Description

Technical Field

[0001] This utility model relates to the field of pallet conveying technology, and in particular to an AGV automatic loading and unloading conveying mechanism. Background Technology

[0002] Paper cutters can cut paper because the raw paper produced is usually quite large, and paper comes in different sizes. By cutting, the paper can be classified into different sizes.

[0003] Existing automatic paper cutters can automatically pick up and unload paper, and by using them in conjunction with forklifts or AGVs (Automated Guided Vehicles), they can significantly reduce manpower. When feeding paper into the automatic paper cutter's inlet, a forklift or AGV transports the pallet containing paper to the inlet. After the automatic paper cutter removes the paper from the pallet, the forklift or AGV removes the empty pallet and then transports a new pallet containing paper to the inlet. The process is reversed at the outlet: a forklift or AGV transports an empty pallet to the outlet, and after the empty pallet is filled with cut paper, the forklift or AGV removes the full pallet and transports a new empty pallet to the outlet. However, the following drawbacks still exist when placing pallets containing paper into the automatic paper cutter's inlet and when transferring the uncut paper:

[0004] When using a forklift or AGV intelligent transport vehicle to feed materials into the inlet of an automatic paper cutter, empty pallets need to be removed first, and then pallets containing paper need to be placed in. Therefore, if only one forklift or AGV intelligent transport vehicle is used for feeding and removing pallets, the operation is cumbersome and time-consuming. To improve efficiency, two forklifts or AGV intelligent transport vehicles need to be used: one to feed pallets containing paper into the inlet, and the other to remove empty pallets from the inlet. However, using two forklifts or AGV intelligent transport vehicles will increase investment costs, and the same problem exists at the outlet of the automatic paper cutter.

[0005] Therefore, there is an urgent need for an AGV automatic loading and unloading conveying mechanism to improve feeding and picking efficiency while reducing investment costs. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the technical defects described in the background art.

[0007] Therefore, one objective of this utility model is to propose an AGV automatic loading and unloading conveying mechanism, which aims to solve the problems of low efficiency or high investment cost when picking up and placing pallets at the inlet and outlet of an automatic paper cutter in the prior art.

[0008] To achieve the above objectives, one embodiment of this utility model provides an AGV automatic loading and unloading conveying mechanism, comprising four conveying units: conveying unit 1, conveying unit 2, conveying unit 3, and conveying unit 4, wherein conveying unit 1 and conveying unit 2 are arranged side by side; each conveying unit includes two parallel support frames and an electric roller, the electric roller being installed between the two support frames, and a guide wheel being rotatably connected to one end of each support frame; drive wheels are fixedly installed on the outer surfaces of both ends of the electric roller, and the drive wheels and guide wheels are connected by a conveying chain; support legs are fixedly installed at the bottom of the support frames of conveying unit 1 and conveying unit 2; conveying unit 3 further includes two parallel rails fixed to the ground, connecting frames are fixedly installed at the bottom of the two support frames of conveying unit 3, and mounting seats are fixedly installed at the four corners of the bottom of the connecting frames, with rollers rotatably connected inside the mounting seats, the rollers resting on the top of the rails; a support is fixedly installed at the bottom of the support frame of conveying unit 4.

[0009] The beneficial effects are as follows: AGV intelligent transport vehicles transport empty pallets or pallets filled with paper. At the inlet of the automatic paper cutter, pallets filled with paper enter the inlet in the order of conveyor unit 1 to conveyor unit 3 to conveyor unit 4. After the automatic paper cutter removes the paper, the empty pallets are moved out in the order of conveyor unit 4 to conveyor unit 3 to conveyor unit 2. The AGV intelligent transport vehicle then transports the pallets in the order of first moving the pallets filled with paper to conveyor unit 1, then transferring them to conveyor unit 2 to remove the empty pallets, and then moving in new pallets filled with paper. Thus, only one AGV intelligent transport vehicle is needed at the inlet of the automatic paper cutter. The same principle is used at the outlet of the automatic paper cutter, thereby ensuring high-efficiency handling while reducing equipment investment costs.

[0010] In a preferred embodiment, the top of the support frame is provided with a wear-resistant pad to support the conveyor chain, ensuring that the upper surface of the conveyor chain can fully contact the pallet, thereby ensuring the stability of pallet conveying.

[0011] In a preferred embodiment, guide sheet metal is fixedly connected to the outer sides of both support frames, and the starting and ending sections of the guide sheet metal are chamfered to guide and center the pallet.

[0012] In a preferred embodiment, a limiting ring is provided on the inner side of the roller to prevent the roller from derailing.

[0013] Furthermore, the two adjacent rollers are connected together at their shaft centers by a drive shaft, and a driven sprocket is fixedly installed on the outer surface of the drive shaft. A motor is fixedly installed on the connecting frame, and a drive sprocket is fixedly installed on the output shaft end of the motor. The drive sprocket and the driven sprocket are connected by a drive chain, so that the motor can drive the No. 3 conveying unit to move along the track.

[0014] In a preferred embodiment, a base plate is provided below the support, and a guide rail is fixedly installed on the top of the base plate. A slider is fixedly installed on the bottom of the support, and the slider is slidably connected to the outer surface of the guide rail, so that the fourth conveying unit can move and adjust left and right.

[0015] Furthermore, an installation plate is fixedly installed between the two support frames of the fourth conveyor unit. A second motor is fixedly installed below the installation plate, and a gear is fixedly installed at the output shaft end of the second motor. A rack that meshes with the gear is fixedly installed above the base plate, so that the second motor can drive the fourth conveyor unit to move left and right. When the paper on the tray is not completely centered, causing a deviation between the paper and the feed inlet of the automatic paper cutter, the fourth conveyor unit can be adjusted left and right to make the paper completely correspond to the feed inlet of the automatic paper cutter.

[0016] The beneficial effect is that when the paper on the tray is not completely centered, causing a deviation between the paper and the feed inlet of the automatic paper cutter, the No. 4 conveyor unit can be adjusted left and right to make the paper completely correspond to the feed inlet of the automatic paper cutter, thereby ensuring that the paper enters the automatic paper cutter accurately.

[0017] In a preferred embodiment, both ends of the base plate are fixedly connected to upright plates, and a support plate is fixedly installed on the outer side of the upright plates.

[0018] The beneficial effects are as follows: A hoist can be installed around the No. 4 conveyor unit, and the hoist can be connected to the pallet to raise and lower the No. 4 conveyor unit. For automatic paper cutters that do not have a lifting structure at the material picking and discharging parts, the paper can be allowed to enter the feed port of the automatic paper cutter by raising the No. 4 conveyor unit, or the paper discharged from the discharge port of the automatic paper cutter can fall onto the pallet on the No. 4 conveyor unit by lowering the No. 4 conveyor unit, thus making it suitable for more models of automatic paper cutters.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides an AGV automatic loading and unloading conveying mechanism.

[0032] Example 1:

[0033] like Figure 1 As shown, it includes four conveying units, namely conveying unit 10, conveying unit 20, conveying unit 30 and conveying unit 40, wherein conveying unit 10 and conveying unit 20 are arranged side by side.

[0034] like Figure 2-6 As shown, the conveying unit includes two parallel support frames 50 and an electric roller 501. The electric roller 501 is installed between the two support frames 50 and is located at one end of the two frames 50. Guide wheels 502 are rotatably connected to one end of the two support frames 50. Drive wheels 503 are fixedly installed on the outer surfaces of both ends of the electric roller 501. The drive wheels 503 and guide wheels 502 are connected by a conveying chain 504. Wear-resistant pads 505 are provided on the top of the support frames 50 to support the conveying chain 504 and ensure that the upper surface of the conveying chain 504 can fully contact the pallet 6, thereby ensuring the stability of pallet 6 conveying. Guide sheet metal 506 is fixedly connected to the outer side of both support frames 50. The starting and ending sections of the guide sheet metal 506 are chamfered to guide and center the pallet 6.

[0035] like Figure 2 As shown, support legs 121 are fixedly installed at the bottom of the support frame 50 of both conveying unit 10 and conveying unit 20. The support legs 121 are used to support conveying unit 10 and conveying unit 20, and expansion bolts are used to fix the support legs 121 to the ground to fix conveying unit 10 and conveying unit 20.

[0036] like Figure 3-4As shown, the third conveying unit 30 also includes two parallel linear rails 308 fixed on the ground. Connecting frames 301 are fixedly installed at the bottom of the two support frames 50 of the third conveying unit 30. The connecting frames 301 fix the two support frames 50 together, and mounting seats 302 are fixedly installed at the four corners of the bottom of the connecting frames 301. Rollers 303 are rotatably connected inside the mounting seats 302. The rollers 303 rest on the top of the linear rails 308, and a limiting ring 30 is provided on the inner side of the rollers 303. 31. To prevent rollers 303 from derailing, the shafts of two adjacent rollers 303 are connected together by a drive shaft 304, and a driven sprocket 305 is fixedly installed on the outer surface of the drive shaft 304. A motor 306 is fixedly installed on the connecting frame 301, and a drive sprocket 307 is fixedly installed on the output shaft end of the motor 306. The drive sprocket 307 and the driven sprocket 305 are connected by a drive chain, so that the motor 306 can drive the third conveyor unit 30 to move along the rail 308.

[0037] like Figure 5-6 As shown, a support 401 is fixedly installed at the bottom of the support frame 50 of the fourth conveying unit 40 to support the fourth conveying unit 40.

[0038] The working principle of this utility model is as follows: In use, the fourth conveying unit 40 is installed at the feed port of the automatic paper cutter. The AGV intelligent transport trolley carrying a tray 6 full of paper drives between the two support frames 50 of the first conveying unit 10. Then, by lowering the tray 6, the tray 6 is placed on the first conveying unit 10. At this time, the third conveying unit 30 moves to the position corresponding to the first conveying unit 10. Then, the first conveying unit 10 conveys the tray 6 containing paper to the third conveying unit 30. The third conveying unit 30 then moves to the position corresponding to the fourth conveying unit 40 and conveys the tray 6 containing paper to the fourth conveying unit 40. The automatic paper cutter takes the paper from the fourth conveying unit 40 for cutting.

[0039] During the cutting process described above, the AGV intelligent handling vehicle transports the second tray 6 containing paper to the first conveying unit 10. (See reference...) Figure 7 The AGV intelligent handling vehicle then moves between the two support frames 50 of the second conveying unit 20. After the paper on the fourth conveying unit 40 is removed, the fourth conveying unit 40 transports the empty pallet 6 to the third conveying unit 30, and then to the second conveying unit 20. The AGV intelligent handling vehicle can then transport the empty pallet 6 away and bring over a new pallet 6 filled with paper.

[0040] During the process of the AGV intelligent handling vehicle transporting empty pallets 6 and new pallets 6 filled with paper, the third conveying unit 30 moves to the position corresponding to the first conveying unit 10. The first conveying unit 10 then transports the pallet 6 filled with paper to the third conveying unit 30, and then transfers it to the fourth conveying unit 40. This process is repeated. A similar conveying mechanism is also installed at the discharge port of the automatic paper cutter, using the same principle to pick up and place pallets 6. Therefore, only one AGV intelligent handling vehicle is needed at the inlet or outlet to efficiently transport pallets 6, saving investment costs.

[0041] Example 2:

[0042] like Figure 5-6 As shown, based on Embodiment 1, a base plate 402 is provided below the support 401, and a guide rail 403 is fixedly installed on the top of the base plate 402. A slider 404 is fixedly installed on the bottom of the support 401. The slider 404 is slidably connected to the outer surface of the guide rail 403, so that the fourth conveying unit 40 can move and adjust left and right. An mounting plate 405 is fixedly installed between the two support frames 50 of the fourth conveying unit 40. A second motor 406 is fixedly installed below the mounting plate 405. A gear 407 is fixedly installed on the output shaft end of the second motor 406. A rack 408 that meshes with the gear 407 is fixedly installed on the top of the base plate 402, so that the second motor 406 can drive the fourth conveying unit 40 to move left and right. When the paper on the tray 6 is not completely centered, causing a deviation between the paper and the feed port of the automatic paper cutter, the fourth conveying unit 40 can be adjusted left and right to make the paper completely correspond to the feed port of the automatic paper cutter.

[0043] Example 3:

[0044] like Figure 5-6 As shown in Embodiment 2, both ends of the base plate 402 are fixedly connected to vertical plates 409, and a tray 410 is fixedly installed on the outer side of the vertical plates 409. A lifting mechanism can be installed around the fourth conveying unit 40, connecting the lifting mechanism to the tray 410, allowing for the lifting and lowering of the fourth conveying unit 40. For automatic paper cutters where the material handling and discharging parts do not have lifting structures, the paper can enter the feed inlet of the automatic paper cutter by raising the fourth conveying unit 40, or the paper discharged from the discharge outlet of the automatic paper cutter can fall onto the tray 6 on the fourth conveying unit 40 by lowering the fourth conveying unit 40. It should be noted that the lifting mechanism used can be a hydraulic cylinder, an electric telescopic rod, or a pneumatic cylinder, or an existing structure capable of achieving the lifting purpose, such as a guide rail chain-type lifting mechanism.
