Patent number: 6758329Abstract: The invention provided a conveyor belt, which is special in that the belt in a direction perpendicular to the traveling direction of the belt is made from one single chain link, and that the transport top surface comprises a wide main portion and the top part of the eye projections which are flush with the main portion, such that the belt surface is substantially without apertures and/or openings and further that the hinge-like assembly arrangement is fully accessible only from the underside of the belt. By this inventive chain link is achieved that the narrow gaps between each assembled chain link in the prior art is not present such that from a hygienic point of view it becomes much easier to clean the entire conveyor belt satisfactory in that for each chain link, which usually constitutes 40-60 mm of the total length of the conveyor belt, which altogether, especially for deboning lines, might be 300-400 meter long, no gaps are present.Type: GrantFiled: May 28, 2003Date of Patent: July 6, 2004Assignee: uni-chains A/SInventors: John Haue Damkjær, Poul Erik Damkjær

Patent number: 6662938Abstract: The invention provided for a conveyor belt wherein chain links are assembled such that eye parts are inserted into the intervals between two eye parts in the opposite chain link, whereafter the transverse rod according to the invention is inserted from one side of the conveyor belt through the overlapping openings in both chain links. When the notches provided on the transverse rod adjacent the head portion come into contact with the end face of the chain link, i.e. the side of the chain link, the notches can be brought into engagement with slits provided in the outmost chain link by twisting the head portion and pushing it into the end portion of the chain link. When the notches are engaged in the slits the transverse rod is fixated such that it will not move sideward in relation to the longitudinal direction of the conveyor belt.Type: GrantFiled: June 26, 2002Date of Patent: December 16, 2003Assignee: uni-chains A/SInventor: Poul Erik Damkjaer

Patent number: 6412625Abstract: A feed apparatus (1) comprising a conveyor belt (2), the conveyor belt (2) comprising modules (3) with an upper (4) and a lower (5) surface, the modules (3) comprising hinge eyes (7) pivotally hinged to each other perpendicular to the feed direction. The feed apparatus (1) comprises at least one rotatable and toothed driving wheel (8) meshed with the conveyor belt (2), with the pressure receiving surface (10) of the teeth wholly or partially in contact against at least the outer surface (13) of its own hinge eye (7). Therefore an optimum force transmission to the belt itself is achieved, which occurs through the teeth of the sprocket wheel applying driving force at the hinge eyes, thus making the force transmission occur close to the center line of the axis of the hinge eyes. There is a good lateral steering of the belt, so that the risk that the belt hops off the toothed wheel is minimized.Type: GrantFiled: October 12, 2001Date of Patent: July 2, 2002Assignee: Uni-Chains A/SInventor: Poul Erik Damkjaer

Publication number: 20020011401Abstract: A feed apparatus (1) comprising a conveyor belt (2), said conveyor belt (2) comprising modules (3) with an upper (4) and a lower (5) surface, said modules (3) by first means (6) comprising hinge eyes (7) being pivotally hinged to each other perpendicular to the feed direction, and that the feed apparatus (1) in addition comprises at least one rotatable and toothed driving wheel (8) meshed with the conveyor belt (2), and that the pressure receiving surface (10) of the teeth wholly or partially has contact against at least the outer surface (13) of its own hinge eye (7). Hereby an optimum force transmission to the belt itself is achieved, which occurs by means of the teeth of the sprocket wheel having their application of force at the hinge eyes, thus making the force transmission occur close to the center line of the axis of the hinge eyes, just as there is a good lateral steering of the belt, so that the risk that the belt hops off the toothed wheel is minimized.Type: ApplicationFiled: October 12, 2001Publication date: January 31, 2002Inventor: Poul Erik Damkjaer
