Description

Technical Field

[0001] The utility model relates to the technical field of traffic equipment, in particular to a card transmission mechanism and an autonomous card recovery and payment device having the same. Background Art

[0002] In recent years, unmanned automatic card issuance systems for entrance lanes have become increasingly widespread, significantly reducing highway operating costs and improving traffic efficiency. However, exit lanes still rely on manual, semi-automatic toll collection, requiring cash payment. This results in low traffic efficiency, and labor costs and highway operating costs continue to rise. To further reduce highway operating costs and improve traffic efficiency at toll booths, implementing unmanned toll payment systems in exit lanes has become an urgent need.

[0003] Existing high-speed automatic toll payment equipment includes separate card receiving and issuing machines, as well as integrated card receiving and issuing machines. Existing card receiving and issuing machines typically primarily comprise a housing, a card hopper, and a card transport device. Existing card transport devices generally consist of multiple rollers spaced apart in the transport direction. For example, Chinese patent publication number CN202230495U discloses an automatic card recovery device comprising a drive mechanism, transmission rollers, and a card receiving mechanism. The drive mechanism utilizes a drive motor, and the transmission rollers comprise a driving roller and a driven roller disposed in a corresponding upper and lower arrangement. A card transport channel for card transmission is formed between the driving roller and the driven roller. The roller pair formed by the driving roller and the driven roller is spaced apart along the card transport channel. The card receiving mechanism is located below the card transport channel and comprises a recovery box, a baffle, and a switching mechanism. The baffle is hinged to a frame, and the switching mechanism is mounted on the frame. The recovery box is located below the baffle, and the switching mechanism is located on one side of the baffle. The card transport mechanism of the aforementioned technical solution uses a multi-stage roller relay to achieve card movement within the transport channel. Longer card transport mechanisms require more rollers, which complicates the overall structure of the device and increases material and assembly costs. Furthermore, the multi-stage rollers are composed of corresponding upper and lower rollers, which places high demands on the wear resistance of the rollers, leading to higher costs.

[0004] Therefore, it is very necessary to provide a new card transmission mechanism to solve the above technical problems. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0031] A card transmission mechanism according to an embodiment of the present invention, specifically, see Figures 1 to 4 , including a mounting base 10, a driving mechanism 20 and a roller assembly 30. The mounting base 10 includes two support plates 11 and a fixing plate 12, wherein the two support plates 11 are arranged oppositely and spaced apart (i.e., as shown in FIG. Figure 5 As shown in the left and right), each support plate 11 is a piece of Figure 3 or Figure 4 For the convenience of description and distinction, one end of any support plate 11 is also shown as Figure 3 The right end shown is described as the first end (not labeled), and the other end is also Figure 3 The left end shown is described as the second end (not labeled). The fixed plate 12 is a square plate that is horizontally placed and fixed above the second ends of the two support plates 11. The drive mechanism 20 includes a conveyor belt assembly 21 and a drive assembly 22. The conveyor belt assembly 21 is located in the gap between the two support plates 11 and the transmission direction of the conveyor belt assembly 21 is consistent with the length direction of the support plates 11, that is, along the same direction as shown in FIG. Figure 3 or as Figure 4 The inner walls of the two support plates 11 and the upper surface of the conveyor belt assembly 21 define a card conveying channel 50 for conveying cards along the conveying direction. The direction of the card conveying channel 50 is also as shown. Figure 5The front-to-back direction shown, and as Figure 5 The rear end shown is used as a conveying port for cards to enter and / or exit the card conveying channel 50. The conveyor belt assembly 21 has two conveying ends, one corresponding to the first end of the support plate 11, which is defined as the first conveying end 2111 for ease of description and distinction. Figure 3 The right end shown in FIG. 1 corresponds to the second end of the support plate 11. Similarly, for ease of description and distinction, it is defined as the second delivery end 2112. Figure 3 As shown in the left end, the roller assembly 30 is movably arranged at the first end of the support plate 11 and is arranged above the first conveying end 2111, that is, it is arranged relative to the first conveying end 2111 in an upper and lower manner to define the above-mentioned conveying port. The movable arrangement here includes the roller assembly 30 rotating around its axis relative to the support plate 11, and also includes vertically moving up and down relative to the support plate 11 so that the roller assembly 30 approaches or moves away from the upper surface of the first conveying end 2111 of the conveyor belt assembly 21 to change the size of the conveying port according to the thickness of the card, that is, the opening of the conveying port is adjustable to accommodate the transmission of cards of different sizes, such as thickness, thereby improving applicability. The drive assembly 22 is transmission-connected to the second conveying end 2112, and the roller assembly 30 is transmission-connected to the first conveying end 2111 via the transmission component 40. In other words, the card transport mechanism of the embodiment of the present invention can achieve card transport through the cooperation of the conveyor belt assembly 21 and a roller assembly 30. Because the conveyor belt assembly 21 can serve as a card support at the bottom of the card conveying channel 50, there is no need to set supports in the middle position and the other end position of the card conveying channel 50, nor is there any need to add roller assemblies 30 in the middle and the other end positions. The conveyor belt assembly 21 serves as both a transport member and a support. Compared with the prior art mentioned in the background technology, the card transport mechanism of the embodiment of the present invention does not require the installation of multiple rollers 32 along the card conveying direction. Instead, it only requires the installation of a single roller 32 at one end of the conveyor belt assembly 21. This greatly reduces the complexity of the structure and also reduces costs. The structure is simple and practical.

[0032] According to some preferred embodiments of the present invention, Figure 3 and Figure 4 As shown, the roller assembly 30 includes a wheel shaft 31, at least one roller 32 and a transmission wheel. As shown in the figure, the wheel shaft 31 is an axis perpendicular to the card conveying direction, that is, along the direction of the card conveying. Figure 3 or Figure 4 As shown in the front-to-back direction, at least one roller 32 is coaxially sleeved on the axle 31 , that is, the number of the rollers 32 can be only one or more than one, such as two, three, etc. Figure 1 and Figure 2 In the example, there are two rollers 32, which are coaxial and spaced apart on the axle 31. The transmission wheel is fixed on one end of the axle 31, such as Figure 4 The front end shown. A conveying port is defined between the outer circumferential surface of the axle 31 and the upper surface of the first conveying end 2111 of the conveyor belt assembly 21. Preferably, the roller 32 in this embodiment of the present invention is a gear with inter-tooth grooves parallel to the axis of the axle 31. The gear surface is rough, resulting in high friction, which further facilitates the transfer of cards into and out of the card conveying channel 50. It should be noted that mounting holes 111 extending through the thickness of the support plates 11 are provided at the locations where the first ends of the two support plates 11 are rotatably connected to the corresponding ends of the axle 31. Bearings 34 are provided on either end of the axle 31 to rotatably engage with the corresponding mounting holes 111. The diameter of each mounting hole 111 is larger than the outer diameter of the corresponding bearing 34. When a card passes through the conveying port, the thickness of the card forces the roller 32 upward away from the upper surface of the first conveying end 2111, thereby enlarging the conveying port and facilitating smooth card passage and delivery. Bearings 34 are conventional bearings available on the market and are not specifically limited. When the card passes through the transfer port and enters the card conveying channel 50 and / or outside, the roller 32 will fall down under the action of gravity and reset. Further preferably, in order to facilitate the reset of the roller 32, a reset member is provided at at least one end of the wheel shaft 31. Figure 3 and Figure 4 As shown, there are two reset members, that is, one reset member is provided at each end of the wheel shaft 31. The reset member applies a biasing force to the wheel shaft 31 to reset the roller 32 on the wheel shaft 31 toward the upper surface of the first conveying end 2111. Preferably, the reset member of the embodiment of the utility model is a torsion spring 33. Figure 1 and Figure 2 As shown, a connecting post 331 (which may be a screw) is provided on the outer wall of the first end of each support plate 11, extending outward. A torsion spring 33 is sleeved onto the connecting post 331, with one end fixed to the wall of the support plate 11 (the wall may have a through-hole (not shown) for connecting one end of the torsion spring 33). The other end is attached to an annular groove (not shown) at one end of the axle 31. The provision of the torsion spring 33 allows for timely reset when no card is present at the transfer port, i.e., when a card has been delivered into or out of the card conveying channel 50 through the transfer port. As an alternative embodiment, the reset member may also be other reset member structures known to those skilled in the art that can similarly reset the axle 31 downward. The mounting hole 111 in this embodiment of the utility model may be a circular hole with an inner diameter slightly larger than the outer diameter of the bearing 34, or an elliptical hole with a major axis running vertically and a minor axis length equal to or slightly larger than the outer diameter of the bearing 34, without limitation.

[0033] like Figures 1 to 5As shown, the conveyor belt assembly 21 includes two conveyor shafts and a conveyor belt 211 wound between the two conveyor shafts in a closed loop. For ease of description and distinction, the two conveyor shafts are described as a first conveyor shaft 213 and a second conveyor shaft 212, respectively. The first conveyor shaft 213 corresponds to the first conveying end 2111, that is, both are in the same position. Figure 3 As shown in the right end, the second conveying shaft 212 corresponds to the second conveying end 2112, that is, both are as shown in FIG. Figure 3 The axial directions of the first conveying shaft 213 and the second conveying shaft 212 are perpendicular to the card conveying direction, that is, they are parallel to the axis of the wheel shaft 31 and are along the direction shown. Figure 3 The driving assembly 22 is connected to one end of the second conveying shaft 212. Figure 3 The driven wheel 2120 (synchronous belt 222 wheel) on the front end is shown to be transmission connected.

[0034] like Figure 2 and Figure 4 As shown, the transmission component 40 includes a first end of the first conveying shaft 213, namely Figure 4 The driving gear 41 on the front end shown and a driven gear 42 located on the wheel axle 31, the driven gear 42 being the above-mentioned transmission wheel. That is, the driving gear 41 and the driven gear 42 constitute the transmission component 40, and the driving gear 41 and the driven gear 42 are meshed and transmitted.

[0035] like Figures 1 to 3 As shown, the drive assembly 22 includes a drive motor 221 and a synchronous belt 222. More specifically, the drive motor 221 is a conventional servo motor currently available on the market. The drive motor 221 is fixed to the upper surface of the fixed plate 12. The drive end of the drive motor 221 is also as shown in FIG. Figure 3 A driving wheel 2210 (also a synchronous belt 222 wheel) is provided on the front end shown. The driving wheel 2210 and the driven wheel 2120 are staggered up and down. The synchronous belt 222 is connected between the driving wheel 2210 and the driven wheel 2120, forming an acute angle (such as 45°, 60°, etc.) with the horizontal line.

[0036] like Figures 1 to 4 As shown, it is further preferred that a baffle 60 is provided between the two support plates 11 and spans over the card conveying channel 50. The baffle 60 can play a role in longitudinally blocking and limiting the cards entering the card conveying channel 50, so as to prevent the cards from longitudinally jumping out of the card conveying channel 50. Specifically, at each end of the baffle 60, there is provided at least one protruding column 61 ( Figure 3 or Figure 4 There are two in the example), and correspondingly, at least one ( Figure 3 or Figure 4In the example, there are two track-shaped or waist-shaped limit grooves 112 extending vertically, and each boss 61 is slidably disposed in a limit groove 112. With such a design, the height position of the baffle 60 can be adjusted according to the thickness of the card.

[0037] The present invention also provides an autonomous card collection and payment device, including the card transfer mechanism of the aforementioned embodiment. Of course, other common components may also be included, such as a housing, a card collection bin disposed within the housing and below the card transfer mechanism, and the like, but these are not specifically described or limited herein. Since the card transfer mechanism of the aforementioned embodiment is included, the device at least exhibits the beneficial effects of the aforementioned card transfer mechanism, and therefore will not be further elaborated upon here.

[0038] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
