Description

Technical Field

[0001] The invention relates to the technical field of shell sorting, in particular to a thin-wall shell overturning and sorting device for a refrigerator. Background Art

[0002] In the production and manufacturing process of refrigerators, thin-walled shells are key components, and their processing and assembly processes have strict requirements on the order and posture of the shells. Automatic sorting of thin-walled shells mainly refers to arranging scattered and disordered shells through a device to obtain a series of shells with consistent shell opening directions, which is convenient for use in subsequent workstations.

[0003] Traditional thin-walled shell sorting devices for refrigerators often need to rely on complex power systems to drive the shell movement and sorting. Common ones include motor-driven conveyor belts or hydraulic drive devices to move the shells on the track and complete the sorting. However, the operation of the equipment requires continuous consumption of a large amount of electricity or hydraulic oil, which makes the energy cost high. The purchase, installation and maintenance costs of the overall equipment are also greatly increased due to the complexity of the power system. In terms of sorting effect, when simply relying on conveyor belt sorting, once the number of shells is large, the shells often collide and pile up due to uneven speed. This may not only cause scratches on the appearance of the shell and damage to the structure, but also seriously affect the subsequent transportation, processing, assembly and other links, greatly restricting the improvement of production efficiency. At the same time, most of the existing sorting equipment has a single function and can only complete the shell sorting. It is impossible to effectively adjust the shell posture. In order to meet the specific requirements of the subsequent production process for the shell posture, the company has to add a special posture adjustment process and purchase corresponding supporting equipment. This undoubtedly further increases the production cost, prolongs the production cycle, and reduces the production efficiency of the product. Summary of the invention

[0013] As a further improvement of the present technical solution, a barb is provided at the lower end of the movable rod, and the barb is provided at the center position of the feeding barrel. When the closed end of the shell contacts the barb, the closed end of the shell pushes the barb to rotate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

The rocker arm is driven by the gravity of the shell to rotate and smoothly enter the feed barrel. No additional power equipment is required during the whole process, which greatly saves energy consumption. At the same time, when the rocker arm rotates, a series of components such as the cylindrical rod, the pull rope, and the limit plate are linked, so that the control rod can control the movement of the shells in different positions in turn, ensuring that each shell maintains a suitable interval and orderly arrangement, providing a good material preparation basis for subsequent production processes such as transportation, processing, and assembly, and greatly improving the smoothness and reliability of the overall production process.

[0015] 2. In the thin-walled shell flipping and sorting device for the refrigerator, when the shell enters the cylindrical barrel, no matter the shell initially enters with the closed end facing downward or the open end facing downward, through the coordinated effect of structures such as the barb, movable rod and spring damper and gravity, the shell posture can be accurately adjusted to the closed end always facing downward and the open end always facing upward, reducing the additional adjustment and positioning operations caused by the confusion of the shell direction in the production process, helping the continuous production line to receive the shell in the same posture, and significantly improving the overall production rhythm and efficiency.

Under its own gravity, the shell pushes the control device 2 to contact and rotate, and the control device 2 rotates without blocking the shell, so that the shell continues to move downward into the cylindrical barrel 1101. No additional power equipment is required to drive the whole process, which greatly saves energy consumption; the rotation of the control device 2 drives the unloading device 3 to rotate, and the rotation of the unloading device 3 controls the downward movement speed of the shell, so that the shell is intermittently sorted, ensuring that each shell maintains a suitable interval and orderly arrangement, providing a good material preparation basis for subsequent production processes such as transportation, processing, and assembly, and greatly improving the smoothness and reliability of the overall production process; when the shell moves into the cylindrical barrel 1101, the shell pushes the flipping device 4 to rotate, and the rotation of the flipping device 4 drives the shell to flip, so that the open end of the shell is always facing upward, and the shell with the open end facing upward falls from the cylindrical barrel 1101 to the conveying component 1 and is transported away.

[0021] See also Figure 3-Figure 6 As shown, the control device 2 includes a side plate 21 fixedly connected to one side of the support plate 1201, the upper side of the side plate 21 is rotatably connected to a fixing rod 22, the upper end of the fixing rod 22 is fixedly connected to a swing rod 23, and the end of the swing rod 23 away from the fixing rod 22 penetrates the side wall of the arc-shaped placement plate 1202. Figure 1-Figure 2 As shown, two notches 1203 are provided on one side of the arc-shaped placement plate 1202, and the control rod 35 and the swing rod 23 are respectively arranged at the positions of the two notches 1203; First, multiple shells are placed arbitrarily on the arc-shaped placement plate 1202, and the shells are placed on one side of the control rod 35, between two control rods 35, and between the control rod 35 and the rocker arm 23 in turn. The control rod 35 blocks the shell on the arc-shaped placement plate 1202, and the shell between the control rod 35 and the rocker arm 23 moves downward along the inclined surface of the arc-shaped placement plate 1202. In the initial state, the rocker arm 23 blocks the shell. When the shell moves downward, it contacts the rocker arm 23, and pushes the rocker arm 23 to rotate downward under the gravity of the shell itself. The rotating rocker arm 23 no longer blocks the shell, so that the shell continues to move downward into the feeding barrel 1102 and enters the cylindrical barrel 1101. The rocker arm 23 is pushed to rotate by the shell's own gravity, and no additional power device is required to push the shell to move, which saves energy and equipment costs, makes the feeding process more natural and smooth, and improves work efficiency.

[0022] See also Figure 6 As shown, the lower end of the swing rod 23 is fixedly connected to the cylindrical rod 24, and the lower end of the cylindrical rod 24 is fixedly connected to the pull rope 25. The other end of the pull rope 25 is fixedly connected to the limit plate 32 and the side away from the clamping block 33. When the swing rod 23 rotates downward, it drives the cylindrical rod 24 to rotate, and the rotation of the cylindrical rod 24 pulls the pull rope 25 to rotate.

[0023] See also Figure 3-Figure 7 As shown, the unloading device 3 includes a second side plate 31 fixedly connected to one side of the support plate 1201, a rotating rod 34 is fixedly connected to the upper side of the second side plate 31, a cylindrical block is fixedly connected to the upper end of the rotating rod 34, a plurality of control rods 35 are arranged in an outer circumferential array of the cylindrical block, the upper side of the second side plate 31 is rotatably connected to a limiting plate 32, the other end of the limiting plate 32 is fixedly connected to a clamping block 33, the lower end of the rotating rod 34 is fixedly connected to a fixing plate 36, and the fixing plate 36 is arranged below the rotating rod 34, a plurality of clamping grooves 37 adapted to the clamping block 33 are opened on the outside of the fixing plate 36, a rectangular block 38 is arranged between the cylindrical block and the fixing plate 36, and the rectangular block 38 is sleeved on the rotating rod 34, one side of the rectangular block 38 is fixedly connected to the support plate 1201, and one side of the rectangular block 38 is fixedly connected to the upper side of the limiting plate 32 by a tension spring 39; The pull rope 25 drives the limit plate 32 to rotate and stretch the tension spring 39. The rotation of the limit plate 32 drives the clamping block 33 to rotate. The clamping block 33 rotates without contacting the clamping groove 37 and disengages from the clamping groove 37, so that the clamping block 33 does not limit the position of the fixing plate 36. At this time, the shell between the two control rods 35 pushes the control rod 35 to rotate under its own gravity. The rotation of the control rod 35 causes the shell between the two control rods 35 to move downward toward the swing rod 23, and the shell on one side of the control rod 35 moves between the two control rods 35. When the control rod 35 rotates, it drives the fixing plate 36 to rotate through the rotating rod 34. When the swing rod 23 below is out of contact with the shell, The reaction force of the tension spring 39 drives the limit plate 32 to rotate and reset. The limit plate 32 rotates and drives the rocker arm 23 to reset through the pull rope 25. The rocker arm 23 resets to prepare for the next shell to be unloaded. The limit plate 32 is driven to move into the clamping groove 37 while resetting, so that the clamping block 33 clamps the clamping groove 37 and limits the fixed plate 36. The shell downward movement speed is controlled by the control rod 35, so that the shells are intermittently sorted, which can ensure that a certain interval and sequence are maintained between each shell, avoid mutual collision, accumulation or confusion between the shells, and facilitate the realization of automated control of the entire production process, reduce manual intervention, and improve production efficiency and production consistency.

[0024] See also Figure 8-Figure 10 As shown, the flip device 4 includes a connecting rod 41 fixedly connected to the inner wall of the cylindrical barrel 1101, a movable rod 42 is rotatably connected to the connecting rod 41, a spring damper 43 is fixedly connected to the side wall of the connecting rod 41 and one side of the movable rod 42, a barb 44 is provided at the lower end of the movable rod 42, and the barb 44 is provided at the center position of the feed barrel 1102, when the closed end of the shell contacts the barb 44, the closed end of the shell pushes the barb 44 to rotate, and when the open end of the shell contacts the barb 44, the barb 44 extends into the open end of the shell and pushes the barb 44 to rotate; When the shell moves to the inside of the cylindrical barrel 1101 through the feed barrel 1102, since the shell is placed randomly, there are two situations when the shell is unloading. The first situation is that the closed end of the shell faces downward. Since the closed end of the shell is a solid end, when the shell continues to fall under the action of gravity, the closed end will directly apply a downward thrust to the barb 44, causing the barb 44 to rotate around its rotation fulcrum. The barb 44 is connected to the movable rod 42, and the rotation of the barb 44 will drive the movable rod 42 to rotate. At the same time, the movable rod 42 is connected to the spring damper 43. During the rotation of the movable rod 42, the spring damper 43 will be stretched. When the spring damper 43 is stretched, on the one hand, elastic potential energy is stored, and on the other hand, Its damping characteristics will have a certain buffering and hindering effect on the rotation of the movable rod 42, so that the entire rotation process will not be too violent. Since the shell is tilted inside the feed barrel 1102, the center of gravity of the shell is not on the vertical center line. When the closed end pushes the hook 44 to rotate, the shell continues to fall. The gravity acts on the tilted shell to generate a torque that causes it to rotate. At the same time, the closed end and the hook 44 have interacted with each other. The position state of the hook 44 and the movable rod 42 has a certain constraint on the movement of the shell. Under the joint action of gravity, rotational inertia and constraint conditions, the shell will gradually adjust its posture during the falling process, so that the closed end of the shell always remains downward and the open end faces upward. The second situation is that the opening end of the shell is facing downward. When the opening end of the shell enters the cylindrical barrel 1101 downward, the barb 44 will extend from the opening end into the interior of the shell. Since the interior of the opening end is empty, the barb 44 can directly enter the interior of the shell. As the shell continues to fall, the movable rod 42 contacts the edge of the opening of the shell. The shell continues to fall under the action of gravity. The edge of the opening of the shell will apply an upward thrust to the movable rod 42, causing the movable rod 42 to rotate upward around its connection point. Similarly, the rotation of the movable rod 42 will stretch the spring damper 43, causing it to store elastic potential energy and produce a damping effect. In addition, since the closed end of the shell is a solid structure, its mass is larger than that of the open end, that is, the center of gravity is closer to the closed end. When the shell falls, under the action of gravity, the closed end with larger mass will tend to move downward more easily. At the same time, the interaction between the spring damper 43 and the movable rod 42 will give the shell a torque to adjust its posture, causing the shell to flip over, so that the closed end of the shell is always facing downward and the open end is facing upward when falling, ensuring that each shell maintains a consistent direction during the falling process, improving the accuracy of the entire sorting process, and facilitating subsequent processing steps.

[0025] When the thin-wall shell flipping and sorting device of the refrigerator of the present invention is used, the shell is first placed on the arc-shaped placement plate 1202 at random, and the control rod 35 blocks the shell. The shell located between the control rod 35 and the swing rod 23 moves downward with the inclined surface of the arc-shaped placement plate 1202. The shell pushes the swing rod 23 to rotate downward by its own gravity and then enters the feed barrel 1102. This process does not require additional power and is natural and smooth. The rotation of the swing rod 23 drives the cylindrical rod 24, and then pulls the pull rope 25, so that the limit plate 32 rotates and stretches the tension spring 39, and the clamping block 33 is separated from the clamping groove 3 7. The shell located between the two control rods 35 pushes the control rod 35 to rotate and move downward, and the shell located on one side of the control rod 35 moves between the two control rods 35. The rotation of the control rod 35 drives the fixed plate 36 to rotate. After the swing rod 23 is out of contact with the shell, the tension spring 39 drives the limit plate 32 to reset, thereby resetting the swing rod 23. At the same time, the clamping block 33 re-clamps the clamping groove 37 to limit the fixed plate 36, ensuring that a certain interval and order are maintained between each shell, avoiding mutual collision, accumulation or confusion between the shells, which is conducive to the smooth progress of the subsequent production process; There are two situations when the shell enters the cylindrical barrel 1101. If the closed end of the shell faces downward, the closed end pushes the barb 44 to rotate, drives the movable rod 42 and stretches the spring damper 43. Because the shell is tilted in the feed barrel 1102, gravity generates a torque that promotes rotation. Combined with the constraints of the barb 44 and the movable rod 42 on its movement, the closed end of the shell always faces downward when it falls, and the open end faces upward. If the open end of the shell faces downward, the barb 44 enters from the open end, and the movable rod 42 is pushed upward by the edge of the opening to rotate, stretching the spring damper 43. Because the closed end has a large mass and the center of gravity is close to the closed end, the torque generated by the interaction of gravity and the spring damper 43 and the movable rod 42 prompts the shell to flip. When it finally falls, the closed end always faces downward and the open end faces upward, ensuring that each shell maintains a consistent direction during the falling process, which can make the production process smoother and reduce the additional operations such as adjustment and positioning required due to the confusion of the shell direction. On a continuous production line, each shell can enter the subsequent equipment in the same posture, which helps to improve the overall production rhythm and thus improve production efficiency.
