Definitions

  • the present invention generally refers to the handling of rods, and specifically concerns a method for loading rods into a loading station, for example, into a hopper.
  • the invention concerns an apparatus for loading rods into a loading station.
  • filter rods made of cylindrical rods of filter material, usually cellulose acetate, having a predetermined length are used. Filter rods are intended to be cut in a transverse direction to form filters that are applied to cigarettes.
  • the filter rods are produced in a machine having an outlet station in which the finished filter rods are arranged parallel to each other within cardboard boxes having an open front and upper side.
  • Full boxes are generally unloaded manually and are closed by applying a cardboard strip along the open upper edge and a cardboard cover on the open front face.
  • the closed boxes are then placed on pallets and transported to a warehouse to undergo a certain curing period, the duration of which depends on the type of filter, and which can vary from a few minutes to a few hours.
  • the boxes are taken from the warehouse and transported close to a loading area in which a feeder device is arranged with a hopper configured for receiving the filter rods.
  • the boxes are opened manually on two sides (upper side and front face) and are placed on a tipper, which overturns the boxes and pours the filter rods into the hopper of the feeding device.
  • the filter rods are poured into the hopper of the feeding device by overturning the boxes and making the filter rods fall from above into the upper mouth of the hopper. In this step the filter rods may become askew and may cause jamming of the feeder device and machine downtimes.
  • the present invention aims to provide a method for loading rods into a loading station which solves the problems of the prior art.
  • this object is achieved by a method having the characteristics forming the subject of claim 1.

  • the extractor device 72 may also grip a container 10 and may be used to transfer full containers 10 from the waiting station 48 to the emptying station 42, and empty containers 10 from the emptying station 42 to the waiting station 48.
  • the apparatus 40 previously described is configured to implement a method for loading an assembly 12 of rods 14, in particular rods 14 for producing smoking articles, comprising a step of gripping the assembly 12 by gripping means 76, and a release step of said assembly 12 in a loading station 78, wherein in said assembly 12 said rods 14 have respective longitudinal axes parallel to each other and parallel to a horizontal plane, wherein said gripping means 76 clamp said assembly 12 between two gripping planes parallel to each other, and carry said assembly 12 into the loading station 78 while maintaining the longitudinal axes of said rods 14 parallel to said horizontal plane.
  • the operation of the apparatus 40 is as follows.
  • the full containers 10 are taken from the warehouse in which they have spent the prescribed curing period and are transported towards the apparatus 40 by the conveyor 44.
  • the robot 46 picks up the container 10 on the conveyor 44 and deposits it in the waiting station 48.
  • the extractor device 72 grabs the container 10 located in the waiting station 48 by means of the gripping member 74 and transfers it to the emptying station 42.
  • the blocking device is activated which, by means of the clamps 52, locks the bottom wall 18 of the frame 16 in the emptying station 42.
  • the first manipulator device 56 is activated which, through the actuators 58, brings the gripping members 60 into contact with the respective front covers 22, 24.
  • the gripping members 60 grip the front covers 22, 24 by suction or mechanical grippers and are then moved away from the frame 16 so as to detach the front covers 22, 24 from the frame 16.
  • the gripping member 74 of the extractor device 72 is positioned in the emptying station 42 so that the two vertical plates 76 in the open position are located on opposite sides of the assembly 12 of rods 12. Then, the two vertical plates 76 are brought into the closed position so that the two vertical plates 76 abut in the horizontal direction against opposite ends of the assembly 12 of rods 12 as illustrated in Figure 8 .
  • the two vertical plates 76 in the closed position hold the assembly 12 of rods 14.
  • the two vertical plates 76 may be provided with a protruding lower edge to form support surfaces for the ends of the rods 14 forming the lower layer of the assembly 12. Protruding edges may also be provided along the vertical sides of the vertical plates 76 to retain the vertical edges of the assembly 12 of rods 14.
  • the second manipulator device 64 brings the gripping member 68 into engagement with the upper closing element 26 and removes the upper closing element 26 in the vertical direction from the frame 16.
  • the gripping member 74 of the extractor device 72 may be configured so as to leave a free space between the vertical plates 76, which allows the passage in the vertical direction of the upper closing element 26.
  • the gripping member 74 of the extractor device 72 is moved in a vertical direction so as to extract the assembly 12 of rods 14 from the frame 16 in a vertical direction, which remains retained in the emptying station 42 by the blocking device 50.
  • the extractor device 72 moves the gripping member 74 with the assembly 12 of rods 14 held between the two vertical plates 76 and inserts the two vertical plates 76 and the assembly 12 of rods 14 inside a loading station 78 formed, for example, by a hopper.
  • the gripping member 74 of the extractor device 72 can rotate by 90° between the extraction position of the assembly 12 and the insertion position of the assembly 12 into the hopper 78.
  • the assembly 12 of rods 14 is inserted into the hopper 78 until a lower side of the assembly 12 of rods 14 is brought into close proximity to the rods 14 already contained inside the hopper 78. In this way, the free fall distance of the rods is as short as possible. The free fall distance of the rods 14 into the hopper 78 can be reduced to substantially zero.
  • a particularly relevant aspect of the solution according to the present invention is that the assembly 12 of rods 14 is always retained throughout the entire process.
  • the assembly 12 continues to be held by the upper closing element 26 which holds the assembly 12 in the frame 16 by compression.
  • the two vertical plates 76 of the extractor device 72 grip the assembly 12 while this is still held in the frame 16 by the upper closing element 26.
  • the upper closing element 26 is only removed after the assembly 12 has already been gripped by the two vertical plates 76 of the extractor device 72. Therefore, the assembly 12 is retained in a positive way until it is inserted into the hopper 78.
  • the first manipulator device 56 can apply the front covers 22, 24 to the frame 16, and the second manipulator device 64 can apply the upper closing element 26 to the frame 16 as illustrated in Figure 11 , so that an empty container 10 is assembled in the emptying station 42.
  • the extractor device 72 may grip the empty container 10 located in the emptying station 42 by means of the gripping member 74, and can transfer the empty container 10 to the waiting station 48.
  • the robot 46 may pick up the empty container 10 in the waiting station 48 and transfer it to an outlet conveyor and then load a full container 10 into the waiting station 48 for a new cycle.
  • the robot 46 could pick up the empty container 10 directly in the emptying station 42 and transfer it to the outlet conveyor.
  • the robot 46 could also transfer the full container 10 from the conveyor 44 to the emptying station 42 avoiding the passage through the waiting station 48.
