DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example:

[0038] AGV forklift is widely used in industries such as industry and manufacturing, especially in the logistics field where goods need to be transported and packaged. Usually, electromagnetic tracks are laid on the workshop floor in advance, and the forklift will rely on its own guidance system to move and act according to the information brought by the electromagnetic track without the need for manual piloting. In addition, it has the characteristics of clean production and relies on batteries to provide power, so there is no noise or pollution during operation.

[0039] In the process of transporting goods, many kinds of goods are usually encountered. Since the goods are of different sizes, their center of gravity will also be different. Therefore, during the placement process, even if they are placed flat, the inertia generated when the forklift moves and the centrifugal force when turning will cause the goods to shift or even be thrown out of the forklift, causing inconvenience to the transportation of the goods.

[0040] For this purpose, refer to the attached Figures 1-11, this solution proposes an AGV forklift for logistics. When the goods move onto the forklift arm, through the cooperation between the first-level lifting mechanism 21 and the second-level lifting mechanism 22, the goods can be tilted and stacked on the inclined storage plate 111 in the same way, enabling the goods to be placed obliquely on the vehicle body 1 to ensure the stability of the goods during handling (increasing the friction on the end face of the goods).

[0041] Specifically, the guiding, navigation, and driving structures provided inside the vehicle body 1 in this solution are all well-known technologies, and there is no need to elaborate too much in this solution. When working in the workshop, first, the robotic arm used to grab the goods (which can be manual or other equivalent structures for grabbing the goods to the designated location) places the goods on the lifting member 2. The lifting member 2 is composed of the first-level lifting mechanism 21 and the second-level lifting mechanism 22 that can move up and down in the same direction. Among them, the first-level lifting mechanism 21 includes a housing that can be guided and move along one side direction of the vehicle body 1. The driving and traction structure of the housing is a well-known technology. In this solution, a push rod is used as the driving element, and no specific limitation is made. The second-level lifting mechanism 22 can move in the same direction as the first-level lifting mechanism 21.

[0042] The vehicle body 1 is provided with a storage rack 11 for carrying goods. The lifting member 2 is movably installed on one side of the vehicle body 1. The bottom of the second-level lifting mechanism 22 is provided with a lifting plate 221 parallel to the ground, which plays a major load-bearing role. Its upper end is also driven and traction-stretched by a push rod in the same way as the first-level lifting mechanism 21. A rotating plate 223 that can rotate towards the vehicle body 1 direction is hinged at the upper end of the lifting plate 221. A guiding groove 12 is respectively opened along the length direction on both sides of the rotating plate 223. And a connecting arm 212 is respectively hinged on both sides of the first-level lifting mechanism 21. One end of each connecting arm 212 is inserted into the adjacent guiding groove 12. Thus, when the first-level lifting mechanism 21 starts to rise, the part of the connecting arm 212 inserted into the guiding groove 12 will gradually slide in the guiding groove 12 until it moves to the end of the guiding groove 12. During this process, as the first-level lifting mechanism 21 continues to rise, it will drag the rotating plate 223 to start rotating towards the vehicle body 1 side, and the goods placed on the rotating plate 223 will gradually tilt and slide as the rotating plate 223 rotates until they fall onto the storage plate 111.

[0043] During the rising process of the goods, in addition to the rotating plate 223 undergoing a certain angle of flipping, and as the first-level lifting mechanism 21 continues to rise, it will gradually drive the second-level lifting mechanism 22 to move upward continuously (at this time, the driving structure connected to the second-level lifting mechanism 22 is in the closed state) until it reaches the storage plate 111 or the flat plate 112 where the goods are to be placed. At the same time, on one side of the second-level lifting mechanism 22 (attached Figures 1-2On the left side (in the figure) of it, a connecting block 224 is also provided. The connecting block 224 has a concave structure with the concave surface facing the first-level lifting mechanism 21, and is located on the moving path of the first-level lifting mechanism 21. During the movement of the first-level lifting mechanism 21, when the rotating plate 223 has completed rotation, the connecting block 224 will sleeve on the upper end of the first-level lifting mechanism 21 and move synchronously with the movement of the first-level lifting mechanism 21. An opening 225 for the passage of goods is provided on the left end face of the second-level lifting mechanism 22. When the bottom side of the opening 225 is on the same plane as the storage plate 111, it will slide onto the storage plate 111 along the trend.

[0044] And a rotatable acceleration roller 222 is also provided on the lifting plate 221 and on one side of the opening 225. When the goods are about to move onto the storage plate 111, the friction between the lifting plate 221 (rotating plate 223) and the goods is reduced. In the actual use process, a certain pusher claw structure can be used as the structure for driving the goods to leave the lifting plate 221, without specific limitation.

[0045] When dealing with the placement of some heavy objects that do not need to be placed obliquely or some ordinary goods, the second-level lifting mechanism 22 is directly lifted, so that the second-level lifting mechanism 22 moves upward until it reaches above the vehicle body 1 and above the storage plate 111. At this time, the first-level lifting mechanism 21 can be rotated manually or driven, and the goods will slide onto the flat plate 112 to achieve the purpose of flat placement.

[0046] And during the process of the goods sliding from the rotating plate 223 to the storage plate 111, a certain resistance needs to be provided to avoid excessive impact force. Therefore, a tape roll 113 is provided above the inclined surface of the storage plate 111. The adhesive surface of the tape roll 113 faces the side of the rotating plate 223. When the rotating plate 223 and the upper plane of the storage plate 111 are on the same plane, the goods slide from the rotating plate 223 onto the storage plate 111, and the adhesive surface of the tape roll 113 intersects with the moving path of one side of the goods. A elastically rotatable V-shaped roller 114 is provided on the side of the tape roll 113 away from the goods. One side of the V-shaped roller 114 intersects with the moving path of the goods, and the other side can abut against the upper end of the goods when the V-shaped roller 114 rotates. The rotating plate 223 is movably connected to the first-level lifting mechanism 21 and can be arranged at an oblique angle with the lifting plate 221 along with the movement of the first-level lifting mechanism 21.

[0047] When the goods slide down from the turning plate 223, one end facing the adhesive tape roll 113 will stick to the side end face of the goods. Immediately afterwards, one side end face of the adhesive tape roll 113 in contact with the goods will abut against the V-shaped roller 114 located on one side of the adhesive tape roll 113. And during the sliding process of the goods, one end of the V-shaped roller 114 will be gradually abutted, causing the entire V-shaped roller 114 to start rotating at a certain angle until the other side abuts against the upper end of the goods. The V-shaped roller 114 will abut against the goods in a state with the concave surface facing downwards, and the just-covered adhesive tape will be abutted and compacted.

[0048] An inductive hot cutter is also provided between the adhesive tape roll 113 and the V-shaped roller 114, which can trigger the cutting of the dragged adhesive tape roll 113 when the goods are separated. Specific sensing elements can apply various sensors such as gravity, tension, and distance, which are well-known technologies and are not specifically limited here.

[0049] Through the above settings, not only is a certain resistance provided by the adhesive tape, but also the package is sealed, reducing subsequent additional manual packaging processes and improving the processing efficiency of the enterprise. The same packaging structure is provided above the flat plate 112.

[0050] At the same time, in order to ensure that the upper box lids of the goods entering the storage plate 111 will not flip to both sides of the goods, a connecting plate 2231 is vertically provided at one side of the upper end of the turning plate 223. And one end of the connecting plate 2231 facing the vehicle body 1 is provided with a chute 2232 along the width direction of the vehicle body 1. Two sliding shafts 2233 are distributed up and down in the chute 2232. In this example, two folding frames 2235 are symmetrically distributed and are both sleeved on the two sliding shafts 2233 for guiding and sliding. A return spring 2234 is sleeved on both sides of each sliding shaft 2233 and abuts against one end of the folding frame 2235 away from the middle of the folding frame 2235. When the manipulator (or other components) holds the goods and places them on the turning plate 223, they will be placed in the middle of the two folding frames 2235, which not only plays a role in correcting and fine-tuning (preventing the placement orientation from tilting and causing the goods to deviate from the expected route during sliding), but also can flip the box lid through the two folding frames 2235.

[0051] Specifically, each folding frame 2235 is arranged parallel to the turning plate 223, and the corresponding end faces of the two folding frames 2235 are both inclined planes. When the goods are inserted into the middle of the two folding frames 2235, they will abut against the inclined planes, and the distance between the two folding frames 2235 will be gradually increased. During sliding, the friction between the side end of the folding frame 2235 and the goods is small, and the friction provided by the return spring 2234 to the goods is limited and is not sufficient to block the normal sliding of the goods.

[0052] The storage board 111 in this solution includes an inclined board 1111 and a receiving board 1112. The inclined board 1111 is installed obliquely on the vehicle body 1, and the receiving board 1112 is hinged (rotating upward) at one end of the inclined board 1111 facing the lifting member 2. When the height of the goods is not particularly high, that is, when the storage board 111 and the end face of the rotated rotating board 223 are flush, and the height of the goods is not enough to stick to one end of the tape roll 113, at this time, a lifting board 211 is hinged at one end of the secondary lifting mechanism 22 facing the vehicle body 1. The lifting board 211 is arranged below the receiving board 1112 and is staggered. The lifting board 211 in this example can only rotate unidirectionally, upward. When the lifting board 211 abuts against the lower end of the storage board 111, it will drive the storage board 111 to rotate at a certain angle as the secondary lifting mechanism 22 rises. At this time, the lifting board 211 will not rotate until the lifting board 211 and the storage board 111 are misaligned. When the lifting board 211 returns with the secondary lifting mechanism 22, it will abut against the upper end of the storage board 111. At this time, the lifting board 211 will start to rotate at a certain angle until it slides to the lower end of the storage board 111.

[0053] During the movement of the secondary lifting mechanism 22, the height of the goods rises accordingly until its subsequent movement path can be adhered to the tape (the component used to judge whether the goods reach the predetermined location is a well-known technology, which is not limited in this solution. A millimeter-wave radar with a relatively small overall size and various induction sensors can be used). When it reaches the position where it can be adhered, the above-mentioned tape sticking process is repeated. Similarly, it will not be elaborated here.

[0054] In this solution, in addition to the inclined storage board 111, a flat board 112 parallel to the ground is also provided. The two boards are distributed up and down on the vehicle body 1. The storage rack 11 is overall rectangular. An inlet is provided at one end facing the lifting member 2, and an outlet 115 is provided on its outer side for the unloading passage. The skeleton structure on the storage rack 11 and the storage board 111 and the flat board 112 form a space for storing different goods (a box-shaped space facing the lifting member 2 and having an outlet 115 on one side).

[0055] To ensure the smooth rolling of the goods, two parallel grooves 1122 are opened on the upper end surface of the flat board 112. A rotatable turntable 116 is provided in each groove 1122. At the same time, a rotatable roller 1121 is provided at the upper end of the turntable 116. The roller 1121 is parallel to one side of the flat board 112 (it can face the inlet or the outlet 115).

[0056] When the goods move on the flat board 112, at this time, the roller 1121 is rotated to the direction that can rotate towards the goods side. When the goods roll onto the roller 1121, the friction between the goods and the flat board 112 will be reduced, ensuring the smooth placement of the goods.

[0057] When the goods need to be unloaded, the roller 1121 is rotated to a direction facing one end of the discharge port 115. At this time, an unloading track is set at the discharge port 115 (mounted on one side of the discharge port 115, and the goods slide out from the track) or the goods are moved manually. In this solution, only two layers are set. In practice, multiple layers of similar storage space can be added. The greater the height, the more inconvenient it is to unload the goods. The steerable roller 1121 in this solution can effectively solve the problems of insufficient impact force of the goods and inconvenience in unloading. There is no need for additional operation to push the goods out of the vehicle body 1, which truly achieves energy-saving and noise-free processing.

[0058] Specifically, a gear 1161 is connected to the bottom of each turntable 116 , and a sliding door 13 that can block the discharge port 115 is provided on one side of the discharge port 115 , a friction strip 131 is provided on the sliding door 13 , and a helical tooth groove that meshes with the gear 1161 is opened on one side of the friction strip 131 .

[0059] When the sliding door 13 is closed, even if the cargo is subjected to a force sufficient to shift the cargo, the cargo cannot pass through the discharge port 115 due to the limit of the discharge port 115 ;

[0060] When the sliding door 13 is opened, the beveled teeth on the friction strip 131 will cooperate with the gear 1161, allowing the gear 1161 to start rotating and change the direction of the roller 1121. When it is fully opened, the roller 1121 is parallel to the plane of the discharge port 115 and can start rotating toward one end of the discharge port 115. At this time, you only need to simply push the goods onto the roller 1121 to easily complete the unloading process.

[0061] In order to further improve the unloading speed, the flat plate 112 in the present scheme is elastically hinged on the vehicle body 1, and an arc-shaped protrusion 1123 is provided at the lower end of the flat plate 112 (in the present scheme, it is arranged in the middle of one side of the discharge port 115), and a resistance bar 132 is provided on the sliding door 13, one end of the resistance bar 132 is inclined (inclined upward) and is in contact with the position of the protrusion 1123 near the left side. When the sliding door 13 starts to move, the protrusion 1123 will gradually contact the right side of the inclined surface of the resistance bar 132, and the flat plate 112 will be pressed downward, so that the flat plate 112 will rotate slightly downward to increase the unloading efficiency.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
