Reference numeral '20' is a 'transfer chain' used to transfer the fishing needle material 1 cut to a predetermined length in the fishing needle maker 100 of FIG.

The transfer chain 20 serves to transfer a fishing needle material 1 of a predetermined length from a material input position I of the fishing needle maker 100 to a material discharge position O for discharging the processed material. Do it.

Here, the material input position (I) is a position where the material is supplied from the material input device 110, the material discharge position (O) is dragging the material to the bending device 120 to form a hook by bending the end of the material Is the initial location for

The transfer chain 20 has a pair of inner side plates 21 and 21 having material hanger grooves 21a and 21a on the upper surface, and the inner side plate 21 and 21 having the same material hanger grooves 25a and 25a on the upper surface. A pair of outer side plates (25, 25) rotatably coupled to each other on both ends of the outer side and rotatably coupled via a hinge pin (24) into which a cylindrical roller (23) is inserted is alternately connected in a row to form a closed type. It is made up of structures.

At this time, the inner side plates 21 and 21 have a bent portion 21b in the middle so that the upper side section L of the bent portion 21b is located on the same plane as the outer side plates 25 and 25.

The transfer chain 20 is disposed in a substantially square shape in front of the table 102 and is separated by upper sprocket wheels 31 and 32 and lower sprocket wheels 33 and 34.

At this time, the upper sprocket wheels 31 and 32 serve to move a portion of the transfer chain 20 from the material input position I to the material discharge position O.
