Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compact press-fit type fluid infiltration device that infiltrates a fluid into a sheet material in a short time.

[Conventional technology]

Conventional methods for infiltrating fluid into sheet-like materials.

Methods include (A) simply dipping the sheet into a fluid, and (B) nipping or vibrating the sheet with a mangle or the like while the sheet is immersed in the fluid. However, in the case of thick sheets, these methods require a relatively long time for the fluid to penetrate, which is a factor that inhibits production speed. Also.

Another problem was that a large soaking tank was required, resulting in the need to provide extra fluid in addition to that applied to the sheet.

In addition, for sheets that are difficult to penetrate with fluid, in order to allow fluid to penetrate in a short period of time, there are two methods: (C) creating a vacuum inside the sheet and then immersing it in the fluid; (D) soaking one side of the sheet in fluid. A method of suction from the opposite side while contacting the
) A method of pressurizing fluid into the seat has also been proposed. (
Methods using negative pressure as in C) and (D) cannot increase the pressure for infiltration very high, and also have problems in post-treatment when harmful gases are contained in the exhaust gas.

(E) does not have these problems, but C) ~ (E)
Therefore, it is necessary to effectively seal the pressure.

In particular, when the width of the running sheet changes or the position of the sheet edge changes due to meandering, etc., if effective sealing is not performed, pressure will drop and fluid will leak, making it impossible for sufficient fluid to penetrate.

Furthermore, as a sealing method for method (D) or method (E), the opening of the depressurized or pressurized pressure chamber that contacts the sheet is made narrower than the minimum width due to the positional fluctuation of the ends of both ends of the sheet, and the opening is always kept open. One method is to cover it with a sheet.

However, in this method, unpenetrated portions remain at both ends of the sheet, leading to a decrease in product quality and product yield, or to problems in later steps.

Other previously proposed sealing methods include:

The sheet is passed through a box-shaped pressure chamber, a sealing device consisting of a flexible rubber roll is installed at the entrance and exit of the pressure chamber, and the sheet is nipped with the roll.

There is also a method of dealing with positional fluctuations of the sheet edge ends.

However, this method also has disadvantages in that the sealing performance is insufficient when the sheet is particularly thick, and the apparatus is large and complex.

[Problem that the invention seeks to solve]

The present invention relates to a press-fit type fluid infiltration device.

When the position of the seat edge changes due to changes in the width of the traveling sheet or meandering, etc., fluid leakage from the pressure chamber opening near the edge and the resulting pressure drop are avoided, and at the same time, the fluid reaches the edge of the seat. The purpose of the present invention is to provide a device that can infiltrate.

[Means for solving problems]

The inventors of the present invention have made extensive studies to solve the above-mentioned drawbacks, and have found that the problems can be solved by adopting the following configuration, and have arrived at the present invention.

The present invention has the following configuration.

A pressure chamber with an opening on one side is provided inside the box-shaped body.

The opening is installed so as to be in contact with at least one surface of the sheet to force the fluid in the pressure chamber into the sheet, and at least one side of the pressure chamber is provided with a pressure chamber length that corresponds to changes in the position of the edge of the sheet. A press-fit type fluid, characterized in that a movable seal pro 7 for adjustment is provided, and a fluid permeation adjustment plate for pressurizing pressurized fluid into the seat ear is provided between the seal block and the seat ear. Infiltration device.

The present invention will be explained below using one embodiment of the present invention.

FIG. 1 is a schematic perspective view of a press-fit type fluid infiltration device according to the present invention.

2 is a partial sectional view taken along the line AA' in FIG. 1, and FIG. 3 is a partial sectional view taken along the line BB' shown in FIG.

In FIG. 1, numeral 5 is a sheet into which fluid is press-fitted, and it travels in the direction of the white arrow. Reference numeral 6 denotes a box-shaped body having an opening on one side toward the sheet surface, and a pressure chamber 1 is formed inside the box-shaped body 6 by the sheet contacting and covering the opening 21 . Pressurized fluid is supplied from the outside to the pressure chamber l through the inlet port 1.
It is sent from 1. Note that 12 is a fluid outlet;
14 is a peripheral surface of the box-shaped body 6 that contacts the sheet 5. Further, 7 is a sheet holding device, which can also close the opening 21 of the box-like body 6 relative to the sheet 5. pressure chamber l
The opening 21 may be provided with a perforated plate, a grid, a net, or a fabric ring, which allows pressurized fluid to pass through.

Note that the sheet holding device 7 may also be a box-like object that opens toward the sheet 5 surface, or a box-like object that has a porous object such as a perforated plate, a lattice-like object, a net-like object, or a cloth attached to the opening surface of the box-like object. can be used. Alternatively, it can be simply held down using a perforated plate or the like.

Furthermore, by using a box-like body as a sheet holding device, which has an opening facing the sheet 5 surface and into which pressurized fluid is supplied, like the box-like body 6, the sheet can be pressed as needed. It is also possible to press fluid in from both sides.

Depending on the conditions such as the tension of the sheet 5 and the pressure of the pressurized fluid,
Even without using the holding device 7, it may be possible to sufficiently seal the periphery of the opening 21 and maintain the pressure within the pressure chamber 1 at a required level.

The present invention maintains a seal near the edge of the peripheral edge of the opening 21 and maintains the pressure inside the pressure chamber 1 at a required level when the position of the edge of the traveling sheet changes. A method is adopted in which the comb 21 is narrower than the minimum width due to the positional fluctuation of the ends of both ears of the sheet, and the opening is always covered with the sheet.

This sealing method has solved the conventional problem of fluid not penetrating into the seat edges.

The present invention is solved by using the fluid permeation regulating plate 2 and seal block 3 shown in FIG.

The fluid permeation regulating plate 2 is made of a perforated plate or an assembly of many slits substantially parallel to the sheet running direction, and allows pressurized fluid to pass through the plate 2 in the thickness direction. Further, as the fluid permeation adjusting plate 2, a porous metal plate or resin plate through which fluid can pass may be used in some cases.

The seal block 3 comes into contact with the inner surface of the pressure chamber 1 of the fluid permeation adjustment plate 2 to stop fluid permeation from the contact portion, thereby regulating the fluid permeable region of the plate 2 .

Specifically, as shown in Fig. 2, the seal block 3 is movably slid in the lateral direction using a control rod 8 or the like according to changes in the position of the edge of the sheet, so that the fluid permeable area is almost up to the edge of the sheet. By regulating.

At the same time, fluid can penetrate into the seat edges while maintaining good sealing performance.

The movement of the seal block 3 when the sheet edge position changes is determined by detecting the sheet edge edge position, for example, by a detector installed inside the apparatus or on the front side of the apparatus in the running direction of the sheet.

Based on this, this can be done automatically by moving the control rod 8 as shown in FIG.

When using a seal block having a shape as shown in FIG. 4, for example, the seal block 15 is strongly pressed against the fluid permeation adjustment plate 2 by the pressurized fluid, so that the gap between the fluid permeation adjustment plate 2 and the seal block 15 is It is characterized by improved sealing performance. However, in this case, the friction between the fluid permeation adjusting plate 2 and the seal block 15 increases.

A large force may be required to slide the seal block 15.

If a seal block with a shape that partitions the side surface of the pressure chamber 1 as shown in Fig. 2 is used, the force with which the pressurized fluid presses the seal block 3 against the fluid permeation adjustment plate 2 will be reduced, so when sliding the seal block, it will be difficult to slide the seal block. The frictional force of is reduced. In this case, the seal block 3 can be compared by providing a pressure side chamber 4 on the back side of the seal block 3 with respect to the pressure chamber 1 as shown in Fig. 2 to counteract the force pushing the seal block 3 from the pressure chamber l side. The target can be slid with little force. Furthermore, as shown in Fig. 2, the pressure chamber 1 and the pressure side chamber 4 are
A pressure guiding path 9 is provided to communicate with the

The pressures in the pressure chamber 1 and the pressure side chamber 4 can be easily balanced.

Depending on the purpose, the amount of fluid permeating into the sheet edge may be smaller than that near the center of the sheet.For example, unavoidable damage may occur to the sheet edge due to the process of widening the sheet with a pin tenter. In cases where a product is manufactured by removing the ears after the fluid infiltration treatment process, the amount of fluid permeating into the removed ears may be the minimum amount that can prevent problems in the subsequent process. In such a case, it is effective to use a fluid permeation adjusting plate or a seal block that has a structure that reduces the amount of pressurized fluid that permeates toward the outside in the width direction of the sheet.

Specifically, the structure of the fluid permeation regulating plate illustrated in FIGS. 5 to 7 and the structure of the seal block illustrated in FIG. 8 or 9 can be used in combination as appropriate. Of these, in the seal block shown in FIG. 8, the second surface 17 is the pressure chamber l.
The two surfaces 16 are in contact with the fluid permeation regulating plate to regulate the fluid permeable region so that it becomes narrower toward the outside. In addition, in the seal block shown in FIG. 9, the first surface 20 partitions the side surface of the pressure chamber 1, and the ninth surface 18 comes into contact with the fluid permeation adjusting plate and delimits the boundary of the permeable region in the sheet width direction. 9 sides 1
The pressurized fluid in the pressure chamber 1 flows into the wedge-shaped gap formed between the pressure chamber 9 and the fluid permeation adjustment plate. The fluid that flows into the stk wedge-shaped gap and then passes through the fluid permeation adjustment plate has a pressure loss that gradually increases due to the shape of the gap, which gets narrower toward the outside, so the amount of permeation decreases toward the outside. .

By doing the above, even when the fluid permeable area on the fluid permeation adjustment plate protrudes to the outside of the sheet edge due to a change in the relative position between the seal block and the sheet edge, the protruding area can be removed. This is useful for stabilizing operations because it can alleviate the sudden ejection of fluid and the resulting pressure drop in the pressure chamber.

〔Effect of the invention〕

As explained above in detail, the press-fit type fluid infiltration device of the present invention has two features.

l) A fluid can be permeated into a sheet material in a short time.

2) The device can be made compact.

3) When changing the position of the edge of the sheet, it is possible to avoid fluid leakage near the edge and the resulting decrease in fluid osmotic pressure, while at the same time allowing fluid to penetrate to the edge of the sheet.

4) When using a seat holding part that presses the seat against the pressure chamber, it is necessary to insert something like a seal plate between the fluid permeation adjusting plate and the sheet holding part to prevent fluid leakage from the fluid permeation adjusting plate. Therefore, when pressing the sheet, it is easy to adjust the pressing pressure by continuously changing the gap between the pressing portion and the pressure chamber.

Furthermore, the apparatus of the present invention can be applied to sheet-like materials such as fibrous sheet-like materials such as cloth and paper, foam sheet-like materials, and permeable films.

Furthermore, the device of the present invention can be used to remove binder-eating solutions, dispersions,
It can be used for permeation of liquids such as cleaning liquids, extraction liquids, colored liquids, etc., or gases such as gases for heat treatment, cooling, and drying, and reactive gases.

Furthermore, the apparatus of the present invention not only permeates the fluid throughout the sheet thickness direction, but also permeates the fluid in the sheet thickness direction by selecting the pressure and viscosity of the fluid, the thickness and permeability of the sheet, and the permeation treatment time. It can also be used to allow fluid to penetrate partway through.

Among the devices of the present invention, the type in which a pair of pressure chambers are installed with the sheet sandwiched between them allows different fluids to penetrate from one side to a certain depth, and if necessary, it is possible to penetrate the sheet into the sheet. The two fluids can also be brought into contact with each other.
