Modularized roll surface for moving article

Abstract

The invention discloses a modularized roll surface for moving an article on a conveying line or a base of a processor or for other application. The modularized roll surface comprises a support framework (10) preferably made of metal elements, and a roll bracket (11) with rolls (21) is buckled and inserted into the support framework. The grouped rolls of the bracket are arranged in the support framework, the disassembly operation of the rolls can be easily and elastically executed by using the structure of the framework, and the maintenance of the roll surface and the structural operation of anchoring the framework to the conveying line are convenient. Assembly of the grouped rolls of the bracket actually is easily realized through the specific configuration of the bracket and materials for manufacturing the rolls. Modularity of the roll surface is obtained by using specific connecting elements of the framework with the bracket; and the bracket with any proper length can be obtained.

Description

technical field [0001] The present invention relates to a roller plane for moving articles along conveyor lines, bases of processing machines, machines operated by gravity or other similar applications. Background technique [0002] The roller plane consists of rollers rotating according to a rotation axis perpendicular to the advancing direction of the article, wherein rollers having a diameter of about several centimeters and a substantially considerable length are gathered in a support frame containing a predetermined number of rollers. These can be mounted individually and directly on the frame or can be pre-collected in roller bearing brackets which are then inserted longitudinally into the supporting frame. [0003] In both solutions involving the mounting of the rollers individually in the frame and of the frame-roller group formation, there are operational difficulties when installing the rollers and when they are being maintained. [0004] An important consideratio...

Problems solved by technology

Thus for each lateral thrust applied to and transmitted from the roller to the frame, only one of the two sides resists the thrust; therefore, not only is the overall resistance of the roller plane to lateral stress lower, but the deformation of the stressed side will be actually present, this is enough to cause the pivot to leave the base associated to the other side, and therefore the rollers at the base of the frame will fall

[0006] Another limitation of prior art solutions manifests itself in permissible low load values ​​and excessive loads (even for short periods) that cannot be supported above low load values; under these conditions the pivot or roller-bracket breaks because the pivot Shafts and brackets are the main parts that will be stressed in the entire structure protruding between the sides of the frame

[0007] Finally, in known construction solutions, the various modules that make up the roller planes of the conveyor line consist of ends that lack mutual hooking

Thus if the connection between the two modules is carried out with the roller plane in the protruding area, additional specific means of rigid connection of the frames of the two modules must be provided which, among other things, must be able to ensure During this passage through the plane of the rollers, no step between the two modules occurs after deflection due to the weight of the item itself; this step could cause problems with the advancement of the item or could even cause surface damage to the item itself
