Definitions
- the invention relates to a device for producing a link belt, for. B. for paper machines, consisting of a plurality of monofilament strands according to the preamble of claim 1.
- the invention has for its object to improve the definition of the last helix fixed by a coupling wire, so that the receiving opening of this helix for the helix to be subsequently inserted is as trouble-free as possible.
- An embodiment of the invention is also concerned with guiding the helix from the helical conveyor to the insertion point, whereby it is proposed according to a further feature that buffer containers are switched on, in which a tension compensation of the helixes can take place.
- an embodiment of the invention deals with the problem of inserting the coupling wire to be inserted without problems, the rounding of the head of the coupling wire being particularly important.
- the component serving to fix the last coil strand 3 has the reference symbol 60 and can be moved up and down in the direction of arrow F 1 and can be pivoted back and forth in the direction of arrow F 2 , ie pivotable about the pivot axis 67.
- a second fixing element 80 is provided, which is movable in the direction of arrow F 3 .
- a device can also be seen from FIG. 2, which is used to feed a coupling wire 6, which is used to connect the individual coils.
- This coupling wire 6 is shot into the helix 2 inserted into the last helix 3, so that this last helix 2 is thereby fixed.
- a fixation wire feed device 90 can be seen from FIG. 2 and in FIG. 7 the fixation wire 91, which can be made of metal and is inserted over the entire width of the link belt, can be seen, which is in the free space 8 of the last coil strand 3 before inserting the new coil strand 2 has been introduced.
- FIG. 2 also shows a separating device 93 equipped with a glow wire 92. This separating device is pushed into the area of the inserted coupling wire 6 after the fixing wire has been removed and cuts through the coupling wire, at the same time melting the head of the coupling wire, as is the case is shown particularly clearly in FIG. 6. 6 also shows a guide device 94 for the fixing wire 91.
- the insert 18 moves in the direction of the arrow F 4 , and the supply channel 16 is open at its lower end, so that the feed wheel 14 can now insert the coil strand 2 to be inserted into the last coil strand 3.
- slide elements 19 and 20 are provided above the actual joining point and are designed in a cutting-like manner on their front side.
- the slide element 19 has severed the coils and closed the supply channel 17, while the slide element 20 has been withdrawn and allows the coil to pass through.
- the actual insert 18 can be driven via electromotive aids known per se and corresponding feed devices.
- abutment elements immersed in the free space is shown, with these abutment elements being provided in addition to the fixing wire 91 in the embodiment according to FIG. 7.
- the abutment elements consist of individual lamellae 23 which have a central punching 24 with which they are pushed over a carrier 25.
- the carrier 25 has recesses 26 on its upper edge edge, into which the individual lamellae can be hung with their punched-out portions 24.
- the lamella 23 After fastening the carrier 25 to the main support element 27, there is a small free space between the upper edge of the suspended lamella 23 and the lower edge (cantilever retaining strip 17) of the main support element, so that the lamella can carry out a limited up and down movement without it their recess 26 came out.
- this lower edge can be designed by an elastic buffer element 27a, so that additional movements of the slats are possible here.
- the width of the recess 26 is selected such that the actual lamella 23 can also perform slight movements to the right and left, so that there is the possibility that the lamella itself will move downward in the direction of arrow F 1 of the component 60 can choose the space assigned to it in the spiral strand and then immerse it.
- the lower edge of the actual lamella 23, as can be seen at 28, is tapered and rounded, so that the immersion movement is facilitated and injury to the spiral strand is eliminated.
- the fixing of the last coil strand 3 takes place by means of the fixing wire 91, while the lamella 23 has the task of moving the link belt, in that the lamella moves together with the main support element in the direction of arrow F 2 .
- the spiral conveyor 11 with the drive motor 12 conveys the spirals to be removed from the storage containers into storage channels 16 and 17, which open freely above buffer containers 46 and 47, so that the spiral is released freely and relatively unguided into the respectively assigned storage container 46 or 47.
- the feed devices 48 and 49 are tubular and open freely in the region of the upper edge of the buffer containers 46 and 47, the radius of curvature of this region of the mouth being relatively large in order to achieve the most trouble-free conveying of the coil.
- the spiral conveyed by the spiral conveying device 11 and freely guided into the buffer container 46 or 47 lies in a circular manner in the buffer container approximately at the outer edge of the buffer container and then rises and is fed into the feed device 48 and 49.
- the procedure is preferably such that the mouth of the supply channels 16 and 17 lie diagonally with respect to the storage container 46, 47 opposite the mouth of the feed devices 48 and 49.
- This buffer container creates a memory in which tensions within the coil can be compensated, but the pressure of the spiral conveying device 11 is so great that it is possible to guide the coil correctly into the buffer container and to remove the coil from the buffer container properly.
- This pressure of the helical conveyor device 11 is supported by the train arising in the area of the joint 50.
- coating bodies 51 and 52 are provided which are fixedly connected to the insert 18 and which, in the exemplary embodiment shown, each consist of a guide tube 53 in which a coating element 54 and 55 is guided up and down, that seen in the direction of travel of the insert (this direction of travel is illustrated in FIG. 5 with an arrow F 4 ) is arranged inclined so that when the insert 18 moves, the coating element 54 strokes the upper edge of the helix.
- the device for producing the link belt can also be provided with a multiplicity of storage containers, feed channels and feed wheels for feeding more than two helical strands to the insertion point.
