Definitions

  • the invention relates to a stripping device for one in a machine for manufacturing or processing a web, in particular paper web insertion strips to be threaded according to the generic term of claim 1, further a method according to Preamble of claim 10.
  • Strip markers and methods of the the type mentioned here are known. You point at least one baffle, with the help of Web or the insertion strip when starting the machine or after one Web demolition is handed over. To the before handover to cut off a web running into a catchment area, are in the swiveling range of a web handover Baffle separators provided, the two that interact, for example Knife edges that have the expiring Cut off the web and allow takeover of it.
  • An exemplary embodiment of the stripping device is preferred, which is characterized by that the separating element is flexible in itself is. Already through the special design of the separating element becomes the risk of injury minimized.
  • the stripping device can so very simple and reliable, but also be trained relatively safely.
  • An exemplary embodiment is also preferred the stripping device in which the separating element flexibly attached to a support element is.
  • the separating element can therefore perform an evasive movement carry out so that the risk of injury a minimum is reducible.
  • the separating device at least has a separating element in a rest position is relocatable, and thereby the risk of injury can be significantly reduced.
  • the separators are arranged so that a Injury for operators is practically impossible is.
  • the dividers are off this rest position can be shifted to a working position, in the one running from the baffle Insertion strip is knocked off.
  • An embodiment is particularly preferred the stripping device in which the separating element designed as an elongated plastic thread one end of which is in rotation removable support element is attached and its distal end facing away from the support element a rest position can be shifted to a working position is.
  • the thread end is when the support element is stationary no risk of injury for operators even in operation of the separation device the risk of injury is reduced that the free-standing end that the insertion strip tees off when hitting the body surface an operator can avoid, so that at least serious injuries can be avoided.
  • FIG. 1 shows three functional positions one briefly below as a facility 1 designated stripping device, the interacts here with a transfer device, which is also called a baffle 3, which is pivotable on a scraper bar 5 of a machine for the manufacture, which is only indicated here or processing a web, in particular paper web, is appropriate. From the illustration is a material web 9 running from a roller 7 recognizable.
  • the Material web 9 - Before the start of a transfer process, the Material web 9 - in a known manner - an insertion strip cut off, which led through the machine shall be. Once the insertion strip is complete is passed through the machine, the Width of the material web to the desired dimension, namely reduced to the total width.
  • receiving or guiding devices 11 which serve the Material web or the insertion strips take.
  • baffles as an example 13 and 15 indicated.
  • separator 19 is provided, which is used during a transfer operation to cut off the material web 9.
  • the material web 9 runs, as indicated by an arrow 21, on the baffle 3 along and down.
  • the guide plate To transfer the web of material is the guide plate with the help of a Swivel device 23 from its in the top Partial view shown starting position clockwise panned. This gets the free End 25 of the guide plate 3 running material web 9 in the effective range of the separator 19 and is knocked off.
  • the baffle 3 In the middle representation the baffle 3 is located in FIG. 1 in a transition position in which the material web is just 9 is separated. The baffle 3 is however - as from the lowest partial representation in Figure 1 can be seen beyond this position pivoted so that the material web 9 in the area the receiving or guiding device 11 arrives, where they are first taken over by the guide plate 15 becomes.
  • FIG. 1 shows that knocked off one end 9 'of the material web 9 was so that the material web 9 of the Recording or guide device 11 are recorded can.
  • blowing devices 27 are provided be known per se, so that on their Functional description is omitted here.
  • the baffle 3 remains in the bottom view position shown in Figure 1 until the Material web 9 from a not shown here subsequent roller of the manufacturing or processing machine is taken over.
  • the baffle 3 can then be shown in its above in Figure 1 Starting position be pivoted back. It is then also possible, the separator 19 and the blowing devices 27 to deactivate.
  • belt devices can also be provided, whose belt surfaces facing the material web 9 move in the direction of transport of the material web.
  • a belt device is shown in Figure 2.
  • the mode of operation corresponds to that based on guide plates explained in FIG. 1.
  • a belt device 15 ' which is used by the baffle 3 Record and forward material web 9.
  • an arrow 29 the direction of movement of the material web 9 receiving and conducting Runs 31 of the belt device 15 'can be seen.
  • separator 19 arranged a support member 33, which by a suitable Drive 35 via a suitable power transmission device, here for example about a Toothed belt 37 is rotatable.
  • the direction of rotation is arbitrary. It is assumed here that the support member 33 against the Turns clockwise around an axis of rotation 39.
  • Support element 33 There are two opposite ones on the support element 33 Separating elements 41 and 43 attached.
  • the first End of the separating elements is in a suitable way Support member 33 attached while the second, distal End over the outer boundary surface of the Support element 33 protrudes when and during that Support element 33 rotates.
  • FIG. 3 again shows a part of a recording or guidance device recognizable, which also takes place here a baffle explained with reference to Figure 1 comprises a belt device 15 'on which the Material web 9 from the table or baffle 3 is applied.
  • the one shown here Embodiment are on the baffle 3 facing End 17 'of the belt device 15' two Separating devices 19 are provided, which are quasi mirror images are trained: from the side of which Material web receiving strand 31 are used as a drive 35 serving engines are provided, each one Set support element 33 in rotation.
  • the support elements 33 are located within the lateral boundary edges der Trums 31.
  • the supporting elements are an exemplary embodiment driven in opposite directions.
  • Both support elements 33 are in turn with two Separating elements 41 and 43 provided that the End facing away from support element 33 with weights 45 and 47 are provided. Also the representation in figure 3 shows the separation devices 19 in operation. The That is, the separators 41 and 43 are practical perpendicular to the axis of rotation 39 of the support elements 33. Figures 2 and 3 thus show the separating elements 41 and 43 in their working position in which they have a knock off the material web 9 transferred from the guide plate 3.
  • Figure 3 is the left separator Rest position 49 of a separating element is dashed drawn in:
  • the weight 45 bends the separating element 41 - following gravity - down.
  • the separators 19 shown here the separators are all designed so that they The support elements 33 come to a standstill as indicated here Take rest position 49.
  • a separator 41 attached, which, like explained with reference to Figures 2 and 3, on its distal End has a weight 45. With solid Lines is the working position of the divider 41 drawn. With dashed lines its rest position 49.
  • the separating element 41 it is. obvious that it is made of an elastic material consists. However, it is also possible to be rigid in itself Separating elements 41 'to be used, which are suitable Are pivotally attached to the support member 33. 4, it is assumed that that the separating element 41 'at its the Support element 33 facing away-distal end also carries a weight of 45 '. With a quick Rotational movement of the support element 33 about its axis of rotation 39, the separating element 41 'is thus turned outwards its working position pivots that it essentially is perpendicular to the axis of rotation 39. in the Standstill of the support element 33 tilts the separating element 41 'to its rest position 49' and essentially hangs vertically down.
  • the separating element 41 which is made of an elastic material and when the supporting element 33 is at a standstill is bent downwards by the weight 45.
  • the separating device explained with reference to FIGS. 1 to 4 19 does not represent an operator Risk of injury if the support member 33 in Rest is.
  • the separators 41 and 41 'on their Ends can also be formed with sharp edges, are then in their rest position 49 or 49 'pivoted and only stand little about the outer boundary surface of the support element 33 beyond.
  • the ends of the Separating elements 41 and 41 'opposite the support element 33 movable so that it is an evasive movement can perform when an operator does it touched. This evasive movement also leads constantly remaining in his working position Separating element 49 made because of its material properties sufficient flexibility and at the same time has such stiffness that it's not by its own weight - gravity is subsequently bent.
  • Wires can also be used or wire ropes are used that are so elastic are that the separators, especially if they are weighted at their ends, at Standstill of the support element bent downwards are, so that a risk of injury is practically excluded is.
  • Separators are particularly preferred for which the number of separating elements is selected that an imbalance is avoided. It is conceivable also, with separators with a single Separating element on the support element 33 a corresponding Attach counterweight to an unbalance to avoid.
  • the rigidity of the separators and the size of the weight provided at the end of the separating element can be adapted to the material web properties become. It is conceivable that with very light paper webs the weight can be dispensed with. In the case of heavier tracks, you can do so without any Cutting weights on your radially outer side formed with sharp edges to increase the discount effect. Also in this case the risk of injury remains in the operation of the separation device for operators reduced because there are no fixed knives are used.
  • the ends of the dividers can because of their flexibility, that is, because of the elasticity of the separating elements respectively due to the pivoting suspension when Impact on an operator's body surface perform another evasive movement.
  • Support element 33 modified as follows :
  • the basic body of the Support element for example, radially extending recesses be introduced into the separating elements be introduced. These can be achieved through a spring elastic Element is anchored to the support element, that applies a retraction force to the separating elements. If the support element is set in rotation, can the separating elements against the retraction force step out of the recesses and a web of material guided past the support element knock off. Can in the retracted position the dividing elements pose no risk of injury to operators mean, so here a high Operational security is given.
  • This advantage also results from a method for knocking one off in a manufacturing machine or processing a web, in particular paper web, insertion strip that is to be threaded characterized in that the insertion strip with With the help of a flexible separating element of a separating device is knocked off. A squeeze or injury to the operator between two interacting knife edges is excluded. Others without a counter element knives acting on the insertion strip can be omitted because the flexible separating element knocking off an insertion strip.
