As shown in FIGS. 1 and 2, the butt end (end surface in the longitudinal direction) and the butt surface (side surface in the lateral direction) require various types of processing, as shown in FIGS.

Incidentally, Fig. 1 a to i show various processing states on the workpiece W, Fig. 1 a and b show mortise processing 1 and 2, and Fig. 1 c shows peripheral bevel processing 3 and 1

Further, FIGS. 2a to 2d show an example of the state in which the above-mentioned various processes have been performed on the tube column 12 and the through column 13.

Conventionally, in order to perform the above-mentioned various types of processing on workpieces, each single-function machine was used, so firstly, a number of processing machines corresponding to the types of processing were required, and therefore a large number of workers were required. Second, since a large number of various processing machines are connected by a conveyor, a large installation space is required, which also increases the distance that the workpiece must be moved, reducing work efficiency.
Third, since each type of machining is performed separately, it is necessary to mark each machining position, which requires extra manpower.Fourth, the workpiece is repeatedly clamped and unclamped each time machining, which reduces machining accuracy. There were drawbacks such as things getting worse.

(Problems to be Solved by the Invention) The present invention makes it possible to clamp the workpiece at any location and move it by any width in the left-right direction, as well as roll the workpiece on its side. To provide a pillar processing machine for wooden constructions that can automatically perform various processing operations on workpieces as shown in FIG. The purpose is to

(Means for Solving the Problems) A column processing machine for wooden construction according to the present invention is installed between a processing material input conveyor and a processing material take-out conveyor, and is characterized by comprising the following units.

(b) A cut-off stopper that is controlled to enter and retreat from any direction into a predetermined part of the movement path of the workpiece being taken out from the input conveyor and moved toward the take-out conveyor, and a cut-off stopper that is held at a position directly above the cut-off stopper so that it can be raised and lowered in a controllable manner. A cutting unit consisting of a rotary cutter that cuts the workpiece in the transverse direction.

(b) The lower part of the workpiece is controlled to move up and down, and at its top dead center, the workpiece is placed on the top, and the workpiece is overturned by the action of the rod of the cylinder that advances and retreats from the width direction of the workpiece, At the bottom dead center, the rolling unit is in a standby state below the workpiece.

(c) A centripetal vise consisting of a centripetal roller that comes into contact with the workpiece from both sides in the transverse direction and a centripetal vise that clamps the workpiece that has been moved to a predetermined position;
roller unit.

(d) A plurality of types of cutters connected to a drive source are attached to one or more elevating bodies that move up and down in the vertical direction guided by guide bodies installed upright on a base that is controlled to move laterally on both sides of the workpiece. A cutter unit consisting of

(e) At least one conveyor unit is disposed on the input conveyor and has a drive roller that is controlled to move up and down above the workpiece so that it can come into contact with the upper surface of the workpiece.

(f) A positioning unit that is controlled to move along a rail parallel to the take-out conveyor and has a stopper that is controlled to move forward or backward onto the path of the workpiece from any direction, and a vice that clamps the workpiece.

(Function) Taking the pipe column 12 shown in FIGS. 2a and 2b as an example, and explaining its processing, first, the processed material W shown in FIG.
When the workpiece W is placed on the input conveyor with the α surface 14 of , the leading end surface of the workpiece W in the traveling direction comes into contact with the edge cutting stopper of the cutting unit that has entered the movement path of the workpiece W in advance, and the workpiece W is stopped.

In this state, the centripetal vise and the centripetal vise of the roller unit clamp and fix the workpiece W, and the rotary cutter of the cutting unit descends to cut the tip of the workpiece W to a slight width in the longitudinal direction. After cross-cutting and adjusting the shape of the tip of the workpiece W, it is unclamped.

Next, the drive roller rotates again and the workpiece W
is further conveyed toward the tip. At this time, the processed material W
The workpiece W is conveyed by lowering the drive rollers of other conveyance units which are optionally provided depending on the length of the workpiece W.

Then, the workpiece W comes into contact with a stopper of a positioning unit that has entered a predetermined position on the path and stops at the original position. The origin position is a position where, when performing multiple types of processing on the workpiece W, a specific type of cutter that is scheduled to be processed first in consideration of its processing efficiency is placed at the planned processing position of the workpiece W. Say the position of the workpiece W such that it will be different,
In the embodiment described later, this is the position where the tip tenon cutter approaches the left end of the workpiece W.

In this state, the centripetal vise clamps the workpiece W, and the later-described tenon cutter performs tenoning on the tip of the workpiece W while being controlled to move laterally on both sides of the workpiece W and in the vertical direction. Let's do it.

Thereafter, the centripetal vise of the roller unit unclamps, and the vice of the positioning unit clamps the tip of the workpiece W, and the positioning unit moves the workpiece by a predetermined width in the forward direction or backward direction according to the order of scheduled machining. Each time, the cutter in the scheduled order close to the scheduled processing position performs the scheduled processing 2 to 11 while being controlled to move both sides of the workpiece W in the lateral direction or in the vertical direction.

During this machining, the rollover unit moves up at the necessary timing as needed, places the workpiece W in an unclamped state on the top, and rolls it over so that the β surface 15 shown in FIG. 2b is After lowering it, the rollover unit lowers again.
Since the workpiece W usually has a square cross section, the above-mentioned overturning angle is usually 90°.

When performing mortise processing on the rear end of the workpiece W, the workpiece W is positioned so that the rear end of the planned entire length of the workpiece W is located directly below the cutter of the cutting unit. After the unit clamps, moves and positions the workpiece W, and cuts the entire length of the workpiece W with the cutter, the workpiece W is moved to a position where its rear end approaches the rear end tenon cutter. Then, tenon processing 1 is performed on the rear end.

The remaining material separated during the full-length cutting described above is pushed by the end cutting stopper that is moved in the backward direction by the remaining material removal cylinder, and falls downward through the gap set between the processing machine and the input conveyor.
