Abstract

Modular conveyor (1) being assembled from a kit of standard components, said conveyor having a length, width and height, where the conveyor at least comprises:•a. four end side plates (2-5), where each end side plate is provided with an aperture (6) which aperture is suitable to accommodate a sprocket wheel axle (7,8);•b. two sprocket wheel axles (7,8), where at least one axle is suitable to be connected to drive means (9), where each axle may accommodate one or more sprocket wheels;•c. web elements (13), which elements are attachable to one side of the side plates (11,12), in order to keep pairs of side plates at a determined lateral distance, where said web elements further comprises means for supporting an endless conveyor belt;•d. an endless conveyor belt arranged around the sprocket wheels.

Claims

1. Modular conveyor being assembled from a kit of standard components, said conveyor having a length, width and height, where the conveyor at least comprises:

a. four end side plates, where each end side plate is provided with an aperture which aperture is suitable to accommodate a sprocket wheel axle;

b. two sprocket wheel axles, where at least one axle is suitable to be connected to drive means, where each axle may accommodate one or more sprocket wheels;

c. web elements, which elements are attachable to one side of the side plates, in order to keep pairs of side plates at a determined lateral distance, where said web elements further comprises means for supporting an endless conveyor belt;

d. an endless conveyor belt arranged around the sprocket wheels.

2. Modular conveyor according to claim 1, wherein side plates are provided, said side plates being connectable in either end to further side plates or an end side plate.

3. Modular conveyor according to claim 1, wherein pivot side plates are provided, where said pivot side plates are connectable to side plates and/or end side plates, where the pivot plates have means for allowing adjacent side plates or end side plates to be arranged at an inclination or declination relative to an adjacent end side plate or side plate, and optionally further means are provided in said pivot plates for guiding the endless conveyor belt through the change in elevation.

4. Modular conveyor according to claims 1, wherein one or more turn modules are provided, where said turn modules have a set turning radius and are provided with an inner curved side and an outer curved side having a predetermined distance between said inner and outer curved sides, such that ends of the inner and outer curved sides are attachable either to further turn modules or to side plates or end side plates, and where web elements are arranged between said inner and outer sides, and where means are provided in said inner and outer sides for connecting to side plates or end side plates.

5. Modular conveyor according to claim 1, wherein said web elements are provided as modular elements in standard modular lengths.

6. Modular conveyor according to claim 1, wherein the endless conveyor belt is assembled from a plurality of substantially identical modular belt links, and where the end side plates, the side plates, the pivot plates and the turn modules are designed in modular dimensions allowing the modular belt links to be assembled around the sprocket wheels in a fixed number of modules.

7. Modular conveyor according to claim 6, wherein elevation guide rails are provided where said rails has an I- or T-shape, where the top of the I or the T has an upper flange and a body extending substantially perpendicular from said flange, where the elevation guide rails are arranged in parallel pairs, such that the rails provide a slot between the upper flanges of the two rails, where said slot has a narrow opening upwards and a wider opening, between the bodies of two parallel rails, and where a hold down tab is provided in at least some of the modular belt links, where said hold down tab has a first section extending substantially perpendicular to the transport surface of the module, where said section may be accommodated in the slot between two rails, and where at a distal end of the section a flange is provided said flange extending perpendicularly from said section, and is accommodated between the bodies of two parallelly arranged rails.

8. Modular conveyor according to claim 1, wherein the apertures provided in the end side plates are oblong, allowing the sprocket wheel axle to move in the plane of the conveyor belt, and where adjustment and tightening means are provided interacting between said sprocket wheel axles and said end side plates.

9. Modular conveyor according to claim 1, wherein at least one end side plate is provided with means for attaching the drive means in the form of a sprocket wheel axle drive motor, said motor providing propulsion means for the modular conveyor.

10. Modular conveyor according to claim 1, wherein the web elements are either:

a. Plates, optionally provided with apertures having a length corresponding to the length of an end side plate, and a width corresponding to the desired width of the modular conveyor;

b. Plates, optionally provided with apertures, where said plates either have a length corresponding to the length of one or more side plates or one or more side plates and the length of an end side plate, and a width corresponding to the desired width of the modular conveyor;

c. Bars extending between side plates or end side plates, where said side plates or end side plates are arranged along opposite sides of the modular conveyor, where further a pair of bars are provided with a stabilizing element providing stiffness in the conveying plane.

11. Modular conveyor according to claim 1, wherein all plates and elements are assembled by snap fitting click mechanisms.

12. Procedure for assembling a modular conveyor comprising components from claim 1, wherein in

a. Two end side plates are arranged at a distance corresponding to the width of the finished conveyor in either end of the conveyor, said side plates defining the ends of two opposing sides of the modular conveyor structure;

b. Optionally a plurality of pairs of side plates are arranged between the end plates in either side of the modular conveyor, each plate connected to an adjacent plate;

c. Optionally pivot plates are arranged in the opposing sides of the modular conveyor sides, and elevation means are arranged as support for the elevated side and end plates;

d. Sprocket wheel axles and optionally sprocket wheels are fitted in the end plates in either end of the conveyor;

e. Web elements are arranged along the length of the conveyor

f. An endless conveyor belt is arranged between the sprocket wheel axles and/or wheels in either end of the conveyor, and the tension in the belt is optionally adjusted by the adjustment and tightening means;

g. Optionally a drive motor is fitted to one sprocket wheel axle.
