Definitions

  • the present invention relates to a method and apparatus for rolling and packaging compressed flexible material such as mineral wool.
  • Insulation wool is used for insulating e.g. houses in order to reduce energy loss.
  • Insulation wool is a material comprising a lot of air and in order to save space both when transporting, storing and handling the material, it is an advantage to compress the material before packaging. Obviously, this is not only an advantage when it comes to insulation wool, but also other material comprising air, such as foam used in inter alia furniture, e.g. in mattresses, could be compressed to save space. It is known to stack and compress compressible products, such as insulation wool, in the same process.
  • Another method of compressing and packaging wool is to compress and roll the wool in wool rolls. Using rolls can be advantageous in situations where large segments are to be covered by wool, which can be done much faster by just rolling out the roll instead of having to position a number of product pieces next to each other.
  • the first part of the wool length may be over- compressed, resulting in plastic deformation of the wool, whereby it does not regain its full size when unpacked, and thereby does not regain its proper isolative properties.
  • Another problem is that in the known methods of rolling, the first rounds of rolling cannot be optimally controlled, which often results in the first roll rotations being quite random thus bending the material in various directions.
  • compressed flexible material any material having a substantial elastic compression range, or in other words, that the material is able to fully recover from considerable compression, such as 30% or 90% compression, regaining substantially its original volume and dimensions.
  • Mineral wool is a typical type of such a materials, such as glass wool, slag wool or stone wool.
  • this elastic compressibility is obtained at least in part by a high air content, possibly with open cells, where air is free to travel in and out of the material.
  • wool is understood this flexible material in either compressed or uncompressed form.
  • a roll-up belt is used, which is usefully flaccid and stretched in different regions over time.
  • a loosened belt is understood a portion of a belt where the distance it covers is less than the distance coverable by the same belt portion without damaging the belt, or, in other words, a flaccid belt or a slack belt.
  • the belt is never completely flaccid, slack or loose, but comparatively so, relative to other portions and at other times.
  • the flaccidness may be understood as a descriptor of regions able to supply excess belt.
  • an automatic rolling of flexible material is obtained solving the above-mentioned problems by letting the adaptably expanding meeting loop cavity ensure that the rolling is initiated in a controlled manner, and furthermore, that one machine may be fitted to roll flexible material of various dimensions and characteristics.
  • it relates to a method wherein at least two of said rollers are active and wherein gradually increasing the length of the segment of said roll-up belt in said meeting loop cavity comprises controlling the rotation speed of at least one of said at least two active rollers along said belt pathway.
  • the speed is adaptable during operation.
  • one of the active rollers may drive the belt instead at a reference speed and its speed may not be controllable.
  • another active roller then adaptably controls the meeting loop cavity expansion.
  • both are controllable.
  • the expansion of the meeting loop cavity can be precisely controlled by using the two active rollers at different speeds.
  • it relates to a method, wherein the compression of the wool is obtained by moving the wool between an upper feed belt and a lower feed belt, and wherein the feed belts are inclined relative to each other, whereby the distance between their transport surfaces decreases in their transport direction. Thereby, the compression of the insulation material moving along the surface of the lower compression belt is gradually increased.
  • said belt pathway comprises a first pathway segment defining a route between said two active rollers and a second pathway segment defining another route between said two active rollers, wherein said moveable roller is located along said first pathway segment and said meeting loop cavity is located along said second pathway segment.
  • an apparatus comprising at least one limiter unit, where said at least one limiter unit is adapted to reduce the speed of said belt along said belt pathway, and where said limiter unit is positioned along said belt pathway after said meeting loop cavity in the belt moving direction.
  • the limiter unit is a passive roller or an active roller.
  • the limiter unit may be an active roller providing a reduction of speed by actively rotating at lower speeds than the oncoming belt, or it may be a passive roller fitted to supply a static or dynamic speed reduction.
  • said limiter unit is the first roller positioned along said belt pathway after said meeting loop cavity in the belt moving direction.
  • a method whereby gradually increasing the length of the segment of said roll-up belt in said meeting loop cavity comprises decreasing the pull onto said belt inside said meeting loop cavity from downstream said meeting loop cavity.
  • brakes may be employed, whereby the effectiveness of the expansion of the cavity may be easily seen and optimized to different materials and speeds, while allowing the system to operate at optimum efficiency ranges.
  • it pertains to an apparatus adapted to perform this function by decreasing the speed of the downstream belt with a limiter unit.
  • the limiter unit may be a brake or it may be a motor adapted to be able to brake or any other unit able to slow down the belt.
  • an upper inlet roller is the limiter unit. By using an upper inlet roller as limiter unit, travel time between the meeting loop cavity and the limiter unit is minimized, allowing quick feedback and thus control of the rate of expansion of the meeting loop cavity.
  • the pressure of said flexible material onto said belt as it meets the belt inside said meeting loop cavity is enough to gradually increase the length of the segment of said roll-up belt by drawing belt into said meeting loop cavity.
  • it pertains to an apparatus adapted to perform this method. This is normally not possible because inertia in the belt along its path necessitates releasing substantially more belt and slacking the belt considerably before the resistance has decreased enough for expanding the cavity in this way. Another problem produced by this is that the rate of expansion of the cavity is then not controlled.
  • the neck of the meeting loop cavity is narrowed as the cavity is expanded and the roll size increased.
  • narrowing the neck is meant that the opening of the cavity is made smaller. This allows the wool to touch, thus promoting rolling and not allowing it to leave the cavity along the belt, even for different thicknesses of wools.
  • it relates to an apparatus adapted to narrow the neck.
  • it pertains to an apparatus where said loop cavity is retained by fingers, said fingers protruding onto said belt inside said meeting loop cavity. These fingers do not protrude deeply enough to obstruct the path of the flexible material. Thereby, feeding belt to the cavity has the predictable effect of expanding the cavity inwards.
  • the belt making up the cavity might hang out and so feeding belt would simply increase the protrusion of the belt outwards.
  • the fingers By the fingers not extending fully inwards onto the belt, they are adapted to not obstruct the path of the wool, making their use considerably simpler.
  • the fingers are mechanically removable, which allows for them to be withdrawn to roll materials in the cavity with broader profiles without obstruction, such as plastic packaging, which is often broader than the wools they are fitted to package.
  • Fig. 1 is a side view of the mineral wool packager at a time prior to formation of a wool roll.
  • Fig. 2 is a side view of the mineral wool packager at the beginning of formation of a wool roll.
  • Fig. 3 is a side view of the mineral wool packager almost finished rolling the wool.
  • Fig. 4 is a side view of the mineral wool packager as it has released the finished roll.
  • Figures 1 - 4 illustrates the process of making rolls of flexible, compressed material according to the present invention.
  • Fig. 1 illustrates the mineral wool packager 1 prepared to form a roll of wool 4. Furthermore, it also illustrates the wool being compressed 41 between two feed-belts 2, 3 adapted to receive the wool between the two belts.
  • Each belt is a conventional transporting belt, where a belt rotates around rollers and the rotating direction and also the transport direction are illustrated by the arrows 5.
  • the upper compression belt 3 is mounted in an inclined manner relative to the lower compression belt 2, whereby the distance decreases between the two belts in the transport direction of the transporting belt. This decrease in distance compresses the insulation material between the belt as the insulation is moved along the transport belts.
  • One or both of the feed-belts 2, 3 are at least vertically moveable, thus affording control over the degree of compression 41 , achieving an appropriate thickness of compressed wool 42.
  • This allows multiple thicknesses and types of wool to be inserted into the mineral wool packager at their effective compressions, such as appropriately compressing stone wool with a thickness of ten and thirty centimetres respectively.
  • the embodiment of the mineral wool packager according to fig. 1 consists of a roll-up belt fitted onto a number of passive rollers 12, 12', 17, 19, 181 as well as two active rollers 1 1 ,
  • the mineral wool packager has a controllably moveable roller 17, whose displacement along axis A shortens or lengthens the belt pathway, thereby either slacking or tightening the belt. In fig. 1 this displacement is vertical, but in other embodiments, the displacement may be horizontal or any other angle.
  • a motor controls the movement along axis A.
  • a counterweight is attached to the moveable roller
  • an expandable meeting loop cavity 14 is located, so that compressed wool 42 encountering the belt 10 enters this cavity.
  • this cavity is illustrated in its initial, contracted position.
  • the belt pathway is kept expanded into the cavity-shape by two fingers 13 in the contracted position. Because the belt 10 is broader than compressed wool 42, the fingers 13 holds the belt in the cavity, but adapted to not protrude deeply onto the belt, whereby they do not obstruct the path of the wool as it enters the cavity. Thereby, the fingers hold the belt in a minimal cavity size but does not obstruct the wool from pressing against the cavity.
  • the fingers 13 are mechanically removable during operation, allowing broader profiles of for example plastic film to roll unobstructed into the cavity at a convenient time, for example allowing packaging the wool in an outer packaging layer.
  • the belt 10 is rotated by at least one active roller 1 1 .
  • This active roller is controllable, by which is understood that it has a controllably variable speed. This speed is adapted based on the need for loose belt in the meeting loop cavity.
  • belt feed to the cavity can be precisely controlled, whereby wool of varying materials and thicknesses can be rolled in the mineral wool packager according to the invention.
  • the mineral wool packager according to the invention is thus adapted to supply a tightly fitting cavity and a precisely paced expansion, even as the machine becomes older and tolerances creep.
  • the roller 16 is an active roller.
  • the roller 16 might also be a passive roller.
  • two active rollers 1 1 , 16 are provided, where the direction of the rotation of these is seen by rotational arrows 5.
  • Counter-rollers 1 1 1 , 161 are used to ensure the grip of the active rollers onto the belt to ensure a high degree of power transfer as well as a controlled belt displacement.
  • the geometry of the belt pathway will determine where the flaccidity expresses itself the most. If the active rollers operates normally following the belt becoming flaccid, the flaccidness will travel along the belt pathway and will likely result in a concave line immediately before the first active roller 1 1 as well as a slightly more flaccid pathway upstream of the first active roller all the way to the second active roller.
  • the first active roller is not a passive roller; however, the flaccidness is substantially kept at a first belt-segment 101 corresponding to upstream relative to the first active roller, and between the two active rollers, while the flaccidness cannot enter a second belt-segment 102 corresponding to downstream from the first active roller and between the two active rollers.
  • the two active rollers displace the belt at the same speeds, flaccidness on one belt-segment 101 or 102 cannot travel to the other segment. Substantially, only by operating the active rollers at different speeds the flaccidness may travel between belt segments.
  • the amount of flaccid belt fed to the meeting loop cavity is precisely controlled. Furthermore, because the first active roller is placed substantially immediately upstream of the meeting loop cavity, the wool pressing against the belt inside the meeting loop cavity does not need to overcome the forces inherent in drawing belt from a concave belt line under the mineral wool packager to expand the cavity, but instead the first active roller actively feeds flaccid belt at a rate matching the rate of inserted wool, accounting for wool thickness and type. In one embodiment of the invention, the first active roller is adapted to respond to the wool pressing against the belt, feeding belt according to forces sensed from the belt.
  • Fig. 2 illustrates an embodiment of the present invention, where the compressed wool 42 is beginning to be formed into a roll inside the meeting loop cavity 14.
  • the moveable roller 17 is moved upwards, shortening the belt pathway, allowing the first active roller 1 1 to feed flaccid belt to the cavity 14, which is then expanded by the compressed wool 42.
  • Edge rollers 12, 12' define the outer edges of the meeting loop cavity, and in one embodiment, one or both of them are moveable, allowing the meeting loop cavity to substantially close as the roll of wool is being formed. This ensures that the wool cannot leave the meeting loop cavity, as the height between the edge rollers 12, 12' may be adjusted to less than two times the height of the compressed wool.
  • the wool traveling along the roof of the cavity may by its own weight fall onto the wool traveling along the floor of the cavity.
  • the gap between inlet rollers 12, 12' being less than two times the height of the compressed wool, ensures contact between the upper and the lower layer. Friction between the two layers ensure a bend at the tip of the wool traveling at the roof, whereby the formation of the roll is initiated with no or minimal plastic deformation of the wool.
  • the geometry of the cavity precisely, such as by controllably feeding loose belt to the cavity.
  • This may for example be according to the rate of insertion of wool, as well as the type and thickness of wool used.
  • the cavity can be so small as to force the upper layer of wool to travel along the lower layer for the entire length of the cavity (not shown), thereby creating friction, which initiates the rolling.
  • a larger cavity can be created, allowing the upper layer to fall onto the incoming layer by way of gravity, as seen in fig. 2.
  • the amount of flaccid belt fed may vary.
  • the belt feed during roll initiation may be non-linear or stop entirely or even reverse momentarily.
  • An example may be quickly feeding a large amount of belt to the cavity, whereby a large cavity is created, ensuring that the wool has relatively far to travel along the roof of the cavity.
  • the cavity may then for example be contracted again, ensuring a tight fit and so retaining the compression.
  • the moveable roller is further displaced along axis A, allowing the meeting loop cavity 14 to attain a desired size for a wool roll 43.
  • an outer layer for example of plastic film, is fed conveniently along the upper feed-belt 3 and into the meeting loop cavity, thereby encapsulating the wool roll. This allows the roll to retain its compression even after removal from the mineral wool packager.
  • the bottom of the mineral wool packager is rotated substantially sideways around a roller 181 , allowing the packaged wool roll out of the meeting loop cavity.
  • Machine section 18 is rotated around roller 181 , whereby the wool roll is expelled, ready for further processing, storage and/or transportation.
  • the roller 17 is displaced to accommodate any changed belt pathway distance between rollers 12 and 12', corresponding to the meeting loop cavity of figs. 1 - 3.
