Description

A bottle gripper Technical Field

[0001] This application belongs to the field of automated mechanical equipment and relates to an automatic gripping mechanism, specifically a bottle gripper. Background Technology

[0002] In the packaging processes of bottled materials such as liquor and liquid foods, the development of automated equipment has led to increasingly higher requirements for the automation level of production lines. The process of gripping bottles and placing them into boxes has been replaced by mechanical clamps instead of manual operation. However, traditional bottle grippers are usually made of rigid materials (such as ordinary plastic or metal), which are prone to deformation of the gripping teeth during frequent use, resulting in uneven clamping force, potentially scratching the surface of the glass bottle or damaging the bottle neck seal. Some non-standard bottle grippers have poor compatibility with the bottle body, exhibiting problems such as loosening and slippage, especially with irregularly shaped bottles (such as wide-mouth bottles and narrow-necked bottles). Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this application proposes a bottle gripper that ensures stable and reliable bottle gripping, proper bottle positioning, and no damage to the bottle cap.

[0004] The technical problem solved by this application is achieved through the following technical solution:

[0005] A bottle gripper includes a swing rod, a central pressure rod, a gripper assembly, a bottle gripping guide rod, and a gripper positioning sleeve. The swing rod is limited and mounted on a fixed bracket. The other end of the swing rod is connected to the central pressure rod via a hinge. The lower end of the central pressure rod is connected to the gripper assembly. The lower end of the fixed bracket is fixedly mounted with the bottle gripping guide rod, which has a vertical through hole. The central pressure rod coaxially passes through the vertical through hole of the bottle gripping guide rod. As the swing rod swings, the central pressure rod can drive the gripper assembly to move, and the central pressure rod moves up and down along the bottle gripping guide rod.

[0006] Furthermore, a gripper positioning sleeve is connected to the lower end of the bottle-gripping guide rod, and the gripper assembly is limited and connected to the gripper positioning sleeve.

[0007] Furthermore, the central pressure rod cooperates with the gripper positioning sleeve to enable the gripper assembly to open and close. The diameter of the lower end of the central pressure rod is smaller than that of the upper part, and a slope transition is provided between the lower end of the pressure rod and the main body of the central pressure rod.

[0008] Furthermore, a nylon pressure block is fixedly installed on the outer periphery of the middle part of the central pressure rod, and a claw spring is fitted on the outer periphery of the upper part of the central pressure rod. The lower end of the claw spring abuts against the nylon pressure block, and the upper end of the claw spring abuts against the upper part of the bottle gripping guide rod.

[0009] Moreover, the gripper assembly includes gripper swing arms, gripper rubber sleeves, gripper springs, and rolling bearings. Multiple gripper swing arms are arranged around the outer periphery of the central pressure rod. The gripper swing arms swing synchronously relative to each other in the direction of the axis of the central pressure rod. The lower end of the gripper swing arms can clamp the mouth of the wine bottle.

[0010] Furthermore, gripper rubber sleeves are fixedly installed at the lower ends of the gripper swing arms.

[0011] Furthermore, a guide sleeve is provided in the middle of the gripper positioning sleeve, and the guide sleeve has a vertical central hole. The central pressure rod passes through the central hole of the guide sleeve coaxially and can move up and down. The middle of each gripper arm is hinged to the guide sleeve by a pin. A gripper spring is connected to the lower part of each gripper arm. The gripper spring abuts between the gripper arm and the guide sleeve. A rolling bearing is connected to the upper end of each gripper arm. The rolling bearing rotates and abuts against the central pressure rod.

[0012] Moreover, there are four gripper arms that are evenly spaced apart.

[0013] The advantages and positive effects of this utility model are:

[0014] This invention employs a spring buffer and guide slide design, achieving flexible clamping through the sliding connection between the fixed plate and the upright plate, combined with the elastic deformation of the spring. This structure can quickly grasp box-shaped objects while avoiding deformation or damage caused by excessive clamping. The gripper uses a four-lobed clamp with mutually perpendicular grippers, ensuring precise and highly synchronized movements, guaranteeing stable and reliable bottle gripping, centering the bottle position without damaging the cap, and providing stable gripping with the bottle body vertical and without swaying.

[0020] To make the objectives, technical solutions, and advantages of this application clearer and easier to understand, the application will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0021] A bottle gripper, as shown in Figure 1, includes a swing rod 1, a central pressure rod 6, a gripper assembly 4, a bottle gripping guide rod 2, and a gripper positioning sleeve 3. The swing rod 1 is fixedly mounted on a fixed bracket 7. One end of the swing rod 1 is connected to a drive mechanism (not shown in the figure), and the other end of the swing rod 1 is connected to the central pressure rod 6 via a hinge. The lower end of the central pressure rod 6 is connected to the gripper assembly 4, which is used to grip the mouth of a wine bottle 5. As the swing rod swings, the central pressure rod 6 can drive the gripper assembly 4 to move up and down.

[0022] A bottle-gripping guide rod 2 is fixedly mounted at the lower end of the fixed bracket 7, and a vertical through hole is provided inside the bottle-gripping guide rod 2; the central pressure rod 6 coaxially passes through the vertical through hole of the bottle-gripping guide rod 2, and the central pressure rod 6 moves up and down coaxially along the bottle-gripping guide rod 2; a gripper positioning sleeve 3 is connected to the lower end of the bottle-gripping guide rod 2, and the gripper assembly 4 is limited to the gripper positioning sleeve 3. The gripper positioning sleeve 3 is provided with a limiting structure that can limit the movement of the gripper assembly 4, so that the gripper movement is stable and reliable and avoids shaking.

[0023] Referring to Figure 2, the central pressure rod 6 can accurately reciprocate up and down. A nylon pressure block 22 is fixedly installed on the outer periphery of the middle part of the central pressure rod 6, and a claw spring 41 is fitted on the outer periphery of the upper part of the central pressure rod 6. The lower end of the claw spring 41 abuts against the nylon pressure block 22, and the upper end of the claw spring 41 abuts against the upper annular stepped surface of the bottle gripping guide rod 2. The claw spring 41 maintains a preload force, driving the central pressure rod 6 to maintain a downward movement tendency, which is used to reset the central pressure rod 6 after it completes the upward movement.

[0024] Referring to Figures 2 and 3, the central pressure rod 6 cooperates with the gripper positioning sleeve 3 to enable the gripper assembly 4 to open and close. The diameter of the lower end 61 of the central pressure rod 6 is smaller than that of the upper part, and a slope transition is provided between the lower end 61 of the pressure rod and the main body of the central pressure rod 6.

[0025] The gripper assembly 4 includes a gripper swing arm 43, a gripper rubber sleeve 42, a gripper spring 41, and a rolling bearing 45. Multiple gripper swing arms 43 are arranged around the outer periphery of the central pressure rod 6. In this embodiment, four gripper swing arms 43 are evenly spaced. The gripper swing arms 43 swing synchronously relative to each other in the direction of the axis of the central pressure rod 6. The lower end of the gripper swing arm 43 can clamp the bottle mouth of the wine bottle 5. In order to prevent damage to the bottle mouth, a gripper rubber sleeve 42 is fixedly installed at the lower end of each gripper swing arm 43.

[0026] The specific installation structure of the gripper arm 43: A guide sleeve 44 is provided in the middle of the gripper positioning sleeve 3. The guide sleeve 44 is provided with a vertical center hole. The center pressure rod 6 passes through the center hole of the guide sleeve 44 coaxially and can move up and down. The middle of each gripper arm 43 is connected to the guide sleeve 44 by a pin. A gripper spring 41 is connected to the lower part of each gripper arm 43. The gripper spring 41 abuts between the gripper arm 43 and the guide sleeve 44. A rolling bearing 45 is connected to the upper end of each gripper arm 43. The rolling bearing 45 rotates and abuts against the center pressure rod 6.

[0027] During operation: the central pressure rod 6 moves up and down, and the rolling bearing 45 remains in contact with the outer wall of the central pressure rod 6.

[0028] When the central pressure bar 6 moves upward until the lower end 61 of the pressure bar moves to the position of the rolling bearing 45, the upper part of the gripper arm 43 swings in the direction of the central pressure plate axis, and the gripper spring 41 pushes the lower part of the gripper arm 43 to swing away from the central pressure plate axis. Multiple gripper arms 43 move synchronously, thereby opening the gripper assembly 4.

[0029] When the central pressure bar 6 moves downward, the upper part of the gripper arm 43 swings away from the axis of the central pressure plate, and the gripper spring 41 pushes the lower part of the gripper arm 43 to swing closer to the axis of the central pressure plate. Multiple gripper arms 43 move synchronously, thereby clamping the gripper assembly 4.

[0030] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
