Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
A device for automatically reading bar-codes disposed on at least one side of an article, said device comprising: a sliding plane whereon articles provided with a bar-code are advanced; a conveyor belt having a dragging section with means for receiving and advancing articles along the sliding plane in a direction of advancement, said means for receiving and advancing including a plurality of windows consecutively aligned in the direction of advancement and defining openings within the conveyor belt, each window opening being defined by at least two linearly extending orientating edges arranged to intersect and form a right angle whose vertex is pointed opposite to the advancement direction, and at least one readout station having at least one laser beam read head arranged to read the bar-codes applied on articles advancing along the slide plane, wherein articles having a bar-code disposed on at least one side of the article are received inside one of the plurality of windows so that the at least one side of the article lays parallel to the sliding plane and as the article is advanced towards the readout station, two orthogonal sides of the article are placed in abutment with the orientating edges, so that the article approaches the readout station in a prefixed orientation.
Claim 2
Independent Claim
209 words
A device for automatically reading bar-codes disposed on at least one side of an article, said device comprising: a sliding plane whereon articles provided with a bar-code are advanced; a conveyor belt having a dragging section with means for receiving and advancing articles along the sliding plane in a direction of advancement, said means for receiving and advancing including a plurality of windows consecutively aligned in the direction of advancement and defining openings within the conveyor belt, each window opening being defined by at least two linearly extending orientating edges arranged to intersect and form a right angle whose vertex is pointed opposite to the advancement direction, and at least one readout station having at least one laser beam read head arranged to read the bar-codes applied on articles advancing along the slide plane, wherein articles having a bar-code disposed on at least one side of the article are received inside one of the plurality of windows so that the at least one side of the article lays parallel to the sliding plane and as the article is advanced towards the readout station, two orthogonal sides of the article are placed in abutment with the orientating edges, so that the article approaches the readout station in a prefixed orientation.
Claim 3
Dependent Claim
71 words
A device according to claim 1, further comprising means for discharging articles on the sliding plane having at least one loading station provided with at least one routing chute extending from said sliding plane at an inclined angle and being arranged over the dragging section of said belt, said at least one chute having at least, at its lower end, an axis orientated in parallel with one of said orientating edges.
Claim 4
Dependent Claim
38 words
A device according to claim 1, wherein said readout station comprises at least two upper read heads arranged over the conveyor belt, each head being arranged to read a bar-code parallelly orientated to one of said orientating edges.
Claim 5
Dependent Claim
46 words
A device according to claim 1, wherein said readout station comprises at least two lower read heads disposed beneath the sliding plane and arranged to read, through a transparent part of the sliding plane itself, a bar code parallelly orientated to one of said orientating edges.
Claim 6
Dependent Claim
30 words
A device according to claim 1, further comprising, disposed along each said orientating edges, a plurality of sliding rollers, each swivellingly connected to the conveyor belt about a vertical axis.
Claim 7
Dependent Claim
67 words
A device according to claim 1, further comprising, downstream from the readout station, an operative sorting unit which comprises a plurality of openable portions made out of said sliding plane, each being associated with respective collecting means and being opened selectively, as a function of data detected from the reading of the bar-codes at the readout station, so as to discharge the articles into said collecting means.
