Definitions
- the invention relates to a device for producing a locking ring on a closure cap for a container, in particular for a beverage bottle.
- the invention further relates to an arrangement for producing a closure cap for a container comprising the device and a method for producing a closure cap for a container.
- closure caps for such containers are usually provided with a locking ring.
- This locking ring is connected to a base part of the closure cap that fulfills the closing function via a predetermined breaking point, so that when the container is opened, the predetermined breaking point is inevitably damaged and the first opening of the container can thus be reliably recognized from the outside.
- the safety ring is held on the container when the cap part is pulled off or unscrewed at least until the predetermined breaking point breaks.
- the container has an undercut in the form of a bead, for example, on a connecting piece on which the closure cap sits, usually in the pulling direction, which the locking ring engages behind from below, ie counter to an opening direction.
- the locking ring prevents it from being pulled off the bead of the container, so that the predetermined breaking point tears open.
- a circumferential, sometimes interrupted, inwardly folded fold is formed on the locking ring, with which the locking ring engages behind the bead on the container. It is also known to provide a thickened section on the locking ring instead of a fold.
- the breaking point can be designed in such a way that a connection between the base part and the locking ring remains after it has been removed.
- the opening of the container should be freely accessible when the base part is removed, which is easily possible, for example, by means of a suitable design of the predetermined breaking point or the locking ring.
- the base part is thus captively attached to the container via the locking ring when it is intended to be used. This is advantageous in terms of ecological compatibility, in particular a reduction in, for example, uncontrolled disposal of plastic waste.
- Such a cap is for example in the US 2016/0288961 A1 (MJ Maguire ) described.
- several cuts are made in a closure cap blank, which form a predetermined breaking point in such a way that the base part of the closing cap remains connected to the locking ring via several webs after the breaking of the predetermined breaking point.
- such securing rings are produced by cutting the predetermined breaking point into a sealing cap blank.
- such methods are mostly imprecise, as e.g. the folded fold of the locking ring forms an imprecise cutting surface.
- Other processes such as laser cutting are time-consuming and costly.
- the object of the invention is to create a device belonging to the technical field mentioned at the outset, as well as a method which enables the reliable and cost-effective production of closure caps with a locking ring for containers.
- a device for producing a securing ring on a closure cap for a container comprises a stationary cutting knife with a cutting blade extending along a cutting path, the cutting course of which is a slot geometry to be generated in a jacket of a closure cap blank between a base part of the closure cap and corresponds to the locking ring.
- the device further comprises a transport device for transporting the closure cap blank along the cutting path, the transport device comprising a support mandrel for supporting the casing of the closure cap blank, in particular for direct support on the inside of the casing, such that the casing is rolled off on the cutting blade during a cutting process, wherein the support mandrel has a rotatable bearing with which it is rotatably mounted about an axis of rotation oriented perpendicular to the cutting path.
- the invention is characterized in that in a support section of the support mandrel which is opposite the cutting blade during the cutting process, a groove geometry is formed which corresponds at least to the slot geometry to be generated, the device comprising a synchronization device by means of which a movement of the transport device along the Cutting path can be synchronized with a rotary movement of the support mandrel about the axis of rotation.
- the “cutting path” denotes a path section of a transport path of the closure cap blank defined by the transport device during the cutting process.
- the cutting section is arranged in a transport plane which is perpendicular to the axis of rotation of the support mandrel.
- the transport plane is typically aligned horizontally.
- the “cutting knife” denotes an arrangement of one or more cutting blades, which are typically elongated.
- the cutting blades usually have a blade which carries the cutting edges of the cutting blade.
- the cutting edges can be straight or, in particular, concave when viewed from the blade, be curved.
- the "slot geometry” denotes the course of one or more slot sections which are to be produced on the closure cap blank or which are to be present on the completed closure cap.
- the slot geometry has interruptions, whereby connection points between the base part and the locking ring remain.
- the connection points form, for example, support or retaining webs, which are provided in the sense of predetermined breaking points for a complete or partial separation of the base part from the locking ring for separation, and / or connection sections which are provided for a partial separation to remain, ie the After a partial separation, the base part remains connected to the locking ring in the connecting section.
- the "cutting edge course" of the cutting blade refers to the following two, generally superimposed, courses of the cutting edge: A longitudinal course, which describes the cutting edge course along the cutting path and a height course, which the cutting path in a direction perpendicular to the cutting path and parallel to the axis of rotation of the support mandrel designated.
- the longitudinal course of the cutting blade can be interrupted accordingly, for example. If, for example, a corrugated profile of the slot geometry is to be produced in the jacket of the closure cap, the cutting blade has a corresponding corrugated height profile. Should it be necessary that, in addition to the slot geometry, only weakened areas are to be created in the jacket of the closure cap blank, i.e.
- the "transport device” denotes a device which is designed in such a way that the closure cap blank can be transported past the cutting knife in the cutting path in such a way that a cutting process, ie cutting into the casing of the closure cap blank by the stationary cutting knife, takes place.
- the support mandrel of the transport device engages with the support section in an interior of the closure cap blank in such a way that the jacket of the closure cap blank is guided from the interior of the support section against the cutting blade in an instantaneous cutting area.
- the support area of the support mandrel supports the jacket in particular through direct contact with the inside of the jacket in the current cutting area.
- Direct contact here means direct contact of the support area of the support mandrel with the inner surface of the jacket section at least in the current cutting area, ie in that jacket section in which a cutting process is currently taking place.
- the transport of the closure cap blank by the transport device comprises a translational movement along the transport path (feed) as well as a rotary movement superimposed on this feed about an axis of rotation parallel or coaxial to the axis of rotation of the support mandrel.
- the rotational movement of the closure cap blank is supported or achieved by a rotation of the support mandrel about the axis of rotation defined by the rotatable bearing. In this way, the jacket of the closure cap blank can be rolled off on the cutting blades during transport along the cutting path.
- the groove geometry according to the invention in the support area of the support mandrel corresponds at least to the slot geometry to be generated, ie the groove geometry is designed in such a way that it covers at least the course of the entire cutting blade in the course of a complete cutting process.
- the groove geometry for example for manufacturing reasons, can also include further groove sections which go beyond the slot geometry defined by the cutting knife or its cutting blades. It goes without saying that the same groove sections can cover different sections of the course of the cutting blade in the course of more than one revolution of the support mandrel during the cutting process.
- the groove geometry is preferably formed on a lateral surface in the support section of the support mandrel.
- the support section rests, in particular with the jacket surface, on an inner surface of the jacket of the closure cap blank.
- a largest radial outside diameter of the support section is preferably smaller than a smallest radial inside diameter of the closure cap blank so that it can be easily placed on and removed from the support mandrel in the direction of the axis of rotation, i.e. also along a longitudinal axis of the support mandrel. Due to the smaller diameter, the supporting section in this case rolls with its jacket surface on the inner surface of the jacket of the closure cap blank during the cutting process.
- the support mandrel thus executes more than one revolution around its axis of rotation for a complete revolution of the closure cap blank.
- a largest radial outside diameter of the support section largely corresponds to a smallest radial inside diameter of the closure cap blank, so that the closure cap blank can sit snugly on the support section of the support mandrel.
- one complete revolution of the support mandrel corresponds to one complete revolution of the closure cap blank.
- the jacket surface of the support section can be adapted to a course of the inner surface of the jacket of the closure cap blank.
- the outer surface of the support section apart from a groove geometry that is at most not rotationally symmetrical thereon, is configured essentially rotationally symmetrical with respect to the axis of rotation of the support mandrel.
- the device comprises a synchronization device, by means of which a movement of the transport device along the cutting path can be synchronized with a rotary movement of the support mandrel about the axis of rotation.
- a synchronization device by means of which a movement of the transport device along the cutting path can be synchronized with a rotary movement of the support mandrel about the axis of rotation.
- the sealing cap blank is carried along via the support area of the support mandrel, among other things, and is also rolled onto the cutting blades in a synchronized manner, ie experiences a corresponding advance with correspondingly superimposed, synchronized rotary movement.
- the synchronization device can for example comprise a mechanical or an electronic coupling.
- a synchronized coupling of the feed of the transport device with the rotary movement of the support mandrel can be achieved, e.g. via a gear.
- a correspondingly synchronized control of separate drives can be provided for the advance of the transport device and the rotary movement of the support mandrel.
- a control or regulation is conceivable, which e.g. receives data on the current position and / or rotary position via sensors and controls or regulates the respective drives accordingly.
- the groove geometry formed in the support area has the advantage that the jacket of the blanking cap receives largely complete support during the cutting process in the current cutting area, which only needs to be interrupted in the area of the slot geometry to be generated, i.e. in the circumference of the groove geometry.
- the cutting blade or its cutting edge can penetrate the jacket and, in particular, engage in the groove geometry without contact, i.e. be introduced into the groove in a direction perpendicular to the axis of rotation of the support mandrel. In this way, a reliable and well-defined cut for generating the slot geometry is achieved.
- the transport device in particular the support mandrel, or areas or parts of the closure cap blank that are not intended for cutting despite the completely penetrating cut.
- the slot geometry can be produced in a particularly reliable manner with high cutting accuracy.
- the closure capsule blank can also be processed with the jacket unfolded, in contrast to solutions in the prior art, where the section of the jacket folded over to form the securing ring also had to perform a support function when generating the slot geometry.
- the slot geometry to be generated comprises sections which extend at an angle of less than 90 ° to the axis of rotation of the support mandrel.
- the slot geometry can comprise sections which are inclined with respect to the transport plane or, if desired, are perpendicular to it, that is to say are arranged parallel to the axis of rotation of the support mandrel.
- the cutting edge of the cutting blade can have a height profile which comprises sections which can rise or fall in a direction parallel to the axis of rotation. In this way, complex slot geometries can be generated, which allow a versatile application of the device according to the invention.
- Such bends in the slot geometry have the advantage, in particular at the ends of slot sections, that tearing or tearing of the slot in further areas of the closure cap can be prevented or inhibited.
- such angled angles allow the slot geometry to be guided in such a way that a bulge or widening can be created to improve the support, e.g. in areas of greater stress such as a wide interruption in the slot geometry provided as an articulated connection point.
- the slot geometry is simple and only comprises sections which are arranged at an angle of 90 ° with respect to the axis of rotation, i.e. straight slot sections parallel to the transport plane.
- the cutting blade is preferably arranged relative to the support mandrel in such a way that the cutting blade, in particular a cutting edge of the cutting blade, engages in the groove geometry of the support mandrel during the cutting process. In this way it can be ensured that the jacket of the closure cap blank is completely cut through without damaging the cutting knife, the transport device, in particular the support mandrel, or areas or parts of the closure cap blank that are not intended for cutting.
- the cutting blade can also remain radially outside the groove during the cutting process, the groove ensuring that no damage occurs in the event of slight deviations in the radial direction.
- An axial extension of the groove geometry of the support mandrel in the direction of the axis of rotation at least in sections which are oriented perpendicular to the axis of rotation of the support mandrel is advantageously 0.2-0.8 mm, in particular 0.3-0.5 mm.
- the concrete preferred dimensions of the groove geometry depend, for example, on the width with which the slot geometry is to be formed in the jacket or the cutting width of the cutting blades. A certain tolerance in the relative movement of the support mandrel with respect to the stationary cutting knife must also be taken into account. It has been shown that an expansion of 0.2 to 0.8 mm provides sufficient support for the jacket with sufficient space for the cutting edge to engage for most applications.
- a smaller expansion of the groove geometry of 0.3 to 0.5 mm is preferred, with which better support of the jacket and thus ultimately a better sectional view can be achieved.
- a larger expansion of the groove geometry may typically be necessary, since additional space must be created for the engagement of the cutting edges of the cutting blades due to the rotation of the support mandrel.
- the cutting knife can have a modular design and comprise one or more exchangeable cutting elements which complement each other to form the cutting blade. In this way it can be achieved that sections of the cutting knife, which e.g. experience higher wear, e.g. dull faster, can be replaced separately. Likewise, a complex cutting edge course of the cutting knife can be built up modularly in a simple manner by assembling, for example, several straight but relatively inclined sections of different cutting elements.
- sections with an angle of 90 ° with respect to the axis of rotation of the support mandrel and sections with an angle of less than 90 ° can be provided by different cutting elements.
- a cutting element can preferably also comprise all sections of the cutting knife inclined by an angle of less than 90 °, while the remaining sections are provided by one or more further cutting elements. In this way, the inclined sections, which are usually more heavily worn, can be exchanged together.
- these can be replaced by different Cutting elements are provided or each comprise a plurality of replaceable cutting elements.
- the cutting blade (s) of the cutting knife is or are designed in one piece, for example as integral stamped and bent parts on which the cutting edges are formed.
- the cutting knife can have a plurality of cutting blades which are arranged one above the other in the direction of the axis of rotation of the support mandrel, in particular at least partially overlapping.
- multi-layer slot geometry can be generated in a simple manner in the course of, for example, only one complete revolution of the closure cap blank.
- multi-layer designates a slot geometry which has slot sections arranged at different heights in the direction of the axis of rotation of the support mandrel.
- the slot geometry is defined by at least 1.25 revolutions of the support mandrel and the groove geometry of the support mandrel corresponds to a superposition of the slot geometry during the at least 1.25 revolutions.
- the support area of the support mandrel rolls on the inside of the jacket during the cutting process in such a way that in the course of the 1.25 revolutions of the support mandrel, the closure cap blank preferably executes exactly one full turn.
- the support section can have an outer circumference which is smaller than an inner circumference of the jacket of the closure cap blank, which simplifies the insertion and / or removal of the support mandrel into or out of the interior of the closure cap blank.
- the generation of different sections of the slot geometry in the course of more than one revolution can be advantageous, especially in the case of a complex slot geometry, which includes, for example, intersecting slot sections.
- the blanking cap itself performs more than one complete revolution in order to carry out a complete cutting process. It goes without saying that in the case of several revolutions required for a complete cutting process, the cutting path generally comprises a longer section of the transport path than in the case of a cutting process which only requires one revolution.
- the synchronization device preferably comprises a synchronization mechanism which mechanically synchronizes an axis of the rotatable mounting of the support mandrel with a movement of the transport device along the cutting path.
- a mechanical synchronization mechanism typically comprises a gearbox which couples the axis, i.e. an axle body or a shaft, of the support mandrel with the feed of the transport device.
- the transmission can include components that interact with each other in a form-fitting and / or force-fitting manner, such as gear wheels, friction rollers, ring-shaped internal gears or traction drives such as V-belts / toothed belts or chains, etc.
- the transmission is typically designed in such a way that there is a forced coupling between the rotary movement of the axis and the advance of the transport device.
- the synchronization mechanism preferably comprises a ring with internal toothing that is stationary opposite the transport device and on which a toothed wheel that interacts with the axis of the rotatable mounting of the support mandrel, in particular that is firmly connected to the axis, rolls during the movement of the transport device, at least in the area of the cutting path.
- the transmission can of course also have a coupling device, by means of which the two movements can be decoupled if necessary, e.g. for maintenance.
- the synchronization device is accomplished electrically, for example by a corresponding control of separate drives for the advance of the transport device and the rotary movement of the support mandrel.
- the synchronization device preferably comprises a first electric motor for driving an axis of the rotatable mounting of the support mandrel, a second electric motor for moving the transport device along the cutting path, ie for advancing the transport device, and a control device for synchronizing a movement of the first motor and of the second motor.
- servomotors, stepper motors or linear motors or combinations thereof can be used as electric motors, with which the desired movements can be achieved.
- the synchronization device can, for example, comprise a separately driven toothed belt which, via a pinion seated on the axis of the support mandrel, the Rotational movement of the support mandrel is synchronized with the advance of the transport device.
- each support mandrel can also have a separate drive.
- the synchronization device preferably also comprises one or more sensors with which, for example, a rotational position of the axis of the support mandrel and / or a position of the transport device can be monitored or measured.
- the corresponding measurements can be evaluated by the control, which means that the synchronization can be continuously adjusted. It is also understood that the control can be designed as a control loop.
- the transport device is designed as a turntable, with several support mandrels preferably being arranged along a circumference of the turntable.
- the cutting blade of the cutting knife preferably extends along the circumference of the turntable.
- An axis of rotation of the turntable is preferably arranged parallel to the axes of rotation of the support mandrels, the support mandrels being moved past the cutting knife when the turntable is rotated.
- the turntable can, for example, have two support structures which are largely parallel to each other and are arranged perpendicular to the axis of rotation, on which the support mandrels can be mounted directly or indirectly.
- the axes of the support mandrels can be rotatably mounted on one of the support structures, for example with one of their end areas.
- the turntable can advantageously also be designed in such a way that the axes of the support mandrels are only supported on one side of the turntable.
- a support or guide for the closure capsule blanks can be present, which supports or guides them along the transport path.
- a support surface is preferably arranged parallel to the transport plane, at least in the region of the cutting path.
- the invention also relates to an arrangement for producing a closure cap for a container, comprising a device for producing a securing ring as described here and a device for producing an inwardly folded section of the casing of the closure cap.
- An inward folding here denotes a folding of the jacket section, in particular a section of the securing ring, in a direction which is directed towards the interior of the closure cap.
- the device for producing the inwardly folded section of the device for producing the securing ring is preferably arranged downstream in the processing direction.
- the closure cap with the slot geometry generated in the device according to the invention can thus be fed to the downstream device for generating the folded section, for example, from its transport device or from a further transport system.
- the securing ring already generated by the slot geometry is folded inwards at least in sections, so that the production of the closure cap can be completed with the folding.
- the device for producing the inwardly folded section of the device for producing the securing ring can also be arranged upstream in the processing direction.
- a jacket section which after the production of the slot geometry lies in the area of the locking ring, can be folded inward beforehand.
- the already inwardly folded section does not hinder the cutting process, since in this case too the support mandrel with its support area rests in the current cutting area, in particular directly, on the inner surface of the jacket.
- the inwardly folded part of the securing ring ultimately forms a projection running around the inside of the jacket, which is designed as a ring-like and optionally interrupted fold.
- the fold engages behind a bead formed on the container and thus locks the locking ring in the manner of a barb to prevent it from being pulled off. This ensures that the locking ring remains on the container when the base part of the closure cap is completely or partially separated from the locking ring, i.e. the predetermined breaking point provided by the slot geometry is broken.
- the projection can also be formed by a thickened jacket section. In this case, there is no need to fold the jacket section.
- the slot geometry can, however, be created in the same way as with the variants with a rebate.
- an inwardly folded section of the jacket is produced by producing a slot geometry in accordance with step b).
- the inwardly folded section is produced before the securing ring is produced, there is no need to rework the closure cap that has already been cut. If the inwardly folded section is only produced after the securing ring has been produced, the closure cap blank is provided in the unfolded state. After the securing ring has been produced by producing the slot geometry in the device according to the invention, the closure cap with the slot geometry introduced is fed to the device for producing a folded section. In this, the securing ring produced by means of the slot geometry produced is folded inwards, starting from the jacket of the closure cap.
- An unfolded jacket of the closure cap blank is understood here to mean that the jacket is configured in a single layer in the radial direction, that is to say that there are no sections of the jacket are arranged overlapping in a direction perpendicular to the axis of rotation of the support mandrel.
- the support mandrel rests with the support area, in particular directly, on an inner surface of the jacket, the jacket is supported by the support mandrel during the cutting process.
- the support area thus forms a well-defined cutting base for generating the slot geometry.
- the cutting blade can penetrate completely through the jacket and, for example, intervene in the groove geometry without other parts of the closure cap or the support mandrel being able to be damaged.
- the rotational movement is synchronized with the advance of the jacket along the cutting path in such a way that a section of the groove geometry is arranged opposite the cutting blade at every moment during the cutting process in the current cutting area of the cutting edge.
- the cutting blade in particular its cutting edge, is preferably brought into engagement with the groove geometry in the support section of the support mandrel during the cutting process.
- Figures 1a to 1c show a closure cap 1 for closing a container.
- the Figure 1a shows a side view that Figure 1b an oblique image and the Figure 1c a cross section through a main axis A of the closure cap 1.
- Figure 1b an oblique image
- Figure 1c a cross section through a main axis A of the closure cap 1.
- the closure cap 1 comprises a circular end face 2 and a largely tubular socket-shaped jacket 3, which extends away from the end face 2 concentrically with the main axis A of the closure cap 1.
- the end face 2 closes the tubular socket-shaped jacket 3 at one longitudinal end in the direction of the main axis A and is arranged concentrically with this.
- the closure cap 1 is essentially rotationally symmetrical with respect to the main axis A.
- the jacket 3 can be divided into three length sections 3.1 to 3.3.
- the jacket section 3.1 together with the end face 2 forms a base part 4 of the closure cap 1, which closes the opening of the bottle neck.
- the base part 4 typically has on the inside of the jacket 3 a connecting means such as an internal thread or a snap means (not shown), with which it can be attached to the bottle neck by screwing or snapping it on.
- the jacket section 3.3 forms a securing ring 5 which remains on the bottle neck when the base part 4 is removed from the bottle.
- the jacket section 3.3 Towards an open end of the jacket 3, the jacket section 3.3 has a subsection 3.3a which is provided for folding into an interior 1.1 of the closure cap 1.
- the subsection 3.3a is shown in an unfolded state of the locking ring 5.
- the cross-section according to Figure 1c shows the closure cap 1 of Figures 1a and 1b after the subsection 3.3a has been folded inwards and forms an inwardly protruding fold.
- the inwardly protruding fold is provided for engaging behind an undercut formed on the bottle neck in the form of a bead or a notch. With the fold, the securing ring 5 can be hooked on the undercut of the bottle neck and secured against being pulled off.
- the slot geometry 6 is formed between the base part 4 and the securing ring 5, which in the present case comprises two incoherent, partially circumferential slots 6.1 and 6.2.
- the slots 6.1 and 6.2 are formed spaced apart in the longitudinal direction A on the jacket 3. Since the slot geometry 6 is thus formed in two layers, the further jacket section 5.2 is created, which forms an intermediate ring between the base part 4 and the securing ring 5. It goes without saying that with a single-layer slot geometry 6, i.e. if, for example, only the slot 6.1 is present, the jacket section 5.2 and thus the intermediate ring are omitted.
- the slot geometry 6 is produced by means of a device according to the invention and acts at least partially as a predetermined breaking point for the complete or partial separation of the base part 4 from the securing ring 5 during an initial removal of the base part 4 from the bottle neck.
- Figure 1a shows the unrolled slot geometry 6 superimposed for better clarity of its course.
- Figure 1b shows the slot geometry 6 as it is formed on the closure cap 1.
- the slot 6.1 delimits the base part 4 in the longitudinal direction A and is designed to be largely completely circumferential apart from a wide interruption 6.1a.
- the wide interruption 6.1a forms a connection point between the intermediate ring formed by the jacket section 3.2 and the base part 4, which is not intended to be separated when the base part 4 is removed.
- the further course of the slot 6.1 has several narrow interruptions 6.1b, which provide holding or support webs between the base part 4 and the intermediate ring formed by the jacket section 3.2.
- the holding or supporting webs form predetermined breaking points which are provided for separation when the base part 4 is removed from the bottle neck for the first time, i.e. are broken.
- the slot 6.1 is angled towards the end face 2, i.e. has end sections 6.1c which have an angle of less than 90 ° with respect to the direction A.
- the slot 6.2 runs around the jacket 3 only partially and has a wide interruption 6.2a, which in Fig. 1a is arranged on the opposite side of the closure cap 1, ie opposite the interruption 6.1a with respect to the longitudinal axis A (in Figure 1c indicated behind the jacket section 3.3a).
- the wide interruption 6.2a forms a Connection point between the intermediate ring formed by the jacket section 3.2 and the locking ring 5, which is not intended to be separated when the base part 4 is removed.
- the further course of the slot 6.2 has several narrow interruptions 6.2b, which provide holding or support webs acting as predetermined breaking points between the intermediate ring formed by the jacket section 3.2 and the securing ring 5.
- the slot 6.2 has a bulge 6.2c directed away from the base part 4, which is composed of a section offset parallel to the main course of the slot 6.2 in the direction of A and two connecting sections inclined with respect to A.
- the slot 6.2 including the bulge 6.2c is designed to be contiguous.
- the base part 4 After the base part 4 has been removed for the first time, ie when the holding or support webs 6.1b and 6.2b have been separated or broken, the base part 4 remains via the intermediate ring formed by the jacket section 3.2 over the wide interruption 6.1a of the slot 6.1 and The connection points formed by the wide interruption 6.2a of the slot 6.2 are connected to the locking ring 5.
- the base part 4, intermediate ring and locking ring 5 can thus be pulled apart in a zigzag shape from one another after the first removal, the connection points formed by the wide interruptions 6.1a and 6.2a serving as an articulated connection between the parts.
- FIG. 2a shows a detail of a schematic cross-sectional view of a device 10 according to the invention through a support mandrel 12 of a transport device 11 during a cutting process.
- a closure cap blank 1A from which the closure cap 1 is produced by introducing the slot geometry 6 with slots 6.1 and 6.2 with the device 10, is shown in FIG Fig. 2a from the support mandrel 12 in the area of a cutting section S (see e.g. Fig. 3 ) of the device 10 on one fixed cutting knife 13 transported past along a transport path.
- the support mandrel 12 engages with a support area 12.1 in the interior space 1.1 of the closure cap blank 1A.
- a largest radial diameter d of the support mandrel 12 in the support area 12.1 is smaller than the largest radial diameter D of an axial end-side opening of the closure cap blank 1A.
- the opening at the end is determined by the unfolded subsection 3.3a of the casing section 3.3. This ensures that the support mandrel 12 can easily be introduced into the interior space 1.1 in a loading area of the device 10 (not shown) in which the closure cap blank 1A is grasped by the transport device 11.
- the support mandrel 12 can easily be removed again from the interior 1.1 in a removal area (not shown). Due to the smaller diameter d, the axis of rotation B of the support mandrel 12 and the main axis A of the closure cap blank 1A are offset from one another, i.e. are not arranged coaxially.
- the support area 12.1 has a circular cylindrical section 12.2 with which the support mandrel 12 rests directly on an inner side of the jacket 3, in particular in the jacket section 3.2, of the closure cap blank 1A in a current cutting area arranged at the cutting knife 13.
- the support mandrel 12 is arranged on a turntable 14 of the device 10 so as to be rotatable about an axis of rotation B (see e.g. Fig. 6 and 7th ).
- the turntable 14 provides a feed along the transport path T while a rotation of the support mandrel 12 or the support area 12.1 about the axis of rotation B supports a superimposed rotation of the blanking cap 1A.
- the current transport path T is aligned at least in the area of the cutting path S essentially perpendicular to the axis of rotation B and is shown in FIG Fig. 2a perpendicular to the plane of the drawing.
- the longitudinal axis A of the closure cap blank 1A is arranged parallel to the axis of rotation B of the support mandrel 12.
- a support surface 16 supports the closure cap blank 1A on the end face 2 and prevents the closure cap blank 1A from slipping off in the direction from B.
- the locking ring 5 of the closure cap blank 1A is unfolded during the cutting process, ie the subsection 3.3a of the jacket section 3.3 is not folded into the interior 1.1 of the closure cap blank 1A and extends away from the end face 2 in the direction of A.
- the fixed cutting knife 13 is arranged on a holding structure 15 of the device 10 that is fixed opposite the turntable 14 in such a way that a cutting blade 13.2 of the cutting knife 13 protrudes in the area of the jacket 3 into the transport path of the closure cap blank 1A.
- a contact surface 15.1 of the holding structure 15 serves to support the closure cap blank 1A laterally, ie perpendicular to the direction of rotation B, on an outer side of the jacket section 3.1 (see also FIG Fig. 4 and 5 ).
- a groove geometry 7 is formed in the support area 12.1 on the circular cylindrical section 12.2, which in the present case comprises two groove sections 7.1 and 7.2.
- the groove geometry 7, ie the groove sections 7.1 and 7.2, are designed and arranged in such a way that the sections of a cutting edge of the cutting blade 13.1 or 13.2 (see also Fig. 4 or 5 ) protrude into one of the groove sections 7.1 or 7.2.
- the cutting blade 13.1 or 13.2 penetrates the jacket 3 in the current cutting area, in particular in the jacket area 3.2, and creates a local section of the slots 6.1 or 6.2 of the slot geometry 6 of the closure cap 1.
- Figure 2b shows a partial view of a device 10 ′, which essentially corresponds to the device 10.
- the device 10 ' is provided for cutting a closure cap blank 1A' which has a sub-section 3.3a 'of a jacket section 3.3' of a jacket 3 'which is already folded inward before the cutting process.
- a cylindrical section 12.2 'of the support mandrel 12' directly supports the inside of a jacket 3 'of the closure cap blank 1A'.
- a support area 12.1 'of a support mandrel 12' of the device 10 ' is designed in such a way that there is space for receiving the already folded sub-section 3.3a'.
- the device 10 ' is shown in FIG Figure 2b in a region of the cutting path S in which, in the current cutting region, sections of both cutting blades 13.1 and 13.2 are simultaneously in Groove sections 7.1 'and 7.2' of the support mandrel 12 'protrude.
- the cutting blades 13.1 and 13.2 simultaneously penetrate a jacket section 3.2 'of the jacket 3' of the closure cap blank 1A '.
- Figure 3 shows in an upper area a schematic view of the cutting knife 13 with two cutting blades 13.1 and 13.2 and in a lower area a representation of the corresponding groove geometry 7 of the support mandrel 12 with groove sections 7.1 and 7.2.
- a height profile of the cutting blades 13.1 and 13.2 corresponds to the superimposed representation of the slots 6.1 and 6.2 of the Fig. 1a .
- the main direction of the cutting blades 13.1 and 13.2 is oriented in the direction of the transport path T and their entire length defines the cutting path S.
- the main direction of the cutting blades 13.1 and 13.2 is oriented perpendicular to the axis of rotation B of the support mandrel 12.
- the cutting blades 13.1 and 13.2 are arranged one above the other in the direction of B and partially overlap in a projection along the axis of rotation B.
- the lower cutting blade 13.1 comprises two sections separated by a wide interruption 13.1a. Each of these sections has several narrow interruptions 13.1b. Towards the wide interruption 13.1a, angled sections 13.1c1 are formed at the ends, which are inclined with respect to the direction B, i.e. have an angle ⁇ ⁇ 90 °.
- the length of the cutting blade 13.1 in its main direction along the transport path T is dimensioned such that it corresponds at least to the length of an outer circumference of the jacket 3 of the closure cap blank 1A.
- the slit 6.1 is produced with the cutting blade 13.1, the slit areas produced by the end areas 13.1d and 13.1e adjoining or slightly overlapping after one complete revolution of the closure cap blank 1A.
- the cut 6.1 produced by the cutting blade 13.1 is thus formed continuously at the outer ends facing away from the wide opening 6.1a.
- the wide interruption 13.1a of the cutting blade 13.1 creates the interruption 6.1a of the slot 6.1, while the narrow interruptions 13.1b generate the narrow interruptions 6.1b.
- the cutting blade 13.2 is arranged centrally above the cutting blade 13.1 in the transport direction T. In the area of the wide interruption 13.1a, the cutting blade 13.2 has a bulge 13.2c in the direction of the axis of rotation B.
- the bulge 13.2c is seated composed of three cutting edge sections 13.2c1 and 13.2c2.
- the cutting edge sections 13.2c1 are inclined with respect to the direction B, ie have an angle ⁇ ⁇ 90 °.
- the cutting edge section 13.2c2 which runs perpendicular to the direction B, is arranged between the inclined cutting edge sections 13.2c1.
- the bulge 13.2c produces the bulge 6.2a of the slot 6.2. Outside the bulge 13.2c, the cutting blade 13.2 has several narrow interruptions 13.2b, which produce the interruptions 6.2b in the slot 6.2.
- the cutting blade 13.2 is overall shorter than the cutting blade 13.1 and thus only covers part of the outer circumference of the closure cap blank 1A. This results in the wide interruption 6.2a of the slot 6.2 due to the cutting-free sections 13.2a along S.
- the lower section of the Fig. 3 shows the corresponding groove sections 7.1 and 7.2 of the support mandrel 12, which are formed in the support area 12.1, in particular in the circular cylindrical jacket section 12.2.
- the view of the Fig. 3 shows a rolling of the circular cylindrical jacket section 12.2 on an imaginary plane.
- a length of a circumference U of the circular cylindrical casing section 12.2 is shorter than the cutting path S.
- the cutting path S in the present case corresponds essentially to a length of an outer circumference of the casing 3 of the closure cap blank 1A.
- the support mandrel 12 thus executes more than one revolution about its axis of rotation B.
- the cutting blade 13.1 is thus only partially covered by the groove section 7.1.
- the end areas 13.1d and 13.1e of the cutting blade 13.1, which are aligned perpendicular to the direction of rotation B, are therefore covered by end areas 7.1e and 7.1d of the groove section 7.1, which are also aligned perpendicular to the direction of rotation B, in the course of a previous or a subsequent rotation of the support mandrel 12 (in Fig. 3 indicated by dashed lines).
- Figures 4 and 5 show a detail of an exterior view ( Fig. 4 ) as well as a combined exterior view with partial sectional view ( Fig. 5 ) of the device 10 according to the invention in the area of the cutting path S without a blanking cap 1A.
- the support mandrel 12 of the transport device 10 is moved in a translatory manner along a transport direction T (Feed rate V).
- the support mandrel 12 rotates with the support area 12.1 about its axis of rotation B in such a way that the groove geometry 7 with groove sections 7.1 and 7.2 formed in the circular cylindrical jacket surface 12.2 of the support area 12.1 is rolled congruently onto the cutting blades 13.1 and 13.2 of the cutting knife 13.
- the groove geometry 7 has a course which covers the course of the cutting edge on the circumference of the support area 12.1 in the course of more than one revolution of the support mandrel 12 (see also, for example Fig. 3 ).
- the cutting blades 13.1 and 13.2 engage in the current cutting area in the groove sections 7.1 and 7.2 (see also, for example Fig. 5 ).
- the contact surface 15.1 has teeth which interact with the longitudinal corrugation of the outside of the jacket section 3.1 in such a way that the closure cap blank 1A is rotated along the transport direction when the support mandrel 12 is advanced.
- the toothing of the contact surface 15.1 thus acts as an internal toothing into which the longitudinal corrugation engages like a toothed wheel.
- a distance between the support mandrel 12 and the contact surface 15.1 and the cutting blades 13.1 and 13.2 is dimensioned such that the blanking cap 1A can be arranged or clamped between the support area 12.1 and the contact surface 15.1 and the cutting blades 13.1 and 13.2.
- the transport path T is curved, preferably circular, at least in the region of the cutting path S.
- the cutting knife 13, ie in particular the cutting blades 13.1 and 13.2 are correspondingly curved and follow the course of the transport path T.
- the cutting knife 13 can have a modular structure and in particular have an easily exchangeable cutting edge module 13.3 in which the inclined sections 13.1c1 and 13.2c1 are arranged. Since experience has shown that these sections are exposed to greater wear, it is advantageous to design at least this area so that it can be replaced separately.
- Figure 6 shows schematically a plan view along the axis of rotation B of the support mandrel 12 onto the transport path T along a circularly curved path.
- the cutting knife 13 or its cutting blades 13.1 and 13.2 are curved according to the transport path T, so that the support mandrel 12 on its path of movement during the advance V of the transport device 10 at a constant distance from the cutting knife 13 along this is moved.
- the support mandrel 12 rotates about its axis of rotation B in a rotational movement R.
- the transport path T in the area of the cutting knife 13 defines the cutting path S.
- Figure 7 shows a schematic view of the device 10 according to the invention with the transport device 11, which comprises the turntable 14 and the support mandrel 12.
- the support mandrel 12 is mounted on the turntable 14 (shown in dashed lines).
- the turntable 14 is only indicated schematically here and can comprise one or more support structures on which the support mandrel 12 is mounted on one or more counter bearings 14.1 with respect to the turntable 14 so as to be rotatable about the axis of rotation B.
- the support mandrel 12 can, however, also have, for example, a housing in which the rotatable mounting is formed and which is firmly anchored on the turntable 14.
- the turntable 14 is mounted on a stationary holding structure (not shown) of the device 10 so as to be rotatable about an axis of rotation C.
- a rotary movement r of the turntable 14 about the axis of rotation C defines the advance V of the support mandrel 12 of the transport device 11 along the transport path T.
- the transport path T is thus circular. It goes without saying that a plurality of support mandrels 12 can be arranged rotatably on the turntable 14 along the circumference, which are moved simultaneously along the transport path T and pass the cutting path S one after the other.
- a gear 12.4 is fixedly arranged coaxially with the axis of rotation B on an axle body 12.3 of the support mandrel 12, which is arranged coaxially with the axis of rotation B.
- the gear wheel 12.4 rolls on an internal toothing 17.1 of a ring 17 which is stationary with respect to the turntable 14.
- the rotary movement R of the support mandrel 12 can be synchronized with the feed rate V given by the rotary movement of the turntable 14.
- the rotational movements R and r have opposite directions of rotation.
- the synchronization can be selected such that the lateral surface 12.2 of the support mandrel 12, including the groove geometry 7, is rolled exactly on the cutting knife 13, so that the cutting edges of the cutting blades 13.1 and 13.2 are each arranged in the groove sections 7.1 and 7.2 in the current cutting area could be.
- the gear 12.4 together with the ring 17 thus forms part of a simple to design synchronization device of the device 10.
- the gears 12.4 of all support mandrels 12 can roll on the same ring 17, so that it couples the rotary movements R of the support mandrels 12 about the respective axes of rotation B.
- Figure 8 shows an alternative embodiment of the device 10, in which a synchronization of the rotary movements R and r of the support mandrel 12 and the turntable 14 (in Fig. 8 not shown) via a separate drive 18 is achieved.
- the drive 18 drives a toothed belt 19 which runs via pinions 12.5 from several support mandrels 12 which are rotatably mounted about local axes of rotation B on the turntable 14.
- the toothed belt 19 runs on the outside in a direction opposite to the direction of rotation of the rotary movement r of the turntable 14 over the pinion 12.5, so that the support mandrels 12 rotate around the respective axis of rotation B with the opposite direction of rotation to r.
- the toothed belt 19 thus couples the rotary movement of all support mandrels 12 about their respective axis of rotation B and rotates with the turntable 14.
- By controlling the drive 18, an independent synchronization of the rotary movements R of the support mandrels 12 with the advance V of the transport device 11 can be achieved.
- a device according to the invention enables particularly reliable and cost-effective production of closure caps with a locking ring for containers, with complex slot geometries being able to be created to create a predetermined breaking point between the base part and the locking ring.
