Description

Title: Modular conveyor belt
The invention relates to a modular conveyor belt. Such belts are relatively popular for conveying products as their modular structure allows them to be manufactured cost effectively in different lengths and widths.
Generally, such modular belts usually include two types of modules, 5 edge modules located along the longitudinal edges of the belt, and intermediate modules located there between.
Depending on the use of the belt, the modules may be designed with a specific base layout that is e.g. optimized for travel around curves in a conveying plane. Further, modules with the same base layout may be 10 embodied with different types of top surfaces, e.g. a top surface adapted for maximum open area to allow passage of fluid or a top surface with maximum closed area to allow for maximum product support.
As the modules are usually manufactured by injection moulding of plastics material, the tooling costs for each different type of module are 15 relatively high. For a particular basic layout in which the modules comprise a central portion with transversely spaced forwardly extending link ends, and transversely spaced rearwardly extending link ends, and transversely spaced rearwardly extending link ends with the forwardly and rearwardly extending link ends being transversely staggered relatively to each other, and in which 20 the central portion of the modules at the interspace between two last adjacent link ends of the end section have been provided with a product support shelf, it is a problem to intermix these modules in a belt with modules in which the last link ends of the end section are free of a product support shelf. In particular, it is not possible to successfully use edge modules of such a belt designed with a 25 product support shelf with intermediate modules that are free of product support shelves as the top surface of the modules does not match up. In addition, such intermediate modules of that basic design without product 2004116 2 support shelf could easily be mounted mistakenly up side down in the belt. In order to solve this problem, the invention provides for a modular conveyor belt, comprising a number of rows of modules succeeding each other in a conveying direction, and being hingedely connected by hinge pins extending transversely 5 to the conveying direction, at least one row of modules comprising two transversely adjoining modules that, at their facing end sections, comprise a central portion with transversely spaced forwardly extending link ends, and transversely spaced rearwardly extending link ends, the forwardly and rearwardly extending link ends being transversely staggered relative to each 10 other, the central portion of the first module at the interspace between the last two adjacent link ends of the end section being provided with a product support shelf, and the central portion of the second module at the last two adjacent link ends of the end section being free of a product support shelf, while the central portion of the second module at an end extending beyond the 15 opposite link end being provided with a connecting shelf that forms a continuation of the product support shelf at the interspace between the adjacent link ends of the first and second modules. Providing the central portion of the second module at the end extending beyond the opposite link end with a connecting shelf that forms a continuation of the product support shelf 20 at the interspace between the adjacent link ends of the first and second modules allows intermediate modules without a product support shelf to be used with end modules that are designed for use with intermediate modules with a product support shelf, thus significantly saving on tooling costs for belts having this basic design. In addition, the provision of the connecting shelf 25 allows the modules to be mounted in the belt only with the connecting shelves facing upwards, as the connecting shelves would otherwise get caught on the supporting surface of the belt during operation.
The provision of a connecting shelf to the second module is not obvious, at it complicates the structure of the modules, and reduces the open 30 area of the body of the conveyor belt.

The publications cited in the novelty search report, for example US 7070438, do include a product support surface, but this surface is part of the body portion and not a product support shelf, i.e. a thin walled structure extending from the body portion.
5 Further embodiments of the invention are defined in the appended claims.
The invention shall be explained with the aid of a non-limiting exemplary embodiment, which is shown in the appended drawings. In the drawings: 10 Fig. 1 shows a top view of a modular conveyor belt according to the invention;
Fig. 2 shows a perspective top view of an intermediate module of the belt of Fig. 1,
Fig. 3 shows a detail of the top surface of the belt of Fig. 2, and 15 Fig. 4 shows a bottom view of the intermediate module of the belt of
Fig. 1.
The drawings are schematical representations and similar or identical parts have been provided with the same reference numerals.
Fig. 1 shows a modular conveyor belt 1. The conveyor belt 1 20 comprises a number of rows 2 of modules 3 succeeding each other in a conveying direction 4. The rows 2 of modules 3 are hingedly connected by hinge pins 5 extending transversely to the conveying direction. At least one row 2a of modules comprises two transversely adjoining modules 3a, 3b. These adjoining modules, at their facing end sections 6, comprise a basic layout with 25 central portion with transversely spaced forwardly extending link ends 8, and transversely spaced rearwardly extending link ends 9. In this exemplary embodiment, the central portion 7 is corrugated, but may e.g. alternatively be embodied as a straight central portion. The forwardly and rearwardly extending link ends are transversely staggered relative to each other. As 30 shown, the link ends 8/9 are provided with rounded drive surfaces 18 for 4 cooperation with teeth of a sprocket wheel. In the embodiment shown, the rounded drive surfaces 18 form part of a cylindrical plane.
Two end modules 3a each transversely adjoin an intermediate module 3b with their inward facing end sections 6. The central portion 5 of the 5 first module 3a, here embodied as an end module, is at the interspace 10 between the last two adjacent link ends 11 of the end section 6 provided with a product support shelf 12. The central portion 5 of the second module 3b, here embodied as an intermediate module, has a central portion that at the interspace between the last two adjacent link ends 11 of the end section 6 is 10 free of a product support shelf.
In accordance with the invention, the central portion 7 of the second, intermediate module 3b is at an end 13 extending beyond the link end 14 opposite to the last two adjacent link ends 11 provided with a connecting shelf 15. The connecting shelf 15 forms a continuation of the product support shelf 15 12 at the inter space 16 between the adjacent link ends 17 of the first and second modules 3a, 3b.
The opposing side of the second module 3b is at an end extending beyond the opposite link end provided with a further connecting shelf 15. This way, the intermediate modules 3b can then be juxtaposed so that their 20 connecting shelves 15 connect, or can be adjoined with an end module 3a at either side.
It shall be clear to the skilled person that the invention is not limited to the exemplary embodiment discussed above, and that variations are possible within the scope of the invention as defined by the appended claim.
