[0045] In other embodiments, the number of the automated fishing bait packaging production lines may be one or more.

[0046] Figure 2 This is a schematic structural diagram of the automatic bait packaging system 1000 provided in this embodiment when the vacuum packaging machine 1002 is omitted.

[0047] See also Figure 2 The bait cake machine 1001, fishing bait cake guide and conveyor device 100, vacuum packaging machine 1002, and gripping device 300 provided in this embodiment are arranged around the material receiving and sorting device 200. In this embodiment, the fishing bait cake guide and conveyor device 100 is used to slide the bait cakes 1 from the bait cake machine 1001 into and move them. It includes a conveyor frame 10, whose surface has a mutually perpendicular transverse direction (direction D1 shown in the figure, collectively referred to as the first direction D1 below) and a longitudinal direction (direction D2 shown in the figure, collectively referred to as the first direction D2 below). The number of bait cake machines 1001 is but not limited to two. The two bait cake machines 1001 are arranged side by side and at intervals in a direction parallel to the first direction D1. The square bait cake diversion and conveying device 100 for fishing is arranged on the same side of the two bait cake machines 1001. The material receiving and sorting device 200 is docked with the square bait cake diversion and conveying device 100 for fishing along a direction parallel to the first direction D1. The vacuum packaging machine 1002 is arranged on one side of the material receiving and sorting device 200, and the gripping device 300 is arranged between the vacuum packaging machine 1002 and the material receiving and sorting device 200.

[0048] See also Figures 2 to 8 The square bait cake diversion and conveying device 100 for fishing in this embodiment includes a feeding tray 70, a conveyor frame 10, a conveyor belt 20, a conveyor belt drive assembly 30, an upstream diversion mechanism 40, a reversing mechanism 50, and a downstream diversion mechanism 60. The conveyor belt 20, the conveyor belt drive assembly 30, the upstream diversion mechanism 40, the reversing mechanism 50, and the downstream diversion mechanism 60 are all supported on the conveyor frame 10, and the feeding tray 70 is disposed on one side of the conveyor frame 10.

[0049] See also Figure 3 and 4 In this embodiment, the conveyor belt 20 is used to hold the square bait cakes 1. The conveyor belt 20 is rotatably mounted on the conveyor frame 10. The conveyor belt drive assembly 30 rotates the conveyor belt 20, thereby moving the square bait cakes 1 placed on the conveyor belt 20. In this embodiment, the conveyor belt drive assembly 30 is, but is not limited to, a servo motor drive assembly. Driven by the conveyor belt drive assembly 30, the conveyor belt 20 rotates, thereby moving the square bait cakes 1 placed thereon in a direction parallel to the first direction D1.

[0050] See also Figure 3 and 4 In this embodiment, the upstream guide mechanism 40 is arranged above the conveyor belt 20. The upstream guide mechanism 40 includes an upstream guide channel 41. The bait cakes 1 of the supply side move one by one and in an orderly manner in the upstream guide channel 41. The upstream guide channel 41 extends roughly in a direction parallel to the first direction D1. In this embodiment, the number of the upstream guide channels 41 is but not limited to two. The two upstream guide channels 41 are basically parallel and are arranged side by side in a direction parallel to the second direction D2.

[0051] See also Figure 3 and 4 In this embodiment, the upstream guide mechanism 40 includes a plurality of upstream guide bars 42 extending along the moving direction of the square bait cake 1 (i.e., a direction parallel to the direction D1 in the figure), and the plurality of upstream guide bars 42 are spaced apart in a direction parallel to the second direction D2, and an upstream guide channel 41 is formed between adjacent upstream guide bars 42.

[0052] Specifically, the upstream flow guiding mechanism 40 further includes an upstream flow guiding bracket 43 , and the upstream flow guiding strips 42 are held on the upstream flow guiding bracket 43 in an adjustable spacing manner;

[0053] See also Figure 3 and 4The dropping tray 70 of this embodiment is arranged on the peripheral side of the conveyor frame 10 and is located above the conveyor belt 20. The dropping tray 70 has a material receiving trough 71, a first material dropping channel 72 and a second material dropping channel 73 connected to the outlet of the bait cake machine 1001. The first material dropping channel 72 extends from the material receiving trough 71 to the entrance of one of the two upstream guide channels 41, and the second material dropping channel 73 extends from the material receiving trough 71 to the entrance of the other of the two upstream guide channels 41; the dropping tray 70 is provided with a channel switching component 74 which can selectively guide the square bait cake 1 in the material receiving trough 71 into one of the first material dropping channel 72 and the second material dropping channel 73. In this embodiment, the drop tray 70 is arranged between the bait cake machine 1001 and the conveyor frame 10. The square bait cake 1 made by the bait cake machine 1001 falls onto the conveyor belt 20 through the drop tray 70. The drop tray 70 extends downward from the bait cake machine 1001 in a direction parallel to the second direction D2. The receiving trough 71 is located above the first dropping channel 72 and the second dropping channel 73. The first dropping channel 72 and the second dropping channel 73 are arranged side by side in a direction parallel to the first direction D1. Under the action of its own gravity, the square bait cake 1 slides from the outlet of the bait cake machine 1001 into the receiving trough 71, and slides into the corresponding upstream guide channel 41 from the first dropping channel 72 or the second dropping channel 73.

[0054] from Figure 3 As can be seen, in this embodiment, each upstream diversion channel 41 is provided with a stockpile sensor 75 for detecting the accumulation of bait cakes 1 in the upstream diversion channel 41. When accumulation of bait cakes 1 is detected in one upstream diversion channel 41, the channel switching assembly 74 is controlled to open another upstream diversion channel 41. In this embodiment, the number of stockpile sensors 75 is, but is not limited to, two. Two stockpile sensors 75 are respectively provided in two upstream diversion channels 41. When one upstream diversion channel 41 is full of bait cakes 1, the stockpile sensor 75 sends a signal to the main control board (not shown), which controls the channel switching assembly 74 to direct the bait cakes 1 in the upstream diversion channel 41 to the other upstream diversion channel 41. In particular, the stockpile sensor 75 can be any existing sensor in the prior art capable of performing the above-mentioned detection, and the main control board can be any existing main control board in the prior art capable of performing communication and control.

[0055] Specifically, a stacking sensor support frame is provided on the conveyor frame 10, and the stacking sensor 75 is fixed on the stacking sensor support frame.

[0056] Please continue to see Figure 3In this embodiment, the number of bait cake machines 1001 is, but is not limited to, two. The two bait cake machines 1001 are arranged side by side and spaced apart in a direction parallel to the first direction D1. The number of the feeding trays 70 is, but is not limited to, two. The two feeding trays 70 are arranged side by side and spaced apart in the direction of movement of the square bait cakes 1. The two feeding trays 70 correspond one-to-one to the two bait cake machines 1001, respectively. The stacking sensor 75 is disposed between the two feeding trays 70. It should be noted that, according to production needs, two bait cake machines 1001 can be provided to discharge bait simultaneously, thereby increasing production. By arranging the stacking sensor 75 between the two feeding trays 70, the number of square bait cakes 1 in an upstream diversion channel 41 can be guaranteed, and blockage of the upstream diversion channel 41 caused by an excessive number of square bait cakes 1 can be avoided.

[0057] from Figure 4 As can be seen, in this embodiment, the material drop tray 70 includes an inclined tray bottom plate 76 and tray side plates 77 connected to both sides of the tray bottom plate 76. The material receiving trough 71 is formed between the tray bottom plate 76 and the tray side plates 77. A partition plate 78 is provided within the material drop tray 70, and the first material drop channel 72 and the second material drop channel 73 are formed between the partition plate 78 and the tray side plates 77. The channel switching assembly 74 includes a channel switching cylinder 741 and a channel switching plate 742 for abutting the piston rod of the channel switching cylinder 741; the channel switching plate 742 is pivotally attached to the tray side plates 77.

[0058] Specifically, the channel switching assembly 74 is disposed above the first blanking channel 72 and the second blanking channel 73. A guide ramp 79 is disposed within the blanking tray 70. The guide ramp 79 is disposed above the channel switching assembly 74 and corresponds to the second blanking channel 73. The channel switching plate 742 is located on the tray side plate 77 on the side of the first blanking channel 72, and the guide ramp 79 is located on the tray side plate 77 on the side of the second blanking channel 73. The guide ramp 79 extends downward from the tray side plate 77 and obliquely toward the first blanking channel 72. When the piston rod of the channel switching cylinder 741 is not pushed out, the channel switching plate 742 is laid flat on the side plate 77 of the disc. At this time, the entrance of the first blanking channel 72 is in an open state, and the second blanking channel 73 is blocked by the guide ramp 79, so that the square bait cake 1 in the receiving trough 71 falls directly into the first blanking channel 72 from the surface of the guide ramp 79; when the stacking sensor 75 senses the stacking situation, the piston rod of the channel switching cylinder 741 is driven out by the main control board, and the channel switching plate 742 is pushed into the receiving trough 71 and blocked above the first blanking channel 72 in an inclined state. The square bait cake 1 in the receiving trough 71 falls into the second blanking channel 73 through the surface of the guide ramp 79 and the surface of the channel switching plate 742, realizing the blanking switching between the first blanking channel 72 and the second blanking channel 73.

[0059] Please continue to see Figure 4In this embodiment, a waste box 701 is connected to the outside of the drop tray 70, and a waste discharge port 702 is provided on the side plate 77 of the drop tray. A waste discharge assembly 703 is provided on the drop tray 70 to push unqualified square bait cakes 1 into the waste box 701. In this embodiment, a waste sensor (not shown) is provided at the outlet of the bait cake machine 1001. The waste discharge assembly 703 includes a discharge plate 704 pivotally attached to the waste discharge port 702 of the side plate 77 of the drop tray, and a discharge cylinder 705 fixed to the drop tray 70. The piston rod of the discharge cylinder 705 is connected to the discharge plate 704. In this way, when the waste sensor detects a square bait cake with an abnormal shape, the piston rod of the discharge cylinder 705 retracts, pulling the discharge plate 704 to swing into the receiving trough 71, causing the unqualified square bait cakes to fall from the waste discharge port 702 into the waste box 701.

[0060] See also Figure 5 and 6 In this embodiment, the upstream flow guiding mechanism 40, the reversing mechanism 50, and the downstream flow guiding mechanism 60 are disposed above the conveyor belt 20 and arranged sequentially in the direction of movement of the square bait cakes 1 (i.e., parallel to the direction D1 in the figure). The downstream flow guiding mechanism 60 includes a downstream flow guiding channel group 60a, which includes downstream flow guiding channels 61 for the square bait cakes 1 to move one by one and in an orderly manner within the downstream flow guiding channels 61. The downstream flow guiding channels 61 extend generally parallel to the first direction D1. The reversing mechanism 50 includes a reversing channel 51 and a reversing drive assembly 52. The reversing channel 51 has an inlet and an outlet. The inlet communicates with the outlet of the upstream flow guiding channel 41. The reversing drive assembly 52 selectively connects the outlet of the reversing channel 51 to the inlet of the downstream flow guiding channels 61 in the downstream flow guiding channel group 60a. It can be understood that the upstream guide mechanism 40 and the downstream guide mechanism 60 are used to guide the movement of the square bait cakes 1, and the downstream guide channel group 60a of the downstream guide mechanism 60 and the reversing mechanism 50 are used to realize the diversion of the square bait cakes 1 in the upstream guide mechanism 40, thereby increasing the number of columns of the square bait cakes 1 in the direction parallel to the second direction D2, so as to increase the number of square bait cakes 1 grabbed at one time and reduce the number of times they are grabbed.

[0061] See also Figure 5 and 6In this embodiment, the number of downstream guide channel groups 60a is, but is not limited to, two. The two downstream guide channel groups 60a correspond one-to-one with the two upstream guide channels 41. The number of downstream guide channels 61 in each downstream guide channel group 60a is, but is not limited to, two. The two downstream guide channels 61 are substantially parallel and arranged side by side in a direction parallel to the second direction D2. Specifically, the number of reversing channels 51 is, but is not limited to, two. The two reversing channels 51 and the two downstream guide channel groups 60a correspond to the two upstream guide channels 41. That is, each reversing channel 51, driven by the reversing drive assembly 52 connected thereto, selectively switches the outlet end of the reversing channel 51 and connects to one of the inlet ends of the two downstream guide channels 61 in the corresponding downstream guide channel group 60a.

[0062] See also Figure 5 and 6 In this embodiment, the downstream flow guiding mechanism 60 includes a plurality of downstream flow guiding strips 62 extending along the direction of movement of the square bait cake 1 (i.e., parallel to the direction D1 in the figure). The plurality of downstream flow guiding strips 62 are spaced apart in a direction parallel to the second direction D2, and downstream flow guiding channels 61 are formed between adjacent downstream flow guiding strips 62. It should be noted that the width dimensions (i.e., the length dimension in a direction parallel to the second direction D2) of the upstream flow guiding channel 41 and the downstream flow guiding channel 61 are substantially the same and are adapted to the dimensions of the square bait cake 1.

[0063] Specifically, the downstream flow guiding mechanism 60 further includes a downstream flow guiding bracket 63 , and the downstream flow guiding strips 62 are held on the downstream flow guiding bracket 63 in an adjustable spacing manner.

[0064] See also Figure 5 and 6 In this embodiment, each downstream diversion channel 61 is provided with a full-fill sensor 64 for detecting the accumulation of bait cakes 1 in the downstream diversion channel 61. When an accumulation of bait cakes 1 is detected in a downstream diversion channel 61, the diversion mechanism 50 is controlled to open another downstream diversion channel 61. In this embodiment, the number of full-fill sensors 64 is, but not limited to, four. Four full-fill sensors 64 are respectively provided in the four downstream diversion channels 61. When the bait cakes 1 in one of the downstream diversion channels 61 are full, the full-fill sensor 64 sends a signal to the main control board (not shown), which controls the diversion mechanism 50 to direct the bait cakes 1 in the upstream diversion channel 41 to another downstream diversion channel 61. In particular, the full-fill sensor 64 can be any existing sensor in the prior art capable of performing the above-mentioned detection, and the main control board can be any existing main control board in the prior art capable of performing communication and control.

[0065] Specifically, a full material sensor support frame 65 is provided on the conveyor frame 10 of this embodiment, and the full material sensor 64 is fixed on the full material sensor support frame 65.

[0066] See also Figures 6 to 8 The reversing mechanism 50 of this embodiment includes a reversing support frame 53 fixed to the conveyor frame 10; a reversing drive assembly 52 including two reversing plates 521 pivotally attached to the reversing support frame 53 and parallel to each other; and a reversing cylinder 522 for rotating the reversing plates 521. The reversing cylinder 522 is fixed to the reversing support frame 53 and connected to each of the two reversing plates 521. The two reversing plates 521 are spaced apart and form a reversing channel 51 therebetween. In this embodiment, there are two sets of reversing drive assemblies 52, symmetrically arranged on the reversing support frame 53. Each reversing plate 521 is connected to a reversing shaft 523 and a reversing rocker 524. The reversing shaft 523 is rotatably mounted on the reversing support frame 53. The reversing plate 521 and the reversing rocker 524 are non-rotatably connected to the ends of the reversing shaft 523. The reversing drive assembly 52 also includes an adapter plate 525, to which the piston rod of the reversing cylinder 522 and the reversing rocker 524 are hingedly connected. The reversing cylinder 522 is controlled by the main control board. As the piston rod extends and retracts, the two adapter plates 525 swing simultaneously, achieving channel switching.

[0067] from Figures 6 to 8 As can be seen, in this embodiment, the reversing plate 521 is made of an elastically deformable material, and the reversing drive assembly 52 further includes a reversing clamping cylinder 526, which is fixed to one of the two reversing plates 521, and the piston rod of the clamping cylinder is connected and fixed to the other of the two reversing plates 521. It should be noted that before the reversing cylinder 522 is actuated, the clamping cylinder first controls the reversing plate 521 to clamp the square bait cake 1 to restrict its movement, and then the reversing cylinder 522 drives the square bait cake 1 to swing. This prevents the reversing plate 521 from swinging and causing the square bait cake 1 to become stuck with the downstream guide bar 62 when the square bait cake 1 is only partially removed from the reversing plate 521, thereby preventing the reversing plate 521 from swinging normally.

[0068] See also Figure 9 The conveyor frame 10 of this embodiment has a discharging station docking with the material receiving and sorting device 200, and a pressing device 80 is provided on the discharging station of the conveyor frame 10 to press the square bait cake 1 on the conveyor belt 20 downward.

[0069] See also Figure 9 The pressing device 80 of this embodiment includes a pressing support frame 81, a pressing wheel 82 and a pressing wheel connecting rod 83. The pressing support frame 81 is fixed to the conveyor frame 10, the pressing wheel connecting rod 83 is fixed to the pressing support frame 81, and the lower pressing wheel 82 is rotatably supported on the pressing wheel connecting rod 83.

[0070] See also Figure 9 In this embodiment, the number of pressure wheel connecting rods 83 is but not limited to four. The four pressure wheel connecting rods 83 correspond one to one to the four downstream guide channels 61. A lower pressure wheel 82 is installed at the outer end of each pressure wheel connecting rod 83. It should be noted that the lower pressure wheel 82 is used to press the square bait cake 1 in the downstream guide channel 61, thereby increasing the friction between the square bait cake 1 and the conveyor belt 20, and increasing the sliding distance of the square bait cake 1 after it is sent away from the conveyor belt 20.

[0071] See also Figure 9 In this embodiment, the lower pressing wheel 82 can adopt a first lower pressing wheel 82a and a second lower pressing wheel 82b with a smaller diameter than the first lower pressing wheel 82a according to needs.

[0072] As a further optimization, a torsion spring (not shown) is provided between the pressure wheel connecting rod 83 and the lower pressure support frame 81, so that the lower pressure wheel 82 can elastically abut against the square bait cake 1.

[0073] See also Figure 9 In this embodiment, a bait cake limiting device 90 is provided at the discharge station of the conveyor frame 10 to limit the movement of the square bait cake 1 in a direction perpendicular to the surface of the conveyor belt 20; the bait cake limiting device 90 is located downstream of the pressing device 80 in the direction of movement of the square bait cake 1. It should be noted that since the material receiving and sorting tray of the material receiving and sorting device 200 can be raised and lowered relative to the conveyor frame 10, when the material receiving and sorting tray is raised and lowered, it is easy to drive the square bait cake 1 located at the outermost end of the conveyor belt 20 to move upward and off the conveyor belt 20. By providing the bait cake limiting device 90, the square bait cake 1 can be kept on the conveyor belt 20 when the material receiving and sorting tray is raised and lowered, thereby avoiding waste of the conveyor belt 20.

[0074] Please continue to see Figure 9The bait cake limiting device 90 of this embodiment includes a bait cake limiting bracket 91 and a bait cake limiting pressure block 92 fixed to the bracket 91 and used to abut the top surface of the square bait cake 1. The bait cake limiting bracket 91 is fixed to the conveyor frame 10. In this embodiment, the bait cake limiting bracket 91 includes a bait cake limiting support rod 93, a bait cake limiting mounting block 94, and a bait cake limiting upright rod 95. The bait cake limiting support rod 93 is fixed above the conveyor frame 10, the bait cake limiting mounting block 94 is mounted on the bait cake limiting support rod 93, and the bait cake limiting pressure block 92 is retained on the bait cake limiting mounting block 94 by the bait cake limiting upright rod 95. The bait cake limiting support rod 93 has a square cross-section, and the bait cake limiting upright rod 95 also has a square cross-section. It is worth mentioning that the rod with a square cross-section has a self-guiding effect. The bait cake limiting support rod 93 with a square cross-section is used to avoid relative rotation due to loosening between the bait cake limiting mounting block 94 and the bait cake limiting support rod 93 after a period of use; the bait cake limiting vertical rod 95 with a square cross-section is used to avoid relative rotation due to loosening between the bait cake limiting mounting block 94 and the bait cake limiting vertical rod 95 after a period of use, thereby ensuring the stability of the structure.

[0075] See also Figures 10 to 12The material receiving and sorting device 200 of this embodiment includes a material receiving base 201, a material blocking bar 202 and a material receiving and sorting tray 203 supported on the material receiving base. The material receiving base 201 is provided with a Y-axis material receiving drive module 204 for driving the material receiving and sorting tray 203 to move horizontally and a Z-axis material receiving drive module 205 for driving the material receiving and sorting tray 203 to move up and down. The material receiving and sorting tray 203 is provided with a material grid 206 for placing the square bait cake 1; the material blocking bar 202 is provided between the material receiving and sorting tray 203 and the conveyor frame 10, and a material feeding notch 207 is provided on the material blocking bar 202. In this embodiment, the Y-axis material receiving drive module 204 is but not limited to a motor drive module, which can drive the material receiving and sorting tray 203 to move relative to the material receiving base 201 in a direction parallel to the second direction D2, and the Z-axis material receiving drive module 205 is but not limited to a cylinder drive module, which can drive the material receiving and sorting tray 203 to move up and down relative to the material receiving base 201. The number of feed inlets 207 on the retaining bar 202 is, but is not limited to, one. The width of the feed inlets 207 (the length in a direction parallel to the second direction D2) is slightly greater than the width of four downstream flow guide channels 61 (the length in a direction parallel to the second direction D2). This allows four square bait cakes 1 to pass through simultaneously. The number of the material compartments 206 is, but is not limited to, four. The four material compartments 206 are arranged sequentially along a direction parallel to the second direction D2. It is worth noting that the width of each material compartment 206 (the length in a direction parallel to the second direction D2) matches the width of the feed inlets 207. In other words, each material compartment 206 can accommodate four square bait cakes 1. The length of each material compartment 206 (the length in a direction parallel to the first direction D1) is the sum of the lengths of twelve square bait cakes 1. In other words, when the material compartments 206 are full, each material compartment 206 can accommodate a maximum of forty-eight square bait cakes 1.

[0076] In particular, the grabbing device 300 of this embodiment only grabs the square bait cakes 1 in three material grids 206 connected in sequence at a time. In this way, the remaining material grids 206 can be fed continuously, thereby realizing uninterrupted feeding operations and improving production efficiency.

[0077] Please continue to see Figures 10 to 12 In this embodiment, a powder leakage hole 208 is provided at the bottom of the material receiving and sorting tray 203, and a powder recovery box 209 is provided below the material receiving and sorting tray 203.

[0078] See also Figure 13The gripping device 300 of this embodiment reciprocates between the receiving and sorting device 200 and the vacuum packaging machine 1002 and is used to grasp the square bait cakes 1. The gripping device 300 comprises a gripping mounting bracket 301 and a plurality of clamping mechanisms 302 disposed on the gripping mounting bracket 301 and arranged in a rectangular array. Each clamping mechanism 302 comprises a pair of clamping plates 303 for grasping the square bait cakes 1 and a clamping cylinder 304 for opening and closing the clamping plates 303. In this embodiment, the gripping device 300 is mounted on a multi-axis robot 400, which is any conventional robot capable of performing the lifting and rotating motion of the gripping device 300. The number of the clamping mechanisms 302 is but not limited to nine. The nine clamping mechanisms 302 are arranged in a rectangular array. Each clamping mechanism 302 can simultaneously grab four rows and four columns, a total of sixteen square bait cakes 1. In this way, the grabbing device 300 grabs three material grids 206, a total of one hundred and forty-four square bait cakes 1 each time.
