Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long belt comprising a conveyer for conveying a long material such as aluminum or the like, a synthetic resin for extruding or roll forming in one direction, and another conveyor proceeding in a direction intersecting with the conveyor. The present invention relates to a transfer device that transfers a long material from one conveyor to another conveyor in a material conveying conveyor.

2. Description of the Related Art Conventionally, in processing lines for various products,
The material conveyed by the first roller conveyor is
As a device for transferring to a second roller conveyor arranged at a right angle on one side of the front end portion (storage zone) of the conveyor, the height of the second conveyor is set slightly higher than that of the first conveyor, and A plurality of transfer rollers are arranged between the rollers in the storage zone of the conveyor so as to be able to move up and down, and a material transfer cylinder is arranged on the other side of the storage zone. The material is carried into the storage zone in a state where it is lowered below the roller conveyor, and then the above-mentioned transfer rollers are raised to push the material from the first conveyor to the height of the second conveyor, and in that state the above-mentioned transfer is performed. It is known that a cylinder is used to extrude and transfer material onto a second roller conveyor.

[0003]

However, in the above-mentioned conventional apparatus, when the material is extruded onto the second conveyor, not only the alignment of the material is disturbed but also the material is scratched. After the material is pushed up to the height of the second conveyor, the material is transferred to the second cylinder by the transfer cylinder.
Until it is pushed out on the conveyor, it has to stop there and spend an idle time, and accompanying that, the introduction of new material into the storage zone, the preceding material is pushed up by the transfer roller and the storage zone is pushed up. However, even if it becomes empty, it is necessary to wait until the transfer roller descends below the first conveyor after the preceding material is extruded onto the second conveyor, and there is a drawback that the transfer work efficiency is low. An object of the present invention is to eliminate the conventional drawbacks.

[0004]

As means for solving the above-mentioned problems, the first invention of the present application is a first conveyor having a storage zone at the front end for conveying long materials in a cross shape,
In a long material conveying conveyor comprising a second conveyor arranged in a direction intersecting the storage zone of the first conveyor, one or more movable members are provided below the storage zone of the first conveyor. Arranged so as to be able to drive forward and backward along the convey direction of the conveyor, and in a state in which a plurality of long material transfer arms in total are extended in parallel with the convey direction of the first conveyor on the one or more movable members. Each of the long material transfer arms is moved up and down to a position corresponding to the storage zone and a position corresponding to the second conveyor by the forward / backward drive of the movable member, and is also moved up and down. Driven up and down to a position above the storage zone conveyor surface and the second conveyor surface and a position below the storage zone conveyor surface and the second conveyor surface In a positional relationship that, proposed a transfer device of long material conveyor,

A second invention of the present application is a first conveyor having a storage zone at a front end for carrying long materials in an intersecting shape, and a second conveyor arranged in a direction intersecting with the storage zone of the first conveyor. In a long material conveying conveyor consisting of, a plurality of rail members having a length extending from the storage zone to the second conveyor are extended below the storage zone and the second conveyor in parallel with the conveying direction of the first conveyor. In this state, it is supported by the crank means so as to be capable of swinging up and down, and the long material transfer arms are respectively extended to the rail members in parallel with the conveying direction of the first conveyor. The long material transfer arm is supported so that it can be moved back and forth along the transport direction.
By the vertical swinging drive of the crank means, the crank means is vertically moved to a position above the conveyor surface and the second conveyor surface of the storage zone and a position below the conveyor surface and the second conveyor surface of the storage zone, and the forward / backward drive is performed. Thus, a transfer device for a long material conveying conveyor is proposed, which has a positional relationship of moving back and forth between a position corresponding to the storage zone and a position corresponding to the second conveyor.
