Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a planer for wood processing, and more particularly to a planer capable of smoothly discharging planing chips generated by cutting.

[0002]

[Prior art]

 As shown in FIGS. 5 and 6, the conventional planer has a plurality of supporting rollers 2 for supporting the lower surface of the wooden piece 1 on the base frame 3, and the supporting rollers 2 are pressed against the surface of the wooden piece 1 to rotate. By doing so, a plurality of feed rollers 4 for moving the wood at a constant speed and a planer cylinder 6 provided with 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.

As shown by the arrow in FIG. 5, the rotation direction of the planer barrel 6 is opposite to the running direction of the wood 1, and the planer blade 5 cuts in the opposite direction of the running direction of the wood 1. In some cases, as shown by the arrow in FIG. 6, the planer blade 5 cuts in the same direction as the running direction of the wood 1.

[0005]

[Problems to be solved by the device]

 As shown in Fig. 5, when the traveling direction of the wood 1 and the cutting direction of the planer blade 5 are opposite, the planer scraped by the planer blade 5 is repelled by the planer blade 5 and goes to the duct, so that the planer scrap smoothly flows into the duct. However, there is a defect that the cutting surface becomes rough because it is ground so as to be flipped up from the lower surface. As shown in Fig. 6, the one in which the planer blade 5 cuts in the same direction as the running direction of the wood 1 is cut down toward the lower surface, so the cutting surface is good, but the planer scrap is sandwiched between the pressing member 8 and the wood 1. There is a problem that it is not smoothly sucked into the upper duct 9.

An object of the present invention is to solve the above-described problems of the conventional planing board and to smoothly discharge the planing chips even if the rotation direction of the planing blade is the same as the running direction of the wood. Is to provide.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a planer that has the same cutting direction of the planer blade and the running direction of the planer, which is provided on the planer barrel having the wood pressing members at the front and rear. An air flow generating means for generating an air flow that blows up the cutting chips scraped by the planer blade is provided near the lower part of the pressing member on the side that presses the wood.

[0008]

[Action]

 When the planer cylinder is continuously rotated and the feed roller is also rotated to feed wood into the lower part of the plank, and when the wood enters below the planer cylinder, the planer blade cuts into the wood and produces planing chips. This planing dust is sucked upward by the air flow blowing out below the planing dust from the air flow generating means. The planed chips scraped off in this way are sucked into the duct and smoothly discharged.

[0009]

【Example】

 In the embodiment shown in FIGS. 1 and 2, a base frame 11 has a plurality of supporting rollers 12 rotatably mounted thereon. 13 is a feed roller on the rear side, that is, on the entrance side of the lumber, and 14 is a driving motor for driving the feed roller 13 by the motor 14 via a transmission belt 15.

Further, the feed roller 13 is pressed against the upper surface of the wood 19 as the object to be cut on the support roller 12 by an appropriate pressurizing means 17 such as an air cylinder.

Reference numeral 20 denotes a planer barrel having a plurality of planer blades 21 fixed to the outer periphery. The planer cylinder 20 rotates at a fixed position, and the mounting position of the bearing is changed only when the thickness of the wood 19 is changed and when the cutting depth is changed.

Reference numeral 22 is a drive motor for the planer barrel 20, which drives the planer barrel 20 in the direction of the arrow by the transmission belt 23. In addition, pressing members 24 and 25 that press the upper surface of the wood 19 to prevent it from jumping up are arranged on the front and rear sides of the planer body 20.

Numeral 26 is a feed roller on the exit side, which is pressed against the wood piece 19 by pressing means 27 such as an air cylinder like the feed roller 13. Further, the feed roller 26 is interlocked with the feed roller 13 by a transmission belt 29 to rotate both feed rollers 13 and 26 at the same peripheral speed in the arrow direction.

An exhaust duct 30 is provided above the planer body 20, and the duct 30 is connected to an exhaust fan (not shown). In addition, a side plate 31 covers between both sides of the front and rear pressing members 24 and 25.

Reference numeral 32 is a plurality of grooves provided as an example of the air flow generating means provided in the lower portion of the holding member 24 on the outlet side. In the case of the embodiment shown in FIGS. 3 and 4, an air supply passage 33 is provided which extends from one example of the lower end of the member 24 to the other side, and a large number of nozzles 34 are provided on the plane side of the member 24 near the lower end.

An air supply pipe 35 is connected to the open end of the air supply passage 33, and this pipe 35 is connected to a compressed air source not shown in the drawing.

In the embodiment shown in FIGS. 1 and 2, the motor 14 drives the feed rollers 13 and 26 so that the motor 22 moves the planer cylinder 20 in the same direction as the feed rollers 13 and 26 and the feed rollers 13 and 26. Drive at a faster speed.

When the wood 19 to be cut is fed from the right side of FIG. 1 onto the base frame 11 while the feed rollers 13 and 26 and the planer cylinder 20 are driven as described above, the wood 19 is supported by the feed roller 13. It moves while being pressed onto the roller 12.

When the cutting of the wood 19 starts as described above, the exhaust fan connected to the exhaust duct 30 also starts operating, so that a negative pressure is generated between the front and rear pressing members 24 and 25.

Therefore, the outside air blows into the lower portion of the pressing member 24 from each groove 32, and this air flow blows up the planks upward and guides them to the duct 30.

In the embodiment shown in FIGS. 3 and 4, the air between the pressing members 24 and 25 is sucked by the exhaust duct 30, and the compressed air is blown from each nozzle 34 toward the lower side of the planer barrel 20.

Therefore, the planer chips generated by cutting are quickly blown up and sucked into the duct 30.

[0023]

【effect】

 In this invention, the running direction of the wood and the cutting direction of the planer blade provided on the planer cylinder are the same as described above, the wood pressing members are arranged in front of and behind the planer cylinder, and the exhaust gas is provided above the planer cylinder. In a planer where a duct is provided so that the planks are sucked into the duct by the air flow, an air flow generating means is provided near the lower end of the pressing member on the exit side of the wood to blow up the planks. It is discharged smoothly.

Therefore, even if the traveling direction of the wood and the cutting direction of the wood are the same, the discharge of the planks will not be hindered, and a beautiful and accurate cutting surface can be obtained.
