Definitions

  • the invention relates to a method for laboratory dyeing e.g. Carpet patterns by applying a defined amount of color to the visible side of the pattern and transporting this pattern into a laboratory steamer in which the pattern is moved.
  • the invention has for its object to develop a method and an apparatus for performing this method with which the same conditions can be achieved on the laboratory color scale as in continuous production, without the need for an expensive continuous laboratory dyeing system to be set up in the laboratory.
  • the sample piece is connected to form a hose or stocking open at least on one side. This sample piece is then to be kept in constant motion both during the dyeing job, during transport into the damper and in the damper itself.
  • the advantage of this measure is clear. Due to the idea of not coloring the sample flat, but connecting it to form a tube and then rotating this tube continuously during the subsequent treatments, this means that a continuous dyeing can be carried out on this finite sample.
  • the device for performing this method consists in a simple manner of a lever, at the upper free end of one Dyeing roller rotatably mounted and which can be moved from the color position into the damping position.
  • a steaming hood is then expediently held lowerable over the dyeing roller.
  • Such a damper is advantageously small in its outer dimensions. It can always be under steam without loss of steam and can be quickly made available for a new color fixing process.
  • the dyeing roller is overhung on the lever and a dyeing knife is arranged above the dyeing roller in the ink position of the lever, which is connected to an inking device that works according to the pouring principle.
  • the lever is advantageously designed as a toggle lever and held in a swivel joint at the end opposite the dyeing roller.
  • the toggle lever should enclose an angle that is not much more than 90 °, so that when the toggle lever is arranged in the damping position, the lower leg is arranged approximately horizontally, on the other hand, the leg of the lever with the coloring roller plumb into the bottom Damper hood protrudes.
  • the ink application device is cleaned before a new dyeing process. This cleaning can also be carried out automatically by the actuating device without wasting time during steaming.
  • the dyeing process should be completed in a short time in the method according to the invention or the device considered to be advantageous for carrying out this method in order to prevent over-dyeing, it is necessary to abruptly end the ink application.
  • This liquor collecting tray is not only advantageous for ending a paint application process, but also for carrying out the mentioned cleaning process of the inking device, so that the water necessary for cleaning does not run off in the direction of the dyeing roller, but can be drained off via a separate branching device.
  • the separation of the inking device and dyeing roller by the liquor collecting plate is also advantageous for determining the exact amount of ink applied and possibly also the color.
  • the ink liquor flows back normally over the squeegee, but not over the inking roller, but over the liquor collecting plate. This possible cycle can continue until the desired dyeing conditions are met. Then the collecting tray is pulled back and at the same time the ink head is lowered.
  • the inking device is designated by 1 overall with the doctor blade 2 running obliquely downwards, below which the inking roller 3 is rotatably arranged.
  • the dyeing roller 3 is arranged on a toggle lever 4, which is about the swivel joint 5 in the position shown in dash-dotted lines downward in the direction of the arrow 6 is relocatable.
  • the movement of the toggle lever 4 from the dyeing position I into the damping position II is controlled via the pressure piston cylinder unit 7, which is articulated on the stand 8 of the paint applicator 1 on the one hand and on the other hand on the toggle lever 4.
  • the lower leg 9 of the toggle lever 4 is arranged horizontally in the damping position II, while the upper leg 10 of the toggle lever 4 is inclined upwards but slightly forward. These two legs 9, 10 thus enclose an angle slightly greater than 90 °, which also results in a stable position of the toggle lever 4 in the damping position II.
  • the dyeing roller 3 at the upper end of the upper leg 10 of the toggle lever 4 is connected to a motor, not shown, which drives the roller both in the dyeing station I and in the steaming station II continuously.
  • the paint applicator 1 shown at the upper end of the stand 8 is described in detail in DE-35 22 320 A1.
  • the paint applicator 1 is pivotally mounted about the hinge 11 to z. B. at the end of the dyeing process, the paint applicator 1 can pivot counterclockwise.
  • a liquor collecting plate 12 which is arranged below the ink application device 1 and is displaceably mounted in the direction of arrow 13, is pushed below the drip edge of the squeegee 2, so that the ink liquor flowing off from the ink application device 1 via the squeegee 2 slides off the fleet collecting plate 12 can be collected and derived in the color return.
  • the movements of the upward swiveling of the ink application device 1 and the advancement 13 of the liquor collecting plate 12 are coordinated below the drip edge of the doctor blade 2 by a sensible mechanism.
  • a further collecting plate 14 is arranged beneath the dyeing roller 3, but in any case it is intended to collect the dyeing liquid flowing down from the sample piece 15 and to discharge the cleaning liquid and to discharge it via a line 16 into a collecting container.
  • a damper is also arranged on a stand 17 on the side next to the stand 8 with the paint applicator 1.
  • the damper consists of a hood 18 open at the bottom, which on the Stand extends in the direction of the paint applicator 1 and is held from top to bottom.
  • the damper rear wall 19 facing away from the dyeing position 1 ends with its lower edge 20 higher than the three other walls 21-23.
  • the width of the damper hood adjoins this rear wall 19 via a steam suction channel 24, which sucks excess steam introduced into the damper.
  • a sufficient steam atmosphere for the dyeing conditions is always in the damper hood 18.
  • a tube is placed over the dyeing roller 3, which is designated 15 in the drawing.
  • the material of this sample is cut out of the web material, which is to be treated later in the continuous process, and is made into an endless sample by a seam to this tube 15.
  • the dyeing roller 3 is cantilevered on the toggle lever 4, so that the hose 15 can be slipped over the dyeing roller easily.
  • ink liquor now flows via the ink application device 1 onto the sample piece 15, which - as said - runs over the dyeing roller 3 as in continuous operation.
  • the liquid application process stops by means of the collecting plate 12 and the toggle lever 4 is pivoted via the pressure piston cylinder unit 7 from the dyeing position I into the damping position II, which is shown in the drawing with a dash-dotted line.
  • the damper hood 18 lowers into the damping position, likewise drawn with dash-dotted lines, so that the dyeing roller 3 arranged at the upper end of the upper leg 10 of the toggle lever 4 is arranged in the middle of the steam atmosphere of the damper hood 18. Since the dyeing roller also rotates in the steaming chamber, the hose 15 is also moved forward in the same transport direction during steaming, so that the same conditions prevail here as in continuous operation.
  • the damper hood is again raised to the position drawn with solid lines, the colored tube 15 can be pulled off the dyeing roller 3 and the toggle lever 4 can be pivoted back into the dyeing position 1. A new dyeing process can kick off.
  • an actuating device 25 which is only indicated in the drawing and consists of an electronic unit, is provided.
  • a push button 26 By pressing a push button 26 "dyeing" the dyeing and steaming process runs automatically with all necessary process conditions. It consists first of all of the drive of the dyeing roller 3, the application of the color provided via the inking device 1 to the circumference of the sample 15 and the termination of the ink application, which consists of swiveling the inking device 1 upwards about the swivel joint 11 and advancing the fleet Collecting plate 12 in the direction of arrow 13. With the dyeing roller 3 still rotating, the toggle lever 4 is pivoted into the dyeing position 2 by activating the pressure piston cylinder unit 7.
  • the damper 18 lowers over the inking roller 3, which rotates further, whereby the damping process begins. After a certain time, which can also be set on the actuating device 25, the damping process is ended, whereupon the damper hood 18 automatically moves up again. After pivoting the toggle lever 4 back into the dyeing position, a new dyeing process can now begin. It is advisable to carry out a cleaning cycle on the ink application device during this steaming process. This consists in that a cleaning liquid such as water now flows over the squeegee 2 instead of the paint previously applied to the sample 15. This not only cleans all the passages in the inking device 1, but also the doctor blade and the other parts of this dyeing device.
  • the necessary water flows through the liquor collecting plate 12 or the collecting plate 14 into a corresponding collecting container.
  • the liquor collecting plate 12 is also automatically moved back again - in the opposite direction of the arrow 13 - with which the ink application device 1 can also pivot clockwise again into the position drawn with a solid line.
