Description

Technical Field

[0001] This invention relates to the field of loading and unloading technology, and in particular to an automatic loading and unloading device for containers. Background Technology

[0002] Currently, the traditional process for loading and unloading ceramic powder in bowls is done manually. After the ceramic powder is fired at high temperature, it is manually transported to a designated location for unloading. Only one bowl can be unloaded at a time. This process generates a large amount of dust, which has a significant impact on the health of workers. In addition, the bowls vary in size, and it is very inconvenient to unload larger bowls manually, resulting in waste and pollution of the powder. Loading bowls can also only be done manually by one person. The process involves a lot of dust and high temperatures, requiring a large amount of manpower. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic bowl loading and unloading device that can automatically load and unload bowls, handle large quantities of bowls, is highly efficient, saves manpower, and at the same time prevents dust and environmental pollution and avoids waste.

[0004] The automatic loading and unloading bowl equipment of the present invention is implemented as follows: it includes a bowl sorting device, a powder pouring device, a powder feeding device, and a bowl stacking and conveying device arranged in sequence. The bowl sorting device arranges several bowls into a neat row. The powder pouring device pours the bowls arranged in a row into a closed space with ventilation so as to pour the ceramic powder in the bowls into the powder collection bin. The powder feeding device uses a powder feeding mechanism with a dustproof structure to simultaneously feed the ceramic raw material powder into several bowls arranged in a row, and then sends them to the bowl stacking and conveying device for the next process.

[0005] By automatically emptying the ceramic powder from the rows of bowls arranged in a closed cavity, manpower is saved, the calcined bowls are prevented from injuring operators, and the expelled ceramic powder does not pollute the environment. The settled ceramic powder can also be recycled, avoiding waste.

[0006] Preferably, a bowl placement and positioning device and a bowl grasping device are provided in front of the bowl sorting device. The bowl placement and positioning device shapes and arranges several bowls from the conveying component into a predetermined shape, and the bowl grasping device transfers the shaped bowls to the bowl sorting device. In this way, the bowl placement and positioning device shapes several randomly distributed bowls into an orderly arrangement, facilitating subsequent operations, such as making it easier for the bowl grasping device to grasp them and place them in the bowl sorting device.

[0007] Preferably, a bowl cleaning device and a subsequent powder pouring device are sequentially arranged between the powder pouring device and the powder feeding device. After the ceramic powder is poured into the bowl by the powder pouring device, it is sent to the bowl cleaning device. The bowl cleaning device cleans the inner cavity of the bowl as it passes through, removing the ceramic powder adhering to the inner wall of the bowl. Then, it is sent to the subsequent powder pouring device, which pours the bowls arranged in a row into a ventilated enclosed space, so as to pour the ceramic powder swept out of the bowl into the powder collection bin.

[0008] Compared with existing technologies, this invention has the advantages of automatic loading and unloading of bowls, large loading and unloading capacity, high efficiency, saving manpower, preventing dust and environmental pollution, and avoiding waste. Attached Figure Description

Detailed Implementation

[0020] The automatic loading and unloading bowl device of the present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figure 1 As shown, the automatic loading and unloading bowl equipment of the present invention is implemented as follows: it includes a bowl sorting device b, a powder pouring device c, a powder dispensing device d, and a bowl stacking and conveying device e arranged sequentially. The bowl sorting device b arranges several bowls A into a neat row. The powder pouring device c pours the bowls A arranged in a row into a closed space with ventilation so that the ceramic powder in the bowls A can be poured into the powder collection bin. The powder dispensing device d uses a powder dispensing mechanism with a dustproof structure to simultaneously dispense the ceramic raw material powder into several bowls arranged in a row, and then sends them to the bowl stacking and conveying device e for the next process.

[0022] like Figure 1 , 2As shown, the bowl sorting device b includes a bowl sorting support 1, a bowl sorting power conveyor belt 2 mounted on the bowl sorting support 1, and two rows of parallel roller sets 3 mounted on the bowl sorting power conveyor belt 2. The front inlet end of the two rows of parallel roller sets 3 is trumpet-shaped, and the rear end of the two rows of parallel roller sets 3 is a straight guide groove. The spacing between the two rows of parallel roller sets 3 in the rear end matches the width of a single bowl A. During bowl sorting, several bowls A are placed at the front inlet end of the trumpet-shaped two rows of parallel roller sets 3, so that all bowls A are within the effective range of the projection of the front inlet end of the trumpet-shaped two rows of parallel roller sets 3. Under the action of the bowl sorting power conveyor belt 2, the bowls A enter the two rows of parallel roller sets 3 and, under the action of the trumpet-shaped front inlet end, are guided into the two rows of parallel roller sets 3 in the rear end in an arranged state, thus completing the effect of arranging several bowls A into a neat row.

[0023] like Figure 1 , 3 As shown, the powder pouring device c includes a powder pouring frame 4, a tilting mechanism 5 mounted on the powder pouring frame 4, a powder pouring conveying mechanism 6 tilted by the tilting mechanism 5, and a powder pouring power clamp 7 mounted on the powder pouring conveying mechanism 6. Below the powder pouring conveying mechanism 4 is a collection bin 8. The powder pouring frame 4 is a closed box with an exhaust vent 9. The powder pouring conveying mechanism of the box has a material inlet 10 and a material outlet 11. Below the powder pouring power clamp 7, directly opposite the center of the powder pouring power clamp, is an impact member 12 driven by a power device.

[0024] During operation, a certain number of bowls A containing ceramic powder are arranged in a row by the bowl sorting device b and then sent into the powder pouring and conveying mechanism 6. After reaching the set position, the powder pouring power clamp 7 is activated to clamp the bowls A. Then, the flipping mechanism 5 drives the powder pouring and conveying mechanism 6 to rotate 180 degrees, causing the bowls A to flip over with their openings facing down. The ceramic powder inside the bowls A is poured into the collection bin 8 below. At the same time, the power device drives the impactor 12 to impact the bottom surface of the bowls A. Through vibration, the ceramic powder remaining in the bowls A is shaken out and falls into the collection bin 8. During the pouring of ceramic powder, the exhaust device draws air from the sealed box through the exhaust port 9 to suck away and recycle the ceramic powder that has been dispersed into the air inside the sealed box.

[0025] like Figure 1 , 4As shown, the powder feeding device d includes a powder feeding support 13, a ceramic raw material silo 14 mounted on the powder feeding support 13, several material feeding ports 15 located at the lower part of the ceramic raw material silo 14, a powder feeding power transmission mechanism 16 located below the material feeding ports 15, a bowl posture shaping mechanism 17 located on both sides of the powder feeding power transmission mechanism 16, and a lifting mechanism 18 located below the powder feeding power transmission mechanism 16. The powder feeding support 13 is closed except for the material inlet and material outlet of the powder feeding power transmission mechanism 16. The cavity formed by the closed surface is connected to the exhaust equipment through the exhaust port.

[0026] During operation, a row of bowls A, fed from the powder pouring device c, enters the powder feeding power transmission mechanism 16. After being positioned front-to-back and left-to-right by the bowl posture shaping mechanism 17, the lifting mechanism 18 drives the powder feeding power transmission mechanism 16 to rise, so that each bowl A connects with the corresponding material feeding port 15. The material feeding port 15 feeds ceramic powder into the corresponding bowl A. The enclosed surface and the cavity formed by the enclosed surface are connected to the exhaust equipment through the exhaust port, so that the cavity forms a negative pressure, preventing dust raised during the feeding of ceramic powder from leaking out of the powder feeding device d and polluting the environment.

[0027] Preferably, such as Figure 1 , 5 As shown, the bowl stacking and conveying device e includes a bowl stacking support 19, a bowl stacking power transmission mechanism 20 mounted on the bowl stacking support 19, a bowl stacking guide mechanism 21 mounted on the front of the bowl stacking power transmission mechanism 20, and a bowl stacking power push plate 22 mounted on the bowl stacking support 19. During operation, bowls A fed from the powder feeding device d enter the bowl stacking power transmission mechanism 20 and, guided by the bowl stacking guide mechanism 21, are guided to the rear of the bowl stacking power transmission mechanism 20. Once the number of bowls A has been reached and stopped at the rear stop plate of the bowl stacking power transmission mechanism 20, the bowl stacking power push plate 22 actuates, pushing the rows of bowls A towards the side of the bowl stacking power transmission mechanism 20. After the set number of rows of bowls A have been pushed to the side of the bowl stacking power transmission mechanism 20, they are then conveyed away by the clamping mechanism.

[0028] Preferably, a bowl placement and positioning device f and a bowl grasping device g are provided before the bowl sorting device b. The bowl placement and positioning device f shapes and arranges several bowls A placed on the tray i by the bowl conveyor belt h into a predetermined shape. The bowl grasping device g conveys the shaped bowls A to the bowl sorting device b. In this way, the bowl placement and positioning device f shapes several randomly distributed bowls A into an orderly arranged bowl, which facilitates subsequent operations, such as making it easier for the bowl grasping device g to grasp them and place them in the bowl sorting device.

[0029] Preferably, such as Figure 1 , 6 As shown, the pot body placement and positioning device f includes a pot body placement and positioning bracket 23, a stop mechanism 24 located at the front end of the pot body placement and positioning bracket 23, a lifting mechanism 25 located in the middle of the pot body placement and positioning bracket 23, and front, back, left, and right clamping mechanisms 26 located around the lifting mechanism 25. A tray i loaded with pot bodies A is moved to the pot body placement and positioning device f by the pot body conveyor belt h. The stop mechanism 24 actuates, stopping the tray i loaded with pot bodies A in the middle of the pot body placement and positioning bracket 23. The lifting mechanism 25 actuates, lifting the tray i loaded with pot bodies A, so that the pot bodies A are within the range of action of the front, back, left, and right clamping mechanisms 26. The front, back, left, and right clamping mechanisms 26 actuate, arranging the several pot bodies A on the tray i into two neatly arranged pot body groups.

During operation, the lateral moving mechanism 28 moves the mechanical gripper 30 to the bowl placement and positioning device f, and the vertical moving mechanism 29 moves the mechanical gripper 30 to the bowl group. The mechanical gripper 30 then actuates to grip the bowl group. The vertical moving mechanism 29 then actuates, causing the mechanical gripper 30 to move upwards, lifting the bowl group from the tray i. The lateral moving mechanism 28 then moves the mechanical gripper 30 to the bowl sorting device b, placing the bowl group onto the bowl sorting power conveyor belt 2 at the front inlet end of the roller group 3 of the bowl sorting device b.

[0031] Preferably, a bowl cleaning device j and a subsequent powder pouring device c are sequentially arranged between the powder pouring device c and the powder feeding device d. After the ceramic powder is poured into the bowls by the powder pouring device, it is sent to the bowl cleaning device j. The bowl cleaning device j cleans the inner cavity of the bowls A as it passes through, removing the ceramic powder adhering to the inner wall of the bowls A. Then, it is sent to the subsequent powder pouring device c. The subsequent powder pouring device c pours the bowls A arranged in a row into a closed space with ventilation, so that the ceramic powder swept down from the bowls A can be poured into the powder collection bin 8.

A crossbar telescopic structure 40 is provided, and each crossbar hinge point of the crossbar telescopic structure 40 is respectively hinged to each slider 39. The power device 41 that drives the crossbar telescopic structure 40 to extend and retract drives the two adjacent sliders 39 to move relative to each other.

[0034] During operation, several bowls A arranged in a row from the powder pouring device c enter the bowl conveying device 38. After being positioned by the positioning structure 37, the up-down drive mechanism 33 drives the power sweeper 34 to move down into the bowl A. The power sweeper 35 then moves, and simultaneously, the forward-backward and left-right moving mechanism 32 moves, causing the power sweeper 35 to sweep along the inner wall of the bowl A, cleaning off the ceramic powder adhering to the inner wall of the bowl A. Then, the bowl A is sent to the powder pouring device c to empty the ceramic powder from the bowl A. The crossbar telescopic structure 40 is used to adjust the position of each power sweeper 35 to ensure that the power sweeper 35 accurately extends into the bowl A.

[0035] Preferably, a bowl positioning device k is provided before the bowl A enters the powder pouring device c. After the bowl A is positioned by the bowl positioning device k, the posture of each bowl A and the spacing between them meet the set requirements, so as to ensure that the set number of bowls A can be clamped by the powder pouring power clamp 7 when entering the powder pouring device c, and to ensure that when the set number of bowls A enters the powder feeding device d, they can be accurately positioned below each material feeding port 15.

Bowl A enters the bowl positioning device k under the drive of the bowl positioning conveying mechanism 43, first passing through the centering component 45 for centering to ensure that the posture and position of bowl A meet the set requirements. Then, under the obstruction of the bowl positioning braking mechanism 46, several bowls A are arranged one after another in a row. After the required number is reached, the power baffle 51 at the outlet end of the bowl positioning conveying mechanism 43 falls, and the bowl positioning braking mechanism 46 resets, allowing the row of bowls A with the required posture and position to enter the powder pouring device c. The two roller guide groups 44 form a guide groove so that the bowl A moves forward along the guide groove.

[0037] Preferably, a sorting and waiting device m is provided before the bowl A enters the powder feeding device d. The sorting and waiting device m allows a set number of bowls A in a row to wait in the sorting and waiting device m. Only after the previous batch of bowls A in the powder feeding device d leaves the powder feeding device d will the sorting and waiting device m allow the next row of bowls A to enter the powder feeding device d.
