摘要： PURPOSE:To prevent speed reduction of the pre-processing section and prevent stopping of the intermediate processing section as long as possible by providing a speed criteria switching means where three speed criteria are added to the respective corresponding sections when the post-processing section is operated at a reduced speed or stopped. CONSTITUTION:A speed criteria circuits 41,43 generate the speed criteria for the pre-processing section and the post-processing section respectively. A speed criteria circuit 73 calculates and outputs the speed criteria of the intermediate processing section where two loopers reach the longer end at the same time on the basis of these speed criteria. A speed criteria switching means achieves ON/OFF operation of contacts 44, 46, 48 and adds the speed criteria of the speed criteria circuit 41 to the intermediate processing and the post-processing sections respectively during the normal operation, adds the speed criteria of the speed criteria circuit 41 to the pre-processing section when the post- processing section is operated at a reduced speed or stopped, adds the output of the speed criteria generating means 73 to the intermediate processing section, and adds the speed criteria of the speed criteria circuit 43 to the post-processing section respectively.

摘要： PURPOSE:To detect the overlap part of strip like materials. CONSTITUTION:At the time of the detection of the position where the rear end part of a preceding strip 1 and the leading end part of a succeeding strip 2 are mutually overlapped and connected in a process line continuously treating the strip like materials, the distances up to the upper surface of the strips are measured by first and second distance meters 4, 5 attached in the advance direction of the strips so as to provide a predetermined interval from the upper part of the line. The difference in level of the strips is judged by operation using two obtained measured values to determine the position of the overlap part of the strips to accurately and stably detect the overlap part of the strips.

The position of the adhesive tape 7b on the leader tape 7 is detected with a detector 15 and stored. A press roll 8 is pressed against the coil 3a of spacer paper and the second half part of the adhesive tape 7b is stuck to the tip of spacer paper by operating a cylinder 9. The tip of spacer paper 21 is stuck to the tip of the strip 1 with the press roll 8 by operating the cylinder 9 and the coiling of the strip 1 is started after the press roll 8 is retreated. The charging of spacer paper can be automated and it can contribute to laborsaving and improvement of production efficiency.

摘要： PURPOSE:To electrically compensate the braking torque, and to prevent generation of breadth shortage in the strip and of the necking, by computing the inertial energy from the rotational speed of the mandrel, and by correcting the previously set pattern. CONSTITUTION:The detected values of the speed detectors 5, 10, are input to the relay amplifier 111, and the line's synchronous speed vF is compared with the mandrel speed vM; then, if the relation vM>betavF (in which, beta is a value patterned according to the rolling schedule, and means the catch-up condition of the speed, and has a value of 1 or larger) is satisfied, the relay 109 is excited. The compensating circuit works from the beginning of winding of the strip 2 around the mandrel, however, the mandrel speed slows down at this stage, the relay 104 is put ON, the relay 107 is put OFF, and the integrator 105 works to produce the time signal. Hereupon, the relay 109 is being put ON according to the satisfaction of the relation vM>betavF, and the compensation at winding the strip is carried out by the output of the multiplier 108.

摘要： PURPOSE:To deflect the opening of a gate between passing of a preceding plate and after passing thereof by constructing a gate for switching a running path for an end plate cut from a metal band on a process line and guiding the same in such a manner as to be opened and closed by a driving means with two-stage stroke. CONSTITUTION:On monitoring the leading and trailing ends of a strip 1 and an end plate 3 passed on a process line, the optimum gate opening angle is commanded to a gate opening and closing device. At this time, the gate opening and closing device is adapted to adjust the gate opening in two stages according to the line speed and the conveyer speed. As the gates 4, 5 are opened and closed by a set of major and minor air cylinders 4a, 5a, delay and variation of operation is hardly caused even for a high speed line, and further as the gate opening and closing angle is adjusted in two stages according to the passing timing of the strip 1 and the end plate 3, no reject error occurs.

摘要： PURPOSE:To prevent scratch from producing on a strip by making shearing blades installed on two knife drums opposed vertically not to contact with the strip. CONSTITUTION:Eccentric gears 13, 14 and 15, 16 are installed in upper and lower knife drums 1 and 2, respectively, the gears are rotated by eccentric gear driving pinions 17, 18 and 19, 20 installed on eccentric gear driving motors M1, M2 and M3, M4, respectively, to revolve the both knife drums 1 and 2 about the eccentric gears 13, 14 and 15, 16, respectively, and to near and depart them to and from a strip 5, respectively. Pinch rolls 25, 26 and 27, 28 are provided at the inlet and outlet of the knife drums 1 and 2, respectively. When the strip is not cut, a shearing blade is not made in contact with the strip nor any scratch is produced since the both knife drums are separated from the strip. Also fluctuation of the strip under cutting is suppressed by the pinch rolls to maintain securer cutting.

摘要： PURPOSE:To improve production efficiency and product quality by performing the motor control of a skin pass mill by the tension of a metallic band plate when a roll is screwed down and the rotational speed when the roll is released. CONSTITUTION:The motor control of the skin pass mill 3 of a process line for metallic band plate 1 should be performed by either of the tension value of metallic band plate 1 or the value of rotational speed of skin pass mill roll 3. And, the state of rolling-down or release of the skin pass mill roll 3 is judged and the motor for the skin pass mill roll 3 is controlled so that the tension of the metallic band plate becomes a specified value in the former case and so that the rotational speed of the skin pass mill roll 3 becomes a specified value in the latter case. In this way, the stoppage of the process line for metallic band plate and the deterioration of thickness accuracy are prevented and production efficiency and product quality can be improved.

摘要： PURPOSE:To perfectly automate coiling work by pressing and sticking a double coated adhesive tape on a leader tape to the tip part of spacer paper and winding an spacer paper by pressing the adhesive tape on a winding shaft for spacer paper. CONSTITUTION:The strip 2 of a coil 1 is uncoiled with pinch rolls 16. At this time, the spacer paper 3 is separated from the strip 2 and hung down. When the tip of the spacer paper 3 is detected with a detector 7, a pay-off reel 15 is reversed and the tip of the spacer paper 3 is made so as to come to on the extension line of a cylinder 10 for a press roll 9. The tip position of the adhesive tape 4 which is stuck on the leader tape 5 is detected with a detector 8 and stored. The cylinders 10, 12 are operated after positioning and the press rolls 9, 11 are pressed against the pay-off reel 15 and a winder 6 for spacer paper and the second half part of the adhesive tape 4 is stuck on the spacer paper 3. The first half part of the adhesive tape 4 is stuck to the winder 6 by revolving the pay-off reel 15 forward and the press rolls 9, 11 are separated and the spacer paper 3 is wound with the winder 6.

摘要： PURPOSE:To enhance the reliability of coiler reeling, by detecting the coiler reeling depending on the magnitude of change of rotating speed of mandrel shaft rotated by mandrel motor. CONSTITUTION:Angular velocity omega of mandrel ML is detected by a tachogenerator TG, and differential value domega/dt is computed in a differentiating circuit D of load relay control system LRC. The output of the circuit D is input into a relay amplifier RA, and load relay LR is operated by this amplifier RA output. A control value RB is set in the amplifier RA as bias value, and then the differential value is larger than this value, that is, when domega/dt>RB, the amplifier RA is put into operation. Further, in order to enhance the reliability of the operation, an interlock X for arrival of strip is set in the amplifier RA, and when the interlock X is OFF, the amplifier RA is designed not to deliver an output.
