Definitions

  • the invention relates to a method for the continuous low-tension wet treatment of a textile web according to the preamble of claim 1.
  • the invention also relates to a device for carrying out the new method.
  • DE 36 19 310 C2 describes a device for carrying out a dwell treatment of textile webs during a wet treatment process.
  • the web lying in a folded position on a conveyor, is guided through a tub filled with liquid.
  • a second conveyor which is arranged above the first conveyor, prevents the goods from floating.
  • the conveyors each have a downwardly inclined inlet section and a rising outlet section, so that the goods traverses a V-shaped path.
  • the invention has for its object to improve the method from which the preamble of claim 1 is based so that the goods move without a driven conveyor at the desired speed and are prevented from floating. It is also part of the task to create a device that is suitable for carrying out the new method.
  • the first part of the problem is solved by the characterizing features of claim 1, the second part by the features of claim 7.
  • a feed roller 2 for a web 3 to be treated is mounted in a frame (not shown) above a horizontal channel 1 with a rectangular cross section at one channel end.
  • Dispensing troughs 4, 5 are arranged on both sides of the vertical plane of the goods, which have overflow edges for the treatment liquid at the same height on the sides facing one another.
  • Connected to the overflow edges are the upper edges of two inclined baffles 6, 7 which are arranged in mirror symmetry with respect to one another and which enclose an inlet shaft tapering downwards.
  • the inlet-side end wall 8 of the channel 1 is slightly inclined.
  • At the other end of the canal is one near the canal bottom Deflection roller 9 attached.
  • a take-off roller 10 is mounted at a low height above the channel 1 in a frame, not shown.
  • a control bracket 12 is suspended in a pendulum manner on a joint 11 mounted just above the channel 1, consisting of two lateral arms and a round body 13, which at the lower end of the channel almost to the bottom of the channel 1 reaching arms is attached and extends substantially across the width of the channel 1.
  • the frame consisting of the arms and the round body 13 is covered with a net of wire or the like which is not visible in the drawing.
  • the channel 1 is separated from a chamber 15 by a height-adjustable overflow weir 14.
  • the chamber 15 is connected to the suction side of the circulation pump 16 by a line 17.
  • the circulating pump 16 is connected via a setting valve 18 and a line 19 to the induction channels 4, 5, which are supplied with liquid via a line 20 shown schematically.
  • the channel 1 is provided with a cover 21 which adjoins the induction channel 5 on the inlet side and has an edge 22 which is immersed in the liquid and is adjacent to the control bracket 12 on the outlet side. Between a partition plate 23, which is connected to the bottom of the induction channel 5 and is also immersed in the liquid, and the edge 22, the surface of the liquid is covered with freely floating balls 24.
  • the inlet area and outlet area are free of floating objects.
  • smooth intermediate walls are arranged on both sides in parallel to the side walls, which are not visible in the drawing.
  • the partitions are on guides that go above the liquid level are attached, displaceable transversely to the conveying direction.
  • the incoming spread web 3 is conveyed vertically downward via the feed roller 2, into the funnel-shaped inlet shaft located between the guide plates 6, 7 and there through liquid which flows uniformly downwards over the guide plates 6, 7 , flushed into channel 1 from above.
  • a loosely folded packing layer 25 which floats in the liquid and is prevented from floating by the balls 24 floating on its surface.
  • the formation of a relatively ordered packing layer 25 is favorably influenced by the inclined end wall 8.
  • a metered amount of liquid is continuously fed into the dispenser boxes 4, 5.
  • a flow rate is set in channel 1 in accordance with the amount of liquid supplied. The amount of liquid supplied is selected according to the invention so that the flow rate in channel 1 corresponds to the rate at which the loosely folded goods are to be conveyed.
  • the packing layer 25 formed from the goods hovers in the liquid essentially without touching the edge and therefore moves at the same speed.
  • the friction between the packing layer 25 and the balls 24 is so low that it causes no significant difference in speed between the liquid and the goods.
  • the initially relatively orderly packing layer is partially disturbed during the run, especially when the treatment liquid is approximately at boiling temperature, there are no entanglements or dislocations that hinder the withdrawal.
  • Under the control bracket 12, which controls the take-off speed of the goods the goods are pulled out of the packing layer 25 and removed in the spread-out state via the take-off roller 10.
  • the speed at which the goods are removed is set so that the length of goods stored in the packing layer 25 remains constant. This ensures that the dwell time is the same for each length element of the goods.
  • a belt 26 runs around in the lower part of the channel 1, preferably a sieve belt.
  • the band 26 extends almost over the full width of the channel 1 and is guided over deflection rollers 27, 28, one of which is arranged under the inlet-side end wall 8 and the other under the control bracket 12.
  • the upper run of the band 26 is supported by rods 29.
  • the pulley 28 is provided with a variable-speed drive, not shown. The speed is set in operation so that the upper run moves at the same speed as the packing layer 25.
  • the function of the belt 26 is therefore essentially to eliminate any friction between the goods and the bottom of the channel 1. Such a band is therefore only to be provided if it cannot be ruled out that the packing layer 25 touches the bottom of the channel 1.
  • a heater 30 is arranged between the two strands of the belt 26 and is connected on the inlet side to a steam line 31 and on the outlet side to a condensate drain 32.
  • the circulation circuit of the treatment liquid comprises a filter 33 which is mounted in the chamber 15 before the line 17 is connected.
  • the bottom of the channel 1 is provided with a plurality of depressions arranged at uniform intervals. These have the shape of channels 34 with a semicircular cross section and extend over the width of the channel 1.
  • a paddle 35 is arranged in each channel 34, consisting essentially of a shaft 36, which by radial struts 37 with rods 38 arranged parallel to the shaft connected is.
  • the shaft 36 is rotated in operation by a drive, not shown.
  • the envelope surface of the cylinder space covered by the paddle 35 projects partially beyond the bottom of the channel 1.
  • the rod 38a located at the top has a movement component which in the 12 o'clock position corresponds approximately to the speed at which the packing layer 25 moves in the direction of the arrow 39.
  • the goods in the packing layer 25 are gently folded over.
  • the treatment liquid flowable flexible cloth 40 for. B. a coarse-mesh, mesh-like fabric.
  • a perforated film or the like can also be used instead of a cloth. The cloth 40 prevents the goods from jamming or getting caught on the paddle 35.
  • the exemplary embodiment according to FIG. 4 is equipped with a plurality of rammers 41, 42, 43 distributed over the length of the channel 1.
  • rammers 41, 42, 43 distributed over the length of the channel 1.
  • three different designs of the rammer are shown, as well as three different drives. This representation was chosen in order to be able to illustrate the different variants on the basis of a single figure.
  • the tamper 41 has the shape of a rectangular cage with a flat, horizontal bottom, which, like the side parts, has a flow-permeable structure.
  • the tamper 41 consists, for. B. from a rigid wire mesh. It can be raised and lowered in a guide 44 between an uppermost position in which the bottom is only a little below the liquid level and a lowermost position in which it is immersed up to about half the height of the liquid level. Due to the grid-like structure, the liquid displacement is very low. The flow is hardly disturbed.
  • the lifting movement of the rammer 41 only causes the goods to be rearranged in the packing layer 25.
  • the stroke movement takes place by means of a crank mechanism 45. The stroke can be varied by radial displacement of the crank pin 46 on the crank disk 47.
  • the crank drives 45 of a plurality of tamper 41 can be driven by individual motors or by a common motor via chains or V-belts.
  • the tamper 42 has an inclined bottom which rises in the conveying direction 39. As a result, a lateral component acts on the goods during the lifting movement, which favors the folding of the goods.
  • a double-acting cylinder 48 is provided as the drive.
  • the pressure medium is preferably controllable so that upward movement and downward movement can take place at different speeds. A rapid downward movement and a slow upward movement of the rammer 42 are advantageous.
  • the stroke is variable in a preferred embodiment, e.g. B. with the help of adjustable stops, not shown.
  • the bottom 49 has a curvature, the curvature of which is adapted to the diameter of the balls 24.
  • the curvature prevents the balls 24 located under the tamper 43 from moving sideways. Therefore, the balls 24 are pressed deeply into the treatment liquid by the tamper 43 during its downward movement, so that they act as a displacement body.
  • the tamper 43 itself is arranged and dimensioned so that it does not submerge and does not come into contact with the goods.
  • An inflatable air bellows 50 with return spring 51 is provided as the drive.
  • the distance between two adjacent rammers is usually between 0.5 m and 2 m, so that the device has a maximum of six to eight rammers.
  • the stroke frequency of the rammers 41, 42, 43 is between about 10 and 60 strokes / min. It is advisable to use the different tampers of a device with different frequencies or - at the same frequency - operate with irregular phase shifts to avoid resonance phenomena in the form of standing waves.
  • the goods By heating the floor to boiling temperature, the goods are buoyed by rising bubbles which adhere to the goods. Due to the buoyancy, any contact between the packing layer 25 and the bottom of the channel 1 and thus also any friction is excluded.
  • Above the floor distributed across the width of the channel, are a number of liquid or steam lines 53 which, starting at the goods inlet, extend in the longitudinal direction of the channel 1 and extend into the vicinity of the control bracket 12.
  • Nozzles 54 are attached to the individual liquid or vapor lines 53 at regular intervals. These form several rows running in the transverse direction. They aim obliquely upwards into the packing layer 25 so that the blowing direction has a component in the conveying direction 39.
  • Corresponding liquid or steam lines 55 with nozzles 56 directed obliquely downward into the packing layer 25 are arranged above the layer formed from the balls 24.
  • the nozzles (54, 56) can be activated continuously or periodically.
  • the bottom of the channel 1 is provided with a plurality of transversely running flat channels 57 which are distributed uniformly over the length.
  • the hoses 58, 59 are connected to a steam line 60 and each connected to a condensate drain 61.
  • the tube 58 is shown in FIG. 6 in the inflated state. In this condition in channel 1 it reduces the flow cross-section to less than half.
  • the goods are rearranged in the packing layer 25.
  • the rearrangement is supported by the simultaneous increase in the flow velocity in the reduced cross section over the hose 58.
  • the hose 59 is shown in the state during the emptying. Without the supply of steam, the steam condenses in the tubes, which is why the tubes 58, 59 lie limply in the channels 57 without influencing the movement of the packing layer 25.
  • the distances between two adjacent hoses 58, 59 correspond approximately to the distances of the rammers 41, 42, 43 specified in connection with FIG. 4. Corresponding distances also apply to the other devices for turning over the goods.
