Definitions

  • the present invention relates to a method and apparatus for controlling the flow of treatment fluid in a package dyeing machine.
  • Textiles such as yarn, thread, ribbon and the like are commonly wound onto large conical spools or bobbins to form packages for handling by textile treatment machines.
  • Textile treatment includes dyeing and also treating with substances other than dye, where the dye stuff or other treatment substance is diluted in water to give a treatment fluid or liquor.
  • a quantity of packages are loaded onto hollow spindles inside the kier of a treatment machine, the kier is filled with the treatment fluid, and the fluid is then passed through the packages using a fluid circulation system.
  • a pump drives fluid around the circulation system.
  • An inside-to-out flow path sends fluid up inside the hollow spindle, through perforations in the spindle wall and outwardly through the package, to the main volume of the kier.
  • An opposite, outside-to-in flow path forces fluid from the main volume of the kier inwardly through the package, through the spindle wall and into the central hollow space in the spindle.
  • a typical treatment cycle will include periodic switching between these two flow directions. This is a widely-accepted technique to minimise unevenness in the treatment.
  • the change in flow direction is achieved by a mechanical flow reversal device in the fluid circulation system together with a unidirectional pump.
  • the structure of flow reversal devices is such that the resistance to flow for the two flow directions is different, because the distance of travel and the nature of the flow is not the same.
  • the performance of the pump is also different for the two flow directions, giving different rates of flow.
  • different cycle times for the two flow directions are commonly used. The time difference is typically obtained through experience.
  • a first aspect of the present invention is directed to a method of controlling fluid flow rate during operation of a textile package fluid treatment machine, comprising: measuring the differential pressure across a unidirectional pump in a fluid circulation system connected to a kier of the machine and comprising a reversal device which is switched during operation of the machine to reverse the direction of fluid flow through at least one package in the kier; calculating an actual fluid flow rate through the fluid circulation system from the measured differential pressure using a performance characteristic of the pump; monitoring the actual flow rate over time to determine the accumulated flow between each switching of the reversal device; and using the accumulated flow information to automatically control switching of the reversal device such that total flow between each switching of the reversal device is substantially equal.
  • the method therefore corrects the flow rate for changes that typically exist between the two flow directions. Equal flow in each direction is important for achieving a good treatment result, but changes in flow rate may arise after each switching of the reversal device. By monitoring the accumulated flow after each switching operation, the switching can be carried out at the appropriate times to ensure that the total flow is the same.
  • the method allows the correct flow to be used without the need for any human estimation or experience, so that human error is removed from the treatment process, and better quality textiles can be produced.
  • the method may further comprise comparing the actual fluid flow rate with a desired fluid flow rate for the at least one package to determine any flow rate difference; and using the flow rate difference to automatically adjust operation of the pump such that the flow rate difference is reduced.
  • the method can be operated as a feedback arrangement to allow constant monitoring and adjustment of the flow rate throughout an entire treatment process so that any changes in flow rate arising from, for example, switching of the reversal device or fluctuations in pump performance can be compensated and corrected as they arise.
  • any reduction in the flow rate difference is advantageous, but preferably the method is used to substantially match the actual flow rate to the desired flow rate. Therefore, operation of the pump may be adjusted such that the flow rate difference is substantially eliminated. Several adjustments may be required to achieve this.
  • any suitable type of pump may be used.
  • the pump will be driven by a motor, in which case automatically adjusting operation of the pump may comprise automatically controlling operation of a motor that drives the pump.
  • the desired flow rate may be provided directly, if known. Alternatively, it may be determined for the particular treatment process to be performed from more readily available parameters. This simplifies things for the machine operator.
  • the method may further comprise calculating the desired flow rate from the size of the load in the kier and the performance index of the textile in the at least one package.
  • a second aspect of the present invention is directed to apparatus for controlling fluid flow rate during operation of a textile package fluid treatment machine, comprising: a differential pressure sensor connectable across a unidirectional pump in a fluid circulation system connected to a kier of the machine and comprising a reversal device switchable to reverse the direction of fluid flow through at least one package in the kier; a reversal device controller connectable to the reversal device and operable to control switching of the reversal device during operation of the machine; a flow rate calculator arranged to receive differential pressure data measured by the differential pressure sensor and operable to calculate an actual fluid flow rate through the fluid circulation system using a performance characteristic of the pump; and a levelness control unit arranged to receive the actual flow rate from the flow rate calculator and operable to monitor the actual flow rate over time to determine the accumulated flow between each switching of the reversal device, and to provide instructions to the reversal device controller to switch the reversal device such that total flow between each switching of the reversal device is substantially equal.
  • the apparatus may further comprise an input device for receiving operator input relating to a desired flow rate for the at least one package; a comparator operable to compare the actual flow rate and the desired flow rate to determine any flow rate difference; and a pump controller connectable to the pump, and arranged to receive flow rate difference data from the comparator and operable to adjust operation of the pump such that the flow rate difference is reduced.
  • Operation of the pump may be adjusted such that the flow rate difference is substantially eliminated.
  • the pump controller may be operable to adjust operation of the pump by controlling operation of a motor that drives the pump.
  • the input device may be configured to receive operator input of the size of the load in the kier and the performance index of the textile in the at least one package, with the apparatus further comprising a flow rate converter operable to calculate the desired flow rate from the operator input. This removes the need for the operator to know or calculate the desired flow rate, and allows the more simpler step of entry of more directly available data.
  • a third aspect of the present invention is directed to a textile package fluid treatment machine provided with apparatus according to any embodiment of the second aspect.
  • the machine may be a textile package dyeing machine, for example.
  • FIG. 1 shows a simplified schematic diagram of a conventional package dyeing machine with a fluid circulation system.
  • the machine 20 comprises a kier 22 for holding a plurality of textile packages during a fluid treatment process such as dyeing.
  • a fluid treatment process such as dyeing.
  • the package 26 is supported on a vertical hollow spindle 24 extending up from the base of the kier 22.
  • the base of the kier 22 also includes two fluid inlet/outlet ports.
  • One port 28 connects with the hollow interior of the spindle 24.
  • the other port 30 opens in the base of the kier 22 remote from the spindle to as to communicate with the main volume of the kier.
  • a fluid circulation system is connected to the ports 28, 30, and operates to circulate treatment fluid through the package 26.
  • the system comprises a pipe network 34 and a pump 36 in the pipe network operable to drive fluid around the pipe network 34 and into the kier 22.
  • the pump 36 is unidirectional and circulates fluid only in the direction indicated by the single-headed arrows.
  • a flow reversal device 32 is interposed between the pipe network 34 and the kier 22.
  • the reversal device 32 has an inlet 38 for receiving fluid from the pipe network 34 and an outlet 40 for returning fluid to the pipe network 34, plus connections to the two ports 28, 30 in the base of the kier.
  • a mechanical mechanism in the reversal device 32 can be switched between an inside-to-out flow position which connects the inlet 38 to the port 28 under the spindle 24 and connects the port 30 in the base of the kier 22 to the outlet 40, and an outside-to-in flow position which connects the inlet 38 to the port 30 in the base of the kier 22 and connects the port 28 under the spindle 24 to the outlet 40.
  • a range of flow reversal devices is known.
  • a typical treatment process comprises several alternating periods of flow in each direction, with the aim of providing equal total flow for each period.
  • the duration of the periods for the two flow directions must generally be unequal to compensate for differences in the resistance to flow for each flow direction, arising in part from the construction of the reversal device.
  • the timings are determined by user experience, and are hence prone to error.
  • Figure 2 shows a package dyeing machine similar to the conventional machine 20 of Figure 1 , comprising a kier 1 having a fluid circulation system comprising a pipe network 14, a reversal device 2 connected between the pipe network 14 and the kier 1, and a unidirectional pump 15.
  • the pump 15 is driven by a motor 4.
  • the machine is provided with an apparatus according to an embodiment of the invention for automatically controlling the fluid flow through the packages in the kier such that substantially equal amounts of flow can be provided in each flow direction during a single treatment process.
  • a pump has a performance characteristic that relates the flow rate it produces to the pressure difference (pressure head) across the pump.
  • Figure 3 shows an example of a pump performance characteristic, illustrated as a graph showing the relationship between the head and the flow rate.
  • the relationship is substantially linear with a shallow decline, such that a small change in the pressure difference (the decrease from point A to point B, for example) gives a large change to the flow rate (the increase from point r to point s, for example).
  • the present invention makes use of the relationship. The exact nature of the relationship is immaterial, so long as it is known or can be determined for the pump being used. Therefore, the invention is not limited to a pump with a performance characteristic as shown in Figure 3 .
  • the apparatus includes a differential pressure sensor 5. This is connected to the inlet 3 and the outlet 13 of the pump 15, so as to measure the pressure difference (differential pressure) across the pump 15 while the pump 15 is in operation to circulate fluid through packages in the kier 1.
  • the differential pressure will vary according to the rate at which the motor 4 is driving the pump 15, and the direction of flow as set by the reversal device 2.
  • the measured differential pressure is supplied from the sensor 5 to a flow rate calculator 6.
  • the flow rate calculator 6 is provided with information regarding the performance characteristic of the pump 15, and is operable to calculate the flow rate from the differential pressure, using the performance characteristic.
  • the calculator may be implemented by hardware or software. The calculation may be carried out using a look-up table that lists values of flow rate for the corresponding values of differential pressure, or using the equation that describes the curve of the performance characteristic, for example.
  • the apparatus further comprises a flow rate converter 7 connected to an input device 10 which allows an operator of the machine to enter a value for the flow rate at which it is desired that a treatment process should be carried out.
  • This value is supplied to the flow rate converter 7.
  • the input device 10 can allow user input of data from which the desired flow rate can be determined. This may be an input of the size or capacity 11 of the textile load that is to be contained in the kier 1, and an input of the performance index of the textile (a parameter describing the ease of treating that textile with the particular treatment fluid to be used).
  • the input device 10 may have a display screen, and a keypad, keyboard or other entry device via which the data can be entered. The display screen may show messages prompting the user to enter the required data. The data is entered before operation of the machine.
  • the flow rate converter 7 is then operable to calculate the desired flow rate from the data entered by the user. As with the flow rate calculator 6, this may be performed using equations or a look-up table, and by software or hardware.
  • the desired flow rate is obtained, it is supplied by the flow rate converter 7 to a comparator 16. Then, during operation of the machine, the comparator 16 also receives from the flow rate calculator 6 the calculated actual flow rate. The comparator 16 compares the two flow rates to determine any difference between them. A difference indicates that the pump is not circulating the treatment fluid at the appropriate flow rate for the process. To correct this, a motor controller 12 is arranged to receive flow rate difference data from the comparator 16, and, using the data, to generate and send control signals to the motor 4 to turn the motor up or down as appropriate to change the rate at which the pump 15 operates. Alternatively, the control signals may be generated by the comparator 16 and sent to the motor controller 12 which then operates to adjust the motor 4.
  • the aim of the adjustment to the motor 4 is to reduce the flow rate difference so that the actual flow rate substantially matches the desired flow rate. This may require several cycles of measurement and adjustment. Hence, the control may be carried out continuously during operation of the machine.
  • the magnitude of the flow rate difference determines by how much the motor is adjusted, and the sign of the flow rate difference determines whether the motor operation is increased or decreased. Further measurement of the differential pressure, calculation of the flow rate and comparison with the desired flow rate will determine if further adjustment to the motor is necessary, and so on.
  • the apparatus can provide a feedback loop for controlling the pump throughout operation of the machine.
  • the reversal device 2 can be operated such that the two flow directions are used for substantially equal time periods, to produce substantially equal total amounts of flow for each direction during each period and over the whole treatment process. This gives an even and uniform treatment of the textiles.
  • the machine might therefore be operated using periodic switching of the reversal device at pre-set intervals to match the flow times for each direction.
  • periodic switching of the reversal device at pre-set intervals to match the flow times for each direction.
  • a further embodiment proposes a dynamic control of the reversal device 2 to address this issue, and achieve equal flow in each flow direction.
  • the apparatus accordingly may further comprise a reversal device controller 9 connected to the reversal device 2 and operable to switch the reversal device 2 between its two positions.
  • a levelness control unit 8 is connected between the flow rate calculator 6 and the reversal device controller 9. The levelness control unit 8 continuously receives the real-time calculated actual flow rate from the flow rate calculator 6. It also generates control signals for transmission to the reversal device controller 9 to tell the reversal controller when to switch the reversal device. Therefore, the levelness control unit 8 knows which flow direction is being used.
  • the levelness control unit 8 operates by monitoring the actual flow rate over time for the two flow directions to determine the accumulated flow in each time period for each flow direction as the process proceeds. Based on this information, the levelness control unit 8 determines when the reversal device should be switched so as to achieve the same amount of flow for each time period of the reversal device, and hence a balance between the total inside-to-out flow and the total outside-to-in flow over the entire treatment process. Alternatively, the switching may be controlled only to achieve equal total flow in each direction over the whole process, and not for each individual period of flow between switching.
  • the levelness control unit 8 can be implemented by hardware or software, and may perform its function by use of an algorithm, for example.
  • embodiments of the invention provide automated dynamic control of the pump and the reversal device over the course of a treatment process carried out by the machine, to provide equal total flows for the two opposite fluid flow directions.
  • the treatment process with automated control can be initiated and completed without further operator input.
  • Control of the pump may be performed alone, or combined with control of the reversal device.
  • FIG. 2 shows the apparatus embodied as separate modules. Each module may be implemented using hardware, software or firmware as desired or as appropriate. The functions of more than one module may be combined within a single unit. For example, with the exception of suitable pressure transducers to provide the pressure measurements required to determine the differential pressure, the whole apparatus may be implemented as software running on a single processor that receives the pressure measurements from the pump and the desired flow rate data input by the operator, and outputs control signals to the motor and the reversal device.
