[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a traveling frame device used in the field of a conveyer conveyor system, or a suitable metal frame material usable as a guide rail, a receiving rail, or the like. The present invention relates to a traveling frame device such as a conveyor chain configured by using this frame material.

[0002]

2. Description of the Related Art Conventionally, in this type of frame material, an iron or stainless steel frame material has been used. This frame material is formed by pressing a steel plate material having an appropriate thickness and an appropriate length. Alternatively, a bender was bent to make a simple long structure, and a plurality of these were connected to provide a structure. In addition, an aluminum frame material produced by extrusion processing is also used, and this frame material has an advantage that a complicated shape can be formed.

[0003]

However, the iron or stainless steel frame material as described above has a drawback that only a simple structure can be formed. A thick plate material must be used in order to obtain appropriate processing accuracy and rigidity, but if the plate thickness is increased, it becomes difficult to reduce the weight and cost, and there is a limit to the cost reduction and the weight reduction. In addition, if the frame material does not have processing accuracy and rigidity, a step is generated at the connecting portion between the frame materials, noise is generated, uneven transport speed occurs, and the transported object falls over. was there. Moreover, a sharp edge is generated due to the cutting process, which may injure the operator.

Further, the guide bracket and the bolts and nuts of the connecting portion may protrude from the side surface of the frame member, possibly injuring an operator. Moreover, the mounting position of the guide bracket can be mounted only at the position where the holes have been drilled in advance,
In the field, you have to re-drill and adjust,
The work takes time and the cost is high.

Further, in the aluminum frame material extruded as described above, there is a possibility that aluminum oxide compound may be generated when moisture or water is present in the transportation environment. That is, this aluminum oxide compound is harmful, and there is a problem in that it is not preferable in terms of hygiene not only in the food processing field but also in the environment working in other industrial fields. In addition, since the structure is such that water cannot be drained, there is a risk that residual water will rot and become unsanitary.
