FLEXIBLE FEED TRACK Filed Jan. 26, 1959 v www .IN VEN TOR.
/7 T Taf/7,575,
United States Patent i 3,002,600 FLEXIBLE FEED TRACK Milford A. Campbell, 17225 MacArthur, Detroit, Mich. Filed Jan. 26, 1959, Ser. No. 789,002 4 Claims. (Cl. 193-25) This invention relates generally to conveyors and more particularly to liexible track.
'The object of this invention, therefore, is to provide a flexible track for transporting articles by gravity along and irregular path; to provide a track which is adapted to a large number of uses because it can be formed of substantially any desired cross-sectional shape to accommodate articles to be transported which are of a certain shape; and to provide a track which provides continued access to the parts in the track.
-A further object of this invention is to provide a flexible track which is simple in construction; economical to manufacture, and which is easily bent and twisted to conform to a desired path of travel for parts being transported.
`Further objects, features and advantages of this invention will become apparent from a consideration of the following description and the appended claims, when taken in connection with the accompanying drawing in which:
FIGURE 1V is afragmentary perspective view showing three tracks of this invention mounted on a frame for receiving parts to be transported from a machine or conveyor;
FIGURE 2 is a transverse sectional view looking along the line 2--2 in FIG. 1;
FIG. 3 is an enlarged fragmentary sectional View looking along the line 3 3y in F'IG. 2; and
FIG. 4 is a sectionalview'looking along the line 4--4- inFIG.2.'
With reference to the drawing, three tracks of this invention, indicated generally at 10, a and 10b are illustratedin FIG. l mounted on a frame 12 for receiving parts 14 from a conveyor 16.A Since the tracks 10, 10a and 10b are substantially identical, only the track 10 is described in detail hereinafter, with like numerals indicating like parts on the tracks.
The track 10 consists of a plurality of segments 20, each of which is formed or Wire, preferably a high quality, high carbon drawn spring wire, and each of which is of a shape corresponding substantially to the cross-sectional shape of the track 10 required for transporting the parts 14. As used herein, the term wire describes an elongated strip of metal or similar material which is of a small size in cross section as compared to its length. It can be of any suitable cross section such as the conventional round shape, a iiatter ribbon shape and the like. In this case, since each part 14 is of a substantially rectangular shape in elevation, as shown in FIG. 2, each segment 20 is of the substantially rectangular shape illustrated. However, the segment 20 is an incomplete rectangle because its ends 22 are separated by a gap or space 24. Each segment 20 is of a substantially loop shape for defining a track having a long side 26, short sides 28, and a partial side 30.
A plurality of side by side segments 20 are formed by coiling a wire strip around a mandrel of a shape corresponding to the desired segment shape and heating the strip so that each coil retains the shape illustrated in FIG. 2. The track 10 is formed by packing the coils tightly against each other in a side-by-side relation, as illustrated in FIGS. 3 and 4, and a longitudinally extending slot 36 is then formed in the coil to thereby form the segments 20 having the aligned gaps 24. The segments 20 are maintained in this position by maintaining them on a Patented Oct. 3, 1961 lAC mandrel and a coating 34 is then applied to the segments 20 tomaintain them in the side-by-side relation. Since the wire from which the segments 20 are formed was in a helical or coil form, the ends 22 of each segment are not in the same plane. However, because the coils are packed tightly against each other, the ends 22 in each segment are only slightly offset, so that adjacent segments can be described as being in substantially parallel planes.
The coating 34 may be of any ilexible material or materialswhich will provide for an adhesion of the coating to the segments 20. One example of a suitable coating is neoprene which is applied so that it completely covers the outer surface of the side-by-side segments 20 but does not cover inner surface of the segments or the slot or opening 3'6 formed by the gaps 24 in the segments 20. It is desirable to confine the flexible coating 34 to the outer sides of the segments 20 as shown in FIG. 3
so that the uncoated inner sides of the segments provide y sole support for the articles in the way deiined by the track. The metallic inner sides of the segments 20 provide a hard, Wear-resistant sliding surface having uniform and predictable sliding characteristics for the articles in the track.
A track which is formed as described above can readily be cut to any desired length since it is necessary only to cut the coating 34 between a pair of adjacent segments 20. One of the advantages of theY track member 10is:
that it can'be bent or twisted, by virtue of the ilexible nature of the coating 34 and the fact that the track is v formed of individual segments 20, so that it will extend along an .irregular path required for transporting the `parts 14 to a desired location. As shown in FIG'. 1, the
14 discharged from the track. The top half of the track 10b is`removed adjacent its discharge end to facilitate observation of the articles 14.
:The tracks r10, 10a and 10b aremounted on the framev f 12 by means of a three part clamp unit 41 which is secured to the frame 12 and clamped to the upper ends of the tracks 10, 10a and 10b so as to locate the tracks in side-by-side positions for receiving articles 14 from the conveyor 16. One or more clamps 40 are secured to each of the tracks 10, 10a and 10b at a position intermediate the ends thereof for maintaining the track in a desired position. Each clamp 40 includes a sleeve 42 in which one end of a shaft 44 is rotatably supported.
The shaft 44 is connected to the frame 12 in any manner which is eiiective to hold the clamp 40 in a position necessary to hold the track 10 in a desired position. In many cases additional shafts 46 and brackets 47 are utilized. Each bracket 47 consists of two integral sleeves 48 and 50 which are arranged at right angles relative to each other for accommodating a pair of shafts 46 which are at right angles.
Although the invention has been described with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited since changes can be made therein which are Within the full intended scope of this invention as deiined by the appended claims.
