A delivery member that scoops the bar material from below and delivers it to the receiving member while gradually advancing the following bar material to the front row; and a receiving member that receives the bar material received on the receiving member by the receiving member. An upper edge extending in a direction intersecting with the edge and connected to the surface of the supporting roller is pushed up from below by an upper edge to feed the bar material to the supporting roller, and a feeding member movable up and down together with the supporting roller is adopted. ing.

Further, if necessary, the above-mentioned feeding member adopts a structure in which the position of the top dead center can be adjusted according to the diameter of the rod.

[0009]

[Function] The shelf member horizontally supports a large number of bars. The bar is put on the shelf member in a pressed state and stopped.

When sending one bar to the support roller, the delivery member gradually advances the bar in the front row from below to the scooping-up receiving member while advancing the subsequent bar to the front row. This causes the subsequent bar on the shelf to slowly advance and quietly stop. Further, the one bar taken out is gently received by the substantially horizontal receiving edge of the receiving member.

Next, the feeding member rises and pushes the bar toward the supporting roller while the upper edge of the feeding member crosses the receiving edge of the receiving member. As a result, the bar member slowly rolls into the support roller.

If the diameter of the rod is increased, the amount of feeding of the feeding member is increased, which causes excessive momentum and causes noise. According to the present invention, by lowering the position of the top dead center of the feeding member as the diameter of the rod increases, the rod can be fed toward the support roller with an appropriate force.
