Description

[0001] SYSTEM FOR TRANSFERRING A CARCASS PART FROM A FIRST TO A SECOND TRANSPORT LINE

[0002] The present invention relates to transferring of a product from a first to a second transport line, in particular from a first conveying system to a second conveying system. The invention can e.g. be applied in the field of foodstuff processing, e.g. meat processing, e.g. poultry processing. The product can e.g. be a carcass part.

[0003] In meat (e.g. poultry) processing, an animal is usually slaughtered and subjected to various processing steps. Said processing steps can e.g. include deskinning, deboning, eviscerating, and cutting the carcass part into different parts. In modern processing plants, most of these processing steps are automated. The carcass part is transferred from one processing station to the next processing station by conveying systems in the processing plant. Usually the carcass part is transferred from a first conveying system to a second conveying system at least once in the processing plant. This can e.g. be necessary because a subsequent processing step is performed at a different conveying speed, or it may be necessary to hold the carcass part in a different way, or some carcass parts are subjected to other processing steps than others. Transfer systems exists to perform such transfers. However, it has been found that these are not always satisfactory. For example, some conventional transfer systems do not provide a lot of flexibility and / or controllability. Some of the conventional transfer systems are also relatively complex and include many components that are subject to wear, failure, and / or high maintenance costs.

[0004] An object of the invention is to overcome or at least partially mitigate the disadvantages of the prior art, or at least provide an alternative.

[0005] According to a first aspect, this object is achieved with a transfer system for transferring a carcass part from a first transport line to a second transport line, the transfer system comprising:

[0006] • a transfer mechanism configured to be arranged in a plurality of transfer positions, wherein each transfer position comprises a first line receiving position and a second line ejection position, the transfer mechanism comprising:

[0007] • a plurality of transfer holders for holding a carcass part;

[0008] • a transfer conveyor configured to move the transfer holders between at least the first line receiving position and the second line ejection position;

[0009] • a first ejector, configured to eject the carcass part from a first line holder of the first transport line into one of the transfer holders, when said transfer holder is arranged in the first line receiving position;

[0010] • a second ejector, configured to eject the carcass part from the transfer holder into a second line holder of the second transport line, when said transfer holder is arranged in the second line ejection position;

[0011] • a transfer mechanism positioner configured arrange the transfer mechanism in the plurality of transfer positions, wherein the transfer mechanism positioner is configured to move at least the first and / or second ejector relative to the first transport line and the second transport line for changing the first line receiving position and / or the second line ejection position.

[0012] The invention relates in embodiments to a system for transferring a carcass part. The carcass part can e.g. be derived from a slaughtered animal. The carcass part can e.g. be a poultry carcass part (e.g. a chicken carcass part), a bovine carcass part, a porcine carcass part. The carcass part can e.g. be a complete carcass or a part of the complete carcass. The carcass part can e.g. comprise at least one or more legs of the carcass. The carcass part can e.g. be a back halve. The carcass part can e.g. be a front part.

[0013] The transfer system is configured to transfer the carcass part between two transport lines. A transport line generally comprises a conveyor system for transporting a plurality of carcass parts in a conveying path. The conveyor system can e.g. comprise a plurality of holders configured to hold the carcass part, wherein the conveyor system can be configured to transport the holders. For example, the conveyor system can be an overhead conveyor. For example, the holders can be shackles, e.g. configured to hold a slaughtered animal by its extremities, e.g. by the leg(s) orfoot / feet. Different ways of holding the carcass part are however also possible. It is also possible that the conveyor system comprises a conveying belt configured to support the carcass part and transport the carcass part. It is also possible that the conveyor systems comprises holders that are embodied as trays or containers configured to support the carcass part. The conveying path can e.g. include be linear or curved, e.g. in a carrousel. The conveying path can e.g. include one or more processing stations, wherein the carcass parts are processed. Such processing stations can e.g. include one or more of the following: a loading station for loading the carcass part in the conveyor system; an assessment station for assessing the carcass part, e.g. measuring, weighing, or analyzing at least one property of the carcass part; an incision station for making an incision in the carcass part; a cutting station for cutting the carcass part in at least two parts; a skinning station for removing a skin of the carcass part; a deboning station for removing a bone from the carcass part; an unloading station for removing the carcass part from the conveyor system; a packaging station for packaging the carcass part; a mincing station for turning the carcass part into minced meat; a minced meat processing station for turning a minced product into a further product such as a hamburger or chicken nugget.

[0014] The first and second transport line may be embodied as similar types of transport lines, e.g. both being overhead conveyors (although other types of conveyors are also possible, e.g. having cone-shaped holders), but optionally be different on some aspects. For example, the first and second transport line may be configured to hold the carcass part in a different way; and / or transport the carcass part at a different speed; and / or transport the carcass part in a different direction; and / or transport the carcass parts with a different distance between to subsequent holders (and thus the carcass parts); and / or transport the carcass parts at a different height. It may also be possible that the first and second transport line are produced by a different manufacturer. It may also be possible that one of the first and second transport line is configured to transport the carcass part in a circular conveying path (e.g. a carrousel machine), and the other in a linear conveying path or a different circular conveying path. The transfer system comprises a transfer mechanism. Generally speaking, the transfer system may be configured to obtain the carcass parts from the first transport line, and deliver the carcass parts to the second transport line.

[0015] The transfer system comprises a plurality of transfer holders. The transfer holders are configured to hold a carcass part. Optionally, the transfer holders are configured to hold the carcass part in the same manner as a first line holder of the first transport line and / or a second line holder of the second transport line. Optionally, the transfer holders are configured to hold the carcass part by the extremities, e.g. by the leg(s) and / or foot / feet. The number of transfer holders may depend on the application and the size of the transfer conveyor, but can e.g. include at least three transfer holders, e.g. at least five, e.g. at least ten. Different types of holders are known to the skilled person and can be selected or designed depending on the application.

[0016] A transfer conveyor moves the transfer holders between a plurality of positions. Said positions include at least a first line receiving position and a second line ejection position. In the first line receiving position, the transfer holder is configured to receive the carcass part from the first transport line. The system comprises a first ejector for this. The first ejector is configured to eject the carcass part from a first line holder of the first transport line, into the transfer holder. The system further comprises a second ejector. When the transfer holder is in the second line ejection position, the second ejector is configured to eject the carcass part out of the transfer holder and into a second line holder of the second transport line.

[0017] The transfer conveyor thus moves the transfers holders from the first line receiving position to the second line ejection position, and back to the first line receiving position to receive a new carcass part. Generally, the transfer conveyor moves the transfer holders (at least for a part of a transfer transport path) in a direction which is different from the conveying direction of the first transport line, and different from the conveying direction of the second transport line. It may be possible that the transfer conveyor moves the transfer holders linearly back and forth, but it may be particularly advantageous if the transfer conveyor is configured to move the transfer holders in a closed loop, e.g. a circular or elliptical conveying path. This allows to move the multiple transfer holders without them interfering with each other.

[0018] The first line receiving position and the second line ejection position depend on which transfer position the transfer mechanism is arranged in. A plurality of transfer positions are possible for the transfer mechanism. Said plurality can e.g. include at least two, e.g. at least three, e.g. at least five, e.g. at least ten. Each transfer position comprises a first line receiving position and a second line ejection position. Between different transfer positions, the first line receiving positions are mutually different, and / or the second line ejection positions are mutually different. Thus, the location relative to the first transport line where the carcass part is transferred from the first transport line to a transfer holder can be mutually different between the different transfer positions. The location relative to the second transport line where the carcass part is transferred from the transfer holder to the second transport line can be mutually different between the different transfer positions. The first and second ejector may be embodied similarly (at least in working principle) to each other, but this is not required. For example, the first and / or second ejector may comprise a push element configured to push the carcass part out of the first or second line holder, respectively. An ejector actuator may be configured to move the push element between a rest position and an ejection position for pushing the carcass part. Different types of ejectors are known to the skilled person and can be selected or designed depending on the application.

[0019] The system further comprises a transfer mechanism positioner. The transfer mechanism positioner can arrange the transfer mechanism in the plurality of transfer positions. Thus, the transfer mechanism positioner is configured to control in which transfer position the transfer mechanism is arranged. To achieve this, the transfer mechanism positioner can move at least a part of the transfer mechanism, i.e. at least the first ejector and / or the second ejector. Optionally, the transfer mechanism positioner can also move the transfer holders and the transfer conveyor, e.g. the transfer mechanism positioner is configured to move the transfer mechanism. Optionally, the transfer mechanism positioner is configured to move the respective components of the transfer mechanism that are being moved, simultaneously. The transfer mechanism positioner may e.g. comprise a (mechanical) drive system, e.g. comprising one or more motors or actuators.

[0020] The transfer mechanism (at least some components thereof including the first and / or second ejector) is moved relative to the first and second transport line between a plurality of transfer positions. The different transfer positions differ relative to each other in that the first line receiving positions are different and / or the second line ejections positions are different. Thus, depending on which transfer position the transfer mechanism is in, the carcass part is received in a different position and / or ejected in a different position. This has the advantage of providing flexibility in how the carcass part is transferred. For example, the first ejector can pick the carcass parts selectively out of the first transport line. The transfer holders can also function as a buffer.

[0021] In embodiments, the transfer mechanism positioner is configured to move the transfer conveyor simultaneously with the first and / or second ejector, relative to the relative to the first transport line and the second transport line. The transfer mechanism positioner is configured to move the transfer holders simultaneously with the transfer conveyor as well. Thus, the transfer mechanism positioner is configured to move the (complete) transfer mechanism simultaneously. This is thus a movement of the transfer conveyor as a whole, not the movement of the transfer conveyor moving the transfer holders. Of course, it may be possible that the transfer conveyor moves the transfer holders in the transfer conveying direction at the same time. For example, the transfer conveyor may be configured to move the transfer holders in a (closed loop) trajectory, and the movement of the transfer conveyor by the transfer mechanism positioner may be configured to change the position of said trajectory relative to the first transport line and the second transport line. For example, the transfer conveyor may comprise a transfer conveyor track, wherein the transfer mechanism positioner is configured to move the transfer conveyor track. For example, the movement of the transfer conveyor may be a translation of the transfer conveyor, e.g. in a direction parallel to the first and / or second transport line. In embodiments, the transfer conveyor is configured to transport the carcass part in a transfer path, wherein the transfer path comprises a first section parallel to the first transport line and a second section parallel to the second transport line, wherein the transfer mechanism positioner is configured to move the first ejector along the first section for changing the first line receiving position and / or to move the second ejector along the second section for changing the second line ejection position. When the first / second transport line is configured to move the carcass part in a linear direction, the first / second section may be linear. When the first / second transport line is configured to move the carcass part in a curved direction, the first / curved section may be curved.

[0022] In embodiments, the transfer system further comprises a control unit, wherein the control unit is configured to control the transfer mechanism positioner for controlling the position between said plurality of transfer positions. Optionally, the control unit is configured to receive a first line information input and / or a second line information input, and control the transfer mechanism positioner based on the first line information input and / or the second line information input. As such, the control unit can control where and when the carcass parts are ejected from the first transport line and / or arranged into the second transport line, based on said first line information input and / or second line information input. The control unit can e.g. be configured to determine, based on the first and / or second line information input, whether the first line holder is loaded; and / or whether a first line holder should be unloaded; and / or whether a second line holder should be loaded.

[0023] For receiving the first and / or second line input information, the control unit can e.g. be configured to be communicatively connected to an operator input module configured to receive input from an operator; and / or a further control unit configured to control one or more components of the first and / or second transport line, respectively, and / or one or more sensors or measurements stations in the first and / or second transport line.

[0024] Optionally, the control unit is configured to control the first ejector and / or the second ejector, e.g. based on the first line information input and / or the second line information input. For example, the control unit can be configured to control a push element and / or an ejector actuator of the first and / or second ejector.

[0025] The control unit can be any type of suitable type of control unit, e.g. being embodied in a computer, PLC, raspberry pi, or the like. The control unit can be configured to control additional parts of the system, such as the conveyor systems of the first and / or second transfer line, or be configured to be in communication with additional control units for controlling such additional parts. The control unit can e.g. control the transfer conveyor and / or first ejector and / or second ejector directly, or indirectly by means of a further control unit configured to control the respective component(s) and be in communication with the control unit. The control unit can e.g. comprise one or more input terminals, output terminals, or communication terminals for communicating with other components. Said communication can be wired or wireless, according to any of suitable communication method or protocol, e.g. using Bluetooth or a Wi-Fi network.

[0026] In embodiments, the second transport line is configured to transport loaded and empty second line holders to the transport system. Thus, some of the second line holders are already loaded with a carcass part before arriving at the transfer system. The transfer mechanism is configured only transfer carcass parts to empty second line holders. In these applications the invention may be particularly advantageous, because the flexibility is increased by the possibility of changing the transfer positions.

[0027] In embodiments, the first transport line is configured to move the carcass part in a first line transport direction, and the second transport line is configured to move the carcass part in a second line transport direction, wherein transfer mechanism positioner is configured to move the first and / or second ejector (and optionally also the transfer conveyor with transfer holders, e.g. to move transfer mechanism as such) in a direction parallel to the first line transport direction and / or parallel to the second line transport direction. Thus, the different transfer positions can differ from each other by being further upstream or downstream in the first and / or second transport line. Optionally, the first line transport direction is parallel to the second line transport direction, optionally being opposite.

[0028] In embodiments, the first line transport direction and the second line transport direction are linear directions, and wherein optionally the first line transport direction and the second line transport direction are opposite directions of each other. The first and the second conveyor can thus both be linear conveyors.

[0029] In embodiments, the transfer system further comprises at least one elongate guide member having a longitudinal axis parallel to the first and / or second line transport direction, wherein the transfer mechanism positioner is configured to move the transfer mechanism (e.g. the first ejector and / or the second ejector and / or the transfer conveyor) over the elongate guide member(s). Optionally, the at least one elongate guide members includes a first elongate guide member and a second elongate guide member, e.g. extending parallel to each other. Optionally, the elongate guide member(s) are configured to support the transfer mechanism. Optionally, the elongate guide member(s) are configured to support the first and / or second ejector. Optionally, the elongate guide member(s) have a longitudinal length which is longer than at least four times the width of a first line holder and / or a second line holder, e.g. at least six times, e.g. at least ten times. Optionally, the elongate guide member(s) have a longitudinal length which is longer than the space occupied (i.e. including the width and the space between two subsequent holders) by at least four first line holders and / or a second line holders, e.g. at least six, e.g. at least ten.

[0030] The transfer system may further comprise at least one sliding element configured to slide overthe elongate guide member, for example one sliding element per elongate guide member. The sliding element(s) may e.g. be configured to support the first ejector, and / or the second ejector, and / or the transfer conveyor.

[0031] In embodiments, the first line transport direction and / or the second line transport direction are curved directions. For example, both the first and second line transport direction can be curved directions; but it is also possible that the first line transport direction is a curved direction and the second line transport direction is not (e.g. being a linear transport direction instead); and it is also possible that the second line transport direction is a curved direction and the first line transport direction is not (e.g. being a linear transport direction instead). The respective curved direction can e.g. be partially circular, e.g. covering at least 60 degrees or at least 90 degrees of a circular direction. The curved direction can e.g. comprise a center of curvature. The first and / or second transport line can e.g. part (or be configured to cooperate with) a carousel device. When both the first and second line transport direction are curved directions, it may be possible that have a parallel section where both curved directions extend parallel to each other, wherein the transfer mechanism is configured to move the carcass part from the parallel section of the first transport line to the parallel section of the second transport line.

[0032] In embodiments (e.g. wherein at least one of the first and second line transport direction is a curved direction), the transfer system further comprises a pivot arm, wherein the transfer mechanism (e.g. at least the first and / or second ejector but in some embodiments also the transfer conveyor with transfer holders) is connected to the pivot arm, wherein the transfer mechanism positioner is configured to move the pivot arm for moving the transfer mechanism (e.g. at least the first and / or second ejector but in some embodiments also the transfer conveyor with transfer holders) between the plurality of transfer positions. The pivot arm may e.g. define a pivot axis for the transfer mechanism, which may optionally coincide with a center of curvature of the curved direction of the first or second line transport direction. When the first or second transport line is part of (or cooperated with) a carousel device, the pivot arm may e.g. be connected to the carousel devices, e.g. to a center shaft of the carousel device. For example, the pivot arm may be configured to extend in horizontal direction, below and / or above the carcass parts, and be connected to the transfer mechanism by a vertically extending connection shaft. The transfer mechanism positioner may e.g. comprise a drive configured to move the pivot arm.

[0033] The pivot arm advantageously allows the transfer mechanism to be moved in a circular direction, which can be parallel to the curved direction of the first and / or second line transport direction. The transfer mechanism can as such be moved between different transfer positions (and thus the first line receiving positions and / or second line ejection positions).

[0034] In embodiments, the pivot arm is configured to move the transfer mechanism around a pivot axis, wherein the pivot axis coincides with a center of curvature of the curved direction of the first or second line transport direction, wherein optionally the first or second transport line is embodied as a carousel machine.

[0035] In embodiments, the transfer conveyor is configured to move the transfer holders in a closed loop, e.g. in a circular direction, an elliptical direction, or an oval direction. For example, the transfer conveyor may be a carrousel conveyor. For example, the transfer conveyor may be an endless conveyor. These embodiments are in particular advantageous because it avoids the need to move transfer holders back and forth between the first and second transport line by the same trajectory, and as such enable having multiple transfer holders following the same circular trajectory.

[0036] In embodiments, wherein the transfer mechanism positioner is configured to move the transfer mechanism (e.g. the first and / or second ejector, and optionally also the transfer conveyor with the transfer holders) between a first end position and second end position. The first end position may be the furthest position the transfer mechanism can be moved in one direction, and the second end position the furthest position in the opposite direction. Optionally, the first and / or second end positions correspond to a respective transfer position. Optionally, one or more transfer positions are possible between the first and second end position. Optionally, to move the transfer mechanism from the first end position to the second end position, a predetermined trajectory is followed, and to move the transfer mechanism back to the first end position, said predetermined trajectory is followed in the opposite direction. Said predetermined trajectory can e.g. be defined by the elongate guide member(s) and / or the pivot arm. Optionally, the first and second line transport directions are parallel to each other at least between the first end second end position.

[0037] In embodiments, the transfer holders are configured to support the carcass part by the feet and / or legs, e.g. comprising shackles configured to support the carcass part by the feet and / or legs.

[0038] In embodiments, the transfer holders comprise a cone-shaped support configured be arranged inside the carcass part for supporting the carcass part.

[0039] In embodiments, the transfer conveyor is configured to adapt the distance between subsequent transfer holders.

[0040] In embodiments, the control unit is configured to control the position of the transfer mechanism. The control unit can e.g. do this based on information relating to the carcass part. Various implementations of this are possible. For example, in embodiments, the control unit is configured to receive an identification signal for identifying the carcass part and / or the first line holder, wherein the control unit is configured to control the transfer mechanism positioner based on the identification signal. The identification of the carcass part and / or first line holder enables the control unit to determine the appropriate transfer position. For example, the control unit can comprise a memory configured to store information on the carcass and / or the first line holder, and / or the control unit can be configured to receive such information, e.g. from a control unit of another component or system. Said information can e.g. relate to the history, origin, performance, purpose, intended processing steps, prior measurements, etc, of the carcass part. For example, said information can relate to previous processing stations which have processed and / or analysed the carcass part.

[0041] In embodiments, the system further comprises an identification module configured to identify the first line holder or the carcass, and generate the identification signal. For example, the identification module can comprise an RFID-reader for reading an RFID-tag on the first line holder. For example, the identification module can comprise a code-reader for reading a code on the first line holder, said code e.g. being a barcode or QR-code. Optionally, the control unit is configured to match the identification signal to a first line holder or carcass part, e.g. based on information comprised by a memory. Optionally, the identification module is configured to match a reading to a first line holder or carcass part, such that the identification module comprises information about which holder or product has been identified. In embodiments, the first line holders each comprise an identifier. The identifier can e.g. be an RFID-tag, a barcode, or an QR-code.

[0042] In embodiments, the control unit is configured to receive a product assessment signal associated with the carcass part, and wherein the control unit is configured to determine whether or not to transfer the carcass part and / or in which transfer position, based on said product assessment signal. The product assessment signal may be based on an assessment of the carcass part. In embodiments, the product assessment signal is generated at a processing station upstream of the transfer system, e.g. upstream in the first transport line. For example, the control unit may be configured to receive the product assessment signal from an assessment station, wherein the assessment station is arranged upstream of the transfer system. For example, the first transport line may first transport the first product by the assessment station, and later by the transfer system.

[0043] In embodiments, the control unit is configured to determine for a carcass part to which second line holder it should be transferred, and control the transfer position (or at least the second line ejection position) based thereon. For example, it may be desired that in the second line carcass parts with certain similarities or differences in characteristics are arranged one behind the other. For example, in case legs of a slaughtered animal are being processed, it can be desired that left legs and right legs are arranged consecutively to each other.

[0044] In embodiments, the transfer system may be configured to transfer carcass parts between more than two transport lines. For example, the transfer system can be configured to receive carcass parts from more than one transport line and / or the transfer system can be configured to eject carcass parts to more than one transport line.

[0045] For example, in embodiments, the transfer system may be configured to receive carcass parts from a first transport line and a third transport line, and transfer the carcass parts to the second transport line. The plurality of transfer positions in which the transfer mechanism can be arranged includes at least one transfer position wherein the transfer holder is arranged in a first line receiving position for receiving a carcass part from a first line holder; and at least one transfer position wherein the transfer holder is arranged in a third line receiving position for receiving a carcass part from a third line holder of the third transport line.

[0046] The transfer mechanism (or at least the first ejector) can be moved by the transfer mechanism positioner over a distance that includes at least a position where the transfer holder is close to the first transport line (for the first line receiving position) and a position where the transfer holder is close to the third transport line (for the third line receiving position). The transfer mechanism positioner can e.g. move the first ejector in a linear direction, wherein the first and / or third transport line are parallel to said linear direction for a part thereof, and e.g. move perpendicular to said linear direction to move the first and third line holders, respectively, towards and / or away from the transfer mechanism.

[0047] The third transport line may further be embodied according to any of the embodiments described herein for the first transport line. The third transport line and first transport line may also be embodied similarly to each other. They may e.g. supply carcass parts that are processed in parallel to each other, e.g. at lower speed than in the second transport line.

[0048] For example, in embodiments, the transfer system may be configured to receive carcass parts from a first transport line, and transfer the carcass parts to the second transport line and to a fourth transport line. It is noted that although the term “fourth transport line” is used here, it is possible that the fourth transport line is present while there is no third transport line. The plurality of transfer positions in which the transfer mechanism can be arranged includes at least one transfer position wherein the transfer holder is arranged in a second line ejection position for ejecting a carcass part to a second line holder; at least one transfer position wherein the transfer holder is arranged in a fourth line ejection position for ejecting a carcass part to a fourth line holder of the fourth transport line.

[0049] The transfer mechanism (or at least the second ejector) can be moved by the transfer mechanism positioner over a distance that includes at least a position where the transfer holder is close to the second transport line (for the second line ejection position) and a position where the transfer holder is close to the fourth transport line (for the fourth line ejection position). The transfer mechanism positioner can e.g. move the second ejector in a linear direction, wherein the second and / or fourth transport line are parallel to said linear direction for a part thereof, and e.g. move perpendicular to said linear direction to move the second and fourth line holders, respectively, towards and / or away from the transfer mechanism.

[0050] The fourth transport line may further be embodied according to any of the embodiments described herein for the second transport line. The fourth transport line and second transport line may also be embodied similarly to each other. They may e.g. supply carcass parts that are processed in parallel to each other, e.g. at lower speed than in the first transport line.

[0051] A combination of the above embodiments is possible as well. Thus, in embodiments, the transfer system may be configured to receive carcass parts from the first transport line and the third transport line, and transfer the carcass parts to the second transport line and the fourth transport line.

[0052] The invention further relates to methods for transferring a carcass part from a first transport line to a second transport line. Although the method can be performed with the system according to the invention; neither the system, nor the method is limited thereto. Features explained herein with reference to the system have the same meaning with respect to the method unless explicitly defined otherwise. Features explained with reference to the system can be applied mutatis mutandis to the method to achieve the similar advantages.

[0053] One or more objects of the invention can e.g. be achieved with a method for transferring a carcass part from a first transport line to a second transport line, comprising a step of using a system according to any of the embodiments described herein. The method can e.g. comprise a step of using the transfer mechanism to move the carcass part from the first transport line to the second transport line, e.g. by first moving the carcass part from a first line holder to a transfer holder, and thereafter moving the carcass part from the transfer holder to a second line holder. The method can e.g. comprise a step of controlling the transfer mechanism positioner to arrange the transfer mechanism in a desired transfer position.

[0054] One or more objects of the invention can e.g. be achieved with a method for transferring a carcass part from a first transport line to a second transport line, comprising one or more of the following steps: • controlling a position of at least a first ejector and / or a second ejector (optionally a position of a transfer mechanism, e.g. further including a transfer conveyor and transfer holders) between a plurality of transfer positions;

[0055] • transferring the carcass part from a first line holder of the first transport line into a transfer holder of the transfer mechanism, when the transfer holder is in a first line receiving position;

[0056] • moving the transfer holder from the first line receiving position to a second line ejection position;

[0057] • transferring the carcass part from the transfer holder into a second line holder of the second transport line, when the transfer holder is in the second line ejection position; wherein between said plurality of transfer positions the first line receiving positions are different and / or the second line ejections positions are different.

[0058] The invention further relates to non-transitory computer-readable instructions configured to, when executed, cause a control unit of a system for for transferring a carcass part from a first transport line to a second transport line to perform the method according to any of the embodiments described herein. Said transfer system may e.g. be according to any of the embodiments described herein. In particular, the computer readable instructions may cause the control unit to control components of the transfer system to perform the steps of the method, in particular the respective steps performed by those components. For example, the control unit may control one or more (or all) of: the transfer mechanism positioner; the transfer mechanism, the first ejector, the second ejector; the transfer holders and / or the transfer conveyor.

[0059] For example, the non-transitory computer readable instruction may be configured to, when executed, cause a control unit of a transfer system for transferring a carcass part from a first transport line to a second transport line to:

[0060] • control a position of at least a first ejector and / or a second ejector (optionally a position of a transfer mechanism, e.g. further including a transfer conveyor and transfer holders) between a plurality of transfer positions;

[0061] • control the first ejector for transferring the carcass part from a first line holder of the first transport line into a transfer holder of the transfer mechanism, when the transfer holder is in a first line receiving position;

[0062] • control the transfer conveyor for moving the transfer holder from the first line receiving position to a second line ejection position;

[0063] • control the second ejector for transferring the carcass part from the transfer holder into a second line holder of the second transport line, when the transfer holder is in the second line ejection position; wherein between said plurality of transfer positions the first line receiving positions are different and / or the second line ejections positions are different.

[0064] A second aspect of the invention is elaborated on below. The second aspect also relates to a transfer system; method for transferring a carcass part from a first transport line to a second transport line, and non-transitory computer readable instructions. Features referenced with respect to the second aspect may be embodied and / or comprise any of the features or elements explained with respect to the first aspect, unless explicitly mentioned otherwise. All details of will therefore not be repeated to explain the second aspect.

[0065] According to the second aspect, one or more objects of the invention are achieved with a transfer system for transferring a carcass part from a first transport line to a second transport line, the transfer system comprising:

[0066] • a transfer mechanism comprising:

[0067] • a plurality of transfer holders for holding a carcass part;

[0068] • a transfer conveyor configured to move the transfer holders between at least the first line receiving position and the second line ejection position;

[0069] • a first ejector mechanism, configured to eject the carcass part from a first line holder of the first transport line into one of the transfer holders, when said transfer holder is arranged in the first line receiving position;

[0070] • a second ejector mechanism, configured to eject the carcass part from the transfer holder into a second line holder of the second transport line, when said transfer holder is arranged in the second line ejection position; wherein:

[0071] • the first ejector mechanism comprises a plurality of first ejectors configured to be selectively used for ejecting the carcass part for changing the first line receiving position; and / or

[0072] • the second ejector mechanism comprises a plurality of second ejectors configured to be selectively used for ejecting the carcass part for changing the second line ejection position

[0073] Thus, the transfer system according to the second aspect comprises a first ejector mechanism and a second ejector mechanism. At least one of the first and second ejector mechanism comprises a plurality of ejectors. Said ejectors can e.g. be arranged next to each other. Said ejectors can e.g. be arranged downstream of each other in the conveyance path of a carcass part that is not ejected. That is, if the most upstream ejector of the plurality of ejectors is not used, the carcass part with pass a more downstream ejector. If that ejector is not used either, the carcass part will pass a further downstream ejector, and so on. Optionally, each ejector is configured to eject the carcass part on its own, i.e. without cooperation with other ejectors.

[0074] By selecting which of the respective ejectors to use, the first line receiving position or the second line ejection position can be changed. This allows to achieve similar advantages as explained with reference to the first aspect. The first ejectors and / or are configured to remain stationary and / or in position (except for movement to eject the carcass part). As explained below, the second aspect can be used in combination with a transfer conveyor that is moved as whole (as explained in some embodiments of the first aspect) as well as a transfer conveyor that remains stationary as a whole (e.g. still having the transfer shackles move in an endless loop trajectory). In embodiments, the transfer conveyor is configured to transport the carcass part in a transfer transport path, wherein the transfer transport path comprises a first section parallel to the first transport line and wherein the plurality of first ejectors are arranged next to each other along the first section; and / or wherein the transfer transport path comprises a second section parallel to the second transport line, wherein the plurality of second ejectors are arranged next to each other along the second section.

[0075] For example, the transfer transport path can have a fixed trajectory in this embodiments, i.e. a trajectory that is not moved as a whole relative to the first transport line and the second transport line. For example, the transfer transport path can be oval in these embodiments.

[0076] In embodiments, the transfer system further comprises a transfer mechanism positioner configured to move the transfer conveyor relative to the first transport line and the second transport line. Optionally the movement of the transfer conveyor is a movement of the transfer conveyor as a whole; and / or the transfer conveyor is configured to move the transfer holders in a trajectory, and the movement of the transfer conveyor by the transfer mechanism positioner is configured to change the position of said trajectory relative to the first transport line and the second transport line.

[0077] These embodiments can be advantageous to adapt the first line receiving position and / or second line ejection position by moving the transfer conveyor as a whole; however since a plurality of first and / or second ejectors are provided, there is no need to move said ejectors as well. It is noted that these embodiments can imply a combination of the first and second aspect invention. For example, the one of the first and second ejector mechanism comprises a plurality of ejectors as in the second aspect, while the other comprises an ejector being moved by the transfer mechanism positioner as in the first aspect.

[0078] In embodiments, the transfer system further comprises a control unit, wherein the control unit is configured to control the transfer mechanism for controlling which of the plurality of first ejectors is used and / or which of the plurality of second ejectors is used.

[0079] In embodiments, the control unit is configured to receive a first line information input and / or a second line information input, and control the transfer mechanism based on the first line information input and / or the second line information input. Optionally control the first ejector mechanism and / or the second ejector mechanism based on the first line information input and / or the second line information input.

[0080] In embodiments, the first transport line is configured to move the carcass part in a first line transport direction, wherein the plurality of first ejectors are arranged next to each other along the first line transport direction, and / or the second transport line is configured to move the carcass part in a second line transport direction, wherein the plurality of second ejectors are arranged next to each other along the second line transport direction.

[0081] In embodiments, the first line transport direction and the second line transport direction are linear directions, and wherein optionally the first line transport direction and the second line transport direction are opposite directions of each other. The first and the second conveyor can thus both be linear conveyors. In embodiments, the transfer conveyor is configured to move the transfer holders in a closed loop, e.g. in a circular direction, an elliptical direction, or an oval direction. For example, the transfer conveyor may be a carrousel conveyor. For example, the transfer conveyor may be an endless conveyor.

[0082] In embodiments, the transfer system may be configured to transfer carcass parts between more than two transport lines. For example, the transfer system can be configured to receive carcass parts from more than one transport line and / or the transfer system can be configured to eject carcass parts to more than one transport line. For example, the transfer system can comprise a third ejector mechanism comprising a plurality if third ejectors.

[0083] In embodiments, the second aspect can relate to the first and / or second ejector mechanism as described above. For example, the second aspect can relate to an ejector mechanism comprising a plurality of ejectors, each ejector being configured to move a carcass part from a first transport line or transfer line to a second transport or transfer line, wherein the plurality of ejectors are arranged next to each other and downstream of each other when seen in the transport direction of the first transport line or transfer line, wherein (a control unit of) the ejector mechanism is configured to select an ejection position by selecting one of the ejectors to move the carcass move a carcass part from a first transport line or transfer line to a second transport or transfer line.

[0084] The second aspects further relates to methods for transferring a carcass part from a first transport line to a second transport line. Although the method can be performed with the system according to the invention; neither the system, nor the method is limited thereto. Features explained herein with reference to the system have the same meaning with respect to the method unless explicitly defined otherwise. Features explained with reference to the system can be applied mutatis mutandis to the method to achieve the similar advantages.

[0085] One or more objects of the invention can e.g. be achieved with a method for transferring a carcass part from a first transport line to a second transport line, comprising a step of using a system according to any of the embodiments described herein. The method can e.g. comprise a step of selecting which first ejector of a first ejector mechanism to use and / or which second ejector of a second ejector mechanism to use.

[0086] One or more objects of the invention can e.g. be achieved with a method for transferring a carcass part from a first transport line to a second transport line comprising the following steps:

[0087] • controlling which first ejector of a first ejector mechanism having a plurality of first ejectors to select and use; and / or controlling which second ejector of a second ejector mechanism having a plurality of second ejectors to select and use;

[0088] • transferring the carcass part from a first line holder of the first transport line into a transfer holder of the transfer mechanism using the selected first ejector, when the transfer holder is in a first line receiving position;

[0089] • moving the transfer holder from the first line receiving position to a second line ejection position; transferring the carcass part from the transfer holder into a second line holder of the second transport line using the selected second ejector, when the transfer holder is in the second line ejection position

[0090] The second aspect further relates to non-transitory computer-readable instructions configured to, when executed, cause a control unit of a system for for transferring a carcass part from a first transport line to a second transport line to perform the method according to any of the embodiments described herein. Said transfer system may e.g. be according to any of the embodiments described herein. In particular, the computer readable instructions may cause the control unit to control components of the transfer system to perform the steps of the method, in particular the respective steps performed by those components. For example, the control unit may control one or more (or all) of: the first ejector mechanism, the second ejector mechanism; the transfer mechanism, the transfer holders and / or the transfer conveyor.

[0091] For example, the non-transitory computer readable instruction may be configured to, when executed, cause a control unit of a transfer system for transferring a carcass part from a first transport line to a second transport line to:

[0092] • controlling which first ejector of a first ejector mechanism having a plurality of first ejectors to select and use; and / or controlling which second ejector of a second ejector mechanism having a plurality of second ejectors to select and use;

[0093] • transferring the carcass part from a first line holder of the first transport line into a transfer holder of the transfer mechanism using the selected first ejector, when the transfer holder is in a first line receiving position;

[0094] • moving the transfer holder from the first line receiving position to a second line ejection position;

[0095] • transferring the carcass part from the transfer holder into a second line holder of the second transport line using the selected second ejector, when the transfer holder is in the second line ejection position.

[0096] Exemplary embodiments of the invention are described using the figures. It is to be understood that these figures merely serve as example of how the invention can be implemented, and are in no way intended to be construed as limiting for the scope of the invention and the claims. Like features are indicated by like reference numerals along the figures. In the figures:

[0100] Fig. 3B schematically illustrates a transfer system according to a third embodiment in a top view; Fig. 4 schematically illustrates a transfer system according to a fourth embodiment from below;

[0101] Fig. 5 schematically illustrates the working principles of a control unit of a transfer system;

[0102] Fig. 6 schematically illustrates a transfer system according to a second aspect.

[0103] Fig. 1 schematically illustrates a transfer system 1 according to a first embodiment in a top view. The transfer system 1 is arranged between a first transport line 100 and a second transport line 200. The main function of the transfer system 1 is to transfer carcass parts 301 , 302, 303 between the first and second transport lines 100,200, in particular from the first transport line 100 to the second transport line 200.

[0104] In the shown example, the carcass parts 301 , 302, 303 are poultry carcass parts 301 , 302, 303. However, it will be understood that the invention can also be applied to other types of carcass parts. In the shown example, the carcass parts 301 , 302, 303 comprise are complete carcasses, but it will be understood that this is not necessary and the invention can be applied to different types of carcass parts comprising only parts of the carcass, e.g. back halves, front halves, legs, breast, etc. In the shown example, first line holders 1 10, transfer holders 12, and second line holders 210 are embodied as shackles configured to hold the carcass parts 301 , 302, 303 by the legs, but it will be understood that other types of holders can be used as well, e.g. trays or containers.

[0105] The first transport line 100 transports the carcass parts 301 in a linear direction indicated by arrow 101 . The first transport line 100 comprises a plurality of first line holders 1 10 each configured to hold a carcass part 301 , in this case by the legs. Similarly, the second transport line 200 transports the carcass parts 303 in a linear direction indicated by arrow 201 . The second transport line 200 comprises a plurality of second line holders 210 each configured to hold a carcass part 302, in this case also by the legs. Although fig. 1 is a simplified schematic illustration, the skilled person will understand that the transport lines 100,200 may comprise an overhead conveyor with e.g. a (endless) transport chain which is connected to the first or second line holders 1 10, 210, respectively, and configured to be moved for moving the respective holders 1 10,210. Details of the first and second transport line 100, 200 will not be elaborated on too much, since this can be any suitable types of transport systems, of which the skilled person has sufficient knowledge to implement.

[0106] It may be necessary to transport the carcass parts 301 , 302, 303 from the first transport line 100 to the second transport line 200. This can be for various reasons, but usually the second transport line 200 will usually transport the carcass part 303 to other processing stations. In some cases only some of the carcass parts 301 in the first transport line 100 should be transferred to the second transport line 200, depending on how they should be processed further downstream. In some cases the second transport line 200 is embodied differently from the first transport line 100 in ways that are required for downstream processing steps. In the shown example, a distance 221 between two second line holders 210 is larger than a distance 121 between two first line holders 1 10. In may also be possible that the carcass part 303 is held differently by the second line holder 210 when compared to the carcass part 301 being held by the first line holder 1 10.

[0107] The transfer system 1 comprises a transfer mechanism 10, which comprises a first ejector 21 , a second ejector (not visible in fig. 1 ), a plurality of transfer holders 12, and a transfer conveyor 1 1 for moving the transfer holder 12. The transfer holders 12 are moved in a closed loop, in particular in a circular direction by the transfer conveyor 1 1 , as indicated by arrow 13.

[0108] Each transfer holder 12 can in particular be arranged in a first line receiving position, wherein it is arranged close to the first transport line 100 and ready to receive a carcass part 301 . The first ejector21 can then be moved to force (e.g. by pushing) the carcass part 301 out of the first line holder 1 10 and into the transfer holder 12. The carcass part 301 is in that case moved in the direction indicated by arrow 22. Said transfer holder 12 is then moved by the transfer conveyor 1 1 to a second line ejection position, wherein it is arranged close to the second transport line 200. The second ejector can then be moved to force (e.g. by pushing) the carcass part 301 out of the transfer holder 12 and into the second line holder 210, e.g. in the direction of arrow 32. The second ejector is not visible in fig. 1 because it is arranged below the visible components of the transfer conveyor 1 1. The first and second ejector 21 can both be embodied according to known principles.

[0109] The transfer system 1 further comprises a transfer mechanism positioner, which can be used to adjust the first line receiving position and / or the second line ejection position. Thus, the transfer mechanism positioner can adjust the position / location where the poultry carcass 301 is transferred from the first transport line 100 to the transfer mechanism 10; and / or the transfer mechanism positioner can adjust the position / location where the poultry carcass 302 is transferred from the transfer mechanism 10 to the second transport line 200.

[0110] In the example shown in fig. 1 , the transfer mechanism positioner is configured to move the transfer mechanism 10 as a whole. That is, the first ejector 21 , second ejector, transfer conveyor 1 1 , and transfer holders 12 simultaneously. The transfer mechanism positioner comprises two elongated guides 44, 45 and two sliding elements 42, 43 which are connected to each other by a connecting plate 41 . The transfer conveyor 1 1 with the transfer holders 12 is connected to the sliding elements 42, 43 and / or connecting plate 41 . Although not explicitly shown in the figure, the first 21 and second ejector are also connected to the sliding elements 42, 43 and / or connecting plate 41 . This can be achieved with intermediate connecting elements if necessary.

[0111] A drive (not shown in this figure) is functionally connected to the connecting plate 41 for moving said connecting plate 41 and all components connected thereto. The sliding elements 42, 43 allow movement relative to the elongated guides 44, 45. As such, the transfer mechanism positioner can move the transfer mechanism 10 (with transfer conveyor 1 1 , transfer holders 12, first ejector 21 , and second ejector) relative to the first transport line 100 and the second transport line 200, in the directions indicated by arrows 51 , 52. The first line receiving position and second line ejection position can as such be changed, which advantageously increases the flexibility of the transfer system 1. Fig. 1 illustrates that the first line transport direction 101 of the first transport line 100 is parallel to the second line transport direction 201 of the second transport line 200, at least for the part where the transport system is present. In this case said transport directions 101 , 201 are also opposite, but in other cases they may be in the same direction. The directions 51 , 52 in which the transfer mechanism 10 can be moved, are also parallel to both transport directions 101 , 201. This is achieved by the fact that the elongate guide members 44, 45 each have a longitudinal axis that is parallel to the first and second line transport direction 101 , 201.

[0112] Fig. 2A-2F show a schematically illustration of one of the applications wherein the transfer system can provide advantages. The first transport line 100 and the second transport line 200 are schematically illustrated, as well as the transfer mechanism 10. An elongated guide 48 over which the transfer mechanism 10 can be moved is schematically illustrated as well.

[0113] In fig. 2A no poultry carcasses are present yet in the shown parts of the first 100 and second transport line 200. The transfer mechanism 10 is arranged in a rest position, which can be anywhere along the elongated guide 48.

[0114] In fig. 2B, it can be seen that several carcass parts 151 , 152, 153, 154, 155, 156, 157 are being transported by the first transport line 100. Some of those, in particular carcass parts 151 and 154 should be transferred to the second transport line 200, while the other should not. Which carcass parts should be transferred can e.g. depend on observations or measurements done previously, e.g. upstream in the first transport line 100 at a measurement station and / or a processing station. The second transport line 200 also transports several carcass parts 251 , 252. These carcass parts 251 , 252 can e.g. be transferred upstream in the second transport line 200 from yet another transport line. In fig. 2B, the transfer mechanism 10 has been moved over the elongated guide 48 to the (in the figure) right-hand side.

[0115] In fig. 2C-2D, carcass parts 151 and 154 have been transferred (by the first ejector) from the first transport line 100 to the transfer mechanism. It can be seen that the transfer mechanism 10 has not yet transferred the carcass part 154 to the second transport line 200, but instead is acting as a buffer that is gradually being filled with carcass parts. In the meantime a further carcass part 158 to be transferred is also visible in fig. 2D.

[0116] In fig. 2D, said carcass part 158 is moved to the transfer mechanism 10. The carcass part 151 is meanwhile in the second line ejection position, and can thus be moved to the second transport line 200. Fig. 2E and 2F show situations a bit later, wherein the second transport line 200 is filled further. The transfer mechanism 10 is moved along the elongate guide 48.

[0117] In the shown application, there should be, on the one hand, an empty transfer holder in the first line receiving position when a carcass part to be transferred in the first transport line 100 passes the transfer mechanism. On the other hand, before the transfer conveyor (in particular the transfer holders) is being rotated in the transfer direction, the carcass part in the transfer holder that is in the second line ejection position is preferably transferred to the second transport line. In other words, the respective transfer holder should be emptied. However, this requires an empty second line holder being able to receive said carcass part. The moving of the transfer mechanism 10 provides more flexibility to achieve this, or move to another first line receiving position and / or second line ejection position if required. At any given moment, the position of the transfer mechanism 10 on the elongate guide 48 may be controlled in function of the availability of second line holder to transfer a carcass part to, as well as which carcass parts in the first transport line 100 should be transferred to a transfer holder. As illustrated in fig. 2F, this may enable to fill a high percentage of the second line holders, which thus increases the throughput of carcass parts in the second transport line. It can also be possible to control the transfer system in function of desired arrangement of carcass parts in the second transport line 200. It can for example be desired to have left and right legs being arranged consecutively in the second transport line 200. Other requirements based on which the order in the second transport line 200 is decided are possible as well.

[0118] In fig. 2A-2F the carcass parts can be conveyed in shackles as indicated in other figures, but other holders 253 are also possible, e.g. trays 253 or containers 253.

[0119] Fig. 3A schematically illustrates a transfer system 2 according to a second embodiment in a top view. Fig. 3A again schematically illustrates a first transport line 100 and a second transport line 200. The first transport line 100 comprises a plurality of first line holders 1 10 which are moved by a conveyor 1 1 1. The second transport line 200 comprises a plurality second line holders 210 which are moved by a conveyor 21 1. The first line holders 1 10 and second line holders 210 are configured to transport carcass part, which may e.g. be poultry carcass parts.

[0120] A transfer mechanism 60 is configured to transfer the carcass part from the first transport line 100 to the second transport line 200. The transfer mechanism 60 comprises a first ejector 61 , a second ejector 62, a transfer conveyor 65, and a plurality of transfer holders 66. The first ejector 66 which is configured to push a carcass part out of a first line holder 1 10 and into a transfer holder 66. The transfer holder 66 receiving the carcass part is arranged in a first line receiving position. The transfer holder 66 is then moved, while holding the carcass part, by the transfer conveyor 65. Eventually, the transfer holder 66 reaches a second line ejection position. This is the location where the carcass part can be pushed out of the transfer holder 66 by the second ejector 62, and into a second line holder 210.

[0121] Similarly as explained with reference to the previous figures, the transfer system 2 comprises a transfer mechanism positioner configured to adjust the first line receiving position and / or the second line ejection position. However, this time not the complete transfer mechanism is moved simultaneously. The transfer mechanism 60 comprises a transfer mechanism positioner. The transfer mechanism positioner comprises a first elongate guide 63 over which the first ejector 61 can be moved, and a second elongate guide 64 over which the second ejector 62 can be moved. The transfer mechanism positioner further comprises a first drive (not shown) for moving the first ejector 61 and a second drive (not shown) for moving the second ejector 62. Furthermore, the transfer conveyor 65 does not transport the transfer holders 66 in a pure circular transfer path but rather in an elongated transfer path. The transfer path has a first linear section 65a which is parallel to the transport direction of the first transport line 100, and a second linear section 65b which is parallel to the transport direction of the second transport line 200. It can be seen that the length of the first and second elongate guide 63, 64 correspond approximately with the length of the first and second linear sections 65a, 65b. The embodiment shown in fig. 3A allows to move the first ejector 61 along the first elongate guide 63 to change the first line receiving position. Indeed, whenever a transfer holder 66 is arranged aligned with the first ejector 61 , it can be considered to be in the first line receiving position. Similarly, the second ejector 62 can be moved along the second elongate guide 64 to change the second line ejection position. Although it may be possible that in some embodiments the first and second ejector 61 ,62 are moved simultaneously (e.g. by a single drive), it may also be possible that the first and second ejector 61 , 62 can be positioned independently of each other. This further improves the flexibility of the system.

[0122] Fig. 3B schematically illustrates a transfer system according to a third embodiment in top view. In this embodiment, the transfer system is configured to transfer carcass parts from the first transport line 100 to a second transport line 700 and a fourth transport line 800. The first transport line 100 and the transfer mechanism are embodied the same as shown in fig. 1. Differently than in fig. 1 , however, is that in some transfer positions the second ejector will eject the carcass part to a second line holder 710 of the second transport line 700, and in other transfer positions the second ejector will eject the carcass part to a fourth line holder 810 of the fourth transport line 800.

[0123] The second and fourth transport line 700, 800 have respective conveying directions 71 1 , 81 1 which are parallel to the elongated guides 44, 45 for a part thereof. This allows to do the respective transfers on when the transfer mechanism is moved to those respective parts of the elongated guides 44,45. The conveying direction 71 1 , 81 1 further run perpendicular to the elongated guides 44, 45 to move the holders 710, 810 to and away from the transfer mechanism. However, other configurations are possible as well. In the shown example the second transport line 700 has a longer parallel section with the elongated guides 44, 45 than the fourth transport line 800, which may be advantageous if more carcasses will be moved to the second transport line 700. However, other configurations are possible.

[0124] Embodiments as the one shown in fig. 3B can have several advantageous applications. For example, the speed at which the second 700 and fourth transport line 800 transport and process the carcass parts may be different than in the first transport line 100.

[0125] In addition or alternatively to having the second and fourth transport line 700, 800 as shown in fig. 3B, similar arrangements with two incoming transport lines (the first and a third transport lines) are possible.

[0126] Fig. 4 schematically illustrates a transfer system 3 according to a fourth embodiment from below. A first transport line 300 in this case is part of a so-called carrousel device 301 (also called turret device). The first transport line 300 comprises a plurality of first line holders 312 that are configured to hold a carcass part 555 (in this case a complete poultry carcass) by the legs. Being part of a carousel device 301 , the first line holders 312 are moved in a circular transport direction, as illustrated by arrow 315. The first line holders 312 are connected to each other by a chain 310 which is moved to move the first line holders 312. Rollers 31 1 are moved over a guide (not shown) to ensure correct positioning of the first line holders 312. Similar principle with a chain and / or rollers with guide can be applied to linear transport lines as shown in previous figures, but in both types of transport lines other configurations are possible as well. A carousel device 301 may be advantageous for various reasons and for various processing steps, but are usually only used fora single processing step. The carcass parts 555 are in some cases first transferred from an upstream conveyor into the carousel device 301 . When the processing step has been completed, the carcass part 555 should be taken out of the carrousel device 301 again and moved to another transport line. The example shown in fig. 4 illustrates an application of a transfer system 3 for moving the carcass part 555 out of the carrousel device, but it will be understood that similar principes can be applied for arranging the carcass part 55 into the carrousel device 301.

[0127] In the shown example, the carcass parts 55 are transferred to a second transport line 400. The second transport line 400 comprises a plurality of second line holders 41 1 configured to hold the carcass part 55 by the legs. The second line holders 41 1 are configured to move the carcass parts 55 in a second line transport direction 415. For at least a part of the second transport line 400 (that is in the vicinity of the first transport line 300), said second line transport line is curved, as illustrated by arrows 415. For a part, the second line transport direction 415 is parallel to the first line transport direction 315.

[0128] A transfer mechanism 500 is configured to move the carcass parts 555 from the first transport line 300 to the second transport line 500. The transfer mechanism 500 comprises a transfer conveyor 501 with a plurality of transfer holders 502. A first ejector (not shown) can move a carcass part 555 from a first line holder312 into a transfer holder 502, as illustrated by arrow 51 1 . Said transfer holder 51 1 is at that moment in a first line receiving position. The transfer conveyor 501 can then move said transfer holder 51 1 (in a circular direction) to a second line ejection position.
