DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example

[0029] See also Figure 1-7 The present invention provides the following technical solutions: an intelligent paper tube bagging machine, comprising a bottom plate 1, the bottom plate 1 is a rectangular plate body, four first columns 2 are vertically fixed at the corners of the bottom plate 1, a rectangular frame 3 is fixed on the top support of the four first columns 2, two translation guide rails 4 are fixed in parallel on the top surfaces of both sides of the rectangular frame 3, translation sliders 5 are movably embedded on the two translation guide rails 4, the top supports of the two translation sliders 5 are connected with an angle beam 6, one end of the angle beam 6 is fixedly installed with a first servo transmission pair 7, and the first servo transmission pair 7 is fixedly installed on the first servo transmission pair 7. The movable pair 7 is connected to the middle part of the translation guide rail 4, a lifting slide 8 is fixedly installed in the middle part of the angle beam 6, a lifting guide rail 9 is movably embedded in the lifting slide 8, a second servo transmission pair 10 is fixedly installed in the middle part of the angle beam 6, the second servo transmission pair 10 is connected to the middle part of the lifting guide rail 9, a universal connecting plate 11 is fixedly provided at the bottom end of the lifting guide rail 9, and a paper tube grabbing mechanism is connected to the bottom end of the universal connecting plate 11, which is an outer circle grabbing mechanism 12 or an end face grabbing mechanism 13 or a suction cup suction mechanism 14.

[0030] In this embodiment, the outer circle grasping mechanism 12 clamps the paper tube from the outer circle surface of the paper tube, the end face grasping mechanism 13 clamps the paper tube from both ends of the paper tube, and the suction cup suction mechanism 14 sucks the paper tube from the top surface of the paper tube through a vacuum suction cup. All three are one of the automatic grasping methods of the paper tube, and can be flexibly applied according to actual needs. After the three each grasp a corresponding number of paper tubes, the second servo transmission pair 10 drives the outer circle grasping mechanism 12 or the end face grasping mechanism 13 or the suction cup suction mechanism 14 to lift and lower the paper tube through the lifting guide rail 9. At this time, the first servo transmission pair 7 drives the angle beam 6 to move horizontally along the two translation guide rails 4, driving the lifted paper tube to move left and right, and transferring the paper tube. Among them, the first servo transmission pair 7 and the second servo transmission pair 10 are screw transmission components or synchronous belt transmission components, which can perform precise displacement of the angle beam 6 and the lifting guide rail 9.

[0031] Specifically, four second columns 15 are vertically fixed on the sides of the bottom plate 1, and the top ends of the four second columns 15 support and connect the bottom surfaces of the two sides of the rectangular frame 3. A belt conveyor 16 is fixedly installed in the middle of the four second columns 15. The belt conveyor 16 is arranged directly below the paper tube grasping mechanism, and a conveying motor 17 is fixedly installed at one end of the belt conveyor 16. A crossbeam 18 is fixed between two first columns 2 located on the same side, and bag mouth fixing clamps 19 are fixedly installed at both ends of the two crossbeams 18. The two pairs of bag mouth fixing clamps 19 are symmetrically fixed on both sides of the paper tube grasping mechanism.

[0032] In this embodiment, two relatively arranged bag opening fixing clamps 19 fix and open the opening of the paper tube packaging bag, and the paper tubes to be bagged are placed and conveyed on the belt conveyor 16. When the paper tubes reach the terminal or the set position of the belt conveyor 16 under the transmission of the conveying motor 17, the second servo transmission pair 10 drives the lifting guide rail 9 to descend, and the outer circle grabbing mechanism 12 or the end surface grabbing mechanism 13 or the suction cup suction mechanism 14 at the bottom of the lifting guide rail 9 respectively grabs the paper tubes placed on the top surface of the belt conveyor 16. After the three grabbing mechanisms grab the set number of paper tubes, the second servo transmission pair 10 lifts the grabbed paper tubes through the lifting guide rail 9 and the three grabbing mechanisms, and then the first servo transmission pair 7 drives the lifting guide rail 9 and the grabbed paper tubes to move horizontally along the two translation guide rails 4, and transfers the paper tubes to the two bag opening fixing clamps 19. The top of the packaging bag is clamped and fixed between the fixed clamps 19, and then the second servo transmission pair 10 drives the lifting guide rail 9 and the grasped paper tube to descend to the bottom of the packaging bag again. At this time, the outer circle grasping mechanism 12 or the end face grasping mechanism 13 or the suction cup suction mechanism 14 releases the grasped paper tube, and the paper tube falls into the bottom of the packaging bag. Then the second servo transmission pair 10 drives the lifting guide rail 9 to lift again, and the first servo transmission pair 7 drives the lifting guide rail 9 to return to move to just above the belt conveyor 16. At this time, the second automatic bagging cycle starts. The second servo transmission pair 10 can control the distance of each material drop during the bagging process. Specifically, for each bagging cycle, the material drop stroke is reduced by one paper tube diameter, and this is done until the packaging bag is full, then it is restarted, the original bagging data is cleared, and the bagging operation process is repeated again.

[0033] Specifically, the outer circle grasping mechanism 12 includes a slide connecting frame 1201, eight tube-removing cylinders 1202 are vertically fixed to the top of the slide connecting frame 1201, and eight elastic clips 1203 are fixed to the bottom of the slide connecting frame 1201. The middle of the top surface of the eight elastic clips 1203 is provided with a through hole, and the telescopic axes of the eight tube-removing cylinders 1202 all pass through the corresponding through holes of the elastic clips 1203.

[0034] In this embodiment, the bottom end of the lifting guide rail 9 is fixed to the outer circle grasping mechanism 12 through the universal connecting plate 11, and when the outer circle grasping mechanism 12 descends to the top surface of the belt conveyor 16, the eight elastic clips 1203 automatically engage with the paper tubes arranged on the top surface of the belt conveyor 16. At this time, the paper tubes move to the inner cavity of the packaging bag along with the lifting guide rail 9 and the angle beam 6, and then high-pressure gas is introduced into the eight tube-detaching cylinders 1202. The high-pressure gas pushes the telescopic shaft of the tube-detaching cylinder 1202 forward, and pushes out the paper tubes engaged in the elastic clips 1203, thereby realizing the separation of the two. In this way, the loading and unloading work process of the outer circle grasping mechanism 12 is realized.

[0035] Specifically, the end face grasping mechanism 13 includes a bending angle plate 1301, and a double-axis cylinder 1302 is horizontally fixedly installed in the middle of the top surface of the bending angle plate 1301. The top end of the telescopic axis of the double-axis cylinder 1302 is connected to a clamping plate 1303, and the clamping plate 1303 is arranged parallel to the side of the bending angle plate 1301.

[0036] In this embodiment, when in use, the clamping plate 1303 is displaced under the drive of the double-outlet shaft cylinder 1302, and the distance between the clamping plate 1303 and the side of the bent angle plate 1301 changes. When the distance between the clamping plate 1303 and the side of the bent angle plate 1301 becomes larger, the end surface grasping mechanism 13 descends to the two sides of the end of the paper tube conveyed on the belt conveyor 16 through the lifting guide rail 9, and then the double-outlet shaft cylinder 1302 retracts, so that the inner side of the clamping plate 1303 and the bent angle plate 1301 clamps the two ends of the eight paper tubes, realizing the end clamping, and then the end surface grasping mechanism 13 moves to the inner cavity of the packaging bag along with the lifting guide rail 9 and the angle beam 6. At this time, high-pressure gas is introduced into the double-outlet shaft cylinder 1302, and the double-outlet shaft cylinder 1302 pushes the clamping plate 1303 to loosen the two ends of the clamped paper tube, thereby realizing the loading and blanking work process of the end surface grasping mechanism 13.

[0037] Specifically, the suction cup suction mechanism 14 includes an angular connecting frame 1401, and eight vacuum tubes 1402 are equidistantly threadedly connected to the bottom end of the angular connecting frame 1401. The top ends of the eight vacuum tubes 1402 are connected to the vacuum device through air pipes, and the bottom ends of the eight vacuum tubes 1402 are all connected to contoured suction cups 1403.

[0038] In this embodiment, when the eight vacuum tubes 1402 are connected to the vacuum mechanism, the contoured suction cup 1403 grabs the surface of the paper tube by sucking it with negative pressure. When the suction cup suction mechanism 14 moves to the inner cavity of the packaging bag along with the lifting guide rail 9 and the angle beam 6, high-pressure gas is introduced into the contoured suction cup 1403 through the eight vacuum tubes 1402. The high-pressure gas pushes the eight paper tubes to separate from the contoured suction cup 1403, thereby realizing the loading and unloading work process of the suction cup suction mechanism 14.

[0039] Specifically, an electric control box 20 is fixedly installed on one side of the top of the rectangular frame 3, and two sets of servo drivers 21 and a frequency converter 22 are installed in the electric control box 20. The two sets of servo drivers 21 are electrically connected to the first servo transmission pair 7 and the second servo transmission pair 10 respectively, and the output end of the frequency converter 22 is electrically connected to the conveying motor 17.

[0040] In this embodiment, two groups of servo drivers 21 adopt DKC-Y220 dual-axis servo motor controllers, which respectively send set drive currents or pulses to the first servo transmission pair 7 and the second servo transmission pair 10, thereby driving the angle beam 6 to perform fixed stroke horizontal displacement and driving the lifting guide rail 9 to perform variable stroke lifting displacement; the frequency converter 22 adopts a VFD-V precision drive frequency converter, which can well control the rotation speed of the conveying motor 17, and then control the speed of the belt conveyor 16 to convey the paper tube, so that it matches the speed of the bagging mechanism of the present invention.

[0041] In this embodiment, the first servo transmission pair 7, the second servo transmission pair 10, the servo driver 21 and the frequency converter 22 are known technologies that have been disclosed and widely used in industrial production and daily life.

[0042] The working principle and use process of the present invention are as follows: the paper tubes to be bagged are placed and conveyed on the belt conveyor 16. When the paper tubes reach the terminal or the set position of the belt conveyor 16 under the transmission of the conveying motor 17, the second servo transmission pair 10 drives the lifting guide rail 9 to descend, and the outer circle grabbing mechanism 12 or the end face grabbing mechanism 13 or the suction cup suction mechanism 14 at the bottom of the lifting guide rail 9 grabs the paper tubes placed on the top surface of the belt conveyor 16 respectively. After the three grabbing mechanisms grab the set number of paper tubes, the second servo transmission pair 10 lifts the grabbed paper tubes through the lifting guide rail 9 and the three grabbing mechanisms, and then the first servo transmission pair 7 drives the lifting guide rail 9 and the grabbed paper tubes to move horizontally along the two translation guide rails 4, and transfers the paper tubes to the two bag opening fixing clamps 19 for clamping and fixing. The top of the specified packaging bag is then driven by the second servo transmission pair 10, which drives the lifting guide rail 9 and the captured paper tube to descend to the bottom of the packaging bag again. At this time, the outer circle grasping mechanism 12 or the end face grasping mechanism 13 or the suction cup suction mechanism 14 releases the captured paper tube, and the paper tube falls into the bottom of the packaging bag. Then the second servo transmission pair 10 drives the lifting guide rail 9 to lift again, and the first servo transmission pair 7 drives the lifting guide rail 9 to return to move directly above the belt conveyor 16. At this time, the second automatic bagging cycle starts. The second servo transmission pair 10 can control the distance of each material drop during the bagging process. Specifically, for each bagging cycle, the material drop stroke is reduced by one paper tube diameter, and this is done until the packaging bag is full. Then it is restarted, the original bagging data is cleared, and the bagging operation process is repeated again.
