Description

Technical Field

[0001] The present invention relates to the technical field of intelligent conveying, and more particularly to a construction material conveying device. Background Art

[0002] In the actual construction process, different types of building materials will be used. These building materials are all loaded in cargo containers. When the cargo containers arrive at the site, intelligent hanging equipment is generally used to classify and stack the cargo containers containing different types of building materials for subsequent vehicle transportation.

[0003] Cargo boxes are generally equipped with nameplates that indicate the type of building materials inside. Existing intelligent hanging equipment generally relies on a visual system to identify the nameplates to determine the type of building materials inside the boxes. Cargo boxes containing the same type of building materials are then stacked together. Sometimes, there are cases where the boxes are missing or loaded incorrectly. At this time, the weight of the boxes will vary from the standard range. These boxes are called defective products. The visual system can only determine the type of building materials inside the boxes with the help of the nameplates and cannot detect defective products. These defective products will normally flow into the subsequent classification and stacking areas, affecting the accuracy of packing. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-Figure 7The present invention provides a construction material conveying equipment, including a Y-axis linear motion module 1, a gantry 2 and a cargo box 3. The gantry 2 is provided with an X-axis linear motion module 21 and a crane 22. The crane 22 is provided with a hook 221. The hook 221 is provided with a vision module 4. Through the three-axis coordinated motion combined with machine vision recognition, the automatic classification and processing capabilities of construction materials can be significantly improved, and the intensity and error rate of manual operation can be effectively reduced.

[0034] A pushing mechanism 5 is provided at the bottom of the hook 221, and the pushing mechanism 5 is used to push the defective cargo box 3 to the defective conveyor belt. The defective cargo box 3 is a cargo box 3 in which the loading amount of building materials deviates from the actual required amount. A lifting lug 31 and a nameplate 32 are provided on the top of the cargo box 3. The same type of building materials are loaded in a single cargo box 3, and each type of building material corresponds to a nameplate 32. The design of the lifting lug 31 and the nameplate 32 facilitates the lifting operation of the cargo box 3 by the crane 22. At the same time, the recognition function of the nameplate 32 by the visual module 4 ensures the accurate classification of the cargo box 3.

[0035] The pushing mechanism 5 includes a support frame 51, a rotating assembly 52 and an extrusion assembly 53. The top of the support frame 51 is fixedly connected to a flat plate 511 and an inclined plate 512. The connection between the flat plate 511 and the inclined plate 512 is a rounded design with a certain curvature, which can ensure that the cargo box 3 transitions smoothly between the flat plate 511 and the inclined plate 512. The top of the flat plate 511 and the inclined plate 512 are fixedly connected to guide bars 513. Two groups of guide bars 513 are symmetrically arranged. A weighing module 5111 is arranged on the flat plate 511. The rotating assembly 52 is used to position the cargo box 3 on the top of the flat plate 511 and release the positioning of the cargo box 3 when the cargo box 3 is a defective product. The extrusion assembly 53 is used to push the cargo box 3 of the defective product to the defective product conveyor belt. The design of the pushing mechanism 5 realizes the automatic identification and separation of the cargo box 3 of the defective product, avoids the defective product from flowing into the subsequent process, and improves the accuracy and reliability of the transportation. In addition, the double guide bar 513 design ensures the stability of the cargo box transportation.

[0036] Reference Figures 1-9 The rotating assembly 52 includes a U-shaped rod 521, a transmission member 522, a rotating rod 523, a stabilizing rod 525, and a receiving rod 528. The rotating rod 523 is rotatably mounted on the bottom of the flat plate 511. The opening and closing plate 524 is fixedly connected to the surface of the rotating rod 523. A coil spring 527 is sleeved on the surface of the rotating rod 523. The elastic force of the coil spring 527 drives the opening and closing plate 524 to fit together with the guide bar 513, providing a foundation for subsequent pushing operations. The preload of the coil spring 527 maintains the opening and closing plate 524 in a normally closed state, forming a mechanical self-locking protection, ensuring the reliable positioning of the cargo box 3. The precise control of the rotating assembly 52 ensures that the cargo box 3 can be quickly and accurately released from the position when it is identified as defective.

[0037] Furthermore, the transmission member 522 is symmetrically provided with two groups, and the transmission member 522 includes a fixed frame 5221, a V-shaped frame 5223, a rack 5224 and a gear 5225, wherein a hook 529 is fixedly connected to one of the fixed frames 5221, the fixed frame 5221 is fixedly connected to the U-shaped rod 521, a roller 5222 is rotatably mounted on the fixed frame 5221, the rack 5224 is fixedly connected to the V-shaped frame 5223, the gear 5225 is fixedly mounted on one end of the rotating rod 523, and the gear 5225 is fixedly mounted on the rack 52 24 meshing connection, a slider 5226 is fixedly connected to the rack 5224, a slide groove is provided on the guide bar 513, and the slider 5226 is slidably installed in the slide groove, and an inclined section 5223a and a straight section 5223b are provided on the V-shaped frame 5223, and the roller 5222 rolls along the inclined section 5223a and the straight section 5223b. Through the mutual cooperation of the gear 5225, the rack 5224 and the V-shaped track, accurate action switching can be achieved, and the structural design of the roller 5222 and the slider 5226 effectively reduces movement friction loss.

[0038] Furthermore, one end of the stabilizing rod 525 is fixedly connected to the bottom of the flat plate 511, and the U-shaped rod 521 is sleeved on the surface of the stabilizing rod 525. An auxiliary spring 526 is sleeved on the surface of the stabilizing rod 525. The elastic force of the auxiliary spring 526 drives the U-shaped rod 521 to move downward along the stabilizing rod 525. One end of the receiving rod 528 is fixedly connected to the U-shaped rod 521, and the other end of the receiving rod 528 is provided with a main inclined surface 5281. The guide structure of the stabilizing rod 525 cooperates with the auxiliary spring 526 to realize the automatic reset function, and the inclined transmission design can optimize the force transmission path.

[0039] When in use, the cargo box 3 filled with building materials is conveyed to the inclined plate 512 by the conveyor belt. Under the action of its own gravity, the cargo box 3 slides downward along the inclined plate 512 and moves to the top of the flat plate 511;

[0040] The visual module 4 identifies the nameplate 32 on the cargo box 3 and determines the type of building materials in the cargo box 3. The weighing module 5111 detects the weight of the cargo box 3.

[0041] After detection by the weighing module 5111, if the weight meets the standard weight range of this type of building material, the weighing module 5111 sends a "qualified signal" and feeds the "qualified signal" back to the vision module 4. Under the guidance of the vision module 4, the hook 221 lifts the cargo box 3 through the lifting lug 31, and with the cooperation of the X-axis linear motion module 21 and the Y-axis linear motion module 1, the cargo boxes 3 of the same type are sorted and placed together;

[0042] After detection by the weighing module 5111, if the weight does not meet the standard weight range of this type of building material, the weighing module 5111 sends an "unqualified signal" and feeds the "unqualified signal" back to the visual module 4. Under the guidance of the visual module 4, the hook 221 moves to the hook ring 529 and pulls the U-shaped rod 521 to move upward along the stabilizing rod 525. The auxiliary spring 526 contracts and the elastic force increases under the extrusion of the U-shaped rod 521. The U-shaped rod 521 moves and drives the roller 5222 to move upward synchronously. The roller 5222 first rolls upward along the inclined section 5223a. Under the extrusion of the roller 5222, the slider 5226 on the rack 5224 slides along the slide groove. The rack 5224 and the gear 5225 cooperate with each other to drive the rotating rod 523 to rotate around its own axis. The rotating rod 523 rotates and drives the opening and closing plate 524 to rotate downward synchronously around the axis of the rotating rod 523. The opening and closing plate 524 gradually separates from the guide bar 513, removing the obstruction to the cargo box 3.

[0043] In summary, the present invention can effectively identify the nameplate 32 on the cargo box 3 and determine the type of building materials in the cargo box 3 by setting the visual module 4 and the weighing module 5111. At the same time, the weighing module 5111 is used to detect the weight of the cargo box 3. The weighing module 5111 is pre-stored with a database, which records the standard weight range of each type of building material after packing. After comparing with the standard weight range, the cargo box 3 with defective products whose loading amount deviates from the actual required amount can be effectively identified to avoid incorrect transportation. If there is no deviation after comparison, the cargo boxes 3 with the same type of building materials can be classified and coded together to ensure accuracy. The specific control system and logic programming of this part are existing technologies in the field of intelligence and will not be repeated here.

[0044] Reference Figures 1-11 The extrusion assembly 53 includes a connecting rod 531, a hydraulic cylinder 532, a piston rod 534, a guide tube 535 and a hydraulic component 536. The hydraulic cylinder 532 is fixedly installed at the bottom of the inclined plate 512. A piston 533 is provided in the hydraulic cylinder 532. A sealed sliding guide is formed between the piston 533 and the hydraulic cylinder 532. One end of the piston rod 534 is fixedly connected to one end of the connecting rod 531, and the other end of the piston rod 534 passes through the hydraulic cylinder 532 and is fixedly connected to the piston 533. A secondary inclined surface 5311 is provided on the connecting rod 531, and the main inclined surface 5281 matches the secondary inclined surface 5311. The design of hydraulic drive combined with inclined surface transmission can achieve smooth and efficient pushing force output.

[0045] Furthermore, a movable component 33 is provided on the cargo box 3, and two groups of movable components 33 are symmetrically arranged. The movable component 33 includes a movable block 331, a built-in groove 332 and a guide column 333. The built-in groove 332 is opened on the side of the cargo box 3, and one end of the guide column 333 is fixedly connected to the bottom of the built-in groove 332. The movable block 331 is sleeved on the surface of the guide column 333, and a compression spring 334 is sleeved on the surface of the guide column 333. The elastic force of the compression spring 334 drives the movable block 331 to move in a direction away from the bottom of the built-in groove 332. A trigger slope 3311 and a trigger plane 3312 are provided on the movable block 331. The dual-functional surface design of the movable block 331 can adapt to different pushing conditions, and the buffering structure of the compression spring 334 can effectively reduce the impact loss of the equipment.

[0046] Furthermore, the hydraulic components 536 are symmetrically arranged in two groups, and the hydraulic components 536 include a hydraulic cylinder 2 5361 and a piston rod 2 5363. The hydraulic cylinder 2 5361 is fixedly installed at the bottom of the inclined plate 512. A piston 2 5362 is arranged in the hydraulic cylinder 2 5361. A sealing sliding guide is formed between the piston 2 5362 and the hydraulic cylinder 2 5361. One end of the piston rod 2 5363 is fixedly connected to the positioning plate 5364. The other end of the piston rod 2 5363 passes through the hydraulic cylinder 2 5361 and is fixedly connected to the piston 2 5362. A reset spring 5365 is provided on the surface of the piston rod 2 5363. The elastic force of the reset spring 5365 drives the positioning plate 5364 toward the The hydraulic cylinders 532 and 5361 are fixedly connected via a guide tube 535. The two hydraulic cylinders are symmetrically arranged and hydraulically linked via the guide tube 535 to ensure synchronous movement of the positioning plates 5364 on both sides, eliminating the problem of eccentric loading caused by unilateral force. In addition, the isobaric transmission characteristics of the hydraulic oil in the closed pipeline control the displacement consistency error of the two cylinders within the allowable range of the project. The pre-compression design of the return spring 5365 provides a constant return driving force, so that the piston rod 5363 can be quickly retracted after hydraulic unloading. The spring force and the hydraulic thrust form a complementary relationship, which not only ensures working stability but also improves the cycle operation speed.

[0047] When in use, as the cargo box 3 slides downward along the inclined plate 512 and moves to the top of the flat plate 511, the triggering inclined surface 3311 on the movable block 331 first contacts the positioning plate 5364, and under the pressure of the positioning plate 5364, the movable block 331 slides along the guide column 333 and retracts into the built-in groove 332 (the movable block 331 cannot overcome the elastic force of the return spring 5365 to pull the positioning plate 5364 to move, and the positioning plate 5364 remains stationary). The compression spring 334 contracts and the elastic force increases under the pressure of the movable block 331. When the triggering inclined surface 3311 is separated from the positioning plate 5364, the elastic force of the compression spring 334 is released and drives the movable block 331 to extend outward from the built-in groove 332. At this time, the cargo box 3 and the opening and closing plate 524 conflict with each other.

[0048] The vision module 4 identifies the nameplate 32 on the cargo box 3 and determines the type of building materials in the cargo box 3. The weighing module 5111 detects the weight of the cargo box 3. If the weight is within the standard weight range of the building materials of the same type, the cargo boxes 3 containing the same type of building materials can be sorted and placed together. If the weight is not within the standard weight range of the building materials of the same type, then under the guidance of the vision module 4, the hook 221 moves to the hook ring 529 and pulls the U-shaped rod 521 to move upward along the stabilizing rod 525. The roller 5222 first rolls upward along the inclined section 5223a. Under the pressure of the roller 5222, the opening and closing plate 524 rotates downward around the axis of the rotating rod 523 and separates from the guide bar 513.

[0049] The roller 5222 continues to roll upward along the straight section 5223b. During this process, the positions of the V-shaped frame 5223 and the rack 5224 remain fixed, and the position of the opening and closing plate 524 also remains fixed. When the main inclined surface 5281 on the receiving rod 528 begins to contact the secondary inclined surface 5311, under the pressure of the receiving rod 528, the connecting rod 531 drives the piston rod 1 534 to move into the hydraulic cylinder 1 532. The piston rod 1 534 moves and drives the piston 1 533 to slide synchronously along the hydraulic cylinder 1 532. The piston 1 533 presses the hydraulic oil. Extrusion, under the push of hydraulic oil, piston 2 5362 slides synchronously along hydraulic cylinder 2 5361, and the return spring 5365 contracts and the elastic force increases under the squeezing of piston 2 5362. Piston 2 5362 moves and drives piston rod 2 5363 to extend outward from hydraulic cylinder 2 5361. Piston rod 2 5363 moves and drives the positioning plate 5364 to move synchronously. The positioning plate 5364 conflicts with the trigger plane 3312 of the movable block 331 and pushes the cargo box 3 away from the top of the flat plate 511, so that the cargo box 3 enters the defective product conveyor belt.

[0050] In summary, the present invention can automatically identify and push defective cargo boxes 3 whose weight does not meet the standard due to reasons such as missing or wrong loading to the defective cargo box conveyor, effectively preventing the defective cargo boxes 3 from flowing into the subsequent classification and stacking area, thereby ensuring the accuracy of the packing. In addition, through the mutual cooperation of the rotating component 52 and the extruding component 53, the present invention realizes the positioning, unpositioning and pushing process of the cargo box 3 with a high degree of integration and automation. This design is not only simple and fast to operate, but also improves the accuracy and reliability of the overall conveying process.

[0051] In addition, when transferring the defective cargo box 3 to the defective conveyor belt, the thrust of the positioning plate 5364 is directly used instead of hoisting the defective cargo box 3 onto the defective conveyor belt. This ensures that the defective conveyor belt does not need to be shut down, thereby improving the overall work efficiency (when the cargo box 3 is placed on the conveyor belt by hoisting, the conveyor belt needs to be shut down).

[0052] The working principle of the present invention is as follows: the cargo box 3 loaded with building materials is transported to the inclined plate 512 by the conveyor belt, and the cargo box 3 slides downward along the inclined plate 512 under the action of its own gravity and moves to the top of the flat plate 511. During this process, the triggering inclined surface 3311 on the movable block 331 first contacts the positioning plate 5364, and under the extrusion of the positioning plate 5364, the movable block 331 slides along the guide column 333 and retracts into the built-in groove 332 (the movable block 331 cannot overcome the elastic force of the return spring 5365 to pull the positioning plate 5364 to move, and the positioning plate 5364 remains stationary). The compression spring 334 contracts and the elastic force increases under the extrusion of the movable block 331. When the triggering inclined surface 3311 separates from the positioning plate 5364, the elastic force of the compression spring 334 is released and drives the movable block 331 to extend outward from the built-in groove 332. At this time, the cargo box 3 and the opening and closing plate 524 conflict with each other.

[0053] The visual module 4 identifies the nameplate 32 on the cargo box 3 to determine the type of building materials in the cargo box 3 , and the weighing module 5111 detects the weight of the cargo box 3 .

[0054] After detection by the weighing module 5111, if the weight is within the standard weight range of this type of building material, then under the guidance of the visual module 4, the hook 221 lifts the cargo box 3 through the lifting ear 31, and with the cooperation of the X-axis linear motion module 21 and the Y-axis linear motion module 1, the cargo boxes 3 of the same type are classified and placed together.

[0055] After detection by the weighing module 5111, if the weight does not meet the standard weight range of this type of building material, the hook 221 moves to the hook ring 529 under the guidance of the visual module 4, and pulls the U-shaped rod 521 to move upward along the stabilizing rod 525. The auxiliary spring 526 contracts and the elastic force increases under the extrusion of the U-shaped rod 521. The U-shaped rod 521 moves and drives the roller 5222 to move upward synchronously. The roller 5222 first rolls upward along the inclined section 5223a. Under the extrusion of the roller 5222, the slider 5226 on the rack 5224 slides along the slide groove. The rack 5224 and the gear 5225 cooperate with each other to drive the rotating rod 523 to rotate around its own axis. The rotating rod 523 rotates and drives the opening and closing plate 524 to rotate downward synchronously around the axis of the rotating rod 523. The opening and closing plate 524 gradually separates from the guide bar 513.

[0056] The roller 5222 continues to roll upward along the straight section 5223b. During this process, the positions of the V-shaped frame 5223 and the rack 5224 remain fixed, and the position of the opening and closing plate 524 also remains fixed. When the main inclined surface 5281 on the receiving rod 528 begins to contact the secondary inclined surface 5311, under the pressure of the receiving rod 528, the connecting rod 531 drives the piston rod 1 534 to move into the hydraulic cylinder 1 532. The piston rod 1 534 moves and drives the piston 1 533 to slide synchronously along the hydraulic cylinder 1 532. The piston 1 533 presses the hydraulic oil. Extrusion, under the push of hydraulic oil, piston 2 5362 slides synchronously along hydraulic cylinder 2 5361, and the return spring 5365 contracts and the elastic force increases under the squeezing of piston 2 5362. Piston 2 5362 moves and drives piston rod 2 5363 to extend outward from hydraulic cylinder 2 5361. Piston rod 2 5363 moves and drives the positioning plate 5364 to move synchronously. The positioning plate 5364 conflicts with the trigger plane 3312 of the movable block 331 and pushes the cargo box 3 away from the top of the flat plate 511, so that the cargo box 3 enters the defective product conveyor belt.

[0057] Afterwards, the hook 221 is separated from the hook ring 529, the elastic force of the auxiliary spring 526 and the coil spring 527 is released, the U-shaped rod 521 moves downward along the stabilizing rod 525 and returns to the initial position, the opening and closing plate 524 rotates upward around the axis of the rotating rod 523 and returns to the initial position, the elastic force of the reset spring 5365 is released and drives the positioning plate 5364 and the piston two 5362 to return to the initial position, and the piston two 5362 moves while pushing the piston one 533 and the connecting rod 531 back to the initial position through the hydraulic oil.
