Definitions

  • the present invention generally relates to a conveyor drive fabric dyeing machine equipped with seam detector that is capable of monitoring and recording the movement of fabric and detecting the leading end of fabrics, the cycle time, and the number of cycles of circulation of the fabric in order to control a dyeing process.
  • FIG 1 is a schematic view illustrating the dyeing circulation of fabric in a conventional dyeing machine.
  • the operation principle is that dye liquid F is pressurized by a pump D2 and passes through a heat exchanger C (for increasing or decreasing temperature) into a nozzle A4 to generate a jetting or overflowing liquid flow and then returns to a fabric accumulation tank A 1 of a dyeing machine A.
  • Fabric B is driven by a fabric roller A3 (or alternatively using no fabric roller) into the nozzle A4 so that the fabric B is driven by the force induced by the jetting or overflowing liquid flow from the nozzle A5 to circulate.
  • Dye liquid and chemical agents are supplied from a service tank E and pressurized by a pump D1 to inject into the dyeing machine A.
  • the dye liquid F and the fabric B undergoes a process including heating, temperature-holding, cooling achieved with the heat exchanger C to have the dye absorbed by the fabric and achieving the effects of scouring, dyeing, and water washing.
  • Uniformity of dyeing is determined by the number of cycles of circulation of the fabric during the dyeing process, namely the number of interactions between the fabric B and the dye liquid in the nozzle A4 and the dyeing tube A2.
  • a great number of cycles of circulation indicates a great number of interactions and thus better uniformity of dyeing, as well as the extent of water rinsing and dyeing fastness.
  • FIG 2 which shows a curve of a typical dyeing process employed in a conventional dyeing machine
  • the conventional dyeing machine uses "time" as a control unit (denominator) to carry out treatments of fabrics dyeing, including, in sequence, chemicals adding, heating, temperature holding, heating, temperature holding, cooling, water rinsing, chemicals adding, heating, temperature holding, cooling, and hot water rinsing.
  • Control is generally achieved with a computer or a programmable logic controller (PLC).
  • PLC programmable logic controller
  • the conventional dyeing machine uses "time" as a control unit, it generally takes the same amount of time to complete a dyeing process regardless the actual length or weight of the fabrics being dyed.
  • time in an actual dyeing process, due to the fabric that are being dyed having different weights or the thicknesses of the fabrics being different, the lengths of fabrics in each batch, each tube may be different.
  • the fabrics may be of the same type, adopting a dyeing process of the same amount of dyeing time is generally a waste of time.
  • the number of cycles of circulation is different.
  • British Patent GB 2 208 299 A discloses an arrangement for regulating the speed of circulation of a fabric through a treatment apparatus.
  • the arrangement comprises a winch that drives the fabric to move through the treatment apparatus.
  • no other mechanical device is included to help drive the fabric through the treatment apparatus.
  • a sensor is included to detect at least one magnetic marker. This is disadvantageous that the magnetic marker must be additionally attached to the fabric.
  • US Patent No, 6,085,555 discloses a palm-top fabric leading edge detector, which is arranged to detect a magnetic body attached to a leading edge of a fabric. This is similarly disadvantageous in that the magnetic body has to be additionally attached to the fabric.
  • JP H 04 100968 discloses a similar technique, in which a magnet has to be additionally attached to a fabric to be detected by two spaced sensors.
  • An object of the present invention is to overcome the problems occurring in a dyeing process of a conventional dyeing machine that uses time as a control unit so that the same amount of time is taken in carrying out the dyeing process regardless the actual lengths of fabrics that are dyed so that even though the dyeing time is identical, the results of the dyeing operations are different thereby leading to the problems of batch deviation or tube deviation, inconsistent fastness, poor reproductivity, and waste of time.
  • the present invention is made to change the way of control of the conventional dyeing machine by using the number of cycles of circulation of fabric as a control unit (denominator).
  • the horizontal axis of the plot shown in FIG 2 is changed from "time” to "number of cycles of circulation of fabric".
  • the dyeing process is controlled on the basis of the number of cycles of circulation of fabric.
  • the time required for the entire dyeing process is long; for a rope of fabric having a small length, the time required for the entire dyeing process is short.
  • the present invention provides a fabric dyeing machine according to claim 1.
  • the technical solution of the present invention is to arrange a conveyor in a machine body of a dyeing machine to forward the fabric that is in a circulating process in the machine body of the dyeing machine from the rear end of the machine body to the front end so that there is no need to use the floating or push force of a liquid flow or an air flow that is employed in the conventional dyeing machine to drive the fabric.
  • the speed of the conveyor is controlled with a controller, such as a computer or a programmable logic controller (PLC) to be in synchronization with the circulation speed of the fabric so that the circulation speed of the fabric is made stable and constant, making the time of each cycle of circulation identical.
  • a controller such as a computer or a programmable logic controller (PLC)
  • the present invention arranges a fabric seam detection device (seam detector) at a suitable location in the dyeing machine, whereby with signals output from the fabric seam detector by means of the use of the controller for example a computer or a programmable logic controller (PLC), the number of cycles of circulation of fabric can be identified and used as a control unit for the dyeing process.
  • the controller for example a computer or a programmable logic controller (PLC)
  • PLC programmable logic controller
  • the present invention provides a fabric dyeing machine equipped with seam detector, which comprises a machine body 1 in which a conveyor 2 is arranged for conveying a rope of fabric 3 from a rear end of the machine body 1 to a front end.
  • the fabric 3 is then driven by a fabric guide roller 4 into a nozzle 5.
  • Dye liquid 6 is pressurized by a pump 7 and subjected to temperature control by a heat exchanger 8 to be then sprayed from the nozzle 5 onto the fabric to induce a dyeing effect and also to drive the fabric 3 to enter a fabric guide tube to subsequently fall down to the conveyor 2 for being further conveyed to the front end of the machine body and the seam detector 10 is equipped to detect the seam or leading end of the fabric rope and count the cycles of the fabric circulation.
  • the effectiveness of dyeing is determined by the number of interactions between the fabric and the dye liquid in the nozzle and a dyeing tube A2.
  • the operation speed of the conveyor 2 is controlled by a control box 9 in order to be in synchronization with the circulation speed of the fabric and the speed can be adjusted as desired, but becomes a constant and fixed speed after being set.
  • the circulation speed of the fabric is fixed and the time required to go through a cycle of circulation is constant for each cycle.
  • the dyeing process is carried out in such a way that the number of cycles of circulation of the fabric is used as a control unit and control is carried out with a controller, such as a computer or a programmable logic controller (PLC) of the control box 9 in order to carry out the dyeing process illustrated in FIG 4 .
  • PLC programmable logic controller
  • the actual dyeing effect obtained with the fabric seam detection device included conveyor drive fabric dyeing machine is primarily and directly determined by the number of interactions between the fabric and the dye liquid in the nozzle and dyeing tube.
  • the essential factor is the number of cycles of circulation of the fabric, not the length of time (namely an absolute relationship being had with respect to the number of cycles of circulation, while a relative relationship is had with respect to time).
  • the degree of dyeing is different and the result of dyeing is also different, leading to issues of tube deviation, batch deviation, inconsistent fastness, and inconsistent reproductivity.
  • the number of cycles of circulation must be the same regardless the actual length of fabric dyed.
  • the time can be shortened correspondingly. This can shorten the time for the entire dyeing operation and since the number of cycles of circulation is the same regardless the length of the fabric, the degree of dyeing is the same and one hundred percent of reproductivity of dyeing can be achieved.
