Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to article processing equipment in which an automatic three-dimensional storage space is provided between three or more processing steps in close proximity to each other, and the operating rate of each processing step is maintained at a high level. be.

Generally, when processing an article, it often involves two or more connected processing steps. In this case, on a so-called specialized single-item processing line that processes only a specific single item, the equipment capacity for each processing process is appropriately balanced, and there is almost no work-in-progress between each processing process. .

However, if there is a change in the dimensions of the workpiece or the product type, especially if intermediate processing is performed between consecutive processing steps, for example, in the manufacturing process of steel products, the hot rolling process and In the subsequent product refining process, the capabilities of each process are not necessarily balanced depending on the product type and size, etc., and there are cases in between which require special shearing or heat treatment for a part of the material. In this case, there is a difference in efficiency between the respective processing steps, and it is common that work-in-progress occurs in the workpiece between these steps.

It is customary for these work-in-progress products to be piled up in a vacant space within the factory. However, when the workpiece described above is a long or heavy product such as steel, there are various problems such as thorns in the non-linking of the work in progress.

That is, (1) It requires a large amount of space as a work-in-progress storage area.

(2) Hazardous work is involved in handling such as lifting loads.

(3) Noise is generated during handling, which creates a poor working environment, especially for steel pipes.

(4) Requires a large number of personnel.

On the other hand, when dealing with these processes by directly linking them, the overall operating rate of the processing line will be limited by the low-efficiency processing processes, so the equipment capacity of each process will be excessive compared to the average required capacity. There is a need. In particular, when there is an intermediate processing step between these steps to process a part of the workpiece, the above-mentioned work-in-process storage area is required before and after this intermediate processing step, and the above-mentioned day-to-day storage is required. In addition to causing problems, the production process is disrupted due to this work in progress, leading to delays in delivery dates and the like.

As described above, in equipment having three or more adjacent processing steps, many problems occur in terms of operation rate and other aspects. To address this problem, the same applicant has proposed an innovative solution. (Japanese Unexamined Patent Publication No. 52-137871) To explain this content using broken lines using FIG. 4, the first processing equipment 11, the second processing equipment 2, and the third processing equipment 15
In between, an automatic three-dimensional storage facility 5 that can be shared by each process is arranged, and work-in-progress products are exchanged via the automatic three-dimensional storage facility 5.
Since it is the same as in Figure 3, it will be explained later. ) With such equipment, the above-mentioned problems can be solved all at once. However, in this facility, there are multiple transfer machines 8.8"i each with automatic storage space 5
Since the entrances and exits are located in the same building A and A' (that is, they are located on the same running line), the following problems occur.

(1) When multiple transfer machines interfere with each other when loading and unloading work-in-progress at the entrance/exit side of an automatic three-dimensional storage facility, the effective operating rate is low and the peak capacity of each processing process cannot be followed. was there. (Effective operating rate of about 60% to 65 inches per machine) For this reason, when increasing the capacity of intermediate processing steps (for example, heat treatment steps), the transfer function was severely restricted.

(2) Even if it were necessary to increase the number of processing steps associated with an automatic multi-level storage facility, it was difficult to increase the number of processing steps because of the increase in the travel time cycle of the transfer machine and the decrease in capacity due to interference.

In view of these circumstances, the present invention: (1) Arranges the transfer machines so that they can operate independently to obtain a high operating rate. (Eliminates interference between multiple transfer machines, making it possible to ensure an effective operating rate of 95 cm or more per machine.) ■ Arrangement of transfer machines so that they can operate simultaneously makes it possible to keep up with the doubling of processing process capacity. shall be.

■ The transfer machines are arranged so that they can operate independently and simultaneously, making it possible to double the number of processing processes attached to the automatic three-dimensional storage facility.

The working pitch in each process is the size of the workpiece.

Although it varies depending on the shape or property, for example, in the rolling process 300P/Hr to 1800P/Hr1 in the heat treatment process 60P/Hr to 150P/Hr, it varies greatly even in the same processing process, and the difference between the processes The difference is large, and transport equipment such as transfer machines are required to have an extremely high transport capacity during peak hours. In this case, even if the number of transfer machines is increased in one transfer machine building, the mutual interference between the transfer machines will only increase, and a significant improvement in the carrying capacity of the transfer machines cannot be expected, and the capacity of each process will increase. must be suppressed. According to the present invention, this transfer machine building is divided into two
By using two or more transfer machines, interference between the transfer machines can be avoided, and the capacity of each process can be avoided due to the carrying capacity of the transfer machines.

From the above points, by using the present invention even in processing equipment that has a large number of processing steps and requires high efficiency, excessive capital investment can be avoided. It is possible to suppress, control, and maximize the equipment capacity of each process.
