  • This invention relates to an apparatus for processing items.
  • the invention is suited for use in produce items such as abalone, mussels, scallops, carrots, potatoes and in particular oysters, and it will be convenient to hereinafter describe the invention in relation to this particular application. It should be appreciated however that the invention has wider application.
  • the supply of oysters, and indeed any of the previously identified product items, to market generally involves some type of processing to determine whether they satisfy market requirements.
  • the processing may include counting, weighing and/or measuring the length of each individual item. These processing steps generally require a preprocessing step of separating the individual item from a plurality of the items.
  • Oysters are tested in order to determine whether they satisfy certain market requirements. Each oyster is tested for weight and/or the length of its outer shell.
  • Another prior arrangement includes manually loading a carousal with oysters which are subsequently weighed by a machine. Again the process involved is labour intensive and does not test the length of the oysters.
  • a processing apparatus for automatically processing a plurality of items according to a predetermined standard including: separator means which receives the plurality of items and separates individual items from the plurality of items; and measuring means which measures each separated individual item to determine whether it satisfies the predetermined standard.
  • the separator means includes a funnelling element which receives the plurality of items at an upstream end, and funnels the items towards a downstream end of the funnelling element to discharge therefrom in substantially a single file. It is further preferred that the funnelling element rotates about its longitudinal axis to facilitate the funnelling process. It is further preferred that the speed at which the funnelling element rotates is adjustable to adjust the speed of the funnelling process. It is further preferred that the upstream end of the funnel element is raised relative to the downstream end of the funnel element to facilitate the funnelling process. It is further preferred that the funnelling element is angled relative to a horizontal plane such that the upstream end is raised relative to the downstream end, whereby the angle of the funnelling element relative to the horizontal plane is adjustable.
  • the funnelling element includes a hollow frusto conical portion having a relatively wide opening at one end thereof, and a relatively narrow opening at an opposite end thereof, wherein the wide opening is positioned at the upstream end of the funnelling element.

  • the funnelling element is supplied with the items at a controllable rate by a supplying means, the supplying means includes a supply conveyor being in communication with a store of the items, the supplying means also includes a batch weigher which is supplied with the items by the supply conveyor and temporarily accommodates the items whilst they are being supplied to the funnelling element, the batch weigher weighs the amount of temporarily accommodated items and where this weight exceeds a predetermined weight the supply conveyor is stopped until the weight of the items is less than the predetermined weight, at which point the supply conveyor is started again. It is further preferred that the predetermined weight is adjustable to optimise the rate of supply of the items to the funnelling element.
  • the separator means includes a queuing means which receives the items from the funnelling element and supplies the items to a spacing and orienting conveyor at a constant rate.
  • the queuing means includes a pair of substantially parallel cylinders the external surfaces of which define a passageway along which the items are progress, the cylinders are adjustably angled relative to a horizontal plane to facilitate the progression of items along the cylinders.

It is further preferred that at least one of the cylinders includes a raised scroll for controlling the progression of the items along the cylinders, whereby the scroll extends from a mid portion of the cylinders to a discharge end of the cylinders at which end the items are supplied to the spacing and orienting conveyor. It is further preferred that the pitch of the scroll increases along the length of the cylinder. It is further preferred that the pitch of the scroll causes the items to be supplied to the spacing and orienting conveyor in a spaced manner. It is further preferred that the raised scroll has a rectangular cross section.
  • the spacing and orienting conveyor functions to space or further space each item, and orient the longitudinal axis of each item with its direction of travel as the items are progressed along the spacing and orienting conveyor. It is further preferred that the spacing and orienting conveyor includes a pair of sloping surfaces which have an included angle of between 60° to 120° for facilitating orientation of the longitudinal axis of each item with its direction of travel. It is further preferred that the spacing and orienting conveyor includes vibrating means to further facilitate orientation of the longitudinal axis of each item with the direction of travel.

  • the spacing and orienting conveyor includes a first portion and a second portion whereby the speed of the first portion is slower that the speed of the second portion so as to space the items as they progress from the first to second portions.
  • the spacing and orienting conveyor supplies the items to the measuring means in a spaced and longitudinally oriented manner, wherein the measuring means includes a length measuring means for measuring the longitudinal dimension of each item. It is further preferred that the length measuring means includes a photocell, ultraviolet or laser beam emitter which measures the length of each item. It is further preferred that means for storing the length measurement for each item is included, comparing that with a predetermined standard length and identifying the item as either under length, over length or on length.
  • the measuring means includes a selector means which receives the items after they have been processed by the length measuring means, the selector means functions to separate the items into under length, over length and on length. It is further preferred that the selector means includes at least two movable blades for deflecting those items identified as under length or over length. It is further preferred that the selector means includes a selector conveyor for progressing the items through the selector means, whereby the at least two blades deflect those items identified as under length and over length in a direction substantially transverse to the direction in which the items are progressed by the selector conveyor.
  • those items identified as on length are progressed by the selector conveyor to a weight measuring means, which weight measuring means measures the weight of each item. It is further preferred that means for storing the weight measurement for each item, comparing that with a predetermined standard weight and identifying each item as either on weight or not on weight.

  • separator means 2 supplying measuring means 3.
  • a plurality of oysters are provided to the separator means 2 at a funnelling element 4 which supplies single and possibly separated oysters to a queuing means 5, which in turn supplies oysters to a spacing conveyor 6 which supplies each oyster in a spaced manner to the measuring means 3.
  • Each oyster is supplied to a length measuring means 7 of the measuring means 3 to measure the length of the oyster, and provided the oyster satisfies the market requirements for length it is supplied to a weight measuring means 8 via a selector means 9.
  • the funnelling element 4 is supplied with the plurality of oysters by an elevator conveyor 10 raising the plurality of oysters in clumps from a store of oysters located at a position below the funnelling element 4, however this is clearly not essential. Any suitable means, such as a declining chute leading from a store at a position above the funnelling element 4, may alternatively be utilised to supply the funnelling element 4 with oysters.
  • a batch weigher 13 which functions to regulate the supply of oysters from the elevator conveyor 10 to the funnelling element 4 so that the rate of supply does not exceed the rate at which the oysters are processed by the funnelling element 4.
  • the batch weigher 13 illustrated includes a temporary holder 36 balanced by a counter-weight 37 and pivotally connected thereto via a pivot 38. Where the rate of supply of oysters exceeds the rate at which the oysters are processed by the funnelling element 4 the overflow of oysters will collect in the temporary holder 36. Where the weight of the overflow of oysters in the temporary holder 36 exceeds the counter-balanced weight 37 the temporary holder 36 will drop to engage a switch 39.
  • the switch 39 is in communication with the power supply to the elevator conveyor 10 so as to shut off the power to the elevator conveyor 10.
  • This allows the funnelling element 4 to continue processing the overflow of oysters which reduces the weight in the temporary holder 36 and enable the counter-balanced weight 37 to overcome the weight of the overflow of oysters, which disengages the temporary holder 36 from the switch 39 and returns the power to the elevator conveyor 10.
  • Other means for controlling the supply of oysters to the funnelling element 4 are clearly possible.
  • the funnelling element 4 illustrated in figures 3a and 3b functions to allow each oyster to exit individually and possibly separated from adjacent oysters.
  • the preferred embodiment shown in figure 3 has the funnelling element 4 including a flared entry portion 11 spaced from an exit portion 12 providing a guide path for the oysters to the queuing means 5.
  • the funnelling element 4 as illustrated is adjustably angled to the horizontal by approximately between 5 to 20 degrees, and preferably 10 degrees, to use the force of gravity to assist with the processing of oysters through the funnelling element 4. It should be appreciated that adjustment of the angle of the funnelling element 4 will control at least in part the speed of processing of the oysters through the funnelling element 4.
  • the processing of the oysters may also be assisted by rotation of the funnelling element 4 about its longitudinal axis. The speed of rotation may be adjusted to further control the speed of processing of the oysters through the funnelling element 4.
  • Rotation of the funnelling element 4 facilitates alignment of the individual oysters from the clump of oysters, which in combination with the size of the exit portion 12 relative to the size of the oyster allows each oyster to exit individually and possibly separated from adjacent oysters.
  • the exit portion 12 is located relative to the queuing means 5 to supply individual oysters to one end of the queuing means 5.
  • the queuing means 5 shown includes a pair of cylinders 14, 15 which are arranged in the processing apparatus 1 side by side such that their longitudinal axes are substantially parallel. It is preferred that the outer rotating surfaces be positioned to retain the oysters whilst they are in the queue. To achieve this regard may be had for the diameter of the cylinders 14, 15 and their relative positions.
  • the cylinders 14, 15 may be positioned such that their outer surfaces are almost touching or spaced up to 15mm. It should be appreciated that this spacing may change for shellfish and other product items of a different size and accordingly the cylinders 14, 15 are preferably adjustable to accommodate the different sizes.
  • the cylinders 14, 15 rotate in opposite directions and receive the individual oysters on their outer rotating surfaces. Again the speed of rotation of the cylinders 14, 15 assists in the control of the speed at which the oysters progress along the queuing means 5.
  • the cylinders 14, 15 are angled relative to the horizontal in a manner similar to the funnelling element 4, to allow the force of gravity to further assist in the progression of the oysters along the cylinders 14,15. Both the speed of rotation of the cylinders 14, 15 and the angle the cylinders 14,15 relative to the horizontal may be adjustable to control the progression of the oysters along the cylinders 14,15. Again a lubricant, preferably water, is applied to the cylinders 14, 15 to reduce the friction between the oysters and the cylinders 14, 15.
  • each of the cylinders 14, 15 include a raised scroll 36 for facilitating progression of the oysters along the queuing means.
  • the scroll 36 illustrated commences approximately mid way along the cylinders 14, 15, however it may commence at a different position.
  • the pitch of the scroll 36 as illustrated increases as it progresses along the cylinders so as to space the oysters, however this is not essential. For example the pitch may remain constant.
  • the cross-sectional shape of the raised scroll 36 may be in any appropriate form however a rectangular cross sectional shape has been found most suitable. Other shapes including square and semi-circular have also been found suitable.
  • the queued oysters are supplied to the spacing and orienting conveyor 6 as illustrated in figure 3 in a single line.
  • the oysters will be supplied spaced from each other when the scroll 36 is used or in contact with each other if no scroll 36 is used.

  • the embodiment of the spacing and orienting conveyor 6 illustrated in figure 4a includes a support rail 17 for supporting a plurality of bobbin carriers 18 along its length. As illustrated in figure 5 each bobbin carrier 18 includes arms 19 with each arm 19 accommodating a bobbin 20 and providing an axis of rotation for the bobbin 20.
  • Each bobbin 20 on each bobbin carrier 18 is connected to a corresponding bobbin 20 on an adjacent bobbin carrier 18 by a plurality of flexible bands which have been removed for clarity. It is preferred that the bands be formed from a elastomer, such as urethane, with each band being tensioned by moving the bobbin carriers 18 along the support rod 17, but this is not essential.
  • the bands connected to each of two adjacent bobbins 20, as shown in figure 4a, are sufficiently close to one another to effectively form a supporting surface for each oyster received from the queuing means 5.

  • the oyster supporting surface associated with one of the bobbins 20 is angled at approximately 90 degrees relative to the oyster supporting surface associated with the other bobbin 20.
  • other angles may also be appropriate, with included angles of between 60 to 120 having been found suitable for receiving oysters of various sizes.

  • each bobbin 20 illustrated is composed of large diameter sections and small diameter sections arranged in alternating fashion along a major portion of the length of the bobbin 20.
  • the successive increments of speed are achieved in the example illustrated by connecting the large diameter of the bobbins 20 at the receiving end 16 with the small diameters of adjacent bobbins 20, and repeating this connection through the length of the spacing conveyor 6.
  • the first and final bobbins 20 of the spacing conveyor 6 may alternatively be of constant large and small diameters respectively and still allow the spacing conveyor 6 to function. Others means for increasing the speed of the oysters through the first portion 21 length of the spacing conveyor are possible.
  • a second portion 34 is designed to give the constant speed required for accurate measurement and also to settle movement of the oysters after the agitation of the previous stage.
  • the constant speed is maintained by attaching for the eurthane bands to bobbins grooves of the same diameter.
  • one of the bobbin pairs in this portion has the alternating diameter grooves of the first section in order to create a perturbation within the constant speed section to complete the oriention of those the oysters which may not have been fully orientated transiting the first portion 21.
  • FIG 4b there is illustrated an alternative form of the spacing and orienting conveyor 6.
  • the illustration shows the supporting surfaces defined a plurality of belts 37 extending around bobbins 20.

  • Figure 4b also illustrates the spacing and orienting conveyor 6 having a first portion 41 and a second portion 42.
  • the first portion is to progress the oysters at a slower rate that the second portion so as to space or further space the oysters as they progress along the spacing and orienting conveyor.
