Abstract:
The invention provides a conveying apparatus including an upstream conveyor, a downstream conveyor oriented perpendicularly to the upstream conveyor to form a butt turn, and a mechanism for transferring conveyed articles from the upstream conveyor to the downstream conveyor. The transfer mechanism includes guide rails that provide a corner to change the direction of travel of the conveyed articles and a transfer assist conveyor for supporting the articles as they travel between the upstream and downstream conveyors. The transfer assist conveyor runs alongside the upstream conveyor and has a cantilevered section that extends over the sprocket location of the downstream conveyor to perform the function of a prior art static transfer plate.
Abstract:
Modular conveyor belt links have edge structure for occluding exit of pivot rods from the edge of the belt during operation of conveyor belts formed from pivotably connected end-to-end links. The links feature belt edge structure with an outer pivot rod entry aperture offset from the axis of aligned link end pivot rod holes in one set of link ends thereby forming a pivot joint axis. When the pivot rod is forced from the belt edge into the offset aperture and headed toward the pivot joint the plastic link is elastically deformed enough to permit entry of the rod. For example, an occlusion barrier wall disposed near the belt edge retains the rod in the pivot joint. A matrixing nest for the end of the pivot rod resident in its axial joint site is formed in the link material. From this nest the rod can be removed only by forced distortion of a rod end by a force greater than those forces encountered in the course of normal belt operation. Various embodiments are permitted by offset aperture and nesting structure that afford functional advantages in belt performance.
Abstract:
An automated work center for use in materials handling operations is disclosed. The work center includes a randomly accessible vertically moving temporary storage queue 11 for receiving containers 25 that hold material goods. A fixed loading ramp 20 is arranged to receive containers 20 from an external system and to load the received containers onto the storage queue 11. A work area 5 having a plurality of rotatable work tables 7 provides an gives the operator access to the containers. A delivery system 14 transfers containers between the storage queue 11 and the work tables 7 and a takeaway system 16 transfers containers between the work area and the conveyor network. An automated control system 17 coordinates the delivery of containers between the temporary storage queue 11 and the work area 5. A consolidation queue 18 having a multiplicity of vertically spaced shelves may be disposed opposite the work tables 7 to facilitate the consolidation of ordered goods.
Abstract:
Method of manufacturing, assembling and fabricating a woven-wire belt with unitary vertically-oriented lateral edge flattened-wire helically-wound surfaces along each lateral edge for dynamic-frictional drive of the belt by a rotatable substantially-cylindrical drive surface in a helically-curved path, free of any mechanical drive connection while in the helical path. Lengthwise-directed tension control of the belt is exercised, while the belt is exterior to the helically-curved path, to achieve desired frictional drive contact within the drive surface. An exterior travel path for the belt between exit from and return to the helically-curved path provides an endless belt travel array. Increasing belt movement from the helically-curved path to the exterior travel path is used to increase lengthwise-extended tensile stress in the outer perimeter of the belt, while in the curved path; the increase in tensile stress in the outer perimeter increases constrictive force transferred to the inner perimeter of the belt so as to increase dynamic-frictional drive force along the inner perimeter of the belt which is in contact with the rotatable substantially-cylindrical drive surface.
Abstract:
A conveyor belting comprising a plurality of like modules having a broad spectrum antimicrobial agent associated therewith, is described. The modules are of an integral molded construction and the antimicrobial agent is preferably a chlorinated phenoxy incorporated into the polymeric material comprising the modules. The belting of the present invention is particularly useful for conveying and transporting foods including food processing and food handling applications.
Abstract:
A chain for conveying slices of a food product comprises a series of interlocking U shaped links each having a crossbar and two legs. The legs are provided with loops which partially surround the crossbar of an adjacent link. Some of the loops have an endpiece which is bent through at least 270.degree. and is provided with an elongated tip which extends appreciably from and at substantially right angles to the plane of the chain. These tips penetrate the slices and ensure that they are carried by the chain without slippage. Preferably each endpiece having a tip is adjacent the outer portion of a leg so that the mechanism for lifting the slice from the chain can operate in the closest possible proximity to the tip in order to reduce bending of the slice.
Abstract:
One aspect of this invention comprises an improved conveyance system comprises an endless flexible belt which circulates through at least two arcs, at least one gripping member attached to the belt, the gripping member having a free end and an anchoring end, and a biasing means which biases the anchoring end of the gripping member toward the surface of the conveyor belt, wherein the gripping member is open as it traverses an arced path and is closed as it traverses a straight path. A workpiece is loaded as the gripping member traverses the first arc, and offloaded as the gripping member traverses the second arc, Preferably, the first arc has a greater radius than the second arc. The inventive also comprises a heater utilizing the conveyance system.
Abstract:
A plastic modular conveyor belt of the type having slotted openings in one set of projections for allowing collapse of the inner side of the belt in travel around curves includes a guide roller on the underside of the belt. The guide roller, with a low-friction bearing, smoothly guides the belt so that contact is avoided at the inner side belt edge. In some preferred embodiments the guide roller can also serve as a hold down for the belt around curves, by engaging upwardly against a guide strip. In another embodiment separate hold down tabs are included, so that the roller serves only a guiding function.
Abstract:
A conveyor belt, particularly suited to the food processing industry, includes a tension-bearing framework of transversely extending rods connected to tension bearing interconnected links into which is attached a series of loose-fitting modular product support members. The product support modules include forwardly and rearwardly extending link ends such that successive modules are interfitted with one another. Each of the forwardly and rearwardly extending link ends are provided with slotted longitudinal openings through which the transverse rods extend. The distance between a front wall portion defining the slot in a forwardly extending link end and a rear wall portion defining the slot in an associated rearwardly extending link end is greater than the fixed longitudinal spacing spanned by adjacent transverse rods so as to permit some relative longitudinal movement between the conveyor modules and the rods. In addition, at least one of the modules and the rods are provided with standoff elements which define a minimum contact area between the modules and the rods. This limited contact area creates larger openings between the conveyor modules and the rods such that when the conveyor belt is passed through a washing unit, washing sprays can effectively reach all surfaces. In addition, since the conveyor modules are permitted to shift longitudinally relative to the rods, this further enhances the elimination of debris trapping zones such that a highly sanitary conveyor belt arrangement is obtained. In addition, unique end cap members are provided to prevent relative rotation between drive links associated with the conveyor belt and the transverse rods.
