Definitions

  • the invention relates to a container plate for supporting and positioning a container in a treatment machine according to the preamble of claim 1.
  • Spring-loaded container plates are used in particular on treatment machines of the rotary type for treating containers and allow the containers to be lowered into a centering ring of the container plate during the treatment process, for example labeling or direct printing, and thereby guide the containers precisely and reliably during treatment.
  • the suspension facilitates horizontal container transfer via the centering ring and thus simplifies the construction in the infeed and outfeed of the treatment machine.
  • the container plates are usually adapted to the container format to be processed and may have to be replaced when the format is changed. For this purpose, it is known to detach and exchange the container plates as a whole from the associated rotary drives. Furthermore, it is known for container plates that are not spring-loaded to attach format-specific centering rings magnetically to the base of the container plate, so that the centering rings can be easily exchanged when the format changes.
  • the task is solved with a container plate according to claim 1. Accordingly, this serves to support and position a container, in particular a bottle, in a treatment machine.
  • the container plate comprises a base that can be rigidly coupled to a rotary drive and a centering unit seated thereon with a centering ring for centering the container on the bottom side and with a support plate for the bottom of the container that is movably mounted toward the rotary drive and elastically restored in the opposite direction.
  • the centering unit is designed as a set-up element that can be detached from the base without tools in the sense of a set part.
  • the spring-loaded base can be used for different container formats and with one Format changes remain on the respective treatment machine.
  • the centering unit with the format-dependent centering ring and the axially movable support plate can be kept available for the different container formats at comparatively low cost and can be quickly replaced.
  • the base preferably comprises a lower part that can be rigidly coupled to the rotary drive and an upper part that is mounted so that it can move axially with respect to the rotary drive and is elastically restored away from the lower part, for supporting the support plate.
  • the upper part can thus be regarded as a bearing plate, which is spring-loaded axially towards the base, for the support plate of the centering unit.
  • the base comprises at least three guide columns for the axial linear guidance of the upper part with respect to the rotary drive and upper mechanical stops limiting the return of the upper part are formed on the respective guide column.
  • the upper mechanical stops preferably prevent the support plate and/or the upper part from striking the underside of the centering ring. This avoids the centering ring magnetically attached to the lower part being unintentionally detached by the elastic return of the upper part or the support plate sitting on it.
  • the upper mechanical stops prevent the upper part from detaching from the lower part.
  • the upper axial stroke of the upper part is limited by the mechanical stop. Accordingly, a lower mechanical stop can be formed on the guide columns in order to limit the axial stroke downwards.
  • the axial stroke can be limited downwards by means of at least one stop element arranged and used in particular between the lower part and the upper part.
  • This can be formed on the lower part or upper part or attached rigidly and can preferably be exchanged for a specific format.
  • stop bodies are made of plastic, for example, and/or marked in color depending on the permitted axial stroke, ie depending on the stroke length.
  • Compression springs are then preferably arranged between the lower part and the upper part, which reset the upper part upwards and which are under compressive stress between the upper and lower mechanical stop, ie in every axial position of the upper part.
  • the guide pillars or the centering ring have permanent magnets for attaching the centering ring magnetically to the base so that the centering unit can be attached without tools. This magnetic fastening prevents the centering unit from becoming detached upwards unintentionally during operation and also secures its rotational position in relation to the base.
  • the centering ring then has correspondingly designed ferromagnetic areas, or the guide columns are ferromagnetic at least at their upper ends.
  • the centering unit preferably includes connecting bolts which couple the support plate to the centering ring in an axially movable manner.
  • the support plate is guided by the connecting bolt and secured against falling when the centering unit is detached by means of a lower stop.
  • the connecting bolt then sits rigidly on the centering ring, which also acts as an upper stop for the support plate.
  • the container plate 1 comprises in a preferred embodiment a base 2 that can be coupled to a rotary drive (not shown) with a lower part 3 that can be rigidly coupled to the rotary drive and an upper part that is mounted so that it can move axially with respect to the axis of rotation 1a of the container plate and is elastically restored away from the lower part 3 4.
  • the container plate 1 comprises a centering unit 5 which is rigidly fastened to the base 2 and has a centering ring 6 for centering the bottom of a container (not shown) and a support plate 7 for the bottom of the container which is movably mounted towards the base 2 and is elastically restored in the opposite direction.
  • the base 2 also includes at least three guide columns 8 for the axial linear guidance of the spring-loaded upper part 4.
  • the centering ring 6 is magnetically fixed/attached to the guide columns 8.
  • permanent magnets 9, for example are integrated into the centering ring 6, assigned to the end faces of the guide columns 8, for example by means of an adhesive layer 10.
  • the guide columns 8 are then made of a ferromagnetic material, at least on the front side, in particular a magnetic high-grade steel.
  • the guide columns 8 could include permanent magnets 9 arranged on the face side at their upper ends for magnetically attaching the centering ring 6 to the lower part 3 of the base 2 (not shown).
  • the Centering ring 6 would then be integrated with the permanent magnets 9 correspondingly arranged ferromagnetic inserts such as metal plates or the like (at the point of the adhesive layer 10).
  • a magnetic fixation of the centering unit 5 on the base 2 is provided, which both secures the centering unit 5 during operation against axial lifting and twisting with respect to the base 2 and at the same time enables the centering unit 5 to be detached manually from the base 2 without tools.
  • the container plate 1 preferably comprises compression springs 11, which are permanently under compressive stress between the lower part 3 and the upper part 4 when the container plate 1 is in the assembled state.
  • the guide columns 8 have an upper stop 8a and a lower stop 8b, which limit an axial stroke 12 (stroke length) of the upper part 4 with respect to the lower part 3 at the top and bottom. As illustrated, the lifting range between the upper and lower stops 8a, 8b can be achieved in a simple manner by reducing the cross section 8c of the guide columns 8.
  • the centering unit 5 also includes connecting bolts 13 which couple the support plate 7 to the centering ring 6 in an axially movable manner.
  • the connecting bolts 13 comprise a lower stop 14 for the support plate 7 embodied, for example, as a mushroom head, and can be screwed or glued into the centering ring 6 at their opposite end. As a result, the support plate 7 cannot fall off the centering ring 6 and is also guided in a rotationally fixed manner in this respect and can be moved axially with a stroke 15 .
  • lower stops 14 would also be conceivable, for example in the form of at least one groove (not shown) running externally on the centering ring 6 or other structures coupling the centering ring 6 and the support plate 7 to one another in an axially movable manner.
  • the upper part 4 of the base 2 then has corresponding recesses 16 with the connecting bolts 13, as also in FIG 3 with a connecting bolt 13 arranged therein.
  • the centering unit 7 can additionally comprise an alignment element 17, which is designed here, for example, approximately in the shape of a horseshoe.
  • the alignment element 17 then engages around a container to be positioned in a form-fitting manner at its periphery in order to enable alignment in a rotational position-compliant manner during the treatment.
  • the alignment element 17 then comprises at its base, for example, at least one alignment bolt 17a, which engages in an associated recess 18 in the upper part 4 of the base 2 in a form-fitting manner.
  • the upper part 4 has a recess 4a in the region of the guide columns 8, which enables the support plate 7 to deflect easily with the upper part 4 supporting it.
  • an optional central support element 20 is also shown, which serves to support the bottom of the container to be treated.
  • the support element 20 is rigidly attached to the lower part 3 of the base 2 . If the optional support element 20 is missing, the support plate 7 is preferably designed as a continuous surface toward the axis of rotation 1a, ie without the Figures 1 to 3 shown opening for the support element 20.
  • the centering ring 6 comprises a centering phase 6a running around the circumference, the function of which is known in principle and is therefore not explained in more detail in this context.
  • the maximum axial stroke 12 specified by the upper and lower stops 8a, 8b of the guide columns 8 could be reduced, for example, by clipping in spacer rings or similar elements and thus easily adapted to a specific container format.
  • a maximum possible stroke 12 of 5 mm has proven itself, which could be reduced to 3 mm, for example, for individual container formats. This also enables the format of the container plate 1 to be easily adapted to different container types.
  • the maximum axial stroke 12 (the stroke length) can be limited downwards by at least one stop body 21 inserted between the lower part 3 and the upper part 4, see FIG figure 1 .
  • One or more such stop bodies 21 can be formed, for example, on the lower part 3 and/or upper part 4 or can be rigidly fastened in a conventional manner.
  • the stop bodies 21 can be provided as a set and optionally exchanged format-specifically on all container plates 1 to be used.
  • the stop bodies 21 are made of plastic, for example, and/or are marked in color depending on the permitted axial stroke 12 .
  • the stop bodies 21 enable high axial pressure forces, for example for torsionally rigid entrainment of attached containers.
  • both the centering ring 6 and the support plate 7 can in principle be designed both for rotationally symmetrical containers, as shown, and for containers with a non-rotationally symmetrical cross section, ie so-called shaped bottles. Only the circumferential course of the centering phase 6a would be suitable for this to adapt to the respective container format and/or to arrange an alignment element 17 shaped to match on the centering ring 6 .
  • Coupling elements formed on the lower part 3 of the base 2 for non-rotatably coupling the container plate 1 to a rotary drive (not shown).
  • a rotary drive for example, there is a central stub shaft 2a and at least one driving pin 2b.
  • the coupling could be designed in such a way that the container plate 1 as a whole, including the base 2, can be detached from the respective rotary drive without tools.
  • a quick-release fastener of a known design can be present for this purpose (not shown). This would be advantageous if the container cross-section is too large for the base 2 and the container plate 1 therefore has to be replaced overall depending on the format.
  • appropriately adapted centering units 5 can be kept available for different container formats in a comparatively cost-effective and space-saving manner and can also be attached to the respective treatment positions of an associated container treatment machine on the bases 2 in the event of a format change with little outlay in terms of equipment and personnel.
  • the container plates 1 are therefore preferably part of a treatment machine (not shown) for treating, in particular labeling or direct printing, bottles or similar containers and for this purpose arranged in a manner known in principle distributed evenly around the circumference of a continuously rotating container carousel of the container treatment machine.
  • the container plates then each correspond to a treatment position of the treatment machine and are arranged to rotate on a rotary drive that is present there, for example a servomotor with a corresponding drive shaft.
