Abstract
Abstract An automatic transport system comprising a main conveyor for transporting containers or pallets which are provided with memory elements for identification and on which workpieces are stacked to receive an assembling or machining operation. A plurality of sub-conveyers are connected to the main conveyer for effecting the assembling or machining operations on the workpieces. The sub-conveyers are intermittently driven in succession to completely synchronize the working operations, while the main conveyer is periodically and freely driven independently of the sub-conveyers under the control of a computer. Thereby conventional accumulation or jamming of pallets caused by defects in the automatic assembling or machining devices or by defectively processed workpieces can be completely eliminated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
An automatic transport system comprising a main conveyer for transporting containers each with a plurality of pallets stacked therein and on which are loaded workpieces to be processed, a plurality of sub-conveyers disposed along said main conveyer in predetermined spaced relation for transporting said pallets delivered from said containers at an intersection location of said two conveyers and for returning the pallets back to the main conveyer after the workpieces have been processed along said subconveyer, and means for transporting said pallets from main conveyer to the sub-conveyers, said means including a first positioning means for positioning and stopping said containers on the main conveyer, pushing means for pushing the pallets stacked in the containers stopped by said positioning means one by one so as to transfer the pallets to the sub-conveyers and second positioning means for effecting a stopping operation of a proceeding container at the outlet end of the sub-conveyer to stack the pallets loaded with the processed workpieces therein.
Claim 2
Dependent Claim
162 words
An automatic transport system comprising a main conveyer for transporting containers each with a plurality of pallets stacked therein and on which are loaded workpieces to be processed, a plurality of sub-conveyers disposed along said main conveyer in predetermined spaced relation for transporting said pallets delivered from said containers at an intersection location of said two conveyers and for returning the pallets back to the main conveyer after the workpieces have been processed along said subconveyer, and means for transporting said pallets from main conveyer to the sub-conveyers, said means including a first positioning means for positioning and stopping said containers on the main conveyer, pushing means for pushing the pallets stacked in the containers stopped by said positioning means one by one so as to transfer the pallets to the sub-conveyers and second positioning means for effecting a stopping operation of a proceeding container at the outlet end of the sub-conveyer to stack the pallets loaded with the processed workpieces therein.
