Description

[0001] Unmanned automatic rebar bending machine [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic unfolding apparatus for automatically bending a high-strength reinforcement bar in an unmanned automated manner without inputting a worker.

Generally, reinforcing bars are the skeletons of structures that are installed at construction sites or industrial sites in order to reinforce mechanical strength.

These reinforcing bars are manufactured in a rod shape or a roll shape having a predetermined length and then bent and bent in a shape corresponding to the shape of the structure at a construction site or a processing factory.

On the other hand, when bending high-strength reinforcing bars having a weight of 50 kg or more, it is not easy to perform banding with a work force. Therefore, a reinforcing banding device is used.

However, in order to bend a high-strength reinforcing bar using a reinforcing banding device, at least three skilled workers should be placed at regular intervals along the longitudinal direction of the reinforcing bar, and then the reinforcing bar should be lifted and placed on the upper part of the reinforcing bar-

In other words, when using a conventional reinforcing banding apparatus, it is necessary to repeatedly carry out a very difficult work requiring three or more skilled workers at the same height to carry the reinforcing bar at a certain height at the same time.

Therefore, it is necessary to handle and transport heavy reinforcing bars directly by several workers. This causes workers' musculoskeletal diseases, increases fatigue of workers, causes many safety accidents and labor shortage, There is a problem that a plurality of workers are charged simultaneously and labor costs are also greatly burdened.

Accordingly, it is urgent to improve the structure of the reinforcing bar bending apparatus so that a high-strength reinforcing bar can be quickly and accurately banded without an operator.

Therefore, when the cylinder 43 is operated and the link arm 42 is rotated upward, the reinforcing bars R prepared in the preparation preparing stand 31 are introduced into the loading groove portion 42c while being rolled. At this time, the reinforcing bars R introduced into the insertion groove portion 42c are not separated from the input groove portion 42c due to the stepped portion with the insertion projecting portion 42b.

Then, when the link arm 42 rotates downward again and returns to the original position, the reinforcing bars R introduced into the inside of the loading groove portion 42c are also moved downward and rolled so as to be guided by the guiding portions 50 To the bending process position of the bending portion 60 to be bent.

The input unit 41 is provided at the front of the supply unit 10 so that the position and the interval of the link arm 42 can be adjusted according to the length of the reinforcing bars R, And is movable and fixed on the rail (44).

That is, the banding header 61 is operated when the driving unit is operated through the operation of the operator in a state where the reinforcing bars R are inserted between the rear guide block 61c and the front guide block 61d that are the bending processing positions of the reinforcing bars R The banding arm 61i is moved along the guide shaft 61g along the central axis roll 61f with the banding arm 61h reciprocating in the predetermined radius around the central axis roll 61f, (61f) side so as to perform the banding process.

The inclination and the length of the rear guide block 61c and the front guide block 61d are set to be greater than the inclination and length of the rear guide block 61c of the center guide block 51, The position between the rear guide block 61c and the front guide block 61d corresponds to the position of the guide groove portion 51c of the center guide block 51 and corresponds to the inclination and length of the front guide block 51a and the forward reclining guide portion 51b .

The front guide block 61d is configured to be movable and fixed in the forward and backward directions on the flat plate 61b so that the distance between the rear guide block 61c and the rear guide block 61c can be adjusted in accordance with the diameter and quantity of the reinforcing bars R.

On the other hand, the banding head 61 can adjust the banding radius from several tens of mm to several hundreds of millimeters. Since the distance adjustment block 61j for adjusting the distance between the bending arm roll 61i and the roll shaft 61e is provided between the bending arm 61h and the bending arm roll 61i while the center axial roll 61f can be replaced It is possible.

Therefore, the interval between the bending arm 61h and the bending arm roll 61i is set to correspond to the bending radius after replacing the circular central rib 61f or the elliptical central rib 61k, which is set to the roll shaft 61e, The banding radius can be easily adjusted by moving the position of the banding arm 61i through the distance adjustment block 61j. (In Fig. 7, the circular central axial rail 61f and the elliptical central axial rail 61k are shown together)

The bending head body 61a is installed on the setting rail 44 so as to be movable and fixable such that the bending head 61 is adjusted in position and spacing in accordance with the length of the reinforcing bar R like the link arm 42. [

It is to be noted that the setting rail 44 may be provided with a setting ruler (not shown) to easily identify the position and spacing of the bending head 61 so that the length and diameter of the bending rod 61, the bending radius of the bending rod 61, The work for setting the position and the interval of the bending head 61 according to the diameter and the radius of the roll shaft 61e can be completed quickly.

The discharging part 70 is provided on the bending part 60 and discharges one or more reinforcing bars R which have been bent by the bending part 60 to a product basket part 80 to be described later.

At this time, the discharge portion 70 is composed of the link arm 42 constituting the charging portion 40. That is, the link arm 42 is included in the charging unit 40 and functions as a charging unit.
