Abstract

PURPOSE:To simultaneously and accurately carry in plural steel plates onto the same table by synchronously controlling starting and stopping of line shaft driving system carrying tables continuously arranged on the upstream side and the downstream side of a line. CONSTITUTION:A preceding material 31A is carried at prescribed speed by an upstream side carrying table 10, and tracking is started after the tip reaches a steel plate position detector 30. When the rear end of the preceding material 31A passes through the position detector 30, speed of a downstream side carrying table 20 is reduced, and the table is stopped after the rear end is carried by a prescribed distance. A succeeding material 31B is carried by the upstream side carrying table 10, and when the tip reaches the position detector 30, speed of the upstream side carrying table 10 is reduced. When the tip of the succeeding material 31B is carried by a prescribed distance, the downstream side carrying table 20 is started, and the preceding material 31A is carried at prescribed speed, and the succeeding material 31B is carried at the same speed. In this way, starting and stopping of the respective carrying tables 10 and 20 are continuously controlled by a table control device 40.

A conveying table is usually used as a means for directly moving the steel sheet to each processing step as described above. As the conveying table, a plurality of roller groups are connected by one line shaft. A line shaft drive system is used in which a single drive motor is used. The number of steel plates conveyed by such a line shaft drive type conveyance table is usually one steel plate per table, and it is difficult to convey several steel plates at a time. This is because, when the steel plates straddle the tables, it is necessary to drive the adjacent tables at the same time, and the control of the drive timing of the front and rear tables and the tracking accuracy of the steel plate position for that are quite complicated in terms of control. Because it is required. Therefore, a simple control system is generally used in which a steel plate position sensor is provided between the tables and the steel plate is conveyed / stopped in accordance with the ON / OFF detection signal.

However, in the case of the conventional one-table-one-steel-plate conveying method, the steel sheet is stopped at a predetermined position on the conveying line, and the steel sheet is subjected to, for example, inspection work. When a case occurs, only one steel plate can be implemented per stop unit,
There is a problem that the transport efficiency is reduced.

With respect to the preceding material stop position control mode and the parallel conveyance control mode of the table control device 40, specific control procedures will be described with reference to FIGS. 2 and 3. In each case, the steel plate 31 is conveyed in the arrow F direction.
· Preceding material stop position control mode; First, as shown in FIG. 2 (a), to convey the preceding material 31A by the upstream conveying table 10 at a constant speed v 1 as shown in FIG. 2 (b). Then, at the time t 0 when the tip reaches the steel plate position detector 30 which is the control point, the steel plate position detector 30 is turned on, and the ON signal is input to the table control device 40. Before the tip of the preceding material 31A reaches the steel plate position detector 30, the downstream side transport table 20 is activated at the timing of time t 1 as shown in FIG. 2 (c). After that, the steel plate position detector 30 moves the upstream side transport table 10
The preceding material 31A moving upward is tracked, and an OFF signal is input to the table control device 40 at time t 2 when the rear end of the preceding material 31A passes through the steel plate position detector 30. Therefore, the table control device
40 determines that the preceding material 31A has moved to the downstream side transport table 20 and outputs a deceleration command to decelerate the downstream side transport table 20. At this time t 2 , the downstream side transport table 20 is controlled to the same speed v 1 as the upstream side transport table 10. Then, the advance material 31A is advanced at a predetermined speed v 2 by ΔL between the times t 3 and t 4 , that is, the distance, and then the downstream side transport table 20 is stopped.・ Parallel conveyance control mode: As shown in FIG. 3 (a), the preceding material 31A is stopped on the downstream side conveyance table 20, and the succeeding material 31B is shown by the upstream side conveyance table 10 in FIG. 3 (b). Such a constant speed v
The sheet is conveyed at 3 , and the ON signal of the steel plate position detector 30 is input to the table control device 40 at a time point t 5 when the leading end of the sheet is conveyed to the steel plate position detector 30. Therefore, the table control device 40 is the upstream side transport table.
A deceleration command is output to 10, and the following material 31B is decelerated. on the other hand,
Figure 3 (c), the following material 31B of tip steel position detector 30 passes to a distance ΔL only at t 6 which is advanced and outputs a start instruction of the downstream conveying table 20 by the downstream transport The table 20 is activated, and at time t 7 , the preceding material 31A is moved forward at a predetermined speed v 4 . At this time t 7 , the upstream side transport table 10 is controlled to the same speed v 4 as the downstream side transport table 20. As a result, the preceding material 31A advances together with the following material 31B at the same speed. The table control device 40 moves the upstream side transport table at time t 8 when the rear end of the trailing material 31B moves onto the downstream side transport table 20.
10 is stopped and the leading edge of the preceding material 31A is on the downstream side transport table 20.
The downstream side transport table 20 is stopped at the time point t 9 when it reaches the end of the table. As a result, the leading material 31A and the trailing material 31B are simultaneously carried onto the downstream side transport table 20.

By such a procedure, the table control device 40 continuously controls the start and stop of the upstream side transport table 10 and the downstream side transport table 20,
It is possible to efficiently carry in a plurality of steel plates on the same table. If such a control method is applied to the receiving side table when transferring a thick plate material to another line using a transfer car, for example, it is possible to convey a plurality of thick plate materials at the same time by the transfer car. Therefore, the transport efficiency can be improved.
