Description

PRODUCE HANDLING DEVICE AND/OR METHOD

TECHNICAL FIELD

[001] Embodiments of the invention relate to a produce handling device and/or method, for example for handling fruit and vegetables. BACKGROUND

[002] Dedicated machinery/devices typically used nowadays for handling produce (i.e. fruit and vegetables), do so according to various qualities/criteria’s, such as external qualities (e.g. color, skin defects, etc.) and/or internal qualities (such as weight, hardness measurement, brix degrees, ripeness, damage of the pulp, etc.). Such machinery may sort and package produce while ensuring that quality features are safeguarded and/or that produce are packaged according to defined criteria.

[003] In such machinery, the handling of the produce may begin at an incoming section where the produce is received. From the receiving section, the produce may be conveyed onwards downstream towards a singulator that can include one or more conveyors. The singulator may then urge the produce onwards downstream towards additional section(s) that may exist in such handling device, such as sorting and packaging sections (etc.).

[004] The singulator may include one or more successive sections. A conveyor of a typical section forming and/or included in a singulator, may include two generally parallel extending endless belts arranged in a V configuration. The belts in each conveyor operate at different speeds in order to rotate/spin the produce in an attempt to order it in a substantial single row. All conveyors are arranged to have similar speeds at their belts. In certain cases, the singulator may include additional sections downstream of the V-belt section for ordering the produce in a row, such as a section including spaced rollers (or the like). [005] US8776986 described that produce, in their example fruit, does not move at the average speed of the two belts in the V-belt section, but rather at a speed somewhere in-between the speed of the two belts. Such a V-belt section of a singulator causes fruit to assume a single line, which is then transferred to a series spaced rollers that are driven by a conveyor around in a closed loop. The section including the spaced rollers, permits in their example also grading of the produce by rotating the produce as it goes past possible photographic and weighing zones that assist in later sorting of the produce.

SUMMARY [006] The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope.

[007] In an embodiment there is provided a produce handling device comprising at least one singulator section for urging produce downstream, the singulator section comprising a plurality of generally parallel extending conveyors, and the handling device being arranged to selectively alter speed of each conveyor of the singulator in an independent manner in relation to other conveyors of the singulator.

[008] In certain embodiments possibly combinable with others, there is also provided a handling device comprising several successive section some of which being a singulator type but not necessarily. A first section preferably being of a singulator type and all successive sections comprising each a plurality of generally parallel extending conveyors for urging produce downstream, and the device being arranged to selectively alter speeds of one or more conveyors in each section in order to reduce gaps detected between adjacent articles of produce in sensed conveyor(s).

[009] In certain embodiments possibly combinable with others, there is also provided a handling device comprising a singulator type section with a plurality of generally parallel extending conveyors each comprising a plurality of supports. The device further being arranged to include a spiral member for preferably ensuring that relative long articles of produce, such as avocados or the like, are suitably placed in between adjacent supports - by engaging portions of such produce to urge it to substantially not project beyond the supports.

[017] Attention is first drawn to Fig. 1 schematically illustrating an embodiment of a handling device 10 for produce. The handing device here seen includes possible first and second sections 12, 14 of a singulator. A singulator is generally adapted to receive produce from upstream, e.g. from a receiving section (not shown) and transfer the produce onwards downstream while urging the produce to assume a substantial single line. Produce according to various embodiments of the present invention may be fruit and/or vegetables.

[018] It is noted that in certain cases, embodiments of a handling device of the present invention may be defined including one singulator section 12, while the other successive illustrated section 14 may then be considered as an additional section of the handling device downstream to the singulator, such as a sorting section of the handling device (or the like).

[019] In embodiments where section 14 is a singulator section, it may be arranged to include supports e.g. for introducing further order in the line of produce communicated downstream. Such a singulator section 14 may include a series of spaced apart rollers that are driven by a conveyor around in a closed loop (or the like). Such rollers, in some cases may permit grading of the produce by rotating the produce as it goes past possible photographic zones (or the like). [020] In yet further embodiments where section 14 is a singulator section, it may be arranged to be generally similar to section 12 or any other conveyor type structure suitable for moving produce downstream.

[021] Singulator section 12 possibly includes several generally parallel and longitudinally extending conveyors 121. Each conveyor 121 may be adapted to transfer produce arriving in a relative un-ordered manner from upstream, in a more ordered manner downstream towards a receptive co-axial conveyor 141 of section 14. In certain embodiments, section 14 may accordingly be considered as an additional singulator section, while in other embodiments as an additional section of the handling device downstream to the singulator (such as a sorting section or the like).

[022] In accordance with certain embodiments, each conveyor 121 of the singulator section 12 includes a pair of first and second endless belts 131, 132. In each conveyor 121, the belts 131, 132 may be arranged (supported possibly via a frame 7) to form a V shaped formation in a cross section perpendicular to the conveyor’s longitudinal axis (see cross section AA at the left-hand side of the figure). Such V shape opens upwards so that produce can be supported therein as it is transferred downstream.

[023] Belts 131, 132 in each given conveyor are traditionally arranged to advance at different speeds SI, S2 in order to urge produce entering the singulator from upstream to form a substantial line as the produce advances downstream. In a non-binding example, a speed ratio Sr between adjacent belts in a conveyor may be about 30%, e.g. SI = 0.3 X S2, (or the like) in order to urge produce transferred downstream to substantially form a line. [024] During the lining up process along the singulator, gaps G may be formed within a given conveyor 121 between adjacent produce being urged downstream. Such gaps G if transferred, e.g. to section 14 and onwards downstream, may reduce the overall throughput of produce being transferred downstream by the handling device 10 per unit of time. [025] An aspect of the present invention may thus be aimed at mitigating the formation of such gaps G in the singulator section and/or elsewhere along the handling device. By that, a produce handling device employing various embodiments of the present invention may exhibit increased throughput of produce per unit of time. In one example, such reduction in the amount and/or size of gaps G may be addressed by altering the speeds of belts in conveyors of the singular.

[026] In an embodiment of the present invention, handling device 10 may be provided with a sensor 2 associated preferably with each conveyor 121 of singulator section 12. Such sensors 2 may be provided adjacent a downstream side of each conveyor 121. The sensors, possibly optical sensors, may be arranged to detect produce passing downstream along the conveyor, while e.g. lack in detection of produce may be indicative of a gap G formed between produce along the conveyor. [027] In an embodiment, the size and/or length of a detected gap G may be assessed according to the time span of e.g. lack in detection of produce passing by the sensor. It is noted that sensors according to various embodiments of the invention may be suited to directly detect presence of gaps G e.g. by transmitting back and forth a signal that when received indicates lack of produce i.e. a gap. Other means suitable for such purpose maybe equally applicable.

[028] Attention is additionally drawn to Fig. 2 schematically illustrating an embodiment of a singulator section 12 that includes ‘n’ generally parallel conveyors 121. Sensors 2 located at or adjacent a relative a downstream side of, possibly, each conveyor may be tuned for detecting gaps G formed along each conveyor. Upon detection of a gap G at a given conveyor, a controller (not shown) associate and/or in communication with the handling device, may apply an increase IN in speed to the belts 131, 132 of the conveyor where such Gap G was detected.

[029] Possibly, such increase IN may be applied while maintaining a speed ratio between the belts 131, 132 suitable for lining up the produce. Possibly such speed ratio may be the same speed ratio Sr that initially existed prior to increasing the speeds of the belts. [030] By way of an example, if the speed of belts 131, 132 in a certain conveyor 121(i) is initially SI, S2; applying an increase IN(i) in speed to the belts of a certain conveyor may result in the respective speeds of these belts now being equal to IN(i)xSl, IN(i)xS2. In some cases, the increase IN in speed that is applied to the initial speeds may not necessarily be similar for both belts 131, 132 of the conveyor being tweaked.

[031] Attention is additionally drawn to Fig. 3 schematically illustrating a singulator section 12 and a successive section 14 downstream possibly also of a singulator type (but not necessarily). Produce tagged ‘ to ‘9’ are shown located along sections 12, 14, where in this example a first gap Gi is shown formed between produce tagged ‘7’ and ‘8’; and a second gap G2 between produce tagged ‘5’ and ‘6’ .

[032] Both sections 12, 14 may initially be set to convey produce downstream at respective rates that avoid un-intentional damage to the produce as it transfers from the conveyor of section 12 to that of section 14. Possibly, to avoid such un intentional damage to produce, the rates of both conveyors may be set so that produce progresses at substantially the same rate along both sections.

[033] Upon progress of produce downstream, as the produce tagged ‘5’ transfers from section 12 to 14, sensor 2 may detect the presence of gap G2. A controller receiving such sensed data may then urge the belts 131, 132 of section 12 to increase their speeds by applying an increase IN to the speeds SI, S2 as exemplified above.

[034] Since the speed of the produce now urged downstream along section 12 is increased in relation to the respective speed of the produce being urged along section 14, gap G2 is adapted to shorten/shrink in length. Such increase in the speed of a conveyor of section 12 may persist until the produce tagged ‘6’ advances towards a position where it is about to transfer to section 14.

[035] Upon detection by sensor 2 of the arriving produce ‘6’ from upstream and hence the termination of gap G2, the controller may lower the speeds of the belts of section 12 (e.g. by ceasing to apply increase IN to their speeds). Consequently, the speed of produce along section 12 may slow back down towards its initial speed suitable for transferring produce to section 14 without incurring un-intentional damage to the produce. Upon detection of gap Gi the same sequence of events may re-occur in order to shrink the extension of gap Gi too - and by that increase the overall throughput per unit of time of produce being urged downstream.

[036] Attention is drawn to Fig. 4 exemplifying an embodiment of the present invention, including a singulator section 12a and a successive downstream section 12b possibly of a singulator type (but not necessarily). Downstream of section 12b in this example may be provided a successive section 14 possibly of a singulator type (but not necessarily).

[037] In an embodiment, so long as no substantial gaps are detected by sensors 2a and 2b, sections 12a, 12b and 14 may be tuned to convey produce downstream at substantially similar rates/speeds. In the provided example, when produce ‘5’ transfers from section 12b to 14 and upon detection by sensor 2b of gap G2, both sections 12a and 12b may increase their speeds in order to shrink, inter alia, gap G2. [038] Once produce ‘7’ transfers from section 12a to 12b and upon detection by sensor 2a of gap Gi, as long as the end of gap G2 has not yet been detected (and hence no produce is about to transfer from section 12b to 14) - section 12a may advance its speed in relation to section 12b and by that act to shrink gap Gi that precedes produce ‘8’ before this produce ‘8’ reaches section 12b.

[039] Thus by arranging a produce handling device, where control of respective speeds in a series of successive sections (here 12a, 12b) is provided - such handling device may be arranged to exhibit higher throughputs of produce per unit of time, by shrinking gaps detected between adjacent articles of produce, possibly to a larger extent.

[040] Attention is drawn to Fig. 5 exemplifying a handling device embodiment generally similar to that in Fig. 1 - but here being provided with storage zones 77 for storing produce to be selectively fed to conveyors 121 and/or 141. The storage zones 77 may be positioned in-between pairs of conveyors 121 and 141 for supplying upon demand produce to the conveyors 121 and/or 141 of such pair.

[041] Sensors (not shown) arranged along the conveyors 121 and/or 141 of section 12 and/or 14 may be arranged to detect gaps G formed between adjacent articles of produce in each given conveyor and activate sideways ejection of produce towards such gaps G in order to fill them. The double lined arrows illustrated at one of the sections 12 and 14, exemplify ejection of two articles of produce sideways into a passing gap G detected as present.

[042] The ejection of articles of produce from such storage zones 77 in order to fill gaps G may be facilitated via an array of apertures (not shown) located along a storage zone. Through such apertures, air pressure may for example be selectively applied in order to eject and/or urge articles of produce to fill detected gaps G. In alternative to air pressure, others means may be applied such as mechanical means (or the like) for selectively urging produce along a zone 77 sideways into a selected conveyor. It is noted that the solution exemplified in the embodiment shown in Fig. 5 may be applied in addition to other solutions disclosed herein, such as those for shrinking gaps G by altering conveyor(s) speed(s) or other solutions such as those discussed below.

[043] Attention is drawn to Fig. 6 exemplifying an embodiment of an ensuing singulator section 14. The upper part of this figures provides a side view of section 14 and the lower part of this figure provides a top view of section 14. The provided illustrations exemplify ordering of produce having a relative longitudinal shape (such as avocado or the like) as opposed to a more rounded shape existing in some varieties of produce (such as in apples or the like). [044] Singulator section 14 may be of a type including supports 99 for introducing further order in a line of produce being urged downstream. Typically, a produce located upon singulator 14 may find its resting point in a relative recessed region 55 located substantially in-between adjacent supports 99, in order to further ‘single’ out each produce from its adjacent produce as it is urged onwards downstream. In certain cases, singulator section 14 may be chosen to include a series of spaced apart rollers as its supports 99, which may be driven e.g. by a conveyor around in a closed loop.

[045] A handling device including such a singulator 14 may be arranged to include a spiral member 88, possibly in the form of a spiral brush. Spiral member 88 may be arranged to include a pitch Ps generally similar to a pitch Pr between adjacent supports 99 of singulator 14.

[046] Spiral member 88 may be arranged to rotate about a shaft 44 that is generally parallel to an axis X defining the direction of advancement of singulator section 14 downstream. The rate of rotation of spiral member 88 may be tuned to the rate of advancement of singulator 14 downstream - so that the spiral shape of member 88 may be suitably positioned to urge produce caught in-between rotating segments spiral member 88 and a cavity 55 of the singulator - to assume an “sideways” orientation where its longitudinal extension is biased to be generally perpendicular to axis X.

[047] Such appropriate sideways placement of produce having a longitudinal shape on singulator 14 - may increase reliability of measurements of the produce - e.g. by avoiding such produce from touching each other, an event that if occurs may harm accuracy of optical and/or weight measurements (or the like). [048] Attention is drawn to Fig. 7 illustrating possible appliance of spiral member also to singulator section 12. Such spiral 88 in this case may also be utilized for ordering line formation along section 12 and in certain cases the rate of rotation of spiral section may be adjusted to the rate/speed of the belts 131, 132 in the conveyors 121 as they are urged faster or slower as already detailed in former embodiments disclosed here.

[049] It is noted that in the various embodiment disclosed herein, in particular those involving tweaking of conveyor(s) speed(s), means may be provided upon a surface of a conveyor in contact with the produce to avoid it from sliding relative to a conveyor as it accelerates or decelerates. For example, the surface of a conveyor (e.g. belts 131, 132) may be roughened in order to increase friction coefficient with the produce. In addition, or in alternative, a material of the surface of the conveyors in contact with the produce may be chosen to increase grip and/or friction onto produce. [050] In addition it is noted that the various embodiments disclosed herein may be used also for retrofitting existing produce handling devices in order to improve their throughput per unit of time. For example, the electronics and/or electrical wiring of an existing handling device may be modified to permit selective control of the speed of each conveyor of a singulator of the device in an independent manner relative to its adjacent parallel extending conveyors.

[051] Such modification to an existing produce handling device may accordingly permit shrinking gaps in certain conveyors 121 where gaps may be detected, while leaving other conveyors (e.g. where such gaps are not momentarily detected) at their original speeds.
