Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics equipment technology, and in particular to an automated warehouse rack that facilitates the storage and retrieval of goods. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are fundamental equipment used in warehousing and logistics systems for storing goods. By extending vertical space, they can significantly increase storage capacity within a limited floor area. Currently, traditional AS / RS racks typically consist of uprights and multiple layers of storage shelves fixed to the uprights, with boxes of materials placed layer by layer on the shelves. However, these existing AS / RS racks still have the following shortcomings in practical use: First, the shelf spacing of most shelves is fixed and cannot be flexibly adjusted according to the height of the boxes stored. When storing boxes of different sizes, the height of boxes from different batches may vary. Shelves with fixed spacing either waste upper space or cannot accommodate taller boxes, reducing the space utilization rate of the shelves.

[0003] Secondly, accessing goods in the upper levels of existing automated warehouse racking systems is extremely inconvenient. For boxes placed at higher levels, operators need to use ladders or other tools to reach them, which is not only cumbersome and inefficient but also poses a high safety risk. Although some automated warehouses use stacker cranes and other equipment for goods storage and retrieval, these devices are expensive and structurally complex. Utility Model Content

[0004] The main purpose of this utility model is to provide a three-dimensional warehouse rack that facilitates the storage and retrieval of goods. It can effectively solve the problems of low space utilization caused by the fixed spacing of the shelves in existing three-dimensional warehouse racks, which cannot adapt to goods of different heights, as well as the inconvenience of storing and retrieving goods at high heights, the safety hazards and low efficiency of operators having to climb ladders to work.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automated storage and retrieval system (AS / RS) racking system for easy storage and retrieval of goods includes uprights and multi-layer placement panels mounted on the uprights. It also includes a spacing adjustment mechanism, a lifting mechanism, and a pick-and-place mechanism. The placement panels are slidably connected to the uprights via the spacing adjustment mechanism. The lifting mechanism is located at the top of the uprights and drives the pick-and-place mechanism to move up and down. The pick-and-place mechanism is movably positioned at the front of the uprights. Guide rails are provided on the placement panels, and a positioning component is located at one end of each panel. The spacing adjustment mechanism allows for changing the installation height of the placement panels on the uprights, accommodating goods boxes of different heights and improving space utilization. The lifting mechanism, in conjunction with the pick-and-place mechanism, can lower high-rise goods to lower locations for easy and safe operation. The guide rails and positioning component help ensure alignment and limit movement during storage and retrieval, reducing the risk of offset or tilting.

[0006] As a further preferred embodiment of this utility model, the column is provided with a plurality of adjustment holes spaced apart along the height direction. The spacing adjustment mechanism includes a sliding sleeve slidably fitted onto the column, and the placement plate is fixedly connected to the side wall of the sliding sleeve. The sliding sleeve has positioning holes corresponding to the adjustment holes, and a positioning pin passes through the positioning hole and the adjustment hole. By inserting the positioning pin into the adjustment holes of different heights, the floor height position of the placement plate can be quickly changed. The structure is simple and the adjustment is reliable.

[0007] Preferably, the lifting mechanism includes a winch and a reversing pulley fixedly installed on the top of the column, and a C-shaped sliding rod fixedly installed on the front side of the column. A portal-shaped hanging plate is slidably installed on the C-shaped sliding rod. The traction rope of the winch passes around the reversing pulley and is fixedly connected to the portal-shaped hanging plate. The loading and unloading mechanism is installed on the portal-shaped hanging plate. The winch, in conjunction with the guide of the sliding rod, ensures smooth lifting and lowering of the loading and unloading mechanism, facilitating the transport of goods from a higher level to a lower operating position.

[0008] Preferably, the retrieval and placement mechanism includes a lifting platform, a retrieval telescopic assembly, a push connecting rod, and a support plate. The retrieval telescopic assembly is fixedly installed on the top of the lifting platform. The free end of the retrieval telescopic assembly is fixedly connected to the support plate via the push connecting rod. The support plate is slidably engaged with the lifting platform. Protective plates are fixedly installed on the top front side and both sides of the support plate. A placement telescopic assembly is fixedly installed on the protective plates, and a push plate is fixedly installed on the telescopic end of the placement telescopic assembly. The retrieval telescopic assembly can drive the support plate to extend into the bottom of the cargo box to retrieve the goods, while the placement telescopic assembly can push the goods onto the placement plate. The protective plates can limit the movement of the goods, preventing them from slipping during storage and retrieval.

[0009] Preferably, the guide rails are fixedly installed on the top left and right sides of the placement plate, extending along the depth of the placement plate. One end of the guide rail near the edge of the placement plate has an outwardly expanding guide flare, and the other end of the placement plate away from the positioning component has a limiting baffle. The guide flare facilitates the introduction of the cargo box, and the limiting baffle acts as a blocking and positioning mechanism during placement, helping the cargo to be accurately positioned.

[0010] Preferably, the placement plate has an insertion compartment at one end near the positioning component. The positioning component includes a spring and a triangular insertion plate. The spring is fixedly installed on the inner wall of the insertion compartment, and the front end of the spring is fixedly connected to the triangular insertion plate. The triangular insertion plate extends through to the front end of the placement plate, and both the upper and lower surfaces of the triangular insertion plate are inclined. The rear end of the lifting platform is clearance-fitted with the front end of the placement plate, and the rear end of the lifting platform has a docking slot adapted to the triangular insertion plate. When the lifting platform is raised to be flush with the placement plate, the triangular insertion plate engages with the docking slot under the action of the spring, providing a positioning indication and temporary locking, allowing the operator to know the alignment status and improving docking accuracy.

[0011] Preferably, the column has graduations along its height, and these graduations correspond to the positions of the adjustment holes. A viewing window is provided on the side of the sliding sleeve closest to the graduations. Observing the graduations through the viewing window helps operators quickly adjust the placement plate to the desired height, reducing repeated adjustments.

[0012] Preferably, a top plate is fixedly installed at the top of the upright, and casters are fixedly installed at the bottom of the upright. Four uprights are arranged vertically in a rectangular array. The casters facilitate the movement and turning of the entire shelving unit, improving its flexibility of use.

[0013] Preferably, a connecting strap is attached to one side of the positioning pin, and the other end of the connecting strap is fixedly connected to the outer wall of the sliding sleeve. The connecting strap prevents the positioning pin from being lost after disassembly, facilitating its access and management.

[0014] Preferably, both the picking-up telescopic assembly and the placing telescopic assembly are electric push rods or hydraulic cylinders. A limiting groove is formed at the bottom of the placing plate, and a limiting slider is fixedly installed at the bottom of the triangular insert plate. The limiting slider slides in cooperation with the limiting groove. The cooperation between the limiting slider and the limiting groove prevents the triangular insert plate from overextending or shifting, ensuring the stability and reliability of its operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a three-dimensional warehouse rack that facilitates the storage and retrieval of goods. By setting up a spacing adjustment mechanism, the placement plates can slide up and down along the uprights and be locked at different heights by positioning pins in adjustment holes, allowing for flexible adjustment of the spacing between each layer according to the actual height of the stored goods. Compared with racks with fixed layer spacing, this structure is beneficial for making full use of vertical storage space, reducing volume waste caused by mismatched layer heights, and improving the space utilization rate of the rack to a certain extent.

[0016] 2. This utility model provides an automated warehouse racking system that facilitates the storage and retrieval of goods. A lifting mechanism drives the picking and placing mechanism to rise and fall, and in conjunction with picking and placing telescopic components, goods can be pushed in and taken out, allowing high-level goods to be lowered for operation. This design helps reduce the risk of high-altitude operations for personnel, alleviates the labor intensity of storage and retrieval operations, and improves the convenience and efficiency of high-level goods storage and retrieval operations.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 6 As shown, the present invention provides a three-dimensional warehouse rack for easy storage and retrieval of goods, including four vertically arranged columns 1 in a rectangular array and multi-layer placement plates 2 set on the columns 1. It also includes a spacing adjustment mechanism 3, a lifting mechanism 4 and a picking and placing mechanism 5. The top of the four columns 1 is fixedly installed with a top plate 13, and the bottom of the columns 1 is fixedly installed with universal wheels 12 with locking function to facilitate the movement and fixation of the entire rack. The front side of the columns 1 is the goods picking and placing operation side. The placement plates 2 are slidably connected to the columns 1 through the spacing adjustment mechanism 3. The lifting mechanism 4 is set on the top of the columns 1 and is used to drive the picking and placing mechanism 5 to lift and lower. The picking and placing mechanism 5 is movably set on the front side of the columns 1.

[0021] like Figure 2 As shown, each column 1 has multiple adjustment holes 11 spaced apart along the height direction. The adjustment holes 11 are circular through holes and are evenly distributed along the length of the column 1. At the same time, the front surface of the column 1 has a scale mark 14 along the height direction. The scale mark 14 corresponds to the position of the adjustment hole 11 and is used to indicate the current height value. C-shaped slide rods 43 are also fixedly installed on the front side of the two columns 1 located on the front side of the four columns 1. The opening of the C-shaped slide rod 43 faces forward, and its vertical section is located on the front side of the spacing adjustment mechanism 3 to avoid interference with the spacing adjustment mechanism 3.

[0022] like Figure 1 and Figure 3 As shown, the spacing adjustment mechanism 3 includes a sliding sleeve 31, which is a square sleeve that is slidably fitted onto the corresponding column 1. The four corners of each placement plate 2 are fixedly connected to the side walls of the four sliding sleeves 31, allowing the placement plate 2 to slide up and down along the column 1 with the sliding sleeves 31. The sliding sleeves 31 have positioning holes 32 corresponding to the adjustment holes 11. The positioning holes 32 are through holes with the same diameter as the adjustment holes 11. A positioning pin 33 passes through the positioning hole 32 and the corresponding height adjustment hole 11. Positioning pin 33 is a cylindrical pin used to lock the position of sliding sleeve 31 on column 1. One side of positioning pin 33 is connected to connecting strap 34, and the other end of connecting strap 34 is fixedly connected to the outer wall of sliding sleeve 31 to prevent positioning pin 33 from being lost after disassembly. A through-hole visual window 35 is provided on the side of sliding sleeve 31 near scale mark 14. The visual window 35 is a rectangular opening, through which the scale mark 14 on column 1 can be observed, thereby assisting the operator to quickly adjust sliding sleeve 31 to the required height.

[0023] Specifically, a wear-resistant bushing or a lubricating layer is provided between the inner wall of the sliding sleeve 31 and the outer wall of the column 1 to reduce sliding friction and extend service life; the positioning pin 33, the adjusting hole 11 and the positioning hole 32 are all clearance fit to ensure reliable locking and smooth insertion and removal.

[0024] like Figure 4 As shown, the lifting mechanism 4 includes a winch 41 and a reversing pulley 42 fixedly installed on the top of the top plate 13. The winch 41 is an electric winch, and the free end of its traction rope passes over the reversing pulley 42 and extends downward. The C-shaped slide bar 43 is a vertical slide rail made of C-shaped steel, and its opening faces the front of the shelf. A portal-shaped hanging plate 44 is slidably installed on the two C-shaped slide bars 43. The portal-shaped hanging plate 44 is inverted U-shaped, including a horizontal section and two vertical sections. The two vertical sections are respectively slidably engaged with the C-shaped slide bars 43 on both sides. After the traction rope of the winch 41 passes over the reversing pulley 42, its free end is fixedly connected to the middle position of the top of the horizontal section of the portal-shaped hanging plate 44. When the winch 41 is started, the traction rope is wound or released, driving the portal-shaped hanging plate 44 to rise and fall along the C-shaped slide bar 43. The pick-up and drop mechanism 5 is fixedly installed between the two vertical sections of the portal-shaped hanging plate 44, so as to rise and fall synchronously with the portal-shaped hanging plate 44.

[0025] Specifically, the winch 41, the picking telescopic assembly 52, and the unloading telescopic assembly 56 are all electrically connected to a controller. The controller is fixedly installed on the side wall of the column 1. The controller is electrically connected to an operating handle or a touch panel to control the forward and reverse rotation of the winch 41 and the telescopic movement of each telescopic assembly, so as to achieve coordinated control of lifting and picking operations. The surface of the C-shaped slide bar 43 is provided with a lubrication groove, and the sliding mating surface of the gantry plate 44 is fitted with ball bearings or graphite sliders to ensure smooth lifting without jamming.

[0026] like Figure 5As shown, the picking and placing mechanism 5 includes a lifting platform 51, a picking telescopic assembly 52, a pushing connecting rod 53, and a support plate 54. The lifting platform 51 is a horizontal plate structure. A gap is left between its rear end, i.e., the end closest to the column 1, and the front end of the placing plate 2. This gap is adapted to the triangular insert plate 232 of the positioning assembly 23. A docking slot 511 is provided at the rear end of the lifting platform 51. The docking slot 511 is a rectangular groove, and its position corresponds to the triangular insert plate 232. The picking telescopic assembly 52 is fixedly installed on the top of the lifting platform 51. The length of the cargo-retrieving telescopic component 52 is aligned with the front-rear direction of the lifting platform 51. The cargo-retrieving telescopic component 52 is an electric push rod or a hydraulic cylinder. Its fixed end is fixed to the top of the lifting platform 51, and its free end, i.e., the telescopic end, is fixedly connected to a push connecting rod 53. The push connecting rod 53 is a horizontal connecting rod located above the lifting platform 51, and its other end is fixedly connected to the rear end of the support plate 54. The support plate 54 is a rectangular flat plate, and its bottom surface slides in cooperation with the top surface of the lifting platform 51. It can be lifted relative to the lifting platform 51 under the drive of the cargo-retrieving telescopic component 52. The platform 51 moves back and forth, and the support plate 54 is positioned at one end near the placement plate 2, i.e., the rear end is set in a sloping shovel shape. The thickness of the wedge-shaped end of the support plate 54 is less than the gap between the cargo box and the bottom edge of the placement plate 2, making it easy to insert the cargo box into the bottom. The top front side of the support plate 54, i.e., the side away from the column 1, and the left and right sides are all fixedly installed with guard plates 55. The three guard plates 55 form a U-shaped limiting space to limit the box placed on the support plate 54 and prevent it from slipping during movement. The front surface of the guard plate 55 on the front side is... A loading telescopic assembly 56 is fixedly installed. The loading telescopic assembly 56 is also an electric push rod or a hydraulic cylinder. Its telescopic end passes through the front guard plate 55 and extends to the top of the support plate 54. A push plate 57 is fixedly installed at the end of the telescopic end. The push plate 57 is a vertical flat plate. Its left and right sides are respectively attached to the opposite inner sides of the left and right guard plates 55, thereby restricting the push plate 57 to move only in the front and back direction. When the loading telescopic assembly 56 extends, the push plate 57 pushes the cargo box backward, pushing it from the support plate 54 to the placement plate 2.

[0027] Specifically, linear slide rails are fixedly installed on the top left and right sides of the lifting platform 51, and a slider that slides with the linear slide rails is fixedly installed on the bottom of the support plate 54. The linear slide rails extend in the front and rear direction, and a limit stop is provided at the front end to prevent the support plate 54 from extending excessively. An anti-loosening gap adjustment screw is provided between the slider and the linear slide rail to adjust the sliding tightness.

[0028] like Figure 1 , Figure 5 and Figure 6As shown, guide rails 21 are fixedly installed on the top left and right sides of the placement plate 2. The guide rails 21 extend along the longitudinal direction of the placement plate 2, that is, the front-to-back direction. The distance between the two guide rails 21 is adapted to the width of the box being stored. The end of the guide rail 21 near the front edge of the placement plate 2 has an outwardly expanding guide flare, which is funnel-shaped, to facilitate the introduction of the box from the front. At the rear end of the placement plate 2, that is, the end away from the picking and placing mechanism 5, a limit baffle 22 is fixedly installed. The limit baffle 22 is a vertical baffle, which is used to limit the box when it is placed, so that the box is accurately positioned. A positioning component 23 is provided at the front end of the placement plate 2, that is, at the end near the pick-and-place mechanism 5. Specifically, an insertion plate compartment 24 is provided inside the front end of the placement plate 2. The insertion plate compartment 24 is a rectangular cavity extending in the front-rear direction, and its front end opens onto the front end face of the placement plate 2. A limiting slide groove 25 is provided on each of the left and right sides of the bottom of the placement plate 2. The limiting slide groove 25 extends in the front-rear direction and penetrates into the inner cavity of the insertion plate compartment 24. The positioning component 23 includes a spring 231 and a triangular insertion plate 232. The spring 231 is a compression spring, and there are several of them, which are fixedly installed on the inner wall of the rear end of the insertion plate compartment 24. The front end of spring 231, i.e., the free end, is fixedly connected to the rear end of triangular insert 232. Triangular insert 232 is a wedge-shaped plate extending in the front-rear direction, with its front end extending through to the outside of the front end of the placement plate 2. Both the upper and lower surfaces of triangular insert 232 are inclined, i.e., its front end is thinner and its rear end is thicker, forming an overall triangular wedge shape. A limit slider 233 is fixedly installed at the bottom of triangular insert 232. The limit slider 233 slides with the limit groove 25 to restrict the triangular insert 232 to move only in the front-rear direction, preventing it from overextending or deviating. When the lifting platform 51 rises to a certain position... When the first-layer placement plate 2 is aligned, the rear end of the lifting platform 51 and the front end of the placement plate 2 are fitted with a clearance. At this time, the triangular insert plate 232 extends forward under the elastic force of the spring 231 and is inserted into the docking slot 511 at the rear end of the lifting platform 51, making a clicking sound. At the same time, it temporarily locks the position, so that the operator can know that the lifting platform 51 and the placement plate 2 are accurately aligned. When the lifting platform 51 continues to rise or fall, the rear end face of the lifting platform 51 presses against the upper or lower inclined surface of the triangular insert plate 232, causing the triangular insert plate 232 to overcome the elastic force of the spring 231 and retract into the insert plate compartment 24, thus releasing the lock.

[0029] Specifically, the inclination angles of the upper and lower inclined surfaces of the triangular insert 232 are both 30° to 60°, so that when the rear end face of the lifting platform 51 presses against the inclined surface, the resulting horizontal component force is sufficient to overcome the elastic force of the spring 231, ensuring that the triangular insert 232 retracts smoothly when the lifting platform passes through a non-target layer; the preload of the spring 231 is 5N to 15N, ensuring that the triangular insert 232 can pop out and engage with the docking slot 511 after the lifting platform is in position.

[0030] Furthermore, the winch 41, the picking telescopic assembly 52, and the unloading telescopic assembly 56 are all electrically connected to a controller. The controller is fixedly installed on the side wall of the column 1 and is electrically connected to an operating handle or a touch panel for controlling the forward and reverse rotation of the winch 41 and the telescopic movement of each telescopic assembly, so as to realize the control of lifting and picking / unloading operations.

[0031] The working principle of this automated warehouse racking system, which facilitates the storage and retrieval of goods, will be explained in detail below.

[0032] like Figure 1-6As shown, firstly, the spacing of each layer of placement plates 2 is adjusted according to the height of the boxes to be stored. The operator, referring to the scale markings 14 on the column 1, observes the current height position of the sliding sleeve 31 through the visualization window 35, based on the box height. The positioning pin 33 is then pulled out of the positioning hole 32 and adjustment hole 11, allowing the sliding sleeve 31 to slide freely along the column 1. The sliding sleeve 31 is moved up or down to the target height, aligning the positioning hole 32 with the corresponding adjustment hole 11. Then, the positioning pin 33 is reinserted into the positioning hole 32 and adjustment hole 11, completing the height locking of that layer of placement plate 2. The spacing of all placement plates 2 is adjusted in this way, ensuring that the height of each layer is slightly greater than the box height to improve space utilization. When a box needs to be stored on a certain layer of placement plate 2, the operator starts the winch 41. The winch 41's traction rope drives the gantry crane 44 down along the C-shaped slide bar 43 via the reversing pulley 42, thereby lowering the entire retrieval and placement mechanism 5 to near the height of the target placement plate 2. When the lifting platform 51 is aligned with the target placement plate 2, the triangular insert 232, under the action of the spring 231, engages in the docking slot 511, emitting a positioning prompt sound. At this point, the lifting platform 51 and the placement plate 2 are precisely aligned. Then, the box to be stored is placed on the support plate 54, positioning it within the limited space enclosed by the three guard plates 55. The loading telescopic assembly 56 is activated, extending its telescopic end and pushing the pusher plate 57 backward. The pusher plate 57 pushes the box backward along the support plate 54, guiding it through the guide flare of the guide rail 21 into the space between the two guide rails 21 on the placement plate 2. It continues to move backward until the rear end of the box abuts against the limiting baffle 22, at which point the box is fully pushed onto the placement plate 2. Then, the loading telescopic assembly 56 retracts, resetting the pusher plate 57. Finally, the winch 41 is controlled to raise the loading mechanism 5 to a safe height, completing the loading operation. When a box needs to be removed from a certain placement plate 2, the hoist 41 is first controlled to raise and lower the loading / unloading mechanism 5 to the height of the target placement plate 2, so that the triangular insert 232 engages with the docking slot 511 for alignment. Then, the loading telescopic assembly 52 is activated, and its free end extends, pushing the support plate 54 backward via the push connecting rod 53. The sloping, shovel-shaped rear end of the support plate 54 inserts into the bottom of the box until it is completely inserted under the box, while the protective plate 55 surrounds the front and left and right sides of the box. Then, the loading telescopic assembly 52 retracts, pulling the support plate 54 forward, and the box moves off the placement plate 2 with the support plate 54 and is completely moved above the lifting platform 51. Next, the hoist 41 is controlled to lower the loading / unloading mechanism 5 to a low position, such as the ground or a height easily accessible to the operator. At this point, the operator can safely and conveniently remove the box from the support plate 54. During the loading / unloading process, the box will not shift or slip due to the restraint of the protective plate 55.Throughout the lifting process, the rear end of the lifting platform 51 maintains a clearance fit with the front end of the placement plate 2. When the lifting platform 51 passes over a non-target placement plate 2, the upper or lower inclined surface of the triangular insert 232 is pressed by the rear end face of the lifting platform 51, and the triangular insert 232 automatically retracts into the insert compartment 24, without affecting the normal lifting of the lifting platform 51. When the lifting platform 51 reaches the target position and is accurately aligned, the triangular insert 232 automatically pops out and engages with the docking slot 511, achieving positioning and indication. The universal wheels 12 allow the entire rack to be moved to different work areas as needed, and the locking function ensures stability during use.
