Definitions

  • the present invention relates to a packing machine.
  • Known continuous cigarette packing machines comprise a wrapping wheel powered to rotate continuously about a central axis and having a number of wrapping heads equally spaced about the central axis. As it rotates, the wheel feeds each head along a wrapping path through a supply station where the head receives a sheet of wrapping material and a respective product, about which the sheet of wrapping material is folded into a U so that two opposite wings project transversely from the product; through a first folding station where the sheet of wrapping material is folded to form about the product a tubular wrapping having two opposite open ends; and through a second folding station where the open ends are folded to complete the product wrapping.
  • Each wrapping head supports a respective folding device, which, as the wrapping head travels through the first folding station, folds a first of said two wings through 90° onto the product; and a second wing is later folded through 90° onto the product and partly onto the first wing by a further movable folding device located along the wrapping path at the first folding station.
  • each wrapping head oscillates, in use, in the neighborhood of a radial position with respect to the central axis of rotation of the wheel, so as to keep the head facing the supply station and/or a folding tool long enough to complete the relative operation.
  • Packing machines of the above type are relatively expensive, on account of the complex design of the wrapping heads, which, besides rotating about a radial position, must also support a movable folding device.
  • a packing machine for wrapping a product in a sheet of wrapping material, the machine comprising a wrapping head for housing said sheet of wrapping material and said product; a conveying head for feeding said product to said wrapping head at a supply station; and a supply unit for feeding said sheet of wrapping material to said wrapping head, in which the sheet of wrapping material is folded into a U about the product; characterized in that said conveying head comprises a movable folding device, and actuating means for activating the movable folding device to fold at least one portion of said sheet of wrapping material onto said product at said supply station.
  • Number 1 in Figure 1 indicates as a whole an automatic cigarette packing machine for producing packets (not shown) of cigarettes, and in which a group 2 of cigarettes is first wrapped in a sheet 3 of foil wrapping material and then inserted into a blank (not shown) which is folded about group 2 of cigarettes to form a packet (not shown) of cigarettes.
  • Packing machine 1 comprises a wrapping wheel 4 rotating continuously (clockwise in Figure 1) about a central axis 5 perpendicular to the Figure 1 plane, and having peripheral wrapping heads 6 equally spaced about axis 5 and which are fed along a closed, substantially circular wrapping path P1 as wheel 4 rotates about axis 5.
  • a seat 7 for first receiving and conveying a respective sheet 3 of wrapping material folded substantially into a U, and subsequently also a respective group 2 of cigarettes which is wrapped in sheet 3 of wrapping material.
  • Each group 2 of cigarettes is confined within a substantially parallelepiped space defined by a pair of parallel major lateral surfaces 8 and a pair of parallel minor lateral surfaces 9 perpendicular to surfaces 8.
  • Said space also comprises two opposite longitudinal ends 10, and a central portion 11 interposed between said two longitudinal ends 10.
  • a first portion P2 of path P1 extends through a supply station S1 having a known supply unit 12 (shown only partly) for supplying seat 7 of each head 6 with a respective sheet 3 of wrapping material, which is folded into a U inside seat 7.
  • Station S1 also comprises a further supply unit 13 located downstream from unit 12 in the traveling direction of wrapping heads 6 along path P1, and which provides for supplying seat 7 of each head 6 with a respective group 2 of cigarettes, which is inserted inside the respective U-folded sheet 3 of wrapping material, which, once group 2 is inserted, has two facing wings 14 and 15 projecting transversely from group 2.
  • First portion P2 of path P1 also extends through a folding station S2 where wings 14 and 15 of sheet 3 of wrapping material are folded through 90° onto group 2 and one onto the other to form a tubular wrapping 16 having two opposite open ends 17. More specifically, wing 14 is folded through 90° onto group 2 by a folding device 18 fed along a portion of path P1 extending through station S2, and wing 15 is folded through 90° onto group 2 and partly onto wing 14 by a folding device 19 located in a fixed position with respect to wheel 4.
  • wrapping path P1 extends through an unloading station S4 where wrappings 21 are extracted successively from respective seats 7 on wrapping wheel 4 and fed to known follow-up wrapping units (not shown) on machine 1.
  • Each wrapping head 6 is hinged to wheel 4 and is oscillated, with respect to wheel 4, about an axis 22 parallel to axis 5 by a known cam and rocker arm actuating device 23, of which respective wrapping head 6 defines the central portion of an end rocker arm 24 having an arm defined by respective seat 7.
  • Actuating device 23 provides for positioning head 6 substantially perpendicular to wrapping path P1 along first portion P2 of path P1. More specifically, actuating device 23 provides for oscillating each wrapping head 6 about respective axis 22 and in the neighborhood of a perpendicular position with respect to path P1 as head 6 is fed through stations S1 and S2, so as to cooperate with supply units 12 and 13 and with folding device 19.
  • Actuating device 23 also provides for setting head 6 in a fixed position substantially parallel to wrapping path P1 along second portion P3 of path P1, so that head 6 cooperates along path P1 with folding device 20.
  • Supply unit 12 comprises a transfer wheel (not shown) powered to rotate continuously about a fixed central axis (not shown) parallel to axis 5, and having peripheral, substantially trapezoidal folding spindles 25 (only one shown).
  • Each folding spindle 25 provides for withdrawing a respective sheet 3 of wrapping material from a known supply unit (not shown), and for feeding the sheet 3 of wrapping material, folded into a U, into a respective seat 7 at supply station S1.
  • respective spindle 25 and seat 7 act like a punch and die respectively, and provide for optimum U-folding of sheet 3 of wrapping material inside seat 7.
  • Seat 7 of each head 6 is defined by a bottom wall 26 fixed with respect to head 6, and by two lateral walls 27, which are hinged on opposite sides of wall 26 and oscillated, about respective axes parallel to axis 22, between an open position and a closed position by a known cam control device (not shown).
  • the two lateral walls 27 of each seat 7 form an obtuse angle with bottom wall 26, and seat 7 has a section in the form of an isosceles trapezium negatively reproducing the shape of folding spindles 25; and, in the closed position, the two lateral walls 27 of each seat 7 form a substantially right angle with bottom wall 26, and seat 7 has a rectangular section of substantially the same size as a group 2 of cigarettes so as to engage group 2 completely, i.e. by both central portion 11 and longitudinal ends 10.
  • the inner surfaces of walls 26 and 27 have a series of holes (not shown) connected to a known suction device (not shown) on wrapping wheel 4.
  • Supply unit 13 comprises a continuous conveyor 28 (shown partly) for feeding a number of seats 29 along a path P4 through a known loading station (not shown) where a group 2 of cigarettes is formed in or transferred to a respective seat 29 (in known manner not shown), and through supply station S1 where group 2 of cigarettes is transferred from seat 29 to a respective seat 7 by a further movable seat 30, which is carried by a transmission pulley 31 of conveyor 28 and provides for removing group 2 from seat 29 and feeding group 2 to seat 7.
  • Conveyor 28 comprises a known flexible toothed belt 32 (shown partly in Figure 1) which is fed along path P4 by pulley 31, which comprises a toothed central roller 33 rotating continuously (anticlockwise in Figure 1) about a central axis 34 parallel to axis 5, and two flanges 35 (only one shown in Figure 1) coaxial with axis 34.
  • Conveyor 28 also comprises a number of bodies 36 supported by and equally spaced along belt 32.
  • a respective seat 29 which has a longitudinal dimension (perpendicular to the Figure 1 plane) smaller than that of group 2, and a rectangular section of substantially the same transverse dimensions as a group 2 so as to engage group 2 by central portion 11, leaving respective longitudinal ends 10 substantially free.
  • Each body 36 is provided with a retaining device 37 comprising two jaws 38 integral with belt 32 and which oscillate between a gripping position along the straight portions of belt 32, and a release position along the curved portions (only one shown) of belt 32.
  • the two flanges 35 (only one shown in Figure 1) support, in between, a number of peripheral heads 39 (only one shown in Figure 1) equally spaced about axis 34 and mounted for rotation about respective axes 40 parallel to axis 34.
  • Each head 39 comprises two gripping devices 41 which together define a respective seat 30 for engaging a respective group 2 by respective ends 10.
  • Each gripping device 41 comprises two relatively thin L-shaped sections 42 lying in the same plane perpendicular to axis 40, and which are movable, with respect to each other and in said plane, between a release position and a gripping position (shown in Figure 1) in which sections 42 define a tubular seat 43 having an axis parallel to axis 34 and a rectangular section approximately equal to but no larger than the cross section of group 2.
  • Each head 39 is provided with a known cam and rocker arm control and actuating device (not shown) housed between the two flanges 35 and which, as pulley 31 rotates about axis 34, provides for controlling the angular position of seat 30 about axis 40 and between a loading position, in which seat 30 coincides with a respective seat 29 to withdraw a group 2 of cigarettes from seat 29, and an unloading position, in which seat 30 coincides with a respective seat 7 to transfer group 2 of cigarettes to seat 7.
