Description

[Detailed description of the invention] (Industrial application field) This invention is used in liquid processing pads for applying processing liquids such as dyeing liquids and resin processing liquids to long fabrics, and is suitable for processing when changing lots. This invention relates to a device equipped with a mechanism for lifting and lowering a processing liquid tank for cleaning the liquid tank.

(Prior art) As a pad for liquid analysis of fabric, JP-A-59-199858
As stated in the publication (see Figure 6),
A dipping guide roller 2 for immersing the fabric F in the treatment liquid W in the treatment liquid tank 1 is suspended from a frame (not shown) outside the treatment liquid tank 1 and is provided at an unchanging height. Tank 1 can be moved vertically and horizontally 1
It is fixed to the tips of a pair of levers (not shown) and is movable up and down, and the immersion guide roller 2 is immersed in the processing liquid W in the tank at the upper position A of the processing liquid tank 1, and the middle stage slightly below it. It is known that the immersion guide roller 2 escapes from the processing liquid tank 1 at position B, and the processing liquid tank 1 is tilted at a steep angle at the non-step position C, so that the processing liquid W in the tank is discharged. There is. In addition, 3
is the entrance guide roller, 4 is the expander roller,
5 is a squeeze roller, and 6 is a side frame.

(Problem to be solved by the invention) The conventional processing liquid tank 1 is fixed to the tip of a lever that swings up and down, and the lever is placed at the almost horizontal upper position A.
Since the immersion guide roller 2 moves up and down in an arcuate trajectory between the immersion guide roller 2 and the almost vertical non-step position C, the immersion guide roller 2 is moved up and down from the middle position B, where the immersion guide roller 2 escapes from the treatment liquid W in the tank.
However, the treatment liquid tank 1 was slightly tilted. Therefore, the lower half of the processing liquid tank 1 in which the processing liquid W is stored is formed in the shape of a gutter with a V-shaped cross section, that is, in a shape in which the distance between the front plate 1a and the rear plate 1b becomes wider at the top.
When the processing liquid tank 1 moves up and down between the upper position A and the middle position B, the immersion guide roller 2 is prevented from coming into contact with the front plate 1a or the rear plate 1b.
Therefore, when changing lots, a problem arises in that a large amount of the processing liquid W of the preceding lot remains in the processing liquid tank 1.

In addition, when the lower half of the processing liquid tank is formed into a U-shaped cross section, and the front and rear plates are arranged in parallel at a distance slightly larger than the diameter of the immersion guide roller 2,
Although the processing liquid W is saved, since the processing liquid tank 1 needs to be raised and lowered vertically, and the processing liquid tank 1 is supported horizontally even in the lower position C, it takes a long time to drain the processing liquid and the cleaning liquid. .

This invention allows the ascending and descending locus of the processing liquid tank to be set arbitrarily, and also allows the processing liquid tank to be tilted at a steep angle at the lower stage position.

(Means for solving the problem) A processing liquid tank is installed between the tips of a pair of left and right lifting levers that can be vertically swung so as to be slidable back and forth and swingable back and forth, and installed on the side of the processing liquid tank. A pair of left and right guide rails are provided which are curved in a curved direction, and the processing liquid tank is slidably fitted to the guide rails via sliding bodies fixed to the left and right sides of the guide rails.

(Function) When the left and right pair of lift levers are swung up and down,
The left and right sliding bodies of the processing liquid tank slide back and forth against the tip of this lifting lever, and swing back and forth, causing the processing liquid tank to move up and down along the guide rail while changing its inclination angle with respect to the vertical line. . That is, in the part where the guide rail is vertical, the processing liquid tank is held horizontally, and in the part where the guide rail is horizontal, the processing liquid tank is tilted at a steep angle, and the processing liquid in the tank is discharged.

(Example) In FIG. 2, the processing liquid tank 11 consists of a lower half part 11a with a U-shaped cross section and a flange-like upper half part 11b that spreads back and forth upwards, and the interval between the front and rear of the lower half part 11a is The diameter of the guide roller 2 is slightly larger than that of the guide roller 2. As shown in FIG. 3, the immersion guide roller 2 is rotatably supported at the lower end of an inverted L-shaped arm 2a fixed to the frame 6, and its height remains unchanged.

A support fitting 12 and a reinforcing plate 12a are fixed to the center of the side plate 11c (see FIGS. 2 and 4) of the processing liquid tank 11, and an upper stud 13 and a lower stud 14 are protruded along the vertical center line. An inner roller 13a and an outer roller 13b are rotatably mounted on the upper stud 13, and an inner roller 14a and an outer roller 14b are mounted on the lower stud 14, respectively.

In Fig. 1, the left and right side frames 6, 6
A lever shaft 15 in the width direction is rotatably supported via a bracket 16 on the fabric F supply side between the two, and a pair of left and right lifting levers 1 are fixed to this lever shaft 15.
7 is inserted between the upper and lower inner rollers 13a and 14a of the processing liquid tank 11. (See Figure 4). On the other hand, the outer rollers 13b and 14b are slidably fitted into grooves of a guide rail 18 having a U-shaped cross section and fixed to the inner surface of the side frame 6, thereby forming a sliding body for the guide rail 18.
This guide rail 18 is formed into a curved shape with an upper end facing in a substantially vertical direction, a lower part curved toward the supply side of the fabric F, and an end facing slightly upward. Roller (sliding body)
When 13b and 14b slide, the processing liquid tank 11 is supported horizontally at the upper end, and the processing liquid tank 11 is almost vertically tilted at the lower end.

Both ends of the lever shaft 15 are connected to the side frame 6
A drive lever 19 (see Fig. 2) is fixed to the protruding end of the piston rod 21a of the sub-fluid cylinder 21 constituting the elevating device 20. be done. The above-mentioned elevating device 20 is connected to the above-mentioned sub-fluid cylinder 21 and the main fluid cylinder 22 having a larger stroke in series on a common axis and in opposite directions to each other, and extends downward from the above-mentioned main fluid cylinder 22. The tip of the protruding piston rod 22a is connected to the side frame 6 by a bracket (not shown), and when both the piston rod 22a of the main fluid cylinder 22 and the piston rod 21a of the auxiliary fluid cylinder 21 protrude, processing is performed. Upper position A where the liquid tank 11 is horizontal
When the piston rod 22a of the main fluid cylinder 22 protrudes and the piston rod 21a of the auxiliary fluid cylinder 21 is retracted, the processing liquid tank 1
The processing liquid tank 11 is fixed at a middle position B where the immersion guide roller 2 escapes from the immersion guide roller 2, and the processing liquid W in the processing liquid tank 11 is discharged when both piston rods 21a and 22a are retracted. The processing liquid tank 11 is fixed at a non-step position C which is inclined at a steep angle. In addition, in Figure 2,
23 is a processing liquid supply pipe, 24 and 25 are washing liquid shower pipes, and 26 and 27 are splash prevention covers.

In the above structure, the treatment liquid tank 11 is fixed at the upper position A, and the treatment liquid W is immersed in the fabric F by controlling the liquid level to be constant, and is squeezed by the squeezing roller 5 and sent to the drying process. When changing lots, the processing liquid tank 11 is lowered to the non-stage position C to discharge the processing liquid W of the preceding lot, and then the processing liquid tank 11 is returned to the upper stage position A.
The cleaning liquid is sprayed from the cleaning liquid shower pipes 24 and 25 to clean the squeezing roller 5 and other parts, and the cleaning liquid is received in the processing liquid tank 11, and the processing liquid tank 11 is moved to the upper position A.
The processing liquid tank 11 is cleaned by reciprocating between the intermediate position B and the intermediate position B, and then the processing liquid tank 11 is lowered to the non-stage position C to discharge the dirt cleaning liquid. A guiding cloth is interposed between the fabric of the preceding lot and the fabric F of the succeeding lot, and after the processing liquid of the preceding lot is discharged, the processing liquid tank 11 is returned to the middle position B, and then, while spraying the cleaning liquid, The guide cloth may be transferred and the rollers may be wiped with the guide cloth.

Therefore, in this embodiment, the roller-shaped sliding body 13b of the processing liquid tank 11 is placed in the groove of the guide rail 18.
14b are fitted and rolled, so that sliding on the guide rail 18 is performed smoothly. Further, since the tip of the lifting lever 17 is inserted between the upper and lower inner rollers 13a and 14a, the processing liquid tank 11 can smoothly slide with respect to the lifting lever 17. In addition, at the tip of the lift lever 17,
As shown in FIG. 5, a substantially radial long hole 17a is formed, and the upper and lower inner rollers 13 are inserted into this long hole 17a.
Either one of a and 14a may be fitted. Further, in the above embodiment, the guide rail 18 is formed in the shape of a groove, but it may be formed in the shape of a single curved line and sandwiched between the front and rear sliding bodies fixed to the processing liquid tank 11.

(Effect of the invention) The ascending and descending locus of the processing liquid tank can be arbitrarily set depending on the shape of the guide rail. For example, as shown in the example, by orienting the upper end of the guide rail almost vertically and the lower end almost horizontally,
Between the upper stage position and the middle stage position, the processing liquid tank can be raised and lowered vertically without tilting, and after being lowered near the lower end, it can be tilted sideways. Therefore, even if the processing liquid tank is formed into a small size with a U-shaped cross section, it is possible to avoid contact with the immersion guide roller when descending from the upper stage position.
