DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper forming apparatus for forming a paper layer and a paper by bearding defibrated fibers obtained by pulverizing pulp, and more particularly to relying on moisture (including liquids other than water). The present invention relates to a dry paper forming apparatus for performing defibration and bearding without any problem.

[0002]

2. Description of the Related Art To manufacture paper from wood, first, wood is processed to form a pulp mass (also referred to simply as pulp), which is a mass of fibers, and the fibers of the pulp are defibrated to form paper. I will do it. In the case of a conventional paper forming apparatus, as shown in FIG. 6, pulp 1 is charged into a receiving tank 102 containing water, and pulp 1 and water are stirred in the receiving tank 102 to disintegrate pulp fibers. I do. Thereafter, in a state where the fibers are mixed with a large amount of water, the fibers are fed from the raw material inflow pipe to the raw material box 104 through processing steps such as fiber bearding and dust removal. Note that the pulp 1 is put into the receiving tank 102 in a state of a pulp mass formed by stacking, for example, fiber-shaped sheets as shown in FIG. 7 to form one rectangular parallelepiped (for example, having a thickness of about 10 cm).

[0003] The fibers of the defibrated paper (defibrated fibers) are sent from a raw material outlet 105 of the raw material box 104 to a paper layer forming section 106 of a paper forming apparatus. At this time, the disintegrated fibers sent to the paper layer forming unit 106 are 1% of fibers and the remaining 99% are in water. Then, in the paper layer forming section 106, the raw material outlet 1
The defibrated fibers flowing out of the web 05 are placed on the fourdrinier 107 and dewatered to continuously form a paper layer. In the case of this apparatus, about 20% of the fiber is on the exit side of the paper layer forming section 106, and about 80% of the remaining fiber is in a water state.

[0004]

However, in the conventional paper forming apparatus, as described above, a large amount of water is used to disintegrate the fibers of the pulp.
Then, the remaining 99% is in a very watery state of water. Use of such a large amount of water is not preferable considering that water is a precious resource. Also,
The energy consumption for moving a large amount of water also increases.

Further, if an attempt is made to remove a large amount of water, the processing time of a paper forming line or paper formation tends to be long, and the use of a large amount of water is not preferable in this respect. Of course, in order to form a paper layer from the defibrated fibers, it is necessary to bond the bearded fibers to each other. It is desired that the papermaking quality can be ensured while reducing the water content at the time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is intended to form paper of a predetermined quality from pulp by using as little moisture (including liquids other than water) as possible. It is another object of the present invention to provide a dry paper forming apparatus.

Disintegration is performed by mechanical processing.

The rotary cylinder 12 is installed horizontally in FIG. 1, but as shown in FIG. 2, a lower support 15A fitted on the outer periphery of the front end and an upper support 15 fitted on the outer periphery of the rear end. It is preferable that the pulp outlet 12B at the front end is inclined and installed such that the pulp outlet 12B at the front end is located lower than the pulp inlet 12A at the rear end, by pivotally supporting the base 15B so as to be rotatable around the axis. When the rotary cylinder 12 is installed inclined as described above, the pulp 1 put into the rotary cylinder 12 through the transport conveyor 11 can be easily moved from the pulp inlet 12A to the pulp outlet 12B by its own weight.

The blower 13 has, for example, a fan (not shown) and sends air into the rotary cylinder 12 through a blow duct 13A to move the pulp 1 in the rotary cylinder 12 from the pulp inlet 12A to the pulp outlet 12B. Therefore, the pulp 1 put into the rotary cylinder 12 moves from the pulp inlet 12A to the pulp outlet 12B by the wind of the blower 13 and the inclination of the rotary cylinder 12 as described above. As described above, the pulp 1 charged into the rotary cylinder 12 is forcibly driven to the pulp outlet 12B by the wind of the blower 13, so that even if the rotary cylinder 12 is installed horizontally as shown in FIG. To work.

A rotary cylinder driving device 14 for rotating the rotary cylinder 12 around its axis includes a motor 14A, a speed reduction mechanism 14B, a first gear 14C, which are installed separately from the rotary cylinder 12; A second gear 14D is provided on the outer periphery and meshes with the first gear 14C. The rotation of the motor 14A is reduced by the reduction mechanism 14B and the rotational force is amplified and transmitted to the first gear 14C.
The rotary cylinder 12 is driven to rotate through 4D.

The vibration plate 17 has one end (top end) connected to and supported by the vibration plate fixing support device 17A, and the other end (rear end) connected to the vibration generation device 16. It is driven and vibrates. Also,
The micro-vibration plate 18 is driven by a micro-vibration generator 18A to vibrate finely. Such vibration of the vibration plate 17 and fine vibration of the fine vibration plate 18 are intended to apply vibration to the pulp 1 in the rotary cylinder 12 to promote the disintegration of the pulp 1.

In this case, the vibration plate 17 which operates with vibration having a relatively large amplitude and a relatively small frequency (low frequency) is used.
And the amplitude is relatively small and the frequency is relatively large (high frequency)
There are two types of diaphragms, a fine diaphragm 18 that operates by vibration, and four types of diaphragms, for example, strong, medium, weak, and fine, are installed. A large number of diaphragms having different vibration frequencies or different vibration frequencies may be provided. Thereby, various vibrations can be given to the pulp 1 and the disintegration of the pulp 1 can be promoted.

Further, a part or all of the diaphragm is configured to have a variable vibration characteristic (vibration intensity and frequency) to change the characteristic of the vibration applied according to the type of the pulp mass 1 or the like. Further, even when the same pulp mass 1 is vibrated while changing the vibration characteristics, various vibrations can be given to the pulp 1 and the disintegration of the pulp 1 can be promoted. In the case of such a diaphragm having variable vibration characteristics, only one or a plurality of types of diaphragms may be provided.

A large number of claws 19 projecting from the inner periphery of the rotary cylinder 12 hold the rotary cylinder 1 when the rotary cylinder 12 rotates.
A motion is given to the pulp 1 in 2 to promote the disintegration of the pulp 1. The claw 19 has various shapes such as a square, round, flat, or conical tip, and
The tip is bent, or the tip is formed linearly in a direction toward the axis of the rotary cylinder 12, or in a direction appropriately inclined with respect to the axis or the direction toward the axis. And the like are prepared in a variety of lengths and short lengths, and these can be replaced.

Thus, an optimum one is selected from these various claws 19 in accordance with the type (material and shape) of the pulp mass 1 to be defibrated and the characteristics of the paper to be formed. It has become. Of course, pulp lump 1
If the type of paper and the characteristics of the paper to be formed are specified, the nail 19 may not be replaceable and a nail having an optimal shape may be fixedly provided.

With such a configuration, in the fiber disintegration section 10, the pulp 1 charged into the rotary cylinder 12 moves from the pulp inlet 12A to the pulp outlet 12B due to the wind of the blower 13 and the inclination of the rotary cylinder 12. At this time, a large number of claws 19 on the inner circumference of the rotary cylinder 12 move in the rotary cylinder in accordance with the rotary cylinder 12 by the rotary cylinder drive device 14, and the vibration of the diaphragm 17 and the fine vibration of the fine diaphragm 18 cause Disintegrated fiber 2 given vibration
As a result, it is sent to the fiber beard 20 in the next step through the disintegrated fiber guide channel 21A.

The fiber beard 20 is, as shown in FIG.
A defibrated fiber inlet 21, a defibrated fiber guide flow path 21A, a beard portion main body 20A, and a feed pipe 27 are provided, and the defibrated fibers 2 are bearded while moving in this order. In particular, the beard portion main body 20A includes two surface grooved rolls 22 and 23 facing each other in a case 24, and the defibration fiber inlet 2 is provided.
1, so-called bearding is performed by passing the defibrated fibers 2 sent by wind through the defibrated fiber guide passage 21A between the rolls 22 and 23 having surface grooves, and performing mechanical processing without relying on water. Has become.

In addition, one of the defibrated fibers 2 generally has a length of 0.3 mm.
5 to 6.0 mm and a width of about 5 to 70 μm. In the beard, finer fibers are fluffed from the surface of each fiber, and in the subsequent paper layer forming step, each defibrated fiber 2 is fluffed. The fine fibers are entangled with each other and strongly bonded. Such bearding is performed by sandwiching the defibrated fiber 2 between the grooved outer peripheral surfaces 22B and 23B of the rolls 22 and 23.
The roll 23 can adjust the rotational speed and adjust the gap between the rolls 22 and 23.
The beard amount and the processing amount (processing speed) are adjusted by adjusting the rotation speed of the rollers 2 and 23 and the gap between the rolls 22 and 23.

The case 24 covers the rolls 22 and 23 so that the rolls 22 and 23 are not exposed to ensure safety, and shields the disintegrating fibers 2 flowing inside from the outside so as not to be scattered outside. And has a box-shaped structure. The shafts 22A, 2 of the rolls 22, 23
3A protrudes out of the case 24, and each shaft 2
One end of each of 2A and 23A is connected to a driving device 26, and is driven to rotate by the driving device 26.

Downstream of the rolls 22, 23 in the case 24, conduits 25, 25 are respectively introduced from the left and right, and the openings of these conduits 25, 25 are provided by feed pipes 27.
The air is supplied to the conduits 25, 25, and the bearded defibrating fibers (hereinafter referred to as bearded defibrating fibers) 2A pass through the feed pipe 27 by the air. It is sent out to the process.

As shown in FIG. 4, the paper layer forming section 30 includes a guide plate 3 provided at an outlet 27A at the downstream end of the feed pipe 27.
1, a moving blanket 3 disposed so as to form the lower surface of the paper layer forming line L, and a water supply mechanism 32 provided above the paper layer forming line L. The guide plate 31
A guide surface 31A is provided above the entrance of the paper layer forming line L and gradually approaches the moving blanket 3. Through this guide surface 31A, defibrated fibers bearded by the fiber beard portion 20 (beard defibrated fibers) are provided. 2) The 2A is guided so as to be stably placed on the moving blanket 3 in a uniform band shape.

The moving blanket 3 includes a plurality of rolls 33, 34,
A belt-like body made of a blanket-like material wound around 47, and a driving roll (for example, one of rolls 33, 34, and 47)
, And moves in the direction of the next process (that is, in the direction of the paper forming unit 40). The beard disintegration fiber 2A is formed on the moving blanket 3 while moving on the paper blanket.

The water supply mechanism 32 is provided with the moving blanket 3.
This is a shower in which diluted starch (relatively low-concentration water-soluble starch) 32A as water is sprayed onto the aggregate of beard disintegration fibers 2A placed in a belt shape on the top. The shower 32 is provided with a large number of injection ports 32C below the injection pipe 32B so as to uniformly supply the diluted starch to each beard disintegration fiber 2A by showering. 3
The diluted starch supplied in 2B is sprayed from the injection port 32C.

As described above, the diluted starch 32A is sprayed on the aggregate of the bearded defibrated fibers 2A. This is because water is required to form individual fibers into a sheet for forming a paper layer. This is because a sticky material such as starch is required in order to strengthen the bonding between individual fibers and prevent the fiber beard on the front and back of the formed paper from splashing. That is, when the wood fibers are formed into a sheet, the individual fibers are formed by hydrogen bonding, so that water is required for forming the sheet. The sticky material such as starch increases the mutual bonding force between the bearded fibers of the beard disintegration fiber 2A and the droplets of fine fibers which are the fiber beards on the front and back surfaces of the formed paper sheet. It works to prevent it.

As described above, the diluted starch to be sprayed is used for bonding individual fibers with water as described above,
The purpose is to strengthen the bonding of the individual fibers by the starch and to prevent the fine fibers which are the fiber beards on the front and back surfaces of the paper sheet from being formed, and the amount of the atomized spray is sufficiently small. In addition, a liquid other than water may be applied to form the fiber into a sheet shape, and another sticky substance may be used instead of starch.

As shown in FIGS. 4 and 5, the paper forming section 40 includes a heating roll 41 and a pressure roll 42 provided in pairs so as to face each other. The sheet (paper sheet) 2B on which the paper layer is formed passes on the moving blanket 3 and passes between the heating roll 41 and the pressure roll 42. At this time, the paper sheet 2B comes into contact with the heating roll 41. As a result, the heating roll 41 is pressed against the heating roll 41 by the pressure roll 42.

The heating roll 41 is provided with a heater or the like inside, or a heating medium is introduced therein. The heating roll 41 heats the surface of the heating roll 41 to a predetermined temperature, and the surface of the heating roll 41 is heated. The paper sheet moving while being pressed against is heated to remove moisture contained therein. In particular, heating roll 4
The roll 47 that guides the moving blanket 3 downstream of 1 moves the paper sheet 2B together with the moving blanket 3 toward the heating roll 41 in the moving direction (ie, by a large central angle of the heating roll 41).
The heating roll 41 and the pressure roll 42 are disposed so as to approach (or contact) the heating roll 41 at a position separated from the contact portion between the heating roll 41 and the pressure roll 42 so as to be in contact with each other.

The pressing roll 42 is urged by a pressing member 43 toward the heating roll 41 with an appropriate pressing force. In this embodiment, one end of the pressing member 43 is pivotally supported by the pin 44, and the other end of the pressing member 43 is
Actuator (here, hydraulic cylinder) 4 through 5
6 is connected, and the heating roll 4 of the pressing roll 42 is
The pressure contact force to one side can be adjusted. In addition,
The up and down arrangement of the heating roll 41 and the pressure roll 42 may be reversed.

Since the dry paper forming apparatus according to one embodiment of the present invention is configured as described above, the paper sheet 2B can be formed from the wood fiber pulp lump 1 as follows. First, as shown in FIGS. 1 and 2, when the pulp mass 1 is put into the rotary cylinder 12 of the fiber disintegration unit 10 through the conveyor 11 from the pulp inlet 12 </ b> A, a large number of claws are formed in the rotating rotary cylinder 12. While being moved by 19, vibration is given by the vibration plate 17 and the fine vibration plate 18 to disintegrate. The pulp mass 1 moves to the pulp outlet 12B by the wind of the blower 13 while being defibrated in this way, and is sent to the fiber beard 20 in the next step through the defibrated fiber guide flow path 21A. At this time, the inclination of the rotary cylinder 12 also helps the movement of the pulp mass 1 and the defibrated fibers 2.

As shown in FIGS. 1 and 3, the defibrated fiber 2 is sent from the defibrated fiber inlet 21 through the defibrated fiber guide channel 21A to the beard piercing portion main body 20A at the fiber beard portion 20. In the process of passing between the rolls with surface grooves 22 and 23 in the main body 20A, so-called bearding is performed. At this time, the amount of beard and the amount of processing (processing speed) are adjusted by adjusting the rotation speed of the rolls 22 and 23 and adjusting the gap between the rolls 22 and 23. Then, the bearded defibrated fibers (beard defibrated fibers) 2A are sent from the feed pipe 27 to the paper layer forming section 30 in the next step.

In the paper layer forming section 30, as shown in FIGS. 1 and 4, the bearded defibrated fibers 2A are stably placed on the moving blanket 3 in a uniform band shape by the guide of the guide plate 31. The diluted starch 32A is sprayed into the aggregate of the bearded defibrating fibers 2A placed on the moving blanket 3 in a shower shape by the moisture imparting mechanism 32 to supply moisture and starch to the bearded defibrating fibers 2A. At this time, the water content is kept to a minimum. The bonding of the individual fibers is promoted by the supply of water, the mutual bonding force between the fibers is increased by the starch, and the scattering of the fine fibers which are the fiber beards on the front and back surfaces of the formed paper sheet is prevented.

Further, as shown in FIGS. 1, 4 and 5, the paper sheet on which the paper layer has been formed is sent to a paper forming section 40, where it is heated and compressed by a heating roll 41 and a pressure roll 42. You. Then, the fiber-to-fiber bonding force is enhanced by compression, and drying is performed by heating to evaporate the water provided by the water supply mechanism 32, thereby forming a predetermined paper sheet 2B. The moisture content of the formed paper sheet 2B is about 3 to 8%.

Thus, in the present dry paper forming apparatus,
Without using water (including liquids other than water), the pulp 1 is defibrated and the defibrated fibers 2 are bearded by mechanical processing, and paper is formed using only a small amount of water when forming the paper layer. Since the layer is formed, the amount of water required for paper formation can be significantly reduced, and the burden on various facilities (water treatment facilities, water supply facilities, etc.) due to the large amount of water used can be reduced. It is environmentally preferable, and energy consumption for moving water can be significantly suppressed.

Also, since the removal of water is simplified, there is an advantage that the paper forming line can be shortened (that is, the apparatus can be reduced) and the paper forming processing time can be shortened. In addition, when the paper layer is formed from the defibrated fibers, the diluted starch 32 is formed by the shower 32 as a moisture imparting mechanism.
By supplying A to the beard disintegrating fibers 2, the bonding between the fibers is promoted by the moisture, and the adhesiveness such as starch enhances the mutual bonding force between the fibers and forms the paper sheet. It is possible to prevent the generation of fine fiber droplets on the front and back surfaces, and it is possible to sufficiently secure papermaking quality.

The present invention is not limited to the above-described embodiments, but can be implemented with various modifications without departing from the gist of the present invention. For example, at the time of fiber disaggregation, a small amount of moisture may be added if moisture addition is effective in addition to mechanical processing. But,
In any case, the disintegration of the fiber is mainly performed by mechanically applying a force to the pulp mass. Since the water added here is auxiliary, the use of the water is suppressed and the disintegration of the pulp 1 and the disintegration of the disintegrated fiber 2 are performed. It is needless to say that the bearding is performed, and the above-described effect by reducing the use of water can be obtained. Although not particularly described in the present embodiment, it is also preferable to perform a process such as dust removal before and after fiber bearding.

[0041]

As described above in detail, according to the dry paper forming apparatus of the first aspect of the present invention, the fibers of the pulp are defibrated by mechanical processing without being mixed with water and defibrated. Since the fibers are bearded by mechanical processing without relying on moisture, the amount of moisture required for paper formation can be significantly reduced. Therefore, it is possible to reduce the burden on water resources (water treatment facilities, water supply facilities, and the like) due to the large amount of water used, which is favorable in the global environment, and also significantly reduces energy consumption for moving water. can do. Further, since the removal of water is simplified, there is an advantage that the paper forming line can be shortened (the apparatus can be reduced) and the paper forming processing time can be shortened.

According to the dry paper forming apparatus of the present invention, the pulp fibers can be easily and reliably disintegrated without using water. According to the dry paper forming apparatus of the present invention, the paper layer can be appropriately formed only by applying a small amount of water (including a liquid other than water), and the amount of water required for paper formation can be reduced. A predetermined papermaking quality can be ensured while significantly reducing the amount. Therefore, by greatly reducing the amount of water, the burden on water resources can be reduced, the energy consumption for moving water can be significantly suppressed, and the removal of water is simplified, There is also an advantage that the shortening of the paper forming line (reducing the size of the apparatus) and the shortening of the paper forming processing time can be promoted.
