Burr Mounted
Rewinding shaft of slitting machine
A plurality of cylinder bores formed in an outer peripheral surface of the rewinding shaft and terminating in the hollow interior; a plurality of pistons respectively received in the cylinder bores, such that heads of the pistons can be reciprocally moved in and out of the cylinder bores by pressurized liquid or gas fed to the hollow interior; and at least one rewinding ring removably mounted on the rewinding shaft such that an inner peripheral surface of the rewinding ring can contact the piston heads.
In a typical conventional slitting machine, a rolled raw material is fed by a feeder, then slit into strips having a desired width or widths by a cutter at one stage of the process for feeding the material, and then rewound on a rewinding shaft. For rewinding the required number of strips, a corresponding number of rewinding drums are locked to only one rewinding shaft by suitable means such as a key so that the drums are prevented from slipping and thereafter, the strips are fixedly rewound on the rewinding drums.
However, this prior art has the following problems. First, burrs are usually generated on the edge of the slit materials (strips). When the strips with burrs are simultaneously rewound on the same rewinding shaft, each strip is subjected to different tensions because each strip has a different diameter due to difference in thickness of the burrs. Therefore, the strips rewound on the rewinding shaft (i.e., coils of the strips on the rewinding shaft) tend to get loosened. In order to retighten each coil of the strips, the coils of the strips, which were once rewound on the rewinding shaft, are removed from the shaft and retightened using suitable tools. During the process of this retightening operation, the strips (i.e., coils) often get scratched to thereby degrade their quality. Also, the retightening of the strips is a troublesome and hard work.
There is known a looping method as one way for preventing the loosening. In this looping method, the strips are pressed hard by pads or the like immediate before the rewinding shaft. When a large driving force is applied to the rewinding shaft, the strips are rewound in their tightened states on the rewinding shaft under the effect of a drawing phenomenon against the braking force exerted by the pads immediately before the rewinding shaft. However, the strips having a reduced diameter due to a difference in thickness of the burrs which are not the same in rewinding length to other strips and tend to hang down immediate before the pads. This hanging amount of each strip is increased in proportion to the increased rewinding length thereof. As a countermeasure, a deep hole extending more than ten meters is formed in the surface of the earth to receive the hanging portions of the strips. Therefore, the installing costs of the slitting machine are increased and a very large installation space is required. In addition, the strips are liable to get scratched under the effect of the drawing phenomenon caused by the pressing of the pads.
The present invention has been accomplished in view of the above problems inherent in the prior art. It is, therefore, a general object of the present invention to provide, in order to resolve the above problem, a rewinding shaft of a slitting machine, in which a plurality of elongated materials (i.e., strips) can be simultaneously rewound with a constant tension and without being allowed to hang down at one end thereof.
To achieve the above object, there is essentially provided a rewinding shaft of a slitting machine comprising a rewinding shaft body having a hollow interior extending axially, the hollow interior being exposed outside at one end of the rewinding shaft body; a plurality of cylinder bores formed in an outer peripheral surface of the rewinding shaft body and terminating in the hollow interior; a plurality of pistons respectively received in the cylinder bores, such that heads of the pistons can be reciprocally moved in and out of the cylinder bores by pressurized liquid or gas body fed to the hollow interior; and at least one rewinding ring removably mounted on the rewinding shaft body such that an inner peripheral surface of the rewinding ring can contact the piston heads. Preferably, the openings of the cylinder bores are arranged in a spiral pattern on the outer peripheral surface of the rewinding shaft body. Each piston may be provided with an O-ring.
