Definitions

  • the present invention relates to a method of feeding elements of sheet material to a product wrapping line.
  • the invention finds application to advantage in the tobacco industry, where the wrapping line of a packaging machine, typically a cigarette packer or cartoner, is supplied with slips of sheet material consisting in particular of “plain” coupons that appear as a single leaf, or “folded” coupons that present at least two mutually overlapping portions connected along one side; direct reference is made to this same field in the following specification, albeit with no limitation implied.
  • the coupons are drawn from a supply which, in view of the size and architecture of the packer or cartoner, is located at a given distance from the assembly station.
  • the coupons are directed from the supply to the assembly station along a transfer line by a conveying element that retains the single coupons by suction and feeds them in succession to the station, synchronously with the operation of the wrapping devices.
  • a further drawback stems from the fact that, in order to avoid contact with the wrapping devices, the conveying elements in question must necessarily release the coupons at a given distance short of the aforementioned assembly station; this means that the coupons are effectively pitched into the station and their flight is difficult to control.
  • the object of the present invention is to provide a conveying method that will allow both plain and folded coupons to be transferred with no problems whatsoever.
  • the stated object is realized according to the present invention in a method for feeding elements of sheet material to a product wrapping line, whereby elements of sheet material are conveyed from a supply station to an assembly station and united with relative products, comprising at least the step of pushing the elements of sheet material along a predetermined transfer line and through a predetermined distance into the assembly station.
  • the aforementioned object is realized similarly in a unit according to the present invention for feeding elements of sheet material to a product wrapping line, by which elements of sheet material are conveyed from a supply station to an assembly station and united with relative products; the unit disclosed is equipped with pushing means such as will direct the single elements of sheet material along a predetermined transfer line and through a predetermined distance into the assembly station.
  • FIG. 1 illustrates a unit embodied in accordance with the present invention for feeding elements of sheet material to a station of a packaging machine at which they are assembled with relative products, viewed schematically in perspective with certain parts omitted;
  • FIG. 2 shows the unit of FIG. 1 in a schematic plan view, with certain parts omitted;
  • FIG. 3 shows the unit of FIG. 1 in a schematic side elevation, with certain parts omitted;
  • FIG. 4 shows an enlarged detail of the unit in FIG. 1 and FIG. 3, viewed schematically and in perspective;
  • FIG. 5 shows a detail of FIG. 3, viewed schematically and in perspective
  • FIGS. 6 and 7 show a detail of FIG. 1, viewed schematically and in perspective and illustrated in two successive operating steps.
  • FIG. 1 of the drawings denotes a unit, in its entirety, for feeding elements 2 of sheet material to a packaging machine of which the drawings show a wrapping line 3 .
  • the elements 2 of sheet material present a substantially rectangular outline and consist in coupons of either “plain” or “folded” type, which are drawn from a supply 4 serving as a distribution station and consisting in a stack 5 of the elements 2 of sheet material.
  • the elements 2 are taken up by respective feed means 6 and placed at the infeed end of a transfer line 7 extending along a substantially horizontal first feed path P1 toward an assembly station 8 located at the entry point of the wrapping line 3 .
  • This same assembly station 8 is in receipt of substantially parallelepiped products 9 , appearing in the example of the drawings as single packets of cigarettes 10 ordered into groups and directed thus along a second feed path P2 substantially parallel to the first feed path P1.
  • the products 9 and the relative wrapper blanks 12 are brought together at the assembly station 8 , positioned one facing another transversely to the wrapping line 3 .
  • the feed means 6 comprise a rocking arm 15 anchored pivotably at one end to a shaft 16 of which the axis 17 extends parallel to the first feed path P1, mounted to a frame 18 and capable thus of angular movement about the axis 17 through the agency of a first motor 19 connected to the shaft 16 by way of a mechanical linkage 19 a (FIGS. 2 and 5), between a first raised position indicated by solid lines in FIG. 3, and a second lowered position indicated by phantom lines in FIG. 3.
  • the free end of the arm 15 carries a pneumatic holder 20 mounted to a respective shaft 21 of which the axis 22 extends parallel to the axis 17 first mentioned.
  • the holder 20 consists in a block 23 keyed to the free end of the shaft 21 and equipped with a plurality of suction cups 24 able to attract and retain the elements 2 of sheet material.
  • the rocking arm 15 incorporates a first drive 25 comprising a wheel 26 mounted rotatably to the one shaft 16 and fixed relative to the frame 18 , also a pulley 27 (FIG. 4) keyed to the other shaft 21 and free to rotate relative to the arm 15 .
  • a first drive 25 comprising a wheel 26 mounted rotatably to the one shaft 16 and fixed relative to the frame 18 , also a pulley 27 (FIG. 4) keyed to the other shaft 21 and free to rotate relative to the arm 15 .
  • the same first drive 25 also comprises a belt 28 , looped around the wheel 26 and the pulley 27 and tensioned by a jockey roller 29 .
  • the arrangement of the drive 25 is such that in operation, when the shaft 16 is made to rotate (clockwise in FIG. 3) by the first motor 19 about the relative axis 17 , which lies remote from the plane occupied by the element 2 of sheet material, the wheel 26 remains stationary whilst the arm 15 is caused to rock, and the resulting movement induced in the belt 28 thus causes the pulley 27 to rotate (counterclockwise in FIG. 3) about the corresponding axis 22 , which lies substantially parallel to the plane occupied by the element 2 of sheet material.
  • the function of the wheel 26 is to determine the orientation of the block 23 relative to the corresponding axis 22 whenever the shaft 16 is set in rotation.
  • the pulley 27 being keyed to the shaft 21 as mentioned previously, causes the block 23 also to rotate in the same counterclockwise direction and to move, as the arm 15 rotates, from the position illustrated by solid lines in FIG. 3, in which the suction cups 24 actively engage the bottom of the stack 5 , to the position illustrated by phantom lines in FIG. 3 in which the element 2 of sheet material is positioned vertically over the transfer line 7 .
  • the feed means 6 also include take-up and insertion means 30 serving to carry out a final step of transferring the elements 2 of sheet material from the suction cups 24 into a guide channel 31 extending along the feed path P1 followed by the transfer line 7 .
  • the take-up and insertion means 30 comprise a first pair of rollers 32 mounted to the opposite ends of a shaft 33 extending parallel to the first path P1, carried between a pair of uprights 34 supported on the frame 18 , and a second pair of rollers 35 mounted freely to respective pivots 36 carried by the selfsame uprights 34 and operating in conjunction with the first rollers 32 in such a way as to take up the element 2 of sheet material from the suction cups 24 , with the aid also of a chute denoted 37 , and insert it into an infeed end of the guide channel 31 .
  • the channel 31 presents a profile substantially of “U” shape when seen in section, composed of a front side wall 38 , a bottom track 39 and a rear side wall 40 (FIGS. 1 and 2), extending from the infeed end through a predetermined distance as far as the assembly station 8 , of which the front side wall 38 affords a slot 41 disposed parallel to the first feed path P1.
  • the element 2 of sheet material occupies the guide channel 31 with a first edge 2 a disposed perpendicular to the bottom track 39 of the selfsame channel, addressing the infeed end, and a second edge 2 b in contact with the track 39 .
  • the unit 1 comprises pushing means 42 positioned alongside the guide channel 31 , such as will maneuver each element 2 of sheet material along the transfer line 7 from the infeed end of the channel 31 to the assembly station 8 .
  • the pushing means 42 in question include conveyor means 43 , describing and capable of movement along a closed path comprising a forward leg that extends the full length of the channel 31 .
  • the conveyor means 43 incorporate a belt 44 looped around two pulleys of which one, denoted 45 , is positioned at the infeed end of the channel 31 and mounted to the vertically disposed shaft 46 of a second motor 47 , and the other, denoted 48 , is positioned near the assembly station 8 and mounted to a shaft 49 disposed parallel to the shaft 46 of the motor 47 .
  • the looped belt 44 is furnished with pushing elements appearing as equispaced projections 50 , and disposed with one branch 51 , extending along the aforementioned forward leg of the looped path, that runs breasted with and along the slot 41 in such a way that the projections 50 are able to pass internally of the channel 31 .
  • the pushing elements afforded by the projections 50 are set in motion cyclically between a position of interception and contact with the aforementioned first edge 2 a of an element 2 positioned at the infeed end of the guide channel 31 , and a position coinciding substantially with the assembly station 8 , at which the element 2 is released when contact between the projection 50 and the first edge 2 a of the element 2 ceases.
  • rollers 32 are set in rotation by the first motor 19 , independently of the second motor 47 , through the agency of a second drive denoted 52 , and (referring to FIGS. 1, 6 and 7 ) that the assembly station 8 is equipped with a push rod 53 reciprocating along the fourth path P4 and serving to advance each product 9 together with a relative wrapper blank 12 , between which an element 2 of sheet material is inserted transversely to the wrapping line 3 .
  • Entry to the assembly station 8 is afforded by a pair of walls 54 and 55 positioned respectively above and below the wrapping line 3 , combining to function as the mouth 56 of a folding tunnel, and consequently as reaction means with which the group of packets 10 and the respective blank 12 are caused to interact after an element 2 of sheet material has been interposed between them.
  • the operation of folding the blank 12 around the packets 10 and the element 2 of sheet material is completed along the wrapping line 3 by conventional folder means not illustrated in the drawings.
