Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a planer having a fixed planer blade.

[0002]

[Prior art]

 As shown in FIG. 3, the conventional planer has a plurality of support rollers 2 for supporting the lower surface of the wood 1 to be cut on the base frame 3, and the support rollers 2 are pressed onto the surface of the wood 1. A plurality of feed rollers 4 that rotate the wood to run at a constant speed, and a planer cylinder 6 having a plurality of planer blades 5 on the outer circumference are provided.

Pressing members 7 and 8 are provided in front of and behind the planer body 6, and an exhaust duct 9 is provided above the planer body 6 so that planer dust generated by cutting is sucked by the duct 9.

Further, the feed roller 4 is driven by a motor 10 in the arrow direction via transmission belts 11 and 12, and the planer barrel 6 is driven by a motor 13 in the arrow direction via a transmission belt 14. Further, each of the feed rollers 4 is pressed against the wooden piece 1 by a pressing means 15 such as an air cylinder.

[0005]

[Problems to be solved by the device]

 In the planer using the conventional rotary planer barrel 6 as described above, the planer blade 5 cuts the traveling wood 1 while rotating at high speed, so that the cutting surface becomes uneven. Further, there arises a problem that the cutting thicknesses are slightly different. In order to solve the above-mentioned problems, an object of the present invention is to provide a planer board that can obtain a highly precise finished surface by a fixed planer blade.

[0006]

[Means for Solving the Problems] In order to solve the above problems, the present invention is directed to a receiving plate for receiving a piece of wood to be cut, supporting rollers provided in front of and behind the receiving plate, and arranged on the supporting rollers, respectively. A configuration was adopted that consisted of a vertical feed roller, a fixed planer blade provided above the backing plate, and a pressing member that presses the wood to be cut onto the backing plate immediately before this planer blade.

[0007]

[Action]

 This invention has the above-mentioned configuration, and the wood to be cut is inserted between the support roller and the feed roller on the inlet side, and the wood is fed between the receiving plate and the pressing member by the rotation of the feed roller.

The fed wood is sandwiched between the receiving plate and the pressing member and moved while being cut by the fixed planer blade, sandwiched between the support roller and the feed roller on the outlet side and pulled out.

[0009]

【Example】

 In the embodiment shown in FIGS. 1 and 2, reference numeral 21 is a receiving plate for receiving the wood 20 to be cut, which is fixed on the base frame 22. Further, rotatable support rollers 23 are arranged in front of and behind the receiving plate 21, respectively.

Reference numeral 24 in FIG. 2 denotes a rear frame, on which an upper frame 25 is provided. Reference numeral 26 denotes a movable frame that is vertically moved along a pair of left and right guide rails 27 provided on the front surface of the upper frame 25, and can be set to an arbitrary upper and lower position by a vertical feed screw 30 that is normally and reversely rotated by a motor 29. .

Further, the movable frame 26 is hollow, the lower part thereof is open, and the feed rollers 31 located directly above the respective support rollers 23 are provided inside the movable frame 26, but the feed rollers 31 are not shown. It is driven at the same peripheral speed in the arrow direction of FIG. 1 by the driving means.

Further, each feed roller 31 has a function of pressing the wooden piece 20 onto the supporting roller 23 by a pressing means 32 such as an air cylinder provided on the movable frame 26 to move the wooden piece 20.

Reference numeral 33 in FIG. 1 denotes a bracket fixed to the inside of the center of the movable frame 26, and a fixed planer blade 34 is fixed to the bracket 33. If necessary, a back blade 35 for preventing an inversion is fixed to the planer blade 34 with a bolt or the like.

A pressing member 36 is provided immediately in front of the planer blade 34, and this member 36 is also pressed downward by a pressing means 37 such as an air cylinder provided on the movable frame 26 like the feed rollers 31. Is pressed.

Next, the operation of the above embodiment will be described.

First, the feed screw 30 is driven by the motor 29 to position the movable frame 26, and the cutting thickness, that is, the distance between the upper surface of the receiving plate 21 and the planer blade 34 is set.

Next, the feed roller 31 is driven to insert the wood 20 to be cut into the entrance side, that is, between the support roller 23 and the feed roller 31 on the right side of FIG. 1, and the feed roller 31 rotates. The wood 20 is fed between the receiving plate 21 and the pressing member 36.

The fed wood 20 is sandwiched between the receiving plate 21 and the pressing member 36, and is cut by the fixed planer blade 34 while moving, and at this time, the back blade 35 and the pressing member 36 prevent an adverse effect. . The wood 20 cut in this way is sandwiched between the support roller 23 and the feed roller 31 on the exit side and is pulled out.

[0019]

【effect】

 Since this invention cuts the surface of the wood with the fixed planer blade as described above, there is no risk of the cutting surface becoming wavy like the conventional rotary planer blade, and the backing plate and the fixed planer blade. Since the cutting thickness is regulated by, it can be finished to an accurate thickness. Therefore, it is most suitable for finishing wood.
