Appl. No.:

7/238831

Inventors:

Harold S. Burt - Kansas City KS
Benjamin P. Difalco - Overland Park KS

Assignee:

Mid-West Conveyor Co., Inc. - Kansas City KS

International Classification:

B61J 300
B61B 1300
B65G 3700

US Classification:

104 88

Abstract:

A conveyor system includes a power and free section transporting product carriers on power and free type trolleys and a monorail section transporting utility carriers about a fixed loop. The monorail system is connected to the power and free section to receive and transport the trolleys with the product carriers interspaced between the utility carriers.

Inventors:

Gareth D. Summa - Riverside MO
George K. Reed - Kansas City KS
Harold S. Burt - Kansas City KS

Assignee:

Mid-West Conveyor Company, Inc. - Kansas City KS

International Classification:

B65G 106

US Classification:

414280

Abstract:

An apparatus for selectively storing a thin tray or sheet in an elongate storage location, and retrieving trays therefrom, includes a tray extractor and a transport assembly. The tray extractor comprises a tray engagement mechanism and a tray linear movement actuator. The tray engagement mechanism operates as a hand to selectively grip or release trays which are being handled by the apparatus. The tray linear movement actuator acts as an arm to position the tray engagement mechanism and, when operated, to move an engaged tray. The tray linear movement actuator comprises a linear movement link and pulley arrangement which moves an engaged tray along a linear path of motion, and which maintains the tray engagement mechanism in a selected orientation with respect to that path of movement. The tray engagement mechanism comprises an X-shaped scissors mechanism having a plurality of jaws thereon. Scissors motion of the mechanism opens and closes the pairs of jaw members to selectively engage or disengage a tray.

International Classification:

B65G 100

US Classification:

414275

Abstract:

An automatic storage and retrieval system including a storage bin, having a mechanism for positioning a vehicle at the storage bin including a rough positioning mechanism with an encoder having a rotatable member which rotates through an arc less than a complete revolution in response to movement of the vehicle and generates a signal with a different value at each of various member positions which correspond to respective vehicle rough position zones. A control device receives the signal and selectively causes the vehicle to move to a rough position zone at the storage bin. A fine positioning mechanism repositions the vehicle within a particular position zone after rough positioning and utilizes a light source and photoelectric sensor mounted on the vehicle for detecting a target mounted in a fixed relation with respect to the storage bin. The control mechanism receives an electrical signal generated by the photoelectric sensor and causes the vehicle to stop at the fine position location at the storage bin. A high-low positioning device selectively lowers and raises a carriage including a retrieval apparatus such as a fork assembly within the bin.
