Definitions

  • the system known from the prior art consists in transferring, by means of the same circulation pump of the dyeing bath of the machine which delivers the bath through the exchanger unit to the Overflow funnel or to the Jet, all the bath of a dyeing machine to the following, or preceding, dyeing machine, until the last machine operating in the parallel configuration receives the dyeing bath from the first machine of the cascade, and vice-versa, and so on, in continuous, throughout the dyeing time.
  • the dyeing machines for example, a series of four machines like those which are mentioned in the example set forth in the following, are connected with one another by means of a complex system of large diameter pipes, i.e., having a same diameter as of the flow or Jet duct, on which 26 automatic valves are installed in order to control the bath circulation according to the required path by the selected operating configuration; each valve is provided with a pneumatic, double-effect servocontrol unit which causes the valve to rotate by 90°. in both directions; each servocontrol unit must be provided with two limit switches in order to check that the valve is actually opened or closed, consequently with a total number of 52 limit switches. Summing-up, in order to allow a known system consisting of four machines in series to operate in parallel mode, additionally to the inherently quite complex piping system, 26 valves, 26 servocontrol units and 52 limit switches are required.
  • a flow configuration interconnecting first and second textile dyeing machines such that dye circulated through the first dyeing machine is homogeneously intermixed with dye circulated through the second dyeing machine is disclosed in US-A-5 228 318.
  • the present invention consists in having separated the loop for mixing the bath of the several machines from the loop used for circulating the dyeing both inside each machine and in having used, for circulating the bath from a dyeing machine to another dyeing machine, a suitable pump of reversible type and having simply connected each tank of each dyeing machine to the tank of the immediately downstream dyeing machine by means of two pipes, wherein the one pipe is installed in a low position at tank bottom level, on which the pump and a valve are installed; and the other pipe being installed slightly under the maximal level reached by the dyeing bath inside the tank, and on which a second valve is installed.
  • the circulation pump for the dyeing bath of each dyeing machine is used in this case only to circulate the dyeing bath inside the same machine, by collecting it from the bottom of the tank and supplying it, through the exchanger unit, to the Overflow funnel or Jet.
  • the dyeing bath of each dyeing machine is collected by the pump from the bottom of the tank and is sent to the tank of the downstream dyeing machine, so that on this second machine the level of the dyeing bath contained in its tank rises and, through the second, higher-level pipe, overflows into the tank of the preceding dyeing machine, and so forth, according to the desired operating combinations, as it is disclosed in greater detail in the following.
  • This procedure is performed during a certain time in a direction and is then reversed during a same time period, because the pumps are of reversible type.
  • (1), (2), (3) and (4) are the four machines which constitute the set of dyeing machines in question, suitable for operating in parallel.
  • Each of them is equipped with a pump (P1), (P2), (P3) and (P4) which causes the dyeing bath of the respective machines to circulate, i.e., collects the dyeing bath from the tank bottom and delivers it, after flowing through the exchanger unit (S), to the Overflow funnel or Jet nozzle of each dyeing machine, in known way.
  • P1 a pump
  • P2 P2
  • P3 the exchanger unit
  • P4 which causes the dyeing bath of the respective machines to circulate, i.e., collects the dyeing bath from the tank bottom and delivers it, after flowing through the exchanger unit (S), to the Overflow funnel or Jet nozzle of each dyeing machine, in known way.
  • the dyeing machine (1) is connected with the dyeing machine (2) by means of a pipe (5) installed at the level of the tank bottom portions of said dyeing machines, on which pipe (5), the pump (M1) and the valve (V1) are installed; and by a second pipe (6) positioned slightly under the maximal level which will be reached by the dyeing bath inside the tanks, and on which the valve (V4) is installed.
  • the dyeing machine (2) is connected with the dyeing machine (3) by means of a pipe (7) installed at the level of their tank bottom portions, on which pipe (7) the pump (M2) and the valve (V2) are installed; and by a second pipe (8) positioned slightly under the maximal level which will be reached by the dyeing bath inside the tanks, and on which the valve (V5) is installed.
  • the dyeing machine (3) is connected with the dyeing machine (4) by means of a pipe (9) installed at the level of the tank bottom portions of said dyeing machines, on which pipe (9), the pump (M3) and the valve (V3) are installed; and by a second pipe (10) positioned slightly under the maximal level which will be reached by the dyeing bath inside the tanks, and on which the valve (V6) is installed.
  • the pumps (P1), (P2), (P3) and (P4) are kept operating as it normally occurs in Overflow or Jet dyeing machines operating on an individual basis, whereas the corresponding pumps (M1), (M2) and (M3), performing the task of homogenizing the dyeing bath by alternatively transferring it in both directions from each dyeing machine to the adjacent machine arranged in parallel to it, are caused to operate, or not according to the preselected parallel configuration as a function of the amount of fabric to be dyed into a determined colour.
  • the present Applicant could find that according to this system, the dyeing bath contained inside a dyeing machine is caused to flow cyclically to another dyeing machine, and from each dyeing machine to all other dyeing machine, and a perfect homogenizing of the dyeing bath is thus obtained even in the case of a configuration with all machines being connected in parallel, with the dyeing bath being throughly mixed and with a surely homogeneous fabric dyeing being obtained.
  • FIG 4 discloses the case when all machines operate on an individual basis.
  • pumps (M1), (M2) and (M3) do not operate and valves (V1)-(V4), (V2)-(V5) and (V3)-(V6) are closed.
  • FIG. 5 shows the case when dyeing machines (1) and (2) operate in parallel and machines (3) and (4) operate individually.
  • valves (V1)-(V4) are open, all other valves are closed and pump (M1) is running.
  • Figure 6 discloses the case when machine (1) and (2) operate individually and machines (3) and (4) operate in parallel. Consequently, in this case pumps (M1) and (M2) will be stationary, valves (V1)-(V2) and (V4)-(V5) will be closed, and valves (V3)-(V6) will be open and pump (M3) will be running.
  • FIG. 7 shows the dyeing machines as being in a configuration of 2x2 in parallel.
  • valves (V1)-(V4) will be open, pump (M1) will be running, valves (V2)-(V5) will be closed, pump (M2) does not operate, valves (V3)-(V6) will be open and pump (M3) will be running.
  • FIG 8 shows the machines (1), (2) and (3) as operating in parallel, with machine (4) operating individually.
  • valves (V1)-(V4) and (V2)-(V5) are open, pumps (M1) and (M2) are running, valves (V3)-(V6) are closed and pump (M3) is stationary.
  • Figure 9 shows all four machines as operating in parallel.
  • the internal diameters of the pipes can be reduced because, while the dyeing bath from the upstream dyeing machine is flowing towards the immediately downstream dyeing machine, the dyeing bath from said immediately downstream dyeing machine is being simultaneously delivered back to the upstream dyeing machine owing to the effect of dyeing bath level increase.
  • the electronic control system is much simpler, because it must control only 6 valves and 12 limit switches with a simple logics which must check only three well-defined combinations which are always the same.
