Definitions

  • the invention relates to a device for feeding blanks of packaging material to a folding unit (folding turret) for the packaging of objects or groups of objects, the blanks being separable from a continuous material web by interacting knives (revolving separating knives, fixed counter-knives) and being fed to the folding turret are, as well as with a drive for the material web, in particular with draw rollers.
  • the older patent application P 37 21 459 proposes methods and apparatus for feeding packaging blanks to a folding unit, in which the production and therefore also the feeding of blanks to the folding turret is interrupted if and as long as objects, in particular stacks of paper handkerchiefs , the folding turret are not made available.
  • the device of this older problem solution is designed so that knives are arranged on two counter-rotating knife rollers. In one of these knife rollers, the cutting knives are adjustable in such a way that they are moved out of cutting engagement for the temporary interruption of the blank production, namely by pivoting the pivotably mounted cutting knives.
  • the invention has for its object to provide an improved alternative to the device according to older patent application P 37 21 459, which responds more quickly, especially when the supply of objects is interrupted, and immediately prevents the production of blanks with small, reliable adjusting movements of knives.
  • the device according to the invention is characterized by a rotating knife roller with at least one separating knife and by a fixed counter knife, the counter knife being movable out of engagement with the separating knife of the rotating knife roller when objects are not supplied.
  • the counter knife is attached to a knife arm, which can be pivoted by an actuating gear, in particular by an eccentric gear, and disengages the counter knife by the pivoting movement.
  • the adjusting movements of the counter knife are dependent on the movement of the constantly rotating knife roller.
  • This is provided with a cam disc to control the movement of an actuator for the knife arm or the eccentric gear.
  • the Ver pack of stacks of paper tissues but also of other objects. These are to be encased in a blank made of film material, for example a PE film.
  • the packaging material or the blank 10 is conveyed to the circumference of a folding turret 11, in the area of which the objects are wrapped in the blank 10 and the latter is folded.
  • the structure and mode of operation of the folding turret 11 result from DE-A-37 01 273.8.
  • the blanks 10 are successively separated from a preferably continuously conveyed material web 12. This is drawn off from a bobbin (not shown) and conveyed to deflection rollers 13, 14 and via a double rocker 15 to compensate for movement fluctuations to a separation station 16 for cutting off the blanks 10.
  • the material web 12 is conveyed at an essentially constant speed.
  • the separation station 16 is preceded by a pair of cooperating pull rollers 17, 18. At least one of these pull rollers 17, 18 is driven by a stepper motor 19, which causes the material web 12 to be precisely fed so that exact sections corresponding to a cut length can be conveyed.
  • the blanks 10 produced in the region of the separating station 16 are brought to the circumference of the folding turret 11 by a transfer conveyor 20.
  • the separation station 16 is formed in the core by a continuously rotating knife roller 21 and by a fixed or stationary counter knife 22.
  • the knife roller 21 is formed with two diametrically opposite cutting knives 23, 24 in the embodiment shown. As is generally customary, these are arranged such that their cutting edge protrudes slightly beyond the circumference of the knife roller 21. As a result, with the correspondingly positioned counter knife 22, a separating cut is made in the material web 12 passing between the cutting knife 23, 24 on the one hand and counter knife 22 on the other.
  • the knife roller 21 is designed as a suction roller with customary suction bores 25. These ensure an exact contact of the material web 12 on the circumference of the knife roller 21.
  • the knife roller 21 acts as a conveying element for the material web 12 or the blank 10, which acts on an intermediate conveyor roller 27, also designed as a suction roller with suction bores 26, is transferred. From this the blank 10 is forwarded to the transfer conveyor 20.
  • the function of the cutting members is interrupted, however, with the knife roller 21 and with subsequent conveying bodies also moved on.
  • the cutting function is interrupted here by the counter knife 22 (temporarily) being moved out of the cutting position.
  • the cutting knives 23, 24 can be moved past the stationary material web 12 without a separating cut being carried out.
  • the counter knife 22 is attached to a support arm 28 which can be pivoted about a pivot bearing 29 located away from the counter knife 22.
  • the support arm 28 is pivoted in the sense of lifting the counter knife 22 from the cutting position, in the illustration in FIGS. 1 and 2 clockwise.
  • These lifting movements of the counter knife 22 with support arm 28 take place against the load of a strongly prestressed compression spring 31, by means of which the support arm 28 and thus the counter knife 22 are loaded in the direction of the cutting position.
  • the counter knife 22 executes small lifting movements, in cycles, namely each time the cutting knife 23 or 24 moves past the counter knife 22.
  • the support arm 28 or the counter knife 22 are accordingly adjusted in cycles, namely controlled by the rotary movement of the knife roller 21.
  • the counter knife 22 accordingly carries out pulsating lifting movements.
  • the actuator 30 does not act directly on the support arm 28, but rather via an intermediate gear, which is designed here as an eccentric gear 32. This is also driven pulsating or swinging. The actuating movements generated thereby are transmitted to the support arm 28 via a stop piece 33.
  • the actuator 30 is designed in the present embodiment as an actuating lever 34. This is connected to a pivot pin 35 of the eccentric gear 32, such that with a pivoting movement of the actuating lever 34, the pivot pin 35 and, via this, the eccentric gear 32 is adjusted in the sense of a lifting movement of the support arm 28.
  • a transverse pivot lever 36 is attached to the free end of the pivot pin 35.
  • the adjusting lever 34 is connected eccentrically to the pivot 35, such that pivoting movements of the adjusting lever 34 trigger corresponding movements of the pivot lever 36, which are transmitted to the pivot 35.
  • the movements of the adjusting lever 34 are controlled by the rotary movement of the knife roller 21.
  • a cam 38 is also rotated. This is formed in the area of the cutting knives 23, 24 with adjusting cams 39.
  • a feeler roller 40 at the free end of the actuating lever 34 runs on the circumference of the cam disc. In the area of the adjusting cams 39, pivoting movements of the adjusting lever 34 are generated such that the counter knife 22 is briefly moved out of the cutting position.
  • the adjusting device for the counter knife 22 is ineffective.
  • the adjusting lever 34 or its feeler roller 40 can be moved out of engagement with the cam plate 38.
  • the adjusting lever 34 is therefore (additionally) pivotable in a transverse plane, namely about a pivot bearing 41. This is formed by a bearing pin 42 with which the adjusting lever 34 is also fastened to the pivot lever 36.
  • the adjusting lever 34 is provided with a side-facing extension 43, on which an actuating element for pivoting the adjusting lever 34 engages around the pivot bearing 41.
  • the actuating member is an actuating cylinder 44 which is articulated and fixed in place (machines frame 45) and its piston rod is pivotally connected to the shoulder 43 of the actuating lever 34.
  • the approach 43 is here provided with a connecting pin 46 on which the end of the piston rod is rotatably mounted.
  • the actuating cylinder 44 is set in motion by a corresponding signal such that the actuating lever 34 is pivoted from the starting position shown in broken lines in FIG. 3 into the actuating position shown in solid lines.
  • the sensing roller rests on the circumference of the cam disk 38 and transmits the described actuating movements to the eccentric gear 32.
  • the actuating lever 34 is pivoted out of engagement with the cam disk 38 again.
  • the counter knife 22 is thereby continuously positioned in the cutting position.
  • two support arms 28 are arranged at a distance from one another and connected to one another by a resilient cross member 47.
  • the cross member 47 is designed as a hollow body.
  • the counter knife 22 is attached to one side thereof.
  • the support arms 28 are each mounted with a pivot 48 in a fixed cheek 49 of the machine frame 45 to form the coaxial pivot bearing 29.
  • the eccentric gears 32 assigned to the two support arms 28 are designed to match and are connected to one another.
  • An eccentric pin 50 is attached to the pivot pin 35 in a staggered manner. On this a ball bearing ring 51 is arranged, which is moved up and down when the pivot pin rotates and transmits the lifting movements to the stop pieces 33.
  • the eccentric pins 50 of the two eccentric gears 32 are connected to one another by a connecting shaft 52. This runs within the hollow traverse 47 and is used for Transmission of the swivel movements of the drive (swivel lever 36), which is only arranged on one side, to the opposite eccentric gear 32.
  • the pivot pin is rotatably mounted in the cheek 49.
  • the cut blanks 10 are transferred from the knife roller 21 designed as a conveyor roller to the intermediate conveyor roller 27.
  • a punching roller 54 comes into effect, by means of which punchings or perforations are made in the blanks 10, e.g. for an opening tab.
  • the punching roller 54 can be equipped with approximately radially directed knives 55, which are removably attached in a sufficiently dimensioned recess 56 of the punching roller 54.
  • the arrangement is such that the knives 55 can be easily replaced.
  • punch knives 57 can be attached to the punch roll 54, also in a corresponding depression 58. These punch knives 57 extend along a partial circumference of the punch roll 54 and are designed to generate complex perforation or cutting images in the blank 10 .
  • two punching knives 57 of this type which are arranged at a distance from one another, are detachably fastened, namely with screws 59.
  • the actual punching tool or a punching edge 60 is designed in the form of a truncated V for production a corresponding perforated punching in the blank 10.
  • the arrangement of two of these tools on the common punching roller 54 serves the two-lane operation of the device. This is accordingly aligned so that a double-wide material web or two material webs corresponding to the width of a blank 10 are fed to the separating station 16 and that accordingly two blanks 10 are produced and fed to the folding turret 11.
