A transfer device comprising an automatic lifting unit, the transfer device includes: a barcode reader for reading a barcode attached to a box accommodating a bobbin loaded with raw materials; a fork unit for chucking the bobbin; a traveling drive unit; and a control unit. The control unit controls Z-axis centering of the fork unit in conjunction with the barcode reader and the distance sensor, X-axis centering of the fork unit in conjunction with the chucking sensor, and Z-axis elevation and Y-axis movement of the fork unit, respectively, to automatically control lifting of the bobbin.

A delivery and storage device and a filament coiling device are provided. The delivery and storage device includes a device body, a plurality of storage bins, and a traveling assembly. The device body includes a chassis. The plurality of storage bins are disposed on the chassis and arranged in a direction parallel to the chassis. Each storage bin includes a stacking cavity and a pick-and-place opening formed in a top of the stacking cavity. The stacking cavity is configured to accommodate filament reels stacked in a direction perpendicular to the chassis and restrict the filament reels from moving in the direction parallel to the chassis. The delivery and storage device can effectively increase a number of filament reels stored, and is adaptable to an external loading and unloading mechanism which picks up a filament reel vertically.

A device for storing cylindrical material according to an embodiment of the present disclosure includes a rack shelf including one or more racks in which a circular axis is stored, a rack master including a first rack master fork configured to collect a first circular axis in which an article stored in a target rack is not mounted, and a second rack master fork configured to transport a second circular axis in which the article is mounted in the target rack from which the first circular axis is collected, a turn skid configured to collect the first circular axis collected from the first rack master fork; and an input/output port configure to mount the article in the first circular axis collected from the turn skid.

A creel assembly having an outer wall defines an interior space, a plurality of yarn package engagement locations distributed within the interior space, a gantry that is movable secured within the interior space, and at least one processor. The gantry is positioned to selectively engage yarn packages within the interior space. In use, the gantry can selectively access the plurality of yarn package engagement locations. The processor is communicatively coupled to the gantry and receives an input corresponding to a selected action by the gantry. Modular creel systems can be formed from a plurality of the disclosed creel assemblies. Methods of using and assembling the disclosed creel assemblies and modular creel systems are also disclosed.

A transfer rack is provided, including a rack, a pushing mechanism, and a stabilizing mechanism. The rack includes a base, a vertical plate, and hanging rods. The hanging rods are hierarchically hanged above the base. The pushing mechanism includes a push plate and a first power component connected with the push plate. The push plate has through-holes matched with the hanging rods, the push plate is slidably arranged on the hanging rods through the through-holes, and the first power component is provided to drive the push plate to move the goods to be transferred. The stabilizing mechanism includes support pillars, support beams, and second power components. The support beams cross the hanging rods under layers of the hanging rods respectively, two ends of one of the support beams are connected with the support pillars, and the support beams are lifted and lowered under driving of the second power components.
