Device for centering closures and system with such a device

Abstract

The invention relates to a device (10) and a system (56) for closing containers (15) by means of closures.

Description

[0001] The invention relates to a device for placing a closure on a container and to a system comprising such a device.

[0002] The device is used in particular in filling and closing systems for automated aseptic filling and / or filling of toxic and / or highly potent active ingredients. The system is particularly such a system.

[0003] The system can process the containers as bulk goods or process RTU (Ready to Use) packaging in a nest.

[0004] When processing containers in bulk, the containers are fed into the system via a loading station. From the loading station, the containers are transferred, for example, to a turntable or conveyor belt. The containers are then separated during transport into the system. The containers are then transported individually through the system. This also includes containers that are fed in a tray. These are first removed from the tray and then transported individually through the system. Ideally, the separated containers are transported through the system in such a way that they do not touch any other containers.

[0005] When processing nested containers, the containers are transported through the system in a nest. It is possible that the containers are removed from the nest at individual stations. This can happen, for example, at the filling station. During transport to the next station, the containers are returned to the nest.

[0006] After the containers are filled, they are sealed at the closing station.

[0007] The containers within the meaning of the invention can be, for example, vials, carpules, or syringes. Suitable closures are used for each of the containers. In the case of syringes, a plunger stopper is inserted into the syringe for closure. In the case of carpules, a plunger stopper can be inserted into the carpule, or the carpule can be closed with an aluminum cap, which can, for example, include an integrated seal. To press the seal, the aluminum cap can be crimped or flanged. In the case of vials, the closure can be a plug that is inserted into the vial. The closure within the meaning of the invention can, however, also be an aluminum cap, which is used to create a secure sterile seal between the vial and the plug previously inserted into the vial. Such an aluminum cap typically also includes a plastic "flip-off" that covers the upper area of ​​the aluminum cap and can be removed once the aluminum cap is firmly connected to the vial (e.g., flanged).The aluminum cap typically has a radially inner free area covered by the flip-off. When the flip-off is removed, the plug underneath is accessible and can be pierced, for example, with a needle, without having to remove the plug or the aluminum cap. This allows fluid to be withdrawn with a cannula without opening the container.

[0008] A plug in this sense can be referred to as a primary closure, and the aluminum cap just described as a secondary closure. The primary closure in this sense directly closes an opening in the container. The secondary closure is placed over an already placed primary closure and can, for example, secure, fix, seal, provide additional protection, or similar. The closure in the sense of the present invention can be a primary closure or a secondary closure.

[0009] In the case of a vial, the aluminum cap is then crimped or flanged after it has been placed on the stopper to create a secure connection. For vials, the invention also allows for the vial to be sealed with a so-called press-on cap. With a press-on cap, the stopper is already integrated into the cap. The press-on cap is pressed onto the vial. Several locking fingers hold the press-on cap on the vial and seal it.

[0010] For all closure and container types, precise alignment of the container and closure is advantageous. Depending on the container and closure type, however, this may be absolutely necessary to enable the closure process at all. Especially with vials with aluminum caps, very precise positioning between the vial head and the aluminum cap is sometimes necessary.

[0011] For vials sealed with a stopper and aluminum cap, the stopper is inserted first. When processing individual vials, the stopper insertion usually takes place immediately after filling at a separate station. Since the stoppers usually have a chamfered insertion, allowing them to slide smoothly into the vial, the requirements for alignment accuracy are usually not too high. However, high positioning accuracy is also advantageous for this sealing process; the device according to the invention can be used for this purpose.

[0012] When processing vials in a nest, the stopper is also placed directly after filling.

[0013] After the stopper is in place, the aluminum cap (secondary closure) is placed on the vial with the already in place stopper (primary closure). For this purpose, the device according to the invention for placing the aluminum cap can be used in a pick-and-place process. The vial is precisely centered and the aluminum cap is placed on top. After the aluminum cap is placed on the vial, it is crimped or flanged.

[0014] To place the closure, it is first captured and placed in a receiving area of ​​the device. This is described in more detail below.

[0015] The device can be movable using a handling device or attached to a fixed station. After the closure has been detected, the device can be moved over the vial or container, for example, using the handling device. Alternatively, the container or vial can be moved underneath the device. The device is typically located in a closing station within a system.

[0016] The device according to the invention serves for the centered placement of a closure on a container. The device comprises a receiving area for receiving the closure to be placed and a pressing unit. The pressing unit is designed to press the closure onto the container in a pressing direction. The device can comprise a force sensor designed to detect a contact force with which the closure is pressed onto the container when applied to the container.

[0017] The receiving area is designed to receive the closure, for example to take it from a storage container and hold it until it has been placed on the container.

[0018] To ensure precise alignment of closure and container, the device has a centering device. The centering device is coupled to the pressing unit. The coupling is designed such that the centering device centers the closure and container when the closure is moved towards the container in the pressing direction by means of the pressing unit. During this centering, the centering device contacts the container and aligns the closure and container. The container can be moved and the pressing unit or the closure can remain stationary in the plane orthogonal to the pressing direction, or the device or the closure held in the receiving area can be moved, or the closure and container can move until both are precisely aligned in the desired position.

[0019] The pressing unit can be designed as a plunger that is arranged in the device so that it can move up and down along the pressing direction. The plunger can have a receiving area at one end for grasping and holding the closure.

[0020] In general, the receiving area can be arranged on the pressing unit and can be moved with it along the pressing direction.

[0021] The receiving area can be designed as a flat area, for example, at one end of the plunger, into which a vacuum channel opens. This allows the receiving area to be positioned close to and above a closure, such as an aluminum cap with a flip-off mechanism, and then be drawn into the receiving area by the vacuum from the vacuum channel and held there.

[0022] The centering device can comprise at least one contact finger coupled to the pressing unit via a guide rail. A guide rail mechanically ensures that the contact finger reliably performs a centering movement when actuated by a movement of the pressing unit.

[0023] The contact finger can be preloaded radially inward. The preload can be achieved by a spring. A coil spring, a leaf spring, or another spring can be used for this purpose. It is also conceivable for the contact finger to be preloaded radially inward pneumatically or hydraulically.

[0024] The device has, in particular, a plurality of contact fingers. In particular, the contact fingers can be arranged distributed in a circumferential direction around a position of the receiving area. The contact fingers can, in particular, be arranged concentrically to the position. The contact finger(s) have, in particular, contact sections provided for contacting the container. In particular, the contact sections for contacting the container are provided in a mouth section close to the opening. The contact section(s) can, in particular, be designed to be complementary to a region of the container to be contacted (in particular the mouth section). In particular, the contact sections can be designed in the shape of a circular segment in order to contact a round mouth section of a container evenly over its surface.It is particularly advantageous to contact the container at the mouth section, as, unlike contacting, for example, in the belly area or at the bottom, manufacturing tolerances, especially in the vial, can no longer lead to inaccuracies. If the mouth section is correctly aligned, the opening is correctly aligned and positioned.

[0025] The contact finger can be mounted in the device by means of a pivotable bearing so that it can pivot radially inward and outward. For example, when the closure or the receiving area holding the closure is lowered in the device, the contact finger can pivot radially inward toward a central axis, wherein the closure is lowered along the central axis in the direction of pressing. The receiving area can be arranged on a plunger forming the pressing unit, wherein the plunger forms a guide track along which a pickup element of the contact finger moves and follows the guide track.

[0026] The pressing unit has a section extending in the pressing direction, which has a tapered section, wherein the contour of the tapered section is designed as a link guide for an engagement element.

[0027] The pressing unit can generally comprise a guide slot into which a pickup element of the contact finger(s) engages to perform a centering movement when the closure moves within the device. The guide slot can be open on one side, and the contact finger(s) can be tensioned against the guide slot.

[0028] However, the guide rail can also be closed and form a forced guide for the respective pickup element of a contact finger.

[0029] As already mentioned, the device can be designed to suck the closure into the receiving area using negative pressure and to accommodate it in the receiving area. The pressing unit can comprise a negative pressure channel that extends into the receiving area to provide a negative pressure for sucking a closure into the receiving area. This allows closures to be accommodated in the receiving area in a particularly simple manner.

[0030] When suction is carried out using negative pressure, it can be provided that the receiving area does not specify a precise position for the closure, but that a slightly eccentric receiving of the closure is also possible. In this case, the centering device, in particular a plurality of contact fingers of the centering device, can be designed and arranged such that they effect position control of the closure when the closure is moved into a retracted position, for example by retracting the plunger at the end of which the receiving area is arranged. The centering device or its contact fingers can form a through-opening with a cross-section designed such that only closures that are arranged approximately in a desired position in the receiving area can pass through it. If a closure is arranged too far from the desired position in the receiving area, it is centered by the centering device orwhose contact finger is detached, falls off and a new closure must be grasped, picked up and held. When the closure is moved further back into the device, it can be provided that the centering device or its contact fingers contact the closure laterally and align it centrally. In particular, it can be provided that the receptacle is moved back into the device by means of the plunger after a closure has been picked up and when the closure has passed the centering device or its contact finger without being detached, that the receptacle is moved back further and the centering device, e.g. by pivoting its contact fingers radially inwards, contacts the closure laterally at several points around the circumference and centers it in the receiving area. When the closure or the receiving area is then moved out, the closure is then centered in the receiving area, e.g. in the middle of the plunger.

[0031] The device can comprise a pressure or flow sensor configured to detect the pressure or flow in the vacuum channel to monitor the suction process of a closure. If, for example, a closure is tilted and not correctly positioned in the receiving area, sufficient negative pressure cannot be built up in the vacuum channel, and the error can be detected. Likewise, a defective closure or a dropped closure can be detected. Even if a closure falls off because it is not correctly positioned, this can be detected.

[0032] However, the receiving area can also operate without negative pressure. This is particularly useful for filling toxic and / or highly potent active ingredients, as no purification of the extracted air is required. For this purpose, the receiving area can be designed to clamp and hold a closure. This clamp and hold can be used instead of negative pressure or to support such a suction.

[0033] The pressing unit can comprise an ejector, which can eject a closure held in the receiving area by means of a relative movement between the receiving area and the ejector along the pressing direction. In a basic position, the ejector can release the receiving area, so that a closure can be received in the receiving area by pressing the receiving area onto the closure and can be held there in a clamped manner.

[0034] For this purpose, the receiving area can in particular comprise clamping elements, for example clamping jaws or clamping fingers, in order to clamp and hold a closure.

[0035] The device can comprise a gassing channel designed to direct a gas into the area around an opening of the container to be sealed. The container can thus be sealed under the desired atmosphere. For this purpose, the gassing channel can open into the area of ​​the device around a position of the receiving area during the sealing of the container. Thus, a desired atmosphere can be created locally in this area by introducing gas.

[0036] As already explained, part of the present invention is also a system for closing containers using closures, wherein the system comprises a device as described above and / or below in a closing station. The system can be designed to close individual containers with closures in the closing station, or the system can be designed to feed the containers in a tray to the closing station and close the containers in the tray.

[0037] The system can be designed in such a way that the centering device contacts a respective container at a mouth section which merges into an opening of the container during centering in order to center the container.

[0038] System according to the preceding claim, characterized in that the system is designed such that the centering device moves the container during centering so that it is centered under the device arranged stationary in the closing station.

[0039] Further features and advantages of the invention are the subject of the following description and the drawings of embodiments of the device.

[0041] The following explanation of embodiments is to be understood as examples and the features of the embodiments are partly optional without this being pointed out separately again.

[0042] Fig. 1 shows a device 10 for centering a closure 12 onto a container 15.

[0043] The container 15, which is designed as a vial in this case, is in Fig. 1 and comprises a receptacle 22 and a plug 24. The plug 24 forms a primary closure, which closes the opening of the receptacle 22, but the container 15 must still be closed with the closure 12, which forms a secondary closure. The secondary closure can be as in the example of Fig. 1 in particular an aluminum cap 14 with “flip-off” 13.

[0044] The device 10 according to the invention comprises a receiving area 16. The receiving area 16 is designed to receive the closure 12 to be placed. The device 10 can, in the sense of a pick and place mechanism, pick up a closure 12 from a template and hold (receive) it in the receiving area 16 and make it available for closing a container. This receiving is in Fig. 1. Here, the receiving area 16 is in an extended state and protrudes from the outline of the device 10, in particular from a housing sleeve 17. The receiving can be carried out in various ways, for example by means of negative pressure, as with reference to the device in Fig. 1 will be explained in more detail. Alternatively, or in support of this, the receiving area can also be gripped by means of a clamping action. Clamping elements are typically provided for this purpose. Within the meaning of the invention, it is also provided that the gripping and holding by means of the receiving area is achieved by an adhesive, microstructured polymer. The polymer can, for example, be formed as a coating in the receiving area 16.

[0045] The device 10 according to the invention further comprises a pressing unit 18. The pressing unit 18 is designed to press the closure 12 along a pressing direction 20 onto the container 15. In Fig. 2, the device 10 with closure 12, which is located in the receiving area 16, is shown during retraction. In Fig. 3, the device 10 is shown placed over the container 15 with the closure 12 retracted. Fig. 4 to 6 show the subsequent lowering and pressing of the closure 12.

[0046] The device 10 comprises in the example of Fig. 1 includes a force sensor 50. The force sensor 50 is designed to detect the contact force with which the closure 12 is pressed onto the container 15 when it is applied to the latter. The detected force can, for example, serve as a termination criterion for aborting the pressing process. Based on the force developed during pressing, any misalignment can also be detected.

[0047] The device 10 comprises a centering device 28. The centering device 28 serves to ensure that the container 15 and the closure 12 are correctly aligned with one another when the closure 12 is placed on the container. For this purpose, the centering device 28 is coupled to the pressing unit 18. The coupling is designed such that the centering device 28 centers the closure 12 and the container 15 with respect to one another when the closure 12 is moved toward the container 15 in the pressing direction 20 by means of the pressing unit 18. During this centering, the centering device 28 contacts the container 15 and aligns the closure 12 and the container 15 with respect to one another.

[0048] The coupling is in the embodiment according to Fig. 1 is realized by means of a link guide 29.

[0049] For this purpose, the pressing unit 18 comprises a plunger 19, which is arranged in the device 10 so as to be movable up and down along the pressing direction 20. The plunger 19 of the pressing unit 18 comprises a shaft 26 extending in the pressing direction 20. This shaft 26 has a tapered section 27. The contour of the tapered section 27 serves as the slotted guide 29. The centering device 28, in turn, has contact fingers 30, each of which has an engagement element 32 in the form of a roller 32. The contact fingers 30 are mounted in the device 10 so as to be pivotable radially inward and outward by means of a pivotable bearing 36. The contact fingers 30 are preloaded in the radially inward direction 40 by means of a respective spring 34. As a result, the roller 32 follows the contour of the shaft 26 and when the plunger 19 moves up and down, the fingers move radially inwards as the roller rolls along the tapered section 27 see Fig. 4. If the plunger 19 is then moved further downwards, the contact fingers 30 move radially outwards again, see Fig. 5. With the radially inward movement, the container 15 is aligned exactly under the closure 12. With the Fig. 5, the closure 12 is finally pressed onto the container.

[0050] During the described movement of the receiving area 16 in the device 10 by means of the pressing unit 18 on which it is arranged and with which it is movable, the closure 12 is held in the receiving area 16 by means of negative pressure. This negative pressure is provided via the negative pressure channel 42 in the receiving area 16.

[0051] The device 10, as in Fig. 1 is designed accordingly to suck in the closure 12 using negative pressure and to receive it in the receiving area 16. For this purpose, the shaft 26 of the plunger 19 of the pressing unit 18 has the vacuum channel 42 in its center, which extends into the receiving area 16 to provide a vacuum for sucking a closure 12 into the receiving area. The device 10 further comprises a pressure or flow sensor 52, which is designed to detect the pressure or flow in the vacuum channel 42 (both types of sensors are possible) in order to check the suction process of a closure 12.

[0052] When suction is carried out using negative pressure, as in the example of Fig. 1, it can be provided that the receiving area 16 does not specify an exact position of the closure 12, but also a slightly eccentric receiving of the closure 12 is possible. In the example of Fig. 1, for example, the end of the plunger 19 is designed as a flat surface into which the vacuum channel 42 opens and can suck a closure 12 against the flat surface of the end of the plunger 19. This allows the closure 12 to be held in the receiving area 16 without jamming and, in particular, to be adjusted in its position in the receiving area 16.

[0053] The centering device 28, in particular a plurality of contact fingers 30 of the centering device 28, can be designed and arranged such that they effect a position control of the closure 12 when the closure is moved into a retracted position, for example by retracting the plunger 19, at the end of which the receiving area 16 is arranged. The centering device 28 or its contact fingers 30 can have a through opening 58 (marked by a double arrow in Fig. 1) with a cross-section designed such that only closures 12 that are arranged approximately in a desired position in the receiving area 16 can pass through it. If a closure 12 is arranged too far from the desired position in the receiving area 16, it is detached by the centering device 28 or its contact finger 30, falls off, and a new closure 12 must be detected, picked up, and held.

[0054] When the closure is moved further back into the device 10, as shown in Fig. 2, it can be provided that the centering device 28 or its contact fingers 30 contact the closure 12 laterally and align it in a centered manner. In particular, it can be provided that the receptacle 16 is moved back into the device 10 by means of the plunger 19 after picking up a closure 12 and when the closure 12 has passed the centering device 28 or its contact fingers 30 without being detached, that the receptacle 16 is moved back further and the centering device 28, e.g. by radially inward pivoting of its contact fingers 30, contacts the closure 12 circumferentially at several points with its contact surfaces 38 and centers it in the receiving area 16. When the closure 12 or the receiving area 16 is subsequently moved out, the closure 12 is then centered in the receiving area 16, e.g. centrally on the plunger 19.

[0055] Thus, first the closure 12 is arranged centrally on the plunger 19 and, as described above, when the closure 12 is moved out, the container 15 is aligned and centered with respect to the plunger 19.

[0056] The receiving area 16 can also be designed to clamp and hold a closure 12. This is shown in Fig. 9. In order to eject the closure from the receiving area 16, the pressing unit 18 in this example comprises an ejector 44, which, by means of a relative movement between the receiving area 16 and the ejector 44 along the pressing direction 20, causes the closure 12 held in the receiving area 16 to be ejected. In a basic position, the ejector 44 releases the receiving area 16, so that a respective closure 12 can be received in the receiving area 16 by pressing the receiving area 16 onto a closure 12 and can be held there in a clamped manner.

[0057] As in Fig. 7 and Fig. As shown in Figure 8, the device 10 can comprise a gassing device 45 with a gassing channel 46 designed to direct a gas into the area around an opening of the container 15 to be sealed, in order to be able to seal the container 15 under the desired atmosphere. For this purpose, the gassing channel 46 opens into the area of ​​the device 10 around a position of the receiving area 16 when closing the container 15.

[0058] The invention also includes a system 56 for closing containers 15 by means of closures 12, as in Fig. 10. The system 56 comprises a sealing station 60 in which a device 10 as described here, for example according to Fig. 1 or Fig. 8 or Fig.9. The system 56 is designed to transport and separate containers along a transport direction 57 and then close them with an aluminum cap 14, which forms a closure 12 in the sense of the invention.

[0059] The system 56 is designed such that the centering device 28 of the device 10 moves the respective container 15 during centering, so that it is centered under the device 10 arranged stationary in the closing station 60.
