Description

[0001]
BACKGROUND OF THE INVENTION
This invention is a processing step for processing wood such as plate material and square material, and simultaneously feeds a plurality of the above-mentioned wood to be processed with a feed roller, aligns the end face (the end) of the wood, and in that state the wood The present invention relates to a feeding table for clamping and sending to the next process.
[0002]
[Prior art]
Conventionally, in order to process the end faces of multiple pieces of wood at the same time, a feed table that feeds multiple pieces of wood at the same time with a rotating feed roller, abuts it against the front stopper, and aligns the mouth of each piece of wood has been used Yes.
[0003]
[Problems to be solved by the invention]
By the way, if you feed several pieces of wood such as plates and squares at the same time with a feed roller, the wood and wood will interfere with each other depending on the state of the wood, i.e., bending, twisting, surface finish, etc. By simply sending in, there is a difference in the distance that each piece of wood is sent, and when the wood comes into contact with the stopper in front of the incoming table, not all the wood ends are surely aligned, Even if the feed roller continues to rotate in order to align the timber ends in that state, the timbers interfere with each other and the feed roller and the wood slip, making it impossible to completely align the timber ends.
[0004]
In such a state, when the wood is clamped and sent to the next process and the end is processed, the wood that is in contact with the stopper is processed, but the wood that is not in contact is unprocessed and becomes a defective product. There is a problem.
[0005]
In addition, since the conventional stopper is a fixed type, when loading and unloading wood to and from the table, the wood is loaded and unloaded from the direction where there is no stopper, or the table is moved to a position where there is no stopper and the wood is loaded. It was necessary to carry it out.
[0006]
Therefore, the problem of the present invention is that even in the wood in the state as described above, the mouth of each wood can be reliably brought into contact with the stopper, and the mouth can be aligned and clamped and sent to the next process. It is an object of the present invention to provide a feeding table that can carry wood into and out of the table beyond the stopper, and improve the degree of freedom of the wood transportation line.
[0007]
[Means for Solving the Problems]
To solve the above problems, the present invention is a stopper disposed in front of the feeding direction of the table to send a timber plurality of lined to the length direction support, the position of the upper at the distal end side of the table In the feeding table provided with the upper clamp and the side clamp at one side position, the surface for supporting the wood and feeding it in the length direction is a smooth feed roller, and a projection on the surface. a mix of rollers having provided, the position of both sides of the table, and moves back and forth in a direction perpendicular to the feeding direction by the roller, adopting a structure in which a lateral pressure assisting cylinder to correct the attitude of the alignment condition of timber Is.
[0008]
The stopper is in a horizontal stopper rod drive machine, it is formed so as to be possible to change the position in one of the states located in the state and the lower positioned above the upper surface of the feed roller structure It is good .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
As shown in the figure, the feed table 1 is provided with a feed roller 3 having a smooth surface on a long table 2 arranged at predetermined intervals in the length direction, and between the feed rollers 3 at appropriate positions. The roller 5 having the protrusions 4 on the surface is provided in a mixed arrangement, the feed roller 3 is rotationally driven to feed the wood A and always forward, and the roller 5 having the protrusions 4 on the surface is always rotated. Alternatively, the rotation may be performed only when necessary, and the projection 4 is in contact with the lower surface of the wood A supported by the feed roller 3 during the rotation.
[0011]
The feeding table 1 has both ends of the table 2 supported by rails 7 on a base table 6 and a moving mechanism 10 by a rack 8 and a pinion 9 in a direction perpendicular to the feeding direction of the wood A by the feeding roller 3. Is supposed to move by.
[0012]
At the position where the feeding table 1 stops on the wood A supply line, the feed table 3 stops at the front position in the feed direction of the wood A by receiving the end of the wood A sent by the feed roller 3. A stopper 11 is provided by being placed on the base table 6.
[0013]
As shown in FIG. 1, the stopper 11 pivotally supports a swing arm 11a on a support base 12 provided on a base base 6, and a horizontal stopper rod 13 is attached to the upper end of the swing arm 11a. The cylinder 14 is connected to the lower end of the swing arm 11a, and the expansion and contraction of the cylinder 14 changes the stopper rod 13 to either the upper position or the lower position relative to the upper surface of the feed roller 3. In order to be able to do so, it is possible to move up and down freely so as to lie down on the opposite side of the feeding table 1 from the protruding state. The stopper 11 may employ a mechanism that slides in the vertical direction.
[0014]
As described above, when the stopper rod 13 of the stopper 11 can be positioned below the upper surface of the feed roller 3, the wood A can be sent out in the extending direction of the feed table 1, and the wood transport line There is an advantage that the degree of freedom of setting is greatly improved.
[0015]
On the front end side in the feed direction of the wood A by the feed roller 3 of the feed table 1, side pressure auxiliary cylinders 15 and 16 are located at both side positions, an upper clamp 17 is located at the upper position, and a side position is located on one side. A part clamp 18 is provided.
[0016]
The side pressure auxiliary cylinders 15 and 16 are horizontally fixed so as to be coaxially arranged on both side surfaces of a gate-shaped support frame 19 provided on the table 2, and a vertical push plate 20 attached to the tip of a piston rod. Face each other and move forward and backward in a direction orthogonal to the feeding direction of the wood A by the feed roller 3, and the wood A group supported on the feed roller 3 during the forward movement is sandwiched from both sides.
[0017]
As shown in FIG. 1, the upper clamp 17 is positioned on the tip side of the side pressure auxiliary cylinders 15 and 16 and vertically fixes the cylinder 22 to the upper portion of the portal support 21 provided on the end side of the table 2. The horizontal pressing member 23 is provided at the lower end of the piston rod facing downward of the cylinder 22, and the wood A group supported on the feed roller 3 is pressed and fixed from above.
[0018]
As shown in FIG. 2, the side clamp 18 has a cylinder 24 fixed horizontally to one side surface of a gate-shaped support base 21 provided with an upper clamp 17 and the tip of a piston rod facing the inside of the feeding table 1. A vertical pressing member 25 is provided to press the timber A group from the side surface and is fixed to the other side surface of the gate-shaped support base 21 . In addition, this side clamp 18 is provided in the position which becomes the back side with respect to the direction where the feeding table 1 moves toward a processing machine.
[0019]
Although not shown in the drawings, the rear end side of the feeding table 1 is also provided with a side pressure auxiliary cylinder at both positions, an upper clamp at the upper position, a side clamp at one side position, and the feed roller 3. The stopper 11 which receives the edge part of the sent wood A is provided, and after the processing of the front end part of the wood A is finished, each clamp is released, the feed roller is reversed, and the wood A is fed in the opposite direction. You may make it process a rear-end part similarly to.
[0020]
The sending-in table of the present invention is configured as described above, and the operation thereof will be described next.
When a plurality of pieces of wood A are supplied side by side from the rear end side while the feed table 1 is stopped on the wood A supply line, the feed table 1 rotates the feed roller 3. When the front end of the wood A comes into contact with the front stopper 11 and the front end of each wood A is not aligned, the side pressure auxiliary cylinders 15 and 16 on both sides of the feed table 1 are installed. Move forward, pinch the wood A group from both sides, and correct the posture of the wood A alignment.
[0021]
Thereafter, when the roller 5 having the protrusion 4 on the surface is rotated while the side pressure auxiliary cylinders 15 and 16 are moved backward, vibration is applied to the wood A by the protrusion 4 of the roller 5. Combined with the effects of 15 and 16, the state where the wood A has been obstructed until then is eliminated, so that the wood A that is not in contact with the stopper 11 moves forward by the rotation of the feed roller 3, and the end of the wood is the stopper 11. Abut.
[0022]
In this way, when all the timbers of the wood A are brought into contact with the stopper 11 and the timbers are securely aligned, the rotation of the feed roller 3 is stopped, the upper clamp 17 and the side clamp 18 are operated, and the wood A group is moved. Fixed to the incoming table 1.
[0023]
In this state, the stopper 11 moves the stopper table 13 away from the mouth of the wood group A, and then the feed table 1 moves toward the next process, and the end of the wood A is processed such as a finger joint. The
[0024]
【The invention's effect】
As described above, according to the first aspect of the present invention, when a plurality of pieces of wood are fed toward the end processing machine in a parallel state, the end ends of each piece of wood can be reliably aligned, It is possible to reliably prevent the generation of defective products when the end portions are processed simultaneously.
[0025]
According to the second aspect of the present invention, the position of the stopper can be changed between the upper position and the lower position with respect to the upper surface of the feed roller. Wood can be carried in and out of the table, and the degree of freedom of the wood transportation line can be improved.
