Definitions

  • the invention relates to a method for packaging a Roll of material in which a packaging web at least beginning with the help of an adhesive in contact with the circumference of the roll of material held and the web roll rotated becomes.
  • the invention further relates to a device for packaging a roll of material according to the preamble of Claim 8.
  • the invention is based on a paper web roll described as an example of a web roll. But in principle it is also with others Material web rolls applicable, for example at Rolls of plastic or metal foils or at Rolls of cardboard sheets.
  • the web rolls to be packaged have a considerable amount Size. Their diameter is usually in the range from 500 to 2,100 mm. The roll width is usually 500 to 3800 mm or even more out.
  • Such web rolls arise, for example in paper or textile production.
  • the packaging line offers mechanical protection against damage. On the other hand, it should also influence of environmental factors such as air humidity.
  • the invention has for its object a roll of material web easy to pack without damaging the surface.
  • This task is carried out in a method of the aforementioned Art solved in that the packaging web with Help one predominantly cohesive adhesive, which leaves no residue on the roll of material is peelable with the circumference of the roll of material is releasably connected.
  • a pressure sensitive adhesive that is suitable for this application is for example called "JOVATEX” by the Jowat Lobers and Frank GmbH & Co. KG, Wittekindstrasse 19, D-32709 Detmold.
  • the pressure sensitive adhesive provides on the one hand a connection between the packaging line, at least its beginning, and the extent of Material web roll safely. This connection is stable enough to mark the beginning of the packaging line for so long Hold the circumference of the material web roll until one subsequent position of the packaging line additional forces can exercise on the situation forming the beginning. It so it's only a relatively short period of time, namely until the material web roll a little more than a complete revolution. If the roll of material should be unpacked, then can usually the one formed by the packaging web Destroy wrapping.
  • the pressure sensitive adhesive is preferably applied to the packaging web applied.
  • the adhesive is applied shortly before connecting the packaging web with the roll of material so that the pressure sensitive adhesive first connects to the packaging line and only makes their surface sticky.
  • the adhesive then remains on the packaging web and not on the circumference of the web roll. The scope the material web roll remains practically residue-free clean.
  • the packaging web is preferably covered by at least a nip between the web and a driven one Roller guided.
  • This nip serves two purposes. First, he presses the tacky packaging web to the circumference of the roller. This will make the Packaging web also with a pressure sensitive adhesive that has a lower Holding force than a previously used Hot or cold glue, with sufficient strength with connected to the scope of the roll of material. Because the roller is driven, the packaging line above it driven out by the roller so that the junction between the beginning of the packaging line and not excessively the extent of the web roll Tensile forces is loaded. The "pulling" of the packaging line So at least at the beginning it doesn't just happen by rotating the web of material, but also by the driven roller on the packaging line acts.
  • the material web roll advantageously lies on the driven one Roll up. You then use your own weight the web of material, a certain contact pressure to produce in the nip or nip. Further Measures are not necessary.
  • the packaging web is advantageously made up of several layers Roll of material web led around, one each external position with the one below Layer non-detachably bonded with another adhesive.
  • the term "unsolvable” refers to the fact that one when disconnecting the connection made with this adhesive risks damaging at least one of the Bring about surfaces of the packaging web.
  • this configuration saves you the relatively complicated start-up tools the packaging line, so that the additional load easily in Purchase can be made. Because the locations of the Packaging web are now firmly connected to each other, you get a very stable packaging with which it doesn't matter that the beginning of the packaging line only a relatively weak adhesive connection to the circumference the web roll.
  • the packaging web is advantageously helical led around the web roll.
  • Words have the longitudinal edge of the packaging web predetermined angle to the circumferential direction of the material web roll on.
  • Such a packaging process is known for example from DE 195 35 746 C2. With such packaging, it is acceptable Effort practically impossible, the beginning of the packaging line around the perimeter of the web roll until the next layer reaches to the beginning hold.
  • the use of the pressure sensitive adhesive mentioned is a good alternative if you have the firm Gluing the beginning of the packaging line with the Want to avoid the extent of the web roll.
  • the pressure sensitive adhesive is preferably sprayed on.
  • the spraying has the advantage that the pressure sensitive adhesive when applied already a relatively intensive contact with the Air and thus with the atmospheric oxygen.
  • the spraying So make sure that the pressure sensitive adhesive is relative quickly has a high adhesive strength, so that you already a short time after applying the pressure sensitive adhesive sufficiently stable adhesive connection between the beginning the packaging web and the scope of the material web roll can reach.
  • the object is achieved in a device of the type mentioned Art solved in that the storage vessel one predominantly cohesive adhesive contains the residue-free from the web roll is removable.
  • the pressure-sensitive adhesive dispenser is preferably used as a spray device educated.
  • the pressure sensitive adhesive can then Apply enough to be oxidized develop its adhesiveness.
  • the pressure device is preferably provided by a nip between the web roll and a driven one Roller formed.
  • the pressure device then has one second task. After the tackified area between the material web roll and the packaging web the driven roller serves the nip this nips to replenish the packaging line. Accordingly, the load on the joint between the material web roll and the packaging web kept small.
  • the material web roll preferably lies on the roller on. So you use the weight of the web roll to generate a contact pressure.
  • the packaging web dispenser preferably gives the packaging web at a predetermined angle to the circumferential direction the web of material.
  • the packaging web is helical guide around the roll of material. This has the advantage that you can also with different widths the material web roll with a single packaging web gets along, for example with a packaging line a width of 500 mm. The stockpiling is accordingly the packaging line much easier. Only packaging web rolls of the same need to be Art, for example with a width of 500 mm, kept ready become.
  • the helical packaging complicates usually connecting the start of the packaging line with the material web roll if you click on a fixed gluing dispensed with. By using the However, pressure sensitive adhesives will elegantly address this problem Way solved.
  • the material web roll 2 is here on two support rollers 4, 5 stored, of which the support roller 5 with the aid of a drive 6 is rotatable. When the support roller 5 rotated the material web roll 2 also rotates.
  • the packaging web 3 passes through the nip between the support roller 5 and the web roll 2.
  • the packaging web 3 is wound on a supply roll 7, which are arranged on a packaging web dispenser 8 is.
  • the packaging web dispenser is on rails 9, 10 can be moved parallel to the material web roll 2. It is also in its angular position relative to the roll of material web 2 adjustable. In the shown in Fig. 1 The angular position closes the width direction of the packaging web 3, i.e. the axial direction of the supply roll 7, an acute angle with the axial direction of the web roll 2 a. So if you look at the packaging line 3 in this orientation between the web of material 2 and the support roller 5 and inserted on the web roll 2 attached, then results when turning the web roll 2 in the direction of arrow 11 helical packaging of the web roll 2 with the packaging line 3. This is schematically in Fig. 1 shown.
  • the packaging web 3 has a much smaller one Width than the material web roll 2, for example 500 mm, while the material web roll widths up to approx. 3.8 m can accept.
  • the Packaging web 3 retraced and wraps helically on the circumference of the material web roll 2 on. It is a prerequisite that at least the Start of the packaging web 3 on the circumference of the roll of material web 2 is recorded. Holding on is however only necessary until the roll of material web 2 a little more than one turn Has. Then the packaging web 3 is at least on part of its width from a subsequent turn covered, which then forms a second layer and the Packaging web 3 presses against the web roll 2. Of course, it does no harm if the start of the packaging line 3 also with further winding on the circumference of the Material web roll 2 is held.
  • an adhesive application station 12 provided, schematically in Figs. 1 and 3 is shown.
  • 3 is the packaging web 3 shown twice for reasons of clarity, once under the adhesive application station 12 and once on the web of material to be packed 2. This illustration, in which the packaging line 3 can be seen once from the front and once from the side, was only chosen for reasons of clarity. In In reality, the packaging line 3 runs in a straight line the adhesive application device 12 to the web of material web Second
  • the adhesive application station 12 has a carrier 13 on, which is arranged slightly above the packaging web 3 is. This makes it possible to top 14 of the Packaging web 3 to be provided with adhesive. This The top then comes along in the direction of gravity the web roll 2 in contact and is by the Carrier rollers 5, 4 pressed onto the material web roll 2.
  • the adhesive application station 12 has a first adhesive application device 16 and a second adhesive application device 15 on.
  • the first adhesive application device 16 protrudes a line 26 and a pump 27 with a storage vessel 28 in connection. It has spray nozzles 29, which a valve 30 is also connected upstream. If that Valve 30 is opened, for which purpose a control device 23 comes into action, then a spray jet 31 arises, through the adhesive to areas 32 on the top 14 of the packaging web 3 arrives.
  • the storage vessel 28 contains a special adhesive, namely a pressure sensitive adhesive.
  • a pressure sensitive adhesive is used, for example by Jowat Lobers and Frank GmbH & Co. KG, Wittekindstrasse 19, D-32709 Detmold, under the name "JOWATEX” offered. It is usually used to manufacture removable protective films suitable and is based on a copolymer.
  • the areas are 32 flat. They extend almost across the entire width of the packaging web 3, a certain Distance to the edges is maintained by one Avoid pollution of the environment.
  • the direction of movement of the packaging web 3 are the areas 32, on the other hand, is relatively short, i.e. they listen briefly the front edge 33 of the packaging web 3 again. But they can also be so long that they are the circumferential length correspond to the web roll 2. This is but usually not necessary.
  • the packaging web 3 to the material web roll 2 is brought to the plant, then it already receives when passing through the first nip between the Carrier roller 5 and the material web roll 2 have a high initial adhesive strength, through the second pressing further reinforced by the support roller 4. Usually it is sufficient if the area 32 has a length that corresponds to the distance between the two support rollers 4, 5. In In certain cases, the area 32 can be even shorter his.
  • the here on the connection forces can be kept small be that the support roller 5 is driven.
  • the remaining Forces, such as gravity or centrifugal force, are so small that they can be handled by the pressure sensitive adhesive can.
  • the second adhesive application device 15 protrudes a line 19 and a pump 20 with a storage vessel 21 in connection.
  • the pump 20 takes out here Adhesive, for example a conventional cold glue from the storage vessel 21 and conveys it under pressure through line 19.
  • the second adhesive applicator 15 here has valves 22, which also opened and closed by the control device 23 can be. Accordingly, the valves 22 give the Adhesive in the form of drops 24 off.
  • the control device 23 also stands with the drive 6 of the support roller 5 in Connection. So it is about the peripheral speed the web roll 2 and thus also on the Feed speed of the packaging web 3 informed.
  • the valves 22 are controlled so that the adhesive application temporally depending on the speed the packaging web 3 varies. It is becoming more precise said so controlled that the application of adhesive per unit length the packaging web 3 is constant or at least remains in a predetermined target corridor.
  • Glue beads 25, here as a sequence of drops of adhesive 24 are shown.
  • the drops of glue can touch, for example when they are putting on the packaging web 3 to the material web roll 2 be squeezed wide. This is beneficial, however not necessarily.
  • Two of the glue beads 25 are Edge of the packaging web 3 as close as possible. It can also do more than the three glue beads shown 25 be present.
  • the areas 32 at the beginning the packaging web 3 reliably on the circumference of the material web roll 2 cling.
  • the second adhesive application device 15 in Be put into operation This then only ensures that the subsequent packaging web layers on the each of the packaging sheet layers below can be glued so that a firmly attached and packaging that can be handled consistently. If the areas 32 should come loose later, this no longer matters.
  • the one from the packaging line 3 tension applied to lower layers is sufficient to keep the packaging securely on the circumference of the material web roll 2 to hold on to.
