DETAILED DESCRIPTION

(13) Exemplary embodiments are described below with reference to the figures. Here, elements in the various figures which are identical, similar or act in the same way are provided with identical reference signs, and in some cases a repeated description of these elements is omitted in order to avoid redundancy.

(14) FIG. 1 shows schematically a plan view of a closing device 100 for closing a filled container with a container closure, in the present case a bottle without a support ring with a screw closure or, alternatively, a press-on closure. FIG. 2 shows schematically a sectional view through the closing device 100 from FIG. 1. The closing device 100 is an example of a container handling device. It is of rotary construction. Accordingly, it comprises a handling carousel 102, which can be rotated about a central axis of rotation 101 and on the circumference of which a plurality of closing members 103 for the application of a container closure to a filled container is arranged in a uniformly distributed manner. Each closing member 103 is assigned a device 1 for holding a container. In each of FIGS. 1 and 2, by way of example, only two of the multiplicity of closing members 103 and devices 1 are shown.

(15) FIGS. 3 to 5 each show schematically a perspective side view of the device 1 for holding a container 105 in the closing device 100 from FIGS. 1 and 2.

(16) The device 1 comprises a carrier 2 and a first holding arm 4 and second holding arm 6, arranged on the carrier 2, for holding the container 105. The first holding arm 4 and the second holding arm 6 are arranged on the carrier 2 in such a way that they can be moved between an open position for receiving and releasing the container 105 and a closed position for holding the container 105.

(17) FIG. 3 shows the device 1 with holding arms 4, 6 in the closed position. FIG. 5 shows the open position of the holding arms 4, 6. FIG. 4 shows a position of the holding arms 4, 6 in a state during the movement of the holding arms 4, 6 from the closed position according to FIG. 3 into the open position according to FIG. 5, which is referred to below as the intermediate position.

(18) In the closed position, the holding arms 4, 6 define a holding plane 8 on which a retaining ring, to be more precise a lower surface of the retaining ring, of a held container 105 rests in the closed position. According to this embodiment, the holding plane 8 is oriented horizontally, i.e. perpendicular to the direction of gravity.

(19) The first holding arm 4 and the second holding arm 6 can each be pivoted about a pivoting axis 10 between the open position and the closed position and rotated about a rotation axis 12 oriented transversely to the pivoting axis 10 and arranged perpendicularly to the holding plane 8. According to this optional embodiment, the pivoting axis 10 and the rotation axis 12 are oriented orthogonally with respect to one another, and the pivoting axes 10 are oriented parallel to the holding plane 8.

(20) In the closed position of the holding arms 4, 6, which is shown in FIG. 3, the pivoting axes 10 are oriented parallel to one another. As an alternative, however, they can also have some other orientation with respect to one another in the closed position.

(21) The device 1 is configured in such a way that, during movement of the holding arms out of the closed position into the open position, the holding arms 4, 6 undergo exclusively a pivoting motion about their respective pivoting axis 10 in a first motion segment, more specifically by a predetermined pivoting angle. The pivoting angle is optionally predetermined as 30 (=/6 rad) but can also have some other value, e.g. 10, 20, 45 or 60.

(22) The device can be configured in such a way that the predetermined pivoting angle can be changed, e.g. by means of a modified setting that can be performed in a conversion process.

(23) The first motion segment corresponds to a movement of the holding arms 4, 6 out of the closed position shown in FIG. 3 into the intermediate position shown in FIG. 4.

(24) Following the first motion segment, the holding arms 4, 6 undergo exclusively a rotary motion about their rotation axis 12 in a further motion segment, which corresponds to the movement of the holding arms 4, 6 out of the intermediate position shown in FIG. 4 into the open position shown in FIG. 5.

(25) Conversely, in an analogous sequence according to this optional embodiment, starting from the open position and moving into the closed position, the holding arms 4, 6 undergo exclusively a rotary motion about their rotation axis 12 out of the open position into the intermediate position in the further motion segment, and then undergo exclusively a pivoting motion about their pivoting axis 10 in the subsequent first motion segment.

(26) Alternatively, the holding arms 4, 6 may also undergo exclusively a rotary motion about their rotation axis 12 in the first motion segment, or a combined motion composed of a pivoting motion about their pivoting axis 10 and a rotary motion about their rotation axis 12.

(27) Furthermore, the holding arms 4, 6 may also undergo exclusively a (further) pivoting motion about their pivoting axis 10 in the further motion segment, or a combined motion composed of a (further) pivoting motion about their pivoting axis 10 and a (further) rotary motion about their rotation axis 12.

(28) The angle of the rotary motion is likewise predetermined. In the present case, the predetermined pivoting angle of the holding arms 4, 6 about their pivoting axes 12 is 8 in each case. Since the holding arms 4, 6 are rotated equally in opposite directions, an opening angle 14, enclosed by the holding arms 4, 6, to be more specific by the pivoting axes 10, between the holding arms 4, 6 of 16 is accordingly obtained. Alternatively, it is also possible to predetermine some other pivoting angle, and/or to change or adjust the predetermined pivoting angle.

(29) In order to be able to predetermine the position of the holding arms 4, 6 relative to the carrier 2, the device 1 comprises an actuator unit 16.

(30) According to this embodiment, the actuator unit 16 comprises a control rod 18, which can be moved along a control axis 20. In the installed position of the device 1 in the closing device 100, the control axis 20 is in the present case oriented parallel to the direction of gravity. In the present case, the control axis 20 is oriented parallel to the rotation axes 12. In the present case, the control axis 20 is oriented perpendicularly to the pivoting axes 10. However, it is not limited to the above.

(31) At its upper end in FIGS. 3 to 5, the control rod 18 comprises an interaction element, in the present case configured as a running roller 22, which is configured to roll along a cam guide (not shown here), which is arranged for conjoint rotation on a stationary base frame of the closing device 100.

(32) The actuator unit 16 furthermore comprises a transmission assembly 24, via which the control rod 18 is coupled to the holding arms 4, 6 for the purpose of controlling the pivoting movements and rotary movements of the holding arms 4, 6.

(33) FIG. 6 shows schematically a perspective side view of the device 1 according to FIGS. 1 to 5, wherein the view of the interior of the carrier 2 is exposed since the carrier 2, to be more specific a carrier housing of the carrier 2, is cut open.

(34) The actuator unit 16 comprises a first actuator part 26 for controlling the pivoting motion of the holding arms 4, 6 about their respective pivoting axis 10, and a second actuator part 28 for controlling the rotary motion of the holding arms 4, 6 about their respective rotation axis 12.

(35) The first actuator part 26 is connected via in each case one first connecting rod 30 to in each case one radial lever arm 35, which is connected, in this case rotatably connected by means of a ball joint 37, at a predetermined distance from the pivoting axis 10 to a transmission rod 34 that is connected for conjoint rotation to in each case one holding arm 4, 6 and can be pivoted about the pivoting axis 10 of the connected holding arm 4, 6. The second actuator part 28 is connected via in each case one second connecting rod 32 to in each case one of the transmission rods 34, in the present case being rotatably connected via a ball joint 38.

(36) At their holding-arm end, the transmission rods 34 are connected for conjoint rotation, in each case via a ball joint 36, to one of the holding arms 4, 6.

(37) At their end opposite the holding-arm end, they are guided in translation in a translation plane oriented parallel to the holding plane 8 according to this embodiment for example, via a sliding block 41 in a guide groove of a sliding block guide 40 arranged on the carrier 2. The translation plane is the product of the direction of the translational guidance of the sliding blocks 41 in the sliding block guide 40 and the centre of rotation of the ball joint 36.

(38) Also arranged on the carrier 2 is a support section 42 for supporting the container 105 on the retaining ring or on the tamper-evident band 106 of an applied container closure 108 when the holding arms 4, 6 have been moved into the open position. The support section 42 can be arranged at a predetermined distance below the holding plane 8 defined by the holding arms 4, 6 situated in the closed position, wherein, for example, the distance is configured to be such that, in the closed position of the holding arms 4, 6, the applied container closure 108 is spaced apart from the support section 42, in the present case optionally at a distance of 0.1 to 2 mm, e.g. 0.3 to 1 mm. Here, the distance is 0.6 mm.

(39) The control rod 18 is sealed off relative to the carrier 2 by means of a diaphragm seal 44.

(40) The device 1 shown in FIGS. 3 to 5 is configured to be of hermetically sealed construction with the sealing diaphragm seal at the top and further diaphragm seals on the holding arms 4. Alternatively, however, the device 1 can also be configured to be of open construction.

(41) FIG. 7 shows schematically a side view of the holding arm 4, more specifically a holding arm assembly of the holding arm 4 from FIGS. 1 to 6.

(42) As already mentioned, the holding arm 4 is attached to one side of the ball joint 36, more specifically of a ball element 39 of the ball joint 36, and, on the opposite side of the ball joint 36, more specifically of the ball element 39 of the ball joint 36, the transmission rod 34 is attached to the ball element 39. The ball joint 36 provides the pivoting axis 10 and the rotation axis 12 or forms these, the said axes intersecting each other at the centre of rotation 45 of the ball joint 36.

(43) It can furthermore be seen that the lever arm 35 is arranged at a predetermined radial distance 46 relative to the pivoting axis 10.

(44) Moreover, the guidance of the transmission rod 34 via its sliding block 41 in the sliding block guide 40 is illustrated. The orientation of the guidance, i.e. the direction of guidance, in the sliding block guide 40 extends perpendicularly to the plane of FIG. 7. It extends perpendicularly to the rotation axis 12. It extends perpendicularly to the direction of gravity.

(45) The centre of rotation 45 and the direction of guidance define a rotation plane 48, to which the rotation axis 12 of the holding are 4 is perpendicular.

(46) In FIG. 6, the holding arms 4, 6 of the device 1 are in the open position shown in FIG. 5.

(47) The first actuator part 26 and the second actuator part 28 are coupled to the control rod 18 in such a way that, when the control rod 18 is moved downwards out of the position shown in FIG. 6, i.e. towards the holding arms 4, 6 and the transmission rods 34, it is initially only the second actuator part 28 which undergoes a movement in the direction of the control axis 20 towards the transmission rods 34. As a result, the holding arms 4, 6 rotate inwards, i.e. towards one another, about their respective rotation axis 12. This corresponds to the further motion segment described above. After the control rod 18 has travelled a stroke assigned to the further motion segment in the direction of the transmission rods 34, the holding arms 4, 6 are in the intermediate position shown in FIG. 4.

(48) The first actuator part 26 and the second actuator part 28 are furthermore coupled to the control rod 18 in such a way that, after the stroke of the control rod 18 assigned to the further motion segment has been reached or exceeded, that is to say from the intermediate position, only the first actuator part 26 undergoes movement in the direction of the control axis 20 towards the transmission rods 34. As a result, the holding arms 4, 6 pivot inwards and upwards into the closed position about their respective pivoting axis 10. This corresponds to the first motion segment described above.

(49) In order to enable their movements as described above, the actuator parts 26, 28 are each movable within a predetermined travel relative to the control rod 18.

(50) The second actuator part 28 is preloaded against the control rod 18 by a spring (not shown here) and can be moved towards the transmission rods 34 up to a stop (not shown here) arranged on the carrier 2. After contact with the stop, the spring undergoes compression between the control rod 18 and the second actuator part 28.

(51) The first actuator part 26 is preloaded relative to the carrier 2 by a spring (not shown here). In the further motion segment, the control rod 18 moves freely relative to the first actuator part 26, and the latter therefore remains unchanged in its position. In the intermediate position, no contact occurs between a stop (not shown here), arranged on the control rod 18, and the first actuator part 26. In the first motion segment, the first actuator part 26 is then pushed towards the transmission rods 34 via the stop of the control rod 18, and the spring is correspondingly compressed between the first actuator part 26 and the carrier 2. Owing to the movement of the first actuator part 26 towards the transmission rods 34, the holding arms 4, 6 undergo their pivoting motion via their respective pivoting axis 10.

(52) FIG. 8 shows schematically a device 1 for holding a container 105 in a container handling device, e.g. for holding a bottle without a support ring in order to apply a screw closure or a press-on closure, according to another embodiment, which can be used, for example, instead of the device 1 from FIGS. 3 to 6 in the closing device 100 according to FIGS. 1 and 2.

(53) The device from FIG. 8 corresponds substantially to that from FIGS. 3 to 6, but differs only in the construction of the actuator unit 16 and of the coupling to the holding arms 4, 6, i.e. the transmission assembly.

(54) Instead of the connection of the two actuator parts 26, 28 via connecting rods, as described with respect to FIGS. 6 and 7, the actuator unit 16 of the device 1 from FIG. 8 comprises actuator parts 26, 28 which are of plate-shaped design.

(55) The actuator parts 26, 28 are firmly connected to the control rod 18. They comprise guide cams described in greater detail below, via which the pivoting motion and the rotary motion of the holding arms 4, 6 are predetermined.

(56) In FIG. 8, the carrier 2 and the sliding block guide 40, which are of substantially identical design to those shown in FIGS. 3 to 6, and the plate-shaped second actuator part 28 are omitted in order to open up the view towards the plate-shaped first actuator part 26 to enable its mode of operation to be illustrated.

(57) FIG. 9 shows schematically another perspective side view of the device 1 from FIG. 8, in which the second actuator part 28 is inserted to enable its mode of operation to be illustrated.

(58) As can be seen from FIG. 8, the first actuator part 26 comprises a plate-shaped main body 50, on opposite sides of which guide tracks 52 are formed. Guide blocks 54 arranged on the lever arms 35 rest against the guide tracks 52 and, during a movement of the control rod 18 and thus of the first actuator part 26 in the direction of the control axis 20 relative to the transmission rods 34, they slide over their associated guide track 52.

(59) As can be seen from FIG. 9, the second actuator part 28 comprises a plate-shaped main body 58, in which there are slot-type guide tracks 60. Guide blocks 56 arranged on the transmission rods 34 are guided on the guide tracks 60.

(60) In this embodiment too, the mounting of the transmission rods 34 relative to the carrier 2 and the attachment thereof to the holding arms 4, 6 corresponds to the design according to FIG. 7.

(61) In FIGS. 8 and 9, the holding arms 4, 6 are positioned in the closed position.

(62) Owing to the surfaces of the guide tracks 52 of the first actuator part 26 being oblique with respect to the control axis 20, the holding arms 4, 6 undergo a successive pivoting motion during a movement of the control rod 18 out of the position shown in FIGS. 8 and 9 into the closed position. Consequently, the holding arms 4, 6 undergo a pivoting motion in the first motion segment and a further pivoting motion in the further motion segment.

(63) As can be seen from FIG. 9, the guide tracks 60 of the second actuator part 28 comprise a section 62 oriented obliquely to the control axis 20 and an adjoining section 64 oriented parallel to the control axis 20.

(64) During actuation of the control rod 18, i.e. movement of the actuator unit 16 towards the holding arms 4, 6, the guide blocks 56 initially slide parallel to the control axis 20 or to the section 64 oriented parallel to the rotation axis 12. The angular position of the guide blocks 56 and, as a result, also of the sliding blocks 41 relative to the rotation axes 12 associated with them remains unchanged. Accordingly, the holding arms 4, 6 do not undergo a rotary motion in the first motion segment, which is predetermined by the parallel-oriented section 64.

(65) In the further motion segment, which is predetermined by the obliquely oriented section 62, the guide blocks 56 and thus the sliding blocks 41 undergo a movement towards one another. Accordingly, the holding arms 4, 6 undergo a rotation away from one another about their rotation axes 12 in the further motion segment.

(66) The actuator unit 16 furthermore comprises a spring element (not shown here), which preloads the holding arms 4, 6 into the open position, in the present case by virtue of the fact that the spring element preloads the control rod 18 into the position shown in FIGS. 8 and 9.

(67) FIG. 10 shows schematically a sectional view through a device 1 for holding a container 105 in a container handling device according to a further embodiment, which can likewise be used in the closing device 100 according to FIGS. 1 and 2. The device 1 corresponds substantially to that from FIG. 6, wherein, instead of the second actuator part 28 attached to the transmission rods 34 via the connecting rods, the actuator unit 16 comprises a plate-shaped second actuator part 28 similar to the embodiment according to FIGS. 8 and 9. In addition, the slot-shaped sliding block guide 40 is provided directly in a wall of the carrier 2, to be more specific of a carrier housing.

(68) FIG. 11 shows schematically a side view of a partial region of the device 1 from FIGS. 3 to 6. This side view also corresponds to the side views of the same partial regions of the devices 1 according to FIGS. 8 to 10.

(69) It can be seen that the holding arms 4, 6 according to these optional embodiments each comprise a collar-shaped supporting projection region 70 for supporting the container 105 on a retaining ring 109 of the container 105. Accordingly, the supporting projection regions 70 of the holding arms 4, 6 define the holding plane 8 in the closed position.

(70) The pivoting of the holding arms 4, 6 about their pivoting axes causes the supporting projection regions 70 to pivot outwards and downwards in relation to the container 105. Accordingly, in the open position they are radially outside the position of the supporting projection regions 70 in the closed position in the direction of view of a reference axis oriented perpendicularly to the holding plane 8 and arranged centrally between the supporting projection regions 70 situated in the closed position. In the open position, the supporting projection regions 70 are furthermore at a lower height when viewed in the direction of the reference axis than the supporting projection regions 70 in the closed position.

(71) Where applicable, all the individual features which are illustrated in the exemplary embodiments can be combined with one another and/or interchanged without exceeding the scope of the invention.
