[0002] In the brewing industry, large quantities of grain are usually required as raw materials for brewing.

[0031] The following combination Figure 1-Figure 3 , through specific embodiments and application scenarios, a material conveying device provided by an embodiment of the present utility model is described in detail.

[0032] like Figure 1 and Figure 2 As shown, the present invention provides a material conveying device, comprising: a vehicle body 1, a track 2, a controller, a first conveying mechanism 3 and a second conveying mechanism 4. A moving mechanism 11 is installed on the lower side of the vehicle body 1, and the moving mechanism 11 travels on the track 2.

[0033] The first conveying mechanism 3 and the second conveying mechanism 4 are symmetrically installed at opposite ends of the vehicle body 1 along the transverse direction of the vehicle body 1. The first conveying mechanism 3 and the second conveying mechanism 4 are used to convey materials from the previous workstation to the vehicle body 1.

[0034] The vehicle body 1 is equipped with a through-beam sensor 12. The through-beam sensor 12 is used to detect the position of the material relative to the vehicle body 1. The through-beam sensor 12 is communicatively connected to a controller, which is in communication with the moving mechanism 11, the first conveying mechanism 3, and the second conveying mechanism 4.

[0035] Specifically, the material conveying device provided by the present invention can realize the transportation of large and heavy objects such as grains and mash, reduce manual participation, and improve the efficiency of material conveying.

[0036] like Figure 1 As shown, there are two tracks 2. The two tracks 2 are arranged in parallel. The vehicle body 1 travels on the two tracks 2 via a moving mechanism 11. The vehicle body 1 can be an intelligent mobile transport vehicle that can travel along the tracks 2, such as an RGV vehicle, which is not specifically limited to this.

[0037] like Figure 2 As shown, the first conveying mechanism 3 and the second conveying mechanism 4 are both installed on the top of the vehicle body 1 and symmetrically installed at both ends of the vehicle body 1 along the transverse direction of the vehicle body 1. The conveying directions of the first conveying mechanism 3 and the second conveying mechanism 4 are both consistent with the transverse direction of the vehicle body 1.

[0038] Figure 1 and Figure 2 The stationary position of the vehicle body 1 shown is the initial position of the vehicle body 1. In some application scenarios, when the vehicle body 1 is stationary in the initial position, the first conveying mechanism 3 and the second conveying mechanism 4 just correspond to the conveyor line of the previous workstation, and the material is directly conveyed from the conveyor line of the previous workstation to the first conveying mechanism 3 and the second conveying mechanism 4, and then the first conveying mechanism 3 and the second conveying mechanism 4 convey the material to the middle area on the top of the vehicle body 1.

[0039] Specifically, if Figure 1As shown, the through-beam sensor 12 is mounted on the top of the vehicle body 1. The through-beam sensor 12 includes a transmitter 121 and a receiver 122.

[0040] The controller is installed inside the vehicle body 1. The transmitter 121 transmits an infrared signal or a laser signal to the receiver 122. The processing element of the through-beam sensor 12 can detect the position information of the material based on the change in the signal received by the receiver 122. When the through-beam sensor 12 detects the presence of material, the controller controls the first conveying mechanism 3 and the second conveying mechanism 4 to start at the same time and maintain the same operating speed, so as to gradually transfer the material from the outer edge of the vehicle body 1 to the central area of ​​the vehicle body 1 through the first conveying mechanism 3 and the second conveying mechanism 4. The through-beam sensor 12 sends the position information of the material to the controller in real time, and the controller determines whether the material has reached the preset position based on the position information of the material. When the material reaches the preset position, the controller controls the first conveying mechanism 3 and the second conveying mechanism 4 to stop running, and immediately starts the moving mechanism 11 to make the vehicle body 1 move along the track 2, thereby transporting the material to the next workstation.

[0041] like Figure 1 As shown, the transmitter 121 and receiver 122 are arranged at an oblique angle relative to the vehicle body 1 to increase the detection range of the through-beam sensor 12. Optionally, two through-beam sensors 12 are provided. Two through-beam sensors 12 can ensure that the detection range covers the entire top area of ​​the vehicle body 1, thereby ensuring sensitivity for material detection. Of course, the number of through-beam sensors 12 can also be three, four, or six, etc., without specific limitation.

[0042] The utility model provides a material conveying device, in which a through-beam sensor 12 is used to detect the position information of the material relative to the vehicle body 1 in real time, and the first conveying mechanism 3 and the second conveying mechanism 4 are used to convey the material of the previous workstation to the middle area on the top of the vehicle body 1 to ensure the balance of the vehicle body 1; when the material is conveyed to the middle area on the top of the vehicle body 1, the controller controls the first conveying mechanism 3 and the second conveying mechanism 4 to stop working, and controls the moving mechanism 11 to operate at the same time, so that the material moves with the vehicle body 1 to the end point of the track 2, and the material is conveyed from the previous workstation to the next workstation through the material conveying device, which reduces manual auxiliary operations, has a high degree of automation, and improves the material conveying efficiency.

[0043] In some embodiments, as Figure 3 As shown, the track 2 includes a track body 21, an embedded plate 22, a leveling mechanism 23, and a cast body. The movable mechanism 11 is movably mounted on the track body 21. The embedded plate 22 is embedded horizontally below the ground. The leveling mechanism 23 is connected to the top surface of the embedded plate 22. The track body 21 is fixedly mounted on the leveling mechanism 23. The leveling mechanism 23 is used to adjust the angle of the track body 21 relative to the horizontal plane. The cast body is used to cast the leveling mechanism 23 after the leveling mechanism 23 has leveled the track body 21.

[0044] Specifically, the embedded plate 22 is embedded in the ground horizontally. During construction, the position of the embedded plate 22 is fixed by a support frame to ensure that the embedded plate 22 is parallel to the horizontal plane, and then concrete is poured between the support frame and the embedded plate 22 to ensure the stability of the embedded plate 22.

[0045] like Figure 3 As shown, the leveling mechanism 23 is located above the embedded plate 22. The bottom of the leveling mechanism 23 is fixedly connected to the embedded plate 22 to provide support for the leveling mechanism 23 through the embedded plate 22. The rail body 21 has a sliding groove extending along its axial direction, and the moving mechanism 11 travels along the sliding groove. The rail body 21 is fixedly installed on the top of the leveling mechanism 23 so that the inclination angle of the rail body 21 can be fine-tuned by the leveling mechanism 23, thereby ensuring that the rail body 21 can be installed parallel to the ground. After the rail body 21 is leveled, a casting body is cast at the bottom of the embedded plate 22, the leveling mechanism 23 and the rail body 21 to ensure the stability of the entire track 2. Compared with directly installing the rail body 21 on the embedded plate 22, this method can accurately adjust the installation height and angle of the rail body 21, reducing construction errors.

[0046] Under the condition that the rail body 21 is sufficiently flat, the vehicle body 1 can be ensured to travel smoothly on the rail body 21 without overturning when the material is heavy, which has good reliability and improves the efficiency of material transportation.

[0047] In some embodiments, as Figure 3 As shown, the leveling mechanism 23 includes a leveling plate 231, a screw 232, a positioning nut 233, and a locking nut 234. The rail body 21 is fixed to the leveling plate 231. The screw 232 is vertically mounted on the top surface of the embedded plate 22. The positioning nut 233, the leveling plate 231, and the locking nut 234 are respectively mounted on the screw 232. The leveling plate 231 is sandwiched between the positioning nut 233 and the locking nut 234. The locking nut 234 is used to lock the leveling plate 231 to the positioning nut 233.

[0048] Specifically, multiple sets of screws 232, positioning nuts 233, and locking nuts 234 are provided. These sets are spaced apart around the screed plate 231 to allow for adjustment of the angle of the screed plate 231 from multiple angles. The rail body 21 can be welded to the screed plate 231. Taking one set of screws 232, positioning nuts, and locking nuts 234 as an example, the screws 232 are arranged vertically, with their bottom ends welded to the top surface of the embedded plate 22. The positioning nuts 233 are fitted over the screws 232. During leveling, the positioning nuts 233 are rotated until the required installation height is met, depending on the installation elevation of the screed plate 231. The screed plate 231 is then fitted over the screws 232, followed by the locking nuts 234. The locking nuts 234 are then tightened to lock the screed plate 231 to the positioning nuts 233. The installation height and angle of the leveling plate 231 can be fine-tuned according to actual needs through multiple sets of screws 232, positioning nuts 233 and locking nuts 234, thereby improving the flatness of the rail body 21, ensuring the stability of the vehicle body 1 during the transportation of materials, preventing the vehicle body 1 from overturning due to excessive weight of materials, and thereby improving the efficiency of material transportation.

[0049] Specifically, the moving mechanism 11 includes at least one set of moving components. The moving components can be provided in two sets. Both sets of moving components are installed on the lower side of the vehicle body 1 and are spaced apart along the travel direction of the vehicle body 1 to ensure the smooth travel of the vehicle body 1.

[0050] Take one set of mobile components as an example, Figure 3 As shown, the moving assembly includes a dual-axis motor 111 and two moving wheels 112. The dual-axis motor 111 is fixedly mounted on the lower side of the vehicle body 1. The two moving wheels 112 are located on the lower side of the vehicle body 1 and are symmetrically arranged at opposite ends of the vehicle body 1 along the travel direction of the vehicle body 1. The two moving wheels 112 are respectively slidably arranged on the two rail bodies 21. The two driving ends of the dual-axis motor 111 are respectively connected to the wheel axles of the two moving wheels 112 to simultaneously drive the two moving wheels 112 to maintain the same rotational speed and slide along the two rail bodies 21.

[0051] Optionally, the dual-axis motor 111 may be a dual-axis stepping motor or a dual-axis servo motor.

[0052] In some embodiments, as Figure 3 As shown, the first conveying mechanism 3 includes: a chain 31, a driving sprocket 32, two driven sprockets 33 and two anti-slip rollers 34. The driving sprocket 32, the driven sprocket 33 and the anti-slip rollers 34 are respectively installed on the vehicle body 1.

[0053] The two driven sprockets 33 are symmetrically arranged at opposite ends of the vehicle body 1 along the travel direction of the vehicle body 1. The driving sprocket 32 ​​is located between the two driven sprockets 33. The driving sprocket 32 ​​is installed at a lower height than the two driven sprockets 33. Two anti-slip rollers 34 are arranged on opposite sides of the driving sprocket 32. The driving sprocket 32 ​​is installed at a higher height than the anti-slip rollers 34. The chain 31 is sequentially mounted on the two anti-slip rollers 34, which are used to tension the chain 31. The driving sprocket 32 ​​and the two driven sprockets 33 are respectively engaged with the chain 31.

[0054] Specifically, if Figure 3 As shown, two driven sprockets 33 are mounted at the same height at each end of the vehicle body 1. The two driven sprockets 33 are mounted at a higher height than the driving sprocket 32. The driving sprocket 32 ​​and the two driven sprockets 33 engage with the chain 31. The driving sprocket 32 ​​provides the driving force to move the chain 31, while the two driven sprockets 33 guide the chain 31 in lateral motion along the vehicle body 1, thereby transporting material above the chain 31 to the next workstation.

[0055] The driving sprocket 32 ​​is located between the two driven sprockets 33. Optionally, the driving sprocket 32 ​​is spaced the same distance from the two driven sprockets 33 to prevent the driving sprockets 32 and the driven sprockets 33 from interfering with the transmission of the chain 31 due to the excessive distance between them. One of the anti-slip rollers 34 is rotatably mounted between the driving sprocket 32 ​​and one of the driven sprockets 33, while the other anti-slip roller 34 is rotatably mounted between the driving sprocket 32 ​​and the other of the driven sprockets 33. The driving sprocket 32, the two anti-slip rollers 34, and the two driven sprockets 33 form a transmission path, along which the chain 31 is arranged. Each anti-slip roller 34 is positioned adjacent to the driving sprocket 32 ​​but does not contact it. Each anti-slip roller 34 is mounted at a lower height than the driving sprocket 32 ​​and serves to tighten the chain 31 when the driving sprocket 32 ​​switches its rotation direction, thereby preventing the chain 31 from decoupling from the driving sprocket 32.

[0056] For example, Figure 2As shown, materials need to be conveyed from the left side of the vehicle body 1 to the middle area on top of the vehicle body 1. Initially, the driving sprocket 32 ​​is activated to rotate counterclockwise. During this sudden counterclockwise rotation of the driving sprocket 32, the anti-slip roller 34 located to the right of the driving sprocket 32 ​​tensions the chain 31 segment located at the driving sprocket 32, ensuring that the chain 31 maintains sufficient tension and does not become dislodged. When materials need to be conveyed from the right side of the vehicle body 1 to the middle area on top of the vehicle body 1, the rotation direction of the driving sprocket 32 ​​is instantly switched to clockwise. At this time, the anti-slip roller 34 located to the left of the driving sprocket 32 ​​tensions the chain 31 segment located at the driving sprocket 32, ensuring that the chain 31 maintains sufficient tension and does not become dislodged, maintaining constant engagement with the driving sprocket 32. During the frequent rotational switching of the driving sprocket 32, the chain 31 and the driving sprocket 32 ​​remain in constant engagement, thereby improving the conveying efficiency of the material conveying system.

[0057] The first conveying mechanism 3 provided by the present invention has a driving sprocket 32 ​​for driving the chain 31 to move, and two driven sprockets 33 are rotatably installed at both ends of the vehicle body 1 for guiding the chain 31 to be transmitted laterally along the vehicle body 1 so as to convey the material above the chain 31 to a preset position of the vehicle body 1, and two anti-slip rollers 34 are arranged on opposite sides of the driving sprocket 32, and the installation height of the driving sprocket 32 ​​is higher than the anti-slip rollers 34. When the driving sprocket 32 ​​switches the rotation direction, the anti-slip roller 34 located downstream in the transmission direction of the chain 31 can always tension the chain 31 section at the driving sprocket 32 ​​to ensure that the chain 31 has sufficient tension and will not be dislocated. The chain 31 and the driving sprocket 32 ​​always remain in a meshing state, thereby improving the conveying efficiency of the material conveying device.

[0058] Furthermore, in some embodiments, Figure 3 As shown, the first conveying mechanism 3 further includes a tensioning wheel 35. The tensioning wheel 35 is located between the anti-slip roller 34 on one side of the driving sprocket 32 ​​and the driven sprocket 33. The chain 31 is mounted on the tensioning wheel 35, and the tensioning wheel 35 is movably mounted on the vehicle body 1 to adjust the tension of the chain 31.

[0059] Specifically, the tensioning wheel 35 is arranged on the transmission path between the two adjacent anti-slip rollers 34 and the driven sprocket 33. The chain 31 is mounted on the tensioning wheel 35. As the tensioning wheel 35 moves, the tension of the chain 31 changes. Optionally, the moving direction of the tensioning wheel 35 can be consistent with the conveying direction of the material, or can be perpendicular to the conveying direction of the material. For example, when the moving direction of the tensioning wheel 35 is consistent with the conveying direction of the material, as in Figure 3As shown, when the tensioning wheel 35 moves in the direction close to the driven sprocket 33 on the left, the tension of the chain 31 decreases. When the tensioning wheel 35 moves in the direction close to the driven sprocket 33 on the right, the tension of the chain 31 increases. For another example, when the moving direction of the tensioning wheel 35 is perpendicular to the conveying direction of the material, when the tensioning wheel 35 moves in the direction close to the anti-slip roller 34, the tension of the chain 31 decreases. When the tensioning wheel 35 moves in the direction close to the driven sprocket 33, the tension of the chain 31 increases. Therefore, the user can control the position of the tensioning wheel 35 relative to the vehicle body 1 according to actual needs, thereby adjusting the tension of the chain 31 and improving the material conveying efficiency.

[0060] Optionally, the tensioning wheel 35 is gearless to ensure the tensioning effect of the tensioning wheel 35 on the chain 31.

[0061] Furthermore, the first conveying mechanism 3 also includes a linear drive mechanism. Figure 3 As shown, the tensioning pulley 35 includes a connecting shaft 351 and a wheel body 352. The chain 31 is mounted on the wheel body 352. The wheel body 352 is rotatably mounted on the connecting shaft 351. The connecting shaft 351 is configured to pass through the strip-shaped hole 13 in the vehicle body 1 and is in transmission connection with a linear drive mechanism, which is configured to drive the connecting shaft 351 along the extension direction of the strip-shaped hole 13.

[0062] The wheel body 352 is rotatably mounted on the connecting shaft 351 via a bearing. Figure 3 As shown, the vehicle body 1 is provided with a strip-shaped hole 13. Optionally, the extension direction of the strip-shaped hole 13 is consistent with the material conveying direction. Optionally, the extension direction of the strip-shaped hole 13 is perpendicular to the material conveying direction. A linear drive mechanism is mounted on the vehicle body 1. The driving end of the linear drive mechanism is in transmission connection with the connecting shaft 351 to drive the connecting shaft 351 to move along the extension direction of the strip-shaped hole 13. The wheel body 352 moves along with the connecting shaft 351, thereby adjusting the tension of the chain 31. Optionally, the linear drive mechanism may be a screw drive mechanism.

[0063] The specific structure of the second conveying mechanism 4 is the same as that of the first conveying mechanism 3 , and details can be referred to the specific embodiment of the first conveying mechanism 3 , which will not be described again here.

[0064] like Figure 1 As shown, a laser rangefinder 14 is installed on the front side of the vehicle body 1. The laser rangefinder 14 is connected to the controller for communication, and the controller is connected to the moving mechanism 11, the first conveying mechanism 3 and the second conveying mechanism 4 for communication.

[0065] Specifically, if Figure 1 and Figure 2As shown, a reflector 141 is installed at the end of track 2. The laser rangefinder 14 emits a pulsed laser toward the reflector 141. The receiver of the laser rangefinder 14 receives the pulse signal. The processing element of the laser rangefinder 14 calculates the distance between the vehicle body 1 and the end of track 2 based on the signal strength and time received by the receiver. The laser rangefinder 14 sends the detection information to the controller. The controller determines whether the vehicle body 1 has reached the end position of track 2 based on the detection information of the laser rangefinder 14. When track 2 reaches the end position, the controller controls the moving mechanism 11 to stop; at the same time, the controller controls the first conveying mechanism 3 and the second conveying mechanism 4 to start operation simultaneously, and the first conveying mechanism 3 and the second conveying mechanism 4 convey the material to the outer edge of the vehicle body 1.

[0066] When the vehicle body 1 stops at the end position of the track 2, the first conveying mechanism 3 and the second conveying mechanism 4 just correspond to the two transport lines of the next workstation, so that the first conveying mechanism 3 and the second conveying mechanism 4 can directly transport the material to the next workstation, thereby improving the degree of automation of the material conveying device.

[0067] Based on the position detection of the material on the vehicle body 1 by the through-beam sensor 12, when the material is separated from the vehicle body 1, the controller controls the first conveying mechanism 3 and the second conveying mechanism 4, and at the same time controls the moving mechanism 11 to start running. The vehicle body 1 moves along the track 2 to the initial position to receive the material, and this process is repeated to realize the automatic conveying of the material.

[0068] Finally, it should be noted that 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 do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
