Definitions

  • the field of application of the present invention is that of machines and methods for automatically capping containers.
  • the containers can be plastic containers intended to contain a plurality of discrete items, for example sweets such as candy, chewing gum, chocolates, biscuits, or food stuff in general.
  • the present invention also concerns a packaging line able to fill the containers with the discrete items and comprising the machine for capping the containers, after they have been filled.
  • Automatic packaging machines are known in the state of the art which are provided with devices able to cap containers previously filled with a plurality of items.
  • known devices comprise a plurality of mechanical members which pick up the caps and deposit them on the containers to be capped, where a suitable thruster element exerts a thrust force suitable to stably constrain the cap to the respective container, so as to close the latter.
  • the mechanical members as above typically comprise one or more rotatable members, each one rotating around a respective axis of rotation, for example conformed as star wheels provided with a plurality of seatings suitably shaped in order to temporarily hold the containers to be capped during the capping operation.
  • the containers are made to advance by the first wheel, which is driven in rotation according to a stepwise indexed movement.
  • a station for depositing the caps where these are rested on the containers, and, subsequently, a capping station where the caps are pressed by a thruster member against the mouth of the container, in order to close the latter.
  • anthropomorphic arms suitable to be used in the context of a piece of equipment for automatically capping containers are robots commonly used in the industrial automation sector and known as Delta robots, or robots called Scara (Selective Compliance Assembly Robot Arm).
  • the robots known in the state of the art comprise an articulated arm provided with several elements, articulated each with respect to the other according to the desired degrees of freedom, and supporting a tool, for example configured as a gripper, for picking up the caps, and depositing them on respective containers.
  • a tool for example configured as a gripper
  • Another disadvantage is it is a very complex configuration to control, because it would be necessary to coordinate the action of the different robots, in order to prevent reciprocal collisions, or collisions with other parts of the packaging machine.
  • One purpose of the present invention is therefore to provide a machine, and to perfect the corresponding method, for automatically capping containers, which, by overcoming the disadvantages of the state of the art, is fast and reliable, able to manipulate the caps at such a speed that it allows the automatic packaging line to reach high productivity values.
  • Another purpose of the present invention is to provide a machine, and to perfect the corresponding method, for automatically capping containers, which is more compact and less expensive than the solutions known in the state of the art.
  • Another purpose of the present invention is to provide a machine, and to perfect the corresponding method, for automatically capping containers, which is flexible, being able to manipulate different types of caps and requiring simple and rapid format change operations, which do not lead to long machine downtimes.
  • Another purpose of the present invention is to provide a machine, and to perfect the corresponding method, for automatically capping containers, which can be easily integrated into a packaging line so that it is possible to provide machine parts, such as for example the container transport line, which are suitable to interact with other work stations on the line, for example with a container filling station, so as to optimize the bulk, the number and disposition of the machine components, while also simplifying their structure.
  • machine parts such as for example the container transport line
  • other work stations on the line for example with a container filling station
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a capping machine for capping containers comprising a line to feed caps comprising at least one detection device configured to detect the position and/or the orientation of the caps on the feed line, a line to transport the containers, and an apparatus comprising a plurality of transport units, mobile with continuous rotary motion around a main axis of rotation, and a main actuator configured to drive the transport units in rotation around the axis as above, wherein the transport units are each configured to pick up a respective cap on the transport line and to deposit it on a respective container to be capped on the transport line.
  • each transport unit also comprises a gripping head able to be driven in rotation on itself, so as to be rotatably mounted around an axis of longitudinal development of the transport units.
  • the apparatus comprises at least two movement groups, each configured to move a first and second group of transport units according to an oscillating movement along a displacement directrix having at least one radial component with respect to the main axis of rotation, between a retracted condition, in which the transport units are closer to the main axis of rotation, and an extended condition, in which the transport units are more distant from the main axis of rotation; each movement group comprising a plurality of articulated movement devices each carrying a respective one transport unit in order to move the latter according to an alternate movement between the retracted condition and the extended condition.
  • the apparatus also comprises at least two motor members, each configured to drive a respective movement group in order to move the articulated movement devices as above so as to take the transport units in succession first into a pick-up position where the cap is picked up, and subsequently into a delivery position where the cap is delivered onto a respective container, in which the transport units are disposed respectively above a cap to be picked up and a container to be capped, substantially aligned vertically with them; wherein the pick-up and delivery positions of a cap are disposed, with reference to the radial component as above, between the retracted condition and the extended condition.
  • the capping machine comprises a programmable control and management unit, which is configured to control, in a coordinated manner, the movement of the apparatus with the movement of the feed line of the caps, and possibly with the movement of the transport line of the containers.
  • One advantage of the capping machine according to the present invention is that it is very flexible because the transport units can be advantageously taken into a position such that they are substantially aligned, in the pick-up position, with the caps to be picked up, and, in the delivery position, with the containers to be capped. Thanks to the control and command unit, the apparatus and the lines to feed the caps and to transport the containers are driven effectively and rapidly, in order to allow the capping machine to operate reliably and to reach high production rates.
  • the apparatus according to the present invention advantageously allows to adjust the movement of the transport units in order to easily adapt to caps and/or containers of the most varied formats.
  • the pick-up and delivery positions can be easily changed, since in order to change them it is sufficient to change the movement of the transport units (in particular, the trajectories and displacement speeds), for example in order to adapt to different operative conditions of the line to feed the caps.
  • Another advantage of the apparatus according to the present invention is that it is very compact, having a limited radial extension which allows to reduce its bulk.
  • Another advantage of the apparatus according to the present invention is that it does not require long and laborious format change operations. It is in fact sufficient to replace the gripping heads that grip the caps with another set of gripping heads having a shape mating with that of the format of the caps to be transported.
  • the transport units all rotate together around the main axis of rotation, for example according to a continuous motion with constant speed, all driven by the main actuator as above; however, with regards to the oscillating movement, the transport units of the first group are released in their movement from the transport units of the second group thanks to the independent motorization of the two groups, the former being for example in the retracted position, and the latter in the extended one.
  • the transport units comprised in the first group are disposed alternately with the transport units comprised in the second group, so that two consecutive transport units are constrained to a different movement group.
  • the movement groups as above are configured as an articulated quadrilateral.
  • Each transport unit extends along its axis of longitudinal development, which is substantially parallel to the main axis of rotation.
  • each transport unit comprises an actuator configured to move the gripping head of the caps which is mobile, in particular according to two different degrees of freedom, with respect to the transport unit itself.
  • the gripping head can both rotate around the axis of longitudinal development, and also translate linearly along the same axis.
  • the linear translation movement of the gripping heads allows them to be lowered toward the feed line of the caps and the transport line of the containers, both to pick up the caps and to deposit them on the containers, and to be raised - possibly together with the caps they hold - after the caps have been picked up and delivered.
  • the actuator allows the gripping head to exert the necessary thrust action that allows to constrain the cap in a stable and permanent manner to the respective container.
  • the gripping heads can rotate around the axis of longitudinal development of the transport unit that comprises them, they can advantageously rotate in order to angularly orient the seating able to receive the cap in accordance with the disposition of the cap on the feed line of the caps, a disposition which is detected before the cap arrives in correspondence with the pick-up position by suitable optical detection means.
  • the possibility that the gripping heads rotate around the axis of longitudinal development of the respective transport unit also advantageously means that the gripping heads are able to effectively manage the capping operation even if the caps are screw-on caps, because the rotation movement as above makes them suitable for screwing these caps on to the respective container.
  • the apparatus comprises pneumatic holding means to hold the cap, associated with the gripping heads, configured to exert a depression able to hold the caps.
  • an apparatus in accordance with the embodiments described above, cooperating with work stations disposed upstream and downstream of the apparatus, which are different from the feed and transport lines described above, possibly also in the context of an automatic machine different from the capping machine as above.
  • a method for capping containers, in particular by means of a capping machine in accordance with embodiments described above, in which it is provided to move the caps forward, individually fed, on a feed line, to detect the position and/or the orientation of the caps by means of a detection device, to drive a plurality of mobile transport units configured to each pick up one cap in a pick-up position, and to deposit them each in a delivery position on a respective container to be capped which is advancing on a transport line.
  • the step of driving the plurality of transport units allows to take them in succession firstly into the pick-up position of the cap and, subsequently, into the delivery position of the cap on a respective container, positions in which the transport units are disposed respectively above a cap to be picked up and a container to be capped, substantially aligned vertically with them.
  • the control and management unit of the capping machine before the driving step it is provided, by means of a control and management unit of the capping machine, to determine at least the position that the transport units will have to assume in the pick-up position as a function of the position of the cap that has been detected by means of the pick-up device, and possibly, after the control and management unit has calculated the instant in time when the transport unit will reach the pick-up position, to modify the feed speed of the caps on the feed line so that the cap to be picked up and the transport unit reach the pick-up position temporally coordinated with each other.
  • the driving step comprises:
  • the gripping head of the transport unit in correspondence with the pick-up position and the delivery position of the cap, respectively to pick up the cap individually fed by the feed line and to deposit it on a respective container advancing on the transport line, and subsequently, after having respectively picked up and deposited the cap, to raise the gripping head.
  • the transport unit moves at a speed correlated to the speed of advance of the feed line of the caps (for example, at a speed equal to the speed of advance of the conveyor belts that form the line), and that, in the delivery position of the cap, the transport unit moves at a speed correlated to the speed of advance of the transport line of the containers (for example, at a speed equal to the speed of advance of the line).
  • the relative speed between the transport units and the conveyor belts which move the caps forward is zero, at least at the moment the cap is picked up in correspondence with the pick-up position, and, similarly, the relative speed between the transport units and the transport line of the containers is zero, at least at the moment the cap is delivered in correspondence with the delivery position.
