<p>1,090,537. Moulding machines. E.BUHRER. June 3, 1965 [June 5, 1964], No. 23823/65. Heading B3F. Apparatus for assembling mould parts to form completed mould boxes comprises two driven conveyers A and B carrying respective upper and lower mould parts 1 and 2 to be assembled. A framed structure 50 overlies the two conveyers and incorporates means for transferring the upper mould parts 1 from conveyer A into position on the lower mould part 2 on the conveyer B in time synchronized relationship without arresting the conveyer B. The transferring means comprises a movable member 3 displaceable parallel to the conveyer B and a truck 5 movable transversely to the conveyer B. The truck carries a lifting device 9 for gripping and lifting the upper mould parts 1 during the transferring operation. The truck 5, member 3 and lifting device 9 are all fluid actuated. The lifting device incorporates centring means to effect correct and accurate location of the device over the mould and further aligning means is provided to accurately locate the mould parts for assembly. Mechanical drive means 25 to 28 attached to the conveyer driving source effects the operation of a lost motion device 41, 42 associated with the piston rod 40 of the cylinder 43 which actuates the movable member 3. This lost motion action permits the lifting device to engage the upper mould box parts while movable member 3 is stationary. In an alternative embodiment the reciprocation of the member 3 is effected continuously under which arrangement the upper mould parts are engaged by the lifting device whilst moving. This is necessary when the conveyers A and B are arranged parallel to one another and move in opposite directions. The sequence of operations may be effected automatically and more than one transfer device may be incorporated.</p> |
