Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
A stacking machine for parallelepiped-shaped objects comprising a load-bearing frame; a feed roller bed adjoining said frame; a receiving table mounted on said frame in line with said feed roller bed to provide a continuation thereof, whereby objects moving along said feed roller bed will be fed onto said receiving table; an accumulating table slidably supported on said frame for horizontal movement and said accumulating table being at a lower level than said receiving table and adjacent thereto; pusher means mounted on said frame for moving the objects from said receiving table onto said accumulating table; a conveyor mounted on said frame under said accumulating table for delivering an empty container therebelow; means for transferring the objects moved onto said accumulating table into said container; said transferring means including engagement means supported on said frame above the accumulating taBle for engaging and supporting the objects; means associated with said engagement means for vertically lowering and raising same, whereby when objects are being supported by said engagement means and the accumulating table has been moved horizontal the objects can be lowered into the container therebelow, and said container, when full, can be moved along said conveyor and another empty container delivered thereat.
Claim 2
Dependent Claim
201 words
A stacking machine for parallelepiped-shaped objects comprising a load-bearing frame; a feed roller bed adjoining said frame; a receiving table mounted on said frame in line with said feed roller bed to provide a continuation thereof, whereby objects moving along said feed roller bed will be fed onto said receiving table; an accumulating table slidably supported on said frame for horizontal movement and said accumulating table being at a lower level than said receiving table and adjacent thereto; pusher means mounted on said frame for moving the objects from said receiving table onto said accumulating table; a conveyor mounted on said frame under said accumulating table for delivering an empty container therebelow; means for transferring the objects moved onto said accumulating table into said container; said transferring means including engagement means supported on said frame above the accumulating taBle for engaging and supporting the objects; means associated with said engagement means for vertically lowering and raising same, whereby when objects are being supported by said engagement means and the accumulating table has been moved horizontal the objects can be lowered into the container therebelow, and said container, when full, can be moved along said conveyor and another empty container delivered thereat.
Claim 3
Dependent Claim
69 words
A stacking machine as claimed in claim 1, wherein said engagement means comprises four arms arranged in pairs in two parallel vertical planes; the ends of said arms are interconnected by two pairs of bars; one pair of said bars for engaging and supporting the objects on the accumulating table and the other pair of said bars for connecting the arms to one another, and to the lowering means.
Claim 4
Dependent Claim
51 words
A stacking machine as claimed in claim 1 wherein the lowering means includes a counterweight whose mass is smaller than that of the engagement means loaded with said objects but greater than that of the empty engagement means for returning the latter to the initial position after the objects are released.
Claim 5
Dependent Claim
51 words
A stacking machine as claimed in claim 2 wherein the lowering means includes a counterweight whose mass is smaller than that of the engagement means loaded with said objects but greater than that of the empty engagement means for returning the latter to the initial position after the objects are released.
Claim 6
Dependent Claim
25 words
A stacking machine as claimed in claim 3 wherein the counterweight is provided with a shock absorber for uniform vertical movement of the engagement means.
Claim 7
Dependent Claim
66 words
A stacking machine as claimed in claim 5 wherein the shock absorber comprises at least one vertically mounted hydraulic cylinder whose piston rod is rigidly connected with the counterweight and said cylinder having spaces under and above the piston which intercommunicate through a bypass pipe whereby the speed of the counterweight may be adjusted by changing the resistance of the fluid flow through said bypass pipe.
