Description

Technical Field

[0001] This application relates to a transfer system for a sealing enclosure that defines a closed volume intended for connection to another closed volume, the sealing enclosure including a sealing connection means located between the two closed volumes. The invention also relates to a method for actuating said transfer system. Background Technology

[0002] In many industrial sectors, including pharmaceuticals, medical, agri-food, and nuclear industries, there is a need or desire to perform certain tasks in confined environments to protect personnel from effects such as radiation or toxicity, or conversely, to be able to perform these tasks in sterile or dust-free environments, or ultimately in environments that are both sterile and dust-free.

[0003] Transferring equipment or products from one enclosed volume to another without compromising the seals of each volume relative to the outside presents a challenging problem. This problem can be solved using a double-door connection device.

[0004] For example, such a double-door device with multiple security controls is known from document FR 2 695 343. Each volume is closed by a door mounted on a flange. Each door is secured to the flange of the door via a bayonet connection, and the two flanges are designed to be secured to each other via bayonet connections. This system is also referred to as RTP, which stands for "Rapid Transfer Port".

[0005] In cases where one enclosed volume is formed by a container and the other by an enclosure, such as a storage bin, the following transfer is performed. The container's flange includes lugs on its outer periphery designed to mate with recesses in the storage bin's flange. The container's flange is inserted into the storage bin's flange, the container oriented so that the lugs mate with the recesses. A first rotation of the container along the axis of its door allows the container's flange to be secured to the storage bin's flange via a bayonet connection. A second rotation of the container along the same axis, succeeding the first rotation, pivots the container's door relative to the container, thereby ensuring the connection to the storage bin's door via another bayonet connection and the separation of the new assembly formed by the two doors attached to the door and the storage bin's flange. A handle control located in the storage bin allows the unlocking of the safety mechanism and unobstructed passage between the two volumes. In a sterile environment, the outer surfaces of the two doors are in sealed contact with each other, preventing contamination of the interior of the volumes or the storage bin's internal environment.

[0006] The container flange includes a seal that, when secured to the flange of the storage bin, defines a passage between the interior of the container and the interior of the storage bin together via the two flanges. The tip of the container flange seal that does not contact the storage bin flange is called the "contamination ring" or "concern ring." Care should be taken to ensure the integrity of the container flange seal, and contact with the contamination ring during transfer should be avoided to prevent contamination of the seal.

[0007] This type of enclosure is used in the manufacture of products in a controlled environment, such as in the pharmaceutical industry for drug manufacturing and packaging. For example, a filler line is incorporated into the enclosure. Objects, such as vials or caps, from the outside can then be passed toward the interior of the enclosure. The object is contained in a bag-like component with a flange and a door, the flange being sealed to the flange of the enclosure. To facilitate the transfer of objects, for example, to pour objects into a vibrating bowl-like component of the filler line, a transfer system is implemented in the enclosure. This system includes elements forming a funnel, referred to as chute, and is designed to fit as a support or inside the flange of the enclosure to receive objects from the bag-like component and guide them toward their destination, such as the vibrating bowl-like component. Positioning the chute in an opening in the container flange allows for the covering of contamination rings.

[0008] An example of such a transfer system is described in document EP3581339. The chute is hinged relative to the wall of the enclosure between a mating position and a separated or stationary position. In the mating position, the chute abuts against the flange of the enclosure and engages with the opening of the enclosure. In the separated or stationary position, the chute moves away from the opening of the enclosure to avoid interfering with the door of the enclosure returning to its original position.

[0009] The chute is hinged to an arm, which itself is rotatably hinged to the wall of the enclosure. When the chute is to be positioned over the opening, the arm rotates along the wall and the direction of the chute, abutting against the flange of the enclosure and engaging with the opening. To remove the chute, the arm rotates in the opposite direction. The transfer system has a relatively reduced size. However, when docking the connection, the rotational movement of the chute within the enclosure can cause friction between the docking ends of the chute and the contamination ring, potentially damaging the seal. Summary of the Invention

[0010] Therefore, the purpose of this application is to describe a transfer system for sealing enclosures that limits friction between the chute and the contamination ring.

[0011] The aforementioned objective is achieved through a transfer system designed for installation within a sealing enclosure, comprising means for sealing connection to an enclosed volume. The connecting means includes a longitudinal axis, and the transfer system includes a chute hinged to a portion of the enclosure via a hinged mechanism, thereby enabling the chute to move coaxially with the longitudinal axis of the connecting means, at least when approaching the connecting means. Therefore, compared to systems where the chute engages the connecting means via rotational movement, friction between the chute and the contamination ring is significantly reduced.

[0012] In one embodiment, the articulation device includes two arms connected by pivot hinges, one arm being connected to a chute via a pivot hinge, and the other arm being connected to an enclosure via a pivot hinge, each pivot hinge being motor-driven. Motor control allows the chute a large degree of freedom of movement relative to the enclosure, and the implementation of two arms allows the chute to move in a direction coaxial with the axis of the connecting device, at least during docking of the chute with the connecting device and during disengagement of the chute from the connecting device.

[0013] In another embodiment, the articulation device includes two arms and two motors.

[0014] The motor of the articulated device can be controlled, for example, during the disconnection phase, such that the chute successively has a first fully translational movement in a direction coaxial with the axis of the connecting device and a second movement intersecting the axis of the connecting device, for example, orthogonal to the axis of the connecting device.

[0025] Preferably, the transmission system includes a third pivot joint located between the second arm and the inclined groove, and a third electric motor for rotating the inclined groove relative to the second arm, the third motor being controlled by a controller.

[0026] Advantageously, the first motor is coupled in the first pivot joint and / or the second motor is coupled in the second pivot joint and / or the third motor is coupled in the third pivot joint.

[0027] In one implementation, the first arm and / or the second arm is bent.

[0028] According to additional features, the slant is removably mounted on the second arm.

[0029] Another object of this application is a sealing member that defines a first enclosed volume and includes a transfer system according to the invention and means for sealing connection to a second enclosed volume, the connection means being mounted in the wall of the sealing member and including a flange and a door.

[0030] For example, the hinged device is fastened to the flange of the connecting device.

[0031] In an advantageous embodiment, the flange includes a channel located between the interior and exterior of the enclosure, through which a device for electrical connection to a motor passes. The connection device may include a latch for opening the door and an automation device for pivoting the door, activated by at least one motor, and the device for electrical connection to said at least one motor may pass through the channel.

[0032] According to the additional features, the enclosure includes a system for generating laminar flow on one side of the connecting device, and the hinge device is fastened in the enclosure relative to the connecting device, opposite to the system for generating laminar flow.

[0033] In another embodiment, the hinge device is fastened to a wall different from the wall on which the connecting device is installed.

[0034] Advantageously, the enclosure includes a device (S) for detecting the configuration of the transfer system and / or the open state of the connecting devices.

[0043] In cases where the enclosure includes means for generating laminar flow along a wall including a sealing connection, the chute can advantageously be positioned in the axis of the laminar flow at the end of the separation phase. Attached Figure Description

[0058] exist Figure 1A , Figure 1B and Figure 2 In the image, an example of a sealing enclosure shown in a transparent form can be seen, which is provided with an example of a sealing transfer system S1 according to the first embodiment, which is shown in different positions.

[0059] Enclosure 2 includes walls defining a sealed volume. At least one of the walls 4 includes a means D for sealing connection to an external sealing system, such as another enclosure, a bag-type rigid container, or a flexible container. The means D is designed to allow a sealed connection between the internal volume of the enclosure and the internal volume of the external system, and is designed to achieve a seal transfer between the two volumes to protect objects contained within the sealed volume and / or protect the external environment of those objects. For example, enclosure 2 may be part of an isolator system, specifically an isolator containing area, a sterile containing area, or a radioactive containing area, which may be used in the manufacture of products, for example, in the pharmaceutical, agri-food, or nuclear industries.

[0060] Examples of sealing connection devices are described in FR 2 695 343 and US 9 754 691.

[0061] The sealing connection device D includes a flange 6 mounted in the wall 4 and defining the opening 8, and a door 10 designed to close the opening 8 in a sealing manner. The sealing connection device D also includes components for connection to an external system, such as a container C. Figure 10 The container C also includes a flange 9 that engages with the opening and a door 11 that seals the opening. For example, the device for connecting flanges 6 and 9 is a bayonet type. Each door is also connected to the flange of the door via a bayonet connection. The connecting device is axially symmetrical about axis X1.

[0062] Reference Figure 10 A brief description of an example of a procedure for sealing a container to an enclosure. The sealed container is shown in dashed lines before its connection to the enclosure. The container contains an object O, schematically shown, which is to be transferred to the enclosure. The transfer system is not shown.

[0063] The container's flange 9 is securely fixed to the sealing member's flange 6 via a bayonet connection. Simultaneously, the container's door 11 and the sealing member's door 10 are also securely fixed to each other via a bayonet connection. The outer surfaces of the doors 10 and 11 are isolated from the internal volumes of the container and the sealing member. The assembly formed by the two doors 10 and 11 fixed to each other can be moved apart by pivoting the assembly about its axis and then into the sealing member, thereby opening a passage between the two volumes. The two volumes are then sealed together, and the passage allows for the transfer of objects between the two volumes.

[0064] The container flange 9 carries a seal that contacts the outer surface of the sealing flange 6, which helps to define the passage between the two volumes. The tip of the container flange seal that does not contact flange 6 is a line referred to as the “critical line”, “contamination ring”, or “circle of concern”.

[0065] The enclosure includes a transfer system S1 that allows objects from the outside to be guided toward an area of ​​the enclosure's internal volume. For example, these objects are lids contained in bag-like components and these lids are tucked into the enclosure. System S1 is designed to facilitate the handling and / or transfer of objects / components in the enclosure 2, for example, to facilitate the supply of objects / components to a conveyor belt or, during subsequent processing, to transfer them to a separate sealed container via another sealing connection.

[0066] The transfer system S1 includes a component 14 that ensures the flow of the guided object, which is called a chute and forms a funnel of some type.

[0067] In the example shown, the inclined groove 14 is cylindrical, has a longitudinal axis X2, and includes a mating end 17. Figure 2 The other end 18 has a circular section, and the mating end 17 is designed to fit into the channel between the two enclosures and engage with the opening when the door is open. The other end 18 forms a pouring end oriented toward the area where an object in the enclosure is desired to be guided. In the example shown, the pouring end is cut with a plane inclined relative to its axis of rotation X2, thus having a beveled shape on the pouring end. The groove is designed to present a mating position and a disengaged position, in which the mating end 17 is received in a channel formed in the two flanges. Figure 1A and Figure 1B In the separated position, known as the rest position, the chute 14 moves away from the opening and waits for a new transfer. Figure 2 ).

[0068] Alternatively, the groove may have, for example, a curved shape, in which case axis X2 is the axis of the mating end 17.

[0069] Advantageously, the mating end 17 is covered with a protective strip made of a soft material (not shown), such as an elastomer.

[0070] The transfer system includes a device 20 for hinged to the chute relative to the connecting device, the hinge device 20 being mounted on the enclosure.

[0071] The hinge device 20 includes a first arm 22 and a second arm 24, which are connected to each other at one of their longitudinal ends 22.1 and 24.1 by a first pivotal hinge 26 having an axis Y1. Figure 2 and Figure 6 The first arm 22 is fastened to the enclosure via a second pivot hinge 28 having an axis Y2 at the other longitudinal end 22.2 of the first arm. The inclined slot 14 is mounted on the other longitudinal end 24.2 of the second arm via a third pivot hinge 30 having an axis Y3. The axes Y1, Y2 and Y3 are parallel to each other and orthogonal to the axis X1.

[0072] The transmission system also includes an actuating device for arranging the spur 14 to move relative to the connecting device D. Advantageously, the hinge is motor-driven, and even more advantageously, the hinge includes electric motors M1, M2, and M3 at the first pivot hinge 26, the second pivot hinge 28, and the third pivot hinge 30.

[0073] Control unit UC (in) Figure 6 (Illustrated schematically) Individual commands are generated for each electric motor M1, M2, M3. Individual motor control provides greater freedom in the construction of the chute's trajectory relative to the connecting device. This greater freedom allows adaptation to various environments within the enclosure and thus avoidance of obstacles. Each motor M1, M2, M3 includes an encoder, which allows precise control of each of the rotating axes, and therefore the relative positions of arms 22, 24 and chute 14, as well as the positions of the arms and chute relative to the connecting device. Advantageously, a device S is provided for detecting the configuration of the transmission system and / or the open state of the connecting device. The trajectory configuration is obtained by programming the motor control software and acting on servo control parameters such as the rotational speed and rotational angle of each motor. Sensors can be implemented to determine the positions of the arms and chute relative to the connecting device and the wall of the enclosure.

[0074] In the case of an automatic connection device, where the opening of the door is driven by a motor, the control unit may be shared by both the control of the transmission system and the control of the connection device, and the control unit may be configured to prevent the door from closing when the chute is in place in the channel, and / or the control unit may be configured to prevent the transmission system from being actuated when the door is closed.

[0075] Each motor M1, M2, M3 is advantageously coupled in a pivotal articulation 26, 28, 30 actuated by these motors, such as Figure 6 The kinematic diagrams are shown in the figures. Each motor comprises a shaft that directly forms the axis of the pivot hinge, without a speed reducer or gear and / or belt drive system. This arrangement of the motors allows for a compact transmission system and reduces embedded mass. For example, these motors are 24V DC geared motors equipped with brakes and encoders.

[0076] Since the motor shafts are parallel to each other, the hinge moves in a plane orthogonal to axes Y1, Y2, and Y3.

[0077] Now refer to Figures 3A to 3C A preferred trajectory for moving a chute is described. This trajectory includes stages for docking the chute onto a connecting device and stages for disconnecting the chute from the connecting device or moving it away from the connecting device. The trajectory for each stage comprises at least two substantially identical but reversed portions.

[0078] Considering the disconnection and docking phase: When the inclined groove is docked on the connecting device, the axis X2 of the inclined groove is approximately collinear with the axis X1. Figure 3A ).

[0079] In this application, "generally collinear" should be understood as two parallel axes being separated by a distance of at most 5 mm, preferably at most 1 mm, or intersecting at an angle of at most 5°, preferably at most 1°.

[0080] exist Figure 3B In the first portion of the trajectory shown, the chute 14 has a translational movement away from the connecting device, such that the axis of the chute remains substantially collinear with axis X1, thereby limiting friction with the contamination ring and flanges 6, 9. The movement in this first portion is sufficient to position the mating end 17 of the chute outside the connecting device, for example, within a range of several centimeters, such as about 5 cm. In this portion, two or three motors are simultaneously controlled to keep axis X2 collinear with axis X1 and to ensure the deployment of the hinge device. Figure 3B In the trajectory example, three motors, M1, M2, and M3, are enabled.

[0081] exist Figure 3C In the second part of the trajectory shown, the motor is controlled to cause the swashplate 14 to move in a translational manner along the axis Z, which is orthogonal to axis X1 and orthogonal to axes Y1, Y2, Y3. In this second part, two or three motors are simultaneously controlled to keep axis X2 in the X direction. Figure 3C In the trajectory example, three motors, M1, M2, and M3, are enabled.

[0082] The axis X2 of the inclined groove remains parallel to the axis X1 throughout the entire movement of the inclined groove. The inclined groove is fitted against the wall of the enclosure below the connecting device, thereby reducing the size of the inclined groove in the enclosure.

[0083] The docking trajectory includes a second part, followed by the first part.

[0084] Advantageously, the disconnection track may include a third section in which a motor is actuated to position the arm and chute along a wall, the chute having an axis X2 parallel to the wall. Advantageously, the third section includes a rest position of the chute, thereby further limiting the size of the chute and its effect on laminar flow in the enclosure. This position is... Figure 5 As shown in the image.

[0085] It should be understood that this example of a trajectory is not limiting. Specifically, in the second part, the chute can move based on a combination of partially linear and partially non-linear, or only non-linear, motion. For example, it could be provided that after a translational motion away from the connecting device, the motor is controlled to orient the axis of the chute in the Z direction, such as... Figure 2 As shown. According to Figure 2 The transfer system is quite large in size within the enclosure. Preferably, the movement on the second part is selected to limit the size of the transfer system within the enclosure.

[0086] In the example shown, and preferably, the hinge is fastened to the connecting device, more specifically to the flange 6, which avoids having to pierce the wall of the enclosure to secure the transmission system.

[0087] Furthermore, when at least a portion of the connecting device is automated, for example by implementing one or more electric motors to control the latch of the door of the connecting device and to control the opening of the door of the connecting device, the cables of the motors of the transmission device and the motors of the connecting device come together and extend through the hole formed in the flange.

[0088] This component achieves a high level of integration and simplifies the operation of equipping enclosures.

[0089] Preferably, the transfer system is located below the opening 8, and thus below the channel, fastened to the lower portion of the flange. This is advantageous when laminar flow is applied in the enclosure. In practice, laminar flow typically occurs at the top of the enclosure. When the connecting device is mounted on a vertical wall, considering the laminar flow direction, the transfer system positioned below the opening of the connecting device, i.e., downstream of the opening, will not obstruct the flow in front of the opening.

[0090] However, other settings can be considered.

[0091] In fact, it is of particular interest that the chute is positioned on the laminar flow axis in its resting position. Advantageously, in the resting position, the chute is vertically oriented, thus orienting the chute to resemble laminar flow.

[0092] exist Figure 4 In the middle, the transmission system S1 is positioned above the opening of the connecting device, and the first arm 22 is fastened to the flange 6.

[0093] The transfer system can also be fastened to the wall of the enclosure, for example, to the wall of the load-bearing connection device, preferably above or below the connection device, which can meet the setting and size constraints in the enclosure.

[0094] exist Figure 7 In the image, an example of the second implementation of the delivery system S2 can be seen.

[0095] In this example, the transfer system S2 is fastened to a wall different from the wall supporting the connecting device. This wall is, in this example, a lateral wall located on the side of the hinge of the door of the connecting device. The transfer system includes a second arm 124 with an elbow.

[0096] In this embodiment, the hinge device includes two arms 122, 124, two pivotal hinges 126, 128 having axes Z1, Z2 respectively, and two motors respectively coupled in the pivotal hinges 126, 128, with arm 124 rigidly fastened to a groove 114. The implementation of the bending arm 124 allows the system to be positioned in locations typically excluded due to proximity to doors or latches. In this example, the bending arm forms a right angle; any other angle can be considered and selected according to the settings.

[0097] This second embodiment allows for the release of areas for the passage of components and areas for laminar flow in the stationary position of the chute. This second embodiment provides free volume within the enclosure for the components to be handled, for example, by a robot.

[0098] In this example, the enclosure 2 includes a conveying system such as a conveyor ramp or conveyor belt T, on which an object transferred from the container via a chute will travel. When the chute is in the docking position, the end 118 of the chute 114 is directly above the conveyor belt T.

[0099] The motor is actuated to cause the spur groove to move according to a trajectory, including at least one translational movement away from and towards the connecting device. In this configuration, the axis of the hinge is vertically oriented.

[0100] Alternatively, the transmission system is fastened to the wall of the supporting connecting device, but offset laterally relative to the center of the connecting device. In this configuration, the system is fastened such that the axis of the pivoting hinge is horizontal.

[0101] The transfer system according to the second embodiment may include two straight arms similar to the arms of system S1.

[0102] Advantageously, the chute is removably mounted on the hinged assembly, which allows for easy removal, cleaning, and sterilization, for example, in an autoclave. Easy cleaning is of particular concern because the chute comes into contact with various components during transport and requires careful cleaning.

[0103] Preferably, the inclined slot 14 is fastened to the hinge device 20 by quickly installing / removing the system R with one hand. Figure 8 ).

[0104] exist Figures 9A to 9C In the image, you can see an example of quickly installing / removing System R.

[0105] System R is positioned at rod 32, which is fastened to hinge device 20, and at rod 34, which is fastened to inclined groove 14. For example, rod 32 includes a housing 36 at its free end, the housing 36 being sized to accommodate the free end of rod 34. Housing 36 includes lateral walls 38 and a bottom 40. Lateral walls 38 include a notch 42 extending longitudinally over the thickness of housing 36. Figure 9C The notch 42 includes a flared insertion portion 42.1 leading to the free end of the rod 32 and a circular fixing portion 42.2.

[0106] The rod 34, which is fastened to the inclined slot, includes a transverse hole 44 that is open and accommodates an axial locking mechanism 46 that engages with a notch 42.

[0107] The locking mechanism 46 includes a locking lever 48, which is capable of lateral movement within the hole 44 and is pushed outward by means of a spring 50 that is compressed between the lever 48 and the lateral stop 52. In this example, the stop is formed by a bolt screwed into the hole.

[0108] The locking lever 48 includes three axial portions 48.1, 48.2, and 48.3, whose diameter decreases in the direction of the thrust applied by the spring.

[0109] The transverse hole 44 includes a shoulder 53, which mates with a shoulder 54 that connects the outer lateral surface of the axial portion 48.1 and the outer lateral surface of the axial portion 48.2. The diameter of the axial portion 48.2 is approximately equal to the diameter of the fixed portion 42.2.

[0110] The end of the locking lever 48 carries the actuation button 56.

[0111] The system operates as follows:

[0112] The operator presses the actuation button 56, thereby moving the locking lever 48 and compressing the spring 50, which then fits the portion 48.3 into the fixed portion 42.2 of the recess. The diameter of the portion 48.3 is smaller than the minimum lateral dimension of the recess 42, and the portion 48.3 can slide in the recess 42, which allows the end of the lever 34 to leave the housing 36 and to separate the groove from the hinge.

[0113] The inclined slot is repositioned onto the hinge by pressing the actuation button and inserting part 48.3 into notch 42.

[0114] This operation can be done with one hand.

[0115] The transfer system described in this specification is applicable to enclosures that include any type of sealing connection device, and these enclosures are not limited to those implementing bayonet connections.
