[0003]

However, in the above-mentioned conventional chain belt conveyor 10 which is a round material conveying mechanism, in order to accurately place the cut round material 11 on the locking portion 12 provided on the chain belt 13, It is necessary to synchronize the timing of loading the round material 11 with the loading time, and a power unit or the like is required, which complicates the mechanism.
Further, there is a problem that maintenance is troublesome. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a round material conveying mechanism having a simple mechanism, less likely to cause a failure, and easy to maintain.

[0004]

A method according to the above-mentioned object.
The round material carrying mechanism described is a round material carrying mechanism in which a plurality of guide members are arranged in a carrying direction of the round material, and a round material having a circular cross section is rolled and carried on the guide member. 3 or more corresponding to each other, only the both ends of the round material are placed on the guide member, and the guide member inside the guide member on which the round material is placed is It is placed low enough to form a small gap between them. The round material carrying mechanism according to claim 2 is the round material carrying mechanism according to claim 1, wherein the guide member with which both ends of the round material abut is arranged such that the downstream side thereof is slightly widened with respect to the carrying direction of the round material. . Here, the round material having a circular cross section may be rod-shaped or tubular. The material may be any one of metal material, wood, synthetic resin material and the like. The guide member is not limited to one provided with an inclination on the downstream side with respect to the conveying direction of the round material in consideration of the momentum for mounting the round material, and may be one provided horizontally with respect to the ground.
Further, the guide member is preferably cylindrical or rod-shaped having a circular cross section, but may be a columnar body or a cylindrical body having various cross-sectional shapes such as a polygon such as a triangle or a square or an L-shape.

[0005]

In the round material conveying mechanism according to the first and second aspects, two guide members corresponding to a predetermined length of the round material to be conveyed are selected from three or more guide members arranged side by side, and both end portions of the round material are selected. To place. Next, the round material is rolled and conveyed on the guide member due to the momentum or inclination of the guide member that is placed. And, the height of the rolling member is adjusted so that only the both ends of the rolling member are always placed on the guide member, and the guide members have a small gap except the both ends of the rolling member. Only the both ends of the round material roll while contacting the guide member. Therefore, even with a round member having an eccentric axis, the portions other than both ends of the round member do not contact the guide member to change the traveling direction. Particularly, in the round material carrying mechanism according to the second aspect of the present invention, since the guide members that come into contact with the both ends of the round material are arranged such that the downstream side thereof is slightly widened with respect to the carrying direction of the round material, the predetermined length is particularly long and heavy. For round material, the distance between the fulcrums on both sides expands during the rolling process on the downstream side.
As a result, the bending gradually increases, and it becomes difficult for the rolling round material to move in the axial direction. Therefore, the round material rolls to the end of the guide member without coming off the guide member while rolling.
