Abstract

PURPOSE:To stably execute the supply of a slug by conveying a round column placing it lengthwise in the case of a small ratio of the height to the diameter of the round column and placing it sideways in the case of a large ratio of it according to the ratio of the height to the diameter of the round column and ejecting fluid on the way of dropping the round column to change the direction of the round column sideways. CONSTITUTION:The slug 1 for forging made in the round column shape by cutting a rod material is supplied to a forging machine 2. The slug 1 supplied from a parts feeder 3 is conveyed with a converyor 4 and a chute 5 is connected to this conveyor and further, a holder 6 for receiving the slug at the lower part and a pusher pin 7 for pushing out the slug in order are arranged. According to the ratio L/D of the height to the diameter of the round column, the slug having <= almost 1.5L/D is put lengthwise on the conveyor and the slug having >1.5L/D is put sideways on the conveyor and on the way of dropping, the fluid is ejected to change the direction of the column sideways and the column are stored in the holder 6 with the axes of the columns put sideways. By this method, the supply of the slug can be stabilized regardless of any ratio of L/D.

First, in FIG. 2, the slugs (1A) having a small L / D are arranged vertically on the conveyor (4), that is, the central axes thereof are parallel to each other. The end of the conveyor may be formed into a roll (41) as shown to rotate with the conveyor, may be in the form of a stationary roll separate from the conveyor, or may simply result in a slide. Good. The slag is pushed later and falls one after another. In any case, it is necessary for the way of connection to the shooter (5A) and the shape and dimensions of the inside of the shooter to ensure the rolling drop of the slug.

Next, in FIG. 3, the slugs (1B) having a large L / D are arranged laterally on the conveyor (4), that is, with their central axes substantially aligned. The fact that these fall into the shooter is the same as in the case of a slug with a small L / D in Fig. 2, and the way the connection to the shooter (5B) and the shape and dimensions inside the shooter ensure that the slug slides and falls. The fact that it is necessary to do so is the same as in the above case.
