A Fruit Packaging Tray, Apparatus and Process

Field of the Invention

This invention relates to improvements in respect of a tray, apparatus and processes for packaging items, such as packaging fruit items, and such as packaging fruit for transport.

Background of the Invention

Conventionally, trays are loaded in packaging lines by operators depositing fruit in trays which have pockets formed therein. The pockets typically have a surface which cooperates with the shape of fruit to be loaded therein so that the fruit are bedded in the pockets and so that pressure from the tray is spread over a cooperating surface of the fruit. Loading the trays typically requires the operator to orient the fruit to align with the shaped pockets.

There is often a disparity between the rate at which given operators can align and deposit fruit in pockets, which can make control of packaging lines challenging.

There can be a challenge in staffing packaging lines with operators who can load trays at an economic rate.

Other challenges arise in some trays not being completely loaded in time.

For enhanced storage of some types of fruit require a moisture barrier which is typically made from a moisture barrier film wrapped around the fruit.

Conventionally this requires an operator to load the film into a tray prior to loading the fruit and then wrap the film around the fruit in a way such that moisture ingress and egress is controlled.

This present a challenge in controlling the quality of the fruit wrapping and do this at an economic rate.

In view of the challenges above it would be of advantage to have an automated means of wrapping fruit that has been placed in trays.

In view of the challenges above it would be of advantage to have a tray which facilitates alignment of fruit with a pocket which has a surface which cooperates with the shape of fruit.

In view of the challenges above it would be of advantage to have a tray loading apparatus which aligns fruit with a pocket which has a surface which cooperates with the shape of fruit.

In view of the challenges above it would be of advantage to have a tray loading process which aligns fruit with a pocket which has a surface which cooperates with the shape of fruit.

Further aspects of the invention will become apparent from the following description of the invention which is given by way of example only of particular embodiments.

Best modes for carrying out the invention

Figure 1 shows a perspective view of a packaging tray 1 according to an

embodiment of the invention. The tray 1 has a bed, or pocket, 2 to receive an item to be packaged. In this particular embodiment the tray 1 has multiple pockets 2. The tray 1 of this embodiment is suitable for being arranged in a stack (not shown). By action of the tray bedding the items in pockets 2 the items are held in orientations best able to spread pressure and minimise any damage to the items that may be caused if force is applied to the tray or items by trays above.

The tray 1 of Figure 1 is adapted to receive fruit, and kiwi fruit in particular.

Figure 2 shows an example of a kiwifruit 3.

Figure 3 shows a cross-section of an example kiwifruit in a longitudinal axis 4 (C-

C).

Figure 4 shows a cross-section of another example kiwifruit in a transverse axis 5 (D-D).

Figure 5 shows a longitudinal cross-section 4 of a shape characteristic of a population of kiwifruit.

Figure 6 shows a transverse cross-section 5 of a shape characteristic of a

population of kiwifruit.

The cross-sections 4 and 5 might be representative of cross-sections of a shape characteristic determined from measurements of a representative sample of a population of kiwifruit. The population sampled may be a given grade or a given variety of item, such as a variety of kiwifruit that are to be packaged together using the tray 1. The reader will recognise these measurements as characterising the shape of the items or population of items. Suitable characterisations will be apparent to the reader. In one example characterisation the shape characteristic may be defined by the medians of given measurements made on the sample of the population. In other examples, the characterisation may be defined by means and given numbers of standard deviations of measurements made on the sample of the population.

The shape characteristic illustrated by Figures 5 and 6 may have an elongate cross- section 8 in the longitudinal axis 6 and another elongate cross-section 9 in the transverse axis 7, perpendicular to the longitudinal axis. The shape characteristic illustrated here may, more specifically, have a longitudinal cross-section which may be approximated by three ellipses transposed by overlapping. The shape

characteristic illustrated here may also have a transverse cross-section which is approximated by a single ellipse. The reader will appreciate that for some populations the shape characteristic may have an elongate longitudinal cross- section but a circular, or approximately circular, transverse cross-section.

Figure 7 shows a top view of the tray 1 of Figure 1. As shown the tray 1 has overlapping rows 10 and 11, for example, of beds 2. The arrangement of

overlapping rows 6 and 7 maximises packing density of items and also lateral stability of a stack or filled trays.

Figure 8 shows a close-up plan view of a pocket portion of the tray 1 of Figure 1 and 7. Figure 8 shows a bed defined by a bedding surface 12 covering a bedding region 13 which has a profile shape complementary to the shape characteristic of the item 3 so the item is able to bed into the tray 1. In this example the shape of the bedding surface is complementary to the cross-section 6 and also the cross- section 7 of the shape characteristic of the item 3. The bedding surface is concave upwards, as shown on the page, in the form which items are deposited on the tray and received by beds 2. Figure 8 also shows a settling surface 14. The settling surface of this embodiment has a profile which extends upwards and away from the bedding surface 12 to provide a settling region 15 adjacent to the bedding region 13.

Figure 8 also shows a settling region 16 at an end of the bedding region 13. Also shown in Figure 8 is a separating surface 17 which separates adjacent beds 2.

The settling region 15 provides space for an item to move around if the tray 1 is agitated. For example, an item deposited on the tray 1 with the item orientated with the longitudinal axis 6 not aligned with the longitudinal axis 15 of the bedding region 13 will not sit in the bedding region 13 with pressure spread over the surface of the item by the bedding surface 12. If the tray is jiggled or vibrated to agitate the item relative to the tray 1, the item 3 will move laterally relative to the tray 1 and bedding region and partially into and out of the settling region 15. Ongoing agitation will cause the item to rest in the bedding region 13 with the centre of gravity of the item 3 as low as possible. Because of the complementary shape of the bedding surface 12 and the cross-sections of the item 3, the orientation of the item with the lowest centre of gravity will correspond to an orientation with pressure spread and items located suitably for stacking. This is, the items are received in alignment with the beds of complementary shape by movement laterally to the tray or bed under agitation where the movement is allowed by the space provided by the settling region and where the movement would otherwise be constrained by the complementary shape of the bedding surface 12 and the shape characteristic of the item. In will be apparent to the reader that profile of the settling surface 14 illustrated acts to direct an agitated item towards the bedding region. For example, the substantially straight, upward and outward directed profile may direct an item upwards and towards the bed 13.

Figure 10 shows a cut-away section of the tray of Figure 1 along the section A-A. Figure 11 shows a cut-away section of the tray of Figure 1 along the section B-B.

Figure 12 shows a close-up of the cross-section of Figure 10 illustrating the shape of the tray 1 with a lateral cross-section 9 of the shape characteristic of items 3. As illustrated, the bedding surface 12 defines a shape has a profile complementary to the cross-section 9 in a bedding region 13a. Figure 12 shows the settling surface extending upwards and outwards from the curve of the bedding surface 12 to define a space 16 in the settling region 15a.

Figure 13 shows a close-up of the cross-section of Figure 10 illustrating the cross- section shape of the tray along the B-B of Figure 10. As illustrated, the bedding surface 12 defines a shape which has a profile complementary in a bedding region 13b to the lateral cross-section 8 of the shape characteristic of the item 3. Figure 13 shows the settling surface 14b extending upwards and outwards from the curve of the bedding surface 12 to define a space 16b in the settling region 15b.

Figures 12 and 13 illustrate that in the embodiment shown the bedding surface 12 terminates and the settling surface 14 starts at a point below a centreline of the shape characteristic of an item received. This feature allows a separating region between pockets 2 to provide further space for lateral movement of an item.

Figure 14 shows an apparatus 20 for loading the trays. In this embodiment the trays 1 are those of Figure 1.

The apparatus 20 has a first loading station 21 and a second loading station (not shown). The first loading station 21 has a ramp 22 from which items to be packaged move down to be deposited on a tray 1 which is translated below the ramp 22. The ramp may be referred to as a depositor. The rate of translation of the tray may be controlled dependent on the number of items entering the ramp.

In this embodiment the first loading station 21 deposits an approximate number of items 3 that is a proportion of the number of beds in a tray 1. Some beds 2 are left empty after the first loading station 21 and these beds are filled at the second loading station. In this embodiment items are loaded manually by an operator at the second loading station. The portion of items loaded at the first station 21 of this embodiment is selected dependent of data carrying information on the rate of manual loading an operator is able to perform in given operational conditions.

Figure 15 shows a plan view of the apparatus 20 of Figure 14. As illustrated in Figure 14 the ramp 22 is loaded with items 3 by an oscillating distributor 23 so the items 3 are distributed over the width 24 of the apparatus 22, ramp 22 or tray 1. The ramp allows items 3 to slide or role towards a tray 1 while preserving the distribution of items over the width 24 provided by the oscillating distributor 23.

The oscillating distributor 23 is fed with a conveyor 25.

The loading station 21 as illustrated in Figure 14 has a set of rollers 26 extending laterally to a direction of movement of the trays 27. A tray 1 moving over the rollers 26 will be agitated causing the items received to be agitated to move laterally to the tray 1 and beds 2. This movement will typically involve parts of the items 3 moving in the settling regions 15 and the items settling in the bedding regions 13. The rollers may be referred to as a jiggle or vibration section of the apparatus 20. In some embodiments the rollers may be dimensions and spaced to cause the tray 1 to flex to agitate the items.

The apparatus 20 shown in Figure 14 has a conveyor 28 to move trays from the first loading station 21.

A process of loading trays according to an embodiment of the invention will now be described.

Trays 1 are translated below a depositor ramp 21 at a first loading station 22 to receive a number of items. In this example, the rate of translation of the tray is controlled dependent on the number of items entering the ramp to index the number of pockets moving under ramps to the number of items to be deposited.

The items 3 are fed to a ramp 21 by an oscillator which distributes the items over the width of the tray. The items 3 typically are not all aligned with the beds 2 at this time.

The items 3 had been fed to the oscillator by a conveyor 25.

The trays move over a set of rollers 26. In this particular example trays are flexible and the rollers are dimensioned and spaced to flex the trays and cause the deposited items 3 to be agitated and move laterally to the tray and the pockets to settle in the bedding regions 13 which have a shape that is complementary to the shape characteristic determined by characterising a sample of items of a population, grade or type to be packaged using the trays.

The trays 1 at this point in the process of this embodiment will typically have 80% of beds 2 filled by items, now bedded after settling by agitation.

At a second loading station (not shown) the remaining approximately 20% of beds which have not received items are filled. In this embodiment these beds are filled manually by an operator at the second loading station. In an alternative

embodiment the second station may be automated. In either embodiment the portion of pockets filled can be matched to a rate that a given operator,

characteristic operator or automated process to fill empty pockets, to align any items not aligned or to settle any unsettled items.

Figures 17 and 18 show an item packing apparatus 101 according to an

embodiment of the present invention. The apparatus provides boxes of wrapped trays filled with items. In this embodiment the items are fruit. In this specific embodiment the items are kiwifruit which have been graded. Figure 17 gives a plan schematic view with a direction of loading illustrated from left to right across the page.

The apparatus 101 has a marshalling station or stage 102, which receives items, transporting them to a consolidation stage 3. The consolidation stage 103 receives items and consolidates them in groups for quantity measurement. The

consolidation stage has a conveyor 106 to move the items. The quantity

measurement of items is performed with a camera 104 which feeds data to a controller or processor 105.

In this embodiment the processor 105 controls the camera 104. The conveyor 106 moves the items to a tray depositing device 107. In this embodiment the item depositing device is a ramp slide, or ramp, 108 which is filled with items by the conveyor 106 and allows the items to slide or roll downward in the direction of loading of the apparatus.

The apparatus 1 shown in figure 17 has a tray conveyor 109 which conveys a tray 110 under the ramp 108 in the loading direction. In this example the conveyor translates the tray. The tray conveyor 109 has a position and speed which is controllable. In this embodiment the tray conveyor 109 is controlled dependent on data provided by the processor 105 to allow the tray conveyor to be moved dependent on a quantity of items assessed at the consolidation stage 103. In this embodiment the tray conveyor indexes the movement of the tray 110 to a number of items calculated as likely to fall in an item-wide section of the tray. This is, tray 110 is controlled to index the number of pockets of a tray exposed to the ramp 108 to the number of items to be deposited on the tray 110. Alternative control regimes may be used in alternative embodiments.

The apparatus 101 as shown in figure 17 has a vibration table 111 over which the tray 110 and items deposited on the tray moves. Whilst on this table the tray is excited in x and y directions thus shaking or vibrating the items in the tray. In this embodiment the pockets are formed to have a shape complementary to a shape characteristic measured for a population or sample of population of the items. In this embodiment the population is a grade of fruit and the pockets have a surface which cooperates with a profile of a shape characteristic of the grade of the given fruit. In this embodiment also the pockets have a surface adjacent the cooperating surface which extends upwards from the cooperating surface at a tangent to provide a surface and space to allow items to move when jiggled to settle into the cooperating surface.

The apparatus 101 has a turning station 112 which turns trays by approximately 90 degrees and loads them onto a conveyor 114. In this embodiment the trays 110 are elongate having a length which is approximately the width of the ramp 108 and table 111. The turning station 112 turns the trays 110 to align the length with the direction of loading. The applicant has observed that elongate trays 110 can be fed though stages of the apparatus more stably if fed lengthwise.

A wrapping station 118 is also shown in figure 1. The wrapping station 118 is able to receive trays 110 with items settled in pockets (not shown) and wrap these with a sheet of wrapping material (not shown).

The wrapping station 118 shown in figure 1 has a central conveyor 119 which is able to convey the sheet of wrapping material with wrapped tray in the loading direction. The central conveyor has a set of vacuum apertures 120 connected to a vacuum system (not shown) to hold the sheet of wrapping material against the central conveyor 119. A first portion of the sheet of wrapping material is held against the conveyor 119 by the action of the vacuum apertures and ambient air pressure.

The wrapping station shown in figure 17 has a first lateral conveyor 115 also with vacuum apertures 116 to force the sheet of wrapping material against the first lateral conveyor. The lateral conveyor is displaced laterally to the central conveyor 119 so the wrapping sheet being forced against the first lateral conveyor allows the first lateral conveyor to hold the sheet of wrapping material out as a second portion or lateral flap to the first or central portion central of the wrapping sheet.

The wrapping station 118 shown in figure 1 shows a second lateral conveyor 117 with vacuum apertures 121 displaced laterally from the central conveyor 119 on an opposite side of the central conveyor 119. The second conveyor 117 with vacuum apertures is able to hold a second lateral flap of the wrapping sheet out from a central part of the sheet of wrapping material.

The first lateral conveyor 115, central conveyor 119 and second lateral conveyor 117 are controlled to be able to synchronously move to allow the three conveyors to convey a thin sheet of material, forced against the conveyors.

The wrapping station 118 shown in figure 17 has a severing device 122 which is able to sever the sheet of wrapping material from a roll 123 of wrapping material to control the length of the wrapping material for each tray 110.

The wrapping station 118 shown in figure 17 has a first wrapping bar 124 which is able to move from under an extended lateral flap of wrapping material and over the central conveyor 1. In this embodiment the wrapping bar extends parallel to the central conveyor 119 and moves about a central axis of the central conveyor 119. By this action the first wrapping bar 124 is able to lift a lateral flap of the sheet of wrapping material, held extended laterally by the first lateral conveyor 15, and is able to deposit the lateral flap over a tray 110 resting on the central conveyor. Similarly, a second wrapping bar 125 extending parallel to the central conveyor 119 is able to move about the central conveyor 119 from below a lateral flap of the sheet of wrapping material to deposit the lateral flap over a tray resting on a central part of the sheet of wrapping material forced onto the central conveyor.

By the action of first wrapping bar 124 and second wrapping bar 125 depositing the lateral flaps of the wrapping sheet over the tray the tray with items is wrapped.

The wrapping station 118 has an additional wrapping bar 126 which is

perpendicular to the travel of the tray. The wrapping bar 126 is able to move downwards between the wrapping station 118 and box loading station 127 as the wrapped tray transitions from wrapping station 114 to box loading station 127. This allows the leading edge of the wrapping material to be moved below the level of the leading edge of the tray 110. This means the leading edge of the wrapping material will be wrapped under the leading edge of the tray as it continues its movement between wrapping station 118 and box loading station 127.

The apparatus 1 shown in figure 17 also has box-loading station 127. In this embodiment the box-loading station 127 has a ramp slide 128 down which a wrapped tray can slide.

A box conveyor 129 is arranged to locate a box tray 130 under the loading station such that a leading edge, leading in the loading direction, wrapped tray exiting the loading station 127 enters a leading end of a tray box 130. In this embodiment a tray box is a rigid tray which is able to support the weight of a number of similar tray boxes loaded with items. In this embodiment also the tray box is formed of a template of cardboard folded into a tray-shaped box. The box conveyor 129 is controlled to convey the tray box 130 with motion of a tray 110 in the loading direction. This allows the tray 110, which is flexible, to exit the box-loading station 127 and sit into a tray cavity defined by the tray box 130.

A jet 131 is arranged to direct a jet of air at the back of the tray 110 as it completes its loading into rigid tray box 130 to tuck the trailing edge of the wrapping material into the tray box.

Figure 19 shows a process according to a preferred embodiment of the present invention for providing packaged, wrapped and boxed items.

At step Sl-1 a tray in which items have been loaded and settled is moved onto a leading edge of a sheet of wrap. In this particular embodiment the tray is moved down a ramp onto the leading edge of the wrap. The wrap extends laterally wider than the tray. The leading edge of the wrap extends along a central conveyor in a direction of travel of the arriving flexible tray.

At step Sl-2 the tray slides onto the sheet near the leading edge of the wrap. The tray and the sheet are conveyed together until the tray is sitting completely on the wrapping sheet. In this embodiment the tray does not move relative to the wrapping sheet. Once the leading edge of the tray has touched the sheet, they are conveyed together along the belt.

The sheet of wrap also extends laterally to the central conveyor to provide lateral flaps of material. The lateral flaps are retained in laterally extended configuration by first and second lateral conveyors.

The conveyors have vacuum apertures connected to a vacuum to retain the sheet of wrap against the conveyors.

At step Sl-3 the leading edge of the wrap and tray is conveyed in a direction the arriving tray was moving and additional wrap is loaded onto the conveyor as the leading edge of the sheet and leading edge of the tray are conveyed to feed a section of sheet of wrap after the leading edge and arrange wrap under the length of the tray.

At step Sl-4 a trailing edge of the sheet of wrap is severed from a leading edge of a sheet of wrap provided for a subsequently wrapped tray.

At step Sl-5 a first wrapping bar moves about the central conveyor to release a first lateral flap from a first lateral conveyor and deposit it over the flexible tray.

At step Sl-6 a second wrapping bar moves about the central conveyor to release a second lateral flap from a first lateral conveyor and deposit it over the flexible tray.

At step Sl-7 the wrapping bar 126 moves downwards between the wrapping station 118 and box loading station 127 as the wrapped tray transitions from wrapping station 114 to box loading station 127. This allows the leading edge of the wrapping material to be moved below the level of the leading edge of the tray 110. This means the leading edge of the wrapping material will be wrapped under the leading edge of the tray as it continues its movement between wrapping station 118 and box loading station.

At step Sl-8 the jet 131 directs a jet of air at the back of the tray 110 as it completes its loading into rigid tray box 130 to tuck the trailing edge of the wrapping material into the tray box.

At step Sl-9 the wrapped tray is conveyed to a leading edge of a tray box, which is conveyed in synch with the flexible tray to deposit the wrapped flexible tray in the tray box. In this embodiment the tray is conveyed to a ramp which it moves down to a leading edge of the box.

In the embodiment of figure 1 the processor generates item quantity data which carries information on the quantity of items consolidated. The controller is able to control the tray conveyor. The controller is able specifically to control the

movement of a tray on the conveyor by controlling the speed of the conveyor in the loading direction.

The pocket has a concave surface 32 which has a cross-section which is concave upwards as shown on the page and shaped to cooperate with the shape characteristic of a population of items. In this example the population of items is a grade of a given variety of kiwi fruit and the shape characteristic is found by measuring a sample of the population. The pocket also has a surface 34 which, as shown in cross-section, extends outwards from the centre 35 of the concave section 32 and upwards as shown on the page. The cross- section of the surface 34 is substantially straight.

The tray 30 tray is shown with the surface 32 facing upward to receive. The surface 32 is shown concave upwards.

The substantially straight surface 34 is shown extending upwards as it extends away from the concave surface 32.

The concave section 32 is shown substantially conforming to a convex profile of part 37 of a hemisphere 39 of a shape characteristic of a population of items. The population in this example is a population of fruit selected from a wider population by a grading process. The population and/or wider population in this example is a fruit of a selected variety of fruit.

In some embodiments the separating region 17 may be defined by the settling surface 14.

In some embodiments the separating region 17 may be integral with the settling region 15.

In some embodiments the shape of the bedding surface is conformal to a shape characteristic determined for items to be received.

As illustrated the bedding surface has an upwardly concave shape and the settling surface has an upwardly convex shape. In some embodiments the settling surface may be a surface adjacent to the bedding region which is upwardly convex.

In some embodiments the bedding surface defines shape with a positive second differential of height with respect to progression away from the centre settling surface, with width or length, and the settling surface defines shape with a negative differential for similar progression away from the bedding region.

In some embodiments of the process of loading trays the number of items deposited at the first loading station may be determined so that a proportion of less than 90% of beds are filled.

In alternative embodiments a number of items that matches the number of trays are deposited onto the tray and the tray is jiggled or vibrated at a first station for a time which is likely to align a defined proportion of that number so the defined portion is likely bedded in the beds of the tray. The tray is then moved to a second station where the remaining items are aligned by an operator.

In some alternative embodiments a tray loading process for loading trays

comprising multiple beds to receive the items when the items are aligned with the beds. In some embodiments a loading station deposits a number of items on a tray, and an agitator agitates the tray to apply agitation characterised to align a defined proportion of the number of items deposited to settle the proportion of the items in respective beds, and an operator aligns items not aligned by the agitator at an alignment station.

In some embodiments, agitation is characterised by applying agitation with differing time and/or differing amplitude and counting the number of aligned items. The characterisation may be performed for different trays.

In some embodiments the proportion may be approximately 80%.

In some embodiments the proportion may be between 60 and 99%.

In some embodiments the proportion may be between 70 and 90%.

In some embodiments the proportion may be set dependent on second-station-step data carrying information on a number of beds that can be filled or aligned by an operator having a characteristic rate of loading empty beds with items at the second station.

The second-step data may carry information adjusted for a rate of loading of trays.

In some embodiments there is a point of inflection between an upwardly concave surface of a pocket of a tray and a surface adjacent to that section.

In some embodiments the section adjacent is upwardly convex.

In further embodiments the fruit measuring apparatus includes a camera to detect when an area of the belt is full. This determines a volume of fruit based on how much white space on the belt is visible to the camera.

In further embodiments the measuring device includes an ultrasonic sensor in place of the camera.
