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.

A logistics warehousing system includes a conveying device, a plurality of delivery containers, and at least one packing station. The conveying device includes an circular conveyor surrounding a central area. The circular conveyor circulates cyclically relative to the central area. The plurality of delivery containers include at least one first delivery container and at least one second delivery container different from the first delivery container. The plurality of delivery containers are placed on the circular conveyor and circulate along a circular track around the central area cyclically as the circular conveyor circulates. One of the packing stations receives one of the plurality of delivery containers from the conveying device.

A curved belt conveyor includes a supporting structure having a base for supporting the conveyor on a floor and a curved top portion engaged to the base. The curved top portion defines at least one curved advancing plane for one or more objects and/or articles to be moved along a curvilinear advancing path and has an arched wide side and an arched narrow side opposite each other. An endless conveyor belt is operatively engaged to the curved top portion to define the curved advancing plane and the conveyor belt is at least partially around at least two revolving rollers rotatively engaged to the curved top portion. At least one of the rollers is movable relative to the other between a distant position, wherein the conveyor belt is under tension and not removable from the rollers and a close position, wherein the conveyor belt is loose and removable from the rollers.

A curved belt conveyor includes a conveyor belt with a hooking element associated with an outer periphery of the conveyor belt and multiple pairs of rollers guiding the hooking element. A plurality of supporting elements is placed at the outer periphery, each for supporting at least one pair of rollers. A holding space for the hooking element is defined among each pair of rollers and a corresponding supporting element. A main roller of one of the pairs of rollers is movable along a trajectory extending along a longitudinal development of a corresponding main roller shaft between a releasing position, wherein the rollers are spaced to define an intermediate space therebetween to allow the passage of the hooking element, and a retaining position, wherein the rollers are close to each other to prevent passage of the hooking element from the corresponding holding space through the corresponding intermediate space.
