Definitions
- the invention relates to a device for packaging a material web roll with a packaging web a packaging web donor who the packaging web with an acute angle of their transverse direction to the axial direction the web of material and the one Has adhesive application station.
- Such a device is from the post-published DE 195 35 746 known.
- the web rolls to be packaged have a considerable amount Size. Their diameter is usually in the range from 500 to 2500 mm.
- the roll width can 500 to 3800 mm or even larger.
- Such web rolls arise, for example in paper or textile production.
- the packaging line offers here on the one hand mechanical protection against damage. On the other hand it should also consider the influence of environmental parameters, like humidity, keep it small.
- the packaging web dispenser aligns to the roll of material so that when Wrapping results in a pure packaging, but at an angle, then when winding the Packing web around the material web roll a helical Packaging so that you can with a single Packaging web width practically all widths of the material web rolls can operate.
- the invention has for its object the packaging times to keep short.
- This task is the beginning of a device mentioned type solved in that the adhesive application station a first adhesive application device as a company gluing device and a second adhesive application device as a final gluing device having.
- winding speeds i.e. the speed at which the web roll is rotated after you have the packaging web on it Has brought and attached plant.
- the increase in Only then does winding speed have any significant value Influence if at the same time the acceleration times be kept short, i.e. the material web roll with the adhesive packaging web as strong as possible is accelerated. Because the packaging web on the material web roll is stuck, this has the consequence that the adhesive connection is heavily stressed. This strain occurs especially at the beginning of the winding process on if the packaging line is not yet through other measures held on the web of material is, for example, the partial coverage by a subsequent packaging web layer. Also says if the wrapping process, i.e.
- the packaging process in a short time Time should take place, only a very short time for Available within which the adhesive bond is made can be.
- the packaging web dispenser is arranged on the side next to the roll of material web, which offers advantages in terms of manageability, then the packaging web is between the web of material and a carrier roller on which the Material web roll rests and from which it is rotated.
- the packaging web must consist of the material web roll and the support roller but then with a firmness or adhesive force adhere to the roll of material that is sufficient to prevent loosening.
- the second Carrier roller pressed the packaging web again will. At the latest after leaving the second nip between the web roll and the support roller but "hold" the adhesive connection.
- this problem is solved in that two adhesive application stations are provided.
- One of those is designed as an "operating gluing device". It is used to apply glue for the Formation and gluing of the packaging along the axial length of the web roll necessary and sufficient is. It can be a relative trade cheap glue, for example water glass.
- this adhesive needs a certain amount Time to reach the necessary adhesive strength.
- the So gluing equipment would not be sufficient order at the beginning of the packaging when the packaging line be attached to the web roll to ensure the necessary connection. This is then the final gluing device is provided. This gives the packaging line a fast-acting Adhesive application. Adhesives can certainly do this are used, which have other disadvantages, such as higher costs or greater risk of pollution.
- the operating gluing device at least two in essentially parallel to the edge of the packaging line Adhesive beads produced.
- Adhesive bead here is an approximately linear adhesive application can be understood, but which may also break through can be. With such adhesive beads ensures that the packaging line is continuously on Scope of the web of material or if the overlap Packing web on a previously applied layer of Packaging web is glued. You achieve it one fixed over the axial length of the web roll connected packaging, its protective function definitely corresponds to a packaging that with a correspondingly wide packaging line is. However, the result is helical running packaging optically a much better Impression with longer web rolls. Each the wider the packaging lines become, the more difficult is to fold them to the circumference of the web of material to create.
- the glue delivery from the company gluing device is advantageous depending on the speed controllable on the packaging line.
- high packaging speeds 300 m / min, for example, if one high winding speeds and correspondingly short Acceleration times used. But this leads to a problem with glue application.
- you apply the glue i.e. the amount of adhesive dispensed per unit of time that adapts to the high speeds, to be reliable over the length of the material web roll
- the adhesive application to the low speeds adjust at the beginning and at the end, then the amount of adhesive is sufficient may not be out to the packaging over the axial length of the material web roll with the to produce the desired quality.
- the problem can be circumvented by having the glue release controls depending on the speed. At the beginning and at the end the packaging if the web of material rolls with rotates at a lower speed and therefore the Speed of the packaging line is low little glue applied. If the speed is high, more glue is applied. You can on this way ensure that the adhesive application per Unit length of the packaging web essentially constant remains. Smaller fluctuations are sometimes unavoidable. But it is sufficient if the adhesive application within a range of approximately ⁇ 15% around a predetermined one Value remains, regardless of the speed.
- the operating gluing device is preferably clocked and dispenses glue in the form of drops. This makes it particularly easy to dispense the adhesive Taxes.
- the adhesive comes with a certain Introduced pressure from an adhesive supply. In the Plant gluing device becomes an output opening but only released temporarily. During this time then leak adhesive. With a clocking, with the for example, the gluing device periodically can be opened, the adhesive delivery is determined then according to the duty cycle, i.e. the relationship the opening time to the period. Such Clocking requires far less effort than the exact setting of a throttle that the glue escapes could also control.
- the time interval and / or the size of the drops depending changeable by the speed of the packaging line is.
- there is also one A combination of both possibilities is conceivable. You just have to ensure that the adhesive application per unit length the packaging line in the desired destination corridor remains.
- the distance between the drops of adhesive is preferably at the packaging web at least approximately constant. Of the Distance can also go to zero. Achieved by this one very much over the length of the packaging line uniform formation of the glue beads. Usually you will accept a small distance between the drops, because the glue when putting on the packaging web anyway a little bit broad on the web of material becomes. Adjacent drops of adhesive can then form here come into contact with each other. It can still be desired to use along the glue bead areas strong and areas with less strong connecting forces to have, as for example through the arrangement in a row the drop can be effected. This makes it easier to unpack the web of material.
- the glue beads are the edges of the Packaging track arranged adjacent.
- the Glued edges Damage to the packaging Objects that are between individual packaging layers pushing is largely impossible made. The penetration of moisture will also practically immediately next to the edges of the packaging web stopped.
- the final gluing device preferably effects one flat adhesive application. Generate the glue beads a largely linear adhesive application, so that for the holding force only a correspondingly small one Area is available. If you have one choose larger adhesive area, then you can under otherwise unchanged conditions also a higher adhesive force to reach. Even if the specific adhesive force, i.e. the adhesive force per unit area, in one application is not larger than that of the glue bead the chance is much greater that the adhesive connection holds with the roll of material so far that the Packaging web can be wound up on the roll.
- the final gluing device is an adhesive spray device having.
- an adhesive spray device is not just a flat adhesive application generated.
- the sprayed adhesive usually has also a much higher initial adhesive strength than one normal glue bead. This may be because that the glue when it hits the packaging web has been sprayed on, a lesser Contains water.
- the spraying of glue is known per se. But it usually leads to one very fast contamination of the adhesive application device and its surroundings, so that you have an adhesive spray device not happy to use.
- the necessary Maintenance work reduces economy. If you only use the adhesive spray device at the beginning and possibly at the end of the packaging line must use, then their operating time becomes short held. Accordingly, the pollution remains, when using an adhesive sprayer results. A cleaning is necessary. However, this can be done at longer intervals.
- the adhesive spray device is preferably applied essentially the width of the packaging web Adhesive. You can use it to apply the adhesive along Limit the length to relatively short areas. Around One will keep the pollution low a certain distance when spraying the adhesive Adhere to the edges of the packaging line. Through a short-term, wide adhesive spraying can, however a high initial strength of the adhesive connection achieve with low pollution of the device.
- Fig. 1 shows a device 1 for packaging a Material web roll 2 with a packaging web 3.
- Die Material web roll 2 is here on two support rollers 4, 5 stored, of which the support roller 5 with the help of a Drive is rotatable. When the support roller 5 rotated material roll 2 also rotates.
- 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 3. 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 turns when turning Roll of material 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 0.35 up to 0.75 m. To make a packaging are therefore a plurality of revolutions of the web roll 2 necessary. It is obvious that there are some for this Time needed. So the packaging time can definitely be accept higher values.
- 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 2nd
- 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 15 on that as a company gluing device is referred to, and a second adhesive application device 16, the final gluing device is called because it covers the areas of Packaging web 3 provided with adhesive to the axial ends 17, 18 of the material web roll 2 positioned will.
- the operating gluing device 15 stands over a Line 19 and a pump 20 with a storage vessel 21 in connection.
- the pump 20 takes out glue from the storage vessel 21 and conveys it under pressure through line 19.
- the glueing device 15 here has valves 22, which are operated by a control device 23 can be opened and closed. Accordingly, the valves 22 admit the adhesive from drop 24.
- the control device 23 stands also in connection with the drive 6 of the support roller 5.
- the valves 22 are controlled so that the adhesive application is timed depending on the speed of the packaging line 3 varies. More specifically, it is controlled that the adhesive application per unit length of Packaging path 3 is constant or at least in one predetermined target corridor remains. This can be done, for example thereby achieve that the control device 23 clocks the valves 22, i.e. in periodically consecutive Times opens and after each Opening closes again, with the opening time in proportion to the entire period length, i.e. the so-called Duty cycle, depending on the speed the packaging web 3 can be varied. One can of course the period length also vary and that Leave the duty cycle the same or vary both. Accordingly, at the start of winding, when the web of material roll 2 rotates slowly and accordingly the packaging web only a lower speed has released less adhesive than in further course of winding where the web of material roll 2 is rotated at a higher speed.
- 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 second adhesive application device is on a line 26 and a pump 27 with a storage vessel 28 in connection. It has spray nozzles 29, which also have a valve 30 is connected upstream.
- valve 30 is opened, for which purpose also the control device 23 in action occurs, then a spray jet 31 is formed through which Adhesive to areas 32 on the top 14 of the packaging web 3 arrives.
- 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 areas 32 In longitudinal or 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. Accordingly, the final gluing device 16 even be operated for a very short time, so that the pollution of the environment remains small.
- the area Basically, 32 only has to have a length that corresponds to that Distance between the two support rollers 4, 5 corresponds. In particular In some cases, the area 32 can be even shorter be.
- both the end gluing device 16 put into operation as well as the operating gluing device 15, the latter a relatively small amount of adhesive per Time.
- the spray order from the final gluing unit 16 on (or it begins shortly before the end of the packaging line 3) and only the adhesive application remains in the form of glue beads 25 by the company gluing device 15 is generated. This is sufficient because the glue caterpillars after a certain Time the desired fixed connection of the individual Lay the packaging web 3 with each other or with the Material web roll 2 guaranteed.
