Description

[Detailed description of the invention] Long objects such as textiles, tapes, and slide fastener chains are wound in multiple layers on the shaft of a porous hollow beam to form a cylindrical object, and the processing liquid is passed through the layers of the object to be processed. Processing is carried out through pressurized flow. At this time, a fan-shaped section is provided inside the hollow beam shaft to supply the pressurized processing liquid, and the part other than the fan-shaped section is used as a suction liquid passage section, and the beam axis and the section are made relative to each other. For example, the technique of rotating and moving the
It is described in Japanese Patent No. 0-40188 and West German Patent No. 2061348, and is well known.

The present invention prevents deformation and sagging of the object layer by arranging a plurality of paths for supplying the pressurized processing liquid and discharging the suction processing liquid symmetrically with respect to the beam axis in the above-mentioned known beam liquid processing apparatus. Moreover, the present invention provides an improved apparatus that can perform uniform and rapid liquid processing.

In other words, in the conventionally known beam liquid processing apparatus as described above, the pressurized processing liquid supplied from the inside of the hollow beam shaft flows through the subdivision range of the wound layer of the object to be treated, and due to the flow resistance, the wound layer is As a result of being extruded in one direction and moving in the direction of rotation while creating a large amount of slack when combined with liquid absorption from other parts, the winding layer tends to loosen and sag, especially on narrow tapes and zipper chains. In the case of spirally wound layers such as the above, there was a defect that caused deformation of the tape itself.

In view of this, the present invention was developed as a result of research into means to reduce the sagging of the wound layer as much as possible and to enable faster and more uniform liquid treatment. In addition to multiple positions, for the entire circumference of the winding layer,
The present invention was completed based on the finding that it is extremely effective to arrange the flow position symmetrically with respect to the axis in order to balance the stress within the wound layer caused by the flow of the processing liquid.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

Curved arc-shaped partition plate 54. A packing 57 having an appropriate width is fixed to the outer end of the member 54 so as to be in sliding contact with the inner surface of the perforated drum 61 of the beam 6, and the outer surface of the pressure liquid supply chamber E is shaped by the perforated plate 58.

The beam 6 having the rolled layer S of the material to be processed is rotated on the outer peripheral surface of the front and rear flanges 62 of the beam 6 by rollers 33 provided on a pedestal 32 that can be moved by wheels 31 on the rails 13 at the bottom of the processing tank 1. The inner surface of the porous winding drum 61 is fitted in sliding contact with the outer surface of the straightening tube 5, and the rear end of the beam 6 is fitted into the end of the rotating tube 14 provided inside the tank rear wall 3.
The front end of the beam 6 is held by a pin 15 and is fitted and held on the outer peripheral surface of a holding plate 22 rotatably supported by a push rod 21 of the tank lid 2 .

The rotary cylinder 14 is fitted onto the processing liquid supply pipe 4, has a worm gear 16 fixedly installed at its rear end, and is rotationally driven by a worm 17 rotated by external power.

18 is an upper liquid supply pipe, which branches from the liquid supply pipe 12 and is connected to a valve 19.
The distribution chamber 20 communicates with the approximately central upper part of the processing tank 1 through the

A fastener 28 is a pipe for supplying and discharging dyeing liquid, washing water, and other processing liquids.

Under the above structure, the beam 6 having the rolled layer S of the material to be processed is sealed and installed in the processing tank 1, and the desired processing liquid is supplied from the pipe 28 to the level 30 shown in FIG. In this state, the liquid is treated as follows.

The processing liquid is pressurized by the pump P, passes through the liquid supply pipe 12 and the processing liquid supply pipe 4, and flows from the porous rectification pipe 51 inside the rectification tube 5 to the pressure liquid supply chamber E arranged at a 90° phase difference in the radial direction. is supplied to the winding layer S, passes through the winding layer S, and further from the outer surface of the winding layer S,
It passes through the winding layer S and is sucked into the suction chamber V inside the rectifier cylinder 5,
The treatment liquid is circulated through the front and rear suction pipes 11 and 12, through the heat exchanger H, and to the suction side of the pump P as shown by the large arrow.
6, it is rotated in the direction of the small arrow while being in contact with the rectifying cylinder 5 along with the rotation of the rotary cylinder 14.

Therefore, the liquid flow direction of the wound layer S on the beam is changed four times for each rotation of the beam 6, and rapid and uniform liquid treatment is performed, and each pressurized permeation flow and suction permeation flow are Since the beam 6 advances with the winding layer divided into four equal parts, the relaxation and compression distribution of the winding layer is dispersed, and excessive swelling and deformation are prevented.

At this time, if gas is sucked from the liquid suction chamber surface exposed on the upper surface of the processing liquid level 30, bubbles may be generated in the wound layer S, resulting in processing spots, so adjust the valve 19 to A certain amount of processing liquid is supplied to the upper distribution chamber 20 of the processing tank 1 through the upper liquid supply pipe 18, distributed and distributed over the upper surface of the beam 6, and the processing liquid is sucked and permeated toward the upper liquid absorption chamber (2). Supply more than the amount of liquid.

By doing so, the low bath ratio treatment can be carried out efficiently and stably.

When the amount of processing liquid is increased until the processing liquid level 30 in the processing tank 1 sufficiently immerses the wound layer S of the beam 6, the valve 19 is closed and the liquid supply from the upper liquid supply pipe 18 is stopped. However, in such a case, as the temperature of the processing liquid increases, the liquid level may rise and excessive internal pressure may occur, so the excess liquid is allowed to overflow from the piping 25 to maintain the safety of the processing. However, depending on the processing conditions, the valves of the piping 25 are adjusted to communicate with the respective pressure sources so that a reduced or pressurized atmosphere is formed above the processing tank 1.

In the above embodiment, four sets of pressure liquid supply chambers E and four sets of liquid suction chambers V each having a phase difference of 90° are provided in the rectifier cylinder 5.
The number of sets or more may be set, or three sets with a 120° phase difference as shown in Fig. 3, or two sets with a 180° phase difference as shown in Fig. 4, depending on the beam design, the amount of material to be processed in the wound layer S, and the liquid processing conditions. It is also possible to adapt it to the following.

Furthermore, in place of rotating the beam 6 in the embodiment described above, the same effect can be obtained by rotating the rectifying cylinder 5 and keeping the beam 6 in a stopped state.

As explained above, according to the beam liquid processing apparatus of the present invention, pressurization and suction permeation of the workpiece, which is formed into a beam winding layer, are performed at multiple locations on the winding layer while maintaining the respective balance. An excellent industrial effect can be obtained in that a quick and good liquid processing effect can be obtained without causing undesirable sagging or deformation of the wound layer of the object to be processed.
