Description

[Detailed description of the invention] "Field of industrial application" This invention is a coil line that supplies coil material to a press. This invention relates to a coil car lifter device used for aligning holes.

``Prior art'' Conventionally, in a coil car, a stand on which the coil material is placed is fixed to the piston rod of a lift cylinder fixed to the vehicle body, and after loading the coil material on the stand, the coil car is advanced to the vicinity of the uncoiler drum. After raising the stand with a lift cylinder and aligning the center hole of the coil material with the drum, the coil car was further advanced to insert and mount the coil material on the drum.

``Problems to be Solved by the Invention'' In the conventional lifter device described above, a long lift cylinder protrudes from the bottom of the coil car body, so it is necessary to provide a deep pit between the rails on which the wheels on both sides run. In addition to the troublesome basic installation work,
The piping for the lift cylinder is easily damaged by the movement of the coil car, and when workers operate the coil car and lift cylinder to align the hole in the coil material with the drum of the uncoiler, they must look in from the side because they cannot stand between the rails. The work was complicated and dangerous. An object of the present invention is to eliminate these drawbacks and provide a lifter device that does not require pits and is easy to install and operate the coil car.

"Means and effects for solving the problem" The structure of the present invention is that two guide pins are set up at the rear side of the coil car with a gap between them, and a stand is provided on the guide pins so that the uncoiler can be moved up and down. A vertical fork guide is installed on the fuselage below the drum.
A fork whose base is connected to the fork guide so as to be able to rise and fall is extended toward the coil car, rollers are arranged on the top surface of the fork, a lift cylinder for raising and lowering the fork is provided in the body of the uncoiler, and a lift cylinder is installed on the coil car stand. After placing the coil material, move the coil car forward, temporarily stop the coil car when the tip of the fork is inserted below the stand, raise the fork with the lift cylinder, support the stand with the rollers of the fork, and rise. and align the center hole of the coil material with the uncoiler drum.
The system is characterized in that the coil car is moved forward and the mounting table is run on the rollers of the fork to load the coil material.

"Example" FIG. 1 and FIG. 2 show the structure of a lifter device for a coil car. A drum shaft 2 is rotatably supported on the upper part of the body of the uncoiler 1, and a drum 4 on which a coil material 3 is mounted is provided at the projecting end of the drum shaft 2. A pair of rails 5, 5 is provided on the floor extending from below the drum 4 in the direction in which the drum shaft 2 protrudes. A coil car 6 running on a rail 5 has wheels 7 driven by a motor 8 to freely move forward and backward toward the drum 4. Two guide pins 9, 9 are provided upright at the end of the upper surface of the coil car 6 on the side opposite to the uncoiler 1 with an interval in the width direction. A stand 10 for the coil material 3 is provided on the coil car 6, with one end thereof being guided by guide pins 9, 9 so as to be movable up and down, and the other end facing the uncoiler 1 and extending to a required length. A V-shaped slope 11 with a low center width is provided on the upper surface of the stand 10 so that the coil material 3 can be placed on the center of the coil car 6. Further, on the lower surface of the stand 10, pillow members 12, 12 are provided on both sides of the width and have a required height facing the running direction of the coil car 6. stand 1
It can be inserted below 0.

At the bottom of the uncoiler 1, fork guides 13, 13 facing vertically are provided.
Upper and lower rollers 15 rotatably provided at the base of the roller are guided up and down. The fork 14 is divided into two parallel pieces from its base and extends horizontally to a required length in the running direction of the coil car 6, and has a large number of rows of rollers 16 arranged on its upper surface to receive the bottom surface of the stand 10. Further, a lift cylinder 17 that acts upward is provided at the lower part of the body of the uncoiler 1, and the base of the fork 14 is connected to the piston rod of the lift cylinder 17.

When the coil material 3 is mounted on the uncoiler 1 with this configuration, the fork 1 is
4 to the lowered position, coil car 6 to fork 1
4 and load the coil material 3 onto the V-shaped slope 11 of the stand 10. Move the coil car 6 forward and the tip of the fork 14 will be placed on the stand 1.
When the coil car 6 is inserted between the pillow members 12 and 12 of 0, the coil car 6 is temporarily stopped. Subsequently, the lift cylinder 17 is remotely operated to raise the fork 14. The stand 10 supported on the rollers 16 of the fork 14 is guided by the guide pin 9 of the coil car 6 and raised, so that the center hole of the coil material 3 is aligned with the uncoiler 1.
The ascent is stopped when it is aligned with drum 4. Move the coil car 6 forward again and tighten the guide pin 9.
Push the stand 10 with the roller 16 of the fork 14.
The coil material 3 is inserted into the drum 4 by running the upper part.
When the fork 14 is lowered by a lift cylinder 17 and the stand 10 is placed on the coil car 6, the coil car 6 is retreated.

``Effects of the invention'' As is clear from the above explanation, according to the invention, the lift cylinder and fork are provided on the uncoiler, so there is nothing protruding downward from the coil car, and there is no need to provide a pit on the floor between the rails. do not have. Therefore, when loading the coil material on the uncoiler, the worker can stand freely between the rails, making the work easier and without danger to the worker. Since the piping for the lift cylinder is fixedly installed, there is little damage. The practical effects and benefits are great.
