[0038] Please also read Figures 1 to 5 Now, an automatic pallet sorting machine provided in the embodiment of the present application is described. The automatic pallet sorting machine comprises a frame 100, a material bin 101, a feeding device, a damping device and a material taking device. Among them:

[0039] The silo 101 is mounted on the frame 100 and includes a guard plate 102 arranged in parallel and at intervals. In some other embodiments of the present application, the guard plates 102 on both sides can also be arranged to be able to move closer to or farther from each other to adapt to blister trays 200 of different widths, which will not be described in detail here. The feeding device includes a push head 103 extending into the silo 101 and a feeding drive mechanism connected to the push head 103 in a transmission manner. The feeding drive mechanism is used to drive the push head 103 to move closer to or farther from the discharge port of the silo 101 in a direction parallel to the guard plate 102. The damping device includes a damping block 104 mounted on the guard plates 102 on both sides. The damping block 104 is located between the push head 103 and the discharge port of the silo 101. The damping block 104 forms a serrated surface 105 located in the silo 101 and inclined relative to the guard plate 102. The serrated surface 105 gradually moves toward the center of the silo 101 in the direction of the discharge port of the silo 101. The material picking device includes a suction cup 106 for picking up materials and a material picking driving mechanism which is transmission-connected to the suction cup 106 and used to drive the suction cup 106. The suction cup 106 is opposite to the discharge port of the silo 101 and is distributed on both sides of the damping block 104 with the push head 103. The moving direction of the suction cup 106 is parallel to the moving direction of the push head 103. The material picking device also includes a negative pressure pipe 107 which is connected to the suction cup 106 and used to provide negative pressure for the suction cup 106. A vent valve 108 is provided on the negative pressure pipe 107.

[0040] According to the above structure provided in this embodiment, since the damping block 104 forms a serrated surface 105 inclined relative to the guard plate 102 and the serrated surface 105 gradually approaches the center of the silo 101 in the direction of the discharge port of the silo 101, the multiple blister trays 200 pushed by the push head 103 can be embedded in the serrated surface 105 of the damping block 104 before escaping from the silo 101. In this way, the suction cup 106 arranged outside the silo 101 can suck the blister tray 200 from the discharge port of the silo 101 under the drive of the material taking drive mechanism. Since the blister trays 200 are stacked in the silo 101, the suction cup 106 can only adsorb the blister tray 200 abutting against the suction cup 106 during a single adsorption of the blister tray 200, while allowing other blister trays 200 to continue to stay in the silo 101 waiting for the next adsorption. In this way, not only can the trays stacked in the silo 101 be effectively separated, but also the blister trays 200 can be quickly and automatically extracted, with a tray separation efficiency far superior to that of the prior art. In addition, in this embodiment, a vent valve 108 is provided on the negative pressure tube 107 for providing negative pressure to the suction cup 106, which can quickly connect the suction cup 106 to the atmosphere and make the bubble cap tray 200 fall from the suction cup 106, which is conducive to further improving the tray separation efficiency of the automatic tray separation machine in this embodiment; here, it can be understood that the bubble cap tray 200 is formed by a PVC sheet and has a certain elasticity. Therefore, when the suction cup 106 sucks the bubble cap tray 200 at a single time, the suction cup 106 sucks the outermost bubble cap tray 200 and produces elastic deformation under the pulling of the material taking cylinder 125 so that its edge is detached from the serrated surface 105, and the next bubble cap tray 200 is still maintained at the current position due to not being subjected to the pulling force generated by the suction cup 106, thereby separating the bubble cap trays 200 one by one and completing the tray separation.

[0041] In another embodiment of the present application, please refer to Figures 1 to 5 , the damping block 104 is rotatably mounted on the guard plate 102 and the rotation center axis of the damping block 104 is parallel to the guard plate 102. According to the above structure provided in this embodiment, the inclination angle of the serrated surface 105 on the damping block 104 relative to the guard plate 102 can be adjusted by rotating the damping block 104 relative to the guard plate 102, so that the damping block 104 can better adapt to the blister trays 200 of different widths and form a stable limit for them, which is conducive to significantly expanding the application range of the automatic tray dispensing machine in this embodiment.

[0042] In another embodiment of the present application, please refer to Figures 1 to 5The damping device further includes a blocking bar 109 horizontally placed on the frame 100, and the blocking bar 109 abuts against the bottom end of the guard plate 102 for forming the discharge port of the silo 101. According to the above structure provided in this embodiment, the blocking bar 109 arranged on the frame 100 can cooperate with the damping block 104 to limit the bubble cap tray 200 in the silo 101, so as to better prevent the bubble cap tray 200 in the silo 101 from rushing out of the discharge port of the silo 101 under the push of the push head 103, which is conducive to making the automatic tray dispensing machine provided in this embodiment more stable to use.

[0043] In another embodiment of the present application, please refer to Figures 1 to 5 The damping device also includes a pressing plate 110 facing the bottom of the silo 101 and a pressing plate cylinder 111 connected to the pressing plate 110. The output direction of the pressing plate cylinder 111 is parallel to the depth direction of the silo 101. The pressing plate 110 forms a plurality of saw teeth arranged along the moving direction of the push head 103 on a side surface of the silo 101. According to the above structure provided in this embodiment, when the number of bubble cap trays 200 at the discharge port of the silo 101 is small, the pressing plate 110 can be in a lifting state, and when the number of bubble cap trays 200 at the discharge port of the silo 101 is large, the pressing plate 110 can be driven downward by the pressing plate cylinder 111 and form a limit for the subsequent bubble cap trays 200 to prevent the bubble cap trays 200 at the rear from continuing to move under the pushing action of the push head 103, which is conducive to maintaining a reasonable number of bubble cap trays 200 at the discharge port of the silo 101 and making the automatic tray separating machine provided in this embodiment run stably.

[0044] In another embodiment of the present application, please refer to Figures 1 to 5 The damping device further includes a photoelectric sensor 112 disposed at the end of the guard plate 102 and used to detect the target material. The photoelectric sensor 112 is also communicatively connected to the pressing plate cylinder 111 and enables the pressing plate 110 to be linked to the detection signal of the photoelectric sensor 112. According to the above structure provided in this embodiment, the photoelectric sensor 112 communicatively connected to the pressing plate cylinder 111 can transmit the quantity information of the blister trays 200 detected at the discharge port of the silo 101 to the pressing plate cylinder 111 and control the output of the pressing plate cylinder 111, which is conducive to further maintaining a reasonable number of blister trays 200 at the discharge port of the silo 101.

[0045] In another embodiment of the present application, please refer to Figures 1 to 5The damping device also includes an adjustment seat 113 connected to the guard plate 102 and capable of rising and falling along the depth direction of the silo 101, and the pressing plate cylinder 111 is installed on the adjustment seat 113. According to the above structure provided in this embodiment, the pressing plate cylinder 111 is arranged on the adjustment seat 113 so that the pressing plate 110 connected to the output end of the pressing plate cylinder 111 has a larger adjustment range in the height direction of the silo 101, which is conducive to adapting to more height sizes of blister trays 200 and further expanding the application range of the automatic tray separating machine in this embodiment.

[0046] In another embodiment of the present application, please refer to Figures 1 to 5 The material taking device further comprises an air blowing nozzle 114 connected to the adjusting seat 113 and a slideway 115 connected to the frame 100, the air blowing nozzle 114 is directly opposite to the feeding port of the slideway 115 and the feeding port of the slideway 115 is oriented orthogonal to the moving direction of the suction cup 106. According to the above structure provided in this embodiment, the air blowing nozzle 114 connected to the adjusting seat 113 can blow the bubble cap tray 200 adsorbed on the suction cup 106 into the slideway 115 more quickly, and the slideway 115 provided on the frame 100 can quickly transfer the bubble cap tray 200 to the target position, which is conducive to further improving the tray separation efficiency of the automatic tray separation machine in this embodiment.

[0047] In another embodiment of the present application, please refer to Figures 1 to 5 The feeding drive mechanism includes a guide rod 116 connected to the guard plate 102 and parallel to the moving direction of the push head 103, a moving seat 117 slidably connected to the guide rod 116, and a pulley 118 rotatably mounted on the guard plate 102. The push head 103 is connected to the moving seat 117, and a pull rope 119 that bypasses the pulley 118 is connected to the moving seat 117. The end of the pull rope 119 away from the moving seat 117 is connected to a freely hanging weight 120. According to the above structure provided in this embodiment, since the weight 120 connected to the pull rope 119 hangs freely, it can drive the moving seat 117 connected to the pull rope 119 to move on the guide rod 116, so that the push head 103 connected to the moving seat 117 can be stably moved in the material bin 101 in a predetermined direction, and has a good pushing effect. In addition, since the weight 120 provided in this embodiment uses its own gravitational potential energy to drive the push head 103 without external force, it can achieve a good energy-saving and emission-reduction effect, which is far superior to the conventional technology. It should be noted that the weight of the weight 120 needs to be flexibly set according to the damping effect of the damping block 104 to achieve the technical effect of preventing the blister tray 200 from rushing out of the discharge port of the silo 101 under the driving action of the push head 103.

[0048] In another embodiment of the present application, please refer to Figures 1 to 5The feeding drive mechanism further includes a conveyor belt 121 disposed at the bottom of the silo 101, and the conveying direction of the conveyor belt 121 is parallel to the moving direction of the push head 103. According to the above structure provided in this embodiment, when the number of blister trays 200 stacked in the silo 101 is large and the push head 103 cannot push the blister trays 200, the conveyor belt 121 can play a role in assisting the conveying of the blister trays 200, thereby facilitating the stable and smooth operation of the automatic tray dispensing machine provided in this embodiment.

[0049] In another embodiment of the present application, please refer to Figures 1 to 5 The material taking driving mechanism includes a support 122 connected to the frame 100, a horizontal movable seat 123 movably arranged on the support 122 and used for moving in the horizontal direction, and an upper and lower movable seat 124 movably arranged on the horizontal movable seat 123 and used for moving in the vertical direction. The material taking driving mechanism also includes a material taking cylinder 125 installed on the upper and lower movable seats 124 and transmission-connected to the suction cup 106. According to the above structure provided in this embodiment, through the horizontal movable seat 123 movably arranged on the support 122, the upper and lower movable seats 124 movably arranged on the horizontal movable seat 123, and the material taking cylinder 125 arranged on the upper and lower movable seats 124, the technical effect of flexibly adjusting the position of the suction cup 106 in space can be achieved, which is conducive to making the suction cup 106 more directly facing the discharge port of the silo 101 and further improving the tray sorting efficiency of the automatic tray sorting machine in this embodiment.
