Description

  The present invention relates to a paper making apparatus for making handmade sheets suitable for handmade cards such as postcards, business cards, etc., and sheets of A3, A4, etc. Is.

  Raw material paper such as milk cartons use high quality pulp materials due to their properties, and their collection is promoted from the viewpoint of effective use of resources. As an attempt to further advance this viewpoint and actively reuse this product, it is also part of hobbies to redefine the milk material of the milk pack and spread out handmade postcards. Such a craftwork is also suitable as a work theme in a work place, a delivery facility, etc. for people with physical and mental handicap, and many facilities are working on the production of products that reuse milk cartons. Such work facilities sell postcards etc. that reuse these milk cartons as products of each facility, helping profits, and as part of enlightening workplace activities.

  In such a case, the quality is inevitably required when considering that it is a product intended for the general public, although it is based not only on the satisfaction of the work created by itself. In many cases, the skills and training of workers continue to produce products that can fully meet quality requirements. However, the desired quality cannot be obtained depending on the degree of obstacle of the worker, and as a result, the confidence and motivation of each worker is reduced. Such a situation that occurs because the work created by the operator is positioned as a product should be avoided from the essence of the work place, and for that purpose, a process that requires some skill is required. It is also a plan to leave it to machine operation. However, at present, there is no suitable apparatus that supports simple mechanization of some processes while mainly carrying out such handmade work.

  In addition, this kind of paper making work itself is sufficiently useful for understanding the principle of the paper making process, and is extremely effective as part of scientific learning for children and students. If a simple device capable of confirming the principle of the paper making operation is realized, it can be expected that, by utilizing the device, scientific interest and motivation for so-called manufacturing will be cultivated for children and students.

Of course, in order to easily produce such a handmade card or sheet, there has also been proposed an appliance that uses a household vacuum cleaner and actively eliminates sprinkling water in the raw material liquid (Patent Document 1).
However, with this conventional method, as described above, it is not enough to devise a method for making paper-making while maintaining a certain quality regardless of the improvement of usability and the skill of the operator. Absent.

The main components are the dehydrating container 6 to be received and the working piping 7 for performing these operations.

First, the machine frame 1 will be described. Considering that this type of device is used in schools, scientific education and enlightenment facilities, handicapped person workplaces, etc. 1 or the like is also preferable. Of course, it is possible to use an appropriate metal material such as an aluminum mold in consideration of strength, durability and the like.
The machine frame 1 is a frame-like member in which a pair of side machine frames 10 having a substantially trapezoidal shape when viewed from the side are provided in a left-right opposed manner, and these are integrated by a shelf 11 provided therebetween. As an example, the shelf 11 includes an upper shelf 11A, an intermediate work shelf 11B, and a lower lower shelf 11C. In addition, the space comprised by the raw material width | variety of the leg part material which the side part machine frame 10 opposes is made into the space 12 between machine frame materials. In addition, it is preferable to provide the steam-water separation safety chamber 4 mentioned later using this part.

For such a machine casing 1, a soot box 2 is provided on a work shelf 11 </ b> B. As shown in FIGS. 3 and 4, the soot box 2 includes a drainage base box 21 and an input container 22 installed so as to be densely stacked above the main box. Both of these are connected via a rear (back side) hinge 23, and a draining container 22 is attached to the drainage base box 21 so as to be freely opened. A packing 24 is provided between the two. The water-tightness at the contact site between the two is maintained.
Further, the drainage base box 21 is provided with a purse net 25 and a clamp 26 is provided on the front side facing the hinge 23 so that the input container 22 is placed in close contact with the drainage base box 21. Configured.
As shown in FIG. 3, when the card-like sheet of a postcard size is drawn out, the card 25 uses a card post net 25a that does not have a partition in the net and uses the entire net surface. On the other hand, when a card-like sheet of a business card size is to be rolled out, a business card screen 25b provided with a partition 25d in the net part and divided into four parts on the entire surface is used. The size of the sheet to be rolled out is not particularly limited, but a sheet of about A3 size, for example, can be used practically.
Further, a drain outlet 27 is provided on the drainage box 21 side of the soot box 2. The drainage port 27 is connected with a water draining pipe 70 which is one of the working pipes 7, and the water draining pipe 70 reaches an air / water separation chamber 3 described below.

Next, the steam / water separation chamber 3 will be described. The steam / water separation chamber 3 is provided by using an upper shelf 11A in the machine casing 1, and has a water collecting hole 32 opened on a side surface of a container-like chamber main body 31, and the water is drained there. One end of the tube 70 is connected.
Further, the chamber body 31 is provided with an intake hole 33 to which one end of the suction working pipe 76 of the working pipe 7 is connected. A flat air / water separator 34 is provided between the water collecting hole 32 and the intake hole 33 in the chamber body 31. Further, a water level setting hole 35 is provided on the side surface of the chamber body 31, and a water level setting valve 36 is provided on the outer side thereof. This water level setting valve 36 is in close contact with the side surface of the chamber body 31 when the inside of the chamber body 31 is sucked from the intake hole 33, and prevents the water L0 from flowing away, and the negative pressure of the intake hole 33. When the suction is stopped, when there is a sufficient amount of sprinkling water L0 in the chamber body 31, it acts as a check valve that receives the water pressure and causes the sprinkling water L0 to flow outside. . A drain rough 37 is provided outside the water level setting valve 36 to receive the spilled water L0. A drain hole 38 is opened in the drain rough 37, and a drain pipe 73 directed to the dehydration container 6 is provided from the drain hole 38. Further, a water return port 39 is opened below the chamber body 31.

Next, the steam / water separation safety chamber 4 provided on the upstream side of the suction working pipe 76 connected to the steam / water separation chamber 3 will be described.
This is provided by using, as an example, a space 12 between machine frame materials having a flat width formed by the machine frame 1. The reason why the air / water separation safety chamber 4 is provided in such a position is to avoid the complicated use in terms of effective use of space and layout. The safety chamber main body 41 of the steam / water separation safety chamber 4 is provided with a suction hole 42 to which the suction operation pipe 76 is connected and a suction hole 43 to be connected to the suction original pipe 75, between which a separation plate 45 is provided.

Further, a drain hole 46 is provided on the side surface thereof, and a drain valve V2 of the operating valve device V is provided in this side, and further, the tip thereof reaches the dehydrating container 6.

Then, for example, a household vacuum cleaner or the like as the suction means 5 is connected to the air / water separation safety chamber 4 via the suction pipe 75. It should be noted that the use of such a familiar material is preferable in that it gives interest to the so-called “manufacturing” to the students who come into contact with it with a familiar impression, and is also preferable in terms of reducing the cost of the apparatus for introduction. Because. Of course, it is possible to use a dedicated vacuum pump.
Further, as already described, the dehydration container 6 for receiving the waste water from the air / water separation chamber 3 or the air / water separation safety chamber 4 is provided, for example, on the lower shelf 11C of the machine frame 1 or the floor around the apparatus.

Next, the working piping 7 will be described. Although some members have already been described, first, the water draining pipe 70 in the working pipe 7 connects the watering box 2 and the steam / water separation chamber 3, and the water from which the pulp component is sprinkled is obtained. This is for recovering L0.
Further, the surplus water drain pipe 71 extends from the drain rough 37 in the steam / water separation chamber 3 to the dehydration container 6, and dewaters surplus in the sprinkling water L0 sucked into the chamber body 31 of the steam / water separation chamber 3. It is a pipe for collecting in the container 6. Further, a diluting liquid return pipe 72 is provided between the air / water separation chamber 3 and the soot box 2, and a diluting valve V1 is provided therebetween. As can be understood from this, the sprinkling water L0 remaining in the steam separation chamber 3 returns to the sprinkling box 2 again and is used for the preparation of the raw material liquid L.
Further, a drain pipe 73 is drawn out from the air / water separation safety chamber 4, and a discharge valve V <b> 2 is provided therebetween, and the spilled water L <b> 0 discharged therefrom is collected in the dehydration container 6.

  On the other hand, the flow of negative pressure air for the purpose of such movement of the water L0 will be described. A suction original pipe 75, which is a suction pipe of a household vacuum cleaner as the suction means 5, is connected to the air / water separation safety chamber 4 to the suction hole 43. On the other hand, the suction operation pipe 76 is connected from the suction hole 42 of the steam / water separation safety chamber 4 to the suction hole 33 of the steam / water separation chamber 3.

  The paper making apparatus A for producing a handmade sheet according to the present invention has the above-described configuration as a basic configuration, and this operation mode will be described below.

<1. Preparation of raw material liquid L>
The raw material liquid L is, for example, used by defibrating and using a material that sufficiently contains a virgin pulp component such as a milk pack, and stores an appropriate amount in the container.
Here, definitions of terms such as the raw material liquid L or the paper raw material components in the raw material liquid L will be described. First, the raw material liquid L is a generic term for raw materials containing the water L0 and the paper raw material component P0. More specifically, a raw material preparation liquid L1 prepared by containing a paper raw material component P0 having a constant concentration, and a diluted raw material having a concentration suitable for receiving the paper by putting it into the burning box 2 The liquid L2 is a general term. Then, the water component is set to water L0, the paper raw material component is set to P0, and the paper-like web P1 is the squeezed-out state. And As for the sheet-like product P, a card-like postcard sheet Pa, a card-like business card sheet Pb, and the like are produced as described later.

<2. Preparation of diluted raw material liquid L2>
First, a raw material preparation liquid L1 prepared by scooping up a predetermined amount with an appropriate measuring cup C is put into the scooping box 2 (see FIGS. 7A and 7B). At this time, the soot box 2 is in a state in which the purse net 25 is provided on the drainage base box 21, and the upper charging container 22 is kept in close contact with the drainage base box 21 by the clamp 26. Note that it is preferable that the net 25 used at this time be exchangeable as appropriate. That is, a postcard sheet Pa or a business card sheet Pb can be selected.
In particular, in order to roll out the business card sheet Pb, since the size is small, as described above, it is preferable to set the size to roll out about four sheets at a time with respect to one sheeting net 25. .

When the raw material preparation liquid L1 is charged in such a state, the concentration of the paper raw material component P0 may be somewhat high when it is sprinkled. For this reason, the dilution valve V1 provided in the middle of the dilution liquid return pipe 72 connected to the sprinkled water recovery hole 32 in the steam-water separation chamber 3 is opened. Thereby, the sprinkling water L0 remaining in the previous step in the steam-water separation chamber 3 is recovered by returning it to the sprinkling box 2 again (see FIG. 7C).
In this state, the diluted raw material liquid L2 is obtained in the whispering box 2, and an operator adequately stirs the diluted raw material liquid L2 in the whispering box 2 with a rod-like or spatula-like stirrer or the like (FIG. 7D). reference).

<3. The beginning
After preparing in this way, as shown in FIG. This activates the suction means 5 to which a household vacuum cleaner is applied, performs negative pressure suction, and sets the inside of the steam / water separation chamber 3 from the steam / water separation safety chamber 4 through the suction working tube 76 to a negative pressure state. As a result, the lower side of the drainage base box 21 in the watering box 2 is brought into a negative pressure state, and the water L0 is sucked. As a result, the sprinkling water L0 is sucked into the steam / water separation chamber 3. At this time, the water level setting valve 36 provided on the side surface of the chamber main body 31 of the air / water separation chamber 3 is kept in a negative pressure state in the chamber main body 31, so that it closely contacts the side surface of the chamber main body 31, The water level setting hole 35 is kept closed. As a result, it is prevented that the sprinkling water L0 flowing into the steam / water separation chamber 3 from the sprinkling box 2 is excluded by the drain rough 37.

Moreover, in the chamber main body 31 in the steam / water separation chamber 3, even if the suction is performed from the side as shown in FIG. 5, the spilled water L0 collected in the chamber body 31 is separated from the steam / water. The body 34 is blocked by the body 34 and stored in order from below, so that the water is hardly sucked into the suction working tube 76 connected to the air / water separation chamber 3. Of course, even if it is partially sucked, it first reaches the next air-water separation safety chamber 4 and is not directly sucked into the suction means 5.
When the suction means 5 is stopped, the water level setting valve 36 is opened as shown in FIG. 7 (f), and the sprinkling water L 0 at a level higher than the water level setting hole 35 is discharged from the drain hole 38. It is stored in the container 6.
Even in the air / water separation safety chamber 4, even if a part of water is mixed in the suction operation tube 76 due to the presence of the separation plate 45 under the same action, the suction source tube 75 is immediately reached. There is no problem in the operation of the suction means 5. Accordingly, the water L0 is not substantially stored in the steam / water separation safety chamber 4, but even if it is present, it is discharged from the drain hole 46.

<4. Removal and finishing of paper-based web>
When such an operation is completed, the paper raw material component P0 is sprinkled out as a paper quality web P1 in the whirling box 2. When the operator confirms the completion of the sowing operation, the operator releases the clamp 26 in the soot box 2, causes the charging container 22 to lie down around the hinge 23, and the top of the net 25 in the drainage base box 21. The paper-based web P1 is exposed, a part of this is appropriately picked up with tweezers and peeled off, and separately placed on the work table 8 or the like.
In the state of the paper-based web P1, since it still contains enough water L0, as shown in FIGS. 7 (g) and 7 (h), the work is performed on the work table to remove the water. . That is, after spreading a water absorbent cloth 81 or the like having sufficient water absorption on the work table 8 or above, a paper web P1 is placed thereon, and a water absorbent cloth 81 or the like having additional water absorption is further provided thereon. Covering and pressing this with a round bar-shaped pressing roller 82 or the like, and squeezing water L0 is performed. Thereafter, the product is appropriately dried over one day to several tens of hours to obtain a product.
