Abstract

PROBLEM TO BE SOLVED: To surely fix a lumber on a carrying roller conveyer without a top clamp device by providing a fixing part of fixing a transverse clamp device and a lifting and lowering cylinder device for lifting and lowering the fixing part. SOLUTION: A lumber 6 is pressed and pinched from the left and right by extending cylinder rods 123 of cylinders 21 for transverse clamping. When a cylinder rod part 42 of a lifting and lowering cylinder device 4 is contracted and shortened while the lumber is pinched by transverse cylinder plates 20 as it is, a force for pulling down a fixing part 3 is worked and the lumber 6 is fixed by pushing the lumber 6 on the surfaces of rollers of a carrying roller conveyer 5. Under this fixed condition, the lumber 6 is cut into a required shape by a cutter for working and cutting.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a wood fixing device.

[0002]

2. Description of the Related Art In order to cut wood, it has been necessary to fix wood raw materials on a transport roller conveyor in the middle of the transport roller conveyor.

[0003] As shown in FIG. 4, a conventional timber fixing device includes an upper clamp device 80 located above the transport roller conveyor 5 and a horizontal clamp device 81 located on the right and left of the upper portion of the transport roller conveyor 5 to move the upper portion of the transport roller conveyor. The conveyed wood 6 was pressed from above on the conveying roller conveyor 5 and was pinched from the left and right.

The upper clamp device 80 is moved vertically by an upper clamp cylinder, and the left and right lateral clamp devices 81 are moved laterally by a lateral clamp cylinder.

Further, the entire upper clamp device 80 is suspended from above the ceiling or the like, and the entire upper clamp device 80 moves downward each time wood is fixed. After being moved downward, the cylinder was moved, and the upper surface of the wood 6 was pressed onto the transport roller conveyor 5 by the upper clamp device 80.

[0006]

In the conventional wood fixing device, each clamp is independently provided, so that separate cylinder operating devices are required for the upper clamp device and the lateral clamp device. Was.

[0007] Further, the upper space of the conveyor is moved upward by the moving clamps every time the moving clamp is moved so that the moving clamps other than these clamps move on the conveyor, so that they do not hinder the movement. Had to be raised to

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view of a wood fixing device according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the same, and another embodiment of the present invention. A description will be given with reference to FIG.

The wood fixing device 1 comprises a horizontal clamping device 2, a fixing portion 3, and a lifting / lowering cylinder device 4.

The horizontal clamp device 2 includes left and right horizontal clamp plates 20 for pressing the wood 6 conveyed on the conveying roller conveyor 5 from right and left, and a horizontal clamp cylinder 21 for opening and closing the horizontal clamp plate 20. The horizontal clamp plate 20 is a plate-like body that is long in the longitudinal direction of the wood 5 and is erected right and left in parallel with the transport roller conveyor 5. Each horizontal clamp plate 20 is connected to a cylinder rod 23 of each horizontal clamp cylinder 21 via a support portion 22 on an outer surface of a plate-like body that stands upright in parallel with the transport roller conveyor 5. The support portion 22 is a bar-shaped body that is provided in a plurality of positions and has a thickness that allows the support portion 22 to enter from the lower left and right sides of the transport roller conveyor 5 without contact between the individual rollers of the roller conveyor, and to have a thickness. It is connected and fixed to the cylinder rod 23 of the clamping cylinder 21. As another embodiment of the support part 22, the horizontal clamp plate 20
The rod-shaped body extends in a substantially horizontal direction, and the rod-shaped body is connected and fixed to the cylinder rod 23 of the horizontal clamping cylinder 21.

One horizontal clamping cylinder 21 is provided horizontally on the upright wall portion of the fixed portion 3, and a cylinder rod portion 24 is provided.
Side facing the transport roller conveyor 5. In this embodiment, the horizontal clamping cylinder 21 is one of the fixing portions 3.
One cylinder rod 2 is provided for one standing wall portion 31.
The left and right horizontal clamp plates 20 press and clamp the conveyed wood 6 due to the expansion and contraction of 3 (FIGS. 1 and 2).

As another embodiment, two horizontal clamping cylinders 21 are provided, and the cylinders 21 are provided horizontally on the left and right standing wall portions of the fixed portion 3, respectively.
4 may be provided so as to face the transport roller conveyor 5 (FIG. 3).

The fixed portion 3 is provided below the conveyor 5 and includes a flat portion 30 and an upright wall portion 31.
The plane portion 30 is formed of a plate-like body provided horizontally below the transport roller conveyor 5. The standing wall portion 31 is a flat portion 3
0 on both sides of the conveying roller conveyor 5 in the vertical direction.

The fixing portion 3 is fixed to the cylinder rod portion 40 of the lifting cylinder device 4 on the lower surface side of the flat portion 30. The cylinder rod portion 40 is slidably fitted to the elevating guide 41. The elevating guide 41 is erected in parallel with the cylinder rod portion 40 and fixed to the floor surface 7.
The cylinder portion 42 of the lifting cylinder device 4 is fixed to the floor surface 7.

Next, the operation of the present invention will be described. The wood 6 conveyed on the conveyor 5 is cut by the cutter 8 and is fixed on the conveyor 5 at a predetermined position.

When the wood 6 conveyed on the conveyor 5 is sensed by a positioning stopper (not shown), the wood 6 stops on the conveyor 5.

Next, in response to a signal from the positioning stopper, the cylinder rod portion 42 of the lifting cylinder device 4 extends, and the fixing portion 3 fixed to the cylinder rod portion 42 also rises. At this time, the horizontal clamping cylinder 21 fixed to the vertical wall portion 31 of the fixing portion 3 in the horizontal direction is shortened, and the horizontal clamp plate 20 is widely opened to the left and right.

The elevating cylinder device 4 stops when the fixed portion 3 is raised by the extension of the cylinder rod portion 42 of the lifting cylinder device 4 and the height of the horizontal cylinder plate 20 becomes the same as the height of the wood 6. I do.

Next, one or two left and right cylinder rods 23 of the horizontal clamping cylinder 21 are extended to press and hold the wood 6 from the left and right. At this time, if the support portion 22 is an embodiment of a bar-shaped body that is erected, the support portion 22 can enter between the rollers of the roller conveyor 5, so that the horizontal cylinder plate 20 can reliably press and hold both surfaces of the wood 6.

When the cylinder rod portion 42 of the elevating cylinder device 4 is shortened while the wood 6 is sandwiched by the horizontal cylinder plate 20 as it is, the force for pulling down the fixing portion 3 acts, and the wood 6 is transferred to the conveyor roller conveyor 5. It is pressed against the roller surface and fixed. In this fixed state, the wood 6 is cut into a required shape by a working cutter. After cutting, the fixing portion 3 is moved up and down again by the lifting / lowering cylinder device 4 in the reverse operation, and the horizontal clamping cylinder 2
The first cylinder rod 23 is shortened to release the holding of the wood 6, and then the fixing unit 3 is lowered again by the lifting cylinder device 4.

[0023]

Therefore, according to the present invention, wood conveyed on the conveyor roller conveyor can be securely fixed on the conveyor roller conveyor without an upper clamp device.

[0024] Therefore, it becomes very easy to move the moving clamp that moves on the transport roller conveyor and to perform other operations near the transport roller conveyor.
