Description

The invention relates to devices used in security systems for storing and issuing items subject to special preservation, for example keys, storage media, jewelry, and can be used in security systems of facilities with high security requirements, for example, nuclear weapons complex enterprises, nuclear power plants etc.

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

The holder 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 a solution 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, which negatively affects the reliability of the device, and also increases the complexity of manufacturing.

It is also known a device for storing and issuing items (RF patent No. 2058591, G07C 9/00, G07F 11/48, publ. 04/20/1996), which contains a control unit, a housing with cells, each of which has an electromagnet, a storage container objects installed in the cell with the possibility of fixation, position sensors (sensors of the presence of the container).

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 set 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 its lack of reliability, caused by the presence of parasitic friction forces at the point of kinematic contact of the hook of the retaining strap with the container at the moment the magnet is triggered or jamming of the hook when the container is locked, which requires large working currents of the electromagnet, weighting of the strap and gradually leads to wear of the contacting elements; the possibility of direct physical impact and damage to the retaining strap by the container during unauthorized attachment; as well as opening all in a row of containers with manual opening and insecurity of the device when the container is tilted.

Also known is a device for storing and dispensing items (RF patent No. 2111132, G07C 9/00, publ. 10.11.1999), which contains a control unit, a housing with cells, each of which has a container for storing items, position sensors (presence sensors container), an electromagnet, a spring-loaded rod (ejector element), 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.

A protrusion is made in each container on the rear inner end surface, and the container retaining plate is configured to place its free end under the protrusion and exit from the protrusion by pressing on the container pushed by one end of the spring-loaded rod installed in each cell with the formation of a gap greater the length of the protrusion 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 control circuit to carcass of an electromagnet.

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 gap 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 electromagnet coil circuit, which allows it to perform the function of controlling the electromagnet at the hardware level (in case of unauthorized container insertion). 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.

This device provides reliable operation with a minimum of elements and kinematic relationships under various operating modes (storage, authorized removal and authorized attachment of containers) and ease of use with the device.

However, if the container is absent, 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 impossibility of fixing the container in the cell during unauthorized attachment, but does not prevent the container from being inserted into the cell, which also affects the reliability of the device.

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

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.

A device for storing and issuing items (RF patent No. 2366789, E05G 1/00, G07F 11/60, publ. 09/10/2009), which contains a housing with cells, each of which has a container for storing items, a control unit, sensors position (container presence sensors) connected to the control unit, an electromagnet and an LED indicator connected to the control unit, an element that controls the blocking and unlocking of the cell (blocker), the container is installed in the cell with the possibility of fixing and interaction with the rear wall with spring-loaded rod (ejector element), each cell is equipped with a spring-loaded shutter, blocking the cell in the "without container" position, a button for removing the container, a spring-loaded gripping lever, a spring-loaded swing lever with a pin (with a protruding element), configured to accommodate a pin (protruding element) in the hole in the upper wall of the container body in the "storage" position. This technical solution is selected as a prototype of the invention.

In this device, each cell is equipped with a stop, the armature of the electromagnet is a strap, the strap is installed with the ability to interact with the curtain in one end without a container, the other with a stop, and in the unlock position, respectively, with the gripping lever and the swing lever, the other the end of the spring-loaded stem is connected to the corresponding position sensor.

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.

Reliability in the use of this device is ensured by the impossibility of unauthorized attachment of the container to the cell, and not only its fixation in the cell, since this reduces the number of contact closures of the sensor and an additional decrease in its life, and the sensor contacts switch circuits 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. Ease of use is that there is no need to use special tools to remove containers in an emergency, since a lock device is used that is common to all cells and is driven by a key.

The disadvantages of this device include: the need to form niches under the cells into which the curtains should move, which complicates the design and increases the cost of the device; the location of the axis of the spring-loaded swing levers behind the cell, which increases the depth of the device; the location of the sensors behind the cells, which also increases the depth of the device; the interaction of containers with sensors through a spring-loaded rod, which increases the depth and leads to structural complication and cost of the device; the presence of individual axes for each cell in the suspension of the armature of an electromagnet, made in the form of a spring-loaded bar, and an exciting lever, which complicates and increases the cost of the device. This spring-loaded bar is the element that controls the locking and unlocking of the cell (lock) for the curtain, and, in addition, the link to convert the movement of the gripping lever into the rotational movement of the spring-loaded swing arm with a pin (with a protruding element). To implement these functions, the spring-loaded bar requires a complex suspension, which also complicates and increases the cost of the device.

Thus, the disadvantages of the above device are a large number of elements, the features of their mutual arrangement and interaction, which leads to a decrease in reliability, as well as the high complexity and high cost of manufacturing, and, therefore, makes the device too expensive for widespread implementation. In addition, the device has significant dimensions and weight.

The problem to which the invention is directed is to create a device for storing and dispensing items for use in security systems of objects with high security requirements.

The technical result of the claimed invention is to reduce the complexity of manufacturing a device for storing and dispensing items, increasing its reliability, as well as reducing its size and weight.

To achieve the specified technical result in a known device for storing and dispensing items containing a housing with cells, each of which has a container for storing items, a control unit, container presence sensors connected to the control unit, an electromagnet and an LED indicator connected to the control unit , a blocker, while the container is installed in the cell with the possibility of fixation and interaction with the rear part with the ejector element, and each cell is equipped with a spring-loaded shutter, tearing the cell in the "without container" position, with a button for removing the container, a spring-loaded gripping lever, a spring-loaded swing arm with a protruding element, configured to place the protruding element in the hole in the upper wall of the container in the "storage" position, according to the invention, the control unit includes a controller and an input-output module, the input-output module is made in the form of a printed circuit board and is located above the cells along the rear wall of the housing, each electromagnet and LED The indicator is placed on a printed circuit board mounted on the side wall of the cell, each printed circuit board mounted on the side wall of the cell is made with holes, each electromagnet, container presence sensor and LED indicator are connected to the input-output module by means of printed conductors made on the printed circuit board, fixed on the side wall of the cell, each electromagnet is equipped with a rod connected to the blocker, each blocker is freely mounted on a shaft passing over the entire row of cells, above each cell on the pusher is fixed to the shaft, made to interact with the lock, each pushing element is made in the form of a spring, each spring-loaded curtain is movable into the space above the cell, each spring-loaded swing arm with a protruding element is equipped with a link made to engage with a spring-loaded gripping lever equipped with a button for removing the container, the spring-loaded gripping lever and the spring-loaded curtain are located on the same axis, spring-loaded th rotary levers with protruding elements are located on a common axis located above the cells, the shaft and axes are located in the holes of the printed circuit boards mounted on the side walls of the cells.

The container presence sensor can be made in the form of a micro switch equipped with a lever.

The container presence sensor can be made in the form of two elastic plates located on a printed circuit board.

The container presence sensor can be made in the form of a magnetically controlled contact interacting with a magnet installed in the container wall.

The shaft can be made with a bend at the end, forming a lever.

The link can be made in the form of a rectangle of wire.

The link can be made in the form of a thin plate equipped at its free end with an element for engaging with a gripping lever.

The technical result is achieved due to the constructive implementation, the relative position and interaction of the constituent elements.

The location of the input-output module, made in the form of a printed circuit board, above the cells along the rear wall of the housing allows to reduce the dimensions of the device.

The use of a printed circuit board for placing an electromagnet and an LED indicator leads to constructive simplification and reduction in the number of structural elements of the device for storing and dispensing items, since no special elements are required for their fastening and electrical connection with the input-output module.

The holes in the printed circuit board mounted on the side wall of the cell, fixes the shaft and axes passing through a series of cells, which leads to structural simplification and reduction in the number of structural elements, since no special elements are required to fix the shaft and axes.

The connection of electromagnets, container presence sensors and LED indicators to the input-output module by means of printed conductors made on a printed circuit board reduces the volume of wired installation, which reduces the complexity and increases reliability (errors in wired installation are excluded, the possibility of damage to conductive elements during installation and operation is minimal )

Each spring-loaded swing arm with a protruding element is provided with a link made to engage with the spring-loaded gripping lever. The separation of the functions of the backstage and the blocker made it possible to avoid the use of complex suspensions: the backstop is attached directly to the spring-loaded swing arm, and the blocker is freely mounted on a shaft passing over the entire row of cells.

The implementation of the ejection element in the form of a spring directly interacting with the container reduces the depth of the device, the number of elements in the structure and the number of kinematic bonds, which reduces the complexity of manufacturing and improves the reliability of the structure.

The spring-loaded curtain is made with the possibility of moving into the space above the cells, which eliminates the need to manufacture a bottom of complex shape with niches for curtains, that is, it reduces the complexity and cost, and also reduces the size of the device for storing and dispensing items.

The use of one axis for a spring-loaded gripping lever and a spring-loaded shutter reduces the total number of axles, which affects the complexity and cost of manufacturing, and also reduces the weight of the device.

Spring-loaded swivel arms with protruding elements are located on a common axis located above the cells. Such an arrangement of the axis reduces the depth of the device.

The container presence sensor can be made in the form of a micro switch equipped with a lever. When installing the container in the cell, the back of the container is pressed by the microswitch lever. Using a microswitch as a purchased product simplifies the complexity of manufacturing. Direct interaction of the container with the sensor reduces the number of structural elements, which increases the reliability of the device.

The container presence sensor can be made in the form of two elastic plates located on the printed circuit board of the input-output module or on a printed circuit board mounted on the side wall of the cell. This sensor design is easy to manufacture. In this embodiment, the direct interaction of the container with the sensor also reduces the number of structural elements, which increases the reliability of the device.

The container presence sensor can be made in the form of a magnetically controlled contact interacting with a magnet installed in the container wall. The magnetically controlled contact is more reliable, as it is sealed and designed to work in the field of low currents.

The shaft can be made with a bend at the end, forming a lever needed to rotate the shaft using a locking device. Such a manufacture of an element for rotating the shaft (lever) is a simple technological operation and significantly reduces the complexity of its manufacture.

The link can be made in the form of a rectangle of wire. This embodiment simplifies the manufacture of this element, and also requires a minimum amount of material, which significantly reduces the cost and weight of this element.

The link can be made in the form of a thin plate equipped at its free end with an element for engagement with a spring-loaded gripping lever. The backstage made in this way does not require a large consumption of material, which leads to a reduction in the cost and weight of the backstage.

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 were not identified in technical solutions for a similar purpose. On this basis, we can conclude that the claimed invention meets the condition of "inventive step".

The invention is illustrated by drawings:

in FIG. 1 shows a general view of a device for storing and dispensing items;

in FIG. 2 shows an image of a cell with a container installed;

in FIG. 3 shows an image of a cell with the spring-loaded pivoting and spring-loaded gripping levers rotated before the container is pushed out by the ejector element;

in FIG. 4 shows an image of a cell without a container.

A device for storing and dispensing items (Fig. 1) consists of a housing 1 with a locking device (not shown in the drawing) with a lock 2 and blocks 3 installed in it with rows of cells 4 for installing containers 5 (see Fig. 2). Each block 3 contains sixteen cells 4. In FIG. 2 shows a cell 4 with an installed container 5 and related structural elements. Each cell 4 is equipped with a spring-loaded pivoting lever 6 with a protruding element 7, configured to accommodate the protruding element 7 in the hole 8 in the upper wall of the container 5. To push the container 5 out of the cell 4, a spring 9 is used. An input-output module 10 is located along the entire block 3 The control of the presence of the container 5 in the cell 4 is carried out using the sensor 11 of the presence of the container. All spring-loaded swing levers 6 are located on a common axis 12. Each spring-loaded swing arm 6 is provided with a link 13. The electromagnet 14 is connected by a rod 15 to the lock 16. The lock 16 can rotate around the axis, which is the shaft 17. Above each cell 4 on the shaft 17 is mounted a pusher 18 with the possibility of interaction with the lock 16. The lock 16 is equipped with a strap 19 for moving the wings 13 up and down. A spring-loaded gripping lever 20 can interact with the wings 13. A LED indicator 21 is displayed on the front panel in each cell 4. The LED indicator 21 is used to display information on unlocking the cell 4 and events in the security alarm system. The LED indicator 21, the electromagnet 14 and the container presence sensor 11 are mounted on a printed circuit board 22 mounted on the side wall 23 of the cell 4. The shutter 24 prevents unauthorized installation of the container 5 in the cell 4 or the ingress of foreign objects. The spring-loaded gripping lever 20 is provided with a button 25 for removing the container 5. The shutter 24 and the spring-loaded gripping lever 20 are mounted on a common axis 26 passing through the entire unit 3. Holes are made in each printed circuit board 22 mounted on the side wall 23 of the cell 4 (in the drawing not shown) for axles 12, 26 and shaft 17.

The end of the shaft 17, extending beyond the block of 3 cells 4, is bent at an angle of 90 ° and serves as a lever for turning the shaft 17. The lever is moved by a bar with cutouts at the level of each lever (not shown in the drawing). The bar is located vertically and passes by all the blocks 3. The bar is moved vertically by a cam mechanism (not shown in the drawing) associated with the lock 2 located on the front wall of the housing 1.

The control unit (not shown) is a part of the device for storing and dispensing items and provides control of electromagnets 14 and LED indicators 21 by commands from a computer, as well as receiving signals from sensors 11 for the presence of containers. The control unit consists of a controller (not shown in the drawing) and input / output modules 10. The controller is common to the entire device, input / output modules 10 are contained in each block 3 with cells 4.

The controller is located at the side wall of the housing 1. The placement of the controller at the side wall minimizes the length of the cables connecting the controller to the input-output modules 10, and also helps to reduce the size of the device for storing and dispensing items.

The shape of the lock 16, the spring-loaded swing arm 6, the spring-loaded gripping arm 20 and the shutter 24 allows them to be performed without the use of expensive milling operations (for example, by laser cutting and bending), which reduces the complexity and cost of manufacturing.

The link 13 is adapted to engage the spring-loaded gripping arm 20. In this embodiment, the link 13 is made in the form of a rectangle of wire. The link 13 can be made in the form of a thin plate equipped at its free end with an element for engagement with a spring-loaded gripping lever 20 (not shown in the drawing). The element for engagement can be made in the form of a slot, groove, recess, bending, etc.

As the container availability sensor 11, a micro switch equipped with a lever is used, which is a purchased product. The triggering of the sensor 11 when installing the container 5 in the cell 4 is carried out as a result of pressing the back of the container 5 on the lever of the micro switch. The use of a microswitch as a purchased product may be preferred in the manufacture of small batches of devices.

The container presence sensor 11 can be made in the form of two elastic plates arranged parallel to each other (not shown in the drawing) and mounted on a printed circuit board of the input-output module 10 or on a printed circuit board 22 fixed on the side wall 23 of the cell 4, and closed between by itself when installing the container 5 in the cell 4 as a result of pressing the plate of the sensor 11 with the back of the container 5.

The sensor 11 for the presence of the container can be made in the form of a magnetically controlled contact interacting with a magnet installed, in the case of using a magnetically controlled contact, in the wall of the container 5.

A device for storing and dispensing items runs on a computer.

The device operates as follows.

The process for removing the case is illustrated in FIG. 2-4.

A device for storing and dispensing items works 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 attach or remove the container. The control unit provides control of the electromagnets 14 and LEDs 21 by commands from the computer, as well as the reception of signals from sensors 11 for the presence of containers.

To remove the container 5 from cell 4, it is necessary to turn the spring-loaded swing arm 6 clockwise so that the protruding element 7 emerges from the hole 8 in the container 5. To do this, pull the link 13 to the right. If, after identifying the user with the biometric identification device, the control computer has established the user’s right to receive the container, he will give a command to the controller. The controller through the I / O module 10 will supply voltage pulses to the LED indicator 21 and a constant voltage to the electromagnet 14 of the corresponding cell 4. The flashes of the LED indicator 21 will help the user find the desired cell 4. The electromagnet 14 will turn the lock 16 clockwise through the rod 15. The bar 19 of the lock 16 will fall down (see Fig. 3). Now, when you press top down on the button 25, the upper edge of the spring-loaded gripping lever 20 will move the link 13 to the right. The spring-loaded swing arm 6 will rotate clockwise, and the protruding element 7 will exit the hole 8. The voltage from the electromagnet 14 will be removed by the controller after removing the container 5 by the signal of the container presence sensor 11, or after a predetermined time interval. In the event of an automation failure, it is possible to turn the locks 16 of all the cells 4 in the block 3 by turning the shaft 17, due to the presence of pushers 18 in each cell 4, mounted on the shaft 17. The shaft 17 is rotated using a locking device 2.

After removing the container 5, the shutter 24 will go down (see Fig. 4), the lock 16 will return to its original position and will not allow the shutter 24 to move into the space above the cell 4. In this state, the installation of the container 5 in the cell 4 is impossible.

To install the container 5 in cell 4, the user must be identified using a biometric identification device. If, after identifying the user, the control computer has established the user’s right to attach the container, he will issue a command to the controller. The controller through the I / O module 10 will supply voltage pulses to the LED indicator 21 and a constant voltage to the electromagnet 14 of the corresponding cell 4. The flashes of the LED indicator 21 will help the user find the desired cell 4. The electromagnet 14 will turn the lock 16 clockwise through the rod 15. Now the blocker 16 will not impede the movement of the shutter 24 in the space above the cell. When you press the shutter 24 with the back of the container 5, it will move into the space above the cell 4 and will not prevent the container 5 from being inserted into the cell 4. When the container 5 is advanced (see Fig. 2) into the cell 4, the spring-loaded swing arm 6 is rotated so that the protruding the element 7 slides over the surface of the container 5, and then enters the hole 8. The installation of the container 5 in the cell 4 is possible for a time while the electromagnet 14 is energized. The voltage will be removed by the controller by a signal from the container availability sensor 11 or after a predetermined time interval.

In case of automation failure, the locks 16 in all cells can be rotated by turning the shaft 17 through the pushers 18 fixed on it in each cell 4. The shaft 17 is rotated using a locking device 2.

The device has no fundamental restrictions on the number of cells and the type of control device. The manufactured prototype device consists of two rows of cells. Each row contains 16 cells for installing containers.

Interface RS-485 Maximum distance from the control station when using the RS-485 interface 1.2 km Supply voltage 10-15 B Maximum power consumption (on 1 row of cells) 2 watts

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