A direct drive spiral conveyor belt system that includes a drum configured to rotate about a drum axis and define a drive member, a belt configured to engage the drum and define a belt drive feature, and an engagement control ramp configured to rotate with the drum and selectively engage the belt. The engagement control ramp includes a first portion defining a first radial distance from the drum axis and a second portion defining a second radial distance from the drum axis, with the first radial distance being greater than the second radial distance. The second portion of the engagement control ramp is configured to selectively engage the belt and allow the belt drive feature to transition into engagement with the drive member as the drum rotates about the drum axis and the belt moves along the drum.

The invention relates to a positive drive spiral conveyor which includes, a drive tower rotatable about a vertical axis and a plurality of drive members extending in length from a bottom to a top of the drive tower. The drive members are spaced radially around the drive tower, with each drive member having a projecting driving ridge extending in length along at least a section of each drive member with a projecting shaft positioned on each drive member proximate an end of the driving ridge thereby defining an engagement zone. The projecting shaft defines a guiding surface around the shaft, such that in use a positive drive protrusion of a conveyor belt engages the guiding surface of the projecting shaft and is guided towards a leading side of the driving ridge.

A system for automatic organization, hanging and driving of slaughtered animals installed at the outlet of a slaughtered animals processing station such as a chiller. The system comprises a receiving and aligning means of slaughtered animals in longitudinal position, which is previously disposed to an accumulator device of slaughtered animals positioned longitudinally. The system further comprises a suspension and movement assembly of each slaughtered animal from the axial alignment assembly to a driving guide of each slaughtered animal to a hanging transfer device of each animal slaughtered in the hanging line.

Embodiments of the disclosure are directed to systems and methods for chain wear elongation measurement and drive compensation. In one embodiment, a chain system includes a chain including a plurality of links arranged in a continuous loop and having first measurement values for plurality of links and total chain length, wherein the chain is configured to rotate on a sprocket, and a chain elongation measurement system for counting the plurality of links of the chain and for determining total chain length to determine first chain elongation measurement values.

A spiral conveyor for positively driving a conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower.
