Next, a procedure for precutting the column material in the column precut equipment 1 will be described. First, processing conditions are input to a control device provided in the processing machine body 30. Then, the material W is placed on the wheel conveyor 11 and processing is started. Then, first, the taken-in material transfer body 17 is operated, and an operation of replacing one material W from the wheel conveyor 11 onto the loading conveyor 13 is performed. Thus, charging conveyor 1
When the material W is replaced on the workpiece 3, the pinch roller 31 descends and comes into contact with the upper surface of the material W, and the feeding operation is performed so that the leading end of the material W is located at the cutting position by the cross-cut saw unit 33. . Here, the optical sensor is configured to detect whether or not the leading end of the material W has reached the cutting position. When the optical sensor detects that the leading end of the material W has reached the cutting position, the feed operation by the pinch roller 31 is stopped, and the material W is clamped by the vise 39 to a centripetal state.

Subsequently, the cross-cut saw unit 33 is driven, and a cutting process of the leading end of the material W is performed. Since the remaining material generated by this cutting process is short,
By rotating the inclined roller 49 downward, it is discharged to the front side of the processing machine main body 30.

Next, the workpiece stopper unit 55 is moved to the processing origin position. Then, the clamp by the vise 39 is released, and the feeding operation by the pinch roller 31 is executed, and the material W is fed to a position where it comes into contact with a stopper provided in the work material stopper unit 55. When the leading end of the workpiece W is fed to a position where the workpiece W comes into contact with the stopper of the workpiece stopper unit 55, the workpiece W is clamped by the centripetal clamp provided on the workpiece stopper unit 55. Then, the pinch roller 31 is raised and the work material stopper unit 55 is moved to set the front end portion of the material W to a processing position by the tenon removing unit 35. Then, the clamp of the workpiece W by the workpiece stopper unit 55 is once released, and the workpiece W is fixed to the centered state by the vise 39 and the upper clamp 41. Subsequently, the tenoning unit 35 is driven in accordance with the processing conditions, thereby performing tenoning on the front end portion of the material W.

When the tenoning of the front end portion of the material W is completed, the work material stopper unit 5
5 is moved to a position where the stopper comes into contact with the front end of the material W, and the material W is clamped. Further, the clamp by the vise 39 and the upper clamp 41 is released. Then, the processing material stopper unit 55 is moved according to the processing conditions, and the predetermined position of the material W is moved to the processing position by the surface processing unit 37. Subsequently, the material W is clamped by the centripetal roller 45 and the upper pressing roller 43 in a centripetal state and movably in the axial direction. And the surface processing unit 37
So that the specified machining tool is located just below the material W,
The machining tool is moved by the servo motor 37m. By simultaneously controlling the drive of the servomotor 37m for moving the processing tool in the front-rear direction and the servomotor 37n for lifting and lowering, and also controlling the drive of the workpiece stopper unit 55, the through hole is formed in the lower surface of the material W. , Various types of processing such as horizontal insertion processing, board boring processing, and boring processing.

When the predetermined processing on one surface of the material W is completed, the clamp by the centripetal roller 45 and the upper pressing roller 43 is released, and the work material stopper unit 55 is moved toward the loading conveyor 13 so that the material W
Is moved to the position of the rollover device 47. Then, the clamping by the work material stopper unit 55 is released, and the rollover device 47 is driven to roll the material W in a state rotated by 90 degrees. When the material W is turned over in this way, the material W is clamped again by the work material stopper unit 55, and the work material stopper unit 55 is moved in accordance with the processing conditions, and the predetermined position of the material W is moved to the processing position of the surface processing unit 37. Move. Then, in the same manner as described above, while the material W is pressed by the centripetal roller 45 and the upper pressing roller 43 so as to be movable in the axial direction, necessary processing such as through-hole processing for the next surface is executed.

After the above processing has been performed on all four surfaces of the material W, the work material stopper unit 55 is again moved toward the loading conveyor 13 and the material W
To the position. Then, the clamp by the work material stopper unit 55 is released, and the rollover device 47 is released.
To rotate the material W in a state of being rotated by 90 degrees.
After the material W is turned over in this way, the material W is clamped again by the work material stopper unit 55, and the work material stopper unit 55 is moved in accordance with the processing conditions, and the predetermined position of the material W is set to the cross cut saw unit 33.
To the cutting position. Then, the material W is clamped by the vise 39 and the upper retainer 41,
The cross cut saw unit 33 is driven to cut the rear end of the material W.

After the cutting of the rear end of the material W is completed, the clamp by the vise 39 and the upper retainer 41 is released, and the rear end of the material W is moved by the work material stopper unit 55 to the processing position by the tenoning unit 35. ,
Clamping is again performed by the vise 39 and the upper retainer 41 and the like, and the mortise removal unit 35 is drive-controlled to perform mortise removal on the rear end of the material W. Thus, the predetermined processing on the material W is completed.

When the processing of the material W is completed, the clamp by the vise 39 and the upper retainer 41 is released, the work material stopper unit 55 is moved, and the processed material W is taken out and moved onto the conveyor 51.
Then, the clamp by the work material stopper unit 55 is released, and the work material push-out device 57 is driven,
The processed material W is extruded onto a receiving table 59 on which the printing device 61 is installed.

When the processed material W is extruded onto the receiving table 59, the printing device 61 is driven and controlled in accordance with the processing information, and predetermined information is written in the vicinity of the end of the processed material W. At this time, since the processed material W does not exist on the take-out conveyor 51, the processing material stopper unit 55 can be driven to start processing the next material W.

On the other hand, the length of the remaining material generated by cutting the rear end portion of the material W is detected by an optical sensor, and if the remaining material is shorter than the first reference length, an inclined roller is used. 49 is rotated downward, and is discharged to the front of the cross cut saw unit 33. On the other hand, when the length is equal to or more than the first reference length and less than the second reference length, the pinch roller 31 is driven to return the remaining material onto the feeding conveyor 13. Then, the remaining material transfer body 21 is driven to transfer the remaining material from the charging conveyor 13 onto the wheel conveyor 23, to be received by the remaining material receiving body 25, and to lower the remaining material receiving body 25 so as to be moved downward. Then, the remaining material is placed on the wheel conveyor 27 which is arranged at a downward slope. Then, the remaining material is transferred to the wheel conveyor 27.
The material slides down and is discharged below the wheel conveyor 11 for material input. If the length of the remaining material is very long, that is, the second reference length or more, the pinch roller 3
1 and the work material stopper unit 55 is driven to take out the remaining material and discharge it onto the conveyor 51. Then, similarly to the material W that has been processed, the processing material pushing device 57 is driven to push the remaining material onto the receiving table 59. It should be noted that printing is not performed on the remaining material by the printing device 61, and mortise processing and surface processing are not performed. Therefore, the operator can easily distinguish the processed material W from the remaining material and remove the remaining material on the takeout conveyor unit 50 side.

As described above, according to the column pre-cutting facility 1 of the present embodiment, in the treatment of the residual material generated by cutting both ends of the column, the residual material is always directed to the front side of the apparatus. Since it is automatically discharged, there is no need for the operator to remove the remaining material from the input conveyor one by one,
Workability can be greatly improved. In addition, the shorter ones according to the length of the remaining material are discharged to the front of the cross cut saw unit 33, the ones having a predetermined length are discharged below the wheel conveyor 11 for charging, and the ones longer than a predetermined length are discharged. Since the material is discharged forward on the side of the take-out conveyor 50, the discharge of the remaining material can be automated regardless of the length of the remaining material. In addition, since the remaining material is automatically discharged from the charging conveyor 13, the material W to be processed next can be quickly charged into the charging conveyor 13, thereby contributing to an improvement in the operation rate of the precut equipment.

Further, according to the column pre-cutting equipment 1 of the present embodiment, the printing process on the processed material W is executed in a state where the processed material W is pushed out from the take-out conveyor 51 to the receiving table 59. Therefore, the feeding and processing of the next material W can be started in parallel with this printing process. Therefore, the operation rate of the equipment can be greatly improved.

Further, according to the column material pre-cutting equipment 1 of the present embodiment, in the surface processing unit 37, one servo motor for raising and lowering the processing tool is provided although various types of processing tools are provided. The number of parts can be greatly reduced.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be embodied in various other forms without departing from the scope of the invention. it can.

For example, in the embodiment, the column pre-cutting equipment has been described, but it is needless to say that the present invention may be applied to the horizontal member pre-cutting equipment.
Further, the remaining material may be discharged by using a driven transfer means such as a chain conveyor instead of the wheel conveyor. Also, instead of detecting the length of the remaining material with an optical sensor, the length of the remaining material is calculated by calculating from the original total length of the material, and the method of discharging the remaining material is changed according to the calculation result. It does not matter. Further, when the raw material is charged from behind the pre-cut equipment, the remaining material may be sent once to the front, then lowered, and discharged under the input conveyor to the rear of the pre-cut equipment. Also,
The backward movement stroke of the residual material transfer body 21 may be long, and the residual material may be directly delivered to the residual material receiving body 25 without passing through the wheel conveyor 23.

[0041]

As described above, according to the present invention, in a wood pre-cutting facility, a long remaining material can be processed quickly and easily, thereby improving workability and reducing the operation rate of the apparatus. Can also be improved.
