Abstract

In a dyeing machine, cloth guided by roller 5, dye jet 1 and passage 3 is carried by conveyor 62 through receiving chamber 2. Cloth is guided by fixed end guide 64, and by end guide 63 which pivots, when the cloth wrinkles, to actuate sensor 65 to stop the conveyor until roller 5 moves the cloth and straightens the wrinkles. Alternatively (Fig. 2, not shown), the guides are replaced by circulating, inclined conveyors. In an arched receiving chamber (Fig. 3, not shown), conveyor 62 runs along the curved bottom surface of the chamber.

DYEING MACHINE WITH CLOTH CONVEYER MEANS BACKGROUND OF THE INVENTION

The present invention relates to dyeing machines, and more particularly to such a dyeing machine which comprises a conveyer and a set of cloth guide rollers for delivering cloth through a cloth passage for dying..

Acdording to regular dyeing machines, the inserted piece of cloth is carried through a receiving chamber by the flowing force of provided dyeing solution and the gravity of the inserted piece of cloth. Because the piece of cloth to be dyed is carried forwards by dyeing solution, much dyeing solution must be provided. When much dyeing solution is provided, much waste water will be produced. When the inserted piece of cloth is circulated through the receiving chamber, it may easily be forced to anale. When dyeing different cloth, the flow rate must be properly controlled so that inserted cloth can be smoothly delivered through the receiving chamber. However, it is not easy to control the flow rate subject to the nature of the cloth to be dyed. When a thick piece of cloth is put in the dyeina machine, it cannot be moved forwards smoothly. Further, when the inserted piece of cloth is moved in the receiving chamber, it may be forced to rub against the inside wall of the receiving chamber, causing the fabric 1 structure to be damaged. SUMMARY OE THE INVENTION

The present invention has been accomplished to provide a dyeing machine which eliminates the aforesaid problems. Accordina to one aspect of the present invention, the dyeing machine comprises a receiving chamber, a cloth passage disposed in combination with the receiving chamber through which a piece of cloth is inserted and dyed, a jet nozzle suspended above a front end of the cloth passage and controlled to spray a dyeing solution for coloring the inserted piece of cloth, and a cloth guide roller suspended above the. et nozzle and turned to guide the inserted J li piece of cloth from the front end of the cloth passage through the jet nozzle toward a rear end of the cloth passage, wherein a rnotor- dfiven cloth conveyer is mounted within the receiving chamber at a bottom side and controlled to deliver the inserted piece of cloth through the cloth passage; a detector is mounted inside the receiving chamber to detect the movement of the inserted piece of cloth, and to cut off power supply from the motor-driven cloth conveyer when the inserted piece of cloth is jammed.

According to a,-.other aspect of the present invention, two cloth guide means are mounted inside the receiving chamber adjacent to two opposite ends of the motor-driven cloth conveyer for guiding 2 the inserted piece of cloth from the front end of the cloth passage to the cloth conveyer and from the cloth conveyer to the rear end of the cloth passage. According to still another aspect of the present invention, the cloth guide means can be cloth guide plates, or auxiliary belt conveyers.

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 is a side plain view of a dyeing machine according to the present invention; Fig. 2 is a side plain view of an alternate form of the present invention; and Fig. 3 is a front view in section of another alternate form of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to Figure 1, a dyeing machine in accordance with the present invention is generally comprises a cylindrical receiving chamber 2, a cloth passage 3, a jet nozzle 1 suspended on the inside at the top, and a cloth guide roller 5 disposed in front of the jet nozzle 13. When a piece of cloth 7 is inserted into the dyeing machine, it is circulated through the cloth passage 3 and dyed.

Referring to Figure 1 again, a cloth conveyer 6 is mounted inside the receiving chamber 2 at the bottom, and controlled to deliver the inserted piece of cloth 7. The cloth conveyer 6 3 comprises a set of rollers 61, a conveying belt 62 mounted around the rollers 61, and a motor drive (not shown) driven to turn the rollers 61. When the rollers 61 are rotated by the motor drive, the conveying belt 62 is turned to deliver the piece of cloth 7. A fixed front cloth guide plate 63 and a movable rear cloth guide plate 64 are installed in the receiving chamber 2 near two opposite ends of the cloth conveyer 6. The front cloth guide plate 63 is fixedly fastened to the inside wall of the dyeing machine. The rear cloth guide plate 64 is pivoted to the inside wall of the dyeing machine.. The front cloth guide plate 63 is adapted to guide the inserted piece of cloth 7 from the cloth passage 3 to the conveying belt 62. The rear cloth guide plate 64 is adapted to guide the inserted piece of cloth 7 away from the conveying belt 62 to the cloth passage 3. Further,,a detector 65 is mounted inside the dyeing machine adjacent the fixed front cloth guide plate 63. If the inserted piece of cloth 7 is wrinkled and gathered together at the rear cloth guide plate 64 and unable to be delivered smoothly forwards, the rear cloth guide plate 64 will be forced by the inserted piece of cloth 7 to tilt to a certain angle. When the rear cloth guide plate 64 tilts over a predetermined angle, the detector 65 is immediately triggered to cut off power supply from the motor drive of the cloth conveyer 6, permitting the wrinkled cloth section 4 of the inserted piece of cloth 7 to be delivered forwards by the cloth guide roller 5. As soon as the inserted piece of cloth 7 is pulled straight, the rear cloth guide plate 64 immediately returns to its former position, and the detector 65 is triggered again to turn on the motor drive of the cloth conveyer 6, for permitting the inserted piece of the cloth 7 to be smoothly delivered through the cloth passage 3.

Figure 2 shows an alternate form of the present invention, in which two cloth guide assemblies 62 are mounted inside the receivina chamber 2 and obliquely aimed at two opposite ends of the cloth conveyer 6, and adapted to guide the inserted piece of cloth 7 from the front end of the cloth passage 3 to the conveying belt 62 and from the conveying belt 62 to the rear end of the cloth passage 3 continuously.. Each cloth guide assembly 62 is comprised of two rollers 66, and a conveying belt 62 mounted around the rollers 66.

Figure 3 shows another alternate Torm of the present invention, in which the receiving chamber, referenced by 4, has an arched configuration, and the rollers 61 of the cloth conveyer 6 are arranged along the smoothly curved bottom wall of the receiving chamber 4.

It is to be understood that the drawings are designed for purposes of illustration only, and are not intended as a definition of the limits and scope of the invention disclosed.
