BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic aligning and cutting apparatus for a reinforcing steel, and more particularly, to a reinforcing steel automatic aligning and cutting apparatus improved in productivity and efficiency by stably supplying reinforcing bars and recovering the remaining amount.

Generally, reinforcing steel is a construction material which mainly forms tensile strength by making iron rod, and it is one of the mechanical structures which is very important in civil engineering and construction engineering. At this time, the reinforcing bars are mainly made of carbon steel, and are made of reinforcing concrete structures combined with the concrete to be compressed. The reinforcing bar is divided into a deformed reinforcing bar formed of a bar having a projection of ribs and nodules on the surface thereof, and a circular reinforcing bar formed of a bar having a smooth circular shape without projections.

On the other hand, in order to use reinforcing bars in various industrial fields, it is necessary to cut reinforcing bars produced in the same standard to a certain length according to the required length. The process of sorting, sorting, cutting, and transporting these reinforcing bars was performed manually.

That is, one person aligns the reinforcing bars placed on the die so that both ends thereof are aligned with each other, and guides the reinforcing bars to the cutter, one person cuts the reinforcing bars guided by the cutter to a predetermined length, However, since the required manpower is increased, the labor cost consumed in the work is increased.

In addition, even if the cut reinforced bar is transported by a person, it is necessary to perform additional work, resulting in a decrease in productivity, and a safety accident occurs frequently during the transportation of the rebar due to the carelessness of the operator.

Accordingly, in order to improve the productivity and the economical efficiency, an automatic apparatus for sorting the reinforcing bar, which was manually operated, is arranged by a stepwise automatic separating feeder.

In this case, although the technique of arranging the ends of the reinforcing bars to be cut in line by the automated stepwise separating feeder and arranging them in a line and conveying them to the conveyor belt is devised, in the course of conveying the aligned reinforcing bars to the conveyor belt, The worker has to manually correct it by a separate manual operation, resulting in a problem of deteriorating productivity and economy.

On the other hand, a feed bar is provided to supply the cutting target reinforcing bars to the stepwise separating feeder. At this time, the reinforcing bars to be cut are provided in various sizes corresponding to the diameters, and the operator feeds the reinforcing bars to be cut to the feeder according to the standard, and proceeds the process of aligning and cutting the reinforcing bars to be cut.

However, in a case where a new process is continuously performed by supplying reinforcing bars to be cut which are different from each other in specifications, the operator must manually collect all the remaining amounts of the reinforcing bars to be cut used in the existing process. That is, after proceeding to cut the D10 specimens to be cut, the operator manually recovers the D10 specimens to be cut, which remain in the feeder, in order to carry out the process of cutting the specimens to be cut according to the D19 standard, The reinforcing bars to be cut of the reinforcing bars need to be supplied to the feeder.

Particularly, since the reinforcing bars to be cut are put in a large packed state, they are unpacked and supplied to the stepwise separating feeder. Therefore, excessive work time is required to manually retrieve the remaining amount of rebar to be cut after the cutting process The efficiency of the operation is lowered.

Further, there is a problem in that the productivity of the product deteriorates because it is impossible to carry out the cutting process of the reinforcing bars to be cut having different specifications during the recovery operation of the reinforcing bars to be cut used in the existing process.

Herein, the apparatus for automatically aligning and cutting the reinforcing bars 100 can perform a new process when the remaining amount of the reinforcing bars g is recovered. At this time, the residual amount storage device 90 may be provided to recover the remaining amount of the reinforcing bars g.

For example, after the first reinforcing bar g1 is supplied to the automatic rebar cutting and cutting apparatus 100 to perform the aligning and cutting process, the remaining amount of the first reinforcing bars g1 remains in the connecting feeder 10 It is necessary to supply the second reinforcing bar g2 with a new process. Here, it is preferable that the first reinforcing bars g1 and the second reinforcing bars g2 are reinforcing bars having different specifications.

At this time, the operator operates the separating type conveying portion 13 and the divided recovery conveying portion 91 in the direction opposite to the advancing direction, that is, in the direction of the remaining amount storage device 90 from the stepwise separated supply device D side So that the remaining amount of the first reinforcing bars g1 can be moved to the upper portion of the remaining amount storage device 90 and can be settled.
