  By the way, using such a roll forming machine, for example, when forming an extremely short length (having a length of less than 1 m), it is difficult to transfer the plate material from the roll pair to the roll pair. Therefore, a plate material having a long length is formed in advance, and then a desired length is obtained through a cutting operation using a high speed cutting machine or a plasma cutting machine with a polishing disk. However, in such cutting work, a positioning step for determining the cut portion is indispensable, there is a problem that the cutting itself takes time, and since the occurrence of burrs is unavoidable, its processing is also necessary and efficient. It cannot be said that it can be manufactured. Moreover, when the plate material involved in molding has a complicated cross-sectional shape, there is a concern that the cross-sectional shape may be deformed during cutting, so there is a possibility that the molding of the plate material using a roll molding machine may be restricted. There is still room for improvement.

  An object of the present invention is to propose a roll-formed plate-like body that can be efficiently manufactured without causing the above-mentioned problems, a method for manufacturing the same, and a series of manufacturing equipment therefor.

  The present invention is equivalent to the caliber formed on the roll surface of the roll pair by passing the plate material discharged from the steel plate coil once or a plurality of times between the rolls of the roll pair sandwiching the plate material. A roll-molded plate-shaped body provided with a cross-sectional shape consisting of a shape, the plate-shaped body being formed from one end in the width direction toward the other end, and having a fixed-scale plate-like shape by bending from that portion A roll-molded plate-shaped body having at least one breaking line that can be separated from the body.

  The planned breaking line has a thickness equivalent to that of the plate material, and includes at least one narrow piece that can be broken by bending of the portion and at least one cutout formed adjacent to the narrow piece. In addition, at least one narrow piece that has the same thickness as the plate material and can be broken by bending the part, and is formed adjacent to the narrow piece. It is preferable that it is composed of at least one through hole penetrating in the thickness direction.

  Further, the present invention relates to a method for producing a roll-formed plate-like body, in which a planned breaking line is formed on a plate material discharged from a steel plate coil, and then a roll forming machine equipped with a pair of rolls sandwiching the plate material is used. A method for producing a roll-molded plate-shaped body, characterized in that a cross-sectional shape having a shape similar to that of a caliber formed on the roll surface of the roll is imparted by passing through the roll once or plural times.

  Further, the present invention comprises at least one pair of rolls sandwiching the plate material discharged from the steel plate coil, and by passing the rolls of the roll pair one or more times, the roll surface of the roll is A roll forming machine that imparts a cross-sectional shape having the same shape as the formed caliber, and is installed on the entrance side of the roll forming machine, and before the plate material discharged from the steel plate coil is passed through the roll forming machine.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is an external view showing an embodiment of a roll-molded plate-like body according to the present invention as an example of a fitting type roofing material (standing flat roofing material) having an upper goby and a lower goby at ends in the width direction. 2A is a perspective view, FIG. 2A is a plan view of FIG. 1, and FIG. 2B is a front view of FIG. 1. The roll-formed plate is specifically a metal such as a zinc-plated steel plate, an aluminum-zinc alloy-plated steel plate, a stainless steel plate, a copper plate, an aluminum plate having a thickness of about 0.3 to 1.2 mm, or a coated or coated steel plate thereof. What is made up of manufacturing members is applied.

  The fitting type roofing materials shown in FIGS. 1 and 2 are provided with a plurality of sheets having the same cross-sectional shape but different lengths and plane shapes. By linking them to each other, it is possible to join the roof materials from the eaves of the building structure to the ridge, while fitting the upper goby and the lower goby to the lower goby and the upper goby of the adjacent roof materials. By doing so, it is possible to join the roofing materials along the eaves of the building structure, and the roofing is performed by repeating these joining operations.

  In the drawings, reference numeral 1 is a flat roof material main body, 2 is a lower hook provided at one end of the roof material main body 1 in the width direction, and 3 is the other width direction of the roof material main body 1. It is an upper goby provided at the end. In addition, 4 is a planned breaking line formed from one end in the width direction of the roofing material main body 1 toward the other end. The planned breaking line 4 has a thickness equal to that of the plate material before molding and can be broken by bending the portion, and a through hole penetrating in the thickness direction of the roof material main body 1. 4b. The size of the rupturable narrow piece 4a is appropriately determined according to the conditions such as the material and thickness of the target roofing material. For example, in the case of a galvanized steel sheet having a thickness of about 0.3 to 0.5 mm, it is about 1 to 20 mm. The planned breaking line 4 is shown as an example in which the narrow piece 4a and the through hole 4b are combined, but the narrow piece 4a and the notch 4c (see FIGS. 8 and 10) or the narrow piece. 4a, through-hole 4b, and notch 4c can be combined appropriately. The opening gap t of the through opening 4b is also appropriately determined according to the material and thickness of the target roofing material. For example, in the case of a galvanized steel sheet having a thickness of about 0.3 to 0.5 mm, it is about 1 to 20 mm.

  The above-mentioned fitting type roofing material and the like, provided with a plurality of roll pairs, for example, in the case of using a multi-stage roll molding machine, if the length is extremely short, the plate material, Since it becomes difficult to transfer from roll pair to roll pair, usually, one with a long length is molded in advance, and then a desired length is obtained after cutting work using a high speed cutting machine with a polishing disk or a plasma cutting machine. As described above, it is difficult to perform efficient manufacturing with such a molding method.

  The roll-molded plate-shaped body of the present invention has a length as shown in FIG. 3 which is obtained by bending the plate material itself after the roll-molded plate-shaped body is molded with the planned breaking line 4 as a starting point and cutting the narrow piece 4a. It is to be cut into short fixed-length plate-shaped bodies, and the separated plate-shaped bodies do not require complicated cutting work as in the past and can be used as a product as they are.

  FIG. 4 is a diagram schematically showing an example of a manufacturing equipment row suitable for manufacturing the roll-molded plate-shaped body according to the present invention.

  In FIG. 4, reference numeral 5 is a steel plate coil, 6 is a cutting device for cutting the steel plate coil 5 into a predetermined length, and 7 is a roll forming machine.

  The roll forming machine 7 is shown here as an example in which seven roll pairs 7a to 7g are arranged in tandem. A caliber is formed on the roll surface of each of the roll pairs 7a to 7g. The caliber progresses in a stepwise manner. A cross-sectional shape having the same shape as that of is given.

  Further, reference numeral 8 is a puncher which is arranged on the entrance side of the roll forming machine 7 and for forming the planned breaking line 4 on the plate 5 '. As the puncher 8, for example, a press type equipped with a punching die can be used, but the type thereof is not particularly limited as long as the planned breaking line 4 can be efficiently formed.

  In order to manufacture a roll-formed plate-like body as shown in FIG. 1 above using such a production equipment row, first, for the plate material 5 ′ delivered from the steel plate coil 5, the puncher 8 shown in FIG. A planned breaking line 4 is formed as shown. Then, subsequently, the plate material 5 ′ may be passed through the roll forming machine 7 to be formed.

  The planned rupture line 4 is shown here as an example in which the inclined angle is added so that the end shape after the roll-formed plate-like body is cut off becomes a tip shape, but the planned rupture line 4 is shown in FIG. It is also possible to have a line type and shape as shown in FIG. 11, and regarding the arranging form of the narrow width piece 4a and the through hole 4b of the planned breaking line 4, the plane shape, etc., It is variously modified according to the purpose of use, and is not limited to the illustrated one. The reference numeral 4c in FIGS. 9 and 11 indicates a notch.

  Needless to say, the planned breaking line 4 is arbitrarily formed according to the desired length of the roll-molded plate-shaped body.

  The roll-formed plate according to the present invention can be efficiently manufactured and has very high utility even if it has a complicated cross-sectional shape or a short object is formed.

  According to the present invention, it is possible to provide a roll-formed plate-like body that can be efficiently manufactured, a manufacturing method thereof, and a manufacturing equipment row.
