Description

Technical Field

[0001] This utility model relates to the field of stacking technology for plastic boxes, and in particular to a stacking machine for plastic boxes. Background Technology

[0002] In the process of moving plastic boxes, in order to reduce the floor space occupied, the plastic boxes need to be stacked to facilitate subsequent transfer or packaging and storage.

[0003] Some plastic boxes are quite large, making manual handling of empty boxes difficult. The weight of the boxes after being filled with items further increases the difficulty of manual handling, necessitating the use of stacking equipment. In the prior art, utility model patent application number 202120221522X discloses a box stacking device that can automatically separate, rotate, and stack cartons; however, its complex structure makes it unsuitable for stacking plastic boxes and requires improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a stacking machine for plastic boxes, which simplifies the structure and improves the level of automation.

[0005] To achieve this objective, the present invention adopts the following technical solution: A stacking machine for plastic boxes includes: a frame, a conveyor, a flip plate, a controller, and bearing seats. The conveyor is horizontally and vertically mounted in the frame. The bearing seats are positioned opposite each other on both sides of the top opening of the frame. A rotating shaft is horizontally mounted in the bearing seats. The flip plate is mounted on the rotating shaft and points obliquely upward toward the top of the conveyor. The top two sides of the plastic box are provided with protruding ribs. The end of the flip plate is provided with clamps corresponding to the protruding ribs. The controller is connected to the conveyor for operation control.

[0006] The frame is vertically equipped with slide rails on both sides of the conveyor, and the slide rails are equipped with sliders that are connected to the sides of the conveyor.

[0007] The frame is equipped with a lifting drive mechanism for driving the conveyor to move up and down, and the controller is connected to the lifting drive mechanism to control the lifting.

[0008] The lifting drive mechanism is either an electric telescopic rod or a cylinder.

[0009] The flap is provided with a limit pin on one side. The limit pin rotates with the flap and limits the downward angle of the flap when it contacts the bearing seat.

[0010] The conveyor is a roller conveyor.

[0011] The frame has a crossbeam located above the edge of the conveyor on one side. Two displacement sensors are installed on the crossbeam at intervals. The displacement sensors are connected to the controller for signal transmission.

[0012] The beneficial effects of this utility model are as follows: A stacking machine for plastic boxes involves the preceding process equipment sending the plastic boxes onto a conveyor, which moves the plastic boxes to below a flip plate. The rising of the conveyor lifts the plastic boxes, causing the protruding ribs of the plastic boxes to contact the bottom surface of the flip plate, driving the flip plate to rotate upwards at an angle. When the height of the protruding ribs is higher than that of the clamping plates, the clamping plates are located below the protruding ribs and clamp the plastic boxes. The protruding ribs are used to limit the downward movement of the plastic boxes. Subsequent plastic boxes can be lifted in sequence to complete the stacking of plastic boxes. The machine has a high degree of automation, a simple structure, and low maintenance costs. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A three-dimensional image. Detailed Implementation

[0014] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] A stacking machine for plastic boxes 9 is provided for conveying and stacking plastic boxes 9. The machine includes a frame 1, a conveyor 2, a flip plate 5, a controller 10, and a bearing seat 4. The conveyor 2 is horizontally and vertically arranged in the frame 1. In this embodiment, the frame 1 is provided with a lifting drive mechanism 14 for driving the conveyor 2 to move up and down. The controller 10 is connected to the lifting drive mechanism 14 for lifting control. The lifting drive mechanism 14 adopts an electric telescopic rod or a cylinder for flexible extension and retraction. The controller 10 adopts a PLC to improve the level of automation of control.

[0016] In this embodiment, the frame 1 is vertically provided with slide rails 11 located on both sides of the conveyor 2, and the slide rails 11 are provided with sliders 15 connected to the side of the conveyor 2, which improves the lifting and lowering stability of the conveyor 2.

[0017] The conveyor 2 is a roller conveyor, which is connected to the controller 10 for operation control. The preceding process equipment delivers the plastic box 9 onto the conveyor 2, and the conveyor 2 moves the plastic box 9.

[0018] like Figure 1As shown, a crossbeam 12 is provided on one side of the frame 1, above the edge of the conveyor 2. Two displacement sensors 13 are arranged at intervals on the crossbeam 12. The displacement sensors 13 are connected to the controller 10 for signal transmission. When both displacement sensors 13 emit signals, it indicates that the plastic box 9 has moved into place on the conveyor 2, and the operation of the conveyor 2 is stopped.

[0019] The bearing seats 3 are positioned opposite each other on both sides of the top opening of the frame 1. A rotating shaft 4 is horizontally arranged within each bearing seat 3. The flip plate 5 is mounted on the rotating shaft 4 and points obliquely upwards towards the top of the conveyor 2. Figure 1 As shown, the flaps 5 on both sides of the rotating shaft 4 are arranged in an inverted V shape, which facilitates the rise of the plastic box 9 and opens the flaps 5.

[0020] like Figure 2 As shown, a limiting pin 6 is provided on one side of the flip plate 5. The limiting pin 6 flips with the flip plate 5 and limits the downward angle of the flip plate 5 when it contacts the bearing seat 3, so as to prevent the flip plate 5 from pointing obliquely downward to the conveyor 2 when it resets, thus ensuring safety.

[0021] Raised ribs 8 are provided on both sides of the top of the plastic box 9. Clamping pieces 7 corresponding to the raised ribs 8 are provided at the ends of the flip plate 5. The plastic box 9 is lifted by the rising of the conveyor 2, causing the raised ribs 8 of the plastic box 9 to contact the bottom surface of the flip plate 5, driving the flip plate 5 to flip upwards at an angle. When the height of the raised ribs 8 is higher than that of the clamping pieces 7, the clamping pieces 7 are located below the raised ribs 8 and clamp the plastic box 9. Figure 1 As shown, the rib 8 is used to limit the downward movement of the plastic box 9. At this time, the conveyor 2 descends and resets, and lifts the plastic boxes that are subsequently delivered upward in sequence to complete the stacking of the plastic boxes 9. The system has a high degree of automation, a simple structure, and low maintenance costs.

[0022] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
