[0002] In modern industrial automation production and logistics warehousing, AGVs (Automated Guided Vehicles) have become indispensable key equipment due to their high efficiency, flexibility, and precision. AGVs can achieve automated material handling and can move shelves. Because of their high versatility, AGVs are suitable for a variety of industries.

[0003] AGVs move shelves, and when goods need to be transferred between two shelves, a pushing mechanism on the shelves is used to move the shelves from one shelf to another. The structure used to control the transfer of goods is relatively complex and difficult to connect, which is not conducive to AGVs controlling the transfer of goods between different shelves.

[0004] For those skilled in the art, how to conveniently achieve docking and transfer of goods is a technical problem that needs to be solved. Utility Model Content

[0005] The core of this utility model is to provide an AGV front docking device. When the AGV trolley drives the material rack to dock with the material cart, the trigger component releases the goods, allowing the goods to be transferred from the material rack to the material cart under the action of gravity, thus conveniently realizing the transfer of goods.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the AGV front docking device of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] This utility model provides an AGV front-end docking device, which is used in the process of goods transfer. It can be driven by an AGV trolley to realize the transfer of goods, and can remove the restriction on the goods through front-end docking. The AGV trolley is not shown in the accompanying drawings of this application.

[0036] The AGV front docking device includes a material rack 10 and a triggering component 20, wherein the triggering component 20 is installed on the material rack 10. The material rack 10 is used to be lifted and moved by the AGV trolley. The bottom of the material rack 10 is provided with a space for the AGV trolley to enter. When the AGV trolley reaches under the material rack 10, the AGV trolley lifts the material rack 10, realizing the synchronous transfer of the material rack 10 and the goods placed on it.

[0037] The rack 10 is used to connect with the cart 30. When the rack 10 and cart 30 are connected, the goods in the rack 10 are transferred to the cart 30. The cart 30 adopts the same structure as the rack 10, but it is not required that the cart 30 and the rack 10 be completely identical. The structure of the cart 30 for receiving goods is similar to a support mechanism, and it is also inclined. Goods on the cart 30 can continue to be transferred in the same way.

[0038] The rack 10 is equipped with a support mechanism 110 for carrying goods. The support mechanism 110 contacts the bottom of the goods, providing support. Figure 3 As shown, the support mechanism 110 is inclined and the two ends of the support mechanism 110 are at different heights, one end is higher and the other end is lower. When the goods are placed on the support mechanism 110, due to the effect of gravity, the goods will move towards the lower end of the support mechanism 110 until they are blocked and limited by the trigger component 20, and cannot be moved off the support mechanism 110.

[0039] The trigger component 20 is installed on the rack 10 and is located at the lower end of the support mechanism 110. The trigger component 20 can block the goods, preventing them from slipping off the support mechanism 110, and can also release the goods when triggered. It should be noted that the trigger component 20 does not need to be directly fixedly connected to the support mechanism 110; the trigger component 20 can simply be positioned on the rack 10.

[0040] The triggering component 20 is provided with a trigger rod 201. The function of the trigger rod 201 is to release the triggering component 20 from obstruction of the goods when it is triggered, so that the goods can slide out from the supporting mechanism 110.

[0041] When the material rack 10 moves directly in front of the material cart 30, the trigger rod 201 can be triggered by the triggering element on the material cart 30, causing the triggering component 20 to release the goods. The goods slide along the supporting mechanism 110 at an angle and are received by the material cart 30.

[0042] The movement of the material rack 10 towards the material cart 30 refers to the process in which the two ends of the material rack 10 and the material cart 30 are aligned and the distance between them is continuously reduced. As the material rack 10 moves closer to the material cart 30, the triggering element on the material cart 30 eventually contacts the triggering rod 201. The triggering rod 201 is subjected to pressure and gives feedback, ultimately releasing the goods.

[0043] It should be noted that the feedback from the trigger lever 201 can be either a physical action or an electronic signal. When the feedback from the trigger lever 201 is a physical action, such as when the trigger lever 201 drives the rotating stop lever 203 to move via the transmission line 204 as described later. When the feedback from the trigger lever 201 is an electronic signal, the trigger lever 201 is set in an electronic switch, and the rotating stop lever 203 is set in a drive motor. When the trigger lever 201 is pressed and triggered, the electronic switch is activated, and the drive motor can drive the rotating stop lever 203 to rotate a certain angle.

[0044] This utility model's AGV front-side docking device triggers the release action through front-side docking. Goods move out of the rack under gravity, and the AGV trolley only needs to continuously move the rack closer to the trolley, requiring only a straight-line translation without turning or changing direction, thus conveniently docking and transferring goods. Since the docking process only requires the AGV trolley to move in a straight line, it reduces the need for grounding weights, eliminates guides, and eliminates multiple grounding weight-guided docking steps, lowering the accuracy requirements for the AGV trolley's movement.

[0045] Based on the above solution, in this utility model, one end of the trigger rod 201 extends beyond the material rack 10. The triggering element on the material cart 30 can be set as a fixed planar structure, with the area of ​​the triggering element on the material cart 30 being larger than the cross-section of the trigger rod 201, allowing for a certain margin of error. When the trigger rod 201 contacts the triggering element, the material rack 10 and the material cart 30 have not yet come into contact; the trigger rod 201 contacts the material cart 30 before the material rack 10, and there is no need for direct collision between the material rack 10 and the material cart 30.

[0046] Combination Figure 1 , Figure 4 As shown, the supporting mechanism 110 of this utility model includes a support rod 111 and rollers 112. The support rod 111 is used to connect with the main structure of the material rack 10, and can be assembled and fixed by bolts or welding. The support rod 111 can be a channel steel structure, or it can be composed of two independent and parallel steel plates.

[0047] Several rollers 112 are rotatably mounted in a row on a support rod 111. The two ends of the rollers 112's axles are rotatably connected to the support rod 111, and the axles of each roller 112 are parallel to each other. The upper surface of each roller 112 should protrude beyond the upper edge of the support rod 111, contacting the bottom surface of the goods. The upper surfaces of all rollers 112 mounted on a support rod 111 remain coplanar, providing uniform support for the goods. When the goods move downwards at an angle along the length of the supporting mechanism 110, the rollers 112 in contact with the goods rotate, allowing the goods to move more smoothly and reducing friction.

[0048] The rack 10 is equipped with two or more support mechanisms 110. Each support mechanism 110 can independently support the goods, and each support mechanism 110 is matched with a trigger component 20.

[0049] Combination Figure 2 , Figure 3 As shown, the supporting mechanisms 110 are distributed at different heights, meaning there are at least two sets of supporting mechanisms 110 at different heights, utilizing vertical space to store goods in layers. Combined with... Figure 2 , Figure 4 As shown, the support mechanisms 110 are arranged at the same height, that is, there are at least two sets of support mechanisms 110 at the same height, which are arranged to store goods using the lateral space.

[0050] The material rack 10 has its lower ends corresponding to the support mechanisms 110 at both ends. Since the support mechanisms 110 are inclined, with one end higher than the other, to allow the material rack 10 to meet more flexible usage requirements, combined with... Figure 3 As shown, the right end of one portion of the support mechanism 110 is lower, and the left end of the other portion of the support mechanism 110 is lower. When goods need to be delivered from the left end, the goods are placed on the support mechanism 110 with the lower left end; when goods need to be delivered from the right end, the goods are placed on the support mechanism 110 with the lower right end. Figure 3 Only the trigger component 20 on the right side is shown; the trigger component 20 on the left side is not shown.

[0051] Based on any of the above technical solutions and their combinations, combined with Figure 5 As shown, the trigger assembly 20 of this utility model includes a mounting base 202, a rotating stop bar 203, and a transmission line 204; the mounting base 202 is a fixed structure and is fixed to the material rack 10. The structure of the mounting base 202 is not limited, and can be combined with... Figure 5 As shown, the middle part of the mounting base 202 is a block 2022, and the other parts are formed by the intersection of horizontal and vertical profile frames 2023. The profile frames 2023 can be made of D30 profile splicing.

[0052] The mounting base 202 is provided with a sliding groove for accommodating the trigger rod 201, that is, a sliding groove is provided on the block body 2022. The trigger rod 201 is slidably inserted into the mounting base 202. A sliding bearing is provided between the mounting base 202 and the trigger rod 201, and the trigger rod 201 can slide along... Figure 5 The bidirectional arrow in the middle is shifted in direction.

[0053] Combination Figure 3 As shown, the trigger rod 201 extends horizontally along its length, and its extended end can move horizontally relative to the mounting base 202. The direction of movement of the trigger rod 201 is consistent with the direction of movement of the AGV trolley's front end during docking.

[0054] A sliding bearing is located at the bottom of the trigger rod 201, and a slide rail for accommodating the sliding bearing is provided at the bottom of the sliding groove. When the trigger rod 201 slides, the sliding bearing moves within the slide rail.

[0055] In this embodiment, combined with Figure 5 As shown, the trigger rod 201 has limiting members 2011 at both ends. The limiting members 2011 are located outside the sliding groove, and the radial dimension (perpendicular to the axis of the trigger rod 201) of the limiting members 2011 is larger than the radial dimension of the trigger rod 201. The two limiting members 2011 limit the trigger rod 201. A buffer member, which can be a silicone pad, is provided at the end of the two limiting members 2011 near the sliding groove. The buffer member acts as a buffer when the limiting members 2011 are close to the mounting base 202.

[0056] The rotating stop lever 203 is rotatably mounted on the mounting base 202, and the axis of rotation of the rotating stop lever 203 is parallel to the translational direction of the trigger lever 201. The rotating stop lever 203 includes a rotating shaft 2031 and a stop block 2032. The rotating shaft 2031 is cylindrical, and the mounting base 202 is provided with a hinge groove, such as... Figure 5 As shown, the upper surface of the mounting base 202 has two protruding hinge protrusions 2021, each with a hinge groove. The hinge grooves on the two hinge protrusions 2021 are coaxially connected. The rotating shaft 2031 is hinged to the hinge groove on the mounting base 202, allowing the rotating shaft 2031 to rotate relative to it. A stop block 2032 is fixed to one end of the rotating shaft 2031. The stop block 2032 is perpendicular to the length direction of the rotating shaft 2031, or forms an acute angle with the length direction of the rotating shaft 2031, and can block goods.

[0057] When the trigger lever 201 moves horizontally, it is driven by the transmission line 204, which in turn drives the rotating stop lever 203 to rotate, thereby releasing the block 2032 from obstructing the goods. The transmission line 204 can be made of steel cable or similar materials, and it does not deform elastically when stretched. Figure 5 As shown, a protruding fixed rod 2033 is provided on the side wall of the rotating shaft 2031. The transmission line 204 is fixed to this fixed rod 2033. When the transmission line 204 applies a lateral pulling force to the fixed rod 2033, it applies a rotational torque to the rotating shaft 2031, pulling the rotating shaft 2031 to rotate. When the stop block 2032 faces upward, it can block the goods. When the stop block 2032 rotates to the horizontal position, it releases the obstruction of the goods.

[0058] Combination Figure 5As shown, the mounting base 202 is equipped with a reversing block 206 for changing the direction of the tension in the transmission line 204. The reversing block 206 causes the transmission line 204 to change direction, thereby converting the linear motion of the trigger rod 201 into a tension perpendicular to the direction of the trigger rod 201's motion. This tension, in turn, causes the transmission line 204 to pull the rotating shaft 2031 to rotate. The reversing block 206 can be a cylindrical rod or a roller structure.

[0059] Combination Figure 5 As shown, an elastic reset member 205 is provided between the rotating stop lever 203 and the mounting base 202. The elastic reset member 205 provides a reset force to the rotating stop lever 203, causing the stop block 2032 to return to the material blocking state. The elastic reset member 205 gives the rotating stop lever 203 a tendency to rotate. The rotation direction applied by the elastic reset member 205 to the rotating stop lever 203 is opposite to the rotation direction applied by the transmission line 204 to the rotating stop lever 203. When the trigger lever 201 stops triggering, the elastic reset member 205 causes the rotating stop lever 203 to return to the state of blocking the goods.

[0060] The elastic reset element 205 can be in the form of a torsion spring, a tension spring, or an elastic band.

[0061] Furthermore, in combination Figure 6 As shown, the rotating shaft 2031 of the rotating stop 203 is provided with at least two grooves 2034 arranged along the length of the rotating shaft 2031. The elastic reset member 205 is detachably fixed to the rotating stop 203 by the fixing assembly 207. The fixing assembly 207 includes a first wedge 2071 and a second wedge 2072. One end of the first wedge 2071 is provided with a first step 20711, and one end of the second wedge 2072 is provided with a second step 20721. The first step 20711 and the second step 20721 are symmetrically arranged. The protruding part of the first step 20711 of the first wedge 2071 is disposed in one groove 2034, and the protruding part of the second step 20721 of the second wedge 2072 is disposed in the other adjacent groove 2034. The first wedge 2071 and the second wedge 2072 are fixed by screws 2073, and thus fixed to the surface of the rotating stop 203.

[0062] The transmission line 204 is also fixed to the rotating stop 203 and the trigger rod 201 in this manner. The reversing stop 206 is fixed to the profile frame 2023 of the mounting base 202 in this manner.

[0063] Combination Figure 5 As shown, a rotating stop bar 203, a transmission line 204, and an elastic reset member 205 are respectively installed on both sides of the trigger rod 201. One trigger rod 201 can control the action of two rotating stop bars 203 at the same time, so that the two rotating stop bars 203 can block a cargo, ensuring a more stable blocking effect on the cargo.

[0064] Combination Figure 5 As shown, when the stop block 2032 blocks the goods, it faces upward. If necessary, the installation direction of the entire trigger component 20 can also be reversed, at which time the stop block 2032 protrudes downward to block the goods. These specific configurations should all be included within the protection scope of this utility model.

[0065] A QR code is provided at the bottom of the material rack. The AGV trolley recognizes the QR code at the bottom of the material rack and transports the material to the designated unit station to dock with the material car. The trigger rod 201 drives the transmission line 204 to rotate towards the rotating stop rod 203 and is reset by the elastic reset member 205. After the rotating stop rod 203 releases the obstruction of the goods, the goods move along the supporting mechanism 110 and the material is transferred by utilizing the height difference.

[0066] This device boasts a high degree of automation and utilizes AGVs for cargo transfer. It employs a front-facing docking trigger, eliminating the need for repeated docking and positioning, saving 30 seconds per docking attempt and resulting in a minimum annual saving of 63,000 RMB. The docking accuracy requirements are reduced (due to fewer ground codes, elimination of guidance, and elimination of multiple ground code-guided docking attempts), leading to greater fault tolerance.

[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
