Abstract
Abstract Method and apparatus for checking discrete articles for the presence of applied labels. The articles are advanced past a control station where their presence is detected and a scanning device activated in response to such detection. The scanning device mechanically scans the detected article for the presence of a label and generates, in the absence thereof, an indication of such absence.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A method of checking discrete articles for the present of applied labels, comprising the steps of advancing a plurality of discrete articles in a predetermined path and past a control station; detecting the arrival of each article at said control station, and generating a signal in response to such detection; contacting the respective detected article at said control station with a scanning instrumentality in response to generation of said signal, and effecting displacement of said instrumentality normal to said path and relative to said article in the presence of a label on a predetermined portion of said article; and generating, in the absence of such displacement and consequently of the label from said portion, an impulse indicative of such absence and of the rejection of the article.
Claim 2
Independent Claim
127 words
A method of checking discrete articles for the present of applied labels, comprising the steps of advancing a plurality of discrete articles in a predetermined path and past a control station; detecting the arrival of each article at said control station, and generating a signal in response to such detection; contacting the respective detected article at said control station with a scanning instrumentality in response to generation of said signal, and effecting displacement of said instrumentality normal to said path and relative to said article in the presence of a label on a predetermined portion of said article; and generating, in the absence of such displacement and consequently of the label from said portion, an impulse indicative of such absence and of the rejection of the article.
Claim 3
Dependent Claim
25 words
A method as defined in claim 1, and further comprising the step of segregating the thus rejected article in response to generation of said impulse.
Claim 4
Dependent Claim
149 words
Apparatus for checking discrete articles for the presence of applied labels, comprising in combination, advancing means for advancing a plurality of discrete articles in a predetermined path past a control station; detecting means for detecting the arrival of each article at said control station, and for generating a signal in response to such detection; scanning means associated with said detecting means and including an elongated feeler member extending across said path for engagement with the respective articles and mouNted for displacement normal to said path by a predetermined extent in response to encountering of a label on a predetermined portion of the article; and impulse-producing means associated with said scanning means and operative for generating, in the absence of said displacement of said feeler member and consequently in the absence of a label from said portion, an impulse indicative of such absence and of the rejection of the article.
Claim 5
Dependent Claim
149 words
Apparatus for checking discrete articles for the presence of applied labels, comprising in combination, advancing means for advancing a plurality of discrete articles in a predetermined path past a control station; detecting means for detecting the arrival of each article at said control station, and for generating a signal in response to such detection; scanning means associated with said detecting means and including an elongated feeler member extending across said path for engagement with the respective articles and mouNted for displacement normal to said path by a predetermined extent in response to encountering of a label on a predetermined portion of the article; and impulse-producing means associated with said scanning means and operative for generating, in the absence of said displacement of said feeler member and consequently in the absence of a label from said portion, an impulse indicative of such absence and of the rejection of the article.
Claim 6
Dependent Claim
31 words
Apparatus as defined in claim 3, said detecting means comprising a photoelectric detecting device including a light-source at one side and a detector located at the other side of said path.
Claim 7
Dependent Claim
18 words
Apparatus as defined in claim 3, wherein said feeler member extends across said path at an acute angle.
Claim 8
Dependent Claim
19 words
Apparatus as defined in claim 3, wherein said feeler member consists at least in part of elastically yieldable material.
Claim 9
Dependent Claim
42 words
Apparatus as defined in claim 3, said feeler member including a front portion arranged to contact said articles, a rear portion remote from said front portion, and an intermediate portion; and further comprising support means connected to and supporting said rear portion.
Claim 10
Dependent Claim
38 words
Apparatus as defined in claim 7, said scanning means further comprising an abutment portion located below said intermediate portion laterally of said path, said intermediate portion normally resting on said abutment portion and being deflectable upwardly away therefrom.
Claim 11
Dependent Claim
24 words
Apparatus as defined in claim 8, wherein said abutment portion is a portion of said support means and constitutes with the same a unit.
Claim 12
Dependent Claim
42 words
Apparatus as defined in claim 8, wherein said feeler member constitutes one contact of an electrical switch; and further comprising a contact member provided on said abutment portion for engagement by said feeler member and constituting the other contact of the switch.
Claim 13
Dependent Claim
94 words
Apparatus as defined in claim 7, said front portion of said feeler member having a contact tip arranged to engage said portion of said article; and said scanning means further comprising actuating means associated with said support means and operative for effecting movement of the same, and thereby of said feeler member, in direction normal to said path in response to generation of a signal by said detecting means so that said contact tip of said feeler member slides over said portion of said article scanning the same for the presence of a label.
Claim 14
Dependent Claim
12 words
Apparatus as defined in claim 11, said actuating means being electromagnetic means.
