Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of stereoscopic warehouse equipment, and in particular to stacking equipment for intelligent stereoscopic warehouses. Background Art
[0002] Stacking equipment for intelligent high-bay warehouses is a core automation component of modern logistics and warehousing systems, primarily used for storing, retrieving, and transporting goods between high-bay shelves. Through precise control systems and mechanical transmission mechanisms, it achieves efficient movement of goods within a three-dimensional space. Its advantages include high automation, rapid operation, and efficient space utilization, significantly improving the operational efficiency of warehousing and logistics. It is widely used in numerous industries, including manufacturing, e-commerce, and pharmaceuticals. The forklift, a key component for directly carrying and transporting goods, has a crucial role in determining the safety and stability of cargo transportation. In traditional intelligent high-bay warehouse stacking equipment, when transporting goods, the fork frame often causes the goods to become unstable. On the one hand, the goods stored in the high-bay warehouse are generally box-type packaged goods, which are stored on pallets in a stacked manner and then shipped to the fork frame through a transport device. In the process of the stacker driving such goods into the high-bay warehouse storage rack through the fork frame, starting and stopping will inevitably cause the fork frame to pause momentarily. At this time, the goods are prone to shaking and offset due to factors such as inertia and vibration. On the other hand, the existing fork frame has a relatively simple way to restrain the goods. The most common one is the external frame type limit protection. The size of this type of external frame is generally single. In order to meet the transportation and storage needs of goods of different sizes, the corresponding design size of its external frame is large, and there is a large gap between it and the goods. It is not in direct contact with the goods, resulting in a low overall positioning protection effect for the goods.
[0003] Therefore, it is necessary to provide a stacking device for an intelligent stereoscopic warehouse to solve the above technical problems. Summary of the Invention

The cross-section of the C-shaped rod is rectangular. A sleeve is sleeved on the outside of the C-shaped rod. A rectangular top plate is fixedly installed on the top of the sleeve. A V-shaped groove is provided on the inner side wall of the rectangular top plate, and part of the path of the V-shaped groove is parallel to the side wall of the rectangular top plate. An extrusion rod is horizontally inserted in the V-shaped groove, and one end of the extrusion rod is fixedly connected to the L-shaped plate.

[0013] Compared with related technologies, the stacking equipment for intelligent high-bay warehouses provided by the present invention has the following beneficial effects: The present invention provides a stacking device for an intelligent three-dimensional warehouse. When the goods enter the fork frame through a conveying device, the hydraulic push rod can be started, and the hydraulic push rod drives the external plate, small-diameter tube, large-diameter tube and horizontal plate to descend horizontally, so that the horizontal height of the support rod and the rectangular tube follows and descends. After descending to a certain height, the rectangular tube located in the top area of the goods will be close to the top of the goods under the action of its own gravity. When it continues to descend, the rectangular tubes at other positions in the top area of the goods continue to descend. There is no relative movement between the rectangular tube at this position and the support rod, and the inner wall of the rectangular tube at some positions supports the outer side of the goods to position and lock it in the horizontal direction. At this time, when the stacker is started again to transport the goods, the goods on the fork frame are not easy to shake, thereby ensuring the stability of the goods when placed in the three-dimensional warehouse. In addition, this method can meet the positioning, locking and protection requirements of goods of different sizes, and is more practical.
[0014] The present invention provides a stacking device for an intelligent three-dimensional warehouse. An internal threaded connector is welded to the inner wall of a rectangular tube near an opening at the bottom thereof. A contact head is installed inside the internal threaded connector through threaded engagement. The contact head has various shapes and matches the outer surface shape of goods stored in batches in the three-dimensional warehouse. The smaller the size of the rectangular tube, the smaller the size of the contact head. The smaller the spherical contact head, the more contact points with the goods. The multiple contact heads can contact multiple points on the surface of special-shaped goods and position the special-shaped goods in the horizontal direction.
[0015] The present invention provides a stacking device for an intelligent stereoscopic warehouse. The present invention is provided with an extension part. The first swing arm and the second swing arm of the extension part can be stretched out, so that the first quadrilateral auxiliary tube and the second quadrilateral auxiliary tube are separated from the initial end face contact state, thereby realizing multi-point support for the rectangular tube at the outer position, thereby further improving the stability of the goods during transportation. The number of the extension parts is multiple, which further increases the contact points with the rectangular tube, and further improves the support strength of the rectangular tube. At the same time, the first quadrilateral auxiliary tube and the second quadrilateral auxiliary tube in some of the extension parts will be directly moved to the outside of the goods. At this time, the first quadrilateral auxiliary tube and the second quadrilateral auxiliary tube at this position will be erected on the outside of the goods as auxiliary support parts, thereby realizing indirect limitation of the goods, effectively preventing the goods from falling from high altitude, and further improving safety.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, these terms are defined based on the entire content of this specification.
[0019] See also Figures 1-9 The stacking equipment for an intelligent stereoscopic warehouse described in the present invention includes a fork frame 1. The fork frame 1 is one of the components of the stacker in the intelligent stereoscopic warehouse. That is, the fork frame 1 can be mounted on the stacker in the existing intelligent stereoscopic warehouse on the market. The specific installation process is the existing technology and will not be described in detail in this embodiment. An L-shaped plate 2 is fixedly installed on the top of the fork frame 1, and a hydraulic push rod 3 is installed at the center of the top of the horizontal plane of the L-shaped plate 2. An external plate 4 is fixedly connected to the end of the piston rod of the hydraulic push rod 3. It can be understood that the piston rod of the hydraulic push rod 3 passes through the external plate 4 in the vertical direction, and a reserved hole is provided on the external plate 4 for the piston rod to move in the vertical direction; A small-diameter tube 41 is symmetrically welded to the lower end surface of the external plate 4, a large-diameter tube 42 is concentrically welded to the bottom of the small-diameter tube 41, and a horizontal plate 5 is fixedly installed to the bottom of the large-diameter tube 42. The small-diameter tube 41 and the large-diameter tube 42 are made of the same material and can be either hollow or solid. A support rod 51 is fixedly installed at the bottom of the horizontal plate 5. A plurality of support rods 51 are arranged in a U-shaped matrix with the center line of the piston rod as the axis, and there is a mounting gap between adjacent support rods 51 in the horizontal direction; A threaded rod 53 is welded to the center of the bottom end face of any support rod 51. The diameter of the threaded rod 53 is smaller than that of the support rod 51. A washer 54 and a locking bolt 55 are installed on the outside of the threaded rod 53 from top to bottom. The locking bolt 55 can be installed on the threaded rod 53 through threaded engagement. The washer 54 is located between the lower end face of the support rod 51 and the upper end face of the locking bolt 55, and is positioned and locked by the locking bolt 55. A guide rod 56 is symmetrically mounted on the upper end surface of the gasket 54. A limit plate 57 is sleeved on the outer wall of the two guide rods 56 on the same position of the gasket 54. The limit plates 57 can slide vertically along the guide rods 56, but the two guide rods 56 lock the limit plates 57 from circumferential deflection. A rectangular tube 6 is welded to the outside of the limiting piece 57, and the movement of the rectangular tube 6 is consistent with that of the limiting piece 57; The number of rectangular tubes 6 is the same as the number of support rods 51. The outer walls of any two adjacent rectangular tubes 6 are in contact but not connected. The bottom end surfaces of any rectangular tubes 6 have the same horizontal height. It can be understood that the bottom end surfaces of the rectangular tubes 6 at any position have the same horizontal height in the initial state. The multiple rectangular tubes 6 are arranged in the same manner as the support rods 51, and are all distributed in a U-shaped matrix. The square area formed by the outer side walls of the multiple rectangular tubes 6 located at the outermost position is larger than the top view area of the goods in the warehouse. It can also be understood that the lower end surfaces of the multiple rectangular tubes 6 can completely cover the top surface of all the stacked goods on the fork frame 1; The width of the rectangular tube 6 is 1-5 cm. This embodiment is described by taking the rectangular tube 6 with a width of 5 cm as an example. Figure 1 As shown, if the cargo is conventional cargo (non-special-shaped box cargo), when the cargo enters the fork frame 1 through the conveying device, the hydraulic push rod 3 can be activated, and the hydraulic push rod 3 drives the external plate 4, the small-diameter tube 41, the large-diameter tube 42 and the horizontal plate 5 to descend horizontally, and the horizontal height of the support rod 51 and the rectangular tube 6 will follow and descend. After descending to a certain height, the rectangular tube 6 located in the top area of the cargo will be close to the top of the cargo under the action of its own gravity. When it continues to descend, the rectangular tube 6 in the above-mentioned area moves upward relative to the support rod 51, that is, the limit plate 57 moves vertically upward relative to the guide rod 56; like Figure 1 As shown, the rectangular tubes 6 at other positions in the cargo top area continue to descend, and the rectangular tubes 6 at this position do not move relative to the support rods 51, and the inner walls of the rectangular tubes 6 at some positions support the outer side of the cargo to position and lock it in the horizontal direction. At this time, when the stacker is started to transport the cargo, the cargo on the fork frame 1 is not easy to shake, ensuring the stability of the cargo when it is placed in the three-dimensional warehouse. In addition, this method can meet the positioning and locking protection requirements of cargo of different sizes and is more practical. After the fork frame 1 drives the goods to the designated position, the hydraulic push rod 3 drives the piston rod back to the initial position, and simultaneously drives the rectangular tube 6 at any position to separate from the surface of the goods. At this time, the goods on the fork frame 1 can be unloaded to the three-dimensional warehouse rack; In response to the positioning requirements of goods of different sizes, the number of rectangular tubes 6 that move relative to the support rod 51 is changed. At the same time, when the goods enter the fork frame 1 through the conveying device, the placement position of the goods relative to the fork frame 1 is fixed and unique; On the same fork frame 1 , the size of the rectangular tube 6 is not fixed uniquely, but the size of the rectangular tube 6 in the same U-shaped path needs to be kept consistent.
[0020] The outer wall surfaces of the rectangular tubes 6 are all smooth surfaces, which reduces the wear between the adjacent rectangular tubes 6 when they slide; At the same time, the contact surfaces of any two adjacent rectangular tubes 6 are coated with lubricating grease to further reduce the friction and loss between the contact surfaces of adjacent rectangular tubes 6; The rectangular tube 6 at any position can be removed by removing the locking bolt 55. If the rectangular tube 6 at any position is deformed or damaged, it can be quickly disassembled and replaced. The upper end face of the gasket 54 is embedded with a silicone pad, and the lower end face of the limiting piece 57 is in contact with the silicone pad but not connected. When the rectangular tube 6 returns to its initial position, the lower end face of the limiting piece 57 will directly contact the silicone pad, reducing the impact force on the gasket 54 and avoiding deformation of the gasket 54.
[0021] In another embodiment, see Figures 1-9 The bottom of the rectangular tube 6 is welded with an internal thread connector 61 on the inner wall near the opening position. The internal thread connector 61 is installed with a contact head 62 through threaded fitting. The contact head 62 is equipped with various shapes and matches the outer surface shape of the goods stored in batches in the stereoscopic warehouse. In this embodiment, the contact head 62 is spherical in shape and smaller than the rectangular tube 6. Similarly, the smaller the rectangular tube 6, the smaller the size of the contact head 62. The smaller the spherical contact head 62, the more contact points with the cargo. The multiple contact heads 62 can contact multiple points on the surface of the irregularly shaped cargo and locate the horizontal position of the irregularly shaped cargo.
[0022] In another embodiment, see Figures 1-9 The upper end surface of the large diameter tube 42 is fixedly mounted with a C-shaped plate 52, and both ends of the C-shaped plate 52 are welded with a quadrilateral main pipe 7, which is a metal component, and the inner side surface of the quadrilateral main pipe 7 is a smooth surface; The inner and outer planes of the quadrilateral main pipe 7 are in contact with the outer walls of the inner and outer rectangular pipes 6 respectively. The outer walls of the outermost rectangular pipes 6 are laterally limited by the inner walls of the quadrilateral main pipe 7. When the rectangular pipe 6 is positioned and locked for the goods, if it is subjected to a lateral impact force, the inner wall of the quadrilateral main pipe 7 can offset the impact force, and the inner wall of the quadrilateral main pipe 7 locks the lateral position of the rectangular pipe 6, effectively preventing the rectangular pipe 6 from deformation. Furthermore, the rectangular tubes 6 at the outermost positions are all made of metal, and any rectangular tubes 6 at other positions are made of hard plastic. The U-shaped area formed by the combination of the metal rectangular tubes 6 is larger than the width of the maximum cargo stored in the three-dimensional warehouse, that is, the rectangular tubes 6 made of hard plastic will contact the top of the cargo. The lighter weight reduces the pressure on the top of the cargo, while reducing the manufacturing cost of the rectangular tubes 6, and the practicality is further improved.
[0023] In another embodiment, see Figures 1-9The bottom of the quadrilateral main pipe 7 is provided with an extension portion 8, which includes a first quadrilateral auxiliary pipe 81 and a second quadrilateral auxiliary pipe 82 arranged in sequence along the vertical direction. The upper end surface of the first quadrilateral auxiliary pipe 81 is fixedly connected to the lower end surface of the quadrilateral main pipe 7. The first quadrilateral auxiliary pipe 81 and the second quadrilateral auxiliary pipe 82 are of the same shape, size and material; The first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82 are symmetrically provided with rectangular holes 83. A shaft hole 84 and a strip hole 85 are symmetrically provided on both sides of the rectangular hole 83. A rotating shaft 86 is installed in each of the shaft hole 84 and the strip hole 85. A first swing arm 87 and a second swing arm 88 are installed in a cross shape between the two rectangular holes 83 in the first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82. The cross shape can be referred to Figure 6 The shape is shown in the enlarged figure; The first swing arm 87 and the second swing arm 88 are rotatably connected to the rotating shaft 86 at both ends. A pin 89 is installed at the center of the cross between the first swing arm 87 and the second swing arm 88. That is, the first swing arm 87 and the second swing arm 88 can deflect relative to each other with the pin 89 as the rotation center. In the initial position, that is, when the end faces of the first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82 are in contact, there is a natural angle between the first swing arm 87 and the second swing arm 88. A C-shaped rod 71 is fixedly mounted on the top of the quadrilateral main pipe 7. A sleeve 72 is sleeved on the outside of the C-shaped rod 71. The sleeve 72 can slide along the outer wall of the C-shaped rod 71. Since the cross section of the C-shaped rod 71 is rectangular, the sleeve 72 cannot rotate on the outer wall of the C-shaped rod 71. A rectangular top plate 73 is fixedly mounted on the top of the sleeve 72. A V-shaped groove 74 is formed on the inner side wall of the rectangular top plate 73. Part of the path of the V-shaped groove 74 is parallel to the side wall of the rectangular top plate 73. It can be understood that part of the path of the V-shaped groove 74 is perpendicular to the horizontal plane (such as Figure 5 The remaining path of the V-groove 74 is inclined to the horizontal plane (eg, Figure 5 N segments identified in ); It should be noted that under normal conditions, the maximum horizontal drop distance of the horizontal plate 5 should be less than the horizontal height difference between the two ends of the N segment of the V-shaped groove 74. Similarly, the N segment of the V-shaped groove 74 can be connected to the end of the M segment. An extrusion rod 75 is horizontally inserted into the V-shaped groove 74, and one end of the extrusion rod 75 is fixedly connected to the L-shaped plate 2. The C-shaped rod 71, the sleeve 72 and the rectangular top plate 73 change their positions synchronously with the movement of the hydraulic push rod 3, that is, the horizontal height can be changed, while the extrusion rod 75 does not change its position with the movement of the hydraulic push rod 3. The outer wall of the rectangular top plate 73 is fixedly connected to a side rod 76, and the end of the side rod 76 is provided with a U-shaped hole 77. An extension rod 78 is provided in the U-shaped hole 77, and the end of the extension rod 78 is concentrically fixed to the end surface of the rotating shaft 86 of the strip hole 85. When working, when the hydraulic push rod 3 is started to position the position of the goods through the rectangular tube 6, the horizontal height of the rectangular top plate 73 is synchronously lowered, and the V-shaped groove 74 will slide along the outer wall of the extrusion rod 75. When it is Figure 5 When the M section in the middle slides to the N section, the extrusion rod 75 will apply a lateral extrusion force to the V-shaped groove 74, so that the rectangular top plate 73 pushes the sleeve 72 to slide on the C-shaped rod 71. After the rectangular top plate 73 moves horizontally, it simultaneously drives the side rod 76 to move. The U-shaped hole 77 provided at the bottom of the side rod 76 drives the extension rod 78 to move along the path direction of the strip hole 85, that is, drives the rotating shaft 86 at this position to move along the strip hole 85. During the movement of the rotating shaft 86, an extrusion force is applied to the second swing arm 88, so that the first swing arm 87 and the second swing arm 88 rotate relative to the pin 89, and the second quadrilateral auxiliary tube 82 is spread apart by the first swing arm 87 and the second swing arm 88. At this time, the first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82 are separated from the initial end face contact state, thereby realizing multi-point support for the rectangular tube 6 at the outer position, thereby further improving the stability during cargo transportation; Furthermore, the number of the extension parts 8 is multiple, and the multiple extension parts 8 are placed flush in the vertical direction. When the multiple extension parts 8 are arranged, from bottom to top, the first swing arm 87 in the extension part 8 is connected to the second swing arm 88. At this time, the number of the first quadrilateral auxiliary tubes 81 and the second quadrilateral auxiliary tubes 82 increases. The first quadrilateral auxiliary tubes 81 and the second quadrilateral auxiliary tubes 82 in some extension parts 8 are used to further increase the contact points with the rectangular tube 6, thereby further improving the support strength of the rectangular tube 6, while the other part of the extension parts The first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82 in 8 will be directly displaced to the outside of the cargo (not in contact with the cargo, and in the cargo area below the horizontal height of the lower end surface of the rectangular tube 6). At this time, the first quadrilateral auxiliary tube 81 and the second quadrilateral auxiliary tube 82 at this position will be installed on the outside of the cargo as auxiliary supporting parts to achieve indirect position limiting of the cargo. That is, when the fork frame 1 has an unexpected collision (such as a collision with a storage rack in a three-dimensional warehouse due to a program error), it can effectively prevent the cargo from falling from a high altitude, thereby further improving safety.
