    A FLOWLINE SYSTEM AND A METHOD FOR PROCESSING FOOD PRODUCTS FIELD OF THE INVENTION
    The present invention relates to a flowline system and a method for processing food products.
    BACKGROUND OF THE INVENTION
    Typical flowline systems that are used in the food industry comprise a conveyor and multiple of processing stations arranged along the conveyor where food products are processed. The processed food products are commonly released from the processing stations onto an underlying take-away conveyor that may feed the processed food products into any type of subsequent food processing equipment where subsequent processing steps take place. As an example, if the food products are fish fillets, such food processing equipment may be an X-ray apparatus comprising a cutting device, such as a high pressure water jet cutter, for cutting the fish fillets automatically around e.g. the pin bones and even into portions. Other examples for such subsequent food processing equipment could be a freezer for freezing the processed food products, or a portioning device for cutting the processed food products into portions.
    Such a take-away conveyor reserves a fixed sloth length for the processed food, e.g. the fish fillets, typically such that it corresponds to at least the length of the largest fish so as to prevent the fish fillets from overlapping, which is obviously not acceptable when the takeaway conveyor is configured to act as an infeed conveyor for the food processing equipment. This however has the drawback that if the processed food products varies much in their length there will be an empty space between the processed food products, .e.g. the fish fillets, which affects the throughput of the processing at the food processing equipment.
    SUMMARY OF THE INVENTION
    On the above background it is an object of embodiments of the present invention to provide a flowline system that is suitable to be operated as an infeed conveyor for subsequent food processing equipment where the throughput may be increased.
    In general, the invention preferably seeks to mitigate, alleviate or eliminate one or more of the above mentioned disadvantages of the prior art singly or in any combination. In
    DK 2016 70998 A8 particular, it may be seen as an object of embodiments of the present invention to provide a flowline system and a method that solves the above mentioned problems, or other problems.
    To better address one or more of these concerns, in a first aspect of the invention a flowline system is provided for processing food products, comprising:
    • a feeding conveyor for conveying the food products to be processed, • a plurality of workstations arranged along the feeding conveyor, • a control unit, • a diverting means associated with each of the plurality of workstations for diverting food products from the feeding conveyor to the workstations, and • a takeaway conveyor assembly, wherein each workstation comprises a release mechanism configured to receive a food product after being processed and to transfer the processed food product onto the takeaway conveyor assembly, and where the control unit is adapted to allocate a slot length on the takeaway conveyor assembly in accordance to a length of the processed food product.
    Accordingly, the distance between adjacent processed food products received by the takeaway conveyor assembly will be reduced and preferably be minimized since now the slot length is adapted to the length of the individual processed food products, e.g. a 80cm long processed fish fillet will be given more slot length than a 50cm long processed fish fillet. This means that the throughput of one or more subsequent processing steps performed by another processing equipment, when the takeaway conveyor assembly is implemented as an infeed conveyor, will be increased. An example of such one or more subsequent processing steps is where the processed food product is e.g. transferred into a freezer apparatus, or to an automatic cutting and/or trimming machine, e.g. where the processed food product may be exposed by X-rays and where the resulting X-ray signals are processed and used as an operation parameter in operating a cutting tool, such as a high pressure water jet. Other subsequent processing steps could include cutting the processed food products on the takeaway conveyor assembly.
    The term length of the processed food product may according to the present invention be understood as the length along a longitudinal axis of the processed food product meaning that if the food product is a fish fillet, it is the length of the fish fillet, and if the food product is loin of a meat it is the length of the loin.
    DK 2016 70998 A8
    In one embodiment, the takeaway conveyor assembly comprises a receiving conveyor arranged below the plurality of workstations, and where the step of allocating the slot length in accordance to a length of the processed food product comprises allocating such a slot length on the receiving conveyor. In another embodiment, the takeaway conveyor assembly comprises a receiving conveyor arranged below the plurality of workstations and a buffer conveyor arranged downstream to the receiving conveyor in an end-to-end arrangement, where the control unit is configured to utilize the length of the processed food product in operating the speed of the receiving conveyor and/or the buffer conveyor such that the slot length on the buffer conveyor is in line with the length of the processed food product.
    In one embodiment, the release mechanism comprising a weighing unit configured to weigh the processed food product. In an embodiment, the weight of the processed food product is compared to a reference weights or weight distribution, and based thereon the length of the processed food product is obtained. Accordingly, a simple solution is provided for utilizing the weighing data in obtaining a length or length estimated of the processed food product. This may as an example be performed by performing a calibration measurements where a particular type of food product, e.g. cod fillets, are weighed and where the weight is linked to the length of the fish fillets. Thus, a weight vs. length distribution is obtained. This may also be a process where e.g. the first x number of food products are to start with assigned with a fixed sloth length, sufficiently large, and where the length of the food products (e.g. the cod fillets) are in the subsequent processing step determined and linked to the weight. The resulting distribution is then utilized in acquiring the weight or weight estimate of the processed food product. As an example, said automatic cutting and/or trimming machine may determine the length of the food products, and where after a sufficiently accurate distribution is obtained that fixed slot length “process” is replaced with a “dynamic process” where the slot length selection is based on the length or length estimates of the food products.
    In one embodiment, the release mechanism comprises side by side arranged carrying members having length at least equaling the length of the processed food product and configured to receive the food product such that a longitudinal axis of the food product is essentially parallel to a longitudinal axis of the carrying members, and where the control unit is further configured to operate the releasing of the processed food product by means of simultaneously opening the carrying members at their adjacent sides, causing the processed food product to fall there through while maintaining the initial shape on the carrying
    DK 2016 70998 A8 members. It is thus ensured that the processed food product will remain its initial shape on the release mechanism and thus be optimally located/positioned for the one or more processing step which may e.g. include cutting the food product into portions. In such instances, it is obviously important that the food product is lying smoothly on the takeaway conveyor assembly, instead of being wrinkled that would require a manual intervene to un-wrinkle and reposition it and thus prepare it for the at least one subsequent processing step.
    In one embodiment, the release mechanism comprises a reference line configured to indicate where one end of the processed food product is to be situated. In that way, it is ensured that the processed food product always has a fixed reference point before it is transferred to the takeaway conveyor assembly meaning that the assigned slot length will be optimized.
    In a second aspect, the present invention relates to a method of processing food products, comprising:
    • conveying, by a feeding conveyor, the food products to be processed, • diverting a food product from the feeding conveyor to a workstation selected from a plurality of workstations arranged along the feeding conveyor, wherein the method further comprises:
    • processing the food product at the workstation, • placing the processed food onto a release mechanism, and • allocating a slot length on a takeaway conveyor assembly in accordance to a length of the processed food product.
    In one embodiment, the method further comprises transferring the processed food product from the release mechanism onto a takeaway conveyor assembly such that the shape of the processed food product is preserved. In that way, it is ensured that the processed food product is optimally positioned a d preserved for the one or more subsequent processing steps.
    In one embodiment, the takeaway conveyor assembly comprises a receiving conveyor arranged below the plurality of workstations, and where the step of allocating the slot length in accordance to a length of the processed food product comprises allocating such a slot length on the receiving conveyor. This receiving conveyor may e.g. be positioned such that it's free end acts as an infeed for another food processing equipment which may comprise a conveyor arranged in an end-to-an-end arrangement with the receiving conveyor, and where
    DK 2016 70998 A8 the dynamic allocation of the slot length maximizes the infeed from the receiving conveyor and into the food processing equipment.
    In general the various aspects of the invention may be combined and coupled in any way possible within the scope of the invention. These and other aspects, features and/or advantages of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Embodiments of the invention will be described, by way of example only, with reference to the drawings, in which figure 1 and 2 depict a perspective view and a top view of an embodiment of a flowline system according to the present invention for processing food products, figures 3 to 5 depict one embodiment of a release mechanism to be used in relation to the flowline system shown in figure 1 and 2, and figure 6 and 7 depict graphically one way of implementing the invention.
    DESCRIPTION OF EMBODIMENTS
    Figures 1 and 2 depict a perspective view and a top view of an embodiment of a flowline system 100 according to the present invention for processing food products, e.g. fish fillets or any other type of food products.
    The flowline system 100 comprises a feeding conveyor 101 for conveying the food products to be processed in a direction as indicated by arrow 106 and a plurality of workstations 102a,b arranged along the feeding conveyor 101.
    Each of the plurality of workstations 102a.b comprises a diverting means or as shown here sweep arms 105a,b for diverting food products from the feeding conveyor 101 to the workstations, receiving areas 103a,b where the unprocessed food products are accumulated together, processing tables 104a,b where the food products are processed by an operator (not shown), and a release mechanism 109a,b configured to among other things to receive a food product after being processed.
    The flowline system 100 further comprises a control unit 107 that is among other things configured to operate the diverting means in diverting the food products from the feeding
    DK 2016 70998 A8 conveyor 101 to the workstations 102a,b. This may e.g. be based on which of the workstations lack food products to be processed, and which not.
    The flowline system 100 further comprises a takeaway conveyor assembly, which as shown in this embodiment comprises a receiving conveyor 108 arranged below the plurality of workstations 102a,b, where the receiving conveyor 108 is configured to receive processed food products from the release mechanism 109a,b.
    The control unit 107 is further configured to allocate a slot length on the receiving conveyor 108 in accordance to a length of the processed food product, where the receiving conveyor 108 conveys the received processed food products in a direction as indicated by arrow 116. This means that if e.g. the food products are fish fillets having variable length, e.g. from 40cm-80cm, the allocated slot length is allocated accordingly. As an example, a processed fish fillet of 40cm may be allocated a slot length of 40cm plus 5cm on the opposite sides, i.e. 50cm, and a processed fish fillet of 80cm may be allocated a slot length of 90cm. The term length shall preferably be understood as the length along the longitudinal axis of the processed food products.
    The release mechanism 109, which will be discussed in more details in relation to figures 3-5, comprises a weighing unit configured to weigh the processed food product. This weighing information may as an example be utilized to measure the yield of the processing, where the food products may be weight before the processing and after the processing at the release mechanism. Also, in a preferred embodiment, the weighing of the processed food product may be used as an input is estimating the length of the processed food product by e.g. means of comparing the weight with a reference distribution linking the weight of the processed food product to the length.
    Figures 3 to 5 shown the release mechanism 109 discussed in relation to figures 1 and 2, where figure 3 shows the release mechanism 109 comprising said weighing unit, and two side by side arranged carrying members 302, 303 having length at least equaling the length of the processed food product, i.e. at least equaling the length of the longest food product to be processed. One of the opposite sides of the release mechanism 109 may further be configured to act as a reference line, e.g. side 304, so as to ensure that the reference position of the processed food product is always the same. This may be crucial when allocating the slot length for the processed food products to ensure their initial position at the release mechanism 109 is always the same, e.g. if the processed food product is only two third of the length of the
    DK 2016 70998 A8 release mechanism 109 it must be positioned at the correct reference position, i.e. said reference line.
    The side by side arranged carrying members 302, 303 are connected to an opening and closing mechanism (not shown) that is operated by the control unit 107 for opening and closing the adjacent sides of the carrying members 302, 303, when the processed food product has been assigned a slot on the receiving conveyor 108.
    Figure 4 shows as an example where a processed food product 401 has been placed onto the release mechanism 109 with one end of it facing said reference line 304, and such that the longitudinal axis of the food product is substantially parallel to the longitudinal axis 402 of the release mechanism 109.
    Figure 5 depicts an example where, in response to a control signal issued by the control unit 107, the adjacent sides carrying members 302, 303 open downward simultaneously causing the processed food product to fall down and into the slot that has been assigned to this particular processed food product such that its length fits optimally into the slot.
    More importantly, due to the design of the release mechanism 109 it is ensured that when the processed food product drops into said assigned slot length is preserves the initial shape as shown in figure 4.
    Figure 6 and 7 depict graphically one way of implementing the invention, where e.g. the food product shown in figure 5 falls down towards the receiving conveyor 108 (see figure 1), and where the slot length l shown in figure 6 has been allocated for this particular processed food product 401, such that it fits in the most optimal way in the stream of processed food items 601, 602 as shown in figure 7.
    The processed, or pre-processed food products shown in figure 7 may be used an infeed stream of food products for a subsequent processing steps (e.g. freezing process), where due to the elimination of the space between adjacent food products the throughput may be increased.
    While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiments. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the
    DK 2016 70998 A8 disclosure, and the appended claims. In the claims, the word comprising does not exclude other elements or steps, and the indefinite article a or an does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
