Description

Technical Field

[0001] The present application relates to the technical field of packaging, and in particular to a material sorting device. Background Art

[0002] A tray is a box used for packaging. After the tray is filled with food or other materials and packaged and sealed, the trays that have completed material packaging are sorted or sorted to facilitate the subsequent palletizing of the trays by mechanical claws in the palletizing equipment.

[0003] In the related technology, the material sorting equipment includes a base and a conveyor belt, the conveyor belt is rotatably connected to the base, and a material diverting mechanism is provided on the conveyor belt. The material diverting mechanism includes a moving structure and a material diverting plate. The moving structure is arranged on the base, and the material diverting plate is arranged on the moving structure. The moving structure drives the material diverting plate to move the tray in the conveyor belt into the grabbing range of the mechanical claw in the stacking equipment.

[0004] When the trays are placed on the conveyor belt, there is a gap between two adjacent trays or two adjacent trays conflict with each other. If there is a gap between two adjacent trays, when the trays are placed on the conveyor belt, the number of trays within the moving range of the material shifting plate is difficult to determine, and the material shifting plate may push fewer trays than the stacking number to move during the movement, affecting the normal operation of the subsequent stacking mechanism; if two adjacent trays conflict with each other, the mechanical claws in the stacking mechanism may drive the excess trays to move, resulting in the problem of other trays being moved when the mechanical claws in the stacking mechanism grab them. Summary of the invention

[0005] In order to improve the problem that the trays in the conveyor belt may conflict with each other or be difficult to accurately position, the present application provides a material sorting device.

[0006] The present application provides a material sorting device, which adopts the following technical solution:

[0007] A material sorting equipment comprises a base and a conveyor belt, the conveyor belt is rotatably connected to the base, a limiting mechanism and a material shifting mechanism are provided on the base, the limiting mechanism is used to realize the mutual abutment of the trays, the material shifting mechanism is used to realize the separation of different groups of trays, the material shifting mechanism comprises a pushing structure and a separation structure, the pushing structure comprises a moving assembly and a first pushing member, the first pushing member is arranged on the moving assembly, the moving assembly drives the trays to separate from the conveyor belt through the first pushing member, the separation structure is used to drive different groups of trays to separate, the separation structure comprises a separation rod and a separation driving member, the separation rod is slidably connected to the base, the separation rod is located between two adjacent groups of trays, and the separation driving member drives the separation rod to move.

[0008] By adopting the above technical solution, the tray is limited by the limiting mechanism, so that the tray can stop moving on the conveyor belt, so that subsequent trays can conflict with each other, avoiding the situation where a gap appears between two adjacent trays, so as to facilitate the positioning of the trays; the first pushing member is driven by the moving component to separate the tray from the conveyor belt, and the separation structure separates the trays, so that different groups of trays can be separated, so that the mechanical claws of the subsequent stacking mechanism can grab the trays, so that the trays can be better stacked, and the accuracy of the mechanical claws in the stacking mechanism to grab the trays is improved; the separation rod is located between two adjacent groups of trays, and the separation drive member drives the separation rod to move, so that the separation rod separates the two adjacent groups of trays, so that the two adjacent groups of trays can be separated for the convenience of grabbing by the mechanical claws in the subsequent stacking mechanism.

[0009] Optionally, a separation plate is provided on the separation drive member, and the separation plate moves in a direction in which the tray is separated from the conveyor belt. The separation rod is slidably connected to the separation plate, and the separation rod moves in a transport direction of the conveyor belt.

[0010] By adopting the above technical solution, the separation plate is driven to move by the separation driving member, the separation plate moves in the direction in which the tray is separated from the conveyor belt, and the separation rod moves along the transportation direction of the conveyor belt. When the separation plate moves, the separation plate can drive the separation rod to move, so that the separation rod can separate different groups of trays.

[0011] Optionally, a dovetail hole is formed on the separation plate, a frame is formed on the base, a dovetail bar for passing through the dovetail hole is formed on the frame, and the dovetail bar extends along the transport direction of the conveyor belt.

[0012] By adopting the above technical solution, the separation plate slides on the dovetail bar, and the base can limit the moving direction of the separation plate, thereby increasing the sliding stability of the separation plate, so that the separation plate can stably drive the separation rod to move.

[0013] Optionally, two side panels are provided on the base, and the separation structure is located between the two side panels.

[0014] By adopting the above technical solution, the separation structure is located between the two side plates. When the separation rod drives the tray to move, the tray is limited by the side plates, so that the tray is not easy to move excessively, which makes it difficult for the tray to be positioned by the stacking mechanism.

[0015] Optionally, the limiting mechanism includes a limiting driving member and a rotating bar, and the limiting driving member drives the rotating bar to be inserted between two adjacent trays; when the rotating bar is located between two adjacent trays, the trays are limited from moving along the transport direction of the conveyor belt.

[0016] By adopting the above technical solution, the rotating bar is driven by the limit driving member to be inserted between two adjacent trays, so that the rotating bar can limit the movement of the tray, so that the conveyor belt can no longer drive the tray to move, and the tray is limited to move along the conveyor belt transportation direction.

[0017] Optionally, the limiting mechanism includes a rotating driving member and a rotating roller, the rotating roller abuts against the tray, the rotating driving member is arranged on the base, and the rotating roller is arranged on the rotating driving member; when the rotating roller rotates along the transport direction of the conveyor belt, the tray can move; when the rotating roller stops rotating or rotates in the opposite direction, the tray stops moving.

[0018] By adopting the above technical solution, the rotating roller is driven to rotate along the conveying direction of the conveyor belt by the rotating driving member, and the rotating roller can abut the tray, so that the rotating roller applies a force to the tray along the conveying direction of the conveyor belt, so that when the rotating roller rotates, it can drive the tray to move on the conveyor belt, allowing the tray to pass through the conveyor belt smoothly; when the rotating roller does not rotate or the rotating roller is reversed, the rotating roller abuts the tray, making it difficult for the tray to move on the conveyor belt, so that the subsequent tray can abut the tray, so that the subsequent trays can contact each other, so as to facilitate the positioning of the tray.

[0019] Optionally, a stop plate is provided on the base, and the stop plate is located on the moving path of the tray. When the tray abuts against the stop plate, the pushing structure can drive the tray to move.

[0020] By adopting the above technical solution, the stop plate is located on the moving path of the tray, so that the stop plate limits the movement of the tray; when the tray abuts the stop plate, the pushing structure can drive the tray to separate from the conveyor belt, preventing the tray from continuing to move and causing part of the tray to separate from the pushing range of the pushing structure.

[0021] Optionally, a stop bar is slidably connected to the stop plate, an elastic ring is slidably connected to the rotating roller, and a linkage assembly is provided on the rotating roller; when the tray abuts against the stop bar, the stop bar drives the elastic ring to abut against the tray through the linkage assembly, and the tray stops moving at this time.

[0022] By adopting the above technical scheme, when the tray moves on the conveyor belt, the tray can abut against the stop bar, and the stop bar drives the elastic ring to move through the linkage component, so that the elastic ring can protrude from the rotating roller, so that the elastic ring abuts against the tray, and the tray stops moving, thereby preventing the conveyor belt from continuing to drive the tray to move. When the pushing structure moves the tray, subsequent trays are allowed to collide with each other to facilitate the positioning of subsequent trays. When subsequent trays collide with each other, the time for the pushing structure to move the tray can be used to further improve the material sorting speed of the material sorting equipment.

[0023] Optionally, the linkage assembly includes a linkage bar and a linkage block. The linkage bar is slidably connected to the rotating roller. The linkage block is disposed on the stop bar. A linkage inclined surface is formed on the linkage block. The distance between the linkage inclined surface and the elastic ring gradually decreases in the direction from the stop plate to the linkage block. The linkage inclined surface is located on the driving path of the linkage bar. When the tray abuts against the stop bar, the stop bar drives the linkage bar to move through the linkage inclined surface. At this time, the linkage bar drives the elastic ring to abut against the tray.

[0024] By adopting the above technical solution, when the stop bar moves, the stop bar drives the linkage block to move. Since the linkage inclined surface is located on the driving path of the linkage bar, and the distance between the linkage inclined surface and the elastic ring gradually decreases in the direction from the stop plate to the linkage block, the linkage inclined surface can drive the linkage bar to move, enabling the linkage bar to abut against the protruding elastic ring, and realizing the elastic ring abutting against the tray.

[0025] Optionally, a receiving plate is provided on the base. A receiving hole for the separating rod to slide through is formed on the receiving plate, and a plurality of receiving holes are provided. When the pushing structure abuts against the separating rod, the separating rod separates the tray along the direction of the receiving hole.

[0026] By adopting the above technical solution, the receiving plate is provided on the base, allowing the separating rod to pass through the receiving hole. When the pushing structure moves, the pushing structure abuts against the separating rod, causing the separating rod to move along the direction of the receiving hole, enabling the separating rod to drive the tray to separate, and realizing the separation of adjacent two groups of trays. The staff only needs to replace the receiving plate, enabling the separating rod to pass through different receiving holes, so that the separating rod can drive different groups of trays to separate, facilitating the staff to separate different groups of trays.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The tray is limited by the limiting mechanism, enabling the tray to stop moving on the conveyor belt, so that subsequent trays can abut against each other, avoiding the situation of gaps between adjacent two trays, and facilitating the positioning of the trays. The pushing structure disengages the tray from the conveyor belt, and the separating structure separates the trays, realizing the separation of different groups of trays, facilitating the mechanical claw of the subsequent palletizing mechanism to grab the trays, thereby enabling the trays to be better palletized and improving the accuracy of the mechanical claw in grabbing the trays in the palletizing mechanism. The separating rod is located between adjacent two groups of trays, and the separating driving member drives the separating rod to move, realizing the separation of the separating rod from adjacent two groups of trays, enabling adjacent two groups of trays to be separated for the subsequent grabbing by the mechanical claw in the palletizing mechanism.

[0029] 2. The rotating roller is driven to rotate along the conveying direction of the conveyor belt by a rotating driving member, and the rotating roller can abut against the tray, so that the rotating roller applies a force to the tray along the conveying direction of the conveyor belt, so that when the rotating roller rotates, it can drive the tray to move on the conveyor belt, allowing the tray to pass through the conveyor belt smoothly; when the rotating roller does not rotate or the rotating roller is reversed, the rotating roller abuts against the tray, making it difficult for the tray to move on the conveyor belt, so that the subsequent tray can abut against the tray, so that the subsequent trays can contact each other, so as to facilitate the positioning of the tray.

Referring to Figure 1 , a material sorting device includes a base 1 and a conveyor belt 11, and the conveyor belt 11 is rotatably connected to the base 1. There are two material pushing mechanisms 2 and two limiting mechanisms 3 provided on the base 1. The material pushing mechanism 2 is used to push the trays, so that adjacent two groups of trays are separated from the conveyor belt and adjacent two groups of trays are separated from each other. The limiting mechanism 3 is used to limit the trays on the conveyor belt 11, so that the trays on the conveyor belt 11 can abut against each other.

[0048] Referring to Figure 1, a mounting plate 12 is fixedly connected to the base 1. The mounting plate 12 is located on the side of the base 1 away from the ground, and the material feeding mechanism 2 is arranged on the mounting plate 12. The limiting mechanism 3 and the material feeding mechanism 2 are arranged in sequence along the transportation direction of the conveyor belt 11.

[0049] Referring to Figure 2 , the limiting mechanism 3 includes a rotating roller 31 and a rotation driving member 32. The rotation driving member 32 includes a first motor. The driving shaft of the first motor is fixedly connected to the rotating roller 31.

The rotating roller 31 is rotatably connected to the rotating frame 13, and the first motor is fixedly connected to the rotating frame 13. A placing plate 131 is fixedly connected to the base 1. A plurality of threaded holes 132 are formed in the placing plate 131. A plurality of strip-shaped holes 133 are formed in the rotating frame 13. The strip-shaped holes 133 extend in the vertical direction. A placing bolt 134 is provided on the rotating frame 13. The placing bolt 134 is threadedly connected to the threaded hole 132 through the strip-shaped hole 133 to realize the mutual fixation of the rotating frame 13 and the placing plate 131. The staff changes the distance between the rotating frame 13 and the conveyor belt 11 by placing the bolt 134 at different positions in the strip-shaped hole 133.

[0051] Referring to Figure 2 and Figure 3 , a rubber layer 311 is fixedly connected to the rotating roller 31. The rubber layer 311 has flexibility and is made of rubber. The rubber layer 311 and the rotating roller 31 are fixedly connected by bolts. When the tray is located on the conveyor belt 11, the rubber layer 311 abuts against the tray; if the rotating roller 31 rotates along the transportation direction of the conveyor belt 11, the rubber layer 311 drives the tray to move on the conveyor belt 11; if the rotating roller 31 does not rotate or rotates in reverse, the rubber layer 311 abuts against the tray to limit the movement of the tray on the conveyor belt 11.

[0052] Referring to Figure 2 , a positioning structure 4 is fixedly connected to the base 1. The positioning structure 4 includes two first positioning strips 41 and two second positioning strips 42. Both of the two first positioning strips 41 are located on the side of the conveyor belt 11 away from the ground. The two second positioning strips 42 are respectively located on different sides of the tray, and the second positioning strip 42 can limit the tray from separating from the conveyor belt 11. The end face of the first positioning strip 41 is inclined away from the ground, and the end face of the second positioning strip 42 is inclined away from the other second positioning strip 42 to facilitate the tray to be limited by the first positioning strip 41 and the second positioning strip 42.

[0053] Referring to Figure 4, the blanking mechanism 2 includes a pushing structure 21 and a separating structure 22. The pushing structure 21 is used to move the tray to the mounting plate 12, and the separating structure 22 separates two adjacent groups of trays. The pushing structure 21 includes a moving component, a first pushing member, and a second pushing member. The moving component includes a lateral pushing component 23 and a longitudinal pushing component 24. Both the first pushing member and the second pushing member are pushing plates.

The transverse plate 241 is fixedly connected to the lateral moving belt 232, and the longitudinal cylinders 242 are fixedly connected to the lateral moving belt 232. Two pushing plates 25 are respectively fixedly connected to the drive shafts of different longitudinal cylinders 242, and the two pushing plates 25 are distributed in a direction perpendicular to the conveyor belt 11. The lateral moving belt 232 can drive the transverse plate 241 to move horizontally, and the longitudinal cylinders 242 can drive the pushing plates 25 to move vertically.

[0055] Referring to Figure 4 , the longitudinal cylinder 242 drives the pushing plate 25 to drop, and the lateral pushing component 23 drives the pushing plate 25 to move horizontally, so that the pushing plate 25 abuts against the tray. One pushing plate 25 moves the tray from the conveyor belt 11 to the mounting plate 12, and at this time the tray moves to the waiting area; at the same time, the other pushing plate 25 moves the tray from the waiting area to the grasping area, and at this time the tray is separated by the separating structure 22; the longitudinal cylinder 242 drives the pushing plate 25 to move, the pushing plate 25 disengages from the tray, and then the lateral pushing component 23 drives the pushing plate 25 to move to realize the reset of the pushing plate 25.

[0056] Referring to Figure 4 , a pushing strip 251 is provided on the pushing plate 25, and the pushing strip 251 is located on the side of the tray away from the ground. A plurality of pushing blocks 252 are bolted to the pushing strip 251, and the pushing blocks 252 are used to prevent the tray from moving horizontally during the movement. A plurality of pushing blocks 252 are bolted to the pushing plate 25 to realize the mutual fixation of the pushing strip 251 and the pushing plate 25.

[0057] Referring to Figure 4 and Figure 5 , a plurality of photoelectric sensors 14 are fixedly connected to the base 1, and the photoelectric sensors 14 are electrically connected to the pushing structure 21. When the plurality of photoelectric sensors 14 all detect the tray, the pushing structure 21 moves the tray from the conveyor belt 11 to the base 1. The photoelectric sensors 14 are blocked by the protection plate 141, and the protection plate 141 protects the photoelectric sensors 14.

[0058] Referring to Figure 4 and Figure 6 Figure 6 , two side plates 15 are provided on the base 1. Between the two side plates 15, a tray can move, and the separation structure 22 is located between the two side plates 15. The separation structure 22 includes a separation driving member 28 and a plurality of separation rods 27. The separation rods 27 are located between adjacent groups of trays, enabling the separation rods 27 to drive the trays to move. The separation driving member 28 is used to drive the separation rods 27 to move, realizing the separation of adjacent groups of trays.

[0059] Referring to Figure 4 Figure 4 , a side strip 151 is provided on the side plate 15. Two waist-shaped holes 152 are opened on the side strip 151, and the waist-shaped holes 152 extend along the length direction of the conveyor belt 11. A side bolt is provided on the side strip 151, and the side bolt is inserted into the waist-shaped hole 152 to realize the movement of the position of the side plate 15.

[0060] Referring to Figure 4 and Figure 6 Figure 6 , the separation driving member 28 includes a separation cylinder. A frame 16 is fixedly connected to the base 1, and the separation cylinder is fixedly connected to the frame 16. A separation plate 26 is fixedly connected to the driving shaft of the separation cylinder. A plurality of separation blocks 261 are slidably connected to the separation plate 26. The separation plate 26 moves along the transportation direction of the transverse moving belt 232, and the separation blocks 261 move along the transportation direction of the conveyor belt 11. A receiving block 265 is fixedly connected to the surface of the separation block 261. A receiving hole 266 for the receiving block 265 to be inserted is opened on the separation plate 26. A plurality of receiving holes 266 are provided, and the plurality of receiving holes 266 are arranged in an array along the length direction of the separation plate 26. The receiving hole 266 is inclined between the transportation direction of the transverse moving belt 232 and the direction away from another receiving hole 266. The receiving block 265 can slide in the receiving hole 266 to realize the sliding of the separation block 261 on the separation plate 26.

[0061] Referring to Figure 4 and Figure 6 Figure 6 , a separation hole 262 is opened on the surface of the separation block 261, and the separation rod 27 is inserted into the separation hole 262. A separation nut 263 is threadedly connected to the separation rod 27. The separation rod 27 is inserted into the separation hole 262, and the separation nut 263 is located on the side of the separation block 261 away from the ground, fixing the separation rod 27 to the separation block 261. A separation moving hole 264 is opened on the mounting plate 12, and the separation rod 27 passes through the separation moving hole 264. The separation moving hole 264 extends along the length direction of the pushing plate 25.

[0062] Referring to Figure 4 and Figure 6, when the separation cylinder is started, the separation cylinder drives the separation plate 26 to move. The separation plate 26 drives the separation block 261 to move through the accommodation block 265. In addition, the separation rod 27 is limited by the separation movement hole 264, so that the separation block 261 moves along the length direction of the separation movement hole 264, enabling the separation rod 27 to push the adjacent tray to move and realizing the separation of the adjacent trays.

[0063] The implementation principle of Embodiment 1 is as follows: The trays move through the conveyor belt 11. When the rotating motor is turned off or reversed, the rotating roller 31 stops rotating or rotates in the direction opposite to the transportation direction of the conveyor belt 11, so that the trays on the conveyor belt 11 can abut against each other. Then the rotating motor is turned on, the rotating roller 31 rotates in the transportation direction of the conveyor belt 11, the rotating roller 31 drives the trays through the conveyor belt 11, the transverse pushing assembly 23 and the longitudinal pushing assembly 24 drive the two pushing plates 25 to move, so that one pushing plate 25 moves a group of trays from the conveyor belt 11 to the waiting area, and the other pushing plate 25 moves another group of trays from the waiting area to the grasping area. At this time, the separation cylinder drives the separation rod 27 to move through the separation plate 26, so that the separation rod 27 drives the trays to move and realizes the separation of the adjacent two groups of trays.

[0064] Embodiment 2

[0065] Refer to Figure 7 , the difference between this embodiment and Embodiment 1 is that the separation rod 27 is fixedly connected to the mounting plate 12, and two separation inclined surfaces 271 are provided on the surface of the separation rod 27. In other embodiments, the separation rod 27 can also be provided with an arc surface, and the inclination angle of the arc surface is the same as the inclination angle of the separation inclined surface 271. The distance between the separation inclined surface 271 and the side plate 15 gradually decreases along the direction from the pushing plate 25 to the separation rod 27, and the separation inclined surface 271 is located on the movement path of the tray. When the pushing plate 25 abuts against the tray, the separation rod 27 separates the tray through the separation inclined surface 271, so that the tray is located between two adjacent trays.

[0066] Embodiment 3

[0067] Refer to Figure 8 , the difference between this embodiment and Embodiment 1 is that the limiting mechanism 3 includes a conveyor belt 33. The tray is located between the conveyor belt 33 and the conveyor belt 11, and the conveyor belt 33 can abut against the surface of the tray away from the conveyor belt 11. A sponge layer is provided on the conveyor belt 33, and the sponge layer can abut against the tray.

[0068] Refer to Figure 8 , a moving structure 331 is provided on the base 1. The moving structure 331 is used to move the conveyor belt 33 and control the distance between the conveyor belt 33 and the conveyor belt 11, so that the conveyor belt 33 can abut against the tray. In this embodiment, the moving structure 331 can be a moving cylinder or other structures.

[0069] Example 4

[0070] Reference Figure 9 In this example, the difference from Example 1 is that the limiting mechanism 3 includes a limiting driving member 34 and a rotating bar 35. The limiting driving member 34 includes a limiting air cylinder which is fixedly connected to the base 1. A rotating block 341 is rotatably connected to the driving shaft of the limiting air cylinder, and the rotating bar 35 is fixedly connected to the rotating block 341. The limiting air cylinder drives the rotating bar 35 to be inserted into the moving path of the tray, so that the rotating bar 35 restricts the movement of the tray on the conveyor belt 11.

[0071] Example 5

[0072] Reference Figure 10 In this example, the difference from Example 1 is that a stop plate 5 is provided on the base 1, and the stop plate 5 is located on the moving path of the tray. When the tray abuts against the stop plate 5, the tray is detected by the photoelectric sensor 14. One end of the conveyor belt 11 where the tray is placed is the entrance, and the stop plate 5 is located on the side of the two limiting mechanisms 3 away from the entrance.

[0073] Reference Figure 10 A groove 51 is formed in the stop plate 5, and the groove 51 penetrates to the side surface of the stop plate 5. A stop spring 511 is fixedly connected to the bottom wall of the groove 51, and a stop bar 512 is fixedly connected to the surface of the stop spring 511 away from the bottom wall of the groove 51. The stop bar 512 is located on the moving path of the tray. When the stop bar 512 is located in the groove 51, the stop spring 511 is in a compressed state; when the stop bar 512 protrudes from the groove 51, the stop spring 511 is in a non-loaded state. A stop block 513 is integrally formed on the stop bar 512, and the stop block 513 extends along the length direction of the conveyor belt 11.

[0074] Reference Figure 11 An arc-shaped hole 52 is formed on the outer surface of the rotating roller 31, and the arc-shaped hole 52 penetrates to the rubber layer 311. An elastic ring 521 is slidably connected in the arc-shaped hole 52, and the elastic ring 521 has the ability of elastic deformation. When the elastic ring 521 is completely located in the arc-shaped hole 52, the elastic ring 521 is in a non-loaded state; when the elastic ring 521 protrudes from the rubber layer 311 and abuts against the tray, the elastic ring 521 is in a stretched state, and at this time the elastic ring 521 restricts the movement of the tray on the conveyor belt 11.

[0075] Reference Figure 11, a linkage assembly 53 is provided on the rotating roller 31, and the linkage assembly 53 is used to abut against the elastic ring 521. The linkage assembly 53 includes a linkage bar 531 and a linkage block 532. A linkage groove 54 is formed on the end face of the rotating roller 31, and a linkage spring 541 is fixedly connected to the bottom wall of the linkage groove 54. The surface of the linkage spring 541 away from the bottom wall of the linkage groove 54 is fixedly connected to the linkage bar 531. When the linkage bar 531 protrudes from the linkage groove 54, the linkage spring 541 is in a non-loaded state; when the linkage bar 531 abuts against the elastic ring 521 and the elastic ring 521 protrudes from the rubber layer 311, the linkage spring 541 is in a compressed state.

[0076] Refer to Figure 10 and Figure 11 , the linkage block 532 is fixedly connected to the surface of the stop block 513 facing the rotating roller 31, and a linkage inclined surface 533 is formed on the linkage block 532. The distance between the linkage inclined surface 533 and the stop block 513 gradually increases along the direction from the stop bar 512 to the linkage block 532, and the linkage inclined surface 533 is located on the moving path of the linkage bar 531.

[0077] Refer to Figure 11 , when the tray abuts against the stop bar 512, the stop bar 512 drives the linkage block 532 to move, so that the linkage block 532 drives the linkage bar 531 to move through the linkage inclined surface 533, and the linkage bar 531 drives the elastic ring 521 to abut against the tray, making it difficult for the tray to move on the conveyor belt 11.

[0078] Refer to Figure 12 , a through hole 61 is formed on the surface of the mounting plate 12, and a receiving plate 6 is provided on the base 1. The receiving plate 6 can be located in the through hole 61, and the receiving plate 6 and the mounting plate 12 are fixedly connected by bolts. A receiving hole 62 for the separation rod 27 to slide is formed on the receiving plate 6, and two receiving holes 62 are formed. The receiving hole 62 inclines away from the pushing plate 25 and the receiving hole 62 inclines away from the other receiving hole 62, and the receiving hole 62 extends along the length direction perpendicular to the pushing plate 25.

[0079] Refer to Figure 12 and Figure 13 , a receiving groove 63 is formed on the base 1, and four receiving blocks 631 are slidably connected in the receiving groove 63. The separation driving member 28 includes four return springs, and each return spring is respectively fixedly connected to a different receiving block 631. The surface of the return spring away from the receiving block 631 is fixedly connected to the groove wall of the receiving groove 63.

[0080] Refer to Figure 12 and Figure 13, a receiving spring 632 is fixedly connected to the surface of the receiving block 631 away from the bottom wall of the receiving groove 63, and the surface of the receiving spring 632 away from the receiving block 631 is fixedly connected to the separating rod 27. When the separating rod 27 passes through the receiving hole 62, the receiving spring 632 is in an unloaded state; when the separating rod 27 is completely located in the receiving groove 63, the receiving spring 632 is in a compressed state. When the separating rod 27 abuts against the hole wall of the receiving hole 62 on the side facing the conveyor belt 11, the return spring is in an unloaded state; when the separating rod 27 abuts against the hole wall of the receiving hole 62 away from the conveyor belt 11, the return spring is in a stretched state.

[0081] Referring to Figure 12 and Figure 13 , when the pushing plate 25 moves the tray, the pushing plate 25 abuts against the separating rod 27. At this time, the pushing plate 25 pushes the separating rod 27 to move in the receiving hole 62, realizing the separation of different groups of trays by the separating rod 27. When the pushing plate 25 does not abut against the tray, the return spring drives the receiving block 631 to reset.

[0082] Referring to Figure 14 , a mounting strip 64 is fixedly connected to the surface of the receiving plate 6, and a mounting groove 641 for inserting the mounting strip 64 is formed on the surface of the mounting plate 12, and the mounting groove 641 extends along a direction perpendicular to the transportation direction of the conveyor belt 11. When the receiving plate 6 is mounted on the mounting plate 12, the mounting strip 64 is located in the mounting groove 641.

[0083] Referring to Figure 14 , a dovetail block 642 is fixedly connected to the surface of the mounting strip 64, and a dovetail groove 65 for inserting the dovetail block 642 is formed on the surface of the stop plate 5, and the dovetail groove 65 extends in the vertical direction. When the stop plate 5 is mounted on the base 1, the stop plate 5 can be inserted into the mounting groove 641, and then the worker inserts the dovetail block 642 into the dovetail groove 65 to realize the mutual fixation of the mounting strip 64 and the stop plate 5.

[0084] Referring to Figure 14 , a baffle 66 is slidably connected to the mounting plate 12, and the baffle 66 can block the opening of the mounting groove 641. When the baffle 66 blocks the opening of the mounting groove 641, the baffle 66 restricts the mounting strip 64 from disengaging from the mounting groove 641. At this time, the mounting strip 64 is mounted on the base, and the stop plate 5 is mounted on the base.

[0085] The implementation principle of Embodiment 5 is as follows: when the tray abuts against the stop bar 512, the stop bar 512 drives the linkage bar 531 to move through the linkage inclined surface 533, so that the linkage bar 531 drives the elastic ring 521 to abut against the tray, restricting the tray from continuing to move. The pushing structure 21 drives the pushing plate 25 to abut against the tray. At this time, the pushing plate 25 abuts against the separating rod 27 and moves, so that the separating rod 27 separates different groups of trays.
