Definitions

  • the present invention relates to an apparatus and method for packaging products, in which the products to be packaged are placed inside a box according to a predefined ordered configuration.
  • the present invention preferably applies, though not exclusively, to the sector of preparing and packaging products for food use or not, an example of which is represented by capsules for brewing beverages, such as coffee, a product to which reference will be made hereinafter without losing generality.
  • packaging apparatuses are known in which a plurality of empty capsules are individually filled with the product to be packaged, such as coffee powder, and then, after being closed by an appropriate membrane, are sent to the final steps of packing into boxes and packaging.
  • the packing step often provides placing the capsules inside the boxes according to a predefined ordered configuration, so as to optimise the space occupied by the capsules inside the boxes, as well as to give the final package a neat and tidy appearance which is generally appreciated by customers.
  • product means any object within an industrial production line that can be picked up, moved and deposited in a box.
  • the products are preferably equal to each other, but may also differ in some characteristics such as form, composition or colour.
  • Products can be, for example, food or sweets already packaged in individual containers or wrappers, such as coffee capsules or other brewing beverages, bottles and cartons of beverages, yoghurt pots, individual chocolates (wrapped or naked), candies, small boxes, pouches containing solid, liquid or semi-solid food products; also, ceramic industry products, sanitary napkins, products of the tobacco industry, cosmetic industry products, pharmaceutical industry products, personal & home care industry products.
  • food or sweets already packaged in individual containers or wrappers such as coffee capsules or other brewing beverages, bottles and cartons of beverages, yoghurt pots, individual chocolates (wrapped or naked), candies, small boxes, pouches containing solid, liquid or semi-solid food products; also, ceramic industry products, sanitary napkins, products of the tobacco industry, cosmetic industry products, pharmaceutical industry products, personal & home care industry products.
  • box means any container suitable for containing products, in particular any container suitable for packaging products to be subsequently marketed.
  • the box is intended to contain a plurality of products in an ordered configuration.
  • the box is preferably made of cardboard and is provided with a closable lid, however other configurations and materials can be provided.
  • Configuration of a plurality of products means the arrangement of the products in space, referring in particular to their mutual positioning and orientation in space.
  • a configuration is said to be “ordered” when the products, in a certain position of the packaging apparatus, maintain a predefined spatial arrangement, preferably constant over time.
  • one or more “columns” of products and/or one or more “rows” of products may be identified, where a “column” of products is defined as a plurality of products aligned with each other substantially parallel to the advance direction, and a “row” of products is defined as a plurality of products aligned with each other substantially perpendicular to the advance direction.
  • the advance direction may be essentially rectilinear or curved.
  • a “guide” is a mechanical device arranged to allow the products therein to slide between an inlet section and an outlet section along an essentially linear path, which, in turn, may be rectilinear or curved and may extend in a plane or in space.
  • the guide extends in a prevailing longitudinal direction, which allows to define a longitudinal axis of the guide and defines the linear path of the articles between the starting and finishing sections.
  • the guide is a static mechanical member.
  • the guide is configured to accommodate and guide therein a single row of products and to maintain the products in a spatial orientation which is fixed with respect to the guide, as they move along the linear path.
  • the products slide along the guide by the force of gravity, however it is also provided that such sliding is caused or favoured by other external forces such as air jets or drive belts.
  • a guide (or a tract thereof) may be rotated about its longitudinal axis in a substantially progressive manner.
  • the orientation of the cross-section of the guide varies as the position along its longitudinal axis changes, so that each cross-section is angularly offset from the sections immediately preceding or following it.
  • the rotation of the guide about its own longitudinal axis may be constant along its longitudinal axis, i.e. the angular offset between cross-sections remains constant with the same distance along the longitudinal axis, or it may be variable.
  • the rotation of the guide may also change direction or, for small portions of the guide, be zero.
  • the overall rotation of the guide around its longitudinal axis between the inlet section and outlet section is quantified by a “rotation angle”, which is preferably expressed in minimum terms between 0° and 360°.
  • the rotation angle is expressed without taking into account any full 360° rotations, which in fact have no effect on the orientation of the products, so that, for example, a rotation angle of 60° also corresponds to a generic rotation angle of 60° + n* 360° (with n being an integer).
  • the Applicant firstly observed that products often have to be deposited inside a box in an ordered configuration which is different from the one in which they are discharged from a production line.
  • the Applicant has also ascertained that the maximum compaction requirements, often inspiring the ordered configuration of the products inside a box, hardly combines with the requirements related to the production steps.
  • the Applicant observed that, in the production step, an ordered configuration of the products, wherein the latter are suitably spaced and uniformly oriented, is preferred, whereas in the packing step, an ordered configuration, wherein the products are placed next to each other and sometimes also oriented differently, is preferred so as to minimise their overall encumbrance, and consequently, also the size of the box in which they are packaged.
  • coffee capsules have a tapered form from the head towards the base (typically truncated-conical shape) which can be easily compacted inside a box by inclining the capsules with respect to each other.
  • the capsules are all oriented in the same way: for example, in a particularly widespread production plant, it is provided that the capsules are moved between the various workstations on multi track conveyors where the capsules are arranged in parallel rows, spaced out from each other, and are all oriented with their heads upwards so as to facilitate the step of filling them with coffee powder and subsequently positioning and sealing the closing membrane of the capsule .
  • the Applicant therefore felt the need to simplify the operation of preparing the products to be packed in order to significantly reduce the resources and costs associated with this operation.
  • a guide arranged to accommodate therein a product adapted to slide can accurately determine not only the discharge position of that product but also its orientation in space.
  • the Applicant has finally found that, by sliding a plurality of products between a supply station and a discharge station within respective guides, each configured to lead such products along its longitudinal axis and to rotate them at the same time about its longitudinal axis through a suitable rotation angle, it is possible to obtain a very wide range of configurations of products being discharged from the guides without any need to rely on complex and expensive handling members.

  • said products being discharged from said at least one first and one second guides are arranged in said discharge station in a second configuration, different from said first configuration.
  • the guides are static mechanical parts, which are absolutely cost-effective and easy to manufacture.
  • a further advantage of this invention derives from the fact that, thanks to the very low manufacturing cost, it is possible to have several sets of guides, interchangeable with each other, so that the guides can be quickly replaced in the event of any changes in the packing configuration or adapted to any changes in products.
  • the guides may be used effectively even by simply using the force of gravity, with no need to supply energy from outside for moving and re orienting the products.

  • the pick-up device 7 takes a plurality of capsules 2 from the conveyor 5 after they have been appropriately filled with coffee powder and closed with a membrane
  • the gripping head 8 is then raised by the arm 9 until it is at the height of the supply station 11 (Fig. 2), rotated through 90° so as to align the gripping elements 8a with the channels 15 (Fig. 3), moved over the plate 14 and finally lowered to deposit the capsule 2 into the channels 15 of the plate 14 (Fig. 4).
  • the capsules 2 are then moved along the advance direction X in respective columns B to the inlet of the guides 12 where they are engaged at the protruding edges 2c in the grooves 19 of the side retaining walls 18.
  • the capsules 2 then slide by gravity along their respective guides 12 and, during this sliding movement, are also rotated relative to the longitudinal axis of the guide in which they are accommodated through the first or second rotation angle.
  • the capsules being discharged from the guides 12 then assume the second configuration described above, which is equal to the desired configuration for packing them as shown in Figure 6.
  • Each row of capsules being discharged from the guides 12 is then taken by one of the gripping devices 16 and carried by the carousel 17 to a box 3, formed and opened, retained by an equipment 22 of the carousel 21, within which it is deposited.
  • the box 3, containing the capsules arranged in the desired configuration, is then closed at the following box closing station and deposited on the transporter 30, which provides to bring it to the following stations.
  • the packaging apparatus 1 therefore allows to arrange the products being discharged from a production line according to a variety of configurations in a simple and cost-effective manner.
  • the configuration of the capsules being discharged from the guides can easily be varied by changing the form of the individual guides, depending on the specific arrangement required for packing the capsules 2.
  • Figures 9 to 11 show this second embodiment.
  • Figure 9 shows the desired packing configuration of the capsules 2, in which the capsules are all inclined by an angle T equal to 90° with respect to the reference plane P, while Figures 10 and 11 show the repositioning and re-orientation movement to which each individual column of capsules 2 is subjected within the respective guide 12.
  • each row A of capsules being discharged from the supply station is reconfigured into a row A” corresponding to the desired packing configuration shown in Figure 9.
