Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention, in the straining process when manufacturing recycled Japanese paper, stirs the stock liquid in the straining tank and strains the stock with a wire mesh, and after straining, draining from wet paper, dehydration work, The present invention relates to a simple paper making device for reusing Washi-style recycled paper, which automates.

[0002]

[Prior art]

 In general, Japanese paper-like recycled paper manufactured using pulp from used milk packs as the main raw material is peeled from the polyethylene film layers on both sides of the milk pack, and then finely crushed while soaking in water, and then beaten the fibers well. Add water and dye to make a thick stock solution. This is further made into a stock solution with an appropriate concentration while being diluted and turbid with water in a strainer, and the stock solution is manually lifted by a wire mesh while manually stirring the stock solution. The wet paper layer, which has been fried on a wire mesh, is placed on the opening of the dehydration box after draining by natural dripping, and dehydrated while keeping the inside negative pressure with a household vacuum cleaner etc. We make a piece of recycled paper with the texture of, and based on this recycled paper, we make handicrafts such as postcards, stationery, envelopes, business cards, and coasters.

[0003]

[Problems to be solved by the device]

 However, in the process of making the recycled paper, it is difficult to lift the stock to a uniform thickness from the diluted and turbid stock liquid in the strainer, especially when making large size paper. It required physical strength and skill, and there was a difficult problem in producing a product of constant quality.

As for the production of original Japanese paper (handmade Japanese paper made from plant bast fiber as the main raw material, such as Japanese pomegranate, Japanese pepper, goose bark, etc.), it can be fried in the same way as manual work. There is an automatic paper making device (see, for example, JP-A-59-211698, JP-A-3-174087, JP-A-5-86595, and the like), but a small handicraft-like product is made. This is too large as a device for making recycled paper. Also, when straining washi, the method of swinging the cage girder back and forth and left and right to entangle the fibers of the paper stock is also unsuitable for frying the recycled paper due to the difference in the quality of the two. .

Therefore, it is an object of the present invention to provide a simple paper making device for recycled Japanese paper, which aims to solve the above-mentioned problems, by a method using a relatively simple mechanism.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the paper making device according to the present invention firstly provides a large number of holes that reciprocate back and forth in the paper making layer in order to sufficiently cloud the paper solution in the making tank. The stirrer plate (see JIS P 8209 Perforated Plate Stirrer) was hung and fixed in the tank through the connecting rod of the drive mechanism installed outside the tank, and gently and once at a constant speed. Reciprocate about once to stir the stock solution.

After stirring, the straining girder to which the wire mesh is fixed is immediately mounted on the upper side of the straining girder holding frame located in the upper part of the filtering tank. The holding frame has a frame shape with an open upper part and a lower part, and the upper opening facilitates the attachment and detachment of the straining girder. It is equipped with rubber packing for holding. In addition, there is an air suction port at the center of the rear side of the frame, and it is connected to the air suction machine installed outside the equipment with a flexible hose, and on both sides of the frame, the lifting mechanism built outside the polishing tank is used. It is connected and supported by the arm. While holding the holding frame equipped with a strainer girder horizontally and gradually descending to a set position (point C in Fig. 3) in the straining tank at a constant speed, immediately after lifting and stopping the stock, the stock solution When it is moved up to the set position in the plane (point D in FIG. 3), a wet paper web layer having a uniform thickness is formed on the upper surface of the wire mesh.

Next, after draining water by natural dropping while the holding frame is stopped for several seconds, excess water contained in the wet paper web layer is dehydrated. The dehydration method is such that when the holding frame is raised, the lower opening of the holding frame, that is, when the bottom of the frame reaches a position just outside the liquid surface of the stock (point D in Fig. 3). The bottom of the frame and the liquid surface of the stock overlap each other to form an airtight wall. By activating the air suction device, it is possible to perform dewatering while maintaining a negative pressure inside the holding frame.

[0009]

[Embodiment of the invention]

 An embodiment of the invention will be described based on an example with reference to the drawings. 1 to 3, a filtering tank 2 is fixed to a lower portion of a frame 1 in which a hollow column having a square cross section is assembled into a cubic shape. The strainer tank is such that when the strainer girder holding frame 4 to which the strainer girder 5 is attached is lowered to the lowest position in the strainer tank, point C in FIG. 3, the liquid level in the tank is the upper surface of the strainer girder 5. It has a depth that allows it to be positioned sufficiently higher.

Reference numeral 3 is a stirring plate, which is formed of a four-sided thin plate having a large number of round holes, is operable without contacting the inner wall of the shaving tank, and is sufficient for stirring the stock solution. It has an area and is fixed by hanging to the connecting rod 31. The connecting rod 31 is fixed to the drive chains 33a and 33b by screws so that the connecting rods 31 can be fitted and slid on the guide rods 32a and 32b respectively installed on the left and right outer sides of the filtering tank 2. The agitator drive motor 34 causes the connecting rod 31 to reciprocate back and forth through the shaft 35 and the sprockets 36a and 36b to agitate the stock solution.

As described in the paragraph “0007”, the strain girder holding frame 4 includes a metal stopper 42 capable of easily attaching and detaching the strain girder 5 to the upper opening, a rubber packing 42 for keeping airtight with the strain girder, and a rear portion of the holding frame. It is composed of an air suction hole 43 on the side surface and a flexible hose 45 connected to an air suction device 44 installed outside the apparatus. The mechanism for raising and lowering the straining girder holding frame 4 horizontally fixes both side surfaces of the straining girder holding frame 4 to the arms 47 a and 47 b which are moved up and down along the guide columns 46 a and 46 b installed at the rear of the straining tank 2 with screws. . A feed screw 48 is vertically provided at a position passing through the left and right center portions of the arm, and a female screw 49 fitting and sliding to the feed screw 48 is fixed to the arm side. Therefore, it is possible to add a function to set the speed of raising and lowering and the stop position arbitrarily.

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

In the simple paper making apparatus for recycled Japanese paper according to claim 1, since the stirring of the stock solution in the making tank can be automatically performed at a constant speed and always under the same conditions, it is performed by a palm or a plate of a human hand. The turbidity of the stock and water is better than that of stirring, and it contributes largely to the reduction of the time required for stirring and the uniformity of the wet paper web layer during frying.

In the simple paper making device for recycled Japanese paper according to claim 2, since the straining girder can be automatically moved horizontally and always under a constant condition, the wet paper web layer lifted can keep a uniform thickness. Therefore, it is possible to reduce the degree of skill and fatigue of the operator as compared with the case of handmade. In addition, when the wet paper web layer is dehydrated, the straining girder holding frame functions as a dehydration box, and a dehydration box, which is conventionally required separately, is unnecessary.
