BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing a chopped fiber cement board used for producing a thin chopped fiber cement board such as a flat roofing material, and the like. TECHNICAL FIELD The present invention relates to a method for manufacturing a fiber-cement board which is divided into pieces using an apparatus.

[0002]

2. Description of the Related Art A thin plate-shaped small fiber cement board mainly composed of cement and reinforcing fiber material is lightweight, and recently, demand for it as a roof material for buildings has been rapidly expanding in place of Japanese roof tile and cement roof tile. I am doing it. When manufacturing a small fiber cement board, first, a wet method of forming a sheet by forming a slurry in which water is dispersed in a raw material mixture, or by supplying the raw material mixture in layers on a forming belt and adding water. From a forming sheet obtained by a dry method in which a sheet is pressed by a roll to form the sheet, etc., as shown in, for example, JP-A-4-44811, a small fiber cement board as a final product (for example, a flat roof The product material having a size slightly larger than the size of the material) is cut, and then the product material is subjected to primary curing and then the excess portion is cut off by a punching device such as a punch die set to punch out the product shape, which is then autoclaved. It is cured to obtain a small fiber cement board.

The cutting of the product material from the forming sheet is usually performed on a sheet sent by a conveyor having a horizontal conveying surface by using a roll cutter, and the roof of the original sheet is punched in the longitudinal direction. It is performed in the longitudinal direction of the material, and punching from the product material to the final product size is also performed by a punching device such as a punch die set arranged horizontally.

[0004]

Generally, the forming sheet is an endless sheet, and a wide floor area is required to arrange the forming sheet in the horizontal direction and sequentially cut the product material. Also, the work for primary curing of the individually cut product material, and the work of punching it to the final product size are basically work on a piece-by-piece basis,
It takes a lot of time and effort. Further, it takes a lot of time to carry in and set the product material into the horizontally arranged punching machine.

The object of the present invention is to reduce the labor required for the conventional production work of fiber cement board into small pieces, and also to save the space. Another object is to provide a method for manufacturing a fiber cement board.

[0006]

An apparatus for producing small-sized fiber cement board according to the present invention for solving the above-mentioned problems comprises an apparatus for transferring an elongated fiber cement board, and A long-sized fiber cement plate raw material having a fixed lower surface plate and a movable upper surface plate and conveyed from the original material conveying device is received between the lower surface plate and the upper surface plate, and is cut into small pieces from the original material. At least a punching device adapted to punch the formed fiber cement plate, wherein the transport surface of the raw material transport device and the surface of the lower platen of the punching device are inclined with respect to a horizontal plane. It is characterized in that it constitutes a conforming body passage, and that the elongated fibrous cement board original body can be moved by its own weight from the conveying surface of the conforming body conveying device to the lower surface plate surface of the punching device.

[0007] According to this apparatus, the passage of the long fiber cement board original body in the apparatus is a surface inclined with respect to the horizontal plane, and the original body moves to a predetermined position of the punching apparatus by its own weight. To do. Therefore, it is possible to not only reduce the installation floor area of the manufacturing apparatus, but also to omit the mechanical device and human work for transporting the raw material from the raw material transporting device to the punching device. Compared with the case of horizontal movement, the movement mode of self-fall due to its own weight has a good production efficiency because it falls at the moment it is punched into the final product,
Moreover, the merit of labor saving of power is brought.

[0008] In a preferred aspect, the manufacturing apparatus further has a control means for controlling the moving speed of the raw material on the upstream side of the punching device in the raw material passage.
This control means may be a braking roll that can be pressed against the surface of the conformal body, whereby the falling speed of the conformal body is limited,
It is easy and reliable to position the raw material at a predetermined position between the lower surface plate and the upper surface plate of the punching device. Further, the control means may be a means for pressing the raw material body toward the passing road surface so that the raw material body does not move unnecessarily while the punching device is performing the punching process.

[0009] In a further preferred aspect, a receiving device for receiving the chopped fiber cement board punched by the punching device and falling by its own weight is provided on the downstream side of the punching device. The cut fiber cement board after punching is transferred to a subsequent step such as a curing step, but by providing this receiving device, the transfer becomes easy.

[0010] In a further preferred embodiment, the manufacturing apparatus has one or both ends of the raw material or the crushed fiber cement board punched from the raw material, on the downstream side of the raw material conveying device in the raw material passage. It further has a separation mechanism for lifting the part from the road surface passing through the conformation body, thereby promoting the separation of the two. In principle, the long fiber cement plate raw material is press-punched between the lower surface plate and the upper surface plate of the punching device, and in principle, the split fiber cement plate after punching and the surrounding raw material part By opening the mold (lifting the upper platen), the fiber-cement board that has been chopped into pieces is easily separated from the higher-grade raw material part and spontaneously falls by its own weight. You can get out of the device. However, if the punching is insufficient (it tends to occur when the punched object is an uncured fiber cement board), the crushed fiber cement board may not separate from the original part depending on its own weight. It can happen. The above-mentioned separating mechanism ensures that case, and by operating the separating mechanism after opening the mold, it is possible to ensure the natural drop of the punched split fiber cement board.

The separating mechanism may be any means capable of lifting the raw material portion or the end portion of the punched split fiber cement board from the raw material passing road surface, such as a reciprocating piston rod and an eccentric rotation. It may be mechanical means such as a moving cam, or fluid means such as ejection of fluid from a fluid nozzle.

As a method for producing an improved split fiber cement board, the present applicant has shown in FIG. 11 that a raw material mixture mainly composed of cement and reinforcing fiber material obtained by a wet method or a dry method is used. Sheet 1 (forming sheet), in which the reinforcing fiber material is oriented in the longitudinal direction, by a rotary cutter 3 rotating in the arrow direction, cutouts 1 from both sides in the lateral direction before curing.
3 into the longitudinal direction of the sheet 1 as a longitudinal direction to form a continuous raw material 11 of small building board material (small fiber cement board) 12A, and after the raw material 11 is primarily cured, We have already proposed a method for producing a hardened small building board by cutting the small building board of the final product size from the small building board material 12A and curing the separated small building board in an autoclave. (Japanese Patent Application No. 8-18
88596). In FIG. 11, reference numeral 14 is an uncured cut end material, which is used again as a raw material.

The above-mentioned production apparatus according to the present invention can be appropriately used when continuously punching out a plurality of small fiber cement boards from an arbitrary long fiber cement board raw material. As a fiber cement board raw material, in the above-mentioned application, cut out from both sides in the transverse direction before curing, and a long fiber formed by continuously forming a split fiber cement board material with the longitudinal direction of the forming sheet as the longitudinal direction. It works particularly effectively when the original cement plate is used as a material to be punched. Therefore, the disclosure content of Japanese Patent Application No. 8-188596 described above constitutes a part of the disclosure of the present application.

In the present invention, as the raw material of the fiber cement plate raw material, for example, Portland cement, blast furnace cement obtained by mixing Portland cement with blast furnace slag, fly ash cement obtained by mixing fly ash, alumina cement, or the like. Water-curable raw materials such as silica powder, silica powder, silica stone powder, silica fume, diatomaceous earth, and clay powder, and wood-reinforced fibers such as wood powder, wood wool, wood chips, wood fibers, wood pulp, wood fiber bundles, etc. material,
Sepiolite, wollastonite, reinforcing fiber materials such as inorganic reinforcing fiber materials such as glass fibers, and if desired, a mixture of perlite, shirasu balloon, expanded shale, expanded viscosity, lightweight aggregates such as coal husk is used. It In the above mixture, the cement is usually 28 to 40% by weight, the fine silica powder is 28 to 40% by weight, the reinforcing fiber material is 5 to 20% by weight, and 3 to 10% by weight when the lightweight aggregate is mixed. used.

In the method for producing the chopped fiber cement board according to the present invention, first, an uncured mat (that is, a long fiber cement board raw material) preferably molded as described above, Preferably, it is mounted on an original material carrier having a stopper at the lower end. After mounting, the fixed lower surface plate and the movable upper surface plate of the raw material punching device are opened, the stopper is opened, and the raw material body is dropped by its own weight and fed into the raw material punching device. The sent raw material collides with the stopper of the raw material punching device and stops at a predetermined position. Preferably, at that time, the control unit for controlling the moving speed of the original body is used to control the falling speed. When the movement of the raw material is stopped, preferably, the control means suppresses the movement of the raw material by pushing the raw material toward the raw material passage, and the upper surface plate is lowered to perform punching.

After punching, the upper fiber slab is lifted up, and the punched small fiber cement board is naturally dropped by its own weight and jumps out of the apparatus. When the separation mechanism is provided, the separation mechanism is operated to ensure separation and drop. The operation of the separation mechanism may be performed every punching,
The operation may be performed only when it is detected by an appropriate sensor that the split fiber cement board is not separated from the original body portion.

After confirming the end of the drop, the stopper and the control means are operated to remove the remaining portion of the long length of the fiber cement plate raw material, and the fixed lower surface plate and the movable upper surface plate of the raw material punching device are again used. And the same process is repeated thereafter. After the punching for one conformer is completed,
Set the next drug substance in the drug substance carrier by appropriate means,
Repeat the same operation. The punched small fiber cement board is subjected to autoclave curing and hardened to be a final product such as a flat roofing material.

The passage L through which the long fiber cement board raw material 11 in the raw material conveying device A, the control means C, the separating mechanism E, and the punching device B passes is as shown in FIG. , A substantially continuous conformer passage L that is inclined at an appropriate angle α with respect to the horizontal plane G (α = 45 ° in this example), and the fibrous cement plate conformation is formed on the conveying surface of the conformer conveying device A. When 11 is arranged, the original body 11 is allowed to naturally fall on the original body passage L to the upstream position of the receiving device D by its own weight.

The raw material carrier A has a large number of rollers 21 arranged in the horizontal direction, and its carrying surface is inclined by 45 ° with respect to the horizontal plane G. Therefore, the transported object on the roller 21 (in this case, the long fiber cement plate raw material 11) naturally falls from the upper left to the lower right in the figure by its own weight. Further, the original material carrier A has a stopper 22 which can be raised and lowered on the conveying surface side. In the standing state of the stopper 22, the fiber cement plate original body 11 is prevented from falling naturally and falls down. The fiber cement board raw material 11 falls naturally.

Further, a braking roller 33 whose distance from the flat belt 32 can be adjusted is arranged above the drive roller 31b, and the falling speed of the fiber cement board original body 11 that naturally falls on the flat belt 32. Is controlled by the rotational speeds of the flat belt 32 and the braking roller 33 in a state where the drive roller 31b is in contact with the elongated fiber cement plate precursor 11. The control means C further includes a pressing plate 34 for backing up the rear surface side of the conveying surface of the flat belt 32, and the pressing plate 3.

5 has a braking mechanism composed of a pneumatic cylinder mechanism 36 for moving up and down, and the movement of the fiber cement plate raw material 11 is stopped by lowering the braking plate 35 and pressing it against the fiber cement plate raw material 11. .

The punching device B has a lower surface plate 41 fixed to a machine frame and a movable upper surface plate 43 slidable along a column 42 standing on the lower surface plate 41. Board 43
A punching upper die 44 is attached to the sheet through a spring 45. Further, the machine frame is provided with a disk 46 that is driven to rotate, one end of an operating rod 48 is pivotally attached to an eccentric fulcrum 47 of the disk 46, and the other end side of the operating rod 48 is the movable upper platen. Four
3 is drivingly connected. The movable upper surface plate 43 reciprocates in the vertical direction by the rotation of the circular plate 46, and in the lowered position, the punching die 48 attached to the punching upper die 44 from the fiber cement plate raw material 11 located on the lower surface plate 41. Punch out a fiber cement board that has been subdivided into the shape (only its contour shape is shown in FIG. 4). As shown in FIG. 4, two punching dies 48 are provided in this example. Further, a stopper (not shown) is provided in the vicinity of the lower end of the lower surface plate 41 so as to be able to move in and out, to stop the fiber cement plate raw material 11 moving downward on the upper surface of the lower surface plate 41 at a prescribed position, and Let it pass.

The punching device B is entirely inclined at 45 ° with respect to the horizontal plane G, and the upper surface of the lower surface plate 41 is
The control means C is arranged so as to form an inclined surface that is substantially continuous with the conveying surface of the flat belt 32. After the punching, the split fiber cement board 12 naturally falls downward due to the rise of the movable upper platen 43. Although not shown, the punch upper die 44 is also provided with an ear break piece 49a extending radially around the punch die 49.

The separating mechanism E is located in the region of the conforming body passage L between the control means C and the punching device B, and has a piston rod 51 and a pneumatic cylinder 52. In the raised position, the fiber cement plate raw material 11 in the raw material passage L is projected above the transport level (see FIG. 3), and in the lowered position, it is retracted below the transport level. ing. In addition, 53 in the figure
Is a guide plate provided at the transport level of the fiber cement plate raw material 11.

The receiving device D is a guide plate 61 arranged at an inclination of 45 ° so as to form an inclined surface substantially continuous with the surface of the lower surface plate 41 of the punching device B, and after the guide plate 61 is conveyed. A flat belt conveyor 62 having a substantially horizontal conveying surface arranged below the flow side, and the flat belt conveyor 6
2 has a small fiber cement board collecting box 63 arranged below the downstream side of the conveyance, and a second flat belt conveyor 64 arranged below the upper end position of the guide plate 61. . As will be described later, the second flat belt conveyor 64 is provided to collect and remove punched end materials generated after punching the split fiber cement board 12.

Next, a method of using this manufacturing apparatus will be described. The long-sized fiber cement plate raw material to be used may have an arbitrary shape according to the punching die of the punching device B. In the following description, the fiber cement plate raw material having the shape described above with reference to FIG. 11 is used. The case of using 11 will be described as an example. FIG. 4 shows the fiber cement board raw material 11, and 10 pieces of the small fiber cement board raw material 12A are provided by a paper making device (not shown), and the longitudinal direction of the fiber cement board raw material 11 is divided into the small fiber cement board raw material 12A. Is formed in a continuous state in the lateral direction.

This fiber cement board raw material 11 is placed on a large number of rollers 21 of the raw material carrying device A. At that time, the stopper 22 is set in the upright state (FIG. 2 shows that state). The upper platen 43 of the punching device B is in the raised position, the piston rod 51 of the separating mechanism E is in the lowered position, and the braking plate 35 of the control means C is in the raised position, so that the stopper 22 is in the lying state. As a result, the fiber cement plate raw material 11 passes through the surface of the flat belt 32 of the control means C, enters the punching device B, and stops at a predetermined position by the stopper provided on the lower surface plate 41 of the punching device B. When the dropping speed is high and the deformation of the fiber cement plate material 11 is expected when the fiber cement board material 11 collides with the stopper, the flat belt 32 and the braking roller 33 of the control means C are operated to operate the fiber cement board material. 11 to control the moving speed.

In this embodiment, the punching upper die 44 of the punching apparatus B has two punching dies 49. As shown in FIG. 12A enters the punching device B, and the remaining eight are located in the conformal passage L on the more upstream side. In this state, the disk 46 is rotated to lower the movable upper platen 43, and the two fiber cement boards 12 and 12 ′ that are divided into small pieces from the fiber cement board base material 11 are indicated by imaginary lines 49 in FIG. Punch into the shape shown. At that time, the braking plate 35 of the control means C is lowered to fix the fiber cement plate raw material 11. As described above, the piercing pieces 49a extending in the radial direction are attached to the periphery of the punching die 49, and a plurality of ears (cutout end pieces) around the remaining portion of the small fiber cement board 12 punched out are simultaneously formed. Is cut into small pieces.

After punching, the disk 46 is operated to raise the movable upper platen 43. As a result, the two punched out small fiber cement boards 12, 12 'are attached to the lower surface plate 4 by their own weight.
It falls along the surface of No. 1, passes through the guide plate 61, falls on the flat belt conveyor 62, and is conveyed to the small fiber cement board collection box 63. At the same time, the surrounding ears divided into a plurality are naturally dropped on the second flat belt conveyor 64 by their own weight and are carried out of the apparatus. Preferably, after being carried out, it is used again as a raw material.

When the punching by the punching die 49 is insufficient, the punched split fiber cement boards 12, 1
It is possible that the separation between the 2'and its surrounding ears is not complete. In particular, in the case of an uncured or primary-cured fiber cement board, the core layer portion of the fiber cement board is in a wet state and sticky, and the punched portion is separated even after punching by the punching die 49. Often becomes insufficient. 1st small fiber cement board 1
If incomplete separation of 2'and the second split fiber cement board 12 or incomplete separation from the respective surrounding ears is caused, the split fiber cement board collection box may be formed. 6
It can be eliminated naturally in the moving process up to 3, or it can be eliminated manually, so that no major obstacle is caused to the continuous punching process. However, the second split fiber cement board 12 and the third split fiber cement board 12A
If the punching between the two is not sufficient, the second split fiber cement board 12 cannot fall naturally due to its own weight, and remains in the same position even if the movable upper surface plate 43 rises. Will end up.

In that case, the next punching step cannot be performed, and the punching process must be temporarily stopped. In particular, as shown in FIG. 5 as a finished product of the split fiber cement board (flat roof material) 12, an uneven notch 12c is formed at the tip of the eaves side, so that a seam with an adjacent flat roof material at the time of construction is formed. When designing so as to be inconspicuous, two small fiber cement boards (standard)
The cutting line length between 12 and 12A becomes long, and imperfect separation tends to occur.

The separating mechanism E is provided in order to completely separate the punched out fiber cement board 12 and the upper fiber cement board body 11 in such a case, and is not shown. When incomplete separation is detected by an appropriate sensor, or each rising cycle of the upper platen 43, as shown in FIG. The portion near the punching line of the body 11 (see FIG. 4) is the conformal passage L
To lift. As a result, the two punched split fiber cement boards 12, 12 'are completely separated from the higher fiber cement board precursor 11 and surely fall downward.

After dropping, the pneumatic cylinder mechanism 36 of the control means C is operated to raise the braking plate 35. Thereby,
The 3rd and 4th small split fiber cement board raw plates 12A of the fiber cement board raw material 11 enter the punching device B again,
Hereinafter, the same operation is repeated. FIG. 2 shows that the 7th and 8th split fiber cement board precursors 12A of the preceding fiber cement board precursor 11 enter the punching device B, and the 9th and 10th.
The second small fiber cement board 12A is shown to be located at the position of the separating mechanism E and the control means C, and 10
The second, that is, the last fiber cement plate original plate 12A is pressed by the braking plate 35 of the control means C, and the movement of the fiber cement plate original body 11 is stopped. The subsequent fiber cement board original material 11 is arranged in the original material conveying device A, and the stopper 22 suppresses the drop. The stoppers 22 are the 9th and 1st of the preceding fiber cement plate precursor 11.
It is in an upright state until the punching of the 0th split fiber cement board original plate 12A is completed, and then it is laid down and the fiber cement board original body 11 of the original body conveying device A is similarly inserted into the punching device B. . Hereinafter, by repeating the same operation, the punching work can be continuously performed.

The above description is a description of a preferred embodiment, and there are many other modified examples of the manufacturing apparatus and manufacturing method of the fiber cement board of the present invention. For example,
The separating device E is arranged such that, in the conformal passage L, one or both ends of the fiber cement plate precursor 11 or the fiber cement plate 12 that has been cut out from the conformer is cut into the conformal passage L surface. As long as it has a function of lifting from above and thereby promoting the separation of the two, there are many modes not limited to the mode shown in FIG. 3.

6 to 10 show an example thereof, and FIG.
In, an eccentric cam 51a having an eccentric rotating shaft 52a is used. Also in this case, the end portion of the fiber cement plate raw material 11 can be lifted by rotating the eccentric cam 51a when necessary. FIG. 7 shows another example,
In this example, a flat plate member 51b pivotally supported at one end is vertically swung by an eccentric cam 51a that eccentrically rotates. In this case, since the flat plate member 51b can come into contact with the fiber cement plate raw material 11 in a wide portion and be lifted, the separation can be performed more reliably.

FIG. 8 shows an example in which air pressure is used, and the nozzle 5
Pressurized air is blown from the tip of 1a to the back surface of the fiber cement board original body 11, and the end portion of the fiber cement board original body 11 is lifted by the fluid pressure. In FIG. 9, negative pressure is used, and the negative pressure source 51d is adsorbed on the front side of the fiber cement board raw material 11, thereby lifting the end portion. FIG. 10 shows still another example, here, the lower surface plate 4 of the punching device B.
A hole 41a is formed at the upstream end position of No. 1 in the punching area by the punching die 49, and a separating mechanism E including a piston rod 55 and a pneumatic cylinder 56 is arranged therein. At its raised position, the piston rod 55 projects above the transport level of the fiber cement plate substrate 11 (here, the punched split fiber cement plate 12) in the substrate passage L (see FIG. 10). Thus, at the lowered position, the withdrawal position is set to retract below the carrying level. In this case, the punched split fiber cement board 1
Since the upper end on the second side is lifted up, there is an advantage that the small fiber cement board 12 drops more quickly and smoothly.

In the above description, the inclination angle α of the original material passage L with the horizontal plane G is set to 45 °, but this inclination angle means that the long fiber cement board original material 11 has its own weight. As long as it is an angle that allows it to spontaneously drop and move to the specified position of the punching device B, it depends on the configuration of the entire device, the frictional force of the raw material passage L, the weight of the fiber cement board raw material 11, the water content, and the like. The optimum angle should be experimentally obtained. Further, the entire apparatus may be tiltably set so that the inclination angle of the conformal material passage L changes.

Further, if the long fiber cement board base material 11 can be moved to the specified position of the punching device B without being particularly deformed by the movement by its own weight, the above-mentioned control means C is not necessarily provided. Absent. Even if it is provided, only the moving speed control mechanism of the fiber cement board original body 11 by the flat belt 32 and the braking roller 33, or the fiber cement board original board 11 by lowering the braking plate 35 and pressing it against the fiber cement board original board 11. Only the braking mechanism that stops the movement of the body 11 may be selectively provided.

Further, when the punching is completely performed only by the operation of the punching device B due to the function of the punching device B or the physical properties of the fiber cement board raw material 11, the separating mechanism E may be omitted. it can.

[0040]

According to the present invention, it is possible to simplify the continuous manufacturing work of a split fiber cement board such as a flat roofing material and greatly save labor, and save the space of the manufacturing apparatus. You can Further, in the case of the one having the separating mechanism, it becomes possible to ensure the separation between the stamped raw material side and the punched small fiber cement board, and the interruption of the manufacturing work due to the inseparability can be surely avoided. .
