A planar two-way synchronous transfer system for grading poultry eggs

Abstract

This invention relates to a planar two-way synchronous transfer system for grading poultry eggs. Located between a slow-speed conveyor line and a fast-speed conveyor line, the system achieves synchronous operation with the two conveyor lines, which move perpendicularly to each other and at different speeds, within one transfer cycle. During egg receiving, it operates synchronously with the slow-speed conveyor line at the same speed; during egg placement, it operates synchronously with the fast-speed conveyor line at the same speed, ensuring damage-free egg transfer. This invention achieves synchronous transfer of poultry eggs on two conveyor lines with unequal speeds and perpendicular directions—that is, synchronous operation with the slow-speed conveyor line during egg receiving and synchronous operation with the fast-speed conveyor line during egg placement—ensuring damage-free egg transfer. Compared to a lifting arm, it reduces wear on mechanical components and improves the stability of egg transfer. The drive mechanism adopts a purely mechanical structure, is compact, and has a low failure rate.

Description

Technical Field

[0001] This invention relates to the field of poultry egg primary processing technology, and more specifically to a planar two-way synchronous transfer system for grading poultry eggs. Background Technology

[0002] my country started relatively late in the field of poultry egg primary processing equipment manufacturing, but with the development in recent years, some achievements have been made in this field. For example, patent document CN111846352A discloses a new type of transitional conveying device for poultry egg grading and packaging. This technology was used to mass-produce an integrated poultry egg grading and packaging machine in the same year. The main technical goal of this equipment is to transfer eggs from the slow six-channel conveyor to a single-row fast conveyor line. Because the speed of the single-row fast conveyor line can only reach 30,000 eggs / hour at most, the production capacity of the equipment mass-produced in 2020 was only 30,000 eggs / hour.

[0003] In recent years, the scale of egg-laying hen farming in China has been expanding continuously, and the level of large-scale and intensive egg-laying hen farming has been increasing. Equipment with a capacity of 30,000 eggs per hour can no longer meet the demand. At present, China is completely lacking in technology for higher-capacity poultry egg grading equipment.

[0004] To further increase the equipment capacity from 30,000 eggs / hour, the current mainstream international solutions involve increasing the number of rows in the high-speed conveyor line. A single row of high-speed lines can reach 30,000 eggs / hour, two rows can reach 60,000 eggs / hour, and four rows can reach 120,000 eggs / hour. Simultaneously, this can be achieved by increasing the number of rows in the slow-speed feed section or increasing the operating speed of the slow-speed feed. For example, in existing technologies, the eggs are grouped into sets of three, and a lifting arm is used to lift each group of eggs in a staggered order and feed them into multiple rows of high-speed conveyors.

[0005] The above solution has the following problems:

[0006] 1. The slow conveyor line is equipped with multiple rows and columns of lifting arms. Each lifting arm is connected at a 45-degree angle. The lifting action of the lifting arm relies on the irregular groove guide rail. Due to repeated lifting, the irregular groove guide rail is prone to wear.

[0007] 2. During the rotation and lifting process of the lifting arm, the speed in the slow movement direction is offset by a 45-degree angle, while maintaining synchronization with the fast conveyor line. One lifting action needs to complete synchronization in two directions, which is complex. Due to the short synchronization time, the stability is poor, and the breakage rate of poultry eggs is high during transportation.

[0008] 3. The eggs are lying flat on the support arm without being forcibly secured, posing a risk of falling off and further increasing the breakage rate.

[0009] Therefore, how to provide a planar two-way synchronous transfer system for grading poultry eggs is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0010] Therefore, one objective of this invention is to propose a planar two-way synchronous transfer system for grading poultry eggs, thereby solving the technical problem of high breakage rate in existing poultry egg grading devices during the transfer of poultry eggs.

Within one transfer cycle, it achieves synchronous operation with the two conveyor lines that are perpendicular to each other and have different speeds. During the egg receiving process, it runs synchronously with the slow conveyor line at the same speed, and during the egg release process, it runs synchronously with the fast conveyor line at the same speed, ensuring the transfer of poultry eggs without damage.

[0031] The drive linkage assembly includes two independent planar four-bar linkages: a fast synchronous drive assembly connected to the fast conveyor line and a slow synchronous drive assembly connected to the slow conveyor line. The fast synchronous drive assembly is connected to the fast synchronous cam, and the slow synchronous cam is connected to the slow synchronous drive assembly.

[0032] The driver drives the camshaft to rotate, which in turn drives the fast synchronizing cam and the slow synchronizing cam to rotate.

[0033] Furthermore, the fast synchronizing cam has an annular first mounting groove on its inner side, and the slow synchronizing cam has an annular second mounting groove on its inner side. The first mounting groove is connected to the fast synchronizing drive assembly, and the second mounting groove is connected to the slow synchronizing drive assembly.

[0034] The fast synchronization drive components include:

[0035] A fast synchronous drive swing arm has a first connection point at its top and a second connection point at its bottom, on which an active swing arm positioning shaft is connected. A bearing pin is located in the middle of its outer side, and this bearing pin is inserted into a first mounting groove, on which a fast cam bearing is mounted.

[0036] A quick-synchronizing link is connected to one end of the quick-synchronizing link at the first connection point;

[0042] The fast passive swing arm fixing rod is connected to the fast conveyor line; the connecting pin is connected to the slow conveyor line.

[0043] Furthermore, the synchronous transfer device includes:

[0044] The transfer base plate assembly includes a rectangular base plate fixed on the frame. Four longitudinally arranged guide rails 1 are fixed at the four corners of the rectangular base plate. Two guide rails 2 are arranged horizontally within the area enclosed by the four guide rails 1. A guide rail 3 is arranged parallel to the edge of the rectangular base plate and the guide rails 2. The length of the guide rail 3 is greater than the length of the guide rail 2, and the length of the guide rail 2 is greater than the length of the guide rail 1.

[0050] The egg-catching opening and closing guide rail consists of four rails located at the four corners of the slow-speed frame and fixed by guide rail fixing plates. When the egg-catching device releases the eggs, the guide rails apply a pushing force to the egg-catching device.

The bottom of each set of slider joints has a slow synchronous slider that slides with the guide rail, and the top has a slanted drive block with a slanted groove. The two sets of slider joints are connected by a synchronous drive connecting rod. One end of the assembly has a drive pin that connects to the slow drive connecting rod in the drive mechanism.

The outside of one side of the long frame has a sliding cylindrical sleeve through which one end of the egg-catching drive connecting rod passes. The short frame near the drive end has a pin lug that connects to the fast drive connecting rod.

[0054] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows:

[0055] 1. In the process of transferring poultry eggs, the present invention ensures that the poultry eggs move synchronously with the conveyor line in both directions. That is, during the egg receiving process, the eggs move synchronously and at the same speed as the slow conveyor line, and during the egg releasing process, the eggs move synchronously and at the same speed as the fast conveyor line, thus ensuring the transfer of poultry eggs without damage.

[0056] 2. This invention employs an egg-receiving device, a drive mechanism, and a synchronous transfer device. During egg transfer, the drive mechanism and the synchronous transfer device work together. The drive mechanism includes two independent planar four-bar linkages. Driven by fast and slow synchronous cams, it can perfectly match the fast and slow conveyor lines, completing synchronous egg transfer in both directions, thus improving production capacity. Compared to a lifting arm, it reduces wear on mechanical components and improves the stability of egg transfer. The drive mechanism adopts a purely mechanical structure, is compact, and has a low failure rate.

[0057] 3. This invention features at least two rows of egg-catching mechanisms connected within the same egg-catching frame assembly. The structure is compact with a small center distance, allowing it to match the spacing between the double rows of eggs on both fast and slow conveyor lines. The egg-catching frame assembly has a frame-like structure, ensuring structural stability during operation and reducing the risk of egg breakage. The opening of the egg-catching space relies on external force to drive the egg-catching frame assembly, while closing relies on an elastic tensioning part, satisfying the opening and closing control of at least two rows of egg-catching mechanisms.

[0058] 4. In use, the egg-receiving mechanism of the present invention is in the egg-receiving state when it runs in the same direction and speed as the slow conveyor line, and in the release state when it runs in the same direction and speed as the fast conveyor line. It is supported at both ends, so the structure is stable and the eggs always remain vertical during the transfer, with no risk of falling off. Attached Figure Description

[0089] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0090] In existing technologies for weight-based grading and conveying of poultry eggs, multiple rows and columns of lifting arms are arranged on the slow conveyor line, with each arm connected at a 45-degree angle. The lifting action of the lifting arms relies on irregularly shaped chute guide rails, which are prone to wear due to repeated lifting. During the rotation and lifting process of the lifting arms, the 45-degree angle counteracts the speed in the slow movement direction while maintaining synchronization with the fast conveyor line. A single lifting action requires synchronization in two directions, resulting in a complex structure. Due to the short synchronization time and poor stability, the breakage rate of poultry eggs is high during transportation. Furthermore, the eggs lie flat on the lifting arms without being forcibly secured, posing a risk of falling and further increasing the breakage rate.

[0091] In view of this, see Appendix Figure 1This invention discloses a planar two-way synchronous transfer system 162 for grading poultry eggs. It is located between a slow conveyor line 161 and a fast conveyor line 163. Within one transfer cycle, it achieves synchronous operation with the two conveyor lines that are perpendicular to each other and have different speeds. During the egg receiving process, it is synchronized with the slow conveyor line at the same speed, and during the egg release process, it is synchronized with the fast conveyor line at the same speed, ensuring the transfer of poultry eggs without damage.

[0092] In the above scheme, the slow conveyor line 161 is located at the top, the planar two-way synchronous transfer system 162 is in the middle, and the fast conveyor line 163 is at the bottom.

[0093] Direction of movement: The slow conveyor line 161 and the fast conveyor line 163 move in a perpendicular direction.

[0094] Movement speed: For example, slow conveyor line 161 has 12 rows of conveyors at a constant speed, while fast conveyor line 163 has 2 rows of conveyors. Therefore, under the same production capacity, the speed of fast conveyor line 163 is 6 times that of slow conveyor line 161.

[0095] The planar two-way synchronous transfer system in this invention is a movement method in which poultry eggs are transferred from the slow conveyor line 161 to the fast conveyor line 163.

[0096] The slow conveyor 161 moves along the first direction 164, and eggs fall from the slow conveyor 161 at fixed positions, with at least two rows falling at a time. The planar two-way synchronous transfer system 162 is located below the slow conveyor 161, and the fast conveyor 163 moves along the second direction 165.

[0097] In the above scheme, during the transfer of poultry eggs, the eggs and the conveyor line move in the same direction. That is, during the egg receiving process, the eggs move synchronously and at the same speed as the slow conveyor line, and during the egg releasing process, the eggs move synchronously and at the same speed as the fast conveyor line, ensuring the transfer of poultry eggs without damage.

[0098] The above-described solution of the present invention is described in the appendix. Figure 2 At least including:

[0099] Egg receiving device 153 is used to receive and release eggs during the transfer of poultry eggs; it has at least two rows of egg-carrying spaces.

[0100] Drive mechanism 151 provides power during the transfer of poultry eggs;

[0101] The synchronous transfer device 152 and the egg receiving device 153 are installed inside the synchronous transfer device 152 and cooperate with the drive mechanism 151 to achieve synchronous operation with the slow conveyor line 161 or synchronous operation with the fast conveyor line 163.

[0102] Figure 2The components include a drive mechanism 151, a synchronous transfer device 152, an egg receiving device 153, a fast drive connecting rod 154, a slow drive connecting rod 155, and an egg receiving drive connecting rod 156.

[0103] The egg-receiving device 153 reciprocates along two directions, 157 and 158, on a single plane. During egg collection and placement, the speed of the eggs is synchronized with the speed of the conveyor line; therefore, this system is called a two-way synchronous transfer system. The first direction 164 is the same as direction 157, and the second direction 165 is the same as direction 158.

[0104] The above plan is detailed in the appendix. Figure 3 The egg-collecting device 153 includes an egg-collecting process, an egg-releasing process, and a return process during the transfer of poultry eggs; in these three processes, the displacement trajectory of the egg-collecting device is a right-angled triangle. That is, within one operating cycle, the operating trajectory of the egg-collecting device 153 is as follows: Figure 3 As shown, segment AB is the egg-receiving process, segment BC is the egg-releasing process, and segment CA is the return process.

[0105] In one embodiment of the present invention, the appendix Figure 4 In the middle, 41 is the left egg-catching component, 42 is the right egg-catching component, 43 is the egg-catching frame component, and 44 is the elastic tensioning part.

[0106] The egg-collecting device 153 includes at least two rows of egg-collecting mechanisms. Each row of egg-collecting mechanisms includes a left egg-collecting component 41 and a right egg-collecting component 42. The left egg-collecting component 41 and the right egg-collecting component 42 are interlocked to form multiple egg-carrying spaces in a single row. The egg-carrying spaces of each row of egg-collecting mechanisms are located inside the egg-collecting frame component 43 and form an openable and closable egg-carrying space with the egg-collecting frame component 43. They are all tightened in the left and right directions by the elastic tensioning part 44, so that the egg-carrying space is closed in the free state. When the eggs are released, the upper part of the egg-carrying space gradually closes, the elastic tensioning part is tightened and stretched, and the lower part of the egg-carrying space gradually opens to release the eggs.

[0107] In one embodiment, the left egg receiving assembly 41 and the right egg receiving assembly 42 are arranged symmetrically in the left-right direction;

[0108] Both the left egg receiving assembly 41 and the right egg receiving assembly 42 include:

[0110] in, Figure 5 The upper middle rod 11 and the lower left rod 12 pass through the two holes on the limiting fixing block 14, and the three parts are fixed together using the locking nut 15. Similarly, the left rotating gear 13 and the egg catcher fixing seat 17 are fixed with the upper rod 11 and the lower left rod 12 using the same method. The egg catcher 16 is fixed to the egg catcher fixing seat 17 with screws. Figure 5 Both the egg catcher 16 and the egg catcher fixing base 17 can be 12 pieces. Only one piece is shown in the schematic diagram, and the other eleven pieces are hidden to observe their structure.

[0111] Egg catcher 16: Multiple egg catchers 16 with inward openings are arranged in sequence on the support rod, and two opposing egg catchers 16 form an egg-carrying space.

[0112] The control unit is installed at both ends of the support rod. The control units of the left egg receiving assembly and the right egg receiving assembly can rotate relative to each other after being closed.

[0113] The right egg receiving assembly 42 is installed in the same way as the left egg receiving assembly 41. The right rotating gear 21 and the left rotating gear 13 mesh with each other, which is the control unit. The right lower rod 22 and the left lower rod 12 are different in length.

The right frame is connected by an inner adjusting opening and closing rod 31 (i.e., the right inner adjusting opening and closing rod 35), an outer adjusting opening and closing rod 34 (i.e., the right outer adjusting opening and closing rod 36), and a synchronous sliding block 33, which are also connected by two adjusting opening and closing rod pins 39.

[0122] The connecting rod 32 has threaded holes at both ends, and bolts are used to connect the connecting rod 32 to the synchronous sliding block 33. The inner adjusting opening and closing rod 31 and the right inner adjusting opening and closing rod 35 are mirror images of each other, and the outer adjusting opening and closing rod 34 and the right outer adjusting opening and closing rod 36 are mirror images of each other. The sliding bearing 37 is connected to the inner adjusting opening and closing rod 31, the outer adjusting opening and closing rod 34, the right inner adjusting opening and closing rod 35, and the right outer adjusting opening and closing rod 36 respectively by bearing pins 38. Two adjusting rod pins 39 pass through the inner horizontal slot 31B, support hole 33B, and outer horizontal slot 34B of the inner adjusting rod 31, connecting the three parts together. Similarly, the other end is connected in the same way. Because the adjusting rod pins 39 pass through the inner horizontal slot 31B and outer horizontal slot 34B, the inner adjusting rod 31 and outer adjusting rod 34 can slide back and forth. The sliding range is limited by the inner horizontal slot 31B and outer horizontal slot 34B. The same applies to the other side.

[0123] Both ends of the upper rod 11 in the left egg receiving assembly 41 and the right egg receiving assembly 42 are inserted into the upper rod connecting hole 33A of the synchronous sliding block 33, respectively. The left rotating gear 13 in the left egg receiving assembly and the right rotating gear 21 in the right egg receiving assembly mesh with each other. The left and right ends of the elastic tensioning part 44 are connected to the lower left rod 12 in the left egg receiving assembly and the lower right rod 22 in the right egg receiving assembly, respectively. The lower left rod 12 is shorter than the lower right rod 22. After installation, one end of the lower left rod 12 will be inserted into the inner vertical bar hole 31A in the inner adjusting opening and closing rod 31, and the other end will be inserted into the same symmetrical position. The lower right rod 22 is relatively long. After installation, this part passes through the rectangular hole 31C in the inner adjusting rod 31 and then into the outer vertical hole 34A in the outer adjusting rod 34. This way, the inner adjusting rod 31 will not affect the lower right rod 22 during left and right sliding, because the lower right rod 22 passes through the rectangular hole 31C in the inner adjusting rod 31. Similarly, the outer adjusting rod 34 will not affect the lower left rod 12 during left and right sliding, because the lower left rod 12 is shorter and will not contact the outer adjusting rod 34. Thus, when the inner adjusting rod 31 slides left and right, it only controls the lower left rod 12, and when the outer adjusting rod 34 slides left and right, it only controls the lower right rod 22. The elastic tensioning part 44 can be a tension spring.

[0124] See appendix Figure 9-11 In the free state: the left egg receiving assembly 41 and the right egg receiving assembly 42 are in the closed state under the action of the tension spring, such as... Figure 9 In the first state diagram, the lower planes of the left rotating gear 13 and the right rotating gear 21 support each other to form a limit, waiting for the egg to enter the egg-collecting component. Once the egg enters, it is caught by the egg-collecting grabber 16. Figure 9As shown in the second state diagram, after the egg enters, it needs to be released. Simply move the two lower left levers 12 to the left and the two lower right levers 22 to the right. At this time, the spring is in the stretched state, and the left and right egg-receiving components open, allowing the egg to leak out from below. Figure 9 The third state diagram is shown.

[0125] Figure 10 The outer adjusting rod 34 is connected to the synchronous sliding block 33 by the adjusting rod pin 39. When an external force (the arrow indicates the direction of the external force) pushes the sliding bearing 37 to the right, the outer adjusting rod 34 also moves to the right. At this time, the outer adjusting rod 34 will push the lower right rod 22 to the right. Similarly... Figure 11 When an external force (arrow direction indicates the direction of the external force) pushes the sliding bearing 37 to the left, the inner adjusting rod 31 also moves to the left. At this time, the inner adjusting rod 31 will push the lower left rod 12 to the left, thereby controlling the opening state of the egg receiving component.

[0126] It is worth noting that the external force here is applied by the inclined structure on the egg-receiving opening and closing guide rail 98 in the transfer device 152 described below.

[0127] In embodiments of the present invention, the drive mechanism 151 includes: (see attached diagram) Figure 12-14 ,

[0128] Cam assembly 141 includes a fast synchronizing cam 133 and a slow synchronizing cam 135, which are connected by a camshaft 131; the fast synchronizing cam 133 and the slow synchronizing cam 135 have different external profiles.

[0129] The drive linkage assembly 142 includes two independent planar four-bar linkages: a fast synchronous drive assembly connected to the fast conveyor line of the transfer system and a slow synchronous drive assembly connected to the slow conveyor line of the transfer system. The fast synchronous drive assembly is connected to the fast synchronous cam 133, and the slow synchronous cam 135 is connected to the slow synchronous drive assembly.

[0130] The driver drives the camshaft to rotate, which in turn drives the synchronous cam 133 and the slow synchronous cam 135 to rotate.

[0131] The drive linkage assembly in the above technical solution includes two independent planar four-bar linkages. Driven by fast and slow synchronous cams, it can perfectly match the fast and slow conveyor lines of the transfer system, complete the synchronous transfer of poultry eggs in two directions, thereby improving production capacity.

[0132] In one embodiment, the fast synchronization cam 133 has an annular first mounting groove on its inner side, and the slow synchronization cam 135 has an annular second mounting groove on its inner side. The first mounting groove is connected to the fast synchronization drive assembly, and the second mounting groove is connected to the slow synchronization drive assembly.

[0133] Advantageously, specifically, see Appendix Figure 14 The fast synchronization drive assembly includes: a fast synchronization drive swing arm 1211, which has a first connection point at its top and a second connection point at its bottom, on which an active swing arm positioning shaft 1210 is connected; a bearing pin 122 is located at the middle of its outer side, and the bearing pin 122 is inserted into a first mounting groove, on which a fast cam bearing 123 is mounted; a fast synchronization link 1212, one end of which is connected at the first connection point; and two fast passive swing arms 1214, one of which is connected at its middle to the other end of the fast synchronization link 1212, and its top is connected to the top of the other fast passive swing arm 1214 via a fast passive swing arm fixing rod 1213; the bottoms of the two fast passive swing arms 1214 are respectively connected to the two ends of a passive swing arm positioning shaft 1215.

[0134] The slow synchronous drive assembly includes: a slow synchronous drive swing arm 124, the bottom of which is connected to the end of the active swing arm positioning shaft 1210 away from the fast synchronous drive swing arm 1211 via a swing arm bearing 129; another bearing pin 122 is fixed to the outer side of its middle portion, and the bearing pin 122 is inserted into a second mounting groove; a slow cam bearing 123 is mounted on the other bearing pin 122; a slow synchronous connecting rod 126, one end of which is connected to the top of the slow synchronous drive swing arm 124; a slow synchronous passive swing arm 128, the other end of which is connected to the middle portion of the slow synchronous passive swing arm 128; its bottom is connected to the end of the passive swing arm positioning shaft 1215 away from the fast synchronous connecting rod 1212 via another swing arm bearing 129; and a connecting pin 127 is connected to the outer side of the top of the slow synchronous passive swing arm 128.

[0135] Therefore, the fast synchronous drive swing arm 1211 and the slow synchronous drive swing arm 124 are mounted on the active swing arm positioning shaft 1210. A swing arm bearing 129 is installed inside the slow synchronous drive swing arm 124. The fast synchronous drive swing arm 1211 and the slow synchronous drive swing arm 124 can rotate independently around the active swing arm positioning shaft 1210. Similarly, the passive swing arm positioning shaft 1215 is mounted on the connecting rod square bearing 121. The fast passive swing arm 1214 and the slow synchronous passive swing arm 128 are mounted on the passive swing arm positioning shaft 1215. The slow synchronous passive swing arm 128 is connected to the passive swing arm positioning shaft 1215 internally using a swing arm bearing 129. The slow synchronous passive swing arm 128 and the fast passive swing arm 1214 can rotate independently around the passive swing arm positioning shaft 1215.

[0136] In other embodiments, both ends of the active swing arm positioning shaft 1210 and the passive swing arm positioning shaft 1215 are connected to connecting rod square bearings 121, which are connected to the frame by fasteners. In the above scheme, both the fast synchronizing cam 133 and the slow synchronizing cam 135 are mounted on the camshaft 131 via shrink sleeves 134. In the above scheme, both ends of the camshaft 131 are equipped with cam square bearings 132, which are fixed to the frame.

[0137] Advantageously, both ends of the fast synchronizing link 1212 and both ends of the slow synchronizing link 126 are connected to spherical bearings 125. That is, after the spherical bearings 125 are installed at both ends of the slow synchronizing link 126, the spherical bearings connect the slow synchronizing drive arm 124 and the slow synchronizing passive arm 128, forming a planar four-bar linkage. These four links are the slow synchronizing drive arm 124, the slow synchronizing passive arm 128, the slow synchronizing link 126, and the frame. Similarly, after the spherical bearings 125 are installed at both ends of the fast synchronizing link 1212, the spherical bearings connect the fast synchronizing drive arm 1211 and the fast synchronizing passive arm 1214, forming a planar four-bar linkage. The fast synchronizing passive arm fixing rod 1213 connects the two fast synchronizing passive arms 1214 together. These four links are the fast synchronizing drive arm 1211, the fast synchronizing passive arm 1214, the fast synchronizing link 1212, and the frame. Two of the fast passive swing arms 1214 are designed to provide a fast passive swing arm fixing rod 1213 for driving stability.

[0138] In the above scheme, the fast passive swing arm fixing rod 1213 is connected to the fast conveyor line of the transfer system; the connecting pin 127 is connected to the slow conveyor line of the transfer system.

[0139] Thus, the drive linkage assembly forms two independent planar four-bar linkages: one is a fast synchronous drive mechanism, and the other is a slow synchronous drive mechanism. These two independent drive mechanisms are connected to the synchronous transfer component via linkages. The cam bearings 123 on the slow synchronous drive arm 124 and the fast synchronous drive arm 1211 in the drive linkage assembly 142 are respectively engaged in the annular grooves of the slow synchronous cam 135 and the fast synchronous cam 133.

[0140] The drive mechanism can contain at least a motor that drives the camshaft to rotate. The camshaft drives the entire drive linkage assembly 142 to move, which in turn drives the fast conveyor line through the fast passive swing arm fixing rod 1213 and the slow conveyor line through the connecting pin 127. This achieves synchronous driving of the fast and slow conveyor lines in different directions.

[0147] Synchronous transfer device 152 includes:

[0148] The transfer base plate assembly 111 includes a rectangular base plate 81 fixed on the frame. Four longitudinally arranged guide rails (slow-speed synchronous guide rail A82, slow-speed synchronous guide rail B83, slow-speed synchronous guide rail C86, and slow-speed synchronous guide rail D87) are fixed at the four corners of the rectangular base plate 81. Two guide rails (fast-speed synchronous guide rail 84) are arranged horizontally within the area enclosed by the four guide rails. A guide rail (slow-speed drive guide rail 85) is arranged parallel to the guide rails on the edge of the rectangular base plate 81. The length of the guide rail is greater than the length of the guide rails, and the length of the guide rails is greater than the length of the guide rails.

[0149] The slow moving frame assembly 112 slides on the guide rail 1, and a slow pushing bearing 96 is installed on the top of one side of it. The egg receiving device 153 is connected to the slow moving frame assembly 112 through the egg receiving drive connecting rod 156.

[0150] The slow synchronous drive assembly 113 slides on the guide rail three, which has a slanted groove to guide the movement of the slow push bearing and is connected to the slow drive connecting rod 155.

[0151] The rapid moving frame assembly 116 slides on the guide rail 2 and is connected to the rapid drive connecting rod 154. The egg receiving device 153 slides relative to the rapid moving frame assembly 116.

[0152] More advantageously, the slow-moving box component 112 includes:

[0153] The slow frame has four vertical sliders at the four corners of its bottom that slide in conjunction with four guide rails; one long frame at the top has a slow frame groove 92 that contacts one end 156A of the egg-catching drive connecting rod, and the other long frame has a slow frame bearing pin 97 for mounting a slow speed push bearing 96; the slow frame is enclosed by a passive connecting rod 91, a left connecting plate 93, an active connecting rod 95, and a right connecting plate 910.

[0154] There are four egg-receiving opening and closing guide rails 98, located at the four corners of the slow frame and fixed by guide rail fixing plates 99, which apply a pushing force to the egg-receiving device 153.

[0155] The slow-speed frame, consisting of the passive connecting rod 91, left connecting plate 93, active connecting rod 95, and right connecting plate 910, has slow-speed sliders 94 at each of its four corners. These components are bolted together to form a frame structure with sliders at the four corners. The slow-speed frame groove 92 is fixed within the groove of the passive connecting rod 91. The slow-speed push bearing 96 is fixed to the active connecting rod 95 via a slow-speed frame bearing pin 97. Guide rail fixing plates 99 are welded to both the passive connecting rod 91 and the active connecting rod 95. The egg-receiving assembly opening and closing guide rail 98 is bolted to the guide rail fixing plate 99.

[0156] The slow synchronous drive assembly 113 includes two sets of slider joints. The bottom of the two sets of slider joints has a slow synchronous slider 106 that slides with the guide rail, and the upper part has a grooved drive block 101 with a slanted groove. The two sets of slider joints are connected by a synchronous drive connecting rod 105. One end of the assembly has a drive pin 107A that connects to the slow drive connecting rod 155.

[0157] Figure 18 On the left, a pad 103, a slant drive block 101, and a slider connecting plate 102 are placed on the slow-speed synchronous slider 106 and fixed together with bolts. On the right, a pad 103, a slant drive block 101, and a slider drive plate 107 are placed on the slow-speed synchronous slider 106 and fixed together with bolts.

[0158] The quick move box component 116 includes:

[0159] The fast frame has a length and width that are smaller than those of the slow frame. Its bottom has a fast slider that slides in conjunction with the guide rail. The outside of one side of the long frame has a sliding cylindrical sleeve 78 through which the other end 156B of the egg-catching drive connecting rod passes. The short frame near the drive end has a pin lug 72 that connects to the fast drive connecting rod 154.

[0160] The pin-mount bracket 71 and pin-mount lug 72 are welded together. The two ends of the connecting square tube 73 are welded to the pin-mount bracket 71 and the connecting plate 75 respectively to form a quick-release frame. The base plate 74 is welded to the connecting square tube 73. The sliding round rod 76 is bolted to the connecting square tube 73.

[0161] The slow sliders 94 installed at the four corners of the slow moving frame assembly 112 of the present invention are respectively installed on the slow synchronous guide rails A82, B83, C86 and D87, so the slow moving frame assembly 112 can slide on the corresponding guide rails.

[0162] The slow synchronization slider 106 on the slow synchronization drive assembly 113 is mounted on the slow drive guide rail 85 in the transfer base plate assembly 111, so the slow synchronization drive assembly 113 can slide on the corresponding guide rail. The fast movement frame assembly 116 is mounted on the fast synchronization guide rail 84 via a fast slider, so the fast movement frame assembly 116 can also slide on the corresponding guide rail.

[0163] The slow-moving frame assembly 112 has a slow-moving push bearing 96 embedded in the slanted groove of the slanted drive block 101. Therefore, when the slow-moving synchronous drive assembly 113 moves along the 114 direction, the slow-moving frame assembly 112 will move along the 115 direction, and vice versa. The 114 direction is the same as the second directions 165 and 158, and the 115 direction is the same as the first directions 164 and 157.

[0164] This invention provides a planar two-way synchronous transfer system for grading poultry eggs, see attached document. Figure 2 , 23 -28, the drive mechanism 151 is connected to the fast moving frame assembly 116 and the slow synchronous drive assembly 113 in the synchronous transfer device 152 via the fast drive connecting rod 154 and the slow drive connecting rod 155, respectively. The synchronous sliding block 33 in the egg receiving device 153 is installed on the sliding round rod 76 in the synchronous transfer device 152, so that the entire egg receiving device 153 can slide along the sliding round rod 76. The sliding direction is controlled by the slow moving frame assembly 112 in the synchronous transfer device 152 via the egg receiving drive connecting rod 156. The other end 156B of the egg receiving drive connecting rod passes through the sliding cylindrical sleeve 78 and is fitted onto the connecting rod 32 of the egg receiving device 153. One end 156A of the egg receiving drive connecting rod is embedded in the slow frame sliding groove 92 in the slow moving frame assembly 112. When the egg receiving device 153 moves back and forth along the direction of 158, the inclined structure on the egg receiving opening and closing guide rail 98 in the synchronous transfer device 152 controls the movement state of the inner adjusting opening and closing rod 31 and the outer adjusting opening and closing rod 34 of the egg receiving device 153, thereby opening the egg receiving device 153 at the designated position to release the poultry eggs from the egg carrying space.

[0165] When the camshaft 131 rotates, the egg receiving device 153 will reciprocate along two directions, 157 and 158, on a plane, and ensure that the speed of the eggs is synchronized with the speed of the conveyor line during the egg receiving and releasing process.

[0166] Egg-catching process: See Figure 23 and 24The rotation of camshaft 131 drives the slow-speed synchronous cams 135 and 133, and the fast-speed synchronous cams 133 to rotate. When receiving eggs, the fast-speed synchronous cam 133 is in a resting state, while the slow-speed synchronous cam 135 is in the push-stroke working state. At this time, the slow-speed synchronous passive swing arm 128 rotates along direction 171, the slow-speed synchronous drive assembly 113 moves along direction 172, and the inclined groove drive block 101 also moves along direction 172. Driven by the inclined groove plastic block driven by 101, the slow-speed moving frame assembly 112 moves along direction 173. The plastic slide 92 in the slow-speed moving frame assembly 112 pulls the egg receiving device 153 to move together along direction 173. As shown in the figure above, the egg receiving opening and closing guide rail 98 does not apply force to the internal adjusting opening and closing rod 31, and the egg receiving device 153 is in a freely closed state.

[0167] Initially, the egg-catching device 153 accelerates from a standstill. When its speed equals that of the slow conveyor line 161, it stops accelerating and maintains this speed for a period of time. During this time, the eggs fall from the slow conveyor line 161 into the egg-catching device 153. The egg-catching device 153 is in a freely closed state. Therefore, after catching the eggs, the egg-catching device 153 decelerates until it stops. The egg-catching device 153 moves along the direction 173 to its limit stroke. At this point, the egg-catching device 153 is directly above the fast conveyor line 163.

[0168] Egg release process: After the egg release is completed, the mechanism's status is as follows: Figure 25 As shown, at this time, the slow synchronizing cam 135 enters the rest state, and the fast synchronizing cam 133 enters the push-stroke working state. The fast passive swing arm 1214 rotates along the 183 direction under the drive of the fast synchronizing cam 133, driving the entire fast moving frame assembly 116 to move along the 181 direction. Therefore, the egg receiving device 153 moves along the 181 direction together with the fast moving frame assembly 116.

[0169] Egg receiving device 153 starts from a standstill and accelerates until its speed matches that of rapid conveyor line 163 (e.g.) Figure 26 and 27 At this time, the egg-receiving opening and closing guide rail 98 uses the inclined structure to push the inner adjusting opening and closing rod 31 along the 193 direction to the position shown in the figure, so that the egg-receiving opening and closing guide rail 98 is in the open state (e.g. Figure 9 As shown in the third state diagram, the eggs are released by the egg receiving guide rail 98, and at this time the egg receiving guide rail 98 coincides with the rapid conveyor line 163, and the eggs will enter the rapid conveyor line 163 synchronously.

[0170] During the process of the eggs entering the fast conveyor line 163, the egg receiving device 153 always keeps the speed synchronized with the fast conveyor line 163 and maintains this for a period of time. After the eggs have completely entered the fast conveyor line 163, the egg receiving device 153 begins to decelerate under the control of the cam until it comes to a stop.

[0171] Return process: When the egg receiving device 153 finishes releasing the eggs and decelerates to a standstill, the state is as follows: Figure 28 As shown, the egg-catching device 153 then begins to return to its original position. The slow-speed synchronous passive swing arm 128 begins to rotate along direction 202, and the fast-speed passive swing arm 1214 begins to rotate along direction 201. At this time, the egg-catching device 153 has a component velocity along direction 205 and also a component velocity along direction 204. During the return journey, it first accelerates and then decelerates to a standstill, returning to its original position. Figure 23 The initial state.

[0172] The egg-catching device in the above embodiment is based on two rows, but it is also applicable to four rows or more.

[0173] It is worth noting that the resting state of the cam described in this invention is understood as follows: See Appendix Figure 3 The egg-catching device starts at point A. From A to B, the slow cam profile is in the pushing stroke, and the fast cam profile is in the resting state (the cam bearing 123 on the fast bearing pin 122 is in contact with the base circle of the fast cam). At point B, the slow cam profile rests (the cam bearing 123 on the slow bearing pin 122 is in contact with the base circle of the slow cam), and the fast cam profile enters the pushing stroke. After reaching point C, the slow cam profile enters the return stroke, and the fast cam profile also enters the return stroke, returning to point A. This cycle repeats continuously.

[0174] Egg grading equipment with the planar bidirectional synchronous transfer system of the present invention, see attached document. Figure 29 include:

[0175] The above-mentioned schemes for a two-dimensional synchronous transfer system for grading poultry eggs;

[0176] A slow conveyor line located above the planar two-way synchronous transfer system for grading poultry eggs;

[0177] The fast conveyor line is located below the two-way synchronous transfer system for grading poultry eggs; the movement trajectories of the slow conveyor line and the fast conveyor line are perpendicular.

[0178] And the overall drive unit for a planar two-way synchronous transfer system for driving poultry egg grading, a slow conveyor line, and a fast conveyor line.

[0179] Specifically, Figure 29 In the overall drive unit, at least the following components are included: 221 is a servo motor (i.e., the motor in the drive mechanism mentioned above), 223 is a camshaft sprocket, 224 is a high-speed conveyor drive sprocket, 225 is a high-speed conveyor drive shaft, 226 is a high-speed conveyor drive wheel, 227 is a camshaft gear, 228 is a reversing gearbox, 229 is a slow-speed conveyor drive gear, and 2210 is a slow-speed conveyor drive shaft.

[0180] The drive sprocket 222 is fixed to the servo motor 221, which is fixed to the frame. When the servo motor 221 rotates, the drive sprocket 222 drives the camshaft sprocket 223 via a chain. The camshaft sprocket 223 then drives the high-speed conveyor drive sprocket 224 via a chain, causing the high-speed conveyor drive shaft 225 to rotate, thereby driving the entire high-speed conveyor line to move in the direction 2212. The camshaft gear 227 is mounted on the camshaft 131 together with the camshaft sprocket 223 via a key. Therefore, when the camshaft sprocket 223 is driven, the camshaft gear 227 is also driven. Through the reversing gearbox 228, the power is transmitted to the slow-speed conveyor drive gear 229, causing the slow-speed conveyor drive shaft 2210 to rotate, thus causing the entire slow-speed conveyor line to move in the direction 2211.

[0181] It is worth noting that multiple labels are used to illustrate the direction of movement or rotation of each component in each figure. These labels have no limiting meaning and are only used to facilitate the description of the direction of movement or rotation of the components in the corresponding figures. For example, directions 115, 164, 157, 172, 182, and 205 all indicate verticality, and the specific arrows indicate the direction of movement of the corresponding components.

[0182] Directions 114, 165, 158, 174, 181, 191, and 203 all indicate horizontal, with the specific arrows indicating the direction of movement of the corresponding components.
