Description

Technical Field

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] First embodiment:

[0035] See Figures 1-7 This card issuing machine includes a main body 1, which has an electrical cavity 11 and a material bin 12. The front and rear sides of the material bin 12 respectively form a card dispensing area for dispensing card paper 2 and a card storage area for storing card paper 2. The front side of the card dispensing area has a card dispensing port 121. The electrical cavity 11 is provided with a drive module that enables the card paper 2 to move towards the card dispensing port 121. The drive module includes a main drive assembly and a secondary drive assembly. The main drive assembly and the secondary drive assembly respectively include a main feeding roller 31 disposed in the card dispensing area and a secondary feeding roller 41 disposed in the card storage area. The secondary feeding roller 41 and the main feeding roller 31 respectively push the card paper 2 towards the card dispensing port 121 through forward rotation. The linear velocity of the main feeding roller 31 is greater than or equal to the linear velocity of the secondary feeding roller 41.

[0036] The card storage area usually has several card pieces 2 stacked together. When card pieces 2 need to be distributed, the bottom card piece 2 first moves to the card dispensing area under the action of the auxiliary feeding roller 41, and then the card piece 2 is distributed outward from the card dispensing port 121 by the main feeding roller 31.

[0037] Since the linear speed of the main feeding roller 31 is greater than or equal to the linear speed of the auxiliary feeding roller 41, there will be a time difference between the time when the paper card 2 adjacent to the bottommost paper card 2 reaches the card outlet 121, thereby reducing the chance of two or more paper card 2 entering the card outlet 121 at the same time and causing jamming.

[0038] Of course, the operating logic of the main feeding roller 31 and the auxiliary feeding roller 41 can be further optimized. For example, when the bottom card 2 enters the card output area, the auxiliary feeding roller 41 stops rotating until the bottom card 2 is completely dispatched from the card output port 121, and then the auxiliary feeding roller 41 restarts to push the other card 2 to the card output area.

[0039] The main feeding roller 31 and the auxiliary feeding roller 41 in the card dispensing area and the card storage area respectively cooperate to reduce the chance of stacked card jam pieces 2 entering the card dispensing port 121 at the same time, making it less likely for card jam pieces 2 to get stuck in the card dispensing port 121, thus improving the stability of equipment operation.

[0040] Furthermore, the main drive assembly includes a main drive motor 32 and a main reduction gear set 33. The main drive motor 32, the main reduction gear set 33, and the main feeding roller 31 are respectively disposed in the electrical cavity 11. The radial outer side of the main feeding roller 31 extends into the hopper 12 at least partially. The main drive motor 32 drives the main feeding roller 31 to rotate forward through the main reduction gear set 33. The main reduction gear set 33 can form a suitable reduction ratio between the main drive motor 32 and the main feeding roller 31, so that the main feeding roller 31 rotates at a relatively lower speed than the main drive motor 32.

[0041] The auxiliary drive assembly includes an auxiliary drive motor 42 and an auxiliary reduction gear set 43. The auxiliary drive motor 42, the auxiliary reduction gear set 43, and the auxiliary feeding roller 41 are respectively disposed in the electrical cavity 11. The radial outer side of the auxiliary feeding roller 41 extends into the hopper 12 at least partially. The auxiliary drive motor 42 drives the auxiliary feeding roller 41 to rotate in the forward or reverse direction through the auxiliary reduction gear set 43. The auxiliary reduction gear set 43 can form a suitable reduction ratio between the auxiliary drive motor 42 and the auxiliary feeding roller 41, so that the auxiliary feeding roller 41 rotates at a relatively lower speed than the auxiliary drive motor 42.

[0042] In practical use, in order to further reduce the chance of two or more card pieces 2 entering the card outlet 121 at the same time and causing jamming, the auxiliary drive motor 42 can also cause the auxiliary feeding roller 41 to rotate in the opposite direction by a small stroke, so that the card piece 2 adjacent to the bottom card piece 2 is further away from the card outlet 121, thereby reducing the chance of two or more card pieces 2 entering the card outlet 121 at the same time and causing jamming.

[0043] The number of main feeding rollers 31 and auxiliary feeding rollers 41 can also be adjusted according to the actual situation. When the card dispenser needs to dispense wider card pieces 2, multiple feeding rollers 31 and auxiliary feeding rollers 41 can be set in the main material bin along the left and right directions.

[0044] Furthermore, the main reduction gear set 33 is disposed in the space between the main drive motor 32 and the main feeding roller 31. The main reduction gear set 33 includes a number of main reduction gears connected and engaged in sequence. The main drive motor 32 has a main drive gear 321, which is connected and engaged with the adjacent main reduction gear. There are two or more main reduction gears. The width of the main reduction gear in the vertical direction is smaller than the width of the main drive motor 32 in the vertical direction. The shaft of the main drive motor 32 is arranged in the horizontal direction. The adjacent and interconnected main reduction gears are distributed in the horizontal direction and staggered in the front-back direction. The main feeding roller 31 has a main drive gear 311, which is connected and engaged with the adjacent main reduction gear.

[0045] The active reduction gear set 33 can make full use of the space in the left-right and front-back directions within the electrical cavity 11. Therefore, the maximum diameter of each main reduction gear can be relatively reduced. Compared with the existing technology that uses belt pulley transmission, it is not necessary to significantly increase the vertical height of the electrical cavity 11, so that the overall volume of the equipment can be relatively reduced. At the same time, the number of main reduction gears is relatively increased within a certain space, achieving a higher speed ratio.

[0046] The auxiliary reduction gear set 43 is located in the space between the auxiliary drive motor 42 and the auxiliary reduction gear set 43. The auxiliary reduction gear set 43 includes several auxiliary reduction gears that are connected and engaged in sequence. The auxiliary drive motor 42 has an auxiliary drive gear, which is connected and engaged with the adjacent auxiliary reduction gear. There are two or more auxiliary reduction gears. The width of the auxiliary reduction gear in the vertical direction is smaller than the width of the auxiliary drive motor 42 in the vertical direction. The shaft of the auxiliary drive motor 42 is set in the horizontal direction. The adjacent auxiliary reduction gears that are connected and engaged in the horizontal direction are distributed in the horizontal direction and are staggered in the front-back direction. The auxiliary feeding roller 41 has an auxiliary drive gear 411, which is connected and engaged with the adjacent auxiliary reduction gear.

[0047] The auxiliary reduction gear set 43 can make full use of the space in the left and right and front and back directions within the electrical cavity 11. Therefore, the maximum diameter of each auxiliary reduction gear can be relatively reduced. Compared with the existing technology that uses belt pulley transmission, it is not necessary to significantly increase the vertical height of the electrical cavity 11, so that the overall volume of the equipment can be relatively reduced. At the same time, the number of auxiliary reduction gears is relatively increased within a certain space, achieving a higher speed ratio.

[0048] The electrical cavity 11 is provided with a first enclosure 111 and a second enclosure 112. The inner sides of the first enclosure 111 and the second enclosure 112 respectively form a first assembly space and a second assembly space. The main feeding roller 31, the main drive motor 32 and the main reduction gear set 33 are respectively arranged in the first assembly space, and the auxiliary feeding roller 41, the auxiliary drive motor 42 and the auxiliary reduction gear set 43 are respectively arranged in the second assembly space. The first assembly space and the second assembly space can make it easier to install the drive module in the electrical cavity 11. At the same time, under the action of the first enclosure 111 and the second enclosure 112, the noise generated by the main drive assembly and the auxiliary drive assembly during operation can be relatively reduced.

[0049] Preferably, sealing caps (not shown in the figure) can be provided on the first assembly space and the second assembly space, and then grease can be filled in the first assembly space and the second assembly space, so that the linkage between different components of the drive module is smoother and the grease is less likely to overflow.

[0050] Furthermore, the main feeding roller 31 and the auxiliary feeding roller 41 are similar in shape and size, the main drive motor 32 and the auxiliary drive motor 42 are motor devices of the same model, and the main reduction gear set 33 and the auxiliary reduction gear set 33 have the same gear ratio, which helps to reduce the assembly difficulty. At the same time, the motor devices are of the same model, and the main reduction gear set 33 and the auxiliary reduction gear set 33 have the same gear ratio. Therefore, when it is necessary to control the speed of the main feeding roller 31 and the auxiliary feeding roller 41, it is only necessary to control the input power of the main drive motor 32 and the auxiliary drive motor 42, making the control logic simpler.

[0051] Furthermore, the main body 1 is provided with a sensing device for sensing the passage of the card 2 at the position corresponding to the card slot 121, and the electrical cavity 11 is provided with a control circuit board 5, which is electrically connected to the sensing device and the drive module respectively.

[0052] The control circuit board 5 can more precisely control the drive module based on the state of the paper card 2 passing through the card outlet 121 as sensed by the sensing device. For example, at the beginning, the main drive motor 32 and the auxiliary drive motor 42 start working. When the bottom paper card 2 begins to pass through the card outlet 121, the sensing device feeds back to the control circuit board 5. The control circuit board 5 controls the rotation speed of the auxiliary drive motor 42 to be further reduced or reversed by a relatively short distance, so that the time difference between the paper card 2 adjacent to the bottom paper card 2 and the bottom paper card 2 reaching the card outlet 121 is further increased, thereby further reducing the chance of two or more paper cards 2 entering the card outlet 121 at the same time and causing jamming.

[0053] Furthermore, the sensing device includes an upper photosensitive probe 61 and a lower photosensitive probe 62, which are respectively disposed above and below the card outlet 121 on the main body 1. The upper photosensitive probe 61 and the lower photosensitive probe 62 determine whether the card piece 2 has passed through the card outlet 121 through light signals. When the card piece passes through the card outlet 121, the light signal between the upper photosensitive probe 61 and the lower photosensitive probe 62 is interrupted. At this time, the sensing device can send feedback to the control circuit board 5 that the card piece 2 has passed through the card outlet 121 until the light signal is reconnected. At this time, it can be determined that the card piece 2 has completely left the card outlet 121.

[0054] The main body 1 is provided with a guide groove 14 and a limiting buckle 15 corresponding to the upper photosensitive probe 61. The main body 1 of the upper photosensitive probe 61 is in the shape of a long plate. The outer side of the upper photosensitive probe 61 is slidably engaged with the guide groove 14. The upper photosensitive probe 61 is provided with a limiting hole corresponding to the limiting buckle 15. The limiting buckle 15 engages with the limiting hole to fix the upper photosensitive probe 61 to the main body 1. The engagement of the limiting buckle 15 with the limiting hole fixes the upper photosensitive probe 61 to the main body 1, thereby achieving a quick installation effect between the upper photosensitive probe 61 and the main body 1.

[0055] Furthermore, the lower photosensitive probe 62 is installed and fixed inside the electrical cavity 11, and the main body 1 is provided with a light guide hole 16 for light to pass through at the position corresponding to the upper side of the lower photosensitive probe 62, which can make better use of the space inside the electrical cavity 11.

[0056] Furthermore, a guide ramp 122 is provided in the hopper 12 on the side of the main feeding roller 31 facing away from the card outlet 121. The guide ramp is inclined from bottom to top along the direction from the card outlet area to the card outlet 121. When the bottom card piece 2 passes through the guide ramp 122, it will be lifted upward. The bottom card piece 2 can block the card pieces 2 stacked above it to a certain extent, reducing the chance that the card pieces 2 stacked above and the bottom card piece 2 will enter the card outlet 121 at the same time.

[0057] Furthermore, a pressing block 7 is provided above the main feeding roller 31 on the main body 1. The pressing block 7 is detachable from the main body 1. The bottom of the pressing block 7 and the main feeding roller 31 form a card dispensing gap for the card paper to pass through. The pressing block 7 can form card dispensing gaps of different widths by adjusting its relative position with the main body 1 in the vertical direction and connecting and fixing it with the locking mechanism. The locking mechanism includes an adjusting elongated hole 72 provided on the pressing block 7 and a screw hole provided on the main body 1. The adjusting elongated hole 72 can be locked and fixed with the screw hole at different vertical positions by screws. The card dispenser can be adapted to card paper 2 of different thicknesses.

[0058] Furthermore, the clamping block 7 is connected to an elastic element 8 for pushing the clamping block 7 toward the main feeding roller 31. A limiting post 71 is provided on the upper side of the clamping block 7, and the elastic element 8 is located on the outside of the limiting post 71. The upper and lower ends of the elastic element 8 are respectively connected and cooperated with the main body 1 and the clamping block 7.

[0059] When the card dispenser needs to load a new card part 2, the screws can be loosened first, and a single card part 2 can be placed at the card outlet 121. The clamping block 7 clamps the card part 2 under the action of the elastic element 8. Then, the relative position between the clamping block 7 and the main body 1 is fixed again by the screw, the adjusting elongated hole 72 and the screw hole. Since the width of the card outlet gap can be adapted to the card part 2 with a high degree under the action of the clamping block 7, the chance of multiple card parts passing through the card outlet gap can be further reduced.

[0060] Furthermore, the bottom of the clamping block 7 is arc-shaped, which improves the smoothness of the paper card 2 when it passes through the clamping block 7.

[0061] Second embodiment:

[0062] See Figure 8 The difference between this embodiment and the first embodiment is that the main feeding roller 31 of this card issuing machine is a roller with a circular cross-section, and the auxiliary feeding roller 41 is an eccentric wheel. Since the card piece 2 has a certain thickness, when the bottom card piece 2 is not completely separated from the adjacent card piece 2, the auxiliary feeding roller 41 can better contact the adjacent card piece 2, thereby pushing the adjacent card piece 2 to move.

[0063] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0064] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
