[0002] The four-way vehicle stereoscopic warehouse is a high-density intelligent shelf storage system composed of warehouse shelves, four-way vehicles, tracks and control systems, which can realize fully automated operations. Most of the four-way vehicle stereoscopic warehouses in related technologies are renovated from old factories. The original site is narrow and long, and the height is low. Affected by the original site layout and production lines, the distribution path of the four-way vehicle stereoscopic warehouse is too long, the distribution time of the four-way vehicle is too long, and the single vehicle distribution efficiency has a certain upper limit. Summary of the invention

[0003] In view of this, the present invention provides a stereoscopic warehouse, a four-way vehicle stereoscopic warehouse system and a distribution method thereof, so as to solve the problem of low distribution efficiency of four-way vehicles in a four-way vehicle stereoscopic warehouse in the related art.

[0004] In a first aspect, the present invention provides a three-dimensional warehouse, comprising:

[0005] The storage locations are arranged in multiple intervals along the length direction;

[0006] Sub-tracks are set at both ends of each inventory location;

[0007] The main track includes a first track segment, a second track segment and a middle section conveying line, wherein the middle section conveying line connects the first track segment and the second track segment, and the main track is located on one side of the length direction of the plurality of inventory locations.

[0008] Beneficial effect: Since the main track includes the first track section, the second track section and the middle conveyor line, the middle conveyor line connects the first track section and the second track section, and the middle conveyor line divides the stereoscopic warehouse into a left half warehouse and a right half warehouse located at both ends of the length direction of the middle conveyor line. Four-way vehicles can be set in the left half warehouse and the right half warehouse respectively. When the distribution rhythm requirement is high, the middle conveyor line only transports the goods. When the goods are put into storage, the four-way vehicle located in the left half warehouse is responsible for delivering the goods to the inventory position of the left half warehouse and transferring the goods to the middle conveyor line. After the four-way vehicle transfers the goods to the middle conveyor line, it can return to continue the distribution work. The four-way vehicle located in the right half warehouse connects the goods transported from the middle conveyor line and delivers the goods to the inventory position of the right half warehouse. When the goods are shipped out, the goods in the right half of the warehouse are delivered to the elevator by the four-way vehicle, and the elevator changes the level of the goods and moves them to the designated exit. The goods in the left half of the warehouse are delivered to the middle conveyor line by the four-way vehicle, and then the four-way vehicle in the right half of the warehouse connects and delivers them, and the four-way vehicle in the left half of the warehouse returns to continue delivery. Therefore, the delivery cycle efficiency can be improved and the efficiency can be avoided from being affected by the long delivery distance of the four-way vehicle.

[0009] In an optional embodiment, the inventory locations are provided on both sides of the main track.

[0010] Beneficial effects: There are inventory locations on both sides of the main track, so there are sub-tracks on both sides of the main track. Each sub-track is connected to the main track. When the goods are put into the warehouse, the four-way vehicle first moves along the main track, moves to the position corresponding to the target inventory location, and then moves along the sub-track to the target inventory location. When the goods are taken out of the warehouse, the four-way vehicle moves along the sub-track to the main track with the goods, and then moves along the main track. By setting up inventory locations on both sides of the main track, the length of each sub-track can be relatively reduced, and the distribution efficiency can be improved.

The second four-way vehicle located in the right half of the warehouse connects with the goods transported from the middle conveyor line and delivers the goods to the inventory position of the right half of the warehouse. When the goods leave the warehouse, the goods in the right half of the warehouse are delivered to the second elevator by the second four-way vehicle. The second elevator changes the level of the goods and moves to the designated exit. The goods in the left half of the warehouse are delivered to the middle conveyor line by the first four-way vehicle, and then connected and delivered by the second four-way vehicle in the right half of the warehouse. The first four-way vehicle in the left half of the warehouse returns to continue delivery. Therefore, the efficiency of the delivery rhythm can be improved, and the efficiency can be avoided from being affected by the long delivery distance of the four-way vehicle.

[0018] In an optional embodiment, the four-way vehicle stereoscopic warehouse system further includes an incoming conveyor line and an outgoing conveyor line, wherein the incoming conveyor line is connected to the first elevator, and the outgoing conveyor line is connected to the second elevator.

[0019] Beneficial effect: By setting up the incoming conveyor line and the outgoing conveyor line, the incoming conveyor line is connected to the first elevator, and the outgoing conveyor line is connected to the second elevator. When the goods are put into the warehouse, the incoming conveyor line transports the goods to the first elevator, and the first elevator lifts the goods to the target floor.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0046] The four-way vehicle stereoscopic warehouse is a high-density intelligent shelf storage system composed of warehouse shelves, four-way vehicles, tracks and control systems, which can realize fully automated operations. Most of the four-way vehicle stereoscopic warehouses in related technologies are renovated from old factories. The original site is narrow and long, and the height is low. Affected by the original site layout and production lines, the distribution path of the four-way vehicle stereoscopic warehouse is too long, the distribution time of the four-way vehicle is too long, and the single vehicle distribution efficiency has a certain upper limit.

[0047] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a three-dimensional warehouse is provided, comprising: a storage location 1, a sub-track 2 and a main track.

[0049] Among them, multiple inventory locations 1 are arranged at intervals along the length direction; sub-tracks 2 are arranged at both ends of each inventory location 1; the main track includes a first track segment 3, a second track segment 4 and a middle section conveyor line 5, the middle section conveyor line 5 connects the first track segment 3 and the second track segment 4, and the main track is located on one side of the length direction of multiple inventory locations 1.

[0050] In this embodiment, since the main track includes the first track section 3, the second track section 4 and the middle conveyor line 5, the middle conveyor line 5 connects the first track section 3 and the second track section 4, and the middle conveyor line 5 divides the stereoscopic warehouse into a left half warehouse and a right half warehouse located at both ends of the middle conveyor line 5 in the length direction. Four-way vehicles can be set in the left half warehouse and the right half warehouse respectively. When the distribution rhythm requirement is high, the middle conveyor line 5 only transports the goods. When the goods are put into storage, the four-way vehicle located in the left half warehouse is responsible for delivering the goods to the inventory position 1 of the left half warehouse and transferring the goods to the middle conveyor line 5. After the four-way vehicle transfers the goods to the middle conveyor line 5, it can return to continue the distribution work. The four-way vehicle located in the right half warehouse connects the goods transported from the middle conveyor line 5 and delivers the goods to the inventory position 1 of the right half warehouse. When the goods are shipped out, the goods in the right half of the warehouse are delivered to the elevator by the four-way vehicle, and the elevator changes the level of the goods and moves them to the designated exit. The goods in the left half of the warehouse are delivered to the middle conveyor line 5 by the four-way vehicle, and then the four-way vehicle in the right half of the warehouse connects and delivers them, and the four-way vehicle in the left half of the warehouse returns to continue delivery. Therefore, the delivery cycle efficiency can be improved, and the efficiency can be avoided from being affected by the long delivery distance of the four-way vehicle.

[0051] It should be noted that the three-dimensional warehouse includes multiple layers, and each layer is provided with a main track and a sub-track 2.

[0052] It should be noted that the four-way car is also called a pallet four-way shuttle car, which generally uses two sets of wheel systems: one set is responsible for operation in the X direction, and the other set is responsible for operation in the Y direction. In the turning link, the turning is completed by exchanging the wheel system (height difference), and the pallet itself does not turn. The shuttle car uses a lifting mechanism to pick up and put down goods. When picking up goods, the shuttle car enters under the pallet, aligns with the rear lifting mechanism to rise, and lifts the pallet, leaving the bottom of the shelf L-beam or the conveyor chain surface. At this time, the shuttle car and the pallet can run away from the shelf; in the delivery link, after the shuttle car moves the pallet to the designated cargo position, it aligns with the rear lifting mechanism to descend, and the pallet will be placed on the L-beam or conveyor, so that the shuttle car completes a delivery operation.

[0053] In one embodiment, storage locations 1 are provided on both sides of the main track.

[0054] In this embodiment, both sides of the main track are provided with storage locations 1, so both sides of the main track are provided with sub-tracks 2, and each sub-track 2 is connected to the main track. When goods are put into storage, the four-way vehicle first moves along the main track, moves to the position corresponding to the target storage location 1, and then moves along the sub-track 2 to the target storage location 1. When goods are taken out of the warehouse, the four-way vehicle moves along the sub-track 2 to the main track with the goods, and then moves along the main track. By providing storage locations 1 on both sides of the main track, the length of each sub-track 2 can be relatively reduced, thereby improving the distribution efficiency.

[0055] According to an embodiment of the present invention, in a second aspect, a four-way vehicle stereoscopic warehouse system is provided, comprising: the stereoscopic warehouse provided in the above embodiment, a first four-way vehicle, a second four-way vehicle, a first elevator 6 and a second elevator 7.

[0057] In this embodiment, when the delivery rhythm requirement is high, the middle conveyor line 5 only transports the goods. When the goods are put into storage, the first four-way vehicle located in the left half warehouse is responsible for delivering the goods to the inventory position 1 of the left half warehouse and transferring the goods to the middle conveyor line 5. After the first four-way vehicle transfers the goods to the middle conveyor line 5, it can return to continue the delivery work. The second four-way vehicle located in the right half warehouse connects with the goods transported from the middle conveyor line 5 and delivers the goods to the inventory position 1 of the right half warehouse. When the goods are out of the warehouse, the goods located in the right half warehouse are delivered to the second elevator 7 by the second four-way vehicle. The second elevator 7 changes the level of the goods and moves to the designated exit. The goods located in the left half warehouse are delivered to the middle conveyor line 5 by the first four-way vehicle, and then the second four-way vehicle in the right half warehouse connects and delivers them. The first four-way vehicle in the left half warehouse returns to continue the delivery. Therefore, the delivery rhythm efficiency can be improved, and the efficiency is not affected by the long delivery distance of the four-way vehicle.
