Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an assembly device for a barre and throat which is integrated by nailing and fixing plate pieces from both sides with a girder in between. be.

[Prior art]

This kind of palette is shown in Figure 5F! 1), fbl, t
As shown in c+, a plurality of girder members 1 having a thickness set corresponding to the thickness dimension of the fork of a forklift are arranged in parallel, and each of the girder members 1 is arranged in a right angle direction on both sides of these girder members 1, A plurality of plate pieces 2 fixed to the girder 1 by nailing. ...and 3. It is composed of...

Conventionally, as a device for assembling the above-mentioned pallets, for example, Japanese Utility Model Publication No. 48-6398 and Japanese Utility Model Application Publication No. 62-32737 have been used.
The one disclosed in the publication No. 1 is known.

In the assembly device disclosed in the above-mentioned Japanese Utility Model Publication No. 48-6398, a plurality of girders and a plate piece on one side are placed on the upper surface of a traveling truck, and after the traveling truck is moved to a location where a nailing machine is installed. The plate piece on one side is nailed to the girder material using the above-mentioned nailing machine and fixed. Thereafter, the traveling truck is returned to its original position, and the girder and the single-sided plate are lifted from the top of the truck and turned over, and then placed on the top of the truck again. Then ζ, a plate piece is placed on the other side of the plate material,
It is moved again to the installation location of the nailer, and the plate piece on the other side is nailed to the girder material by the nailer and fixed.

On the other hand, in the assembly apparatus disclosed in Japanese Utility Model Application Publication No. 62-32737, the first. a second assembly nailing device; and the first assembly nailing device. It is disposed between the second assembly nailing devices and includes a ball B and a workpiece pedestal provided with a figure-7 groove for inverting the material in an inclined state.

In the first assembly nailing device, after the plate pieces are nailed and fixed on one side of the girder material, the tip portion of the pallet material consisting of the girder material and the plate pieces on one side is attached to the workpiece receiver. It is accommodated in the groove of the stand.

Then, after the bullet material No. 2 is inverted in an inclined state, it is supplied to the second assembly nailing device, and a plate piece is nailed to the other side of the girder material of the bullet material and fixed.

(Problem to be Solved by the Invention) However, in the assembly apparatus disclosed in the above-mentioned Japanese Utility Model Publication No. 48-6398, when nailing a plate piece to the other side of the girder material, the bullet material must be lifted and turned over. Also,
There is a problem in that the plate pieces cannot be placed on the other side of the finger material until after the above-mentioned bullet material has been turned over, resulting in poor work efficiency during pallet assembly work.

Moreover, the assembly apparatus disclosed in the above-mentioned Japanese Utility Model Publication No. 62-32737 must be equipped with a dedicated workpiece pedestal for inverting the bullet material, and a relatively large work space is required. Furthermore, when nailing a plate piece to the other side of the girder material, the sound of the work is reduced because the bullet material has to be turned over each time using the workpiece holder, which poses the problem of poor work efficiency. .

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pallet assembly device that can efficiently and quickly nail plate pieces to beams made of barene materials in a small work space.

[Means to solve the problem]

In order to achieve the above object, the main means adopted by the present invention is assembling a pallet that is integrated by nailing and fixing board pieces from both sides with girders in between. In the apparatus, a holding means for holding the bullet material consisting of the girder material and the plate pieces applied from both sides of the girder material in an assembled state of a pallet, and plates on both sides of the bullet material held by the holding means. This bullet assembling device comprises a reversing means for rotating the holding means and reversing the front and back of the bullet material so that the pieces can be nailed and fixed to the girder material one after another.

[Effect]

- After the plate pieces on one side of the bullet material held in the assembled state of the pallet by the holding means in F are nailed to the girders and fixed, the holding means in F is rotated in that position by the reversing means. - The pallet material is turned over. Thereafter, a plate piece is nailed to the other side of the beam member and fixed.
