Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying, and particularly relates to an intelligent suspension conveying system and a control method thereof. Background Art

[0002] A suspension conveyor is a device for continuously conveying materials in space. The materials are loaded on special boxes or brackets and run along a predetermined track. The conveyor line can go uphill, downhill and turn in space, with a flexible layout and a small floor area. A suspension conveyor, also known as an overhead conveyor, is a continuous transportation device with a spatially closed line, used for continuous flow conveyance of workpieces and articles inside a workshop or between various workshops. During the continuous flow conveyance process, various sequential process operations can be performed on the workpieces, such as loading the raw materials, surface treatment, painting, drying, cooling, unloading the finished products, etc., and it can work in harsh environments (such as high temperature, harmful media, etc.). Since it makes full use of space and can cooperate with the operations on the ground, it is widely used in large-scale production and modern factories such as furniture factories, bicycle factories, electronics factories, hardware factories, and automobile factories.

The sliding rods are slidably connected with the movable block. The spring is sleeved on the outer surface of the top end of the sliding rod;

[0009] On the left and right sides of the lower surface of the cross beam, through holes corresponding to the left lifting bracket and the right lifting bracket are formed.

The other ends of the first lead screw and the second lead screw respectively penetrate through the left lifting bracket and the right lifting bracket and are rotatably connected with the inner wall of the cavity through bearings. The first lead screw is threadedly connected with the left lifting bracket, and the second lead screw is threadedly connected with the right lifting bracket. On the outer surface of the right side of the first lead screw, a first driven bevel gear is fixedly connected. On the outer surface of the left side of the second lead screw, a second driven bevel gear is fixedly connected. The output end of the first servo motor is located inside the cavity and is fixedly connected with a first driving bevel gear meshed with the first driven bevel gear. The output end of the second servo motor is located inside the cavity and is fixedly connected with a second driving bevel gear meshed with the second driven bevel gear.

[0010] Preferably, the conveying track is of I-shaped steel structure, and the rollers are in contact with the inner bottom wall of the conveying track.

[0015] Preferably, a control method for an intelligent suspension conveying system includes the following steps:

[0016] Step 1: Start the first servo motor to drive the first driving bevel gear to rotate. During the rotation of the first driving bevel gear, it can drive the first lead screw to rotate in cooperation with the first driven bevel gear. Since the first lead screw is threadedly connected to the left lifting frame, the first lead screw can drive the left lifting frame to move during the rotation.

[0017] Step 2: Install the item to be conveyed on the left lifting frame and the right lifting frame through the lifting holes. At this time, the first weight sensor and the second weight sensor transmit data to the controller.

[0018] Step 3: When the weights of the first weight sensor and the second weight sensor are different, the controller starts the first servo motor to drive the first driving bevel gear to rotate.

[0038] As Figure 1-7 shown, an embodiment of the present invention provides an intelligent suspension conveying system, including a conveying track 1, a conveying trolley 3 that can walk and be suspended on the conveying track 1, and a controller 4. The conveying trolley 3 includes a mounting plate 5. On both the left and right sides of the upper surface of the mounting plate 5, U-shaped hanging brackets 6 are fixedly connected. On both the front and rear sides of the U-shaped hanging bracket 6, rollers 7 are rotatably installed. On both the left and right sides of the lower surface of the mounting plate 5, a first weight sensor 8 and a second weight sensor 9 are respectively installed. The lower surfaces of the first weight sensor 8 and the second weight sensor 9 are fixedly connected to a cross beam 10. A cavity 11 is formed inside the cross beam 10, and a left lifting bracket 12 and a right lifting bracket 13 are respectively installed. The bottom ends of the left lifting bracket 12 and the right lifting bracket 13 are both located outside the cross beam 10 and are provided with lifting holes 14. A first servo motor 15 and a second servo motor 16 are installed on the upper surface of the cross beam 10. The first servo motor 15 and the second servo motor 16 are respectively used to drive the left lifting bracket 12 and the right lifting bracket 13 to move.

[0039] As Figure 1 and Figure 6As shown in the figure, in this embodiment, the conveying track 1 is of I-beam steel structure. The roller 7 is in contact with the inner bottom wall of the conveying track 1. Connecting rings 501 are fixedly connected to both the left and right sides of the mounting plate 5. The left and right connecting rings 501 are fixedly connected by connecting hooks 502. In this way, the conveying trolley 3 can be driven to move on the conveying track 1 by an external drive system to convey items.

[0040] As Figure 2 , Figure 5 and Figure 6 As shown in the figure, in this embodiment, long holes 601 are formed on both the front and rear sides of the U-shaped hanging bracket 6. A movable block 602 is slidably connected inside the long holes 601. A rotating shaft 603 is rotatably connected to the movable block 602 through a bearing. The roller 7 is fixedly connected to the outer surface of the rotating shaft 603. A spring 604 is installed between the inner top wall of the movable block 602 and the long hole 601. Two sliding rods 605 are fixedly connected to the inner top wall of the long hole 601. The bottom ends of the sliding rods 605 penetrate through the movable block 602 and are fixedly connected to the inner bottom wall of the long hole 601. The sliding rods 605 are slidably connected to the movable block 602. The spring 604 is sleeved on the outer surface of the top end of the sliding rod 605.

[0041] During use, the U-shaped hanging brackets 6 on both the left and right sides of the conveying trolley 3 are located on the conveying track 1. At this time, due to the action of gravity, the movable block 602 can slide along the sliding rod 605 and compress the spring 604. Through the buffering of the spring 604, the roller 7 rolls more smoothly on the conveying track 1.

[0042] As Figure 5 and Figure 6 As shown in the figure, in this embodiment, bull's-eye bearings 607 are fixedly connected to the top ends of the front and rear sides of the U-shaped hanging bracket 6 by screws 606. The bull's-eye bearings 607 are in contact with the conveying track 1. In this way, the bull's-eye bearings 607 on the front and rear sides of the U-shaped hanging bracket 6 prevent the conveying trolley 3 from moving back and forth.

[0043] As Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the first weight sensor 8, the second weight sensor 9, the first servo motor 15, and the second servo motor 16 are all electrically connected to the controller 4; through holes 1001 corresponding to the left lifting bracket 12 and the right lifting bracket 13 are provided on both the left and right sides of the lower surface of the cross beam 10. In the middle of the inner wall of the cavity 11, a partition 1002 is fixedly connected. The left and right sides of the partition 1002 are respectively rotatably connected to a first lead screw 1003 and a second lead screw 1004 through bearings. The lead pitches of the first lead screw 1003 and the second lead screw 1004 are the same. The other ends of the first lead screw 1003 and the second lead screw 1004 respectively penetrate through the left lifting bracket 12 and the right lifting bracket 13 and are rotatably connected to the inner wall of the cavity 11 through bearings. The first lead screw 1003 is threadedly connected to the left lifting bracket 12, and the second lead screw 1004 is threadedly connected to the right lifting bracket 13. A first driven bevel gear 1005 is fixedly connected to the outer surface on the right side of the first lead screw 1003, and a second driven bevel gear 1006 is fixedly connected to the outer surface on the left side of the second lead screw 1004. The output end of the first servo motor 15 is located inside the cavity 11 and is fixedly connected to a first driving bevel gear 1007 that meshes with the first driven bevel gear 1005. The output end of the second servo motor 16 is located inside the cavity 11 and is fixedly connected to a second driving bevel gear 1008 that meshes with the second driven bevel gear 1006.

[0044] Start the first servo motor 15 through the controller 4 to drive the first driving bevel gear 1007 to rotate. During the rotation of the first driving bevel gear 1007, it can drive the first lead screw 1003 to rotate in cooperation with the first driven bevel gear 1005. At this time, the first lead screw 1003 can drive the left lifting bracket 12 to move during the rotation. At the same time, start the second servo motor 16 to drive the second driving bevel gear 1008 to rotate. During the rotation of the second driving bevel gear 1008, it can drive the second lead screw 1004 to rotate in cooperation with the second driven bevel gear 1006. At this time, the second lead screw 1004 can drive the right lifting bracket 13 to move during the rotation, so as to synchronously adjust the positions of the left lifting bracket 12, the right lifting bracket 13, and the lifted object through the first servo motor 15 and the second servo motor 16.

[0045] As Figure 3 and Figure 4 shown, in this embodiment, guide rods 1009 are fixedly connected to the bottom ends on both the left and right sides of the partition 1002. The left and right two guide rods 1009 respectively penetrate through the left lifting bracket 12 and the right lifting bracket 13 and are fixedly connected to the inner wall of the cavity 11. The left lifting bracket 12 and the right lifting bracket 13 are both slidably connected to the guide rods 1009; through the guide rods 1009, the left lifting bracket 12 and the right lifting bracket 13 can move more stably left and right, avoiding tilting.

[0046] The present invention also proposes a control method for an intelligent suspension conveying system, including the following steps:

[0047] Step 1: Start the first servo motor 15 to drive the first driving bevel gear 1007 to rotate. During the rotation of the first driving bevel gear 1007, it can drive the first lead screw 1003 to rotate in cooperation with the first driven bevel gear 1005. Since the first lead screw 1003 is threadedly connected to the left lifting frame 12, the first lead screw 1003 can drive the left lifting frame 12 to move during rotation, so as to adjust the distance between the left lifting frame 12 and the right lifting frame 13 according to the hole positions of the lifted items, and better lift and convey different items.

[0048] Step 2: Install the item to be conveyed on the left lifting frame 12 and the right lifting frame 13 through the lifting hole 14. At this time, the first weight sensor 8 and the second weight sensor 9 transmit data to the controller 4.

[0049] Step 3: When the weights of the first weight sensor 8 and the second weight sensor 9 are different, the controller 4 starts the first servo motor 15 to drive the first driving bevel gear 1007 to rotate. During the rotation of the first driving bevel gear 1007, it can drive the first lead screw 1003 to rotate in cooperation with the first driven bevel gear 1005. Since the first lead screw 1003 is threadedly connected to the left lifting frame 12, the first lead screw 1003 can drive the left lifting frame 12 to move during rotation. At the same time, start the second servo motor 16 to drive the second driving bevel gear 1008 to rotate. During the rotation of the second driving bevel gear 1008, it can drive the second lead screw 1004 to rotate in cooperation with the second driven bevel gear 1006. Since the second lead screw 1004 is threadedly connected to the right lifting frame 13, the second lead screw 1004 can drive the right lifting frame 13 to move during rotation. Thus, the positions of the left lifting frame 12, the right lifting frame 13 and the lifted item are synchronously adjusted through the first servo motor 15 and the second servo motor 16 until the weights of the first weight sensor 8 and the second weight sensor 9 are the same, so that the pressure of the rollers 7 on both sides on the conveying track 1 is more balanced, avoiding the phenomenon of conveying deviation, and enabling the suspended conveying to operate more stably.

At the same time, start the second servo motor (16) to drive the second driving bevel gear (1008) to rotate. During the rotation of the second driving bevel gear (1008), it cooperates with the second driven bevel gear (1006) to drive the second lead screw (1004) to rotate. At this time, during the rotation of the second lead screw (1004), it can drive the right lifting frame (13) to move. Thus, the positions of the left lifting frame (12), the right lifting frame (13) and the lifted item are synchronously adjusted by the first servo motor (15) and the second servo motor (16) until the weights detected by the first weight sensor (8) and the second weight sensor (9) are the same.
