Description

The present invention relates to devices for reading, sorting and collecting contactless ("proximity") access cards. It can be used in access control and management systems (ACS) as a card reader that reads a contactless access card, transmits read information to an ACS, receives classification information about a card from an ACS (for example, “card pass is not allowed”, “permanent employee card” ”,“ Temporary visitor’s card ”and performs either returning the card or receiving it in the store with the possible issuing of a command to a control device, such as a turnstile, to allow passage.

A device for processing contactless smart cards is known, which includes a receiver and a connected smart card drive. The drive has a cavity for collecting and storing smart cards and an external pocket for returning the card to the user, and the receiver includes a reader and control unit, as well as a card receiving and sorting unit. The latter includes a stepper motor and a sorting pocket connected to its rotor, which provides reception and placement of a card for reading it using the specified reading and control unit with the possibility of its subsequent storage for storage in a closed storage cavity or for issuing to the user through an external storage pocket, depending from the results of reading information from the card (patent RU 2306608 of 03.24.2006, IPC G07C 9/02). The disadvantage of this device is the design complexity: the sorting pocket has an inlet, an outlet, and angular movement under the control of a stepper motor is used between three positions, in the first of which the sorting pocket allows the card to be received through the inlet and placed for reading, in the second - the direction of the card through the outlet in the outer pocket of the drive and in the third - the direction of the card through the outlet in the closed cavity of the drive.

The closest analogue to the present invention is a proximity card collection device, which consists of a housing, on the front panel of which an LED indicator of permission / prohibition of passage is installed; In the upper part of the body are installed: proximity card reader, receiving and pushing mechanisms with solenoids, control board. On the control board are located: a two-line digital indicator of the number of cards collected and the code of the detected error. A card collection container is located inside the rack. The rack is equipped with optical sensors for filling the container at 75% and 100%. The proximity card reader is located in the receiving mechanism, it provides the reading of the card code and its transfer to the control board of the USPK, which then transfers the code to the ACS only if the card is completely inserted in the receiving mechanism. The receiving mechanism ensures the fixing of the card for reading the code, placing the card in the container, blocking the receiving hole of the rack for the time a person passes through the turnstile, as well as in cases where further reception of cards is impossible. The receiving mechanism is equipped with two optical sensors located in the upper and lower parts of the receiving tray, which allows to determine the presence and movement of the card in the receiving tray. The ejector mechanism allows the card to be pulled out of the receiving mechanism so that it is convenient to take it by hand. The ejector mechanism also ensures the removal of foreign objects from the receiving mechanism (http://www.elics.ru/).

The disadvantage of this device is that the operation of the receiving and pushing mechanisms is carried out from two solenoids, which leads to the complication and cost of the device.

The technical result of the invention consists in the application of a more technologically advanced and reliable card reader mechanism, in which both the card control and the card reader curtain are controlled by one engine, which increases the reliability of the card reader and reduces the cost of its manufacture.

This result is achieved due to the fact that the card reader contains a housing with a door, a card reader mechanism, a card reader, a card collection container, sensors that determine its filling by 75% and 100%, and a card reader controller.

In accordance with the invention, the card reader mechanism is made in the form of a DC motor with a two-arm lever mounted on its axis, the first shoulder of which controls the mechanism curtain through the shutter finishing device, and the second shoulder feeds the card into the card collection container and returns the card to its holder.

In addition, the shutter lapping device consists of a beam and a spring, while the kinematic connection of the first shoulder of the two shoulders of the lever with the beam is made with the possibility of disengaging from the beam at a small angle of rotation of 5-10 ° of the first shoulder in a clockwise or counterclockwise direction from the middle position, and refinement of the rocker to extreme positions is carried out using a spring.

In addition, the mechanism is equipped with a curtain position sensor and two card position sensors in the card reader.

The card reader device is illustrated by drawings:

figure 1 presents a General view of the card reader;

figure 2 is a top view of the mechanism of the card reader;

figure 3 is a view of the mechanism of the card reader on the right in the position of "check card";

figure 4 is a view of the mechanism of the card reader on the left in the position of "check card";

figure 5 is a view of the mechanism of the card reader on the left in the initial position and in the position "return the card to the owner";

figure 6 is a view of the mechanism of the card reader on the left in the position "card pass into the container."

The card reader comprises a housing 1 with a door 2, a card collection container 3, a card reader mechanism 4, a card reader 5, sensors 6 and 7, which determine the filling of the container 3 by 75% and 100%, the card reader controller 8. The door 2 of the card reader is locked 9 (Fig. 1).

The mechanism 4 of the card reader (FIGS. 2-6) consists of a receiving window 10 for cards, a DC 12 V electric motor (motor) 11, with a rotation axis of which the two-arm lever 12 is rigidly connected, for example, with a screw 13 (see FIG. 4). The engine 11 is mounted on the housing 14 of the mechanism with 4 screws 15.

The lever 12 has two shoulders (see Figs. 4-6) - the lower arm 16 and the upper arm 17. The lower arm 16 has a bent end (see Fig. 4, view DG), which serves as a support for the card 18 (see Fig. 5) when it is lowered into the receiving window 10; the bent end of the lower shoulder moves in the slot 19 made in the housing 14 of the mechanism 4, while turning the lever clockwise, the card rises (returns to the owner), and when you turn the lever counterclockwise, the card falls into the container 3 for collecting cards (see figure 4).

The upper shoulder 17 with its bent end is connected with the beam 20 with the possibility of rotation on the axis 21, fixedly mounted on the housing 14 of the mechanism 4 (see figure 4 view BB). The engagement of the bent end of the upper arm 17 with the rocker 20 occurs in the hole 22 of the rocker arm 20 at a small angle of 5-10 ° rotation of the upper arm 17 clockwise or counterclockwise from the middle position. With a pin 23 fixedly mounted on the rocker arm 20, a tension spring 24 is connected, the second end of which is fixed on a pin 25 fixedly mounted on the housing 14 of the mechanism 4. The purpose of the spring 24 is to quickly adjust the rocker arm 20, after disengaging with the upper arm 17, to the extreme positions that correspond to the stop of the pin 26, fixedly mounted on the beam 20, to the edges of the slot 27 made in the housing 14 of the mechanism 4. The pin 26 is connected with the shutter of the mechanism 28, which can move horizontally and rectilinearly along the guide, Making a body in the housing 14 of the mechanism 4. In the position of the shutter 28 from the middle (see FIG. 4) to the rightmost window 10 for receiving cards does not overlap the shutter 28 and the card can be inserted into the card slot. In the leftmost position of the shutter 28 (see FIG. 6) and at some distance from the leftmost shutter, the card receiving window 10 is closed by the shutter 28 and the card cannot be inserted into the card reader. In addition, in the extreme right position, the shutter of the mechanism 28 overlaps the beam of the optoelectronic sensor 29, which serves as a command to stop the engine 11.

Mechanism 4 also has two card position sensors - 30 and 31, which are used by the controller to detect events such as “the card is inserted”, “the card is in the“ card check ”position,“ the card is discarded into the container ”(see Fig. 5 , 6).

The mechanism 4 has a light indication of the state (“ready to accept the card”, “passage allowed”, “pick up the card”), consisting of transparent glass 32 and two-color (green and red colors) LEDs 33 (Fig. 4).

The operation of the card reader is as follows.

The initial position is shown in figure 5: the shutter 28 is in the extreme right position, overlaps the sensor 29 and does not close the receiving window 10 for cards.

If a card 18 is inserted in the card reader, then its presence is detected by the sensor 30, and the engine 11 rotates the lever 12 with the arms 16 and 17 counterclockwise until the card, lowering along with the arm 16, overlaps the sensor 31; in this position, the engine stops, and the card reader 5 reads the information from the card and transfers it to the ACS - this position is shown in figure 4. Simultaneously with the rotation of the shoulder 16 rotates and the shoulder 17; during rotation, the shoulder 17 enters the hole 22 of the rocker arm 20 and rotates the rocker arm 20 to the position shown in figure 4. In this case, the rocker 20 with its pin 26 moves the curtain 28 to the left, and it closes the receiving window 10 for cards so that it is impossible to insert a new card.

Then, depending on the results of the reconciliation of the card in the card reader with the database, the ACS sends a signal to the card receiver either to return the card if the card is permanent or invalid, or to receive the card in container 3 for collecting cards if the card is valid and temporary (one-time) .

When the card 18 is returned to its owner, the engine 11 begins to rotate the lever 12 with the arms 16 and 17 clockwise, the arm 16 pushes the card up, and the arm 17 during rotation goes into the hole 22 of the rocker arm 20 and turns the rocker arm 20 until the arm 17 will not come out of engagement with the hole 22, then the beam 20 is brought by the spring 24 to the position shown in figure 5. In this case, the rocker 20 with its pin 26 moves the shutter 28 to the right so that it overlaps the sensor 29; engine 11 stops (see FIG. 5). The cardholder is given a certain time (4 s-5 s) to pick up the card. If the card belongs to a regular employee, then at the same time as the card is returned, a signal is sent to open a controlled blocking device (turnstile, gate, etc.).

When receiving the card 18 into the card collection container 3, the engine 11 starts to rotate the lever 12 with the arms 16 and 17 counterclockwise, the arm 16 stops blocking the path of the card and the card falls into the card collecting compartment 3, and the arm 17 rotates the rocker 20 during rotation from the middle position to the left by 5-10 °, after which it disengages from the hole 22 of the rocker arm 20, and the spring 24 brings the rocker arm 20 to the position shown in Fig.6. In this case, the rocker 20 with its pin 26 moves the shutter 28 even more to the left, and it continues to overlap the receiving window 10 for cards so that it is impossible to insert a new card. The card reader controller 8, analyzing the signals from the sensors 30 and 31, determines the moment when the card fell into the card collection container 3 and instructs the engine 11 to turn the lever 12 clockwise to the initial position shown in FIG. 5. Simultaneously with the reception of the card 18, a signal is sent to the container 3 for collecting cards to open a controlled blocking device, such as a turnstile.
