Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precut system for automatically performing various kinds of processing on wood to preliminarily process the constituent wood of a wooden building.

[0002]

2. Description of the Related Art A precut system is used to preliminarily perform a cutting process for assembling on the wood mouth and side surfaces of a wooden structure, and if the wood is carried in through a carry-in port, a series of desired The processing is automatically performed sequentially and is carried out from the carry-out port. Such a precut system generally has a plurality of processing devices for performing various cutting processes, and a conveyer conveyor that connects these processing devices, and by a control means composed of a computer,
It is configured to perform a predetermined cutting process on the wood conveyed to each processing device.

However, in the general precut system described above, since the processing lines consisting of the respective processing devices and conveying means are arranged in series, for example, even wood that does not require wood cutting has a wood cutting process. Since it has to be passed through the device, and since the ones with different total processing times are conveyed in sequence at random, if the wood with a short total processing time is conveyed after the wood with a long total processing time, There are various problems such as the accumulation of wood in the conveying means.

In order to cope with such a problem, a precut system in which processing lines each including a processing device and a conveying means are arranged in parallel is disclosed in, for example, Japanese Unexamined Patent Publication No. 4-331052.
It is disclosed in the publication. According to such a conventional pre-cut system, the processing lines that are arranged in parallel can bypass the processing devices that do not require processing, and overtake the wood that has been loaded first and the wood that is loaded later. The pre-cut can be carried out efficiently as a whole system.

[0005]

However, in the above-mentioned conventional precut system, by disposing the processing lines in parallel, it is possible to bypass the processing apparatus for unnecessary processing and to pass the preceding wood. Since all the processing equipment and the transportation means are arranged in the same horizontal plane, the degree of freedom in changing the processing line is still poor,
There was a problem that the desired flow of the desired wood was insufficient.

That is, when the number of woods flowing in the processing line is small, even the above-mentioned conventional precut system can cope with it to some extent (the bypass and overtaking effects are exhibited), but various processing is required. In the case where a large number of timbers to be flowed, a plurality of timbers with different total processing times flow into the bypass line, or when it is necessary to overtake a plurality of timbers that flow ahead,
There is not much freedom in selecting the processing line recombination, and the response becomes insufficient.

On the other hand, in order to deal with such a defect,
Although it is conceivable to add a bypass line or the like, the installation space of the system increases correspondingly, making it difficult to introduce it into a limited space such as a factory. That is, since the processing device and the conveying means are all arranged on the same plane, if a bypass line or the like is additionally installed, the installation space of the system is required for the installation space.

The present invention has been made in view of the above circumstances, and improves the degree of freedom in selection of recombination of a processing line and conveys wood most efficiently, thereby enabling efficient processing as a whole system. As well as being able to do
It is to provide a pre-cut system that can reduce the installation space.
