Description

The invention relates to devices used in security systems for storage in containers of items subject to special preservation, for example, keys, passes, storage media, money, jewelry, and can be used in security systems in production, administrative services, banks, postal departments.

A device for storing objects is known (patent SU No. 1827035, class G11B 23/03, publication date 07/07/1993) containing a control unit, an electromagnet, a housing in which a container (holder) is mounted with the possibility of fixation.

The container has a guide groove in the form of a wedge and a wedge-shaped groove, a latch with a protrusion fixed in the housing and, under the action of a spring, a fixing container in the housing made with a groove in which a slider with a wedge-shaped end surface with an opening angle equal to or greater than the angle of the wedge of the guide is installed container grooves. The slider interacts with the container with its end surface.

The disadvantages of the device are its complexity (wedge-shaped grooves and surfaces) and the redundancy of kinematic connections and elements.

Also known is a device for storing and dispensing items (patent RU No. 2058591, class G07C 9/00, G07F 11/48, publication date 04/20/1996), which contains a control unit, position sensors, a housing with cells, each of which is installed an electromagnet, the anchor of which is a holding bar, a container for storing objects, which is installed in the cell with the possibility of fixation.

The containers are installed in the cells with the possibility of folding them to the stop under the action of gravity. Each container is locked in an upright position by a holding bar, which contacts as an anchor to the core of the electromagnet, has a hook from the holding end, and the opposite end, having a groove, is freely mounted on the fixed part of the magnetic circuit and placed in a groove mounted in the comb housing, which can axially rotate up to the emphasis in the cores of the electromagnets of a number of retaining bars for lifting them up in case of emergency.

The disadvantages of the device are: the presence of parasitic friction at the point of kinematic contact of the hook of the retaining strap with the container at the time the electromagnet is triggered or the hook is jammed when the container is locked, which requires large working currents of the electromagnet, the weight of the strap and gradually leads to wear of the contacting elements; the possibility of direct physical impact and damage to the holding strap by the container during unauthorized investment; as well as opening all in a row of containers with manual opening and insecurity of the device when the container is tilted.

The closest in technical essence to the claimed device is a device for storing and dispensing items (patent RU No. 2141132, class G07C 9/00, publication date 10/11/1999), which contains a control unit, position sensors, a housing with cells, in each of which has a container for storing items, an electromagnet whose anchor is a strap, and a spring-loaded rod, the container is mounted in the cell with the possibility of fixation and interacts with the rear wall with one end of the spring-loaded rod, the other end of which interacts the corresponding encoder.

A protrusion of length z is made in each container on the rear inner end surface, and the retaining strip of the container is configured to place its free end under the protrusion and exit from the protrusion when the container is pushed by one end of the spring-loaded rod installed in each cell to form the gap d is greater than the length of the protrusion z between the rear wall of the container and the inner end wall of the cell, while the other end of the rod is connected via a spring to a position sensor included in the chain ION solenoid coil.

The protrusion on the rear inner end surface is necessary in order to prevent the retaining bar from rising upward when the control voltage is applied to the electromagnet.

A spring-loaded stem is necessary to provide a clearance d between the rear wall of the container and the inner wall of the cell, while ensuring that the retaining bar is under the protrusion in storage mode and to push the container out of the cell in the mode of authorized removal or unauthorized insertion.

The position sensor contains a switching contact and is necessary to determine the location of the container. The switching contact is closed when the container is in the cell, and open when it is absent, while the switching contact is included in the coil of the electromagnet, which allows it to perform the function of controlling the electromagnet at the hardware level (in case of unauthorized insertion of the container). Attaching a container by mistake not to its cell or without entering an identification code will lead to the preliminary inclusion of the electromagnet and the raising of the retaining bar. When the container is pushed out, the switching contact will open, and the holding bar will lower only after the container has passed the capture zone.

In this device, the task of increasing the reliability of work with a minimum of elements and kinematic connections at various operating modes (storage, authorized removal and authorized attachment of containers) and the convenience of working with the device were solved.

However, when the container is missing, the cell becomes unprotected from foreign objects, unauthorized actions and direct access to the electromagnet anchor, which does not provide high reliability of the device. The device provides the ability to fix the container in the cell during unauthorized attachment, but does not prevent the container from being inserted into the cell.

A disadvantage should be considered as a way to prevent the container from fixing in the cell (supplying power to the electromagnet), since the sensor contacts switch the circuit with an inductive load, which is an electromagnet, which leads to a decrease in the sensor resource reduce device reliability.

In addition, in emergency situations, the removal of containers requires a special tool that needs to act on the ends of the retaining bars through the holes in the cell housings, which creates inconvenience, and the presence of such holes reduces the security of the device from unauthorized actions.

The task of the invention is to increase the reliability and ease of operation.

The problem is solved in that in a device for storing and dispensing items containing a control unit, position sensors, a housing with cells, each of which has a container for storing items, an electromagnet whose anchor is a strap, and a spring-loaded rod, the container is installed in the cell with the possibility of fixation and interacts with the rear wall with one end

a spring-loaded rod, the other end of which interacts with a corresponding position sensor, according to the invention, each cell is equipped with a stop and a spring-loaded shutter covering the cell in the “without container” position, in addition, each cell is equipped with a spring-loaded gripping lever connected to the pusher and a spring-loaded swing lever with a pin made with the possibility of placing the pin in the hole in the upper wall of the container body in the "storage" position, the bar is installed with the possibility in the position " ithout container "interact at one end with a shutter, the second abutment c, and set to" unlatch "- respectively, with exciting lever and the pivot arm, wherein each sensor is connected to the control unit.

To enable horizontal movement of the bar and its interaction in the “without container” position with one end with a shutter, the other with a stop, and when unlocked, respectively, with a gripping lever and a rotary lever, each cell is equipped with a spring-loaded suspension, one end of which is fixed to cell body, and at the other end is fixed strap.

For ease of use, the device for storing and dispensing items is equipped with a locking device containing a pressure lever, made in the form of a plate interacting with the slats of all cells.

Compared with the prototype, an increase in reliability is achieved by a constructive solution in which it is impossible to unauthorizedly insert the container into the cell, and not just fix it in the cell, therefore, the number of contact closures of the sensor and an additional decrease in its life are reduced, and the sensor contacts commute the circuit with a high-resistance active load. It excludes the possibility of foreign objects getting into the cells, which can cause damage or disruption of the mechanisms. There are also no openings in the cell housings for removing containers in emergency situations, which reduce the security of the device from unauthorized actions. Convenience lies in the fact that no special tools are required to remove containers in an emergency, but a lock device is used that is common to all cells and is powered by a key.

The presence in the claimed invention features that distinguish it from the prototype, allows us to consider it appropriate to the condition of "Novelty."

New features “each cell is equipped with a stop and a spring-loaded shutter that overlaps the cell in the“ no container ”position; in addition, each cell is equipped with a spring-loaded gripping lever associated with a pusher and a spring-loaded swing arm with a pin configured to accommodate the pin in the hole in the upper wall the container body in the “storage” position, the bar is installed with the ability to interact in the “without container” position with one end with the shutter, the other with the stop, and in the “unlock” position, with accordingly, with a gripping lever and a rotary lever, and each sensor is connected to a control unit ”not found in technical solutions for a similar purpose. On this basis, we can conclude that the claimed invention meets the condition of "Inventive step".

A device for storing and issuing items consists of a housing 1 with cells 2, in each of which is inserted a container (pencil case) 3 for storing items, such as keys, (figure 1). Each cell 2 (figure 2) contains an electromagnet 4 located above the container 3 with an anchor mounted on a spring suspension 5, made in the form of a spring bar 6, a pusher (button) 7 connected to a gripping spring lever 8, a spring-loaded swing arm 9 with a pin 10 , fixed L-shaped stop 11, pressure lever 12 of the locking device, spring-loaded shutter 13, spring-loaded rod 14, sensor 15 and indicator 16. Electromagnet 4, sensor 15 and LED 16 are connected to the control unit (not shown in the drawings).

Container 3 is a pencil case, having its own system of protection against unauthorized access to objects stored in it. An opening 17 is made in the upper wall of the container 3 (FIG. 3) to enable the container 3 to be fixed in the cell 2 in the “storage” position by inserting a pin 10 located on the lever 9 into this hole. The stop 11 limits the angle of rotation of the lever 9 so that ensured unimpeded installation of the pencil case and its fixation with a pin 10 (figure 3). The shutter 13 is fixed in the base of the housing 1, overlaps the inlet of the cell 2 in the absence of a container 3 (the position "without container") and is fixed by a strap 6 (figure 4). When unlocking the container 3 (the "unlocking" position) (Fig. 2), the bar 6 interacts with the grab arm 8 at one end and with the swing arm 9 at the other end. The bar 6 is fixed at one end of the spring-loaded suspension 5, the other end of which is fixed on an axis on the upper wall of the housing 1. This allows horizontal movement of the strap 6.

For ease of operation (providing the possibility of installing and removing containers in an emergency), the device for storing and dispensing containers has a locking device (not shown) containing a pressure lever 12, made in the form of a plate, interacting, if necessary, with strips 6 of the entire row of cells 2.

The device operates with a system containing a biometric user identification device and a computer as a control device.

The computer receives information about the user's identity from the identification device and checks the user’s rights to insert / remove containers 3. The control unit is part of the device and provides control of the electromagnets 4 and LEDs 16 by commands from the computer, as well as the reception of signals from sensors 15 of the position of the containers 3 .

The device operates in three modes: “authorized container attachment”, “container storage”, “authorized container removal”.

In the absence of a container 3, the “no container” position (FIG. 4), the electromagnet 4 is de-energized, and the strip 6 is located so that it blocks the curtain 13 closing the inlet of the cell 2: when the curtain 13 is pressed, it interacts with one end of the strip 6, the other end of which interacts with the stop 11, thereby preventing the curtain 13 from turning and opening the inlet of the cell 2.

Authorized Container Attachment mode

To embed container 3 into storage in cell 2, the user must first be identified so that the control system can verify his rights to embed container 3. If the system has established the right to embed container 3, then voltage is applied from the control unit to the electromagnet 4 of the corresponding cell 2 and LED indicator 16 located above this cell 2 and displayed on the front panel of housing 1. LED indicator 16 starts flashing, helping the user find cell 2 where he is allowed to put the container p 3. Under the action of the voltage applied to the electromagnet 4, the strip 6 is pulled towards it and releases the shutter 13. During the time when the electromagnet 4 is energized, it is possible to install the container 3 in the cell 2. Thanks to the bevel on the pin 10, the container 3 is freely moved to the end of cell 2. At the moment of alignment of the hole 17 with the pin 10, the lever 9 rotates under the action of its spring, the pin 10 enters the hole 17 and fixes the container 3 in the cell 2 (figure 3).

At the moment when the container 3 is inserted into the cell 2, it presses on one end of the rod 14, moving it. The other end of the rod 14 interacts with the sensor 15 connected to the control unit (not shown). The sensor 15 closes, informing the control unit that the container 3 is installed in the cell 2. The control unit de-energizes the LED indicator 16 and the electromagnet 4. The bar 6 is returned to its original position.

Container Storage Mode

In storage mode, the container 3 is held in the cell 2 by a pin 10. The LED indicator 16 and the electromagnet 4 are de-energized, and the bar 6 is in a position in which one of its ends cannot be caught by the lever 8 to press the other end on the lever 9, turn it and remove the pin 10 from the hole 17 in the upper wall of the container 3 (figure 3).

Authorized container removal mode.

To remove container 3 from cell 2 (as well as for attachment), the user must first be identified so that the control system can verify his rights to remove the container. If the system has established the existence of such a right, then voltage is supplied from the control unit to the electromagnet 4 of the corresponding cell 2 and to the LED indicator 16 located above this cell. LED 16 starts flashing, helping the user find cell 2, from where he is allowed to remove the container 3. Under the action of the voltage applied to the electromagnet 4, the bar 6 is pulled towards it, closing the kinematic chain "pusher 7 - bar 6 - lever 9" (Fig. 2). When you press the pusher 7, displayed on the front panel of the housing 1 above the corresponding cell 2, the lever 8, capturing the end of the strap 6, moves it so that its other end presses on the lever 9, turning it. The pin 10 exits the hole 17 and the container 3 is released. Further, the rod 14, under the action of the spring, pushes the container 3 to a distance that allows it to be gripped by hand. The other end of the rod 14 ceases to interact with the sensor 15, the contacts of the sensor 15 open, informing the control unit about the removal of the container. The control unit de-energizes the LED indicator 16 and the electromagnet 4. After the impact on the pusher 7 has ceased, the lever 8 will return to its original position, freeing the bar 6. The bar 6 returns to its original position. The shutter 13 under the action of the spring, as the container extends from the cell, goes into the initial vertical position, in which it is blocked by the bar 6 (figure 4).

In the event of automation failure in emergency situations and in the absence of power, the container 3 can be inserted into cell 2 or removed from it manually using a key lock device. When you turn the key installed through the window on the front panel of the housing 1, the lever 12, made in the form of a plate, presses all the strips 6 of the row of cells 2 and sets them in the same position as when the electromagnet 4 (not shown) is activated.

The device can be made with several rows of cells 2. In this embodiment, the locking device contains in each row of cells 2 a push lever 12. All levers 12 are rotated simultaneously when the key is rotated.

Compared with known designs, the proposed device has a higher reliability and is more convenient to operate.

The device (automated safe) has no fundamental restrictions on the number of cells and the type of control device. The manufactured prototype device consists of four rows of cells. Each row of cells (pencil case block) contains 16 cells for installing containers (pencil cases). The pencil case block has options for long and short pencil cases.

Interface RS-485 Maximum distance from the station control when using RS-485 interface 1.2 km Supply voltage 10-15 V Maximum power consumption (for 1 block of pencil cases) 2 watts

Thus, the presented information indicates that the claimed invention meets the condition of "Industrial applicability".
