Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is directed to the loading process after the extrusion process of aluminum or aluminum alloy extruded shapes (hereinafter referred to as shapes), to the surface treatment process through artificial aging. The present invention relates to a process for automating the previous loading/unloading process, as well as equipment and transport racks used therein. [Prior Art] Conventionally, in the extrusion process, the extruded and cut to predetermined length sections are loaded onto a transport rack by stacking the sections directly on top of the preceding sections via spacers. It was hot. This method has the disadvantage that the sections at the bottom of the stack are likely to be damaged by the load of the sections themselves, or due to shifting during transportation. In addition, in the extrusion process, the shapes extruded and cut into predetermined lengths are stacked on a transport rack, subjected to artificial aging treatment, and then stacked on the transport rack again and supplied to the surface treatment process. Considering the entire process, automation of the process of loading the shaped materials onto the transport rack is proposed in Japanese Patent Application No. 111947-1983 (Japanese Patent Application Laid-open No.
68468), Japanese Patent Application No. 51-97974 (Japanese Patent Application No. 53-23481)
No.), Patent Application No. 1986-86144 (Japanese Unexamined Patent Publication No. 12231/1983)
This is possible with the equipment disclosed in
The loading and unloading process of supplying the artificially aged shapes from the transport racks stacked therein to the surface treatment equipment is a manual process performed by at least two workers. The material was taken out and supplied to the surface treatment equipment. [Problems to be Solved by the Invention] The present invention solves the above-mentioned problems, namely, that the shapes stacked on the transport rack are damaged by their own load or by the load being dislocated during transport. The aim is to eliminate this problem and achieve automation of all processes in which the shaped material on the saw table is sent through an artificial aging treatment process and then to a surface treatment process. [Means for Solving the Problems] Therefore, in the present invention, a new shape material transport rack is provided, and the method of loading the shapes onto this rack, aging treatment in the loaded state, and completion of the treatment is provided. It teaches a cyclical reuse process in which the subsequent sections are loaded and unloaded, and then transported to the surface treatment process, as well as empty racks are returned to the loading process.

A spacer supply device and a loading device are provided between the saw table and the heat treatment furnace in the rear equipment, and a spacer recovery device and a loading and unloading device are provided between the heat treatment furnace and the surface treatment device, the loading device, The heat treatment furnace and the loading/unloading device are connected by a rack transport conveyor device, and firstly, the loading device transports the sections onto the rack via spacers, one step at a time at equal pitches at intervals according to the height of the sections. The shapes are stacked in layers (hereinafter referred to as stacking one layer at a time via spacers) and subjected to artificial aging treatment in a heat treatment furnace. After the treatment is completed, the shapes are loaded and unloaded together with spacers from a transport rack by a loading and unloading device. , separate the shapes one by one from the bottom surface, align the tips of the shapes,
By correcting the inclination of the profile so that it is perpendicular to the transport direction, and feeding the profile to the surface treatment equipment at equal intervals depending on the shape, the loading process can be improved. The process, which was only partially automated, has now been automated, from the loading process to surface treatment through artificial aging. (Example) Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

Following the frame hanging process, there is a recovery device for spacers that are no longer needed as the shapes are sequentially supplied to the surface treatment device.
After loading and unloading the sections in the transport rack, the sections are separated one step at a time from the plane, the tips of the sections are aligned, the orientation of the sections is corrected so that it is perpendicular to the transport direction, and the The loading/unloading device for sequentially supplying the materials to the surface treatment device at equal intervals is a rack conveyor device that conveys the transportation racks between the loading device, the heat treatment furnace, and the loading/unloading device. The figure shows a transportation rack, and according to the present invention, the sections stacked on this rack are protected from damage at the bottom by the load of the sections themselves, or by the load collapsing during transportation. All processes from loading to surface treatment through artificial aging treatment are automated. The reference symbol in the figure is a return rack transport conveyor device for returning empty transport racks to the loading device after being sequentially supplied to the surface treatment device. The relationship between the above devices will be described below.
