Abstract

PURPOSE: To provide a wrought timber transport device comprising a mobile device provided between a vertical feed conveyor and a traversing feed conveyor. CONSTITUTION: A wrought timber is clamped by transporting a wrought timber using a belt 7 of a traversing feed conveyor 1 and activating a clamping cylinder 17 at a specified position with the help of a clamping member 18 on a clamping device 16. Next, a lift table 14 and a mobile table 13 are caused to ascend by activating an ascending cylinder 31 in front of a vertical feed conveyor 26. Then if the clamping device 16 arrives above the roller 28 of the vertical feed conveyor 26, a motor 24 is driven to move the clamping device 16. In this case, if the wrought timber hits the ruler 29 of a roller 28, the clamping cylinder 17 is activated to release the clamp of the clamping member 18 and the wrought timber is positioned along the ruler 29. Further, the clamping device 16 descends past the vertical feed conveyor 26, and if the device comes down to a specified position, it moves forward to a position where the traversing feed conveyor 1 receives the wrought timber and stands by.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work material carrying-in device in which a clamp device of a moving device provided between a vertical feed conveyor and a horizontal feed conveyor is moved forward and backward and up and down.

[0002]

2. Description of the Related Art In a conventional work material carry-in device, a work material sent from a horizontal feed conveyor is clamped by a clamp portion of a moving device and placed on a vertical feed conveyor that moves at a right angle to the horizontal feed conveyor. The processing material is sent to the processing device by the vertical feed conveyor, and when the processing is completed, it is sent to the next processing device.

[0003]

By the way, since the horizontal feed conveyor and the vertical feed conveyor are provided at the same height in this conventional work material carry-in device, the clamp portion of the moving device is above the work material feed conveyor. After placing the workpiece on the conveyor, the workpiece cannot be moved to the position where it is clamped, and after the workpiece on the feed conveyor has passed, it is moved to the clamp position on the conveyor. There was a problem of being bad.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a vertical feed conveyor provided with a roller for moving a workpiece along a ruler provided on one side, and a plurality of the vertical feed conveyors at right angles to the vertical feed conveyor. A moving device provided with an elevating cylinder that is mounted so as to move the clamping device to each of a plurality of movable carriages that are mounted so as to be divided, and a moving device provided with an elevating cylinder that simultaneously elevates and lowers the plurality of movable carriages; It is provided at a low position and comprises a transverse feed conveyor for feeding the processed materials one by one to the clamp device of the moving device.

[0005]

According to the present invention, the height of the vertical feed conveyor is made higher than the height of the horizontal feed conveyor, so that the clamp member of the clamp device of the moving device provided between the horizontal feed conveyor and the vertical feed conveyor is more than the horizontal feed conveyor. Clamp the sent work material, move the clamp device toward the vertical feed conveyor, stop the clamp device in front of the vertical feed conveyor, raise the moving table and move the clamp device further to move the work material vertically. After placing it against the ruler on the side of the roller of the feed conveyor, lower the moving table, and the clamp device goes under the work material and returns to the position where it clamps the next work material, thereby You can go to the next processed material with the clamp device without waiting for the next processed material to pass.

Further, before the work material from the horizontal feed conveyor is placed on the vertical feed conveyor, the front end of the work material is further cut by a saw so that the tip of the work material placed on the vertical feed conveyor is further cut. No need to disconnect.

A plurality of belts 7 are hung on each of the belts 6, and these belts 7 are mounted in parallel with each other.

An intermittent cylinder 8 is mounted in the vicinity of the pulley 6 at the opposite position, and an operating shaft 9 of the intermittent cylinder 8 is connected to a rotary shaft 10 and is provided on the rotary shaft 10 in parallel with the belt 7. A large number of processed materials sent by the arm 11 are blocked so as to be sent one by one.

Further, in parallel with the transverse feed conveyor 1, a moving device 12 having a plurality of movable carriages 13 provided further ahead of the pulley 6 is mounted, and these movable carriages 13 are fixed on an elevating carriage 14. Clamping devices 16 are respectively placed on rails 15 on these moving bases 13, and these clamping devices 16 are clamp members 18 whose intervals are changed by a clamp cylinder 17 and which are sent from the lateral feed conveyor 1. Clamp the material.

The ends of the chain hooked between the gear 19 attached to one end of the moving table 13 and the gear 21 fixed to the rotary shaft 20 attached to the other end of the moving table 13 are located at the front and rear of the clamp device 16, respectively. Hanging parts 22, 2 fixed to the
The motor 24 mounted on the lifting table 13
The clamp device 16 moves on the rail 15 of the movable table 13 by rotating the gear 25 of the rotary shaft 20 at.

Further, the movable table 13 is mounted so as to cross between the vertical feed conveyors 26, and a large number of rollers 28 are mounted on the upper end of the support base 27 of the vertical feed conveyors 26, and one side of these rollers 28 is mounted. A ruler 29 is attached, and all of the rollers 28 are configured to be rotated by a motor 30 so as to feed the work material vertically along the ruler.

Further, the operating shafts 32 of the two lift cylinders 31 provided at intervals are fixed to a support rod 33 fixed to the upper end of the support base 27, and the main bodies of these lift cylinders 31 are movable bases 13. The movable table 13 is fixed to the lifting table 14 and the moving table 13 is lifted together with the lifting table 14 when the lifting cylinder 31 is operated.
