[0037] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, which is widely used in food, medicine, chemical industry and other fields. In the production process, the plastic film is placed horizontally after being rolled and packaged. The film roll needs to be flipped to an upright state to facilitate the subsequent stacking work. However, the traditional film roll flipping usually adopts hoisting flipping or manual flipping. Hoisting flipping is cumbersome, requires manual assistance, and has low flipping efficiency. Manual flipping is labor-intensive, time-consuming and labor-intensive, which affects production efficiency.

[0038] Based on this, see Figure 1-Figure 4 The flipping device 1000 provided in the embodiment of the present invention can effectively solve the above-mentioned technical problems. The flipping device 1000 can automatically flip the plastic film roll from a horizontal state to a vertical state, which can improve production efficiency and reduce the labor intensity of workers. The flipping device 1000 can be applied to the production line of plastic film rolls and other items. The production line with the flipping device 1000 also has the same functions as above, which will not be described in detail here.

[0039] The flipping device 1000 in this embodiment is mainly used in a plastic film roll production line. The plastic film roll production line in this embodiment includes a drying device, a winding device and a flipping device 1000. After the plastic film is produced, it is dried in the drying device and then transferred to the winding device to wind the plastic film into multiple plastic film rolls. The plastic film rolls are then transferred to the flipping device 1000, and the flipping device 1000 is used to flip the plastic film rolls from a horizontal state to a vertical state, so that the stacking robot can remove the film rolls for stacking. Of course, the plastic film production line can also include various equipment such as cleaning equipment to meet various production needs of the plastic film production line, which is not limited here. In addition to being used for flipping plastic film rolls, the flipping device 1000 can also be used to flip other items, which is not limited here.

[0040] Figure 1 Schematic diagram of a flip device 1000 provided in an embodiment of the present invention, as shown in FIG. Figure 1As shown, the flipping device 1000 in this embodiment includes a base 100, a rotating device 200, a flipping device 300 and a placing device 400. The rotating device 200 is arranged on the base 100 and can rotate around the vertical direction relative to the base 100. The flipping device 300 includes a flip seat 310 and a telescopic rod 320. The flip seat 310 is connected to the rotating device 200. One end of the telescopic rod 320 is hinged to the flip seat 310, and the other end of the telescopic rod 320 is hinged to the placing device 400. The placing device 400 is hinged to the flip seat 310. The placing device 400 is used to place the object 2000 to be flipped. The telescopic rod 320 is used to drive the placing device 400 to rotate from the horizontal direction to the vertical direction, or from the vertical direction to the horizontal direction. The horizontal direction is perpendicular to the vertical direction. By setting the rotating device 200, the flipping device 300, the placing device 400 and the object 2000 to be flipped located on the placing device 400 can be rotated in a horizontal plane. By setting the flipping device 300, the placement device 400 can be rotated 90 degrees, and the object to be flipped 2000 can be flipped from a horizontal state to an upright state, so that the external palletizing robot can remove the object to be flipped 2000 for palletizing. The rotating device 200 and the flipping device 300 can together rotate the object to be flipped 2000 to a position that is convenient for handling. Figure 1 The direction pointed by the dashed axis.

[0041] Figure 2 It is a schematic diagram of a first state of the flip device 1000 provided in an embodiment of the present invention, that is, a schematic diagram of an initial state; Figure 3 It is a schematic diagram of the second state of the flip device 1000 provided in an embodiment of the present invention, that is, a schematic diagram after being rotated 90° in a horizontal plane; Figure 4 FIG. 1 is a schematic diagram of the third state of the flip device 1000 provided in an embodiment of the present invention, that is, a schematic diagram of the flip device 1000 flipped 90° from the horizontal state to the vertical state. Figure 2 , Figure 3 and Figure 4, when the part 2000 to be flipped is transported to the flipping device 1000 and fixed to the placement device 400, the rotating device 200 rotates in the horizontal plane, thereby driving the placement device 400 and the flipping device 300 to rotate a certain angle in the horizontal plane, and then the telescopic rod 320 of the flipping device 300 retracts and drives the placement device 400 to rotate 90°, from a horizontal state to an upright state. When the part 2000 to be flipped on the placement device 400 is removed by other equipment such as a palletizing robot, the flipping device 300 turns back from the upright state to the horizontal state, and all devices return to the initial state so as to flip the next part 2000 to be flipped. The rotation angle of the rotating device 200 is determined according to the actual working conditions, as long as the rotating device 200 can rotate the placement device 400 and the flipping device 300 to a position that is convenient for the next step. The rotating device 200 in this embodiment can rotate 360° in the horizontal plane.

[0042] See also Figure 3 and Figure 4 , and combined with Figure 1 , the telescopic rod 320 of the flipping device 300 in this embodiment is a rod cylinder. The telescopic rod 320 can rotate relative to the flip seat 310. During the rotation of the telescopic rod 320, the telescopic rod 320 can be extended or retracted to adjust the position of the placement device 400. In the process of flipping the flipping member 2000 from the horizontal state to the vertical state, at the beginning of the flipping, that is, when the flipping member 2000 is in the horizontal state, the cylinder tension is the largest, and as the flipping angle increases, the cylinder tension gradually decreases; when the center of gravity of the flipping member 2000 and the flipping axis are coplanar in the vertical direction, the cylinder tension decreases to zero; after exceeding the coplanar position, the pressure of the cylinder gradually increases, and when the flipping member 2000 is rotated to the vertical direction, the pressure of the cylinder is the largest. During the flipping process, the pulling pressure required by the cylinder is different due to different flipping angles. Therefore, during the flipping process, an impact may occur, causing the flipping member 2000 to rotate unsteadily, or even causing the flipping member 2000 to fall. In order to overcome the above problems, a position sensor 600 is provided on the telescopic rod 320 in this embodiment. The position sensor 600 can monitor the change of the cylinder position, and feed back the acquired information to the external controller, compare it with the set value, and control the flow direction and pressure of the air source according to the real-time position of the cylinder to make the flipped piece 2000 flip smoothly and prevent it from falling.

[0043] Specifically, when the cylinder is started, a pulling force is generated on the push rod of the cylinder, and as the cylinder rotates, the pulling force gradually decreases; when the position sensor 600 detects that the cylinder has just exceeded the position where the center of gravity of the part to be flipped 2000 and the flip axis are coplanar in the vertical direction, the external controller controls the solenoid valve to change the air source direction of the cylinder, so that the cylinder push rod gradually generates pressure, and as it rotates to the vertical direction, the cylinder pressure is controlled to gradually increase, so that the part to be flipped 2000 can be flipped smoothly. After the stacking robot grasps the part to be flipped 2000, the rodless cylinder 442 supplies air in the reverse direction, driving the push plate 420 to release the part to be flipped 2000, and the stacking robot removes the part to be flipped 2000, the rod cylinder drives the roller frame 410 to lie flat, and the servo motor drives the rotating frame 210 to reverse to the initial position, completing a flipping operation.

[0044] In order to limit the position of the to-be-turned part 2000 when it is turned to the upright state and to buffer its turning force, a second buffer 110 is also provided on the base 100 in this embodiment. The second buffer 110 is used to limit and buffer the to-be-turned part 2000 when the placement device 400 is rotated to the vertical direction. The second buffer 110 can prevent the turning device 300 from turning excessively and can also buffer the turning pressure. When the cylinder pushes the placement device 400 to rotate to the upright state, the placement device 400 abuts against the second buffer 110. At this time, the air pressure of the cylinder is kept unchanged to maintain this state. After the palletizing robot moves the to-be-turned part 2000 away, the next step of operation control is performed. Furthermore, in order to buffer the rotation pressure when the flip device 300 flips back from the vertical state to the horizontal state, the flip device 300 in this embodiment further includes a first buffer 700, which is disposed on the flip seat 310 and is used to support the placement device 400 when the placement device 400 turns back from the vertical direction to the horizontal direction. Specifically, the first buffer 700 in this embodiment is a buffer beam, and a buffer block is disposed on one side of the buffer beam close to the placement device 400. Of course, it can also be replaced by other buffer structures, such as elastic members and other structures, which are not limited here.

[0045] Of course, the telescopic rod 320 can also be replaced by a connecting rod mechanism, as long as the turning device 300 can be turned 90 degrees and the turning member 2000 to be turned from a horizontal state to a vertical state, which is not limited here. In order to achieve a smooth turning of the turning device 300, the power of the driving member 240 that drives the connecting rod to rotate needs to be controlled according to the rotation position of the connecting rod.

[0046] Please continue reading Figure 3 and Figure 4The placing device 400 in this embodiment includes a roller frame 410, a push plate 420, a pallet 430 and a moving assembly 440. The moving assembly 440 and the pallet 430 are arranged on the roller frame 410. The push plate 420 is connected to the moving assembly 440. The moving assembly 440 can drive the push plate 420 to move relative to the roller frame 410 to approach or move away from the pallet 430. The push plate 420 and the pallet 430 are used together to clamp or release the part to be flipped 2000. The roller frame 410 is hinged to the flip seat 310, and the roller frame 410 is hinged to the telescopic rod 320. Specifically, the roller frame 410 in this embodiment is installed on the flip seat 310 through a flip shaft and a bearing seat. In order not to affect the subsequent palletizing robot to carry the part to be flipped 2000, the push plate 420 and the pallet 430 in this embodiment are both flat plates arranged vertically on the roller frame 410. Of course, the structural shapes of the push plate 420 and the support plate 430 may also be changed according to the actually clamped flipped object 2000 and the actual handling conditions, which is not limited here.

[0047] In order to ensure the long-term stable operation of the flip device 1000 and facilitate maintenance, the moving assembly 440 in this embodiment includes a mounting member 441 and a rodless cylinder 442, the mounting member 441 is connected to the roller frame 410, the rodless cylinder 442 includes a cylinder 4421 and a first slider 4422, the cylinder 4421 is connected to the roller frame 410 through the mounting member 441; the first slider 4422 is movably connected to the cylinder 4421, the first slider 4422 is connected to the push plate 420, and the first slider 4422 can drive the push plate 420 to move along the cylinder 4421 to approach or move away from the support plate 430. The cylinder has high working accuracy and environmental adaptability, can stably output instantaneous pressure and flow control, and is suitable for various mechanical equipment. The cylinder can work stably in complex environments such as high temperature, low temperature, humidity, and dryness to ensure production continuity. Its sturdy and durable design allows it to maintain excellent performance when subjected to heavy loads and high-frequency actions. Its good sealing performance can ensure the long-term stable operation of mechanical equipment. Specifically, the number of rodless cylinders 442 in this embodiment is two, and the two rodless cylinders 442 are arranged in parallel and spaced apart on the roller frame 410. Of course, the rodless cylinders 442 can also be replaced by a linear motion mechanism such as a driving member 240, a guide rail, and a slider, as long as the push plate 420 can be driven to move toward or away from the support plate 430 and can clamp or release the flipped member 2000. The specific type of moving assembly 440 is not limited here.

[0048] In addition, in order to ensure the stability of the movement of the push plate 420, the moving assembly 440 in this embodiment further includes an auxiliary guide rail 443 and a second slider 444. The auxiliary guide rail 443 is arranged on the roller frame 410 and is parallel to the cylinder barrel 4421. The auxiliary guide rail 443 is connected to the push plate 420 through the second slider 444. Of course, the auxiliary guide rail 443 can also be replaced with a structure with a slide groove, and the second slider 444 moves in the slide groove, which can also assist the rodless cylinder 442 to drive the push plate 420 to move toward or away from the support plate 430.

[0049] In order to reduce the friction between the to-be-turned part 2000 and the roller frame 410 and prevent the to-be-turned part 2000 from being lost, please refer to Figure 3 and Figure 4 , and combined with Figure 1 The placement device 400 in this embodiment further includes a rubber-coated roller group 450, which is arranged on the roller support frame 410 and parallel to the moving direction of the push plate 420. The rubber-coated roller group 450 includes a roller mounting frame and a plurality of rollers, the roller mounting frame is arranged on the roller support frame 410, the roller mounting frame is a hollow frame with an open side, and a plurality of rollers are arranged in the roller mounting frame at intervals, and when the to-be-turned member 2000 is installed on the placement device 400, the surface of the to-be-turned member 2000 contacts the plurality of rollers.

[0050] In order to facilitate monitoring whether the push plate 420 and the support plate 430 clamp the part to be flipped 2000, a pressure sensor 500 is provided on the push plate 420 in this embodiment. The part to be flipped 2000 is hoisted between the push plate 420 and the support plate 430 on the placement device 400, and the air port of the rodless cylinder 442 is supplied with air, and the first slider 4422 drives the push plate 420 to move, pushing the part to be flipped 2000 to translate on the rubber-coated roller group 450, and the pressure sensor 500 detects the pressure between the push plate 420 and the part to be flipped 2000. When the pressure reaches the set value, that is, the push plate 420 pushes the part to be flipped 2000 to press the support plate 430, the air pressure of the rodless cylinder 442 is kept unchanged, and the signal is fed back to the external controller, and the external controller transmits the signal to the rotating device 200, indicating that the rotating device 200 can proceed to the next step.

[0051] Please continue reading Figure 3 and Figure 4 , and combined with Figure 1The rotating device 200 in this embodiment includes a rotating frame 210, a first gear 220, a second gear 230 and a driving member 240. The rotating frame 210 is rotatably connected to the base 100. The first gear 220 is sleeved outside the rotating frame 210. The second gear 230 is transmission-connected to the first gear 220. The driving member 240 is connected to the second gear 230. The driving member 240 is used to drive the second gear 230 to rotate. Specifically, the driving member 240 is connected and fixed to the base 100 through the driving member 240 mounting plate. The driving member 240 in this embodiment is mounted on the driving member 240 mounting plate by threaded fasteners such as bolts. The rotating frame 210 is mounted on the base 100 through a bearing. Specifically, the rotating frame 210 is mounted on the base 100 through two radial ball bearings and one thrust ball bearing. The first gear 220 is fixed to the lower end of the rotating frame 210 by screws. Of course, the driving member 240 can also be connected and fixed to the base 100 through other mounting structures and connection methods, such as clamping, etc., which are not limited here.

[0052] In order to facilitate the control of the rotation speed, the driving member 240 in this embodiment is a servo motor. In order to reduce the transmission speed of the motor output end to the rotating frame 210, the number of teeth of the first gear 220 in this embodiment is greater than the number of teeth of the second gear 230. In addition, in order to further reduce the rotation speed of the motor output, a reducer is also provided between the driving member 240 and the second gear 230 in this embodiment. In order to facilitate installation while ensuring deceleration, the reducer in this embodiment is an angular planetary reducer.

[0053] In addition, in order to facilitate the flip device 300 to know that the rotating device 200 has been rotated to the right position so that it can perform the next rotation action, an angle sensor is provided on the rotating frame 210 in this embodiment. Specifically, the angle sensor monitors the rotation angle of the rotating frame 210. When the angle reaches 90°, the rotation action is completed, and this signal is transmitted to the cylinder solenoid valve of the flip device 300, and then the cylinder drives the roller frame 410 to rotate. Of course, the rotation angle can be 45°, 180°, etc. in addition to 90°, which is not limited here.

[0054] According to a flipping device 300 provided in this embodiment, its working principle is as follows:

[0055] When the part 2000 to be flipped is transported to the flipping device 1000 and fixed to the placement device 400, the rotating device 200 rotates in the horizontal plane, thereby driving the placement device 400 and the flipping device 300 to rotate a certain angle in the horizontal plane, and then the telescopic rod 320 of the flipping device 300 retracts and drives the placement device 400 to rotate 90°, from the horizontal state to the vertical state. When the part 2000 to be flipped on the placement device 400 is removed by other equipment such as a stacking robot, the flipping device 300 is turned back from the vertical state to the horizontal state, and the telescopic rod 320 extends. The rotating device 200 turns back to the initial state, and all devices are restored to the initial state so that the next part 2000 to be flipped can be flipped. The angle of rotation of the rotating device 200 is determined according to the actual working situation, as long as the rotating device 200 can rotate the placement device 400 and the flipping device 300 to a position that is convenient for the next step. The rotating device 200 in this embodiment can rotate 360° in the horizontal plane.

[0056] That is, the workpiece 2000 to be flipped is hoisted onto the flipping device 300, and air is supplied from the air port of the rodless cylinder 442. The first slider 4422 drives the push plate 420 to push the workpiece 2000 to be flipped to move horizontally on the rubber-coated roller group 450. The pressure sensor 500 monitors the pressure between the push plate 420 and the workpiece 2000 to be flipped. When the pressure reaches the set value (that is, the workpiece 2000 to be flipped presses the support plate 430), the air pressure is kept unchanged, the clamping action is completed, and this signal is transmitted to the servo motor; the servo motor drives the rotating frame 210 to rotate horizontally, and the angle sensor monitors the rotation angle of the rotating frame 210. When the angle reaches 90 degrees, the rotation action is completed, and this signal is transmitted to the cylinder solenoid valve; the cylinder drives the roller frame 410 to rotate, and the position sensor 600 monitors the change of the cylinder position. The signal is compared with the set value to control the flow direction and pressure of the air source. When the cylinder is started, a pulling force is gradually generated on the push rod, and the pulling force is gradually reduced after the flipping piece 2000 starts to flip. When the feedback signal of the position sensor 600 exceeds the set value, the air source direction of the cylinder is changed through the solenoid valve to gradually generate pressure on the push rod until the lower end of the roller frame 410 hits the second buffer 110, and the air pressure is kept unchanged. At this time, the flipping piece 2000 is in an upright state; finally, the stacking robot grasps the flipping piece 2000, and the rodless cylinder 442 supplies air in the reverse direction to drive the push plate 420 to release the flipping piece 2000, and the stacking robot moves the flipping piece 2000 away, the cylinder drives the roller frame 410 to lie flat, and the servo motor drives the rotating frame 210 to reverse to the initial position to complete a flipping operation.
