Definitions
- the present invention relates to a coupling element and a docking device containing a coupling element. Furthermore, the invention relates to a holding device for actuating coupling elements or docking devices according to the invention and a connecting device containing at least two coupling elements according to the invention.
- containers are filled using double-cap technology, which have proven to be very efficient, but also, due to the technical design and the materials used, have proven to be expensive.
- a generic, sealed docking device between environmentally insulated containers which has a rigid, annular flange with a door.
- the flange and the door are preferably made of a hard plastic material.
- the containers which can be in the form of sacks, preferably consist of a soft plastic material.
- a disadvantage of this docking device is the structurally very complex processing of the flange with its locking cam mechanism, which increases the manufacturing costs for a disposable item inappropriately and is also user-unfriendly because it is unwieldy.
- Docking devices for contamination-free decanting are used in particular when handling radioactive materials and regularly require a lock arrangement with complex construction, e.g. DE 39 05 362 AI can be seen.
- a docking device adapted to its geometry is required for each container type.
- DE 695 04 581 T2 shows a sealed docking device between two environmentally insulated housings, each of which is provided with a door.
- the outer sides of the doors can be brought into tight contact with one another, the locking mechanism of the first door also being able to be controlled by an actuating device of the second door.
- the unit consisting of two doors is brought back into place in the respective receptacles or bearings provided for this purpose, and the two housings can be separated from one another. In this way, the outer sides of the two doors remain free of contamination, as they have been isolated from each other during the transfer.
- the docking device according to DE 695 04 581 T2 is also structurally complex and cannot easily be applied to environmentally insulated filling mechanisms for smaller structures.
- Docking devices of simpler design can also be formed according to DE 196 24 189 AI from a first docking element, which is funnel-shaped, and a second docking element, which is form-fitting to the funnel-shaped docking element, in particular with the formation of a spherical contact surface.
- the contact surface must have a rubber-elastic surface.
- DE 43 29 276 AI proposes a dust-proof connection of transportable bulk containers, which in turn are already provided with a connection device.
- the bulk goods container In the docked state, the bulk goods container is let into an elastic disc with the outlet from above and, when closed, is closed by a closing cone.
- the outlet hopper of the bulk goods container has a diameter that is larger than that of the hole in the rubber washer.
- a bottom cone in the discharge funnel cuts off the bulk material flow with its lower edge.
- DE 20 217 669 UI describes a sealed docking device between two essentially environmentally insulated containers, each container being essentially flexible, at least in some areas, and being able to be tightly connected to a coupling element.
- the elastic coupling elements lying tightly against one another are each with a Equipped slot that can be opened by elastic deformation of the coupling elements. Since the respective slots of the coupling elements which lie flush against one another lie precisely one above the other, the slots are opened and pressurized goods are conveyed by pressurizing opposite sides of the coupling elements. In this way, in particular the handling compared to docking devices, as are known from DE 69 504 581 T2, is to be simplified and the manufacturing costs are reduced.
- WO 03/037756 is concerned with a multi-walled reversing container comprising an inner and an outer shell.
- the space between the flexible inner container and the outer shell can be filled with compressed air via a compressed air supply line, so that the cross section of the inner flexible container wall can be adjusted to reduce the falling speed of the bulk material introduced via an upper inlet. In this way, gentle filling with bulk goods is possible, since the drop distance and the falling speed of the bulk goods can be influenced.
- the pressurization of the space between the inner and outer shells can be used to quickly and efficiently remove even the last remaining bulk goods when emptying the container.
- WO 03/037756 discloses a container which is equipped at its inlet and / or outlet with an elastic coupling element, comprising a slot opening.
- Such a coupling element can, for example, have guide rails attached to its circumferential edge on its longitudinal sides and can be equipped on its opposite narrow sides with fixing elements for mutual fixing of the coupling elements forming a docking device.
- Coupling elements of this type are suitable for axial coupling to a second coupling element for the purpose of forming the docking device described above.
- GB 2 040 862 A discloses a packaging device for vacuum packaging or for packaging in the absence of air and moisture.
- holding and clamping members are also provided, with which the opening edge of a flexible container can be held and automatically opened or closed during filling.
- a one-piece holding device made of a rubber material can also be used, which, in order to ensure reliable opening and closing of the opening edge of the flexible container, is additionally equipped with metallic struts.
- the object of the present invention is therefore to further develop sealed docking devices of this type and coupling elements forming these docking devices and the known methods for the environmentally insulated filling of containers with bulk material or fluids in such a way that the disadvantages of the prior art of technology are overcome and that in particular the handling is simplified and the manufacturing costs are simplified be reduced.

- the coupling element according to the invention is or are opened by pressing the first and second joint bodies against one another and / or by pulling the first and second closure strips apart, the resilient cheek body or the resilient partial regions of the same ensuring reversible, secure closing.
- first and / or second bearing element of the first and / or second closure strip at least partially reproduce or emulate the shape of a circular ring, in particular represent web arms.
- First and second bearing elements are preferably designed in such a way that they form a joint body which is held via a common axis and / or via a common joint cap in such a way that guided, hinge-like movement of the cheek bodies connected to the bearing elements is made possible.
- a rounded or circular outer and / or inner surface of the bearing elements generally enables a simple way a joint guide.
- adjacent bearing elements and / or the outer and / or inner surfaces of the joint bodies can be provided with a lubricant and / or lubricant.
- the first and / or second bearing element of the first and / or second closure strip is attached or can be attached to the outside of the first and / or second end of the cheek body of the first and / or second closure strip.
- the cheek body is given the greatest possible freedom of movement over its entire length.
- this embodiment e.g. includes such coupling elements in which the bearing element or elements are an integral part of the first and / or second sealing strip, as well as those in which the bearing element or elements are separate components connected to the sealing strip or the webs or cheeks of the sealing strip are reversibly connectable.
- a bearing element can be coupled to the locking bar via a snap-in connection, a tongue and groove connection or another reversibly releasable non-positive or positive connection.
- This enables the coupling elements according to the invention to be handled very simply and, moreover, allows containers to be kept closed with the aid of the closure strips without having to rely on additional bearing elements.
- a separate cover rail can be used, which can be pulled over adjacent first and second closure strips, e.g. with the help of a tongue and groove connection.
- the number of bearing elements required for filling or decanting which are structurally complex and accordingly more expensive, can be greatly reduced in this way without having to accept restrictions when filling and decanting bulk goods.
- the, in particular annular, first and / or second bearing element does not extend or extend to the inside of the cheek body of the first or second closure strip, in particular has a central angle in the range from 90 ° to 240 ° or exhibit. Since the bearing elements do not circumscribe a complete circular path, but rather leave an opening in the area of the inside of the cheek body, the handling when joining the closure strips becomes coupling. tion elements or docking devices and in particular also the attachment of bag edges to the closure strips facilitated.
- a further embodiment is characterized in that the first and / or second joint cap has or have internal dimensions which essentially correspond to the external dimensions of adjacent first and / or second bearing elements, so that the cheek bodies of the first and second closure strips are in contact with one another on the inside the first joint cap encloses the first and second bearing element of the first and second closure strip and the second joint cap the second and first bearing element of the first and second closure strip at least partially flush, forming a pivot bearing.
- the forces to be used for bending the elastic cheek bodies apart can be introduced into the closure strips, for example, by using a joint cap. This joint cap keeps the first and second bearing elements forming the joint body in their predetermined adjacent arrangement even when the cheek bodies are opened and closed.
- first and / or second joint cap comprises an articulated cap cover with an articulated axis, in particular in the form of a hollow cylinder segment, which extends into the first inner space or first locking bar formed by the first and second bearing element the second inner space formed by the second and the first bearing element by the first and second closure strips can be inserted.
- a joint or axis of rotation can also be introduced into these first and second bearing elements or the first and second interior spaces.

It has proven to be particularly advantageous to have the cheek bodies end approximately at the center of first and second interior spaces formed by the first and second bearing elements. On the one hand, this minimizes the mechanical stress on the components of the coupling element. On the other hand, the edges of the bags attached to the cheek bodies are treated very gently and do not experience any distortion when opening and closing the coupling element.
- first bearing element of the first and / or second sealing strip comprises at least sections of at least one annular body and that the second bearing element of the first and / or second sealing strip comprises at least two spaced-apart annular bodies

- the inner sides close an opening slot when they are in mutual contact. If a coupling element according to the invention is formed from two cheek bodies, each of which is curved on the inside, this initially leads to the fact that, in the case of fixed bearing elements or joint bodies, the inner sides of these cheek bodies which abut one another form a substantially straight closure line form.
- the bulging of the inner sides in the basic state in the case of such a coupling element already provides a pretension and consequently an even more secure closure.
- the use of bulging cheek bodies on the inside in a coupling element according to the invention means that the outside of these cheek bodies often have an external curvature in such a coupling element. This outer curvature is now suitable for guiding or facilitating the separation or opening of the cheek bodies which are in contact with one another.
- At least one outer side of a cheek body has an outer curvature when the inner sides of the cheek members of the first and second closure strips are in contact, in particular flush.
- Coupling elements in which the inside of at least one cheek body is profiled are also particularly preferred. By profiling the inside of the cheek body, both the tightness of the coupling elements can be further improved and the risk of residual contamination, e.g. by remaining bulk goods in the area of the coupling element, can be considerably reduced.
- preferred coupling elements have at least one bulge and / or at least one indentation groove on the inside of the cheek body of the first and / or second closure strip, which extends in particular from the first to the opposite second end of the cheek body, preferably parallel to the longitudinal axis of the Cheek body, extends or extend.

- the flexible containers or hoses are then preferably not attached to these elastic areas by means of an adhesive, but rather only in areas which are not essential for secure closure of the cheek bodies. In this way it is prevented that the permanent elasticity of the above-mentioned areas of the inner wall used for the secure closure is affected by adhesives or adhesives.
- a particularly preferred coupling element has a flexible container or a flexible hose, which or, in particular along the edge regions or longitudinal edges, on the inside, outside, top edge and / or bottom edge of the cheek body of the first and / or second closure strip, in particular along the entire length of the cheek body, can be attached or is present.

- peelable adhesive strips are also used, which can be removed after use and replaced with a new adhesive strip.
- the first and the second sealing strip essentially match in their shape and / or size.
- a particular advantage of the coupling elements according to the invention is that they can be formed from two essentially identical sealing strips. For this purpose, one of the sealing strips should only be rotated by 180 ° C. in order to be able to be brought into contact with a further sealing strip, forming a coupling element. This reduces the manufacturing costs, simplifies assembly and ultimately also reduces the number of outage sides when filling or decanting bulk goods.

- the coupling element 1 according to the invention can, as shown in FIG. 1b), be obtained by placing a first Nerschl withance 2 with a second Nerschl withang 4, which may be essentially identical to the Nerschlußance 2, along the inside of their cheek bodies 6 and 8 become.
- the first end 44 of the cheek body 6 of the first closure strip 2 comes into contact with the second end of the cheek body of the second closure strip 4 and the second end of the cheek body of the first closure strip 2 with the first end of the cheek body of the second closure strip 4, and the bridge arm 38 the first locking bar 2 engages in a first bearing element 22 of the second locking bar 4, comprising spaced web arms 34 'and 36 ", and a web arm 38' of the second locking bar 4 engages in the first bearing element 18, comprising the web arms 34 and 36, with the formation of
- the inner walls 10 and 12 of the cheek bodies 6 and 8 of the first and second closure strips 2 and 4 come into contact via their bulge webs 42a, 42b and 42'a and 42'b second bearing elements 18, 20, 22, 24 of the first and second closure strips 2, 4 each flush to form the first and nd second joint bodies 25, 25 'one above the other, due to the elastic properties of the cheek bodies 6 and 8 and the rounded design of the inner walls 10 and 12, this leads to a slightly rounded outer curvature of the
- FIG. 2 shows a first closure strip 2 of a coupling element 1 according to the invention in a schematic side view.
- the shoulders 26 and 28 of the first and second bearing elements 18, 20 begin at opposite ends of the outer wall 14 of the cheek body 6.
- At least the inner wall region 10 settles into the center of the through the web arms 34, 36 and 38 partially enclosed cavities 48 and 50 continued.
- the cheek body 6 is made from two different segments, namely an outer wall area 14 and an inner wall area 10 directly adjoining this, which has a slight curvature.
- the web arms 34, 36, 38 cover viewed from the side approximately a circular ring of 250 to 300 °.
- the bridge arms can extend to this point the inner wall of the sealing strip can be brought up so that it is still possible to apply a second sealing strip, as described above, to the first sealing strip to form a coupling element according to the invention.
- FIG. 3 illustrates a first joint cap half 60 with an outer wall 62, a cut inner hollow cylinder 64 and a joint cap cover 66, which together describe at least part of a receiving space 68 for first and second bearing elements.
- the joint cap half 60 can be placed on the first and / or second bearing elements of mutually placed first and second closure strips 2 and 4 in order to create a rotary body or an axis of rotation.
- the cut inner cylinder 64 is designed such that, if necessary, the first or second end of the cheek body protruding into the cavity 48 or 50 can also be accommodated.
- the cut inner cylinder 64 is preferably dimensioned such that it can be inserted, in particular flush, into the spaces 40 and 50 formed by the bearing elements and partially enclosed.
- the inside of the outer wall 62 corresponds in size and shape, in particular flush, to the outer contour of the first and second bearing elements of the first and second closure strips.
- the second joint cap half 70 shown in FIG. 4 forms with the first joint cap half 60 a joint cap 56 which essentially completely surrounds the adjacent, intermeshing first and second bearing elements, which together form a joint body 25, except for the area circumscribed by the opening angle 58.
- the outer wall 72 of the second joint cap half 70 is designed in such a way that a first wall region 86 can be pushed in along the inside of the outer wall 62 of the first joint cap half 60, so that an externally closed and not easily separable joint cap 56 with a substantially uniform outer surface is obtained becomes.
- the second joint cap half 70 also has a partially cut inner cylinder 74 which projects into the partially enclosed spaces of the first and second bearing elements.
- the second articulated cap half 70 also has a locking opening 80, a suction opening and a further locking bolt 84.
- the locking pin 52 des Bridge arm 38 of the second bearing element 20.
- By dimensioning the locking opening 80 is ultimately also limited the freedom of movement of the bearing element 20 which is rotatably mounted in the joint cap 56.
- An overuse of the cheek cap 6 or 8 due to an excessive opening of the coupling element is prevented in this way.
- the locking bolt 84 on the inside of the joint cap cover 76 helps to limit the deflection of the first and second closure strips and the freedom of movement of the joint cap 56 as such.
- the locking bolt 84 engages in the recess 59 of the lower arm 36 of the first bearing element 18.
- the combination of the locking pin 52 / locking opening 80 system on the one hand with the locking bolt 84 / indentation 59 system ensures a permanently reliable relative movement of interlocking bearing elements and in particular also ensures that the joint caps 60, 70 are centered relative to the locking strips 2 and 4.
- Figure 5 shows two coupling elements 1 and 1 'according to the invention in a side view.
- the first and second bearing elements of the first and second closure strips are each surrounded by the first and second joint cap halves 60 and 70 to form the joint cap 56.
- the inner walls 10 and 12 of the cheek bodies of the first and second sealing strips are pressed against one another in the basic state, so that the bag 90 is completely closed. This is due, on the one hand, to the inner walls of the cheek bodies 6 and 8, which are arched in the basic state and which, when adjacent bearing elements are fixed in the joint caps 56, 56 'at the two ends of the closure strips, form an essentially rectilinear closure slot for mutual contact.
- the bulge webs on the arched inner walls further reinforce this effect.
- the edge regions of the flexible bag 90 are fastened in the region of the inner walls 10 and 12 of the cheek bodies 6 and 8, it having turned out to be particularly advantageous to extend this fastening to the opposite first and second ends of the cheek bodies , so that the point at which the edge of the bag reverses its direction essentially coincides with the pivot point of the cheek body when opening and closing the closure strips. In this way, the bag is not, or at least, stressed when the coupling element is opened and closed, as a result of which material fatigue or cracks, which could lead to contamination of the surroundings, are avoided.
- the edge of the flexible bag 90 is preferably in the area of the edge of the cheek body 6 and 8, ie in the transition area from the inner wall to the outer wall.
- This type of attachment has the advantage that the bag wall lies against the bulge webs 42a and 42b, but since adhesive material is not used in the entire remaining inner wall areas, the elastic properties of the inner wall are permanently retained. Accordingly, secure locking (not shown) is ensured via the bulge webs 42a and 42'a or 42b and 42'b that have come into contact with one another in the coupling element 1 according to the invention.
- the opening angle 58 of the joint cap 56 defines the freedom of movement of the first and second closure strips. If the opposing joint caps of a coupling element are pressed against one another, the first and second closure strips move away from one another while opening the bag.
- the maximum spread of the closure strips is defined by the opening angle 58 of the joint caps 56. Because as soon as the outer sides of the first and second closure strips of a coupling element abut the edges of the joint cap that define the opening angle 58, further opening is no longer possible without destruction.
- the system of locking pin 52 and locking opening 80 and the system of indentation 59 and locking bolt 84 also contribute to limiting the opening angle.
- a flexible transfer hose 94 can also be attached to the coupling element 1 ', for example.
- the coupling elements 1 and 1 ' are dimensioned essentially identically and, when coupled to one another, form a docking device 96 according to the invention.
- FIG. 6a shows a cross-sectional representation of a particularly preferred cheek body 6 of a coupling element 1 according to the invention.
- a substantially elastic, protruding web 120 is provided in this embodiment along a central longitudinal axis of the cheek body.
- Indentations 122 and 124 extend to both sides of this central elastic web 120, to which, in turn, raised side edge regions 126 and 128 are connected on both sides.
- the edge of the flexible bag is connected to the inner wall of the cheek body only at one point allows the bag edge the greatest possible freedom of movement, thereby reducing tensions, tears or material wear on the bag.
- the increased freedom of movement of the edge of the bag in connection with the indentations 122 and 124 also help to be able to close the coupling element again in an environmentally-friendly manner even if bulk material residues have remained in the area between adjacent cheek bodies of the coupling element. Since the bag is only attached at one point, these residues can be pressed into the indentations and do not interfere with a tight closure of the coupling element via the protruding elastic web 120.
- a coupling element that has first and second closure strips with cheek bodies, as shown in FIG. 6a), is particularly preferred.
- FIG. 6 b) shows a perspective partial view of a cheek body according to FIG. 6 a), but without also depicting the flexible bag 90.
- 6b) shows the indentations 122 and 126 which extend over the inner sides of the cheek body 6, the raised side edge regions 126 and 128 and a centrally extending elastic web 120.
- FIG. 6b) shows a spring element 114a on the upper side or upper edge of the cheek body 6 and a groove 92a along the underside 17 of the cheek body 6 of the closure strip 2.
- FIG. 7 shows a holding device 100 according to the invention with a first receiving unit 102 and a second receiving unit 104 as well as lever arms 106 and 108.
- Units 102 and 104 are designed such that they can accommodate the joint caps 56, 56 'of the coupling elements 1 and 1' at least partially flush. At least sections of the receiving unit and joint cap preferably behave like negative and positive fits.
- the coupling element 1 ' is already inserted into the holding device 100, the transfer hose 94 being connected to a container 116 which is to be filled. As already described for FIG. 5, the coupling element 1 has spring elements 114a and 114b on the upper side of the closure strips or cheek bodies.
- the coupling element 1 on the undersides of the closure strips or cheek body grooves 92a and 92b for receiving the spring elements of the coupling element 1 ' is held on its underside via base plates 110 in the receiving units 102 and 104.
- the upper holding plates 112 can, as shown in FIG. 8, be guided over the upper sides of the joint caps 56 and fastened, for example by means of screws.
- the receiving units 102 and 104 are dimensioned such that the springs 114a, 114b and grooves 92a, 92b are moved into one another as far as possible by fastening or screwing on the upper holding plate 112.
- an absolutely environmentally insulated docking device 96 is obtained, with which any bulk goods, as shown, for example, in FIG. 9, can be transferred into stationary or transportable containers 116.
- the lever arms 106 and 108 are actuated in such a way that the first and second receiving units 102 and 104 are moved towards one another.
- the first and second closure strips of the first and second coupling elements move away from each other uniformly, opening both the flexible bag 90 and the flexible transfer hose 94.
- the docking device according to the invention can continue to be used without contamination, without the need for additional cleaning steps.
- the removal of the docking device according to the invention from the holding device 100 is as simple as its installation.
- 10a shows a pneumatically driven holding device 100 with a first receiving unit 102 and a second receiving unit 104.
- the pneumatically driven holding device 100 has a pneumatic actuator 130, with which Pneumatic cylinders 132 and 134 allow the receiving units 102 and 104 to be moved towards and away from one another by opening or closing the docking device.
- the extent of the opening and thus also the decanting speed can be set very precisely. It is also an advantage that coupling elements with very rigid stiffening strips, which, when pre-stressed, as described above, guarantee a high level of environmental tightness, can nevertheless be easily opened and closed. It can be provided that the pneumatic cylinders 132, 134 move the receiving unit 102 and 104 towards or away from one another via a releasable coupling 136. As is also shown in FIG. 10 b), the coupling 136 can be locked in a receiving unit via two, for example pneumatically controlled, pins. With the aid of a pneumatically driven holding device 100, a filling or decanting process can be automated very easily using the coupling elements or docking devices according to the invention.
