A first abutting plate for positioning the position of the reinforcing bar by contacting the tip of the reinforcing bar at the time of cutting by the reinforcing bar cutting machine, and a conveyor device that conveys the part in a direction away from the reinforcing bar cutting machine A stopper device provided with a second abutting plate for positioning the rear end of the reinforcing bar by contacting the lower end of the first abutting plate by means of conveyance by the conveyor device. The first abutting plate is movably mounted in the longitudinal direction with respect to the reinforcing bar receiving table, and the first abutting plate is moved up and down in the vertical direction. 1 operation mechanism is provided, the rebar The reinforcing bar receiving table is attached to the receiving device main body so as to be swingable up and down to a reinforcing bar receiving position in which the reinforcing bar receiving surface of the stopping base is in a horizontal posture and a reinforcing bar discharging posture inclined in the radial direction of the reinforcing bar, A second operation mechanism for vertically swinging the reinforcing bar receiving table, a driving force transmission mechanism for transmitting a driving operation force from one driving device to the first operation mechanism and the second operation mechanism; Prior to swinging the reinforcing bar receiving stand to the reinforcing bar release posture by the two operating mechanisms, the reinforcing bar receiving device is configured to perform the upward movement operation of the first abutting plate by the first operating mechanism. An arm that is driven to swing around the swing center of the reinforcing bar receiving table by the driving device is provided, and a part of the first operating mechanism and a part of the second operating mechanism are configured to be shared by the arm. Therefore, the first abutting plate is moved up and down along with the contact of the arm. A first contact portion is provided on a support frame of the first abutting plate, and the arm, the first contact portion, and the support frame constitute the first operating mechanism, and the arm contact portion Accordingly, a second contact part for swinging the reinforcing bar receiving table from the reinforcing bar receiving position to the reinforcing bar releasing position is provided in the reinforcing bar receiving table, and the arm and the second contacting part the second constitutes a operating mechanism, with the to swing the rebar catch block reinforcing bars dumping orientation said arm by said second operating mechanism abutment to the second abutment, the rebar catch the swing stopper portion under the base surface portion stops its swing by abutment, provided in said catch device body, between the rocking stopper portion and the reinforcing bar catch platform undersurface portion, a compression spring At the tip of the arm. No matter whether the stopper device is changed to any position in the longitudinal direction of the reinforcing bar receiving table, the angle member is attached to the first abutting portion and the first member in accordance with the vertical swinging operation of the arm. There is a configuration in which the swinging force of the arm is transmitted in contact with the two contact portions .

本発明の第１の特徴構成によれば、駆動力伝達機構によって１つの駆動装置で第１操作機構と第２操作機構とを駆動操作するために、余分に駆動装置を設けずに済み、安価で軽量な装置に製作でき、しかも、第２操作機構により鉄筋受止台を鉄筋放出姿勢に揺動操作するのに先立って、第１操作機構による第１当て付け板の上昇移動操作を行うように構成してあることにより、夫々操作タイミングの異なった操作が簡単にできるようになる。   According to the first characteristic configuration of the present invention, since the first operating mechanism and the second operating mechanism are driven and operated by one driving device by the driving force transmission mechanism, it is not necessary to provide an extra driving device and is inexpensive. In addition, the first abutment plate can be moved up and down by the first operation mechanism before the second operation mechanism swings the reinforcing bar receiving stand to the rebar release posture. Thus, operations with different operation timings can be easily performed.

また、駆動装置によりアームを駆動揺動するだけで、鉄筋切断後に、初めにアームが第１接当部に接当して支持フレームを介して第１当て付け板を上昇させ、鉄筋受止姿勢の鉄筋受止台上の鉄筋を、第２当て付け板に接当するまでコンベア装置により搬送する。次に、アームを駆動揺動させて第２接当部に接当させて、鉄筋受止台を揺動させることで、鉄筋受止台は鉄筋放出姿勢になり、切断鉄筋は放出される。
従って、第１操作機構と第２操作機構の駆動操作を、兼用するアームの駆動揺動によって、異なったタイミングで簡単に行うことができる。
その上、前記揺動ストッパー部と前記鉄筋受止台の下面部との間に、圧縮スプリングを介在してあるために、前記鉄筋受止台の鉄筋受止姿勢から鉄筋放出姿勢への揺動時に、前記揺動ストッパー部に対する前記鉄筋受止台の下面部の接当に伴う衝撃を緩和するとともに、鉄筋放出姿勢から鉄筋受止姿勢への復帰を、スムーズに行える。 In addition, by simply swinging and driving the arm with the driving device, after the rebar is cut, the arm first comes into contact with the first abutting portion and raises the first abutting plate via the support frame, thereby rebar receiving posture. The reinforcing bars on the reinforcing bar receiving table are conveyed by the conveyor device until they contact the second abutting plate. Next, the arm is driven to swing and is brought into contact with the second contact portion to swing the reinforcing bar receiving table, whereby the reinforcing bar receiving table is in a reinforcing bar discharge posture, and the cut reinforcing bar is discharged.
Therefore, the driving operation of the first operating mechanism and the second operating mechanism can be easily performed at different timings by the driving swing of the arm that is also used.
Moreover, oscillation of between the rocking stopper portion and the reinforcing bar catch platform undersurface portion, to a compression spring are interposed, to reinforcing bar dumping orientation from the rebar catch base rebar catch position Sometimes, the impact associated with the contact of the lower surface portion of the reinforcing bar receiving table with the swinging stopper portion is alleviated, and the return from the reinforcing bar release posture to the reinforcing bar receiving posture can be performed smoothly.
