Description

Technical Field

[0001] This utility model relates to the field of material rack positioning technology, and in particular to a material rack positioning and guiding device for transportation. Background Technology

[0002] In non-automated or semi-automated scenarios, material racks are manually pushed or moved by forklifts for docking. This method is not only labor-intensive and inefficient, but also relies entirely on the operator's experience and visual inspection, making it prone to positioning errors. Without effective guidance, forced docking generates enormous lateral and impact forces. Over time, this can damage the positioning elements on the racks and ground equipment, as well as cause hidden damage to the AGV's drive system and precision conveyor rollers, increasing equipment failure rates and maintenance costs. Therefore, a material rack positioning and guiding device needs to be designed.

[0003] To address this, patent CN206900971U discloses a positioning and guiding device for transport racks. The device includes: a base plate with multiple sets of mounting holes corresponding to various sizes of transport racks; multiple positioning guide blocks, movably mounted on the base plate via connections to different sets of mounting holes, to define areas on the base plate for positioning transport racks of different sizes; and multiple sets of height positioning blocks, each corresponding to a different size of transport rack, with each set of height positioning blocks mounted on the base plate to position the transport rack in a direction perpendicular to the base plate. The transport rack includes: a body and at least one positioning plane disposed on the body for connecting to at least one height positioning block of the positioning and guiding device. This invention allows for flexible adjustment of the positioning position according to the dimensions of transport racks for different automotive parts, offering high applicability and low modification costs.

[0004] Although the aforementioned material rack positioning and guiding device can facilitate positioning during use, the collision structure between the material rack and the guide frame during transportation will affect the trajectory of the material rack. Therefore, it is necessary to design a material rack positioning and guiding device. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning and guiding device for transport racks, so as to solve the defect of existing transport rack positioning and guiding devices where the rack collides with the guide frame during the transport process, which affects the travel trajectory of the rack.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a positioning and guiding device for a transport rack, including a conveyor;

[0007] The top of the conveyor is provided with adjustment structures on both sides, and the top of each adjustment structure is fixed with a guide frame. The top of the conveyor is provided with a material rack body.

[0008] The inner wall of the guide frame is uniformly provided with a rolling structure, which includes a round shaft, a connecting shaft and a protective strip. The round shaft is uniformly provided on the inner side of the guide frame, and a connecting shaft is fixed at both ends of the round shaft. A protective strip is uniformly fixed on the outer wall of the round shaft.

[0009] Positioning structures are fixed on both sides of the top of the guide frame.

[0010] Furthermore, the adjustment structure includes a mounting plate, an adjustment groove, a lead screw, a drive motor, a support plate, and movable blocks. The mounting plates are all fixed to both sides of the top of the conveyor. An adjustment groove is provided in the middle of the interior of each mounting plate. Movable blocks are provided inside each adjustment groove. Lead screws are threaded into the interior of each movable block. A support plate is fixed to the top of each movable block. The drive motor is fixed to the outer wall of one side of the mounting plate.

[0011] Furthermore, one end of each lead screw extends to the outside of the mounting plate and is fixedly connected to the output end of the drive motor.

[0012] Furthermore, the other end of the lead screw extends into the interior of the mounting plate and is rotatably connected to the mounting plate.

[0013] Furthermore, the guide frames are symmetrically distributed on both sides of the conveyor, and the top view cross-section of one end of the guide frame is arc-shaped.

[0014] Furthermore, the circular shafts are evenly distributed on the inner side of the guide frame, and the ends of the connecting shafts away from the circular shafts extend into the interior of the guide frame and are rotatably connected to the guide frame.

[0015] Furthermore, the positioning structure includes a mounting frame, a positioning plate, a positioner, and a return spring. The mounting frame is fixed to one side of the top of the guide frame. A positioning plate is hinged to one side of the mounting frame. A positioner is fixed to the side of the positioning plate near the material rack body. A return spring is fixed to the side of the positioning plate away from the material rack body.

[0016] Furthermore, the positioning plates are symmetrically distributed on both sides of the conveyor, and the end of the return spring away from the positioning plate is fixedly connected to one side of the mounting frame.

[0017] The advantages of the positioning and guiding device for the transport rack provided by this utility model are as follows:

[0018] By incorporating a rolling structure, when the rack body enters the guide channel, its side contacts the guide frame. Traditional fixed guide plates generate significant sliding friction resistance, which not only hinders the rack body's movement but also causes severe wear on the equipment and the rack body. However, the round shaft and protective strip in the rolling structure roll along with the rack body upon contact, transforming harmful sliding friction into low-resistance rolling friction. This greatly reduces the resistance to the rack body's forward movement, ensuring it can be smoothly and easily guided to the center position. This avoids rack deformation and cargo overturning caused by jamming or impact, enabling the device to provide stable guidance for the rack body and improving the convenience and efficiency of the transport rack positioning and guiding device during use.

[0019] By incorporating a positioning structure and a return spring design, the positioning plate possesses a certain degree of elasticity. When the rack body impacts the positioning plate, the return spring absorbs the impact energy, achieving flexible contact and preventing damage to the rack body and the positioner from rigid collisions. The positioner can transmit the rack body's position to the back-end terminal in real time, facilitating rack body positioning. After the rack body is removed, the positioning plate automatically swings back to its initial open state under the restoring force of the return spring, preparing for the next rack, thus enabling the device to be used cyclically. This design facilitates rack body positioning and improves the ease of use of the transport rack positioning and guiding device.

[0020] With an adjustable structure, the drive motor can rotate the lead screw, causing the movable block to move inside the adjustment groove. The distance between the two sets of guide frames can be adjusted by the movable block and the support plate. This device is suitable for material rack bodies of different widths, enabling easy adjustment of the distance between the guide frames and improving the applicability of the material rack positioning and guiding device during use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 The present invention provides a positioning and guiding device for a transport rack, comprising a conveyor 1.

[0030] Reference Figures 1-3 , Figure 5 and Figure 6 An adjustment structure 2 is provided on both sides of the top of the conveyor 1. The adjustment structure 2 includes a mounting plate 21, an adjustment groove 22, a lead screw 23, a drive motor 24, a support plate 25, and a movable block 26. The mounting plates 21 are fixed to both sides of the top of the conveyor 1. An adjustment groove 22 is provided in the middle of the interior of the mounting plates 21. A movable block 26 is provided inside the adjustment groove 22. The lead screw 23 is threadedly connected inside the movable block 26. The support plate 25 is fixed to the top of the movable block 26. The drive motor 24 is fixed to the outer wall of one side of the mounting plate 21. One end of the lead screw 23 extends to the outside of the mounting plate 21 and is fixedly connected to the output end of the drive motor 24. The other end of the lead screw 23 extends into the interior of the mounting plate 21 and is rotatably connected to the mounting plate 21. A guide frame 3 is fixed to the top of the adjustment structure 2. The guide frames 3 are symmetrically distributed on both sides of the conveyor 1. The top view of one end of the guide frame 3 is arc-shaped. A material rack body 6 is provided at the top of the conveyor 1.

[0031] When the channel width needs to be adjusted, the drive motor 24 is started by connecting to an external power source. The output shaft of the drive motor 24 drives the lead screw 23, which is fixed to it, to rotate. Since the lead screw 23 is threadedly connected to the movable block 26, and the movable block 26 is restricted to the adjustment groove 22 and cannot rotate, the rotational motion of the lead screw 23 is converted into the linear motion of the movable block 26 along the adjustment groove 22. The movable block 26 is connected to the guide frame 3 through the support plate 25, thereby driving the guide frames 3 on both sides to move closer or further away synchronously, so as to achieve precise adjustment of the channel width.

[0032] Reference Figure 1 , Figure 2 , Figures 4-6 Rolling structures 4 are evenly arranged on the inner side wall of the guide frame 3. The rolling structure 4 includes a round shaft 41, a connecting shaft 42 and a protective strip 43. The round shaft 41 is evenly arranged on the inner side of the guide frame 3. The connecting shaft 42 is fixed at both ends of the round shaft 41. The protective strip 43 is evenly fixed on the outer wall of the round shaft 41. The round shaft 41 is evenly distributed on the inner side of the guide frame 3. The end of the connecting shaft 42 away from the round shaft 41 extends into the interior of the guide frame 3 and is rotatably connected to the guide frame 3.

[0033] When the material rack body 6 is placed at the top of the conveyor 1, the material rack body 6 enters the guide channel in the middle of the guide frame 3 at one end of the guide frame 3 with a certain deviation. At this time, the side of the material rack body 6 will contact the round shaft 41 and the protective strip 43 wrapped around it. The round shaft 41 is rotatably connected to the guide frame 3 through the connecting shafts 42 at both ends. The bottom end of the material rack body 6 is pushed by the conveyor 1, so that the material rack body 6 will drive the round shaft 41 to rotate when it contacts the round shaft 41 and the protective strip 43. During the rolling process, the arc surface of the round shaft 41 will generate a guiding component force on the material rack body 6 pointing to the center of the channel. This force will continue to act until the material rack body 6 is corrected to the center position to achieve precise guidance. At the same time, the rotation of the round shaft 41 can also reduce the friction between the material rack body 6 and the guide frame 3, and prevent the material rack body 6 from getting stuck during the conveying process.

[0034] Reference Figure 1 , Figure 2 , Figures 4-6 Positioning structures 5 are fixed on both sides of the top of the guide frame 3. The positioning structure 5 includes a mounting frame 51, a positioning plate 52, a positioner 53, and a return spring 54. The mounting frame 51 is fixed to one side of the top of the guide frame 3. The positioning plate 52 is hinged to one side of the mounting frame 51. The positioner 53 is fixed to the side of the positioning plate 52 close to the material rack body 6. The return spring 54 is fixed to the side of the positioning plate 52 away from the material rack body 6. The positioning plates 52 are symmetrically distributed on both sides of the conveyor 1. The end of the return spring 54 away from the positioning plate 52 is fixedly connected to one side of the mounting frame 51.

[0035] In its natural state, the positioning plate 52, supported by the return spring 54, faces inward towards the channel and is in a ready state. The material rack body 6 continues to move forward, and its front end will contact the positioner 53 on the positioning plates 52 on both sides. The positioner 53 is equipped with a microcontroller. The positioner 53 will transmit a signal to the back-end terminal through the microcontroller to remind the back-end terminal that the material rack body 6 is about to reach the preset position. The material rack body 6 continues to move. At this time, the pushing force of the material rack body 6 forces the positioning plate 52 to overcome the supporting force of the return spring 54 and begin to compress the return spring 54. At this time, the positioning plate 52 is in an inclined state. The material rack body 6 continues to move forward, and the positioning plate 52 and the positioner 53 will detach from the material rack body 6. At this time, the material rack body 6 reaches the preset position. The positioner 53 will transmit the detachment signal to the back-end terminal through the microcontroller, indicating that the material rack body 6 has been positioned and can be used for subsequent gripping or processing operations. After the task is completed, the material rack body 6 is removed, and the positioning plate 52 can be pushed to reset under the action of the return spring 54.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
