BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material feeding / introducing device which is used in a processing machine such as a saw and a punching machine and which has an infeed conveyor and a supply conveyor.

[0002]

2. Description of the Related Art A conventional material supplying and carrying-in device will be described. A carrying-in conveyor for carrying material such as shaped steel in the carrying-in direction (rearward direction) is arranged near the front side of a processing machine such as a saw machine. The carry-in conveyor includes a large number of carry-in rollers rotatable in the carry-in direction. This carry-in conveyor is composed of a plurality of divided conveyors that are adjacent to each other in the front and rear.

On one side (for example, on the left side) of the carry-in conveyor, a length-measuring guide is provided extending in the front-rear direction,
The length-measurement guide is provided with a length-measurement carriage provided with a clamp device for gripping a part of the material so as to be movable in the front-rear direction. On the other side of the carry-in conveyor (for example, on the right side)
Is provided with a supply conveyor that conveys the material in a supply direction (left direction) orthogonal to the carry-in direction, and the supply conveyor is provided with a plurality of supply chains that are adjacent to each other in the front and rear,
Each supply chain extends in the left-right direction.

In order to transfer the material from the supply conveyor to the carry-in conveyor, a part of each supply chain is configured so as to enter the carry-in conveyor, and the carry-in roller of the carry-in conveyor is relatively high with respect to the carry-in conveyor. The position is adjustable.

Therefore, after supporting a plurality of materials on the supply conveyor, the supply chain in the supply conveyor is moved in the supply direction so that the material is conveyed in the supply direction and positioned in the carry-in area of the conveyor.
Next, the material can be delivered from the carry-in conveyor to the supply conveyor by making the carrying height position of the carry-in conveyor (the height position of the carry-in roller) relatively higher than the supply conveyor. After the material is delivered, a part of the material is grasped by the clamp device, so that the material and the measuring carriage are integrated. By appropriately operating the carry-in conveyor, the material can be carried in the carry-in direction integrally with the length-measuring carriage and carried into the saw machine. At this time, the material can be loaded and positioned at a predetermined position in the loading direction by controlling the loading conveyor based on the detected value while appropriately detecting the movement amount of the length measurement carriage.

[0006]

However, as described above, since the material is delivered from the supply conveyor to the carry-in conveyor, the height of the plurality of carry-in rollers in the carry-in conveyor is adjustable relative to the supply chain. In addition to, it is necessary to position a part of the supply conveyor in the transport area of the carry-in conveyor, the supply conveyor is stretched in the supply direction,

[0036]

As will be understood from the above description of the embodiments, according to the invention of claim 1, the part of the supply conveyor is not located in the carry-in area of the carry-in conveyor, Since the material can be delivered from the supply conveyor to the carry-in conveyor reliably and appropriately by passing the material over the length-measuring guide by the material transfer table, it is possible to prevent the supply conveyor from extending in the supply direction as much as possible. As a result, it is possible to suppress the complication of the configuration of the material supply and carry-in device and the size increase of the material supply device as much as possible.

Since the length-measuring guide is provided in the vicinity of the transport reference position on the carry-in conveyor, it is not necessary to extend the length-measuring carriage in a direction intersecting the carry-in direction. The long carry-in and length-measuring guide improve the accuracy of material loading and positioning.
