DETAILED DESCRIPTION OF THE INVENTION “Industrial field of application” The present invention relates to a woodworking plane machine suitable for cutting both sides of wood, and particularly, to a long plate material on a workbench.
The present invention relates to a woodworking plane board device configured to pass between a pair of upper and lower rotary cutter heads while feeding along the longitudinal direction and scrape both upper and lower surfaces of a plate material by these rotary cutter heads.

"Prior Art" Conventionally, in a wood-based prefabricated house or the like, a means for constructing walls, floors, roofs, and the like by so-called wood panels made of plywood or the like has been implemented.

A wooden panel applied to the construction of such a prefabricated house is, for example, a frame material (core material) that constitutes a vertical frame and a horizontal frame.
By arranging the reinforcing members extending vertically and horizontally inside the frame that is assembled in a square frame shape, and further filling the inside surrounded by these reinforcing members and the vertical and horizontal frames with a heat insulating material such as glass wool. In addition, a face material made of plywood is attached to both front and back surfaces of the frame body.

By the way, in the conventional manufacturing method of this type of wood panel, when manufacturing the panel, a means for finishing the wood surface by shaving wood constituting the panel with a plane is carried out as a pre-process. Such a pre-process has hitherto been performed by using a woodworking plane device as shown in FIG. 4, for example.

That is, this woodworking plane device feeds a long piece of wood W along its longitudinal direction while passing it between a pair of upper and lower rotary cutter heads 1a, 1b, and by these rotary cutter heads 1a, 1b. The upper and lower surfaces of the plate material W are scraped, and specifically, a work table 2 on which wood is placed, and a feed roller 3a which is set on the work table 2 and sends the plate material W toward the rotary cutter heads 1a, 1b. It is mainly composed of a first holding frame 4 provided and a second holding frame 5 which is set on the work table 2 and holds the upper rotary cutter head 1a.

The workbench 2 is provided with a lower rotary cutter head 1b, and at the position facing the insertion port 2a of the plate material W, the lower surface of the plate material W is rolled and the plate material W is rotated by the rotary cutter heads 1a, 1b. A feed roller 3b is provided for feeding toward the.

On the other hand, the first and second holding frames 4 and 5, respectively,
The support frame part 2b is provided on the support frame part 2b provided on the upper surface of the workbench 2.
It is supported movably up and down through screw type setting handles 6 and 7 that penetrate through the upper part of the above, and a pair of front and rear feed rollers 3a is supported on the first holding frame 4 via a rotary shaft. Has been done.

The second holding frame 5 is provided with a pressing roller 8 for pressing the plate material W from above together with the upper rotary cutter head 1a, and the second holding frame 5 is locked by the lock mechanism 9 so that its position can be improved. Are to be positioned.

Then, in order to grind both sides of the plate material W with the woodworking plane device having such a configuration, first, the setting handles 6 and 7 are turned to a rotary cutter head having a height dimension corresponding to the thickness of the plate material W. Adjusting 1a and feed roller 3a, lock mechanism 9
The holding frame 5 is positioned by, then the plate material W is inserted from the insertion port 2a of the workbench 2 and is fed between the rotary cutter heads 1a and 1b by the feed rollers 3a and 3b, and the rotary cutter heads 1a and 1b are fed. The upper and lower surfaces of the plate material W are finished by passing the space between them.

"Problems to be Solved by the Invention" The present invention is intended to solve the following problems in the above-described conventional art.

First, in the woodworking plane device as shown in FIG. 4, in order to adjust the height dimensions of the feed roller 3a and the upper rotary cutter head 1a, the setting handles 6 and 7 must be manually turned. In particular, since the threaded portions of the setting handles 6 and 7 have relatively large threads, it is difficult to finely adjust, and there is a problem that there are many errors in the initial dimension setting.

Moreover, since there are so many types of panels, wood, etc. used for homes, it is the actual situation that the adjustment work is often done.The development of a woodworking board device that supports so-called high-mix low-volume production Is desired.

Secondly, if the adjustment operation is to be automated by numerical control, the control becomes complicated and the cost becomes high.

The present invention has been proposed in view of the above-mentioned circumstances, and an object thereof is to make it possible to set the dimensions of a rotary cutter head, a feed roller, etc. at one time, and to automate the dimension setting. It is to provide a woodworking board device capable of achieving high-mix low-volume production.

"Means for Solving the Problem" In order to achieve such an object, the present invention is to feed a long plate material on a workbench along a longitudinal direction thereof while moving between a pair of upper and lower rotary cutter heads. In a woodworking board machine that cuts both the upper and lower sides of a plate with these rotary cutter heads, it is held by an actuator so that it can move in the vertical direction, and the upper surface of the plate rolls to feed the plate toward the cutter head. A first holding frame including: a second holding frame that is held by an actuator so as to be movable in the vertical direction and includes an upper rotary cutter head; and the work table and the first and second holding frames. It is characterized by comprising a plurality of types of adjustment spacers, which are respectively interposed between the spacers and adjust the height position of the holding frame.

Further, in the above, if an extruding mechanism for extruding the plate material past the rotary cutter head is provided at a position in front of the feed roller of the workbench, the end of the plate material can be reliably delivered to the rotary cutter head. Therefore, it is preferable when the plate material is fully automated.

[Operation] According to the woodworking board device of claim 1, the first and second holding frames are pushed up by the operation of the actuator, and a spacer for height adjustment is provided between these holding frames and the workbench. After interposing, the actuator is actuated to lower the first and second holding frames,
It is possible to position these holding frames reliably and quickly at a position according to the height of the adjustment spacer.

Then, even during the operation of the woodworking board device, the first and second holding frames are pressed against the adjusting spacers by the actuators, whereby the feed roller and the upper rotary cutter head provided in the holding frame are respectively pressed. It can be fixed.

When changing the height of the feed roller and upper rotary cutter head, operate the actuator to raise the holding frame, and adjust the spacers according to the height to be changed between the holding frame and the workbench. It is sufficient to replace the holding frame with the adjustment frame by moving the holding frame to the adjustment spacer.
