Abstract

Abstract A pig-piling device comprising a first conveyor delivering pigs to a manipulator and onto an intermediate support. An accumulating table is located after the intermediate support in the direction of regular operation and is mounted with provision for vertical movement for connecting the pig it carries with the pig located on the intermediate support. A second conveyor is installed below the accumulating table which shifts the interlocked pigs from the intermediate support onto the accumulating table. The rows of pigs are carried and formed into a pile by a grip mounted on a driven trolley.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 362 words
A device for piling metal pigs comprising: a supporting frame; a first conveyor means consisting of a carriage moving on guides, and mounted between skids for shifting metal pigs and provided on its sides with a first set of coaxial articulated spring-loaded twinned pig pushers; first drive means for reciprocating the carriage of said first conveyor means; manipulator means rotatably mounted on said supporting frame for turning around a horizontal axis and consisting of a drum having a through opening for receiving the carriage of said first conveyor means containing a pig; second drive means for turning the manipulator means around its horizontal axis, said second drive means being secured on said supporting frame; an intermediate support for receiving pigs having interlocking elements from said manipulator means and secured on said supporting frame, level with the skids of said first conveyor means; an accumulating table for accumulating pigs in rows and interlocked with their respective interlocking elements, said table being pivotally secured on said supporting frame for vertical movement to three positions required for the engagement of the interlocking elements of said pig located on said intermediate support with counterpart interlocking elements on the pig located on said accumulating table to form said rows; third drive means mounted on said supporting frame for moving said accumulating table vertically to said three positions; a second conveyor means consisting of a carriage which moves on guides secured on said supporting frame below the level of said intermediate support and said accumulating table, and being provided on its sides with a second set of coaxial articulated spring-loaded twinned pig pushers; fourth drive means for reciprocating the carriage of said second conveyor means; a pileforming table located after said accumulating table in the direction of regular operation of the device; fifth drive means for causing vertical movement of said pile-forming table; an armtype grip mounted on a driven trolley which is installed in the guides secured on said supporting frame above said accumulating and pile-forming tables, said grip repeatedly picking up the pigs formed in a row on said accumulating table, and carrying and placing them on said pile-forming table to form a pile of pigs.
Claim 2
Independent Claim 362 words
A device for piling metal pigs comprising: a supporting frame; a first conveyor means consisting of a carriage moving on guides, and mounted between skids for shifting metal pigs and provided on its sides with a first set of coaxial articulated spring-loaded twinned pig pushers; first drive means for reciprocating the carriage of said first conveyor means; manipulator means rotatably mounted on said supporting frame for turning around a horizontal axis and consisting of a drum having a through opening for receiving the carriage of said first conveyor means containing a pig; second drive means for turning the manipulator means around its horizontal axis, said second drive means being secured on said supporting frame; an intermediate support for receiving pigs having interlocking elements from said manipulator means and secured on said supporting frame, level with the skids of said first conveyor means; an accumulating table for accumulating pigs in rows and interlocked with their respective interlocking elements, said table being pivotally secured on said supporting frame for vertical movement to three positions required for the engagement of the interlocking elements of said pig located on said intermediate support with counterpart interlocking elements on the pig located on said accumulating table to form said rows; third drive means mounted on said supporting frame for moving said accumulating table vertically to said three positions; a second conveyor means consisting of a carriage which moves on guides secured on said supporting frame below the level of said intermediate support and said accumulating table, and being provided on its sides with a second set of coaxial articulated spring-loaded twinned pig pushers; fourth drive means for reciprocating the carriage of said second conveyor means; a pileforming table located after said accumulating table in the direction of regular operation of the device; fifth drive means for causing vertical movement of said pile-forming table; an armtype grip mounted on a driven trolley which is installed in the guides secured on said supporting frame above said accumulating and pile-forming tables, said grip repeatedly picking up the pigs formed in a row on said accumulating table, and carrying and placing them on said pile-forming table to form a pile of pigs.
Claim 3
Dependent Claim 72 words
A pig-piling device according to claim 1 wherein said third drive means of said accumulating table is made in the form of a cylinder having a movable element and secured to said supporting frame, the movable element of said cylinder carrying a three-step guide templet which contacts a roller means secured on the forward operating section of said accumulating table the rearward operating section of which is articulated to said supporting frame.
Claim 4
Dependent Claim 91 words
A pig-piling device according to claim 1 wherein said cylinder rod of the carriage drive of said second conveyor means has a stop fork with an electromagnetic drive mounted on said supporting frame, said drive withdrawing said stop fork from said rod for forming a lower row of the pile of pigs consisting of pigs whose pouring sides are directed upward and putting said stop fork on said rod for forming all the subsequent rows of the pile wherein every other pig is turned with the pouring side thereof facing downwards.
Claim 5
Dependent Claim 78 words
A pig-piling device according to claim 3 wherein the length of the section of said stop fork which limits the stroke of said carriage drive of said second conveyor means is equal to the difference between the center distance of two adjacent pigs in a row located with their pouring sides up and the center distance of two adjacent pigs in a row in which one of the adjacent pigs is turned with its pouring side facing downward.
Claim 6
Dependent Claim 115 words
A pig-piling device according to claim 1 wherein each pusher of a first pair of said second set of pushers taken in the direction of regular operation of the dEvice, on the carriage of said second conveyor means has two projections whose shape and dimensions provide for the interaction of one of these projections with the inclined side surface of a pig whose pouring side faces upward while the other projection interacts with the inclined side surface of a pig whose pouring side faces downward, and ensures the same distance between the axis of fastening of said pushers and the geometrical axes of the pigs, both non-turned and turned with their pouring side facing downwards.
Claim 7
Dependent Claim 105 words
A pig-piling device according to claim 1 wherein the drum of said manipulator means has a through opening whose upper and lower sides are provided with skids located level with the skids of said first conveyor means for carrying a pig and allowing passage between them of the carriage of said first conveyor means, wherein arc-shaped baffles are located under said drum for keeping the pigs from falling therefrom under rotation thereof and wherein said drum is provided with a reversible drive for turning the drum through 180* around a longitudinal axis, said drive comprising a cylinder interacting with a rack and a gear wheel.
