Definitions

  • the present invention relates to packaging articles in carton containers which are obtained from tubular blanks.
  • the present invention relates to the device for collecting and erecting tubular blanks according to the preamble of claim 1.
  • Such a device is known, for example, from DE-A-22 50 667.
  • every blank is made of a sheet closed in a tubular form and folded in the regions of the creasing lines so as to define two overlapped parts; along an intermediate line, each of these overlapped parts features another creasing line parallel to the other ones.
  • the blanks are removed one by one from the bottom of a stack situated in a magazine, and transferred to a setup station equipped with fixed suction cups that attach themselves to one wall of the blank; the opposite wall is held by movable suction cups, carried by a rotary cantilevered frame that causes the blank erection.
  • suitable folder members fold the opposite flaps of the container bottom through an arc of 90°.
  • the blank is then set up by the above mentioned first collecting means cooperating in a first time with second collecting means, later with a strike arm and finally with third collecting means.
  • the blank is transferred from a collecting station to an erection station, in which two lateral walls of the blank are simultaneously held perpendicular to each other by the first and third collecting means, thus causing stabilisation of the blank shape.
  • An object of that solution is to carry out all the steps i.e. blank erection, folding of the flaps defining the container bottom, introduction of regular groups of articles and finally, folding of the flaps defining the container top, in a single container forming station.
  • the lowermost blank of the stack is collected by first collecting means equipped with suction cups carried by a rotary cantilevered frame.
  • Second collecting means cooperating with these first ones, are carried by a second rotary cantilevered frame and erect the blank.
  • the said first and second collecting means hold two lateral walls of the container, that are maintained perpendicular to each other.
  • the object of the present invention is to propose a device that withdraws and erect tubular blanks to form containers in a very simple way, with a structure of limited dimensions and working with high speed.
  • a cartoning machine 3 is equipped with the device for collecting and erecting tubular blanks 2, indicated with reference number 1.
  • tubular blanks 2 to be withdrawn and erected are fed in stacks to a collecting station 4 by conveying means 5, operated intermittently when each stack is near to finish; each stack of blanks is indicated with 2a.
  • the device 1 features a first collecting member 6 equipped with suction elements 7, like suction cups, that collect single tubular blanks 2 from the top of the stack 2a and transfer the withdrawn blanks to a conveying line 8, in the region of an erecting station 9.
  • the conveying line 8 is in longitudinal alignment with conveying means 5 that feed the tubular blanks 2, and is parallel to a line 10 that feeds the articles 11 to be introduced into the containers obtained from the blanks 2.
  • the articles 11 are carried to a station 2 (Fig. 4), in which groups of these articles 11 are formed and introduced inside the containers.
  • the station 12 is situated beside the station 9, in which the blanks 2 are erected.
  • the conveying line 8 includes two pairs of parallel belts 13 and 14, upper and lower, situated on vertical planes, one on side of the other. On their extremities, the belts 13,14 turn around respective pulleys 15,16.
  • Crosspieces 17,18 extend perpendicularly from the belts 13,14, and the pairs of upper belts 13 and lower belts 14 are operated simultaneously and intermittently, so that the corresponding lower run 13a and upper run 14a move in the same direction H (Fig. 1).
  • the collecting member 6 is controlled by a robotic equipment 19 that drives its movement along two perpendicular axes, on a vertical plane transversal to the conveying line 8.
  • the robotic equipment 19 features a vertical stem 21, the lower part of which carries a plate 22 supporting the suction cups 7; in fact the suction cups 7 are arranged, turned downwards, in the regions of the corners of the plate 22, that has e.g. a square shape.
  • the stem 21 is slidably inserted into a ring-like slide block 23 that features a groove set in engagement with a guide 24, of a known type, extending along a bar 25 (see Figs. 4 and 5), which is situated longitudinally over the said conveying line 8.
  • the device 1 features also, located in the region of the erecting station 9, a second collecting member 26 including suction cups 27, situated astride the lower belts 14 of the conveying line 8.
  • the suction cups 27 are supported by a plate 28 that is driven to move along a vertical axis by actuating means 29; in fact the suction cups 27 are arranged, turned downwards, in the regions of the corners of the plate 28, this latter having e.g. square shape (Fig. 2).
  • the collecting member 6 is situated over stack of blanks.
  • the collecting member 6 In order to withdraw the blank, the collecting member 6 is lowered so as to bring the suction cups 7 to contact the uppermost blank 2 of the stack 2a, in the position indicated with the sketched line 6a in Fig. 1.
  • Subsequent raising of the collecting member 6 causes correspondent raising of the said blank.
  • the lowering and raising of the collecting member 6 are determined by the vertical sliding of the stem 21 of the robotic equipment 19: during these movements the pairs of belts 13, 14 are motionless.
  • the collecting member 6 is lowered again so as to carry the withdrawn blank 2 to contact the second collecting member 26, the suction cups 27 of which, in this step, are moved by the actuating means 29 over the surface defined by the upper run of the belts 14 (Fig. 2).
  • the second collecting member 26 holds the blank 2 to be erected by attachment to a lower part that is designed to form a wall of the container that is opposite to the one defined by the upper part, which the first collecting member 6 grasps.
  • the blank assumes the parallelepiped shape of the container 20.
  • this container 20 is opened and the container is ready to be filled with groups of articles 11 formed in the station 12 (see also Figs. 4 and 5).
  • the blank is kept by the said collecting members 6,26 that allow to avoid folding of the container also when the same blank is made of recycled cardboard and the like.
  • the distance between the belts 13 and 14 of the conveying belt 8 is suitably than the height of the container 20 so as not to interfere with the erecting of the same container.
  • the collecting members 6 and 26 release the opposite walls of the container 20.
  • the container 20 filled with the articles 11 is moved forward by the belts 13,14 of the conveying line 8, moved simultaneously in opposite directions.
  • the crosspieces 17,18 of the belts 13,14 engage the container 20.
  • the movement of the container in direction H determines engagement of folder elements 30, situated downstream of the erection station 9 according to the movement direction of the conveying line 8.
  • These folder elements 30 close the opposing flaps of the bottom and the top of the container 20.
  • the proposed device withdraws, in a very simple way, blanks from a stack fed to the cartoning machine and erects the same blanks in order to obtain containers therefrom.
  • the robotic equipment 19 moves the collecting member 6 along two perpendicular axes, more precisely, on a vertical plane parallel with respect to the conveying means 5 and to the conveying line 8; this is possible due to the fact that the said conveying means 5 and the conveying line 8 are in longitudinal alignment.
