Description

Technical Field

[0001] The utility model relates to the technical field of a cover opening and closing gripper mechanism, and more specifically, to an open and close cap gripper mechanism for automated filling. Background Art

[0002] In the liquid packaging and automated canning production lines, it is necessary to put the liquid into an empty box, and then use a gripper mechanism to open and close the top cover. In the existing technology, the top cover is located at the bottom of the center of the gripper mechanism, and then the gripper mechanism grasps the top cover from the outside of the top cover, and then rotates and twists it. Then the gripper mechanism removes the top cover from the top of the box, and then the liquid is poured into the box. After filling, the top cover is screwed on by the gripper mechanism. However, during the removal process, the top cover may fall off due to insufficient friction between the gripper and the top cover. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an opening and closing cover gripper mechanism for automated filling, which has the advantage of preventing the top cover from falling off.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an opening and closing cover gripper mechanism for automated filling, comprising a rotating rod, and further comprising:

The mounting seat has a rotational freedom relative to the lifting sleeve. The bottom of the mounting seat is movably connected to a first plug-in rod, and the mounting seat is hinged to an articulated rod through the first plug-in rod. The bottom end of the articulated rod is movably connected to a second plug-in rod, and the bottom end of the articulated rod is hinged to an articulated seat through the second plug-in rod. The bottom end of the articulated seat is fixedly connected to an anti-sliding block. The articulated rod can rotate with the first plug-in rod as the axis, and the articulated seat can rotate with the second plug-in rod as the axis. The rotating rod has a rotational freedom relative to the lifting sleeve.

[0007] When the top cover is removed from the empty box, the rotating rod rotates, and the cylinder drives the lifting sleeve rod to move downward, thereby causing the anti-sliding block to support the top cover from the inner side of the top cover, and the supporting spring seat contracts at this time, and then the rotating rod drives the anti-sliding block to rotate, and the top cover is unscrewed from the empty box. When the top cover is separated from the box, the anti-sliding block loses its limit, thereby causing the supporting spring seat to stretch. At this time, the lifting seat is driven down by the supporting spring seat, and the lifting seat is driven to rotate toward the outside of the top cover with the fourth plug-in rod as the axis, thereby driving the anti-sliding block and the top cover to fit more closely, thereby preventing the top cover from falling from the outer surface of the anti-sliding block when the anti-sliding block removes the top cover, thereby improving the stability between the top cover and the anti-sliding block.

[0008] As a further improvement of the present invention, the top end of the rotating rod is fixedly connected to a connecting rod, and the bottom of the anti-sliding block is provided with a top cover;

[0009] The beneficial effect of adopting the above technical solution is that the connecting rod is connected to the output shaft of the external rotating motor, so that the rotating motor can drive the rotating rod at the bottom end of the connecting rod to rotate, and then the rotation of the rotating rod drives the anti-sliding block to rotate, and then when the anti-sliding block supports the top cover, it can drive the anti-sliding block to rotate and unscrew the top cover from the empty box.

[0010] As a further improvement of the present invention, the inner cavity at the top of the top cover is fixedly connected with four slot blocks, the anti-slip block is located between the four slot blocks, and the contact surface between the anti-slip block and the top cover is provided with an anti-slip groove;

[0011] The beneficial effect of adopting the above technical solution is that the anti-sliding block is limited by the four slot blocks on the top of the top cover, thereby improving the stability of the anti-sliding block when supporting the top cover outward, and then the anti-slip performance between the anti-sliding block and the top cover is improved by setting the anti-slip groove.

[0012] As a further improvement of the present invention, a third plug-in rod is plugged into the bottom of the support spring seat, and the support spring seat is connected to the lifting seat through the third plug-in rod;

[0013] The beneficial effect of adopting the above technical solution is that, through the third plug-in rod at the bottom end of the support spring seat, the support spring seat can be connected to the lifting seat through the third plug-in rod, so that the support spring seat can drive the lifting seat to move, and the angle of the articulated seat is changed through the movement of the lifting seat.

[0014] As a further improvement of the present invention, a fourth plug-in rod is plugged into the outer side of the lifting seat, and the hinged seat is hinged to the lifting seat through the fourth plug-in rod;

[0015] The beneficial effect of adopting the above technical solution is that, when the fourth plug-in rod on the outside of the lifting seat is used to change the angle of the hinged rod driven by the support spring seat, the hinged seat can be driven to rotate toward the outside of the top cover with the fourth plug-in rod as the axis, and the top cover can be supported from the inside of the top cover by the anti-sliding block.

[0016] As a further improvement of the present invention, the inner cavities of the first plug-in rod, the second plug-in rod, the fourth plug-in rod, and the third plug-in rod are all provided with locking strips;

[0017] The beneficial effect of adopting the above technical solution is that by setting the locking strip, the first plug rod, the second plug rod, the fourth plug rod and the third plug rod are limited and locked, thereby improving the stability of the first plug rod, the second plug rod, the fourth plug rod and the third plug rod when they are hinged.

[0018] As a further improvement of the present invention, a mounting rod is provided at the center of the inner cavity of the lifting seat, and the mounting rod is movably sleeved in the inner cavity at the bottom of the rotating rod;

[0019] The beneficial effect of adopting the above technical solution is that, through the installation rod in the middle of the lifting seat, the installation rod is movably connected to the inner cavity at the bottom of the rotating rod, and then the lifting seat is positioned and guided by the installation rod, thereby preventing the lifting seat and anti-sliding block and other components from shifting during use.

[0047] The working principle and use process of the utility model are as follows: the output shaft of the external rotating motor is connected to the connecting rod 2, and the lifting sleeve rod 3 is connected to the output end of the cylinder;

[0048] When the empty box needs to be filled with liquid, the cylinder is started to drive the lifting sleeve rod 3 to fall, so that the anti-sliding block 12 contacts the top cover 16 on the empty box, and the supporting spring seat 14 is in a contracted state. At this time, the top cover 16 is supported by the anti-sliding block 12, and the motor is started to drive the rotating rod 1 to rotate, which drives the lifting seat 13 to rotate, and then drives the anti-sliding block 12 to rotate. The anti-sliding block 12 is rotated to remove the top cover 16 from the empty box.

[0049] Then the cylinder is activated to drive the lifting sleeve 3 to rise. At this time, the thrust provided by the support spring seat 14 drives the hinge rod 9 to pull upward. At this time, the hinge seat 10 drives the anti-sliding block 12 to move outward with the fourth plug-in rod 19 as the axis. Then, the anti-sliding block 12 applies force from the inside to the outside to the top cover 16, so that the anti-sliding block 12 and the top cover 16 are in close contact and prevent it from falling.
