Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing technology, and in particular to an automatic bar stock storage and retrieval system. Background Technology

[0002] In the smart warehouse management industry, the classification and retrieval of materials are often involved. Ordinary warehouses are generally managed by warehouse managers who classify, enter, and retrieve materials. These steps often require a lot of manpower and time.

[0003] In recent years, with the rapid development of the manufacturing industry and the transformation of modern production models, automated storage and retrieval systems (AS / RS) have become an important piece of equipment for manufacturing enterprises due to their low footprint, high operational efficiency, and intelligent features. AS / RS boasts high space utilization and superior inbound and outbound capabilities, facilitating efficient logistics and large-capacity storage. In today's rapidly developing logistics industry, it has become a crucial warehousing technology for enterprise logistics and production management. Furthermore, with the rapid development and intelligent transformation of the manufacturing industry, AS / RS have gained significant popularity among manufacturing enterprises due to their low footprint, high operational efficiency, and intelligent features.

[0004] Long steel pipes are widely used in industries such as machinery, construction, and logistics. However, due to their length and weight, these pipes are prone to bending, deformation, and shaking during transport and storage, resulting in low safety. Currently, most domestic manufacturers use natural stacking for storage; the few companies with automated warehouses mainly employ large-span double-column stacker cranes for storage and retrieval, which not only excessively occupies production space but also severely restricts production efficiency. While automated warehouses are more mature overseas, incorporating stacker cranes, robotic arms, and electromagnetic chucks, these systems are mostly suitable for small to medium-sized materials or plates, and are insufficient for storing and retrieving irregularly shaped, long, and heavy pipes.

[0005] Meanwhile, existing inventory management relies on traditional manual record-keeping, which is not only inefficient but also makes it difficult to recount inventory once items are received, and errors are hard to detect in a timely manner. Furthermore, manual record-keeping cannot provide real-time updates on pipe inventory, easily leading to difficulties in procurement decisions and inaccurate quantities. Utility Model Content

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0042] like Figures 1-11 The diagram shows an automated bar stock storage silo. The footprint of the equipment is determined based on the actual site size, including a foundation that provides a stable base for the entire automated storage silo, bearing the weight of all equipment and dynamic loads during operation. A cutting roller conveyor 4 is installed on one side of the foundation, located at the silo entrance, to receive bar stock cut from the upstream process and transport it to the bar stock placement roller conveyor 2. An unloading roller conveyor 5 is installed on the other side of the automated gripping device 1, located at the silo exit, to receive bar stock removed from the bar stock placement assembly 3 and transport it to the downstream process. The foundation is equipped with…

[0043] The bar stock placement component 3 constitutes the main storage unit of the warehouse. It consists of several bar stock placement racks and is used for long-term and orderly storage of bar stock of different specifications or batches.

[0044] The bar stock placement roller conveyor 2 serves as a platform for placing bar stock when it enters or leaves the warehouse. It moves the bar stock left and right away from the positioning bar stock position and is installed at one end of the bar stock placement assembly 3.

[0045] The intelligent identification system identifies the model of the bar stock and records the data. Each bar stock in each position on the bar stock placement component 3 corresponds to the data in the system. When the bar stock is needed, the automatic gripping device 1 will move to the corresponding position to grab it according to the system data.

[0046] Automatic gripping device 1 is used to automatically grip the bar stock on the bar stock placement roller 2 and send the bar stock to the corresponding storage position of the corresponding bar stock placement component 3;

[0047] The system includes an automatic trolley 11 and a rotatable lifting device 14. The automatic trolley 11 travels along the length of the bar storage and placement assembly 3. The rotatable lifting device 14 is mounted on a crossbeam of the automatic trolley 11. Lifting guide rails 12 are installed on both sides of the automatic trolley 11 along the length direction to provide precise vertical guidance for the lifting movement of the device 14. A lifting assembly 13 is installed on the top of the automatic trolley 11. The lifting assembly 13 provides power and control to drive the device 14 to lift vertically along the lifting guide rails 12. The lifting assembly 13 is connected to the rotatable lifting device 14 to drive the rotatable lifting device 14 to lift along the lifting guide rails 12. The lifting guide rails 12 also prevent the rotatable lifting device 14 from swaying.

[0048] 2 such as Figure 2 As shown, the rotatable lifting device 14 directly performs the operations of grabbing, lifting, rotating and releasing bar materials. The rotatable lifting device 14 includes a mounting frame 141, which is connected to the lifting guide rail 12 and serves as the mounting base for other components. It spans the width of the warehouse. Both ends of the mounting frame 141 are equipped with pulley assemblies 142 that cooperate with the lifting assembly 13. The pulley assemblies 142 cooperate with the lifting guide rail 12 to ensure that the lifting device 143 moves smoothly and vertically during the lifting process and prevents swaying. Both ends of the mounting frame 141 are equipped with lifting lugs 144 that are connected to the hoist hooks 134 of the lifting assembly 13 to transmit the lifting force. Several lifting devices 143 are installed on the mounting frame 141.

[0049] The lifting device 143 includes a rotary motor 1431 and a rotary support 1432. The rotary motor 1431 provides power and is mounted on the mounting frame 141 via a mounting base. The output end of the rotary motor 1431 is connected to the rotary support 1432 to drive the rotary support 1432 to rotate 180° to adjust the direction of the bar stock. For example, after being horizontally removed from the bar stock placement rack, it can be rotated 90° or 180° to facilitate placement on the bar stock placement roller conveyor 2 or to adapt to the cantilever 33 in different directions.

[0050] like Figure 3 As shown, the rotating bracket 1432 transmits the torque of the rotating motor 1431. The rotating bracket 1432 includes a connecting column 14321 and a connecting frame 14322. One end of the connecting column 14321 is connected to the rotating motor 1431. The connecting frame 14322 is set horizontally with the ground. The other end of the connecting column 14321 is connected to one side of the connecting frame 14322. A V-shaped bracket 14323 is installed on the top surface of the other side of the connecting frame 14322. The V-shaped bracket 14323 supports the bar stock. Its V-shaped design can naturally center and position the cylindrical bar stock, providing a stable support point and facilitating loading and unloading. The width of the connecting frame 14322 is greater than the width of the mounting crossbeam 141. The installation position of the V-shaped bracket 14323 extends beyond the mounting crossbeam 141 to avoid interference.

[0051] The automatic gripping device 1 is the core actuator of the entire storage warehouse, responsible for automatically and accurately gripping, transporting and placing bar stock between the bar stock placement roller conveyor 2 and the bar stock placement assembly 3, as well as between different positions inside the bar stock placement assembly 3.

[0052] like Figure 4 As shown, the automated guided vehicle 11 provides a wide range of movement for the rotatable lifting device 14 in the length direction (X-axis) and height direction (Z-axis) of the warehouse, and bears the weight of the rotatable lifting device 14 and the bar stock. The automated guided vehicle 11 includes a truss 111, which is a gantry crane type, the main load-bearing structure, spans the width of the warehouse, and bears all loads. Both sides of the top of the truss 111 are equipped with hanging end beams 112, and both sides of the bottom of the truss 111 are equipped with end beam assemblies 113.

[0053] like Figure 7 As shown, the under-mounted end beam 112 includes an end beam frame 1121. The end beam frame 1121 has an opening in the middle. Passive wheels 1122 that cooperate with the upper guide rail 16 in the automatic gripping device 1 are installed on both inner sides of the opening of the end beam frame 1121. The passive wheels 1122 cooperate with the upper guide rail 16 to guide the automatic trolley 11 to run smoothly along the X-axis direction and mainly bear the horizontal force. End beam rollers 1123 that support the upper guide rail 16 in the automatic gripping device 1 are installed at both ends of the bottom surface of the end beam frame 1121. The end beam rollers 1123 are supported on the upper guide rail 16 and mainly bear the vertical load. Buffers 1124 are installed at both ends of the end beam frame 1121 to absorb collision energy when the automatic trolley 11 approaches the end of the track, prevent hard impact, and protect the equipment and structure.

[0054] like Figure 6As shown, the end beam assembly 113 is installed on both sides of the bottom of the truss 111. The end beam assembly 113 includes an end beam 1131. Both ends of the end beam 1131 are equipped with traveling wheels that roll on the lower guide rail 19, directly bearing the vertical load of the automatic trolley 11 and providing running guidance in the X-axis direction. A mounting seat is installed on one side of the end beam 1131, and a drive motor 1133 is installed on the mounting seat to provide power to the traveling wheels and drive the entire trolley to move along the X-axis direction. The output end of the drive motor 1133 is connected to a traveling wheel to drive the traveling wheel to slide on the lower guide rail 19 in the automatic gripping device 1. Both ends of the end beam 1131 are provided with anti-collision blocks 1134 to protect the end of the automatic trolley 11's stroke. These blocks cooperate with the anti-collision blocks 10 at the end of the guide rail to provide double anti-collision protection.

[0055] The automatic gripping device 1 also includes an upper guide rail 16 installed on top of the discharge hopper and a rail support groove 17 cut into the foundation. The upper guide rail 16 provides a high-level running track for the lower-mounted end beam 112 of the automatic crane 11. The rail support groove 17 is a pre-fabricated groove in the foundation for precisely installing the rail support beam 18. The rail support beam 18 is installed in the rail support groove 17, and the rail support beam 18 firmly supports and installs the lower guide rail 19, providing a solid, flat, and precise low-level running track for the wheels of the crane end beam assembly 113. This is the main load-bearing track of the automatic crane 11. The lower guide rail 19, which cooperates with the end beam assembly 113, is installed on the support beam 18. It is the running track of the traveling wheels in the end beam assembly 113 of the automatic trolley 11. It directly bears most of the vertical load of the trolley and provides precise X-axis guidance. Both ends of the support beam 18 are equipped with anti-collision blocks 10, which cooperate with the anti-collision blocks 1134 on the end beam assembly 113 of the trolley. When the automatic trolley 11 runs to the limit position of the track, it absorbs the collision energy, forces the trolley to stop, and prevents the trolley from derailing or damaging the equipment.

[0056] like Figure 5 As shown, a positioning system 6 is also installed on both sides of the foundation to determine the real-time position. The positioning system includes a detection part and a sensing part that are configured in conjunction. The detection part is installed on the middle beam assembly 113 of the automatic gripping device 1.

[0057] The detection part includes a sweeping dock support 61, on which a communication client 62 and a positioning sensor 63 are installed, which are the core detection components.

[0058] The sensing part includes a bracket 64 installed on the foundation. The bracket 64 is arranged along the length direction of the bar stock placement assembly 3. The bracket 64 is provided with a barcode strip 65 and a leakage cable 66 that cooperate with the positioning sensor 63. The barcode strip 65 carries position information. The positioning sensor 63 reads the barcode strip 65 or interacts with the leakage cable 66 to sense the current position of the vehicle and can obtain discrete, high-precision absolute position.

[0059] Leaky wave cable 66 provides continuous, real-time position feedback. The combination of barcode tape 65 and leaky wave cable 66 is typically used to achieve high-precision, high-reliability absolute position detection.

[0060] The sensing and detection components are connected to the receiver in the ground control cabinet via a signal connection. This connection provides strong anti-interference capabilities and stable signal transmission, and is responsible for the signal communication between the automatic crane's action signals and the ground control cabinet. Figure 8 As shown, the bar stock placement roller conveyor 2 includes a roller transport frame 21 and a drive unit. The roller transport frame 21 is used to support and install the structure of the power rollers 22. Several power rollers 22 are mounted on the roller transport frame 21. The bar stock is driven to move left and right on the roller conveyor by rotation. Each power roller 22 has a sprocket 23 mounted on its roller shaft. Each sprocket 23 is connected to the others by a chain. The output end of the drive unit (not shown in the figure) is connected to the chain to drive the chain to drive all the power rollers 22 together, so as to achieve synchronous drive. The power is provided by a single drive unit.

[0061] The bar stock placement roller conveyor 2 serves as a temporary transfer platform for bar stock entering and leaving the warehouse.

[0062] Upon entry into the warehouse, the bar stock fed from the cutting roller conveyor 4 is received and positioned in a position that can be grasped by the automatic gripping device 1.

[0063] When the bar is removed from the bar placement rack by the automatic gripping device 1, it is moved to a position that facilitates its transport to the unloading roller conveyor 5.

[0064] The structures of the feeding roller conveyor 5 and the cutting roller conveyor 4 are the same as those of the bar stock placement roller conveyor 2.

[0065] like Figure 9As shown, the bar stock storage rack is used for storing bar stock. It features a multi-layer, double-sided design, and the number of racks can be set according to actual needs. For example, a single rack can store 54 bars, with a maximum length of 12m, a minimum length of 3m, and a maximum diameter of 15mm. Each storage location can simultaneously store 1-4 bars of different lengths, maximizing storage capacity. Based on all 12m long bars, it can store 54 * 15.5 = 837 bars. If bars of different lengths are stored together, the storage capacity can be even greater. The rack includes symmetrically arranged column bases 31, which are fixed to the foundation, providing stability to the bar stock storage rack. The support consists of several columns 32 installed between the two column bases 31. The columns 32 are vertical support mechanisms that form the main frame of the bar placement rack. The columns 32 and the column bases 31 are connected as one unit by crossbars, which enhances the overall rigidity and stability of the frame. Each column 32 has cantilever arms 33 installed on both sides of its column body for placing bars, supporting and bearing the bars. The cantilever design of the cantilever arms 33 makes it easy for the rotatable lifting device 14 to pick up and put down the bars from below or the side. Adjacent columns 32 are connected by several sets of reinforcing components to ensure that the bars are stored stably, are easy to access, and have high space utilization.

[0066] like Figure 10 As shown, the reinforcing assembly connects adjacent columns 32 to form a truss structure, which greatly enhances the deformation resistance of the entire bar stock in the length and height directions, ensuring structural safety when storing large quantities of heavy bar stock. The reinforcing assembly includes two horizontal braces 34, which form a reinforcing area with the adjacent columns 32. The four corners of the reinforcing area are connected to turnbuckles 36 via diagonal braces 35. The turnbuckles 36 are used to adjust the tension of the diagonal braces 35.

[0067] like Figure 11 As shown, the lifting assembly 13 includes a lifting mounting base 131. A winch 132 is installed on one side of the lifting mounting base 131 to wind up and unwind the wire rope, providing the power source for lifting. A fixed pulley block 133 is installed on the other side of the lifting mounting base 131 to change the direction of the wire rope, forming a pulley assembly system, which can increase the lifting force or reduce the required motor power. One end of the cable in the winch 132 passes around the fixed pulley block 133 and is fixed to the lifting mounting base 131. A hoist hook 134 is provided on the cable between the winch 132 and the fixed pulley block 133. An encoder for determining the lifting height is installed on the hoist hook 134 to provide precise position feedback to the control system.
