[Problems to be solved by the device]

 However, since the heat treatment furnace is a single unit, only one container can be set at the work discharge port, and the work such as springs usually fills the container in about 1 hour, and a different empty space is used each time. Not only is there a hassle of having to replace the container, but if it is forgotten, there is a risk that the work such as the spring will be damaged or the heat treatment furnace will malfunction. Therefore, it was impossible to drive for several hours at night or when unmanned, resulting in reduced productivity.

Further, if a separate auto stocker is installed, the space will be occupied accordingly, so there are two devices, a heat treatment furnace and an auto stocker, which become a hindrance when frequently changing, correcting or adjusting tools of an automatic molding machine. Had to be moved, which was extremely inconvenient.

Therefore, the present invention has been devised to solve the above-mentioned problems, and enables operation for several hours even at night or when unattended, so that productivity can be significantly improved. Not only that, when frequently changing, modifying or adjusting the tools of the automatic molding machine, it is possible to move only the heat treatment furnace that is in the way to make it extremely convenient, and a dedicated carry can be used to store the work-containing container. It is intended to provide a continuous heat treatment apparatus with an auto-stocker that can be easily transported to a storage location.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is an automatic forming machine for springs and the like in which a work input port such as a spring and a work discharge port are provided on the front end side and the rear end side of a mesh belt, respectively. A conveyor type heat treatment furnace connected to the rear side is formed, and workpieces such as springs which are continuously heat treated on the mesh belt are discharged from the work discharge port to the rear side and the lower side of the conveyor type heat treatment furnace. It is equipped with an automatic stocker that automatically stocks it.

[0007]

[Action]

 Then, by connecting the front side of the conveyor type heat treatment furnace to the rear side of the automatic molding machine such as a spring by the technical means as described above, the work such as the spring automatically molded by the automatic molding machine is conveyed. A workpiece such as a spring, which was loaded from the work inlet of the heat treatment furnace and continuously heat-treated on the mesh belt, was movably arranged in the front-back direction in the lower space of the conveyor heat treatment furnace from the work outlet. When a workpiece such as a spring reaches a prescribed amount or a prescribed number by a timer or counter and is accommodated in the empty container on the last side, at the same time, the workpiece-accommodated container and empty container move backward, and the empty container becomes the workpiece. The containers that have been set in the outlet are automatically stacked in a predetermined position by a lift.In this way, the workpieces such as springs are sequentially stored in each empty container and automatically To be able to stock.

Further, since the auto stocker is integrally mounted on the rear side and the lower side of the conveyor type heat treatment furnace, the occupied area is almost the same as that of the conventional heat treatment furnace only, and the tool of the automatic molding machine is frequently used. Only the conveyor type heat treatment furnace with integrated auto stocker should be moved when replacing, modifying or adjusting.
