Description

Technical Field

[0001] This utility model relates to a cleaning production line, and more particularly to a high-altitude depalletizing and palletizing cleaning system for cleaning plastic frames such as chicken cages and vegetable baskets. Background Technology

[0002] Plastic crates are often made by thermoplastic extrusion molding because they are large in size and low in cost, and are generally used to transport vegetables, poultry, fruits, canned food and other foods. To facilitate storage or transportation, most manufacturers currently use stacking to palletize plastic crates, and then store or transport the palletized crates as a whole.

[0003] Plastic crates are typically cleaned after transporting goods for reuse. However, because the crates are stacked during transport, to ensure proper cleaning and that each crate receives adequate cleaning, they must first be unstacked and cleaned individually before being stacked again. This process is quite cumbersome. Furthermore, existing cleaning equipment cannot perform unstacking and stacking, necessitating either specialized equipment or manual labor, increasing costs and reducing efficiency.

[0004] In addition, due to the relatively long plastic frame cleaning production line, some high-altitude cleaning lines are set up to save factory space. For these high-altitude cleaning lines, the plastic frames to be cleaned need to be transported onto the line, cleaned, and then transported back to the ground for stacking. Existing high-altitude cleaning lines involve moving all the plastic frames to a single lifting point and then lifting them to a high altitude using a lifting mechanism. Since the frames to be cleaned, such as chicken coops, are often scattered and heavy, moving them all to one location for lifting is cumbersome and wastes manpower. Furthermore, the stacking process after cleaning is also troublesome. If stacked manually, the plastic frames need to be repeatedly lifted and stacked. The higher the stack, the higher the workers need to lift the frames, which is more physically demanding. If the stack is too high, ladders or other lifting tools are needed. Workers also face safety hazards when moving heavy objects at heights. Especially after cleaning, the frames are wet and slippery, making manual stacking even more difficult. Summary of the Invention

The cleaning system is equipped with multiple lifting ports to facilitate the lifting process of the frames to be cleaned, and the outlet is equipped with a bidirectional stacking device, which can be used to automatically stack the cleaned plastic frames, improve stacking efficiency, and reduce labor costs.

[0016] The beneficial effects of this utility model are:

[0038] An embodiment provides a high-altitude depalletizing, palletizing, and cleaning system, such as Figures 1 to 3 As shown, the system includes a linearly arranged aerial conveyor frame 1, which is supported by multiple support frames. Multiple feeding lifting frames 2 are equidistantly distributed on one side of the aerial conveyor frame 1, primarily used to lift plastic frames to be cleaned. Due to the large size of the overall structure shown in the attached drawing, [further details are needed]. Figures 1 to 3This is just a schematic diagram; the multiple feeding and lifting frames 2 in the middle are omitted. A bidirectional stacking device 3 is located at the end of the aerial conveyor frame 1. The discharge end of the aerial conveyor frame 1 connects to the feed end of the bidirectional stacking device 3. An aerial cleaning device 4 is installed in the area between the last aerial conveyor frame 1 and the bidirectional stacking device 3. This cleaning system simultaneously lifts the plastic frames to be cleaned onto the aerial conveyor frame 1 via multiple feeding and lifting frames 2, and then transports them to the aerial cleaning device 4 via a conveying mechanism on the aerial conveyor frame 1 for cleaning. After cleaning, the frames are then transported back to the bidirectional stacking device 3 via the aerial conveyor frame 1 for stacking. The conveying mechanism of the aerial conveyor frame 1 runs through the entire production line, realizing a continuous cleaning process. The conveying mechanism on the aerial conveyor frame 1 can be a belt conveyor or a chain conveyor, controlled by a drive motor. The area of ​​the aerial conveyor frame 1 with the feeding lifting frame 2 can be welded to the frame of the feeding lifting frame 2, and the feeding lifting frame 2 can also be used as a support frame. In the area without the feeding lifting frame 2, that is, the area where the aerial cleaning device 4 is installed, multiple support frames are provided for support. All frame structures are made of square steel welded to ensure that their load-bearing capacity can meet the normal transportation and cleaning process.

[0039] An embodiment provides a high-altitude depalletizing, palletizing, and cleaning system, such as Figure 4 and Figure 5As shown, the feeding lifting frame 2 is equidistantly arranged. The feeding lifting frame 2 includes a portal frame 200 and a chain lifting mechanism 201 mounted on the portal frame 200. The height of the portal frame 200 is greater than the height of the aerial conveyor frame 1, ensuring that the plastic frame to be cleaned is lifted to a position higher than the aerial conveyor frame 1 and pushed onto the aerial conveyor frame 1 for transport. The chain lifting mechanism 201 includes two sets of symmetrically arranged lifting chains. Each set of lifting chains includes two upper and lower rotating shafts and two chains. Two chain drive wheels are fixed on the upper and lower rotating shafts respectively. The upper and lower ends of each chain are respectively sleeved on two corresponding chain drive wheels. Each set of lifting chains is equipped with a drive motor, which controls the rotating shafts to drive the chain drive wheels to rotate, thereby controlling the up and down movement of the chain. Lifting plates 202 are symmetrically arranged on the two sets of lifting chains. The chain lifting mechanism 201 can be the anti-tilting chain lifting device disclosed in the utility model patent CN211366809 U filed by the inventor in 2019. It is installed inside the portal support frame 200 and lifts the plastic frame to be cleaned via two L-shaped lifting plates 202. A pushing mechanism 203 is provided at the same height as the aerial conveyor frame 1. The pushing mechanism can be a hydraulic cylinder, pneumatic cylinder, or electric cylinder, with a push plate at its piston end. The pushing mechanism 203 is perpendicular to the aerial conveyor frame 1, with its push plate facing the aerial conveyor frame 1, and can horizontally push the frame to be cleaned, which has been lifted to the same height as the aerial conveyor frame 1, onto the aerial conveyor frame 1 for transport.

[0040] An embodiment provides a high-altitude depalletizing, palletizing, and cleaning system, such as Figures 1 to 3 As shown, the high-altitude cleaning device 4 includes a protective shell covering the high-altitude conveyor frame 1. The protective shell forms a cleaning and disinfection chamber with open ends on the high-altitude conveyor frame 1. The cleaning and disinfection chamber includes a cleaning chamber, a disinfection chamber, and a drying chamber sequentially from the inlet end to the outlet end. Multiple high-pressure water spray heads are arranged on both sides and the top of the cleaning chamber, and these high-pressure water spray heads are connected to an external water supply system through high-pressure water pipes. Disinfection spray heads are arranged on both sides and the top of the disinfection chamber, and these disinfection spray heads are connected to an external disinfection liquid delivery system through pipes. A high-pressure pipe is arranged in the drying chamber, and this high-pressure air pipe is connected to an external high-pressure blower. The high-altitude cleaning device 4 can use an existing cleaning device, which is installed on the high-altitude conveyor frame 1. During the conveying process of the high-altitude conveyor frame 1, the plastic frames to be cleaned will pass through the cleaning and disinfection chamber of the high-altitude cleaning device 4 for cleaning, disinfection, and drying. The water used for cleaning can be directly discharged into an underground wastewater pool.

[0041] An embodiment provides a high-altitude depalletizing, palletizing, and cleaning system, such as Figures 6 to 13As shown, the bidirectional stacking device 3 includes a bidirectional pushing mechanism 300, a conveying mechanism 301, a chain lifting mechanism 303, and two sets of portal-shaped stacking frames 302 symmetrically arranged on both sides of the bidirectional pushing mechanism. The portal-shaped stacking frames 302 are frame structures welded from square steel, serving as the main support frame. The hollow area of ​​the portal-shaped stacking frames 302 forms a stacking space, which can be used for stacking plastic frames or boxes. To ensure the device's integrated design, the two sets of portal-shaped stacking frames 302 can be welded together using square steel. The conveying mechanism 301... The conveying mechanism 301 is a conventional conveyor, which can be a chain conveyor or a belt conveyor. The frame of the conveying mechanism 301 is also welded from square metal steel and can be welded together with the two sets of gantry stacking racks 302. The conveying mechanism is controlled by a motor. The conveying mechanism 301 is located at the bottom of the hollow area of ​​the two sets of gantry stacking racks 302. The conveying direction of the conveying mechanism 301 is consistent with the pushing direction of the bidirectional pushing mechanism 300. The conveying mechanism 301 is used to transport the stacked whole frame or box to the next process.

[0042] An embodiment provides a high-altitude depalletizing, palletizing, and cleaning system, such as Figures 6 to 13 As shown, the bidirectional pushing mechanism 300 is mounted on top of two sets of portal stacking racks 302. Below the bidirectional pushing mechanism 300 is a pushing platform 304, which is positioned between the two sets of portal stacking racks 302, with both ends connected to the hollow areas of the two sets of portal stacking racks 302. The function of the bidirectional pushing mechanism 300 is to push the frames or boxes on the pushing platform 304 into the hollow stacking areas of the two portal stacking racks 302. Two sets of chain lifting mechanisms 303 are provided, each set equipped with a carrying rack 305. The two sets of chain lifting mechanisms 303 are respectively mounted on the two sets of portal stacking racks 302, with their carrying racks 305 extending horizontally into the hollow areas of the corresponding portal stacking racks 302. The highest point of each set of chain lifting mechanisms 303 matches the height of the pushing platform 304, and the lowest point matches the height of the conveying mechanism 301. The pushing platform 304 is a support platform composed of multiple parallel rollers, and the rotation direction of the rollers of the pushing platform 304 is perpendicular to the pushing direction of the bidirectional pushing mechanism 300. The pushing platform 304 can dock with the external frame or box conveying mechanism to receive the frame or box conveyed from the outside, and then push it into the two-sided portal stacking racks 302 through the bidirectional pushing mechanism 300. The frame entering the portal stacking rack 302 is supported by the load rack 305 on the chain lifting mechanism 303, and during the stacking process, it is driven down by the chain lifting mechanism 303 to a position at the same height as the conveying mechanism 301, and then conveyed away by the conveying mechanism 301.

[0043] like Figures 11 to 13As shown, the bidirectional pushing mechanism 300 in this embodiment includes a pushing frame 3001 and a pushing cylinder or pneumatic cylinder 3002. The pushing frame 3001 is fixedly connected between the tops of two sets of portal stacking racks 302. The pushing cylinder or pneumatic cylinder 3002 is installed on one side of the pushing frame 3001, and the pushing direction of the pushing cylinder or pneumatic cylinder 3002 is consistent with the conveying direction of the conveying mechanism 301. The piston rod 3007 of the pushing cylinder or pneumatic cylinder 3002 extends horizontally into the pushing frame 3001. A pushing plate 3003 is provided at the end of the piston rod 3007. The pushing plate 3003 extends vertically above the pushing platform 304. Two sliding rods 3004 are correspondingly provided on the pushing frame 3001. The two sliding rods 3004 are arranged parallel and symmetrically on both sides of the piston movement path of the pushing cylinder or pneumatic cylinder 3002. There are two pushing plates 3003. The two pushing plates 3003 are slidably connected to the sliding rods 3004 through sliders 3005 respectively. The travel distance of the pushing cylinder or pneumatic cylinder 3002 is matched with the distance between the two sets of portal stacking racks 302. A limiting hole 3006 matching the end of the piston rod 3007 is provided at the mounting end of the pushing rack 3001 away from the pushing cylinder or pneumatic cylinder 3002. During the extension and retraction of the piston rod 3007 of the pushing cylinder or pneumatic cylinder 3002, the pushing plate 3003 will slide left and right along the slide rod 3004. When sliding to the left, it pushes the frame or box on the pushing platform 304 onto the load rack 305 in the hollow area of ​​the left portal stacking rack 302; when sliding to the right, it pushes the frame or box on the pushing platform 304 onto the load rack 305 in the hollow area of ​​the right portal stacking rack 302. The bidirectional pushing mechanism 300 can achieve uninterrupted left and right pushing, thus realizing an uninterrupted left and right stacking process.

[0044] The chain lifting mechanism 303 in the embodiment, such as Figures 6 to 9 As shown, the system includes two sets of lifting chains symmetrically arranged on a portal stacking rack 302. Each set of lifting chains includes a motor 3031, an upper rotating rod 3032, a lower rotating rod 3033, and two chains 3034. The upper rotating rod 3032 is rotatably mounted at a position equal to or higher than the pushing platform 304, and the lower rotating rod 3033 is rotatably mounted at a position equal to or lower than the conveying mechanism 301. The motor 3031 is mounted at the end of one of the rotating rods and fixed to the portal stacking rack 302. Each set of lifting chains is equipped with a carrying rack 305, and the carrying racks 305 on the two sets of lifting chains are symmetrically arranged on the chains 3034. The carrying rack 305 is an L-shaped support plate. Each set of lifting chains has two carrying racks 305, and the distance between the two carrying racks 305 matches the stacking height of the hollow area of ​​the portal stacking rack 302. The vertical plate of each L-shaped support rack is fixed to the two chains 3034 of one set of lifting chains.

[0045] Two sets of lifting chains on each gate-type stacking rack 302 can be used to support the frames or boxes entering the gate-type stacking rack 302. The motor 3031 is a stepper motor, and its single control of the chain 3034 to move a height matched with the height of a single frame or box to be stacked. When a plastic frame enters on each side, the motor 3031 drives the chain 3034 and the carrying rack 305 to descend by the height of one plastic frame, ensuring that there is sufficient height for stacking when the next plastic frame enters the gate-type stacking rack 302. Two sets of carrying racks 305 are provided on the two chains 3034 on each side, mainly to enable continuous stacking after a set of plastic frames has been stacked, without interruption.

[0046] To ensure that each plastic frame can stably fall onto the shelf 305 when pushed into the door-type stacking rack 302, such as Figures 6 to 10 As shown, a buffer frame 306 is also provided on the upper part of each group of portal stacking racks 302. The buffer frame 306 is set at the same height as the push platform 304 on the upper part of the hollow area of ​​the portal stacking rack 302. The buffer frame 306 on each group of portal stacking racks 302 includes two sets of buffer supports. Each set of buffer supports includes a control cylinder 3061, a hinge rod 3062 and a buffer plate 3063. The control cylinder 3061 is vertically fixed on the portal stacking rack 302. One end of the hinge rod 3061 is rotatably connected to the piston end of the control cylinder 3061, and the other end is rotatably connected to the buffer plate 3063. The connecting shaft between the hinge rod 3061 and the buffer plate 3063 is fixed on the portal stacking rack 302 through a support frame. The buffer plate 3063 extends horizontally to the hollow area of ​​the portal stacking rack 302 and matches the height of the push platform 304. The frames or boxes that enter the gate-type stacking rack 302 first fall onto the buffer plate 3063. Then, under the action of the control cylinder 3061, the buffer plate 3063 is flipped downwards, so that the frames or boxes fall onto the carrying rack 305 directly below the buffer plate 3063, thus achieving the purpose of buffering.

[0047] In operation, this invention involves multiple feeding lifting frames 2 simultaneously lifting the plastic frame to be cleaned onto the high-altitude conveyor frame 1. The frame is then transported to the high-altitude cleaning device 4 via a conveying mechanism on the high-altitude conveyor frame 1 for cleaning. After cleaning, the frame is transported again via the high-altitude conveyor frame 1 to the bidirectional stacking device 3. The cleaned plastic frame is then transported to the pushing platform 304, and then pushed into the hollow area of ​​the two-sided portal stacking racks 302 by the bidirectional pushing mechanism 300. The bidirectional pushing mechanism 300 moves left and right, pushing the frame into different sides of the portal stacking racks 302 each time. The frames or boxes of the stacking rack 302 first fall onto the buffer plate 3063. After being buffered by the buffer plate 3063, they fall onto the carrying rack 305. When a plastic frame falls onto the carrying rack 305, the motor 3031 is controlled to drive the chain 3034 to step downward once, causing the carrying rack 305 and the frames or boxes to move downward a certain height. When the carrying rack 305 moves to the bottom of the gate-type stacking rack 302, a stack of cleaned plastic frames has been stacked on the carrying rack 305. Then, with manual assistance, the entire stack of frames or boxes on the carrying rack can be moved onto the conveying mechanism 301 and transported to the next process.

[0048] The entire process of this invention can be controlled by only one worker, or the entire device can be set to automatic control. By setting sensors on various components, the device can automatically control the next step when the sensor is in position.

[0049] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
