Description

The proposed invention relates to the technical Field of winding web-like material made of paper, foil, plastic, fabric, textiles or the like at least one role with at least one forming Roll rotatable on its outer periphery touching first roller.

Facilities of the type mentioned are, for example used relatively wide webs from said Material using at least one slitter cut into narrow strips and these Then wind up strips into smaller rolls. Such facilities were, for example, by the US-A 3 841 578, EP-A 0 118 384 or DE-U 83 17 214 known, EP-A-0 118 384 a device with the features of The preamble of claim 1 is disclosed. However, the nature of such machines becomes clear that the unwinding role after a longer Service life of the facility is exhausted and by a new one needs to be replaced. Achieved in an analogous manner the at least one new role to be rewound their final shape at a certain operating time, generally their final desired diameter, which is why it becomes necessary to have this role or roles take out of the machine and with the subsequent winding of at least one new roll to start. In addition, they must be used to slice the original wide web used knives such as Circular knife after a certain operating time new sharp knives are exchanged. All of these operations are with conversion work, maintenance measures or operating work inevitably connected, which is why the machine to perform such work also inevitably must be stopped. Stopping the machine however means at the same time a corresponding one Failure of the production with the machine can be achieved. In earlier times, these took Conversion work takes a lot of time, so that machine equipment in question often stand still for longer than they were in production. To the present description of the invention Keeping it as short as possible is therefore another Support and / or supplement to the present description to the prior art, in particular the referred to above.

The task is therefore to determine the downtimes of the in The machine in question and the so-called Setup times required to change the machine from one Production process to another are required to diminish. This task is added using the Expectations solved. Other features and advantages result from the following description of an embodiment. The individual characteristics of the Embodiment can each individually or individually any combination with the help of Realized specialist knowledge of further embodiments of the invention be. Using one in the attached figures schematically illustrated explanatory of the inventive concept and not a limiting embodiment the proposed solution will now be explained in more detail. The embodiment can also in different Modified or by further embodiments be supplemented without the basic idea staked out by the subject matter of claim 1 Leave frame. In the figures are in the present Connection not essential, sufficient for the expert known machine parts because of a clearer Not shown. The figures show rather only those parts that are needed for further explanation of the proposed solution and its advantages are. Based on the existing suggestions it is therefore no longer necessary for the person skilled in the art, inventive to take action to include his Expertise to carry out other applications, other areas of application to develop or other embodiments to develop if this proves to be beneficial or even prove to be necessary from a design point of view should.

A web-like material 1, such as a web made of paper, foil, fabric, textiles, plastic, metal od. Like. runs in the direction of arrow 2 from a corresponding Unroll coming from the one in question machine setup too. On their way to the so-called The web-like material 1 runs through a winding point Longitudinal cutting device 3. Here it becomes original relatively wide web-like material 1 in its Running direction, d. H. in the direction of arrow 2 in several cut narrower stripes. Usually everyone narrower strips wound into a roll. It is however also possible with the longitudinal cutting device 3, So-called. Edge strips from the sheet-like material 1 or cut off so that the edge of the web-like Materials 1 for the subsequent winding process becomes sufficiently straight and clean. However, it is possible both the web-like material 1 in narrower strips to cut as well as so-called edge strips cut out the web. These margins can either also wound up in rolls or one Waste device are supplied. In this way it is created at least one strip leading to a later one Roll is wound. However, several can also be used Cut strips out of the web-like material 1 be each a role in itself be wound up. The so-called winding station contains one first roller 4, which by means of its size the size the at least one resulting from the winding process Roll 5 touched during the winding process. The first Roller 4 can, for example, a support roller of a so-called. Carrier roller roller or a backup roller so-called back-up roller winder, depending on the type of winding machines, the first roller 4 is installed. The first roller 4 is rotatable in a corresponding frame stored and can, depending on your needs, in size or in driven their center with the help of a suitable device become. In Fig. 1 is a so-called carrier roller winder for example, which shows a fourth roller 6 is assigned. The fourth roller 6 can also be in shape a support roller. It is also in the corresponding one Frame rotatably mounted and can be made as desired be driven. Between the two rollers 4 and 6 arises thus a winding point 7 at which the new roll 5 can arise from the winding process. The illustrated The device also contains a device for removal the wound roll or rolls 5. These The device essentially comprises a swivel body 8. The swivel body 8 is by means of a joint 9 or several such joints in one or more bearings 10 in the machine frame or one connected to it Part pivoted. With the help of another warehouse 11 is a pressure medium cylinder 12 with the machine frame connected, the pressure cylinder 12 on the other hand with the aid of a bearing 13 on the swivel body 8 is attached. Several such cylinders and bearings, that in the viewing direction of FIG. 1, for example can be arranged one behind the other, if necessary be provided. If pressure medium in a corresponding manner is inserted into the pressure cylinder 12, the Swivel body 8 pivoted in the direction of arrow 14 become. He can, for example, from a standby position are pivoted such that that in FIG right end 15 of the swivel body 8 in the immediate vicinity reaches the outer circumference of the first roller 4. Around To avoid damage to the right End 15, for example, at least one roller 16 rotatable be stored so that it becomes possible to pivot the body 8 to pivot such that its right end 15 on the outer circumference of the first roller 4 rests. It is however, the roller 16 by a cushion or the like. to replace, so that there is about excessive pivoting of the swivel body 8 is not about injuries or damage of the machine parts involved comes. On the other hand can the swivel body 8 with the help of the pressure medium cylinder 12 are pivoted in this way, in FIG. 1 for example to the left, that one inserted in it already finished roll 5 'to the left of the Swivel body 8 can be conveyed out. To this The role 5 '- or more such roles - one appropriate storage are fed. To do this To enable the upper surface 17 of the swivel body 8 either as a grid or even as a closed one Surface, for example, like a box between two corresponding ones Side parts arranged so that the roller - or the rollers 5 '- by the swivel body 8 is supported enough. For example, the top one Surface 17 of the swivel body 8 with the side parts 18th and 19 firmly connected. Next to it are in the top surface 17 for example windows 20 and 21 incorporated. By the window 20 projects the circumference of the further roller 22 and through the window 21 the circumference of a third roller 23. The rollers 22 and 23 are in corresponding bearings 24 to 27 rotatable in the swivel body 8 or its individual parts stored. In addition, the further roller 22 with a Motor 28 and the third roller 23 with a motor 29 connected so that by excitation of the appropriate motors the further roller 22 and / or the third roller 23 rotated can be. The bearings of the rollers 22 and 23 are chosen such that, as already indicated, the sizes both rollers from the upper surface 17 of the swivel body 8 protrude slightly. That way it will allows at least one pre-wound roll with a corresponding swivel position of the swivel body 8 is supported by the rollers 22 and 23. If so at least one of the motors 28 and 29 driven then it becomes possible to have at least one finished Roll 5 'to rotate at least relatively slowly. In order to it is made possible by an appropriate cutting process transverse to the running direction of the web-like material 1 severed end, which also with glue or a similar acting material can be coated, the web-like Material between the respective roll 5 'and at least pull one of the two rollers 22 and / or 23 through, so that the end on the next lower winding layer the wound roll is pressed on. In this way the respective roll 5 'can be closed, so that in subsequent storage not due to her inherent tensions can spring up. After this the respective roll 5 'has been closed in this way is, the swivel body 8 with the help of the pressure medium cylinder 12 are pivoted such that the respective Roll 5 'conveyed out of the winding machine will be fed to an appropriate tray to be able to.

Instead of rollers 22 and 23, you may be able to, provided this should turn out to be necessary, too individual smaller, also narrower rolls can be used or also appropriately designed smooth fixed As long as it is possible, the respective roll 5 ' to be based on such facilities and while rotating that the cut end of the web-like Materials 1 to the next lower winding layer of the respective role 5 'can be forced. It is not required, the respective role 5 'exclusively to rotate on its circumference. For example it is besides or also additionally conceivable, the respective To drive roller 5 'rotatably in its center, see above that also in this way a rotational movement of the respective Roll 5 'is expected. In addition, the first roller is 4th with the help of bearings 30 and 31 in frame parts 32 and 33 with the help of journals 34 and 35 rotatably mounted. With With the help of a motor 36, the first roller 4 can, if necessary are driven. The fourth roller 6 is by means of Bearings 37 and 38 and journals 39 and 40 also rotatable stored, for example, also in the housing or Frame parts 32 and 33. On the trunnions 39 and 40 are Swivel arms 41 and 42 rotatably mounted. The swivel arms 41 and 42 are connected to a housing 43. The housing 43 is by means of a joint 44 with the pressure medium cylinder 45 connected. This is by means of joint 46 firmly connected to the machine frame. By initiating Pressure medium in the pressure medium cylinder 45 can be the housing 43 in the direction of arrow 47 around the bearing journal 39 and 40 are pivoted. The housing 43 has accordingly Fig. 1 shows a cross section, the shape about of a crescent or, for example, one large Latin C is similar. On the housing 43 there is also a joint 48 and a joint 49. A bracket 50 is pivotally attached to the hinge 49. The carrier 50 has a further joint 51. On the joint 51 and on the joint 48 is a pressure medium cylinder 52 pivotally attached so that by introducing pressure medium in the pressure medium cylinder 52 of the carrier 50 .mu.m the joint 49 can be pivoted. The carrier 50 contains at the same time a bearing 53 for a roll 54 or the like. With the help of the pressure medium cylinder 52 can the carrier 50 is guided against the housing 43 or be removed from it that a gap 55 essentially can be closed or opened. Next to it is the inner surface 56 of housing 43 also substantially crescent-shaped and therefore since they are inside the Housing 43 is also trough-shaped, so that at least one new one in the interior of the resulting depression Winding sleeve 57, a winding shaft or the like can be inserted can, before the housing 43 using the pressure medium cylinder 45 was pivoted. If in the pressure cylinder 45 initiated pressure medium in a corresponding manner was, then the housing 43 pivoted in the direction of Arrow 47, for example, counterclockwise, see above that the roll 54 or its scope on the scope or the sizes of the roll or rolls 5 hit. Further Introduction of pressure medium into the pressure medium cylinder 45 causes the housing to pivot further 43 in the direction of arrow 47, and also in the opposite direction the clockwise direction, so that the roller 5 from the formed by the first roller 4 and fourth roller 6 Carrier roller bed can be lifted out. If more so preparatively the swivel body 8 with the help of the pressure medium cylinder 12 in the direction of arrow 14, namely in Clockwise to an appropriate position had been pivoted, then the roll 5 out of the support roller bed mentioned to the upper Surface 17 of the swivel body 8. You can from there formed by the further roller 22 and the third roller 23 second carrier roller bed can be collected. The Housing 43 and all associated parts form in in its entirety, a device for removing the coiled roll 5.Because the inner surface 56 of the housing 43 has a trough-shaped design, and in it before the process of removal a new winding tube, a new winding shaft or the like can with the ejection of the wound roll 5 from the bed of the large carrier rollers at the same time new winding tube or winding shaft or the like 57 of the winding station 7 are supplied. This happens because over the winding 7 of the pressure medium cylinder 52 accordingly is operated so that the gap 55 is sufficient is large around the winding shaft, winding tube or the like. 57 to let it pass through. With that the new winding tube arrives quasi simultaneously with the ejection of the wound Roll to the winding point, so that a new winding process can be started. The carrier 50 forms together with the joint 49 thus a kind of flap or the like, which compared to the crescent-shaped cross section Housing 43 moved by means of the pressure medium cylinder 52 can be. Instead of such a flap, however, is also a kind of slide conceivable with which the gap 55 each can be opened or closed as needed.

Regarding the first roller 4 and the fourth roller 6 in the direction of arrow 2 and the web-like material 1 upstream, there is the longitudinal cutting device 3. It essentially comprises one in that not shown Machine frame rotatably mounted lower knife 58, which can be driven if necessary. Several of these Lower knives are one behind the other in the direction of view of FIG. 1 arranged, for example in that the lower knife 58 with multiple cutting points or cutting edges is equipped, for example from a so-called Knife rifle exists. Several such cutting points are arranged in series in Fig. 1 and can also over the entire width of the web-like material or whose greatest breadth is sufficient. Works with the lower knife 58 at least one possibly driven upper knife 59 together. Here, too, several upper knives 59 can be seen Fig. 1 may be arranged one behind the other. The upper knife and if necessary, the lower knives can also be seen in the direction of Fig. 1 assume different positions in a row, so that it is possible to have strips of different widths cut out of the web-like material, depending on how wide the reels 5 or 5 'to be wound become. The upper knife or the upper knife 59 is / are each mounted on appropriate slide guides, which allow the respective upper knife 59 to be displaced, thereby from the effective range of the respective cutting edge of the respective lower knife 58 and other Place again. The respective Upper knife 59 moved in the viewing direction on Fig. 1 and at the desired location. The knives, in particular the upper knives 59, are very sharp to use with their Help to create cut edges in the web-like material 1, which allow rolls 5 or 5 'to be wound up perfectly. Since the knives, especially the upper knives 59 are sharp, they must be protected against unwanted touch be because an operator as a result the sharpness of the knives can hurt very easily if the conversion work is carried out. Besides that, can an operator injures himself on the knives, if this while other operations be carried out, exposed unprotected. For this A cover 60 is proposed for this reason the entire width of the web-like material can range or which are divided into individual sections or parts is, so that several similar covers 60 'in the direction of view 1 are arranged one behind the other. Each cover may include at least one hinge 61 which appropriately stored in at least one pedestal 62 is. The bearing block 62 is with the rest of the machine frame, for example from parts of the floor a production hall can exist, firmly connected. The Cover 60 has a cross section that is approximately one corresponds to large Latin Z. The right one sticks out End 63 of the cover 60 at least over the upper knife 59 or both via the upper knife 59 and the lower knife 58. The cover 60 can in the direction of the arrow 64 can be pivoted about the joint 61, for example by hand or by means of appropriate pressure medium cylinders or other similar devices. When the cover 60 opposes the direction of arrow 64 has been pivoted clockwise, then at least an upper knife 59 freely accessible in front of the operator, so that, for example, a blunted upper knife 59 can be exchanged for a sharpened can. In addition, other operations are easy possible. Conversely, if the cover 60 is in the direction of Arrow 64 extreme, d. H. against a stop 65 clockwise has been pivoted, then access is too denied the upper knife or the upper knives 59. At the same time forms the cover, especially its upper one Area 66 an access path for an operator 67, which the upper surface 66, for example with the aid of a Can climb level 68. In this way, about required operations, for example in the Near the winding point 7 are carried out so that the Operator 67 comfortably reached the winding station. The Covers 60 'are therefore essentially parallel the first roller 4 or the roller 5 or its geometric Axes. Since several covers 60 'are arranged one behind the other can be arranged along a straight line, which is arranged in the viewing direction of Fig. 1. The different covers 60 'are similar to each other and arranged in parallel with itself as it 1 behind each other in the direction of view of Fig. 1. The Arrangement of several relatively short the cover 60 forming Partial covers 60 'have the advantage that the operator 67 even when handling one of the top knives 59 and thus opening a partial cover 60 ' of the adjacent partial cover 60 ', if this is closed. Instead of one or more joints and pillow blocks 61/62 can be attached to each partial cover 60 'also rails 69 and 70 can be arranged, which in corresponding counter rails 71 and 72 engage. The counter rails 71 and 72 are with the machine frame or firmly connected to the floor for the machine frame. In this way, a partial cover 60 'cannot pivoted in the direction of arrow 64, but along the rails and counter rails 69 to 72 are moved, to achieve essentially the same goal like when you swiveled it. The rails 69 to 72 are therefore arranged in such a way that its longitudinal extension is perpendicular lies or is substantially perpendicular to the geometric axis of the first roller 4. Next to it is possible, covers 60 or partial covers 60 'too to be placed above the cutting device 3, that they are only loosely placed or in appropriate holders be inserted. However, this has the disadvantage that the covers may not always be correct Location remains, but may not at all or may not be partially present, so that an unwanted Access to sharp knives despite the existence not always completely prevented by covers can be.

On the trunnions 34 and 35 of the first roller 4 are pivotable with the aid of appropriate pressure medium cylinders Holder 73 and 74 stored. Each holder consists of a radially inner part 75 and a radially outer part Part 76. The outer part 76 includes a hinge 77, whereas the inner part 75 contains a joint 78. A pressure medium cylinder is located between the joints 77 and 78 79, which upon initiation of the corresponding Pressure fluid is able to face the outer part 76 the inner part 75 to remove a certain path. To make this possible, is on everyone outer part 76 a tongue 80, which in at least one Rail 81 is guided, which in turn on the inner part 75 is located. Each radially outer part is 76 provided with a holder 82 in which a wire, a narrow knife or any other device attached can be, which allows the web-shaped Material 1 transverse to its direction of rotation indicated by arrow 2 or roughly across, to cut or to separate. In this way and in that the holder 73rd and 74 in pairs and synchronized with each other can be, the possibility is given to the web-like Separate material 1 to finish removing one to allow wound roll 5 or 5 'from the machine. For such a separation process, each holder, for example, the holder 73 in Fig. 1 in an Elfuhrstellung be pivoted. However, there are others Positions possible, for example an entry position or a two o'clock position, depending on the size of the Space is available.

Because the wire / knife with the help of the respective pressure medium cylinder 79 radially can be moved to the first roller 4 is the Given the possibility of the web-like material 1 cut through when at least one is completely wound Roll has assumed position 5 'and material 1 thus between the further roller 22 and the first roller 4 stretched and ready for separation. Each a holder 73 or 74 including those attached thereto Parts are assigned to the end face of the first roller 4. Instead of a wire, a narrow one can also be used band-shaped knife can be used, which in turn either with a straight bevel or with a so-called Serrated edge can be provided.

With the help of the present device, a web-like Material in several strips lengthways, i.e. H. in its Cut direction and wound up into a roll become. Then this role can be done very quickly removed from the winding shaft and a new winding tube or the like. for a subsequent winding process in the Winding point are inserted. The wound roll can especially if they are at the appropriate place with the help a nozzle 83 has been provided with glue or the like in a second given by rollers 22 and 23 Carrier roller bed are sealed to make them final remove from the winder and for example to be able to feed a shelf.

Instead of a nozzle 83 or its effectiveness can essentially support in Fig. 1 essentially above that representing a pivoting device Swivel body 8, in particular above it in Fig. 1st right end 15, that is, on that side of the swivel body 8, which faces away from the first roller 4, a carriage, Sled or the like. 84 may be provided. The carriage, sledge or the like. 84 can be moved along guides 85 and 86 which, in turn, are perpendicular to that caused by the Arrow 2 indicated running direction of the web-like material 1 and arranged substantially parallel to the upper surface 17 are, so that the guides 85 and 86 at least across the entire width of the web-like material 1 reaching at right angles to the web-like material 1 itself are arranged. The carriage 85 is essentially, for example from European patent application 99 732 known per se. One worked into the swivel body 8 Cutting groove 87 complements the device. The cutting groove 87 runs parallel to the guides 85 and 86. With the Guides 85 and 86 can further guides 88 and 89 such be connected that the carriage 84 in Fig. 1 perpendicular can be moved according to arrow 90. To this In this way, the carriage or the like 84 can be lowered as far as necessary be that an adhesive tape located on it or a corresponding glue nozzle, the web-like material 1 can achieve which on the upper surface 17 for reception of adhesive or the like is spread. The said Glue nozzle is attached to the cart or the like. 84. Alternatively for this purpose the carriage or the like 84 can also have a rolling device included, of which an adhesive tape, possibly under Inclusion of a carrier or support tape are deducted can. In addition, the carriage 84 or the like can be a retractor included with which the carrier tape is rewound after the tape has been removed from the carrier tape solved and transferred to the web-like material 1 is. In addition, the carriage or the like 84 can be turned on at the same time Knives that are able to support the web-like To cut material 1 across its direction. The guides 88 and 89 can also be a total Form a cage in which the carriage 84 or the like Senses can be shifted. The cage would have the advantage that when not in use by an appropriate Holding or swiveling device in an ineffective place can be spent, for example in Fig. 1 upwards. This would have the further advantage that the car 84, his Guided tours etc. provide access to the facility in question the operator would not block 67. Appropriate motor drives, controls, safety devices etc. also complement this facility as well as the entire machine in question.

All processes for changing a role can largely automatic, d. H. going on without human intervention. Human assistance is only necessary in a few cases. Likewise, the disconnect process used for starting a new winding process is also required be carried out automatically. Corresponding safety switches, Limit switches, control devices, Control devices and sequence controls complement the proposed facility. Next to it is still for the safety of the operating personnel, if provided the operating personnel may still be required should. This way it is with the measures described possible both individually and in combination, the time required for the changeover of the machine Set up from one production program to another is necessary to reduce, especially the more so several of these features are used. With that the Downtime of the machine and the associated Loss of production as low as possible.

The bearings 24 to 26 are in or on the swivel body 8 attached that the geometrical axis of the respective Roller 22 or 23 substantially parallel to that the first roller 4 come to rest. With that are also Rollers 4, 22 and 23 parallel to and parallel to each other the respective building up by the winding process Role or building roles 5. Parts 43 to 54 result in a total device for ejecting the wound Roll or rolls 5, so to remove the respective Roll 5 from the winding station 7 and thus in total from the proposed machine. The glue strips applied by the glue nozzles or the with the help of the car applied adhesive strips besides be dimensioned such that they can also be attached a new start of the web on a new winding tube or winding shaft can be used.
