In a production line for producing color picture tubes, a conveyor system for conveying panels P and masks M between a shadow mask demounting or mounting apparatus 6, 7 and a processing apparatus 2 having downwardly directed panel carrier head 4 and upwardly directed mask table 5. The system 8, 9 includes a mask transfer device 13 and a panel transfer device 30 movably carried by upper rail devices 11, 12, and a panel traverser 41 carried by a lower rail device 40. The convey of the mask is performed solely by the mask transfer device 13, while the panel is conveyed by the panel transfer device 30 and the panel traverser 41.

1. A conveyor system for conveying panels and shadow masks between a processing apparatus of the type having at least a table and a carrier head arranged in pair adapted to be moved along a predetermined path, said table being accessible from the upper side while said carrier head is accessible from the lower side, and a shadow mask demounting or mounting apparatus disposed adjacent to said processing apparatus, said conveyor system comprising: a mask conveyor means for conveying a shadow mask between the table positioned at a first predetermined position and a second predetermined position on said shadow mask mounting or demounting apparatus; a first panel conveyor means for conveying said panel between said carrier head positioned at a third predetermined position and a fourth predetermined position spaced from said third predetermined position; and a second panel conveyor means for conveying said panel between said fourth predetermined position and a fifth predetermined position on said shadow mask demounting or mounting apparatus. 2. A conveyor system as claimed in claim 1, wherein said mask conveyor means includes a mask conveyor rail device extending substantially above said first predetermined position and said second predetermined position, and a mask transfer device movably carried by said mask conveyor rail device, said mask transfer device having a mask holder movable up and down. 3. A conveyor system as claimed in claim 1 or 2, wherein said first panel conveyor means includes a panel conveyor lower rail device extending substantially beneath said third predetermined position and said second predetermined position, and a panel traverser movably carried by said panel conveyor lower rail device, said panel traverser having a panel holder movable up and down. 4. A conveyor system as claimed in claim 2, wherein said first panel conveyor means includes a panel conveyor lower rail device extending substantially beneath said third predetermined position and said fourth predetermined position, and a panel traverser movably carried by said panel conveyor lower rail device, said panel traverser having a panel holder movable up and down, and wherein said second panel conveyor means includes a panel conveyor upper rail device extending substantially above said fourth predetermined position and said fifth predetermined position, and a panel transfer device movably carried by said panel conveyor upper rail device, said panel transfer device having a panel holder movable up and down. 5. A conveyor system as claimed in claim 4, wherein said mask conveyor rail device and said panel conveyor upper rail device are arranged along a line, while said panel conveyor lower rail device is disposed substantially beneath said mask conveyor rail device and said mask conveyor upper rail device. 6. A conveyor system as claimed in claim 5, wherein said panel conveyor lower rail device extends through the area beneath said shadow mask demounting or mounting apparatus. 7. A conveyor system as claimed in claim 4, wherein said panel conveyor lower rail device extends at a lateral side of said shadow mask demounting or mounting apparatus. 8. A conveyor system as claimed in claim 7, wherein said panel conveyor upper rail device extends substantially at a right angle to said mask conveyor device. 9. A conveyor system as claimed in any one of claims 1, 2, 4, 5, 6, 7 and 8, wherein said mask demounting or mounting apparatus is adapted to perform only the demounting of said shadow mask from said panel, while said mask conveyor means is adapted to perform only the convey of said mask from said shadow mask demounting or mounting apparatus to said table of said processing apparatus, whereas said first and second panel conveyor means in cooperation perform only the convey of said panel from said mask demounting or mounting apparatus to said carrier head of said processing apparatus. 10. A conveyor system as claimed in any one of claims 1, 2, 4, 5, 6, 7 and 8, wherein said mask conveyor means is adapted to perform only the convey of said shadow masks from said table to said mask demounting or mounting apparatus, while said first and second panel conveyor means in cooperation perform only the convey of said panels from said carrier head to said shadow mask demounting or mounting apparatus, whereas said mask demounting or mounting apparatus is adapted to perform only the mounting of said shadow mask in said panel. 11. A conveyor system as claimed in any one of claims 2, 4, 5, 6, 7 and 8, characterized by further comprising transfer means including rails extending substantially at the same level as said mask conveyor rail means substantially at a right angle to the latter, a transfer movably carried by said rails, and a panel holder carried vertically movably by said transfer, said transfer means being adapted to transfer said panel with said shadow mask mounted therein to and from said mask demounting or mounting apparatus.
