[0015] In this embodiment, the coil transport vehicle system includes a wire encoder 1 for detecting the position of the coil transport vehicle, a stop limit switch 2 for the coil transport vehicle at the exit of the first coiler, a deceleration limit switch 3 for the coil transport vehicle at the exit of the first coiler, a deceleration limit switch 4 for the coil transport vehicle at the exit of the second coiler, a stop limit switch 5 for the coil transport vehicle at the exit of the second coiler, a hydraulic motor 6, a coil transport vehicle steel coil saddle 7, a coil transport vehicle cable drag chain 8, a coil waiting position 9 for the exit of the first coiler, a C-type coiler 10 for the exit of the first coiler, a waiting position 11 for the exit of the second coiler, a C-type coiler 12 for the exit of the second coiler, an anti-derailment mechanical stop 13, a walking beam 14 and a walking beam steel coil saddle 15, wherein:
[0016] The wire-drawing encoder 1 for position detection of the coil transport vehicle is used for position feedback of the vehicle, and adopts the ENA58IL-S10CA5-1213SG1-RC1 multi-turn high-resolution encoder and the matching ECN30PL-10A1A-X2:NN wire-drawing mechanism.
[0017] The No. 1 coiler exit coil transport car stop limit switch 2, the No. 1 coiler exit coil transport car deceleration limit switch 3, the No. 2 coiler exit coil transport car deceleration limit switch 4 and the No. 2 coiler exit coil transport car stop limit switch 5 are proximity switch products of Shanghai Zuochuan Electronic Technology Co., Ltd., which are used for the position positioning and high and low speed switching of the steel coil car. At the same time, the proximity switch and the wire encoder position feedback are used as backup for each other to improve the reliability and stability of the coil transport car system.
[0018] The coil transport vehicle 16 is a four-wheel structure, and is equipped with a coil transport vehicle steel coil saddle 7 with four pillars for carrying the steel coil, so that the C-type coil loading device can load the steel coil onto the coil transport vehicle saddle axially and the walking beam can take the steel coil from the coil transport vehicle in the radial direction of the steel coil;
[0019] The hydraulic motor 6 is connected to two driving wheels of the coil transport vehicle 16 through a reducer and a connecting shaft. The hydraulic motor 6 drives the driving wheels to realize the forward and backward movement of the coil transport vehicle 16 on the coil transport vehicle track 17.
[0020] Arc-shaped anti-derailment mechanical stoppers 13 are installed at both ends of the coil transport track 17;
[0021] The hydraulic oil pipe is connected to the hydraulic valve station and the hydraulic motor 6 through the cable drag chain 8 of the reel transport vehicle; the proportional valve is installed on the hydraulic valve station to control the forward and reverse rotation of the hydraulic motor 6.
[0022] The coil transport car 16 has two coil receiving positions, namely: the coil receiving position at the exit of the No. 1 coiler (abbreviated as: the No. 1 coil receiving position) and the coil receiving position at the exit of the No. 2 coiler (abbreviated as: the No. 2 coil receiving position). In order to improve the coil transport efficiency, the coil receiving position at the exit of the No. 2 coiler is also set as the coil delivery position, which greatly improves the efficiency of the coil transport car. When the No. 1 coil receiving position requests to receive the coil, the coil transport car goes to the No. 1 coil receiving position to receive the coil, and after receiving the coil, it goes to the coil delivery position to deliver the coil. When the No. 2 coil receiving position requests to receive the coil, the coil transport car goes to the No. 2 coil receiving position to receive the coil, and after receiving the coil, since this coil receiving position is the coil delivery position, it remains motionless until the steel coil is taken away. The material tracking program is used to determine whether the coil transport car is occupied, and the steel coil detection device on the steel coil position on the coil transport car is cancelled to reduce the failure points and improve the operation stability of the coil transport car.
[0023] The coil car request signal is generated according to the coil material tracking; when the coil transport car receives the request signal and runs towards the exit of the No. 1 coiler, the coil transport car deceleration limit switch at the exit of the No. 1 coiler detects a signal and then switches to low-speed operation; after the coil transport car stop limit switch at the exit of the No. 1 coiler detects a signal, the coil transport car stops notifying and waiting for the C-type coiler to coil up; after the coiling is completed, the coil transport car runs in the reverse direction at high speed; after the coiling is completed, the coil transport car deceleration limit switch at the exit of the No. 2 coiler detects a signal and then switches to low-speed operation; after the coil transport car stop limit switch at the exit of the No. 2 coiler detects a signal, the coil transport car stops waiting and notifies the walking beam The coil on the coil transport car is taken away; the coil transport car receives the request signal and runs towards the exit of the No. 2 coiler. After the deceleration limit switch of the coil transport car at the exit of the No. 2 coiler detects the signal, the coil transport car switches to low speed operation. After the stop limit switch of the coil transport car at the exit of the No. 2 coiler detects the signal, the coil transport car stops notifying and waiting for the C-type coiler to roll up. After the rolling is completed, the coil transport car stops waiting and notifies the stepping beam to take the coil on the coil transport car; the coil transport car control program automatically checks the positions of the two C-type coilers and the stepping beam. The coil transport car is only allowed to move when the above equipment is in the original position (the equipment is in a safe position without mechanical interference). The wire encoder detects the position of the coil car in real time and displays it on the HMI screen, and generates two virtual deceleration limit signals and two stop limit signals through the position comparison in the program as backup for the proximity switch signal. The source of the position feedback detection signal can be quickly switched through the HMI screen selection to ensure the stable operation of the system.
