Description

Technical Field

[0001] The utility model relates to a multi-station tray type planar conveying device, belonging to the technical field of inbound and outbound connection equipment in the field of dense library tray racks. Background Technique

[0002] In the prior art, shuttle cars are commonly used in logistics dense libraries. For most enterprises in actual use, the single capacity of the dense library is relatively small, so as to improve the overall loading capacity. This means that the turnover inside the library needs to be very intensive. In order to improve the turnover efficiency, the general current practices are to increase the number of shuttle cars, improve the flexibility of shuttle cars, increase the speed of shuttle cars, reduce the dispatching time of shuttle cars, etc. However, when the number of shuttle cars reaches a certain level, the turnover efficiency in the dense library reaches an upper limit. At this time, increasing the number of shuttle cars will instead result in a decrease in the overall turnover efficiency of the dense library.

[0003] Therefore, the inventor found that there are at least the following problems in the prior art: Without improving the unit loading capacity of the shuttle car, for the turnover efficiency of any actual dense library, there is an optimal upper limit number of shuttle cars. More shuttle cars will only lead to more congestion and reduce the turnover efficiency; on the other hand, the shuttle car needs flexible loading and unloading. The method of simply increasing the loading capacity by increasing the space has the problem of inconvenient unloading. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a multi-station tray type planar conveying device. Through reasonable multi-station and supporting structure arrangements, the multi-station tray type planar conveying device can effectively increase the loading quantity of a single shuttle car, and effectively ensure flexible loading and unloading, avoiding the problem of inconvenient unloading.

[0005] The utility model is achieved through the following technical solutions.

[0006] A multi-station tray type planar conveying device provided by the utility model includes a traveling mechanism; there are a first station at the front part and a second station at the rear part on the traveling mechanism. A first chain conveyor is horizontally installed at the first station, and a second chain conveyor is horizontally installed at the second station. A first telescopic positioning mechanism assembly is installed at the front end of the first station, and a second telescopic positioning mechanism assembly is installed at the front end of the second station and the second telescopic positioning mechanism assembly is located between the first station and the second station. An electric control cabinet is installed at the rear end of the second station for connecting and controlling the first telescopic positioning mechanism assembly, the first chain conveyor, the second telescopic positioning mechanism assembly and the second chain conveyor; A palletizing and depalletizing mechanism assembly is installed at a position in the middle of the first chain conveyor in the first station; the traveling mechanism is a six-wheel structure, and the second telescopic positioning mechanism assembly is directly above the middle wheel of the traveling mechanism; Polyurethane buffers are installed at both the front and rear ends of the bottom of the traveling mechanism for anti-collision buffering.

[0007] A first top cover plate is fixed on the first working station. The top surface height of the first top cover plate is lower than the top surface height of the chain of the first chain conveyor, but higher than the top surface height of the support of the first chain conveyor.

[0008] A second top cover plate is fixed on the second working station. The top surface height of the second top cover plate is lower than the top surface height of the chain of the second chain conveyor, but higher than the top surface height of the support of the second chain conveyor.

[0009] The unstacking and stacking mechanism assembly is installed through the unstacking and stacking mechanism mounting frame, and the unstacking and stacking mechanism mounting frame is fixed to the traveling mechanism.

[0010] The feet of the first chain conveyor and the second chain conveyor are fixed to the traveling mechanism through bottom hexagon bolts; the electric control cabinet is fixed to the traveling mechanism through hexagon head bolts.

[0013] A plurality of detachable lifting eye bolts are fixed on the first working station and the second working station for hoisting. The top end height of the lifting eye bolts is higher than the top surface height of the first chain conveyor and the second chain conveyor.

[0014] The beneficial effects of the present utility model are as follows: Through reasonable multi-station and supporting structure arrangements, the loading quantity of a single shuttle car can be effectively increased.

Specific implementation mode

[0018] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0019] The first implementation mode of the present invention relates to a multi-station pallet-type planar conveying device as shown in Figure 1 , Figure 2 , which includes a traveling mechanism 2; there are a first station at the front and a second station at the rear on the traveling mechanism 2. A first chain conveyor 3 is horizontally installed at the first station, a second chain conveyor 11 is horizontally installed at 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 in the middle of the first station and the second station. 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; An unstacking and palletizing mechanism assembly 5 is installed at the position in the middle of the first chain conveyor 3 in the first station; Further, the traveling mechanism 2 is a six-wheel structure, and the second telescopic positioning mechanism assembly 7 is directly above the middle wheel of the traveling mechanism 2; Polyurethane buffers 17 are installed at both the front and rear ends of the bottom of the traveling mechanism 2 for anti-collision buffering.

[0020] Thus, the first station and the second station can operate relatively independently in the loading and unloading operations, thereby ensuring flexible loading and unloading, and the loading and unloading of one station will not affect the loading and unloading operations of the other station at all; In terms of transportation, it is completed by a set of traveling mechanism 2, occupying a small space and not causing more congestion risks due to more loading capacity; Generally speaking, it is also easy to be obtained by modifying the existing shuttle car, and the market promotion cost is low.

[0021] The second implementation mode of the present invention is substantially the same as the first implementation mode, mainly in that a first top cover plate 6 is fixed on the first station, and the top surface height of the first top cover plate 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.

[0022] Further, a second top cover plate 12 is fixed on the second 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.

[0023] Further, the first top mask 6 is fixed to the first telescopic positioning mechanism assembly 1 and the second telescopic positioning mechanism assembly 7 by edge hexagon bolts 18.

[0024] Further, the second top mask 12 is fixed to the second telescopic positioning mechanism assembly 7 and the electric control cabinet 15 by edge hexagon bolts 18.

[0025] Further, the feet 14 of the first chain conveyor 3 and the second chain conveyor 11 are both fixed to the traveling mechanism 2 by bottom hexagon bolts 8; further, the electric control cabinet 15 is fixed to the traveling mechanism 2 by hexagon head bolts 16.

[0026] Further, the palletizing and depalletizing mechanism assembly 5 is installed through the palletizing and depalletizing mechanism mounting bracket 4, and the palletizing and depalletizing mechanism mounting bracket 4 is fixed to the traveling mechanism 2.

[0027] Further, a plurality of detachable lifting eye bolts 13 are fixed on the first working station and the second working station for hoisting, and the top height of the lifting eye bolts 13 is higher than the top surface height of the first chain conveyor 3 and the second chain conveyor 11. Generally, during formal operation, the lifting eye bolts 13 need to be removed, and the lifting eye bolts 13 are only installed when transfer is required to facilitate hoisting.

[0028] 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 forks, there are forklift holes on the corresponding logistics pallets, and the palletizing and depalletizing mechanism assembly 5 has a motor and a lifting mechanism.

[0029] In the above embodiments, in addition to loading and unloading goods, the palletizing and depalletizing mechanism assembly can also provide functions of palletizing and depalletizing pallets, where:

[0030] The typical working process of palletizing is as follows: After the first pallet is transported to the first working station, the motor of the palletizing and depalletizing mechanism rotates to lift the pallet by the height of one pallet thickness. The motors of the two telescopic positioning mechanisms run simultaneously to drive the two groups of forks to extend. The forks extend into the forklift holes of the pallet, and then the first pallet is lifted. The motor of the palletizing and depalletizing mechanism continues to rotate, and the support frame descends. The second pallet is then continuously conveyed. The telescopic positioning mechanism reverses, and the forks retract. 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.

[0031] The typical working process of pallet de-stacking is as follows: The pallet stack is conveyed by a chain conveyor to stop at the first station. The motor of the palletizing and de-palletizing mechanism rotates, and the support frame lifts the pallet stack and then stops. Then the motors of the two telescopic positioning mechanisms rotate, driving the fork bodies to extend into the forklift holes of the second pallet from the bottom upwards, and holding the second and subsequent pallets. Then the motor of the palletizing and de-palletizing mechanism continues to rotate, and the support frame lowers the first pallet onto the chain conveyor. Then, the chain conveyor operates to convey the first pallet out, completing the de-stacking process of the first pallet. The motor of the palletizing and de-palletizing mechanism continues to rotate, lifting the support frame to the highest point to support the second pallet. The two telescopic positioning mechanisms reverse simultaneously, driving the fork bodies to retract. Then the motor of the palletizing and de-palletizing mechanism continues to rotate, lowering the remaining pallet stack onto the chain conveyor, and repeating this process to complete the de-stacking function of one pallet stack.

[0032] After actual testing, when the dense storage of a certain logistics enterprise used the original single shuttle cars, there were 100 shuttle cars, and three-way in-and-out warehouse channels, with a cargo turnover volume of about 3,000 pieces per hour. Subsequently, the number of shuttle cars was increased to 150, and the cargo turnover volume per hour was about 3,300 pieces. After the number of shuttle cars was increased to 200, it was found that the cargo turnover volume per hour 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 modifying 50 of them to the solution of the above-mentioned embodiment of the present utility model, the cargo turnover volume per hour was about 3,800 pieces.
