Description

Technical Field

[0001] The present invention relates to the technical field of stackers, in particular to a stacker for I-spools. Background Art

[0002] A stacker is a lifting device that combines the structural features of a crane and a forklift. Like a crane, it has a bridge and a slewing trolley. The bridge operates above the warehouse, and the slewing trolley rides on top of the bridge. At the same time, a bridge stacker has the structural features of a forklift, with a fixed or retractable column mounted with a fork or other lifting device.

[0003] For example, a stacker with publication number CN219620035U includes a lifting mechanism and a loading mechanism comprising a frame and two loading platforms disposed within the frame. The two loading platforms are arranged vertically. The frame is connected to the lifting mechanism, and the loading mechanism is configured to move vertically relative to the lifting mechanism. This approach improves the stacker's integration, reduces its size and weight, saves costs, and improves stacking efficiency.

[0004] Traditional stackers rely solely on two telescopic forks to pick up, place, and stack goods. However, stackers need to move back and forth within the aisles of a high-bay warehouse, and the moving goods are not fixed in place. If they collide with other goods, they can easily tilt or fall. This is especially true when picking up and placing goods with special-shaped structures such as I-spools, where the center of gravity cannot be determined. Once the goods tip over or fall, significant losses will result.

[0005] Therefore, we propose a spool stacker to solve the above-mentioned problems. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Under the action of the base guide rail, support mechanism, lifting mechanism and extension mechanism, the I-shaped wheel body can move along the X-axis, Y-axis and Z-axis in the aisle of the three-dimensional warehouse, which is convenient for picking up, placing and transferring the I-shaped wheel body. The four sets of extension rods rotate in the internal space of the fork. When the four sets of extension rods are fully deployed to the periphery and are all located at the lower end of the I-shaped wheel body, the range of contact between the fork and the I-shaped wheel body becomes larger. The extension rods are deployed from the center point of the fork, and its outer periphery forms a circular center structure, which adapts to the shape of the bottom of the I-shaped wheel body. Even if the center of gravity of the I-shaped wheel body is offset or tilted to one side, it has good supporting force. The I-shaped wheel body is not easy to fall after a collision, and the protective effect is greatly enhanced.

[0021] 2. When the fork moves to the lower end of the spool body, the edge of the bottom of the spool body just overlaps the height of the tilting block. During this process, multiple extension rods can be automatically driven to unfold and be located at the lower end of the spool body. No additional operation is required to protect the spool body. After the tilting blocks move, both are located on both sides of the spool body, which is convenient for determining the center of circle and center of gravity of the spool body and has a certain positioning effect. The extension rods are always located at the lower end of the spool body until the spool body is lowered. Therefore, the protection time is longer and the protection effect is better.

[0022] 3. When the fork removes the spool body, the first elastic member loses its restraint, and the tilting block, the first connecting rod, the second connecting rod, the third connecting rod and the extension rod can be reset, so that the extension rod can be returned to the internal space of the fork, making it easier to pick up and move the spool body for the second time.

[0023] 4. When the tilting block moves, the trapezoidal groove and tilting groove on one side of the pulling block and the hemispherical block, stabilizing block and suction cup at the corresponding position are lifted upward to compensate for the height difference between the extension rod and the fork. When the pulling block moves to the side wall of the second side groove, the tilting block continues to move without affecting the deployment of the extension rod. After the tilting block moves, multiple suction cups form a cocircle with the center of the circle consistent with the center of the I-wheel, providing multi-point support for the I-wheel body, further increasing the stability of the I-wheel body.

[0024] 5. If the spool body needs to be moved to a higher place, the lifting platform needs to be lifted upwards. At this time, the second pulling rope has a certain pulling force downwards, the piston can move, and the suction cup generates suction, which can tightly suck the bottom of the spool body. The spool body is moved to a higher place. On the premise of increasing the strength with the spool body, it has a better fixing effect and can better ensure the stability of the spool body.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-6 A stacker for I-wheels includes a base guide rail 1 and a supporting mechanism 2 installed on the base guide rail 1. A lifting mechanism 3 is provided at the upper end of the supporting mechanism 2, and an extending mechanism 4 is provided on the lifting mechanism 3. The upper end of the extending mechanism 4 is provided with an I-wheel body 9. The base guide rail 1 is fixedly installed in the lane of the three-dimensional warehouse. The lower end of the supporting mechanism 2 moves along the base guide rail 1, so that the I-wheel body 9 can move along the X-axis in the lane of the three-dimensional warehouse. The lifting mechanism 3 can move up and down along the supporting mechanism 2 to make the I-wheel body 9 move along the Y-axis in the three-dimensional warehouse. At the same time, the extending mechanism 4 moves along the lifting mechanism 3, and the I-wheel body 9 can move along the Z-axis in the three-dimensional warehouse, ensuring the multi-directional movement of the I-wheel body 9 and facilitating the picking, placement and transfer of the I-wheel body 9.

[0037] The lifting mechanism 3 includes a lifting cargo platform 31 and vertical sliding members 32 fixedly installed on both sides of the lifting cargo platform 31. The extending mechanism 4 includes a fork 41 slidably installed on the upper end of the second slide rail 36. The lifting cargo platform 31 is slidably connected to the supporting mechanism 2 through the vertical slide member 32. The lifting cargo platform 31 is used to carry the extending mechanism 4 and the I-wheel body 9 and has a certain bearing capacity. The upper end of the lifting cargo platform 31 is fixedly installed with a first slide rail 35, and the upper end of the first slide rail 35 is slidably installed with a second slide rail 36. Under the action of the first slide rail 35 and the second slide rail 36, the fork 41 of the extending mechanism 4 can be extended along the Z axis to a longer range, which is used to directly extend to the lower end of the I-wheel body 9, so as to facilitate the picking and placing of the I-wheel body 9.

[0038] A first side groove 411 is provided on both sides of the fork 41, and four groups of extension mechanisms 5 are provided inside the fork 41. The extension mechanism 5 includes an extension rod 51 rotatably installed at one end inside the fork 41. The extension rod 51 is also inserted and connected with the first side groove 411. A through hole 52 is provided at the upper end of the extension rod 51. The four groups of extension rods 51 rotate in the internal space of the fork 41 until the four groups of extension rods 51 are fully extended to the periphery. The four extension rods 51 are all located at the lower end of the I-wheel body 9, which increases the contact area between the device and the I-wheel body 9, greatly ensures the stability of the I-wheel body 9, and is not easy to fall.

[0039] When the four extension rods 51 are fully extended, the range in which the forks 41 contact the spool body 9 becomes larger. The extension rods 51 are extended from the center point of the forks 41, and their outer periphery forms a circular center structure, which adapts to the shape of the bottom of the spool body 9. Even if the center of gravity of the spool body 9 is offset or tilted to one side, it has good supporting force. The spool body 9 is not easy to fall after a collision, and the protective effect is greatly enhanced.

[0040] Example 2: Please refer to Figure 1-Figure 3 The support mechanism 2 includes two column guide rails 21 slidably mounted on the base guide rail 1, wherein a ladder 22 is fixedly mounted on the side wall of one of the column guide rails 21, and the ladder 22 is for the operator to crawl, and a hoist 23 is provided on the side wall of the other column guide rail 21, and a traction rope 24 is connected to the hoist 23. The upper ends of the two column guide rails 21 are jointly mounted with a top frame 25, and a guide wheel 26 is rotatably mounted on the side wall of the top frame 25. The traction rope 24 is rotatably mounted on the guide wheel 26, and the end of the traction rope 24 away from the hoist 23 is also fixedly connected to the lifting cargo platform 31. The hoist 23 includes a drum for winding the traction rope 24, a lifting motor and a rope stopper. After the lifting motor is turned on, it drives the traction rope 24 to wind or loosen on the drum, which is used to drive the lifting cargo platform 31 and the fork 41 to move in the Y-axis direction.

[0041] A detection sensor 33 is fixedly installed at the front end of the lifting cargo platform 31. The detection sensor 33 adopts an isym photoelectric reflection sensor, which is used to detect whether there is cargo or obstacles in front of the lifting cargo platform 31.

[0042] Example 3: Please refer to Figure 2-Figure 8 A first slide groove 412 is provided at the upper end of the fork 41, and a second slide groove 413 is provided on the bottom wall of the fork 41. The interior of the fork 41 is a hollow structure, and the first side groove 411, the first slide groove 412, and the second slide groove 413 are all interconnected. The internal space is used to accommodate the extension rod 51 to ensure that the extension rod 51 has space to rotate.

[0043] The extending mechanism 4 is internally provided with an extrusion mechanism 6, which includes an inclined block 61 slidably mounted on the upper end of the first slide groove 412, and the inclined block 61 has a large inclination. A first connecting rod 62 is fixedly mounted on one end of the inclined block 61, and a second connecting rod 63 is fixedly mounted on one end of the first connecting rod 62. Both ends of the second connecting rod 63 are rotatably mounted with a third connecting rod 64, and the third connecting rod 64 is interlaced and connected with the first side groove 411, and the third connecting rod 64 is also rotatably connected to the side wall of the extension rod 51 at the corresponding position.

[0044] In the initial state, the tilting block 61 is higher than the fork 41. When the fork 41 moves to the lower end of the I-wheel body 9, the edge of the bottom of the I-wheel body 9 just overlaps the high point of the tilting block 61. As the I-wheel body 9 is pressed down by its own weight, the tilting block 61, the first connecting rod 62, and the second connecting rod 63 move toward both sides of the fork 41. When the second connecting rod 63 moves outward, the third connecting rod 64 rotates, and its outer periphery expands outward, driving the outer extension rods 51 to expand, which can automatically drive the four extension rods 51 to rotate and be located at the lower end of the I-wheel body 9, with continuity.

[0045] The lower end of the tilting block 61 is rotatably mounted with a moving wheel 65, which slides in the second slide groove 413. The second slide groove 413 is located on the longitudinal horizontal line of the fork 41 to ensure that the moving trajectory of the tilting block 61 is a straight line. The two third connecting rods 64 are deployed at the same angle and time, that is, the four extension rods 51 rotate and deploy in unison, which is convenient for protecting the I-wheel body 9. The end of the tilting block 61 away from the first connecting rod 62 is fixedly mounted with a telescopic rod 66, and the end of the telescopic rod 66 away from the tilting block 61 is also fixedly connected to the inner wall of the fork 41. Next, a first elastic member 67 is installed between the tilting block 61 and the inner wall of the fork 41. When the tilting block 61 and the first connecting rod 62 move outward, the first elastic member 67 and the telescopic rod 66 are squeezed. When the fork 41 removes the I-shaped wheel body 9, the first elastic member 67 loses its restraint, and the tilting block 61, the first connecting rod 62, the second connecting rod 63, the third connecting rod 64 and the extension rod 51 can be reset, so that the extension rod 51 can be returned to the internal space of the fork 41, which is convenient for the second picking up and moving of the I-shaped wheel body 9.

[0046] After the tilting blocks 61 move, both are located on both sides of the I-wheel body 9, which is convenient for determining the center of the circle and the center of gravity of the I-wheel body 9, has a certain positioning effect, and ensures the stability of the I-wheel body 9. When the I-wheel body 9 is moved, the extension rod 51 is always located at the lower end of the I-wheel body 9 until the I-wheel body 9 is lowered, so the protection time is long and the protection effect is good.

[0047] Example 4: Please refer to Figure 3-Figure 8 A second side groove 53 is provided on the side wall of the extension rod 51, and a connecting mechanism 8 is provided inside the extension mechanism 5. The connecting mechanism 8 includes a pulling block 81 rotatably connected to the third connecting rod 64. The pulling block 81 is inserted into the second side groove 53 and is slidably installed inside the extension rod 51 for sliding connection.

[0048] A trapezoidal groove 82 is provided on the pulling block 81 , one end of which is adapted to the hemispherical block 72 , an inclined groove 83 is provided on one end of the pulling block 81 , and an avoidance hole 84 is provided on the pulling block 81 , which is interlaced with the sleeve 75 .

[0049] A sliding and stabilizing mechanism 7 is provided at the upper end of the extension mechanism 5. The sliding and stabilizing mechanism 7 includes a sliding and stabilizing block 71 arranged at the upper end of the extension rod 51. The sliding and stabilizing block 71 is arranged in the through hole 52. A hemispherical block 72 is fixedly installed at the lower end of the sliding and stabilizing block 71. A suction cup 73 is fixedly installed at the upper end of the sliding and stabilizing block 71. A second elastic member 74 is jointly installed between the suction cup 73 and the extension rod 51.

[0050] When the tilting block 61 moves, it will drive the pulling block 81 to move along the second side groove 53. The length of the second side groove 53 is shorter, and the pulling block 81 moves a shorter distance. The trapezoidal groove 82 and the tilting groove 83 on one side of the pulling block 81 and the hemispherical block 72 at the corresponding position are lifted up until the sliding block 71 and the suction cup 73 are lifted up to compensate for the height difference between the extension rod 51 and the fork 41. When the pulling block 81 is displaced to the side wall of the second side groove 53, the tilting block 61 continues to move without affecting the deployment of the extension rod 51. When the tilting block 61 moves to the point where it can no longer move, the sliding block 71 and the suction cup 73 have been completely lifted, thereby providing circumferential support to the I-wheel body 9.

[0051] After the tilting block 61 moves, the plurality of suction cups 73 form a common circle, the center of which is consistent with the center of the spool, providing multi-point support for the spool body 9 and further increasing the stability of the spool body 9.

[0052] Example 5: Please refer to Figure 3-Figure 9 A rotating rod 414 is installed vertically inside the fork 41, and the rotating rod 414 is set on both sides of the fork 41 near the center. A connecting rod 34 is fixedly installed on one end of the lifting cargo platform 31 away from the detection sensor 33.

[0053] A sleeve 75 is provided at one end of the hemispherical block 72, and a channel 76 is commonly connected between the sliding block 71, the suction cup 73, and the sleeve 75. A first pull rope 77 is provided inside the channel 76, and a piston 78 is fixedly installed at one end of the first pull rope 77. The piston 78 is slidably installed inside the sleeve 75. A second pull rope 79 is commonly installed between two adjacent first pull ropes 77. The second pull rope 79 is rotatably installed on the rotating rod 414. The end of the second pull rope 79 away from the first pull rope 77 is overlapped on the overlap rod 34 and fixedly connected to the base guide rail 1.

[0054] If the I-wheel body 9 needs to be moved to a higher position, the lifting cargo platform 31 needs to be lifted upward. At this time, the second pulling rope 79 has a certain pulling force downward, and the first pulling rope 77 simultaneously applies force toward the rotating rod 414, driving the piston 78 to move toward the rotating rod 414. Since the lower end of the I-wheel body 9 has been in contact with the suction cup 73 at this time, the channel 76 and the sleeve 75 inside the suction cup 73 are connected. When the piston 78 moves, the suction cup 73 generates suction until the I-wheel body 9, the channel 76, the sleeve 75 and the piston 78 form a closed space, so that the suction cup 73 can tightly suck the bottom of the I-wheel body 9. The I-wheel body 9 is moved to a higher position. On the premise of increasing the connection with the I-wheel body 9, it has a better fixing effect and can better ensure the stability of the I-wheel body 9.
