- At least a pair of cameras 25a or 65a, and 25b or 65b comprised in the hooking group 10, 50 is necessary to allow the assigned operator, as specified below, to certify that they are locked on the basis of the images detected by these cameras, which can also be stored on the computer system where the operator works.
- the carriage which carries the fastening operation is to approach the wagon to be hooked, whether it has stopped in a fixed position or is in movement, for example in the queue to a moving convoy. Then the terms of engagement can be checked through sensors and information from this platform in the station or on the locomotive. In the moment in which the signals relating to the distance between the wagons, the speed, the horizontal and vertical alignment of the hooking groups, and other useful parameters, from sensors are such that the computer platform of the wagon can order this engagement, the terminals of the coupling groups are prepared in order to install the additional protrusions.
- the actuator not shown in the figure allows movement in the vertical of one or the sliding plate 12 or 52 of the first or the second hooking groups 10 or 50 until the pins 18 and 58 find themselves aligned. Just such an alignment has occurred, the coupling is realized between the complementary protrusions of the terminals 18 and 58. At this point, the jaws are closed and the bellows actuator continues forward within the protrusions so as to enable the connection of electrical, compressed air and data cables.
- the 11A-11D figures show the phases of coupling of the terminals 18 and 58: 1) alignment; 2) interlocking of complementary protrusions; 3) closing of the jaws of the jaw locking devices; 4) physical connection of pneumatic tubes, and electrical and electronic cables. It is, therefore, the wagon signal locked is given to the control panel.
- the completion of the coupling maneuver filmed by cameras 25a, 25b, 65a, 65b, the images that frame each hooked jaw, can be transmitted to a monitor that can be expected on the cab of the tractor in which the driver, visually verified perfect coupling maneuver occurred, may confirm, in a manner provided for in the management information system present on the tractor, the transaction is fair, certifying the engagement itself.
- the images can be transmitted to this system where an attendant operator can confirm certifying that they are locked.
- the images of the coupling can, then, be stored on the system to which the certification of coupling is entrusted (eg. Of the tractor vehicle, of the station, etc.).
- the engagement / release phases can take place by making use of "intelligent" cars of an "intelligent” railway train.
- the Applicant means the wagons carriages of a rail transport system with automatic train composition described in the above mentioned patent already issued to the Applicant.
- the coupling can take place both with a convoy already equipped with traction unit, both with a convoy in the formation in which the functions normally operated from the tractor unit are assumed by a "master” wagon or by a system at the station, either to another isolated carriage with which a new convoy will begin to form (in this case the wagon to which is hooked the wagon will be the "master”).
- the "master" wagon or the system at the station will be indicated only as “driving”.
- the sequence of the above operations starts by a request made to an isolated wagon to perform the fastening operation to another wagon of a convoy in the composition.
- the carriage starts in the required direction and activates the sensors present in the first hooking group looking for the corresponding sensors of the second hooking group of the other wagon, identifying them with the sensor codes that were transmitted, for example by tracing with transponder.
- the carriage to which it will have to hook will alert and adjusts itself to engaging, accepting the same docking operation.
- the information provided by the sensor pairs on the two carriages are used by the management system of the wagon to hook to determine the distances between the wagons and the approach speed.
- the existence of the minimum alignment between the terminals with protrusions will be determined verifying the relative positions of the two apparatuses either horizontally or vertically, watching in the approaching time the maximum deviations in the two directions and, if necessary, it may be provided for the possibility to operate an optimal alignment of the terminals with protrusions also by means of the actuators.
- the approach maneuver is authorized and also the insertion of protrusions in the complementary ones.
- the release mechanism that automatically closes the two jaw elements which can lock the seats rigid bodies on the two wagons to be hooked can be activated.
- a control system may enable the insertion of the pneumatic fittings of the braking system, the electrical and electronic connections, for example by means of the actuator which acts on the terminal.
- the hooked wagon switches the management of the hooked wagon from isolated to hooked, and passes control of the wagon management to drive the convoy.
- the operator responsible for the certification of engagement will formally confirm the completion of the transaction after it, warned by appropriate screen message, will have viewed the images of surveillance cameras. The same images will be properly stored for future views for inspection and controls with indications of date, time, wagons concerned operator who confirmed the operation.
- the wagon separating from the convoy asks for confirmation of the release to the wagon from which it has to disengage by means of the sensors verify of the identity of the wagons. Once the confirmation is obtained, the wagon to release will acquire the self-control of the wagon activating the switching of the control of the wagon from hooked to blocked. Both wagons will activate the actuators to disconnect the pneumatic, electrical and electronic connections. Upon completion of this operation confirmed from one wagon, it will proceed to operate the actuators to open the jaw elements to block the wagons. This operation will also charge the mechanical elements to allow a subsequent maneuver of engagement.

Description
- The present invention relates to a system for automatic coupling and release of vehicles travelling on the rail network.
- In particular, the present invention relates to a system for automatic coupling and release of vehicles travelling on the rail network, of the type of wagons and rail cars, and traction means circulating on tracks, either of the traditional type or of the type defined intelligent in the sense of the term introduced with reference to the wagons of a rail transport system with automatic train composition described in the Italian patent No.
0001416154 - As is known, currently the operation of coupling and uncoupling between railway wagons is performed by using systems that require the presence of operators to connect the wagons between them, both in the traction components and in the brake components, and also possibly for connections of the electric type. Such systems are not automatic, but they are subject to the presence of operators.
- To try to overcome this problem, automatic coupling systems have similar to those originally designed by Scharfenberg been developed, but their operation always assumes that one of the two vehicles is stationary and the other one approaches with extremely low berthing speed. Therefore they are not suitable to particular applications, such as the coupling between the moving carriages, since they have no system to check beforehand in an automatic way the existence of the coupling conditions.
- Also the way in which some automatic couplers have been developed makes them unsuitable for goods transport where extremely high tensile forces are required, generally not enduring stresses of a certain relevance.
- Finally, current systems are not designed to make frequent coupling and uncoupling operations, and do not provide that, in addition to the traction connections, to the pneumatic components for the braking system and electricity for the services, also electronic type connections are also present between the systems to be connected in the coupling phase, to allow the exchange of information between computer systems located on two vehicles to attach / detach.
- It isn't also provided a verification remote system to check the connections, whose certification procedure is always entrusted to an operator.
- Moreover, the coupling maneuver is not assisted by any sensor component that guides the phases and the correctness of the operation. Therefore, these systems do not allow an exchange of information to occur if computer systems are present in the two vehicles to engage or disengage, such as those present in the "intelligent" wagons of the mentioned patent of the same Applicant.
- Furthermore, with the known systems, the existing circulating wagons should be standardized with the changing of the elastic connection system to the other wagons in a convoy.
- A solution to these problems can be found in the patent
DE1131720 which describes the coupling between two hooking groups of two different vehicles having a vertical alignment apparatus. - Anyway, the problem of this solution is that the coupling can't be performed in an automatic mode.
- The object of the present invention is to provide a system for automatic coupling and release of vehicles travelling on the rail network that allows to automatically perform the necessary maneuvers with speed, safety and high reliability also as a result of the coupling operations and very frequent release, allows the elasticity between the two vehicles also during acceleration of the train to which the system is applied and which is easily adapted also to existing circulating wagons, thus having characteristics such as to overcome the limits which still affect the previously described solutions with reference to the known technique.

In the following functions of the drive, the "master" wagon or the system at the station will be indicated only as "driving". By way of example, relatively to the docking maneuvers disclosed in the previous patent to achieve such automatic composition of a train, the sequence of the above operations starts by a request made to an isolated wagon to perform the fastening operation to another wagon of a convoy in the composition. The carriage starts in the required direction and activates the sensors present in the first hooking group looking for the corresponding sensors of the second hooking group of the other wagon, identifying them with the sensor codes that were transmitted, for example by tracing with transponder. The carriage to which it will have to hook will alert and adjusts itself to engaging, accepting the same docking operation. During the approach the information provided by the sensor pairs on the two carriages are used by the management system of the wagon to hook to determine the distances between the wagons and the approach speed. In the vicinity of the contact, always through the sensors the existence of the minimum alignment between the terminals with protrusions will be determined verifying the relative positions of the two apparatuses either horizontally or vertically, watching in the approaching time the maximum deviations in the two directions and, if necessary, it may be provided for the possibility to operate an optimal alignment of the terminals with protrusions also by means of the actuators. Once the alignment positive verification, the approach maneuver is authorized and also the insertion of protrusions in the complementary ones. After the mechanical action of the thrust given by the insertion of protrusions in the complementary ones, the release mechanism that automatically closes the two jaw elements which can lock the seats rigid bodies on the two wagons to be hooked can be activated. When the lock of the jaws is occurred, a control system may enable the insertion of the pneumatic fittings of the braking system, the electrical and electronic connections, for example by means of the actuator which acts on the terminal. Once the perfect execution of the operation and efficiency of all connections (mechanical, pneumatic, electrical, electronic) is verified, the hooked wagon switches the management of the hooked wagon from isolated to hooked, and passes control of the wagon management to drive the convoy. The operator responsible for the certification of engagement will formally confirm the completion of the transaction after it, warned by appropriate screen message, will have viewed the images of surveillance cameras. The same images will be properly stored for future views for inspection and controls with indications of date, time, wagons concerned operator who confirmed the operation.
- For the release operations starting with the order transmitted from the tractor to the two wagons that must come off, to perform the sequence of operations which will lead to the separation of the wagons. The wagon separating from the convoy asks for confirmation of the release to the wagon from which it has to disengage by means of the sensors verify of the identity of the wagons. Once the confirmation is obtained, the wagon to release will acquire the self-control of the wagon activating the switching of the control of the wagon from hooked to blocked. Both wagons will activate the actuators to disconnect the pneumatic, electrical and electronic connections. Upon completion of this operation confirmed from one wagon, it will proceed to operate the actuators to open the jaw elements to block the wagons. This operation will also charge the mechanical elements to allow a subsequent maneuver of engagement.
