the subsequent transfer and printing operation can be performed.

[0043] Typically, a card insertion detection sensor 182 is also provided on the card insertion channel 18. When the card insertion detection sensor 182 detects a card insertion, the rotary drive mechanism 22 drives the rotary platform 20 to rotate to be in contact with the card insertion channel 18, and the single card feeding mechanism 181 drives the card to move and feed it into the rotary platform 20. The card insertion detection sensor 182 can be, for example, a photoelectric sensor, thereby further improving the intelligence of printing control. It can usually be configured such that, under normal circumstances, the card compartment 11 supplies the card, and when the card insertion detection sensor 182 detects a card insertion, the card insertion channel 18 supplies the card first. Of course, in some embodiments, the priority of card feeding can also be selected and configured by the control system.

[0044] The central part of the rotary platform 20 is rotatably connected to the frame 10 via a rotating shaft. The rotary platform 20 can rotate at least 180° in either the forward or reverse direction. The rotary drive mechanism 22 can also be a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. In this embodiment, a belt drive mechanism is preferred, and the rotation is driven by a servo motor.

[0045] The transfer conveying mechanism 21 includes: a transfer drive roller 211 rotatably mounted on the rotary platform 20, the transfer drive roller 211 being flush with the surface of the rotary platform 20; a transfer movable frame 212 hinged to the rotary platform 20, a transfer pressure roller 213 being provided on the transfer movable frame 212 above the transfer drive roller 211, and the transfer movable frame 212 being elastically connected to the rotary platform 20 so that the transfer pressure roller 213 presses against the transfer drive roller 211; and a transfer drive member 214 supported on the rotary platform 20 for driving the transfer drive roller 211 to rotate.

[0046] A hinged seat is provided on the rotary platform 20, and the transfer movable frame 212 is hinged to the hinged seat. The transfer pressure roller 213 is rotatably connected to the middle of the front side of the transfer movable frame 212. A limit plate is fixed on the rotary platform 20, spanning above the transfer movable frame 212. A spring is provided between the limit plate and the transfer movable frame 212 to make the transfer pressure roller 213 elastically press against the transfer drive roller 211, thereby stabilizing the extrusion and clamping of cards. The transfer drive component 214 can also adopt a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. In this embodiment, a belt drive mechanism is preferred, and the rotation is driven by a servo motor. By having the transfer movable frame 212 drive the transfer pressure roller 213 to elastically press against the transfer drive roller 211, the card can be elastically clamped. Then, by having the transfer drive component 214 drive the transfer drive roller 211 to rotate, the card can be transferred.

[0047] Furthermore, the rotary platform 20 is also equipped with a transfer position detection sensor 23 for detecting the card position. The transfer conveying mechanism 21 controls the step distance based on the position information detected by the transfer position detection sensor 23. The transfer position detection sensor 23 can be a photoelectric sensor. When the card passes through the transfer position detection sensor 23 and a detection signal is generated, when the card moves forward, this signal is the card position signal, which means that the card is completely on the rotary platform 20. It is used as a positioning signal to effectively control the step distance of the subsequent movement to the printing platform 30. When the card moves in the opposite direction, this signal is the card entry signal, which means that the card has just been transferred from the printing platform 30 to the rotary platform 20. It can be used as a positioning signal to control the distance the card continues to move until it is completely on the rotary platform 20.

[0048] The card's position is detected by the transfer position detection sensor 23, which enables the card to be moved to the accurate displacement of the rotary platform 20 for flipping operation, and can accurately control the card's movement distance during the printing process.

[0049] The card feeding drive mechanism 40 includes: a printing drive roller 41 rotatably mounted on the printing platform 30, the printing drive roller 41 being flush with the surface of the printing platform 30; a printing movable frame 42 hinged to the printing platform 30, a printing pressure roller 43 being provided on the printing movable frame 42 above the printing drive roller 41, and the printing movable frame 42 being elastically connected to the printing turntable so that the printing pressure roller 43 presses against the printing drive roller 41; and a printing drive component 44 supported on the printing platform 30 for driving the printing drive roller 41 to rotate.

[0050] A hinged seat is provided on the printing platform 30, and the printing movable frame 42 is hinged to the hinged seat. The printing pressure roller 43 is rotatably connected to the middle of the front side of the printing movable frame 42. A limit plate is fixed on the printing platform 30, spanning above the printing movable frame 42. A spring is provided between the limit plate and the printing movable frame 42 to make the printing pressure roller 43 elastically press against the printing drive roller 41, thereby stabilizing the extrusion and clamping of the card. The printing drive component 44 can also adopt a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. In this embodiment, a belt drive mechanism is preferred, and the rotation is driven by a servo motor. By driving the printing pressure roller 43 to elastically press against the printing drive roller 41 through the printing movable frame 42, the card can be elastically clamped. Then, by driving the printing drive roller 41 to rotate through the printing drive component 44, the card can be moved.

[0051] Preferably, in this embodiment, two sets of card feeding drive mechanisms 40 are symmetrically arranged to meet the needs of printing cards over a longer distance. The printing pressure rollers 43 in the two sets of card feeding drive mechanisms 40 are linked by a belt mechanism. The power output end of the printing drive component 44 is located between the two printing drive rollers 41. The two printing drive rollers 41 are connected by synchronous belt drive, so that when the printing drive component 44 works, it can drive the two printing drive rollers 41 to rotate simultaneously and move the card.

[0052] Furthermore, an inclined card dispensing channel 19 is provided on the frame 10 below the card inlet channel 18. The rotary drive mechanism 22 can drive the rotary platform 20 to rotate to be in contact with the card dispensing channel 19. In practical applications, the printed cards can be set to be sent out from the card outlet 12 or the card dispensing channel 19 as needed, thereby improving the diversity of card dispensing. For example, the card that was successfully printed can be output from the card outlet 12, and the card that failed to print can be output from the card dispensing channel 19. Alternatively, the card that was successfully printed can be output from the card dispensing channel 19, and the card that failed to print can be output from the card outlet 12. Of course, in some embodiments, the rotary drive mechanism 22 can also be controlled to rotate at a large angle, such as 90°, so that the card falls directly downwards.

[0053] During card printing, the user inputs the designed card information into the control system of the printing device. Then, the card feed drive mechanism 14 drives the card tray 11 to feed the blank card (located at the bottom) from the card inlet 13 into the rotary platform 20. The rotary platform 20 receives the card and the transfer conveyor 21 carries it forward to the printing platform 30. The card delivery drive mechanism 40 then carries the card and continues to drive its movement. During this movement, the printing device 50 prints the corresponding printing information on the upper surface of the card. If only one side needs to be printed, the card delivery drive mechanism 40 removes the card from the card outlet 12, completing the printing process. If a second side needs to be printed... The card is then driven to move in the reverse direction by the card feeding drive mechanism 14, returning the card to the rotating platform 20. The transfer conveyor 21 then receives and transports the card to the predetermined position. The rotating drive mechanism 22 then drives the rotating platform 20 to rotate approximately 180°, completing the card reversal process. The transfer conveyor 21 then drives the card to move to the printing platform 30, and the above process can be repeated to print on the second side of the card. This achieves automatic reversal and double-sided printing, improving printing intelligence and simplifying the overall control process. The device has a high degree of integration and is more suitable for self-service printing operations in self-service card vending machines.

[0054] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
