Abstract

Abstract Apparatus for turning flat articles supported on a substantially flat surface, including a device for receiving a serial stream of the articles, each of which travels along a first linear path, and a device for rotating each article through a preselected angle and for then steering the articles in a preselected direction. The rotating device includes a first and second pair of fixed, positioned rollers whose axes are located at substantially a right angle to each other. The apparatus further includes a guiding device and a conveyor which causes the articles to move along a path which is parallel to the preselected path of travel. The apparatus is utilized in executing a method of receiving, rotating and conveying the articles along the preselected direction.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 159 words
Apparatus for turning flat articles, comprising: (a) means for receiving a serial stream of said articles each traveling along a first linear path; (b) means for rotating each of said articles of said stream through a preselected angle and for steering each of said articles in a preselected direction of travel wherein said rotating and steering means includes (i) a first and second pair of fixed, positioned rollers the axes of which are located at substantially a right angle to one another, and (ii) means which in a first mode urges said articles to continue along said first linear path and in a second mode urges said articles to progress along a second linear path at a substantially right angle to said first linear path; (c) means for guiding each of said articles to said rotating and steering means; and (d) means for conveying each of said rotated articles along a path parallel to said preselected direction of travel.
Claim 2
Dependent Claim 159 words
Apparatus for turning flat articles, comprising: (a) means for receiving a serial stream of said articles each traveling along a first linear path; (b) means for rotating each of said articles of said stream through a preselected angle and for steering each of said articles in a preselected direction of travel wherein said rotating and steering means includes (i) a first and second pair of fixed, positioned rollers the axes of which are located at substantially a right angle to one another, and (ii) means which in a first mode urges said articles to continue along said first linear path and in a second mode urges said articles to progress along a second linear path at a substantially right angle to said first linear path; (c) means for guiding each of said articles to said rotating and steering means; and (d) means for conveying each of said rotated articles along a path parallel to said preselected direction of travel.
Claim 3
Dependent Claim 25 words
Apparatus as set forth in claim 1 wherein said receiving means includes a structural support including a substantially flat surface for serially receiving said articles.
Claim 4
Dependent Claim 47 words
Apparatus as set forth in claim 2 wherein said rotating and steering means further comprises means for rotatably supporting said first and second pair of rollers so that their respective conveying nips are slightly elevated above said flat surface in order to engage said articles guided thereto.
Claim 5
Dependent Claim 21 words
Apparatus as set forth in claim 1 wherein each of said roller pairs includes a driver roller and an idler roller.
Claim 6
Dependent Claim 15 words
Apparatus as set forth in claim 4 further comprising means for driving said drive rollers.
Claim 7
Dependent Claim 19 words
Apparatus as set forth in claim 3 wherein said roller pairs are capable of conveying articles of varying thickness.
Claim 8
Dependent Claim 30 words
Apparatus as set forth in claim 6 wherein said ability to convey articles of varying thickness is achieved by resiliently biasing one roller of each of said pair of rollers.
Claim 9
Dependent Claim 32 words
Apparatus as set forth in claim 1 wherein said guiding means comprises a fixed position fence for guiding each of said articles to the conveying nip of said first pair of rollers.
Claim 10
Dependent Claim 31 words
Apparatus as set forth in claim 8 wherein said fence includes a pivot point in line with the centerline of said first pair of rollers about which said articles are rotated.
Claim 11
Dependent Claim 26 words
Apparatus as set forth in claim 9 further comprising means for biasing received articles to be grabbed by the nip of said first pair of rollers.
Claim 12
Dependent Claim 40 words
Apparatus as set forth in claim 9 wherein said fixed fence includes a member which said articles initially engage while traversing said first path to cause each article to be biased towards said nip of said first pair of rollers.
Claim 13
Dependent Claim 43 words
Apparatus as set forth in claim 1 wherein said urging means comprises: (a) a solenoid; and (b) a pin, driven by said solenoid, which in said first mode is below said flat surface and in said second mode is above said flat surface.
Claim 14
Dependent Claim 29 words
Apparatus as set forth in claim 1 wherein said preselected angle of rotation of each said articles is 90° in said first mode and 180° in said second mode.
Claim 15
Independent Claim 167 words
A method for turning flat articles, comprising: (a) receiving a serial stream of said articles each traveling along a first linear path; (b) rotating each of said received articles through a preselected angle and steering each of said articles in a preselected direction of travel wherein said rotating and steering is performed by a first and second pair of fixed, positioned rollers the axes of which are located substantially at right angles to one another, each of said roller pairs including a drive roller and an idler roller, said rotating and steering further including, in a first mode, urging said articles to continue along said first linear path and, in a second mode, urging said articles to take a second linear path at a right angle to said first linear path; (c) guiding each of said received articles to at least said first pair of rollers; (d) driving said drive rollers; and (e) conveying each article rotated down a path parallel with said preselected direction of travel.
Claim 16
Independent Claim 167 words
A method for turning flat articles, comprising: (a) receiving a serial stream of said articles each traveling along a first linear path; (b) rotating each of said received articles through a preselected angle and steering each of said articles in a preselected direction of travel wherein said rotating and steering is performed by a first and second pair of fixed, positioned rollers the axes of which are located substantially at right angles to one another, each of said roller pairs including a drive roller and an idler roller, said rotating and steering further including, in a first mode, urging said articles to continue along said first linear path and, in a second mode, urging said articles to take a second linear path at a right angle to said first linear path; (c) guiding each of said received articles to at least said first pair of rollers; (d) driving said drive rollers; and (e) conveying each article rotated down a path parallel with said preselected direction of travel.
Claim 17
Dependent Claim 30 words
A method as set forth in claim 14 wherein said step of receiving further includes the step of supporting, on a substantially flat surface, each of said serially received articles.
Claim 18
Dependent Claim 23 words
A method as set forth in claim 14 further comprising the step of biasing said idler rollers to accommodate articles of varying thickness.
Claim 19
Dependent Claim 38 words
A method as set forth in claim 14 wherein the step of rotating and steering further comprises the step of pivoting each article about a pivot point in line with the centerline of said first pair of rollers.
Claim 20
Dependent Claim 30 words
A method as set forth in claim 14 further comprising the step of rotating each article 90° in said first mode and rotating each article 180° in said second mode.
