Definitions

  • the invention relates to a method according to the preamble of Claim 1 and a device according to the preamble of the claim 6.
  • Such a method and such a device are known from the GB 1 429 445 B.
  • the process has the mentioned type the advantage that a packaging web one certain small width used for rolls of any length can be. This simplifies storage and handling of packaging web rolls.
  • the invention is therefore based on the object of a method and a device for packaging a roll with a packaging web, whose width is less than the length of the roll, to be designed in such a way that the roll is essentially wrinkle-free is wrapped, even if the packaging web is not elastic and is not shrinkable, especially if it is made from ordinary Wrapping paper exists.
  • the device shown has the task of a cylindrical Pack roll 10, its axis A and its length L in Fig. 3rd to 5 are shown.
  • the role 10 consists of, for example Printing paper and has a first one in the above drawings left end 12 and a second, right end 14, both as flat end faces are formed.
  • the role is in the company 10 on two parallel support rollers 16 and 18, which in the sense of Arrows in Fig. 1 are driven.
  • a packaging web 20 is used to pack the roll 10 Wrapping paper, the width B of which is considerably smaller than the length L of roll 10.
  • This packaging web 20 is first according to Fig. 3 at right angles to the axis A of the roller 10, while this is rotated, the cylindrical surface of the roller in such a way supplied that one consisting of preferably several turns first straight wrap 22 is formed.
  • a second straight wrap 24 is formed from the same packaging line 20 will later be shown in FIG. 5 in the area of the second end 14 of the roll 10.
  • Both straight windings 22 and 24 protrude by approximately each half the width B of the packaging web 20 over the associated one End 12 or 14 of the roll 10 out; so it will be a first Overhang 26 or a second overhang 28 approximately from the Width B / 2 formed.
  • the two straight wraps 22 and 24 are as follows through a helical winding 30 of the roll 10 connected with each other:
  • first incision 32 which of the second end 14 of the Roll 10 facing edge of the packaging web 20 starts out transverse to their longitudinal direction over the greater part of their Width B extends and ends in the part of the packaging web 20, which then form the first overhang 26, ie beyond of the first end 12 of the roll 10 will lie.
  • first incision 32 a place where it is roughly in the same vertical plane lies like the axis A of the roller. Now it is on roll 10 tapered part of the packaging web 20 inclined so that it 4 an acute angle ⁇ with the Axis A forms.
  • the packaging web 20 is parallel to the axis A further rotating roller 10 on its peripheral speed matched, laterally offset, so that the helical wrap 30 arises.
  • the angle ⁇ is chosen so that the individual Windings of the helical wrap 30 overlap each other.
  • a relatively small overlap is shown in FIG. 5; however, the overlap can be significantly larger, for example half of the width B of the packaging web 20.
  • a second incision 34 is made in the packaging web 20, the edge facing the roller 10 from the first end 12 the packaging web runs out, transversely to its longitudinal direction extends over the greater part of their width B and in one Area ends, which then form the second projection 24 becomes. Then the part of the packaging web that runs towards the roll 10 20 again set at a right angle to axis A, so that with continued rotation of the roller 10, the second just winding 24 with its overhang 28 is formed.
  • the two cuts 32 and 34 prevent that in the packaging line 20 annoying folds arise when the angle the Packaging web on its way to roll 10 with its axis A includes, at the transition from the first straight wrap 22 to the helical wrap 30, and at the transition from this changed to the second straight wrap 24 according to FIG. 4 or FIG. 5 becomes.
  • a first overlap field 36 and a respectively second overlap field 38 both of which are approximately triangular.
  • two of the first incision 32 or delimited by the second incision 34 triangular surfaces of the packaging web 20 one above the other without To form wrinkles.
  • This desired stacking can be done with Need to be enforced by the affected areas of the Packaging web 20 of one or more air flows or by sucking in opposite directions out of the plane be deflected in the process of making the one that separates them Incisions 32 and 34 were located.
  • the incisions 32 and 34 do not tear away unintentionally, they each end in a punched circular hole 40. Beyond this hole 40 may be in the extension of the relevant incision 32 and 34 in the described Changes in the feed direction of the packaging line 20 small Wrinkles; but these are in the supernatant 26 and 28, respectively in a later step in the usual way radially inwards is handled. The wrinkles mentioned remain without any influence on the smoothness and roundness of the wrapped surface roll 10.
  • the device shown schematically in the drawings is suitable with a carriage 42 that is parallel to the two Back-up rolls 16 and 18 and thus parallel to the axis A of the roll 10 along guides 44 is controlled displaceable.
  • the sled 42 carries a roll-off device 46 on which a packaging web roll 50 axially parallel to the roll 10 to be packed , and a pair of drive rollers 52 and 54, which is the packaging web running off the packaging web roll 50 20 with precisely controllable speed in the direction on the roll 10 to be packed perpendicular to its axis A promote.
  • the drive rollers 52 and 54 can be controlled that their peripheral speed is optionally the same size, slightly less or slightly greater than the peripheral speed of the packing roll 10 is.
  • the packaging web 20 whenever they is provided with an incision 32 or 34, and at least until the overlap field belonging to the relevant incision 36 or 38 completely on the roll to be packed 10 abuts, driven at a speed that is something is greater than the peripheral speed of the roll.
  • the carriage 42 carries a cutting device, the one Knife roller 56 and a complementary counter-knife roller 58 having. These two rollers 56 and 58 also extend parallel to the axis A of the roll 10 to be packed and are synchronously driven by a stepper motor as well as adjustable towards and away from each other.
  • the knife roller 56 carries three parallel to its axis, 120 ° against each other offset knife, namely a usable over the entire Length of the knife roller continuous cutting knife 60 and a first Cutting knife 62, which is used to make the first incision 32 is provided and accordingly from one first end of the usable length of the knife roller 56 only up to extends near its second end, and a second incision knife 64, which is used to make the second incision 34 is provided and accordingly from the second end of the Knife roller 56 extends only in the vicinity of its first end.
  • Each of the two incision knives 62 and 64 ends in a punch 66 or 68 for punching the hole 40 at the end of the first incision 32 and the second incision 34.
  • the carriage 42 carries a feed device 70 which the Determines the angle at which the packaging web 20 of the outer surface the roll 10 is fed.
  • the feed device 70 has a deflecting roller 72 leading the packaging web 20 to the is freely rotatably mounted on an axle body 74, which in turn on a U-shaped support bracket in the view according to FIG. 2 76 is attached.
  • the bracket 76 is at one end, in Fig. 2 left, mounted on a frame 78 which on the slide 42 is attached and the support bracket 76 near its opposite end supporting pneumatic or hydraulic Adjustment cylinder 80 carries.
  • the support bracket 76, and thus the deflection roller 72, from a horizontal to the axis A of the roller 10 parallel position, used for winding the straight wraps 22 and 24 serves to pivot into an inclined position 1 and 2 as the upper position with dash-dotted lines is indicated and causes that running over the deflection roller 72 Packaging web 20, the outer surface of the to be packaged Roll 10 reached at the selectable acute angle ⁇ to the axis A. So that the required tilting of the deflection roller 72 exactly predetermined and then in each case by pressing the Adjusting cylinder 80 reached quickly and just as quickly again can be left is a separate one from the adjustment cylinder Control device is provided, the one adjusting motor 82 and one of this controlled stop 84 for the bracket 76.
  • Adhesion mediation device 86 may be arranged, for example an adhesive sprayer that is in front of and / or behind each the incisions 32 and 34 apply adhesive so that each one Overlap field 36 or 38 forming surfaces of the packaging web 20 are glued together.
