A trolley conveyor. The trolley conveyor includes: a tubular rail track having a slotted opening at the top. A trolley chain installed to move in the rail track. A hanger is provided for suspending therebelow objects to be transported. The hanger includes a connector at the upper end thereof which extends downward to toward the center of the trolley chain. The trolley chain includes vertical and horizontal rollers in chain units, with vertical rollers in one chain unit and horizontal rollers in an adjacent chain unit. The chain units are pivotally connected for up and down and side to side motion within the track. While the trolley chain moves, the connector avoids contact with the ends of the slot in the track. Thus, the trolley conveyor prevents the generation of noise and foreign substances. Also, the trolley conveyor prevents transfer of dirt, oil, and debris to an object being transported.

A flexible element for conveying goods in a conveyor system is provided. The flexible element includes a base configured to form a top surface, a bottom surface and an intermediate surface; a conveying means detachably mounted on the top surface and; a toothed projection detachably mounted on the bottom surface; and at least one pair of wheels mounted on the intermediate surface. A conveyor system for conveying the flexible element is also provided.

A transport system has a mobile carriage for transport of products along a guide path that has a first guide profile and a second guide profile. A first pair of rollers is mounted rotatably on a first rotation shaft borne by the carriage, so as to engage the first guide profile. A second pair of rollers rotatably mounted on the second rotation shaft engages the second guide profile. For each roller of the first pair of rollers and for each roller of the second pair of rollers, a reinforcing element is provided which is friction-coupled to at least a part of the main portions of external lateral walls of the rollers.

A roller modular conveyor belt module for motorized continuous conveyors includes first and second hinge elements extending from a main body along opposite directions orthogonal to the first direction and spaced from each other. Each of the hinge elements has a through hole with axis parallel to the first direction and being coaxial to each other to receive a respective hinge pin. The first hinge elements are adapted to interpose to second hinge elements of another module with through holes coaxial to each other to receive a hinge pin articulating therebetween. In the space between adjacent hinge elements, there is at least one roller passed through by an axial hole arranged coaxially with the through holes of the adjacent hinge elements delimiting the space. The module includes at least one bushing having an end portion inserted in the through hole, and extending through the roller axial hole.

A link conveyor for an assembly machine and methods for chordal compensation in a link conveyor, may include a first upper chordal compensation cam in the upper rail assembly at the first end of the frame to deflect the chain by a first upper variable deflection amount; a first lower chordal compensation cam in the lower rail assembly at the first end of the frame to deflect the chain by a first lower variable deflection amount; and configuring the first upper variable deflection amount and the first lower variable deflection amount to reduce deviation between a first velocity of the chain at the first end of the frame and a second velocity of the chain at the second end of the frame.

An upper surface of a main body section (10) is used as a placement surface (11) on which an article is placeable. The main body section (10) includes an intermediate section (12), a front section (13) adjacent to the intermediate section (12) on a front side (X1) in a front-rear direction (X), and a rear section (14) adjacent to the intermediate section (12) on a rear side (X2) in the front-rear direction (X). The intermediate section (12) is rectangular in a plan view, the front section (13) is shaped as a trapezoid that becomes smaller in a width direction (Y) while extending toward the front side (X1) in a plan view, and the rear section (14) is shaped as a trapezoid that becomes smaller in the width direction (Y) while extending toward the rear side (X2) in a plan view.

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.
