Definitions

  • the invention relates to a web treatment device with a first web insertion device that runs along a first path and a first rope arrangement and a second web insertion device, which runs along a second railway path and has a second cable arrangement.
  • the invention is based on the treatment of a Paper web described. But it is the same Way also applicable to other material webs.
  • a paper web producer sometimes wants different ones Can produce products for which one share part of a production line would like, but part of the production line must for a paper web to be traversed while for a different type of paper web or not on others would have to be run through.
  • a paper web either so that it runs through a calender, or in other ways to bypass the calender. In practice, this was implemented in such a way that both at the right end (related to the axial direction of the Rolling) the calender a rope arrangement is arranged as well as at the left end.
  • the invention has for its object in the leadership a path through the treatment device to have greater flexibility.
  • This task is the treatment device type mentioned solved in that both rope arrangements on the same side of the web treatment device are arranged, the two pathways have at least one common section that Rope arrangements in this section transverse to the direction of web travel are arranged next to each other and across the Direction of web running further inside rope arrangement at least in part of the section from an area is shiftable out, which is transverse to the web running direction is located next to the section.
  • the first train path is the second one Path only in part of the path treatment device different, another part of the two Path paths are identical. For example, this applies to a section behind the actual treatment line to where the web of material regardless whether they have been treated in the treatment device is or not, to a downstream processing station should be performed.
  • the two rope arrangements arranged side by side it could be that the inner rope arrangement the strip the web of material through the treatment device has been guided axially inward on its way (related to an axial direction of guide rollers). To avoid this strip on the hang each axially inner cable arrangement remains, this rope arrangement is simply moved away, so removed from the area where they are for the strip could be an obstacle.
  • the cable arrangements preferably run in the part the section above at least one roller, and the inner rope arrangement can be raised. So you wear account for the fact that the cable assemblies the insertion strip usually only in a relatively narrow Capture area. The areas beyond of the lead strip hang under the effect of the Gravity down. This in turn leads to the fact that the insertion strip under the axially further inside Rope arrangement can be pulled through easily can without being hindered by this rope arrangement. Only in areas where the strip has a Guide or support roller must be pulled, the axially inner rope arrangement lead to problems, because the strip then hangs on this rope arrangement remains. If you look at the shifting of the rope arrangement limited these areas, then you have the necessary ones Measures taken to prevent disability. Basically, no further measures are required.
  • a support element arrangement preferably engages under the liftable rope arrangement and is at least around Height of the support element arrangement can be raised. So you can Support elements, such as fingers or hooks, under the cable arrangement drive the cable arrangement and the cable arrangement then lift. For a collision of the lead strip to prevent the paper web with the support elements, the support elements must of course be raised so far be that a sufficient below the support elements Free space for the movement of the insertion strip is available.
  • the support element arrangement is cylindrical Has support elements.
  • the cylindrical Carrier elements have at least the rope arrangement on them supporting surface a rounded Shape. This minimizes the risk that the Support elements have a notch effect on the rope arrangement exercise.
  • the support elements are preferably rotatably mounted. Due to a rotatable bearing length changes the rope arrangement, which is in the movement of the support elements result in being caught without a Slip or friction between the support elements and the rope arrangement results. The load on the rope arrangement is kept small. The storage of the However, support elements do not have to be at full insertion speed be designed. If the rope arrangement is raised, then it is out of function and can accordingly stand still.
  • the first rope arrangement preferably forms at the beginning of the first path, a first rope shear and the second rope arrangement forms at the beginning of the second Path a second rope shear, each rope shear is designed to be portable. You create on this way, so to speak, a kind of "switch" with which to choose the path through which the insertion strip can be made to be led.
  • the insertion strip is through led the railway path, whose rope scissors are in the area where the train arrives. In this way is also with a single insertion strip on one Side of the web great freedom of choice given the path of the railroad without the need for major modifications are.
  • Each cable shear is preferably from a takeover position movable into a waiting position, the takeover positions are the same for both rope cutters and there is a rope cutter in the waiting position, while the other rope cutter is in the takeover position located.
  • the waiting positions are designed so that the insertion strip is not detected can be. Because the waiting position and transfer position the two rope scissors against each other, so to speak are "locked", the control is in the selection. the pathways simplified.
  • the cable shears are fixed on a common support, the Carrier is relocatable. This is a particularly simple one Designing to ensure that only ever a rope cutter can be "active". If a rope cutter is moved to the takeover position, the other Rope cutters are automatically moved into the waiting position.
  • the carrier has a positioning drive having.
  • a positioning drive is in the Location, the carrier on the frame of the treatment device to be positioned relatively exactly so that the insertion strip the material web with great reliability in the correct orientation is guided to the rope cutter.
  • the paper web 2 is passed through nips 6, 7 which are formed between rollers 8, 9, 10.
  • the rollers 8-10 are stored in a stand 11 of the calender 1.
  • To guide the paper web 2 along the first path 4 several guide rollers 12-18 are provided.
  • Another treatment device is located at the end of the path 4 19, for example a reel.
  • the paper web 2 along the second web path 5 is then passed past the nips 6, 7. Technically speaking, it bypasses the calender 1. Of course, it must also pass through calender 1.
  • the second path 5 has guide rollers 20, 21, 15-18 on, i.e. between the guide roller 15 and the treatment device 19 there is a section 22 which is common to both pathways. Part 23 of the section 22 runs above guide rollers 16, 17. We will come back to this later.
  • each path 4, 5 a rope assembly 24, 25, each rope assembly 24, 25 by a pair of ropes 26, 27 for the first Rope arrangement or 28, 29 for the second rope arrangement 25 is formed.
  • the rope pair 26, 27 of the first rope arrangement 24 is guided along the first path 4.
  • the second pair of cables 28, 29 of the second cable arrangement 25 is guided along the second path 5.
  • the pair of cables 26, 27 forms at the beginning of the first path 4 a first cable shear 30 in which the two Ropes 26, 27 converge and the converging ones Paper web 2, which is narrow for this purpose Stripes (known, but not shown) cut is capture.
  • a transport device 31 provided, in the simplest case as Is formed sliding surface, but also air nozzles or can even have a conveyor belt.
  • the second cable arrangement 25 also has cable shears 32 in which the ropes 28, 29 converge, and, as can be seen from FIGS. 3 and 4, the tapering Paper web 2 can capture.
  • Both rope cutters 30, 32 are on a common one Carrier 33 arranged in the direction of a double arrow 34 is displaceable on the stand 11. With the relocation the carrier 33 is also shifted two rope shears 30, 32. So the rope shears are changeable relative to the incoming paper web 2 educated.
  • both cable shears 30, 32 on the common Carriers 33 are arranged, they can only be used together be moved. So it is always ensured that only one rope cutter 30 or 32 is in a position in which the incoming Paper web 2 can capture. This is the so-called "Transfer position.” 1 and 2 show that the cable cutter 30 is in the takeover position. 3 and 4 it can be seen that the cable cutter 32 is in the takeover position. In 1 and 2, the cable shear 32 is in one Waiting position in which they normally go from paper web 2 is not available. 3 and 4 is located the rope cutter is in the waiting position, i.e. it cannot be reached by the paper web 2.
  • a positioning drive is used to displace the carrier 33 35 provided with which the position of the carrier 33 and thus also the positions of the rope cutters 30, 32 on the stand 11 can be set very precisely.
  • the carrier 33 is lowered so that the first Cable shear 30 is in the takeover position.
  • the incoming paper web 2 is supported by the Transport device 31, the cable shear 30 fed and thus automatically enters the first path 4.
  • the carrier 33 is raised, so that the rope cutter 32 in the takeover position located.
  • the paper web is through the Ropes 28, 29 inserted into the path 5.
  • the ropes 26-29 are not shown in FIG Way from the ends of the two pathways 4, 5 that don't necessarily have to match, back again the respective beginnings. To avoid a collision avoid the ropes 26, 27 on the one hand and 28, 29 on the other hand, offset from each other in the direction of web travel, as can be seen from FIGS. 1 to 4.
  • a guide roller 41 on the guide roller 14, which is only one Rope assembly 24 must take, however, only points a groove on.
  • the two rope arrangements 24, 25 transversely to the direction 42 of the paper web 2 side by side arranged.
  • the rope arrangement 24 of the first running path 4 is located axially (based on the Direction of guide rollers 15-18) further inward than that Cable arrangement 25 of the second path. So if the Strip of paper web 2, which is passed through the calender 1 should be, with the help of the cable assembly 24 along of the first path 4 is then the Procedure normal, i.e. the strip is in the Cable shears 30 are grasped with the aid of the cable arrangement 24 passed through the calender 1 and when it is on the other Has arrived at the end and a train can be exerted on him can, the strip is transverse to the direction 42 drawn inside into the actual processing zone. In 5, it is pulled to the left.
  • the strip is along the second path of the path 5 is pulled, so with the help of the rope arrangement 25, the following effect occurs: one must assume that the strip where it is not from the rope arrangement 25 is taken under the action of gravity something hangs down. Has in the area of the guide roller 15 this does not cause any problems. The one hanging down inner edge of the strip can be under the rope arrangement 25 of the first path passed without problems become. This also applies if the cable arrangement 24 stands, i.e. does not move at web speed.
  • the support elements 43, 44 are cylindrical, at least on their supporting the cable arrangement 24 Surface. This prevents the cable arrangement 24 is buckled by the support elements 43, 44.
  • the Support elements 43, 44 can also be rotatable his. Here, however, storage is reduced Requirements because the cable arrangement 24 is not normally moved when raised.
  • the rotatable mounting of the support elements 43, 44 serves to small changes in length caused by lifting of the first cable arrangement 24 result to compensate can.
  • both rope arrangements have 24, 25 means up to that by shifting the cable shears 30, 32 due to length changes take.
  • the web guide is shown in a calender.
  • a the corresponding web guidance is also with other treatment devices applicable for railways, for example with coating machines, dryers or dampers or similar.
