Abstract
Abstract An article transferring apparatus for transferring articles between various types of conveyors, such as through a threedimensional route. The apparatus includes a device for picking up an article as carried on a first conveyor, which device is mounted on a carriage movable substantially parallel to a second conveyor. The carriage has means associated therewith for moving the article laterally toward the second conveyor and for depositing same on the second conveyor when the carriage and the second conveyor are moving at substantially the same speed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
69 words
An apparatus according to claim 1, wherein said article holding means includes a support member movably mounted on said second carriage means for movement along said third path, said support member having article engaging means mounted thereon, and third drive means coacting between said second carriage means and said support member for causing reciprocating movement of said support member relative to said second carriage means along said third path.
Claim 2
Dependent Claim
124 words
An apparatus according to claim 2, wherein said first drive means includes an extendible and contractible fluid pressure cylinder connected between a frame and said first carriage means for causing reciprocation of said first carriage means along said first path, wherein said second drive means includes an extendible and contractible fluid pressure cylinder drivingly connected between said first and second carriage means for causing reciprocating movement of said second carriage means relative to said first carriage means along said second path, and wherein said third drive means includes an extendible and contractible fluid pressure cylinder drivingly connected between said second carriage means and said support member for causing reciprocating movement of said support member relative to said second carriage means along said third path.
Claim 3
Dependent Claim
25 words
An apparatus according to claim 2, wherein said article engaging means includes a pair of relatively movable article engaging elements mounted on said support member.
Claim 4
Dependent Claim
40 words
An apparatus according to claim 4, wherein said article engaging means includes a drive device connected to said article engaging element for causing rotation thereof and of the article mounted thereon about an axis substantially transverse to said third path.
Claim 5
Dependent Claim
109 words
An apparatus according to claim 2, further including detecting means mounted on said first carriage means and including a sensing portion disposed for coaction with said conveying device for detecting same, said detecting means including means for sensing the relative speed between said section of said conveying device and said first carriage means and for emitting a signal which is approximately proportional to said relative speed and a control unit operatively controlled by the signal emitted from said detecting means, said control unit controlling said first drive means for causing said first carriage means and said section of said conveyor means to be moved at substantially the same speed.
Claim 6
Dependent Claim
45 words
An apparatus according to claim 6, wherein said detecting means includes potentiometer means associated with said sensing portion for emitting a signal, the position of said sensing portion relative to said potentiometer means being determinative of the magnitude of the signal generated by said potentiometer.
Claim 7
Dependent Claim
79 words
An apparatus according to claim 7, wherein said potentiometer comprises a ringlike resistor, and wherein said sensing portion includes a leverlike element associated with said ringlike resistor and disposed for rotation relative thereto, said leverlike element being positioned for contacting a part of said conveying device whereby relative speed between said conveying device and said first carrier means causes said leverlike element to be rotated relative to said ringlike resistor to vary the signal emitted by said detecting device.
Claim 8
Dependent Claim
43 words
An apparatus according to claim 6, wherein said first drive means includes fluid pressure cylinder means connected to said first carriage means for reciprocating same, and said control unit comprising servo-valve means for controlling the flow of pressure fluid to said cylinder means.
Claim 9
Dependent Claim
116 words
An apparatus according to claim 1, including a frame having a first stationary guide track extending therealong and defining said first path, said first carriage means being supported for linear movement along said first guide track, said first carriage means in turn having a second elongated guide track fixedly mounted thereon and extending in a direction substantially perpendicular to said first guide track, said second guide track defining said second path with said second path being substantially perpendicular to said first path, said second path also extending in a direction toward the direction of travel of said section of said conveying device, and said third path being substantially perpendicular to both said first and second paths.
