Изобретение относитс к автоматизации складских операций и может быть использовано дл управлени механизированными стеллажами, конвейерами, гаражами и т.п.The invention relates to the automation of warehouse operations and can be used to control mechanized racks, conveyors, garages, etc.

Известно устройство дл автоматического адресовани подвесок механизированного стеллажа, содержащее переключатель подвесок с серводвигателем, мостовую схему с пол ризованным реле в измерительной диагонали, у которой два последовательно соединенных через переключатель подвесок с источником питани , плеча моста, состо щих из четного количества резисторов, зашунтированы последовательным соединением нечетного количества резисторов, образу с ними кольцевую схему с общим количеством резисторов в кольце, соответствующим числу позиций стеллажа 1.A device for automatically addressing mechanized rack racks is known, comprising a suspension switch with a servo motor, a bridge circuit with a polarized relay in a measuring diagonal, in which two axially connected via suspension switch with a power source, the bridge arm, consisting of an even number of resistors, is bypassed by series connection an odd number of resistors, forming with them a ring circuit with a total number of resistors in the ring, corresponding to the number of po shelves 1.

Недостаткам этого устройства вл ютс сложность и низка надежность.The disadvantages of this device are complexity and low reliability.

Наиболее близким по техническому решению к изобретению вл етс устройство дл автоматического управлени перемещением подвесок механизированного стеллажа, содержащее датчик положени подвесок, реле останова и реле выбора направлени , в цепиThe closest in technical solution to the invention is a device for automatic control of the movement of suspensions of a mechanized rack, comprising a sensor for positioning the suspensions, a stop relay and a direction selection relay, in a circuit

питани которых включены соответственно одна группа контактов переключател выбора подвесок, соединенна непосредственно, и друга группа контактов, соединенна через разв зывающие диоды с Г1ереключателем положени подвесок, синхронно св занным с реверсивным электроприводом (2J.the power supply of which includes, respectively, one group of contacts of the suspension selector switch, connected directly, and another group of contacts, connected via decoupling diodes to the G1 switch of the position of the suspensions synchronously connected to the reversing electric drive (2J.

Однако это устройство допускает ошибки в адресовании и недостаточно надежно.However, this device makes errors in addressing and is not reliable enough.

Цель изобретени - повышениеТочности и надежности адресовани .The purpose of the invention is to increase the accuracy and reliability of the address.

Цель достигаетс тем, что устройство снабжено дополнительными разв зывающими диодами, а переключатель выбора подвесок - третьей группой контактов, которые включены последовательно с разв зывающими диодами между реле выбора направлени и переключателем положени подвесок , причем датчик положени подвесок включен последовательно в цепь питани реле останова.The goal is achieved by the fact that the device is equipped with additional isolating diodes, and the suspension selection switch is equipped with a third group of contacts that are connected in series with the isolation diodes between the directional selection switch and the suspension position switch, the suspension position sensor being connected in series to the stop relay power supply circuit.

На чертеже представлена принципиальна схема устройства, выполненна дл восьми подвесок стеллажа.The drawing shows a schematic diagram of the device, made for eight racks of the rack.

Claims

The device comprises a suspension position switch 1, a suspension selection switch 2 with three groups of contacts. decoupling diols 3-24, direction selection relay 25 with closing and disconnecting contacts 25.1 and 25.2, suspension position sensor 26, stopping relay 27 with disconnecting contact 27.1, reversing electric drive 28 and power supply 29. The suspension position switch 1 is kinematically connected to the reversing electric drive 28. The stop relay 27 is connected to the power supply 29, and through the position sensor 26 to the moving contact of the first contact group of the switch 2 for selecting suspensions whose fixed contacts are connected respectively to the fixed contacts of the switch I suspension position. The movable contact of the switch I of the suspension position is connected to the "+ + power source 29. The direction selection relay 25 is connected to the power supply source 29, and through decoupling diodes 3 to 24, respectively, to the second and third groups of contacts of the selector 2 for the suspension, the fixed contacts of which are connected to the Fixed contacts of the suspension position 1 through the isolating diodes 4-23. . The opening and closing contacts 27. and 25.1 form the switching circuit of the reversing electric drive 28 "Back, and contacts 27.1 and 25.2 -" Forward. The device works as follows. If suspension I is located at the unloading position of the rack, and suspension III must be called, which corresponds to the position of the moving contacts of switches I and 2 in the diagram, in this case the directionalization relay 25 is activated in the following circuit: "- power supply 29, diode 3, moving and stationary the contacts of the suspension selection switch 2, the diode 4, the fixed and movable contacts of the suspension position switch 1, " + of the power supply 29. Contact 25.2 of the directional selection relay 25 is opened, and contact 25.1 is closed when the contact 27.1 of the shutdown relay 27 is closed turns on the reversible electric actuator 28 in the Back direction. The rack hangs in the set direction, which provides the shortest path for the desired suspension III to the unloading position. The movement of the rack hangers to one rod corresponds to the movement of the movable contact of the switch 1 of the position of the suspensions from one fixed contact to another. When the suspension III is in the unloading position, the positions of the moving contacts of the switches I and 2 are the same, and the position sensor 26 interacts with the latch. The stop relay 27 is activated and its disconnecting contact 27.1 de-energizes the control circuit of the reversing electric drive 28. If it is necessary to return the suspension 1 to the unloading position, the suspension selection switch 2 is set to the appropriate position. The directional switch 25 in this case does not receive power. The reversible electric actuator 28 is activated along a motion control circuit. Forward disconnecting contact 27.1 of the stop relay 27, disconnecting contact 25.2 of the direction selection relay 25. The suspension of the rack at the unloading position is carried out similarly to that indicated. The proposed device does not require for the adjustment and maintenance of highly qualified personnel. Apparatus of the Invention A device for automatic control of moving a suspension of a mechanized rack, comprising a suspension position sensor, a stop relay and a direction selection relay, in the power supply circuit of which, respectively, one contact group of the suspension selector switch connected directly and another contact group connected through the isolating diodes and a suspension position switch synchronously coupled to a reversible electric actuator, characterized in that, in order to increase accuracy and reliably To address the device, the device is equipped with additional isolation diodes, and the suspension selection switch has a third group of contacts that are connected in series with the isolation diodes between the directional selection relay and the suspension position switch, the suspension position sensor being connected in series to the power supply of the stop relay.
