摘要： PURPOSE:To safely and surely carry out scrap disposal at a lower instalation cost with a simple maintenance procedure, by opening and closing the bottom of a bucket carrier veheicle recirpocating between a scrap storing position and a scrap discharging position so that the store scrap may be discharged without the carrier vehicle being entirely overturned. CONSTITUTION:Auxiliary wheels 9 are attached to the bottom plate 10 of a bucket carrier vehicle 1 inside of main wheels 8 provided at both ends of the carrier vehicle 1. When the bucket carrier vehicle 8 comes to a predetermined position above a pit 4, the auxiliary wheels 9 are positioned on movable rails 3a which are turned and lowered by means of a bottom plate opening and closing device A while the main wheels 8 are positioned on stationary rails 3. The bottom plate opening and closing device A turns and lowers the movable rails 3a in association with the extending and retracting motions of an actuator 12a so that the bottom plate 10 are inclined together with the movable rails 3a to open the bottom section of the vehicle. Accordingly, scrap is discharged through a chute 5 into a main bucket 6.

摘要： PROBLEM TO BE SOLVED: To prevent generation of an abrasion on the end surface of a coil caused by the displacement of the cores of a coil lifter and a metal strip coil put at the down end.
SOLUTION: The metal strip coil lifter has an open/close arm 4 with horizontal suspending parts 3 facing each other at the bottom of vertical parts 2 hanging from left and right sides of the main body 1 of the lifter. In the metal strip coil lifter, a brush support body 10 is hung oscillatably facing the inner side 2a of each vertical part 2 of the open/close arm. A brush 11 is attached on the side surface 10b of the brush support body 10 so that the top of the strands projects forward from the inner side surface 10a of the brush support body 10. Further, a spring 12 is connected between the brush support body 10 and the vertical part 2 of the open/close arm, and a limit switch 13 is mounted for detecting the contact of the brush support body 10 and the vertical part 2 of the open/close arm.

摘要： PROBLEM TO BE SOLVED: To provide a sleeve feeder which is capable of efficiently feeding sleeves different in length as well as those identical and which is also easy to be automatized, in a production line for many kinds in small quantities. SOLUTION: Sleeves 13-16 on an inclined placing face are centered one by one successively, thereby enabling them to be dispensed using the same sleeve feeder A even if the sleeves 13-16 are different in length. In addition, in the case where the sleeves 13-16 transferred to the feeder A by a hanging means 18 are shifted to the front and the rear and not in parallel, they are easily corrected for the parallel by a sleeve correcting stopper 17, which enables the centering to be performed easily and surely thereafter.
