A feed unit for articles includes a guide extending along a guide longitudinal axis to define a linear feed path for such articles. The guide is for accommodating articles arranged in a row one after the other and to guide the articles as the articles move along the linear feed path. The articles have a characteristic length corresponding to their size along the longitudinal axis. At least one segment of the guide is progressively rotated about the guide longitudinal axis by a total angle greater than 180° and with an angular variation per unit of linear measurement such that, substantially for each portion of the linear feed path equal to the characteristic length of the articles, the guide is rotated about the longitudinal axis by an angle greater than 4°.

A spiral chute having a center column assembly with a first center column segment is disclosed. The center column segment has a plurality of pairs of opposed apertures. The spiral chute also includes a plurality of chute assembly sections, each including a chute support arm, a chute section coupled to the chute support arm, an outer wall support coupled to a distal end of the chute support arms, an outer wall segment coupled to the outer wall supports, and a support arm bolt having a distal end and a proximal end. The distal end of each support arm bolt passes through a corresponding one of the first plurality of opposing apertures and engages a proximal end of the chute support arm such that the proximal end of the chute support arm abuts the first center column segment. A method of constructing a spiral chute is also disclosed.

A directed delivery system for drone delivery of an item to a location. The directed delivery system includes a receptacle to receive the item at the location, a container to receive the delivered item spaced some distance from the container in the vertical plane. A conduit lies between the receptacle and the containers that directs the item from one to the other minimizing the risk of damage during travel. Drone delivery of the item to the location is so that the item is received in the receptacle, and directed by the conduit to the container at the desired delivery point with minimal impact.

The present disclosure is directed to underwater seismic exploration with a helical conveyor and skid structure. The system can include an underwater vehicle comprising a sensor to identify a case having a hydrodynamic shape, wherein the case stores one or more ocean bottom seismometer (“OBS”) units. The underwater vehicle includes an arm. The underwater vehicle includes an actuator to position the arm in an open state above a cap of the case, or to close the arm. The underwater vehicle can move the arm to a bottom portion of the case opposite the cap. An opening of the case can be aligned with the conveyor of the underwater vehicle. The conveyor can receive, via the opening of the case, a first OBS unit of the one or more OBS units. The conveyor can move the first OBS unit to the seabed to acquire seismic data from the seabed.

With respect to a transfer facility configured to optimize package transfers therethrough, a container housing packages may be delivered to a first floor of the transfer facility. The packages may be transported to consolidation stations based on destinations associated therewith. In some examples, the packages may be bound for a single destination and thus transported to a single consolidation station. In some examples, the packages may be bound for multiple destinations and thus transported to a second floor of the transfer facility for sortation. A destination and mode of transportation associated with the package may be determined at an induction station on the second floor, as well as a consolidation station associated therewith. A drive unit may insert the package into a chute for transit down a slide to the consolidation station, where it may be placed into another container for shipment to the destination via the mode of transportation.

A system for assembling and installing a modular spiral chute includes a base support assembly having a plurality of rear rollers and a slot, where the slot is orientated in the base support assembly to receive a vertically positioned stanchion of the modular spiral chute. The system also includes a removable roller clamp having a front roller and configured to be inserted into the slot to form an aperture in the base support assembly to encircle the stanchion so that when the roller clamp is inserted into the slot the stanchion is rotatably secured vertically within the base support assembly between the plurality of rear rollers and the front roller. In addition, the system includes a caster mounted plate positioned on top of the base support assembly and configured to increase stability of the stanchion when secured within the base support assembly.

A rotational device is provided that reorients a container from a first orientation to a second orientation in a manufacturing line and receives and reorients containers with different dimensions. The rotational device has an enclosed passageway defined by four continuous, turning surfaces that contribute to the ability of the rotational device to receive and reorient containers with different dimensions. In one embodiment, the passageway of the rotational device rotates 90 degrees in a clockwise manner. The bottoms of the different sized container are aligned with a right edge of an entrance of the passageway that corresponds to a surface that turns and defines the bottom edge of an exit of the passageway. Thus, the rotational device can receive containers with different dimensions while reduces the movement or jostling of the containers within the passageway.

A spiral chute having a center column assembly with a first center column segment is disclosed. The center column segment has a plurality of pairs of opposed apertures. The spiral chute also includes a plurality of chute assembly sections, each including a chute support arm, a chute section coupled to the chute support arm, an outer wall support coupled to a distal end of the chute support arms, an outer wall segment coupled to the outer wall supports, and a support arm bolt having a distal end and a proximal end. The distal end of each support arm bolt passes through a corresponding one of the first plurality of opposing apertures and engages a proximal end of the chute support arm such that the proximal end of the chute support arm abuts the first center column segment. A method of constructing a spiral chute is also disclosed.

The storage-and-retrieval cell for a parcel-handling logistics platform includes shuttle robots that position parcels in storage locations and that retrieve the parcels therefrom, which locations form two rows of storage locations that extend along a longitudinal direction, and four half-rows of storage locations that are disposed back-to-back in the longitudinal direction between the two rows, a hopper being open in the upper floor between one pair of half-rows and the other pair of half-rows, the hopper being designed to allow the parcels to pass through it while they are being retrieved, the cell further including nesting trolleys each of which is suitable for being hitched to a shuttle robot and which are suitable for nesting together in the same storage location, and, at the edge of the hopper, an unloading device for unloading a nesting trolley by sweeping its deck.

An improved modular chute comprising a stanchion comprising a plurality of rib connection points; a plurality of rib assemblies extending from the stanchion, each of the rib assemblies comprising at least a first rib, a second rib, and a tie rod connecting the first rib to the second rib; and a lining disposed within one or more of the rib assemblies, wherein the lining comprises a plurality of lining sections.
