DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a papermaking method and apparatus suitable for producing a friction material stretched on a friction plate incorporated in, for example, a clutch device which is one of transmission devices.

[0002]

BACKGROUND OF THE INVENTION For example, a clutch plate for a vehicle, in particular, a friction plate in a wet multi-plate clutch has a structure in which friction materials are stretched on both surfaces of an annular metal friction plate body. As the friction material, instead of a molded material such as a conventional resin mold, at present, a sheet made by mixing various friction materials with a pulp material and using a papermaking technique has been used as a starting material. By the way, even in such a method, conventionally, a friction material sheet is cut out into a required shape, for example, an annular shape after forming the material sheet with a fourdrinier paper machine or the like. However, of course, the yield is extremely low in such a method.
As disclosed in JP-A-91294, there has been proposed a method in which a friction material is formed into a necessary annular shape from the beginning. However, the disclosure of this prior art basically focuses on making the product into an annular shape, and does not provide enough technical matters to be overcome when actually making such an annular member. No disclosure. In other words, what is problematic when making such an annular paper is the properties of the material fibrous material at the edges, and this portion tends to be uneven in thickness and thickness as compared with other portions. If it is not eliminated, it cannot be a product that can withstand practical use. For this reason, in the above-mentioned prior art, as disclosed in the specification, furthermore, a punching process is required in order to adjust to a precise size as a product. In the case of such a friction material, unlike a normal paper, the punching process is performed because a material having a high abrasion resistance while ensuring a frictional action, such as diatomaceous earth and calcium carbonate, is mixed. As a result, the cutting tool to be machined is remarkably quickly worn, and as a result, it has not yet been put to practical use.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and has attempted to develop a method and an apparatus which can perform precision papermaking to a predetermined shape at once.

Next, the operation of the above-described papermaking apparatus 1 will be described. i) Preparation of raw materials First, as a raw material, since the final product is a friction material for this kind of clutch plate or the like, asbestos, organic fiber,
A material suitable for the intended use, such as carbon-based or ceramic-based inorganic fiber, short metal fiber, diatomaceous earth, calcium carbonate, etc., and further mixed with a thermosetting resin or impregnated in the raw material. in mixing in the raw material liquid a _0. The raw material liquid A ₀ is _supplied to the main raw material tank 11.
Auxiliary raw material tank and a 12 to that filled in, so achieving sequential from the auxiliary raw material tank 12 in the case where for example the raw material liquid A ₀ of the main raw material tank 11 falls below a predetermined amount so as to replenish the raw material liquid A ₀ and is there.

It is to be noted that this kind of friction material has a relatively large specific gravity and a small particle size, such as the above-described inorganic filler, and these portions are simply lowered when stored. It is preferable that both the main raw material tank 11 and the auxiliary raw material tank 12 are provided with a stirrer 15 so that the raw material is constantly stirred during the operation. Specifically, the propeller 18 in the stirring device 15 is
Is driven by, it is the raw material liquid A ₀ always tank is agitated.

[0027] ii) retrieving quantitative extraction thus the raw material liquid A ₀ prepared by a constant amount in order to send the next papermaking process. The removal capacity required amount according to the specifications of the product A ₁ is indexed to be prefabricated, this is to incorporate a certain amount to the metering mass 21.
That is, the volume of the measuring chamber 22 in the measuring mass 21 is adjusted by adjusting the adjusting piston 24 in the capacity adjusting device 23 to the adjusting dial 2.
By rotating 6, the state of protruding and retracting into the measuring chamber 22 is appropriately adjusted, and the volume of the measuring chamber 22 is adjusted to a predetermined capacity. Then, with the volume of the measuring chamber 22 set in this way, the valve device 28 is operated, and the raw material liquid A ₀ is taken into the measuring chamber 22 from the main raw material tank 11.

First, when the measuring mass 21 and the main raw material tank 11 are not in communication, the valve stem 29 of the valve device 28 is shifted downward by the shift of the valve shifter 30. In this state, the lid
State Bed 31 which opens prevents the inflow of the liquid raw material A ₀ from substantially the main raw material tank bottom surface in which the upper valve in close contact with the sheet 33 the main raw material tank 11 of 11, a pouring opening 36 in the outlet chamber 35 Is set to By shifting the valve shifter 30 from such a state, the valve stem 2
4A, the upper valve 31 is opened upward and the lower valve 32 is opened as shown in FIG.
Closes the inflow port 36 above the outflow chamber 35 in close contact with the lower valve seat 34. Is the raw material liquid A ₀ flows into the metering chamber 22 of predetermined volume measuring mass 21 from the upper valve 31 which is opened when this way.

After such a state, the valve shifter 30 is operated again as shown in FIG.
9, the upper valve 31 is moved downward.
Adhesion between the upper valve seat 33 is achieved in the lowered weighing the mass 21 of material liquid A ₀ from the main raw material tank 11
Block the inflow to On the other hand, the lower valve 32 is separated from the lower valve seat 34 to open the inlet 36,
The raw material liquid A ₀ leads to the outlet chamber 35 from here, since further partial discharge was removed quantify material liquid A ₀ in papermaking cup 125 in the papermaking main device 100 via a metering pipe 40 from the outlet 37 with a metering mass 21 is there.

Of course, at this time, the air blowing pipe 2 is
By air constant pressure is blown from 7, it is the aim to flow out of the raw material liquid A ₀ can be smoothly performed. Then, if necessary, a part of the cleaning liquid using tap water or the like is separately supplied from the cleaning port 38 to clean the raw material liquid A ₀ , particularly the lower valve 32 and the lower valve seat 34, and further, the periphery of the inlet 36. Things. Of course the cleaning liquid of the remainder is sent in a state such as mixing with a raw material liquid A ₀ from the dispensing tube 40 to the next step.

[0031] iii) papermaking papermaking body raw material liquid _{A 0} coming supplied in this manner apparatus 1
Receiving papermaking cup 125 in 00, it is to papermaking product _{A 1} of a predetermined shape. First papermaking head 120 in the paper-making body device 100 in the step of receiving a supply of the raw material liquid A ₀ is a state where the lower surface thereof to the carrier net 113 papermaking head top 121 is lowered sufficiently in contact, whereas, papermaking head lower 141 rises and also abuts on the carrier net 113 from below, and the upper and lower heads 121 and 141 of the papermaking head are substantially set in a state where the respective opposing surfaces are in close contact with the carrier net 113 interposed therebetween. I have.

In this state, the papermaking is started.
The raw material liquid A ₀ before so as not to suddenly flow down it, as if the supported liquid L to underpin the liquid supply pipe 148
A fills the drainage chamber 147 from A. That is, the switching valve 149
The liquid supply pipe 148A is brought into the “contact” state with the liquid supply / drain pipe 148, and the drain pipe 148B is brought into the “disconnected” state, so that the supporting liquid L flows in, and the level is set to be near the carrier net 113.

The flowing a certain amount of raw material liquid A ₀ from the dispensing pipe 40 in this state during papermaking cup 125 disposed on the papermaking zone 110A. Until the inflow is complete when accordingly, material liquid A ₀ maintains the state of being propped up by the support liquid L. Thereafter, when the switching valve 149 is shifted and the supply / drainage pipe 148 communicates with the drainage pipe 148B,
Together with the support liquid L starts to flow out from here, it is to spontaneously flow out material liquid A ₀ and subsequently. That is, the lower part of the papermaking cup 125 is connected to the drain hole 14 in the perforated plate 146 of the lower part 141 of the papermaking head via the carrier net 113.
6a, so that the raw material liquid A is successively. The liquid component a therein flows down from the drainage chamber 147 of the lower part 141 of the papermaking head through the carrier net 113 and the drainage hole 146a, and is taken out from the supply / drainage pipe 148.

When this state is continued for a certain period of time, the product component A ₁ in the raw material liquid A ₀ ( the product component A ₁
Product A ₁ and the Charles substantially the cat in the same way on the Shimesuru
In indicated by common reference numerals A ₁₎ comes is Shoshutsu on the carrier net 113 form a web-like layer of constant thickness. After the layer having a certain thickness is thus formed, the valve 151 of the forced drainage pipe 150 in the lower part 141 of the papermaking head is opened, and the liquid component a in the papermaking cup 125 is forcibly discharged therefrom by vacuum suction. It is designed as follows. By the way, the natural flow is almost several seconds, and the forced drainage is about twice as long as a total of about 10 and several seconds, which is a working process (see FIG. 11).

[0035] In this manner performs gravity flow fixed time, followed by the forced discharge can be made uniform product quality A ₁ that is molded on the carrier net 113. That is, the product component A ₁ is Shoshutsu on reasonably carrier net 113 by gravity flow, product ingredients as this thing is tentatively forces out product component A ₁ of residual
The effect of preventing the outflow from the carrier net 113 of A _1, is the resulting homogeneous product can be efficiently produced. On the other hand, in the case of forcible discharge from the beginning, FIG.
Product Component A ₁ is mixed in a mesh of the carrier net 113 (a), the or clogged, the product component A
₁ will be incurred.

Furthermore distributed projections 129 with the raw material liquid A ₀ acts to flow out evenly in the circumferential direction, the sectional shape of the outflow molded hole 130 as narrowed upward slightly as shown in FIG. 12 (a) It has a shape, with each other to less slightly occurrence of stacked prone product components a ₁ upward along which the boundary side wall portion 130a, 130b of the outer and inner. Incidentally, as shown in comparison with FIG. 12B, the boundary side wall portion 13 in the outflow forming hole 130 '.
0'A, now edge of product A _'1 bulges coming being papermaking there are when the shape of 130'b is vertical, only some parts thereof in the final product is locally thick product It will be.

After the papermaking is completed in such a state, the papermaking head upper part 121 and the papermaking head lower part 141 move so as to be separated from each other. That is, the upper part 121 of the papermaking head
In response to the operation of the shift cylinder 124, the slide frame 123 is raised and the lower contact surface 132
