Description

Technical Field

[0001] The invention relates to a disassembling and stacking disc type double-station shuttle vehicle, belonging to the technical field of in-and-out warehouse connection equipment in the field of intensive warehouse pallet racks. Background Art

[0002] Shuttle vehicles are often used in logistics intensive warehouses in the existing technology. For most companies that actually use them, the single capacity of the intensive warehouse is relatively small, in order to increase the overall loading volume, which means that the turnover within the warehouse needs to be very intensive. In order to improve the turnover efficiency, the general practice is to increase the number of shuttle vehicles, improve the flexibility of shuttle vehicles, increase the speed of shuttle vehicles, reduce the deployment time of shuttle vehicles, etc. However, when the number of shuttle vehicles reaches a certain level, the turnover efficiency in the intensive warehouse reaches an upper limit. At this time, increasing the number of shuttle vehicles will result in a decrease in the overall turnover efficiency of the intensive warehouse.

[0003] Therefore, the inventors discovered that there are at least the following problems in the prior art: without increasing the unit loading capacity of the shuttle carts, there is an optimal upper limit number of shuttle carts for the turnover efficiency of any actual dense warehouse, and more shuttle carts will only cause more congestion and reduce turnover efficiency; on the other hand, the shuttle carts require flexible loading and unloading, and the method of simply increasing the loading capacity by increasing the space will cause the problem of inconvenience in unloading. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a double-station shuttle with a detachable disc. The double-station shuttle with a detachable disc can effectively increase the loading quantity of a single shuttle through a reasonable arrangement of multiple stations and supporting structures, and effectively ensure flexible loading and unloading, avoiding the problem of inconvenience in unloading.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0021] A first embodiment of the present invention relates to Figure 1 , Figure 2 A palletizing and stacking disc type double-station shuttle vehicle shown in the figure comprises a traveling mechanism 2; the traveling mechanism 2 has a first station at the front and a second station at the rear, a first chain conveyor 3 is transversely installed on the first station, and a second chain conveyor 11 is transversely installed on the second station, a first telescopic positioning mechanism assembly 1 is installed at the front end of the first station, a second telescopic positioning mechanism assembly 7 is installed at the front end of the second station and the second telescopic positioning mechanism assembly 7 is located between the first station and the second station, and an electric control cabinet 15 is installed at the rear end of the second station for connecting and controlling the first telescopic positioning mechanism assembly 1, the first chain conveyor 3, the second telescopic positioning mechanism assembly 7 and the second chain conveyor 11; a palletizing and stacking mechanism assembly 5 is installed at a position located in the middle of the first chain conveyor 3 in the first station.

[0022] As a result, the first workstation and the second workstation can operate relatively independently in loading and unloading operations, thereby ensuring flexible loading and unloading, and the loading and unloading of one workstation will not affect the loading and unloading operations of the other workstation at all; and in terms of transportation, it is completed through a set of walking mechanisms 2, which occupies a small space and will not cause more congestion risks due to more loading volume; overall, it is also easy to obtain by modifying the existing shuttle car, and the marketing cost is low.

[0023] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that a first top panel 6 is fixed on the first station, and the top surface height of the first top panel 6 is lower than the top surface height of the chain of the first chain conveyor 3, but higher than the top surface height of the bracket of the first chain conveyor 3.

[0024] Furthermore, a second top cover plate 12 is fixed on the second work station, and the top surface height of the second top cover plate 12 is lower than the top surface height of the chain of the second chain conveyor 11 , but higher than the top surface height of the bracket of the second chain conveyor 11 .

[0025] Furthermore, the first top panel 6 is fixed to the first telescopic positioning mechanism assembly 1 and the second telescopic positioning mechanism assembly 7 by means of hexagonal bolts 18 .

[0026] Furthermore, the second top panel 12 is fixed to the second telescopic positioning mechanism assembly 7 and the electric control cabinet 15 by means of hexagonal bolts 18 .

[0027] Furthermore, the machine feet 14 of the first chain conveyor 3 and the second chain conveyor 11 are both fixed to the traveling mechanism 2 by means of bottom hexagonal bolts 8 ; further, the electric control cabinet 15 is fixed to the traveling mechanism 2 by means of hexagonal head bolts 16 .

[0028] The third embodiment of the present invention is substantially the same as the first embodiment, mainly in that the palletizing and disassembling mechanism assembly 5 is installed via the palletizing and disassembling mechanism mounting frame 4 , and the palletizing and disassembling mechanism mounting frame 4 is fixed to the traveling mechanism 2 .

[0029] Furthermore, the traveling mechanism 2 is a six-wheel structure, and the second telescopic positioning mechanism assembly 7 is located directly above the middle wheel of the traveling mechanism 2 .

[0030] Furthermore, polyurethane buffers 17 are installed at the front and rear ends of the bottom of the walking mechanism 2 for anti-collision and buffering.

[0031] Furthermore, a plurality of detachable eyebolts 13 are fixed on the first station and the second station for hoisting, and the top height of the eyebolts 13 is higher than the top surface height of the first chain conveyor 3 and the second chain conveyor 11. Generally, the eyebolts 13 need to be removed during formal operation, and the eyebolts 13 are installed only when transportation is required to facilitate hoisting.

[0032] Similar to the general scheme of the prior art, the first telescopic positioning mechanism assembly 1 and the second telescopic positioning mechanism assembly 7 are equipped with motors and fork bodies, and the corresponding logistics pallets are provided with forklift holes, and the stacking and disassembling mechanism assembly 5 has a motor and a lifting mechanism.

[0033] In addition to loading and unloading, the above-mentioned embodiment can also provide pallet stacking and disassembling functions based on the palletizing and disassembling mechanism assembly, wherein:

[0034] The typical working process of pallet chopping is as follows: after the first pallet is transferred to the first station, the motor of the pallet removal mechanism rotates to lift the pallet to a height of one pallet thickness, and the motors of the two telescopic positioning mechanisms run at the same time, driving the two sets of forks to extend, and the forks are inserted into the forklift holes of the pallet. Then, the first pallet is lifted, the motor of the pallet removal mechanism continues to rotate, the support frame falls, and the second pallet continues to be transported over. The telescopic positioning mechanism reverses, the forks retract, and the first pallet is placed on the second pallet. In this way, the first stacking is completed, and this process is repeated to complete the stacking function of a stack of pallets.

[0035] The typical working process of depalletizing is as follows: the pallet stack is transported to the first workstation by the chain conveyor and stops. The motor of the depalletizing mechanism rotates, and the support frame lifts the pallet stack and stops. Then the motors of the two telescopic positioning mechanisms rotate, driving the fork body to extend into the forklift hole of the second pallet from the bottom to the top, and hold the second and above pallets. Then the motor of the depalletizing mechanism continues to rotate, and the support frame puts down the first pallet and drops it on the chain conveyor. Then, the chain conveyor runs to transport the first pallet out, completing the depalletizing process of the first pallet. The motor of the depalletizing mechanism continues to rotate, lifting the support frame to the highest point to support the second pallet. The two telescopic positioning mechanisms reverse at the same time, driving the fork body to retract, and then the motor of the depalletizing mechanism continues to rotate, dropping the remaining pallets onto the chain conveyor. This process is repeated to complete the depalletizing function of a pallet.

[0036] After actual testing, a logistics company's dense warehouse used the original single shuttle car, with 100 shuttle cars and three in-and-out channels, with an hourly cargo turnover of about 3,000 pieces. Later, the number of shuttle cars was increased to 150, with an hourly cargo turnover of about 3,300 pieces. After the number of shuttle cars was increased to 200, it was found that the hourly cargo turnover dropped to about 2,400 pieces. After observation, there was a relatively common congestion and waiting phenomenon at this time. After retaining 150 shuttle cars and converting 50 of them into the solution of the above-mentioned implementation mode of the present invention, the hourly cargo turnover was about 3,800 pieces.
