Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a material receiving stand for a woodworking machine that holds and sends the material to a woodworking machine such as an automatic plane.

[0002]

[Prior Art]

 In the conventional device, as described in Japanese Utility Model Publication No. 58-31663, a vertically movable piston rod is provided at the center of the material receiving table, a rotary table is provided at the tip of the piston rod, and a column member is mounted on the rotary table. There was a system to raise the piston rod and lift up the pillar material, and the operator rotated the pillar material to invert the pillar material and efficiently perform tenon processing at both ends of the pillar material.

[0003]

[Problems to be solved by the device]

 The conventional material reversing device reverses the front and rear of the pillar material.When processing the surface of the pillar material with an automatic plane, the operator lifts the pillar material using a chain block and rolls it upside down. There was a need. Therefore, the work is troublesome, and there is a risk that the hand may be caught between the pedestal and the pillar material when the vehicle rolls over. SUMMARY OF THE INVENTION An object of the present invention is to provide a material overturning device which eliminates the above-mentioned drawbacks of the prior art and can easily overturn a column member and eliminate the danger of work.

[0004]

[Means for Solving the Problems]

 According to the present invention, a piston rod that moves up and down is provided in the lower center of the pedestal, and a tilting table that can tilt is pivotally supported at the tip of the piston rod. To support.

[0005]

[Action]

 The material rollover device configured as described above pushes out the fluid pressure cylinder below the pedestal to raise the tilt table. Then, the pillar member placed on the cradle is separated from the roller and supported on the tilting table. The tilt table tilts as it continues to rise, tilting the material to the tilt guide side. The tilt guides tilt and support the pillar material in conjunction with the tilt of the pillar material. As the tilt table continues to rise, the pillars roll off from the tilt table and return to above the rollers with the tilt guide surface as a guide.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. In the figure, a pedestal 3 is mounted on a base 1 via an elevating device 2, and the pedestal 3 faces a tilt table 5 and a tilt table 5 which can be vertically moved and tilted by a fluid pressure cylinder 4. The tilt guide 6 is arranged at the position. The elevating device 2 pivotally supports the intersection of the link member 7a pivotally supported by the base 1 and the link member 7b pivotally supported by the pedestal 3, and can slide the other end of each link member 7a, 7b. It is formed by abutting against the base 1 or the cradle 3 and further by mounting a jack 8 between the base 1 and the cradle 3 to change the height thereof by the rotation of a screw. Rollers 9 that support the pillar member 14 so as to be movable back and forth are mounted in parallel on the pedestal 3. Further, the fluid pressure cylinder 4 is mounted movably in the width direction of the roller 9 on the holder 10 at the lower center of the pedestal 3, and is fixed by the knob bolt 11. The piston rod 4a penetrates upward from the center of the pedestal 3, and a tilt table 5 is tiltably attached to the tip of the piston rod 4a via a bearing, and is locked by a spring 12 to the side opposite to the work material. There is. A tilt guide 6 is attached to the upper part of the pedestal 3 so as to face the tilt table 5 so as to be tiltable via a bearing, and is locked to the work material side by a spring 13. The material overturning device for a woodworking machine configured as described above is used, for example, as a cradle for a material automatic return type plane. In the above structure, the lifting device 2 is moved by the jack 8 to change the height of the pedestal 3, the table surface of the plane 15 and the position of the roller 9 are aligned, and the pillar 14 is placed on the roller 9 of the pedestal 3. Place it. At this time, the piston rod 4a of the fluid pressure cylinder 4 is in the lowered position, and the tilt table 5 is not in contact with the column member 14. The holder 10 is moved to the left and right, the position of the tilt table 5 is adjusted to the width of the pillar material and fixed with the knob bolts 11, and the pillar material 14 is fed into the plane board 15, and after the one-sided processing, the pillar material 14 is returned to the cradle 3. Return. Next, the fluid pressure cylinder 4 is pushed out to raise the tilt table 5. Then, the column member 14 gradually inclines with one end in contact with the roller 9. The tilt guide 6 tilts following the tilt of the pillar 14 and supports the pillar 14. As the tilted table 5 continues to rise, the pillar material 14 rolls off and comes off, and slides down onto the roller 9 using the surface of the tilted guide 6 as a guide. After the column member 14 rolls over, the tilt table 5 and the tilt guide 6 are urged by the springs 12 and 13 to return to the initial state positions. The fluid pressure cylinder 4 is pulled back, the inclined table 5 is lowered, and the unprocessed surface of the pillar 14 is fed to the plane 15 to perform surface processing.

[0007]

[Effect of the device]

 According to the present invention, it is not necessary to use a tool such as a chain block when processing each surface of a pillar material, and the operator does not have to roll the pillar material sideways, which is efficient and safe. It is possible to roll over pillars.
