Definitions
- the present invention relates to an enhanced security double door connection device.
- Such a double-door device provided with a multiple-safety control is for example known from document FR 2 695 343.
- Each volume is closed by a door mounted in a flange.
- Each door is secured to its flange either by a bayonet connection or by a hinge and a locking system and the two flanges are intended to be secured to each other by a bayonet connection.
- one of the closed volumes is formed by an isolator and the other volume is formed by a flexible container, also referred to as a sealed transfer bag.
- connection part carried by the insulator is designated alpha part and the connection part carried by the container is designated beta part.
- Gaskets are provided on the alpha part and on the beta part to ensure sealing between the connected volumes.
- the beta part comprises a beta flange closed by a beta gate, the beta flange and the beta gate cooperating with each other by a bayonet connection
- the alpha part comprises an alpha flange closed by an alpha gate, the alpha gate being articulated on the alpha flange by a hinge. Sealing between the beta flange and the beta door is ensured by a seal housed in the beta flange.
- connection between the transfer bag and the enclosure is made by mechanical cooperation of the beta flange and the alpha flange by a bayonet-type connection. This mechanical cooperation ensures both the mechanical connection and the sealing of the connection.
- the tight connection cycle is as follows:
- the container carrying the beta part is approached to the alpha part, the ears of the beta flange enter notches of the alpha flange, and the beta door ears enter notches of the alpha door.
- the container is rotated, for example clockwise, the ears of the beta flange rotate and slide in a groove of the alpha flange.
- the rotation of the container causes the rotation of the beta door, which causes the connection between the beta door and the alpha door by the bayonet connection.
- the two doors are then joined together.
- Each lug of the beta gate then comes to rest against a circumferential stop carried by the alpha gate.
- the container is still rotated, due to the bearing of the ears of the door beta against the circumferential stops on the door alpha, the rotation of the container causes the disconnection between the door beta and the flange beta.
- the beta door Simultaneously with the pivoting and sliding of the lugs of the beta flange in a groove of the alpha flange, due to the friction of the seal carried by the alpha door, the beta door is held stationary in rotation and the beta door is disconnected from the beta flange . Each lug of the beta flange then bears against a circumferential abutment carried by the beta door.
- the container is further rotated, due to the beta flange ears pressing against the circumferential stops on the beta door, container rotation causes the beta door to rotate causing the connection between the beta door and the alpha door by the bayonet connection.
- the two doors are then joined together. From inside the cubicle, the alpha door is unlocked and the set of two doors can be swiveled inwards around the hinge pin.
- the transfer between the two volumes can take place.
- the disconnection cycle is as follows:
- the container is rotated counterclockwise. Due to the friction between the gates, the beta gate remains stationary in rotation, causing the beta gate and the beta flange to connect. Then, circumferential abutments carried by the beta flange bear against the circumferential abutments of the beta door, causing the rotation of the beta door relative to the alpha door and their disconnection. The container is also disconnected from the alpha flange. The container can then be removed from the flange.
- Such a double-door device provided with a multiple-safety control is for example also known from document EP 2766 121.
- This device comprises a manual control member for opening the doors and four locks, two of which prevent any opening maneuver as long as the container door is not present and the container flange is not fully connected to the alpha flange.
- a third lock prevents any disconnection of the two flanges after crossing an intermediate locking position by the control member.
- a fourth lock prevents the control member from returning to its initial position when the doors are open. This double door connection device is satisfactory.
- the first two latches are at least partially disabled when the connection of one of the ears of the beta flange to the alpha flange is detected.
- a protruding rod of the alpha flange is pushed back by the lug of the beta flange, which contributes to the deactivation of the two locks.
- Beta flanges can deteriorate, for example become deformed or even break during manipulations, notably the connecting lugs to the alpha flange which extend radially outward from the flange.
- the inventor has found that if one or more of the three other ears of the container whose presence is not detected, are damaged, for example broken or deformed, and the ear whose presence is detected is in a sufficient state to ensure the deactivation locks, the cell door lock can be disabled, while the connection is not necessarily secure due to the deterioration of one or the other ears. In fact, this partial deterioration may result in poor pressing of the seal against the alpha flange and therefore a risk of leaking, which may cause a loss of confinement.
- a double-door sealed connection device which comprises a cell flange and a door, the cell flange comprising bayonet connection means intended to cooperate with a flange of an object to be connected , the flange of the object comprising ears cooperating with the bayonet connection means, said cell flange comprising means for detecting the presence of each of the ears of the flange of the object to be connected.
- the sealed connection device comprises motorized unlocking means, the detection of the presence of all the ears then results in the sending of a signal to control means which generate an order to the unlocking means of unlock. Conversely, if one of the ears is not detected, unlocking is prohibited.

- the cable serves only for the power supply and the signals are transmitted by wireless means, for example by radio wave.
- the sensors 52 are electrical switches, optical sensors implementing, for example, laser detection in barrage or in detection.
- the detection is a purely mechanical detection, in which the displacements of the rods 48 resulting from the correct positioning of the beta container cause the mechanical unlocking of the cell door. The opening of the doors is controlled elsewhere.

- the control unit sends signals to the first motor to command the unlocking of the cell door, and to the second motor to command the opening of the doors. These signals are only sent if all four sensors detect all four rods. If at least one detection signal is not emitted, no unlocking or opening is permitted. It should be noted that the presence of the container door is also detected by means provided for this purpose.
- the operation of the device will now be described.

- the axis of the cell flange and the axis of the container flange are aligned.
- the sensors detect the displacement of the rods and each emit a detection signal to the control unit (FIG. 7B), the control unit issues an order to the lock motor to unlock the cell door and to the opening motor to open the doors.
- the container flange has one or more broken or deformed lugs so that they do not cause the detector rods to slide (FIG. 7A) and the emission of detection signals, the unlocking of the cell door is not allowed by the control unit. This can issue a fault signal for the operator.
- the invention offers a high level of safety since the risks of rupture of the sealed atmosphere due to a defective flange are avoided.
- the container is sent to scrap or for repair.
- the present invention also applies to cells in which the unlocking of the cell door and/or the opening of the cell door and of the container door are carried out manually.
- the operator accesses the lock using a glove mounted in a round glove located close to the cell flange.
- it is the operator who decides to unlock the cell door according to the information sent by the detectors. If the operator detects that all the sensors emit an ear detection signal, he decides to unlock the cell door, otherwise he removes the container for disposal or repair.
