[0024] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0025] refer to Figure 1 , Figure 2 and Figure 3 This application provides a door panel flipping device 100 for flipping the door panels of a container. The door panel flipping device 100 includes a base frame 110, a lifting frame 120, a flipping frame 140, and a reversing device 150.

[0026] The base frame 110 is mounted on the ground by several legs. Horizontal guide rails 111 are provided on both sides of the base frame 110 along the first horizontal direction D1. The horizontal guide rails 111 extend along the second horizontal direction D2, which is perpendicular to the first horizontal direction D1.

[0027] The lifting frame 120 spans both sides of the base frame 110 along the first horizontal direction D1. It has two vertical guide rails 124 arranged along the vertical direction D3, and the vertical guide rails 124 are connected to the middle of the horizontal guide rails 111. The connection between the vertical guide rails 124 and the horizontal guide rails 111 forms a transfer area. The lifting frame 120 is also provided with a lifting mechanism 130.

[0028] The flip frame 140 is disposed between two horizontal guide rails 111 of the base frame 110. The flip frame 140 has a receiving space 143, which opens along the second horizontal direction D2 and is used to receive a door panel. The flip frame 140 has a lifting part 145 disposed at the middle of both sides along the first horizontal direction D1. The lifting part 145 is connected to the lifting mechanism 130 and is configured to move along the vertical guide rail 124 under the action of the lifting mechanism 130. The flip frame 140 has a first end 141 and a second end 142 opposite along the second horizontal direction D2. The first end 141 has guide parts 144 disposed on both sides along the first horizontal direction D1. The guide parts 144 are configured to move along the horizontal guide rail 111. The second end 142 is configured to rotate about the lifting part 145 as a pivot.

[0029] The reversing device 150 is disposed on the base frame 110 and located in the transfer area. The reversing device 150 is used to apply a force to the guide 144 when the guide 144 moves to the transfer area so that the guide 144 can continue to move.

[0030] According to the door panel flipping device 100 of this application, the door panel flipping can be completed with a small footprint, and the flipping process can be completed in one station.

[0031] Preferably, the center of gravity of the flip frame 140 is offset towards the second end 142. It can be understood that the line connecting the two lifting parts 145 is offset relative to the center of gravity of the flip frame 140 along a second horizontal direction D2. As one implementation, the second end 142 of the flip frame 140 is provided with a weight-adding component 146, making the second end 142 heavier than the first end 141. Therefore, when the flip frame 140 rotates to a vertical position and the guide part 144 of its first end 141 continues to move forward a certain distance under the action of the reversing mechanism, the second end 142 of the flip frame 140 can fall down by itself under the action of gravity.

[0032] Specifically, the base frame 110 has two crossbeams on both sides along the first horizontal direction D1, and grooves are provided on the sides of the two crossbeams facing each other, forming horizontal guide rails 111. In other words, the horizontal guide rails 111 are constructed as grooves with openings facing each other. The guide portion 144 is constructed as a guide wheel, which is disposed in the groove.

[0033] The lifting frame 120 has two uprights 121 and a horizontal column 123. The two uprights 121 are spaced apart and connected to both ends of the base frame 110 along the second horizontal direction D2, preferably to the middle of the base frame 110 along the second horizontal direction D2. The horizontal column 123 connects between the tops of the two uprights 121. A vertical guide rail is provided on the uprights 121. The lifting frame 120 is also provided with a moving part 134, which is provided on the vertical guide rail 124 and configured to move along the vertical guide rail 124. The moving part 134 is connected to the lifting mechanism 130 and is rotatably connected to the lifting part 145 of the flipping frame 140. Preferably, the moving part 134 and the lifting part 145 are connected by a bearing, thereby enabling large-angle rotation between them. The column 121 includes two spaced vertical beams 122, which form a vertical guide rail 124. A movable part 134 is disposed between the two vertical beams 122, and a guide bearing 135 is provided on the movable part 134. The movable part 134 is connected to the vertical beams 122 through the guide bearing 135.

[0034] As an optional implementation, the lifting mechanism 130 includes a power unit and a chain 133. The power unit is located on the side of the column 121, and a sprocket device 136 is provided on the top of the column 121. One end of the chain 133 is connected to the moving part 134, and the other end passes around the sprocket device 136 and is connected to the power unit. Under the action of the power unit, the moving part 134 can be driven to rise and fall along the vertical guide rail 124 via the chain 133.

[0035] The power unit includes a power cylinder 131, which is mounted on one of the two columns 121. The telescopic end of the power cylinder 131 faces upward and is connected to one end of the chain 133, thereby enabling the moving part 134 to rise through contraction. The power unit also includes a counterweight 132, which is located to the side of the other of the two columns 121 and is suspended from the chain 133. Thus, the counterweight 132 provides balance on the other side, making the raising and lowering of the moving part 134 more stable.

[0036] The reversing device 150 includes a swing arm 151 and a reversing cylinder 152. The swing arm 151 is pivotally connected to the base frame 110, and the reversing cylinder 152 is disposed on the base frame 110, with its extension and retraction end connected to the swing arm 151. Optionally, the reversing device 150 is disposed on both sides of the base frame 110 along the first horizontal direction D1.

[0037] As a preferred embodiment, continue to refer to Figure 1 and Figure 2 The door panel flipping device 100 also includes a conveying mechanism 160, which is located below the base frame 110. The conveying mechanism 160 includes a roller assembly 161 and a lifting device 162. The roller assembly 161 extends along a second horizontal direction D2, and the lifting device 162 is located at the bottom of the roller assembly 161. The lifting device 162 is used to raise the roller assembly 161 to the position of supporting the door panel when the door panel enters the flipping frame 140.

[0038] In an embodiment not shown, the conveying mechanism 160 may further include a conveying driver connected to the roller device 161, which drives the roller device 161 to move the door panel along the second horizontal direction D2.

[0039] As an example, when a door panel needs to be flipped, an operator can move the door panel to the door panel flipping device 100 on the production line and place it into the receiving space 143 of the flipping frame 140. Simultaneously, the conveyor mechanism 160 is controlled to lift the door panel, ensuring it is fully incorporated into the flipping frame 140. After the door panel is in place, the control cylinder 131 pulls the chain 133, causing the moving part 134 on the vertical guide rail 124 to move upwards. The moving part 134, together with the lifting part 145 of the flipping frame 140, tends to move upwards. However, because the guide part 144 of the first end 141 of the flipping frame 140 is restricted from moving upwards by the horizontal guide rail 111, while the second end 142 can move freely upwards, the second end 142 rotates upwards relative to the lifting part 145 of the flipping frame 140, while the first end 141 moves towards the center under the influence of the movement. When the flip frame 140 moves to the vertical position (at which point the second end 142 rotates 180°), the control reversing cylinder 152 drives the swing arm 151 to pivot, continuing to move towards the lifting section 145 in the intermediate transfer area, causing the second end 142 to rotate more than 180°. Thus, the heavier second end 142 has completed its turn and can fall under gravity, allowing the entire flip frame 140 to flip. After the flip is complete, the operator removes the door panel from the flip frame 140.

[0040] In summary, the door panel flipping device 100 of this application has a flipping radius of the door panel that is much smaller than the length of the door panel, which can achieve near-in-situ flipping of the door panel, greatly reducing the space occupied by the flipping station, and making the door panel at the same height before and after flipping, thus improving production efficiency.

[0041] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.
