Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a long thin plate-like object such as an H plate, a thin film, or a tape is simply folded to form an air layer in the thin plate-like object.

Conventionally, it has been common practice to stack a large number of thin plates one by one using a stacking machine. Therefore, it is inefficient and expensive to produce a multi-layer insulation material by stacking thin films, so alternative insulation materials such as expanded polystyrene and glass wool have been used.These general insulation materials are special. It was not easy to manufacture and was expensive as it required raw materials and equipment.

In recent years, plastic film manufacturing technology has advanced significantly, and ultra-thin films can now be produced with high efficiency and low cost. 0.03mm4#)
It was difficult to fold them together, and it was also difficult to stack them and perform various processing to make them into heat insulating materials. Moreover, plastic films with surface treatments (e.g. uniaxial stretching, corrugation, splitting, fluff adhesion, etc.) are not easy to handle.
Stack a large number of sheets efficiently, and if necessary,
Those placing inserts in IJ'I were particularly difficult.

The present invention can produce approximately 5 to 500 sheets in one process or a small number of processes11 (
``It is an object of the present invention to obtain a device f# suitable for efficiently folding stacked thin plate-like objects.

Conventionally, folding a string or tape-like object in a rake-like manner using a pair of upper-tooth-shaped tools has been known to result in both string and tooth damage.
There was a lot of friction from the river, and it was only possible to stack a few strong dog strings on top of each other.

The present invention is applicable to thin plate-like materials with flatness (including cloth-like materials with low air permeability), tapes, textured surfaces, adhesion processing such as fluff, etc.
Items with a rough surface finish, etc., are available for purchase at JPY 7.
', Lk-f, air is supplied to the contact/sleeve part of the rod-shaped (or plate-shaped) object (1) that is the contact part with the liquid-added rod, and the friction is reduced by at least partially floating the workpiece. west,
Even if it is a film-like material with low strength, it is possible to fold a large number of sheets even with a small amount of power and a small mechanical strength of g+1.

To explain the present invention with reference to the drawings, in FIG. 1, a pair of members having an air supply structure and a rod-shaped (or plate-shaped, hereinafter the same) folded portion are folded and overlapped. Then, the surface becomes as shown in Figure 2.

Served. The strength of the thin plate material against the air supply is insufficient.

, or 11 /4 in the case of large permeable cloth, perforated membrane, etc.
A strong and flexible auxiliary film may be applied to both or one side of the crushed material to remove the molding diameter.

During the folding process, the thin plate-like material (for example, a film, hereinafter referred to as film) 4 is exposed to the air or gas (
The passage 18 (hereinafter referred to as air) is supported by the sliding air layer 16 formed by the air blown out from the air outlet 15 provided on the surface of the draw rod, and due to its low friction, it can be smoothly and The material is drawn out multiple times without the need for significant tension, expanding the area and completing the process at a predetermined length.

Next, if necessary, grab the film from the outside 7
or (and) 17. Remove the rods 2 and 3 and support them while keeping the film stretched by a support member 8, which may be a support of a film tensioning device or a part of the film product. While removing or moving the tool or support member 8, the film is folded using a holding tool 14 which may be a suction type.

In the second screen 1, the blade 6 for cutting the film (it may be cut with heat or other heat) is in the cutting position before the pressing down process by the presser 14, but after the stick is pressed down, the rod is pulled out. In this case, the member 2 may be returned to its original position. Regarding the member 3, as shown in Id1 Fig. 4,
It may be rotated by the shaft 10 and extracted, or it may be extracted laterally as shown in FIG. Alternatively, as in 2, it can be run in the folding direction and extracted. However, if there are spacers or other items to overlap between the films, it is easier to insert them and then pull them out laterally.

(The wire, backing, which is a supporting member only near the folded edge,
When inserting a wedge or the like, it is convenient to use a rod as shown in FIG. 7 or 9, which is made up of two rods and can be pulled out in both directions or in one direction. ) Among these, the rod of the shape shown in FIG. 7 that can be pulled out in both directions can be made into a device in which the folding process is combined with the process of inserting the insert at the same time. I'm going home. (A suction type force member is suitable.) In Fig. 4, the suction fixture 7 or 17 is a vertical type with a suction end arranged in accordance with the position of the rod, but it is horizontal and has the same number of horizontal arms as the rod. It may also be done by If the movement of member 2 or 3 is obstructed, it is natural that it may be operated by pulling out or rotating as in mechanism 2 or 3 so as not to interfere with other processes.

A component can be added to glue or weld the folded portion.

In this case, a bonding or welding device corresponding to position 7 or 17 may be installed. At this time, the wire, thread, or backing may be inserted and then encapsulated and bonded or welded, and the side portions of the film may also be processed in the same way.

The member 7.17 for gripping and fixing the film is a six-piece member, and it is also possible to make this member act to solidify the folded portion of the film.

In this case, as the linear member 8, a member having a wedge-shaped cross section is inserted into the inside of the folded end, and then the wedge is press-fitted with a rod. 5 shows a cross-section of a folding rod-shaped article 1 having a porous outlet or a gap on one side where the film contacts.

When reciprocating and using both sides as shown in Fig. Ag13, it is natural that an air outlet is required for the pipe closure.

FIG. 6 is a cross-sectional view of a rod-shaped $1 manufactured by sintering, fusing, or adhering solid particles. Usually, a gas dispersion material, a gas dispersion material, or a material manufactured as a strainer can be selected and used, allowing for uniform dispersion. The material can be arbitrarily selected, such as stainless steel, carbon steel, copper alloy, plastic, etc., but when the rod is long, it is preferable to use a metal rod or reinforced plastic. This is because if the rod is deformed, the tension on the film tends to become uneven, which may cause deformation of the product or make it impossible to work due to film breakage.

Figure 7 shows two parallel bars as one rod, and Figures 8 and 9 show cross sections of bars with reinforcement 23.It goes without saying that various cross sections can be used for reinforcement. The air blowing portion and the air blowing portion may be made of the same material.

In the above, the shape of the rod or the air blowing part has been given as an example of a circular cross section which is easy to manufacture, but it may also be oval, square, rectangular, other irregular cross sections, or flat. Further, although an example has been shown in which the inside of the rod is used as a ventilation pipe for supplying air, an air supply pipe may be provided along the rod.

Fig. 1O shows an example in which the entire surface of the leaf rod is not an air outlet, but only the main point is provided with an air outlet 11. Fig. 11 shows an example in which a notch is provided in the member 2 or 3 corresponding to the space 22. Depending on the conditions, this may also be a hole.

Figure 12 shows an example of a device for laterally extracting the rods 1 at the end of the folding process, with the advantage of having a drive mechanism attached to the running 2 or 3.

413 Il+ shows an example of the combination of member 2.3 of high-efficiency@sakaki that uses both reciprocating motion for folding.

FIG. 14 shows a mechanism separated from the apparatus that, when cutting the upper part of the film, pulls the terminal at the upper part between the scissors 2o driven by the pulley 19 and pulls it to the fastener 5 at the lower part of the apparatus.

In the explanation of the figures, top, bottom, left, right, etc. are provided for convenience, but it goes without saying that the positional relationship can be changed arbitrarily when implementing the present invention.

It goes without saying that the direction in which the spacer or the like is introduced between the films can be determined as desired.

In this way, the present invention folds air (or gas) into a thin plate-like nose to reduce the frictional resistance of feeding.
i take gas) By using it as a fluid lubricant, 1
This makes it possible to fold an unusually large number of sheets and stack them one on top of the other. As a result, an inexpensive film-sprayed l-≠4 material can be supplied to applications that were conventionally expensive and not necessarily economical to use, thereby increasing the effect of energy saving and alternative energy charging.

3. In particular, the placement of the main body, heat storage tank, and distribution costs of solar water heaters, which have a small amount of heat accumulation and thus a small amount of heat loss greatly affects efficiency, makes it possible to produce high-efficiency mass production using FD. It is.
