Embodiments of the present disclosure provide a conveyer and a method of controlling the mentioned conveyer. In one embodiment, a conveyer includes: a support base; a roller assembly including a plurality of delivery rollers coaxially arranged, a plurality of lead screws and a plurality of screw motors respectively connected in a one-to-one correspondence with the plurality of lead screws, each of the delivery rollers being formed with at least one threaded hole, and being engaged with the corresponding lead screw of the lead screws through the threaded hole of the each of the delivery rollers; a driving shaft rotatably connected with the support base, the screw motors being provided on the driving shaft by fixing structures, wherein the delivery rollers are provided to be coaxial with the driving shaft; and a driver unit configured to drive rotation of the driving shaft.

An automated palletizer includes an automated package pick device capable of moving packages from a package deposit section to a pallet to form a pallet load from packages, a controller that is operably connected to the automated pick device, the controller having a pallet load generator configured to determine a pallet load structure of mixed packages, the pallet load generator being programmed so that it determines the load structure from mixed package layers overlaid over each other at least one of the mixed package layers being formed of stacks of mixed packages, top and bottom surfaces of the stacks corresponding to the at least one mixed package layer respectively forming top and bottom surfaces of the at least one mixed package layer that are substantially flat. The controller generates commands for the pick device to build the pallet load from the load structure determined by the pallet load generator.

A method and a device for individually supplying rollable discoidal components stocked in a reservoir in a supply position, wherein one component is respectively held in the supply position with the aid of a magnetic field of the device.

Respective items are retained as they are transported by mobile delivery mechanisms. An item to be delivered to a target storage location of a plurality of storage locations is positioned upon the carrying surface of a delivery mechanism. The carrying surface defines a retention zone bounded by a first wall, a second wall, a third wall and a fourth wall. At least one of the third wall or the fourth wall are displaceable to define an opening in the retention zone. The delivery mechanism moves from the location where an item is received to a location proximate the target storage location to facilitate transfer of the item through the opening obtained by displacing one of the third wall or the fourth wall. Irregularly shaped items are freeduring movement of the delivery mechanismto move upon the carrying surface and within the boundaries of the retention zone.

A method and a device for individually supplying rollable discoidal components stocked in a reservoir in a supply position, wherein one component is respectively held in the supply position with the aid of a magnetic field of the device.

A nut transporting device includes: an outer cylinder, multiple attracting members that are arrayed in a spiral shape about a center axis extending in an axial direction of the outer cylinder, on an inner surface side of the outer cylinder and that form a magnetic field on an outer surface side of the outer cylinder to attract a weld nut to an outer surface of the outer cylinder; a rotary drive unit configured to rotatably move the attracting members about the center axis; and a restriction guide that restricts rotational movement of the weld nut to move the weld nut axially along the outer surface of the outer cylinder.

A separation device for supplying and separating workpieces has a workpiece store, a first separation disc having first separation chambers, and a supply disc having workpiece guides, wherein the first separation disc is arranged such that it can be adjusted between a receiving position and a supply position relative to the supply disc, wherein in the supply position the first separation chambers are arranged flush with the workpiece guides, and wherein the first separation chambers are designed to supply workpieces arranged in the first separation chambers to the respective workpiece guides.

A fluid-floated conveying device includes a multi-channel space conversion cabin. An upper channel port is provided with a floating ball outlet gate which is communicated with a water pipe filled with a liquid. A side channel port is provided with a floating ball inlet gate communicated with the external atmosphere. A lower channel port is connected to a water storage pressure cylinder or a water discharging pipe. A floating ball carries articles and enters the cleared space conversion cabin from the side channel. The floating ball inlet gate of the side channel is closed, the cabin is filled with water, the floating ball outlet gate of the upper channel is opened, the floating ball rises and enters from the upper channel port, the communicated water pipe filled with the liquid, the water buoyancy enables the floating ball to rise, and the carried articles are conveyed to a receiving platform.

An ambulance cot loading and unloading system for an emergency vehicle includes a base for mounting in the emergency vehicle and an arm mounted for linear movement along the base, wherein the arm configured to support a cot while the cot is being loaded into or unloaded from the emergency vehicle. The ambulance cot loading and unloading system further includes an indicator mounted relative to the arm and a control system, which is in communication with the indicator and configured to generate a status indication of the cot loading and unloading system at the indicator.

A delivery system for transporting a golf ball from a first location to a second location has a transport track. The transport track has a first track and a second track. The first track has a first contact edge and a second contact edge configured to simultaneously contact a golf ball. The second track has a third contact edge and fourth contact edge configured to simultaneously contact a golf ball. The first track is positioned opposite the second track and is configured to fit a golf ball therebetween. The first track and the second track each have a repeating curvature that produces an undulating path for a golf ball between the first location and the second location.
