AI Technical Summary
Existing mechanical grippers require rotating to open cement bags when gripping them, causing the cement bags to fall and generate dust, which cannot meet the requirements of cleanroom production.
A lever-type gripper is adopted. The lever-type gripper is installed on the robotic arm. The finger-driven mechanism moves the gripping fingers to the underside of the cement packaging bag to lift it up. During the movement, the lever prevents the gripping fingers from retracting, thus avoiding the generation of smoke and dust.
It achieves zero smoke and dust generation when handling cement packaging bags, meeting the requirements of dust-free production.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of loading equipment technology, and in particular to a lever-type gripper for a loading machine. Background Technology
[0002] Previously, the mechanical gripper used in our automatic cement loading machine used a rotating and opening / closing gripper finger to pick up cement bags. For details of the structure, please refer to CN217229518U Automatic Loading Machine Gripper. During use, the gripper finger needs to rotate downwards to open, so it is necessary to ensure that the mechanical gripper and the lower cement bag are at a certain height. This results in the cement bag falling onto the lower cement bag when the gripper finger opens and lowers, generating some dust. With the increasingly stringent standards of cleanroom production, there is an urgent need to improve the existing gripper structure. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a lever-type gripper for a vehicle loading machine.
[0004] This utility model provides a lever-type gripper for a vehicle loading machine, comprising: a mounting frame, a lever disposed downward on one side of the mounting frame, a movable frame slidably mounted on the mounting frame, gripping fingers disposed horizontally in the movable frame, and a finger driving mechanism disposed on the mounting frame for driving the movable frame to reciprocate in the horizontal direction.
[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the lever-type gripper can be installed on a robotic arm. The robotic arm moves the lever-type gripper to one side of the roller conveyor. The finger drive mechanism moves the gripping fingers through the moving frame, so that the gripping fingers can extend into the gap between the rollers in the roller conveyor to the underside of the cement packaging bag. After moving into position, the robotic arm lifts the lever-type gripper to support the cement packaging bag. After the cement packaging bag is moved to the loading position, the finger drive mechanism reverses its action and moves the gripping fingers back through the moving frame. During the movement of the gripping fingers, the cement packaging bag is blocked by the lever, so that it is gently placed in the loading position after the gripping fingers move into position, avoiding the generation of smoke and dust.
[0006] Optionally, the finger gripper includes a connecting rod, with finger grippers spaced apart on one side of the connecting rod facing the dial plate, and a support rod on the other side of the connecting rod, the support rod being connected to the movable frame.
[0007] Optionally, the inner end of the support rod near the connecting rod is hinged to the movable frame, and a finger adjustment cylinder is provided between the outer end of the support rod and the movable frame.
[0008] Optionally, a rotating platform is provided on the top of the mounting frame, and a rotary drive motor is mounted on the rotating platform. The rotary drive motor is connected to the mounting frame for transmission.
[0009] Optionally, it also includes a horizontal beam, on which horizontal guide rails are arranged in parallel. A moving trolley is slidably arranged on the horizontal guide rails. A lifting beam is slidably arranged on the moving trolley. The lifting beam is connected to the top of the rotary table. The moving trolley is also equipped with a horizontal drive mechanism and a vertical drive mechanism. The horizontal drive mechanism is used to drive the moving trolley to reciprocate, and the vertical drive mechanism is used to drive the lifting beam to reciprocate.
[0010] Optionally, the lower edge of the dial is wavy. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.
[0019] See Figures 1-5 The present invention provides a paddle-type gripper for a loading machine, comprising: a mounting frame 1, a paddle 2 disposed downward on one side of the mounting frame 1, a movable frame 3 horizontally slidably fitted on the mounting frame 1, a gripping finger 4 horizontally disposed in the movable frame 3, and a finger driving mechanism 5 disposed on the mounting frame 1 for driving the movable frame 3 to reciprocate in the horizontal direction.
[0020] In use, the lever-type gripper can be mounted on a robotic arm. The robotic arm moves the lever-type gripper to one side of the roller conveyor. The finger drive mechanism 5 moves the gripping finger 4 through the moving frame 3, allowing the gripping finger 4 to extend through the gap between the rollers in the roller conveyor to the underside of the cement bag. After moving into position, the robotic arm lifts the lever-type gripper to support the cement bag. After moving the cement bag to the loading position, the finger drive mechanism 5 reverses its action, moving the gripping finger 4 back through the moving frame 3. During the movement of the gripping finger 4, the cement bag is blocked by the lever 2, so that after the gripping finger 4 moves into position, it is gently placed at the loading position to avoid generating dust.
[0021] In practice, the gripping finger 4 can be positioned slightly below the lower edge of the dial plate 2, or a through hole can be opened in the dial plate 2, through which the gripping finger 4 passes.
[0022] The gripper 4 includes a connecting rod 6, with finger bars 7 spaced apart on one side of the connecting rod 6 toward the turntable 2, and a support rod 8 on the other side of the connecting rod 6. The support rod 8 is connected to the movable frame 3. The width of the finger bars 7 and the gap between the finger bars 7 are adapted to the gap between the rollers in the roller conveyor.
[0023] In practice, the inner end of the support rod 8 near the connecting rod 6 is hinged to the movable frame 3, and a finger adjustment cylinder 9 is provided between the outer end of the support rod 8 and the movable frame 3. The finger adjustment cylinder 9 is hinged to both the movable frame 3 and the support rod 8 to adjust the angle of the gripping finger 4.
[0024] In practice, a rotating platform 10 is rotatably mounted on the top of the mounting frame 1, and a rotary drive motor 11 is mounted on the rotating platform 10. The rotary drive motor 11 is connected to the mounting frame 1 for transmission. When the transmission connection is achieved, a gear ring can be set on the top of the mounting frame 1 and coaxial with the rotation center of the rotating platform 10. A gear that meshes with the gear ring is set on the output shaft of the rotary drive motor 11, so that the gripper finger 4 can be rotated and adjusted by the mounting frame 1, thereby adapting to various stacking positions.
[0025] In practice, it also includes a horizontal beam 12, on which horizontal guide rails 13 are arranged in parallel. A moving trolley 14 is slidably arranged on the horizontal guide rails 13. A lifting beam 15 is vertically slidably arranged on the moving trolley 14. The lifting beam 15 is connected to the top of the rotary table 10. The moving trolley 14 is also equipped with a horizontal drive mechanism 16 and a vertical drive mechanism 17. The horizontal drive mechanism 16 is used to drive the moving trolley 14 to reciprocate, and the vertical drive mechanism 17 is used to drive the lifting beam 15 to reciprocate.
[0026] In practice, the lower edge of the lever 2 is wavy, which is adapted to the shape of the roller conveyor.
[0027] In practice, the finger drive mechanism 5, the horizontal drive mechanism 16, and the vertical drive mechanism 17 can all be implemented using a motor, gear, and rack structure.
[0028] During the loading process, such as Figure 5 The transport vehicle shown is parked between two roller conveyors 18. Cement bags are conveyed to roller conveyors 18 via belt conveyor 19 and then to the gripping position by roller conveyors 18. The moving trolley 14 moves the lever-type gripper to a position above one side of the roller conveyor 18. The vertical drive mechanism 17 drives the lever-type gripper to descend via the lifting beam 15 until the finger rod 7 is aligned with the gap between the rollers in the roller conveyor 18. After that, the finger drive mechanism 5 moves the gripping finger 4 via the moving frame 3, so that the finger rod 7 is positioned between the rollers in the roller conveyor 18. The gap extends to the underside of the cement bag. After moving into position, the vertical drive mechanism 17 drives the lever-type gripper to rise via the lifting beam 15. During the rising process, the finger rod 7 lifts the cement bag. Then, the lever-type gripper is moved by the moving trolley 14 and the lifting beam 15 to move the cement bag to the loading position. The finger drive mechanism 5 then moves in the opposite direction, driving the finger rod 7 to retract via the moving frame 3. During the movement of the finger rod 7, the cement bag is blocked by the lever 2, so that after the finger rod 7 moves into position, it is gently placed in the loading position to avoid generating dust.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
