Abstract

PURPOSE:To obtain a device capable of performing a series of unmanned operation by a method wherein straight rods are sorted into groups by their size and length and divided into designated numbers by their length and the straight rods in a take-away area of a shelf arranged three-dimensionally are taken away to be fed to a binding machine. CONSTITUTION:Varying length materials 20 are fed to bring the ends thereof into contact with an edge true-up member 32 of a varying length material sorter 13 located immediately before a shear 1 and assembled and sorted into groups according to their length by a varying length material grouping member 31 provided at different distances from the edge true-up member 32. The straight rod materials are cut by the shear 1 into a predetermined length. The cut straight rod materials are temporarily assembled by a fixed length material assembling member 33 of a dimension selecting device 3. The fixed length material assembling member 33 sends a necessary number of the cut fixed length materials to later process and holds the rest of them and its timing action is so controlled as to retard the subsequent feeding thereof. The straight rod materials sent out from the dimension selecting device 3 are placed on a shelf 7 by a lifter 5 and a pusher 6 and divided into groups by their size, transferred per bundle to a take-away area and such bundles are taken away by a shift shelf 8 and a down transfer 9 and bound by a binding machine 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an automatic method for processing straight bars in factories that handle straight bars (straight bar materials) by performing metal processing, hot rolling, cold working, etc. Relating to a binding device.

[Conventional technology]

Straight bars are shipped in bundles with specified dimensions (length and cross-sectional dimensions).

Conventionally, there are two types of devices for sorting straight bars, collecting them by length, and bundling them: a planar arrangement type device and a vertical arrangement type device. The planar arrangement type device includes, for example, N types a (N=S to 10) of collecting cradles corresponding to the types of lengths to be sorted. Straight bars sorted into specified lengths are sequentially fed into this collecting cradle from the top. After that, collect the pieces into the specified number and tie them together. This planar arrangement type device has the following drawbacks.

■A vast installation area is required because N types of cradles are arranged on a flat surface.

■Since the function of arranging the specified number of pieces and the function of putting together the pieces must be separated, the number of devices is large and the area required is large.

■It is difficult to serialize the series of operations of sorting, grouping, and bundling straight bars into cradles arranged on a flat surface.
