Product recovery apparatus and product recovery method

#The present invention relates to a product recovery apparatus and a product recovery method in which after a product has been processed, the processed product is automatically recovered.

#There have been machine tools, for example, automatic lathes for supplying a longitudinal bar material through a through hole of a main shaft from a back part of the main shaft, feeding the bar material in a main shaft axis line direction by each predetermined length, and continuously performing processing such as turning and grinding, or for supplying a material for one product to the main shaft from a front part of the main shaft by a robot, and the like.

#Among these, in the former machine tool, the tip end of the bar machine tool is projected from the tip end of the main shaft by a predetermined length, a tool rest or head stock is moved to perform predetermined processing, and thereafter a product is cut from the bar machine tool with tools such as a cut-off tool. Subsequently, the cut/separated product is recovered by a product recovery apparatus.

#FIG. 1 is a schematic view of a main part of an automatic lathe including a product recovery apparatus according to a first embodiment of the present invention;

#FIG. 2 is a partially broken plan view seen from right above a recovery container of FIG. 1;

#FIGS. 3(a) and 3(b) are explanatory views of a constitution and function of a valve for opening/closing a discharge port of coolant, wherein FIG. 3(a) is a sectional view showing a state in which a discharge port is closed, and FIG. 3(b) is a sectional view showing a state in which the discharge port is open;

#Preferred embodiments of the present invention will be described hereinafter in detail with reference to the drawings.

#[First Embodiment]

#First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and 6.
