Definitions

  • the invention relates to a packaging device for producing blanks by separating them from a material web and feeding them to a packaging station by means of a blanking conveyor, which consists of peripheral, lateral, upright perforated belts with a conveying strand under vacuum through rear suction chambers for the linear transport of the blanks , and which is preceded by a suction drum, in the area of which the blanks can be separated from the material web.
  • a blanking conveyor which consists of peripheral, lateral, upright perforated belts with a conveying strand under vacuum through rear suction chambers for the linear transport of the blanks , and which is preceded by a suction drum, in the area of which the blanks can be separated from the material web.
  • DE-A 1 586 120 describes a first solution to this problem.
  • the material web is fed to a suction conveyor drum, that is to say a drum on whose outer lateral surface suction bores open.
  • a suction conveyor drum On this suction conveyor drum, blanks are separated from the material web by a rotating cutting knife.
  • the individual blanks are then detached from the suction conveyor drum by deflecting fingers and transferred to suction conveyor belts, which also fix the blank by suction.
  • the object (pack) can be moved between these suction conveyor belts, taking the cut that is slipped off the suction conveyor belts.
  • the disadvantage here is that the blank must be detached from the suction conveyor drum by deflecting fingers, ie it cannot be transferred directly from the suction conveyor drum to the suction conveyor belts.
  • suction fixation in the area of the transfer from the suction drum to the suction conveyor belts is interrupted, which considerably impairs the required guidance, so that there is a risk of disorderly conveying in this area.
  • blanks are removed from a blank magazine by a removal roller and fed to a gripper cylinder.
  • the blanks are gripped at a front edge in the conveying direction by pliers, transported along a pitch circle by rotating the gripper cylinder and then placed on suction belts of a conveyor.
  • the cuts are transferred to the suction belts in the area of a suction drum, which is also a deflection drum for the suction belts.
  • the suction belts can be supplied with suction air by the deflection drum.
  • GB-PS 967 491 deals with the transport of blanks in two staggered horizontal planes.
  • the blanks are transported by a belt conveyor designed as a suction belt, the blanks being fed in the region of a deflecting roller from an upper run to a lower run of the belt conveyor.
  • Upper run and lower run are provided with suction chambers which extend into the area of the deflection roller.
  • This device is not concerned with the context of the invention, namely that a blank is to be separated from a material web and to be transported tied up uninterruptedly until it is taken over by packs.
  • the object of the invention is to propose measures which ensure uninterrupted conveyance of the cut blanks until they are picked up by means of a pack or the like with a simple, reliable construction.
  • the suction drum is arranged in the region of an upper deflection roller for the perforated belts in such a way that the peripheral surface of the suction drum or the cut conveyed on it can be transferred directly to the peripheral surface of the deflecting roller of the perforated belts or to the latter itself.
  • two different conveyor systems namely a suction roller for performing the separating cut in the production of the blank on the one hand and perforated belts for conveying the blank to the packaging station on the other hand, are placed in such a spatial relationship that the blank separated on the suction drum starts immediately and without an intermediate conveyor which can be handed over to closely adjacent suction belts. This ensures an uninterrupted fixation of the blanks on the conveying elements acted upon by suction air.
  • the devices shown are part of a packaging machine, for example for the production of cigarette packs 10, and the cigarette packs 10 found predominantly on the market are provided with an outer wrapper, which in the present case consists of an inexpensive plastic film that is difficult to pack.
  • a blank 11 of the packaging material is kept ready in a plane transverse to the direction of transport of the cigarette pack 10 on a packing web 12, such that the blank 11 lies around the cigarette pack 10 in a U-shape as a result of the relative movement.
  • the cigarette pack provided in this way with a blank 11 is then fed into a folding turret 13, which carries out the further necessary folding of the blank 11 in a known manner.
  • the blanks 11 are separated one after the other from a continuously (or cyclically) supplied material web 14.
  • the conveyance of the same is effected by a pair of pull rollers 15, 16, which is mounted here above subsequent conveying members.
  • the material web 14 is transferred to an immediately adjacent, that is to say closely adjacent, axially parallel suction drum 17.
  • the blank 11 is separated from the subsequent material web 14 on the suction drum 17.
  • an approximately radially directed cutting knife 18 is inserted approximately radially into the suction drum 17 such that the outer cutting edge projects beyond the outer surface of the suction drum 17.
  • a rotating counter knife 19 With the help of a rotating counter knife 19, the cut is made at a predetermined, repeating interface, so that cuts of the same length are always cut off.
  • the above separating device can also be designed in a different way.
  • the circumferential suction drum 17 is equipped with radial suction bores 20, which open in several, preferably three suction rows 21 spaced apart from one another, on the lateral surface of the suction drum 17 and fix the material web 14 or the blank 11 when appropriately loaded with suction air.
  • the suction bores 20 of the three suction rows 21 are each connected to common, axially parallel suction channels 22 which lead to the axial end of the suction drum 17 and here temporarily connect to a suction groove 23 which is formed in a stationary distributor disk 24 mounted next to the suction drum 17 .
  • the suction groove 23 extends over the entire, approximately semicircular conveying area of the material web 14 or of the blank 11 on the suction drum 17.
  • a ventilation hole 25 separate from the suction groove 23 is expediently formed in the distributor disk 24 in the lower area. which facilitates the transfer of the blank 11 to a subsequent blank conveyor 26 as a result of venting the suction channels 22 and thus the suction bores 20 in this area.
  • This blank conveyor 26 transports the blank 11 in a straight line, namely in the vertical plane.
  • the blanking conveyor 26 rotates from two perforated belts 27 and 28 arranged at a distance from one another. These are guided over upper and lower deflection rollers 29 and 30.
  • the arrangement is such that the deflecting rollers 29 and 30 are arranged at approximately equal intervals on both sides, namely above and below, the packing web 12.
  • the perforated belts 27, 28 are acted upon by suction air in the region of a conveyor run 31, either through individual, elongated suction chambers 32 and 33 for each conveyor run 31 or through a common suction box 34 (FIGS. 6, 7 and 8).
  • the suction chambers 32, 33 are provided on the side facing the conveyor run 31 with openings or a continuous suction slot 35 which is covered by the conveyor run 31 of the perforated belts 27, 28.
  • the perforated belts 27, 28 are provided with suction holes 36, which enable the negative pressure through the suction chambers 32, 33 or the suction box 34 to take effect on the opposite side of the conveying strand 31, so that the blank 11 comes on during transport this is fixed.
  • the suction chambers 32 and 33 are formed in upright support elements 37, between which a recess 38 is formed for the passage of the cigarette pack 10. During this push-through movement, the blank 11 is pulled through the cigarette pack 10 from the conveyor runs 31 of the perforated belts 27, 28.
  • the perforated strips 27, 28 run in trough-like. Recesses 39 of the suction chambers 32, 33 and the suction box 34. The narrow depressions 39 are dimensioned such that the perforated strips 27, 28 running therein are approximately flush with the contact surface 40 facing the blank 11.
  • the suction holes 36 in the perforated bands 27, 28 and the suction slots 35 for the suction chambers 32, 33 are arranged offset inwards with respect to the longitudinal center planes of these parts.
  • the perforated belts 27, 28 are provided on the inner side facing the deflecting rollers 29 and 30 with transverse, rib-like elevations 41, through which perforated belts 27, 28 are formed like toothed belts.
  • At least the upper deflection roller 29 is equipped with corresponding recesses 42, into which the elevations 41 enter in a form-fitting manner. This ensures an exact, slip-free movement of the perforated belts 27, 28 with respect to the deflection rollers 29, 30.
  • the depressions 42 are formed in the region of recesses 43 of the deflecting rollers 29, 30. These recesses 43 or flat grooves are designed so that the perforated strips 27, 28 fit into this receptacle and are essentially flush with the lateral surface of at least the deflecting roller 29.
  • a suction hole 36 is arranged between each two elevations 41.
  • the present exemplary embodiments are designed in such a way that a continuous, uninterrupted fixation of the material web 14 and the product blank 11 is ensured by suction air at the conveying members involved, from the takeover of the material web 14 by the suction drum 17 to the delivery of the blank 11 to the cigarette pack.
  • the transfer of the blanks 11 formed on the suction drum 17 to the blank conveyor 26 is achieved in a special way.
  • the upper deflection roller 29 of the blank conveyor 26 is acted upon by suction air in the region of the lateral surface, at least in a circumferential region serving to convey the blank 11.
  • the suction air is fed to the blank 11 via the perforated belts 27, 28, so that the transport of the blank 11 in the region of the deflecting roller 29 already takes place decisively through the perforated belts 27, 28.
  • the deflection roller 29 consists of a hollow cylinder 44 which is rotatably mounted on a fixed support shaft 45. This also has the task of supplying the deflection roller 29 with vacuum.
  • the hollow cylinder 44 is equipped with radially directed suction bores 46 which each open in the area of the suction holes 36 of the perforated strips 27, 28 on the lateral surface of the hollow cylinder 44.
  • the suction bores 46 are connected to a vacuum system of the supporting axis 45, namely with a segment groove 47 which extends in the circumferential direction in the region of the suction bores 46. This is arranged and dimensioned such that the suction bore 46 is connected to the segment groove 47 during the transport area for the blank 11 are.
  • deflection roller 29, suction drum 17 and pull roller 16 are arranged one above the other in a common axis plane.
  • Suction drum 17 and deflection roller 29 are directly in operational engagement via gears 50, 51.
  • Another gear 52 drives the pull roller 16.
  • the suction drum 17 is supported on a continuous axis 53 at both ends.
  • the support axis 45 of the deflection roller 29 is supported on one side here.
  • the exemplary embodiment according to FIGS. 6 to 8 is in principle designed in the same way as that according to FIGS. 1 to 6.
  • the fixing of the blank 11 on the upper deflecting roller 29 with suction air takes place here in a different way.
  • the suction box 34 provided here is extended into the region of the deflecting roller 29, specifically by means of narrow suction segments 54, 55 which are designed in the shape of a circular arc and adjoin the suction box 34. These are here as relatively narrow, channel-like, namely, U-shaped air conveying elements in cross section.
  • the fixed suction segments 54, 55 extend in correspondingly designed and dimensioned circumferential grooves 56 and 57 of the deflecting roller 29. The dimensional differences are selected so that the deflecting roller 29 is freely rotatable relative to the suction segments 54, 55, the radially outer side of the suction segments 54 , 55 is open, thus forming a suction slot 58.
  • the suction elements 54 extend below the perforated strips 27, 28, namely in the area of the suction holes 36 thereof. Accordingly, analogously to the exemplary embodiment according to FIGS. 1 to 5, the perforated belts 27, 28 are also acted upon by suction air in the region of the deflecting roller 29, so that they can already fulfill their promoting and fixing function with respect to the cut here.
  • the blank is fixed and conveyed in the region of the deflecting roller 29.
  • the suction elements 55 are offset laterally, namely inwards, relative to the perforated bands 27, 28.
  • the suction segments 55 are essentially flush with the lateral surface of the deflecting roller 29, so that the suction slots 58 can act directly on the blank 11 here.
  • the conveying members 16, 17, 29 are here in the same or similar relative position to one another as in the previously explained exemplary embodiment.
  • the suction box 34 is designed analogously to the suction chambers 32, 33 with respect to the guidance of the perforated strips 27, 28.
