Description

Technical Field

[0001] The present invention relates to the technical field of automatic guided vehicles, in particular to a remote-controlled automatic transfer vehicle for transporting zinc-aluminum-silicon-magnesium-chromium alloy products. Background Art

[0002] An automated guided vehicle (AGV) is an unmanned automated vehicle that travels along a planned path, is battery-powered, and is equipped with safety protection and various auxiliary mechanisms. It has automatic guidance devices such as magnetic strips, tracks, or lasers. An AGV system is usually composed of multiple AGVs, a control computer, navigation equipment, charging equipment, and peripheral accessories. Its main working principle is that under the monitoring and task scheduling of the control computer, the AGV can accurately follow the prescribed path.

[0003] When an automated guided vehicle is transporting alloy products, if it encounters a sudden obstacle or worker on its route, in order to avoid damage caused by collision, the automated guided vehicle will trigger an emergency stop. The emergency stop will cause the alloy products to slide on the automated guided vehicle platform. In order to facilitate the sliding and placing of alloy products on the automated guided vehicle platform, protective interception mechanisms are often not installed around the alloy products. As a result, when the automated guided vehicle stops suddenly, the alloy products will slide, and in severe cases, they will directly slide off the automated guided vehicle.

[0004] How to prevent alloy products from excessively sliding on the guided vehicle platform and how to reset the alloy products after sliding is a technical research and development direction for automatic guided vehicles. To this end, the present invention provides a remote-controlled automatic transfer vehicle for transporting zinc-aluminum-silicon-magnesium-chromium alloy products. Summary of the Invention

When the trolley is stationary, move the alloy product onto the trolley, or slide the alloy product off the trolley. The cap assemblies will have minimal frictional resistance to the alloy product. When the trolley suddenly stops during transportation, the alloy product will slide due to inertia. The multiple cap assemblies in the sliding direction of the alloy product will automatically increase the friction resistance to the alloy product, thereby intercepting the sliding alloy product.

[0017] 2. The friction between the cap assembly and the alloy product comes from the contact friction between the triangular closed-loop belt and the alloy product. After the alloy product is intercepted by the cap assembly, the intercepted cap assembly is triggered to automatically rotate horizontally, ensuring that the conveying direction of the triangular closed-loop belt on the cap assembly is the reset direction of the alloy product. Then the corresponding multiple triangular closed-loop belts jointly convey the alloy product. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the roller gear 25 is engaged with the inner worm 27 by setting a gear. The upper surface of the triangular closed-loop belt 23 prevents the object from sliding on the platform main board 3 by contacting the object.

[0043] Combine Figure 10 、 Figure 11 and Figure 12 It is understood that the internal device 19 includes a hair storage device 29 for driving the long rod gear 28, a switch assembly 32 for hindering the rotation of the long rod gear 28, a regulating frame 33 for supporting the hair storage device 29 and the switch assembly 32, an L-shaped follower rod 30 with one end fixed on the pile 26, a hair pressing frame 31 sliding through a square hole opened in the regulating frame 33, and a pull rod 34 for pulling down the switch assembly 32. The hair storage device 29 collects the power of the hair pressing frame 31 when it rises and presses, and when the switch assembly 32 no longer hinders the rotation of the long rod gear 28, the ... the hair storage device 29 collects the power of the hair pressing frame 31 when it rises and presses, and the hair storage device 29 collects the power of the hair pressing frame 31 when it rises and presses, and the hair storage device 29 collects the power of the hair pressing frame 31 when it rises and presses, and the hair storage device 29 The device 29 releases power to drive the long rod gear 28 to rotate. The bottom end of the pressing frame 31 is inserted into the annular groove opened on the inner side wall of the L-shaped support ring 21 by setting a ring cylinder. The other end of the L-shaped following rod 30 is slidably inserted into the through hole opened on the regulating frame 33 so that the regulating frame 33 can rotate horizontally with the pile column 26. The bottom end of the regulating frame 33 is movably connected to the seat cylinder set on the ring plate platform 6 by setting a cylinder, and the pulling rod 34 passes through the middle of the seat cylinder. Two symmetrical arc plates are set on the pile column 26, and the L-shaped following rod 30 is fixed on the arc plate of the pile column 26.

[0044] Attachment Figure 13The power storage device 29 is an integrated component of the prior art power storage and release. The power storage device 29 includes a cylindrical gear 39, a spring 40, a pressure shaft 41, a flat worm 42, a range-extending gear 43, a range-extending shaft 44 and a one-way bearing 45. Specifically, a row of teeth is provided on the pressure frame 31 to engage with a gear fixed at one end of the range-extending shaft 44. The rise of the pressure frame 31 causes the range-extending shaft 44 to rotate, and then the range-extending gear 43 is driven to rotate through the one-way bearing 45. The design of the one-way bearing 45 takes into account the smooth descent and reset of the pressure frame 31. The end of the flat worm 42 is engaged with the gear fixed at one end of the range-extending shaft 44. A gear is provided on the inside to engage with the range-extending gear 43 for transmission, and then the range-extending gear 43 transmits the flat worm 42. The rotation of the flat worm 42 causes the fixed gear on the pressure shaft 41 to rotate. The rotation of the pressure shaft 41 causes the mainspring 40 to contract and store force, thereby driving the external cylindrical gear 39 to rotate. Once the long-rod gear 28 can rotate, the cylindrical gear 39 will transmit the long-rod gear 28. In addition, a star-shaped plate frame is fixed on the lower surface of the cylindrical gear 39, and the pressure shaft 41 and the star-shaped plate frame are in a state of movable socket connection, so that the cylindrical gear 39 is supported and limited.

[0045] The switch assembly 32 includes a recessed seat frame 38 fixed to the regulating frame 33, a folded column 36 that slides through a square hole opened in the recessed seat frame 38, a spring 37 cushioned between the folded column 36 and the recessed seat frame 38, and a neck shaft 35 that is movably sleeved in a circular hole opened in the recessed seat frame 38. Gears are provided at both ends of the neck shaft 35. The gear at one end of the neck shaft 35 is engaged with the long rod gear 28 for transmission, and the gear at the other end of the neck shaft 35 is positioned by being sunk into a gear groove opened in the folded column 36. The pull rod 34 is distributed at the lower axial position of the pile column 26, and the pull rod 34 is movably sleeved in a through hole opened in the folded column 36. Figure 9 and Figure 10 It is understood that there is an inner device 19 distributed just below the cap assembly 18. After the cap assembly 18 is pressed by the object above, the cap assembly 18 drops a short distance, but does not affect the inner device 19 below, because in terms of the lifting relationship, only the L-shaped follower rod 30 and the pile column 26 are fixedly connected, and the lifting of the cap assembly 18 drives the L-shaped follower rod 30, and the L-shaped follower rod 30 and the regulating frame 33 are in a sliding plug-in state, so the inner device 19 does not rise or fall, but after the cap assembly 18 is driven by the integrated worm 16, the cap assembly 18 rotates back and causes the inner device 19 below to rotate, because the cap assembly 18 drives the lower L-shaped follower rod 30 to rotate, which in turn causes the main body of the inner device 19 to rotate, the pressing frame 31 and the L support ring 21 are in a state of movable socketing, and the pulling rod 34 and the folding column 36 are also in a state of movable socketing. Further analysis shows that the regulating frame 33 and the seat cylinder on the lower ring plate platform 6 are in a state of movable socketing, so the regulating frame 33 will not rise or fall, but can rotate in place. For further reference Figure 10The pull rod 34 will pull down the folding column 36, and then the folding column 36 and the gear below the neck shaft 35 will be separated, and the neck shaft 35 can rotate freely. Once the pull rod 34 is no longer pulled down, the spring 37 pushes the folding column 36 to rise, and then the folding column 36 blocks the neck shaft 35, and the gear above the neck shaft 35 blocks the long rod gear 28, and the long rod gear 28 cannot rotate.

[0046] The double-control frame 7 includes a card group 46 and a rack 47. The pull rod 34 passes through the through hole opened on the rack 47, and the rack 47 presses down the disc set at the bottom end of the pull rod 34. The card group 46 includes a restraining plate 53 fixed on the rack 47, a card 51 plugged into one end of the restraining plate 53, and a spring 52 supported between the card 51 and the restraining plate 53. A block is provided on the restraining plate 53 to limit the telescopic range of the card 51. A ratchet is fixed on the gear coupling 17, and a tip is provided on the card 51 to limit the one-way rotation of the gear coupling 17. Refer to the attached Figure 16 It is understood that the rise of the restraining plate 53 will cause the card plate 51 to rise, and then the card plate 51 will block the ratchet, and the ratchet can only rotate clockwise. The restraining plate 53 resets and drives the card plate 51 to fall. After the card plate 51 and the ratchet are separated, the ratchet can rotate counterclockwise.

[0047] The pressing device 8 includes an integrated disk 49 fixedly connected to the rack 47, a needle shaft 48 fixed in the middle of one side of the integrated disk 49, and a speed limiting valve 50 connected to the other side of the integrated disk 49. The middle part of the lower bottom surface of the heavy disk 10 is provided with a round convex seat to support the needle shaft 48. The heavy disk 10 controls the round convex seat and the needle shaft 48 to separate by translation, so that the needle shaft 48 can rise quickly. The heavy disk 10 drives the round convex seat to reset, and the round convex seat pushes the needle shaft 48 down. The speed limiting valve 50 blocks it to slowly reset the needle shaft 48. Figure 15 The speed limiting valve 50 is a conventional air valve, which is used to control the needle shaft 48 to rise quickly and fall slowly.

[0048] The pressing unit 13 includes a cross 55 and a supporting square column 56 fixed on the heavy disk 10, a J-shaped frame 59 sliding on the supporting square column 56, a second shaft gear 60 with one end movably sleeved in a through hole opened on the J-shaped frame 59, a first shaft gear 57 with one end movably sleeved in a through hole opened on the cross 55, a support shaft 54 for establishing a transmission between the ring gear 14 and the first shaft gear 57, an L-shaped guide rod 61 fixed on the supporting square column 56, and a long spring 58 sleeved on the L-shaped guide rod 61, the long spring 58 is supported between the J-shaped frame 59 and the disc body set at the end of the L-shaped guide rod 61, the displacement sensor 9 is fixed on the J-shaped frame 59, and the support shaft 54 is movable. The movable sleeve is connected to the through hole opened on the cross 55, one end of the support shaft 54 is meshed with the ring gear 14 through a fixed gear, and the other end is meshed with the bevel gear set at the end of the first shaft gear 57 by setting a bevel gear. The ring gear 14 is partially inserted into the arc-shaped slide groove opened on the cross 55, and the other end of the first shaft gear 57 and the other end of the second shaft gear 60 are meshed for transmission. A branch gear 171 is provided at the end of the gear coupling 17, and the second shaft gear 60 is meshed with the branch gear 171 by axial movement. One end of the J-shaped frame 59 contacts the edge side wall of the heavy plate 10, and the support square column 56 slides through the ridge hole opened on the J-shaped frame 59. Figure 17 and Figure 18 Understand the position of the displacement sensor 9. When the heavy plate 10 moves in any direction, the J-frame 59 in the moving direction will be caused to move, and then detected by the displacement sensor 9 installed on the J-frame 59. In this way, the translation direction of the heavy plate 10 is monitored by multiple displacement sensors 9 arranged in a ring around the heavy plate 10. That is, when the trolley suddenly brakes, the direction in which the items above the trolley move due to inertia. After determining the translation direction of the items, the cap assembly 18 is driven to rotate horizontally, and the conveying direction of the triangular closed-loop belt 23 is opposite to the translation direction of the items. In this way, the conveying of the triangular closed-loop belt 23 will cause the items to reset and translate, and the items will return to the upper middle position of the trolley.

[0049] The main functional process of the present invention is: after the alloy product is placed on the trolley, the trolley moves under the control of the system interruption. If an obstacle or a staff member suddenly appears in front of the trolley, the trolley will automatically stop suddenly. Due to inertia, the alloy product on the trolley will move horizontally. A large number of cap components 18 are arranged around the alloy product to hinder the translation of the alloy product through contact friction. After the alloy product is transported to the trolley, or slid and pushed away on the trolley, the friction resistance of the cap component 18 to the alloy product is minimal, which is convenient for taking and placing the alloy product. However, if the trolley suddenly stops during transportation, the cap component 18 will automatically increase the friction resistance to the alloy product. This prevents the alloy products from slipping off the trolley. The principle of the cap assembly 18 enhancing friction is further analyzed: during the trolley conveying process, the internal ring gear 14 continues to rotate. Once the trolley stops suddenly, the heavy plate 10 will translate due to inertia. The heavy plate 10 pushes the J-shaped frame 59, and the J-shaped frame 59 drives the second shaft gear 60 to translate. The second shaft gear 60 and the corresponding branch gear 171 establish meshing. The ring gear 14 drives the support shaft 54, and then drives the second shaft gear 60 through the first shaft gear 57. Next, the gear coupling 17 is driven to rotate through the branch gear 171, which causes the row of L-shaped support rings 21 on one side to rise. Figure 8 The rise of the L-shaped support ring 21 in the middle will cause the compression spring 20 to contract, thereby providing greater elastic force to the cap assembly 18. When the alloy product slides over, the portion of the cap assembly 18 protruding above the platform mainboard 3 will be pressed down. After the cap assembly 18 increases the pressure from below, it will be difficult for the cap assembly 18 to descend, thereby providing stronger friction resistance to the alloy product passing over. After the alloy product slides, it has deviated from the middle position of the trolley. The alloy product needs to be returned to the middle position above the trolley to prevent the alloy product from sliding directly off the trolley when it accidentally slides next time. Specifically, a heavy plate 10 for detecting inertia is provided in the trolley. The heavy plate 10 will also slide when the trolley stops suddenly. The moving directions of the heavy plate 10 and the alloy product are the same. The translation direction of the heavy plate 10 is detected and determined by multiple displacement sensors 9 arranged around the heavy plate 10, and the information is transmitted to the trolley host terminal. The host terminal then controls the cap assembly 18 to rotate horizontally by controlling the integrated worm 16. That is, after the alloy product slides and stops above the trolley, multiple cap assemblies 18 in the area corresponding to the sliding direction of the alloy product automatically rotate horizontally to ensure that the subsequent transportation of the triangular closed-loop belt 23 will drive the alloy product to smoothly reverse and reset.

[0050] As mentioned before, the rise of the L support ring 21 causes the compression spring 20 to retract. At the same time, the rise of the L support ring 21 also drives the hair pressing frame 31. During the rising process of the hair pressing frame 31, the hair storage device 29 collects power. At this time, the long rod gear 28 cannot rotate because the heavy plate 10 at the source has translated due to inertia. Figure 15The heavy plate 10 in the middle moves horizontally to drive the round convex seat. After the round convex seat and the needle shaft 48 are separated, the needle shaft 48 below and the integrated plate 49 rise synchronously for a short distance. The integrated plate 49 drives the rack 47. After the rack 47 rises, the controlled pull rod 34 is no longer pulled down. As mentioned before, Figure 10 The pull rod 34 in the middle no longer pulls down the folding column 36, and the folding column 36 will rise to block the neck shaft 35, and then the neck shaft 35 limits the rotation of the long rod gear 28, so that the power is accumulated in the hair storage device 29. When the trolley stops suddenly, the heavy plate 10 automatically resets, and the corresponding round convex seat presses the needle shaft 48 again, and the needle shaft 48 resets and descends. The corresponding needle shaft 48 descends Figure 10 The folded column 36 in the middle descends, and the neck shaft 35 is no longer blocked, and the long rod gear 28 is free to move slowly. At this time, the power accumulated in the hair storage device 29 is released, driving the long rod gear 28 to rotate, and then driving the roller gear 25 through the inner worm 27. The rotation of the roller gear 25 causes the triangular closed-loop belt 23 to transport, and then the alloy product is driven to reset and move through contact friction.

[0051] Continuing to analyze the previous paragraph, during the conveying stage of the triangular closed-loop belt 23, strong friction is maintained between the triangular closed-loop belt 23 and the alloy product, because the L support ring 21 does not fall after rising, and the compression spring 20 is in a compressed state, that is, the gear coupling 17 does not reset and flip after rotating, because the ratchet on the gear coupling 17 is blocked by the rising card group 46, and the gear coupling 17 cannot reset and flip. Although the rack 47, the integrated disk 49 and the needle shaft 48 fall synchronously, there is a sequence mechanism here, that is, the timing when the card group 46 is completely separated from the gear coupling 17 is one step slower than the timing when the neck shaft 35 and the folding column 36 are separated. Therefore, during the conveying process of the triangular closed-loop belt 23, the cap assembly 18 is subjected to the strong pressure exerted by the compression spring 20. After the triangular closed-loop belt 23 is conveyed, the card group 46 will be completely separated from the gear coupling 17, that is, Figure 15 The needle shaft 48 in the middle descends slowly to ensure that the power storage device 29 can completely release the power under the timing difference and the triangular closed-loop belt 23 can complete the reset and transportation work. As for the slow descent of the needle shaft 48, it has been mentioned before that the speed limiting valve 50 limits the fast growth and slow descent of the needle shaft 48.
