Technical Field
[0001] This utility model relates to the field of loading and unloading conveyors, and in particular to a multi-functional loading and unloading conveyor. Background Technology
[0002] A loading / unloading conveyor is a conveying device used in automated production lines to automatically load and unload materials. It transports materials from one location to another, thereby automating material handling, improving production efficiency, and reducing manual labor intensity. The loading / unloading conveyor is equipped with a conveyor chain to transport heavy products, and clamping blocks on the conveyor chain are used to position and transport the products.
[0003] Patent CN211711828U, published on the China Patent Website, discloses a plastic pipe loading and unloading conveying device. This device includes a conveying mechanism, a loading box mechanism, and a unloading box mechanism. The conveying mechanism has a conveying chain that wraps around a left and right conveying sprocket. Conveying support seats are evenly distributed along the conveying chain. Each support seat includes a bottom support plate and side support plates. The bottom support plate has a V-shaped support groove, and the side support plates have arc-shaped support grooves. The loading box mechanism has a hollowed-out left side center of the loading box bottom plate and a hollowed-out right side center of the loading box edge, forming a loading slot. The unloading box mechanism has a hollowed-out upper sealing plate and a hollowed-out right side center of the unloading box bottom plate, forming a unloading slot. This plastic pipe loading and unloading conveying device not only enables rapid conveying and loading / unloading of plastic pipes, but also provides very stable conveying and loading / unloading. Furthermore, its reasonable structure replaces manual loading and unloading, resulting in a high degree of automation.
[0004] The loading and unloading conveyor of the plastic pipes cannot achieve high-precision transportation during transport, and there are no error-proofing measures for the transported products. Utility Model Content
[0005] In view of this, the present invention provides a multifunctional loading and unloading conveyor to prevent products from being installed upside down, and to correct the position of the products to achieve precise transportation, so as to meet the needs of product loading and unloading, and to assist in product coding during product loading and unloading.
[0006] A multifunctional loading and unloading conveyor includes a machine tool body, two conveyor chains arranged parallel to each other on the machine tool body, and multiple spaced-apart clamping blocks on the conveyor chains, with the clamping blocks on the two conveyor chains arranged opposite each other. It includes a loading and unloading mechanism disposed above the conveyor chains, a positioning mechanism disposed on the loading and unloading mechanism, and a foolproof mechanism disposed on the machine tool body. The loading and unloading mechanism includes a lifting assembly, a loading plate disposed on one side of the conveyor chain's extension direction, and a unloading plate disposed on the other side of the conveyor chain's extension direction. The lifting assembly is disposed below the loading plate or the unloading plate. Each loading and unloading plate is lifted by one of the lifting assemblies, and each loading and unloading plate supports one material. The unloading plate is provided with multiple clamping frames. The positioning mechanism includes multiple side-push cylinders corresponding to the loading plate or the unloading plate, multiple positioning cylinders corresponding to the loading plate or the unloading plate, multiple horizontal push cylinders arranged in pairs on one loading plate, multiple clamping plates corresponding to the horizontal push cylinders, and multiple position detectors corresponding to both ends of the product. One side-push cylinder corresponds to one positioning cylinder, meaning the side-push cylinder and the positioning cylinder are located on opposite sides of the conveyor chain and correspond to one loading plate or unloading plate. The side-push cylinder pushes one end of the product, causing the other end to abut against the positioning cylinder. A horizontal push block is fixedly installed at the output end of the horizontal push cylinder, pushing one side of the product so that the other side abuts against the clamping plate. The position detectors are respectively positioned corresponding to the clamping frame, the clamping block of the stationary conveyor chain, and the laser marking device.
[0007] Furthermore, the lifting assembly is disposed below the upper or lower plate. The lifting assembly includes a base plate, two slide rail assemblies extending on the base plate, and a lifting cylinder disposed in the middle of the slide rail assemblies. The slide rail mechanism is provided with sliders, and different sliders are fixedly connected to the same mounting plate. The mounting plate abuts against the upper plate. The output end of the lifting cylinder is fixedly connected to the upper plate or the lower plate.
[0008] Furthermore, the error prevention mechanism includes multiple inclined error prevention blocks disposed near the output end of the side push cylinder close to the feeding plate, and multiple flat error prevention blocks disposed near the output end of the positioning cylinder close to the feeding plate. The inclined error prevention blocks are used to place the inclined side of the product, and the flat error prevention blocks are used to place the straight side of the product.
[0009] Furthermore, the side-push cylinder and the positioning cylinder are equipped with lifting components, which move to below the conveyor chain when the product finishes lateral calibration.
[0010] Furthermore, the clamping frames are arranged in pairs to clamp the two sides of a product.
[0011] Furthermore, the error prevention mechanism also includes a vision detector disposed on the outside of the machine tool body. The vision detector is close to the loading plate and disposed on the outside of the machine tool body, corresponding to the product side. The vision detector is disposed at the output end of the cylinder through a connecting plate. The output direction of the cylinder is the same as the extension direction of the conveyor chain.
[0012] Furthermore, the error prevention mechanism also includes two product detectors respectively set on different unloading plates, which are used to perform error prevention detection before the robotic arm picks up the product.
[0013] Compared with existing technologies, this utility model provides a multi-functional loading and unloading conveyor equipped with the positioning mechanism and the error-proofing mechanism, achieving precise transportation and error-proofing detection of products during loading and unloading transportation and auxiliary product laser marking. The side-push cylinder of the positioning mechanism pushes the product to abut against the positioning cylinder for longitudinal calibration. The lateral push cylinder pushes the product to abut against the clamping plate for lateral calibration. The positioning detector assists in the precise transfer of the product from the loading plate to the conveyor chain and from the conveyor chain to the unloading plate. The inclined and flat error-proofing blocks of the error-proofing mechanism ensure that the product can only be placed on the loading and unloading plates from a single direction, preventing incorrect placement in the opposite direction. The vision detector detects the product's color, structure, and reinforcing ribs to achieve error-proofing detection. The product detector checks whether the product is the correct model to be grasped, in order to cooperate with the robotic arm for grasping. Attached Figure Description

[0019] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0020] Please see Figures 1 to 5 This is a structural schematic diagram of a multifunctional loading and unloading conveyor provided by this utility model. The multifunctional loading and unloading conveyor includes a machine tool body 800, two conveyor chains 900 arranged in parallel on the machine tool body 800, a loading and unloading mechanism 10 arranged above the conveyor chains 900, a positioning mechanism 20 arranged on the loading and unloading mechanism 10, and a foolproof mechanism 30 arranged on the machine tool body 800.
[0021] First of all, it should be noted that the multi-functional loading and unloading conveyor is used to transport products and to perform laser marking (not shown in the figure) during the transport process. The products are long and narrow with one end being flat and the other end being inclined.
[0022] The machine tool body 800 is used to support the above-mentioned functional modules. Therefore, the bed is equipped with a variety of functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. These can be set according to actual needs, and will not be described in detail here.
[0023] The conveyor chain 900 consists of a frame, a rotary motor, a drive wheel, a driven wheel, and a conveyor belt. The conveyor chain 900 is existing technology, and its specific structure will not be described in detail here. The conveyor chain 900 is equipped with multiple spaced-apart clamping blocks 901, with the clamping blocks 901 on two conveyor chains 900 arranged opposite each other, for clamping the product. The clamping blocks 901 on different conveyor chains 900 respectively support both ends of the product, preventing the product from tilting during transportation.
[0024] The loading and unloading mechanism 10 includes two lifting components 11, an loading plate 12 disposed on one side of the conveyor chain 900 extension direction, and a unloading plate 13 disposed on the other side of the conveyor chain 900 extension direction.
[0025] Two lifting assemblies 11 are respectively disposed below the upper plate 12 or the lower plate 13. Each lifting assembly 11 includes a base plate 111, two slide rail assemblies 112 extending from the base plate 111, and a lifting cylinder 113 disposed between the slide rail assemblies 112. Each slide rail assembly 112 has a slider 1121, with different sliders 1121 fixedly connected to the same mounting plate 1122, which abuts against the upper plate 12. The slide rail assembly 112 assists the lifting cylinder 113 in guiding the upper plate 12, preventing the upper plate 12 or the lower plate 13 from becoming unbalanced and falling. The output end of the lifting cylinder 113 is fixedly connected to the upper plate 12 or the lower plate 13, adjusting the height of the upper plate 12 or the lower plate 13 to facilitate manual installation or robotic arm handling.
[0026] Each of the upper and lower feeding plates 12 and 13 is lifted by a lifting assembly 11, and each of the upper and lower feeding plates 12 and 13 supports a material and assists in the detection and calibration of the material's position. The lower feeding plate 13 is provided with multiple clamping frames 131, which are arranged in pairs to clamp the two sides of a product, for precise positioning of the product from the conveyor chain 900 to the lower feeding plate 13 during unloading.
[0027] The positioning mechanism 20 includes multiple side-push cylinders 21 corresponding to the loading plate 12 or the unloading plate 13, multiple positioning cylinders 22 corresponding to the loading plate 12 or the unloading plate 13, multiple horizontal push cylinders 23 arranged in pairs on one loading plate 12, multiple clamping plates 24 corresponding to the horizontal push cylinders 23, and multiple position detectors 25 corresponding to both ends of the product.
[0028] One side-push cylinder 21 is provided for each positioning cylinder 22, that is, the side-push cylinder 21 and the positioning cylinder 22 are respectively located on both sides of the conveyor chain 900, and are provided for one loading plate 12, unloading plate 13, or laser marking device. The side-push cylinder 21 and the positioning cylinder 22 are used to adjust the longitudinal position of the product conveyed to the interval between them. The side-push cylinder 21 pushes one end of the product to the side, so that the other end abuts against the positioning cylinder 22. The positioning cylinder 22 consists of two cylinders to facilitate precise positioning.
[0029] The feeding plate 12 has a horizontal push cylinder 23 and a matching clamping plate 24 on each side to calibrate the lateral position of the product. A horizontal push block 231 is fixedly installed at the output end of the horizontal push cylinder 23. The horizontal push block 231 pushes one side of the product so that it abuts against the clamping plate 24 on the other side, calibrating the lateral position of the product. After being positioned by the horizontal push cylinder 23 and the clamping plate 24, the product's position corresponds to the clamping block 901 on the stationary conveyor chain 900. The horizontal push cylinder 23 and the clamping plate 24 ensure that when transferring products from the feeding plate 12 to the conveyor chain 900, the products can be accurately moved into the clamping block 901 without manual readjustment, increasing production efficiency. During unloading, the clamping blocks 901 on the conveyor chain 900 are activated by the positioning detector 25, ensuring that products between two adjacent clamping blocks 901 correspond to the clamping frame 131 on the unloading plate 13.
[0030] The positioning detectors 25 are respectively positioned corresponding to the clamping frame 131, the clamping block 901 of the stationary conveyor chain 900, and the laser marking device. During loading, as the product is transported from the loading plate 12 to the conveyor chain 900, the positioning detectors 25 are positioned corresponding to the clamping blocks 901 on the conveyor chain 900 to ensure accurate product installation. During unloading, as the product is transported from the conveyor chain 900 to the unloading plate 13, the positioning detectors 25 are positioned on the unloading plate 13 and respectively corresponding to the clamping frame 131. During laser marking, the positioning detectors 25 are positioned between the conveyor chain 900 and the side-push cylinder 21 to detect the product.
[0031] The error prevention mechanism 30 includes multiple inclined error prevention blocks 31 disposed near the output end of the side push cylinder 21 close to the loading plate 12, multiple flat error prevention blocks 32 disposed near the output end of the positioning cylinder 22 close to the loading plate 12, a vision detector 33 disposed on the outside of the machine tool body 800, and two product detectors 34 disposed on different unloading plates 13.
[0032] One end of the product is flat, and the other end is sloped. Therefore, to prevent the product from being placed upside down, the sloped anti-misalignment block 31 is used to place the product on the sloped side, and the flat anti-misalignment block 32 is used to place the product on the flat side, preventing the product from being grasped by the robotic arm when both ends are upside down. Because one side of the product is sloped, when the side-push cylinder 21 comes into contact with the product, the product is blocked by the side-push cylinder 21 and cannot move to the conveyor chain 900. Therefore, the side-push cylinder 21 and the positioning cylinder 22 are equipped with a lifting assembly, which moves the product below the conveyor chain 900 when the lateral calibration is completed.
[0033] The vision detector 33 is located near the loading plate 12 and is positioned on the outer side of the machine tool body 800, corresponding to the product side. The vision detector 33 is connected to the output end of the cylinder via a connecting plate, and the output direction of the cylinder is the same as the extension direction of the conveyor chain 900. The vision detector 33 is used to detect the color and outline of the product. After the flat anti-foolproof block 32 and the inclined anti-foolproof block 31 pass the error-proof detection, further error-proof detection is performed by detecting the reinforcing ribs on the product. After the vision detector 33 passes, the lifting assembly 11 controls the loading plate 12 to descend, transporting the product onto the conveyor chain 900.
[0034] Multiple product detectors 34 are respectively disposed on different feed plates 13 to correspond to different products. The vision detector 33 detects whether the product is the correct model to be grasped. The product detectors 34 are used to perform foolproof detection before the robotic arm grasps the product. After the product passes the detection, the robotic arm grasps the product. The structures of the vision detectors 33 and the product detectors 34 are prior art and will not be described in detail here.
[0035] The specific steps are as follows: 1. The product is manually placed on the loading plate 10. The side-push cylinder 21 pushes the product to abut against the positioning cylinder 22, and the horizontal push cylinder 23 drives the product to abut against the clamping plate 24. After achieving lateral and transverse positioning of the product, the side-push cylinder 21 retracts and the positioning cylinder 22 moves to below the conveyor chain 900. 2. After the vision detector 33 performs visual inspection on the product and passes inspection, the lifting assembly 11 lowers to move the product from the loading plate 12 to the conveyor chain 900. 3. After the positioning detector 25 near the loading plate 12 performs positioning inspection on the product and passes inspection, the conveyor chain 900 begins to move. 4. When the positioning detector 25 near the laser marking equipment detects and passes inspection on the product, the conveyor chain 900 stops moving. After the side-push cylinder 21 pushes the product to abut against the positioning cylinder 22, laser marking is performed. After laser marking is completed, the side-push cylinder 21 retracts, the positioning cylinder 22 extends, and the conveyor chain 900 continues to move. 5. When the positioning detector 25 near the unloading plate 13 detects and passes the product, the conveyor chain 900 stops moving. The lifting assembly 11 lifts the unloading plate 20 to a specific height and stops, and the side-push cylinder 21 pushes the product to abut against the positioning cylinder 22. 6. The product detector 34 detects the product, and the robotic arm picks up the product. 7. All cylinders reset, and the above steps are repeated.
[0036] Compared with existing technologies, this utility model provides a multi-functional loading and unloading conveyor equipped with a positioning mechanism 20 and a mistake-proofing mechanism 30, achieving precise transportation and mistake-proofing detection of products during loading and unloading transportation and assisting in laser marking of products. The side-push cylinder 21 of the positioning mechanism 20 pushes the product to abut against the positioning cylinder 22 for longitudinal calibration. The lateral push cylinder 23 pushes the product to abut against the clamping plate 24 for lateral calibration. The positioning detector 25 assists in the precise transfer of the product from the loading plate 12 to the conveyor chain 900 and from the conveyor chain 900 to the unloading plate 13. The inclined and flat mistake-proofing blocks 31 and 32 of the mistake-proofing mechanism 30 ensure that the product can only be placed on the loading and unloading plates 12 and 13 from a single direction, preventing incorrect placement in the opposite direction. The vision detector 33 performs mistake-proofing detection by detecting the product's color, structure, and reinforcing ribs. The product detector 34 detects whether the product is the correct model to be grasped, in order to cooperate with the robotic arm's grasping.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
