FIGURES 1-4 show an assemblage 30 of food-process line equipment 32 (which according to context, includes transfer conveyor 56) in accordance with the invention. Each individual machine 32 (which in general, the transfer conveyor 56 is a specific example of the machines 32 m general, and see FIGURES 7 and 8 and the discussion connected therewith) is preferably mounted on rolling riding gear 34. Preferably the whole assemblage 30 is riding on a set of parallel tracks 36, something like small gauge railroad tracks 36. However, the last machine on the left in these views is a fryer 38. It is substantially heavier and has more supply line connections that the other machines. It might be preferable to not roll it onto to tracks 36.
The food process line 30 is substantially housed in an elongated enclosure (eg., tunnel 40). The tunnel 40 isolates a compact environment for independent environmental control of the environment surrounding the food process line 30 within a larger environment. The larger environment might be a commercial food processing plant operating a plurality of food process lines 30 simultaneously (see, eg., FIGURE 12).
One food process line 30 might be utilizing an ingredient that might be considered an allergen to some people in the public. In order to contain the allergen from wafting over to other food process lines 30 and contaminating them, the food process lines 30 are enclosed and comparatively sealed.
The fryer 38 is left mostly exposed for the most part because ofthe heat it generates. It might not be good for the fryer 38 to house is in an enclosed environment, or it might heat the tunnel 40 too high and starting pre-cooking the food product when that is not wanted. It is also believed that soon after the food product enters the fryer 38, the allergens will have been set and pose little risk then of being a source of air borne contamination.
FIGURE 2 shows that the tunnel 40 comprises a construction of bellows-like soft materials 44 like a transparent or semi-transparent polymeric material supported on spaced mverted-U shaped wickets. The tunnel 40 can be cycled between OPEN (retracted) and CLOSED (extended) states.
-6337-71
FIGURES 3 and 4 shows the tuimel 40 comprising a chain of telescoped inverted~U shaped half-pipes 46 (eg., like car ports in the US) constructed of hard materials like stainless steel or the like. Some or all of which are provided with access doors and/or windows. FIGURE 4 shows this tunnel 40 that comprises a chain of telescoped half pipes 46 of hard materials can also be cycled between OPEN (retracted) and CLOSED (extended) states.
The tunnel 40 is elongated between an upline end 48 and a downline end 50. FIGURES 1-4 show the fryer 38 protruding from the downline end. The tunnel 40 has a partial end wall on the downline end 50 to form a close-fitting opening for the fryer 38 to extend through.
FIGURE 5 shows the end wall of the upline end 48 of the tunnel 40. The end wall is provided with an elongated slit through which a thin conveyor extends, introducing pieces of food product to the food process line 30. Presumably, the food product pieces are raw pieces (uncooked). Raw pieces of chicken and most meats (excluding shellfish) are not thought to pose much of a risk of being a source for air home allergens. Instead, the higher risk is with known ingredients or spices and the like in the coating materials. Indeed, a drum tumbler tumbling chicken pieces with dry particulate coating material is a pretty effective way to generate air borne particulate matter.
FIGURES 3 and 6 show duct work 52 and fans 54 to produce a slight negative pressure in the tunnel 40. The exhaust stacks 52 would preferably to connect to outdoor vents outside of the food process plant. Additionally, the narrow slits which are the inlets for the introduction for food product would be preferably surrounded by air nozzles providing a constant curtain of air blowing into the tunnel 40 (and into the negative pressure). This would provide an additional measure of containing the air borne particulate matter inside the tunnel 40 from escaping into the food process plant.
FIGURES 7 and 8 show a pivoting and reversibly expanding-contracting transfer conveyor 56 in accordance with the invention. There are several such transfer conveyors 56 shown in FIGURES 2 and 4.
-7337-71
A non-limiting example of a food process line 30 might comprise the following series of machines in a line. Let’s assume that the food product is chicken tenderi pieces which are going to pre-dusted with spices and perhaps flour, dipped in batter and bread-coated twice, then fried. Hence the given food process line 30 might comprise| the following series of machines:—I
- a loader of (typically raw) food product;i i
- a transfer conveyor (ie.₅ the first);i
- a tumbling pre-dust coating machine;'
- a transfer conveyor (the second);:
- a batter coating machine;ΐ
- a tumbling bread crumb coating machine; i
- a transfer conveyor (the third);
- another batter coating machine;
- another tumbling bread crumb coating machine;
- a transfér conveyor (the fourth); and
- a fryer (and likely a freezing and packaging process too).
It will be noticed in the above example that, the transfer conveyors follow dry coating processes, not wet ones (eg., the two batter coating machines). This keeps the transfer conveyor cleaner longer.
2Ö One aspect of operating food process lines 30 is that, since the output of the line is headed into the public food supply, the food process line 30 is subject to government , _; inspectors (typically the USDA the US). If the food process line 30 is found to fail an inspection, all the food product outputted by that food product is subject to recall:- or ' that is, all the food product outputted since the last washing of the food process line 30.
So if the food process line 30 is wash once a week, and failure is discovered at the end of the week, then a whole week’s worth of output product has to be recalled.
If in contrast, the food process line 30 is washed nightly, then the worst case scenario is that any recall will be limited to one day’s worth of output product.
Hence, in choosing how frequently to wash, there is a balance of equities such as follows:—
337-71 ~ 8- ra» the food process line 30 for as long as practical to optimize ra» time vs. down time (ie., down time as for performing washing operations);
versus,
- wash frequently to reduce the risk of having a huge recall.
It is an object of the invention to provide improvements for decreasing the downtime for washing operations, thereby increasing the appeal of washing frequently.
Given the foregoing, the transfer conveyor 56 comprises a carriage 58, a turret 60 and pivot hardware 62 interconnecting the carriage 58 and turret 60. The carriage 10 58 is meant to be stationed as securely as possible in one fixed position in a food process line 30. The drawings show the carriage 58 riding on a rail by U-notched wheels or casters 34 which have locks to prevent roiling or any movement whatsoever, to the extent practical.
The turret 60 comprises spaced side panels spaced between a relatively solid bottom panel and a table plane which is characterized by paraEel, longitedinallyelongated and laterally-spaced slide bars. There is a multiplicity of laterally extending rods, bars and/or axle shafts which extend between the spaced side panels, and give them rigidity. A subset of these comprise laterally extending coursechanging means 64 for stretching an endless conveyor belt 66 in a circuit around such course- changing 20 means, Example turning course-changing 64 means include without limitation rollers, pulleys or non-rotating nose bars and so on.
The endless conveyor belt 66 is preferably a wire mesh belt. Corresponding, the slide bars defining the table plane comprise low friction synthetic or polymeric materials. The endless conveyor belt 66 courses a circuit comprising an (upper) food 25 carrying run 68 and a (lower) return run.
FIGURE 8 shows better that the belt 66 courses around four course-changing means 64 (eg., laterally-extending rollers). The upper food-product carrying run 68
337-71
-9of the belt 66 changes courses at. opposite ends around respective nose rollers 70. The nose rollers 70 are held on movable brackets 72 which can be driven between extended and retracted by pinion gears 74 that mesh with respective rack gears 76 formed in the brackets 72. By movement of the brackets 72, this causes the transfer conveyor 56 to 5 expand and contract between expanded and contracted extremes. Each bracket 72 also moves outward and inward in tandem with the respectively proximate nose roller 70.
Hence each traveling bracket 72 and its respective nose roller 70 move back and forth as a unit when the transfer conveyor 56 is in transition between a contracted state and an expanded state.
The transfer conveyor 56 set up in an expanded state for food process line 30 processing operations. In contrast, the transfer conveyor 56 is converted to a contracted state for maintenance and/or washing operations. The transfer conveyor 56 in a contracted state can be pivoted without moving the machines immediately upline and downline from it. Those queued flanking machines can be left m place. When washing or maintenance is finished, the transfer conveyor 56 can be pivoted back and expanded such that the food process line 30 is quickly put back to its careful alignment. The pivot hardware 62 includes an annular bearing race.
FIGURES 9 and 10 correspond to FIGURES 2 and 4 respectively' the assemblage 30 of food-process line machines have been removed from the view, as for 20 perhaps re-building a different assemblage 30 of machines for processing a different food product, or else a similar or same food product in a different fashion. Indeed, FIGURE 11 shows a food process line 30 except composed of a different assemblage 30 of machines.
FIGURE 13 shows coating-material supply machine 78 providing a supply of 25 coating material to a food-product coating machine 32. Preferably the supply machine 78 would likewise be located inside the tunnel 40.
FIGURE 14 is a perspective view of the tunnel 40 of FIGURE 5. The tunnel 40 has a variety of access doors allowing workers inside, as shown in FIGURE 6.
FIGURES 15-18 are a series top plan block diagram views showing various 30 assemblages of machines for food process lines 30 as well as showing various
- 10337-71 arrangements of feedback control systems 80 in accordance with the invention receiving inputs of product weight at one or more positions along the line and outputting control signals to one or more coating machines along the line to raise or lower the applied coating-material weight io the food product undergoing coating processes along the line.
FIGURE 19 shows a food-product coating machine 32 deployed into an OPEN state for cleaning, and being attended by a floor-based washing robot 84 which rides on its own third track 82, with an overhead washing robot 86 idle at the moment. The washing processes under the automatic control of a controller 88, which sends various control instructions to the machines 32 and robotic washers 84,86 cooperatively, causing the machines 32 to lift hoods and conveyors 56 to better reveal themselves for washing, and/or pivot to various angles so that the washing robots 84,86 can aim at the machines 32 from various angles of attack.
It is an aspect of the invention to provide a maintenance robot 90 as counterpart to the floor-based washing robot 84. The maintenance robot 9Q could traverse on the floor-based third track 82 and could remotely do any of the following service including without· limitation:—
- check belt tension;
- adjust belt tension;
- change a belt;
- change a roller;
- change a bearing;
- change a shaft;
- change a shaft seal;
- change a sprocket;
- change a drive chain and/or other components of the drive system;
and so on without limitation.
Whereas it has been disclosed here that the machines 32, the floor-based washing 84 and maintenance robots 90 ride on floor-based tracks 36 or 82, and overhead tracks 82 for carrying robots 86 dangling from bridge cranes or the like, other 30 mobile transit options are possible without limitation, like dynamic positioning (eg.,
-11 337-71 how floating oil rigs position themselves), and so on and without limitation. That way, the parallel tracks 36 and perhaps even the turntables 62 can be dispensed with, and the machines 32 can drive themselves in 360° (degrees).
Another aspect of the invention is having a floor-based third track 82 running along the food process line 30. The third track 82 supports a floor-based traveling washing system 84, The robot 84 of the floor-based washing system runs on the track 82 alongside the food equipment to clean each machine 32 individually. Preferably this washing system 84 could operated while the tunnel 40 is CLOSED. Optionally, the combined ground-based and overhead washing systems 84 and 86 might do a rinse cycle while the tunnel 40 is CLOSED, then the tunnel 40 is OPENED so a final washΐ might be done with more robust equipment (like a miniature fire truck) or else be done manually.
FIGURE 20 is a perspective view comparable to FIGURE 1 except showing foe food-product loading operations at the beginning of the food process line 30 are housed;
in their own climate controlled room 92. FIGURE 21 shows better the induction of a negative pressure in both the tunnel 40 and auxiliary room 92,
FIGURES 22 and 23 show that some portions of the sidewalls of the tunnel 40 may be equipped with isolation gloves 94.
The invention having been disclosed in connection with the foregoing variations and examples, additional variations will now be apparent to persons skilled in the art.
The invention is not intended to be limited to the variations specifically mentioned, and accordingly reference should be made to the appended claims rather than the foregoing :
