Description

A retracting apparatus of arbor supporting column in a slitting machine

The present invention relates to an arbor end support column retraction mechanism of a slitter,

More particularly, the present invention relates to a mechanical configuration for providing an exchange path when exchanging a shear cutter in a slitter, which is a metal processing machine for cutting a metal sheet into straps and bands, and for configuring an automated line.

Metal plates of various materials and properties, such as steel plates, stainless steel plates, and aluminum plates, are processed and supplied to plate materials by primary manufacturers such as steel mills. Regarding the supplied metal sheet, which is a primary product supplied, a secondary processing material such as a strap shape and a band shape is manufactured by reprocessing for various purposes.

Particularly, the metal plate material of the strap or band body is a material for continuous press supply of various mechanical parts and electronic parts, and therefore, a dedicated processing machine for cutting the supplied metal plate material into strap shapes having various widths is required. Also for this purpose, a dedicated machine of various configurations is devised and is used as a slitter machine or a slitter (hereinafter, referred to as a “slitter”).

The most common configuration employed in most of the prior art or known known products of slitters is provided with arbors, which are also pairs of long length rollers that are parallel between a pair of opposing upright columns, On the arbor, a plurality of shear-type cutters, which are ring-shaped knives, are arranged with a plurality of equally spaced spacers, and a plurality of straps are simultaneously cut by driving a roller while supplying a metal plate material between the shear cutters. Most slitters have a similar configuration based on them.

The slitter of the basic configuration as described above is a very general configuration in the industry and is currently widely used in many steel mills and secondary processing plants.

Since the slitter cuts the plate into several straps at the same time, a very large shear force must be applied and the overall mechanism is quite large, so that a pair of individual arbors have a large number of ring-shaped, large diameter and weight shear cutters to replace or replace. It is not easy, and efforts are being made to automate it by hand because of its low efficiency and productivity and high risk of safety accidents.

In particular, the replacement of worn shear cutters must be made from time to time according to the continuous slitting of the sheet metal, and the replacement and management of these shear cutters is necessary because the multiple sheets of shear cutters arranged on the arbor must be replaced at the same time. And work efficiency is very important.

In the past, a worker performed manual replacement of the shear cutter, but recently, a series of products for shipping a multi-axis robot having a replacement hand has been shipped.

In the conventional slitter, as a means for replacing a plurality of shear cutters, the arbor end support column on one side is separated from the arbor and transported to the rear, and a plurality of replacement shear cutters carried by hand are replaced by hand, or the like.

Even in an automated line that provides a replacement arbor with a replaced shear cutter, there was an inconvenience of having to do manual work between arbors.

The arbor end support column evacuation mechanism of the slitter of the present invention further comprises a evacuation mechanism with respect to the arbor end support column on the free end side of the arbor having a plurality of shear cutters mounted on the conventional slitter line of this basic configuration. By providing

In a slitter for cutting and processing a metal sheet into a strap shape, it has a pair of arbors provided between a drive part column on a base housing and an arbor end support column in an axial direction opposite to the slitter of the drive part column,

The arbor, which is one end of the arbor, is rotatably mounted to the driving column, and the arbor free end, which is the other end of the arbor, is provided as a free end of the cantilever to be axially supported or released by the arbor end support column. In the ground;

The arbor end support column for axially supporting the arbor free end or releasing the axial support is worn by further having a retraction mechanism for retreating in the axial direction of the slitter after the axial support is released and again evacuating backward from the axial center of the slitter. It is a basic feature to form a complete automation line by providing a replacement space for replacing the old shear cutter and the new shear cutter.

Further, the evacuation mechanism, the x-axis moving mechanism is carried out by an X-axis guide and a pneumatic pneumatic cylinder for driving the arbor end support column extending from the end of the base housing to the drive housing further provided to the side;

The y-axis moving mechanism of the drive housing by the guide housing on which the drive housing is mounted, the Z-axis guide therebetween, and a hydraulic cylinder for driving.

Arbor end support column retraction mechanism of the slitter of the present invention of the above configuration;

By providing a retraction mechanism for the arbor end support column on the free end side of the arbor having a plurality of shear cutters mounted on the conventional slitter line,

The robot can further pursue the completion of the automation system that can enhance the cooperativeness with the preliminary cutter stack arbors equipped with a replacement shear cutter in advance, and improve the reliability of operation and safety by heavy goods. It has the usefulness to construct a complete automation line that can prevent accidents.
