DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] A three-dimensional storage system for cylindrical materials provided by an embodiment of the present invention improves the storage and retrieval efficiency of cylindrical materials 7 of various specifications stored in the same warehouse, realizes the single-piece handling of small-diameter cylindrical materials 7, and can effectively reduce the peak fluctuations in and out of the warehouse.

[0041] See also Figure 1 , a cylindrical material three-dimensional storage system, a storage module 1, a stacking module 2, a three-dimensional shelf module 3, a storage module 4 constitute a subsystem; the cylindrical material three-dimensional storage system can be composed of one or more subsystems, plus a storage control module, and the subsystems are connected in series through a main conveyor line 5. Figure 2 The schematic diagram of a cylindrical material three-dimensional storage system is shown, which shows one embodiment of the present invention, but not all embodiments. Each module can be organically arranged to form a variety of embodiments. This embodiment will be described in detail below.

[0042] The main conveyor line 5 is used to continuously convey cylindrical materials, and cylindrical materials 7 lie on it and are conveyed along the axis. It is composed of multiple chain plate conveyors. The panel of the conveying chain plate is V-shaped, which is convenient for efficient and continuous conveying of cylindrical materials 7. Its structure is shown in the Chinese patent document CN200320114102.3.

[0043] The stacking module 2 is used to pick up and place the transfer materials, and pick up and place the transfer materials between the storage module 1, the three-dimensional shelf module 3, and the outbound module 4 or in the three-dimensional shelf module 3. Figure 3It is a schematic elevation diagram of a stacking module. It shows that the stacker 21 as a whole runs horizontally along the X-axis, the cargo platform 22 rises and falls vertically along the Y-axis, and the fork 23 extends and retracts along the Z-axis. It shows that the fork 23 and the gripper 24 are installed on the cargo platform 22.

[0044] In stacking module 2, see Figure 4 Schematic diagram of the structure of the fork 23 and the V-shaped I-block. A plurality of I-shaped V-shaped blocks 231 are installed on the fork 23. The I-shaped V-shaped blocks 231 are used to support materials. Figure 5 To match the posture diagram of the fork 23 and the storage rack 31, the number, spacing, and size of the I-shaped V-shaped blocks 231 are matched one by one with the upper surface notches of the centering warehouse loader 13, the storage rack 31, and the warehouse unloader 41 of other modules.

[0045] Among them, it is used to store cylindrical materials 7 in three dimensions; in order to improve the storage space utilization rate of the three-dimensional shelf module 3, the height ratio of the three-dimensional shelf 32 can be arranged according to the material specification range ratio; at the same time, the distribution quantity of the storage shelf 31 is determined; see Figure 6 It is a partial elevation diagram of the three-dimensional shelf 32 module.

[0046] In the three-dimensional shelf module 3, the storage rack 31 is composed of a bent plate, a U-shaped rib plate, etc., and the upper surface forms a V-shaped structure for storing cylindrical materials 7, see Figure 7 The schematic diagram of the structure of the storage rack 31 of the three-dimensional shelf 32 module is shown in FIG. Figure 8 It is a cross-sectional view of the storage rack 31.

[0047] Among them, the storage control module reads the material information, and controls the main conveyor line 5 to transport the materials to the designated subsystem according to the preset warehousing rules; schedules the material buffer quantity on the warehousing module 1 and releases the materials one by one; controls the stacking module 2 in the subsystem to store the materials on the designated storage board in the three-dimensional shelf module 3 according to the preset storage rules; controls the stacking module 2 in the corresponding subsystem to move the materials on the designated storage board in the three-dimensional shelf module 3 to the outbound module 4 according to the demand information and the outbound rules; schedules the material buffer quantity on the outbound module 4, cooperates with the transportation of the main conveyor line 5, and releases the materials to the main conveyor line 5 one by one.

[0048] The operation mode of this embodiment is as follows:

[0049] 1. Buffer storage: The main conveyor line 5 conveys the cylindrical material 7 to the designated subsystem entrance. Fig. 9 It is a schematic diagram of the facade cache of the storage module 1, which shows that the storage module 1 includes two kick connectors 11, a distributor 12, and a centering storage device 13.

[0050] It shows that the ramp is arranged with a height difference, with the main conveyor line 5 at a high position, the distributor 12 at a middle position, and the centering storage device 13 at a low position. Under the action of gravity, the cylindrical material 7 rolls from the high position to the low position along the ramp.

[0051] It shows that the storage module caches materials. After the materials are delivered to the entrance, the kicker 11 kicks the materials out from the main conveyor, and the materials roll down the ramp. Because there is already a piece of material on the centering storage device 13, the distributor 12 pushes out and caches multiple materials on the ramp.

[0052] See also Fig. 9 The figure is a schematic diagram of the distribution of the storage module 1 from the elevation, which shows that the storage module 1 distributes materials. When there is no material in the centering storage device 13, the kicker 11 extends to receive the material; the distributor 12 distributes and rolls down the first material in the buffer, and at the same time supports the second material and buffers the remaining materials; after receiving the material, the kicker 11 slowly retracts and receives the material to the centering storage device 13, and then the centering storage device 13 centers and positions the material. At the same time, the distributor 12 is reset.

[0053] 2. Stacker 21 enters the warehouse: After the centering and positioning of the materials in the centering warehouse 13 is completed, the stacker 21 arrives at the warehouse entry position; see Fig.12 This is a cross-sectional view of the fork 23 passing through without a load. The fork 23 extends and extends into the cavity of the centering warehouse 13. The I-shaped V-shaped block 231 on the fork 23 matches with the notch on the upper surface of the centering warehouse 13. Then the cargo platform 22 is slightly lifted, the material is separated from the upper surface of the centering warehouse 13, and the I-shaped V-shaped block 231 supports the material. Fig.11 The fork 23 is loaded through the cross-sectional view, and then the fork 23 is retracted, and the waist of the I-shaped V-shaped block 231 passes through the middle gap of the centering warehouse 13. After the fork 23 is retracted into place, the clamp 24 clamps the material to prevent the cylindrical material 7 from jumping when the stacker 21 moves at high speed.

[0054] 3. Stacker 21 inventory: Stacker 21 runs at high speed to reach the designated storage location of the material; see Fig.11 The fork 23 is a cross-sectional view of the material passing through the fork 23, the fork 23 supports the material to extend, and the waist of the I-shaped V-shaped block 231 passes through the middle gap of the storage rack 31; the I-shaped V-shaped block 231 on the fork 23 matches with the gap on the upper surface of the storage rack 31; then the cargo platform 22 is slightly lowered, the material is separated from the upper surface of the I-shaped V-shaped block 231, and the storage rack 31 supports the material; see Fig.12 The fork 23 is passing through the cross-sectional view without any load, and then the fork 23 is retracted, and the I-shaped V-shaped block 231 passes through the cavity of the storage rack 31. The material has been stored in the designated storage rack 31, and the material storage has been completed.

[0055] 4. The stacker 21 picks up the goods: the storage control module receives the warehouse exit instruction, and controls the stacker 21 in the corresponding subsystem to run to the designated storage position according to the preset warehouse exit rules; the fork 23 extends and extends into the cavity of the designated storage rack 31; the I-shaped V-shaped block 231 on the fork 23 matches the notch on the upper surface of the storage rack 31; then the cargo platform 22 rises slightly, the material is separated from the upper surface of the storage rack 31, and the I-shaped V-shaped block 231 supports the material; then the fork 23 retracts, and the waist of the I-shaped V-shaped block 231 passes through the middle notch of the storage rack 31. After the fork 23 retracts into place, the clamp 24 clamps the material.

[0056] 5. Stacker 21 out of the warehouse: Stacker 21 runs at high speed to the out of the warehouse position; see Fig.13 Schematic diagram of the fork 23 carrying the material out of the warehouse. The fork 23 supports the material to extend, and the waist of the I-shaped V-shaped block 231 passes through the middle gap of the outbound device 41; the I-shaped V-shaped block 231 on the fork 23 is matched with the gap on the upper surface of the outbound device 41; see Fig.14 This is a schematic diagram of the fork 23 unloading and unloading. Then the cargo platform 22 is slightly lowered, and the material is separated from the upper surface of the I-shaped V-shaped block 231. Because the upper surface of the unloading device 41 is at an inclined angle, it pushes the material into the ramp. Then the fork 23 is retracted, and the I-shaped V-shaped block 231 passes through the cavity of the storage rack 31. The fork 23 is retracted into place, and the stacker 21 completes the unloading.

[0057] 6. Buffer out: The outbound device 41 pushes the material into the ramp, and the material rolls along the ramp into the outbound buffer. Fig.15 It is a schematic diagram of the facade cache of the outbound module 4, which shows that the outbound module 4 includes a kicker 11, a distributor 12, and an outbound device 41.

[0058] It shows that the ramp is arranged in height difference, with the high position at the outbound device 41, the middle position at the distributor 12, and the low position at the main conveyor line 5. Under the action of gravity, the cylindrical material 7 rolls from the high position to the low position along the ramp.

[0059] It schematically shows the buffering of materials: the materials roll down along the ramp, and because the main conveyor line 5 is conveying materials, the distributor 12 pushes out to buffer a plurality of materials on the ramp.

[0060] See also Fig.16 This is a schematic diagram of the distribution of materials from the outbound module 4. When there is no material in this section of the main conveyor line 5, the kicker 11 extends to receive the material; the distributor 12 distributes and rolls the first material in the buffer, and at the same time supports the second material and buffers the remaining materials; after receiving the material, the kicker 11 slowly retracts and receives the material to the main conveyor line 5, and the distributor 12 resets at the same time. The outbound is completed.
