Poultry processing hub and belt assembly

Abstract

This invention relates to a hub and belt assembly for driving a poultry de-feathering machine and more particularly to a multiple bearing heat dissipating hub driven by a serrated timing belt. The hub assembly incorporates seals along a drive shaft to reduce wear caused by dirt. The timing belt synchronizes multiple picking hubs and reduces the friction driving required. The combination of a heat dissipating hub and the placement of seals along the drive shaft within the hub minimize maintenance and replacement.

CROSS-REFERENCE TO RELATED APPLICATION [0001]This application claims the benefit of the following provisional application: U.S. Ser. No. 60 / 349,526, filed Jan. 18, 2002, under 35 USC 119(e)(i).FIELD OF INVENTION[0002]The present invention relates to the field of poultry processing equipment, particularly rotational hub and belt assemblies for de-feathering or plucking devices.BACKGROUND OF THE ART[0003]Poultry processing industries commonly use automated lines to kill, eviscerate, pluck and further process birds. Rotational devices are generally employed to facilitate continuity of process and to minimize labor. One of the most common poultry processing machines is a plucker or de-featherer. For many years devices incorporating a number of pliable fingers have been utilized to beat and pull the feathers from bird carcasses.[0004]In processing facilities, multiple finger-type plucking devices are used in sequence to fully pluck a carcass. Typical plucking processes incorporate opposi...

AI Technical Summary

Benefits of technology

[0009]The present invention provides a poultry processing machine, particularly a hub and belt assembly such as a feather plucking device that facilitates timed rotation of driven members while diminishing wear and breakage commonly associated with such equipment. More particularly the device is a poultry processing apparatus which comprises a hub having a flange portion, a boss portion, a pulley end and a central bore extending therethrough. A hub plate, attachable to the hub, has a flange portion and a hub plate shaft bore alignable with the central bore of the hub. A drive shaft is mounted transversely through the central bore and hub plate shaft bore; the drive shaft further is provided with a pulley end and a spaced-apart drive end. A first bearing is positioned on the drive shaft at the hub plate and a second bearing is positioned on the drive shaft at the junction of the flange portion and boss portion. A seal is preferably positioned adjacent each bearing and at the hub plate to effectively prevent foreign matter from wearing the drive shaft and bearings.

[0011]Designed primarily for ganged sets of plucking arms, the hub and belt system utilizes a heat dissipating hub housing journalled to a drive shaft, preferably with at least two independent sealed bearings, and a timing belt which allows operators to alternate time opposed pairs of plucker arms to avoid entanglement of the process poultry, hangers and the plucking heads.

Problems solved by technology

Due to the high cost of purchasing and maintaining individual motors, eventually hubs were spaced-apart in sequence so that a single motor could be used to drive multiple pluckers.

Single drive hub assemblies eliminated multiple motors but had several inherent problems.

Problems exist in that the smooth belts stretch and constant maintenance and attention is required to control the drive force.

Friction from belt slippage also accelerates wear and tear on hub assemblies, belts and motors.

However, it is common that the poultry being processed, or the shackles from which bird carcasses are suspended, become entangled or otherwise disrupt the plucker assembly.

When, for instance, a shackle becomes entangled in single plucker, continual force of the drive source will cause the chain to shear the sprocket of that plucker.

Further, problems in the plucking process can result in the jumping, or unwanted movement of the chain in relation to the sequence of hub gear assemblies.

These inexpensive systems are prone to failure and require significant maintenance due, in large part, to the intrusion of dirt, feathers and fecal matter into the moving parts.

Because of belt slippage and the friction imparted on a hub assembly by the belt, hubs wear very quickly and must be rebuilt or replaced on a regular basis.

Gear and chain drives require constant maintenance and because of shackle entanglement in pluckers result in the shearing of teeth from the sprocket.
