Definitions

  • the invention relates to a method for producing a cutting geometry running in the circumferential direction, in particular for producing a securing ring, in a casing of a closure cap for a container.
  • the invention also relates to a device for carrying out such a method.
  • 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 usually has an undercut in the pulling direction on a connecting piece on which the closure cap is seated, e.g. B. in the form of a bead, which is engaged from behind by the locking ring from below, ie against an opening direction.
  • a connecting piece on which the closure cap is seated e.g. B. in the form of a bead
  • 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 typically formed on the securing ring, with which the locking ring engages behind the bead on the container. It is also known to provide a thickened section on the inside of 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 removal (“tethered cap”). This is with a view to ecological compatibility, in particular a reduction in z. B. uncontrolled disposed plastic waste, advantageous.
  • such securing rings are produced by cutting a cut geometry into a closure cap.
  • the cutting geometry corresponds to one or more predetermined breaking points.
  • the sealing caps can be moved past a cutting knife and rolled on this to break the predetermined breaking point in the form of a z. B. to produce partially interrupted slot in the jacket of the closure cap.
  • closure caps that are not completely rotationally symmetrical, however, it is often desirable or necessary to produce the cut according to a predeterminable orientation of the closure cap.
  • This can e.g. B. be the case when a print image to be applied is to be aligned with non-rotationally symmetrical elements of the closure cap.
  • Such elements can include, for example, a non-rotationally symmetrical securing ring (guarantee band) produced in the course of the cutting process or a securing strap of the closure cap.
  • closure caps with a lid that can be opened via a hinge and which is secured with bars on the base body until it is opened for the first time, it is also essential that the hinge is not destroyed during the cutting process ("flip-top" arrangement).

B. a cutting knife for generating a cutting geometry in the jacket of the closure cap, a printing station for printing the closure cap and / or a folding device which folds a jacket portion of the closure cap to produce a locking ring.
  • the processing section comprises at least one cutting section, along which the cutting blade or several cutting blades of the cutting knife extend or extend.
  • the cutting path forms at least part of the processing path, but can in particular also correspond to the entire processing path.
  • Each cutting blade protrudes like this in the transport path of the closure cap that a cutting edge or several cutting edges of the cutting blade produce one or more cuts in the casing of the closure cap when it is transported by the transport device along the cutting path.
  • the closure cap is moved from the transport device to the cutting blade in the cutting section.
  • the transport path can comprise a feed section which lies in the process direction in front of the processing section and preferably directly adjoins it.

  • cutouts are required for the hinge in the cutting geometry of the slot, so that an oriented feeding of the closure cap is essential.
  • the feeding of the closure cap to the processing line is achieved with a predeterminable orientation of a rotational position with respect to a central axis of the closure cap by bringing a driver of the transport device rotating about an axis of rotation into engagement with a stop of the closure cap during feeding.
  • a movement of the rotating driver is controlled in such a way that the driver has a rotational position corresponding to the predeterminable orientation of the sealing cap when the closure cap enters the processing path.
  • the rotating driver is preferably brought into engagement with the stop of the closure cap by means of a rotary movement about its axis of rotation.

  • the axis of rotation of the rotating driver is advantageously arranged perpendicular to the transport plane.
  • the movement of the rotating driver is preferably controlled in such a way that the rotating driver and the stop of the closing cap within a complete relative rotation between the closing cap and driver during feeding necessarily come to the intervention.
  • the rotation of the driver "overtakes” any spontaneous or previously introduced rotation with any initial orientation of the rotational position of the closure cap, so that the driver and the stop can be brought into engagement in any case.
  • the closure cap can already be provided with a certain orientation or with a certain orientation range, so that, starting from an initial rotational position of the driver, no complete relative rotation is required for reliable engagement of the stop and the driver.
  • the engagement is preferably maintained at least until it enters the processing section.
  • the rotational movement of the rotating driver about its axis of rotation is controlled in such a way that a rotational speed during the feeding corresponds to a rotational speed in the area of the processing path.
  • the rotating driver rotates at a constant speed as it traverses the transport path.
  • the speed of rotation is preferably selected in such a way that the driver and the stop can engage during feeding, i.e. the speed of rotation of the driver is higher than a rotation of the closure cap about its central axis.
  • the speed of rotation of the closure cap can be increased in such a way that it rotates faster than the driver.
  • the engagement can thus be released by the lower rotational speed of the driver.

  • the engagement or the release of the engagement can also be achieved by controlling the rotational speed of the rotating driver.
  • the rotational movement of the rotating driver is therefore controlled about its axis of rotation in such a way that a first rotational speed during feeding is higher than a second rotational speed in the area of the processing path, in particular during rolling in the cutting process.

  • the inhibition can be selective along the whole Transport route, in particular in the feed line, take place and z. B. can be achieved by the action of a frictional resistance on the cap.

  • the contact surface 11 has a ramp 12 towards the transition to the processing surface, which, starting from the previous course of the contact surface 11, curves towards the transport path T.
  • the ramp 12 guides the closure cap 3 in a direction X largely perpendicular to the course of the transport path T and moves it with respect to the path of movement of the support mandrel 5.
  • the closure cap 3 is in particular displaced so far that, when it later enters the processing path W, it moves with a the inner side of the casing arranged on the contact surface 11 rests on the support area 5.1 of the support mandrel 5 (not shown) and the rotational symmetry axis A has an offset Y with respect to the longitudinal axis B of the support mandrel 5.

  • the toothing 14 is designed in such a way that the teeth 14.1 can engage in the notches 3.6 of the casing outside 3.5 of the closure cap 3. When entering the processing section W, the teeth 14.1 come into engagement with the notches 3.6, with the result that the closure cap 3 rolls with its outer side 3.5 on the contact surface 13.
  • the support mandrel 5 and thus the driver 8 arranged on it have a predetermined rotational position M. Since the driver 8 and the stop 9 are in engagement when entering the processing path W, the closure cap 3 has an orientation of its rotational position that can be predetermined via the rotational position of the support mandrel 5. By appropriately controlling the rotational movement of the support mandrel 5, a desired rotational position of the closure cap 3 can thus be set. Since the closure cap 3 in the further course of the process in the processing path W inevitably rolls on the contact surface 13, a rotational position of the closure cap 3 about its center axis A in the processing path W is uniquely determined in each process position.
  • the cutting blade 6.1 of the cutting knife 6 is arranged and protrudes in the direction of the transport path T beyond the contact surface 13.

  • the rotational speed of the rotation D 'of the closure cap 3 in the processing section W is greater than the rotational speed of the rotational movement R of the support mandrel 5 and thus of the driver 8. Due to the difference in the rotational speeds, the stop 9 rotates faster about the central axis A of the closure cap 3 than the Driver 8 about the axis of rotation B. The stop 9 therefore lifts off from the driver 8, whereby the engagement of the driver 8 with the stop 9 is released.
  • Figure 10 shows a sectional view analogous to FIG Fig. 9 in a later process position when the closure cap 3 enters the cutting section S.
  • the entry of the closure cap 3 into the cutting section S corresponds to a first contact point of the jacket 3.1 of the closure cap 3 with the cutting blade 6.1 of the cutting knife 6. Since the cutting blade 6.1 protrudes in the direction of the transport path T over the contact surface 13, it can penetrate into the jacket 3.1 and make the cut.
  • the jacket 3.1 is supported by the support area 5.1 of the support mandrel 5, which is arranged opposite the cutting blade 6.1.
  • the cutting blade 6.1 can penetrate the jacket 3.1 and protrude into the grooves 5.2 arranged in the support area 5.1.
  • Figure 11 shows a sectional view analogous to FIG Fig. 10 in a later process position during the cutting process in the cutting section S.
  • the jacket 3.1 of the closure cap 3 is rolled onto the cutting blade 6.1.
  • the rotation D ′ of the closure cap 3 about its central axis A is clearly determined in the entire processing path W by the toothing 14 of the contact surface 13. In this way, the entire cut can be made in the closure cap 3 with a high degree of accuracy and in a predeterminable orientation of the latter.
  • the driver 8 can approach the stop 9 again in stages of rotation. It is therefore advisable to select a difference between the rotational speeds of the rotation D 'and the rotational movement R that is sufficiently large that the driver 8 does not collide with the stop 9 in the machining path W.
