TECHNICAL FIELD
Present disclosure, in general, relates to a field of manufacturing. Particularly, but not exclusively, the disclosure relates to manufacturing of rollers. Further, embodiments of the present disclosure relate to manufacturing of a composite idler roller for conveyer applications.

BACKGROUND OF THE DISCLOSURE
Conveyers are employed to automatically channelize and/or transport raw materials, assembly-line products, finished products, and other goods, in a fixed path between two predetermined locations. Further, the conveyers, in general, employ rollers for assisting in handling and discharging load of the products and/or goods between said locations. The rollers may be configured to roll at a predefined speed in order to deliver the products and/or goods.

Conventional conveyers employ rollers that made from metal or metallic alloys and, may be automated to channelize and/or transport products or goods to defined locations. The rollers of the conventional conveyers are generally heavy due to their manufacturing material and for use of such manufacturing materials, the conventional rollers may be limited in their usage in different environmental surroundings. That is, performance of the conventional rollers may be affected due to environmental factors including, but not limited to, corrosiveness, humidity, and the like.

Additionally, the conventional rollers that may be manufactured from metals or similar metallic materials, may include dimensional variations across the length of the rollers due to process such as, but not limited to, welding, grinding, and the like, involved during manufacturing of such rollers. Also, supplementary components of the rollers including, but not limited to, bearing assembly, sealing assembly, and the like, may required to be connected to the rollers by connecting means such as, welding or fastening. Due to such connecting means, the assembly, servicing and maintenance time may increase due to complexity in disassembling and re-assembling the supplementary components of the rollers. In addition, the heavy weight of the rollers may also hinder during servicing and maintenance of the rollers.

The present disclosure is directed to overcome one or more limitations stated above.

While the embodiments of the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

It is to be noted that a person skilled in the art would be motivated from the present disclosure and modify various shapes, profiles, orientation and configurations of plurality of grooves in a housing for a composite roller. However, such modification should be construed within the scope and spirit of the instant disclosure. Accordingly, the drawings show only those specific details that are pertinent to understand the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having benefit of the description herein.

Further the assembly includes a housing, configured to radially support the composite elongated member on each end. The housing includes a plurality of grooves, defined on an outer periphery of the housing. Here, at least one groove of the plurality of grooves is configured to receive an adhesive and an other groove of the plurality of grooves, away from the one groove, is configured to dispense a portion of the adhesive. The housing further includes a clearance region, defined between the plurality of grooves. The clearance region is structured to connect each of the plurality of the grooves such that, the adhesive is channelized between at least two grooves of the plurality of grooves for joining the elongated member with the housing. With such configuration, problems associated with assembling lead time and requirement of a skilled operator for joining components of the assembly is avoided. Additionally, dimensional variations between the housing and surfaces of the elongated member may be adjusted by regulating quantity of adhesive being supplied, whereby reducing manufacturing defect losses. Also, the assembly of the present disclosure eliminates necessity of employing heavy roller materials, whereby rendering the assembly of the present disclosure simple, light in weight and economical.
In an embodiment, the term “elongated member” referred hereafter, may be considered as an element or a component being dimensioned with its length greater than width and height. The elongated member may be hollow and be defined with various cross sectional profiles including, but not limited to, circular, square, rectangular, and any other profile capable of rolling about an axial axis, with or without significant aid from an external power source. The external power source may be at least one of an engine, a motor, a pump, a compressor, and any other prime mover capable of transmitting torque to the elongated member for use in a conveyor system.

Also, the term “substantially” referred hereafter, may be interpreted as dimension or composition have equal or almost equal values to that of a pre-manufacture and dimensioned corresponding component. For example, the elongate member and the housing may have equal or almost equal dimensions for a snug fit therebetween. Also, the bearing assembly and internal periphery of the housing may have almost equal dimensions to have an interference or transitional fit therebetween.

In the following description of the embodiments of the disclosure, reference is made to the accompanying figures that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.

Figure 1 is an exemplary embodiment of the present disclosure which illustrates a sectional view of a composite roller assembly (100). The composite roller assembly (100) [hereinafter interchangeably referred to as “the assembly” or “the composite roller”] may include an elongated member (1) , that may be produced by various manufacturing processes including, but not limited to, seam welding, filament winding, lamination winding, lay up, 3D printing, and any other manufacturing process capable for producing a hollow product with length being greater than width [or radius in case of curved profiles]. In the exemplary embodiment, the elongated member (1) may be pultruded through cylindrically profiled structures having optimum tolerances to produce cylindrical and/or elliptical profiled elongated member (1), having substantially uniform thickness. The uniform thickness may minimize warpage along surfaces of the elongated member (1). The elongated member (1) which is pultruded, may include seamless surface to form an outer region of the composite roller (100). The elongated member (1) may be formed about a central axis to define a predetermined diameter for the composite roller (100). In an embodiment, the elongated member (1) may be dimensioned with a defined thickness such that, the elongated member (1) may be employed in a conveyor system [not shown in figures] for transporting necessary articles from one position to another. The defined thickness of the elongated member (1) may be determined based on parameters including, but not limited to, stiffness required for the elongated member (1), wear resistance, self-weight, operating speed, and any other parameter affecting performance of the conveyor system.

Further, the elongated member (1) being formed may be dimensioned such that, a housing (2) may be snugly accommodated [by way of press fitting, snap fitting, and the like with interference or transitional fit therebetween] at either side of the elongated member (1). That is, the elongated member (1) may be formed/produced to a shape and dimension that may be substantially equal to the dimension of the housing (2), which may be pre-formed for a defined application. Additionally, minimal tolerance may be defined between the housing (2) and an inner periphery [or also referred to inner surface] of the elongated member (1) in order to form at least one of a transition fit or an interference fit. Due to such tolerance and fitting between the housing (2) and the elongated member (1), wobbling and/or swaying motions during operation of the composite roller (100) may be mitigated. In an embodiment, the housing (2) may be made from a rigid material such as, but not limited to, metal like mild steel, stainless steel, Aluminium, glass reinforced polyester, fiber reinforced polymer, and the like, to support the elongated member (1) for rolling operations. The elongated member (1) may be made from materials including, bit limited to, glass, carbon in filament or staple form reinforce polyester, thermoplastic, thermoset composite, vinyl ester, epoxy, phenolic, polyurethane, polypropylene and polyethylene.

Referring now to Figure 2a, which illustrates a magnified view of the composite roller (100) of Figure 1. The housing (2) may be defined with a fixing arrangement, which may include a plurality of grooves (3) being defined at predetermined locations on the housing (2). In an embodiment, the plurality of grooves (3) may be defined about an outer periphery of the housing (2) such that, the plurality of grooves (3) may be adapted to fluidly connect the housing (2) and the inner surface of the elongated member (1) . The plurality of grooves (3) may be configured to receive an adhesive, for securing the elongated member along the periphery of the housing (2). The dimension of each groove of the plurality of grooves (3) may either be varied or maintained uniform about the outer periphery of the housing (2), based on extent of bonding required between the housing (2) and the elongated member (1) . In an embodiment, the plurality of grooves (3) may be defined by processes including, but not limited to, milling, laser cutting, forming, chemical etching, and any other material removing process.

The housing (2) may also include a clearance region (4), as best seen in Figures 2a, 2b and 4, which may be defined along the outer periphery of the housing (2). The clearance region (4) as shown in Figures 2a and 2b, may formed to connect at least two of the plurality of the grooves (3) such that, the at least two grooves (3) of the plurality of grooves (3) form an inlet runner (5) and an outlet runner (6) for flow of an adhesive between the housing (2) and the elongated member (1) . Further, the inlet runner (5) and the outlet runner (6) may be defined such that, the inlet runner (5) and the outlet runner (6) may fluidly connect the inner surface of the elongated member (1) with that of the outer surface. Due to this, adhesive may be supplied and/or injected between the housing (2) and the elongated member (1), rather than merely applying at different portions thereof. The adhesive may be supplied and/or injected through inlet runner (5) and may be supplied or injected or applied by hand before insertion of the housing (2) in the elongated member (1) until a portion of such adhesive may overrun from the outlet runner (6) in order to ensure adequate quantity of adhesive being supplied thereof. In an embodiment, the plurality of grooves (3) are defined with a slot, extending from the outer periphery of the housing (2) to a predefined depth, and wherein the slot is configured to contain the supplied adhesive for joining the composite elongated member (1) with the housing (2). The slot may resemble at least one a counterbore and a countersink, in order to selectively retain a proportion of adhesive that may engage and wet a portion of a surface of the elongated member (1) relative to the housing (2). Meanwhile, during overrun of the adhesive from the outer runner, the clearance region (4) between the inlet runner (5) and the outlet runner (6) may be configured to accommodate the adhesive so that, area of bonding between the outer periphery of the housing (2) and the inner surface of the elongated member (1) may be increased. This way, the elongated member (1) and the housing (2) may be bonded by the adhesive, along with provision for adequate dimensional tolerance limit in forming the composite roller (100).

In an embodiment, the composite roller (100) may also include a bearing assembly (7), that may be fitted at either ends of the housing (2). The bearing assembly (7) may be fitted along an inner periphery of the housing (2), as seen in Figure 3. The bearing assembly (7) may be rigidly fitted to the housing (2) by means including, but not limited to, press-fitting or by providing circlips on both ends of the bearing assembly, and the suitable positioning means. Further, a shaft (8) of predefined diameter may be introduced into the housing (2), through the bearing assembly (7), along the central axis of the composite roller (100), for enabling rolling operation. The bearing assembly (7) may be configured to apply normal pressure on the shaft (8) so that, the shaft (8) may not deviate from the central axis of the composite roller (100). Additionally, the composite roller (100) may include a plurality of circlips (9) provided at either ends of the bearing assembly (7), to normally fix the bearing assembly (7) relative to the shaft (8). Due to provision of the plurality of circlips (9), the bearing assembly (7) may be maintained normal to the shaft (8) thereby, reducing wear due to eccentric alignment of bearings in the bearing assembly (7) with the shaft (8), during rolling operation.

In an embodiment, the composite roller (100) may further include a plurality of sealing members (10), as can be seen in Figure 2b, which may be accommodated in the housing (2). The plurality of sealing members (10) may be positioned on either side of the bearing assembly (7) at each end of the housing (2). The plurality of sealing members (10) may be configured to provide ingress protection to the bearing assembly (7).

Referring now to Figures 3a and 3b, which illustrate a different configuration of the composite roller (100). The housing (2) of the composite roller (100) in Figures 3a and 3b may be defined with a flange (11). The flange (11) may include an extended portion, which may surrounding the elongated member (1) at either sides, where the extended portion of the flange (11) may circumferentially be off-set by a predefined distance from the ends of the elongated member (1) . Further, the flange (11) may be off set from the either ends of the elongated member (1) in order to avoid frictional contact. In an embodiment, the flange (11) may be made from an electrical conducting material such as, but not limited to, copper, iron, and the like, where the flange (11) may be configured to channelize static electricity that may be produced during rolling operation of the composite roller (100).

In an embodiment, the plurality of grooves (3) may also be profiled to include the clearance region (4) without fluidly connecting the inner surface and the outer surface of the elongated member (1) , as shown in Figure 4. The plurality of grooves (3) may resemble a threaded profile (12) on the outer periphery of the housing (2). Further, the depth of the threaded profile (12) may be configured to accommodate the adhesive and, in similar sense to the inner and outer runner, may increase the area of bonding between the housing (2) and the elongated member (1) . It may be noted that, the plurality of grooves (3) may be defined with various profiles and configurations on the housing (2), to impart increased area of bonding between the housing (2) and the elongated member (1) thereof, without deviating from the working principles. In an embodiment, the threaded profile (12) may be design with angular tapered regions in one direction in order to reduce shear failure in the thread. The angular tapered regions of the threaded profile (12) in the housing (2) may consist of an angular side and a normal side, where the angular side and the normal side may include at an angle ranging from about 5° to about 45°. The angular tapered regions may resemble a saw-tooth profile that may be horizontally eccentric from an inner surface of the housing (2) to define a passage for flow of the adhesive. Further, by employing threaded profile (12) in the housing (2), strength of the composite roller assembly (100) may be increased. These configurations may be used for higher load bearing application or dead shaft idler roller configuration.

In an embodiment, the elongated member (1) produced by such pultrusion process may be include properties such as, but not limited to, high load bearing capacity, well-defined dimensional tolerance, corrosion resistance, and the like. Additionally, as composite materials or matrix is employed, weight of the composite roller (100) may substantially be less when compared to the rollers made from metals.

In an embodiment, due to adhesive bonding between the components of the composite roller (100), time period for assembling and disassembling of such components may be reduced. Also, serviceability, maintenance and/or replacement of the components may be readily performed without having to disassemble other components.

In an embodiment, the adhesive supplied between the housing (2) and the elongated member (1) may also be employed for adjusting dimensional tolerance and limit between either ends of the composite roller (100).

It should be construed that the various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. That is, application of the composite roller assembly may not be limited to a conveyer system, rather, such assemblies may be employed in other fields of manufacturing.
