Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to an automatic hammering machine for corrugated nails.

(Prior Art) Conventionally, corrugated nails are hammered into the end faces of scaffolding boards in advance to prevent cracks from drying out. However, this corrugation work was uneconomical as it required two workers to corrugate both sides of the butt sides of a fairly long scaffolding board.

(Problems to be Solved by the Invention) Therefore, the present invention eliminates the above-mentioned drawbacks and provides an automatic corrugated nail driving machine that automatically drives corrugated nails onto the end surface of scaffolding boards.

[Structure of the idea]

(Means for Solving the Problems) Hereinafter, an embodiment of this invention will be described with reference to the drawings.A conveyance path 1a on which scaffold boards A are placed on a base 1 and conveyed sequentially, A temporary fixing device 2 at one end or both ends to prevent movement of the scaffold board.
and a slide hammer 4 that uses a power source 3 such as a cylinder to drive corrugated nails B into the end surface of the scaffolding board A with its tip end surface 4a, and a large number of corrugated nails B are stacked and placed above the slide hammer. A bottomless holder 5 is provided, and between the hammer 4 and the holder 5 there is a corrugated nail B located at the bottom of the holder at the tip.
A corrugated nail sending device 6 that moves in the direction of the scaffolding board A with the corrugated nail placed thereon is fixed to the hammer 4, and a holding plate 7 for the corrugated nail is provided at the lower part of the hammer 4.

Note that a guide bar 5a and a cushion plate 5b are provided between the holder 5 and the scaffolding board A, on which the corrugated nail B sent out from the holder is mounted, so that the corrugated nail B will not be reversed or tilted, and the nail The tip is configured to appropriately abut against the end surface of the scaffolding board.

(Function) Next, to explain the function of this device, the holder 5
When the hammer 4 moves toward the end surface of the scaffold board and is pressed by the power source 3, the corrugated nail B located at the lowest position is moved by the corrugated nail sending device 6. The guide bar 5 is sent out.
Move by riding on a, and in front is a cushion plate 5b.
is provided, which prevents it from jumping forward, and it is sent smoothly and falls onto the holding plate 7 of the corrugated nail, and when the hammer 4 is next moved, it is driven into the end surface of the scaffolding board by the hammer 4. It is something that can be done.

At this time, the corrugated nail retaining plate 7, which is located at the bottom of the hammer 4 and holds the corrugated nail B to be driven, is biased by the spring 7a and protrudes from the hammer 4, but when the hammer hits the wood end surface. It's something that draws you in.

[Effect of idea]

According to this invention, the corrugated nails B are automatically driven in, and if they are provided on both sides of the scaffolding board A, it is more convenient and labor-saving, and has extremely beneficial effects.
