Abstract
Abstract Apparatus for storing articles including walls defining a bin enclosure having an opening for transporting articles therethrough, a support for supporting articles in an article storage region in the enclosure, and a source of pressurized particle-free air to the region to provide a higher pressure in the article storage region than outside of the enclosure. Also disclosed are an energy beam vision system that is carried by a transport system and interfaces with the walls and a controller that controls the transport mechanism in order to properly align the relative positions of the transport mechanism and the enclosure.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
Apparatus for storing articles comprising walls defining a bin enclosure having an opening for transporting articles therethrough, a support for supporting articles in an article storage region in said enclosure, a transport mechanism for transporting said articles into and out of said storage region, said transport mechanism having two arms that can engage said articles between them and are movable along an axis into and out of said storage region, an energy beam vision system carried by said transport mechanism that directs an energy beam along a path that is close to but spaced from an outer boundary of a properly located and oriented article in said article storage region, and means for determining if said beam is blocked by said article.
Claim 2
Dependent Claim
122 words
Apparatus for storing articles comprising walls defining a bin enclosure having an opening for transporting articles therethrough, a support for supporting articles in an article storage region in said enclosure, a transport mechanism for transporting said articles into and out of said storage region, said transport mechanism having two arms that can engage said articles between them and are movable along an axis into and out of said storage region, an energy beam vision system carried by said transport mechanism that directs an energy beam along a path that is close to but spaced from an outer boundary of a properly located and oriented article in said article storage region, and means for determining if said beam is blocked by said article.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said vision system includes a light beam source and detector that are carried by said transport mechanism, and further comprising a reflector supported by a said wall.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2 wherein said transport mechanism includes two arms for engaging an article-carrying carriers at its sides.
Claim 5
Dependent Claim
25 words
The apparatus of claim 3 wherein each said transport arm carries a said vision system, and there are two reflectors supported by a said wall.
Claim 6
Dependent Claim
30 words
The apparatus of claim 1 further comprising a source of particle-free air to said region to provide a higher pressure in said article storage region than outside of said enclosure.
Claim 7
Dependent Claim
24 words
The apparatus of claim 3 further comprising a plurality of said walls, supports, and sources of air to provide a plurality of said enclosures.
Claim 8
Dependent Claim
20 words
The apparatus of claim 6 wherein each said source of air includes a separate supply tube for each said enclosure.
Claim 9
Dependent Claim
18 words
The apparatus of claim 7 wherein said supply tubes are gently curving so as to avoid dead spaces.
Claim 10
Dependent Claim
145 words
Apparatus for storing articles comprising walls defining a bin enclosure having an opening for transporting articles therethrough, a support for supporting articles in an article storage region in said enclosure, a transport mechanism for transporting said articles into and out of said storage region, said transport mechanism having two arms that can engage said articles between them and are movable along an axis into and out of said storage region, a transverse vision system that is carried by said arms and passes an energy beam between the arms along a path that is transverse to said axis to detect the presence of objects between the arms, and means for sensing blocking of said beam as a function of position of said arms as said arms are removed from said storage region to determine if said article has been dragged after it has been dropped off.
Claim 11
Dependent Claim
145 words
Apparatus for storing articles comprising walls defining a bin enclosure having an opening for transporting articles therethrough, a support for supporting articles in an article storage region in said enclosure, a transport mechanism for transporting said articles into and out of said storage region, said transport mechanism having two arms that can engage said articles between them and are movable along an axis into and out of said storage region, a transverse vision system that is carried by said arms and passes an energy beam between the arms along a path that is transverse to said axis to detect the presence of objects between the arms, and means for sensing blocking of said beam as a function of position of said arms as said arms are removed from said storage region to determine if said article has been dragged after it has been dropped off.
Claim 12
Independent Claim
149 words
A method of placing an article at a desired location and in a desired orientation on a support in an article storage region comprising engaging said article with a transport mechanism that has two arms that are spaced from each other and engage said article in the space between said arms, said arms carrying a transverse vision system that passes an energy beam along a path between the arms to detect the presence of objects between the arms, moving said transport mechanism and engaged article along an axis that is transverse to said path into a position over said desired location, disengaging said article so as to place it on said support, and retracting said transport mechanism along said path and simultaneously sensing blocking of said beam as a function of position of said arms to determine if said article has been dragged after it has been dropped off.
Claim 13
Independent Claim
149 words
A method of placing an article at a desired location and in a desired orientation on a support in an article storage region comprising engaging said article with a transport mechanism that has two arms that are spaced from each other and engage said article in the space between said arms, said arms carrying a transverse vision system that passes an energy beam along a path between the arms to detect the presence of objects between the arms, moving said transport mechanism and engaged article along an axis that is transverse to said path into a position over said desired location, disengaging said article so as to place it on said support, and retracting said transport mechanism along said path and simultaneously sensing blocking of said beam as a function of position of said arms to determine if said article has been dragged after it has been dropped off.
Claim 14
Independent Claim
117 words
A method of placing an article at a desired location and in a desired orientation on a support in an article storage region comprising engaging said article with a transport mechanism that carries an energy beam vision system, moving said transport mechanism and engaged article into a position over said desired location, disengaging said article so as to place it on said support, retracting said transport mechanism, directing a beam of said energy beam vision system along a path that is close to but spaced from an outer boundary of a properly located and oriented article in said article storage region, and detecting whether said beam is intersected by said article, thereby indicating improper placement or orientation.
Claim 15
Independent Claim
117 words
A method of placing an article at a desired location and in a desired orientation on a support in an article storage region comprising engaging said article with a transport mechanism that carries an energy beam vision system, moving said transport mechanism and engaged article into a position over said desired location, disengaging said article so as to place it on said support, retracting said transport mechanism, directing a beam of said energy beam vision system along a path that is close to but spaced from an outer boundary of a properly located and oriented article in said article storage region, and detecting whether said beam is intersected by said article, thereby indicating improper placement or orientation.
