Abstract

PURPOSE:To obtain a conveyor, which withstands its supporting load, which is characterized in both surfaces not stuck to an adhesive, and whose durability, and economical feature are improved, with its simple structure, by making each of load receiving platforms to have one engaging member with a supporting bar at its front and rear ends and making each platform to be positioned by cooperative supporting bars for both members. CONSTITUTION:A load supporting surface 8 is constituted by continuous load receiving platforms 9, which are inserted and engaged with the others in turn. Each platform 9 is fitted around a supporting bar 6 by a front-end-engaging part 11, while a rear-end-engaging part 12 is fitted around the front-end- supporting part of the preceding platform. In this way, an assembly is made up of a series of hard, steel members overlapping with each other. In addition, owing to a mutual, shaft-supporting system made up of many constitutional components, each member is able to move around an end-supporting roller 1 very easily. Thus, a conveyor obtained like this may possess a hard surface, which is supported between two supporting rolls, and is extremely suitable for conveying unvulcanized rubber material.

TECHNICAL FIELD This invention relates to conveyors. More particularly, it relates to a conveyor for conveying materials such as unvulcanized rubber compounds.

0002

BACKGROUND OF THE INVENTION Conveyors used to convey materials such as flexible and sticky unvulcanized rubber compounds have surface properties that are sufficient to withstand the supporting load and that the sticky materials do not stick easily. It is required to have a combination of surface properties. Such conveyor surfaces are also required to be durable, low cost, and of simple construction. This achieves easy maintenance and good adaptability, and allows the conveyor to be made with small dimensions, so that it has a small center wheel.
els) can be used. In this way, the conveyor is easily adapted to large mixing machines and compound processing machines.

0003

[Problems to be Solved by the Invention] However, no conveyor has hitherto been provided that has both of the above-mentioned surface characteristics, is excellent in durability and economical efficiency, and is simple in structure. The object of the invention is to provide such a conveyor.

SUMMARY OF THE INVENTION According to one aspect of the invention, a conveyor includes a pair of spaced side drive members and a drive member that moves the drive members at the same speed along the length of the conveyor. comprising a drive means for driving, a series of laterally extending parallel support bars equally spaced between said drive members, and load-receiving platforms arranged overlapping each other, said platforms each comprising: Each platform has an engagement member at the leading end and one at the rear end for engaging the support bar, and each platform is positioned with respect to both cooperating support bars. Preferably, an engaging member at a leading end of the platform directly engages with the support bar, and an engaging member at a rear end indirectly engages with the supporting bar. Preferably, said indirect engagement is achieved by an engagement member at the rear end of said platform engaging an engagement member at the leading end of an adjacent next platform. In such an arrangement, the support bar is a rod having a circular cross-section, and the engagement member has a circular engagement surface cooperating with the support bar to connect the load receiving platform to the conveyor assembly. Hold it in three dimensions.

[0005] Preferably, the platform is made of sheet steel material. This is because they are inexpensive, have excellent durability, and are extremely suitable for transporting rubber materials.

BRIEF DESCRIPTION OF THE DRAWINGS Further features of the invention will become apparent from the following description, given by way of example only and in conjunction with the accompanying drawings, in which: FIG.

FIG. 1 is a perspective view of one end of the conveyor of the present invention;
FIG. 2 is a partial illustration illustrating details of engagement of adjacent support platforms, and FIG. 3 is a side view of a single load-bearing platform.

The conveyor of the present invention comprises two drive chain sprockets or center wheels and both sides of the conveyor (only one side 2 of which is shown in FIG. 1).
It consists of a driving member 4 that is continuously connected. 2
One of the three drive sprockets is designated by reference numeral 1 in the figures. The drive member 4 consists of a long chain that engages the central wheel at both ends of the conveyor. In this way, the drive chains 4 on both sides of the conveyor are driven synchronously. At a number of spaced locations along the length of the lateral drive chain 4, connection points 5 are provided in laterally extending rigid steel bars 6. The bars 6 extend across the width of the conveyor and provide a lattice of spaced support bars. Each support bar has a drive support shaft 7 projecting from both ends thereof. Although any of the systems known in the art for equipping the conveyor ends with rigid long supports can be used, in the present invention these support shafts 7 are typically fitted with support rollers to reduce friction. engages the side supports of the conveyor. Thus, in the conveyor of the present invention, a laterally extending support bar 6 is carried along the path of the conveyor, rotates around the end rollers and returns along the bottom of the conveyor.

The load receiving surface 8 is provided by a continuous pressure receiving platform 9 which is inserted and engaged. Each platform 9 consists of a substantially flat support surface 8a of length L, L being the length of the conveyor, slightly greater than the distance between two adjacent lateral support bars 6. The tip 10 of the platform 9 is bent downward,
As shown in the figure, a tip engaging portion 11 having an inner radius R1 is formed. The rear end engaging portion 12 of the platform 9 is formed by a member having an engaging function and having a width R2 in substantially the same manner as the front end engaging portion 11.

As shown in FIG. 2, each platform 9 is fitted around the support bar 6 by its distal engagement portion 11, and further has a rearward engagement portion 12 fitted around the support bar 6 by its distal engagement portion 11.
(evious) is fitted around the tip support of the platform. Thus, as shown in FIG. 2, the assembly consists of a series of overlapping rigid steel members. Due to the pivoted interconnection of a large number of components, these parts can be moved around the end support roller 1 very easily. The resulting conveyor has a hard surface supported between two support rails and has been found to be highly suitable for conveying unvulcanized rubber materials.

Effects of the Invention The conveyor of the present invention consists of a plurality of interconnected platforms made of hard steel.
It has a hard surface that can withstand the supporting load and is extremely suitable for conveying flexible, sticky, unvulcanized rubber materials.
