BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic multi-sided woodworking planer provided with a work piece such as a plate or a square piece, a so-called longitudinal side surface of a work piece, and a vertical axis cutter column for cutting a so-called cod.

[0002]

2. Description of the Related Art A planer, which is one of the representative woodworking machines,
There are various types of so-called woodworking planar cutter shafts having one to four axes, and the types thereof are classified into a manual type and an automatic type.
Of these, an automatic multi-sided woodworking planer equipped with a vertical cutter column is a suitable facility for large-scale processing and is often used because it performs simultaneous cutting on three to four sides including the work piece. .

[0003]

However, the conventional planer for automatic multi-faced woodworking has problems that it takes time to change the setup due to the change of the working dimension, and that adjustment requires skill. That is, when the width of the work is largely changed, naturally, the vertical axis cutter column also needs to be correspondingly moved for a long distance. This relocation takes time,
Adjustment is also difficult. To release the vertical axis cutter column from the slide rail and move the vertical axis cutter column by several tens of millimeters or more, the square screw spindle provided for this moving operation must be rotated a lot, and usually it must be manually turned. It is tedious and time consuming. Further, this square screw spindle has a backlash, and an error occurs when it is fixed unless the rotation direction when stopping is specified. Therefore, in order to accurately fix the vertical cutter column, it may be necessary to repeat the process of performing test cutting, checking the working dimensions and re-adjusting, and omitting this requires a high degree of skill. . It is an object of the present invention to provide an automatic multi-faced woodworking planer capable of easily and accurately changing the position of the vertical cutter column.

[0004]

SUMMARY OF THE INVENTION In an automatic multifaceted woodworking planar of the present invention, a vertical axis cutter slidably mounted on a slide rail arranged in a direction orthogonal to the work traveling direction. A positioning device for determining a position of the vertical cutter column in the direction along the slide rail is connected to the vertical cutter column, and the positioning device includes a spindle connected to the vertical cutter column. A double-acting cylinder having a stroke adjusting mechanism for adjusting the stroke of the spindle, and the stroke adjusting mechanism has a holding member attached to the spindle and a plurality of portions having different widths. A staircase-like insertion plate that is formed and has one of a plurality of portions having different widths clamped between the cylinder and the clamp member; A stepwise insertion plate moving mechanism that is connected to the insertion plate and moves the stepwise insertion plate so as to determine the portion of the stepwise insertion plate that is clamped between the cylinder and the clamping member. The fact that it is configured is taken as a means for solving the above problems.

[0005]

According to the automatic multi-sided woodworking planer of the present invention,
Since the position of the vertical axis cutter column is determined by the positioning device including the stroke adjusting mechanism including the sandwiching member, the step insertion plate, and the step insertion plate moving mechanism,
By determining the position of the vertical axis cutter column by adjusting the stroke of the spindle by the stroke adjusting mechanism, it becomes possible to change the position of the vertical axis cutter column in accordance with the change in the working width of the work quickly and accurately.
Further, the position of the vertical cut column that determines the machining width of the work is adjusted by the stroke adjusting mechanism connected to the spindle of the double-acting cylinder. Since it is a simple mechanism that holds one of different parts between the cylinder and the holding member, it is possible to easily check the cause and the like even when a trouble such as a failure occurs. Further, since the stroke adjusting mechanism is a mechanical mechanism,
For example, the stroke accuracy of the spindle, that is, the positional accuracy of the vertical cutter column can be maintained higher than that of an electrical mechanism.

In the figure, 1 is a planer for automatic multifaceted woodworking, 2 is a work, 3 is a fixed vertical axis cutter column, 31 is a fixed vertical axis cutter column 3 cutter,
Reference numeral 4 denotes a vertical axis cutter column on the moving side, which will be simply referred to as a vertical axis cutter column hereinafter. 41 is a cutter of the vertical axis cutter column 4. 42 is a slide rail for mounting the vertical cutter column 4, 5 is a cylinder, 51 is a spindle of the cylinder 5, 6 is a stroke adjusting mechanism attached to the spindle 5,
Reference numeral 7 is a positioning device for the vertical cutter column 4.

An automatic multi-sided woodworking planar 1 shown in FIG.
Is an automatic four-sided woodworking planer for automatically cutting both upper and lower surfaces of the work 2 and left and right side surfaces, so-called cobs, but the cutter heads for the upper and lower surfaces are not shown. One of the vertical axis cutter columns for cutting the left and right flanks of the work 2 is the fixed side vertical axis cutter column 3, and the other is the movable side vertical axis cutter column 4, which will be described below. This is simply called the vertical cutter column 4. A cutter 31 and a cutter 41 are attached to each of these. The vertical axis cutter column 4 is mounted on a slide rail 42 arranged orthogonal to the traveling direction of the work 2 so as to be slidable along the slide rail 42. A spindle 51 of a double-acting cylinder 5 attached to the side of the slide rail 42 is connected to the vertical cutter column 4. In this embodiment, the cylinder 5 is an air-driven type, but it goes without saying that it may be a hydraulic cylinder.

The spindle 51 of the cylinder 5 is of a form projecting to the front and rear of the cylinder. One is connected to the vertical cutter column 4 and the other is the stroke adjusting mechanism 6.
Are connected and arranged. As shown in FIG. 2, the stroke adjusting mechanism 6 includes a step-like insertion plate 61 having a plurality of steps, that is, having a plurality of portions having different widths. The spindle 51 has a mechanism for sandwiching it and the adjusting screw 52 for fine adjustment and a bush 53 which serves as a sandwiching member in the present invention. And
With such a configuration, the stroke adjusting mechanism 6 adjusts the stroke amount of the spindle 51 by changing the position of the stepped portion (portion having a different width) to be sandwiched by the stepped insertion plate 61. This stroke adjustment is performed so as to regulate the movement of the workpiece 2 approaching the width center thereof as shown in the drawing. That is, the vertical axis cutter column 4 is closer to the width center than the position regulated here.
Is not movable and the processing width of the work 2 is prevented from being narrowed further. As a result, even if the air pressure on the cylinder 5 is reduced, the cutter 41 of the vertical cutter column 4 does not get into the dent of the workpiece 2.

In the stroke adjusting mechanism 6, the stepped insertion plate 61 is moved so as to change the position of the stepped portion (portion having a different width) to be held by the stepped insertion plate 61. A mechanism is provided. In this embodiment, this step-like insertion plate moving mechanism has a step-like insertion plate 6
A thin roller chain 62 connected to one end of the automatic multi-faced woodworking planar 1 and extending to near the operation panel of the planar machine 1 for automatic multifaceted woodworking; and an operation connected to the roller chain 62 and disposed near the operation panel The operation lever 63 is operated to change the insertion position of the staircase insertion plate 61 via the roller chain 62 by remote control. In this embodiment, an air valve 64 is attached to the operation lever 63, the hose 65 is connected to the cylinder 5 from the air valve 64, and the cylinder 5 is operated at the same time as the operation lever 63 is operated. It is designed to be operated remotely.

The above cylinder 5 and its spindle 51,
The stroke adjusting mechanism 6 having the stepwise insertion plate 61 constitutes a positioning device 7 for the vertical cutter column 4. To change the position of the vertical cutter column 4, the fixing screw of the vertical cutter column 4 to the slide rail 42 is loosened, the air valve 64 of the positioning device 7 is operated, and the cylinder 5 is released. Next, the operating lever 63 is rotated to move the stepped insertion plate 61 up and down, and the insertion depth is set so that the step portion corresponding to the position of the vertical cutter column 4 corresponding to the changed machining width of the work 2 is clamped. Decide. When the stepped insertion plate 61 reaches a predetermined insertion depth, the operation lever 63 is stopped and the air valve 64 is operated to supply air to the cylinder 5. Then, the spindle 51 moves and the vertical axis cutter column 4 moves. This movement is performed by the spindle 5
When the staircase insertion plate 61 is sandwiched between the bush 53 attached to No. 1 and the end plate of the cylinder 5, it stops. If the vertical cutter column 4 in this state is fixed to the slide rail 42 with a fixing screw, the movement is completed.

The vertical cutter column 4 is moved directly by the spindle 51 of the cylinder 5, which is extremely quick. Even at the stop position, the pressing force of the spindle 51 acts on the stroke regulation by the staircase insertion plate 61, so that there is no backlash, and the tightening and fixing by the fixing screw in this state is performed very accurately. If each step of the staircase insertion plate 61 is formed so as to match the expected working width, the vertical cutter column 4 can be moved in a short time of about several seconds for any working width. There is little front and rear work, and the loosening and tightening of the fixing screw between the vertical cutter column 4 and the slide rail 42 and the operation of the operating lever 63 and the air valve 64 are sufficient.

The automatic multi-sided woodworking planer of the present invention can be modified in various ways other than the above embodiment. For example, the stepped insertion plate moving mechanism in the stroke adjusting mechanism may be replaced with the roller chain and the operating lever, and may be an electric means including a pulse motor and a select switch including forward / reverse switching.

[0013]

The automatic multi-sided woodworking planer according to the present invention determines the position of the vertical cutter column by the positioning device having the stroke adjusting mechanism. The accompanying change in the position of the vertical cutter column can be performed extremely quickly and accurately. Further, the position of the vertical cut column that determines the machining width of the work is adjusted by the stroke adjusting mechanism connected to the spindle of the double-acting cylinder. Since it is a simple mechanism that holds one of the different parts between the cylinder and the holding member, even if a trouble such as a failure occurs, you can easily check the cause etc.
Maintenance and inspection can be performed easily. Further, since the stroke adjusting mechanism is a mechanical mechanism, it is possible to maintain the stroke accuracy of the spindle, that is, the positional accuracy of the vertical cutter column, higher than that of an electric mechanism, and thereby, it is possible to cut the workpiece. The dimensional accuracy can be increased.
