[0028] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0029] like Figure 1-Figure 7 As shown, a long rod stereoscopic warehouse in one embodiment of the present invention includes a storage mechanism 1 and a transfer device 2; the storage mechanism 1 includes a base frame 11 and a plurality of material separation columns 12 installed vertically on the base frame 11 at intervals, and a stacking space is formed between two adjacent material separation columns 12; the transfer device 2 includes a shift frame 21, a transverse platform 22 and a transfer assembly 23, the shift frame 21 is provided with a guide rail 211, the guide rail 211 is provided with a guide groove 2111, and the transverse platform 22 slides through the roller 221 The movable assembly is on the guide rail 211, and the roller 221 is provided with a protrusion 2211 on the circumference thereof which is adapted to the guide groove 2111. The transfer assembly 23 is installed on the transverse platform 22, and the transfer assembly 23 is provided with a clamping member 231 which can be raised and lowered relative to the transverse platform 22. Two clamps 232 are rotatably installed on the clamping member 231, and the clamp 232 is provided with a supporting part 2321 for lifting the bar material 5. A clamping space is formed between the two clamps 232, and the diameter of the clamping space is smaller than the diameter of the stacking space.

[0030] The above-mentioned long rod three-dimensional warehouse is convenient for forming multiple stacking spaces by providing multiple material partition columns 12, which is conducive to vertical stacking and classification of rods 5 of various types or sizes. It is convenient for storage and access and occupies a smaller area, solving the problem that the traditional flat storage method of rods 5 occupies a large area and has low material retrieval efficiency; by providing guide grooves 2111 and protrusions 2211, the roller 221 can be adapted to the guide rail 211, effectively preventing the roller 221 from falling off the guide rail 211, which is conducive to ensuring its stability during the movement of the transverse platform 22; by providing a supporting part 2321, the freedom of the rod 5 is limited during the clamping process, which plays a positioning role; by the diameter of the clamping space being smaller than the diameter of the stacking space, the clamping space can reciprocate into the stacking space to complete the storage and access of the rods 5, avoiding the damage of the rods 5 caused by collisions between the rods 5 caused by the discharge of the rods 5 from a high place, and can also better complete the grasping of the rods 5 in the stacking space.

[0031] Specifically, the material separation columns 12 are arranged vertically to facilitate the vertical stacking of the bars 5.

[0032] Specifically, the guide rail 211 is arranged in a horizontal direction.

[0033] Furthermore, a maintenance platform is provided on the top of the traverse platform 22 to facilitate operators to disassemble and maintain the transfer device 2.

[0034] like Figure 1 and Figure 7 As shown, in one embodiment, the base frame 11 is composed of several welded bottom frames, with mounting beams connecting adjacent bottom frames. A column group is threadedly fixed to the top of each mounting beam. Each column group includes multiple material separation columns 12, and the top of the material separation columns 12 is provided with a trapezoidal portion. The trapezoidal portion has a geometric feature of being narrow at the top and wide at the bottom, which is more conducive to the reciprocating entry and exit of the rod 5 along the direction in which the material separation columns 12 are set, thereby reducing the collision between the rod 5 and the material separation columns 12.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment, a guide groove 2111 is provided at the top of the guide rail 211, and a rack 212 is provided at the bottom of the guide rail 211. A drive structure is connected to the traversing platform 22, and the drive structure includes a first drive motor 222, a rotating shaft 223, and a transmission gear 224 that meshes with the rack 212. The output end of the first drive motor 222 is in transmission connection with one end of the rotating shaft 223, and the transmission gear 224 is sleeved on the other end of the rotating shaft 223. By providing the first drive motor 222, the first drive motor 222 controls the rotation of the rotating shaft 223, thereby controlling the rotation of the transmission gear 224. The meshing relationship between the transmission gear 224 and the rack 212 drives the roller 221 to slide on the guide rail 211, and ultimately achieves the position adjustment of the traversing platform 22 along the direction in which the guide rail 211 is set.

[0036] Preferably, the first drive motor 222 is a servo motor, specifically Siemens 1FL609X-1AC61, which ensures that the transverse platform 22 moves smoothly and positions accurately.

[0037] like Figure 6 and Figure 7As shown, in one embodiment, the transfer assembly 23 includes a limiter 233, a second drive motor 234, and a lifting structure. The limiter 233 is fixed to the bottom of the traversing platform 22. The limiter 233 is provided with a limiter structure for abutting the clamping member 231. The second drive motor 234 is mounted on the traversing platform 22. The output end of the second drive motor 234 is transmission-connected to one end of the lifting structure and is used to control the lifting of the lifting structure. The other end of the lifting structure is fixedly connected to the clamping member 231. By providing the second drive motor 234, the second drive motor 234 controls the lifting movement of the lifting structure, thereby enabling the clamping member 231 to perform a reciprocating lifting and lowering action, thereby adjusting the clamping height of the clamping member 231 and improving the accuracy of clamping the bar 5.

[0038] Preferably, the second drive motor 234 is a reduction motor, specifically a NMRV motor with brake from Starlight Transmission, which is more efficient in driving the load.

[0039] Furthermore, the lifting and lowering motion of the clamping member 231 is driven by a worm gear reduction motor and a frequency converter. The lifting mechanism has a worm gear self-locking protection device, which prevents the lifting mechanism from falling if the power is suddenly cut off during movement. This is prior art and will not be elaborated on in detail.

[0040] like Figure 5 and Figure 7 As shown, in one embodiment, the clamping member 231 includes a main rod 2311, a hinge seat 2312 and two positioning plates 2313 arranged on both sides of the main rod 2311, the main rod 2311 is fixedly connected to the lifting structure, the hinge seat 2312 is fixed on the main rod 2311, the two clamps 232 are rotatably assembled on the hinge seat 2312, and the positioning plates 2313 abut against the inner wall of the limiting member 233; the limiting structure includes a connecting block 2331, a third driving motor 2332 and a limiting head 2333, the connecting block 2331 is detachably fixed on the limiting member 233, the third driving motor 2332 is installed on the connecting block 2331 and is used to control the swing of the limiting head 2333, and the limiting head 2333 abuts against the top of the main rod 2311. By providing a third drive motor 2332, the third drive motor 2332 controls the rotation of the limit head 2333 and enables it to adjust the setting angle to adapt to the height position of the main rod 2311. When the limit head 2333 abuts and collides with the main rod 2311, the operator can detect the situation and limit the continued rise of the clamping member 231. The technical means for issuing a warning or alarm after the limit head 2333 collides with the main rod 2311 are existing technologies and will not be elaborated on here.

[0041] Preferably, the clamp 232 is a pneumatic clamp 232. The bar 5 is clamped and positioned using compressed air pressure, which is simple to operate and highly efficient. The pneumatic clamp 232 can simultaneously withstand loads from multiple directions, ensuring high-precision positioning and movement, and is suitable for production environments with frequent operations.

[0042] like Figure 5 As shown, in one embodiment, the clamp 232 includes a rotating portion 2322 and an extended clamp portion 2323. One end of the rotating portion 2322 is rotatably mounted on the hinge seat 2312, and the other end of the rotating portion 2322 is rotatably connected to the extended clamp portion 2323. The support portion 2321 is disposed at the bottom of the extended clamp portion 2323 and is integrally formed with the extended clamp portion 2323. This integrated molding significantly reduces production processes and time, and provides higher structural strength.

[0043] In one embodiment, the stacking space is square in shape, with a semicircular clamping space for clamping the bar 5 formed between the two extended clamping portions 2323. The diameter of the clamping space is smaller than the width of the stacking space, making it easier for the clamp 232 to reciprocate into the stacking space and easily clamp and place the bar 5.

[0044] like Figure 1-Figure 3 As shown, in one embodiment, the long rod stereoscopic warehouse also includes a feeding mechanism 3, which includes a first rod storage rack 31 and a preparation rack 32. The top of the first rod storage rack 31 is provided with an inclined rod storage platform 311, and the two ends of the rod storage platform 311 are respectively provided with a feeding end and a discharging end at different heights. The discharging end is provided with a first material stopper 312 that can be raised and lowered relative to the rod storage platform 311. The preparation rack 32 is provided on one side of the discharging end, and the preparation rack 32 is located between the rod storage rack and the storage mechanism 1. When it is necessary to load the rods 5, the operator can control the height position of the first material stopper so that the rods 5 on the rod storage platform 311 can slide down to the preparation rack 32 in sequence under the action of gravity, completing the loading preparation and waiting for the subsequent transfer component 23 to clamp the rods 5 and transfer the loading.

[0045] like Figure 2 As shown, in one embodiment, two sets of supporting structures are symmetrically mounted on the preparation rack 32. The two sets of supporting structures are arranged opposite each other, and a loading space for the bar 5 is formed between the two sets of supporting structures. Each set of supporting structures includes a plurality of support blocks 321 arranged at intervals for supporting the bar 5. The symmetrical arrangement of the two sets of supporting structures ensures a symmetrical distribution of supporting force, which helps to improve the stability of the bar 5 when it is placed.

[0046] Specifically, the support blocks 321 are tilted. Symmetrical tilted support can reduce the gap between the support blocks 321 on both sides, thereby improving the stability of the bar 5 when supported and placed.

[0047] like Figure 1 and Figure 3 As shown, in one embodiment, the long rod storage bin further includes a discharge mechanism 4, which includes a second rod storage rack 41 and a rod pusher rack 42. The second rod storage rack 41 is provided with a second material stopper that can be raised and lowered relative to the second rod storage rack 41. The rod pusher rack 42 is arranged between the storage mechanism 1 and the second rod storage rack 41. The rod pusher rack 42 is provided with a discharge conveyor belt 421 adapted to the rods 5. The discharge conveyor belt 421 has a simple structure, low maintenance costs, and stable operation, reducing equipment maintenance costs, enabling continuous and efficient transportation, adapting to various transportation needs, and significantly improving production efficiency.

[0048] Preferably, the discharge conveyor belt 421 is made of high-strength heat-vulcanized rubber, which has excellent wear resistance, can maintain good conveying effect for a long time, and is suitable for various harsh working environments.

[0049] In another embodiment, the long-bar storage system further includes a data management system with a bar record sheet. The bar record sheet automatically records the specifications, quantity, and location of each bar 5 in the storage mechanism 1. Operators can monitor the entire system based on the bar record sheet and manually take over the operation of the transfer device 2 in specific circumstances.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
