Definitions

  • the multipolar connection valve island may be a modular valve island and/or a quick configuration valve island.
  • Valve islands with multipolar connections are known, i.e., a set of a plurality of pneumatic valves for controlling devices, provided with a centralized energy power and air supply and connected to a programmable control unit. Valve islands are used to manage a given number of valves and to process the signals thereof. This allows, for example, actuators to be commanded using compressed air.
  • Valve islands are designed to manage groups of pneumatic valves which, connected to actuators, allow them to be commanded with compressed air.
  • the opening or closing of the valve mainly occurs by means of an electric command which powers a coil or solenoid of a solenoid pilot valve or solenoid electro-pilot electromechanically acting to allow or prevent a flow of compressed air to operate a respective pneumatic valve, which, in turn, will distribute, or not, compressed air to actuators.
  • each pneumatic valve of a valve island which may be monostable or bistable, for example 3/2, 5/2 or 5/3, is controlled by one or two solenoids, which receive an electrical signal to actuate the pneumatic valve associated therewith.
  • the pneumatic valve controls the direction of the flow of compressed air which operates an actuator or mobile element, such as, for example, a pneumatic cylinder.
  • Valve islands are connected to a pneumatic power supply line which supplies compressed air or to a vacuum generator, an electrical power supply line to supply power to the solenoids of the solenoid pilot valves, and an electrical communication line to control the operation of the valve island, where the electrical power supply line and the electrical communication line are two separate electrical lines.
  • valve islands of the known type the electrical signal between a main electronic board of the island and each of the solenoids occurs by means of physical wiring, according to a wiring diagram which is defined during the step of designing the island. Once the island has been structured and assembled, therefore, it is no longer possible to modify the wiring diagram thereof.
  • the electrical signal is transmitted to each of the solenoids of the solenoid pilot valves by means of physical electrical wiring with an interface conventionally consisting of a multipolar connector.
  • wiring which is purely physically point to point connected by means of wired electrical conductors or by means of conductors on a printed circuit, or with electronic communication systems with conventionally serial technology, may be provided.
  • the configuration is established during the step of designing the island, following which, once created, it is no longer possible to modify the wiring diagram thereof between each command electrical contact or pin of the multipolar connector and the solenoids of the valve island, statically determining the one-to-one correspondence of a command to the solenoid of the solenoid pilot valve of the corresponding pneumatic valve. Consequently, the connections between the positions of the solenoids and command pins of the multipolar connector or multipolar plug or multipolar socket, statically determined, limit the rearrangement of the modules of a valve island.
  • the multipolar valve island comprises one or more modules, each consisting of a base in which there are the channels intended to distribute the fluid under pressure or vacuum, power supplied by the head or heads to the possible connected modules and to the pneumatic valves.
  • the base allows the installation of up to two pneumatic valves, independent of each other and with specific functions, as described above, and up to two solenoids for each pneumatic valve for the electromechanical command of the pneumatic valves themselves by, for example, opening or closing a flow of compressed air.
  • an electronic microprocessor board is integrated, defined as secondary or second level, which has the following functions:
  • the multipolar connection valve island comprises one or more valve modules, each in turn comprising a base, in which the channels of the fluid under pressure or vacuum are present, and one or more pneumatic valves, for example two, with the relative solenoids mounted on said base and connected to said channels.
  • solenoid means a solenoid pilot valve or solenoid electro-pilot valve which, as it is known, comprises an electrically powered coil to actuate a movement of a mobile core to open or close a flow of compressed air towards the respective pneumatic valve.
  • the group of solenoid or solenoid pilot valve and the respective pneumatic valve is an indirectly operated solenoid valve.
  • the multipolar connection valve island comprises at least one head with connections for supplying fluid under pressure or to a vacuum generator.
  • the multipolar valve island comprises a microprocessor unit or main electronic board with processor, mounted on said at least one head with a multipolar connector or a multipolar connection socket for controlling said solenoids and for supplying power to the island.
  • the multipolar valve island comprises a main electronic board with microprocessor technology mounted on a housing made in said head, the main electronic board is connected to an output interface or connector, specific for being connected to the second-level electronic boards and to an input interface or multipolar connector with standard multipolar connection, such as, for example, a connector of the “D-SLIB” type for receiving serial communication commands or signals.
  • the serial communication commands or signals are organized according to the numbering of the multipolar connector used. If the multipolar connector has, for example, 25 electrical contacts, 24 electrical commands will be available, configured to communicate serial communication signals.
  • the 25th contact has the function of negative reference voltage, i.e., a return signal. In general with an n-pin connector, n-1 command signals will be available.
  • the main electronic board does not include an external electrical power supply, but it is directly powered by the command electrical voltage or command signal or solenoid command signal to command a respective solenoid or solenoid pilot valve, provided by an external command unit, such as, for example, a programmable logic controller, more commonly known as “PLC”.
  • PLC programmable logic controller
  • the main electronic board also powers the second-level electronic boards of each valve module, by means of the command electrical voltage.
  • each of said pneumatic valves is mounted in a removable manner and each of said solenoids or solenoid pilot valves is mounted in a removable manner on the relative base, and where each pneumatic valve is separable from relative one or more solenoids or solenoid pilot valves, such that all said pneumatic valves and all said solenoids or solenoid pilot valves of a respective valve module are selectively removable independently of the other ones from the respective valve module base.
  • valve island comprises two or more of said valve modules, one or more of them may be selectively removed, or that one or more of said valve modules may be selectively added.
  • the multipolar connection valve island is fully customizable without requiring any pre-established wiring diagram, since there is no physical connection by means of cables or tracks between each solenoid or solenoid pilot valve and a pin of the multipolar connector or multipolar socket or plug, nor any uniquely determined logical association between the pins of the multipolar connector and the possible solenoids of the valve modules.
  • said microprocessor unit comprises at least one main electronic board with microprocessor, male pins or male connector for the electrical connection to one of said valve modules.
  • Each valve module comprises a second-level electronic board with a relative processor, in turn comprising male pins or a male module connector for the connection to the second-level electronic board of an adjacent valve module and a module socket for the pins or male connector of said main electronic board or pins or male module connector of the electronic board of a second adjacent module.
  • each second-level electronic board of each module controls the solenoids or solenoid pilot valves of the module itself, which may, for example, be from 1 to 4, while said main electronic board of the multipolar valve island controls in series said second-level electronic boards of the modules, depending on the number of pins of the multipolar connector, or of the multipolar socket or plug.
  • a socket of the d-sub type for example with 25 pins, where 1 pin is used for the return signal
  • the remaining available pins connect and communicate in series with the solenoids present in the island, which may be a maximum of 24 for a 25 pin d-sub, or in general n-1 pin for an n pin d-sub.
  • the multipolar connection valve island can be configured using a configuration procedure that allows sequentially associating one pin at a time of the multipolar connector or the multipolar socket or plug to the first available solenoid, or in any case according to a sequence that is independent of the actual presence and electrical connection of the solenoids.
  • the multipolar island is progressively configurable, by associating the pin or electrical contact or command number 1 of the multipolar connector with the first electromechanical command, i.e., the first solenoid or first solenoid pilot valve, available starting from the valve module closest to the head which supports the main electronic board, and the pin or electrical contact or command number 2 of the multipolar connector with the second electromechanical command, i.e., the second solenoid pilot valve, available following the first solenoid or first solenoid pilot valve and so on, thus making the sequence dependent exclusively on the electromechanical commands alone, i.e., the solenoids or solenoid pilot valves, installed in the valve modules.
  • the first electromechanical command i.e., the first solenoid or first solenoid pilot valve
  • the multipolar connector pins are connected only to the solenoids which have been installed, while no multipolar connector pin is assigned to the empty stations, i.e., to the positions where the solenoid has not been detected.
  • the unconnected multipolar connector pins will therefore remain unused.
  • the multipolar connector pins associated with the absent solenoids will still be used.
  • the second- level electronics of the module acquires the number or presence and position of the solenoids or solenoid pilot valves mounted in the respective valve module
  • the main electronic board in the head acquires the consistency of each module, i.e., the number of solenoids or solenoid pilot valves installed and the relative position, and performs, according to the above criterion, the assignment of the electrical contact or pin or command of the multipolar connector of the head to a specific solenoid or solenoid pilot valve present in the modules.
  • the processor of the main electronic board of the island communicates with the processors of the second-level boards of the modules with a dedicated serial communication signal, which activates and communicates only with the solenoid to be used.
  • the configuration will be saved, i.e., the sequence of stations and solenoids present will be saved.
  • the main electronic board of the island will therefore be automatically reconfigured in a correct manner. It is also possible to reconfigure the island in the event of changes thereto.
  • Such feature therefore allows the island to be assembled in a completely customizable manner, thus being able to add/remove pneumatic valves and solenoids and valve modules both during the initial first assembly step as well as during the subsequent steps of restructuring the island, without having to physically modify the electrical contacts of the island itself in any manner.
  • Figure 1 shows a three-dimensional view of a valve module 100 partially exploded in a constructional example according to an embodiment, where the base 400, two valves 200, 200', a solenoid or pair of solenoids 300, 301 , 300', 301 ' for each valve 200, 200', a second-level electronic board 110, with a control processor for the solenoids of the module 100, and the cover 120 of the solenoids 300, 301 , 300', 301 ' are shown.

  • Figure 4 shows a fully assembled island 500 in an explanatory example.
  • Figure 5 shows a three-dimensional view of a partially disassembled island
  • Figure 6 shows in a diagrammatic manner, in an example, the configuration step in the situation in which the solenoids of four valves 1 , 2, 3, 4, of which three 1 , 3, 4 are bistable with two solenoids each A1 , B1 , A3, B3, A4, B4 and one 2 is monostable with a single solenoid A2, are connected to a socket SUB-D 25 with 25 pins, in which, as shown in the diagram, the first 7 pins P1 , P2, P3, P4, P5, P6, P7 of the multipolar connector are sequentially connected to the 7 solenoids present A1 , B1 , A2, A3, B3, A4, B4, thus ignoring the empty station of the absent solenoid.
  • Figure 7 shows a reset and learning device configured to be connected to the multipolar connector of the multipolar island so as to reset the pre-existing configuration in the main electronic board and proceed to a new configuration of the multipolar valve island, where the pins P1 , P2, of the multipolar connector 560 of the island 500 will be sequentially reconnected to each of the solenoids present in the island, thus ignoring possible empty stations.
