摘要： A support link for a self-stacking spiral conveyor belt, which includes a carrier on which a self-stacking spiral conveyor belt is supportable, a set of orthogonally arranged rolling elements connected to the carrier, in use to guide the carrier along a conveyor path and an interlink mountable onto the carrier. The interlink is connectable to a matched interlink of an adjacent support link through couplers disposed on opposing ends thereof, whereby the connection of a plurality of support links results in a support chain. Furthermore, there is provided a supporting frame defining the conveyor path on which the support chain is movable and a motor driving the support chain by means of a drive gear, which interacted with a drive interface disposed on each support link.

摘要： An accumulating conveyor comprises a conveyor belt successively follows a first helical track from a lower end thereof in upward direction to a location below an upper end thereof, a first bridge to a location at a second helical track below an upper end thereof, the second helical track in downward direction to a lower end thereof, a first set of auxiliary guides to the upper end of the second helical track, the second helical track in downward direction, a second bridge to the first helical track, the first helical track in upward direction to the upper end thereof, and the second set of auxiliary guides to the lower end of the first helical track. The bridges are synchronously movable along the first and second helical tracks for varying the effective lengths of the conveyor belt.

摘要： An active drive spiral conveyor belt system includes a drum configured to rotate about a drum axis, a plurality of modules, a plurality of cross-rods joining together the plurality of modules, and an infeed system. The drum can include a plurality of drive bars, each with a drive member extending therefrom, and spaced an arc length. At least some of the plurality of cross-rods or modules can include a drive end configured to engage with the drive members. The plurality of modules can be configured to be collapsible relative to each other and the plurality of cross-rods. The infeed system can be configured to collapse the spacing between adjacent drive ends prior to transiting into engagement with a cooperating drive member.

摘要： A spiral conveyor construction comprises an endless conveyor belt guided on a conveying path. At least a part of the conveying path surrounds a drive tower. Spaced along the periphery of the drive tower are arranged vertical engagement members. Additionally on a lower section of the drive tower adjacent blocks are provided, radially projecting further from the drive tower than the engagement members, and where the blocks are provided with a radially extending secondary rib.

摘要： A transport attachment (1) for a plate conveyor (100; 200) for conveying material includes a transport plate (50) for conveying the material on a transport surface (10) of the transport plate (50). A connection device (40) has a fastening element (42) for fastening the transport attachment (1) to a driven traction element (150) of the plate conveyor (100; 200). At least one lateral supporting surface (41) is used for laterally supporting the transport attachment (1) in a curve of the plate conveyor (100; 200).

摘要： The bottom tier (24) of a conveyor belt (22) arranged in a spiral stack (26) is supported by and driven by inner and outer drive chains (28) and (30). The inner and outer drive chains are supported on and ride along support rails (32) and (34). The inner and outer drive chains are driven by a drive system (35) composed of inner and outer drive systems (36) and (38), each including a drive motor with a drive gear engaged with the inner and outer drive chains. Each of the motors is controlled by a separate variable frequency drive unit (114) and (116) which in turn are controlled by a control system (44). The control system (44) also controls the operation of a lubrication system (40) that supplies lubricant to the drive chains.

摘要： A conveyor belt (36) is arranged in at least one spiral conveyor unit (32) or (34) is arranged in tiers forming at ascending spiral stack (38) and/or a descending spiral stack (40). A ceiling or top sheet (58) is positioned over the spiral stack. A circulation fan (60, 62) draws spent thermal processing medium laterally from the tiers of the spiral stack, up the exterior of the stack and across the top of the stack above the ceiling or top sheet and through a heat exchanger (64) located above the ceiling. The treated thermal processing medium is then routed across the remainder of the diameter of the spiral stack and then down the side of the spiral stack diametrically opposite to the circulating fan thereby to enter the spiral stack in a lateral direction diametrically toward the circulating fan. At least one opening (70, 100, 200) is formed in the ceiling between the heat exchanger and the diametrically distal end of the spiral stack from the circulating fan thereby to provide an alternative flow path for a portion of the thermal processing medium to enter the spiral stack from above, thereby resulting in more uniform treatment of the work product being carried by the conveyor of the spiral stack.
