Christopher R. SIMPSON - Olney MD, US

International Classification:

B65G 15/64
B65G 39/16
B65G 23/06

Abstract:

A pulley assembly for an automative machine and methods for the same are disclosed. The pulley assembly may include a monolithic body, an actuation assembly, and a pulley. The body may define a recess extending from a first end surface toward a second end surface thereof. The recess may separate an upper portion from a lower portion of the body. The body may define a bore extending through the upper and lower portions of the body. The bore may be threaded along a length thereof. The actuation assembly may include a mechanical biasing element having a threaded portion. The mechanical biasing element may be disposed in the bore such that the threaded portion thereof is threadably coupled with the threaded portion of the bore. The pulley may be rotatably coupled with the upper portion of the body such that the pully moves when the upper portion is actuated.

B07C 3/00
B65B 43/54
B65G 65/00

Abstract:

Features for systems and methods for loading items into a tray are disclosed. The system may have an item conveyor configured to move the items towards a tray conveyor. The tray conveyor may be configured to move trays to receive items from the item conveyor into the tray. One or more sensors may detect the height of the items on the item conveyor and/or in the tray, and/or the position of the trays on the tray conveyor. A controller may receive data related to the one or more detected heights of the items and/or the position of the trays on the tray conveyor and correspondingly control movement of the item and/or tray conveyors for efficient loading of items into the tray and efficient movement of the trays for further processing. Tray conveyor movement sensors may detect movement of the trays or tray conveyors for further control or reliability of the system.
