[0038] Embodiment 1:

[0039] Please refer to Figures 1-5 The embodiment provides a kind of automatic loading clamp of carton blank of carton sealing machine, including support frame component 10, and first grabbing component 30, second grabbing component 40, first belt shoveling component 50, second belt shoveling component 60 and belt cutting component 20 installed on support frame component 10.

[0040] Support frame component 10 mainly plays the role of supporting connection, provides installation base for other parts;The support frame component 10 includes base plate 11, the center position of the top of base plate 11 is fixed with robot connection flange 12, and robot connection flange 12 is used to install the automatic loading clamp of carton blank of carton sealing machine on the operating end of loading mechanical arm.Base plate 11 two side end faces top are respectively fixed with first upper vertical plate 13 and second upper vertical plate 14;First upper vertical plate 13 is used to install first grabbing component 30, and second upper vertical plate 14 is used to install second grabbing component 40;

[0041] A third lower vertical plate 17 is fixed at the center of the bottom of the substrate 11, and a first lower vertical plate 15 and a second lower vertical plate 16 are symmetrically fixed on both sides of the third lower vertical plate 17. The third lower vertical plate 17 is used to install a cutting tape assembly 20, the first lower vertical plate 15 is used to install a first tape shoveling assembly 50, and the second lower vertical plate 16 is used to install a second tape shoveling assembly 60.

[0042] Reference Figure 3 As shown, the support frame assembly 10 can further include a protective cover 80, which provides protection and isolation of pollution. The protective cover 80 forms a protective space inside, which can accommodate the first grabbing assembly 30, the second grabbing assembly 40, the first tape shoveling assembly 50, the second tape shoveling assembly 60 and the cutting tape assembly 20. The bottom of the protective cover 80 is open, which does not affect the realization of the functions of the tape shoveling, cutting and feeding of the automatic box blank loading clamp of the box sealing machine.

[0043] Specifically, the first grabbing assembly 30 includes an integrated vacuum suction cup 31 and a suction cup telescopic cylinder 32. The suction cup telescopic cylinder 32 has a fixed end and a telescopic end. The fixed end of the suction cup telescopic cylinder 32 is connected with the first upper vertical plate 13. The telescopic end of the suction cup telescopic cylinder 32 is connected with an adapter plate, which provides a mounting basis for the integrated vacuum suction cup 31. The integrated vacuum suction cup 31 is connected with the telescopic end of the suction cup telescopic cylinder 32 through the adapter plate. The integrated vacuum suction cup 31 is driven by the suction cup telescopic cylinder 32 to approach or move away from the box blank. The integrated vacuum suction cup 31 grabs and releases the box blank.

[0044] The second grabbing assembly 40 is identical in structure to the first grabbing assembly 30. Those skilled in the art can understand that this will not be described again. When in use, the integrated vacuum suction cup 31 can be lifted by retracting the two sets of suction cup telescopic cylinders 32 of the first grabbing assembly 30 and the second grabbing assembly 40, so as to avoid the space around the box blank and facilitate the implementation of other processes. The integrated vacuum suction cup 31 can be extended to be in contact with the surface of the box blank by extending the two sets of suction cup telescopic cylinders 32, so as to implement the process of grabbing the box blank.

[0045] The cutting tape assembly 20 of the present embodiment is a pneumatic scissors, which is used to cut the shoveling tape 90 and complete the process of cutting the tape 90.

[0046] The first tape shoveling assembly 50 is fixed to the first lower vertical plate 15. The first tape shoveling assembly 50 includes a tape shoveling plate seat 51 and a tape shoveling plate 52. The two ends of the tape shoveling plate seat 51 form a first end and a second end, respectively. The first end is used to connect with the first lower vertical plate 15, and the second end is used to hinge with the tape shoveling plate 52. One end of the tape shoveling plate 52 forms a hinge end, and the other end forms a tape shoveling end. The hinge end is hinged with the second end, and the tape shoveling end is used to shovel the tape 90.

[0047] The shovel belt plate 52 is hinged with the shovel belt plate seat 51, so that the shovel belt plate 52 can rotate at a certain angle relative to the shovel belt plate seat 51, and the shovel belt end of the shovel belt plate 52 is normally located closer to the box blank. For example, when taking materials downward, the shovel belt plate 52 can be deflected downward under the action of gravity, and when taking materials to the side, the shovel belt plate 52 can be deflected to the side by setting an elastic member, and a person skilled in the art can implement it according to actual needs. When the first shovel belt assembly 50 approaches the box blank, the surface of the box blank first contacts the shovel belt end of the shovel belt plate 52, and when the first shovel belt assembly 50 continues to move towards the box blank, the shovel belt plate 52 rotates relative to the shovel belt plate seat 51 under the pushing of the box blank. Thus, a more flexible contact is provided between the shovel belt end of the shovel belt plate 52 and the surface of the box blank, which avoids damaging the box blank during the feeding process and improves the fit between the shovel belt end of the shovel belt plate 52 and the box blank, greatly improving the success rate of the shovel belt.

[0048] Further, the first end and the second end of the shovel belt plate seat 51 form a positioning surface 511, which is formed on the upper surface of the shovel belt plate seat 51 and provides a basis for positioning and clamping fixing of the binding belt 90. A first sensor is fixed above the positioning surface 511. The first sensor is a travel switch sensor, which is used to detect the positioning of the binding belt 90. When the binding belt is scooped up to the positioning surface 511, the travel switch is triggered to send a positioning signal, and the post-process is performed through the positioning signal.

[0049] The first shovel belt assembly 50 further comprises a binding belt positioning structure 53, which comprises a binding belt positioning cylinder 531 and a positioning plate 532. The binding belt positioning cylinder 531 has a fixed end and a telescopic end. The fixed end of the binding belt positioning cylinder 531 is fixed to the bottom of the base plate 11. The telescopic end of the binding belt positioning cylinder 531 is connected with the positioning plate 532, and the positioning plate 532 is arranged close to the positioning surface 511. The binding belt is clamped between the positioning plate 532 and the positioning surface 511 by driving the positioning plate 532 close to the positioning surface 511 through the binding belt positioning cylinder 531.

[0050] The upper surface of the shovel belt plate 52 of the embodiment forms a guide surface 512, which is a transition surface inclined downward from the hinged end to the shovel end of the shovel belt plate 52, and can be an arc surface or a plane. The binding belt 90 is better guided from the shovel end to the positioning surface 511 through the guide surface 512. The guide surface 512 has a first deflection angle, which is preferably 0°-45°. When the guide surface 512 rotates to the first deflection angle, the end surface of the hinged end of the shovel belt plate 52 abuts against the end surface of the second end of the shovel belt plate seat 51, thereby limiting further rotation of the shovel belt plate 52.

[0051] The first shoveling and banding assembly further comprises a resilient member 54, which is a torsion spring in this embodiment, arranged between the shoveling and banding plates 52, one end of the torsion spring abutting against the end face of the hinged end of the shoveling and banding plate 52, and the other end abutting against the second end face, so as to provide an elastic force for driving the guide surface 512 to return to the first deflection angle, that is, to provide a resilient force for the shoveling and banding plate 52

[0052] Further, the first shoveling and banding assembly 50 further comprises a first pressure box roller 55 and a second pressure box roller 56, which are respectively rotatably connected to the two sides of the shoveling and banding plate seat 51, and are used to rollingly contact the surface of the box blank. The number of the first pressure box roller 55 and the second pressure box roller 56 in this embodiment is 2. By arranging the pressure box rollers, the automatic box blank feeding clamp of the sealing and boxing machine in this embodiment is formed in rolling contact with the box blank, so as to avoid mutual friction and damage to the surface of the box blank.

[0053] The second shoveling and banding assembly 60 is identical in structure to the first shoveling and banding assembly 50, and both are symmetrically arranged on the opposite sides of the cutting and banding assembly 20 through the first lower vertical plate 15 and the second lower vertical plate 16, and jointly act to shovel and send the binding band 90 to the cutting position of the cutting and banding assembly 20. Those skilled in the art can understand that this will not be described here.

[0054] When the shoveling and banding process is performed, the shoveling and banding plate 52 is driven by the feeding mechanical arm and the elastic force of the torsion spring to shovel the binding band 90 on the box blank to the positioning surface 511 of the shoveling and banding plate seat 51. During the movement of the feeding mechanical arm, the first pressure box roller 55 and the second pressure box roller 56 are responsible for positioning the position of the uppermost carton, so as to avoid the scattering of the carton stack.

[0055] Further, the automatic box blank feeding clamp of the sealing and boxing machine in this embodiment further comprises a control assembly, which comprises a main control system installed with a control program, the first sensor 71 and the second sensor 72. Specifically, the first sensor 71 is in signal connection with the main control system, and sends a first sensing signal to the main control system when the binding band 90 is shoveled to the positioning surface 511.

[0056] The second sensor 72 is arranged at the bottom of the base plate 11, and is in signal connection with the main control system. The second sensor 72 in this embodiment is a diffuse reflection sensor, and is used to detect the height of the box blank and provide a height coordinate for the feeding mechanical arm.

[0057] The control assembly further comprises a first control valve 73, a second control valve 74, a third control valve 75 and a fourth control valve 76 mounted on the base plate 11; wherein the first control valve 73, the second control valve 74 and the third control valve 75 are all two-position three-way electromagnetic valves responsible for controlling the air source of the suction cup telescopic cylinder 32, the binding tape positioning cylinder 531 and the pneumatic scissors; the fourth control valve 76 is a two-position five-way electromagnetic valve responsible for controlling the air source of the integrated vacuum suction cup 31.

[0058] Specifically, the suction cup telescopic cylinder 32 has a first air source interface connected with the first control valve 73, the first control valve 73 is electrically connected with the main control system; the binding tape positioning cylinder 531 has a second air source interface connected with the second control valve 74, the second control valve 74 is electrically connected with the main control system; the pneumatic scissors have a third air source interface connected with the third control valve 75, the third control valve 75 is electrically connected with the main control system; the integrated vacuum suction cup 31 has a fourth air source interface connected with the fourth control valve 76, the fourth control valve 76 is electrically connected with the main control system.

[0059] Based on the above structure, the use method of the box blank automatic feeding clamp of the box sealing machine of the embodiment comprises the following steps:
