Definitions

  • the invention relates to a method of producing a spring insert from strings of springs which are individually encased in a pocket of material, so-called pocketed springs, said strings having an adhesive applied and being compressed to form the spring insert.
  • a method is known from the description provided in EP, B1, 0154076 and EP, A2, 0155158, whereby heat-fusible adhesive is applied to the outer string in the spring insert, after which an additional string is pressed into place and glued together with the first string.
  • the spring insert is finished after a suitable number of strings have been glued together.
  • it can be incorporated into a mattress, a cushion or the like in a commonly-known manner.
  • the known method is limited to the production of spring inserts with the same resiliency characteristics in the insert for the whole extent of the insert.
  • the spring insert comprises only one type of pocketed spring, in that all of the strings are cut from the same length.
  • the adhesive is applied by means of movable nozzles which, during the emission of the adhesive, are led along the outer layer of the spring insert. This means that the pressing-together of the subsequent string must await the application of adhesive before the string can be glued to the preceding string. This gives rise to the risk of the glue running or flowing out, so that the gluing-together either becomes too weak or too extensive, depending on the state of the adhesive at the moment that the compression is effected.
  • strings with different characteristics with regard to both dimension and form of the spring elements for the changing of the resiliency characteristic, and pockets can be made of material which can be more or less flexible for changing of the damping characteristic.
  • the application of the adhesive to the string while this is in movement provides the advantage that the production process is not delayed, but is limited only by the speed with which the string is fed past, and also that the construction is simple and without moving parts.
  • a plant for the execution of the method is illustrated in fig. 1.
  • the plant comprises a feeding section 1, which will be described in more detail with reference to figs. 2 and 3, a turning section 2, which will be described in more detail with reference to figs. 4 and 5, and an adhesive application section 3 and a compression section 4 which will be described in more detail with reference to figs. 6 and 7.
  • the feeding section 1 consists of a frame 5, on the top of which are supported a number of wheels 6 corresponding to the number of pocket-spring lengths 7, 8.
  • lengths 7 and 8 can have different resiliency and/or damping characteristics, so that in the example embodiment shown there can be produced a finished spring insert 9 consisting of two different types of pocket-springs.
  • the wheels 6 are preferably sprocket-formed so that the lengths 7 and 8 can be fed by rotation of the wheels.
  • a shield 10 can be mounted over a part of the wheels' circumference.
  • each set of wheels 6 there is mounted a further set of drive rollers 11 for each length 7, 8, so that each individual length can be fed in a precise manner.
  • the wheel sets 6, 11 will be synchronized by means of a chain drive or the like.
  • a cutting mechanism 12 comprising two jaws 13 which can be moved in a reciprocating manner by means of an actuator 14, so that the lengths 7 and 8 can be fed between the jaws 13 when these are separated.
  • the drive roller 11 can feed a certain number of pockets in the length 7 and 8 so that a given number of pockets, corresponding to the length of the string 15, will form one element in the finished spring insert 9.
  • the jaws 13 are closed and the length is cut over either mechanically or thermally.
  • This conveyor carries the string 15 further to an angularly-extending belt 17 which leads the string 15 forward to the turning section 2.
  • this section is configured with a conveyor belt 18 on which the string 15 is fed forward in the section.
  • a boom 19 operated by actuators 20 pushes the string over the side where it falls down on a side-stop 21. As shown in fig. 5, the side-stop is thereafter tipped so that the string falls down into a gutter 22.
  • the string 15 is fed into a chain conveyor 23 which is moved from the turning section 2 and further through the compression section 4.
  • the conveyor 23 feeds the string 15 past an adhesive application device 24 which can be of any suitable type.
  • a fluid adhesive is advantageous, the reason being that this can be pumped out through nozzles via a pipe 25. This makes it possible for the adhesive to be pumped out in shots, and the adhesive 26 can hereby be applied to the outer side of each pocket-spring in the string as this passes the nozzle(s).
  • the chain conveyor 23 stops when the string 15 is standing opposite a pusher arm 27, this being provided with an end profile which enables it to lie up against the string 15.
  • an actuator 28 can feed the string 15 with adhesive 26 on to an underlayer 29 where it can be pushed up against preceding strings for gluing together with the outermost string.
  • the spring insert 9 is hereby built up of strings 15 which one after another are glued together to form the finished insert 9.
  • the lengths 7 and 8 with the desired resiliency and damping characteristics and dimensions are fed to the plant in the form of endless lengths of pocket-springs 7 and 8.
  • spring inserts of any desired kind and character, also including spring inserts comprising pocket-springs of different heights.
  • the plant is controlled in a commonly-known manner by microprocessors so that it is possible to select to feed strings of any desired length, said strings then being tipped upright and receiving an application of adhesive before the final compression.
  • the whole method is controlled so that all movements are synchronized, whereby strings can be produced at a very high rate of production, the reason being that the whole of the flow can be effected at the same tempo.
  • pocket-spring strings is determined by the activation of the sets of feeding wheels, whereby strings can be produced at normal rates of production, even when there are frequent changes between the strings.
