The present invention will be described in further detail with reference to examples and drawings, but embodiments of the present invention are not limited thereto.

Example 1

Referring to fig. 1 to 6, the horizontally arranged self-service card-receiving machine of the present invention comprises a case D, a card compartment for storing a smart card, a card issuing device C for sending an external smart card into the card compartment, a card taking device J for taking out and sending the smart card in the card compartment to a user, an old card recycling device a for recycling an old card, an identification device F for identifying user identification information, and a display screen H; the card bin, the card issuing device C, the card taking device J and the old card recycling device A are all arranged in the case D, and the identity recognition device F and the display screen H are arranged outside the case D; the card bin comprises a plurality of smart card storage devices B which are horizontally arranged, and the smart card storage devices B are sequentially stacked along the vertical direction; the intelligent card storage device B comprises a storage rack 1B, a card storage mechanism 3B and an intelligent card conveying mechanism for driving the card storage mechanism 3B to do circular motion on a horizontal plane, wherein the intelligent card conveying mechanism comprises a first conveying belt 2B which is wound into a closed ring shape in the horizontal plane and a first driving mechanism 4B for driving the first conveying belt 2B to do circular motion, and the first driving mechanism 4B is arranged on the storage rack 1B; the card storing mechanism 3b comprises a plurality of first card boxes 3-1b which are uniformly distributed along the conveying direction of the first conveying belt 2b, and the first card boxes 3-1b are connected with the first conveying belt 2b through a connecting component; a plurality of card storage spaces 3-2b for storing smart cards are arranged in the first card box 3-1 b.

Referring to fig. 5, 6 and 9, the first driving mechanism 4b includes a driving motor 4-1b, a first driving synchronizing wheel 4-2b and a first driven synchronizing wheel 4-3b, wherein the first driving synchronizing wheel 4-2b is installed at one end of the storage rack 1b, the first driven synchronizing wheel 4-3b is installed at the other end of the storage rack 1b, and the first conveyor belt 2b is a synchronous conveyor belt, and the synchronous conveyor belt is looped between the first driving synchronizing wheel 4-2b and the first driven synchronizing wheel 4-3 b; the main shaft of the driving motor 4-1b is connected with the first driving synchronous wheel 4-2 b. The first conveying belt 2b is driven to rotate by the driving motor 4-1b, so that the first card box 3-1b arranged on the first conveying belt 2b is driven to move, and any card storage space 3-2b on the first card box 3-1b can reach the first card inlet opening 1-5b or the first card outlet opening 1-4b.

Referring to fig. 5-13, the first card box 3-1b is provided with first grooves 3-4b communicating with the card storage space 3-2b at two sides perpendicular to the card in-out direction, each first groove 3-4b is internally provided with an elastic positioning piece 3-3b for elastically clamping and positioning the smart card, wherein the two first grooves 3-4b are symmetrically distributed on the first card box 3-1b and extend from the front end to the rear end of the first card box 3-1b, and the elastic positioning pieces 3-3b in the two first grooves 3-4b are clamped at two sides of the smart card. Thus, when the first conveyor belt 2b drives the first cassette 3-1b to enter the circular arc section where the first conveyor belt 2b contacts the first driving synchronous wheel 4-2b or the first driven synchronous wheel 4-3b, the movement direction of the first cassette 3-1b gradually transits to reverse movement, and when the first cassette 3-1b leaves the circular arc section where the first conveyor belt 2b contacts the first driving synchronous wheel 4-2b or the first driven synchronous wheel 4-3b, the movement direction of the first cassette 3-1b is opposite to the previous movement direction. During this process, the smart card stored in the first card case 3-1b is also shifted parallel to the moving direction due to inertia, and even the smart card is caused to drop from the card storage space 3-2 b. Therefore, the elastic positioning members 3-3b are provided so that both sides of the smart card in the card storage space 3-2b are locked, thereby preventing the smart card from being shifted or dropped in parallel to the moving direction of the first conveyor belt 2b during the conveying process. In addition, in the process that the card issuing device C sends the smart card to the card storing space 3-2b, the elastic positioning piece 3-3b can provide an elastic damping effect for the smart card, so that the smart card is prevented from shifting the position of the smart card in the card storing space 3-2b due to overlarge inertia, and the position of the smart card in the card storing space 3-2b is more accurate.

Referring to fig. 5-13, the elastic positioning member 3-3b is composed of a circular arc-shaped elastic baffle, one end of the circular arc-shaped elastic baffle is mounted on the first card box 3-1b, and the other end extends inwards from the first groove 3-4b and contacts with the smart card. In this way, in the process that the card sender C sends the smart card to the card storage space 3-2b of the first card box 3-1b, the two sides of the smart card are contacted with the circular arc-shaped elastic blocking pieces on the two sides of the card storage space 3-2b and press the circular arc-shaped elastic blocking pieces, so that the circular arc-shaped elastic blocking pieces move outwards in a direction away from the smart card, and in the process, the circular arc-shaped elastic blocking pieces on the two sides move reversely in a direction away from the smart card, so that the smart card smoothly enters the card storage space 3-2b, and the circular arc-shaped elastic blocking pieces on the two sides clamp the smart card for restoring, so that the smart card is prevented from being offset parallel to the moving direction in the process of moving along with the direction change of the first card box 3-1 b.

Referring to fig. 8-13, the connection assembly comprises two connection blocks 3-13b symmetrically arranged on a first card box 3-1b, wherein each connection block 3-13b comprises a first clamping part 3-7b, a second clamping part 3-8b and a second groove 3-11b arranged between the first clamping part 3-7b and the second clamping part 3-8b, and a first through hole 3-10b communicated with the second groove 3-11b is arranged on the first clamping part 3-7b and the second clamping part 3-8 b; the first conveying belt 2b is embedded in the second groove 3-11b, the first clamping part 3-7b is embedded in a tooth slot between two first conveying belt synchronous teeth 2-2b of the first conveying belt 2b, a second through hole 2-1b is arranged at a position corresponding to the first through hole 3-10b of the first conveying belt 2b, and the second through hole 2-1b is connected with the first through hole 3-10b through a screw rod 3-9 b. In this way, the first cassette 3-1b is mounted on the first conveyor belt 2b through the connection block 3-13b and moves along with the movement of the first conveyor belt 2b, because the contact between the first cassette 3-1b and the first conveyor belt 2b is close to a line contact, when the first conveyor belt 2b drives the first cassette 3-1b to enter a circular arc section of the first conveyor belt 2b contacting the first driving synchronous wheel 4-2b or the first driven synchronous wheel 4-3b, the first cassette 3-1b can smoothly bend along with the first conveyor belt 2 b.

Referring to fig. 5 and 6, the storage rack 1b includes a base 1-3b, a first support plate 1-1b and a second support plate 1-2b disposed on the base 1-3b, wherein the first driving mechanism 4b is mounted on the first support plate 1-1b and the second support plate 1-2b, and both sides of the first conveyor belt 2b are respectively in contact with the first support plate 1-1b and the second support plate 1-2 b. In this way, the first supporting plate 1-1b and the second supporting plate 1-2b limit the two sides of the first conveying belt 2b, so that the situation that the conveying precision of the intelligent card conveying mechanism is not high due to the fact that the first conveying belt 2b moves in the moving process is avoided. In addition, the storage rack 1b is compact in structure and good in supporting effect.

Referring to fig. 7, 8 and 11, a lateral anti-swing mechanism for preventing the first cartridge 3-1b from swinging laterally on a horizontal plane is arranged between the first cartridge 3-1b and the storage rack 1b, wherein the lateral anti-swing mechanism comprises a first limit wheel 3-5b installed on two sides of the first cartridge 3-1b and a third groove 1-7b arranged on the storage rack 1b, and the width of the third groove 1-7b is consistent with the diameter of the first limit wheel 3-5 b; the third groove 1-7b is arranged at a position corresponding to the first inlet opening 1-5b and the first outlet opening 1-4b in the storage rack 1b, and when the first conveying belt 2b drives the first card box 3-1b to move to the first inlet opening 1-5b and the first outlet opening 1-4b, the first limiting wheel 3-5b is matched with the third groove 1-7 b. In the process that the first conveyor belt 2b drives the first card box 3-1b to move to the first card inlet 1-5b or the first card outlet 1-4b to store or take cards, as the first conveyor belt 2b is a flexible body, flexible deformation easily occurs in the moving process, so that the first card box 3-1b swings horizontally, which results in that the card storage space 3-2b of the first card box 3-1b reaching the first card inlet 1-5b or the first card outlet 1-4b is separated from the first card inlet 1-5b or the first card outlet 1-4b, so that not only the card issuing device C cannot send smart cards from the first card inlet 1-5b to the card storage space 3-2b of the first card box 3-1b, but also the card taking device J cannot take smart cards out from the card storage space 3-2b of the first card box 3-1b through the first card outlet 1-4 b. This problem is thus well solved by providing the above-mentioned lateral anti-sway mechanism, when the first cartridge 3-1b arrives at the first outlet opening 1-4b or the first inlet opening 1-5b with the first conveyor belt 2b, the first limit wheel 3-5b enters into the third recess 1-7b, and since the diameter of the first limit wheel 3-5b coincides with the width of the third recess 1-7b, the first limit wheel 3-5b cannot be deflected in the direction parallel to the end face of the first limit wheel 3-5b during the movement in the third recess 1-7b, so that the lateral sway of the first cartridge 3-1b connected to the first limit wheel 3-5b on the horizontal plane is restricted, and the first cartridge 3-1b always coincides with the first inlet opening 1-5b or the first outlet opening 1-4b with the first conveyor belt 2b, when the first cartridge 3-1b arrives at the first inlet opening 1-5b or the first outlet opening 1-4b, and the first cartridge 3-1b is always aligned with the first outlet opening 1-5 b. Thereby improving the conveying precision of the intelligent card conveying mechanism, enabling the external intelligent card to smoothly enter the first card box 3-1b and enabling the intelligent card in the first card box 3-1b to smoothly send out from the first card outlet opening 1-4 b.

Referring to fig. 7, 8 and 11, a plurality of sets of vertical anti-swing mechanisms for preventing the first card box 3-1b from swinging vertically are further arranged between the first card box 3-1b and the storage rack 1b, each set of vertical anti-swing mechanisms comprises a second limiting wheel 3-6b arranged on two sides of the first card box 3-1b and perpendicular to the first limiting wheel 3-5b, and a guide plate 1-6b arranged on the storage rack 1b, the guide plate 1-6b is arranged on two sides of a first outlet opening 1-4b and a first inlet opening 1-5b, and the second limiting wheel 3-6b and the first limiting wheel 3-5b are arranged on the same side of the first card box 3-1 b; the guide plate 1-6b is provided with a limiting surface matched with the second limiting wheel 3-6b, and when the first card box 3-1b moves to the first card outlet opening 1-4b or the first card inlet opening 1-5b, the second limiting wheel 3-6b is matched with the limiting surface. In the process that the first conveying belt 2b drives the first card box 3-1b to move to the first card inlet 1-5b or the first card outlet 1-4b to store or take cards, as the first conveying belt 2b is a flexible body, flexible deformation is easy to occur in the moving process, the first card box 3-1b can transversely swing on the horizontal plane and can swing vertically more easily, and the card storage space 3-2b of the first card box 3-1b reaching the first card inlet 1-5b or the first card outlet 1-4b is staggered with the first card inlet 1-5b or the first card outlet 1-4b, so that card storage work or card taking work cannot be smoothly performed. Therefore, this problem can be well solved by setting the vertical anti-swing mechanism, when the first card box 3-1B moves to the first card inlet opening 1-5B or the first card outlet opening 1-4B along with the first conveying belt 2B, the second limit wheels 3-6B on two sides of the first card box 3-1B are respectively contacted with the limit surfaces on two sides of the first card outlet opening 1-4B or the first card inlet opening 1-5B, so that the first card box 3-1B connected with the second limit wheels 3-6B is prevented from shifting in the direction parallel to the end surface of the second limit wheels 3-6B, the accuracy of card storage and card taking of the smart card storage device B is ensured, and further the card collecting work and the card issuing work are ensured to be smoothly carried out.

The first connecting plate 1-5a and the second connecting plate 1-6a are beneficial to improving the stability of the first box body 1a and better ensuring that the old card stored in the old card recovery box 2A does not deviate.

Referring to fig. 24-28, a plurality of clamping grooves 4a uniformly distributed along the conveying direction of the conveying belt are formed on the outer surfaces of the second conveying belt 2a and the third conveying belt 5a, and when the driving mechanism drives the second conveying belt 2a and the third conveying belt 5a to rotate in the same speed and in opposite directions, the clamping grooves 4a on the second conveying belt 2a are parallel to and in one-to-one correspondence with the clamping grooves 4a on the third conveying belt 5 a. Because the old cards are stored in the card slots 4a on the two opposite surfaces of the second conveying belt 2A and the third conveying belt 5a, after the old card recovery card box 2A collects the old cards, the old card recovery card box 2A conveys the old cards to the second card outlet opening, the external recovery device takes away the old cards at the second card outlet opening of the old card recovery card box 2A, and then the moving mechanism drives the second conveying belt 2A and the third conveying belt 5a to continue to move reversely, so that the next old card continues to reach the second card outlet opening of the old card recovery card box 2A, and the external recovery device can take all the old cards inside the old card recovery card box 2A only by repeating card taking actions. At this time, the card slot 4a on the opposite surface of the second conveyor belt 2A and the third conveyor belt 5a reaches the other side along with the constant-speed reverse rotation of the second conveyor belt 2A and the third conveyor belt 5a, so that the card slot 4a on the opposite surface of the second conveyor belt 2A and the third conveyor belt 5a is not provided, when the old card recovery card box 2A is used again by an operator to collect the old card, the positions of the card slots 4a on the second conveyor belt 2A and the third conveyor belt 5a need to be adjusted first so that the card slots reach the second card inlet of the old card recovery card box 2A along with the constant-speed reverse movement of the second conveyor belt 2A and the third conveyor belt 5a, and thus a new round of old card collection work is started. Because the old card recovery card box 2A needs an operator to adjust the card storage space in the old card recovery card box 2A after one card recovery and card issuing, when the next round of card recovery work is carried out, the card storage space moves to the second card outlet from the second card inlet of the old card recovery card box 2A to the second card outlet along with the second conveying belt 2A and the third conveying belt 5a when the next round of card recovery work is carried out, so that the workload of the operator is increased, and the efficiency is reduced. Therefore, the above structure well solves the problem, since the card slots 4a are uniformly distributed on the outer surfaces of the second conveyor belt 2A and the third conveyor belt 5a, the old card recovery card box 2A can be directly used for collecting the old card without adjusting the old card if the next round of card recovery is needed even after the old card recovery card box 2A passes through a round of card recovery and card issuing, thus not only improving the working efficiency, but also reducing the workload of operators. In addition, a card cover is arranged outside the old card recovery card box 2A, wherein the card cover is provided with openings at the second inlet opening and the second outlet opening of the old card recovery card box 2A. This prevents dust from outside from entering the inside of the old card recovery cassette 2A, thereby affecting the card receiving and issuing accuracy of the old card recovery cassette 2A.

Referring to fig. 1-4, a side door 1D for opening is arranged on one side of the case D; the case D is provided with a back door 2D at a position corresponding to the card issuing device C. The purpose of setting the side door 1D is to facilitate the monitoring and maintenance of the self-service card-receiving machine by operators. The above-described rear door 2D is provided for the purpose of facilitating the installation of the second card case 1C onto the card issuing device C by the operator.

Referring to fig. 1 and 2, the case D is provided with a card taking box G. Thus, after the user inputs the identity information of the user into the self-service card-receiving machine, the card-taking device J takes the smart card matched with the user information out of the smart card storage device B and sends the smart card to the card-taking box G.

Referring to fig. 1-4, the information input device F includes an identification card information reading module, a fingerprint identification module, and a keyboard. Therefore, in the process of picking up the card, the identity card of the user is required to be placed in the identity card information reading module to read the identity card information, the finger of the user is required to be placed on the fingerprint identification module, whether the person picking up the card and the holder of the identity card are the same person or not is judged by identifying the fingerprint, and the smart card belonging to the user can be taken from the self-service card picking machine only when the person picking up the card holds the effective identity card before picking up the card, so that the card taking safety is greatly improved.

Referring to fig. 1-4, the self-service card-receiving machine further includes a camera E and a printer I for printing the list.

Referring to fig. 1-4, the card extracting device J is implemented according to the invention patent application with application publication number CN106127270 a.

Referring to fig. 1 to 28, the working principle of the horizontally arranged self-service card-receiving machine of the invention is as follows:

before working, the operator installs the second card case 1C on the card sender C, at this time, the support column 3-2 enters the seventh groove 7-8 on the sixth support plate 7-1 and continues to move transversely, the circular arc guide surface 7-7 of the sixth support plate 7-1 contacts with the circular arc protrusion 3-8 of the elastic stop 3-5 and presses the elastic stop 3-5 upwards, thereby generating a vertical component force to the elastic stop 3-5, so that the elastic stop 3-5 on both sides moves reversely in the direction away from the card sender C3-1, when the elastic stop 3-5 on both sides moves a certain distance, the locking surface 3-9 of the elastic stop 3-5 on both sides leaves the abutting surface 3-10 of the card sender C3-1, at the same time, the sixth support plate 7-2 continues to move transversely when the support column 3-2 reaches the bottom of the seventh groove 7-8, so that the sixth support plate 7-1 generates a pressure opposite to the direction of the support column 3-2, thereby driving the support column 3-2 and the card sender C3-2 to move transversely in the direction, thereby driving the card sender C1 to move transversely in the card sender C1, and then the card sender C1 is driven by the second card sender C1, and the second card sender C1 is pushed by the second card sender C1, and the third card sender C1 is pushed by the second card sender C1, so that the second smart card at the bottommost end of the second card box 1C reaches the original position of the first smart card, and the card pulling mechanism 8 repeats the card pulling action, thereby sending out the smart card in the second card box 1C. After the smart card in the second card box 1C is sent out, the operator takes out the second card box 1C, and in this process, the support column 3-2 gradually leaves the seventh groove 7-8 on the sixth support plate 7-1, so that the circular arc guiding surface 7-7 of the sixth support plate 7-1 is gradually separated from the circular arc protrusion 3-8 of the elastic stop block 3-5, so that the elastic stop blocks 3-5 on two sides gradually move towards each other for restoring the original shape. When the support column 3-2 completely leaves the seventh groove 7-8, the locking surfaces 3-9 of the elastic stoppers 3-5 on both sides are attached to one side of the attaching surface 3-10 on the card discharging baffle 3-1 again, so as to close the third card discharging opening 4 of the second card box 1C.

Because the first card inlet opening 1-5B for storing the smart card into the first card box 3-1B and the first card outlet opening 1-4B for taking out the smart card in the first card box 3-1B are arranged on the outer side of the smart card storage device B, the poking tooth driving mechanism drives the poking tooth 8-10 to move, so that the smart card at the bottommost end of the second card box 1C is sent to the first card inlet opening 1-5B, and meanwhile, the first driving mechanism 4B drives the first conveying belt 2B and the first card box 3-1B thereon to move, so that a card storage space 3-2B to be stored in the smart card box 3-1B reaches the first card inlet opening 1-5B, and then, the poking tooth driving mechanism drives the poking tooth 8-10 to move, so that the smart card positioned in the first card inlet opening 1-5B enters the card storage space 3-2B. Subsequently, the first driving mechanism 4b continues to drive the first conveying belt 2b and the first card box 3-1b thereon to move, so that the next card storage space 3-2b to be stored in the smart card reaches the first card inlet opening 1-5b, the card pulling mechanism 8 repeats the card pulling action, and sends the next smart card to the card storage space 3-2b, and the above process is repeated continuously, so that the smart card can be continuously transferred into the card storage mechanism 3 b.

When the user needs to pick up the smart card, the user needs to put the old card into the old card sending mechanism 1A, the old card sending mechanism 1A sends the old card to the second card inlet of the old card recycling card box 2A, and then the reverse driving mechanism drives the second conveying belt 2A and the third conveying belt 5a to do constant-speed reverse motion, so that the card storage space reaches the second card inlet, and at the moment, the old card reaching the second card inlet enters the card storage space of the old card recycling card box 2A under the thrust of the old card sending mechanism 1A. Subsequently, the reverse driving mechanism drives the second conveyor belt 2A and the third conveyor belt 5a to perform a constant-speed reverse movement toward the other end of the old card recovery cassette 2A, so that the next card storage space constituted by the corresponding and parallel card slots 4a of the opposite outer surfaces of the second conveyor belt 2A and the third conveyor belt 5a reaches the second card inlet opening, ready for storing the next old card. Then, the user puts the own identity card on the identity card information reading module, the self-service card-picking machine reads the identity information of the user, then the user presses the fingers of the user on the fingerprint identification module, the self-service card-picking machine reads the fingerprint information and judges whether the person held by the identity card and the card-picking person are the same person, if the person is the same person, the first driving mechanism 4b drives the first conveying belt 2b and the first card box 3-1b thereon to move, so that the card storage space 3-2b of the smart card matched with the user information in the first card box 3-1b reaches the first card outlet opening 1-4b, and then the card taking device J takes the smart card positioned in the first card outlet opening 1-4b out of the card storage space 3-2b and sends the smart card to the user.

Example 2

Referring to fig. 29, the present embodiment is different from embodiment 1 in that the synchronous transmission mechanism 7a includes a first driving pulley 7-5a connected to a main shaft of a reverse motor 8a, a first driven pulley 7-6a connected to a second driving synchronous pulley 3-1a through a first connecting shaft 7-2a, a second driven pulley 7-7a connected to a third driving synchronous pulley 6-1a through a second connecting shaft 7-4a, a transmission shaft 7-8a provided on one side of the first driven pulley 7-5a or the second driven pulley 7-7a, and a transmission belt wound around the first driving pulley 7-5a, the first driven pulley 7-6a, the second driven pulley 7-7a, and the transmission shaft 7-8 a. The structure can realize the constant-speed and reverse rotation of the first driven driving belt pulley 7-6a and the second driven driving belt pulley 7-7a, so that the second conveying belt 2a and the third conveying belt 5a can rotate at the same speed and reverse, and the synchronous driving mechanism 7a has a simple structure and strong driving force.

Example 3

Referring to fig. 30, this embodiment is different from embodiment 1 in that the elastic stopper 3-5 is provided with an inclined surface 3-11 inclined outwardly in a direction away from the elastic stopper 3-5, and one end of the inclined surface 3-11 is connected to the circular arc surface and the other end is connected to the locking surface 3-9. In the process that the second card box 1C leaves the card issuing device C, after the acting force exerted on the supporting column 3-2 disappears, the elastic stop blocks 3-5 on two sides move towards each other for restoring, and when the circular arc-shaped guide surface 7-7 is separated from the locking surface 3-9, the elastic stop blocks 3-5 restore to the original state, so that the card discharging baffle plate 3-1 is pressed on the third card discharging opening 4, and the third card discharging opening 4 is closed. In this process, if the elastic stoppers 3-5 on both sides clamp the card discharging shutter 3-1 so that the card discharging shutter 3-1 cannot move laterally, this may cause the third card discharging opening 4 of the second card case 1C to be unable to close. The inclined surface 3-11 well solves the problem, when the elastic stop blocks 3-5 at two sides clamp the card discharging baffle 3-1, as the inclined surface 3-11 inclines downwards and outwards, the elastic stop blocks 3-5 at two sides generate a horizontal component force on the card discharging baffle 3-1, so that the elastic stop blocks 3-5 continue to move transversely, and the third card discharging opening 4 is closed.

The foregoing is illustrative of the present invention and is not to be construed as limiting thereof, but rather as various changes, modifications, substitutions, combinations, and simplifications which may be made therein without departing from the spirit and principles of the invention are intended to be included within the scope of the invention.
