Abstract

Abstract A program-controlled article-transfer robot is adapted to load a pallet automatically with cartons of various sizes without dependence on a lengthy control program identifying the position of every carton in each of the rows and at each of the levels of the load. At the start, the robot is taught to load only a single carton on the pallet, ordinarily at one corner and at the surface of the pallet. When the robot goes through its routine for loading the first carton, it picks up a carton at a supply point, and it measures the dimensions of the carton. Subsequent cartons are loaded in successive rows and in successive levels automatically, in dependence on the first-carton loading coordinates, on the carton measurements, on the pallet size, and on the height limit of the load. The control apparatus prevents any projection of cartons outside the pallet outline and it also limits projection of cartons at upper levels beyond the nextlower level to within limits to insure stability. The procedure is also operable to create a complete program automatically, so that subsequent robot operations can load and unload pallets under program control.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 179 words
Apparatus for transferring articles to a receiving area including an article transfer mechanism having an article holder, means for operating the article holder through desired paths in space, control means including means for storing a program for controlling said operating means to execute repeatedly a basic sequence of operations which includes seizing an article at a pick-up location, transferring the article to a particular location in the receiving area, releasing the article, and returning the article holder to a pick-up location, said article holder having article-calipering means cooperable with an article to be transferred to the receiving location for measuring at least one dimension thereof, and means responsive to said calipering means for modifying the control of the operating means by that part of said stored program that relates to the motion of the article holder at the receiving area in successive program cycles to transfer successive articles automatically to successive positions in said receiving area displaced from said particular location in the receiving area by distances that are a function of the measurement output of the article-calipering means.
Claim 2
Dependent Claim 179 words
Apparatus for transferring articles to a receiving area including an article transfer mechanism having an article holder, means for operating the article holder through desired paths in space, control means including means for storing a program for controlling said operating means to execute repeatedly a basic sequence of operations which includes seizing an article at a pick-up location, transferring the article to a particular location in the receiving area, releasing the article, and returning the article holder to a pick-up location, said article holder having article-calipering means cooperable with an article to be transferred to the receiving location for measuring at least one dimension thereof, and means responsive to said calipering means for modifying the control of the operating means by that part of said stored program that relates to the motion of the article holder at the receiving area in successive program cycles to transfer successive articles automatically to successive positions in said receiving area displaced from said particular location in the receiving area by distances that are a function of the measurement output of the article-calipering means.
Claim 3
Dependent Claim 94 words
Article transfer apparatus in accordance with claim 1, wherein said calipering means includes two pairs of jaws operable symmetrically toward a common center for making mutually perpendicular measurements of the length and width of an article to be transferred, and wherein said apparatus includes means responsive to the calipering means for deriving halves of said measurements, said modifying means being responsive to said halfmeasurement deriving means for transferring the calipered article to a location in said receiving area displaced in mutually perpendicular directions from said particular location by said halves of said calipered measurements.
Claim 4
Dependent Claim 139 words
Apparatus for transferring an article from a pick-up location to a receiving location, including articletransfer mechanism having an article holder, means for operating the article holder through desired paths in space, control means for causing said operating means to cause the article holder to pick up an article at the receiving location, transfer it to the receiving location and release the article centered at a particular location, said article holder having article-calipering means including jaws operable symmetrically toward the center of the article holder and said apparatus including means responsive to said calipering means for deriving half of said one dimension, and means responsive to said half-dimension deriving means for modifying the control effected by said control means for transferring the article to a location whose center is displaced from said particular location by one-half of the calipered dimension.
Claim 5
Dependent Claim 139 words
Apparatus for transferring an article from a pick-up location to a receiving location, including articletransfer mechanism having an article holder, means for operating the article holder through desired paths in space, control means for causing said operating means to cause the article holder to pick up an article at the receiving location, transfer it to the receiving location and release the article centered at a particular location, said article holder having article-calipering means including jaws operable symmetrically toward the center of the article holder and said apparatus including means responsive to said calipering means for deriving half of said one dimension, and means responsive to said half-dimension deriving means for modifying the control effected by said control means for transferring the article to a location whose center is displaced from said particular location by one-half of the calipered dimension.
Claim 6
Dependent Claim 166 words
