Description

Description: TECHNICAL FIELD The present invention relates to a method for cutting a molding plate such as a building member, and a cutting apparatus therefor, and particularly, for molding and cutting a siding board, which is an outer wall material, from a flat plate. The present invention relates to a cutting method and a cutting device for obtaining a molded plate such as a siding board.

(Prior Art) In the conventional cutting of a molded plate, a continuous flat plate was continuously molded by a pressing machine or the like, and then cut into an arbitrary length. In addition, as a method for manufacturing fireproof and fireproof panels,
As disclosed in Japanese Patent Laid-Open No. 30175, "Metal-formed hoop material is a horizontal strip formed by bending a long strip-shaped metal plate into a receiving shape and sandwiching a recessed portion so that both side edges project inward and outward. Is moved in the longitudinal direction, and a liquid adhesive is sprayed on the upper surface of the metal molded hoop material, and an appropriate amount of fireproof and fireproof heat insulating material is first dropped and supplied into the concave portion of the metal molding hoop material. With a pushing member connected to a pushing mechanism provided near the recessed portion, it is sufficiently pushed into the inner portion of the recessed portion, and then a fireproof and fireproof insulating material is replenished and dropped while maintaining a considerable thickness over the entire upper surface of the metal forming hoop material. Let
After having a predetermined thickness with a thickness regulating member, the
The back paper is supplied on the surface of the fireproof heat insulating member, and the one that can be hidden is sandwiched by a moving thermocompression molding die, and the fireproof heat insulating material is molded to a predetermined thickness and integrally bonded with the metal molding hoop material, It is a method of manufacturing a fireproof panel that is resistant to fire, characterized by cutting to the required length. This is a very long piece that is continuously molded, filled with a fireproof heat insulating material, and finally any required A method and an apparatus for cutting what is molded and filled into a length.

In addition, a flat plate is cut into an arbitrary length and then formed into a required shape.

(Problems of the prior art) In the above-mentioned conventional method and apparatus for cutting a molding plate, in the case of a method and an apparatus for cutting after molding into an arbitrary shape, the cutting apparatus is complicated and has high performance. Will be needed, especially
For example, when a deck plate or the like having a special T-shape is cut, the deck plate is deformed and the commercial value thereof is significantly deteriorated.

When changing the plate thickness during the processing of a continuous flat plate, plate loss occurs. Further, in the case of continuous molding, the processing members of the molding machine are complicated and the price of the molding machine becomes expensive.

Further, in the method and apparatus (which corresponds to the case of non-continuous one) in which a flat plate is cut to an arbitrary length and then molded, it takes time to adjust the rolls by changing the plate thickness.

Roll slip causes troubles in the molding machine (collisions, overlapping plates, etc.).

The shape of the top and the end cannot be done as desired, and in order to solve this, many rolls must be used, and the device itself becomes bulky.

There are various problems.

(Technical problem to be solved by the present invention) In view of the above-mentioned problems of the prior art, the present invention does not require a complicated and high-performance cutting device, and moreover, does not deform during cutting. It does not cause, even if it is short in length, it does not cause collision, plate overlapping, and it does not cause plate loss when switching plate thickness, and furthermore, it is a method of cutting a molded plate that does not take time for roll adjustment, It is a technical subject to obtain the cutting device.

(Technical Means for Solving Problems) The present invention provides a continuous long flat plate fed from an uncoiler through a leveler in order to obtain a molded plate having a predetermined length in order to solve the above technical problem. In the flat plate state, when it is bent and molded, the flat plate that remains unfolded is left uncut, and when molded, the bent part is cut at a position corresponding to the predetermined length. Notch cutting step, step of forming continuous continuous flat plate with this cutting notch into an arbitrary shape with a molding machine, and then running to cut the flat plate part that was not cut in the previous notch cutting step A method for cutting a molded plate, which comprises a cutting step. Further, in an apparatus for producing a molded plate of a predetermined length, a transfer device for transferring a continuous long flat plate, and when the continuous long flat plate is bent and formed in the next step, a portion that cannot be bent as a flat plate is cut. A cutout cutting machine that cuts a portion that can be bent at a position corresponding to the predetermined length when left unmolded and a molding machine that bends and shapes the cutout continuous continuous flat plate into an arbitrary shape And a cutting machine for cutting a flat plate end that has not been cut by the notch cutting machine, as a means.

Further, the above technical means has the following effects. That is, after the molding, since the portion to be the bent portion is cut in advance in the flat plate state, it is possible to manufacture the molded plate by cutting only the remaining flat plate portion after molding the bent portion and the like.

(Effects peculiar to the invention) With the above technical means of the present invention, the following peculiar effects are produced, that is, since molding is performed in the state of a continuous flat plate, molding of each simple substance, particularly of short dimension (short length) The plate can be obtained very easily.

Since molding is performed continuously, the molding dimensions of the top and end during molding are stable.

When molding flat plates after cutting, work was done with a gap between the front plate and the rear plate to prevent slipping and other obstacles, but since it is a continuous flat plate, there is a gap. Since there is no need to hold it, the loss of molding work is significantly reduced.

Since the cutting before molding is a flat plate, a simple cutting device may be used, and further, the part to be cut after molding only needs to cut the flat plate part, so cutting work can be performed with an extremely simple cutting device. it can.

As described above, it has many effects such as increased productivity and prevention of troubles.

(Example) Next, the Example of the technical means of this invention is described based on drawing.

FIG. 1 is an explanatory view of an apparatus for carrying out the present invention, and FIG.
The figure is cut by the notch cutting machine (3) shown in FIG.
Before molding, an enlarged plan view showing a part corresponding to the part that is bent at the time of molding is cut out in a continuous flat plate state, and FIG. 3 is a cutout cut as shown in FIG. FIG. 4 is a perspective view of one embodiment showing the molded part, and FIG. 4 is a part to be cut by a cross-cutting machine which is cut in the next step after being molded in FIG. 3 (in other words, a flat plate that is not bent and remains. FIG. 5 is a perspective view showing a deck plate having a T-shaped cross section, which can be very well cut particularly when cut by the technique of the present invention.

The method for cutting a molded plate and the cutting device thereof according to the present invention are configured such that a continuous flat plate is continuously fed from the uncoiler (1), and the leveler (2) makes it easy to cut by the notch cutting machine (3). Transfer to machine (3). The notch cutting machine (3) may be any notch cutting machine (3) as long as the notch cutting machine (3) cuts into a length of an arbitrary dimension to be formed into a final product, but this is a complete cutting machine. It must be able to be in a state where it is not partially cut, instead of being cut into pieces.

In other words, when cutting to an arbitrary length before bending and molding, instead of completely cutting the cut, make it possible to make a cut part and a non-cut part like the so-called perforation. Do it after calculating in advance. In this cutting, when the product is finally made, the part corresponding to the bent part is cut, and all or part of the flat part is left uncut, and a cut is made by a press cutting machine or the like. Steps and zones are added in several steps.

In addition, when the flat plate end is cut into a notch with an arbitrary width,
It is easy to carry out the next process work such as bending press work. For this reason, it may be necessary to cut out together with other cutting parts in advance.

This is because the cut portion (7), which is finally molded and becomes the bent portion (9), is cut in the flat plate state (second
(See the figure) Next, the molding machine (4) bends and molds it into the desired shape. This molding machine (4) drives the molding rolls in multiple divisions so that the peripheral speed can be changed in multiple stages (depending on the complexity of the machining shape). Depending on the design, it is possible to select the number of divisions accordingly, and each peripheral speed can be changed. Needless to say, this is better if the molding is made efficient by, for example, the inlet side being slow and the outlet side being fast.

After bending and molding with this molding machine, the part that remains without being cut by the running cutting device (5) {This is the part that cannot be bent as a flat plate when being bent and remains without being cut. Therefore, the flat part (8) is cut. } (6) in FIG. 1 is an accumulator, which is a staying part required for continuous operation by adjusting the difference in working time between the notch cutting step and the molding step.

In addition, when setting the tip of the flat plate to the cutting machine (5),
Since the tip of the flat plate may be deformed in some cases, in such a case, it may be possible to provide a pressing roll or the like immediately before the cutting machine (5) so that the plate can be reliably set. Further, it is needless to say that various devices, for example, photoelectric switches and the like are provided as necessary for the sake of safety.
