Description

Technical Field

[0001] The present invention belongs to the technical field of automatic guided vehicles, and in particular relates to an AGV cargo handling device for a packaging production line. Background Art

[0002] An AGV is a transport vehicle equipped with an electromagnetic or optical automatic navigation system, capable of traveling along a prescribed path and equipped with safety features and various loading and unloading functions. These vehicles, which do not require a driver in industrial applications, are powered by rechargeable batteries. Their path and behavior are typically controlled by a computer or by electromagnetic tracks attached to the floor. The electromagnetic tracks provide information for the automated guided vehicle's movement and actions.

[0003] However, in actual production, AGV carts can only move goods to the side of the production line, but cannot transport goods to the production line. The transportation work still relies on manual work, and the cargo boxes used on the production line also need to be placed manually on the AGV cart, which directly affects production efficiency.

[0004] Based on this, the present invention designs an AGV cargo handling device for a packaging production line to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an AGV cargo handling device for a packaging production line with a simple structure and reasonable design in order to solve the above problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] An AGV cargo handling device for a packaging production line includes an AGV trolley, the top of the AGV trolley is connected to a rectangular frame, the bottom four corners of the rectangular frame are provided with moving wheels, the top four corners of the rectangular frame are fixed with telescopic adjustment rods, the top of the telescopic adjustment rod is fixed with a placement table, a vertical rotating shaft is rotatably installed on the placement table, a No. 1 motor is fixed to the bottom of the placement table, the output shaft of the No. 1 motor is fixedly connected to the rotating shaft, the No. 1 motor is used to drive the rotating shaft to rotate, a rectangular plate is fixed to the top of the rotating shaft, and the top of the rectangular plate is provided with a The guide rail has two clamping plates movably connected to the top of the rectangular plate, a transmission screw is provided between the two clamping plates, the transmission screw includes two screw shafts with opposite rotation directions, the transmission screw is threadedly connected to the two clamping plates, a mounting plate is fixed on the top of the guide rail, a No. 2 motor is fixed on the top of the mounting plate, a synchronous belt is provided between the No. 2 motor and the transmission screw, a secondary clamping mechanism is provided on the clamping plate, a bottom support mechanism is provided in the clamping plate, the AGV trolley is electrically connected to the No. 1 motor and the No. 2 motor, and the AGV trolley is used to control the operation of the No. 1 motor and the No. 2 motor.

[0008] The goods needed for the production line are placed on the placement table. The AGV (Automated Guided Vehicle) drives the device to the designated position on the production line. Upon reaching the designated position, the AGV stops, leaving one end of the clamping plate on the placement table and the other on the production line. Once the position is correct, the AGV activates motor number two, which drives the synchronous belt, which in turn rotates the drive screw, which in turn rotates two screw shafts with opposite rotations. The rotation of the two screw shafts moves the two clamping plates toward each other along the guide rails. The two clamping plates, located at one end of the production line, clamp empty boxes or unwanted objects on the line. The two clamping plates, located at one end of the placement table, clamp newly arrived boxes on the placement table. Once the clamping plates are in operation, motor number one, controlled by the AGV, activates the rotating shaft, which in turn rotates the rectangular plate and the clamping plates, swapping the positions of the objects held by the clamping plates. The newly arrived objects on the placement table are moved onto the production line, while the empty boxes on the line are moved onto the placement table. After the positions are swapped, the second motor reverses, and the drive screw moves the two clamping plates away from each other, allowing the empty container to be lowered. After the cargo is moved, the AGV moves the device to the next location. The secondary clamping mechanism provides a secondary grip to prevent the container from falling during movement. The bottom support mechanism provides support for heavier containers, preventing them from falling.

[0009] Preferably, two rectangular grooves are provided on the sides where the two splints are close to each other, and the No. 2 clamping mechanism includes an inflatable telescopic rod installed at the rectangular groove, and a movable plate is fixed to the free end of the inflatable telescopic rod, and two No. 1 plates are fixed on the sides where the two splints are close to each other, and a No. 1 telescopic rod is fixed on the side of the No. 1 plate close to the end of the splint, and the telescopic direction of the No. 1 telescopic rod is consistent with the length direction of the splint, and two No. 1 grooves are provided on the ends of the two splints close to each other, and a No. 2 telescopic rod is fixed at the No. 1 groove, and the telescopic direction of the No. 2 telescopic rod is consistent with the axial direction of the transmission screw, and a baffle is fixed on the end of the No. 2 telescopic rod facing the outside of the No. 1 groove, and the inner cavities of the inflatable telescopic rod, the No. 1 telescopic rod and the No. 2 telescopic rod on the same splint are connected.

[0010] Preferably, the base support mechanism includes two or more racks installed on the side walls of the splint, the racks are located at the ends of the splint, and two connecting rods are rotatably connected to the splint at the rectangular grooves. Gears are fixed to the top ends of the connecting rods, and the gears are engaged with adjacent racks. A support plate is fixed to the bottom end of the connecting rod.

[0011] Preferably, the support plate is made of titanium alloy material, and the side wall of the support plate is provided with a beveled edge.

[0012] Preferably, the inner cavity volume of the inflatable telescopic rod is more than ten times that of the No. 1 telescopic rod, and the No. 1 telescopic rod has at least two sections.

[0013] Preferably, two semicircular load-bearing plates are fixed to the side walls of the rectangular plate, the top surface of the load-bearing plates is flush with the top surface of the placement table, and the tops of the placement table and the load-bearing plates are each provided with more than two mounting grooves, and steel balls are placed in the mounting grooves.

[0014] The beneficial effects of the present invention are:

[0015] 1) The present invention clamps the cargo boxes by the relative movement of two clamping plates, which not only allows the required cargo boxes to be placed on the production line, but also allows the empty cargo boxes to be moved to the placement table and taken away after use, thus realizing the automatic handling of goods, thereby reducing the labor burden and improving production efficiency;

[0016] 2) The present invention can greatly reduce the probability of the goods falling during the transfer process by performing secondary clamping and lifting on the goods, which not only ensures the safety of the goods, but also ensures the normal progress of production.

DETAILED DESCRIPTION

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-5As shown, an AGV cargo handling device for a packaging production line includes an AGV trolley 1, a rectangular frame 2 is connected to the top of the AGV trolley 1, and moving wheels 3 are provided at the four corners of the bottom of the rectangular frame 2. Telescopic adjustment rods 4 are fixed to the four corners of the top of the rectangular frame 2, and a placement table 5 is fixed to the top of the telescopic adjustment rod 4. A vertical rotating shaft 6 is rotatably installed on the placement table 5, and a No. 1 motor 7 is fixed to the bottom of the placement table 5. The output shaft of the No. 1 motor 7 is fixedly connected to the rotating shaft 6, and the No. 1 motor 7 is used to drive the rotating shaft 6 to rotate. A rectangular plate 8 is fixed to the top of the rotating shaft 6, and a guide rail is provided on the top of the rectangular plate 8. The top of the rectangular plate 8 is movably connected to two splints 9, and a transmission screw is provided between the two splints 9. The transmission screw includes two screw shafts 10 with opposite rotation directions. The transmission screw is threadedly connected to the two splints 9. A mounting plate 11 is fixed to the top of the guide rail, and a No. 2 motor 12 is fixed to the top of the mounting plate 11. A synchronous belt 13 is provided between the No. 2 motor 12 and the transmission screw. A secondary clamping mechanism is provided on the splint 9, and a bottom support mechanism is provided in the splint 9. The AGV trolley 1 is electrically connected to the No. 1 motor 7 and the No. 2 motor 12. The AGV trolley 1 is used to control the operation of the No. 1 motor 7 and the No. 2 motor 12.

[0026] In the above embodiment, the goods required for the production line are placed on the placement table 5, and the AGV 1 is used as a power source to drive the device to a designated position on the production line. Upon reaching the designated position, the AGV 1 stops, with one end of the clamping plate 9 positioned on the placement table 5 and the other end positioned on the production line. After the position is corrected, the AGV 1 controls the second motor 12 to start. This drives the timing belt 13, which in turn rotates the drive screw, thereby rotating the two screw shafts 10, which rotate in opposite directions. The rotation of the two screw shafts 10 causes the two clamping plates 9 to move toward each other along the guide rails. The two clamping plates 9, located at one end of the production line, clamp empty containers or unwanted objects on the line. The two clamping plates 9, located at one end of the placement table 5, clamp newly arrived containers on the placement table 5. Once the clamping plates 9 are in operation, the first motor 7, under the control of the AGV 1, starts, driving the rotating shaft 6, which in turn rotates the rectangular plate 8 and the clamping plates 9, thereby interchangeably holding objects at both ends of the clamping plates 9. The objects just transported to the placement table 5 are moved to the production line, and the empty cargo boxes on the production line are moved to the placement table 5. After the position is interchanged, the No. 2 motor 12 is reversed, and the two clamps 9 are moved away from each other under the action of the transmission screw, thereby putting down the empty cargo box. After completing the transportation of the goods, the AGV trolley 1 drives the device to the next location. The secondary clamping mechanism can perform secondary clamping on the cargo box to prevent the cargo box from falling during the movement. The bottom support mechanism can lift the bottom of the heavier cargo box to prevent the cargo box from falling. The present invention clamps the cargo box through the relative movement of the two clamps 9, which can not only place the required cargo box on the production line, but also move the empty cargo box that is no longer needed after use to the placement table 5 and take it away, realizing the automatic transportation of goods, thereby reducing the labor burden and improving production efficiency.

[0027] As a further solution of the present invention, two rectangular grooves 14 are provided on the side where the two splints 9 are close to each other, and the No. 2 clamping mechanism includes an inflatable telescopic rod 15 installed at the rectangular groove 14, and the free end of the inflatable telescopic rod 15 is fixed with a movable plate 16, and two No. 1 plates 17 are fixed on the side where the two splints 9 are close to each other, and a No. 1 telescopic rod 18 is fixed on the side of the No. 1 plate 17 close to the end of the splint 9, and the telescopic direction of the No. 1 telescopic rod 18 is consistent with the length direction of the splint 9, and two No. 1 grooves 19 are provided on the ends of the two splints 9 close to each other, and a No. 2 telescopic rod 20 is fixed at the No. 1 groove 19, and the telescopic direction of the No. 2 telescopic rod 20 is consistent with the axial direction of the transmission screw, and a baffle 21 is fixed on the end of the No. 2 telescopic rod 20 facing the outside of the No. 1 groove 19, and the inner cavities of the inflatable telescopic rod 15, the No. 1 telescopic rod 18 and the No. 2 telescopic rod 20 located on the same splint 9 are connected.

[0028] In the above embodiment, when the clamped goods are irregular or deflected during the clamping process, the goods are likely to fall during the transfer process. By providing a movable plate 16, the movable plate 16 is pressed into the rectangular groove 14 during the process of the two clamping plates 9 clamping the goods, so that the gas in the inflatable telescopic rod 15 is pressed toward the first telescopic rod 18 and the second telescopic rod 20. The first telescopic rod 18 is extended by the action of the gas entering the inflatable telescopic rod 15, so that the free end of the first telescopic rod 18 rests on the goods. At the same time, the second telescopic rod 20 is extended by the action of the gas entering the inflatable telescopic rod 15, so that the baffle 21 is pushed out from the first groove 19, so that the first telescopic rod 18 and the baffle 21 clamp the goods, completing the secondary clamping of the goods. Irregular objects can be fixed for a second time, and the deviation of the goods can also be adjusted for a second time, thereby ensuring good clamping of the goods.

[0029] As a further solution of the present invention, the base support mechanism includes more than two racks 22 installed on the side walls of the splint 9, the racks 22 are located at the ends of the splint 9, and two connecting rods 23 are rotatably connected to the splint 9 at the rectangular groove 14. The top ends of the connecting rods 23 are fixed with gears 24, and the gears 24 are engaged with adjacent racks 22. The bottom ends of the connecting rods 23 are fixed with support plates 25.

[0030] In the above embodiment, heavy cargo may slide off the plywood 9 and fall to the ground, causing economic losses. By providing a rack 22, when the movable plate 16 is squeezed, the rack 22 moves away from the cargo. During this movement, the rack 22 drives the gear 24 to rotate, thereby causing the connecting rod 23 to rotate. The connecting rod 23 drives the support plate 25 at its bottom to rotate at a set angle, so that the support plate 25 and the plywood 9 are perpendicular to each other. At this time, the support plate 25 is directly below the cargo. When the heavy cargo slides downward and contacts the support plate 25, the support plate 25 can effectively support the cargo, thereby effectively preventing the cargo from falling.

[0031] As a further solution of the present invention, the support plate 25 is made of titanium alloy material, and the side wall of the support plate 25 is provided with a bevel.

[0032] In the above embodiment, the titanium alloy material has a strong strength and is not easily deformed under the downward pressure of the cargo, thereby ensuring the long-term use of the device. The side walls of the support plate 25 are provided with beveled edges to help the support plate 25 easily enter the bottom of the cargo during movement, avoiding the situation where the support plate 25 is stuck on the edge of the cargo.

[0033] As a further solution of the present invention, the inner cavity volume of the inflatable telescopic rod 15 is more than ten times that of the first telescopic rod 18, and the number of sections of the first telescopic rod 18 is at least two.

[0034] In the above embodiment, the large internal volume of the inflatable telescopic rod 15 allows a greater amount of gas to enter the first telescopic rod 18 and the second telescopic rod 20, thereby enabling the first telescopic rod 18 to achieve a greater extension and contraction. Furthermore, the multi-section design of the first telescopic rod 18 provides a wider range of extension and contraction, enabling it to grip even narrow cargo, further expanding the applicability of the device.

[0035] As a further solution of the present invention, two semicircular load-bearing plates 26 are fixed to the side walls of the rectangular plate 8, and the top surface of the load-bearing plate 26 is flush with the top surface of the placement table 5. The top of the placement table 5 and the load-bearing plate 26 are provided with more than two installation grooves, and steel balls are placed in the installation grooves.

[0036] In the above embodiment, the provision of the load-bearing plate 26 allows the cargo to be stably placed on the placement platform 5 during the rotation of the rectangular plate 8, preventing height differences or drops. Furthermore, the steel balls disposed on the tops of the placement platform 5 and the load-bearing plate 26 reduce friction during the movement of the cargo, facilitating smooth movement and preventing damage or drops. They also reduce the operating pressure on the second motor 12, preventing significant repetition issues.

[0037] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
