Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a winding and compression method and apparatus for forming a compressible mat-like material 1, such as an insulating material such as glass wool, into a compressed roll shape. It is.

BACKGROUND OF THE INVENTION Compressible mat-like heat insulating materials for buildings are usually produced in the form of strips with a width of 1 m to 2 m, for example.

However, this heat insulating material, especially a fibrous material, has a bulk specific gravity of, for example, 0. (11 to 0.03 TON/m3c7), so reducing transportation costs and warehousing costs for storage is an important requirement.

Therefore, the volume is usually reduced by compressing and winding the material into a roll with a width of 1 m to 2 m, but in this case, the volume becomes extremely large unless the material is compressed with a considerably strong pressure. However, if it is compressed too much, the fibers of the insulation material are destroyed and cannot be restored when used, for example, on a construction site. Therefore, the limit of compression that can restore the material to its original thickness becomes an important issue.

FIG. 5 is an explanatory diagram showing the principle of a conventional winding and compression method and its device, in which (1) is a supply conveyor for feeding the heat insulating material (2) in the direction of the arrow, (3), (4) are two rollers arranged in parallel adjacent to this conveyor (1), each rotating around a fixed shaft, and one of the rollers (4) may be movable in the direction of the horizontal arrow (G). (5) is a roller that can be moved up and down and is placed directly above rollers (3) and (4), and (6) is a roller that can move up and down.
, (4), and (5), which are vertically movable, and the rotation directions of the rollers (3) to 5) are as shown by the arrows. (7) shows a roll formed by winding up the heat insulating material (2).

The conventional winding and compression method and its device are configured as described above. First, the conveyor (1) supplies the insulation material (2) in the direction of the arrow, and the tip of the insulation material (2) passes through the roller (3). At this time, the operator wraps the tip of the 11T8 material (2) around the core metal (8) placed between the rollers (3) and (4). Then the roller (3) or 5)
If you rotate the insulating material (2) in the direction of the arrow, the core metal (8
) can be rolled up while being compressed by a roller (5) that can be moved up and down in a roll shape. Roll at this time (7)
As the diameter of the core bar (6) grows larger, the core metal (6) can gradually move upward together with the roll (5). In this case, as shown by the chain line, the roller (4)
may also be made to gradually move in the direction of the horizontal arrow Fu (G) at the same time. After the roll (7) is completed, the core metal (6) is removed by an operator.

[Problems to be Solved by the Invention] In the conventional winding and compression method and device as described above, a core bar (8) is used at the start of winding, and an operator attaches insulation to this core bar (6). This required inefficient work as the material (2) had to be wrapped around it and finally removed.

Moreover, the roll (7) is 3 of the rollers (3) or 5).
Compress only a portion of the outer circumferential surface with several rollers.

Since the pressure is concentrated in one part, it is difficult to compress it properly, and the roll (7) locally becomes wavy and deformed, as shown by the broken line (7a) in Figure 5, and as a result, the insulation material (2) Rolls with wrinkles or cracks on the surface or which have been completely wound (7
), which causes a problem in that the product is inferior in terms of composition and appearance.

Further, as the supplied heat insulating material (2) is rolled up and compressed, there is also a problem in the winding operation that the - side of the roll (7) protrudes or suddenly pulls out.

The present invention was made to solve such problems, and there is no need to use a core metal at the beginning of winding the roll, and a winding and compression method and apparatus thereof are capable of uniformly compressing the outer circumference of the roll. The purpose is to obtain.

[Means for Solving the Problems] The winding and compressing method and device according to the present invention introduces the feed material into a narrow gap surrounded by a plurality of endless belts and winds the leading end of the material in a spiral shape. At the same time, the spirally wound portion, which expands in diameter, is held by the indented arcuate portions of each endless belt obtained by changing the spacing between the support rollers of each endless belt, and tension is applied to these indented arcuate portions. In addition, the material can be wound into a roll while being compressed from most of the entire outer periphery.

[Function] According to the present invention, by supplying the material into a narrow gap surrounded by a plurality of endless belts, the leading end of the material can automatically start winding into a spiral shape without requiring a core metal, and the material can expand in diameter. The spirally wound portion can be wound into a uniform roll shape while being dispersed and compressed from the periphery by the indented arc portion of the F-labeled endless belt.

Then, as the diameter of this spiral increases, the movable support roller (33) of the first endless belt device (3) is moved to the right and the second endless belt Device(
While moving the movable support rollers (41) and (42) of the first endless belt device (3) to the right and diagonally upward while increasing the interval, the support rollers (32) of the first endless belt device (3), (33) and between the supporting rollers (41) and (42) of the endless belt device (4) of 282, forming an indented arcuate portion along the spiral that expands in diameter, and at the same time forming (3) movable tension rollers (34), (36) and second endless belt device (4)

An even pressing force can be distributed and applied from the surroundings to the spiral of the heat insulating material (2), which is expanded in diameter by being given tension. Thus, at the end of the winding of the heat insulating material (2), the support beams (71), (78) are swung downward and upward by the urging force of the hydraulic cylinders (80), (84), and the winding roll is discharged. I can do it.

By the way, in the above embodiment, there are three belt devices (3),

This is done by arranging and controlling multiple moving devices such as air cylinders, each with an endless bell) (37
), (4B), and (53) to maintain the optimal tension and compress the insulation material (2) with the optimal pressure.

It is preferable to provide a tension measuring device (not shown) and control the tension by moving each roller based on the measurement results. Note that the rollers that move their positions are not limited to those in the above embodiments, and other rollers may be moved.

Furthermore, as described above, at the time of starting the supply of the heat insulating material (2), the endless belts (37a), (46a), (
53) and the auxiliary roller (47a) (H in Fig. 4), and the tip of the heat material (2) is rolled up in a spiral shape. Core metal is no longer required, reducing labor and improving work efficiency.
Furthermore, by controlling the above-mentioned operations in an interlocking manner, it is possible to achieve complete automation until the heat insulating material (2) is in a completed packaging state.

In addition, as mentioned above, the insulation material (2) can be compressed at the desired pressure and rolled up, so it can be compressed strongly to the limit where it can be restored, which was previously impossible. It is also possible to significantly reduce warehouse costs.

Since most of the outer circumferential surface of the insulation material (2) is rolled and compressed while being held by the belt, the pressure is not concentrated on only one part, causing wrinkles and cracks on the surface of the insulation material (2). This has the effect that a high-quality product with an excellent appearance can be obtained without causing any damage.

Furthermore, the width dimension of the supplied heat insulating material (2) is, for example, 2 m.
If you make a device that can roll and compress something,
Even if the insulation material (2) is of any size with a width of 2 m or less,
It can be wound into a roll more uniformly, and there is less tendency for the minus side to protrude or pull out, making it possible to provide a highly versatile device.

In the above description, the case where the present invention is used for winding and compressing a compressible mat-like material such as a heat insulating material has been described, but it goes without saying that it can also be used for winding up other flexible materials.

In addition, two to three V-belt-shaped guides are installed on the roller contact side of each endless belt (37), (48), and (53), and each roller is provided with a groove that engages with the guide. If you do this, each endless belt (37), (
4El), (53) can be prevented from meandering, and even better effects can be obtained.

[Effects of the Invention] As described above, according to the present invention, a compressible mat-like material can be automatically wound up using a plurality of endless belts while applying pressure evenly from the surroundings. Further, since the tension force yJ adjustment mechanism of the endless belt for applying pressure is provided in a distributed manner to each of the plurality of endless belts, it is possible to reduce the size of the apparatus without requiring an excessive pressing force.
