Definitions

  • the object of the invention is a wrapper apparatus for wrapping packs substantially having the shape of a rectangu­lar parallelepiped, particularly cigarette packs, or the like, to be wrapped each into a wrapper made of an even soft sheet material, i.e., with a low stiffness and/or being easily chargeable with statical electricity, such as poly­ethylene or the like, which apparatus consists of a spider rotor comprising a plurality of angularly equispaced, out­wardly open radial pockets that by the spider rotor being indexed, are moved the one after the other into a pocket feeding station, in which through the radially outward pock­et opening a pack to be wrapped is inserted into each pock­et, along with the respective wrapper, which as a pack P is being inserted into the respective pocket, is folded in the form of a U around its pack, with both of its radially ex­tending flaps formed by the free end portions of the U fold, remaining out of, and projecting from
  • the radially out­ward side of a pack to be wrapped slightly projects from the radi­ally outward opening of this pocket, i.e., from the free edges of both walls which delimit the pocket at its trailing and leading side, as considered with respect to the direc­tion in which the spider rotor is indexed, and which are preferably formed by two or more arms set in an equispaced relation.
  • Patent GB-A-2 003 817 is known to have both ends of the first folded, radially ex­ tending trailing wrapper flap held by flap-retaining vacuum means against the matching sides of the respective pocket.
  • this device the use of a vacuumn generator and the provision of suitable suction ducts in the several pock­ets in the rotor spider are required, which results in the construction of the apparatus being rather complicated and expensive.
  • the radially extending trailing wrapper flap which is first folded over against the radially outward side of a pack, and is held by suction at both of its ends, tends to become cambered because of its stiffness, so that it may hamper the folding of the radially extending leading flap.
  • the invention seeks to eliminate the said drawbacks of the known prior art embodiments, and aims to provide an ap­paratus of the type as decribed at the outset, in which the radially extending trailing wrapper flap that is first fold­ed over against the respective radially outward side of a pack, is effectively and simply prevented from being drawn away therefrom, so that the said flap will be held in a quite flat and outstretched condition.
  • each pocket is fitted at the trailing edge (as considered with respect to the direction in which the spider rotor is indexed) of its radially outward opening, with one or more flap retaining teeth slightly protruding beyond the radially outward side of a pack fully inserted into the res­pective pocket, and both the reciprocatingly operated folder for folding the radially extending trailing wrapper flap, and the successive stationary folder for subsequently fold­ing the radially extending leading wrapper flap, are formed with a slot and/or groove which is in-line with each of the said flap retaining teeth, whereby the said folders are allowed to respectively graze the radially outward side of the pack.
  • the radially extending trailing wrapper flap can be folded over so as to be caused to well bear against the radially outward side of a pack inserted into the respective pocket, since the slot or slots, or grooves, formed in the reciprocatingly operated folder set in an aligned relation with the flap retaining tooth or teeth, on the trailing side of the pocket opening, permit the said reciprocatingly operated folder to be drawn quite close to the said radially outward side of this pack, and to graze the same, notwithstanding the provision of the said tooth or teeth.
  • the flap retain­ing tooth or teeth according to the invention effectively prevent the folded over trailing flap to be drawn away dur­ing the back stroke of the reciprocatingly operated folder and/or while the spider rotor is being indexed by one step.
  • Any undesired cambering of the folded over trailing wrapper flap is also avoided, in that such a drawing away of the same is prevented not by fastening or firmly holding both ends of the folded over trailing wrapper flap, but by means of one or more abutment members formed by the said flap re­taining tooth or teeth, which are caused to cooperate with the radially outward pack edge over which the said wrapper flap is folded, so that the folded over trailing wrapper flap is left entirely free, and is thus allowed to take a flat and outstretched position.
  • the radially extending leading wrapper flap is by the stationary folder folded over the already folded, radially extending trailing wrapper flap, so as to be caused to perfectly bear against the radially outward side of the respective pack, in that the flap retaining tooth or teeth become engaged in the respective slot or groove in the stationary folder.
  • the flap retaining tooth or teeth according to the in­vention may be used also in wrapper apparatus of the kind as described at the outset, in which the two overlapped radial­ly extending wrapper flaps that are folded over the radially outward side of a pack, are welded together by one or more welding devices arranged at the periphery of the spider ro­tor, in one or more positions downstream of the pocket feed­ing station (as considered with respect to the direction in which the spider rotor is indexed), and which must bear ag­ainst the said radially outward side of each pack inserted into the respective pocket in the spider rotor.
  • each pocket in the spider rotor has its radially inward end side delimited by a pack bearing bottom which at the pocket feeding station, and preferably also at the initial end of the successive sta­tionary folder, is located in such a radial position that the flap retaining tooth or teeth provided on the trailing edge of each pocket opening, will protrude beyond the radi­ally outward side of a pack; the said pack bearing bottom is then caused to take in the direction in which the spider ro­tor is indexed, such a radial position at the welding device or devices that each pack accomodated in the respective pocket, is pushed radially outward, up to have its radially outward side projecting beyond the said flap retaining teeth.
  • the welding device or devices are allowed to extend
  • the said pack bearing bottom may consist of a stationary part for supporting on its surface the radially inward end sides of the packs and for causing the same to slide thereon, the said part extending over a certain angle around the axis around which the spider rotor is indexed, from the pocket feeding station to the welding device or devices, with its radial distance from the axis around which the spider rotor is indexed, being at the same time continuously and gradual­ly increased in the manner of a cam, while a constant radial distance from the axis around which the spider rotor is in­dexed, is preferably maintained at the welding device or de­vices.
  • the invention also comprises an embodiment in which the said pack bearing bottom is formed by a plurality of radial­ly movable bottom members which are each associated with a pocket in the spider rotor, and which are displaceable by any suitable means fit for this purpose, such as radially arranged cam followers and a fixed cam, provided about the axis around which the spider rotor is indexed.
  • the apparatus according to the invention shown in Fig.ure 1, comprises a spider rotor generally designated by nu­meral 1, which consists of a rotary drum 2 fitted on shaft 3, and the said drum 2 is provided with a plurality of angu­larly equispaced radial pockets 4 for cigarette packs P to be accomodated thereinto.
  • Each radial pocket 4 consists of two pairs of radially extending, spaced apart arms 104, 104′ forming the leading and the trailing side of the respective radial pocket 4, as considered with respect to the direction in which the spider rotor 1 is indexed, indicated by arrow R, each arm pair 104, 104′ being provided at one of the ax­ially extending side ends of the respective pocket 4.
  • the end sides of the radial pockets 4 are each delimited by a pair of folders 5.
  • a cigarette pack P is inserted into a ra­dial pocket 4 formed by the two pairs of radially extending arms 104 and 104′, with its narrow longitudinal side turned toward the axis of drum 2, so that the distance between each radially extending leading arm 104 and the associated radi­ally extending trailing arm 104′ (as considered with respect to the direction in which the spider rotor 1 is indexed) substantially corresponds to the thickness of pack P, and the two pairs of radially extending arms 104, 104′ of each radial pocket 4 are so spaced apart from each other that the end sides of an associated cigarette pack P are received therein.
  • each radially extending trailing arm 104′ (as considered with respect to the direction in which the spider rotor 1 is indexed) is fitted at its free radially outward edge with a flap retaining tooth 204′.
  • This flap re­taining tooth 204′ is preferably so provided on the axially inward side of the said radially extending trailing arm 104′ as to be as near as possible to the transversal median plane of drum 2.
  • the wrappers F to be wrapped around packs P are cut from a continuous sheet material web N being unwound from a bobbin (non shown) by a known cutting device arranged over the pocket feeding station A, with the roller 8 forming part of the said cutting device (see Figure 2).
  • the wrappers F are each placed between that pocket 4 in the spider rotor 1 which comes to be locat­ed in station A and the respective cigarette pack P to be inserted into this pocket 4, so that as the pack P associat­ed with this radial pocket 4 is being inserted thereinto, a wrapper F is folded in the form of a U around the said pack P, with both of its flaps formed by the free end portions of the U fold, remaining out of, and projecting from the op­ening of pocket 4, which is delimited by the free edges of the radially extending arms 104, 104′. (On pack P being in­serted into pocket 4, the first folds in wrapper F are form­ed by the pair of folders 5 against the end sides of pack P).
  • the wrapper apparatus is fitted with a reciprocatingly operated folding blade 9 for folding over the projecting trailing flap of wrapper F (as considered with respect to the direction in which the spider rotor 1 is indexed) closely against the ra­dially outward side of pack P.
  • the free edge of the trailing flap-folding blade 9 so extends as to be substantially flush with the radially outward side of pack P.
  • the said trailing flap-folding blade 9 is formed with two slots 109 which are respectively in line with each flap retaining tooth 204′ on the radially extending trailing arms 104′ (as considered with respect to the direction in which the spider rotor 1 is indexed), whereby the said trailing flap-folding blade 9 is allowed to graze the relative radially outward side of pack P.
  • the said covering member 10 is also formed with a groove 210 for each flap retaining tooth 204′ on the radially extending trailing arms 104′ (as considered with respect to the direction in which the spider rotor 1 is indexed), and extends over about one half of the periphery of the spider rotor 1, particularly from the pock­et feeding station A to a pack delivery station E.
  • two suc­cessive stations S1 and S2 are provided, in which the weld­ing is effected of a wrapper F leading and trailing flaps, which in the antecedent station A have been folded over ag­ainst the radially outward side of pack P.
  • a welding device designated as a whole by numeral 11 is provided in each one of these stations, with its welding head 111 being directed parallel to the radially outward side of a pack P that comes to be respectively positioned in these stations S1 and S2, and protruding through slots 310 formed in the covering mem­ber 10, into the said covering member 10.
  • two stationary parallel guides designated as a whole by numeral 12 which form the pack bearing bottom for the radi­ al pockets 4 coming to be located in this angular zone of the apparatus, are provided between the pairs of radially extending arms 104, 104′ forming the side ends of each radi­al pocket 4, for ensuring, notwithstanding the flap retain­ing teeth 204′, a welding with no solution of continuity of the wrapper F flaps having been folded over the one against the other, lengthwise of the radially outward side of pack P.
  • the stationary parallel guides 12 extend over a certain angle around the axis around which drum 2 is rotated, from the pocket feeding station A to the successive welding stations S1 and S2, with their ra­dial distance being continuously and gradually increased in the manner of a cam, from the axis around which drum 2 is rotated, while a constant distance of said guides from the said axis is preferably maintained at the welding stations S1 and S2.
  • a pack P accomodated in a pocket 4 that was initially located in the pocket feeding station A is caused to slide on the surface of guides 12, and is radially pushed in the outward direc­tion, in such a manner that in the welding stations S1 and S2 its radially outward side will slightly project beyond the flap retaining teeth 204′, and will continuously bear against the respective welding head 111, which therefore has not to be formed with grooves for the passage of the said flap retaining teeth 204′.
  • cigarette packs P generally are not shaped like a perfectly rectangular parallelepiped, but are made in form of a frustum of pyramid with rectangular parallel bases, and since the frusto-pyramidal packs are inserted transversely with respect to their height, into the radial pockets 4, the two pack bearing guides 12 are not adjustable independently of each other, so that they are each formed by two comb-like interengaged sections 112 and 212. This guarantees that the radially outward side of packs P be always directed parallel to the welding heads 111, and be flush with the reciprocat­ingly operated folding blade 9 and with the stationary, leading wrapper flap-folder 110, so that a perfect adherence of wrapper F against a cigarette pack P is ensured.
  • the wrapper apparatus according to the invention apart from being used for wrapping cigarette packs, may be used also for wrapping any other similar articles into wrappers.
