Definitions

  • the invention relates to a method for producing a peripheral packaging for a roll of paper. It also relates to a method for producing a front side packaging for a paper roll and a method for producing a packaging for a paper roll.
  • the paper roll each has a wound paper web and two opposite end faces and a peripheral surface that connects the end faces with one another.
  • Such paper rolls have long been known from the prior art and are used, for example, in the paper and printing industries. They can be unprinted, for example as raw paper rolls, or printed as paper rolls. Typically they are used to transport long webs of paper, which can be several kilometers long, from one manufacturing location to another location where they are further processed. To ensure that the paper rolls are not damaged during transport, they must be packaged and protected. For this purpose, the paper rolls are usually removed from their production facility so that their front sides are accessible without axis. Handling the rolls is complex and requires large machines, as each individual roll can weigh up to 1.5 t.
  • the packaging is packed in a separate packaging machine that can be operated automatically or semi-automatically. In individual cases, paper rolls are also packed manually.
  • the packaging usually consists of peripheral packaging intended to protect the peripheral surface of the paper roll.
  • the packaging usually also has two front packaging.
  • peripheral packaging is conventionally made from two layers of brown paper with a basis weight of, for example, 100 g/square meter, where A waterproof layer, for example a polyurethane layer, can be arranged between the two paper layers. This is applied, for example, with a basis weight of 20 g/square meter.
  • peripheral packaging can also be in the form of a film that is placed around the paper roll in order to protect it from external influences, especially moisture.
  • the film can also be reinforced with a reinforcing layer, for example made of cardboard, in order to achieve mechanical stability and to protect the paper layer against knocks and impacts, for example.
  • a front packaging is conventionally used in the form of a coated cardboard lid, the diameter of which corresponds at least approximately, but preferably completely, to the diameter of the paper roll.
  • Such end covers protect the end faces of the paper roll against external influences.
  • a front cover either has a foldable edge protection itself, for example in that the diameter of the front cover is larger than the diameter of the paper roll to be packaged. In this case, the front cover protrudes and can be folded down. The unclarified part then forms the edge protection.
  • a separate edge protector is used, which is glued at the transition from the front cover to the peripheral packaging.
  • EP 0 655 389 A1 is a method for packaging a roll of material web, in which a packaging web is used in which the roll of material web is wrapped.
  • the packaging web is provided with a water-soluble adhesive to surround the packaging around the roll of material web.
  • a similar process, in which one end face of a roll of material web is closed with an end cover, is from the EP 2 151 388 A1 known.
  • the invention is therefore based on the object of improving methods for packaging a paper roll so that they can be carried out quickly, easily and inexpensively and still ensure good and safe packaging of the paper roll.
  • the method according to the invention can be carried out, for example, in the production plant, in particular within a printing line, in which the paper roll is produced, i.e. the paper web is processed and rolled up.
  • an additional applicator is preferably used, through which the protective material can be applied in liquid form to the paper web, in particular to the end section of the paper web.
  • This can be, for example, an anilox roller with a scoop trough from which the protective material is scooped with the anilox roller.
  • a squeegee can be provided which strips excess protective material from the anilox roller.
  • the protective material is preferably applied from the anilox roller to an applicator roller, for example a rubber roller, which then brings the protective material to the end region of the paper web.
  • an applicator roller for example a rubber roller
  • the application work is, for example, a print head, for example a digital printing system, a laminating system or a laminating system.
  • the protective material is applied in liquid form and, when cured, preferably has protective, in particular water-repellent, properties. Waxes, resins or plastic, for example, can be used as protective materials Polyurethane (PU) or polyethylene (PE).
  • the protective material can be pigmented or colored to reflect individual needs and preferences.
  • the protective material can also be designed in different colors, so that protective material of different colors can be applied, for example, to different locations on the end section. This opens up further visual design options. This is particularly advantageous for the protective material that is applied to the part of the end section that is visible from the outside after the protective material has hardened. Inscriptions or bar or QR codes can also be applied in this area by using differently colored protective material. This is particularly easy if the at least one commissioned work is a digital printing work.
  • the amount of protective material applied is advantageously at least 3 g/square meter, preferably at least 5 g/square meter, particularly preferably at least 8 g/square meter and at most 50 g/square meter, preferably at most 30 g/square meter, particularly preferably at most 15 g/square meter.
  • the protective material can be applied to one side of the end section of the paper web or to both sides of the end section of the paper web, i.e. a top and a bottom of the paper web.
  • At least one sensor and an electronic control can be used to monitor that the desired amount of protective material has been applied and the desired distribution of the protective material can also be monitored in this way.
  • a further printing unit can be downstream of the applicator in order to be able to print information, for example about the contents of the paper roll, a delivery location or other information, onto the protective material, which has then preferably already hardened.
  • the at least one commissioned work can be a digital commissioned work or an analog commissioned work.
  • the application of the protective material is monitored using at least one sensor, preferably using several sensors.
  • the result is preferably used to detect and correct any deviations from a predetermined target order quantity.
  • the result of the monitoring is preferably stored, particularly preferably stored electronically. This means that in the event of later problems or complaints, it can be traced whether sufficient protective material was used.
  • the end section is so long that when it is wound up, it forms several outer layers of the paper roll, preferably at least three outer layers, particularly preferably at least five outer layers, more particularly preferably at least seven outer layers of the paper roll.
  • the length of the end section is at least 3 m, preferably at least 5 m, particularly preferably at least 8 m, and at most 100 m, preferably at most 40 m, particularly preferably at most 20 m.
  • a marking is advantageously applied to the paper web, which forms the beginning of the end section.
  • This marking can preferably be edited electronically after it has been recorded automatically, for example optically by a camera.
  • An electrical or electronic control of the system recognizes the marking and generates control signals with which the application mechanism for the protective material is controlled so that the protective material can be applied to the end section of the paper web, which is identified by the marking.
  • the protective material is preferably hardened before the end section is wound up.
  • the paper of the paper web coated with the protective material is preferably dried by a drying device or a curing device be guided.
  • the coated paper can be irradiated with infrared light, UV radiation, heat or other radiation to accelerate curing.
  • crosslinking or polymerization of the protective material is also understood as curing. If the protective material is hardened before it is wound up, the hardened protective material can be printed particularly easily.
  • the end section is wound up before the protective material has completely hardened, so that the protective material preferably connects a plurality of outer layers of the paper roll formed by the end section to one another during hardening. This does not result in several separate layers with hardened protective material, but rather the protective material from different layers combines when hardening, crosslinking or polymerizing and forms a single thicker and therefore safer protective layer.
  • a web of paper which can be several kilometers long, is wound on a shaft.
  • This shaft is mounted at least on one end face of the paper roll, but preferably on both end faces of the paper roll. This allows the large forces, which on the one hand are caused by the large mass of the Paper roll and, on the other hand, caused by the high rotation speeds of the paper roll when winding up, are intercepted. In this condition, however, it is not possible to pack the entire front side of the paper roll because the shaft protrudes from the front side.
  • a front cover which was made, for example, on a paper basis and preferably contains a cardboard which is coated with a coating, in particular a waterproof coating.
  • a coating can be made, for example, from a polyurethane (PU) or a polyethylene (PE).
  • PU polyurethane
  • PE polyethylene
  • a tab is understood to be a flat element that covers the opening in the front cover.
  • the end cover is preferably at least almost, but preferably exactly, circular and, in a first embodiment, has an opening that is punched out, for example.
  • an end cover is placed on the shaft by passing the shaft on which the paper web is to be wound up through the opening.
  • two such end covers are placed on the shaft, with the paper web then being wound between the two end covers and the paper roll is created.
  • the front cover has an indentation in which its shape deviates from that of a circle.
  • the indentation advantageously extends radially inwards from the edge of the end cover.
  • the indentation particularly preferably extends beyond the center of the circular cover.
  • the opening is a hole through which the shaft can be inserted and which is connected to the edge of the end cover by a cut. This cut preferably replaces the indentation.
  • the cover has two cover halves, which are arranged so that they form a hole between them, through which the shaft extends in the arranged state.
  • the cover halves are preferably designed identically, so that two cover halves can be assembled to form a base body.
  • differently designed cover halves can also be used, which together form a base body.
  • the tab of the end cover can be designed as a separate element and preferably consist of the same material or the same combination of materials as the rest of the end cover. It is preferably slightly larger than the opening in the base body of the end cover that it is intended to cover, so that the edge of the tab can be connected to the edge of the indentation, for example glued.
  • the tab and the base body are formed in one piece with one another.
  • the tab is connected to the base body over at least part of its circumference along a dividing line, which preferably has a perforation, the tab preferably having to be separated from the base body along this dividing line before the end cover is pushed onto the shaft.
  • the dividing line forms the boundary between the base body and the tab and thus the opening of the base body.
  • the end cover can be provided in a one-piece state, with the tab and the base body preferably not yet being separated along the dividing line.
  • the front cover has a preferably circular shape. If the end cover is now to be arranged on the shaft, the tab is separated from the base body along the dividing line, which is particularly easy due to the preferably existing perforation. This creates the opening, preferably the indentation, into which the shaft can be inserted. It has proven to be particularly advantageous if the tab continues to be connected to the base body of the end cover even after it has been separated along the separating line. In this case, the dividing line does not extend around the entire circumference of the tab, but only over part of this circumference. The tab can then be separated from the base body of the end cover along the dividing line and, for example, folded over, the fold line corresponding to the connecting line between the base body and the tab.
  • the tab has a first part for covering a first part of the indentation and a second part for covering a second part of the indentation, the first part of the indentation being covered by the first part of the tab before the paper roll is removed from the shaft .
  • the two parts of the tab preferably adjoin one another in the radial direction.
  • the first part is arranged radially on the outside and the second part is arranged radially on the inside.
  • the two parts can preferably be separated from one another by a second dividing line, which can also have a perforation.
  • the tab is preferably separated from the base body along the first dividing line.
  • the second dividing line between the two parts of the tab is separated and the first part of the tab, which is located radially on the outside, can be folded over.
  • the first part of the tab is then preferably again along the part of the first dividing line which runs along this part of the tab connected to the base body of the end cover, so that the first part of the indentation is covered and the part of the paper roll covered thereby is protected.
  • the end cover therefore has the recess through which the shaft extends.
  • the second part of the tab is also folded over to cover the second part of the indentation.
  • the width of the indentation i.e. its extent in the circumferential direction, preferably corresponds to at least the diameter of the shaft.
  • the base body and the tab are made from a paper material or cardboard material coated with a protective material.
  • two front side packagings are produced for one of the two front sides of the paper roll.
  • These two end packagings are each connected to the peripheral packaging so that the paper roll is completely packed and protected against external influences.
  • the protective material used for the perimeter packaging and the protective material used for the end packaging are identical.
  • a diameter of at least one end cover is larger than the diameter of the paper roll.
  • part of the front cover is folded over onto the peripheral packaging in order to connect the front packaging with the peripheral packaging.
  • an additional edge protection element can be used, for example, to provide greater protection for the sensitive edges of the paper roll, especially against mechanical influences from outside.
  • edge protection is therefore applied along the edges of the paper roll, along which the peripheral surface adjoins the end faces, after the peripheral packaging has been connected to the at least one end packaging or in order to connect the peripheral packaging to the end packaging.
  • the second alternative is particularly advantageous if the diameter of the front packaging is not larger or not sufficiently larger than the diameter of the paper roll.
  • the invention also solves the problem set by a device for carrying out a method described here for producing a peripheral packaging, a device for carrying out a method described here for producing an end-side packaging and/or a device for carrying out a method described here for producing a packaging for a paper roll.

  • the printing system had an additional applicator with a ceramic anilox roller, a scoop tray and a squeegee with a scoop volume of approx. 8 g/square meter.
  • This commissioned work was arranged in the production direction behind a drying device in which the applied digital print was dried by irradiation with NIR radiation (NIR: near infrared).
  • the application medium that was applied in the applicator factory contained PE components and brown color pigments.
  • the production order was designed for 10,000 running meters. A flag was automatically placed by a labeling machine at the point on the paper web that corresponds to the ten thousandth running meter. This flag was recognized by a machine, so that the additional application unit for coating with the PE protective material was switched on without the entire system having to be stopped.

  • the paper web 2 with the protective material 10 passes through a second drying device 18, in which the protective material 10 is dried before the paper web 2 processed in this way is wound onto a shaft 20 of a roll winder.
  • the application of the protective material 10 is monitored via sensors 22, which are connected to an electronic control 24.
  • Figure 2 shows schematically how the material of the paper web 2 coated with the protective material 10 is wound onto the shaft 20. Radially inside there is a white area, which shows that a large part of the paper web 2 has already been wound up and has not been coated with the protective material 10.
  • the protective material 10 is completely cured before the end region of the paper web 2, which has been coated with the protective material 10, is wound up. Therefore, as in Figure 2 is shown, seven separate layers of the paper web 2 coated with the protective material 10.
  • Figure 3 shows another embodiment.
  • the protective material 10 has been applied to the paper web 2.
  • it has not been completely dried, so that the different layers of the paper web 2, which have been coated with the protective material 10 and are now being wound up, are bonded into a single protective layer as the protective material 10 of the different layers bonds together. Therefore, compared to Figure 2 just a single layer of protection while in Figure 2 seven separate protective layers are created.
  • Figure 4 shows a front cover 26. It has a base body 28, which is formed in one piece with a tab 30.
  • a first dividing line 32 which is designed as a perforation, extends over part of the circumference of the tab 30.
  • a fold line 34 extends over a second part of the circumference of the tab 30.
  • the tab 30 in the exemplary embodiment shown in FIG. 4 has a first part 36 and a second part 38, which are separated from one another by a second dividing line 40.
  • Figure 5 shows that the tab 30 was separated from the base body 28 of the end cover 26 along the first dividing line 32 and folded upwards along the fold line 34. An indentation 42 is created so that the end cover 26 can be pushed onto the shaft 20.
  • the second dividing line 40 is still undamaged in this method step and the two parts 36, 38 of the tab 30 are not yet separated from one another.
  • Figure 10 shows schematically a further embodiment of an end cover 26.
  • the opening 44 is designed in the form of a hole that is large enough to fit into Figure 10 to record wave 20, not shown.
  • the end cover 26 has a cut 46 which extends from the outer edge 48 of the end cover 26 to the opening 44.
  • the material of the end cover 26 is designed to be so flexible that no fold line is required to open the end cover 26 along the cut 46 and push it onto the shaft.
  • Figure 11 shows the base body 28 of an end cover 26.
  • the base body 28 is composed of two cover halves 50.
  • In its center is the opening 44, through which the shaft 20, not shown, extends when the end cover 26 is in place.
  • the two cover halves 50 are identical. This is an advantage, but not necessary.
  • the two cuts 46 do not necessarily have to be arranged opposite one another and symmetrically to the center of the opening 44.
  • Figure 12 shows schematically a base body 28 of an end cover 26, with the specific design of the base body 28 not being shown.
  • Figure 12 illustrates the outer edge 48 of the base body 28, on which an edge protection 52 is located. In the exemplary embodiment shown, it has a fastening ring 54 with which the edge protection 52 is fastened, for example glued, to the base body 28 of the end cover 26.
  • the edge protection 52 has a plurality of folding tabs 56, which in the exemplary embodiment shown are distributed equidistantly over the circumference. This is an advantage, but not necessary. Also one Irregular arrangement of the folding tabs 56 is possible. They protrude beyond the outer edge 48 of the base body 28 and are used to connect the front packaging, which is reached through the front cover 26, to a peripheral packaging. For this purpose, the folding tabs 56 are folded over and attached to the peripheral packaging, for example glued.
