[0025] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0026] Embodiment 1:
[0027] See Figures 1-4, an egg tray stacking device, comprising a horizontally arranged base 1. A conveying structure 2 is arranged at the front end of the base 1. The front end of the conveying structure 2 is the loading end, and the rear end is the unloading end. The loading end of the conveying structure 2 is used to receive the egg trays that are horizontally placed on the conveying structure 2 after being demolded by an egg tray demolding machine. The conveying structure 2 includes a conveying frame 21 and two horizontal conveyors 22 arranged on the conveying frame 21. The two conveyors 22 are parallel to each other and are installed longitudinally. A certain spacing is reserved between the two horizontal conveyors 22. The bottom sides of the two sides of the conveyed egg trays are horizontally supported and synchronously conveyed by the two horizontal conveyors 22. A flipping unloading plate 3 is arranged at the unloading ends of the two conveyors 22. The flipping unloading plate 3 is located between the two conveyors 22. A rotating rod 31 is arranged at the bottom of the flipping unloading plate 3. A vertical column 32 is arranged on the base 1 below the rotating rod 31. The upper end of the rotating rod 31 is fixedly connected to the bottom of the flipping unloading plate 3, and the lower end is rotatably connected to the upper end of the vertical column 32. A first telescopic rod 33 is arranged on the vertical column 32. The fixed end of the first telescopic rod 33 is hinged to a first hinge seat arranged on the side wall of the vertical column 32, and the telescopic end of the first telescopic rod 33 is hinged to a second hinge seat arranged on the side wall of the rotating rod 31. A stacking mechanism 4 for stacking the egg trays 100 is arranged at the rear end of the base 1. The egg trays 100 are conveyed to the flipping unloading plate 3 by the two conveyors 22. The flipping unloading plate 3 is driven by the first telescopic rod 33 to flip the egg trays 100 from the horizontal state to the vertical state. Then, the stacking mechanism 4 quickly nests and neatly stacks the egg trays 100 to be stacked together, reducing the occupied space of the egg trays 100 and facilitating the overall handling of the egg trays 100. The stacking process of the egg trays is fully automated, saving the labor intensity of workers and having a high stacking efficiency of the egg trays.
[0028] In this embodiment, refer to Figure 1, the stacking mechanism 4 includes a push plate 41, a motor 42, a lead screw 43, a nut block 44, a lead screw base 45, and a moving crossbeam 46. Two lead screws 43 are symmetrically arranged on both sides of the base 1. One end of each lead screw 43 is provided with a motor 42 for driving the rotation of the lead screw 43. The other end of the lead screw 43 is rotationally supported by the lead screw base 45 provided on the base 1. The motor 42 and the lead screw 43 are horizontally arranged on the side of the base 1. The bracket of the motor 42 is fixed to the side of the base 1 by screws. The output shaft of the motor 42 is coaxially and fixedly connected to the driving end of the lead screw 43 through a coupling, so that the motor 42 can drive the lead screw 43 to rotate coaxially and synchronously. Two nut blocks 44 are arranged on the two lead screws 43, and a moving crossbeam 46 is arranged on the two nut blocks 44. The moving crossbeam 46 is horizontally arranged above the base 1, and a vertically arranged push plate 41 is arranged on the moving crossbeam 46. By driving the lead screw 43 to rotate through the motor 42, the rotation of the lead screw 43 drives the nut block 44 to move, and the movement of the nut block 44 drives the moving crossbeam 46 to move longitudinally along the guide above the base 1. When the motor 42 rotates clockwise, the push plate 41 can be driven away from the discharge end of the conveying structure 2. When the motor 42 rotates counterclockwise, the push plate 41 can be driven close to the discharge end of the conveying structure 2. The unloaded egg trays are nested and fixed on the egg trays on the push plate 41 and move together with the push plate 41, which can reserve positions for other egg trays to be stacked, saving space. At the same time, the egg trays after demoulding can be quickly fixed together without manual operation. The stacking process of the egg trays is fully automated, with a high degree of automation, saving labor costs and reducing labor intensity.
[0029] In this embodiment, referring to Figure 2 , 4 , a groove 34 is provided on the turning discharge plate 3. The shape of the groove 34 is rectangular. An activity plate 35 is arranged in the groove 34. When it is not necessary to unload the turning discharge plate 3, the activity plate 35 is retracted into the groove 34. When it is necessary to unload the turning discharge plate 3, the activity plate 35 is moved out of the groove 34 and acts on the egg trays for discharging. A second telescopic rod 36 for driving the movement of the activity plate 35 is arranged at the bottom of the turning discharge plate 3. The second telescopic rod 36 is an electric push rod.
[0030] In this embodiment, referring to Figure 1 , 2, 3, and 4. The tipping discharge plate 3 is flipped to make a thin plate with a certain thickness. The upper surface of the tipping discharge plate 3 needs to be at the same height as the upper surface of the conveyor belt of the conveyor 22, so that the egg trays conveyed on the conveyor belt of the conveyor 22 can be horizontally and smoothly transferred to the tipping discharge plate 3. A laterally distributed stop block 30 is provided at the front end of the tipping discharge plate 3 to prevent the egg trays unloaded onto the tipping discharge plate 3 from directly falling off the tipping discharge plate 3. Since the egg trays conveyed on the conveyor 22 have a certain inertia, they are likely to fall off the tipping discharge plate 3. Through the stop block 30, the egg trays can be more stably unloaded onto the tipping discharge plate 3, and the stability during the unloading process is good.
[0031] In this embodiment, referring to Figure 1 , 2 , a plurality of egg tray bodies 40 distributed in a dot array are provided on the side surface of the push plate 41. Generally, thirty egg tray bodies 40 are provided for an egg tray for thirty eggs. The egg tray bodies 40 are used to fix the egg tray 100. On the one hand, the egg tray 100 is buckled on the push plate 41 for positioning, and on the other hand, the egg tray 100 is prevented from shifting laterally.
[0032] In this embodiment, the motor 42 is a servo motor, and the forward and reverse rotation of the driving motor 42 can be realized through the driver control, which is convenient for driving the push plate 41 to move forward or backward.
[0033] In this embodiment, referring to Figure 1 , 3 , a plurality of horizontal guide rods 461 are provided on the side surface of the moving cross beam 46. Guide holes 301 are provided on the stop blocks 30 opposite to the guide rods 461. Through the guide rods 461, the egg trays 100 on the egg tray bodies 40 transferred to the push plate 41 can be supported, preventing the egg trays 100 embedded in the egg tray bodies 40 and the nested egg trays 100 from dropping, which affects the stable nesting of the egg trays 100 to be stacked on the fixed egg trays 100 on the push plate 41 by the tipping discharge plate 3. In addition, by providing the guide holes 301 on the stop blocks 30, the interference between the guide rods 461 and the tipping discharge plate 3 when bearing the egg trays 100 to be stacked is prevented, increasing the running smoothness of the tipping discharge plate 3, reducing the failure rate of the equipment, and increasing the stability of the equipment.
[0034] As can be seen from the above technical solution, during use, the demolded egg tray 100 is horizontally placed on the two conveyors 22. The two conveyors 22 are used to convey the egg tray 100 to the flipping discharge plate 3. The first telescopic rod 33 is used to drive the flipping discharge plate 3 to flip the egg tray 100 from the horizontal state to the vertical state. The controller is used to control the motor 42 to rotate counterclockwise, driving the push plate 41 to approach the discharge end of the conveying structure 2, and nesting and fixing the unloaded egg trays on the egg trays on the push plate 41. The controller is used to control the motor 42 to rotate clockwise, driving the push plate 41 away from the discharge end of the conveying structure 2, and driving the stacked egg trays 100 to move together with the push plate 41, so as to reserve positions for other egg trays to be stacked.
