Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a feeding and stacking device and method. Background Technology

[0002] In the packaging, logistics and printing industries, folding color boxes (such as cigarette packs, medicine boxes, cosmetic boxes, food boxes, etc.) are usually stored and transported in the form of tightly stacked "stacks" after printing, die-cutting and other processes are completed, and then delivered to the downstream packaging production line.

[0003] As a key link in the entire automation process, the starting station of the production line is responsible for placing the stacks of materials that are tightly packed together at the designated station. Then, the staff will sort and supply them. However, the process is inefficient and has poor quality stability. It is impossible to achieve automatic and continuous supply of stacks and to carry out efficient and stable sorting operations for each stack. This has become a key bottleneck restricting the automation upgrade and intelligent development of the entire production line.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a material feeding and stacking device and method to achieve automatic and continuous supply of material stacks, and to perform efficient and stable separation operations on each stack, thereby reducing reliance on manual operation and improving the efficiency and stability of stacking operations.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The feeding and stacking device includes:

[0008] frame;

[0009] A horizontal conveying mechanism is disposed on the frame and configured to carry and convey multiple stacks of material at intervals along a first horizontal direction;

[0010] A vertical conveying mechanism, which is connected to the horizontal conveying mechanism, is used to receive stacks of materials one by one and convey the received stacks of materials in the vertical direction.

[0011] The stacking clamping mechanism is located at a preset stacking height on the vertical conveying mechanism and is configured to clamp the upper part of the stack from the side. When the stacking clamping mechanism clamps the upper part of the stack to form a sub-stack, the vertical conveying mechanism drives the unclamped part of the stack to descend, thereby forming a separation gap between the sub-stack and the unclamped part.

[0012] A bottom support mechanism is located below the stacking clamping mechanism and is configured to move to the bottom of the sub-stack to provide support after the separation gap is formed;

[0013] A feeding mechanism, disposed on the frame, is used to receive the sub-staples from the bottom support mechanism and output them.

[0014] Preferably, the stacking clamping mechanism includes a first driving member, a clamping member, and a first baffle, wherein the first baffle is disposed on the frame and is disposed opposite to the clamping member;

[0015] The first driving member is disposed on the frame and connected to the clamping member, and is configured to drive the clamping member to move in the horizontal direction so as to cooperate with the first baffle to clamp the stack of materials.

[0016] Preferably, the bottom support mechanism includes a second drive member disposed on the frame and a bottom support plate connected to the second drive member.

[0017] Preferably, the feeding mechanism includes a feeding drive assembly disposed on the frame and a picking member connected to the feeding drive assembly. The feeding drive assembly is configured to drive the picking member to move along a preset path to the bottom of the sub-stacking, and the picking member is provided with a clearance groove for avoiding the stacking clamping mechanism and the bottom support mechanism.

[0018] Preferably, the horizontal conveying mechanism includes:

[0019] Multiple conveyor belts and multiple profiles arranged alternately;

[0020] A horizontal conveying assembly is connected to multiple conveyor belts and configured to drive the multiple conveyor belts to rotate synchronously;

[0021] A lifting assembly, connected to multiple profiles, is configured to drive the multiple profiles to move vertically, so that the multiple profiles switch between a receiving state above multiple conveyor belts and receiving multiple stacks of material, and a discharging state below multiple conveyor belts.

[0022] Preferably, the length of the profile is less than the length of the conveyor belt;

[0023] The vertical conveying mechanism includes a support member for supporting the stack of materials, the support member having teeth that can extend into the gap between the two conveyor belts.

[0024] Preferably, the horizontal conveying mechanism further includes a first detection element, which is disposed between the profile and the vertical conveying mechanism and electrically connected to the lifting assembly.

[0025] Preferably, the lifting assembly includes:

[0026] A fixing plate is fixedly mounted on the frame;

[0027] A lifting cylinder is mounted on the fixed plate, and the piston rod of the lifting cylinder is arranged in the vertical direction.

[0028] A connecting plate is provided at the end of the piston rod of the lifting cylinder and is connected to all the profiles;

[0029] A buffer section, disposed between the fixed plate and the connecting plate, is configured to allow the piston rod of the lifting cylinder to extend and retract smoothly.

[0030] Preferably, the feeding and stacking device further includes a patting mechanism, which is directly opposite to the two side walls of the material stack supported by the vertical conveying mechanism along the second horizontal direction, and is configured to pat the material stack to align the material stack along the second horizontal direction, wherein the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0031] A feeding and stacking method based on the above-mentioned feeding and stacking device includes the following steps:

[0032] Step 1: Arrange multiple stacks of materials at intervals on the horizontal conveyor mechanism;

[0033] Step 2: The vertical conveyor receives the stacks of materials one by one, and after receiving the stacks, it can lift the top of the stacks to the first height position;

[0034] Step 3: The stacking clamping mechanism can clamp the upper part of the stack laterally to form sub-stacks;

[0035] Step 4: The vertical conveying mechanism lowers the height of the unclamped portion of the stack, creating a separation gap between it and the sub-stack;

[0036] Step 5: The bottom support mechanism is inserted into the separation gap and supports the bottom of the sub-staple;

[0037] Step Six: The feeding mechanism receives the sub-staples from the bottom support mechanism and outputs them;

[0038] Step 7: The vertical conveying mechanism lifts the top of the unclamped portion to the first height position and repeats steps 3 to 6 above;

[0039] Step 8: After the material stack on the vertical conveyor is loaded in several batches, the vertical conveyor receives the next material stack and repeats steps 3 to 6 above.

[0040] The beneficial effects of this invention are:

[0041] The feeding and stacking device and method proposed in this invention, under the action of a horizontal conveying mechanism and a vertical conveying mechanism, can position the upper part of one of the material stacks at a preset stacking height. A stacking clamping mechanism clamps the material stack to form a sub-stack. Subsequently, the unclamped portion descends, creating a separation gap between it and the sub-stack. A bottom-supporting mechanism inserts into the separation gap and supports the bottom of the sub-stack, preventing the materials in the sub-stack clamped by the stacking clamping mechanism from separating. Then, under the action of the feeding mechanism, the sub-stack is received, completing the feeding process. Compared to manual feeding, this feeding and stacking device can achieve automatic and continuous supply of material stacks and perform efficient and stable separation operations on each stack, reducing reliance on manual operation and improving the efficiency and stability of the stacking operation.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0057] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0058] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0060] Please see Figures 1 to 5This embodiment proposes a feeding and stacking device, which includes a frame 1, a horizontal conveying mechanism 2, a vertical conveying mechanism 3, a stacking clamping mechanism 4, a bottom support mechanism 5, and a feeding mechanism 6. The horizontal conveying mechanism 2 is disposed on the frame 1 and configured to carry and convey multiple stacks of material at intervals along a first horizontal direction. The vertical conveying mechanism 3 is connected to the horizontal conveying mechanism 2 and is used to receive stacks of material one by one and convey the received stacks of material along the vertical direction. The stacking clamping mechanism 4 is disposed on a preset position on the vertical conveying mechanism 3. At the stacking height, the upper part of the stack is clamped from the side. When the stacking clamping mechanism 4 clamps the upper part of the stack to form a sub-stack, the vertical conveying mechanism 3 drives the unclamped part of the stack to descend, thereby forming a separation gap between the sub-stack and the unclamped part. The bottom support mechanism 5 is located below the stacking clamping mechanism 4 and is configured to move to the bottom of the sub-stack to support it after the separation gap is formed. The feeding mechanism 6 is located on the frame 1 and is used to receive the sub-stack from the bottom support mechanism 5 and output it.

[0061] Understandably, under the action of the horizontal conveying mechanism 2 and the vertical conveying mechanism 3, the upper part of one of the stacks can be positioned at a preset stacking height. The stacking clamping mechanism 4 can clamp the stack to form a sub-stack. Subsequently, the unclamped portion descends, creating a separation gap between it and the sub-stack. The bottom support mechanism 5 inserts into the separation gap and supports the bottom of the sub-stack, preventing the materials in the sub-stack clamped by the stacking clamping mechanism 4 from separating. Then, the sub-stack is received by the feeding mechanism 6, completing the feeding process. Compared to manual feeding, this feeding and stacking device can achieve automatic and continuous supply of stacks and perform efficient and stable separation operations on each stack, reducing reliance on manual operation and improving the efficiency and stability of the stacking operation.

[0062] Based on the above, please refer to Figure 6 This embodiment also proposes a material feeding and stacking method, which includes the following steps:

[0063] Step 1: Arrange multiple stacks of materials at intervals on the horizontal conveyor mechanism 2;

[0064] Step 2: The vertical conveyor 3 receives the stacks of materials one by one, and after receiving the stacks, it can lift the top of the stacks to a first height position; wherein, the first height position is higher than the preset stacking height.

[0065] Step 3: The stacking clamping mechanism 4 can clamp the upper part of the stack laterally to form a sub-stack;

[0066] Step 4: The vertical conveyor mechanism 3 lowers the height of the unclamped portion of the material stack, creating a separation gap between it and the sub-stack;

[0067] Step 5: The bottom support mechanism 5 is inserted into the separation gap and supports the bottom of the sub-staple;

[0068] Step 6: The feeding mechanism 6 receives the sub-staples from the bottom support mechanism 5 and outputs them;

[0069] Step 7: The vertical conveying mechanism 3 lifts the top of the unclamped part to the first height position and repeats steps 3 to 6 above;

[0070] Step 8: After the material stack on the vertical conveyor 3 is loaded in several batches, the vertical conveyor 3 receives the next material stack and repeats steps 3 to 6 above.

[0071] Step 9: After all the material stacks on the horizontal conveyor 2 have been output, repeat steps 1 to 8 above.

[0072] Understandably, during the material feeding process, the operator only needs to place multiple stacks of material on the horizontal conveyor mechanism 2, and the remaining work can be completed by the material feeding and stacking device. This enables automatic and continuous feeding of material stacks and efficient and stable separation of each stack. It reduces the degree of manual involvement, lowers labor costs, and improves the efficiency and stability of the stacking operation.

[0073] In this embodiment, the stacking clamping mechanism 4 includes a first driving member 41, a clamping member 42, and a first baffle 43. The first baffle 43 is disposed on the frame 1 and is disposed opposite to the clamping member 42. The first driving member 41 is disposed on the frame 1 and connected to the clamping member 42, and is configured to drive the clamping member 42 to move horizontally to cooperate with the first baffle 43 to clamp the stack. It can be understood that when the stack is at a first height position, the vertical conveying mechanism 3 stops, the first driving member 41 drives the clamping member 42 to move closer to the first baffle 43 to clamp the stack, and then the vertical conveying mechanism 3 drives the stack to descend to realize the stacking of the stack.

[0074] In addition, a third detection element is installed at the first height position. The third detection element is electrically connected to the vertical conveying mechanism 3. After the stack is at the first height position, it can send a signal to the vertical conveying mechanism 3. After receiving the signal, the vertical conveying mechanism 3 stops to facilitate the start of stacking. The third detection element is preferably a photoelectric sensor as used in the prior art.

[0075] The bottom support mechanism 5 includes a second drive member 51 mounted on the frame 1 and a bottom support plate 52 connected to the second drive member 51. It is understood that after the material stack is divided into sub-stacks and a main stack, if the clamping force of the stacking clamping mechanism 4 on the sub-stack is too large, it can easily cause material deformation. Conversely, if the clamping force is too small, some material in the sub-stack may fall under its own weight. Therefore, after the vertical conveying mechanism 3 drives the material stack to descend, the second drive member 51 drives the bottom support plate 52 to insert between the sub-stack and the main stack, providing support for the sub-stack. This prevents insufficient clamping force of the stacking clamping mechanism 4 from causing some material in the sub-stack to fall under its own weight, thus ensuring that the feeding mechanism 6 does not collide with the material in the sub-stack when receiving it.

[0076] In this embodiment, the feeding mechanism 6 includes a feeding drive assembly 61 disposed on the frame 1 and a picking member 62 connected to the feeding drive assembly 61. The feeding drive assembly 61 is configured to drive the picking member 62 to move along a preset path to below the sub-staple, and the picking member 62 is provided with a clearance groove 621 for avoiding the stacking clamping mechanism 4 and the bottom support mechanism 5. It can be understood that after stacking is completed, the picking member 62 can move to below the sub-staple under the action of the feeding drive assembly to receive the sub-staple. Under the action of the first drive assembly 41, the clamping member 42 can move away from the sub-staple. Subsequently, under the action of the feeding drive assembly 61, the sub-staple can be lifted to a second height position higher than the first height position to facilitate its output. During the lifting process, the clearance groove 621 can prevent the picking member 62 from interfering with the stacking clamping mechanism 4 and the bottom support mechanism 5.

[0077] For example, the feeding drive assembly 61 includes a third drive member 611 and a fourth drive member 612. The third drive member 611 is disposed on the frame 1 and arranged in the vertical direction. The fourth drive member 612 is disposed at the drive end of the third drive member 611 and arranged in the horizontal direction. The picking member 62 is disposed at the drive end of the fourth drive member 612. Under the action of the third drive member 611 and the fourth drive member 612, the picking member 62 can move in the vertical and horizontal directions to complete the picking and feeding.

[0078] The material handling component 62 includes a vertically arranged connecting part and a material handling part. The connecting part is arranged in the vertical direction and is connected to the fourth driving component 612. Both the material handling part and the connecting part are provided with interconnected notches to form a clearance groove 621 to avoid the stacking clamping mechanism 4 and the bottom support mechanism 5. The thickness of the material handling part is less than the thickness of the bottom support plate 52 to avoid collision between the material handling part and the material and improve the feeding quality.

[0079] Among them, the first driving member 41, the second driving member 51, the third driving member 611 and the fourth driving member 612 are all preferably linear cylinders in the prior art. Of course, in some other feasible embodiments, they can also be other existing linear drive structures, such as linear electric cylinders, etc., which will not be described in detail here.

[0080] In this embodiment, the horizontal conveying mechanism 2 includes multiple conveyor belts 21 arranged alternately, multiple profiles 22, a horizontal conveying assembly 23, and a lifting assembly 24. The horizontal conveying assembly 23 is connected to the multiple conveyor belts 21 and is configured to drive the multiple conveyor belts 21 to rotate synchronously. The lifting assembly 24 is connected to the multiple profiles 22 and is configured to drive the multiple profiles 22 to move in the vertical direction, so that the multiple profiles 22 switch between a receiving state above the multiple conveyor belts 21 and receiving multiple stacks of material and a discharging state below the multiple conveyor belts 21. Understandably, when multiple profiles 22 are in the receiving state, their height is higher than the conveyor belt 21. Workers can arrange multiple stacks of material on the profiles 22 at intervals. Then, the lifting component 24 controls the profiles 22 to descend and switches from the receiving state to the discharging state. That is, during the descent of the profiles 22, the stacks of material can be transferred from the profiles 22 to the conveyor belt 21. Then, under the action of the horizontal conveying component 23, multiple conveyor belts 21 are driven to rotate synchronously to transport the stacks of material to the vertical conveying mechanism 3.

[0081] The horizontal conveying assembly 23 includes a drive wheel and a driven wheel. The conveyor belt 21 is wound between the drive wheel and the driven wheel. The drive wheel is connected to a rotary motor, which can drive the drive wheel to rotate under the action of the rotary motor, thereby driving the conveyor belt 21 to rotate.

[0082] Furthermore, the length of the profile 22 is less than the length of the conveyor belt 21; the vertical conveying mechanism 3 includes a support member 31 for supporting the stack of materials, the support member 31 having teeth 311 that can extend into the gap between the two conveyor belts 21. It is understood that after the stack of materials passes through the overlapping area of ​​the conveyor belt 21 and the profile 22, it can move to the overlapping area of ​​the conveyor belt 21 and the teeth 311 to complete the vertical conveying mechanism 3 receiving the stack of materials.

[0083] The vertical conveying mechanism 3 also includes a second baffle 32 disposed on the frame 1 and a vertical conveying assembly 33 that is drively connected to the bearing member 31. The second baffle 32 is disposed at the end of the horizontal conveying mechanism 2 to prevent the material stack from moving horizontally. The vertical conveying assembly 33 is arranged vertically and is located on the side of the second baffle 32 away from the horizontal conveying mechanism 2. The second baffle 32 is provided with a groove 321, and the top of the groove 321 is provided with an opening. The toothed part 311 is connected to the conveying end of the vertical conveying assembly 33 through the groove 321. The vertical conveying assembly 33 is preferably a ball screw conveying structure in the prior art, and no specific limitation is made here.

[0084] It should be noted that the first baffle 43 is also provided with a sliding groove 321, and the openings of the two sliding grooves 321 are arranged opposite each other so that the teeth 311 can move stably in the vertical direction. Furthermore, the two openings of the first baffle 43 and the second baffle 32 can be connected or the first baffle 43 and the second baffle 32 can be integrally formed.

[0085] The lifting assembly 24 includes a fixed plate 241, a lifting cylinder 242, a connecting plate 243, and a buffer section 244. The fixed plate 241 is fixedly mounted on the frame 1. The lifting cylinder 242 is mounted on the fixed plate 241, and its piston rod is arranged vertically. The connecting plate 243 is located at the end of the piston rod of the lifting cylinder 242 and is connected to all the profiles 22. The buffer section 244 is located between the fixed plate 241 and the connecting plate 243 and is configured to allow the piston rod of the lifting cylinder 242 to extend and retract smoothly. Under the action of the lifting cylinder 242, the connecting plate 243 can be pushed to move vertically, thereby simultaneously driving multiple profiles 22 to move vertically. During the movement, the buffer section 244 allows the piston rod of the lifting cylinder 242 to extend smoothly, preventing the material stack from becoming scattered due to the sudden extension of the piston rod.

[0086] Furthermore, the buffer section 244 includes two connecting shafts 2441, a mounting plate 2442, a first buffer member 2443, and a second buffer member 2444. One end of each of the two connecting shafts 2441 is connected to the connecting plate 243, and the other end has a through-hole through the fixing plate 241. The mounting plate 2442 is disposed below the fixing plate 241 and is connected to the two connecting shafts 2441. The first buffer member 2443 is disposed between the mounting plate 2442 and the fixing plate 241. The second buffer member 2444 is disposed between the fixing plate 241 and the connecting plate 243. It can be understood that when the profile 22 switches from the feeding state to the receiving state, the piston rod extends, driving the connecting plate 243 to rise. During this process, the first buffer member 2443 can slow down the rising speed of the piston rod. Conversely, when the profile 22 switches from the receiving state to the feeding state, the piston rod retracts, driving the connecting plate 243 to fall. During this process, the second buffer member 2444 can slow down the falling speed of the piston rod.

[0087] The first buffer 2443 and the second buffer 2444 are preferably ball plungers or compression springs in the prior art, and no specific limitation is made here.

[0088] Furthermore, the horizontal conveying mechanism 2 also includes a first detection element, which is disposed between the profile 22 and the vertical conveying mechanism 3 and electrically connected to the lifting assembly 24. It is understood that after one of the stacks leaves the area where the profile 22 is located, it passes the first detection element, which sends a signal to the lifting assembly 24. The lifting assembly 24 then switches the profile 22 from a feeding state to a receiving state, thereby lifting the stacks in the area where the profile 22 is located again to ensure that the stacks are conveyed to the vertical conveying mechanism 3 one by one. The first detection element is preferably a photoelectric sensor as used in the prior art, and no specific limitation is made here.

[0089] In addition, the horizontal conveying mechanism 2 also includes a second detection element and a blocking assembly 25. The second detection element is disposed at the junction of the horizontal conveying mechanism 2 and the vertical conveying mechanism 3 and is electrically connected to the vertical conveying mechanism 3. The blocking assembly 25 is disposed upstream of the second detection element and is electrically connected to the second detection element. It is configured to respond to the stack status detected by the second detection element and move from a clearance position to a blocking position to block the movement of the stack. It can be understood that when the stack moves to the carrier 31, the second detection element can send a signal to the blocking assembly 25, and then the blocking assembly 25 can move from the clearance position to the blocking position to prevent other stacks from entering the carrier 31, further ensuring that the vertical conveying mechanism 3 can receive a single stack.

[0090] The blocking component 25 includes two blocking plates 251 and a fifth driving member 252 connected to the two blocking plates 251. The two blocking plates 251 are located on both sides of the conveyor belt 21. After receiving the signal from the second detection member, the fifth driving member 252 can drive the two blocking plates 251 to rise to the blocking position. The fifth driving member 252 is preferably a linear cylinder in the prior art. Of course, in some other feasible embodiments, it can also be other existing linear drive structures, such as linear electric cylinders, etc., which will not be described in detail here.

[0091] In this embodiment, the feeding and stacking device further includes a tapping mechanism 7. The tapping mechanism 7 is directly opposite to the two side walls of the material stack supported on the vertical conveying mechanism 3 along the second horizontal direction, and is configured to tap the material stack to align it along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. This configuration ensures the alignment of the material stack in the second horizontal direction, while the alignment of the material stack in the first horizontal direction is adjusted by the clamping member 42 and the first baffle 43.

[0092] The material feeding mechanism 7 includes a material feeding component 71 and a limiting plate 72. The limiting plate 72 and the material feeding component 71 are arranged opposite each other along the second horizontal direction. When the material stack is in the bearing member 31, the material feeding component 71 can push the material stack closer to the limiting plate 72 to align the material stack.

[0093] The material tapping assembly 71 includes a sixth driving member 711 and a material tapping plate 712 disposed at the driving end of the sixth driving member 711. The length of the material tapping plate 712 is not less than the height of the material stack. The sixth driving member 711 is preferably a linear cylinder in the prior art. During the material tapping process, under the action of the linear cylinder, the material tapping plate 712 can be controlled to move back and forth so that the material tapping plate 712 can abut against the side wall of the material stack multiple times to ensure the quality of material tapping. After the material tapping is completed, the material tapping plate 712 can be reset under the action of the linear cylinder.

[0094] Furthermore, the clamping member 42 and the first baffle 43 are arranged opposite each other along the second horizontal direction, and the material tapping plate 712 and the limiting plate 72 are arranged opposite each other along the first horizontal direction, thereby enabling the circumference alignment of the material stack and improving the feeding quality.

[0095] To avoid the conveyor belt 21 affecting the material stack during the feeding process, the carrier 31 needs to be raised to the third height position before feeding. The third height position is lower than the preset stacking height, and the third height position is determined according to the height of the material stack, which will not be elaborated here.

[0096] In addition, the limiting plate 72 can extend to one side of the horizontal conveying mechanism 2, thereby preventing the horizontal conveying mechanism 2 from shifting when conveying the stack of materials.

[0097] It should be noted that during the feeding process, the stacking clamping mechanism 4, the bottom support mechanism 5, and the feeding mechanism 6 are all in their initial positions to avoid interference with the stack and to ensure the stability of the stack during the feeding process.

[0098] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
