Description

Technical Field

[0001] This patent relates to the technical field of logistics equipment, specifically a front-end conveying equipment for a warehouse. Background Art

[0002] Currently, there are usually two types of front-end conveying equipment for automated warehouses: conveyors or ring shuttle vehicles. Conveyors are continuously operating, with high efficiency. However, the number of equipment is large, the overall cost is high, and the commissioning cycle is long. The single equipment of the ring shuttle vehicle has a relatively high running speed, but due to the relatively single path and few scheduling means, the overall efficiency is not high, and it is difficult to improve the efficiency by increasing the number of equipment.

[0003] Taking all these into consideration and combining the characteristics of conveyors and ring shuttle vehicles, it is planned to develop a new type of conveying system that can completely replace ring shuttle vehicles and some more complex conveyor lines. It has the characteristics of high equipment speed, rich scheduling means, low comprehensive cost, and short commissioning cycle. Content of the Utility Model

[0004] In order to solve the above technical problems, this application provides a front-end conveying equipment for a warehouse, and its technical solution is as follows:

[0005] A front-end conveying equipment for a warehouse includes several docking stations, a vehicle body, tracks, and a charging station. The docking stations include a conveyor for loading and unloading docking with a forklift and a conveyor for docking with a stacker. The conveyor is a chain conveyor or a roller conveyor; the tracks provide support and guidance for the vehicle body; the power supply station charges the vehicle body; the tracks are arranged longitudinally in a "day" shape, and the vehicle body is a four-way shuttle vehicle.

[0006] Further, the tracks include a bearing surface, guiding edges, are divided into the X-axis direction and the Y-axis direction, and a reversing port.

[0007] Further, the vehicle body includes an inner frame component, an outer frame component, a conveying component, and an electrical component. The inner frame component and the outer frame component are constrained to move only up and down by guiding components around, and the up and down movement power is provided by a lifting drive component; the conveying component conveys goods in and out of the vehicle body; the electrical component is used to receive instructions from the upper computer and control the actions of the vehicle body; the driving motor drives the X-direction walking wheels and the Y-direction walking wheels to rotate through chain transmission respectively.

[0008] Further, the lifting component is driven by a lifting motor to rotate a crank installed on the inner frame component, which cooperates with a lifting connecting piece installed on the outer frame component to drive the inner frame component to move up and down.

[0009] Further, the inner frame component includes a positioning component. The electric cylinder bracket is fixed on the outside of the inner frame component, and the electric cylinder is fixed on the bracket. Through a connecting sleeve, it is connected to a positioning pin, and the sliding bearing seat guides the positioning pin. When it needs to be fixed, the positioning pin is pushed by the electric cylinder and inserted into the corresponding bracket hole to prevent the vehicle body from slipping.

[0010] Further, the outer frame component includes X-direction traveling wheels and X-direction traveling guide wheels installed on the frame. The diameter of the X-direction traveling wheels is larger than that of the Y-direction traveling wheels. The X-direction traveling guide wheels contact the guide edge and play a guiding role when the vehicle body travels in the X direction.

[0011] Further, the conveying component includes: a conveying motor, a conveying chain. Goods are placed on the chain, and under the drive of the conveying motor, the goods move to complete the docking with the docking station.

[0012] Further, a movable auxiliary bearing seat is installed on the inner frame component, and the movable auxiliary bearing seat moves up and down along with the transmission shaft.

[0013] Further, the electrical components include a PLC, a servo driver, a battery, a photoelectric sensor, and a wireless communication module. After receiving the instructions from the upper computer, the PLC issues instructions to the servo driver to control the vehicle body to execute actions. The battery provides power for the equipment. The obstacle avoidance photoelectric sensors are installed around the vehicle body. The wireless communication module transmits data with the upper computer on the vehicle body.

[0014] Compared with the prior art, the present application has the following beneficial effects: (1) Through the optimized "day" - shaped track and applying the four - way vehicle to the pre - warehouse conveying, flexible scheduling before the warehouse is achieved; (2) Reasonable distribution of the speed and acceleration of the four - way vehicle: A combination of large and small wheels is adopted. Large wheels are used in the long - distance driving direction for high - speed driving, and small wheels are used in the short - distance direction to ensure high acceleration. (3) Automatic commutation: The fork can automatically commutate, freely switching between the X - direction and the Y - direction; (4) Efficient docking: When docking with the conveyor, the speed can be automatically adjusted, and it has an anti - slip function; (5) Precise positioning: Barcode positioning is adopted to accurately control the vehicle body speed and positioning accuracy; (5) Intelligent control: In cooperation with the WMS software, the path is adjusted in real - time to improve the action efficiency; (6) Intelligent obstacle avoidance: The equipment sets an obstacle avoidance function at the software and electronic control levels to prevent collisions, and a buffer is set mechanically to reduce the impact of collisions.

[0022] The technical solution of this patent will be further explained below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the device mainly includes docking stations 1, 2, 3, 4, 7, 8, and 9, vehicle body 5, track 6, and charging station 10. The docking stations are typically chain conveyors or roller conveyors. Stations 1, 2, 3, and 4 are usually for loading and unloading for forklifts, while stations 7, 8, and 9 are usually for docking with stacker cranes; these will not be described further in this document. Vehicle body 5 primarily performs conveying operations. Track 6 provides support and guidance for the vehicle body. Charging station 10 is mainly used to charge vehicle body 5.

[0024] Figure 1 The application scenarios are as follows:

[0025] If a pallet needs to be transported from docking station 1 to docking station 8, the vehicle body 5 first moves to point A, receives the pallet via the conveyor, then travels to point B, and after reaching its destination, it is lifted and reversed, using another set of wheels to travel to point D, and then the pallet is transported to docking station 8 via the conveyor.

[0026] If a circular route is used, the vehicle must pass through B, E, F, G, and H before finally reaching D, and the path is singular, limiting scheduling options. In comparison, this route is significantly superior to the multi-pass route.

[0027] like Figure 2 As shown, track 6 is constructed of sheet metal and provides load-bearing and guiding surfaces for four-way transport. 101 is the X-axis track load-bearing surface, primarily used for supporting the vehicle body 5. 102 is the Y-axis track load-bearing surface, also primarily used for supporting the vehicle body 5, and is at the same height as the X-axis load-bearing surface. 103 is the reversing port, where the vehicle body 5 can switch between X and Y directions. 104 is the X-axis guide edge, providing guidance for the vehicle body 5's movement in the X direction. 105 is the Y-axis guide edge, providing guidance for the vehicle body 5's movement in the Y direction.

[0028] like Figure 3As shown, the vehicle body 5 travels on the track 6 to complete the transport operation. It includes an inner frame component 51, an outer frame component 52, a conveying component 53, and an electrical component 54. The inner frame component 51 and the outer frame component 52 are constrained in their mutual degrees of freedom by surrounding guide components 5101, allowing them to move only up and down. The lifting drive component 5102 provides the power for this vertical movement. The conveying component 53 primarily performs the transporting action of the goods. The electrical component 54 receives commands from the host computer and controls the vehicle body 5 to perform various actions.

[0029] like Figure 4 As shown, the inner frame component 51 mainly includes: a) guide wheel assembly 5101: guides the inner frame component and the outer frame component, ensuring that there is no offset or tilting during vertical movement; b) lifting assembly 5102: driven by lifting motor 5105, which rotates crank 5104 to make the inner frame component 5 move up and down; drive motor 5106 (dual output shaft) drives Y-axis traveling wheel 5103 to rotate through chain transmission, making the vehicle body move; positioning assembly 5108.

[0030] Positioning component 5108, etc. Figure 5 As shown, the electric cylinder bracket 51081 is fixed to the outside of the inner frame component, and the electric cylinder 51082 is fixed to the bracket 51081. It is connected to the positioning pin 51084 via the connecting sleeve 51083. The sliding bearing seat 51085 serves as a guide for the positioning pin. When fixation is required, the positioning pin 51085, pushed by the electric cylinder 51082, inserts into the corresponding bracket hole on the ground, thus fixing the vehicle body 5 and preventing it from slipping.

[0031] Outer frame components such as Figure 6 As shown, the outer frame component 52 includes: a) an X-axis traveling wheel assembly 5201, responsible for X-axis travel, with a diameter larger than the X-axis traveling wheel 5103 to facilitate high-speed travel; b) a lifting connector 5202, which cooperates with the crank 5104 of the inner frame component to allow the inner frame component and the outer frame component to move up and down; c) a frame 5203, the frame of the outer frame component, welded from steel plates; d) a moving auxiliary bearing seat 5204, fixed on the inner frame component, and the bearing seat can move up and down with the drive shaft 5207, serving to reinforce the drive shaft 5207; e) an X-axis traveling guide wheel 5206, fixed on the frame 5203, which serves as a guide when the vehicle body travels in the X-axis direction.

[0032] Conveying component 53, such as Figure 7As shown, the conveying assembly 53 includes: a) a conveyor frame 5301, which is the frame of the conveyor and mainly bears the weight of the goods and fixes the chain bearing seats, etc.; b) a conveyor motor 5302; c) a conveyor chain 5303, which adopts a double-row roller conveyor chain; d) a chain tensioning mechanism 5304, which is mainly used for chain tensioning. The goods are placed on the chain 5303, and under the drive of the conveyor motor 5302, the goods move to complete the docking with the docking station.

[0033] Electrical components 54 and PLC 5401, after receiving instructions from the host computer, send commands to the control servo driver 5402 to control the vehicle body 5 to perform actions. Battery 5403 provides power to the equipment. Obstacle avoidance photoelectric sensors 5404 are distributed around the vehicle body to detect the surrounding environment and prevent collisions. Wireless communication module 5405 is responsible for data transmission with the host computer.
