[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a pipe conveyor for transporting conveyed objects such as powders and granules, and more particularly to a pipe for converting a conventional trough conveyor using a flat belt into a pipe conveyor. It relates to the structure of the conveyor.

[0002]

Efficient Recently, transport operations, for the purpose of improving the environment and the like of the work site, powders, an existing trough conveyors using flat belts transporting the transport of granules or the like, to Paipukonbe ya Remodeling has been done. Immediately Chi, using the trough conveyor comprising turning Suspend the endless conveyor belt through a plurality of return rollers disposed between the F <br/> Ddopuri and Terupuri, powder, transport of granules such as When transporting goods, the conveyed matter that had adhered to the surface of the conveyor belt turned over from the head pulley to the return side and moved to the tail side. In such a case, there is a problem that the lower part of the conveyor device and its vicinity are polluted because they scatter around and the environment is deteriorated. For this reason, in recent years, a trough conveyor for transporting a conveyed object such as a powder or a granular material has been recently modified into a pipe conveyor.

[0003] However, the return side of the existing facilities of the trough conveyor, to remodel the Paipukonbe ya, it is necessary to perform tasks such as the following. First, stop the conveyor line, cut the endless conveyor belt, take out the return side conveyor belt to be remodeled from the conveyor line, then remove the return roller and roller support plate fixed to the frame, return A new frame (angle) is installed in the width direction in accordance with the required pitch of the roller support plate for the pipe conveyor, and a new frame (angle) is installed in the longitudinal direction. The roller support plate is fixed to this frame by bolts or welding. And
The conveyor belt is rolled up and sequentially inserted into a roller support plate, and the end portions of the conveyor belt are connected to form an endless shape.

[0004]

However, in the case of the conventional remodeling method as described above, the conveyor cannot be operated at all during the remodeling period of the conveyor line. a conveyor system, is at present, can not be modified to Paipukonbe ya, to Paipukonbe ya, remove the existing equipment,
There is a problem that a large amount of equipment cost and labor are required, such as installation of a new frame.

The present invention has been devised in view of such a conventional problem, and allows an existing trough conveyor to be continuously and continuously modified into a pipe conveyor without stopping operation for a long time. An object of the present invention is to provide a structure of a pipe conveyor in which a pitch of a roller support plate can be easily changed, and a conveyor device can be easily and inexpensively modified.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an upper horizontal beam and a lower horizontal beam on a vertical frame of a frame-shaped conveyor frame erected along the direction of conveyance of a conveyor belt. the parallel fixed at predetermined intervals, at positions above and below phase opposite of the upper horizontal beam and the lower horizontal beam, an upper water along the conveying direction of the conveyor belt
The flat beam and the lower horizontal beam are fixed, and the upper horizontal
The gist is that a roller support plate through which the conveyor can be inserted is attached at a predetermined pitch to the beam and the lower horizontal beam via a plurality of bolts that can be moved or positioned and fixed.

[0007]

The present invention is constructed as described above. When a trough-type belt conveyor of existing equipment is converted into a pipe conveyor, in particular, the existing trough-type conveyor is operated without stopping the pipe conveyor for a long period of time. The pitch of the roller support plate can be easily adjusted by simply loosening the bolt and moving it along the upper horizontal beam and the lower horizontal beam . The conveyor device can be easily and inexpensively modified.

[0008]
