Abstract
Abstract An automatic freight stacking system for loading previously determined freight articles of various configurations (shapes, size, material, etc.) to be shipped, using a loading scheduler for determining a loading schedule on the basis of the existing various configurations of the freight articles, marshalling equipment for receiving the freight articles in a given order and delivering them in a predetermined order which is determined by the scheduler, a feeding conveyor for carrying the delivered freight articles and transporting means to the places of the respective loading means allocated by the loading scheduler, and the loading means for loading the carried freight articles on the transporting means in accordance with the scheduled operation sequence. In the case where the configurations of certain freight articles to be shipped are unknown before the arrival thereof, a reader is provided to read the dimensions of the freight articles upon arrival thereof and then the operator monitors through a display terminal the state of the articles and the state of the articles loaded on the transporting means and indicates the freight article to be loaded as well as the position to be loaded to the loading means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
An automatic freight stacking system comprising: loading scheduler means for determining respective loading positions of articles on a transporting means, the loading order of said articles, the allocation of a plurality of loading means and the preparation of an operation sequence for a plurality of freight articles of various configurations to be transported; marshalling means for receiving said freight articles in a given sequence and delivering said freight articles in a predetermined loading order; feeding means for supplying said freight articles from said marshalling means to the places of respective one of said plurality of loading means allocated to said freight articles, in dependence on the configurations thereof, by said loading scheduler means; conveyor means for moving said transporting means to the places of respective ones of said plurality of loading means allocated by said loading scheduler means; each of said plurality of loading means loading said freight articles allocated thereto in dependence on the configurations thereof on said transporting means in accordance with said operation sequence; and general control means receiving data from said loading scheduler means for controlling said marshalling, feeding, conveyor and plurality of loading means in a coordinated manner.
Claim 2
Dependent Claim
193 words
An automatic freight stacking system comprising: loading scheduler means for determining respective loading positions of articles on a transporting means, the loading order of said articles, the allocation of a plurality of loading means and the preparation of an operation sequence for a plurality of freight articles of various configurations to be transported; marshalling means for receiving said freight articles in a given sequence and delivering said freight articles in a predetermined loading order; feeding means for supplying said freight articles from said marshalling means to the places of respective one of said plurality of loading means allocated to said freight articles, in dependence on the configurations thereof, by said loading scheduler means; conveyor means for moving said transporting means to the places of respective ones of said plurality of loading means allocated by said loading scheduler means; each of said plurality of loading means loading said freight articles allocated thereto in dependence on the configurations thereof on said transporting means in accordance with said operation sequence; and general control means receiving data from said loading scheduler means for controlling said marshalling, feeding, conveyor and plurality of loading means in a coordinated manner.
Claim 3
Dependent Claim
110 words
An automatic freight stacking system according to claim 1, wherein said loading scheduler means includes data storing means for storing first data of various transporting means, second data of the freight articles to be transported, third data of disposition of said freight articles on said transporting means prepared on the basis of said first and second data, the order of loading said freight articles, data corresponding to the allocation of said plurality of loading means, and the operation sequences of each of said plurality of loading means in a tabulated form, said first and said second data being inputted to said loading scheduler means before starting the article loading operation.
Claim 4
Dependent Claim
130 words
An automatic freight stacking system according to claim 1, wherein said general control means includes a first memory for storing information of work order and loading pattern name supplied externally and information of work state supplied from said marshalling means; a second memory for storing information of the loading order, identification numbers of each loading means of said allocated plurality of loading means supplied from said loading scheduler means and information of loading state signaled from said plurality of loading means; a third memory for storing information of the work state supplied from said loading scheduler means; a fourth memory for storing inventory and shelf information supplied from said marshalling means; and a fifth memory for storing information of supply state inputted from said marshalling means and said feeding means.
Claim 5
Dependent Claim
79 words
An automatic freight stacking system according to claim 1, wherein said loading scheduler means is so arranged as to previously determine the loading pattern, the loading order and the allocation of each one of said plurality of loading means such that said plurality of loading means destined for handling respective articles in dependence on the configurations thereof and arrayed on a line can load the allocated articles in the order in which said plurality of loading means are arrayed.
Claim 6
Dependent Claim
184 words
In a shipping system in which freight articles are loaded on a transporting means after determining the respective configurations of the freight articles and the number of said freight articles, an automatic freight loading system, comprising: means for reading the dimensions of each of said freight articles; means for stocking temporarily said freight articles; graphic display terminal means; means for loading the freight articles on said transporting means; and a general control means for operatively controlling the above mentioned reading, temporarily stocking, display and loading means in a coordinated manner, wherein the freight articles having the dimensions read by said reader means are temporarily stocked in said stock means, the state of residual freight articles in said means for stocking temporarily said freight articles and the disposition state of the freight articles on said transporting means being monitored through said graphic display terminal means, said loading means being furnished with information of the freight articles to be loaded and the positions on said transporting means at which said freight articles are to be positioned, for thereby loading said freight articles on said transporting means.
Claim 7
Dependent Claim
184 words
In a shipping system in which freight articles are loaded on a transporting means after determining the respective configurations of the freight articles and the number of said freight articles, an automatic freight loading system, comprising: means for reading the dimensions of each of said freight articles; means for stocking temporarily said freight articles; graphic display terminal means; means for loading the freight articles on said transporting means; and a general control means for operatively controlling the above mentioned reading, temporarily stocking, display and loading means in a coordinated manner, wherein the freight articles having the dimensions read by said reader means are temporarily stocked in said stock means, the state of residual freight articles in said means for stocking temporarily said freight articles and the disposition state of the freight articles on said transporting means being monitored through said graphic display terminal means, said loading means being furnished with information of the freight articles to be loaded and the positions on said transporting means at which said freight articles are to be positioned, for thereby loading said freight articles on said transporting means.
