Definitions

  • the present invention relates to a method and an apparatus for producing pocket spring cores.
  • Such methods and devices have become known in a large number of different embodiments.
  • individual coils of pocket springs are initially formed here.
  • These snakes contain a number of pockets, each pocket contains one or more feathers.
  • the pockets are closed against each other, e.g. by gluing or welding.
  • the covering consists of a fleece or fabric that has different material properties depending on the requirements. In principle, any suitable material can be used here; the term fleece is not to be understood as restrictive.
  • the invention proposes a completely new way of producing pocket spring cores. Individual snakes are no longer produced first, which have to be laboriously connected to one another, but first the wrappings or fleeces of the individual snake are connected, and then the springs are inserted. If necessary, the division into pockets can be added .
  • the main advantage now is that the desired number of snakes to be used, which essentially specifies the width of the pocket ferrule, is provided from the outset.
  • the length of the pocket spring core can be easily adjusted, as a measure of this can be the consumption of wrapping or the number of springs used.
  • each snake is already pre-sorted in the correct dimensions.
  • the individual wrappings are then arranged side by side and connected to one another.
  • a welded connection is preferred here, but of course gluing or another connection such as sewing is also possible.
  • the envelopes are then formed into a closed tube by overlapping the free ends and connecting them together.
  • welding is preferred, although the other connection options mentioned above can also be used.
  • the sheath is preferably wrapped around a tube.
  • the dimensions of the tube are adapted to the springs to be processed.
  • the springs are now supplied, this preferably being done by introducing the springs into the interior of the respective tube; in this interior the springs are then moved forward in the conveying direction over a certain path or up to a stop.
  • the springs do not necessarily have to be inserted into a tube after the casing has been formed. It is also possible to store the springs in the tube beforehand and then clock them in after the hose has been formed.
  • a partition is formed in each snake behind the inserted spring or springs. This can consist of a continuous weld seam, an interrupted weld seam or weld spots. In the following, only the term weld seam is used, which encompasses all the possibilities mentioned. Alternatively, gluing, sewing or another option can of course be selected.
  • nonwoven forming the covering must be moved in the conveying direction.
  • driven rollers can be provided, but it is also possible to effect the movement of the fleece together with the displacement of the springs. A combination is also possible.
  • the pocket spring core that is ready is then separated from the one that is still to be manufactured. It is preferred here if hot separation takes place, for example by means of a heated, displaceable wire. Alternatively, it is of course possible to use scissors or other mechanical release agents.
  • the finished pocket spring core is removed via a suitable device and, if necessary, reworked to a certain extent in order to achieve a uniform surface.
  • the entire production process can be carried out continuously or in cycles, with cycle production being preferred.
  • the three possible welding processes are preferably carried out here simultaneously.
  • the welding elements are then withdrawn and the casing is moved. As stated at the beginning, this is preferably done by introducing the springs, which are pushed to the front end of the respective snake and then further by a predetermined amount, which corresponds approximately to the maximum diameter of the spring. This movement can be supported by rollers or rollers that act on the casing.
  • Figure 1 is a side view of a device according to the invention.
  • Figure 2 a plan view according to arrow II in Figure 1
  • Figure 3 a side view according to arrow III in Figure 1;
  • Figure 4 the detail X of Figure 1;
  • Figure 5 the detail Y of Figure 1;
  • FIG. 6 the detail Z from FIG. 1;
  • Figures 7 to 9 views according to Figures 4 to 6, in which the nonwoven forming the envelope is shown.
  • FIGS. 1-3 show schematic overall views of a device 1 according to the invention
  • the device 1 comprises a stand 2, on which a plurality of rollers 3 are attached. As shown, these rolls can be arranged one above the other and support the fleece 23 in the required dimensions.
  • rollers 3 are, of course, as wide as the overall dimension of the associated fleece 23, so that if the rolls 3 were attached completely next to one another, a very large width would be achieved. To reduce this width, the rollers can be placed one above the other as shown.
  • the device 1 further comprises a forming and welding station 4, a pocketing station 5, a separating station 6 and a packer or transporter 7.
  • the forming and welding station comprises a tube 8, which can be provided with a funnel 9 on its side facing the rollers 3. This funnel 9 serves to facilitate the wrapping of the tube 8 with the fleece 23.
  • a slide 10 for moving the springs 27 is arranged in the tube 8. In the exemplary embodiment shown, these springs 27 are fed from below via a tube 11 and a further slide 12.
  • the total supply of the springs 27 can e.g. take place laterally, ie from above or below in FIG. 2.
  • one or more conveying stations 16 with one or more driven rollers can be provided. It is of course also possible to achieve this funding via the slide 10.
  • the separation station 6 comprises a wire 19 which is heatable and movable in the direction of the arrow 20, 21.
  • the wire is designed and brought to such a temperature that it can cut through the fleece 23 without difficulty.
  • the packer 7 consists of two circulating belts 17, 18, between which the finished pocket spring core is accommodated. It is preferred if the distance between the bands 17, 18 is adjustable in order to be able to exert pressure on the pocket spring core to compensate for various unevenness.
  • FIG. 4 and 7 show the connection of individual fleeces 23 and thus the connection of the individual snakes.
  • every second tube 8 is provided with a recess 22 into which a first sonotrode 13 engages. As shown in Figure 7, this sonotrode 13 is movable to one
  • the sonotrode 13 generates three welding spots 24, which can be attached one above the other, next to one another or also at an angle.
  • the distance between individual welding points can be chosen essentially freely.
  • the distance between the individual connections, that is to say in FIG. 7, from the welding points 24 to the sonotrode 13 can also be chosen essentially freely.
  • Figures 5 and 8 show the subsequent forming of the
  • Fleece 23 to a closed hose.
  • the projecting ends of the fleece 23 are folded in so that they overlap one another.
  • a weld seam 25 is made in this overlap area by means of the sonotrode 14.
  • the sonotrode 14 can also be designed to be movable.
  • Figures 6 and 9 show the bagging.
  • the prerequisite for bagging is that the closed hoses, ie the snakes without springs, are first closed at their front end.
  • a spring 27 is then brought up to the front of this seam (not shown) in each line via the pipes 8, 11 and the slides 10, 12.
  • All queues 30 are then moved forward by a certain, predetermined distance. This can be achieved either by the slide 10 or by the conveyor station 16 or by a combination.
  • the intended sonotrodes 15 are moved downward for the corresponding movement. As soon as the first spring 27 has passed through the sonotrodes 15, they move up again and produce a weld seam 26, so that a pocket 28 is formed.
  • the Weld seam 26 can be interrupted, as shown. Of course, it is also possible to apply a continuous weld seam or only one or more weld spots.
  • the sonotrodes 15 make two weld seams 26 at a short distance from one another. Between the weld seams, the wire 19 then cuts through the separation station.
  • the finished pocket spring core is taken up by the packer 7, possibly somewhat balanced and then processed further or fed to a warehouse.
  • the order or type of springs to be processed can be varied.
  • a different type of feather can be used for each snake; it is also possible to use several different feathers per snake. This is particularly important in the production of pocket spring cores, since these are usually divided into areas with different requirements, in particular different weight loads. With the present invention, it is readily possible to pre-program certain sequences of springs and then to feed them.
