Description
1~33414 BACKGROUND OF THE INYENTION
_ The principal objects of this invention are to provide an improved conveyor belt system wherein the conveyor belt is constrained to travel along a predetermined path without deviat-ing therefrom and a conveyor belt system of improved capacity, the invention residing in combining these two desirable features without requiring any substnatial alteration of existing con-veyor equipment. A conveyor supported on troughing rolls to in-crease its capacity for transporting material is shown in United States Patent 3,679,044 and the conveyor belt as illustrated is provided with thickened edges to reinforce these edges. These thickened edges, however, do not function to prevent lateral de-viation of the belt as it travels along its path. Stein United States Patent 3,424,296 shows a rope driven belt conveyor in which the belt instead of being directly supported on idlers is supported by driven ropes. For this purpose, the belt is pro-vided with grooves for receiving the ropes. The primary purpose of the structure shown therein is to distribute the load when traveling over considerable distances. United States Design Patent 24,679 shows a conveyor belt with flanges on the support-ing side at its opposite longitudinal edges. United States Pat-ent No. 4,051,223 shows a belt conveyor wherein the belt has at its opposite longitudinal edges upwardly extending flanges which cooperate with guide rolls su~ported at each side of the belt to maintain the belt centered with respect to its path of travel.
Except for United States Patent 4,061,223, the patents referred to do not combine in a conveyor belt both means for guiding the belt and improving its carrying capacity. However, while this 1~33414 latter patent embodies both these advantages, extensive modification of the conventional conveyor system are required. In contrast, the system as herein illustrated can be used with conventional conveyor structure without modification of the latter.
SUMMARY _ THE INVENTION
The present invention provides a belt conveyor disposed about a pair of terminal rollers and idler rollers at the underside of the upper run and the underside of the lower run, said belt comprising a flexible, uniformly-flat, uniformly-thick laminar material and a single flange at each of the opposite longitudinal edges of the conveyor belt extending upwardly and downwardly from the plane of the belt perpendicular to the plane of the belt, the inner surfaces of said flanges defining transversely-spaced guiding surfaces for engagement with the ends of the terminal and idler rollers, said terminal rollers and idler rollers corresponding in length to the distance between said guiding surfaces, said flanges on the supporting side alternately providing means for guiding the lower run of the conveyor belt and for preventing spill from the upper run of the conveyor belt and said flanges on the opposite side providing for guiding the upper run of the conveyor belt.
The flanges may be attached to the belt or be formed integral therewith. The ends of the terminal rollers and idler rollers may be notched to receive the flanged edges.
The invention will now be described in greater detail by way of example only, with reference to the accompanying drawings, wherein:
FIGURE 1 is a side elevational view of a conveyor assembly showing terminal rollers at the ends and idler rollers intermediate the ends;
-1~334~4 FIGURE 2 is a sectional view taken on the line 2-2 in Figure 1 and as seen in the direction of the arrows;
FIGURE 3 is a section at one end of a conveyor assembly provided with trough idlers;
FIGURE 4 is a transverse section of a belt with flanges projecting upwardly from the support surface;
FIGURE 5 is a transverse section of a belt with flanges of a different configuration at its opposite longitudinal edges projecting upwardly from the support surface;
FIGURE 6 is a cross-section of a belt with flanges such as shown in Figure 5 upwardly and downwardly from both surfaces;
FIGURE 7 is a cross-section of a belt with flanges such as shown in Figure 6 projecting upwardly and downwardly from both surfaces;
FIGURE 8 is a fragmentary portion of a flange strip;
FIGURE 9 is a fragmentary portion of a belt showing attachment of a preformed flange strip to one of its longitudinal edges;
FIGURE 10 is a fragmentary sectional view of a roller notched at its ends to receive a belt provided with flanges such as shown in Figures 4 and 6; and FIGURE 11 is a fragmentary sectional view of a roller notched at its end to receive a belt provided with flanges such as shown in Figures 5, 7 and 9.
Referring to the drawings, Figures 1 and 2, there is shown a conveyor assembly 10 comprising terminal rollers 12 and 14 about which a belt 16 is entrained so that it has an upper ~33414 run 18 and a lower run 20 and idler rolls 22 at the underside of the upper run 18 supporting the same and idler rolls 24 at the underside of the lower run 20 supporting the same. The length of the conveyor belt and spacing of the terminal rollers and the num-ber of idler rollers will depend upon the use for which the con-veyor assembly is designed.
As illustrated in Figures 1 and 2, the terminal rollers and idler rollers support the belt in a transversely horizontal position and in accordance with this invention, there are provided at the opposite longitudinal edges of the belt upstanding flanges which function on the one hand to increase the capacity of the belt for holding m-aterial being conveyed on the portion of the belt comprising the upper run and on the other hand as means for guiding the portion of the belt comprising the lower run by engage-ment with the opposite ends of the terminal rollers and the idler rollers. The flanges 26-26 may comprise portions 26a and 26b pro-jecting from the opposite faces of the belt as shown in Figure 2.
The flanges 26a when traveling along the upper run constitute means for increasing the capacity of the belt for carrying mater-ial and when traveling along the lower run, guide means engagedwith the ends of the rolls. The flanges 26b comprise guides when traveling along the upper run and about the terminal rollers.
The flanges 26-26, Figures 1, 2 and 6 are shown as being formed integral with the longitudinal edges of the belt and ex-tending from both surfaces. However, the belt may be provided with flanges 26a extending from only one surface as shown in Figure 4, preferably the surface which will provide for increas-ing the capacity of the belt as a conveyor while traveling ~133414 along the upper run as well as providing guiding means.
In lieu of integrally formed flanges, strips of welting 26c of substantially truncated cross-section may be fastened to one or both sides of the belt as shown in Figures 5 and 7. Optionally, a channeled welting strip 26d may be formed, for example, as an extrusion with a channel 28 for receiving the edge of the belt and for attachment thereto, for example, by means of adhesive as shown in Figure 9.
While as illustrated above, the terminal rollers and idler rolls are of uniform cross-section from end to end, it may be desirable to provide notches or recess 30 at the ends of the rollers to receive the flanges as shown, for example, in Figures 10 and ll. The invention is also applicable to a conveyor system wherein the belt is supported centrally on terminal rolls and idler rolls and at its opposite sides by trough idlers inclined to the horizontal as shown in Figure 3. As illustrated therein, the upper run 18a of the belt rests on horizontally-disposed rollers 22a and the opposite sides of the belt rest on inclined rollers 22b. The lower run 20a rests on long horizontal rollers 24a. As in the previously described structure, the belt is pro-vided with end flanges 26-26 which project from the opposite faces on the carrying side to increase the capacity of the belt and on the return side to provide guidance for the belt.
The belt is comprised of any suitable laminate and the flanges may be affixed to the longitudinal edges by hot or cold cure or by mechanical fasteners.
The flanges such as disclosed in Figures 4 and 5 de-sirably are 1/2 inch in thickness and l/2 to l-l/2 inches in height. The flanges shown in Figures 5 and 7 are 1-1/2 to 1-1/4 inches wide at the base and 1/32 to 3/4 of an inch in height.
To be effective, the minimum roller diameter for the terminal rollers for either type must be approximately 3 inches.
The advantage of this construction is that it is suitable for use on existing conveyor systems where a clearance space between the bearings, shafts and frames is available and so without redesign or modification of existing equipment.
It should be understood that the present disclosure is for the purpose of iilustration only and includes all modi-fications or improvements which fall within the scope of the appended claims.
