Definitions

  • the present invention relates to a method for the radial compression of cylindrical bodies made of compressible material, in particular rolls made of wound flat structures, especially those which expand again after the pressure has been removed and thus revert to the original state, and a device for carrying out this method .
  • Cylindrical bodies such as those obtained by rolling up web material from loose, air-containing materials such as fluffy textiles, fleeces, crepe, foam webs and the like, are voluminous and require a large storage and transport volume, which places a considerable burden on storage and transport costs.
  • this object has surprisingly been achieved by leading the cylindrical bodies in question through a tapering, rotationally symmetrical, approximately funnel-shaped space in a helical retative movement, the narrowest cross-section of which corresponds to the extent of the desired radial compression of the cylindrical body, and the inner surface of which consists of rotating elements, which enables the body to be compressed to be rolled off almost without sliding.
  • the helical, approximately friction-free relative movement according to the invention is obtained according to the invention in that the casing of the tapering space serving for compression consists of several regularly and rotatably arranged cylindrical bodies which are at an angle to the longitudinal axis of the body to be compressed such that they are the ones to be compressed Push body forward.
  • the roll-shaped material is increasingly compressed by means of the cross-section of the space tapering along the longitudinal axis.
  • the present invention accordingly relates to a method for the radial compression of cylindrical bodies made of compressible material, in particular of rolls made of wound flat structures, which is characterized in that the body to be compressed is axially defined by a rotationally symmetrical space tapering in the direction of transport, the diameter of which on the the narrowest point is smaller than that of the body to be compressed, and the jacket of which is formed by several regularly arranged, co-rotating cylindrical bodies, crossing the axis of rotation of the space in the second half seen in the direction of transport at an angle of 5 to 45 °, but not cutting is moved, the body to be compressed exerts a helical relative movement with respect to these bodies forming the shell of the room, and is compressed depending on the ratio of its diameter to the diameter of the narrowest point, and this compression by wrapping h a strip or strand material is fixed in the narrowest part of the room.
  • the rotationally symmetrical bodies of the casing itself are driven and are in rotation. If the body to be compacted, which does not need to be supported at all, but can also be freely rotatably supported, is introduced into the rotationally symmetrical space, as soon as its circumference touches the rotating rollers, it is grasped by them and thereby in an opposite direction Rotation offset. Since the rollers are not only at an acute angle to the rotational symmetry axis of the body, but also cross them, it is simultaneously pushed forward and increasingly compressed.
  • the rotating roller-shaped bodies in addition to their own rotation, must also be set into a common, synchronized rotational movement about the rotational symmetry axis of the space serving for compression, which is also the longitudinal axis of the body.
  • the size of the angle at which the roller-shaped bodies are positioned relative to the longitudinal axis of the space serving for compression is decisive for the height of the aisle helical raltiv movement, so that this angle allows to adapt the conditions during the compression of the nature of the body to be compressed, in particular the type and nature of its surface or the back pressure that the body exerts during the compression.
  • the material to be compressed is one that has a very strong and rapid ability to recover, it is also advisable to ensure that the spaces between the roller-shaped bodies that form the surface of the space are kept as small as possible. Otherwise there is a risk that the material to be compressed swells up between the roller-shaped bodies.
  • the cylindrical bodies are preferably in the form of a cylinder. If, in addition to the compression according to the invention in the radial direction, a certain axial compression is also desired, this can be achieved in that the cylindrical bodies taper in the direction of movement. e.g. B. that of a single-shell rotational hyperboloids with low curvature, which merges into a cylinder at the narrowest point, or a truncated cone is given.
  • the narrowest point of the space is in the second half as viewed in the direction of transport, preferably even in the last third of the space.
  • the prerequisite for this is that the compression of the end space has a larger diameter on the input side than on the output side.
  • Another object of the present invention is a device for carrying out the method according to the invention, which is characterized by at least 5 rollers arranged at a rotational symmetry at an intersection angle alpha of 5 ° to 45 ° to their common axis of rotational symmetry with the same diameter, the surface lines of which form a single-shell rotational hyperboloid Ends on two ring-shaped frames, of which the frame on the output side has the smaller diameter, are fastened in a rotationally symmetrical arrangement, and by a roller for tape or packaging material arranged outside the space enclosed by the rollers in the region of its narrowest cross section, which is provided by a braking device is fed between two rollers to the cylindrical body located within the space formed by the rollers and by means of a removal and transport device for the adjoining the frame on the output side n compacted body.
  • the ring-shaped frames, to which the rollers which delimit the space serving for compression are fastened are rigid; H. So arranged immovable, so that the rollers are fixed in their position and can only perform a rotary movement about its own axis.
  • the body to be compressed must be freely rotatable in the device according to the invention so that it can exert a helical relative movement. This can be done by appropriate storage, which allows a rotational movement.
  • the body to be compressed is preferred by a suitable device such.
  • the device according to the invention can also be designed in such a way that not only the rollers which delimit the compacting space can be rotated but also those two annular frames to which these rollers are attached. Either the rollers alone or the annular frames rigidly connected to one another or both can be driven. If the frames are driven, their drive must cause a direction of rotation in the same direction as that of the rollers.
  • means are provided which fix the body to be compressed against rotation, but allow axial movement, which z. B. can be done by attached to the inlet and outlet in the radial direction pressed rollers.
  • the rollers which form the rotationally symmetrical body of the device according to the invention are preferably cylindrical in shape, but can also have the shape of a truncated cone or a rotational hyperboloid. In all cases, the length is a multiple of its diameter. If these rollers have the shape of a truncated cone, it is advisable not to choose too large the difference between the diameter of the base and that of the top surface, although in all cases it must be ensured that the enclosed space has the tapered shape required according to the invention .
  • the ratio should preferably not be greater than 2. In this case, the base is always attached to the frame on the input side.
  • the device according to the invention Since the desired degree of compaction varies depending on the nature of the material to be compacted and depending on the intended use, it is expedient to equip the device according to the invention in such a way that the angle alpha varies and the degree of compaction can thus be changed or adapted. This can be accomplished very simply in that one of the two ring-shaped frames is rotatable relative to the other to a certain extent about the longitudinal axis of the device and is fixed in the desired position.
  • the packaging material must be fed in at the narrowest point of the device according to the invention via a gap between two of the rollers.
  • the rollers can end immediately after the narrowest point of the rotationally hyperbolic space. They are then attached to the outlet-side annular frame by means of rods which represent a continuation of the longitudinal axis of the rollers.
  • FIGS. 1 to 5 Examples of possible embodiments of the device according to the invention are shown in FIGS. 1 to 5.
  • FIGS. 1 to 5 mean the axis of rotational symmetry of the space serving for compression, which is enclosed by the rollers 2.
  • 3 is the body to be compressed, 4 the ring-shaped frame on the input side of the device, 5 that on the output side. 6 represents the drive of the rollers 2, 7 is the roll of packaging material 9, which is fed to the body 3 via deflection rolls 8 and via the braking device 10.
  • 11 is the transport device for removing the body 3, which is equipped with rollers 12 for absorbing the rotary movement, and 13 denotes the shaft stubs on the output side, which can be extended according to a variant of the device according to the invention.
  • FIG. 1 is a longitudinal section through a device according to the invention at the point marked A-A in FIG. 2.
  • Figure 2 is a cross section of the same device at the narrowest point of the tapered space. Its position is designated B-B in FIG.
  • the body 3 is drawn as if it were transparent.
  • the annular frames 4 and 5 are rigidly arranged, i. H. that the body 3 must be freely rotatable. In this embodiment, it is not itself stored, but is instead replaced by an independent device suitable for this purpose, which is not shown in FIG. B. by a mandrel that is mobile, in which he z. B.
  • Figure 3 shows a section in plane C-C in Figure 1.
  • the ring-shaped frames 4 and 5 are not shown adjustable in FIG. 1, so that in this embodiment a change in the angle alpha would not be possible. This embodiment was selected for the figure 1 for reasons of clarity.
  • the devices which are necessary to make one of the frames 4 or 5 so that they can be varied within the range according to the invention by setting any angle alpha within the range according to the invention are familiar to any person skilled in the art.
  • FIG. 4 and 5 illustrate an embodiment in which the body 3 can not perform a rotational movement, so that it is necessary to achieve the effect according to the invention that the annular frames 4 and 5 are rotatably mounted on two pairs of rollers 14. They must also be rigidly connected in order to be able to carry out a synchronous rotary movement in the same direction as the rotary movement of the individual rollers 2.
  • 15 is the drive of the frames 4 and 5, 16 are the means for preventing the rotational movement of the body 3.
  • FIG. 5 is a section at the point designated D-D in FIG. 4.
