Abstract
Description
- The present invention generally relates to a conveyor drive fabric dyeing machine that is used to dye rope-like fabric, and more particularly to a control method for achieving operation synchronization of fabric and a fabric guide and a conveyor.

FIG. 1 shows a structure of a conveyor drive fabric dyeing machine, which comprises amachine body 1 in which adyeing tube 12, afabric guide 4, and aconveyor 2 are arranged. Thefabric guide 4 is driven to rotate by a fabric guide motor (not shown). Theconveyor 2 is driven and operated by a conveyor motor (not shown). - The principle of operation is as follows. Fabric 3 moves around the
fabric guide 4 and passes through anozzle 5 to enter thedyeing tube 12 and then falls onto theconveyor 2 to complete a cycle of circulation. Dye liquid L is pressurized by apump 7 to flow through a heat exchanger 8 (for heating or cooling) to enter thenozzle 5 for generating a jetting or overflowing hydraulic power that drives the fabric 3 into thedyeing tube 12. The fabric 3 that exits thedyeing tube 12 is allowed to fall back to theconveyor 2 and theconveyor 2 conveys the fabric 3 forward to pass through anidler 41 and thefabric guide 4 to repeatedly proceed with the above-described circulation cycle. In such a circulation cycle, acontrol box 9 controls the operation and dye and chemical agents are supplied from aservice tank 11 and pressurized by thepump 7 to feed into a dye liquid circulation loop of the dyeing machine. During the circulation, the dye liquid Land the fabric 3 undergo a process of heating, temperature holding, and cooling achieved with the heat exchanger 8 to have the dye absorbed by the fabric thereby achieving a dyeing effect of scouring, coloring, color fixing, and water rinsing. - The
conveyor 2 and thefabric guide 4 are respectively driven by the conveyor motor (not shown) and the fabric guide motor (not shown) to operate, while the fabric is driven by thefabric guide 4 to move. During the process of circulation, the time period that the fabric needs for each cycle of circulation must be identical to the time period that the conveyor takes to move from a rear end to a front end. In other words, the two must be operated in a synchronous manner, otherwise fabric entangling or jamming may result. Practically, the length or weight of fabric for each dyeing batch would be different so that the adjustment for synchronization is generally time consuming and difficult and often times, poor machine operation or low operation efficiency result. - An object of the present invention is to overcome the problem of unsmooth conveyance of fabric resulting from operation speeds of fabric driven by fabric guide and a conveyor of a dyeing machine being hard to be in synchronization with each other during a circulation cycle.
- To overcome such a problem, a computer or a programmable logic controller (PLC) control unit is included to automatically operate for computation and supply of a signal, based on data of fabric length or fabric weight and data of fabric unit weight fed to the computer or control unit, to a speed controller (such as an inverter) of a fabric guide motor and a speed controller (such as an inverter) of a conveyor motor so as to make the fabric guide motor and the conveyor motor rotate together with speeds that are of a predetermined ratio with respect to each other so that the speeds of the fabric and the conveyor are synchronized with each other and the circulation of the fabric can be performed smoothly.
- An advantage of the present invention is that it is not necessary to fix the length of fabric to be dyed and, regardless the length and weight of the fabric, the computer or PLC control unit performs automatic computation and controls the fabric guide and the conveyor and the fabric to achieve operation synchronization so as to make the circulation and conveyance of the fabric smooth and the operation of the machine is automatized, simplified, capable of greatly increasing production performance.
- The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

Fabric 3 moves around thefabric guide 4 and passes through anozzle 5 to enter thedyeing tube 12 and then falls onto theconveyor 2 to be conveyed forward so as to complete a cycle of circulation. Dye liquid L is pressurized by apump 7 to flow through a heat exchanger 8 (for heating or cooling) to enter thenozzle 5 for generating a jetting or overflowing hydraulic power that drives the fabric 3 into thedyeing tube 12. The fabric 3 that exits thedyeing tube 12 is allowed to fall back to theconveyor 2 and theconveyor 2 conveys the fabric 3 forward to pass through anidler 41 and thefabric guide 4 to repeat the above-described circulation cycle. In such a circulation process, acontrol box 9 controls the operation. Thecontrol box 9 comprises a computer or a programmable logic controller (PLC)control unit 91 mounted therein. Dye and chemical agents are supplied from aservice tank 11 and pressurized by thepump 7 to feed into a dye liquid circulation loop of the dyeing machine. During the circulation, the dye liquid Land the fabric 3 undergo a process of heating, temperature holding, and cooling achieved with the heat exchanger 8 to have the dye absorbed by the fabric thereby achieving a dyeing effect of scouring, coloring, color fixing, and water rinsing. - As shown in
