Description

Technical Field

[0001] An egg crack detection device belongs to the technical field of egg crack detection. Background Art

[0002] The eggs in the farm need to be cleaned and detected before being packaged. The detection includes a crack detection, that is, checking whether there are cracks in the eggshell. If there are cracks in the eggs, usually these eggs need to be removed from the products as defective or waste products. The existing equipment usually has the following technical problems when in use: 1) When detecting eggs, they are usually conveyed by a conveyor belt. The eggs are placed on the upper side of the conveyor belt and move synchronously with the conveyor belt. This results in that when detecting the cracks of the eggs, it is impossible to ensure all-round detection, and the detection is very inaccurate; 2) The main method for detecting eggs by the existing equipment is lamp inspection. Whether there are cracks on the egg surface is detected through image comparison technology. The detection efficiency is low, and there will be a problem that the patterns or foreign matters on the egg surface are easily misjudged as cracks by the lamp inspection system.

[0004] The technical solution adopted by the present invention to solve its technical problems is: The egg crack detection device is characterized in that: it includes a detection device, an egg conveying mechanism and a rejection device. The detection device and the rejection device are arranged in sequence along the egg conveying direction. The tops of the detection device and the rejection device are both provided with guiding parts for guiding the eggs. The egg conveying mechanism is arranged on the upper side of the guiding parts and pushes the eggs to roll on the guiding parts.

[0005] Preferably, the detection device includes a detection seat body and piezoelectric sensors. A detection channel is arranged at the top of the detection seat body, and a plurality of the piezoelectric sensors are arranged side by side along the length direction below the detection channel.

[0006] Preferably, the detection channel includes a first detection channel and a second detection channel. The first detection channel and the second detection channel are parallel and staggered. A plurality of the piezoelectric sensors are respectively arranged side by side along the length direction below the first detection channel and the second detection channel. A horizontally arranged first guiding plate is arranged on one side of the first detection channel, and a horizontally arranged second guiding plate is arranged on one side of the second detection channel. The first guiding plate and the first guiding vertical plate are respectively arranged on both sides of the detection seat body. The egg conveying mechanism pushes the eggs to roll through the first detection channel and the second detection channel in sequence.

[0007] Preferably, a first guiding vertical plate is provided on the other side of the first detection channel, and a second guiding vertical plate is provided on the other side of the second detection channel.

[0008] Preferably, a sealing cover is provided on the upper side of the detection seat body. A plurality of detection holes corresponding to the piezoelectric sensors are formed in the sealing cover. The detection holes are located in the middle of the detection channels. The piezoelectric sensors are arranged on the lower side of the sealing cover, and the upper ends of the piezoelectric sensors extend into the detection holes or are arranged on the lower sides of the detection holes.

[0009] Preferably, an output track is further included. The rejection device includes a movable track and a sorting track. The movable track is slidably connected to the output end of the sorting track. The movable track is connected with a power device that drives it to move in a direction close to or away from the sorting track. The output track is arranged at the output end of the movable track.

[0010] Preferably, mounting plates are symmetrically arranged on both sides of the movable track. The upper parts of the mounting plates on both sides are arranged at intervals to form the sorting track. The movable track is slidably connected to the mounting plates.

[0011] Preferably, guide columns are arranged on the movable track, and elongated guide holes are arranged on the mounting plates. The guide columns are slidably arranged in the corresponding elongated guide holes on the corresponding side.

[0012] Preferably, an input track is further included and is arranged at the input end of the detection device. At least two input guiding plates are arranged side by side at the input end of the detection device. The input track is arranged between the two input guiding plates.

[0013] Preferably, a concave relief opening is arranged on the side of the output end of each input guiding plate away from the input track.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The egg conveying mechanism of the present egg crack detection device pushes the eggs to roll on the guiding part, ensuring that the detection device can perform a full-range detection on the eggs, ensuring comprehensive detection, solving the problem that cracks on the lower side cannot be detected due to the occlusion of the conveyor belt, completely removing the cracked eggs, and having high working accuracy.

[0016] 2. The egg conveying mechanism is used to push the eggs to roll through the detection channel. When an egg collides with the piezoelectric sensor, vibrations will be generated. The inventor found that the vibration frequencies of eggs with or without cracks on the surface are different during the rolling process. When there are cracks on the eggshell, the vibration frequency of the egg is lower. The controller records the number of contacts between the egg and each egg detection unit, that is, the vibration frequency of the egg. The controller sets a vibration range. When the vibration frequency of the egg falls within the vibration range set by the controller, it indicates that there are cracks on the egg surface, and the egg is thus removed. By detecting the frequency to find out whether there are cracks on the egg surface, it can avoid the influence of dirt on the egg surface on the detection accuracy. The detection of the present invention is more accurate, with high detection efficiency, and the detection device has a compact structure and a smaller equipment volume.

[0017] 3. The first detection channel and the second detection channel are arranged in parallel and staggered. A plurality of piezoelectric sensors are arranged side by side along the length direction on the lower sides of the first detection channel and the second detection channel respectively, which can detect cracks from both ends of the egg respectively. With the rolling of the egg, it can ensure more accurate and comprehensive egg detection results.

[0018] 4. The first guiding vertical plate and the second guiding vertical plate can not only play a guiding role for the eggs, but also play a protective role for the eggs to prevent the eggs from falling off the detection channel.

[0019] 5. The movable track can move along the direction close to or away from the sorting track with the power device. The sorting track is docked with the output track through the movable track. When the detection device detects that the egg has cracks, the power device drives the movable track to move towards the sorting track, so that a space for the egg to fall is formed between the movable track and the output track. The cracked eggs fall from between the output track and the movable track, and then the power device drives the movable track to reset and guides the intact eggs onto the output track, realizing the automatic detection of egg cracks and the automatic sorting of the cracked eggs. It has high working efficiency, and the whole process is automated, which can not only meet the speed requirements of the production line but also will not damage the eggs.

[0020] 6. The mounting plates on both sides can not only form the sorting track to guide the eggs, but also facilitate the docking with the movable track, and the movement of the movable track will not affect the conveyance of eggs between it and the sorting track.

[0021] 7. The movable track is guided by the guiding columns and guiding long holes, with good guiding effect, and the installation of the movable track can also be realized.

[0022] 8. The input track is arranged between two input guiding plates. Eggs are guided by the input track, and the egg conveying mechanism pushes the eggs to move along the input track. The two ends of the eggs are placed on the input guiding plates on both sides, and are smoothly docked with the detection device. When the eggs enter the detection device from the input track, they will not jump, preventing the eggs from falling off the track and causing no damage to the eggs, ensuring the stable operation of the system.

[0023] 9. A relief opening is provided on the side of the output end of each input guiding plate away from the input track, facilitating docking with the detection device and preventing the excessive width of the input guiding plate from affecting the docking with the input end of the detection device.

Detailed Implementation Manner

[0033] Figures 1 to 8 is the best embodiment of the present invention, and the present invention will be further described below with reference to the attached Figures 1 to 8 drawings.

[0034] An egg crack detection device includes a detection device, an egg conveying mechanism, and a rejection device. The detection device and the rejection device are arranged in sequence along the egg conveying direction. Guide parts for guiding eggs are provided on the tops of the detection device and the rejection device. The egg conveying mechanism is arranged above the guide parts and pushes the eggs to roll on the guide parts. The egg conveying mechanism of this egg crack detection device pushes the eggs to roll on the guide parts, ensuring that the detection device can perform a full-range detection of the eggs, ensuring comprehensive detection, solving the problem that cracks on the lower side cannot be detected due to the occlusion of the conveyor belt, completely rejecting cracked eggs, and having high working accuracy.

[0035] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0036] As Figure 1 shown: This egg crack detection device further includes an input track 14, a transition track 27, and an output track 18. The input track 14 is arranged at the input end of the detection device. The transition track 27 is arranged between the detection device and the rejection device. The output track is arranged at the output end of the rejection device. A receiving device is arranged below the rejection device, and the receiving device is used to receive the rejected eggs.

[0037] As Figures 2 to 4 shown: The detection device includes a detection base 1, an egg conveying mechanism, and a piezoelectric sensor 10. An egg conveying mechanism is provided on the upper side of the detection base 1. The egg conveying mechanism pushes the eggs to roll along the detection channel 15. A plurality of the piezoelectric sensors 10 are arranged side by side along the length direction below the detection channel 15.

[0038] The detection channel 15 includes a first detection channel 6 and a second detection channel 8. The first detection channel 6 and the second detection channel 8 are arranged in parallel and staggered. A plurality of the piezoelectric sensors 10 are provided side by side along the length direction on the lower sides of the first detection channel 6 and the second detection channel 8 respectively. A first guiding flat plate 4 is horizontally provided on one side of the first detection channel 6, and a second guiding flat plate 5 is horizontally provided on one side of the second detection channel 8. The first guiding flat plate 4 and the first guiding vertical plate 2 are respectively arranged on both sides of the detection seat body 1. The egg conveying mechanism pushes the eggs to roll through the first detection channel 6 and the second detection channel 8 in sequence. When the eggs roll in the detection channel 15, one end of the egg lands on the guiding flat plate, which can cause the egg to tilt to a certain extent, so that the piezoelectric sensors 10 on the lower side of the detection channel 15 can detect the eggs. When the eggs roll through the first detection channel 6 and the second detection channel 8, all detections of both ends of the eggs can be completed. Moreover, due to the certain tilt of the eggs, the cracks at the egg ends can also be detected, and the detection accuracy is higher.

[0039] A first guiding vertical plate 2 is provided on the other side of the first detection channel 6, and a second guiding vertical plate 3 is provided on the other side of the second detection channel 8. The first guiding vertical plate 2 and the second guiding flat plate 5 are integrally and fixedly connected to one side of the detection seat body 1, and the second guiding vertical plate 3 and the first guiding flat plate 4 are integrally and fixedly connected to the other side of the detection seat body 1. When the eggs roll in the detection channel 15, one end of the egg lands on the guiding flat plate, and the other end is positioned by the guiding vertical plate to ensure that the eggs roll stably along the detection channel 15.

[0040] A sealing cover 9 is provided on the upper side of the detection seat body 1. A plurality of detection holes 7 corresponding to the piezoelectric sensors 10 are provided on the sealing cover 9. The detection holes 7 are located in the middle of the detection channel 15. The piezoelectric sensors 10 are arranged in the detection seat body 1, and the upper ends of the piezoelectric sensors 10 extend into the detection holes 7 or are arranged below the detection holes 7. The sealing cover 9 can prevent the egg liquid of the damaged eggs from falling into the detection device. Once the egg liquid enters the inside of the detection device, it is very difficult to clean. Moreover, if it is not discovered in time, the egg liquid will deteriorate and produce a strange smell. In this embodiment, the sealing cover 9 is used to isolate the egg liquid, which is convenient for discovery and cleaning. In this embodiment, it is preferably that the sealing cover 9 is made of plastic material and has a certain elasticity. After the egg lands on the sealing cover 9, the sealing cover 9 is pressed down and contacts the piezoelectric sensor 10. For more accurate detection, a detection head is provided on the upper side of the piezoelectric sensor 10, and the detection head extends upward out of the sealing cover 9 when the egg presses down the sealing cover 9.

[0041] As Figures 5 to 6As shown in the figure: The egg conveying mechanism includes an egg-pushing chain 11 and egg-pushing rollers 12. The two egg-pushing chains 11 are arranged on both sides of the detection base 1, and a plurality of the egg-pushing rollers 12 are evenly connected between the two egg-pushing chains 11. The egg-pushing chain 11 drives the egg-pushing rollers 12 to move, and the egg-pushing rollers 12 push the eggs on the detection base 1 to roll, so as to comprehensively detect the eggs. In order to ensure the stable operation of the egg-pushing chain 11, a tensioning wheel 13 is connected to the egg-pushing chain 11 in this embodiment. In order to improve the detection efficiency, a plurality of detection bases 1 are arranged side by side. The egg-pushing rollers 12 can simultaneously push the eggs on a plurality of detection bases 1 to roll, and the structure is simpler and more compact. Horizontal support rods 19 are arranged on the lower sides of the upper and lower parts of each egg-pushing chain 11 to assist the egg-pushing chain 11 in bearing the weight of the egg-pushing rollers 12.

[0042] Working process: The egg-pushing chain 11 drives the egg-pushing rollers 12 to move, and the egg-pushing rollers 12 push the eggs on the detection base 1 to roll. First, the eggs enter the first detection channel 6, and the eggs fall between the first guiding flat plate 4 and the first guiding vertical plate 2. Then the egg-pushing rollers 12 continue to push the eggs into the second detection channel 8, and the eggs fall between the second guiding flat plate 5 and the second guiding vertical plate 3. The controller records the number of contacts between the eggs and each piezoelectric sensor 10, that is, the vibration frequency of the eggs. The controller sets a vibration range. When the vibration frequency of the eggs falls within the vibration range set by the controller, it indicates that there are cracks on the surface of the eggs, and the eggs are thus removed. By detecting the frequency, it can be found whether there are cracks on the surface of the eggs, which can avoid the influence of dirt on the surface of the eggs on the detection accuracy. The detection of the present invention is more accurate, has a high detection efficiency, and the detection device has a compact structure and a smaller equipment volume. During the rolling process of the eggs, through a plurality of piezoelectric sensors 10, it can accurately detect whether there are cracks on all surfaces of the eggs, and the detection is more accurate and reliable.

[0043] As Figures 7 to 8 shown: Every two input guiding plates 26 form a group, and the two input guiding plates 26 in each group are arranged at intervals to form an input track 14 for guiding eggs. A plurality of groups of input guiding plates 26 are arranged side by side to guide a plurality of eggs simultaneously. In this embodiment, six groups of input guiding plates 26 are arranged side by side to form six input tracks 14. The input tracks 14 correspond to the detection channels 15 one by one.

[0044] The input guiding plates 26 are inclined with the output end higher than the input end, and the distance between the two input guiding plates 26 in each group is 80 - 104 mm. A square relief opening is arranged on the side of the output end of each input guiding plate 26 away from the input track 14, so as to facilitate the docking with the input end of the detection device, avoid the excessive width of the input guiding plate 26 affecting the docking with the detection device, and also avoid the too small width of the input guiding plate 26, affecting its strength and causing the eggs to easily slide off the input track 14.

[0045] The movable track 23 is slidably connected to the output end of the sorting track 17, and the movable track 23 is connected with a power device that drives it to move in a direction close to or away from the sorting track 17. The movable track 23 can move along a direction close to or away from the sorting track 17 with the power device. The sorting track 17 is docked with the output track 18 through the movable track 23. When the detection device detects that the egg has a crack, the power device drives the movable track 23 to move towards the sorting track 17, so as to form a space for the egg to fall between the movable track 23 and the output track 18. The cracked egg falls between the output track 18 and the movable track 23, and then the power device drives the movable track 23 to reset and guides the intact egg onto the output track 18, realizing the automatic detection of egg cracks and automatically sorting out the cracked eggs, with high working efficiency. The whole process realizes automation, which can not only meet the speed requirements of the production line but also will not damage the eggs.

[0046] A transition track 27 is arranged between the input end of the sorting track 17 and the detection channel 15, which facilitates the docking between the sorting track 17 and the detection channel 15 and avoids the problem that the eggs are likely to fall off due to the over-width of the sorting track 17. A plurality of transition guide plates 21 are arranged side by side at the output end of the detection channel 15. Each adjacent two transition guide plates 21 are arranged at intervals to form a transition track 27. The transition track 27 cooperates with the egg roller 12 to send out the intact eggs. The transition track 27 corresponds to the detection channel 15 one by one, and the sorting track 17 corresponds to the transition track 27 one by one. The transition track 27 is in an inclined shape with the output end higher than the input end, ensuring that the eggs roll reversely and stay in front of the corresponding egg roller 12 under the power-off state, avoiding the free forward transportation of the eggs and facilitating the precise control of the egg transportation. The input track 14 and the detection channel 15 are also in an inclined shape with the output end higher than the input end, and the lower part of the egg-pushing chain 11 is also in an inclined shape that gradually rises along the egg transportation direction.

[0047] An arc-shaped guiding part 2301 with a concave middle part is arranged on the upper part of the movable track 23. The guiding part 2301 can guide the eggs to avoid the eggs rolling off the movable track 23. The movable track 23 corresponds to the sorting track 17 one by one. Each movable track 23 is connected with a power device, and the power device is a cylinder 24 or an electric push rod. In this embodiment, the power device is a cylinder 24. The piston rod of the cylinder 24 is connected to the movable track 23 and pushes it to reciprocate along the egg transportation direction.

[0048] On both sides of the movable track 23, mounting plates 22 are symmetrically arranged, and a sorting track 17 is formed between the two mounting plates 22. The top of the movable track 23 is flush with the top of the mounting plate 22. The movable track 23 corresponds to the mounting plate 22 one by one, and the movable track 23 also corresponds to the detection channel 15 one by one. The cylinder 24 is arranged between the corresponding two mounting plates 22. The cylinder 24 is connected to the mounting plate 22 through a mounting member 25. Both sides of the mounting member 25 are fixedly connected to the corresponding side of the mounting plate 22. The cylinder 24 is hinged to the middle of the mounting member 25. The piston rod of the cylinder 24 is connected to the movable track 23 and pushes it to translate. Both the sorting track 17 and the movable track 23 are inclined with the output end higher than the input end, ensuring that the eggs roll backward under power-off conditions and stay in front of the corresponding egg roller 12, preventing the eggs from being freely conveyed forward and facilitating the precise control of the egg conveyance.

[0049] A guiding mechanism is arranged between the movable track 23 and the corresponding side of the mounting plate 22. The guiding mechanism includes a guiding column 2302 arranged on the movable track 23 and a guiding long hole 2201 arranged on the mounting plate 22. Two guiding columns 2302 are arranged at intervals on each side of the movable track 23, and both guiding columns 2302 are horizontally arranged along the direction parallel to the egg conveyance. The guiding long hole 2201 is also horizontally arranged along the direction of egg conveyance. The two guiding columns 2302 on the same side of the movable track 23 are both slidably arranged in the corresponding guiding long hole 2201. This not only completes the installation of the movable track 23 but also can guide the movement of the movable track 23, ensuring that the movable track 23 is always docked with the corresponding sorting track 17.

[0050] On both sides of each sorting track 17, protective plates 28 are symmetrically arranged. The upper part of the protective plate 28 is higher than the sorting track 17. The protective plate 28 is in an inclined shape that gradually approaches the sorting track 17 from top to bottom. This not only facilitates the installation of the protective plate 28 but also ensures that the upper spacing of the protective plate 28 is sufficient to avoid interfering with the egg conveyance. The protective plate 28 can prevent the eggs from falling off the sorting track 17 during the conveyance process. The output track 18 is arranged at the output end of the movable track 23 and corresponds to the movable track 23 one by one, thereby sending out the intact eggs.

[0051] The receiving device includes a brush roller 16 and a receiving motor. Multiple pairs of brush rollers 16 are arranged at intervals from top to bottom. Each pair of brush rollers 16 includes two that are parallel and spaced apart on a horizontal plane. In this embodiment, only one pair of brush rollers 16 is provided. The brush roller 16 is connected to the receiving motor and moves synchronously with the receiving motor. The two brush rollers 16 of the same pair are connected by a transmission belt or gears, thereby realizing synchronous rotation in opposite directions and conveying the received eggs downward to prevent the eggs from being damaged. A conveyor belt is arranged below the receiving device to send out the eggs with cracks.

[0052] As described above, it is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
