Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warehouse logistics equipment, in particular to a logistics automated stereoscopic storage rack. BACKGROUND

[0002] The logistics automated stereoscopic storage rack is a multi-layer storage goods high-bay warehouse system, which uses automatic equipment and computer control system to realize automatic storage and retrieval of goods; such a storage rack is usually composed of shelves, roadway type stacker, conveying system, automatic control system and warehouse management software, and in a large e-commerce warehouse, the automated stereoscopic storage rack can be as high as dozens of meters, containing many rows of shelves, each row of shelves has multiple layers of goods, and can store a large amount of goods.

[0003] A fork hole is provided on the pallet for carrying goods for the insertion of a fork, and then when the goods need to be transported, the stacker drives the fork to insert into the fork hole, and then the fork lifts to lift the pallet for transportation. The end of the fork is usually narrow, and the side presents a trapezoidal shape with one end high and one end low. Such an appearance helps the insertion operation.

[0004] In the actual warehouse logistics environment, there will be some errors in the position of the fork hole at the bottom of the goods pallet, or there will be some angular deviation between the fork and the fork hole during the operation of the stacker. The narrow end can act like a "probe" and be more easily aligned with the fork hole, playing a guiding and preliminary positioning role.

[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, under the action of gravity, the center of gravity will tend to be closer to the lower side of the support plane, and thus the pallet will tilt together with the goods. Although the angle of inclination is very small, for some box goods wrapped with plastic film, the tilting of the pallet can cause relative sliding between the goods, stretching or even breaking the film. For single goods that are not tightly fixed, such as small mechanical parts, they can also be displaced due to tilting, increasing the risk of goods falling during transportation.

[0006] The current fork is in an inclined state for a long time. This is because if the fork is only inclined for a small part, it can facilitate insertion into the fork hole and also extend the inclined part outside the pallet, but since this part is relatively short, its inclination angle must be relatively large in order to have sufficient guiding effect.

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

[0008] In actual warehousing operations, pallet displacement is very detrimental because changes in pallet position affect the stability of goods on the pallet. Even a small displacement can cause the center of gravity of the pallet and goods to change, leading to the aforementioned risks of goods sliding, shifting, or even falling. It will also affect a series of subsequent handling, storage, and other operations. Summary of the Invention

[0044] The application provides a technical solution:

[0045] Referring to Figures 1-10 The figure shows a logistics automatic three-dimensional storage rack, which comprises an automatic three-dimensional storage rack main body 1 and a tray 2 for carrying goods. The tray 2 is also provided with a fork hole 4 for inserting a fork 3. The automatic three-dimensional storage rack main body 1 is also provided with a stacker. One end of the fork 3 is connected with the stacker, and the other end is gradually tapered. The top and bottom are inclined surfaces. The automatic three-dimensional storage rack main body 1 further comprises

[0046] Two movable plates 5 are symmetrically arranged above and below the fork 3, one end of each movable plate 5 is hingedly connected to the fork 3, and the other end of each movable plate 5 extends towards the closing direction of the fork 3, and a notch 20 is formed at the closing end of the fork 3;

[0047] The notch 20 is formed at the closing end of the fork 3, the notch 20 is recessed to form a receiving cavity 7, two partitions 10 are symmetrically arranged on the side wall of the notch 20, the normal projection of the two partitions 10 towards the notch 20 is in the notch 20, and the end of each partition 10 away from the receiving cavity 7 extends towards the closing direction of the fork 3, and a sliding opening 9 is left between the end of each partition 10 away from the closing end of the fork 3 and the fork 3;

[0048] An adjusting rod 21 is horizontally movably arranged on the side wall of the notch 20 along the axis symmetrically arranged above and below the two partitions 10, and an elastic member 6 is connected to the side wall of the receiving cavity 7 at one end and connected to the side wall of the receiving cavity 7 at the other end after being sequentially arranged behind the upper partition 10, the adjusting rod 21 and the lower partition 10, and the tension of the elastic member 6 is changed to support or disengage the two movable plates 5 during the horizontal movement of the adjusting rod 21;

[0049] The receiving cavity 7 is in communication with the notch 20, the outer wall of each 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 receiving cavity 7, the other end of the elastic member 6 is fixedly connected to the inner bottom wall of the receiving cavity 7, the outer wall of the elastic member 6 abuts against the end of each partition 10 located at the closing end of the fork 3, the surface of each movable plate 5 corresponding to the fork 3 abuts against the area of the elastic member 6 located outside the fork 3, and 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 automated stereoscopic storage rack body 1 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 has two parts, which can be seen in Figure 3 and Figure 4 ;

[0051] Next, the perspective of Figure 4 will be described first:

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

[0053] The two ends of the elastic member 6 are fixed in the receiving chamber 7, one end of the elastic member 6 is fixedly connected with the inner top wall of the receiving chamber 7, and the other end is fixedly connected with the inner bottom wall of the receiving chamber 7, the remaining part of the elastic member 6 first extends to the inclined surface above the fork 3 through the two sliding openings 9, that is, the top of the upper partition plate 10, and then the region of the elastic member 6 above the inclined surface of the fork 3 abuts against the outer wall of the fork hole 4, so that the fork hole 4 does not directly abut against the inclined surface of the fork 3;

[0054] Then the region of the elastic member 6 above the inclined surface of the fork 3 extends to the closed end of the fork 3 and extends into the gap 20, that is, the region between the two partition plates 10, and then the elastic member 6 has a corner in the gap 20, that is, the elastic member 6 extends out of the gap 20 after turning in the gap 20, and then the elastic member 6 extends out of the gap 20 and winds around the inclined surface below the fork 3, that is, the bottom of the lower partition plate 10, and finally extends into the receiving chamber 7 through the lower sliding opening 9;

[0055] The elastic member 6 itself has elasticity and can be made of spring steel or other materials that can deform and recover, and the initial shape of the elastic member 6 is Figure 7 As shown in FIG. 6, since the two ends of the elastic member 6 are fixed, when the corner of the elastic member 6 is pulled to move in the direction of the receiving chamber 7, the parts on the upper and lower sides of the elastic member 6 will gradually retract into the gap 20, so that the region of the elastic member 6 corresponding to the partition plate 10 approaches the partition plate 10, and then the shape shown in FIG. 7 is formed; Figure 4

[0056] When the elastic member 6 close to the partition plate 10 on the inclined surface of the fork 3, the elastic member 6 does not bulge, so the movable plate 5 is not lifted, and the movable plate 5 abutting against the elastic member 6 is also close to the inclined surface of the fork 3 at this time, and the whole fork 3 and the movable plate 5 are still in an inclined state, 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 adjusting rods 21 clamping the corner of the elastic member 6 move together in the direction of the closed end of the fork 3, gradually relaxing the pulling force on the elastic member 6, and then the region of the elastic member 6 between the two partition plates 10 will move to 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 the movable plate 5;

[0057] Since one end of the movable plate 5 is hinged to the fork 3, when the movable plate 5 is lifted, the end of the movable plate 5 hinged to the fork 3 will swing, rather than the whole movable plate 5 moving upward, and the region of the elastic member 6 bulging is not only to lift the movable plate 5 to be parallel, but also to make the movable plate 5 tilt upward, because the weight of the pallet 2 and the goods on the pallet 2 will press the movable plate 5, and since the elastic member 6 bulges in a hollow state, the elastic member 6 will be pressed to bend, so the degree of the elastic member 6 bulging can lift the movable plate 5 to be more than parallel or even tilted; ​

[0058] When the weight of the goods is transferred to the movable plate 5 and the elastic element 6, the hollow part of the elastic element 6 will be closer to the partition plate 10. However, the adjusting rod 21 can push more of the area of ​​the elastic element 6 within the notch 20 outward, so that more of the elastic element 6 is located on the inclined surface of the fork 3. Next, let's take... Figure 7 As you can see, when the movable plate 5 presses against the elastic element 6, the elastic element 6 pushes the movable plate 5 to tilt, that is, the end of the movable plate 5 near the fork 3 retraction part tilts upward. Since this part is relatively high, the weight will be applied to the tilted end of the movable plate 5 first. Therefore, the gravity will also be applied to the right side of the bulging part of the elastic element 6 first. Then, after the elastic element 6 is compressed, the excess part will tilt to the left, which will cause the elastic element 6 to bulge near the pressing block 19.

[0059] Back to Figure 4 From the perspective, since the sliding opening 9 is closer to the hinge between the movable plate 5 and the fork 3, the angle between the fork 3 and the movable plate 5 is smaller at this point. Then, the elastic element 6 that bulges near the sliding opening 9 will push up the movable plate 5 again. Therefore, even if the weight of the movable plate 5 is applied to one position on the elastic element 6, the squeezed and contracted part will deform to the other side to support the movable plate 5, keeping the movable plate 5 in a relatively flat state. This compensates for the lack of support for the pallet 2 by the tilted part of the fork 3, making the pallet 2 relatively flat and more stable.

[0060] Since the distance between the adjusting rod 21 and the fork 3 retraction point determines the degree of bulging of the elastic element 6, the moving distance of the adjusting rod 21 can be controlled by the main body 1 of the automated storage rack itself, so that the degree of bulging of the elastic element 6 is different, and thus the movable plate 5 presents different angles.

[0061] It is worth noting that the goods placed on top of pallet 2 here are not large machinery or heavy goods. For example, if applied to e-commerce warehouses, the goods usually include clothing, small electronic products such as mobile phone accessories and headphones, cosmetics, books and other consumer goods. These goods are relatively light. The main body 1 of the automated storage and retrieval system and the equipment in the automated storage system, such as stacker cranes and conveyors, need to be designed according to certain load-bearing capacity and are not suitable for transporting excessively heavy items. Moreover, the stacker crane relies on forks 3 to lift goods and pallet 2, and forks 3 are generally made of steel with very limited load-bearing capacity. Therefore, the elastic element 6 of this application is sufficient to support the movable plate 5 within the weight-bearing range.

[0062] See Figures 4-9 It also includes two pressing blocks 19, which are vertically aligned and horizontally positioned at the end of the fork 3. Both ends of the pressing blocks 19 are fixedly mounted with rotating rods 18, and the end of the rotating rod 18 away from the pressing blocks 19 is rotatably connected to the inner wall of the notch 20.

[0063] The end face of the extrusion block 19 at both ends is oval, and the side of the extrusion block 19 far from the rotating rod 18 is in contact with the elastic member 6;

[0064] The fork 3 is also provided with two placing grooves 30 vertically corresponding to each other, and the rotating rod 18 of one end of the two extrusion blocks 19 respectively extends into the two placing grooves 30, and the placing grooves 30 are provided with a servo motor 31 for driving the rotating rod 18 to rotate.

[0065] In Figure 4 and Figure 6 , it can be seen that one end of the elastic member 6 beyond the partition plate 10 has a bend, and separately looking at Figure 4 , the two extrusion blocks 19 correspond to the bend of the partition plate 10, and the end face of the extrusion block 19 is oval, and the extrusion block 19 is supported on the notch 20 by the two rotating rods 18, so that the extrusion block 19 is fixed there, and after the servo motor 31 drives the rotating rod 18 to rotate, the extrusion block 19 can be driven to rotate through the rotating rod 18;

[0066] From the perspective of Figure 4 , when the elastic member 6 is bulged outward, the area of the elastic member 6 between the two partition plates 10 will move outward, at this time, the upper extrusion block 19 rotates clockwise, one side of the extrusion block 19 protrudes, far from the rotating rod 18, and the other side is close 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 stretch upward, and the lower extrusion block 19 rotates counterclockwise and also pushes the downward protruding elastic member 6 to help the elastic member 6 to extend outward;

[0067] Secondly, when the elastic member 6 stops bulging outward, the automatic three-dimensional storage rack main body 1 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 be in contact with the elastic member 6, because the protruding side of the extrusion block 19 will extrude the elastic member 6, so the extrusion block 19 will resist it, avoiding the weight of the goods from extruding the elastic member 6, part of the area of the elastic member 6 retracts into the notch 20;

[0068] When the protruding part of the extrusion block 19 rotates away from the elastic member 6, the remaining part of the extrusion block 19 will not extrude the elastic member 6, when part of the area of the elastic member 6 is pulled back between the two partition plates 10, the extrusion block 19 can also rotate reversely to help the elastic member 6 to push into between the two partition plates 10, and the blocking block 17 is fixedly installed on the inner wall of the notch 20, the blocking block 17 is located between the two bends of the elastic member 6, and is used to separate the two bends of the elastic member 6, and when the protruding part of the extrusion block 19 pushes the bend of the elastic member 6, it will draw the edge of the blocking block 17, as Figure 4As can be seen, the outer periphery of the elbow of the elastic member 6 is raised outward at the edge of the blocking block 17, so that when the protruding part of the pressing block 19 reaches here, it is easier to push the part of the elastic member 6 to move to the inclined surface of the fork 3.

[0069] Referring to Figures 3-9 Further comprising, the support block 16 is arranged in the gap 20, the length of the upper partition plate 10 above the adjusting rod 21 is shorter than the length of the lower partition plate 10 below the adjusting rod 21, so that there is a gap between the end of the upper partition plate 10 away from the receiving chamber 7 and the closed end of the fork 3, and the support block 16 is located in the gap, and both ends of the support block 16 abut against the inner wall of the gap 20;

[0070] The inner wall of the support block 16 is fixedly installed with the rotating shaft 15, both ends of the rotating shaft 15 extend to the outside of the support block 16 and are rotationally connected with the inner wall of the gap 20;

[0071] The support block 16 is also provided with an arc-shaped through slot 28, the arc-shaped through slot 28 extends along the axial direction of the support block 16, both ends of the arc-shaped through slot 28 are in communication with the outside, there is a gap between the arc-shaped through slot 28 and the rotating shaft 15, both sides of the support block 16 are arc-shaped surfaces, the arc-shaped through slot 28 is provided with a transversely arranged limiting rod 29, both ends of the limiting rod 29 are fixedly connected with the inner walls of the two sides of the gap 20, when the inner top wall of the arc-shaped through slot 28 abuts against the limiting rod 29, the two arc-shaped surfaces of the support block 16 are on the same horizontal line, and the elastic member 6 abuts against the arc-shaped surface of the support block 16 close to the arc-shaped through slot 28.

[0072] From the perspective of Figure 6 The end of the lower partition plate 10 is provided with a circular arc end 11, the circular arc end 11 is located at the closed end of the fork 3, the length of the upper partition plate 10 is shorter than the length of the lower partition plate 10, when the elastic member 6 winds around the bottom of the lower partition plate 10, the elastic member 6 abuts against the outer wall of the circular arc end 11, so that when the elastic member 6 is inflated or deflated, the outer wall of the elastic member 6 will rub against the outer wall of the circular arc end 11, and the end of the upper partition plate 10 at the closed end of the fork 3 does not contact the elastic member 6, and the outer wall of the elastic member 6 abuts against the support block 16;

[0073] In Figure 6In this perspective, the inner top wall of the arc-shaped through slot 28 is in abutment with the limiting rod 29, the limiting rod 29 is fixed, and the outer wall of the elastic member 6 is in abutment with the arc-shaped surface on the right side of the support block 16. When the elastic member 6 is inflated, the partial area of the elastic member 6 in the gap 20 moves outward, and the elastic member 6 rubs against the support block 16 when moving and exerts an upward force on the end of the support block 16 away from the rotating shaft 15. Then the support block 16 rotates along the inner wall of the gap 20 through the rotating shaft 15 until the inner bottom wall of the arc-shaped through slot 28 is in abutment with the limiting rod 29. At this time, the end of the support block 16 away from the rotating shaft 15 is on the right upper side, and the overall support block 16 is in an inclined state. This state can be seen from the perspective of Figure 7 ;

[0074] After the support block 16 is inclined, it supports the right upper side of the bend of the elastic member 6, causing the part of the elastic member 6 close to the closing part of the fork 3 to inflate. In this way, when the end of the movable plate 5 at the closing part presses the inflated elastic member 6 at the closing part, it can more easily push the inflated part of the elastic member 6 to the left side. The cooperation of the arc-shaped through slot 28 and the limiting rod 29 limits the inclination of the support block 16, avoiding the situation that if the inclination of the support block 16 is too large, the elastic member 6 cannot pull the support block 16 back to the original position when it retracts. In the retracted state of the elastic member 6, and when the inner top wall of the arc-shaped through slot 28 is in abutment with the limiting rod 29, the angle of the support block 16 at this time is more consistent with the inclined surface of the fork 3. When the support block 16 is inclined, the arc-shaped surface on the right side of the support block 16 is raised upward, which will protrude from the inclined surface of the fork 3 and support the movable plate 5.

[0075] Referring to Figures 4-8 , it also includes a fixed rod 13 located above the shorter partition plate 10 and on one side of the support block 16. An elastic roll 14 is wound around the fixed rod 13. One end of the elastic roll 14 is fixedly connected to the outer wall of the fixed rod 13, and the other end is fixedly connected to the outer wall of the elastic member 6 through the gap between the partition plate 10 and the support block 16.

[0076] One side wall of the elastic roll 14 is in abutment with one end of the partition plate 10, and the other side is in abutment with the arc-shaped surface on the support block 16 close to the rotating shaft 15.

[0077] The two ends of the fixed rod 13 are respectively rotatably connected to the inner walls of the two sides of the gap 20. The elastic roll 14 can be made of the same material as the elastic member 6. The initial state of the elastic roll 14 is to be wound in a roll shape on the fixed rod 13, like a steel roll. One end of the elastic roll 14 is fixedly connected to the outer wall of the elastic member 6, and the other end is fixedly connected to the outer wall of the elastic member 6 through the gap between the partition plate 10 and the support block 16. Figure 6When the elastic piece 6 is in the state, the elastic piece 6 is in a contracted state, and the part where the elastic piece 6 is connected with the elastic roll 14 is far away from the fixed rod 13, so the elastic roll 14 is pulled open. When the elastic piece 6 is inflated, the part where the elastic piece 6 is connected with the elastic roll 14 gradually approaches the fixed rod 13, and the elastic roll 14 gradually winds back on the fixed rod 13, and the fixed rod 13 also rotates at the same time;

[0078] With the winding of the elastic roll 14 on the fixed rod 13, the elastic roll 14 gradually expands and supports the elastic piece 6. The arc-shaped slot 12 is also provided on the upper partition plate 10, which is used for containing the elastic roll 14 and providing space for the expansion of the elastic roll 14. After the expansion of the elastic roll 14, the elastic piece 6 is lifted up. Thus, when the elastic piece 6 is pressed by the gravity of the movable plate 5, the elastic piece 6 can be pressed on the elastic roll 14. Since the elastic roll 14 is wound, the elastic roll 14 is a solid body. When the outer wall of the elastic piece 6 is pressed on the elastic roll 14 after being pressed, the elastic piece 6 will not continue to deform and approach the outer wall of the partition plate 10. The support of the elastic roll 14 can further ensure the support force of the elastic piece 6 on the movable plate 5, and the movable plate 5 has more support force, which ensures the flatness of the tray 2.

[0079] Referring to Figures 4-6 The driving piece further comprises a hydraulic rod 24, which is located in the receiving chamber 7. The telescopic end of the hydraulic rod 24 is fixedly connected with the outer wall of one of the adjusting rods 21. The two adjusting rods 21 are fixedly connected with a connecting rod 23 at the adjacent end. The outer wall of the connecting rod 23 abuts against the inner wall of the notch 20.

[0080] The outer wall of the adjusting rod 21 connected with the hydraulic rod 24 is fixedly connected with an elastic plate 22. The top end and the bottom end of the elastic plate 22 abut against the upper and lower partition plates 10, respectively. The side of the elastic plate 22 away from the adjusting rod 21 abuts against the outer wall of the elastic piece 6.

[0081] The inner wall of the receiving chamber 7 is fixedly installed with two transversely arranged mounting plates 8. The hydraulic rod 24 is located between the two mounting plates 8. The fixed end of the hydraulic rod 24 is fixedly connected with the inner wall of the receiving chamber 7, and the outer wall abuts against the outer wall of the receiving chamber 7.

[0082] The hydraulic rod 24 is fixed in the receiving chamber 7 and is used to drive the adjusting rod 21 to move, realizing the moving effect of the two adjusting rods 21. The upper and lower ends of the elastic plate 22 abut against the two partition plates 10, which can ensure that the elastic piece 6 does not overflow in the direction of the hydraulic rod 24 when the adjusting rod 21 pushes the bent part of the elastic piece 6, so that the elastic piece 6 can only move to the opening of the fork 3.

[0083] Two mounting plates 8 further support the hydraulic rod 24, making the hydraulic rod 24 more stable and secure, and the system of the automatic stereoscopic storage rack body 1 itself can control the opening and closing of the hydraulic rod 24. The automatic stereoscopic storage rack body 1 sends signals to the control unit of the hydraulic system, which is like a "brain". It can interpret these signals and convert them into operation instructions for hydraulic pumps, hydraulic valves and other components.

[0084] Referring to Figure 4 and Figure 5 , the end of the sliding port 9 away from the storage chamber 7 extends obliquely towards the opening of the fork 3, until it communicates with the outside of the fork 3.

[0085] After the bulging elastic member 6 is pressed by the weight on the movable plate 5, part of the area of the elastic member 6 will accumulate at the position of the sliding port 9, and the opening of the sliding port 9 is close to the outer wall of the elastic member 6. When the elastic member 6 bulges near the sliding port 9, the outer wall of the bulging part of the elastic member 6 will be stuck in the opening of the sliding port 9. As to why the sliding port 9 is obliquely arranged, it is to ensure that when the elastic member 6 extends out through the sliding port 9, the elastic member 6 itself will not have an excessively large angle of bending, which can increase the service life of the elastic member 6, and the elastic member 6 itself will not have a more serious bend, further ensuring the elastic recovery function of the elastic member 6.

[0086] Referring to Figure 10 , the fork 3 is provided with two accommodating grooves 26, which are vertically corresponding. The two accommodating grooves 26 correspond to the sides of the two movable plates 5 away from the notch 20 respectively. The outer wall of the movable plate 5 is hinged with a spring hinge 27 between the inner bottom wall of the accommodating groove 26. 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 after the movable plate 5 is flattened. The movable plate 5 is hinged with the fork 3 through the spring hinge 27. The spring hinge 27 can continuously exert a force on the movable plate 5 to make the movable plate 5 close to the partition plate 10, so that the movable plate 5 can be inclined in the initial state and be in an inclined state together with the fork 3, facilitating insertion into the fork hole 4.

[0088] Referring to Figure 9 , the servo motor 31 is fixedly installed on the inner bottom wall of the placing groove 30. The driving end of the servo motor 31 is fixedly connected with the end of the rotating rod 18 extending into the inside of the placing groove 30. One side of the fork 3 is provided with an embedded groove 25 extending along the axial direction of the fork 3. One end of the embedded groove 25 is close to the placing groove 30 and communicates with the two placing grooves 30.

[0089] The embedded slot 25 is a channel for placing the power supply line of the servo motor 31, and the power supply line can pass through the embedded slot 25 to the stacker, and the power supply line is convenient for driving the controllable servo motor 31. As for the power supply channel of the hydraulic rod 24, the hydraulic rod 24 is already in the inside of the fork 3, and the fork 3 is directly connected with the stacker, so that the hydraulic rod 24 in the fork 3 can be directly powered.
