A method of installing pre-molded seal caps onto fasteners that extend from a surface comprises sequentially delivering the pre-molded seal caps, arranged on a carrier strip, to a plunger mechanism via a feed system. The method also comprises sequentially removing the pre-molded seal caps from the carrier strip using the plunger mechanism, operating in concert with the feed system. The method further comprises individually installing the pre-molded seal caps onto selected ones of the fasteners using the plunger mechanism.

A modular conveyor belt module includes a base body extending along a first direction transverse with respect to the transport direction, between two opposite lateral faces. The module includes upper and lower surfaces; two opposed longitudinal edges; hinge elements projecting respectively from the two edges along a second direction. Each of the first and second hinge elements is crossed by a first and second hole, respectively, the axes of the holes being parallel to the first direction. The holes are each coaxial to each other. The first hinge elements interpose the second hinge elements of another module with the respective holes coaxially aligned. The hinge elements are interposed to each other leaving free spaces to receive a roller. Each roller projects with a portion from the upper surface, the plane parallel with respect to the two directions and tangent to the portion of the rollers projecting from the upper surface.

An end effector for installing pre-molded seal caps onto fasteners comprises a cap-dispenser assembly and a cap-placement assembly. The cap-placement assembly comprises a main housing and a plunger mechanism, comprising an outer plunger housing and an inner gripper. The inner gripper is rotatable relative to the outer plunger housing between a cap-retaining configuration and a cap-releasing configuration. The plunger mechanism is selectively translatable from an extended position to a retracted position and from the retracted position to the extended position. The main housing is selectively rotatable from a cap-receiving position, in which the plunger mechanism is aligned with the seal-cap-delivery-sleeve central axis, to a cap-installing position, in which the main housing is angularly displaced from the cap-receiving position, and from the cap-installing position to the cap-receiving position.

A conveyor for transporting and elevating articles and a method and system for conveying articles up inclines is provided. The conveyor has a conveyor belt and a plurality of support elements extending outward from the article-conveying surface of the conveyor belt advancing upward along the incline. The conveyor may be positioned at an inclined angle relative to the horizontal ground, i.e., between about 5° and 85° or the conveyor can be substantially vertical, i.e., about 90° relative to the horizontal ground. The support elements prevent conveyed articles from sliding down the conveyor belt on the inclined conveyor and carry and hold articles on substantially vertical conveyors. The article-conveying surface of the conveyor belt may provide a low-friction retention surface to articles leaning away from the conveyor belt on the incline.

A sealing system which is designed to leverage the centrifugal acceleration of solids and liquids due to the natural rotation of the roller, expelling them outside, preventing most of the contamination from trying to penetrate the roller seals. Excess of contaminants that is not centrifugally expelled is blocked by the following internal sealing system.
