Description

Technical Field

[0001] This invention relates to the field of poultry clavicle trimming equipment, and more specifically to an automatic poultry clavicle trimming device and its trimming method. Background Technology

[0002] Poultry processing companies mostly trim poultry clavicles (such as duck clavicles) and their attached fat and trachea manually. This is not only inefficient and requires a large number of workers, but also increases the risk of hand injuries during large-scale processing, which greatly increases the company's processing costs and poses a very low safety risk. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic poultry clavicle trimming device and its trimming method, which can replace manual labor in separating poultry clavicles from their fat and other attachments. It is highly safe, and can also improve work efficiency and save processing costs.

[0004] The technical solution of the present invention is as follows:

[0005] An automatic clavicle trimming device for poultry is disclosed to replace manual labor in trimming attachments such as fat, trachea, or fascia on the clavicle of poultry (e.g., duck clavicle). The structure of the clavicle is described below. The clavicle includes cartilage, the clavicle body on both sides of its front, and the cartilaginous protrusion in the middle of its back. Usually, there are some fat attachments on the clavicle body on both sides and between the clavicle body and the cartilage. In some clavicles, there are not only fat attachments between the clavicle body and the cartilage on both sides, but also attachments such as trachea or fascia. The trimming device will be described below.

[0006] The trimming device includes a frame and a conveying unit mounted on it, as well as a trimming unit located on the conveying path of the conveying unit. The conveying unit includes a pushing section and a carrying section. A pressing section is correspondingly located above the carrying section. The pushing section is configured to push the clavicle between the carrying section and the pressing section. The carrying section includes a straight carrying section, which includes two carrying members arranged with a gap between them. The trimming unit includes a cutting section rotatably located between the two carrying members. The clavicle bodies on both sides of the clavicle can straddle the two carrying members. The cartilage protrusion of the clavicle faces upward. The cutting section is configured to cut the tracheofascial attachments between the cartilage and the two clavicle bodies, and is also configured to remove the cut tracheofascial attachments. In this process, some grease attachments between the cartilage and the two clavicle bodies can also be removed.

[0007] Furthermore, the material-carrying section also includes a support section parallel to the straight-line bearing section. The support section includes a support plate with an installation opening in the middle. The trimming unit also includes an oiling section located in the installation opening. The oiling section is configured to remove grease attachments from the clavicle. An attachment collection device is provided below the cutting section and the oiling section. The attachment collection device is used to collect the attachments trimmed by the cutting section and the oiling section. The end of the support plate is also provided with a discharge chute. The trimmed clavicle slides from the end of the support plate into the discharge chute under the push of the material-pushing section, thus completing the discharge of the finished product.

[0008] As one implementation method, the oiling section includes a support plate and a second support plate arranged sequentially along the clavicle conveying direction. The oiling section includes two side oiling sections and a middle oiling section respectively located in the mounting openings of the first and second support plates. The two side oiling sections include a separator rod and a first rotating screw assembly on both sides. The two clavicle bodies can enter the two first rotating screw assemblies respectively under the guidance of the separator rod to complete the oiling. The middle oiling section is designed to complete the fine removal of the remaining attachments between the cartilage and the two clavicle bodies.

[0009] Furthermore, the intermediate oiling section includes a second rotating screw assembly arranged along the conveying path. When the clavicle passes through the second rotating screw assembly, the remaining grease attachments between the supraclavicular cartilage and the clavicle body are wiped off.

[0010] The structure and working principle of the first and second rotating screw groups can be the same as those of the screw assembly shown in patent application number CN202221645560.9, and will not be described in detail here.

[0011] To more thoroughly remove the attachments between the cartilage and the clavicle body, the second tray includes an inclined section and a horizontal section arranged sequentially. The first tray is horizontally positioned, and the upper side of the horizontal section of the second tray is flush with the upper side of the first tray. The inclined section of the second tray is inclined upwards towards the conveying direction and is angled and staggered with the second rotating screw assembly. This arrangement ensures that the first end of the second tray is lower than the last end of the first tray, and the first end of the second rotating screw assembly is higher than the upper side of the second tray. This brings the area between the clavicle cartilage and the two sides of the clavicle body closer to the first end of the second rotating screw assembly. This allows the attachments in this area to be removed more precisely and forcefully when passing through the second rotating screw assembly. Because the distance is closer, the friction and compression forces exerted by the second rotating screw assembly on this part of the attachments are stronger, thus removing the attachments more thoroughly.

[0012] The cutting section includes two parallel and spaced-apart cutting blades. The two cutting blades are configured to cut the tracheofascial attachments between the cartilage of the clavicle and the two clavicle bodies by rotating. A material-pushing component is provided between the two cutting blades. The material-pushing component is configured to push off the cut cartilage and the tracheofascial attachments between the two clavicle bodies by rotating.

[0013] The pressing section includes two guide rods with a gap between them. The gap between the two guide rods is adapted to the cartilage protrusion. In use, the two guide rods press down on both sides of the cartilage protrusion on the back of the clavicle, which pushes the clavicle along the support member towards the support plate. On the one hand, pressing down on the clavicle facilitates the trimming unit to perform trimming work, and on the other hand, it provides guidance for the conveying of the clavicle. The gap and height of the two guide rods are adjustable to accommodate clavicles of different specifications.

[0014] To improve equipment adaptability, the guide rod is divided into two sections corresponding to the straight bearing section and the support section, and the height of the two guide rods is adjustable. This allows for flexible adjustment of the two guide rods according to different situations during cutting and oiling, thereby enhancing the equipment's adaptability.

[0015] To reduce equipment space occupation, the material loading section is designed as a horizontally arranged three-section U-shaped structure, which also includes a straight material feeding section parallel to one side of the straight material carrying section, and an arc-shaped reversing section connecting the straight material carrying section and the straight material feeding section. The straight material feeding section includes two material feeding components with gaps and opposite arrangement, which are used for feeding and feeding the clavicle during batch processing. The arc-shaped reversing section includes two reversing components with gaps and opposite arrangement, which are used for reversing when feeding the clavicle. Compared with setting the material loading section as a longer straight section, the structure is more compact and improves space utilization.

[0016] The material pushing section includes a chain / belt drive mechanism horizontally located inside the material carrying section. The chain / belt drive mechanism is provided with several push rods at intervals that can push the clavicle to move. As a preferred implementation method, the chain drive mechanism is selected because its precise chain link cooperation can provide stable thrust, ensuring that the clavicle moves smoothly during the trimming process and reducing clavicle displacement or damage caused by uneven thrust.

[0017] To further improve the stability of the pushing part, a sliding part is provided on the other side of the material loading part relative to the pushing part. The sliding part includes a guide block arranged along the conveying path, on which a guide groove is opened corresponding to the push rod, and the outer end of the push rod slides in cooperation with the guide groove.

[0018] A method for trimming poultry clavicles using the aforementioned automatic trimming device, the method specifically includes the following steps:

[0019] S1: Controls the movements of the feeding section, cutting section, and oiling section;

[0020] S2: Clavicle trimming;

[0021] Specifically, this includes the following two tasks:

[0022] A: Install collarbone;

[0023] The clavicle to be trimmed is placed manually in the material-bearing section, so that the main body of the clavicle on both sides straddles the two bearing members, with the cartilage protrusion facing upward;

[0024] B: The material pushing section pushes the clavicle through the cutting section and the oiling section in sequence for trimming;

[0025] BS2.1 When the pushing part pushes the clavicle to the position of the cutting part, the cutting part starts to work: cuts the tracheofascial attachment connecting the clavicle cartilage and the two sides of the clavicle body, and at the same time removes the cut attachment;

[0026] Finally, the dislodged attachments fell into the attachment collection device;

[0027] BS2.2 When the pushing part pushes the clavicle to the position of the oiling part, the oiling part starts to work: to apply the grease attachments on the clavicle.

[0028] Finally, the removed attachments fell into the attachment collection device;

[0029] Finally, the trimmed clavicle is pushed and moved by the pusher, and finally discharged from the discharge chute.

[0030] The beneficial effects of this invention compared to the prior art are as follows:

[0031] 1. This equipment enables automatic trimming of poultry clavicles, replacing traditional manual operation, reducing the risk of workplace injuries, saving labor costs, and significantly improving production efficiency and safety.

[0032] 2. Through the precise design of the cutting and oiling sections, as well as the coordinated design of the pressing and pushing sections, the equipment can accurately remove grease, air tubes, or fascia from the clavicle, ensuring product quality; 3. The three-section U-shaped structure design of the loading section improves the space utilization of the working area. Attached Figure Description

Detailed Implementation

[0044] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0045] Example

[0046] This embodiment provides an automatic trimming device for poultry clavicles (9), used to replace manual labor in trimming attachments such as fat, trachea, or fascia on poultry clavicles (9, e.g., duck clavicles). The following describes the device in conjunction with... Figure 8 The structure of the clavicle 9 is described below. The clavicle 9 includes cartilage 91, clavicle bodies 92 on both sides of its front part, and cartilaginous protrusions 93 in the middle of its back. Usually, there are some grease attachments on the clavicle bodies 92 on both sides of the clavicle 9 and between the clavicle bodies 92 and the cartilage 91. In some clavicles 9, there are not only grease attachments between the clavicle bodies 92 and the cartilage 91 on both sides, but also attachments such as trachea or fascia. The above-mentioned trimming equipment will be described next.

[0047] Combination Figure 1 and Figure 2The trimming device includes a frame 1 and a conveying unit mounted on it, as well as a trimming unit located on the conveying path of the conveying unit. The conveying unit includes a pushing part 4 and a carrying part 2. A pressing part 3 is correspondingly provided above the carrying part 2. The pushing part 4 is configured to push the clavicle 9 between the carrying part 2 and the pressing part 3. The carrying part 2 includes a straight carrying section, which includes two carrying members 23 arranged with a gap between them. The trimming unit includes a cutting part 5 rotatably located between the two carrying members 23. The clavicle bodies 92 on both sides of the clavicle 9 can straddle the two carrying members 23. The cartilage protrusions 93 of the clavicle 9 face upwards. The cutting part 5 is configured to cut the tracheofascial attachments between the cartilage 91 and the two clavicle bodies 92, and is also configured to remove the cut tracheofascial attachments. In this process, some grease attachments between the cartilage 91 and the two clavicle bodies 92 can also be removed.

[0048] Combination Figure 3 The material loading section 2 also includes a support section parallel to the straight bearing section. The support section includes a support plate with an installation opening in the middle. The trimming unit also includes an oiling section 6 located in the installation opening. The oiling section 6 is configured to remove grease attachments from the clavicle 9. An attachment collection device 7 is located below the cutting section 5 and the oiling section 6. The attachment collection device 7 is used to collect the attachments trimmed by the cutting section 5 and the oiling section 6. The end of the support plate is also provided with a discharge chute 8. The trimmed clavicle 9 slides from the end of the support plate into the discharge chute 8 under the push of the pushing section 4, thus completing the discharge of the finished product.

[0049] Combination Figure 4 To reduce equipment space occupation, the material loading section 2 is configured as a horizontally arranged three-section U-shaped structure, which also includes a straight material feeding section parallel to one side of the straight carrying section, and an arc-shaped reversing section connecting the straight carrying section and the straight material feeding section. The straight material feeding section includes two material feeding members 21 with gaps and opposite arrangement for feeding the clavicle 9 during batch processing. The arc-shaped reversing section includes two reversing members 22 with gaps and opposite arrangement for reversing the material feeding of the clavicle 9. The ends of the two material feeding members 21 are located inside the two reversing members 22, and the beginnings of the two carrying members 23 are connected to the ends of the two reversing members 22, so that the clavicle 9 can be transported smoothly. Compared with setting the material loading section 2 as a longer straight section, the structure is more compact and improves space utilization.

[0050] The material-carrying part 2 is also provided with limiting parts on both sides. Specifically, the limiting parts include a first limiting part 27 which is set opposite to the two straight material members 21 and a second limiting part 28 which is set opposite to the two reversing members 22. The two ends of the two second limiting parts 28 are open in a trumpet shape, and the ends of the two straight material members 21 and the beginnings of the two carrier members 23 are respectively located in the opening. The channel formed between the material-carrying part 2 and the limiting parts provides a conveying space for the clavicle body 92 on both sides of the clavicle 9. On the one hand, it can limit and prevent the clavicle 9 from falling, and on the other hand, it provides guidance for the movement of the clavicle 9. The trumpet-shaped design of the two ends of the second limiting part 28 facilitates the smooth reversal of the clavicle 9.

[0051] For ease of processing and use, the feeder 21, reversing member 22, bearing member 23, first limiting member 27 and first limiting member 27 are all plate-shaped structures.

[0052] The pusher section 4 includes a chain / belt drive mechanism horizontally located inside the loading section 2. The chain / belt drive mechanism is provided with several push rods 42 that can push the clavicle 9 to move. As a preferred implementation, the chain drive mechanism 41 is selected. Due to its precise chain link cooperation, it can provide stable thrust, ensuring that the clavicle 9 moves smoothly during the trimming process and reducing the displacement or damage of the clavicle 9 caused by uneven thrust.

[0053] Specifically, the frame 1 includes a lower frame and an upper frame in the middle of its upper side, both of which are rectangular frame structures. A control box is located in the middle of the upper side of the upper frame, and the control box is electrically connected to the feeding part 4, the cutting part 5, and the oiling part 6. The loading part 2 is horizontally located on the lower frame and outside the upper frame. The lower frame is also equipped with a cutting protective cover located outside the cutting unit to prevent attachments from splashing during cutting. The chain drive mechanism 41 includes sprockets at both ends of the upper frame and a chain wound around the two sprockets. The rotation axis of the two sprockets is vertical, and the plane of the chain is horizontal. The push rod 42 is connected to the chain link through a connecting plate, and the outer end of the push rod 42 passes through the loading part 2 and the pressing part 3.

[0054] To further improve the stability of the pushing part 4, the loading part 2 is also provided with a sliding part on the other side of the pushing part 4. The sliding part includes a guide block 43 arranged along the conveying path, on which a guide groove is opened corresponding to the push rod 42, and the outer end of the push rod 42 slides in cooperation with the guide groove.

[0055] Combination Figure 2 and Figure 3The pressing section 3 includes a turning pressure plate 33 located on the upper side of the arc-shaped reversing section and two guide rods 32 located on the upper side of the cutting unit. The two ends of the turning pressure plate 33 are turned upward and outward to facilitate the smooth passage of the clavicle 9 between the turning pressure plate 33 and the two reversing members 22. The two guide rods 32 are positioned with a gap between them and are mounted on the upper frame through the mounting plate 31. The gap between the two guide rods 32 is adapted to the cartilage protrusion 93. The first ends of the two guide rods 32 are arc-shaped structures with openings facing the outer sides of the ends of the two reversing members 22. During the cutting operation, the two guide rods 32 press down on both sides of the cartilage protrusion 93 on the back of the clavicle 9, which pushes the clavicle 9 along the bearing member 23 towards the support plate for the pushing section 4. On the one hand, pressing down on the clavicle 9 facilitates the trimming unit to perform trimming work, and on the other hand, provides guidance for the conveying of the clavicle 9. The gap and height of the two guide rods 32 are adjustable to accommodate clavicles 9 of different specifications.

[0056] To improve equipment adaptability, the guide rod 32 is provided in two sections corresponding to the straight bearing section and the support section, and the height of the two guide rods 32 is adjustable, so as to flexibly adjust the two guide rods 32 according to different situations during cutting and oiling, thereby enhancing the adaptability of the equipment.

[0057] Combination Figure 5 and Figure 7 The cutting section 5 includes a cutting assembly driven to rotate by a servo motor located on one side of the two support members 23. The cutting assembly includes a columnar cutting seat connected to the servo motor and cutting blades 51 located at both ends of the cutting seat. The two cutting blades 51 are arranged in parallel, and a material-pulling member 52 is also provided on the cutting seat between the two cutting blades 51. The upper side of the two cutting blades 51 protrudes from the support members 23. When the clavicle 9 passes through the cutting assembly, the two cutting blades 51 can cut the tracheofascial attachment between the cartilage 91 of the clavicle 9 and the two clavicle bodies 92 on the two support members 23 by rotation, and the material-pulling member 52 pushes off the cut cartilage 91 and the tracheofascial attachment between the two clavicle bodies 92.

[0058] Combination Figure 7 Two material-pushing components 52 are provided at 180-degree intervals on the outer ring of the cutting seat. The material-pushing components 52 include mounting and material-pushing plates arranged at an angle to each other. The middle part of the mounting plate 31 is connected to the cutting seat. The line connecting the outer end of the material-pushing plate to the rotation center is located on the side opposite to the rotation direction of the line connecting the outer end of the mounting plate 31 to the rotation center. The distance from the outer end of the material-pushing plate to the root of the cutting blade 51 does not exceed 3mm. When the material-pushing plate pushes the cut accessory, the accessory can slide off the outside of the material-pushing plate and the mounting plate 31. The connection between the middle part of the mounting plate 31 and the cutting seat allows the accessory to slide off the outside of the mounting plate 31 to the lower side of the cutting seat without passing through the cutting seat, thereby preventing the accessory from getting tangled on the cutting seat and facilitating the cleaning of the accessory.

[0059] Combination Figure 5 and Figure 6The support plate includes a first support plate 24 and a second support plate 25 arranged sequentially along the conveying direction of the clavicle 9. The oiling part 6 includes two side oiling parts 6 and a middle oiling part 6 respectively provided in the mounting openings of the first support plate 24 and the second support plate 25. The two side oiling parts 6 include a separator rod 61 and a first rotating screw assembly 62 on both sides. The two clavicle bodies 92 can enter the two first rotating screw assemblies 62 respectively under the guidance of the separator rod 61 to complete the oiling. The middle oiling part 6 is designed to complete the fine removal of the remaining attachments or some grease attachments between the cartilage 91 and the two clavicle bodies 92.

[0060] Furthermore, the intermediate oiling section 6 includes a second rotating screw assembly 63 arranged along the conveying path. As the clavicle 9 passes through the second rotating screw assembly 63, the grease attachment between the cartilage 91 and the clavicle body 92 is wiped off.

[0061] The oiling section 6, through the two side oiling sections 6 and the middle oiling section 6, can perform targeted treatment on different areas of the clavicle 9, which can avoid mutual interference between accessories of different parts. The rotation speed and other parameters of the first rotating screw assembly 62 and the second rotating screw assembly 63 can be adjusted separately, thereby achieving more precise cleaning and effectively improving product quality.

[0062] The structure and working principle of the first rotating screw assembly 62 and the second rotating screw assembly 63 can be the same as those of the screw assembly shown in patent application number CN202221645560.9, and will not be described in detail here.

[0063] To more thoroughly remove the attachments between the cartilage 91 and the clavicle body 92, the second tray 25 includes an inclined section 251 and a horizontal section 252 arranged sequentially. The first tray 24 is horizontally arranged, and the upper side of the horizontal section 252 of the second tray 25 is flush with the upper side of the first tray 24. The inclined section 251 of the second tray 25 is inclined upwards and points in the conveying direction, and is arranged at an angle to the second rotating screw assembly 63. This arrangement makes the first end of the second tray 25 lower than the end of the first tray 24, and the first end of the second rotating screw assembly 63 higher than the upper side of the second tray 25. This makes the part between the cartilage 91 of the clavicle 9 and the two clavicle bodies 92 closer to the first end of the second rotating screw assembly 63. This allows the attachments in this part to be removed more accurately and powerfully when passing through the second rotating screw assembly 63. Because the distance is closer, the friction and squeezing force of the second rotating screw assembly 63 on this part of the attachments are stronger, thus removing the attachments more thoroughly.

[0064] Combination Figure 6The supporting section also includes a transition plate 26 located between the carrier 23 and the first support plate 24. The transition plate 26 is inclined upward along the conveying direction, and a notch is provided in the middle of the front side of the transition plate 26. The end of the carrier 23 is located in the notch. When the clavicle 9 passes through, under the action of the transition plate 26, the two clavicle bodies 92 gradually tend to be horizontal from the suspended state on the carrier 23, so that the two clavicle bodies 92 can smoothly enter the first rotating screw for oiling.

[0065] This embodiment also provides a trimming method using the above-described automatic poultry clavicle trimming device, combined with... Figure 1 and Figure 2 In general, the pruning method includes the following steps:

[0066] Step 1: Control the material pushing part 4, the cutting part 5, and the oiling part 6 to start operating;

[0067] Step 2: Collarbone trimming (9th inch), which includes the following two tasks:

[0068] A: Install collarbone 9;

[0069] Single clavicle 9 installation: The clavicle 9 to be trimmed is placed manually on the material carrier 2, so that the clavicle bodies 92 on both sides of the clavicle 9 straddle the two carriers 23, and the cartilage protrusions 93 are facing upwards;

[0070] Batch installation of clavicle 9 (optional): In the case of batch processing of clavicle 9, multiple clavicle 9 can be placed in the material loading section 2 by hand in sequence. During the batch processing, the manual feeding and pushing section 4, the cutting section 5 and the oiling section 6 can be carried out simultaneously.

[0071] The specific operation is as follows: the clavicle body 92 on both sides of the clavicle 9 is inserted into the conveying channel formed between the two straightening members 21 and the two first limiting members 27. At this time, the clavicle 9 straddles the two straightening members 21 with the cartilage protrusion 93 facing upward. Then, in the straddle state, it is pushed along the two straightening members 21 by the push rod 42. After passing between the turning pressure plate 33 and the two reversing members 22, the reversing is completed. Finally, it enters the two bearing members 23, and the cartilage protrusion 93 is located between the two guide rods 32.

[0072] B: The pusher section 4 pushes the clavicle 9 through the cutting section 5 and the oiling section 6 in sequence for trimming;

[0073] Step 2.1 Cutting operation: When the push rod 42 pushes the clavicle to the position of the cutting part 5, the cutting part 5 starts to work: the two cutting blades 51 of the cutting part 5 cut the tracheofascial attachment connecting the cartilage 91 of the clavicle 9 to the two sides of the clavicle body 92, and at the same time the material-pushing part 52 of the cutting part 5 pushes the cut attachment off; finally, the pushed-off attachment falls into the attachment collection device 7.

[0074] Step 2.2, Oiling Operation: When the clavicle 9 passes through the oiling section 6, the oiling section 6 begins to work: the two clavicle bodies 92 are oiled: under the action of the transition plate 26, the clavicle bodies 92 on both sides gradually move from a suspended state on the support member 23 to a horizontal state, so as to smoothly enter the upper side of the first support plate 24. Then, under the guidance of the separator rod 61, the two clavicle bodies 92 respectively enter the two first rotating screw groups 62. The two first rotating screw groups 62 wipe off the grease attachments on the two clavicle bodies 92. Finally, the wiped-off grease attachments fall into the attachment collection device 7.

[0075] Oiling attachments between cartilage 91 and clavicle bodies 92 on both sides (optional): Clavicle 9 continues to move by push rod 42, and clavicle bodies 92 on both sides move along the second support plate 25. The remaining attachments between cartilage 91 and clavicle bodies 92 on both sides will be further wiped off by the second rotating screw assembly 63 and fall into the attachment collection device 7.

[0076] Finally, the trimmed clavicle 9 is pushed by push rod 42 to the discharge chute 8 to complete the discharge; repeat the above feeding, cutting and oiling steps until all clavicles 9 are trimmed.
