Definitions

  • the invention relates to a method for checking cardboard packs with regard to the correct formation of (bottom and / or top) walls formed from folding tabs and fixed by adhesive and / or adhesive strips. Furthermore, the invention relates to a device for performing the method.
  • the cardboard packs mentioned here are primarily large-volume packs made of corrugated cardboard or the like. They are mainly used to hold smaller packs. For example, small containers of cigarette packs - so-called cigarette sticks with e.g. ten or twenty cigarette packs - packed in such cardboard packs.
  • Cuts for the production of carton packs are common Ch folded first so that a rectangular or square "tube” surrounding the package is formed, which is open on two opposite sides. These open sides are then closed by partially overlapping folding tabs, namely two opposite and complementary inner tabs and two mutually opposite and complementary outer tabs.
  • the folding flaps create the bottom wall and top wall.
  • the folding tabs are connected to each other by gluing.
  • glue surfaces are applied to the inner lobes and / or to the inside of the outer lobes.
  • the carton pack can be closed by an adhesive strip applied on the outside.
  • the invention is concerned with the testing of the closure of such or similar carton packs.
  • the object on which the invention is based is to reliably determine any errors in the area of the closure, namely in the area of the walls formed from the folding tabs.
  • the method according to the invention is characterized in that, immediately after completion of the walls, pressure is exerted on them in the region of adjacent cardboard edges by folding the folding tabs in such a way that the folding tabs are moved out of the wall plane by incorrectly formed walls.
  • the pressure treatment according to the invention of the folding tabs glued or connected to one another ensures that faulty carton packs are also identified in which the connection of the Folding flap to the outside is apparently correct.
  • the pressure load in the plane of the walls formed by the folding tabs ensures that inadequate (adhesive) connections lead to the opening of the folding tabs and thus to the incorrect packing being determined.
  • the device according to the invention for testing cardboard packs is equipped, following a gluing and folding station, with a test station in which the cardboard packs are acted upon by pressure members which generate pressure in the plane of the walls formed by the folding tabs. Cardboard packs with intact walls withstand the pressure.
  • any incorrect packs are identified in the area of a test station and sorted out in terms of conveyor technology.
  • light barriers extend in a plane parallel to the walls formed from folding tabs, in particular in a vertical plane. In this way, folding tabs that protrude to the side or adhesive strips - if the adhesive strips are incorrectly attached - are recognized.
  • the adhesive strip is expediently applied by a corresponding application element following the test station, but in the conveying direction in front of the control station tion. In the area of the control station, possibly incorrectly applied or insufficiently adhesive adhesive strips are identified.
  • the embodiment shown in the drawings is concerned with the production of cardboard packs 10 for holding, for example, cigarette sticks.
  • the Carton packs 10 are transported on a feed conveyor 11 (in cycles).
  • the feed conveyor 11 here consists of two spaced apart support rods 12, 13, on which the carton pack 10 rests and is slid on.
  • the transport is carried out by drivers 14 of a (chain) conveyor acting on the rear.
  • the carton pack 10 consists of a blank, e.g. made of corrugated cardboard that surrounds the contents of the pack.
  • the carton pack 10 is initially open on both sides - upright side surfaces parallel to the conveying direction.
  • the blank has folding flaps which can be folded onto one another, namely inner flaps 15, 16 and outer flaps 17, 18.
  • the aforementioned folding flaps 15. 18 are folded over one another to form, for example, bottom wall 19 and top wall 20.
  • the inner tabs 15, 16 proceed from mutually opposite vertical edges 21, 22, while the outer tabs 17, 18 merge into upper walls of the cardboard pack 10 via upper and lower horizontal edges 23, 24.
  • the outer tabs 17, 18 in the present example of a carton pack 10 are dimensioned such that they completely cover the bottom wall 19 or the top wall 20 and abut one another in the region of a parting line 25. This is arranged in the middle.
  • the carton packs 10 are filled outside the aggregates shown here and partially folded in the area of the bottom wall 19 and the top wall 20, namely with respect to the inner tabs 15, 16. These are already folded into the end position when the carton Pack 10 reaches the area of a gluing station 26.
  • the outer tabs 17, 18 are pre-folded here so that they are in an inclined position (Fig. 5). With this relative position of the outer tabs 17, 18, the carton pack 10 can glue members 27, 28 arranged on both sides of the feed conveyor 11 are moved past such that appropriately designed nozzle heads 29 extend adjacent to the inside of the oblique outer tabs 17, 18 (FIG. 5). In this position, glue strips 30, 31 (hot-melt) can be sprayed onto the inner tabs 15, 16 in two successive spray cycles.
  • a folding station 32 follows the gluing station 26 in the conveying direction. Two measures are carried out in this in the area of the folding tabs. Firstly, the outer tabs 17, 18 are pressed against the inner tabs 15, 16, that is to say folded in the end position. On the other hand, the outer tabs 17, 18 are corrected or aligned with respect to the relative position after this folding step in such a way that the outer tabs 17, 18 abut each other in the region of the parting line 25.
  • folding elements are arranged laterally next to the feed conveyor, which can be moved in the transverse direction against the carton pack 10.
  • these are roller folders 33, 34 on both sides of the feed path 11.
  • Each roller folder 33, 34 consists of a U-shaped support frame 35 with horizontally directed flanges 36. Inside the support frame 35, namely between the upper and lower Flanges 36, a larger number of freely rotatable pressure rollers 37 is arranged with an upright axis of rotation.
  • the roller folders 33, 34 formed in this way are moved from a retracted position (FIG. 5) to a folded position (FIG. 6, left), bearing against the outer tabs 17, 18 pressed against the inner tabs 15, 16.
  • the roller folder 33, 34 can remain in this folding or pressing position if the carton pack 10 is conveyed further out of the folding station 32 after the measures provided have been carried out.
  • the pressure rollers 42 can be moved against the load of a compression spring 45 or dodge.
  • the pressure rollers 42 of a counter-holder 43 are arranged on an elongated carrier 46 which is pivotably mounted on a crossbar 47 which extends above the movement path of the carton packs 10.
  • the carrier 46 is provided with a shoulder 48 which is attached to the crossbar 47 with a joint 49.
  • the compression springs 45 are supported with the upper end also from the appropriately dimensioned crossbar 47.
  • the fully folded cardboard packs 10 arrive in the area of a tape station 50 by further transport on the feed conveyor 11.
  • an adhesive strip 51 is applied to the side surfaces, that is to say to the bottom wall 19 and / or top wall 20.
  • the adhesive strip 51 is attached so that the parting line 25 between the two outer tabs 17, 18 is covered.
  • the adhesive strip 51 is applied by means of tape units 52, 53 of conventional design arranged on both sides of the feed conveyor track.
  • a tape 55 provided with an adhesive is pulled off a bobbin 54, transferred to the cardboard pack 10, pressed against it and cut to a suitable length.
  • the cardboard pack 10 completed by attaching the adhesive strip 51 arrives at a control station 56 on the feed conveyor 11.
  • the cardboard pack 10 is checked for correct formation in the region of the bottom wall 19 and the top wall 20.
  • the cardboard pack 10 is raised, namely by (three) pressure strips 57, 58, 59, which grip the latter in the region of the lower horizontal edges 23, 24 and in the middle of the cardboard pack 10.
  • the pressure bars 57, 58, 59 are connected via upright webs 60 to a transverse support beam 61 which can be moved up and down by lifting rods 62.
  • the carton pack 10 is located (in the control station 56) on a cross conveyor 63, in the area of which the control station 56 is formed following the feed conveyor 11.
  • the cross conveyor 63 is designed as a roller conveyor with two conveyor sections 64 and 65. Correctly designed carton packs 10 leave the control station 56 via the conveyor section 64, that is to the left in FIG. 1. Incorrect packs are separated out via the conveyor section 65 to the right.
  • drive rollers 66 of the two conveying sections 64, 65 can be rotated in both directions by a common drive.
  • the drive rollers 66 each equipped with gear wheels 67, are connected to one another by a common chain drive 68.
  • each of the drive rollers 66 is provided with a sprocket 69 for a common drive chain 70 which includes all drive rollers 66.
  • a common drive 71 which has a reversible drive motor 72, is installed on the machine frame below the plane of the drive rollers 66.
  • the drive motor 71 connected to one of the drive rollers 66 causes the drive rollers to rotate in one direction or the other, depending on whether an intact carton pack 10 is to the left on the conveying section 64 or a defective carton pack 10 is to the right on the conveying section 65 in a processing tion station 73 is to be promoted.
  • the control station 56 is formed in the area of the cross conveyor 63 following the feed conveyor 11. To carry out the test, the carton packs 10 are lifted in the control station 56 by the pressure bars 57, 58, 59 from the drive rollers 66 of the cross conveyor 63 and brought to bear against elastic pressure members arranged above the carton pack 10. These are also arranged in the region of the (upper) horizontal edges 23.
  • the relatively narrow pressure bars 57..59 are each arranged between adjacent drive rollers 66 and can be lowered below the level of the cross conveyor 63.
  • the lifting rod 62 can be actuated by a lifting gear 74, which essentially consists of a crank mechanism 75.
  • the middle pressure bar 58 serves as an additional support member for the carton pack 10.
  • the counterpressure member which is mounted in a stationary manner above the carton packs 10, here consists of two lateral pressure beams 76, 77. These are supported on a part of the machine frame by means of support rods with compression springs 79, namely on a support plate 80 Pressure bar 76, 77 raised while increasing the contact pressure. As a result, pressure is exerted on the sideward walls (bottom wall 19, top wall 20) formed from the folding tabs, which leads to the opening of improperly bonded folding tabs.
  • Cardboard packs 10 which are formed incorrectly are identified in the control station 56 by optoelectric sensors.
  • photo sensors namely a transmitter 81
  • the vertical light barrier formed between them is formed closely, namely with a small distance, next to the sideways-facing walls (bottom wall 19, top wall 20) of the carton pack 10. Any protruding parts of these walls, in particular folding tabs and / or adhesive strips 51, are found. They lead to a sorting out of the relevant carton pack 10 into the processing station 73 by correspondingly driving the drive rollers 66.
  • the defective carton pack 10 rests on freely rotatable, but not driven, support rollers 83.
  • the defect in the carton pack 10 is eliminated manually here.
  • the corrected carton pack 10 is then returned in the conveying flow, namely in the event of a gap in the supply of correct carton packs 10 with a corresponding drive direction of the drive rollers 66.
  • the exact time of introduction of the repaired carton pack 10 into the conveying flow is determined by a stop 84 which holds the carton pack 10 resting on the drive rollers 66 in the raised position until the path for the carton pack 10 is clear is. the stop 84 is lowered by a pivot lever 85 so that the carton pack 10 can then be removed automatically.
