Abstract
Abstract Apparatus and method for picking up, transferring and depositing light flexible articles. The apparatus includes a driven rotary member having a plurality of tubular arms extending from circumferentially spaced portions of the member. The ends of these arms pass through a portion of a receptacle in which the articles are stored and suction is set up on these arms at their ends as moved through the receptacle to attract articles thereto. An air discharge blast is provided in the arms when the articles are to be released.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
Apparatus for pickIng up and transferring light articles comprising an open topped receptacle for the articles, a frame, a support arm extending upwardly from said frame, a support shaft, said support shaft being mounted on said support arm and extending downwardly towards the receptacle, a driven rotary carrier plate attached to said support shaft, a plurality of tubular arms extending from circumferentially spaced portions of said carrier plate and with their ends being positioned for passing through a portion of said receptacle in one part of their rotary movement, said rotary member with said tubular arms thereon being positioned above said receptacle, a stationary manifold disc extending about said support shaft and having an axial face, said axial face abuttingly engaging said rotary plate, a support bar connected to said frame and pivotally attached to said manifold, a suction supply attached to said manifold and an air pressure supply attached to another portion of said manifold so that as said carrier plate rotates, said arm ends are successively supplied with vacuum to carry an article thereby and then with air pressure to positively discharge the article thereby.
Claim 2
Dependent Claim
187 words
Apparatus for pickIng up and transferring light articles comprising an open topped receptacle for the articles, a frame, a support arm extending upwardly from said frame, a support shaft, said support shaft being mounted on said support arm and extending downwardly towards the receptacle, a driven rotary carrier plate attached to said support shaft, a plurality of tubular arms extending from circumferentially spaced portions of said carrier plate and with their ends being positioned for passing through a portion of said receptacle in one part of their rotary movement, said rotary member with said tubular arms thereon being positioned above said receptacle, a stationary manifold disc extending about said support shaft and having an axial face, said axial face abuttingly engaging said rotary plate, a support bar connected to said frame and pivotally attached to said manifold, a suction supply attached to said manifold and an air pressure supply attached to another portion of said manifold so that as said carrier plate rotates, said arm ends are successively supplied with vacuum to carry an article thereby and then with air pressure to positively discharge the article thereby.
Claim 3
Dependent Claim
67 words
Apparatus as in claim 1 where said support shaft is so positioned so that said rotary member is positioned to move said arms into said receptacle and then upwardly out of and above said receptacle and said discharge air pressure is applied thereto when said arms are elevated, the ends of said tubular arms being directed out of said receptacle when such discharge air pressure is applied.
Claim 4
Dependent Claim
18 words
Apparatus as in claim 1 wherein spring means press said manifold disc into engagement with said carrier plate.
Claim 5
Dependent Claim
222 words
Apparatus for picking up and transferring light articles comprising an open topped receptacle for the articles, a frame, a support arm extending upwardly from said frame, a support shaft, said support shaft mounted on said support arm and extending downwardly toward said receptacle at an inclination to a vertical axis, a driven rotary center member in said receptacle to support articles therein, said center member being on a shaft that is not aligned with said support shaft, a driven rotary carrier plate attached to said support shaft, a plurality of tubular arms extending from circumferentially spaced portions of said carrier plate and with their ends being positioned for passing through a portion of said receptacle in one part of their rotary movement, said rotary member with said tubular arms thereon being positioned above said receptacle, a stationary manifold disc extending about said support shaft and having an axial face, said axial face abuttingly engaging said rotary plate, a support bar connected to said frame and pivotally attached to said manifold, a suction supply attached to said manifold, and an air pressure supply attached to another portion of said manifold so that as said carrier plate rotates, said arm ends are successively supplied with vacuum to engage and carry an article thereby and then with air pressure to positively discharge the article thereby.
Claim 6
Dependent Claim
222 words
Apparatus for picking up and transferring light articles comprising an open topped receptacle for the articles, a frame, a support arm extending upwardly from said frame, a support shaft, said support shaft mounted on said support arm and extending downwardly toward said receptacle at an inclination to a vertical axis, a driven rotary center member in said receptacle to support articles therein, said center member being on a shaft that is not aligned with said support shaft, a driven rotary carrier plate attached to said support shaft, a plurality of tubular arms extending from circumferentially spaced portions of said carrier plate and with their ends being positioned for passing through a portion of said receptacle in one part of their rotary movement, said rotary member with said tubular arms thereon being positioned above said receptacle, a stationary manifold disc extending about said support shaft and having an axial face, said axial face abuttingly engaging said rotary plate, a support bar connected to said frame and pivotally attached to said manifold, a suction supply attached to said manifold, and an air pressure supply attached to another portion of said manifold so that as said carrier plate rotates, said arm ends are successively supplied with vacuum to engage and carry an article thereby and then with air pressure to positively discharge the article thereby.
Claim 7
Dependent Claim
34 words
Apparatus as in claim 4 wherein spring means and a rotary connection assembly press said manifold disc into engagement with said carrier plate and aid in engaging said carrier plate with said manifold disc.
