Abstract
Description
Technical Field
[0001] The present invention relates to a device for removing meat from poultry, in particular a device for removing poultry back meat from the poultry chest of a slaughtered poultry. The present invention also relates to a poultry carrier for said device. The present invention also relates to a method for removing meat from poultry, in particular a method for removing poultry back meat from the poultry chest, in particular by using the device according to the present invention. Background Art
[0002] In order to divide slaughtered poultry into parts attractive to consumers, the poultry is usually supplied to the cutting line of a poultry processing plant. In this line, the poultry is conveyed by a conveyor guided past a plurality of processing stations. However, especially for harvesting back meat from the carcass parts of slaughtered poultry, known devices and methods only yield a small part of the back meat, such as for example two outer meat slices, while requiring relatively complex and / or inefficient and generally rather expensive equipment. Summary of the Invention
[0003] A first object of the present invention is to provide an improved poultry meat harvesting device and method.
[0004] A second object of the present invention is to provide an improved poultry back meat harvesting device and method.
[0005] A third object of the present invention is to provide a relatively efficient poultry meat (especially poultry back meat) harvesting device and method.
[0006] A fourth object of the present invention is to provide a poultry meat (especially poultry back meat) harvesting device having a relatively compact and / or efficient design.
[0007] At least one of these objects can be achieved by a device according to the preamble, the device comprising:
[0008] - at least one conveyor, in particular a ring conveyor, for conveying poultry pieces along a conveying path;
[0009] - at least one poultry carrier, said at least one poultry carrier being attached to said conveyor and / or forming part of said conveyor, wherein each poultry carrier is configured to carry and / or support at least one poultry piece, in particular at least a part of a poultry chest (carrier), to which poultry back meat is attached,
[0010] - At least one pre-cutting section, said at least one pre-cutting section being arranged along the conveying path of the conveyor, said at least one pre-cutting section including at least one pre-cutting element, said at least one pre-cutting element being positioned such that at least a part of the poultry meat is partially separated from the remaining part of the poultry, in particular wherein at least a part of the poultry back meat is partially separated from the poultry chest cavity, and,
[0011] - At least one meat separation section, arranged downstream of the pre-cutting section along the conveying path of the conveyor, said meat separation section including at least one rotatable cutting element for forming a separation cut to separate the at least one pre-cut poultry part from the remaining poultry part, in particular to completely separate the pre-cut poultry back meat from the poultry chest cavity. Preferably, the meat separation section is further configured to physically remove the separated poultry part from the remaining poultry part at least in a direction away from the conveying path, in particular to physically remove the separated poultry back meat from the poultry chest cavity.
[0012] Thus, the device according to the invention constitutes a poultry meat (in particular poultry back meat) harvesting device and method for harvesting back meat from the carcass part of a slaughtered poultry (in particular a chicken). The device according to the invention allows the harvesting of back meat with good quality in terms of meat structure and yield, and allows, for example, separating almost the entire back meat part as a single outer slice from the chest cavity. Compared with the prior art, this results in larger slice sizes, and also results in an increased yield in the (back) meat harvesting process and thus reduced meat waste. Therefore, the device according to the invention can also be considered a slicing device.
[0013] During the transportation of the poultry on / by the conveyor along different processing stations, the poultry is preferably oriented in an upright position with the breast side downwards, preferably wherein the fillet or back meat is substantially horizontally oriented. Preferably, during transportation, at least a part of each piece of poultry is located above the conveyor, wherein the conveyor supports at least a part of each piece of poultry. This results in a situation where the back meat part of the poultry chest cavity (poultry carcass) is positioned on top, and due to the positioning below the conveyor, a working space is formed above and around the back meat part to accurately separate this back meat part from the chest cavity in successive steps. This reduces the constraints of the cutting process and thus allows a more controlled cutting process. In addition, due to the low positioning of the conveyor, the cutting stations (such as the pre-cutting section and the separation section) can be easily installed and positioned, resulting in a relatively efficient and possibly simple device design. The separation section preferably includes a single rotatable cutting element. The single rotatable cutting element is preferably axially rotatable about a rotation axis that actually intersects the conveying path. This means that the rotatable cutting element defines a plane having at least one direction component parallel to the conveying path, for example a horizontal component parallel to the horizontal conveying path.
[0014] The pre-cutting section is preferably configured to form at least one pre-cut on the poultry, which extends in a direction parallel to the conveying direction of the poultry through the pre-cutting section. Preferably, the pre-cutting section includes a plurality of pre-cutting elements positioned at a mutual distance from each other, where the mutual distance is preferably greater than 0.5 cm, such as greater than 1 cm and / or where the mutual distance is preferably less than 5 cm. According to this preferred embodiment, in the pre-cutting section, (at least) two incisions are formed in the back meat, one on each side of the spine (vertebral column). At or around the spine, the back meat remains attached to the spine in the pre-cutting section and will be cut (and separated) in the downstream separating section. The width of the uncut portion of the back meat portion adjacent to the spine is preferably defined by the distance between opposite, spaced-apart pre-cutting elements. One or more pre-cutting elements can be and preferably are stationary pre-cutting elements. It is conceivable that at least one pre-cutting element includes at least one non-linear blade portion, such as an angled and / or curved blade portion, preferably a concave-curved blade portion. The blade portion is preferably configured to follow at least a part of the upper side of the chest cavity and thus at least a part of the back meat portion. Preferably, at least one pre-cutting element is configured to pre-cut the poultry such that two spaced-apart poultry meat flaps are formed at opposite sides of the uncut portion of the poultry, and / or where at least one pre-cutting element is configured to pre-cut the back of the poultry such that two spaced-apart poultry back meat wings are formed at opposite sides of the spine (main trunk) of the poultry chest cavity. A third cut is made by the separating section to preferably separate the back meat portion as at least one outer meat slice (optionally, the back meat wings still attached to each other) from the chest cavity. It is conceivable that at least one pre-cutting element, preferably each pre-cutting element, is elastically and / or rotatably attached to the device. Preferably, where the pre-cutting element is elastically pivotable or rotatable about a pivot axis that extends substantially parallel to the conveying path. Preferably, the pivot axis is positioned below and / or at a lateral distance from the conveying path relative to the conveying path. The pivotable pre-cutting element allows for small deviations between poultry blocks to be taken into account. For example, not every chest cavity has the same size. Thus, in the case of a slightly larger chest cavity, the pre-cutting element can be forced outwards to account for the larger size. Preferably, the pre-cutting element has a first maximum position where the pre-cutting element is closest to the conveying path, preferably, this position (or a further inward rotational movement) is physically or mechanically determined and / or defined. To this end, the pre-cutting section can include at least one stop for stopping the rotational movement of the pre-cutting element in the downward direction. Thus, the stop defines the stationary position of the pre-cutting element. The poultry chest cavity can cause the pre-cutting element to move outwards relative to the stop and elastically return the pre-cutting element to the stationary position as the chest cavity passes the pre-cutting element.
[0015] The at least one pre-cutting element is preferably aligned with the rotatable cutting element of the separating part, in particular in terms of height. Preferably, the highest edge of the at least one pre-cutting element is positioned at the same level or at a higher level compared to the cutting position of the rotatable cutting element. This alignment preferably allows for a smooth, direct or indirect connection between the two parts, which is beneficial for the meat cutting process.
[0016] In a preferred embodiment, the device further comprises at least one poultry meat product alignment part, which is arranged between the pre-cutting part and the meat separation part and is used to align the poultry, in particular at least one pre-cut poultry part, relative to the rotatable cutting element of the separation part. Such an intermediate part can further facilitate the processing of poultry along the different parts mentioned in this section on the conveying path. Preferably, the alignment part comprises at least one alignment element, preferably at least two alignment elements spaced apart from each other, so as to move at least a part of the pre-cut (separated) poultry part away from the remaining poultry part, thereby forming at least one space between the pre-cut poultry part and the remaining poultry part. Such one or more spaces will generally contribute to a smooth and precise cutting process in the downstream separation part. It is conceivable that at least one alignment element, preferably at least two alignment elements spaced apart from each other, is configured to lift at least one pre-cut poultry meat part in a direction away from the remaining poultry meat part to form the at least one space. It is envisaged that at least one alignment element, preferably each alignment element, is configured as a guide rod for guiding the pre-cut poultry meat part and / or a slide rod for allowing the pre-cut poultry meat part to slide on the slide rod and / or be pulled (by the conveyor). Preferably, at least one alignment element is aligned with the rotatable cutting element of the separation part. Preferably, at least a part of the highest edge of at least one alignment element is located at the same level or a higher level as the cutting position of the rotatable cutting element. Such alignment will generally ensure a smooth transition of the poultry from the alignment part to the separation part. Preferably, at least a part of the highest edge of at least one alignment element is located at substantially the same level or a lower level compared to at least one pre-cutting element. Such alignment will generally ensure a smooth transition of the poultry from the pre-cutting part to the alignment part. The alignment part is preferably connected to the pre-cutting part and the separation part and / or any other part of the device, and / or is positioned directly adjacent to the pre-cutting part and the separation part and / or any other part of the device. Such connection does not mean that these parts are in direct physical contact with each other, but rather these parts are positioned close to each other, where an optional intermediate gap is, for example, less than 1 cm, preferably less than 0.5 cm, more preferably less than 0.3 cm. Preferably, the side of the alignment part facing the rotatable cutting element is at least partially concave-curved. The curvature of the curved side of the alignment part preferably substantially corresponds to the curvature of the (circular) circumferential edge of the cutting element of the separation part. The axially rotatable cutting element (such as a cutting disc) of the separation part is configured to make a cut in the horizontal direction and / or in a direction parallel to the conveying path.
[0017] Preferably, the poultry meat product alignment section includes two spaced-apart alignment elements that define a slotted passage therebetween for passage of an uncut portion of the poultry, where the uncut portion is preferably located between two cut portions of the poultry. Optionally, at least one additional axially rotatable cutting element (such as a cutting disc) is partially positioned between the alignment elements to form an incision in the back meat portion adjacent to the spine, preferably a vertical incision (perpendicular to the conveying path), and thus at a distance from and between one or more back meat portions separated by a pre-cut portion. The axis of rotation of the axially rotatable element can be horizontal or slightly inclined. This additional incision is optionally used to divide an outer meat slice into two smaller outer meat slices, which can be separated from the thoracic cavity in a separation section. Preferably, the cutting position of the additional axially rotatable cutting element (the position where the cutting element contacts and cuts the meat) is the lowest position of the rotatable cutting element. Preferably, during operation, the rotational direction of the additional axially rotatable cutting element at the cutting position is opposite to the conveying direction of the poultry, which results in relatively efficient cutting. Thus, in the case where the additional axially rotatable cutting element is used in the alignment section, the alignment section also performs the function of a dividing section. It is conceivable that the additional axially rotatable cutting element is applied and / or positioned at another location along the conveying path without an alignment section, and thus can define a dividing section. Preferably, the dividing section is located upstream of the separation section. Preferably, the splitting section is located downstream of the pre-cut section.
[0018] Preferably, at least one, more preferably each axially rotatable cutting element comprises and / or is formed by an axially rotatable disc, wherein a cutting edge, preferably a circular cutting edge, is provided at the circumferential edge of the disc. The axis of rotation of the axially rotatable disc of the separating part is preferably vertical or inclined with respect to the conveying path, preferably having an inclination angle between 40 degrees and 90 degrees, wherein the cutting position of the rotatable disc is preferably the lowest position of the disc. As described above, the cutting position is the position where the disc contacts and cuts the meat. Preferably, the radius of the disc of the separating part is at least 10 cm, preferably at least 15 cm. This allows the disc to serve as a support surface for the (back) meat separated from the thoracic cavity. This is conceivable and even advantageous in the case where at least part of the upper side of the disc is textured and / or roughened, and / or where the peripheral annular part of the upper side of the disc has a rougher surface than the central part of the upper side of the disc. This results in a relatively high friction at the peripheral part of the disc, which can be used to discharge the cut (back) meat from the cutting disc after separation from the thoracic cavity. Preferably, the upper side of the disc is configured to serve as a support surface for the separated poultry meat and the poultry meat is subsequently removed from the disc due to the centrifugal force exerted by the disc on the poultry meat. The discharged (unloaded) back meat can be received and collected in a storage container.
[0019] The loop conveyor preferably comprises at least one loop belt. The belt can be formed, for example, by a chain. Preferably, the loop belt conveyor comprises an upper run and a lower run, wherein an intermediate space is defined between the upper run and the lower run, and wherein at least a part of the upper run defines the conveying path. Here, the belt conveyor preferably comprises at least one belt return device which facilitates the transfer of the loop belt between the lower run and the upper run. The belt return device preferably comprises at least one guide sprocket, preferably at least one driven guide sprocket and optionally at least one non-driven guide sprocket. A sprocket is generally a toothed or toothless wheel or gear which meshes with and / or co-operates with the belt, such as a chain. Additionally or alternatively, the loop conveyor can be formed by a turntable conveyor, wherein the turntable conveyor preferably also comprises at least one belt, but wherein the belt generally defines a loop track which can be circular or oval or can have any other suitable shape. The belt preferably defines a single plane, which forms a planar conveyor, although a three-dimensional conveyor track is of course also conceivable. In the turntable conveyor, the conveying path can extend through the entire part of the conveyor or through one or more parts of the conveyor.
[0020] The conveyor preferably includes a plurality of poultry carriers, the plurality of poultry carriers being attached to the at least one endless belt, preferably releasably attached to the at least one endless belt. Preferably, at least one poultry carrier, more preferably each poultry carrier, is configured to carry at least one piece of poultry at a distance from the endless belt. This facilitates the processing of the poultry and also reduces unnecessary contamination of the belt. Preferably, at least one poultry carrier, preferably each poultry carrier, includes a base structure mounted to the belt and at least one poultry-carrying structure attached to and standing up from the base structure, wherein the poultry-carrying structure is preferably configured to suspend the poultry onto the carrying structure such that the poultry is positioned at a distance from the base structure. At least a portion of the base structure and the poultry-carrying structure may be integrally connected to each other and may form a single component. At least a portion of the base structure and at least a portion of the assembly of the carrying structure may be formed, for example, from a thermoplastic material, for example by using injection molding. The base structure optionally includes a fixed portion fixed to the belt and a rotating portion rotatably fixed to the fixed portion along a vertical axis and / or an axis perpendicular to the conveying path. This allows the rotating member and the poultry-carrying structure to rotate axially along the conveyor.
[0021] At least one poultry carrier, preferably each poultry carrier, preferably includes at least one insertable body configured to be inserted into the poultry chest cavity. The insertable body preferably forms part of the carrying structure. The insertable body preferably tapers towards the outer end and / or is conical. Preferably, the insertable body points towards its outer end in a direction opposite to the conveying direction of the poultry carrier, at least along (at least a portion of) the conveying path of the conveyor, which conveying path passes through a pre-cut portion and a separating portion. It is generally preferred that the insertable body includes a pair of retaining fingers for engaging with the internal part of the poultry. Here, at least one of the retaining fingers is preferably elastic and / or elastically attached (in particular via a spring strip) to the remainder of the poultry-carrying structure. Preferably, at least two retaining fingers are placed at a mutual distance. The retaining fingers are typically made of metal and / or plastic. Preferably, a portion of the upper side of the insert and / or the upper side of at least one of the retaining fingers is provided with a relief structure, such as a serrated structure, for increasing the grip on the inner side of the poultry.
[0022] Preferably, at least one poultry carrier, preferably each poultry carrier, includes at least one actuatable clamp movable between:
[0023] - a locked position (or fixed position), in which the actuatable clamp is positioned to fix and / or grip a part of the poultry (preferably the internal part of the poultry) relative to the poultry carrier; and
[0024] - Unlocking position (or release position), in which the actuatable clamp is positioned such that the poultry is not fixed and / or released, thereby allowing the unloading of the poultry from the poultry carrier.
[0025] The clamp allows the poultry to be fixed in the respective cutting parts of the device during processing. Preferably, the clamp comprises at least one locking part and an actuating part, the at least one locking part being configured to move between the locking position and the unlocking position, the actuating part preferably being spaced from the locking part, the actuating part being configured to be actuated by the device (in particular a conveyor) to move the locking part between the locking position and the unlocking position. Preferably, the actuatable clamp is pivotally attached to the poultry-carrying structure and preferably extends through the poultry-carrying structure. The clamp is also referred to as a rotary clamp. Preferably, the locking part and the actuating part are located on opposite sides of the poultry-carrying element. Preferably, at least one poultry carrier, more preferably each poultry carrier, comprises at least one latch, in particular an elastic latch, for locking (and / or unlocking) the actuatable clamp in at least one of the locking position or the unlocking position. Preferably, the device is configured such that the actuatable clamp is preferably fixed in the locking position during the transportation of the poultry along an optional preparation part and / or a pre-cutting part and / or an optional alignment part and / or a separation part.
[0026] As described above, it is preferred that at least a part of at least one poultry carrier is rotatable relative to the conveyor, preferably about a rotation axis perpendicular to the conveying path. This allows the poultry to be selectively aligned relative to successive processing sections and optionally aligned in different ways. Preferably, at least a part of at least one poultry carrier is configured to rotate intermittently by the device, in particular the conveyor. Preferably, at least one poultry carrier, preferably each poultry carrier, comprises an axially rotatable base structure mounted to the belt, and at least one poultry-carrying structure attached to and standing up from the base structure, wherein the base structure serves as a driven wheel, in particular a square drive wheel, and wherein the device, in particular the conveyor, comprises at least one drive cam, such as a pin, preferably a fixed pin, which is configured to interact with the driven wheel and thus rotate the driven wheel once the driven wheel passes the drive cam. More preferably, the driven wheel comprises a plurality (n) of slots, where n is preferably 4, the plurality of slots being configured to continuously engage with the drive cam to rotate the base structure (at least a part thereof) by an angle of 360 / n degrees. For example, in the case where the driven wheel comprises 4 slots, the base structure (or at least a part of the base structure) rotates by approximately 90 degrees each time. The driven wheel is preferably a substantially square drive wheel. Preferably, each slot is connected to a corner of the square driven wheel and extends towards the rotation axis of the square driven wheel. Such a configuration comprising a substantially square driven wheel with four slots is also referred to as a Maltese cross drive. Thus, preferably, the device comprises at least one Maltese cross drive to intermittently rotate at least a part of the poultry carrier.
[0027] This rotational possibility of the poultry carrier is preferably used to rotate the poultry carrier upstream of the pre-cutting section such that the poultry (including its spine) is oriented facing in the direction of or opposite to the transport direction. Preferably, the device is configured to rotate the poultry carrier upstream of the preparation section. The preparation section can be used to apply one or more preparation incisions to the thoracic cavity, as will be described in more detail below. The device is preferably configured to rotate the poultry carrier upstream of the loading section and / or upstream of the unloading section to facilitate loading (optionally manually) of the poultry onto the poultry carrier and / or to facilitate unloading of the remaining poultry after removal of the meat (in particular the back meat) in the separation section. The unloading section (if applied) of the device is preferably arranged downstream of the meat separation section and preferably comprises at least one unloading element for removing the remaining poultry parts, in particular the poultry thoracic cavity, from the poultry carrier. The unloading element may comprise at least one scraping element and / or be formed by at least one scraping element, the at least one scraping element preferably being a stationary scraping element, to mechanically remove, in particular slide, the remaining poultry parts, in particular the poultry thoracic cavity, from the poultry carrier. The removed poultry meat parts can be received and collected in a thoracic cavity receiving container.
[0028] As described above, the device preferably comprises at least one preparation part arranged upstream of the pre-cutting part along the conveying path, said preparation part comprising at least one cutting element, preferably a cutting element mounted horizontally, wherein said cutting element is positioned to form at least one incision between the breastbone and the spine of the poultry carried on the poultry carrier. Preferably, the preparation part, in particular its cutting element, is constructed and positioned to cut at least one bone, in particular the coracoid bone, more particularly the left and right coracoid bones, in the vicinity of the spine of the thoracic cavity (carcass). However, if the poultry thoracic cavity includes a collarbone or a carina (commonly referred to as the wishbone) in addition to the coracoid bone, it is conceivable that, in addition to the coracoid bone, the preparation part also cuts said bone. Preferably, the cutting element of the preparation part is a circular cutting element that is axially rotatable, wherein preferably a plurality of grooves and / or teeth are provided along the circumferential edge of the cutting element. The cutting element is preferably rotatable about an axis perpendicular to the conveying path (extending along the preparation part). The preparation part is preferably positioned laterally with respect to the conveyor, and wherein the device is configured to rotate the poultry carrier and / or the poultry carried by the poultry carrier towards the preparation part at least when the poultry carrier passes along the preparation part. By cutting this bone, it is possible to separate any tendons or muscles that the pre-cutting element and / or the separating part cannot (easily) reach. Otherwise, this may result in the back meat not being completely separated, since one or more tendons or muscles in the coracoid bone area may still be intact. This is especially because some tendons and muscles of the (plural) coracoid bones extend inwards towards the inside of the thoracic cavity, and the pre-cutting part cannot easily access this inside without cutting through the entire thoracic cavity, and the latter option is less preferred as this may cause the bone splint to terminate or break the back meat. Some examples of tendons and muscles cut by the preparation part may be the supracoracoideus muscle, however, optionally also a part of the pectoral muscle if attached. This may further and optionally allow the present invention to harvest the back meat of the poultry, including the front half.
[0029] In an embodiment of the device according to the invention, the upstream end of at least one pre-cutting element is narrower than the downstream end. This allows the pre-cutting element to separate the separated (posterior) meat part from the thoracic cavity during displacement along the pre-cutting element, which is beneficial for further processing in, for example, the separating part.
[0030] It is generally advantageous if the device comprises at least one counter-pressure section comprising at least one counter-pressure element, said at least one counter-pressure element being arranged along the conveying path adjacent to and / or overlapping an upstream portion of the pre-cutting element, said upstream portion being arranged on the side of the pre-cutting element facing away from the conveyor. In this case, the at least one counter-pressure element can be formed by a roller and / or a belt. Each roller and / or each belt can have a profiled and / or textured outer surface to improve grip on the passing poultry. It is conceivable that the rollers and / or belts are non-driven. Preferably, each roller and / or each belt is movable and, more preferably, is configured to move with the passing poultry. It is also preferred that the rollers and / or belts are driven, wherein the drive speed is preferably synchronized with the drive speed of the conveyor. Preferably, the conveyor is an endless conveyor having a supply section for supplying the poultry to be processed. This supply section can also be considered a loading section.
[0031] Each driven component can be driven by a drive motor (such as an electric drive motor) of the device. It is conceivable that different components are driven by different drive motors. Additionally or alternatively, it is also conceivable that different components are driven by the same (shared) drive motor. Preferably, the device and / or at least one drive motor is configured to operate continuously.
[0032] The invention also relates to a poultry carrier for use in a device according to the invention.Examples and advantages of the poultry carrier have been described above and will be described in a broad manner below.
[0033] The present invention also relates to a method for removing meat from poultry, in particular for removing poultry back meat from the breast cavity of poultry, in particular by using the device according to the invention, the method comprising the following steps:
[0034] A) loading at least one piece of poultry, in particular a poultry breast with attached poultry back meat, onto at least one poultry carrier,
[0035] B) conveying the loaded poultry carriers along at least a pre-cutting section and a separating section, wherein:
[0036] i. in the pre-cut portion, at least a portion of the poultry meat is partially separated from the rest of the poultry by at least one pre-cutting element, in particular wherein at least a portion of the poultry back meat is partially separated from the poultry breast cavity by at least one pre-cutting element, and wherein
[0037] ii. in the separation section, forming at least one separation cut by at least one rotatable cutting element to separate the at least one pre-cut poultry part from the remaining poultry part, in particular to completely separate the pre-cut poultry back meat from the poultry breast cavity,
[0038] C) removing the separated poultry parts from the remaining poultry parts, in particular removing the separated poultry back meat from the poultry breast cavity, at least in a direction away from the conveying path, wherein the separated poultry parts are preferably unloaded from the device, and
[0039] D) unloading the remaining poultry parts from the poultry carrier.

[0132] Figure 2A detailed view of the preparation section 100 of the device 1 is shown. The figure schematically depicts a first point T1, where the poultry carrier 3 rotates about a vertical axis of rotation 10 of the poultry carrier 3 such that the front side of the meat carrier faces the inward direction of the conveyor 2. The conveyor 2 is formed by a plurality of hooks, to which the poultry carrier 3 is rotatably attached. The T1 of the poultry carrier 3 is arranged upstream of the preparation section 100 and allows the poultry carried on the poultry carrier 3 to be oriented relative to the preparation section 100. The preparation section 100 as shown in this embodiment includes a substantially horizontal cutting element 102. The cutting element 102 is rotatable about a vertical axis of rotation 103 and, as shown in this embodiment, the cutting element 102 is driven by at least one motor 101, in particular an electric motor 101. The cutting element 102 includes a plurality of cutting teeth 104, which contribute to cutting one or more bones of the poultry pieces. In particular, the cutting element 102 is oriented to cut one or more beak bones of a piece of poultry transported by the poultry carrier 3 along the cutting element 102, which is shown in more detail in Figure 3 Before passing through the preparation section 100 of the device, the poultry carrier 3 is transported along the point T2. At this point T2, an actuator 6 is arranged for actuating the actuatable clamp 4 of the poultry carrier. The actuator 6 is arranged to activate the clamping element 4 (also referred to as the actuatable clamp 4) to a clamping position, which can alternatively be referred to as a locking position, for clamping a piece of poultry on the poultry carrier 3. After the clamping element 4 is positioned in the clamping position or the locking position, the poultry piece carried by the poultry carrier 3 can be stabilized to prevent one of the cutting elements of the device from removing or displacing the poultry piece. The actuator 6 shown in this embodiment is a static actuator, which can form part of the frame 8 of the device and is arranged at least stationary relative to the moving conveyor 2. The actuator 6 acts in cooperation with the actuating element 7 of the clamping element 4. The clamping element 4 is pivotally attached to the poultry carrier 3 about a pivot point 5. The actuating element 7 can act in cooperation with the actuator 6 through the guiding action of the actuator 6, gradually forcing the actuating element to pivot the clamping element 4 about the pivot point 5. The poultry carrier 3 preferably includes a locking latch 9 for locking the clamping element 4 in the clamping position. The locking latch 9 can be activated at a predetermined rotation of the clamping element 4.
[0133] Figure 3 shows Figure 2Detailed perspective view of a portion of the preparation section 100 shown in FIG. This figure provides a representation of a piece of poultry 11 carried on a poultry carrier 3. The poultry piece comprises an upper side 11a and a lower side 11b. The upper side 11a typically carries the back meat of the rib cage 11, while the lower side 11b is the side to which the breast is attached. As can be seen, the poultry carrier is shaped so that the upper side 11a of the poultry is carried by the poultry carrier 3 essentially horizontally. This allows for more efficient handling of the poultry 11. In this figure, the clamping element 4 is positioned and locked in the clamping position by the locking latch 9, pressing the poultry 11 against the poultry carrier 3. The cutting element 102 of the preparation section 100 is positioned to cut through the (schematically shown) beak bone 105 of the poultry 11. This allows for (subsequent) removal of the back meat. The cutting element 102 is positioned to cut the beak bone 105 near the spinal column of the poultry 11.
[0134] Figure 4 The subsequent processing steps of the pre-cutting section 200 are shown. Before entering the pre-cutting section 200, the carrier 3 of meat is rotated about the rotation axis 10 in order to orient the piece of poultry in an upstream direction. The poultry carrier 3 is configured to be rotated about its rotation axis 10 by co-acting rotation elements 12, 13. Said co-acting rotation elements 12, 13 allow the poultry carrier to be rotated at a point T3 located just upstream with respect to the pre-cutting section 200. The co-acting rotation elements 12, 13 are formed by a protrusion 12 and a recess 13, wherein at least one of the protrusion 12 or the recess 13 is statically positioned along the conveying path. In the depicted embodiment, the protrusion 12 is arranged along the conveying path so that the poultry carrier 3 moving along said protrusion causes a rotation of the poultry carrier 3. The pre-cutting section 200 comprises at least one cutting element 201, which is arranged for forming an incision in a piece of poultry. The upstream side 202 of the pre-cutting element 201 is essentially non-linear, in particular angled and / or partially curved. Reference will be made to Figure 5The pre-cut incision is described in more detail. To further ensure the precise incision placement of the pre-cut portion 200, the counter-pressure portion 800 is arranged at a distance from the pre-cut portion 200. The counter-pressure portion 800 is arranged to be spaced from the pre-cut element 201 in a direction away from the pre-cut element. The counter-pressure portion 800 is preferably positioned such that it presses at least partially on the poultry carried on the poultry carrier 3. In this particular embodiment, the counter-pressure portion 800 is formed by a driven belt 801, wherein the driven belt 801 is arranged around a pair of drive wheels 803 for driving the driven belt. For this purpose, the drive wheels 803 may include teeth for interacting with the teeth on the inner side of the driven belt 801. Preferably, at least one drive wheel 803 is driven, in particular by a drive motor 804. It is conceivable that the driven belt 801 includes one or more release portions 802. The release portion may be positioned such that at least one release portion 802 is aligned with a part of the poultry carrier 3. Preferably, the release portion 802 is configured to contact the outer side of a part of the back meat of the poultry chest cavity in order to guide and / or align a part of the back meat with the pre-cut portion 200. In the embodiment shown in this figure, a guiding portion 805 is arranged inside the driven belt 801. The guiding portion 805 is formed by a guiding body 806, wherein the guiding body 806 is pivotally attached around a pivot axis 808. A part of the guiding body 806 that is at a certain distance from the pivot axis 808 has elasticity 807 in the direction towards the cutting portion 200. This can ensure that the outer side of the driven belt 801 remains in contact with the poultry back meat at least during transportation through the pre-cut portion 200. It is imaginable that at least one pre-cut element, preferably each pre-cut element, can pivot elastically around a pivot axis 205 that extends substantially parallel to the conveying path. Preferably, the pivot axis 205 is positioned below and / or at a lateral distance from the conveying path with respect to the conveying path. Pivoting the pre-cut element 201 allows for small deviations between poultry pieces to be taken into account. For example, not every chest cavity has the same size. Therefore, in the case where the chest cavity is slightly larger, the pre-cut element 201 can be pushed outwards to accommodate the larger size. Preferably, the pre-cut element has a first maximum position where the pre-cut element is closest to the conveying path, preferably, this position (or further inward rotational movement) is physically or mechanically determined and / or defined. For this purpose, the pre-cut portion 200 may include at least one stop (not visible) for stopping the rotational movement of the pre-cut element 201 in the downward direction. Thus, the stop defines the rest position of the pre-cut element 201. The poultry chest cavity can move the pre-cut element 201 outwards relative to the stop, and when the chest cavity passes the pre-cut element, the pre-cut element elastically returns (e.g., via a spring 206) to the rest position.
[0135] Figure 5Shows a detailed example of the cutting part 200 according to an embodiment of the present invention. The figure further depicts an embodiment of the backpressure part 800 according to the present invention. The backpressure part 800 in this embodiment is formed by a single backpressure roller 809. The roller is positioned to be aligned with the pre-cutting part 200, particularly with the upstream end of the cutting element 201. Different embodiments of the backpressure part 800 can be used interchangeably. In the non-limiting embodiment shown in the figure, the pre-cutting part 200 includes a pair of pre-cutting elements 201, which are positioned at a distance 203 from each other. This distance is preferably greater than about 1 cm, and / or wherein the distance is less than 5 cm. The pair of pre-cutting elements 201 are arranged for cutting in poultry, and the cutting extends at least partially parallel to the transport direction. In this embodiment, the mutually facing edges 204 of the pre-cutting elements 201 are substantially parallel. This allows the poultry block 11 to conveniently pass through the space 203 between the cutting elements 201. Also shown is a schematic cross-sectional view C-C' of the pre-cut poultry block 11. The cross-sectional view of the poultry 11 shows the spine 19 of the poultry, to which the chest cavity 14 is attached. A piece of back meat 15 is (partially) attached to the rear side of the poultry 11. The pre-cutting elements 201 shown in the figure are arranged to each form incisions 17, 18 in the back meat 15. The incisions preferably follow the shape of the chest cavity 14. Since the cutting elements 201 are spaced apart from each other, a part 19 of the back meat remains attached to the poultry 11, particularly to the outer side of the chest cavity 14. The incisions 17, 18 formed by the pre-cutting elements 201 form two remote flaps 20, 21 in the back meat 15.

The figure depicts in sequence from upstream to downstream a pre-cutting part 200, a back-pressure part 800, an alignment part 700, a splitting part 300, and a separating part 400. The details of the pre-cutting part 200 and the back-pressure part 800 as described above apply similarly to this figure. In this embodiment, the separating part 800 is positioned at a distance from the pre-cutting part 200. To provide proper alignment of the meat pieces, the alignment part 700 is arranged between the pre-cutting part 200 and the downstream separating part 400. The alignment part 700 is arranged to be directly adjacent to the pre-cutting part 200 and the separating part 400, and allows the pre-cut poultry parts to be aligned relative to the rotatable cutting element 401 of the separating part 400. In the depicted embodiment, the alignment part 700 includes a pair of alignment elements 705 spaced apart from each other and arranged at a predetermined distance 701 relative to each other.

[0137] A detailed view of a portion of an unloading section 500 according to a non-limiting embodiment of the present invention is shown. Before reaching the unloading section 500, the poultry carriers, particularly the gripping elements 4, need to be released from gripping the poultry, particularly the breast, onto the poultry carriers 3. To this end, the apparatus includes a release element 23 located at point T4 along the transport path, upstream of the unloading section 500. The release element 23 is configured to release the gripping elements 4, displacing them into an unclamped position. To this end, the release element 23 is configured to cooperate with the locking latch 9 of the poultry carrier 3. The release element 23 includes a release surface 24 that is at least partially positioned in the transport path so as to abut against a portion of the locking latch 9. Specifically, the release surface is positioned to rotate the locking latch 9. Rotation of the locking latch 9 causes the protrusion 9A of the locking latch to shift from a locked position, in which the locking latch prevents movement of the gripping elements, to a released position, in which the locking latch allows movement of the gripping elements 4 into an unclamped position. Downstream of the release position T4, an unloading section 500 is arranged. This section removes processed poultry pieces, particularly processed poultry breasts, from the poultry carrier 3. In this embodiment, the unloading section 500 includes at least one scraping element 501 for mechanically removing processed poultry meat parts. The scraping element 501 is a fixed element attached to a portion of the device's frame. Once the processed poultry pieces have been removed by the unloading element or scraping element 501, the poultry carrier can be provided with new poultry pieces to be processed.

In contrast, in the non-clamping position ( ), the distance 26 between the clamping ends of the actuable clamp 4 is positioned further away from the poultry carrier 3 in order to release a piece of poultry. In the clamped position shown, the actuatable clamp 4 is locked by the locking latch 9. In particular, the locking portion 9A of the locking latch 9 is positioned to block the portion 4a of the actuatable clamp 4. In particular, the locking portion 9A prevents the release movement of the portion 4a of the actuatable clamp 4. As can be seen in the unclamped position in FIG. 1 , the locking portion 9A of the locking latch 9 does not prevent the release movement of the portion 4a of the actuable clamp. By pivoting the actuable clamp 4 towards its clamped position (thus from The position shown pivots to ), the locking portion 9A of the locking latch 9 automatically moves in the rotational path of the actuatable clamp 4 so as to prevent a return movement of the actuatable clamp.
[0139] A poultry carrier according to various aspects of the present invention is shown. Although the poultry carrier 3 can be used to transport poultry carcasses in the present invention, it is contemplated that the poultry carrier 3 and aspects thereof can be used independently of the described apparatus. The poultry carrier 3, as shown in this non-limiting embodiment, includes a base structure 3A that is attachable or mountable to a conveyor belt.

The poultry carrier 3, in particular the poultry carrying structure 3B, includes at least one insertable body 36 that can be inserted into the thorax of a poultry. The insertable body 26 is particularly tapered toward one end, in particular toward the outer end. The taper of the insertable body 26 can be substantially similar to the (average) taper of the poultry thorax. To enhance grip on the (inner side) of the poultry's thorax, the insertable body 26 includes a relief structure 27, wherein the relief is applied to the side of the insertable body 26 facing away from the base structure 3A. The relief structure 27 can also be referred to as a serrated structure. Ideally, the relief structure 27 can accommodate one or more ribs of the thorax to partially inhibit thorax slippage. Furthermore, the insertable body 26 can include a pair of retaining fingers 29, 30 for engaging with the inner portion of the poultry. The at least two retaining fingers 29, 30 are positioned at a distance from each other. This allows the cutting element to pass through the retaining fingers during processing of the poultry's thorax. To enhance the functionality of the retaining fingers 29, 30, it has surprisingly been found that making at least one retaining finger resilient and / or resiliently attaching at least one finger to the insertable body 26 significantly enhances grip on the poultry's thorax. In this embodiment, the bottom retaining finger 30 is resiliently attached to the insertable body 26. The resilient mounting member 31 can be formed from a spring blade 31. The poultry carrier may also include at least one actuatable clamp 4, which may also be referred to as a clamping element 4.
