Definitions

  • the invention relates to a method for packaging a material web roll, in which the material web roll is encased with a packaging web with a width adapted to the width of the material web roll, the surface of which is made at least in sections adhesive before being placed on the material web roll, and a device for packaging a material web roll with at least one unwind station for a packaging web, a preferred device, a knock-off device, an adhesive transfer device and a winding station, the packaging web having a width adapted to the width of the material web roll being able to be guided from the unwind station through the other devices to the winding station.
  • the preferred device pulls the packaging web off a storage roll stored in the unwinding station and conveys the packaging web in the direction of a nip which is formed by the web of material web to be packaged and a carrier roller carrying it.
  • a nip which is formed by the web of material web to be packaged
  • a carrier roller carrying it.
  • several packaging web rolls of different widths are stored in the unwind station in order to be able to adapt the width of the packaging web to the width of the material web to be packed.
  • the side of the packaging web facing the material web roll which is referred to below as the “top side”, is made adhesive.
  • the roll of material to be packaged is then rotated with the aid of the support rollers.
  • the packaging web reaches the gap between the roll and the support roller, it is glued there to the outer circumference of the material web roll.
  • the material web roll takes the packaging web with it.
  • the packaging web is separated from its supply roll with the help of the knock-off device.
  • the roll of material web is rotated further until the severed end of the packaging web is also wound up. At least the end of the packaging line must also be made adhesive so that the end of the packaging line also adheres to the circumference of the roll.
  • the adhesive must be applied at the beginning and at the end of the packaging web in order to ensure a durable wrapping of the material web roll.
  • a glue or adhesive is usually applied to make the surface of the packaging web sticky. Glue nozzles or rollers are used for this.
  • This so-called glue section is structurally relatively complex and correspondingly expensive. It requires a high level of maintenance because the glue can harden easily when the machine is at a standstill. In addition, the glue section continues to be a potential source of contamination. If the glue dispensing is not set precisely enough, it leads to unsatisfactory packaging results with too little glue dispensing or to contamination of the material web roll to be packaged by swelling glue if the glue dispensing is too large. Too much glue or adhesive can in particular lead to soiling of the end face of the web of material to be packaged, which in turn leads to individual layers of the web of material from sticking together.
  • this type of adhesive mediation requires very careful monitoring of the packaging process, so that overheating does not occur when the packaging web is at a standstill, which leads to ignition of the adhesive layer and the packaging web.
  • the heating of the packaging web in the material web roll to be packaged leads to a corresponding heating of the outer layers with a corresponding shift in temperature and humidity.
  • GB-A-16 008 discloses the use of rubberized tapes to wrap a roll of oilskin, i.e. the use of adhesive tapes to hold the roll together. These tapes are moistened to make them sticky. They are usually only a few centimeters wide.
  • GB-A-761 741 describes the use of tape rolls to hold a rolled-up newspaper, magazine or the like tightly together.
  • glue can be activated with water.
  • DE-B-12 75 440 describes the application of end covers to the end face of a roll, the end covers being provided with adhesive and the application device having a water spray device.
  • US-A-19 89 183 shows an edge protector for rolls which is glued to the edges of a roll.
  • the edge protector consists of two parts, namely a front cover with radially protruding tabs that are folded in on the circumference of the roll to be protected, and secondly a strip that is glued to the periphery, the strip having tabs that protrude to the side be glued to the front cover.
  • An adhesive is also used here.
  • DE-A-26 31 268 shows an adhesive, an adhesive tape and a production method therefor, the adhesive being activatable with the aid of water.
  • the invention has for its object to provide a packaging of a roll of material web that can be attached relatively safely, can be disposed of easily and requires little maintenance of the adhesive transfer device.
  • This object is achieved in a method of the type mentioned at the outset in that a packaging web coated at least on one side with a water-soluble adhesive is used and the adhesive is wetted before application to the web of material web.
  • the "glue section”, ie the adhesive transfer device, can also be designed correspondingly simply. As a rule, water does not lead to contamination or constipation. The maintenance effort is correspondingly low.
  • the water makes the adhesive sticky, a phenomenon that is known, for example, from the back of stamps. If too much water is accidentally applied, this can run off the packaging line without causing further contamination.
  • the use of water as a wetting agent is harmless. There is no risk that one An operator on a hot machine part still hurts a fire if the packaging process is interrupted.
  • the water-soluble adhesive can be easily washed out during recycling of the packaging web, that is to say it can be separated from the packaging web in such a way that material recycling of the material of the packaging web is possible.
  • a water-soluble cold glue is preferably used as the adhesive.
  • This cold glue can be processed at ambient temperature, i.e. the liquid used for wetting does not even have to be tempered in order to achieve the necessary adhesion. This further simplifies the implementation of the method.
  • the cold glue is preferably a product of animal origin based on gelatin or a product of vegetable origin based on dextrin. Both types of cold glue can be disposed of biologically, i.e. with the help of microorganisms, so that the disposal of the packaging is further simplified.
  • Water is advantageously sprayed onto the adhesive for wetting.
  • the spraying of a material web is a familiar process, particularly in paper factories, because here the paper webs are often supplied with moisture in this way in the production process in order to set a certain moisture profile. The operators can usually draw on experience from other areas.
  • the wetting can be controlled relatively well by spraying. Overall, it can be ensured that no more moisture gets onto the packaging web than with the conventional application of liquid glue.
  • the packaging web is guided through a roller applicator for wetting.
  • a roller applicator for wetting.
  • This is particularly advantageous for the wetting of the end of the packaging web, because one can reliably wetting this end here without running the risk of passing the wetting liquid past the packaging web.
  • simple wetting of the packaging web can be achieved, so that the entire surface of the packaging web is made sticky. This leads to very stable packaging, in which the individual layers of the packaging web stick together.
  • the wetting in the longitudinal and / or transverse direction of the packaging web is preferably limited to predetermined areas.
  • This cutout can optionally also be limited to the first or the first turns of the packaging web.
  • the object is achieved in a device of the type mentioned at the outset in that at least one packaging web coated with a water-soluble adhesive is accommodated in the unwinding station and in that the adhesive-imparting device is designed as a water application device.
  • the production of an adhesive surface is divided into two process steps.
  • the packaging web is coated with a water-soluble adhesive.
  • This adhesive does not stick as long as it is dry. Only when it is wetted by a liquid does it and thus the top of the packaging web become sticky.
  • the coating of a packaging web can be carried out elsewhere, for example in the manufacture of the packaging web, so that contamination of the packaging device by adhesive is practically impossible.
  • the application of water can be easily implemented. A water application device usually requires little maintenance. It can also be of relatively simple design.
  • the adhesive application device has a water spray device.
  • a water spray device expels water through one or more nozzles. This creates a mist, which is deposited on the surface of the packaging web.
  • larger droplets can deposit directly on the surface of the packaging web, which are then distributed as they run into the gap between the material web roll and the support roller.
  • the liquid application can be controlled relatively precisely by a water spray device.
  • the water spray device generates a spray jet which is adjustable in width.
  • this allows the liquid application to be adjusted to the width of the packaging web, so that when using narrow packaging webs for correspondingly narrow rolls of material web, too much liquid does not pass the packaging web.
  • you can With such a water spray device create an adhesive pattern on the surface of the packaging web, which, for example, only makes a central area of the packaging web sticky at the beginning of the packaging web, thus leaving out the edges, in order to prevent the packaging web from sticking to the end faces of the web of material to be packaged while the subsequent turns of the packaging web over its entire width can be made sticky in order to bring about a reliable adhesion of the packaging web to lower-lying windings.
  • the water spray device is divided over the width of the packaging web into several sections, the water supply of which can be controlled separately.
  • the width control is done in stages. However, this is usually sufficient to produce the desired stickiness pattern on the top of the packaging web.
  • the adhesive application device can have a roller applicator.
  • a roller applicator water can be transferred very evenly to the top of the packaging line.
  • the design and maintenance effort is similar to or even lower than that of a spray device.
  • a roller applicator should be used in particular if large-area water application is to be carried out with little effort.
  • a roller applicator works particularly well in "end gluing", ie when the end of the packaging web is made sticky, because it moistens the packaging web to the end.
  • the roller applicator is preferably arranged behind the water spray device in the direction of movement of the packaging web and has a controlled pressure roller.
  • the beginning of the packaging web is moistened by the water spray device and thus made sticky, so that the beginning reliably adheres to the roll of material web to be packaged.
  • the controlled pressure roller can bring the top of the packaging web to the roller applicator to ensure fluid transfer to the top of the packaging web.
  • the water spray device can then be switched off because the roller applicator is responsible for moistening the top of the packaging web.
  • a device 1 for packaging a roll of material web 2 has a winding station 3 with two support rollers 4, 5, one of which is driven by a motor 6, and an unwind station 7.
  • a plurality of supply rolls 8, 9, 10 of different widths for packaging webs 11 are arranged in the unwinding station 7. Of course, there may be more than the three supply rolls shown.
  • a preferential device 12, a knock-off device 13 and an adhesive conveying device 14 are arranged between the unwinding station 7 and the winding station 3.
  • the packaging web 11 is unwound from one of the supply rolls 8, 9, 10 according to the desired width and advanced over a transport table 15 until it enters a gap 16 between the material web roll 2 and the support roller 4.
  • the adhesive transfer device 14 comes into action and makes the top 18 of the packaging web 11, i.e. the side facing the web roll 2 is sticky.
  • the material web roll 2 is set in rotation by the motor-driven support roller 5. As soon as the packaging web 11 enters the gap 16, it adheres to the material web roll 2 and is carried along by it.
  • the knock-off device 13 separates the packaging web 11 from the supply roll 8, 9, 10.
  • the material web roll 2 is rotated further and completely winds up the severed end of the material web 11 on itself.
  • a protrusion of the packaging web 11 is folded onto the end face of the material web roll 2 in a known manner using a star wheel 17.
  • the packaging web 11 is coated on its top 18 with a water-soluble cold glue.
  • This cold glue can be, for example, an animal product based on gelatin or a vegetable product based on dextrin. As long as the coating 19 is dry, it is not sticky. It only becomes sticky when water is added. This effect is known, for example, from the back of normal stamps.
  • the adhesive-imparting device For wetting, i.e. for supplying moisture, the adhesive-imparting device has a water spray device 20 and a roller applicator 21 which is arranged in the direction of movement of the packaging web 11 behind the water spray device 20, i.e. between the water spray device 20 and the winding station 3.
  • the water spray device 20 is supplied with water from a storage vessel 22 via a pump 23.
  • the pump feeds into a distribution line 24, from which branch lines 25 lead to individual sections 26, into which the water spray device 20 is divided in the transverse direction.
  • Each branch line is provided with its own valve 27.
  • the valves 27 of the individual sections 26 can be controlled separately.
  • Each section 26 is assigned a number of spray nozzles 28 which atomize the escaping water and bring it to the coating 19 on the upper side 18 of the packaging web 11. Where water hits the top 18 of the packaging web 11, the top becomes sticky.
  • the arrangement shown in FIG. 3 can also be used, in which the reservoir 22 'can be pressurized via a pump 23' for example by supplying water or compressed air.
  • the storage vessel 22 ' is then connected directly to the line 24.
  • the roller application device 21 has a storage vessel 29 into which a transfer roller 30 is immersed.
  • the transfer roller in turn rests on a driven application roller 31 and supplies the application roller 31 with moisture from the storage vessel 29.
  • a pressure roller 33 is fastened to a swivel arm 32, which is pivoted from the rest position shown with solid lines into a position shown with dashed lines can, in which it presses the packaging web with its top 18 against the application roller 31. In this state, the application roller 31 transfers moisture to the upper side 18 of the material web 11 and thereby makes the coating 19 sticky.
  • the adhesive transfer device 14 works as follows: as soon as the packaging web is advanced on the transport table 15, the water spray device 20 is activated. This is arranged above the transport table 15 and sprays water onto the top 18 of the packaging web 11.
  • the spray device 20 can also have a smaller width than the packaging web 11. Basically, it is only necessary to create an adhesive area with which the packaging web 11 adheres to the material web roll 2.
  • the swivel arm 32 pivots upward.
  • the pressure roller 33 now presses the packaging web 11 against the application roller 31, whereby the packaging web 11 wets its entire width on its upper side 18 becomes.
  • the water spray device 20 can then be switched off because the complete application of moisture is now taken over by the roller application unit 21.
  • the upper side 18 of the packaging web 11 is completely wetted without moisture passing through the knock-off device 13 after the end of the packaging web 11 has been severed and reaching the transport table 15.
