The present disclosure relates to an apparatus, a system and a method for driving a device for conditioning food products, such as, for example, meat, poultry, and the like, to improve their texture and improve consumer taste preference for the conditioned product when compared with an equivalent non-conditioned sample.
Mechanical blade tenderizers are commonly used by meat processors to cut through sinew and connective tissue when processing various cuts of meat and poultry. The process of cutting through sinew and connective tissue may increase the desirability of the resultant product, since consumers typically regard the product as more tender and delicious. Generally, when a blade-tenderized product is compared to a similar cut that has not been processed, the tenderized product is generally preferred by consumers by a wide margin (at least a 65% preference).
Currently, ratchet linkage assemblies are frequently used to drive mechanical blade tenderizers. These are complex systems with critical timing issues. The systems require the timing to be set or fined tuned with precision and expertise, requiring a high level of mechanical expertise for maintenance or repair. These systems do not typically include overload protection, so if a jam should occur in the tenderizer, one or more components of the tenderizer drive are likely to break, often a rod end or a linkage arm.
The present disclosure provides an apparatus, a system and a method for driving an indexing device that conditions or further processes food products (for example, non-intact meat and poultry products), such as, for example, a mechanical blade tenderizer, a cuber, a tender press, or injector, for conditioning food products, which provide increased reliability and reduced complexity. The disclosure also provides higher stroke rates as the motion is completed more quickly during each cycle of operation of the apparatus.
According to an aspect of the present disclosure, a driver is disclosed for a food conditioner. The driver comprises: a drive shaft that is configured to be driven by a motor; a continuous-to-intermittent converter that is configured to be coupled to the drive shaft; and a slip dutch that is configured to be coupled to the continuous-to-intermittent converter, wherein the slip clutch is further configured to disengage when a torque applied to the slip clutch exceeds a predetermined threshold. The continuous-to-intermittent converter may comprise a Geneva drive gear, or a Maltese Cross drive gear. The driver continuous-to-intermittent converter may comprise: a master drive gear coupled to the drive shaft; and a slave drive gear that is intermittently coupled to the master drive gear. The master drive gear may include a cam follower and wherein the slave drive gear includes a slot that is configured to receive the cam follower.
The slip clutch may comprise: an engager portion that is configured to drive a transporter; and a clutch portion that is configured to disengage the engager portion to cause the engager portion to stop rotation while the drive shaft continues to rotate substantially continuously. The engager portion may comprise a sprocket.

The drive unit may comprise a lifter. The driver may further comprise a cam unit that is coupled to the drive shaft.
According to a further aspect of the disclosure, a driver is disclosed for a food conditioner, wherein the driver comprises: a drive shaft that is configured to be driven by a motor; a master drive gear that is coupled to the drive shaft; a driven shaft that is configured to be driven by a force that is transferred from the master drive gear; and a slip clutch that is coupled to the driven shaft. The master drive gear may include a cam follower. The slip clutch may be configured to disengage when a torque applied to the slip clutch exceeds a predetermined threshold. The slip clutch may comprise: an engager portion that is configured to drive a transporter; and a clutch portion that is configured to disengage the engager portion to cause the engager portion to stop rotation while the drive shaft continues to rotate substantially continuously.
The driver may further comprise a slave drive gear that is coupled to the driven shaft. The slave drive gear may be configured to intermittently engage the master drive gear while the master drive gear continues to rotate substantially continuously. The master drive gear may comprise a Geneva drive gear or a Maltese Cross drive gear. The slave drive gear may comprise a slot that is configured to receive a portion of the master drive gear.
According to a still further aspect of the disclosure, a driver is disclosed for a food conditioner. The driver comprises: a drive shaft that is configured to be driven by a motor; a Geneva drive gear coupled to the drive shaft, the Geneva drive gear comprising a cam follower; a driven shaft that is configured to drive a transport; a Maltese Cross drive gear coupled to the driven shaft, the Maltese Cross drive gear comprising a slot for receiving and engaging the cam follower; and a slip clutch coupled to the driven shaft, wherein the slip clutch is configured to disengage when a force applied to the slip clutch exceeds a predetermined threshold.
According to a still further aspect of the disclosure, a driver may be provided for a food conditioner that includes a servo motor and a timing indicator. The driver may include a main drive, the servo motor, a slip clutch and the timing indicator. The timing indicator may be affixed to a rotating cam of the main drive to trigger servo shaft indexing.
