Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding roller supporting mechanism for a right-angled two-sided planer having a feeding device.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIGS. In a right-angled two-sided planer in which a material is fed by a material feeding device 16, a roller shaft 29a protruding from one end of a material feeding roller 29 is cantilevered by bearings 30 and 31,
The roller shaft 29a and the bearings 30 and 31 are supported in the arm 37, and the arm 37 is provided with the material feeding rollers 29 and 2 of the material feeding device 16.
A swing shaft 35 provided between the shafts 9 is swingably supported, and springs 32 and 33 are provided above the arm 37, respectively. The cantilever structure of the material-sending roller 29 can reduce the distance L (FIG. 5) between the end surface of the material-sending roller 29 and the guides 10 and 11, so that the material-sending roller 29 can handle even a narrow processed material. It is possible to send materials.

In the case of the cantilever structure, the movement of the material-feeding roller 29 when pressing the work material is as shown by the arrow in FIG. 4, in contrast to the vertical movement of the both-end-supporting structure in which both ends of the material-feeding roller are supported by bearings. It will oscillate. When the roller shaft 29a swings, the power transmission chain or belt is not directly hung between the roller shafts 29a, but the chain 34 is once hung between the swing shafts 35, and then the swing shaft 35 and the roller shafts 29a are connected. It was a transmission mechanism connected by a chain 36.

[0004]

Conventional material feeding roller 29
Since the supporting mechanism of (1) has a cantilever structure, the material feeding roller 29 (including the bearing portion) becomes long, so the width of the material feeding device 16 (W2).
Grows larger. Further, since the material feeding roller 29 is of a swing type, the arm 37 for supporting the roller shaft 29a is required. Further, since the power transmission member for driving the material feeding roller 29 cannot be directly connected between the roller shafts 29a and is transmitted via the swing shaft 35, there is a problem that the transmission member becomes complicated.

An object of the present invention is to make the distance between the guide and the end surface of the material feeding roller almost the same as that of the conventional cantilever structure,
To reduce the size of the material feeding device and simplify the power transmission mechanism.

[0006]

The above object is to mount a horizontal planing cylinder having horizontal planing blades on a base, and dispose a front table and a rear table in front of and behind the horizontal planing cylinder, and to rear the horizontal planing cylinder. A vertical planer cylinder having vertical planer blades is erected at a right angle on the rear table surface, front and rear guides are provided in front of and behind the vertical planer cylinder, and the feeding device is vertically moved facing the table surface. In a freely arranged two-sided planer, a material feeding motor and a material feeding roller driven by the material feeding device are arranged in the material feeding device, bearings are provided on both sides of the material feeding roller, and a bearing on the guide side is provided. This is achieved by embedding it in the roller.

[0007]

With the above-described structure, the distance between the end surface of the material feeding roller and the guide is cantilevered, and the material feeding roller can be shortened by supporting both ends so that the width of the material feeding device can be reduced. Can be made smaller.

A material feeding device 16 is provided at the upper end of the column 15. A plurality of material feeding rollers 17, 17 ... (Four in this embodiment) and a material feeding roller driving motor 18 for driving the plurality of material feeding rollers 17 are provided inside the material feeding device 16, and a chain 19 feeds the material feeding rollers. 17 and a feeding roller driving motor 1
And 8 are connected. The lower end of the column 15 has a lifting screw 20.
The column 15 moves up and down together with the material feeding device 16 by using the column holder 14 as a guide by rotating the elevating screw 20 with the material feeding device lifting motor 21 provided inside the base 1.

In FIG. 3, a material feeding roller 17 includes a roller portion 17a for feeding a processed material and roller shafts 17b, 17 at both ends.
It consists of c. The roller shafts 17b and 17c are supported by bearings 22 and 23, so that the roller 17 is supported on both sides. The roller shaft 17b on the side of the guides 10 and 11 is embedded in the roller 17a and is supported by the bearing 22. The bearing 22 supports the roller 17a in a crowned state, and slightly protrudes from the right end surface of the roller portion 17a. Springs 24 and 25 are provided above the bearings 22 and 23, respectively.

It is possible to move up and down in 6.

A sprocket 28 for power transmission is attached to the outside of the bearing 23, and the power from the motor 18 is transmitted to each material feeding roller 17 via a chain 19.

In the above structure, when the side surface and the bottom surface of the processed material are machined at the same time, first, the handle 4 is turned to set the depth of cut on the processed material bottom, the front table 5 is lowered, and the horizontal planing blade is used. 2 A step is provided between the cutting edge and the upper surface of the front table 5. This step becomes the cut amount of the processed material. To set the depth of cut on the side surface of the processed material, the handle 9 is also rotated to move the front guide 10 rearward, and a step is provided between the cutting edge of the vertical planer blade 9 and the guide surface of the front guide 10.

Next, when the processed material is placed on the front table 5 and the material-feeding device 16 is lowered and the material-feeding roller 17 comes into contact with the upper surface of the material-treated material, the material-feeding roller 17 causes the spring 24,
Since it moves upward against the biasing force of 25, a pressing force is applied to the processed material. When a switch (not shown) is turned on, the material-feeding roller 17 receives the power from the material-feeding motor 18 in the chain 1.
