Definitions

  • the invention relates to a device for producing packs from at least one foldable blank, in particular cigarette soft-cup packs, in which individual blanks in a transfer station can be fed by a feed unit to a folding turret with receptacles (hollow mandrels) for each blank, the blanks be held ready by a stationary blank holder for takeover by one of the receptacles (hollow mandrel).
  • High-performance packaging machines are required for the manufacture (folding) and filling of cigarette packs. Particularly high demands are placed on machines for the production of soft cigarette packs.
  • This type of pack has an inner wrapping on, in particular a tinfoil cut, which surrounds the cigarette group on all sides as a pack content.
  • the tinfoil block thus formed is accommodated in a cup made from a paper blank that is open on the top or front side.
  • Packaging machines for the production of this type of packaging are predominantly equipped with a folding turret which has a plurality of receptacles arranged along the circumference in the form of hollow mandrels. These are elongated receptacles with a rectangular cross-section for internal (tinfoil) cutting and subsequently paper cutting. The blanks are wrapped around the stationary hollow mandrel and then - together with the cigarette group previously introduced into the hollow mandrel - are pulled longitudinally from the hollow mandrel.
  • the previously known packaging machines for soft cup packs and similar types of packs have a limited performance primarily because the complex folding turret is driven in cycles.
  • a continuously revolving folding turret is shown in DE-A-20 32 184.
  • the blanks are fed in tangentially to the outer circumference of the receptacles formed there as winding mandrels.
  • a feed drum holding the blank is provided radially outside the receptacles.
  • the cut is brought to the winding mandrel with one edge and held there with additional levers.
  • the overall structure is complex and the achievable performance is limited.
  • the object of the invention is to improve the performance of a packaging machine of the type mentioned at the outset, without at the same time accepting losses in terms of the quality of the packaging or with regard to the treatment of the contents of the pack (cigarette groups).
  • Dispensing with the standstill phases of the folding turret first requires a manner of feeding the blanks, namely the tinfoil blank on the one hand and the paper blank on the other hand, to the respective hollow mandrels on the folding turret.
  • the blanks are fed into the (circular) movement path of the hollow mandrels arranged at intervals from one another on the folding turret, namely by a blank holder which is arranged stationary next to the moving path of the hollow mandrels and which holds the blank in the position for acceptance by one of the continuously rotating hollow mandrels brings.
  • the blank holder is designed as a circular, rotationally driven holding disk with suction bores on the peripheral surface.
  • the cyclically driven holding disk which is stationary during the takeover of a blank by a hollow mandrel, detects a blank only in the area of an edge strip.
  • the blank is held in the transfer position so that the circumferential hollow mandrel grips the blank from the rear and takes it away from the holding disc when it is removed. It is important that the blank on the holding disc has a three-dimensional shape, namely that of a partial cylinder. As a result, the blank, which is made of thin material, is kept ready for wrinkling by the hollow mandrel.
  • the blank holder (holding disc) and this upstream blank conveyor are designed so that the blanks can be fed and brought into position at high speed according to the performance. For this, the cut after the Detachment from a material web accelerates.
  • the blank is held on the blank conveyors by suction air, which is controlled in such a way that the conveyance of the blank as well as the transfer from one blank conveyor to the next run exactly at high speed.
  • the continuously revolving folding turret is designed so that the pack (soft cup pack) can be completed during one revolution of the folding turret - except for the front fold of the tinfoil cut - and the contents of the pack (cigarette group) can be pushed off the hollow mandrel.
  • the folding turret is equipped with a plurality of movable pressing members which are assigned to each hollow mandrel and which fix the blank to a hollow mandrel during the takeover of the blank and during folding thereof at different locations.
  • the pressing elements in question are assigned, on the one hand, narrow side surfaces which extend in the circumferential direction at the front and rear, and an inner surface of the hollow mandrel corresponding to the front of the pack.
  • the relevant pressing members are designed to be movable back and forth in the radial direction or are pivotably mounted. The control takes place via cams, cams etc.
  • the folding turret is assigned a number of stationary folding members which carry out folding of the blanks on the radially outer side (outer surface) and on a free end face of the hollow mandrel during the conveying movement of the folding turret.
  • these are initially folding members that cover the radially outer hose fold (hose cover) of the blank.
  • folding elements are used that fold the bottom of the tinfoil cut in the area of the free end face (envelope folding).
  • organs for fixing and stabilizing folds are assigned to the folding turret following folding organs.
  • the cigarette groups are fed along a partial circumference of the folding turret to the hollow mandrels, namely pushed into and through them in the longitudinal direction thereof, the cigarette groups taking along the largely finished folded blanks (cups Pack) emerge from the hollow mandrels.
  • the cigarette groups are preferably made by an endless pocket chain, at least in the area of the folding turret, continuously and at the same speed as this, particularly in the version according to DE-A-35 27 741.6.
  • the pocket chain rests against the pocket in such a way that pockets of the pocket chain are aligned with the hollow mandrels, so that by sliding elements movable in the longitudinal direction of the hollow mandrels, the cigarette groups are pushed out of the pockets, pushed into the hollow mandrels and pushed through them can be.
  • the part of a complete packaging machine that is of interest here essentially consists of a folding turret 20 with assigned aggregates.
  • the folding turret 20 is driven continuously in a rotating manner.
  • Soft cup packs for holding cigarette groups are produced and filled during one revolution.

  • the protrusions are each folding tabs 26, which are folded against the free, open end of the hollow mandrel 23 to form a bottom wall of the tin foil blank 21 or the paper blank 22.
  • the hollow mandrels 23 are attached to the turret disk 24 in such a way that narrow side faces, namely a front side face 27 and a rear side face 28 are turned forward or backward in the circumferential direction. These are assigned to the narrow side walls of the pack.
  • a larger inner surface 29 and a corresponding outer surface 30 are directed radially inwards and outwards. The former is used to place front walls of the blanks or the pack, while 30 rear walls rest on the outer surface.
  • the folding turret 20 is assigned cutting units 31 and 32 for the production of the tinfoil blanks 21 or the paper blanks 22 and for transferring them to the hollow mandrels 23 of the folding turret 20.
  • the blanks are made from a continuous tinfoil web 33 or a paper web 34 separated.
  • the cutting units 31 and 32 are each arranged in a stationary manner on the circumference of the folding turret 20 in the region of a first transfer station 35 and a second transfer station 36 for the cuts 21, 22.
  • the necessary folds are carried out on the tinfoil blank 21, namely a hose overlap 37 on the outer surface 30 of the hollow mandrel 23 and a bottom wall 38 trapezoidal folding of the folding tabs 26.
  • the paper blank 22 is then applied to the hollow mandrel 23 or to the already folded tinfoil blank 21 on the hollow mandrel.
  • the paper blank 22 is then folded, likewise with the formation of a hose overlap 39, but in the region of the rear side surface 28 in the conveying direction. Furthermore, the folding tabs 26 protrude beyond the rotary range of the folding turret 20 and are stationary folded over to form a bottom wall 40.
  • the first transfer station 35 is located laterally on the folding turret 20 rotating in an upright plane, approximately in the horizontal central plane.
  • the transfer station 36 is formed offset by a quarter circle approximately in the vertical central plane. Opposite this, namely in the area of a lower pitch circle, occurs a pocket chain 41 to the circumference of the folding turret 20. This is formed with individual pockets 42, in each of which a cigarette group (content of a pack) is accommodated.
  • the pocket chain 41 which is driven continuously or synchronously in the area of the folding turret 20, is received by the folding turret 20 such that a number of pockets 42 are aligned with associated hollow mandrels 23 during the synchronous movement, so that the cigarette groups are transferred to the hollow mandrels 23 and finally to the blanks 21, 22 folded over one another.
  • the tinfoil web 33 is fed to a knife roller 44 at a defined speed via a pair of pull rollers 43.

  • a single row of suction bores 49 is provided, which exerts a lower holding force.
  • the suction bores 47, 49 or the suction channel 48 connecting them to one another is connected in the usual way to a stationary suction segment 50. Suction air is transmitted to the suction bores as long as the suction channel 48 is in the area of the suction segment 50 is located.
  • the tinfoil web 33 is transferred to a further blank conveyor, namely to an acceleration roller 51, which is also provided with systematically distributed suction bores along the circumference.
  • Two rows of suction bores 53 are assigned to one (axially parallel) suction channel 52 for grasping the respective front part of the tinfoil sheet 33.
  • This is followed by a number of individual rows of suction bores 54 arranged at equal distances from one another, each with suction channel 55.

These are arranged concentrically with the control disk 56 or the acceleration roller 51. When the ends or mouths of the suction channels 52, 55 are covered with the suction segments 57, 59, suction air is applied to the suction bores 53, 55 via a central vacuum line (not shown).
  • the (main) suction segment 57 is arranged along the conveying path from the area where the tinfoil web 33 is taken over by the knife roller 44, almost up to an intermediate conveyor roller 60 which takes over the tinfoil blank 21 from the acceleration roller 51.

  • the suction segment 57 has a smaller axial depth in this area (marking by dotted area) than in the previous area. For example, while the suction segment 57 has a depth (in the axial direction) of 6 mm in the region of the increased suction force, the region facing the intermediate conveyor roller 60 has a depth of only 1 mm.
  • a short venting segment 64 is formed concentrically or on the circular path of the suction segment 57 in the control disk 56 in order to reliably remove the tinfoil blank 21 by reducing the negative pressure to the suction bores To pass 65 equipped intermediate conveyor roller 60.
  • the suction bores 65 of the intermediate conveyor roller 60 are distributed over a larger circumferential area and connected in rows to axially parallel suction channels 66.

  • Each push rod 124 is slidably mounted in the longitudinal direction in an axially parallel bore of the guide 123.
  • each push rod 124 is provided with a lateral guide roller 145, which runs in a guide groove 126 of a control body 127 of the folding turret 20.
  • the guide groove 126 is designed so that the push rod 124 can perform a long stroke by rotating the turret disk or the support member 119 as a result of the movement of the guide roller 125 in the guide groove 126.
  • the control body 127 is fixed.
  • the turret shaft 118 passing through the control body 127 is rotatably mounted in the latter, so the control body 127 is supported on the turret shaft 118.
  • control body 127 Adjacent to the turret disk 24, the control body 127 forms a (fixed) control wall 128. This is provided with a plurality of control grooves 129, 130 and 131 running all around on the side facing the turret disk 24 for carrying out controlled movements of the aforementioned organs of the folding turret 20.
  • the rear part of the control body 127 which is remote from the control wall 128, is cylindrical and is covered on the outside by the support part 119 provided with a cylindrical projection 132.
  • Each push rod 124 is retractable into an outermost position in which a push rod end plate 133 or push rod 124 lies outside of the recess 120 or the path of movement of the pocket chain 41.
  • the plunger is then moved through the pocket 42 of the pocket chain 41 in the lower region, taking the cigarette group in the pocket 42 with it.
  • the cigarette group passes through the passage opening 25 of the turret disk 24 directly adjacent to the pocket chain 41 into the hollow mandrel 23 a.
  • the folded blanks 21 and 22 are now pulled off or pushed off the hollow mandrel 23 while simultaneously taking up the cigarette group.
  • the upper end wall of the tinfoil blank 21 must now be produced.
  • the push rod 124 is then pulled back into the starting position so that the pocket chain 41 can run from the circumference of the folding turret 20. Thereafter, however, the push rod 21 is moved back into the push end position in which the push rod end plate 133 is approximately flush with the free end of the hollow mandrel.
  • the plunger end plate 133 now forms a bottom against which the folding tabs of the bottom walls 38 and 40 can be folded.
  • the organs described above for holding and folding the blanks 21 and 22 on the hollow mandrels are designed in a special way and are movably mounted on the turret disk 124.
  • Each hollow mandrel 23 is assigned a radially movable supporting plunger 134, which is slidably mounted on the turret disk 24 in two sliding guides 135.
  • a guide roller 137 is attached to a cross arm 136 and enters the control groove 131 of the control wall 128 already mentioned.
  • the shape of the control groove 131 is shown in FIG. 1 and in FIG. 10 by dash-dotted lines.
  • the folding leg 98 is attached and on the other hand the pressure plate 95.
  • the latter is elastically supported on a transversely projecting bracket 138 at the end of the support plunger 134.
  • the pressure plate 95 is mounted on two spaced-apart holding plungers 139 which are slidably mounted in the bracket 138.
  • the holding plungers 139 are surrounded by support springs 140 which are supported on the one hand on the underside of the pressure plate 95 and on the other hand on the bracket 138.
  • the pressure plate 195 is thus brought to the hollow mandrel 23 or the blank 21, 22 with increasing contact pressure. At the same time it is ensured that first the blank 21, 22 is gripped by the pressure plate 95 and then the folding leg 98 comes into effect when the pressure force increases.
  • the two pressers 94 and 106 which are each mounted between adjacent hollow mandrels 23, are actuated by swivel arms 141 and 142, at the ends of which they are arranged as laterally projecting, namely projecting parts.
  • the swivel arms 141, 142 can be moved in different lengths and in different planes so that they can be guided past one another (FIG. 9).
  • actuating pins 143, 144 are rotatable in the turret disk 24 mounted actuating pins 143, 144 attached. These are each connected to a crank mechanism 145, 146. These are actuated by guide rollers 147, 148 in the control grooves 129 and 130 already mentioned. By appropriately designing the control grooves 129, 130 (dash-dotted line in FIG. 1), pivoting movements are transmitted to the pivoting arms 141 and 142.
  • the presser 94 for fixing a blank 21, 22 to the front side surface 27 of a hollow mandrel 23 is designed with a large pressing surface, namely as a U-profile.
  • the presser 106 is designed as a simple rod that can enter the open cavity of the U-profile in certain areas, namely in particular in the area of the transfer stations 35 and 36, so that both pressers 94 and 106 can be folded together in the smallest space, in each case on a rear side surface 28 of the hollow mandrel, so that as large a space as possible to the adjacent hollow mandrel is released for the passage of the blank 21, 22 supplied by the holding disk 68.
