Embodiment Construction

[0019] Referring to the drawings, there is shown an improved take-up assembly 20 for a spiral conveyor 10 with a swing arm assembly mounted on its lower end, and two obstacle sensing subsystems 80, 130. At least one, both subsystems automatically shut down the drive motor 12 for moving the conveyor belt 10 when an obstacle is detected upstream or downstream of the tensioning assembly 20 . These obstacle sensing subsystems 80 , 130 are located on opposite ends of the tensioning assembly 20 and are designed to allow the normal collapse and extension movement of the conveyor belt 10 within the tensioning assembly 20 . When excess tension or warping motion of the conveyor belt 10 occurs just downstream or upstream of the tensioning assembly 20, one of these obstacle sensing subsystem sensors 80, 130 is activated, thereby automatically deactivating the drive motor 12 of the conveyor belt And the movement of the conveyor belt 10 is stopped.

Abstract

An improved take-up assembly used on spiral conveyor belt with interconnecting links. The improved take-up assembly is designed to prevent damage to the belt due to obstructions, excessive tension or excessive buckling. The improved take-up assembly includes a pivoting swing arm assembly coupled to an obstruction sensor that automatically shuts-off the drive motor used to move the conveyor belt when an obstruction is detected upstream from the take-up assembly. An optional obstruction sensor can also be used on the upper portion of the take-up assembly to detect obstructions downstream from the take-up assembly. Also disclosed is a buckling arm located above and longitudinally aligned with the belt and pivotally attached to the distal end of the lower swing arm assembly. The swing arm is also designed to pivot beyond the position where the first obstruction sensor is activated so that the amount of belt that continues to be drawn into the stack as the stack coasts to a stop.

Description

technical field [0001] The invention disclosed herein relates to self-stacking spiral conveyors commonly used in food processing plants, and more particularly to take-up assemblies for use with self-stacking spiral conveyors. Background technique [0002] Long spiral conveyor belts consisting of multiple interconnected links are often used in food processing plants. Such belts typically include mechanisms that accommodate changes in belt length due to the slumping and extending motion of the links, as well as normal wear and tear. [0003] More recently, tensioning assemblies built into the frame supporting the conveyor belt have been developed which are capable of collapsing sections of the conveyor belt in order to shorten the overall length of the conveyor belt. The tensioning assembly is positioned on a vertical path just upstream of the interior curve or bend. [0004] The tensioning assembly generally comprises a rectangular frame aligned longitudinally on straight, ...
