Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus used for various liquid treatments such as washing, dyeing, desizing, scouring, and resin impregnation of fabrics.

BACKGROUND TECHNOLOGY In general, as a continuous liquid treatment method for fabrics, there is a method in which a plurality of guide rolls are arranged in a zigzag pattern in a treatment liquid tank and the fabric is guided and transferred in a zigzag pattern (hereinafter referred to as the guide roll method). There is a known method in which the treatment liquid is conveyed in a tank by a net conveyor (hereinafter referred to as a conveyor method).

Problems to be Solved by the Invention In the conventional guide roll system, the freedom of the fabric in the processing liquid tank is restricted, and the processing such as washing with the processing liquid tends to be insufficient, and tension acts on the fabric. In addition, there are other problems, such as the fabric's texture being impaired, and the storage capacity of the fabric in the treatment liquid tank being small.

On the other hand, in the conventional conveyor system, although tension is not applied to the fabric, the front and back sides of the fabric are held by a net conveyor, which restricts the freedom of the fabric in the treatment liquid tank, and the cleaning process with the treatment liquid is difficult. This not only results in insufficient processing, but also inhibits the free expansion and contraction of the fabric during heat treatment, and furthermore, there are problems such as the storage capacity of the fabric in the treatment liquid tank is small.

Means for Solving the Problems The present invention was proposed in view of the above-mentioned problems of the conventional system, and includes a processing liquid tank with an open top, a plurality of separators mounted at equal pitches in the transfer direction, and One end is supported on the upper part of the processing liquid tank, the other end is immersed in the inner bottom of the processing liquid tank, and the other end is supported so as to be able to swing around the one end, and is intermittently driven at each mounting pitch of the separator. An inner circumferential conveyor with a shape of
an endless outer circumferential conveyor forming a shaped transfer path and driven intermittently in synchronization with the inner circumferential conveyor; a fabric supply device installed at the entrance of the U-shaped transfer path; A fabric liquid processing device is configured with a fabric take-out device installed on the outlet side.

Effects The present invention has the above-mentioned configuration, so that the fabrics supplied by the fabric supplying device are stacked in a free state between the separators, and are moved from the entrance to the exit of the U-shaped transfer path by the movement of the inner circumferential conveyor. Transferred intermittently. The outer conveyor prevents the fabric from flowing outward from between the separators of the inner conveyor.
Furthermore, by intermittent driving in synchronization with the inner conveyor, disturbance of the fabric existing between the separators of the inner conveyor is prevented. The fabric held between the separators of the inner conveyor is widened at the lower end position, improving the circulation of the fabric treatment liquid, and the inner conveyor moves back and forth around the upper end. By being oscillated, a shaking action is imparted to the spread cloth, and liquid treatment is sufficiently performed.

Embodiment FIG. 1 is a longitudinal side view showing an embodiment of the present invention, in which A is a processing liquid tank, B is an inner circumferential conveyor, C is an outer circumferential conveyor, D is a supply device, E is a take-out device, F is a
is a fabric.

The processing liquid tank A has an open top and a partition plate 1 inside.
An overflow type liquid supply tank 2 is installed on the outlet side of the fabric F, and an overflow type drain tank 3 is installed on the inlet side of the fabric F. It constitutes a liquid supply system in which the liquid is supplied in a direction opposite to the transfer direction, that is, a countercurrent type liquid supply system.For example, in the case of a washing process, the more the fabric F moves toward the outlet side, the more it is brought into contact with clean water.

The inner circumferential conveyor B has a large number of slats 4 connected endlessly in the transfer direction, a plurality of separators 5 installed at equal pitches in the transfer direction, and a drive chain wheel 6 at one end supported on the top of the processing liquid tank A. The driven chain wheel 7 at the other end is immersed in the inner bottom of the processing liquid tank A, and the driven chain wheel 7 side is supported so as to be swingable back and forth around the driving chain wheel 6. The mounting pitch of the separator 5 is intermittently driven.

The inner circumferential conveyor B includes, for example, a chain link 8 and a bracket 9, as shown in FIGS. 2 and 3.
Two types of slats 4a and 4b are attached alternately through the chain link 8, and a roller 11 with a double flange or one flange is attached to the connecting pin 10 of each chain link 8, and this roller 11 is guided and runs on a guide rail 12. I try to let them do it.

One of the slats 4a has protrusions 4a', 4a' that stand up outward at both ends in the transport direction, and the tips of these protrusions 4a', 4a' are folded back to prevent damage to the fabric F. By the protrusions 4a', 4a',
Separately from the separator 5, the positional shift of the folded end of the fabric F is regulated. The height of this protrusion 4a' is set lower than that of the separator 5.

The other slat 4b has both ends in the transport direction bent inward, and the slats 4b on both sides adjacent thereto
A and 4a are polymerized to form as small a gap as possible to prevent the fabric F from getting caught.

Both of the slats 4a, 4b have widths slightly larger than the maximum width of the fabric F to be handled, and the separator 5 is attached to either slat at the minimum width of the fabric F.

Moreover, the guide rail 12 of the inner circumferential conveyor B is
It is pivoted coaxially with the drive chain wheel 6 and is able to swing integrally with the shaft bearing of the driven chain wheel 7, and is provided with swing by an appropriate swing imparting mechanism, such as a crank mechanism. Ru.

In order to facilitate the removal of the inner circumferential conveyor B and the fabric F at the exit side, a drive chain wheel 6 is installed as shown in FIG.
has a diameter smaller than that of the driven chain wheel 7, and
The center of the driving chain wheel 6 is offset from the center of the driven chain wheel 7 toward the inlet of the fabric F, and the guide rail 12 makes the fabric inlet and outlet sides of the treatment liquid tank A parallel, and the outlet end The upper part is inclined toward the entrance side to widen the outlet for taking out the fabric F.

Next, the outer circumferential conveyor C connects a large number of slats 13 endlessly in the transfer direction, and has at least one driving chain wheel 14 so as to circulate inside and outside of the processing liquid tank A.
and a plurality of driven chain wheels 15, which are constructed in an endless manner,
Fabric F is processed in processing liquid tank A corresponding to inner circumferential conveyor B.
It forms a U-shaped transfer path 16, and is driven intermittently in synchronization with the inner circumferential conveyor B.

The specific structure of the outer circumferential conveyor C is the same as that of the inner circumferential conveyor B shown in FIGS. 2 and 3, and detailed description thereof will be omitted. However, the guide rail is installed at least in the processing liquid tank A, and is configured to swing together with the guide rail 12 of the inner circumferential conveyor B, or is fixed.

The constituent materials of the inner conveyor B and the outer conveyor C described above are materials that have corrosion resistance and rust prevention against various processing liquids, such as stainless steel.

Various types of shake-off mechanisms can be adopted for the fabric supply device D, but in FIG.
The figure shows a system in which the fabrics F are stacked and fed onto the separator 5 of the inner conveyor B while swinging back and forth. According to this method, the fabric F is evenly moistened with the processing liquid before being fed to the processing liquid tank A. To carry out cloth loading in an orderly manner.

The processing liquid injectors 17 and 18 include a processing liquid tank A.
A part of the drained liquid drawn out from the drained liquid tank 3 by the pump 20 via the filter 19 is branched and supplied. Incidentally, the remainder of the waste liquid is treated with a suitable waste liquid treatment device and then discharged or reused.

The fabric take-out device E includes a pair of feed-out rollers 2
1 and 22, and is connected to the rear washing machine, dryer, etc.

In FIG. 1, 23 indicates an outer casing.

One embodiment of the present invention has the above configuration, and its operation will be explained next.

In FIG. 1, when the operation is started, the inner circumferential conveyor B and the outer circumferential conveyor C are driven intermittently in synchronization with the set cloth supply amount (length).

The amount of movement of the intermittent drive is made equal to the mounting pitch of the separator 5 of the inner conveyor B, and
The moving speed and stopping time can be appropriately selected and set depending on the type of fabric F to be handled, processing conditions, etc.

Then, during the stop time of both conveyors B and C, supply by the supply device D and removal by the take-out device E are performed.

A predetermined amount of processing liquid is continuously or intermittently supplied to the liquid supply tank 2 .

In the treatment liquid tank A, the fabric F is intermittently transferred from the inlet to the outlet through the U-shaped transfer path 16 formed by the inner and outer circumferential conveyors B and C while maintaining the interval regulated by the separator 5. In this case, as shown in FIG.
Since the flat slats 4b and 13b are arranged alternately, the bent ends of the fabric F stacked between the separators 5 and 5 are aligned with the protrusions 4a' and 1.
3a', the cloth is prevented from shifting, and moves freely within the processing liquid tank A.

In the lower turn portion of the inner circumferential conveyor B, the interval between the separators 5, 5 is widened, the mutual interval between the stacked fabrics F is widened into a fan shape, and the flow of the processing liquid is improved. Since the inner circumferential conveyor B is oscillated around the drive chain wheel 6, and the swing width is larger toward the lower part, a rubbing effect is imparted by the shaking action in the spread state, and dirt, etc. from the fabric F can be removed well.

Since the new treatment liquid is supplied from the outlet side of the fabric F and discharged from the inlet side, the flow of the treatment liquid is in the opposite direction to the transfer direction of the fabric F.
The movement and shaking action of the processing liquid and the counterflow action of the processing liquid are compatible with each other to provide sufficient contact circulation and a kneading effect of the processing liquid. Then, it is taken out from the take-out device E while gradually coming into contact with fresh and clean processing liquid.

The above is the configuration and operation of one embodiment of the apparatus of the present invention, but the present invention is not limited only to the above embodiment, and various modifications are possible. For example, the slats and separators of the inner and outer circumferential conveyors , a liquid-permeable structure such as a perforated plate may be used.

Effects of the Invention According to the present invention, since the fabrics are stacked and supplied in a free state into the treatment liquid tank, the storage capacity (length) can be increased by 10 to 30 times compared to the conventional method, and of course, the fabrics are in a free state. Good contact with the treatment liquid is achieved, and the fabric is treated in a relaxed state without any tension or binding force acting on it, resulting in a rich texture and improved quality. Further, since the cloth can be swung in the spread state to obtain shaking and kneading effects, the contact with the processing liquid can be improved. Furthermore, the overall structure is simple and space-saving, and it saves power, resources, and energy.
