Description

Device for closing containers by means of rolled closures
Technical Field
The present utility model relates to a device for closing containers by means of rolled closures, for example for closing beverage containers by means of rolled closures in beverage filling facilities.
Background
It is known to close beverage bottles by means of roll-on closures. In this case, a closure preform, usually made of aluminum, having the shape of a hollow cylinder closed on one side, is fitted over the container mouth provided with external threads. After the preform is fitted onto the container finish, the hollow cylindrical side/side surface of the closure is only obtained in its final shape during the closing process by means of a thread and optionally by means of a crimped securing ring.
For this purpose, a device, also called a closure head, is lowered in a cam-controlled manner onto the bottle with the cap already fitted, wherein it applies a preset head pressure via a tappet to the end face of the cap, which corresponds to its upper face, in order to be able to ensure that: the seal placed between the container finish and the closure is sealingly retained on the container finish by the closure after closure.
In order to introduce the thread and the bead of the fastening ring or of the safety belt into the side of the closure cap, the device has a plurality of retrofit arms which are pivotably arranged on a carrier which can be rotated about its longitudinal axis relative to the tappet, each of the retrofit arms having a retrofit roller for introducing the retrofit into the side of the rolled closure cap. In this case, the at least one retrofit roller is configured as a thread roller for introducing threads into the side face, and the at least one retrofit roller is configured as a crimp roller for introducing crimps into the side face of the roll-type closure. In order to introduce the above-mentioned retrofit, the retrofit rollers are pivoted in the direction of the side faces of the cover by lowering the actuators interacting with the retrofit arms, so that they each retrofit the side faces of the cover with a respective preset force. By rotating the carrier, the retrofit roller rolls in the circumferential direction onto the side, so that the thread is punched by the helical movement of the thread roller and the fastening ring or the safety belt is punched by the circumferential movement of the crimping roller.
As mentioned above, the rolled closure can be configured with or without a bead and thus with or without a safety band or a securing ring. Accordingly, in a rolled closure provided with a safety belt or a securing ring, a crimping roller needs to be engaged on a side surface of the rolled closure for punching or "crimping" the safety belt or the securing ring. In the case of a rolled closure without the latter, the crimping rollers accordingly do not have to be crimped either. It is known from this that the closure heads for roll-type closures are designed with or without crimping rollers, which are suitable only for processing certain types, i.e. with or without crimping, respectively. In the transition from processing a rolled closure of the type having a bead to processing a rolled closure of the type having no bead, the closure head on the capping machine is replaced accordingly, and vice versa. This results in relatively long retrofit times. Furthermore, the two types of capping heads can be manufactured separately and store the corresponding unwanted types of closure heads.
To take the above drawbacks into account, it is known to activate or deactivate the crimping rollers in the capping machine. Such designs are known, for example, from EP 2 217 392 B1, EP 2 197 605 B1 or DE 10 2005 023 067A1. However, such capping machines do not have a capping head as described above, but rather include a separate device to enable the bead to be punched into the cap.
Disclosure of Invention
Starting from the known prior art, it is an object of the present utility model to provide an improved device for closing a container by means of a rolled closure, preferably for closing a beverage container by means of a rolled closure in a beverage filling plant.
The object is achieved by a device for closing a container by means of a rolled closure, preferably by means of a rolled closure in a beverage filling plant, having the features of the utility model. Advantageous refinements result from the description and the drawing.
Accordingly, a device for closing a container by means of a rolled closure, preferably for closing a beverage container by means of a rolled closure in a beverage filling facility is proposed, comprising: a tappet for applying a head pressure to a rolled closure to be rolled; a carrier rotatable about its longitudinal axis relative to the tappet; a retrofit arm pivotably arranged on the carrier, the retrofit arm having a retrofit roller rotatably supported on the retrofit arm relative to the retrofit arm for introducing the retrofit into the side of the roll-on closure; and an actuator arranged on the carrier in a displaceable manner relative to the retrofit arm in the direction of the longitudinal axis for pivoting the enclosure arm into the retrofit position. The actuator is pivotable about the longitudinal axis between an operating position, in which it causes a pivoting of the retrofit arm by displacement in the direction of the longitudinal axis, and an idle position, in which it is disengaged from the retrofit arm.
Since the actuator is pivotable about the longitudinal axis between an operating position, in which the actuator causes the pivoting of the retrofit arm by displacement in the direction of the longitudinal axis, and an idle position, in which the actuator is disengaged from the retrofit arm, it is therefore not necessary to predetermine: whether the capping machine must be configured for closing the container with a roll-type closure, wherein the bead is introduced to form a retaining ring or a safety band in the roll-type closure, or no bead is introduced.
The capping machine is then not limited to: the type of rolled closure that is used to handle a certain type of closure, i.e., with or without a bead, is predetermined as would be the case in conventional capping machines with conventional closure heads due to the wide variation in interface between the capping machine and the closure head according to the respective system. For this reason, it is also difficult in conventional capping machines to integrate the retrofit closure head with the switchable hemming roller.
In contrast, thanks to the provision of the pivotable actuator described above, it is possible in the existing capping machines or systems to provide in a simple manner also by means of the provision of the device described above, which represents or is a closure head, to activate the bead for introducing the securing ring or securing ring when a rolled closure of the type having a securing band or securing ring should be handled, and to deactivate the switching between the beads when a rolled closure of the type not having a securing band or securing ring should not be handled.
According to a further preferred embodiment, the actuator has an interaction section for actuating the retrofit arm when the actuator is displaced in the direction of the longitudinal axis, wherein the interaction section is positioned at the level of the retrofit arm, viewed in the circumferential direction with respect to the longitudinal axis, in the operating position, wherein the interaction section preferably has a raised radial extension away from the retrofit arm in the direction of the longitudinal axis, and/or the actuator has a recess for receiving the retrofit arm when the actuator is displaced in the direction of the longitudinal axis in the idle position. The switching between the operating position and the idle position can thus be effected in a simple manner, and furthermore the actuator can have a simple structure and be produced easily.
According to a further preferred embodiment, the carrier comprises a locking element for locking the actuator in the operating position or in the idle position. It is thus possible to ensure that: the actuator remains in the predetermined position and is not undesirably removed from the set position during operation. Preferably, the locking element is formed displaceably in the direction of the longitudinal axis. In order to be able to prevent undesired movements of the actuator from the respective position, the locking element can be held and/or pretensioned into the locking position and can be moved out of the locking position in order to release the lock. Preferably, the locking element is held in the locking position by gravity. In addition or alternatively, a fastening element, for example an elastically deformable fastening element, for example in the form of an O-ring, made of an elastomer and/or thermoplastic, can be provided, which prevents the locking element from being undesirably removed from the locking position. Preferably, the fastening element is designed such that, when a predetermined release force is applied, the locking element can be moved beyond the fastening element in order to be able to release the locking again.
It has proven to be advantageous if the locking element comprises a projection or a protuberance which can be engaged and disengaged with a first receptacle provided on the actuator, preferably in the form of a pocket, for accommodating the protuberance in the operating position and/or with a second receptacle provided on the actuator, preferably in the form of a pocket, for accommodating the protuberance in the idle position.
According to a further preferred embodiment, the locking element is integrated into a quick change coupling device for coupling the device to a closure for closing a container by means of a roll-on closure. A particularly simple construction of the device can thus be achieved. In particular, the two functions, namely the coupling of the device to the closure, or to a "capping machine" synonymous with the latter, and the pivotability of the actuator between the operating and idle positions in a lockable manner, are provided by the provision of quick-change coupling means.
It has proven to be particularly advantageous if the quick change coupling has a locking member displaceable in the direction of the longitudinal axis, preferably comprising a locking pin for locking the quick change coupling in the coupled position, wherein the locking element is preferably arranged on the locking member.
According to a further preferred embodiment, the locking member comprises an annular body, wherein the locking element is formed in the form of a projection on an end side of the annular body pointing in the direction of the actuator.
Preferably, the actuator comprises a receptacle for receiving the locking element in the operating position and/or in the idle position, preferably two receptacles for receiving the locking element, wherein preferably a first receptacle, preferably a receptacle in the form of a pocket, is configured for receiving the locking element in the operating position and/or a second receptacle, preferably a receptacle in the form of a pocket, is configured for receiving the locking element in the idle position.
According to a preferred embodiment, the retrofit roller is configured as a threaded roller for introducing threads into the side of the roll-type closure. Alternatively, the retrofit roller can also be configured as a crimping roller for introducing the crimp into the side of the rolled closure.
Preferably, the device has a plurality of retrofit rollers, wherein preferably at least one retrofit roller is configured as a threaded roller and preferably at least one retrofit roller is configured as a crimping roller. In this case, it has proved to be advantageous if the device has exactly two thread rollers and exactly two crimping rollers.

Detailed Description
Preferred embodiments are described below with reference to the accompanying drawings. Here, the same, similar or identically functioning elements are provided with the same reference numerals in different drawings, and repeated descriptions of these elements are partially omitted so that redundancy can be avoided.
Fig. 1 schematically shows a side view of a device 1 for closing a container by means of a roll-type closure, which is currently alternatively designed for closing a beverage container by means of a roll-type closure in a beverage filling installation. The device 1 comprises a tappet 2 for applying a head pressure to a rolled closure to be rolled, a carrier 4 which can be rotated relative to the tappet 2 about its longitudinal axis 3, and a plurality of retrofit arms which are pivotably arranged on the carrier 4 and each have a retrofit roller which is rotatably mounted on the retrofit arm relative to the retrofit arm for introducing the retrofit into the side of the rolled closure.
In the preferred embodiment, the two retrofit rollers opposite with respect to the longitudinal axis 3 are designed as thread rollers 6' for introducing threads into the sides of the roll-formed closure, and the two further retrofit rollers opposite with respect to the longitudinal axis 3 are designed as crimping rollers 6 for introducing crimps into the sides of the roll-formed closure, in order to be able to form a fastening ring or a securing band on the roll-formed closure.
The device 1 further comprises an actuator 7, which is arranged on the carrier 4 displaceably in the direction of the longitudinal axis 3 relative to the retrofit arm, for pivoting the retrofit arm into the retrofit position.
As explained in detail with respect to fig. 2 to 9, the actuator 7 is pivotably formed about the longitudinal axis 3 between an operating position in which the actuator 7 causes a pivoting of the retrofit arm 5 comprising the hemming roller by a displacement in the direction of the longitudinal axis 3 and an idle position in which the actuator 7 is disengaged from the retrofit arm 5 comprising the hemming roller.
Fig. 2 schematically shows a detailed side view of a partial region of the carrier 4 and the actuator 7 in fig. 1. The actuator 7 comprises an interaction section 8 for operating the retrofit arm when the actuator 7 is displaced in the direction of the longitudinal axis 3.
The interaction section 8 is positioned at the level of the retrofit arm in the operating position, viewed in the circumferential direction with respect to the longitudinal axis 3, wherein the interaction section 8 preferably has a raised radial extension away from the retrofit arm in the direction of the longitudinal axis 3. Currently, the radial extension starts at a first radius R and gradually increases from said radius to a second radius R, which is greater than the first radius R by a preset magnitude Δr. The actuator 7 also has two recesses 9 opposite one another about the longitudinal axis 3 for accommodating the retrofit arms when the actuator 7 is displaced in the direction of the longitudinal axis 3 when the actuator is in the idle position.
Fig. 3 schematically shows a top view along the longitudinal axis 3 shown in fig. 2, wherein the orientation of the recess 9 visible in fig. 2 is indicated by means of reference numeral 10 when the actuator 7 is positioned in the operating position.
As can be seen from fig. 1 and 2, the carrier 4 comprises a locking element 11 for locking the actuator 7 in the operating or idle position. The locking element 11 is currently formed displaceably in the direction of the longitudinal axis 3. According to this embodiment, the locking element 11 is held in the locking position shown in fig. 1 and 2 by gravity. Alternatively or additionally, the locking element 11 can also be preloaded into the locking position. In order to release the locking, the locking element 11 can be moved out of the locking position against gravity in the direction of the longitudinal axis 3.
In this alternative embodiment, the locking element 11 is integrated into a quick change coupling device 13 for coupling the device 1 to a closure for closing a container by means of a rolled closure. The quick change coupling 13 comprises a locking member 14 displaceable in the direction of the longitudinal axis 3, comprising a locking pin (not shown) for locking the quick change coupling 13 in the coupled position, wherein the locking element 11 is arranged on the locking member 14.
The locking member 14 currently comprises or is configured as an annular body. The locking element 11 is formed in the form of a projection on the end face of the annular body which is directed in the direction of the actuator 7.
The actuator 7 comprises a receptacle 15 pointing in the direction of the locking member 14 for receiving the locking element 11 in the operating position and a further receptacle 15 'for receiving the locking element 11 in the idle position, wherein the receptacle 15 for receiving the locking element 11 in the operating position is spaced apart from the further receptacle 15' for receiving the locking element 11 in the idle position by a predetermined angle in the circumferential direction with respect to the longitudinal axis 3.
Fig. 4 schematically shows a further detail side view of the partial region of the carrier 4 and the actuator 7 in fig. 2, wherein the locking member 14 and thus the locking element 11 are moved out of the locking position shown in fig. 1 and 2, in which the locking member 14 is lifted parallel to the longitudinal axis 3 against gravity by a predetermined amount in the lifting direction 16, so that the locking element 11 is disengaged from the receptacle 15. The actuator 7 can thus be pivoted about the longitudinal axis 3 from the operating position shown in fig. 1 to 3 in the direction 17 shown in fig. 5, as is indicated in fig. 4 and 5.
Fig. 6 shows schematically a further detailed side view of the partial region of the carrier 4 and the actuator 7 according to fig. 2 and 4, wherein the actuator 7 has been pivoted into the idle position. Furthermore, the locking member 14 is lowered onto the actuator 7 in the direction of gravity g, so that the locking element 11 engages with the receptacle 15'. Thus, the actuator 7 is locked in the idle position. As described above, in the idle position, the recess 9 is provided such that it accommodates the retrofit arm 5 comprising the hemming roller on which the hemming roller is provided, when the actuator 7 is lowered onto the retrofit arm, without causing a pivoting of the retrofit arm due to interaction with the actuator 7. Accordingly, when the actuator 7 is lowered onto the retrofit arm, the retrofit arm 5' comprising the threaded roller is pivoted only due to interaction with the interaction section 8 of the actuator 7 for introducing the thread into the roll-type closure, but does not crimp the safety band or the securing ring.
As can also be seen from fig. 1, a securing element in the form of an O-ring 12 is provided, which prevents the locking element 11 from being undesirably removed from the locking position.
Fig. 7 schematically shows a pivoting movement of the actuator 7 about the longitudinal axis 3 from an operating position, indicated by means of reference numeral 10, with a preset pivot angle 19 into an idle position, in which the position or orientation of the recess 9 is indicated by reference numeral 18.
Fig. 8 shows schematically a bottom view of an actuator 7 according to a further embodiment, wherein the actuator 7 is in an idle position such that the interaction section, although engaging with a retrofit arm 5' comprising a thread roller indicated by means of a dashed line, enables a thread to be formed into the rolled closure, but without the aid of a retrofit arm 5 comprising a crimping roller via which a crimp for producing a safety belt or a securing ring on the rolled closure can be introduced. Since the actuator 7 is in the idle position, the recess 9 is arranged at the level of the actuator 7, viewed in the circumferential direction with respect to the longitudinal axis 3. The position of the recess 9 in the idle position is again indicated by means of reference numeral 10.
Fig. 9 schematically shows a further bottom view of the actuator 7 from fig. 8, with the actuator 7 in the operating position. The position or orientation of the recess 9 in the operating position is currently indicated with reference numeral 18. In the operating position, the actuator 7 pivots about the longitudinal axis 3 by a pivot angle 19. Thus, when the actuator 7 is lowered onto the retrofit arm, the retrofit arm is engaged with the interaction section 8 of the actuator 7. The recess 9 is arranged in the operating position in such a way that it has no influence on the positioning of the retrofit arm when the actuator 7 is lowered onto the retrofit arm in the direction of the longitudinal axis.
All the individual features shown in the embodiments can be combined with each other and/or replaced, as applicable, without departing from the scope of the utility model.
