Description

[Detailed description of the invention] (Industrial application field) This invention is a fabric dyeing machine in which a long piece of fabric is continuously immersed in a dye solution in a dye bath and squeezed by a squeezing reroller. The present invention relates to a dye liquid supply device for supplying dye liquid to a tank.

(Prior Art) As a dye solution supply device for a fabric dyeing machine, the device shown in FIG. 3 is known. Reference numeral 1 denotes a dyeing device, which includes a guide roller 2, a dye bath 3, a dipping roller 4, a squeezing roller 5, etc., in which the fabric F is immersed in the dye liquid S by the dipping roller 3, and the dyeing device is dyed by the squeezing roller 5. After being squeezed, it is sent to a dryer (not shown). A dye liquor tray 6 is provided above the dye liquor tank 3, and any dye liquor S is fed to the dye liquor tray 6 from three side liquid preparation tanks 7 through a tray liquor feed pipe 8.
The dye liquor S is further flowed down from the dye liquor tray 6 to the dye liquor tank 3 below via a liquor tank liquid feed pipe 9. In addition, liquid feed pipe 8 for each tray
are respectively provided with a liquid preparation tank side solenoid valve 8a, a pump 8b, and a tray side solenoid valve 8c, and these tray liquid feed pipes 8 are respectively connected to the tray side solenoid valve 8c.
A drain electromagnetic valve 10a is provided in each drain pipe 10 formed by branching on the upstream side of the drain pipe.

Then, by opening/closing the solenoid valves 8a, 8c, and 10a and driving/stopping the pump 8b, the dye liquid S in any liquid preparation tank 7 is supplied to the dye liquid tank 3 via the dye liquid tray 6. While dyeing fabric F, one of the remaining two liquid preparation tanks 7 is washed, and the next lot of dye liquid is prepared in the other liquid preparation tank 7, and the stains from the above washing are removed. Water is discharged into the drain groove via the drain electromagnetic valve 10a and the drain pipe 10. Therefore, cleaning of the tray-side solenoid valve 8c, the tray 6 for the dye liquor, and the liquid supply pipe 9 for the liquor tank is carried out using a guiding cloth (not shown) interposed between the fabric F of the preceding lot and the fabric F of the succeeding lot. While the machine is running at low speed, the remaining dye solution S in the solution preparation tank 7 is sent to the dye solution tank 3 via the dye solution tray 6, and the dye solution tank 3 is tilted to transfer the above dye. This was carried out by discharging the liquid, then supplying wash water to the liquid preparation tank 7, and sending this wash water to the dye bath 3 in the same manner as above.

(Problem to be solved by the invention) Conventionally, the tips of the three tray liquid feed pipes 8 were fixed so that they were positioned above the dye liquid tray 6, and when changing lots, the three Since the dye liquid was changed by opening and closing the tray-side solenoid valves 8c installed in each of the book tray liquid feed pipes 8, the tray-side solenoid valves 8c and 8c used for dyeing the previous lot were changed. The tray 6 for the dye solution must be cleaned while the guiding cloth is running, and since the structure inside the tray-side solenoid valve 8c is complicated, cleaning takes a long time, which results in a long switching time. , productivity was declining. Although the dye liquor tray 8 can be quickly cleaned by separately providing a water supply port for cleaning water in its vicinity, the tray-side solenoid valve 8c cannot be cleaned even by this water supply port.

(Means for solving the problem) Instead of providing the tray solenoid valve 8c and the draining solenoid valve 10a, a draining tray 11 is installed near the dyeing liquid tray 6, and the tray liquid feeding pipe 8 An end pipe 13 that can be moved between the tray 6 and the tray 11 for draining liquid is connected to the tray side end of the tray 6 and the tray 11 for draining liquid, and a drain pipe 12 is connected to the tray 11 for draining liquid.

(Function) When the end pipe 13 of any tray liquid feed pipe 8 is directed toward the dye liquid tray 6, the dye liquid or washing water in the liquid preparation tank 7 to which the tray liquid feed pipe 8 is connected is dyed. The dye liquor is supplied to the dye liquor tank 3 via the liquor tray 6. Furthermore, when the end pipe 13 is moved and directed toward the drain tray 11, the dye liquid or washing water is discharged into the drain groove via the drain tray 11 and the drain pipe 12. Ru. Therefore, when changing lots, as soon as the liquid preparation tank 7 for the preceding lot is empty, the end pipe 13 of the tray liquid delivery pipe 8 is immediately moved to the draining tray 11, and the washing liquid is transferred to the dyeing liquid tray 6. Water is supplied to the tray 6 for the dye liquor, and the liquid feed pipe 1 for the liquor tank.
2 and the dye liquor tank 3, and at the same time as this cleaning is completed, the end pipe 13 of the tray liquid feed pipe 8 for the subsequent lot is moved from above the drain tray 11 to above the dye liquor tray 6, and The dye solution for the lot can be supplied to dye the subsequent lot, and the solution preparation tank 7 for the preceding lot and the solution feed pipe 8 for the tray can be
can be washed after starting the staining of subsequent lots.

(Example) In FIG. 1, a drainage tray 11 having almost the same shape as the dye solution tray 6 is located close to the dye solution tray 6.
A drain pipe 12 is connected to the bottom of the drain tray 11. On the other hand, a tray liquid feed pipe 8 is installed above the boundary between the dye liquid tray 6 and the drainage liquid tray 11.
An end pipe 13 made of a flexible tube is connected downward to this end, and its lower end is connected to the tip of a piston rod 21 of an air cylinder 14 provided almost horizontally. The lower end of 13 is the piston rod 21
It is formed so that it can be moved between the dye liquid tray 6 and the drain liquid tray 11 by moving forward and backward. However, as shown in FIG. 2, a tube guide 18 is connected to the piston rod 15 in a vertically swingable manner via a metal end 16 and a connecting pin 17. The end pipe 13 is loosely inserted to facilitate bending during movement.

In the above embodiment, the end pipe 13 connected to the tray liquid feed pipe 8 is not limited to a flexible tube, but for example, an inverted L-shaped pipe is used, and its horizontal portion is connected to the tray liquid feed pipe 8. It may be rotatably or slidably connected to the end. Further, instead of the air cylinder 14, a link mechanism operated by an electromagnet may be used. In addition, although the case where there are three liquid preparation tanks 7 is shown, it is sufficient if there are two or more.

(Effects of the invention) The tray-side solenoid valve that was conventionally installed at the tray-side end of the tray liquid delivery pipe is omitted, eliminating the need for troublesome cleaning. It is only necessary to stop dyeing while cleaning the liquid tank and the dye tank that follow it. The installed tank-side solenoid valve and pump can be cleaned after dyeing of the subsequent lot has started, so the downtime for cleaning when changing lots is shortened and productivity is improved.
