Description

Technical Field

[0001] This utility model relates to a novel material box guiding and limiting device and an AGV using the device, belonging to the field of logistics warehousing and automation control. Background Technology

[0002] Currently, various handling devices, such as unmanned automated guided vehicles (AGVs), are widely used in logistics warehousing and automated production sites to carry and transport various material boxes to designated workstations.

[0003] In the current AGV (Automated Guided Vehicle) automated loading and unloading of material boxes, the boxes are prone to displacement due to inaccurate positioning or vibration. Without appropriate protective measures, this not only compromises the stability and efficiency of box transport but may also lead to box tipping or falling, affecting the on-site working environment and personnel safety. Furthermore, existing limit devices are overly complex, with high installation and maintenance costs, making it difficult to achieve seamless integration and automated operation control with AGVs in high-load and high-speed logistics transfers.

[0004] In view of the above, this patent application is hereby filed. Utility Model Content

[0005] The material box guiding and limiting device and the AGV using the device described in this application aim to solve the problems existing in the prior art by proposing a passive reset mechanism based on an L-shaped baffle and an elastic component, so as to achieve automatic guidance and elastic limiting of the material box, thereby achieving the purpose of convenient operation, improved stability and automated operation efficiency.

[0006] To achieve the above design objectives, the material box guide and limiting device includes a base plate, two sets of fixed seats vertically fixed on the base, the bent part of the L-shaped baffle is horizontally hinged between the two sets of fixed seats, and two sets of springs are respectively connected between one set of fixed seats and the L-shaped baffle.

[0007] Furthermore, the bent portion of the L-shaped baffle is fixedly connected to a rotating shaft in the horizontal direction, and two sets of bushings are respectively set on the two sets of fixed seats, with the two ends of the rotating shaft respectively connected to the bushings.

[0008] Furthermore, a set of baffles is provided on both sides of the vertical part of the L-shaped baffle, and a set of positioning blocks is provided on the fixed base; when the spring retracts and pulls the L-shaped baffle to flip outward, the baffle presses down against the positioning block.

[0009] Furthermore, the L-shaped baffle remains tilted under the action of the spring, with the tilt angle between 15° and 30°.

[0010] Based on the aforementioned bin guiding and limiting device, this application proposes a new AGV, on which the aforementioned bin guiding and limiting device is installed on the top of the AGV.

[0011] As described above, the bin guiding and limiting device and the AGV using the device described in this application have the following advantages:

[0012] 1. This application adopts a passive elastic reset mechanism, which has the characteristics of simple and compact structure and easy installation and maintenance.

[0013] 2. This application achieves seamless integration with AGV, significantly improving the level of automation without the need for manual intervention.

[0014] 3. This application has high stability and can effectively prevent the material box from shifting and falling during the movement of the AGV, thereby improving the stability and safety of the on-site conveying system. Attached Figure Description

[0018] Figures 4-1 to 4-2 This is a schematic diagram illustrating the guiding and positioning process of placing the material bin on the AGV; Detailed Implementation

[0019] Example 1, such as Figures 1 to 3 As shown, this application proposes a novel material box guiding and limiting device. The device includes a base plate 1, two sets of fixing seats 2 which are vertically fixed to the base 1 by two sets of internal hexagonal screws 3 respectively, the bent part of the L-shaped baffle 5 is horizontally hinged between the two sets of fixing seats 2, and two sets of springs 4 are respectively connected between the one set of fixing seats 2 and the L-shaped baffle 5.

[0020] Among them, the bent part of the L-shaped baffle 5 is fixedly connected to the rotating shaft 501 in the horizontal direction, and two sets of bushings 201 are respectively set on the two sets of fixed seats 2, and the two ends of the rotating shaft 501 are respectively connected to the bushings 201.

[0021] A set of baffles 502 is provided on both sides of the vertical part of the L-shaped baffle 5, and a set of positioning blocks 202 is provided on the fixed base 2. When the spring 4 retracts and pulls the L-shaped baffle 5 to flip outward, the baffle 502 presses against the positioning block 202 downward.

[0022] In the initial state, the L-shaped baffle 5 is kept tilted under the action of the spring 4, with the tilt angle between 15° and 30°, to facilitate the guidance of the material box 20 when it is lowered. Accordingly, the stiffness and length of the spring 4 can be designed to match the weight and size of the material box 20.

[0023] As described above, the bottom plate 1 of the hopper guide and limiting device can be installed and connected to the top of the AGV 10. When the AGV 10 needs to carry or transfer the hopper 20, the hopper 20 can be placed vertically above the bottom plate 1 using a lifting device (such as a forklift). The bottom of the hopper 20 simultaneously contacts the L-shaped baffle 3 in its initial state. At this time, the two sets of L-shaped baffles 3 on both sides tilt outwards respectively, and the hopper 20 slides and descends along the inclined surface. The two sets of L-shaped baffles 3 are pressed down by the hopper 20 until the hopper 20 is completely placed in position and the L-shaped baffle 3 stretches the spring 4 to its maximum stroke. The L-shaped baffles 3 and spring 4 on both sides guide the hopper 20 through the inclined surface, causing it to automatically center itself.

[0024] After the material box 20 is placed in place, its own weight presses the L-shaped baffle 3 down to a vertical position, thereby limiting the material box 20. The material box 20 is fixed in the horizontal direction, which can effectively prevent it from shifting due to vibration or external force.

[0025] After the AGV transports the material box 20 to the designated workstation, the lifting device vertically lifts and removes the material box 20. The L-shaped baffle 3 loses the pressure of the weight of the material box 20 and flips outward under the action of the spring 4. At this time, the baffle 502 presses down against the positioning block 202, the L-shaped baffle 5 is braked and stopped, and returns to the initial tilted state.

[0026] Through the detailed description of the above embodiments, the present invention achieves automatic guidance and limiting of the material box 20 through the design of a simple L-shaped baffle 5, reducing the risk of deviation and falling during transportation.

[0027] Based on the innovative structural design of the aforementioned bin guiding and limiting device, this application proposes to apply the aforementioned bin guiding and limiting device to AGV10, by installing the aforementioned bin guiding and limiting device on the top of AGV10.

[0028] As described above, through the detailed description of the above embodiments, this application achieves automatic guidance and limiting of the material box through the L-shaped baffle design. It is convenient to operate, safe and reliable, and effectively reduces the risk of the material box shifting and falling during transportation. It has significant economic benefits and industry promotion value.
