Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
An apparatus for the extraction, stacking and discharge, as they are manufactured, of hollow articles such as cups, jars and similar packaging articles produced by moulding synthetics material, comprising in combination extraction means having suction means able to grasp the articles released from the mould, of changing the orientation of the articles and of depositing the articles on a receiving plate in a condition in which they are partially inserted in each other, stacker means having an alternating motion arranged in such a way as to axially push back the article previously deposited on the plate by the extraction means in order to fully insert the article in the stack which is simultaneously moved back and discharge means comprising retractable abutments associated with drive means for longitudinal motion with a view to displacing the stacks obtained longitudinally when the latter comprise a pre-determined number of articles.
Claim 2
Independent Claim
146 words
An apparatus for the extraction, stacking and discharge, as they are manufactured, of hollow articles such as cups, jars and similar packaging articles produced by moulding synthetics material, comprising in combination extraction means having suction means able to grasp the articles released from the mould, of changing the orientation of the articles and of depositing the articles on a receiving plate in a condition in which they are partially inserted in each other, stacker means having an alternating motion arranged in such a way as to axially push back the article previously deposited on the plate by the extraction means in order to fully insert the article in the stack which is simultaneously moved back and discharge means comprising retractable abutments associated with drive means for longitudinal motion with a view to displacing the stacks obtained longitudinally when the latter comprise a pre-determined number of articles.
Claim 3
Dependent Claim
52 words
An apparatus according to claim 1, wherein the extraction means comprises a hollow shaft, the internal space of which is connected to a source of suction and to a plurality of radial suction means intended to be brought into the immediate vicinity of the wall of the articles released fRom the mould.
Claim 4
Dependent Claim
56 words
An apparatus according to claim 2, wherein a transverse reciprocating motion is imparted to the hollow shaft and comprising a radial crank engaged in a profiled ramp in such a way as to cause said shaft to pivot during its displacement, the suction effect ceasing when this shaft is at the end of its return stroke.
Claim 5
Dependent Claim
38 words
An apparatus according to claim 3 wherein bearings supporting the hollow shaft are supported by slides mounted on horizontal guides, these slides being connected to each other by a transverse stirrup to which the control member is secured.
Claim 6
Dependent Claim
46 words
An apparatus according to claim 2, wherein the internal space of the hollow shaft is connected to the atmosphere through a rocking valve controlled by a stationary rod which bears against the aforesaid valve when the hollow shaft arrives at the end of its return stroke.
Claim 7
Dependent Claim
36 words
An apparatus according to claim 1, wherein the stacking means comprises a swinging arm integral with a shaft on which is keyed a crank controlled by the vertical displacement of the moving part of the mould.
Claim 8
Dependent Claim
38 words
An apparatus according to claim 1, wherein each of the retractable abutments of the discharge means is constituted by a moving part of a pneumatic jack, which part is engaged in a longitudinal groove of the receiving plate.
Claim 9
Dependent Claim
30 words
An apparatus according to claim 7 wherein the pneumatic jacks are supported by a moving cross member, provided in the manner of a carriage controlled longitudinally in its reciprocating motion.
Claim 10
Dependent Claim
47 words
An apparatus according to claim 7, wherein the retractable abutments and the means for longitudinal motion which are associated with them are placed under the control of a counting mechanism actuated at the time of each of the reciprocating strokes of the moving part of the mould.
