Of course, other resection methods can also be used. Cutting the joint 1 1 requires at least two cutting operations according to the plate cutter 2 4. If the joint cannot be removed well with the two cutting operations, repeat the cutting operation as shown in Figure 9 Until the joint 11 can be removed. Since the leading end of the leading metal sheet 10 after cutting the joint has been bitten into the finishing rolling mill group 26, the rolling is continued. On the other hand, after cutting the joints, the metal sheets 12 and 12 are rolled to change the rolling schedule of the first piece of endless rolling, or to change the rolling schedule of a batch of rolled materials.

Printed by the Economic Village Intellectual Property Bureau employee consumer cooperative 452508 A7 B7 V. Description of the invention (15) Specifically, the predetermined thickness of the metal sheet 12 after cutting the joint is a sufficient thickness that can still be subjected to batch rolling. At that time, it is still rolled to a predetermined thickness. On the other hand, after the joining is stopped, or after the joint is cut, the scheduled rolling schedule of the metal sheet 12 is performed. If the finishing thickness is less than 1.2 mm, for example, endless rolling can be applied, but batch rolling cannot be performed. When the material is thin, it cannot be rolled in batches according to the predetermined rolling schedule. This is because the rolling of the first metal sheet is ended, and then the finishing rolling mill is installed after the subsequent rolling of the metal sheet. It usually takes tens of seconds, or even tens of seconds. Therefore, during this period, the temperature of the downstream metal sheet will drop and become hard, making it impossible to apply rolling at a predetermined thickness. As the material becomes thinner, if it is rolled after the 10th (assuming a thickness change of 0.7 mm from 2.3 mm to 1.6 mm can be responded to), or as a batch rolled material of 1.2 mm without changing the thickness Either of the rolls is applied. Similarly, for the third sheet and later, the finishing thickness is predetermined. If it can be achieved within the range of the ability to change the thickness control during the continuous finishing hot rolling, then rolling is applied after joining. If it is impossible, rolling is performed as a batch rolling material. '

In addition, the ability to change the thickness control during walking is based on the speed of the speed control system for the rate of change of the thickness X (rolling speed (volume speed)) or the response speed of the tension control system (tension. , Or the opposite decrease in tension can prevent the board from repeating to what extent), or shape control ability.

Description of the invention (16) (谞 read the first Please fill in this page again for attention) After the termination of the joining, there will be various equipment (joining device 40 or subsequent processing device 50) for the joining, which will act as the first piece of endless rolling, or a batch of rolled materials. As shown in the figure, there is a danger that the front 1 2 A snakes on any of the stands of the finishing and rolling mill group at the front end, so that it may protrude from the side guide 75. Also, in FIG. 10, the symbol 16 is The above-mentioned bundling machine used in Fig. 7. In this case, 'the following metal sheet 12 is changed to the first endless rolling, or the rolling schedule of the batch rolling material is applied to the rolling. Physically, rolling is performed under the finishing roll for the entire length or at least the front end to have a thickness of, for example, a finishing thickness of 1.2 mm or more. In addition, the subsequent continuous operation of the second and subsequent pieces of the above-mentioned trailing metal sheet 12 and 2 is performed. The metal sheet is rolled by the rolling schedule of the first endless rolling, or by the second endless rolling The rolling schedule is based on the rolling schedule of batches of rolled materials. It is printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, that is, after the joining is suspended, the metal sheet 12 will be rolled into endless rolling. At the time of the first sheet, there may be a case where the subsequent metal sheet is continuously rolled after the second sheet of the following metal sheet 12 in accordance with a predetermined rolling schedule or not in accordance with the predetermined rolling schedule. For example, the joining will be suspended When the following metal sheet 12 becomes the first sheet for endless rolling, the finishing thickness is reset to 1.2 mm or more for the reasons described above. Since it is a stoppage of joining, the through sheet of the following metal sheet 12 is passed through. The deviation of the time until the preparation is completed. The specific number of thicknesses that can be rolled is set as the number of millimeters. As an example, it is assumed to be reset to 2.3 mm. If the second subsequent piece of metal is continuous to this When the pre-determined thickness is 2.0 mm, 'Since the first -19- this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 452508 A7 _ B7 _ V. Invention Note (17) The thickness change from sheet to second sheet is only 0.3mm. So there is no problem. However, if the predetermined thickness of the second sheet is 1.2mm, the thickness change from the first sheet to the second sheet There is 1.1 mm, so as shown in Figure 11, the thickness change control ability of changing the thickness between the running of the finishing roll mill is impossible. It is impossible to change the thickness. Instead, the predetermined thickness of the second sheet can be changed. When the thickness is 1.6 mm, the front end of the joint can be rolled up. After this operation is completed, the front end of the metal sheet after passing the interruption is passed through the equipment. The 10 and the trailing metal sheet 1 2 must be separated and win-rolled. Therefore, the trailing sheet 12 1 side is stopped or decelerated. The leading metal sheet 10 side is in all cases, because the front end is already rolled by the finishing rolling mill group 26, so it is still rolled according to the finishing rolling mill group 26. If it is a thin material, there is a risk of stretching when the end of the finishing roll is detached. Therefore, it is also possible to increase the thickness of the end. Incidentally, in the latter embodiment, the bonding device 40 side and the rear metal sheet 1 The two-side synchronization speed becomes once stopped. At this time, even if it is considered that once the trailing metal sheet 12 is stopped, the transport of the trailing metal sheet 12 is resumed in a state where the through-board condition manufacturing operation of the bonding device 40 and the subsequent processing device 50 described later is completed, Until the time required for finishing rolling, it is also assumed that there is no case where the trailing metal sheet 12 becomes too hard due to temperature drop and cannot be rolled. The leading metal sheet 10 is moved to the downstream side than the lifting platform belt, and the trailing is performed. The metal plate 12 or subsequent metal plate through-plate conditions are created.

For this, if the positional relationship is not appropriate, for example, as shown in Figure 14, if there is a lifting roller 6 6 B that has not risen to the upper and lower limit, the lifting roller 6 6 A at the rising limit and the roller 4 6 of the joining device When the interval Q passes through the leading end of the trailing metal sheet 1 2 A in a large state, the gap falls and infiltrates the leading end of the trailing metal sheet 1 2 A in this gap, and it becomes impossible to pass the above. Therefore, it becomes It is ideal to stop the joining device 40 in a relationship between the joining device 40 and the lifting roller 6 6 A as shown in FIG. 13.

Here, the follow-up processing device proposed by Japanese Patent Laid-Open No. 9-1 2 9 5 2 8 is taken as an example to explain the production of the pass-through conditions of the subsequent processing device 50 after stopping the joining of the metal sheet 12 or the subsequent metal sheet. method. That is, in a state where the joining is normally performed, as shown in FIG. 15, 1 the pressing device 5 1 and the pressing device 5 3 are located at the cutting position, and the opening / closing scale 5 5 is opened. The rotation of the rotating blade 5 2 and 5 4 rotates at a high speed (for example, a peripheral speed of 80 to 10 Om / sec) in a reverse direction opposite to the direction in which the metal sheet is conveyed. When the joining is suspended, the running system of the joining device 40 is stopped once, and the conveying system of the subsequent sheet metal 12 is stopped or decelerated. At this time, one of the post-processing devices 50, as shown in Fig. 16, opens the pressing device 51 and the pressing devices 53, 54 without closing the opening-and-closing scale 55. The rotary blades 5 2 and 5 4 rotate at the same speed as the metal sheet conveying speed in the same direction as the metal sheet conveying direction.

Description of the Invention (21) The embodiment described above is an example in which the present invention is applied to a hot-rolling facility having a joining device that performs heat-welding by an inductor, but the hot-rolling facility to which the present invention is applicable is not limited to this facility. After the opposite end 10B and the front end 12A, hot rolling equipment having a joining device that performs joining by, for example, laser welding can also be applied. When the laser welding welding device is used, heating is performed on the joint portion of the metal sheet by the laser after the ends 10 B and the front end 1 2 A are opposed to each other. The determination of whether or not to terminate the joining is carried out before the heating by laser is started. In the above embodiment, the above-mentioned embodiment is a hot rolling with a subsequent processing device 50 for removing the burr on the joining part on the output side of the joining device. The equipment is applicable to the present invention, but the present invention is not limited to the equipment, and of course, it is also applicable to the case of the subsequent processing of pressing the burrs into the metal sheet or the hot rolling equipment without the subsequent processing device. The next problem is that from the time when the incomplete joint is generated to the time when the part is cut, even if the incomplete joint with insufficient strength is broken, it can be carried without trouble such as overhang. For this reason, in the present invention, the joint between the leading metal sheet and the trailing metal sheet that the speed conveying is not completely completed in synchronization with the walking of the bonding device, the bonding device stops after traveling to the lowest downstream of the walking belt, and the leading metal sheet and the The trailing metal sheet is not stopped at this time, and the front end is still being transported at the conveying speed of the leading metal sheet before being rolled in the finishing roll mill.

Description of the invention (22), when moving the joint device 40, 'the lifting case roller 6 6 is lowered to push the guide 4 5 A on the platform of the entry side and the exit side of the joint device 40, In the state of 4 5 B, 'the person moving one side in turn while moving downwards] will be explained as an example. In this way, when the incomplete engagement occurs during the walking of the engaging device 40, the normal operation when it is engaged normally (after the engaging device 40 is engaged, after opening the clamp, once it stops, it returns for the next engagement. To the starting position in FIG. 8), once the walking of the joining device 40 is stopped, the joining portion that is not completely joined is conveyed to the downstream side of the joining device 40. As a result, the joint portion 11 starts to move from the joint device 40 directly downstream, just when the joint portion 11 is broken. After the fracture, the leading edge of the metal sheet 1 2 A warps downward due to creep, as shown in Fig. 19, it will fall into the gap Q between the rollers. The reason for these gaps is that the relative relationship between the stopping position of the joint device 40 and the lifting position of the lifting roller is inappropriate. That is, as shown in FIG. 13, if the roller 46 on the bonding device 40 and the upstream Q of the bonding device 40 and the span Q of the downstream lifting roller 66 in the downstream stop the bonding device 40 at an appropriate position, The above-mentioned span Q is set to a pitch P of approximately the lifting rollers 66. However, if this positional relationship is not appropriate, as shown in Fig. 19, if there is a lifting roller 6 6 A that has not risen to the rising limit. It will produce a longer span Q than the pitch P of the lifting roller. The span Q will stop the joining device to become 0.5P'Q and the range of 1.5P is reasonable.

Description of the invention (23) In theory, at each pitch of the component lifting rollers, there is a stopping position of the engaging device of the platform gap when the platform pushing guide is not raised. Therefore, the walking trolley 4 stops at this position, and the lifting platform can be implemented. • Pushing the guides 45A and 45B. However, for the sake of simplicity, as shown in Fig. 8, it is also possible to determine several locations. However, in this case, during this operation, the front end 1 2 A of the trailing metal sheet may fall into the platform gap. This is because during the ascending action of the platform pushing guide, the first metal sheet 10 and the second metal sheet 12 continue to be transported.

Stop the movement of the walking trolley 4 2 at the stop position of the joint device where the platform gap does not occur, so that the movement of the ascending platform pushing the guides 4 5A and 4 5 B is sufficiently fast, before the front end of the backward metal sheet 1_ 2 A comes to this position. When the platform gap can be plugged, as shown in Fig. 20, viewed from the position of the engaging device at the time of incomplete engagement, the engaging device 40 stops at the nearest downstream side exceeding the platform clearance of 1. 5 P without occurring It is also possible to raise the platform at least on the downstream side (for the joint device 40, it is the exit side). 4 5 B and 1 are at the front end of the trailing metal sheet 1 2 A and cannot reach the rising platform before reaching the platform clearance part. When the action of the pushing guide 4 5 B cannot block the platform gap, the joint device 40 is walking in synchronization with the incomplete joint portion, and it stops after walking to the walking belt. At this time, it is pushed on the platform of the joint device 40. As shown in FIG. 21, the pressure guide member pushes the guide member 4 5 B at least on the platform on the downstream side (out side for the bonding device 40), and moves the roller 46 on the bonding device 40 and the bonding device.

The leading metal sheet 10 and the trailing metal sheet 12 are not stopped at this time, and the leading end is still being transported at the leading metal sheet rolling speed which has been rolled in the finishing rolling mill group 26. Whether the action of the ascending platform pressing guide 4 5 B can catch up with the front end 1 2 A of the leading metal sheet before reaching the platform gap, and the equipment capabilities of the actuator that presses the guiding 4 5 B by the ascending platform, and It can be determined by the metal sheet 1 2 conveying speed. When the above-mentioned post-processing device 50 is a burr removing device for removing burrs occurring at the joint portion, as shown in FIG. 15, it is intended to join the leading metal sheet and the trailing metal sheet that are not completely joined as shown in FIG. 15. When the burr of the portion is removed, a tensile force is exerted in the direction of opening the joint portion from the rotating blade 54 toward the metal sheet joint portion 1 1, so the joint portion 11 may be broken. Therefore, when it is known that the joint is incomplete, it is desirable to stop the removal of the defective joint. Specifically, as shown in FIG. 2, the rotating blades 5 2, 5 4 are returned to the cutting waiting position, or if possible, as shown in FIG. 16, the rotating blades 52, 54 are fully opened, and the opening and closing type are opened.

In these cases, by pressing the button for cutting the joint (step button 12 0), the treatment for cutting the joint is performed (step 15 0). After that, for the subsequent metal sheet that is continuous with the subsequent metal sheet, the implementation is performed. Bonding can be performed without rolling, or the composition can be changed by batch rolling and rolling. It is also possible to change the composition batch rolling and roll, and the joining device 40 or the post-processing device 50 must be able to pass through the front end of the subsequent sheet metal.

(Embodiment 1) • Four-joint endless rolling is now being carried out (the first sheet is a low carbon steel 1.2 X 1 0 0 n ^ m, and the second sheet is a low carbon steel 1.0 x 1000mm. Three sheets are made of low carbon steel (1.0x1000mm), and the fourth sheet is made of low carbon steel (1.2x100mm). It is assumed that the joining of the end of the second sheet to the front end of the third sheet is suspended. When the joining becomes suspended, the running of the joining device 40 and the conveyance of the following sheet metal 12 are at a synchronized speed-once stopped. The stop position of the leading end of the backward metal piece (third piece) at the time of stopping the joining is 1 2 A. As shown in FIG. 8, the starting position of the running belt at the joining device 40 is taken as Om (reference), which is 1 . 5 m location. Once the stop is completed, the end of the leading metal piece 10 B moves to the lifting platform belt (in Figure 8, the so-called lifting platform located at the end of the stroke when the joint device is walking is the downstream limit of the lifting platform belt. ) Further downstream, as shown in Figure 1 3.
