Description

Technical Field

[0001] The present invention belongs to the technical field of material transfer and relates to a station transfer device for carton packaging. Background Art

[0002] Carton packaging refers to a packaging box made of paper materials, which is mainly used to protect products, facilitate storage and transportation, and promote sales. During the processing of packaging cartons, station transfer processing is required, mainly to transfer cartons from one station to another for different production tasks, such as printing, die-cutting, forming, boxing, etc., to ensure the smooth progress of the production process.

[0003] Currently, during the process of transferring and transporting cartons, it is usually necessary to use conveyors or conveyors for transfer. When using conveyors or conveyors for transfer, only linear transmission and transfer can be achieved. If the direction of transfer needs to be changed, it is difficult to achieve with conveyors or conveyors, and only manual transfer can be used. The entire transfer device has a narrow scope of application and is inconvenient to use. Summary of the Invention

[0004] In view of this, the present invention provides a station transfer device for carton packaging.

[0005] A station transfer device for carton packaging includes a base, a connecting seat, a turntable, a stepping motor, and a fixing mechanism. A connecting seat is connected to the top of the base, a turntable is rotatably connected to the connecting seat, a stepping motor is installed in the middle of the upper part of the base, and the output shaft of the stepping motor is connected to the center of the turntable so that the stepping motor can drive the turntable to rotate when operating. A fixing mechanism for fixing the carton is provided on the turntable.

[0006] Further, the fixing mechanism includes a rotating block, a servo motor, a rotating rod, and a clamping structure. A plurality of rotating blocks are rotatably connected to the turntable at equal intervals along the circumference. A servo motor is installed on the rotating block, and the output shaft of the servo motor is connected to the turntable. When the servo motor operates, since the output shaft is fixed, the servo motor body will rotate, driving the rotating block to rotate and adjusting the angle of the rotating block. A rotating rod is rotatably connected to the rotating block, and a clamping structure for clamping the carton is provided on the rotating rod.

[0007] Further, the clamping structure includes a U-shaped plate, a fixing cylinder, and a clamping plate. A U-shaped plate is installed at the end of the rotating rod. Clamping plates are slidably connected to both the front and rear sides of the U-shaped plate. Fixing cylinders are installed at the lower parts of both the front and rear sides of the U-shaped plate, and the telescopic rods of the fixing cylinders are connected to the clamping plates so that the telescopic rods of the fixing cylinders can drive the clamping plates to slide. When the two clamping plates approach each other, the carton can be clamped.

[0008] Further description: It further includes a commutation mechanism. The commutation mechanism includes an electric push rod, a connecting rod, a bevel rack and a bevel gear. Electric push rods are installed at the lower part of the front side and the upper part of the rear side of the turntable. A connecting rod is installed on the body of the electric push rod. A bevel rack is connected to the connecting rod. A bevel gear is connected to the rotating rod. The bevel rack is located at the moving track of the bevel gear, so that the bevel gear will mesh with the bevel rack and be rubbed and rotated by the bevel rack when moving.

[0009] Further description: It further includes a guiding mechanism. The guiding mechanism includes a mounting rod, a guiding plate, an adjusting screw rod and a sliding frame. Two front and rear mounting rods are connected to the right side of the connecting seat. Sliding frames are slidably connected to the right sides of the two mounting rods. The sliding frames can slide back and forth along the mounting rods. Guiding plates are connected to the sides of the two sliding frames close to each other. When the paper box is conveyed by the conveyor belt to the U-shaped plate, the paper box can be guided by the two guiding plates. An adjusting screw rod is rotatably connected to the right side of the mounting rod. The adjusting screw rod is in threaded cooperation with the sliding frame, so that the adjusting screw rod can drive the sliding frames on both sides to slide and adjust when rotating. Knobs are arranged at the ends of the two adjusting screw rods away from each other for facilitating the operation of rotating the adjusting screw rod.

[0010] Further description: It further includes a locking mechanism. The locking mechanism includes a locking ring, locking protrusions, locking rods and elastic members. A locking ring is connected to the rotating rod. A plurality of locking protrusions are evenly spaced and connected to the locking ring. Two locking rods are slidably arranged on the rotating block. The two locking rods are arranged oppositely. The locking rods can be stuck at two locking protrusions, so as to limit the rotating rod through the cooperation of the locking rods, locking protrusions and locking ring. An elastic member is connected between the locking rod and the rotating block. The elastic member is a connecting spring.

[0011] Further description: It further includes a height adjusting mechanism. The height adjusting mechanism includes a base and a lifting cylinder. Bases are arranged on the front, rear, left and right sides below the base. A lifting cylinder is installed in each base. The telescopic rod of the lifting cylinder is connected to the bottom of the base. Controlling the telescopic movement of the telescopic rod of the lifting cylinder can drive the base to lift and lower to adjust the height of the whole device.

[0012] Further description: It further includes a supporting bracket. Supporting brackets are connected to the bottoms of the two guiding plates. When the paper box moves between the two guiding plates, if the U-shaped plate has not rotated to align with the guiding plates, the bottom of the paper box will be supported by the supporting bracket, so as to play a role in supporting the paper box and prevent the paper box from falling.

[0013] The beneficial effects of the present invention are as follows: 1. When the present invention transports the paper box, not only can the rotation of the turntable drive the U-shaped plate for linear transportation, but also when it is necessary to change the transportation direction, the servo motor can be controlled to rotate to drive the swing rod to swing, adjust the orientation of the U-shaped plate, and adjust the transportation direction, so that the applicable range of the entire transportation device is wider and it is more convenient to use.

[0014] 2. When the present invention transports the paper box, it can also make the swing rod rotate by itself through the cooperation of the tapered rack and the bevel gear, so as to drive the paper box to flip, thereby adjusting the orientation of the paper box after rotation, and performing a face-changing operation according to the different treatments required for different faces of the paper box, which is convenient for subsequent operations.

Detailed implementation manners

[0027] The present invention will be further described below in conjunction with specific embodiments. The schematic embodiments and descriptions herein are used to explain the present invention, but not to limit the present invention.

[0028] A station transfer device for carton packaging, as Figures 1-4 shown, includes a base 1, a connecting seat 2, a turntable 3, a stepper motor 4 and a fixing mechanism. The top of the base 1 is connected to the connecting seat 2. The turntable 3 is rotatably connected to the connecting seat 2. The stepper motor 4 is installed in the middle of the upper part of the base 1. The output shaft of the stepper motor 4 is connected to the center of the turntable 3, so that the stepper motor 4 can drive the turntable 3 to rotate when operating. A fixing mechanism for fixing the carton is provided on the turntable 3.

[0029] As Figures 2-4 shown, the fixing mechanism includes a rotating block 51, a servo motor 52, a rotating rod 53 and a clamping structure. A plurality of rotating blocks 51 are rotatably connected to the turntable 3 at equal intervals along the circumference. The servo motor 52 is installed on the rotating block 51. The output shaft of the servo motor 52 is connected to the turntable 3. When the servo motor 52 operates, since the output shaft is fixed, the servo motor 52 body will rotate, thereby driving the rotating block 51 to rotate and adjusting the angle of the rotating block 51. The rotating rod 53 is rotatably connected to the rotating block 51, and a clamping structure for clamping the carton is provided on the rotating rod 53.

[0030] As Figures 2-4 shown, the clamping structure includes a U-shaped plate 54, a fixed cylinder 55 and a clamping plate 56. The U-shaped plate 54 is installed at the end of the rotating rod 53. Clamping plates 56 are slidably connected to both the front and rear sides of the U-shaped plate 54. Fixed cylinders 55 are installed at the lower parts of both the front and rear sides of the U-shaped plate 54. The telescopic rods of the fixed cylinders 55 are connected to the clamping plates 56, so that the telescopic rods of the fixed cylinders 55 can drive the clamping plates 56 to slide. When the two clamping plates 56 approach each other, the carton can be clamped.

[0031] When it is necessary to transfer workstations during the production process of carton packaging, this equipment can be used. When in use, place this equipment between two or several production lines in different directions, and align the U-shaped plate 54 on the right side with the production line for conveying cartons. Subsequently, the production line will convey the cartons to the U-shaped plate 54 on the right side. At this time, control the telescopic rods of the two fixed cylinders 55 at the U-shaped plate 54 to contract, driving the two clamping plates 56 to approach each other, thereby clamping the cartons. After clamping, the stepping motor 4 can be controlled to drive the turntable 3 to rotate, thereby transferring the cartons through the U-shaped plate 54. When the next U-shaped plate 54 rotates to align with the production line for conveying cartons, new cartons can be fixed according to the above operations. When it is necessary to transfer the cartons to other production lines, when the U-shaped plate 54 rotates to align with other production lines and the cartons are also above the production line, then control the telescopic rods of the two fixed cylinders 55 to extend, driving the two clamping plates 56 to move away from each other, thereby loosening the cartons and placing the cartons on the production line. If the production lines are located on the front and back sides of this equipment, the servo motor 52 can be controlled to operate. When the servo motor 52 operates, since its output shaft is fixed on the turntable 3, the output shaft of the servo motor 52 will not rotate, but the body of the servo motor 52 rotates. The rotation of the body of the servo motor 52 will drive the rotating block 51 to rotate, thereby driving the rotating rod 53 and the U-shaped plate 54 to flip. When the U-shaped plate 54 flips, it can flip forward or backward according to the rotation direction of the servo motor 52 to place the cartons carried on the U-shaped plate 54 on the front or back production lines respectively, and then carry out the conveying work of the cartons. In this way, this device can be used to transfer cartons during the carton packaging process, and can transfer to production lines in different directions during the transfer process, with a wider scope of application.

[0032] As Figure 5 shown, it further includes a commutation mechanism. The commutation mechanism includes an electric push rod 61, a connecting rod 62, a bevel gear rack 63, and a bevel gear 64. Electric push rods 61 are installed at the lower part of the front side and the upper part of the rear side of the turntable 3. A connecting rod 62 is installed on the body of the electric push rod 61. A bevel gear rack 63 is connected to the connecting rod 62. A bevel gear 64 is connected to the rotating rod 53. The bevel gear rack 63 is located at the moving track of the bevel gear 64, so that the bevel gear 64 will mesh with the bevel gear rack 63 and be rubbed and rotated by the bevel gear rack 63 when moving.

[0033] Initially, the telescopic rod of the electric push rod 61 is in the extended state. During the transfer process, if it is necessary to change the orientation of the paper box, the telescopic rods of the two electric push rods 61 can be controlled to retract, driving the connecting rod 62 and the bevel gear rack 63 to move forward. After the bevel gear rack 63 moves, it is located at the movement track of the bevel gear 64. Subsequently, when the rotating rod 53 moves, it will drive the bevel gear 64 to move. After the bevel gear 64 moves, it will move to mesh with the bevel gear rack 63 and be rubbed by the bevel gear rack 63 to rotate, thereby driving the rotating rod 53 to rotate. When the bevel gear 64 moves to disengage from the bevel gear rack 63, the rotating rod 53 just rotates 180 degrees, thus performing a face-changing treatment on the paper box. In this way, the orientation of the paper box during the transfer process can be changed. When the bevel gear 64 rotates to mesh with the bevel gear rack 63 below, it can drive the rotating rod 53 to rotate and reset.

[0034] As Figure 6 and Figure 7 shown, it further includes a guiding mechanism. The guiding mechanism includes a mounting rod 71, a guiding plate 72, an adjusting screw 73, and a sliding bracket 74. Two front and rear mounting rods 71 are connected to the right side of the connecting seat 2. The right sides of the two mounting rods 71 are both slidably connected with a sliding bracket 74. The sliding bracket 74 can slide back and forth along the mounting rod 71. A guiding plate 72 is connected to the side of each of the two sliding brackets 74 that are close to each other. When the paper box is conveyed by the conveyor belt to the U-shaped plate 54, the two guiding plates 72 can be used to guide the paper box. The right side of the mounting rod 71 is rotatably connected with an adjusting screw 73. The adjusting screw 73 is in threaded cooperation with the sliding bracket 74, so that when the adjusting screw 73 rotates, it can drive the two sliding brackets 74 on both sides to slide through the thread for adjustment. Knobs are provided at the ends of the two adjusting screws 73 that are away from each other, so as to facilitate operating the adjusting screw 73 to rotate.

[0035] When the paper box enters the U-shaped plate 54 through the assembly line, it will first contact the two guiding plates 72 and be guided by the two guiding plates 72 into the U-shaped plate 54, thus playing a role in guiding the paper box. In the actual operation process, the distance between the two guiding plates 72 can be adjusted according to the size of the paper box. During adjustment, only by rotating the adjusting screw 73 can the two guiding plates 72 be driven to approach or move away from each other through the thread, so as to achieve the effect of adjusting the distance between the guiding plates 72.

[0036] As Figure 8As shown in the figure, it further includes a locking mechanism. The locking mechanism includes a locking ring 81, a locking protrusion 84, a locking rod 82, and an elastic member 83. A locking ring 81 is connected to the rotating rod 53. A plurality of locking protrusions 84 are evenly spaced and connected to the locking ring 81. Two locking rods 82 are slidably arranged on the rotating block 51. The two locking rods 82 are arranged oppositely. The locking rod 82 can be stuck at two locking protrusions 84, so as to limit the rotating rod 53 through the cooperation of the locking rod 82, the locking protrusion 84, and the locking ring 81. An elastic member 83 is connected between the locking rod 82 and the rotating block 51. The elastic member 83 is a connecting spring.

[0037] When the rotating rod 53 rotates, it will drive the locking ring 81 and the locking protrusion 84 to rotate. When the locking protrusion 84 rotates, it will repeatedly squeeze the locking rod 82 to move upward, and the elastic member 83 is stretched. After the rotating rod 53 finishes rotating, under the action of the elastic member 83, the locking rod 82 resets and gets stuck at the locking protrusion 84, so as to limit the locking ring 81 and the rotating rod 53 and prevent the rotating rod 53 from rotating randomly.

[0038] As Figure 9 and Figure 10 As shown in the figure, it further includes a height adjustment mechanism. The height adjustment mechanism includes a base 91 and a lifting cylinder 92. The base 91 is arranged on the front, rear, left, and right sides of the bottom of the base 1. A lifting cylinder 92 is installed in each base 91. The telescopic rod of the lifting cylinder 92 is connected to the bottom of the base 1. Controlling the telescopic movement of the telescopic rod of the lifting cylinder 92 can drive the base 1 to lift and lower to adjust the height of the entire device.

[0039] When it is necessary to adjust the height of the entire device, the lifting cylinder 92 can be controlled to lift and lower to drive the base 1 to move up and down, so as to adjust the height of the entire device to adapt to the use of assembly lines at different heights.

[0040] As Figure 11 As shown in the figure, it further includes a supporting bracket 10. The bottom of both guide plates 72 is connected to the supporting bracket 10. When the paper box moves between the two guide plates 72, if the U-shaped plate 54 has not rotated to align with the guide plates 72, the bottom of the paper box will be supported by the supporting bracket 10, so as to play a role in supporting the paper box and prevent the paper box from falling.

[0041] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
