Description

Technical Field

[0001] The invention relates to the technical field of warehousing and logistics equipment, and in particular to a logistics automated three-dimensional storage rack. Background Art

[0002] Logistics automated three-dimensional storage racks are a type of high-rise warehouse system that stores goods on multiple floors. It uses automated equipment and computer control systems to automatically store and retrieve goods. This type of storage rack is usually composed of shelves, aisle stackers, conveying systems, automatic control systems, and warehouse management software. In large e-commerce warehouses, automated three-dimensional storage racks can be tens of meters high and contain many rows of shelves. Each row of shelves has multiple layers of cargo space and can store a large number of goods.

[0003] The pallets used to carry goods are provided with fork holes for fork insertion. When the goods need to be transported, the stacker drives the fork to be inserted into the fork hole, and then the fork is lifted to lift the pallet for transportation. The end of the fork is usually narrow, and the side is in the shape of a trapezoid with one end high and the other end low. This shape facilitates the insertion operation;

[0004] In the actual storage and logistics environment, there will be a certain error in the position of the fork hole at the bottom of the cargo pallet, or there will be a certain angle deviation between the fork and the fork hole during the operation of the stacker. The narrower end can be like a "probe", making it easier to align with the fork hole, playing a role in guidance and preliminary positioning;

[0005] However, due to the unevenness of the top of the fork, after the fork is lifted, the center of gravity of the pallet will shift relative to the support plane of the fork. According to the characteristics of the center of gravity, the center of gravity of an object will tend to move closer to the lower side of the support plane under the action of gravity, causing the pallet and the goods to tilt together. Although the tilt angle is small, for some boxed goods wrapped in plastic film, the tilt of the pallet is likely to cause relative sliding between the goods, causing the film to stretch or even break. For individual goods that are not tightly fixed, such as small mechanical parts, they are also likely to move due to the tilt, increasing the risk of goods falling during transportation;

[0006] At present, the forks are all tilted for a long time. This is because if the forks are tilted for only a short time, although it can facilitate the insertion into the fork hole and extend the tilted part out of the pallet, since this part is relatively short, its tilt angle must be relatively large to have a sufficient guiding effect;

[0007] When the part with a larger inclined angle enters the fork hole, as the fork continues to go deeper, because the inclined part is short, before it completely enters the fork hole, the relatively higher part of the inclined part will quickly approach and contact the outer wall of the pallet or the edge of the fork hole. Once in contact, the force exerted on the pallet by the higher part of the fork is not vertically upward, but has a horizontal component force. This horizontal component force will push the pallet to move like pushing something;

[0008] In actual warehousing operations, the displacement of pallets is very disadvantageous, because changes in the position of the pallet will affect the stability of the goods on the pallet. Even a small displacement will cause the center of gravity of the pallet and the goods to change, thereby causing the previously mentioned risk of goods sliding, shifting or even falling, and will also affect subsequent operations such as handling and storage. Summary of the invention

[0009] The purpose of the present invention is to provide a logistics automated three-dimensional storage rack to solve the problems raised in the above background technology.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, the movable plate is trapezoidal as a whole when it moves toward the fork, and can be inserted into the fork hole at this time. The two ends of the elastic member are fixed and present a special surrounding structure. After the fork is inserted into the fork hole, the bent part of the elastic member moves with the adjusting rod and relies on the elastic force to lift the movable plate, so that the downwardly inclined end is pushed up, and the bulging degree of the elastic member is adaptively adjusted according to the weight of the goods to compensate for the problem of the tilt of the fork. The movable plate angle can also be changed by controlling the moving distance of the adjusting rod to stabilize the pallet so that the pallet can be parallel.

[0029] 2. In the present invention, the lower partition is provided with an arc end, which is frictionally adapted with the elastic member. When the elastic member bulges, it pushes the support block to tilt. The inclined support block lifts the upper right part of the elastic member, causing its right side to bulge relatively, and supports the right side of the elastic member, thereby improving its load-bearing effect on the movable plate.

[0030] 3. In the present invention, the elastic member is initially wound around the fixed rod in a roll shape. When the elastic member bulges and approaches the fixed rod, the elastic roll uses its own elastic recovery to wind back and expand under the partition to provide support for the elastic member, thereby preventing the elastic member from excessive deformation and strengthening the support for the movable plate, effectively ensuring the flatness of the pallet.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention provides a technical solution:

[0045] See also Figure 1-Figure 10 As shown, a logistics automated three-dimensional storage rack includes an automated three-dimensional storage rack body 1 and a pallet 2 for carrying goods. The pallet 2 is also provided with a fork hole 4 for inserting a fork 3. The automated three-dimensional storage rack body 1 is also provided with a stacker. One end of the fork 3 is connected to the stacker and the other end is gradually closed. The top and bottom are inclined surfaces. It also includes:

[0046] Two movable plates 5 are symmetrically arranged about the fork 3, one end of which is hinged to the fork 3, and the other end extends toward the closing direction of the fork 3. A notch 20 is provided at the closing of the fork 3;

[0047] A notch 20 is provided at the closing portion of the fork 3. The notch 20 is recessed inward to form a storage chamber 7. Two partitions 10 are symmetrically arranged on the side wall of the notch 20. The orthographic projections of the two partitions 10 toward the notch 20 are in the notch 20. One end of the two partitions 10 away from the storage chamber 7 extends toward the closing direction of the fork 3. A sliding opening 9 is left between the end of the partition 10 away from the closing portion of the fork 3 and the fork 3.

[0048] The adjusting rod 21 is horizontally movably arranged on the side wall of the notch 20 along the vertically symmetrical axis of the two partitions 10; the elastic member 6 is connected to the side wall of the storage chamber 7 at one end, and the other end is sequentially arranged around the upper partition 10, the adjusting rod 21, the lower partition 10, and connected to the side wall of the storage chamber 7. During the horizontal movement of the adjusting rod 21, the tension of the elastic member 6 is changed to support or separate from the two movable plates 5;

[0049] The storage chamber 7 is communicated with the notch 20, and the outer wall of the partition 10 is fixedly connected to the inner wall of the notch 20. The two partitions 10 correspond to the two inclined surfaces of the fork 3 respectively. One end of the elastic member 6 is fixedly connected to the inner top wall of the storage chamber 7, and the other end is fixedly connected to the inner bottom wall of the storage chamber 7. The outer wall of the elastic member 6 abuts against one end of the two partitions 10 located at the closing part of the fork 3, and the one side of the movable plate 5 corresponding to the fork 3 abuts against the area of ​​the elastic member 6 located outside the fork 3. The corner of the elastic member 6 is located between the two adjusting rods 21 and abuts against the outer wall of the adjusting rod 21.

[0050] The stacker on the main body 1 of the automated three-dimensional storage rack is used to drive the fork 3 to move so that the fork 3 can extend into the fork hole 4 of the pallet 2. When the stacker drives the fork 3 to lift upward, the fork 3 will drive the pallet 2 and the goods on the top of the pallet 2 to move together. The inclined surface of the fork 3 is at the upper and lower parts. Figure 3 as well as Figure 4 It can be seen in;

[0051] Next, Figure 4 From the perspective of:

[0052] Two parallel movable plates 5 correspond to the two inclined surfaces of the fork 3 respectively, and the outer wall of the movable plate 5 abuts against the inclined surface of the fork 3, one side of the movable plate 5 is located at the starting end of the inclined surface of the fork 3, and the other side of the movable plate 5 is close to the closing end of the inclined surface of the fork 3;

[0053] Both ends of the elastic member 6 are fixed in the storage chamber 7, one end of the elastic member 6 is fixedly connected to the inner top wall of the storage chamber 7, and the other end is fixedly connected to the inner bottom wall of the storage chamber 7. The remaining part of the elastic member 6 first extends to the inclined surface above the fork 3, that is, the top of the upper partition 10, through the two sliding openings 9. Then, the area of ​​the elastic member 6 located on the inclined surface above the fork 3 will abut against the outer wall of the fork hole 4, so that the fork hole 4 will not directly abut against the inclined surface of the fork 3.

[0054] After that, the elastic member 6 is located in the area of ​​the inclined surface above the fork 3 and extends to the closing part of the fork 3, and extends into the notch 20, that is, the area between the two partitions 10. Then, the elastic member 6 has a corner in the notch 20, that is, it turns in the notch 20 and then extends out of the notch 20. After extending out of the notch 20, the elastic member 6 goes around to the inclined surface below the fork 3, that is, the bottom of the lower partition 10, and finally re-extends into the storage chamber 7 through the lower sliding opening 9;

[0055] The elastic member 6 itself has elasticity, and can be made of a material that can recover after deformation, such as spring steel. The initial shape of the elastic member 6 is Figure 7 As shown in FIG. 2 , since both ends of the elastic member 6 are fixed, when the corner of the elastic member 6 is pulled toward the receiving chamber 7, the bulging parts of the upper and lower sides of the elastic member 6 will gradually retract into the notch 20, so that the area corresponding to the elastic member 6 and the partition 10 moves toward the partition 10, and then a Figure 4 The form in

[0056] When the elastic member 6 at the inclined surface of the fork 3 is close to the partition 10, the elastic member 6 does not bulge, and thus does not lift up the movable plate 5. At this time, the movable plate 5 abutting against the elastic member 6 is also very close to the inclined surface of the fork 3. The fork 3 and the movable plate 5 are still in an inclined state as a whole. At this time, the fork 3 can be inserted into the fork hole 4. After the fork 3 enters the fork hole 4, the two adjustment rods 21 clamped at the corners of the elastic member 6 move together toward the closing direction of the fork 3, gradually relaxing the tension on the elastic member 6, and then the area of ​​the elastic member 6 between the two partitions 10 will move toward the inclined surface of the fork 3 by its own elastic force, and the elastic member 6 will gradually bulge, and then the elastic member 6 will lift up the movable plate 5.

[0057] Since one end of the movable plate 5 is hinged to the fork 3, after the movable plate 5 is lifted up, the end of the movable plate 5 hinged to the fork 3 will swing, instead of the entire movable plate 5 moving upward. The bulging area of ​​the elastic member 6 not only pushes the movable plate 5 to be parallel, but can make the movable plate 5 tilt upward. This is because the weight of the pallet 2 and the goods on the pallet 2 will squeeze the movable plate 5, and since the bulging of the elastic member 6 is in a hollow state, the elastic member 6 will be pressed to bend. Therefore, the bulging degree of the elastic member 6 can push the movable plate 5 to exceed the parallel state or even tilt.

[0058] When the weight of the cargo is transferred to the movable plate 5 and the elastic member 6, the hollow portion of the elastic member 6 will be close to the partition 10, but the adjusting rod 21 can push the elastic member 6 more in the area inside the notch 20 outward, so that the elastic member 6 is more located on the inclined surface of the fork 3. Figure 7 From the perspective of the above, when the movable plate 5 squeezes the elastic member 6, the elastic member 6 pushes the movable plate 5 to tilt, that is, the end of the movable plate 5 close to the closing part of the fork 3 tilts upward. Since this part is relatively high, the weight will be first applied to the tilted end of the movable plate 5, so the gravity will also be preferentially applied to the right side of the bulging part of the elastic member 6. Then, the excess part of the elastic member 6 after being squeezed will tilt to the left, thereby causing the elastic member 6 to bulge near the squeezing block 19.

[0059] Back to Figure 4 From the perspective, since the position of the sliding opening 9 is closer to the hinged position of the movable plate 5 and the fork 3, the angle between the fork 3 and the movable plate 5 is smaller here, and then the elastic member 6 bulging near the sliding opening 9 will lift the movable plate 5 again. Therefore, even if the gravity of the movable plate 5 is applied to one position of the elastic member 6, the squeezed and contracted part will deform to the other side to support the movable plate 5, so that the movable plate 5 remains relatively flat, making up for the lack of support for the pallet 2 by the inclined part of the fork 3, so that the pallet 2 is relatively flat and more stable.

[0060] Since the distance between the adjusting rod 21 and the closing part of the fork 3 determines the bulging degree of the elastic member 6, the bulging degree of the elastic member 6 can be different by controlling the moving distance of the adjusting rod 21 by the automated three-dimensional storage rack body 1 itself, thereby making the movable plate 5 present different angles;

[0061] It is worth mentioning that the goods placed on the top of the pallet 2 here are not large machinery or some heavier goods. For example, if used in an e-commerce warehouse, the goods usually include clothing, small electronic products such as mobile phone accessories, headphones, etc., cosmetics, books and other various consumer goods. These goods are relatively light. The automated three-dimensional storage rack body 1 and the equipment in the automated storage system, such as stackers, conveyors, etc., need to be designed according to a certain load capacity and should not be used to transport overweight items. Moreover, the stacker relies on the fork 3 to lift the goods and the pallet 2, and the fork 3 is generally made of steel and has a very limited load-bearing capacity. Therefore, the elastic member 6 of the present application is sufficient to support the movable plate 5 and is within the weight-bearing range.

[0062] See also Figure 4-Figure 9 , and also includes two extrusion blocks 19, which are vertically corresponding to each other and are horizontally arranged at the closing part of the fork 3, and the two ends of the extrusion blocks 19 are fixedly installed with a rotating rod 18, and the end of the rotating rod 18 away from the extrusion block 19 is rotatably connected to the inner wall of the notch 20;

[0063] The end faces of both ends of the extrusion block 19 are elliptical, and the side of the extrusion block 19 that is farther from the rotating rod 18 abuts against the elastic member 6;

[0064] The fork 3 is also provided with two placement grooves 30 , which correspond vertically up and down. The rotating rods 18 at one end of the two extrusion blocks 19 extend into the two placement grooves 30 respectively. A servo motor 31 for driving the rotating rod 18 to rotate is arranged in the placement groove 30 .

[0065] exist Figure 4 and Figure 6 As can be seen in the figure, the end of the elastic member 6 that crosses the partition 10 has a bend, and when viewed separately Figure 4 In the figure, two extrusion blocks 19 correspond to the turning part of the partition 10, and the end surface of the extrusion block 19 is in an elliptical state, and the extrusion block 19 is supported on the notch 20 by two rotating rods 18, so that the extrusion block 19 is fixed here, and the servo motor 31 drives the rotating rod 18 to rotate, and then the extrusion block 19 can be driven to rotate through the rotating rod 18;

[0066] by Figure 4 From the perspective of , when the elastic member 6 is bulged outward, the area of ​​the elastic member 6 between the two partitions 10 will move outward, and at this time, the upper extrusion block 19 will rotate clockwise, and one side of the extrusion block 19 will protrude and be farther from the rotating rod 18, while the other side will be closer to the rotating rod 18. When the protruding side of the extrusion block 19 rotates to contact the elastic member 6, it will push the elastic member 6 to extend upward, while the lower extrusion block 19 will rotate counterclockwise and also push the elastic member 6 protruding downward, helping the elastic member 6 to extend outward;

[0067] Secondly, when the elastic member 6 stops bulging outward, the main body 1 of the automated three-dimensional storage rack controls the servo motor 31 to drive the rotating rod 18 to rotate, so that the protruding part of the extrusion block 19 rotates to abut against the elastic member 6. Since the protruding side of the extrusion block 19 will squeeze the elastic member 6, the extrusion block 19 abuts against it, preventing a part of the elastic member 6 from retracting into the notch 20 when the weight of the goods squeezes the elastic member 6.

[0068] When the protruding portion of the extrusion block 19 turns away from the elastic member 6, the remaining portion of the extrusion block 19 will not cause extrusion to the elastic member 6. When a partial area of ​​the elastic member 6 is pulled back between the two partitions 10, the extrusion block 19 can also rotate in the opposite direction to help push the elastic member 6 into between the two partitions 10. A blocking block 17 is also fixedly installed on the inner wall of the notch 20. The blocking block 17 is located between the two turning parts of the elastic member 6 and is used to separate the two turning parts of the elastic member 6. When the protruding portion of the extrusion block 19 pushes the turning part of the elastic member 6, it will scratch the edge of the blocking block 17, such as Figure 4It can be seen that the outer periphery of the bend of the elastic member 6 is tilted outward at the edge of the blocking block 17, so that when the protruding portion of the extrusion block 19 reaches here, it is easier to push this part of the elastic member 6 to move toward the inclined surface of the fork 3.

[0069] See also Figure 3-Figure 9 , further comprising a support block 16, which is arranged in the notch 20, the length of the partition 10 above the adjusting rod 21 is shorter than the length of the partition 10 below the adjusting rod 21, so that there is a gap between the end of the upper partition 10 away from the storage chamber 7 and the closing part of the fork 3, and the support block 16 is located in the gap, and both ends of the support block 16 are against the inner wall of the notch 20;

[0070] The inner wall of the support block 16 is fixedly mounted with a rotating shaft 15, both ends of which extend to the outside of the support block 16 and are rotatably connected to the inner wall of the notch 20;

[0071] The support block 16 is also penetrated by an arcuate through groove 28, which extends along the axial direction of the support block 16, and is connected to the outside at both ends. There is a spacing between the arcuate through groove 28 and the rotating shaft 15. The left and right symmetrical sides of the support block 16 are both set as arcuate surfaces. A transversely arranged limit rod 29 is provided in the arcuate through groove 28, and the two ends of the limit rod 29 are respectively fixedly connected to the two inner walls of the notch 20. When the inner top wall of the arcuate through groove 28 abuts against the limit rod 29, the two arcuate surfaces of the support block 16 are on the same horizontal line, and the elastic member 6 abuts against the arcuate surface of the support block 16 close to the arcuate through groove 28.

[0072] Depend on Figure 6 From the perspective of FIG, one end of the lower partition 10 is provided with an arc end 11, and the arc end 11 is located at the closing position of the fork 3. The length of the upper partition 10 is shorter than that of the lower partition 10. When the elastic member 6 is wound toward the bottom of the lower partition 10, the elastic member 6 abuts against the outer wall of the arc end 11. Therefore, when the elastic member 6 bulges or contracts, the outer wall of the elastic member 6 will rub against the outer wall of the arc end 11, while the end of the upper partition 10 located at the closing position of the fork 3 does not contact the elastic member 6, and abuts against the outer wall of the elastic member 6 through the support block 16.

[0073] exist Figure 6In this perspective, the inner top wall of the arc-shaped through groove 28 is against the limit rod 29, the limit rod 29 is fixed, and the outer wall of the elastic member 6 is against the arc surface on the right side of the support block 16. When the elastic member 6 bulges, a part of the elastic member 6 in the notch 20 moves outward, and the elastic member 6 will rub the support block 16 when moving, and exert an upward force on the end of the support block 16 away from the rotating shaft 15, and then the support block 16 will rotate along the inner wall of the notch 20 through the rotating shaft 15 until it rotates to the inner bottom wall of the arc-shaped through groove 28 and the limit rod 29. At this time, the end of the support block 16 away from the rotating shaft 15 will be in the upper right, and the overall support block 16 is in a tilted state. Figure 7 From the perspective of;

[0074] After the support block 16 is tilted, it supports the upper right side of the bend of the elastic member 6, so that the part of the elastic member 6 close to the closing of the fork 3 bulges, so that when one end of the closing of the movable plate 5 squeezes the bulging elastic member 6 at the closing, the bulging part of the elastic member 6 can be more easily pushed to the left. The cooperation of the arc-shaped through groove 28 and the limiting rod 29 limits the inclination of the support block 16, and avoids the inclination of the support block 16 to a large extent that the elastic member 6 cannot be pulled back to its original position when it is retracted again. When the elastic member 6 is retracted and the inner top wall of the arc-shaped through groove 28 is against the limiting rod 29, the angle of the support block 16 is more in line with the inclined surface of the fork 3. When the support block 16 is tilted, the arc-shaped surface on the right side of the support block 16 tilts upward, and at this time it will protrude from the inclined surface of the fork 3 and support the movable plate 5.

[0075] See also Figure 4-Figure 8 , further comprising a fixing rod 13, the fixing rod 13 being located above the shorter partition 10 and being located on one side of the support block 16, an elastic roll 14 being wound around the fixing rod 13, one end of the elastic roll 14 being fixedly connected to the outer wall of the fixing rod 13, and the other end of the elastic roll 14 passing through the gap between the partition 10 and the support block 16 and being fixedly connected to the outer wall of the elastic member 6;

[0076] One side wall of the elastic roll 14 abuts against one end of the partition plate 10 , and the other side abuts against the arc surface of the support block 16 close to the rotating shaft 15 .

[0077] The two ends of the fixing rod 13 are rotatably connected to the inner walls of the two sides of the notch 20, respectively. The elastic coil 14 can be made of the same material as the elastic member 6. The initial state of the elastic coil 14 is rolled around the fixing rod 13, just like a steel coil. One end of the elastic coil 14 is fixedly connected to the outer wall of the elastic member 6. Figure 6In this state, the elastic member 6 is in a contracted state, and the portion where the elastic member 6 is connected to the elastic roll 14 is far from the fixed rod 13, so the elastic roll 14 is pulled apart. When the elastic member 6 swells, the portion where the elastic member 6 is connected to the elastic roll 14 will gradually approach the fixed rod 13, and the elastic roll 14 will gradually wind back to the fixed rod 13 by its own elastic recovery effect, and the fixed rod 13 will also rotate while winding back.

[0078] As the elastic roll 14 is located in the area below the partition 10 and wraps around the fixed rod 13, the elastic roll 14 gradually expands and supports the elastic member 6. An arc groove 12 is also provided on the upper partition 10 to hold the elastic roll 14 and provide space for the expansion of the elastic roll 14. After the elastic roll 14 expands, it lifts up the elastic member 6. In this way, when the gravity of the movable plate 5 squeezes the elastic member 6, the elastic member 6 can be squeezed on the elastic roll 14. Since the elastic roll 14 is rolled up, the elastic roll 14 is a solid. After the elastic member 6 is squeezed and its outer wall presses against the elastic roll 14, the elastic member 6 will no longer continue to deform and close to the outer wall of the partition 10. The support of the elastic roll 14 can further ensure the supporting force of the elastic member 6 on the movable plate 5, and also make the movable plate 5 more supporting, thereby ensuring the flatness of the tray 2.

[0079] See also Figure 4-Figure 6 The driving member further includes a hydraulic rod 24, which is located in the storage chamber 7, and the telescopic end of the hydraulic rod 24 is fixedly connected to the outer wall of one of the adjustment rods 21, and a connecting rod 23 is fixedly connected between the adjacent ends of the two adjustment rods 21, and the outer wall of the connecting rod 23 is against the inner wall of the notch 20;

[0080] The outer wall of the adjustment rod 21 connected to the hydraulic rod 24 is fixedly connected with an elastic plate 22, the top and bottom ends of the elastic plate 22 are respectively against the upper and lower partitions 10, and the side of the elastic plate 22 away from the adjustment rod 21 is against the outer wall of the elastic member 6;

[0081] Two transversely arranged mounting plates 8 are fixedly mounted on the inner wall of the storage chamber 7 , and the hydraulic rod 24 is located between the two mounting plates 8 . The fixed end of the hydraulic rod 24 is fixedly connected to the inner wall of the storage chamber 7 , and the outer wall thereof abuts against the outer wall of the storage chamber 7 .

[0082] The hydraulic rod 24 is fixed in the storage chamber 7 and is used to drive the adjustment rod 21 to move, so as to achieve the effect of moving the two adjustment rods 21. The upper and lower ends of the elastic plate 22 are both against the two partitions 10, which can ensure that when the adjustment rod 21 pushes the bending part of the elastic member 6, the elastic member 6 will not overflow in the direction of the hydraulic rod 24, so that the elastic member 6 can only move toward the closing part of the fork 3;

[0083] The two mounting plates 8 provide further support for the hydraulic rod 24, making the hydraulic rod 24 more firm and stable, and the system of the automated three-dimensional storage rack body 1 itself can control the opening and closing of the hydraulic rod 24. The automated three-dimensional storage rack body 1 sends signals to the control unit of the hydraulic system. This control unit is like a "brain" that can interpret these signals and convert them into operating instructions for components such as hydraulic pumps and hydraulic valves.

[0084] See also Figure 4 and Figure 5 One end of the sliding opening 9 away from the storage chamber 7 extends obliquely toward the closing direction of the fork 3 until it is connected to the outside of the fork 3.

[0085] After the bulging elastic member 6 is squeezed by the weight on the movable plate 5, a partial area of ​​the elastic member 6 will accumulate at the position of the sliding opening 9, and the closing end of the sliding opening 9 is close to the outer wall of the elastic member 6. In this way, when the portion of the elastic member 6 close to the sliding opening 9 bulges, the outer wall of the bulging portion of the elastic member 6 will be stuck at the closing end of the sliding opening 9. As for why the sliding opening 9 is arranged at an angle, this is to ensure that when the elastic member 6 extends out through the sliding opening 9, the elastic member 6 itself will not be bent at an excessively large angle, which can increase the service life of the elastic member 6 and prevent the elastic member 6 itself from having more serious bending marks, thereby further ensuring the elastic recovery function of the elastic member 6.

[0086] See also Fig.10 The fork 3 is provided with two receiving grooves 26, which correspond to each other vertically. The two receiving grooves 26 correspond to the sides of the two movable plates 5 away from the notch 20 respectively. A spring hinge 27 is hinged between the outer wall of the movable plate 5 and the inner bottom wall of the receiving groove 26, and the spring hinge 27 is located at the edge of the inclined surface of the fork 3.

[0087] The top of the accommodating groove 26 is the height of the movable plate 5 after being leveled. The movable plate 5 is hinged to the fork 3 through a spring hinge 27. The spring hinge 27 can continuously apply a force to the movable plate 5 to make the movable plate 5 close to the partition 10, so that the movable plate 5 can be tilted in the initial state and be in a tilted state together with the fork 3, which is convenient for insertion into the fork hole 4.

[0088] See also Fig. 9 The servo motor 31 is fixedly mounted on the inner bottom wall of the placement slot 30, and the driving end of the servo motor 31 is fixedly connected to one end of the rotating rod 18 extending to the inside of the placement slot 30. An embedding slot 25 is provided on one side of the fork 3, and the embedding slot 25 extends along the axial direction of the fork 3. One end of the embedding slot 25 is close to the placement slot 30 and is connected to the two placement slots 30.

[0089] The embedding groove 25 is a channel for placing the circuit for energizing the servo motor 31. The power transmission line can be connected to the stacker through the embedding groove 25, and it is convenient to drive the controllable servo motor 31. As for the power supply channel of the hydraulic rod 24, the hydraulic rod 24 is already inside the fork 3, and the fork 3 is directly connected to the stacker, so the hydraulic rod 24 inside the fork 3 can be directly energized.
