DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-7 This application is described in further detail.

[0038] The embodiment of the present application discloses an automatic rotating material discharging and replacing device.

[0039] Reference Figure 1 and Figure 2 An automatic rotating material discharge and replacement device includes a frame 1, a robotic arm 2 installed on the frame 1, and a rotating frame 3. The rotating frame 3 is rotatably connected to the frame 1, and a plurality of fixed components 5 for fixing cloth rolls are evenly arranged on the rotating frame 3 around its own rotation axis. The fixed component 5 is rotatably connected to the rotating frame 3 so that the cloth roll can be unrolled after being fixed. The robotic arm 2 is used to grab the cloth roll and place the cloth roll on the fixed component 5. After the robotic arm 2 places the cloth roll on the fixed component 5, one end of the cloth roll is pulled by the traction device of the wet wipes production and packaging equipment to achieve unrolling. The position on the rotating frame 3 corresponding to the cloth roll in use is defined as the working position 121. Rotating the rotating frame 3 can make multiple fixed components 5 correspond to the working position 121 in sequence, realize cyclic loading, reduce the labor burden of the staff, and improve the production efficiency of wet wipes.

[0040] Reference Figure 1 and Figure 2The rotating frame 3 can be symmetrically arranged in two groups about a plane perpendicular to its own rotation axis, so as to supply materials to two wet wipes production equipment, further improving the wet wipes production efficiency.

[0041] Reference Figure 2 and Figure 3 In this embodiment, the fixed assembly 5 is set to 3 groups, and the rotating frame 3 is correspondingly set to be a Y-shaped frame formed by three supporting rods 31 connected to each other. Under normal conditions (i.e., the cloth roll is normally fed to the wet wipes production and packaging equipment), two groups of the fixed assembly 5 are arranged at intervals along the vertical direction and are located on the side close to the wet wipes production and packaging equipment, and the other group is located on the side away from the wet wipes production and packaging equipment. Figure 1 For the convenience of description, the area where the two groups of fixed components 5 are located near the wet wipes production and packaging equipment is defined as the feeding area 12, and the area where the fixed components 5 are located away from the wet wipes production and packaging equipment is defined as the loading area 11. The mechanical arm 2 is installed on the rotating frame 3 near the loading area 11 to facilitate loading. At the same time, the mechanical arm 2 has a wider operating space to reduce the interference between the mechanical arm 2 and other devices.

[0042] Reference Figure 2 and Figure 3 The frame 1 is provided with a driving assembly 4 for driving the rotating frame 3 to rotate. The driving assembly 4 includes a large gear 41 fixedly connected to the rotating frame 3, and a plurality of small gears 42 rotatably connected to the frame 1 and meshing with the large gear 41. The driving assembly 4 also includes a driving member 43 for driving the small gear 42 to rotate. In this embodiment, the driving member 43 is a servo motor. The small gear 42 is connected to the output shaft of the servo motor. The rotation of the output shaft of the servo motor drives the small gear 42 to rotate and then drives the large gear 41 to rotate. The arrangement of multiple small gears 42 and multiple servo motors increases the force driving the large gear 41 to rotate, and improves the stability of the rotation of the rotating frame 3.

[0043] Reference Figure 2 and Figure 3 , a sensor (not shown in the figure) for detecting the position of the rotating frame 3 is arranged at the position of the frame 1 corresponding to the loading area 11. During the cloth roll replacement process, the rotating frame 3 rotates, and when the support rod 31 moves to the specified position of the loading area 11, the sensor receives the signal and transmits the signal to the industrial computer, thereby controlling the rotating frame 3 to stop rotating. This facilitates the manipulator to load materials on multiple fixed components 5 in sequence.

[0044] A sensor for detecting the diameter of the cloth roll is provided at a position corresponding to the working position 121 on the frame 1. By judging the diameter of the cloth roll, the timing for replacing the cloth roll can be determined.

[0045] Reference Figure 3 and Figure 4In this embodiment, the fixed component 5 is a gas expansion shaft 51, and the frame 1 is provided with an air supply component 9 for supplying air to the gas expansion shaft 51. The air supply component 9 includes a fixed shaft 91 and a rotating ring 92, and the fixed shaft 91 is fixedly connected to the frame 1 by screws. The rotating ring 92 is a circular ring structure, and the rotating ring 92 is rotatably sleeved on the fixed shaft 91 around its own circumference.

[0046] Reference Figure 4 and Figure 5 , the rotating ring 92 is fixedly connected to the rotating frame 3. A plurality of annular grooves 93 corresponding to the number of the inflation shafts 51 are arranged on the inner side wall of the rotating ring 92, and the plurality of annular grooves 93 are arranged at intervals along the length direction of the rotating ring 92. A gas channel 94 is arranged on the fixed shaft 91, and a plurality of groups of gas channels 94 are arranged corresponding to the annular grooves 93, and each group includes two gas channels 94. An opening is formed at one end of the gas channel 94 at a position corresponding to the annular groove 93 (that is, the gas channel 94 is connected to the annular groove 93), and an opening is formed at the other end at a position away from the rotating ring 92 on the side wall of the fixed shaft 91. A quick connector is installed at one end of the gas channel 94 away from the rotating ring 92 to facilitate connection with the air pipe. In this embodiment, one of the gas channels 94 is connected to the inflation device, and the other is connected to the exhaust device. By controlling the operation of different devices, positive pressure or negative pressure can be generated in the annular groove 93. A connecting air hole 95 communicating with the annular groove 93 is provided on the outer side wall of the rotating ring 92 . The connecting air hole 95 is connected to the air nozzle of the air expansion shaft 51 through a pipeline, so as to realize the expansion and contraction of the air expansion shaft 51 .

[0047] Reference Figure 2 and Figure 6 , a cloth receiving device 6 is also provided on the frame 1, and the cloth receiving device 6 is located at a position where the feeding area 12 is far away from the loading area 11. The cloth receiving device 6 includes a pressing component 62 and a cutting component 61, and the cutting component 61 is located between the pressing component 62 and the loading area 11. In this embodiment, the area corresponding to the fixing component 5 located at the top in the feeding area 12 is the working position 121, and the area corresponding to the fixing component 5 located at the bottom is the preparation position 122. The original roll 13 is defined as the original roll 13, and the spare roll 14 is defined as the spare roll 14. The cutting component 61 is used to cut the cloth on the original roll 13. During the production process of wet wipes, the end of the spare roll 14 is set below the pressing component 62, and the original roll 13 passes over the end of the spare roll 14 after unwinding. When the cloth roll needs to be replaced, the cutting component 61 cuts off the cloth on the original roll 13, and then the pressing component 62 applies a force toward the tail of the cloth on the original roll 13 to make it close to the end of the spare roll 14. The end of the spare roll 14 is pre-pasted with adhesive tape. When the ends of the two cloths are close to each other, the adhesive tape bonds and connects the two cloths, thereby realizing automatic cloth connection and further improving the working efficiency of the wet wipes.

[0048] Reference Figure 2 and Figure 6A lifting platform 7 fixedly connected to the frame 1 is provided below the cloth receiving device 6. The lifting platform 7 is used to place the end of the spare roll 14, and to provide support when the cloth of the original roll 13 is close to the cloth of the spare roll 14, thereby improving the effect of the butt joint of the two sections of cloth.

[0049] Reference Figure 2 and Figure 6 The cutting assembly 61 includes an upper knife 611, a lower knife 613 and a rotating shaft 612. The axis of the rotating shaft 612 is parallel to the axis of the air inflation shaft 51. The rotating shaft 612 rotates around its own axis and is connected to the frame 1. The upper knife 611 is installed on the rotating shaft 612. The rotation of the rotating shaft 612 can drive the upper knife 611 to rotate. The lower knife 613 is located below the upper knife 611. The cloth on the original roll 13 passes between the upper knife 611 and the lower knife 613. Rotating the rotating shaft 612 can make the upper knife 611 coincide with the lower knife 613, thereby achieving the cutting of the cloth.

[0050] Reference Figure 2 and Figure 6 , one end of the lower knife 613 is rotatably connected to the frame 1, and the lower knife 613 can be rotated to make the lower knife 613 parallel or perpendicular to the rotating shaft 612. When the lower knife 613 is perpendicular to the rotating shaft 612, the lower knife 613 is located on the side of the upper knife 612, and the cloth roll located at the preparation position 122 can move upward. When the lower knife 613 is parallel to the rotating shaft 612, the side of the upper knife 611 away from the rotating shaft 612 can match the lower knife 613 to cut the cloth. Figure 7 A brush 614 is fixedly arranged below the lower knife 613, and the brush 614 can abut against the lifting platform 7, so as to support the end of the cloth on the spare roll 14 and improve the stability of the two sections of cloth during the docking process.

[0051] Reference Figure 2 and Figure 6 The pressing assembly 62 includes a sliding frame 621 and a pressure roller 622. The pressure roller 622 is arranged in a direction parallel to the inflatable shaft 51. The pressure roller 622 is rotatably connected to the sliding frame 621. The sliding frame 621 is slidably connected to the frame 1. The sliding sliding frame 621 can drive the pressure roller 622 to move, so that the pressure roller 622 is close to the cloth on the spare roll 14 to achieve the docking of two sections of cloth. In this embodiment, the sliding frame 621 is driven by a cylinder.

[0052] Reference Figure 2, a power assist component 8 is also provided on the frame 1, and the power assist component 8 is located on the frame 1 near the working position 121, and is located above the fixed component 5 of the working position 121. The power assist component 8 includes a mounting plate 81, a pulley 82, and a belt 83. The mounting plate 81 is a rectangular structure as a whole, and one end of the mounting plate 81 is rotatably connected to the frame 1, and the rotation axis of the mounting plate 81 is parallel to the axis of the inflatable shaft 51. The pulley 82 is rotatably connected to the mounting plate 81, and two are arranged at intervals along the length direction of the mounting plate 81. The belt 83 is wound around the two pulleys 82, and the belt 83 is tangential to and abuts against the original roll 13. When the belt 83 rotates, it can drive the original roll 13 to rotate under the action of friction, thereby reducing the deformation or breaking of the cloth on the original roll 13 due to tension.

[0053] In this embodiment, under the action of the gravity of the assisting assembly 8, the mounting plate 81 has a tendency to rotate downward, so that the belt 83 can abut against the cloth roll. In other embodiments, the mounting plate 81 can be driven by a cylinder, the outer shell of the cylinder is rotatably connected to the frame 1, the piston rod of the cylinder is rotatably connected to the mounting plate 81, and the cylinder piston rod can drive the mounting plate 81 to rotate by extension. In other embodiments, the mounting plate 81 can also be driven by other driving structures, such as a motor, a rotary cylinder, etc.

[0054] Reference Figure 2 The position corresponding to the preparation position 122 on the frame 1 is also provided with a booster assembly 8, and the booster assembly 8 corresponding to the preparation position 122 is located below the fixed assembly 5. The booster assembly 8 corresponding to the preparation position 122 mainly serves to lift the spare roll 14, so as to facilitate the spare roll 14 to move to the working position 121, and the booster assembly 8 can drive the spare roll 14 to rotate actively. Here, since the booster assembly 8 is located below the cloth roll pair, the mounting plate 81 is driven by a cylinder.

[0055] The implementation principle of an automatic rotating material discharge and replacement device in an embodiment of the present application is as follows: during the production process of wet wipes, the robotic arm 2 automatically grabs the cloth roll and places it on the air inflation shaft 51 located in the loading area 11. When the cloth roll on the air inflation shaft 51 located in the working position 121 is used up, the rotating frame 3 rotates to drive the spare roll 14 to automatically move to the working position 121, thereby realizing automatic replacement of the cloth roll, thereby improving the production efficiency of the wet wipes.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
