Definitions

  • the invention relates to a spreader for tubular goods with a frame to which at least one roller arrangement is fastened on both sides on the right and left, each having an outer guide roller around which the tubular fabric is placed and which hold the tubular fabric wide, with the tubular fabric on the guide roller a drive roller driven for rotation abuts, which drives the guide roller via a frictional connection and thereby transports the tubular goods, and with at least one support roller which receives the tension exerted by the tubular goods on the guide roller.
  • DE-OS 28 23 978 describes a spreader for tubular goods, in which a pair of guide rollers is provided on the inside of the spreader, which are driven by a common drive roller, which, similar to the European patent application discussed above, relates to tubular goods the outside of the guide rollers.
  • a pair of guide rollers is provided on the inside of the spreader, which are driven by a common drive roller, which, similar to the European patent application discussed above, relates to tubular goods the outside of the guide rollers.
  • the tension exerted by the tubular goods on the guide rollers during operation interrupts the frictional and non-positive connection between the rollers.
  • EP-A-0 204 660 which describes a spreader with endless transport belts which are releasably in drive engagement with feed rollers. Measures are provided here in order to be able to change the width of the spreader from the outside unhindered when the tubular material is passing through.
  • the invention is based on a spreader with the features mentioned, the task of designing it so that the spreader transports the tubular goods properly, it should also be easily adjustable to different tubular goods widths if necessary.
  • the invention is characterized in that the drive roller, based on the frame, on the inside of the Guide roller rests and is supported by the support roller, which rests on the side facing away from the guide roller on the circumference of the drive roller.
  • the tension exerted by the tubular goods on the guide roller thus at most increases the frictional and non-positive connection between the driving roller and the guide roller, so that the tubular goods are transported continuously and without stagnation through the spreader, namely over their entire surface located in the spreader.
  • the guide roller and the support roller lie in one and the same plane, so that warping by angularly acting support rollers, as in the generic state of the art, is also no longer possible.
  • the support roller is at right angles to the direction of transport of the tubular goods behind the guide roller.
  • an arrangement is preferred in which two of the guide rollers are provided at a distance from one another, behind which the support roller is arranged in a symmetrical arrangement.
  • you assign a single support roller to the two guide rollers and the two guide rollers ensure a particularly smooth and wrinkle-free transport of the web through the spreader.
  • the spreader according to the invention is preferably used in a machine with which the tubular goods are mercerized, specifically at the entrance to such a machine.
  • roller arrangements are provided one behind the other on both sides of the frame in the transport direction of the tubular goods. This measure, which is known per se, brings about a particularly smooth, unimpeded and continuous transport of the tubular goods through the spreader.
  • the drive rollers it is preferred if two of the drive rollers are provided on both sides of the plane defined by the guide roller and the support roller, the axes of rotation of which run parallel to this plane. So you choose an arrangement of the drive rollers perpendicular to the support and guide rollers, so that the guide rollers are supported on the support roller over the circumference of the drive rollers.
  • An important embodiment of the invention is characterized in that a separate drive for the drive rollers of this side is provided on each side of the frame. This makes it much easier to change the working width of the spreader.
  • rollers For the non-positive and frictional engagement of the rollers with one another, it is preferred if the rollers have inclined surfaces on their circumferences for the frictional force transmission between the rollers.
  • the spreader shown also called flat spreader, is arranged on the inlet side of a mercerizing machine. See Fig. 1. It consists of a portal-shaped frame 1, which is substantially U-shaped, the two U-legs are formed by mutually spaced mutually spaced frame sides 1a and 1b. The two sides of the frame 1a, 1b are connected to one another by a crossbar 2.
  • a torsion frame 3 is arranged, which has an adjustment drive for width adjustment.
  • a motor 4 is arranged on one side, which rotates a spindle 5 arranged in the interior of the torsion frame 3 in a manner not shown in detail.
  • each flat spreader 7a, 7b a spindle nut is arranged (not shown), which is penetrated by the spindle 5. By rotating the motor 4, the flat spreader 7a, 7b are thus adjusted in the arrow directions 6.
  • the adjustment is made so that the flat spreader 7a, 7b are always exactly parallel to each other.
  • the flat spreader bars 7a, 7b are connected via a bearing point 28 to a connecting plate 10, the two connecting plates being articulated to one another in a further bearing point 29.
  • the connecting tabs thus form a positive guide for an ascending web 11, so that the web is prevented from sagging in this area between the flat spreader 7a, 7b or forming a belly.
  • the web 11 is transported in the direction of arrow 9.
  • Fig. 1 shows the large adjustment range of the connecting frame 3 where it is shown that the flat spreader 7a, 7b can be moved up to a position 7a ', 7b', a minimum width of z. B. 270 mm can be achieved and a maximum fabric width according to the design conditions. It is therefore important here that the minimum width of the goods can be achieved because the telescopic rods described above and belonging to the prior art can be dispensed with. The minimum width of the goods is actually only limited by the fact that in the retracted position (retracted position) the two flat spreaders 7a, 7b lying opposite one another touch.
  • each flat spreader 7 has a chain drive 12 carries, with a chain drives pulleys 18 over pulleys and guide rollers (see Fig. 2).
  • Each flat spreader 7 has a bearing plate 14 lying one above the other at a distance from one another, three rollers being rotatably and non-displaceably arranged on the bearing plate, namely guide rollers 15, 16, and a support roller 17.
  • a drive roller 18 engages in the space between the rollers 15, 16, 17, which is rotatably driven by the chain drive 12 via a drive shaft and an associated chain wheel.
  • the chain drive 12 is part of a bearing frame 21a, 21b, this bearing frame 21 being fixedly arranged with the said spindle nut on the connecting frame 3.
  • the sole connection between the storage frame 21 and the wide, adjustable flat spreader 7 is made solely via the rotatably driven drive rollers 18.
  • the web is transported in such a way that the web 11 runs over non-driven guide rollers 13 over the flat spreader 7, is guided there over the rollers 15, 16, 17 and because the drive roller 18 in each case into the space between the guide rollers 15, 16, 17 there attacks the non-positive drive of the web via the non-directly driven rollers 15, 16, 17.
  • Fig. 2 shows the side view of the spreader according to Fig. 1, seen from the right side, whereby it can be seen that the web 11 runs over the relatively narrow connecting tab 10 on the flat spreader 7.
  • the web is deflected around the deflection roller 30, runs here via a further roller 31 (see FIG. 3), is steered upward there in the direction of arrow 34, runs there in the direction of arrow 35 around an upper deflection roller 33 over and then runs over a lower deflection roller 32, where it is in turn deflected.
  • the web 11 thus runs in a meandering shape through a treatment bath, not shown.
  • the chain drive 12 consists of a motor 22 which drives a drive wheel 26, via which the chain is guided in a closed circuit via chain tensioning wheels 25 and deflection wheels 27. It can also be seen that the shaft 19 of the drive roller 18 is driven by the chain drive.
  • machine part 1, 2 is connected to the treatment unit behind it via further cross members 23, 24.
  • Fig. 4 shows schematically the top view of a bearing plate 14, wherein it should also be pointed out that parallel to the plane of FIG. 4 below the rollers 15 to 18 shown, an exactly symmetrical arrangement is provided, as is the case, for. B. also from FIG. 6, where you can see that a total of two opposing drive rollers 18 in a bearing plate 14 engage in mutually facing spaces between assigned rollers 15 to 17.
  • the drive roller 18 is always at a constant distance from the underlying rollers 15, 16, 17 arranged perpendicular to it, this distance being fixed and can be changed depending on the thickness of the goods to be transported.
  • the goods are transported in the direction of arrow 46.
  • the inclined surfaces 36, 37 of the rollers lie opposite assigned inclined surfaces 38, 39 of the drive roller 18. in that contact surfaces 41, 42, 43 are formed.
  • the drive roller 18 includes a relatively short inclined surface 39 with an associated inclined surface of the roller 17, the two inclined surfaces being exactly parallel to one another and being at a mutual distance from one another.
  • the tip 40 of the drive roller 18 is rounded in order to avoid a sharp kinking of the goods.
  • a long inclined surface 38 adjoins the tip 40, which is opposed by an associated contact surface 41 of the guide roller 15.
  • An associated contact surface 42 of the roller 17 is assigned to the upper inclined surface 39.
  • zones 39, 42 and 38, 41 ensures that the material web is non-positively transported in the direction of arrow 46.
  • the flat spreader 7 is rounded on its front part 45, in order to avoid a sharp bend in the material web 11.
  • a recess 47 is provided (see FIGS. 4 and 5) in which the guide rollers 15, 16 are sunk.
  • FIG. 6 shows a representation rotated by 90 °, namely the top view of the arrangement in FIG. 4 in the direction of arrow VI, wherein it can be seen that the recess 47 is provided in the bearing plate 14 in exactly symmetrical opposite relationship.
  • Fig. 7 shows a section along the line VII-VII through the flat spreader 7 with the bearing plate 14. It can be seen that the opposing guide rollers 15 are rotatably mounted in the flat spreader 7 via ball bearings 49 and the guide rollers 15 by a screw 50 are secured.
  • the bearing plate 14 which in turn carries a ball bearing 48 in which the two support rollers 17 are rotatably mounted.
  • Fig. 8 it can be seen that further guide rollers 13 are rotatably mounted in the flat spreader 7 via corresponding bolts 51 in order to ensure low-friction transport of goods.
