The cutter assembly 110 is positioned between the in-feed conveyor 106 and the takeaway conveyors 108 and 109. The takeaway conveyors 108 and 109 can be adjustably mounted to the frame by the adjustable conveyor mounts 207 and 206. The in-feed conveyor pivot mount 205 and the adjustable support member 204 allows the in-feed conveyor to be pivoted to adjust its slope such that the in-feed conveyor is positioned and has the optimal slope to properly feed the whole muscle product into the cutter assembly along the line of entry. Adjustable mount 206 and 207 allows the takeaway conveyors 108 and 109 to be raised or lowered for appropriate positioning to receive the sliced product for conveying away from the cutter assembly 110. The cutter assembly can also be raised or lowered on the cutter support assembly 210. The assembly 110 has a support frame 208 for the pinch roller and the cutter. All conveyors can also be adjusted longitudinally along the same axis that the product travels to facilitate loading and unloading.
These various adjustments of the conveyors and the cutter assembly allow for optimizing the in-feed of the product into the cutter assembly 110 and the taking away of the sliced product. The slope or angular rise or incline above horizontal in the direction of conveyance of the in-feed conveyor can vary to optimize feeding the product into assembly 110. The height of conveyors 108 and 109 can vary to optimize diverting the sliced product onto the conveyors 108 and 109. The height adjustment along cutter support assembly 210 of the cutter assembly 110 can also optimize in-feed and take-away. The in-feed conveyor can also have a conveyor belt having a dove tailed surface for feeding into the cutter.

The cutter 308 or rotatable cutting roller has a plurality of circular dove-tailed blades 310 for slicing the product into thin slices as it is fed through the cutter assembly. The circular dove-tailed blades 310 are spaced apart along the length of the cutting roller forming a cutting vane. The space 316 between adjacent blades defines the width of the product slices. The circular blades extend radially outward from the cutter roll. Multiple circular blades create a cutting vane or cutting fins along the length of the cutting roll. This creates spaces between the circular blades along the cutting vane. The pinch roller can also have radially extending circular ribs along its length that can extend into the spaces between the circular blades in a dovetailed manner.
The cutter assembly can further include an upper finger bar comb 302 which is mounted on one side of the cutter 308. The upper finger bar comb has a plurality of teeth or fingers 320. The upper finger bar comb can be positioned such that the fingers extend into the space between the circular cutter blades 310 for diverting the sliced product onto a takeaway conveyor. The lower finger bar comb 304 also has a plurality of fingers 318 or teeth that extend into the spaces 316 between the plurality of circular blades that are spaced along the length of the cutting roller. The upper finger bar fingers can be configured such that the fingers extend into every other space between the circular blades of the cutter and the lower finger bar fingers can be configured such that the fingers extend into the alternate spaces between the blades.

The side view further reveals the circular shape of the cutter blades 310. This side view also reveals the mounting arrangement of the upper and lower finger bars 302 and 304 respectively. Slotted adjustable mount 412 allows the lower finger bar comb 304 to be mounted closer to or further from the cutter 308. The upper finger bar 302 is mounted onto mounting bracket 406 and secured by a stiffening plate 324. The lower finger bar 304 is mounted on mounting bracket 414. Mount 412 allows the lower finger bar comb 304 to be mounted closer to or further from the cutter 308. The shadow lines showing the cross sections of the two finger bars show how the fingers of the finger bar combs extend between the circular blades of the cutter. The support frame 208 for the cutter and pinch roller is also shown. The reason for having two sets of combs (or alternatively one comb with two sets of fingers having alternating bends—see
The fingers of the upper finger bar comb can be operable to divert a first set of sliced product onto a first take-away conveyor and the lower finger bar comb can be operable to divert a second set of sliced product onto a second take-away conveyor. The fingers of the upper finger bar and the fingers of the lower finger bar can be configured to extend into alternate spaces between the cutting blades. The embodiment as shown has stacked take away conveyors, which can best be seen in

The process begins by conveying a whole muscle product toward the cutter assembly 110 with the in-feed conveyor 106. the whole muscle product is conveyed along a path to engage the cutter assembly at the interface 326 of the pinch roller 306 and the push roller 307. The pinch roller 306 having a ribbed roll surface 312 and the push roller 307 having a textured roll surface 314 comprising teeth dove-tailed in relationship to the rib surface of the pinch roller grasps the whole muscle product and pushes the product through the cutter assembly. The whole muscle product is fed along a line of entry 201 or line of engagement into the engagement interface 326 of the pinch roller and the push roller. The whole muscle product is advanced to engage the cutter 308 or a rotatable cutting roller having a plurality of circular of dove-tailed blades or fins along the length of the cutting roller. The circular dove-tailed blades 310 are spaced apart along the length of the cutting roller forming cutting fins along the length of the roller. The whole muscle product is cut into product slices having a width defined by the space between adjacent cutting blades.
With the two finger bar embodiment, the fingers or teeth of the lower finger bar 304 will engage every other slice and divert every other slice to the lower takeaway conveyor 108. The slices that are diverted to the lower conveyor are then conveyed away from the cutter assembly for further processing. The remaining slices are then diverted by the fingers or teeth of the upper finger bar 302 onto the upper takeaway conveyor 109. The takeaway conveyor 109 will then convey the sliced product away from the cutter assembly for further processing. The process is such that immediately adjacent product slices are diverted to separate takeaway conveyors such that when the product slices are diverted to the takeaway conveyors there is adequate spacing between the product slices such that they do not adhere to the adjacent slice. This spacing facilitates further down line processing whereby the operator does not have to manually separate edges and slices.
With regard to the single comb embodiment, the single comb is designed with two separate sets of fingers or teeth that are bent or angled differently such that one set of teeth engages the meat slices prior to the second set of teeth. The single comb configuration performs the same task as the two comb configuration in that the first set of teeth diverts every other product slice to the lower takeaway conveyor and the second set of teeth diverts the remaining product slices to the upper takeaway conveyor.
In either the single comb or the two comb embodiments, the teeth of the comb extend into the space between adjacent cutting blades of the cutting roller. By extending into these spaces the fingers will engage the sliced meat product captured between the cutting blades thereby diverting the product slices. The angle 202 of the cutter assembly off-vertical and the line of engagement 201 of the whole muscle product facilitates diverting the product slices to an upper and lower conveyor. Addressing the cutter at two separate points of engagement diverts the cut product to the conveyors.
The approach angle or slope of the in-feed conveyor can also be adjusted to optimize the path of engagement for engaging the cutter assembly. The angle 202 of the cutter assembly can also be adjusted thereby adjusting the line of engagement 201 to optimize feeding a whole muscle product into the cutter. The relative height of the cutter assembly and the takeaway conveyors can also be adjusted in order to optimize the diverting or deflecting of the product slices onto the upper and lower conveyors. The two finger bar system shown in
The deflection point 424 is the location where the first set of fingers addresses the cutter and deflects product slices onto the lower takeaway conveyor. The second deflection point 426 is where the second set of fingers addresses the cutter and deflects the remaining product slices onto the upper takeaway conveyor.
The shadow lines of the push roller and the pinch roller shown in
The rotation of the cutter and the rollers are affected a motor 114 and belt system. The motor is sufficient to drive the whole muscle product through the cutter to be deflected onto the takeaway conveyors.
The single finger bar 303 has elongated mounting slots 1404 and 1406 for lateral adjustment. The finger bar length 1402 transitions to the main panel of finger bar 1408 having the first set and the second set of fingers extending therefrom 1414 and 1412 respectively. The fingers extend from the main portion of the finger bar to a 45 degree bend 1410 and continues along a straight line 1418. The first set of finger bar fingers 1414 or teeth continue along that line however, the second set of finger bars 1412 makes an additional bend at 1416 and then extends along a straight line.
The positions of the in-feed conveyor, the cutter assembly, and the take-away conveyor can be adjusted to optimize the in feed of product along the line of entry and the diverting of the product onto take away conveyors. As discussed above, the whole muscle product to be sliced can be flattened to the appropriated thickness to allow travel between the pinch roller and the cutter. The product can be placed on the in-feed conveyor for conveying the flattened product along the line of entry for engagement with the cutter.
The push roller can engage the product and push it through the interface between the pinch roller and the cutting roller. The pinch roller engages the product and pinches the product against the cutting roller and pulls the product through the pinching engagement. As the product travels through the cutting roller the product is sliced into thin slices. The upper and lower finger bars having fingers extending between the blades of the cutter can then divert separate alternate first and second sets of sliced product onto first and second take-away conveyors. The take away conveyors can take away the sliced and separated product slices to the next stage of processing. The same can be accomplished with a single finger bar having fingers or teeth extending between each of the blades where adjacent fingers alternate with different bends thereby addressing the cutter at different points.
The various cutter and separator apparatus and method examples shown above illustrate a novel method for separating the slices as the slices travel through the cutter. A user of the present invention may choose any of the above cutter and separator embodiments, or an equivalent thereof, depending upon the desired application.
