Abstract

A power consumption output device for an apparatus that manufactures a plurality of products from a quantity of supplied material in a series of repeated cycles, includes a detector for detecting power consumption in a time period that includes at least the time needed for manufacturing all of the products that can be manufactured from a given quantity of supplied material, from the time at which the supply of the material to the apparatus commences to the time at which any remaining material is ejected, and delivers an output indicating power consumption per product by using the power consumption detected by the power detector and the number of products manufactured from the given quantity of supplied material. The device is thus capable of precisely calculating the electricity cost per product manufactured by an apparatus whose power consumption varies from one cycle of operation to another.

First claim

The invention claimed is:

1. A processing system for manufacturing products from a supplied unit of elongated material by cutting the unit of elongated material, said processing system comprising an automatic lathe that includes electrically-operated instruments related to manufacturing said products and that sequentially feeds and cuts the supplied unit of elongated material to produce a plurality of products therefrom, a material supplying device for sequentially supplying the unit of elongated material to the automatic lathe, control means for controlling the automatic lathe and the material supplying device, and a power consumption output device of the automatic lathe, said supplied unit of elongated material becoming shorter in length as said supplied unit is sequentially fed and cut, the power consumption output device comprising:
power detection means for detecting power consumption of the electrically-operated instruments or the whole automatic lathe during a predetermined processing operation wherein, from the beginning to the end of the processing operation, a supplied unit of elongated material is sequentially fed and cut to produce said plurality of products therefrom, and sequentially becomes shorter at least by an amount equal to the length of each product cut therefrom, and wherein the power consumed by said electrically-operated instruments, and by the whole automatic lathe, changes from one product to another as a result of the shortening of the length of said supplied unit of elongated material as each said product is cut therefrom; and
output means for calculating and outputting average electric energy consumption of the electrically-operated instruments or the whole automatic lathe per product manufactured with the processing operation from said supplied unit of elongated material, the calculation carried out by said output means being based on power consumption and a number of products, said power consumption being power consumption detected by the power detection means, that changes from one product to another as a result of the shortening of the length of said supplied unit of elongated material as said supplied unit is sequentially fed and cut, and said number of products being the number of products manufactured in said processing operation, wherein:
the power detection means detects power consumption of the whole automatic lathe or the electrically-operated instruments from the beginning to the end of a processing operation on a single supplied unit of said elongated material;
the output means calculates and outputs electric energy consumption of the electrically-operated instruments or the whole automatic lathe, per product manufactured from said single supplied unit of elongated material by using the power consumption detected by the power detection means and the number of products manufactured from the said single supplied unit of elongated material, and
said control means determines when a product can no longer be made from the remaining material in said supplied unit of elongated material, causes said power detection means to continue to detect said power consumption until a product can no longer be made from the remaining material in said supplied unit of elongated material, and, when it determines that a product can no longer be made from said remaining material, causes said power detection means to stop detecting power consumption and causes said automatic lathe to elect said remaining material.

2. The processing system according to claim 1 , wherein the electrically-operated instruments include supplying means for supplying said elongated material to the automatic lathe.

3. The power processing system according to claim 1 , wherein the power consumption output device comprises display means for displaying the power consumption per product.

4. The processing system according to claim 1 , including count means for counting the number of products manufactured from said single unit of elongated material.
