[0002]

2. Description of the Related Art Conventionally, for producing Japanese paper or foreign paper,
Basically, the following steps were taken. (1) The paper making liquid in which the paper making fibers and the like are melted is drawn into a container such as a bucket, and manually poured into a certain portion of the making tank from the bucket, and the paper making liquid is filled in the paper making tank. (2) A filter sheet material (92) is overlaid with a strained sheet material (91), and the strained frame material (43) is fitted into the filter sheet material (92). (3) Immerse the straining frame (43) prepared in step (2) into the paper straining solution filled in the straining tank (41) prepared in step (1), and leave the straining tank (41) stationary. Strain frame (43)
Straining work is performed by manually shaking the front and rear, left and right, and repeating the sinking and lifting of the straining frame. (4) After completion of the straining work, the strainer frame (43) is taken out from the strainer tank (41) to drain and dry, and the strained paper (P) is strained sheet material (91), filter sheet material (92). To remove.

[0003]

The above-described conventional papermaking of Japanese paper or foreign paper has the following problems. (1) In step (1), the papermaking liquid was drawn into a container such as a bucket, and was poured manually from the bucket to a certain part of the making tank (41). Therefore, the density of the papermaking fiber at the place where it was poured was Since the density of the papermaking fibers becomes large and the density of the papermaking fibers becomes small at a place far from the pouring place, the density of the papermaking fibers becomes non-uniform in the entire making tank (41). When the straining frame (43) prepared in the step (2) is immersed in such a papermaking liquid and the straining work is performed manually,
In the portion far from the poured portion, the papermaking fibers were insufficiently filled, and the thickness of the papermaking portion was uneven, and holes were left in a part of the papermaking portion. (2) In step (1), the papermaking liquid was drawn into a container such as a bucket, and was poured directly from the bucket into a certain part of the making tank (41) by hand. The paper (P) was turned up or torn. In addition, if there is a large step between the bucket and the strainer tank (41), the drop of the papermaking liquid will be large, so
The papermaking liquid is mixed too much and the fibers of the papermaking liquid are entangled. (3) In the step (3), since the shaking frame (43) is manually shaken back and forth, right and left, and the sinking and ascending operations are repeated, the scraping frame (43) is removed from a stationary paper making liquid. You will have to move the person manually. For this reason, the degree of uniform filling of the paper making liquid depends on the amount of movement of human hands, and the work efficiency is low, and the paper making fibers are insufficiently filled, resulting in uneven thickness of a part of the paper making paper. , There was a hole in part of the paper. (4) In the step (3), the straining tank (41) is kept stationary, and the straining frame (43) is manually shaken back and forth, right and left, and the sinking and ascending operation is repeated to perform the straining work. ) May collide with the strainer tank (41), or the excessively submerged strainer frame (43) may collide with the bottom of the strainer tank (41), giving unnecessary strain to the strainer frame and causing the worker to work. Work efficiency is low due to the use of central nerves.

[0014]

EFFECTS OF THE INVENTION According to the present invention described above, the strained sheet material (9
Since the papermaking liquid is poured by the papermaking liquid pouring means (3) having the pouring buffer plate (33) approaching 1),
It is possible to widely supply the paper making liquid to the making tank and the making sheet-shaped material (91). Therefore, the density of the paper making fibers can be made uniform in the whole making tank (41), and the paper making (P)
There is no unevenness in the thickness of some of the parts, and there are no holes in part.

Further, the paper pouring liquid pouring means (3) has a pouring buffer plate (33) approaching the filtering sheet material (91),
The paper-making liquid supplied to the pouring buffer plate (33) is poured into the sheet-shaped material (91) while receiving the paper-making liquid at a reduced flow rate, so that the strength of the paper-making liquid is minimized. It can be limited. Further, since the drop of the papermaking liquid flowing down is small, the papermaking liquid is not mixed too much, and the fibers of the papermaking liquid are not entangled more than necessary.

Further, in the present invention, when the straining sheet-like material (91) of the straining tank (41) is filled with the paper-slanting liquid, it is rocked back and forth,
Since the squeezing operation can be performed by oscillating in the left-right direction or tilting oscillating, the squeezing frame (43) and the paper making liquid integrally oscillate in the front-rear direction, the left-right direction, or the sloping sway. Therefore, the degree of the fiber filling of the straining sheet material (91) with the paper straining liquid becomes constant. Therefore, the thickness of the filter paper does not become uneven and some holes do not open. Also, since it has a suction means (5), excess fibers of the strained sheet material (91) can be forced to pass through, resulting in good work efficiency, insufficient filling of the straining fibers, and the thickness of the strained paper. There is no unevenness and there are no holes.

Further, since the squeezing tank (41) is capable of performing a squeezing operation by swinging in the front-back direction, swaying laterally or tilting while the sheet-shaped material (91) is filled with a sheet-making liquid.

As shown in FIG. 1, the construction of the paper making device according to the embodiment of the present invention stores the raw material and supplies the raw material to the paper making liquid preparation means (2) by the raw material supply means (1). A papermaking liquid preparation means (2) for mixing the raw materials to prepare a papermaking liquid, a papermaking liquid pouring means (3) for pouring the papermaking liquid into the papermaking sheet material (91), and a papermaking sheet material (9)
1) Straining means for giving a straining action to the papermaking liquid (4)
11, a sheet-forming material (91) and a suction means (5) for sucking the paper-making liquid, a liquid collecting means (8) for collecting an extra paper-making liquid (hereinafter referred to as “collection liquid”), and FIG. Strain paper (P)
Draining means (6) for removing water drops and the like adhering to the sheet, heating and drying means (71) and heating and pressure drying means (72) for drying the strained sheet (91) and the strained paper (P) shown in FIG. 12, and FIG. , 14 is made up of pressure heating and drying means (72).

As shown in FIG. 1, the raw material supply means (1) stores the raw materials for the papermaking liquid such as the papermaking fibers, the adhesive and the ionized water, and if necessary, these are stored in the papermaking liquid preparation means (2). )
Which is a means for supplying to papermaking fibers,
Textile tank for papermaking (11) that stores adhesive materials and other materials together
And an ion water tank (12) for storing ion water. Further, in order to adjust the recovery liquid, there is also a replenishment liquid tank (13) which stores a mixture of the raw material and ion water in advance as a replenishment liquid. The replenisher is for keeping the concentration of the mixed solution constant in addition to the mixed solution whose concentration has been lowered by returning the recovered solution. The supply to the stirring tank (21) described later is performed using the pump (14).

The papermaking liquid preparation means (2) has a finishing kneading tank (23) for kneading the raw materials to prepare a uniform papermaking liquid as shown in FIG. This finishing kneading tank (23) is shown in FIG.
A finishing kneading means (24) is installed as shown in FIG. Further, as shown in FIG. 1, a stirring tank (21) may be provided for mixing and stirring the raw materials from the raw material supply means (1) to prepare a mixed liquid. In this case, the mixed liquid mixed and stirred in the stirring tank (21) is supplied to the finishing kneading tank (23). This stirring tank
As shown in FIG. 2, stirring means (22) is installed in (21).

As shown in FIGS. 1 and 2, the stirring tank (21) is a stainless steel container for stirring and preparing a papermaking liquid,
The volume is about 600 liters. While having a stirring means (22) for stirring the upper straining fiber, the adhesive, the ionized water, and the replenisher supplied from the raw material supply means (1), the concentration, specific gravity and pH of the prepared mixed solution are measured, It has a densitometer, a pycnometer, and a pH meter for controlling certain properties. Here, the purpose is to stir the supplied raw material by the stirrer (22) so as to mix them uniformly, and not to loosen the entangled papermaking fibers. Further kneading for finishing is required to make it usable as a papermaking liquid. The recovered liquid is a stirring tank (21) as described later.
When the temperature is returned to 1, the concentration of the mixed liquid in the tank changes, so that a supplementary liquid is added to keep the concentration of the mixed liquid constant.

The stirring means (22) shown in FIG. 2 is for stirring the raw materials supplied as described above so as to mix them uniformly. Since the supplied raw materials have different concentrations, viscosities, etc. depending on the site, stirring is performed to prepare a mixed liquid having uniform viscosities, viscosities, etc. Further, as the raw materials, those having different specific gravities such as papermaking fibers are mixed, and heavy ones tend to settle, and therefore the stirring means (22) is preferably a means capable of sufficiently stirring near the bottom of the stirring tank (21), for example, It is preferable that the shaft is provided with a plurality of blades radially and the blade portion is rotated near the bottom of the stirring tank (21). If the finishing kneading tank (23) described later also serves as the stirring means (22), it is not necessary to provide the stirring tank (21), and the raw materials are directly supplied to the finishing kneading tank (23). .

The mixed liquid prepared in the stirring tank (21) is a raw material for Japanese paper or a raw material for western paper, a raw material for waste paper, wood pulp, chemical pulp, adhesive material, and ions, which are made of fibers supplied to the stirring tank (21). It is made of water, and is gently stirred by the stirring means (22) to make the fibers uniform, while maintaining a predetermined concentration, specific gravity and p
It is adjusted to H.

The finishing kneading tank (23) is a stainless-steel container for finishing kneading the mixed liquid to prepare a paper making liquid as shown in FIGS. 1 and 3, and has a capacity of about 600 liters. Finishing kneading means (24) for the mixed liquid supplied from the stirring tank (21)
The purpose is to gently knead with, and to loosen the paper-making fibers entangled in the liquid to make them uniform. In the raw materials and the mixed solution, the papermaking fibers are entangled and formed into a small lump, and the papermaking fibers are loosened there so that they can be uniformly filled. A densitometer for measuring the concentration, specific gravity and pH of the adjusted paper making liquid and controlling the predetermined properties,
It has a hydrometer and a pH meter.

The finishing kneading means (24) is a means for making a linear movement with respect to the paper making liquid, such as a means for reciprocating at a slow speed in the finishing kneading tank (23) using a rod-shaped body or a plate-shaped body. Is preferred. This is because the fibers for papermaking will be entangled with each other if a strong excess current is generated. A means for reciprocating a rod-like body or a plate-like body capable of reciprocating in the finishing kneading tank (23) at a slow speed by a reciprocating mechanism using a motor is preferable. The finishing kneading tank
(23) may combine the finishing kneading means (24) and the stirring means (22). Depending on the characteristics of the raw materials, it may be necessary to operate both means separately, or it may be possible to operate them simultaneously.

The paper making liquid pouring means (3) is for appropriately pouring the paper making liquid supplied from the finishing kneading tank (23) into the making tank (41) as shown in FIGS. 1 and 4. ,
From the main body container part (31) made of stainless steel that stores the paper making liquid and having a capacity of about 20 to 40 liters, the supply part (32) for supplying the paper making liquid, and the pouring buffer plate (33) Composed. Liquid pouring means for paper making
(3) is located below the finishing kneading tank (23) as shown in FIG. Then, in order to supply the paper making liquid from the finishing kneading tank (23), the valve provided at the lower part of the finishing kneading tank (23) is opened and closed. It is necessary to position the lower part of the finishing kneading tank (23) and supply the papermaking liquid in this way, if the papermaking liquid is poured into the papermaking liquid pouring means (3) by using a pump or the like, the papermaking liquid is unnecessarily mixed. This is because the fibers are entangled with each other before they are poured into the straining tank (41) to form a lump, which makes it impossible to fill the straining sheet-shaped material (91) with the fibers for filtering.

As shown in FIGS. 4 and 7, on the vertical surface of the supply part (32) formed in the main body container part (31), a long hole having a length of about 650 mm which is similar to the width of the later-described frame (43). An outflow port (34) is formed. A shutter means (35) for closing and opening the outlet (34) to stop the pouring of the papermaking liquid is provided in the supply unit (32) via the air cylinder, and is operated by driving the air cylinder. Outlet (34) to shutter means (35)
A seal member (36) made of an elastic material such as rubber or sponge is attached to the part in contact with, and the outlet (34) is slightly opened, and the paper making liquid is poured into the gap from the seal member (36) later. It is poured into the straining tank (41) through the buffer plate (33). The reason why the outflow port (34) has a long hole is that the papermaking liquid can be uniformly supplied to the papermaking sheet material (91), and the fibers and the like contained in the papermaking liquid are less likely to be clogged.

As shown in FIG. 7, an elastic sheet-like member (37) made of rubber or the like is attached to the inside of the supply part (32) so as to be applied to the outlet (34) from the inside. Elastic sheet member
(37) has an effect of flowing out the paper making liquid with a constant force regardless of the amount of the paper making liquid filled in the main body container part (31) when the paper making liquid is poured into the making tank (41). That is, when the main body container part (31) is filled with a large amount of the paper making liquid, the paper making liquid tends to flow out vigorously, but the liquid pressure causes the elastic sheet-like member (37) to cause the outlet (34 ) To block a part of the outflow port (34) to suppress the force of the papermaking liquid flowing out. As a result, it is possible to suppress the force of the paper-making liquid poured into the paper-making sheet material (91) via the flow-in buffer plate. On the other hand, when the main body container part (31) is filled with only a small amount of the paper making liquid, the elastic sheet member (37) has the outlet (34) because the liquid pressure of the paper making liquid is low.
The outflow port (34) can flow out a necessary amount of the papermaking liquid without being blocked by the deformation and sticking to the outflow port (34).
Further, since the structure is simple, the papermaking fibers and the like contained in the papermaking liquid are unlikely to be clogged.

As shown in FIG. 4, liquid pouring means for paper making
(3) has a pouring buffer plate (33) below the outlet (34) of the supply part (32). The pouring buffer plate (33) descends close to the straining sheet material (P) when pouring the polishing fluid into the polishing tank (41), and gently disperses the polishing fluid on the straining sheet material (P). It is something to pour without. Cast Buffer Plate (33)
Is a stainless plate having an L-shaped cross section, and the outlet (34)
Approximately 650m in length to correspond to the width of the frame (43)
m and the width is about 80 mm. The length of the buffer plate corresponds to the width of the outflow port (34) and the width of the frame (43), and the liquid for papermaking is made into the frame (43).
Avoid spilling outside. The stainless plate having an L-shaped cross section may be replaced with a stainless plate having an inverted T-shaped cross section. In this case, use a sheet-shaped material (91) with a large amount of papermaking liquid.
It is useful because it can be poured gently and evenly on top of. When the inside of the straining tank (41) is divided and the straining frame (43) is formed in a double shape, it has a straining operation means (4), and the pouring buffer plate (33) is placed in the middle of the straining frame (43). ) Is positioned and the papermaking liquid is poured thereinto, the papermaking liquid can be simultaneously poured into each of the making frames (43).

The pouring buffer plate (33) is attached to the supply unit (32) via an air cylinder, and can be moved up and down by driving the air cylinder. Therefore, the outlet (3
4) Once the papermaking solution that has flowed down from the
After it is received by (33) and the momentum of flow is softened, it is slowly and gently poured from the buffer plate (33) into the strained sheet material (91). When pouring the paper making liquid into the making tank (41), the distance between the pouring buffer plate (33) and the making sheet-like material (91) is preferably 10 to 50 mm. This is because the papermaking liquid cannot be poured on average unless the pouring strength of the papermaking liquid is softened. Especially when the paper (P) is thin paper, the pouring buffer plate (33) is brought close to the paper sheet (91) for pouring. In order to move the pouring buffer plate (33) up and down on the upper surface of the filtering tank (41), it is possible to use a driving device (33) such as a hydraulic cylinder, a cam or a crank in addition to the air cylinder.

The liquid pouring means (3) for the paper making is provided in the making tank (4
It is possible to move back and forth above 1), and it is placed on the rail (38) formed along the straining tank (41), and this rail (38)
Can be moved along. For the movement, a drive device (39) using a geared motor and a chain can be used, but a means using a stainless steel chain or a rubber timing belt is particularly preferable. Further, the speed at which the papermaking liquid is moved back and forth while pouring it into the making tank (41) is preferably about 50 mm / s.

As shown in FIG. 5 and FIG. 6, the paper pouring liquid pouring means (3) has the supply parts (32) formed at the front and rear of the main body container part (31) at two positions respectively. The outflow port (34) may be formed to have two outflow ports (34) and two inflow buffer plates (33) before and after the main body container part (31). In this case, it is possible to simultaneously pour the papermaking liquid into each of the front and rear divided frames (43) described later, which is preferable.

As shown in FIGS. 8, 9 and 10, the straining operation means (4) drives the straining tank (41), the straining operation means main body (42) supporting the straining tank (41) and the straining tank (41).

Two straining frames (43) are divided inside the straining tank (41) through the groove in the short direction in the entire circumference and in the center. Has been formed. If the size of the paper to be strained is large, a single frame (4
It is replaced by 3). Also, when the paper to be strained is oval, it is replaced with a more divided strainer frame (43). The inside of the filtering frame (43) is an opening, and the inner wall of each filtering frame (43) facing the opening is provided with a receiving member (43) that supports the crosspiece (91).
a) is formed. A receiving tank (44) is formed below the strainer frame (43) to receive the flown papermaking fluid. The suction port (44a) at the bottom is connected to a suction means (5) described later by a flexible pipe (52).

As shown in FIG. 9, a driving device (45) consisting of an air cylinder or a hydraulic cylinder or the like is provided vertically on each of the four sides of the bottom of the filtering tank (41), whereby the filtering operation means main body ( 42) supported. Both ends of the drive device (45) are rotatably attached to the straining tank (41) and the straining operation means main body (42). Further, as shown in FIG. 10, a strainer tank (41)
Is also supported by columns at the center of the lower surface,
The column can be moved up and down with respect to the main body (42) of the straining operation means,
The support column and the filtration tank (41) are connected using a universal joint mechanism (46). The universal joint mechanism (46) also has a role of preventing excessive shaking of the filtering tank (41) by limiting the swing angle.

The strainer tank (41) swings in the front-rear direction and the left-right direction in a state where the strainer sheet-like material (P) placed on the strainer sheet-like material (91) is filled with the paper-making liquid. It is possible to make a slanting motion by tilting rocking, and swinging in the front-back direction, left-right direction and tilting rocking is done by an air cylinder etc. (45) provided at the bottom of the grinding tank (41) and a universal joint mechanism (46).
