BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden building material processing apparatus that controls processing using barcode information.

0002

BACKGROUND OF THE INVENTION Conventional construction methods are also called frame construction methods, and require various types of tenon processing (joint processing) to join each structural member. Structural materials can be broadly classified into columns and horizontal members installed horizontally between the columns, but since each structure has a different shape, it takes a considerable amount of time and effort to process them. Therefore, various automatic processing devices have been proposed for the purpose of shortening processing time and improving processing accuracy. For example, the following is disclosed in Japanese Patent Application Laid-open No. 171301/1983.

That is, as shown in FIG.
is carried into the processing line by the carry-in conveyor 42, and the end thereof is first cut into a predetermined length by the cutting machine 43. Then, the workpiece 41 whose end portion has been cut is subjected to processing such as drilling on the upper and lower surfaces by a top and bottom surface processing machine 44 located on the upstream side, and then a dovetail groove is formed on the side surface of the workpiece 41 by a side surface processing machine 45. Apply tenon processing such as. and,
Finally, a wood edge processing machine 46 located downstream applies dovetail and tenon processing to both end faces of the workpiece 41, and all of these processing operations are automatically performed by instructions from a control device (computer) not shown. It will be held on. Then, the workpiece 41 that has been completely processed is carried out of the line by a carry-out conveyor 47.

[Problem to be solved by the invention] In the above processing device,
Materials to be processed are passed through all processing machines regardless of whether they are processed or not. For example, if a structural material requires processing only on the wood end, it will have to pass through an unnecessary top and bottom surface processing machine and a side surface processing machine, and if a structural material has been processed up to the side surface processing machine, it will need to be machined at the wood end. It cannot be carried out unless it passes through a processing machine, and from a logistics perspective, there is a problem that processing efficiency is poor due to unnecessary passage and stagnation due to this.

[0005] As a countermeasure to the above-mentioned problem, it is possible to connect parallel loading and unloading conveyors to each processing machine.
In this case, since the processed material flows randomly,
This raises the problem that computer management becomes difficult. The present invention has been made by focusing on the problems of the prior art described above, and provides a wooden construction material processing device that can perform efficient tenon processing by attaching barcodes to each processed material and managing it using a computer. This is what we are trying to provide.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a wooden building material processing apparatus according to the present invention is constructed as follows. In other words, the gist is that the length cutting machine, side processing machine, and end processing machine are connected by a series conveyor line and a parallel conveyor line branched from this conveyor line, and the processing transferred by the conveyor line is A barcode is affixed to the appropriate location on the material, and a barcode reader that reads this barcode is installed upstream of each of the above processing machines, and program data is extracted from the control device using the barcode information read by the barcode reader. The control drive of each of the processing machines and the selective transfer of the conveyor line are performed based on the data obtained.

[0007]

[Operation] The barcode is affixed to the appropriate location on the workpiece prior to processing. When the barcode information read by the barcode reader is input to the control device, the control device outputs program data to each processing machine and conveyor line based on the information. The passage route for each workpiece is set based on the above data, and the workpiece is introduced into only the minimum required processing machine and subjected to the required processing. The barcode reader is disposed upstream of each processing machine, and the data is checked each time, so even random transfer will not result in product defects due to processing errors.

are fed one by one to the first vertical conveyor 3 by the horizontal feed regulating means 2. The supplied workpiece W is sent to the second vertical conveyor 5 via the second horizontal conveyor 4. The barcode is then sent downstream on this conveyor, and when it reaches a predetermined position, the barcode is read by the first barcode reader 6. The dispensing and feeding means 7 is controlled by the barcode information, and the workpiece W is positioned in a clamped state. Then, the length cutting machine 8 operates to cut the front end and the rear end, and the workpiece W is set to a predetermined length. The stopper means 9a is operated to protrude onto the feed surface of the third vertical conveyor 9 based on the above barcode information. As a result, the workpiece W is transferred from the third vertical conveyor 9 to the third horizontal conveyor 10.

By the third traverse conveyor 10,

When the processing is completed, the material is sent to the fifth vertical conveyor 17 via the fifth horizontal conveyor 5 at the downstream side of the fourth vertical conveyor 12.

The workpiece W is transferred downstream on the fifth vertical conveyor 17 and its barcode is read by a third barcode reader 20 . The control data obtained from the above barcode information allows one end processing machine 1 to
8 operates, and the workpiece W, which is clamped and fixed at a predetermined position, is subjected to a required tenon process on its front end by the workpiece b. Note that the control data for the other end processing machine 23 is also extracted using the above barcode information.

will be transported to.

In the above example, the workpieces W are transferred on a serial conveyor line and processed sequentially by the side processing machine 13, the end processing machine 18 on one side, and the end processing machine 23 on the other side. However, when it is determined from the barcode information read by the first barcode reader 6 that processing of the side surface is not necessary, the stopper means 9a is retracted and the workpiece W is transferred to the downstream part of the third vertical conveyor 9. It is fed into the fourth traverse conveyor 11 at . Then, on this parallel conveyor line, the material is supplied to one of the wood finishing machines 18 by the fifth vertical conveyor 17. After this, the processing will be managed by the third barcode reader 20 at the transfer end. Note that the management contents are as detailed above.

[0020] The side surface machining of the workpiece W involves many surfaces and many machining locations, so it takes a long time. However, compared to this, wood end processing requires fewer processing points and can often be completed in a shorter time. Therefore, if the subsequent workpiece W is the latter, it can be processed in advance by using parallel conveyor lines. Note that in one embodiment, only one side processing machine 13 was provided corresponding to the fourth vertical feed conveyor 12;
A plurality of machines can be installed in series or in parallel on this conveyor 12, thereby improving processing efficiency.
