Description

  The present invention relates to a reinforcing bar processing facility provided with a reinforcing bar cutting machine for cutting a reinforcing bar into a predetermined length and a reinforcing bar bending machine for bending at least one end of the reinforcing bar.

  Conventionally, a rebar cutting machine and a rebar bending machine are generally installed separately and used individually (it is a well-known technique and literature cannot be shown).

In the above-described conventional rebar processing equipment, the first processed rebar cut by the rebar cutting machine has to be taken out by human power and supplied to the rebar bending machine, which is laborious.
Therefore, in order to continuously perform the bending process by the reinforcing bar bending machine after the cutting of the reinforcing bar by the reinforcing bar cutting machine, the reinforcing bar supplying apparatus that supplies the unprocessed reinforcing bar to the reinforcing bar cutting machine, and after the cutting from the reinforcing bar cutting machine The first processed rebar is taken out and provided away from the rebar cutting machine. The rebar supply device, the rebar cutting machine, and the first transfer conveyor are arranged in the longitudinal direction of the rebar, and the first transfer is performed. It is possible to arrange a reinforcing bar bending machine on the extension line of the conveyor.
In this case, there is a possibility that the entire equipment becomes long and it is difficult to secure the installation location, and there is a problem that a manager must be arranged for each of the reinforcing bar cutting machine and the reinforcing bar bending machine, which requires a lot of manpower. there were.

  Accordingly, an object of the present invention is to provide a reinforcing bar processing facility that solves the above-described problems, prevents an increase in length of the facility, and reduces the number of personnel required for the facility.

  The first characteristic configuration of the present invention is a reinforcing bar processing facility provided with a reinforcing bar cutting machine that cuts a reinforcing bar into a predetermined length and a reinforcing bar bending machine that bends at least one end side of the reinforcing bar. A reinforcing bar supply device for supplying untreated reinforcing bars to the reinforcing bar cutting machine, a first conveying conveyor for taking out the first processed reinforcing bar after cutting from the reinforcing bar cutting machine and moving it away from the reinforcing bar cutting machine; and a first conveyor on the first conveying conveyor A second conveying conveyor that conveys one processed reinforcing bar to the reinforcing bar bending machine; and a third conveying conveyor that takes out the second processed reinforcing bar bent from the reinforcing bar bending machine and discharges the second processed reinforcing bar to a discharge zone. And the reinforcing bar cutting machine and the first transport conveyor are arranged in the longitudinal direction of the reinforcing bar, the reinforcing bar bending machine is arranged on the side of the reinforcing bar cutting machine, and the first processed reinforcing bar from the first transport conveyor. The second conveyor is formed so as to be laterally conveyed to the rebar bending machine, and the second processed rebar is conveyed to a discharge zone disposed on the side opposite to the first conveyor on the side of the reinforcing bar bending machine. The third conveying conveyor is formed in the area.

According to the first characteristic configuration of the present invention, by providing the reinforcing bar supply device, the first conveying conveyor, the second conveying conveyor, and the third conveying conveyor, from the cutting of the reinforcing bar to the bending process is not required. The reinforcing bars are cut while moving linearly in the longitudinal direction from the reinforcing bar supply device to the first conveyor, and then the first processed reinforcing bars on the first conveyor are Because the second processed rebar is transported by the second transport conveyor to the rebar bending machine arranged on the side, and after the bending, the second processed rebar is transported to the lateral discharge zone by the third transport conveyor. In addition, the rebar can be processed without making the entire facility long.
In addition, by arranging the rebar bending machine on the side of the rebar cutting machine, one manager can stand between the two machines and perform management and operation operations, thereby reducing personnel assignment.

  According to a second characteristic configuration of the present invention, a reinforcing bar staying zone of the first processed reinforcing bar to be conveyed by the second conveying conveyor is provided between the reinforcing bar bending machine on the side of the first conveying conveyor. It is in.

  According to the second characteristic configuration of the present invention, in addition to being able to achieve the above-described operational effects according to the first characteristic configuration of the present invention, in general, the reinforcing bar bending machine is longer in processing time than the reinforcing bar cutting machine. Because it takes a long time, even if the rebar cutting machine is operated in accordance with the processing pace of the rebar bending machine, if the entire apparatus is stopped urgently due to disturbance of the processing pace such as trouble, At the time of resumption, the supply of the first processed rebar is not in time, and productivity is lowered. On the other hand, the present invention provides an emergency stop or operation delay based on a trouble of the reinforcing bar bending machine by providing the reinforcing bar staying zone of the first processed reinforcing bar between the first conveying conveyor and the reinforcing bar bending machine. Even if there is, the first processed rebar carried by the first conveyor and the second conveyor from the rebar cutting machine is retained in the rebar retention zone. The first machined rebar is supplied from the zone to the rebar bending machine, and the decrease in productivity can be suppressed.
