referring to fig1 through 15 , wherein like reference numerals refer to like components in the various views , there is illustrated therein a new and improved fruit and grape bin cleaning method and apparatus , generally denominated 100 herein . in accordance with the present invention the system includes a wash station 110 having a funnel 112 disposed at the bottom for collecting water that drains off bins 10 as they are washed in an inverted state . preferably , the bins or tanks 10 disposed in an inverted orientation in the wash station 110 are supported by a rack or a conveyor system 180 or frame on its rim 11 . the funnel 112 has an upper rim 112 a and terminates at the bottom end with orifice 112 b . it should be appreciated that a wash station 110 will generally have at least one of an integrated side wall to catch overspray and spatter , or a separate external screen . hence it is desirable , but not essential , that such integrated wall or separate external screen also drain to rim 112 a of funnel 112 . as grape picking bins , and other fruit picking bins , to which the invention is also applicable to , usually have a 4 × 4 ft . base , and are usually 2 or 4 ft in height , the dimension of the funnel rim 112 a should be larger than 4 × 4 ft . a screen 114 is disposed between the upper rim 112 a and the orifice 112 b of the funnel 112 . a water storage tank 120 is in fluid communication to receive effluent from funnel orifice 112 b . a pump 130 is configured to remove water from the storage tank 120 and transfer it under pressure via internal manifold 174 and exterior manifolds 172 and 176 to spray nozzles 116 where it emerges as a high velocity jet of water to clean bins 10 . further , an ozone source or generator 140 provides ozone gas to at least one portal 141 of a water source that is in fluid communication with the nozzles 116 . generally , water from storage tank 120 is pumped to one or more spray nozzles 116 that surround or traverse the inside or outside of the inverted tank or bin 10 . these preferably high velocity water jets or sprays first wash grosser debris and grape residue off of tank 10 which flows downward to drain to funnel 112 . the screen 114 disposed in funnel 112 to capture solid matter so that generally particulate free rinse water flows back to tank 120 . thus , this first rinse step , as it uses drain water that accumulates in tank 120 , is intended primarily to remove the solid and dried or syrupy grape juice residues . in the next step , clean water , such as from source 141 is used in a final rinse . in order to insure that the final rinse also kills if not totally removes yeast and bacteria , the final rinse water is optionally ozonated either in - line from ozone source 140 via conduit or line 143 . the system 100 may deploy a single pump , or multiple pumps depending on the inherent pressure of the water used in the rinse stage , or the need to achieve very high pressure in the initial knock down or debris removal stage . optionally , the water storage tank 120 is also ozonated to insure it does not harbor yeast and bacteria . the quantity of water from the repeated first and final rinses of bins will eventually fill tank 120 , which is periodically drained . usually such water , even if ozonated is considered waste , so it must be disposed of in a treatment pond 190 . deploying either the continuous ozonation in tank 120 or subsequent ozonation before emptying to the pond 190 reduces the biological oxygen demand ( bod ) in the pond . any subsequent ozonation optionally takes place in drain line that leads from tank 120 to wastewater pond 190 more preferably , the tank or bin 10 is rinsed on the outside via the spray nozzles 116 connected to an exterior manifold 172 and internally with spray nozzles connected to an interior manifold 174 . both the exterior manifold 172 and the interior manifold 174 , are optionally connected to receive water at valve 230 via a common line or pipe 170 . the interior manifold 174 , as shown in fig2 , is preferably an inverted u - shaped bar or pipe , of which the 3 sides of the u define a primary reference plane thereof . rinse or spray water preferably enters the manifold 174 from the terminal arms that extend from the middle portion of the u - shape to minimize a potential difference in water pressure and flow rate between the spray nozzles 116 distributed on the interior manifold 172 . the spray nozzles 116 are preferably selected and oriented such that the water spray there from fans outward substantially in this primary reference plane so that the collection of spray nozzles provides a substantially planar spray pattern that extends outward from the perimeter of the u - shape . alternatively the interior manifold 174 can also be in the shape of a “ d ” rotated 90 degrees counter clockwise , but with the spray nozzles 116 disposed on the rounded upward facing part of the “ d ”. in this configuration , water can be feed to the curved part of the d from either the center of the flat side , or the opposing terminals of the curved part of the “ d ”, or just one side of the downward disposed flat portion to provide for a uniformity of water pressure and flow rate from the spray nozzles 116 . this resulting water spray pattern 117 ( fig4 ) is not only effective in reaching all portion of the interior tank surface , but by sweeping over the surface in oscillatory fashion , is very efficient at providing an energetic stream that dislodges partially adhered particulate matter and concentrated sticky grape juices , yet is highly efficient at doing so with a relatively small quantity of water per bin that is washed . the interior manifold 174 , as shown in fig2 , is also configured to be disposed between 2 tracks 181 and 182 that together form a conveyor system 180 for transporting the bins 10 into the wash station 110 . since the width of the interior manifold , w ( defined by the length of the bottom portion of the u shape ) is less than the separation distance , s , between tracks 181 and 182 , the interior manifold 174 can rotate downward below the common plane of these tracks so that bins 10 can be transported in and out of the wash station 110 by the conveyor system 180 . in a more preferred embodiment , as shown in fig3 b , the exterior manifold 172 is also preferably an inverted u - shape , but has nozzles 116 that are inward facing from the side , and downward facing from the top . the inverted u profile of manifold 172 is dimensioned to straddle over bins 10 after they are transported into the washing station 110 . such an exterior manifold 172 can be engaged and transported by an overhead track or rail system 160 to be driven over the bin 10 in the transverse direction with respect to the transport direction of the bins 10 on conveyor 180 . thus , the front and back of the bins are washed by the water emitted from the laterally directed nozzles on the vertical portions of manifold 172 , while the top of the bin is rinsed by the downward facing nozzles on horizontal portion of manifold 172 . preferably , water is feed from the terminal end of the side or vertical arms of the “ u ” to provide a more uniform flow rate and water pressure at each of the nozzles 116 . furthermore , it is also preferable that the system 100 also provide 2 pairs of vertically oriented spray bars 176 and 176 ′, each having a vertical sequence of nozzle 116 just inside the entrance and exit portal of the wash station 110 so as to wash the exterior sides of bin 10 that are disposed in a plane that is aligned with the transport direction on conveyor 180 . the first set of spray bar pairs 176 provide a knock down spray as the bin is being transported into the wash station 110 , while the second pair 176 ′ provide a final clean up rinse as the bin 10 is being transported into the wash station 110 by conveyor 180 . in contrast , preferably the interior and exterior manifolds sequentially provide both the first or knock down spray , the water from which is directed to tank 120 , and then the final rinse while the bin 10 is stationary in the wash station 110 . the ozonated water from tank 120 can be used for the initial rise of bins 10 on the sides via spray bar pair 176 . it should be appreciated that the ozonation of the collected knock down spray and / or rinse water from funnel 112 can occur in tank 120 , as well as when or after tank 120 drains to the treatment pond 190 . it should be appreciated that additional screening filters than screen 140 may be placed anywhere in the flow of water from drain 112 b to nozzles 116 to remove debris that would clog the nozzles or otherwise interfere with efficient operation . the preferred placement and screening capacity of such additional screening filters is likely to depend on the throughput and the nozzle apertures , as well as the rate at which debris settle in tank 120 , as rinse water is preferably drawn from the top of tank 120 . accordingly , screen 140 may in fact be a series or collection of screens . in a more preferred aspect of the present invention , the bins 10 are rotated to and from the inverted position in the washing station by a plurality of l - shaped pivoting arms 500 . a non - limiting example of the use of such pivoting arms 500 with a conveyor system is illustrated in the plan view of fig5 , in which the central portion 180 provides the washing station 110 described above . however , bins 10 are delivered to conveyor 180 by an entry conveyor 180 ′ and removed from conveyor 180 after washing on the exit conveyor 5180 ′. while this embodiment shows the combination of conveyers 18 ′, 180 and 5180 ′ deployed in a u - shape , the l - shaped pivoting arms , which are described in further detail below , can be used with the central conveyor portion 180 only , provided the bins 10 are at least turned on their side when delivered thereto for washing . each l shaped pivoting arm 500 ( also designated as 510 , 520 and 530 in the alternative embodiments that follow ) has a vertical support section 501 and a horizontal support section 502 attached thereto substantially at a right or 90 degree angle , with an axle 503 or similar rotary means provided at the junction of these supports sections . it should be appreciated that the terms horizontal and vertical are relative , as they refer to the orientation of the orthogonally disposed arms in a nominal reference rotation angle of axle 503 . thus , as the pivot arm rotates about axle 503 to rotate the bin 10 by 90 degrees each arm will alternate between the vertical to horizontal orientations . a shown in fig5 , the bins 10 while optionally received in the upright position , are first flipped 90 degrees ( bin 10 ′) on loading to the entrance conveyor 180 ′, and then to an inverted position ( bin 10 ″) before entry to the washing station 110 in the process of being transferred from the entry conveyer 180 ′ to the central conveyor 180 . likewise , after washing , the inverted bins 10 ″ are flipped 180 degrees to the upright position ( bin 10 ′″) on removal from the washing station on the central conveyor portion 180 as they are transported to the exit conveyor 5180 ″. alternatively , the bins 10 may be flipped 180 directly on the central conveyor 180 housing the washing station 110 . it should be appreciated that an accumulating track can be deployed on placed of conveyor 5180 ′, in which the track has free spinning rollers to support the bins , and the entrance of a new clean bin on the track then urges the other bins forward . it is particularly preferable that the 180 degree flip of each bin 10 before and after washing is provided by the cooperative action of pair of l - shaped pivoting arms 510 and 520 , each of which rotates the bins 10 by 90 degrees . a particularly preferred aspect of such conveyance is illustrated in fig6 and 9 - 15 . it should first be noted in fig6 that the first l - shaped 510 is position to receive the bin 10 via the conveyor tracks 181 and 182 . hence , the vertical support section 501 or horizontal support section 502 , while optionally solid or an open , is preferably pronged in a fork like manner to fit within the conveyer 180 , between tracks 181 and 182 . further , on rotation of l - shaped pivoting arm 510 counter clockwise 90 degrees about axle 503 , the present vertical support section 501 is configured to fit in nested engagement within the horizontal support section 522 of the second l - shaped pivoting arms 520 . this orientation of l - shaped pivoting arm 520 after rotation is illustrated in fig8 a and 8b . thus , without further need for lateral conveyance of the bin , the further rotation of the second l - shaped pivoting arm 520 by 90 degrees in the counter clockwise direction ( about axle 523 ) will complete the inversion of the bin 10 , disposing in the vertical support section 521 , which would then be substantially horizontally oriented . in more preferred embodiments illustrated in fig6 - 14 , the l - shaped pivot arm 520 , has a vertical or horizontal support portion that includes a means to convey the bin laterally after rotation of 90 degrees . thus , as shown in fig7 a and 7b , vertical support section 521 includes a pair of right 582 and left 581 roller tracks , which are support by a frame 523 . in the particular embodiment of fig8 - 13 , the conveyance is accomplished by a pneumatically actuated push rod 526 with initiates the rolling movement of the bin over a series of free spinning rollers 581 and 582 . a frame 524 also supports an actuator rod 525 that propels a push bar 526 that is coupled thereto . the actuator rod 525 drives the push bar 526 in the direction of arrow 527 , so that when it is finally disposed at the phantom position 526 ′ it will urge the bin 10 to roll on the roller tracks 581 / 582 . as the vertical support section 521 preferably has as a support portion 522 consisting of the free spinning roller tracks , 581 and 582 , is preferably pointed slightly downward so that the movement is assisted by gravity . the stroke of the push rod is about the width of the bin 10 . further lateral conveyance of the bin 10 after this 90 degree rotation can be either in the direction of the rotation axis associated with the l - shaped pivoting arm , or transverse . conveyance in the direction of the rotation axis is appropriate where the central conveyor portion 180 and the entrance 180 ′ or exit conveyors 5180 ′ are disposed at right angle as shown in fig5 . the contrary of the l - shaped pivoting arm 530 using roller 580 to conveyor the bin transverse to the rotation axle 530 of the l - shaped pivoting arm is shown in fig1 a and 15b . the sequence of the collaborative movement of l - shaped pivoting arm 510 and l - shaped pivoting arm 520 is depicted in more detail in fig9 a - 14a , in which the bin is omitted for clarity . however , the bin orientation and position in illustrated in the inset labeled fig9 b - 14b on the correspondingly numbered figure . thus , fig9 a corresponds to the orientation of the l - shaped pivoting arms 510 and 520 shown in fig7 , but in a perspective view . in fig1 , 510 is rotated 90 degrees counter clockwise to position bin 10 onto horizontal support section 521 of l - shaped pivoting arm 520 . fig1 a shows the process of l - shaped pivoting arm 520 rotating 90 degrees counter - clockwise , in which it has rotated about 45 degrees . fig1 the completion of the 90 degree rotation of l - shaped pivoting arm 520 . fig1 shows the process of l - shaped pivoting arm 520 returning to the position in fig ., in which it has rotated about 45 of 90 degrees clockwise . fig1 shows the process of l - shaped pivoting arm 510 returning to the position in fig ., in which it has rotated about 45 of 90 degrees clockwise . fig1 a and 15b illustrate an alternative embodiment in which either single or multiple roller tracks or conveyor 580 is disposed vertical support surface 531 on l - shaped pivoting arm 530 to urge bin 10 onto the accumulator track 5180 ′ that is oriented to convey sequential bins in the same direction as they are transported on conveyor system 180 having washing station 110 . it should be appreciated that alternative conveyance means to the push rod 526 and roller combination 581 / 582 of fig7 - 15 is powered belt , linked plates , chain drive ( s ) and the like . while the invention has been described in connection with a preferred embodiment , it is not intended to limit the scope of the invention to the particular form set forth , but on the contrary , it is intended to cover such alternatives , modifications , and equivalents as may be within the spirit and scope of the invention as defined by the appended claims .
